Most measures have undergone rigorous development and psychometric testing, although none is both psychometrically and conceptually satisfactory. Empathy measures need to cover all relevant domains reflecting users' own perspectives and be tested with appropriate populations in relevant care settings.

Despite numerous tools being used in nursing research to assess empathy, there appears to be no consistency, suggesting the need to evaluate the rigour of empathy tools appropriately, either to inform education or for application in clinical settings.

Maize (Zea mays, L.) cultivation has expanded greatly from tropical to temperate zones; however, its sensitivity to chilling often results in decreased germination rates, weak seedlings with reduced survival rates, and eventually lower yields. We conducted germination tests on the maize-282-diverse-panel (282 inbred lines) under normal (25 °C) and chilling (8 °C) conditions. Three raw measurements of germination were recorded under each condition: 1) germination rate, 2) days to 50% germination, and 3) germination index. Three relative traits were derived as indicators of cold-tolerance. By using the 2,271,584 single nucleotide polymorphisms (SNPs) on the panel from previous studies, and genome-wide association studies by using FarmCPU R package to identify 17 genetic loci associated with cold tolerance. Seven associated SNPs hit directly on candidate genes; four SNPs were in high linkage disequilibrium with candidate genes within 366 kb. In total, 18 candidate genes were identified, including 10 candidate genes supported by previous QTL studies and five genes supported by previous gene cloning studies in maize, rice, and Arabidopsis. Three new candidate genes revealed by two associated SNPs were supported by both QTL analyses and gene cloning studies. These candidate genes and associated SNPs provide valuable resources for future studies to develop cold-tolerant maize varieties.

China is the most populated of any country in the world. Social norms and values pertaining to love and marriage have changed considerably since the launch of its open‐door policy and economic reforms of the 1980s. Attitudes to sex have become more open, while the negative consequences of early sexual intercourse have become issues of health and social concern. The aim of this study is to provide an overview of the teenage sexual attitudes and behaviour in contemporary China. A literature review was conducted between 2000 and 2010, using both English (Medline, CINAHL, PsycINFO, ASSIA) and Chinese language databases (China National Knowledge Infrastructure, Wanfang database). Thirty‐six studies were included and reviewed. It was found that young people reported poor sexual knowledge, especially in relation to reproductive matters and sexually transmitted infections. The media, such as television, magazines and the Internet, were seen as their main sources of information on sex. Despite the frequently reported liberal attitudes to sexual behaviour, only a small number of young people had already lost their virginity or been involved in pregnancies. Young men were more likely than young women to report having had sex, while respondents at vocational high schools were less likely to remain virgins than those at common/key high schools. Although the prevalence of sexual intercourse among Chinese teenagers was still lower than that reported in studies conducted in most western countries, the findings do reflect some changes in sexual values and behaviour of young people within the country. They also suggest the need to develop more comprehensive sex education programmes in co‐operation with young people, schools, health organisations, families and communities and to make sexual and reproductive health services accessible to teenagers and unmarried young people throughout China.

Antenatal screening has become standard practice in many countries. However, not all pregnant women choose to be tested. In the UK, the incidence of some birth defects is found to be higher in babies of Asian women than in those of women from other ethnic groups, while there is some evidence suggesting that ethnic minorities, especially Asian women, are less likely to undergo antenatal screening and prenatal diagnosis, the reasons for which are unclear. This study aims to identify and describe the literature on issues around antenatal screening and prenatal diagnostic testing for genetic disorders among women of Asian descent in western countries. The Medline, CINAHL, ASSIA and PsycInfo databases were searched for the period of 1995 and 2010. Twenty‐one studies met the inclusion criteria and were therefore reviewed. In general, Asian women were found to hold favourable attitudes towards testing. However, they reported a poorer understanding of testing than white women and not being offered a test, and were less able to make informed choices. Asian women in the UK and Australia were found to be less likely than their white counterparts to have undergone prenatal diagnosis, while such differences were not found in the USA and Canada. The equity of access to quality antenatal care, alongside comprehensive well thought out antenatal screening programmes, can be assured if strategies are in place which actively involve all ethnic groups and take account of social and cultural appropriateness for the population served. An understanding of broad factors that inform women’s decision‐making on test uptake would help health professionals provide women and their families with more culturally sensitive information and support that they may additionally need to make more informed choices.
