Who Is a Social Worker?

Defining social workers for the purposes of research is not as straightforward as it sounds. To date, researchers who have examined social workers as a group have used a variety of sampling methods. Multiple methods speak to the variety of options for defining social workers. Understanding membership within the profession is a precondition to understanding research about the behavior of those within the profession. This research note explores these sampling methods in detail. Each has its advantages, but none are without their own disadvantages, some of which bias their view of the profession. As researchers who have considered the political behavior of social workers, we consider six methods for sampling social workers that have been used to understand their behavior in this specific domain. Importantly, the sampling methods examined here can be applied to research about social workers outside of politics. These include sampling (1) members of professional organizations, (2) licensed social workers, (3) social work students, (4) graduates of social work programs, (5) social work faculty, and (6) members of social work-related occupations. After reviewing the advantages and disadvantages of each, we provide scholars a table for reference. The authors recommend that the Council on Social Work Education, National Association of Social Workers, and several other professional associations pull together members to explore a unified definition of social work through integrated practice and refrain from focusing on what makes us different

Clinical Social Workers, Gender, and Perceptions of Political Participation

Political participation to create social change is considered a professional and ethical imperative for social workers. Although researchers have examined overall political participation by social workers, little is known about how clinical social workers participate and the broader societal factors that influence their political participation. A critical phenomenological methodology was used with a sample of 23 clinical social workers from New England states to (1) identify how socio-political forces influenced their political activity; and, (2) understand how the concept of power affected individuals’ level of engagement or inclination toward the political process. This article describes one of the study’s major findings. Female participants described themselves as unqualified and/or unknowledgeable in the political sphere, with low levels of ambition and confidence to engage in political processes. Many female participants also described the challenges of achieving a work-life balance between their careers and traditional gender-based roles with little time left for political engagement. Social work education and policy advocacy can affect change that will increase the internal and external efficacy of social workers and create a policy environment that allows more options for all social workers in balancing the demands of professional and personal lives

Genome-wide signatures of population bottlenecks and diversifying selection in European wolves

Genomic resources developed for domesticated species provide powerful tools for studying the evolutionary history of their wild relatives. Here we use 61K single-nucleotide polymorphisms (SNPs) evenly spaced throughout the canine nuclear genome to analyse evolutionary relationships among the three largest European populations of grey wolves in comparison with other populations worldwide, and investigate genome-wide effects of demographic bottlenecks and signatures of selection. European wolves have a discontinuous range, with large and connected populations in Eastern Europe and relatively smaller, isolated populations in Italy and the Iberian Peninsula. Our results suggest a continuous decline in wolf numbers in Europe since the Late Pleistocene, and long-term isolation and bottlenecks in the Italian and Iberian populations following their divergence from the Eastern European population. The Italian and Iberian populations have low genetic variability and high linkage disequilibrium, but relatively few autozygous segments across the genome. This last characteristic clearly distinguishes them from populations that underwent recent drastic demographic declines or founder events, and implies long-term bottlenecks in these two populations. Although genetic drift due to spatial isolation and bottlenecks seems to be a major evolutionary force diversifying the European populations, we detected 35 loci that are putatively under diversifying selection. Two of these loci flank the canine platelet-derived growth factor gene, which affects bone growth and may influence differences in body size between wolf populations. This study demonstrates the power of population genomics for identifying genetic signals of demographic bottlenecks and detecting signatures of directional selection in bottlenecked populations, despite their low background variability.Heredity advance online publication, 18 December 2013; doi:10.1038/hdy.2013.122

The Three-Legged Stool of Voter Engagement

Disparities in voter turnout have increased significantly over the past four decades. Members of historically oppressed groups, those who are low-income, and or who have lower levels of education vote at significantly lower rates than white, wealthy and or more educated community members. These disparities correlate directly to political power and the eventual allocation of resources by elected officials. Therefore, eliminating these disparities through targeted voter engagement with client groups is particularly important for the profession of social work. This article describes the conceptualization of voter engagement as a three-legged stool, consisting of voter registration, regular voting, and basing voting decisions on self-interest. Without attention to all three legs, the potential for generating political power collapses, resulting in minimal influence on elected officials

The Serendipitous Discovery of a Group or Cluster of young Galaxies at z=2.40 in Deep Hubble Space Telescope WFPC2 Images

We report the serendipitous discovery of a group or cluster of young galaxies at $z\simeq$2.40 in a 24-orbit HST/WFPC2 exposure of the field around the weak radio galaxy 53W002. Potential cluster members were identified on ground-based narrow-band redshifted Ly$\alpha$ images and confirmed via spectroscopy. In addition to the known weak radio galaxy 53W002 at z=2.390, two other objects were found to have excess narrow-band Ly$\alpha$ emission at $z\simeq$2.40. Both have been spectroscopically confirmed, and one clearly contains a weak AGN. They are located within one arcminute of 53W002, or $\sim0.23h_{100}^{-1}$Mpc ($q_o$=0.5) at $z\simeq$2.40, which is the physical scale of a group or small cluster of galaxies. Profile fitting of the WFPC2 images shows that the objects are very compact, with scale lengths $\simeq$0\farcs 1 ($\simeq0.39h_{100}^{-1}$kpc), and are rather faint (luminosities < L*), implying that they may be sub-galactic sized objects. We discuss these results in the context of galaxy and cluster evolution and the role that weak AGN may play in the formation of young galaxies.Comment: Accepted for publication in The Astrophysical Journal (Letters). 13 pages of gzip compressed and uuencoded PS.

The Top Ten List of Gravitational Lens Candidates from the HST Medium Deep Survey

A total of 10 good candidates for gravitational lensing have been discovered in the WFPC2 images from the HST Medium Deep Survey (MDS) and archival primary observations. These candidate lenses are unique HST discoveries, i.e. they are faint systems with sub-arcsecond separations between the lensing objects and the lensed source images. Most of them are difficult objects for ground-based spectroscopic confirmation or for measurement of the lens and source redshifts. Seven are ``strong lens'' candidates which appear to have multiple images of the source. Three are cases where the single image of the source galaxy has been significantly distorted into an arc. The first two quadruply lensed candidates were reported in Ratnatunga et al 1995 (ApJL, 453, L5) We report on the subsequent eight candidates and describe them with simple models based on the assumption of singular isothermal potentials. Residuals from the simple models for some of the candidates indicate that a more complex model for the potential will probably be required to explain the full structural detail of the observations once they are confirmed to be lenses. We also discuss the effective survey area which was searched for these candidate lens objects.Comment: 26 pages including 12 figures and 10 tables. AJ Vol. 117, No.

Creating a Culture of Voting in Direct and Generalist Practice: Training Field Instructors

Social workers have an ethical responsibility to be engaged in policy change, regardless of their practice area or specialization. Voter engagement and the importance of political power through voting is often overlooked in the literature as a valid and important component of social work practice. Creating a culture of nonpartisan voter engagement in practice settings can help empower individuals who have been historically and intentionally disenfranchised from our electoral system. Training for field instructors, faculty, and field staff is a key aspect of voter engagement in social work education. Unfortunately, social work education is unlikely to include substantive content on voter engagement or its connection to social work practice and impact. This article presents one component of a model for integrating voter engagement into social work education: the provision of training for field instructors on nonpartisan voter engagement at two universities over two years. Evaluation findings suggest that pre-existing levels of political efficacy affect the reaction of field instructors to nonpartisan voter engagement training. Furthermore, findings indicate that field instructors who receive voter engagement training are more likely to serve as resources for their students and to consider voter engagement as part of their own practice. We offer evidence on the important role field educators can play in the success of the larger national effort to integrate voter engagement in social work education. Increasing awareness of what social workers, nonprofit, and public agencies are allowed--or even required--to do is a critical first step
