New opportunities for farm accounting

There is a gap between the importance given to accounting and the low level of bookkeeping and accounting practice in the agricultural sector. Current general accounting rules do not adapt very well to the particularities of farming and are difficult and expensive to implement. The Farm Accountancy Data Network (FADN) and IASC's Proposed International Accounting Standard on Agriculture (PIASA) could be key elements to improve the use of accounting in European farms. The PIASA provides a strong conceptual framework but might need further instruments for its implementation in practice. FADN is an experienced network that has elaborated very detailed farm accounting procedures. Empirical data indicate that current FADN reports are already considered useful by farmers for different purposes. Some changes in the FADN procedures are suggested, while some aspects of FADN are worthwhile for the future IAS on agriculture.

Una infraestructura de metadades bibliogràfiques pel segle XXI

Aquest article tracta l'actual infraestructura bibliogràfica de les biblioteques que va ser creada en els inicis dels ordinadors – abans de la Web, XML, i de la varietat d'altres avenços tecnològics que en l'actualitat ofereixen noves oportunitats. Per una banda, s'identifiquen els requisits generals d'una infraestructura de metadades moderna per a les biblioteques incloent qualitats com: versatilitat, extensibilitat, granularitat i accessibilitat. Per l'altra banda, es proposa un nou tipus d'infraestructura de metadades que mostra, com a mínim, alguna d'aquestes qualitats. S'han identificat alguns temes clau que caldrà superar per tal d'implementar un canvi d'aquesta magnitud.

Government and the distribution of skills

Individuals' life chances in the future will very much depend on how we invest in our children now. An optimal human capital model would combine a high mean with minimal variance of skills. It is well-established that early childhood learning is key to adult success. The impact of social origins on child outcomes remains strong, and the new role of women poses additional challenges to our conventional nurturing approach to child development. This paper focuses on skill development in the early years, examining how we might best combine family inputs and public policy to invest optimally in our future human capital. I emphasize three issues: one, the uneven capacity of parents to invest in children; two, the impact of mothers' employment on child outcomes; and three, the potential benefits of early pre-school programmes. I conclude that mothers' intra-family bargaining power is decisive for family investments and that universal child care is key if our goal is to arrive at a strong mean with minimal variance.

Calidad de vida y percepción de la desigualdad de la mujer en la ciudad de Girona = Quality of life and inequality perception’s of women in the city of Girona

La igualdad de oportunidades para las mujeres, como factor clave para avanzar en la consecución de calidad de vida preocupa hoy en día a la sociedad en general y alas instituciones en particular. Antes de la elaboración de programas de intervención social es necesario conocer las percepciones de las propias mujeres acerca de sus problemas y de sus necesidades. Siguiendo esta línea de pensamiento presentamos un trabajo empírico en el que analizamos las percepciones de las mujeres de la ciudad de Girona, centrándonos en dos aspectos de manera particular: la percepción de calidad de vida proporcionada por su ciudad y la percepción de desigualdad de oportunidades y/o de discriminación. Los principales resultados, obtenidos a partir de las respuestas a un cuestionario auto-administrado, y proporcionados por una muestra de mujeres seleccionadas aleatoriamente a partir de un muestreo estratificado geográficamente, indican que en general están satisfechas con su ciudad aunque detectamos las principales causas de insatisfacción. Por otra parte, tas principales fuentes de desigualdad se refieren al mundo laboral (menos salario por el mismo trabajo, dificultades de encontrar trabajo si tienen hijos o si son ya mayores), y en la actitud general de la sociedad en el sentido de tener que cumplir el papel que tradicionalmente se les ha asignado

Probiotic microorganisms: 100 years of innovation and efficacy. Modes of action

AbstractArticle StructureFigures and TablesReferences Benefits from probiotic micro-organisms have been recognised for over 100 years, and as being useful in poultry for 50 years. Fuller (1989) redefined probiotics as ‘a live microbial feed supplement which beneficially affects the host animal by improving its intestinal microbial balance’. Benefits derived from this improved intestinal microbial balance could be reflected in performance or prevention of pathogen colonisation. Probiotic micro-organisms use in poultry production has been widely accepted and new opportunities arose from the 2006 EU ban on antimicrobial growth promoters. The majority of microbial products for compound feeds are made up from a relatively small number of micro-organisms that are normally present in the GI tract. They include non-sporulated bacteria, sporulated bacteria, fungi or yeasts; and presented from single to multi-strain products. A review on the proposed modes of action is presented including recent approaches to quorum sensing interference

Children's work in Spanish textiles during the 19th and 20th Centuries

This essay deals with the reasons explaining children s work in 19th century textile factories and their removal during the first part of the 20th century. The inadequacy of the structure of incomes and expenditures of the household and the very low economic incentives to educate children can explain why children were in the factories and not in the school. Moreover, the marginal economic contribution to the economy of the household of a child was the same as that of his mother. This normally implied that women and children were perfect substitutes. When the family had a child at working age this allowed to replace the paid work input of the mother. With the beginnings of the 20th century a set of changes leading to the increase of women s productivity and hourly real wages, switched the situation and involved the new incorporation of women into paid work and the investment in children s human capital.

Panoràmica dels sistemes de gestió de biblioteques al segle XXI

In the past decade, a number of trends have come together in the general sphere of computing that have profoundly affected libraries. The popularisation of the Internet, the appearance of open and interoperable systems, the improvements within graphics and multimedia, and the generalised installation of LANs are some of the events of the period. Taken together, the result has been that libraries have undergone an important functional change, representing the switch from simple information depositories to information disseminators. Integrated library management systems have not remained unaffected by this transformation and those that have not adapted to the new technological surroundings are now referred to as legacy systems. The article describes the characteristics of systems existing in today's market and outlines future trends that, according to various authors, include the disappearance of the integrated library management systems that have traditionally been sold.

Elements apresos i/o retinguts per infants de dos centres de contextos diferents a partir d'una comunicació generada entre ells amb les TIC

La comunicació com a mètode per aprendre no és nou, tot i així les noves tecnologies obren la porta a noves oportunitats i nous projectes entorn aquest concepte. No només es tracta de treballar elements curriculars, sinó també actitudinals a través de la opció de connexió entre contextos. L’objectiu d’aquesta recerca és analitzar quina és l’actitud i els aprenentatges i/o retencions dels infants a partir d’una connexió generada entre dos contextos. Per tal de donar resposta a aquest plantejament de la investigació es crea una intervenció entre les aules i s’utilitzen com a instruments de recollida de dades les observacions, els dibuixos i els grups de discussió. Els resultats mostren una actitud oberta i d’interès per part dels infants davant de la metodologia de comunicació a l’aula, però un aprenentatge i/o retenció relacionat amb els continguts dels elements de l’altre context per sobre dels elements TIC. Es conclou doncs que dins l’aula treballant amb les noves tecnologies es genera un incentiu pels infants fent evident que hi ha hagut un aprenentatge compartit.

Understanding oceanic migrations with intrinsic biogeochemical markers

Migratory marine vertebrates move annually across remote oceanic water masses crossing international borders. Many anthropogenic threats such as overfishing, bycatch, pollution or global warming put millions of marine migrants at risk especially during their long-distance movements. Therefore, precise knowledge about these migratory movements to understand where and when these animals are more exposed to human impacts is vital for addressing marine conservation issues. Because electronic tracking devices suffer from several constraints, mainly logistical and financial, there is emerging interest in finding appropriate intrinsic markers, such as the chemical composition of inert tissues, to study long-distance migrations and identify wintering sites. Here, using tracked pelagic seabirds and some of their own feathers which were known to be grown at different places and times within the annual cycle, we proved the value of biogeochemical analyses of inert tissue as tracers of marine movements and habitat use. Analyses of feathers grown in summer showed that both stable isotope signatures and element concentrations can signal the origin of breeding birds feeding in distinct water masses. However, only stable isotopes signalled water masses used during winter because elements mainly accumulated during the long breeding period are incorporated into feathers grown in both summer and winter. Our findings shed new light on the simple and effective assignment of marine organisms to distinct oceanic areas, providing new opportunities to study unknown migration patterns of secretive species, including in relation to human-induced mortality on specific populations in the marine environment.

La adolescencia: retos para la investigación y para la sociedad europea de cara al sigol XXI

A lo largo de la última década, la adolescencia ha sido un tema dediscusión política en distintos espacios europeos al más alto nivel. En unasociedad aceleradamente cambiante se percibe que la adecuada socializaciónde las generaciones más jóvenes constituye un reto socio-históricoque nos afecta a todos. Los cambios en que estamos sumergidos son tanplurales (demográficos, sociales, tecnológicos, económicos, políticos,etc.) que generan un amplísimo frente de nuevos dilemas éticos. La opiniónde los ciudadanos de la Unión Europea se muestra preocupada pornuevos valores y destaca la preferencia por la responsabilidad en coherenciacon dicha situación cambiante. Todo este macrocontexto psicosocialviene planteando nuevos retos teóricos y de investigación a la comunidadcientífica. De hecho las ciencias humanas y sociales han empezadoa desarrollar nuevas líneas de investigación para comprender mejor lasnuevas relaciones entre adultos y adolescentes y las nuevas culturas queemergen entre estos últimos, impulsadas por nuevas aspiraciones socialescompartidas por grupos más o menos amplios de la población joven. Eldesarrollo de técnicas e instrumentos que nos permitan comprender mejorla perspectiva del adolescente se hace más evidente si analizamos su relacióncon las nuevas tecnologías de la información y la comunicación. Dichastecnologías comportan nuevos riesgos, pero también nuevas oportunidades,entre las que destaca la posibilidad de establecer nuevas formasde relación. La motivación que muestran los más jóvenes por las nuevastecnologías constituye un gran reto a los investigadores aplicados parasugerir formas de maximizar las potencialidades latentes

1st National Accessiblity Plan 2004-2012: achieving equal opportunities and full participation through design for all

According to official statistics, disabled people in Spain number 3.5 million and make up 8.8% of the Spanish population. This group of people are increasingly being recognised as members of society with equal rights, and many of their demands are gradually being transformed into solutions that benefit society as a whole. One example is improved accessibility. Accessible built environments are more human and inclusive places, as well as being easier to get around. Improved accessibility is now recognised as a requirement shared by all members of society, although it is achieved thanks to the demands of disabled people and their representatives. The 1st National Accessibility Plan is a strategic framework for action aimed at ensuring that new products, services and built environments are designed to be accessible for as many people as possible (Design for All) and that existing ones are gradually duly adapted.

A Reply to comments by D. Bar-Yosef M. Stiner on "Prehistoric exploitation of marine resources in Southern Africa with particular reference to shellfish gathering: opportunities and continuities"

I am very grateful to Daniella E. Bar-Yosef Mayer and Mary Stiner for their comments on an article I published in the previous issue of Pyrenae. Having spent many years working with coastal sites in South Africa and now settling in the Mediterranean academic landscape, I value the feedback from these two well-known archaeologists who have dedicated years of hard work in this later part of the world. Their opinions are very much appreciated for they allow me to bring new contexts to some of the (old) questions I have pursued in South Africa, an exercise that would help me with the process of broadening my research interests to the Mediterranean region.
