Objective: The study explores the psychometric properties of the Brazilian-Portuguese version of the Working Memory Rating Scale (WMRS-Br) in a population of 355 young children from diverse socioeconomic status and schooling backgrounds. Method: Public and private school teachers completed the WMRS-Br and children were assessed on a range of objective cognitive measures of fluid intelligence, working memory, and attention. Results: Reliability and validity of the WMRS-Br were excellent across the public and private school sample. The WMRS-Br manifested substantial links with objective measures of working memory and medium links with selective attention, switching, and interference suppression. Confirmatory factor analyses suggest that a shorter version of the scale provides an adequate fit to the data. Conclusion: The WMRS-Br represents a valid screening tool in a Latin American context that has the potential to improve the early detection of working memory deficits in children growing up in poverty.

This study explores the underlying factor structure of executive functions, working memory, and language in young children from a range of social backgrounds. A particular interest was to investigate the effect of socioeconomic status on the identified factor structure and to explore whether potential links might be mediated by stimulation in the home and/or nutritional status. A population of 400, six- and eight-year-olds, completed multiple measures of working memory, short-term memory, response inhibition, conflict resolution, focused attention, fluid intelligence, and language. Socioeconomic status was indexed by the education and occupation of the caregivers and household income. Anthropometrical assessments were conducted to establish nutritional status; Environmental stimulation was explored via interviews conducted with the caregivers. The results contribute to theoretical conceptions of the components of executive functions in childhood and their link with related cognitive systems. They also contribute to an increased understanding of the relationship between poverty and cognitive achievement. [less ▲]

The relationship between working memory, verbal short-term memory, phonological awareness, and developing language skills was explored longitudinally in children growing up in a multilingual society. A sample of 121 children from Luxembourg were followed from the end of Kindergarten to 1st Grade, and completed multiple assessments of verbal short-term memory, complex working memory, phonological awareness, native and foreign vocabulary knowledge, language comprehension, and reading. Results indicate that relations between the measures were best characterized by a model consisting of two related but separable constructs – corresponding to verbal short-term memory and the central executive – that were distinct from phonological awareness. The data further showed that assessments of verbal short-term memory in Kindergarten significantly predicted vocabulary knowledge and comprehension in native and foreign languages one year later: Central executive and verbal short-term memory measures in Kindergarten were significantly associated with reading in 1st Grade and phonological awareness, indexed by rhyme detection, did not predict any of the language constructs one year later. The findings lend strong support to the position that verbal short-term memory is one of the main contributors to new word learning in both native and non-native languages by supporting the formation of stable phonological representations of new words in long-term memory. Verbal short-term memory also seems to play a significant role in the syntactic comprehension of sentences. The heard material might be kept active in verbal short-term memory while the child is listening to the sentence and processing it for comprehension. Finally working memory appears to make significant contributions to reading development. One explanation of these findings is that literacy classroom activities often impose heavy demands on working memory, the capacity of which therefore has a direct effect on the frequency of task failure or success in these classroom activities which consequently influences the rate of learning.

This study investigated the relationship between working memory, phonological processing and developing language skills in a population of children growing up in a multilingual context involving the three languages of Luxembourgish, German, and French. A sample of 122 children from Luxembourg, aged between 5 and 7 years, participated in the study, and completed assessments of phonological short-term memory, complex working memory, phonological awareness, native and foreign vocabulary knowledge, language comprehension and reading. The data were best characterized by a measurement model in which working memory consists of two related yet distinct components – corresponding to phonological short-term memory and a central executive – that were distinct from phonological awareness. Language abilities in both the native and foreign languages were more strongly associated with phonological short-term memory than other constructs in the model. The findings lend strong support to the proposal that vocabulary learning in particular is mediated in part at least by the phonological loop component of working memory. [less ▲]

Underemployment and overemployment are widespread in developed countries and have detrimental consequences on health. This article tackles the question of the relationship between health and own, spousal and cross working time mismatches in bi-active couples. Using 83,000 observations from the German SOEP (1997–2012) I demonstrate that self-assessed health is reduced in case of overemployment and underemployment. I find that living with an overemployed partner is negatively correlated with own health. However, I show that the effect of overemployment is lower for those who live with an overemployed partner. This positive cross-effect is consistent with the existence of a comparison norm effect within household. Those results are robust to a battery of sensitivity checks and mostly transit via mental health. This article concludes that overemployment does not only affect the overemployed workers but also their partner and not accounting for such spillovers leads to an underestimation of the total health costs of overemployment.

In this response paper, we reflect upon the contributions of Gallard Martínez, Pitts, Brkich, and Ramos de Robles (this issue) in their manuscript “How does one recognize contextual mitigating factors (CMFs) as a basis to understand and arrive at better approaches to research designs” and elaborate the ways in which we work toward highlighting the contextual complexities within our own research. Our research focuses on working toward equitable practices for culturally and linguistically diverse children in science education, in order to draw on the many cultural and communicative resources they bring to primary school science investigations. We draw upon our previous and current research projects in this forum contribution to tease-apart CMFs related to issues of equity in teaching science with culturally and linguistically diverse primary school children in our national context in Luxembourg. We conclude with a consideration of how the process of unpacking a diverse array of CMFs relative to our work with students helps us select and employ theoretical lenses and research methodologies that position us to gather rich understandings of the complexities within our research contexts and in our work with children and teachers [less ▲]

Datasets with missing values are very common in industry applications. Missing data typically have a negative impact on machine learning models. With the rise of generative models in deep learning, recent studies proposed solutions to the problem of imputing missing values based various deep generative models. Previous experiments with Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs) showed promising results in this domain. Initially, these results focused on imputation in image data, e.g. filling missing patches in images. Recent proposals addressed missing values in tabular data. For these data, the case for deep generative models seems to be less clear. In the process of providing a fair comparison of proposed methods, we uncover several issues when assessing the status quo: the use of under-specified and ambiguous dataset names, the large range of parameters and hyper-parameters to tune for each method, and the use of different metrics and evaluation methods.

Using critical ethnography guided by cultural sociology, this manuscript examines the role of “co” in teacher education; coresearching, coteaching, and cogenerating dialogue. The authors are a pre-service teacher and college instructor, and through our multiple perspectives and positionings we explore how collaboration served to dismantle teacher-student hierarchies and replaced them with complex relationships mediated by polysemic approaches to research. Pushing against traditional ideologies, we utilize a multi-voiced approach to writing as we present our experiences and interpretations of data relative to the possibilities of collaboration in education and research. As we analyze our role in collaborative endeavors, we ask: How can we find ways to work across and around hierarchical institutional structures when working with our students? What are ways that we can examine our individual lived experiences together, and is it possible to work with each other to develop identities as teachers that are not predicated on power differentials?

This research aims to gain a better understanding of the attachment of teachers to their workplace by identifying the areas to which they become attached and which give meaning to their work. Based on the belief that place attachment is an affective bond between a person and his or her environment (Bonnes & Secchiaroli, 1995), its aim is to identify the attachment of secondary school teachers to their workplace, which is viewed as a whole but also as a combination of specific places, and to show that the places that predict overall workplace attachment are also those that give meaning to work. A Workplace Attachment Scale was completed by 158 teachers in a secondary school in the Paris region (France). This questionnaire contained items evaluating attachment to each specific place of work and others adapted from the meaning-of-work scale evaluating the meaning given to each of these places. The results show that all the teachers were more closely attached to places that provide opportunities for informal communication than to those directly related to teaching. The main workplace attachment predictors also concern places constituting the essence of the profession and/or places where teachers can manage their organizational stress. [less ▲]

The aim of this paper is to clarify the relationship between psycho-environmental variables and work satisfaction by comparing them in a single model of psycho-organizational variables whose impact on satisfaction at work is well known. One hundred and twelve French supermarket workers completed a questionnaire composed of indicators assessing: (a) job satisfaction (ESVP and M.S.Q), (b) psycho-environmental variables (EALT, A-E scale, and a questionnaire about workspace appropriation and workplace attachment), and (c) psycho-organizational variables using some of Karasec’s control scales, Geurts’ SWING, and Meyer, Allen, and Smith’s organizational commitment scale. Regression analysis showed that the psycho-environmental variables were predictors of job satisfaction, some being more relevant predictors of the MSQ and particularly of the ESVP than the psycho-organizational variables. These results contribute to the current debate on the operationalization of the concept of job satisfaction. [less ▲]

Workplace bullying is a serious phenomenon that has serious detrimental effects on victim’s health, attitudes, and work-related behavior. Drawing on self-determination theory, we propose that bullying exposure thwarts employee’s need for relatedness with the result of decreased well-being. Studies examining these mechanisms used either a cross-sectional design (Trépanier et al., 2013) or a longitudinal design with (not theoretically justified) long time intervals (i.e., 12-month time lag; Trépanier et al., 2015). Therefore, the aim of our study was to test this mediation in a longitudinal design with much shorter time intervals (i.e. monthly), whether to see if the bullying exposure also shows short-term effects on well-being. A six-wave online survey design with monthly time lag was employed and data were collected among U.S. employees. The sample consists of 1,595 respondents (55.8% females, n=890, ageM = 36.9, ageSD =10.3). Workplace bullying exposure was assessed with the S-NAQ (Notelaers et al., 2018), frustration of the need for relatedness with the Psychological Needs Thwarting Scale (Bartholomew et al., 2011) and well-being with the WHO-5 well-being-index (Topp et al., 2015). Cross-lagged mediation analysis within a structural equation modeling framework confirmed the mediation model: Bullying exposure was significantly related to a change in frustration of relatedness and frustration of relatedness was significantly related to a change in well-being across all waves. The study findings advance the field through showing that bullying exposure has not only a long-term effect on well-being but also a short one, and that this effect is mediated through the frustration of relatedness.

Workplace bullying, mobbing or harassment describe a situation where an employee is the target of systematic mistreatment by other organizational members (i.e., colleagues, supervisors, subordinates) that may cause severe social, psychological and psychosomatic problems in the targeted employee. Since the appearance of the book “The harassed worker” by Brodsky (1976) and initial studies by Heinz Leymann (1986, 1990), workplace bullying research has developed into a huge and still massively growing research area that is conducted all over the globe. Especially, when related concepts are considered, a vast amount of studies have researched prevalence, risk factors, consequences, and, very recently, psychological mechanisms of workplace bullying exposure. A literature review revealed that existing workplace bullying exposure self-report inventories exhibit some weaknesses. Therefore, the first study (Chapter 2) aimed to develop a new short scale, the Luxembourg Workplace Mobbing Scale (LWMS) in three different language versions (i.e., Luxembourgish, French, German). Furthermore, it investigated the psychometric properties and the validity of this scale and examined if the three language versions exhibit measurement invariance. The LWMS revealed good psychometric properties in terms of its internal consistency and its factor structure. Furthermore, metric and partial scalar invariance across the three language versions could be established. Initial validation tests revealed high criterion validity of the LWMS. In line with recent workplace bullying exposure research, the LWMS was meaningfully linked with other working factors and measures of psychological health. The second study (Chapter 3) aimed to test the LWMS’s factor structure and measurement invariance across possible risk groups of bullying exposure (i.e., gender, age, and occupational groups). Moreover, based on recent theories and findings on workplace bullying the study aimed to further elucidate the LWMS’s nomological net with relevant psychological (i.e., psychological well-being, work engagement, sleeping hours, suicidal thoughts) and physiological health measures (i.e., physiological health problems, alcohol and smoking consumption, body mass index) as well as with important organizational criteria (i.e., work performance, turnover intention, absenteeism) and with self-labeling victim status. Evaluation of different measurement invariance models confirm metric and (partial) scalar invariance across all compared groups. Neither age, gender, nor the most frequent areas of occupation in Luxembourg represent important risk factors for workplace bullying exposure. Regarding criterion validity, with the exceptions of alcohol and smoking consumption, all proposed psychological and physiological health measures as well as organizational criteria are meaningfully associated with the LWMS. In summary, the LWMS is especially useful, when the identification of workplace bullying exposure risk groups or cross-cultural research is of concern. The third study (Chapter 4) aimed to test specific organizational risk factors of the occurrence of workplace bullying. Specifically, competition and passive avoidant leadership style were tested as risk factors of workplace bullying (exposure and perpetration) assessed with two assessment methods (behavioral experience and self-labeling method). Consistent with theoretical reasoning and prior research, results demonstrated that competition as well as passive avoidant leadership style are important risk factors of workplace bullying exposure. Moreover, results showed that the same effects showed up for perpetration. Even more interesting, passive avoidant leadership style acted as a moderator on the effect of competition on workplace bullying exposure. In line with theory, competition is stronger related to workplace bullying exposure, when passive avoidant leadership is high. Thus, passive avoidant leadership style can be considered a disruptive factor reinforcing the negative association with competition. Regarding workplace bullying perpetration the same moderation effect was only found for the self-labeled assessment method. The fourth study (Chapter 5) aimed to identify different psychological mechanisms (i.e., psychological contract violation and frustration of basic needs) that link being target of workplace bullying and health, attitudinal and behavioral outcomes. Furthermore, their relative impact and importance on different outcomes were highlighted. Psychological contract violation was an important mediator for decreased job satisfaction and higher turnover intentions, whereas frustration of autonomy mediated the effect between workplace bullying exposure and increased levels of burnout, frustration of competence mediated the effect of bullying exposure on decreased work performance and frustration of relatedness was strongly associated with decreased well-being and vigor. Results showed that feelings of psychological contract violation and frustration of basic needs accounted for unique variation in many outcome variables, pointing to the individual contribution of both psychological mechanisms. The present thesis deepens our understanding of the organizational circumstances under which workplace bullying is more likely and the psychological mechanisms that link the bullying exposure with several outcomes. These results can guide possible prevention and intervention strategies. [less ▲]

(1) Research has shown that a poor psychosocial working environment can trigger workplace mobbing, which is a serious phenomenon that is costly to organizations and has various negative consequences of those targeted. (2) The present study describes psychosocial workplace predictors, prevalence and changes of workplace mobbing in Luxembourg for the last three years. (3) For measuring mobbing behavior, we use the Luxembourg Workplace Mobbing Scale (LWMS), a new short scale of workplace mobbing experience that was tested and validated in three different language versions (German, French and Luxembourgish). We use the first, second and third wave (planed for August 2015) of the Quality-of-Work-Index Luxembourg (Steffgen & Kohl 2013; Sischka & Steffgen 2015). Each wave is a representative sample of about 1530 employees working in Luxembourg (Data collection by Computer-assisted Telephone Interviewing). (4) Results of correlation and regression analysis with data of the first and second wave support the ‘psychosocial working environment’-hypothesis: Mobbing victims evaluate their psychosocial working environment worse (in terms of satisfaction, meaningfulness of work, respect of the superior and the whole organization, communication and feedback, cooperation among colleagues, mental strain) than persons that are not affected by mobbing. In addition, mobbing victims are more likely to report a higher stress level, symptoms of a burnout and addictive behavior, compared to non-victims. Finally, changes of mobbing exposure over the three measurement points will be discussed. (5) Focus of interventions for mobbing should be on improving the general quality of work and the collective working environment. [less ▲]
