Ethical challenges in conducting research with hard to reach families

This paper reflects on some of the ethical challenges encountered by the authors whilst undertaking sensitive qualitative research with parents and children who are traditionally hard to reach. The research aimed to provide more holistic and in‐depth accounts of parenting on a low income in diverse social circumstances than already exist. The nature of the sample and the subject matter that was covered inevitably raised many familiar ethical dilemmas and some that are less often encountered in practice, particularly in relation to child protection. In this article we discuss our approach to ethics, some of the ethical challenges we encountered undertaking work with families and discuss the complexity of decision‐making around risk of harm to children. We conclude that a clear framework to avoid harm should be developed at the outset and a transparent approach to child protection issues should be used. Additional time and resources need to be incorporated at the planning stage of similar projects in order to develop appropriate methods, ensure effective decision‐making and support researchers.

To Check In or Not to Check In? That Is the Question!

The University of South Florida Tampa Library discontinued checking in print journals and periodicals for a trial period of one year from July 2005 to June 2006. This article discusses the reasons behind such a decision, the challenges, and final results. Though the trial proved inconvenient for public and technical services alike, few specific problems were reported via e-mail, online forms or in person. The library derived several benefits from this project, particularly in terms of the timing, since it happened just as the library moved to a new integrated library system, from NOTIS to Aleph.     

Defining Nations in Asia and Europe: A Comparative Analysis of Ethnic Return Migration Policy1

We argue that regional comparison of East Asian and European ethnic return migration policy offers important new perspectives on nationhood, nondiscrimination norms, and trans‐nationality. We find that despite international nondiscrimination norms, preferential ethnic return policy is common in both regions. These policies at least implicitly define the nation as existing across borders. However, there are significant regional differences. East Asian states use co‐ethnic preferences instrumentally for economic goals and also offer preferential treatment of co‐ethnic foreign investors. European states offer preferences to coethnics to protect these populations or express symbolic ties, sometimes at great expense. Thus, in Europe the state has an obligation to assist coethnics abroad, but in Asia, foreign coethnics assist the state.     

中国城市群基本概念的再认知

城市群并不是孤立封闭的体系,它是与邻近区域内、特别是经济发达的城镇密集区的特定区域范围内不同规模的城市(镇)有着密切联系,依托优越的自然环境基础和发达的交通运输体系以及信息网络形成的一个比较完整的有机整体。尤其是在全球经济一体化以及新型城镇化的新形势下,城市群区内每一个城市均发挥着区域经济增长点和城市功能的特殊作用,并依托城乡一体化区域发挥着强大的辐射作用(包括集聚与疏散作用)。本文在这一基础上深入分析了中国城市群是由城镇化高度发育而形成这一动力问题;论证城市群与城镇密集区的相似性,并对我国城市群范围的识别标准和城市群基本概念的再认识,比较完整地概括了当前我国城市群研究动态与阶段性成果,以供我国城市地理与经济学工作者参考,以便更加深入地研究中国城市群的特有现象和各类问题。     

Contested news values and media performance during the Umbrella Movement

Social crises are a huge challenge to the performance of the media. The norms and routines of news making with which journalists comply can become problematic in the context of intensive public sentiment and empathy. News values, including the sacred belief in objective reporting, are questioned in the light of controversies over editorial judgment within and outside the newsroom. I examine the contested news values that manifested in the Umbrella Movement of Hong Kong in 2014. In particular, I focus on the arguments and deliberations regarding news objectivity, which involved several parameters of the performance of the media during this social crisis.     

Creating Tactile Space during a University Extension Field Day Event: The Case of a Sustainable Agriculture Innovation

Drawing on the concept of “tactile space,” we evaluate the experiential learning environment of a university extension field day event focused on a sustainable agriculture innovation: biodegradable plastic mulch. Introduced by sociologist Michael Carolan, “tactile spaces” are sensuously rich learning environments where participants interact with each other and the environment in an “embodied” and “embedded” manner leading to long‐lasting attitudinal and behavioral change. In our study, farmers, extension professionals, crop consultants, and mulch manufacturers participated in a field day event designed to provide both embodied and embedded experiences in an effort to stimulate interest in biodegradable plastic mulch, an economically and environmentally sustainable alternative to polyethylene mulch. Field day participants engaged in hands‐on demonstrations preceded and followed by focus group sessions. Enhancing the learning environment in these ways improved the success of the field day event by encouraging practice‐based forms of learning, which supplemented and reinforced the claims made about biodegradable plastic mulch. However, the tactile space could have been enriched by providing more opportunities for participants to become embedded within the environment, and by adding elements to overcome the temporal limitations of the field day event. This research contributes to the broader literature on participatory research and extension.     

Hedging Barrier Options in GARCH Models with Transaction Costs

This study proposes a modified strike‐spread method for hedging barrier options in generalized autoregressive conditional heteroskedasticity (GARCH) models with transaction costs. A simulation study was conducted to investigate the hedging performance of the proposed method in comparison with several well‐known static methods for hedging barrier options. An accurate, easy‐to‐implement and fast scheme for generating the first passage time under the GARCH framework which enhances the accuracy and efficiency of the simulation is also proposed. Simulation results and an empirical study using real data indicate that the proposed approach has a promising performance for hedging barrier options in GARCH models when transaction costs are taken into consideration.
