Italy's urban waste metabolism

The problem of waste management is causing growing concern due to increasing generation rates, the emissions into soil, water and air, the social conflicts derived from the election of disposal sites and the loss of resources and energy among others. In this work, an innovative methodology is used to enable a better understanding of the waste generation and management system in Italy. Two new waste indicators are built to complement the conventional indicators used by official statistics. Then a multi-scale analysis of the Density of Waste Disposed (DWD) is carried out to highlight the territorial diversity of waste performances and test its contribution to detect plausible risky areas. Starting from Italian regions, the scale down goes on to the provincial level and, only for the region of Campania, the municipal one. First, the analysis shows that the DWD is able to complement the information provided by the conventional waste indicators. Second, the analysis shows the limitations of using a unique institutional solution to waste management problems. In this sense the multi-scale analysis provides with a more realistic picture of Italian waste system than using a single scale.

Questioning the utility of RNA-DNA chimera in gene repair.

In principle, we should be glad that Eric Kmiec and his colleagues published in Science's STKE (1) a detailed experimental protocol of their gene repair method (2, 3). However, a careful reading of their contribution raises more doubts about the method. The research published in Science five years ago by Kmiec and his colleagues was said to demonstrate that chimeric RNA-DNA oligonucleotides could correct the mutation responsible for sickle cell anemia with 50% efficiency (4). Such a remarkable result prompted many laboratories to attempt to replicate the research or utilize the method on their own systems. However, if the method worked at all, which it rarely did, the achieved efficiency was usually lower by several orders of magnitude. Now, in the Science's STKE protocol, we are given crucial information about the method and why it is so important to utilize these expensive chimeric RNA-DNA constructs. In the introduction we are told that the RNA-DNA duplex is more stable than a DNA-DNA duplex and so extends the half-life of the complexes formed between the targeted DNA and the chimeric RNA-DNA oligonucleotides. This logical explanation, however, conflicts with the statement in the section entitled "Transfection with Oligonucleotides and Plasmid DNA" that Kmiec and colleagues have recently demonstrated that classical single-stranded DNA oligonucleotides with a few protective phosphothioate linkages have a "gene repair conversion frequency rivaling that of the RNA/DNA chimera". Indeed, the research cited for that result actually states that single-stranded DNA oligonucleotides are in fact several-fold more efficient (3.7-fold) than the RNA-DNA chimeric constructs (5). If that is the case, it raises the question of why Kmiec and colleagues emphasize the importance of the RNA in their original chimeric constructs. Their own new results show that modified single-stranded DNA oligonucleotides are more effective than the expensive RNA-DNA hybrids. Moreover, the current efficiency of the gene repair by RNA-DNA hybrids, according to Kmiec and colleagues in their recent paper is only 4×10-4 even after several hours of pre-selection permitting multiplification of bacterial cells with the corrected plasmid (5). This efficiency is much lower than the 50% value reported five years ago, but is assuredly much closer to the reality.

Les communautés bulu contre la plantation industrielle HEVECAM au Cameroun

In 1975 the Kribi region (Southern Cameroon) became host of the rubber plantation HEVECAM, the third largest employer in Cameroon. The establishment of the plantation has been preceded by the expropriation of customary land and by the destruction of the rainforest used by local populations. As a result, conflicts – mostly latent – pitting neighbouring Bulu communities against the plantation have occurred, especially during the last few years. Drawing on fieldwork data as well as on anthropological, economic and historical materials, I try to explore a new way of looking at such environmental conflicts by arguing that they reflect the struggle between two distinct institutional logics with different impacts on the environment, i.e. the logic of property versus the one of possession. In short, the logic of possession corresponds to a multi-functional community-based forest management, while the logic of property gave birth to the commercial monoculture model, the highest stage of the transformation of an ecosystem in order to match the requirements of property. It is argued that the conflict between the logic of possession and the logic of property is at the heart of many cases of “environmentalisms of the poor” that arise in reaction to “development”.

Conjugation by Mosquito Pathogenic Strains of Bacillus sphaericus

A mosquito pathogenic strain of Bacillus sphaericus carried out the conjugal transfer of plasmid pAMß1 to other strains of its own and two other serotypes. However, it was unable to conjugate with mosquito pathogens from three other serotypes, with B. sphaericus of other DNA homology groups or with three other species of Bacillus. Conjugation frequency was highest with a strain having an altered surface layer (S layer). Conjugal transfer of pAMß1 was not detected in mosquito larval cadavers. B. sphaericus 2362 was unable to mobilize pUB110 for transfer to strains that had served as recipients of pAMß1. These observations suggest that it is unlikely that genetically engineered B. sphaericus carrying a recombinant plasmid could pass that plasmid to other bacteria

Gender-role alternation in the simultaneously hermaphroditic freshwater snail Physa acuta: not with the same partner

In simultaneous hermaphrodites, gender conflicts that arise from two potential mates sharing the same gender preference may be solved through conditional reciprocity (or gamete trading). Conditional reciprocity had initially been considered widespread, but recent studies suggest that its real occurrence may have been overestimated, possibly because most mating observations have been performed on isolated pairs of individuals. Some resulting patterns (e. g., non-random alternation of sexual roles) were indeed compatible with conditional reciprocity but could also have stemmed from the two partners independently executing their own mating strategy and being experimentally enforced to do so with the same partner. Non-random alternation of gender roles was recently documented in the simultaneously hermaphroditic freshwater snail Physa acuta. To distinguish between conditional and unconditional gender alternations, we observed copulations of individually marked snails reared at three contrasted densities. We showed that density affected the overall frequency of copulations during the first 2 days of the experiment with high-density boxes showing more copulations than low density boxes, but it did not affect gender alternation patterns. A change in gender role was observed more often than expected by chance over two successive copulations by the same individual, confirming previous studies. However, gender switches did not preferentially occur with the same partner. We conclude that gender alternation is not due to conditional reciprocity in P. acuta. It may rather stem from each individual having a preference for gender alternation. We finally discuss the mechanisms and the potential extent of this unconditional reciprocity.

Des hommes en mouvement : vers une reconfiguration des modèles masculins? L'exemple de la Suisse

This project is a study of the men's movement in Switzerland, especially regarding organizations seeking to redefine male identity. So far, this topic has been understudied, in Switzerland. The few studies available on the subject mostly adopt a (pro)feminist perspective. Their main purpose is to criticize men's movement participants. What is more, scarce researches on this problem mostly conducted by members of the Swiss men's movement themselves are mainly descriptive and methodologically problematic. In this context, I initiated the first national and sociological study of the men's movement in Switzerland. My main goals are: firstly, to propose a typology of organizations forming the men's movement in Switzerland. Secondly, I develop a sociological analysis of this phenomenon, taking into account in this process especially the characteristics of the Swiss context. Consequently, I adopted a mixed method approach, which included two main research steps: Firstly, I defined a representative sample of men's movement organizations in Switzerland. Based on a content analysis of men's organizations' websites, I was able to distinguish three ideal-types: Radical Criticism of Masculinity, Criticism of Hegemonic Masculinity, Defense of Men and Traditional Masculinity. Based on these three concepts, I subsequently analyzed the discourse on masculinity amongst men's movement organizations. Secondly, I conducted a survey of men's movement participants. This survey was based on the results of the content analysis. In this particular stage, I mainly used factor analysis. My results show that it would be all too simplistic to characterize the men's movement, in Switzerland, as a criticism of women's emancipation. On the contrary, my analysis reveals a more complex picture: The two main factors, which influence the men's movement, in Switzerland, are the contemporary sociological context and the Swiss society's particular features. I find that male roles, on the one hand, depend very much on today's cultural shift from materialistic to self-expression values. On the other hand, male role models reflect a social adaptation process. Moreover, as a reaction to deep changes in contemporary family structures, I observe an individualization process, characterized by separation between parental and conjugal functions that greatly shapes male role models. - Cette thèse analyse le phénomène des hommes en mouvement, dans le contexte de la Suisse. Cet ensemble est formé d'organisations regroupant des hommes impliqués consciemment dans un processus d'actions et de réflexions sur l'identité masculine. La revue de la littérature révèle qu'en Suisse, le sujet des hommes en mouvement est très peu étudié. Jusqu'ici, les rares recherches s'y intéressant adoptent généralement une approche (pro)féministe, dont l'objectif est de dénoncer ce phénomène. En outre, de rares recherches, issues des acteurs mêmes de ce mouvement, proposent une vue descriptive de l'ensemble, mais souffrant de faiblesses méthodologiques. Par notre recherche, nous souhaitons contribuer à l'étude de ce sujet, en initiant la première étude d'envergure nationale portant sur les hommes en mouvement. L'objectif final est de déboucher sur une typologie des organisations réunissant les hommes en mouvement, puis sur une analyse de la spécificité de cet ensemble, dans le contexte suisse. Pour remplir ces objectifs, nous avons mis en place un dispositif de méthodes mixtes, en deux phases. Lors d'une première étape, nous avons sélectionné un échantillon représentatif de la diversité des organisations masculines. Par une analyse de contenu effectuée sur la documentation récoltée sur les sites Internet de ces dernières, nous avons pu, en utilisant une démarche inductive et qualitative, faire émerger trois idéaux-types : Critique radicale de la masculinité, Critique de la masculinité hégémonique, Défense des hommes et de la masculinité traditionnelle. Ces concepts permettent de rendre compte, de manière schématique, des trois types de discours contemporains sur l'identité masculine diffusés par les hommes en mouvement. Lors d'une seconde étape, nous avons réalisé une enquête auprès des membres des organisations masculines. Pour y parvenir, nous avons créé un questionnaire incluant des propositions élaborées à partir des résultats de l'étape précédente. Lors de cette phase, nous avons réalisé une analyse factorielle. Les résultats montrent que le phénomène du mouvement des hommes ne saurait se réduire, en Suisse, à un mouvement de ressac visant à attaquer les droits des femmes. Au contraire, il s'agit d'un phénomène complexe, fortement dépendant du contexte sociologique contemporain et des caractéristiques de la société helvétique. Nous affirmons, entre autres, que les modèles masculins observables dans cet ensemble sont façonnés, d'une part, par une transition culturelle, caractérisée par le passage des valeurs matérialistes aux valeurs d'expression de soi. D'autre part, les modèles masculins prônés par les hommes en mouvement reflètent un processus d'adaptation sociale. En effet, en réaction au contexte de reconfiguration des formes familiales, on assiste à une individualisation des rapports de filiation et au détachement de la fonction parentale et conjugale, qui imprègnent fortement les modèles masculins défendus par ces hommes.

Análisis de la dimensión ambiental de la tenencia de la tierra. El caso de la Zona Protectora y Parque Nacional Volcán Tenorio de Costa Rica

El presente estudio consiste en la elaboración de un mapa del estado de tenencia de la tierra actual de la Zona Protectora y Parque Nacional Volcán Tenorio situado al norte de Costa Rica. A partir de este resultado cartográfico se efectuarán estudios referentes al estado legal de las propiedades, al tipo de propiedad, a la ubicación de las propiedades dentro del Área Silvestre Protegida y al evalúo de los conflictos legales dentro de ésta. Por otro lado, se analiza la cobertura de la tierra y el estado de conservación. La metodología utilizada se basa en el uso de Sistemas de Información Geográfica y en la verificación de la información mediante puntos GPS tomados al campo y su análisis en la oficina. Los resultados muestran una reubicación de los planos más precisa y real que la indicada por el Catastro Nacional. Aunque las propiedades privadas son mayoritarias, el área de estudio presenta en general un porcentaje alto de masa boscosa, mientras que en las zonas limítrofes se encuentra una fragmentación del hábitat determinada por herbazales. Este estudio contribuye a una mejor gestión y conservación del Área Protegida y es un avance en el ordenamiento territorial del país.

Multisensory mechanisms in temporo-parietal cortex support self-location and first-person perspective.

Self-consciousness has mostly been approached by philosophical enquiry and not by empirical neuroscientific study, leading to an overabundance of diverging theories and an absence of data-driven theories. Using robotic technology, we achieved specific bodily conflicts and induced predictable changes in a fundamental aspect of self-consciousness by altering where healthy subjects experienced themselves to be (self-location). Functional magnetic resonance imaging revealed that temporo-parietal junction (TPJ) activity reflected experimental changes in self-location that also depended on the first-person perspective due to visuo-tactile and visuo-vestibular conflicts. Moreover, in a large lesion analysis study of neurological patients with a well-defined state of abnormal self-location, brain damage was also localized at TPJ, providing causal evidence that TPJ encodes self-location. Our findings reveal that multisensory integration at the TPJ reflects one of the most fundamental subjective feelings of humans: the feeling of being an entity localized at a position in space and perceiving the world from this position and perspective.

Law and the practise of principle in diverse societies

Projecte de recerca elaborat a partir d’una estada a la London School of Economics and Political Science, United Kingdom, entre 2007 i 2009. L’objecte principal del projecte ha estat analitzar les implicacions jurídico-polítiques i institucionals d’una teoria de la justícia i la igualtat liberals aplicada a societats multiculturals amb un marcat predomini de la diversitat cultural. L’anàlisi desenvolupa una línia d'investigació interdisciplinar - entre el dret i la teoria política - iniciada en una tesis doctoral sobre multiculturalisme i drets de les minories culturals (UPF, 2000) que va culminar en la publicació de Group Rights as Human Rights (Springer, 2006). La recerca adopta com a punt de partida les conclusions de l'esmentada obra, en especial, la rellevància del reconeixement de drets col•lectius; tanmateix, el tipus de qüestions plantejades, l’enfoc i la metodologia emprades són substancialment diferents. En concret, s'adrecen preguntes específiques sobre el model i aspiracions del constitucionalisme democràtic i el paper del dret en contextos multiculturals. També s’atorga un pes central a la dimensió institucional dels models de gestió de la diversitat que s’analitzen, prioritzant un enfocament comparatiu a partir de l’estudi de controvèrsies concretes. L’objectiu és superar algunes limitacions importants de la literatura actual, com ara la tendència a examinar en abstracte la compatibilitat de determinades demandes amb el constitucionalisme democràtic, sense abordar el funcionament d'estratègies de gestió de la diversitat cultural emprades en contextos concrets. Els treballs producte d'aquest projecte articulen les línies bàsiques d’un model pluralista, basat en principis més que en regles, que desafia els plantejaments dominants actualment. Aquest model es caracteritza pel compromís amb la legitimitat i igualtat comparatives, rebutjant el paternalisme i les visions liberals típiques sobre el paper de la regulació. La presumpció de l’“standing” moral dels grups identitaris és fonamental per tal de considerar-los interlocutors vàlids amb interessos genuïns. També s’argumenta que la integració social en contextos multiculturals no depèn tant de l’eliminació del conflicte sinó, sobre tot, d’una gestió eficient que eviti abusos de poder sistemàtics. El model defensa el rol del dret en la institucionalització del diàleg intercultural, però admet que el diàleg no necessàriament condueix a l’acord o a una estructura reguladora coherent i uniforme. Les aspiracions del ordre jurídic pluralista són més modestes: afavorir la negociació i resolució en cada conflicte, malgrat la persistència de la fragmentació i la provisionalitat dels acords. La manca d'un marc regulador comú esdevé una virtut en la mesura que permet la interacció de diferents subordres; una interacció governada per una multiplicitat de regles no necessàriament harmòniques. Els avantatges i problemes d’aquest model s'analitzen a partir de l'anàlisi de l’estructura fragmentària de l'ordre jurídic internacional i del règim Europeu de drets humans.

Non-nest mate discrimination and clonal colony structure in the parthenogenetic ant Cerapachys biroi

Understanding the interplay between cooperation and conflict in social groups is a major goal of biology. One important factor is genetic relatedness, and animal societies are usually composed of related but genetically different individuals, setting the stage for conflicts over reproductive allocation. Recently, however, it has been found that several ant species reproduce predominantly asexually. Although this can potentially give rise to clonal societies, in the few well-studied cases, colonies are often chimeric assemblies of different genotypes, due to worker drifting or colony fusion. In the ant Cerapachys biroi, queens are absent and all individuals reproduce via thelytokous parthenogenesis, making this species an ideal study system of asexual reproduction and its consequences for social dynamics. Here, we show that colonies in our study population on Okinawa, Japan, recognize and effectively discriminate against foreign workers, especially those from unrelated asexual lineages. In accord with this finding, colonies never contained more than a single asexual lineage and average pairwise genetic relatedness within colonies was extremely high (r = 0.99). This implies that the scope for social conflict in C. biroi is limited, with unusually high potential for cooperation and altruism.

Crisis matrimoniales y su prevención

Les crisis sobrevenen en tota unió matrimonial. És necessari diferenciar entre crisis funcionals o fisiològiques i crisi patològiques. Les primeres son pròpies de la vida conjugal i es produiran a qualsevol matrimoni, formant part de la seva evolució madurativa, i les segones només tindran lloc en alguns matrimonis causant problemes més greus. Ambdues crisis requereixen d’estratègies de resolució de problemes, perquè el cònjuges puguin superar-les conjuntament, encara que en las segones habitualment es necessari d’intervenció terapèutica per poder-les superar. A través d’aquest treball es pretén explicar les crisis matrimonials i la seva prevenció.

Conflictes i articulacions entre el dret local i el dret estatal a Madagascar

Aquesta recerca analitza els conflictes i les articulacions entre el dret local i el dret estatal que tenen lloc a les comunitats rurals de Madagascar a l’hora de resoldre els conflictes a l’àmbit local. L’anàlisi es porta a terme a partir d’un cas etnogràfic concret que permet descriure aquesta pluralitat jurídica. A la present memòria es descriu el treball realitzat en el recorregut de la investigació i dóna compte de la gestació del projecte fins a l’actualitat, moment en el qual la recerca es troba en el seu darrer punt de redacció de la tesi.

Eusociality and cooperation

The evolution of eusociality, here defined as the emergence of societies with reproductive division of labour and cooperative brood care, was first seen as a challenge to Darwin's theory of evolution by natural selection. Why should individuals permanently forgo direct reproduction to help other individuals to reproduce? Kin selection, the indirect transmission of genes through relatives, is the key process explaining the evolution of permanently nonreproductive helpers. However, in some taxa helpers delay reproduction until a breeding opportunity becomes available. Overall, eusociality evolved when ecological conditions promote stable associations of related individuals that benefit from jointly exploiting and defending common resources. High levels of cooperation and robust mechanisms of division of labour are found in many animal societies. However, conflicts among individuals are still frequent when group members that are not genetically identical compete over reproduction or resource allocation.

Purine transport and the cell cycle.

Background: Alliance evolutions, i.e. ruptures and resolutions over the course of psychotherapy, have been shown to be important descriptive features in different forms of psychotherapy, and in particular in psychodynamic psychotherapy. This case study of a client presenting elements of adjustment disorder undergoing short-term dynamic psychotherapy is drawn from a systematic naturalistic study and aims at illustrating, on a session-by-session-level, the processes of alliance ruptures and resolutions, by comparing both the client's and the therapist's perspectives. Method: Two episodes of alliance evolution were more fully studied, in relation to the evolution of transference, as well as the client's defensive functioning and core conflictual theme. These concepts were measured by means of valid, reliable observer-rater methods, based on session transcripts: the Defense Mechanisms Rating Scales (DMRS) for defensive functioning and the Core Conflictual Relationship Theme (CCRT) for the conflicts. Alliance was measured after each session using the Helping Alliance questionnaire (HAq-II). Results: The results indicated that these episodes of alliance rupture and resolutions may be understood as key moments of the whole therapeutic process reflecting the client's main relationship stakes. Illustrations are provided based on the client's in-session processes and related to the alliance development over the course of the entire therapy.

New developments of peace research: The impact of recent campaigns on disarmament and human security

The present text, based on previous work done by the authors on peace research (Grasa 1990 and 2010) and the disarmament campaigns linked to Human Security (Alcalde 2009 and 2010), has two objectives. First, to present a new agenda for peace research, based on the resolution/transformation of conflicts and the promotion of collective action in furtherance of human security and human development. Second, to focus specifically on collective action and on a positive reading of some of the campaigns that have taken place during the last decades in order to see how the experiences of such will affect the future agenda for peace research and action for peace.
