This study proposes and tests a new theoretical model explaining whether, and how, supervisors socialize "temporary newcomers," defined as new organizational members who join an organization on a temporary basis, with a potential, but uncertain, opportunity of receiving a long-term job offer in the future. We suggest that under specific conditions, supervisors first evaluate temporary newcomers' proactivity based on whether they positively stand out by proposing new feasible ideas and by promoting their achievements. On the basis of these initial evaluations, supervisors then decide whether to increase their support of newcomers' creativity (using an investiture approach) or to intensify newcomers' socialization by attempting to change their behavior (using a divestiture approach). When supervisors adopt an investiture approach, it positively influences temporary newcomers' socialization adjustment outcomes, as indicated by increased newcomer job satisfaction, social integration, task performance, organizational and task socialization, challenge stress, and reduced hindrance stress. When supervisors instead adopt a divestiture approach, it has an opposite (thus negative) effect on the same socialization outcomes. We tested our theoretical model using a mix-method design, based on a three-wave longitudinal sample of 325 newcomer–supervisor dyads spanning a wide range of companies and industries, complemented with interviews of 41 supervisors.

This study examines the extent to which perceptions of family‐friendly organisational culture relate to employees' satisfaction with work–family balance (SATWFB) and how this, in turn, associates with their turnover intentions (TIs). Furthermore, we explore the extent to which employee experiences of different levels of government effectiveness (GE; high, medium and low) moderate these associations. Drawing on the work–home resources (W‐HR) model, we test our hypotheses with a sample of 1185 employees drawn from countries with substantially different levels of GE—Nigeria, the Philippines, Guatemala and Spain. Our results show that employees' perceptions of SATWFB mediate the relationship between the two dimensions of family‐friendly organisational culture and TIs of employees. This mediation is weaker for countries where employees experience high GE. Our findings contribute to research on the drivers of work–family balance satisfaction from a cultural and organisational perspective. We expand this line of research by introducing a new resource: GE. Our focus on four different national contexts also strengthens the comparative work–family balance literature.

This paper introduces a novel method to assess the social activity maintained by psychiatric patients using information and communication technologies. In particular, we model the daily usage patterns of phone calls and social and communication apps using point processes. We propose a novel nonhomogeneous Poisson process model with periodic (circadian) intensity function using a truncated Fourier series expansion, which is inferred using a trust-region algorithm. We also extend the model using a mixture of periodic intensity functions to cope with the different daily patterns of a person. The analysis of the usage of phone calls and social and communication apps of a cohort of 259 patients reveals common patterns shared among patients with relatively high homogeneity and differences among patient pathologies.

Purpose – The purpose of this study was to examine how national context moderates the impact of family supportive supervisory behavior (FSSB) on employee’s job performance and turnover intentions. The authors consider direct and indirect (through work–family positive spillover) effects of FSSB. Our model is based on conservation of resources (COR) theory and boundary theory. The authors conceptualize national context as contributing resources to or threatening with loss of resources for individuals. To test the model, the authors use data from three Latin American countries – Brazil, Chile and Ecuador. Design/methodology/approach – This is a cross-sectional study based on a survey of almost 988 individuals. The authors first test the direct and indirect effects (via bi-directional positive spillover) of FSBB on performance and turnover intentions without considering the moderating effects of national context (mediation analysis). Then, the authors test the effect of national context in our baseline model by conducting a moderation analysis of direct and indirect effects. The authors use seemingly unrelated regressions and account for control variables and country-level effects. Findings – The results confirm that national context affects the relationships between FSSB and outcomes. As unemployment rises, the effect of FSSB on turnover intentions is stronger and the effect of FSSB on performance, via bi-directional work–family positive spillover, is stronger. When social expenditures increase, the relationship between FSSB and performance via work–family positive spillover becomes weaker. In addition, the authors find some unexpected results. Originality/value – The authors advance the understanding of how national context affects the impact of FSSB on outcomes, specifically in Latin America. The authors conceptualize national context as providing or threatening individuals’ resources, using publicly available data on unemployment and social expenditures. [ABSTRACT FROM AUTHOR] more...

The Scotogenic model is an economical scenario that generates neutrino masses at the 1-loop level and includes a dark matter candidate. This is achieved by means of an ad-hoc Z 2 symmetry, which forbids the tree-level generation of neutrino masses and stabilizes the lightest Z 2 -odd state. Neutrino masses are also suppressed by a quartic coupling, usually denoted by λ 5. While the smallness of this parameter is natural, it is not explained in the context of the Scotogenic model. We construct an ultraviolet completion of the Scotogenic model that provides a natural explanation for the smallness of the λ 5 parameter and induces the Z 2 parity as the low-energy remnant of a global U (1) symmetry at high energies. The low-energy spectrum contains, besides the usual Scotogenic states, a massive scalar and a massless Goldstone boson, hence leading to novel phenomenological predictions in flavor observables, dark matter physics and colliders.

Variability is defined as the propensity at which a given signal is likely to change. There are many choices for measuring variability, and it is not generally known which ones offer better properties. This paper compares different variability metrics applied to irregularly (nonuniformly) sampled time series, which have important clinical applications, particularly in mental healthcare. Using both synthetic and real patient data, we identify the most robust and interpretable variability measures out of a set 21 candidates. Some of these candidates are also proposed in this work based on the absolute slopes of the time series. An additional synthetic data experiment shows that when the complete time series is unknown, as it happens with real data, a non-negligible bias that favors normalized and/or metrics based on the raw observations of the series appears. Therefore, only the results of the synthetic experiments, which have access to the full series, should be used to draw conclusions. Accordingly, the median absolute deviation of the absolute value of the successive slopes of the data is the best way of measuring variability for this kind of time series.

Background: Cardiac magnetic resonance (CMR) is essential for diagnosing cardiomyopathy, serving as the gold standard for assessing heart chamber volumes and tissue characterization. Hemodynamic forces (HDF) analysis, a novel approach using standard cine CMR images, estimates energy exchange between the left ventricular (LV) wall and blood. While prior research has focused on peak or mean longitudinal HDF values, this study aims to investigate whether unsupervised clustering of HDF curves can identify clinically significant patterns and stratify cardiovascular risk in non-ischemic LV cardiomyopathy (NILVC)., Methods and Results: A retrospective cohort of 279 patients with NILVC who underwent cardiac CMR at Vall d'Hebron University Hospital (Barcelona) was examined. Unsupervised clustering of longitudinal and transversal HDF curves was performed using Dynamic Time Warping for dissimilarity measurement and the Partitioning Around Medoids algorithm. Outcomes were defined as a composite of cardiovascular mortality, heart failure hospitalization, and ventricular arrhythmias. Median age was 65[57.0;74.0] years, with 27.2% females and 35.5% showing late gadolinium enhancement (LGE). Unsupervised clustering identified three distinct clusters, delineating risk groups with worsening LA and LV function, indicating a stepwise increase in cardiovascular risk profile. Over a median follow-up of 40 months, 60 patients experienced the composite outcome. After adjusting for LGE, LVEF and LV size, clusters 2 and 3 demonstrated a significantly higher risk of adverse events (both p<0.05) compared to cluster 1., Conclusion: Analyzing both longitudinal and transversal HDF throughout the cardiac cycle enables the identification of distinct phenotypes with prognostic value beyond ejection fraction and LGE in NILVC patients., (© The Author(s) 2025.

Although cross-national work-family research has made great strides in recent decades, knowledge accumulation on the impact of culture on the work-family interface has been hampered by a limited geographical and cultural scope that has excluded countries where cultural expectations regarding work, family, and support may differ. We advance this literature by investigating work-family relationships in a broad range of cultures, including understudied regions of the world (i.e., Sub-Saharan Africa, Southern Asia). We focus on humane orientation (HO), an overlooked cultural dimension that is however central to the study of social support and higher in those regions. We explore its moderating effect on relationships between work and family social support, work-family conflict, and work-family positive spillover. Building on the congruence and compensation perspectives of fit theory, we test alternative hypotheses on a sample of 10,307 participants from 30 countries/territories. We find HO has mostly a compensatory role in the relationships between workplace support and work-to-family conflict. Specifically, supervisor and coworker supports were most strongly and negatively related to conflict in cultures in which support is most needed (i.e., lower HO cultures). Regarding positive spillover, HO has mostly an amplifying role. Coworker (but not supervisor) support was most strongly and positively related to work-to-family positive spillover in higher HO cultures, where providing social support at work is consistent with the societal practice of providing support to one another. Likewise, instrumental (but not emotional) family support was most strongly and positively related to family-to-work positive spillover in higher HO cultures.

This research focuses on the antecedents of family supportive supervisor behaviors (FSSB) - the support from supervisors that can help employees manage their competing demands across work and nonwork domains. Drawing on theories of relational identity and self-construal, I conceptualize subordinates' likeability (interpersonal abilities) and competence (task abilities) as antecedents of family supportive supervisor behaviors, and examine whether supervisors' relational identification with subordinates mediates this relationship. In addition, I also examine the extent to which this mediation depends on the level of relational self-construal of supervisors. Data from 205 subordinates and 84 supervisors from a Chilean private bank and results support the hypothesized mediated moderation model. While supervisors' relational identification with subordinates fully mediates the relationship between competence and family supportive supervisor behaviors, supervisors' relational identification with subordinates partially mediates the relationship between subordinates' likeability and family supportive supervisor behaviors. Further, supervisors' relational identification with subordinates mediates the relationship between likeability and family supportive supervisor behaviors when supervisors' relational self-construal is high to medium but not when it is low. Overall, this research offers a novel lens for better understanding subordinates as more than mere recipients of supervisory behaviors., Competing Interests: The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Escribano.) more...
