Aménités urbaines et périurbaines dans une aire métropolitaine de forme fractale
2002
In the THÜNEN tradition, Urban Economy is a striking abstraction, giving models that keep the main features of the wide diversity of real word cities. Nevertheless, this paradigm less suits the modern urban spatial structures (polycentrism, weak centripetal forces, etc.), particularly the peri-urban form of metropolitan areas, which are an urban/rural integrated space. In this paper, we propose a classical micro-economic urban model combined with a " SIERPINSKI's carpet " geometry, a fractal form which suits for fit together urban and rural areas in a hierarchical structure. Subject to a budget constraint, a household maximises a Cobb-Douglas/CES function, where household's taste for divers…
Ātro kredītu līgumu tiesiskās īpatnības
2015
Nebanku kreditēšanas nozare pēdējo gadu laikā ir strauji ieguvusi un turpina iegūt arvien plašāku klientu loku. Nozares peļņa pēdējos četros gados augusi astoņas reizes. Ātro kredītu izsniedzēji turpina gūt peļņu no cilvēkiem, kuriem, citu aizdevēju ieskatā, nemaz nedrīkstētu aizdot. Nozares ātrās attīstības dēļ, tā nav pietiekami regulēta – nosakot vienus ierobežojumus, tiek atrasti citi veidi, kreditētājiem izdevīgākai aizdošanai, kas nav ierobežoti. Par galvenajām problēmām tiek uzskatītas ātro kredītu nesamērīgās izmaksas un aizņēmēju maksātspējas neizvērtēšana. Darbā autors analizē ātrā kredīta līguma paraugu, īpašu uzmanību vēršot uz noteikumiem, kas attiecas uz piemērojamajiem procen…
Macroalgal responses to ocean acidification depend on nutrient and light levels
2015
Ocean acidification may benefit algae that are able to capitalize on increased carbon availability for photosynthesis, but it is expected to have adverse effects on calcified algae through dissolution. Shifts in dominance between primary producers will have knock-on effects on marine ecosystems and will likely vary regionally, depending on factors such as irradiance (light vs. shade) and nutrient levels (oligotrophic vs. eutrophic). Thus experiments are needed to evaluate interactive effects of combined stressors in the field. In this study, we investigated the physiological responses of macroalgae near a CO2 seep in oligotrophic waters off Vulcano (Italy). The algae were incubated in situ …
Assessing the Commodity Market Price and Terms of Trade Exposures of Macroeconomy in Emerging and Developing Countries
2021
This paper provides novel evidence on commodity market exposure, i.e., the impacts of commodity price and terms of trade fluctuations on macro performance amongst 46 emerging and developing countries (EMDCs) in Africa, Asia and the Latin American and Caribbean (LAC) region. We estimate the exposure of six macroeconomic variables to the commodity prices and terms of trade. Our results indicate that in overall terms, there is a strong and statistically significant long-run relationship between the vector of analyzed world trade prices and macro variables in all EMDCs. However, based on the short-term reactions, only about 10% of the macroeconomic variation amongst the EMDCs is due to commodit…
Happy heart syndrome. frequency, characteristics, and outcome of takotsubo syndrome triggered by positive life events
2021
Background: The association with a preceding stressor is a characteristic feature of takotsubo syndrome (TTS). Negative emotions before TTS are common and led to the popular term "broken heart syndrome." In contrast, pleasant triggers ("happy heart syndrome") are rare and are scarcely investigated. Objectives: The authors analyzed the frequency, clinical characteristics, and prognostic implications of positive emotional stressors in the multicenter GEIST (GErman-Italian-Spanish Takotsubo) Registry. Methods: Patients enrolled in the registry were categorized according to their stressors. This analysis compared patients with pleasant emotional events with patients with negative emotional even…
Testing a spectral-based feature set for audio genre classification
2011
Automatic musical genre classification is an important information retrieval task since it can be applied for practical purposes such as the organization of data collections in the digital music industry. However, this task remains an open question because the current state of the art shows far from satisfactory outcomes in terms of classification performance. Moreover, the most common algorithms that are used for this task are not designed for modelling music perception. This study suggests a framework for testing different musical features for use in music genre classification and evaluates the performance of this task based on two musical descriptors. The focus of this study is on automa…
Business models for internationalization: an analysis on traditional manufacturing smes
2021
Small and medium-sized enterprises (SMEs) are a fundamental actor for the economic and social development of nations. However, these companies have poorer survival prospects than large firms (Freeman, Carroll and Hannan, 1983) and find it difficult to grow abroad (Crick and Barr, 2007). In the case of SMEs in traditional manufacturing industries, in addition to the limitations associated with their small size, there are also difficulties in maintaining competitiveness suffered by non-knowledge-intensive companies (Pla-Barber, Villar and Benito-Sarriá, 2020). For this reason, survival problems and barriers to internationalization are even more prevalent in traditional manufacturing SMEs. The…
Drivers of job-related learning among low-educated employees in the Nordic countries
2018
This study explored drivers of participation in job-related lifelong learning (LLL) among low-educated mature-aged employees and compared them across four Nordic countries. Workplaces can be low-threshold, effective arenas for development of their skills in work and learning. The paper builds on the Bounded Agency Model and theories of learning motivation, human capital, and workplace learning. We used data from the Survey of Adult Skills (Programme for the International Assessment of Adult Competencies) by Organisation for Economic Co-operation and Development. The average participation rate was 36%. Results of the logistic regression analyses showed that income, skills use at work, sector…
Perceptions of digital technology in nursing education: A qualitative study.
2021
Abstract Aim The aim of this study was to explore how digital technologies can facilitate interactive learning in a 15-credit theory module on basic nursing. Background Digital platforms are in widespread use in nursing education; however, the rapid technological advancement provides new opportunities to support teaching and learning. This indicates the need to explore how educational digital technologies can be used as an integral part of learning activities to promote quality and relevance in nursing education. This study was carried out at the Department of Nursing Science at a university in Norway. The university has been using a digital platform for many years and has recently adopted …
High testosterone levels and sensitivity to acute stress in perpetrators of domestic violence with low cognitive flexibility and impairments in their…
2013
Hormonal and neuropsychological impairment in intimate partner violence (IPV) perpetrators could play a role in domestic violence. For characterizing whether there is a specific psychobiological response to stress, participants who had previously been jailed for IPV and controls were compared for testosterone and cortisol levels, tested for 2D:4D ratio (as an indicator of masculinization), and given several trait questionnaires and neuropsychological tests related to executive functions and theory of mind. After performing the Trier Social Stress Test (TSST), IPV perpetrators experienced decreases in salivary testosterone (T) levels, a moderate worsening of mood, slight anxiety, and a saliv…
