Eco-efficiency considering the issue of heterogeneity among power plants

One of the main objectives in restructuring power industry is enhancing the efficiency of power facilities. However, power generation industry, which plays a key role in the power industry, has a noticeable share in emission amongst all other emission-generating sectors. In this study, we have developed some new Data Envelopment Analysis models to find efficient power plants based on less fuel consumption, combusting less polluting fuel types, and incorporating emission factors in order to measure the ecological efficiency trend. We then applied these models to measuring eco-efficiency during an eight-year period of power industry restructuring in Iran. Results reveal that there has been a significant improvement in eco-efficiency, cost efficiency and allocative efficiency of the power plants during the restructuring period. It is also shown that despite the hydro power plants look eco-efficient; the combined cycle ones have been more allocative efficient than the other power generation technologies used in Iran.

The issue of macroeconomic closure revisited and extended

Léon Walras (1874) already had realized that his neo-classical general equilibrium model could not accommodate autonomous investment. Sen analysed the same issue in a simple, one-sector macroeconomic model of a closed economy. He showed that fixing investment in the model, built strictly on neo-classical assumptions, would make the system overdetermined, thus, one should loosen some neo-classical condition of competitive equilibrium. He analysed three not neo-classical “closure options”, which could make the model well determined in the case of fixed investment. Others later extended his list and it showed that the closure dilemma arises in the more complex computable general equilibrium (CGE) models as well, as does the choice of adjustment mechanism assumed to bring about equilibrium at the macro level. By means of numerical models, it was also illustrated that the adopted closure rule can significantly affect the results of policy simulations based on a CGE model. Despite these warnings, the issue of macro closure is often neglected in policy simulations. It is, therefore, worth revisiting the issue and demonstrating by further examples its importance, as well as pointing out that the closure problem in the CGE models extends well beyond the problem of how to incorporate autonomous investment into a CGE model. Several closure rules are discussed in this paper and their diverse outcomes are illustrated by numerical models calibrated on statistical data. First, the analyses is done in a one-sector model, similar to Sen’s, but extended into a model of an open economy. Next, the same analyses are repeated using a fully-fledged multisectoral CGE model, calibrated on the same statistical data. Comparing the results obtained by the two models it is shown that although, using the same closure option, they generate quite similar results in terms of the direction and – to a somewhat lesser extent – of the magnitude of change in the main macro variables, the predictions of the multi-sectoral CGE model are clearly more realistic and balanced.

Liberating the Issue of Present Days. About the Foucaltian Critics of Inflationary Speeches on the Present as “Mass Society” and “Estatalized Space”

With this article we pretend to contribute, in a really modest way, to the liberation of a tenacious image of our society: which operates as an ideological basis of a group of current socio-political pseudocritics, with great success and diffusion. For this we will undertake the exposition and the analysis of the development group of Naissance de la biopolitique in which Foucault accomplishes the critic of all that number of inflationary speeches that represent our society like a “mass society” and a “estatalized space”. Facing these vague and disproportionate forms of consideration, the foucaltian critic, in its exquisite attention to what happens nowadays, it should reveal how our societies function as systems that optimize the difference –radically nominalists-, in which it is produced, beyond any phantasmatic of the oppressor and invasive estate, a regretion of the legal-estate structures that articulate the socio-politic groups, in benefit of the reconstitution and the social tissue as a communitarian network, suitable for the dynamics of market competence that characterise our enterprise societies. That will open to a new idea of the critic, and to a displacement of its object and objectives.

Investigating the issue of pollution in the micro-scale design of mega-cities : a case study of Enghelab Street, Tehran

Today there is a growing concern about urbanization and its impact on environmental pollution, which threatens human health and quality of life especially in mega cities. The mega city of Tehran, the capital of Iran, deals with various types of pollution. Although a large body of research has highlighted the significance of study on urban pollution in mega cities, only a few studies have addressed the issue at the micro scale. However, most of the research is restricted to air and noise pollution, whereas visual pollution as an important type of pollution that can be interpreted more deeply on a micro-scale, has been neglected. This study aims to evaluate some of the major issues of environmental pollution in Tehran by focusing on the micro-scale of the street. Therefore, as the central part of Tehran is one of the most affected divisions in the city, Enghelab Street has been selected as the case study for this research. This paper argues that identification and implementation of pollution mitigating strategies in Tehran’s master plan is not responsive enough to the whole city. This study of Enghelab Street reveals that policy making strategies for decreasing pollution should be initiated from micro-scale with further emphasis on psychological health. In the future, the lessons learned from the case study of Enghelab will help other major cities in developing countries to combat pollution through initiating from most affected districts in small scale.

The issue of data protection and data security in the (pre-Lisbon) EU third pillar

The key functional operability in the pre-Lisbon PJCCM pillar of the EU is the exchange of intelligence and information amongst the law enforcement bodies of the EU. The twin issues of data protection and data security within what was the EU’s third pillar legal framework therefore come to the fore. With the Lisbon Treaty reform of the EU, and the increased role of the Commission in PJCCM policy areas, and the integration of the PJCCM provisions with what have traditionally been the pillar I activities of Frontex, the opportunity for streamlining the data protection and data security provisions of the law enforcement bodies of the post-Lisbon EU arises. This is recognised by the Commission in their drafting of an amending regulation for Frontex , when they say that they would prefer “to return to the question of personal data in the context of the overall strategy for information exchange to be presented later this year and also taking into account the reflection to be carried out on how to further develop cooperation between agencies in the justice and home affairs field as requested by the Stockholm programme.” The focus of the literature published on this topic, has for the most part, been on the data protection provisions in Pillar I, EC. While the focus of research has recently sifted to the previously Pillar III PJCCM provisions on data protection, a more focused analysis of the interlocking issues of data protection and data security needs to be made in the context of the law enforcement bodies, particularly with regard to those which were based in the pre-Lisbon third pillar. This paper will make a contribution to that debate, arguing that a review of both the data protection and security provision post-Lisbon is required, not only in order to reinforce individual rights, but also inter-agency operability in combating cross-border EU crime. The EC’s provisions on data protection, as enshrined by Directive 95/46/EC, do not apply to the legal frameworks covering developments within the third pillar of the EU. Even Council Framework Decision 2008/977/JHA, which is supposed to cover data protection provisions within PJCCM expressly states that its provisions do not apply to “Europol, Eurojust, the Schengen Information System (SIS)” or to the Customs Information System (CIS). In addition, the post Treaty of Prüm provisions covering the sharing of DNA profiles, dactyloscopic data and vehicle registration data pursuant to Council Decision 2008/615/JHA, are not to be covered by the provisions of the 2008 Framework Decision. As stated by Hijmans and Scirocco, the regime is “best defined as a patchwork of data protection regimes”, with “no legal framework which is stable and unequivocal, like Directive 95/46/EC in the First pillar”. Data security issues are also key to the sharing of data in organised crime or counterterrorism situations. This article will critically analyse the current legal framework for data protection and security within the third pillar of the EU.

The ethics of surrogate decision making in medicine : autonomy, paternalism, or a different approach?

Knowing who to involve in treatment decisions when a patient is incapacitated has been the subject of discussion in bioethical, health law and clinical research. The major issues tend to revolve around the tension between exercising a degree of medical paternalism and respecting patient autonomy. Patients are encouraged to exert their autonomy even when they may not be capable of doing so, by means of surrogate consent or advanced directives. While liberal concepts of autonomy are exemplified in western bioethics and legal systems, clinically these decisions remain difficult, and input from medical professionals is sought, raising the issue of paternalism. A framework of bioethics, which places the patient in a relational context rather than a strictly autonomous one, may be a more helpful way of deliberating these difficult decisions

Advance Directives Refusing Treatment as an Expression of Autonomy: Do the Courts Practise What They Preach?

The principle of autonomy is at the heart of the right of a competent individual to make an advance directive that refuses life-sustaining medical treatment, and to have that directive complied with by medical professionals. That right is protected by both the common law and, to an extent, by legislation that has been enacted in the United Kingdom and many jurisdictions in Australia. The courts have a critical role in protecting that autonomy, both in those jurisdictions in which the common law continues to operate, and in those jurisdictions which are now governed by statute, and in which judicial determinations will need to be made about legislative provisions. The problem explored in this article is that while the judiciary espouses the importance of autonomy in its judgments, that rhetoric is frequently not reflected in the decisions that are reached. In the United Kingdom and Australia, there is a relatively small number of decisions that consider the validity and applicability of advance directives that refuse life-sustaining medical treatment. This article critically evaluates all of the publicly available decisions and concludes that there is cause for concern. In some cases, there has been an unprincipled evolution of common law principles, while in others there has been inappropriate adjudication through operational irregularities or failure to apply correct legal principles. Further, some decisions appear to be based on a strained interpretation of the facts of the case. The apparent reluctance of some members of the judiciary to give effect to advance directives that refuse treatment is also evidenced by the language used in the judgments. While the focus of this article is on common law decisions, reference will also be made to legislation and the extent to which it has addressed some of the problems identified in this article.

Advance directives, autonomy and the refusal of life-sustaining medical treatment

As Australian society 1s agemg, individuals are increasingly concerned about managing their future, including making decisions about the medical treatment they may wish to receive or refuse if they lose decision-making capacity. To date, there has been relatively little research into the extent to which legal regulation allows competent adults to make advance refusals of life-sustaining medical treatment that will bind health professionals and others when a decision needs to be made at a future time. This thesis aims to fill this gap in the research by presenting the results of research into the legal regulation of advance directives that refuse life-sustaining medical treatment. In the five papers that comprise this thesis, the law that governs this area is examined, and the ethical principle of autonomy is used to critically evaluate that law. The principal finding of this research is that the current scheme of regulation is ineffective to adequately promote the right of a competent adult to make binding advance directives about refusal of medical treatment. The research concludes that legislation should be enacted to enable individuals to complete an advance directive, only imposing restrictions to the extent that this is necessary to promote individual autonomy. The thesis first examines the principle of autonomy upon which the common law (and some statutory law) is expressed to be based, to determine whether that principle is an appropriate one to underpin regulation. 1 The finding of the research is that autonomy can be justified as an organising principle on a number of grounds: it is consistent with the values of a liberal democracy; over recent decades, it is a principle that has been even more prominent within the discipline of medical ethics; and it is the principle which underpins the legal regulation of a related topic, namely the contemporaneous refusal of medical treatment. Next, the thesis reviews the common law to determine whether it effectively achieves the goal of promoting autonomy by allowing a competent adult to make an advance directive refusing treatment that will operate if he or she later loses decision-making capacity. 2 This research finds that conunon law doctrine, as espoused by the judiciary, prioritises individual choice by recognising valid advance directives that refuse treatment as binding. However, the research also concludes that the common law, as applied by the judiciary in some cases, may not be effective to promote individual autonomy, as there have been a number of circumstances where advance directives that refuse treatment have not been followed. The thesis then examines the statutory regimes in Australia that regulate advance directives, with a focus on the regulation of advance refusals of life-sustaining medical treatment.3 This review commences with an examination ofparliamentary debates to establish why legislation was thought to be necessary. It then provides a detailed review of all of the statutory regimes, the extent to which the legislation regulates the form of advance directives, and the circumstances in which they can be completed, will operate and can be ignored by medical professionals. The research finds that legislation was enacted mainly to clarify the common law and bring a level of certainty to the field. Legislative regimes were thought to provide medical professionals with the assurance that compliance with an advance directive that refuses life-sustaining medical treatment will not expose them to legal sanction. However, the research also finds that the legislation places so many restrictions on when an advance directive refusing treatment can be made, or will operate, that they have not been successful in promoting individual autonomy.

Academics’ work and the concept of “profession” : an Australian case study

Universities in Australia and elsewhere have changed considerably in recent years. Inevitably, this has meant that the work of academics has also changed. Academics’ work is of importance because they are key players in universities and universities matter to the nation economically and intellectually in advancing knowledge and its practical application. Through the changes and challenges that have characterised academia in recent years, there is an assumption that academics’ work is representative of a profession. This research study investigates how academics construct their own perspectives regarding the academic "profession". The study is theoretically informed by Freidson’s theory that conceptualises professions as occupations if they are in control of their work rather than it being under the control of either the market or of their employing institutions. Two research questions guide this study. The first question investigates how academics might construct their work in ideal terms and the second one investigates the extent to which such constructions might constitute a "profession". A qualitative case study was conducted within two Australian universities. In all, twenty academics from ten disciplines took part in the study that consisted of a focus group and fifteen individual interviews. The study was conducted in three phases during which a conceptual framework of academics’ work was developed across three versions. This framework acted both a prompt to discussion and as a potential expression of academics’ work. The first version of the framework was developed from the literature during the first phase of the study. This early framework was used during the second phase of the study when five academics took part in a focus group. After the focus group, the second version of the framework was developed and used with fifteen academics in individual interviews during phase three of the study. The third version of the framework was the outcome of a synthesis of the themes that were identified in the data. The discussion data from the focus group and the individual interviews were analysed through a content analysis approach that identified four major themes. The first theme was that academics reported that their work would ideally be located within universities committed to using their expert knowledge to serve the world. The second theme was that academics reported that they wanted sufficient thinking time and reasonable workloads to undertake the intellectual work that they regard as their core responsibility, particularly in relation to undertaking research. They argued against heavy routine administrative workloads and sought a continuation of current flexible working arrangements. The third theme was that teaching qualifications should not be mandated but that there should be a continuation of the present practice of universities offering academics the opportunity to undertake formal teaching qualifications if they wish to. Finally, academics reported that they wanted values that have traditionally mattered to academia to continue to be respected and practised: autonomy, collegiality and collaborative relationships, altruism and service, and intellectual integrity. These themes are sympathetic to Freidson’s theory of professions in all but one matter: the non-mandatory nature of formal qualifications which he regards as absolutely essential for the performance of the complex intellectual work that characterises occupations that are professions. The study places the issue of academic professionalism on the policy agenda for universities wishing to identify academics’ work as a profession. The study contributes a theory-based and data-informed conceptual framework for academics’ work that can be considered in negotiating the nature and extent of their work. The framework provides a means of analysing what "academic professionalism" might mean; it adds specificity to such discussions by exploring a particular definition of profession, namely Freidson’s theory of professions as occupations that are in control of their own work. The study contributes to the development of theories around higher education concepts of academic professionalism and, in so doing, links that theoretical contribution to the wider professions field.

Common psychotic symptoms can be explained by the theory of ecological perception

The symptoms of psychiatric illness are diverse, as are the causes of the illnesses that cause them. Yet, regardless of the heterogeneity of cause and presentation, a great deal of symptoms can be explained by the failure of a single perceptual function – the reprocessing of ecological perception. It is a central tenet of the ecological theory of perception that we perceive opportunities to act. It has also been found that perception automatically causes actions and thoughts to occur unless this primary action pathway is inhibited. Inhibition allows perceptions to be reprocessed into more appropriate alternative actions and thoughts. Reprocessing of this kind takes place over the entire frontal lobe and it renders action optional. Choice about what action to take (if any) is the basis for the feeling of autonomy and ultimately for the sense-of-self. When thoughts and actions occur automatically (without choice) they appear to originate outside of the self, thereby providing prima facie evidence for some of the bizarre delusions that define schizophrenia such as delusional misidentification, delusions of control and Cotard’s delusion. Automatic actions and thoughts are triggered by residual stimulation whenever reprocessing is insufficient to balance automatic excitatory cues (for whatever reason). These may not be noticed if they are neutral and therefore unimportant whereas actions and thoughts with a positive bias are desirable. Responses to negative stimulus, on the other hand, are always unwelcome, because the actions that are triggered will carry the negative bias. Automatic thoughts may include spontaneous positive feelings of love and joy, but automatic negative thoughts and visualisations are experienced as hallucinations. Not only do these feel like they emerge from elsewhere but they carry a negative bias (they are most commonly critical, rude and are irrationally paranoid). Automatic positive actions may include laughter and smiling and these are welcome. Automatic behaviours that carry a negative bias, however, are unwelcome and like hallucinations, occur without a sense of choice. These include crying, stereotypies, perseveration, ataxia, utilization and imitation behaviours and catatonia.

The dynamics of individual teacher autonomy: A case study of teachers' work in a Queensland secondary school

The emphasis on collegiality and collaboration in the literature on teachers' work and school reform has tended to underplay the significance of teacher autonomy. This thesis explores the dynamics of teachers' understandings and experiences of individual teacher autonomy (as contrasted with collective autonomy) in an independent school in Queensland which promoted itself as a 'teachers' school' with a strong commitment to individual teacher autonomy. The research was a case study which drew on methodological signposts from critical, feminist and traditional ethnography. Intensive fieldwork in the school over five months incorporated the ethnographic techniques of observation, interviews and document analysis. Teachers at Thornton College understood their experience of individual autonomy at three interrelated levels--in terms of their work in the classroom, their working life in the school, and their voice in the decision-making processes of the school. They felt that they experienced a great deal of individual autonomy at each of these three levels. These understandings and experiences of autonomy were encumbered or enabled by a range of internal and external stakeholder groups. There were also a number of structural influences (community perceptions, market forces, school size, time and bureaucracy) emerging from the economic, social and political structures in Australian society which influenced the experience of autonomy by teachers. The experience of individual teacher autonomy was constantly shifting, but there were some emergent patterns. Consensus on educational goals and vision, and strong expressions of trust and respect between teachers and stakeholders in the school, characterised the contexts in which teachers felt they experienced high levels of autonomy in their work. The demand for accountability and desire for relatedness motivated stakeholders and structural forces to influence teacher autonomy. Some significant gaps emerged between the rhetoric of a commitment to individual teacher autonomy and decision-making practices in the school, that gave ultimate power to the co-principals. Despite the rhetoric and promotion of non-hierarchical structures and collaborative decision-making processes, many teachers perceived that their experience of individual autonomy remained subject to the exercise of 'partial democracy' by school leaders.

Towards a Critique of the Concept of the Right to Self-Determination in Africa : A Conceptual Examination and the Cases of Western Sahara, Southern Sudan and Eritrea

This thesis examines the right to self-determination which is a norm used for numerous purposes by multiple actors in the field of international relations, with relatively little clarity or agreement on the actual and potential meaning of the right. In international practice, however, the main focus in applying the right has been in the context of decolonization as set by the United Nations in its early decades. Thus, in Africa the right to self-determination has traditionally implied that the colonial territories, and particularly the populations within these territories, were to constitute the people who were entitled to the right. That is, self-determination by decolonization provided a framework for the construction of independent nation-states in Africa whilst other dimensions of the right remained largely or totally neglected. With the objective of assessing the scope, content, developments and interpretations of the right to self-determination in Africa, particularly with regard to the relevance of the right today, the thesis proceeds on two fundamental hypotheses. The first is that Mervyn Frost s theory of settled norms, among which he lists the right to self-determination, assumes too much. Even if the right to self-determination is a human right belonging to all peoples stipulated, inter alia, in the first Article of the 1966 International Human Rights Covenants, it is a highly politicized and context-bound right instead of being settled and observed in a way that its denial would need special justification. Still, the suggested inconsistency or non-compliance with the norm of self-determination is not intended to prove the uselessness or inappropriateness of the norm, but, on the contrary, to invite and encourage debate on the potential use and coverage of the right to self-determination. The second hypothesis is that within the concept of self-determination there are two normative dimensions. One is to do with the idea and practice of statehood, the nation and collectivity that may decide to conduct itself as an independent state. The other one is to do with self-determination as a human right, as a normative condition, to be enjoyed by people and peoples within states that supersedes state authority. These external and internal dimensions need to be seen as complementary and co-terminous, not as mutually exclusive alternatives. The thesis proceeds on the assumption that the internal dimension of the right, with human rights and democracy at its core, has not been considered as important as the external. In turn, this unbalanced and selective interpretation has managed to put the true normative purpose of the right making the world better and bringing more just polity models into a somewhat peculiar light. The right to self-determination in the African context is assessed through case studies of Western Sahara, Southern Sudan and Eritrea. The study asks what these cases say about the right to self-determination in Africa and what their lessons learnt could contribute to the understanding and relevance of the right in today s Africa. The study demonstrates that even in the context of decolonization, the application of the right to self-determination has been far from the consistent approach supposedly followed by the international community: in many respects similar colonial histories have easily led to rather different destinies. While Eritrea secured internationally recognized right to self-determination in the form of retroactive independence in 1993, international recognition of distinct Western Sahara and Southern Sudan entities is contingent on complex and problematic conditions being satisfied. Overall, it is a considerable challenge for international legality to meet empirical political reality in a meaningful way, so that the universal values attached to the norm of self-determination are not overlooked or compromised but rather reinforced in the process of implementing the right. Consequently, this thesis seeks a more comprehensive understanding of the right to self-determination with particular reference to post-colonial Africa and with an emphasis on the internal, human rights and democracy dimensions of the norm. It is considered that the right to self-determination cannot be perceived only as an inter-state issue as it is also very much an intra-state issue, including the possibility of different sub-state arrangements exercised under the right, for example, in the form of autonomy. At the same time, the option of independent statehood achieved through secession remains a mode of exercising and part of the right to self-determination. But in whatever form or way applied, the right to self-determination, as a normative instrument, should constitute and work as a norm that comprehensively brings more added value in terms of the objectives of human rights and democracy. From a normative perspective, a peoples right should not be allowed to transform and convert itself into a right of states. Finally, in light of the case studies of Western Sahara, Southern Sudan and Eritrea, the thesis suggests that our understanding of the right to self-determination should now reach beyond the post-colonial context in Africa. It appears that both the questions and answers to the most pertinent issues of self-determination in the cases studied must be increasingly sought within the postcolonial African state rather than solely in colonial history. In this vein, the right to self-determination can be seen not only as a tool for creating states but also as a way to transform the state itself from within. Any such genuinely post-colonial approach may imply a judicious reconsideration, adaptation or up-dating of the right and our understanding of it in order to render it meaningful in Africa today.
