Letting the Right One In: The Formulation & Articulation of a Rights-based Discourse for the International Indigenous Movement

description: At the international level, indigenous activism has increasingly taken the form of advocating for ‘indigenous rights.’ These rights-based claims are articulated through a human rights framework, exemplified by the UN Declaration on the Rights of Indigenous Peoples, which was passed by the UN General Assembly in September 2007. Since this time, the Declaration has become the focal point of indigenous activism at the international – and domestic – levels. Proponents of the DRIP have claimed that it moves international law into a “post-Eurocentric” position, and that for the first time, the rights of indigenous peoples have been recognized by the international community. This thesis interrogates the rights-based discourse employed in international indigenous activism. Using postcolonial and poststructuralist theory, it puts forward a hypothesis of double-movement governance affecting indigenous peoples throughout the world. In this thesis, the double-movement is made up of relations between biopolitical management of indigenous lives, and neoliberal governmentality, which come together to establish the power relations within our present-day colonial system. This double-movement governance is then connected to Glen Sean Coulthard’s critique of a politics of recognition framework, on which human rights are based. Together, this theory forms my hypothesis that instead of providing indigenous peoples with emancipatory pathways out of the colonial present, indigenous rights discourses further entrench colonial norms and hierarchies within indigenous communities, and between States and indigenous peoples. Having established my hypothesis, I then test it with empirical data from the Declaration, indigenous fora at the UN, and domestic laws, agreements and policies. Taking the evidence into account, I argue that despite meaningful steps being taken to establish collective rights for indigenous peoples, a rights-based discourse does indeed continue to entrench colonial norms and hierarchies within indigenous communities and between States and indigenous peoples. This is in part because of issues of translation that occur when indigenous claims are articulated through a human rights framework, but also because a system based upon a politics of recognition – such as a human rights framework – is unable to move indigenous peoples out of the present-day colonial relations of power in which they live. Ultimately, such a system is only able to offer indigenous peoples ‘white liberty and white justice.’
Experimental evaluation of heat transfer and pressure drop performance of internally finned tubes.
Creators: name: Rizvi, S. Tanweer H.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1978
Subjects: subject: Engineering, Mechanical.

description: Heat transfer and pressure drop measurements were made on three test tubes, a quintuplex tube, and two single finned tubes. The single finned tubes tested were of the high spiral type. The spiral finned tubes have been arbitrarily classified in the literature as low spiral with fin height to inside diameter ratio r < 0.065, and as high spiral with the ratio r ≥ 0.065. Lubricating oil was used as the test fluid. Three sets of test runs were performed on each of three test sections, fixing the values of the oil inlet temperature and water flow rate in each set, while varying the oil flow rate to cover as much as possible a wide range of operating conditions. Effects of oil inlet temperature and cooling water flow rate on the performance of test tubes were also investigated. At almost the same operating conditions it was found that the quintuplex finned tube provides a sizable decrease in heat transfer area, but at the expense of high pumping power requirement. It is, therefore, suggested that quintuplex tube should be preferred in industrial applications in which the size of the heat exchanger is an important factor. But if the pumping power is the criterion for selection, the single-finned tube is superior.

description: Pax7 is a paired box transcription factor expressed by all satellite cells which are critically required for muscle regeneration and growth. The absolute requirements of Pax7 in the maintenance of the satellite cell pool are widely acknowledged. However the mechanisms by which Pax7 executes muscle regeneration or contributes to satellite cell homeostasis remain elusive. We performed cell and molecular analysis of Pax7 null satellite cells to investigate muscle stem cell function. Through genome wide studies, we found that genes involved in cell cell interactions, regulation of migration, control of lipid metabolism and inhibition of myogenic differentiation were significantly perturbed in Pax7 null satellite cells. Analysis of satellite cells in vitro showed that Pax7 null satellite cells undergo precocious myogenic differentiation and have perturbed expression of genes involved in the Notch signaling pathway. We showed that Notch 1 is a novel Pax7 target gene and by using a genetic approach we demonstrated that ectopic expression of the constitutively active intracellular domain of Notch1 (NICD1) in Pax7 null satellite cells is sufficient to maintain the satellite cell pool as well as to restore their proliferation. Instead of differentiating into myogenic cells and in the absence of a myogenic cue, NICD1 Pax7 null satellite cells become a source of ectopic brown fat within muscles and give rise to brown adipocytes both in vivo and in vitro. In conclusion we showed that Notch 1 partially rescues Pax7 deficient satellite cells loss and proliferation. Additionally we provide the first evidence that Notch signalling contributes to satellite cell fate by inhibiting terminal myogenic differentiation and inducing brown adipogenesis.

description: Shy children often have difficulty communicating; however, it is not clear whether these difficulties stem from a skills deficit or from an anxiety-driven performance deficit. Therefore, the present study examined how shy children’s communication skills differed from those of average, non-shy children, using the Internet as a medium for social communication. It was hypothesized that shy children may be more reticent than average children to initiate conversation in a novel situation. However, over time shy children were expected to become more comfortable in discussions with their on-line partner and to become less anxious as they acknowledge the anonymity of chat groups. This study also investigated potential changes in negative effects associated with shyness over time. Fifteen shy children (Mean shyness score=72.3; SD=6.43) and 15 average children (Mean shyness score=53.7; SD=5.6) participated in the 10 MSN conversation groups. Children were also given a series of questionnaires prior to and after the 10 sessions. Results from this study suggest that shy children communicate in a similar manner to their average partners when online. Results also suggest that shy children had higher levels of social anxiety than average children before beginning an online conversation with an unknown partner. However, by the end of the 10 sessions, their anxiety had been significantly reduced. No other changes or differences in psychological functioning were noted between shy and average children.

description: This study investigated certain aspects of the cross-cultural adaptation process of Afghan returnees who have repatriated from Iran to Afghanistan. The study’s particular focus is the issue of cross-cultural adaptation in the current context of Afghanistan; that is, what challenges face Afghans returning from Iran to their country of origin following years of exile in Iran. Afghan immigration to Iran has a long history. Using Young Yun Kim’s cross-cultural adaptation theory as the leading theoretical framework, the researcher investigated the cultural adaptation of those who have lived in Iran for more than 10 years and have repatriated voluntarily to Afghanistan at least three years before the data for this thesis were gathered. Semi-structured interviews were conducted for collecting primary data from participants for the thesis. Twelve young returnees from Kabul City, aged 18 to 40, volunteered to take part in the interviews. Results revealed that language barriers, cultural knowledge and environmental challenges were some of the dominant difficulties that returnees experienced after their repatriation. Furthermore, the findings showed that the three main strategies used by the young returnees to adapt to their unfamiliar, new environment of Kabul City included social interaction, using mass media, and keeping an open mind on current issues. The findings of the interviews revealed the ongoing changing nature of identity formation of the returnees after their repatriation to Afghanistan and, also the majority of participants (9 out of 12) voiced a strong sense of belonging and attachment to Afghanistan.

description: Purchase behavior and preferences for consumers of fresh apples were investigated using a consumer survey conducted at a special-event apple market. Survey respondents were asked to list apple cultivars they had purchased at the retail market and the special-event market. The special-event market offered many uncommon cultivars packed in clear plastic bags with a fixed weight and price. Respondents were also asked to identify their reasons for selection of each apple cultivar and answer demographic questions. A total of 169 customers completed the survey. Profiles of customers were identified using multiple correspondence analysis (MCA) and hierarchical cluster analysis (HCA), and the impact of the change in available apple cultivars on consumers’ purchase behavior was explored. Consumers primarily indicated four main reasons in the selection of their apples: visual appearance, previous experience, taste/aroma, and texture. The first two reasons, evaluated before eating an apple, were loaded on the first MCA dimension, while the last two reasons (i.e., eating quality) were loaded on the second dimension in data from both marketplaces. HCA identified five classes of customers in both markets, and results indicated that similar market segments existed within the two marketplaces, regardless of the availability of apple cultivars.

description: This mixed methods study aimed to provide some validity evidence for the use of the ESL sociopragmatics test developed by Roever, Elder and Fraser (2014) for formative purposes. The test developers recommend further validation of the tool, originally developed for the Australian context. In this study, the test items were used to reveal areas of weakness in sociopragmatic knowledge in a group of learners of an academically oriented English Intensive Program in Canada. Analysis of the test scores revealed a lack of knowledge of norms of appropriateness and politeness in English, which was further targeted with an instructional unit informed by the items of the test. Two weeks after the instructional unit was delivered, the participants were asked to complete a follow-up questionnaire. The questionnaire results provided insight into the participants’ perceptions of usefulness of the instructional unit. The learners found explicit instruction on ESL sociopragmatics useful for their language learning experience as well as day-to-day interactions in English. Particularly, they claimed to feel more confident communicating in English after receiving explicit instruction on ESL sociopragmatics. They were able to use information from the lesson in situations such as talking to their language instructors, communicating with university personnel, and participating in service encounter interactions. Therefore, the test proved to have potential for developing instructional materials in an academic context. Based on the findings of the study, suggestions on incorporating sociopragmatic competence into the institution’s EAP curriculum were made.

description: This two-study dissertation aimed to develop a comprehensive understanding of mental health need identification, service referral process, availability of services, and type of mental health services in Ontario for children who have experienced maltreatment with a specific focus on childhood sexual abuse (CSA). The first study was descriptive and involved an email questionnaire completed by Directors of Service in each of the 53 Ontario Children’s Aid Societies (CAS). While the primary purpose of study 1 was to inform the sample for study 2, it also provided information about the identification of mental health needs and the referral process to mental health services for children who have experienced maltreatment. Based on the finding that the majority of mental health service referrals are made to community-based psychologists (80%), study 2 was designed to assess the availability, type, and empirical support of treatments provided by Ontario psychologists and psychological associates to children who have experienced CSA. Through the first provincial census of child and adolescent psychology clinicians registered with the College of Psychologists of Ontario, this study addressed the following questions: (1) What are the demographic, work setting, and treatment provision characteristics of these clinicians? (2) Within this population, what is the proportion and distribution of clinicians who provide treatment to children who have experienced CSA?; (3) To what extent do these treatment services map onto empirically-supported treatments (ESTs) for children who have experienced CSA?; and (4) How do clinicians’ demographic, work setting, treatment provision characteristics, and attitudes toward ESTs predict their approach to intervention? Results indicated that clinicians who worked with children who have experienced CSA differed significantly from other clinicians in terms of age, work setting, self-reported theoretical orientation, and clients’ primary presenting problems. Moreover, clinician age, self-reported theoretical orientation, time devoted to clinical training activities, and general attitudes toward ESTs predicted the use of ESTs among clinicians who work with children who have experienced CSA. Limitations and implications for future research are addressed within each study.

description: Depuis plusieurs décennies, on assiste en Iran à un regain d’intérêt pour la Perse ancienne, en particulier pour la dynastie des Achéménides (550-330 av. J.-C). De ce vaste empire qui s’étendait sur tout le plateau iranien jusqu’à l’Inde et qui fut conquis par Alexandre, il ne reste plus que des vestiges parmi lesquels un ensemble d’inscriptions cunéiformes gravées sur la paroi des rochers ou sur les monuments de l’époque. L’étude porte sur les deux grandes périodes historiques où la traduction accompagne l’intérêt porté à ces vestiges: c’est d’abord le moment orientaliste de leur découverte, puis l’Iran moderne des Pahlavi suivi de l’actuel régime islamique. À la faveur du mouvement orientaliste européen, les inscriptions achéménides ont attiré l’attention des archéologues et suscité la curiosité des philologues au XVIIIe siècle et surtout au XIXe siècle. Rédigées simultanément en plusieurs langues (vieux perse, élamite et babylonien), ces inscriptions ont peu à peu été déchiffrées et traduites vers les langues européennes, en particulier vers l’allemand, l’anglais et le français. Jusqu’à une époque récente, elles sont demeurées opaques pour les Iraniens : héritiers de ce brillant empire, ils n’en comprenaient plus les langues. C’est à partir des années 1970, sous l’impulsion du dernier shah d’Iran que débute la traduction systématique de ces inscriptions vers le persan moderne et, plus généralement, des travaux orientalistes sur la Perse ancienne. Le phénomène s’est ralenti au moment de la Révolution islamique (1979), mais il a repris de sa vigueur avec le durcissement du régime des mollahs. Depuis quelques années, le secteur privé de l’édition publie une abondance de traductions vers le persan d’ouvrages sur la période achéménide initialement publiés en Europe. Ces « traductions-retour » remplissent une fonction identitaire et politique en soutenant le courant nationaliste et réformiste contre un régime qui s’efforce d’occulter le passé préislamique de l’Iran.

description: With the ascendency of data and the rise of interest in analytics, organizations are becoming more interested in the use of data to make their business processes more intelligent and reactive. BI applications are a common way that organizations integrate analytics in their processes. However, it can be days, weeks or even months before a manual response is undertaken based on a human interpreting a report. Even when information technology supports automatic responses within an organization, it is often implemented in an ad hoc manner without following a systematic framework. In this thesis, we present a reactive performance monitoring (RPM) framework which aims at automating the link from the analytical (how well is the operational achieving the strategic) to the operational (the particular process steps implemented within an organization that determine its behavior) aspects of businesses to bypass the strategic (the high level and long term goals an organization is trying to achieve) as needed and reduce the latency between knowledge and action. Our RPM framework is composed of an architecture, a methodology, and a rule environment which permits the redaction of rules possessing relevant conditions and actions. In addition, we present an OLAP rule engine which is demonstrated to be effective in our framework where events are streamed in, reacted upon in real-time, and stored in an OLAP database. To develop and evaluate our framework, two case studies were undertaken. The first was done using IBM technologies implementing an application made to identify patients at high risk of cancer recurrence. The second was done using open source technologies. With this second implementation, we created an application that has the goal of informing women from at risk populations of the different stages of pregnancy on a weekly basis.

description: The autosomal recessive disorder spinal muscular atrophy (SMA) causes motor neuron degeneration and muscle wasting, progressing to paralysis and death in severe cases. The disease is caused by deficiency of survival motor neuron protein (SMN) due to deletion or mutation of the SMN1 gene. We seek to develop a protein-based therapy for SMA using an adenoviral vector which encodes a secretable form of SMN fused to a protein transduction domain (PTD) derived from the trans-acting activator of transcription (TAT) from HIV. We generated secretable GFP proteins using transient transfection in mammalian cells and determined that the secretory peptide was inefficient when paired with the native PTD. We generated TAT-GFP proteins in bacteria and observed that the variant TAT3 most reliably tranduced cells in vitro. We did not observe uptake of the therapeutic protein following infection with an adenoviral vector and subsequent secretion of the protein from infected cells.

description: In the "Internet of Things" (IoT), the things will be able to sense, communicate, and interact. They will also exchange data, information and knowledge, and locate themselves and other things that surround them. In order to be able to interact, the things need to recognize that they are in proximity of other things. It is anticipated that the most widespread components of the IoT will be passive radio frequency identification (RFID) tags because they are inexpensive and provide automatic identification. However, passive RFID tags are not capable of performing complex operations, such as proximity detection and localization, which will be required in future networks. In this thesis, we describe existing problems with current RFID systems and survey potential solutions for localization and proximity detection. Then we present a new RFID device called "Sense-a-Tag" (ST) that can passively detect and decode backscattered signals from tags in its proximity. There have already been an attempt to use this device for tracking. However, detailed analysis of the performance of the ST especially for proximity detection has not been performed yet. We show that when STs are added to a standard RFID system, the problems of proximity detection and localization with RFID tags can readily be solved. Then we applied ST-based system for identifying people and object interactions. The potential uses of ST as an augmented device for IoT applications are discussed in this thesis. Advantages and limitations of an ST based RFID system have been investigated in details for each application. Results obtained from real experiments illustrate that an ST-based RFID system is feasible for proximity detection applications. In addition, a special software is developed in C\# to process the data and run a localization algorithm based on proximity detection information. The same software has been used for tracking people's activity. Different scenarios have been considered in the experiments. We tried to consider majority of factors that might affect the accuracy in the experiments including: angle and distance between the reader/ST and tags, timing in sending queries, presence of human body, etc. The simulations based on real experiments and results illustrates that an ST-based RFID system can be a realistic solution for proximity detection and localization for Location Positioning systems (LPS) and activity monitoring in future IoT.
Traffic modelling of on-line first person shooter games

Publisher: name: Swinburne
Year: 2024

description: Over the past few decades, there has been a great deal of attention paid to modelling the traffic generated by First-person Shooter (FPS) games. This interest has been motivated by the large growth in on-line gaming, which is now a multi-billion dollar industry. The FPS genre is of particular importance to the network engineering community due to its highly interactive nature. The interest in this genre is based not only on the effectsof the network on playability and user experience of the game, but also on the effects that traffic produced by this genre of games may have on other traffic flowing in the network. In order that network simulation can provide more insightful and useful results for studying the interaction between this game traffic and other classes of traffic, good traffic models are required to be developed. This thesis makes a number of contributions to the state of the art in game traffic modelling and synthesis. We show that currently used models are incomplete in that they do not scale with the number of users , nor do they capture the autocorrelated nature of the traffic, and they do not take into account behaviour of individual FPS games. We address each of these matters. In particular, a general model for FPS game traffic during the game-play phase is presented. The development of this traffic model was based on measurements of traffic produced by seven popular FPS games. This model, which is based on the Ex-Gaussian and Gamma Modified Gaussian mixture distributions, is novel and computationally simple and it can be scaled to model scenarios with a large number of game participants without having to conduct and collect data from large numbers of controlled experiments. Since this is a computationally simple model, it is ideal for use as the basis of either a hardware or software based traffic generator that can be used to synthesise representative FPS game traffic. This model is an improvement over previous models, as it also incorporates the serial autocorrelation that exists in the packet traffic that flows in the server-to-client direction by using a simple ARMA time-series approach. A traffic generator based on this model has also been developed for use with the OMNet++ simulation software. This traffic model can be used by Internet Service Providers (ISPs) and the network engineering community to investigate network performance issues, arising from scenarios where FPS games and other applications interact and what techniques are likely to be successful in minimizing their impact on each other.

description: The overall intention of this report is to understand our uOttawa Library staff readiness to provide RDM services. Shifting Horizon II was the fourth in a series of annual uOttawa Library events dedicated to research data management (RDM) awareness-raising and training. Conclusions regarding RDM readiness are derived from information gathered during the registration process as well as results from a post event evaluation survey for the event. This year focused on institutional capacity building by upskilling Librarians, research facilitators, faculty IT representatives and research administrators and support staff. This report has shown that the event catalyzed a nascent community of practice at uOttawa, which also reaches out to include those senior-level administrators from funding agencies, Library, OVPR and Central IT who were in attendance. Preliminary recommendations are made for future RDM training needs and opportunities for Librarians, with some consideration to the needs of other research support staff working in RDM-related services and departments beyond the Library.

description: When compared to traditional concrete, steel fibre reinforced concrete (SFRC) shows several enhancements in performance, including improved tensile resistance, toughness and ductility. One potential application for SFRC is in columns where the provision of steel fibres can improve performance under axial and lateral loads. The use of SFRC can also allow for partial replacement of transverse reinforcement required by modern seismic codes. To improve workability, self-consolidating concrete (SCC) can be combined with steel fibres, leading to highly workable SFRC suitable for structural applications. Recent advances in material science have also led to the development of ultra-high performance fibre reinforced concretes (UHPFRC), a material which exhibits very high compressive strength, enhanced post-cracking resistance and high damage tolerance. In heavily loaded ground-story columns, the use of UHPFRC can allow for reduced column sections. This thesis presents the results from a comprehensive research program conducted to study the axial behaviour of columns constructed with highly workable SFRC and UHPFRC. As part of the experimental program, twenty-three full-scale columns were tested under pure axial compressive loading. In the case of the SFRC columns, columns having rectangular section and constructed with SCC and steel fibres were tested, with variables including fibre content and spacing of transverse reinforcement. The results confirm that use of fibres results in improved column behaviour due to enhancements in core confinement and cover behaviour. Furthermore, the results demonstrate that the provision of steel fibres in columns can allow for partial replacement of transverse reinforcement required by modern codes. The analytical investigation indicates that confinement models proposed by other researchers for traditional RC and SFRC can predict the response of columns constructed with SCC and highly workable SFRC. In the case of the UHPFRC columns, variables included configuration and spacing of transverse reinforcement. The results demonstrate that the use of appropriate detailing in UHPFRC columns can result in suitable ductility. Furthermore, the results demonstrate the improved damage tolerance of UHPFRC when compared to traditional high-strength concrete. The analytical investigation demonstrates the need for development of confinement models specific for UHPFRC.

description: Macrocyclization is a synthetically challenging step in the total synthesis of natural products. The success of chemical approaches such as the Corey-Nicolaou, Yamaguchi and Keck macrolactonization is heavily based on the confirmation and stereochemistry of the substrate. While there have been some advances in computational modeling, it has been difficult to predict whether the above-mentioned reactions will work. We have begun characterizing polyketide thioesterase catalytic activity and substrate tolerance to find more efficient and dependable routes towards macrolactonization and macrolactamization.

description: This position paper intends to stimulate a profound rethinking of contemporary agricultural practice. We criticise the current intensity of chemical plant protection in Germany as ecologically unsustainable and thus threatening the achievement of key targets of environmental protection and nature conservation policies. In the first part of the paper, we provide background information on the use of plant protection products (PPP) in German agriculture, the role of agricultural policy, European pesticide legislation, the principles of and framework for environmental risk assessment and risk management of PPP, as well as environmental effects of PPP. The second part is presented against the backdrop of the European "Sustainable Use Directive" (2009/128/EC). This directive requires that "Member States shall adopt National Action Plans to set up their quantitative objectives, targets, measures, and timetables to reduce risks and impacts of pesticide use on human health and the environment and to encourage the development and introduction of integrated pest management and of alternative approaches or techniques to reduce dependency on the use of pesticides." Reflecting on the corresponding debate in Germany, we suggest the following five key principles for a sustainable use of PPP and provide recommendations for their implementation: (1) minimising use; (2) identifying, quantifying, and communicating risks; (3) optimising risk management; (4) compensating for unavoidable effects; (5) internalising external costs. © 2018, The Author(s).

description: Background: Mycobacterium avium subspecies paratuberculosis (MAP), a member of the mycobacteriaceae family, causes Johne’s disease in ruminants, which resembles Crohn’s disease (CD) in humans. MAP was proposed to be one of the causes of human CD, but the evidence remains elusive. Macrophages were reported to be the only cell where MAP proliferates in ruminants and humans and is likely the major producer of TNFα-associated inflammation. However, whether human dendritic cells (DCs), another major antigen-presenting cell (APC), have the ability to harbor MAP and disseminate infection, remains unknown. Methods: Human monocyte-derived dendritic cells (moDCs) were infected with MAP and phagocytosis and intracellular survival were quantified by immunofluorescence (IF) and colony counts, respectively. MoDC cytokine expression was measured via ELISA and their activation state was measured via flow cytometry. Results: We showed that MAP can infect and replicate in human moDCs as means to evade the immune system for successful infection, through inhibition of the phago-lysosome fusion via the secretion of protein tyrosine phosphatase PtpA. This mechanism initially led to a state of tolerance in moDCs and then subsequently caused a pro-inflammatory response as infection persisted, characterized by the upregulation of IL-6 and TNFα, and downregulation of IL-10. Moreover, we showed that moDCs have the ability to phagocytose up to 18% of MAP, when exposed at a multiplicity of infection of 1:1. Conclusion: Infection and subsequent proliferation of MAP within moDCs could provide a unique means for the dissemination of MAP to lymphoid tissue, while altering immune responses to facilitate the persistence of infection of host tissues in CD.

description: Introduction: Adolescents often face unique challenges during labor and birth. Utilizing the support of a birth doula has been suggested as a beneficial intervention for this vulnerable population. However, existing literature on the efficacy of doula support for adolescents is limited. Additionally, there is a gap in understanding how doula education can better prepare doulas to support adolescent clients. This qualitative study aimed to explore the experiences of doulas providing care to adolescents and their preparedness to support this specific population.
Methods: Through semi-structured individual interviews with five doulas from the Birth Partners volunteer doula program, data was recorded and analyzed thematically.
Results: The findings revealed six major themes: (1) motivation for doula service, (2) primary methods of doula support, (3) obstacles to doula support, (4) preparation for providing adolescent support, (5) lack of emotional preparedness among adolescents, and (6) recommendations for increased support of adolescents.
Conclusion: The findings of this study suggest that doula training programs should include a more comprehensive overview of best practices to support adolescent clients. This tailored training should include approaches to offering physical and emotional support to meet the needs of this population. Although findings are limited, this study is an important contribution to the literature and includes the firsthand experiences of doulas who have engaged in doula care of adolescent clients.
Descriptive Representation of Indigenous Peoples and Democracy in Contemporary Latin America: A Comparison of Indigenous Peoples in Bolivia, Ecuador, Guatemala, and Peru

description: This thesis seeks to expand research on the effects of descriptive representation in Latin America in the case of indigenous parties. Further, the thesis examines the argument that indigenous parties in Latin America have produced a greater support for and satisfaction with democracy in indigenous populations through descriptive representation. Ultimately, I find that indigenous parties that have occupied both the presidency and the national legislature present strong evidence to support the claim in regard to increased satisfaction with democracy; those that have only established presence in the national legislature support the claim in regard to both increased satisfaction and support. On the other hand, where indigenous parties have only achieved representation at the municipal level there is no difference from the case in which no indigenous parties have developed.

description: The "Berlin Air quality and Ecosystem Research: Local and long-range Impact of anthropogenic and Natural hydrocarbons" (BAERLIN2014) campaign was conducted during the 3 summer months (June-August) of 2014. During this measurement campaign, both stationary and mobile measurements were undertaken to address complementary aims. This paper provides an overview of the stationary measurements and results that were focused on characterization of gaseous and particulate pollution, including source attribution, in the Berlin-Potsdam area, and quantification of the role of natural sources in determining levels of ozone and related gaseous pollutants. Results show that biogenic contributions to ozone and particulate matter are substantial. One indicator for ozone formation, the OH reactivity, showed a 31% (0.82 +/- 0.44s-1) and 75% (3.7 +/- 0.90s-1) contribution from biogenic non-methane volatile organic compounds (NMVOCs) for urban background (2.6 +/- 0.68s-1) and urban park (4.9 +/- 1.0s-1) location, respectively, emphasizing the importance of such locations as sources of biogenic NMVOCs in urban areas. A comparison to NMVOC measurements made in Berlin approximately 20 years earlier generally show lower levels today for anthropogenic NMVOCs. A substantial contribution of secondary organic and inorganic aerosol to PM10 concentrations was quantified. In addition to secondary aerosols, source apportionment analysis of the organic carbon fraction identified the contribution of biogenic (plant-based) particulate matter, as well as primary contributions from vehicles, with a larger contribution from diesel compared to gasoline vehicles, as well as a relatively small contribution from wood burning, linked to measured levoglucosan. © Author(s) 2018.

description: Animal studies have shown that chronic high consumption of saturated fat (SF) leads to hypothalamic inflammation and ultimately, alters appetite control. This has been shown to be partly due to an increase in the activity of the transcription factor Nuclear Factor-κB (NF-κB), a major regulator of the inflammatory response. The goal of the study was to first confirm the association between SF measurements and anthropometric traits, then to determine the association between single nucleotide polymorphisms (SNPs) in the NF-κB1 gene and body mass index (BMI) and waist circumference (WC), and finally, to test the interaction between variants in this gene and dietary SF and circulating saturated fatty acids (CSFA) on these anthropometric traits in young adults. A significant positive association was identified between quartiles of CSFA and anthropometric measurements in the total sample (BMI: p = 0.0003, WC: p = 0.0001) and in South Asians (BMI: p = 0.004, WC: p = 0.01), but only marginally among Caucasians (BMI: p = 0.08, WC: p = 0.051) and East Asians (BMI: p = 0.13, WC: p = 0.053). After correcting for false discovery rate, carriers of the T allele in SNP rs4648022 had higher BMI and WC compared to those with the dominant CC genotype (p = 0.0003 and p = 0.0001, respectively). Among Caucasians, there was a significant interaction between SNPs in the NF-κB1 gene and quartiles of CSFA on WC for rs4648095 (p = 0.002). Thus, certain SNPs in the NF-κB1 gene appear to influence BMI and WC and also to modify the association between CSFA and anthropometric traits.
