An increasing body of evidence indicates that the response to genotoxic agents such as radiation or drugs is a group phenomenon, rather than the summed response of individual independent cells to injury. Thus, a complex contagion-like response may spread beyond the initial impact of an agent to enlarge its effect. This indirect effect, termed “Bystander Effect,” is multifaceted and may play a significant role in the therapy of tumors and in carcinogenesis. A better understanding of this phenomenon is needed in (...) order to modulate treatment protocols to therapeutic advantage and to provide more rational guidelines for the evaluation of environmental hazards.

Na samom kraju rada su razmatrana resenja koje teorija aktera-mreze nudi za odredjeni broj fundamentalnih problema sociologije, koje je definisao Latur.

There is an emerging awareness of the possibility of conflicts of interest in the practice of medicine in Croatia. The paper examines areas within the medical profession where conflicts of interest can and have occurred, probably not only in Croatia. Particularly addressed are situations when a doctor may have dual obligations and how independent ethics committees can help in decreasing the influence of a conflict of interest. The paper also presents extracts from the Croatian Code of Ethics for the medical (...) profession that address problems of conflict of interest. (shrink)

We present the basic concepts of space and time, the Galilean and pseudo-Euclidean geometry. We use an elementary geometric framework of affine spaces and groups of affine transformations to illustrate the natural relationship between classical mechanics and theory of relativity, which is quite often hidden, despite its fundamental importance. We have emphasized a passage from the group of Galilean motions to the group of Poincaré transformations of a plane. In particular, a 1-parametric family of natural deformations of the Poincaré group (...) is described. We also visualized the underlying groups of Galilean, Euclidean, and pseudo-Euclidean rotations within the special linear group. (shrink)

Horgan believes that the truth of the statement “Beethoven’s fifth symphony has four movements” does not require that there be some “dedicated object” answering to the term “Beethoven’s fifth simphony”. To the contrary, the relevant language/world correspondence relation is less direct than this. Especially appropriate is the behavior by Beethoven that we would call “composing his fifth symphony”. Our objections go along two directions: (1) is the process ontology (a) really a right kind of ontology for artworks (symphonies, novels) and, (...) (b) more important, is this kind of ontology compatible with Parmenidian approach to ontology? The answer to (a) is negative. With reference to point (1b) we might say that Parmenides was a typical staunch advocate of substance metaphysics rather than process metaphysics. Traditionally, substances are individuated by their properties, namely, there are assumed two sorts of properties: primary and secondary. Primary properties describe the substance as it is in and by itself; secondary properties underlie the impact of substances upon others and the responses they elicit from them. (2) The claim that it is most unlikely to suppose that we can have some kind of cognitive contact “with an entity which has no spatio-temporal location and does not causally interact with anything” does not hold. We underpin the claim that there is some cognitive access to entity such as Beethoven’s fifth symphony with Bender’s theory of realization relation between musical work and performance. (shrink)

There is widespread view among numerous aestheticians that aesthetic and value properties are response-dependent. According to some philosophers the dependence has a rich and multilayered structure: value qualities (e.g. beauty) depend on our response to aesthetic properties (e.g. harmonious), which in turn depend on our response to a pattern of primary and secondary qualities (shapes and colors). Secondary qualities are themselves response-dependent. The basic dependence relation is thus iterated. The resulting structure is one of iterated response-dependence. The integral part of (...) such a position is a relational view, best captured by the response-dispositional analysis: My states of being appeared to magnificently in front of a painting manifests the disposition of painting to induce such experience in the normal viewer.There are two main objections against the dispositional analysis: (1) argument from circularity and (2) argument from introducing two kinds of quality, one categorical, for experiential states, and one dispositional for objects. In this paper we will suggest the arguments against second objection. (shrink)

The paper deals with the topic of empty terms as considered in chapter six of Devitt’s book Designation. Devitt’s proposal is that a statement about fiction is (usually) implicitly preceded by a fiction operator roughly paraphrasable by “it is pretended that” or “in fiction”. The causal chain that forms the network for a fictitious name are not d(esignational)-chains, for they are not grounded in an object. Nevertheless, although the fictitious name does not designate, we could say that it stands in (...) some other referential relationship to the world: it ‘F(ictionally)-designates’. It seem that we could then state truth conditions of a F-sentence using F-designation: the F-operator direct us to look not for the designatum of name but for its F-designatum. The name (for example, “Napoleon” in War and Peace), though nonempty, is just like a fictitious name. In proposing that nonempty names in fiction refer to real items, I argue against the view that “Napoleon” in the War and Peace designates the famous general, Napoleon, and F-designates parts of War and Peace. The referent of F-designation is Napoleon, famous general, too. At the end of the paper I claim that Devitt, if he wants to remain a modal fictionalist, has to renounce the view of one-world metaphysics. (shrink)

The present study aims to identify contextual and psychological factors of proneness to radicalization and violent extremism operationalized through the Militant Extremist Mindset scale consisting of three distinct aspects: Proviolence, Vile World beliefs, and trust in Divine Power. A community sample of 271 high school students from Belgrade and Sandžak regions in Serbia completed: a 24-item MEM scale; contextual measures including a 6-item scale of family dysfunction and a 4-item composite measure capturing exposure to a harsh school environment and peer (...) abuse ; psychological measures including the 9-item Right-Wing Authoritarianism scale, the 5-item Social Dominance Orientation scale, and the 20-item UCLA Loneliness scale. A path analysis was conducted with contextual factors on the first and psychological factors on the second level of the model predicting the three factors of MEM. LON was positively predicted by FDys and HSE, SDO by HSE only, while RWA was positively predicted by FDys only. Contextual and psychological factors accounted for 27% of the variance in PV, 15% of the variance in VW, and 31% of the variance in DP. Obtained findings reveal a complex interplay of contextual and psychological drivers in the prediction of different aspects of RVE and build upon existing knowledge on risk factors associated with RVE.

The author?s approach is based on three premises: 1. that Gajo Petrovic?s Praxis was an outstanding phenomenon in Croatian, Yugoslav and European culture, a challenge of freedom in a repressive society; 2. that there has never been such a thing as "Praxis group", "philosophers of practice" or "Praxis philosophers" with a unified philosophical and socio-theoretical orientation; and 3. that political and ideological attacks on Praxis were part of the repressive system that targeted every instance of cultural and scientific dissent. The (...) political leadership of Tito?s regime, its ideological and propaganda apparatus systematically disseminated allegations, denunciations and accusations against Praxis and Gajo Petrovic. The same style has survived through radical historical changes from the appearance of Praxis until today. The attackers have often been the same persons, with the difference that in earlier times they denounced Praxis and Gajo Petrovic as enemies of "socialism" and the "socialist self-management system", and in the changed political fashion as "servants" of Tito?s authoritarian rule. The fate of Praxis in the former regime has been triumphantly interpreted as a "family quarrel". This paper attempts a sociological analysis of the political destiny of Praxis. The analysis is essentially determined not by old and new political and ideological questionings of Praxis, but by Gajo Petrovic?s fundamental belief that there is no freedom without the human or humanity without freedom.. Osnovu autorovog pristupa cine tri stava: 1. da je Praxis Gaje Petrovica bio izuzetna pojava u hrvatskoj, jugoslovenskoj i evropskoj kulturi, izazov slobode u drustvu represije; 2. da ne postoji tako nesto kao "praxis-grupa", "filozofi prakse" ili "praxis filozofi" koji bi imali jedinstvenu filozofsku ili drustveno-teorijsku orijentaciju; 3. da su politicka i ideoloska osporavanja Praxisa bila deo represivnog sistema kojem je bilo podvrgnuto svako neistomisljenistvo u kulturi i nauci. Politicki vrh Titovog rezima, njegov ideoloski i propagandni aparat sistematski su sirili insinuacije, denuncijacije i optuzbe o Praxisu i Gaji Petrovicu, da bi taj manir u bitno promenjenim istorijskim okolnostima, trajao od pojave Praxisa do danasnjeg dana. Cesto su i akteri napada bile iste osobe, samo sto su nekada osporavali Praxis i Gaju Petrovica kao neprijatelje "socijalizma" i "sistema socijalistickog samoupravljanja", a u promenjenoj politickoj modi kao "sluge" Titove autoritarne vladavine. Sudbinu Praxisa u prethodnom rezimu slavodobitno su tumacili kao "obracun u obitelji". Rad je pokusaj socioloske analize politicke sudbine Praxisa, koju ce bitno odrediti temeljno uverenje Gaje Petrovica da nema slobode bez coveka ni ljudskosti bez slobode, a ne stara i nova politicka i ideoloska osporavanja Praxisa..

Romi su veoma disperzirana etnicka zajednica. Od kako je nad Kosovom uspostavljen medjunarodni protektorat, Romi su najbrojnija nacionalna manjina u Jugoslaviji. Kada se govori o diskriminaciji i integraciji Roma, treba imati u vidu da su do sada najcesce bili izlozeni negativnim vidovima diskriminacije, a da je integracija cesto znacila fakticku asimilaciju. Kako postoji i pozitivna diskriminacija manjinskih grupa u drustvu, ocigledno je da u osnovni pristup 'romskom pitanju' podrazumeva strateski obrat ponasanja svih drzavnih institucija i drugih drustvenih cinilaca od negativne (...) ka pozitivnoj diskriminaciji i od asimilacije ka istinskoj integraciji Roma.

On the basis of his own previous research the author examines views of Europe held by the Serbian political and cultural elite in the late 20th and early 21st century. Unable to meet the challenges of the historical moment, this elite has brought Serbia into open conflict with its closest neighbors and exposed its citizens to international sanctions. War-mongering propaganda of the major state-controlled media was developing feelings of xenophobia and frustration among citizens. The collusion between authoritarian government and war (...) profiteers was systematically destroying the lives of Serbian citizens, bringing them to the brink of material impoverishment and spiritual misery. The process of dissolution of the common Yugoslav state is coming to its end in the first decade of this century. Just as it lacked wisdom political will or strength to prevent armed conflicts and crimes, the Serbian elite today is unable to condemn war crimes, to face disastrous consequences of its own policies, and to help Serbian citizens find their way to prosperity.

In this paper we argue that predictive processing (PP) theory cannot account for the phenomenon of affect-biased attention prioritized attention to stimuli that are affectively salient because of their associations with reward or punishment. Specifically, the PP hypothesis that selective attention can be analyzed in terms of the optimization of precision expectations cannot accommodate affect-biased attention; affectively salient stimuli can capture our attention even when precision expectations are low. We review the prospects of three recent attempts to accommodate affect with (...) tools internal to PP theory: Miller and Clark’s (2018) embodied inference; Seth’s (2013) interoceptive inference; and Joffily and Coricelli’s (2013) rate of change of free energy. In each case we argue that the account does not resolve the challenge from affect-biased attention. For this reason, we conclude that prediction error minimization is not sufficient to explain all mental phenomena, contrary to the claim that the PP framework provides a unified theory of all mental phenomena or the brain ‘s cognitive functioning. Nevertheless, we suggest that empirical investigation of the interaction between affective salience and precision expectations should prove helpful in understanding the limits of PP theory, and may provide new directions for the application of a Bayesian perspective to perception.

Pregledujem sedanje slepe ulice zahodne filozofije in predlagam nov začetek. V sedanjem trenutku prevladujejo tri najmočnejše pojmovne opcije; skepticizem, kognitivni privilegij in historicizem. Prvi je škandal, drugega zavračajo vse strani, tretji pa je trenutno dokaj zanemarjen. Historicizem ali zgodovinskost - pojem, daje mišljenje notranje historizirano, da je mišljenje zgodovina - je edini velik nov prispevek moderne filozofije k glavnim pojmovnim virom zahodne tradicije. Sodobna filozofija, posebno angloameriška analitična filozofija, je v bistvu nadaljevanje filozofije 17. stoletja in predkantovske filozofije 18. stoletja, (...) ki ju begajo »nepomembnosti« 19. stoletja; kontinentalna filozofija, v glavnem francoska in nemška, pa se je zdaj pripravljena prilagoditi ahistoricizmu analitične filozofije.

Še posebej skrbno raziskujem vidike prve filozofije, zaprtih sistemov, rešitev problemov reference in predikacije, odnos med naravo in kulturo, odnos med realizmom in idealizmom in naravo ter funkcijo osebe ali sebstva. Ugotavljam, da se sodobna filozofija mora spoprijeti s prispevki Kantovega konstruktivizma in Heglove simbioze in iti preko obeh. Med dokazovanjem orišem splošno krivuljo zahodne filozofije vse do današnjih časov. (shrink)

In the current socioeconomic environment, brands increasingly need to portray societal and ethical commitments at a corporate level, in order to remain competitive and improve their reputation. However, studies that relate business ethics to corporate brands are either purely conceptual or have been empirically conducted in relation to the field of products/goods. This is surprising because corporate brands are even more relevant in the services sector, due to the different nature of services, and the subsequent need to provide a consistent (...) high-quality customer experience across all the brand–customer interactions and touch-points. Thus, the purpose of this article is to study, at a corporate brand level and in the field of services, the effect of customer perceived ethicality of a brand on brand equity. The model is tested by structural equations, using data collected for eight service categories by means of a panel composed of 2179 customers. The test of measurement equivalence between these categories is conducted using generalizability theory. Confirmatory factor analysis marker technique is applied in order to check for common method variance. The results of the hypothesized model indicate that customer perceived ethicality has a positive, indirect impact on brand equity, through the mediators of brand affect and perceived quality. However, there is no empirical evidence for a direct effect of customer perceived ethicality on brand equity. (shrink)

Unchosen transformative experiences—transformative experiences that are imposed upon an agent by external circumstances—present a fundamental problem for agency: how does one act intentionally in circumstances that transform oneself as an agent, and that disrupt one’s core projects, cares, or goals? Drawing from William James’s analysis of conversion and Matthew Ratcliffe’s account of grief, I give a phenomenological analysis of transformative experiences as involving the restructuring of systems of practical meaning. On this analysis, an agent’s experience of the world is structured (...) by practically significant possibilities that form organized systems on the basis of the agent’s projects and relationships. Transformative experiences involve shifts to systems of possibility, that is, changes to habitual meanings and to how an agent’s projects are situated in relation to one another. I employ the enactivist notion of sense-making to analyze how an agent rebuilds the meaning structures disrupted by a transformative experience. In an unchosen transformative experience, an agent adjusts to a significant disruption through a process of sense-making in precarious conditions. By establishing new patterns of bodily and social interaction with the world, one alters the practical meanings of one’s surroundings, and thereby reconstitutes oneself as an intentional agent.

In the past few decades, a growth in ethical consumerism has led brands to increasingly develop conscientiousness and depict ethical image at a corporate level. However, most of the research studying business ethics in the field of corporate brand management is either conceptual or has been empirically conducted in relation to goods/products contexts. This is surprising because corporate brands are more relevant in services contexts, because of the distinct nature of services and the key role that employees have in the (...) services sector. Accordingly, this article aims at empirically examining the effects of customer perceived ethicality in the context of corporate services brands. Based on data collected for eight service categories using a panel of 2179 customers, the hypothesized structural model is tested using path analysis. The results show that, in addition to a direct effect, customer perceived ethicality has a positive and indirect effect on customer loyalty, through the mediators of customer affective commitment and customer perceived quality. Further, employee empathy positively influences the impact of customer perceived ethicality on customer affective commitment, and customer loyalty positively impacts customer positive word-of-mouth. The first implication of these results is that corporate brand strategy needs to be aligned with human resources policies and practices if brands want to turn ethical strategies into employee behavior. Second, corporate brands should build more authentic communications grounded in their ethical beliefs and supported by evidence from actual employees. (shrink)

In an ever more transparent, digitalized, and connected environment, customers are increasingly pressuring brands to embrace genuine corporate social responsibility practices and co-creation activities. While both CSR and co-creation are social and collaborative processes, there is still little research examining whether CSR can boost co-creation. In addition, while previous research has mainly related co-creation to emotional outcomes, limited empirical research has related it to rational and behavioral outcomes. To address these shortcomings in the literature, this paper examines the influence of (...) CSR on customer loyalty, considering the mediating roles of co-creation and customer trust. It also investigates the influence of co-creation on customer trust. The data were collected in Spain in late 2017 using an online survey, and the sample contained 1101 customers of health insurance services brands. Structural equation modeling was used to test the hypothesized relationships simultaneously. The results show that CSR influences customer loyalty both directly and indirectly through co-creation and customer trust. However, the indirect impact is the stronger of the two, implying that embracing co-creation activities and developing customer trust can make it easier for CSR practices to enhance customer loyalty. In addition, co-creation has a direct effect on customer trust. (shrink)

In order to be competitive in an era of ethical consumerism, brands are facing an ever-increasing pressure to integrate ethical values into their identities and to display their ethical commitment at a corporate level. Nevertheless, studies that relate business ethics to corporate brands are either theoretical or have predominantly been developed empirically in goods contexts. This is surprising, because corporate brands are more relevant in services settings, given the nature of services, and the fact that services settings comprise a greater (...) number of customer–brand interactions and touch points than goods contexts. Accordingly, the purpose of this article is to empirically examine the effects of customer perceived ethicality of corporate brands that operate in the services sector. Based on data collected for eight service categories using a panel of 2179 customers, the hypothesized structural model is tested using path analysis. The generalizability theory is applied to test for measurement equivalence between these categories. The results of the hypothesized model show that, in addition to a direct impact, customer perceived ethicality has a positive and indirect impact on brand equity, through the mediators of recognition benefits and brand image. Moreover, brand heritage negatively influences the impact of customer perceived ethicality on brand image. The main implication is that managers need to be aware of the need to reinforce brand image and recognition benefits, as this can facilitate the translation of customer perceived ethicality into brand equity.

The topic of this paper is the role played by context in art. In this regard I examine three theories linked to the names of J. Levinson, G. Currie and D. Davies. Levinson’s arguments undermine the structural theory. He finds it objectionable because it makes the individuation of artworks independent of their histories. Secondly, such a consequence is unacceptable because it fails to recognise that works are created rather than discovered. But, if certain general features of provenance are always work-constitutive, (...) as it seems that Levinson is willing to claim, these features must always be essential properties of works. On the other hand, consideration of our modal practice suggests that whether a given general feature of provenance is essential or non-essential depends upon the particular work in question or is “work relative”. D. Davies builds his performance theory on the basis of the critical evaluation of Currie’s action-type hypotheses (ATH). Performances, says Davies, are not to be identified with “basic actions” to which their times belong essentially, but with “doings” that permit of the sorts of variation in modal properties required by the work-relativity of modality. He is also a fierce critic of the contextualist account. Contextualism is in his view unable to reflect the fact that aspects of provenance bear upon our modal judgements with variable force. In the second part of the paper I consider Davies’s “modality principle”. Davies is inclined to defend the claim that labels used for designation of works are rigid designators. Such a view offers a ground for discussion about the historicity of art. What has been meant when people claim that art is an historical concept? I argue that any historical theory implies a two-dimensional notion of “art”. At the end of the paper I suggest that Davies should embrace the theory of contingent identity and not the colocationist view about the relationship that exists between a particular artwork and its physical bearer.

We introduce a probabilistic extension of propositional intuitionistic logic. The logic allows making statements such as P≥sα, with the intended meaning “the probability of truthfulness of α is at least s”. We describe the corresponding class of models, which are Kripke models with a naturally arising notion of probability, and give a sound and complete infinitary axiomatic system. We prove that the logic is decidable.

Emotionally arousing events reach awareness more easily and evoke greater visual cortex activation than more mundane events. Recent studies have shown that they are also perceived more vividly and that emotionally enhanced perceptual vividness predicts memory vividness. We propose that affect-biased attention (ABA) – selective attention to emotionally salient events – is an endogenous attentional system tuned by an individual's history of reward and punishment. We present the Biased Attention via Norepinephrine (BANE) model, which unifies genetic, neuromodulatory, neural and behavioural (...) evidence to account for ABA. We review evidence supporting BANE's proposal that a key mechanism of ABA is locus coeruleus–norepinephrine (LC–NE) activity, which interacts with activity in hubs of affective salience networks to modulate visual cortex activation and heighten the subjective vividness of emotionally salient stimuli. We further review literature on biased competition and look at initial evidence for its potential as a neural mechanism behind ABA. We also review evidence supporting the role of the LC–NE system as a driving force of ABA. Finally, we review individual differences in ABA and memory including differences in sensitivity to stimulus category and valence. We focus on differences arising from a variant of the ADRA2b gene, which codes for the alpha2b adrenoreceptor as a way of investigating influences of NE availability on ABA in humans. (shrink)
