On the role of Prognostics and Health Management in advanced maintenance systems

The advanced use of the Information and Communication Technologies is evolving the way that systems are managed and maintained. A great number of techniques and methods have emerged in the light of these advances allowing to have an accurate and knowledge about the systems’ condition evolution and remaining useful life. The advances are recognised as outcomes of an innovative discipline, nowadays discussed under the term of Prognostics and Health Management (PHM). In order to analyse how maintenance will change using PHM, a conceptual model is proposed built upon three views. The model highlights: (i) how PHM may impact the definition of maintenance policies; (ii) how PHM fits within the condition-based maintenance; and (iii) how PHM can be integrated into reliability-centred maintenance programmes. The conceptual model is the research finding of this review note and helps to discuss the role of PHM in advanced maintenance systems.     

Failure to Realize Fertility Intentions: A Key Aspect of the Post-communist Fertility Transition

Our paper focuses on the realization of fertility intentions, exploring a new aspect of the post-communist fertility transition. By making use of a follow-up study, it was possible to compare five European countries and to analyze the chances of realizing short-term, time-dependent fertility intentions. There is always a difference between intention and behavior. It is partly due to demographic and social factors, such as age, parity, partnership status, but once these are accounted for, important differences remain between western European and post-communist countries. In the period after the turn of the millennium, chances of realizing intentions are significantly lower in post-communist countries than in western European countries. The lower chance of realization is a consequence of social anomie originating from discrepancy between slow value shift and the increased dynamism of structural changes.     

Bourdieu,ethics and symbolic power

This article critically discusses Pierre Bourdieu's views on ethics and normative evaluations. Bourdieu acknowledged that people hold ethical stances, yet sought to show that these stances are – unconsciously – conducive to obtaining symbolic power and legitimizing hierarchy. The first part of the article looks at this argument and charts the shifts it went through particularly in the early 1990s. The second part discusses ontological and empirical critiques of the ethics as ideology argument and suggests the latter to be more salient, as Bourdieu proposed his argument as an empirical rather than as an ontological point. The reason why he nevertheless found the ethics as ideology explanation fitting to nearly all the cases he studied, as the third part argues, is not simply that reality ‘obliged’ him to do so, but his circular definition of symbolic capital as qualities that are worthy of esteem. This definition makes his argument of ethics as ideology unfalsifiable and impedes him from distinguishing between cases when legitimate power is the aim of ethics and between those when it is merely their side effect. The article concludes by suggesting ways in which Bourdieu's work can be fruitfully incorporated into the study of ethics once the tautology is resolved.     

May the force be with you: Looking for resources that build team resilience

The aim of this study is to analyze team resilience as a collective psychosocial construct in the framework of the conservation of resources theory. Specifically, the authors hypothesize that (a) team-level resources and (b) organizational-level healthy practices would be positively related to team resilience. Multilevel regression modeling was conducted, using data from 1,167 employees nested in 194 work teams (team level) from 38 organizations (organizational level). Results confirmed the hypotheses having team-level resources and organizational-level healthy practices significant relationships with team resilience. This study provides evidence that team and organizational resources have a strong relationship with team resilience. Practitioners and managers must take these results into account for planning how to manage their resources within the organization. This article found what resources are required (at the team and the organizational level) to help work-team resilience.     

Dating violence in young Mexican couples: a dyadic analysis / Agresiones en el noviazgo de universitarios mexicanos: un análisis diádico

This study analyses the frequency, perception, bidirectionality and degree of agreement in the occurrence of aggression committed and suffered in 100 heterosexual couples. The selection of the sample was non-probabilistic, with 100 Mexican male-and-female dyads (age range 18 to 25). We used a virtual questionnaire which evaluated the frequency of psychological, mild physical and sexual aggression committed and suffered by each member of the dyads. Psychological aggression was the most frequent, and no significant differences were found by sex except in sexual aggression committed by men. The women more often underestimated both the aggression they suffered from and that which they committed, primarily sexual aggression. Bidirectionality was found in all three kinds of aggression, and there was greater agreement between couples when the women were the aggressors than when the men were the perpetrators. More studies are needed on couple violence that include the perspective of both members of the dyad.     

Perceived Similarity With Gay Men Mediates the Effect of Antifemininity on Heterosexual Men’s Antigay Prejudice

This research examined the hypothesis that heterosexual men’s motivation to differentiate themselves from gay men mediates the relationship between the antifemininity norm of masculinity and antigay prejudice. We assessed masculinity through three concepts: status, thoughness, and antifemininity. Participants then reported their perceived similarity with gay men and their antigay prejudice. The results showed that antifemininity was the best predictor of both perceived similarity and antigay prejudice: The more people endorsed the antifemininity norm, the more they perceived themselves as dissimilar from gay men and showed antigay prejudice. More important, perceived similarity mediated the effect of antifemininity on antigay prejudice. These findings provide direct evidence for the link between masculinity and the motivation to differentiate oneself from gay men, and they suggest that antigay prejudice accomplishes the identity function of maintaining unambiguous gender boundaries.     

Challenges for Divorced Parents: Regulating Negative Emotions in Post‐Divorce Relationships

Emotion regulation processes in post‐divorce parental relationships are analysed using thematic qualitative analysis. In two separate interview episodes, three and five years post‐divorce, 55 people were interviewed: 10 couples and 35 individuals. Two themes emerged on how parents deal with their negative emotions after divorce. The first theme, emotion regulation flexibility, reveals how some parents effectively regulate negative emotions following the divorce. The second theme, emotion regulation rigidity, reveals that other parents retain feelings of anger, hostility, and resentment following the divorce as a consequence of dysfunctional emotion regulation strategies. This allows a deeper understanding of the processes of emotion regulation in family conflict, which may be easily applied in most therapeutic orientations.     

Incorporation of Migrant Students Returning From the United States to High Schools in Mexico

The purpose of this research was to identify the difficulties faced by the Mexican migrant students when incorporated into the Mexican education system after having studied in the United States of America. Thirty migrant middle school students, two principals, two social workers and one teacher participated in the study. The study (conducted in two phases) collected information regarding: school admission, adjustment to the school organization, adaptation to learning situations and the perception of school belonging. The main problems found during the admission and enrolment procedures in Mexican schools are: language use, diagnostic assessment, didactic processes that take place in the classroom, complementary support activities, grade repetition, very little family involvement and the separation of the students from their migrant parents.     

Measuring Socio-Demographic Differences in Volunteers with a Value-Based Index: Illustration in a Mega Event

The phenomenon of volunteering can be analysed as a consumer experience through the concept of value as a trade-off between benefits and costs. In event volunteering, both the expected value (pre-experienced) and the perceived value (post-experienced) of volunteering can be assessed. With this purpose, an online quantitative survey is conducted with a sample of 711 volunteers in a religious mega event, with questions related to five dimensions of their experience: efficiency, social value, play, spirituality and time spent. These five scales, properly tested are used for building a multidimensional index of both the expected and perceived value of the volunteer experience. ANOVAs test show significant differences on the index in both moments upon the socio-demographic profiles: negative expectations/experience balance by age, contrasted results by sex, and more experienced volunteers being more critical with the value experienced. Implications for event managers are proposed, in line with the motivation of volunteers.
