Abstract

Purpose

A generalization of Ascoli–Arzelá theorem in Banach spaces is established. Schauder's fixed point theorem is used to prove the existence of a solution for a boundary value problem of higher order. The authors’ results are obtained under, rather, general assumptions.

Design/methodology/approach

First, a generalization of Ascoli–Arzelá theorem in Banach spaces in Cn is established. Second, this new generalization with Schauder's fixed point theorem to prove the existence of a solution for a boundary value problem of higher order is used. Finally, an illustrated example is given.

Findings

There is no funding.

Originality/value

In this work, a new generalization of Ascoli–Arzelá theorem in Banach spaces in Cn is established. To the best of the authors’ knowledge, Ascoli–Arzelá theorem is given only in Banach spaces of continuous functions. In the second part, this new generalization with Schauder's fixed point theorem is used to prove the existence of a solution for a boundary value problem of higher order, where the derivatives appear in the non-linear terms.

Abstract

The process of knowledge production is usually assigned to scientists who use specific methods to extract knowledge from someone else's experience. Usually this includes collecting, aggregating and interpreting data from an uninvolved point of view; that is, from the outside. This procedure is supposed to guarantee objectivity and generalisation. Many child sexual abuse (CSA) survivors reject such an approach that turns them into objects again. This presents a problem for research because it limits the number and contribution of potential participants and can lead to bias. In self-help groups of CSA survivors, an enormous amount of experiential knowledge accumulates, and sometimes this is transferred into more than only individually valid knowledge. Based on this experience and aiming for more agency of CSA Survivors, a group of adult survivors and researchers developed a new approach to research. It focuses on the development of self-organised research, which enables survivors of sexualised violence to practice research without losing agency. They are indispensable and elementary parts in all phases of the process. This chapter shows one way of formalising this process so quality criteria can be developed and applied. Following the presented approach, evaluation of the presented methods is the appropriate next step because self-help groups give reason to estimate significant outcomes. These outcomes not only enable self-help groups of CSA survivors to incorporate new methods but also include the chance to empower adults, children or youth who have been victims of sexualised violence.

Abstract

Purpose

Action design research (ADR) has become widely accepted as a prominent research method within information systems when managing design-oriented research projects. One purpose of the ADR method is to provide methodological guidance for the building of IT artefacts. However, several scholars have reported a lack of guidance of method support at the micro level. This article aims to complement the macro level of the ADR method by integrating prescriptive method support at the micro level.

Design/methodology/approach

A qualitative approach including direct content analysis. An empirical ADR project was analysed in order to identify method support that could be integrated into the ADR method.

Findings

Method support at the micro level was identified for all the stages of the ADR method. The method support consists of procedural support, guiding concepts, and various techniques for the documentation of project tasks stated in the ADR method.

Research limitations/implications

The contribution to theory consists of aspects concerning the integration of macro and micro levels: relationships between normative and prescriptive support, continuous focus shifts, and method completeness.

Practical implications

The contribution to practice consists of explicit suggestions for method support that could be integrated into the ADR method.

Originality/value

This study extends previously provided knowledge by offering empirical evidence concerning theoretical constructions consisting of explicit relationships between ADR tasks and integrated method support, and elaboration on the integration of macro and micro levels.

Abstract

Executive Summary

“The unexamined life is not worth living” (Socrates). That is, without critically inquiring into the knowledge of life which is well-being and valuable, life is not worth living. Critical thinking questions existing theories and their unexamined and obsessive assumptions and generalizations, constraints, and “best” practices of the prevailing system of management and tries to replace them with more valid assumptions and generalizations that uphold the dignity, uniqueness, and inalienable rights of the individual person and the community. Better outcomes result from asking the right questions than from having the right answers. In the diverse, pluralist cultural environment of today, the promise of a truly generative dialog among Occidental (Western) and Oriental (Eastern) cultures and civilizations holds great hope for the future. Critical thinking (CT) is an “inclusive” thinking system that can facilitate this dialog such that all of us have a meaningful space and place in this universe. After defining CT and arguing its importance for executives, this chapter introduces CT in two parts: Part 1: Various Approaches to Critical Thinking; Part 2: Major Theories of Critical Thinking. Several contemporary business cases will be invoked to illustrate the need, nature, and scope of corporate CT.

Abstract

Purpose

Sports leagues have stood out in the entertainment industry due to their great economic value and cultural impact. This is the case of the American sports leagues, with emphasis on the National Basketball Association (NBA), whose largest Latin American market lies on Brazil. The aforementioned league’s audience is constantly growing, a fact that can be partially explained by the encouragement provided for its viewers to interact through social media, in a phenomenon called social TV. Accordingly, the aim of the present study is to investigate how social TV works as a means for Brazilian fans to coproduce their NBA broadcasting enjoyment through social media interactions.

Design/methodology/approach

The authors conducted a netnography on the community of fans engaged in Twitter hashtag #NBAnaESPN, which was released by ESPN to promote audience integration during NBA games' broadcasting.

Findings

A theorization about the role played by social TV in the way fan culture articulates through social media to enjoy broadcasting media products was herein presented. The findings of this study have evidenced three categories concerning the role played by television broadcasting, social media and the fandom in NBA consumption by Brazilian fans. Based on these findings, the authors got to the conclusion that social TV establishes a mediatized environment where fan culture can be articulated through social media to enable interactions about television broadcasting.

Research limitations/implications

The study was limited to members of the Brazilian NBA audience who engage in the official social media of the league’s broadcasting.

Originality/value

The study heads toward a theoretical generalization based on the research results.

Abstract

Purpose

In this paper, the author introduces a degenerate exponential integral function and further studies some of its analytical properties. The new function is a generalization of the classical exponential integral function and the properties established are analogous to those satisfied by the classical function.

Design/methodology/approach

The methods adopted in establishing the results are theoretical in nature.

Findings

A degenerate exponential integral function which is a generalization of the classical exponential integral function has been introduced and its properties investigated. Upon taking some limits, the established results reduce to results involving the classical exponential integral function.

Originality/value

The results obtained in this paper are new and have the potential of inspiring further research on the subject.

Abstract

Purpose

In this paper, we give some properties of the α-connections on statistical manifolds and we study the α-conformal equivalence where we develop an expression of curvature R¯ for ¯ in relation to those for ∇ and ^.

Design/methodology/approach

In the first section of this paper, we prove some results about the α-connections of a statistical manifold where we give some properties of the difference tensor K and we determine a relation between the curvature tensors; this relation is a generalization of the results obtained in [1]. In the second section, we introduce the notion of α-conformal equivalence of statistical manifolds treated in [1, 3], and we construct some examples.

Findings

We give some properties of the difference tensor K and we determine a relation between the curvature tensors; this relation is a generalization of the results obtained in [1]. In the second section, we introduce the notion of α-conformal equivalence of statistical manifolds, we give the relations between curvature tensors and we construct some examples.

Originality/value

Abstract

Purpose

Intrinsic motivation affects job satisfaction and turnover intention. Still, previous motivational studies among real estate brokers (brokers) have primarily focused on extrinsic rewards, leaving intrinsic rewards/motivation practically unexplored. The purpose of this study is therefore to evaluate the role of both satisfaction with intrinsic rewards (SIR) and satisfaction with extrinsic rewards (SER) on job satisfaction and turnover intention among Swedish brokers.

Design/methodology/approach

This article is a replication, more precisely an empirical generalization and extension, of Mosquera et al.’s (2020) study conducted among brokers in Portugal. Using a sample of 910 Swedish brokers, the study analyzes a conceptual framework and tests hypotheses by using partial least squares (PLS).

Findings

Results indicate that SIR has a very strong impact on job satisfaction, which is not the case in the Portuguese sample. On the other hand, SER does not have an impact on job satisfaction, which is the case in the Portuguese sample. SIR does not have an impact on turnover intention in the Swedish sample, whereas SER does. Job satisfaction has twice the positive impact on turnover intention in the Swedish sample compared to the Portuguese. Furthermore, job satisfaction mediates the relationship between SIR/SER and turnover intention.

Research limitations/implications

Findings of this study extend the existing literature of satisfaction with extrinsic and in particular intrinsic rewards on job satisfaction and turnover intention in the context of the brokerage industry. The most interesting difference between the samples is that Swedish brokers display much higher levels of satisfaction with intrinsic rewards. On the other hand, Swedish brokers appear to be less driven by extrinsic rewards, which is not in line with prior studies within brokerage.

Practical implications

Both managers and students planning to become brokers should consider that SIR has a stronger impact on job satisfaction than SER. What are perceived as intrinsic rewards, however, is highly subjective, which is troublesome from a managerial perspective, even more so as SIR is much harder to influence than SER. Given that intrinsic motivation is primarily a consequence of needs fulfillment, screening of applicants for person-job fit ought to increase job satisfaction and reduce turnover given its focus on the congruence between job demands and worker’s needs, respectively, what a job provides and the worker’s needs.

Originality/value

This study contributes to the brokerage research field by indicating that being a broker differs substantially between countries and that intrinsic rewards matter for Swedish brokers.

Abstract

Purpose

The purpose of this paper is to critically evaluate the meaning of being a social entrepreneur in a society marked with multiple transitions. It aims to understand how theoretical concepts of social entrepreneurs, including common dichotomies between economic and social, collective and individual, reflect in social entrepreneurs’ rationale, values and identities.

Design/methodology/approach

The study used an exploratory and qualitative approach. Empirical data were gathered during 14 semi-structured interviews with Croatian social entrepreneurs. Thematic analysis was used as an analytical framework.

Findings

The findings suggest complexity of social entrepreneurs’ rationale and identities as they face challenges in balancing different goals. Democratic and participative governance appeared to be the weakest link of social enterprises. Identity of social entrepreneurs in the society of multiple transitions is fluid and changes through the continuum from pure social to pure commercial, from more related to civil society to more related to the market, from mostly individual to mostly collective.

Research limitations/implications

The main limits of the study are related to sampling strategy and the small sample size. Generalization is limited by the nature of qualitative research and relies on analytical and naturalistic generalization.

Practical implications

The findings of the study may contribute to ecosystem development that would be more suitable for social enterprise realities in a specific context.

Originality/value

This paper focuses on the individual level and provides rare insights into social entrepreneurs’ rationale, values and identities.

Abstract

Purpose

Defence supply chains (SCs) aim at operational outcomes, and armed forces depend on them to provide availability and preparedness in peace and sustainability in war. Previous research has focussed on strategies for SCs aiming at financial outcomes. This raises the question of how suitable commercial supply chain strategies (SCSs) are for supply chain design (SCD) in defence. The purpose of this paper is to explain the constructs of SCSs that satisfy military operational requirements and to propose SCSs that are appropriate in defence.

Design/methodology/approach

This paper reports on a Delphi study with 20 experts from Swedish defence authorities. Through three Delphi rounds, two workshops and a validation round, these experts contributed to the reported findings.

Findings

The findings demonstrate that commercial SC constructs are acceptable and applicable in defence but not sufficient. An additional strategy is required to satisfy requirements on availability, preparedness and sustainability. The paper shows that different requirements in peace and war make it challenging to design suitable defence SCs and proposes eight SCSs that satisfy these requirements.

Research limitations/implications

The results emanate from the Swedish defence context and further research is required for generalisation.

Originality/value

This paper extends theory by investigating SCs aiming at operational outcomes. For managers in companies and defence authorities, it explicates how the unique issues in defence must influence SCD to satisfy operational requirements.
