New orbital ephemerides for the dipping source 4U 1323-619: Constraining the distance to the source

2016

4U 1323-619 is a low mass X-ray binary system that shows type I X-ray bursts and dips. The most accurate estimation of the orbital period is 2.941923(36) hrs and a distance from the source that is lower than 11 kpc has been proposed. We aim to obtain the orbital ephemeris, the orbital period of the system, as well as its derivative to compare the observed luminosity with that predicted by the theory of secular evolution. We took the advantage of about 26 years of X-ray data and grouped the selected observations when close in time. We folded the light curves and used the timing technique, obtaining 12 dip arrival times. We fit the delays of the dip arrival times both with a linear and a quad…

Renta de emergencia familiar en Gandia

2011

Sensible ante la situación económica y de nuevas necesidades emergentes, el Ayuntamiento de Gandia, como principal promotor de políticas sociales, considera necesario integrar dentro de sus iniciativas para promover la igualdad, la solidaridad y la mejora de la calidad de vida, un recurso económico para paliar las distintas situaciones en las que se encuentran familias sin ingresos debido a que los adultos integrantes de la unidad familiar se encuentran en situación de desempleo. Se impulsa, como respuesta a estas nuevas necesidades, una prestación de carácter periódico denominada Renta de Emergencia Familiar (REF) que viene acompañada de un conjunto de actuaciones de carácter municipal dir…

La selección de las noticias en el entorno de un centro de documentación de información de actualidad

2002

In information retrieval systems operation, lack of adequate selection criteria originates information overload and has negative consequences in relevance judgments. In the context of a news reference service, three leveis in the selection process are proposed. The first one relates to the type of sources covered by the system, the second set of criteria determines which publications are included in the process of document analysis. The last one applies to the selection of individual documents based on their informative content. La falta de criterios idóneos de selección puede provocar un grave problema de saturación informativa, lo que repercute negativamente en la búsqueda posterior de in…

Rearrangement of N-(3-pyridyl)nitramine

2009

AbstractContrary to other N-(pyridyl)nitramines, the title compound cannot be rearranged to 3-amino-2-nitropyridine or other isomers. Hypothetical products of its transformation under influence of concentrated sulphuric acid, viz. 3-hydroxypyridine, 3,3′-azoxypyridine and 3,3′-azopyridine, were obtained from 3-nitro- and 3-aminopyridine in oxidation and reduction reactions. N-(3-Pyridyl)nitramine was prepared and rearranged in concentrated sulphuric acid. 3-Hydroxypyridine and 3,3′-azoxypyridine were isolated from the reaction mixture, other products were identified by the HPLC and GCMS methods. The results indicate that N-(3-pyridyl)hydroxylamine is an intermediate formed from N-(3-pyridyl…

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and its Role in Conservation of Cacti and Other Succulent…

2007

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) contributes to nature conservation by regulating international trade in listed species by means of a permit system. Through this control system all parties assist in maintaining the listed rare and threatened species in the wild. CITES allows trade in wild specimens up to a level that is not detrimental for the survival of the species in the wild, that is, a use of nature commonly referred to as sustainable use. The basis of CITES are discussed with special emphasis on the Cactaceae and other succulent plants included in the Convention. The framework of regulation of plants in trade is outlined and t…

IT engagement as a blessing and a curse? Examining its antecedents and outcomes in organizations

2020

Information technology (IT) engagement is defined as a need to spend more time using IT. Practice-based examples show that IT engagement can have adverse effects in organizations. Although users can potentially get more work done through IT engagement, observations show that the users might jeopardize their well-being and hamper their work performance. We aimed to investigate this complexity in the research on IT engagement by examining its potential antecedents and outcomes in organizations. Considering the potentially mixed outcomes, we developed a model to examine the effects of IT engagement on personal productivity and strain. We also aimed to explain the antecedents of IT engagement b…

Normativity, moral realism, and unmasking explanations

2004

Moral Projectivism must be able to specify under what conditions a certain inner response counts as a moral response. I argue, however, that moral projectivists cannot coherently do so because they must assume that there are moral properties in the world in order to fix the content of our moral judgements. To show this, I develop a number of arguments against moral dispositionalism, which is, nowadays, the most prom- ising version of moral projectivism. In this context, I call into question both David Lewis' dispositionalist account of colour and Chistine Korsgaard's procedural realism.

This interesting volume was published by the Laterza in 2011 and is the product of fruitful collaboration between three internationally renowned scholars, each with different research perspectives. They are respectively Carla Bazzanella, who teaches General and Cognitive Linguistics at the University of Turin; Rosa Pugliese, who teaches Italian as a foreign language at the University of Bologna; Erdling Strudsholm, who teaches Italian linguistics at the University of Copenhagen.

Loneliness, subjective health complaints, and medicine use among Finnish adolescents 2006-2018.

2022

Aims: Loneliness is an important public health challenge for all ages. This study reports time trends of loneliness among adolescents over a 12-year period and analyses the strength of the associations between loneliness, health complaints, and medicine use. Methods: Data were derived from the cross-sectional Finnish Health Behaviour in School-aged Children study conducted in 2006, 2010, 2014, and 2018. The study population is based on a random sample of schools with 20,444 participants aged 11–15 years. The trends were analysed with a Mantel–Haenszel test, and the strength of the associations was evaluated by mixed-effects logistic and linear regressions. Results: An increasing prevalence …
