Scalable Boolean Tensor Factorizations using Random Walks

Tensors are becoming increasingly common in data mining, and consequently, tensor factorizations are becoming more and more important tools for data miners. When the data is binary, it is natural to ask if we can factorize it into binary factors while simultaneously making sure that the reconstructed tensor is still binary. Such factorizations, called Boolean tensor factorizations, can provide improved interpretability and nd Boolean structure that is hard to express using normal factorizations. Unfortunately the algorithms for computing Boolean tensor factorizations do not usually scale well. In this paper we present a novel algorithm for nding Boolean CP and Tucker decompositions of large and sparse binary tensors. In our experimental evaluation we show that our algorithm can handle large tensors and accurately reconstructs the latent Boolean structure.
Boosted Zero-Shot Learning with Semantic Correlation Regularization

We study zero-shot learning (ZSL) as a transfer learning problem, and focus on the two key aspects of ZSL, model effectiveness and model adaptation. For effective modeling, we adopt the boosting strategy to learn a zero-shot classifier from weak models to a strong model. For adaptable knowledge transfer, we devise a Semantic Correlation Regularization (SCR) approach to regularize the boosted model to be consistent with the inter-class semantic correlations. With SCR embedded in the boosting objective, and with a self-controlled sample selection for learning robustness, we propose a unified framework, Boosted Zero-shot classification with Semantic Correlation Regularization (BZ-SCR). By balancing the SCR-regularized boosted model selection and the self-controlled sample selection, BZ-SCR is capable of capturing both discriminative and adaptable feature-to-class semantic alignments, while ensuring the reliability and adaptability of the learned samples. The experiments on two ZSL datasets show the superiority of BZ-SCR over the state-of-the-arts.
“Words with Friends”: Socially Networked Reading on Goodreads

Reading isn't what it was. As we enter the “late age of print,” E-Books are still less common than “P-Books” (printed books), but the balance is quickly changing, especially in the world of academic publishing (Striphas xii). While many lament the loss of the p-book's materiality, texts have become more lively as a result of digitization: textual-production platforms like blogging let writers and readers interact with each other and create intimate social relationships. As Kathleen Fitzpatrick found while writing her book Planned Obsolescence using CommentPress, an online platform that enables readers' commenting, writing can become a more social and creative process when done in dialogue with readers. This turn to the social in writing parallels a turn to the social in media generally. Thus, it makes sense to evaluate not how far our devices are taking us from paper—the answer is already pretty far—but rather how digital media are creating new social valences of reading.
Cache Management for Mobile File Service

File service is a fundamental computing requirement, but one that has been problematic for mobile users. Concerns about the latency associated with transferring large amounts of data over network connections of unknown quality have led to rather ad hoc approaches that provide some functionality, but with uncertain performance. Through a series of trace-driven simulation experiments, we investigate performance issues relating to providing remote le system support to mobile users through optimistic caching at the mobile client. Tradeoos between resources and performance are explored across a variety of design choices, speciically issues relating to system connguration, policies for le system updates (write backs), and choice of caching unit (whole-le caching or block-based caching). The results of our experiments show that it is possible to provide quite acceptable remote le service to weakly connected mobile clients, even when bandwidth is limited. Reads can be serviced in a timely manner, updates can be committed in an acceptable period of time, and resource requirements at the client are modest.
Measuring sensitivity moment-by-moment: A microanalytic look at the transmission of attachment

Meta-analyses have indicated that the mediating power of sensitivity in the transmission of attachment across generations is not nearly as great as would be predicted by attachment theory (van IJzendoorn, 1995; De Wolff & van IJzendoorn, 1997). To make sense of these findings, the author suggests that current measures of sensitivity should be expanded to include the assessment of mother-infant behavior on a micro-behavioral level. This paper reviews evidence for two central propositions: (1) The internal working model of mothers is expressed in subtle, fine-grained interactive behaviors with their infants, and (2) infants perceive and remember these behaviors in the form of interactional expectancies. Following these propositions, hypothesized representational micromodels for each major attachment organization are then offered, based on the Parallel Distributed Processing (PDP) approach to information processing. In closing, this paper presents some of the most pressing unresolved issues for attachment re.
A Simulation Approach to Veritistic Social Epistemology

In a seminal book, Alvin I. Goldman outlines a theory for how to evaluate social practices with respect to their “veritistic value”, i.e., their tendency to promote the acquisition of true beliefs (and impede the acquisition of false beliefs) in society. In the same work, Goldman raises a number of serious worries for his account. Two of them concern the possibility of determining the veritistic value of a practice in a concrete case because (1) we often don't know what beliefs are actually true, and (2) even if we did, the task of determining the veritistic value would be computationally extremely difficult. Neither problem is specific to Goldman's theory and both can be expected to arise for just about any account of veritistic value. It is argued here that the first problem does not pose a serious threat to large classes of interesting practices. The bulk of the paper is devoted to the computational problem, which, it is submitted, can be addressed in promising terms by means of computer simulation. In an attempt to add vividness to this proposal, an up-and-running simulation environment (Laputa) is presented and put to some preliminary tests.
Political Trust in Rural China

This article shows that while some Chinese villagers see the state as monolithic, more believe that there are substantial differences between the central and local governments. Among those who perceive a divided state, most appear to have more trust in higher levels than in lower levels and distinguish between the intent and the capacity of the central government (“the Center”). They trust that the Center’s intent is beneficent but distrust its capacity to ensure faithful implementation of its policies. The article concludes that the central state has some breathing space because dissatisfaction with lower levels does not immediately generate demands for fundamental political reforms; in addition, the combination of trust in the Center’s intent and distrust in its capacity may encourage villagers to defy local officials in the name of the Center. If villagers’ rightful resistance fails, total disillusionment with the Center may set in, resulting in cynicism or radicalism.
Efficient Random-Access Scheme for Massive Connectivity in 3GPP Low-Cost Machine-Type Communications

In order to facilitate low-cost network connection of many devices, machine-type communication (MTC) has evolved to low-cost MTC (LC-MTC) in the third-generation partnership project standard. LC-MTC should be able to effectively handle intensive accesses through multiple narrowband random-access channels (RACHs) assigned within the bandwidth of a long-term evolution system. As the number of MTC devices and their congestion rapidly increase, the random-access scheme for the LC-MTC RACH needs to be improved. This paper presents a novel random-access scheme that introduces virtual preambles of LC-MTC devices and associates them with RACH indexes to effectively discern LC-MTC devices. In comparison with the sole use of preambles, our scheme allows an LC-MTC device to better choose a unique virtual preamble. Thereby, the probability of successful accesses of LC-MTC devices increases in contention-based random-access environments. We experimentally assessed our scheme, and the results show that our scheme performs better than the existing preamble-based scheme in terms of collision probability, access delay, and access blocking probability.
Disentangling effects of uncertainties on population projections: climate change impact on an epixylic bryophyte

Assessment of future ecosystem risks should account for the relevant uncertainty sources. This means accounting for the joint effects of climate variables and using modelling techniques that allow proper treatment of uncertainties. We investigate the influence of three of the IPCC's scenarios of greenhouse gas emissions (special report on emission scenarios (SRES)) on projections of the future abundance of a bryophyte model species. We also compare the relative importance of uncertainty sources on the population projections. The whole chain global climate model (GCM)—regional climate model—population dynamics model is addressed. The uncertainty depends on both natural- and model-related sources, in particular on GCM uncertainty. Ignoring the uncertainties gives an unwarranted impression of confidence in the results. The most likely population development of the bryophyte Buxbaumia viridis towards the end of this century is negative: even with a low-emission scenario, there is more than a 65 per cent risk for the population to be halved. The conclusion of a population decline is valid for all SRES scenarios investigated. Uncertainties are no longer an obstacle, but a mandatory aspect to include in the viability analysis of populations.
Getting Inside the Black Box: Examining How the Operation of Charter Schools Affects Performance

In recent years, a series of articles have examined the performance of charter schools with mixed results. Some of this research has shown that charter school performance varies by charter type or the age of the school (Bifulco & Ladd, 2006; Buddin & Zimmer, 2005; Hanushek, Kain, & Rivkin, 2002; Sass, 2006). However, this research has not examined the school attributes that lead to high- or low-achieving charter schools. In this article, we examine how student achievement varies with school operational features using student-level achievement and survey data for charter and a matched-set of traditional public schools from California. We did not find operational characteristics that were consistently related with student achievement, but we did identify some features that are more important at different grade levels or in charter schools versus in traditional public schools. We also examined the relationship between greater autonomy within schools, which is a major tenet of the charter movement, and student achievement and found very little evidence that greater autonomy leads to improved student achievement.
Examining teachers’ beliefs about ICT in education: implications of a teacher preparation programme

Abstract The survey presented in this article examines current teachers’ beliefs and attitudes towards information and communication technologies (ICT) in education. A total of 1165 primary and secondary education teachers participated in the study, immediately after following a training programme on basic ICT skills. The authors’ results showed that the majority of the teachers in the sample have positive attitudes towards the training programme they attended, the general role that ICT can play in education and the integration of ICT in the educational process. The authors’ findings also revealed some parameters that interfere negatively, thus making many teachers cautious of or sceptical about ICT integration in educational practice. Multivariate analysis identified three groups of teachers that exhibited a consistent approach: a group of teachers having positive attitudes towards the items of the research, a second group with negative attitudes and a third one with neutral beliefs about ICT in education. Moreover, the authors’ analysis extracted significant information on the profile of the teachers within each of the three groups. They found that personal factors (subject matter, teaching experience and gender) are strongly associated with the beliefs and perceptions teachers hold about ICT in education.
Subjective Well-Being in Context

Subjective well-being (SWB) is not only influenced by people’s individual characteristics but also by characteristics of the places where they live. Using data from the Health and Retirement Survey (N = 5,975), we examined whether two indicators of the socioeconomic context (unemployment and poverty rates) are associated with SWB in older adults. The main findings were (a) these contextual variables are differentially related to SWB on the county level and state level in terms of strength and direction, highlighting the importance of distinguishing between different levels of analysis; (b) poverty rate tends to be more strongly associated with life satisfaction and positive affect than with negative affect; and (c) county-level poverty rate is more strongly related to positive affect in poor individuals and county-level unemployment rate is more strongly related to SWB in nonretired individuals, suggesting that the socioeconomic context matters more for people who are directly affected by it.
The Shock of the New: Progress in Schizophrenia Genomics

A growing list of common and rare genetic risk variants are being implicated in schizophrenia susceptibility. As with other complex genetic disorders most of the variance in genetic risk is still to be attributed. What can be learned from progress to date? The available data challenges how we conceptualize schizophrenia and suggests strong aetiological links with other psychiatric and developmental disorders. With the identification of rare copy number risk variants implicating specific genes (e.g. VIPR2 and NRXN1) it is increasingly possible to investigate molecular aetiology in patient subgroups to establish whether schizophrenia represents one or many different disease processes. This review summarizes recent research progress and suggests how the tools of modern genomics and neuroscience can be applied to best understand this devastating disorder.
Competition and Crowding Out in the Market for Outpatient Substance Abuse Treatment

U.S. markets for outpatient substance abuse treatment (OSAT) include for-profit, nonprofit, and public clinics. We study OSAT provision using new methods on equilibrium market structure in differentiated product markets. This allows us to describe clinics as heterogeneous in their objectives, their responses to exogenous market characteristics, and their responses to one another. Consistent with crowding out of private treatment, we find that markets with public clinics are less likely to have private clinics. In markets with low insurance coverage, low incomes, or high shares of nonwhite addicts, however, public clinics are relatively likely to be the sole willing providers of OSAT.
An Equational Specification for the Scheme Language

This work describes the formal semantics of Scheme 3 as an equational theory in the Maude rewriting system. The semantics is based on continuations and is highly modular. We briefly investigate the relationship between our methodology for defining programming languages and other semantic formalisms. We conclude by show- ing some performance results of the interpreter obtained for free from the executable specification.
Impact of 3,4-Dihydroxy-6-18F-Fluoro-l-Phenylalanine PET/CT on Managing Patients with Brain Tumors: The Referring Physician's Perspective

We investigated the impact of 18F-DOPA brain PET/CT on the clinical management of patients with known or suspected brain tumors. Methods: A prospective survey of referring physicians was conducted. A pre-PET questionnaire inquired about indication, tumor histology or grade, level of suspicion for tumor recurrence, and planned management. Early post-PET questionnaires asked referring physicians to categorize PET findings as negative, equivocal, or positive; assessed the level of suspicion for primary or recurrent brain tumor; and recorded intended management changes prompted by PET findings. A late follow-up questionnaire 6 mo after the scan aimed at determining patient outcome (recurrence, survival). In addition, all referring physicians were contacted to determine whether management changes intended after 18F-DOPA PET/CT were implemented. Results: Fifty-eight consecutive patients were included. The clinical suspicion for recurrence increased in 33%, remained unchanged in 50%, and decreased in 17% of patients after adding the PET/CT result to the available diagnostic data. The late post-PET questionnaire confirmed recurrence in 26 patients whereas 32 had stable disease or remained disease-free. 18F-DOPA PET/CT resulted in intended management changes in 41% of patients. Changes in intended management from wait and watch to chemotherapy (6 patients [25%]) and from chemotherapy to wait and watch (4 patients [17%]) occurred most frequently. Clinical follow-up revealed that 75% of intended treatment changes were implemented. Conclusion: 18F-DOPA PET/CT changed the intended management of 41% of patients with brain tumors, and intended management changes were implemented in 75% of these. These changes suggest a potentially important clinical role of imaging amino acid transport in the management of brain tumor patients.
The Administrative Behavior of Federal Bureau Chiefs

Most of the people who keep tabs on the workings of the federal government, no matter what the reasons for their interest, seem to take for granted the power and autonomy of the chiefs of the bureaus that make up the executive branch. Because so much is taken for granted, there have not been many studies of what the chiefs actually do day by day. Of all the participants in the governmental process who wield--or are thought to wield--great influence, bureau chiefs are among the least examined.Believing that he could narrow this gap in the materials on the federal government somewhat, Herbert Kaufman set out to report his observations of six bureau chiefs at their jobs in the course of a year. The group consisted of the commissioners of the Internal Revenue Service, the Customs Service, the Food and Drug Administration, and the Social Security Administration; the chief of the Forest Service; and the administrator of the Animal and Plant Health Inspection Service--a set diversified enough to include a wide variety of organizational situations and experiences, yet with enough in common to allow comparison and generalization.The objective of his research was to describe the chief's activities so as to explain how they exercise their power. And he hoped to find out whether they are as powerful as they are said to be.From his efforts emerges a detailed picture of the work of the bureau leaders and of their role in their agencies and in the government generally. The picture reveals that some of the common beliefs about these officials, and perhaps about the system as a whole, are not altogether accurate. Kaufman traces the implications of his findings for organizing the executive branch, for training administrators, and for organization theory.
Brain and culture : neurobiology, ideology, and social change

Choice Outstanding Academic Title, 2007. Research shows that between birth and early adulthood the brain requires sensory stimulation to develop physically. The nature of the stimulation shapes the connections among neurons that create the neuronal networks necessary for thought and behavior. By changing the cultural environment, each generation shapes the brains of the next. By early adulthood, the neuroplasticity of the brain is greatly reduced, and this leads to a fundamental shift in the relationship between the individual and the environment: during the first part of life, the brain and mind shape themselves to the major recurring features of their environment; by early adulthood, the individual attempts to make the environment conform to the established internal structures of the brain and mind. In Brain and Culture, Bruce Wexler explores the social implications of the close and changing neurobiological relationship between the individual and the environment, with particular attention to the difficulties individuals face in adulthood when the environment changes beyond their ability to maintain the fit between existing internal structure and external reality. These difficulties are evident in bereavement, the meeting of different cultures, the experience of immigrants (in which children of immigrant families are more successful than their parents at the necessary internal transformations), and the phenomenon of interethnic violence. Integrating recent neurobiological research with major experimental findings in cognitive and developmental psychology--with illuminating references to psychoanalysis, literature, anthropology, history, and politics--Wexler presents a wealth of detail to support his arguments. The groundbreaking connections he makes allow for reconceptualization of the effect of cultural change on the brain and provide a new biological base from which to consider such social issues as "culture wars" and ethnic violence.
Anyone for Football for Peace? The challenges of using sport in the service of co‐existence in Israel 1

Football for Peace (F4P) is a joint University of Brighton and British Council initiative that aims to use values‐based football coaching to build bridges between neighbouring Jewish and Arab towns and villages in Israel, and in doing so make a modest contribution to the Peace Process in this most troubled of regions. The work of F4P seeks to make pragmatic and incremental grass‐roots interventions into the sport culture of Israel, helping to build bridges between otherwise divided communities and at the same time make a contribution to political/policy debates around sport in the region. Specifically its fourfold aims are to: provide opportunities for social contact across community boundaries; promote mutual understanding; engender in participants a desire for, and commitment to, peaceful coexistence; and enhance soccer skills and technical knowledge. The following essay overviews the history and development of the project before focussing on the 2005 initiative and the aborted 2006 project.
A novel alignment repulsion algorithm for flocking of multi-agent systems based on the number of neighbours per agent

In this paper, an energy-based control methodology is proposed to satisfy the Reynolds three rules in a flock of multiple agents. First, a control law is provided that is directly derived from the passivity theorem. In the next step, the Number of Neighbours Alignment/Repulsion algorithm is introduced for a flock of agents which loses the cohesion ability and uniformly joint connectivity condition. With this method, each agent tries to follow the agents which escape its neighbourhood by considering the velocity of escape time and number of neighbours. It is mathematically proved that the motion of multiple agents converges to a rigid and uncrowded flock if the group is jointly connected just for an instant. Moreover, the conditions for collision avoidance are guaranteed during the entire process. Finally, simulation results are presented to show the effectiveness of the proposed methodology.
