Chemical characterization, bioactive compounds, and antioxidant capacity of jussara (Euterpe edulis) fruit from the Atlantic Forest in southern Brazil

Samples of fruit from the jussara palm plant (Euterpe edulis), collected in different regions of the state of Santa Catarina. Brazil, were analyzed for chemical composition. phenolic acids. anthocyanins, flavonoids and fatty acids profile. Results indicated that the jussara fruit has a high lipid content (18.45-44.08%), oleic acid (44.17-55.61%) and linoleic acid (18.19-25.36%) are the fatty acids found in the highest proportion, and other components were proteins (5.13-8.21%). ash (1.55-3.32%) and moisture (34.95-42.47%). Significant differences were found in the total phenolic, total monomeric anthocyanins and other flavonoids for the samples from the five cultivation regions. The fruit from region E harvested in summer, with high temperatures and medium altitudes, had the highest contents of total phenolics (2610.86 +/- 3.89 mg 100 g(-1) GAE) and monomeric anthocyanins (1080.54 +/- 2.33 mg 100g(-1) cy-3-glu). The phenolic compound included ferulic, gallic, hydroxybenzoic and p-coumaric acids, as well as catechin, epicatechin and quercetin. The results show promising perspectives for the exploitation of this tropical fruit with a chemical composition comprising considerable phenolic acids and flavonoids compounds and showing activity antioxidant.

Self-awareness and psychosocial functioning following acquired brain injury: An evaluation of a group support programme

This study investigated a group support programme designed to improve self-awareness deficits and psychosocial functioning in a group of chronic patients (N = 21) with acquired brain injury (ABI). The participants were on average 8.6 years (range: 1-36 years) post-injury and were seen at the Brain Injury Association of Queensland, Australia. The assessment of participants involved two standardised measures of intellectual self-awareness with collateral reports from relatives. The present study introduced a new measure called the Self-Regulation Skills Interview (SRSI) which assessed higher levels of self awareness and self-regulation skills. Psychosocial functioning was assessed using a standardised self-report measure. At baseline the group had a relatively high level of intellectual self-awareness regarding their deficits, a low to moderate level of self-regulation skills, and significant psychosocial impairment. The participants were involved in a 16-week group programme which involved components of cognitive rehabilitation, cognitive-behavioural therapy, and social skills training. A post-intervention assessment indicated that participants had significantly improved levels of self-regulation skills and psychosocial functioning. A 6-month follow-up assessment indicated that overall, participants had maintained the gains made during the programme. The important role of self-regulation skills is emphasised as the principle factor contributing to the maintenance of the gains observed.

Females of the weevil Zabrotes subfasciatus manipulate the size and number of eggs according to the host seed availability

In some insects, the finding of oviposition substrate triggers the uptake into oocytes of yolk proteins that are stored in the fat body during post-embryonic development. The main host of the bean weevil Zabrotes subfasciatus (Coleoptera; Chrysomelidae; Bruchinae; Amblycerini), in which larval resources are the sole source for future egg maturation, is Phaseolus vulgaris. Despite not feeding as adults, females of this species are able to lay eggs after encountering host seeds but it is not known how females react to changes in the availability of bean seeds. In the present study, the behaviour of Z. subfasciatus facing two very different environments for oviposition is investigated, as well as how this influences offspring fitness. The results obtained show that females of Z. subfasciatus react to variations in the availability of seeds belonging to the same host species by adjusting egg size and number. Females on low bean seed density lay larger and fewer eggs than those on high bean seed density, demonstrating a trade-off between these reproductive traits. Moreover, females can adjust egg size to changing levels of host availability during the first 4 days of their oviposition period. Although no difference in offspring weight is found, those from small eggs (low competition environment) result in larger adults. No response to selection on these traits after rearing beetles on the same host for 40 generations is observed. This unresponsiveness may indicate that beetle populations behave according to their reaction norm that already allows rapid adaptation to a varying amount of host-seed availability and better exploitation of the environments of this widespread stored-seed pest.

A description of adaptive and maladaptive behaviour in children and adolescents with Cri-du-chat syndrome

Background Psychological tests can be useful to record adaptive and maladaptive behaviours of children with intellectual disability. The objective of this study was to describe the adaptive and maladaptive behaviour of children and adolescents with Cri-du-chat syndrome. Methods The sample consisted of 10 children and adolescents with Cri-du-chat syndrome (mean chronological age = 11.3 years, mean mental age = 18 months). The developmental quotient was calculated through the Psychoeducational Profile - Revised. An observational protocol was used to record adaptive and maladaptive behaviours. Results The number of maladaptive behaviours observed was different among participants. However, all of them had high rates of adaptive behaviours, such as rule-following. Conclusions These results, though preliminary, justify that we continue to think about the need for psychoeducational interventions aimed at stimulating the repertoire of adaptive behaviours, in people with Cri-du-chat syndrome.

New SMS mutation leads to a striking reduction in spermine synthase protein function and a severe form of Snyder-Robinson X-linked recessive mental retardation syndrome

We report the identification of a novel mutation at a highly conserved residue within the N-terminal region of spermine synthase (SMS) in a second family with Snyder-Robinson X-linked mental retardation syndrome ( OMIM 309583). This missense mutation, p.G56S, greatly reduces SMS activity and leads to severe epilepsy and cognitive impairment. Our findings contribute to a better delineation and expansion of the clinical spectrum of Snyder-Robinson syndrome, support the important role of the N-terminus in the function of the SMS protein, and provide further evidence for the importance of SMS activity in the development of intellectual processing and other aspects of human development.

Property rights of landholders in non-captive wildlife and prospects for conservation

In order to reduce the rate of human-induced biodiversity loss of wild species, it has become increasingly important to stem this loss on private and tribal lands and to find effective policies to do this. Some writers believe that granting landholders commercial property rights in wildlife might be effective in dealing with this matter and result in the sustainable use of wildlife. This paper explores this view using economic theory. In doing so, it takes into account the total economic valuation concept. While granting of commercial property rights is found to be effective for conserving some species, it is predicted to be a complete failure as a means of conserving other species. In addition, particular attention is given to the economics of the utilisation and conservation of non-captive fugitive (or mobile) wildlife. The economic theory involved is contrasted and compared with that for the exploitation of open-access resources.

Family size, economics and child gender preference: A case study in the Nyeri district of Kenya

Kenyan women have more children, especially in rural areas, than in most developing nations. This is widely believed to be an impediment to Kenya’s economic development. Thus, factors influencing family size in the Kenyan context are important for its future. A brief review of economic theories of fertility leads to the conclusion that both economics and social/cultural factors must be considered simultaneously when examining factors that determine the number of children in a family. The need to do this is borne out in Kenya’s situation by utilising responses from a random sample of rural households in the Nyeri district of Kenya. Economic and social/cultural factors intertwine to influence family sizes in this district. After providing a summary of the main statistical results from the survey, we use multiple regression analysis to explore the influences of a woman’s age, level of education, whether she has outside employment, whether the family keeps livestock, whether she expresses a preference for more boys than girls, whether the family uses only family labour (including child labour) and the size of the farm, which is used as a proxy for family income. It was found that preference for male children has an important positive influence on family size in this district. Women were found to have greater preference for male children than their male counterparts possibly because of their fear of being disinherited if they do not produce an heir for their husbands. Preference for sons was also found in allocation of human capital resources at the household level in that the female respondents were found to have lower levels of education than their male counterparts. Various long-term policies are outlined that may help to reduce the number of offspring of women in Kenya.

Learning organizations: Empirically investigating metaphors

Learning organizations are a special form of organization where enhancing learning is a strategy to increase intellectual capital. Developing learning organizations has become an imperative for many managers, since an organization's learning methods and rate may be the only source of sustainable competitive advantage. However, learning organization theory tends to be prescriptive and rhetorical, with empirical research still relatively new. This paper contributes to the literature by reporting case-study research in progress based on four Australian organizations. In the organizations studied, use of the learning organization metaphor was coupled with an emergent metaphor: organization as `family". By employing structure mapping of metaphor within analytical induction, both established methods but not combined before, this paper shows how theory might be developed from metaphor.

Deletion of 8p: a report of a child with normal intelligence

The case is presented of a female infant with a distal deletion of 8p (8p23.1 --> pter) whose development was monitored over a 5-year period from 12 months of age. Although previous literature has suggested that 8p deletion is associated with mild to moderate intellectual disability, the child reported here has normal intelligence. Despite initial delays in gross motor and language skills, cognitive development (assessed with the Bayley Scales of Infant Development) and intellectual ability (measured on the Stanford-Binet Intelligence Scale) were within average range. It is argued that the small number of previous case reports may have created a misleading impression of intellectual development in individuals with distal deletions of 8p.

The Anatomy of an International Cartel: Cyanide 1897-1927

The development of a new product or a new process, if adopted by the market, may generate a number of economic processes including secondary innovations to promote the exploitation of the new discovery. Such technological advances may also promote new industrial ventures which may exist over many decades, enhancing economic development. The history of the adoption of the cyanide process for the extraction of gold from its ores exemplifies such developments. One outcome was the formation of an international cyanide cartel.

CPR training in households of patients with chest pain

The objectives of this study are to (1) quantify prior cardiopulmonary resuscitation (CPR) training in households of patients presenting to the Emergency Department (ED) with or without chest pain or ischaemic heart disease (IHD); (2) evaluate the willingness of household members to undertake CPR training; and (3) identify potential barriers to the learning and provision of bystander CPR. A cross-sectional study was conducted by surveying patients presenting to the ED of a metropolitan teaching hospital over a 6-month period. Two in five households of patients presenting with chest pain or IHD had prior training in CPR. This was no higher than for households of patients presenting without chest pain or IHD. Just under two in three households of patients presenting with chest pain or IHD were willing to participate in future CPR classes. Potential barriers to learning CPR included lack of information on CPR classes, perceived lack of intellectual and/or physical capability to learn CPR and concern about causing anxiety in the person at risk of cardiac arrest. Potential barriers to CPR provision included an unknown cardiac arrest victim and fear of infection. The ED provides an opportunity for increasing family and community capacity for bystander intervention through referral to appropriate training. (C) 2003 Published by Elsevier Science Ireland Ltd.

Fatores intervenientes na implementação de ações estratégicas para a promoção do selo de indicação geográfica das panelas de barro de goiabeiras

Visando a proteção da propriedade industrial advinda de uma região demarcada, surgiu a Indicação Geográfica (IG). O registro da IG é conferido aos produtos ou serviços característicos de seu local de origem, apresentando qualidades únicas em função dos recursos naturais. Além disso, a IG é responsável por distinguir estes produtos em relação aos disponíveis no mercado. Neste contexto, entidades como Sebrae, MAPA e INPI, têm promovido ações estratégicas com o objetivo de apoiar a proteção do saber fazer e consequentemente, os produtos tradicionais das regiões. Tais entidades são responsáveis por promover a sustentabilidade do processo juntos aos produtores, assim como disseminar o selo para os consumidores. Assim, iniciativas como esta precisam ser apoiadas a fim de entregar resultados significativos para o desenvolvimento das regiões e seus respectivos produtos com o selo de IG. O Plano de Apoio à Gestão da Indicação Geográfica desenvolvido pelo Sebrae/ES tem três pilares: melhoria do processo de produção, promoção do produto e a sustentabilidade do processo. A presente pesquisa, baseando-se nas teorias sobre estratégia e implementação de estratégias, analisa os fatores intervenientes que contribuem para o sucesso da implementação do Plano de Apoio à Gestão da indicação geográfica das Panelas de Barro de Goiabeiras, bairro do município de Vitória, capital do Espírito Santo. A pesquisa é um estudo de caso de natureza qualitativa, exploratória e descritiva ex-post-facto. Os dados foram coletados nos documentos (plano de ação do Sebrae/ES, Livro dos Saberes e relatórios desenvolvidos por consultores especializados) e por meio de entrevistas com seis agentes de políticas públicas e cinco paneleiras, envolvidos na elaboração e implementação do plano de ação. Para a análise dos dados, adotou-se a metodologia de análise de conteúdo com index definido a posteriori. Do Plano de Apoio à Gestão da IG das Paneleiras de Goiabeiras, foram agrupadas três ações estratégicas buscando identificar em que medida os fatores intervenientes afetaram a implementação de cada ação estudada: Ação1: fortalecimento dos aspectos culturais do produto, Ação 2: fortalecimento dos aspectos sociais do produto e Ação 3: fortalecimento dos aspectos econômicos associados à diferenciação por IG. Os resultados mostraram que na Ação 1 o fator interveniente liderança superou as expectativas na implementação das estratégias. Já os aspectos políticos, o acompanhamento de resultados e a estrutura organizacional desenvolveram as ações conforme o planejado, enquanto os fatores intervenientes cultura e clareza nas estratégias apresentaram oportunidades de melhorias. Na Ação 2 somente os fatores intervenientes recursos, cultura e clareza nas estratégias apresentaram-se de acordo com o proposto, enquanto a liderança e a estrutura organizacional mostraram-se como pontos de oportunidades de melhoria. Por fim, na Ação 3 nenhum fator interveniente foi destaque como uma oportunidade de melhoria. A estrutura organizacional e os aspectos políticos apresentaram-se de acordo, enquanto os recursos e a liderança superaram as expectativas.

O PRONAF e os seus reflexos para a agricultura familiar

O presente trabalho busca através do estudo da modernização da agricultura, com foco no período de 1965-2012, compreender o papel do Estado na formulação de políticas agrícolas que conduz o desenvolvimento do modo de produção capitalista na agricultura. Utiliza-se como fonte de pesquisa dados secundários de agências governamentais, supranacionais e autores com tradição no estudo do tema, a fim de dissertar sobre as particularidades do desenvolvimento do capitalismo na agricultura em um país de economia dependente e subdesenvolvido. Para isso, faz-se necessário compreender o controle exercido pelo capital internacional sobre os elos estratégicos da economia, a perpetuação da segregação social e a superexploração do trabalho como base da sociedade nacional. Conclui-se que o Programa Nacional de Fortalecimento da Agricultura Familiar (PRONAF), política agrícola que surge em meados da década de 1990, criado para pequenos produtores, vem promovendo feitos similares à política agrícola formulada pelo Estado no período do regime militar que ficou classificado como modernização conservadora. Nesta direção, o PRONAF apresenta como estratégia o esforço de enquadrar agricultores familiares nos paradigmas da eficiência produtiva, que acaba resultando entre aqueles aptos (competitivos) e não aptos para a sobrevivência no mercado

A intensificação do trabalho docente no processo de financeirização da educação superior : o caso da Kroton no Estado do Espírito Santo

O estudo teve por objetivo investigar, a partir de duas instituições de ensino superior pertencentes ao grupo Kroton no Espírito Santo, o impacto das mudanças trazidas para o trabalho docente decorrente do processo de inserção da educação superior na Bolsa de Valores. Essas instituições são a Faculdade Pitágoras de Guarapari e a Faculdade Pitágoras de Linhares. Até 2007, juridicamente, essas instituições eram sociedades limitadas e não pertenciam ao grupo Kroton. Eram conhecidas como Faculdades Integradas Padre Anchieta de Guarapari (Fipag) e Faculdade de Ciências Aplicadas Sagrado Coração (Unilinhares), respectivamente. Em 2008, a Kroton adquire essas duas faculdades e começa a operá-las a partir da marca Pitágoras. Portanto, esta pesquisa consiste em um estudo de caso das unidades Pitágoras localizadas no Estado do Espírito Santo. Busca compreender, fundamentada em entrevista semiestruturada com 12 professores e ex-professores, como eram a organização e as condições do trabalho docente antes de essas instituições serem adquiridas pela Kroton e o que mudou após sua aquisição. Para a realização da análise teórica, a pesquisa se apoiou em Karl Marx, François Chesnais e Dermeval Saviani. Ao final, a hipótese de que, após a aquisição da Fipag e da Unilinhares pela Kroton, houve uma intensificação da exploração do trabalho docente e uma redução da autonomia do professor no que concerne às atividades de planejamento e ensino foi confirmada: pelo excessivo acréscimo de trabalho (Termo e Aula Estruturada); pela diversidade de disciplinas a que o professor esteve sujeito a ministrar; pelo regime de tensão que balizou a organização do trabalho (aumento das demissões); pela exclusão da participação do professor na escolha do referencial teórico e metodológico. Em parte, esses aspectos são fruto da combinação do taylorismo com a governança corporativa e atuaram de forma a reduzir a participação do professor nas atividades ligadas ao planejamento e ensino, reforçando, com isso, as relações sociais de dominação inerentes ao trabalho alienado.
