With the fear of decline of the Cape Breton fiddling tradition after the airing of The Vanishing Cape Breton Fiddler by the CBC in 1971, both the Cape Breton community and ethnographers clamored to preserve and maintain the extant practices and discourse. While this allowed for performance contexts and practices to burgeon, it also solidified certain perspectives about the “diasporic preservation” and resultant “authenticity.” This work aims to trace the seeds and developments of the beliefs surrounding the Cape Breton fiddling tradition, from the idealizations of Enlightenment Scotland to the manipulation and commercialization of the folklore and Celticism of twentieth-century Nova Scotia. These contexts romanticized older practices as “authentic,” a construct that deeply impacted the narrative about the Cape Breton fiddling tradition. One of the most rooted and complex concepts in this narrative is that of “old style,” a term that came to represent the idealized performance practice in post-1971 Cape Breton fiddling. As models were sought for younger players to emulate, pre-1971 “master” fiddlers with innovative stylistic approaches began to be identified as “old style” players. The interstices of the tradition allowed more extreme stylistic experimentation to be accepted as “traditional,” while the symbiotic social practice of dancing necessitated relative conservatism. Analysis will show that “listening” tunes fell into the interstices of allowable innovation, while dance (particularly step-dance) tunes demanded certain “old style” techniques. A more holistic view of the complexities of the Cape Breton fiddling tradition follows from a perspective not only of the socio-musical elements that shaped the historical narrative, but also of the musical elements of this dance-oriented “old style.” / Arts, Faculty of / Music, School of / Graduate

The original intention of this thesis was to study the opinions and activities of the Maritime colonies during the War of 1812, in an attempt to explain the colonies' almost neutral position throughout the hostilities. The Maritime attitude has already been explained in terms of economic ties binding the colonies' interests with those of New England. This thesis was therefore directed by a desire to ascertain whether or not such economic interests constituted the dominating influence in Maritime policy or whether there existed equally important influences of a political and social nature. The conclusion attributes Maritime reaction in 1812 to a combination of economic, political, and social factors shaping the colonies' activities during the preceding twenty years. In the course of defining these factors, however, the emphasis shifted from the war itself to the preceding two decades which emerged as a period of experiment and adjustment—a period of confused adolescent fumbling toward the larger powers and responsibilities of adulthood. Into the midst of these struggles the War of 1812 was projected, to be greeted by the Maritimers as an interruption meriting attention only in so far as it could contribute to their provincial interests. In this thesis, therefore, the War of 1812 is presented as but the epilogue illustrating the trend of Maritime interests and policy during the period 1790-1810. It is not the intention of this thesis to view Maritime history strictly in terms of a cyclical development paralleling the human life cycle. However, the contradictory character of the Maritime scene during this period, as the colonies see-sawed between dependency and self-sufficiency in their claims, resembles the confusion of adolescence and the title of Colonial Adolescence was chosen for lack of a better description of this transitional phase. In the study of the Maritime colonies' transitional struggles, this thesis seeks to illustrate how the social-economic complex of a community moulds and is reflected in its political life. Although the period 1790-1814 was one of isolation and individualism for the colonies, the majority of Maritime communities faced similar problems in their struggles for stability and identity. Geography had rendered them an economic unit; the British administration had endowed them with similar political organizations; and settlement had produced similar social problems. This thesis, therefore, treats its subject in terms of basic economic, political, and social situations as they were faced in the Maritimes, with whatever variations each colony might offer. The three chapters dealing with these situations constitute the core of the thesis. In the first chapter an attempt has been made to set the scene of British politics and administration, for it was in this context that the colonies pursued their objectives influenced at all times by the changing fortunes of British politics. The study throughout tends to concentrate upon the mainland colonies of Nava Scotia and New Brunswick, partly because the developments of this period were centered here, since Prince Edward Island remained a backward variant; and partly because the nature of sources dictated such an approach. Research was concentrated mainly upon the Colonial Office records pertaining to Maritime affairs during this period. These included the official correspondence passing between the Colonial Office and the colonial governors, in which the policy of the British administration and its colonial deputies is outlined and colonial reaction commented upon. Also included were the journals of Assembly and Council, shipping statistics, petitions and memorials from individuals and associations in the colonies reflecting something of colonial opinion, needs and activities. These records were supplemented by secondary sources, drawn upon for an outline of British and North American activities and policies; to a more limited extent colonial newspapers and private papers provided contemporary comment on the Maritime scene—but the Maritimers do not emerge from these researches as an articulate lot. / Arts, Faculty of / History, Department of / Graduate

In this condition, pedagogical advice emerges as an important function, intending to build teaching knowledge in collective, permanent and institutionalized spaces of formation. Therefore, the contexts of curricular innovation defining the outline of this work are revealed as insurmountable elements to the research, referring to the Bologna Process focusing on Portugal, and to Universidade Nova focusing on Brazil. In this scenario, the question that guided this research was: Which University Pedagogical Advisory has been built and how is its work structured in the context of curricular innovation? We aim to identify its role in the delimited contexts and understand how they have been self-trained to manage the demands placed upon them, regarding the consolidation of innovative curricular models. Pursuing the objective, we defined a method we called Mapping with Focused Study, under qualitative approach. The Mapping aims to broadly describe data related to the object, providing a panoramic, descriptive and contextual view, while the Focused Study seeks the meanings attributed to the object by the subjects, in an interpretative dimension. Data analysis was performed by units, aimed at an integrated construction of knowledge about the object, observed in both ... (Complete abstract click electronic access below) / Doutor

Background: College students experience food insecurity at a rate 3.5 times higher than the U.S. general population, affecting 43% of students. Furthermore, college students consume high amounts of ultra-processed products. NOVA, a food classification system, takes into account food processing and is thought to better fit the modern food environment. Purpose: The purpose of this research project was to examine the impact of CalFresh enrollment on food security status. This study also evaluated the impact of two different nutrition education interventions (MyPlate and MyPlate+NOVA) on participants’ dietary habits and nutrition knowledge. Methods: Food security, dietary habits, and nutrition knowledge were assessed at baseline, three-month, and at six months follow-up. Food security status was measured using the USDA 6-item Short Form Food Security Assessment Module. A 12-week mobile nutrition education intervention providing MyPlate or MyPlate+NOVA nutrition messages was implemented, and dietary habits were assessed using an adapted NHANES 2009-2010 dietary screener questionnaire, while nutrition knowledge questions were created from the nutrition education messages. Results: Food insecurity decreased by approximately 63% among CalFresh participants. There were no differences in dietary habits or nutrition knowledge among any of the intervention groups or the control group.

[pt] A percepção dos processos migratórios como problema de segurança nacional, principalmente a imigração irregular, levou à adoção pelos Estados de regulamentações que desrespeitam direitos e garantias fundamentais. Identificados e classificados como os outros ou inimigos que ameaçam a ordem social, os imigrantes em condição de irregularidade migratória são transformados em objetos de um discurso criminalizador não apenas nos debates públicos e políticos, mas também na legislação. O reforço preventivo de medidas de segurança na legislação americana e europeia depois dos ataques terroristas do ano 2001 nos Estados Unidos, deu origem ao fenômeno da convergência entre a Lei Penal e a Lei de Imigração, com o surgimento do termo “Crimigração”. Nesse contexto, o presente trabalho tem por objetivo o estudo da relação imigração-segurança, referenciando primeiramente como o conceito do Direito Penal do inimigo e o surgimento da percepção global do imigrante como o “outro”, influenciou fortemente na criação da legislação americana e europeia, de prevenção da imigração ilegal. Assim, a presente pesquisa também analisa como o Chile não é alheio a este fenômeno e, como em outros países, adotou a mesma lógica mencionada anteriormente em sua nova lei de migração. Essa nova lei, aprovada, no ano de 2021, embora considerada, no papel, um avanço no cumprimento dos padrões internacionais de proteção aos direitos, na realidade, perpetua condições de exclusão para os migrantes, com uma forte orientação para o fechamento de fronteiras, baseando-se na criminalização da imigração. / [en] The perception of migratory processes as a national security issue, especially irregular immigration, has led to governments adopting regulations that disrespect fundamental rights and guarantees. Identified and classified as the others or enemies who threaten social order, immigrants in condition of migratory irregularity are transformed into the targets of a criminalizing discourse, not only in public and political debates, but also in legislation. The preventive reinforcement of security measures in American and European legislation after the terrorist attacks in 2001 in the United States, gave rise to the phenomenon of convergence between Criminal Law and Immigration Law, with the emergence of the term Crimigration. In this context, this paper aims to study the immigration security relationship, considering first how the concept of Criminal Law of the enemy and the emergence of the global perception of the immigrant as the other strongly influenced the creation of American and European legislation aimed to prevent illegal immigration. Furthermore, the present research analyzes how Chile is not disconnected from this phenomenon, but like other countries, has adopted the same logic mentioned above in its new migration law. This new law, passed in 2021, although considered on paper an advance in the fulfillment of international standards for protection of rights, in reality it perpetuates conditions of exclusion for migrants, with a strong inclination towards the closing of borders, based on the criminalization of immigration.

<p>The astrophysical ³⁰P(<em>p</em>,<em>γ</em>)³¹S reaction rate is a key quantity used in both classical nova and type I X-ray burst models that predict isotopic abundances produced during nucleosynthesis in the outburst. Currently, uncertainties in ³¹S structure parameters lead to a variation in the reaction rate by a factor of 20 at nova temperatures causing predicted isotopic abundance ratios in the Si-Ar mass region to vary by factors of up to 4. The ³⁰P(<em>p</em>,<em>γ</em>)³¹S reaction rate can be determined indirectly by measuring transfer reactions populating excited states in ³¹S. Nuclear structure information for ³¹S resonant states above the proton threshold of 6131 keV and within the Gamow window that contribute most significantly to the reaction rate can be used to re-evaluate the rate for nova and type I X-ray burst temperatures and reduce current uncertainties. We have performed an experiment in order to study the level structure of ³¹S via the ³²S(<em>d</em>,<em>t</em>)³¹S single-nucleon transfer reaction using the MP tandem accelerator and Q3D magnetic spectrograph at MLL in Munich, Germany. Excited states of ³¹S in the 6-7 MeV region were observed and spin-parity constraints have been suggested. In this work we describe the experimental setup, data analysis and results for both experiments and provide recommendations for further investigation of the ³⁰P(<em>p</em>,<em>γ</em>)³¹S astrophysical reaction rate.</p> / Master of Science (MSc)

High ultra-processed food (UPF) consumption is associated with weight gain, obesity, metabolic syndrome, cardiovascular disease, all-cause mortality, and type 2 diabetes. "Food agency" refers to an individual's food preparation attitudes and capabilities within a given social and physical food environment. Although there is an association between the ability to prepare certain dishes and higher cooking frequency with lower UPF intake, it is still unclear if cooking and food agency influences UPF consumption due to the lack of research in this area. To date, studies of food agency have not included detailed dietary analyses. This cross-sectional study included 40 adults (73% female, aged 39±15 years, body mass index [BMI] 25.8±4.9 kg/m2) and aimed to determine the relationship between food agency and UPF intake. Food agency scores were calculated using the validated Cooking and Food Provisioning Action Scale (CAFPAS). Cooking behaviors and frequency were also collected. Dietary intake was assessed using three 24-hour dietary recalls with each item categorized by degree of processing using the NOVA classification system. Analyses included one-way ANOVAs between CAFPAS score quartiles [Q] and Pearson correlations between CAFPAS, cooking behaviors, and dietary intake. UPF intake was calculated in percent total calories and percent total grams to account for artificial sweeteners and other low calorie products that may be classified as UPFs. Low food agency was associated with a 14% higher UPF intake (% total calories) compared to high food agency (P=0.03). There were no differences between CAFPAS quartiles and UPF intake in % total grams. When age was divided into three categories, UPF intake was significantly lower in older adults (60+ years) compared to adults aged 19-39 years and 40-59 years by 26.4% and 29.1% respectively (P=0.02). When analyzed using bivariate analysis, lunch (r=-0.482, P=0.002) and dinner (r=-0.385, P=0.014) cooking frequency, frequency of cooking a meal from scratch or fresh ingredients (r=-0.320, P=0.044), and CAFPAS self-efficacy (r= -0.369; P= .019) were negatively correlated with UPF intake (% total kcal). These findings provide support for the possibility of reducing UPF intake through cooking interventions aimed at improving components of food agency such as problem solving, skills to create a meal from what is available, and cooking confidence. Future studies should include a larger, heterogeneous population to provide more insight into dietary differences between levels of food agency and expand the diversity of research in this area. / Master of Science / High ultra-processed food (UPF) consumption is linked to weight gain, obesity, metabolic syndrome, cardiovascular disease, all-cause mortality, and type 2 diabetes.
