Abstract: During the last few years, the cooperatives savings banks sector is experiencing an important adaptation effort towards a more urban and tertiary environment. Although these cooperatives still retain their market shares in the rural areas, they are putting a strong emphasis in developing and growing within urban areas densely populated, offering a wide spectrum of interesting and competitive banking products. From their beginnings, such entities have shown responsible trends in their social interactions; therefore the social economy as well as the local development and their orientation to the shareholders were backed and encouraged. But this effective establishment of the corporative social responsibility is threatened as these entities develop due to a lesser extent participation of their shareholders, a diversification and of their banking activities and also due to a minor cooperative activity. Thus, taking seriously into account the data published by UNACC, INE and Banco de Espa a (1995-2008) an statistical and also a graphical indepth analysis is conducted to study the evolution and trends regarding the shareholders over customers and on investment credit operations ratios as well as the financial profitability. The intention of the cited study is to underline the role of the shareholder, its financial relevance and its influence on how the cooperative savings bank is managed.

Abstract: background: the human immunodeficiency virus (hiv) epidemic in spain was characterized throughout the first few years by the predominance of infections among injected drug users (idu's), but everything currently points to a progressive predominance of sexual transmission. this study is aimed at describing the trend in hiv infection among several heterosexual populations groups and at characterizing the situations in which the infections occurred. methods: descriptive study of the individuals who had the test conducted for the first time at nine hiv diagnosis centres within the 1992-2003 period due to high-risk heterosexual exposures, not including injected drug users. results: a total of 47,870 individuals had serology performed during the period under study. the hiv prevalence among the population under study dropped from 3.2% to 1.0% (p< 0.001). among the individuals with an hiv infected partners, the prevalence remained at around 10%, the male users of prostitution having dropped from 1.9% to 1.0% (p=0.049); among women involved in prostitution, from 1.4% to 0.7% (p=0.008); and among all other heterosexuals, having dropped from 1.6% to 1.0% among males (p=0.014) and from 1.1% to 0.7% among women (p=0.012). conclusions: the results indicate advances in the control of heterosexual human immunodeficiency virus transmission, mainly among women, although it is necessary to still continue stressing prevention.

Abstract: The aim of this work is to present the important demographic changes that Spain has experimented in the last 50 years, which are marked by an inescapable process of population aging. This fact has been minimized by the large number of foreigners who comes to Spain. Although the guarantee of the pension system is a fact, during the next two decades, it’s needed to carry out some reforms with relative urgency, following the models that the most European countries have already carried out. The purpose of these reforms must be clear and precise, because it is a fact that in the following years will be a great number of retirees and is not so clear that a proportional increase in the number of participants will happen. With respect to the measures to be taken, we think that all of them must be directed to improve the relation between the contributions during the phase of activity and the amount of benefits, once retirement occurs. Finally, it would be desirable that any pension system’s reform would be accompanied by effective measures of economic policy which increase employment, as well as its quality. Key words: Ageing, pensions reform, retirement age, dependency ratio. El objetivo de este trabajo consiste en presentar los importantes cambios demográficos que ha sufrido Espa a en los últimos cincuenta a os, marcados por un ineludible proceso de envejecimiento poblacional, que se ha contrarrestado tímidamente por la afluencia puntual de extranjeros. Aunque la garantía del sistema de pensiones es un hecho, durante las dos próximas décadas, hay que efectuar reformas con relativa urgencia, a imagen y semejanza de las ya realizadas en la mayoría de países europeos. La finalidad de estas reformas debe ser clara y decidida, pues es una certeza que en los próximos a os se atenderá a un número mucho mayor de jubilados y no está suficientemente claro que se produzca un aumento proporcional en el número de afiliados. En cuanto al tipo de medidas a adoptar, creemos todas ellas deben de ir encaminadas a mejorar la relación entre las cotizaciones durante la etapa de actividad y la cuantía de las prestaciones, una vez que se produce la jubilación. Finalmente, sería deseable que toda reforma del sistema de pensiones fuese acompa ada de medidas efectivas de política económica que incrementen el empleo, así como la calidad del mismo. Palabras clave: Envejecimiento, reforma de las pensiones, edad de jubilación, tasa de dependencia.
Replacement of Soybean Meal with Lupin or Chickpea Seed Meal in Diets for Fattening Iberian Pigs Promotes a Healthier Ileal Microbiota Composition  [PDF]

Advances in Microbiology (AiM) , 2014, DOI: 10.4236/aim.2014.49055

Five castrated male Iberian pigs (100 ± 2 kg b.w.) fitted with T-shaped ileal cannulas at the terminal ileum were used to determine the effects of legume feeding on intestinal microbiota composition. The diets were based on defatted soybean (Glycine max), lupin (Lupinus angustifolius) or chickpea (Cicer arietinum) seed meals and contained similar amounts of digestible energy (14.2 - 15.1 MJ·kg-1) and protein (107 g·kg-1). A hydrolyzed casein diet was used to determine the bacterial counts in pigs fed on a vegetable-free diet. The composition of the intestinal microbiota at the terminal ileum was analysed by q-PCR. Higher (P < 0.05) lactobacilli log10 number of copies was determined in the ileal contents of pigs fed on lupin- or chickpea-based diets with respect to those fed on the soybean-based diet. Bacteroides and the Clostridium coccoides/Eubacterium rectale group log10 number of copies was lower (

Abstract: The purpose of this study was to analyze and compare the technical performance profile of the four-time Costa Rican Senior Basketball League championship team. A total of 142 games was recorded throughout the 2007, 2008 and 2009 seasons. Performance indicators selected were: two and three-point shots (converted, missed, effectiveness rates), free throws (converted, missed, effectiveness rates), points, offensive and defensive rebounds, fouls, turnovers, assists and ball steals. The information was described based on absolute and relative frequency values. Data was compared by season and by playing period based on the following non-parametric techniques: U-test, Friedman test and Chi-square. In all cases, SPSS version 15.0 was used with a significance level of p ≤ 0.05. Results showed a better profile of technical performance in the 2008 season, characterized by better percentages of two-point shots, free throws, fewer turnovers and more ball steals and assists. In relation to the playing period, the team showed a better technical performance profile during the second half of the matches. In general, the effectiveness rate of two-point shots and free throws was above 60% in both playing periods, while the three-point shot percentage ranged between 26.4% and 29.2%. In conclusion, the team showed a similar technical performance profile to that reported in the literature, as well as a clear evidence of the importance of recording and following up on technical performance indicators in basketball.

Abstract: This paper provides an overview of the phenomenon of dance in the field of education. At first, it is made a presentation of the different components or aspects of human beings on that dance impacts in a more obvious way. Subsequently, we present a review of the definitions proposed by different authors that we consider most relevant and it is included a personal definition of the concept. It also highlights the contributions of dance to education in terms of social, physical, intellectual and emotional development and identifies the major problems that this discipline has had to be included as a subject: lack of teacher training, lack of adequate space and resources and gender discrimination. Finally, it concludes with a reflection on the most appropriate forms of dance in the educational context.
Modeling the Behavior of an Underwater Acoustic Relative Positioning System Based on Complementary Set of Sequences

Sensors , 2011, DOI: 10.3390/s111211188
Abstract: The great variability usually found in underwater media makes modeling a challenging task, but helpful for better understanding or predicting the performance of future deployed systems. In this work, an underwater acoustic propagation model is presented. This model obtains the multipath structure by means of the ray tracing technique. Using this model, the behavior of a relative positioning system is presented. One of the main advantages of relative positioning systems is that only the distances between all the buoys are needed to obtain their positions. In order to obtain the distances, the propagation times of acoustic signals coded by Complementary Set of Sequences (CSS) are used. In this case, the arrival instants are obtained by means of correlation processes. The distances are then used to obtain the position of the buoys by means of the Multidimensional Scaling Technique (MDS). As an early example of an application using this relative positioning system, a tracking of the position of the buoys at different times is performed. With this tracking, the surface current of a particular region could be studied. The performance of the system is evaluated in terms of the distance from the real position to the estimated one.

Abstract: In this article, a time-of-flight detection technique in the frequency domain is described for an ultrasonic Local Positioning System (LPS) based on encoded beacons. Beacon transmissions have been synchronized and become simultaneous by means of the DS-CDMA (Direct-Sequence Code Division Multiple Access) technique. Every beacon has been associated to a 255-bit Kasami code. The detection of signal arrival instant at the receiver, from which the distance to each beacon can be obtained, is based on the application of the Generalized Cross-Correlation (GCC), by using the cross-spectral density between the received signal and the sequence to be detected. Prior filtering to enhance the frequency components around the carrier frequency (40 kHz) has improved estimations when obtaining the correlation function maximum, which implies an improvement in distance measurement precision. Positioning has been achieved by using hyperbolic trilateration, based on the Time Differences of Arrival (TDOA) between a reference beacon and the others.
