Why do they separate it or not? Attitudes and behaviors towards organic waste separation

This article shows the results of an exploratory study related to the separation of organic waste in order to offer suggestions for the improvement of waste disposal communication campaigns. The overall objective is to analyze attitude and behavior of those who do and those who do not separate organic waste, related to a specific promotional campaign carried out in two neighborhoods, in the municipality of Badalona (Spain), within the framework of the study of proenvironmental attitudes and behaviors and based on the Psychosocial Four Spheres Model. 1,010 interviews were conducted and data was analyzed using Chi-Squared Automatic Interaction Detector (CHAID). Waste separation behavior was used as a dependent variable. The reasons given to explain why people do or do not separate organic waste and sociodemographic variables, have been introduced as independent variables. In accordance with the Four Spheres Model, results show significant differences in waste separation. Based on the profiles obtained, we find some predictive variables that facilitate the development of communication campaigns according to the requirements of each community.

In & Out – 180 habitatges per a gent jove i gent gran Camí Antic de València al Poblenou

Estratègies d’ordenació: L’ordenació proposada vol recollir la hibridesa i complexitat d’espais típica del Poble Nou. Caracteritzat pels espais lliures de mida intermèdia –a cavall entre els dels teixits i els del eixamples – i per la riquesa en les seves articulacions (mitjançant passatges, a través d’edificis,…) ; per la permeabilitat cap a l’interior de l’illa: la connexió dels buits interiors amb els carrers i espais públics annexes o per la variabilitat del gra edificat.És per això que l’edificació no s’entén com una sèrie de blocs aïllats sinó que està concebuda com una gran peça articulada, amb una alçada constant en el volum a carrer i una lleugera variabilitat volumètrica en altura en els diferents volums interiors de igual mòdul i de gra menor, homòleg al del seu context urbà més pròxim.És essencial al projecte la definició de l’espai buit interior de l’illa en relació als habitatges, i la seva relació –a una escala major- amb els espais lliures de l’entorn. L’ordenació proposada configura dos paisatges diferents: un pati més urbà, delimitat en planta baixa per un equipament del barri i al que s’hi aboquen els habitatges per a joves i un altre més tranquil i més tou, un jardí per als més grans, accessible des del carrer i des de l’espai públic contiguEl volum més llarg afegeix una nova inflexió a les que ja té el carrer, ampliant-lo amb un espai amb funció de vestíbul i recuperant així, a partir d’una traça parcel•laria històrica, la direcció de l’Eixample.Els diferents volums es relacionen/articulen mitjançant corredors i espais col•lectius de distintes mesures i qualitats. Espais de relació, de dimensió variable, en diferents situacions relatives –respecte al ple, al sòl- i amb distints caràcters, que van del privat al públic...passant pel col•lectiu.Les galeries i els corredors d'accés als habitatges, protagonistes d'aquests espais híbrids (privats-semiprivats-col•lectius/ interiors-exteriors/ tancats-oberts), es converteixen gràcies a la flexibilitat en el tancament de la unitat d'habitació en espais d'intercanvi, on la variabilitat en l'ús permet diferents apropiacions de l'espai col•lectiu.La superposició en altura d'aquests espais funciona com una estructura lleugera adossada a la façana, és una epidermis complexa amb aparença de bastida.L’edificació té la voluntat de tancar-se a carrer amb una façana poc perforada, que llisca indiferent al carrer, i d’obrir-se a l’interior de l’illa, a sud, on es torna complexa, amb successives pells i tamisos...

Análisis de la eficacia de los saques de esquina en la copa del mundo de fútbol 2010. Un intento de identificación de variables explicativas

In soccer, dead-ball moves are those in which the ball is returned to play from a stationary position following an interruption of play. The aim of this study was to analyse the effectiveness of one such dead-ball move, namely corner kicks, and to identify the key variables that determine the success of a shot or header following a corner, thereby enabling a model of successful corner kicks to be proposed. We recorded 554 corner kicks performed during the 2010 World Cup in South Africa and carried out a univariate, bivariate and multivariate analysis of the data. The results indicated that corners were of limited effectiveness in terms of the success of subsequent shots or headers. The analysis also revealed a series of variables that were significantly related to one another, and this enabled us to propose an explanatory model. Although this model had limited explanatory power, it nonetheless helps to understand the execution of corner kicks in practical terms.

Redefining dropping out in online higher education: a case study from the UOC

In recent years, studies into the reasons for dropping out of higher education (including online education) have been undertaken with greater regularity, parallel to the rise in the relative weight of this type of education, compared with brick-and-mortar education. However, the work invested in characterising the students who drop out of education, compared with those who do not, appears not to have had the same relevance as that invested in the analysis of the causes. The definition of dropping out is very sensitive to the context. In this article, we reach a purely empirical definition of student dropping out, based on the probability of not continuing a specific academic programme following several consecutive semesters of "theoretical break". Dropping out should be properly defined before analysing its causes, as well as comparing the drop-out rates between the different online programmes, or between online and on-campus ones. Our results show that there are significant differences among programmes, depending on their theoretical extension, but not their domain of knowledge.

Assigning and combining probabilities in single-case studies

There is currently a considerable diversity of quantitative measures available for summarizing the results in single-case studies. Given that the interpretation of some of them is difficult due to the lack of established benchmarks, the current paper proposes an approach for obtaining further numerical evidence on the importance of the results, complementing the substantive criteria, visual analysis, and primary summary measures. This additional evidence consists of obtaining the statistical significance of the outcome when referred to the corresponding sampling distribution. This sampling distribution is formed by the values of the outcomes (expressed as data nonoverlap, R-squared, etc.) in case the intervention is ineffective. The approach proposed here is intended to offer the outcome"s probability of being as extreme when there is no treatment effect without the need for some assumptions that cannot be checked with guarantees. Following this approach, researchers would compare their outcomes to reference values rather than constructing the sampling distributions themselves. The integration of single-case studies is problematic, when different metrics are used across primary studies and not all raw data are available. Via the approach for assigning p values it is possible to combine the results of similar studies regardless of the primary effect size indicator. The alternatives for combining probabilities are discussed in the context of single-case studies pointing out two potentially useful methods one based on a weighted average and the other on the binomial test.

Validation study of the Spanish Version of the Work-Family Conflict Questionnaire (CCTF)

In this study, a brief Work-Family Conflict (WFC) Questionnaire in the Spanish language is proposed that takes into account the two directions commonly reported in the literature: work interference with family (WIF), and family interference with work (FIW). The results obtained through exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) with two independent samples, carried out for women and men, showed acceptable validity and reliability. A copy of the instrument in Spanish language is provided, together with the Amos 4 syntax to perform the factor invariance analysis for women and men. The suggested Work-Family Conflict Questionnaire (in Spanish, abbreviated as CCTF) may be useful in studies performed in the work setting, considering the special relevance of the concept in this line of research.

Necrosis del tomate: "torrao "o "cribado"

Desde la primavera de 2001, viene presentándose en España una nueva enfermedad conocida con el nombre de "torrao" o "cribado". Los síntomas que habitualmente presentan las plantas afectadas son una necrosis en la parte basal del foliolo que evoluciona a cribado, en los peciolos aparecen manchas longitudinales en ocasiones endurecidas que llegan a curvar los foliolos, y los frutos manifiestan manchas necróticas, deformaciones que finalmente lo rajan, quedando comercialmente inviables. Muestreos realizados desde su aparición han determinado la mayor incidencia de la enfermedad en la zona de Murcia, seguido de Canarias y en menor proporción Almería, y Alicante. Los resultados de los análisis realizados a las 369 muestras recogidas determinan que el 67% de las muestras analizadas eran positivas a Pepino mosaic virus (PepMV). En los ensayos de transmisión, únicamente mediante el injerto, se consiguió reproducir los síntomas de la enfermedad en dos casos, en el resto las plantas inoculadas e injertadas únicamente mostraban síntomas típicos de PepMV y los análisis realizados confirmaron este aspecto. A la vista de los resultados obtenidos, se diseñó un nuevo método de diagnóstico que ha permitido la caracterización del 89% de las muestras analizadas como aislado Chileno 2 de PepMV, recientemente publicado en el Gen Bank (Accesión number: DQ000985). De acuerdo con lo expuesto podría tratarse de uno de los agentes implicados en el desarrollo del síndrome junto con otros factores aún por determinar

L'ensenyament del concepte piagetià de conservació: una experiència docent

The present work is aimed at reporting an educational experience about the conservation of the substance and the cognitive theories of Jean Piaget & Lev S. Vygotsky. This activity was carried out with 1st course students in the practical classes of the subject called Psicologia de l"educació i del desenvolupament en l"edat escolar, within the Teacher Training studies of the University of Girona. This experience was inspired by a proposal of González, Fuentes, de la Morena and Barajas (1995), in which the students have to analyse, using the solid and liquid conservation tasks created by Piaget and his colleagues from the Genevan School, the transition from the preoperational to the operational thought in infants aged from 4 to 8. This proposal has been adapted in order to analyse not only the infants" level of cognitive development but also what they can learn with the help of another person. Consequently, the students have chosen, administered and evaluated the support given to the children. Additionally, the different strategies used by the students in order to promote the infants" comprehension of the conservation have been studied and classified, which has allowed the reflection about other possible methods to teach and to show how to teach this concept El present treball pretén explicar una experiència docent sobre la conservació de la substància i les teories cognitives de Jean Piaget i Lev S. Vygotsky, en el marc de les pràctiques de l"assignatura Psicologia de l"educació i del desenvolupament en l"edat escolar amb alumnes 1r curs de la Diplomatura de Magisteri de la Universitat de Girona. Aquesta experiència s"ha inspirat en una proposta de González, Fuentes, de la Morena i Barajas (1995), en la qual els alumnes han d"analitzar el pas del pensament preoperatori al pensament operatori en infants de 4 a 8 anys, a través de tasques de conservació de la substància sòlida i líquida, les quals ja foren utilitzades per Piaget i els seus col·laboradors de l"Escola de Ginebra. Aquesta proposta ha estat adaptada per tal d"intentar analitzar el nivell de desenvolupament cognitiu dels infants no només a partir del que aquests són capaços de comprendre per sí sols sinó també a través d"ajudes, les quals han estat escollides, administrades i valorades pels propis estudiants. En aquesta revisió de la pràctica, s"han volgut delimitar les diferents estratègies utilitzades pels estudiants per tal de promoure la comprensió de la conservació en els infants, fet que ha permès la reflexió sobre d"altres possibles formes d"ensenyar i ensenyar a ensenyar aquest concep

Forecasting a language shift based on cellular automata

Language extinction as a consequence of language shifts is a widespread social phenomenon that affects several million people all over the world today. An important task for social sciences research should therefore be to gain an understanding of language shifts, especially as a way of forecasting the extinction or survival of threatened languages, i.e., determining whether or not the subordinate language will survive in communities with a dominant and a subordinate language. In general, modeling is usually a very difficult task in the social sciences, particularly when it comes to forecasting the values of variables. However, the cellular automata theory can help us overcome this traditional difficulty. The purpose of this article is to investigate language shifts in the speech behavior of individuals using the methodology of the cellular automata theory. The findings on the dynamics of social impacts in the field of social psychology and the empirical data from language surveys on the use of Catalan in Valencia allowed us to define a cellular automaton and carry out a set of simulations using that automaton. The simulation results highlighted the key factors in the progression or reversal of a language shift and the use of these factors allowed us to forecast the future of a threatened language in a bilingual community.

Bystander responses to a violent incident in an immersive virtual environment

Under what conditions will a bystander intervene to try to stop a violent attack by one person on another? It is generally believed that the greater the size of the crowd of bystanders, the less the chance that any of them will intervene. A complementary model is that social identity is critical as an explanatory variable. For example, when the bystander shares common social identity with the victim the probability of intervention is enhanced, other things being equal. However, it is generally not possible to study such hypotheses experimentally for practical and ethical reasons. Here we show that an experiment that depicts a violent incident at life-size in immersive virtual reality lends support to the social identity explanation. 40 male supporters of Arsenal Football Club in England were recruited for a two-factor between-groups experiment: the victim was either an Arsenal supporter or not (in-group/out-group), and looked towards the participant for help or not during the confrontation. The response variables were the numbers of verbal and physical interventions by the participant during the violent argument. The number of physical interventions had a significantly greater mean in the ingroup condition compared to the out-group. The more that participants perceived that the Victim was looking to them for help the greater the number of interventions in the in-group but not in the out-group. These results are supported by standard statistical analysis of variance, with more detailed findings obtained by a symbolic regression procedure based on genetic programming. Verbal interventions made during their experience, and analysis of post-experiment interview data suggest that in-group members were more prone to confrontational intervention compared to the out-group who were more prone to make statements to try to diffuse the situation.

The Dialogic Turn in Educational Psychology

The increasing presence of and claim for dialogue in today"s society has already had an impact on the theory and practice of learning. Whereas in the past individual and cognitive elements were seen as crucial to learning, since about two decades ago, scientific literature indicates that culture, interaction and dialogue are the key factors. In addition, the research project of highest scientific rank and with most resources dedicated to the study of school education in the Framework Program of the European Union: INCLUD-ED shows that the practices of successful schools around Europe are in line with the dialogic approach to learning. This article presents the dialogic turn in educational psychology, consisting of moving from symbolic conceptions of mind and internalist perspectives that focus on mental schemata of previous knowledge, to theories that see intersubjectivity and communication as the primary factors in learning. The paper deepens on the second approach.

Singling out individual inventors from patent data

An increasing number of studies in recent years have sought to identify individual inventors from patent data. A variety of heuristics have been proposed for using the names and other information disclosed in patent documents to establish who is who in patents. This paper contributes to this literature by describing a methodology for identifying inventors using patents applied to the European Patent Office, EPO hereafter. As in much of this literature, we basically follow a threestep procedure : 1- the parsing stage, aimed at reducing the noise in the inventor’s name and other fields of the patent; 2- the matching stage, where name matching algorithms are used to group similar names; and 3- the filtering stage, where additional information and various scoring schemes are used to filter out these similarlynamed inventors. The paper presents the results obtained by using the algorithms with the set of European inventors applying to the EPO over a long period of time.
