The Benefits of Believing in Chance or Fate: External Locus of Control as a Protective Factor for Coping with the Death of a Spouse
2010
The death of a spouse is an extremely stressful life event that consequently causes a large drop in life satisfaction. Reactivity to the loss, however, varies markedly, a phenomenon that is currently not well understood. Because lack of controllability essentially contributes to the stressful nature of this incident, the authors analyzed whether individual differences in belief in external control influence the coping process. To examine this issue, widowed individuals ( N = 414) from a large-scaled panel study were followed for the 4 years before and after the loss by using a latent growth model. Results showed that belief in external control led to a considerably smaller decline in life …
Economic comparison between offshore and inshore aquaculture production systems of European sea bass in Italy
2014
Abstract Offshore production system is predicted to increase in the near future driven by the lack of coastal space and lower environmental impacts. The aim of this paper has been to evaluate the economic performance of offshore production system respect to inshore one, by comparing net present value (NPV), discounted payback time (DPBT) and internal rate of return (IRR) of two Italian mariculture farms that produce European sea bass. Results showed a better economic profitability of offshore farm, even if sensitivity analysis revealed that financial indicators of both aquaculture production systems have been very sensitive to market condition changes. So, offshore production system could r…
Determinants of vaccine hesitancy and effectiveness of vaccination counseling interventions among a sample of the general population in Palermo, Ital…
2020
Counteract vaccine hesitancy is a public health priority. Main objectives of the cross-sectional study conducted were to evaluate knowledge, attitudes, and behaviors regarding vaccination issues, to estimate the prevalence of vaccine hesitancy and to estimate the effectiveness of vaccination counseling on community advocacy in a sample of general population. An anonymous validated questionnaire was administered in April 2017 at the main shopping center of Palermo and was followed by tailored vaccination counseling interventions. To estimate the effectiveness of the interventions four main connection parameters to the vaccinarsi.org website were evaluated, in the two months before and after …
Semantics bias in cross-national comparative analyses : Is it good or bad to have "fair" health?
2016
The Health Behavior in School-aged Children is a cross-national study collecting data on social and health indicators on adolescents in 43 countries. The study provides comparable data on health behaviors and health outcomes through the use of a common protocol, which have been a back bone of the study sine its initiation in 1983. Recent years, researchers within the study have noticed a questionable comparability on the widely used item on self-rated health. One of the four response categories to the item “Would you say your health is….?” showed particular variation, as the response category “Fair” varied from 20 % in Latvia and Moldova to 3–4 % in Bulgaria and Macedonia. A qualitative min…
Evaluation of health outcomes in elderly patients with asthma and COPD using disease-specific and generic instruments: the Salute Respiratoria nell'A…
2001
To compare the effects of asthma and COPD on health status (HS) in elderly patients, and to assess the correlation between disease-specific and generic instruments assessing HS.Multicenter, cross-sectional, observational study.The Salute Respiratoria nell'Anziano (respiratory health in the elderly) Study network of outpatient departments.One hundred ninety-eight asthma patients and 230 COPD patientsor = 65 years old.HS was assessed by the Saint George's Respiratory Questionnaire (SGRQ) and five generic outcomes: Barthel's index, 6-min walk test, mini mental state examination, geriatric depression scale (GDS), and quality-of-sleep index. Independent correlates of SGRQ scores were assessed by…
Cadherin 23 is a component of the transient lateral links in the developing hair bundles of cochlear sensory cells
2005
AbstractCadherin 23 is required for normal development of the sensory hair bundle, and recent evidence suggests it is a component of the tip links, filamentous structures thought to gate the hair cells' mechano-electrical transducer channels. Antibodies against unique peptide epitopes were used to study the properties of cadherin 23 and its spatio-temporal expression patterns in developing cochlear hair cells. In the rat, intra- and extracellular domain epitopes are readily detected in the developing hair bundle between E18 and P5, and become progressively restricted to the distal tip of the hair bundle. From P13 onwards, these epitopes are no longer detected in hair bundles, but immunoreac…
Micellar electrokinetic chromatography with bile salts for predicting ecotoxicity of aromatic compounds.
2004
The retention factors of several aromatic compounds were obtained by micellar electrokinetic chromatography (MEKC) using cholate, taurocholate, deoxycholate and deoxytaurocholate as micellar systems. The possibility of using these retention factors to describe and predict several ecotoxicological activities of different aromatic compounds was evaluated. Adequate correlations retention–ecotoxicity (log LC50 in fish and daphnia, log EC50 in green algae and daphnia, chronic values in fish and green algae, bioconcentration factor, and soil sorption coefficient) were obtained for the micellar systems studied. The predictive ability of the models obtained for these micellar systems was compared. …
Presentation and analysis of an original database of the institutional characteristics of developing, in transition and developed countries
2004
The disparity between the development paths followed by the economies of a limited number of countries, known as ‘emerging’, and the bulk of the other developing countries has shown the limitations of previous development strategies. As a consequence, at the beginning of the 1990s, the question of institutions has been propelled to the top of the economic agenda. Theempirical literature has now solidly documented and validated the general relationship between institutions and development. With this as a starting point, attention is now being concentrated on the actual nature of theinstitutional mechanisms at work, the inter-relationships between them and their combined impact on development…
Características de los menores infractores dependiendo del tipo de delito
2015
The aim of this study is to define a profile of juvenile offenders depending on the type of crime (against property or against persons), according to several socio-demographic variables, and a number of indicators of juvenile risk. Participants were 395 adolescents between the ages of 14 and 18 with a criminal record in the juvenile court over a two-year follow-up period. Results showed that in property-related offences the offender is more likely to be male, from an Eastern European country, and with inconsistent parenting. On the other hand, crimes against persons would be committed mostly by girls, Latin American or African juveniles, and with individual factors such as aggressive behavi…
Dynamic chemical devices: photoinduced electron transfer and its ion-triggered switching in nanomechanical butterfly-type bis(porphyrin)terpyridines.
2005
A series of butterfly-type molecular constructs has been prepared in good yield by using a double Stille coupling synthetic protocol. They are composed of a terpyridine (terpy) scaffold and two wings composed of appended porphyrins that are capable of switching from an extended W geometry to a compact U geometry upon cation coordination of the terpy unit. The porphyrin moieties exist in the constructs either as free bases or they can be sequentially metallated, thus giving rise to wings of different "colours". Stationary and time-resolved emission studies of the HZn, ZnAu and Zn2Au constructs show that the electronic properties are strongly dependent on the geometry. In the extended W confo…
