Nonparametric Bayesian inference for ergodic diffusions

The problem of nonparametric drift estimation for ergodic diffusions is studied from a Bayesian perspective. In particular, Gaussian process priors are exhibited that yield optimal contraction rates if the drift function belongs to a smoothness class.     

Detecting bliss synergy in in vivo combination studies with a tumor kinetic model

Linear models are generally reliable methods for analyzing tumor growth in vivo, with drug effectiveness being represented by the steepness of the regression slope. With immunotherapy, however, not all tumor growth follows a linear pattern, even after log transformation. Tumor kinetics models are mechanistic models that describe tumor proliferation and tumor killing macroscopically, through a set of differential equations. In drug combination studies, although an additional drug‐drug interaction term can be added to such models, however, the drug interactions suggested by tumor kinetics models cannot be translated directly into synergistic effects. We have developed a novel statistical approach that simultaneously models tumor growth in control, monotherapy, and combination therapy groups. This approach makes it possible to test for synergistic effects directly and to compare such effects among different studies.     

Instructor Active Empathic Listening and Classroom Incivility

Instructor listening skill is an understudied area in instructional communication research. This study looks at teachers’ active empathic listening behavior association with student incivility. Scholars recognize student incivility as a growing problem and have called for research that identifies classroom behaviors that can affect classroom climate. A total of N = 434 undergraduate students were surveyed about their observations of student incivility in their classes, their perceptions of their instructor’s use of active empathic listening and nonverbal involvement, class size, instructor gender, and estimated instructor age. After controlling for nonverbal involvement, instructor age, instructor gender, and class size, results suggest active empathic listening associates negatively with three types of classroom incivility. Both class size and instructor nonverbal immediacy also emerged as predictors of student incivility.     

The nature and culture of social work with children and families in long‐term casework: Findings from a qualitative longitudinal study

Social work in the United Kingdom is preoccupied with what social workers cannot do due to having limited time to spend with service users. Yet remarkably little research has examined what social workers actually do, especially in long‐term relationships. This paper draws from an ethnographic study of two social work departments in England that spent 15 months observing practice and organizational life. Our findings show that social work some of the time has a significant amount of involvement with some service users and the dominant view that relationship‐based practice is rarely achieved is in need of some revision. However, families at one research site received a much more substantial, reliable overall service due to the additional input of family support workers and having a stable workforce who had their own desks and were co‐located with managers in small team offices. This generated a much more supportive, reflective culture for social workers and service users than at the second site, a large open plan “hot‐desking” office. Drawing on relational, systemic, and complexity theories, the paper shows how the nature of what social workers do and culture of practice are shaped by the interaction between available services, office designs, and practitioners', managers', and service users' experiences of relating together.     

Relationships in a new country: A qualitative study of the social connections of refugee youth resettled in South Australia

Australia's approach to immigration, as internationally, is largely concerned with state sovereignty, border protection and restrictionism towards asylum seekers. However, with just under a million refugees currently residing in Australia, and with 13,750 more added to this number each year, there is also an interest in ensuring that those who are granted humanitarian protection are socially integrated. This article reports on a qualitative investigation of the integration experiences of 85 refugee adolescents aged 13–17 years resettled in Adelaide, South Australia. It explores, in particular, the role of social connectedness in the integration process. Relationships with family, ethnic group and host country are believed to affect multiple and interrelated integration outcomes including language acquisition, cultural knowledge, belonging, identity, civic engagement, social and economic participation, and access to public services. This research found that young people must negotiate the integration process with variable, and in many cases limited, support from the network of social connections surrounding them. We suggest that policy and programmes which strengthen the relationships young people have with others have the potential to enhance integration outcomes.     

Has Migration Been Beneficial for Migrants and Their Children?

The study compares the social mobility and status attainment of first‐ and second‐generation Turks in nine Western European countries with those of Western European natives and with those of Turks in Turkey. It shows that the children of low‐class migrants are more likely to acquire a higher education than their counterparts in Turkey, making them more educationally mobile. Moreover, they successfully convert this education in the Western European labor market, and are upwardly mobile relative to the first generation. When comparing labor market outcomes of second generations relative to Turks in Turkey, however, the results show that the same level of education leads to a higher occupation in Turkey. The implications of these findings are discussed.     

How social workers reflect in action and when and why they don’t: the possibilities and limits to reflective practice in social work

The need for professionals to use reflection to learn about and develop their practice is now a universally stated goal. In social work however there has been little research into whether and how reflection in action actually occurs and this paper explores the possibilities and limits to reflective practice by drawing on research that observed encounters between social workers and children and families as the work was being conducted in real time. The findings show that practitioners often do reflect in action by elevating their minds above the interactions they are having so that they can think critically about and adjust what they are doing. But there are times when reflection is either limited or non-existent because practitioners defend themselves against the sensory and emotional impact of the work and the high anxiety they are experiencing. Drawing on psychoanalysis and social theories of the body and senses, the paper argues for a revision of the concept of reflective practice to take account of how the self is defended. The limits to reflection must be fully recognised while seeking ways to develop the capacity of practitioners to think clearly and critically so that vital insights about service users and the helping process can occur.     

Deaf and hard of hearing faculty in higher education: enhancing access,equity, policy,and practice

Higher education institutions are often well prepared in terms of accommodation policies and practices for disabled students. Ironically, campuses are often not prepared once disabled academics return as faculty. Most are particularly unfamiliar with the unique access needs of deaf or hard of hearing academics. This can result in career hindrances to employment and tenure, as well as potential losses to campuses in terms of diversity. Background and substantiation on this access issue is provided along with recommendations for policy-making and practices for campuses that are geared to ensuring career success for deaf and hard of hearing faculty.
