Certain advantages of Scopus compare with Web of Science in a bibliometric analysis related to smoking

2013

El objetivo de este trabajo es comparar entre Web of Science (WoS) y Scopus los indicadores bibliométricos básicos del área de tabaquismo de autores españoles en el período 2000-2009. Métodos: La búsqueda se realizó en el SCI-Expanded y Scopus (“smok*” OR “tobac*”). Resultados: La media total anual del nº de documentos fue de 41 ± 12 para WoS vs 60 ± 16 en Scopus (p = 0,007). Aumento progresivo del índice de colaboración. La media anual del índice de colaboración fue de 9,41 ± 2,73 en WoS vs 7,12 ± 1,52 en Scopus (p = 0,029). Mayor número de citas con el paso del tiempo en ambas bases de datos pero son más recientes las citas en Scopus, el índice citas/artículo fue mayor en WoS (WoS 14,47 v…

We examined the sustainability of the KiVa antibullying program in Finland from its nationwide roll-out in 2009 to 2016. Using latent class analyses, we identified four different patterns of implementation. The persistent schools (43%) maintained a high likelihood of participation throughout the study period. The awakened (14%) had a decreasing trend during the first years, but then increased the likelihood of program participation. The tail-offs (20%) decreased in the likelihood of participating after the third year, and the drop-offs (23%) already after the first year. The findings suggest that many schools need support during the initial years to launch and maintain the implementation of…

Scientific Literature Among Smoking and Respiratory System: Repercussion and Collaboration

2012

a b s t r a c t Aim: To analyze the distribution of the production, repercussion and co-authorship of articles on smok- ing in the "respiratory system" category through the Science Citation Index Expanded (SCI-E) and their inclusion in the first quartile of the Journal Citation Report (JCR). Methods: The literature search was performed in the SCI-E. Articles were selected for 2001-2010 for "respiratory system" using the descriptors "smok*" and "tobac*". Results: We found 1858 articles (ignoring collaboration) on the topic of smoking. The median number of published articles by five-year period was higher for the 2006-2010 period vs the 2001-2005 period; in contrast, the number of citations a…

Medida del resultado de las intervenciones sanitarias en España: una aproximación mediante el análisis temporal y espacial de la mortalidad evitable …

2006

Fundamento: Muchos estudios proponen la mortalidad evitable (ME) como indicador para monitorizar los servicios de salud aunque su generalización está limitada por el gran número de listas de causas utilizadas. El objetivo es analizar la evolución temporal del período 1986-2001 y la distribución geográfica de la mortalidad evitable utilizando una lista de causas consensuada. Métodos: Se analiza la mortalidad evitable global (ME) y agrupada en causas ISAS (intervenciones de los servicios sanitarios) y causas IPSI (políticas intersectoriales). Se analiza la evolución temporal ajustando una recta de regresión de Poisson o un modelo de regresión de Joinpoint, según el caso, y se estima el porcen…

Size-dependent tradeoffs in aggressive behavior towards kin

2020

AbstractAggression between juveniles can be unexpected, as their primary motivation is to survive until their reproductive stage. However, instances of aggression, which may escalate to cannibalism, can be vital for survival, although the factors (e.g. genetic or environmental) leading to cannibalism vary across taxa. While cannibalism can greatly accelerate individual growth, it may also reduce inclusive fitness when kin are consumed. As a solution to this problem, some cannibals demonstrate kin discrimination and preferentially attack unrelated individuals. Here, we used both experimental and modeling approaches to consider how physical traits (e.g. size in relation to opponent) and genet…

Conflict in Somalia: impact on child undernutrition

2017

Background: In Somalia, protracted conflict and persistent drought have caused population displacement and livelihood destruction. As a result, there is widespread child malnutrition. We aimed to determine the effects of conflict on wasting and stunting among children aged 6-59 months in Somalia 2007–2010.\ud \ud Methods: Data were from household nutritional surveys from 2007 to 2010, with 1,066 clusters covering 73,778 children, the Armed Conflict Location and Event Data (ACLED) project and remote sensing. We used Bayesian hierarchical spatial-temporal regression methods to examine the effects of conflict on wasting and stunting. A preliminary model included individual, household and envir…

The Access of the Young Graduates in Sciences into R&D Profession: A Switching Model Treatment for the French Case

2011

We address the question concerning the choice of graduates in sciences and engineering to look for employment in research and development. We use an endogenous switching regression to avoid the existence of self-selection biases. The study shows that human capital is decisive where both employment opportunities and remuneration are concerned within, but not without, this sector. The results also suggest that in the early stages of a career, the R&D sector is less rewarding than other types of employment only for doctors and not for graduates from engineering schools.

Household skills and low wages

2008

Originally published in the journal Journal of Population Economics, Springer http://www.springerlink.com/content/100520/ Household skills provide job skills when tasks in jobs and household production are similar and jobs produce substitutes for home-made services. Opportunity costs of higher education are foregone earnings during schooling and foregone household production while studying and later in life. I show that individuals in jobs requiring household skills accept lower wage rates than traditional human capital theory predicts, and that individuals with low household skills tend to enter higher education. According to these results, declining household skills may have contributed t…
