A comparative study on procedure and state of the art of conventional maximum power point tracking techniques for photovoltaic system

Due to the increasing world energy demand, renewable energy systems have been significantly applied in the power generation sector. Among the renewable energy options, photovoltaic system is one of the most popular resources which has been experiencing a huge attention during recent decades. The remarkable advantages, such as static and movement free characteristics, low maintenance costs, and longevity are the primary factors for the popularity of solar generation in the late years. Nevertheless, the low PV conversion efficiency in one side and high PV material cost in the other side have made PV generation comparably expensive system. Consequently, a capable maximum power point tracking (MPPT) is all important to elicit the maximum energy from the production of PV systems. Different researches have been conducted to design a fast, simple and robust MPPT technique under uniform conditions. However, due to the series and parallel connection of PV modules and according to the use of bypass diodes, in the structure of PV modules, a conventional techniques are unable to track a true MPP. Recently, several studies have been undertaken to modify these conventional methods and enable them to track the global MPP under rapidly changing environments and partial shading (PS) conditions. This report concentrates on the state of the art of these methods and their evolution to apply under PS conditions. The recent developments and modifications are analyzed through a comparison based on design complexity, cost, speed and the ability to track the MPP under rapid environmental variations and PS conditions.

Women’s reproductive choices in Australia: mapping federal and state/territory policy instruments governing choice

The reproductive choices available to women, and the consequences of those choices, exist within the broader policy context whereby policy is influenced by pervasive ideologies of women’s roles in society and the family. Women’s reproductive rights and their resulting consequences are governed by policy at the federal and state/territory levels within Australia yet little is known about the number or scope of these policies. This study aimed to systematically search and map Australian policy to identify the number and scope of policies governing women’s reproductive choices and their consequences, including how policy interprets the role of women in society through their reproductive choices. The systematic search identified 147 Australian policies in 2013. The mapping of the policies identified common themes that drive policy agenda impacting women’s reproductive choices, including those where the focus is promoting motherhood and/or children, providing economic incentives, regulating reproduction, or a broader health focus. These policy agendas simultaneously construct and are shaped by the context in which women’s reproductive choices and impacts occur. Women’s reproductive choices are highly politicised and regulated, impacting women’s position within society.

People and state in socialist Cuba : ideas and practices of revolution

This book is a political and anthropological analysis of the concept of Revolution as it is understood and experienced by Cubans in their daily lives. Urban agricultural movements, alternative medicine, self-employment, and migration reveal complex interactions and disrupt assumptions that the Cuban sate is a static, anachronistic regime.

Inspiration and mimesis in Plato's criticism of poetry

Plato criticizes poetry in several of his dialogues, beginning with Apology, his first work, and ending with Laws, his last. In these dialogues, his criticism of poetry can be divided into two streams: poetry is criticized for either being divinely inspired, or because it is mimetic or imitative of reality. However, of the dialogues which criticize poetry in these ways, it is not until Laws that Plato mentions both inspiration and mimesis together, and then it is only in a few sentences. Furthermore, nowhere in the dialogues does Plato discuss their relationship. This situation has a parallel in the secondary literature. While much work has been done on inspiration or mimesis in Plato’s criticism of poetry, very little work exists which discusses the connection between them. This study examines Plato’s treatment - in the six relevant dialogues - of these two poetic elements, inspiration and mimesis, and shows that a relationship exists between them. Both can be seen to relate to two important Socratic-Platonic concerns: the care of the soul and the welfare of the state. These concerns represent a synthesis of Socratic moral philosophy with Platonic political beliefs. In the ‘inspiration’ dialogues, Ion, Apology, Meno, Phaedrus and Laws, poetic inspiration can affect the Socratic exhortation which considers the care of the individual soul. Further, as we are told in Apology, Crito and Gorgias, it is the good man, the virtuous man - the one who cares for his soul - who also cares for the welfare of the state. Therefore, in its effect on the individual soul, poetic inspiration can also indirectly affect the state. In the ‘mimesis’ dialogues, Republic and Laws, this same exhortation, on the care of the soul, is posed, but it is has now been rendered into a more Platonic form - as either the principle of specialization - the ‘one man, one job’ creed of Republic, which advances the harmony between the three elements of the soul, or as the concord between reason and emotion in Laws. While in Republic, mimesis can damage the tripartite soul's delicate balance, in Laws, mimesis in poetry is used to promote the concord. Further, in both these dialogues, poetic mimesis can affect the welfare of the state. In Republic, Socrates notes that states arc but a product of the individuals of which they are composed Therefore, by affecting the harmony of the individual soul, mimesis can then undermine the harmony of the state, and an imperfect political system, such as a timarchy, an oligarchy, a democracy, or a tyranny, can result. However, in Laws, when it is harnessed by the philosophical lawgivers, mimesis can assist in the concord between the rulers and the ruled, thus serving the welfare of the state. Inspiration and mimesis can thus be seen to be related in their effect on the education of both the individual, in the care of the soul, and the state, in its welfare. Plato's criticism of poetry, therefore, which is centred on these two features, addresses common Platonic concerns: in education, politics, ethics, epistemology and psychology.

Changing the nature of teachers' work : an enquiry into the relationship between capital, the state and education

Examines the extent to which education has become a focus for capitalist intervention resulting in the restructuring of schools. Teachers were interviewed to identify changes in their work. The theories used to explain these changes are based on a Marxist approach. The thesis examines the ways in which the work of schools is constructed, arguing that the intellectual potential and creativity of both teachers and students is constrained by an education system that is constructed to meet the productive and reproductive needs of capital.

Construction and regulation of “dangerous consumptions” : re-regulating state casino capitalism - an Australian regulatory case study

This paper explores insights into the regulatory state and state capitalism through the lens of how states construct and regulate markets in the area of ‘dangerous consumptions’, in particular, land-based casino gambling. It focuses on what is needed for public interest regulation; with a focus on consumer protection and harm prevention. Gambling constitutes a site of explicit state regulation as the state decides and negotiates license-to-operate conditions along with the degree of significance accorded to impact/harm, regulatory monitoring and enforcement, harm prevention and state/operator duty of care...

Development NGOs, semiclientelism, and the state in the Philippines: from “crossover” to double-crossed

Civil-society participation continues to be a considerable focus of debate surrounding politics and public-policy making at international and national scales, especially in the developing world. Important examples of such processes have occurred in the Philippines. The Philippine polity is widely regarded as embodying a culture of clan-based politics entailing considerable relationships of clientelism and semiclientelism. Yet there is also considerable evidence of widespread civil-society activism. This paper examines how politically left-of-center development nongovernment organizations (NGOs) and people’s organizations (POs) have attempted to “cross over” to state positions in order to implement social and economic reforms. Select engagement by key personnel from the NGO sphere has often been premised on the notion that it was aimed at transforming these features of Philippine politics. Engagement with two recent and (claimed to be) reforming governments has not led to positive outcomes. The Philippine experience, for the most part, is an expression of the problematic assumptions that have tended to inform the debate over civil society and state interaction in many developing-country contexts. Such conceptions have been inserted into an all-encompassing notion of democratic transition, whereby political and economic liberalization are supposed to emerge in synergy, with civil society acting as a form of “stabilizer” compensating for and complementing the role of the state. Given the predominance of such weak states as the Philippines in the developing world, it is important to consider what the impacts of development NGOs participation may be. Most important, what may be the impacts of such forms of participation in a society and polity characterized by entrenched clientelist relationships? Contrasting a Gramscian analysis with Putnam-inspired conceptions of civil society that underpin the transition model, the paper argues that far from being a conditioning force on the state, civil society is itself a sphere where clientelism and semiclientelism predominate. So powerful are these forces, that arguably well-intentioned NGO personnel who previously adopted a critical stance toward neo-clientelism ultimately become absorbed by these relationships.

Microtubule dynamics in compatible and incompatible interactions of soybean hypocotyl cells with Phytophthora sojae

The arrangement of microtubules in soybean (Glycine max) cells was examined during compatible and incompatible interactions of hypocotyls of soybean cv. Harosoy (susceptible) and cv. Haro 1272 (resistant) with race 1 of the soybean-specific pathogen Phytophthora sojae. Both reaction types were similar during the first 3 h after zoospore inoculation in terms of the number of cells penetrated, and depth penetrated into the cortex. By 3 h postinoculation, clear differences had developed between the two interaction types: incompatible interactions were characterized by a hypersensitive response that was confined to single penetrated cells; while compatibly responding cells appeared unchanged. Both types of response were characterized by autofluorescence of cell walls or cytoplasm and, at 6 h after inoculation, complete disorganization of cell cytoplasm. Reorientation and loss of microtubules was seen in the early stages of the incompatible interaction in association with cellular hypersensitivity, but not in compatible responses. In cells adjacent to those that reacted hypersensitively, there was little evidence of change in microtubule orientation. Treatment of hypocotyls with the microtubule depolymerizer oryzalin prior to inoculation did not alter the compatible response, but led to breakdown of the incompatible response. Changes in microtubule orientation and state are thus among the first structural changes that are visible within cells during incompatibility in this system.

Gender blind? Australian immigration policy and practice, 1901-1930

This paper seeks to explore the nature of Australian immigration policies and practices, particularly their impact on women, from federation in 1901 to the cessation of large-scale assisted immigration to Australia brought about by the 1930s depression. The characteristics that influenced and affected female immigrants may have differentiated their experiences from those of male immigrants in the same period. Differential treatment of men and women has often been an unstated given in the formulation and implementation of immigration policies. It was as common to non-government organisations (of which there were, and still are, a great many associated with immigration and settlement), as to governments, both federal and state. Several inequities can be identified in the making and implementation of immigration and settlement policies, and in the access to government grants, concessions and services, not only in terms of race, ethnicity, class or occupation (which is well trodden ground in this field) but also in terms of gender.[1] Such differentiation is part of the broader framework of changing conceptions about the place and roles of women in Australian society and their expected contribution to the nation, but it has remained largely unexplicated in this period and field.

Pharmaceuticals in Australia: developments in regulation and governance

The pharmaceutical domain represents a type of internationalised policy network theorised in recent writings on neo-liberalism, neo-corporatism and governance. This article presents an analysis of developments in prescription drug regulation in Australia. A relatively stable, state-managed pattern of interaction has been superseded by less closed exchange, and the government itself has fragmented into agencies pursuing different objectives. Developments in the three core regulatory areas are described: safety and efficacy controls, social policy (access and equity), and state support for industry (economic) development. Consensus-building occurs within the context of the National Medicines Policy. The pharmaceutical industry, represented by Medicines Australia, has a stake in all aspects of pharmaceutical policy and regulation, and draws upon unique resources (expertise and lobbying capacity). The context for the developments described is Australia's abandonment of a protectionist version of the Keynesian welfare national state in favour of the model of the competition state, which is oriented towards support for the growth of high technology industries such as pharmaceuticals, premised on partnerships with business.

Exercise dependence and elite athletes: perceptions of coaches of elite athletes.

Exercise dependence (EXD) is a psychological condition associated with physical, emotional, social and performance consequences. Despite growing awareness of the prevalence of EXD within the athletic population, the symptoms or dimensions that comprise the condition largely remain unclear. The aim of the present study was to examine the perceptions of coaches relating to the symptoms or dimensions that define EXD among athletes. Participants were 90 coaches of elite athletes employed by the Australian Institute of Sport and State Institutes of Sport in Australia. Coaches completed an EXD checklist and a separate checklist of characteristics of committed exercisers. Both checklists contained 31 dimensions. The results supported a constellation of cognitive, emotional, behavioral, physical, social and performance dimensions. The results are discussed in terms of the consequences of EXD for elite athletes. Implications for coaches and teammates of elite athletes who experience EXD are also highlighted.

Reconstituting the invisible out of structure and repetition: a walk through diary V3.2.

This presentation will discuss the production of an interactive personal diary constructed in digital form as an interactive CD-Rom: Diary V 3.2. This diary was conceived as a digital version of the family photo album of the artist's nuclear family, which unfortunately disintegrated during 4 years of the diary's making. As a result Diary V 3.2 became more a documentation of the mood and state of mind of the maker than the family it began to focus on. It acted more as a trace or a remnant of mood, an artifact of loss. This was communicated not so much through narrative but ideas of loss and erasure. Another layer to this work concerns the migration of images, technique from the old analogue technology to the new digital technology which can act as a replay of the migrant experience.
