The Impact of Family and Work-Life Balance Policies on the Performance of Spanish Listed Companies
2014
Work-life balance has become a topic of great relevance in today's business world. In this work we present both a theoretical review on the state of art in this issue and an analysis testing the validity of the positive impact of work-life balance policies in firm performance. For the empirical analyses of these policies on performance we evaluated a sample composed of firms listed in IBEX-35. Findings provide support for the idea that introducing work-life balance practices benefits the company with respect to talent retention and higher employee engagement, as well as achieving a positive impact on productivity, costs and business results.
Esteettisen kritiikki : moderni kokemus ja esteettinen teoria

The efficacy of balneotherapy, mud therapy and spa therapy in patients with osteoarthritis: an overview of reviews.
2021
Osteoarthritis is a degenerative disease considered a leading cause of functional disability. Its treatment is based on a combination of pharmacological and non-pharmacological interventions, but the role of these latter is still debated. This overview of systematic reviews aimed at evaluating the short-term efficacy of different thermal modalities in patients with osteoarthritis. We searched PubMed, Scopus, CINHAL, Web of Science, ProQuest and the Cochrane Database of Systematic Reviews from inception until October 2020, with no language restrictions. We selected the following outcomes a priori: pain, stiffness and quality of life. Seventeen systematic reviews containing 27 unique relevant…
Bioaccumulation of hepatotoxins : A considerable risk in the Latvian environment
2014
Abstract The Gulf of Riga, river Daugava and several interconnected lakes around the City of Riga, Latvia, form a dynamic brackish-freshwater system favouring occurrence of toxic cyanobacteria. We examined bioaccumulation of microcystins and nodularin-R in aquatic organisms in Latvian lakes, the Gulf of Riga and west coast of open Baltic Sea in 2002–2007. The freshwater unionids accumulated toxins efficiently, followed by snails. In contrast, Dreissena polymorpha and most lake fishes (except roach) accumulated much less hepatotoxins. Significant nodularin-R concentrations were detected also in marine clams and flounders. No transfer of nodularin-R and microcystins between lake and brackish …
Analytical methods to determine cocaine contamination of banknotes from around the world
2008
Abstract The presence of cocaine in a significant number of UK pounds (Xxxx), Euros (€) and North American banknotes ($) in general circulation requires appropriate tools to do determinations. This article discusses the-state-of-the-art in the analysis of cocaine on banknotes. We summarize the usual extraction methods of currency samples and compare them, especially with respect to avoiding sample damage. We critically discuss analytical methods, namely gas chromatography (GC) and liquid chromatography (LC), capillary electrophoresis (CE), immunoassay, thermal desorption tandem mass spectrometry (TD-MS2) and ion-mobility spectrometry (IMS). We also review cocaine levels on banknotes around …
Fundamentals and applications of stir bar sorptive dispersive microextraction: A tutorial review
2021
Current trends in sample preparation focus on the miniaturization of the process resulting in what is known as microextraction techniques. Among them stir bar sorptive dispersive microextraction (SBSDME) is one of the most recent techniques. It was presented a few years ago as a hybrid microextraction technique that combines the principles of stir bar sorptive extraction (SBSE) and dispersive solid phase extraction (DSPE). This novel technique introduces, into the sample solution, a bar-shaped magnet coated with a magnetic (nano)material, which is maintained on the surface by magnetism. Once stirring starts, the competitive action between magnetism and rotational force is exploited. At low …
Predicting soil loss in central and south Italy with a single USLE-MM model
2018
Purpose: The USLE-MM estimates event normalized plot soil loss, Ae,N, by an erosivity term given by the runoff coefficient, QR, times the single-storm erosion index, EI30, raised to an exponent b1> 1. This modeling scheme is based on an expected power relationship, with an exponent greater than one, between event sediment concentration, Ce, and the EI30/Pe(Pe= rainfall depth) term. In this investigation, carried out at the three experimental sites of Bagnara, Masse, and Sparacia, in Italy; the soundness of the USLE-MM scheme was tested. Materials and methods: A total of 1192 (Ae,N, QREI30) data pairs were used to parameterize the model both locally and considering all sites simultaneously. …
Det vanskelige foreldreskapet : en studie av foreldre som har deltatt på kurs til foreldre med barn i fosterhjem : deres egenopplevelse av sitt forel…
2007
Regionalt Fosterhjemsarbeid avd. Kristiansand, Barne-, ungdoms- og familieetaten i region Sør arrangerte et kurs til foreldre med barn i fosterhjem vinteren 2006. Studien Det vanskelige foreldreskapet er blitt til ved at Regionalt fosterhjemsarbeid i Bufetat, avd. Kristiansand henvendte seg til PRAXIS – Sør/ Høgskolen i Agder v/ Institutt for sosiologi, sosialt arbeid og velferdsfag og ba om bistand til en oppsummering av foreldrenes opplevelse av egensituasjon og hvordan de har opplevd å delta på kurset. Studiens problemstillinger er, Hvordan presenterer foreldre som har deltatt på kurs til foreldre med barn i fosterhjem sin situasjon? Hvordan presenterer foreldre med barn i fosterhjem sit…
An adaptive-PCA algorithm for reflectance estimation from color images
2008
This paper deals with the problem of spectral reflectance estimation from color camera outputs. Because the reconstruction of such functions is an inverse problem, stabilizing the reconstruction process is highly desirable. One way to do this is to decompose reflectance function on a basis functions like PCA. The present work proposes an algorithm making PCA adaptive in reflectance estimation from a color camera output. We propose to adapt the PCA basis derivation by selecting, for each sample, the more relevant elements from the training set elements. The adaptivity criterion is achieved by a likelihood measurement. Finally, the spectral reflectance estimation results are evaluated with th…
Ladri di luce. Leonardo Sciascia e Piero Guccione tra bellezza e verità
2023
The unpublished correspondence between Leonardo Sciascia and Piero Guccione from 1975 to 1989 shows the profound charge of humanity that innervates the friendship between these two great Enlightenment leaders "upside down". A "correspondence of amorous senses", despite the inevitable ideological differences, which the letters reproduced here for the first time and the original contributions of the volume give us back, under the banner of the binomial "beauty-truth".
