From fighting to freedom: Stories from Serbian Balkan war refugees

The 1990s saw the dissolution of former Yugoslavia following the decline of Communism. Ethnic cleansing campaigns resulted in the displacement of many of the region’s citizens. There is limited published research which specifically examines Serbian experiences of trauma and transformation as a result of the civil unrest. The lack of research attention that this population has received was likely influenced by the international mass media reporting of the events during this time, which portrayed the Serbs as the sole transgressors of the ethnically-driven conflicts. This qualitative study involved ten Serbian participants who migrated to Australia as a result of the Balkan conflicts of the 1990s. Through multiple semi-structured interviews with participants, eight stories were produced, where three participants co-constructed their stories. Six of these stories have been selected for presentation in this book. In analysing the interview data, eight key themes were identified. These were: changing conceptions of ethnicity; the role played by wider social networks; the importance of family throughout participants’ lives; the impact of war experiences; the experiences and impact of health difficulties; the role of grief and loss; the importance of age in shaping participants’ experiences and responses to trauma; and the importance of lifelong learning. In considering these themes, three adaptation patterns – active integration, passive integration, and segregation – were developed and are specific to the participants in the study.https://research.acer.edu.au/saier/1021/thumbnail.jp

Social Work Faculty Perceptions of the Leadership Qualities of Their Academic Leaders

Leadership within the social work academic setting is unique and complex. Understanding the way in which faculty members experience the leadership qualities of their academic leaders is a necessary precursor to effective leadership development. This article reports on the quantitative data from a mixed-methods, nationwide survey exploring social work faculty perceptions of the leadership qualities of their academic programs\u27 leaders

Punish Them or Engage Them? Teachers’ Views of Unproductive Student Behaviours in the Classroom

This paper reports on a study that investigated the extent to which student behaviour is a concern for school teachers. A questionnaire was used to investigate teachers’ views about student behaviour in their classes. The results suggest that low-level disruptive and disengaged student behaviours occur frequently and teachers find them difficult to manage. Aggressive and anti-social behaviours occur infrequently. Teachers employ strategies to manage unproductive behaviours that locate the problem with the student. This paper argues that teachers could benefit from understanding how the classroom ecology influences engagement and therefore student behaviour, rather than focusing on ‘fixing’ unproductive behaviour

Cellular Basis of Potato Spindle Tuber Viroid Systemic Movement

AbstractViroids are small, nontranslatable pathogenic RNAs that replicate autonomously and traffic systemically in their host plants. We have used in situ hybridization to analyze the trafficking pattern of Potato spindle tuber viroid (PSTVd) in tomato and Nicotiana benthamiana. When PSTVd was inoculated onto the stem of a plant, it replicated and trafficked to sink, but not source, leaves. PSTVd was absent from shoot apical meristems. In the flowers of infected plants, PSTVd was present in the sepals, but was absent in the petals, stamens, and ovary. The replicative form of PSTVd was detected in the phloem. Our data demonstrate that (i) PSTVd traffics long distance in the phloem and this trafficking is likely sustained by replication of the viroid in the phloem, and (ii) PSTVd trafficking is governed by plant developmental and cellular factors. The dependency of PSTVd and other viroids on cellular mechanisms for RNA trafficking makes them excellent tools to study such mechanisms

"In the eye of the beholder...": Girls', boys' and teachers' perceptions of boys' aggression to girls

Because children and young teenagers usually associate in same-sex groups, psychological research concerned with adolescent aggression has often concentrated on within-sex relationships. However, during adolescence, boys and girls increasingly interact socially. This paper reports a study of boy-to-girl aggression as perceived by girls, boys and their teachers. Focus group discussions were conducted with groups of Grade 9 adolescents (aged between 14 and 15 years) across four middle class schools in metropolitan Adelaide, South Australia, and individual interviews were conducted with their teachers. Thematic analyses revealed different understandings by girls, boys and teachers of the same behaviour. Girls and teachers reported that boys frequently use verbally offensive language including sexual harassment toward girls but boys argued that they were often not being malicious but rather just joking and that girls over-reacted. Girls, boys and teachers agreed that boys often harassed girls in order to impress other boys and for their own entertainment or fun. Teachers also emphasised home and cultural background factors in influencing boys' behaviour toward girls. All three groups agreed that boys' behaviour toward girls could have devastating effects on the girl victims. Girls' appearance was reported as a major contributing factor associated with boys' victimisation such that, while physical attractiveness could protect a girl from boys' meanness, over-weight girls or those seen as being unattractive or 'uncool' were vulnerable. However, girls were not seen universally as passive victims. Girls, boys and teachers reported that many girls responded assertively and even matched boys' aggression. Girls and boys agreed that teacher intervention was often not helpful. In contrast, teachers reported the effectiveness of school anti-harassment policies and a range of successful interventions. This study highlights the importance of understanding behaviour from different perspectives and confirms research that emphasises the crucial role of the peer group in influencing aggressive interactions among students in schools. © 2005 Shannon Research Press.C

Thallium-isotopic compositions of euxinic sediments as a proxy for global manganese-oxide burial

The definitive version was published in Geochimica et Cosmochimica Acta 213 (2017): 291-307, doi:10.1016/j.gca.2017.06.041.Thallium (Tl) isotopes are a new and potentially powerful paleoredox proxy that may track bottom water oxygen conditions based on the global burial flux of manganese oxides. Thallium has a residence time of ~20 thousand years, which is longer than the ocean mixing time, and it has been inferred that modern oxic seawater is conservative with respect to both concentration and isotopes. Marine sources of Tl have nearly identical isotopic values. Therefore, the Tl sinks, adsorption onto manganese oxides and low temperature oceanic crust alteration (the dominant seawater output), are the primary controls of the seawater isotopic composition. For relatively short-term, ~million years, redox events it is reasonable to assume that the dominant mechanism that alters the Tl isotopic composition of seawater is associated with manganese oxide burial because large variability in low temperature ocean crust alteration is controlled by long-term, multi-million years, average ocean crust production rates. This study presents new Tl isotope data for an open ocean transect in the South Atlantic, and depth transects for two euxinic basins (anoxic and free sulfide in the water column), the Cariaco Basin and Black Sea. The Tl isotopic signature of open ocean seawater in the South Atlantic was found to be homogeneous with ε205Tl = -6.0 ± 0.3 (± 2 SD, n = 41) while oxic waters from Cariaco and the Black Sea are -5.6 and -2.2, respectively. Combined with existing data from the Pacific and Arctic Oceans, our Atlantic data establish the conservatism of Tl isotopes in the global ocean. In contrast, partially- and predominantly-restricted basins reveal Tl isotope differences that vary between open-ocean (-6) and continental material (-2) ε205Tl, scaling with the degree of restriction. Regardless of the differences between basins, Tl is quantitatively removed from their euxinic waters below the chemocline. The burial of Tl in euxinic sediments is estimated to be an order of magnitude less than each of the modern ocean outputs and imparts no isotopic fractionation. Thallium removal into pyrite appears to be associated with a small negative fractionation between -1 and -3 ε205Tl, which renders Tl-depleted waters below the chemocline enriched in isotopically-heavy Tl. Due to the quantitative removal of Tl from euxinic seawater, Tl isotope analyses of the authigenic fraction of underlying euxinic sediments from both the Black Sea and Cariaco Basin capture the Tl isotope value of the oxic portion of their respective water column with no net isotope fractionation. Since the Tl isotope composition of seawater is largely dictated by the relative fraction of Mn-oxide burial versus oceanic crust alteration, we contend that the Tl isotope composition of authigenic Tl in black shales, deposited under euxinic conditions but well-connected to the open ocean, can be utilized to reconstruct the Tl isotope composition of seawater, and thus to reconstruct the global history of Mn-oxide burial.JDO and SGN would like to thank NSF and NASA for funding; JDO and TJH gratefully acknowledges support from the Agouron Institute Postdoctoral Fellowship Program

Caliche Soils as a Filter Medium for Treatment and Disposal of Wastewater

Through support from the Texas On-Site Wastewater Treatment Research Council, a project to search the literature relative to caliche materials as a medium for treatment and disposal of wastewater has been conducted. It was hypothesized before undertaking this effort that there would be a dearth of published and unpublished information on this subject. Specifically, the goals of the project were to: Provide a working definition of “caliche” in relation to treatment of wastewater. Perform a comprehensive literature review on the effectiveness of caliche soils as a bioremediation filter media in the treatment and disposal of wastewater. Develop recommendations for future research that would address issues identified above

Crystal Structure of Monoclonal 6B5 Fab Complexed with Phencyclidine

The crystal structure of monoclonal antibody (mAb) 6B5 Fab fragment complexed with 1-(1-phenylcyclohexyl)piperidine (PCP or phencyclidine) was determined at 2.2-A resolution. 6B5 was originally produced from a mouse immunized with a phencyclidine analogue hapten 5-[N-(1'phenylcyclohexyl)amino]pentanoic acid conjugated to bovine serum albumin. This mAb was selected for further study because of its high affinity (Kd = 2 x 10(-9) M/liter) for PCP and usefulness in reversing PCP-induced central nervous system toxicity in laboratory animals. The dominant feature of the 6B5 Fab.PCP complex is the deep binding site and hydrophobic nature of the interaction. The ligand binding pocket of 6B5 Fab has numerous aromatic side chains, as compared with other known Fab structures. The most notable feature of the binding site is a Trp at position 97H (H-chain), and the side chain of this residue appears to act as a hydrophobic umbrella on the ligand in the antigen binding pocket. There are only two other known Fabs found with a Trp at the 97H position in complementarity determining region (CDR) H3, but they do not play a major role in the interaction with their respective antigens; in both Fab TE33 and R6.5 the Trp 97H side chain is positioned away from the bound antigen. Comparison of the CDR residues of 6B5 with other Fab structures with similar CDR sizes and amino acid compositions reveals a number of important patterns of residue substitutions that appear to be critical for specific PCP ligand interactions
