How nurse preceptors provide help to new nurses influences perceived relationship quality.

BACKGROUND: In many hospitals, newly-hired registered nurses (RNs) enter into preceptorships, where they are paired with more experienced nurse preceptors who are responsible for ensuring effective transition to practice. Although high-quality relationships between preceptors and newly-hired nurses facilitate nurses' learning and integration into their medical institutions, preceptors have little guidance for what tactics develop such relationships. OBJECTIVES: To investigate whether the type of help provided by preceptors (i.e., autonomous or dependent help) influences preceptees' evaluations of relationship quality and psychological safety with their preceptor. Furthermore, we investigate the role of instrumental support and emotional support as explanatory mechanisms. DESIGN/SETTINGS/PARTICIPANTS/METHODS: Convenience sampling was used to collect data via a cross-sectional survey of 217 in-patient RNs hired between June 2016 and May 2018 to a magnet hospital within the Southwestern United States. Recently hired nurses evaluated their preceptor's help-giving tendencies, and reported on their perceived support, relationship quality and feelings of psychological safety with their preceptor. RESULTS: Dependent help was positively related to instrumental support. Conversely, autonomous help was positively related to both relationship quality and psychological safety, and these relationships were partially mediated by perceived instrumental support and emotional support. CONCLUSION: Findings illustrate the multiple benefits of autonomous help for encouraging high-quality relationships between preceptors and preceptees. This study identifies autonomous help-giving as a useful tactic for nurse preceptors (or other organizational insiders, such as mentors or supervisors) to establish high-quality relationships with recently hired nurses.

Associations between dietary fatty acid patterns and cognitive function in the Hispanic Community Health Study/Study of Latinos.

Our objective was to quantify the cross-sectional associations between dietary fatty acid (DFA) patterns and cognitive function among Hispanic/Latino adults. This study included data from 8,942 participants of the Hispanic Community Health Study/Study of Latinos, a population-based cohort study (weighted age 56.2 y and proportion female 55.2%). The NCI (National Cancer Institute) method was used to estimate dietary intake from two 24-hr recalls. We derived DFA patterns using principal components analysis with 26 fatty acid and total plant and animal monounsaturated fatty acid (MUFA) input variables. Global cognitive function was calculated as the average z-score of 4 neurocognitive tests. Survey linear regression models included multiple potential confounders such as age, sex, education, depressive symptoms, physical activity, energy intake, and cardiovascular disease. DFA patterns were characterized by consumption of long-chain saturated fatty acids (SFA), animal-based MUFA, and trans fatty acids (Factor 1); short to medium-chain SFA (Factor 2); very-long-chain omega-3 polyunsaturated fatty acids (PUFA) (Factor 3); very-long-chain SFA and plant-based MUFA and PUFA (Factor 4). Factor 2 was associated with greater scores for global cognitive function (ß=0.037 ± 0.012) and the Digit Symbol Substitution (DSS) (ß=0.56±0.17), Brief Spanish English Verbal Learning-Sum (B-SEVLT) (ß=0.23 ± 0.11), and B-SEVLT-Recall (ß=0.11 ± 0.05) tests (P<0.05 for all). Factors 1 (ß=0.04 ± 0.01) and 4 (ß=0.70 ± 0.18) were associated with the DSS test (P<0.05 for all). Consumption of short to medium-chain SFA may be associated with higher cognitive function among U.S.-residing Hispanic/Latino adults. Prospective studies are necessary to confirm these findings.

Building effective networks for the transition from the military to the civilian workforce: Who, what, when, and how.

Servicemembers leaving the military and entering the civilian workforce are often encouraged to network to identify and obtain civilian employment. However, there are few resources that offer insights into how to build an effective network when transitioning from the military to the civilian workforce. Based on extant literature, we present a Guiding Framework for Building an Effective Network for the Military to Civilian Workforce Transition to answer questions of who Veterans should include in their professional and personal networks ("Who"), what social resources are available from network contacts ("What") at which phase of the transition ("When"), and how to build relationships with network contacts that may facilitate the transition from the military to civilian workforce ("How"). This framework identifies four types of network contacts that Veterans may include in their networks: family members, other Veterans, civilians, and formal resources persons. Furthermore, we describe the social resources they are likely to receive from these contacts (e.g., love/friendship, information, services, status, money, and goods) at each stage of the transition (e.g. approaching the transition, managing the transition, and assessing the transition) as well as practical suggestions for Veterans to connect with these network contacts. Additionally, we explain how the resources provided by network contacts enable successful role/identity transition. Finally, we discuss practical implications of our framework for service members, and we propose directions for future research on Veterans' networks and the role that they play during Veterans' transition from the military to the civilian workforce.

How do instrumental and expressive network positions relate to turnover? A meta-analytic investigation.

Although social network methods have proven valuable for predicting employee turnover, an informed use of network methods for turnover management requires an integration and extension of extant networks-turnover research. To that end, this article addresses two relatively neglected issues in the networks-turnover literature: the lack of integration of turnover process models into networks-turnover research and the differential influence of "network content" (i.e., instrumental vs. expressive network resources) on turnover processes. To address these issues, we draw from social capital and turnover theories as a basis for investigating how turnover antecedents (i.e., work attitudes, job alternatives, and job performance) mediate the associations between instrumental and expressive degree centrality and turnover. We test a theoretical model using meta-analytic path analysis based on the results of random-effects meta-analyses (64 independent samples of working adults) of instrumental and expressive degree centrality in relation to job satisfaction, organizational commitment, job alternatives, job performance, and employee turnover. We found that both instrumental and expressive degree centrality relate to employee turnover, but through different mediating processes; instrumental degree centrality decreased the likelihood of turnover via job performance and organizational commitment, whereas expressive degree centrality decreased the likelihood of turnover via job satisfaction and organizational commitment. Furthermore, expressive degree centrality (as compared to instrumental degree centrality) had a negative association with turnover after accounting for these prominent turnover antecedents. These findings illustrate the importance of distinguishing between instrumental and expressive network positions in the turnover process as well as the value of leveraging employee networks for employee retention.

On-the-job and off-the-job embeddedness differentially influence relationships between informal job search and turnover.

Whereas informal job search (i.e., using personal contacts for job search) is positively associated with the receipt of job offers, research has yet to consider the extent to which informal job search translates into current employees' turnover decisions or to investigate factors that may restrain (or facilitate) the translation of informal job search into turnover decisions. In this study, we propose that on-the-job and off-the-job embeddedness play distinct roles in strengthening or weakening the positive relationship between informal job search and turnover intentions and behavior. We assert that on-the-job embeddedness reduces the likelihood that informal job search translates into turnover decisions, whereas off-the-job embeddedness strengthens the positive association between informal job search and turnover decisions. We tested these hypotheses across two samples of employed nurses. Although results were mixed, we found evidence that on-the-job embeddedness dampened the positive relationships of informal job search with turnover intentions and behaviors, whereas off-the-job embeddedness facilitated the positive relationships between informal job search and turnover decisions. Taken together, findings suggest that on-the-job and off-the-job embeddedness influence informal job search processes differently. We discuss the implications of these findings for how organizations manage employees' informal job search activities as well as how researchers approach the study of job embeddedness.

Cultural and Intellectual Openness Differentially Relate to Social Judgments of Potential Work Partners.

OBJECTIVE: This study investigates the differential functioning of cultural and intellectual openness (the two aspects of Openness to Experience) in relation to social cognitive processes by examining how they influence people's perceptions and interpretations of social information when deciding to initiate working relationships. METHOD: Using a policy-capturing design, 681 adult participants were asked to rate their similarity to and preference to work with potential work partners characterized by varying nationalities and levels of work-related competence. Multilevel moderated mediation was conducted to simultaneously evaluate whether the indirect effects of potential work partners' characteristics (i.e., nationalities and levels of work-related competence) on work partner preference through perceived similarity were moderated by cultural and intellectual openness. RESULTS: Perceived similarity mediated the relationships between work partner nationality and work-related competence and participants' work partner preferences. Furthermore, the negative indirect effect of work partner nationality on work partner preference via perceived similarity was attenuated by cultural openness, and the positive indirect effect of work partner work-related competence on work partner preference via perceived similarity was strengthened by intellectual openness. CONCLUSIONS: Cultural and intellectual openness may have distinct functions that influence how people perceive, evaluate, and appreciate social information when making social judgments.

Dietary sphingomyelin attenuates hepatic steatosis and adipose tissue inflammation in high-fat-diet-induced obese mice.

Western-type diets can induce obesity and related conditions such as dyslipidemia, insulin resistance and hepatic steatosis. We evaluated the effects of milk sphingomyelin (SM) and egg SM on diet-induced obesity, the development of hepatic steatosis and adipose inflammation in C57BL/6J mice fed a high-fat, cholesterol-enriched diet for 10 weeks. Mice were fed a low-fat diet (10% kcal from fat) (n=10), a high-fat diet (60% kcal from fat) (HFD, n=14) or a high-fat diet modified to contain either 0.1% (w/w) milk SM (n=14) or 0.1% (w/w) egg SM (n=14). After 10 weeks, egg SM ameliorated weight gain, hypercholesterolemia and hyperglycemia induced by HFD. Both egg SM and milk SM attenuated hepatic steatosis development, with significantly lower hepatic triglycerides (TGs) and cholesterol relative to HFD. This reduction in hepatic steatosis was stronger with egg SM supplementation relative to milk SM. Reductions in hepatic TGs observed with dietary SM were associated with lower hepatic mRNA expression of PPARγ-related genes: Scd1 and Pparg2 in both SM groups, and Cd36 and Fabp4 with egg SM. Egg SM and, to a lesser extent, milk SM reduced inflammation and markers of macrophage infiltration in adipose tissue. Egg SM also reduced skeletal muscle TG content compared to HFD. Overall, the current study provides evidence of dietary SM improving metabolic complications associated with diet-induced obesity in mice. Further research is warranted to understand the differences in bioactivity observed between egg and milk SM.

Milk sphingomyelin improves lipid metabolism and alters gut microbiota in high fat diet-fed mice.

High dietary fat intake can cause elevated serum and hepatic lipids, as well as contribute to gut dysbiosis, intestinal barrier dysfunction and increased circulating lipopolysaccharide (LPS). Dietary milk sphingomyelin (SM) has been shown to inhibit lipid absorption in rodents. We evaluated the effects of milk SM on lipid metabolism and LPS levels in C57BL/6J mice fed a high-fat diet for 4weeks and compared it with egg SM. Mice were fed a high-fat diet (45%kcal from fat) (CTL, n=10) or the same diet modified to contain 0.25% (wt/wt) milk SM (MSM, n=10) or 0.25% (wt/wt) egg SM (ESM, n=10). After 4weeks, MSM had gained significantly less weight and had reduced serum cholesterol compared to CTL. ESM had increases in serum cholesterol, triglycerides, phospholipids and SM compared to CTL. MSM significantly decreased, while ESM increased, hepatic triglycerides. This may have been related to induction of hepatic stearoyl-CoA desaturase-1 mRNA observed in ESM. MSM displayed intestinal and hepatic gene expression changes consistent with cholesterol depletion. MSM had significantly lower serum LPS compared to CTL, which may have been due to altered distal gut microbiota. Fecal Gram-negative bacteria were significantly lower, while fecal Bifidobacterium were higher, in MSM. These results suggest that milk SM is more effective than egg SM at combating the detrimental effects of a high-fat diet in mice. Additionally, distal gut microbiota is altered with milk SM and this may have contributed to the lower serum LPS observed.

Black elderberry extract attenuates inflammation and metabolic dysfunction in diet-induced obese mice.

Dietary anthocyanins have been shown to reduce inflammation in animal models and may ameliorate obesity-related complications. Black elderberry is one of the richest sources of anthocyanins. We investigated the metabolic effects of anthocyanin-rich black elderberry extract (BEE) in a diet-induced obese C57BL/6J mouse model. Mice were fed either a low-fat diet (n 8), high-fat lard-based diet (HFD; n 16), HFD+0·25 % (w/w) BEE (0·25 %-BEE; n 16) or HFD+1·25 % BEE (1·25 %-BEE; n 16) for 16 weeks. The 0·25 % BEE (0·034 % anthocyanin, w/w) and 1·25 % BEE (0·17 % anthocyanin, w/w) diets corresponded to estimated anthocyanin doses of 20-40 mg and 100-200 mg per kg of body weight, respectively. After 16 weeks, both BEE groups had significantly lower liver weights, serum TAG, homoeostasis model assessment and serum monocyte chemoattractant protein-1 compared with HFD. The 0·25 %-BEE also had lower serum insulin and TNFα compared with HFD. Hepatic fatty acid synthase mRNA was lower in both BEE groups, whereas PPARγ2 mRNA and liver cholesterol were lower in 1·25 %-BEE, suggesting decreased hepatic lipid synthesis. Higher adipose PPARγ mRNA, transforming growth factor ß mRNA and adipose tissue histology suggested a pro-fibrogenic phenotype that was less inflammatory in 1·25 %-BEE. Skeletal muscle mRNA expression of the myokine IL-6 was higher in 0·25 %-BEE relative to HFD. These results suggest that BEE may have improved some metabolic disturbances present in this mouse model of obesity by lowering serum TAG, inflammatory markers and insulin resistance.
