Razvoj metod strojnega učenja za identifikacijo kozmičnih delcev ekstremnih energij ter njihova implementacija pri iskanju fotonov ekstremnih energij s površinskimi detektorji Observatorija Pierre Auger

Despite their discovery already more than a century ago, Cosmic Rays (CRs) still did not divulge all their properties yet. Theories about the origin of ultra-high energy (UHE, > 10^18 eV) CRs predict accompanying primary photons. The existence of UHE photons can be investigated with the world’s largest ground-based experiment for detection of CR-induced extensive air showers (EAS), the Pierre Auger Observatory, which offers an unprecedented exposure to rare UHE cosmic particles. The discovery of photons in the UHE regime would open a new observational window to the Universe, improve our understanding of the origin of CRs, and potentially uncloak new physics beyond the standard model. The novelty of the presented work is the development of a "real-time" photon candidate event stream to a global network of observatories, the Astrophysical Multimessenger Observatory Network (AMON). The stream classifies CR events observed by the Auger surface detector (SD) array as regards their probability to be photon nominees, by feeding to advanced machine learning (ML) methods observational air shower parameters of individual CR events combined in a multivariate analysis (MVA). The described straightforward classification procedure further increases the Pierre Auger Observatory’s endeavour to contribute to the global effort of multi-messenger (MM) studies of the highest energy astrophysical phenomena, by supplying AMON partner observatories the possibility to follow-up detected UHE events, live or in their archival data

Tell me who you think you are and I tell you how you travel : Exploring the viability of market segmentation by means of travelers\u27 stated personality: Insights from a mature market (Switzerland)

People travel to different destinations for different reasons. In this study, we investigate the viability of market segmentation by personal traits (based on and exemplified by Jungian\u27s MBTI variables) of travelers from Switzerland, by performing a data-driven a posteriori segmentation by means of k-means clustering. To identify the segmentation power of personal traits, this analysis is complemented with a multiple discriminant analysis as well as a number of contingency tests to identify differences between the segments. We identified four clearly definable segments, which differ in terms of the psychographic traits of the segment members but also in terms of some sociodemographic characteristics as well as travel profiles. Despite a growing body of work on classical market segmentation, there is a growing but still limited number of works on potentialities of psychographic approaches relating to a traveler\u27s traits and/or peronality as a segmentation basis in tourism

A power perspective on knowledge transfer in internal succession of small family businesses

The aim of this paper is to apply a power perspective to knowledge transfer in internal succession processes of small family businesses. We argue that knowledge is a source of power. Distilling existing literature on small family businesses, knowledge transfer and power theory, we focus on the role of owner-manager and successor in internal succession. Propositions are formulated, theorizing the influence of (1) expert power, (2) decision-making power, (3) trust, (4) rivalry, and (5) capabilities. First, we conclude, familiness and high levels of trust in small family businesses influence power relationships between successor and predecessor positively. Second, the existence of high power imbalances within familiness can slow progress in knowledge transfer in succession, and particularly negatively impact on tacit knowledge transfer from one generation to the next

A systematic review of quality of student experience in higher education

Purpose: The purpose of this paper is to identify and synthesize major streams of research on quality of student experience in higher education, in order to present an agenda for future research. Design/methodology/approach: A systematic review of high quality journals published during the period 2000 to 2014 in the areas of quality of student experience and higher education was performed. Findings: Findings highlight current research trends on the quality of student experience in higher education. Results show five prevailing research streams: 1) exploration of learning experience; 2) exploration of student experience; 3) gender differences in assessment of higher education experience; 4) improvement in quality of student experience, 5) student satisfaction with higher education experience. Research limitations/implications: The identification of the five research streams presented in the findings of this paper provide the basis for a synthesis of key issues identified within each research stream. These discussions, along with the identification of the purposes and limitations of existential research allow existential issues concerning research on quality of student experience in higher education to be addressed. Practical implications: Literature currently portrays the quality of student experience as a student-centric idea. Together with the purposes and limitations identified in existing research, the paper proposes an agenda for future research that increases the variety of research streams that is essential to provide a deeper understanding of the student experience to enhance the delivery of quality in higher education. Originality/value: The findings contribute to the research scene by providing important insights in terms of the current trends and focus of existing research in the area of quality of student experience in higher education

Qualitative interpretive mobile ethnography

A growing number of studies use mobile ethnography and mobile devices to collect data, yet studies reveal a lack of coherent definition and inconsistencies in validity criteria. We draw on relevant literature from tourism, health and retail, and connect research designs utilizing mobile ethnographic methods. We show how these existing studies capture mobilities and social phenomena in boundaryless dynamic settings, allowing researchers to co-create knowledge with their participants. As a result, we offer a framework for mobile ethnography, consisting of four explanatory dimensions: the role of the researcher; focus of research; data collection and tools; and data analysis. Our methodological contribution specifies validity criteria and derives concrete implications for research practices in qualitative interpretive mobile ethnography

Antecedents of labor shortage in the rural hospitality industry: a comparative study of employees and employers

Although the role of human capital in the hospitality sector is critical, the industry faces challenges in attracting workers with a poor industry image frequently mentioned regarding labor shortages. This research paper attempts to investigate the factors influencing labor shortages by presenting the perspectives of employees and employers.Design/methodology/approachPrecisely 232 rural hospitality industry employees (n = 128) and employers (n = 104) in Northern Italy were surveyed using a written close-ended online survey and a quantitative research design as part of a convenience sampling approach. For hypotheses testing, Spearman's rho was used.FindingsA relationship between the shortage of professional workers and a variety of factors was found, including professional, digital, social and green skills, industry-intrinsic characteristics and symbolic image attributes of the industry. The findings show that some factors are more important for employees, while others are more significant for employers.Practical implicationsThis study demonstrates several practical implications for the hospitality sector by addressing the under-researched stakeholder group of existing hospitality employees, e.g. improving working conditions, reduction of manual operations through digital technologies, realistic career planning, employer branding, identification of skill deficiencies and provision of specialized trainings.Originality/valueMost research on labor shortages in the hospitality industry has focused on the perspective of either employees or employers. This study compares both perspectives, including the industry image, to gain a realistic picture of the relevant factors for a rural tourism destination in Northern Italy

Innovation capability and culture: How time-orientation shapes owner-managers' perceptions

This study offers a cross-cultural perspective to better understand how time orientation shapes tourism small and medium enterprises' (SMEs) innovation capability. We synthesise the extant literature and determine SME owner - managers' internal and external innovation capability. Distinguishing between short- and long-term cultures and comparing data from Australian and German, Austrian and Swiss (DACH country cluster) SMEs, results confirm that perceptions of innovation capability vary across cultures. Results for SMEs in short term-oriented cultures show stronger appreciation for consumer orientation, creating prospective profit and staff incentives; by contrast, SMEs in long term-oriented cultures place higher value on accessible knowledge, commitment to learning, and adaptation. To effectively manage innovation capability in SMEs, we suggest a balanced approach of considering both short- and long-term factors. Acknowledging the scarcity of SMEs' resources, we propose that owner-managers first focus on strengthening their internal organisational drivers of innovation to enhance their innovation capability. We also discuss implications for tourism policy, offer recommendations for the field of innovation research and note the study's limitations

Generation Y: evaluating services experiences through mobile ethnography

Purpose: This paper suggests mobile ethnography as a method for data collection, where Generation Y customers are integrated as active investigators. The paper aims to contribute to the debate on museums as experience-centred places, to understanding how the experience is perceived by Generation Y, to identifying the customer journey, to providing an insight into service experience consumption and to deriving managerial implication for the museum industry of how to approach Generation Y. Design/methodology/approach: Mobile ethnography is applied to the National Museum of Australia in Canberra with a sample of Generation Y visitors as the future visitor market. Findings: The paper finds that there is a need to involve museum management in measuring museum experiences, especially with regard to the definition and improvement of the service-delivery processes. Service experience must be appropriately managed by museum operators by collecting, evaluating, storing and reusing relevant data on customer experience. Mobile ethnography and tools such as MyServiceFellow offer an important potential source of sustainable competitive advantage by improving customer experience, particularly for Gen Y. Research limitations/implications: The most significant limitation is the exploratory nature of the single case study derived from a small sample within only one museum. Originality/value: This is one of the few studies to have addressed mobile ethnography in a service context and examined the museum experience of Generation Y. The paper finds that there is a need to involve museum management in service design to improve the service-delivery process, especially with regard to the different mindsets of the Millennials
