A framework for managing future supply chain trends: utilization of lean, agile and leagile strategies
Waleed Rashad, 2020, doktorska disertacija

Opis: The supply chain has become very essential to run any business nowadays. Throughout the history of business, the professionals have been trying always to find out the best practice, and as long as the business concept is evolved over time, the practice, methodologies and techniques of doing the business also have been evolved. This evolvement led to the concept of supply chain initially and then later it became essential to have strategy for supply chain. The evolvement of the markets, globalization, and new technologies became very decisive subjects for building any supply chain and developing its strategy, but there are many other events that may take place which could enforce the supply chain decision makers to change the current approach of running their business. The dynamic business environment and the possible future trends of the global markets represent a real challenge for development of appropriate supply chain strategies, like lean, agility, and leagility. Therefore, it is very important to assess how different possible strategies are suitable for the future changes of the markets? This is to enable the supply chain to be prepared with adequate strategies for different future scenarios. To achieve this aim of preparing the supply chains for the future with adequate strategies, a deep study is done to research lean, agility and leagility, explaining the similarities and differences of these concepts. These strategies are dealing with the most important factors in supply chains; the time and the cost, what is the key reason for selecting these particular strategies lies in the fact, that they are concerned with improving the effectiveness and responsiveness in the supply chain and this is extremely important for the future. We continued study of these strategies by development of three possible future scenarios for energy scarcity, new international monetary system, and wars. The reason of developing these particular scenarios is because they are concerned with the most important political and economic events which could happen and affect the supply chains in the future (EY, 2013; Cook, 2006; Sokov, 2015). These scenarios are established to anticipate the possible challenges which could face the supply chain strategies in the future and to evaluate the suitability of supply chain strategies for such future scenarios. A survey of 150 supply chain professionals, who are working currently in the field of supply chain management, is done in two phases. The first phase is focusing on recognition of the opinions of surveyed supply chain professionals towards the supply chain strategies and their utilization. Based on the theoretical knowledge of the academic literature reviewed in this research, proposed scenarios, and the feedback of professionals in the survey, it was evident that supply chains’ managers need adequate framework, which will support improvement of current and future supply chain management. Therefore, the grounded theory methodology is used to create a new conceptual framework. The core idea of the proposed framework is to improve the global sourcing practice, which consequently will enable improving the management of supply chains according to the predicted scenarios. A second phase of survey is conducted to present the proposed framework to the supply chain professionals for evaluation. The proposed framework adds value to the global sourcing process, which enhancing the supply chain collaboration and helps to support the selected supply chain strategies for consideration – i.e., lean, agility, and leagility, to work better in the future. The proposed framework represents scientific contribution to the supply chain strategies utilization in practice. The results of this contribution are obviously to fill the gap highlighted by the supply chain professionals in the survey, who highlighted the essential need for improvement to the supply chain collaboration globally, and this will be the basic c

Self-protective behaviour among young adults during public health crisis
Luka Jelovčan, Kaja Prislan, Anže Mihelič, 2020, izvirni znanstveni članek

Opis: Purpose: The purpose of this article is to examine perceptions of factors deriving from the theory of planned behaviour among younger adults in times of public health crisis, their self-protective behaviour compared to other age groups, and test the predictive factors according to the theory of planned behaviour. Design/Methods/Approach: An online survey has been conducted to examine self-protective behaviour in times of public health crisis. The survey was distributed to Slovenian citizens (n = 280) using the social network Facebook. Descriptive statistics were used to describe the sample and measured variables. Multiple regression analysis was conducted to determine associations between identified factors. Findings: The results of the study indicate that there are no significant differences in self-reported self-protection between younger adults and others. Additionally, attitude toward self-protective measures is the most important predictor of self-protective behaviour for both age groups. Only the attitude is significantly associated with self-protective behaviour among young adults, whereas among others, all three predictors are significantly associated with self-protective behaviour, explaining nearly twice the variance. Research Limitations/Implications: This research contributes to the understanding of motivators that drive individuals to engage in self-protective behaviour in times of health crises. It provides insight into young adults' self-protective behaviour. Most of the limitations are related to the sample, which only contains respondents from one social network and one country. Originality/Value: To the best of our knowledge, this is the first study that explored the self-protective behaviour of young adults during COVID-19 using the theory of planned behaviour and compares the differences in self-protective behaviour predictors among different age groups.

Global sourcing strategies
Waleed Rashad, Zlatko Nedelko, 2020, izvirni znanstveni članek

Opis: The main purpose of this paper is to develop a framework for utilization of lean, agile, and leagile strategies in the supply chains, where the core idea of the framework is to improve the global sourcing practices. Based on in-depth interviews with supply chain professionals and grounded theory approach, we constructed a framework of global sourcing improvement to support better utilization of lean, agile, and leagile strategies, which we believe can help the supply chains worldwide to act better, especially in various difficult conditions and sustain their business accordingly. Our proposed framework also contributes to the UN´s Sustainable Development Goals, since the core concept of the framework is to establish a new organization under the umbrella of the UN to improve the global sourcing and consequently the usage of supply chain strategies accordingly. The applicative part of the paper reveals characteristics of new developed framework, ranging from its purpose and aims, structure, key processes, functions, and its financing. Along with validation of the framework are presented benefits for society, industry, and global economy. Additionally, the paper also reviews the impact of the current health and economic crisis caused by COVID 19, on usage of the three supply chain strategies namely; lean, agility, and leagility to see how they can work in the difficult time, as COVID 19.

Language of Appraisal in Book Reviews: A Case Study
Katja Časar, 2020, magistrsko delo

Opis: This master’s thesis presents an analysis of appraisal in the case of ten book reviews. Their selection is based on several criteria that make them representative of this text type. The selected texts evaluate novels, novellas and short stories that were ranked top 300 according to the Open Syllabus Project 2.0 online data base. This means that they fall into the category of the most often assigned books in educational institutions. The authors of the selected texts are editors, journalists and writers, and there is an even number of male and female reviewers. The purpose of the study is the appraisal analysis of the contemporary English language; therefore, only the recently published texts were selected. The main methodology used in this master’s thesis is the appraisal theory developed by James Martin and Peter White (Martin and White). This theory evolved in the systemic functional linguistics, and it relies on the theoretical concepts of Michael Halliday (Halliday). The appraisal analysis was conducted with help of the analytical tool Catma 5.0, which enables annotation of texts, their analysis and the visualization of data. The results of the research show that the most frequently used attitudinal resources are the expressions of appreciation. Therefore, the evaluation of the story and everything associated with it is in the foreground of the book reviews. The analysis of the selected texts reveals that evaluation is mostly explicit, meaning that the reader is directly invited to engage with the book. The findings indicate that the attitudinal resources are graded more according to intensity and quantity and less according to prototypicality and marginality. This conclusion draws attention to the variety of lexical and grammatical structures in the selected texts that are assumed to be characteristic of this text type in general. The results also show that the reviewers do not include many external sources into the text, which consequently narrows down the dialogistic space and excludes alternative views and attitudes. The appraisal analysis points toward the text-structural and semantic characteristics of book reviews in general. The structure of the selected texts consists of the following elements: information about the author and the book, the plot summary and evaluation of these elements, which are often intertwined. Some reviews also include personal accounts, book details and/or numeric ratings. The most significant semantic characteristic of evaluation expressed in the selected book reviews is the critique of the Western oppressor. The reviewers judge crimes against humanity and question Western perspectives. They also imply the complicity of the readers because they are viewed as members of the Western identity. Additionally, the results of the analysis show that the book reviews are contextual and intertextual text types, which include various means for the realization of appraisal. A vast spectrum of lexical and grammatical structures makes book reviews an interesting research topic with many possibilities for further research.

Technological valley of death as an emergent evolutionary phenomenon
Petra Fic, 2019, magistrsko delo

Opis: Perceptual researchers often argue that natural selection supports veridical perceptions, respectively those that accurately reflect the environment. They also claim that beings whose perceptions are truer are also more fit. This assumption was tested using standard tools of evolutionary game theory in a simple environment. The result was that more veridical perceptions are not necessarily more successful. In the majority of the parameter space, veridical perceptions are extinct in competition with simplified perceptions, based on adaptive behavior in a given environment. In the thesis, we build upon mentioned territorial games introduced by Mark, Marion, and Hoffman in 2010, and extend four of their territory perception and selection strategies with two novel ones that together constitute a model of technological readiness valley of death. Whenever utility of a resource is not monotonous in the amount of that resource, the technological valley of death emerges. While the development of the science behind these models is in its infancy, modeling and understanding the phenomenon may shed light on progress and related phenomena in society.

Design of geometry and numerical simulation of the operating characteristic of the rotor of the wind turbine
aljaž Janič, 2018, diplomsko delo

Opis: The diploma thesis consists of design and numerical simulation of the wind turbine. Geometries are designed according to two theories, the Betz theory and the Schmitz theory. I used Solidworks for 3D modeling of the both rotors. Using Ansys software package, we performed numerical simulations of a rigid body for two different wind speed regimes. We were interested in the angular velocity of the spinning blades, which in combination with moment give us power.

Analytical method for the analysis of stone-columns according to the Rowe dilatancy theory
Boštjan Pulko, Bojan Majes, 2006, izvirni znanstveni članek

Opis: In this paper a new analytical method to analyse the behaviour of rigid foundations stabilized by end bearing stone-columns is proposed. The stone column and the surrounding soil are treated in axial symmetric conditions as a unit cell. The stone column is assumed to behave as an Mohr-Coulomb rigid-plastic material with non-associative flow rule according to the Rowe stress dilatancy theory and the soil as an elastic material. These common assumptions, combined with equilibrium and kinematic conditions, lead to the simple analytical closed-form solution for the prediction of the behaviour for rigid footings resting on stone-column reinforced ground. The parametric study is presented to show the effect of dilatancy of the granular material on the deformations and stresses in the ground and its beneficial effect on settlement reduction. The results of the new method are compared with some already known analytical methods and some published field test results and observations.
