Application of deep belief networks in eeg-based dynamic music-emotion recognition

Estimating emotional states in music listening based on electroencephalogram (EEG) has been capturing the attention of researchers in the past decade. Although deep belief network (DBN) has witnessed the success in various domains including early works in emotion recognition based on EEG, it remains unclear whether DBN could improve emotion classification in music domains, especially in dynamic strategy that considers time-varying characteristics of emotion. This paper presents an early study of applying DBNs to improve emotion recognition in music listening where emotions were annotated continuously in time by subjects. Our subject-dependent results using stratified 10-fold cross-validation strategy suggested that DBNs could improve performance in valence classification with fractal dimension (FD), power spectral density (PSD), and discrete wavelet transform (DWT) features and improve performance in arousal classification with FD and DWT features. Furthermore, we found that the size of sliding window affected classification accuracies when using features in time (FD) and time-frequency (DWT) domains, while smaller window (1-4 seconds) could achieve higher performance compared with a larger window (5-8 seconds).
Assessing polar bear (Ursus maritimus) population structure in the Hudson Bay region using SNPs

Abstract Defining subpopulations using genetics has traditionally used data from microsatellite markers to investigate population structure; however, single‐nucleotide polymorphisms (SNPs) have emerged as a tool for detection of fine‐scale structure. In Hudson Bay, Canada, three polar bear (Ursus maritimus) subpopulations (Foxe Basin (FB), Southern Hudson Bay (SH), and Western Hudson Bay (WH)) have been delineated based on mark–recapture studies, radiotelemetry and satellite telemetry, return of marked animals in the subsistence harvest, and population genetics using microsatellites. We used SNPs to detect fine‐scale population structure in polar bears from the Hudson Bay region and compared our results to the current designations using 414 individuals genotyped at 2,603 SNPs. Analyses based on discriminant analysis of principal components (DAPC) and STRUCTURE support the presence of four genetic clusters: (i) Western—including individuals sampled in WH, SH (excluding Akimiski Island in James Bay), and southern FB (south of Southampton Island); (ii) Northern—individuals sampled in northern FB (Baffin Island) and Davis Strait (DS) (Labrador coast); (iii) Southeast—individuals from SH (Akimiski Island in James Bay); and (iv) Northeast—individuals from DS (Baffin Island). Population structure differed from microsatellite studies and current management designations demonstrating the value of using SNPs for fine‐scale population delineation in polar bears.
The moderating effect of religiosity on ethical behavioural intentions: An application of the extended theory of planned behaviour to Pakistani bank employees

Purpose The purpose of this paper is to investigate Pakistani bank front-line employees’ intentions to behave ethically by using the extended theory of planned behaviour (ETPB) into which religiosity (i.e. religious activity, devotion to rituals and belief in doctrine) is integrated as a moderating variable. Design/methodology/approach The authors collected 234 self-administered questionnaires and analysed them using SmartPLS 2.0, a second generation structural equation modelling technique. Findings This paper demonstrates that the ETPB can explain intentions to behave ethically. Moral norms (i.e. the rules of morality that people believe they ought to follow) and perceived behavioural control (i.e. people’s perceptions of their ability to perform a given behaviour) are the best predictors of ethical behavioural intentions. The effects of injunctive norms (i.e. perceptions of which behaviours are typically approved or disapproved in an organisation) and of perceived behavioural control on behavioural intent are moderated by religiosity. Practical implications Leading by example, providing ethics training, empowering employees and encouraging the expression of religiosity are proposed as ways to foster an ethical culture in the workplace. Originality/value Even though numerous empirical studies have utilised variants of the theory of planned behaviour to explain consumer behaviour, its applicability to ethical behaviour in the workplace has scarcely been explored. Moreover, its tests in non-western contexts are scant. This study demonstrates the applicability of the ETPB in a broader circumstantial and cultural context and enriches it with religiosity, a pertinent characteristic of billions of people around the world. Finally, this is one of the very few ethics studies focusing on banking, an industry fraught with allegations of moral breaches.
Natural Hazards and Earth System Sciences Tornadoes and waterspouts in Catalonia ( 1950 – 2009 )

This paper presents a preliminary climatology of tornadoes and waterspouts in Catalonia (NE Iberian Peninsula). A database spanning 60 yr (1950–2009) has been developed on the basis of information collected from various sources such as weather reports, insurance companies, newspapers and damage surveys. This database has been subjected to a rigorous validation process, and the climatology describes its main features: timing, spatial pattern, and trends in the tornado and waterspout distribution. Results show the highest concentration of tornadoes from August to October, the highest density in the heavily populated coastal areas and a growing positive trend that is likely more closely linked to an increase in observation and perception rather than a real climatic trend.
Differential Microenvironment Localization of Effector and Memory CD8 T Cells1

CD8 T cells are critical for the clearance of intracellular pathogens. Upon infection, naive CD8 T cells differentiate into effector cells that target and eliminate infected cells. Following clearance of the pathogen, most effector cells die, although a small fraction survives to establish a memory population. Subsequent exposure to the same pathogen induces a rapid response of memory T cells and efficient elimination of the pathogen. Although much is known about the CD8 T cell response, the precise microenvironment location of effector and memory CD8 T cells in secondary lymphoid organs is not well characterized. In this study, we present an in situ analysis of the localization of effector and memory CD8 T cells during the murine immune response to lymphocytic choriomenginits virus. We identified the location of these cells using a transgenic mouse model system in which CD8 T cells are irreversibly tagged with yellow fluorescent protein (YFP) after activation. After infection, YFP+ CD8 T cells were initially observed within T cell zones. Later, these cells were found in the red pulp and a disruption of all CD8 T cell zones was observed. After resolution of the immune response, YFP+ memory CD8 T cells were observed primarily in T cells zones. Thus, in the spleens of mice, effector CD8 T cells localize to the red pulp and memory CD8 T cells localize to the T cell zones. Upon rechallenge, memory CD8 T cells rapidly proliferate and the secondary effector CD8 T cells are found in the red pulp.
Application of Grey Relational Analysis to Determine Key Factors for Investment of Overseas Branch by Logistics Industry ─ U . S . Market as an Example

The business opportunity and scale of American logistics market are important to global logistics operators. Logistics operators in Taiwan are facing the unavoidable question of establishing multinational logistics organizations and strengthening the strategic operational planning in line with international practice. Thus, they will encounter opportunities and challenges when expanding their scale and marching into American market. Meanwhile, unfamiliarity with new market and adoption of inappropriate strategy will deteriorate their performance. When Taiwanese logistics operators invest in American logistics market to expand their scale, they are bound to encounter difficulties and challenges. These possible difficulties and challenges can be identified through interview with high-profile executives from American logistics companies. This paper looks for key factors for entry into American market through grey relational analysis to enable logistics operators to penetrate a new market rapidly, provide services in conformity to local demand or rapidly respond to trade competition, obtain advantages, expand their scale, and even find new niche markets.
Three Drosophila EXT genes shape morphogen gradients through synthesis of heparan sulfate proteoglycans

The signaling molecules Hedgehog (Hh), Decapentaplegic (Dpp) and Wingless (Wg) function as morphogens and organize wing patterning in Drosophila. In the screen for mutations that alter the morphogen activity, we identified novel mutants of two Drosophila genes, sister of tout-velu (sotv) and brother of tout-velu (botv), and new alleles of toutvelu (ttv). The encoded proteins of these genes belong to an EXT family of proteins that have or are closely related to glycosyltransferase activities required for biosynthesis of heparan sulfate proteoglycans (HSPGs). Mutation in any of these genes impaired biosynthesis of HSPGs in vivo, indicating that, despite their structural similarity, they are not redundant in the HSPG biosynthesis. Protein levels and signaling activities of Hh, Dpp and Wg were reduced in the cells mutant for any of these EXT genes to a various degree, Wg signaling being the least sensitive. Moreover, all three morphogens were accumulated in the front of EXT mutant cells, suggesting that these morphogens require HSPGs to move efficiently. In contrast to previous reports that ttv is involved exclusively in Hh signaling, we found that ttv mutations also affected Dpp and Wg. These data led us to conclude that each of three EXT genes studied contribute to Hh, Dpp and Wg morphogen signaling. We propose that HSPGs facilitate the spreading of morphogens and therefore, function to generate morphogen concentration gradients.
Myosin VI Steps via a Hand-over-Hand Mechanism with Its Lever Arm Undergoing Fluctuations when Attached to Actin*

Myosin VI is a reverse direction myosin motor that, as a dimer, moves processively on actin with an average center-of-mass movement of ∼30 nm for each step. We labeled myosin VI with a single fluorophore on either its motor domain or on the distal of two calmodulins (CaMs) located on its putative lever arm. Using a technique called FIONA (fluorescence imaging with one nanometer accuracy), step size was observed with a standard deviation of <1.5 nm, with 0.5-s temporal resolution, and observation times of minutes. Irrespective of probe position, the average step size of a labeled head was ∼60 nm, strongly supporting a hand-over-hand model of motility and ruling out models in which the unique myosin VI insert comes apart. However, the CaM probe displayed large spatial fluctuations (presence of ATP but not ADP or no nucleotide) around the mean position, whereas the motor domain probe did not. This supports a model of myosin VI motility in which the lever arm is either mechanically uncoupled from the motor domain or is undergoing reversible isomerization for part of its motile cycle on actin.
Peers, parents and teachers: A case study on how popular music guitarists perceive support for expertise development from “persons in the shadows”

“Persons in the shadows” may substantially affect how an individual acquires expertise, through, for example, guiding deliberate practice. In the domain of popular music, such persons in the shadows might be peers, parents and teachers. Little research exists on how individuals perceive the impact of persons in the shadows on expertise development, particularly in fields like popular music. This study investigates the perceived impact exerted by peers, parents and teachers on the expertise development of guitarists in the domain of popular music. Interviews were used to investigate nine case studies of guitarists with different expertise levels (experts, sub-experts, amateurs). The main focus was on the roles of “persons in the shadows” concerning practising, learning and motivation. The results show that experts differ from sub-experts and amateurs in the perception of support from persons in the shadows. In particular, peers and the formation of bands were thought of having a strong effect on practising, learning and motivation. The impact of parents and teachers on the expertise development in guitar playing was perceived as more ambiguous, and they were deemed as less important by the expert group.
Interconnect design strategy: structures, repeaters and materials with strategic system performance analysis (S/sup 2/PAL) model

In this paper, we propose a novel methodology for scheming an interconnect strategy, such as what interconnect structure should be taken, how repeaters should be inserted, and when new metal or dielectric materials should be adopted. In the methodology, the strategic system performance analysis model is newly developed as a calculation model that predicts LSI operation frequency and chip size with electrical parameters of transistors and interconnects as well as circuit configuration. The analysis with the model indicates that interconnect delay overcomes circuit block cycle time at a specific length; D/sub c-cross/. Here tentatively, interconnects shorter than D/sub c-cross/ are called local interconnects, and interconnects longer than that as global ones. The cross-sectional structures for local and global tiers are optimized separately. We also calculate global interconnect pitch and the chip size enlarged by the global interconnect pitch and the inserted repeaters, and then estimate the effectiveness of introducing new materials for interconnects and dielectrics.
Community violence exposure, family management practices, and substance use in youth: a cross-cultural study

Associations between community violence exposure, family management practices, and substance use were compared in a sample of early adolescents in low-income communities from the United States (N = 151; M age = 12.71 years, standard deviation = 0.65; 50.3% female) and South Africa (N = 175; M age = 12.55 years, standard deviation = 0.85; 64.6% female) using home interviews with youth and their maternal caregivers. Past year victimization was associated with recent youth substance use. The moderating role of family management practices varied by type of practice (e.g., parental knowledge, control, solicitation, or child disclosure), reporter, and country. High parental knowledge reported by caregiver was protective against substance use only for South African youth. In youth reports, parental knowledge was protective across the United States and South Africa. Youth reports of their disclosure to parents were negatively associated with substance use in the United States but not South Africa. These data highlight the importance of considering both ecological context and reporter in the links between violence exposure, parenting, and substance use in youth.
On network-on-chip comparison

This paper presents the state-of-the-art in the field of network-on-chip (NoC) benchmarking and comparison. The study identifies the mainstream approaches, how NoCs are currently evaluated, and shows which aspects have been covered and those needing more research effort. No single article can cover all the aspects, and therefore, possibility to compare results from various sources must be ensured by proper scientific reporting. Basic guidelines for achieving that are given.
A Novel Target of IscS in Escherichia coli: Participating in DNA Phosphorothioation

Many bacterial species modify their DNA with the addition of sulfur to phosphate groups, a modification known as DNA phosphorothioation. DndA is known to act as a cysteine desulfurase, catalyzing a key biochemical step in phosphorothioation. However, bioinformatic analysis revealed that 19 out of the 31 known dnd gene clusters, contain only four genes (dndB-E), lacking a key cysteine desulfurase corresponding gene. There are multiple cysteine desulfurase genes in Escherichia coli, but which one of them participates into DNA phosphorothioation is unknown. Here, by employing heterologous expression of the Salmonella enterica dnd gene cluster named dptBCDE in three E. coli mutants, each of which lacked a different cysteine desulfurase gene, we show that IscS is the only cysteine desulfurase that collaborates with dptB-E, resulting in DNA phosphorothioation. Using a bacterial two-hybrid system, protein interactions between IscS and DptC, and IscS and DptE were identified. Our findings revealed IscS as a key participant in DNA phosphorothioation and lay the basis for in-depth analysis of the DNA phosphorothioation biochemical pathway.
Knowledge Management in the Learning Economy

The purpose of this paper is to show why to build ‘learning organisations’ must be a central element of knowledge management. The paper argues that the wide use of information technology has a contradictory impact on knowledge management. On the one hand it extends the potential for codifying knowledge. On the other hand it makes tacit knowledge scarcer and it contributes to the formation of ‘a learning economy’. The argument is supported by an empirical analysis of survey data from Denmark showing that firms that introduce several organisational practices, assumed to characterise the learning organisation, are more innovative than the average firm. The paper contributes to the empirical foundation for the argument that learning organisations stimulate innovation and competence building and it makes an original conceptual contribution of practical relevance by linking knowledge management to HRM and innovation management.
Improving the management of iron deficiency in ambulatory heart failure patients

Based on clinical trial data patients with heart failure (HF) and evidence of iron deficiency should be offered intravenous (iv) iron with the aim of improving exercise capacity and symptoms. Baseline measurement in outpatient HF clinics demonstrated that only 50% of patients who may be eligible for iv iron were investigated with iron studies. Our aim was to make sure that 90% of the patients attending our heart failure clinics who were symptomatic and had an ejection fraction (EF) ≤45% should have their iron studies checked within the last six months. In an effort to increase the proportion of suitable patients in whom iron studies are requested, we carried out three plan-do-study-act (PDSA) cycles each with a different intervention. These interventions included a presentation of the clinical trial evidence at a HF multidisciplinary meeting, email reminders prior to clinic and stickers in the patient notes (repeated twice). The effect of each intervention was measured with the outcome being the proportion of eligible patients in whom iron studies were documented within the previous 6 months. The interventions increased the number of suitable patients who had iron studies checked, to as high as 100%, however this effect was not sustained. Root cause analysis revealed that clinicians were unenthusiastic to continue performing iron studies due to inefficiency in the process of admitting patients and giving them iv iron. For example median in-hospital stay of seven hours for an infusion that is given over 15 minutes. In an attempt to improve patient and physician satisfaction we piloted an ambulatory outpatient service to deliver iv iron. We demonstrated that this service was feasible and more efficient as less time was required waiting for a bed or spent in hospital and was less costly. In summary we have demonstrated interventions which can increase the identification of patients who would benefit from iv iron and piloted a new time and cost efficient system of administration of iv iron.
P ARADIGMS FOR S PATIAL AND S PATIO-T EMPORAL D ATA M INING

With some significant exceptions, current applications for data mining are either in those areas for which there is little accepted discovery methodology or are being used within a knowledge discovery process that does not expect authoritative results but finds the discovered rules useful none-the-less. This is in contrast to its application in the fields applicable to spatial or spatio-temporal discovery which possess a rich history of methodological discovery and result evaluation.
An approach to recover feature models from object-oriented source code

Software Product Line (SPL) is a development paradigm that targets the creation of software system variants that belong to the same domain. Usually software system variants, developed with clone-and-own approach, form a starting point for building SPL. To migrate software systems which are deemed similar to a product line, it is necessary to detect the common features and variations between a set of software system variants. Reverse engineering the feature model (FM) of an existing system is a challenging activity. FM describes the common and variable characteristics of a product line. In recent years, a lot of work has addressed the extraction of FM from different artefacts. Little work addressed extraction of FM from source code. This paper proposes a general approach to extract initial FM from the object-oriented (OO) source code of a set of software system variants in order to support the migration process from conventional software development to software product line engineering (SPLE). We present an approach to extract features of FM from the analysis of object-oriented source code for a set of software product variants. This approach is based ﬁrstly on the deﬁnition of the mapping model between object-oriented elements (OOE) and those of FM. Secondly; it uses an identiﬁcation process exploiting on the one hand Formal Concept Analysis (FCA) as a method for clustering OOE corresponding to the implementation of features and on the other hand Latent Semantic Indexing (LSI) to deﬁne a similarity measure on which is based this clustering.
The Effectiveness of Group Play Therapy on Hyperactivity and Attention Deficit Symptoms in School Children

Objective : This study was conducted to explore the effectiveness of group play therapy on decreasing excessive activity and attention deficit in school children. Method : This study was semi-experimental with pre-test, post-test and control group. The Statistical population of this study consisted of all of the elementary school students of Tehran-district 5 who were studying during 2015-2016 school year. This study included 40 individuals who were selected based on availability and randomly assigned to two experiment (n= 20) and control (n= 20) groups. In order to assess the hyperactivity and attention-deficit variable, the fourth revision of the Swanson, Nolan and Pelham Profile (SNAP-IV) of attention deficit and hyperactivity disorder was used. The experiment group participated in 10 sessions of group play therapy during 5 weeks, while the control group received no interventions. The results were analyzed using analysis of covariance (ANCOVA). Results : The results of ANCOVA showed that there was a significant difference between the post-tests of the two groups. Discussion and conclusion : The results showed that group play therapy intervention is effective in decreasing the symptoms of hyperactivity and attention-deficit of school children. Play therapy, along with other therapeutic interventions, can be applied as an intervention rich in constructive and effective relationships which has positive side effects on reducing hyperactivity and attention deficit symptoms of children.
