Describes a spreadsheet approach for implementing Wagner‐Whitin (WW) and Silver‐Meal (SM) methods for lotsizing time‐varying demands. Suggests that this approach manages the computation and makes tedious and repetitive tasks more interesting; consequently, the student/user can concentrate on the concepts. Outlines the methods, which involve the computation of incremental costs (inventory carrying and replenishment costs) for several alternatives in each period. Presents a spreadsheet template to compute the incremental costs for possible alternatives which is created by using only a small number of spreadsheet formulae and a series of copy commands. The costs are displayed as a matrix. Describes a step‐by‐step procedure to determine the period and the quantity of replenishment.

Being an efficient mechanism for the value of money, public–private partnership (PPP) is one of the most prominent approaches for infrastructure construction. Hence, many controversies about the performance effectiveness of these delivery systems have been debated. This research aims to develop a novel performance management perspective by revealing the causal effect of key performance indicators (KPIs) on PPP infrastructures.

The literature review was used in this study to extract the PPPs KPIs. Experts’ judgment and interviews, as well as questionnaires, were designed to obtain data. Copula Bayesian network (CBN) has been selected to achieve the research purpose. CBN is one of the most potent tools in statistics for analyzing the causal relationship of different elements and considering their quantitive impact on each other. By utilizing this technique and using Python as one of the best programming languages, this research used machine learning methods, SHAP and XGBoost, to optimize the network.

The sensitivity analysis of the KPIs verified the causation importance in PPPs performance management. This study determined the causal structure of KPIs in PPP projects, assessed each indicator’s priority to performance, and found 7 of them as a critical cluster to optimize the network. These KPIs include innovation for financing, feasibility study, macro-environment impact, appropriate financing option, risk identification, allocation, sharing, and transfer, finance infrastructure, and compliance with the legal and regulatory framework.

Identifying the most scenic indicators helps the private sector to allocate the limited resources more rationally and concentrate on the most influential parts of the project. It also provides the KPIs’ critical cluster that should be controlled and monitored closely by PPP project managers. Additionally, the public sector can evaluate the performance of the private sector more accurately. Finally, this research provides a comprehensive causal insight into the PPPs’ performance management that can be used to develop management systems in future research.

For the first time, this research proposes a model to determine the causal structure of KPIs in PPPs and indicate the importance of this insight. The developed innovative model identifies the KPIs’ behavior and takes a non-linear approach based on CBN and machine learning methods while providing valuable information for construction and performance managers to allocate resources more efficiently.

This paper aims to develop a vision for the future identifying how digital nomadism affects the labor markets in the tourism industry.

The qualitative research method was used. The research data were collected using a semistructured interview form developed by the researcher. The sample consists of twenty people working in the tourism industry as tour guides, travel agency owners, accommodation sector employees and professional managers. The content analysis method was used to analyze the data.

It was found that employees in the tourism industry are familiar with digital nomadism, interact with employees working as digital nomads and may prefer the digital nomad way of working, while employees in the accommodation sector cannot work as digital nomads due to the nature of their work. It is shown that digital nomadism can be applied to tour guides and travel agency owners.

The data was collected from employees of the accommodation sector, travel agencies, tour guides and employees of the Turkish tourism labor market. It is recommended that the tourism labor markets adapt to the digitalized world and adjust their working models in this context.

This is one of the first studies on the impact of digital nomadism on the tourism labor markets.

The purpose of this paper is to look at the impact of the Government subvention to the University of Malawi (UNIMA) from 2004 to 2009 financial years on its libraries and assess levels of fund raising initiatives in the libraries.

The study adopted a case study approach. Interviews were conducted with five college librarians in the University of Malawi libraries. University budget estimates from 2004/2005 to 2009/2010 financial years were used to assess the amount of income generated by the libraries. Data are presented in the form of tables and analysed by calculating percentage increases and decreases.

UNIMA as a whole has done extremely well in generating income equivalent to subvention. On the other hand, UNIMA libraries are on the receiving end. From 2004/2005 to 2007/2008 financial years, no income was captured in the university budgets from the libraries. In the 2008/2009 and 2009/2010 financial years, UNIMA libraries realised 7.2 per cent and 5.4 per cent of the income. This means UNIMA libraries were heavily dependent on government subvention for their operations. Fundraising is not emphasised despite being an appropriate and alternative source of funding.

The study recommends that college librarians should consider diversifying income‐generating activities and consider fund raising activities as well. Heavy reliance on government subvention is not sustainable. Libraries should seriously consider fundraising.

There is an information gap on fund raising activities in UNIMA libraries. This information bridges the gap on sources of income for UNIMA libraries and provides an assessment of fund raising initiatives taken by UNIMA libraries.

The chapter is aimed at comprehensive discovery of the basic legal tools to improve the quality of corporate governance from the standpoint of efficient revealing, preventing and shooting negative implications of internal corporate disputes. The subject of the study, in particular, is regulatory and non-regulatory enactments in this area. Within the study we employ basic approaches that allow to reveal the conditions ensuring efficient corporate governance, i.e., dialectical, historical, systemic, formal-logic, and comparative-law ones. Therewith, the main focus is on the application of system theory developments in terms of the methodological techniques to describe any system object.

Regarding the disputes between participants of the corporation, we substantiate the need of creating conditions for the highest account of opinions of all the participants in the development of collective will, as well as for restraint of major participants from potential abuses (through accumulative voting mechanism, implementing “two keys” principle, etc.). Special attention is paid to the issues of procedure and content of interest-collision transactions made by economic societies.

The authors point out definite guidelines to improve legislation in anti-conflict aspect (forms of holding general meetings of participants, exclusive and non-exclusive competence of governing bodies, the content of acts coordinating interested-party transactions, etc.).

In this explorative study, the authors aim to contribute to the literature on socio-economic integration and migrant entrepreneurship by conducting an investigation into the migration journeys of Ukrainian migrants developing entrepreneurial activities in Krakow, Poland. The main research question for this study is as follows: how do migrant entrepreneurs establish their businesses in the new host country context? The authors have undertaken a qualitative comparative study, adopting an interpretivist paradigm involving 32 interviews with migrants of Ukrainian descent in Kraków and other cities, who are engaging in entrepreneurial activity. The findings reveal the critical importance of diaspora networks in business foundation and development, especially the linkages between the Ukrainians and other migrants from other former Soviet countries, a finding in line with Rodgers, Vershinina, Williams, and Theodorakopoulos’s (2019) findings from a study of migrants in the UK. The authors also demonstrate how as a result of the worsening economic and political climate in Ukraine, many businesses are being transferred to Poland.

In this paper, we analyse and provide an overview of the functions the state aid in Kosovo and demonstrate their compliance with EU rules in fidls of state aid Article 107(3)(b) TFEU. We deal with the level of implementation of state aid rules by Kosovo institutions, especially Kosovo’s Commission for State Aid. We provide an overview of the State of Kosovo in fulfilling its obligation on state aid issues based on the Stabilisation and Association Agreement and others documents, which is a step forward for EU integration. We do this by conducting a comparative analysis of the data collected from both primary and secondary sources to demonstrate the current situation on state aid in Kosovo and determine the most appropriate means to build a strong and efficient National State Aid Commission. Findings from the study show that Kosovo Aid Commission is still in a development phase, and more needs to be done to create an adequate state aid regime. We propose measures to ensure the effective implementation of the state aid law.

This study aims to investigate the perceptions of Iranian English teachers about their teaching efficiency through a specific practicum course, namely, language teaching methodology. Drawing on a marketing education perspective, the researchers sought to measure the service quality offered in universities by examining teachers’ satisfaction with the curriculum.

Using quantitative gap analysis, the study evaluated the knowledge and skills of teachers in their preservice education regarding the perceived importance of knowledge and skills required in practice. The study involved 120 English as a foreign language teachers holding a BA degree from two universities in Iran, each with two to four years of teaching experience in the private sector. Data were collected using a 40-item semantic differential Likert scale developed by the researchers. The scale incorporated two components that assessed teachers’ perceived importance of knowledge and skills and their preservice educational preparation.

The findings revealed that most participants were overprepared in various items. However, there were some gaps in content knowledge and skills. Reasons for these gaps mainly included having adequate experience of and/or familiarity with course content, having completed relevant courses beforehand and imitating role model teachers. Teachers’ underpreparation was attributed to their lack of preparation in some specific subjects due to limited skill, practice, motivation, experience and familiarity with that content area.

This study explores the perceived knowledge and skills of Iranian English teachers and provides empirical insights into higher education service quality and customer satisfaction.

Companies often conduct general Employee Opinion Surveys (EOSs) to measure some features or outcomes of an organization. Converting data to results is routine and governed by the design of the EOS and the use of standard statistical methods. However, as one moves away from results to their meanings or conclusions, and from conclusions to recommendations, other factors and variables come into play. These factors and variables are governed more by the context, the presence of constraints, the intuition of the decision makers, and the actions by engaged agents. Essentially EOSs produce ambiguous conclusions and recommendations because they are “knobless,” or lacking underlying processes which are controllable by management. The theory of the organizational hologram has evolved operationally into a family of Organizational Diagnostic Survey (ODS) forms which generate sets of results representing managerially controllable processes or combinations of processes. That is, the ODS provides a set of x‐axis variables that can be employed to explain variability in EOS results, which are viewed as dependent variables plotted on the y‐axis. Every item in an ODS form is “knobby.” The relationships among the questions and higher order results are causal and structured with known interdependencies. Combining ODS and EOS allows knobby analyses of knobless survey items.
