In many early intensive behavioural intervention (EIBI) programs, such as the St.Amant Autism Programs in Manitoba, the Assessment of Basic Language and Learning Skills-Revised (ABLLS-R) is used as an assessment guide, a curriculum guide, and a skills tracking system. The ABLLS-R lists a total of 544 potential training tasks. In the St.Amant Autism Programs, the Assessment of Basic Learning Abilities-Revised (ABLA-R) is also used to assess a child’s ability to learn to perform 6 tasks, called levels, which are hierarchical in difficulty. Research has demonstrated that training tasks comparable to failed ABLA-R levels are very difficult to teach using standard prompting and reinforcement procedures, and training tasks that are mismatched to a client’s highest-passed ABLA-R level result in more aberrant behaviours than matched tasks. The purpose of this study was to evaluate whether the difficulty of the training tasks taught to children enrolled in the St.Amant Autism Early Learning Program matched the learning abilities of the children. In order to do so, five questions were examined based on the ABLLS-R, the ABLA-R, and archival data from the St.Amant Autism Programs. The results reveal several potentially important findings. First, observers who were knowledgeable about the ABLA-R reliably categorized 99 of the 544 ABLLS-R tasks into individual ABLA-R levels. Second, for a random sample of those 99 ABLLS-R tasks, Autism Consultants from the St.Amant Autism Programs averaged 90.5% agreement that those tasks were taught at the categorized ABLA-R levels. Third, across a sample of 14 children, 81% of their training tasks were mismatched to each child’s highest-passed ABLA-R level. Fourth, for that sample of 14 children and across their 31 maladaptive behaviour assessments, 61% of the assessments had a score representative of maladaptive behaviours. Fifth, for that same sample of children, their rates of acquisition of new training tasks were lower for mismatched tasks than for matched tasks. These findings have important implications for potentially improving the services that children with ASD are receiving from the St.Amant Autism Programs and other EIBI programs. / February 2016

Naphthoqinones are one of groups of secondary metabolites widespread in nature. The most important higher plant families containing naphthoqinones are Bignoniaceae, Boraginaceae, Droseraceae, Ebenaceae, Juglandaceae, Nepenthaceae and Plumbaginaceae. Naphthoquinones are also products of secondary metabolism of some fungi, lichens and algae. Many investigators have interested in these compounds because of their broadrange biological activities; antibacterial, fungicidal, antiparasitic and insecticidal. In this work, we studied the effects of juglon on hydroponically grown seedlings of L.). Flax plants were exposed to solutions with various concentrations of juglon and the growth and development of pea (Pissum sativum) plants were analyzed. The results showed that juglon significantly affect the morphology and physiology of the pea (Pissum sativum) plants. Moreover, the production of ethylene was increased due to stress conditions.

This thesis deals with the exploration of the influence of various phytohormones, primarily the influence of abscisic acid on the process of maturation and the influence of auxin and gibberellin on the process of germination of two types of conifers, Abies alba and Picea abies, often used as a material in the discovery of somatic embryogenesis. Each genotype prefers specific concentration ABA. 15 uM and 45 uM is the most effective for the cell lines Abies alba; 15 uM and 30 uM ABA for Picea abies. Auxin (IBA) and gibberellin (GA3) did not support the growth of roots of Abies alba. The interaction between fungal cultures Paxillus involutus and Amanita muscaria and between the embryos during the germination was studied as well. Fungal culture Paxillus involutus had very fast speed of growth on the germination medium. Fungal culture Amanita muscaria was growing very slowly. The effect of fungi on the germination has not been observed.

Therapist burnout is of primary concern for individuals who provide ABA therapy for those with autism or related disabilities. Prolonged high levels of work-related stress increase the risk of negative interactions and emotional exhaustion among workers. Acceptance and Commitment Therapy (ACT) may alleviate this problem. ACT has been found to decrease levels of perceived work-related stress among direct care staff. The primary purpose of the study was to evaluate whether ACT would improve positive interactions among therapists for children with autism spectrum disorder. The results indicated that the percentage of positive interactions had improved an average of 23.1% and procedural fidelity improved an average of 7% across all three participants. This study extends that of previous research by supporting the efficacy of ACT in work environments. One implication of the current study is that it could benefit the psychological well-being of ABA therapists. Future studies should examine whether ACT-exercises influence the way therapists address challenging behavior as it pertains to the quality of services delivered.

O objetivo desse trabalho foi avaliar o efeito do ácido abscísico na cor das bagas e nas características físicas, químicas, bioquímicas e de armazenamento pós-colheita da uva ‘Rubi’. O experimento foi realizado em um vinhedo comercial da cv. Rubi enxertada no porta-enxerto 420-A, localizado no município de São Miguel Arcanjo, SP (23º 31’ S, 47º 35' O e altitude de 660 m), na safra 2014/15. Foi utilizado o delineamento de blocos casualizados, com 4 tratamentos e 6 repetições. Os tratamentos consistiram das concentrações do isômero (S)-cis-ácido abscísico (S-ABA), sendo: Controle (0 mg L-1); 400 mg L-1 de S-ABA no início da maturação (IM); 400 mg L-1 no IM + 200 mg L-1 aos 25 dias após a primeira aplicação (25 DAPA) e 400 mg L-1 no IM + 400 mg L-1 aos 25 DAPA. Na ocasião da colheita, na porção equatorial das bagas foram determinadas as características colorimétricas com uso de colorímetro, obtendo as seguintes variáveis: L* (luminosidade), C* (saturação), hº (matiz) e índice de cor (CIRG). Avaliou-se também a massa fresca, comprimento e largura do cacho, baga e engaço, número de bagas por cacho, teor de sólidos solúveis, acidez titulável, relação sólidos solúveis/acidez, pH, açúcares redutores, clorofilas, antocianinas, carotenoides, compostos fenólicos totais, flavonoides totais e atividade antioxidante, além da perda de massa, degrana, podridão e período de conservação da uva. A aplicação de S-ABA promoveu pouco efeito sobre as características físicas dos cachos e bagas e nenhum efeito sobre o engaço, no entanto, propiciou aumento no teor de sólidos solúveis e na relação sólidos solúveis/acidez do mosto. O S-ABA exerceu efeito sobre o acúmulo de antocianinas das bagas da uva ‘Rubi’, além de propiciar a melhoria dos atributos de cor das bagas, evidenciada pela menor luminosidade e saturação, que conferem cor mais escura às bagas, e também pela maior média de CIRG, variando de 2,9 a 3,1 para as bagas tratadas. Para a conservação da uva, verificou-se que o S-ABA proporcionou menor perda de massa dos cachos, e consequentemente elevou a podridão, evidenciada pela maior quantidade de água. / The berries’ grapes color is due to the anthocyanins and their accumulation seems to be adjusted, at least in part, by the abscisic acid, in which exogenous application of this regulator provides an increase in the concentration of anthocyanins in the grape skin. The aim of this study was to evaluate the effect of abscisic acid in the color of the berries and the physical characteristics, chemical, biochemical and postharvest storage of grape ‘Rubi’. The experiment was conducted in a commercial vineyard cv. Rubi grafted on rootstock 420-A, located in São Miguel Arcanjo, SP (23º 31’ S, 47º 35' W and the altitude of 660 m) in the 2014/15 crop. A randomized block design was used, with 4 treatments and 6 replications. The treatments consisted of isomer concentrations of (S)-cis-abscisic acid (S-ABA), as follows: Control (0 mg L-1); 400 mg L-1 S-ABA in the early maturation (EM); 400 mg L-1 to EM + 200 mg L-1 25 days after first application (25 DAFA) and 400 mg L-1 to EM + 400 mg L-1 to the 15 DAFA. At the time of harvest, in the equatorial portion of the berries were determined colorimetric characteristics with use of colorimeter, obtaining the following variables: L* (lightness), S* (saturation), hº (hue) and color index (CIRG). It was also evaluated the fresh weight, length and width of the cluster, berry and stem, number of berries per cluster, soluble solids, titratable acidity, relationship soluble solids/acidity, pH, reducing sugars, chlorophyll, anthocyanins, carotenoids, total compound phenolics, total flavonoids and antioxidant activity, besides weight loss, threshing, rot and grape storage time. The S-ABA application promoted little effect on the physical characteristics of the berries and clusters and no effect on stems, however, resulted in increased soluble solids and relationship soluble solids/acidity of the must. The S-ABA exerted effect on anthocyanins accumulation of grape berries ‘Rubi’, as well as providing improved color attributes berries as evidenced by the lower lightness and saturation, which give darker color to berries, and also by higher average CIRG, ranging from 2,9 to 3,1 for the treated berries. For grape storage, it was found that the S-ABA resulted in less loss of weight of the clusters, and consequently increased of rot, as evidenced by the greater amount of water retained in clusters.

N-Acylethanolamines (NAEs) are endogenous plant lipids hydrolyzed by fatty acid amide hydrolase (FAAH). When wildtype Arabidopsis thaliana seeds were germinated and grown in exogenous NAE 12:0 (35 µM and above), growth was severely reduced in a concentration dependent manner. Wildtype A. thaliana seeds sown on exogenous abscisic acid (ABA) exhibited similar growth reduction to that seen with NAE treatment. AtFAAH knockouts grew and developed similarly to WT, but AtFAAH overexpressor lines show markedly enhanced sensitivity to ABA. When low levels of NAE and ABA, which have very little effect on growth alone, were combined, there was a dramatic reduction in seedling growth in all three genotypes, indicating a synergistic interaction between ABA and NAE. Notably, this synergistic arrest of seedling growth was partially reversed in the ABA insensitive (abi) mutant abi3-1, indicating that a functional ABA signaling pathway is required for the full synergistic effect. This synergistic growth arrest results in an increased accumulation of NAEs, but no concomitant increase in ABA levels. The combined NAE and ABA treatment induced a dose-dependent increase in ABI3 transcript levels, which was inversely related to growth. The ABA responsive genes AtHVA22B and RD29B also had increased expression in both NAE and ABA treatment. The abi3-1 mutant showed no expression of ABI3 and AtHVA22B, but RD29B expression remained similar to wildtype seedlings, suggesting an alternate mechanism for NAE and ABA interaction. Taken together, these data suggest that NAE metabolism acts through ABI3-dependent and independent pathways in the negative regulation of seedling development.
