Krankheitsbewältigung bei Patienten nach Lebertransplantation unter Berücksichtigung der Zugehörigkeit zu einer Selbsthilfegruppe

2002

Background: Within the past 15 years, liver transplantation has proven itself to be the treatment of choice among patients with terminal liver disease. The one-year survival rate is about 80%; after 8 years 61 % of the patients are still alive. The present study investigates the influence of active or depressive coping on the physical and mental quality of life in two different groups of patients after liver transplantation. Methods: Members (n = 65) and non-members (n = 2,0) of a German self-help group were asked to fill out a postal survey. Patients were included if their liver transplantation was conducted 6 to 36 months ago. The health-related quality of life was surveyed using the SF-3…

Purpose To analyze the effect of birth weight on ocular morphology, refraction and visual function in early adolescents aged 12–15 years. Material and methods We conducted a secondary data analysis using the public use files from the National Health and Nutrition Examination Survey of the period from 1999 to 2008. Study participants aged 12 to 15 years were included with data on birth weight and ophthalmic parameters including presenting distance visual acuity, objective refraction and keratometry. Visual acuity, sphere, astigmatism in power vectors J0 and J45, corneal power and corneal astigmatism were evaluated for an association with birth weight. Linear and logistic regression with adju…

Beliefs and Experiences of Individuals Following a Zero-Carb Diet

2021

The adoption of carbohydrate-restrictive diets to improve health is increasing in popularity, but there is a dearth of research on individuals who choose to severely restrict or entirely exclude carbohydrates. The present study investigated the beliefs and experiences of individuals following a diet that severely limits, or entirely excludes, dietary carbohydrates, colloquially known as a ‘zero-carb’ diet, for at least 6 months. Zero-carb dieters (n = 170) recruited via a social networking site completed an online qualitative survey prompting them to discuss their motives, rationale, and experiences of following a low-carb diet. Transcripts of participants’ responses were …

EFFECTS OF SOCIAL ISOLATION ON MENTAL HEALTH DURING COVID-19 IN THE CONTEXT OF AGEING

2021

The COVID-19 pandemic brought significant changes to the usual rhythm of life. Reduced opportunities to meet with family members and friends in a situation of heightened stress leads to increased feelings of loneliness and social isolation, as well as increases the risk of mental health problems. The aim of this paper is to evaluate the effect of social contacts on the changes in psychoemotional states in the elderly population in Latvia during the crisis caused by the COVID-19 pandemic. The analysis draws upon quantitative data collected by the Survey of Health, Ageing and Retirement in Europe within Wave 8 in Latvia (n=1207). Measurements of the frequency of social contacts were used to c…

Entrepreneurial choices depend on trust : Some global evidence

2022

Interpersonal trust and people’s trust in institutions are important components of social capital, which has been shown to have not only innate social value but also diverse direct and indirect positive social and economic impacts. Using data for an economically and globally diverse group of countries, we examine empirically how changes in interpersonal trust and trust in institutions affect entrepreneurship over time. Our findings suggest that (1) enhancing either type of trust leads to more entrepreneurial activity and (2) an increase in interpersonal trust causes a structural change in the composition of the TEA-type entrepreneurship. Increased trust reduces the share of relatively lower…

Estudo sobre o Global Report Initiative de empresas de energia elétrica dos Estados Unidos, do Brasil e da Espanha no período de 1999 a 2010

2013

Para atender às demandas sociais e organizacionais, vários instrumentos têm surgido para auxiliar o processo de geração de informações ambientais, entre eles o Global Reporting Initiative (GRI). Desde 1999, o GRI vem auxiliando as empresas a medirem e comunicarem seu desempenho econômico, ambiental e social. Sua consolidação ao longo da década de 2000 tornou-o um instrumento de grande aceitação pelas organizações e pela sociedade e, como consequência, tornou-se foco de estudos científicos sobre sustentabilidade (econômica, social e ambiental) nas organizações. Neste contexto, emerge a pergunta da atual pesquisa: Qual o perfil das empresas do setor elétrico listadas no GRI? Para responder a …

Multitemporal analysis of PAL images for the study of land cover dynamics in South America

2006

Pathfinder AVHHR Land (PAL) database has been used for the retrieval of Land Surface Temperature (LST) over South America, which, along with NDVI parameter, will allow the studying of the evolution of the vegetation between July 1981 and September 2001. To this end, a classification has been built, based on PAL NDVI and Reanalysis air temperature at 2 m height data. This classification takes into account both vegetation and thermal patterns, and has been validated by a comparison with CAZALAC's map of arid zones (Centro del Agua para Zonas Aridas y semiaridas de Latino-America y el Caribe), as well as with Global Land Cover Characteristics' classification built by the USGS (United States Ge…

Simulation models in eGovernment using system dynamics: A literature survey

2016

System Dynamics (SD) is a method to build simulation models using computers, to study the behaviour of systems, and apply what-if scenarios aiming at achieving optimal policy design. To have an overview of the current state-of-the-art of SD use in the eGovernment field; we have surveyed related literature. Our main goal is to uncover the possibilities for future research by clarifying the shortages. The identified literature is not very large. In most of the literature, SD models use was limited to SD practitioners. We discovered low usage of Group Model Building and workshops despite their usefulness in involving non-SD practitioners in the model building process. Additionally, there is a …

Religion and Social Integration in France

2013

On some measures, France has the most integrated (and secularised) Muslim population in Europe. For example, attitude research shows that French Muslims share values closer to those of their non-Muslim neighbours than in other European countries (Connor 2010 391). While official sources of data are limited as the French government does not collect statistics organised by religion, ethnicity or any other form of collective identity, a number of private and international surveys have been carried out. Thus, the European Values Survey (2002–6 data) shows that rates of religious observance for Muslims in France are closer to those amongst the majority population than in either Britain or the Ne…

How is the current clinical management of endometrial cancer worldwide? An international survey by the North-Eastern German Society of Gynaecological…

2012

5087 Background: Indication, technique and extent of lymph-node-dissection (LND) in endometrial cancer (EC) remains controversial and is strongly debated in cancer community. We conducted a national- and at a second step an international-survey evaluating the current status-quo of the surgical and medical management of EC. Methods: A validated 15-item-questionnaire regarding surgical and adjuvant procedures of EC was sent to all major gynaecological cancer societies and study groups worldwide. The questionnaire could also be answered online. Results: In a phase-I-national trial, the questionnaire was validated on basis of 316 German institutions. On the phase-II-international survey a tota…
