Extraversion has two central characteristics: (1) interpersonalengagement, which consists of affiliation (enjoying and valuing close interpersonal bonds, being warm and affectionate) and agency (being socially dominant, enjoying leadership roles, being assertive, being exhibitionistic, and having a sense of potency in accomplishing goals) and (2) impulsivity, which emerges from the interaction of extraversion and a second, independent trait (constraint). Agency is a more general motivational disposition that includes dominance, ambition, mastery, efficacy, and achievement. Positive affect (a combination of positive feelings and (...) motivation) is closely associated with extraversion. Extraversion is accordingly based on positiveincentivemotivation. (shrink)

The commentaries on our target article address three main areas: (1) the relative importance of extraversion and other related traits to DA functioning, (2) how the long-term stability of extraversion can be conceptualized within a highly plastic central nervous system, and (3) the nature of DA functioning in the MOC network and in extraversion. We have organized our Response, therefore, into three major sections.

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Technological innovations such as next generation sequencing and DNA hybridisation enrichment have resulted in multi‐fold increases in both the quantity of ancient DNA sequence data and the time depth for DNA retrieval. To date, over 30 ancient genomes have been sequenced, moving from 0.7× coverage (mammoth) in 2008 to more than 50× coverage (Neanderthal) in 2014. Studies of rapid evolutionary changes, such as the evolution and spread of pathogens and the genetic responses of hosts, or the genetics of domestication and (...) climatic adaptation, are developing swiftly and the importance of palaeogenomics for investigating evolutionary processes during the last million years is likely to increase considerably. However, these new datasets require new methods of data processing and analysis, as well as conceptual changes in interpreting the results. In this review we highlight important areas of future technical and conceptual progress and discuss research topics in the rapidly growing field of palaeogenomics. -/- . (shrink)

Previous research has suggested that in cultural production fields the concatenation of eminence explains success, defined as influence and innovation. We propose that individuals in fields as diverse as philosophy, literature, mathematics, painting, or architecture gain visibility by cumulating the eminence of others connected to them across and within generations. We draw on interaction ritual chain and social movement theories, and use evidence from the field of modernist architecture, to formulate a model of how networks of very strong ties generate (...) motivations and emotional enthusiasm, change reputations, and form collective movements that over time transform the structure of cultural fields. Because major aesthetic innovations break sharply with older styles, they need very strong group solidarity over a long period of time to propagate a new standard of practice. We propose mutual halo effects, i.e., the reciprocal reinforcement of upstream and downstream prestige on a given individual node, as the key factor accounting for success in a cultural production field. We discuss the relevance of these results for building a model of influence and innovation in cultural production fields in which networks—reshaped by shifting technological, political, and economic conditions—trigger new styles.

Metabolic pathways underlying brain function remain largely unexplored during neurodevelopment, predominantly due to the lack of feasible techniques for use with awake infants. Broadband near-infrared spectroscopy provides the opportunity to explore the relationship between cerebral energy metabolism and blood oxygenation/haemodynamics through the measurement of changes in the oxidation state of mitochondrial respiratory chain enzyme cytochrome-c-oxidase alongside haemodynamic changes. We used a bNIRS system to measure ΔoxCCO and haemodynamics during functional activation in a group of 42 typically developing infants aged between (...) 4 and 7 months. bNIRS measurements were made over the right hemisphere over temporal, parietal and central cortical regions, in response to social and non-social visual and auditory stimuli. Both ΔoxCCO and Δ[HbO2] displayed larger activation for the social condition in comparison to the non-social condition. Integration of haemodynamic and metabolic signals revealed networks of stimulus-selective cortical regions that were not apparent from analysis of the individual bNIRS signals. These results provide the first spatially resolved measures of cerebral metabolic activity alongside haemodynamics during functional activation in infants. Measuring synchronised changes in metabolism and haemodynamics have the potential for uncovering the development of cortical specialisation in early infancy. (shrink)

The use of upper limb vibration during exercise and rehabilitation continues to gain popularity as a modality to improve function and performance. Currently, a lack of knowledge of the pathways being altered during ULV limits its effective implementation. Therefore, the aim of this study was to investigate whether indirect ULV modulates transmission along spinal and corticospinal pathways that control the human forearm. All measures were assessed under CONTROL and ULV conditions while participants maintained a small contraction of the right flexor (...) carpi radialis muscle. To assess spinal pathways, Hoffmann reflexes elicited by stimulation of the median nerve were recorded from FCR with motor response amplitudes matched between conditions. An H-reflex conditioning paradigm was also used to assess changes in presynaptic inhibition by stimulating the superficial radial nerve 37 ms prior to median nerve stimulation. Cutaneous reflexes in FCR elicited by stimulation of the SR nerve at the wrist were also recorded. To assess corticospinal pathways, motor evoked potentials elicited by transcranial magnetic stimulation of the contralateral motor cortex were recorded from the right FCR and biceps brachii. ULV significantly reduced H-reflex amplitude by 15.7% for both conditioned and unconditioned reflexes. Therefore, ULV inhibits cutaneous and H-reflex transmission without influencing corticospinal excitability of the forearm flexors suggesting increased presynaptic inhibition of afferent transmission as a likely mechanism. A general increase in inhibition of spinal pathways with ULV may have important implications for improving rehabilitation for individuals with spasticity. (shrink)

I defend a theory of mental representation that satisfies naturalistic constraints. Briefly, we begin by distinguishing (i) what makes something a representation from (ii) given that a thing is a representation, what determines what it represents. Representations are states of biological organisms, so we should expect a unified theoretical framework for explaining both what it is to be a representation as well as what it is to be a heart or a kidney. I follow Millikan in explaining (i) in terms (...) of teleofunction, explicated in terms of natural selection. -/- To explain (ii), we begin by recognizing that representational states do not have content, that is, they are neither true nor false except insofar as they both “point to” or “refer” to something, as well as “say” something regarding whatever it is they are about. To distinguish veridical from false representations, there must be a way for these separate aspects to come apart; hence, we explain (ii) by providing independent theories of what I call f-reference and f-predication (the ‘f’ simply connotes ‘fundamental’, to distinguish these things from their natural language counterparts). -/- Causal theories of representation typically founder on error, or on what Fodor has called the disjunction problem. Resemblance or isomorphism theories typically founder on what I’ve called the non-uniqueness problem, which is that isomorphisms and resemblance are practically unconstrained and so representational content cannot be uniquely determined. These traditional problems provide the motivation for my theory, the structural preservation theory, as follows. F-reference, like reference, is a specific, asymmetric relation, as is causation. F-predication, like predication, is a non-specific relation, as predicates typically apply to many things, just as many relational systems can be isomorphic to any given relational system. Putting these observations together, a promising strategy is to explain f-reference via causal history and f-predication via something like isomorphism between relational systems. -/- This dissertation should be conceptualized as having three parts. After motivating and characterizing the problem in chapter 1, the first part is the negative project, where I review and critique Dretske’s, Fodor’s, and Millikan’s theories in chapters 2-4. Second, I construct my theory about the nature of representation in chapter 5 and defend it from objections in chapter 6. In chapters 7-8, which constitute the third and final part, I address the question of how representation is implemented in biological systems. In chapter 7 I argue that single-cell intracortical recordings taken from awake Macaque monkeys performing a cognitive task provide empirical evidence for structural preservation theory, and in chapter 8 I use the empirical results to illustrate, clarify, and refine the theory.

My paper defends the use of the poverty of stimulus argument (POSA) for linguistic nativism against Cowie's (1999) counter-claim that it leaves empiricism untouched. I first present the linguistic POSA as arising from a reflection on the generality of the child's initial state in comparison with the specific complexity of its final state. I then show that Cowie misconstrues the POSA as a direct argument about the character of the pld. In this light, I first argue that the data Cowie (...) marshals about the pld does not begin to suggest that the POSA is unsound. Second, through a discussion of the so-called `auxiliary inversion rule', I show, by way of diagnosis, that Cowie misunderstands both the methodology of current linguistics and the complexity of the data it is obliged to explain.

Did the September 11, 2001 terrorist attacks on the U.S. cause the values of teenagers in the U.S. to change? Did their previously important self-esteem and self-actualization values become less important and their survival and safety values become more important? Changes in the values of teenagers are important for practitioners, managers, marketers, and researchers to understand because high school students are our current and future employees, managers, and customers, and research has shown that values impact work and consumer-related attitudes and (...) behaviors. Further, studies that compared higher to lower performing for-profit and not-for-profit companies have found that higher performing organizations had strong values that permeated their organizations [Collins J. C., and J. I. Porras: 1994, Built to Last: Successful Habits of Visionary Companies (New York, Harper Business); O’Reilly, C. A. and J. A. Chatman: 1996, in B. M. Staw and L. L.

San Francisco, Jossey Bass)]. While one study of adults found value changes, no known studies have explored if the values of teenagers also changed post-9/11. This study filled that research gap by exploring the values of a random sample of 1000 U.S. teenagers in grades 9 to 12 pre- and post-9/11, using a demographic questionnaire and the Rokeach Value Survey. The research results indicated that teenage survival, safety, and security values (a world at peace, freedom, national security, and salvation) increased in importance while their self-esteem and self-actualization values (a sense of accomplishment, inner harmony, pleasure, self-respect, and wisdom) decreased in importance, mirroring the changes for adults. The meaning of these findings for practitioners, managers, marketers and researchers was discussed. (shrink)

We examine the relationships among religious governance, especially Islamic governance quality (IGQ), national governance quality (NGQ), and risk management and disclosure practices (RDPs), and consequently ascertain whether NGQ has a moderating influence on the IGQ–RDPs nexus. Using one of the largest data sets relating to Islamic banks from 10 Middle East and North Africa (MENA) countries from 2006 to 2013, our findings are threefold. First, we find that RDPs are higher in banks with higher IGQ. Second, we find that RDPs (...) are higher in banks from countries with higher NGQ. Finally, we find that NGQ has a moderating effect on the IGQ–RDPs nexus. Our findings are robust to alternative RDP measures and estimation techniques. These results imply that the quality of disclosure depends on the nature of the macro-social-level factors, such as religion that have remained largely unexplored in business and society research, and, therefore, have important implications for policy makers.

In lieu of an abstract, here is a brief excerpt of the content:Rushdie’s Dastan-e-Dilruba: The Satanic Verses As Rushdie’s Love Letter to IslamFeroza Jussawalla (bio)Meheruban likhoon ya dilruba likhoon hyran hoon ke apke khat me kya likhoonYe mera prempatr padh kar ke tum naraz na hona ke tum meri zindagi ho ke tum meri bandagi ho[Should I address you as respected one Should I address you as beloved one I am so distraught about how I should address youWhen you read (...) my love letter You should not be disappointed Because you are my life and you are my “life’s work”]—Popular Hindi film song from Raj Kapoor’s Sangam (1964) [my translation]Salman Rushdie has been classified as a postcolonial 1 writer whose fiction depicts the hybrid nature of postcolonials in their migrations and movements, their merging and mixing. Rushdie has variously been called a “Third World Cosmopolitan” [Brennan, Salman Rushdie viii], a “metropolitan intellectual,” and “a hybrid” but most often a [End Page 50] “postcolonial,” because of his “birth” as a “Midnight’s child”—a child born as India was gaining independence at midnight on 14 August 1947 2 —his subsequent education in England, and the making of his home in metropolitan London. Such a perspective is eurocentric and does not provide complete answers to Rushdie’s complex works or the complicated response to his work. For the very hybridity that Rushdie manifests results from his being not only a “post-British” colonial but also a “post-Mughal” colonial.The British were not the only colonizers of India. In fact, Indian historians have traditionally identified several waves of colonization. Journalists Larry Collins and Dominique Lapierre best summarize the two major waves of colonization as follows:Hinduism itself had been brought to India by the Indo-European hordes descending from the North to wrest the subcontinent from its ancient Dravidian inhabitants.... The faith of the Prophet had come much later, after the cohorts of Genghis Khan and Tamurlane had battered their way down the Khyber Pass to weaken the Hindus’ hold on the great Gangetic Plain. For two centuries, the Moslem Mogul emperors had imposed their sumptuous and implacable rule over most of India, spreading in the wake of their martial legions the message of Allah, the One, the Merciful.[Freedom at Midnight 36]While the British were actually occupying India, post-Mughal colonialism in the form of Persian poetry, literature, and the general “sumptuousness” of its art and architecture held sway. The Persian language begot Urdu, often described by linguists as a “camp language” of the Muslim invaders of the Subcontinent. However, Persian, Arabic, and Hindi had come together to create a new language for the poetry, literature, arts, and in general the “high culture” of today’s Indian Muslims. Jawaharlal Nehru, in his definitive history of India entitled Discovery of India, wrote,The Mughals were outsiders and strangers to India and yet they fitted into Indian structure with remarkable speed and began the Indo-Mughal period.... Their dynasties became completely Indianized with their roots in India, looking upon India as their homeland, and the rest of the world as foreign.[236]A synthesis worked itself out: new styles of architecture arose; food and clothing changed; and life was affected and varied in many other ways.... The Persian language became the official court language and many Persian words crept into popular use.[237]Persian was the lingua franca of the incoming Muslims from AD 1193 onward, and Persian literature became the favored literature of India for approximately five centuries [Ali 3–4].It is in this tradition of post-Mughal Urdu high culture that Rushdie grew up. In a 1983 interview with Michael Kaufman, Rushdie said,My grandfather, my father’s father, was a good Urdu poet. My father is not a writer but he’s a very literary and literate man, a student of both Arabic and Persian Literature and of Western Literature. At Cambridge he was quite scholarly. So I grew up in an atmosphere of books. And both my parents, in their different ways, were very gifted storytellers.

Objectives: to assess physicians’ and patients’ views in Saudi Arabia towards involving the patient versus the family in the process of diagnosis disclosure and decision-making, and to compare them with views from the USA and Japan.Design: A self-completion questionnaire was translated to Arabic and validated.Participants: Physicians from different specialties and ranks and patients in a hospital or attending outpatient clinics from 6 different regions in KSA.Results: In the case of a patient with incurable cancer, 67% of doctors and 51% of (...) patients indicated that they would inform the patient in preference to the family of the diagnosis . Assuming the family already knew, 56% of doctors and 49% of patients would tell the patient even if family objected . However, in the case of HIV infection, 59% of physicians and 81% of patients would inform the family about HIV status without the patient’s consent . With regards to withholding ventilatory support, about 50% of doctors and over 60% of patients supported the use of mechanical ventilation in a patient with advanced cancer, regardless of the wishes of the patient or the family. Finally, the majority of doctors and patients were against assisted suicide.Conclusions: Although there was more recognition for a patient’s autonomy amongst physicians, most patients preferred a family centred model of care. Views towards information disclosure were midway between those of the USA and Japan. Distinctively, however, decisions regarding life prolonging therapy and assisted suicide were not influenced to a great extent by wishes of the patient or family, but more likely by religious beliefs.
