Dealing with Feelings: Characterization of Trait Alexithymia on Emotion Regulation Strategies and Cognitive-Emotional Processing

Background Alexithymia, or “no words for feelings”, is a personality trait which is associated with difficulties in emotion recognition and regulation. It is unknown whether this deficit is due primarily to regulation, perception, or mentalizing of emotions. In order to shed light on the core deficit, we tested our subjects on a wide range of emotional tasks. We expected the high alexithymics to underperform on all tasks. Method Two groups of healthy individuals, high and low scoring on the cognitive component of the Bermond-Vorst Alexithymia Questionnaire, completed questionnaires of emotion regulation and performed several emotion processing tasks including a micro expression recognition task, recognition of emotional prosody and semantics in spoken sentences, an emotional and identity learning task and a conflicting beliefs and emotions task (emotional mentalizing). Results The two groups differed on the Emotion Regulation Questionnaire, Berkeley Expressivity Questionnaire and Empathy Quotient. Specifically, the Emotion Regulation Quotient showed that alexithymic individuals used more suppressive and less reappraisal strategies. On the behavioral tasks, as expected, alexithymics performed worse on recognition of micro expressions and emotional mentalizing. Surprisingly, groups did not differ on tasks of emotional semantics and prosody and associative emotional-learning. Conclusion Individuals scoring high on the cognitive component of alexithymia are more prone to suppressive emotion regulation strategies rather than reappraisal strategies. Regarding emotional information processing, alexithymia is associated with reduced performance on measures of early processing as well as higher order mentalizing. However, difficulties in the processing of emotional language were not a core deficit in our alexithymic group.
Classical and Neoclassical Indeterminacy in One-Shot Versus Ongoing Equilibria

I analyze two connections between neoclassical and classical economics. First, I consider the indeterminacy that arises for both schools: In the neoclassical theories of overlapping generations and of factor pricing and in Sraffa's price theory. Neoclassical indeterminacy occurs only in environments where relative prices can change through time; otherwise, determinacy obtains. Although these results challenge the Sraffian position on indeterminacy, the classical principle that current economic activity is embedded in the past proves to be a powerful insight: It establishes the robustness of factor-price indeterminacy and casts doubt on the importance of overlapping-generations indeterminacy. Second, I argue that recent claims that capital-theoretic paradoxes arise in intertemporal general equilibrium modes, not just in aggregative theory, cannot be validated.
Is there a J-curve in Nigerian agricultural sector?

The paper empirically tests the existence of the J-curve hypothesis using Nigerian sectoral data. The hypothesis asserts that adjustment to a disturbance in payments is not instantaneous since a certain period of time would have to elapse before variation in the exchange-rate can restore equilibrium in the trade balance. In this study the Jcurve hypothesis was tested using data on the Nigerian agricultural sector. The analyzed model is a multiplierbased framework which imposes an Almon lag structure on the exchange rate regimes The empirical results indicate that the J-curve does not exist in Nigerian agricultural sector precisely in the long-run since the pattern of lag between the exchange rate depreciation and the trade balance resembles more of an asymmetric S-shape of a horizontal S.
The Large-Scale Axisymmetric Magnetic Topology of a Very-Low-Mass Fully Convective Star

Understanding how cool stars produce magnetic fields within their interiors is crucial for predicting the impact of such fields, such as the activity cycle of the Sun. In this respect, studying fully convective stars enables us to investigate the role of convective zones in magnetic field generation. We produced a magnetic map of a rapidly rotating, very-low-mass, fully convective dwarf through tomographic imaging from time series of spectropolarimetric data. Our results, which demonstrate that fully convective stars are able to trigger axisymmetric large-scale poloidal fields without differential rotation, challenge existing theoretical models of field generation in cool stars.
DuplicateSpace: Enhancing operability of virtual 3D objects by asymmetric bimanual interaction

DuplicateSpace is a 3D interaction platform that enables direct manipulation by two-handed interaction in a virtual environment. Our platform aims to enhance the operational feasibility and realistic feeling of the virtual world by allowing operability of virtual objects through real-world metaphors. On this platform, we apply asymmetric bimanual interaction, which combines a bare hand and a hand-held device, to provide direct manipulation by synchronizing a virtual space and a physical space. We investigate the role of the two handed modalities and suggest a tangible interaction design to enhance the operability of virtual 3D objects. Through an informal user study under DuplicateSpace, we estimate the enhancement of familiarity to the virtual world.
A comparative analysis of existing oligonucleotides selection algorithms for microarray technology

In system biology, DNA microarray technology is an indispensable tool for the biological analysis involved at the level of the whole genome. Among the sophisticated analytical problems in microarray technology at the front and back ends, respectively, are the selection of optimal DNA oligonucleotides (henceforth oligos) and computational analysis of the genes expression data. A computational comparative analysis of the methods used to select oligos is important since the design and quality of the microarray probes are of critical importance for the hybridization experiments as well as subsequent analysis of the data. In an attempt to enhance efficient and effective design at the front end, a computational comparative analysis was performed on oligos selection tools using the barley ESTs, as well as the Saccharomyces cerevisiae, Encephalitozoon cuniculi and human genomes. The analysis also shows that a large number of the existing tools are difficult to install and configure. For cross hybridization test, most rely on BLAST and therefore design ill specific oligonucleotides. Furthermore, most are non-intuitive to use and lack important oligo design and software features.
Cooperative network behaviour analysis model for mobile Botnet detection

Recently, the mobile devices are well integrated with Internet and widely used by normal users and organizations which employ Bring Your Own Device technology. On the other hand, the mobile devices are less protected in comparison to computers. Therefore, the mobile devices and networks have now become attractive targets for attackers. Amongst several types of mobile threats, the mobile HTTP Botnets can be considered as one of the most sophisticated attacks. A HTTP Bots stealthily infect mobile devices and periodically communicate with their controller called Botmaster. Although the Bots hide their activities amongst the normal web flows, their periodic pattern has been used as a measure to detect their activities. In this paper we propose a cooperative network behaviour analysis model to identify the level of periodicity posed by mobile Bots. Finally three metrics is proposed to detect Mobile HTTP Botnets based on similarity and correlation of their group activities. Test results show that the propose model can efficiently classify communication patterns into several periodicity categories and detect mobile Botnets.
Subaru Spectropolarimetry of Markarian 573: The Hidden High-Ionization Nuclear Emission-Line Region inside the Dusty Torus

We report the results of our high-quality spectropolarimetric observation of the narrow-line region in a nearby Seyfert 2 galaxy, Mrk 573, with the Subaru Telescope. The polarized flux spectrum of Mrk 573 shows not only prominent scattered broad Hα emission but also various narrow forbidden emission lines. We find that the measured polarization degree of the observed forbidden emission lines is positively correlated with the ionization potential of the corresponding ions and the critical density of the corresponding transitions. We discuss some possible origins of these correlations, and then we point out that the correlations are caused by the obscuration of the stratified narrow-line region in Mrk 573 by the optically and geometrically thick dusty torus, matching findings of a previous study of NGC 4258.
Unified Error Probability Analysis of Maximal-Ratio Combining with Antenna Selection in Nakagami Fading Channels

This paper presents the performance analysis of multiple-input multiple-output (MIMO) technique incorporating maximal ratio combining with transmit antenna selection (MRC/TAS) in frequency-flat Nakagami-m fading channel with single infinite series of tabulated function while the fading index is a real value. In this paper, we derived the simple expression of probability density function (pdf) for MRC/TAS (Nt, 1, Nr) scheme. The probability of outage is first evaluated. Finally, the closed-form expressions of bit error probability (BEP) have been evaluated for MRC/TAS by the effective use of pdf.
INTEGRAL and BeppoSAX Observations of the Transient Atoll Source 4U 1608–522: From Quiescent to Hard Spectral State

We report on the spectral evolution of 4U 1608–522 using observations performed as part of the long-term Galactic bulge monitoring program with INTEGRAL. The data set includes the 2005 April outburst. BeppoSAX archival data (two observations, from 1998 and 2000) are also analyzed and compared with the INTEGRAL data. Three different spectral states have been identified from the hardness-intensity diagram derived from INTEGRAL: the canonical hard and soft states, as well as an intermediate state. The hard-state spectrum is well described by a weak blackbody component plus a Comptonized plasma with high electron temperature (kTe ≃ 60 keV) extending up to 200 keV without any additional cutoff. The soft spectra are characterized by a cold Comptonized plasma (kTe = 2-3 keV; 7 keV for the intermediate state) and a strong disk blackbody component. A reflection component, indicating reflection of the X-rays from the accretion disk, is also present in the soft state seen by BeppoSAX in 1998. The 2000 BeppoSAX observation reveals the source to have been in its quiescent state, which can be modeled with a neutron star atmosphere (assuming a neutron star radius of 10 km and mass 1.4 M☉) with an effective temperature kTeff of 0.1 keV, plus a power-law component with Γ ~ 3, detected for the first time in this source. This spectrum can also be modeled with a simple blackbody compatible with emission originating from a small fraction of the neutron star's surface, of radius 0.4 km.
Long-term and short-term electrophysiological effects of estrogen on the synaptic properties of hippocampal CA1 neurons

The ovarian steroids exert both long-term and short-term actions on neurons involving different cellular mechanisms. We have investigated the long-term and short-term effects of estrogen on the electrophysiological properties of CA1 neurons utilizing intracellular recordings in hippocampal slices prepared from ovariectomized female rats. An in vivo estrogen-priming paradigm was used to examine long- term genomic actions of estrogen. Subcutaneous estrogen injections 2 d prior to recording had no effect on the intrinsic membrane properties of CA1 neurons, but increased synaptic excitability by prolonging the EPSP and inducing repetitive firing in response to Schaffer collateral stimulation. Short-term effects of estrogen that presumedly involve direct membrane interactions were tested by application of steroids directly to the slice. Superfusion of 17 beta-estradiol, but not 17 alpha-estradiol, caused a rapid and reversible increase in the amplitude of the Schaffer collateral-activated EPSP. This potentiation of the EPSP by 17 beta-estradiol still occurred in the presence of the NMDA antagonist 2-amino-5-phosphonovalerate, but was blocked by the non- NMDA antagonist 6-cyano-7-nitroquinoxaline-2,3-dione. Depolarizing responses to iontophoretic pulses of exogenous glutamate were also potentiated by 17 beta-estradiol, suggesting a post-synaptic site of action. In addition, 17 beta-estradiol potentiated the responses to alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid, kainate, and quisqualate, but not NMDA, further implicating non-NMDA receptors in the short-term action of estrogen. In contrast, 17 beta-estradiol had no effect on responses to exogenous GABA or on the Schaffer collateral- induced late IPSP. (ABSTRACT TRUNCATED AT 250 WORDS)
Budgetary Participation, Locus of Control, and Mexican Managerial Performance and Job Satisfaction

The at least partially flexible connector assembly includes a slack storage tube connected to the first end of a fiber optic cable for loosely storing excess lengths of the optical fibers. The slack storage tube is typically at least partially flexible. By including a flexible slack storage tube, the connector assembly can be readily flexed, such as during installations of the fiber optic cable in which the end portion of the fiber optic cable must be bent relatively sharply. However, the slack storage tube does generally include crush resistance means for supporting the slack storage tube as the connector assembly is flexed such that the longitudinal bore defined by the slack storage tube remains open. The crush resistance means can include a wire helically wound about the slack storage tube. Alternatively, the slack storage tube can be a corrugated tube. The connector assembly also includes a number of ferrules mounted on the end portions of respective optical fibers as well as a ferrule holder for holding the ferrules in respective predetermined positions. In addition, the connector assembly can include a plug connected at a first end to the slack storage tube and having a second end that is adapted to receive and engage the ferrule holder. By disposing the ferrule holder within the second end of the plug, the plug effectively secures the ferrule holder and, in turn, the ferrules to the slack storage tube so as to form the connector assembly.
Language emergence Al-Sayyid Bedouin Sign Language

10.1 The forbidden experiment Language and culture separate humans from all other species. No human group lacks either, which must mean that both are deeply seated in human nature. What are the essential ingredients of these two most human of attributes? Our central task as linguists is to try to answer this question for language. One strategy for tackling this problem is to trace all existing human languages back to some original and so discover the fundamental properties of language. Nineteenth-century historical linguists tried to do this, with notable success, beginning from William Jones' observation that Sanskrit was so similar to Greek, Latin, Gothic, Celtic, and Persian that they must have descended from a common ancestor. Though remarkably reliable, the methods of historical linguistics are incapable of taking us back more than a few thousand years. In the nineteenth century, when most educated people believed that the world had begun no more than six thousand years before, these limitations presented no barrier to answering the question of the origin of language and historical linguistics flourished. But Charles Lyell, the founder of geology, destroyed all such hope when he argued successfully that the earth must be much older. We now know that the earth is billions of years old, that the human lineage split from the other great apes approximately six million years ago, and that anatomically modern humans have inhabited the earth for at least one hundred thousand years, emerging from Africa to spread across the globe at least fifty thousand years ago (see Dediu, this volume, Chapter 28). All of which means that we will never learn, using conventional historical linguistic methods, what the first human language was like. Another tactic that linguists have advocated is to compare many modern languages. If we can discover what they all share, sometimes called language universals, then this may tell us what the basic structure of human languages is like. But detailed comparison of many languages has revealed
Comparative Proteomic Analysis of Streptococcus suis Biofilms and Planktonic Cells That Identified Biofilm Infection-Related Immunogenic Proteins

Streptococcus suis (SS) is a zoonotic pathogen that causes severe disease symptoms in pigs and humans. Biofilms of SS bind to extracellular matrix proteins in both endothelial and epithelial cells and cause persistent infections. In this study, the differences in the protein expression profiles of SS grown either as planktonic cells or biofilms were identified using comparative proteomic analysis. The results revealed the existence of 13 proteins of varying amounts, among which six were upregulated and seven were downregulated in the Streptococcus biofilm compared with the planktonic controls. The convalescent serum from mini-pig, challenged with SS, was applied in a Western blot assay to visualize all proteins from the biofilm that were grown in vitro and separated by two-dimensional gel electrophoresis. A total of 10 immunoreactive protein spots corresponding to nine unique proteins were identified by MALDI-TOF/TOF-MS. Of these nine proteins, five (Manganese-dependent superoxide dismutase, UDP-N-acetylglucosamine 1-carboxyvinyltransferase, ornithine carbamoyltransferase, phosphoglycerate kinase, Hypothetical protein SSU05_0403) had no previously reported immunogenic properties in SS to our knowledge. The remaining four immunogenic proteins (glyceraldehyde-3-phosphate dehydrogenase, hemolysin, pyruvate dehydrogenase and DnaK) were identified under both planktonic and biofilm growth conditions. In conclusion, the protein expression pattern of SS, grown as biofilm, was different from the SS grown as planktonic cells. These five immunogenic proteins that were specific to SS biofilm cells may potentially be targeted as vaccine candidates to protect against SS biofilm infections. The four proteins common to both biofilm and planktonic cells can be targeted as vaccine candidates to protect against both biofilm and acute infections.
A “network-paging” based method for wide-area live-migration of VMs

In cloud-computing environments, migration of virtual machines (VMs) between data centers can solve many problems such as load balancing and power saving. One of the difficulties in wide-area migration, however, is the “address-warping” problem, in which the address of the VM warps from the source server to the destination server. This confuses or complicates the status of the WAN, and the LANs connected to the WAN. We propose two solutions to this problem. One is to switch an address-translation rule, and the other is to switch multiple virtual networks. The former is analogous to paging in memory virtualization, and the latter is analogous to segmentation. The “network-paging” based method is described and our evaluation results are shown. It took less than 100 ms in average to switch from the source to the destination server using this method.
Autonomous localization scheme for mobile sensor networks in fading environments

Sensor localization based on Received Signal Strength Indication (RSSI) in Wireless Sensor Networks (WSNs) takes a place in research interest because received signal strength can be measured without additional hardware. However, RSSI based localization requires static configuration for anchor nodes to achieve high localization accuracy in reasonable time. Furthermore, when sufficient number of mobile nodes are chosen as anchors, RSSI based localization accuracy is radically influenced by measurement errors of signal strength in physical environments. As a result, RSSI based localization error may increase due to anchor mobility such as a case of close anchors and a case of approximately linear anchors. In this paper, a new localization scheme is proposed to solve such problems. In addition, the proposed scheme is enhanced to work in low anchor density to minimize additional equipment cost for anchor nodes. Performance comparison and simulation results show that the proposed scheme achieves better localization accuracy in fading environments (i.e. urban, suburban or rural) compared to existing RSSI solutions.
Mechanisms of Chromosome Number Evolution in Yeast

The whole-genome duplication (WGD) that occurred during yeast evolution changed the basal number of chromosomes from 8 to 16. However, the number of chromosomes in post-WGD species now ranges between 10 and 16, and the number in non-WGD species (Zygosaccharomyces, Kluyveromyces, Lachancea, and Ashbya) ranges between 6 and 8. To study the mechanism by which chromosome number changes, we traced the ancestry of centromeres and telomeres in each species. We observe only two mechanisms by which the number of chromosomes has decreased, as indicated by the loss of a centromere. The most frequent mechanism, seen 8 times, is telomere-to-telomere fusion between two chromosomes with the concomitant death of one centromere. The other mechanism, seen once, involves the breakage of a chromosome at its centromere, followed by the fusion of the two arms to the telomeres of two other chromosomes. The only mechanism by which chromosome number has increased in these species is WGD. Translocations and inversions have cycled telomere locations, internalizing some previously telomeric genes and creating novel telomeric locations. Comparison of centromere structures shows that the length of the CDEII region is variable between species but uniform within species. We trace the complete rearrangement history of the Lachancea kluyveri genome since its common ancestor with Saccharomyces and propose that its exceptionally low level of rearrangement is a consequence of the loss of the non-homologous end joining (NHEJ) DNA repair pathway in this species.
COULD IT BE A BIG WORLD AFTER ALL? THE "SIX DEGREES OF SEPARATION" MYTH

The idea that people are connected through just "six degrees of separation," based on Stanley Milgram's "small world study," has become part of the intellectual furniture of educated people. New evidence discovered in the Milgram papers in the Yale archives, together with a review of the literature on the "small world problem," reveals that this widely-accepted idea rests on scanty evidence. Indeed, the empirical evidence suggests that we actually live in a world deeply divided by social barriers such as race and class. An explosion of interest is occurring in the small world problem because mathematicians have developed computer models of how the small world phenomenon could logically work. But mathematical modeling is not a substitute for empirical evidence. At the core of the small world problem are fascinating psychological mysteries.
Indoor Place Categorization Using Co-occurrences of LBPs in Gray and Depth Images from RGB-D Sensors

Indoor place categorization is an important capability for service robots working and interacting in human environments. This paper presents a new place categorization method which uses information about the spatial correlation between the different image modalities provided by RGB-D sensors. Our approach applies co-occurrence histograms of local binary patterns (LBPs) from gray and depth images that correspond to the same indoor scene. The resulting histograms are used as feature vectors in a supervised classifier. Our experimental results show the effectiveness of our method to categorize indoor places using RGB-D cameras.
