Abstract
The cerebellum is involved in motor learning of new procedures both during actual execution of a motor task and during observational training. These processes are thought to depend on the activity of a neural network that involves the lateral cerebellum and primary motor cortex (M1). In this study, we used a twin-coil TMS technique to investigate whether execution and observation of a visuomotor procedural learning task is related to modulation of cerebello-motor connectivity. We observed that, at rest, a magnetic conditioning pulse applied over the lateral cerebellum reduced the motor-evoked potentials obtained by stimulating the contralateral M1, indicating activation of a cerebello-motor connection. Furthermore, during procedural learning, cerebellar stimulation resulted in selective facilitation, not inhibition, of contralateral M1 excitability. The effects were evident when motor learning was obtained by actual execution of the task or by observation, but they disappeared if procedural learning had already been acquired by previous observational training. These results indicate that changes in cerebello-motor connectivity occur in relation to specific phases of procedural learning, demonstrating a complex pattern of excitatory and inhibitory drives modulated across time.
A Candidate for the Attentional Bottleneck: Set-size Specific Modulation of the Right TPJ during Attentive Enumeration
Authors: Vetter Petra , Butterworth Brian , Bahrami Bahador 
Published: March 2010

Abstract
Several recent behavioral studies have shown that the enumeration of a small number of items (a process termed subitizing) depends on the availability of attentional resources and is not a preattentive process as previously thought. Here we studied the neural correlates of visual enumeration under different attentional loads in a dual-task paradigm using fMRI. Relatively intact subitizing under low attentional load compared to impaired subitizing under high attentional load was associated with an increase in BOLD signal in the right temporo-parietal junction (rTPJ). Crucially, attentionally modulated response in the rTPJ was specific to small set sizes (up to 3 items) and did not occur at larger set sizes (5–7 items). This result has two implications: (1) Subitizing involves part of the fronto-parietal network for stimulus-driven attention providing neural evidence against preattentive subitizing. (2) Activity in rTPJ is set-size modulated. Together with similar evidence from studies probing visual short-term memory, this result suggests that rTPJ modulation might reflect the brain's ability to attentively handle small set sizes. Thus, the rTPJ may play an important role for the emergence of a capacity limit in both enumeration and visual short-term memory.
Medial Prefrontal Cortex Predicts Intertemporal Choice

Abstract
People often make shortsighted decisions to receive small benefits in the present rather than large benefits in the future, that is, to favor their current selves over their future selves. In two studies using fMRI, we demonstrated that people make such decisions in part because they fail to engage in the same degree of self-referential processing when thinking about their future selves. When participants predicted how much they would enjoy an event in the future, they showed less activity in brain regions associated with introspective self-reference—such as the ventromedial pFC (vMPFC)—than when they predicted how much they would enjoy events in the present. Moreover, the magnitude of vMPFC reduction predicted the extent to which participants made shortsighted monetary decisions several weeks later. In light of recent findings that the vMPFC contributes to the ability to simulate future events from a first-person perspective, these data suggest that shortsighted decisions result in part from a failure to fully imagine the subjective experience of one's future self.

Abstract
This study investigated links between working memory and speech processing systems. We used delayed pseudoword repetition in fMRI to investigate the neural correlates of sublexical structure in phonological working memory (pWM). We orthogonally varied the number of syllables and consonant clusters in auditory pseudowords and measured the neural responses to these manipulations under conditions of covert rehearsal (Experiment 1). A left-dominant network of temporal and motor cortex showed increased activity for longer items, with motor cortex only showing greater activity concomitant with adding consonant clusters. An individual-differences analysis revealed a significant positive relationship between activity in the angular gyrus and the hippocampus, and accuracy on pseudoword repetition. As models of pWM stipulate that its neural correlates should be activated during both perception and production/rehearsal [Buchsbaum, B. R., & D'Esposito, M.

Bower (Ed.), The psychology of learning and motivation: Advances in research and theory (Vol. 8, pp. 47–89). New York: Academic Press, 1974], we further assessed the effects of the two factors in a separate passive listening experiment (Experiment 2). In this experiment, the effect of the number of syllables was concentrated in posterior–medial regions of the supratemporal plane bilaterally, although there was no evidence of a significant response to added clusters. Taken together, the results identify the planum temporale as a key region in pWM; within this region, representations are likely to take the form of auditory or audiomotor “templates” or “chunks” at the level of the syllable [Papoutsi, M., de Zwart, J.

Task Context and Frontal Lobe Activation in the Stroop Task
Authors: Floden Darlene , Vallesi Antonino , Stuss Donald T. 
Published: March 2010

AbstractThe ability to step outside a routine—to select a new response over a habitual one—is a cardinal function of the frontal lobes. A large body of neuroimaging work now exists pointing to increased activation within the anterior cingulate when stimuli evoke competing responses (incongruent trials) relative to when responses converge (congruent trials). However, lesion evidence that the ACC is necessary in this situation is inconsistent. We hypothesized that this may be a consequence of different task procedures (context) used in lesion and neuroimaging studies. The present study attempted to reconcile the lesion and the fMRI findings by having subjects perform clinical and experimental versions of the Stroop task during BOLD fMRI acquisition. We examined the relationship of brain activation patterns, specifically within the anterior cingulate and left dorsolateral frontal regions, to congruent and incongruent trial types in different task presentations or contexts. The results confirmed our hypothesis that ACC activity is relatively specific to unblocked–uncued incongruent Stroop conditions that have not been used in large neuropsychological studies. Moreover, the size of the behavioral Stroop interference effect was significantly correlated with activity in ACC and left dorsolateral regions, although in different directions. The current results are discussed in terms of previous proposals for the functional roles of these regions in activating, monitoring, and task setting, and the relation of these findings to the disparate reports in recent case series is considered.
The Neural Substrates of Recognition Memory for Verbal Information: Spanning the Divide between Short- and Long-term Memory

Published: March 2010

Abstract
One of the classic categorical divisions in the history of memory research is that between short-term and long-term memory. Indeed, because memory for the immediate past (a few seconds) and memory for the relatively more remote past (several seconds and beyond) are assumed to rely on distinct neural systems, more often than not, memory research has focused either on short- (or “working memory”) or on long-term memory. Using an auditory–verbal continuous recognition paradigm designed for fMRI, we examined how the neural signatures of recognition memory change across an interval of time (from 2.5 to 30 sec) that spans this hypothetical division between short- and long-term memory. The results revealed that activity during successful auditory–verbal item recognition in inferior parietal cortex and the posterior superior temporal lobe was maximal for early lags, whereas, conversely, activity in the left inferior frontal gyrus increased as a function of lag. Taken together, the results reveal that as the interval between item repetitions increases, there is a shift in the distribution of memory-related activity that moves from posterior temporo-parietal cortex (lags 1–4) to inferior frontal regions (lags 5–10), indicating that as time advances, the burden of recognition memory is increasingly placed on top–down retrieval mechanisms that are mediated by structures in inferior frontal cortex.
From Agents to Objects: Sexist Attitudes and Neural Responses to Sexualized Targets
Authors: Cikara Mina , Eberhardt Jennifer L. , Fiske Susan T. 
Published: March 2010

AbstractAgency attribution is a hallmark of mind perception; thus, diminished attributions of agency may disrupt social–cognition processes typically elicited by human targets. The current studies examine the effect of perceivers' sexist attitudes on associations of agency with, and neural responses to, images of sexualized and clothed men and women. In Study 1, male (but not female) participants with higher hostile sexism scores more quickly associated sexualized women with first-person action verbs (“handle”) and clothed women with third-person action verbs (“handles”) than the inverse, as compared to their less sexist peers. In Study 2, hostile sexism correlated negatively with activation of regions associated with mental state attribution—medial prefrontal cortex, posterior cingulate, temporal poles—but only when viewing sexualized women. Heterosexual men best recognized images of sexualized female bodies (but not faces), as compared with other targets' bodies; however, neither face nor body recognition was related to hostile sexism, suggesting that the fMRI findings are not explained by more or less attention to sexualized female targets. Diminished mental state attribution is not unique to targets that people prefer to avoid, as in dehumanization of stigmatized people. The current studies demonstrate that appetitive social targets may elicit a similar response depending on perceivers' attitudes toward them.
The Birth of Jesus and Rama in Christian and Hindu Sacred Texts: An Exercise in New Comparative Theology
Authors: Bakker Freek L. 
Published: March 2010

AbstractOne of the most popular Christian holy days is Christmas, the celebration of the birth of Jesus Christ. Less well known, at least in the Western world, may be the Hindu festival of Ramnavmi, the celebration of the birth of Lord Rama. The central text of Christmas is Luke 2, which narrates the birth of Jesus while placing him in a certain context. The great text of Ramnavmi is the Ramcaritmanas, from which many verses are read during the ceremonies. The Ramcaritmanas is a Hindi version of the Sanskrit Ramayana epic and includes the birth story of Rama and his brothers.This article presents English translations of the texts narrating the births of Jesus and Rama, analyses these texts and compares their contents and finally draw some conclusions regarding the concept of incarnation found in these texts.
End-of-Life Issues in United States Veterinary Medicine Schools
Authors: Dickinson George E. , Roof Paul D. , Roof Karin W. 
Published: March 2010

AbstractThe purpose of this research endeavor was to determine the status of dying, death, and bereavement as topics within the curricula of the 28 veterinary medicine schools in the United States. Data were obtained via a mailed questionnaire (100% return rate). Results revealed that over 96% of the schools have offerings related to end-of-life issues, with 80% of students exposed to these offerings. The average number of hours students devote to end-of-life issues is 14.64, about the same as for U.S. medical and baccalaureate nursing schools. Topics covered most often are “euthanasia” and “communication with owners of dying animals.” Veterinary schools over-whelmingly note that dying, death, and bereavement are important topics. It might be helpful to veterinary medicine students if their own feelings regarding dying and death were addressed early in the curriculum and throughout class activities and clinical work. Veterinarians would likely relate better to animal guardians and to nonhuman animals themselves if they felt more comfortable with dying and death.
Multiple Embeddedness and Systemic Implications: Struggles over Natural Resources in Minangkabau since the Reformasi
Authors: Benda-Beckmann Franz von , Benda-Beckmann Keebet von 
Published: March 2010

AbstractThis article deals with struggles over natural resources in West Sumatra, the homeland of the Minangkabau after the end of the Suharto regime in 1998. In these processes, actors often follow ambiguous strategies in pursuing their interests. We argue that these ambiguities to a large extent derive from a combination of factors: One is the multiple embeddedness of property rights at different layers of social organisations, in particular in social and general legal relationships. The second is the systemic implication of property rights in other domains of social organisation, for instance, authority and power relations. The third is the specific complexity and concomitant legal insecurity within plural legal orders. Actors who draw on rules from different legal orders — for designing regulations, for validating transactions, and for making decisions in disputes — have to deal with the problem that property relations are embedded differently in different legal orders and have different logics and systemic implications. This often leads actors to a strange combination of highly legalistic reasoning and a very pragmatic search for solutions.
Who Shall Benefit? Conflicts among the Landless Poor in a Philippine Agrarian Reform Programme
Authors: Rutten Rosanne 
Published: March 2010

AbstractAcross plantation communities in the Philippines, farm workers are locked in struggles about their entitlement to land. Who may qualify as ‘rightful beneficiaries’ in the current government programme of land redistribution has become a deeply contentious issue. The Comprehensive Agrarian Reform Law of 1988 has produced — besides landowner resistance — an extensive renegotiation of land rights at the community level that may set landless workers against one another. This paper explores, for the sugarcane plantation region of Negros Occidental, why these intra-poor conflicts take place and how the boundaries between competing groups are drawn. Central to the analysis are: (1) a multi-actor perspective that considers the interactions of farm workers with state agencies, landowners, farm worker movements, NGOs, and different categories of the landless poor; and (2) a focus on the multiple social fields in which farm workers are involved (the fields of the state, market, social movements, landowner patronage, and the plantation community, among others), each with a defining social tie and legitimising discourse, each prompting a specific type of claim and justifying argument.
Against ‘Green Development Fantasies’: Resource Degradation and the Lack of Community Resistance in the Middle Mahakam Wetlands, East Kalimantan, Indonesia
Authors: Edwin B.P. de Jong , Nooteboom Gerben 
Published: March 2010

AbstractIn the middle Mahakam wetlands, East Kalimantan, local populations are hit hard by ecological deterioration in the form of degraded water quality, floods, depletion of fish stocks, and increasing sedimentation and aquatic weeds. In the short term, resources such as fish and wood are being depleted, while unpredictable floods and droughts cause insecurities and lengthy periods without earnings. In the longer term, resource depletion and water pollution threaten villagers’ health. Some of these environmental problems are produced by the fishing communities themselves but most are caused by outside actors, such as logging and mining companies and oil palm plantations. This article raises the question of why local fishing communities do not resist against outside actors and seeks to explain why they are unable to protect and manage their environment in a sustainable way. It challenges ‘green development fantasies’ and optimistic approaches which put primary faith in the capacity of local communities to manage their resources. We show instead that local communities are often unable to challenge and resist environmental changes. We explain this out of a lack of: (1) a clear enemy or a clear focus of opposition; (2) a single and relatively homogeneous community or shared ethnic identity; (3) strong leadership; and (4) the involvement of brokers with the outside world. In this article, optimistic ideas about the ability of local communities to benefit from, or protect, their ‘locality of value’ are seriously challenged.
Foreign Policy Instruments and Factors for Policy Change: Japan’s Security ‘Normalisation’ Reconsidered
Authors: Atanassova-Cornelis Elena 
Published: March 2010

AbstractThis article addresses the question of Japan’s security ‘normalisation’ by examining from realist and liberal perspectives the foreign policy tools Japan has used to redefine its engagement with the outside world in the post-Cold War period. It also analyses the international and domestic factors, which have underpinned that redefinition. The article argues that while Japan is more willing to consider seemingly realist foreign policy instruments, namely by strengthening its defence posture and alliance with the U.S., Japan’s so-called ‘normalisation’ does not represent a strategic policy shift towards realism. Rather, it should be seen as a mature response to the changed regional security environment in East Asia, as well as a ‘product’ of particular domestic political dynamics in Japan, especially the emergence of conservative Koizumi-like politicians. Japan’s main foreign policy approach — most recently represented by Fukuda’s diplomacy — remains largely a liberal one and stresses the promotion of multilateralism, peaceful cooperation and economic diplomacy.
Medieval Commentators on Future Contingents in De Interpretatione 9
Authors: Knuuttila Simo 
Published: March 2010

AbstractThis article considers three medieval approaches to the problem of future contingent propositions in chapter 9 of Aristotle’s De Interpretatione. While Boethius assumed that God’s atemporal knowledge infallibly pertains to historical events, he was inclined to believe that Aristotle correctly taught that future contingent propositions are not antecedently true or false, even though they may be characterized as true-or-false. Aquinas also tried to combine the allegedly Aristotelian view of the disjunctive truth-value of future contingent propositions with the conception of all things being timelessly present to God’s knowledge. The second approach was formulated by Peter Abelard who argued that in Aristotle’s view future contingent propositions are true or false, not merely true-or-false, and that the antecedent truth of future propositions does not necessitate things in the world. After Duns Scotus, many late medieval thinkers thought like Abelard, particularly because of their new interpretation of contingency, but they did not believe, with the exception of John Buridan, that this was an Aristotelian view.
The Prior Analytics in the Latin West: 12th-13th Centuries
Authors: Ebbesen Sten 
Published: March 2010

AbstractThis study contains three parts. The first tries to follow the spread of the study of the Prior Analytics in the first two centuries during which it was at all studied in Western Europe, providing in this connection a non-exhaustive list of extant commentaries. Part II points to a certain overlap between commentaries on the Prior Analytics and works from the genre of sophismata. Part III lists the questions discussed in a students’ compendium from about the 1240s and in six commentaries per modum quaestionis from the 1270s through the 1290s.
Three Conceptions of Formal Logic
Authors: Paul Thom 
Published: March 2010

AbstractAristotle’s logical and metaphysical works contain elements of three distinct types of formal theory: an ontology, a theory of consequences, and a theory of reasoning. His formal ontology (unlike that of certain later thinkers) does not require all propositions of a given logical form to be true. His formal syllogistic (unlike medieval theories of consequences) was guided primarily by a conception of logic as a theory of reasoning; and his fragmentary theory of consequences exists merely as an adjunct to the syllogistic. When theories of consequences took centre stage in the Middle Ages, the original motivation for the theory of the syllogism was forgotten.
