Can humming caregivers´ facilitate feeding during mealtime situations with persons with dementia? A qualitative study

Background. ‘Music Therapeutic Caregiving’, defined as when caregivers’ sing for or together with persons with dementia care situations, has been shown to facilitate the caring situation, and enhance positive and decrease negative expressions in persons with dementia. No studies about singing during mealtimes have been conducted, and this project was designed to elucidate this. However, since previous studies have shown that there is a risk that persons with dementia will start to sing along with the caregiver, the caregiver in this study hummed such that the person with dementia did not sing instead of eat. Aim. To describe professional caregivers’ experiences of humming during meal time while feeding persons with dementia. Method. An intervention with caregivers humming was implemented during lunch time. Focus group interviews were conducted to fetch the caregivers experiences. Qualitative content analysis was used to analyse the interviews. Results. The caregivers described that humming disseminated relaxation and joy, and awakened memories about the songs hummed which encouraged the persons with the dementia to join in the songs. They also described that humming seemed to make the persons with dementia associate with mealtime and could make them eat more. However it also revealed suspiciousness and agitation from the persons with dementia. Conclusion. Humming during mealtime revealed mainly positive as well as some negative influences. More and larger studies are needed to be able to draw general conclusions.

Humming as a mean of communicating during meal time situations : A Single Case study involving a women with severe dementia and her caregiver

Objective: ‘Music Therapeutic Caregiving’, when caregivers sing for or together with persons with dementia during morning care situations, has been shown to increase verbal and nonverbal communication between persons with dementia and their caregivers, as well as enhance positive and decrease negative emotions in persons with dementia. No studies about singing during mealtimes have been conducted, and this pilot project was designed to elucidate this. However, since previous studies have shown that there is a risk that persons with dementia will start to sing along with the caregiver, the caregiver in this study hummed such that the person with dementia did not sing instead of eat. The aim of this pilot project was threefold: to describe expressed emotions in a woman with severe dementia, and describe communication between her and her caregivers without and with the caregiver humming. The aim was also to measure food and liquid intake without and with humming. Method: The study was constructed as a Single Case ABA design in which the ordinary mealtime constituted a baseline which comprised a woman with severe dementia being fed by her caregivers in the usual way. The intervention included the same woman being fed by the same caregiver who hummed while feeding her. Data comprised video observations that were collected once per week over 5 consecutive weeks. The Verbal and Nonverbal Interaction Scale and Observed Emotion Rating Scale were used to analyze the recorded interactions. Results: A slightly positive influence of communication was shown for the woman with dementia, as well as for the caregiver. Further, the women with dementia showed a slight increase in expressions of positive emotions, and she ate more during the intervention. Conclusion: Based on this pilot study no general conclusions can be drawn. It can be concluded, however, that humming while feeding persons with dementia might slightly enhance communication, and positive expressed emotions in persons with dementia. To confirm this, more studies on group levels are needed. Because previous studies have found that caregiver singing during caring situations influences persons with dementia positively it might be desirable to test the same during mealtime.

Um modelo de comportamento aversivo térmico em Megalobulimus oblongus e a ação de fármacos nos sistemas opióide e serotoninérgico envolvidos na nocicepção

As manifestações comportamentais em Megalobulimus oblongus após a estimulação aversiva térmica (EAT) e a ação de fármacos que atuam sobre os sistemas opióide e serotoninérgico foram analisadas, empregando-se, respectivamente, testes com placa aquecida, morfina, serotonina (5-hidróxitriptamina ou 5-HT), e dos bloqueadores, o naloxone e a metisergida. Com o procedimento utilizado, foi posível diferenciar um comportamento estereotipado indicativo de resposta à nocicepção, determinar a latencia em que tais comportamentos são inicialmente manifestados, e as alterações obtidas mediante o emprego de fármacos. A morfina foi capaz de aumentar a latência demonstrando uma ação antinociceptiva neste modelo, que foi antagonizado pelo naloxone. No tocante ao sistema serotoninérgico, tanto a 5-HT quanto a metisergida aplicadas isoladamente, provocaram uma diminuição da latência que foi relacionado com um efeito nociceptivo. Porém, quando estes dois fármacos foram aplicados conjuntamente, observou-se um efeito contrário. Os resultados obtidos neste estudo farmacológico com o M. oblongus são congruentes com estudos prévios realizados em outros modeos gastrópodos, citados na literatura, e sugerem o envolvimento de um sistema opióide e serotoninérgico nas respostas reflexas nociceptivas neste animal, sendo estas manifestadas por intermédio de um comportamento motor aversivo. Além disso, ficou demonstrada a presença de receptores de ambos os sistemas, conforme a ação dos fármacos empregados.

As encruzilhadas da autogestão: imaginário e simbólico nas empresas assumidas por trabalhadores: uma análise de empreendimentos da economia solidária

Nesta pesquisa a economia solidária (ES) é o pano de fundo. O enfoque pretendido é uma aproximação pela perspectiva organizacional. O problema de pesquisa é definido pela ausência da questão organizacional, na construção teórica da ES. O objetivo do trabalho é compreender os fenômenos organizacionais gestados por trabalhadores, no âmbito da ES. A pesquisa está delimitada às empresas assumidas por trabalhadores (EAT), são empresas convencionais que entraram em processo de crise ou falência, sendo assumidas por ex-empregados. A questão de pesquisa recai sobre a maneira com que os trabalhadores reinventam a gestão dos empreendimentos assumidos, quais as transformações operadas e as mudanças realizadas nas práticas de gestão herdadas. O imaginário e o simbólico são as categorias analíticas utilizadas para acessar a realidade dessas organizações. Articuladas à aproximação pela ótica dos grupos minoritários permitem apreender a dinâmica das transformações gestadas, o sentido das novas práticas e mapear a trajetória percorrida pelo grupo de trabalhadores ao construí-las. Dois estudos de caso são utilizados para ilustrar a dinâmica dessas transformações.

Important, unimportant a critical anticipation of the assumptions of legal positivism in Alice in Wonderland

Almost a full century separates Lewis’ Alice in Wonderland (1865) and the second, lengthier and more elaborate edition of Hans Kelsen’s Pure Theory of Law (1960; first edition published in 1934). And yet, it is possible to argue that the former anticipates and critically addresses many of the philosophical assumptions that underlie and are elemental to the argument of the latter. Both texts, with the illuminating differences that arise from their disparate genre, have as one of their key themes norms and their functioning. Wonderland, as Alice soon finds out, is a world beset by rules of all kinds: from the etiquette rituals of the mad tea-party to the changing setting for the cricket game to the procedural insanity of the trial with which the novel ends. Pure Theory of Law, as Kelsen emphatically stresses, has the grundnorm as the cornerstone upon which the whole theoretical edifice rests2. This paper discusses some of the assumptions underlying Kelsen’s argument as an instance of the modern worldview which Lewis satirically scrutinizes. The first section (Sleepy and stupid) discusses Lewis critique of the idea that, to correctly apprehend an object (in the case of Kelsen’s study, law), one has to free it from its alien elements. The second section (Do bats eat cats?) discusses the notion of systemic coherence and its impact on modern ways of thinking about truth, law and society. The third section (Off with their heads!) explores the connections between readings of systems as neutral entities and the perpetuation of political power. The fourth and final section (Important, Unimportant) explains the sense in which a “critical anticipation” is both possible and useful to discuss the philosophical assumptions structuring some positivist arguments. It also discusses the reasons for choosing to focus on Kelsen’s work, rather than on that of Lewis’ contemporary, John Austin, whose The Province of Jurisprudence Determined (published in 1832) remains influential in legal debates today.

Padre Miguelinho :o intelectual, o professor, o revolucionário - vozes que se fazem ouvir

This research work worries in building the history of the natalense priest Miguel Joaquim of Almeida Castro, Miguelinho, I don't just eat one of the heroes and martyrs of the Revolution From Pernambuco of 1817, as bill the traditional history, but also the educated man, the intellectual and the admired teacher. The studied period understands the beginning of the century XIX, when priest Miguelinho comes back to Brazil, coming of Portugal, to assume teacher's occupation in the Seminar of Olinda, and it ends in the year of 1817, marked by the Revolution From Pernambuco, one of the most important movements in the fight for the liberation of Brazil of the Portuguese domain. Miguelinho, one of the leaders of the Revolution, that also reached the provinces of Paraíba and of Rio Grande do Norte, it was executed by the real troops. Like this, he tries to understand the Priest's conflicting relationship, while representative clergyman, of a Church that almost obtained a religious monopoly, and your ideals per centuries more gone back to a social and economical order of Illumines, that even certain point condemned the attitude of the own Church. The objective, then, is to understand through the path of priest's Miguelinho life, not only the intellectual, the teacher and the revolutionary, but the representation of your political and pedagogic-educational ideas in a die historical moment and the creation of the republican myth, looking for the plurality of an universe that seeks, per times, to flee of our theoretical context

Aceitabilidade da carne caprina no hábito alimentar e percepção sobre o impacto ambiental na produção de caprinos no nordeste entre estudantes universitários

The present work has an objective of investigate the acceptability of consumption of the goat meat and studies the perception of university students on the productive sector of goats in the Northeast. The habit to eat goat meat has strong regional traditions and has been suffering the demographic, cultural, economic and personal influences. Currently, a new habit in the food consumers is observed and has been configuring itself a trend that concern with the health and welfare in general, in countries mainly developed. This fact comes directly contributing for the modernization of the production models, including the ambient conscience. The methodology applied includes bibliographical research, data-collecting through questionnaires applied in the UFRN (Federal University of Rio Grande do Norte ) and analysis of the data using statistic techniques assisted for software Statistica V6. It is concluded that the rate of consumption of goat meat is low in the population studied. The frequency of consumption is higher in times of leisure or to visit relatives. The descriptive analysis of the responses of interviewees shows ignorance of the production of goat meat and its importance to the state of Rio Grande do Norte.

Diet of Eared Doves (Zenaida auriculata, Aves, Columbidae) in a sugar-cane colony in South-eastern Brazil

Agricultores no médio Vale do Paranapanema têm relatado problemas com bandos de pombas (Zenaida auriculata) que se alimentam de cotilédones de soja na época do plantio. Na região do município de Tarumã, SP, essas aves se reproduzem em uma colônia situada em um canavial, e sua dieta é composta de 70% do peso seco por 4 grãos cultivados (em ordem de importância: milho, trigo, arroz e soja). As sementes de três invasoras (Euphorbia heterophylla, Brachiaria plantaginea e Commelina benghalensis) são importantes. Essa informação sugere que as pombas se adaptaram particularmente bem à paisagem criada pelas práticas agrícolas da região, aproveitando vários alimentos oferecidos.

Atividades comportamentais e comportamento alimentar de rã touro, Lithobates catesbeianus (Shaw, 1802), de pigmentação normal e albina em cativeiro

The behavior of bullfrogs reared in captivity must be well understood to support management practices that use efficient feeding regimes. In general, bullfrogs reared in captivity have normal pigmentation, but to develop an enhanced product, some studies have investigated the introduction of albino individuals in frog farms. The present study characterized the behavior of both pigmented and albino bullfrogs reared in captivity. In an initial experiment, 48 bullfrogs (70.5 ± 25.6 g) housed in small stalls were fed once a day at random times. Frogs were filmed and the images showed that both the pigmented and albino varieties behaved similarly: food intake was more frequent at dawn followed by light periods; moving and resting in dry areas may be associated to feeding events; frogs appeared to anticipate feeding time and to rest in the water more frequently in periods other than feeding time; daylight is the recommended period for feeding both pigmented and albino frogs. In a second experiment, 72 albino bullfrogs were fed at fixed times (10 a.m. or 4 p.m.) in small stalls. An initial weight of 23.8 ± 7.6 g was considered to evaluate frog performance, and after the animals reached 60.0 ± 20.0 g, they were filmed for behavior analyses. Food intake varied as a function of feeding time, and frogs were more likely to eat during the early hours of the day and immediately after receiving fresh food. Frogs fed only in the afternoon changed their behavior. Food supplied twice a day stimulated the albino frogs to eat at different times, but did not increase growth. Although fresh food stimulated feeding behavior, food intake was more frequent at dawn. Food supplied at this time of day should therefore be further investigated. The results did not indicate a more suitable feeding time (10 a.m. or 4 p.m.) for albino bullfrogs, or any advantage in using two feedings per day. The results provide xvi important information about bullfrogs in terms of food supply regime and activity preferences throughout the day. This novel information will contribute to future studies in this area

Caracterização comportamental e avaliação da qualidade de leite em caprinos da raça saanen no semiárido nordestino

Goats are social animals which groups are organized from dominance hierarchies, established by agonistic behaviors. The quality and productivity of the goat s milk can be influenced by the dominance hierarchy. In this context, the objectives of our work were describe the social and food behavior of Saanen goats in a semi-extensive production system; characterize the social organization from the assessment of dominance hierarchies in two seasonal periods and correlate the physicochemical quality of the goats milk according hierarchical position. The experiment was conducted in the EMPARN s experimental station, located in the district of Cruzeta/RN. We utilized 17 multiparous goats of the Saanen race, with different age and weight. The observations were performed in precipitation and drought phases. The scan method recorded the trough permanence and agonistic interactions by method "all occurrences" in the pasture the alimentary behaviors of eat, ruminate on foot, ruminate lying, leisure on foot, leisure lying and walk, by the focal animal sampling method. The goats milk was submitted to analyzes of: density, protein, fat, lactose, CSS and total solids. The animals spend most of the time feeding themselves, and the activities that demand greater energy expenditure are done in the morning. The animals changed the hierarchical structure during the seasonal periods because of the withdrawal of some individuals of the group, having more aggressive behavior in the rainy season. The dominant animal the lowet production, the more CSS and the lesser fat, the goat in the middle of the hierarchy was the one that obtained the best production and quality. We conclude that the Saanen goats adapt to the environment and the conditions of the group to ensure better survival and its production is influenced by the internal dynamics of the group

Subpopulations of mononuclear leukocytes associated with inhibition of Ehrlich ascites tumor growth by treatment with Bothrops jararaca venom

Snake venoms have been used as antineoplastic substances in several experimental models. We demonstrated in previous studies that Bothrops jararaca venom (BjV) induces inhibition of Ehrlich ascites tumor ( EAT) growth accompanied by an increase of mononuclear (MN) leukocytes in all groups inoculated with EAT and/or venom. The objective of the present study was to characterize the subpopulations of MN leukocytes involved in the inhibition of EAT growth by treatment with BjV. Swiss mice were inoculated with 1.0 x 10(3) EAT cells by the intraperitoneal route and treated with 0.4 mg/kg of BjV by the same route ( Group TV). Treatment was started 24 h after tumor cell inoculation and consisted of five intraperitoneal injections performed at 72 h intervals. After 2, 8 and 14 days, groups of animals were sacrificed and the number of B, TCD4 and TCD8 lymphocytes, macrophages and natural killer cells present in the peritoneal cavity was determined by flow cytometry. The control group consisted of animals inoculated with EAT and treated with 0.1 ml of saline under the same conditions as the experimental group ( Group T). Two additional control groups consisted of animals not inoculated with EAT and treated with saline or venom. Data were analyzed statistically by the Kruskal - Wallis nonparametric test for independent samples. on the 2nd and 8th day we observed a difference between groups T and TV ( group T > group TV) for all cell types, except natural killer cells, that only differed on the 2nd day. However, on the 14th day there was no difference in MN cells among groups. These data suggest that the inhibition of EAT is related to the toxic action of BjV on tumor cells and/or to the proteolytic effect of the venom on the mediators produced by the cells for growth modulation.

Cannibalistic behavior and functional response in Chrysomya albiceps (Diptera : Calliphoridae)

Chrysomya albiceps is a facultative predator and cannibal species during the larval stage. Very little is known about cannibalism and prey size preference, especially in blowflies. The purpose of this investigation was to determine the influence of prey size and larval density on cannibalism by third-instar larvae of C. albiceps under laboratory conditions. Our results indicate that no cannibalism occurs by third-instar larvae on first- and second-instar larvae, but third-instar larvae do eat second-instar larvae. The functional response on second-instar larvae is consistent with Holling type II. The consequences of consuming second-, compared to first- or third-, instar larvae as well as the implications of cannibalism for the population dynamics of C. albiceps are discussed.
