Strategic career behaviours among hybrid workers: testing a general European model

Introduction

This study investigates the antecedents and consequences of strategic career management behaviours in a sample.

Methods

A total of 739 employees (Male = 442, 59.8%) with a mean age of 27.64 years (SD = 8.48; Range = [18, 70]), working mostly full-time (n = 398, 53.9%) and with 46.35% of their work being done hybrid-like participated in this study. The study tested perceived self-efficacy, desire for career control and perceived organizational support as predictors of strategic career behaviours. And tested strategic career behaviours as predictors of perceived career control, objective and subjective career success, and career satisfaction.

Results

Results indicate objective career success was not related to the antecedent variables of strategic career behaviours and hence was removed from the model. Regression and mediation analyses demonstrated that perceived self-efficacy and desire for career control are good predictors of the use of strategic career behaviours, but perceived organizational support is not; strategic career behaviours are reasonable predictors of perceived control, and very strong predictors of subjective career success and career satisfaction.

Discussion

Strategic Career Behaviours were found to play only a partial mediating role in the present model suggesting that further analysis is required to determine whether they play a central role in the relationships between the antecedents and consequences in the present model, or whether they should be considered a contributing but merely parallel factor. These results will support career management programs, accounting for idiosyncrasies of hybrid work.

Online and computer-assisted career guidance: Are students prepared for it?

Career services should be a priority for any higher education institution. These structures should be prepared to support the design, implementation, and evaluation of academic and career plans and decisions, providing services properly aligned with students' needs, preferences, and characteristics. The present study addressed these questions by analyzing data from an online survey administered to 361 Portuguese higher education students. Results indicate that most students do not seek support in these structures, despite having various needs, particularly in the scope of exploring the world of work, developing goals and implementing career strategies. Most students are open to the use of online and computer-assisted career guidance, although their preference is for in-person interventions. These results allow Career Offices to identify new directions and opportunities to work with students, while demonstrating their value to the academic community and the labor market.

Chyloperitoneum due to gastric carcinoma: a case report

Chyloperitoneum is a rare manifestation of gastric carcinoma, generally occurring late in the course of the disease with a poor prognosis. We report an unusual case of chyloperitoneum in a patient with gastric carcinoma. A 61-year-old male patient presented with postprandial fullness, nausea and weight loss. The upper gastrointestinal endoscopy demonstrated a stenosing lesion of the esophagogastric junction. A biopsy was made and revealed a signet-ring cell gastric adenocarcinoma. The staging CT scan showed multiple abdominal lymphadenopathies and mild ascites. The patient underwent a staging laparoscopy that revealed a large carcinoma of the gastric cardia and a milky-appearing peritoneal fluid. A peritoneal washing and abdominal drainage were performed. The fluid analysis showed a high concentration of triglycerides, compatible with a chyloperitoneum. The patient started medium chain triglycerides-based diet with good response. This case report emphasizes that chyloperitoneum should be considered when assessing patients with gastric carcinoma.

Avaliou-se a validade de conteúdo da escala, por meio da análise da relevância e clareza dos itens e da relação entre cada item e sua respectiva dimensão. Os resultados indicam qualidades satisfatórias concernentes à relevância (IVC =.991; Kappa =.488), associação entre item e fator (% acordo = 95%) e validade aparente, tendo sido sugeridas melhorias quanto à clareza de alguns itens (IVC =.944; Kappa =.379). Estes resultados justificam o investimento em estudos futuros de validação empírica, nomeadamente através de análises fatoriais.

Psychological Counseling in Portuguese Higher Education: What are the Students’ Needs?

This study explores the counseling needs of students attending Portuguese higher education. Specifically, a convenience sample of 375 students was surveyed online with the Survey of Student Needs. Descriptive results indicated that “overcoming procrastination”, “job search strategies” and “time management skills” were their main concerns. Inferential results indicated differences according to personal and academic information and present living conditions, particularly in regard to personal counseling needs. Also, a linear regression analysis found that gender, academic satisfaction and satisfaction with current living conditions had a predictive effect on counseling needs, and that students had a preference for individual counseling. Conclusions are drawn about the importance of developing interventions targeting specific clients.

Effect of the inoculation of sugarcane silage with Lactobacillus hilgardii and Lactobacillus buchneri on feeding behavior and milk yield of dairy cows

Despite its low NDF digestibility, sugarcane is an option for feeding dairy cattle in tropical regions. We evaluated the effect of sugarcane silages inoculated with CCMA 0170 (LH; an epiphytic bacteria isolated from sugarcane) or with NCIMB 40788 (LB; a commercial strain isolated from temperate grasses) on dairy cow performance and feeding behavior. The microbial inoculums were previously grown in the laboratory to obtain 5 log cfu/g of fresh forage. Nine tons of each inoculated silage and a noninoculated control silage (CON) were harvested from the same field and stored for at least 35 d in experimental 20 × 2.1 × 0.4 m bunker silos. Fifteen Holstein cows in late lactation (336 ± 175 days in milk at the start of the experiment) received the treatments in five 3 × 3 Latin squares with 21-d periods. The diets contained 20% of DM of sugarcane silage and 41% of DM of corn silage. Milk yield was increased from 18.0 kg/d for CON to18.8 kg/d for LH, but LB did not elicit a detectable increase in milk yield (18.1 kg/d). The daily yields of fat, protein, lactose, and total solids were increased by LH. Daily DMI and total tract apparent digestibility of nutrients did not differ among treatments. Both inoculated silages reduced acetate and increased butyrate proportions in ruminal VFA, but only LH silage reduced the acetate to propionate ratio (3.0 vs 3.3). First meal duration was shorter for CON compared to LH and LB. The proportion of daily intake between 0700 and 1300 h tended to be increased, and the proportion between 1900 and 0700 h was reduced by LH. The inoculation of sugarcane silage with affected rumen fermentation profile and feeding behavior of late lactation dairy cows, increasing the yield of milk solids.

Validation of a three-dimensional model about sleep: Habits, personal factors and environmental factors

OBJECTIVES

The present study aims to test the factor structure of two sleep questionnaires and their internal consistency in a sample of adolescents and their respective parents and to evaluate the validity and robustness of a three-dimensional model about sleep, addressing nine subcategories related to sleep habits, personal and environmental factors.

METHODS

Participants were 654 adolescents from Portuguese schools, who completed "My Sleep and I" questionnaire, and 664 parents who completed "My child׳s sleep" questionnaire; to them confirmatory factor analysis was applied.

RESULTS

Confirmatory factor analysis indicate that a nine-factor model has better fit indices compared with the others tested models for both samples (adolescents: χ (2)/df (Chi-square/degrees of freedom)=2.59, Comparative Fit Index (CFI)=.82, Goodness-of-Fit Index (GFI)=.92, Root Mean Square Error of Approximation (RMSEA)=.049, Expected Cross-Validation Index (ECVI)=1.416; Parents: χ (2)/df=2.89, CFI=.85, GFI=.91, RMSEA=.053, ECVI=1.528). Moreover, the comparison of the models through Δχ (2) index (chi-square difference between rival models) indicates a better fit for this model, Δχ (2) (24)=186.5, p<.001 for adolescents and Δχ (2) (24)=209, p<.001 for parents. Also, the three second-order factors have good internal consistency, convergent and discriminant validity for all factors in both samples.

CONCLUSIONS

Results postulate that the three factors and their nine subcategories account for correlations between sleep habits, self-perceptions and knowledge about sleep.

The myostimulating effect of tissue kallikrein on rat uterus

The mechanism of the myostimulating activity of rat tissue kallikrein on rat uterus was re-examined using uterus from kininogen-deficient rats and HOE 140 (D-Arg[Hyp3, Thi5, D-Tic7, Oic8]bradykinin), a specific bradykinin receptor-B2 antagonist. The uterus from kininogen-deficient rats was 50 times less sensitive to rat kallikrein than that from normal rats. HOE 140 (6 to 60 nM) inhibited the contracting effects of bradykinin and of rat kallikrein. Porcine kallikrein had no effect on rat uterus. Bradykinin and rat kallikrein induced a relaxation of rat duodenum. The duodenum from kininogen-deficient rats was 100 times less sensitive to rat kallikrein than the duodenum from normal rats. HOE 140 (0.6 to 3 nM) inhibited the relaxing effects of bradykinin and of kallikrein. Preincubation of rat kallikrein with aprotinin (Trasylol) abolished the effects of kallikrein on smooth muscles. HOE 140 inhibited the amidolytic activity of tissue kallikrein with a Ki value of 220 microM. HOE 140, at micromolar concentrations, suppressed the kininogenase activity of tissue kallikrein. Plasma of deficient rats contained 0.7% of the normal levels of kininogens. After washing the blood vessels with saline, kininogens were present in uterine homogenates but not in duodenal homogenates from both rat strains.(ABSTRACT TRUNCATED AT 250 WORDS)

Cannabinoid receptor binding and agonist activity of amides and esters of arachidonic acid

The cannabinoid receptor in brain (CB1) specifically binds delta 9-tetrahydrocannabinol, the predominant central nervous system-active component of marijuana. An eicosanoid found in brain, N-(2-hydroxyethyl)arachidonylamide (anandamide), binds to CB1 with similar affinity. This report considers structure-activity requirements for a series of novel amides and rigid hairpin conformations typified by N-(2-hydroxyethyl)prostaglandin amides, assayed with phenylmethylsulfonyl fluoride inactivation of esterases/amidases. Arachidonyl esters were 30-fold less potent than N-(2-hydroxyethyl)arachidonylamide, showing a rank order of potency of methyl = ethyl > propyl = isopropyl. Within the N-(hydroxyalkyl)arachidonylamide series, a one-carbon increase in chain length increased the potency 2-fold, but continued extension decreased affinity. Substituting the amide for the N-(2-hydroxyethyl)amide function produced a 4-fold loss of affinity. The N-(propyl)-, N-(butyl)-, and N-(benzyl)arachidonylamide derivatives exhibited a 3-fold increase, no change, and a 5-fold decrease, respectively, in affinity, compared with N-(2-hydroxyethyl)arachidonylamide. Both the methoxy ether and the formamide derivatives suffered > 20-fold loss of potency, compared with N-(2-hydroxyethyl)arachidonylamide. N-(2-Aminoethyl)arachidonylamide interacted poorly with CB1. At 100 microM, N-(2-hydroxyethyl)amide analogs of prostaglandin E2, A2, B2, and B1 failed to alter [3H]CP55940 binding to CB1. N-(2-Hydroxyethyl)arachidonylamide inhibited adenylate cyclase with lesser potency but with similar efficacy, compared with desacetyllevonantradol. Extending the length of the hydroxyalkyl moiety by one carbon increased the apparent potency by 1 order of magnitude. The N-(propyl) derivative exhibited a 5-fold greater potency than did the N-(2-hydroxyethyl) analog. It appears that the bulk and length of the moiety appended to arachidonic acid are more important determinants of affinity for CB1 than is hydrogen-bonding capability.

Trypanosoma rangeli (Tejera, 1920) isolated from a sylvatic rodent (Echimys dasythrix) in Santa Catarina Island, Santa Catarina State: first report of this trypanosome in southern Brazil

A trypanosome strain isolated from a sylvatic rodent (Echimys dasythrix) from Santa Catarina Island (Santa Catarina State, Brazil) was characterized by the following methods: experimental transmission and development in invertebrate and vertebrate hosts, morphometry, cross protection, complement sensitivity, lectin agglutination and isoenzyme profiles. Comparisons were made with standard Trypanosoma cruzi and T. rangeli strains. All methods except isoenzyme analysis led to the identification of the isolate as T. rangeli. The isoenzyme differences found could be explained on the basis of polymorphism. Therefore this is the first report of T. rangeli in southern Brazil, increasing the geographical distribution of this parasite.

[Cineventriculography with radionuclides and intravenous dipyridamole in the prognostic evaluation after acute myocardial infarction]

PURPOSE

To evaluate safety and usefulness of dipyridamole-radionuclide ventriculography (D-RVG), soon after acute myocardial infarction (MI), in the prediction of future cardiac events. Traditionally performed tests were also compared.

PATIENTS AND METHODS

Forty-one patients (4 females) with recent MI underwent rest and dipyridamole (0.58 mg/kg of body weight) radionuclide ventriculography. The criteria for a positive test for ischemia was failure to increase left ventricular ejection fraction in 0.05 from baseline value. All patients had also coronary angiography and 36 patients underwent thallium-201 scintigraphy for comparison. The mean follow-up was 16 +/- 3 months. The following findings were considered future for events: cardiac death, reinfarction, significant angina or heart failure.

RESULTS

During the follow-up 18 of the 20 patients who had cardiac events had shown positive dipyridamole-RVG, as opposed to 5 of 21 event-free patients (p less than 0.01). The ventriculographic criteria for a positive test and dipyridamole left ventricular ejection fraction were the strongest predictors of those medical events (p less than 0.01 and p less than 0.001). Among the 36 patients who had thallium-201 imaging, 16 subsequently had cardiac events and the scans were positive in 82% (p less than 0.01). Twelve (29%) patients experienced reactions during dipyridamole infusion although no fatal complications were noted.

CONCLUSION

Dipyridamole-RVG is relatively safe and a sensitive predictor of future cardiac events soon after acute MI, although additional experience is required before this new technique should be routinely recommended as an alternative approach.

The defect in pulmonary gas transfer in patients with sickle cell disease

Nine patients with sickle cell disease and without concomitant cardiopulmonary illness or acute problems were studied with lung function tests. Besides arterial hemoglobin unsaturation, found in all cases so studied, a slight decrease in PaO2 was also present. The pulmonary gas transfer defect was studied and found to be due mostly to increased right to left shunting, although uneven ventilation/perfusion relationships seem to have been a factor in a few cases. Our data clearly show that the diffusion was not implicated in the gas transfer defect. The clinical implications of this little studied and less mentioned respiratory defect are discussed. Since the defect may enhance the risk of sickling crises, it should be measured in each individual patient, for appropriate prophylactic measures. After accidents, pre and post-operatively and during acute respiratory illness, the defect should be again reevaluated. In all probability many patients will be discovered who represent a respiratory risk, and may require special immunizations, prophylactic antibiotics, professional relocation and, during emergencies, intensive respiratory care.
