Tunneling oscillations induced in a double quantum well by a monochromatic electromagnetic wave incident perpendicularly to the plane of the well, and polarized along the direction of its growth, are treated. For the wave frequency in proximity to the energy difference between two states of opposite symmetry, a periodic energy exchange between the wave and a carrier which moves from one energy state to the other is established. When the carrier starts from the low energy level it borrows energy from (...) the wave until it reaches the higher energy state. On its way the carrier performs current oscillations that cease whenever it reaches an eigenstate. Similarly, oscillation is required during the carrier's motion from the high to the low energy state for the photon emission in order that the radiation gets back the energy already given to the carrier. Thus an accelerating charge not only radiates, but also absorbs wave energy. When there prevails a considerable population difference between the two levels the possibility of quantum beat exits.

Bu çalışma Osmanlı Devleti’nin Kıbrıs Adası’nı fethi ile özgürlüğünü yeniden kazanmış olan Kıbrıs Rum Ortodoks Kilisesi’nin, İngiliz idaresi döneminde yaşamış olduğu iki siyasi kilise krizini konu etmektedir. İngilizlerin Kıbrıs’ta idaresi iki döneme ayrılmaktadır. Birincisi 1878 yılında Osmanlı Devleti ile yapılan iki maddelik antlaşma kapsamında 1914 yılına kadar devam eden ve adanın fiilen Osmanlı toprağı olarak kabul edildiği dönem; ikincisi ise 1914 yılında İngiltere’nin adayı tek taraflı ilhakından 1960 yılında Kıbrıs Cumhuriyeti’nin kurulmasına kadar olan dönemdir. İngiliz idaresi döneminde gerçekleşmiş olan kilise (...) krizlerinin ilki 1900-1910 yılları arasında Kitium Piskoposu Kyrillos Papadopoulos ile Girne Piskoposu Kyrillos Basileiou arasında gerçekleşmiştir. İkincisi ise 1933-1947 yılları arasında Baf Metropoliti Leontios Leontiou’nun 1931 isyanları sebebiyle ada dışında sürgünde olan metropolitlerin adaya dönmeden seçim yapılamayacağını beyan etmesi sebebiyle gerçekleşmiştir. Kıbrıs Rum Ortodoks Kilisesi otosefal bir kilise olması sebebiyle iç işlerine diğer kiliseleri karıştırmak istememiş, ancak çıkmaza giren piskoposluk seçimi nedeniyle müdahale kaçınılmaz olmuştur. Bugüne kadar siyasetteki etkisi var olagelen Kıbrıs Rum Ortodoks Kilisesi, 20. Yüzyılın henüz başında geçirmiş olduğu kilise krizlerini ancak siyasetin etkisi ve yardımıyla aşabilmiştir. Kıbrıs’ta ilk Yunan bayrağı birinci kilise krizi döneminde bir taraftar toplama çalışması olarak II. Kyrillos (Kyrillos Papadopoulos) tarafından Trooditissa Manastırı’na çekilmiştir. Ancak Kıbrıs Adası’nın ne daha önceki dönemlerde ne de şimdi Yunanistan ile hiçbir bağı yoktur. Kıbrıs Adası’nda yaşayan Rumlar ile Yunanistan arasında bir bağ oluşturmaya çalışan ve bunu iddia eden de yine kilisedir. Kıbrıs Cumhuriyeti birinci Cumhurbaşkanı III. Makarios’un başpiskopos seçilmesine giden süreçte bahsedilen iki kilise krizi büyük önem taşımaktadır. Bu dönemde başpiskopos adayları arasında, rakip adaya karşı Enosis’i ateşli bir şekilde savunmamak, İngiliz idaresine fazla yakın olmak gibi suçlamalar olmuştur. III. Makarios hem ateşli bir şekilde Enosis’i savunmuş, hem de İngiliz idaresi ile her zaman çatışma halinde olmuştur. Bu süreç ona önce başpiskoposluk, sonrasında ise Kıbrıs Cumhuriyeti Cumhurbaşkanlığı getirmiştir. Kıbrıs’ta zikri geçen dönemde özellikle ön plana çıkan Türk düşmanlığı, başpiskopos olmanın ilk şartı sayılmıştır. Şöyleki; İngilizler adayı tek taraflı ilhak ettikten sonra İngilizlerin adayı kendilerine bırakacağına neredeyse emin olan Rum Ortodoks Kilisesi başpiskoposları, önce İngiliz idaresi düşmanlığı, sonra Türk düşmanlığı üzerinden kilise propagandası yapmışlardır. Çalışmada otosefal bir kilise olan Kıbrıs Rum Ortodoks Kilisesi’nin, kilise içi anlaşmazlıklardaki tavrı ile kilise kurallarına bağlılığı da ele alınmaktadır. Enosis düşüncesinin piskoposluk seçimine etkisinin daha net görüleceği bu iki kriz, kilisenin bugününü anlamak açısından oldukça önemlidir. (shrink)

This article aims to explicate the concept of emotional sharing against the background of interactive and situated approaches to affectivity, and to contextualize emotional sharing within the broader context of emotion research. It brings together research on situated affectivity with the debate on collective emotion. Emotional sharing is defined via four requirements and distinguished from other phenomena in the broad field of collective emotion, especially from mechanisms of emotional convergence and other forms of affective we-experience. The paper makes use of (...) the recently proposed concepts of affective scaffolding and affective arrangement to explore how emotional sharing is always enacted in sociorelational dynamics and embedded in socio-material contexts which enable, shape, and modulate the unfolding of emotional sharing and regulate who is likely to participate.

This article presents evidence supporting the claim that ethical reasoning is a skill that can be taught and assessed. We propose a working definition of ethical reasoning as 1) the ability to identify, analyze, and weigh moral aspects of a particular situation, and 2) to make decisions that are informed and warranted by the moral investigation. The evidence consists of a description of an ethical reasoning education program—Ethical Reasoning in Action —designed to increase ethical reasoning skills in a variety of (...) situations and areas of life. ERiA is housed at a public, major comprehensive U.S. university—James Madison University—and assessment of the program focuses on interventions delivered prior to and during orientation for incoming first-year students. Findings indicate that the interventions measurably enhance the ability of undergraduate students to reason ethically. ERiA’s competency-targeted program and positive student learning outcomes offers a promising model for higher education ethics programs seeking to connect classroom learning in ethics to decision-making in everyday life.

Now in its fourth edition, Rational Diagnosis and Treatment: Evidence-Based Clinical Decision - Making is a unique book to look at evidence-based medicine and the difficulty of applying evidence from group studies to individual patients._ The book analyses the successive stages of the decision process and deals with topics such as the examination of the patient,_the reliability of clinical data, the logic of diagnosis, the fallacies of uncontrolled therapeutic experience and the need for randomised clinical trials and meta-analyses. It is (...) the main theme of the book that, whenever possible, clinical decisions must be based on the evidence from clinical research, but the authors also explain the pitfalls of such research and the problems involved in applying evidence from groups of patients to the individual patient._ For this new edition, the sections on placebo and meta-analysis and on alternative medicine have been thoroughly updated, and there is more focus on insufficient reporting of harms of interventions. The sections on different research designs describe advantages and limitations, and the increased medicalisation and the effects of cancer screening on health people are noted. A section on academic freedom when clinicians collaborate with industry and ghost authors is added._ This essential reference work integrates the science and statistical approach of evidence-based medicine with the art and humanism of medical practice; distinguishing between data, sets of data, knowledge and wisdom, and their application. Such an intellectually challenging book is ideal for both medical students and doctors who require theoretical and practical clinical skills to help ensure that they apply theory in practice.

The complex chaotic dynamics and multistability of financial system are some important problems in micro- and macroeconomic fields. In this paper, we study the influence of two-delay feedback on the nonlinear dynamics behavior of financial system, considering the linear stability of equilibrium point under the condition of single delay and two delays. The system undergoes Hopf bifurcation near the equilibrium point. The stability and bifurcation directions of Hopf bifurcation are studied by using the normal form method and central manifold theory. (...) The theoretical results are verified by numerical simulation. Furthermore, one feature of the proposed financial chaotic system is that its multistability depends extremely on the memristor initial condition and the system parameters. It is shown that the nonlinear dynamics of financial chaotic system can be significantly changed by changing the values of time delays. (shrink)

Foucault’s remarks concerning psychoanalysis are ambivalent and even prima facie contra-dictory, at times lauding Freud and Lacan as anti-humanists, at others being severely criti-cal of their imbrication within psychiatric power. This has allowed a profusion of interpretations of his position, between so-called ‘Freudo-Foucauldians’ at one extreme and Foucauldians who condemn psychoanalysis as such at the other. In this article, I begin by surveying Foucault’s biographical and theoretical relationship to psychoanalysis and the sec-ondary scholarship on this relationship to date. I pay (...) particular attention to the discussion of the relationship in feminist scholarship and queer theory, and that by psychoanalytic thinkers, as well as attending to the particular focus in the secondary literature on Fou-cault’s late work and his relationship to the figure of Jacques Lacan. I conclude that Fou-cault’s attitude to psychoanalysis varies with context, and that some of his criticisms of psychoanalysis in part reflect an ignorance of the variety of psychoanalytic thought, partic-ularly in its Lacanian form. I thus argue that Foucault sometimes tended to overestimate the extent of the incompatibility of his approach with psychoanalytic ones and that there is ultimately no serious incompatibility there. Rather, psychoanalysis represents a substantively different mode of inquiry to Foucault’s work, which is neither straightforwardly ex-clusive nor inclusive of psychoanalytic insights. (shrink)

The aim of this article is to offer what I consider to be necessary substantiati for the view that the description of the walk which acts as a frame for the singing contest in Id. 7 is based on a precise knowledge of the geography of t island of Cos and that the poem thus displays a topographical realism unique Greek pastoral.

At the end of the prayer with which he begins Works of Love (1847), Søren Kierkegaard notes that while ‘works of love’ might normally be viewed as a subset of worthwhile human endeavours or ‘works’, from heaven's perspective no work can be pleasing unless it is a work of love. From this arises the question—which Kierkegaard himself moves swiftly to address—of what distinguishes a work of ‘love’ from other, non-loving works? In this article, and with particular reference to Jacob Boehme (...) (1575–1624), I highlight how Kierkegaard's answer to this question draws upon the theological tradition that Bernard McGinn has called ‘the mysticism of the ground’. (shrink)

Contemporary medical education must train skilled and compassionate health care professionals who are rigorous in their approach to patient care and their pursuit of knowledge and solutions. Problem-based learning has been widely introduced, but there is no evidence that it leads to better outcomes than more traditional programs, and fundamental gaps in conceptual knowledge may result. Recently, emphasis has been placed on a solid grounding in underlying concepts combined with a systems-based approach, and ability to transfer information and solve problems. (...) Integrating traditional scientific and clinical disciplines with progressive and continuous assessment, may be a better means of achieving the combined aims of clinically relevant curriculum design, vertical integration of medical knowledge, and facilitation of the continuum of training. Being adaptable and flexible, cognisant of costs, and driven by evidence are key features of delivering medical education and contemporary medical practice. Educational research should lead to continuous improvement, but innovation without evaluation and attention to costs may create as many, or more, problems as are solved. (shrink)
