Developing the "Choosing Health" Digital Weight Loss and Maintenance Intervention: Intervention Mapping Study
2022
Background Digital health promotion programs tailored to the individual are a potential cost-effective and scalable solution to enable self-management and provide support to people with excess body weight. However, solutions that are widely accessible, personalized, and theory- and evidence-based are still limited. Objective This study aimed to develop a digital behavior change program, Choosing Health, that could identify modifiable predictors of weight loss and maintenance for each individual and use these to provide tailored support. Methods We applied an Intervention Mapping protocol to design the program. This systematic approach to develop theory- and evidence-based health promotion …
Factores determinantes y consecuencias de la adopción del comercio electrónico B2C: una comparativa internacional
2012
Numerosas empresas minoristas han decidido crear tiendas virtuales como alternativa a la tienda física. El presente trabajo pretende analizar los factores que influyen en esta decisión estratégica y su impacto sobre los resultados del negocio entre los principales minoristas del Reino Unido, Francia y España. A partir de una regresión binaria y del análisis de la varianza, los resultados muestran que la adopción del comercio electrónico por el minorista es afectada por el tamaño de la empresa, el tipo de bien comercializado y el país donde se ubica el establecimiento. Asimismo, se observan diferencias significativas en términos de beneficio y rentabilidad entre los minoristas que han adopta…
Bezastaino abinieku Anura sugu sastāvs un izplatība pilsētvides ūdenstilpēs Daugavpilī
2022
Mūsdienās abinieki pasaulē ir viena no visvairāk apdraudētām dzīvnieku klasēm. Visos pasaules reģionos ir konstatēta īpatņu skaita samazināšanās vai pilnīga izzušana. Abinieku izmiršanas cēloņi ir dažādi – biotopu pārveidošana, klimata izmaiņas, kā arī sēnīšu Batrachochytrium dendrobatidis izraisīta slimība. Abinieku izzušana ir skaidri redzama pateicoties bezastainajiem abiniekiem, jo tos var viegli gan ieraudzīt, gan saklausīt. Diemžēl šī problēma varētu skart arī Latvijas abiniekus. Bakalaura darba mērķis ir noteikt, kādas bezastaino abinieku sugas ir sastopamas Daugavpils ūdenstilpēs, kā arī noteikt aptuveno populācijas lielumu, pamatojoties uz pieaugušo varžu un krupju tēviņu dziesmu i…
Effects of ecological flooding on the temporal and spatial dynamics of carabid beetles (Coleoptera, Carabidae) and springtails (Collembola) in a pold…
2011
Within the scope of the Integrated Rhine Program an ecological flood gate and channel was inserted into the polder “Ingelheim” to enhance animal and plant diversity. In 2008, carabid beetles and springtails were collected, using pitfall traps, to measure the effects of ecological flooding and a strong precipitation event at a flood-disturbed and a dry location in this area. At both localities, xerophilic and mesophilic carabid beetle species were dominant throughout the study period. The total number of individuals of hygrophilic species was comparatively constant, while species number increased, partly due to the changed moisture conditions caused by ecological flooding and str…
Role of Surface Chemistry in the Superhydrophobicity of the Springtail Orchesella cincta (Insecta:Collembola)
2020
Collembola are ancient arthropods living in soil with extensive exposure to dirt, bacteria, and fungi. To protect from the harsh environmental conditions and to retain a layer of air for breathing when submerged in water, they have evolved a superhydrophobic, liquid-repelling cuticle surface. The nonfouling and self-cleaning properties of springtail cuticle make it an interesting target of biomimetic materials design. Recent research has mainly focused on the intricate microstructures at the cuticle surface. Here we study the role of the cuticle chemistry for the Collembola species Orchesella cincta (Collembola, Entomobryidae). O. cincta uses a relatively simple cuticle structure with prima…
The Influence of Requirements in Software Model Development in an Industrial Environment
2017
Textual description of requirements is a specification technique that is widely used in industry, where time is key for success. How requirements are specified textually greatly depends on human factors. In order to study how requirements processing is affected by the level of detail in textual descriptions, this paper compares enriched textual requirements specifications with non-enriched ones. To do this, we have conducted an experiment in industry with 19 engineers of CAF (Construcciones y Auxiliares de Ferrocarril), which is a supplier of railway solutions. The experiment is a crossover design that analyzes efficiency, effectiveness, and perceived difficulty starting from a written spec…
Holes in the Dike: The Global Savings Glut, U.S. House Prices and the Long Shadow of Banking Deregulation
2016
We explore empirically how capital inflows into the US and financial deregulation within the United States interacted in driving the run-up (and subsequent decline) in US housing prices over the period 1990-2010. To obtain an ex ante measure of financial liberalization, we focus on the history of interstate-banking deregulation during the 1980s, i.e. prior to the large net capital inflows into the US from China and other emerging economies. Our results suggest a long shadow of deregulation: in states that opened their banking markets to out-of-state banks earlier, house prices were more sensitive to capital inflows. We provide evidence that global imbalances were a major positive funding sh…
A simple operation strategy of battery storage systems under dynamic electricity pricing: An Italian case study for a medium-scale public facility
2014
In the electricity market, wholesale energy prices depend on the balance between energy production and load demand. In the last few years, electricity market has become more and more flexible as many utilities have started to replace the fixed retail prices schemes with prices changing during the day. Dynamic pricing, also known as Real-Time Pricing (RTP), reflects the trend of the wholesale market and allows to reduce the volatility of the wholesale prices, also contributing to a reduction of demand peaks. Electricity customers take advantage of dynamic pricing by shifting their consumption according to the real-time prices or by using Battery Energy Storage Systems (BESS) to shift electri…
Economic feasibility of a customer-side energy storage in the Italian electricity market
2015
Electricity prices show significant short-term variations during the day due to the need of balancing supply and demand in real time. Normally, customers are not exposed to these variations but pay a constant electricity price. In an attempt to reduce the volatility of the wholesale prices, several utilities are moving from conventional fixed-rate pricing schemes to new market-based models, where the electricity price can fluctuate during the day depending on the market conditions. Examples of time-dependent pricing schemes are Time-Of-Use (TOU) tariffs, where the electricity price can take two or three price levels during the day, or Real-Time Pricing (RTP) tariffs, where the energy price …
Risk Management Era in European Credit Institutions: Predictable Mutation in XXI Century
2014
Abstract In the market economy, globalization, liberalization and diversification of financial markets, fierce competition between the credit institutions and many of the products and services offered by them are the main factors that have exposed the banking sector to new risks, while leading to multiple challenges. For these reasons it is becoming increasingly important both permanent innovation and risk management techniques tools as well as banking performance. Only a pertinent analysis and a very good knowledge of the new tendencies in banking financial risk management can provide credit institutions in Romania efficient options on their use of management, while obtaining a higher prof…
