What is global supervenience?

The relation of global supervenience is widely appealed to in philosophy. In slogan form, it is explained as follows: a class of properties A supervenes on a class of properties B if no two worlds differ in the distribution of A-properties without differing in the distribution of B-properties. It turns out, though, that there are several ways to cash out that slogan. Three different proposals have been discussed in the literature. In this paper, I argue that none of them is adequate. Furthermore, I present a puzzle that reveals a tension in our concept of global supervenience.     

Global cities,global justice?

ABSTRACT

The global city is a contested site of economic innovation and cultural production, as well as profound inequalities of wealth and life chances. These cities, and large cities that aspire to ‘global’ status, are often the point of entry for new immigrants. Yet for political theorists (and indeed many scholars of global institutions), these critical sites of global influence and inequality have not been a significant focus of attention. This is curious. Theorists have wrestled with the nature and demands of global justice, but have for the most part supposed that the debate is between statist and cosmopolitan formulations. Questions of redistribution, immigration, humanitarian obligations, coercion at borders, and territorial rights have correspondingly been cast as either the domain of sovereign territorial states, or of the nascent web of supranational institutions that might bind those states and peoples, morally and legally. Examining some of these issues and arguments through the lens of the global city casts them in a new and informative light, and buttresses an associative turn in thinking about global justice.     

Do multicultural experiences facilitate global processing style?

The current research explores whether multicultural experiences facilitate global processing style. We conducted two experiments in which participants were exposed to either a multicultural experience or a monocultural experience. They were required to either perform the Navon letter task (Experiment 1) or search for similarities or differences between two videos (Experiment 2). The experimental results showed that, compared to the participants exposed to a monocultural experience, those exposed to a multicultural experience had faster reaction times to global letters (Experiment 1) and tended to search for similarities (Experiment 2). This indicates that individuals with multicultural experiences facilitate a global processing style. © 2016 John Wiley & Sons Australia, Ltd, Asian Association of Social Psychology and Beijing Normal University     

Asymmetrical hemisphere activation enhances global–local processing

Decades of research focusing on the neurophysiological underpinnings related to global–local processing of hierarchical stimuli have associated global processing with the right hemisphere and local processing with the left hemisphere. The current experiment sought to expand this research by testing the causal contributions of hemisphere activation to global–local processing. To manipulate hemisphere activation, participants engaged in contralateral hand contractions. Then, EEG activity and attentional scope were measured. Right-hand contractions caused greater relative left-cortical activity than left-hand contractions. Participants were more narrowly focused after left-hemisphere activation than after right-hemisphere activation. Moreover, N1 amplitudes to local targets in the left hemisphere were larger after left-hemisphere activation than after right-hemisphere activation. Consistent with past research investigating hemispheric asymmetry and attentional scope, the current results suggest that manipulating left (right) hemisphere activity enhanced local (global) attentional processing.

How do affected interests support global democracy?

In this paper, I critique one way of arguing for global democracy on grounds of affected interests and defend another. A famous argument for global democracy, which I call the Demos-Based Argument, attempts to justify global democracy based on the claim that affected interests vindicate individual claims to democratic participation or representation. I analyze and evaluate the Demos-Based Argument and consider different ways of interpreting and justifying its crucial premise: the Principle of Affected Interests. The result is that the argument fails. One lesson of the discussion of the Demos-Based Argument is that the most promising, though eventually unsuccessful, justification of the Principle of Affected Interests is utilitarian. Given the failure of the Demos-Based Argument, the question suggests itself if there is another way to argue for global democracy on utilitarian grounds. I will outline a promising alternative argument for global democracy, which I call the Direct Argument. Like the Demos-Based Argument, the Direct Argument is based on affected interests and ultimately on utilitarianism, but unlike the former, the Direct Argument avoids the detour over stating a criterion for individual claims to democratic participation and representation.     

Is the debate on ‘global justice’ a global one? Some considerations in view of modern philosophy in Africa

At present, the debate on global justice, a debate which is at the core of global ethics, is largely being conducted by European and American scholars from different disciplines without taking into account views and concepts from other regions of the world, particularly, from the Global South. The lack of a truly intercultural, interreligious, and international exchange of ideas provokes doubts whether the concepts of global justice introduced so far are able to transcend regional and cultural horizons. The article introduces concepts of justice from African scholars, whose voices have remained marginal until now, like the Kenyan philosopher Henry Odera Oruka, the Ethiopian philosopher Teodros Kiros, and the debate on ubuntu, one of the most controversial concepts in southern Africa today. These concepts focus on issues that are seldom considered in the debate on global justice, such as the importance of bodily needs as a prerequisite for human beings to act as moral beings and the importance of human relationships and solidarity. The last part of the article discusses factors which lead to exclusion from the academic discourse and the question how we as scholars can work for more academic justice.     

Local form–motion interactions influence global form perception

Object motion perception depends on the integration of form and motion information into a unified neural representation. Historically, form and motion perception are thought to be independent processes; however, research has demonstrated that these processes interact in numerous and complex ways. For example, an object??s orientation relative to its direction of motion will influence its perceived speed (Georges, Seriès, Frégnac, & Lorenceau, Vision Research 42:2757?C2772, 2002). Here, we investigated whether this local form?Cmotion interaction influences global form processing. In Experiment 1, we replicated the effect of orientation-dependent modulation of speed. In Experiment 2, we investigated whether the perceived speed of local elements could influence the perceived shape of a global object constructed from grouping of those elements. The results indicated that the orientation of local elements indeed influenced the perceived shape of a global object. We propose that inputs from local form?Cmotion processes are one of perhaps many neural mechanisms underlying global form integration.     

Do the global advantage and interference effects covary?

The global precedence hypothesis has been operationally defined as a faster or earlier processing of the global than of the local properties of an image (global advantage) and as interference by processing at the global level with processing at the local level (global interference). Navon (1977) proposed an association between the global advantage and interference effects. Other studies have shown a dissociation between the two effects (e.g., Lamb & Robertson, 1988). It seems that the controversy in previous research resulted from not equalizing the eccentricities of global and local properties. In the present study, the eccentricities of the two levels were equalized by using stimuli with all their elements located along their perimeters. The results of the first experiment demonstrated that although the global level was identified faster than the local level in both the central and the peripheral locations of the visual field (global advantage), the pattern of global interference varied across the visual field. Consistency of global and local levels increased the speed of processing of the local level displayed at the center of the visual field but slowed down the processing of that level at peripheral locations. The results of Experiment 2 demonstrated that it was most likely that the variation in the pattern of global interference was determined by the variable of eccentricity, rather than by the sizes of the global and local levels.     

Creating a sustainable global society— the evolutionary path

Many indicators suggest that modern society is presently in a period of transition. The older order is showing obvious signs of decline, and elements of a new order appear to be forming. Growing numbers of people are coming to recognize that the worsening global dilemmas are best viewed as symptoms of an underlying disorder involving some of the most deeply underlying assumptions of modern society. The ultimate resolution of these dilemmas will come about, not through politically implemented “solutions,” but through our further evolution to a fundamentally different, “trans‐modern” society. The key challenge to individuals and organizations is to understand the necessary evolutionary change well enough to contribute toward its taking place with a minimum of attendant social disruption and human misery.     

Thinking ethically about the global in ‘Global Ethics’

In what follows, I claim that the ‘global’ in ‘Global Ethics’ needs also to be thought about in a different way, not as the scope or object of ethical judgement but in relation to the worlds reproduced by the practice of ethical judgement itself. In summary, ethical reflection on the meaning of the ‘global’ in the practice of Global Ethics as a field of academic inquiry is what is required if the future of Global Ethics is to be something other than Ethics or Applied Ethics as traditionally conducted.     

Do McCollough effects provide evidence for global pattern processing?

Contingent color aftereffects (CAEs, or McCollough effects) were induced using two pairs of orthogonally related patterns (horizontal/vertical and concentric/radial) to determine whether the CAEs of the four patterns are independent. Tests using composite test patterns (like those employed by Emerson, Humphrey, & Dodwell, 1985) suggested independent aftereffects. However, tests using unitary patterns indicated additive or competing effects of the four patterns in regions where line orientations were similar, and tests isolating such regions showed clear interactions between the pattern aftereffects. The results fail to support the claim that global (rather than local) features of the patterns control these CAEs.     

Disaggregated pluralistic theories of global distributive justice – a critique

Pluralistic theories of global distributive justice aim at justifying a plurality of principles for various subglobal contexts of distributive justice. Helena de Bres has recently proposed the class of disaggregated pluralistic theories, according to which we should refrain from defending principles that apply to the shared background conditions of such subglobal contexts. This article argues that if one does not justify how these background conditions should be regulated by principles of a just global basic structure, then the (apparent) realization of the principles that are justified for the subglobal contexts of distributive justice can erode and undermine justice over time. For example, the realization of justice in international trade might undermine climate justice, at least if climate justice requires increasing tariffs (in order to mitigate greenhouse gas emissions) but justice in international trade calls for reducing tariffs (in order to create a level playing field). Principles of a just global basic structure would have to ensure that such justice-eroding spillover effects from one to another context of justice do not occur. Finally, the article responds critically to de Bres’ objections that an account of a just global basic structure is too idealistic, not action guiding, and superfluous.     

Beyond Christendom: Protestant—Catholic distinctions in coming global Christianity

Using actual and projected population data from the World Christian Database, this article evaluates Philip Jenkins' argument that the centre of global Christianity is moving from the Euro‐American centre (the ‘global North’) to the developing world (the ‘global South’) by disaggregating the different outcomes of this shift for Protestants and Catholics. Over the next fifty years, Catholics will decline much less than Protestants in the North, and will be concentrated in Latin America, not Africa. With the decline of the Enlightenment nation‐state, religious authority and identity will become more concentrated in Catholicism but will become more dispersed in Protestantism. This transition from national to global Christianity, I argue, will realign the post‐Reformation achievement of balanced tension among three social realitiesd Protestantism, Catholicism and the nation‐statedto produce not just another Christendom but a new, more complex articulation of civil and religious realities that will move beyond the old arrangement of Christendom altogether.     

Motion capture by a frame: global or local processing?

The possibility that frames serve to capture lines within them so that they appear on a coplanar surface was investigated, using coherence in direction of rotary motion (Gillam, 1972) as a quantitative measure of the coplanarity of frame and internal lines. It was found that perceptual coherence between a pair of lines was greatly increased by surrounding them with a frame, if the frame was perspectivally consistent with the lines. A second experiment showed that this grouping can be attributed to a global effect of the frame and cannot be accounted for by local grouping of the internal lines with components of the frame.     

Preserved visual lexicosemantics in global aphasia: a right-hemisphere contribution?

Extensive testing of a patient, GP, who encountered large-scale destruction of left-hemisphere (LH) language regions was undertaken in order to address several issues concerning the ability of nonperisylvian areas to extract meaning from printed words. Testing revealed recognition of superordinate boundaries of animals, tools, vegetables, fruit, clothes, and furniture. GP was able to distinguish proper names from other nouns and from nonwords. GP was also able to differentiate words representing living things from those denoting nonliving things. The extent of LH infarct resulting in a global impairment to phonological and syntactic processing suggests LH specificity for these functions but considerable right-hemisphere (RH) participation in visual lexicosemantic processing. The relative preservation of visual lexicosemantic abilities despite severe impairment to all aspects of phonological coding demonstrates the importance of the direct route to the meaning of single printed words.     

Normal McCollough effect in Alzheimer’s disease and global amnesia

The McCollough effect (ME), a long-lasting, pattern-contingent aftereffect in normal human vision, was examined in persons with known deficits in memory. We induced MEs in 11 subjects, 5 patients with various severities of Alzheimer’s disease (AD), H.M. (a patient who has global amnesia due to bilateral medial temporal lobectomy and who has been studied for 35 years since his operation), and 5 control subjects. H.M. and the AD patients showed MEs of strength and duration comparable to those of the control subjects. These results demonstrate a dissociation between learning mechanisms that mediate recall and recognition versus mechanisms that mediate the ME. Furthermore, knowledge about the sites of neuropathology in H.M. and in AD are consistent with other sources of evidence implicating early visual areas, especially V1, as a critical locus of the ME.     

A global factor in the Hermann grid illusion or an artifact?

In the first of the present experiments, subjects were required to estimate the strength of the Hermann grid illusion in grids containing various numbers of intersectionseven though those grids were not actually presented. The positive relationship found by Wolfe (1984) for real grids was, nevertheless, replicated. It is argued that this suggests that a response bias might have been the source of his effect (although other possibilities are also noted). In addition, in a second experiment, subjects who were not aware of the fact that grid size was being manipulated (i.e., between subjects) showed no consistent effect of that factor, thus supporting the same suggestion.     

Openness to experience and creativity: When does global citizenship matter?

The relationship between the openness to experience trait (OTE) and creativity has been well documented in previous research. Likewise, the global citizenship construct has theoretical overlap with both OTE and creativity. We hypothesised global citizenship would make a unique contribution to explaining variance in five types of creativity (self/everyday, scholarly, performance, mechanical/scientific and artistic), above and beyond the contribution of OTE. Participants were predominantly female, European American, traditionally aged college students (N = 407). Global citizenship prosocial outcomes explained unique variance in self/everyday (sr² = .10), scholarly (sr² = .03) and mechanical/scientific (sr² = .03) creativity. Results are discussed in terms of dual processes theories of cognition.
