Abstract

Three commercially available chemical substructure databases are reviewed: Chemical Abstracts, Index Chemicus, and the SANSS file (Chemical Information System). Coverage and overlap of Chemical Abstracts and Index Chemicus are studied, as well as differences between Chemical Abstracts as mounted by two different vendors (STN International and Questel). Guidelines for determining the database/system of choice are given.

Abstract

This chapter addresses the shortcomings of current self-efficacy models describing the health information practices of lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA+) communities. Informed by semi-structured interviews with 30 LGBTQIA+ community leaders from South Carolina, findings demonstrate how their self-efficacy operates beyond HIV/AIDS research while complicating traditional models that isolate an individual’s health information practices from their abundant communal experiences. Findings also suggest that participants engage with health information and resources in ways deemed unhealthy or harmful by healthcare providers. However, such practices are nuanced, and participants carefully navigate them, balancing concerns for community safety and well-being over traditional engagements with healthcare infrastructures. These findings have implications for public and health librarianship when providing LGBTQIA+ communities with health information. Practitioners must comprehend how the collective meanings, values, and lived experiences of LGBTQIA+ communities inform how they create, seek, share, and use health information to engage in successful informational interventions for community health promotion. Otherwise, practitioners risk embracing approaches that apply decontextualized, deficit-based understandings of these health information practices, and lack community relevance.

Abstract

This paper tests the pollution haven hypothesis by examining the relationship between environmental regulation and foreign investment with consideration of the role of corporate social responsibility, which has so far been neglected. Using multinationals’ investment data from China, our results in general support the pollution haven hypothesis that less stringent environmental regulation is more attractive for multinationals to invest in China, but high social responsibility can counteract attractiveness of weak environmental regulation.

Abstract

Purpose

This paper aims to assess the asymmetric effects of oil price shocks and the impact of oil price volatility on the Eurozone’s supersector returns, with a particular emphasis on the impact of the subprime crisis and the euro debt crisis (EDC) on this relationship.

Design/methodology/approach

Empirical data consist of daily observations of the 19 EURO STOXX supersector indices and the Brent crude oil price index for the period January 2001 to August 2015. This paper uses a non-linear multifactor market model. This model accounts for heteroscedasticity and breakpoints that are identified by the Bai and Perron (1998, 2003) tests.

Findings

The results show that supersector returns are sensitive to oil price shocks. However, in most cases, their responsiveness to oil price volatility is not significant. The relationship between oil price shocks and supersector returns changes through time and depends on the sector. Financial turbulence affects the oil-stock market nexus. In most cases, the subprime crisis has had a positive impact on the oil-stock market relationship, whereas the EDC has had an overall negative effect. Before the subprime crisis, there is an evidence of asymmetric effects for some supersectors. Meanwhile, for most sectors, the asymmetric effects disappear after 2008.

Originality/value

The study improves understanding of the interaction between oil price risk and the Eurozone sector indices returns. Furthermore, it enables global investors to manage the risk inherent to the portfolio managers’ positions.

Abstract

The complexity of the work of school leaders has intensified in recent years. The basic assumption underlying this article is that school leaders should develop a coherent vision of the school to effectively cope with the increased complexity of their work. In order to develop such a coherent vision, integration at a cognitive level is needed. In order to gain insight into both the complexity and integrity of the visions of school leaders, their tacit knowledge is studied using cause maps. More specifically, a method to elicit and interpret cause maps is explored and the analysis of the tacit knowledge, as expressed in the structure and content of their cause maps, indeed shows them to differ with regard to the level of cognitive integrity and balance within their cognitive repertoires.

Abstract

Standard macro theories have the same analytical structure as their micro counterparts. Where micro theories work with equilibrium between supply and demand for particular products, macro theories work with equilibrium applied to aggregates of products. This common approach treats the micro–macro relationship as scalable, with macro variables being aggregations over micro variables. In contrast, we pursue a systems-theoretic approach to the micro–macro relationship. This relationship is not scalable and rather entails a disjunction between micro- and macro-levels of theory. While micro phenomena are still susceptible to choice-theoretic analysis, macro phenomena are products of ecological interaction and so entail emergent phenomena. Our alternative approach treats macro theory as a form of systems theory where the behavior of the system has properties that are not reducible to properties of the individual elements within that system. Besides sketching this alternative approach, we examine some of the different insights this approach offers into such topics as unemployment and stabilization.

Abstract

Purpose

The purpose of this paper is to compare the effects on performance of two types of misfits (overfit vs underfit) as well as two types of fits (high-high fit vs low-low fit) between environmental uncertainty and supply chain flexibility.

Design/methodology/approach

The two asymmetry hypotheses have been tested with survey data from 212 Chinese manufacturing firms.

Findings

The results in general provided empirical evidences for the asymmetric effects in the fits and misfits between environmental uncertainty and supply chain flexibility. For the same degree of misfit, underfit deteriorates performance more than overfit. In addition, high supply chain flexibility fitting high environmental uncertainty (i.e. high-high fit) results in a higher performance than low supply chain flexibility fitting low environmental uncertainty (i.e. low-low fit).

Practical implications

It suggests that managers should strive to avoid the underfit of supply chain flexibility rather than the overfit, if the perfect fit is impossible to achieve. In addition, as it is beneficial to realize the fit of supply chain flexibility to high levels of environmental uncertainty, managers should probably embrace the highly uncertain environment and enhance the supply chain flexibility of their organizations to meet the increasing uncertainty of environment.

Originality/value

Fit and misfit are the core concepts to understand the relationships among environmental uncertainty, supply chain flexibility strategy, and performance. While the existing literature highlights the differential performance consequences of fit vs misfit between environmental uncertainty and supply chain flexibility strategy, the effects on performance are assumed to be the same for the two types of misfits, and two types of fits. The authors challenge these symmetry assumptions by arguing that overfit has a less negative effect on performance than underfit, and high-high fit has a stronger positive effect than low-low fit. The authors found empirical evidence in a large sample of Chinese manufacturing firms.

Abstract

Purpose

The purpose of this paper is to offer a comprehensive overview of challenges and risks of the Internet of Things (IoT) in supply chain management (SCM) and provide a structured framework for classifying and analyzing the relevant literature to deduce insights for research and practice.

Design/methodology/approach

A systematic literature review (SLR) of 102 peer-reviewed journal articles on the topic of IoT in SCM was conducted.

Findings

This review identifies, categorizes and describes the relevant literature regarding the dimensions time and specificity. The resulting framework contains a holistic overview including focus areas and relations of macro-environmental, network-related and organizational challenges and risks. Furthermore, this review represents a conceptual framework for future research, considering the multidisciplinary body of the subject and provides an analysis of the timeline of literature, journals and used methodologies.

Practical implications

This study offers valuable insights into IoT and its impact on applications, processes and the structure of organizations and supply chains (SCs). The identification of challenges and risks helps to prepare for changes in the future because of the disruptive nature of this technology.

Originality/value

The originality of this paper lies in the synthesis of the fragmented body of literature of IoT challenges and risks for SCM. The derived framework and identification of relations and research gaps provide the foundation for further research to evaluate the relations between challenges and risks and offer solutions.
