Politics appears to have a direct impact on the quality of our lives as citizens of states. We outline here the dependence between culture and its inherent mechanism of forgetting, and between a hero and a political subject. We employ the theory of Juri Lotman, who underlines the role of individuals and of single events in culture. The primary illustration given is the figure of Lech Wałęsa, politician, legendary co-founder of the Solidarity trade union, and Nobel Peace Prize winner. He (...) exemplifies Lotman’s notion of a mobile hero, one who powered the course of history, but whose present-day political and social activity is of an empty and querulous nature, lacking a goal and deeper meaning, while the actions he performs take place within a closed semantic field. He is an example of a paradoxical hero, whose actions no longer generate tensions or build a new semiotic quality. Wałęsa’s problem is the ossification of his discourse and failure to perceive that transformation has already taken place. (shrink)

There has been a growing interest in research concerning memory modification technologies (MMTs) in recent years. Neuroscientists and psychologists are beginning to explore the prospect of controllable and intentional modification of human memory. One of the technologies with the greatest potential to this end is optogenetics—an invasive neuromodulation technique involving the use of light to control the activity of individual brain cells. It has recently shown the potential to modify specific long-term memories in animal models in ways not yet possible (...) with other MMTs. As the therapeutic potential of optogenetics has already prompted approval of the first human trials, it is especially important and timely to consider the opportunities and dangers this technology may entail. In this article, we focus on possible consequences of optogenetics as an MMT by analyzing fundamental threats potentially associated with memory modifications: the potential disruption of personality and authenticity.

Optogenetics is an invasive neuromodulation technology involving the use of light to control the activity of individual neurons. Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans. As optogenetics is being intensively investigated in animal models with the aim of developing novel brain stimulation treatments for various neurological and psychiatric disorders, it appears crucial to consider both the opportunities and dangers (...) such therapies may offer. In this review, we focus on the memory-modifying potential of optogenetics, investigating what it is capable of and how it differs from other memory modification technologies. We then outline the safety challenges that need to be addressed before optogenetics can be used in humans. Finally, we re-examine crucial neuroethical concerns expressed in regard to other MMTs in the light of optogenetics and address those that appear to be unique to the memory-modifying potential of optogenetic technology.

The philosophical activities during the Safavid era mark the peak of a renewed engagement with Greek sources unmediated by Ibn Sina's interest in them and their successive incorporation into his philosophy.1 Among the topics for which the Safavid thinkers consulted ancient Greek authors were cosmology, the role of the intellect and the ways of acquiring knowledge, the nature of the soul, and the process of emanation.2 This engagement, to be sure, did not mean an antiquarian, philological return to the original (...) texts in Greek. Rather, it was a re-reading of their Arabic translations from the ninth to tenth centuries to find ideas beyond those of which Ibn Sina made use, and to legitimize—through their... Read More.

İbn Sînâ, Yeter Sebep İlkesi’ni (YSİ), yani her şeyin bir sebebi olduğu ve sebepsiz hiçbir varlığın var olamayacağı iddiasını savunan modern dönem öncesi filozoflarından biridir. YSİ’nin sonuçlarından biri de zorunlulukçuluktur (necessitarianism); yani gerçekte var olan her şeyin aynı zamanda zorunlu olarak var olduğu iddiasıdır. Bu fikre göre sebepler zincirinin her bir üyesi kendinden önceki sebepler tarafından belirlenir. Dolayısıyla YSİ, olayların başka türlü de olabileceğini telkin eden insan sezgisine karşı çıkmaktadır. Bu çalışmadaki amacım, İbn Sînâ sonrası yazarların insan iradesini dışlamak suretiyle (...) YSİ’nin zorunlulukçu sonuçlarını hafifletmeye çalışıp çalışmadıklarını araştırmaktır. Nasîrüddin Tûsî’nin (ö. 672/1274) Cebr ve Kader adlı Farsça risalesi ile Tecrîdü’l-i‘tikâd adlı kelâm kitabı arasında bir karşılaştırma yapmaya odaklanacağım. Bu konuyu seçmemin öncelikli sebebi, insanların eylemlerinin bağımsız fâilleri olduklarını sezgisel olarak bildiklerine dair Tûsî’nin iddialarıdır ki bu, YSİ‘nin evrensel uygulanabilirliği ile çelişiyor gibi görünmektedir. Tûsî’nin özgür irade konusunda, metinlerin karakterine ve yazıldıkları döneme bağlı olarak, bazen İbn Sînâ ile tutarlılık arzeden bazen de Mu‘tezile’ye angaje olan farklı görüşler benimsediğini savunacağım. Tûsî’nin, bazen nedensel olarak etkin olmamasına rağmen insan özgürlüğüne nasıl yer bıraktığını göstereceğim. O, insan özgürlüğünü, insanın karşı karşıya kaldığı fiziksel veya ilahî diğer belirlenim türlerinden bağımsız olarak hareket edebilen farklı bir belirlenim türü olarak anlar. Genel olarak bu mesele, Tûsî’nin İbn Sînâ felsefesine ya da Şiî kelâmına bağlılığını test etmekte ve hatta onu bazı eserlerinde İbn Sînâ’nın bilgi görüşüne karşı bir duruş sergilemeye zorlamaktadır.

We discuss applications of our account of moral status grounded in person-rearing relationships: which individuals have higher moral status or not, and why? We cover three classes of cases: (1) cases involving incomplete realization of the capacity to care, including whether infants or fetuses have this incomplete capacity; (2) cases in which higher moral status rests in part on what is required for the being to flourish; (3) hypothetical cases in which cognitive enhancements could, e.g., help dogs achieve human-like cognitive (...) capacities. We thereby show that our account does not have the counterintuitive implications alleged by DeGrazia and other critics. (shrink)

Due to advances in medicine, a malignant neoplasm is a chronic disease that can be treated for a lot of patients for many years. It may lead to profound changes in everyday life and may induce fear of life. The ability to adjust to a new situation may depend on temperamental traits and stress coping strategies. The research presented in this paper explores the relationships between quality of life, PTSD symptoms, temperamental traits, and stress coping in a sample of patients (...) diagnosed with cancer. One hundred and twenty nine participants aged 24–81 years, 69 females diagnosed with breast cancer and 60 males diagnosed with lung cancer completed Formal Characteristics of Behavior – Temperament Inventory, Coping Inventory for Stressful Situations, PTSD Inventory, and Quality of life SF-36 questionnaire. Higher level of emotional reactivity and higher level of perseveration was associated with lower emotional quality of life. Higher level of emotion oriented-coping and higher level of avoidant-distracted coping was associated with higher level of PTSD symptoms. Emotion-oriented coping and avoidant-distracted coping are ineffective in dealing with stress in the case of patients diagnosed with cancer, because they are associated with a higher level of PTSD symptoms. The significance of temperamental traits for quality of life in the situation of the patients is marginal. Control of specific factors concerned with current health and treatment status is needed the future research. (shrink)

Although there is much research on the relationships of corporate social responsibility and employee-related outcomes, a systematic and quantitative integration of research findings is needed to substantiate and broaden our knowledge. A meta-analysis allows the comparison of the relations of different types of CSR on several different outcomes, for example to learn what type of CSR is most important to employees. From a theoretical perspective, social identity theory is the most prominent theoretical approach in CSR research, so we aim to (...) investigate identification as a mediator of the relationship between CSR and employee-related outcomes in a meta-analytical mediation model. This meta-analysis synthesizes research findings on the relationship between employees' perception of CSR (people, planet, and profit) and employee-related outcomes (identification, engagement, organizational attractiveness, turnover (intentions), OCB, commitment, and job satisfaction), thereby distinguishing attitudes and behavior. A total of 143 studies (N= 89,396) were included in the meta-analysis which was conducted according to the methods by Schmidt and Hunter (except of the meta-analytical structural equation model). Mean effect sizes for the relationship between CSR and employee-related attitudes and behaviors were medium-sized to large. For attitudes, the relationships were stronger than for behavior. For specific types of CSR, average effect sizes were large. Identification mediated the relation between CSR and commitment, job satisfaction, and OCB, respectively. Based on our results, we give recommendations concerning the design of CSR initiatives in a way that benefits employees. (shrink)

The purpose of the article is to contribute to the discussion about the relevance of existential issues in contemporary education. Analysis presented in the paper is related to the problems of self-awareness, becoming oneself and self-development. First, the author begins by depicting the meaning of human existence in the light of philosophy. The following aspects have been analyzed: being true to one’s own beliefs and values, recognizing personal truth, making existential choices and finding one’s own voice. A special attention is (...) paid to the language as an essential, constitutive element of being. Second, the article attempts to consider some educational implications resulting from the existential approach to education. Some of the issues discussed are learning to philosophize and to discover meaning, the concept of encounter in education and the role of language in self-development. While describing them the author indicates that the ignoring of crucial existential questions in education contributes to spiritual vacuity in life of young people and reduces educational thinking merely to instrumental, pragmatic problems concerning qualification and transfer of communicative skills.

While issues of efficacy and specificity are crucial for the future of neurofeedback training, there may be alternative designs and control analyses to circumvent the methodological and ethical problems associated with double-blind placebo studies. Surprisingly, most NF studies do not report the most immediate result of their NF training, i.e. whether or not children with ADHD gain control over their brain activity during the training sessions. For the investigation of specificity, however, it seems essential to analyze the learning and adaptation (...) processes that take place in the course of the training and to relate improvements in self-regulated brain activity across training sessions to behavioral, neuropsychological and electrophysiological outcomes. To this aim, a review of studies on neurofeedback training with ADHD patients, which include the analysis of learning across training sessions or relate training performance to outcome, is presented. Methods on how to evaluate and quantify learning of EEG regulation over time are discussed. “Non-learning” has been reported in a small number of ADHD-studies, but has not been a focus of general methodological discussion so far. For this reason, selected results from the brain-computer interface (BCI) research on the so-called “brain-computer illiteracy”, the inability to gain control over one’s brain activity, are also included. It is concluded that in the discussion on specificity, more attention should be devoted to the analysis of EEG regulation performance in the course of the training and its impact on clinical outcome. It is necessary to improve the knowledge on characteristic cross-session and within-session learning trajectories in ADHD and to provide the best conditions for learning. (shrink)

In his work on internality, identification, and caring, Harry Frankfurt attempts to delineate the organization of agency peculiar to human beings, while avoiding the traditional overintellectualized emphasis on the human capacity to reason about action. The focal point of Frankfurt’s alternative picture is our capacity to make our own motivation the object of reflection. Building upon the observation that marginal agents (such as young children and Alzheimer’s patients) are capable of caring, I show that neither caring nor internality need to (...) depend on the phenomena of reflectiveness. I develop alternative interlocking accounts of caring and internality that are independent of both reflectiveness and evaluation, but that can still do justice to the central role of carings in the organization of agency characteristic of human persons.

A being has moral standing if it or its interests matter intrinsically, to at least some degree, in the moral assessment of actions and events. For instance, animals can be said to have moral standing if, other things being equal, it is morally bad to intentionally cause their suffering. This essay focuses on a special kind of moral standing, what I will call “full moral standing” (FMS), associated with persons. In contrast to the var- ious accounts of what ultimately grounds (...) FMS in use in the philosophical literature, I will propose that the emotional capacity to care is a sufficient condition of an individual’s FMS as a person. In developing this account, I will appeal to a set of intuitions not previously mined for this purpose: those generated by conflicts of interests between different life phases of a single individual.

Why does a baby who is otherwise cognitively similar to an animal such as a dog nevertheless have a higher moral status? We explain the difference in moral status as follows: the baby can, while a dog cannot, participate as a rearee in what we call “person-rearing relationships,” which can transform metaphysically and evaluatively the baby’s activities. The capacity to engage in these transformed activities has the same type of value as the very capacities (i.e., intellectual or emotional sophistication) that (...) explain unimpaired adult humans’ high moral status. We attempt to extend this account to individuals with severe cognitive impairments. (shrink)

The material subject of Catholic social science is man and his actions taken in the fields of politics, the economy and society. According to its rules each person should be engaged in building the world through the realization of his or her vocation. One kind of vocation might be leading people by acting in accordance with the Gospel and teachings of the Church. The most important values for the leader in this case would be: respect for human dignity and human (...) rights, freedom, justice, the subsidiarity principle and cooperation due to creating the common good. The listed rules are realized by servant leadership, the idea functioning in the field of management that derives its origins from Christ’s speech: whosoever will be chief among you, let him be your servant (Mt 20:27).

People should be at the centre of attention within knowledge-based economics. The leaders of each enterprise ought to focus on providing the best conditions for their employees’ professional and individual development and treat them with respect in terms of their dignity and needs. In contemporary literature two notions in perceiving people in organisations are noticeable. The first one treats employees as ‘resources’ which have to be properly used or as ‘capital’ that should bring a decent return on investment. The second (...) notion derives a lot from Christian philosophy and sees the human as a person who treats work as a way to realize his calling and thus is able to take responsibility for the decisions made and actions taken. Acting in a constantly changing environment, people have to be flexible and able to take advantage of emerging opportunities and avoid threats. Within this process it is not a matter of being a human ‘being’ but rather becoming, which means that they are incessantly developing their potential. Although it is hard to predict human behaviour, the main task for managers is to lead in a way that will help employees use their full potential for both their own and the company’s benefit.

The main aim of the paper is to show an existential religious model of business leadership. We want to defend the thesis that leaders, who consider existing norms and regulations, have the greatest influence on how organisational aims are achieved. Thus, based on the concept of Kierkegaard’s modes of existence, we show that the individual values and motives of leaders’ behaviour influence the shape of the leadership itself as well as the management of an organisation. On the basis of a (...) literature review, we propose the following connections: an aesthetic mode with instrumental motives which result in the shareholder perspective; an ethical mode of existence with normative motives which lead to the stakeholder perspective; and the spiritual mode of existence with transcendental motives which enable leaders to introduce a holistic perspective of management. However, we cannot link certain motives with a particular type of leadership, as leaders with different modes of existence might practice the same type of leadership (i.e., leadership based on values, authentic leadership) and combine various types of leadership in their actions. The paper might provide a theoretical basis for empirical research on leadership and managerial behaviour. (shrink)

This study examined individual differences in sensitivity to human-like features of a robot’s behavior. The paradigm comprised a non-verbal Turing test with a humanoid robot. A “programmed” condition differed from a “human-controlled” condition by onset times of the robot’s eye movements, which were either fixed across trials or modeled after prerecorded human reaction times, respectively. Participants judged whether the robot behavior was programmed or human-controlled, with no information regarding the differences between respective conditions. Autistic traits were measured with the autism-spectrum (...) quotient questionnaire in healthy adults. We found that the fewer autistic traits participants had, the more sensitive they were to the difference between the conditions, without explicit awareness of the nature of the difference. We conclude that although sensitivity to fine behavioral characteristics of others varies with social aptitude, humans are in general capable of detecting human-like behavior based on very subtle cues.

Digital communication between a patient and their clinician offers the potential for improved patient care, particularly for young people with long term conditions who are at risk of service disengagement. However, its use raises a number of ethical questions which have not been explored in empirical studies. The objective of this study was to examine, from the patient and clinician perspective, the ethical implications of the use of digital clinical communication in the context of young people living with long-term conditions. (...) A total of 129 semi-structured interviews, 59 with young people and 70 with healthcare professionals, from 20 United Kingdom -based specialist clinics were conducted as part of the LYNC study. Transcripts from five sites were read by a core team to identify explicit and implicit ethical issues and develop descriptive ethical codes. Our subsequent thematic analysis was developed iteratively with reference to professional and ethical norms. Clinician participants saw digital clinical communication as potentially increasing patient empowerment and autonomy; improving trust between patient and healthcare professional; and reducing harm because of rapid access to clinical advice. However, they also described ethical challenges, including: difficulty with defining and maintaining boundaries of confidentiality; uncertainty regarding the level of consent required; and blurring of the limits of a clinician’s duty of care when unlimited access is possible. Paradoxically, the use of digital clinical communication can create dependence rather than promote autonomy in some patients. Patient participants varied in their understanding of, and concern about, confidentiality in the context of digital communication. An overarching theme emerging from the data was a shifting of the boundaries of the patient-clinician relationship and the professional duty of care in the context of use of clinical digital communication. The ethical implications of clinical digital communication are complex and go beyond concerns about confidentiality and consent. Any development of this form of communication should consider its impact on the patient-clinician-relationship, and include appropriate safeguards to ensure that professional ethical obligations are adhered to.

This paper evaluates Richard Swinburne’s modal argument for the existence of souls. After a brief presentation of the argument, wedescribe the main known objection to it, which is called the substitution objection (SO for short), and explain Swinburne’s response to that objection. With this as background, we formalize Swinburne’s argument in a quantified propositional modal language, modifying it so that it is logically valid and contains no tacit assumptions, and we explain why we find Swinburne’s response to SO unsatisfactory. Next, (...) we indicate that, even though SO is quite compelling, a weakening of one of the premises yields a valid argument for the same conclusion which is immune to SO. This version of the argument, however, is epistemically circular. (shrink)

The aim of the paper is to examine some important features of Peirce's and Wittgenstein's accounts of the nature of signs. The analysis shows that there are at least four points, regarding the nature of signs, on which Peirce and Wittgenstein agree. These are: the triadic nature of signs, the presence of degenerate signs in our discourses, the role of rules in the constitution of meaning, and the indispensable role of a community in creating and maintaining the network of signs. (...) Discovering these similarities does not mean that Peirce's and Wittgenstein's conceptions of semiotics are identical, as their authors make different assumptions about e.g. the aims of semiosis, but they nevertheless reach very similar conclusions.

Since the 1980s, there has been an increasing acknowledgement of the importance of recognising the ethical dimension of clinical decision-making. Medical professional regulatory authorities in some countries now include ethical knowledge and practice in their required competencies for undergraduate and post graduate medical training. Educational interventions and clinical ethics support services have been developed to support and improve ethical decision making in clinical practice, but research evaluating the effectiveness of these interventions has been limited. We undertook a systematic review of (...) the published literature on measures or models of evaluation used to assess the impact of interventions to improve ethical decision making in clinical care. We identified a range of measures to evaluate educational interventions, and one tool used to evaluate a clinical ethics support intervention. Most measures did not evaluate the key impact of interest, that is the quality of ethical decision making in real-world clinical practice. We describe the results of our review and reflect on the challenges of assessing ethical decision making in clinical practice that face both developers of educational and support interventions and the regulatory organisations that set and assess competency standards.

Corporate social responsibility is widely established by companies that aim to contribute to society and minimize their negative impact on the environment. In CSR research, employees’ reactions to CSR have extensively been researched. Social identity theory is often used as a theoretical background to explain the relationship between CSR and employee-related outcomes, but until now, a sound empirical examination is lacking, and causality remains unclear. CSR can unfold its effect mainly because of three theoretically important aspects of CSR initiatives, which (...) increase identification, i.e., distinctiveness, prestige, and salience of the out-group. This study examines how far identification can explain the effect of CSR on employees. In an experimental vignette study, CSR was manipulated in three degrees to examine its effects on job satisfaction, organizational commitment, and organizational citizenship behavior. In the vignettes, information on distinctiveness, prestige, and salience of the out-group were presented. Regression analyses showed that CSR significantly predicted commitment and job satisfaction, but not OCB. We found mediation effects of CSR on commitment, job satisfaction, and OCB through identification, but the effect of CSR on identification explained only little variance which indicates additional underlying mechanisms. The applicability of social identity theory for explaining CSR is discussed. Moreover, we discuss further explaining mechanisms. (shrink)

According to Gawande, Lazaroff “chose badly.” Gawande suggests that physicians may be permitted to intervene in choices of this kind. What makes the temptation to intervene paternalistically in this and similar cases especially strong is that the patient’s choice contradicts his professed values. Paternalism appears less problematic in such cases because, in contradicting his values, the patient seems to sidestep his own autonomy. This chapter addresses the dangers of overextending this interpretation. I argue that it is not so easy to (...) judge when a person is not genuinely exercising autonomy, and that choosing contrary to one’s own values does not necessarily amount to sidestepping one’s autonomy. The key insight is to recognize the importance of the attitude of caring as an integral part of some expressions of autonomy. This will allow us to develop an alternative picture of minimal autonomy, according to which it is possible to choose against one’s values while genuinely exercising autonomy. For practical purposes, in medicine and elsewhere, this means that, in cases like Lazaroff’s, those tempted toward paternalism must exercise particular caution before they deem a choice to be disen- gaged from autonomy: even if a choice contradicts the person’s own values, it might be rooted in caring, and then, despite initial appearances to the contrary, it may still command the highest level of protection against paternalism.

This study aims at demonstrating the usefulness of the Pareto in- clusive criterion methodology for comparative analyses of fungi toxicity. The toxicity of fungi is usually measured using a scale of several ranks. In practice, the ranks of toxicity are routinely grouped into only four conventional classes of toxicity: from a class of no toxicity, low toxicity, and moderate toxicity, to a class of high toxicity. The illustrative material included the N = 61 fungi samples obtained from three species: A. (...) ochraceus, A. niger and A. flavus. In accordance with the Pareto approach, four partial criterions of the worst toxi- city were defined, a single criterion used for each conventional class of toxicity. Finally, the odds ratios (OR) were calculated separately for each partial cri- terion, and the significance of the hypotheses OR = 1 was estimated. It was stated that A. ochraceus fungi are distinctly more toxic than the two remaining ones with respect to the all considered four partial criterions, with significance equal to p = 0.04, p = 0.04, p = 0.007 and p = 0.005, respectively. Thus, the suggested method illustrated its utility in the case under study. (shrink)

Poincaré plot is a return map which can help perform graphical analysis of data. We can also fit an ellipse to the plot shape by determining descriptors SD1, SD2 and SD1/SD2 ratio to study the data quantitatively. In this paper we show examples of application of Poincaré plots in analysis of various kinds of biomedical signals: RR intervals, EMG, gait data and EHG.
