Generalized minimum aberration mixed-level orthogonal arrays: A general approach based on sequential integer quadratically constrained quadratic programming

Orthogonal fractional factorial designs and in particular orthogonal arrays (OAs) are frequently used in many fields of application, including medicine, engineering, and agriculture. In this article, we present a methodology and an algorithm to find an OA, of given size and strength, which satisfies the generalized minimum aberration criterion. The methodology is based on the joint use of polynomial counting functions, complex coding of levels, and algorithms for quadratic optimization and puts no restriction on the number of levels of each factor.     

Accommodating ‘foreigners’: narrative accounts of Berlin's German-born Turkish Ausländer

This paper examines the discursive messages conveyed through everyday encounters among German-born Turkish Ausländer (foreigners) and ethnic Germans in Berlin. Using narrative analysis, I explore how these messages operate to maintain a series of separate and unequal social relations based on gender, ethnicity, religion, and skin colour. The personal experiences of local residents illustrate how these discourses serve to mark some Ausländer as less threatening than others, some as preferable, and others as undesirable. Some Ausländer are also considered more valuable than others, and the status of one often depends on the superior or subordinate status of the other. Through exploring these complexities as experienced by local informants, this paper shows the importance of certain interactive processes that construct Ausländerness in varying ways, while still defining people's identities in relation to norms that privilege the dominant subjects.     

Love is Not All You Need: A Revolutionary Approach to Parental Abuse

This case story is a composite of similar family situations where the parents were at risk of harm from their teenage children and commonly the father/step‐father has moved out of home leaving the mother to parent the children on her own. Several of these cases involved physical threats to the lives of the parents. These referrals occurred in a Child, Adolescent and Family Mental Health Service and a Family Therapy NGO between 1985 and 2005. This approach is offered as a complement to the widely published ‘non‐violent resistance’ approach of Haim Omer and his colleagues. We hope it goes some way to address what Lavi‐Lavavi et al ( 2013 , Journal of Systemic Therapies, 32(4), 79–93). describe as ‘the mother's plight’:

The plight of the mother continues to present a major challenge… We are also seeking ways to allow the mother more breathing space, help her to disengage from abrasive conflicts, acknowledge her contribution and sacrifice, and provide her with vantage points that may help her recognize and enhance small improvements. Hopefully, these measures will enable women to evolve from unacknowledged victims to pillars of the family’ (p. 92).

     

ACHIEVING REFLEXIVITY: MOVING RESEARCHERS FROM ANALYSIS TO INTERPRETATION IN COLLABORATIVE INQUIRY

The idea of ‘teaching’ reflexivity might seem to some to be a nonsense but many students, both undergraduate and postgraduate, struggle with ‘it’ as a concept, a process and as a means of moving away from simplistic themed research categories towards in‐depth interpretation. This paper will examine the nature of reflexivity from the perspective of a personal stance and suggest the use of particular strategies for interpreting data reflexively. Such strategies include the use of biographical accounts and organising principles, the exploration of metaphor and metonymy and the utilisation of poetry as an interpretative device. It will offer particular ways of undertaking reflexive interpretation that have been used successfully with many postgraduate students and researchers.     

I'm Not a Bad Mother — Stories of Mothering‐on‐the‐Edge

This article is located in the field of custody and day‐to‐day care, with a focus on experiences of mothering where mothers no longer have everyday care of their children. At the time of writing, tens of thousands of mothers live separately from their children in Aotearoa, New Zealand. However, there is a general perception of rarity associated with non‐resident mothers, partly due to their reluctance to speak of loss of custody. In this article, we develop a theoretical discussion around the inside/outside relationships between non‐resident mothers and their children that informs therapeutic practice. We argue that mothers who live apart from their children are situated at the edge or periphery of their children's day‐to‐day lives and experience this as outside the lives of their children. Nevertheless, mothers' stories speak of qualities of (m)othering that have been born of and nurtured by longstanding and long‐term commitment to their children.     

Narratives from the neighbourhood: The discursive construction of integration problems in talkback radio1

This paper examines how speakers deploy narrative devices in talking about Sudanese refugees. Particularly, we show how narrative constructions form an important basis for the advancement of accounts about integration problems into the local polity. We analyse talkback ‘phone‐in’ calls to a local Adelaide radio station that provide callers an opportunity to give accounts of events and social phenomena that concern them in their local settings. Analysis shows that speakers regularly deployed narrative constructions, first‐hand ‘witnessing’ devices that functioned to legitimate accounts as veridical versions of events, and contrast devices to explicate the moral and behavioural aberrance of Sudanese refugees. The analysis illustrates how these discursive devices function rhetorically in interaction, in ways that differentiate Sudanese refugees as problematic. Through this analysis, we contend that narrative devices precipitate and bolster socio‐political policies that have serious, negative consequences for Sudanese refugees.     

Trauma management: Chernobyl in Belarus and Ukraine

Although the Chernobyl nuclear disaster happened in the Soviet Union in 1986, we still do not know how the most affected states – Ukraine and Belarus – have managed this tragedy since independence. Drawing on the concept of cultural trauma, this article compares Chernobyl narratives in Belarus and Ukraine over the past 28 years. It shows that national narratives of Chernobyl differ, representing the varying ways in which the state overcomes trauma. Our understanding of post‐communist transformations can be improved by analysing trauma management narratives and their importance for new national identity construction. These narratives also bring new insights to our vision of cultural trauma by linking it to ontological insecurity. The article demonstrates how the state can become an arena of trauma process as it commands material and symbolic resources to deal with trauma. In general, it contributes to a better understanding of how the same traumatic event can become a source of solidarity in one community, but a source of hostility in another.     

Negotiating Illness in Medical Interactions: Narrative Styles of two Children with Leukaemia

The illness narratives presented in this paper were video‐recorded as part of child patient–staff interaction, during more than a year of ethnographic fieldwork at a paediatric oncology centre. The two children tended to ‘do illness’ differently, producing different types of narrative accounts. One of them presented accounts that invoked ‘fight’ metaphors, whereas the other one invoked patient identities. Also, the medical staff deployed different interactional strategies with different children in response to their narrative constructions of themselves and their leukaemia.     

城市多元生鲜市场空间格局的演变及其相互关联——以昆明主城区为例

生鲜市场关系到民生、城乡经济联系和就业等问题,孤立地研究某一类型的生鲜市场具有片面性,不利于理解整个城市的生鲜市场功能和全局管理。通过对昆明市主城区各种生鲜市场实地调查和问卷,运用ArcGIS空间叠加分析、核密度分析和统计分析等多种方法描述了该城市多元生鲜市场的空间格局的形成和演变,归纳不同生鲜市场的特征及其多元生鲜市场共存格局的原因,并对未来演变趋势进行分析,提出此消彼长的互动关联性对各主体所隐含的机遇和挑战,由此说明从地域视角开展的研究,能综合把握全局特征,以及各类型之间的彼此关联性,可弥补以往单一类型研究的不足,并对政府的相关决策进行讨论。
