An augmented data scoring algorithm for maximum likelihood

The expectation-maximization (EM) method facilitates computation of max¬imum likelihood (ML) and maximum penalized likelihood (MPL) solutions. The procedure requires specification of unobservabie complete data which augment the measured or incomplete data. This specification defines a conditional expectation of the complete data log-likelihood function which is computed in the E-stcp. The EM algorithm is most effective when maximizing the iunction Q{0) denned in the F-stnp is easier than maximizing the likelihood function.

The Monte Carlo EM (MCEM) algorithm of Wei & Tanner (1990) was introduced for problems where computation of Q is difficult or intractable. However Monte Carlo can he computationally expensive, e.g. in signal processing applications involving large numbers of parameters. We provide another approach: a modification of thc standard EM algorithm avoiding computation of conditional expectations.     

Where to from here? Blue passports,family, career—and Donald Trump

Abstract

In this essay, we offer our stories of family and migration under a Donald Trump presidency. We are a lesbian couple; one of us is a citizen of the United States while the other is a citizen of a Muslim country. We use autoethnographic methods to explore and interrogate our “messy and fabulous” journey of liminality; our journey of belonging and exclusion, where we grapple with issues related to sexuality, family, career, and citizenship. Our “voices” are used both individually and in unison, to highlight our intersectional and relational selves. We intend this work to contribute to the many ways we can better understand and appreciate the bountiful and colorful vistas of lesbian families’ migrant experiences.     

Orientalism and Russian speaking minority regions in Europe: representing Narva

ABSTRACT

This paper uses the concept of orientalism to propose a framework for understanding the relationship between international news media and individual representations of minority groups in Europe. Even though the case study focuses on Narva, Estonia, the model here provides a basis for comparing the identity formation practices, particularly of geographically separated Russian speaking minority groups in Europe. Narva’s large Russian speaking population and geographical proximity to Russia have been pinpointed as security concerns due to the convenient source of information and mass media sponsored by the Russian Federation causing a misrepresentation of Russian speaking minority groups in international media.     

How discrimination in adoptive,foster, and medical systems harms LGBTQ+ families: Research on the experiences of prospective parents

Abstract

LGBTQ+?people face multiple challenges to parenthood because of barriers such as discriminatory legislation and policies influencing foster parenting, adoption, and reproductive health services. This study documents these obstacles and examines their impact through a grounded theory analysis of interviews of LGBTQ+?prospective parents. Stressors included social isolation, unnecessary medicalization, prohibitive financial costs related to accessing social and medical services (sometimes across state lines), and being denied services, parental leave, and insurance coverage. Findings indicate that heteronormative attitudes and discrimination can lead to debilitating and enduring harm upon the economic, emotional, and relational well-being of growing LGBTQ+?families.     

Nature and social work pedagogy: How U.S. social work educators are integrating issues of the natural environment into their teaching

ABSTRACT

The article presents a study of how U.S. social work educators are including discussion, exercises, readings, and other pedagogical approaches to the natural environment into their classrooms. The findings are part of a larger, naturalistic study that gathered data using a semi-structured interview format. The three major themes that emerged were human behavior theory, ecological and environmental justice, and environmental sustainability. The participants are introducing issues of the natural environment using varied pedagogical techniques including readings, in-class discussions and exercises, service learning, assignments, including written and practical work, research, self-awareness exercises, and class facilitation. Questions for further investigation of social work and the natural environment are included.     

First-time mothers’ birth beliefs,preferences, and actual birth: A longitudinal observational study

Problem

Birth preferences, such as mode and place of birth and other birth options, have important individual and societal implications, yet few studies have investigated the mechanism which predicts a wide range of childbirth options simultaneously.

Durkheim and realism

This article examines Durkheim's relationship to realism. I argue that there is enough prima facie evidence of realist commitments in his work that our task should be to consider what kind of realist Durkheim was. I discuss, first of all, Durkheim's epistemics and follow that analysis with a discussion of metaphysical realism in his texts. The first part of the paper covers a wide range of his work; the second part focuses primarily on The Elementary Forms of Religious Life. In a final concluding section, I go on to consider how his epistemic arguments and his philosophical realism might work together to support important parts of his general sociology. Realism is not often brought to bear on Durkheim's work. When it has been, Durkheim has been identified as a naïve realist. These interpretations of Durkheim do not recognize the sophistication of contemporary realism, which does not reduce to naïve representationalism. This paper will sort out Durkheim's realist commitments in his texts, and in light of the variety of realisms consistent with “sophisticated” (that is, non-naïve) realism.     

Six‐ and 9‐Month‐Old Infants Discriminate Between Goals Despite Similar Action Patterns

Behne, Carpenter, Call, and Tomasello (2005) showed that 9‐ to 18‐month‐olds, but not 6‐month‐olds, differentiated between people who were unwilling and unable to share toys. As the outcome of the two tasks is the same (i.e., the toy is not shared), the infants must respond to the different goals of the actor. However, visual habituation paradigms have shown an earlier onset of goal awareness. The present study reconciles this disparity by replicating the findings of Behne et al. with both 6‐ and 9‐month‐olds, using similar tasks and additional response measures.     

Der Stand der Coachingforschung: Kernergebnisse der vorliegenden Metaanalysen

The present article provides a quantitative overview of the state of coaching research. It first provides an insight into the status quo of the academic publishing landscape. Afterwards, results of the four meta-analyes that have been published on coaching research up to now are summarized. First, results on the efficacy of coaching or coaching outcomes are presented. Findings for different outcome measures as well as different study designs are reported. Next, results on predictors of coaching success are presented. They include specific features of the coaching process and setting, the coach-coachee-relationship as well as characteristics of coaches and coachees. The article closes with a summary and an assessment of the state of coaching research.     

Schulleitungscoaching – Konzeption und Ausbildungsevaluation

Since principals in schools are increasingly turning into managers of educational institutions, coaching approaches have an increasing importance. Accordingly, the Bavarian Ministry for Education and Culture in cooperation with the National Institute for Quality in Schools and Educational Research and the Academy of Teacher Education and Personnel Management has introduced the project ?Coaching – an Instrument to Professionalise School-based Leadership“. The project involves exemplary coachings of school management teams and the training of coaches with a focus on school-related issues at the University of Innsbruck. The training of coaches is based on a special curriculum, which was evaluated using a multi-methods approach. The outcomes show that the coaching model is accepted by coaches and that the training is of high quality
