Doing more and doing better are two different entities: Different patterns of family control and environmental performance

Family firms bear two types of agency costs, including type I and type II agency problems, in corporate environmental practices: (1) Outside executives at family firms hesitate to engage in environmental strategies, which can lead to drops in profits; (2) Controlling families employ opportunistically environmental management to achieve their interests. We argue that a primary cause for the agency problems lies on ineffective internal corporate governance at family firms, which can cause loss of managerial (or power) balance between outside executives and family executives. Our findings show that family firms with ownership and strategic control (FSC), which family executives and outside executives monitor and constrain each other, can achieve the highest environmental performance. Moreover, external controls, including product market competition and provincial environmental regulations, substitute effective internal control of FSC. The environmental performance premium of FSC is more prevalent when the production market competition is lower. Family firms with ownership, operational, and strategic control (FOSC) can achieve higher environmental performance within a province with more stringent environmental regulations.     

Evaluating museum visitor experiences based on user-generated travel photos

ABSTRACT

This research introduces online travel photos published on social media platforms as a complementary data resource to examine the behavior and experience of museum visitors. The practical value of online travel photos is demonstrated through a case study of popular Hong Kong museums, particularly by using the photo content and metadata available from the Flickr platform. The proposed approach is a generic method for understanding museum visitor behavior and preferences, and supports museum practitioners in developing improved products for visitors. The case study findings are particularly beneficial for tourism managers, especially those in Hong Kong, in promoting and attracting tourists to visit local museums.     

Does bank competition promote financial inclusion? A cross-country evidence

The idea of financial inclusion has recently been discussed as one of the key strategies to enhance economic development (World Bank 2014). We move this discussion forward by examining if bank competition is a crucial component enforcing financial inclusion, which is arguably a finance supply-side driven process. In this study, we compute the financial inclusion index built on Sarma (2008) approach to better reflect banks’ willingness and capability to provide financial services. Applying System Generalized Method of Moments to the panel of 93 countries, we find that bank competition promotes financial inclusion.     

论政府在经济发展中的生态责任

当前人类面临人口过度膨胀、环境污染严重和资源枯竭等一系列发展的难题，并已成为社会发展的障碍，这些结果的出现并不是短时间造成的，而是长时间积累的结果；既有主观上的原因、客观上的原因和管理上的原因。①主观原因。长时间以来，人们一直认为人类是自然的主宰，自然界是人类征服的对象，自然界的一切都是人类的，人们有一种必定胜天的信念。在这种理念的支配下，人们做出了各种各样违背自然发展规律的蠢事；比如填海造田、毁林造田、过度放牧、滥杀动物、排放有毒有害的废水废气以及过度开发各种矿藏等，人类的这些行为大大超过了自然界这个生态系统的恢复能力，     

Prescribed conditional interaction structure models with application to the analysis of mobility tables

The present paper considers some new models for the analysis of multidimensional contigency tables. Although the theoretical background used here appeared already in Haberman (1974), prescribed conditional interaction (PCIN) models were introduced by Rudas (1987) and their mathematical properties were worked out by Leimer and Rudas (1988). These models are defined by prescribing the values of certain conditional interactions in the contingency table. Conditional interaction is defined here as the logarithm of an appropriately defined conditional odds ratio. This conditional odds ratio is a conditional version of a generalization of the well known odds ratio of a 2×2 table and that of the three factor interaction term of a 2×2×2 table and applies to any number of dimensions and any number of categories of the variables. The well known log-linear (LL) models are special PCIN models. Estimated frequencies under PCIN models and tests of fit can be computed using existing statistical software (e.g. BMDP). The paper describes the class of PCIN models and compares it to the class of association models of Goodman (1981). As LL models are widely used in the analysis of social mobility tables, application of more general PCIN models is illustrated.     

哪种VoIP设备能迎合未来需求?

VoIP电话基础设施设备市场在快速增长并不断变化,在今后几年可能会有全新的设备投放市场。准确预测市场需要什么类型的设备是很难的,因为IP多媒体子系统(IMS)这个即将出台的体系结构标准将包含一些老设备类型,并导致全新设备类型的出现。位于美国加州Campbell的市场调查公司Infonetics Re- search的分析师Ste phane Te ral介绍说, IP多媒体子系统标准定义了3种功能:归属用户服务、会话呼叫控制功能和媒体资源功能。尽管所有大公司均计划实施IMS,但它们几乎没有交付什么设备。     

When new product development fails in China: mediating effects of voice behaviour and learning from failure

This paper investigates conflicts following a new product development (NPD) failure. Conducted in a Chinese business setting, the study examines whether voice behaviour and learning from failure mediate the relationship between task- and emotional conflict emerging from NPD failure. Our findings indicate that voice behaviour and learning from failure are necessary to effectively reduce task and emotional conflict and thus to enhance future NPD. Specifically, it is revealed that emotional conflict leads to a reduced level; and that voice behaviour and learning from failure are significant mediators that influences the relationships between emotional and task conflicts with it.     

Differences in Roma and non-Roma students’ ratings of their peers’ popularity: an inquiry into the oppositional culture in Hungarian schools with the use of a survey experiment

Quality & Quantity - Oppositional culture theory posits that students who belong to oppressed ethnic minority groups define their ethnic identity in opposition to the majority of students....     

Climate,diseases, and the origins of corruption

It has been commonly observed that tropical countries tend to suffer from intense corruption and underdevelopment. This study provides an explanation for this long-standing disparity across the world based on variation in the intensity of ultraviolet radiation (UV-R). The central hypothesis is that UV-R is positively associated with the (historical) prevalence of eye diseases, which significantly shortens work-life expectancy as a skilled worker. This helps shape the worldwide distribution of corruption by affecting the incumbents' window of opportunity. Using data for up to 139 countries, I consistently find empirical support for the positive relationship between UV-R and corruption. The main findings withstand accounting for numerous alternative explanations for international differences in corruption levels. Employing individual-level data from the World Values Survey, I document suggestive evidence that exposure to UV-R is linked to surveyed respondents' tolerance towards corrupt activities. Furthermore, a subnational analysis for China lends credence to the cross-country evidence.     

Social media bots and stock markets

This study examines the link between information spread by social media bots and stock trading. Based on a large sample of tweets mentioning 55 companies in the FTSE 100 composites, we find significant relations between bot tweets and stock returns, volatility, and trading volume at both daily and intraday levels. These results are also confirmed by an event study of stock response following abnormal increases in the volume of tweets. The findings are robust to various specifications, including controlling for traditional news channel, alternative measures of volatility, information flows in pretrading hours, and different measures of sentiment.
