This article aims to explore the impact of the Great War on the Sheffield armaments industry through the use of four company case studies in Thomas Firth, John Brown, Cammell Laird and Hadfields. It charts the evolving situation the armaments companies found themselves in after the end of the conflict and the uncertain external environment they had to engage with. The article also examines the stagnant nature of armaments companies’ boards of directors in the 1920s and the ultimate rationalisation of the industry at the close of the decade.

The research design is based around a close examination of the surviving manuscript records of each of the companies included, the records of the speeches recorded by chairpersons at annual meetings and some governmental records.

The article concludes by outlining how the end of the Great War continued to affect the industry for the following decade and the complex evolving situation with a changing external environment and continuity of management internally ultimately leading to mergers in the industry.

This article uses a number of underused manuscript records to examine the Sheffield armaments industry and explores the effect of a global mega event in the Great War on one of the most technologically advanced industries of the period.

The purpose of this paper is to propose a new measure for organization health. It is proposed that the Donohue tripartite paradigm model can be used to pierce the veneer of the satisficing account to identify the moral appraisal stakeholders have made of corporate strategies based on external (i.e. economic, etc.) standards.

A cognitive mapping process through narratives is used to operationalize a tripartite paradigm framework to measure human capital. An existential‐phenomenological approach is adopted to ensure the figural integrity of data.

This paper can be viewed as the prototypical development phase for a methodology to support future real‐time ethical inquiry concerning social responsibility within the corporate world.

The tripartite paradigm model expressed by Donohue was intended for “real‐time” application. This study, however, proposed a retrospective analysis of stakeholder decision‐making within a firm as a means of unearthing any deficiencies that might block the operationalization of Donohue's generalist theory.

This appraisal can identify the conflict of conscience that characterizes a stakeholder's “lived‐worlds” based on their participation and exposure to company decision making. This diagnostic tool can assist stakeholders in identifying evidence of decline early enough in the history of an organization for proactive remedial action to be taken.

It is the hope of this study that the proposed cognitive mapping process can derive a measure of organizational health through an existential‐phenomenological approach to ensure the integrity of the data. Ultimately, the aim is that this will be a tool that can explore the phenomenon of misrepresentation and its effect on social cooperation within a market culture.

In the domain of information science, affordance is a relatively new concept that deserves further exploration. It may serve as a bridge to narrow the research-practice gap that has persisted in information studies. Building upon previous research, we call for a broader concept of affordance that would help researchers understand information practices from an ecological perspective.

The study focuses on conceptualizing affordances for information practices in order to theorize engagement among people, technology, and sociocultural environments. We develop a hierarchical model and a component model to illustrate how key tenets of affordances can be linked with the decomposition of activities and its mechanism. Following this, we describe an illustrative case of a popular Chinese cloud-based music platform to demonstrate the utility of our conceptual frameworks in guiding studies of information practices.

The study proposes to shift the focus of technology affordances, which highlights the features and functions of particular technologies, to the affordances for practices that are enacted through technology and social construction within a sociocultural environment. The illustrative case of the cloud-based music platform shows that the proposed models can provide a structured view of operations, actions and motives for music information practices. The processes of internalization and externalization offer insight into the decomposition of information practice as a chain of activity-action-operation.

This study contributes to the literature on theorizing engagement among people, technology and sociocultural environments through the theoretical lens of affordances and sheds new light on the challenges of information practice.

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Corporate culture is a spirit formed by the shared values of the individuals in the organization that has potential to make the library more than the sum of its parts, both positively and negatively. It is the vehicle by which the organization defines itself, for both itself and the clientele, with the purpose of providing the best service possible by sharing a vision of the organization as an organic whole. It operates through the power of peer influence rather than direct vertical authority. This paper takes a holistic approach to a concept that is more complex than it first appears; it addresses the molding of corporate culture, not as a management function, but as a complex and deep system, being in effect the soul of the organization, which resides in the motivation of each individual and which, therefore, requires a special kind of leadership.

While anonymous online interactions could be helpful and less risky, they are usually not enough for LGBTQ+ people to satisfy the need of expressing their marginalized identity to networks of known ties (i.e. on identified social media like Facebook, WeChat, and TikTok). However, identified social media bring LGBTQ+ people both sources and challenges like “context collapse” that flattens diverse networks or audiences that are originally separated. Previous studies focus on LGBTQ+ people's disclosure and responses to context collapse, few studies investigate how their perceptions of context collapse are shaped and their privacy management beyond regulating disclosure on social media. Drawing on identity theory and communication privacy management (CPM), this study aims to investigate how the need of LGBTQ+ people for self-identity affects their perceived context collapse and results in privacy management on identified social media.

Given the target population is LGBTQ+ people, The authors recruited participants through active LGBTQ+ online communities, influential LGBTQ+ activists, and the snowballing sampling. The authors empirically examined the proposed model using the PLS-SEM technique with a valid sample of 232 respondents concerning their identity practices and privacy management on WeChat, a typical and popular identified social media in China.

The results suggested that the need for expressing the self and the need for maintaining continuity of self-identity have significant influences on perceived context collapse, but vary in directions. The perceived context collapse will motivate LGBTQ+ individuals to engage in privacy management to readjust rules on ownership, access, and extension. However, only ownership management helps them regain the perceived privacy control on social media.

This study incorporated and highlighted the influence of LGBTQ+ identity in shaping context collapse and online privacy management. This study contributes to the literature on privacy and information communication and yields practical implications, especially on improving privacy-related interactive design for identified social media services.

Purpose – Utilizing the intersectionality framework, this study examines how a racially diverse group of adults aim to balance work–family life.Methodology/approach – This chapter uses qualitative data from the Intersections of Family, Work, and Health Study consisting of 132 black, white, and Mexican-American adults.Findings – We find that socioeconomic status and marriage provide social and economic capital to more easily fulfill role obligations. Individuals with more capital have more choices and are offered a chess board and a variety of pieces to facilitate the goal of creating work–family harmony. Individuals with less capital end up with less job flexibility and play checkers through rigid concrete roles because work decisions are in the hands of their employers instead of their own.Social implications – This chapter sheds light on the influence of high social status and the ability some individuals have to maximize both job flexibility and autonomy in managing work–family life. As we show here, married middle-class whites are able to manage work–family life better than professional black single mothers and working class Mexican Americans by having the ability to choose to play checkers or chess.Originality/value of chapter – We argue that the concept of “balancing” does little to express the ways individuals negotiate the constraints of work and family. By using an intersectionality perspective, we show that conceptualizing work–family life as “checkers or chess” games allow for the cognitive process of decision making (in terms of, for example, time pressures and perceived role demands) to be assessed more efficiently across work–family domains.

The purpose of this paper is to explore the hidden social worlds of competent clandestine users of drugs controlled within the confines of the UK Misuse of Drugs Act 1971, which now includes NPS substances. The authors explore how and in what way socially competent drug users differ from others who are visible to the authorities as criminals by criminal justice bureaucracies and known to treatment agencies as defined problem drug users.

This qualitative research utilises a bricoleur ethnographic methodology considered as a critical, multi-perspectival, multi-theoretical and multi-methodological approach to inquiry.

This paper challenges addiction discourses and, drawing upon empirical evidence, argues the user of controlled drugs should not be homogenised. Using several key strategies of identity management, drug takers employ a range of risk awareness and risk neutralisation techniques to protect self-esteem, avoid social affronts and in maintaining untainted identities. The authors present illicit drug use as one activity amongst other social activities that (some) people, conventionally, pursue. The findings from this study suggest that punitive drug policy, which links drug use with addiction, crime and antisocial behaviour, is inconsistent with the experience of the participants.

Due to the small sample size (n=24) employed, the possibility that findings can be generalised is rendered difficult. However, generalisation was never an objective of the research; the experiences of this hidden population are deeply subjective and generalising findings and applying them to other populations would be an unproductive endeavour. While the research attempted to recruit an equal number of males and females to this research, gendered analysis was not a primary objective of this research. However, it is acknowledged that future research would greatly benefit from such a gendered focus.

The insights from the study may be useful in helping to inform future policy discourse on issues of drug use. In particular, the insights suggest that a more nuanced perspective should be adopted. This perspective should recognise the non-deviant identities of many drug users in the contemporary era, and challenge the use of a universally stigmatising discourse and dominance of prohibition narratives.

It is envisaged that this paper will contribute to knowledge on how socially competent users of controlled drugs identify and manage the risks of moral, medical and legal censure.

The evidence in this paper indicates that drug use is an activity often associated with non-deviant, productive members of the population. However, the continuing dominance of stigmatising policy discourses often leads to drug users engaging in identity concealment within the context of a deeply capitalist Western landscape.
