Multiple Similarities for Diversity in Recommender Systems

Compared to search engines, recommender systems provide another means to help users to access information. Recommender systems are designed to automatically provide useful items to users. A new challenge for recommender systems is to provide diversified recommendations. In this paper, we investigate an approach to obtain more diversified recommendations using an aggregation method based on various similarity measures. This work is evaluated using three experiments: the two first ones are lab experiments and show that aggregation of various similarity measures improves accuracy and diversity. The last experiment involved real users to evaluate the aggregation method we propose. We show that this method allows the balance between accuracy and diversity of recommendations.

Formulaic Language in Language Socialization

This article reviews recent research on the roles of formulaic language in language socialization theory and research from the point of view that formulaic language is a chunk of language (e.g., one word, string of several words) repeatedly used in verbal routines and other contexts. Although the notion of formulaic language is not always explicitly discussed in the literature of language socialization, previous research suggests that formulaic language is indeed an important notion within the theory of language socialization, for it often plays a crucial role in socializing novices to social dimensions such as politeness, hierarchy, and social identities including social roles and statuses, and relationships. This article first provides a brief introduction of language socialization theory, its research methods, and recent developments. It then reviews recent language socialization research on formulaic language in first and second language (L1, L2) and heritage language environments, including how novices are socialized to use formulaic language, how they are socialized through its use, and how they actually use it in normative and novel ways in participating in social interaction with experts and/or peers. Finally, the major findings of recent studies are summarized, and the article concludes by suggesting several directions for further research on formulaic language in language socialization.
A personality-based model of agents for representing individuals in working organizations

This paper proposes an agent architecture which can be used to represent individuals within a working organization. The proposed architecture has been based on the theory of human personality and its working relationship from Theodore Milton. The main aim of this paper is to describe a suitable representation of individual behaviors which is able to be mapped to collective patterns of a human organization. The proposed architecture has been used in the SimOrg project, which aims to apply a multi-agent simulation in human organizations.

Sentiment Analysis in Chinese Web Discussion Forums

Online discussions serve as a bridge between face-to-face and virtual lessons in the distance education. Previous researches have investigated the impact of student participation in online discussions on learning performance. However, student opinions expressed in the posts are also good indicators to student learning. The recent achievements of the natural language processing technologies, especially sentiment analysis in Chinese makes it possible to automatically detect the polarity of each course post. In this study, we collected online posts from 62 students in a distance education course program and used machine learning algorithms to build a sentiment classifier. The features were extracted from a recent developed Chinese affective lexical resource. Finally, we examined the impact of the post opinion on the student final grade. As a result, it is found that the decision tree classifier got the highest Marco-average F1-score (0.693) and the correlation between the student post sentiments and final grade is moderate.
PENGARUH TERAPI PEMAAFAN UNTUK MENINGKATKAN PENERIMAAN DIRI PADA PENDERITA KANKER PAYUDARA

Biological, psychological, social, and spiritual impacts of cancer can cause the emergence of negative emotions and affect patient's self-acceptance. Forgiveness therapy is expected to enhance patient's acceptance by releasing them from the negative emotional prison, changing attitudes toward self, others, and/ or the situation become more positive, and setting new life goals. This study examined the effect of forgiveness therapy to increase forgiveness and self-acceptance of breast cancer patients. Therapy was given as much as 6 sessions, conducted once a week, for about 80 minutes. Participant was a woman who had a breast cancer, had a average score of forgiveness self-acceptance on the baseline phase measurement. Reseach design was A-B-A single-case experimental studies with 3 times forgiveness's meansurement, each before intervention, after intervention, and follow-up 2 weeks after intervention. Self-acceptance's measurement was conducted 10 times, 3 times in the baseline phase (before intervention), 6 times in the intervention phase (end of each session), 1 time in reversal phase (follow-up 2 weeks after intervention), with 1 week meansurement interval. Hypothesis was tested by using visual inspection and qualitative analysis based on documents during the process of therapy and follow-up interview. The results showed that forgiveness therapy could improve participant's forgiveness and self-acceptance. Changes in both dependent variable remained stable at follow-up. The limitations of this study were further discussed.
Purification and characterization of an aminopeptidase from Lactobacillus casei subsp. rhamnosus S93

An aminopeptidase of broad specificity was extracted by cell lysis of a selected strain of Lactobacillus casei subsp. rhamnosus during the late exponential phase. The enzyme was purified 195‐fold from crude extract by using an f.p.l.c. system. Native and SDS/PAGE of the purified enzyme showed a single protein band of 89 kDa. The maximum aminopeptidase activity was observed at pH 7.0 and 39 degrees C. The enzyme hydrolysed a range of nitroanilide‐substituted amino acids, as well as dipeptides, and accounted for most of the aminopeptidase activity found in cell‐free extracts. The enzyme activity was inhibited by metal chelators such as EDTA and 1,10‐phenanthroline. Cobalt ions only stimulated aminopeptidase activity and were also able to re‐activate the enzyme previously inhibited by metal chelators. The Km and Vmax. values of the aminopeptidase for leucine p‐nitroanilide were 0.06 mM and 12.6 mmol/min per mg of protein respectively. This enzyme was stable over the pH range of 5‐9 and below 45 degrees C.
Factors influencing the agile methods in practice - Literature survey & review

The software industry in India has been growing at phenomenal rates over the last twenty years. Currently stands at $ 70 Billion in revenue and targeted towards $300 Billion size in next four years. It has been showing constant growth of over 20 % consistently irrespective of global slowdown and - anti offshore policy by some countries in near future. Even after this tremendous rate of growth, the process that is used to develop the software product has not changed completely and research on factors affecting the use of method to develop the product is not given importance in Indian scenario.

Dendritic Cells Engineered to Express Defined Allo‐HLA Peptide Complexes Induce Antigen‐specific Cytotoxic T Cells Efficiently Killing Tumour Cells

Most tumour‐associated antigens (TAA) are non‐mutated self‐antigens. The peripheral T cell repertoire is devoid of high‐avidity TAA‐specific cytotoxic T lymphocytes (CTL) due to self‐tolerance. As tolerance is major histocompatibility complex‐restricted, T cells may be immunized against TAA presented by a non‐self human leucocyte antigen (HLA) molecule and transferred to cancer patients expressing that HLA molecule. Obtaining allo‐restricted CTL of high‐avidity and low cross‐reactivity has, however, proven difficult. Here, we show that dendritic cells transfected with mRNA encoding HLA‐A*0201, efficiently present externally loaded peptides from the antigen, Melan‐A/MART‐1 to T cells from HLA‐A*0201‐negative donors. CD8+ T cells binding HLA‐A*0201/MART‐1 pentamers were detected already after 12 days of co‐culture in 11/11 donors. The majority of cells from pentamer+ cell lines were CTL and efficiently killed HLA‐A*0201+ melanoma cells, whilst sparing HLA‐A*0201+ B‐cells. Allo‐restricted CTL specific for peptides from the leukaemia‐associated antigens CD33 and CD19 were obtained with comparable efficiency. Collectively, the results show that dendritic cells engineered to express defined allo‐HLA peptide complexes are highly efficient in generating CTL specifically reacting with tumour‐associated antigens.
X-RAY AND OPTICAL STUDY OF LOW CORE DENSITY GLOBULAR CLUSTERS NGC6144 AND E3

We report on the Chandra X-ray Observatory and Hubble Space Telescope (HST) observations of two low core-density globular clusters, NGC6144 and E3. By comparing the number of X-ray sources inside the half-mass radius to those outside, we found six X-ray sources within the half-mass radius of NGC6144, of which four are expected to be background sources; three X-ray sources are also found within the half-mass radius of E3, of which three are expected to be background sources. Therefore, we cannot exclude the possibility that all our sources are background sources. However, combining the results from X-ray and optical observations, we found that one to two sources in NGC6144 and one source in E3 are likely to be cataclysmic variables and that one source in NGC6144 is an active binary, based on the X-ray and optical properties. The number of faint X-ray sources in NGC6144 and E3 found with Chandra and HST is higher than a prediction based on collision frequency, but is closer to that based on mass. Our observations strongly suggest that the compact binary systems in NGC6144 and E3 are primordial in origin.
The Impact of Social Curiosity on Information Spreading on Networks

Most information spreading models consider that all individuals are identical psychologically. They ignore, for instance, the curiosity level of people, which may indicate that they can be influenced to seek for information given their interest. For example, the game Pokémon GO spread rapidly because of the aroused curiosity among users. This paper proposes an information propagation model considering the curiosity level of each individual, which is a dynamical parameter that evolves over time. We evaluate the efficiency of our model in contrast to traditional information propagation models, like SIR or IC, and perform analysis on different types of artificial and real-world networks, like Google+, Facebook, and the United States roads map. We present a mean-field approach that reproduces with a good accuracy the evolution of macroscopic quantities, such as the density of stiflers, for the system’s behavior with the curiosity. We also obtain an analytical solution of the mean-field equations that allows to predicts a transition from a phase where the information remains confined to a small number of users to a phase where it spreads over a large fraction of the population. The results indicate that the curiosity increases the information spreading in all networks as compared with the spreading without curiosity, and that this increase is larger in spatial networks than in social networks. When the curiosity is taken into account, the maximum number of informed individuals is reached close to the transition point. Since curious people are more open to a new product, concepts, and ideas, this is an important factor to be considered in propagation modeling. Our results contribute to the understanding of the interplay between diffusion process and dynamical heterogeneous transmission in social networks.
Metabolic Syndrome in Children and Adolescents

Metabolic syndrome (MetS) is a cluster of metabolic abnormalities that include hypertension, altered glucose metabolism, dyslipidemia, and abdominal obesity and is strongly associated with an increased risk for diabetes and cardiovascular disease onset in obese adults and children. A progressively greater number of children and adolescents are being affected by this syndrome due to the constant increase in the prevalence of obesity. Like obesity, childhood MetS highly tracks to adulthood. The pathogenesis of MetS includes the interaction between obesity, insulin resistance, and inflammation. Early diagnosis and intervention are important in order to conduct lifestyle modification. In this article, we review the definition and pathophysiology of MetS, the importance of screening, and prevention and treatment options for MetS in childhood.
μ- and δ-Opioid-Related Processes in the Accumbens Core and Shell Differentially Mediate the Influence of Reward-Guided and Stimulus-Guided Decisions on Choice

Two motivational processes affect choice between actions: (1) changes in the reward value of the goal or outcome of an action and (2) changes in the predicted value of an action based on outcome-related stimuli. Here, we evaluated the role of μ-opioid receptor (MOR) and δ-opioid receptor (DOR) in the nucleus accumbens in the way these motivational processes influence choice using outcome revaluation and pavlovian-instrumental transfer tests. We first examined the effect of genetic deletion of MOR and DOR in specific knock-out mice. We then assessed the effect of infusing the MOR antagonist d-Phe-Cys-Tyr-d-Trp-Arg-Thr-Pen-Thr-NH2 (CTAP) or the DOR antagonist naltrindole into the core or shell subregions of the nucleus accumbens on these tests in rats. We found that, whereas MOR knock-outs showed normal transfer, they failed to show a selective outcome revaluation effect. Conversely, DOR knock-outs showed normal revaluation but were insensitive to the influence of outcome-related cues on choice. This double dissociation was also found regionally within the nucleus accumbens in rats. Infusion of naltrindole into the accumbens shell abolished transfer but had no effect on outcome revaluation and did not influence either effect when infused into the accumbens core. Conversely, infusion of CTAP into the accumbens core abolished sensitivity to outcome revaluation but had no effect on transfer and did not influence either effect when infused into the accumbens shell. These results suggest that reward-based and stimulus-based values exert distinct motivational influences on choice that can be doubly dissociated both neuroanatomically and neurochemically at the level of the nucleus accumbens.
Welcome to the end of the world! Resignifying periphery under the new economy: a nexus analytical view of a tourist website

Accompanying the rise of the globalized new economy, the heritage tourism industry is expanding ever further into the global peripheries. One such ‘peripheral’ site is Sámiland, home of the indigenous language minority Sámi people, in the north of Lapland. Here, tourism is emerging as an opportunity for the Sámi to challenge their longstanding marginalization by mobilizing the periphery and signifying their peripheralized identities in new ways. These processes may look encouraging but they call for critical interrogation. To gain a deeper insight into these processes, the present study draws on a nexus analytical approach combining discourse analysis and ethnography to examine an illuminating case: discursive construction of ‘the periphery’ on a website advertising guesthouses in northern Lapland run by a Sámi woman who is an artist and entrepreneur. The investigation shows how, drawing on a variety of local, global and personal sources of signification, ‘the periphery’ is constructed as a hybrid and polycentric space, a construction that challenges persisting conceptions of peripheral regions as homogeneous and immutable. An examination of the material factors underlying this discursive construction leads to the question of how these emerging possibilities are actually linked to socioeconomic conditions and suggests implications for future research.
Deterministic Quality of Service Guarantee for Dynamic Service Chaining in Software Defined Networking

In this paper, we present a systemic approach to provide deterministic delay guarantee for dynamic service chaining in software defined networking (SDN). The delay performance of service chaining in SDN is affected by signaling message exchange in control plane and packet transmissions in data plane, respectively. First, we develop an analytical method to characterize the delay performance of control plane when handling traffic with different priorities according to network calculus (NC) and queuing theory. Second, taking into account the estimated delay in control plane, we propose a novel service traversal mechanism to calculate the optimal traversal path for the service chain. We demonstrate that NC delay analysis can provide deterministic quality of service (QoS)-guaranteed service chaining for any specified delay requirements, whereas theoretical queueing delay analysis can only provide statistical QoS guarantee. In summary, the proposed NC delay analysis can help to understand the network design for a future delay sensitive Internet in which deterministic latency must be guaranteed.
When Your Race Is Almost Run, but You Feel You're Not yet Done: Application of the Propulsion Theory of Creative Contributions to Late-Career Challenges.

The propulsion theory of creative contributions is a theory that focuses on how a creative act or product builds on and adds to knowledge in various fields. In this article, we apply the propulsion theory of creative contributions not to creative discoveries or inventions, but rather to late-career decisions about future directions in which one can steer one's career. We consider eight different kinds of career decisions one can make—replication, redefinition, forward incrementation, advance forward incrementation, redirection, reconstruction/redirection, reinitiation, and synthesis. Each offers a viable option for closing out a creative career.
Low PAPR square STBCs from complex partial-orthogonal designs (CPODs)

Space-time codes from complex orthogonal designs (CODs) with no zero entries offer low Peak to Average Power Ratio (PAPR) and avoid the problem of switching off antennas. But square CODs for 2a antennas with a+1 complex variables, with no zero entries were discovered only for a les 3 and if a+1 = 2k, for k ges 4. In this paper, a method of obtaining no zero entry (NZE) square designs, called Complex Partial-Orthogonal Designs (CPODs), for 2a+1 antennas whenever a certain type of NZE code exists for 2a antennas is presented. Then, starting from a so constructed NZE CPOD for n = 2a+1 antennas, a construction procedure is given to obtain NZE CPODs for 2n antennas, successively. Compared to the CODs, CPODs have slightly more ML decoding complexity for rectangular QAM constellations and the same ML decoding complexity for other complex constellations. Using the recently constructed NZE CODs for 8 antennas our method leads to NZE CPODs for 16 antennas. The class of CPODs do not offer full-diversity for all complex constellations. For the NZE CPODs presented in the paper, conditions on the signal sets which will guarantee full diversity are identified. Simulation results show that bit error performance of our codes is same as that of the CODs under average power constraint and superior to CODs under peak power constraint.
Assessment of female and male fertility in Sprague-Dawley rats administered vorinostat, a histone deacetylase inhibitor.

BACKGROUND Histone deacetylase (HDAC) inhibitors have been shown to mediate the regulation of gene expression, induce cell growth, cell differentiation, and apoptosis of tumor cells. These compounds are now marketed or are in clinical development. One such HDAC inhibitor, vorinostat (suberoylanilide hydroxamic acid [SAHA], Zolinza), was assessed for its potential effects on fertility in Sprague-Dawley rats. METHODS Female rats were administered oral dose levels of 0 (vehicle only), 15, 50, or 150 mg/kg/day of vorinostat for 14 days before cohabitation, during cohabitation, and through Gestation Day (GD) 7. In a separate study, male rats were administered oral dose levels of 0 (vehicle only), 20, 50, or 150 mg/kg/day for 10 weeks before cohabitation, during cohabitation, and until the day before scheduled sacrifice (approximately 14 weeks total). In both studies, % peri-implantation loss and % postimplantation loss were evaluated on GD 15-17. Testicular weight and histomorphology, cauda epididymal sperm count, and sperm motility were evaluated in the male rat study at termination. RESULTS There were treatment-related decreases in body weight gain at 150 mg/kg/day in both studies. There were no effects on mating or fertility indices in either study. In the female study there were increased numbers of corpora lutea in all drug-treated groups (only 1 or 2 affected dams in low and mid-dose groups), and a marked increase in percent postimplantation loss only in the high-dose group. No treatment-related effects were observed on litter or sperm parameters of the male study. CONCLUSIONS Vorinostat had no effects on mating or fertility in rats up to 150 mg/kg/day. There were no indications of reproductive toxicity in drug-treated male rats. Increases in corpora lutea or resorptions were observed in treated female rats.
