Conceptualizing anxiety among social work students: implications for social work education

Student anxiety is frequently discussed within social work education. Due to its potentially devastating impacts, social work educators need to have a full understanding of anxiety in this context, in order to determine the best way to support students. Research on student anxiety from a broad body of literature provides implications for social work classrooms and field education. Key underlying concepts from previous social work and related research on student anxiety inform a conceptual model to help educators develop a more complex understanding of student anxiety. Implications for further research and important next steps in the development of support strategies for social work students are identified.

An empirical assessment of the operational performance through internal benchmarking: a case of a global logistics firm

This article solves an operational performance measurement problem of a global logistics firm through an internal benchmarking tool. The intended impact is to enable logistics firms to form a deeper understanding of their own internal processes and metrics. The methodology of this in-depth action research involves a sequential approach with a series of interviews, questionnaire-based surveys, operations data collated through observations and process mapping yielding real-world data. A series of statistical tests are conducted to analyse the collated data. Strategic priorities of the firm are integrated with the firm’s operational performance to ascertain the effective performance by considering both the tangible and intangible measures. The outcomes inform both practitioners and academics how the firm could improve its freight forwarding business’s profitability by ensuring that its operations meet the prioritised criteria. The ‘best practice’ derived from internal benchmarking forms an intermediate step towards external benchmarking. The outcomes facilitate investigating the current business strategy, the standard operating procedures and the scope of improving those.

Dynamics of Domestic Labor Across Short‐ and Long‐Distance Family Relocations

Family relocations within developed countries are argued to have gendered consequences for paid employment, with men's careers improving and women's careers deteriorating. However, little is known about their potential relationships with outcomes in other life domains, including partnered men's and women's relative shares of domestic labor. The authors addressed this gap in knowledge by theorizing and examining how within‐couple gender gaps in domestic work evolve across short‐ and long‐distance family relocations over the life course, paying attention to the over‐time dynamics before and after event occurrence. To accomplish this, they used 12 years of panel data from the Household, Income and Labour Dynamics in Australia Survey and panel regression models. The results indicated that family relocations widen the within‐couple gender gap in weekly housework hours, largely because of shifts in women's employment situation and fertility episodes that accompany residential relocations.     

内部审计对反倾销会计信息证据效力的影响研究

从防范和应对的角度研究内部审计对反倾销会计信息证据效力的影响，有利于促进企业内部审计制度的发展和完善，提高反倾销会计信息证据效力，为我国企业的国际化战略提供有力支持。以2007-2012年间遭受反倾销诉讼的上市公司的数据为样本，检验了内部审计对反倾销会计信息证据效力的影响。实证结果显示：内部审计质量越高，企业应对反倾销的会计信息证据越有效力；内部审计质量一定的情况下，内部控制有效的企业，内部审计与内部控制的互动能够提高反倾销会计信息证据效力。
