On three and four vicious walkers

We establish a reflection principle for three lattice walkers and use this principle to reduce the enumeration of configurations of three vicious walkers to the enumeration of configurations of two vicious walkers. More precisely, the reflection principle leads to a bijection between three walks (L₁, L₂, L₃) such that L₂ intersects both L₁ and L₃ and three walks (L₁, L₂, L₃) such that L₁ intersects L₃. Hence we find a combinatorial interpretation of the formula for the generating function for the number of configurations of three vicious walkers, originally derived by Bousquet-Mélou by using the kernel method, and independently by Gessel by using tableaux and symmetric functions. This answers a question posed by Gessel and Bousquet-Mélou. We also find a reflection principle for four vicious walks that leads to a combinatorial interpretation of a formula derived from Gessel's theorem.     

Better educational inclusion of migrant children in urban schools? Exploring the influences of the population control policy in large Chinese cities

The educational inclusion of rural–urban migrant children in Chinese urban schools has been promoted in the past decades. This paper provides a contextualized interpretation of recent policy developments governing large Chinese cities and evaluates its impact upon the status of migrant children's education. Drawing on data collected from 1,331 migrant children in urban inclusive schools, this study compared current migrant children's family backgrounds and psychological sense of belonging at school in relation to educational outcomes at the primary education level. Results showed that migrant children's socioeconomic status (SES) levels were slightly higher than their counterparts in inclusive schools and a salient SES stratification of migrant students was found. This correlates with students’ reports of fewer incidences of discrimination than hypothesized. Furthermore, capital in migrant families was positively associated with the psychological sense of belonging and academic achievement. These results reveal a significant change to migrant students’ SES as a result of the recent population control policy pertaining to China's large cities since 2014. Implications for research and educational practice, especially with at‐risk migrant students of low‐SES, are discussed.     

The Social Vulnerability Scale for Older Adults: An Exploratory and Confirmatory Factor Analytic Study

The Social Vulnerability Scale (SVS), a 22-item informant report of vulnerability to exploitation and, in particular, financial exploitation of older adults, was administered to 266 respondents who assessed the social vulnerability of a significant other aged 50 years or over, either a person with dementia or other neurological condition (n?=?116), or a healthy adult (n?=?150). Exploratory factor analysis in the combined sample revealed a 15-item two-factor solution labeled gullibility and credulity. Stability in factor structure was established in an independent sample (n?=?123) using confirmatory factor analysis, and sound reliability (internal consistency) and validity (known-groups) were demonstrated. The SVS15 is a potentially useful instrument for assessing older adults' vulnerability to exploitation.     

“Do They Think I Am a Pack Rat?”

This case study presents details of the life of one older man who lived in seclusion and squalor, surrounded by hoarded possessions. This man was one participant of a focused ethnography of eight older adults who received home care. All participants in the original ethnography were identified by their community care coordinators as exhibiting hoarding behaviors. The case study presented here provides rich narrative and photographic detail in order to add strength to what has already been presented in previous research articles about compulsive acquisition. The narratives reveal examples of debilitating dysfunction, distress associated with decision making, broad acquisition of free things, compulsive buying, and ritualistic discarding. Quotes included in the case study stem from the original ethnography.     

A Preliminary Comparison Study of Online and Face-to-Face Counseling: Client Perceptions of Three Factors

This preliminary study examined the similarities and differences between online and face-to-face counseling with regard to general mental health, working alliance, and social presence. Participants included 50 current counseling clients (37 face-to-face, 13 online) who all were recruited through online mediums. Results indicated that online counseling clients perceived a significantly stronger working alliance on the total Working Alliance Inventory-Short Form as well as the Goal subscale than did those who received face-to-face only counseling. No significant differences existed between the groups on general mental health or social presence. These results suggest that a more controlled study with a larger sample might find that a strong working alliance can be developed through online counseling.     

A Day at the Zoo Through the Lens of Jessica Benjamin's Bonds of Love

In this photo-based essay I bring Jessica Benjamin's project of transforming relationships of domination to a day at the zoo. The interrogation of the human/animal dualism illuminates relational moments of mutuality across species. Managing the tension between sameness and difference without collapse into hierarchical configuration, the human-animal connection may take its place in the project of transforming relationships of domination and extending the circle of ethical care.     

Social Workers’ Attitudes Toward Older Adults: A Review of the Literature

Ageist attitudes toward older adults have been recognized as barriers to recruiting and training competent social workers. This article provides a systematic review of the literature that focused on social workers’ and social work students’ attitudes toward older adults and working with older adults. The authors sought empirical studies that used an attitudinal measure of ageism with a social work sample, and a total of 20 articles met the criteria. Characteristics of the studies’ participants, methodology, instruments, and results were evaluated. This article discusses the findings and offers implications for future research.     

A Model for Change: Legislative Advocacy to Improving Access for the Uninsured and Underinsured in New York State 1

Advocates can successfully improve access to health care for people without health insurance. This article demonstrates the success of what began as a local advocacy effort to improve access to health care on Long Island, which later grew to become a major statewide advocacy movement. It explores the process taken by local coalition members to successfully fight for monumental public health legislation—first locally then statewide—to improve access to hospital care for the medically indigent. Using New York State as a model, it includes several approaches that could facilitate the enactment of legislation in other states. The experiences of New York advocates suggest that with focused collaborative efforts it is feasible to promote significant changes to public health laws to benefit the uninsured and underinsured.     

Developing intercultural competence and global citizenship through international experiences: academics’ perceptions

International education is a key priority for Australian universities, government and employer groups. For students, an international professional experience is uniquely placed in providing opportunities for developing intercultural learning, intercultural competence and global citizenship. Employers see graduates with international experiences as interculturally competent, viewing them as proficient in analysing and responding appropriately to culturally significant values and perceptions. This research seeks to understand how students are prepared for international experiences and how intercultural learning is integrated into course programmes. Academic staff responsible for international experiences were interviewed in one-on-one qualitative interviews about their practices and perceptions of preparing students for these experiences. Although all international programmes were procedurally well planned, we found that most participants did not include intercultural pedagogies into their programmes, nor did they purposefully seek to develop intercultural competence and global citizenship in their students. Professional development opportunities need to be created for academics to rethink their pedagogical intent regarding international experiences. Immersion in culture is not, on its own, an assurance of intercultural learning. Providing international experiences without a pedagogical framework that helps students to reflect on self and others can be a wasted opportunity and runs the risk of reinforcing stereotypical thinking and racist attitudes.     

A Review of: “Exploring Black Sexuality. By Robert Staples.”

Higgins, Trussell, Moore, and Davidson (2010) expand our understanding of sexual satisfaction by showing that first vaginal sex is more likely to be psychologically than physically satisfying and by revealing differences between women and men and similarities between African Americans and Whites. Their analyses highlight the need for further theory-building, explicating the dynamics of change over time, integrating qualitative and quantitative approaches, and articulating implications for public policy. These are crucial steps toward developing a social science of sexual satisfaction. More research that focuses on positive aspects of sexuality, such as satisfaction, should be encouraged.
