In four experiments, pigeons performed on schedules of food reinforcement across two different contexts. One context consisted of having the operant chamber fully illuminated, with increased noise levels, and reflective aluminum foil draped over the chamber sidewalls. This context was paired with oral injections of water. Another context consisting of having the chamber dark except for response keylight and at ambient noise levels was paired with oral injections of ethanol. Ethanol dosages were determined by using a dose that doubled the average variable-ratio postreinforcement pause. These procedures established the dark context as a conditioned stimulus capable of producing Pavlovian conditioned tolerance to ethanol. This tolerance was expected to be context specific to the dark context. At the same time the reinforcement schedule produced a learned compensation or tolerance for the ethanol that would not be limited to one context. Tolerance was defined here in behavioral terms: a variable-ratio (VR) schedule of reinforcement with high rates of responding and little or no pausing after food delivery, similar to behavior following water delivery but in this case, after ethanol delivery. To test the efficacy of the context specific tolerance relative to the reinforcement-schedule-acquired-tolerance, probes were conducted. These consisted of delivering ethanol while the context predicted water. The results indicated that most subjects displayed tolerance that was not context specific. However, for a minority of subjects, the acquired respondent tolerance was highly context specific, being present only in ethanol paired context. In explanation, those subjects who displayed context specific tolerance also tended to have more behavioral disruption from smaller doses of ethanol than other subjects. This subset of subjects showed more sensitivity to ethanol. At the higher doses, Pavlovian tolerance may have been hindered by the prolonged systemic effects of the ethanol. The same dosages allowed for more intoxicated practice and enhanced the learned tolerance from the reinforcement schedule. The implications of this research point to additional studies of how and why tolerance to the behavioral effects of a drug is acquired.

In September 2002, the Canadian Institute of Health Information, Health Canada and the National Task Force on Health Information created the Canadian Community Health Survey (CCHS) whose objective was to determine the status of the Canadian health care system and the health status of Canadians themselves. The CCHS was divided into two cycles (Cycle 1.1 and Cycle 1.2) of which CCHS Cycle 1.1 was general population health survey designed to provide information for 136 health regions covering all provinces and territories. For this particular report, data from Cycle 1.1 was analyzed in order to determine if Work stress, Type of Smoker, Body Mass Index (BMI) and Household Income were significant factors contributing to the general health of the population of Ontario. Each of the above mentioned variables was considered individually for a given age, gender and marital status of the respondents. Logistic Stepwise Regression was used to determine if these variables were significant predictors of general health and all the possible two way interactions were explored at the five percent level. Furthermore, a diagnostic check of the fitted models was conducted and the validity of the models was assessed once again after removing the influential points. In addition, the linearity of all the continuous variables was tested in the logit models followed by a comparison of the fitted models using weights. Overall, it was found that all of the potential predictor variables of concern were significant predictors of general health. The majority of two way interaction terms were included in the fitted models, however, the overall fit of some models was found to be poor. In some cases, upon removing the influential points, the overall fit improved significantly, while for others, the fit did not improve by much. Also, it was found that Household Income and Work stress were not linear in the logit model while Age was found to be linear. Upon comparing models with and without sampling weights, it was found that the model that included sampling weights consisted of the same main effects as the model without sampling weights, along with additional interaction terms which were not present earlier.

Abstract Vårt syfte med studien är att kunna bidra med kunskap om hur vårdnadshavare och förskolepersonal upplever kommunikationen när det kommer till samverkan och deras egna tankar kring samarbetet mellan hem och förskola. När det kommer till respondenternas egna tankar så kan det vara exempelvis lösningar som fungerat väl och strategier som fungerat mindre bra. Samt kan det innefatta hur förskolepersonalen tänker kring läroplanen för förskolan (Lpfö18) och hur den är närvarande i arbetet. Vi skapade kvalitativa enkäter till både förskolepersonalen och till vårdnadshavarna som vi skickade ut via Google forms, svaren kom sedan in och datorn sammanställde dem till oss. Därefter analyserades svaren och vi jämförde de sinsemellan, vilka likheter samt olikheter det fanns kring samverkan ur bådas perspektiv. I resultatdelen framkommer det att för att samverkan ska fungera väl krävs det en tydlig dialog och kommunikation med vårdnadshavare och hem från förskolepersonalens håll. Vilket vi fått erfara ur våra enkätsvar och det krävs att personalen har en god kännedom om vilka kommunikations redskap som vårdnadshavarna eftersöker för att informationen ska nå ut till alla. Digitalsamverkan kommer även att belysas i resultatdelen, vilket både hem och de i verksamheten ansåg vara viktigt samt vilka former den gärna bör delas ut i. Den valda teorin i arbetet blev det sociokulturella perspektivet som vi använde oss av vid analys och begrepp som kommunikation, interaktion och dialog vid samspel kom att spela stor roll.

A agenda de pesquisa da discriminacao condicional e composta por diversos procedimentos que investigaram a formacao de classes de equivalencia. Dentre eles: o procedimento Go/Nogo com estimulos compostos; o procedimento Yes/No; o procedimento Respondent-type; o procedimento de pareamento de estimulos envolvendo uma resposta (Stimulus Pairing Response); e o procedimento de pareamento de estimulos envolvendo uma resposta de orientacao (Stimulus pairing Orientation Response). No Respondent-type a condicionalidade entre os estimulos nao foi demonstrada em treino, mas sim por meio do desempenho dos participantes em condicoes de testes das relacoes emergentes. A condicionalidade nao poderia ser demonstrada por respostas diferenciais aos pares de estimulos relacionados em condicoes de treino, uma vez que nenhuma relacao R-S r foi programada. Apesar de nenhuma resposta ser requerida nessas condicoes, existem respostas que naturalmente ocorrem frente ao ambiente programado (e.g respostas sensoriais) e que sao relevantes para o desempenho nas tarefas, no caso, os testes. Em contingencias de controle de estimulos, respostas sensoriais ou de orientacao sao necessarias, primeiramente, por colocarem os participantes em contato com as propriedades relevantes dos estimulos que compoe o ambiente programado. Alem da relevancia por colocar o organismo em contato com as propriedades relevantes dos estimulos, a agenda experimental demonstrou que as respostas de orientacao tambem influenciam na emergencia de relacoes transitivas. Tendo em vista a relevancia das respostas de orientacao, o presente estudo tem como objetivo rastrear medidas da resposta de orientacao por meio do rastreamento dos movimentos oculares de participantes expostos ao procedimento Respondent-type. Explorar medidas da resposta de orientacao em treino sem reforcamento diferencial e testes das relacoes emergentes pode ser uma maneira de contribuir com a investigacao das variaveis de controle dessas respostas e, com isso, permitir a manipulacao de propriedades espaco-temporais eficientes. Apesar das classes serem formadas a partir de treino Respondent-type (sem programacao de R S r), sua demonstracao, em condicao de teste, seria acompanhada pela demonstracao de observacao seletiva? De acordo com os resultados, nove de dez participantes demonstraram a emergencia de classes equivalentes. Assim, a replicacao foi bem-sucedida. Dados obtidos atraves do equipamento de rastreamento dos movimentos oculares permitiram a identificacao de observacao seletiva nos testes em MTS, mesmo nao havendo programacao de relacao R S r em treino. Por fim, a demonstracao de observacao seletiva permitiu a elaboracao de hipoteses baseadas em aspectos do procedimento que permitiram o estabelecimento de funcoes de estimulos corretos e incorretos na tarefa experimental (uma vez que o treino das relacoes condicionais nao era um treino discriminativo) / Conditional discrimination literature studies the formation of equivalent classes through several different procedures, such as: the Go/No-go procedure with compound stimuli; the Yes/No procedure; the Respondent-type procedure; the Stimulus Pairing Response procedure; and the Stimulus Pairing Orientation Response procedure. Regarding the Respondent-type procedure, the conditionality between stimuli was not demonstrated in training, but it was instead observed in the performance of participants in emergent relations test conditions. Conditionality could not be demonstrated by differential responding in training, since R-S relation was not programmed in this study. Even though no responses are required in these conditions, some responses that naturally occur in the programmed environment (i.e. sensorial responses) are relevant for the performance of tasks, which in this case are the tests. In stimuli control conditions, sensorial or orientation responses are needed, first, to put the participants in contact with the relevant properties of the stimulus that form the programmed environment; and second, to demonstrate that such responses also influence the creation of transitive relations. Considering how relevant orientation responses are, this study aims to track measurements for such responses through tracking the eye movements of participants exposed to Respondent-type procedure. Through the exploration of orientation responses in trainings that lack differential reinforcement, and of tests for emerging relationships, this study can contribute to research investigating the variables of orientation responses, and allow for a manipulation of their spatial-temporal properties. Although classes are formed through Respondent-type training (without an R-S response being programmed into it), would their establishment, in testing conditions, be accompanied by the establishment of selective observing? According to the results, nine in ten participants observed the establishment of equivalent classes, which indicate that our replication was successful. Data obtained through eye-movement tracking allowed us to identify selective observation in MTS training even through no R-S relationship was programmed. Lastly, the establishment of selective observation allowed us to formulate hypothesis based on certain aspects of the procedure, which allowed for the establishment of functions of correct and incorrect stimuli in the experimental task (because the training for conditional relationships was not a discriminative training)

Syftet med denna studie är att undersöka psykisk ohälsa bland högstadieelever utifrån skolkuratorernas perspektiv. De efterfrågade frågeställningarna för denna studie är hur psykisk ohälsa hos elever kan se ut utifrån skolkuratorernas perspektiv, vilka strategier som används för att motarbeta detta fenomen och vilka orsakerna är till psykisk ohälsa. Metoden som användes för denna studie var att intervjua fem skolkuratorer om frågor som berör ämnet psykisk ohälsa bland unga. Resultatet visade att den psykisk ohälsan har ökat de senaste åren och att stödsamtal och föreläsningar används av skolkuratorer som strategi för att motverka psykisk ohälsa bland unga. Utifrån skolkuratorernas utsagor framgick dessa orsaker som var bland annat stress, påverkan av sociala medier, problematiska relationer inom familjen och till vänner, kärleksrelationer samt socioekonomisk utsatthet. Studien beskriver även rollen som skolkurator och kuratorns professionella förhållningssätt gentemot eleverna. Avslutningsvis indikerar resultaten att det är brist på forskning inom det valda området, som kräver mer vidare forskning. / The purpose of this study is to investigate mental illness among high school students from the perspective of school counselors. The questions asked for this study are how the experiences are examined from the school counselors' perspective, what strategies are used to counteract this phenomenon and what the causes are for mental illness. The method used for this study was to implement interview five school counselor questions concerning the subject of mental illness among young students. The results showed that mental illness has increased during recent years and that supportive talks and lectures are used by school counselors as a strategy to counteract mental illness among young people. According to the school counselors' statements, there are reasons such as stress, the influence of social media, problematic relationships within the family and with friends, love relationships and socio-economic vulnerability. The study also describes the role as school curator and the curator's professional attitude towards students. In conclusion, the results indicate that there is a lack of research in the chosen area, which requires more further research.

This diploma thesis is focusing on use of Botanical garden of Faculty of Science, Charles University in Prague by teachers as a destination for class field trips. Teachers use this garden with different objectives and different intensity. This diploma thesis provides a summary of this using by the processing of the survey, which took place in elementary school teachers and high school teachers. This work is testing the following hypotheses: 1. Teachers with length of practice above twenty years use the field trip less than teachers with length of practice under twenty years. 2. Men use guided tours more than women. 3. High school teachers use geopark for tour more than elementary school teachers. 4. Teachers with length of practice above twenty years visit gardens other than Faculty of Science, Charles University in Prague and the Botanical Garden in Prague Troja less than teachers with length of practice under twenty years. The thesis summarizes basic information about the field trip as an organizational form. The thesis also deals with the Botanical Garden of faculty of science Charles University in Prague, its collections, history, and possibilities of using in schools.
