Water Stress Estimation from NDVI-Ts Plot and the Wet Environment Evapotranspiration  [PDF]
Daniela Girolimetto, Virginia Venturini
Advances in Remote Sensing (ARS) , 2013, DOI: 10.4236/ars.2013.24031
Abstract:

In this work we present a new simple index to estimate water stress (WS) for different types of surfaces, from remotely sensed data. We derive a WS index, named WSIEw, modifying the Water Deficit Index (WDI) proposed by Moran et al. by using the wet environment evapotranspiration (Ew) instead of the potential evapotranspiration (Epot) concept. Jiang and Islam model was used to simulate actual evapotranspiration (ET) and Priestley and Taylor equation to estimate Ew. The WSIEw results were compared to ground observations of ET, precipitation (PP), soil temperature (Tsoil) and soil moisture (SM) in the Southern Great Plains-EEUU. Preliminary results suggest the method is sensitive to the water status of different surfaces. However, the WSIEw would range from 0 to 0.7, having a value of 0.4 for a dry surface with 5% of SM. The methodology is operationally

Aquifer Vulnerability Assessment Methods: The Non-Independence of Parameters Problem  [PDF]
Daniela Ducci
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.24034
Abstract: This paper investigates the relationship between the two parameters, aquifer media and hydraulic conductiv-ity, and assesses their reliability for aquifer vulnerability assessment. To evaluate the possible non-inde-pendence of the parameters in question, sensitivity analysis procedure was used in a GIS environment. The procedure was tested in three areas where aquifer vulnerability was assessed, corresponding to three different hydrogeological settings. The applications demonstrate that non-independence is confirmed and is more evident in alluvial and volcano-pyroclastic aquifers.
Exploring the Nature of Information Systems Development Methodology: A Synthesized View Based on a Literature Review  [PDF]
Daniela Mihailescu, Marius Mihailescu
Journal of Service Science and Management (JSSM) , 2010, DOI: 10.4236/jssm.2010.32033
Abstract: New Information Systems Development Methodologies (ISDMs) are suggested in the belief that their deployment would be beneficial to consultants in their work. A large number of ISDMs already exist but their value has been questioned and at the same time new methodologies continue to be introduced in an attempt to support and improve the practice of information systems development work. What is not always clear from current studies is that ISDM is a multi-perspective and cross-discipline phenomenon. Although a large amount of knowledge of ISDM is available, different disciplinary interests have resulted in fragmented assessments of it. This paper intends to identify theoretical perspectives applied in the conceptualization of ISDM. A review of the literature on ISDM was conducted and four different theoretical perspectives were identified: 1) system, 2) structure, 3) innovation, and 4) knowledge. While each perspective provides various overarching depictions of ISDM, the synthesized view of ISDM provided in this study reveals the complexities and ambiguities of a multifaceted phenomenon such as ISDM. Suggestions for an alternative conceptualization of ISDM are provided in an attempt to facilitate the investigation of ISDM.
Endoscopic Adenoidectomy Secondary to Druginduced Trismus  [PDF]
Mark Greenberg, Daniela Carvalho
Surgical Science (SS) , 2010, DOI: 10.4236/ss.2010.11006
Abstract: We present the case of a 4 year old girl whose adenoidectomy had to be performed via an endoscopictrans oral approach due to the unexpected inability to fully open the mouth during the procedure. The patient had previously been taking Risperidone for behavioral symptoms associated with her autism. The jaw tone returned to normal following the procedure and there were no complications. An interaction between the Risperidone and the anesthetics were the likely cause of the trismus.
Classification and Selection of Prototyping Activities for Interaction Design  [PDF]
Stefano Filippi, Daniela Barattin
Intelligent Information Management (IIM) , 2012, DOI: 10.4236/iim.2012.44022
Abstract: Because of the evolution of markets and technologies, prototyping concerns should be kept updated almost day by day. Moreover, user centered design moves the focus towards interaction issues. Prototyping activities matching such characteristics are already available, but they are not so diffused in the industrial domain. This is due to many reasons; an important one is that a rigorous classification of them is missing, as well as an effective helping tool for the selection of the best activities, given the design context. The research described in this paper aims at defining a new classification of prototyping activities, as well as at developing a selection algorithm to choose the best ones in an automatic way. These goals are pursued by defining a set of characteristics that allow describing accurately the prototyping activities. The resulting classification is made by five classes, based on eighteen characteristics. This classification is exploited by the first release of an algorithm for the selection of the best activities, chosen in order to satisfy design situations described thanks to a different set of eleven indices. Five experiences in the field have been used up to now as a starting point for validating the research outcomes.
Fighting Against Obesity and Overweight: Approach to Design a New Service in Nutrition Education  [PDF]
Marisela Rodriguez, Daniela Charvel
Journal of Service Science and Management (JSSM) , 2013, DOI: 10.4236/jssm.2013.61011
Abstract:

Overweight and obesity (O&O) are a global public health problem, which many scientists have named as the XXI century epidemic. Since the 80’s decade, the O&O world prevalence has increased both in children and adults, and Mexico is among the highest. Under this context, the main goal of this research is to develop a business model based on a service of nutritional education as a way to fight against O&O. This research proposes a new model founded on a strategic combination of Service Design and Competitive Intelligence methodologies. The aim is to generate a unique and innovative service tailored to customer needs.

Gratitude, or the Positive Side of the Relationship with Patients. Development and First Validation of New Instruments: A Scale of Gratitude Perceived by Operators and a Scale of Support Offered by the Gratitude Expressed by Their Patients  [PDF]
Mara Martini, Daniela Converso
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.56067
Abstract:

The relationship with patients/users is a crucial dimension for helping professionals. It is nevertheless mostly analyzed in its negative connotation, that’s to say as a possible cause, for example, of the burnout syndrome, while very few are research works that take into account the positive side of the relationship, as a resource more than a problem, and even fewer are the instruments to measure it. The aim of the present work is the development and the analysis of the characteristics of a scale to measure the gratitude expressed by patients perceived by operators and of a scale to measure the perception of support that gratitude by patients/customers offers to relieve the fatigue of daily commitment and return significance to their work. The two scales were developed and then integrated into a questionnaire including items regarding the negative side of the relationship (exceeding requests from patients) and the Customer-initiated support scale (Zimmermann et al., 2011). The questionnaire was filled in by 267 nurses in Piedmont, Italy. Descriptive analyses on each item, exploratory factor analysis, Cronbach’s alpha, analysis of variance, and bivariate correlations were conducted. Both scales show a one-factor solution. The independent sample t-tests highlighted differences between men and women and between people who have families to care for and people who do not. Bivariate correlations signalled a positive relationship between both the gratitude scales and the Customer-initiated support; no relationships are evident with the scale of exceeding request from patients. A limitation of the work is the dimension of the sample: a more extensive administration of the questionnaire is currently in progress that will also permit to more deeply investigate the factorial structure of the scales. The scales will allow filling a gap in measuring a central work issue for helping professions.

Influence of the Boundary Forcing on the Internal Variability of a Regional Climate Model  [PDF]
Kevin Sieck, Daniela Jacob
American Journal of Climate Change (AJCC) , 2016, DOI: 10.4236/ajcc.2016.53028
Abstract: The internal variability of a ten-member ensemble of the regional climate model REMO over Europe is investigated. It is shown that the annual cycle of internal variability behaves differently compared to earlier studies that focused on other regions. To gain better insight into the dependence of the internal variability on the boundary forcing variability, a circulation type classification is performed on the forcing data. It can be shown that especially in the winter season internal variability is dependent on the circulation type included in the boundary forcing, whereas in the summer season the level and pattern of internal variability is rather independent from the circulation type of the driving field. It is concluded that for Europe the internal variability of REMO in winter is governed by circulation patterns related to the North-Atlantic Oscillation, whereas in summer local processes play a bigger role.
Feelings Which Strike a Chord, and Chords Which Strike a Feeling  [PDF]
Bernd Willimek, Daniela Willimek
Open Journal of Acoustics (OJA) , 2017, DOI: 10.4236/oja.2017.71002
Abstract: The first part of this article addresses the main premise of the Theory of Musical Equilibration. It states that in contrast to previous hypotheses, music does not directly describe emotions: instead; it evokes processes of the will which the listener identifies with. It is not until these processes are experienced that music appears to take on an emotional character. The second part of the article focuses on demonstrating the emotional nature of musical harmonies. The Basic Test and the Rocky Test are presented. These tests were designed to find correlations between chords and scenes from fairy tales as well as emotional terms. 86% of the participants correlated the musical selection to the emotion outlined by the Theory of Musical Equilibration the authors developed in this context.

Daniela Dimitrova Popova
Open Journal of Yangtze Oil and Gas (OJOGas) , 2018, DOI: 10.4236/ojogas.2018.32011
Abstract: The Oil and Gas Industry is an important branch of the Bulgarian economy. The factors, driving the development of the sector and its companies, include the global market tendencies and demand, specific conditions for business initiatives and launching projects, etc. The aim of the paper is to show some indicators of Oil and Gas Industry of the Republic of Bulgaria and to draw some economic impacts on the improvement of performance and implementation of the sector’s long-term plans, contracts and relationships in development. The main problematic issues of the Bulgarian Oil and Gas industry refer to its dependence upon importers from other countries, the gap between the official expertise (communicated mainly through internet formal documents and official websites of the Bulgarian Oil and Gas companies) and the sector’s priority for the economy, etc. The factors of influence on Oil and Gas Industry of the Republic of Bulgaria could not be unambiguously specified, but they include the global market tendencies, competition in the sector, the launching projects according the Bulgarian government policy and priorities, the prerequisites for improvements in qualification of experts and companies, the implementation of new technological solutions, etc.
