A Content Analysis of Newspaper Reports on School Violence in Trinidad and Tobago

Harris, Charlene, Dunkley, Lisa R. 15 November 2018 (has links)
Although violence in schools has received increasing attention in the media in Trinidad and Tobago over the past decade, the limited existing data on school violence is concerning. The present investigation utilizes newspaper articles from the three main newspaper outlets as textual data to explore the framing of school violence in Trinidad and Tobago. Research shows the manner in which the media report on school violence influences public perceptions, gives rise to particular attitudes and can influence decisions by policymakers (Jacobs, 2014). This investigation aims to assess for school violence using the question: How is school violence portrayed in print media in Trinidad and Tobago. Specifically, we will examine: 1) the characteristics of these reports on school violence in print media and 2) the similarities and differences between print news sources related to school violence. The exploration of these research questions will provide a framework for exploring how findings on school violence may impact public perception and subsequent prevention of school violence in Trinidad and Tobago.

A tool to assess nutrition and physical intervention for school-aged children

Mitchell, Samantha Nicole 15 April 2011
Over the last two decades the incidence of overweight and obesity among children and adolescents has reached epidemic proportions in both developed and developing nations. Reducing the incidence of childhood overweight and obesity is of particular importance in countries undergoing social and cultural transitions, such as Trinidad and Tobago, where chronic diseases, such as childhood obesity may have severe social and economic impacts on public health. Although there are a number of studies that have investigated the health and lifestyle behaviours of school aged children, very little information exists about health and lifestyle behaviours of school age children in Trinidad and Tobago. Also, little information exists on the development of questionnaires to address health related issues within this culture and age group. The purpose of this study was to describe the development and pre-test of a knowledge, attitude, belief and practice (KABP) questionnaire to assess healthy lifestyle outcomes of school aged children in Trinidad and Tobago. Three data sources were used for the design and pre-testing of the questionnaire: content analysis of the literature, interview of key stakeholders, and onsite observations. An in-depth review of the literature was conducted for insights about questionnaire development. Interviews (individual and focus groups) were conducted of key stakeholder groups (school staff, the national school feeding program and curriculum officers) and children to determine current policies and practices, beliefs, barriers, and attitudes towards promoting health lifestyles (nutrition and fitness) in Trinidad and Tobagos elementary schools. Site observations provided insight into the school food environment, class room practices, and food services offered at school. Observations were recorded using field notes and interviews were tape recorded and transcribed verbatim. Interview data from each participant was analyzed separately for dominant themes and recurring topics. The interviews were then compiled to establish the main issues which the questionnaire needed to address. The KABP questionnaire addressed general knowledge about healthy eating and activity, screen time, physical activity, snack and food choices, and self efficacy. The KABP questionnaire consisted of question items that were developed to fit the issues unique to Trinidad and Tobago, and items from previously validated questionnaires which were modified to fit the context of Trinidad and Tobago. The questionnaire was then pre-tested with a sample group of the target population. Pre-testing was done one-on one, in small groups and in the classroom setting. Based on pre-test results the questionnaire was then modified to form version 1.0 of the KABP questionnaire. Version 1.0 of the KABP questionnaire consisted of 30 questions divided into four categories. This culturally sensitive age appropriate questionnaire was the foundation of the KABP questionnaire which was used to collect baseline, midpoint and endpoint of the larger project.

Structural framework and its influence on the Quaternary-age sequence architecture of the northern shelf of Trinidad and Tobago

Punnette, Stefan Wayne 23 December 2010 (has links)
The North Coast Marine Area (NCMA) extends across ~7000 km2 of the northern Trinidad and Tobago shelf in water depths between 50 to 200 meters. In 2009 the NCMA had two exploration blocks under active oil and gas exploration with gas production from the NCMA totaling ~ 1.1 tcf since 2002. All natural gas discovered to date in the NCMA has been interpreted as biogenic although one previous worker has speculated that a minor component of thermogenic gas is also present. The NCMA is located within a complex tectonic environment characterized by oblique strike-slip displacements between the Caribbean and South American plates at a rate of about 20 mm/yr. The main faults of the 200-km-wide plate boundary zone include: 1) the El Pilar right-lateral strike-slip fault zone to the south on the island of Trinidad and the Gulf of Paria which GPS results indicate to be largely inactive; 2) the North Coast fault zone (NCFZ) which coincides with the southern boundary of the Tobago basement terrane and appears to be slightly active with down-to-the-north, Miocene to recent oblique-slip movements on the NCFZ producing accommodation space for deposition of sediments along the northern shelf of Trinidad and Tobago; and 3) the Hinge Line fault zone (HLFZ) crossing through the NCMA and forming the focus of Chapter 2 of this thesis. The ~120 km long Hinge Line fault zone has an average east-northeast strike approximately parallel to the GPS-derived plate motion direction (080°), and is a subvertical, thick-skinned right-lateral strike-slip fault. Localized zones of transpression and transtension form locally where the trace of the fault deviates from the 080° direction of pure, right-lateral shear and these localized areas of complex faulting and folding provide important structural traps for Pliocene and Miocene gas reservoirs in the NCMA north of the HLFZ. Growth sequences along the HLFZ indicate that the fault activated in Miocene time and continues to up to the late Pleistocene (~500 k.y.) and in some areas forms active scarps on the seafloor. Structural maps and isochron maps were made for four horizons underlying the northern shelf of Trinidad including top Mesozoic basement, top Miocene, top Pliocene and seafloor. These maps support a change in terrigenous source area for the northern shelf of Trinidad: during the Miocene and early Pliocene, terrigenous sources were coming from the southeast through the Atlantic Ocean; during the mid-Pliocene to present the source area changed to the southeast through the Gulf of Paria. The shallow seismic stratigraphic study of Chapter 3 analysed two Pleistocene fourth-order shelf and shelf-edge stratigraphic sequences deposited over the past ~500 k.y in the western part of the NCMA. New micropaleontologic data tied to a well through the two sequences B and C constrain the initial deposition of each sequence ~450 k.y (Sequence B) and ~260 k.y. (Sequence C). The lithologic well log shows that the sequences are sand, shale, and thin limestone. Seismic interpretation allows division of sequences B and C into eight system tracts which include: 1) lowstand system tracts, 2) transgressive system tracts, 3) highstand system tracts and 4) falling stage system tracts. Two lowstand systems tracts in sequences B and C are characterized by delta plain deposition of the Orinoco Delta with a north-eastward terrigenous source direction coming from the western side of Trinidad, through the Gulf of Paria. The falling stage systems tract of sequence C consists of a suite of ~20 – 45-m-high, 0.1° – 0.25°-inclined, and north-eastward-prograding muddy, shelf deltaic clinoforms marking the paleo-shelf edge. Fault controls penetrate into Sequence B and may have produced accommodation space but do not penetrate into overlying Sequence C which therefore must have been eustatically controlled. These Pleistocene sequences may provide a more recent analog for Miocene and Pliocene age sequences and reservoirs that form the highly productive horizons of the NCMA gas field. / text

Proveniencia Sedimentaria del Grupo Península Trinidad, Península Antártica. Similitudes con el Complejo Duque de York, Patagonia

Castillo González, Paula Alejandra January 2008 (has links)
Este trabajo presenta nuevos resultados sobre la petrografía y geoquímica de las rocas terrígeno-clásticas del Grupo Península Trinidad (TPG), ubicado en la Península Antártica, con el fin de identificar las características de su fuente y del régimen tectónico de su cuenca de depósito y compararlas con las características de la fuente y del régimen tectónico de depósito de las rocas terrígeno-clásticas del Complejo Duque de York (DYC), ubicado en el margen occidental del extremo sur de Sudamérica (Patagonia). Se recolectaron 14 areniscas y 8 lutitas de cuatro localidades donde aflora el TPG, en la costa norte y oeste de la Península Antártica. Con estas muestras se realizaron estudios clásicos de proveniencia sedimentaria, tanto petrográficos (en areniscas) como geoquímicos (en areniscas y lutitas). Para realizar la comparación entre las rocas del TPG y DYC, además de métodos de proveniencia sedimentaria clásicos, se utilizaron redes neuronales artificiales. Las características geoquímicas de las rocas del TPG sugieren que ellas se habrían originado a partir de la erosión de una fuente ígnea común, de composición intermedia a ácida, lo que concuerda con un depósito en una cuenta desarrollada en un margen continental activo. Por otra parte, la composición modal de las areniscas indica una proveniencia de un arco continental disectado, lo que sería compatible con la erosión de las raíces plutónicas de un arco magmático ubicado en un margen continental. Las características geoquímicas de la fuente y régimen tectónico de la cuenca de depósito de las rocas del TPG coinciden con las del DYC, lo que sumado a similitudes geocronológicas, sugieren un marco geodinámico común, es decir, ambas unidades derivarían de un mismo arco magmático, posiblemente ubicado en un margen continental activo. Sin embargo, si esta configuración es correcta, las diferencias petrográficas indican que el DYC correspondería a un depocentro relativamente más antiguo que el depocentro asociado al TPG.

Perception of an Alternative Model for the Vocational Education Program at Secondary Comprehensive Schools in Trinidad and Tobago

Hernandez, Jason F. (Jason Francis) 05 1900 (has links)
This study was designed to compare perceptions of an alternative model for the vocational education program at secondary comprehensive schools in Trinidad and Tobago. The groups compared were vocational education teachers, academic teachers of related subjects, secondary comprehensive principals and vice principals, and vocational education curriculum supervisors. A survey instrument was developed and was tested to ensure its validity and reliability. The instrument utilized a seven-point Likert-type scale to measure the intensity of agreement or disagreement. The items related to the proposed model were subdivided into administration and planning, curriculum and instruction, and evaluation components.

Ludic Caribbean : Cultural Representations of Trinidad in V.S. Naipaul's Fiction / Spielerische Karibik : Kulturelle Repräsentationen von Trinidad in V.S. Naipauls Fiktion

Nickel, Horatiu-Lucian January 2006 (has links) (PDF)
Trinidad, V.S. Naipaul’s native island, is consistently represented in the 2001 Nobel Prize winner’s fictional works, above all in "The Mystic Masseur" (1957), "The Suffrage of Elvira" (1958), "Miguel Street" (1959), "A House for Mr Biswas" (1961), "A Flag on the Island" (1967), "The Mimic Men" (1967), "In a Free State" (1971), "Guerrillas" (1975), "The Enigma of Arrival" (1987) and "A Way in the World" (1994). The present dissertation analyses representations of Trinidad as “play-culture” in the aforementioned writings by initiating a methodological dialogue between postcolonial/cultural studies on the one hand and performance studies, play theory, as well as cultural anthropology on the other hand. The study is divided into three parts corresponding to the three main facets of Trinidad as it appears in Naipaul’s fiction: firstly, as a childish world; secondly, as a festive place and thirdly, as a playground for the western imagination. The image of Trinidad as a childish space stands at the intersection of the autobiographical genre with the colonial/Social Darwinist discourse of the so-called “child races”. In both cases we have to do with a cultural construct of childhood whose main stereotypical features are smallness, imitation, irrationality and of course, playfulness. The second part of the dissertation focuses on the importance of rituals and festivals in shaping up Indian and African identities in Trinidad. Roughly, Hindu rituals are capital means to create diasporic Indias, whereas Carnival is a powerful symbol of the Afro-Trinidadian community. Nevertheless, they carry the potential of becoming genuine liminal spaces, where ethnic boundaries are transgressed. The third section is devoted to a discourse of play as imagination. In this respect, Trinidad appears as an adventure playground where the Westerner projects his/her desires, sometimes under the mask of scientific respectability. The eye of the European sees the tropical island as an exotic Garden of Eden, as an aesthetic space with strong pictorial and theatrical qualities. But if Trinidad occurs as an artistic, a fictional object, then Naipaul’s novels and stories describing it are fiction about fiction, and so have a very important metafictional component. At this stage, since metafiction is also a capital element of postmodernism, I trace back Naipaul’s ludic metaphors to the present-day Zeitgeist, pointing out the postmodern elements in his texts dealing with Trinidad. / Die vorliegende Dissertation, eine Studie zu V.S. Naipauls Darstellung von Trinidad als Spielkultur, untersucht das Bild, das der berühmte, aber auch umstrittene Literatur-Nobelpreisträger von seinem Heimatland durch fiktionale Mittel kreiert. Der Hauptakzent liegt auf Naipauls Romanen und Kurzgeschichtensammlungen "The Mystic Masseur" (1957), "The Suffrage of Elvira" (1958), "Miguel Street" (1959), "A House for Mr Biswas" (1961), "A Flag on the Island" (1967), "The Mimic Men" (1967), "In a Free State" (1971), "Guerrillas" (1975), "The Enigma of Arrival" (1987) und "A Way in the World" (1994); jedoch auch folgende nicht fiktionale Schriften, die Trinidad erwähnen, werden in Betracht bezogen: "The Middle Passage" (1962), "The Loss of El Dorado" (1969), "Between Father and Son: Family Letters" (1999), "The Overcrowded Barracoon and Other Articles" (1972), "The Return of Eva Peron with The Killings in Trinidad" (1980), "Finding the Centre" (1984), "Reading & Writing" (2000) und "The Writer and the World" (2002). Der diskursive Ansatz ist der gemeinsame Nenner einer interdisziplinären Methode, die sowohl kulturwissenschaftliche und postkoloniale Fragestellungen, als auch anthropologische und ludistische Konzepte in sich vereint. Mithilfe dieses Ansatzes wird bewiesen, dass das Trinidadbild in Naipauls Schriften nicht eine objektive Widerspiegelung der “Wirklichkeit”, sondern ein soziokulturelles Konstrukt ist, das aus “kulturellen Repräsentationen” (“cultural representations”) besteht.
