Is There Personal Identity in Economics?

John B. Davis explores the question of what the economic individual is. He bases his considerations of orthodox economics on the assumption that these theories implicitly rely on a conception of the individual that has its origin in Locke’s idea of the self as subjective inwardness. Economic history then is the attempt to deal with Locke’s inherent problems that this view involved. If neoclassical economics still has aspects of human psychology, mainstream economics dropped the subjective concept of the individual out of their considerations. However, Davis demonstrates that even the neoclassical concept of the individual fails to pass the existence test of individual identity. The latter is an idea developed in analogy to philosophers’ concern about personal identity and examines if the individual can be distinguished among different individuals and if he or she can be reidentified as the selfsame individual through time. The failure of the theory of the individual in orthodox economics led Davis to develop a concept of a socially embedded individual in accordance with heterodox accounts of economics. He submits this conception to the same test of individual identity. It appears that the socially embedded individual can be said to hold an identity in specific circumstances.

Uncomfortable Comparisons : The Canadian Truth And Reconciliation Commission In International Context

The Canadian Truth and Reconciliation Commission on Indian Residential Schools is a novel foray into a genre previously associated with so-called “transitional” democracies from the post-Communist world and the global South. This basic fact notwithstanding, a systematic comparison with the broader universe of truth commission-hosting countries reveals that the circumstances surrounding the Canadian TRC are not entirely novel. This article develops this argument by distilling from the transitional justice literature several bases of comparison designed to explain how a truth commission’s capacity to promote new cultures of justice and accountability in the wake of massive violations of human rights is affected by the socio-political context in which the commission occurs; the injustices it is asked to investigate; and the nature of its mandate. It concludes that these factors, compounded by considerations unique to the Canadian context, all militate against success. If Canadian citizens and policymakers fail to meet this profound ethIcal challenge, they will find themselves occupying the transition-wrecking role played more familiarly by the recalcitrant and unreformed military and security forces in the world’s more evidently authoritarian states.

Street-level labour inspection in China and the implementation of ILO Convention No.155 concerning occupational safety and health

Les relations de travail et d'emploi sont devenues des enjeux importants en Chine. La Chine a ratifié 25 conventions internationales du travail et a travaillé en étroite collaboration avec l'OIT pour améliorer la sécurité et la santé au travail. Malgré ces efforts, la Chine est souvent critiquée pour des violations du travail. Face à ces problèmes, un système législatif d'administration de travail a été développé au niveau national. Mais l’application de ces règlements demeure problématique.. En particulier, les difficultés rencontrées par les inspecteurs du travail dans l'application de ces lois constituent un élément clé du problème. Notre mémoire s'intéresse essentiellement au rôle de l'inspecteur du travail dans l'administration publique de la sécurité du travail en Chine. Ces fonctionnaires jouent un rôle important et peuvent parfois exercer leur discrétion en tant qu'acteurs de première ligne, faisant d'eux de vrais décideurs politiques. Par conséquent, la compréhension de leur rôle et de leur discrétion dans l'application des normes du travail en Chine est cruciale. Notre mémoire est centré sur une étude de cas qualitative d'un bureau d'inspection du travail dans la région de Beijing. Dans le cadre de notre recherche nous avons examiné le rôle des inspecteurs du travail au moyen d’entretiens semi-structurés, d’une recherche documentaire ainsi qu’à l’occasion d’une brève observation des inspecteurs sur lors de la visite d’un lieu de travail. Les résultats démontrent que la définition du pouvoir discrétionnaire des inspecteurs du travail de première ligne en Chine est un enjeu très complexe. L’étude de cas permet cependant d’élaborer un cadre permettant l’identification des facteurs critiques déterminants pour l'évaluation et la compréhension de la nature du pouvoir discrétionnaire de l'inspecteur du travail en application de la loi.

Natural air conditioning, traditions and trends : high performance of sustainable indoor ventilation in a hot and dry climate

De nos jours, l'utilisation accrue de combustibles à base de fossiles et l'électricité met en péril l'environnement naturel à cause des niveaux élevés de pollution. Il est donc plausible de prévoir des économies d'énergie significatives grâce à la climatisation dite «naturelle»». En accord avec les objectifs acceptés à l'échelle internationale d'une architecture «verte» et durable, l'utilisation de cours intérieures associées aux capteurs de vent, aux murs-Trombe et à d'autres systèmes de climatisation naturelle (aussi bien traditionnels que nouveaux), paraît prometteuse. Ce mémoire propose une analyse de nouvelles approches à la climatisation naturelle et à la production d'air frais avec une consommation minimale d'énergie, eu égard aux traditions et aux tendances, en particulier dans les zones climatiques chaudes et sèches comme l'Iran. Dans ce contexte, regarder l'architecture de l'Islam et la discipline du Qur'an paraissent offrir un guide pour comprendre l'approche musulmane aux processus de décision en design. Nous regardons donc les traditions et les tendances en ce qui concerne la climatisation naturelle à travers l'élément le plus important du contexte islamique, à savoir le Qur'an. C'est pourquoi, à l'intérieur du thème de la tradition, nous avons pris en compte quelques considérations concernant l'influence de l'Islam, et en particulier le respect de la nature associé à un équilibre entre l'harmonie et l'individualité. Ce sont autant de facteurs qui influencent la prise de décisions visant à résoudre des problèmes scientifiques majeurs selon la philosophie et les méthodes islamiques ; ils nous permettent de faire quelques recommandations. La description des principes sous-jacents aux capteurs à vent et des antécédents trouvés dans la nature tels que les colonies de termites, est présentée également. Sous la rubrique tendances, nous avons introduit l'utilisation de matériaux et de principes de design nouveaux. Regarder simultanément ces matériaux nouveaux et l'analogie des colonies de termites suggère de bonnes approches à la conception d'abris pour les victimes de tremblements de terre dans les régions sisimques. Bam, une ville iranienne, peut être considérée comme un exemple spécifique illustrant où les principes exposés dans ce mémoire peuvent s'appliquer le plus adéquatement.

Privacy in Bitcoin through decentralized mixers

Dans les crypto-monnaies telles Bitcoin, l’anonymité des utilisateurs peut être compromise de plusieurs façons. Dans ce mémoire, nous effectuons une revue de littérature et une classification des différents protocoles existants pour anonymiser les usagers et analysons leur efficacité. S’appuyant sur certains critères désirables dans de tels protocoles, nous proposons un modèle de mixeur synchrone décentralisé. Nous avons ciblé deux approches qui s’inscrivent dans ce modèle, le plan de transaction et le réseau de transactions, le second étant une contribution originale de ce mémoire. Nous expliquons son fonctionnement puis analysons son efficacité dans le contexte actuel d’utilisation de Bitcoin

La notion de bonne foi dans les immunités législatives au Québec : entre imprécision et redondance

Les immunités législatives pour bonne foi sont une composante importante des règles spécifiques s’appliquant à la responsabilité civile des administrations publiques. Apparues dans les années 1940 au Québec, elles visent à insuffler à la responsabilité civile les considérations propres à l’action étatique (difficulté des tâches, pouvoir discrétionnaire, liberté d’action, etc.). Or, la notion principale de ces immunités, la bonne foi, est d’une nature fragile. Tiraillée entre une vision subjective et objective, elle souffre de nombreuses lacunes. Originalement fondée sur l’évaluation de l’état d’esprit d’une personne, la bonne foi reproduit dorénavant le concept de faute lourde présent en responsabilité civile. Il en résulte un système qui crée de la confusion sur l’état mental nécessaire pour entrainer la responsabilité d’une administration publique. Au surplus, le régime de la bonne foi est variable et change selon les fonctions exercées par les administrations publiques. Ces attributs mettent en exergue le peu d’utilité de cette notion : la bonne foi dédouble plusieurs éléments déjà présents en responsabilité civile québécoise et partant de là, affaiblit sa place comme règle particulière applicable aux administrations publiques. Bref, par son caractère adaptable, la bonne foi est un calque de la responsabilité civile québécoise et son faible apport embrouille le régime de cette dernière.

Design Considerations of Sonar Projector Arrays with Improved Performance

Systems which employ underwater acoustic energy for observation or communication are called sonar systems. The active and passive sonars are the two types of systems used for the detection and localisation of targets in underwater. Active sonar involves the transmission of an acoustic signal which, when reflected from a target, provides the sonar receiver with a basis for the detection and estimation. Passive sonar bases its detection and estimation on sounds which emanate from the target itself--Machinery noise, flow noise, transmission from its own active sonar etc.Electroacoustic transducers are used in sonar systems for the transmission and detection of acoustic energy. The transducer which is used for the transmission of acoustic energy is called projector and the one used for reception is called hydrophone. Since a single transducer is not sufficient enough for long range and directional transmission, a properly distributed array of transducers are to be used [9-11].The need and requirement for spatial processing to generate the most favourable directivity patterns for transducer systems used in underwater applications have already been analysed by several investigators [12-21].The desired directivity pattern can be either generated by the use of suitable focussing techniques or by an array of non-directional sensor elements, whose arrangements, spacing and the mode of excitation provide the required radiation pattern or by the combination of these.While computing that the directivity pattern, it is assumed strength of the elements are unaffected by the the source acoustic pressure at each source. However, in closely packed a r r a y s , the acoustic interaction effects experienced among the elements will modify the behaviour of individual elements and in turn will reduce the acoust ic source leve 1 wi t h respect to the maximum t heoret i cal va 1ue a s well as degrade the beam pa t tern. Th i s ef fect shou 1d be reduced in systems that are intended to generate high acoustic power output and unperturbed beam patterns [2,22-31].The work herein presented includes an approach for designing efficient and well behaved underwater transd~cer arrays, taking into account the acoustic interaction effect experienced among the closely packed multielement arrays.Architectural modifications reducing the interaction effect different radiating apertures.

Studies on new processing aids and other compounding ingredients in special purpose rubbers

In the first part of the study we probed the effectiveness of rice bran oil as a multipurpose compounding ingredient for nitrile (NBR) and chloroprene (CR) rubbers. This oil has already been successfully employed in the compounding of NR and SBR in this laboratory.In this context we thought it worthwhile to try this oil in the polar rubbers viz, NBR and CR also. The principle of like dissolves like as applicable to solvents is equally applicable while selecting a plasticiser, elastomer combination. Because of the compatibility considerations polar plasticisers are preferred for polar rubbers like NBR and CR. Although plasticisation is a physical phenomenon and no chemical reaction is involved, the chemical structure of plasticisers determines how much physical attraction there is between the rubber and the plasticiser. In this context it is interesting to note that the various fatty acids present in rice bran oil have a long paraffinic chain, characteristic of waxes, with an acid group at the end of the molecule. The paraffinic end of the molecule contributes lubricating effects and limits compatibility whereas the acid end group contributes some polarity and is also chemically reactive. Because of absorption of acid group on the surface of pigments, these acids will have active pigment wetting characteristics also. These factors justifies the role of rice bran oil as a co-activator and lubricating agent for NBR and CR. In fact in our study we successfully replaced stearic acid as co-activator and aromatic oillDOP as processing aid for CR and NBR with rice bran oil.This part of the study has got special significance in the fact that rubber industry now heavily depends on petroleum industry for process oils. The conventional process oils like aromatic, naphthenic and paraffinic oils are increasingly becoming costlier, as its resources in nature are fast depleting. Moreover aromatic process oils are reported to be carcinogenic because of the presence of higher levels of polycyclic aromatic compounds in these oils.As a result of these factors, a great amount research is going on world over for newer processing aids which are cost effective, nontoxic and performanance wise at par with the conventional ones used in the rubber industry. Trials with vegetable oils in this direction is worth trying.Antioxidants are usually added to the rubber compound to minimise ageing effects from heat, light, oxygen etc. As rice bran oil contains significant amount of tocopherols and oryzanol which are natural antioxidants, we replaced a phenolic antioxidant like styrenated phenol (SP) from the compound recipe of both the rubbers with RBO and ascertained whether this oil could function in the role of antioxidant as well.Preparation and use of epoxidised rice bran oil as plasticiser has already been reported.The crude rice bran oil having an iodine value of 92 was epoxidised in this laboratory using peracetic acid in presence of sulphuric acid as catalyst. The epoxy content of the epoxidised oil was determined volumetrically by treating a known weight of the oil with excess HCI and back titrating the residual HCI with standard alkali solution. The epoxidised oil having an epoxy content of 3.4% was tried in the compounding of NBR and CR as processing aids. And results of these investigations are also included in this chapter. In the second part of the study we tried how RBO/ERBO could perform when used as a processing aid in place of aromatic oil in the compounding of black filled NRCR blends. Elastomers cannot have all the properties required for a particular applications, so it is common practice in rubber industry to blend two elastomers to have desired property for the resulting blend.In this RBO/ERBO was tried as a processing aid for plasticisation, dispersion of fillers, and vulcanisation of black filled NR-CR blends.Aromatic oil was used as a control. The results of our study indicate that these oils could function as a processing aid and when added together with carbon black function as a cure accelerator also.PVC is compatible with nitrile rubber in all proportions, provided NBR has an acrylonitrile content of 25 to 40%. Lower or higher ACN content in NBR makes it incompatible with PVC.PVC is usually blended with NBR at high temperatures. In order to reduce torque during mixing, additional amounts of plasticisers like DOP are added. The plasticiser should be compatible both with PVC and NBR so as to get a homogeneous blend. Epoxidised soyaben oil is reported to have been used in the compounding of PVC as it can perfonn both as an efficient plasticiser and heat stabilizer.At present DOP constitute the largest consumed plasticiser in the PVC compounding. The migration of this plasticiser from food packaging materials made of PVC poses great health hazards as this is harmful to human body. In such a scenario we also thought it worthwhile to see whether DOP could be replaced by rice bran oil in the compounding of NBR-PVC blends Different blends of NBR-PVC were prepared with RBO and were vulcanized using sulphur and conventional accelerators. The various physical and mechanical properties of the vulcanisates were evaluated and compared with those prepared with DOP as the control plasticiser. Epoxidised rice bran oil was also tried as plasticiser for the preparation of NBR-PVC blends. A comparison of the processability and cure characteristics of the different blends prepared with DOP and ERBO showed that ERBO based blends have better processability and lower cure time values. However the elastographic maximum torque values are higher for the DOP based blends. Almost all of the physical properties evaluated are found to be slightly better for the DOP based blends over the ERBO based ones. However a notable feature of the ERBO based blends is the better percentage retention of elongation at break values after ageing over the DOP based blends. The results of these studies using rice bran oil and its epoxidised variety indicated that they could be used as efficient plasticisers in place of DOP and justifies their role as novel, nontoxic, and cheap plasticisers for NBR-PVC blends.

Phase synchronization in an array of driven Josephson junctions

We consider an array of N Josephson junctions connected in parallel and explore the condition for chaotic synchronization. It is found that the outer junctions can be synchronized while they remain uncorrelated to the inner ones when an external biasing is applied. The stability of the solution is found out for the outer junctions in the synchronization manifold. Symmetry considerations lead to a situation wherein the inner junctions can synchronize for certain values of the parameter. In the presence of a phase difference between the applied fields, all the junctions exhibit phase synchronization. It is also found that chaotic motion changes to periodic in the presence of phase differences.

The economics of tea plantations in South India

Thc tea industry in lndia is going through a period of crisis. The crisis in brought about mainly by cost caculation and declining or stagnant prices. The impact of the present crisis is felt most by the owners of tea plantations in Kcrala . The present study assumes significance due to the fact that the critic which already affected Keralas tea industry is now threatening to extend to other tea-growing areas in south India. Today, ensuring a favourablc price to the producers via-a-via possibilities or reducing the cost of production through increase in productivity of land and labour are the main considerations. The main purpose of the study is to analyse the factors behind the crisis as well as exploring immediate and long-term measures for the sustained growth of the industry.

A Novel Cache Resolution Technique For Cooperative Caching In Wireless Mobile Networks

Cooperative caching is used in mobile ad hoc networks to reduce the latency perceived by the mobile clients while retrieving data and to reduce the traffic load in the network. Caching also increases the availability of data due to server disconnections. The implementation of a cooperative caching technique essentially involves four major design considerations (i) cache placement and resolution, which decides where to place and how to locate the cached data (ii) Cache admission control which decides the data to be cached (iii) Cache replacement which makes the replacement decision when the cache is full and (iv) consistency maintenance, i.e. maintaining consistency between the data in server and cache. In this paper we propose an effective cache resolution technique, which reduces the number of messages flooded in to the network to find the requested data. The experimental results gives a promising result based on the metrics of studies.

Arbeitszeitflexibilisierung in der westdeutschen Metall- und Elektroindustrie und die Verbandsstrategien - Eine vergleichende Analyse der arbeitszeitpolitischen Strategien des Arbeitgeberverbandes Gesamtmetall und der Industriegewerkschaft Metall

Arbeitszeitpolitik und Arbeitszeitgestaltung haben seit dem Tarifkompromiss im Jahre 1984 in der Metall-, und Elektroindustrie in der politischen und wissenschaftlichen Diskussion einen immensen Bedeutungszuwachs erfahren. Die Forderungen nach einer flexibleren Arbeitszeitgestaltung haben zeitgleich sowohl aus der Globalisierungsdiskussion und der Debatte um die Wettbewerbsfähigkeit des "Wirtschaftsstandorts Deutschland" heraus wie auch aus beschäftigungspolitischen Gründen neuen Auftrieb bekommen. Die Diskussion um die Arbeitszeit ist gleichzeitig von verschiedenen, meist gegensätzlichen Interessen geprägt: Auf der Beschäftigtenseite zielt die Arbeitszeitflexibilisierung nach wie vor auf Zeitsouveränität: d.h. auf eine bessere Vereinbarkeit der Arbeitszeit mit allen Aktivitäten außerhalb der Arbeitszeit ab. Demgegenüber stellt die Arbeitgeberseite den betriebswirtschaftlichen Aspekt in den Vordergrund. D.h. die Anpassung der Arbeitszeit an den tatsächlichen Arbeitsanfall. So soll durch aufeinander abgestimmte Gestaltung von Betriebszeit und Arbeitszeit die Erhöhung der Produktivität und die Sicherung der Wettbewerbsfähigkeit erzielt werden. Durch diesen Trend verlor das sog. Normalarbeitsverhältnis an Allgemeingültigkeit und die Flexibilisierung der Arbeitszeiten nahm seit langem kontinuierlich zu. Folge ist, dass mittlerweile eine breite Palette von Arbeitszeitmodellen existiert, in denen die gesetzlich und vertraglich vereinbarte Wochenarbeitszeit in den Dimensionen Lage, Länge und Verteilung flexibilisiert wird. Auch die Tarifverhandlungen und Auseinandersetzung der Tarifparteien zur Arbeitszeitpolitik sind dadurch gekennzeichnet, dass die Arbeitszeitflexibilisierung und Verlagerung der Tarifpolitik auf betriebliche Ebene einen Bedeutungszuwachs bekam und die Meinungsführerschaft in Sachen Arbeitszeitgestaltung von der IG Metall zu Gesamtmetall wechselte. Ziel der vorliegenden Dissertation war es, anhand einer empirisch-historischen Untersuchung über Einstellungen sowie Strategien von Gesamtmetall und IG Metall die Gestaltungsspielräume flexibler Arbeitszeitmodelle zu bestimmen und gleichzeitig die Defizite herauszuarbeiten. Die Untersuchung gründete sich in erster Linie auf die Dokumentenanalyse von Stellungnahmen der Gesamtmetall und IG-Metall-Leitungsgremien sowie Primär- und Sekundäranalyse von Befragungen der Beschäftigten. Die leitende Frage der Untersuchung war, ob es den Arbeitgeberverbänden und den Gewerkschaften gelingen konnte, die Erfordernisse eines Betriebes und die Belange der Beschäftigten weitgehend in Übereinstimmung zu bringen? Und (wenn ja) unter welchen Voraussetzungen die neuen flexiblen Arbeitszeitsysteme mit den betrieblichen und außerbetrieblichen Interessen der Beschäftigten zu vereinbaren sind. Den Hintergrund für diese Zielerreichung bildete der gesellschaftliche Konflikt zwischen Arbeit und Kapital. Denn die Schwierigkeit bzw. Komplexität lag in der Frage, wie die unterschiedlichen Interessen, die sich in der industriekapitalistischen Gesellschaft durch den Gegensatz "Kapital" und "Arbeit" bestimmen lassen, zu vereinbaren waren bzw. sind.
