Adoption of farm‐based irrigation water‐saving techniques in the Guanzhong Plain,China

This article analyses adoption of farm‐based irrigation water saving techniques, based on a cross‐sectional data set of 357 farmers in the Guanzhong Plain, China. Approximately 83% of the farmers use at least one farm‐based water‐saving technique. However, the traditional, inefficient techniques border and furrow irrigation are still prevalent whereas the use of advanced, more efficient techniques is still rather rare. We develop and estimate an adoption model consisting of two stages: awareness of water scarcity and intensity of adoption. We find that awareness of water scarcity and financial status enhance adoption of more advanced techniques whereas access to better community‐based irrigation infrastructure discourages it. We furthermore find both community‐based irrigation infrastructure and farm‐based irrigation water‐saving techniques have mitigating effects on production risk. From the results it follows that adoption can be stimulated via financial support and via extension aimed at enhancing awareness of water scarcity.     

The major determinants of logistic performance in a global perspective: evidence from panel data analysis

The global logistics industry has grown significantly and logistics has become an important sector of the business economic system and a major global economic activity in recent years. Logistics activities accelerate economic and productivity growth. Efficient logistics is also important to a country’s competitiveness and source of employment. The purpose of this paper is to uncover and understand the major determinants of logistics performance (LP) to further lift the LP of countries. Using unbalanced panel data of 93 selected countries from 2007 to 2014, the present research attempts to critically investigate the major determinants of LP. In estimating the model, this study prefers to use static panel data approach owing to limited data. The findings of the present study reveal that (a) countries with low level of corruption and stable political environment are likely to yield a high level of LP; (b) improvement in resources supply such as infrastructure, technology, labour, and education also have a significant positive effect on LP. Therefore, institutional reforms and upgrading resources will effectively accelerate LP.     

The differential effects of CEO narcissism and hubris on corporate social responsibility

Research Summary: While prior studies have predominantly shown that CEO narcissism and hubris exhibit similar effects on various strategic decisions and outcomes, this study aims to explore the mechanisms underlying how narcissistic versus hubristic CEOs affect their firms differently. Specifically, we investigate how peer influence moderates the CEO narcissism/hubris—corporate social responsibility (CSR). With a sample of S&P 1500 firms for 2003–2010, we find that the positive relationship between CEO narcissism and CSR is strengthened (weakened) when board‐interlocked peer firms invest less (more) intensively in CSR than a CEO's own firm; the negative relationship between CEO hubris and CSR is strengthened when peer firms are engaged in less CSR than a CEO's own firm. Managerial Summary: Some CEOs are more narcissistic while others may be more hubristic, but these two groups of CEOs hold different attitudes toward the extent to which their firms should engage in corporate social responsibility (CSR). Our findings with a large sample of U.S. publically listed firms suggest that narcissistic CEOs care more about CSR, but hubristic CEOs care less. Interestingly, when narcissistic CEOs observe their peer firms engaging in more or less CSR than their own firms, they tend to respond in an opposite manner; in contrast, hubristic CEOs will only engage in even less CSR when their peers also do not emphasize CSR. Our findings point to a fundamental difference between CEO narcissism and hubris in terms of how they affect firms' CSR decisions based on their social comparison with peer firms.     

The impacts of governance and institutions on inbound tourism demand: evidence from a dynamic panel data study

This study explores the impact of governance and institutions on inbound tourism demand in Malaysia using a dynamic panel data approach for 45 tourism source countries over the period 2005–2015. The results show that institutions play a very important role in explaining the behaviour of inbound tourism demand. To obtain a better picture, we investigate the response of international tourists to disaggregated institutional quality. We find that international tourists are more concerned about political stability, governmental effectiveness, regulations, laws, and corruption than voice and accountability. Therefore, policymakers should focus on ways to improve institutional quality to significantly increase international tourist arrivals.     

Seeing relationships through the lens of psychological contracts: the structure of consumer service relationships

Serving as mental models, psychological contracts guide consumers’ service interactions with their service providers. This study incorporates a psychological contract perspective into the relationship marketing literature, exploring service customers’ beliefs about the terms and conditions of the resource exchange process and the types of relationships they form with service providers. It provides new insights that explain why and how some customers respond favorably to a company’s relationship overtures and investments while others do not. A latent class analysis on a sample of 700 consumers across three different service industries reveals that consumers form four distinct types of psychological contracts: relational, standard, transitional, and captive. To further validate the differences between the contract types, open-ended responses from the respondents were sorted by each class. The distinctive themes that emerged provide a richer understanding of the characteristics of each class beyond those inferred from the quantitative results. Each contract type is also profiled against its underlying level of trust, satisfaction, and commitment to understand the relationship between the contract types and these traditional relationship marketing variables. Marketers can differentiate their relationship marketing strategies and allocate their resource investments more effectively by segmenting consumers according to their psychological contract type.     

Job stress and well-being of female employees in hospitality: The role of regulatory leisure coping styles

The job stress and coping behavior of female employees has become a key issue in the hospitality industry. This study investigates the moderating role of regulatory leisure coping styles on the effect of job stress on female employees’ well-being. Specifically, this study extends Patry et al.’s (2007) findings to further confirm the direct and moderating role of regulatory leisure coping styles in the relationship between job stress and well-being. Data were collected from the female employees of 22 tourist hotels in Taiwan. The results showed that the Planned-Breather Leisure Coping Style (PBLCS) was positively and significantly associated with well-being, whereas the Avoidant Leisure Coping Style (ALCS) had a negative and significant effect on it. In addition, the results also revealed that the PBLCS plays a buffering role, but that the ALCS plays an amplifying role. Based on these findings, the implications and research suggestions are then discussed.     

絮凝沉淀去除马铃薯淀粉加工废水中蛋白的试验研究

采用絮凝沉淀法去除马铃薯淀粉废水中的蛋白质。经过方案比选．最终选择聚丙烯酰胺作为絮凝剂,结果表明：在聚丙烯酰胺投加量为70mg／L,pH值为5,温度为20℃,反应时间40min的最佳工艺条件下。采用聚丙烯酰胺絮凝沉淀法对马铃薯淀粉加工废水中的COD、蛋白质、BOD、SS都有一定的去除效果。COD的去除率保持在30％～40％,蛋白质的去除率保持在45％～55％,BOD的去除率保持在10％-15％．SS的去除率保持在50％-60％,大大减轻了后续处理构筑物的负担。     

港口集装箱运输与腹地经济发展

港口集装箱运输与腹地经济发展是一种互动关系.港口集装箱运输的发展主要取决于腹地内集装箱的生成量和运输条件、运输费用等方面.同时,集装箱运输对腹地经济的发展也正在发挥着越来越重要的作用.本文主要选择上海、天津、广州、青岛、大连、宁波、深圳等亿吨港口为研究对象,从集装箱吞吐量、港口吞吐量以及腹地经济发展的角度,分析港口集装箱运输与腹地经济的互动及其变化趋势、现存问题,并提出互动发展的对策.
