Cultural adaptation and socialisation between Western buyers and Chinese suppliers: The formation of a hybrid culture

We aim to examine culturally-influenced behavioural adaptation embedded in socialisation processes at interfaces between Western buyers and Chinese suppliers in China. We conducted multiple case studies, including four cross-cultural partnerships, exploring how interface teams hosting trans-cultural boundary spanners at buyer-supplier interfaces socialise formally and informally and adapt behaviourally to three key cultural differences between Chinese Guanxi and the Anglo-Saxon form of Western culture. Data collected from 36 interviewees are used to explore the process of cultural behavioural adaptation and the emergence of a hybrid culture. We find that cultural adaptation is confined to those interface teams who interact routinely at the buyer-supplier interface and leads to the formation of a hybrid culture, which is a combination of Guanxi and western rules and procedures. The hybrid culture and cultural adaptation are two intermediary constructs between socialisation and relational capital, which enriches and explains this relationship in a cross-cultural context.

Perpetual securities and stock prices: Korean evidence

Perpetual securities are classified as equity under the International Financial Reporting Standards, but various contract terms embedded in the securities create additional debt- and equity-like characteristics. This study examines whether stock market investors differentiate between diverse contract attributes. Using quarterly data on listed non-financial firms in the Korea Exchange that issued perpetual securities during 2012–2020, we document the following findings. First, perpetual securities are positively associated with stock prices. Second, the positive association is driven by perpetual securities convertible to stocks rather than non-convertible ones. Third, when further decomposing convertible perpetual securities based on whether the conversion price is fixed or floating, only fixed-priced convertibles show a positive association with stock prices. Overall, our findings suggest that equity investors consider the detailed contract attributes important for financial instruments.     

从审美体验角度看旅游资源的美学价值评价

对于旅游资源的美学价值评价是旅游资源评价的重要组成部分,然而目前对旅游资源的美学评价却往往只重视旅游资源的形式美学价值,使得旅游资源美感质量评价有欠全面.针对这种情况,从旅游资源活动中旅游者的审美体验以及审美体验所达到的境界角度出发,详细分析不同类型的旅游活动中其审美体验与审美境界的差异,以及由此引起的对旅游资源美学价值评价的差别.在此基础上进一步提出了针对不同的旅游活动类型对旅游资源美学价值的要求,对旅游资源的美学价值,用整体综合和局部比较两种方法进行全面、准确地评价.     

Evolving Purchasing and Supply Organizations: A contingency model for structural alternatives

Purchasing and Supply Management (PSM) is under significant pressure to find levers to further increase its contribution to corporate goals. In order to improve performance in line with expectations, Purchasing and Supply Organizations (PSOs) have to evolve continuously. To help address this challenge, a comprehensive contingency framework of PSO structures is presented. The framework is based on existing literature on PSO contingency factors as well as analysis of two case companies. The findings highlight the importance of taking a contingency perspective for understanding the PSO and combining a detailed view of macro-level structural dimensions with micro-level characteristics. These macro-level dimensions comprise category, business unit, geography and activity. The micro-level characteristics comprise centralization, formalization, specialization, participation and standardization. From a theoretical perspective, the contingency framework opens up insights that can be leveraged in future studies in the fields of hybrid PSOs, global sourcing organizations, and International Purchasing Offices (IPOs). From a practical standpoint, an assessment of external and internal contingencies and their relation to specific structural dimensions and characteristics provides the opportunity for more consciously evolving the PSO to continue to improve PSM's contribution.     

Beyond the journey: the lasting impact of culinary tourism activities

In general, food tourism research has focused on tourist behaviour prior to or during trips, as well as food tourism development and marketing from a destination perspective. This exploratory study investigates food tourism from a broader context to determine if food tourism activities may impact attitudes and future behaviours. Data from a nine-country survey indicate that food activities likely impact trip satisfaction and influence intention to return and likelihood to recommend a destination. Food experiences are connected with memory, and these food experiences and souvenirs may influence destination image and lead to future purchases. Suggestions are provided for further research.     

Visitors’ memories of wildlife tourism: Implications for the design of powerful interpretive experiences

One of the aims of wildlife tourism is to educate visitors about the threats facing wildlife in general, and the actions needed to protect the environment and maintain biodiversity. To identify effective strategies to achieve this aim, this paper examines participants’ memories of their wildlife tourism experiences and explores processes through which such experiences can lead to long-term changes in conservation behaviour. Findings are based on 240 visitors’ extended open-ended responses to a follow-up web survey administered approximately four months after a visit to one of four marine-based wildlife tourism venues in Southeast Queensland. Qualitative analysis revealed four levels of visitor response to the experience, implying a process involving what visitors actually saw and heard (sensory impressions), what they felt (emotional affinity), thought (reflective response), and finally what they did about it (behavioural response). Recommendations are provided for ways tourism managers and wildlife interpreters can maintain and strengthen these dimensions of memorable experiences in order to enhance visitor satisfaction and encourage visitors’ long-term adoption of environmentally sustainable practices.
