A Cramér-type large deviation theorem for sums of functions of higher order non-overlapping spacings

Let U ₁, U ₂, . . . , U _n–1 be an ordered sample from a Uniform [0,1] distribution. The non-overlapping uniform spacings of order s are defined as \({G_{i}^{(s)} =U_{is} -U_{(i-1)s}, i=1,2,\ldots,N^\prime, G_{N^\prime+1}^{(s)} =1-U_{N^\prime s}}\) with notation U ₀ = 0, U _n = 1, where \({N^\prime=\left\lfloor n/s\right\rfloor}\) is the integer part of n/s. Let \({ N=\left\lceil n/s\right\rceil}\) be the smallest integer greater than or equal to n/s, f _m (u), m = 1, 2, . . . , N, be a sequence of real-valued Borel-measurable functions. In this article a Cramér type large deviation theorem for the statistic \({f_{1,n} (nG_{1}^{(s)})+\cdots+f_{N,n} (nG_{N}^{(s)} )}\) is proved.     

Consequences of extended work hours: A comparison of moonlighters,overtimers, and modal employees

Stringent corporate controls on employee moonlighting and/or overtime are not uncommon. But are they necessary? Even the concept of overtime may need to be rethought—what about the “normal working hours” of managers and professionals who work hours at home or on the road—hours typically uncompensated?     

Product standardisation in the food service industry: post-purchase attitudes and repurchase intentions of non-Muslims after consuming halal food

In order to satisfy the Muslim market segment, many restaurant and fast food companies in Western countries have standardised their products by switching to halal. The purpose of this research is to discover the extent to which non-Muslim consumers in non-Muslim countries experience cognitive dissonance when they think about restaurants and fast food outlets having likely served them halal-produced food, and the extent to which these consumers intend to repurchase halal food. Data came from a total sample of 1097 non-Muslim consumers in Canada, Spain and the United Kingdom. The full model, with religious identity, ethnic identification and interest in animal welfare as antecedents of cognitive dissonance, explained 35% of the variance in consumers’ repurchase intentions. Our findings suggest that many non-Muslims do not have a particular issue with consuming halal food, but they may react negatively if they unintentionally consume halal food and perceive that they have been deprived of information, or worse still, deliberately deceived. The research makes a number of contributions to marketing knowledge with regard to the negative spillover effects that can result from faith-based product standardisation, and the influences of consumer interest in animal welfare and deprivation of product information on consumer behaviour.     

Waqf,perpetual charity,in a general system theory of tawhidi metascience

This article is premised on the intercausal socioeconomic embedded model of ethical design of perpetual charity in Islam called waqf. Such a model is formalized according to the theory of unity of knowledge in the light of the Primal Ontology of Divine Oneness called Tawhid in the Qur'an. Tawhid is argued to be the only foundational Law of Islam respecting “everything.” The implications of such an epistemic treatment in respect of waqf as an example of the whole class of charities in Islam is shown to be unlike the dissociative and human opinionated nature of what has now come to be known as “shari'ah‐compliance.” The Islamic shortfall of “shari'ah‐compliance” and its segmentation as opposed to organically unified synergy between the socioeconomic and moral/ethical variables of the objective criterion called the Well‐being Function have deprived the entire study of the present days' Islamic economics, finance, and banking from its true epistemological core of Tawhid as Law. To restore this true foundation in Islamic thought, a theory of metascience of Tawhid is presented. Waqf in Malaysia is studied as an example from the perspective of Tawhidi unity of knowledge, contrary to its existing dissociative presence in the ethically exogenous socioeconomic treatment under “shari'ah‐compliance.”     

Examining the extent of and determinants for sustainability assurance quality: The role of audit committees

This study examines the extent of and determinants for sustainability assurance quality. Data comprise sustainability assurance statements published by the top 100 listed companies in Australia and New Zealand from 2017 to 2019. The findings indicate that Australian companies lead their New Zealand counterparts in sustainability assurance. Although sustainability reporting has risen, assurance rates remain significantly low. Accountants dominate the market, and companies prefer to use their own auditors for sustainability assurance work. Sustainability assurance quality is poor and does not vary significantly among Australian and New Zealand companies. Low-quality sustainability assurance plays a limited role in mitigating potential stakeholder–agency conflicts. The regression analysis indicates that audit committee characteristics such as members' independence, industry/market expertise, and attending meetings enhance sustainability assurance quality, whereas audit committee size has no affect. These findings suggest that audit committee characteristics such as independence, industry expertise, and regular meeting attendance have the potential to reduce stakeholder–agency conflicts by improving the quality of sustainability statement assurance. Our findings build on the sustainability assurance literature by exploring current trends in sustainability assurance practices in Australia and New Zealand where corporate governance codes have been recently revised. Further, these findings are timely given recent changes in standards (International Standard on Assurance Engagements [ISAE] 3000 and Global Reporting Initiative [GRI]). Our study contributes to the audit committee literature and sheds light on the role played by audit committee characteristics on sustainability assurance statement quality. The study findings potentially offer useful insights for practitioners, standard setters, and regulators.     

In Vino ‘No’ Veritas: impacts of fraud on wine imports in China

China is one of the largest wine importing countries in the world and is poised for continued import growth in the future. Increased wine purchases throughout China have given rise to persistent fraud where fake wines are packaged and sold with counterfeit contents and labels. For exporting countries like France, counterfeit wines displace market share, damage foreign brand reputation, and cause distrust in consumers who are aware of counterfeiting problems throughout the country. We examine the impact of fraudulent wine events (as measured by negative media reports) on Chinese wine demand differentiated by supplying country. We employ the Rotterdam demand system and a switching regression procedure to estimate import demand and compare results across different media variable specifications. Results consistently show that negative reports disproportionately affect French wine regardless of how the media variable is specified. This is not surprising because most fraudulent events involve French wine counterfeits.

The exceptional performance of exporters and labour market outcomes: evidence from Egyptian firms

ABSTRACT

This paper examines the manufacturing export market in Egypt after the Arab Spring using a novel firm-level census dataset from 2013. Export is very rare in Egypt. The conventional export premia are very high, except for total factor productivity. Exporters have stark effects on labour market outcomes, including wages, employment, demand for skilled and female workers, wage inequality, and job security. These findings have two important implications: (1) Manufacturing exports might be monopolized by large firms, and (2) promoting exports could improve labour market outcomes, especially for skilled and female workers.     

Online Repurchasing: The Role of Information Disclosure,Hope, and Goal Attainment

The emergence of online purchasing has changed the relationship between consumers and brands. Our research focuses on online information disclosure and consumer hope in an online shopping environment. Two studies are undertaken to test the theoretically derived hypotheses. Study 1 evaluates the causal relationship between information disclosure and hope via an experiment in an online shopping context. Study 2 involves an online survey to test the nomological network presented in this research. The models identify the moderating effect of consumer product knowledge on online information disclosure and consumer hope. For academics, this research advances knowledge of how consumers' confidence in sharing personal information develops hope, consequently enabling them to attain their goals and repeat their purchases. For practitioners, it offers a better understanding of how investments are successful in aiding consumers to attain their goals and generate repeat purchase intentions in an online shopping environment.     

How career plateau beliefs and leader interpersonal unfairness harm job performance in dysfunctional organizational settings

Building on social exchange theory and attribution theory, this study unpacks the relationship between employees' perceptions of organizational politics and job performance, considering the mediating effect of career plateau beliefs and the moderating effect of leader interpersonal unfairness. The findings provide empirical support for the theoretical predictions. An important reason for which perceptions of dysfunctional organizational politics reduce job performance is that employees develop beliefs that opportunities for their career development are limited. This mediating role of career plateau beliefs is particularly salient to the extent that employees are exposed to organizational leaders who treat them with disrespect. Organizations can mitigate the risk that highly politicized decision-making processes lead to negative performance outcomes by stimulating fair interpersonal relationships.
