The study examines the term "low threshold" from the point of view of the most marginalized drug users. While using illicit drugs is criminalised and morally judged in Finland, users have special barriers to seek for care. Low threshold services aim at reaching drug users who themselves don t seek for help. "Low threshold" is a metaphor describing easy access to services. The theoretical frame of reference of the study consists of processing the term analytically and critically. The research work sets out to test the rhetoric of low threshold by making use of a qualitative multi-case study to find out, if the threshold of so called low threshold services always appears low for the most marginalized drug users. The cases are: the mobile unite offering health counselling, the day service centre for marginalized substance abusers and the low threshold project of the outpatient clinic for drug users in Helsinki and the health counselling service trial in Vyborg, Russia. The case study answer following questions: 1) How do the method of low threshold work out in the studied cases from the point of view of the most marginalized drug users? 2) How do potential thresholds appear and how did they develop? 3) How do the most marginalized drug users get into the care system through low threshold? The data consists of interviews of drug users, workers and other specialists having been accomplished in the years 2001 - 2006, patient documents and customer registers. The dissertation includes four articles published in the years 2006 - 2008 and the summary article. The study manifests that even low threshold is not always low enough for the most marginalized drug users. That expresses a highly multiproblematised and underpriviledged group of drug users, whose life and utilization of services are framed by deep marginalisation, homelessness, multi-substance use, mental and somatic illnesses and being repeatedly imprisoned. Using services is rendered difficult by many factors arising from the care system, drug users themselves and the action environment. In Finland thresholds are generally due to the execution of practical services and procedures not considering the fear of control and labelling as a drug user. When striving for further rehabilitating substance abuse care by means of low threshold services the marginalized drug users meet the biggest difficulties. They are due to inelastic structures, procedures and division of labour in the established care system and also to poor chances of drug users to be in action in the way expected by the care system. Multiproblematic multisubstance users become "wrong" customers by high expectations of care motivation and specializing in the care system. In Russia the thresholds are primarily caused by rigid control politics directed to drug users by the society and by the scantiness of care system. The ideology of reducing drug related harm is not approved and the care system is unwilling to commit to it. Low threshold turnes out to be relative as a term. The rhetoric of the care system is not enough to unilaterally define lowness of the threshold. The experiences of drug users and the actual activity to search for care determine the threshold. It does not appear the same for everybody either. Access of certain customer group to a service unit may even raise the threshold for some other group. The low threshold system also is surprisingly realized: you could not always tell in advance, what kind of customers and how many of them could be reached.

Gender, Politics and Democratisation in Cameroon

Gender perceptions, religious belief systems, and political thought have excluded women from politics, for ages, around the world. Combining feminist and modernisation theorists in my theoretical framework, I examine the trends in patriarchal Europe and I highlight the gender-sensitive model of the Nordic countries. Retracing local gender patterns from precolonial to postcolonial eras in sub-Saharan Africa, I explore the links between perceptions, needs, resources, education and women's political participation in Cameroon. Democratisation is supposed to open up political participation, to grant equal opportunities to all adults. One ironic feature of the liberalisation process in Cameroon has been the decrease of women in parliamentarian representation (14% in 1988, 6% in 1992, 5% in 1997 and 10% in 2002). What social, cultural and institutional mechanisms produced this paradoxical outcome, the exclusion of half the population? The gender complementarity of the indigenous context has been lost to male prevalence privileged by education, church, law, employment, economy and politics in the public sphere; most women are marginalised in the private sphere. Nation building and development have failed; ethnicism and individualism are growing. Some hope lies in the growing civil society. From two surveys and 21 focus groups across Cameroon, in 2000 and 2002, some significant results of the processed empirical data reveal low electoral registration (34.5% women and 65.9% men), contrasted by the willingness to run for municipal elections (33.3 % women and 45.2% men). The co-existence of customary and statutory laws, the corrupt political system and fraudulent practices, contribute to the marginalisation of women and men who are interested in politics. A large majority of female respondents consider female politicians more trustworthy and capable than their male counterparts; they even foresee the appointment of a female Prime Minister. The Nordic countries have institutionalised gender equality in their legislation, policies and practices. France has improved women's political inclusion with the parity laws; Rwanda is another model of women's representation, thanks to its post-conflict constitution. From my analysis, Cameroonian institutions, men and more so women, may learn and borrow from these experiences, in order to design and implement a sustainable and gender-balanced democracy. Keywords: democratisation, politics, gender equality, feminism, citizenship, Cameroon, Nordic countries, Finland, France, United Kingdom, quotas, societal social psychology.

A Study of Practical Biological Phantoms with Simple Instrumentation for Electrical Impedance Tomography (EIT)

16-electrode phantoms are developed and studied with a simple instrumentation developed for Electrical Impedance Tomography. An analog instrumentation is developed with a sinusoidal current generator and signal conditioner circuit. Current generator is developed withmodified Howland constant current source fed by a voltage controlled oscillator and the signal conditioner circuit consisting of an instrumentation amplifier and a narrow band pass filter. Electronic hardware is connected to the electrodes through a DIP switch based multiplexer module. Phantoms with different electrode size and position are developed and the EIT forward problem is studied using the forward solver. A low frequency low magnitude sinusoidal current is injected to the surface electrodes surrounding the phantom boundary and the differential potential is measured by a digital multimeter. Comparing measured potential with the simulated data it is intended to reduce the measurement error and an optimum phantom geometry is suggested. Result shows that the common mode electrode reduces the common mode error of the EIT electronics and reduces the error potential in the measured data. Differential potential is reduced up to 67 mV at the voltage electrode pair opposite to the current electrodes. Offset potential is measured and subtracted from the measured data for further correction. It is noticed that the potential data pattern depends on the electrode width and the optimum electrode width is suggested. It is also observed that measured potential becomes acceptable with a 20 mm solution column above and below the electrode array level.

The Feminist Transformation of Bioethics : An Analysis of Theoretical Perspectives and Practical Applications in Feminist Bioethics

The purpose of this study is to examine how transformation is defining feminist bioethics and to determine the nature of this transformation. Behind the quest for transformation is core feminism and its political implications, namely, that women and other marginalized groups have been given unequal consideration in society and the sciences and that this situation is unacceptable and should be remedied. The goal of the dissertation is to determine how feminist bioethicists integrate the transformation into their respective fields and how they apply the potential of feminism to bioethical theories and practice. On a theoretical level, feminist bioethicists wish to reveal how current ways of knowing are based on inequality. Feminists pay special attention especially to communal and political contexts and to the power relations endorsed by each community. In addition, feminist bioethicists endorse relational ethics, a relational account of the self in which the interconnectedness of persons is important. On the conceptual level, feminist bioethicists work with beliefs, concepts, and practices that give us our world. As an example, I examine how feminist bioethicists have criticized and redefined the concept of autonomy. Feminist bioethicists emphasize relational autonomy, which is based on the conviction that social relationships shape moral identities and values. On the practical level, I discuss stem cell research as a test case for feminist bioethics and its ability to employ its methodologies. Analyzing these perspectives allowed me first, to compare non-feminist and feminist accounts of stem cell ethics and, second, to analyze feminist perspectives on the novel biotechnology. Along with offering a critical evaluation of the stem cell debate, the study shows that sustainable stem cell policies should be grounded on empirical knowledge about how donors perceive stem cell research and the donation process. The study indicates that feminist bioethics should develop the use of empirical bioethics, which takes the nature of ethics seriously: ethical decisions are provisional and open for further consideration. In addition, the study shows that there is another area of development in feminist bioethics: the understanding of (moral) agency. I argue that agency should be understood to mean that actions create desires.

Bullying and organisational politics in competitive and rapidly changing work environments

This paper argues that workplace bullying can in some cases be a form of organisational politics, that is, a deliberate, competitive strategy from the perspective of the individual perpetrator. A cross-sectional study conducted among business professionals revealed that there was a correlation between a politicised and competitive climate and bullying. This finding implies that globalisation, increased pressures for efficiency, and restructuring, which limits the number of management positions and thereby contributes to increased internal competition, may lead to more bullying. The findings have important implications for management, since the possible political aspects of bullying must be taken into account in order to be able to undertake successful prevention and intervention measures.

Inverted V-Notch: Practical Proportional Weir

This paper presents a practical linear proportional weir of simple geometric shape in the form of an inverted V-notch or inward trapezium. The flow through this weir, of half-width w and altitude d, for depths above 0.22d is proportional to the depth of flow measured above a reference plane situated at 0.08d for all heads in the range 0.22d<=h<=0.94d, with a maximum percentage deviation of ±1.5 from the theoretical discharge. The linear relationship between head and discharge is based on numerical optimization procedures. Nearly 75% of the depth of inverted V-notch can be used effectively as the measuring range. Experiments with four weirs, with different vertex angles, show excellent agreement with the theory by giving an average coefficient of discharge for each weir varying from 0.61–0.62.

The Far Eastern Question at the Washington Conference (1921-1922) with an outline of its implications for internal politics in China

This dissertation is a narrative account of the negotiations concerning the question of the Far East and the Shandong issue at the Washington Conference, leading to treaties, agreements and resolutions. In this dissertation, a certain stress is laid on the interaction between the Conference and the internal situation in China, particularly concerning the question of the implications of the Conference for Cabinet politics in Peking. Through the narrative account of the Conference, the general aim is an attempt to reassess the achievements of the Washington Conference. Too often the Washington Conference has been viewed negatively. The political aim behind the legal framework was to open the door to China as a sovereign State member of the international community whose territorial integrity was internationally recognized, despite its chaotic internal situation. It is undeniable that the Washington Conference opened a new chapter in modern Chinese history. The violations of the agreements concerning China that occurred in the 1930s should not lead to the belief that these agreements were of no value. Peace may not be lasting and evolves according to circumstances; agreements are transitory, and new situations need new arrangements. This dissertation tries to demonstrate that the agreements in themselves were not the cause of their failure, but the failure was due to the lack of determination on the part of the Signatories Powers to defend them.

The Politics and Policies of Reproductive Agency

This study examines the politics and policies of reproductive agency through a redescription of three Finnish policy documents dealing with the declining birth rate: the Government report on the future 'Finland for people of all ages' (2004), Business and Policy Forum EVA report 'Condemned to Diminish?' (Tuomitut vähenemään?) (2003), and the Family Federation's 'Population Policy Program' (2004). The redescription is done with the help of the notion of reproductive agency, which draws on Drucilla Cornell's concepts of the imaginary domain and bodily integrity. The imaginary domain is the moral and psychic space people need in order to form their personality, which is created in constant identificatory processes. The aim of the processes is imaginary coherence. As the personality is embodied, forming one s imaginary coherence always includes attempts for bodily integrity, also entailing attempts to arrive at an understanding of one's procreative capacities. Besides Cornell, I draw on Judith Butler's thinking and comprehend gender performatively as doing, and in relation to that agency as part of the performative process of one's personality. Reproductive agency is understood in this study as the possibilities to live differently the hegemonic forms of procreative life. I deal with three redescriptive themes: the family, economics and gender. The family is a central element in that it is considered the main location of reproduction. With regard to reproductive agency, the documents include problematic conceptions of the family. It is defined as a heterosexual, monogamous, conjugal relationship, which affects reproductive agency in that these notions do not allow for different modes of family life. The second prominent aspect, economics, features on two levels: the macroeconomic level of GDP, employment and competitiveness, and the level of family policies and concern about family finances. Macroeconomic-level argumentation is problematic in the context of reproductive agency because it implies that procreation is a duty of citizens, and thus has effects on values attached to reproductive potential. On the other hand, family policies may advance reproductive agency in supporting families financially. However, such policies also define how the family is understood, thereby affecting reproductive agency. The third theme, gender, intersects with many issues in the policy documents. All three texts consider the roles of men and women differently: women are primarily responsible for the family, and both men's and women's reproductive agency is affected in that the roles in the procreative process are predefined. EVA and the Family Federation see women as the main target of population policies, and consider it legitimate to try to change women s reproductive decisions. Implicit in the notion of reproductive agency is the idea that it should be possible to overcome and live differently the sex difference, but the three documents do not open up opportunities for that. The notion of reproductive agency makes it also possible to question the legitimacy of population policies in general and offers new perspectives on the vocabularies used in the three policy texts, providing insights into the values and logics that support the concepts.

Design of Single-Input-Single-Output Compliant Mechanisms for Practical Applications Using Selection Maps

We present an interactive map-based technique for designing single-input-single-output compliant mechanisms that meet the requirements of practical applications. Our map juxtaposes user-specifications with the attributes of real compliant mechanisms stored in a database so that not only the practical feasibility of the specifications can be discerned quickly but also modifications can be done interactively to the existing compliant mechanisms. The practical utility of the method presented here exceeds that of shape and size optimizations because it accounts for manufacturing considerations, stress limits, and material selection. The premise for the method is the spring-leverage (SL) model, which characterizes the kinematic and elastostatic behavior of compliant mechanisms with only three SL constants. The user-specifications are met interactively using the beam-based 2D models of compliant mechanisms by changing their attributes such as: (i) overall size in two planar orthogonal directions, separately and together, (ii) uniform resizing of the in-plane widths of all the beam elements, (iii) uniform resizing of the out-of-plane thick-nesses of the beam elements, and (iv) the material. We present a design software program with a graphical user interface for interactive design. A case-study that describes the design procedure in detail is also presented while additional case-studies are posted on a website. DOI:10.1115/1.4001877].

Practical Proposals for Specifying k-Nearest Neighbours Weights Matrices

In this article we introduce and evaluate testing procedures for specifying the number k of nearest neighbours in the weights matrix of spatial econometric models. The spatial J-test is used for specification search. Two testing procedures are suggested: an increasing neighbours testing procedure and a decreasing neighbours testing procedure. Simulations show that the increasing neighbours testing procedures can be used in large samples to determine k. The decreasing neighbours testing procedure is found to have low power, and is not recommended for use in practice. An empirical example involving house price data is provided to show how to use the testing procedures with real data.

Optimal Receive Antenna Selection in Time-Varying Fading Channels with Practical Training Constraints

Hardware constraints, which motivate receive antenna selection, also require that various antenna elements at the receiver be sounded sequentially to obtain estimates required for selecting the `best' antenna and for coherently demodulating data thereafter. Consequently, the channel state information at different antennas is outdated by different amounts and corrupted by noise. We show that, for this reason, simply selecting the antenna with the highest estimated channel gain is not optimum. Rather, a preferable strategy is to linearly weight the channel estimates of different antennas differently, depending on the training scheme. We derive closed-form expressions for the symbol error probability (SEP) of AS for MPSK and MQAM in time-varying Rayleigh fading channels for arbitrary selection weights, and validate them with simulations. We then characterize explicitly the optimal selection weights that minimize the SEP. We also consider packet reception, in which multiple symbols of a packet are received by the same antenna. New suboptimal, but computationally efficient weighted selection schemes are proposed for reducing the packet error rate. The benefits of weighted selection are also demonstrated using a practical channel code used in third generation cellular systems. Our results show that optimal weighted selection yields a significant performance gain over conventional unweighted selection.

Practical constant-accuracy linear weir

This paper is concerned with the modifications of the Extended Bellmouth Weir (EBM weir) earlier designed by Keshava Murthy. It is shown that by providing inclined sides (equivalent to providing an inward-trapezoidal weir) over a sector of a circle of radius R, separated by a distance 2t, and depth d, the measurable range of EBM can be considerably enhanced (over 375%). Simultaneously, the other parameters of the weir are optimized such that the reference plane of the weir coincides with its crest making it a constant-accuracy linear weir. Discharge through the aforementioned weir is proportional to the depths of flow measured above the crest of the weir for all heads in the range of 0.5R less-than-or-equal-to h less-than-or-equal-to 7.9R, within a maximum deviation of +/-1% from the theoretical discharge. Experiments with two typical weirs show excellent agreement with the theory by giving a constant-average coefficient of discharge of 0.619

The Untouchable Soldier: Caste, Politics, and the Indian Army

Military establishments are omnipresent if not everywhere omnipotent. While these costly bureaucracies are the bane of finance ministers around the world, they do provide an important opportunity for comparative analysis. This paper examines a military system—the Indian one—through time, and attempts to demonstrate the changing relationship of that system to Indian politics and society in general, and to the low-caste communities of India in particular. We select the low-caste untouchables because they represent an extreme challenge to the integrative capacity of both political and social systems, and because they have recently been the subject of intensive political and academic concern.Stephen P. Cohen is Assistant Professor of Political Science in Asian Studies at the University of Illinois.
