title: Tension between substantive and instrumental rationalities: case study of on ecovillage in the south of Bahia

description: Abstract The present article aims to investigate the manifestations of the tension between substantive and instrumental rationalities in management of the Itapeba Ecovillage. It is an ex-post-facto qualitative research. Was adopted ethnography as our methodological strategy. Was applied participant observation at the Itapeba ecovillages between May and September 2011. Was adopted the substantive approach to organizations as our theoretical basis. This work introduces in the Administration Science the study on a previously unpublished kind of organization, the ecovillages. The result of the analysis of the fieldwork point to the following conclusions: instrumental and substantive rationalities are not self excluding; the process of communication provides support to balance between self-imposed normativity of management with aspirations, values and self actualization of subjects; regular gatherings, decision making, conflict management, rituals celebrations and unplanned gatherings are all part of the interpersonal relationships universe of sustainable communities; the creation of spaces designed for decision making and exercise of political life that privilege substantive rationality do not imply the reduction of typical instrumental spaces such as technical and bureaucratic ones; to participate in decision processes, to have accesses to political and power instances and the possibility to affirm personal principles are essential to conciliate personal expectancies and organizational demands; ecovillages represent a synthesis between knowledge and action, between theory and practice, and are viable answers to the current civilization crisis.

title: PRODUCTION MANAGEMENT AND EMPLOYEES - A SURVEY OF AUTO PARTS COMPANIES

description: ABSTRACT Purpose: This paper presents an overview of the adoption of methods of production management methods for auto parts companies in Brazil and verifies if there is involvement of shop floor workers in their use, taking into consideration the relevance of involvement to organizational performance and obtaining the results expected from the adoption of these methods, as indicated by in line with research on participatory management and the manuals in the area of operations management. Originality/gap/relevance/implications: Involvement is a significant construct in product management and has been widely researched, but little research has been dedicated to investigating whether there is any involvement of employees in the use of multiple methods. Most of the existing research concentrates analysis on the adoption of a single method in isolation and in the literature it has been observed that companies do not always follow the recommendation to involve workers in their use, thus what motivated this study. Key methodological aspects: We conducted a survey in 95 auto parts companies to gain access to information about a wide range of auto parts companies, plotting an overview of the adopted production management methods adopted and examining the extent of the involvement of employees. Summary of key results: Most of methods investigated were widely adopted by the companies surveyed. Generally, the surveyed companies stated that there is employee involvement, although this varies from one method to another. The study identified cases in which methods have been adopted and after some time have ceased to be used by some companies. The abandonment of Six Sigma occurred mainly in companies in which there was no involvement of employees in the application of this method. The method most commonly abandoned, however, was the suggestion program, despite exhibiting greater employee involvement, indicating that some companies continue to experience difficulty applying this type of method over time. Limited time for training may also have hampered the use of some methods. Key considerations/conclusions: The researched methods have been implemented by the examined companies. The research confirms that quality still plays a major role concerning employee involvement; representing one of the most noticeable aspects regarding lean production. Most of the investigated training is focused on this area, but the fact that time dedicated to training is short helps elucidate the difficulty related to involvement in methods which require a higher level of formal training. Cases in which companies implemented certain methods and soon discontinued them have been observed, highlighting the suggestion program, in which the employee involvement is central; what indicates that difficulties related to this involvement remain in some companies.

title: Quantification of Treg cells in peripheral blood and lymph nodes of dogs with multicentric lymphoma

description: ABSTRACT Lymphoma is a malignant tumor characterized by cell proliferation of lymphoid origin and corresponds to 90% of all hematopoietic neoplasms of dogs. Regulatory T cells (Tregs) have been the target of many investigations in oncology due to their potential of down-regulating immune responses, as well as ensuring the maintenance of active mechanisms of tumor suppression. The aims of the present study were to compare the percentage of Tregs in peripheral blood between dogs with multicentric lymphoma and healthy animals, together with the percentage of Tregs in peripheral blood and lymph nodes of dogs with multicentric lymphoma. Twenty-six animals were enrolled in the study: 10 healthy dogs comprised the control group (CG) and 16 dogs with multicentric lymphoma comprised the Lymphoma Group (LG). We observed that dogs in the LG showed a significantly higher Tregs expression in peripheral blood compared to the CG. No significant difference was observed between Tregs expression in lymph nodes and peripheral blood of the LG, however. With these results, it is possible to conclude that multicentric lymphoma is a neoplasm with high Tregs expression, which poses this as a condition of interest when investigating treatments that can suppress Regulatory T cells.

title: Use of fluralaner on canine generalized juvenile demodicosis treatment: case report

description: ABSTRACT The aim of the present study was to report the efficiency of fluralaner on the treatment of two cases of canine generalized juvenile demodicosis. Two puppies, aging two and three months old, with the clinic and parasitological diagnosis of generalized demodicosis were treated with single administration of fluralaner. according to the dose recommended by the responsible laboratory. Additionally, adjuvant therapy was applied using benzoyl peroxide shampoo and domperidone. A satisfactory therapeutic response was observed, and complete repilation was present at the 30th day after drug administration. For each patient, at the 75th and 90th day after the treatment began, skin scrapings were performed in order to investigate the presence of Demodex sp; and all were negative. Considering the high efficiency of the treatment used, we suggest the inclusion of fluralaner on the therapeutic protocol for canine demodicosis, particularly in pediatric patients and with the generalized form of the disease.

title: Allergic dermatitis due to bite of Culicoides in muar: case report

description: ABSTRACT Allergic dermatitis to ectoparasite bites is a common parasitic disease among domestic animals, being reported mainly in small ruminants and companion animals. However, the disease is poorly diagnosed in equine clinics due to nosological similarities with other skin diseases. The aim of this case report was to describe the clinical syndrome, the diagnostic plan and the therapeutic management of a mule affected by this disease. An 8-year-old mule was observed at Universidade Federal Rural de Pernambuco, presenting papular-crusted and pruritic cutaneous lesions with clinical evolution of two years. In three previous situations, the disease had been treated as fungal dermatitis by other veterinarians. For the diagnosis, cytopathological and parasitological examination of the skin, bacteriological and fungal culture, histopathological analysis and blood count were performed. The exams showed a chronic eosinophilic perivascular superficial dermatitis. A topical therapy with dimethyl sulfoxide, sulfadiazine, urea, and vitamin A was indicated. The therapeutic protocol was satisfactory, allowing complete remission of the clinical condition. This work reported clinical and pathological findings of allergic dermatitis to the bites of Culicoides spp. in muar, in addition to alerting about the importance of complementary examinations for the accomplishment of the differential diagnosis and adequate therapeutic orientation.

title: Melatonin treatment of pre-veraison grape berries modifies phenolic components and antioxidant activity of grapes and wine

description: Abstract A comprehensive investigation was conducted to determine the effects of exogenous melatonin treatment of pre-veraison grapes on phenolic components and antioxidants of grape berries and wine. The results showed an increase in the concentration of cyanin-3-O-glucoside, peonidin derivatives, and two flavanols [namely (+)-catechins and (−)-epicatechins] of grapes, as well as flavonols in both grapes and wine due to the application of melatonin. These compounds are derivatives of the catalysate of flavonoid 3’-hydroxylase (F3’H) in the flavonoid synthesis pathway of plants. It can be inferred that melatonin increased the activity of F3’H or expression of VvF3’H during grape berry maturation. In addition, two melatonin treatments of pre-veraison grape berries reduced the DPPH radical-scavenging ability and copper ion-reducing power of grapes and wine, whereas one melatonin treatment just reduced those in wine. This study will provide a practical strategy to change the phenolic composition of grapes and wine.

title: Phytochemical analysis and fungicide potential of Pouteria ramiflora against Lasiodiplodia theobromae

description: ABSTRACT The use of plant extracts can be an alternative to reduce the use of pesticides, to control diseases and pests that affect agricultural production. The aim of this study was the chemical characterization of the extract and fractions of Pouteria ramiflora leaves and to determine its fungistatic potential on Lasiodiplodia theobromae. The ethanolic extract of dried and crushed leaves was obtained by maceration. Part of this extract was sequentially partitioned and the following fractions were obtained: hexane, dichloromethane, chloroform, ethyl acetate, n-butyl, and hydromethanol for subsequent bioassay, and qualitative and quantitative phytochemical analysis. Experimental development comprises of adding a L. theobromae mycelial disk (5 mm), obtained from pure colonies, in the middle of Petri dishes with PDA culture growth (potato-dextrose-agar) plus the aforementioned substances in different concentrations (800; 1,200; 1,600; 2,000, and 2,400 µg/mL), and a control treatment (PDA). The plates were incubated in B.O.D. (25±2°C), and the assessment was performed by measuring the diameter of the colonies until it reaches the edge of the board. The experimental design was completely randomized with five replications, and the treatments were constituted of a factorial of seven extracts/fractions and six concentrations. For the Mycelial Growth Rate Index (MGRI) obtained, the analysis of variance was performed, and when significant, the regression analysis was performed. All extract/fractions decreased MGRI of L. theobromae, as the concentrations were increased. The best MGRI reduction occurred in n-butanolic fraction, and the efficiency of this fraction may be related to the presence of flavonoids and anthraquinones. The extract and fractions of P. ramiflora, a tree from the Cerrado biome in Mato Grosso do Sul, was effective in the control of L. theobromae, which can be used as a control option in organic farming or in integrated management systems.
