Characterization of vertical Mo/diamond Schottky barrier diode from non-ideal I-V and C-V measurements based on MIS model

In this study, we investigated non-ideal characteristics of a diamond Schottky barrier diode with Molybdenum (Mo) Schottky metal fabricated by Microwave Plasma Chemical Vapour Deposition (MPCVD) technique. Extraction from forward bias I-V and reverse bias C- 2-V measurements yields ideality factor of 1.3, Schottky barrier height of 1.872 eV, and on-resistance of 32.63 mö·cm2. The deviation of extracted Schottky barrier height from an ideal value of 2.24 eV (considering Mo workfunction of 4.53 eV) indicates Fermi level pinning at the interface. We attributed such non-ideal behavior to the existence of thin interfacial layer and interface states between metal and diamond which forms Metal-Interfacial layer-Semiconductor (MIS) structure. Oxygen surface treatment during fabrication process might have induced them. From forward bias C-V characteristics, the minimum thickness of the interfacial layer is approximately 0.248 nm. Energy distribution profile of the interface state density is then evaluated from the forward bias I-V characteristics based on the MIS model. The interface state density is found to be uniformly distributed with values around 1013 eV - 1·cm- 2. © 2013 Elsevier B.V.

The State, Compartmentalization and the Turn to Local Community: A Critique of the Political Thought of Alasdair MacIntyre

Alasdair MacIntyre condemns modern politics, specifically liberalism and the institutions of the liberal state, as irredeemably fallen. His core argument is that the liberal state encourages a disempowering ‘compartmentalization’ of people’s everyday roles and activities that undermines the intersubjective conditions of human flourishing. MacIntyre’s alternative is an Aristotelian politics centred on the notion of “practice.” Defined by justice and solidarity, this politics can only be realized, he claims, within local communities which oppose and resist the dictates of the administrative state and capitalist market. Here it is argued that MacIntyre’s notion of “practice” represents a compelling ethical-political ideal. However, the belief that this ideal is best realized within local communities is rejected. In privileging local community, MacIntyre relies on a reductive view of modern states and overlooks the institutional conditions of a just polity. Against this, it is argued that a politics of human flourishing cannot succeed without an emancipatory transformation of large-scale, trans-communal institutions, in particular the state.

Multi-zone TAP-reactors theory and application - IV. Ideal and non-ideal boundary conditions

We study the influence of non-ideal boundary and initial conditions (BIC) of a temporal analysis of products (TAP) reactor model on the data (observed exit flux) analysis. The general theory of multi-response state-defining experiments for a multi-zone TAP reactor is extended and applied to model several alternative boundary and initial conditions proposed in the literature. The method used is based on the Laplace transform and the transfer matrix formalism for multi-response experiments. Two non-idealities are studied: (1) the inlet pulse not being narrow enough (gas pulse not entering the reactor in Dirac delta function shape) and (2) the outlet non-ideality due to imperfect vacuum. The effect of these non-idealities is analyzed to the first and second order of approximation. The corresponding corrections were obtained and discussed in detail. It was found that they are negligible. Therefore, the model with ideal boundary conditions is proven to be completely adequate to the description and interpretation of transport-reaction data obtained with TAP-2 reactors.

Irish language education and the national ideal: The dynamics of nationalism in Northern Ireland

Since the beginning of the Northern Ireland conflict in the late 1960s, Irish nationalism has been identified as a prominent force in the political culture of the state. Recent studies have suggested, however, that the ‘Nationalist’ population has become increasingly content within the new political framework created by the peace process and the aspiration for Irish unity diminished. In placing the Northern Ireland situation within the theoretical framework of nationalism, this paper will analyse how these changing priorities have been possible. Through an analysis of Irish language study in Northern Ireland's schools, the paper will examine how the political ideals espoused by the nationalist Sinn Féin Party reflected the priorities of the ‘nationalist community’. It will be contended that the relationship between the ideology and ‘the people’ is much more complex than is often allowed for and that educational inequalities are a significant contributing factor to this.

Ideal Body Size as a Mediator for the Gender-Specific Association Between Socioeconomic Status and Body Mass Index: Evidence From an Upper-Middle-Income Country in the African Region.

While obesity continues to rise globally, the associations between body size, gender, and socioeconomic status (SES) seem to vary in different populations, and little is known on the contribution of perceived ideal body size in the social disparity of obesity in African countries. We examined the gender and socioeconomic patterns of body mass index (BMI) and perceived ideal body size in the Seychelles, a middle-income small island state in the African region. We also assessed the potential role of perceived ideal body size as a mediator for the gender-specific association between SES and BMI. A population-based survey of 1,240 adults aged 25 to 64 years conducted in December 2013. Participants' BMI was calculated based on measured weight and height; ideal body size was assessed using a nine-silhouette instrument. Three SES indicators were considered: income, education, and occupation. BMI and perceived ideal body size were both higher among men of higher versus lower SES (p< .001) but lower among women of higher versus lower SES (p< .001), irrespective of the SES indicator used. Multivariate analysis showed a strong and direct association between perceived ideal body size and BMI in both men and women (p< .001) and was consistent with a potential mediating role of perceived ideal body size in the gender-specific associations between SES and BMI. Our study emphasizes the importance of gender and socioeconomic differences in BMI and ideal body size and suggests that public health interventions that promote perception of healthy weight could help mitigate SES-related disparities in BMI.

El ideal administrativo, nueva visión de la gestión directiva

Las recientes crisis económicas que ha vivido el mundo nos llevan a hacer una reflexión en torno a las responsabilidades que tienen los dirigentes empresariales en los cambios económicos e incluso sociales que se están viviendo. Es por tanto el momento para hacer un análisis más profundo del aporte que la administración, como ciencia, ha hecho a la sociedad. Se ha identificado que la administración permite el desarrollo y crecimiento de un individuo, al tiempo que es un medio de crecimiento y desarrollo para una comunidad, una región y una cultura, lo que se convierte en una realidad indiscutible que nos lleva a reflexionar acerca del porqué, ocurren problemas como las quiebras, ausencia de recursos, y conflictos internos en las organizaciones. En esa medida, una reflexión puede ser que los ideales que ha venido liderando la administración han sido desvirtuados y apartados de una moral y ética empresarial que permita al directivo pensar en algo más que utilidades. Podría parecer extraño decir que la empresa y la acción gerencial deben ir más allá. Podríamos iniciar con el análisis de la obsolescencia de los ideales administrativos o incluso en la ausencia de ideales en la administración. Sobre si se está teniendo en cuenta que la administración que conocemos y aprendemos sigue vigente en un mundo que ha evolucionado y cambiado, el mundo de hoy es distinto al que conocimos incluso en nuestra época de formación profesional, pues se nos enseñó a pensar linealmente, causa y efecto, todo cumple un orden y un plan predeterminado, hoy la visión de certidumbre y control del hombre sobre las decisiones son guiadas por el azar, y por más que el hombre trabaja y diseña estrategias, éstas serán transformadas de acuerdo a las emergencias. Por lo anterior, es importante entender que para avanzar y dejar la obsolescencia en los ideales que ha definido la administración, los directivos deben cambiar su visón y entender la dinámica de interrelación de sus organizaciones en un mundo en permanente caos. Debemos estudiar desde dinámicas diferentes a la de funcionalidad, y saber que es momento para que la administración tenga una nueva visión de la gestión administrativa, por lo que debemos ampliar nuestro horizonte y ver a través de la complejidad. Las decisiones que toman los directivos, las estrategias que definen y la forma de relacionarse con la competencia en mercados altamente competitivos requiere de un cambio en la administración y de un marco ético muy distinto, debe concebirse la gestión directiva y administrativa para mantener y conservar la vida del sector, de la empresa y, por ende, mantener el medio que nos rodea. Por ello se propone ejercer la administración desde la bioética.

The French Constitutional Council as the Rottweiler of the Republican Ideal in the Language Field: Does Jurisprudence Really Reflect Reality? EDAP 03/2012, 2012

France is known for being a champion of individual rights as well as for its overt hostility to any form of group rights. Linguistic pluralism in the public sphere is rejected for fear of babelization and Balkanization of the country. Over recent decades the Conseil Constitutionnel (CC) has, together with the Conseil d’État, remained arguably the strongest defender of this Jacobin ideal in France. In this article, I will discuss the role of France’s restrictive language policy through the prism of the CC’s jurisprudence. Overall, I will argue that the CC made reference to the (Jacobin) state-nation concept, a concept that is discussed in the first part of the paper, in order to fight the revival of regional languages in France over recent decades. The clause making French the official language in 1992 was functional to this policy. The intriguing aspect is that in France the CC managed to standardise France’s policy vis-à-vis regional and minority languages through its jurisprudence; an issue discussed in the second part of the paper. But in those regions with a stronger tradition of identity, particularly in the French overseas territories, the third part of the paper argues, normative reality has increasingly become under pressure. Therefore, a discrepancy between the ‘law in courts’ and the compliance with these decisions (‘law in action’) has been emerging over recent years. Amid some signs of opening of France to minorities, this contradiction delineates a trend that might well continue in future.

Vertical toleration as a liberal ideal

This paper argues that the direct, vertical toleration of certain types of citizen by the Rawlsian liberal state is appropriate and required in circumstances in which these types of citizen pose a threat to the stability of the state. By countering the claim that vertical toleration is redundant given a commitment to the Rawlsian version of the liberal democratic ideal, and by articulating a version of that ideal that shows this claim to be false, the paper reaffirms the centrality of vertical toleration in the Rawlsian liberal account of state-citizen relations.

Cell activation state influences the modulation of HLA-DR surface expression on human monocytes/macrophages by parenteral fish oil lipid emulsion

Abnormal surface expression of HLA-DR by leukocytes is associated with a poor prognosis in critical care patients. Critical care patients often receive total parenteral nutrition with lipid emulsion (LE). In this study we evaluated the influence of fish oil LE (FO) on human monocyte/macrophage (M phi) expression of surface HLA-DR under distinct activation states. Mononuclear leukocytes from the peripheral blood of healthy volunteers (n = 18) were cultured for 24 hours without LE (control) or with 3 different concentrations (0.1, 0.25, and 0.5%) of the follow LE: a) pure FO b) FO in association (1:1 v/v) with LE composed of 50% medium-chain trygliceride and 50% soybean oil (MCTSO), and c) pure MCTSO. The leukocytes were also submitted to different cell activation states, as determinate by INF-gamma addition time: no INF-gamma addition, 18 hours before, or at the time of LE addition. HLA-DR expression on M phi surface was evaluated by flow cytometry using specific monoclonal antibodies. In relation to controls (for 0.1%, 0.25%, and 0.5%: 100) FO decreased the expression of HLA-DR when added alone [in simultaneously-activated M phi, for 0.1%: 70 (59 +/- 73); for 0.25%: 51 (48 +/- 56); and for 0.5%: 52.5(50 +/- 58)] or in association with MCTSO [in simultaneously-activated M phi, for 0.1%: 50.5 (47 +/- 61); for 25%: 49 (45 +/- 52); and for 05 %: 51 (44 +/- 54) and in previously-activated M phi, for 1.0 % : 63 (44 +/- 88); for 0.25%: 70 (41 +/- 88); and for 0.5%: 59.5 (39 +/- 79)] in culture medium (Friedman p<0.05). In relation to controls (for 0.1%, 0.25%, and 0.5%: 100), FO did not influence the expression of these molecules on non-activated M phi [for 0.1 % : 87.5 (75 +/- 93); for 0.25%: 111 (98 +/- 118); and for 0.5%: 101.5 (84 +/- 113)]. Results show that parenteral FO modulates the expression of HLA-DR on human M phi surface accordingly to leukocyte activation state. Further clinical studies evaluating the ideal moment of fish oil LE infusion to modulate leukocyte functions may contribute to a better understanding of its immune modulatory properties.

Quasi-perfect state transfer in a bosonic dissipative network

In this paper we propose a scheme for quasi-perfect state transfer in a network of dissipative harmonic oscillators. We consider ideal sender and receiver oscillators connected by a chain of nonideal transmitter oscillators coupled by nearest-neighbour resonances. From the algebraic properties of the dynamical quantities describing the evolution of the network state, we derive a criterion, fixing the coupling strengths between all the oscillators, apart from their natural frequencies, enabling perfect state transfer in the particular case of ideal transmitter oscillators. Our criterion provides an easily manipulated formula enabling perfect state transfer in the special case where the network nonidealities are disregarded. We also extend such a criterion to dissipative networks where the fidelity of the transferred state decreases due to the loss mechanisms. To circumvent almost completely the adverse effect of decoherence, we propose a protocol to achieve quasi-perfect state transfer in nonideal networks. By adjusting the common frequency of the sender and the receiver oscillators to be out of resonance with that of the transmitters, we demonstrate that the sender`s state tunnels to the receiver oscillator by virtually exciting the nonideal transmitter chain. This virtual process makes negligible the decay rate associated with the transmitter line at the expense of delaying the time interval for the state transfer process. Apart from our analytical results, numerical computations are presented to illustrate our protocol.

DEN KOMMUNALA FÖRVALTNINGENSOM RATIONALISTISKT IDEAL- en fallstudie om styrning och handlingsutrymme inom skola,barnomsorg och miljö- och hälsoskydd

DEN KOMMUNALA FÖRVALTNINGEN SOM RATIONALISTISKT IDEAL - en fallstudie om styrning och handlingsutrymme inom skola, barnomsorg och miljö- och hälsoskydd.(The municipal authority as a rationalist ideal - a case-study on steering and scope for initiative within child-care, education and environmental departments.)A municipal authority is a considerable producer of services in the local community and iscommonly perceived as an important sector of the Swedish welfare system. One aspect of awell-functioning municipal organisation is that its administrative organs function efficiently.This study examines how activities in municipal administration are steered. The focus is on how different methods are used within a vertical hierarchical perspective to influence the actions of the participants and how the latter try to create space for action. To analyse the problem an ideal-type steering model is used.The study consists of three sections. In the first the research problem and the aims of the study are introduced as well as the methodological and theoretical approach. The result of the study is presented in the second section and in the third conclusions are drawn and discussed.The study shows that the perceptions of the participants involved regarding the possibilities of steering the everyday activities with the support of the methods studied differ on a number of points depending on the sector studied. When control of the various steering methods is distributed in different organisational units in the municipality a number of steering mechanisms operate side-by-side, sometimes in harmony and sometimes independently or in pure conflict with their goals. Steering leads to clear restrictions but there is clearlyroom for initiative, a ‘free-zone’ where the individual has room to act independently. Is it possible based on this study to state whether the ideal-type model functions in the way intended? On many accounts it would seem doubtful whether the effects of steering lead to beneficial effects for the activity. Rather it would seem that the effects of steeringsometimes function more or less randomly because the administration exists in a complexcontext in which the staff can be expected to have its own expectations and act in accordancewith them.

A dupla conversão: do ideal socialista ao estatismo e deste ao capitalismo

The new developmentalism as a weberian ideal type

New developmentalism may be seen as a specific set of policies (a national development strategy), or as a broader the theory behind (structuralist development economics) and the corresponding developmental state. Seen in the later sense, as Weberian ideal type, this paper compares new developmentalism with old developmentalism and with liberal orthodoxy. This paper was written in honor of Roberto Frenkel, in 70 years Festrischt.
