Gluten, with or without it: the impact of color of "gluten-free" and "with-gluten" claims in food perception

Various trends emerge frequently concerning healthy eating and gluten-free products are one of the most relevant at the moment. The present research has the goal of understanding how information regarding this component (claims “with-gluten” and “gluten-free) on the package of food products impacts the consumer’s evaluations of healthiness, caloric content and taste. We also seek to understand how the manipulation of the color of this label (green and red) can lead to a change in said evaluations. In this experimental study conducted online (Qualtrics) voluntarily participated 370 subjects (77.6% women, Mage = 28.57, SD = 10.61) distributed randomly between six conditions of the design: 3 (gluten-free, with-gluten and control) x 2 (red and green). The task consisted on the evaluation of 12 items from two distinct food categories – biscuits and bakery goods. We verified that subjects tend to consider products with the claim “gluten-free” as healthier and less caloric than others without claim; the “with gluten” condition did not differ significantly from the control condition neither from the “gluten-free” one. The manipulation of color did not impact significantly any of the evaluations. Nor did de evaluations of taste differ significantly for any of the conditions of the independent variables. It is also relevant to mention that the self-evaluated knowledge of gluten tends to be underestimated – when compared to objective knowledge – and that a gluten-free diet is thought of as superior to a conventional diet. This investigation represents a contribution for the understanding of how consumers perceive aliments and how this type of informational instruments can bias their food choices.Várias modas emergem frequentemente no que diz respeito à alimentação saudável e os produtos livres de glúten são uma das mais relevantes atualmente. A presente investigação tem como objetivo entender o impacto da informação relativamente à presença ou ausência deste componente nas embalagens de produtos alimentares (rótulos “com glúten” e “sem glúten”) na perceção dos alimentos. Propomo-nos ainda a entender de que forma a manipulação da cor deste rótulo (verde vs. vermelho) pode influenciar tais avaliações. Neste estudo experimental conduzido online (Qualtrics) colaboraram voluntariamente 370 participantes (77.6% mulheres, MIdade = 28.57 DP = 10.61) distribuídos aleatoriamente pelas seis condições resultantes do delineamento : 3 (livre de glúten; contém glúten; control) x 2 (verde; vermelho). A tarefa consistia em avaliar um conjunto de 12 exemplares de produtos alimentares (e.g., diferentes tipos de pão e bolachas) relativamente à sua salubridade, teor calórico e sabor. Verificou-se que os participantes tendem a considerar mais saudáveis e menos calóricos os alimentos que possuem o rótulo “sem glúten” comparativamente a alimentos sem qualquer rotulagem. Porém, a condição “com glúten” não se diferenciou significativamente diferente da condição “sem glúten” ou da de controlo. Não se verificou um impacto direto da manipulação da cor na perceção dos alimentos, nem uma interação deste fator com o tipo de rótulo. As avaliações de sabor não diferiram significativamente entre as condições de nenhuma das variáveis independentes. É ainda relevante mencionar que os sujeitos tendem a subestimar o seu conhecimento relativamente ao glúten – quando comparado com o seu conhecimento objetivo – e que estes entendem uma dieta livre de glúten como sendo superior a uma dieta convencional. Esta investigação representa uma contribuição para entender como os consumidores percebem os alimentos e de que forma este tipo de instrumentos informativos podem enviesar as suas escolhas alimentares

A Compiler from Array Programs to Vectorized Homomorphic Encryption

Homomorphic encryption (HE) is a practical approach to secure computation over encrypted data. However, writing programs with efficient HE implementations remains the purview of experts. A difficult barrier for programmability is that efficiency requires operations to be vectorized in inobvious ways, forcing efficient HE programs to manipulate ciphertexts with complex data layouts and to interleave computations with data movement primitives. We present Viaduct-HE, a compiler generates efficient vectorized HE programs. Viaduct-HE can generate both the operations and complex data layouts required for efficient HE programs. The source language of Viaduct-HE is array-oriented, enabling the compiler to have a simple representation of possible vectorization schedules. With such a representation, the compiler searches the space of possible vectorization schedules and finds those with efficient data layouts. After finding a vectorization schedule, Viaduct-HE further optimizes HE programs through term rewriting. The compiler has extension points to customize the exploration of vectorization schedules, to customize the cost model for HE programs, and to add back ends for new HE libraries. Our evaluation of the prototype Viaduct-HE compiler shows that it produces efficient vectorized HE programs with sophisticated data layouts and optimizations comparable to those designed by experts

Estudo preliminar de alguns factores que influenciam as pontuações atribuídas na admissão ao libro de adultos do cavalo puro sangue lusitano

Avaliaram-se a altura ao garrote e as pontuações atribuídas em concursos de admissão ao Livro de Reprodutores da raça Lusitana a 501 animais (175 machos e 326 fêmeas). Encontraram-se correlações altamente significativas de valor positivo entre praticamente todas as variáveis em estudo. Os factores classificação de mérito ou recomendado do progenitor masculino, sexo do animal e ano de admissão ao Livro de Reprodutores tiveram influência significativa sobre as pontuações obtidas pelos animais da amostra aquando da sua admissão ao Livro de Reprodutores. Os resultados obtidos mostram que tem havido um aumento do nível de exigência dos juízes na admissão dos animais ao Livro de Reprodutores, facto a que não é alheia a obrigatoriedade da apresentação dos machos montados, sendo que o mesmo efeito é de esperar se tal critério for também introduzido na admissão das fêmeas

A Tour of Gallifrey, a Language for Geodistributed Programming

Programming efficient distributed, concurrent systems requires new abstractions that go beyond traditional sequential programming. But programmers already have trouble getting sequential code right, so simplicity is essential. The core problem is that low-latency, high-availability access to data requires replication of mutable state. Keeping replicas fully consistent is expensive, so the question is how to expose asynchronously replicated objects to programmers in a way that allows them to reason simply about their code. We propose an answer to this question in our ongoing work designing a new language, Gallifrey, which provides orthogonal replication through _restrictions_ with _merge strategies_, _contingencies_ for conflicts arising from concurrency, and _branches_, a novel concurrency control construct inspired by version control, to contain provisional behavior

Mental health literacy of Mexican-American adolescents : examining their knowledge, beliefs, and attitudes about perinatal depression

The purpose of this dissertation was to examine the mental health literacy of Mexican-American adolescents concerning perinatal depression. The final project is a qualitative descriptive study via deductive and inductive content analysis. Categories and subcategories are presented using the mental health literacy framework. Participants were recruited from urban high schools in Southwestern United States. Twenty pregnant and postpartum (perinatal) Mexican-American adolescents between the ages of 15 and 19 years participated in this study. Interpersonal conflict was the most common cause of depressive symptoms as adolescents described strained relationships with the father of the baby and family members. Emotional and instrumental support were most important to adolescents in alleviating stress and depression. Family members and their significant other were individuals that adolescents turned to for support. Family members, the internet, health providers, and mothers who had previously experienced perinatal depression were mentioned as sources of mental health information. However, those who indicated internet sources were unable to explain how information would be verified for accuracy. Although participants were able to identify symptoms of depression, many expressed difficulties in recognizing depressive symptoms. Recognition was facilitated through self-appraisals and appraisal of others. Adolescents who experienced criticism due to their pregnancy status were apprehensive about discussing depressive symptoms as many feared it would lead to more criticism and judgement. Cultural beliefs surrounding motherhood influenced perceptions about depression. Participants often ignored or minimized their symptoms as mothers were often regarded as strong, resilient figures within the family unit. In regards to perceptions about health professionals and treatment, results were somewhat mixed. Adolescents were ambivalent or unfamiliar with treatments and some believed pharmacologic treatments were not beneficial. Participants overwhelmingly expressed that empathy and warmth facilitated professional help-seeking. Health care providers were seen as knowledgeable, but it was important for adolescents to first establish rapport before disclosing their mental health concerns. Utilization of the mental health literacy framework provided a comprehensive description of Mexican-American adolescents’ perceptions about perinatal depression. Consideration of sociocultural environment, values, and beliefs are indicated during interactions with and development of interventions for perinatal Mexican-American adolescentsNursin

Relació entre el creixement i la progressió de la corba en nenes amb escoliosi idiopàtica de l'adolescent

Consultable des del TDXTítol obtingut de la portada digitalitzadaIntroducció: L'etiologia de les escoliosis idiopàtiques (EI) i els factors relacionats amb la progressió de la corba són insuficientment coneguts. Els objectius del present treball foren: 1) Estudiar la relació entre la velocitat de creixement de la talla i la velocitat de creixement de l'angle, 2) demostrar que l'estabilització del creixement de l'angle té lloc al mateix temps que l'estabilització del creixement de la talla, 3) demostrar que la relació entre la talla i l'angle es modifica pel tractament i l'evolutivitat de la corba, i 4) avaluar la utilitat del signe de Risser com a factor predictiu en les EI de l'adolescent. Pacients i mètode: Estudi retrospectiu d'una cohort de 132 noies que complien els criteris d'inclusió: EI de l'adolescent, angle de Cobb ≥10º, data de menarquia coneguda, seguiment mínim de 2 anys en controls semestrals. Les principals variables recollides foren: talla i angle per a calcular les velocitats de creixement de talla i d'angle, progressió de ≥4º/any, tipus de tractament i signe de Risser. Els increments de talla i d'angle al llarg del període d'estudi es van ajustar segons diferents models de regressió curvilínia. Es considerava que el creixement s'estabilitzava quan el pendent, calculat entre dos punts de temps consecutius, canviava de signe o s'apropava a 0. Els coeficients de correlació entre la talla i l'angle per a mesures repetides es van estimar intra i intersubjectes. Resultats: L'edat mitjana de diagnòstic i de menarquia fou de 11.6 (DE 2.47) i 12.8 (DE 1.18) anys, respectivament. El pic de velocitat de la talla tenia lloc 1 any abans de la menarquia en tota la mostra. El pic de creixement de l'angle s'observava només en les corbes progressives 1 any pre-menarquia. La funció cúbica fou la que millor ajustava els valors de la talla (R2=0.329) i el pendent canviava de signe un any post-menarquia. La funció potència fou la millor per a l'angle (R2=0.038), essent el pendent proper a 0 al voltant de la menarquia. Al comparar la talla mitjana en cada període amb la del període immediatament anterior, s'aprecien diferències estadísticament significatives fins els 2.5-3 anys post-menarquia, tot i que després del primer any les diferències foren clínicament irrellevants. Respecte als valors mitjans d'angle, les diferències foren significatives en els mesos previs a la menarquia. El signe de Risser quan es produeix el pic de màxima velocitat de creixement fou 0 en el 91.5% dels casos; en el moment de la menarquia fou de 0 en el 52.9%; un any post-menarquia fou 0 en només el 2.1% de les noies, presentant valors d'un rang de 1 a 4 en percentatges diversos. Conclusions: 1. L'evolució no lineal de l'angle va impedir utilitzar la velocitat de creixement d'aquest en l'estudi de la progressió de les EI. De tota manera, s'aprecia una relació estadísticament significativa entre els valors absoluts de talla i angle, essent més forta en el grup de nenes tractades amb observació, i no sotmeses a la inferència de l'ortesi. 2. Es demostra que el creixement tendeix a l'estabilització un any després de la menarquia per als valors de la talla i al voltant de la menarquia per als valors de l'angle. 3. Hi ha un creixement estadísticament significatiu fins als 2.5 anys post-menarquia per a les noies amb observació i en els 6 mesos abans a la menarquia per a les noies tractades amb ortesi i/o amb corbes progressives. 4. Un signe de Risser de 0 informa d'una alta probabilitat de progressió potencial de la corba, però altres estadiatges del Risser no són d'utilitat per a determinar el final del creixement de la talla i de la corba.Background: Ethiology of idiopathic scoliosis (IS) still remains inadequately known, as well as factors related to curve progression. It is commonly accepted that a relation between curve progression and growth exists, but there is a lack of prospective studies on this matter in the medical literature. Main objectives of the present study were: 1) To study the relation between height growth velocity (HGV) and angle growth velocity (AGV) in IS, 2) to demonstrate that angle growth stabilisation occurs at the same time that height growth stabilisation, 3) to demonstrate that the relation between height and angle is modified by treatment type and curve progression and 4) to assess utility of Risser sign as a progression predictor in adolescent IS. Patients and methods: Retrospective study of a cohort of 132 girls who met the inclusion criteria: Adolescent IS, Cobb angle ≥10º, menarche date known, follow-up of at least 2 years in 6 months controls. Main variables collected were height and Cobb angle to calculate HGV and AGV, progression ≥4º/year, treatment (observation or bracing) and Risser sign. Several curvilinear regression models adjusted height and angle changes over time. The slope between each consecutive time points (first derivative function) was calculated. Growth was considered stabilised when slope changed its sign or was negligible. Height and Cobb angle correlation coefficients for repeated measures were estimated within subjects. Results: Mean diagnosis and menarche age were 11.6 (SD 2.47) and 12.8 (SD 1.18) years, respectively. Peak height velocity occurred 1 year before menarche in progressive and no-progressive groups. However, angle growth peak was observed only in progressive curves, and occurred 1 year before menarche as well. Cubic was the best function for height (R2=0.329) and slope changed sign at one year post-menarche. Power function was the best for Cobb angle, but with a small adjustment (R2=0.038), slope was negligible around menarche time. When comparing mean heights values in every period with the previous ones, we observed statistically significant differences till 2.5-3 years post-menarche, although after the first year differences were clinically irrelevant. As to mean angles, differences were significant since 1 year pre-menarche to menarche. Risser at time of maximal progression risk (1 year pre-menarche) was 0 in 91.5% cases; at menarche (angle stabilisation) was 0 in 52.9%; at 1 year post-menarche (height stabilisation) was 0 in only 2.1% girls, with values ranging 1 to 4 in different percentages. Conclusions: 1. The lack of a linear evolution of angle did not afford to find a correlation between HGB and AGV. Nevertheless, it exists a statistically significant relation between height and angle absolute values that is stronger in the group of girls managed only with observation, not interfered by orthosis effect. 2. The mathematical model used demonstrates that growth tends to stabilisation at one year after menarche (for height values) and around menarche date (for angle values). 3. There is a statistically significant growth till 2.5 years after menarche in girls managed with observation and in the 6 months previous to menarche in girls managed with brace and/or progressive curves. 4. A Risser sign of 0 informs of a high probability of potential curve progression, but other Risser stages are not useful to determine the end of height and curve growth

ANÁLISIS JURÍDICO DE LA NULIDAD DE SENTENCIA EJECUTORIADA EN EL JUICIO ORDINARIO.

El presente trabajo monográfico tiene como título “Análisis Jurídico de la Nulidad de Sentencia Ejecutoriada en el Juicio Ordinario” y tiene por objetivo el realizar una análisis desde la perspectiva jurídica de este recurso procesal; entendiéndose como recurso, no solo el que resulta de interponerlo ante la no conformidad con una sentencia, sino como el derecho que tiene una persona de acudir ante los organismos de justicia, cuando en la tramitación de un proceso se ha llegado a dictar sentencia, la misma que por violaciones legales carecerían de todo valor legal. Esta figura de la nulidad de sentencia ejecutoriada data de hace varios años atrás y a pesar de las reformas a la tramitación de los procesos se ha venido conservando su esencia, es decir, que la misma tiene lugar única y exclusivamente cuando la sentencia, cuya nulidad se pretende conseguir, no se encuentra aún ejecutada, es decir, cumplida la misma en todas sus partes. Se debe considerar que la demanda de nulidad de sentencia ejecutoriada se la debe tramitar por el procedimiento ordinario, ya que de la revisión del Código Orgánico General de Procesos, no existe procedimiento en el cual se adecúe su tramitación. La metodología utilizada para este trabajo de monografía es la bibliográfica ya que la misma se encuentra apoyada en la opinión de varios tratadistas sobre el tema, así como en la legislación ecuatoriana vigente y en el análisis de un proceso obtenido en Unidad Judicial de lo Civil de Ambato, llegando a obtener como resultado que son pocos los procesos de nulidad de sentencia ejecutoriada principalmente por el hecho de que en la mayoría de casos las sentencias que se dictan en los diversos juicios son ejecutadas de manera inmediata, lo que impide el éxito de este recurso procesal
