A method is presented to compute the electron-optical phase shift for a magnetized polyhedral nanoparticle, with either a uniform magnetization or a closure domain . The method relies on an analytical expression for the shape amplitude, combined with a reciprocal-space description of the magnetic vector potential. The model is used to construct two building blocks from which more complex structures can be generated. Phase computations are also presented for the five Platonic and 13 Archimedean solids. Fresnel and Foucault imaging mode (...) simulations are presented for a range of particle shapes and microscope imaging conditions. (shrink)

The study aimed to identify the relationship between correcting the deviations in the measurement of performance and achieving the objectives of control and the performance of the job at the Islamic University in the Gaza Strip. To achieve the objectives of the research, the researchers used the descriptive analytical approach to collect information. The questionnaire consisted of (20) statements distributed to three categories of employees of the Islamic University (senior management, faculty members, their assistants and members of the administrative board). (...) A random sample of 314 employees was selected and 276 responses were retrieved with a recovery rate of 88.1%. The Statistical Analysis Program (SPSS) was used to enter, process, and analyze the data. The results of the study showed a positive relationship between correcting deviations in performance measurement and achieving the control objectives represented by the functional performance in the Islamic University from the point of view of the members (senior management, faculty and their assistants, and the administrative board), where the relative weight of all the paragraphs was (74.25%). The study recommended the need to ensure that the actual performance of the planned performance is matched and decisions are taken to correct the serious deviations and take the necessary measures in terms of retraining and change in regulations, wages and bonuses and punishment of the culprit, neglect and negligence by mistake.

We review some of the essential novel ideas introduced by Bohm through the implicate order and indicate how they can be given mathematical expression in terms of an algebra. We also show how some of the features that are needed in the implicate order were anticipated in the work of Grassmann, Hamilton, and Clifford. By developing these ideas further we are able to show how the spinor itself, when viewed as a geometric object within a geometric algebra, can be given (...) a meaning which transcends the notion of the usual metric geometry in the sense that it must be regarded as an element of a broader and more general pregeometry.

A (...) random sample of (314) employees was selected and 276 responses were retrieved with a recovery rate of 88.1%. The Statistical Analysis Program (SPSS) was used to enter process and analyze the data. The results of the research showed a positive role between measuring and evaluating the performance and achieving the objectives of the control of performance in the Islamic University from the point of view of the members (senior management, faculty and their assistants, and members of administrative board). The researchers also recommended a number of recommendations, most notably the provision of an appropriate level of the elements of the control systems today through the modernization and continuous development of performance measures and the need to provide the physical and financial resources necessary to continue the development and achievement within the university, to expand the development of technology in the various activities of the university through the construction of a complete and integrated system to support supervision systems in the university to suit the size of the university. The researchers also recommended following up and reviewing the performance measures and work to modify them in line with the mission and the goals of the university that it seeks to reach. (shrink)

_Purpose._ The purpose is to justify the validity of interpreting Descartes’ teachings as an enquiry into the search for forms and means of improving human nature, which implies a focus on the way he understands the openness of knowledge and education. The problem is considered from the perspective of representatives of university communities (teachers and librarians), historically included in the communication structure and system of the institution, including through the creation, management, use, preservation and dissemination of knowledge. _Theoretical basis._ One (...) of the tenets of Descartes’ teachings is his desire to improve the human being. For our consideration, it is fundamentally important that Descartes uses "knowledge" not only in a narrow sense – as natural scientific knowledge, but also in a broader sense. In the context of the theme of the study, the most important case is when the thinker recalls the knowledge that every person experiences without referring to philosophy. It is this knowledge that, for Descartes, is key in resolving the central problem of his ethics – how can human nature be perfected? For our consideration of Descartes’ key points, it is fair to focus on the manifestation of the phenomenon of altruism in Descartes’ philosophy and on the representative fact of his inner openness – his willingness to engage in dialogue. He appreciates and encourages his interlocutors to turn to books, which are a form of representation of the vivid personalities of their authors. _Originality._ For the first time in the research literature, the thesis of René Descartes as one of the forerunners of the open knowledge system is substantiated. The arguments are given for the validity of Descartes’ interpretation of the demand of his own epoch for the search of effective forms of human improvement. _Conclusions._ The idea of justification of Descartes’ philosophical legacy as a predictor of open knowledge became possible under the condition of paying attention to the anthropological turn he made and finding substantive analogues of openness, including open education. Drawing on Christianity as the basis for altruism, Descartes demonstrates a caring attitude towards the achievements of previous generations on the path of personal self-development. His attention is rightly drawn to education and books as representations of vibrant personalities. Their authentic and productive assimilation is possible only under the condition of a caring attitude towards the public good, which involves the intellectual volunteering of teachers and librarians. It is about self-realization through altruistic self-improvement, i.e. intellectual charity, which is especially evident today during martial law in Ukraine and is voluntary, conscious and free work for the benefit of others.

Since Aristotle and the Stoa, there has been a clash, worsened by modern predicate logic, between logically defined operator meanings and natural intuitions. Pragmatics has tried to neutralize the clash by an appeal to the Gricean conversational maxims. The present study argues that the pragmatic attempt has been unsuccessful. The “softness” of the Gricean explanation fails to do justice to the robustness of the intuitions concerned, leaving the relation between the principles evoked and the observed facts opaque. Moreover, there are (...) cases where the Gricean maxims fail to apply. A more adequate solution consists in the devising of a sound natural logic, part of the innate cognitive equipment of mankind. This account has proved successful in conjunction with a postulated cognitive mechanism in virtue of which the universe of discourse is stepwise and recursively restricted, so that the negation selects different complements according to the degree of restrictedness of Un. This mechanism explains not only the discrepancies between natural logical intuitions and known logical systems; it also accounts for certain systematic lexicalization gaps in the languages of the world. Finally, it is shown how stepwise restriction of Un produces the ontogenesis of natural predicate logic, while at the same time resolving the intuitive clashes with established logical systems that the Gricean maxims sought to explain.

This study investigates how background music influences learning with respect to three different theoretical approaches. Both the Mozart effect as well as the arousal-mood-hypothesis indicate that background music can potentially benefit learning outcomes. While the Mozart effect assumes a direct influence of background music on cognitive abilities, the arousal-mood-hypothesis assumes a mediation effect over arousal and mood. However, the seductive detail effect indicates that seductive details such as background music worsen learning. Moreover, as working memory capacity has a crucial influence (...) on learning with seductive details, we also included the learner’s working memory capacity as a factor in our study. We tested 81 college students using a between-subject design with half of the sample listening to two pop songs while learning a visual text and the other half learning in silence. We included working memory capacity in the design as a continuous organism variable. Arousal and mood scores before and after learning were collected as potential mediating variables. To measure learning outcomes we tested recall and comprehension. We did not find a mediation effect between background music and arousal or mood on learning outcomes. In addition, for recall performance there were no main effects of background music or working memory capacity, nor an interaction effect of these factors. However, when considering comprehension we did find an interaction between background music and working memory capacity: the higher the learners’ working memory capacity, the better they learned with background music. This is in line with the seductive detail assumption. (shrink)

SummaryIn this study recent exegetical methods such as inquiry into strophes, structure and style are applied to Psalm 16.Part I deals with the ancient crux interpretum, v.2–4a. With regard to the question whether “the holy ones” means divine powers or some category of Israelites, we militate for the latter interpretation. The psalmist addresses himself to God and those with whom he shares the land. From this position, principally chosen, he begins to meditate on his heritage.Part II shows that in the (...) corpus of the psalm, v.4bc-10, the theme “heritage” is developed in such a way that God's vicinity appears to be its fundamental value. This transposition makes it possible that the most threatening aspect of our earthly existence comes up: death. The psalmist draws the utmost consequences from God's vicinity. Since there is no limit to the length of God's protection, he is safe even from the Sheol.In Part III then we see that the praying person, carried by his personal growth, expresses in v. 11 the hope for an unassailable happiness of life, also for others.

A total of 80 authors working in a variety of scientific disciplines commented on the theoretical model of CLimate, Aggression, and Self-control in Humans (CLASH). The commentaries cover a wide range of issues, including the logic and assumptions of CLASH, the evidence in support of CLASH, and other possible causes of aggression and violence (e.g., wealth, income inequality, political circumstances, historic circumstances, pathogen stress). Some commentaries also provide data relevant to CLASH. Here we clarify the logic and assumptions of CLASH (...) and discusses its extensions and boundary conditions. We also offer suggestions for future research. Regardless of whether none, some, or all of CLASH is found to be true, we hope it will stimulate future research on the link between climate and human behavior. Climate is one of the most presing issues of our time. (shrink)

The universe, of which our domicile the planet Earth forms but a minuscule part, has an architecture that changes and has been changing in time. In other words, it has a history of evolution. Lack of experimental evidence denies us the knowledge of what the universe was like “at the time of its origin,” as discussed by Hubert Reeves in the preceding chapter. Neither do we know much about its geometry, simply because our observatories are concentrated, for all practical purposes, (...) vanishingly close to a single point in an immensity whose size can only be measured by the billions of years required by light to go from one extremity to another!

The system of clinical ethics committees (CECs) in the United Kingdom is based on goodwill. No formal requirements exist as to constitution, membership, range of expertise or the status of their recommendations. Healthcare professionals are not obliged to use CECs where they exist, nor to follow any advice received. In addition, the make-up of CECs suggests that ethics itself may be under-represented. In most cases, there is one member with a training in ethics – the rest are healthcare professionals or (...) administrators, although a lawyer is generally also included in the membership. This begs the question as whether CECs can ‘do ethics’, as well whether or not they can take seriously the requirements of due process, formal justice and human rights. Moreover, the role of the patient in this system is opaque. (shrink)

Chow's account of Bayesian inference logic and procedures is replete with fundamental misconceptions, derived from secondary sources and not adequately informed by modern work. The status of subjective probabilities in Bayesian analyses is misrepresented and the cogent reasons for the rejection by many statisticians of the curious inferential hybrid used in psychological research are not presented.

Critical literatures, and public discourses, on public health policies and practices often present fixated concerns with paternalism. In this paper, rather than focus on the question of whether and why intended instances of paternalistic policy might be justified, we look to the wider, real-world socio-political contexts against which normative evaluations of public health must take place. We explain how evaluative critiques of public health policy and practice must be sensitive to the nuance and complexity of policy contexts. This includes sensitivity (...) to the ‘imperfect’ reach and application of policy, leading to collateral effects including collateral paternalism. We argue that theoretical critiques must temper their demandingness to real-world applicability, allowing for the detail of social and policy contexts, including harm reduction: apparent knock-down objections of paternalism cannot hold if they are limited to an abstract or artificially-isolated evaluation of the reach of a public health intervention.

Contrary to received opinion, the Aristotelian Square of Opposition (square) is logically sound, differing from standard modern predicate logic (SMPL) only in that it restricts the universe U of cognitively constructible situations by banning null predicates, making it less unnatural than SMPL. U-restriction strengthens the logic without making it unsound. It also invites a cognitive approach to logic. Humans are endowed with a cognitive predicate logic (CPL), which checks the process of cognitive modelling (world construal) for consistency. The square is (...) considered a first approximation to CPL, with a cognitive set-theoretic semantics. Not being cognitively real, the null set Ø is eliminated from the semantics of CPL. Still rudimentary in Aristotle’s On Interpretation (Int), the square was implicitly completed in his Prior Analytics (PrAn), thereby introducing U-restriction. Abelard’s reconstruction of the logic of Int is logically and historically correct; the loca (Leaking O-Corner Analysis) interpretation of the square, defended by some modern logicians, is logically faulty and historically untenable. Generally, U-restriction, not redefining the universal quantifier, as in Abelard and loca, is the correct path to a reconstruction of CPL. Valuation Space modelling is used to compute the effects of U-restriction. (shrink)

Euthanasia and physician-assisted suicide are controversial issues in medical ethics and medical law. In the debate, several arguments against the moral acceptability and legal feasibility of active involvement of physicians in bringing about a patient’s death can be found.One argument refers back to the Ten Commandments: “Thou shall not kill”. Killing another human being is morally abject. According to the argument, this is certainly so for medical doctors, as can be seen in the Hippocratic Oath, which explicitly forbids abortion and (...) euthanasia. A less apodictic argument refers to the slippery slope: if euthanasia would be permitted, a downhill movement is set in motion. The end of this movement would be, on the one hand, that physicians will feel forced to assist people who ask for termination of life on whatever grounds. On the other hand, it might lead to a situation in which it becomes normal to kill people who are no longer useful for society.In the literature and in the public debate, there are also arguments in favour of euthanasia and physician-assisted suicide. One such argument invokes the right to die. According to this argument, decisions concerning life and death should be up to the individual who is concerned. In many countries, suicide is morally and legally accepted. If people are allowed to kill themselves, why should they be without rights when they are no longer able to perform the act themselves?In medical ethics and medical law, patient autonomy is a central pivot. Patients have the right to refuse treatment even if this leads to their death. Shouldn’t people also have the right to determine the moment of dying, if they are in a situation which is unbearable, and without prospect of improvement? Another argument focuses on the duty of the physician to alleviate pain and suffering. If there is no other option, the doctor, in fulfilling this duty, should be allowed to actively end the patient’s life. This argument is not based on autonomy, but on beneficence.The debate concerning euthanasia involves fundamentally different moral principles. This makes the debate interesting, if not central to medical ethics and medical law. Yet, the principles are normally presented in an abstract way. Discussants stick to very general ideas, which lack reference to specific social and historical conditions, and are not related to concrete experiences. To invoke the Ten Commandments, or plea for a right to die, implies the use of universal standards, which tend to be general and empty.From a philosophical perspective, this type of argumentation can be criticized. Following Aristotle, ethics should be based upon experience. Ethical knowledge requires participation in concrete practices. Central to ethics is a feeling for the concrete situation, which is always contingent and historical. From this perspective, it makes sense to consider how practitioners in specific situations deal with moral issues, for instance concerning euthanasia. What role do they give to notions such as autonomy and beneficence, how do they interpret them and apply them to the concrete situation?In this paper I will present the Dutch experience with euthanasia. I will focus upon the way in which during the past thirty years the arguments in favour of euthanasia have been developed, in interaction with euthanasia practice. I will show that patient autonomy has been a crucial pivot. Yet, the Dutch interpretation of autonomy is not purely liberal. It does not only involve rights, but also obligations. Next, I will make clear that the physician plays a central role, in that the moral and legal basis of euthanasia is a conflict of duties on the side of the physician.This brings in the issue of beneficence. Yet the Dutch interpretation of the duty to help is not simply paternalistic. In Dutch health care, the physician-patient relationship is based upon deliberation and mutual agreement. Therefore, my conclusion will be that the Dutch practice of euthanasia has a moral ground, which goes beyond the traditional opposition between autonomy and beneficence. (shrink)

This is the first of a two-volume monograph on the Unification of Artificial Intelligence and Psychology. It unifies the topics of representation, meaning, thinking, communication, and understanding. Such a unification requires the establishment of a novel, fully explicated, theoretical construct —noémon system— that replaces all the inadequately developed concepts that historically have been used as constitutive notions of cognitive science. The space of noémon systems encompasses an awe-inspiring variety of noémon species and an increasing variety of artificially noémon entities and (...) hybrid noémon systems. As such, it is a superspace of the space of phenomena addressed by cognitive science. The theory of noémon systems (TNS) described in this two-volume monograph is envisaged as the first step towards an emerging science of noémon systems. (shrink)

Plamondon & Alimi's model will gain substantially in credibility when it is able to come up with predictions for new (rather than old) experimental results that discriminate between various models. Moreover, the present model is nothing more than a descriptive not an explanation for motor performance. A link to the contribution of various neuronal mechanisms involved in motor control and of muscle properties to the performance of the model is crucial.

Attempts to introduce phenomenology to the English-speaking world have often been hampered by the specialist's tendency to substitute a part for the whole--thereby threatening the delicate balance guaranteed by the transcendental turn and so carefully maintained by Husserl throughout his-philosophical career. Thus some, in their concern to place Husserl in the context of the realism-idealism issue, have stressed the contrast between Ideen and some aspects of Krisis. Others, relying on the illuminating power of the notion of human roles, have devoted (...) themselves exclusively to the working out of a mundane phenomenology with or without ontological pretensions. While there is value to be found in this branching out of the research, it nevertheless needs to be integrated. Because of the character of the phenomenological synthesis, moreover, such integration cannot be achieved simply by generalists. Hence the value of scholars like Kockelmans whose experience in more than one type of reduction permits them to move readily from one level of intentionality to another. As the book amply demonstrates, Kockelmans has acquired this multiple capability by following in detail Husserl's philosophical development as it progressively opens the way to the exploration of all these levels. In commenting upon this development, he is also rendering an invaluable service by bringing to light many of Husserl's writings which otherwise might remain unknown to the interested student. The work is concise, a model of balance between exposition of the doctrine and clarification of the issues; in short, an excellent and welcome addition to the phenomenological literature.-A. M.
