保定地区不同动物源大肠杆菌氟苯尼考耐药基因flor的同源性分析

为了解不同动物间大肠杆菌的耐药性,对分离的23株鸡源、14株猪源和8株牛源大肠杆菌进行了耐药性测定,并对其氟苯尼考耐药基因flor进行了同源性分析。结果显示,同种动物之间、猪源与牛源flor基因的相似性为100%,鸡源与猪源、牛源flor基因的相似性为99.8%。与GenBank中已报道的flor基因(登录号AF231986)进行比对,鸡源flor基因在开放阅读框的第439,479,683位出现点突变,猪源、牛源flor基因在开放阅读框的第439,683,1100位出现点突变。由flor基因编码的氨基酸序列也发生了相应的改变。     

The ‘unwanteds’ and ‘non-compliants’: ‘unsupported mothers’ as ‘failures’ and agents in Australia’s migrant Holding Centres*

Abstract

Ideas of assimilated citizenship are inherently gendered and during Australia’s post-World War Two migration boom they were deeply and explicitly invested in marriage, children and domesticity. In this period of social conservatism and economic boom, assimilation rhetoric functioned as a reassuring mirror for the host population, promoting the dream of prosperous family life as the ultimate aspiration for refugees and migrants. The role of immigration Holding Centres within this vision was to provide a context in which migrants and refugees could take their first steps towards accomplishing this dream. These Centres of necessary temporary residence were designed as sites of transition towards autonomous, assimilated family life. However, those families headed by single mothers, often referred to in government records as ‘unsupported mothers’, had limited opportunities to live up to such images of assimilation, or even to comply with the economic imperatives of the migration scheme that had brought them to Australia. Based mainly on Department of Immigration records, this article demonstrates that despite recognising the long-term economic and social prospects their children represented, government agencies viewed many unsupported mothers as system failures. They attempted to remedy the situation by turning these women into live-in domestic workers, at times placing pressure on them to institutionalise their children in order to facilitate this, thereby prioritising their compliance with economic imperatives over support for their parenting. Within the limited scope of their agency, unsupported mothers responded by attempting to negotiate the terms of their compliance or simply refusing to comply. For the latter group, Holding Centres became a more permanent home. This permanence is read here as a gendered form of resistance to a system that struggled to foster their economic self-reliance without compromising their capacity to be mothers.     

毛圆科线虫对苯并咪唑类药物的抗药性

采用虫卵孵化试验对乌鲁木齐地区四个羊场饲养的羊感染的毛圆科线虫对苯并咪唑类药物的抗药性进行了检测.结果显示,两个南山羊场的虫卵孵化半数抑制度(ED50)分别为0.002和0.050μg/mL,两个屠宰场育肥羊场的ED50分别为0.270和0.293μg/mL,屠宰场育肥羊场的ED50远大于世界兽医寄生虫学促进协会推荐的0.100μg/mL.结果表明,该地区羊场存在抗苯并咪唑类药物的毛圆科线虫,而且抗药性程度较为严重.     

Enabling Middle Managers as Change Agents: Why Organisational Support Needs to Change

Change efforts frequently fail to achieve their desired outcome with failure often attributed to employee resistance to change. Literature on resistance indicates it can emerge from ineffective change management. This article argues that change management could be improved through middle managers actively undertaking a change intermediary role, thereby enabling employees to make sense of, and reframe, the change. Qualitative data is used to explore the extent to which middle managers had the capacity and support necessary to effectively implement change. The article concludes by proposing that managers who are actively engaged change agents, who frame and make sense of the change with employees, can reduce resistance. However, for this to be realised, organisations need to actively support the systematic development of middle management change management capabilities.     

A Mixed Methods Exploratory Examination of Victim Injury and Death: Effect of Weapon Type and Victim Resistance During Sexual Assaults by Strangers

Extending prior research regarding victim injury during sexual assault, the current study employed mixed-methods sequential explanatory research design to identify predictors of victim injury and victim death in 361 attempted and completed sexual assaults committed by 72 repeat sex offenders who assaulted strangers. Results from multinomial path analysis indicated that being female and offender coercion increased the likelihood of victim resistance, which in turn elevated the likelihood of victim injury. Divergent from the predictors of victim injury, the risk of victim death increased with victim age, offender alcohol use, and offender weapon possession. Exploratory analyses suggest that certain weapons resulted in higher probability of victim injury or victim death within the context of victim resistance. Exploratory analysis of qualitative data indicated that crime event order was not uniform—in some cases victim resistance preceded victim injury and in some assaults victim injury occurred prior to or was unrelated to victim resistance. The study findings highlight the need for further investigation of victim survival strategies when offenders possess different types of weapons.     

论群体性事件处置中参与者负性抵抗心理及其对策

Motivations for local resistance in international peacebuilding

This article discusses the complex motivations underlying local resistance to externally led post-war peacebuilding programmes. In examining the land distribution process in post-war Cambodia it proposes a five-part typology of motivations for the resistance that frequently appears in the context of international post-conflict peacebuilding processes. The article also argues that a single campaign of resistance is likely to involve multiple actors with multiple motivations.     

Politics at the margins: alternative sites of political involvement among young people in Cameroon

This paper analyses young people’s political discourses and experiences, highlighting their disillusionment with the postcolonial state. Drawing on ethnographic data and interviews with young people in the city of Bamenda, the article argues that young people’s perspectives and discourses on politics constitute alternative forms of political involvement and resistance. Their actions, inactions and discourses about politics and political personalities are informed by their specific identities and positionalities. However, taken collectively, these voices reveal current national anxieties about the postcolonial state whose legitimacy is widely believed to have eroded.

Labor control regimes and worker resistance in global supply chains

This article seeks to examine two inter-related dynamics, the relationship between the international dispersion of apparel production and labor control regimes, and the relationship between labor control regimes and patterns of worker resistance. The article argues that where apparel production has concentrated in the last decade has as much to do with labor control regimes as with wages and other economic factors. It suggests that there are three main labor control regimes in the sector: state control, market despotism, and employer repression. The article then argues that these systems of labor control are conducive to three patterns of worker resistance: wildcat strikes, international accords, and cross-border campaigns. The article explores these arguments by examining examples of apparel global supply chains in Vietnam, Bangladesh, and Honduras.
