Purpose From a social capital perspective, this study aims to shed light on the link between social capital and career adaptability by focusing on how social connections and interactions shape and nurture career adaptability. Drawing on socioemotional selectivity theory, the authors further examined the critical moderating role of age on the above relationship. Design/methodology/approach Survey responses from 208 HRD professionals were analyzed via a moderated mediation analysis. Findings The results showed that there is a positive relationship between social capital (network size and intimate network) and career adaptability; frequent interaction increases intimacy, in turn enhancing career adaptability; and the indirect effect of social capital on career adaptability (via intimate network) is stronger when the employee is younger. Originality/value The most novel theoretical contribution of this study is that the authors lend empirical support to the connection between social capital and career adaptability moderated by age. The study also contributes to understanding how core aspects of social capital are inter-related each other and have directional relationships.

PurposeDrawing on the signaling theory and technology acceptance model, the main purpose of this study was to predict prospective employees' intentions to apply for jobs in a firm, with a special focus on the mediating role of attitudes toward corporate websites and the moderating role of perceived value fit.Design/methodology/approachCollecting data from a convenient sample of 318 prospective job candidates, the research hypotheses were tested using structural equation modeling (SEM) with AMOS (version 24) and SPSS Process Macro (version 3.4).FindingsThe test results revealed that prospective employees' attitudes toward corporate websites partially mediate the association of corporate reputations, perceived ease of use and perceived usefulness with their intentions to apply for jobs in an organization. Noticeably, perceived value fit moderated the perceived usefulness–application intentions link in such a way that the impact of perceived usefulness on intentions to apply appears higher for individuals with a low level (than a high level) of perceived value fit.Research limitations/implicationsConsistent with the research findings, a notable theoretical contribution and practical implications for HR professionals have been discussed. This paper ends with outlining some limitations and future research directions.Originality/valueDespite having the salient buffering effects of perceived value fit on the applicant attraction process, empirical study on this theoretical phenomenon is still sparse in a pre-employment context. This may be the first study that demonstrates under what circumstances prospective employees' job pursuit intentions could be optimized in respect of their perceived value fit within a single framework comprised of two theories.

Copper–tin alloys are widely used in the machining and molding of sleeves, bearings, bearing housings, gears, etc. They are a material used in heavy-duty, high-speed and high-temperature situations and subject to strong friction conditions due to their high strength, high modulus of elasticity, low coefficient of friction and good wear and corrosion resistance. Although copper–tin alloys are excellent materials, a higher performance of mechanical parts is required under extreme operating conditions. Plastic deformation is an effective way to improve the overall performance of a workpiece. In this study, medium-temperature compression tests were performed on a semi-solid CuSn10P1 alloy using a Gleeble 1500D testing machine at different temperatures (350−440 °C) and strain rates (0.1−10 s−1) to obtain its medium-temperature deformation characteristics. The experimental results show that the filamentary deformation marks appearing during the deformation are not single twins or slip lines, but a mixture of dislocations, stacking faults and twins. Within the experimental parameters, the filamentary deformation marks increase with increasing strain and decrease with increasing temperature. Twinning subdivides the grains into lamellar sheets, and dislocation aggregates are found near the twinning boundaries. The results of this study are expected to make a theoretical contribution to the forming of copper–tin alloys in post-processing processes such as rolling and forging.

During a flight, changes occur in the human body, whose possible reactions can influence the well-being and quality of health of medicine users, subject of scarce studies. The aim of this paper is to analyze the impacts and effects of medication use during air transport. Through a literature review and documentary research methodology, relevant facts about the precautions that should be taken regarding the use of medication in flights were considered. As a practical contribution, some important medications and their possible effects during flights are presented, as well as some warnings about medication interactions, and some advice for better quality air travel for the health of passengers and crew are given. As a theoretical contribution, this study gathers the scattered information presented in the literature about the problems that the use of medications during a flight can cause to the human body and possible recommendations. As social contribution, this study warns about the risks of self-medication, and establishes a basis for future discussions with society about the use of medication in flights.

The evaporation of multiple sessile droplets is both scientifically interesting and practically important, occurring in many natural and industrial applications. Although there are simple analytic expressions to predict evaporation rates of single droplets, there are no such frameworks for general configurations of droplets of arbitrary size, contact angle or spacing. However, a recent theoretical contribution by Masoud, Howell & Stone (J. Fluid Mech., vol. 927, 2021, R4) shows how considerable insight can be gained into the evaporation of arbitrary configurations of droplets without having either to obtain the solution for the concentration of vapour in the atmosphere or to perform direct numerical simulations of the full problem. The theoretical predictions show excellent agreement with simulations for all configurations, only deviating by 25 % for the most confined droplets.

AbstractEmissions from road traffic contribute to climate change. One approach to reducing the carbon footprint is providing eco-driving feedback so that drivers adapt their driving style. Research about the impact of eco-feedback on energy consumption is the basis for designing a mobile eco-driving feedback information system that supports drivers in reducing fuel consumption. This work develops design knowledge from existing knowledge. Subsequently, we implement a prototypical instantiation based on the derived knowledge. Insights from a field study suggest that our design artifact allows most drivers to decrease fuel consumption by 4% on average. The paper’s theoretical contribution is a set of design principles and an architecture of the proposed mobile eco-driving feedback information system. One recommendation is to provide normative feedback that compares drivers with each other. This feedback appears to encourage drivers to decrease their fuel consumption additionally. The design knowledge may support researchers and practitioners in implementing efficient eco-driving feedback information systems.

The purpose of this study was to explore perceptions of the benefits and challenges experienced by community and allotment gardens utilising a broad theoretical analysis, pertaining to the case study of Melbourne, a city in Australia that until recently has been experiencing significant population growth and urban densification. The study involved qualitative, semi-structured interviews with 23 participants from six urban community and allotment gardens. Interviews identified the perceived benefits of community and allotment gardening, perceived demographic patterns of engagement, challenges faced in relation to secure land access, and the potential offered by community and allotment gardens for social and environmental wellbeing. Findings revealed a range of perceived benefits, perceived demographic patterns, highlighted challenges posed to participation due to insecurity around ongoing land access, and detailed the perceived capacity community and allotment gardens have to contribute to social and environmental wellbeing. This study contributes to existing literature focused on the benefits and potential of community and allotment gardening for personal, social and environmental wellbeing, by offering an original theoretical contribution through carrying out an analysis informed by urban geography, phenomenology, political economy and ecology, and to literature focused on issues of access to land for these amenities.

This study intends to utilize eye tracking for the appearance of a robot, which is one of the trends in social robot design research. We suggest a research model with the entire stage from the consumer gaze response to the perceived consumer beliefs and further their attitudes toward social robots. Specifically, the eye tracking indicators used in this study are Fixation, First Visit, Total Viewed Stay Time, and Number of Revisits. Also, Areas of Interest are selected to the face, eyes, lips, and full-body of a social robot. In the first relationship, we check which element of the social robot design the consumer’s gaze stays on, and how the gaze on each element affects consumer beliefs. The consumer beliefs are considered as the social robot’s emotional expression, humanness, and facial prominence. Second, we explore whether the formation of consumer attitudes is possible through two major channels. One is the path that the consumer beliefs formed through the gaze influence their attitude, and the other is the path that the consumer gaze response directly influences the attitude. This study made a theoretical contribution in that it finally analysed the path of consumer attitude formation from various angles by linking the gaze tracking reaction and consumer perception. In addition, it is expected to make practical contributions in the suggestion of specific design insights that can be used as a reference for designing social robots.

This study aims to examine the antecedents of storytelling and intention to a behavioral robot barista coffee shop (RBCS) by exploring experiential values and emotions. For the analysis, a set of hypotheses was developed and tested based on data collected from 300 customers who had visited a RBCS in South Korea. In the verification, the atmosphere showed the greatest influence on positive emotion, followed by consumer return on investment (CROI). These results mean that atmosphere, CROI, and escapism are important to induce positive emotion and behavioral intention for robot barista coffee shop. This is the first study to examine consumers’ experiential value regarding non-face-to-face robot service in the food service industry. This design is different from previous experiential value studies on human services in the hospitality industry. By integrating artificial intelligence and digital innovation into food service, this study broadens the scope of research in consumer behavior, making a significant theoretical contribution to the literature. Furthermore, this study proposes practical implications for sustainable coffee shop management in a COVID-19 environment.

Purpose: To receive the answers to the following research problems: (1) How is the interest of researchers in whistleblowing in health care organizations developing? (2) How do researchers define whistleblowing in health care? (3) What are the main problems (limitations) of whistleblowing in health care organizations? (4) What factors affect whistleblowing in health care organizations? Design/methodology/approach: The method of systematic literature review based on the PRISMA model was used. To identify the factors affecting whistleblowing, McKinsey’s 7S framework was used. Findings: The researchers from the UK definitely dominate, and the papers from Central European countries seem to be invisible. The vast majority of works came from the 2010s. Whistleblowing serves the good and safety of the patient; however, there are staff concerns about the consequences they may face. ‘Style’, ‘staff’ and ‘shared values’ seem to be the most crucial for whistleblowing, and these are factors considered ‘soft’. Research limitations: The access to databases managed by the home University. In future studies, there is a need to take into account other databases, including additional sources of knowledge, like books and grey literature. Originality/implications: Identifying the state and place of research worldwide on whistleblowing in health care, and a proposal of the whistleblowing verification matrix. New definitions of whistleblowing and whistleblowers were proposed. The above may be considered theoretical contribution to science.
