International involvement of established SMEs: A systematic review of antecedents,outcomes and moderators

This article seeks to review the present state of research on established SME's international involvement. Based on a literature review of 121 articles, we develop an integrative framework that examines the antecedents, outcomes and moderators of SME international involvement. We critically assess and examine how the literature has evolved over the last three decades. Particular attention is paid to discussing the main findings, theoretical and methodological inconsistencies, and to providing suggestions for future research. The review reveals that while international involvement research has made considerable progress over the last few years, its advances have been uneven and leave important areas of research unexplored.     

Why are you so tolerant? Towards the relationship between consumer expectations and level of involvement

It is vital that managers understand the way consumers form their expectations so that quality services are offered. Therefore, the aim of the paper is to assess the behaviour of consumer expectations over time and what effect does the level of involvement have on them. Two field studies are realized with students from an educational institution under the perspective of cluster analysis and latent growth model. Our results reveal that the patterns of expectations change from one service meeting to another and these mutations can be explained by the degree of consumer involvement. As theoretical insights, in addition to broadening the debate about the antecedents of expectations, this study also reaffirms the dynamic behaviour of consumer expectations. Thus, the constant control of expectations shows a relevant strategic way for survival in competitive sectors.     

水下降水关键技术的研究与应用

为了降低水体下土层中的水位或水压，拟采用一种非常规的水下降水技术，保证水下工程的安全。水下降水技术是一种全新的技术，和陆上降水相比，其技术环节更复杂、施工难度更大。通过对某工程在水下降水施工过程中的技术难点、可行性分析、设计计算、土层参数确定等环节的探索、研究，并采用止水套管技术、新型隔水材料、水下降水试验模型、套管稳定性分析等一系列创新技术，建立一套可行的水下降水技术方案，确保该工程安全、顺利完成。水下降水技术在该工程的应用为国内外首次，但水下降水施工难度大、费用高，还存在一定的技术风险，还有一些技术环节需要进一步探讨。     

Does oil price variability affect the long memory and weak form efficiency of stock markets in top oil producers and oil Consumers? Evidence from an asymmetric MF-DFA approach

This study examines the asymmetric multifractality and the market efficiency of the stock markets in the countries that are the top crude oil producers (USA, KSA, Canada and Russia) and consumers (Brazil, China, India, and Japan) using an asymmetric multifractal detrended fluctuation analysis (A-MF-DFA) method. The results show evidence of an asymmetric multifractal nature for all markets. Moreover, the multifractality is stronger in the upward movement of the market returns, except in China. The degree of efficiency of the stock markets is shown to be time-varying and experienced a decrease during the 2008 global financial crisis (GFC), but an upside trend occurred during the recent oil price crash followed a significant decline during COVID-19. The stock markets have an anti-persistent feature during GFC and COVID-19, whereas they exhibit a long-term persistent feature during oil price crash. More interestingly, the efficiency of the stock markets of crude oil producers is lower in general than that of oil consumers. Furthermore, the efficiency of the stock market is lower in the downward movement of the market returns than in the upward movement. Asymmetry and oil price uncertainty index are the key driver of the stock markets and can serve as predictor of the stock market dynamics of top oil producers and top oil consumers particularly during COVID-19 and oil price crash.     

Pollution Havens and Their Relationship to the Environmental Kuznets Curve: The Case of the us Tyre Industry

The Environmental Kuznets Curve hypothesis suggests that, as a country's national income grows, environmental degradation subsides as the population demands a cleaner environment. On the other hand, critics of the Environmental Kuznets Curve claim that many polluting industries simply relocate offshore, where environmental compliance is less costly. They then export their products back to their previous home countries. This is known as the Pollution Haven hypothesis. This article demonstrates how pollution havens can falsely give the appearance of an Environmental Kuznets Curve by analysing lead emissions from the US automotive tyre manufacturing industry.     

When do product architectures mirror organisational architectures? The combined role of product complexity and the rate of technological change

In the modularity literature, an architectural decomposition and ‘mirroring’ between task boundaries, knowledge boundaries, and firm boundaries has been suggested as a way to enhance managerial efficiency and as a source of potential strategic advantage. Despite its intuitive appeal, empirical support for ‘mirroring’ is significant but mixed. In this paper, we utilise an industrial economics and knowledge-based perspective to hypothesise how the combined effects of product architecture type, product complexity and the rate of product component change may influence task, knowledge and firm boundaries and hence be associated with either phases of mirroring or non-mirroring (‘misting’). We suggest that whether mirroring or misting is an efficient strategic choice is influenced by the characteristics of both the product architecture and the rate of technological change at the product component level, and changes across time as products evolve. Our framework helps to reconcile existing mixed evidence and provides the foundation for further empirical research.     

How work design characteristics affect service employees’ work–family conflicts

Despite scholars acknowledging that the five core job characteristics (i.e. skill variety, task significance, task identity, autonomy, and feedback) significantly positively influence employees’ psychological states (i.e. job meaningfulness, job responsibility, and results knowledge), few researchers have empirically studied how these job characteristics and psychological states are related to job involvement and work–family conflict (WFC). Research data were collected by conducting a survey of service employees through a market survey website. A total of 714 valid questionnaires were eventually collected, and structural equation modeling analysis was applied to the data. The results confirmed that skill variety and job involvement have a positive direct influence on WFC, whereas task feedback significantly decreases WFC. Additional analysis suggested that the five core job characteristics indirectly influence WFC through perceived job meaningfulness, responsibility, knowledge of results, and job involvement. The managerial implications for service managers developing employee work design strategies are provided.     

投资组合VaR分解的应用研究

针对VaR的不足,Garman M．于1997年提出了成分VaR和边际VaR。采用德尔塔——正态法度量投资组合的VaR、边际VaR和成分VaR,使用假设检验法对模型进行回测的研究结果表明,该计算方法下的VaR模型有效,边际VaR和成分VaR能为资产管理者提供更多有关投资组合风险的信息。     

中美税务会计理论比较及其差异解释：一个理论假说

中美税务会计理论总体上表现为结构的不平衡。采用归纳与实证方法,针对中美税务会计理论事实上的差异提出一个解释视角的假说,从引致的制度基础、理论需求与剩余、会计研究选题约束等方面进行推断,结论是美国税务会计理论是各种原因综合作用下一个实用主义观念的结果,中国税务会计理论体系不是杜撰的虚无,而是一个诱致性的理论变迁。
