At the intersection of science,technology, engineering,and mathematics and business management in Canadian higher education: An intentional equity,diversity, and inclusion framework

In this study, the authors address the persistent discrimination cis women face in the Canadian science, technology, engineering and mathematics (STEM) higher education context. Pulling on the notion of interrelationships that cross educational faculty boundaries and on intersectionality scholarship to unsettle the structural and disciplinary domains of power, the authors ask, “How can business education and STEM education work together with respect to social considerations, such as gender/race/ethnicity/etc., and social equity and inclusivity, within the Canadian higher education system?” This study aims to build on these interrelationships among diverse, complex individuals who participated in a graduate-level STEM and business management summer institute to provide an evidence-based and intentional equity, diversity and inclusion (EDI) framework for STEM higher education contexts. Using a mixed-methods approach, which saw data collection via a survey instrument and semi-structured interviews, the subsequent quantitative analysis points to expanding interrelationships to broader areas beyond STEM and business management programs. The close reading of the collected qualitative data, via antenarrative spirals, elevates the participants' complexities beyond focusing “just” on their intersecting identities to looking at their perceptions of STEM fields, the order that ensues and the potential for the undoing of that order. The findings, results, and analyses of these collected data led to an intentional EDI framework, the main contribution of this study, constructed into three main pillars represented by the figure of a tree: the foundational elements (roots) built on individuals' complexities and experiences of Othering, the interrelationships (trunk) possible across various educational and professional dimensions, and a call to structural change initiatives (branches) with the possibility for growth in other areas. This work then contributes to not only filling a significant literature gap and building awareness regarding EDI concerns in STEM contexts via active interrelationship-building activities but also to unsettling the structural and disciplinary domains of power by embracing a holistic strategy to address systemic discriminatory practices in the Canadian STEM higher education context.     

Risk Assessment for Aflatoxin: An Evaluation Based on the Multistage Model

Lifetime cancer potency of alfatoxin was assessed based on the Yeh et al. study from China in which both aflatoxin exposure and hepatitis B prevalence were measured. This study provides the best available information for estimating the carcinogenic risk posed by aflatoxin to the U.S. population. Cancer potency of aflatoxin was estimated using a biologically motivated risk assessment model. The best estimate of aflatoxin potency was 9 (mg/kg/day)⁻¹ for individuals negative for hepatitis B and 230 (mg/kg/day)⁻¹ for individuals positive for hepatitis B.     

Distribution of the quotient of noncentral normal random variables

The Mellin convolution is used to derive in analytical form an exact 3-parameterprobabilitydensity function of the quotient of two noncentral normal random variables. In contrast with the 5-parameter probability density function previously derivedby Fieller (1932) and Hinkley (1969), this 3-parameter probability density function is feasible for computer evaluation of the mean and cumulative distribution function, which are needed, for example, when dealing with estimation and distribution problems in regression analysis and sampling theory. When the normal variables are independent, the probability density function reduces to a 2-parameter function, for which a computer program is operational. An illustrative example is given for one set of parameters when the normal variables are independent, in which themean and functional form of the probability density function are presented, together with a brief tabulation of the probability density function.     

Consistency of maximum likelihood estimators in a large class of deconvolution models

We consider the maximum likelihood estimator $\hat{F}_n$ of a distribution function in a class of deconvolution models where the known density of the noise variable is of bounded variation. This class of noise densities contains in particular bounded, decreasing densities. The estimator $\hat{F}_n$ is defined, characterized in terms of Fenchel optimality conditions and computed. Under appropriate conditions, various consistency results for $\hat{F}_n$ are derived, including uniform strong consistency.

Advances in Families and Health Research in the 21st Century

We review research on families and health published between 2000 and 2009 and highlight key themes and findings from innovative, methodologically rigorous studies. Whereas research in prior decades focused primarily on whether family structure affects child and adult health, contemporary research examines the contextual and processual factors that shape for whom, for which outcomes, and under what conditions families affect mental and physical health. We discuss how family structure, transitions, and processes within families of origin affect children's health over the life course. We then examine the effects of marital status, transitions, and quality for adult health. We point out limitations in current research, discuss implications of recent findings for policy, and highlight theoretical and methodological directions for future research.     

Accuracy and bias in self-perception of performance: Narcissism matters in Korea as well

Debates regarding the nature of self-enhancement versus accurate self-assessment have been active among psychologists for decades. More recently, researchers have become interested in the panculturality of self-enhancement. Some researchers argue that self-enhancement is universal and present within all cultures. Others declare self-enhancement to be a Western tendency, with self-diminishment being the norm among East Asians. Importantly, the majority of such studies have not compared self-perceptions against objective external criteria, especially those with East Asians. Furthermore, the link between narcissism and self-enhancement has been largely overlooked within Korean samples. To address such gaps, we utilized scores on an objective test as a criterion to investigate the accuracy of Koreans’ self-assessments of performance, as well as how individual differences in narcissism are related to such assessments. A sample of Korean students (N = 146; 71 women) completed self-report measures of narcissism and self-esteem, and took a listening comprehension quiz. Estimated and actual scores were collected and used to compute self-enhancement scores. Results demonstrated that Koreans’ self-perceptions of performance on the quiz were quite accurate. As has been found in Western cultures, narcissism was related to self-enhancement.     

Subjektivierung der Biographie. Lebensorientierungen und Anspruchshaltungen

Opposing the tendency within current analyses in the social sciences to draw a conclusion from present changes in people??s working and living conditions to corresponding social-psychic dispositions, this article both theoretically and empirically develops the thesis that people??by considering structural preconditions??put demands on themselves and structure their resources and possible courses of action. In order to understand how this is done, the article develops the concept of ??life-orientation??. By means of four exemplary typifications of life-orientations gained from a research project on employees?? demands on work, we will demonstrate that established beliefs about actual forms of subjectivity are in need of correction.     

The same and the other: male childcare workers managing identity dissonance

As childcare workers, men are in a contested position. On the one hand, they are in danger of being depicted as the pedophile; on the other hand, they are expected to bring something new and innovative to the thus-far female-dominated field. These men are experiencing ‘identity dissonance’ and have to find ways to manage and facilitate legitimate subject positions as both childcare workers and as men. Applying a perspective of discursive positioning, this article discusses men's positioning practices in nine qualitative interviews conducted with male childcare workers in German-speaking Switzerland. We identified a total of six discursive practices that men engage in to manage identity dissonance and construct a legitimate subject position. We found that men are engaging in a greater variety of practices than have been discussed so far. Unlike findings from other studies of men in female-dominated occupations, ours do not point to a clear-cut typology with regards to hegemonic and alternative masculinities; instead they show a variety of practices that are mobilized throughout all interviews.
