The Efficacy of Outsourced Employment Services for Adults Exiting Australian Prisons

Crime rates in Australia have declined or been steady over the past decade yet prison populations are at all-time highs. Similarly, unemployment rates have been low but unemployment for those ex-prisoners seeking work is very high. In this paper, we draw on the findings of an Australia-wide survey of government-funded employment service providers who support working-aged Australians including ex-prisoners in their search for work. We find that the heterogeneity of the needs of ex-prisoners coupled with the frugality and inflexibility of government policies and practices frustrates the abilities of these agencies to provide services to this target group.

Foreign outsourcing collaboration within a developing economy's perspective: A case of the Pakistani textile industry

This paper develops an outsourcing collaboration model from a firm's perspective operating in a developing economy. The model considers that producers of the final goods residing in a developed country, and operators of manufacturing plants in a developing country collaborate with each other. The final goods producer supplies headquarter services for the production of intermediate goods in the developing country. The operators of manufacturing plants also supply their services in the domestic economy. This arrangement leads to foreign outsourcing collaborations (FOC) between firms of developed country and developing country. The operators of manufacturing plant maximize revenue subject to the cost constraint. The first order conditions suggests that an increase in wages of skilled labor, price of domestic inputs, and cost of production deter FOC. On the other hand, an increase in demand for and price of foreign headquarter services increases the FOC. Empirical analysis based on data collected from 217 clothing (textile and apparel) firms in the city of Faisalabad (Pakistan) reveals that an increase in wage to labor-productivity ratio reduces FOC. An improvement in skilled of the labor and foreign headquarter services give rise to FOC, whereas an increase in economies-of-scope enhances FOC. Additionally, an inverted U-shaped relationship is found between the cost of production and FOC, which shows that at the initial stage, the firm's cost of production increases with an increase in the level of FOC, but soon after the tipping point, the firm's cost starts decreasing with a further increase in FOC.

The self online: When meaning-making is outsourced to the cyber audience

This study examines the cyber audience's perception of social media users' persona based on their online posts from a cognitive meaning-making perspective. Participants (N = 158) answered questions about their personal characteristics and provided their 20 most recent Facebook status updates. Two groups of viewers, who viewed either the text-only or multimedia version of the status updates, answered questions about the Facebook users' personal characteristics. The viewers' perceptions of Facebook users deviated from the users' self-perceptions, although user characteristics that serve social motives were more accurately perceived. Multimedia viewers were more accurate than text viewers, whereas the latter showed a greater consensus. Gender and ethnic differences of Facebook users also emerged in online person perceptions, in line with gendered and cultured characteristics. These findings shed critical light on the dynamic interplay between social media users and the cyber audience in the co-construction of a digitally extended self.

The optimal size of territorial units in the outsourcing of waste service: An empirical approach

This study provides new insights into the relation between the size of the territorial units for which the provision of waste services is entrusted to external operators and their efficiency. The need for a deeper investigation of this relation arises from the fact that on the one hand, the European Union is pushing its Member States towards the adoption of laws aimed at ensuring competition for the market whenever competition in the market is possible; on the other, both the theoretical and the empirical literature cautions policymakers against the risks associated with contracting out. This problem is addressed here through an efficiency analysis of Italian municipalities in the organization of waste services. The stochastic frontier analysis (SFA) is applied to estimate efficiency scores for the municipalities. Then, a regression analysis is carried out to investigate the relation between the efficiency scores and the size of the municipality. This analysis has been carried out using data on a sample of 6,916 Italian municipalities (87.39% of the entire population) for the year 2019. The method adopted here can also support regulatory authorities in defining the size of the territorial units in which other types of local public service should be outsourced.

For-profit outsourcing and its effects on placement stability and locality for children in care in England, 2011-2022: A longitudinal ecological analysis

BACKGROUND

The responsibility of local authorities in England to provide children in care with stable, local placements has become increasingly difficult due to the rising number of children in need of care and a shortage of available placements. It is unclear if the trend of outsourcing children's social care to private companies has exacerbated this challenge. This paper examines how the outsourcing of children's social care to the private market has influenced placement locality and long-term stability over time.

METHODS

We created a novel dataset of multiple administrative data sources on the outsourcing, placement locality and stability, and characteristics of children in care between 2011 and 2022. We conducted time-series fixed-effects regression analysis of the impact of for-profit outsourcing on placement locality and stability from 2011 to 2022.

RESULTS

Our fully adjusted models demonstrate that for-profit outsourcing is consistently associated with more children being placed outside their home local authority and greater placement instability. We found that an increase of 1 % point of for-profit outsourcing was associated with an average increase of 0.10 % points (95 % CI 0.02-0.17; p = 0.01) more children experiencing placement disruption, and 0.23 % points (95 % CI 0.15-0.30; p < 0.001) more children being placed outside their home local authority. We estimate that an additional 17,001 (95 % CI 9015-24,987) out-of-area placements can be attributed to increases in for-profit provision.

DISCUSSION

Our analyses show that placement stability and distance have deteriorated or stagnated over the last decade, and that the local authorities that rely most on outsourcing have the highest rates of placement disruptions and out-of-area placements.

Outsourcing practice-based education: The role of industry representatives and implications for clinical expertise

In an era of significant human and fiscal constraints, hospitals increasingly rely on industry representatives to fill gaps related to practice-based education. Given their dual sales and support functions, the extent to which education and support functions are, or ought to be, fulfilled by industry representatives is unclear. We conducted an interpretive qualitative study at a large, academic medical centre in Ontario, Canada, during 2021-2022, interviewing 36 participants across the organization with direct and varied experiences with industry-delivered education. We found that ongoing fiscal and human resource challenges prompted hospital leaders to outsource practice-based education to industry representatives, which created an expanded role for industry beyond initial product rollouts. Outsourcing, however, generated downstream costs to the organization and undermined the goals of practice-based education. To attract and retain clinicians, participants advocated for re-investment in practice-based education in-house, with a limited and supervised role for industry representatives.

Fuzzy comprehensive evaluation and quantitative weight analysis in structure management of human resources

This research delves into the application effects of Fuzzy Comprehensive Evaluation (FCE) and quantitative weight analysis in the structure management of human resources (SMHR) to optimize the structure management. The research begins by analyzing the existing problems in SMHR, such as incomplete performance feedback and error-prone outsourcing decisions. By leveraging human resource management (HRM) characteristics, the researchers construct the SMHR evaluation index system. The Analytical Hierarchy Process (AHP) is employed to establish a hierarchical human resource structure model to determine the relative weight of each HRM indicator. Subsequently, the FCE method is utilized to build an SMHR optimization model, which is then scrutinized and assessed by means of an example. The findings indicate that the consistency ratio (C.R.) values of the first and second-level evaluation factors of the constructed model are less than 0.1, thus passing the consistency test and demonstrating credibility. Ultimately, the research effectively grades SMHR in the enterprise through the analysis of HRM optimization. Accordingly, this research presents a set of optimization suggestions and measures, including the establishment of a professional HRM operation team, acceleration of the construction of a professional talent team, enhancement of the intelligent level of the HRM center, and transition towards digital sharing. These proposed measures can serve as valuable experimental references for the optimization and improvement of HRM structures in future enterprises.

Impact of agricultural production outsourcing services on carbon emissions in China

Increasing food output while reducing agricultural carbon emissions (ACE) is a major challenge to achieving green agriculture in China. Previously unexplored research regarding the relationship between agricultural production outsourcing services (APOS) and ACE is investigated using household microsurvey data in China and econometric methods, and the influencing mechanism is also tested empirically. The results reveal that APOS increases the total ACE and reduces ACE per unit area. The mechanism test shows that APOS are beneficial to the expansion of rice planting areas and farmers' adoption of agricultural green production techniques. The increasing effect of rice planting area on ACE was greater than the decreasing effect of green production techniques. In the future, China should accelerate the selection and breeding of rice varieties with low carbon emissions to reduce the increase of ACE caused by large-scale land management in the process of APOS development. Policy support and subsidies should be strengthened for APOS organizations to purchase green production techniques, so as to further drive farmers to adopt green production techniques and reduce ACE. It is also necessary for China to encourage small-scale farmers to outsource their agricultural production activities to APOS organizations. The role of collective action consciousness of agricultural production in increasing the supply capacity of APOS organizations should be enhanced.

Strategy and additive technologies as the catalyst for outsourcing, process innovation and operational effectiveness

PURPOSE

There is rising interest in Industry 4.0 as a factor in the competitiveness of the organization. Although many companies are aware of the importance of Industry 4.0, the development of such initiatives in Colombia is slow. Consequently, this research investigates the impact of additive technologies as part of the Industry 4.0 concept on operational effectiveness and, therefore, the competitiveness of the organization and tries to establish the factors that hinder the adequate implementation of such new, innovative technologies.

DESIGN/METHODOLOGY/APPROACH

Structural equation modeling was used to analyze the antecedents and outcomes of operational effectiveness. To this end, 946 usable questionnaires were collected from managers and personnel from Colombian organizations.

FINDINGS

Initial findings show that management is aware of Industry 4.0 concepts and implements strategies for such initiatives. Nevertheless, neither process innovation nor additive technologies have a significant impact on operational effectiveness and therefore on the competitiveness of the organization.

PRACTICAL IMPLICATIONS

The implementation of new innovative technologies requires the closure of the digital gap between urban and rural areas and between large and medium and small enterprises. Similarly, the concept of Industry 4.0 as a new, innovative manufacturing concept requires a transversal implementation to increase the competitiveness of the organization.

ORIGINALITY/VALUE

The value of this paper lies in discussing the current technological and human capabilities and strategies that Colombian organizations, as an example of a developing nation, should improve to leverage the benefits of Industry 4.0 to remain competitive. The results are probably generalizable to other regions in developing countries throughout the world.

Selection of outsourcing logistics providers in the context of low-carbon strategies

As more attention is given to climate change and sustainable development in China, enterprises start to care about carbon emissions related to their supply chains. One important issue faced by an enterprise is to select a logistics provider who can provide a high-quality service with low carbon levels. To solve this issue, this paper proposes a selection criterion from the perspective of low carbon levels based on previous studies. The selection criterion consists of comprehensive strength, financial status, market competitiveness, development potential and low carbon level. Next, this paper applies a combined method of information entropy and grey correlation vlsekriterijumska optimizacija i kompromisno resenje (VIKOR) model to evaluate the proposed selection criterion. Subsequently, this paper took company S and its four logistics providers as a case study to check the applicability of our proposed selection method and to illustrate how to use it. Sensitivity analysis and comparative analysis are also conducted. Related managerial insights are also proposed based on the evaluation results. One finding of this paper is to establish a decision-making framework to evaluate logistics suppliers under the new background of 'emission peak and carbon neutrality'.

Impact of outsourced machinery services on farmers' green production behavior: Evidence from Chinese rice farmers

As an important part of agricultural socialization services, outsourced machinery services are of great significance for promoting the green development of agriculture. Using the field survey data of 1080 rice growers in Sichuan Province, this paper empirically analyzes outsourced machinery services' impact and role path on farmers' green production behavior. Further, it analyzes the difference in influence from the perspective of group heterogeneity. The research results show that: (1) The outsourced machinery services significantly impact farmers' adoption of no-tillage technology, organic fertilizer application technology, and straw returning technology. The conclusion is still stable after considering endogeneity. (2) The outsourced machinery services indirectly affect farmers' green production behavior by promoting off-farm employment and expanding the scale of farmland. (3) The impact of outsourced machinery services on farmers' green production behavior is not significant in the male group and the group whose households own agricultural machinery. In conclusion, the study proposes to increase assistance to outsourced machinery services providers and encourage service entities to actively publicize and popularize green production technologies while providing services, to play an influential role in guiding and educating farmers.

Product outsourcing policy for a sustainable flexible manufacturing system with reworking and green investment

Production of defective products is a very general phenomenon. But backorder and shortages occur due to this defective product, and it hampers the manufacturer's reputation along with customer satisfaction. That is why, these outsourced products supply, a portion of required products for in-line production. This study develops a flexible production model that reworks repairable defective products and outsources products to prevent backlogging. A percentage of total in-line production is defective products, which is random, and those defective products are repairable. A green investment helps the reworking process, which has a direct impact on the market demand for products. A classical optimization solves the profit maximization model, and a numerical method proves the global optimal solutions. Sensitivity analysis, managerial insights, and discussions provide the highlights and decision-making strategies for the applicability of this model.

Outsourcing and children's social care services: an observational longitudinal analysis of inspection outcomes among English children's homes and local authorities

BACKGROUND

Most children's social care services in England are operated by for-profit companies, but the implications of this development are not well understood. We aimed to evaluate the associations between for-profit outsourcing and quality of service provision among local authorities and children's home providers in England, UK.

METHODS

We did an observational longitudinal analysis of inspection outcomes among English children's homes and local authorities. We created and analysed a novel, longitudinal dataset of inspections from Ofsted (ie, the independent regulator of children's social care in England) over a period of 7 years (2014-21; n=13 452). We also analysed the association between Ofsted local authority ratings (n=147) and the use of for-profit outsourcing.

FINDINGS

We found that for-profit children's home providers are significantly more likely to be rated of lower quality than both public and third sector services across all provider level Ofsted inspection domains. For example, for-profit providers have 33·7% lower odds (odds ratio [OR] 0·663; 95% CI 0·522-0·842) than local authority providers of being rated "Outstanding", "Good", or "Requires Improvement", as opposed to "Inadequate" in the main "Overall Experiences" Ofsted category. For-profit services also violate more legal requirements (OR 0·380 [95% CI 0·186-0·575]) and receive more recommendations (0·391 [0·242-0·540]) than local authority providers. These findings are robust to model specification and consistent over the full analysed period. Further, we found provisional evidence that local authority Ofsted ratings are negatively correlated with the percentage of for-profit outsourcing, suggesting that poorly performing local authorities tend to outsource a greater amount of their services than well performing local authorities.

INTERPRETATION

Our findings are of considerable concern given the focus of these services on society's most vulnerable service users. However, caution is needed in terms of regulating the sector going forward, as the role of for-profit providers cannot be replaced without substantial coordination and long-term planning.

Evidence on outsourcing dialysis services: a scoping review

INTRODUCTION

Chronic kidney disease represents an important health problem, due to its high incidence and prevalence, as well as its significant morbidity and mortality and socioeconomic cost.

AIMS

compare the effectiveness and economic consequences of outsourcing versus hospital dialysis.

METHOD

A scoping review, for which different databases were consulted, using controlled and free terms. Those articles that compared concerted versus in hospital dialysis in terms of effectiveness were included. Likewise, those publications that compared, in the Spanish field, the cost between both modes of service provision and the public price rates of the different Autonomous Communities were included.

RESULTS

11 articles were included in this review: 8 on comparison of effectiveness, all of them in the USA, and 3 on costs. A higher rate of hospitalization was observed in subsidized centers, but no differences in mortality were observed. Additionally, greater competition among providers was associated with lower hospitalization rates. The cost studies reviewed show that hospital hemodialysis is more expensive than in subsidized centers, due to the structural costs. The data of the public rates of the different Autonomous Communities show a wide heterogeneity in the payment of the concerts.

CONCLUSIONS

the coexistence in Spain of public and subsidized centers, the variability in the provision and costs of dialysis techniques, and the low of evidence on the effectiveness of outsourcing treatment show all the need to continue promoting strategies that result in improvement in the care for Chronic Kidney Disease.

Outsourcing Intersystem Crossing without Heavy Atoms: Energy Transfer Dynamics in PyridoneBODIPY-C60 Complexes

The excited state dynamics in two fully characterized pyridoneBODIPY-fullerene complexes were investigated using time-resolved spectroscopy. Photoexcitation was initially localized on the pyridoneBODIPY chromophore. The energy was rapidly transferred to the fullerene, which subsequently underwent ISC to form a triplet state and returned the energy to the pyridoneBODIPY via triplet-triplet energy transfer. This ping-pong energy transfer mechanism resulted in efficient (>85%) overall conversion of the excited state pyridoneBODIPY constituent despite a complete lack of ISC in the pyridoneBODIPY in the absence of the fullerene partner. The small difference in attachment chemistry for the fullerene did not impact the initial singlet energy transfer. However, the N-methylpyrrolidine bridge did slow both the triplet-triplet energy transfer and the ultimate relaxation rate of the final triplet state when compared to an isoxazole-based bridge. The rates of each step were quantified, and computational predictions were used to complement the proposed mechanism and energetics. The result demonstrated efficient triplet sensitization of a strong chromophore that lacks significant spin-orbit coupling.

Do Disease and Pest Control Outsourcing Services Reduce Arable Land Abandonment? Evidence from China

Arable land abandonment has been occurring in China in recent years. Although an emerging number of studies have investigated the impacts of urbanization and labor migration on arable land abandonment, little is known about what roles agricultural outsourcing services play in reducing arable land abandonment. Based on the data from the China Labor-force Dynamics Survey (CLDS) in both 2014 and 2016, this study employs a two-stage least squares method to address the potential endogeneity issue and sheds some light on the impact of agricultural outsourcing services for controlling disease and pests in arable land abandonment in China. The empirical results show that disease and pest control outsourcing services (DPCOS) significantly decrease the size of household-level arable land abandonment by 6.59% on average. More specifically, DPCOS mainly reduce the arable land abandonment in regions with the labor shortages, while this does not lead to a significant decrease in arable land abandonment in regions characterized by poor soil quality and steep slopes. Therefore, we may conclude that DPCOS could contribute to the reuse of farmlands suitable for cultivation and the exit of farmlands unsuitable for cultivation.

Group key agreement protocol for edge computing in industrial internet

Industrial internet security is a critical component of cyberspace safety. Furthermore, the encryption protocol is a critical component of cyberspace security. Due to the rapid development of industrial internet and edge computing, increasingly more devices are outsourcing their data to cloud servers to save costs. Edge devices should have a secure session key to reduce communication costs and share information. However, most key generation and storage are completed by a centralized third-party organization, which carries some security risks. In this context, this paper will propose a lightweight multi-dimensional virtual iteration of the group key agreement protocol. Group key agreement protocol allows for one-at-a-time encryption and timely key updates without the involvement of a trusted third party, and each device in the network can agreement a large number of keys. According to the analysis of this protocol, it has high security, rapid computation speed, and little storage space.

Towards dealing with commonly occurring requirements engineering process issues during software development outsourcing

Due to specific advantages, the volume of Software Development Outsourcing (SDO) is rapidly increasing. Because of challenges arising from the Requirements Engineering (RE) process, the anticipated benefits of SDO are not achieved in case of several projects. The objective of this research work is to recommend RE practices for addressing the commonly arising RE process issues in the case of SDO. For this reason, a thorough literature review has been undertaken, as well as two questionnaire surveys have been performed with skilled SDO industry practitioners. The surveys have been done by utilizing semi-supervised style and employing Convenience Sampling method. The 50 percent rule and a four-point Likert Scale have also been used to determine the advantages of RE practices for dealing with the issues. A comprehensive list of 147 RE practices has been extracted by conducting a Focus Group session. Furthermore, the 147 RE practices have been ranked by applying Numerical Assignment and Hundred Dollar Techniques during two Focus Group sessions. The detection and adaptation of RE practices aids in enhancing the SDO RE process, evading SDO failures, and achieving the associated SDO advantages.

Outsourcing health-care services to the private sector and treatable mortality rates in England, 2013-20: an observational study of NHS privatisation

BACKGROUND

The effects of outsourcing health services to for-profit providers are contested, with some arguing that introducing such providers will improve performance through additional competition while others worry that this will lead to cost cutting and poorer outcomes for patients. We aimed to examine this debate by empirically evaluating the impact of outsourced spending to private providers, following the 2012 Health and Social Care Act, on treatable mortality rates and the quality of health-care services in England.

METHODS

For this observational study, we used a novel database composed of parsable procurement contracts between April 1, 2013, and Feb 29, 2020 (n=645 674, value >£25 000, total value £204·1 billion), across 173 clinical commissioning groups (CCGs; regional health boards) in England. Data were compiled from 12 709 heterogenous expenditure files primarily scraped from commissioner websites with supplier names matched to registers identifying them as National Health Service (NHS) organisations, for-profit companies, or charities. We supplemented these data with rates of local mortality from causes that should be treatable by medical intervention, indicating the quality of health-care services. We used multivariate longitudinal regression models with fixed effects at the CCG level to analyse the association of for-profit outsourcing on treatable mortality rates in the following year. We used the average marginal effects to estimate total additional deaths attributable to changes in for-profit outsourcing. We provided alternative model specifications to test the robustness of our findings, match on background characteristics, examine the potential impact of measurement error, and adjust for possible confounding factors such as population demographics, total CCG expenditure, and local authority expenditure.

FINDINGS

We found that an annual increase of one percentage point of outsourcing to the private for-profit sector corresponded with an annual increase in treatable mortality of 0·38% (95% CI 0·22-0·55; p=0·0016) or 0·29 (95% CI 0·09-0·49; p=0·0041) deaths per 100 000 population in the following year. This finding was robust to matching on background characteristics, adjusting for possible confounding factors, and measurement error in our dataset. Changes to for-profit outsourcing since 2014 were associated with an additional 557 (95% CI 153-961) treatable deaths across the 173 CCGs.

INTERPRETATION

The privatisation of the NHS in England, through the outsourcing of services to for-profit companies, consistently increased in 2013-20. Private sector outsourcing corresponded with significantly increased rates of treatable mortality, potentially as a result of a decline in the quality of health-care services.

Privacy-Preserving Outsourcing Algorithms for Multidimensional Data Encryption in Smart Grids

With the development of the Internet of Things, smart grids have become indispensable in our daily life and can provide people with reliable electricity generation, transmission, distribution and control. Therefore, how to design a privacy-preserving data aggregation protocol has been a research hot-spot in smart grid technology. However, these proposed protocols often contain some complex cryptographic operations, which are not suitable for resource-constrained smart meter devices. In this paper, we combine data aggregation and the outsourcing of computations to design two privacy-preserving outsourcing algorithms for the modular exponentiation operations involved in the multi-dimensional data aggregation, which can allow these smart meter devices to delegate complex computation tasks to nearby servers for computing. By utilizing our proposed outsourcing algorithms, the computational overhead of resource-constrained smart meter devices can be greatly reduced in the process of data encryption and aggregation. In addition, the proposed algorithms can protect the input’s privacy of smart meter devices and ensure that the smart meter devices can verify the correctness of results from the server with a very small computational cost. From three aspects, including security, verifiability and efficiency, we give a detailed analysis about our proposed algorithms. Finally, through carrying out some experiments, we prove that our algorithms can improve the efficiency of performing the data encryption and aggregation on the smart meter device side.

Outsourcing Transcription: Extending Ethical Considerations in Qualitative Research

Research ethics considerations foreground minimising harm to participants. Whilst increasing attention is being paid to researcher vulnerabilities, little has been written about transcriptionists, who can potentially experience emotional distress and vicarious trauma. In this article, we highlight ethical considerations when outsourcing audio for transcription as part of the RE:CURRENT (REcurrent miscarriage: evaluating CURRENT services) Project. Through qualitative interviews, we explored the perspectives of those involved in the management/delivery of services, and women and men who experienced recurrent miscarriage (N = 62). We put distress protocols in place for participants, researchers and the transcriptionist, and adopted a research team approach with the professional transcriber. The transcriptionist highlighted the isolated nature of the role; how researchers often did not brief her when commissioning work, and how the personal impacts of this work were rarely considered. Researchers and ethics committees should consider ethical responsibilities to 'do no harm' when it comes to transcriptionist wellbeing.

Implications of a Carbon Tax Mechanism in Remanufacturing Outsourcing on Carbon Neutrality

Many governments have imposed methods such as a carbon tax that aim to even out the negative effects of carbon emissions. The taxes levied on different agents lead to different make-buy decisions for production structures and different environmental outcomes. Some original equipment manufacturers (OEMs) outsource remanufacturing to independent remanufacturers (IRs). Thus, a question arises: What are the implications of carbon taxes levied on different agents on remanufacturing outsourcing decisions? To answer this question, we developed two models: (1) acting as common brand owners, OEMs can be taxed for both new and remanufactured products, or (2) acting as different emitters for production and remanufacturing, OEMs are taxed for new products; however, all carbon taxes related to remanufacturing are levied on IRs. Our analysis reveals that, regarding economic performance, firms should undertake a carbon emission tax on their own initiative because this allows the taxpayer to choose more units for its preferred products and leaves its rivals at a huge disadvantage. Moreover, regarding environmental sustainability, carbon emission taxes indeed lead to mitigating the effects of carbon emissions per unit; however, environmental agencies should also pay attention to reducing the total carbon emissions by limiting the volume effects.

Carbon Emission Constraint Policy in an OEM and Outsourcing Remanufacturer Supply Chain with Consumer Preferences

Carbon emission reduction has been a consensus goal for most countries to achieve environmental sustainability. The use of carbon emission trading policies has been generally considered by the governments. Remanufacturing, as an effective way to reduce carbon emission, is incorporated together with the tool of carbon emission policy to construct a low-carbon supply chain in this paper. We analyze the carbon emission reduction and profit maximization problem among enterprises of original equipment manufacturers (OEMs) and their outsourcing remanufacturers, integrating the impact of the carbon emission constraint policy and the carbon market. Considering consumer preferences on low-carbon products and recycling rates of waste products, we construct a Stackelberg game model (dominated by the OEM) and analyze the impact of a carbon emission constraint policy on sales price, volume, carbon emission, and revenue of new and remanufactured products in the supply chain system. The results suggest that the upper bound set by the government on carbon emission for enterprises positively affects sales volume of new products and negatively affects sales prices of both products. Moreover, the discount rate of carbon emission constraint negatively affects sales volume of new products and positively affects sales prices of both products. Notably, the carbon emission constraint policy has impacts on the production decisions of both manufacturers on an economic scale. When the upper bound of carbon emission is equal to a certain threshold, the OEM could obtain the greatest revenue. The results provide a new perspective for the government to attain the goal of carbon emission reduction and not sacrifice economic growth. Managers in outsourcing remanufacturers and OEMs could also be implicated from our results to collaborate in allocating remanufacturing orders to achieve win-win opportunities between them.

Performance Evaluation of Construction Sub-contractors using Ordinal Priority Approach

The construction industry has been recognized as one of the crucial industries of a country. In large-scale public projects, it is frequently observed that the client, who serves the public, seeks the services of several sub-contractors (project outsourcing firms) to execute projects. It also seeks the consulting firms' services to monitor the progress and performance of these sub-contractors. However, performance evaluation of a large number of sub-contractors is not only a challenging phase but also a source of conflict and mistrust between the evaluators and evaluatees because of the subjectivity in the evaluation process. The current study classifies perceived organizational performance into two streams, arguing that the one involving the opinions from the independent evaluators is more objective than the self-evaluation one. The study also makes a pioneering attempt in post-qualification performance evaluation of sub-contractors through the Ordinal Priority Approach (OPA), a promising multi-attribute decision-making methodology. The deployment of the OPA allows the decision-makers to estimate the weights of the evaluation criteria, the sub-contractors to be evaluated, and the experts who evaluated them simultaneously. Thus, the methodology can minimize the causes of mistrust by uncovering unreliable experts and inappropriate criteria. Also, a novel Relative Performance Index (RPI) has been proposed to standardize the performance evaluation system. The results show that evaluation of the firms does not end at their evaluation as without evaluating the evaluators, such an evaluation is only partially effective.

A Comparative Study of the Effect of Different Carbon-Reduction Policies on Outsourcing Remanufacturing

To facilitate the green transformation of enterprises and realize low-carbon development, governments have adopted the policies of carbon emission constraint and carbon trade to promote enterprises’ low-carbon production. Although the two policies aim to reduce carbon emissions, they have different effects on enterprises’ production. Meanwhile, the development of remanufacturing caters to the low-carbon economy. Therefore, this article establishes the game models between an original equipment manufacturer (OEM) and a remanufacturer under carbon-emission-constraint and carbon-trade policies, analyzing the production decisions of enterprises under different policies to compare the influence of the two policies on outsourcing remanufacturing. The main conclusions of the article are as follows: (1) Both carbon-emission-constraint and carbon-trade policies increase the unit retail price of remanufactured and new products, reducing the new products sales volume. However, the sales volume of remanufactured products only decreases if the discount rate is less than the rate of carbon emissions of the two products. (2) The upper limit of carbon emissions can affect the unit outsourcing cost. The unit cost of outsourcing under the carbon-emission-constraint policy is only higher when the upper limit of carbon emissions is less than a certain threshold, and the discount rate is larger than the proportion of carbon emissions for both products; otherwise, the unit outsourcing cost under the carbon-trade policy is higher. (3) Both policies lessen the total environmental implication. When the upper limit of carbon emissions is less than a particular threshold, the environmental effect of the two manufacturers under the carbon-emission-constraint policy is smaller; otherwise, the environmental impact is smaller under the carbon-trade policy.

Increasing disparities in the embedded carbon emissions of provincial urban households in China

In the context of carbon neutrality and the National Economic Circle Strategy, understanding regional disparities in carbon emissions from household consumption is conducive to regional coordination as well as high-quality and low-carbon development in China. In this study, a multiregional input-output (MRIO) model and structural decomposition analysis (SDA) are adopted to investigate the regional disparity change trends of embedded carbon emissions (ECEs) from urban households and the underlying drivers during the rapid economic development period from 2002 to 2012 in China. The results indicate that the eastern regions tended to have larger increments in total urban household ECEs, while the western regions tended to have faster growth rates. An increasing disparity and evident outsourcing pattern can be observed during the study period. The consumption level had a strong positive effect on urban household ECEs in all of the provinces, while the carbon efficiency, consumption pattern, production structure, and population size had differentiated offsetting effects on urban household ECEs in various provinces. The results obtained in this study are conducive to promoting joint efforts for carbon emission reduction and narrowing regional disparities.

Global trade network and CH4 emission outsourcing

The intensifying globalization contributes to the anthropogenic methane (CH₄) emissions outsourcing, a strong greenhouse gas and harmful air pollutant, through the increasingly complex global trade network. However, the CH₄ flow patterns embodied in global traded goods and services have not been interpreted from the perspective of a complex network. In this paper, we integrate global CH₄ emission inventory from the EDGAR (the Emission Database for Global Atmospheric Research) databases, global multi-regional input-output model from the GTAP database, and complex network analysis to reveal the structural characteristics of the global CH₄ flow network (GCFN). In the GCFN, more than one quarter of the global anthropogenic CH₄ emissions in 2014 are associated with international trade. The top 20 economies contribute to about 70% of the total embodied CH₄ emission flows. The GCFNs mainly consist of tripartite patterns centered on China, the USA and Russia. Some emerging countries, such as Thailand and Brazil, also exhibit dominated positions in different kinds of GCFNs. Moreover, the core-periphery structure of the GCFN confirms the existence of a few hub economies associated with a large amount of CH₄ emissions. The results emphasize the multinational cooperation on global CH₄ emission mitigation, and well-focused mitigation policies should be implemented on some key economies.

An Efficient Privacy-Preserving Public Auditing Protocol for Cloud-Based Medical Storage System

The booming Internet of Things makes smart healthcare a reality, while cloud-based medical storage systems solve the problems of large-scale storage and real-time access of medical data. The integrity of medical data outsourced in cloud-based medical storage systems has become crucial since only complete data can make a correct diagnosis, and public auditing protocol is a key technique to solve this problem. To guarantee the integrity of medical data and reduce the burden of the data owner, we propose an efficient privacy-preserving public auditing protocol for the cloud-based medical storage systems, which supports the functions of batch auditing and dynamic update of data. Detailed security analysis shows that our protocol is secure under the defined security model. In addition, we have conducted extensive performance evaluations, and the results indicate that our protocol not only remarkably reduces the computational costs of both the data owner and the third-party auditor (TPA), but also significantly improves the communication efficiency between the TPA and the cloud server. Specifically, compared with other related work, the computational cost of the TPA in our protocol is negligible and the data owner saves more than 2/3 of computational cost. In addition, as the number of challenged blocks increases, our protocol saves nearly 90% of communication overhead between the TPA and the cloud server.

Revealing spatiotemporal travel demand and community structure characteristics with taxi trip data: A case study of New York City

Urban traffic demand distribution is dynamic in both space and time. A thorough analysis of individuals’ travel patterns can effectively reflect the dynamics of a city. This study aims to develop an analytical framework to explore the spatiotemporal traffic demand and the characteristics of the community structure shaped by travel, which is analyzed empirically in New York City. It uses spatial statistics and graph-based approaches to quantify travel behaviors and generate previously unobtainable insights. Specifically, people primarily travel for commuting on weekdays and entertainment on weekends. On weekdays, people tend to arrive in the financial and commercial areas in the morning, and the functions of zones arrived in the evening are more diversified. While on weekends, people are more likely to arrive at parks and department stores during the daytime and theaters at night. These hotspots show positive spatial autocorrelation at a significance level of p = 0.001. In addition, the travel flow at different peak times form relatively stable community structures, we find interesting phenomena through the complex network theory: 1) Every community has a very small number of taxi zones (TZs) with a large number of passengers, and the weighted degree of TZs in the community follows power-law distribution; 2) As the importance of TZs increases, their interaction intensity within the community gradually increases, or increases and then decreases. In other words, the formation of a community is determined by the key TZs with numerous traffic demands, but these TZs may have limited connection with the community in which they are located. The proposed analytical framework and results provide practical insights for urban and transportation planning.

[Outsourcing of nursing staff costs in psychiatry? : A secondary data analysis of possible effects on the remuneration system in psychiatry]

BACKGROUND

Nursing staff were excluded from the German DRG system for somatic hospital treatment and will be funded separately in the future. In psychiatry and psychosomatic medicine, binding personnel requirements have been defined but there has been no regulation of how these personnel requirements are adequately financed.

OBJECTIVE

The objective of this study was to analyze the costs of inpatient psychiatry and psychosomatic medicine and to evaluate possible effects of funding nursing staff separately.

MATERIAL AND METHODS

This analysis is based on aggregated daily treatment costs of selected hospitals (data year 2018), which annually submit their performance and cost data to the Institute for the Hospital Remuneration System (InEK) for the empirical further development of the remuneration system.

RESULTS

Nursing staff represent the largest cost factor in inpatient psychiatry and psychosomatic medicine. Excluding nursing staff drastically reduces the variance of psychiatric DRG renumeration and even exceeds its proportion of the total costs. After outsourcing nursing costs, psychiatric DRGs achieve only a very limited cost separation.

CONCLUSION

The binding personnel requirements necessitate adequate financing of nursing staff. This raises the debate about the further development of psychiatric remuneration. The question arises as to whether the effort associated with using the psychiatric DRG system justifies its usefulness as an instrument for budgeting when core functions such as cost separation are only given to a limited extent. Alternative approaches to budgeting should also be examined for putting costs and benefits in a better ratio.

A novel approach to data integrity auditing in PCS: Minimising any Trust on Third Parties (DIA-MTTP)

Data Integrity Auditing (DIA) is a security service for verifying the integrity of outsourced data in Public Cloud Storage (PCS) by users or by Third-Party Auditors (TPAs) on behalf of the users. This paper proposes a novel DIA framework, called DIA-MTTP. The major novelty of the framework lies in that, while providing the DIA service in a PCS environment, it supports the use of third parties, but does not require full trust in the third parties. In achieving this property, a number of ideas also have been embedded in the design. These ideas include the use of multiple third parties and a hierarchical approach to their communication structure making the service more suited to resource-constrained user devices, the provision of two integrity assurance levels to balance the trade-off between security protection levels and the costs incurred, the application of a data deduplication measure to both new data and existing data updates to minimise the number of tags (re-)generated. In supporting the dynamic data and deduplication measure, a distributed data structure, called Multiple Mapping Tables (M2T), is proposed. Security analysis indicates that our framework is secure with the use of untrusted third parties. Performance evaluation indicates that our framework imposes less computational, communication and storage overheads than related works.

The role of outsourcing facilities in overcoming drug shortages

BACKGROUND

The Drug Quality and Security Act passed in 2013 created a new voluntary category of compounders, referred to as outsourcing facilities. The regulatory landscape allows these facilities to compound on a larger scale in comparison with the typical compounding pharmacies, which positions them to potentially serve a role in overcoming drug shortages.

OBJECTIVE

The purpose of this article is to identify the number of drug products on shortage as reported by the Food and Drug Administration (FDA) that were also compounded by outsourcing facilities.

METHODS

All current and resolved drug shortages through January 27, 2020, as reported by FDA, were compared with the 503B product reports from July 2018 through June 2019 submitted to FDA by outsourcing facilities. The active pharmaceutical ingredient (API) and dosage form for each product on shortage were compared with the 503B product reports to identify similarities.

RESULTS

There were 344 unique APIs on the FDA drug shortage list and 774 unique APIs on the 503B product reports. After comparison of the APIs on the drug shortage list with those on the product reports, 27% of unique APIs (74 of 272) were included on both lists, and of these, 18% (50 of 272) of the APIs on the drug shortage list were compounded by outsourcing facilities in the same dosage form as what was on shortage.

CONCLUSION

The regulatory landscape positions outsourcing facilities to play an important role in providing access to medications while on shortage. However, when comparing the drugs on shortage as reported by FDA with the 503B product reports, there was minimal overlap. Additional research into why outsourcing facilities are not taking on a larger role in overcoming drug shortages should be explored.

Outsourcing Swimming Education-Experiences and Challenges

In Norway, swimming and lifesaving education (swimming education) is an obligatory part of physical education, with explicit learning aims after grade four. After recent reports of Norwegian pupils achieving low scores in swimming abilities, the Government has outlined strategies for improving swimming education. There is a notable trend toward using external providers in delivering swimming education. This article examines the outsourcing of swimming education in Norwegian primary schools. Eighteen semi-structured interviews were conducted with school leaders, physical education teachers and swimming instructors involved in outsourcing arrangements. The outsourcing was organized through private providers, municipalities, or local swimming clubs. Data were analyzed thematically and separated into highlighted areas of outsourcing practices. The results showed that outsourcing may be a solution for schools that lack staff with swimming experience and knowledge. It also indicates that teacher courses, professional development through collaboration, and strategies for measuring quality would improve swimming education.

Healthchain: A novel framework on privacy preservation of electronic health records using blockchain technology

The privacy of Electronic Health Records (EHRs) is facing a major hurdle with outsourcing private health data in the cloud as there exists danger of leaking health information to unauthorized parties. In fact, EHRs are stored on centralized databases that increases the security risk footprint and requires trust in a single authority which cannot effectively protect data from internal attacks. This research focuses on ensuring the patient privacy and data security while sharing the sensitive data across same or different organisations as well as healthcare providers in a distributed environment. This research develops a privacy-preserving framework viz Healthchain based on Blockchain technology that maintains security, privacy, scalability and integrity of the e-health data. The Blockchain is built on Hyperledger fabric, a permissioned distributed ledger solutions by using Hyperledger composer and stores EHRs by utilizing InterPlanetary File System (IPFS) to build this healthchain framework. Moreover, the data stored in the IPFS is encrypted by using a unique cryptographic public key encryption algorithm to create a robust blockchain solution for electronic health data. The objective of the research is to provide a foundation for developing security solutions against cyber-attacks by exploiting the inherent features of the blockchain, and thus contribute to the robustness of healthcare information sharing environments. Through the results, the proposed model shows that the healthcare records are not traceable to unauthorized access as the model stores only the encrypted hash of the records that proves effectiveness in terms of data security, enhanced data privacy, improved data scalability, interoperability and data integrity while sharing and accessing medical records among stakeholders across the healthchain network.

Treatment flows after outsourcing public insurance provision: Evidence from Florida Medicaid

While politics can determine what public goods are available, elected officials must decide on the method of allocation. Commonly, governments provide public health insurance directly or pay private parties to administer it on their behalf. Such contracting can leverage private sector expertise but also raises agency concerns. In particular, little is known about how private provision of public health insurance impacts medical decision-making and treatment flows for low-income populations. An example comes from the Medicaid program, which has increasingly relied on outside insurers to deliver health services to enrollees. We exploit a large legislative intervention in Florida to show that Medicaid managed care (MMC) organizations generally do not skimp on short-run treatment delivery in the inpatient setting. In fact, patients with severe and chronic illnesses receive more inpatient services under these contracts, especially in relation to managing care transitions. We also document increased competition in the MMC market following the state's policy intervention.

Institutionalising the evaluation function: A South African study of impartiality, use and cost

PURPOSE

This article explores the implications of outsourcing the evaluation function in South Africa, a context where there is a mismatch between evaluation supply and demand. It unpacks the tradeoffs between internal and external evaluation, and challenges some commonly held assumptions about both.

APPROACH

Based on experiences as an internal evaluator, external evaluator, evaluation manager, and building evaluation capacity, the author explores how each role changes when evaluation is a scarce skill, and looks at implications outsourcing has for both the organization, and the evaluation.

FINDINGS

The purpose of the evaluation must drive the decision to outsource. However, with changing models of collaboration, there may be hybrid options that allow organizations to build evaluation capacity.

PRACTICAL IMPLICATIONS

Organisations are faced with a trade-off between commissioning an evaluation, and building internal evaluation capacity. To better understand each approach, it is important to consider the purpose and context of the evaluation. This shifts some commonly held assumptions about internal and external evaluations. Re-examining these assumptions will help organizations make a more informed decision about an evaluation approach.

ORIGINALITY/VALUE

The field of evaluation is particularly concerned with evaluation use. Most of the literature on this has focused on the approach of individual evaluators, and insufficient attention has been paid to the institutional architecture of the evaluation. This article considers how some of the organisational structures around an evaluation contribute to evidence use, and the case study of South Africa also shifts the focus to the central but overlooked role of context in the debate.

Summary of Quality-Control Testing for Sterile and Nonsterile Compounded Preparations, Part 1: Physical and Chemical Testing

Quality control and quality assurance are vital components for successful pharmaceutical compounding. A quality program consists of proper procedures, proper documentation, proper training, and proper testing, both analytical (physical and chemical) and microbiological. Each sterile and nonsterile dosage form has a number of tests that are appropriate and some that can be easily done. Some analytical tests can be conducted in-house and some may require outsourcing. All aspects of the quality program must be documented as well as periodically reviewed and updated. A quality program is constantly being changed and improved as new technology, equipment, and procedures are implemented in the facility. The end result of a quality program should be properly compounded preparations that are safe and effective for patients.

Verifiable fully outsourced attribute-based signcryption system for IoT eHealth big data in cloud computing

The entrance of Internet of Things (IoT) technologies to healthcare industry has impacted the explosion of eHealth big data. Cloud computing is widely considered to be the promising solution to store this data because of the presence of abundant resources at a lower cost. However, the privacy and security of the IoT generated data cannot be ensured as the data is kept far from the owner's phys- ical domain. In order to resolve the underlined issues, a reassuring solution is to adopt attribute-based signcryption (ABSC) due to the desirable cryptographic properties it holds including fine-grained ac- cess control, authentication, confidentiality and data owner privacy. Nonetheless, executing expensive computation such as pairing and modular exponential operations in resource-constrained IoT device platform can be too taxing and demanding. To address the challenges stated above, we proposed in this paper, a more efficient scheme where computation power is borrowed from the cloud server to process expensive computations while leaving simple operations to local users. In order to realize this, trusted attribute authority, signcryptor and designcryptor outsources to the cloud expensive tasks for key gener- ation, signcryption and designcryption respectively. Moreover, validity and correctness of outsourced computations can be verified by employing outsourcing verification server. Security analysis, compar- isons evaluation and simulation of the proposed scheme is presented. The output demonstrates that it is efficient, secure and therefore suitable for application in resource-constrained IoT devices.

[How we see the development of clinical trials from the investigators' side?]

This is a discussion paper on research in clinical pharmacology in the field of psychiatry. In addition to other factors the decline in discovery and development of new drugs in the field of psychiatry and the developments and growing complexity in the field of clinical trial technology, including outsourcing and risk based monitoring, reduced the number of young clinical researchers interested in this important field. The challenges posed by the restructuring within the pharmacological industry - including digitalization - should induce changes in the structure and in the processes of clinical pharmacology research and in the training of clinical research staff members. The approval of esketamine nasal spray for treatment resistant depression by the FDA and the results of research with psychedelics call for more education and training in this specific field.

[IT Outsourcing and Medical Secrecy]

IT Outsourcing and Medical Secrecy Abstract. When medical practices outsource IT work, the requirements of data protection laws and professional secrecy in particular must be taken into account. In terms of data protection laws, outsourcing to third parties requires, among other things, that an agreement is concluded, and that the outsourcing provider only processes the data in the way that the doctor himself is permitted to do. Furthermore, outsourcing must not be prohibited by a legal or contractual obligation to maintain secrecy, such as medical professional secrecy. Professional secrecy has been widely discussed in recent years in connection with the outsourcing of services by physicians. Despite other restrictive positions, however, IT outsourcing should continue to be regarded as permissible if it can be justified on objective grounds, if it remains within the scope of what is customary and necessary for physicians and if appropriate measures are taken to avoid disclosure of personal data.

Outsourcing natural resource requirements within China

Consumption demands are final drivers for the extraction and allocation of natural resources. This paper investigates demand-driven natural resource requirements and spatial outsourcing within China in 2012 by using the latest multi-regional input-output model. Exergy is adopted as a common metric for natural resources input. The total domestic resource exergy requirements amounted to 125.5 EJ, of which the eastern area contributed the largest share of 44.5%, followed by the western area (23.9%), the central area (23.0%) and the northeastern area (8.6%). Investment was the leading final demand category, accounting for 52.9% (66.4 EJ) of national total embodied resource use (ERU). The total trade volumes of embodied resource were equivalent to 69.6% of the total direct resource input (DRI), mostly transferred from the central and western regions such as Inner Mongolia, Shanxi, Shaanxi and Xinjiang to the eastern regions such as Jiangsu, Zhejiang, Guangdong and Shanghai. The northeastern and eastern areas had physical net imports of 1213.5 PJ and 38452.6 PJ, while the central and western inland areas had physical net exports of 6364.5 PJ and 33301.5 PJ, respectively. Shanghai, Beijing, Zhejiang, Jiangsu and Guangdong had prominent ERUs which respectively were 101.6, 12.6, 11.7, 8.4 and 4.3 times of their DRIs. The ERUs of Inner Mongolia, Shaanxi, Shanxi, Ningxia and Guizhou were equal to only 17.6%, 25.3%, 27.9%, 46.0% and 50.2% of their DRIs, respectively. Regional uneven development resulted in imbalanced resource requirements across China. The findings can provide a deep understanding of China's resource-driven economic development mode, and contribute to reducing regional resource footprints and their environment outcomes under the "new normal economy".

[OUTSOURCING OF MEDICAL SERVICES FOR SOLDIERS TO CIVILIAN HEALTH FUNDS]

The Israeli Medical Corps provides a great deal of medical services by its own medical personnel and purchases some services from various civilian suppliers, including public hospitals. Although the IDF has bought hospital services since it's early days, few attempts have been made to purchase primary and secondary medical services for soldiers in rear units. This article presents an analysis of the outsourcing project ("Aviv" project) of medical services for rear units which was operating between the years 2010 - 2014. In this project soldiers chose to receive services from one of the four healthcare funds in Israel. The project is analyzed from two perspectives, military and civilian, based on the personal experience of the author who led the implementation of the project while he was the Surgeon General of the Medical Corps and gained additional experience at a later stage during his positions in Maccabi Healthcare Services. Despite the different policies of the medical corps and the healthcare funds that are described in the article, it is advisable to utilize the civilian infrastructure in Israel to provide soldiers with better medical services. Future projects should consider the lessons learned from the Aviv project and adjust the demands of the Medical Corps from the healthcare funds, so that soldiers will receive similar services to their civilian counterparts. Among other recommendations, the author advises that soldiers will pay copayment and will receive broad services, including the basic basket and complimentary health services.
