In this thesis I investigate the impact of donor organizations on NGOs’ efforts to foster local community participation in environmental projects, by analyzing how conditions on project funding affect a sample of South African NGOs. Numerous NGOs take environmental justice as a key tenet of their work. Yet, promoting environmental justice is not an easy task to perform. Aside from cultural, political and social contingencies peculiar to specific contexts, there are external constraints that can help or hinder NGOs’ efforts, among which resource-dependency dynamics stand out as particularly relevant. In fact, donors hold power over NGOs, who must stick to specific conditions to secure their support. My aim is to understand what conditions and what type of donors facilitate or hinder community participation —a basic condition for achieving environmental justice— in environmental projects, where hindrances are exemplified by the presence of NGOization dynamics. I analyze donors’ guiding principles, eligibility criteria and monitoring and evaluation standards, delving into the provisions of five different funders that financially support local environmental projects in South Africa, classified according to their core values and organizational settings. Data are collected, coded, and analyzed with the help of NVIVO through a content analysis of calls for grants, project proposals, project reports, and semi-structured interviews to donors and NGO professionals. In this study, I argue that donor organizations can facilitate community participation and avoid NGOization dynamics by acknowledging the existence of unequal power relations between them and the NGOs they fund and by taking measures to respond to NGOs demands. This study highlights the importance of long-term engagement and a relationship based on trust between donors and NGOs as key to creating alternative funding models that help secure the goals that local communities define. Moreover, this study also claims that donors’ upward accountability has a weight in determining conditions on funds and eligibility criteria, and that many of the donors’ virtuous practices originate from their independence from upward accountability measures.

Our research aims to examine how the innovative conception of "political science", developed by Jean Bodin (1529/30-1596) in his Methodus ad facilem historiarum cognitionem (1566; 1572), falls within the scope of a humanist program which restores legal science in the name of scientia civilis. We therefore propose to investigate the line of thoughts which regard the scientia civilis in the works of two of his predecessors, Guillaume Budé and François Connan, who develop this "science" for the sake of magistrates-judges of the Parlements by devising a "method" which intends to unify legal theory with practical knowledge. Their considerations lead them to establish a new paradigm of jusnaturalism and to re-establish, in modern times, the very notion of law on the basis of right reason, id est, on the basis of a community of laws dominated only by reason: civitas universa. We bring light to the fact that, when this community is identified with the international society of his time, supposedly ruled by the ius gentium which incarnates reason, Bodin bestows upon his scientia civilis a political character. If the jusnaturalist paradigm allows him to assume the transition from a barbarous state to a human society, it is his famous theory of sovereignty (summum imperium) that, by defining the coercive power delegated to the magistrates of Parlements, allows them to realize this transition. We propose that his "method" of reading the history enables him to materialize the political science, which determines, beyond the limits of legal science, the role the government plays in realizing the human society, or in other words, the new civitas universa, governed by the ius gentium.

This PhD dissertation is a collection of four essays focusing on the demand and supply of small business finance in Kenya. The studies are the result of primary research conducted over three years with both demand-side players, more specifically micro and small-scale entrepreneurs operating in a low-income area in Nairobi. And the main suppliers of small businesses finance in Kenya - commercial banks - which provided data on the size, characteristics and evolution of their SME finance portfolio between 2009 and 2013. Since commercial banks are not the only players in the provision of finance to small firms, the dissertation studies the entire financial landscape of both formal and informal financial providers, including institutions such as microfinance institutions, savings groups and moneylenders among others. The dissertation is divided in two parts: the first half of the dissertation analyses the determinants, effects and challenges of access to formal and informal finance by small enterprises in Nairobi (Essays 1 and 2). These two essays use primary data collected through a survey questionnaire with 344 micro and small enterprises in a low income neighbourhood in Nairobi. The analysis describes the financial landscapes in which businesses operate and the effects of access to credit on firm performance (e.g. investments, profitability and employment growth.). The second half of the dissertation analyses the supply-side, more specifically the relation between formal financial sector development and economic growth (Essay 3) and the characteristics and development of bank financing to SMEs (small and medium enterprises) in Kenya (Essay 4). Essay 3 relies on secondary time-series data taken from the World Bank databases, whereas Essay 4 uses original survey data administered to commercial banks in Kenya in two survey rounds in 2012 and 2014. Each essay in this dissertation is a standalone study with its own literature survey, research questions, data and methodological approach. The main findings of the demand-side chapters is that informality has significant effects on access (or exclusion) to bank finance, but is less relevant when we investigate informal financial instruments such as self-help groups and family/friend loans. Essay 2 of the dissertation shows that different types of loans have different effects on the performance of businesses, and that loans from commercial banks seem to incentivize investments and employment creation more than other types of loans. The supply-side chapters on the other hand show that there is a long-term association between financial sector development in Kenya and economic growth, and that there is a reciprocal relation of causality over the long-run. Finally, Essay 4 shows that bank financing to SMEs has grown steadily over the last few years and that banks are increasingly exposed to small businesses in their lending portfolio. However, the financial products to SMEs tend to be unsophisticated and concentrated in few sectors.

Every human being is familiar to the experience of reminiscence: recalling and revisiting our past memories. We reminisce to create our identities. We reminisce to maintain our relationships. We reminisce to review our lives. And we also reminisce together. This dissertation develops around the topic of how IT stimulates reminiscence, motivated by its proven benefits in peopleâ s well-being and its prevalence across all stages of life. The focus is set on older adults, with the overall goal of fostering intergenerational social interactions (that is, interactions between older adults and younger generations). This thesis is motivated by the current interest on active ageing as an emergent way of life, with better and more opportunities for health, participation and security. As the world ageing population continues to increase and the average life expectancy of people increasing every year, there is a growing need for understanding the ageing phenomena, and particularly, for designing human centered information technologies (IT) that enhance opportunities of social participation as people age. Within this scenario, this dissertation addresses the following research questions using a participatory approach to research and design: (i) what is the role of IT in enabling a more happy and active ageing?; (ii) in doing so, how can IT stimulate intergenerational social interactions?, and (iii) can IT-supported social reminiscence facilitate these interactions and make of them an enjoyable experience?. To answer these questions, we leverage upon a participatory action research approach to gain an understanding of the topic, moving later to the participatory design of IT for social reminiscence and finally, evaluating how IT supports the practice of social reminiscence in a face-to-face intergenerational context. The contributions of this dissertation can be summarized as follows: - Knowledge: an understanding of what role IT can play in supporting, stimulating and accompanying active ageing and social interactions through the practice of reminiscence. - Model: a conceptual model of the different stages of IT-supported social reminiscence sessions, and an extended model of the design spaces for intergenerational engagement. - System: an exemplary socio-technical system that fits the aforementioned roles, including a knowledge base and algorithms to support contextual stimulation of reminiscence, using multimedia resources that are publicly available on the web. - Evaluation: quantitative and qualitative results obtained from observing the use of our system in a real intergenerational context.

Through a cyberethnographic informed approach applied to a mature Free and Open Source Software video game collective this research addressed a central issue in contemporary information age: the increasing place taken by users in creating and maintaining innovative public goods thanks to the distributed carrying capacity of the Internet. The empirical work is based on an ethnographic immersion in the field and on interviews and it is theoretically informed by Actor-Network Theory and integrated with insights coming from Action Nets.

Though causing water and soil contamination and serious threats to the natural environment and human well-being, waste crime has not been considered a serious crime in any society. Moreover, while the problem of waste crime has often been portrayed as the result of organized crime’s involvement in the legitimate economy, scant attention has been given to the role of legitimate economic operators in illegal waste diversion activities. Seeking profitability and cost reduction, respected companies rationally opt for managing waste illegally in the course of everyday business activities when faced with crime opportunities. Existing research has suggested that legislative loopholes or complex and ambiguous law rules can provide crime opportunities, which profit-driven market players may choose to exploit at the expense of the environment. These studies so far have been hampered by the lack of an empirical analysis of whether existing laws may facilitate or encourage illegal waste diversion activities. The present dissertation sought to examine the problem, which is mainly legal in nature, from a criminological perspective. It examined waste crime committed by legitimate economic operators, focusing specifically on the crime prosecuted in Italy under the heading of illegal traffic of waste. The purpose of such crime-specific focus was to qualitatively explore how this specific type of waste crime is committed and further identify crime opportunities provided by the legal environment in which waste management activities regularly take place. More specifically, the research attempted to determine whether legislative shortcomings within the legislation that regulates the waste management sector may bestow opportunities to lawbreaking. The analysis of the data sources in the study provided reliable evidence about the involvement of legitimate market players in illegal waste diversion activities. The research not only revealed the process through which illegal waste traffic is perpetrated by legitimate market players, but also uncovered potential crime opportunities provided by the legislation that governs the waste management sector. Furthermore, the findings indicated that shortcomings within administrative controls play a substantial role in facilitating and encouraging illegal waste diversion activities. The results form the basis for inductive inferences about the existence of a relationship between crime opportunities provided by the law and administrative controls, and economic operators’ involvement in waste crime.

This research investigates why people acquire dual citizenship. It focuses on the acquisition of dual citizenship through residency, with a processual lens and under conditions of “ordinariness” to tackle aspects that are usually overlooked. It builds on the differentiated access to dual citizenship granted to Peruvian migrants by the Italian and Spanish citizenship regimes. The 79 Peruvian migrants included in the study are either prospective dual citizens or actual dual citizens. The research builds on qualitative methods ranging from participant observation to in-depth semi-structured interviews. It investigates the motivations, expectations and contingences that bring migrants to the status acquisition. The analysis distinguishes between early and postponed acquisitions to highlight how practices of convenience and everyday forms of substantive commitment can coexist under the same national umbrella. Moreover it suggests that the availability and accessibility of the dual status cannot be conflated with a supposed desirability. Although nation-states design their citizenship and immigration regimes according to normative stances that should shape their ideal citizenry, individuals qua migrants manage to forge their own way into the host community while formally abiding the law. Thus, migrants’ pathways across statuses are the result of structural constraints as much as personal preferences and deliberate positioning vis-à-vis nation-states. The study shows how people navigate the laws through both legal and semi-legal means; how they cultivate constellations of belonging that do not necessarily match formal memberships; and how they invest citizenship with multiple meanings that can converge, collide, or simply bypass the state-led rhetoric on national membership.

In this dissertation, I have verified that the striking purple color of the intermetallic compound AuAl₂, also known as purple gold, originates from surface plasmons (SPs). This contrasts to a previous assumption that this color is due to an interband absorption transition. The existence of SPs was demonstrated by launching them in thin AuAl2 films in the Kretschmann configuration, which enables us to measure the SP dispersion relation. I observed that the SP energy in thin films of purple gold is around 2.1 eV, comparable to previous work on the dielectric function of this material. Furthermore, SP sensing using AuAl₂ also shows the ability to measure the change in the refractive index of standard sucrose solution. AuAl₂ in nanoparticle form is also discussed in terms of plasmonic applications, where Mie scattering theory predicts that the particle bears nearly uniform absorption over the entire visible spectrum with an order magnitude higher than a lightabsorbing carbonaceous particle. The second topic of this dissertation focuses on plasmon enhanced fluorescence in gold nanoparticles (Au NPs). Here, I investigated the distance-dependent fluorescence emission of rhodamine green 110 fluorophores from Au NPs with tunable spacers. These spacers consist of polyelectrolyte multilayers (PEMs) consisting of poly(allylamine hydrochloride) and poly(styrene sulfonate) assembled at pH 8.4. The distance between Au NPs and fluorophores was varied by changing the ambient pH from 3 to 10 and back, which causes the swelling and deswelling of PEM spacer. Maximum fluorescence intensity with 4.0-fold enhancement was observed with 7-layer coated Au NPs at ambient pH 10 referenced to pH 3. The last topic of this dissertation examines a novel approach to assemble nanoparticles, in particular, dimers of gold nanospheres (NSs). 16 nm and 60 nm diameter NSs were connected using photocleavable molecules as linkers. I showed that the orientation of the dimers can be controlled with the polarization of UV illumination that cleaves the linkers, making dipolar patches. This type of assembly provides a simple method with potential applications in multiple contexts, such as biomedicine and nanorobotics. / PHD / This dissertation covers three related topics. The first is an investigation of the optical properties of the unusually colored purple gold, which is a blend of gold and aluminum with the chemical formula is AuAl₂. This compound is interesting in that the origin of this color is different from most other metals. In the case of gold, for example, the metal gold is yellow color by absorbing the blue component from white light, leaving behind yellow color reflected light. The blue light is absorbed by electrons that change their state from a lower energy to a higher one. In purple gold, the color results from a different phenomenon known as “surface plasmons.” Surface plasmons are waves consisting of many electrons that move back and forth near an interface between a metal and an electrical insulator. The energy of surface plasmons in purple gold is low and corresponds to the purple color in this compound. Recently, published theoretical work supports the possibility of surface plasmons in purple gold. In this dissertation, I experimentally verify the presence of surface plasmons in purple gold. To launch surface plasmons, light was reflected off of a purple gold film deposited on the hypotenuse of a prism with varying angles of incidence. Surface plasmons can be observed by the sudden dimming of reflected light. From this, I was able to extract the surface plasmon dispersion relation, which is the relation between the inverse of the wavelength and the energy of the surface plasmons. In addition, I computed the light absorption properties of purple v gold when it is used in a nanoparticle form. The computational result showed that small purple gold nanoparticles absorb light very well, which may be useful in photothermal cancer therapy and solar steam generation. The second dissertation topic comprises a study of fluorescent molecules. These are compounds that reemit light with a different and redder color than the color of the light that illuminates them. In this experiment, green fluorescent molecules were placed near the surface of gold nanoparticles to observe how the brightness of the light emission is affected by the distance between the molecule and the metal. The underlying mechanism is based on localized surface plasmon resonances in gold nanoparticles. Localized surface plasmon resonances are waves consisting of many electrons that oscillate inside the particle, and they only occur when light at certain frequency illuminate the particle. On the resonance, the particle also exhibits the brighter light around the particle’s surface but the dimmer light away from the particle’s surface. The light enhancement from the particle can change the light emission of the fluorescent molecules. If the fluorescent molecules were placed in the range of localized surface plasmon resonances, the light emission is increased owing to the brighter light from the particle. However, if the fluorescent molecules were placed further away from the range of localized surface plasmon resonances, the light emission is decreased owing to the dimmer light from the particle. The distance between the surface of gold nanoparticle and the fluorescent molecules was varied by wrapping the gold particles with ultra-thin films of different plastic polymers before attaching fluorescent molecules to the surface of the films. These polymer films have the property that they swell and shrink when the acidity and basicity of the solution of gold particles changes, which allows me to vary the distance between the gold particles and fluorescent molecules. The results showed that the observed light gets dimmer when the solution is more acidic. On the other hand, the brighter light is noticed when the solution is more basic, and this observation is repeatable many times. Moreover, my work differs from other published works vi in that the particles with the polymer films are more robust and stable than the other particles. This allows more design flexibility and suggests applications in biomedical or environmental research where the particles can be used to locally measure properties, such as acidity in confined spacers such as living cells. It may be possible to use this technique for tumor cells in our body or toxic pollutants in the air or water. The last dissertation topic involves assembling nanoparticles to build them into larger structures. In this experiment, I fabricated particle dimers that consisted of two gold nanospheres of different sizes. They were attached together by using small molecules that are sensitive to ultraviolet (UV) light, where these molecules allow small gold nanospheres to be attached to large gold nanospheres only in those locations on the large nanospheres that have been illuminated with a sufficient amount of UV light. To achieve this alignment, UV light with a linear polarization (a specific electric field direction) was used to select the area on the large nanospheres where the UV light was particularly intense and therefore able to break the molecules, leaving positively charged surface patches on the spheres. This results in the electrostatic attraction between the positive patches on the large gold nanospheres and the negatively charged small gold nanospheres. With this method, I was able to make dimers of nanospheres in a preferred alignment by changing the polarization of UV light. The experimental results showed a good yield of dipolar patches, which allows multifunctional nanostructures with applications in nanomedicine, optical sensing, nanoelectronics, etc.

Negli ultimi anni, la gestione illegale dei rifiuti ha attirato l’attenzione pubblica e dell’accademia. A causa delle sue conseguenze negative non solo per l’ambiente, ma anche per la salute pubblica e la crescita economica, gli esperti hanno cominciato ad esplorare le dinamiche del fenomeno e le possibilità di prevenzione. Alcuni studi hanno evidenziato l’esistenza di diversi fattori che possono determinare la gestione illegale dei rifiuti, ma pochi di essi hanno empiricamente testato la validità dei fattori stessi. Di conseguenza, si avverte la necessità di produrre nuova conoscenza sull’argomento. Il presente studio consiste in un’analisi esplorativa di fattori socio-economici, fattori di policy e di performance, e fattori criminali che influenzano la gestione illegale dei rifiuti in Italia. Dopo aver identificato le determinanti considerate rilevanti dalla letteratura, l’obiettivo è quello di testarle empiricamente. Per prima cosa, grazie all’unicità di un dataset creato sul contesto italiano, nello studio si indaga quantitativamente l’effetto di diversi fattori sul fenomeno attraverso un’analisi econometrica. Successivamente, lo studio prosegue con un’analisi “crime script” al fine di esplorare quali fattori suggeriti dalla letteratura e testati nella parte quantitativa emergono anche da casi studio e come effettivamente intervengono nel ciclo dei rifiuti italiano. I risultati indicano che la gestione illegale dei rifiuti è determinata da: i) uno scarso sviluppo economico e demografico, un alto livello d’istruzione nel territorio, la presenza di turisti; ii) l'inefficienza della normativa ambientale, delle forze dell’ordine e delle prestazioni sui rifiuti; iii) la presenza di criminalità organizzata e la diffusione di crimini economici e fiscali. Prendendo spunto da questi risultati, lo studio non solo aumenta la conoscenza sul fenomeno, ma è anche in grado di avanzare alcuni suggerimenti di policy per contrastare efficacemente le condotte illegali legate alla gestione dei rifiuti. / In the last several decades, illegal waste management (IWM) has attracted great academic and public attention. Due to its negative consequences not only for the environment, but also for public health and economic growth, scholars started to be interested in the dynamics of IWM and in how to prevent it. Some studies stressed the existence of different factors that can determine the phenomenon, but very few of them have empirically tested their validity. Consequently, developing new research on the topic is still necessary. The present study conducts an explorative analysis of the socio-economic, policy and performance-driven and criminal factors influencing IWM in Italy. After the identification of the most relevant determinants according to the literature, the objective is to empirically test them. First, thanks to a unique dataset focused on the Italian context, the study quantitatively investigates the effect of different factors on the phenomenon through an econometric analysis. Second, the study realises a crime script analysis to explore which factors suggested by the literature and tested in the quantitative part emerge also in concrete case studies and how they effectively intervene in the Italian waste cycle. Results indicate that IWM is determined by: i) a low level of economic development and population density, a high level of education and tourists’ presence; ii) inefficiency in environmental regulation, enforcement and waste performances; iii) the presence of organised crime and the diffusion of economic and fiscal crimes. According to these findings, the study not only deepens the knowledge of the phenomenon, but it is also able to provide some policy suggestions to efficiently hinder illegal conducts related to waste management.

Il Bilancio Partecipativo (BP) è probabilmente l’esempio più famoso ed interessante di governance locale per i suoi effetti democratici e redistributivi. Per via del coinvolgimento diretto dei cittadini nel processo decisionale, il BP è considerato una forma di democrazia diretta capace di ovviare agli attuali limiti della democrazia rappresentativa moderna. Tuttavia, ad un’attenta analisi, è possibile identificare nel suo funzionamento anche degli elementi rappresentativi che non sono mai stati presi molto in seria considerazione. Infatti, poiché la partecipazione avviene solitamente attraverso gruppi ed associazioni, nuove forme di rappresentanza e nuovi rappresentanti emergono in competizione con quelli tradizionali politici in termini di consenso, sostegno popolare e dunque legittimità. Il presente lavoro vuole andare oltre il pensiero corrente e proporre un’interpretazione originale del modello istituzionale del BP come una forma nuova ed alternativa di democrazia rappresentativa, in cui le organizzazioni della società civile assumono un ruolo centrale: dietro al BP vi sarebbe una sorta di democrazia ‘civile’. Questo punto di vista alternativo non solo può stimolare un ulteriore dibattito in letteratura, ma aprire anche degli scenari interessanti in relazione ai temi più generali della crisi delle istituzioni liberal-democratiche e del ruolo e dell’identità della società civile. / Participatory Budgeting (PB) is probably the most famous and interesting example of innovative local governance for its redistributive and democratic effects. Due to the direct involvement of citizens in the decision-making process, PB is celebrated as an example of direct democracy which can help to deal with the limits of representative democracy. However, on closer analysis, it is possible to identify elements of representation in its functioning, which are taken into little consideration and which could probably modify the prevalent theoretical belief. In fact, as citizens usually participate through their groups and associations, new representatives emerge challenging the traditional channels of political representation in terms of popular approval, consensus, hence legitimacy. This work aims to go beyond the prevailing narrative and propose an original interpretation of the PB’s institutional model as a new and alternative representative democracy, where the main political actors become organizations from the civil society: behind PB there seems to lie a sort of ‘civil’ democracy. Hence, introducing this alternative viewpoint can, not only further questions which are never fully considered in the literature, but also open interesting scenarios in the debate over the crisis of liberal-democratic institutions and the role and the identity of civil society.
