The current study builds on social identity theory and realistic conflict theory aims to identify the relationships amongst consumers' ethnocentrism, animosity, discomfort with differences – a factor of universal-diverse orientation (UDO) – and reluctance to purchase German (RELG) and French automobiles (RELF) in the Turkish automobile market which is dominated by foreign brands.

Empirical data were collected via face-to-face surveys from 400 respondents in the emerging market Turkey. Structural equation modelling was employed to examine the direct and indirect effects between the variables.

The main predictors of the RELG are consumer ethnocentrism, discomfort with differences and economic animosity towards Germany, respectively. Furthermore, RELF in the Turkish market is positively affected by consumer ethnocentrism, war animosity towards France and discomfort with differences, respectively. Discomfort with differences mediates the relationship between consumer ethnocentrism and RELG and RELF.

International collaborations with local manufacturers have huge strategic impacts when establishing reliable relationships with Turkish consumers. Foreign companies can initiate socially responsible projects that will relay the message of similarities between cultures to decrease perceived cultural differences. Highlighting the similarities of Turkish consumers with a foreign company in promotional campaigns will be much beneficial.

Despite there are many studies regarding antecedents and consequences of consumer ethnocentrism, extant research overlooks the effect of animosity on this concept. Additionally, studies examining UDO in the marketing literature are scarce. This paper integrates UDO, consumer ethnocentrism, animosity and reluctance to purchase foreign products in one study.

The pharmaceutical industry is one of the most essential areas of health in any country. It is defined as a system of processes, operations and organizations involved in discovering, developing and producing drugs. The supply chain in the pharmaceutical field is one of the most important strategic issues in the pharmaceutical and health-care industries. The purpose of this study is to reduce the total cost of the supply chain network and reduce the amount of distribution scheduling.

In this study, the authors designed a drug supply chain network with uncertainty-related corruption. The optimal number and location of potential facilities, the optimal allocation of flow between facilities, the optimal routing of vehicles and the optimal amount of inventory in production and distribution center warehouses were determined to achieve these two objective functions.

In evaluating the small sample size problem, it was found that the comprehensive benchmarking method was more efficient than the other methods in obtaining the mean index of the first objective function. The utility function method has also proved its efficiency in obtaining the mean of the second objective function indices, the spacing index and the computational time. Because of the inefficiency of GAMS software in resolving size issues, the modified NSGA II and MOPSO algorithms with modified priority-based encryption have been used. First, using the Taguchi method, the initial parameters of the metaheuristic algorithms are adjusted, and then, 15 sample problems are designed in larger sizes. To avoid generating random data, five problems were equally designed, and the averages of objective functions and metrics of met heuristic algorithms (number of efficient solutions, maximum expansion index, spacing index and computational time) were analyzed as the basis of evaluation and comparison. Therefore, using all the indicators and results of the NSGA II algorithm is recommended.

In this research, a biobjective modeling approach is proposed to minimize the total costs of the supply chain network (construction costs, storage costs and product transportation costs between centers) and advertising costs and to minimize distribution and transportation scheduling across each level of the supply chain network.

This study aims to adapt and validate the need satisfaction and frustration scale (NSFS) for the Brazilian gig work context and investigate the distinctiveness of the constructs of basic needs satisfaction and frustration among Brazilian gig workers.

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted on a sample of 351 Brazilian gig workers.

Results from EFA supported a three-factor structure, while results from CFA psychometrically supported a six-factor correlated model. The items that constitute the NSFS presented good discriminant validity (heterotrait-monotrait ratio) and internal consistency (Cronbach’s alpha and McDonald’s omega coefficients). Results regarding criterion validity partially support previous empirical evidence that considers needs satisfaction and frustration independent in relation to well-being and ill-being while reinforcing the need for further investigations. The Brazilian version of the NSFS is shown to be an instrument with robust psychometric qualities to assess workers’ perception of basic needs satisfaction and frustration in Brazilian gig work context.

This study broadens the scope of research on basic psychological needs by introducing a valid and reliable instrument to assess workers’ perceptions of needs satisfaction and frustration in the Brazilian gig work context, a population that has been neglected in self-determination theory research.

O presente estudo teve como objetivos (1) adaptar e validar a Need Satisfaction and Frustration Scale para o contexto brasileiro de gig work e (2) investigar a distinção dos construtos de satisfação e frustração das necessidades básicas entre os trabalhadores gig brasileiros.

A análise fatorial exploratória (AFE) e a análise fatorial confirmatória (AFC) foram realizadas em uma amostra de 351 trabalhadores gig brasileiros.

Os resultados da EFA apoiaram uma estrutura de três fatores, enquanto os resultados da AFC apoiaram psicometricamente um modelo correlacionado de seis fatores. Os itens que constituem a NSFS apresentaram boa validade discriminante (razão heterotraço-monotraço) e consistência interna (coeficientes alfa de Cronbach e ômega de McDonald). Os resultados relativos à validade de critério apoiam parcialmente as evidências empíricas anteriores que consideram a satisfação e frustração das necessidades independentes em relação ao bem-estar e mal-estar, reforçando a necessidade de mais investigações. A versão brasileira da Need Satisfaction and Frustration Scale mostra-se um instrumento com qualidades psicométricas robustas para avaliar a percepção dos trabalhadores quanto à satisfação e frustração das necessidades básicas no contexto brasileiro de trabalho gig.

Este estudo amplia o escopo da pesquisa sobre necessidades psicológicas básicas ao introduzir um instrumento válido e confiável para avaliar as percepções de satisfação e frustração das necessidades dos trabalhadores no contexto brasileiro de gig work, uma população que tem sido negligenciada nas pesquisas da teoria da autodeterminação.

This study aims to explore the effect of different volumes of indoor greenery on perceived stress, stress, perceived productivity, productivity and perceived workplace satisfaction to support employees’ well-being.

In a cross-over experimental design, a homogeneous group of students was randomised in different orders where each participant experienced the same three conditions. Different volumes of indoor greenery were added to the experiment room (0%, 0.5% and 8%). With a Fitbit, sudoku and a questionnaire, the five variables were measured.

Findings show that perceived stress and heart rate (physical stress) are lower in the 8% condition. Productivity scores did not improve significantly, however perceived productivity did in the 8% condition. Positive trends could be seen for the variables in the 0.5% condition. Furthermore, 2/3 of the participants preferred the 8% condition, whereas the other 1/3 preferred the 0.5% condition. Overall, 1/3 of the participants mentioned that their optimal volume of greenery would be more than 0.5% but less than 8%. This research shows that the implementation of 8% indoor greenery contributes to a happier and more relaxing office place where employees get the feeling of being less stressed and more productive.

This research found that the largest volume of plants used (8%) has the most positive effect on the variables studied in this research. This study shows that participants’ heart rate, and therefore physical stress, became lower in the 8% condition. In this 8% condition, participants experienced less stress and perceived themselves to be more productive. Besides, 2/3 of the participants preferred being in the 8% condition, suggesting that after adding this volume of indoor greenery employees will be more satisfied with their workplace.

Where previous research discovered that indoor greenery has a positive effect on variables like (perceived) stress, (perceived) productivity and perceived workplace satisfaction, this research also provides support for the effect of different volumes of indoor greenery. Results obtained by the spatial coverage ratio approach can be easily applied to future research and practice.

Indoor greenery can contribute to making the office a happier and more relaxing place where employees get the feeling of being less stressed and more productive which in the long term might contribute to the overall well-being of employees.

To the best of the authors’ knowledge, this is the first study focusing on the effect of different volumes of indoor greenery on these five variables.

Students experience a range of benefits by participating in work-based learning (WBL) including increased employability skills, career development learning and enhanced industry networks. However, some approaches to WBL are not easily accessed by all students, with placement-based models placing demands on students to attend a physical worksite over a sustained period of time. This paper explores the emergence of non-placement WBL (NPWBL) as a global solution to broadening access to work-related activities. This approach is arguably a more sustainable model that enables students to engage in meaningful work-learning opportunities without the need for extended, physical proximity in a workplace.

Through a review of the literature, a typology of NPWBL is offered that organizes activities around the degree to which a student practices work and engages with an industry partner.

New and different NPWBL activities are continuing to emerge due to placement activities being described as resource intensive and in some cases unable to meet the demands of industry, specifically small and medium-sized enterprises (SMEs) and large student cohorts, international students and those with disabilities. The NPWBL typology presented here has been developed to meet these challenges, while ensuring the authenticity of WBL is maintained.

This paper highlights the need for rich discussions around the sustainability of WBL activities to ensure relationships between institutions and industry continue to thrive.

NPWBL is less-resource intensive and offers a sustainable option for universities without compromising on quality, meaningful experiences for students. The typology can be a useful prompt for educators to consider their objectives for student learning when embedding a NPWBL activity in curriculum.

The NPWBL typology is unique and valuable as it organizes NPWBL activities around the learning practices of the external partner (industry or community) and the learning practices of the student. This enables the typology to be transferrable across disciplines. The paper closes with reflective questions for educators when designing NPWBL activities.
