Predicting the Risk of Biological Invasions Using Environmental Similarity and Transport Network Connectedness

Understanding the risk of biological invasions associated with particular transport pathways and source regions is critical for implementing effective biosecurity management. This may require both a model for physical connectedness between regions, and a measure of environmental similarity, so as to quantify the potential for a species to be transported from a given region and to survive at a destination region. We present an analysis of integrated biosecurity risk into Australia, based on flights and shipping data from each global geopolitical region, and an adaptation of the “range bagging” method to determine environmental matching between regions. Here, we describe global patterns of environmental matching and highlight those regions with many physical connections. We classify patterns of global invasion risk (high to low) into Australian states and territories. We validate our analysis by comparison with global presence data for 844 phytophagous insect pest species, and produce a list of high‐risk species not previously known to be present in Australia. We determined that, of the insect pest species used for validation, the species most likely to be present in Australia were those also present in geopolitical regions with high transport connectivity to Australia, and those regions that were geographically close, and had similar environments.     

THE GREAT OVERESTIMATION: TAX DATA AND INEQUALITY MEASUREMENTS IN THE UNITED STATES, 1913–1943

Historical measures of income inequality in the United States must grapple with the challenge of data quality. We examine one such problem affecting the well-known estimates of income inequality produced by Piketty and Saez (2003) using the records of the Internal Revenue Service (IRS). Prior to 1943, incomes were self-reported. Combined with lax enforcement on the part of the IRS, self-reporting of incomes could provide a misleading portrait of the income distribution. To test the accuracy of IRS records, we compare them to independently tabulated state income tax returns between 1919 and 1945 from states with more comprehensive and rigorously enforced tax collection procedures. State income tax records show lower overall levels of income inequality than IRS records. However, we still find that top income concentrations declined across the period between 1929 and World War II. These findings attest to the sensitivity of distributional estimation to the reporting selectivity and economic quality of underlying tax data, suggesting that the existing IRS-derived series systematically overstates top-income concentration in the interwar period.

An Evaluation of Staff Preference for Graphic Characteristics

The purpose of the current study was to assess staff preference for how data were displayed on graphs. Specifically, preference for line versus bar graphs was assessed, as well as preference for data displayed as one date in time versus multiple dates showing performance trends. A secondary purpose of the study was to assess staff comprehension of the data presented across different graphic displays. Participants included 60 entry-level direct care staff and 25 seasoned therapists. Therapists had more advanced training in applied behavior analysis than the direct care staff. The vast majority of direct care staff preferred data depicted as a bar graph versus data depicted as a line graph, even preferring a single bar graph over a time-series line graph. The therapists preferred time-series line graphs to bar graphs. Most staff demonstrated understanding of the data, regardless of how it was depicted.     

‘What you need to do is …’: social work students’ reflections on an advice giving audit exercise

This paper reports on qualitative research investigating the advice giving behaviours of social work students. Second-year students, who were enrolled in an interpersonal communication skills course, were required to undertake an ‘advice-giving audit’ exercise across 6 days, with the aim of strengthening their awareness of the interactive nature of advice giving. Students then wrote a diary entry about the frequency of their everyday advice giving behaviour, its intent and reception. Nineteen students provided these reflections for analysis. Findings included three themes pertaining to advice-giving: (i) Giving advice as a natural, comfortable and unconscious way of communicating; (ii) Power and position influences advice dissemination, and (iii) Withholding advice opens, deepens and confuses norms of communication. A fourth theme pertained to the insights that students reported from engaging with the exercise. These findings illustrate the complex interactional process associated with professional advice giving. The research also suggests that experiential activities, which are conducted outside of the classroom, have significant potential to promote the critical examination of embedded communicative practices.     

Sexuality Examined Through the Lens of Attachment Theory: Attachment,Caregiving, and Sexual Satisfaction

Attachment researchers have proposed that the attachment, caregiving, and sexual behavioral systems are interrelated in adult love relationships (Mikulincer &; Shaver, 2007 Mikulincer , M. , &; Shaver , P. R. ( 2007 ). Attachment in adulthood: Structure, dynamics, and change . New York , NY : Guilford . [Google Scholar]). This study examined whether aspects of partners’ caregiving (proximity, sensitivity, control, compulsive caregiving) mediated the association between their attachment insecurities (anxiety and avoidance) and each other's sexual satisfaction in two samples of committed couples (Study 1: 126 cohabiting or married couples from the general community; Study 2: 55 clinically distressed couples). Partners completed the Experiences in Close Relationships measure (Brennan, Clark, &; Shaver, 1998 Brennan , K. A. , Clark , C. L. , &; Shaver , P. R. ( 1998 ). Self-report measurement of adult attachment: An integrative overview . In J. A. Simpson &; W. W. Rholes (Eds.), Attachment theory and close relationships (pp. 46 – 76 ). New York : Guilford .[Crossref] , [Google Scholar]), the Caregiving Questionnaire (Kunce &; Shaver, 1994 Kunce , L. J. , &; Shaver , P. R. ( 1994 ). An attachment-theoretical approach to caregiving in romantic relationships . In K. Bartholomew &; D. Perlman (Eds.), Advances in personal relationships (pp. 205 – 237 ). London : Kingsley . [Google Scholar]), and the Global Measure of Sexual Satisfaction (Lawrance &; Byers, 1998 Lawrance , K. , &; Byers , E. S. ( 1998 ). Interpersonal Exchange Model of Sexual Satisfaction Questionnaire . In C. M. Davis , W. L. Yarber , R. Bauserman , G. Schreer &; S. L. Davis (Eds.), Sexuality-related measures: A compendium (pp. 514 – 519 ). Thousand Oaks , CA : Sage . [Google Scholar]). Path analyses based on the actor-partner interdependence model (APIM) revealed that caregiving proximity mediated the association between low attachment avoidance and partners’ sexual satisfaction in distressed and nondistressed couples. Sensitivity mediated this association in nondistressed couples only. Control mediated the association between men's insecurities (attachment-related avoidance and anxiety) and their partners’ low sexual satisfaction in nondistressed couples. Attachment anxiety predicted compulsive caregiving, but this caregiving dimension was not a significant mediator. These results are discussed in light of attachment theory and their implications for treating distressed couples.     

Involvement in the Juvenile Justice System for African American Adolescents: Examining Associations with Behavioral Health Problems

While researchers have found that African American youth experience higher levels of juvenile justice involvement at every system level (arrest, sentencing, and incarceration) relative to their other ethnic counterparts, few studies have explored how juvenile justice involvement and number of contacts might be correlated with this broad range of problems. A convenience sample of 638 African American adolescents living in predominantly low-income, urban communities participated in a survey related to juvenile justice involvement. Major findings using logistic regression models indicated that adolescents who reported juvenile justice system involvement versus no involvement were 2.3 times as likely to report mental health problems, substance abuse, and delinquent or youth offending behaviors. Additional findings documented that the higher the number of juvenile justice system contacts, the higher the rates of delinquent behaviors, alcohol and marijuana use, sex while high on drugs, and commercial sex. These findings suggest that identifying and targeting youth who have multiple juvenile justice system contacts, especially those in low-resourced communities for early intervention services, may be beneficial. Future research should examine whether peer network norms might mediate the relationships between juvenile justice involvement and youth problem behaviors.     

Intensities of mobility: kinetic energy,commotion and qualities of supercommuting

This paper explores the intensities of long-distance commuting journeys in order to understand how bodily sensibilities become attuned to the regular mobilities which they undertake. More people are travelling farther to and from work than ever before, owing to a variety of factors which relate to complex social and geographical dynamics of transport, housing, lifestyle, and employment. Yet, the experiential dimensions of long-distance commuting have not received the attention that they deserve within research on mobilities. Drawing from fieldwork conducted in Australia, Canada, and Denmark this paper aims to further develop our collective understanding of the experiential particulars of long-distance workers or ‘supercommuters’. Rather than focusing on the extensive dimensions of mobilities that are implicated in broad social patterns and trends, our paper turns to the intensive dimensions of this experience for supercommuters by developing an understanding of embodied kinetic energy, commotion and quality. Exploring how experiences of supercommuters are constituted by a range of different material and bodily forces enables us to more sensitively consider the practical, technical, and affective implications of this increasingly prevalent yet underexplored travel practice.     

How do Australian adult mental health clinicians manage the challenges of working with parental mental illness? A phenomenological study

Adult mental health clinicians face a range of challenges that hinder their use of family‐focused practices when working with consumers who are parents. The purpose of this study was (a) to examine clinicians' experiences when working with parents and (b) identify strategies they found to be effective when working with parents. Eleven Australian mental health clinicians were recruited who regularly worked with consumers who are parents. Semistructured interviews were conducted within a qualitative paradigm and analysed using interpretative phenomenological analysis. Themes were identified which related to (a) managing sensitive parenting conversations, (b) making decisions about child safety in unclear or unpredictable situations, and (c) working with child protection services. Participants had developed strategies for managing the challenges of the first two practice issues and suggested organizational changes that could facilitate collaboration with child protection services. The findings highlight that the challenges of working with parents with mental health issues cannot be addressed with a one‐size‐fits‐all approach. Initiatives to facilitate the effective support of parents and their children need to be informed by contextual factors, including clinical practice.
