Pre-surgical epilepsy evaluation using 3T MRI. Do surface coils provide additional information?

PURPOSE To assess if 3T MRI can be further improved by adding surface coil imaging, in the context of detection and characterization of cerebral lesions in patients with drug-resistant epilepsy. METHODS Twenty five patients with drug-resistant epilepsy undergoing evaluation for epilepsy surgery were examined with high resolution 3T MRI. The patients were MRI-negative (n = 15), or had unclear findings (n = 10), on previous MRI at 1.0-1.5T. Surface coils were applied over the suspected epileptogenic zone after imaging in the head coil. In MRI-negative patients, placement of the coils was defined by semiological analysis, extracranial video-EEG, and, in selected cases, subtraction ictal SPECT co-registered with MRI and PET. Coil placement was re-analyzed and graded, based on the degree of convergence between different investigational modalities. RESULTS Surface coil MRI allowed visualization of the cortical lesions with somewhat better demarcation and detail, but did not contribute to detection of previously undiagnosed lesions and did not provide additional information regarding type of lesion. Possible epileptogenic lesions were detected on 3T MRI in 12 patients. No abnormalities were found in the remaining 13 patients. 3T MRI provided new or additional information about the cortex, compared with reports from previous 1.0-1.5T MRI in 5 patients (20%). CONCLUSION 3T MRI with high resolution is valuable for lesion detection, especially MCD, in patients with drug-resistant epilepsy. We question the additional contribution from supplementary surface coil imaging at 3T MRI.
Frequency-Splitting Analysis of Four-Coil Resonant Wireless Power Transfer

Based on four-coil magnetically coupled resonant wireless power transfer, this paper demonstrates, explains, and analyzes the frequency-splitting phenomenon by using the circuit theory. First, the complete and simplified models are built to describe the whole system. The numerical formulas of the system efficiency both at and away from the resonant frequency are presented. Then the frequency-splitting phenomenon is displayed and further explained mathematically and physically. An important factor for frequency splitting is introduced. The boundary condition for frequency splitting and its splitting frequency points are deduced. The amplitude-frequency and phase-frequency characteristics of the input impedance are measured and described to verify the explanation. Three related factors are studied, and the sensitivity analysis is conducted. A solution is proposed that helps improve the efficiency when frequency splitting occurs. The theoretical calculations and experimental results provide a sound basis.
Curricula Equity in Required Ninth-Grade Physical Education.

Physical educators from randomly selected high schools (N = 180) in the AAHPERD Central District were surveyed via telephone regarding their required (9th grade) physical education programs. Four researchers scored the 180 instruments, and each instrument was scored independently with a 96% inter-rater reliability. For the entire sample, 52% of the activity units were team sports, 39% individual sports, 4% dance-gymnastics, and 4% adventure-cooperative-recreational. Of the 180 schools, 71% conducted programs in compliance with Title IX. Of the teachers interviewed, 88% of the females and 30% of the males taught outside their socially accepted areas, although they tended to conduct similar curricula. In general, schools delivered traditional multi-activity programs emphasizing team and lifetime sports, while 25% of the schools had programs with a primary emphasis on competitive, contact, male-oriented team activities. Thus, curricula tended to perpetuate the current socially constructed view of gender and .
Engaging employees to their jobs: Role of exchange ideology as a moderator

This article examines whether employees’ perceptions of supervisor support, distributive justice, procedural justice, and participation in decision-making are related to their job engagement. It also establishes if exchange ideology moderates between the relationships. A primary survey of 160 employees in Malaysia revealed that the four antecedents were positively and significantly related to employees’ engagement to their jobs. It also showed that unlike procedural justice, the relationship between distributive justice and job engagement was stronger, when employees have high, rather than low exchange ideology. Likewise, the relationships between employees’ perceptions of supervisor support and job engagement, as well as between employees’ participation in decision-making and job engagement were stronger when their exchange ideology were high. The implications of the research findings, limitations of this study, and suggestions for future research are also discussed. Key words: Job engagement, exchange ideology, perceived supervisor support, distributive justice, procedural justice, participation in decision-making, Malaysia.
Nonmusic Majors' Cognitive and Affective Responses to Performance and Programmatic Music Videos

This study was designed to compare the effects of different kinds of visual presentations and music alone on university nonmusic students' affective and cognitive responses to music. Four groups of participants were presented with excerpts from the first and fourth movements of Beethoven's Symphony No. 6 in F major (“Pastoral”). Two groups heard music excerpts only, one interpretation conducted by Stowkowski and one by Bernstein. One of the video groups viewed corresponding excerpts from the movie Fantasia while listening to the Stowkowski recording. A second group viewed and listened to a performance video of the Vienna Philharmonic filmed during the Bernstein recording. All students (N = 128) completed cognitive listening tests based on the excerpts, rated the music on Likert-type affective scales, and responded to two open-ended questions. Significant effects of presentation condition were found. Cognitive scores were higher for the performance video than the music plus animation video on both movements. Scores for the two music-only presentations were not significantly different from each other or the two video presentations. Although affective ratings were not significantly different in magnitude between the presentation groups, the animation video (Fantasia.) presentation ranked consistently higher in affect than the other presentations. Implications of these results regarding the effects of different types of visual information presented to music listeners are discussed.
Rethinking Packet Classification for Global Network View of Software-Defined Networking

In software-defined networking, applications are allowed to access a global view of the network so as to provide sophisticated functionalities, such as quality-oriented service delivery, automatic fault localization, and network verification. All of these functionalities commonly rely on a well-studied technology, packet classification. Unlike the conventional classification problem to search for the action taken at a single switch, the global network view requires to identify the network-wide behavior of the packet, which is defined as a combination of switch actions. Conventional classification methods, however, fail to well support network-wide behaviors, since the search space is complicatedly partitioned due to the combinations. This paper proposes a novel packet classification method that efficiently supports network-wide packet behaviors. Our method utilizes a compressed data structure named the multi-valued decision diagram, allowing it to manipulate the complex search space with several algorithms. Through detailed analysis, we optimize the classification performance as well as the construction of decision diagrams. Experiments with real network datasets show that our method identifies the packet behavior at 20.1 Mpps on a single CPU core with only 8.4 MB memory, by contrast, conventional methods failed to work even with 16 GB memory. We believe that our method is essential for realizing advanced applications that can fully leverage the potential of software defined networking.
On the (dis-)confirmability of stereotypic attributes

Two experiments investigated the linguistic abstractness and confirmability of elements contained in ingroup and outgroup stereotypes. The first experiment shows that positive elements of the ingroup stereotype (Italians) and negative elements of the outgroup stereotype (Jews, Germans) tended to be particularly abstract. Also, negative elements contained in the outgroup stereotypes required relatively little evidence to be considered ‘true’ but much disconfirming evidence to be rejected as ‘false’. No such bias emerged for ingroup stereotypes. The second experiment compared the abstraction of four outgroup stereotypes (Jews, Blacks, homosexuals, career women) finding the greatest abstraction for the oldest stereotype (Jews), and least abstraction for the most recent stereotype (career women) with the remaining two groups (Blacks, homosexuals) occupying an intermediate position. Results are interpreted as suggesting that stereotypes may become more abstract over time as they lose the concrete elements that are easier to disconfirm while maintaining the abstract elements that are more resistant to change. © 1998 John Wiley & Sons, Ltd.
The Preparation of Students From National Science Foundation–Funded and Commercially Developed High School Mathematics Curricula for Their First University Mathematics Course

The selection of K–12 mathematics curricula has become a polarizing issue for schools, teachers, parents, and other educators and has raised important questions about the long-term influence of these curricula. This study examined the impact of participation in either a National Science Foundation–funded or commercially developed mathematics curriculum on the difficulty level of the first university mathematics course a student enrolled in and the grade earned in that course. The results provide evidence that National Science Foundation–funded curricula do not prepare students to initially enroll in more difficult university mathematics courses as well as commercially developed curricula, but once enrolled students earn similar grades. These findings have important implications for high school mathematics curriculum selection and for future research in this area.
Adolescents’ risk-taking behavior is driven by tolerance to ambiguity

Adolescents engage in a wide range of risky behaviors that their older peers shun, and at an enormous cost. Despite being older, stronger, and healthier than children, adolescents face twice the risk of mortality and morbidity faced by their younger peers. Are adolescents really risk-seekers or does some richer underlying preference drive their love of the uncertain? To answer that question, we used standard experimental economic methods to assess the attitudes of 65 individuals ranging in age from 12 to 50 toward risk and ambiguity. Perhaps surprisingly, we found that adolescents were, if anything, more averse to clearly stated risks than their older peers. What distinguished adolescents was their willingness to accept ambiguous conditions—situations in which the likelihood of winning and losing is unknown. Though adults find ambiguous monetary lotteries undesirable, adolescents find them tolerable. This finding suggests that the higher level of risk-taking observed among adolescents may reflect a higher tolerance for the unknown. Biologically, such a tolerance may make sense, because it would allow young organisms to take better advantage of learning opportunities; it also suggests that policies that seek to inform adolescents of the risks, costs, and benefits of unexperienced dangerous behaviors may be effective and, when appropriate, could be used to complement policies that limit their experiences.
A test of conditioned blocking and its development in childhood and adolescence : Relationship to personality and monoamine metabolism

Conditioned blocking (CB) is the undermining of conditioning to a stimulus by conjoint exposure with one already associated with the unconditioned stimulus. CB is one of several tests of “learned inattention” in which performance has been found to depend on personality features of human participants and monoamine activity in animals. In Part 1, the performance of 25 healthy young adults on a new test form for demonstrating CB is described. From personality inventories and 24‐hr urine samples it was proposed that CB may be correlated with extroversion and increased catecholamine utilization. In Part 2, CB was shown to be present in 4 groups of 11 participants with mean ages of 10, 14, 17 and 22 years independent of IQ, but it was least marked in the prepubertal group. No relation of performance with personality features was found. As with the adult group, CB was positively correlated with dopamine activity, but unlike the adults it was negatively correlated with noradrenalin activity. The maturation of att.
Two sides to the breakup of dating relationships.

Very few studies on the aftermath of relationship breakups have included data from both ex-partners. The major purpose of this study was to examine whether there is any validity to the principle that there are two sides to every breakup. Questionnaire data were collected from both partners of 47 heterosexual, dating couples after they experienced the breakup of their relationship. Their emotional reactions, perceptions of who had control over the breakup, and perceptions of reasons for the breakup were analyzed. Results indicated that there was no association between ex-partners in the level of distress experienced after the breakup. Ex-partners agreed about who had control and who was responsible for the breakup and about some of the specific reasons for the breakup. Fewer gender differences were found in this study than have been found in previous research on dating relationship breakups (e.g., Hill, Rubin, & Peplau, 1976). For example, men and women were similar in the overall distress they experienced after the breakup and in the reasons they gave for the breakup. Women were more likely than men to be seen as the initiator of the breakup, but only by women themselves. Additional analyses indicated that perceptions of control and the reasons for the breakup were related to emotional reactions after the breakup.
Quest religion and the problem of limited compassion

Is the religious questing orientation an unprejudiced orientation that shows tolerance for people to a degree that suggests universal, rather than circumscribed, compassion? To answer this question, 90 undergraduates were given the opportunity to help either of two peers win a monetary prize. The identity of one of the peers was manipulated across two conditions: he or she was presented as holding a religious fundamentalist belief style or belief style unspecified. The purpose of the monetary prize was also varied across two conditions: an activity that either would or would not promote religious fundamentalist behavior. Participants scoring high in religious questing helped the discloser who held a religious fundamentalist belief style less than the discloser who did not, irrespective of whether they promoted religious fundamentalist behavior or not. These results suggest that the questing orientation is associated with prejudice toward the value-violating person when the salient person value violates the open-minded belief style of the questing orientation.
Alterations of protein glycosylation in embryonic stem cells during adipogenesis

The understanding of adipose tissue development is crucial for the treatment of obesity-related diseases. Adipogenesis has been extensively investigated at the gene and protein levels in recent years. However, the alterations in protein glycosylation during this process remains unknown, particularly that of parthenogenetic embryonic stem cells (pESCs), a type of ESCs with low immunogenicity and no ethical concerns regarding their use. Protein glycosylation markedly affects cell growth and development, cell-to-cell communication, tumour growth and metastasis. In the present study, the adipogenic potentials of J1 ESCs and pESCs were first compared and the results demonstrated that pESCs had lower adipogenic potential compared with J1 ESCs. Lectin microarray was then used to screen the alteration of protein glycosylation during adipogenesis. The results revealed that protein modification of GlcNAc and α-1-2-fucosylation increased, whereas α-1-6-fucosylation, α-2-6-sialylation and α-1-6-mannosylation decreased in J1 ESCs and pESCs during this process. In addition, α-1-3-mannosylation decreased only in pESCs. Lectin histochemistry and quantitative polymerase chain reaction of glycosyltransferase confirmed the results obtained by lectin microarray. Therefore, protein glycosylation of ESCs was significantly altered during adipogenesis, indicating that protein glycosylation analysis is not only helpful for studying the mechanism of adipogenesis, but may also be used as a marker to monitor adipogenic development.
A Decade of Internationalisation

This article considers how student views of collaborative study in a diverse international academic context may have changed in the past decade. A retrospective is provided on a research project carried out in 1998 that investigated students' views of working in international groups; this is linked with research carried out by the author in 2008. Despite the fact that examples of ethnic reductionism remain, there appeared to be a more positive social atmosphere in the 2008 data; students perceived cross-cultural interaction as valuable. Where there were conflicts within groups, these stemmed from clashes over disciplinary variation and differences in ideas about how to get things done. This article provides some suggestions for why there was a more positive working atmosphere between students.
Learning in silicon: A neuromorphic model of the hippocampus

LEARNING IN SILICON: A NEUROMORPHIC MODEL OF THE HIPPOCAMPUS John Vernon Arthur Supervisor: Kwabena Boahen The human brain is the most complex computing structure in the known universe; it excels at many tasks that digital computers perform poorly, such as learning input patterns and later retreiving them with only a part of the original patterns as input, realizing associative memory. Our brains perform these feats rapidly and with unmatched energy efficiency, using only about 10W, far less than a typical light bulb. To explore neurobiological processing, neuromorphic engineers use existing silicon technology to duplicate neural structure and function down to the level of ion channels, efficiently morphing brain-like computation into mixed analog and digital integrated circuits. In this dissertation, we present a neuromorphic model of the hippocampus, a brain region critical in associative memory. We model hippocampal rhythmicity for the first time in a neuromorphic model by developing a new class of silicon neurons that synchronize by using shunting inhibition (conductance-based) with a synaptic rise-time. Synaptic rise-time promotes synchrony by delaying the effect of inhibition, providing an opportune period for neurons to spike together. Shunting inhibition, through its voltage dependence, inhibits neurons that spike out of phase more strongly (delaying the spike further), pushing them into phase (in the next cycle). In addition, we use these neurons to implement associative memory in a recurrent network that uses binary-weighted synpases with spike timing-dependent plasticity (STDP) to
Factors Influencing Attitudes Toward Sexual Activity Among Early Adolescents in Japan

The purpose of this study was to examine factors influencing attitudes toward sexual activity among early adolescents in Japan. A total of 1,551 students aged 12 to 14 years at 4 junior high schools were divided into either a conservative or liberal group. Results of chi-square tests showed that the liberal group had higher percentages of students with drinking, smoking, and sexual activity than the conservative group. The liberal group also had more dating partners and friends with sexual experiences than the conservative group. Unpaired t test indicated that the liberal group rated lower than the conservative group in talking to their parents about life and AIDS and teachers listening to their opinions. Furthermore, a multiple regression analysis showed that smoking, experience with sex, talking to parents about AIDS, teachers listening to participants’ opinion, older dating partners, and friends with sexual experiences were all significant predictors of attitude toward sexual activity.
Effect of testosterone replacement treatment on constitutional and sexual symptoms in type 2 diabetic men: need for rules

In a recent publication, Gianatti and colleagues investigated the effect of testosterone treatment in obese, aging men with type 2 diabetes (T2D) with mild to moderate symptoms, a modest reduction in testosterone levels, mild to moderate aging male symptoms, and erectile dysfunction. [1] The authors could not show any significant improvement in constitutional or sexual symptoms in this group of men. This randomized double-blind, parallel, and placebo-controlled trial among other critically emphasizes the increased testosterone prescriptions worldwide and together with other corroborating or contradictory studies awakes the need for guidelines in the androgen replacement treatment.
Why Have the Leading Journals in Management (and Other Social Sciences) Failed to Respond to Climate Change?

The effect of climate change on business is likely to be substantial. It might be expected, therefore, that the scholarly field of business and management would be centrally engaged with the challenges that global warming will bring. Yet, in this article, the author shows that the most cited management journals have barely published an article on the topic. Similarly, low numbers of articles appear in the prestigious journals in economics, sociology, and political science. Why have the top journals failed to respond? The author proposes five possible explanations. Among these five explanations, the author emphasize the existence of an undesirable delay between ideas appearing first in peripheral publications and then in the elite journals.
WORL: A Web Ontology Rule Language

We develop a Web ontology rule language, called WORL, which combines a variant of OWL 2 RL with eDatalog-with-negation. We disallow the features of OWL 2 RL that play the role of constraints (i.e., the ones that are translated to negative clauses), but allow additional features like negation, the minimal number restriction and unary external checkable predicates to occur in the left hand side of concept inclusion axioms. Some restrictions are adopted to guarantee a translation into eDatalog-with-negation. We also develop the well-founded semantics for WORL and the standard semantics for stratified WORL (SWORL) via translation into eDatalog-with-negation. Both WORL and SWORL have PTime data complexity. In contrast to the existing combined formalisms, in WORL and SWORL negation in concept inclusion axioms is interpreted using nonmonotonic semantics.
Age, Sex, and Attitude toward the past as Predictors of Consumers’ Aesthetic Tastes for Cultural Products

New data pertaining to tastes for popular culture support and extend the previous finding that consumers tend to form enduring preferences during a sensitive period in their lives. A psychographic measure of the consumer's attitude toward the past is shown to moderate this tendency, and differences between male and female respondents suggest that the experience of strong positive feelings plays a causal role. These findings can guide the marketer in designing aesthetic aspects of products or promotional stimuli and may increase the practicality of using cohort analysis for predictions of consumer demand.
