No. of bitstreams: 0 Previous issue date: 2011-04-20Bitstream added on 2014-06-13T18:41:32Z : No. of bitstreams: 1 larosa_g_dr_arafcf.pdf: 673974 bytes, checksum: 4d2ce27e8e4be82a1d47bbc38eabfa9c (MD5) / Universidade Estadual Paulista (UNESP) / O objetivo deste trabalho foi elaborar um produto cárneo a partir da CMS de tilápia-do- Nilo contendo os antioxidantes naturais: alecrim, orégano, sálvia e moringa e o antioxidante sintético propil galato, visando sua utilização como recheio ou acompanhamento da refeição. As degradações químicas e microbiológicas constituem os principais fatores de deterioração dos alimentos, sendo a oxidação um dos mais importantes processos de degradação por gerar sabores e odores desagradáveis. Como forma de prevenir ou retardar a oxidação, são adicionados ao alimento substâncias antioxidantes, e os condimentos têm demonstrado certo poder antioxidante, oferecendo uma alternativa ao uso de antioxidantes sintéticos. A composição centesimal, avaliação microbiológica e análise sensorial foram realizadas no início e final do armazenamento e, periodicamente foram determinados TBARS, BNVT, pH, cor instrumental e contagem de microrganismos psicrotróficos. Os resultados mostraram que os diferentes antioxidantes influenciaram o índice de oxidação lipídica e os valores de pH durante o período de armazenamento da CMS. Os valores de pH ficaram compreendidos entre 6,17 e 6,55 e os valores iniciais de malonaldeído foram semelhantes no início e a com orégano apresentou a menor oxidação (0,158 mg de MDA.kg-1 ), a qual foi acompanhada pela que continha sálvia (0,186 mg de MDA.kg-1 ). A maior oxidação, neste período, foi verificada para a CMS sem antioxidante, e o alecrim e moringa foram os antioxidantes naturais menos efetivos. Os valores da intensidade de vermelho (a*) para as CMS elaboradas sem antioxidante e com alecrim não apresentaram alterações durante o armazenamento e os valores de BNVT (11,41 a 12,35 mgN.100g-1 ) não foram alterados com os condimentos. Considerando o efeito dos antioxidantes x armazenamento os recheios apresentaram valores diferentes de pH quando... / The aim of this study is to evaluate the efficiency of oregano, sage, moringa and rosemary as natural antioxidants and propyl gallate as artificial antioxidant used in stuffed food made with minced fish of tilapia and stored frozen for 120 days. Chemistry and microbiological degradations are the main causes of food deterioration, and oxidation is one of the most important process of degradation because it can generate unpleasant flavor. Lipid oxidation is one of the most important alterations that affect both oils or fats and foods that contain them, as a way to prevent or retard oxidation, antioxidant substances are added in the food. The condiments have demonstrated antioxidant activity and offer an alternative in order to replace synthetic antioxidants. Protein, fat, moisture and ashes determination, microbiological analysis and sensory evaluations were conducted in the beginning and the end of storage period. TBARS, BNVT, pH, instrumental color and psychrotrophic microorganism count were determined periodically. The antioxidants interfered in pH (6,17 and 6,55) and TBARS values during 120 days under freezing (-18 o C). The lowest TBA values were found for oregano (0,158 mg de MDA.kg-1 ) and sage (0,186 mg de MDA.kg-1 ). The stuffed food made with minced fish of tilapia, without antioxidant, had the most oxidation, and sage and moringa were not good source of antioxidant. Red color (a*), in products with rosemary and control, and BNVT values (11,41 - 12,35 mgN.100g-1 ) were not altered. The lowest pH value was found for the product with sage (6,20), but similar to the moringa and propyl gallate, while oregano and rosemary showed the highest values (6,63 and 6,29), at 5 days of storage. Microbiological analyses were in accordance with Brazilian legislation. Sensory evaluation indicated that the panelists preferred the formulations made with oregano and propyl gallate. The results showed ... (Complete abstract click electronic access below)

Considerando a importância do lúpulo na produção de cerveja, principalmente seu alto teor de compostos considerados bioativos, por exemplo as procianidinas, a lupulagem a frio pode ser uma notável fonte de melhoramento nos aspectos sensoriais da cerveja, assim como no conteúdo de compostos com possíveis benefícios à saúde. Primeiramente, foi analisada a atividade antioxidante, pelos métodos de DPPH e ABTS, de sete variedades de lúpulo (Cascade, Fuggle, Tradition, Saaz, Centennial, Herkules e Magnum), com a finalidade de escolher uma para ser utilizada na lupulagem a frio. O Cascade foi selecionado para utilização na lupulagem a frio, principalmente por ser o atualmente o lúpulo mais produzido e consumido mundialmente. A produção das cervejas se diferenciou apenas na etapa da maturação, onde ela foi dividida em 17 recipientes. Cada cerveja maturou sob diferentes temperaturas (de 0 a 10°C), tempos de contato do lúpulo com a cerveja (de 0 a 20 dias) e concentrações de lúpulo (de 1,5 a 3 gL-1), seguindo um delineamento composto central rotacional, com três repetições do ponto central. As 17 cervejas foram analisadas físico-quimicamente em relação ao extrato original/primitivo, extrato aparente, atenuação aparente, teor alcoólico, amargor, cor, pH, turbidez, compostos fenólicos totais e atividade antioxidante (DPPH e ABTS). Foi realizada também uma análise sensorial, avaliando aceitação pela cor, aroma, sabor e amargor, além da aceitação global. As variáveis analisadas durante a lupulagem a frio não apresentaram influência no produto final em relação as analises físico-químicas e a aceitação sensorial. / The growth of craft beer production in Brazil and the consequent use of old production techniques, such as dry-hopping, forgotten by the large companies and little studied, open space for studies to improve these techniques. Considering the importance of hops in beer production, especially their high content of compounds considered bioactive, for example procyanidins, dry-hopping might be a notable source of improvement in the sensorial aspects of beer, as well as in the content of possible healthy compounds. Firstly, the antioxidant activity of seven hop varieties (Cascade, Fuggle, Tradition, Saaz, Centennial, Herkules e Magnum) was analized by DPPH e ABTS, in order to choose one to be used in the dry-hopping. Among the analyzed hops, the Cascade type was selected and, therefore, used during the dry-hopping process, mainly because it is currently the most produced and consumed hop worldwide. The brewing process was the same until the maturation, when the beer was divided into 17 containers. Each beer matured under different temperatures (from 0 to 10°C), time of contact between beer and hop (from 0 to 20 days) and hop concentration (from 1,5 to 3 gL-1), following a central rotational design, with three replicates of the central point. The 17 beers submitted to physicochemical analysis as original/primitive extract, apparent extract, apparent attenuation, alcohol content, bitterness, color, pH, turbidity, total phenolic compounds and antioxidant activity (DPPH and ABTS). A sensory analysis was also implemented, evaluating the attributes: color, aroma, flavor, bitterness and global acceptance. The variables analyzed during dry-hopping did not show any influence on the final product in the physical-chemical analysis and sensory acceptance.

Acceptance and commitment therapy training and psychological flexibility for helping professionals

Kidney, Gillian January 2018 (has links)
This thesis is an exploration of two interconnected areas: Acceptance and Commitment Therapy (ACT) training for helping professionals (HPs) and psychological flexibility in helping professionals. The ACT model holds that HPs need to be psychologically flexible (or, herein, flexible) in order to be effective ACT practitioners, and thus a primary goal of ACT training is to enhance participant flexibility. The first chapter is a systematic review of studies that have evaluated the effectiveness of ACT training. It focused on ACT training practices and outcomes related to knowledge, skills, and psychological flexibility in HPs. The results of this review suggested that ACT training can be effective in providing HPs from a range of occupational background with the necessary knowledge and competency to deliver ACT interventions. Furthermore, ACT training can increase HP flexibility. However, confidence in these findings is limited due to methodological weaknesses, particularly variability in ACT training practices, inconsistent use of available measures, a lack of psychometrically robust measures to assess ACT knowledge, and the absence of a flexibility measure designed for use with HP populations. Recommendations were made regarding future research needs in this area, including the development of a HP-specific measure of flexibility. The second chapter reports on the development and initial validation of a measure designed to assess flexibility in the specific context of professional helping, called the Mindful Healthcare Scale (MHS). The results of two studies employing two separates samples of HPs provided good preliminary evidence of the MHS's factor structure and internal validity. The MHS was also found to converge in theoretically-consistent ways with other measures of flexibility and constructs related to the occupational functioning of HPs including burnout syndrome, self-compassion, and empathy. These findings suggest that the MHS may have considerable utility in relation to ACT training for HPs and may also advance our understanding of flexibility's role in HP occupational well-being and functioning.

Psychological acceptance and family quality of life in families of children with intellectual disabilities

Walsh, Allison Jessie January 2014 (has links)
In order to examine the literature on acceptance and mindfulness in parents of children with developmental disabilities a systematic review was conducted. Twelve studies were included in the review and provided some support for the relevance of these concepts in helping to support parents of children with developmental disabilities. However, general study quality was poor and methodological limitations hampered confidence in these findings. Research considerations are discussed. An empirical study was conducted to examine the relationship between psychological acceptance and family quality of life in parents of children with intellectual disabilities. One-hundred and twenty-nine parents of children with intellectual disabilities participated in a questionnaire based study. Participants completed measures of family quality of life, psychological acceptance, emotional adjustment, mental well-being and impact of the child. Parental psychological acceptance was positively associated with family quality of life and was found to account for around 1.9 per cent of its variance. Parental emotional adjustment was also positively associated with family quality of life, however, when parental psychological acceptance was added to the regression model emotional adjustment was no longer a statistically significant variable. The results of this study suggest that parental psychological acceptance may explain some of the variance in family quality of life. Further research is needed to ascertain whether interventions that improve parents' psychological acceptance also improve family quality of life.

Examining Perceptions of Sex Offenders as Influenced by Gender Variations and Rape Myth Acceptance

January 2018 (has links)
abstract: While there is a good amount of research focused on sex offenders as a whole, only a limited number of studies examine variations within these offenders, how people view the variations, and why their opinions may differ. This study focuses on the interconnections among gender norms, rape myth acceptance, and the perception of sex offenders by administering an online student survey. The survey measured rape myth acceptance and adherence to traditional gender roles to see how they affected perceptions of sex offenders. Perceptions were measured using vignettes that were varied by gender and the situation described. Results showed that higher rape myth acceptance would decrease the blameworthiness of the offender, that the offender was seen as more blameworthy when the offender was a male, and that women tended to see the offender as more blameworthy than men did. The type of sexual situation did not have an impact on blameworthiness, nor did adherence to gender roles. The findings support past research that suggests that rape myth acceptance can impact people’s opinions about offenders in sexual situations and specifically that these opinions differ depending on the gender of the offender. With some offenders being viewed as more blameworthy than others, it is necessary to examine sex offense laws to see how they may disproportionately affect some offenders and implement harsher punishments than the public may deem necessary. / Dissertation/Thesis / Masters Thesis Criminology and Criminal Justice 2018

Using Disability Awareness Instruction to Promote Peer Acceptance and Positive Attitudes Toward Students with Disabilities

Gardiner, Margot Caroline 01 March 2016 (has links)
This qualitative study examines the experiences and attitudes of elementary school students regarding individuals with disabilities, following five weeks of disability awareness instruction. It also evaluates the social validity of disability awareness instruction as an intervention tool based on student perceptions, and compares the use of a didactic teaching approach with one that also incorporates the use of bibliotherapy techniques. The current study is part of a larger study using a pre-test, post-test experimental group design (Teerlink, 2012). Participants included 322 elementary school students. Each class of first through sixth grade students was randomly assigned to one of three conditions: a bibliotherapy treatment group (n = 125), a didactic teaching group (n = 124), and a no-intervention control group (n = 73). Data for this study were collected at post-test only, using a short-answer, open-ended questionnaire administered to all participants, as well as focus group interviews conducted with three to four students from each grade level. Results indicate that age and grade level seemed to have a progressively strong influence on whether students knew someone with a disability or recognized the presence of a disability among those with whom they were acquainted. In their attempts to define what it means to have a disability, as well as to identify specific disabilities, student responses seemed to lean towards observable impairments such as Down syndrome, physical disabilities, and speech/language impairments. The overwhelming majority of participants indicated that they would like to be friends with someone who had a disability and that the most important thing they learned from the disability awareness lessons was to be kind and helpful to those with disabilities. Although the majority of students expressed the desire to be friends with people who had disabilities and clearly recognized the importance of treating them with kindness and compassion, students were equally split on whether or not these ideals were actually being implemented by students in their school. In addition, when students were given the opportunity to describe their own observations and examples of how students with disabilities were treated at their school, they were more likely to describe incidents of conflict or unpleasant interactions rather than recalling incidents of kindness or positive interactions. Students specifically identified communication issues and coping with stressful or frustrating situations as the biggest challenges or fears associated with trying to be friends with someone who has a disability. Students from both the bibliotherapy group and the didactic teaching group seemed to share similar attitudes towards individuals with disabilities and respond with equally positive enthusiasm to the intervention. Implications for future research and practice are discussed.

Acceptance and Commitment Therapy for the Treatment of Posttraumatic Stress Among Adolescents

Woidneck, Michelle R. 01 August 2013 (has links)
Trauma exposure among youth in the United States is a common event. Although the number of individuals who meet criteria for a diagnosis of posttraumatic stress disorder (PTSD) is only a small percentage of those exposed to trauma, many individuals who do not meet full criteria for PTSD continue to experience problematic posttraumatic stress symptomology. Acceptance and commitment therapy (ACT) is an empiricallybased psychological intervention that has shown effectiveness in the treatment of a number of concerns among both adults and adolescents. ACT has shown preliminary effectiveness in the treatment of adult PTSD, but its effectiveness in treating adolescent posttraumatic stress is currently unknown. Using a multiple-baseline design, the present study investigated the effectiveness of a 10-week ACT protocol to treat adolescents experiencing posttraumatic stress. Seven individuals between the ages of 12 and 17 participated in the treatment, four of who were from a community sample and three who were in residential care to treat comorbid eating disorders. Structured interviews were completed at pretreatment and individuals reported baseline data for anywhere from 7 to 66 days before engaging in treatment. Symptom and process measures were completed at each session. Postassessment was completed one week following the final session. Results revealed a decrease in posttraumatic stress symptomology across both samples, with a 73.7% mean reduction in self-reported posttraumatic stress symptomology and a mean reduction of 58.8% on clinician-rated measures of PTSD. Overall results provide preliminary support for ACT as an effective treatment for adolescent posttraumatic stress. Empirical and clinical implications of results as well as limitations and future directions are discussed.

Perceived Parental Acceptance Related to Self-Esteem, GPA, Sex-Role Identity, and Substance Use of Adolescents From Intact and Reconstituted Families

Sniteman, Stephen B. 01 May 1993 (has links)
This investigation assessed the relationship between adolescents of intact families and adolescents in reconstituted families with regard to the effects of perception of parental acceptance on the variables of self-esteem, academic performance, sex role identity, and use o f substances. Observed differences between adolescents of intact and reconstituted families from a structural perspective, eliminating process variables, were also examined. Participants included two hundred fifty-six high school students in grades 9 through 12 in an overseas Department of Defense Dependent School (DoDDs) . Questionnaires incorporated the measures of Perception of Parental Behavior Index; Rosenberg's Self-Esteem Survey; The Bern Sex Role Inventory (BSRI); questions on substance use; and self-reported grade point averages (GPA). Major findings include (1) Adolescents living in an intact family (process variables excluded) evidenced significantly higher GPA scores than adolescents residing in a reconstituted (step-family) situation. However, with regard to the use of substances, sex role identification, and self-esteem, no differences emerged. (2) When the effects of parental acceptance were assessed, differences among adolescents of intact families and adolescents of reconstituted families emerged among the variables of femininity, self- esteem, and substance . In contrast, sex role identification, masculinity , self-esteem, substance use , and GPA were not found to be mediated by perception of parental acceptance. The lack of significant differences in self- esteem and substance use contrasted sharply with the findings among adolescents within intact families. (3) When positive perception of parental acceptance was evidenced across eight distinct family compositions of intact and reconstituted families , as opposed to negative perception, self- esteem score s were highest , irrespective of family structure.

MODELING PSYCHOLOGISTS’ OPENNESS TO PERFORMING CLINICAL WORK WITH TELEPSYCHOLOGY

Pierce, Bradford S 01 January 2017 (has links)
This cross-sectional study examined whether the Theory of Reasoned Action (TRA) and Technology Acceptance Model (TAM) apply to psychologists’ openness to using telepsychology, and to identify significant personal or environmental predictors of telepsychology adoption. A total of 1,791 licensed psychologists currently practicing psychotherapy in the United States were recruited to complete a previously developed 21-item pool. Personal and environmental characteristics were also collected. Path models representing the TRA, TAM, and a hybrid of both were tested. Also, a logistic regression was used to identify personal and environmental predictors of current use of telepsychology. Results indicated the TRA and TAM were a poor fit for modeling psychologists’ openness to using telepsychology. Adequate fit was found with a third model in which the perceived attitudes of others concerning telepsychology were associated with the perceived ease of use and usefulness of telepsychology. Perceived ease of use and usefulness of telepsychology were both uniquely associated with current use of telepsychology. Receiving telepsychology training, organizational policies concerning the use of telepsychology, treatment emphases, treatment setting, and practicing within a rural area were significant predictors of current use; however, individual characteristics such as age, race/ethnicity, and years of practice were not. Organizations interested in encouraging psychologists to adopt telepsychology should create policies supporting the use of telepsychology and provide adequate training. Government and regulatory entities seeking to ensure treatment for individuals currently restricted from mental health services by time or geography should create clear and consistent laws permitting and governing the use of telepsychology.
