    THE THERAPEUTIC EXCEPTION: ABORTION, STERILIZATION AND MEDICAL NECESSITY IN COSTA RICA

    DEVELOPING WORLD BIOETHICS, Issue 2 2007
    MARÍA CARRANZA
    ABSTRACT Based on the case of Rosa, a nine-year-old girl who was denied a therapeutic abortion, this article analyzes the role played by the social in medical practice. For that purpose, it compares the different application of two similar pieces of legislation in Costa Rica, where both the practice of abortion and sterilization are restricted to the protection of health and life by the Penal Code. As a concept subject to interpretation, a broad conception of medical necessity could enable an ample use of the therapeutic exception and a liberal use of both surgeries. The practice of therapeutic sterilization has been generalized in Costa Rica and has become the legitimate way to distribute contraceptive sterilization. In contrast, therapeutic abortion is very rarely practiced. The analysis carried out proposes that it is the difference in social acceptance of abortion and sterilization that explains the different use that doctors, as gatekeepers of social morality, make of medical necessity.

    Sweet Necessities: Food, Sex, and Saint Augustine

    JOURNAL OF RELIGIOUS ETHICS, Issue 1 2001
    Gilbert Meilaender
    Central to Augustine's understanding of rightly ordered sexuality is his belief that the pleasure of the act should not be separated from its good (procreation). It is useful to observe that he reasons in a similar way about eating: that the pleasure of eating should not be separated from its good (nourishment). Inadequacies in his understanding of the purpose of food and eating may be instructive when we think about inadequacies in his understanding of sex. If there is more to food than he imagines, the same may be true of sex. Correcting for such inadequacies may also help correct for the (inadvertent) way in which his understanding of the purpose of sex may seem to legitimize technologies of assisted reproduction.

    Necessities of Origin and Constitution

    PHILOSOPHICAL INVESTIGATIONS, Issue 1 2010
    Derek A. McDougall
    The once deeply held conviction that all necessary truths are known a priori is now widely, although by no means universally agreed to have been subjected to penetrating, if not devastating criticism. Scott Soames, for example, on behalf of Saul Kripke, and indirectly of Hilary Putnam, argues that in respect of natural kinds, the introduction of basic essentialist assumptions grounded in our pre-theoretical habits of thinking and speaking , for example, that atomic or molecular structure provides the underlying essence of a substance , allows a sentence like "water = H20," in which the identity sign is flanked by rigid designators to express a metaphysically necessary truth. Yet doubts and puzzlement remain over the status of a posteriori necessities, including those relating to an individual's origin. This paper considers some prominent criticisms that have been made of the Kripke,Putnam approach by A. J. Ayer and Frank Ebersole among others and reveals in what respects they are valid, where they are misplaced, and, perhaps more importantly, why the most valuable aspect of this approach can be seen to reflect aspects of our scientific procedures that do indeed point towards an application for a distinction that roughly mirrors that between epistemic and metaphysical possibility, yet one that is grounded instead in the nature of our actual practices.

    Necessity to establish new risk assessment and risk communication for human fetal exposure to multiple endocrine disruptors in Japan

    CONGENITAL ANOMALIES, Issue 2 2002
    Emiko Todaka
    ABSTRACT, Our recent study clearly shows that fetuses are exposed to multiple chemicals including endocrine disruptors in Japan. Although the embryo and fetus stages are the most sensitive period to chemicals in humans' life cycle, the health effects of the chemicals such as endocrine disruptors to them are largely unknown. The conventional risk assessment method cannot assess the risk to fetuses precisely. Now we need a new risk assessment, in which the target is fetuses and not the adults, in addition to the conventional risk assessment At the same time, we also need a new strategy to practically eliminate the risk for the future generations. To make the strategy effective, we suggest a new approach to reduce the risk and avoid the possible adverse health effects, using primary, secondary and tertiary preventions as they are used in public health. We also suggest a new concept of "pre-primary prevention" to reduce the risk for fetuses. Furthermore, to make this method even more practical, we suggest a new risk communication method. In this paper, we present a framework of risk avoidance of multiple chemical exposure to fetuses. [source]

    Rule Breaking in New Product Development , Crime or Necessity?

    CREATIVITY AND INNOVATION MANAGEMENT, Issue 1 2001
    Tommy Olin
    The purpose of this study is to investigate the effect of applying general rules in organizations to govern multiple new product development projects. Data were collected in structured interviews with project managers and project members from seven successful projects within Swedish companies. Results show that projects either broke rules or that organizations had developed strategies to cope with the risk of rules preventing the progress of the projects. The project managers of the rule following projects reported lack of rule breaking to be the result of the rule design at each company, intending to minimize the risk of rules preventing the progress of projects. With the exception of the manager of the rule changing/removing project, project managers show a relaxed attitude to breaking general rules that hinder project progress. The study indicates that frameworks of common project management rules increase the risk of delay in new product development projects, unless strategies of rule breaking or dynamic rule modification are applied. Applications of emergent standard management philosophies and practices to innovation are discussed. [source]


    On Explaining Knowledge of Necessity

    DIALECTICA, Issue 1 2004
    Joel Pust
    Moderate rationalists maintain that our rational intuitions provide us with prima facie justification for believing various necessary propositions. Such a claim is often criticized on the grounds that our having reliable rational intuitions about domains in which the truths are necessary is inexplicable in some epistemically objectionable sense. In this paper, I defend moderate rationalism against such criticism. I argue that if the reliability of our rational intuitions is taken to be contingent, then there is no reason to think that our reliability is inexplicable. I also suggest that our reliability is, in fact, necessary, and that such necessary reliability neither admits of, nor requires, any explanation of the envisaged sort. [source]


    A posteriori Necessity in Singular Causation and the Humean Argument

    DIALECTICA, Issue 1 2003
    M.J. GARCÍA-ENCINAS
    The absence of a necessary connection in singular causation is a key step in the Humean argument against any form of necessity in causation. I argue that Hume's defence of this step is unsuccessful, and that the step could be skipped, accepting the possibility of necessary a posteriori truths. Still this does not suffice to guarantee a necessary connection in singular causation. Necessary a posteriori truths should be backed by necessary a priori truths. Thus, a main object of this paper is to argue that an a priori philosophical concept of causality involves a necessary connection between its terms. [source]


    Unilateral Intracarotid Amobarbital Procedure for Language Lateralization

    EPILEPSIA, Issue 11 2005
    Jörg Wellmer
    Summary:,Purpose: The determination of language dominance as part of the presurgical workup of patients with pharmacoresistant epilepsies has experienced fundamental changes. With the introduction of noninvasive functional magnetic resonance imaging (fMRI), the number of patients receiving intracarotid amobarbital procedures (IAPs) for assessment of language dominance has decreased considerably. However, recent studies show that because of methodologic limitations of fMRI, IAP remains an important tool for language lateralization. The current study examines whether unilateral instead of bilateral IAP is an adequate way to apply IAP with reduced invasiveness. Methods: We retrospectively examine the predictive value of unilateral IAP for the results of bilateral IAP based on a sample of 75 patients with various types of language dominance. Target parameters are the prediction of the language-dominant hemisphere and the identification of patients with atypical language dominance. For language assessment based on unilateral IAP, we introduce the measure hemispheric language capacity (HLC). Results: Unilateral IAP performed on the side of intended surgery quantifies language capacity contralateral to the intended surgery. It detects atypical (bilateral or right) language dominance in the majority of patients. Experience with a separate series of 107 patients requiring presurgical language lateralization shows that in >80%, bilateral IAPs are redundant. Conclusions: Unilateral IAP is principally sufficient for language lateralization in the presurgical evaluation of patients with pharmacoresistant epilepsies. Necessity of bilateral IAP is restricted to few indications (e.g., callosotomy). In times of noninvasive language lateralization, we propose unilateral IAP as the method of choice for the verification of doubtful (bilateral) fMRI activation patterns. [source]

    Projection and Necessity in Hume

    EUROPEAN JOURNAL OF PHILOSOPHY, Issue 1 2001
    P. J. E. Kail
    This paper discusses the metaphor of projection in relation to Hume's treatment of causal necessity. I argue that the best understanding of projection shows it to be compatible with taking Hume to be a ,sceptical realist' about causal necessity, albeit an agnostic one. [source]


    Necessity of re-evaluation of estramustine phosphate sodium (EMP) as a treatment option for first-line monotherapy in advanced prostate cancer

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 2 2001
    Tadaichi Kitamura
    Abstract Estramustine phosphate sodium (EMP) was first introduced in the early 1970s for the treatment of prostate cancer, when EMP was supposed to have the dual effect of estrogenic activity and cytotoxicity. For the following decades, it was used mainly in hormone-refractory cases, with a conventional dosage of 4,9 capsules/day, which showed a 30,35% objective response rate. However, a very limited number of cases have been reported that used EMP as a first-line monotherapy in the conventional dosage. One study showed a response rate of 82%, which is at least as effective as conventional estrogen (diethylstilbestrol; DES) monotherapy. Nevertheless, EMP was almost abandoned for the treatment of prostate cancer because of severe adverse side-effects, especially in the cardiovascular system and gastrointestinal tract. Recently, two facts have become evident. First, EMP interferes with cellular microtubule dynamics but does not show alkylating effects. Second, EMP is able to produce a complex with calcium when dairy products are taken concomitantly with EMP, resulting in a decrease in the absorption rate of EMP from the gut. Many clinical trials have been undertaken without warning against concomitant dairy product intake since the introduction of EMP. This fact will jeopardize almost all the clinical trials performed before 1990. It is considered that response rates have been underestimated and better results could have been obtained because side-effects decrease dose-dependently. Low-dose EMP monotherapy (2 capsules/day) has been performed infrequently in previously untreated advanced prostate cancer. The only large trial by the European Organization for Research and Treatment of Cancer in 1984 was biased in selecting patients. Nevertheless, the response rate of EMP is comparable to that of DES. In this study, the adverse side-effects of EMP were less than that of DES. Recently, a study was conducted at the University of Tokyo of 11 patients with advanced prostate cancer on low-dose EMP as first-line monotherapy. The study found that the mean serum prostate-specific antigen level decreased to within the normal range by day 50; mean serum testosterone, leutinizing hormone and follicle-stimulating hormone reduced to undetectable levels by day 20; and mean serum estradiol increased to a very high level within 1 week. These data implicate that low-dose EMP can suppress quickly and adequately the pituitary,gonadal axis, although the antitumor effect has not as yet been elucidated. For these reasons, it is necessary to re-evaluate low-dose EMP monotherapy in previously untreated advanced prostate cancer. [source]


    An investigation of medication adherence to 5-aminosalicylic acid therapy in patients with ulcerative colitis, using self-report and urinary drug excretion measurements

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 11-12 2009
    T. MOSHKOVSKA
    Summary Background, Non-adherence to 5-aminosalicylic acid (5-ASA) medication can limit the established benefits of this therapy in ulcerative colitis (UC). Aim, To determine rates and predictors of non-adherence to 5-ASA therapy in UC patients. Methods, Medication adherence was assessed using self-report data and urinary drug excretion measurements. Participants completed a study-specific questionnaire and two validated questionnaires: Beliefs about Medicine Questionnaire (BMQ)-Specific and Satisfaction with Information about Medicines Scale. Results, A total of 169 participants provided self-report adherence data; 151 also provided urine samples. Adherence rates were 111/151 (68%) according to self-report and 90/151 (60%) according to urine analysis, but the two measures were not correlated (,2 = 0.12, P = 0.725). Logistic regression identified a significant association between self-reported non-adherence and younger age [odds ratio (OR) for increased age 0.954, 95% confidence interval (CI) 0.932,0.976] and also doubts about personal need for medication (OR for BMQ , Specific Necessity scores 0.578, 95% CI 0.366,0.913). For non-adherence based on urine analysis, only South Asian ethnicity was independently associated with non-adherence (OR 2.940, 95% CI 1.303,6.638). Conclusions, Our observations confirm the difficulty of accurately assessing medication adherence. Nonmodifiable (younger age, South Asian ethnicity) and potentially modifiable (medication beliefs) predictors of non-adherence were identified. [source]

    Defibrillation Threshold Testing: Tradition or Necessity?

    PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 5 2009
    CHRISTOF KOLB M.D.
    Implantable cardioverter defibrillators (ICDs) have become an essential tool for primary and secondary prevention of sudden cardiac death. Traditionally, defibrillation threshold (DFT) testing is part of the "lege artis" ICD implantation. Taking into consideration that the absolute mortality reduction in primary prevention trials is estimated around 8% and in secondary prevention trials around 7%, it is only in these patients that an acceptable DFT is expected to affect survival. Using a high-energy ICD, the likelihood of obtaining an inadequate DFT is about 2.5%. Thus, the number of patients needed to be subjected to DFT testing in order to avert one potential death is about 500. Application of antitachycardia pacing for rapid ventricular tachycardias further reduces the percentage of patients dependent on reliable ICD defibrillation capability. Thus, the mortality rate that can be prevented by DFT testing is below 0.2%. This contrasts a 0.4% risk of life-threatening complications and a low but not negligible mortality risk owed to the procedure. Although in light of these data the balance between DFT-related risk and benefit seems to tilt toward the former, insights gained from prospective randomized trials will clarify whether the abandonment of routine DFT testing can be claimed on a rightful basis.

    Wittgenstein on The Standard Metre

    PHILOSOPHICAL INVESTIGATIONS, Issue 2 2004
    W. J. Pollock
    In this paper I argue that Wittgenstein is correct when he says of the Standard Metre stick that we can neither say that it is or is not a metre in length , despite what our intuitions may tell us to the contrary. Specifically, the paper deals with Kripke's criticism of Wittgenstein's claim in Naming And Necessity and with Salmon's attempt to arbitrate between the two views. I conclude that, not only is Wittgenstein correct, but that both Kripke and Salmon (and possibly the majority of philosophers) simply do not understand the concept of measurement. [source]


    A NOTE ON KRIPKE's FOOTNOTE 56 ARGUMENT FOR THE ESSENTIALITY OF ORIGIN

    RATIO, Issue 3 2005
    Ross P. Cameron
    In footnote 56 of his Naming and Necessity, Kripke offers a ,proof' of the essentiality of origin. On its most literal reading the argument is clearly flawed, as was made clear by Nathan Salmon. Salmon attempts to save the literal reading of the argument, but I argue that the new argument is flawed as well, and that it can't be what Kripke intended. I offer an alternative reconstruction of Kripke's argument, but I show that this suffers from a more subtle fault. [source]

    Treating acute mental illness in rural general hospitals: Necessity or choice?

    AUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 4 2006
    Catherine Hungerford
    Abstract Objective:,To identify reasons why rural general practitioners (GPs) treat a large proportion of patients with a primary psychiatric diagnosis in general beds of their local hospitals, and the barriers encountered when providing this treatment. Design:,A postal questionnaire was developed and distributed to a sample of rural GPs, asking about the treatment of patients with an acute mental illness in their local hospital. Results:,The majority of GPs agreed that they treat the acutely mentally ill in general beds of their local hospital due to lack of availability of, and inability to gain access to, mental health beds in the larger centres; and also to enable ongoing family involvement and continuity of care. Distance factors were identified as least significant. Barriers to providing care to this group of patients included a perceived lack of support by consultant psychiatrists, confidentiality issues, lack of community mental health workers to provide assistance, aggression levels of patients, inappropriate local hospital setting, and lack of confidence of GPs and general hospital nursing staff. Conclusion:,Addressing these barriers is necessary if rural Australians are to receive a quality of care that is equal to that received by those located in metropolitan Australia. Continuing research in this area is crucial. [source]


    MEASURING POVERTY , WHAT HAPPENED TO COPENHAGEN?

    ECONOMIC AFFAIRS, Issue 3 2007
    Chris Sarlo
    Absolute poverty can be thought of as a condition of ,insufficiency', i.e. the inability to acquire the basic necessities of life. Relative poverty can be thought of as a condition of ,inequality'. At the World Summit on Social Development in Copenhagen in 1995, all participants made a commitment to produce official measures of both absolute and relative poverty and to strive to eradicate absolute poverty within a reasonable time frame. Despite these commitments, measures of absolute poverty are rare in the developed world. This paper concludes that both kinds of measures are needed for intelligent discussions and good policy-making. [source]


    The perspectives of energy production from coal-fired power plants in an enlarged EU

    INTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 9 2004
    P. Grammelis
    Abstract The aim of this paper is to present the current status of the coal-fired power sector in an enlarged EU (EU-15 plus EU member candidate states) in relation with the main topics of the European Strategy for the energy production and supply. It is estimated that 731 thermoelectric units, larger than 100 MWe, are operating nowadays, and their total installed capacity equals to 200.7 GWe. Coal contribution to the total electricity generation with reference to other fuel sources, is by far more intensive in the non-EU part (EU member candidate states), compared to the EU member states. It is expected that even after the enlargement, the European Union will strongly being related to coal. Enlargement will bring additional factors into play in order to meet the requirements of rising consumption, growing demand for conventional fuels and increasing dependence on imports. Besides the technology, boiler size, efficiency, age and environmental performance will determine the necessities of the coal-fired power sector in each country. Depending on the case, lifetime extension measures in operating coal-fired power plants or clean coal technologies can play an important role towards the energy sector restructuring. Low efficiency values in the non-EU coal-fired units and heavily aged power plants in EU countries will certainly affect decisions in favour of upgrading or reconstruction. The overall increase of efficiency, the reduction of harmful emissions from generating processes and the co-combustion of coal with biomass and wastes for generating purposes indicate that coal can be cleaner and more efficient. Additionally, plenty of rehabilitation projects based on CCT applications, have already been carried out or are under progress in the EU energy sector. The proclamations of the countries' energy policies in the coming decades, includes integrated renovation concepts of the coal-fired power sector. Further to the natural gas penetration in the electricity generation and CO2 sequestration and underground storage, the implementation of CCT projects will strongly contribute to the reduction of CO2 emissions in the European Union, according to the targets set in the Kyoto protocol. In consequence, clean coal technologies can open up new markets not only in the EU member candidate states, but also in other parts of the world. Copyright © 2004 John Wiley & Sons, Ltd. [source]


    Victims of Domestic Violence: A Proposal for a Community Diagnosis Based on One of Two Domains of NANDA Taxonomy II

    INTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 2003
    Patricia Serpa de Souza Batista
    PURPOSE To explore and identify diagnostic components to amplify NANDA nursing diagnoses by modifying the root violence. Whereas violence is nondebatable as a diagnostic concept in nursing, other alternatives have not been identified in the two existing diagnoses. METHODS Using the case study method, this qualitative study sought to identify commonalties in a population of women who were "donnas da casa" (homemakers) in a small rural community of approximately 100 families, typical of the Brazilian northeast. The sample of 7 women was identified through a larger study that had been based on health needs of the community. Data were obtained through observation during a home visit and a semistructured interview based on NANDA Taxonomy II. Observations were focused on hygiene, manner of dress, home environment, and physical and emotional state. Data were analyzed by content and clustered into major categories. From these a profile of the women and another of the partners emerged. FINDINGS Subjects ranged in age from 33 to 43 years, and number of children between 3 and 7. One of the 7 women was literate; 5 were underweight; all were slovenly attired. They appeared sad and older than their age. The majority seemed relieved to unburden themselves to the interviewers as they went through a gamut of emotions such as sadness, anguish, and irritability expressed through crying, restlessness, changes in body language, and tone of voice. The shortage of beds was supplemented by hammocks and mats or cardboard. The women spoke of being confined to their home and of male partners who drank on weekends, thus leaving them with little money for necessities of life. There were accounts of beatings when the partner returned home after drinking, overt nonacceptance of children from previous marriages, and general destruction of the family environment. New children were regarded as just another mouth to feed. DISCUSSION The profiles pointed to the necessity of identifying a new nursing diagnosis that would be linked, only tangentially, by the root violence to the two diagnoses in NANDA Taxonomies I and II. This insight led us to consider that a new method of listing NANDA diagnoses, by root only, is imperative in the evolution of Taxonomy II. Proposed descriptors, Victims of (Axis 3) and Domestic (Axis 6) would be identified by Axes, thereby facilitating the process of classifying in the Domains and Classes. The two existing NANDA diagnoses, risk for other-directed violence and risk for self-directed violence, are proposed for classification in Class 3, Violence, in Domain 11 of Taxonomy II. Safety/Protection could, by virtue of their modification power, find anchor in another domain such as Domain 6, Self-Perception. CONCLUSIONS Although Safety/Protection seems the most logical domain for classification by root, the axes, dimensions of human responses, could pull the diagnosis in another direction, thereby dictating other nursing interventions and nursing outcomes [source]


    Giving to Organizations that Help People in Need: Differences Across Denominational Identities

    JOURNAL FOR THE SCIENTIFIC STUDY OF RELIGION, Issue 3 2010
    Mark Ottoni-Wilhelm
    This article uses multiple-year data to examine charitable giving to organizations that help people in need of food, shelter, or other basic necessities. Families that give to basic necessity organizations in any single year are a mix of occasional givers and regular givers. Controlling for family characteristics that affect giving, giving to basic necessity organizations does not vary across Christian denominations and nonaffiliated families in any notable way. However, Jewish families are both more likely to give and, when they do give, give larger amounts. Given recent policy interest in how churches, synagogues, and mosques help with the voluntary provision of a safety net for people in need, the results draw attention to the importance of a research agenda focused on the differences between occasional givers and regular givers and on explaining why Jewish families give more to organizations that help people in need.

    An error corrected almost ideal demand system for major cereals in Kenya

    AGRICULTURAL ECONOMICS, Issue 1 2010
    Jonathan M. Nzuma
    Error correction model; AIDS; Cereal consumption; Kenya Abstract Despite significant progress in theory and empirical methods, the analysis of food consumption patterns in developing countries, particularly those in Sub-Saharan Africa (SSA), has received very limited attention. An attempt is made in this article to estimate an Error Corrected Almost Ideal Demand System for four major cereals consumed in Kenya employing annual data from 1963 to 2005. This demand system performs well on both theoretical and empirical grounds. The symmetry and homogeneity conditions are supported by the data and the,Le Chatelier,principle holds. Empirically, all own-price elasticities are negative and significant at 5% level and irrespective of the time horizon, maize, wheat, rice, and sorghum may be considered as necessities in Kenya. While the expenditure elasticities of all four cereals are positive, they are inelastic both in the short run and in the long run. Finally, wheat and rice complement maize consumption in Kenya while sorghum acts as a substitute. Since cereal consumers have price and income inelastic responses, a combination of income and price-oriented policies could improve cereal consumption in Kenya. [source]


    An error correction almost ideal demand system for meat in Greece

    AGRICULTURAL ECONOMICS, Issue 1 2000
    G. Karagiannis
    Abstract This paper represents a dynamic specification of the Almost Ideal Demand System (AIDS) based on recent developments on cointegration techniques and error correction models. Based on Greek meat consumption data over the period 1958,1993, it was found that the proposed formulation performs well on both theoretical and statistical grounds, as the theoretical properties of homogeneity and symmetry are supported by the data and the LeChatelier principle holds. Regardless of the time horizon, beef and chicken may be considered as luxuries while mutton-lamb and pork as necessities. In the short-run, beef was found to have price elastic demand, pork an almost unitary elasticity, whereas mutton-lamb, chicken and sausages had inelastic demands; in the long-run, beef, and pork were found to have a demand elasticity greater than one, whereas mutton-lamb, chicken, and sausages still had inelastic demands. All meat items are found to be substitutes to each other except chicken and mutton-lamb, and pork and chicken. [source]


    Learning the Dynamic Processes of Color and Light in Interior Design

    JOURNAL OF INTERIOR DESIGN, Issue 2 2009
    Tiiu Poldma Ph.D.
    ABSTRACT Interior environments and their design are profoundly influenced by how designers integrate color and light with form and space. In our increasingly global world, new lighting technologies are changing our perception of color and light and subsequently our interrelationships with one another and with interior space. This alters the choices that we have as designers when we make both color and light decisions. Traditional light and color theories are being challenged with new lighting approaches that are complex, dynamic, and that are changing people's immediate experiences within spaces. Currently, new light technologies alter our perceptual relationships with people and forms, as light, its spectral color, and the forms its affects are more interactive and modulated in real time. Usually, in interior design coursework, students learn about color and light as static theories that they are then asked to apply within the interior design of spaces in subsequent design studios. Through a presentation and examination of the course "Color and Light in Interior Design," this paper proposes considering integrating color and light theories with new contexts of dynamic, integrated human experiences of color and light in interior space. Students acquire learning experiences that integrate theory and practice by understanding the complex interrelationships of light, color, and objects in interior spaces as interactive, and by exploring design concepts in actual environments as a laboratory where they can test theories and their own ideas. The course structure is described and the theories underlying the course goals are explored. Color and light theories are considered in the context of emerging technologies and how phenomenological approaches affect our perceptions and experiences in spaces. Student examples of two of the four course projects are presented as these put theories into practice. The discussion shows that light and color theory, when explored in this way, stimulates both comprehensive and creative responses that integrate new technology with aesthetic theory and functional aspects of well-designed light/color solutions. The integrating of practice into theory stimulates reflective thinking and an understanding of situated contexts in interior design problem solving. The course develops emerging necessities of understanding dynamic color/light concepts that contribute to broadening interior design applied knowledge. [source]


    The U.S. Policy and Strategy toward DPRK: Comparison and Evalution of the Clinton and Bush Administrations

    PACIFIC FOCUS, Issue 2 2002
    Hun Kyung Lee
    This article focuses on studying and evaluating the Clinton and Bush administrations' policies and strategies toward North Korea. The Clinton administration's policy toward North Korea was a continuation of the abandonment of containment and confrontation strategies of the Cold War era. That policy was based on a strategic transfer of power for the purpose of preventing a war, through a combination of aid and deterrence in the Korean peninsula by its engagement policy. The Administration believed that additional food aid and easing of economic sanctions would make a contribution to North Korean survival, and hence, a reduction in its bellicose disposition. Providing that this policy continued, it would be possible not merely to lead North Korea's change, but also to help it enter into international society by breaking down its self-imposed isolation. To the contrary, the Bush administration points out that the Clinton administration's engagement policy did not lead to North Korea's change, and even left the wrong precedent in nuclear and missile negotiations. Focusing on nonproliferation of weapons of mass destruction with an emphasis of transparency, monitoring, and verification, the Bush administration has claimed a broad agenda. This includes an improved implementation of the Agreed Framework relating to North Korea's nuclear activities, verifiable control over North Korea's missile programs and a ban on its missile exports, and a less threatening conventional military posture. With the different views of these two administrations as a background, this article explores the U.S. efforts for achieving such policy goals as freezing North Korea's nuclear weapons program and halting its missile development and sales, together with looking at North Korea's response. American efforts for supporting the necessities for life, easing of some economic sanctions toward DPRK are also described. At the same time, the U.S. policy toward DPRK is evaluated on the whole in considering U.S. policy limits for nonproliferation of weapons of mass destruction, the lack of effort by North Korea for peacemaking and survival, and inconsistency on U.S. assistance. Lastly, this article suggests a way for an alternative solution by thinking about some dilemmas for the U.S. and the DPRK. [source]
