Main Producer

Kiwifruit (Actinidia spp.) is an economically substantial fruit crop with China the main producer. China is the primary source of wild kiwifruit and the largest producer of kiwifruit in terms of both production and planting area, and Shaanxi province is the largest kiwifruit producer in China. Previous studies reported presence of kiwifruit viruses in Actinidia chinensis. In this study, six viruses were identified in kiwifruit ‘Xuxiang’ (A. deliciosa) in Shaanxi, China. The incidence, distribution, and genetic diversity of these viruses were studied. The results showed that Actinidia virus A (AcVA), Actinidia virus B (AcVB), Actinidia chlorotic ringspot-associated virus (AcCRaV), cucumber mosaic virus (CMV), apple stem grooving virus (ASGV), and potato virus X (PVX) were the main viruses infecting Xuxiang kiwifruit in Shaanxi, China. Incidence of the various viruses with both single and multiple infection varied with different kiwifruit-growing counties. For single virus infection, the highest and the lowest numbers of samples infected were about 22 for AcCRaV and 0 for AcVB in Meixian out of 170 samples, 12 for AcVA and 0 for CMV in Zhouzhi out of 120 samples, 10 for AcVA and 0 for AcVB, AcCRaV, ASGV, PVX, and CMV in Yangling out of 70 samples, and 8 for AcCRaV and CMV and 0 for AcVA, AcVB, ASGV, and PVX in Hanzhong out of 80 samples, respectively. Samples which were multiply infected with two or more viruses were also detected. Analysis of the phylogenetic tree of these viruses showed some genetic variability in the AcVA, AcVB, and AcCRaV isolates of Shaanxi kiwifruit. There was no obvious molecular variation in the coat protein genes of ASGV, CMV, and PVX virus isolates from Shaanxi kiwifruit. The present study is the first large-scale survey of kiwifruit viruses in Shaanxi, China. To our knowledge, this is the first report of PVX infecting kiwifruit and the first report of molecular variability of AcVA, AcVB, and AcCRaV. These results provide important data for studying the genetic evolution of AcVA, AcVB, AcCRaV, ASGV, CMV, and PVX.

Corrective Information

Abstract Can corrective information change citizens’ misperceptions about immigrants and subsequently lead to favorable immigration opinions? While prior studies from the USA document how corrections about the size of minority populations fail to change citizens’ immigration-related opinions, they do not examine how other facts that speak to immigrants’ cultural or economic dependency rates can influence immigration policy opinions. To extend earlier work, we conducted a large-scale survey experiment fielded to a nationally representative sample of Danes. We randomly expose participants to information about non-Western immigrants’ (1) welfare dependency rate, (2) crime rate, and (3) proportion of the total population. We find that participants update their factual beliefs in light of correct information, but reinterpret the information in a highly selective fashion, ultimately failing to change their policy preferences.

- Analysis of poverty dynamics based on large-scale survey data shows that there is limited mobility across the income distribution for most individuals and families. Some people may get better-off over the lifecourse, as their careers develop and wages rise, but overall most poor people do not become very rich and most rich people do not become very poor. Lone parents are at high risk of poverty in the UK, but this poverty risk is reduced for those who are in employment and who receive state financial support through Tax Credits to supplement their wages. This article reports on longitudinal qualitative research which has involved repeat interviews with lone mothers and their children over a period of three to four years. The analysis here explores the experiences of sustaining employment while living on a low, but complex, income and highlights the challenges faced in seeking financial security in this context.

Work Integrated Learning

Across the globe, there are increased numbers of students undertaking university-level study in foreign countries. Many of the programs they enroll in include a workplace experience (also known as work integrated learning, internship, and/or practicum). The Work Placement for International Student Programs (WISP) project was conducted across Australia and aimed to identify current practices related to international students’ workplace experiences as well as develop resources to improve these experiences overall. This article focuses on an Australian large-scale survey ( n = 252) designed to explore international students perceptions of workplace experiences. Results showed that students rated overall workplace experience highly; however, their confidence in completing assessment items where reflection and self-evaluation were required was a concern. Students also rated self-perception of employability as uncertain despite having positive experiences in the workplace context. Findings showed that there is a need for universities to better support international students in completing reflective and self-evaluative assessment. In addition, more work needs to be done to improve confidence levels of international students around employability.
