Human rights treaties are often attached and complemented with Optional Protocols. The Optional protocol instruments are adopted after careful deliberation between different stakeholders including member states to human rights treaties. -/- The present document on Introduction to the International Covenant on Economic Social and Cultural Rights- Optional Protocol [OP-ICESCR] is an addition to the on-going work on the Human Rights Framework on ESC Rights. It covers basic information on the objectives of the OP and the key provisions dealing with the (...) redressal mechanisms and processes. Much emphasis is given to highlighting the expansion of the normative framework through the works of the Committee under the ICESCR. The document highlights a few of the important standards developed, interpreted and applied by the Committee in its dealing with member states. The document also mentions a few areas that need further study and analysis in order to understand the impact of the OP-ICESCR mechanisms within domestic jurisdictions, particularly of the member states.

In Knowledge and Its Limits Timothy Williamson argues against the luminosity of phenomenal states in general by way of arguing against the luminosity of feeling cold, that is, against the view that if one feels cold, one is at least in a position to know that one does. In this paper I consider four strategies that emerge from his discussion, and argue that none succeeds.

In his influential paper 'Speaker's Reference and Semantic Reference', Kripke defends Russell's theory of descriptions against the charge that the existence of referential and attributive uses of descriptions reflects a semantic ambiguity. He presents a purely defensive argument to show that Russell's theory is not refuted by the referential usage and a number of methodological considerations which apparently tell in favour of Russell's unitary theory over an ambiguity theory. In this paper, I put forward a case for the ambiguity theory (...) that thwarts Kripke's defensive strategy and argue that it is not undermined by any of his methodological points. (shrink)

We present a theory of human artistic experience and the neural mechanisms that mediate it. Any theory of art has to ideally have three components. The logic of art: whether there are universal rules or principles; The evolutionary rationale: why did these rules evolve and why do they have the form that they do; What is the brain circuitry involved? Our paper begins with a quest for artistic universals and proposes a list of ‘Eight laws of artistic experience’ -- a (...) set of heuristics that artists either consciously or unconsciously deploy to optimally titillate the visual areas of the brain. One of these principles is a psychological phenomenon called the peak shift effect: If a rat is rewarded for discriminating a rectangle from a square, it will respond even more vigorously to a rectangle that is longer and skinnier that the prototype. We suggest that this principle explains not only caricatures, but many other aspects of art. Example: An evocative sketch of a female nude may be one which selectively accentuates those feminine form-attributes that allow one to discriminate it from a male figure; a Boucher, a Van Gogh, or a Monet may be a caricature in ‘colour space’ rather than form space. Even abstract art may employ ‘supernormal’ stimuli to excite form areas in the brain more strongly than natural stimuli. Second, we suggest that grouping is a very basic principle. The different extrastriate visual areas may have evolved specifically to extract correlations in different domains , and discovering and linking multiple features into unitary clusters -- objects -- is facilitated and reinforced by direct connections from these areas to limbic structures. In general, when object-like entities are partially discerned at any stage in the visual hierarchy, messages are sent back to earlier stages to alert them to certain locations or features in order to look for additional evidence for the object . Finally, given constraints on allocation of attentional resources, art is most appealing if it produces heightened activity in a single dimension rather than redundant activation of multiple modules. This idea may help explain the effectiveness of outline drawings and sketches, the savant syndrome in autists, and the sudden emergence of artistic talent in fronto-temporal dementia. In addition to these three basic principles we propose five others, constituting a total of ‘eight laws of aesthetic experience’. (shrink)

(1) The induced colours led to perceptual grouping and pop-out, (2) a grapheme rendered invisible through ‘crowding’ or lateral masking induced synaesthetic colours — a form of blindsight — and (3) peripherally presented graphemes did not induce colours even when they were clearly visible. Taken collectively, these and other experiments prove conclusively that synaesthesia is a genuine percep- tual phenomenon, not an effect based on memory associations from childhood or on vague metaphorical speech. We identify different subtypes of number–colour synaesthesia (...) and propose that they are caused by hyperconnectivity between col- our and number areas at different stages in processing; lower synaesthetes may have cross-wiring (or cross-activation) within the fusiform gyrus, whereas higher synaesthetes may have cross-activation in the angular gyrus. This hyperconnec- tivity might be caused by a genetic mutation that causes defective pruning of con- nections between brain maps. The mutation may further be expressed selectively (due to transcription factors) in the fusiform or angular gyri, and this may explain the existence of different forms of synaesthesia. If expressed very diffusely, there may be extensive cross-wiring between brain regions that represent abstract concepts, which would explain the link between creativity, metaphor and synaesthesia (and the higher incidence of synaesthesia among artists and poets). Also, hyperconnectivity between the sensory cortex and amygdala would explain the heightened aversion synaesthetes experience when seeing numbers printed in the ‘wrong’ colour. Lastly, kindling (induced hyperconnectivity in the temporal lobes of temporal lobe epilepsy [TLE] patients) may explain the purported higher incidence of synaesthesia in these patients. We conclude with a synaesthesia-based theory. (shrink)

Although a number of studies have demonstrated that perceived ethical leadership engenders beneficial follower outcomes, there is a dearth of research on ethical leadership in the sales context. This is surprising given that salespersons constantly face ethical challenges in their work environment and ethical leadership could provide them with appropriate guidelines for navigating such challenges successfully. Focusing on the salesperson’s perspective and responding to calls for investigating underlying processes responsible for the effects of ethical leadership, this study proposes that sales (...) managers’ ethical leadership influences salespersons’ emulation intentions—i.e., their intentions to model or imitate the manager’s ethical behavior—which, in turn, influences both behavior and outcome performance. In addition, salespersons’ perceptions of the manager’s competence and gratitude toward the manager are examined as moderating mechanisms on the relationship between ethical leadership and salespersons’ emulation. Finally, three aspects of the ethical climate prevailing in the organization—ethical responsibility, peers’ unethical behavior, and unethical sales practices—are included as control variables. The proposed relationships are tested by using data from 290 business-to-business salespeople. Based on the findings, implications are offered for theory and practice. (shrink)

Murali Ramachandran has kindly provided me with four (alleged) counterexamples to the theory of causation which I recently put forward in Mind (Ramachandran 2000; Noordhof 1999).

I will also presume knowledge of the framework of my paper and just give page references in case this is helpful. (...) I will try to couch the discussion with as little reference to the technical apparatus of my paper as possible. Maybe the ideas will stand out more clearly that way. (shrink)

Subjects perceived touch sensations as arising from a table (or a rubber hand) when both the table (or the rubber hand) and their own real hand were repeatedly tapped and stroked in synchrony with the real hand hidden from view. If the table or rubber hand was then ‘injured’, subjects displayed a strong skin conductance response (SCR) even though nothing was done to the real hand. Sensations could even be projected to anatomically impossible locations. The illusion was much less vivid, (...) as indicated by subjective reports and SCR, if the real hand was simultaneously visible during stroking, or if the real hand was hidden but touched asynchronously. The fact that the illusion could be significantly diminished when the real hand was simultaneously visible suggests that the illusion and associated SCRs were due to perceptual assimilation of the table (or rubber hand) into one’s body image rather than associative conditioning. These experiments demonstrate the malleability of body image and the brain’s remarkable capacity for detecting statistical correlations in the sensory input. (shrink)

This article supplements our earlier paper on synaesthesia published in JCS (Ramachandran & Hubbard, 2001a). We discuss the phenomenology of synaesthesia in greater detail, raise several new questions that have emerged from recent studies, and suggest some tentative answers to these questions.

There are currently two main philosophical theories of perception - Direct Realism and the Representative Theory. The former is supported by most contemporary philosophers, whereas the latter forms the groundwork for most scientific theories in this area. The paper describes a recent experiment involving retinal and cortical rivalry that provides strong empirical evidence that the Direct Realist theory is incorrect. There are of course a large number of related experiments on visual perception that would tend to lead us to the (...) same conclusion, but the experiment described in this paper does so in a singularly direct and straightforward manner. Often the most telling experiments are the simplest. (shrink)

Family firm philanthropy is the donation of resources to support societal betterment in ways meaningful for the controlling family. Family business literature suggests that socioemotional goals of achieving family prominence, harmony, and continuity drive FFP. However, these drivers fail to explain spiritually motivated philanthropic behaviors like anonymous giving by business families. 14 case studies of Indian Hindu business families with a combined FFP exceeding 2 billion INR in 2016–17 reveal spirituality or the moral dimension as an additional important driver of (...) corporate behaviors like FFP. Two fundamental spiritual beliefs of _dharma_ and _karma_ instill a duty-bound giving culture in Hindus. However, the strength of each belief varies in controlling families revealing four configurations of philanthropists labeled as _Devout_, _Committed_, _Devoid_, and _Coerced_ in this study. _Devouts_, the biggest givers, are spiritually motivated, controlled by at least third-generation family members with executive power and professional support. _Committed_ philanthropists are motivated by societal development rather than spirituality. While _devoids_ hold spiritual beliefs, they neglect to devote appropriate resources or develop professional structures to support FFP. _Coerced_, the smallest givers, focus on business growth, lack family champions or supporting professional structures, and face turbulent family or business domains.

The mechanism by which humans perceive others differs greatly from how humans perceive inanimate objects. Unlike inanimate objects, humans have the distinct property of being “like me” in the eyes of the observer. This allows us to use the same systems that process knowledge about self-performed actions, self-conceived thoughts, and self-experienced emotions to understand actions, thoughts, and emotions in others. The authors propose that internal simulation mechanisms, such as the mirror neuron system, are necessary for normal development of recognition, imitation, (...) theory of mind, empathy, and language. Additionally, the authors suggest that dysfunctional simulation mechanisms may underlie the social and communicative deficits seen in individuals with autism spectrum disorders. (shrink)

We studied two otherwise normal, synaesthetic subjects who `saw' a speci¢c colour every time they saw a speci¢c number or letter. We conducted four experiments in order to show that this was a genuine perceptual experience rather than merely a memory association. (i)The synaesthetically induced colours could lead to perceptual grouping, even though the inducing numerals or letters did not. (ii)Synaesthetically induced colours were not experienced if the graphemes were presented peripherally. (iii)Roman numerals were ine¡ective: the actual number grapheme was (...) required. (iv)If two graphemes were alternated the induced colours were also seen in alternation. However, colours were no longer experienced if the graphemes were alternated at more than 4 Hz. We propose that grapheme colour synaesthesia arises from `cross-wiring' between the `colour centre' (area V4 or V8)and the `number area', both of which lie in the fusiform gyrus. We also suggest a similar explanation for the representation of metaphors in the brain: hence, the higher incidence of synaesthesia among artists and poets. (shrink)

Neurological syndromes in which consciousness seems to malfunction, such as temporal lobe epilepsy, visual scotomas, Charles Bonnet syndrome, and synesthesia offer valuable clues about the normal functions of consciousness and ‘qualia’. An investigation into these syndromes reveals, we argue, that qualia are different from other brain states in that they possess three functional characteristics, which we state in the form of ‘three laws of qualia’. First, they are irrevocable: I cannot simply decide to start seeing the sunset as green, or (...) feel pain as if it were an itch; second, qualia do not always produce the same behaviour: given a set of qualia, we can choose from a potentially infinite set of possible behaviours to execute; and third, qualia endure in short-term memory, as opposed to non-conscious brain states involved in the on-line guidance of behaviour in real time. We suggest that qualia have evolved these and other attributes because of their role in facilitating non-automatic, decision-based action. We also suggest that the apparent epistemic barrier to knowing what qualia another person is experiencing can be overcome by using a ‘bridge’ of neurons; and we offer a hypothesis about the relation between qualia and one's sense of self.

Patients with right parietal lesions often deny their paralysis , but do they have "tacit" knowledge of their paralysis? I devised three novel tests to explore this. First, the patients were given a choice between a bimanual task vs a unimanual one . They chose the former on 17 of 18 trials and, surprisingly, showed no frustration or learning despite repeated failed attempts. I conclude that they have no tacit knowledge of paralysis . Second, I used a "virtual reality box" (...) to convey the optical illusion to the patient that she was moving her paralyzed left hand up and down to the rhythm of a metronome, and yet she showed no sign of surprise. Third, I irrigated patient BM′s left ear canal with cold water, a procedure that is known to shift that patient′s spatial frame of reference by stimulating the vestibular system. Surprisingly, this allowed her "repressed" memory of paralysis to come to the surface; she said she had been paralyzed continuously for several days. I suggest that the vestibular stimulation produces these remarkable effects by mimicking REM sleep. These patients also emply a whole arsenal of grossly exaggerated Freudian "defense mechanisms" to account for their paralysis. To explain this, I propose that in normal individuals the left hemisphere ordinarily deals with small, local anomalies by trying to impose consistency but, when the anomaly exceeds threshold, an interaction with the right hemisphere forces a "paradigm shift". A failure of this process, in patients with right hemisphere damage, might partially account for anosognosia. Finally, I present a new conceptual framework that may help link several psychological and neurological phenomena such as Freudian defense mechanisms, vestibular stimulation, anosognosia, memory repression, visual illusions, anterograde amnesia, REM sleep, dreaming, and humor.

On David Lewis's original analysis of causation, c causes e only if c is linked to e by a chain of distinct events such that each event in the chain (counter-factually) depends on the former one. But this requirement precludes the possibility of late pre-emptive causation, of causation by fragile events, and of indeterministic causation. Lewis proposes three different strategies for accommodating these three kinds of cases, but none of these turn out to be satisfactory. I offer a single analysis (...) of causation that resolves these problems in one go but which respects Lewis's initial insights. One distinctive feature of my account is that it accommodates indeterministic causation without resorting to probabilities. (shrink)

David Lewis modified his original theory of causation in response to the problem of ‘late preemption’ (see 1973b; 1986b: 193-212). However, as we will see, there is a crucial difference between genuine and preempted causes that Lewis must appeal to if his solution is to work. We argue that once this difference is recognized, an altogether better solution to the preemption problem presents itself.

The emancipation of women has become a strong critical discourse in Bengali literature since the 19th century. Only since the second half of the 20th century, however, have female writers markedly stepped out of the shadow of their male colleagues, and the writings on women become more and more often articulated by women themselves. In this article, I focus on particular concepts of femininity in selected texts of two outstanding writers of different generations, a prose writer, and a woman poet: (...) Mahasweta Debi (b. 1926) and Mallika Sengupta (1960–2011). Analyzing Mahasweta’s female characters, I focus on the issue of the double marginalization of dalit tribal women; we can find here impacts of intersectional discrimination of class, gender and caste. Debi is very radical in her social criticism but is quite reluctant to accept the label of feminism. Mallika, on the other hand, represents a movement among the female writers of her generation that openly declares her support for feminist ideologies, which can be demonstrated on some of the examples referred to here. Another important strand of Mallika’s constructions of femininity are archetypal images — mythological metaphors of femininity (in the Hindu context) which may in some cases be interpreted in accordance with difference feminism, in others as a critique of the essentialized and dichotomous concepts of masculinity and femininity. While Mahasweta’s emancipation drive is more deeply grounded in her field research and journalistic activism in the tribal areas she writes about, Mallika’s has been more strongly linked with the academia and has joined the theoretical feminist discourse. Through a close reading the women’s emancipation discourse of these two protagonists in Bengali literature, we can speak of a shift from a practical, concrete criticism, to a theoretically founded radicalism.

[opening paragraph]: Ramachandran and Hirstein in their article, ‘The Science of Art: A Neurological Theory of Aesthetic Experience’ make the grandiose claim of having developed a theory of human aesthetic experience, while reducing that very experience to meaningless terms. As a practising artist whose work is informed by contemporary theory as well as a Buddhist practice, I find it hard to take their argument seriously. Clearly, it is necessary to examine one's assumptions about the nature of the artistic experience (...) before attempting to develop grand theory. (shrink)

Summary Apotemnophilia, or body integrity image disorder (BIID), is characterised by a feeling of mismatch between the internal feeling of how one’s body should be and the physical reality of how it actually is. Patients with this condition have an often overwhelming desire for an amputation- of a specific limb at a specific level. Such patients are not psychotic or delusional, however, they do express an inexplicable emotional abhorrence to the limb they wish removed. It is also known that such (...) patients show a left-sided preponderance for their desired amputation. Often they take drastic action to be rid of the offending limb. Given the left-sided bias, emotional rejection and specificity of desired amputation, we suggest that there are clear similarities to be drawn between BIID and somatoparaphrenia. In this rare condition, which follows a right parietal stroke, the patient rejects (usually) his left arm as ‘‘alien’’. We go on to hypothesis that a dysfunction of the right parietal lobe is also the cause of BIID. We suggest that this leads to an uncoupling of the construct of one’s body image in the right parietal lobe from how one’s body physically is. This hypothesis would be amenable to testing by response to cold-water vestibular caloric stimulation, which is known to temporarily treat somatoparaphrenia. It could also be investigated using functional brain imaging and skin conductance response. If correct our hypothesis not only suggests why BIID arises, but also, in caloric stimulation a therapeutic avenue for this chronic and essentially untreatable condition. (shrink)

André Gallois (1998) attempts to defend the occasional identity thesis (OIT), the thesis that objects which are distinct at one time may nonetheless be identical at another time, in the face of two influential lines of argument against it. One argument involves Kripke’s (1971) notion of rigid designation and the other, Leibniz’s law (affirming the indiscernibility of identicals). It is reasonable for advocates of (OIT) to question the picture of rigid designation and the version of Leibniz’s law that these arguments (...) employ, but, the problem is, some form of rigidity is required for one to affirm the occasional identity of objects, and some (restricted) version of Leibniz’s law must be conceded if identity really is involved. Gallois accordingly recommends an account of rigidity and a version of Leibniz’s law to this end.1 We find Gallois’ proposals entirely inadequate to their task. We aim in this paper is to explicate and defend an alternative approach for occasional identity theorists. We do not seek to defend (OIT) per se; our aim, rather, is simply to show that the arguments from rigid designation and Leibniz’s law are inconclusive. Let’s begin with an outline of these arguments.

An interview with Anthony Freeman, in which one of the original authors of ‘The Science of Art’ [JCS, 6, No. 6/7, 1999] responds to to ongoing commentary.

Here we outline a simple method of using two mirrors which allows one to stand outside oneself. This method demonstrates that registration of vision with touch and proprioception is crucial for the perception of the corporeal self. Our method may also allow the disassociation of taste from touch, proprioception, and movement.

The leading idea of this article is that one cannot acquire knowledge of any non-epistemic fact by virtue of knowing that one that knows something. The lines of reasoning involved in the surprise exam paradox and in Williamson’s _reductio_ of the KK-principle, which demand that one can, are thereby undermined, and new type of counter-example to epistemic closure emerges.

Music plagiarism is defined as using tune, or melody that would closely imitate with another author’s music without proper attributions. It may occur either by stealing a musical idea or sampling. Unlike the traditional music, the Indian cinematic music is extremely popular amongst the public. Since the expectations of the public for songs that are enjoyable are high, many music directors are seeking elsewhere to “borrow” tunes. Whilst a vast majority of Indian cinemagoers may not have noticed these plagiarised tunes, (...) some journalists and vigilant music lovers have noticed these activities. This study has taken the initiative to investigate the extent of plagiaristic activities within one Indian cinematic music industry. A list of plagiarised songs was produced by using YouTube® searches for “comparative videos” made by the vigilant music lovers about accused/detected music plagiarism. Some of these individuals were also interviewed to understand their views on this. During the investigation, it was possible to identify a vast number of plagiarised tunes, snippets, or even the full songs. In fact, some of these examples’ dates to 1954, during the era when no one would have noticed plagiarism. The paper would highlight the similarities of these music files. It will also show some examples of the excuses/denial given by the composers and would try to highlight the attitudes of general public towards these types of activities. (shrink)

Several recent lines of inquiry have pointed to the amygdala as a potential lesion site in autism. Because one function of the amygdala may be to produce autonomic arousal at the sight of a significant face, we compared the responses of autistic children to their mothers’ face and to a plain paper cup. Unlike normals, the autistic children as a whole did not show a larger response to the person than to the cup. We also monitored sympathetic activity in autistic (...) children as they engaged in a wide range of everyday behaviours. The children tended to use self-stimulation activities in order to calm hyper-responsive activity of the sympathetic (`fight or flight’) branch of the autonomic nervous system. A small percentage of our autistic subjects had hyporesponsive sympathetic activity, with essentially no electrodermal responses except to self-injurious behaviour. We sketch a hypothesis about autism according to which autistic children use overt behaviour in order to control a malfunctioning autonomic nervous system and suggest that they have learned to avoid using certain processing areas in the temporal lobes.

Hempel‘s paradox of the ravens, and his take on it, are meant to be understood as being restricted to situations where we have no additional background information. According to him, in the absence of any such information, observations of FGs confirm the hypothesis that all Fs are G. In this paper I argue against this principle by way of considering two other paradoxes of confirmation, Goodman‘s 'grue‘ paradox and the 'tacking‘ (or 'irrelevant conjunct‘) paradox. What these paradoxes reveal, I argue, (...) is that a presumption of causal realism is required to ground any confirmation; but once we grant causal realism, we have no reason to accept the central principles giving rise to the paradoxes.
