A microcosm experiment was carried out to provide a deeper insight into the toxic mechanisms exerted by two lipid regulator agents, as well as their interactions with the polyvinyl chloride microplastic on marine meiofauna. Two concentrations of Atorvastatin “A” and of Simvastatin “S”, (i.e., 0.6 mg.kg−1 and 6 mg.kg−1), as well as a single dosage of polyvinyl chloride microplastics “P” at 20 mg.kg−1, separately and their combined mixtures (“AP” and “SP”) were used on coastline dwelling marine meiofauna, with a main focus on nematodes. The results showed a significant reduction in meiofauna abundance in treatments compared to control. SIMPER analysis highlighted a significant decrease in the abundance of epigrowth feeders (2A), which possess conical (co) tails, and indistinct (id) amphideal foveas compared to control microcosms, reflected mainly in the decrease in abundance of the species Prochromadorella longicaudata. Furthermore, the contamination with microplastic affected only the omnivores-carnivores guild. Another finding of the current experiment is that the mixtures of microplastic with drugs lead to synergic interactions that increased their toxic effects on marine nematode communities.

My research explores the question: how can theorists better understand the ways in which planning technologies are used by municipal planners? In the case-study municipality, a recently introduced web-GIS technology had little demonstrable success in attaining two of its stated goals: enabling increased public access to municipal geographic information and encouraging planners to produce their own maps. My research links these outcomes not only to the technologies themselves, but to organizational structure and human agency. Planners and planning theorists can gain additional insight into the impact of planning technologies through closer attention to the process through which planners come to use information technologies and the way this process both alters and is constrained by existing organizational constraints, including previously adopted technologies.

How does the communication of information affect the pipeline industry? People are becoming more aware of the pipeline industry and how it may affect individuals and landowners in the future. Corporations are producing commuications tools to alleviate the lack of knowledge and the hidden value of energy pipelines. This case study examines two projects: “Passing through Edson” examines a winter pipeline construction job in Edson, Alberta. The story is told by the people on the job. We examine the environmental issues, economic impact, Native employment, and winter construction techniques. The “Boy Chief” video examines the impact of an archaeological dig on the prairies. In this program we have insight into the aboriginal history of the area and how the pipeline company is helping people learn more about the Native way of life. The paper examine how communication tools like these, allow employees access to information when communicating to stakeholders.

Recent cases provide insight into the role that an unethical corporate culture plays in financial statement fraud. The case of financial statement fraud in Olympus Corporation, a Japanese firm, provides the opportunity to examine how national culture plays a role in corporate governance and fraud detection. This case study focuses on the impact of Japanese culture on the corporate culture of The Olympus Corporation, and how that corporate culture resulted in financial statement fraud.

This study aimed to understand the impact and effects acquisition events have on an organisation’s brand equity. The literature highlighted a lack of pertinent research into the effects company acquisitions have on consumer-based brand equity (CBBE), especially what impact and consequences there may be on a brand that is acquired by another. This report investigated the overall acquisition process and proceeding effects the process had on an organisation’s CBBE. In order to achieve an in depth understanding, a case study approach was used. Here Rapha Racing Limited (RRL), a UK based up market manufacturer of cycling clothing and accessories for road riders, was explored. RRL was cited as it had recently experienced a £200 million acquisition by two heirs of the Walmart family. Primary research within the case took the form of surveying RRL consumers, interviewing RRL employees and a senior professional, who has been involved in numerous, high value company acquisitions. This multiple perspective approach allowed an insight into how RRL managed their brand throughout the acquisition and whether RRL managed to match, misjudge or exceed consumer brand expectations. This report found how RRL steadied the ship through a clear internal communication strategy with complete transparency between leadership and staff. However, it was found that RRL failed to apply the principle of transparency in their communications with consumers. The paper concludes that careful consideration of the acquiring party, protection of current business culture and systems as well as transparency with existing customers are vital components in controlling an organisation’s brand equity with an acquisition event.

PurposeThe purpose of this paper is to explain some divergent findings on experiences of fun at work. It explains conflicting findings by moving from a focus on classifying the activity (as, e.g. task/managed/organic) to foregrounding the dynamics of the experience, adding to the growing conceptualisation of fun at work as a multi-dimensional construct.Design/methodology/approachThis research draws on empirical data obtained through case study and interviews with 13 participants from two organisations. These interviews were subjected to intense thematic analysis.FindingsIt was found that an individual’s underlying beliefs about the organisation; the perceived drivers of the fun practice; and the level of control exerted over a fun practice significantly shape the experience. The paper draws on the concept of the psychological contract to frame the relationship between these three key interacting elements.Practical implicationsThis paper provides a greater understanding of the dynamics of fun experiences, enabling management to better recognise and contextualise the impact of fun practices.Originality/valueGiven conflicting findings on both the experience and outcomes of fun at work, this study elucidates the dynamics underpinning the experience of fun at work. It is novel to consider experiences of fun through the lens of psychological contracts, which offers fresh insight into the understanding of individual experiences of fun.

Abstract The present article explores the profound impact of intercultural contact on identity, a topic that is gaining in relevance as multicultural experiences become increasingly common in globalised societies. The focus of the investigation is on the impact of culture and language upon the process of migrant identity (re) building in interaction with the new environment. Theory is applied to the analysis of Eva Hoffman’s memoir Lost in Translation-A Life in a New Language (1998), which offers a profound insight into these complex dynamics. In the first section, intercultural contact is investigated as a bidirectional translation process with both a disruptive and a reinforcing influence on individual identity, as shown through the concepts of hybridity and triangulation. The first section also highlights the points of contact between self-translation and interlingual translation to enhance understanding of their shared challenges. The second section focuses on the interconnection between language and migrant identity and argues that L2 proficiency may be regarded as the fundamental competence to accomplish successful self-translation. The depth of this impact is shown at multiple levels of identity: personal, enacted and social.

The impact of juvenile delinquency on society is an issue of great concern. The impact of delinquent behaviors goes beyond the victim to include the offender, the offender’s family and society as a whole. A review of the existing literature reveals multiple studies, which examine delinquency from a causal perspective. Despite the efforts of researchers a definitive causal link is not readily determined. Ethical concerns centering around a quantitative study on delinquency precludes the discovery of such a causal link. Utilizing a qualitative study approach we may not be able to identify causal relationships; however, this approach provides clear insight into the lived experiences of the individuals being studied and in turn offers us the possibility of understanding what these experiences were and how they possibly impacted the individual. It is through this understanding of the lived experiences that we gain insight. This insight will, hopefully, facilitate the prediction of and the mediation of anti-social juvenile behavior.

Abstract Using Elena Ferrante’s Neapolitan novels as case study, this article presents a cognitive approach to fictionality and authorial intention using Text World Theory and Mind-Modelling. It investigates two forms of ontological distortion: readers’ (mis)classification of the novels’ genre (as autofiction or autobiography) and the problem posed by the author’s pseudonymic identity. The analysis has three parts: first, I conduct a Text World analysis of the novels’ syntactic/stylistic similarities to autobiography and, in doing so, reveal its ontological structure; second, I consider the ontological liminality of narration and the ways in which readers build an authorial mind-model of Ferrante; thirdly, I explore the assessment of critics and/as readers of the text’s fictionality and the impact of Ferrante’s pseudonym on perceptions of authorial intentionality and the authorial mind-model. Ultimately, I argue that a cognitive approach offers greatest insight into readers’ interpretations of authors and of fictionality.

This paper examines the impact of privatisation on workers’ compensation in privatised state-owned enterprises in Bangladesh. The study employs five case studies using a qualitative approach. Studying multiple cases is considered more reliable as it permits replication and extension. The qualitative approach helps to build a holistic picture, which allows for the assembling of a comprehensive and complete report of the issues under investigation. The research finds that workers’ compensations in most privatised case study organisations are less than their counterparts in comparable state-owned and privately-owned organisations. The findings have important implications for the privatisation programmes in Bangladesh as the study focuses on workers who are the major workforce of privatised organisations and generates qualitative data that provides greater insight into the impact of privatisation on workers’ compensation in Bangladesh.

AbstractThis article discusses the concept of ‘religious regimes’ in order to identify institutionalised arrangements regulating the social position of religion. By analysing such regimes and the views underpinning them, three visions of the societal role of religion come into focus: segmented pluralism, the Christian nation and the secular nation. Taking up Dutch post-war history as a case study, it becomes clear that religious regimes regularly result from fragile compromises. The concept thus yields insight into the gradual transitions between different institutional arrangements regarding religion and into the impact of changing views on the societal role of religion within and outside religious communities.
