This correction has no impact on any other result (neither theoretical nor empirical) provided in the above paper.     

不同烹调方法对食品营养素的影响

营养素是食品中重要养分,在烹调过程中,营养素也会发生改变。烹调通过增加色、香、味等,使食品更利于吸收,但烹调过程会破坏食品的一些营养素,而不同烹调方法对食品营养素的影响也不同。     

Is There a Causal Effect of Working Part‐Time on Current and Future Wages?

In this paper, I study the causal effects of part‐time work on current and future wages. To estimate these effects, I use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status. Exclusion restrictions from the institutional context are exploited to support identification. The results suggest that working part‐time with few hours has a large causal effect on current wages, but more extensive part‐time work does not reduce current wages. However, both types of part‐time work lead to negative long‐term wage effects.

Understanding conflicting perspectives in event planning and management using Q method

There is a need to better understand the interests of actors in the planning and management of major events. The diversity of actor perspectives about an event creates a wicked problem set that event organisers and public officials find difficult to understand, let alone address. This paper focuses on problem identification as one stage in the event planning and management process. It explores how problem structuring can contribute to more effective planning and management of actors' interests. The value of Q methodology is explored through a case study of the Australian World Rally Championship. Four perspectives are identified in the problem structuring process: the Skeptics, the Materialists, the Middle-grounders and the Supporters. The findings demonstrate that Q methodology is effective in identifying the depth and breadth of different problem perspectives, providing insights into the importance of different perspectives, and can be used reflexively to anticipate and manage potential conflict.     

The commercialisation of subsistence farms: Evidence from the new member states of the EU

For selected regions of five EU Member States (Bulgaria, Hungary, Poland, Romania and Slovenia), this paper examines the determinants of the commercialisation of (semi)subsistence farms. While subsistence farming has become an important feature of the EU, there is a lack of evidence on its spatial distribution, importance and reasons for persistence. The analysis utilises cross-regional survey data and qualitative interviews. Results suggest the absence of a subsistence poverty trap driven by either farmer perceptions or transactions costs although capital endowment appears to play a significant part. On the other hand the degree of market engagement depends on access costs, which vary with location, households’ productive assets, specialisation, and risk propensity. Implications for land use policy are discussed.

Building a better literature review: Looking at the nomological network of the country‐of‐origin effect

Due to a rising pace of knowledge production, reviewing extant knowledge on mature topics has become increasingly challenging. Researchers often need to account for hundreds of references with little guidance on how to proceed. Taking the phenomenon of the country‐of‐origin effect (COE) as an example, this paper proposes a solution to tackle this challenge. By adopting the principles of integrative literature reviews and using online databases, bibliography management software, and literature‐mapping techniques, I organize 355 papers about the COE. As a result, the nomological network of the COE is drawn while establishing links between the phenomenon, its antecedents, and its outcomes. This methodological article contributes to building better literature reviews. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.     

Constructive deviance as a driver for performance in retail

A growing body of research is concerned with deviance in the workplace. While much research has explored negative forms of deviance, we examine constructive deviance: behaviour that deviates from salient norms and benefits the reference group. We empirically explore manifestations, determinants and performance outcomes of constructive deviance in standardised work processes. We do this through a mixed-methods study in bakery trading departments of an Australian retailer. We illustrate that constructive deviance occurs in these settings and show that some manifestations of constructive deviance improve organisational performance and pave the way for applying constructive deviance as a strategic tool in retail.
