Abstract

Purpose

The purpose of this paper is to reshape a fast-jet electronics pod’s external geometry to ensure compliance with aircraft pylon load limits across its carriage envelope while adhering to onboard system constraints and fitment specifications.

Design/methodology/approach

Initial geometric layout determination used empirical methods. Performance approximation on the aircraft with added fairings and stabilising fin configurations was conducted using a panel code. Verification of loads was done using a full steady Reynolds-averaged Navier–Stokes solver, validated against published wind tunnel test data. Acceptable load envelope for the aircraft pylon was defined using two already-certified stores with known flight envelopes.

Findings

Re-lofting the pod’s geometry enabled meeting all geometric and pylon load constraints. However, due to the pod's large size, re-lofting alone was not adequate to respect aircraft/pylon load limitations. A flight restriction was imposed on the aircraft’s roll rate to reduce yaw and roll moments within allowable limits.

Practical implications

The geometry of an electronics pod was redesigned to maximise the permissible flight envelope on its carriage aircraft while respecting the safe carriage load limits determined for its store pylon. Aircraft carriage load constraints must be determined upfront when considering the design of fast-jet electronic pods.

Originality/value

A process for determining the unknown load constraints of a carriage aircraft by analogy is presented, along with the process of tailoring the geometry of an electronics pod to respect aerodynamic load and geometric constraints.

Abstract

Leaders are important social actors in organizations, centrally involved in establishing and maintaining institutional values, a view that was articulated by Philip Selznick (1957) nearly a half-century ago, but often overlooked in institutionalists’ accounts. Our objective is to build on Selznick’s seminal work to investigate the value proposition of leadership consistent with institutional theory. We examine public interview transcripts from 52 senior executives and discover that leaders’ conceptualizations of their entities align with the archetypes of organization (i.e., economic, hierarchical, and power oriented) and institution (i.e., ideological, creative and collectivist) and cohere around a set of relevant values. Extrapolating from this, we advance a theoretical framework of the process whereby leaders’ claims function as transformational mechanisms of value infusion in the institutionalization of organizations.

Abstract

This paper describes the forms of knowledge used by players of fantasy sports, games where players create ideal sports teams and compete to accumulate points based on professional athletes’ statistical performances. Messages from a discussion forum associated with a popular fantasy basketball game were analyzed to understand how players described their decision‐making strategies to their peers. The focus of the research was to understand if players use mathematical concepts such as optimization and statistical analyses when assembling their team or if they base their decisions on personal preferences, beliefs, and biases. The analyses in this paper suggest the latter, that players rely on informal, domain‐specific heuristics that often lead to the creation of competitive teams. These heuristics and other forms of player discourse related to knowledge use are described. The paper also suggests ways that analyses of existing practices might provide a foundation for creating gaming environments that assist the acquisition of more formal reasoning skills.

Abstract

The purpose of this article is to provide organized, synthesized information related to initiatives throughout the world based on knowledge‐based development (KBD) such as knowledge cities (KCs), knowledge regions, and knowledge countries. A first search was conducted using the Internet and specialized databases under the keywords “knowledge cities”. The information compiled led to other related keywords which branched out the search. All resulting information was then collated and integrated into a number of categories all unified under the field of knowledge‐based development. A compilation of information on the topic “knowledge cities” and other topics related to knowledge‐based development. The information is presented in eight sections: a glossary of KC‐related terms, a list of knowledge‐based development initiatives, a list of associations and organizations related to the topic, a list of urban KBD‐related value dimensions and their indicators, a list of international rankings, a list of special editions on KCs, a bibliography, and a directory of related sites on the Internet. This effort resulted in a public service available at the World Wide Web. The information included in this compilation is limited mainly to public domain information available throughout Internet in both English and Spanish, as well as in selected databases.

Abstract

This essay focuses on institutional leadership in complex public organizations. Using an expanded version of James A. Stever’s organizational scepticism framework, an argument is presented that the concept new occupies a privileged and unique position in the modern conception of leadership. The concept’s status is due, in part, to its intimate relationship with other favorable concepts, most notably progress and radical change. It is argued that the modern fixation with new, progress and radical change is troublesome. The scholarly community is encouraged to commit more intellectual resources to developing alternative models of leadership that recognize the usefulness of, but are not limited by, the underlying values and assumptions of modernity. The model of administrative conservatorship is offered as one such model.

Abstract

The writer of a review article in the IT area depends on a variety of information sources containing authoritative material, hyped‐up reports, or even partial or pure fiction. Sometimes articles are biased or the author has a particular axe to grind — for instance the person is associated with a company and the article is no more than a dressed up sales piece. Academics are usually reliable — although unlikely to damn themselves with faint praise if the next grant is round the corner. I will try to exercise good judgement when assessing my information sources, supressing my various prejudices if possible. But what is meant by the word new? For the purposes of this article ATM (Asynchronous Transfer Mode) protocol (rules) and ATM switches in broadband networks, and aspects of Cable‐TV and cable modems have received a lot of exposure. They will not be discussed here. However, there is much interest in the contest between fibreoptic systems to the home and the conversion of telephone lines to wideband lines. These topics will be discussed.

Abstract

Purpose

Trans women of color contend with multiple marginalizations; the purpose of this study is to examine associations between experiencing discriminatory (racist/transphobic) events and depression symptoms. It uses a categorical measure of combined discrimination, and examines a protective association of transgender identity on depression symptoms.

Design/methodology/approach

Data from a subset of trans women of color participants in the Sheroes study were analyzed with linear and logistic regression. Associations of depression symptoms with racist and transphobic events, combined discrimination, coping self-efficacy, and transgender identity were assessed with odds ratios.

Findings

Exposure to discriminatory events and combined discrimination positively associated with depression symptom odds. Increased transgender identity associated with increased coping self-efficacy, which negatively associated with depression symptom odds.

Research limitations/implications

Cross-sectional study data prohibits inferring causality; results support conducting longitudinal research on discrimination's health effects, and research on transgender identity. Results also support operationalizing intersectionality in health research. The study's categorical approach to combined discrimination may be replicable in studies with hard to reach populations and small sample sizes.

Practical implications

Health programs could pursue psychosocial interventions and anti-discrimination campaigns. Interventions might advocate increasing participants’ coping self-efficacy while providing space to explore and develop social identity.

Social implications

There is a need for policy and health programs to center trans women of color concerns.

Originality/value

This study examines combined discrimination and identity in relation to depression symptoms among trans women of color, an underserved population.

Abstract

Purpose

The purpose of this paper is to document the manner in which a pro‐poor company can deliver ongoing health benefits and improve environmental sustainability in a manner that addresses child and maternal mortality (in line with millennium development goals 4, 5 and 7).

Design/methodology/approach

Field research in Mozambique including 12 in‐depth interviews with key personnel from December 2006 to January 2007.

Findings

First, clear threats to the success of VidaGás' pro‐poor business model encompass insufficient liquefied petroleum gas (LPG) supply and storage facilities; poor industrial and commercial infrastructure in Northern Mozambique; inadequate training of retailers in LPG use; and inadequate consumer knowledge of the benefits of LPG. Second, key innovations employed by VidaGás to overcome these obstacles consist of the introduction of a novel cold chain to safeguard medicines; a complex supply chain to ensure timely delivery; and the exploitation of local knowledge and expertise to expand the uptake of LPG by Mozambicans.

Practical implications

The case study focuses on a business problem with significant development implications. The challenge is to ensure a reliable supply of LPG in Northern Mozambique. To meet this challenge, VidaGás must achieve its stated goal of becoming a revenue‐generating entity within three years. In order to create a viable market for LPG, VidaGás must not only increase the uptake of LPG by poor consumers, it must expand LPG market access to commercial consumers, while raising additional capital.

Originality/value

The paper contributes to the literature on social entrepreneurship and demonstrates how to link for‐profit business imperatives with development goals.

Abstract

Purpose

The purpose of this systematic review is to highlight some of the business model changes restaurants, bars and beverage producers undertook to modify their operations in order to not only stay in business but also to better serve their employees and communities during the COVID-19 crisis.

Design/methodology/approach

An analysis was conducted on 200 industry articles and categorized into three major themes: expansion of take-out/delivery, innovative practices, and community outreach/corporate support, each are further subdivided into additional themes. The systematic review is further supported by personal interviews with industry professionals.

Findings

This research finds that there were many different approaches used in adjusting business models in response to the dining restrictions put in place due to COVID-19. From these approaches, themes were developed which resulted in uncovering some suggestions such as developing contingency plans, being flexible and creative, eliminating menu items, investing in a communication platform and getting involved with local government. In addition, some practices operators should be mindful of such as selling gift cards and starting a crowdfund.

Research limitations/implications

This research provides a systematic analysis of business model changes that occurred due to COVID-19 dining restrictions. Researchers can use this information as a guide for further analysis on a specific theme introduced herein.

Practical implications

This research offers several practical implications which will assist the industry should another similar event occur in the future. The systematic analysis describes and documents some suggestions as well as practices to be mindful of in preparing contingency plans for the future.

Originality/value

This research documents an unprecedented time for the hospitality industry by examining how restaurant, bar and beverage producers around the country responded to COVID-19 restrictions. Distilling the multitude of information into succinct themes that highlight the business model changes that occurred will aid future research as well as operators.
