Can You Spot the Fakes?: On the Limitations of User Feedback in Online Social Networks

Online social networks (OSNs) are appealing platforms for spammers and fraudsters, who typically use fake or compromised accounts to connect with and defraud real users. To combat such abuse, OSNs allow users to report fraudulent profiles or activity. The OSN can then use reporting data to review and/or limit activity of reported accounts. Previous authors have suggested that an OSN can augment its takedown algorithms by identifying a "trusted set" of users whose reports are weighted more heavily in the disposition of flagged accounts. Such identification would allow the OSN to improve both speed and accuracy of fake account detection and thus reduce the impact of spam on users. In this work we provide the first public, data-driven assessment of whether the above assumption is true: are some users better at reporting than others? Specifically, is reporting skill both measurable, i.e., possible to distinguish from random guessing; and repeatable, i.e., persistent over repeated sampling? Our main contributions are to develop a statistical framework that describes these properties and to apply this framework to data from LinkedIn, the professional social network. Our data includes member reports of fake profiles as well as the more voluminous, albeit weaker, signal of member responses to connection requests. We find that members demonstrating measurable, repeatable skill in identifying fake profiles do exist but are rare: at most 2.4% of those reporting fakes and at most 1.3% of those rejecting connection requests. We conclude that any reliable "trusted set" of members will be too small to have noticeable impact on spam metrics.
Chinese students and higher education destinations: Findings from a choice experiment

This paper presents a novel application of a discrete choice experiment that seeks to contribute to a more accurate understanding of international education flows. The discrete choice experiment method is employed to identify the key factors underlying students’ international education choices. The specific focus in the study is on China as the largest origin country of international students in the growing global education market. Data are collected from a sample of prospective Chinese outbound students. The findings suggest that university ranking and destination safety are key decision drivers for Chinese students. The results have policy implications for Australia, as one of the key higher education destination countries, for instance, in relation to recently changed student visa systems and the potential effects of planned government budget cuts to higher education on educational quality and reputation.
Distributed Suboptimal Schemes for TAS/SC and TAS/LS in Fixed-Gain AF Relaying Systems

We design and analyze two distributed suboptimal schemes for transmit-antenna selection and link selection in a dual-hop, fixed-gain, amplify-and-forward relaying system, composed by one multi-antenna source, one single-antenna destination, and one single-antenna relay. The proposed schemes share the same antenna-selection policy, but differ from each other in the way the direct or relaying link is selected for communication. In a first scheme, the link is selected after transmission, at the destination; in a second scheme, it is selected before transmission, at the source. A great advantage of the proposed schemes over the optimal centralized solution is their low and constant delay/feedback overhead, regardless of the number of transmit antennas. In addition, the second scheme brings an improved spectral efficiency, once it saves one time slot when selecting the direct link. We derive analytical lower and upper bounds for the outage probability of the first scheme, in single-fold integral form, and exact closed-form expressions for the outage probability and mean spectral efficiency of the second scheme. We also perform an asymptotic analysis, showing that the first scheme achieves full diversity order, whereas the second scheme achieves full diversity order minus one, as a penalty for its improved spectral efficiency.
In search of the blue flower? Grand social theories and career research: The case of Bourdieu’s theory of practice

Responding to the various calls for more interdisciplinarity in career research over the last few decades, we identify five touchstones for theoretical concepts to advance the interdisciplinary dialogue on careers. Drawing on Bourdieu’s theory of practice, we outline its contributions to such a dialogue in the light of these touchstones. In spite of some potential pitfalls, the theory of practice not only invites interdisciplinary dialogue, but also provides a unifying framework for generating new questions in career research and systematically integrating concepts from other disciplines. Overall, this is but one example of how grand social theories can stimulate interdisciplinarity in career research.
Estimating Risks of Identification Disclosure in Partially Synthetic Data

To limit disclosures, statistical agencies and other data disseminators can release partially synthetic, public use microdata sets. These comprise the units originally surveyed; but some collected values, for example, sensitive values at high risk of disclosure or values of key identifiers, are replaced with multiple draws from statistical models. Because the original records are on the file, there remain risks of identifications. In this paper, we describe how to evaluate identification disclosure risks in partially synthetic data, accounting for released information from the multiple datasets, the model used to generate synthetic values, and the approach used to select values to synthesize. We illustrate the computations using the Survey of Youths in Custody.
Regional Decline of Coral Cover in the Indo-Pacific: Timing, Extent, and Subregional Comparisons

Background A number of factors have recently caused mass coral mortality events in all of the world's tropical oceans. However, little is known about the timing, rate or spatial variability of the loss of reef-building corals, especially in the Indo-Pacific, which contains 75% of the world's coral reefs. Methodology/Principle Findings We compiled and analyzed a coral cover database of 6001 quantitative surveys of 2667 Indo-Pacific coral reefs performed between 1968 and 2004. Surveys conducted during 2003 indicated that coral cover averaged only 22.1% (95% CI: 20.7, 23.4) and just 7 of 390 reefs surveyed that year had coral cover >60%. Estimated yearly coral cover loss based on annually pooled survey data was approximately 1% over the last twenty years and 2% between 1997 and 2003 (or 3,168 km2 per year). The annual loss based on repeated measures regression analysis of a subset of reefs that were monitored for multiple years from 1997 to 2004 was 0.72 % (n = 476 reefs, 95% CI: 0.36, 1.08). Conclusions/Significance The rate and extent of coral loss in the Indo-Pacific are greater than expected. Coral cover was also surprisingly uniform among subregions and declined decades earlier than previously assumed, even on some of the Pacific's most intensely managed reefs. These results have significant implications for policy makers and resource managers as they search for successful models to reverse coral loss.
Focused SAR Image Formation of Moving Targets Based on Doppler Parameter Estimation

This paper addresses the problem of focusing moving targets in synthetic aperture radar (SAR) images. This task is solved here by using an inverse SAR (ISAR) technique. The ISAR technique performs an autofocus procedure by implementing exhaustive search algorithms, which are improved by classical convex optimization, of functions based on image contrast or entropy. In this paper, we discuss the possibility to perform an autofocus ISAR technique by exploiting the estimation of the target Doppler parameters, namely the Doppler centroid and the Doppler rate, which are related to the target motion parameters. The present algorithm is based on the reuse of efficient autofocus approaches that are classically used in direct SAR imaging. The effectiveness of the proposed method is tested on COSMO-SkyMed Spotlight SAR data of maritime targets. Furthermore, the proposed Doppler parameter estimation algorithm is compared with a well-known ISAR technique, namely the image-contrast-based technique.
The Moral Ends of Band

This article provides a theoretical framework through which to reimagine and revitalize contemporary music education practices, using the large ensemble paradigm called band as the primary unit of analysis. Literature suggests that band places too much emphasis on teacher control and external measures of validation. Critics propose replacing this historic art form with ones that exist outside of school. It is argued in this article that band's crisis of legitimacy can be resolved by refocusing on student welfare and student well-being. Because band is the only indigenous American art form that exists in and has come into fruition through the public school, band directors are bound by a public trust to put the education of students first. Using Dewey's understanding of the role of public schooling in a democracy, a vision of moral education through music education is advanced. Band is ideally poised to illustrate what moral education can be.
Spontaneous Inferences from Cultural Cues: Varying Responses of Cultural Insiders and Outsiders

Results from two groups of biculturals (Hong Kong undergraduates, Chinese Americans) and a group of European Americans in two studies showed that in the presence of applicable cues of a culture, individuals with expert knowledge in the culture spontaneously make inferences about the culture's moral values, producing a Stroop-like effect. Although both biculturals and European Americans made spontaneous cultural inferences from American cultural cues, only biculturals made spontaneous inferences from Chinese cultural cues. Moreover, American-Chinese bicultural individuals can switch between correspondent cultural inferences from American and Chinese cultural cues numerous times within one experimental session. Implications on cultural adaptation and cultural competence are discussed.
Meaningfulness in Work in Brazilian and French Creative Industries

Abstract This study aimed to investigate the meaningfulness that Brazilian and French artists find in their work, considering the historic French cultural influence in the Brazilian creative industry. The specific objective was to cross-culturally validate a model of meaningfulness in work that was developed in French Canada and that includes five latent variables: learning and development, utility of work, quality of working relationships, autonomy, and moral correctness. The present study used a French Canadian measurement instrument that was developed for the health care and management occupations in Quebec. A total of 648 individuals, 280 in France and 368 in Brazil, provided online responses that were then analyzed using Confirmatory Factor Analysis (CFA) and Multigroup Confirmatory Factor Analysis (MGCFA). The five–factor structure of the meaningfulness in work model was found to be similar for the two samples of artists—although this model was a better fit to the data for the Brazilian creative professionals than the data for their French counterparts. The analyses showed that the two groups understand the structure of the meaningfulness factors in a similar manner (configural and metric invariance). The study also showed that conceived as a social and economic core activity, work is present in the context of the arts as well as in the traditional sectors of the economy for which the model was developed.
Ankyrin G Expression Regulates Apical Delivery of the Epithelial Sodium Channel (ENaC)*

The epithelial sodium channel (ENaC) is the limiting entry point for Na+ reabsorption in the distal kidney nephron and is regulated by numerous hormones, including the mineralocorticoid hormone aldosterone. Previously we identified ankyrin G (AnkG), a cytoskeletal protein involved in vesicular transport, as a novel aldosterone-induced protein that can alter Na+ transport in mouse cortical collecting duct cells. However, the mechanisms underlying AnkG regulation of Na+ transport were unknown. Here we report that AnkG expression directly regulates Na+ transport by altering ENaC activity in the apical membrane. Increasing AnkG expression increased ENaC activity while depleting AnkG reduced ENaC-mediated Na+ transport. These changes were due to a change in ENaC directly rather than through alterations to the Na+ driving force created by Na+/K+-ATPase. Using a constitutively open mutant of ENaC, we demonstrate that the augmentation of Na+ transport is caused predominantly by increasing the number of ENaCs at the surface. To determine the mechanism of AnkG action on ENaC surface number, changes in rates of internalization, recycling, and membrane delivery were investigated. AnkG did not alter ENaC delivery to the membrane from biosynthetic pathways or removal by endocytosis. However, AnkG did alter ENaC insertion from constitutive recycling pathways. These findings provide a mechanism to account for the role of AnkG in the regulation of Na+ transport in the distal kidney nephron.
Behavior Problems in School and Their Educational Correlates Among Children With Traumatic Brain Injury

This study examined the emotional and behavioral adjustment of children with traumatic brain injury (TBI) in school and its relationship to postinjury academic performance and educational interventions. Teachers' ratings of child behavior and academic performance were collected during a prospective, longitudinal study of 53 children with severe TBI, 56 with moderate TBI, and 80 with orthopedic injuries, recruited between 6 and 12 years of age. Teachers completed ratings twice during the first year after injury and at an extended follow-up 4 years postinjury. Severe TBI was associated with an elevated rate of emotional and behavioral problems that persisted across time. Poorer adjustment predicted poorer classroom performance and an increased likelihood of educational intervention.
Physics-based large-signal sensitivity analysis of microwave circuits using technological parametric sensitivity from multidimensional semiconductor device models

The authors present an efficient approach to evaluate the large-signal (LS) parametric sensitivity of active semiconductor devices under quasi-periodic operation through accurate, multidimensional physics-based models. The proposed technique exploits efficient intermediate mathematical models to perform the link between physics-based analysis and circuit-oriented simulations, and only requires the evaluation of dc and ac small-signal (dc charge) sensitivities under general quasi-static conditions. To illustrate the technique, the authors discuss examples of sensitivity evaluation, statistical analysis, and doping profile optimization of an implanted MESFET to minimize intermodulation which makes use of LS parametric sensitivities under two-tone excitation.
Benjamin S. Bloom's Contributions to Curriculum, Instruction, and School Learning.

Few individuals in the history of education have had greater impact on education policy and practice than Benjamin S. Bloom. During a career that spanned more than 5 decades, his research and writing guided the development of many educational programs and provided insights into the untapped potential of educators to have all students learn well. Bloom's contributions to education began during his years in the Office of the Board of Examiners at the University of Chicago, where he worked from 1940 to 1959. Much of his work at this time focused on the relationships among methods of instruction, educational outcomes, and measurement of those outcomes. This work led to his first book in 1950 and eventually to the work for which he is best known, the "Taxonomy of Educational Objectives, Handbook I: The Cognitive Domain. " In 1959 Bloom spent a year at the Center for Advanced Study in Behavioral Sciences at Stanford University. This year marked a shift in high research and writing, as Bloom began to concentrate on problems in learning, rather than problems in testing, measurement, and evaluation. Bloom's most notable contribution to teaching and learning was his work in developing the theory and practice of mastery learning. Mastery learning was developed as a way for teachers to provide higher quality and more appropriate instruction for their students. Mastery learning depends on feedback, correctives, and enrichments, combined with another essential element of mastery learning, congruence among instructional components. Mastery learning is not an educational panacea, but careful attention to the essential elements of mastery learning will allow educators at all levels to make great strides toward the goal of all children learning excellently.

Anger and economic rationality

This paper evaluates the rationality of anger in the light of a standard notion of economic rationality. Whether anger is rational or otherwise cannot be answered in general, but will depend on the economic setting. As long as anger can be explained as a preference in a parsimonious and stable utility function, it does not make sense to talk of anger as rational or irrational. The production of anger is subtly mediated by many cognitive factors. These (and the anger‐induced cognitive effects and intertemporal inconsistency of preferences) underlie what are the genuine problems that anger creates for rational choice.

Dietary patterns and serum gamma-glutamyl transferase in Japanese men and women.

BACKGROUND Although specific foods and nutrients have been examined as potential determinants of serum gamma-glutamyl transferase (GGT) concentrations, the relationship between dietary patterns and GGT remains unknown. The present cross-sectional study aimed to determine relationships between dietary patterns and GGT concentrations, and the effects of lifestyle factors on GGT. METHODS Relationships between dietary patterns and GGT were analyzed in 9803 Japanese individuals (3723 men and 6080 women age 40-69 years) without a history of liver diseases or elevated serum aminotransferase. We examined major dietary patterns by factor analysis of 46 items determined from a validated, short food frequency questionnaire. RESULTS We defined dietary patterns as healthy, Western, seafood, bread, and dessert. The healthy pattern was inversely related to GGT in men (odds ratio [OR] for highest vs lowest quartile, 0.72; 95% confidence interval [CI], 0.57-0.92; P < 0.01 for trend) and women (OR 0.82; 95% CI, 0.66-1.0; P = 0.05 for trend), whereas the seafood pattern was positively related to GGT in men (OR 1.27; 95% CI, 1.01-1.61; P = 0.03 for trend) and women (OR 1.21; 95% CI, 0.98-1.49; P = 0.05 for trend). Male-specific inverse associations with GGT were found for bread and dessert patterns (OR 0.63; 95% CI, 0.50-0.80 and OR 0.53; 95% CI, 0.41-0.68, respectively; P < 0.01 for both trends). Seafood or bread patterns and alcohol consumption significantly interacted with GGT in men (P = 0.03 and <0.01 for interaction, respectively) and between the dessert pattern and body mass index or smoking habit in women (P = 0.03 and <0.01, respectively, for interaction). CONCLUSIONS Dietary patterns may be important determinants of GGT, and their possible clinical implications warrant further investigation.
The Effect of Allogenic Freeze Dried Platelet-Rich Plasma in Immunological Responses of Rabbits

This study aims to analyze the effects of allogenic freeze-dried platelet-rich plasma (PRP) in immunological responses of rabbits. This study employed a design of conducting one pre-post test group to determine the effect of freeze drying on levels of TGF-β1 PRP and the post test design was only for control group conducted to determine the effect of allogenic freeze-dried PRP. Levels of TGF-β1 before and after freeze drying from nine samples of PRP were examined which were obtained from blood centrifugation of three rabbits. These nine samples were used as allogenic donor injected intramuscularly in nine rabbits for the treatment groups. The control group used nine rabbits injected intramuscularly using autologous PRP. Inflammatory response and increasing levels of IgM were observed from both groups resulted in data which were then tested statistically using independent T-test. Measurement of TGF-β1 levels before and after freeze drying were tested statistically using Ttest dependent. The results showed that freeze drying process did not affect levels of TGF-β1. Allogenic freeze-dried PRP did not cause an inflammatory response in addition to not increasing levels of IgM.
Empowering Children And Teachers In The Elementary Mathematics Classrooms Of Urban Schools

Project IMPACT is a school-based teacher enhancement model for elementary mathematics instruction designed to foster student understanding and to support teacher change in predominantly minority elementary schools. Project teachers consider instructional approaches consistent with a cognitive, constructivist perspective for mathematics learning, emphasizing interaction and collaboration rather than limiting instruction to a direct model. Data from the primary grades revealed that significantly higher mathematics achievement scores for the children in the IMPACT schools emerged gradually and persistently over time, becoming more evident as the mathematical abstraction of the curriculum increased. Supported by mathematics specialists, instructional change occurred in most treatment classrooms, particularly in those schools where the principal encouraged the reform.
Learning Temporal Dependencies in Data Using a DBN-BLSTM

Since the advent of deep learning, it has been used to solve various problems using many different architectures. The application of such deep architectures to auditory data is also not uncommon. However, these architectures do not always adequately consider the temporal dependencies in data. We thus propose a new generic architecture called the Deep Belief Network - Bidirectional Long Short-Term Memory (DBN-BLSTM) network that models sequences by keeping track of the temporal information while enabling deep representations in the data. We demonstrate this new architecture by applying it to the task of music generation and obtain state-of-the-art results.
