This paper aims to clarify the relationship between mechanical behaviors and the underlying geometry of periodic cellular structures. Particularly, the answer to the following research question is investigated: Can seemingly different geometries of the repeating unit cells of periodic cellular structure result in similar functional behaviors? The study aims to cluster the geometry-functional behavior relationship into different categories.

Specifically, the effects of the geometry on the compressive deformation (mechanical behavior) responses of multiple standardized cubic periodic cellular structures (CPCS) at macro scales are investigated through both physical tests and finite element simulations of three-dimensional (3D) printed samples. Additionally, these multiple CPCS can be further nested into the shell of 3D models of various mechanical domain parts to demonstrate the influence of their geometries in practical applications.

The paper provides insights into how different CPCS (geometrically different unit cells) influence their compressive deformation behaviors. It suggests a standardized strategy for comparing mechanical behaviors of different CPCS.

This paper is the first work in the research domain to investigate if seemingly different geometries of the underlying unit cell can result in similar mechanical behaviors. It also fulfills the need to infill and lattify real functional parts with geometrically complex unit cells. Existing work mainly focused on simple shapes such as basic trusses or cubes with spherical holes.

Jarring events, be they global crises such as COVID-19 or technological events such as the Cambridge Analytica data incident, have bullwhip effects on billions of people's daily lives. Such “shocks” vary in their characteristics. While some shocks cause, for example, widespread adoption of information systems (IS) as diverse as Netflix and Teams, others lead users to stop using IS, such as Facebook. To offer insights into the multifaceted ways shocks influence user behavior, this study aims to assess the status quo of shock-related literature in the IS discipline and develop a taxonomy that paves the path for future IS research on shocks.

This study conducted a literature review (N = 70) to assess the status quo of shock-related research in the IS discipline. Through a qualitative study based on users who experienced shocks (N = 39), it confirmed the findings of previous literature in an illustrative IS research context. Integrating the findings of the literature review and qualitative study, this study informs a taxonomy of shocks impacting IS use.

This study identifies different ways that shocks influence user behavior. The taxonomy reveals that IS research could profit from considering environmental, private and work shocks and shedding light on positive shocks. IS research could also benefit from examining the urgency of shocks, as there are indications that this influences how and when individuals react to a specific shock.

Findings complement previous rational explanations for user behavior by showing technology use can be influenced by shocks. This study offers a foundation for forward-looking research that connects jarring events to patterns of technology use.

Not many weeks back, according to newspaper reports, three members of the library staff of the School of Slavonic and East European Studies in London were dismissed. All had refused to carry out issue desk duty. All, according to the newspaper account, were members of ASTMS. None, according to the Library Association yearbook, was a member of the appropriate professional organisation for librarians in Great Britain.

The purpose of this research was to test the influence of consumer knowledge management on attitudinal and behavioral loyalty through service quality and psychological involvement.

The participants (N = 396) were recruited through a convenience sampling technique from non-profit sport clubs in Iran. Data were analyzed with the Structural Equation Modeling using Mplus 7.4.

The results revealed that the effects of service quality on psychological involvement were dependent on consumer knowledge management. Furthermore, there were the mediating effects of service quality and psychological involvement in the relationships between the consumer knowledge management and loyalty.

The research findings provide valuable insights for non-profit sport club managers seeking to better attract and retain their consumers by demonstrating the importance of investing in consumer knowledge management initiatives. Managers should thus integrate knowledge orientation into their marketing and relationship management strategies and apply the strategy into consumer knowledge within club services.

This study empirically highlights the important role of knowledge from, for and about the consumer on perceived service quality and loyalty building among the non-profit consumer base.

The aim was to assess the quality of newspaper reporting of university student suicides in South Africa, using the World Health Organisation guidelines. Suicide among university students is a growing public health problem. The media has an important role to play in preventing student suicides by adhering to international best practice guidelines on ethical reporting of suicides.

This study conducted a content analysis of print medium newspaper articles in the 13 most widely read English language South African newspapers from the period of January 2017 to January 2020.

The initial search yielded a total of 28 news reports, of which 19 met this study’s inclusion criteria and were analysed using content analysis. The quality of reporting showed both potentially harmful and helpful characteristics. Poor adherence to international reporting guidelines were found in the description of method and location of suicide, sensational headlines, publishing photos of the deceased, linking suicide to criminality, simplistic narration of the life events leading to the suicide and use of sensational and potentially triggering language. No reports adhered to all reporting guidelines. Findings suggests that there are widespread potentially unhelpful practices in the reporting of student suicides and a need for suicide prevention experts to work with journalists to promote critical reflexivity and ethical reasoning when writing about student suicides.

This study only included news reports published in English in the most widely read newspapers.

To the best of the authors’ knowledge, this is the first study of its kind to systematically examine media reporting on suicide in South Africa.

This paper unravels the conceptual and theoretical insights of Foucault’s later work on technologies of self in order to understand Bio‐medicine which impinges on the social construction of ageing. The article attempts to show how Foucault’s theoretical insights allows scholars of sociology and social policy to provide a critical appraisal of ageing. The paper also examines the relationship between ageing and self‐care in three contextual domains: good health management; use of counselling; and bodily enhancement.

SUITABILITY of materials and their usage can be a profitable source of investigation for the methods engineer. And an important function too, for it implies not only an examination of the most suitable material in relation to the product to be processed, but also, methods of storage, inspection, and the economic utilisation of that material at all stages. Any of these aspects involves a major investigation if the firm is interested in discovering untapped sources of economy. It is one of the avenues not often explored by work study, but there is no valid reason why it should remain a sort of no‐man's‐land.

The purpose of this study is to examine the relationship between psychiatric severity and stress among persons utilizing medication assisted treatment (MAT), and there is a need to identify resources that promote resilience against these risk factors. Although recovery homes might complement pharmacological interventions for persons using MAT, a lack of homophily (e.g. similar experiences) among residents could produce stress and increase psychiatric severity. The purpose of this paper is to examine stress and psychiatric severity in relation to recovery outcomes, and whether homophily moderated these relationships.

A cross-sectional analysis was conducted among recovery home residents who were recruited from the USA, including those using (n = 40) and not using (n = 132) MAT. Participants’ levels of psychiatric severity, stress, abstinence self-efficacy and quality of life were assessed in addition to whether residents using MAT were living with at least one other resident who used MAT. Moderated mediation analyses were conducted to examine whether homophily among residents using MAT would moderate the mediating effects of stress on the relationships between psychiatric severity and recovery outcomes (abstinence-self efficacy, quality of life).

Mediating effects were observed but they were significant only through homophily. Although stress increased the negative effects of psychiatric severity among residents using MAT, significantly lesser effects were observed among those living with residents using MAT.

Although psychiatric (problem) severity and stress threaten recovery for persons with substance use disorders, little is known how they impact recovery among those living in community-based settings such as recovery homes. In addition, there is a need to identify community resources that would complement MAT protocols, as patients who use MAT face unique stressors related to their sense of shared interests and experiences (i.e. homophily) when developing social bonds with others in recovery.

This study suggests the social networks within recovery homes reduce the effects of psychiatric severity and stress, and that these effects are lessened for residents who use MAT when they live with others who also use MAT.

Little is known about recovery home residents who use MAT and have high psychiatric severity. Findings suggest homophily among persons using MAT living in recovery homes who have high psychiatric severity can promote resilience.

The aim of this paper is to examine when it is appropriate to provide dedicated support for a sales activity, and in cases where support is desirable, to explore the choice between core team support and external support.

Sales transactions typically require a diverse range of sales activities, including customer contact, scheduling appointments, internal meetings, processing orders, and preparing financing applications. This research develops a framework for understanding how to structure sales support for specific sales activities.

Each sales activity has four dimensions, i.e. workload, customization, complexity, and prequalification risk. Support structure (self‐support, core team support, and external support) moderates the influence of the four sales activity dimensions on sales activity performance and salesperson role stress. These, in turn, impact overall sales performance.

This research presents a broad conceptual model of sales support structure. Further research should test this framework using empirical data.

Normative recommendations are made for managers about how to allocate sales activities to sales support.

This research proposes four relevant dimensions of sales activities that should be considered when allocating sales activities to members of the selling center. The framework will help managers, academicians, and business students understand how sales support structure impacts sales performance.

This paper aims to examine how Chief Executive Officer (CEO) power affects firm-level labor productivity.

The authors rely on regression analysis to examine the relation between CEO power and labor productivity.

Following prior research (i.e. the sequential rank order tournament theory), the authors predict that powerful CEOs lead to high labor productivity. They find a significant and positive relationship between CEO power and labor productivity. They further decompose labor productivity into labor efficiency and labor cost components and find a positive (negative) relationship between CEO power and labor efficiency (cost) component, suggesting that more powerful CEOs better manage labor efficiency and control labor cost. The results are also robust to various additional tests.

This study contributes to two streams of research: the CEO power literature in finance and the labor productivity and cost literature in accounting. To the best of the authors’ knowledge, it is the first study that performs a direct empirical test on the relation between CEO power and labor productivity.
