Analyzing crowdsourced promotion effects in online social networks

In recent years, crowdsourcing has been actively used for many people to promote their products in online social networks (OSN), e.g., Twitter. The promotion activity in Twitter is typically performed by retweeting tweets by some accounts, called workers who earn monetary profits by deliberately promoting products for a requester. In this process, a fundamental question is whether the promotions by workers are really effective or not. To answer this question, in this paper, we analyze topological characteristics for the networks of workers, and evaluate the effect of promotions. Our empirical study demonstrates that the network of workers tends to be connected as a small-world network and their promotions show low impacts in the network of workers.
Partition-Based Parallel PageRank Algorithm

A re-ranking technique, called "PageRank", brings a successful story behind the Googletrade search engine. Many studies focus on finding an efficient way to compute the PageRank scores of a large web graph. Researchers propose to compute them sequentially by reducing the I/O cost of disk access, improving the convergence rate, or even employing peer-2-peer architecture, etc. However, only a few concentrate on computation using parallel processing techniques. In this paper, we propose a partition-based parallel PageRank algorithm that can efficiently be run on a low-cost parallel environment like PC cluster. For comparison, we also study other two well-known PageRank techniques, and provide an analytical discussion of their performance in terms of I/O and synchronization cost, as well as memory usage. Experimental results show a promising improvement on a large artificial web graph synthesized from the TH domain
Aggression, Self-Understanding, and Social Competence in Swiss Elementary-School Children

This study examined the relation between aggression, self-understanding, and social competence in a sample of 93 Swiss elementary-school children. Aggression was rated by the parents using the aggression subscale of the Child Behavior Checklist (CBCL/4-18). Self-understanding was assessed with a short version of Damon and Hart’s (1988) self-understanding interview. The social competence of the children was observed in a quasi-experimental, cooperative play situation. The results revealed that aggression was related to domain-specific content aspects of self-understanding. Aggression was, however, negatively associated with social competence. Moreover, nonaggressive children with high levels of self-understanding showed more social competence than aggressive children with both high and low levels of self-understanding.
Eukaryotic transcription factor binding sites - modeling and integrative search methods

A comprehensive knowledge of transcription factor binding sites (TFBS) is important for a mechanistic understanding of transcriptional regulation as well as for inferring gene regulatory networks. Because the DNA motif recognized by a transcription factor is typically short and degenerate, computational approaches for identifying binding sites based only on the sequence motif inevitably suffer from high error rates. Current state-of-the-art techniques for improving computational identification of binding sites can be broadly categorized into two classes: (1) approaches that aim to improve binding motif models by extracting maximal sequence information from experimentally determined binding sites and (2) approaches that supplement binding motif models with additional genomic or other attributes (such as evolutionary conservation). In this review we will discuss recent attempts to improve computational identification of TFBS through these two types of approaches and conclude with thoughts on future development.
Resilient Distribution System by Microgrids Formation After Natural Disasters

Microgrids with distributed generation (DG) provide a resilient solution in the case of major faults in a distribution system due to natural disasters. This paper proposes a novel distribution system operational approach by forming multiple microgrids energized by DG from the radial distribution system in real-time operations to restore critical loads from the power outage. Specifically, a mixed-integer linear program is formulated to maximize the critical loads to be picked up while satisfying the self-adequacy and operation constraints for the microgrids formation problem by controlling the ON/OFF status of the remotely controlled switch devices and DG. A distributed multiagent coordination scheme is designed via local communications for the global information discovery as inputs of the optimization, which is suitable for autonomous communication requirements after the disastrous event. The formed microgrids can be further utilized for power quality control and can be connected to a larger microgrid before the restoration of the main grids is complete. Numerical results based on modified IEEE distribution test systems validate the effectiveness of our proposed scheme.
Latino/a Voices in Australia: Negotiating Bilingual Identity

In Australia, bilingual identity and home language retention/attrition in bilingual children has had little research attention. This is particularly true in the early years of life where identity construction emerges in the context of early childhood education. This article begins with an overview of the Australian context to focus attention on the limited provision of bilingual support in early childhood settings. By drawing on the work in identity and hybridity negotiation, the ‘voices' of six Latin American parents are discussed to show how identities are negotiated and intersect with language retention within the social fields of ‘race’, ethnicity and gender differences. Three emerging themes are highlighted: the diversity of the parents' experiences in negotiating identity and language retention in family life; the parents' experiences of identity as multiple; and identity as a site of transformation and struggle in child rearing and gendered family practices. These findings demonstrate the significance of parents' perspectives and experiences of identity and language retention in raising their children bilingually, which can inform equitable and innovative practices in the provision of bilingual support in early childhood settings. In conclusion, the author invites early childhood educators to reframe their understandings of identity construction in young bilingual children.
The Extraordinary “Superthin” Spiral Galaxy UGC 7321. II. The Vertical Disk Structure

We explore the vertical light distribution as a function of galactocentric radius in the edge-on (i = 88°) Sd "superthin" galaxy UGC 7321. UGC 7321 is a low-luminosity spiral (MB,i = -17.0) with a diffuse, low surface brightness stellar disk and no discernible bulge component. Within ∼ 0. ′25 (∼725 pc) of the disk center the global luminosity profile of UGC 7321 can be reasonably characterized by an exponential function with a scale height hz ∼ 2. ″9 (∼140 pc) in H and hz ∼ 3. ″1 (∼150 pc) in R, making this among the thinnest galaxy disks known. Near the disk center we derive a ratio of disk scale length to global disk scale height hr/hz ∼ 14 in both H and R; near the edge of the disk, hr/hz ∼ 10. At intermediate galactocentric radii (0.′25 ≤ |r| ≤ 1.′5), the disk of UGC 7321 becomes less peaked than an exponential near the galactic plane. At these radii the vertical luminosity profiles can be well reproduced by a linear combination of two isothermal disk components of differing scale heights. These fits, together with the strong disk color gradients by Matthews, Gallagher, & van Driel, suggest that UGC 7321 has multiple disk subcomponents comprised of stellar populations with different ages and velocity dispersions. Thus even examples of the thinnest pure disk galaxies exhibit complex structure and signatures of dynamical heating.

This timer apparatus includes a timer for counting a clock pulse, a circuit for setting different times having a constant period from different termials and an output circuit for outputting a signal to the terminal at which the time was set from the corresponding terminal when the time coincides with a time signal output from the timer.
MeasureMent of cognitive distortions in child Molesters

The aim of this paper is to summarize and evaluate previous attempts at the measurement of cognitive distortions in child mo lesters. The concept of cognitive distortions has been conceptualized using Ward and keenan’s (1999) theory as the manifesta tion of causal implicit theories concerning the perpetrator, the victim, the surroundings, and the relationships between these elements. After reviewing the research, three generations of studies have been distinguished. The first generation studies were conducted using questionnaires. Their results have provided evidence that child molesters manifest cognitive distortions, but due to insufficient conceptualization, the possibilities of their interpretation were strongly limited. in the second generation studies, a clear conceptualization of the concept of cognitive distortions was delineated and a variety of tools was used, but these did not provide conclusive results. in the third generation studies a simultaneous use of several various methods of measurement of cognitive distortions was postulated. All the previous studies had only partially confirmed the theoretical assumptions. it is necessary to conduct further research, taking into account several groups of participants, with simultaneous measurement of cognitive distortions using several various tools based on the same theoretical conceptualization.
Exploring psychological difference between adopters and non-adopters of user generated audience segmenting functions

This exploratory study attempts to seek differences in levels of narcissism, Machiavellianism, self-monitoring, Internet self-efficacy (ISE), and privacy concerns and controls between adopters and non-adopters of audience segmenting on SNS, e.g. Friend List on Facebook. The uses and gratification framework was applied to build hypotheses. A survey ( N =100) was conducted to test the hypotheses. Although the difference is not significant at a level that would demonstrate support for the proposed hypotheses, adopters in the sample did exhibit higher levels of narcissism, self-monitoring, ISE, and privacy concerns and control. To yield more convincing results, recommendations are provided for future improvement. suggest that whether adopting Friend List or not does have an effect on ISE.
Using mice to model Alzheimer's dementia: an overview of the clinical disease and the preclinical behavioral changes in 10 mouse models

The goal of this review is to discuss how behavioral tests in mice relate to the pathological and neuropsychological features seen in human Alzheimer's disease (AD), and present a comprehensive analysis of the temporal progression of behavioral impairments in commonly used AD mouse models that contain mutations in amyloid precursor protein (APP). We begin with a brief overview of the neuropathological changes seen in the AD brain and an outline of some of the clinical neuropsychological assessments used to measure cognitive deficits associated with the disease. This is followed by a critical assessment of behavioral tasks that are used in AD mice to model the cognitive changes seen in the human disease. Behavioral tests discussed include spatial memory tests [Morris water maze (MWM), radial arm water maze (RAWM), Barnes maze], associative learning tasks (passive avoidance, fear conditioning), alternation tasks (Y-Maze/T-Maze), recognition memory tasks (Novel Object Recognition), attentional tasks (3 and 5 choice serial reaction time), set-shifting tasks, and reversal learning tasks. We discuss the strengths and weaknesses of each of these behavioral tasks, and how they may correlate with clinical assessments in humans. Finally, the temporal progression of both cognitive and non-cognitive deficits in 10 AD mouse models (PDAPP, TG2576, APP23, TgCRND8, J20, APP/PS1, TG2576 + PS1 (M146L), APP/PS1 KI, 5×FAD, and 3×Tg-AD) are discussed in detail. Mouse models of AD and the behavioral tasks used in conjunction with those models are immensely important in contributing to our knowledge of disease progression and are a useful tool to study AD pathophysiology and the resulting cognitive deficits. However, investigators need to be aware of the potential weaknesses of the available preclinical models in terms of their ability to model cognitive changes observed in human AD. It is our hope that this review will assist investigators in selecting an appropriate mouse model, and accompanying behavioral paradigms to investigate different aspects of AD pathology and disease progression.
The Levenberg-Marquardt-Type Methods for a Kind of Vertical Complementarity Problem

Two kinds of the Levenberg-Marquardt-type methods for the solution of vertical complementarity problem are introduced. The methods are based on a nonsmooth equation reformulation of the vertical complementarity problem for its solution. Local and global convergence results and some remarks about the two kinds of the Levenberg-Marquardt-type methods are also given. Finally, numerical experiments are reported.
DMP: deterministic shared memory multiprocessing

Current shared memory multicore and multiprocessor systems are nondeterministic. Each time these systems execute a multithreaded application, even if supplied with the same input, they can produce a different output. This frustrates debugging and limits the ability to properly test multithreaded code, becoming a major stumbling block to the much-needed widespread adoption of parallel programming. In this paper we make the case for fully deterministic shared memory multiprocessing (DMP). The behavior of an arbitrary multithreaded program on a DMP system is only a function of its inputs. The core idea is to make inter-thread communication fully deterministic. Previous approaches to coping with nondeterminism in multithreaded programs have focused on replay, a technique useful only for debugging. In contrast, while DMP systems are directly useful for debugging by offering repeatability by default, we argue that parallel programs should execute deterministically in the field as well. This has the potential to make testing more assuring and increase the reliability of deployed multithreaded software. We propose a range of approaches to enforcing determinism and discuss their implementation trade-offs. We show that determinism can be provided with little performance cost using our architecture proposals on future hardware, and that software-only approaches can be utilized on existing systems.
Phosphorylation of PNKP by ATM prevents its proteasomal degradation and enhances resistance to oxidative stress

We examined the mechanism regulating the cellular levels of PNKP, the major kinase/phosphatase involved in the repair of oxidative DNA damage, and find that it is controlled by ATM phosphorylation and ubiquitylation-dependent proteasomal degradation. We discovered that ATM-dependent phosphorylation of PNKP at serines 114 and 126 in response to oxidative DNA damage inhibits ubiquitylation-dependent proteasomal degradation of PNKP, and consequently increases PNKP stability that is required for DNA repair. We have also purified a novel Cul4A-DDB1 ubiquitin ligase complex responsible for PNKP ubiquitylation and identify serine–threonine kinase receptor associated protein (STRAP) as the adaptor protein that provides specificity of the complex to PNKP. Strap−/− mouse embryonic fibroblasts subsequently contain elevated cellular levels of PNKP, and show elevated resistance to oxidative DNA damage. These data demonstrate an important role for ATM and the Cul4A-DDB1-STRAP ubiquitin ligase in the regulation of the cellular levels of PNKP, and consequently in the repair of oxidative DNA damage.
Joint Grammar Development by Linguists and Computer Scientists

For languages with inflectional morphology, development of a morphological parser can be a bottleneck to further development. We focus on two difficulties: first, finding people with expertise in both computer programming and the linguistics of a particular language, and second, the short lifetime of software such as parsers. We describe a methodology to split parser building into two tasks: descriptive grammar development, and formal grammar development. The two grammars are combined into a single document using Literate Programming. The formal grammar is designed to be independent of a particular parsing engine’s programming language, so that it can be readily ported to a new parsing engine, thus helping solve the software lifetime problem.
Aptamer Internalization via Endocytosis Inducing S-Phase Arrest and Priming Maver-1 Lymphoma Cells for Cytarabine Chemotherapy

The goal of precision therapy is to efficiently treat cancer without side effects. Aptamers are a class of small ligands composed of single-stranded oligonucleotides that bind to their targets with high affinity and specificity. In this study, we identified an ssDNA aptamer specifically targeting Maver-1 lymphoma cells with high binding affinity (Kd = 70±8 pmol/L). Interestingly, cellular cycle studies revealed that exposure of Maver-1 cells to synthetic aptamers triggered S-phase arrest of 40% of the cells (vs. 18% baseline). Confocal microscopy confirmed specific cell binding of aptamers and the resultant endocytosis into Maver-1 cells. Subsequent functional assays validated the fact that aptamer internalization into targeted cells is a prerequisite for Maver-1 cell growth inhibition. Importantly, aptamer-induced S-phase arrest induced enhanced chemotherapeutic results involving cytarabine, which primarily kills lymphoma cells at S-phase. Combination treatments revealed that aptamer re-exposure considerably primed Maver-1 cells for cytarabine chemotherapy, thus achieving a synergistic killing effect by reaching cell death rates as high as 61% (vs. 13% or 14% induced by aptamer or cytarabine treatment alone). These findings demonstrated that aptamers do not only act as molecular ligands but can also function as biotherapeutic agents by inducing S-phase arrest of lymphoma cells. In addition, logical combination of aptamer and cytarabine treatments ushers the way to a unique approach in precision lymphoma chemotherapy.
Working Overtime is Associated With Anxiety and Depression: The Hordaland Health Study

Objective:To examine whether long work hours are associated with increased levels and prevalences of anxiety and depression. Methods:Overtime workers (n = 1350) were compared with a reference group of 9092 workers not working overtime regarding anxiety and depression by means of the Hospital Anxiety and Depression Scale. Self-reported information on various work-related factors, demographics, lifestyle, and somatic health was included. Results:Overtime workers of both genders had significantly higher anxiety and depression levels and higher prevalences of anxiety and depressive disorders compared with those working normal hours. Findings suggest a dose-response relationship between work hours and anxiety or depression. Conclusions:Working overtime is associated with increased levels of anxiety and depression. The working groups differed significantly regarding several factors including income and heavy manual labor.
Censorship resistant overlay publishing

The fundamental requirement of censorship resistance is content availability and discoverability — it should be easy for users to find and access documents. At the same time, participating storage providers should be unaware of what they are storing to preserve plausible deniability. Fulfilling these requirements simultaneously seems impossible — how does a system maintain a searchable index of content for users and yet hide it from storage providers? These paradoxical requirements have been previously reconciled by requiring out-of-band communication to either find ways to connect to the system, locate files, or learn file decryption keys — an unacceptable situation when easy content discovery is critical. This paper describes a design for a peer-to-peer, permanent, and unblockable content store which is easily searchable and yet self-contained, i.e. does not require out-of-band communication. To achieve this, we separate file data, metadata, and encryption keys such that someone searching for information about a specific topic can retrieve all three components and reconstruct the file, but someone who only stores at most two components can neither determine the nature of the file content nor locate the missing component. We begin by identifying the core requirements for unblockable storage systems to resist state-level Internet censorship, construct a system that fulfills those requirements, and analyze how it avoids the problem of prior attempts at censorship resistance. Finally, we present measurements of a deployed proof-of-concept implementation, demonstrating the feasibility of our design.
Hazardous Drinking-Related Characteristics of Depressive Disorders in Korea: The CRESCEND Study

This study aimed to identify clinical correlates of hazardous drinking in a large cohort of Korean patients with depression. We recruited a total of 402 depressed patients aged > 18 yr from the Clinical Research Center for Depression (CRESCEND) study in Korea. Patients' drinking habits were assessed using the Korean Alcohol Use Disorder Identification Test (AUDIT-K). Psychometric scales, including the HAMD, HAMA, BPRS, CGI-S, SSI-Beck, SOFAS, and WHOQOL-BREF, were used to assess depression, anxiety, overall psychiatric symptoms, global severity, suicidal ideation, social functioning, and quality of life, respectively. We compared demographic and clinical features and psychometric scores between patients with and without hazardous drinking behavior after adjusting for the effects of age and sex. We then performed binary logistic regression analysis to identify independent correlates of hazardous drinking in the study population. Our results revealed that hazardous drinking was associated with current smoking status, history of attempted suicide, greater psychomotor retardation, suicidal ideation, weight loss, and lower hypochondriasis than non-hazardous drinking. The regression model also demonstrated that more frequent smoking, higher levels of suicidal ideation, and lower levels of hypochondriasis were independently correlates for hazardous drinking in depressed patients. In conclusion, depressed patients who are hazardous drinkers experience severer symptoms and a greater burden of illness than non-hazardous drinkers. In Korea, screening depressed patients for signs of hazardous drinking could help identify subjects who may benefit from comprehensive therapeutic approaches. Graphical Abstract
