Energy, emergy, and the city

In his book “Environment, Power, and Society” (1971) H.T. Odum introduced a picture of the energy metabolism of a city based on Wolman's paper from 1965 (Sci. Am., 213: 179-190). With the development of the emergy analysis--a branch of energy systems accounting--several authors have contributed to develop quantitative measures of HT Odum’s picture, which from many perspectives are diverging from traditional energy studies. In this paper, studies using emergy analysis to study cities are reviewed. The research regarding emergy and cities had during the period 1975-1995 its focus on cities in the United States, e.g. Miami, Jacksonville, San Francisco and Chicago. The research during 1995-2005 was almost exclusively focused on Taipei. From approximately 2006 up till 2015 the research focus has been on Chinese cities; Macao, Beijing and 37 other Chinese cities have been investigated. But there are resent also studies made on Rome (Italy) and Montreal (Canada). Studies up to about 2007/2008 were generally concerned with understanding spatial aspects of the cities investigated. After that, evaluating the sustainability of cities has become a main research focus.

Factors influencig software migration decision: case studies of acerlormittal Tubarão and the city government of Serra, Espirito Santo

The objective of this research is to identify the factors that influence the migration of free software to proprietary software, or vice-versa. The theoretical framework was developed in light of the Diffusion of Innovations Theory (DIT) proposed by Rogers (1976, 1995), and the Unified Theory of Acceptance and Use of Technology (UTAUT) proposed by Venkatesh, Morris, Davis and Davis (2003). The research was structured in two phases: the first phase was exploratory, characterized by adjustments of the revised theory to fit Brazilian reality and the identification of companies that could be the subject of investigation; and the second phase was qualitative, in which case studies were conducted at ArcelorMittal Tubarão (AMT), a private company that migrated from proprietary software (Unix) to free software (Linux), and the city government of Serra, in Espírito Santo state, a public organization that migrated from free software (OpenOffice) to proprietary (MS Office). The results show that software migration decision takes into account factors that go beyond issues involving technical or cost aspects, such as cultural barriers, user rejection and resistance to change. These results underscore the importance of social aspects, which can play a decisive role in the decision regarding software migration and its successful implementation.

The Farm, the city, and the emergence of social security

We study the social, demographic and economic origins of social security. The data for the U.S. and for a cross section of countries suggest that urbanization and industrialization are associated with the rise of social insurance. We describe an OLG model in which demographics, technology, and social security are linked together in a political economy equilibrium. In the model economy, there are two locations (sectors), the farm (agricultural) and the city (industrial) and the decision to migrate from rural to urban locations is endogenous and linked to productivity differences between the two locations and survival probabilities. Farmers rely on land inheritance for their old age and do not support a pay-as-you-go social security system. With structural change, people migrate to the city, the land loses its importance and support for social security arises. We show that a calibrated version of this economy, where social security taxes are determined by majority voting, is consistent with the historical transformation in the United States.

Socio-demographic analysis of youth in the Caribbean- a three country case study

Many Caribbean youth are doing reasonably well. They live in loving and caring families, attend school and are involved in various social activities in their communities. The health and well-being of the children and youth1 in the Caribbean is, and has been, the centre of attention of many studies, meetings and policy directives set at the regional, subregional and national levels. Programmes have been put in place to address the basic needs of young children in the areas of health and education and to provide guidance and directives to youth and adolescents in the area of professional formation and transition to adulthood. Critical issues such as reproductive health and family planning combined with access to education and information on these topics have been promoted to some extent. And finally, the Caribbean is known for rather high school enrolment rates in primary education that hardly show any gender disparities. While the situation is still good for some, growing numbers of children and youth cannot cope anymore with the challenges experienced quite early in their lives. Absent parents, instable care-taking arrangements, violence and aggression subjected to at home, in schools and among their friends, lack of a perspective in schools and the labour-market, early sexual initiation and teenage pregnancies are some of those issues faced by a rising number of young persons in this part of the world. Emotional instability, psychological stress and increased violence are one of the key triggers for increased violence and involvement in crime exhibited by ever younger youth and children. Further, the region is grappling with rising drop-out rates in secondary education, declining quality schooling in the classrooms and increasing numbers of students who leave school without formal certification. Youth unemployment in the formal labour market is high and improving the quality of professional formation along with the provision of adequate employment opportunities would be critical to enable youth to complete consistently and effectively the transition into adulthood and to take advantage of the opportunities to develop and use their human capital in the process. On a rather general note, the region does not suffer from a shortage of policies and programmes to address the very specific needs of children and youth, but the prominent and severe lack of systematic analysis and monitoring of the situation of children, youth and young families in the Caribbean does not allow for targeted and efficient interventions that promise successful outcomes on the long term. In an effort to assist interested governments to fill this analytical gap, various initiatives are underway to enhance data collection and their systematic analysis2. Population and household censuses are conducted every decade and a variety of household surveys, such as surveys of living conditions, labour force surveys and special surveys focusing on particular sub-groups of the population are conducted, dependent on the resources available, to a varying degree in the countries of the region. One such example is the United Nations Children’s Fund (UNICEF)-funded Multi-Indicator Cluster Surveys (MICS) that assess the situation of children and youth in a country. Over the past years and at present, UNICEF has launched a series of surveys in a number of countries in the Caribbean3. But more needs to be done to ensure that the data available is analyzed to provide the empirical background information for evidence-based policy formulation and monitoring of the efficiency and effectiveness of the efforts undertaken.

Circular migration and the Internet: The role of social networks in the sociocultural context of Mexican residents in Barcelona

This work focuses on the study of the circular migration between America and Europe, particularly in the discussion about knowledge transfer and the way that social networks reconfigure the form of information distribution among people, that due to labor and academic issues have left their own country. The main purpose of this work is to study the impact of social media use in migration flows between Mexico and Spain, more specifically the use by Mexican migrants who have moved for  multiple years principally for educational purposes and then have returned to their respective locations in Mexico seeking to integrate themselves into the labor market. Our data collection concentrated exclusively on a group created on Facebook by Mexicans who mostly reside in Barcelona, Spain or wish to travel to the city for economic, educational or tourist reasons.  The results of this research show that while social networks are spaces for exchange and integration, there is a clear tendency by this group to "narrow lines" and to look back to their homeland, slowing the process of opening socially in their new context.

Greening the city: an ecosystem-based framework to support planning towards urban sustainability and resilience

Cities are small-scale complex socio-ecological systems, that host around 60% of world population. Ecosystem Services (ES) provided by urban ecosystems offer multiple benefits necessary to cope with present and future urban challenges. These ES include microclimate regulation, runoff control, as well as opportunities for mental and physical recreation, affecting citizen’s health and wellbeing. Creating a balance between urban development, land take containment, climate adaptation and availability of Urban Green Areas and their related benefits, can improve the quality of the lives of the inhabitants, the economic performance of the city and the social justice and cohesion aspects. This work starts analysing current literature around the topic of Ecosystem Services (ES), Green and Blue Infrastructure (GBI) and Nature-based Solutions (NBS) and their integration within current European and International sustainability policies. Then, the thesis focuses on the role of ES, GBI and NBS towards urban sustainability and resilience setting the basis to build the core methodological and conceptual approach of this work. The developed ES-based conceptual approach provides guidance on how to map and assess ES, to better inform policy making and to give the proper value to ES within urban context. The proposed interdisciplinary approach navigates the topic of mapping and assessing ES benefits in terms of regulatory services, with a focus on climate mitigation and adaptation, and cultural services, to enhance wellbeing and justice in urban areas. Last, this thesis proposes a trans-disciplinary and participatory approach to build resilience over time around all relevant urban ES. The two case studies that will be presented in this dissertation, the city of Bologna and the city of Barcelona, have been used to implement, tailor and test the proposed conceptual framework, raising valuable inputs for planning, policies and science.

Corporal punishment : understanding the debate in Canada

There has been considerable debate over whether corporal punishment against children should be prohibited in Canada. Various organizations, most notably the Canadian Foundation for Children, Youth and the Law, have argued that the Canadian Government should ban the use of corporal punishment by repealing the specific section of the Canadian Criminal Code that provides parents with a legal defence to use corporal punishment against their children; this provision is outlined in Section 43 of the Criminal Code. Recently, the Canadian Foundation for Children, Youth and the Law challenged the constitutionality of Section 43 before the Supreme Court of Canada. The organization claimed Section 43 is unconstitutional. It violates children's Charter rights, such as the right to security of a person (Section 7), the right to be protected from cruel and unusual treatment (Section 12), and denies children the same protection adults receive under the law. Both the Canadian government and the Supreme Court of Canada reject the Foundation's arguments. Examining the federal government and the judicial system's rationale for refusing to remove Section 43 of the Canadian Criminal Code discloses how the parent-child relationship is perceived. This thesis examines how the parent-child relationship is perceived by the Canadian government and the issues that arise from such a view. This examination is essential for the comprehension of why Canada's corporal punishment law was enacted and remains in effect today.

The Colonel Kerby Chapter of Fort Erie, Ontario began on August 19, 1914 under the direction of Captain the Reverend A.C. Mackintosh. The chapter was named after Colonel James Kerby who was a legislator and a soldier. This chapter worked during two world wars raising large sums of money for war work, the community, health and education. In 1931, this chapter created the Douglas Memorial I.O.D.E. Hospital Fund to assist needy veterans. Other fundraisers included: their Salvage Shop, card parties and the Margaret Graham Memorial which raised funds for the Canadian Institute for the Blind. In June of 1989 the last meeting of the chapter took place.

Le jeune téléspectateur, objet de discours social : le cas du Chili «post-1990»

Cette thèse s’interroge sur le phénomène du jeune téléspectateur contemporain. Je questionne cette « réalité », qui fait l’objet de discours et de pratiques sociales au quotidien. L’idée de l’existence « objective » de l’enfant téléspectateur depuis l’avènement de la télévision est si fertile, qu’elle a même contribué au développement d’un sous-domaine de recherche en communication : la communication jeunesse. J’inclus également ce sous-domaine dans la problématique. Ce faisant, je tente d’esquisser une théorisation de l’enfant téléspectateur, en le comprenant comme une formation discursive et sociale. Suivant le point de vue de l’analyse de discours de Michel Foucault (1969), j’axe son étude en articulant deux éléments qui forment les objets sociaux : le régime de vérité et les formations discursives. Ainsi, je réfléchis au jeune téléspectateur comme objet de savoir et de vérité, et comme fruit d’un ensemble de formations discursives. J’ancre empiriquement le questionnement du jeune téléspectateur contemporain dans le Chili « post-1990 ». Je propose une approche méthodologique et analytique me permettant de rendre compte de l’articulation d’éléments hétérogènes qui participent au façonnement discursif et social de celui-ci. Cet outil exploratoire est « le rhizome », que j’emprunte à Gilles Deleuze et à Félix Guattari (1976). Le rhizome m’est utile pour rendre compte des multiples portes d’entrée dans la formation discursive de l’enfant téléspectateur, du déplacement comme chercheuse à l’intérieur de celle-ci, et des figures qui se forment par l’articulation du discours et des pratiques entreprises à son égard. Ce faisant, je propose une archive d’époque de l’enfant téléspectateur du Chili « post-1990 ». Dans celle-ci, je montre des modalités particulières de sa formation discursive et des figures hétéroclites de celui-ci qui ont émergé dans les analyses. Finalement, je présente un ensemble de pratiques discursives qui ont également fait surface dans les analyses. Ces pratiques emploient la figure de l’enfant téléspectateur pour instaurer discursivement d’autres « réalités », qui ne le concernent pas directement. M’appuyant sur Jean-Michel Berthelot (1992), notamment sur son concept d’« opérateur discursif », je qualifie ainsi ces pratiques observées.
