Abstract
The “thermodynamic model” constitutes a unified theoretical framework for the coupled simulation of carrier and energy flow in semiconductor devices under general ambient conditions such as, e.g., the presence of a quasi‐static magnetic field or the interaction with an electromagnetic radiation field (light). The current relations governing particle and heat transport are derived from the principles of irreversible phenomenological thermodynamics; the driving forces include drift, diffusion, thermal diffusion, and deflection by the Lorentz force. All transport coefficients may be interpreted in terms of well‐known thermodynamic effects and, hence, can be obtained from theoretical calculations as well as directly from experimental data. The thermodynamic model allows the consistent treatment of a wide variety of physical phenomena which are relevant for both the operation of electronic devices (e.g., lattice heating, hot carrier and low temperature effects) and the function of microsensors and actuators (e.g., thermoelectricity, galvanomagnetism and thermomagnetism).

Abstract
Human resources can differentiate firms from their competitors or directly affect the success or failure of firms. As in many sectors, there is a need for qualified employees in the logistics sector, which is of great importance for the national economies. Qualified employees in this sector contribute to the success of the companies and the development of the industry. In this study, it is aimed to reveal the qualifications and characteristics of the labour force needed by logistics companies. It was also aimed to show the impact of COVID-19 on logistics job ads. For this purpose, a total of 1,410 job vacancy postings (before COVID-19) and a total of 1,700 job vacancy postings (during COVID-19) were searched on the kariyer.net website with the word “logistics” and analysed by content analysis method. As a result, it was found that the most advertised province was Istanbul in both periods, the most looked up experience requirement in the candidates was 1-5 years in both periods, the opportunities provided to the candidates (transportation, food and beverage, career, social activity) were not mentioned much in both periods. This study reveals the status of logistics job postings in the period before COVID-19 and during COVID-19. It was also aimed to show the impact of COVID-19 on logistics job ads. We investigated whether the logistics employee demand has changed and whether the pandemic is affecting workforce characteristics. This is the first empirical analysis of the impact of COVID-19 on logistics vacancy postings.

Abstract
Die Kurtaxe ist ein junges Kind des Kurortes Montreux, der heute die Vollendung des ersten Jahrhunderts seines Bestehens feiert. Während an verschiedenen schweizerischen Kurorten Kurtaxen schon verhältnismässig früh, im 19. Jahrhundert, auftauchten, zum Beispiel 1881 in Baden, 1868 in Bad Ragaz und 1874 in Davos, wurde eine entsprechende Abgabe in Montreux erstmals am 1. Juli 1941 aus der Taufe gehoben durch Inkraftsetzung eines «Règlement relatif à la perception d'une taxe officielle de séjour».

Abstract
Purpose
The purpose of this study is to investigate the financial well-being and social capital of Indian retirees. The paper investigates the extent of subjective financial well-being, the dependence on debts and the extent of bridging and bonding social capital of retirees with similar retirement pensions to understand the main issues they face.
Design/methodology/approach
Semi-structured interviews were conducted with 32 retired government schoolteachers. Two individuals transcribed the interviews after a pilot study, which helped remove repetitive responses. After ensuring the authenticity of the transcripts, the data was analyzed using interpretive phenomenological analysis.
Findings
The study's key findings reveal that retirees, armed with a clear understanding of their retirement income, exhibit a sense of financial control. At the same time, the presence of debt and the potential for high healthcare expenses adversely impact their subjective financial well-being. In terms of social capital, retirees predominantly rely on support from close-knit communities of friends and neighbors, as against their children. Additionally, retirees who migrate from their native places encounter challenges in establishing bridging social capital.
Originality/value
This study contributes to the ongoing discourse on financial well-being, specifically within the context of vulnerable groups such as retirees in India, where the absence of a state-supported retirement system adds a distinctive dimension. Against the backdrop of India's traditional societal framework, the research extends the existing literature by delving into the nuanced effects of evolving social dynamics on the social capital of retirees.

Abstract
Purpose
The increase in the supply chain complexity demands new professionals who are able to deal with the new challenges faced nowadays. The purpose of this work is to propose an international university–industry collaboration model to develop supply chain management competences in students as a tool for the training of future professionals.
Design/methodology/approach
This study proposes an international collaboration model to develop supply chain competences. The model consists of three main phases from the genesis of the collaboration to the assessment of the competence development. This study validates the model collaborating with one of the largest retailer companies in Mexico.
Findings
Results identify collaboration good practices and point at possible improvements for the next model iteration. This study identifies four key supply chain competences as part of this model. Three didactic approaches (i.e. guidance methods) and two student’s involvement schemes were tested. The results show that professors acting as an advisor (i.e. acting as a guider without telling student directly what to do or how to do it) plus a voluntary student’s involvement in the project promote better competence development.
Originality/value
The first contribution of this research is the definition of an international collaboration model that promotes competence-based education. Also, this study documents good practices for this type of partnership. The second one refers to a large-scale model validation (i.e. 14-week experiment in nine different regions of Mexico involving a retail company, 20 professor-researchers and more than 100 students). The third contribution includes the assessment of different levels of competences development using diverse students’ participation schemes and professor’s guidance methods.

Abstract
Purpose
This paper aims to identify the occupational profiles of a logistics and a supply chain (SC) controller, both promising SC professions, examining the required competences and tasks undertaken while taking into account current trends in supply chain management and its wider dimensions.
Design/methodology/approach
The study used a content analysis based on job advertisements for the position of logistics controller and SC controller. The collected material allowed the construction of an occupational competence mix model in the style of Cheetham and Chivers for the logistics and SC controller, and the identification of the level of competence of both professions, using the model proposed by Czapla. In addition, the analysis of the data was supplemented by use of the Anova test and a radar chart.
Findings
The SC and logistics controllers have a high degree of similarity in both the meta and core competences areas. Similarities also occur in the case of the analysed groups of tasks undertaken by these professions. Tasks in the areas of “definition” and “maintaining” prevail. The SC controller and the logistics controller are considered “engaged inspirers” because they have reached this level of professional competence. Both these professions can ensure an effective, sustainable and transparent SC through direct cooperation with the SC manager and/or logistics manager.
Research limitations/implications
This study uses a content analysis based on job advertisements addressed to the German market. These job advertisements are standardized, and therefore, provide only a general outline of the competences and tasks of the SC and logistics controllers.
Practical implications
The study provides information to practitioners by identifying the competences and tasks assigned to the SC and logistics controllers that are needed to improve the efficiency and transparency of the SC and its management. The research is an incentive for people involved in education to adapt changes in curricula in the business (accounting, controlling and logistics) and engineering (related to logistics) fields of study by creating courses based on SC controlling or/and logistics controlling.
Originality/value
The study shows the current, necessary changes for SC professionals (e.g. the appointment of a SC controller and/or logistics controller) resulting from changes in business and the challenges for SC management (e.g. transparency and sustainability).

Abstract
Purpose
The new era of supply chain management is characterised by key change drivers, e.g. Industry 4.0, and post-COVID-19 VUCA (volatility, uncertainty, complexity and ambiguity) business environment, in addition to the rising requirements for sustainability, responsiveness and customer centrism. An important and topical question in this context is what supply chain managerial competence logistics managers need to possess in order to enhance their individual performance in the new era. This question is addressed in this paper, which also explores the nexus of supply chain managerial competence expectation and possession upon which human resource development strategies are proposed accordingly.
Design/methodology/approach
The survey research design is adopted to empirically examine logistics managers’ supply chain managerial competence in the new era, and the forward-backward translation process was strictly followed. Data were collected through a survey conducted with owners or managers of Vietnamese firms whose business is in the logistics and related business areas, and 269 valid responses were used for analysis.
Findings
Results indicated that the proposed profile of four groups (foundation, core, specialist and technology-IT) and 38 competencies are valid and important to the individual performance of logistics managers in the context of Vietnam, which supports the tenet that logistics managers in the new era need to have a well-rounded profile of competencies, including those derived from contemporary change drivers. It was also found that the foundation competency group is perceived as more important than others, which is context specific given the current logistics development in Vietnam. Besides, it was also revealed that respondents in this research currently possess those competencies at a level which is lower than their perceived importance. An Importance-Possession (IPM) Matrix of Competency Development was mapped accordingly.
Research limitations/implications
The generalisation of this study would require further empirical examination from similar studies in other contexts, i.e. in other manufacturing and service sectors as well as in other developing and developed countries where logistics development is at different stages.
Practical implications
This research provides insights into the current competency profile of logistics managers in Vietnam, which can assist senior management with human resources development in their firms. Specifically, it is essential that Vietnamese logistics firms focus on providing education and training opportunities, both internally and externally, to enhance the level of possession of all competencies whose gaps between perceived importance and possession are the largest across the groups, especially those in the Maintaining Sustainably and Growing quadrants of the IPM.
Originality/value
Firstly, this research introduces an improvised framework of logistics managers’ supply chain managerial competence adopting the contingency approach, contributing to expanding the body of knowledge on how the competency profile of logistics managers should be developed. Secondly, the IPM matrix of competencies introduced in this research can be used as both the conceptual and managerial tool to classify and prioritise competencies for various purposes, e.g. education, training and policy implementation based on the nexus of supply chain competence expectation and possession.

Abstract
Purpose
Due to the recent disruptions caused by COVID-19, global supply chains are stress tested. The affected supply chains have interfered with market tonnage prices for the yield of perishable products like mangoes that are highly dependent on their quality. This research, through empirical findings, thus determines and comprehends the factors influencing mango quality (size).
Design/methodology/approach
A framework is developed for finding the potential factors of quality building on the previous literature and studies on the available topic. The data collection included face-to-face interviews comprising 240 farmers, hired managers and preharvest contractors in India's Jangaon, Rangareddy and Yadadri Bhuvanagiri districts of Telangana state. The data analysis is done using multiple regression, and the outcomes form the basis of the design of the experiments model.
Findings
The empirical insights support that the quality of mango is affected by factors such as the number of picking cycles, the cost of fertilizer, the variety of fertilizers used, the variety of pesticides used and pesticide application frequency. The direct implications are the benefit to farmers in improving mango quality and maximizing profit per yield cycle.
Research limitations/implications
To the best of the authors’ knowledge, the first research that has specifically focused on holistically improving the quality(size) of mangoes.
Originality/value
The findings contribute to the perishable supply chain literature, specifically to the mango study, to comprehensively showcase the factors impacting the quality of mangoes and provide guidance to farmers regarding orchard practices.
