African Green Revolution,food sovereignty and constrained livelihood choice in Mozambique

This article examines the complicated food security agendas of the African Green Revolution and the food sovereignty models in Mozambique. Drawing on fieldwork conducted by the author in Mozambique in 2014 and 2015, the paper analyses how smallholder farmers engage with these two agrarian models. Whereas the literature frequently presents the African Green Revolution and the food sovereignty in oppositional frames, this paper finds that farmers in Mozambique utilize some of the tools that these models offer in complementary rather than competing ways. One such area is the use of commercial hybrid seeds and herbicides by some farmers associated with food sovereignty, an approach that runs counter to food sovereignty’s principles of agroecology. In Mozambique, farmers’ “lived experience” of food sovereignty is more a strategic response to their limited livelihood options, using whatever tools are available to them, rather than a resistance to power.     

Criminalising Academia: The Protection of State Information Bill and Academic Freedom

This article assesses the implications of the controversial Protection of State Information Bill for academic freedom in South Africa, specifically for communications, media and journalism studies. The Bill requires the security cluster to classify sensitive documents on national security grounds. Academic teaching and research can help citizens to understand whether the security cluster is acting in the universal interest, rather than the interest of a political elite; it can also be used to assess media performance in reporting on national security matters. Using a critical approach to the concept of national security, I argue that the Bill favours secrecy over openness, and South Africa’s embrace of the human security definition of national security has contributed to the problem. This overemphasis on secrecy is likely to reduce the few spaces that exist in academia for critical, emancipatory work on security issues, which could hobble the sector’s attempts to understand the deeper processes at work in the security cluster. If such enquiry is marginalised, then the higher education system risks becoming an instrument for continuity rather than change in South Africa’s existing, highly unequal power relations: relations that are being maintained increasingly by force.     

韩美同盟的现状:以战略同盟构想为中心

本文旨在以李明博政府的韩美战略同盟构想为中心,对韩美同盟的现状进行探讨。李明博政府正力图将现有韩美安保同盟发展为一揽子战略同盟,以此提升国力。由于面临着霸权的现实性局限,深感全球层面的同盟合作变得更加切合实际的美国奥巴马政府正在接受这一构想,但是对于具体的方案,两国的理解并不完全一致。而这一点正是本文的要旨之所在。     

非洲马瘟病毒VP7基因在重组杆状病毒中的表达及抗原性检测

利用pFastBacHTA质粒将非洲马瘟病毒(AHSV)血清4型的VP7基因重组入杆状病毒,并感染昆虫细胞Sf9。结果显示,VP7蛋白在真核细胞内获得了表达,但表达量较低。免疫印迹试验证实,VP7重组蛋白具有较好的免疫原性,将其作为检测抗原包被酶标板,初步建立了检测AHSV的间接酶联免疫吸附试验方法。

美国新政权与六方会谈前景探析

美国大选,执政八年的共和党政府结束了其历史使命,民主党奥巴马新政府建立.根据其上台前后的言行来看,美国奥巴马新政权的基本政策主要在于重振经济、结束伊战以及坚持反恐.在外交政策上,美国新政权将改变其前任布什政府初期的单边主义武力政策,更多地采取多边或双边的协调与合作政策.在朝鲜核问题以及六方会谈机制方面,虽然美国和朝鲜同为当事国,以及中国在其中也发挥了非常重要的作用,但是美国仍然握有相当的主动权.美国新政权的基本政策同样会延续布什政府后期利用六方会谈框架与朝鲜接触和谈判的政策,甚至会采取一些更积极的政策,因为奥巴马政权要解决其面临的内外难题,需要其盟国的协助,也需要中国等国家的协助,对朝鲜这样的国家也希望能够在国际压力下促使其和平地放弃核开发.当然,半岛无核化及防止核扩散仍然是美国的根本利益,要求朝鲜放弃核开发的目标不会有丝毫的改变,甚至从原则上来说美国新政权仍然没有承诺放弃使用武力.此外,美国新政权或者还仍然存在同中国和朝鲜之间在意识形态上的对立,但是,除非发生预料不到的突发事件,美国在朝核问题上使用武力的可能性极小,在意识形态上的某些不同也不会影响奥巴马政权务实灵活的现实主义政策.总之,美国新政权的基本政策有利于朝核问题的缓和,同样也有利于六方会谈持续发挥作用.虽然美国新政权有可能同朝鲜之间有更多的双边直接接触和谈判,但是不可能脱离六方会谈的框架,即或者两国的双边谈判在六方会谈框架范围内加以实现,或者彼此都需要六方会谈框架作为自己外交回旋的余地.作为美国新政权,虽然为了能够使朝核问题有所突破而有可能更加重视双边谈判,但考虑到同中俄的战略性关系以及同其盟国日韩的伙伴关系,也不可能弃六方会谈框架而不顾.     

Racial Socialization and Racial Identity: African American Parents’ Messages About Race as Precursors to Identity

This study uses two waves of data to examine the relationships among patterns of racial socialization experiences and racial identity in a sample of 358 African American adolescents (60% female and 40% male). Using latent class analyses, we identified three patterns of adolescent-reported racial socialization experiences: High Positive, Moderate Positive, and Low Frequency. Adolescent-reported racial socialization experiences at Wave 1 were associated with Wave 2 adolescent racial identity approximately one year later. Specifically, High Positive and Low Frequency racial socialization were associated with racial centrality, assimilationist ideology, and nationalist ideology. These findings suggest that various patterns of racial socialization practices play an important role in the developing significance and meaning that African American adolescents ascribe to race.

The Impact of Racial Discrimination and Coping Strategies on Internalizing Symptoms in African American Youth

The current study examined the impact of racial discrimination stress on internalizing symptoms and coping strategies in a sample of 268 African American early adolescents (mean age = 12.90; 56% female) from low-income communities. Information about discrimination stress, coping, and internalizing symptoms was obtained via adolescents’ self-report. It was predicted that discrimination stress would be positively associated with depression and anxiety, as well as culturally-specific coping. Finally, culturally-relevant coping and mainstream coping were examined as moderators of the association between discrimination stress and internalizing symptoms. Hierarchical regression analyses indicated that discrimination stress was positively associated with depression and anxiety and predicted culturally-relevant coping while controlling for mainstream coping. Communalistic coping moderated the association between discrimination and anxiety, but demonstrated a vulnerability function by increasing anxiety at high levels of discrimination. The results highlight the salience of racial discrimination for African American adolescents and the importance of considering culturally-specific coping behaviors.

Mother-Adolescent Language Proficiency and Adolescent Academic and Emotional Adjustment Among Chinese American Families

This study examined the role of adolescents’ and mothers’ self-reports of English and heritage language proficiency in youth’s academic and emotional adjustment among 444 Chinese American families. Adolescents who were proficient in English tended to exhibit higher reading achievement scores, math achievement scores, and overall GPA. Mothers who were English proficient tended to have children with higher academic achievement and fewer depressive symptoms. Results also indicated that adolescents’ heritage language maintenance was associated with positive adjustment, particularly amongst foreign-born youth and for youth whose parents were highly proficient in the heritage language. Mother-adolescent match in heritage language proficiency was related to higher math achievement scores and overall GPA. Additionally, higher heritage language proficiency was associated with fewer depressive symptoms for foreign-born but not U.S.-born youth. Overall, the findings suggest that proficiency in both the English and heritage language may confer advantages to Chinese American youth.

An American oil multinational in the U.K.: its formal review of industrial relations strategy

ABSTRACT

This paper is a case study chronicling and analyzing the strategic considerations given to industrial relations in a proposal to develop a coherent and deliberate strategy for industrial relations by the U.K. subsidiary of an American multinational oil company. The study is based on interviews and substantial internal documents provided by the case study managers. This represents a unique illustration as to the extent a major company goes through in considering the way in which it needs to consider industrial relations issues. Seldom has a document such as this been able to be analyzed by industrial relations researchers, and it illustrates the lack of strategic thinking, even in such a large sophisticated organization.
