Impact of operator experience on information feedback and reusability

Keeping a record of operator experience remains a challenge to operation management and a major source of inefficiency in information management. The objective is to develop a framework that enables an explicit presentation of experience based on information use. A purposive sampling method is used to select four small and medium-sized enterprises as case studies. The unit of analysis is the production process in the machine shop. Data collection is by structured interview, observation and documentation. A comparative case analysis is applied. The findings suggest experience is an accumulation of tacit information feedback, which can be made explicit in information use interoperatability matrix. The matrix is conditioned upon information use typology, which is strategic in waste reduction. The limitations include difficulty of participant anonymity where the organisation nominates a participant. Areas for further research include application of the concepts to knowledge management and shop floor resource management.     

A Weighted Multidimensional Index of Child Well-Being Which Incorporates Children’s Individual Perceptions

It has been a decade since a landmark piece of work on child well-being measurement based on a summary index was developed in the United States, the Index of Child and Youth Well-Being. Several research studies, both in the U.S. and Europe, followed on from this work. Despite these studies’ valuable contribution, scope exists for further improvements at the methodological level. In the present paper we draw the methodological basis for a new, micro-based summary child well-being index in which children’s views on their own well-being assume a central role and distinct weights (based on the children’s perceptions) to each component that is included in the index are used. Based on 914 pairs of responses of Portuguese children and their carers, the newly proposed index was tested vis-à-vis other methodologies. The econometric estimations show that the significance of all potential well-being determinants (e.g., age, school cycle, mother’s and father’s level of education) remains the same across the distinct methods of calculation of child well-being indexes. However, the consideration of subjective components (degrees of importance and weights) allowed to evidence that the most relevant determinants of child well-being are the set of variables related to the child’s parents, namely education and professional status. In particular, when compared to their counterparts, children whose fathers have higher education degrees reveal an increased overall well-being by around 25 %, whereas children whose fathers are unemployed present a decreased well-being by around 11 %.     

Physical Activity, Depression and Anxiety Among the Elderly

The aim of this study was to compare by sex, physical activity, and academic qualifications the symptomatology of depression among elders. The sample consisted of 140 elderly, 70 elements were male and 70 female, aged over 62 years. The instruments used to assess the dependent variables were the Scale of Moderate to Vigorous Physical Activity, the Beck Depressive Inventory and the State-Trait Anxiety Inventory. Significant gender effects were obtained demonstrating that those who practiced physical activity had lower rates of depression and anxiety. Comparisons showed that women had higher values than men. At the level of educational attainment it was found that individuals with lower level of education tended to have higher values for both depression and anxiety. Finally, a significant correlation was identified between physical activity, depression and anxiety, and for trait anxiety, however this correlation was not statistically significant. It was concluded that physical activity is associated with lower levels of depression and anxiety.     

Prevalence of Metabolic Syndrome and Individual Criteria in College Students

Abstract

Metabolic syndrome (MetS) is present in young adults and because coronary heart disease (CHD) is likely, screening to determine MetS prevalence and its criteria is critical. Objective: To determine MetS prevalence and most prevalent criteria in a sample of first-year college students. Participants: First-year college students between 18 and 24 years of age (n = 189). Methods: Metabolic syndrome was defined using the updated 2001 National Cholesterol Education Programs Adult Treatment Panel III. Anthropometrics and blood pressure were obtained. Lipid and glucose concentrations were determined. Results: Overall prevalence of MetS was 3.7%. Prevalence of 1 or 2 MetS criteria was 28.0% and 7.4%, respectively. Low high-density lipoprotein cholesterol (20.1%) and elevated triacylglycerol (17.5%) concentrations were the most prevalent criteria. Conclusions: Young adults have and are at risk of developing MetS. Identification of MetS early in life is critical and screening young adults will aid in targeted intervention development to decrease CHD risk.     

The moderating effect of personal values in the relationship between working conditions and wellbeing / El efecto moderador de los valores personales en la relación entre condiciones de trabajo y bienestar

Abstract

The main objective of this study was to evaluate the impact that the opportunities to realize personal values at work have on wellbeing. More specifically, we tried to test the moderating effect of personal values on the relationship between opportunities for fulfilment and wellbeing. A sample of 403 civil servants from a public institution in Brazil answered a questionnaire that included measures for each of the variables studied. The results from hierarchical regression showed that there were no significant interactions between opportunities to realize personal values at work and personal value priorities in the prediction of wellbeing at work. The mere presence of opportunities to realize values that express individual interests is enough to increase wellbeing. Likewise, the results converge with those of other previous studies on the importance of working conditions in predicting wellbeing. On the other hand, this study included variables that up to now have not been used in the field of wellbeing at work, especially in relation to its eudaimonic and hedonic elements.     

Super PACs and Strong Relationships: The Impact of Digital Interaction on the Political Organization–Public Relationship

Contributing to the development of digital political public relations scholarship, this study examines the political organization–public relationship cultivated via social media. Using Twitter as a vehicle, this posttest-only experimental design looked at whether interaction with a political organization facilitated a relationship. Furthermore, the study examined whether that relationship might manifest into political support. Results indicate active engagement (tweeting at an organization), even for a short term, increases the sense that there is a real conversational exchange, enhancing the organization–public relationship. Internal political disposition such as political cynicism, political information efficacy, or strength of ideology in some cases can help predict organization–public relationship.     

Nonresident Fathers' Contributions to Adolescent Well-Being

Using data from 453 adolescents in Wave 2 of the National Survey of Families and Households, we examine how multiple dimensions of nonresident father involvement are associated with different dimensions of child well-being. Father-child relationship quality and responsive fathering are modestly associated with fewer externalizing and internalizing problems among adolescents. The quality of the mother-child relationship, however, has stronger effects on child well-being. Nevertheless, even if adolescents have weak ties to mothers, those who have strong ties to nonresident fathers exhibit fewer internalizing problems and less acting out at school than adolescents who have weak ties to both parents. Adolescents are worst off on a range of outcomes when they have weak ties to both their mothers and nonresident fathers.     

Brazilian housemaids and COVID‐19: How can they isolate if domestic work stems from racism?

This article proposes a debate about the situation of Brazilian housemaids in the context of the COVID‐19 pandemic to expand the discussion on this scenario and link it structurally to racism and the history of colonialism, from the perspective of its successful project of establishing racial inequalities and relegating Black women to the most vulnerable conditions. As staying at home is not a choice for these women, the suppression of the right to life reflects how the necropolitics against Black Brazilians operates. In Brazil, the naturalization of this form of violence finds great support in a mixture of affection and inequality relationships, in a context in which domestic workers, specifically housemaids, figure as the memory of Black mothers, that is, the enslaved women of the colonial period, coming from the African diaspora. This memory is associated with the whiteness naturalization of the subordinate status of Black women.     

Heteroskedasticity-Robust Inference in Linear Regressions

The assumption that all errors share the same variance (homoskedasticity) is commonly violated in empirical analyses carried out using the linear regression model. A widely adopted modeling strategy is to perform point estimation by ordinary least squares and then perform testing inference based on these point estimators and heteroskedasticity-consistent standard errors. These tests, however, tend to be size-distorted when the sample size is small and the data contain atypical observations. Furno (1996 Furno , M. ( 1996 ). Small sample behavior of a robust heteroskedasticity consistent covariance matrix estimator . Journal of Statistical Computation and Simulation 54 : 115 – 128 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) suggested performing point estimation using a weighted least squares mechanism in order to attenuate the effect of leverage points on the associated inference. In this article, we follow up on her proposal and define heteroskedasticity-consistent covariance matrix estimators based on residuals obtained using robust estimation methods. We report Monte Carlo simulation results (size and power) on the finite sample performance of different heteroskedasticity-robust tests. Overall, the results favor inference based on HC0 tests constructed using robust residuals.
