Refugees’ dreams of the past, projected into the future

This article is about refugees’ and migrants’ dreams of home and family and stems from an Australian Research Council Linkage Grant, “A Hand Up: Disrupting the Communication of Intergenerational Welfare Dependency” (LP140100935), with Partner Organisation St Vincent de Paul Society (WA) Inc. (Vinnies). A Vinnies-supported refugee and migrant support centre was chosen as one of the hubs for interviewee recruitment, given that many refugee families experience persistent and chronic economic disadvantage. The de-identified name for the drop-in language-teaching and learning social facility is the Migrant and Refugee Homebase (MARH). At the time of the research, in 2018, refugee and forced migrant families from Syria, Iraq, and Afghanistan constituted MARH’s primary membership base. MARH provided English language classes alongside other educational and financial support. It could also organise provision of emergency food and was a conduit for furniture donated by Australian families. Crucially, MARH operated as a space in which members could come together to build shared community

Mindfulness, Stress Reactivity, and Depressive Symptoms Among “Third Culture Kids” in the United Arab Emirates

So called third culture kids (TCKs), the children and adolescents who accompany their parents on long-term overseas work assignments, often have to face life changes, cultural challenges and threats to social identity. The frequency, intensity and nature of these challenges arguably places some TCKs at heightened risk of stress-related mental health problems. Trait mindfulness, an attribute that can be enhanced through intervention, has been found to buffer against stress reactivity and common mental health problems. This study aims to explore the relationship between stress reactivity, trait mindfulness and depressive symptomatology among expatriate adolescents (TCKs) attending an international school in the United Arab Emirates (UAE). Participants included 230 high school students (57% female) from 45 different nations, with a mean age of 15.5 (±1.3, 12–19). Forty one percent had lived in the UAE for 7+ years. Participants completed measures of trait mindfulness, daily life stress reactivity, and depressive symptoms (CES-D). Mean depression score was high with 68.7% of TCK participants presenting as at risk of clinical depression. Lower stress-reactivity and greater trait mindfulness were associated with lower levels of depression; furthermore, low levels of trait mindfulness partially mediated the relationship between stress reactivity and depression. Efforts that aim to reduce stress reactivity and increase mindfulness might prove especially beneficial among the TCK population

Consumer insights and the importance of competitiveness Factors for mature and developing destinations

This article aims to understand the importance of various destination attributes to the competitiveness of tourism destinations from a consumer perspective, while at the same time contrasting these in a mature versus developing destination. A sample of Australian-based domestic tourists were surveyed to assess the relative importance of tourism destination competitiveness (TDC) attributes in the context of developing and mature destinations. This research firstly appears to verify that the importance of many TDC elements, highlighted by consumers, is not dissimilar from other stakeholder-based TDC studies. Furthermore, this research effort established that in terms of attribute performance, relative destination immaturity may well constrain a developing destination’s ability to satisfy the needs of consumers

Sustained inhibition of rat myometrial gap junctions and contractions by lindane

BACKGROUND: Gap junctions increase in size and abundance coincident with parturition, forming an intercellular communication network that permits the uterus to develop the forceful, coordinated contractions necessary for delivery of the fetus. Lindane, a pesticide used in the human and veterinary treatment of scabies and lice as well as in agricultural applications, inhibits uterine contractions in vitro, inhibits myometrial gap junctions, and has been associated with prolonged gestation length in rats. The aim of the present study was to investigate whether brief exposures to lindane would elicit sustained inhibition of rat uterine contractile activity and myometrial gap junction intercellular communication. METHODS: To examine effects on uterine contraction, longitudinal uterine strips isolated from late gestation (day 20) rats were exposed to lindane in muscle baths and monitored for changes in spontaneous phasic contractions during and after exposure to lindane. Lucifer yellow dye transfer between myometrial cells in culture was used to monitor gap junction intercellular communication. RESULTS: During a 1-h exposure, 10 micro M and 100 micro M lindane decreased peak force and frequency of uterine contraction but 1 micro M lindane did not. After removal of the exposure buffer, contraction force remained significantly depressed in uterine strips exposed to 100 micro M lindane, returning to less than 50% basal levels 5 h after cessation of lindane exposure. In cultured myometrial myocytes, significant sustained inhibition of Lucifer yellow dye transfer was observed 24 h after lindane exposures as brief as 10 min and as low as 0.1 micro M lindane. CONCLUSION: Brief in vitro exposures to lindane have long-term effects on myometrial functions that are necessary for parturition, inhibiting spontaneous phasic contractions in late gestation rat uterus and gap junction intercellular communication in myometrial cell cultures
