Monitoring and enforcement are perhaps the biggest challenges in the design and implementation of environmental policies in developing countries where the actions of many small informal actors cause significant impacts on the ecosystem services and where the transaction costs for the state to regulate them could be enormous. This dissertation studies the potential of innovative institutions based on decentralized coordination and enforcement to induce better environmental outcomes. Such policies have in common that the state plays the role of providing the incentives for organization but the process of compliance happens through decentralized agreements, trust building, signaling and monitoring. I draw from the literatures in collective action, common-pool resources, game-theory and non-point source pollution to develop the instruments proposed here. To test the different conditions in which such policies could be implemented I designed two field-experiments that I conducted with small-scale gold miners in the Colombian Pacific and with users and providers of ecosystem services in the states of Veracruz, Quintana Roo and Yucatan in Mexico. This dissertation is organized in three essays.

The first essay, “Collective Incentives for Cleaner Small-Scale Gold Mining on the Frontier: Experimental Tests of Compliance with Group Incentives given Limited State Monitoring”, examines whether collective incentives, i.e. incentives provided to a group conditional on collective compliance, could “outsource” the required local monitoring, i.e. induce group interactions that extend the reach of the state that can observe only aggregate consequences in the context of small-scale gold mining. I employed a framed field-lab experiment in which the miners make decisions regarding mining intensity. The state sets a collective target for an environmental outcome, verifies compliance and provides a group reward for compliance which is split equally among members. Since the target set by the state transforms the situation into a coordination game, outcomes depend on expectations of what others will do. I conducted this experiment with 640 participants in a mining region of the Colombian Pacific and I examine different levels of policy severity and their ordering. The findings of the experiment suggest that such instruments can induce compliance but this regulation involves tradeoffs. For most severe targets – with rewards just above costs – raise gains if successful but can collapse rapidly and completely. In terms of group interactions, better outcomes are found when severity initially is lower suggesting learning.

The second essay, “Collective Compliance can be Efficient and Inequitable: Impacts of Leaders among Small-Scale Gold Miners in Colombia”, explores the channels through which communication help groups to coordinate in presence of collective incentives and whether the reached solutions are equitable or not. Also in the context of small-scale gold mining in the Colombian Pacific, I test the effect of communication in compliance with a collective environmental target. The results suggest that communication, as expected, helps to solve coordination challenges but still some groups reach agreements involving unequal outcomes. By examining the agreements that took place in each group, I observe that the main coordination mechanism was the presence of leaders that help other group members to clarify the situation. Interestingly, leaders not only helped groups to reach efficiency but also played a key role in equity by defining how the costs of compliance would be distributed among group members.

The third essay, “Creating Local PES Institutions and Increasing Impacts of PES in Mexico: A real-Time Watershed-Level Framed Field Experiment on Coordination and Conditionality”, considers the creation of a local payments for ecosystem services (PES) mechanism as an assurance game that requires the coordination between two groups of participants: upstream and downstream. Based on this assurance interaction, I explore the effect of allowing peer-sanctions on upstream behavior in the functioning of the mechanism. This field-lab experiment was implemented in three real cases of the Mexican Fondos Concurrentes (matching funds) program in the states of Veracruz, Quintana Roo and Yucatan, where 240 real users and 240 real providers of hydrological services were recruited and interacted with each other in real time. The experimental results suggest that initial trust-game behaviors align with participants’ perceptions and predicts baseline giving in assurance game. For upstream providers, i.e. those who get sanctioned, the threat and the use of sanctions increase contributions. Downstream users contribute less when offered the option to sanction – as if that option signal an uncooperative upstream – then the contributions rise in line with the complementarity in payments of the assurance game.

BACKGROUND: The neonatal and pediatric antimicrobial point prevalence survey (PPS) of the Antibiotic Resistance and Prescribing in European Children project (http://www.arpecproject.eu/) aims to standardize a method for surveillance of antimicrobial use in children and neonates admitted to the hospital within Europe. This article describes the audit criteria used and reports overall country-specific proportions of antimicrobial use. An analytical review presents methodologies on antimicrobial use.

METHODS: A 1-day PPS on antimicrobial use in hospitalized children was organized in September 2011, using a previously validated and standardized method. The survey included all inpatient pediatric and neonatal beds and identified all children receiving an antimicrobial treatment on the day of survey. Mandatory data were age, gender, (birth) weight, underlying diagnosis, antimicrobial agent, dose and indication for treatment. Data were entered through a web-based system for data-entry and reporting, based on the WebPPS program developed for the European Surveillance of Antimicrobial Consumption project.

RESULTS: There were 2760 and 1565 pediatric versus 1154 and 589 neonatal inpatients reported among 50 European (n = 14 countries) and 23 non-European hospitals (n = 9 countries), respectively. Overall, antibiotic pediatric and neonatal use was significantly higher in non-European (43.8%; 95% confidence interval [CI]: 41.3-46.3% and 39.4%; 95% CI: 35.5-43.4%) compared with that in European hospitals (35.4; 95% CI: 33.6-37.2% and 21.8%; 95% CI: 19.4-24.2%). Proportions of antibiotic use were highest in hematology/oncology wards (61.3%; 95% CI: 56.2-66.4%) and pediatric intensive care units (55.8%; 95% CI: 50.3-61.3%).

CONCLUSIONS: An Antibiotic Resistance and Prescribing in European Children standardized web-based method for a 1-day PPS was successfully developed and conducted in 73 hospitals worldwide. It offers a simple, feasible and sustainable way of data collection that can be used globally.

Nursing publications frequently reference groups (e.g. the group nurses). The nature and capabilities of group agents or collective subjects, and the relationship between nursing as a group and nurses as individuals is, however, rarely made explicit in these publications. Following Alvin Goldman, questions pertaining to groups can be classified as metaphysical or epistemic. Metaphysical questions take two forms. First, we might ask about the ontological status of group agents. For example, to what extent, if at all, do group agents exist and act independently of their constituent members? Second, we can ask whether group agents have psychological states or properties that can, for example, be formulated as propositional attitudes and, if they can, in what ways are group attitudes correlated with or tied to those of individual group members? In this presentation, having recognised the potential reality of group ontological and psychological being, I examine an under researched element of social epistemology. Specifically, the potential of non-individualist reliabilism (social process reliabilism) to justify doxastic group beliefs (i.e. statements such as “nurses believe that”) are considered. It is suggested that this issue has concrete implications for how we think about nursing.

I wanted to explore whether traditional Forum Theatre approaches can be enhanced by the use of integrated voting software to empower young people. My research is based on two of a series of widening participation interactive TiE programmes focused on the decisions young people make on educational progression. I worked as a director alongside students studying Drama and Performance at The University of Worcester and the programmes have toured widely to schools across Worcestershire and Herefordshire. ‘It’s Up to You!’ (2013 – 2014) was aimed at years 8 and 9 choosing their GCSE options and ‘Move on Up!’ (2014 - 2015) looked at the hopes and fears of year 6 pupils about to go up to secondary school. Finding a voice in Boal’s framework as a ‘specactor’ does not always appeal to a pupil who does not want to stand out from the crowd or is not familiar with a classroom where drama conventions are practised or understood. The anonymity of the voting software with results of decisions made appearing instantly on screen is certainly appealing to some pupils: ‘I also loved the keypads they gave us so that we could answer the questions without having to put our hand up and wait..’ This paper aims to interrogate the idea that empowering needs to not simply be about giving voice to a few confident group members but allowing the silent majority to be able to experiment with decision making in an educational and social context.

The workshop took place on 16-17 January in Utrecht, with Seventy experts from eight European countries in attendance. The workshop was structured in six sessions: usage statistics research paper metadata exchanging information author identification Open Archives Initiative eTheses Following the workshop, the discussion groups were asked to continue their collaboration and to produce a report for circulation to all participants. The results can be downloaded below. The recommendations contained in the reports above have been reviewed by the Knowledge Exchange partner organisations and formed the basis for new proposals and the next steps in Knowledge Exchange work with institutional repositories. Institutional Repository Workshop - Next steps During April and May 2007 Knowledge Exchange had expert reviewers from the partner organisations go though the workshop strand reports and make their recommendations about the best way to move forward, to set priorities, and find possibilities for furthering the institutional repository cause. The KE partner representatives reviewed the reviews and consulted with their partner organisation management to get an indication of support and funding for the latest ideas and proposals, as follows: Pragmatic interoperability During a review meeting at JISC offices in London on 31 May, the expert reviewers and the KE partner representatives agreed that ‘pragmatic interoperability' is the primary area of interest. It was also agreed that the most relevant and beneficial choice for a Knowledge Exchange approach would be to aim for CRIS-OAR interoperability as a step towards integrated services. Within this context, interlinked joint projects could be undertaken by the partner organisations regarding the areas that most interested them. Interlinked projects The proposed Knowledge Exchange activities involve interlinked joint projects on metadata, persistent author identifiers, and eTheses which are intended to connect to and build on projects such as ISPI, Jisc NAMES and the Digital Author Identifier (DAI) developed by SURF. It is important to stress that the projects are not intended to overlap, but rather to supplement the DRIVER 2 (EU project) approaches. Focus on CRIS and OAR It is believed that the focus on practical interoperability between Current Research Information Systems and Open Access Repository systems will be of genuine benefit to research scientists, research administrators and librarian communities in the Knowledge Exchange countries; accommodating the specific needs of each group. Timing June 2007: Write the draft proposal by KE Working Group members July 2007: Final proposal to be sent to partner organisations by KE Group August 2007: Decision by Knowledge Exchange partner organisations.

In many vertebrate societies, forced eviction of group members is an important determinant of population structure, but little is known about what triggers eviction. Three main explanations are: (i) the reproductive competition hypothesis, (ii) the coercion of cooperation hypothesis, and (iii) the adaptive forced dispersal hypothesis. The last hypothesis proposes that dominant individuals use eviction as an adaptive strategy to propagate copies of their alleles through a highly structured population. We tested these hypotheses as explanations for eviction in cooperatively breeding banded mongooses (Mungos mungo), using a 16-year dataset on life history, behaviour and relatedness. In this species, groups of females, or mixed-sex groups, are periodically evicted en masse. Our evidence suggests that reproductive competition is the main ultimate trigger for eviction for both sexes. We find little evidence that mass eviction is used to coerce helping, or as a mechanism to force dispersal of relatives into the population. Eviction of females changes the landscape of reproductive competition for remaining males, which may explain why males are evicted alongside females. Our results show that the consequences of resolving within-group conflict resonate through groups and populations to affect population structure, with important implications for social evolution.

This research examined effects of individual self-presentation styles on influence in groups. Perceived competence and social acceptance both play a role in determining how much influence group members enjoy. Aggrandizing and deprecating self-presentation styles may affect perceived competence, social acceptance, and ultimately influence. I predicted that aggrandizing self-presentation would lead to perceptions of competence and that self-deprecation would lead to social acceptance. The anticipated strength of those trends, however, was unclear, and I proposed that they would vary depending on status. I conducted two studies designed to assess whether aggrandizing or deprecating self-presentation styles lead to differences in influence outcomes for high and low-status individuals. In Study 1, participants gave feedback and a promotion recommendation for a fictitious (male or female) job candidate based on employee evaluation information presenting the candidate as either deprecating or aggrandizing. The main findings from Study 1 were that aggrandizers were rated as less likable than deprecators. No other predictions were supported. Study 2 was an online experiment in which participants made hiring recommendations in reference to résumés from fictitious applicants that varied by race, gender, and presentation style (aggrandizing, deprecating, or neutral). Results provided some evidence that low-status candidates were punished for using aggrandizing self-presentation strategies. The results of the studies suggest no one- best technique for self-presentation and that there may be costs for aggrandizing or deprecating depending on race and gender.

La protección general atribuida en los conflictos armados no internacionales por el artículo 3 común a la población civil, de la que las niñas menores de 15 años forman parte, no depende de su filiación con alguna de las partes en el conflicto, y se extiende, en principio, a todos los actos de violencia, entre los que se encuentran los de naturaleza sexual cometidos por cualquiera de las mismas, incluyendo aquellos cometidos por los miembros de la parte en el conflicto con la que se encuentren afiliadas. Los casos contra Thomas Lubanga y Bosco Ntaganda muestran que, como regla general, las niñas menores de 15 años no desarrollan de manera prolongada actividades de participación directa en las hostilidades, por lo que, a pesar de acompañar permanente al grupo y de ser “esposas” o “compañeras” de sus comandantes, no asumen una función continua de combate y no pueden ser consideradas como miembros del mismo. Además, los actos de naturaleza sexual coercitivamente desarrollados por las niñas menores de 15 años reclutadas por las FPLC en favor de los comandantes y miembros del grupo con las que se encuentran esposadas, no cumple ninguno de los tres requisitos exigidos por el concepto de participación directa en las hostilidades porque: (a) no son idóneos para causar directamente por sí mismos el umbral de daño requerido; (b) no forman parte integral de ninguna operación militar que pudiera generar dicho umbral de daño; y (c) no poseen el nexo beligerante requerido, puesto que no están específicamente diseñados para causar un menoscabo a la parte adversa de las FLPC. Tampoco las demás actividades desarrolladas por las niñas menores de 15 años alistadas o reclutadas por las FLPC, incluyendo trabajo doméstico (donde principalmente desempeñaron tareas culinarias), transporte de comida a bases aéreas y acompañamiento a las esposas de los comandantes, cumplen, según la Sala de Primera Instancia I en el caso Lubanga, con los tres requisitos necesarios para su consideración como participación directa en las hostilidades. De ahí, que las niñas no hayan perdido en ningún momento su protección general. A todo lo anterior hay que añadir que los niños y niñas menores de 15 años, al ser una población particularmente vulnerable, gozan de una especial protección durante los conflictos armados (con independencia de su naturaleza), tal y como se manifiesta en la Convención de los Derechos del Niño de 1989, los Convenios de Ginebra de 1949 y de sus Protocolos adicionales de 1977, el Estatuto de la Corte Penal Internacional de 1998 y las Resoluciones 1882 de 2009, 1960 de 2010 y 2106 de 2013 del Consejo de Seguridad de las Naciones Unidas. Esta protección especial se extiende a los actos de violencia sexual cometidos por los miembros de las fuerzas armadas nacionales o grupos armados organizados que los alistan o reclutan. En consecuencia, la protección general y especial a que son acreedoras las niñas menores de 15 años, no se limita a las agresiones provenientes de las partes adversas en el conflicto, sino que se extiende también a la violencia sexual ejercida contra ellas por los miembros del propio grupo que las alistó o reclutó, incluso en el caso de que ésta sea ejercida por los comandantes que las tomaron como esposas o compañeras. Las niñas menores de 15 años alistadas o reclutadas entre 2002 y 2003 por las FPLC de Thomas Lubanga y Bosco Ntaganda eran sin duda acreedoras de dicha protección.

Raman microscopy of two mixite minerals BiCu6(AsO4)3(OH)6.3H2O from Jáchymov and from Smrkovec (both Czech Republic) has been used to study their molecular structure, which is interpreted and the presence of (AsO4)3-, (AsO3OH)2-, (PO4)3- and (PO3OH)2- units, molecular water and hydroxyl ions were inferred. O-H…O hydrogen bond lengths were calculated from the Raman and infrared spectra using Libowitzky’s empirical relation. Small differences in the Raman spectra between both samples were observed and attributed to compositional and hydrogen bonding network differences.
