An Approach Towards A Polyphonic Music Retrieval System

Most research on music retrieval systems is based on monophonic musical sequences. In this paper, we investigate techniques for a full polyphonic music retrieval system. A method for indexing polyphonic music data files using the pitch and rhythm dimensions of music information is introduced. Our strategy is to use all combinations of monophonic musical sequences from polyphonic music data. ‘Musical words’ are then obtained using the n-gram approach enabling text retrieval methods to be used for polyphonic music retrieval. Here we extend the n-gram technique to encode rhythmic as well as interval information, using the ratios of onset time differences between two adjacent pairs of pitch events. In studying the precision in which intervals are to be represented, a mapping function is formulated in dividing intervals into smaller classes. To overcome the quantisation problems that arise with using rhythmic information from performance data, an encoding mechanism using ratio bins is also adopted. We present results from retrieval experiments with a database of 3096 polyphonic pieces.

Efficient Quantum Transforms

Quantum mechanics requires the operation of quantum computers to be unitary, and thus makes it important to have general techniques for developing fast quantum algorithms for computing unitary transforms. A quantum routine for computing a generalized Kronecker product is given. Applications include re-development of the networks for computing the Walsh-Hadamard and the quantum Fourier transform. New networks for two wavelet transforms are given. Quantum computation of Fourier transforms for non-Abelian groups is defined. A slightly relaxed definition is shown to simplify the analysis and the networks that computes the transforms. Efficient networks for computing such transforms for a class of metacyclic groups are introduced. A novel network for computing a Fourier transform for a group used in quantum errorcorrection is also given.
Meeting Today's Governance Challenges

The Journal of Higher Education, Vol. 75, No. 4 (July/August 2004) Copyright © 2004 by The Ohio State University Over the past four decades higher education institutions have faced increasing complexity related to governance (Berdahl, 1991; Birnbaum, 1988; Kezar, 2000; Leslie & Fretwell, 1996). In particular, institutions now face even greater competing priorities and demands to engage the community, business, and industry; to solve social problems and improve the schools; to generate cutting edge research and innovations to fuel the economy; to develop a more just and equal society by preparing a diverse student body, while having fewer funds, more demands from students, and an increasingly complex legal environment (Eckel, Hill, & Green, 1998; Kezar, 2000). Three significant changes in the environment within the last decade make governance even more problematic and will be described in greater detail in this article: (1) the need to respond to diverse environmental issues, such as accountability and competition; (2) weak mechanisms for faculty participation, major faculty retirement with close to half of the faculty retiring in the next ten years and a more diverse faculty entering the professoriate; and (3) the need to respond more efficiently based on shorter decision time frames (Kezar, 2000). The intense environmental demands on higher education place great responsibility and strain on institutional leaders to make wise decisions in a timely manner. Dill and Helm (1988) argue that “the substance of academic governance has changed” (p. 323). They note that traditional “maintenance” decisions, which include items such as the allocation of Meeting Today’s Governance Challenges
Constituency pressures on committee selection: Evidence from the Northern Ireland Assembly and Dáil Éireann

Most previous research examining selection to committees assumes constituency pressures—leading representatives to seek committee assignments dealing with their constituents’ particularistic interests that improve their re-election prospects—are incompatible with disciplined parties, which may prevent such personal vote-seeking behaviour in order to preserve the party’s brand. In contrast, we argue parties will support committee assignments promoting members’ re-election chances because parties benefit from their members’ re-election. Analysing two legislatures with highly disciplined parties and electoral systems encouraging personal vote-seeking—the Northern Ireland Assembly and Dail Eireann—our analysis suggests constituency pressures increase the chances of selection to committees enhancing members’ re-election prospects.
A behavioral approach to modelling strategy execution: The role of organizational support and the moderated mediation effect of engagement and communication

Much of the failure in strategy execution in organization is attributed to human factors. While there is abundance of studies which delve into strategy execution, literature pertaining to the behavioral strategy and its impact on strategy execution remains scarce. Interest towards behavioral strategy is recently renewed as a result of the rising concern of the non-progressive rate of successful strategy implementation in the practicing world. This study answers the call for more research on behavioral strategy by examining the role of engagement, a concept drawn from the theory of engagement and work-psychology literature, in explaining the support-execution relationship. Subsequently, the support-execution model of strategy execution is advanced by a joint investigation of the mediating role of strategy engagement as well as the moderating role of strategy communication in the mediated relationship. Using PROCESS macro in SPSS, the model was tested with 224 middle level managers selected from the service industry in Malaysia. The result shows that strategy engagement mediates the relationship between organizational support and strategy execution. Moreover, strategy communication is found to moderate the relationship between firstly organizational support and strategy execution, and secondly strategy engagement and strategy execution. The moderated mediation analysis reveals that strategic communication moderates the mediated relationship between organizational support and strategy execution via strategy engagement. Results from the integrated moderated mediation model provide new insights into the interaction of behavioral variables and their effect on strategy execution in contemporary business environment.

‘Do you want this?’ Exploring newcomer migrant girls’ peer reception in Norwegian day care: Experiences with social exclusion through the exchange of self-made artefacts

This article approaches newcomer migrant girls’ experiences with social competition and relational aggression. This the authors do through a detailed analysis of the interactional practices that a group of preschool-aged girls make use of as they socially exclude one of two newcomer migrant girls from participating in a sharing activity involving self-made artefacts. The data is drawn from ethnography combined with video recordings of natural and situated activities of the girls’ interactions in a Norwegian day-care institution over the course of nine months. Combining structural and social-constructivist perspectives, the authors discuss how a day-care group is a social field comprising multiple subfields characterized by agents struggling over position and power. Overall, this article addresses another side of the generally accepted positive view of day care for migrant children, revealing how relational aggression might be embedded within seemingly harmless activities and set in everyday child-governed activities. Finally, the authors reflect on implications for pedagogical practices and make suggestions for future research.
Cellular traffic offloading onto network-assisted device-to-device connections

While operators have finally started to deploy fourth generation broadband technology, many believe it will still be insufficient to meet the anticipated demand in mobile traffic over the coming years. Generally, the natural way to cope with traffic acceleration is to reduce cell size, and this can be done in many ways. The most obvious method is via picocells, but this requires additional CAPEX and OPEX investment to install and manage these new base stations. Another approach, which avoids this additional CAPEX/OPEX, involves offloading cellular traffic onto direct D2D connections whenever the users involved are in proximity. Given that most client devices are capable of establishing concurrent cellular and WiFi connections today, we expect the majority of immediate gains from this approach to come from the use of the unlicensed bands.
X-ray Spectroscopy of the Cluster of Galaxies Abell 1795 with XMM-Newton

The initial results from XMM-Newton observations of the rich cluster of galaxies Abell 1795 are presented. The spatially-resolved X-ray spectra taken by the European Photon Imaging Cameras (EPIC) show a temperature drop at a radius of $\sim 200$ kpc from the cluster center, indicating that the ICM is cooling. Both the EPIC and the Reflection Grating Spectrometers (RGS) spectra extracted from the cluster center can be described by an isothermal model with a temperature of $\sim 4$ keV. The volume emission measure of any cool component ($<1$ keV) is less than a few % of the hot component at the cluster center. A strong OVIII Lyman-alpha line was detected with the RGS from the cluster core. The O abundance and its ratio to Fe at the cluster center is 0.2--0.5 and 0.5--1.5 times the solar value, respectively.
Endogenous interferon- (cid:1) is required for efﬁcient skeletal muscle regeneration

Endogenous interferon- (cid:1) is required for efﬁcient skeletal muscle regeneration. inﬂammatory response is thought to play important roles in tissue healing. The hypothesis of this study was that the inﬂammatory cytokine interferon (IFN)- (cid:1) is produced endogenously following skeletal muscle injury and promotes efﬁcient healing. We show that IFN- (cid:1) is expressed at both mRNA and protein levels in skeletal muscle following injury, and that the time course of IFN- (cid:1) expression correlated with the accumulation of macrophages, T-cells, and natural killer cells, as well as myoblasts, in damaged muscle. Cells of each type were isolated from injured muscle, and IFN- (cid:1) expression was detected in each cell type. We also demonstrate that administration of an IFN- (cid:1) receptor blocking antibody to wild-type mice impaired induction of interferon response factor-1, reduced cell proliferation, and decreased formation of regenerating ﬁbers. IFN- (cid:1) null mice showed similarly impaired muscle healing associated with impaired macrophage function and development of ﬁbrosis. In vitro studies demonstrated that IFN- (cid:1) and its receptor are expressed in the C2C12 muscle cell line, and that the IFN- (cid:1) receptor blocking antibody reduced proliferation and fusion of these muscle cells. In summary, our results indicate that IFN- (cid:1) promotes muscle healing, in part, by stimulating formation of new muscle ﬁbers.
Intercomparison of Evapotranspiration Over the Savannah Volta Basin in West Africa Using Remote Sensing Data

This paper compares evapotranspiration estimates from two complementary satellite sensors – NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and ESA's ENVISAT Advanced Along-Track Scanning Radiometer (AATSR) over the savannah area of the Volta basin in West Africa. This was achieved through solving for evapotranspiration on the basis of the regional energy balance equation, which was computationally-driven by the Surface Energy Balance Algorithm for Land algorithm (SEBAL). The results showed that both sensors are potentially good sources of evapotranspiration estimates over large heterogeneous landscapes. The MODIS sensor measured daily evapotranspiration reasonably well with a strong spatial correlation (R2=0.71) with Landsat ETM+ but underperformed with deviations up to ∼2.0 mm day-1, when compared with local eddy correlation observations and the Penman-Monteith method mainly because of scale mismatch. The AATSR sensor produced much poorer correlations (R2=0.13) with Landsat ETM+ and conventional ET methods also because of differences in atmospheric correction and sensor calibration over land.
In Silico Docking to Explicate Interface between Plant-Originated Inhibitors and E6 Oncogenic Protein of Highly Threatening Human Papillomavirus 18

The leading cause of cancer mortality globally amongst the women is due to human papillomavirus (HPV) infection. There is need to explore anti-cancerous drugs against this life-threatening infection. Traditionally, different natural compounds such as withaferin A, artemisinin, ursolic acid, ferulic acid, (-)-epigallocatechin-3-gallate, berberin, resveratrol, jaceosidin, curcumin, gingerol, indol-3-carbinol, and silymarin have been used as hopeful source of cancer treatment. These natural inhibitors have been shown to block HPV infection by different researchers. In the present study, we explored these natural compounds against E6 oncoprotein of high risk HPV18, which is known to inactivate tumor suppressor p53 protein. E6, a high throughput protein model of HPV18, was predicted to anticipate the interaction mechanism of E6 oncoprotein with these natural inhibitors using structure-based drug designing approach. Docking analysis showed the interaction of these natural inhibitors with p53 binding site of E6 protein residues 108-117 (CQKPLNPAEK) and help reinstatement of normal p53 functioning. Further, docking analysis besides helping in silico validations of natural compounds also helped elucidating the molecular mechanism of inhibition of HPV oncoproteins.
Superstars and Mediocrities: Market Failure in the Discovery of Talent

A basic problem facing most labor markets is that workers can neither commit to long-term wage contracts nor can they self …nance the costs of production. I study the eects of these imperfections when talent is industry-speci…c, it can only be revealed on the job, and once learned becomes public information. I show that …rms bid exces- sively for the pool of incumbent workers at the expense of trying out new talent. The workforce is then plagued with an unfavorable selection of individuals: there are too many mediocre workers, whose talent is not high enough to justify them crowding out novice workers with lower expected talent but with more upside potential. The result is an ine¢ ciently low level of output coupled with higher wages for known high talents. This problem is most severe where information about talent is initially very imprecise and the complementary costs of production are high. I argue that high incomes in pro- fessions such as entertainment, management, and entrepreneurship, may be explained by the nature of the talent revelation process, rather than by an underlying scarcity of talent.

Working Papers SOCIAL EVALUATION OF ALTERNATIVE BASIC INCOME SCHEMES IN ITALY

This paper discusses methodological principles for social evaluation of tax systems and tax reforms when the concern is primarily turned to who gains and who loses. The discussion is followed by an empirical analysis based on Italian household data. Using a household microeconometric labor supply model we have simulated behavioral responses and welfare gains and losses for married couples resulting from replacing the Italian tax system as of 1993 by three alternative hypothetical reforms, namely, a flat tax, a negative income tax, and a work fare scheme.
Effects of Renal Sympathetic Denervation on Post-Myocardial Infarction Cardiac Remodeling in Rats

Objective To investigate the therapeutic effects of renal denervation (RD) on post- myocardial infarction (MI) cardiac remodeling in rats, the most optimal time for intervention and the sustainability of these effects. Methods One hundred SPF male Wistar rats were randomly assigned to N group (Normal, n = 10), MI group(MI, n = 20),RD group (RD, n = 10), RD3+MI (MI three days after RD, n = 20), MI1+RD (RD one day after MI, n = 20), MI7+RD (RD seven days after MI, n = 20). MI was produced through thoracotomic ligation of the anterior descending artery. RD was performed through laparotomic stripping of the renal arteriovenous adventitial sympathetic nerve. Left ventricular function, hemodynamics, plasma BNP, urine volume, urine sodium excretion and other indicators were measured four weeks after MI. Results (1) The left ventricular function of the MI group significantly declined (EF<40%), plasma BNP was elevated, urine output was significantly reduced, and 24-hour urine sodium excretion was significantly reduced. (2) Denervation can be achieved by surgically stripping the arteriovenous adventitia, approximately 3 mm from the abdominal aorta. (3) In rats with RD3+MI, MI1+RD and MI7+RD, compared with MI rats respectively, the LVEF was significantly improved (75±8.4%,69±3.8%,73±5.5%), hemodynamic indicators were significantly improved, plasma BNP was significantly decreased, and the urine output was significantly increased (21.3±5 ml,23.8±5.4 ml,25.2±8.7 ml). However, the urinary sodium excretion also increased but without significant difference. Conclusions RD has preventive and therapeutic effects on post-MI cardiac remodeling.These effects can be sustained for at least four weeks, but there were no significant differences between denervation procedures performed at different times in the course of illness. Cardiac function, hemodynamics, urine volume and urine sodium excretion in normal rats were not affected by RD.
Development of Attentional Allocation

Top-down control over attention was investigated on a dual task in 10-year-olds (N = 15) and adults (N = 21). The tasks were an auditory Digit Span and a simple visual Response Time task. In four conditions, participants performed neither (no-task), one (Digit Span or Response Time only), or both tasks (dual). Dependent variables were Digit Span accuracy, response time, and pupillary dilation to digits as an estimate of mental effort. Children’s behavioral and psychophysiological responses as a function of sequence length and stimulus position were generally similar to those of adults. Slopes of the functions relating pupillary dilation to memory load were linear and increasing in both groups; shallower in dual than in Digit Span only; and shallower in children than adults. Children’s behavioral results on the Digit Span task began to diverge from those of adults as task demands shifted from passive retention to active rehearsal, but the children did not appear to try harder to compensate for a lower level of behavioral performance. Taken together, the findings suggest that although children allocated their attention in a similar manner as adults, their top-down control over attention in accordance with task difficulty was not yet fully mature.
Effects of purpose of appraisal on leniency errors: An exploration of self-efficacy as a mediating variable

The purpose of this study was to explore the causal relationship between purpose of appraisal and leniency in performance ratings. A model in which rater self-efficacy mediated the relationship between appraisal purpose and leniency was tested. In addition, behavioral recognition accuracy was hypothesized to affect rater leniency. In a laboratory setting, 109 undergraduate raters judged the videotaped performance of a graduate teaching assistant. Results of the study showed that (a) leniency was positively related to task-specific self-efficacy, and (b) behavioral recognition accuracy was positively related to general rating self-efficacy. A purpose of appraisal effect was not observed and the proposed mediational model was not supported. These results were discussed in relation to rater affect, accountability in performance ratings, and information processing. Introduction The errors associated with performance evaluations are a major concern in both academic and industrial organizations "because the actions based on the information from the rating process have critical implications for both the individual and the organization" (Lee, 1985, p. 322). Information provided by performance appraisals may be applied to many managerial functions such as: personnel training, wage and salary administration, placement, promotions, and personnel research (Murphy & Cleveland, 1995). Performance appraisal information also has uses associated with federal law on fair employment practices. The need for accurate performance measures is essential to the successful management of human labor (Bretz, Milkovich, & Read, 1990). Despite the importance of performance measures, their validity is compromised by inaccuracies such as leniency. Research on performance appraisal has indicated that the purpose of rating has an effect on the severity of leniency errors (e.g. perhaps the relationship between purpose of appraisal and leniency error is only part of a more complex model. Research has neglected to explore the possibility that the relationship between purpose of appraisal and rating accuracy may be mediated (Baron & Kenny, 1986) by a third variable. Landy & Farr (1980) suggested that the purpose of rating is one of a number of situational or contextual variables that affects the evaluation of performance. Their review of performance rating research yielded inconsistent results surrounding the connection between demographic variables (i.e., rater sex) and rating effectiveness. Landy & Farr concluded that cognitive process research (i.e., cognitive complexity) held the most promise for understanding the performance appraisal process. However, 20 years of cognitive research has not shed much light on performance appraisal. Cognitive processes in performance appraisal have been explored concerning rating …
