The stable hull of an exact ∞\infty-category

We construct a left adjoint $\mathcal{H}^\text{st}\colon \mathbf{Ex}_{\infty} \rightarrow \mathbf{St}_{\infty}$ to the inclusion $\mathbf{St}_{\infty} \hookrightarrow \mathbf{Ex}_{\infty}$ of the $\infty$-category of stable $\infty$-categories into the $\infty$-category of exact $\infty$-categories, which we call the stable hull. For every exact $\infty$-category $\mathcal{E}$, the unit functor $\mathcal{E} \rightarrow \mathcal{H}^\text{st}(\mathcal{E})$ is fully faithful and preserves and reflects exact sequences. This provides an $\infty$-categorical variant of the Gabriel-Quillen embedding for ordinary exact categories. If $\mathcal{E}$ is an ordinary exact category, the stable hull $\mathcal{H}^\text{st}(\mathcal{E})$ is equivalent to the bounded derived $\infty$-category of $\mathcal{E}$.Comment: 22 pages, accepted versio

Introducing Game Development into the University Curriculum

Integrating computer games development into computer science curriculum is gaining acceptance. However, the question is how this should be done. In our course on computer game development we present all necessary steps that a game project has to address, from design to publication and marketing, from the theoretical to the practical point of view. The goal is that each student makes a casual game for Apple iOS platform and possibly publishes it. The games are built on our xni framework for iOS, which is a subset of Microsoft’s xna. We take an iterative incremental approach to teaching game development, where we discuss a number of selected topics from various categories, such as gameplay design, graphics and artificial intelligence, each week. Thereafter the students receive mandatory and non-mandatory assignments that force them to add functionality to their game and, thus, steadily progress towards their goal. At the end of the course more than 20 % of all projects were ready for the Apple App Store, which, together with student pools saying that the course was one of the best executed courses they attended, confirms the viability of the suggested scheme

The Easement in Gross Revisited: Transferability and Divisibility Since 1945

Courts have disagreed about the nature, obligations, and privileges that accompany the easement in gross. Generally, an easement is an interest in land which gives the easement holder the right to use that land for a specific purpose, free from the will of the landowner. An easement is in gross when the benefit from the use of another\u27s land inures to the easement holder personally, rather than to the holder\u27s land. The land that is subject to the holder\u27s right of use is the servient tenement. Courts agree on these basic principles of an easement in gross, but have disagreed on the holder\u27s right to transfer his interest to a third party. Similarly, no uniformity exists among courts on the right of the holder of an easement in gross to divide and share his interest with a third party. In the mid-1940\u27s, two commentators compiled and analyzed the state of the law concerning the transferability and divisibility of easements in gross. Both writers attested to the importance of easements in gross in facilitating commercial activity, especially in the area of transportation rights of way and public utilities. Each author noted that the common law rule disfavored transferability and divisibility of easements in gross because the rights accompanying the easement were personal to the holder. The two writers noted, however, that the common law rule was beginning to changeand that courts were allowing limited transfers and divisions of easements in gross.\u27 Emphasizing that a party could not realize the maximum value of an easement in gross unless the courts allowed the easement holder to transfer or divide his interest, both men concluded their essays with a call for a greater consensus among the courts and for fewer restrictions on the transferability and divisibility of easements in gross. These commentaries appeared over forty years ago. Today,easements in gross continue to play an important commercial role and are finding new uses in fields such as environmental conservation and historic preservation.\u27 Despite the growing importance of easements in gross, commentators during this forty-year span have neglected to address the questions of transferability and divisibility. The purpose of this Note is to gather and analyze the law of transferability and divisibility of easements in gross as the law has developed since 1945. Part II of this Note differentiates easements in gross from other types of real servitudes. Part III discusses the variety of approaches that courts and legislatures have taken in addressing the question of transferability. Part IV deals with the development of the independent exercise doctrine of divisibility.Last, part V advocates that courts should place less emphasis on terminology and should direct more attention toward the parties\u27intentions and the surrounding circumstances of the easement interest when determining the transferability and divisibility of easements in gross

Early diagnosis of contrast mediainduced nephropathy in intensive care

At the Research Department in hospital of Nova Gorica we are faced with new cathlab practice and problems connected with it. Together with other project partners we intend to investigate contrast media induced nephropathy by measuring the release of NGAL, which is considered to be a good biomarker for detecting reduced kidney function. Our first priority is extensive study of NGAL and develop special detecting lab-on-a chip that should be small and simple to use at every day hospital practice. Our second priority is to develop new and intensify pre-existing collaborations and exchange of knowledge between project partners

The Effect of Demographic Characteristics on Self-Medication Patterns: A Cross-Sectional Nationwide Study from Slovenia

Self-medication is defined as the use of medicines without medical supervision to treat one’s own ailment. It is a part of a help-seeking behaviour that depends on socio-cultural and personal factors, which is why people react to the illness differently and also take different measures to cope with it. The aim of this study was to explore the Slovenian citizens’ attitudes towards self-medication. The study included a random sample of 1,000 Slovenian inhabitants, stratified to all Slovenian regions. This was a postal survey. Participants were mailed a self-administered questionnaire about attitudes towards self-treatment. In the statistical analysis we used independent t-test and c 2-test. We received 410 responses (41.0% response rate). In the past year, 389 (94.9%) respondents practiced self-medication. Most respondents (209, 52.1%) supported and used it in everyday life. The majority of the respondents (274, 77.2%) practiced self-medication when symptoms emerged. When symptoms lasted for one week or less, 210 (56.5%) of the respondents practising self-medication visited their doctor. The respondents agreed mostly with the statement that their doctor had a positive relationship towards self-medication. Younger people were more confident about the absolute safety of self-medication whereas older people were more certain that they could practice it no matter what disease they might have. As self-medication is very common among Slovenian population and various demographic factors affect the opinions about it and the reasons for its use and also a doctor-patients communication about it, it is important that doctors, especially those in primary health care settings always ask about its use. This is of a particular importance when dealing with older and retired patients, which are more likely to suffer from more chronic diseases and use alternative medicine, which is a common part of self-medication. Also, it is important to educate young people about possible unsafe practice of self-medication

HEALTH SEEKING BEHAVIOUR IN GENERAL POPULATION WITH PSYCHOLOGICAL SYMPTOMS

Background: Health seeking behaviour is a complex construct in patients with psychological symptoms. The aim of this study was to determine a one-month prevalence of psychological symptoms in Slovenian general population and to identify correlates of health seeking behaviour. Subjects and methods: This study was conducted in a representative sample of 1,002 randomly selected Slovenian citizens, stratified according to sex and age. We used a method of computer assisted telephone interview (CATI). The questionnaire consisted of demographic questions, questions about the prevalence and duration of preselected symptoms in the past month (irritability, nervousness), questions about the presence of chronic diseases, EQ-5D questionnaire and the questions on health seeking behaviour (self-treatment, lay advice seeking and medical advice seeking). Results: The self-reported prevalence of psychological symptoms in the past month was 38.0% (381/1,002). Multivariate analysis for the presence of self-reported psychological symptoms revealed that female sex, higher age, the presence of chronic disease, primary education, lay-advice seeking, pain and the presence of anxiety/depression on EQ-5D questionnaire were independently associated with psychological symptoms. Conclusions: Psychological symptoms are a major public health problem in Slovenian general adult population and the selfreported utilization of professional health care services by Slovenian population is high. Other patterns such as lay referral system might have a crucial influence on the final decision to seek medical help
