In the era of the Internet of Everything, a user with a handheld or wearable device equipped with sensing capability has become a producer as well as a consumer of information and services. The more powerful these devices get, the more likely it is that they will generate and share content locally, leading to the presence of distributed information sources and the diminishing role of centralized servers. As of current practice, we rely on infrastructure acting as an intermediary, providing access to the data. However, infrastructure-based connectivity might not always be available or the best alternative. Moreover, it is often the case where the data and the processes acting upon them are of local scopus. Answers to a query about a nearby object, an information source, a process, an experience, an ability, etc. could be answered locally without reliance on infrastructure-based platforms. The data might have temporal validity limited to or bounded to a geographical area and/or the social context where the user is immersed in. In this envisioned scenario users could interact locally without the need for a central authority, hence, the claim of an infrastructure-less, provider-less platform. The data is owned by the users and consulted locally as opposed to the current approach of making them available globally and stay on forever. From a technical viewpoint, this network resembles a Delay/Disruption Tolerant Network where consumers and producers might be spatially and temporally decoupled exchanging information with each other in an adhoc fashion. To this end, we propose some novel data gathering and dissemination strategies for use in urban-wide environments which do not rely on strict infrastructure mediation. While preserving the general aspects of our study and without loss of generality, we focus our attention toward practical applicative scenarios which help us capture the characteristics of opportunistic communication networks.

Microfinance is an initiative which seeks to address financial inclusion, micro-entrepreneurship, and poverty reduction without over burdening governments. However, the current sector of microfinance is still heavily dependent on the good will of donors. The over-reliance on donations is a feature which threatens the long term sustainability of microfinance. Much has been written about this reliance, but research to date hasn’t empirically examined the effect of regulation as a mediator. This is a critical area of study because regulation directly affects Microfinance Institutions’ (MFI) innovation, and innovation is what shapes the future of microfinance. This thesis considers the role that regulation plays in affecting MFI’s and their ability to innovate in products, services and long-term sustainability via access to capital. Interviews were undertaken with stakeholders in MFI’s, NGO’s, Self-Regulating Bodies, and Regulators in India, Pakistan, and Bangladesh. This thesis discusses findings from interviews in relation to regulatory measures regarding financial self-sustainability of MFI’s. The conclusions of this thesis have implications for policy and inform the microfinance literature.

Nel 1932 Ernst Robert Curtius pubblica il pamphlet politico culturale Deutscher Geist in Gefahr nel quale chiarisce il suo pensiero di fronte alla grave crisi in cui versa la Germania. Egli si schiera contro le posizioni di destra del suo tempo, delle quali critica apertamente la boria nazionalista, il rozzo antisemitismo e la creazione di un mito nazionale elaborato come strumento di manipolazione dell’opinione pubblica. Ritiene inoltre inaccettabili le posizioni rivoluzionarie, tanto di destra quanto di sinistra, che vogliono liberarsi della tradizione umanistica europea e disprezzano la Zivilisation francese; allo stesso modo rifiuta l’ideale di un germanesimo eroico avulso dalla storia europea e respinge infine tutte le forme di nichilismo che si risolvono in un atteggiamento di indifferenza nei confronti della realtà, dei valori e della storia. Curtius accetta il sistema democratico come unica soluzione e ritiene che le decisioni politiche debbano mirare al bene di tutti i ceti sociali indipendentemente dagli interessi di partiti e di singoli gruppi. Rifiuta qualunque forma, anche culturale, di supremazia della Germania, aspira a un’Europa cosmopolita, le cui nazioni siano valorizzate nelle loro caratteristiche specifiche, ed è convinto che per la costruzione della pace gli europei debbano vivere, studiare e lavorare insieme imparando gli uni le lingue degli altri. Per Curtius l’Umanesimo della tradizione classica e la letteratura del Medioevo sono parte integrante della vita di ogni europeo e fonte di energie spirituali per affrontare in modo creativo il presente e il futuro.

In the present thesis I study the contribution to firm value of inventories management from a risk management perspective. I find a significant contribution of inventories to the value of risk management especially through the operating flexibility channel. In contrast, I do not find evidence supporting the view of inventories a reserve of liquidity. Inventories substitute, albeit not perfectly, derivatives or cash holdings. The substitution between hedging with derivatives and inventory is moderated by the correlation between cash flow and the underlying asset in the derivative contract. Hedge ratios increase with the effectiveness of derivatives. The decision to hedge with cash holdings or inventories is strongly influenced by the degree of complementarity between production factors and by cash flow volatility. In addition, I provide a risk management based explanation of the secular substitution between inventories and cash holdings documented, among others, in Bates et al. (2009), Journal of Finance. In a sample of U.S. firms between 1980 and 2006, I empirically confirm the negative relation between inventories and cash and provide evidence on the poor performance of investment cash flow sensitivities as a measure of financial constraints also in the case of inventories investment. This result can be explained by firms' scarce reliance on inventories as a reserve of liquidity. Finally, as an extension of my study, I contrast with empirical data the theoretical predictions of a model on the integrated management of inventories, trade credit and cash holdings.

The article explores the developments in German-language anthropology in the past decades, focussing on the period after the 1970s. It argues that the recent history of German-language Ethnologie (social and cultural anthropology) is one of catching-up modernization. German-speaking anthropologists are increasingly involved in, and contribute to, broader theoretical debates, publish in English and in international journals, and are actively engaged in international academic networks. The paper discusses how and under what conditions of knowledge production these transformations have taken place. It analyses the changing institutional environment in which German anthropologists have worked and work today, as well as the theoretical impulses from within and outside the discipline that have given rise to the contemporary orientation of German-language anthropology as an anthropology of the 'present'. Finally, and beyond the focus on Germany, the article offers some ideas on the future of anthropology as a symmetrical social science, characterized by a continued strong reliance on field work and a high level of 'worldliness', a basic attitude of systematically shifting perspectives, the critical reflection of the social and political embeddedness of knowledge production, and an engagement with social theory across disciplinary boundaries.

In 2011, researchers at Bucknell University and Illinois Wesleyan University compared the search efficacy of Serial Solutions Summon, EBSCO Discovery Service, Google Scholar and conventional library databases. Using a mixed-methods approach, qualitative and quantitative data was gathered on students’ usage of these tools. Regardless of the search system, students exhibited a marked inability to effectively evaluate sources and a heavy reliance on default search settings. On the quantitative benchmarks measured by this study, the EBSCO Discovery Service tool outperformed the other search systems in almost every category. This article describes these results and makes recommendations for libraries considering these tools.

As a female-only festival in a significantly gender-segregated society, sāmā cakevā provides a window into Maithil women’s understandings of their society and the sacred, cultural subjectivities, moral frameworks, and projects of self-construction. The festival reminds us that to read male-female relations under patriarchal social formations as a dichotomy between the empowered and the disempowered ignores the porous boundaries between the two in which negotiations and tradeoffs create a symbiotic reliance. Specifically, the festival names two oppositional camps—the male world of law and the female world of relationships—and then creates a male character, the brother, who moves between the two, loyal to each, betraying, in a sense, each, but demonstrating, by his movements, the currents and avenues of power. This article makes available to other scholars of South Asian culture and society an extended description and analysis of this distinctive festival, while also contributing to the scholarly discussion of women’s expressive traditions.

We present a multistage strategy to define the scale and geographic distribution of 'local' ceramic production at Lydian Sardis based on geochemical analysis (NAA) of a large diverse ceramic sample (n = 281). Within the sphere of local ceramic production, our results demonstrate an unusual pattern of reliance on a single resource relative to other contemporary Iron Age centers. When our NAA results are combined with legacy NAA provenience data for production centers in Western Anatolia, we can differentiate ceramic emulation from exchange, establish probable proveniences for the non-local component of the dataset, and define new non-local groups with as yet no known provenience.

Numerical simulations of eye globes often rely on topographies that have been measured in vivo using devices such as the Pentacam or OCT. The topographies, which represent the form of the already stressed eye under the existing intraocular pressure, introduce approximations in the analysis. The accuracy of the simulations could be improved if either the stress state of the eye under the effect of intraocular pressure is determined, or the stress-free form of the eye estimated prior to conducting the analysis. This study reviews earlier attempts to address this problem and assesses the performance of an iterative technique proposed by Pandolfi and Holzapfel [1], which is both simple to implement and promises high accuracy in estimating the eye's stress-free form. A parametric study has been conducted and demonstrated reliance of the error level on the level of flexibility of the eye model, especially in the cornea region. However, in all cases considered 3-4 analysis iterations were sufficient to produce a stress-free form with average errors in node location <10(-6)mm and a maximal error <10(-4)mm. This error level, which is similar to what has been achieved with other methods and orders of magnitude lower than the accuracy of current clinical topography systems, justifies the use of the technique as a pre-processing step in ocular numerical simulations.

Today, crude oil remains a vital resource all around the world. This non-renewable resource powers countries worldwide. Besides serving as an energy source, crude oil is also the most important component for different world economies, especially in developing countries. Ecuador, a small member of the OPEC oil cartel, presents a case where its economy is oil dependent. A great percentage of the country¿s GDP and government¿s budget comes from oil revenues. Ecuador has always been a primary exporter of raw materials. In the last centuries, the country experienced three important economic booms: cacao, bananas, and, ultimately, crude oil. In this sense, the country has not been able to fully industrialize and begin to export manufactured goods, i.e., Ecuador suffers from the Dutch disease. The latter has deterred Ecuador from achieving broad-based economic development. Given crude oil¿s importance for the Ecuadorian economy, the government has always tried to influence the oil industry in search of profits and benefits. Therefore, this thesis, explores the question: how and to what extent have political interventions affected the oil industry in Ecuador from 1990 until March 2014? In general, this thesis establishes an economic history context during the last twenty-four years, attempting to research how political interventions have shaped Ecuador¿s oil industry and economy. In the analysis, it covers a period where political instability prevailed, until Rafael Correa became president. The thesis examines Ecuador¿s participation in OPEC, trying to find explanations as to why the country voluntarily left the organization in 1992, only to rejoin in 2007 when Correa rose to power. During the ¿Revolución Ciudadana¿ period, the thesis researches reforms to the Law of Hydrocarbons, variations in the relations with other nations, the controversy surrounding the YasunÃ-ITT oil block, and the ¿RefinerÃa del PacÃfico¿ construction. The thesis is an Industrial Organization detailed case study that analyzes, updates, and evaluates the intersection of economics and politics in Ecuador¿s crude oil industry during the last 24 years. In this sense I have consulted past theses, newspaper articles, books, and other published data about the petroleum industry, both from a global and Ecuadorian perspective. In addition to published sources, I was able to interview sociologists, public figures, history and economics academics, and other experts, accessing unique unpublished data about Ecuador¿s oil industry. I made an effort to collect information that shows the private and public side of the industry, i.e., from government-related and independent sources. I attempted to remain as objective as possible to make conclusions about the appropriate Industrial Organization policy for Ecuador¿s oil industry, addressing the issue from an economic, social, political, and environmental point of view. I found how Ecuador¿s political instability caused public policy to fail, molding the conduct and market structure of the crude oil industry. Throughout history, developed nations have benefited from low oil prices, but things shifted since oil prices began to rise, which is more beneficial for the developing nations that actually possess and produce the raw material. Nevertheless, Ecuador, a victim of the Dutch disease due to its heavy reliance on crude oil as a primary product, has not achieved broad-based development.

Since the turbulence of 1989, the countries of Central and Eastern Europe have striven to "return to Europe". Agreements have been signed with ten post-communist countries, beginning in 1991 with Czechoslovakia (before its division), Hungary and Poland. Since that time several countries have expressed a desire to become members of the EU. In 1997 the European Commission announced its opinion on the applications for EU membership of the Czech Republic, Hungary, Poland, Slovakia, and seven other applicant countries. The Commission recommended the commencement of negotiations on accession with the Czech Republic, Estonia, Hungary, Poland, and Slovenia. Mr. Kucia's report, presented in the form of a series of manuscripts totalling 91 pages, written in English and Polish and including many pages of tables and graphs, presents the results of a study of public opinion on European integration in four countries of Central Europe (CE): the Czech Republic (CZ), Hungary (H), Poland (PL), and Slovakia (SK). The research results are primarily based on a public-opinion survey known as the Central and Eastern Eurobarometer (CEEB). CEEB has been conducted on behalf of the European Commission in the Central and Eastern European countries each year in autumn since 1990. Below is a very small selection of Mr. Kucia's research findings. Throughout the 90s people in the four countries increasingly saw their countries' future tied up with the EU, since economic and political connections to the EU were growing and prospects for EU membership were increasing. Regional co-operation within CE did not gain much popular recognition. However, initially high levels of enthusiasm for the EU were gradually superseded by a more realistic approach or even scepticism. Poland was the exception in this respect; its population was more positive about the EU in 1996 than ever before. Mr. Kucia concludes that, since the political "elites" in CE are more positive about the EU than the people they serve, they should do their best to bring people round to their beliefs, lest the project of European integration become purely the business of the elites, as Mr. Kucia claims it has been in the EU up till now. He accuses the governments of the region, the EU authorities and the media of failing to provide appropriate information, especially about the two subjects which most affect them, association with the EU and the PHARE assistance programme. Respondents were asked to rank in order the countries or regions they saw their country's future most closely tied up with. In the period 92-96 the EU received the highest ratings in all of CE. The ratings were highest in CZ in 92 and 93 (46%) and in Poland in 96 (46%). They were the lowest in Hungary (22% in 94). After the EU came "Other Western European countries (non EU)", that is Austria, Sweden and Finland (before they joined the EU in 1995), Switzerland and Norway. Mr. Kucia puts the high ratings of these countries down to historical connections and geographical proximity, particularly in the case of Austria. The USA always came second in Poland, and in Hungary too its standing has always been higher than in CZ or SK. Indeed Mr. Kucia suggests that the USA's standing is disproportionately low in especially the CZ. Germany was nominated frequently by Hungarians, though in the CZ and SK, figures have been consistently low (1-2%). "Other CE/EE countries" increased their ratings in all of CE except Poland between 92 and 96. With regard to these last figures, Mr. Kucia makes an interesting note. Assuming that for the respondents in the four countries this category covered the Visegrad 4, least support was found in Poland, whose government was the most in favour of close political co-operation within the V4, while most support was in evidence in CZ and SK, for whose governments V4 was simply not a priority. Again, there is evidence of a divide between the political elites and the people. Russia has occupied a consistently modest rank. It was the highest in PL, fairly low in H and SK and the lowest in CZ. The Slovak government's policy of closer ties with Russia is reflected in a growth in the figures from 2% in 93 to 6% in 95. Every year the spontaneous answer "we should depend on ourselves" appeared, which Mr. Kucia interprets as either a sign of isolationism and disillusionment or as a call for self-reliance. Unfortunately he regards both these tendencies as unfeasible in the uniting Europe. Moving to more general conclusions, Mr. Kucia finds that the concept "Central Europe" does not have much meaning for Central Europeans. He believes that this is probably due to the failure to establish a viable regional co-operation network. Group discussions also revealed that people thought themselves European as a consequence of being Czech or Polish etc. Thus European identity is based on national identities. Generally within the surveyed period, the numbers of those who said they often think themselves European decreased, while the numbers of those who said they never think themselves European increased from 41% in PL, 36% in CZ, and 30% in H in 1990, to 67% in CZ, 58% in PL, and 51% in H in 1995.

The project studied the perception of parenting styles and their relation to self-development, cognitive styles, and individualisation in adolescence. Typical parenting styles of mothers and fathers were studied in five different maternal and paternal parenting backgrounds: warm authoritarian, warm democratic, cold neglectful, cold authoritarian, and neutral. Perception of different styles of parenting (for fathers: authority, 'maintaining distance' behaviour, reciprocity, enhancing self-reliance; for mothers: authority, unpredictable behaviour, mutual trust, achievement orientation, and enhancing self-reliance) were analysed in each group using the newly developed Hungarian Parenting Questionnaire (Sallay & Munnich, 1999). This questionnaire has a theoretical basis in the ideas of Harvey (1966, 1967), where the socialisation process is combined with self-development. This categorisation of paternal and maternal parenting backgrounds enabled Sallay to explore and describe in detail how diverse parenting styles contribute to self-development, the development of cognitive complexity, and individualisation. The results show that diverse parenting by mothers and fathers produces differing impacts in nuclear and divorced families and for males and females, taking into consideration such self-components as physical, active, psychological (capabilities, personality, emotions, roles, preferences), social and reflective selves. Cognitive self-complexity varied according to parenting styles and genders: maternal and paternal parenting proved to have the most significant impact on self-complexity in a warm, democratic family. With respect to individualistic tendencies, adolescent boys were most individualistic in a cold, neglectful paternal background in nuclear families as compared to other paternal and maternal family backgrounds and to females.

In this research the supportive role of the family in coping with everyday problems was studied using two large data sets. The results show the importance of the structural aspect of social support. Mapping individual preferences to support referents showed the crucial role of spouse and parents in solving everyday problems. The individual choices of particular support referents could be fairly accurately predicted from knowledge of the composition of the family, in both categorical regression and logit models. The far lower predictability of the criterion variable was shown using a wide range of socioeconomic, social and demographic indicators. Residence in small cities and indicators of extreme occupational strata were particularly predictive of the choice of support referent. The supportive role of the family was also traced in the personal projects of young adults, which were seen as ecological, natural and dynamic middle-level units of analysis of personality. Different aspects of personal projects, including reliance on social support referents, turned out to be highly interrelated. One the one hand, expectations of support were determined by the content of the project, and on the other, expected social support also influences the content of the project. Sivuha sees this as one of the ways others can enter self-structures.

The relationship between obesity and heart rate variability (HRV) has been studied in adults and adolescents, but is not determined in young pediatrics. The purpose of this study was to assess autonomic activity using HRV in a pediatric population. We hypothesized that obese children would have reduced parasympathetic and increased sympathetic activity compared to age-matched subjects. 42 pediatric subjects (ages 3-5) were classified into 3 groups based on body mass index-for-age; normal, overweight and obese. HRV and respiratory rate were recorded during 3 minute baseline, 2 minute isometric handgrip and 3 minute recovery. HRV was analyzed in the time domain [heart rate (HR), RR interval (RRI) and RRI standard deviation (RRISD)] and frequency domain [low frequency (LF), high frequency (HF) and LF/HF ratio] using repeated measures ANOVA. Spearman’s correlations were used to examine the relations between BMI and HRV at rest. Significant condition effects were found between baseline, exercise and recovery, but these responses were not significantly different between the normal, overweight and obese children. BMI was negatively correlated with LF/HF, while BMI was positively correlated with RRISD, LF, HF and nHF. Our data demonstrate that higher BMI in the pediatric population is correlated with higher parasympathetic and lower sympathetic activity. These findings are contrary to HRV responses observed in adults and adolescents, suggesting complex relationships between age, obesity and autonomic control of the heart. The data supports the concept of an age reliance of HRV and a novel relationship between adiposity and body mass index in 3-5 year olds.
