An examination of our preconceptions about desire, together with a comparison of these with the available empirical evidence, leads to a theory in which desire is characterized as a cognitive phenomenon which is heavily influenced by social learning. Following an introductory outline, the second section clarifies what exactly is at issue in attempting to reduce conation to cognition. Section 3 assesses the conditions required for knowledge of our own desires, and this concern is extended in 4 to an appraisal of (...) the role played by self-knowledge in the process of change through psychotherapy. The concluding section argues that the Social-cognitive Theory of Desire is compatible with contemporary neo-Dar-winian views of evolution. (shrink)

Oral healthcare is attracting much attention after decades of neglect from policymakers. Recent studies have shown a strong association between oral and overall health, which can lead to serious health problems. Availability of oral healthcare services is an essential part of ensuring universal healthcare coverage. More importantly, current gaps in its accessibility by minority or marginalized population groups are crucial public health as well as ethical concerns. One notable effort to address this issue comes from Non-Governmental Organizations (NGOs), which offer (...) oral healthcare services for non-insured refugees. However, the challenge remains that these care services are not comprehensive, which has implications for the refugees’ oral and general health. In this article, we discuss this complex issue in the German healthcare context by including ethical reflections. Therefore, the purpose of this article is to discuss the ethical challenges related to oral healthcare services provided by NGOs for refugees in Germany. First, we will introduce the general oral healthcare context worldwide and in Germany. Second, we will provide a general description of the oral healthcare services provided by NGOs for refugees in Germany, as well as an overview of existing gaps. This will provide us with the context for our third and most important task—discussing the ethical implications of the gaps. In doing so, and since the ethical implications can be several, we demarcate the scope of our analysis by focusing on the specific ethical issues of justice, harm, and autonomy. Finally, we offer some recommendations for how to move forward. (shrink)

K.J. Devlin has extended Jensen's construction of a model ofZFC andCH without Souslin trees to a model without Kurepa trees either. We modify the construction again to obtain a model with these properties, but in addition, without Kurepa trees inccc-generic extensions. We use a partially defined ◊-sequence, given by a fine structure lemma. We also show that the usual collapse ofκ Mahlo toω 2 will give a model without Kurepa trees not only in the model itself, but also inccc-extensions.

Background: Although fair distribution of healthcare services for older patients is an important challenge, qualitative research exploring clinicians’ considerations in clinical prioritisation within this field is scarce. Objectives: To explore how clinicians understand their professional role in clinical prioritisations in healthcare services for old patients. Design: A semi-structured interview-guide was employed to interview 45 clinicians working with older patients. The interviews were analysed qualitatively using hermeneutical content analysis. Participants: 20 physicians and 25 nurses working in public hospitals and nursing homes (...) in different parts of Norway. Results and interpretations: The clinicians struggle with not being able to attend to the comprehensive needs of older patients, and being unfaithful to professional ideals and expectations. There is a tendency towards lowering the standards and narrowing the role of the clinician. This is done in order to secure the vital needs of the patient, but is at the expense of good practice and holistic role modelling. Increased specialisation, advances and increase in medical interventions, economical incentives, organisational structures, and biomedical paradigms, may all contribute to a narrowing of the clinicians’ role. Conclusion: Distributing healthcare services in a fair way is generally not described as integral to the clinicians’ role in clinical prioritisations. If considerations of justice are not included in clinicians’ role, it is likely that others will shape major parts of their roles and responsibilities in clinical prioritisations. Fair distribution of healthcare services for older patients is possible only if clinicians accept responsibility in these questions. (shrink)

The discrete-time system has more complex and chaotic dynamical behaviors as compared to the continuous-time system. This paper extends a discrete Leslie–Gower predator-prey system with the Allee effect in the predator’s population, whose dynamics are analyzed and explored. We have determined the equilibrium points and studied their local stability properties. We find that the system undergoes flip bifurcation and Neimark–Sacker bifurcation around the interior equilibrium point by choosing the Allee parameter as a bifurcation parameter. We discuss the stability and direction (...) of both bifurcations with the help of the normal form theory and center manifold theorem. The flip bifurcation and Neimark–Sacker bifurcation are the most common routes to the chaotic orbit in the discrete system. Moreover, we utilize state feedback, pole placement, and hybrid control methods to control the chaos in the system. The work is complete with the numerical simulations to confirm the analytical findings. (shrink)

Ecology is being introduced to Evolutionary Developmental Biology to enhance organism-, population-, species-, and higher-taxon-level studies. This exciting, bourgeoning troika will revolutionise how investigators consider relationships among environment, ontogeny, and phylogeny. Features are studied (and even defined) differently in ecology, development, and evolution. Form is central to development and evolution but peripheral to ecology. Congruence (i.e., homology) is applied at different hierarchical levels in the three disciplines. Function is central to ecology but peripheral to development. Herein, the supercategories form (‘isomorphic’ (...) or ‘allomorphic’), congruence (‘homologous’ or ‘homoplastic’), and function (‘adaptive’ or ‘nonadaptive’) are combined with two developmental mode (i.e., growth) categories (‘conformational’ or ‘nonconformational’) to provide a 16-class system for analysing features in studies in which ecology, development, and evolution are integrated.

Alzheimer's disease is characterized by amyloid-beta peptide -loaded plaques in the brain. Abeta is a cleavage fragment of amyloid-beta protein precursor and over production of APP may lead to amyloidogenesis. The regulatory region of the APP gene contains consensus sites recognized by the transcription factor, specificity protein 1 , which has been shown to be required for the regulation of APP and Abeta. To understand the role of SP1 in APP biogenesis, herein we have characterized the relative distribution and localization (...) of SP1, APP, and Abeta in various brain regions of rodent and primate models using immunohistochemistry. We observed that overall distribution and cellular localization of SP1, APP, and Abeta are similar and neuronal in origin. Their distribution is abundant in various layers of neocortex, but restricted to the Purkinje cell layer of the cerebellum, and the pyramidal cell layer of hippocampus. These findings suggest that overproduction of Abeta in vivo may be associated with transcriptional pathways involving SP1 and the APP gene. (shrink)

Supersaturated hcp f -Zr alloys containing 22-28 at.% N were prepared by nitriding sheets of Zr in an atmosphere of high-purity N 2 , followed by homogenization under high-purity Ar gas. Quenching and isothermal ageing of the alloys for various times between 500 and 650°C resulted in precipitation of a metastable phase, rather than the equilibrium phase ZrN. This investigation focused on determining the structure, orientation relationship, habit plane, morphology, growth kinetics and atomic growth mechanism of this non-equilibrium precipitate using (...) transmission electron microscopy imaging and diffraction techniques, high-resolution transmission electron microscopy, electron-energy-loss spectroscopy and various simulation programs. The precipitate, which was arbitrarily designated the  phase, has a monoclinic Bravais lattice. Its lattice parameters are a = 0.32 nm, b = 0.60 nm, c = 0.56 nm, f = g = 90° and n = 121.5°. Its orientation relationship with the f matrix is $$ _alpha /mskip-2/ _xiquad adquad [01bar 10] _alpha /mskip-2/ [001]_xi, $$ and the average habit plane of lenticularly shaped precipitates is $_alpha$ . Determination of the structure and other aspects of the phase transformation are discussed. (shrink)

William Frankena has several times discussed, in his usual cautious and judicious manner, a contrast between two types of normative ethics: an ethics of “duty” and an ethics of “virtue.” Without claiming that actual philosophers have been pure exemplars of either type, he has tried to give a clear statement of these two possible and contrasting types of theory, and to expose their problems. His final view seems to be that a complete normative theory will combine elements of both, but (...) that an ethics of “duty” in some sense is more fundamental. Plato and Aristotle seem to differ from him in being more sympathetic to a “virtue-ethics.” Leslie Stephen went so far as to claim that satisfactory principles of duty cannot even be stated and that a moral philosopher spends his time better formulating an ideal of virtue. James Martineau is another classical figure more sympathetic to “virtue-ethics.”. (shrink)

Background: Since the passage of the Patient Self-Determination Act, numerous policy mandates and institutional measures have been implemented. It is unknown to what extent those measures have affected end-of-life care, particularly with regard to the do-not-resuscitate order.Methods: Retrospective cohort study to assess associations of the frequency and timing of DNR orders with advance directive status, patient demographics, physician’s specialty and extent of documentation of discussion on end-of-life care.Results: DNR orders were more frequent for patients on a medical service than on (...) a surgical service and were made earlier in the hospital stay for medicine than for surgical patients . 22.18% of all patients had some form of an advance directive in their chart, yet this variable had no impact on the frequency or timing of DNR ordering. Documentation of DNR discussion was significantly associated with the frequency of DNR orders and the time from DNR to death .Conclusions: The physician’s specialty continues to have a significant impact on the frequency and timing of DNR orders, while advance directive status still has no measurable impact. Additionally, documentation of end-of-life discussions is significantly associated with varying DNR ordering rates and timing. (shrink)

The objectives of this study were to develop a high-density chromosome bin map of homoeologous group 7 in hexaploid wheat, to identify gene distribution in these chromosomes, and to perform comparative studies of wheat with rice and barley. We mapped 2148 loci from 919 EST clones onto group 7 chromosomes of wheat. In the majority of cases the numbers of loci were significantly lower in the centromeric regions and tended to increase in the distal regions. The level of duplicated loci (...) in this group was 24% with most of these loci being localized toward the distal regions. One hundred nineteen EST probes that hybridized to three fragments and mapped to the three group 7 chromosomes were designated landmark probes and were used to construct a consensus homoeologous group 7 map. An additional 49 probes that mapped to 7AS, 7DS, and the ancestral translocated segment involving 7BS also were designated landmarks. Landmark probe orders and comparative maps of wheat, rice, and barley were produced on the basis of corresponding rice BAC/PAC and genetic markers that mapped on chromosomes 6 and 8 of rice. Identification of landmark ESTs and development of consensus maps may provide a framework of conserved coding regions predating the evolution of wheat genomes. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

This anthology collects readings from important nineteenth and early twentieth century figures who contributed to the philosophy of science before that discipline emerged in the last 40 years as an area of study in its own right. It begins with a seldom-read selection by Kant ) and ends with a selection from Bridgman's The Logic of Modern Physics. Each selection is preceded by a three-page biography of the author together with a bibliography of his major writings and some writings on (...) his work. Many familiar names appear, e.g., Mill, Mach, Pearson, Hertz, Poincare, Peirce, Duhem, Russell, Whitehead, and Campbell. But there are others represented whose actual writings are not so familiar to many students of the philosophy of science, e.g., J. F. W. Herschel, William Whewell, Hermann Von Helmholtz, J. B. Stallo, Emile Boutroux and William Ostwald. With the exception of Stallo, the writings of these figures have been long out of print. In one case, a selection from Ludwig Boltzmann on the nature of mechanics, the editor has translated the selected passage into English expressly for this volume. A wide range of topics are considered in the readings: physical laws, theories, induction, observation, space, time, and others; but, as the nature of the case requires, the focus of attention is on classical science. For this reason most existing courses in the philosophy of science could use this collection only as a supplementary text. But it would function well in such a role. Moreover, specialized courses in the history of philosophical thinking about science will find it very useful.--R. H. K. (shrink)

In this article, we present results from a literature review of intrinsic, instrumental, and relational values of nature conducted for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, as part of the Methodological Assessment of the Diverse Values and Valuations of Nature. We identify the most frequently recurring meanings in the heterogeneous use of different value types and their association with worldviews and other key concepts. From frequent uses, we determine a core meaning for each value type, which is (...) sufficiently inclusive to serve as an umbrella over different understandings in the literature and specific enough to help highlight its difference from the other types of values. Finally, we discuss convergences, overlapping areas, and fuzzy boundaries between different value types to facilitate dialogue, reduce misunderstandings, and improve the methods for valuation of nature's contributions to people, including ecosystem services, to inform policy and direct future research. © 2023 The Author(s).

Since the beginning of human history, there has been no society that did not have any religion. Man meets his need to believe, encoded in his nature by turning to God. God has not left humans alone in their journey on earth, and from time to time, He has intervened in the world through his prophets. The prophethood, which constitutes one of the main subjects of theology, is an important institution in God-human communication. The messengers chosen by God convey to (...) people the information that they received through revelation and offer teachings that will bring them to salvation. The idea of salvation by God when suffering or feeling helpless has driven people to the expectation of a savior. Nearly all religions except Shintoism have the awaited savior belief in the world. Accordingly, the savior will emerge in an environment of chaos where disasters are experienced, and a moral collapse is observed. The expected savior will drive people away from this turmoil, bring them happiness, well-being, and lead them to salvation. Although there is a savior belief in Judaism and Christianity, Muslims claim that the awaited savior in these religions is Muhammad. Muslim thinkers who believe that Muhammad was heralded in previous scripts, tried to find evidence on the subject from the Bible. One of the Islamic scholars who did researches for this purpose is Shamsuddin al-Samarqandi. Shamsuddin Mohammed b. Ashraf al-Husayni al-Samarqandi is an important Turkish-Islamic scholar who lived in Turkestan at the end of the 7th century and the first quarter of the 8th century. Samarqandi is a versatile scholar who produced important works in various fields such as philosophy, logic, mathematics, discussion, debate and astronomy. Shamsuddin al-Samarqandi is one of the eminent scholars who have written his name in the history of science and philosophy with his works. He adopted a critical and analytical style in almost every field, putting the science of logic at the center of his system. His constructive criticisms had an important function in understanding and interpreting the ideas of numerous thinkers, from Greek philosophers to Islamic philosophers and representatives of philosophical theology. In addition to all these, Samarqandi did not hesitate to criticize the Christian and Jewish belief systems, religions such as Sanawiyyah and Zoroastrianism, and the teachings of the naturalist philosophers regarding the relationship between God and the world in the light of rational and scriptural evidence. Samarqandi, who distinguished himself in rational sciences, also showed himself with his background in theology. Due to his exceptional intellectual interest, he analyzes some key concepts and divine codes related to the Bible, making original inferences about the loyalty of Muhammad, the prophet of Islam. Samarqandi interprets some passages of the Torah and the New Testament, which he considers as signs of Muhammad's prophethood, in the axis of language, logic and the rules of shariah, and concludes that Muhammad is the last prophet to be announced. The conceptual framework that he mostly focuses on in this regard contains Mount Paran, Paraklite, comparison with Moses, and the good news given to the Ishmaelites. Samarqandi makes inferences about the environment in which Muhammad appeared, his qualities, and his lineage, based on the aforementioned concepts. Samarqandi also responds to the criticisms raised by the Ahl al-Kitab about the principles, such as the abolition of other religious rules constituting the basis of Muhammad's legitimacy and establishment of Islam instead, and him being a universal prophet. An important privilege of Samarqandi is that he not only grounds his claims on a theoretical scale but also engages in debates with the leaders of the Ahl al-Kitab. Although Samarqandi exhibits a satisfactory analytical attitude in most of his claims, he displays a sophisticated approach based on the method of coercion (ilzām) in some of his claims. Although he adheres to the tradition of beshair al-nubuwwah in general, he gives a different perspective and strong reasoning to the same evidence within the tradition with the effect of his identity as a verifier (muhaqqik).
