Adaptability, Entrepreneurship and Stakeholder Integration: Scenarios and Strategies for Environment and Vulnerability  [PDF]
Jerónimo De-Burgos-Jiménez, Diego A. Vazquez-Brust, José A. Plaza-úbeda
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.210160
Abstract: The “vicious circle” between poverty and environmental deterioration is a major challenge for those developmental approaches which look to improve the welfare of vulnerable communities. Environmental deterioration increases poverty while, at the same time, poverty causes further environmental deterioration as the business activities which communities depend upon for survival aggravate environmental deterioration by causing pollution and waste. It is therefore necessary that firms and communities collaborate in order to develop innovative solutions to break this vicious circle. This paper argues that such collaboration should be based on genuine stakeholders’ integration and entrepreneurship, proposes a holistic framework to guide business intervention strategies, and further explores collaboration scenarios between firms and communities.

Comparative Analysis of the of Management Practices and Behaviour of Small and Medium Information Technology Enterprises  [PDF]
Taciana de Barros Jernimo, Denise Dumke de Medeiros
iBusiness (IB) , 2012, DOI: 10.4236/ib.2012.44038
Abstract: This paper examines the role and influence of management practices and behaviour in successful small and medium sized information technology enterprises (SMET), based on the comprehensive concept of Mintzberg 5Ps of strategy (1992) [1]. The study employed a survey of 13 SMET with were examined on how closely they used best strategic practices in their management and how it is related to SMET performance. The discussion and conclusions highlight different ways of strategic thinking, the importance of the mutual trust and commitment between managers and employees. Specifically, we determine three elements whose greater exploration can lead to a deeper understanding of how the strategic planning is influenced by the manager’s view, in order to encourage their competitiveness through market environmental uncertainties.

Abstract: the aim of this research is to analyse the influency of some factors usually related to academic failure in college disciplines that present high failure scores. the analysis considers institutional factors, social factors and individual factors. the participants are 438 students, enrolled in disciplines of fes zaragoza which present the higher failure scores. the students were assessed by a test about factors related to academic failure at college levei and an intemational inventory of study skills. by analysing specific indicators - those related to emotional factors and to instructional methodology - results show significant differences between failed and succeed students.
A natureza e a cultura no compasso de um naturalista do século XIX: Wallace e a Amaz?nia
Alves, José Jernimo de Alencar;
História, Ciências, Saúde-Manguinhos , 2011, DOI: 10.1590/S0104-59702011000300010
Abstract: alfred russel wallace traveled through the amazon from 1848 to 1852. his perceptions of the region were informed by his systematized knowledge but also influenced by judgments of an ethical and aesthetic nature, as was common among naturalists. he saw the region's 'natives' as peaceful and friendly but likewise susceptible to the vices of civilization. nature afforded a privileged setting both for the activities of natural history and for aesthetic pleasures. these features helped keep the naturalist in the region, where he could thus engage in his scientific activities.
Prediction of the Coefficient of Thermal Expansion of Naphtha for ASTM Distillation Curve [Predi o do Coeficiente de Dilata o Térmica de Naftas pela Curva de Destila o ASTM]
Carlos Enrique de M. Jernimo
Revista Virtual de Química , 2012,
Abstract: This paper describes a calculation mechanism obtained from experimental data of ASTM and d20/4 curves to determine the volumetric expansion of naphtha. The study included historical data (experimental) of naphtha from directly distillation samples produced in a Brazilian refinery for a period of one year processing, considering the different loads used for this production. The data selection and calculations were performed at idealized routine in Excel , with values of process streams. The results were within the ranges indicated by the literature in terms of magnitude, but with deviations of less than 15% of the values listed for consideration in the projects. The adoption of this calculation mechanism is quite simple (as it considers data already available in the refineries’ control systems) and adds a good adjustment for the parameters prediction to be used in design and sizing of safety valves (PSV - Pressure Safety and Relief Valve).
School Backyard Drawings by Kindergarten Students: An Interdisciplinary Experience in the South of Brazil  [PDF]

Abstract: The recent urbanization and increasing distance between children and nature have had negative impact both in learning and in the maintenance of healthy life in the natural environment. The development and application of transdisciplinary teaching practices in sciences and visual arts afford to materialize highly relevant strategies in environmental education. Based on these principles, the present study analyzed the possible contributions of transdisciplinary efforts to children’s drawings of the environment they live in. Fifteen elementary school children were requested to draw 1) what they remembered of the school backyard; 2) what they remembered of the “nature” in the school backyard; and 3) what they saw during a visit to the backyard. In addition, semi-structured interviews were carried out to collect the children’s impressions of their drawings. The results indicate that, in addition to the grass growing in the area, playground features and other toys were consistently represented in drawings, indicating that the backyard is strongly correlated with students’ leisure and game activities. When prompted to draw nature elements, trees and some arthropods were drawn, such as insect larvae and bees. For such reasons, it is necessary to improve the students’ ties with the natural environment looking for more significant educational practices in relation to the nature in the surroundings where they inhabit.

Abstract: strawberry is a very important crop in europe and usa due to its nutritional and sensorial characteristics and its profitability. nowadays, the traditional soil based crop production is being replaced by soilless growing systems, leading to higher yield and quality all over the year. open systems with different kind of substrates in plastic bags or pots are mainly used, at plant densities from 8 to 12plants m-2. fruit yield is in the range from 5 to 10kg m-2. in general, plants are grown at 0.8-1m height above the soil surface, to isolate them from the soil and to facilitate the crop management. there are variations in the composition of the nutrient solution, reflecting differences in the conditions of crop production. plug plants are produced in containers with substrate. they are obtained from runner tips of in vitro propagated mother plants. in brazil, the strawberry soilless culture is in its first steps. production and economical results are rather unsatisfactory, and researches about more appropriated cropping systems for local conditions are needed. therefore, it is necessary to search for sustainable soilless growing systems, mainly of the closed type, to maximize yield under high water and nutrient use efficiency. plant propagation, facilities and nutrient solutions used in different countries are described. finally, guidelines for soilless crop systems appropriated for this crop in brazilian conditions are presented.
Cenozoic stress field in the southwestern Antarctic Peninsula from brittle mesostructures in Wright Peninsula, Adelaide Island
Adolfo Maestro, , Jerónimo López-Martínez
Polish Polar Research , 2011, DOI: 10.2478/v10183-011-0006-8
Abstract: Palaeostresses inferred from brittle mesostructures in the southern Wright Peninsula show a stress field characterized by compressional, strike-slip and extensional regime stress states. The compressional stress (σ1) shows a main NW-SE direction and the extensional stress (σ3) shows a relative scattering with two main modes: NE-SW to E-W and NW-SE. The maximum horizontal stress (σy) has a bimodal distribution with NW-SE and NE-SW direction. The compressional orientation is related to subduction of the former Phoenix Plate under the Antarctic Plate from the Early Jurassic to the Early Miocene. Extensional structures within a broad-scale compressional stress field can be related to both the decrease in relative stress magnitudes from active margins to intraplate regions and stretching processes occurring in eastern Adelaide Island, which develop a fore-arc or intra-arc basin from the Early Miocene. Stress states with NW-SE-trending σ1 are compatible with the dominant pattern established for the western Antarctic Peninsula. NW-SE orientations of σ3 suggest the occurrence of tectonic forces coming from fore-arc extension along the western Antarctic Peninsula.
Daphnia exilis Herrick, 1895 (Crustacea: Cladocera): Una especie zooplanctónica potencialmente utilizable como organismo de prueba en bioensayos de toxicidad aguda en ambientes tropicales y subtropicales

Abstract: the assessment of the toxic effects of chemical pollutants on the aquatic biota is fundamental for the accomplishment of control measures aimed to prevent and limit the pollution of aquatic ecosystems. zooplankters are frequently used as test organism in the aquatic toxicity evaluation, and the cladoceran daphnia magna is the main species globally used for this purpose, yet the convenience of use d. magna in tropical and subtropical regions has being discussed. nevertheless, the proposal of other surrogate species is restricted due to the lack of biological and toxicological information which justify and give support to these alternatives. daphnia exilis is a big cladoceran widely distributed in north america; in this study, a method for the controlled production of d. exilis neonates was tested. the sensitivity of this cladoceran was assessed with the reference toxicant hexavalent chromium (cr(vi)), at 20 and 25 °c. the 48-h median lethal concentration (lc50) was 0.1170 ± 0.0068 and 0.0802 ± 0.0057mg l-1, respectively at 20 y 25 °c; these values were lower than those reported for d. magna (0.2076 ± 0.0164 and 0.1544 ± 0.0175 mg l-1, at 20 y 25 °c respectively), thus indicating a higher sensitivity of d. exilis. considering its large size (both for adults and neonates), the easy culture and management, and its high sensitivity, we suggest d. exilis as a test organism adequate for toxicological studies in tropical and subtropical regions.
