A Model of the Anterior Esophagus in Snakes, with Functional and Developmental Implications

The gross anatomy of the mouth of snakes has always been interpreted as an evolutionary response to feeding demands. In most alethinophidian species, their anatomy allows limited functional independence of right and left sides and the roof and floor of the mouth as well as wide separation of the tips of the mandibles. However, locations of the tongue and glottis in snakes suggest extraordinary rearrangement of pharyngeal structures characteristic of all vertebrates. Serial histological sections through the heads of a number of colubroid species show muscularis mucosal smooth muscle fibers appearing in the paratracheal gutter of the lower jaw at varying levels between the eye and ear regions. Incomplete muscularis externa elements appear beneath the paratracheal gutter more caudally but typically at otic levels. Both muscle layers encompass more of the gut wall at more posterior levels, encircling the gut at the level of the atlas or axis. The pattern in snakes suggests developmental dissociation of dorsal and ventral splanchnic derivatives and extensive topological rearrangements of some ventral pharyngeal arch derivatives typical of most tetrapods. When snakes swallow large prey, the effective oral cavity becomes extremely short ventrally. The palatomaxillary arches function as ratchets packing the prey almost directly into the esophagus. Our findings raise questions about germ layer origins and regulation of differentiation of gut regions and derivatives in snakes and suggest that significant aspects of the evolution of lepidosaurs may be difficult to recover from bones or molecular sequence data alone.

Responsibility attribution by groups and individuals: The effects of the interaction episode

Studied the effects of formal and informal interaction styles on the extremity of responsibility attribution judgements by groups. The stimuli were eight scenarios describing typical ‘life dilemmas’, incorporating the manipulation of the following two variables in a 2 × 2 design: (a) the risky-cautious decision taken by the actor in response to the dilemma, and (b) the outcome of the decision (success-failure). Subjects (N = 130) provided judgements about the attributed responsibility of the actor, and their perception of the actor and the situation first as individuals, followed by (a) formal or (b) informal group discussion, leading to consensus judgements. Results showed that group attributions were significantly more extreme than individual attributions, but only following the informal group interaction. The actors' riskiness and success were also significantly related to the size of the extremity shift. The findings are discussed in terms of the importance of the social context and the specific interaction episode in attribution judgements, and the possible implications of the results for such real life decision-making groups as committees and interviewing panels are considered.
Picture this: emotional and political responses to photographs of the Kenneth Bigley kidnapping

The use of photographs to augment media reports of kidnapping victims in Iraq has sparked debates over the effects of such images on the public and, ultimately, the politics surrounding the event. We considered the effects of such images in a sample of British university students during the 2004 kidnapping of British citizen Kenneth Bigley. Drawing on emotions theory, we examined the effects of graphic images on emotional reactions and attitudes towards negotiations. Half of the participants were exposed to photographs of the victim that had recently been published in a national newspaper. The other half were not shown any images. As predicted, the photographs increased fear reactions amongst participants compared to no photograph controls. Fear and sympathy, but not anger, predicted attitudes towards negotiation. The photographs used in this study thus indirectly increased participants' support for negotiating with and submitting to the demands of the captors. Copyright © 2006 John Wiley & Sons, Ltd.
Synaptic properties of serotonergic growth cones in developing rat brain

In order to gain insight into the events that take place when serotonergic growth cones are remodeled into synapses, we tested the hypothesis that neurotransmitter-related properties of presynaptic terminals are already present in these growth cones before synaptogenesis begins. The ontogeny of markers for the specific reuptake of 5-HT and for 5-HT-storing synaptic vesicles was studied in isolated growth cone (IGC) fractions from developing rat brain. High- affinity 3H-imipramine binding (a marker for the plasma membrane 5-HT transporter) was significantly enriched in IGC fractions prepared before the beginning of cortical synaptogenesis [embryonic day 15 (E15) and E20]. Radioautography with 3H-imipramine or 3H-paroxetine (another marker for the transporter) confirmed that the 5-HT transporter is present in the cerebral cortex when it contains serotonergic growth cones, but not serotonergic synapses. Specific uptake of 3H-5-HT was found in IGC fractions as early as E15; this uptake was inhibited by fluoxetine. Electron microscopic radioautography demonstrated directly that growth cones were the structures in IGC fractions that took up 3H- 5-HT. The synaptic vesicle protein synaptophysin and a 45 kDa protein found specifically in serotonergic synaptic vesicles, serotonin-binding protein (SBP), were each enriched in IGC fractions from E15 to postnatal day 5; SBP immunoreactivity increased approximately 10-fold between E15 and E20. Endogenous 5-HT was detected in IGC fractions at E15 and increased in amount as development proceeded. The ratio of 5-HT to 5-hydroxyindole acetic acid suggested that 5-HT within growth cones is protected from catabolism by monoamine oxidase. Reserpine-induced depletion of 5-HT, a marker for the vesicular carrier of 5-HT, was apparent in IGC fractions at E20, but not at E15. These data suggest that properties that characterize the presynaptic components of mature serotonergic synapses develop in growth cones before synapses are formed. The early development of these properties may permit neurotransmission to be established rapidly during synaptogenesis or, alternatively, enable 5-HT to play a role in ontogeny.
Surfing the Waves of Globalization: Asia and Financial Globalization in the Context of the Trilemma

Using the “trilemma indexes” developed by Aizenman et al. (2008) that measure the extent of achievement in each of the three policy goals in the trilemma — monetary independence, exchange rate stability, and financial openness — this paper examines how policy configurations affect macroeconomic performances with focus on the Asian economies. We find that the three policy choices do not matter for per capita economic growth. However, they do matter for output volatility and the medium-term level of inflation. Greater monetary independence is associated with lower output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated if a country holds international reserves (IR) at a higher level than a threshold (about 20% of gross domestic product). Greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation level. We find that trilemma policy configurations and external finances affect output volatility mainly through the investment channel. While a higher degree of exchange rate stability could stabilize the real exchange rate movement, it could also make investment volatile, though the volatility-enhancing effect of exchange rate stability on investment can be cancelled by holding higher levels of IR. Greater financial openness helps reduce real exchange rate volatility. These results indicate that policy makers in a more open economy would prefer pursuing greater exchange rate stability and greater financial openness while holding a massive amount of IR. Asian emerging market economies are found to be equipped with macroeconomic policy configurations that help the economies to dampen the volatilities in both investment and real exchange rate. These economies’ sizeable amount of international reserves holding appears to help enhance the stabilizing effect of the trilemma policy choices, which explains the recent phenomenal buildup of international reserves in the region.
Architecture of a multi-agent system for SCADA level in smart distributed environments

Multi-agent and holonic systems have been successfully investigated for several decades; nevertheless, their real industrial applications are still rare. This paper contributes to their utilization in practice. It discusses possibilities for integration and deployment of such systems into standard or legacy automation systems, which are distributed and should satisfy common global goals. These requirements are widespread for example in the area of virtual power plants. The proposed architecture addresses a SCADA level of the automation pyramid. The results are demonstrated on a use-case dealing with a set of distributed combined heat and power units, which should be integrated into a single virtual power plant. This virtual energy source has to satisfy common goals of the whole community, which are managed centrally, and local goals in terms of heat required by users.
Culture and International Alliance Negotiations: A Sensemaking Perspective

International alliance negotiations are now a pervasive feature of the contemporary global economy. As the alliancing firms cross national boundaries to forge cooperative partnerships they face the inevitable necessity of bridging the cultural divide to ensure successful negotiation. Existing research has focused primarily on the impact of national cultural differences in shaping negotiating strategies and ensuing outcomes. Less attention has been paid to how negotiators from different cultures understand and manage the ambiguity of international alliance negotiations. We employ the theoretical lens of sensemaking to understand how negotiators embedded in different cultures manage simultaneously the task and cultural related ambiguity that they are confronted with. This perspective suggests the critical role that ‘tertius iungens’ (the ‘third who joins’) plays in facilitating the negotiation process. The ‘tertius iungens’ represents a form of intermediation that acts as a catalyst in the negotiation process. We propose three alternative types of intermediation, namely, cognitive, affective, and holistic and provide illustrative examples of these types of intermediation. We conclude by highlighting the theoretical and managerial significance of our framework and by suggesting future directions for research.
Sex Differences in Emotionality: A Multidimensional Approach

An Emotionality Survey was developed to assess sex differences in three dimensions of emotion: covert responding, interpersonal expression, and attitudes toward responses and expressions. Situational determinants of responses were also investigated. Within each of these areas, four types of emotion were distinguished: anger, fear, joy, and sadness. In general, females exceeded males in reported emotionality, but sex differences varied as a function of dimension and type of emotion. Differences were greatest for interpersonal expression, and for fear and sadness. Females also reported more of an interpersonal basis for their emotional responses. The findings suggest a sex difference in the functional significance of emotion, and support a multidimensional approach to the investigation of sex differences in emotionality.
Monocular and Stereo Methods for AAM Learning from Video

The active appearance model (AAM) is a powerful method for modeling deformable visual objects. One of the major drawbacks of the AAM is that it requires a training set of pseudo-dense correspondences over the whole database. In this work, we investigate the utility of stereo constraints for automatic model building from video. First, we propose a new method for automatic correspondence finding in monocular images which is based on an adaptive template tracking paradigm. We then extend this method to take the scene geometry into account, proposing three approaches, each accounting for the availability of the fundamental matrix and calibration parameters or the lack thereof. The performance of the monocular method was first evaluated on a pre-annotated database of a talking face. We then compared the monocular method against its three stereo extensions using a stereo database.
Dependence of EPSP Efficacy on Synapse Location in Neocortical Pyramidal Neurons

Neurons receive thousands of synaptic inputs throughout elaborate dendritic trees. Here we determine the somatic impact of excitatory postsynaptic potentials (EPSPs) generated at known dendritic sites in neocortical pyramidal neurons. As inputs became more distal, somatic EPSP amplitude decreased, whereas use-dependent depression increased. Despite marked attenuation (>40-fold), when coactivated within a narrow time window (∼10 milliseconds), distal EPSPs could directly influence action potential output following dendritic spike generation. These findings reveal that distal EPSPs are ineffective sources of background somatic excitation, but through coincidence detection have a powerful transient signaling role.
Document Counting in Practice

We address the problem of counting the number of strings in a collection where a given pattern appears, which has applications in information retrieval and data mining. Existing solutions are in a theoretical stage. We implement these solutions and develop some new variants, comparing them experimentally on various datasets. Our results not only show which are the best options for each situation and help discard practically unappealing solutions, but also uncover some unexpected compressibility properties of the best data structures. By taking advantage of these properties, we can reduce the size of the structures by a factor of 5--400, depending on the dataset.
Sights of sites: picturing heritage, power and exclusion

This paper explores the visual representations used to illustrate, promote and communicate a particular idea of heritage in the tourism literature, which provides an instance within which to examine the material consequences of a dominant discourse. This examination takes place within the context of current New Labour policy initiatives, which have put forward a new role for heritage, both in terms of the touristic experiences it can provide and as an instrumental tool for social inclusion and civic engagement. It is argued in this paper that these consciously designed objectives have also opened up a conceptual space within which images of heritage are drawn upon to undertake a course of ideological work that affectively reaffirms and legitimizes the cultural symbols of an elite social group as a consensual representation of national heritage.
Modularity and Specialization in Superfamily 1 and 2 Helicases

The family of nucleic acid (NA) strand separation enzymes known as helicases are found in all organisms and participate in a wide variety of cellular processes. The central reaction catalyzed is always the same: hydrolysis of a nucleoside triphosphate (NTP; usually ATP) is coupled to the separation of an NA duplex, be it DNA-DNA, DNA-RNA, or RNA-RNA. This central process is required in almost every aspect of NA metabolism in the cell, including chromosomal and plasmid replication, transcription, translation, RNA processing, and DNA recombination and repair (30, 46). This widespread usage may be seen by examining the cellular complement of helicases; for example, at least 12 putative DNA helicases have been identified in the genome of Escherichia coli, while it has been estimated that more than 2% of the Saccharomyces cerevisiae genome encodes helicase-related proteins (48).
Abdominal Inflammatory Myofibroblastic Tumor: Report on Four Cases and Review of Literature

Background The Abdominal Inflammatory Myofibroblastic Tumor (AIMT) is a rare tumor with unknown etiology which usually occurs in children and adolescents. It is composed of myofibroblastic spindle cells intermixed with inflammatory cells. We present four cases of AIMT. Cases Presentation We herein present four cases of AIMT in different ages (range: 3.5 to 13 years) and in different organs (stomach, periduodenal, mesenteric, and colon). There were two females and two males. The main symptoms were abdominal pain/mass/obstruction, vomiting, and weight loss. In all four patients, diagnosis was made by laparatomy and pathologic examination of excised mass lesion. Three patients underwent complete excision and no residual disease was present, one patient received chemotherapy due to tumor recurrences. The patients were followed up in average for four years. Conclusion As the imaging and laboratory tests are non-specific, the diagnosis of AIMT is rarely made before surgery. AIMT should, therefore, be considered when a mass arises in an unusual location in the pediatric age group. Complete surgical resection should be performed whenever possible and the child should be kept on long-term follow-up.
Laboratory evaluations of a wild crucifer Barbarea vulgaris as a management tool for the diamondback moth Plutella xylostella (Lepidoptera: Plutellidae).

The term 'dead-end trap cropping' has recently been proposed to identify a plant that is highly attractive for oviposition by an insect pest, but on which offspring of the pest cannot survive. The potential of the wild crucifer Barbarea vulgaris R. Br. to allure and serve as a dead-end trap crop for the diamondback moth Plutella xylostella (L.), an important pest of cruciferous crops worldwide, was examined in laboratory experiments. When P. xylostella adults were provided with a dual-choice of plants of B. vulgaris, and Chinese cabbage Brassica campestris (L.), in one arena, adult moths laid 2.5-6.8 times more eggs on the former than on the latter. When P. xylostella adults were provided with a dual-choice of plants of B. vulgaris and common cabbage Brassica oleracea L. , adult moths laid virtually all their eggs on the former and ignored the latter. Nearly all P. xylostella eggs laid on the three species of plants hatched successfully, but nearly all individuals on plants of B. vulgaris died as neonates or early instar larvae, while 87-100% of the larvae on Chinese cabbage and common cabbage survived to pupation. Dual choice tests with a Y-tube olfactometer showed that volatiles from B. vulgaris were much more attractive to P. xylostella adults than those from common cabbage. The results demonstrate that B. vulgaris has a great potential as a dead-end trap crop for improving management of P. xylostella. Factors that may influence the feasibility of using B. vulgaris as a trap crop in the field are discussed, and ways to utilize this plant are proposed.
Complexity in practice

Theories of social practice point to a wide domain of largely tacit social accommodations as the source from which the dynamic structures of social practices are sedimented. The strategy-as-practice initiative seeks to use these insights to widen our appreciation of the origins and evolution of strategy in organizations. This ar ticle suggests that this domain, and its components, can be substantively and literally represented as a complex adaptive system. Complexity gives access to a considerable body of theor y on the emergent orders that may arise from social practice, and on the evolution of social order over time. These carry impor tant implications for the scope of practitioners' agency in leading strategic change, for the locus of strategy in organizations, and for the design of research strategies to investigate these complex phenomena.
Private Link Exchange over Social Graphs

Currently, most of the online social networks (OSN) keep their data secret and in centralized manner. Researchers are allowed to crawl the underlying social graphs (and data) but with limited rates, leading to only partial views of the true social graphs. To overcome this constraint, we may start from user perspective, the contributors of the OSNs. More precisely, if users cautiously collaborate with one another, they can use the very infrastructure of the OSNs to exchange noisy friend lists with their neighbors in several rounds. In the end, they can build local subgraphs, also called local views of the true social graph. In this paper, we propose such protocols for the problem of \textit{private link exchange} over social graphs. The problem is unique in the sense that the disseminated data over the links are the links themselves. However, there exist fundamental questions about the feasibility of this model. The first question is how to define simple and effective privacy concepts for the link exchange processes. The second question comes from the high volume of link lists in exchange which may increase exponentially round after round. While storage and computation complexity may be affordable for desktop PCs, communication costs are non-trivial. We address both questions by a simple $(\alpha,\beta)$-exchange using Bloom filters.
Blessing same-sex unions and the invention of a ‘genuine homosexuality’ in the Church of Sweden

The Church of Sweden decided to introduce a blessing ceremony for same-sex couples in 2005. This article examines how the blessing ceremony was made possible by the invention of a new ‘genuine’ homosexuality. Theological issues concerning ‘sin’, ‘grace’, eschatology, ‘God’, anthropology and the status of the Bible and historical texts came to be understood and articulated in new ways when the idea of ‘genuine’ homosexuality began to be discussed and gained acceptance in the Church of Sweden. I argue that the decision to introduce a blessing ceremony not only represented a change in how the Church of Sweden regards homosexuality and same-sex relationships, thereby formulating and reformulating well-established Christian teachings and doctrines, but also that new exclusions were articulated which strengthened the hegemonic and heteronormative order. The behaviours and social forms that were excluded include bisexuality, promiscuity, promiscuous homosexuality, and polyamorous relationships.
QUWI: An Arabic and English Handwriting Dataset for Offline Writer Identification

This paper presents a new offline dataset called the Qatar University Writer Identification dataset (QUWI). This dataset contains both Arabic and English handwritings and can be used to evaluate the performance of offline writer identification systems. It consists of handwritten documents of 1017 volunteers of different ages, nationalities, genders and education levels. The writers were asked to copy a specific text and to generate a random text, which allows the dataset to be used for both text-dependent and text-independent writer identification tasks. We describe the gathering and processing steps and define several evaluation tasks regarding the use of this dataset.
