Securing small business - the role of information technology policy

As small and medium enterprises develop their capacity to trade  electronically, they and their trading partners stand to gain considerable benefit from the resulting transaction efficiencies and business  relationships. However, this raises the question of how well small business manages its IT security and the threats that security lapses may pose to the wider trading network. It is in the interest of all members of an electronic trading network, as well as governments, to assist smaller companies to secure their business data. This paper considers the relationship between IT security management and IT policy implementation among small  businesses involved in business-to-business eCommerce. It reports the results of a survey of 240 Australian small and medium businesses  operating in a cross-industry environment. The survey found a low level of strategic integration of eCommerce along with inadequate IT security among the respondents, despite the fact that 81% were doing business online and 97% identified their business data as confidential. Businesses which implemented satisfactory levels of security technologies were more likely than others to have an information technology policy within the organisation. The paper proposes a model that outlines the development of security governance and policy implementation for small and medium businesses.

Impact of the 1980 election on ideological liberal organizations

Throughout this section, I sought to establish a nexus between interest group theory and empirical observations. This in turn, would provide the framework from which I would set forth a series of hypotheses concerning the impact of the deviating 1980 elections on ideological liberal organizations. What I found in fact, was not just a link but a near perfect correlation between theory and practice, each reinforcing the other and pointing to the same ineluctable conclusion: The upshot of the Reagan/New Right landslide of 1980 was a dramatic renaissance of American liberalism. A renaissance so pervasive that ideological liberal organizations stand to benefit tremendously in terms of sustaining membership and raising funds. Moreover, it promises to facilitate the formation of liberal lobbying coalitions and enhance their capacity to cultivate grass roots support.

Acting at the Nexus : integration of research, policy and practice

This report is the result of an exciting journey of discovery. As with all journeys, we have been to many exotic places, have met extraordinary people, and at times have been challenged to keep going ahead rather than retreating. Good journeys are also enjoyed best in good company. We would like to thank VicHealth for giving us the opportunity to embark on our voyage, but also specifically to some great VicHealth staff: John Biviano, Siân Lloyd, Barb Mouy and Ali Barr have all been travelers along the way, providing us with encouragement, directions and nourishment. We know that our Project Advisory Committee and the then Chief Executive of VicHealth, dr. Rob Moody, have followed our progress on the journey with great interest. A special word of thanks to professor David Hill, chair of our advisory committee and member of the VicHealth Board of Governance, to sit down with us and critically review our navigation procedures. But we could not have reached our destination without the great assistance of the people and agencies that gave us their time, energy, and sometimes precious resources, to engage in data collection for our case studies. Again, a particular word of appreciation, to professor Brian Head, and to Ruth Belben for her incredibly efficient assistance, in organising the ARACY workshop on 24 November, 2006 in which we were given an opportunity to triangulate our position with colleagues from research, policy and practice.

HE community fights ALTC closure

While universities stand to lose more than twice as much from cuts to capital funding, it’s the abolition of the ALTC that really has the higher education community up in arms.

Review of guidelines for children's vision screenings

The aim of children's vision screenings is to detect visual problems that are common in this age category through valid and reliable tests. Nevertheless, the cost effectiveness of paediatric vision screenings, the nature of the tests included in the screening batteries and the ideal screening age has been the cause of much debate in Australia and worldwide. Therefore, the purpose of this review is to report on the current practice of children's vision screenings in Australia and other countries, as well as to evaluate the evidence for and against the provision of such screenings. This was undertaken through a detailed investigation of peer-reviewed publications on this topic. The current review demonstrates that there is no agreed vision screening protocol for children in Australia. This appears to be a result of the lack of strong evidence supporting the benefit of such screenings. While amblyopia, strabismus and, to a lesser extent refractive error, are targeted by many screening programs during pre-school and at school entry, there is less agreement regarding the value of screening for other visual conditions, such as binocular vision disorders, ocular health problems and refractive errors that are less likely to reduce distance visual acuity. In addition, in Australia, little agreement exists in the frequency and coverage of screening programs between states and territories and the screening programs that are offered are ad hoc and poorly documented. Australian children stand to benefit from improved cohesion and communication between jurisdictions and health professionals to enable an equitable provision of validated vision screening services that have the best chance of early detection and intervention for a range of paediatric visual problems.

Sprint interval and moderate-intensity continuous training have equal benefits on aerobic capacity, insulin sensitivity, muscle capillarisation and endothelial eNOS/NAD(P)Hoxidase protein ratio in obese men

Key points: Skeletal muscle capillary density and vasoreactivity are reduced in obesity, due to reduced nitric oxide bioavailability. Sprint interval training (SIT) has been proposed as a time efficient alternative to moderate-intensity continuous training (MICT), but its effect on the skeletal muscle microvasculature has not been studied in obese individuals. We observed that SIT and MICT led to equal increases in capillarisation and endothelial eNOS content, while reducing endothelial NOX2 content in microvessels of young obese men. We conclude that SIT is equally effective at improving skeletal muscle capillarisation and endothelial enzyme balance, while being a time efficient alternative to traditional MICT. Sprint interval training (SIT) has been proposed as a time efficient alternative to moderate-intensity continuous training (MICT), leading to similar improvements in skeletal muscle capillary density and microvascular function in young healthy humans. In this study we made the first comparisons of the muscle microvascular response to SIT and MICT in an obese population. Sixteen young obese men (age 25 ± 1 years, BMI 34.8 ± 0.9 kg m-2) were randomly assigned to 4 weeks of MICT (40-60 min cycling at ∼65% V˙O2 peak , 5 times per week) or constant load SIT (4-7 constant workload intervals of 200% Wmax 3 times per week). Muscle biopsies were taken before and after training from the m. vastus lateralis to measure muscle microvascular endothelial eNOS content, eNOS serine1177 phosphorylation, NOX2 content and capillarisation using quantitative immunofluorescence microscopy. Maximal aerobic capacity (V˙O2 peak ), whole body insulin sensitivity and arterial stiffness were also assessed. SIT and MICT increased skeletal muscle microvascular eNOS content and eNOS ser1177 phosphorylation in terminal arterioles and capillaries (P < 0.05), but the latter effect was eliminated when normalised to eNOS content (P = 0.217). SIT and MICT also reduced microvascular endothelial NOX2 content (P < 0.05) and both increased capillary density and capillary-fibre perimeter exchange index (P < 0.05). In parallel, SIT and MICT increased V˙O2 peak (P < 0.05) and whole body insulin sensitivity (P < 0.05), and reduced central artery stiffness (P < 0.05). As no significant differences were observed between SIT and MICT it is concluded that SIT is a time efficient alternative to MICT to improve aerobic capacity, insulin sensitivity and muscle capillarisation and endothelial eNOS/NAD(P)Hoxidase protein ratio in young obese men.

Genetics and Indigenous communities: ethical issues

 Indigenous people stand to benefit from advances in genomic technology, but genetic research in Indigenous communities has been controversial. This article reviews the ethical issues that Indigenous people and others have raised with reference to genetic research projects and biobanks. The ethical issues that apply to Indigenous people should be seen as additional to ‘conventional’ ethical issues that apply to all people, rather than replacing them. The additional ethical concerns discussed include group harm; cultural beliefs relating to biospecimens and human origins; community engagement and collective consent; benefit; ownership; and whether biospecimens can and should be ‘repatriated.’

Beyond indifferent players: on the existence of prisoners dilemmas in games with amicable and adversarial preferences

Why don’t agents cooperate when they both stand to gain? This question ranks among the most fundamental in the social sciences. Explanations abound. Among the most compelling are various configurations of the prisoner’s dilemma (PD), or public goods problem. Payoffs in PD’s are specified in one of two ways: as primitive cardinal payoffs or as ordinal final utility. However, as final utility is objectively unobservable, only the primitive payoff games are ever observed. This paper explores mappings from primitive payoff to utility payoff games and demonstrates that though an observable game is a PD there are broad classes of utility functions for which there exists no associated utility PD. In particular we show that even small amounts of either altruism or enmity may disrupt the mapping from primitive payoff to utility PD. We then examine some implications of these results.

Marcas dermatoglíficas, Antropometria e as qualidades físicas básicas dos escolares da rede municipal da cidade de Manaus

The objective of this study of comparative descriptive character went aimed at to analyze the characteristics dermatoglyphics, anthropometrics and the basic physical qualities, in 180 selected scholars in a stratified way, distributed like this: 10 year-old boys = 32; 09 years = 32; 08 years = 32; 10 year-old girls = 28; 09 years = 28; 08 years = 28), studying the fundamental teaching of the School Good Municipal Hope, located in the area east, in the Neighborhood of the Crowned, in the city of Manaus, Amazon. For identification of the dermatoglyphics characteristics collected, was the fingerprints; for evaluation of the corporal mass, height and IMC, they were used a digital scale with an estadiometer of the mark Filizola. The tests: to sit down and to reach flexibility); Horizontal Impulse or I jump in distance stopped (force of inferior members); Flex and extension of the trunk (it Forces abdominal); Flexion and extension of the arms in suspension in the bar (Force of superior members); 30 meters (Speed) and 9 minutes (Resistance applied aerobic) was to evaluate the basic physical qualities. The results demonstrated that differences didn't exist among the goods, in most of the studied variables, and the existent differences among the ages of 8, 9 and 10 years, they demonstrate a normality tendency in the infantile development

Ensaio comparativo de cultivares de soja em época convencional em Selvíria, MS: características agronômicas e produtividade

The performance evaluation it's an important procedure for recommendation of a cultivar to an specific region, because the better adapted will present superior development and bigger level of productivity. The work aimed evaluates the behavior of soybean cultivars IAC 15-1, IAC 18, IAC 20, BRS 133, FT-2000, KI-S 602 RCH, MT/BRS-55 (Uirapuru), MT/BR-45 (Paiaguas), MT/BRS-51 (Xingu), KI-S 801, MSOY 7701, MT/BR-49 (Pioneer), Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) 65 (Itapoty), Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) 64 (Ponta Pora), Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) 61, IAC 8-2, IAC 19, Crystalline FT RCH, KI-S 702, IAC Foscarin 31, IAC-PL1 and MT/BRS-46 (Conquista), related to agronomical characteristics of plants (cycle, height, height of first beans insertion and stand) and productivity of grains, when sowed in conventional time. The experimental design was randomized blocks with four replicates, and the averages compared with Tukey Test (5%). It is viable soybean production at Selviria, MS, because practically all cultivars evaluated are adapted to the soil and climate conditions of that area. To cultivar KI-S 801, the use of smaller stand to the observed in that work it can avoid lodging. Caution should be had to use cultivar MT/BRS-55 (Uirapuru).

Família e creche: crenças a respeito de temperamento e desempenho de bebês

Este estudo baseia-se na Abordagem Bioecológica de Bronfenbrenner. O objetivo foi verificar o julgamento de mães e educadoras de berçário sobre os fatores que causam ou influenciam o temperamento e o desempenho de bebês. Foram entrevistadas 50 mães que tinham filho de 4 a 24 meses em uma creche vinculada a um HC e 21 de suas educadoras (responsáveis por 90 bebês, nas fixas etárias mencionadas). As questões feitas às mães incluíam falar da rotina diária do filho, quais as competências dele e como interpretavam seu temperamento e desempenho. Para as educadoras, os temas foram os mesmos, pedindo-se para descreverem como viam cada um dos bebês sob sua responsabilidade. Os resultados mostram pouca diferença nas crenças das mães e das educadoras, sendo que a maioria apresenta crenças ambientalistas, tanto no que diz respeito ao temperamento quanto ao desempenho do bebê; e as pessoas que mais exerceriam influência seriam os pais.

Millet seeds mixed with phosphate fertilizers

O tamanho reduzido das sementes de milheto dificulta sua semeadura uniforme, principalmente para os produtores que não possuem semeadoras apropriadas. Assim, a mistura das sementes com os fertilizantes fosfatados vem sendo utilizada para facilitar a semeadura. Entretanto, o período de contato pode provocar prejuízos na germinação e no vigor. Avaliou-se a qualidade fisiológica das sementes de milheto submetidas a diferentes períodos de contato (0, 6, 12, 24, 48, 72, 96 e 120h) com os fertilizantes superfosfato simples (SFS) e superfosfato triplo (SFT), em um experimento em delineamento inteiramente casualizado em esquema fatorial 8x2 (n=4). Os atributos químicos e físicos dos fertilizantes foram previamente determinados. Foi utilizada a proporção de 1 kg de sementes para 2,5 kg de fertilizante. Após manutenção da mistura em saco plástico no laboratório, as sementes foram separadas dos fertilizantes e submetidas à determinação de umidade, germinação, primeira contagem e condutividade elétrica. Paralelamente, na casa de vegetação, em caixas plásticas contendo terra, determinou-se a emergência e o índice de velocidade de emergência, sem e com a manutenção dos fertilizantes. Porque apresentam resíduos ácidos, tanto SFS como SFT afetaram de maneira semelhante e negativamente a germinação e o vigor das sementes de milheto em mistura, na medida em que se aumentou o período de contato.

Irregular satellites of Jupiter: Three-dimensional study of binary-asteroid captures

Among the hidden pieces of the giant puzzle, which is our Solar system, the origins of irregularsatellites of the giant planets stand to be explained, while the origins of regular satellites arewell explained by the in situ formation model through matter accretion. Once they are notlocally formed, the most acceptable theory predicts that they had been formed elsewhere andbecame captured later, most likely during the last stage of planet formation. However, underthe restricted three-body problem theory, captures are temporary and there is still no assistedcapture mechanism which is well established. In a previous work, we showed that the capturemechanism of a binary asteroid under the co-planar four-body scenario yielded permanentcaptured objects with an orbital shape which is very similar to those of the actual progradeirregular Jovian satellites. By extending our previous study to a 3D case, here we demonstratethat the capture mechanism of a binary asteroid can produce permanent captures of objects byitself which have very similar orbits to irregular Jovian satellites. Some of the captured objectswithout aid of gas drag or other mechanisms present a triplet: semi-major axis, eccentricityand inclination, which is comparable to the already known irregular Jovian objects. © 2013 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.
