Effects of Point Visibility on On-Task Behavior and Preference in the Caught Being Good GameFuste, Yudelkis 23 March 2018 (has links)
The Caught Being Good Game (CBGG) is a classroom management intervention used in schools. The purpose of this study was to evaluate the effects of point visibility on appropriate behavior, to examine the degree to which points earned by the opposing team affected the other team’s behavior, to examine both teacher and student preference for the intervention, the effect of student and teacher choice on appropriate behavior, and to systematically replicate previous research showing the effectiveness of the CBGG relative to business as usual. Consistent with previous research, CBGG increased on-task behavior compared to business as usual. Modest and temporary differentiation was observed between salient and hidden points, with hidden resulting in slightly better outcomes. A unit-price analysis further supported that on-task behavior was higher during the hidden points condition. The teacher and students reported preference for the CBGG, and we expect to see higher levels of on-task behavior during the student-choice condition.

The Use of Behavior Specific Praise and the Caught Being Good Game to Improve Class-Wide BehaviorRhodes, Emily 19 June 2014 (has links)
This study evaluated the relative contributions of behavior specific praise statements (BSPS) and the Caught Being Good Game (CBGG) on class-wide appropriate behaviors and examined teacher use of BSPS and corrective feedback. It also evaluated if changes in class-wide behaviors are maintained during follow-up and generalized to non-target academic periods. Data on teacher use of BSPS were also collected during follow-up and generalization probes to examine if the teachers continued to use BSPS during follow-up and generalize their use of BSPS to non-target academic periods. A multiple-baseline design across classrooms with an ABC sequence was used to evaluate the outcomes of the interventions. The results indicated that BSPS was sufficient in two classrooms to increase class-wide on-task behavior for over 90% of students just by explicitly giving attention for appropriate behaviors while the third classroom required implementation of CBGG which provided external reinforcers. Some evidence of generalization and maintenance was observed in all classrooms. All teaching staff's use of BSPS increased during implementation of the BSPS phase, but BSPS use decreased in follow-up, and support for generalization is lacking.

Effekter av oxazepam på fiskbeteende: en metaanalys av studier på vildfångad fisk.Johansson, Amanda January 2022 (has links)
Excreted pharmaceuticals are leaking out into aquatic environments via effluent water where they are hypothesized to be potent enough to alter fish behavior. Central for this hypothesis is oxazepam, an anti-anxiety drug that have been shown to make fish behave more bold, more active, and less social. However, some laboratory trials have also failed to find these effects and have been poor predictors of fishes’ behavior in situ. The aims of my meta-analysis were; i) investigate the strength of oxazepam induced behavior changes in wild-caught fish, and ii) assess eventual impact of citation bias (i.e., that researcher prefer citing studies showing effects) on published literature relating to oxazepam induced behavior changes. I found, when combining existing literature on oxazepam impact on wild caught fish behavior, that exposure concentrations ranging between 0.5-100µg/L, did only change the activity (increased) of the fish. In high (>100 µg/L) concentration exposures activity and boldness increased, and sociality decreased as previously suggested. I also noticed a significant citation bias, where studies showing effects of oxazepam on behaviors were more frequently cited. Several studies report absence of behavior effects caused by oxazepam in controlled laboratory trials, despite using >1000 times higher concentrations that ever been measured in fresh water. Therefore, I find it unlikely that this drug has strong effects on fish in nature. Citation biases towards studies showing effects seems likely to have had a strong influence on the current notion that oxazepam is altering fish behavior.

An analysis of cricket umpiring decisions during the 2007 Cricket World CupMarshall, Dayle Lyn 23 February 2010 (has links)
Cricket umpiring is demanding. In today’s world where so much technology is available to television viewers, they expect perfect umpiring, forgetting that what they see on their television screens is not available to the umpires standing in the middle of the field making the decisions. This study aimed to examine cricket umpires on-field decisions during the 2007 ICC Cricket World Cup. Examining leg before wicket (LBW) and caught behind decisions, in particular. The researcher made use of a notational analysis program known as Umpirestat to collect the necessary data on each umpire. The umpires were examined in two groups Elite and International umpires (groupings defined by the ICC) and were compared to a base line in the form of Hawk-Eye for LBW decisions and TV replays for caught behind decisions. The umpire groups were compared to each other and then to the base line, an individual umpire comparison was then done within each grouping. The data was statistically analysed using percentages, chi squared and modelling for the Elite Umpires. For LBW decisions there was a difference of 2.02% between Elite and International umpires, showing a similarity between the two groups. The difference between Elite Umpires and Hawk-Eye was 18.83% and between International umpires and Hawk-Eye was 16.81%, showing difference between the three groups. It was found that there was a difference of 3.63% for caught behind decisions between Elite and International umpires, showing a similarity between the two groups. The difference between Elite Umpires and TV replays was 2.99% and between International umpires and TV replays there was 0.64%, showing similarities between the three groups. In conclusion, for LBW appeals there is a similarity between Elite and International umpire groupings however a difference exists between Hawk-Eye and both groupings of umpires. For the individual umpires LBW comparison the following was seen for the International umpires; no real conclusions could be drawn due to limited amounts of data collected on them. However, variances in individual performances were seen within the International umpire grouping. For Elite Umpires, it is clearly seen in the model that the umpires expected number of dismissals got closer together and almost group together at around four appeals. This indicates a strong consensus amongst umpires when dealing with four, five and six appeals during a match. This consensus is more pronounced for four and five appeals. In conclusion, for caught behind appeals there is a similarity between Elite and International umpires as well as a similarity between replays and both groups of umpires. For the individual umpires caught behind comparison the following was seen for the International umpires; as with the LBW results there was limited amount of data available for the caught behind results. Thus no real conclusions could be drawn for International umpire caught behind decisions, although when examining the percentage data, differences can be seen. For the individual umpires caught behind comparison the following was seen for the Elite Umpires, no consensus is seen between the umpires - they all appear to have different expected dismissals to one another.

EmbarcaÃÃes a vela do litoral do Estado do Cearà construÃÃo, construtores, navegaÃÃo e aspectos pesqueiros / Vessels sailing the coast of Cearà State building, builders, navigation and fisheries issuesMiguel Savio de Carvalho Braga 27 February 2013 (has links)
CAPITULO 1 â Perfil dos carpinteiros artesanais de embarcaÃÃes a vela do litoral do estado do CearÃ
No contexto mundial, durante o sÃculo XV, a construÃÃo naval das embarcaÃÃes veleiras passaram por evoluÃÃes que propiciaram o empreendimento de grandes viagens. Chegando ao Brasil iniciou-se um longo processo de interaÃÃo construtiva das embarcaÃÃes locais com o conhecimento europeu. As jangadas inicialmente construÃdas sem velas evoluÃram e se propagaram por todo o nordeste e, principalmente no Cearà como embarcaÃÃo de pesca artesanal, evoluindo das jangadas de troncos Ãs atuais de tÃbuas, assim como ocorreu evoluÃÃo construtiva artesanal das canoas e botes. O litoral cearense foi percorrido no perÃodo de setembro de 2010 a maio de 2012, identificando-se in loco os tipos de embarcaÃÃes construÃdas, e localizando e entrevistando construtores artesanais de embarcaÃÃes a vela, foco principal deste trabalho. Foram entrevistados 36 carpinteiros de comprovado reconhecimento local, que responderam questionÃrio estruturado com perguntas direcionadas diretamente à identificaÃÃo do construtor artesanal, seu perfil profissional e da sua arte construtiva, permitindo registros fotogrÃficos, filmagens e gravaÃÃes. Os dados de cada questionÃrio foram transcritos para planilhas eletrÃnicas e analisadas, combinando com as gravaÃÃes de entrevistas transcritas e das filmagens. A pesquisa constatou a baixa escolaridade dos carpinteiros artesanais entrevistados, com 44% de alfabetizados e 42% de analfabetos; a inexistÃncia de qualquer registro construtivo empregado; mÃdia de idade; media de tempo de trabalho e frequÃncia da distribuiÃÃo do tempo de trabalho entre os carpinteiros entrevistados; influÃncia e origem do aprendizado e ausÃncia de enquadramento funcional destes jà que nÃo se aposentam como construtores artesanais. Resultados importantes foram obtidos sobre o perfil do carpinteiro artesanal cearense, considerados importantes para a manutenÃÃo da tradiÃÃo cultural de suas tÃcnicas aplicadas à construÃÃo de embarcaÃÃes a vela, e que compÃem o patrimÃnio histÃrico e socioeconÃmico do estado.
CAPITULO 2 â A construÃÃo dos diferentes tipos de embarcaÃÃes a vela do litoral do estado do CearÃ
As embarcaÃÃes a vela sÃo usadas na pesca desde a Idade MÃdia e foram introduzidas no Brasil no inÃcio do descobrimento. No CearÃ, a frota veleira à constituÃda por jangadas, paquetes, canoas e botes, e este estudo objetivou descrever os aspectos e processo construtivos destas embarcaÃÃes, e verificar a existÃncia de diferenciaÃÃo entre localidades quanto aos custos, tempo de construÃÃo, materiais, ferramentas manuais, posicionamento dos mastros com os tipos e tamanhos de vela e elaboraÃÃo de planos de linhas. A metodologia constou de levantamentos de dados in loco, no perÃodo de maio 2010 a dezembro de 2012, com entrevistas com 36 carpinteiros artesanais em 25 localidades de praia de dezoito municÃpios, e aplicaÃÃo de questionÃrios e registros por gravaÃÃo, fotografia e filmagem. O mÃtodo construtivo adotado pelos construtores à o do âesqueleto primeiroâ, ao qual os diversos componentes sÃo acrescentados. O principio para a construÃÃo dos botes triÃngulo e bastardo à o mesmo adotado por toda a forÃa de trabalho, que sÃo idÃnticos no aspecto construtivo e de estrutura de casco, diferem no tipo de mastro e vela, tendo o bastardo um mastro fixo com vela latina bastarda e o bote triÃngulo vela latina triangular. Os custos de construÃÃo variam em ordem decrescente para botes, jangadas, canoas e paquetes, determinados pelo comprimento da embarcaÃÃo e tipo de madeira. Pontualmente, registrou-se em Bitupità a existÃncia da vela quadrangular latina, denominada de âvela quatro punhosâ, envergada em mastro bastardo nas canoas de curral.
CAPITULO 3 â A navegaÃÃo praticada por mestres marcadores nas embarcaÃÃes a vela no estado do CearÃ
A orientaÃÃo praticada a bordo de embarcaÃÃes veleiras para navegaÃÃo e pesca utiliza referÃncias de terra para compor as linhas de posiÃÃo denominadas caminho e assento que, ao se cruzarem, determinam o local desejado. Esta atividade vem acontecendo desde a existÃncia da jangada de piÃba e se perpetua por transmissÃo entre geraÃÃes. O estudo foi desenvolvido com mestres marcadores de trÃs localidades, Baleia, Fortaleza e Redonda, onde predominam canoas, jangadas e botes, respectivamente. A prÃtica desta modalidade de navegaÃÃo à idÃntica para os diferentes tipos de embarcaÃÃo e diferem pouco entre as localidades estudadas. O exercÃcio da orientaÃÃo exige que o mestre marcador tenha boa visÃo e memÃria para encontrar caminho e assento, alÃm de sofrer restriÃÃes na ausÃncia da luz solar. Essa atividade à iniciada pelos marcadores ainda na juventude, e esses conhecimentos sÃo adquiridos independentes do grau de instruÃÃo e se consolidam tanto pelo exercÃcio da pesca quando pela experiÃncia adquirida. A observaÃÃo de estrelas e planetas revela a direÃÃo do caminho de volta ao porto de origem tendo a estrela do porto vÃrias denominaÃÃes no litoral cearense. A falta de visibilidade do litoral, ocasionada por chuva, cerraÃÃo ou outros fatores, interfere negativamente na identificaÃÃo de pontos de referÃncia existentes no litoral. A marcaÃÃo terrestre vem sendo gradativamente substituÃda pelo uso do GPS na localizaÃÃo dos pesqueiros mais produtivos, com grande aceitaÃÃo pelos mais jovens. O baixo preÃo e eficiÃncia comprovada desse equipamento tÃm justificado sua difusÃo ao longo de todo o litoral do CearÃ.
CAPITULO 4 â EmbarcaÃÃes a vela do litoral do estado do CearÃ, distribuiÃÃo espacial da frota e da produÃÃo pesqueira
O Cearà possui 573 km de litoral, distribuÃdo por 20 municÃpios costeiros e conta com 113 localidades de pesca estuarina e marinha. Este estudo se baseia nos seguintes dados estatÃsticos do Programa ESTATPESCA a- composiÃÃo da frota por tipo de barco e municÃpio; b- produÃÃo de pescado por tipo de barco e municÃpio; c- produÃÃo das principais espÃcies de peixe por tipo de embarcaÃÃo. Foi feita a descriÃÃo das caracterÃsticas das embarcaÃÃes a vela do Cearà de uma forma mais detalhada que as dividiu em jangadas ocada e de isopor; paquetes ocado e de isopor; canoa de Paracuru; canoa de Moitas-Baleia; canoa de Camocim (bianas); Canoa de Acarau-PreÃ-BitupitÃ; canoas de currais de BitupitÃ; canoa-paquete de Fleixeiras-Guagiru e botes triangulo e bastardo. Os resultados mostram que os paquetes sÃo maioria numÃrica e com maior distribuiÃÃo geogrÃfica, destacam-se pela versatilidade, por serem leves para encalhe e movimentaÃÃo na faixa de praia, pela necessidade de pequena tripulaÃÃo e baixo custo de construÃÃo e manutenÃÃo. Os botes tÃm a menor abrangÃncia territorial, com o bastardo bem concentrados em Camocim e o triÃngulo com maior concentraÃÃo em IcapuÃ. A canoa tem predominÃncia exclusiva no litoral oeste e a jangada, no litoral leste. Em termos relativos, as embarcaÃÃes participaram da captura nas seguintes proporÃÃes: canoas = 45,3 %; paquete = 22,3 %; botes = 22,4%, destacando-se os municÃpios de Camocim, Itarema, Icapuà e AcaraÃ. Estes tÃm produÃÃo mais seleta, capturando espÃcies de maior valor comercial, a saber guaiÃba, cavala, pargo, sirigado, carapitanga e dourado. As jangadas vÃm perdendo importÃncia relativa na captura do pescado, mas ainda com destaque para os municÃpios de Fortaleza, Aquiraz, Beberibe Cascavel e Aracati. / CHAPTER 1 â Profile of the artisanal carpenters of sail crafts in Cearà State
In a worldwide scenario, during the XV Century, the naval building of sail craft underwent an evolutionary development that enabled the undertaking of long-length voyages across the oceans. By arriving at Brazil, an intensive interaction process between local sail boat construction and that of European-derived knowledge. The sail rafts, at first built without sail, were deployed over the whole Brazilian northeast, mainly in Cearà State, as artisanal crafts, evolving from simple dugouts to the actual wooden ones as well as canoes and rowboats. For this research work, the Cearà Stateâs coast was surveyed from September, 2010 to May, 2012, taking in situ stock of all types of constructed crafts, and pinpointing and interviewing artisanal builders of sailboats, who are than main target population of this survey. To this aim, 36 accomplished carpenters, locally recognized as such, were required to answer a number of questionnaires directed toward a full appraisal of the artisanal naval builders, its professional profile and handicraft, for which photographic records, pictures and sound recordings were obtained. The derived data were transferred to electronic spreadsheets and then analyzed by crosschecking the recorded interviews and the movie pictures. This survey led to the following results: occurrence of low reading ability by the artisanal carpenters so that 44 per cent were found to be illiterate; non-existence of any kind of professional registration by the competent public offices; mean age of 22.1 years; high mean working time and frequency of distribution among the sampled population; factors of influence and origin of learning techniques and absence of functional framing, since they to do not retire as naval builders. Significant results were got as to the artisanal carpentersâs profile in Cearà State, which were deemed quite relevant for the maintenance of the folklore of their techniques applied to the construction of sail crafts, and round up the historic and socioeconomic heritage of the Cearà Stateâs coastline .
CHAPTER 2 â Construction of different types of sail craft along Cearà Stateâs coastline
The sailboats are used in fisheries since the middle ages and were introduced in Brazil at the beginning of its discovery. The Cearà Stateâs fleet is made up of rafts, canoes and boats whose study was meant for describing aspects of the building process and for ascertaining the existence of differentiation among fishing communities as to costs, construction time, basic materials, hand tools and positioning of masts according to boat size, sail types and setting of lining patterns. The methodology consisted of data surveys carried out locally, in the period from May, 2010 through December, 2012, by means of interviews with 36 artisanal carpenters in 25 fishing sites of 18 costal counties, by applying questionnaires and data gathering by recording, photography and movie pictures. The constructive technique consists of mounting a âprimary skeletonâ to which all other component parts are attached. The building principle of the triangle and bastard boats is the same as adopted by the whole of the labor force, which are identical as to their constructive pattern and hull framework, but differ as to the types of masts ands sails, namely the bastard one having a fixed mast and a storm jib, and the triangle one having a triangular storm jib. The construction costs vary in a decreasing order for boats, rafts and canoes, as determined by the craft length and kind of timber. Somewhat exceptionally there was identified in BitupitÃ, Barroquinha county, the existence of a square storm jib named âfour-fist sailâ, bent up as a bastard mast in the fish-weir canoes.
CHAPTER 3 â The navigation practiced by master position markers on board sail boats in Cearà State
The orientation carried out on board sailboats for navigation and fishing makes use of landmarks in order to compose the position lines named pathway and outpost that, while intercrossing, determine the sought after site. This activity has been taking place since the very early existence of the sail raft and it endures itself from generation to generation. This study was undertaken by master markers in some fishing localities, namely Baleia, Fortaleza and Redonda where canoes, sail rafts and boats are respectively predominant. The practice of this kind of navigation is similar for the various types of boats and diverges from one another very little among the studied landing points. The exercise of orientation requires that the master marker has got good eyesight and memory in order to find out the pathway and the outpost, besides undergoing setbacks from the absence of sunlight. That activity is started when the fisherman is still young, and his long-lived expertise is acquired independently of the educational degree as it is derived from both the fishing chores and the accumulated experience. The observation of stars and planets reveals the way back to the home port whose identifying star receives many nominations along Cearà Stateâs coastline. The lack of visibility brought about by rain, clouding, and other factors meddle with the identification of conspicuous landmarks. This age- old technique has been gradually replaced by the use of GPS devices for pinpointing the most productive fishing grounds, with a high degree of acceptance by the young generation. The low purchase price and the proved efficiency of that equipment has accounted for the diffusion of their advantages among the fishing communities of Cearà State.
CHAPTER 4 â Sail crafts in Cearà Stateâs coastline: fleet and fishing production spatial distribution
The Cearà Stateâs coastline spreads over 573 km distributed by 20 coastal counties, and 113 estuarine and marine fishing communities. This study is based on the following statistical data gathered through the ESTATPESCA Program: fleet composition by types of boat and county; fish production by type of boat and county; catch composition of the main fish species by type of boat. A detailed description of the sailboats in Cearà was presented in order to provide information on a number of variants of their main types, namely hollow raft, styrofoam-fulled rafts, canoe from Paracuru, canoe from Moitas-Baleia; canoe from Camocim; canoe from AcaraÃ-PreÃ-BitupitÃ; canoe from Bitupità fish-weirs, canoe-raft from Fleixeiras-Guagiru, triangle boat and bastard boat. The results show the small raft holds a numeric majority and a wider geographic distribution, standing out by being lighter to anchor on the beach sand, requiring fewer crew, and entailing lower construction and maintenance costs. The boats show a narrower territorial range, with the bastard ones being concentrated in Camocim county and the triangle ones more frequent in Icapuà county. The canoe and the large-sized raft hold an outstanding predominance on the western and the eastern sides of Cearà Stateâs coastline, respectively. In relative terms, the main types of fishing craft took part in the caches according to the following proportions: canoes = 45.3 per cent; small raft = 22.3 per cent; boats = 22.4 per cent. Among their home counties stand out Camocim, Itarema, Icapuà and AcaraÃ, the ones that boast a more exclusive fish production made out of such species as yellowtail snapper, king mackerel, Caribbean red snapper, black grouper, dog snapper and dolphin. The large-sized rafts have shown of late a tendency for playing a lesser part in fish catching, but they are still relevant in such Cearà Stateâs counties as Fortaleza, Aquiraz, Beberibe Cascavel and Aracati.
