A pratica regular de atividade fisica tem sido recomendada para a prevencao e reabilitacao de doencas cardiovasculares e outras doencas cronicas por diferentes associacoes de saude no mundo, como o American College of Sports Medicine, os Centers for Disease Control and Prevention, a American Heart Association, o National Institutes of Health, o US Surgeon General, a Sociedade Brasileira de Cardiologia, entre outras. Estudos epidemiologicos tem demonstrado relacao direta entre inatividade fisica e a presenca de multiplos fatores de risco como os encontrados na sindrome metabolica. Entretanto, tem sido demonstrado que a pratica regular de exercicio fisico apresenta efeitos beneficos na prevencao e tratamento da hipertensao arterial, resistencia a insulina, diabetes, dislipidemia e obesidade. Com isso, o condicionamento fisico deve ser estimulado para todos, pessoas saudaveis e com multiplos fatores de risco, desde que sejam capazes de participar de um programa de treinamento fisico. Assim como a terapeutica clinica cuida de manter a funcao dos orgaos, a atividade fisica promove adaptacoes fisiologicas favoraveis, resultando em melhora da qualidade de vida.
Globalisation and the sustainability of farmers, livestock-keepers, pastoralists and fragile habitats

In the second half of the twentieth century, industrial agriculture together with the integration and globalisation of the food chain successfully increased the quantity of food and reduced unit prices to the consumer in Western society. Many policy-makers now advocate expansion of this industrial model into the developing regions as the only feasible way to feed the 9.6 billion people expected by 2050. However, industrial agriculture is unsustainable, costly and damages the environment. Expansion of this food production model to Africa, Asia and Latin America will force migration to the cities of several billion people from small farms, including those who manage dryland habitats and other fragile ecosystems, thus exposing these rich areas of biodiversity to neglect or abuse. The alternative way to increase world food supply is to empower small-scale farmers and pastoralists, a policy endorsed in principle by governments in 2012 but lacking major implementation to date. Proposals are made for realistically redressing current economic policies for agriculture and food to empower these historic guardians of agro-bioresources so that they may increase food security and ensure the conservation of vast areas of dryland and other natural habitats.
Novel Self-Configurable Current-Mirror Techniques for Reducing Current Imbalance in Parallel Light-Emitting Diode (LED) Strings

Traditional current-mirror methods require one fixed current reference for controlling other current source or sources. In this paper, a new self-configurable current-mirror method that can dynamically determine the best current branch as the current reference in order to ensure good balance of all parallel current sources is proposed. The operating principle involves a dynamic and self-configurable transistor-based current-balancing circuit that can be operated in saturation or linear mode. In either operating mode, good current balance or sharing among all parallel-connected current sources can be guaranteed. The novel current-balancing circuit does not require a separate power supply for powering their control circuits. The proposal is a modular one that can be expanded to any number of parallel current sources. Its principle has been successfully applied to current balancing of parallel LED strings.
Change Management As An Emerging Function In Organization

The emerging changes in small and medium enterprises had created a new dimension in the management functions hitherto being performed in the field before. There is need to look into various environmental changes facing small and medium enterprises nowadays and find means of tackling these dynamic and turbulent changes as it impact the SME organizations. Are there new and emerging changes in the environment? Is there need for SME to be resilient in managing these changes? This paper is set out to investigate the various emerging changes impacting SME organizations. It shall also fashion means of tackling such changes. The theoretical approach to be employed for this study is taken from Sarah Dixon's Dynamic Competitive Life Cycle model. The researchers equally use journals, articles and on-line publications as source of research. The imperative of managers of SME to learn from dynamic life cycle model not only for competitive advantages but as sources of fashioning out business strategy was evolved in this write up.
Fluorescence In Situ Hybridization and Spectral Imaging of Coral-Associated Bacterial Communities

ABSTRACT Microbial communities play important roles in the functioning of coral reef communities. However, extensive autofluorescence of coral tissues and endosymbionts limits the application of standard fluorescence in situ hybridization (FISH) techniques for the identification of the coral-associated bacterial communities. This study overcomes these limitations by combining FISH and spectral imaging.

Is the Higher-Quality Financial Reporting Improves CSR Investment Efficiency and Future Financial Performance? – In Indian Perspective

This study searches for the role of financial reporting quality in disciplining managers’ investments in corporate social responsibility (CSR) in Indian companies. While agency have similar kind of problems which relates to investment decisions, with respect to investment in CSR, the moral exposure problem that results in over-investment is likely exacerbated as CSR provides certain concealed benefits to managers that would not be anticipated from a typical investment. I have recognized that there is a positive relation between investment in CSR and future profitability for firms with high-quality financial reporting; whereas there is a negative relation between investment in CSR and future profitability for firms with low-quality financial reporting. In general, these outcomes has recommended that higher-quality financial reporting improves CSR investment efficiency by justifying moral helplessness, resulting in an investment in CSR that benefits stake holders by improving future financial performance.
On local vascular reactions and their interpretation

IN the previous paper I have shown that there is no constriction of denervated organs during splanchnic stimulation if the suprarenals have been previously cllt out of the circulation. It may be remembered that the constriction obtained in denervated limbs during, the rise of pressure produced by splanchnic stimulation was regarded by Baylissm as an important link in the chain of evidence brought forward by him for the existence of local reactions of the blood vessels to variations of internal pressure. I determined therefore to repeat the other experiments quoted by Bayliss with a view to determining whether this power of local reaction to pressure was really present, and if not, in what other way the experimental results might be accounted for. The other methods used by Bayliss to produce a rise of internal pressure were stimulation of the central end of the sciatic nerve and asphyxia.
The experience of xenophobia in South Africa.

In May 2008, xenophobic violence erupted in South Africa. The targets were individuals who had migrated from the north in search of asylum. Emerging first in township communities around Johannesburg, the aggression spread to other provinces. Sixty-two people died, and 100,000 (20,000 in the Western Cape alone) were displaced. As the attacks escalated across the country, thousands of migrants searched for refuge in police stations and churches. Chilling stories spread about mobs armed with axes, metal bars, and clubs. The mobs stormed from shack to shack, assaulted migrants, locked them in their homes, and set the homes on fire. The public reaction was one of shock and horror. The Los Angeles Times declared, “Migrants Burned Alive in S. Africa. ” The South African president at the time, Thabo Mbeki, called for an end to “shameful and criminal attacks. ” Commentators were stunned by the signs of hatred of foreigners (xenophobia) that emerged in the young South African democracy. The tragedy of the violence in South Africa was magnified by the fact that many of the victims had fled from violence and persecution in their countries of origin. Amid genocidal violations of human rights that had recently occurred in some countries in sub- Saharan Africa, the new South Africa stood as a beacon of democracy and respect for human dignity. With this openness in mind, many immigrants to South Africa sought safety and refuge from the conflicts in their homelands. More than 43,500 refugees and 227,000 asylum seekers now live in South Africa. The majority of people accorded refugee status came from Burundi, Democratic Republic of Congo, and Somalia. South Africa also hosts thousands of other migrants who remain undocumented.

Apolipoprotein E Gene Polymorphism in Indian Patients with Alzheimer’s Disease and Vascular Dementia

The association of apolipoprotein E (ApoE) gene polymorphism with Alzheimer’s disease (AD) has been reported in several populations including one from a rural community in North India. However, the association of ApoE polymorphism with vascular dementia (VaD) is yet to be established in this population. In a case-control study involving 54 cases of dementia (29 AD and 25 VaD) and 76 age-matched healthy controls, the frequency of Ε4 allele was significantly higher among cases of AD and VaD compared with controls (p < 0.001). The Ε3Ε3 (p < 0.05) and Ε2Ε3 (p < 0.001) genotypes were found to be protective. The odds of developing AD or VaD were 4.4 and 3.7 times higher, respectively, in the presence of even a single Ε4 allele. Our results suggest that the increased risk of developing AD or VaD is similar among Asian Indians with ApoE Ε4 compared with the Caucasian population.
The relationship between ownership structure and firm performance: An empirical analysis of listed companies in Kenya

The study investigated the effects of ownership structure on performance of listed companies in Kenya using agency theory as an analytical framework. Ownership structure was operationalized in terms of ownership concentration (percentage of shares owned by the top five shareholders) and ownership identity (actual identity of shareholders). Measures of performance were return on assets, return on equity and dividend yield. Forty two (out of fifty four) listed companies were studied using both primary and secondary data. Reliability of data was tested using Cronbach’s Alpha, while tolerance and variance-inflation factor were used to test multicolinearity. Using Pearson’s product moment correlation and logistic regression, the study found that ownership concentration and government ownership have significant negative relationships with firm performance. On the other hand, foreign ownership, diffuse ownership, corporation ownership, and manager ownership were found to have significant positive relationships with firm performance. Key words: Ownership structure, ownership concentration, ownership identity, firm performance, agency theory, corporate governance.
Environmental Reporting Regulations and Reporting Practices

ABSTRACT This study explores how four different types of environmental reporting regulations affect reporting practices. Accounting Act requirements, accounting standard requirements, accounting standard recommendations, and no regulation/voluntary disclosure are associated with different levels of reporting obligations. Disclosures made by enterprises subject to regulations are compared with those of enterprises that are not. There are separate regression models for each type of regulation. The sample consists of 235 enterprises from the private and public sectors. Content analysis is used to measure environmental disclosure. Enterprises subject to regulations report significantly more types of the information content required by law than other enterprises, which is in line with the higher regulatory legitimacy risk. There is no such difference in disclosure between the two groups of enterprises for the information required and recommended by the accounting standard. This may suggest that pragmatic, cognitive, and moral legitimacy issues outweigh the regulatory legitimacy risk for these types of information, or that legitimacy risks are generally low. Enforcement of regulations will increase the regulatory risk. For information that is voluntary for all enterprises to disclose, enterprises that are not subject to any regulations report significantly more types of information than those that are. This result is not in line with predictions made from any of the four types of legitimacy. Some alternative explanations are discussed. Since regulatory regimes may include several types of means, the main contribution is the comparison of four types of regulations within the same regime, as opposed to analysing only one type of regulation at a time such as in the extant literature. The study also explores different types of legitimacy, and addresses the lack of research on environmental reporting in the public sector.
Impacts of Absorptive Capacity on Value Creation

ABSTRACT Recent development in strategy research has demonstrated the important role of network participation in firm value creation. However understanding the key role of networks in value creation is only the first step, ft is substantial to understand, also, the underlying mechanisms that impact firms capability in appropriating and creating value through its participation in networks. Therefore, based on an empirical research study among tourism small and medium enterprises, this paper aims to demonstrate that the extent to which firms can create and appropriate value, would highly influence their absorptive capabilities.
Seasonal Pattern of Vegetative Cover from NDVI Time-Series

Indonesia manages various forested land utilizations, for instance natural forest and plantations. In the past, natural forest had been exploited throughout the country, mainly in the islands of Sumatera and Borneo (Nawir & Rumboko, 2007). Greater criticisms on forest exploitation lead to a moratorium which needs to be monitored frequently. Most of forest concessions were converted into plantations (Kartodihardjo & Supriono, 2000). Popular plantations developed in the country have been rubber and oil palm. Successful management of the plantation as well as natural forest has been under careful examination. Assessment of woody vegetation could be taken using field surveys or remote sensing. Although having possibilities to capture detailed datasets, field survey is lacking in terms of implementation: lengthy data capture and least favorable to remote areas. In these situations, remotely sensed data play a crucial role.
glypican-3 controls cellular responses to Bmp4 in limb patterning and skeletal development.

Glypicans represent a family of six cell surface heparan sulfate proteoglycans in vertebrates. Although no specific in vivo functions have thus far been described for these proteoglycans, spontaneous mutations in the human and induced deletions in the mouse glypican-3 (Gpc3) gene result in severe malformations and both pre- and postnatal overgrowth, known clinically as the Simpson-Golabi-Behmel syndrome (SGBS). Mice carrying mutant alleles of Gpc3 created by either targeted gene disruption or gene trapping display a wide range of phenotypes associated with SGBS including renal cystic dysplasia, ventral wall defects, and skeletal abnormalities that are consistent with the pattern of Gpc3 expression in the mouse embryo. Previous studies in Drosophila have implicated glypicans in the signaling of decapentaplegic, a BMP homolog. Our experiments with mice show a significant relationship between vertebrate BMP signaling and glypican function; GPC3-deficient animals were mated with mice haploinsufficient for bone morphogenetic protein-4 (Bmp4) and their offspring displayed a high penetrance of postaxial polydactyly and rib malformations not observed in either parent strain. This previously unknown link between glypican-3 and BMP4 function provides evidence of a role for glypicans in vertebrate limb patterning and skeletal development and suggests a mechanism for the skeletal defects seen in SGBS.
Voltage and Frequency Grid Support Strategies Beyond Standards

In recent years, with a higher penetration of renewable distributed generators into the ac grid network, the risk of grid instabilities and vulnerabilities has increased. This paper proposes grid support strategies that can be used to alleviate the grid frequency-voltage variations, which are indicators of the imbalance between power generation and consumption within an ac network. The proposed strategies to support grid stability in the event of frequency-voltage variation go beyond recent standards and provide extended functionalities. The preconfigured set points of active power-frequency P(f) strategy features the control of the converter's power flow direction with an adjustable power gradient transition between grid-feeding and force charge as grid loading, in response to grid frequency deviation. The distributed power generators are represented by an energy storage converter, with the capacity to discharge and charge the electrical energy storage (EES) element, primarily for grid support purposes. The EES energy storage is configured for later usage when the grid requires active power support, under line frequency deviation, used under normal conditions, or during on-peak tariff high-demand daytime hours (energy shifting for TOU, ac load shave). In addition to grid support enhancement, the P(f) strategy is combined with reactive power-voltage Q(v ) control to attempt to correct frequency and voltage deviations in a collective impact of distributed generators operation for grid stabilization purposes. The P(f) - Q (v) strategy provides an automatic active/reactive power generate/receive preconfigured control, in response to frequency-voltage deviations, in order to support the grid and prevent network instabilities. The proposed control strategy for local frequency assist and voltage assist is applicable for single and three-phase grid converters interfaced with energy storage systems. Simulations and experimental results, obtained using a single-phase 6 kVA four-quadrant EES converter, are presented to validate the proposed P( f) and Q(v) grid support strategies.
Exploring the Divides Among Students, Educators, and Practitioners in the Use of Digital Media as a Pedagogical Tool

Digital technologies pervade the higher education landscape as a way to build student engagement and enhance student learning and teaching. In practice, however, the ways in which these tools are implemented in marketing education appear to be ad hoc, rather than using a systematic approach to build engagement and provide students with the skill sets needed for 21st-century employment (including meta-skills, e.g., communication skills, critical thinking, technical skills in analytics, and understanding of connected consumer behavior). The research to date has built on the educator–student dyad. This article argues that an industry practitioner perspective also adds insight into how digital technology can rationally and purposefully be integrated into the marketing classroom. Using exploratory depth interviews with undergraduate students, educators, and industry practitioners, this article seeks to explore the emerging pedagogical challenges of representing these tripartite views in marketing module development and to provide recommendations for higher education institutions as to how best to do so.

Entry Regulation in a Linear Market with Elastic Demand

This work performs a comparative welfare analysis of two types of entry regulation in a duopolistic retail market: number of licenses and minimum distance between stores. In a linear (Hotelling) market we show that a minimum distance rule is beneficial for the consumers and disadvantageous for the firms when demand is sufficiently inelastic. The distance rule that maximises social welfare is one quarter of the market under which firms will be located at the quartiles. Those locations are also optimal under regulated prices. This analysis, which is not yet considered in the literature, is motivated by a change of entry regulation in the drugstore market in the Spanish region of Navarre
