The internet in young people's everyday life: listening to portuguese teens' voices

[Excerto] Children and young people today go about their lives in an increasingly mediatized fashion. Their daily lives are inhabited by a variety of media, ranging from the so-called new media to the more traditional ones, which have an impact on how they perceive, get to kno,v and represent the world, how they interact with others, how they build their identity, and how they study, have fun and organize their daily lives. The media ecosystem, namely the digit.:tl environments, opened up opportunities to communicate, participate, create and produce information. Apparently, children and young people now have more means and opportunities at their disposal to express and share their ideas, interests and opinions, but are they actually taking advantage of such potential? \'(that uses are they making of these means? Does the Internet, in fact, enable the younger generations to create a new communication culture of expression and participation (...)?

Percepción y uso de flora y fauna por parte de los pobladores del sistema Laguna Mar Chiquita - Bañados del Río Dulce y área de influencia: diagnóstico e implicaciones para la conservación. Perception and use of flora and fauna by people of the system "Laguna Mar Chiquita - Bañados del Río Dulce" and it influence area: diagnosis and conservation implications.

La percepción, consumo y manejo de recursos naturales forma parte del conocimiento tradicional de distintas poblaciones humanas e involucra diversidad de actividades (recolección de plantas, caza y pesca, etc). Entre los vegetales, el uso de plantas medicinales se destaca por su persistencia y ubicuidad. El recurso animal, a través de la caza y la pesca, es fundamental como fuente de alimento y empleo. El sistema Mar Chiquita-Bañados del Río Dulce se destaca por su biodiversidad y la existencia de prácticas tradicionales de uso. La presión por conversión de ambientes naturales a tierras dedicadas al cultivo es fuerte, afectando principalmente a los bosques autóctonos, y las especies animales que en él habitan. Además, la desaparición de ambientes naturales conlleva la pérdida de prácticas tradicionales de uso, con la consiguiente deculturación. El presente trabajo evaluará la percepción y utilización de recursos naturales por los pobladores del área de influencia de Bañados del Río Dulce y Laguna Mar Chiquita, centrándose en plantas medicinales, peces, aves y mamíferos, a la vez de indagar sobre la diversidad de percepciones y conductas de apropiación de los recursos, dado que en la región coexisten diferentes pautas socio-culturales de acuerdo al grupo de procedencia. Como metodología básica para la recolección de datos de percepción y uso se utilizarán encuestas semi-estructuradas. Sobre el origen étnico y lazos sociales se relevarán de fuentes escritas sobre procedencia, pautas de elección de pareja y formas de residencia. Los muestreos de fauna a campo se realizarán al azar estratificados en pastizal, bosque, y áreas relacionadas a humedales en busca de huellas, heces y señales de la presencia de especies animales focales, a la vez de prospección visual y auditiva. Los datos obtenidos acerca del conocimiento y uso del ambiente se presentarán y analizarán mediante técnicas específicas para análisis de datos antropológicos cualitativos y madiante ANOVA. Los datos sobre origen y lazos serán analizados según indicadores de endogamia geográfica e indicadores de endogamia reproductiva. Los datos de presencia de las especies se utilizarán para desarrollar modelos de distribución regional y de nicho ecológico. Se espera caracterizar en forma diferencial la percepción y uso del ambiente de acuerdo al origen o área de residencia, a la vez de generar mapas de distribución de especies focales. Asimismo, se propondrán acciones de conservación de la biodiversidad, tales como cartillas o talleres tendientes a reforzar y re-significar los conocimientos locales sobre el uso de flora y fauna.

The Irish pub as a third place : a sociological exploration of people, place and identity

There is considerable interest in alcohol in Irish society, yet minimal sociologcial understanding of its consumption, particularly of the sites where most drinking occurs: the country's 8750 pubs. Despite widespread public discussions on the role of the pub, there is scant social science evidence to better inform debate. Pubs are central to Irish community and are key sites of social interaction. American sociologist Ray Oldenburg has argued that "third places" (neither workplace nor home) are crucial to the maintenance of the community and the enhancement of social capital. According to Oldenburg, the role of the third place in the community is to provide continuity, regularity, a sense of place - all of which conceptually contribute to the construction of the self, the projection of the self within the public sphere, the distribution of social capital and the generation of a collective identity. The pub is the archetypal third place, but Oldenburg is concerned that modern pubs are less able to provide this vital function. Social scientists have suggested that community is in a state of fragmentation and decline due to changes in modes of social interaction and a decrease in shared spaces, resulting in a weakened connection to place. Community without propinquity has been characterised by social alienation, fragmentation and what Oldenburg refers to as the "problem of place" (13). Third places, and thus the Irish pub, have been particularly affected. In order to increase the sociological knowledge of the pub in Ireland, this project critically engages with the pub to assess the importance that public drinking houses have in the everyday. Moreover, this research sets out to investigate the people/place relationship using the pub as an investigative lens and examine the ways in which people shape place, place shapes people and how that relationship is implicated in the construction of irish identities. Furthermore, this is also an articulation of a cultural shift within Ireland and Irish places whose effects are deep and multi-layered. This project aims to explore the development of the contemporary geography of identity as the irish pub as a third place is transformed or disappears from the social landscape.

Polish immigrants in Ireland's black economy: a phenomenological investigation

The purpose of this thesis is to answer the research question ‗why do some Polish migrants engage in shadow employment in the Republic of Ireland?‘ The individual and group interviews, which were conducted in August 2011 with thirteen Polish migrants, living and working in Ireland, generated the answer to the research question. Interviewees‘ responses were analysed from the point of view of the literature that examines the various factors within the topics of migration and the black economy. The thesis begins with theoretical background information regarding the enlargement of the European Union and the economic situation of Poland and Ireland. Then migration theories are explained and Polish and Irish migration history is presented. Next, the issue of the black economy and shadow employment is developed with a focus on its presence in Poland and Ireland. The following section is dedicated to the research methodology that was adopted to ensure effective collection of the information. The issues of the qualitative and quantitative research, phenomenological approach to the research and interviews as data collection are raised in that section. The last part of the thesis is based on an analysis of the respondents‘ statements. It explores interviewees‘ experience of life and work in Ireland. The main part of that section develops the reasons why do Polish workers engage in shadow employment in the Republic of Ireland. Simultaneously, it provides the answers to the research question of this thesis.

Silent voices : the recreational needs of disabled young people : an emancipatory approach

The recreational needs of young people with.disabilities in Sligo county were examined using an emancipatory approach that provided an accurate reflection on the perspectives of the disabled young people. The aim of this study included a comparison of access to and attitudes towards leisure activities as between disabled and non-disabled young people in the Sligo area. The hypothesis set out by the researcher was the expectation that findings would include a degree of disadvantage in access and participation in leisure activities for young people with disabilities vis a vis their counterparts. The way in which this was tested was by focus groups and interviews. This hypothesis was adequately proven along with an in-depth range of recommendations for improvement that were made by participants. The study’s emancipatory research methods ensured that the voice of the participants was heard regarding their recreational needs and the disabling barriers that needed to be removed.

The diet of the black widow spider Latrodectus mirabilis (Theridiidae) in two cereal crops of central Argentina

The spider Latrodectus mirabilis (Holmberg, 1876) is commonly found in cereals crops of central Argentina. We studied its diet composition at the field and capture rate on leaf-cutting ants based on laboratory experiments. This study comprises the first approach that documents the diet of L. mirabilis in wheat and oat fields of central Argentina. We identified 1,004 prey items collected from its webs during the last phenological stages of both cereal crops. The prey composition was variable but the spiders prey mainly on ants (Formicidae, Hymenoptera), who represented more than 86% of the total. Meanwhile, in the capture rate experiences we registered a high proportion of ants captured by spiders at the beginning of experiences, capturing the half of the ants from total in the first four hours. Summarizing, we reported a polyphagous diet of this spider species in wheat and oat fields. Ants were the most important prey item of this spider, as found in other Latrodectus spiders around the world.

The black-white test score gap widens with age?

We re-examine the theoretical concept of a production function for cognitive achievement, and argue that an indirect production function that depends upon the variables that constrain parents' choices is both moretractable from an econometric point of view, and more interesting from an economic point of view than is a direct production function that depends upon a detailed list of direct inputs such as number of books in the household. We estimate flexible econometric models of indirect production functions for two achievement measures from the Woodcock-Johnson Revised battery, using data from two waves of the Child Development Supplement to the PSID. Elasticities of achievement measures with respect to family income and parents' educational levels are positive and significant. Gaps between scores of black and white children narrow or remain constant as children grow older, a result that differs from previous findings in the literature. The elasticities of achievement scores with respect to family income are substantially higher for children of black families, and there are some notable difference in elasticities with respect to parents' educational levels across blacks and whites.
