This study aims to examine the impacts of brand structure (i.e. brand cohesiveness and similarity) on brand perceptions and the adverse effects of brand extensions.

Data were collected online via Amazon Mechanical Turk. Overall, 188 US residents participated in the 2 (extension typicality: typical and atypical) × 3 (brand cohesiveness: high, medium and low) between-subject experimental design.

Narrow brands are favored over cohesive broad brands, and cohesive broad brands are favored over incohesive broad brands. When new extensions are typical, brand cohesiveness dominates brand similarity in terms of adverse extension effects. Negative extension information exerts more salient adverse effects on narrow brands and cohesive broad brands than on incohesive broad brands. Conversely, when new extensions are atypical, brand similarity dominates brand cohesiveness on adverse extension effects. Negative extension information exerts more salient adverse effects on narrow brands than on cohesive and incohesive broad brands.

Brand cohesiveness is more impactful than brand similarity on brand perceptions. The identical adverse effects of typical extensions on narrow, and broad brands exist only when the portfolio products of the broad brands are cohesive.

Cohesive broad brands have the advantages of being more favored than incohesive broad brands and being less vulnerable to negative atypical extension information than are narrow brands.

This study advances brand research by examining the interplay between brand structure (i.e. category cohesiveness and similarity) and extension typicality on adverse extension effects.

The purpose of this paper is to investigate the dominance of athlete endorser characteristics (i.e. moral character vs warmth) on athlete endorser perception and the influence of tarnished athlete endorsers (i.e. immoral character vs coldness) on brand evaluations from the perspectives of perceiver characteristics, including dispositional tendency, innate moral intuitions, and self-location (SL).

This research consists of three experimental studies with 135, 72, and 91 participants, respectively. Study 1 compared the dominance of moral character and warmth on athlete endorser perception. Study 2 examined the impact of perceiver characteristics on the cause-and-effect relationship between tarnished athlete endorsers (i.e. immoral character vs coldness) and brand evaluations. Study 3 investigated the cross-cultural generalizability of the US-based research findings in Study 2 for Indians.

Moral character is more influential than warmth on athlete endorser evaluations. Tarnished athlete endorsers with immoral character exert more negative influence than tarnished athlete endorsers with coldness characteristic on brand evaluations. Except for dispositional tendency, innate moral intuitions and SL moderate brand evaluations. Endorser and perceiver characteristics yield asymmetric patterns of influence on Americans’ and Indians’ brand evaluations.

Future research is needed to verify the causal effects of thinking styles on the relationship between tarnished athlete endorsers and brand evaluations.

The determination of endorsement continuity has to jointly consider the characteristics of endorsers, perceivers, and cultures.

This research contributes to the endorsement research by advancing the research scopes of athlete endorser, perceiver, and culture characteristics.

A new academic structure for senior secondary and higher education was introduced to Hong Kong in 2009/2010. This paper aims to: (1) compare the cohort from the old academic structure (Cohort 2010) and the cohort from the new academic structure (Cohort 2015) on the 14 categories of generic competencies; and (2) compare these attributes among students from different divisions in a tertiary institution in Hong Kong.

Self-Assessment of All-Round Development (SAARD) questionnaires were distributed to students who took the two-year sub-degree programmes offered by the College of Professional and Continuing Education, The Hong Kong Polytechnic University in 2010 and 2015 on a self-administered basis. A total of 4,424 students have returned the questionnaires. Data were analyzed with t-test to compare between the two cohorts.

When comparing Cohort 2015 with Cohort 2010, significantly higher scores were observed on five areas such as global outlook and healthy lifestyle (p<0.05). Significantly lower scores were observed on the other five areas such as problem solving, critical thinking and leadership (p<0.05). Students from all divisions unanimously showed higher perceived rating on social and national responsibility but lower perceived rating on leadership (p<0.05).

The elimination of one public examination, the newly included components such as Other Learning Experiences (OLE) and the compulsory Liberal Studies were believed to contribute partially to the diverse responses of the two cohorts. The dramatic change of the curriculum has not changed the examination culture in Hong Kong which may hinder the development of generic skills among students.

This research is situated at a metropolitan university in Melbourne (Australia) where the authors work in initial teacher education programs within the same faculty. The purpose of this study is to raise awareness that collegial, collaborative and “co-caring” environments can foster an improved sense of belonging, acceptance and inclusion in the academy. They also argue that communities of practice may foster an improved sense of belonging that enhances empowerment and harmony among all staff in academia in pandemic times and beyond.

The authors draw on case study methodology as a qualitative approach to understand and illuminate the phenomena under study. Case study methodology provides an in-depth understanding of their trifocal voices, as it allows them to voice their stories through collaborative autoethnography. The authors use self-narratives to unpack their sense of belonging in academic spaces. Collaborative autoethnography (CAE) enabled them to work together as a team of women and as a community of researchers.

The findings foreground the responsibilities of casual staff while concomitantly articulating the challenges faced by both permanent and casual staff to create a “sense of belonging” in the academy. The authors found that social connection engenders a sense of belonging and inclusion within a space that is often beset by neoliberal ideologies of competitiveness and individual achievement. They articulate their stress, pressure and uncertainty as permanent and as casual academics working supportively to develop and maintain identity in very difficult circumstances. They share how they developed professional relationships which bring unforeseen benefits and personal friendship at a time of especially restrictive practices.

The paper includes three voices, a limitation in itself, thus generalisations cannot be made to other academics or institutions. Employing CAE offers the possibility of delving more deeply into the emotional complexities inherent within this method for further research. They recommend a sense of “co-caring” as a form of pastoral care in the “induction program” for all academics including casual staff. While this may not “strategically” fit in with many because of power imbalances, the journey of co-caring and sharing and building friendships within the academy has a limited presence in the literature and calls for further investigation.

The authors draw attention to the need for higher education institutes to recognise the role permanent staff play when working with casual academics.

The authors draw attention to the need to be inclusive and collaborative as a way to improve the divide and strengthen connections between permanent and casual academics at university worksites. This is imperative given the shifting demographics within Australia and its workforce. They also highlight issues of race in the academy.

This is an original work carried out by the authors. It raises concerns about a sense of belonging in the academy, job certainty and the place of people of colour as these issues may also be experienced by other full-time and casual academics.

The purpose of this paper is to identify how organizations can evaluate the green product deletion decision within an environmentally sustainable consumption and production environment through a hybrid multistage multiple criteria evaluation approach.

This paper proposes a decision-making model by integrating “soft computation” using neighborhood rough set theory, fuzzy cluster means, and cumulative prospect theory. Literature is used to identify various factors for the decision environment. An illustrative problem provides insights into the methodology and application.

The results indicate that green products can be evaluated from both their relative environmental burdens and benefits. Sustainable consumption and production factors that play a role in this multifactor decision are identified. The results show that a comprehensive evaluation can capture an effective overall picture on which green product(s) to delete.

The opaqueness of the proposed methodology may cause less acceptance by management. The methodology made a number of assumptions related to the data. An actual application of the tool rather than just an illustrative example is needed.

The main contribution of this study is the novel integration of supply chain perspectives, both upstream (supply and production) and downstream (demand/usage), with green product deletion decision making. The hybrid multistage technique has advantages of being able to incorporate many factors that have a variety of quantitative and qualitative characteristics to help managers address green product deletion issues as well as its impact on greening of supply chains and organizational environmental sustainability. This paper adds value to product deletion, supply chain management, and sustainable production and consumption literatures.

This paper aims to shed light on an essential role that “female directors” on boards of companies in sub-Saharan Africa play towards corporate financial performance enhancement. The study observes how board gender diversity moderates the relationship between earnings management (EM) and financial performance of firms in sub-Saharan Africa from a dynamic perspective.

The study’s sample comprises 105 companies listed on the respective stock markets of nine sub-Saharan African countries. The data are collected from annual reports over the period 2007–2019, a total of 1,166 firm-year observations. Panel data models are used in the analyses.

The study finds that the performance effect of EM is contingent on board diversity and this finding persists even after controlling for dynamic endogeneity, simultaneity and unobserved time-invariant heterogeneity inherent in the EM and performance relationship.

The findings should be understood within the context that, only available annual reports and audited financial statements that were filed with respective capital markets of the nine surveyed countries are used as source of information.

The current study is unique, in that, it is the first panel multi-cross-country investigation within Africa to introduce gender diversity in the study of the relationship between EM and firm performance. It therefore extends the agency theory by using gender diversity as a moderating variable in the EM–firm performance nexus.

This study aims to evaluate blast loads on and the response of submerged structures.

An arbitrary Lagrangian–Eulerian method is developed to model fluid–structure interaction (FSI) problems of close-in underwater explosions (UNDEX). The “fluid” part provides the loads for the structure considers air, water and high explosive materials. The spatial discretization for the fluid domain is performed with a second-order vertex-based finite volume scheme with a tangent of hyperbola interface capturing technique. The temporal discretization is based on explicit Runge–Kutta methods. The structure is described by a large-deformation Lagrangian formulation and discretized via finite elements. First, one-dimensional test cases are given to show that the numerical method is free of mesh movement effects. Thereafter, three-dimensional FSI problems of close-in UNDEX are studied. Finally, the computation of UNDEX near a ship compartment is performed.

The difference in the flow mechanisms between rigid targets and deforming targets is quantified and evaluated.

Cavitation is modeled only approximately and may require further refinement/modeling.

The results demonstrate that the proposed numerical method is accurate, robust and versatile for practical use.

Better design of naval infrastructure [such as bridges, ports, etc.].

The study reported on in this article examines how instructional leadership is exercised by superintendents in effective school districts. We employ concepts drawn from school effectiveness studies and from organizational literature on coordination and control in an attempt to understand how superintendents organize and manage instruction and curriculum in these effective districts. Specific instructional management practices are examined within a framework of six major functions, setting goals and establishing expectations and standards, selecting staff, supervising and evaluating staff, establishing an instructional and curricular focus, ensuring consistency in technical core operations, and monitoring curriculum and instruction. Based on interviews with superintendents from 12 of the most instructionally effective school districts in California and analysis of selected district documents, we present descriptions of district‐level policies and practices that these superintendents use to coordinate and control the instructional management activities of their principals. Similarities and differences in the patterns of control and coordination found in these districts are highlighted. The implications of the findings are then examined in light of recent findings regarding coupling and linkages in schools. The results of this study suggest that superintendents in instructionally effective school districts are more active “instructional managers” than previous descriptions of superintendents would have led us to expect. In particular, coordination and control of the technical core appears more systematic in these districts. The results do not, however, provide a uniform picture of how instruction is coordinated and controlled. A wide range of both culture building activities and bureaucratic policies and practices were emphasized by the superintendents in this study as they exercised their instructional leadership roles.

This study aims to investigate affective commitment (ACS) and leader–member exchange (LMX) as resources mitigating against burnout and counterproductive work behaviours (CWBs) in the hospitality sector, and examines the effect of zero-hour contracts on these relationships.

Through conservation of resources theory, this study tests a framework exploring ACS and LMX as resources against burnout and CWBs, using a data set of 260 frontline hospitality employees working in Ireland, considering zero-hour contracts as a moderator.

Findings indicate that burnout is associated with CWB, and ACS and LMX are resources against burnout and CWB. Furthermore, zero-hour contract perceptions moderate the resource effect of ACS and LMX. Yet, zero-hour contract perceptions do not moderate the relationship between burnout and CWB, indicating these employees may be caught in a resource-loss spiral.

This study proposes mechanisms to enhance resources against burnout, with specific strategies to support young employees who are more likely to experience burnout. As findings suggest unique negative impacts of burnout for employees on zero-hour contracts, this paper also provides guidance to support these vulnerable employees.

This study provides unique insights into hospitality employees’ ability to harness resources against burnout and CWB consequences of burnout. The results indicate that perceived precarity does not moderate these relationships, suggesting that burnout affects this cohort differently.
