Transforming variables before analysis or applying a transformation as a part of a generalized linear model are common practices in organizational research. Several methodological articles addressing the topic, either directly or indirectly, have been published in the recent past. In this article, we point out a few misconceptions about transformations and propose a set of eight simple guidelines for addressing them. Our main argument is that transformations should not be chosen based on the nature or distribution of the individual variables but based on the functional form of the relationship between two or more variables that is expected from theory or discovered empirically. Building on a systematic review of six leading management journals, we point to several ways the specification and interpretation of nonlinear models can be improved.

The Relationship

The article explores the relationship of the person with the hole through both literal and metaphorical situations. On the one hand, it points up the body in seclusion and suspended in a time interval, as in the case of the accident at the mine in San José (Chile) or works by artists like J. Wall, G. Schneider or R. Ondák. In this way, opposed feelings evoke the experiences of waiting and/or punishment, which are explanatory of a confined body or a hole. Literature, cinema and art deal with these events from multiple aspects, which become existential allegories about the individual. On the other hand, the act of digging gains prominence as a symbol of work, but also of the absurd. Recalling the ambivalence that may suggest a person making a hole, this article carries out a drift through works by artists of different generations and contexts, such as C. Burden, M. Heizer, F. Miralles, Geliti, S. Sierra, F. Alÿs, M. Salum, X. Ristol or N. Güell. A series of clearly performative or conceptual works, where the act of digging, drilling, burying or unburying become common practices that show the diversity of meanings and intentions.

The Relationship

Research on the relationship between teacher characteristics and teacher effectiveness has been underway for over a century, yet little progress has been made in linking teacher quality with factors observable at the time of hire. To extend this literature, we administered an in-depth survey to new math teachers in New York City and collected information on a number of nontraditional predictors of effectiveness, including teaching-specific content knowledge, cognitive ability, personality traits, feelings of self-efficacy, and scores on a commercially available teacher selection instrument. We find that only a few of these predictors have statistically significant relationships with student and teacher outcomes. However, the individual variables load onto two factors, which measure what one might describe as teachers' cognitive and noncognitive skills. We find that both factors have a moderately large and statistically significant relationship with student and teacher outcomes, particularly with student test scores.

Expertise is one of the ways one can make one’s behaviors become automatic, and with consumption it is no different. Explanatory models of this sort of behavior described in the literature up to now have considered only conscious or rational buying, and do not apply to automatic buying. The model proposed here is inspired by, and adapted from, the behavior analyses, integrating variables that have typically been neglected in the traditional models, such as contextual variables. This study aimed to describe the relationship between the reports of behavior linked to the consumption of esthetics (operationalized in four variables: commenting, getting information, using cosmetic products and services) and the individual variables and those of the setting where purchases related to beauty were made. In order to do so, 953 Brazilian women responded to an online questionnaire. The model was tested and partially confirmed. Contextual social-psychological variables were the only ones to predict routine buying. Demographic and individual variables did not account for the variance explanation of the behaviors measured. It is suggested that further studies should use and contribute to this model to enhance the understanding of automatic buying.

Monitoring the level of individual factors or performance predispositions is an essential part of athlete´s training process. The article discusses the results of the diagnostic performance predispositions research of the selected group of tennis players. In the research, we first made a selection of players according to the criterion of the frequency of participation in testing and the other criterion was the performance level, ranking, they reached. In the next phase, we analyzed the individual test results of the players in the long-term perspective. The final step was to assess the relationship between age, the results of the test battery and game performance. Due to the small number of measurements and the complexity of sport performance in tennis we did not expect very tight dependence (correlation) of individual variables. We came to the conclusion that by all observed players a high level of motor performance predisposition were recorded which corresponds with their high performance in tennis and ranking, although statistical dependence was not proven.

This article has two purposes: (a) to examine the relationship between intercultural power relations and the widespread practice of accent discrimination and (b) to underscore the ramifications of accent discrimination both for the individual and for global society as a whole. First, authors review social theory regarding language and group identity construction, and then go on to integrate more current studies linking accent bias to sociocultural variables. Authors discuss three examples of intercultural accent discrimination in order to illustrate how this link manifests itself in the broader context of international relations (i.e., how accent discrimination is generated in situations of unequal power) and, using a review of current research, assess the consequences of accent discrimination for the individual. Finally, the article highlights the impact that linguistic discrimination is having on linguistic diversity globally, partially using data from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and partially by offering a potential context for interpreting the emergence of practices that seek to reduce or modify speaker accents.

Abstract. The individual attitudes of every single team member are important for team performance. Studies show that each team member’s collective orientation – that is, propensity to work in a collective manner in team settings – enhances the team’s interdependent teamwork. In the German-speaking countries, there was previously no instrument to measure collective orientation. So, I developed and validated a German-language instrument to measure collective orientation. In three studies (N = 1028), I tested the validity of the instrument in terms of its internal structure and relationships with other variables. The results confirm the reliability and validity of the instrument. The instrument also predicts team performance in terms of interdependent teamwork. I discuss differences in established individual variables in team research and the role of collective orientation in teams. In future research, the instrument can be applied to diagnose teamwork deficiencies and evaluate interventions for developing team members’ collective orientation.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

Existential Perspective

Virginia Woolf and Being-in-the-world: A Heideggerian Study explores Woolf’s treatment of the relationship between self and world from a phenomenological-existential perspective. This study presents a timely and compelling interpretation of Virginia Woolf’s textual treatment of the relationship between self and world from the perspective of the philosophy of Martin Heidegger. Drawing on Woolf’s novels, essays, reviews, letters, diary entries, short stories, and memoirs, the book explores the political and the ontological, as the individual’s connection to the world comes to be defined by an involvement and engagement that is always already situated within a particular physical, societal, and historical context. Emma Simone argues that at the heart of what it means to be an individual making his or her way in the world, the perspectives of Woolf and Heidegger are founded upon certain shared concerns, including the sustained critique of Cartesian dualism, particularly the resultant binary oppositions of subject and object, and self and Other; the understanding that the individual is a temporal being; an emphasis upon intersubjective relations insofar as Being-in-the-world is defined by Being-with-Others; and a consistent emphasis upon average everydayness as both determinative and representative of the individual’s relationship to and with the world.

Was to conduct a systematic review of data on the relationship between polymorphisms genes of detoxification system and development of preeclampsia (РЕ). Рresents the main genes of detoxification system (GSTPI, GSTМI, GSTТI, GРХI, ЕРНХI, SOD-2, SOD-3, CYPIAL, MTHЕR, MTR) and their functions. Of interest is the possibility of calculating the individual risk of PE based on the results about the presence of a combination of different polymorphisms in the genotype of the female. Question about early diagnosis of РЕ remains controversial and not fully understood. It is necessary to conduct further in-depth, extended study of this problem. Key words: preeclampsia, oxidative stress, genes of the detoxification system.
