Embeddings of circulant networks

In this paper we solve the edge isoperimetric problem for circulant networks and consider the problem of embedding circulant networks into various graphs such as arbitrary trees, cycles, certain multicyclic graphs and ladders to yield the minimum wirelength.     

The Role of Physical Context,Verbal Skills,Non‐parental Care,Social Support,and Type of Parental Discipline in the Development of ToM Capacity in Five‐Year‐Old Children

The aim of this study was to analyze the influence of family context on the performance of 5‐year‐old children (N = 70) in theory of mind (ToM) tasks. The children's performances were assessed during individual sessions held at school. Children's verbal skills were assessed using the Peabody picture vocabulary test (PPVT). Interviews were also conducted with parents in the family home in order to gather sociodemographic data and to assess diverse variables of the family context. In addition to confirming the important role played by children's verbal skills in ToM, the results also supported a potential influence of family context in ToM development through variables, such as quality of non‐parental care or level of social contact and support. The educational implications of these results are discussed in relation to family intervention.     

Translational research: implications for the study of work and family

ABSTRACT

Translational research facilitates the application of knowledge gained from research, bridging the divide between research and practice. In the context of work and family studies, translational research can take a variety of forms, depending upon the degree of engagement with stakeholders or end-users of the research. In this study, we defined and examined indicators of translational research in exemplary work and family research publications, in an effort to shed light on the adaptation of translational research perspectives to the work and family field. Using content analysis, we examined indicators of translational research in the 46 articles nominated for the 2018 Rosabeth Moss Kanter Award for work and family research. Of the 46 articles in the study, 24 (52.2%) included content suggesting translational research. The most common indicators of translational research involved presenting practical and policy applications or implications of research findings, while fewer articles mentioned developing sustained research-practice partnerships or engaging stakeholders in study design or implementation. We identify several implications of these findings for work and family scholars, academic organizations, professional associations, and the field of work and family research as a whole.     

Forced to deal with the future: uncertainty and risk in vocational choices among Portuguese secondary school students

In contemporary societies, adolescents' individuation is largely staged within the educational system, and is defined by several schooling options. This is particularly true when young people reach upper secondary education, as this transition implies the definition of a personal project. In the Portuguese context, authenticity is linked to the ‘obligation’ of choosing – by means of a compulsory vocational choice. To define a personal project that gives studies a meaning becomes a problem pupils have to deal with. Supported on empirical data based on in‐depth interviews to pupils attending 10th and 12th years of upper secondary education in Portuguese public schools, this article discusses some of these issues. Specially, we intend to explore pupils' obligation to exhibit their autonomy by choosing a school path with the awareness of risks that may emerge along with their options.     

On the potential in the estimation of linear functions in regression

New aspects of potential in Cook's Influence measure for linear combinations are explored. It is shown that this potential can be considered as a case influence measure in the scatter of estimated combinations. The potential is related to precise estimation directions and multicollinearity concepts; It Is also used as a basis for selection of new cases.     

Congruency of the Cognitive and Affective Components of the Attitude as a Moderator on Intention of Condom Use Predictors

Using data gathered through questionnaires on factors relating to the intention of condom use included in the Theory of Planned Behavior, we obtained evidence in favor of the two-dimensional structure of attitude: affective and cognitive components. In a structural equation model for predicting the intention of condom use as an instrumental behavior, we found that the congruence between the affective and cognitive components moderates the influence of attitude, subjective norm and perceived behavioral control in the intention of condom use. Since most of the studies do not take into account this proposed interaction, they can only report a kind of main effects average. Moreover, the percentage of explained variance of intention is higher for those individuals with the same value for the two components (congruent group). Furthermore, we found that perceived behavioral control is the most determining factor and that the cognitive component of the attitude is a better predictor than the affective one. The results are discussed from the point of view of their implications for designing prevention programmes for sexually transmitted diseases.     

Is the trend to publish reviews and clinical trials related to the journal impact factor? Analysis in dentistry field

ABSTRACT

It is generally accepted that the Journal Impact Factor is a quality criterion. The objective was to determine the evolution along the period 2010–2016 of number of different types of papers, reviews and clinical trials, published by dental journals, as well as if they are related with the quartile occupied in the Journal Impact Factor 2017 ranking. To this end, ten journals per quartile belonging to the field Dentistry, Oral Surgery and Medicine in the 2017 Journal Citation Reports were randomly selected. For each journal and year, the total number of narrative reviews, systematic reviews (with and without meta-analysis), meta-analysis, clinical trials and randomized controlled trials were obtained from Pubmed. To achieve our goal, the slope of these variables over time was estimated using the least squares method, after which one-way analysis of variance of mean values was performed. In Dentistry, the journals of the top quartiles show a trend to publish increasing amounts of systematic reviews and meta-analysis, than the ones of the third and fourth quartile. On the other hand, globally, there was virtually no increase in narrative reviews, clinical trials and randomized controlled trial. Possible causes of this behavior are also discussed in this article.     

Multidimensional Assessment of Poverty Alleviation in a Developing Country: A Case Study on Economic Interventions

Donors increasingly expect international nongovernmental organizations (INGOs) to prove that the organizations' economic development interventions alleviate poverty. Currently, many INGOs search for new methods to meet this demand by focusing on the expectations of donors rather than those of beneficiaries. We analyze the benefit of qualitative, context‐specific methods and ask the question: What can an economic development intervention contribute to poverty alleviation from the perspective of the beneficiaries? In our case study, a negative economic valuation was not automatically a reason to evaluate the economic intervention as a failure. Assessment thus cannot be reduced to economic impacts. Also, qualitative approaches can add beneficiary‐oriented data in a context in which accountability mainly focuses on donors. This beneficiary orientation likely leads to better accountability negotiations with donors. Three hypotheses introduce these results.     

Emotional Intelligence as a Protective Factor Against Psychological Maltreatment in Dating Couples According to Age

Abstract

Psychological violence during dating is a current phenomenon of universal proportions. Initiatives are urgently required to deal with this reality, initiatives focused on anticipating the potentially violent dynamics. Various works of research have confirmed that emotional intelligence can be a protecting factor against violence in relationships. This paper analyses the relation between the capacity to exercise behavior patterns of psychological maltreatment within dating couples and the subjects’ emotional competences, as well as its relation to the subjects’ age. 1080 students of the University of Extremadura (Spain) participated in the study, aged between 17 and 23?years or more. The results show the presence of all the behavior patterns of psychological maltreatment analyzed, especially among the students aged 17–18?years. Similarly, the existence of significant correlations between all the manifestations of psychological violence and the emotional competences studied are confirmed, with a great variability in the results depending on the subjects’ age. Future studies are suggested focusing on training in emotional self-management skills as a protective agent against psychological violence in dating couples and as a healthy marital mechanism with no age limit.
