, 2021, izvirni znanstveni članek
Opis: Background/Purpose: This paper explores how organisational values can help to understand the interlinks of hotel brands and their hotel rating. The study assumes that the importance of organisational values in the service sector represents one of the key components of both growth and development of an organisation.
Methods: Conceptual content analysis was used on the dataset of organisational values found on websites of the top 100 European hotel brands. Advanced network analytic procedures were applied to identify clustered dimensions of organisational values among various hotel brands.
Results: Results identified shared organisational values among hotel brands clustered into four predominant dimensions: entrepreneurial, stakeholders, moral, and tradition. The study confirmed wide content variability of organisational values within the hotel brand industry.
Conclusion: The cluster analysis identified clusters of the most important words from values statements, concluding that hotel brands highly value “entrepreneurial” and “ethical” clusters. The island analysis approach on hotel brands’ level also reveals that organisational values in this sector are determined by many factors, including the scale and market positioning. Our study provides theoretical and practical implications to hotel brand strategists in order to better understand their current and desired sector position.

Spolni stereotipi v učbenikih angleščine: primerjava dveh izdaj serije učbenikov messages : master's thesisVeronika Mešić
, 2022, magistrsko delo
Opis: The Master’s Thesis focuses on gender stereotypes in English language coursebooks with special emphasis on the comparison between two editions of the coursebook series Messages. The analysis of coursebook series consists of descriptive, qualitative, and quantitative analysis of gender stereotypes in the linguistic (text) and visual (photographs, illustrations) forms. The Master’s Thesis classifies gender stereotypes as those instances in which women and men are portrayed stereotypically e. g. in their profession, through physical appearance, assumed binary traits etc. The found stereotypes are represented descriptively and statistically. Both editions of the coursebook series Messages are compared in terms of gender stereotypes in them. The findings of the study show an increase in gender stereotypes in the visual imagery between the two editions, unequal male to female characters ratio, and underrepresentation of women in occupational roles and activities.

K-vertex: a novel model for the cardinality constraints enforcement in graph databases : doctoral dissertationMartina Šestak
, 2022, doktorska disertacija
Opis: The increasing number of network-shaped domains calls for the use of graph database technology, where there are continuous efforts to develop mechanisms to address domain challenges. Relationships as 'first-class citizens' in graph databases can play an important role in studying the structural and behavioural characteristics of the domain. In this dissertation, we focus on studying the cardinality constraints mechanism, which also exploits the edges of the underlying property graph. The results of our literature review indicate an obvious research gap when it comes to concepts and approaches for specifying and representing complex cardinality constraints for graph databases validated in practice.
To address this gap, we present a novel and comprehensive approach called the k-vertex cardinality constraints model for enforcing higher-order cardinality constraints rules on edges, which capture domain-related business rules of varying complexity. In our formal k-vertex cardinality constraint concept definition, we go beyond simple patterns formed between two nodes and employ more complex structures such as hypernodes, which consist of nodes connected by edges. We formally introduce the concept of k-vertex cardinality constraints and their properties as well as the property graph-based model used for their representation. Our k-vertex model includes the k-vertex cardinality constraint specification by following a pre-defined syntax followed by a visual representation through a property graph-based data model and a set of algorithms for the implementation of basic operations relevant for working with k-vertex cardinality constraints.
In the practical part of the dissertation, we evaluate the applicability of the k-vertex model on use cases by carrying two separate case studies where we present how the model can be implemented on fraud detection and data classification use cases. We build a set of relevant k-vertex cardinality constraints based on real data and explain how each step of our approach is to be done. The results obtained from the case studies prove that the k-vertex model is entirely suitable to represent complex business rules as cardinality constraints and can be used to enforce these cardinality constraints in real-world business scenarios. Next, we analyze the performance efficiency of our model on inserting new edges into graph databases with varying number of edges and outgoing node degree and compare it against the case when there is no cardinality constraints checking. The results of the statistical analysis confirm a stable performance of the k-vertex model on varying datasets when compared against a case with no cardinality constraints checking. The k-vertex model shows no significant performance effect on property graphs with varying complexity and it is able to serve as a cardinality constraints enforcement mechanism without large effects on the database performance.

CALIBRATION OF A NEW METHOD FOR CREATING IMPERFECTIONS ON SLENDER STRUCTURESSimon Hudales
, 2022, magistrsko delo
Opis: For the design of slender structures consisting of plates and tubes, such as supporting structures at cranes, buckling is beside stress and fatigue often the governing failure criteria. Stability analysis of such structures is usually performed using the GMNIA method according to DIN EN 1993. For this purpose, a suitable geometric equivalent imperfection must be applied to the structure. Buckling inherent shapes are determined for this purpose and scaled according to applicable safety concepts. Including imperfections in stability analysis can generally be relevant for the load-bearing behavior of a structure. Within this master thesis work, the influence of the initial geometric imperfection on stability behaviour is investigated.
This study examines the influence, that imperfections imposed on members subjected to tensile stress have on stability behaviour. Tensile members of structures are identified and initial geometric imperfection is imposed on them in addition to critical members, that are subjected to compression stress. It is shown, that including imperfections on tensile members in stability analysis, has only a minor influence on stability behaviour and stiffness of the structure, both reducing it just slightly.
Further on, investigation on boom model, that is supporting structure of the crawler crane, is made. Boom model consist of main chord members and diagonals connecting them. At the joint connection of boom and two diagonal members, one subjected to tension and one subjected to compression stress, appears area of high shear stresses. Influence of the direction, that imperfection is imposed on the diagonal member, and what is the influence on the stability behaviour and structural strength is presented in this work. Most severe case of the two chosen direction is pointed out and discussed.

The language of appraisal in selected TED talks : magistrsko deloSarah Vidmar
, 2021, magistrsko delo
Opis: This master’s thesis examines five selected TED Talks by using Martin and White’s Appraisal Theory (2005). TED Talks are a specific form of speech which has spread worldwide with live TED events and even videos online since the first organised TED event in 1984. The theoretical background of this master’s thesis covers mainly Martin and White’s Appraisal Theory (2005), although it does include the views of other researchers, including Mary Macken-Horarik and Anne Isaac, as well as Geoff Thompson, on appraisal analysis as well. Furthermore, it encompasses a short overview of discourse analysis and systemic functional linguistics, as this is the theoretical framework from which Appraisal Theory has evolved. The empirical part includes the analysis of appraisal in the five selected TED Talks, chosen based on the assigned tag on the official TED web page. The selected TED Talks are: “Why I'm Done Trying to Be ‘Man Enough’” by Justin Baldoni; “Dare to Refuse the Origin Myths That Claim Who You Are” by Chetan Bhatt; “How Changing Your Story Can Change Your Life” by Lori Gottlieb; “My Year of Saying Yes to Everything” by Shonda Rhimes; and “Your Brain Hallucinates Your Conscious Reality” by Anil Seth.
The appraisal model explores the speaker/writer’s evaluation of certain occurrences, concepts and people in a form of his/her emotional responses, judgement and appreciation. Furthermore, it studies the speaker/writer’s positioning to alternative viewpoints and alignment with the text’s point of view. The aim of this thesis is to observe the use of appraisals in a contemporary form of a public speech, i.e. TED Talks. The further objective of this thesis is also to detect typical patterns in appraisal use within the genre of public speaking, specifically, within TED Talks which are known to have a set form and common features that distinguish them from other forms of speeches or academic lectures. Thus, this thesis aims to research ways in which the speakers of the selected TED Talks express themselves with the use of appraisals. Since all but one of the chosen five TED Talks are tagged as ‘Personal Growth’ on the official TED web page, the purpose of the research is also to see whether there are any differences in appraisal use, more specifically in the use of affect between the TED Talks tagged as ‘Personal Growth’ and the one which is not tagged as such and may therefore be more objective in its nature. Besides exploring attitudinal resources, the thesis also observes the occurrence of graduation resources and their prevalence, as well as the ways the speakers engage with their audience and their prevalence.
The appraisal analysis of the selected TED Talks has proved the use of all attitudinal resources in the delivery of these talks. Furthermore, the analysis has shown that the chosen topics of TED Talks have an influence on the speakers’ use of attitudes. Affect has a prominent role in most talks, however, the more the speaker tries to stay unbiased and objective, the more she or he avoids affect in relation to her-/himself and turns to appreciation. In addition, the speakers of the selected TED Talks tend to use graduation heavily in their narrative, force being the predominant graduation resource in all selected talks. Even though the analysis of engagement resources in the selected TED Talks showed the presence of dialogically expansive expressions to be more common in four out of five examined TED Talks, dialogically contractive expressions also occur frequently in the speakers’ narratives, revealing the speakers’ attempt to balance welcoming of alternative viewpoints and at the same time maintain self-assurance in their knowledge and beliefs by restricting other voices.

Euphemisms in the TV Series Grey’s Anatomy and House M.D.: Analysis of Selected EpisodesŽiva Rizmal
, 2021, magistrsko delo
Opis: The master’s thesis examines euphemisms in broadcast media: two American medical TV series – Grey’s Anatomy and House M.D. The main purpose of this thesis was to examine the use of euphemistic vocabulary in TV dialogue. By examining euphemistic words and phrases in selected episodes, we sought to provide insight into current euphemism use. Euphemistic references used in the TV series reflect social attitudes towards the concepts hidden behind euphemisms. We have identified 92 different euphemisms, which appeared 182 times altogether. The relatively frequent use of euphemisms in the TV series corpus may be attributed to the sensitive or taboo topics discussed (e.g., death, bodily functions, body parts, diseases, and sex). The analysis showed that most euphemisms found in the TV series corpus are sex related. Moreover, there are not many examples where euphemisms are used as a form of doublespeak or political correctness. The results suggest that TV scriptwriters employ euphemisms in their scripts for various reasons at both levels – that of the characters and that of the viewers. The analysed euphemisms most commonly fulfil the protective function at both levels, which means they are used to shield the listener from unpleasant words and avoid offense. A wide variety of euphemism formation types is used in the selected episodes of Grey’s Anatomy and House M.D. – most notably implication, metaphor, and particularisation. Furthermore, we analysed gender differences in the frequency of euphemism use in the TV series. The results showed that in the TV series corpus, male characters employ more euphemisms than female characters.

Building a Brand: A Multimodal Analysis of the Brand I Feel SloveniaEma Ivanuša
, 2021, magistrsko delo
Opis: This master’s thesis aims to analyse how the brand I Feel Slovenia uses verbal and visual texts to present its brand identity to the audience on its official website. Specifically, it aims to investigate how this brand uses multimodal texts to convey its core values (“Slovenian green”, “pleasant excitement” and “the elemental”); how it builds a relationship with its audience; and how verbal and visual texts contribute to the overall meaning-making in the presentation of the brand. The study uses multimodal discourse analysis to analyse five multimodal texts, which consist of verbal texts and visual texts, taken from the official website of the brand I Feel Slovenia. Both verbal and visual texts were analysed in terms of register variables (field, tenor and mode) and their intermodal connections. The analysis has shown that both verbal and visual texts convey the core values of the brand differently but are equally important in their presentation. Both types of texts build a positive relationship with the audience through the use friendly-neutral language, positive aesthetic appreciation of nature and bright, saturated colours. Both verbal and visual texts are important in the meaning-making in the presentation of the brand, although the latter draw more attention to themselves due to their size and are thus the dominant components.

Shakespeare’s Lady Macbeth and Leskov’s Sergei from Lady Macbeth of Mtsensk: A Stylistic Comparison of Two AccomplicesNina Gracej
, 2020, magistrsko delo
Opis: This Master’s Thesis is based on a stylistic analysis and comparison of Shakespeare’s Macbeth and Nikolai Semyonovich Leskov’s Lady Macbeth of Mtsensk, in particular the two accomplices and their direct speech. Shakespeare's Macbeth is a well-known tragedy with five homicides committed in fight for the throne. Leskov's Lady Macbeth of Mtsensk is a lesser-known Russian novel, in which an oppressed wife Katerina and her lover commit a series of crimes to achieve their goals. These works feature four protagonists: Macbeth and Katerina, and their partners and accomplices Lady Macbeth and Sergei. Because of the latter two, the plots lead the heroes to their bitter ends. Even though these works do not seem to have much in common, further analysis shows various parallels and shared elements. Shakespeare’s Macbeth is a dramatic tragedy, while Lady Macbeth of Mtsensk is a novel. Even though Aristotle (1959, 8) claims that tragedy is intrinsically connected with the dramatic genre, we were able to determine that this novel contains numerous elements of tragedy and can be analyzed as a tragedy. Furthermore, we discovered many parallels between the two: both follow the life of the protagonist, who each have one accomplice (i.e., Lady Macbeth and Sergei). They all desire a better life, and in order to achieve their dreams, they are willing to commit crimes. They all make fatal mistakes and are doomed to fail. In both texts, four murders take place. Our goal was to determine if the crucial murders are more thoroughly presented than the others. Then we analyzed the direct speech (figures of speech) of Sergei and Lady Macbeth in some crucial moments: when manipulating their loved ones and towards the end, when desperation and aggression strike out. When manipulating their partners, they mostly use echphonesis, repetition, antonomasia, sarcasm and antithesis. Towards the end, they become aggressive and anxious. They mostly use erotemas, ecphonesis, antonomasia, irony and sarcasm.
