Rorschach Comprehensive System Data for a Sample of 100 Adult Nonpatients From the Belgian French-Speaking Community

This article presents normative data for the Rorschach Comprehensive System (CS) on 100 adult nonpatients from the Belgian French-speaking community. We compare our Belgian sample to a French one (Sultan et al., 2004), data of Exner's (Exner & Erdberg, 2005) and a Californian sample (Shaffer, Erdberg, & Haroian, 1999). Each sample's specific characteristics are explored, as well as findings provided by sample-specific comparisons. Exner's data, ultimate normative reference for the CS, differ significantly from the three other samples for many variables. Cultural factors, examiner's level of experience, as well as participants' selection and recruitment, presumably flow into calculated differences between the four samples. Our findings indicate the necessity for constituting normative data for different communities, as well as the indispensability of examiners' familiarity with the CS, in order to provide reliable clinical information.
Performance evaluation and prediction of open source speech engine on multicore processors

This paper quantifies the performance of the core part of voice driven web using free and open source speech engine; the speech engine which is very high computation demanding, it consists of Automatic Speech Recognition (ASR) and Text To Speech (TTS). Two open source programs, Sphinx-4 and FreeTTS-1.2. 2 are used for ASR and TTS respectively. These two programs are executed on 2 different hardware multicore processors with 4 hyperthreaded cores, and 8 cores respectively. The response time with respect to the load variance and the number of cores is measured and predicted using a linear regression model. The results show that, the response time is linear with respect to the input length, this property can be used to directly predict the response for any input length. Moreover, though the response time and the speed up increases as the number of cores increases, the regression coefficients and number of threads reveal that ASR benefits from multicore. The speedup factor for ASR is 1.56 for 8 cores. However for FreeTTS, though being sequential the speed up from the program itself is insignificant, there is about 1. 43 speedup for 8 cores, that comes from the system's contribution. Our findings show that the generalization of the results for multicore processor does not apply to hyperthreading. This paper presents the investigation that is useful for educators, researchers, and applications' developer in voice based applications 'domain.
Mentoring for new headteachers: recent British experience

Reports selected findings from a national evaluation of a British pilot scheme for mentoring new primary and secondary headteachers. Information was collected by questionnaire from 238 new headteachers, from 303 experienced headteachers who acted as mentors and via 16 detailed case studies of reportedly successful pairs. Deals with the nature and impact of the mentoring process and the characterisitics of successful mentoring. Mentoring was judged to be a success by the overwhelming majority of participants because it offered considerable practical help with pressing problems and brought benefits which were distinct from other forms of headteacher training and support. Discusses major implications for practice, research and policy and concludes that mentoring should be offered as an integral part of national strategy for the management development of headteachers.
Efficient evolution-based clustering of high dimensional data streams with dimension projection

SE-Stream is an evolution-based stream clustering method that supports high dimensional data streams. SE-Stream is able to monitor and detect change in the clustering structure during the progression of data streams. In this paper, we improve performance of SE-Stream by reducing its execution time and increasing its cluster quality. SE-Stream reduces complexity of stream processing by determining appropriated subset of dimensions of each active cluster to express cluster specific characteristics during the progression of data streams. With elimination of redundant operations, SE-Stream is improved both in terms of cluster quality and execution time. Experimental results on two real-world datasets show that SE-Stream outperforms its previous version in terms execution time. Further, the cluster quality in terms of both purity and f-measure has been considerably improved. Compared with HPStream, a state of the art algorithm for projected clustering of high dimensional data streams, SE-Stream outperforms in terms of cluster quality and yields comparable execution time.
Capitalizing on a Sport's Association with an International Destination: The Illustrative Example of Tae Kwon Do

Destination marketers seek to capitalize on sport by appealing to the sport's subculture and by bundling sport with other tourism opportunities. The potential contributions of specially constructed sport opportunities are examined by exploring the contributions that a park devoted to the heritage and practice of tae kwon do can make to American tae kwon do practitioners' interests and intent for travel to Korea. Nine elements were studied using conjoint analysis: price, three park features (tae kwon do competition, tae kwon do cultural heritage and tae kwon do master classes), three typical tours (a tour of Seoul, a modern history tour, and a tour to experience traditional Korean culture), and two physical activities (a local sports package and participation in another traditional Korean martial art). Together, the three opportunities at Tae Kwon Do Park accounted for almost one-third of the aggregate sample's utility for a trip to Korea. Cluster analysis identified four segments: Heritage Seekers, Competitive Tourists, Culturally Conscious Competitors, and Price Sensitives. Opportunities provided by Tae Kwon Do Park were more than sufficient to overcome the negative utility associated with price for all but the Price Sensitives, and all four segments valued some tourism opportunities beyond tae kwon do. However, the mix of preferred activities and tours varied significantly by segment. Segment was predicted by age, a desire to learn about Korea, a desire to master tae kwon do, years of involvement in tae kwon do, role in tae kwon do and level of belt. The likelihood of purchasing a trip to Korea rose with higher levels of belt and as social identity rose, but was lower when financial constraints or knowledge and interest constraints rose. Segment moderated the effect of ethnicity and social motivation on the likelihood of travel to Korea. It is concluded that involvement in a sport can be leveraged to promote tourism to a destination when the destination has a meaningful association with the sport.
Video search reranking through random walk over document-level context graph

Multimedia search over distributed sources often result in recurrent images or videos which are manifested beyond the textual modality. To exploit such contextual patterns and keep the simplicity of the keyword-based search, we propose novel reranking methods to leverage the recurrent patterns to improve the initial text search results. The approach, context reranking, is formulated as a random walk problem along the context graph, where video stories are nodes and the edges between them are weighted by multimodal contextual similarities. The random walk is biased with the preference towards stories with higher initial text search scores - a principled way to consider both initial text search results and their implicit contextual relationships. When evaluated on TRECVID 2005 video benchmark, the proposed approach can improve retrieval on the average up to 32% relative to the baseline text search method in terms of story-level Mean Average Precision. In the people-related queries, which usually have recurrent coverage across news sources, we can have up to 40% relative improvement. Most of all, the proposed method does not require any additional input from users (e.g., example images), or complex search models for special queries (e.g., named person search).
On a Cut-Matching Game for the Sparsest Cut Problem

We study the following game between a “cut” player C and a “matching” player M. The game starts with an empty graph G on n vertices. In each round, the cut player chooses a bisection (S, S) of vertices and the matching player then adds a perfect matching M (not necessarily belonging to G) between S and S to the (multi-)graph G. The choices of the players in each round may depend on those in the previous rounds. The game ends when G becomes an edge-expander. The value of this game, denoted by val(n, C,M), is the total number of rounds in the game before it ends. We study this game for its connection with the Sparsest Cut problem in undirected graphs: if there is a polynomial-time cut player Cf such that val(n, Cf ,M) ≤ f(n) for all M, then there is a polynomial-time O(f(n))-approximation algorithm for the Sparsest Cut problem. We show that there is no cut player C, even unbounded-time, that can ensure val(n, C,M) = o( √ gap(n)) for all matching players M, where gap(n) is the integrality gap of the well-studied SDP with triangle inequality constraints for the Sparsest Cut problem. Recall that gap(n) = Ω(log log n) [5]. Thus, we prove that this approach cannot yield a o( √ gap(n))-approximation (and in particular, o( √ log log n)-approximation) algorithm for this problem. Furthermore, we show that there is a (super-polynomial time) cut player C such that, for all M, we have val(n, C,M) = O(log n).
Controlling the regiospecificity and coupling of cytochrome P450cam: T185F mutant increases coupling and abolishes 3‐hydroxynorcamphor product

Cytochrome P450cam (P450CIA1) catalyzes the hydroxylation of camphor and several substrate analogues such as norcamphor and 1‐methyl‐norcamphor. Hydroxylation was found experimentally at the 3, 5, and 6 positions of norcamphor, but only at the 5 and 6 positions of 1‐methyl‐norcamphor. In the catalytic cycle, the hydroxylation of substrate is coupled to the consumption of NADH. For camphor, the degree of coupling is 100%, but for both norcamphor and 1‐methyl‐norcamphor, the efficiency is dramatically lowered to 12% and 50%, respectively. Based on an examination of the active site of P450cam, it appeared that mutating position 185 might dramatically alter the product specificity and coupling of hydroxylation of norcamphor by P450cam. Analysis of molecular dynamics trajectories of norcamphor bound to the T185F mutant of cytochrome P450cam predicted that hydroxylation at the 3 position should be abolished and that the coupling should be dramatically increased. This mutant was constructed and the product profile and coupling experimentally determined. The coupling was doubled, and hydroxylation at the 3 position was essentially abolished. Both of these results are in agreement with the prediction.
Social emotional learning in a Guatemalan preschool sample: Does socioeconomic status moderate the effects of a school-based prevention program?

Researchers evaluated the effectiveness of a universal social skills program and compared social emotional knowledge on individual skills interviews with 100 Guatemalan preschool children from resource rich (N = 47) and resource poor (N = 53) backgrounds. Participant ages ranged from 3- to 6-years-old. SEL was evaluated prior and subsequent to receiving a school-based social emotional educational program. Results were analysed in terms of effectiveness of SEL by error type. Data show that preschool children from both poor and wealthy families made significant gains in social-emotional knowledge as a result of SEL instruction. In order to better understand where SEL might be improved, analyses of incorrect responses provided by children from each SES group were analysed. Findings demonstrated no significant differences between the two groups in terms of incorrect or socially unacceptable responses although, overall, the groups differed in depth of social emotional knowledge. Implications for ‘closing the gap’ between children’s social emotional development in high and low SES groups are discussed.
Long-Term Enzymatic and Phenotypic Correction in the Phenylketonuria Mouse Model by Adeno-Associated Virus Vector-Mediated Gene Transfer

Phenylketonuria (PKU) is an autosomal recessive metabolic disorder caused by a deficiency of phenylalanine hydroxylase (PAH). The accumulation of phenylalanine leads to severe mental and psychomotor retardation, and hypopigmentation of skin and hair. Low-phenylalanine diet therapy can prevent irreversible damage if instituted from birth. However, poor compliance with the strict lifelong dietary therapy leads to various neurologic and behavioral problems. To develop a safe and promising gene therapy method for PKU, we investigated whether a recombinant adeno-associated virus could be used as a PAH gene transfer vector to reduce the excessive phenylalanine level in the PKU mouse model. A recombinant adeno-associated virus vector encoding the human PAH gene (rAAV-hPAH), driven by EF1-α promoter, was infused into PAH-deficient mice, Pahenu2, via the hepatic portal vein. Two weeks after injection, the plasma phenylalanine level dramatically decreased to 360 μM in male PKU mice, accompanied by the coat color changing to black. The mean plasma phenylalanine level of untreated PKU mice was 1800 μM. The PAH enzyme activities of treated mice increased to 10–17% of wild-type mice. No signs of liver toxicity were observed after gene transfer. The biochemical and phenotypic corrections were sustained for up to 25 wk (25-wk detection period). In contrast, the treatment was less effective in female PKU mice. These results indicate that recombinant adeno-associated virus vector-mediated gene therapy can be a useful therapeutic candidate for patients with PKU. Further studies are needed to clarify the differences in PKU pathogenesis in males and females, and to explore alternative administration routes besides hepatic portal vein injection.
The Evolutionist, the Creationist, and the ‘Unsure’: Picking-Up the Wrong Fight?

The public acceptance of evolution is under constant scrutiny. Surveys and polls regularly measure whether the public accepts evolutionist or creationist views. The differences between groups, such as people from various countries, are then explained by variations in religious views. But what is often overlooked, is that the data also show that a large proportion of the population, about one-third, is unsure what to believe. This figure generally goes unnoticed. We argue that the emphasis on religious variables obscures another, perhaps more important, variable: the conceptual understanding of evolution. This factor may help explain why so many people are unsure about evolution and offers a greater potential to increase public understanding and acceptance of the theory, perhaps with the active involvement of science educators.
Joint probability-algebraic decoding for tail-biting codes used in LTE system

Tail-biting codes are the main control channel coding form for the LTE system. The WAVA algorithm is one of the widely used as the decoding algorithm of tail-biting codes. To fully make use of the information on the algebra structure of the tail-biting codes, we combined the WAVA algorithm with the algebraic decoding, and proposed a new joint probability-algebraic decoding algorithm. Simulation results show that, compared with the single probability decoding, the new algorithm has better performance on the error correction.
Meta-analyzing the relationship between grades and job performance.

Employers and academics have differing views on the value of grades for predicting job performance. Employers often believe grades are useful predictors, and they make hiring decisions that are based on them. Many academics believe that grades have little predictive validity. Past meta-analyses of the grades-performance relationship have suffered either from small sample sizes or the inability to correct observed correlations for research artifacts. This study demonstrated the observed correlation between grades and job performance was.16. Correction for research artifacts increased the correlation to the.30s. Several factors were found to moderate the relationship. The most powerful factors were the year of research publication and the time between graduation and performance measurement.
Fluorophore‐assisted light inactivation produces both targeted and collateral effects on N‐type calcium channel modulation in rat sympathetic neurons

Fluorophore‐assisted light inactivation (FALI) is a method to inactivate specific proteins on a time scale of seconds to minutes using either diffuse or coherent light. Here we examine a novel FALI modality that utilizes a fluorescein‐conjugated polypeptide, α‐bungarotoxin (BTX) and a 13 amino acid BTX‐binding site engineered into the N‐terminus of metabotropic glutamate receptor 8a (mGluR8a), a class C G‐protein‐coupled receptor (GPCR). The tagged mGluR8a was expressed in rat sympathetic neurons and labelled with fluorescein‐conjugated BTX (FL‐BTX). The efficacy of FALI was evaluated by monitoring mGluR8a‐mediated inhibition of calcium currents (ICa) using whole‐cell voltage‐clamp techniques. Following either wide‐field or laser illumination of FL‐BTX‐labelled neurons, mGluR8a‐mediated ICa inhibition was greatly attenuated whereas holding current and basal ICa, measures of non‐specific effects, were minimally affected. Sodium azide, a collision quencher of singlet oxygen, reduced the magnitude of FALI‐mediated effects supporting a role for reactive oxygen species in the process. Although these results were consistent with an acute inactivation of mGluR8a, the intended target, two findings confounded this interpretation. First, effects on a natively expressed signalling pathway, α2‐adrenergic receptor‐mediated ICa modulation, were observed following illumination of neurons expressing FL‐BTX‐labelled sodium channel β2 subunits or ionotropic 5‐HT3 receptors, proteins with no overt relationship to GPCR signalling pathways. Second, GPCR‐independent ICa modulation induced with intracellular guanylyl imidophosphate was also attenuated by FALI. These data challenge the assumption that the fluorophore‐tagged protein is the sole target of FALI and provide evidence that collateral damage to proximal proteins occurs following fluorophore illumination.
Family narratives and migration dynamics: Barbadians to Britain

The global dimension of migration, played out in international labour markets and mediated by the manoeuvres of the host polities, engages with a home‐based social and cultural history which furnishes Caribbean migrants with their own agenda, in which family plays a key role. The use of transgenerational life‐stories to explore family dynamics and family narratives can contribute to an understanding of the history and culture of migration and the process by which such a culture is transmitted and transformed across generations. This article takes three case studies of Barbadian migrant families from a larger quota sample.
Analysis and augmentation of the Duffy transformation for near-singular integrals

This paper presents a singularity cancellation transformation for dealing with weak, near-singular integral kernels on triangular surface domains, as encountered in the method of moments (MoM). The main benefit of singularity cancellation quadrature schemes is that it is purely numerical, with no analytical evaluations of integrals required. The transformation presented here is based on augmenting the well-known Duffy transformation in a systematic way, such that its shortcomings are addressed. This augmented Duffy transformation performs very well in comparison to other, existing methods.
A pose estimation method of a moving target based on off-board monocular vision

Pose estimation plays a vital role in landing guidance of quadcopter unmanned aerial vehicles. In this paper, a continuous-time optimization method is proposed to estimate the pose of a moving object only using an off-board camera. The optimization time that can vary depending upon the desired accuracy and computational speed, and it is finally transferred into solving an ordinary differential equation. Based on the proposed method, a pose estimation system with a camera and a pan-tilt unit is established. The system accuracy and algorithm correctness are tested in an experiment with a moving board as the target. Experimental results indicate that the proposed method can track a moving target and estimate its position and attitude in real time. Therefore, it will be promising to use this method in landing guidance of quadcopter unmanned aerial vehicles.
Recommended surface EMG electrode position for wrist extension and flexion

To obtain a high-quality surface electromyography (EMG) recording, the signal must be acquired as far as possible from the muscle innervation and tendon zone. This study presents a technique to indicate better electrode positions for surface EMG of the upper limb muscles during wrist extension and flexion. Ten volunteers participated in this research. Surface EMG signals were collected from flexor carpi radialis and extensor carpi radialis muscles. Three different electrode positions with 2 cm internal distance between the bipolar electrodes were investigated. The duration of muscle contraction was selected using the mean absolute value method for quantification, and the qualitative signal was observed through visual inspection. The power spectral density and signal-to-noise ratio were applied to compare and select the most feasible electrode position. The optimal signal from the flexor carpi radialis muscles was presented at 90%. The optimal position for the extensor carpi radialis muscles was shown at 90% of the electrode position over the forearm length. The presented method should be observed as an important step in every surface EMG application and research to ensure high quality of the signal.
Detecting Movement of Beacons in Location-Tracking Wireless Sensor Networks

Localization is a critical issue in wireless sensor networks. In most localization schemes, there are beacons being placed as references to determine the positions of objects or events appearing in the sensing field. The underlying assumption is that beacons are always static. In this work, we define a new Beacon Movement Detection (BMD) problem. Assuming that there are unnoticed changes of locations of some beacons in the system, this problem is concerned about how to automatically monitor such situations and identify these beacons. Removal of such beacons in the positioning engine may improve the localization accuracy. Two schemes are proposed to solve the BMD problem. Finally, we evaluate how these solutions can improve the accuracy of localization schemes in case that there are unnoticed movement of some beacons. Simulation results show that our solutions alleviate 53% the decrease of positioning accuracy caused by the exceptional beacon movement.
