Sequences, Items And Latent Links: Recommendation With Consumed Item Packs

Recommenders personalize the web content by typically using collaborative filtering to relate users (or items) based on explicit feedback, e.g., ratings. The difficulty of collecting this feedback has recently motivated to consider implicit feedback (e.g., item consumption along with the corresponding time). In this paper, we introduce the notion of consumed item pack (CIP) which enables to link users (or items) based on their implicit analogous consumption behavior. Our proposal is generic, and we show that it captures three novel implicit recommenders: a user-based (CIP-U), an item-based (CIP-I), and a word embedding-based (DEEPCIP), as well as a state-of-the-art technique using implicit feedback (FISM). We show that our recommenders handle incremental updates incorporating freshly consumed items. We demonstrate that all three recommenders provide a recommendation quality that is competitive with state-of-the-art ones, including one incorporating both explicit and implicit feedback.
Evolution of Software Development Strategies

The development of discipline-specific cognitive and meta-cognitive skills is fundamental to the successful mastery of software development skills and processes. This development happens over time and is influenced by many factors, however its understanding by teachers is crucial in order to develop activities and materials to transform students from novice to expert software engineers. In this paper, we analyse the evolution of learning strategies of novice, first year students, to expert, final year students. We analyse reflections on software development processes from students in an introductory software development course, and compare them to those of final year students, in a distributed systems development course. Our study shows that computer science - specific strategies evolve as expected, with the majority of final year students including design before coding in their software development process, but that several areas still require scaffolding activities to assist in learning development.
MODELS AND DISCOURSE : A PRIMARY SCHOOL SCIENCE CLASS VISIT TO A MUSEUM

A critical incident is viewed as an event which is sufficiently coherent and apparently significant, as reflected in the discourse which takes place between individuals in a group, to permit inferences to be made about the formation, use, and development of mental models. This approach was used to analyze the discourse which took place during a visit by a class of 8–9-year-olds to a gallery concerned with food at the Science Museum, London. Data were collected by observation and interview before, during, and after the visit. Events that lead to the initiation, continuation, and closure of discourse were identified, broad classifications produced, and inferences made about their impact on pupils' mental models. The conditions which produced evidence of mental engagement with exhibits included: The linking of the visit to the curriculum currently being followed at school; the pupils' being able to follow their own itinerary in the museum; the pupils being able to work in small friendship groups; the accompanying of each group by an adult with some knowledge about the topic of the exhibits. It is suggested that a critical incident approach may be helpful more generally in analyzing the learning which takes place in groups. © 1997 John Wiley & Sons, Inc. Sci Ed81:749–762, 1997.
Learning Characteristics of Verbally Gifted Students

Children identified as &dquo;gifted&dquo; are seen to differ from their more typical age mates, with respect to real or pre, dicted achievement. There is some question concerning ’ whether or not they differ with respect to certain other variables, however (George, Cohn, & Stanley, 1979; Stanley, Keating, & Fox, 1974; Terman, 1925). Areas of inquiry include cognition, learning, physical development, and psychosocial functioning. Some authors have suggested that &dquo;gifted&dquo; individuals learn in a manner qualita-
Physical Activity Related to Depression and Predicted Mortality Risk: Results from the Americans’ Changing Lives Study

This study examined the association between three types of physical activities (PA) and depression, and the relationship between PA and later mortality. Previous studies rarely assessed these associations in one single study in randomly selected population samples. Few studies have assessed these relations by adjusting the covariate of friend-relative care. Participants consisted of 624 noninstitutionalized elders (mean age = 77.35) from the Americans’ Changing Lives Longitudinal Study. Depression was measured using the Center for Epidemiological Studies Depression Scale. Logistic regression estimated the risk of depression as a function of the three individual PA (gardening, walking, and sport). A separate set of analyses predicted the risk of mortality (six years later) as a function of PA. Each 1-standard-unit increase on the physical inactivity scale significantly predicted adjusted 29%, 30%, and 33% increased risk of depression for gardening, walking, and sport, respectively; and each unit also predicted 48% and 72% increased risk of mortality, for gardening and walking, respectively. Active exercise was not able to predict mortality (p = .42). The study concluded that elders with less PA had a higher chance of getting depression. Unlike gardening and walking, rigorous exercise did not significantly predict mortality. This indicated that extra care is needed for elders when they engage in intense exercise. The relationships of social support from friends and relatives with depression and mortality were also discussed.
Trace amines: Identification of a family of mammalian G protein-coupled receptors

Tyramine, β-phenylethylamine, tryptamine, and octopamine are biogenic amines present in trace levels in mammalian nervous systems. Although some “trace amines” have clearly defined roles as neurotransmitters in invertebrates, the extent to which they function as true neurotransmitters in vertebrates has remained speculative. Using a degenerate PCR approach, we have identified 15 G protein-coupled receptors (GPCR) from human and rodent tissues. Together with the orphan receptor PNR, these receptors form a subfamily of rhodopsin GPCRs distinct from, but related to the classical biogenic amine receptors. We have demonstrated that two of these receptors bind and/or are activated by trace amines. The cloning of mammalian GPCRs for trace amines supports a role for trace amines as neurotransmitters in vertebrates. Three of the four human receptors from this family are present in the amygdala, possibly linking trace amine receptors to affective disorders. The identification of this family of receptors should rekindle the investigation of the roles of trace amines in mammalian nervous systems and may potentially lead to the development of novel therapeutics for a variety of indications.
ENTREPRENEURS AND MANAGERS: SIMILAR YET DIFFERENT

In recent years much research attention has focused on managers and entrepreneurs, but very few studies have compared the two. In the current exploratory study, 20 Israeli entrepreneurs (that are the focus of great curiosity but little research) were compared to 47 managers and to a control group of 33 aspiring entrepreneurs. They were interviewed regarding traits of their father, mother, and self. Findings revealed a number of similarities (a similar commitment) as well as differences (entrepreneurs' greater love of challenge) between the managers and the entrepreneurs. Entrepreneurs also described themselves as having a greater sense of significance in their work. The question why managers and entrepreneurs are who they are is answered within a psychoanalytic‐existential framework that focuses on the managers' positive identification with their father and better relationship with both parents as compared to the entrepreneurs' negative identification with father and greater identification with work. Implications for treatment are suggested.
The Revised Program Evaluation Standards and their Correlation with the Evaluation use Literature

Abstract Various strategies for optimizing the use of program evaluation information are recommended, based on an examination of the use literature. The recently revised Program Evaluation Standards (Joint Committee, 1994) are then reviewed as regards sensitivity to these recommendations. It appears that the new standards generally incorporate what the literature suggests should be regarded as best practice.
Some Personal Reflections on Probation Training

This research draws upon the author's personal experiences and the comments of his former colleagues on their perception of undertaking the Diploma in Probation Studies (DipPS) in the Midlands Region. This relatively recently established qualification, undertaken in order to be eligible to work as a probation officer in England and Wales, has created substantial discourse due to its break with social work traditions. This research was undertaken over a two-year period and intends to provide 'consumer' comment on the training and examines the perceptions of trainee probation officers (TPOs) on the suitability of these training arrangements. The author argues that whilst the intention of the programme was not to create an unquestioning 'enforcement' driven mentality, a number of trainees adopted just that. The article suggests that this is due to the tension created by a perceived disparity between the needs of the organisation and the demands of the university amongst the trainee group. This is reinforced by the imbalance in delivery, between the vocational and academic components. The author's view is that the current arrangements are too vocational in practice, and this is likely to continue, given the move towards delivery of the academic component through 'distance learning'. It argues that the future pre-qualifying arrangements need to retain a belief in the value of academia and be delivered (at least in part) outside the employment setting.
Inflammatory Cytokine Expression Patterns in Rat Skin Exposed to JP-8 Jet Fuel

One of the main complaints of personnel exposed to JP-8 jet fuel is irritant dermatitis. The purpose of this investigation is to describe the JP-8 induced inflammatory cytokine response in skin over various periods of exposure. JP-8 jet fuel or acetone control (300 μL) was applied to the denuded skin of rats once a day for up to seven days. Skin samples from the exposed area were collected after one, three, five and seven days of exposure. RT-PCR was performed utilizing total skin RNA to examine the expression of various inflammatory cytokines. The mRNA’s for the chemokines CXCL1, 2, 3 and 10, as well as CCL3, 5, 11 and 20 were variably modulated during the course of exposure, favoring the expression of those that attract PMN. IL-1β and IL-6 mRNA’s were significantly induced by five days, while IL-10 was not significantly different from control at any time point. Paradoxically, skin IL-6 protein content was found to decrease continually throughout the time course as determined by ELISA. Data from the present study indicates that repeated JP-8 exposure induces numerous proinflammatory cytokines in skin that tend to favor neutrophil accumulation. The increased expression of these cytokines and chemokines may lead to increased inflammatory infiltrate and injury of the skin, resulting in JP-8 induced irritant dermatitis.
Coupling of vesicle tethering and Rab binding is required for in vivo functionality of the golgin GMAP-210

Vesicle tethering mediated by the golgin GMAP-210 is required to maintain the structure of the Golgi apparatus. Tethering by GMAP-210 is mediated solely by the ALPS motif, and binding to Rab2 and the length of GMAP-210, although not required for tethering per se, are also critical for its functional role at the Golgi apparatus.
Newspaper Reporting and Public Perceptions of Party Finance in Britain: Knows Little, Learns Something?

A sizeable literature in political science considers the level of information citizens need to make informed policy choices, however, fewer studies examine the quality of information that is available to the public. While debate here has often characterized citizens as “informed” or “uninformed,” this article considers that the public may be mis-informed. Following Ansolabehere et al. (2005), I examine one source of mis-information – sampling bias – in newspaper reporting of party finance, and the extent to which individuals' estimates of donations and expenditures follow what is reported in the press. The data for the project come from three sources: a content analysis of major newspapers, survey data generated by YouGov's online panel (N = 2,008), and donation/expenditure reports from the regulator, the Electoral Commission. Analysis of the data here show evidence of sampling bias with respect to press reports on the size and source of donations and the relative spending priorities of the three main parties. Moreover, although public knowledge of key aspects of party finance is low, press reports provide little opportunity for the public to learn about party finance.
Interplay of quantum magnetic and potential scattering around Zn and Ni impurity ions in superconducting cuprates

To describe the scattering of superconducting quasiparticles from non-magnetic (Zn) or magnetic (Ni) impurities in optimally doped high-T-c cuprates, we propose an effective Anderson model Hamiltonian of a localized electron hybridizing with d(x)(2)-y(2)-wave BCS type superconducting quasiparticles with an attractive scalar potential at the impurity site. Due to the strong local antiferromagnetic couplings between the original Cu ions and their nearest neighbors, the localized electron in the Ni-doped materials is assumed to be on the impurity sites, while in the Zn-doped materials the localized electron is distributed over the four nearest neighbor sites of the impurities with a dominant d(x)(2)-y(2) symmetric form of the wave function. Since both scatterings from the localized electron and the scalar potential are relevant, localized resonant states due to their interplay are formed below the maximal superconducting gap. With Ni impurities, two resonant states are formed above the Fermi level in the local density of states at the impurity site, while for Zn impurities a sharp resonant peak below the Fermi level dominates in the local density of states at the Zn site, accompanied by a small and broad resonant state above the Fermi level mainly induced by the potential scattering. This is exactly what has been observed in the scanning tunneling microscopy experiments. In both cases, there are no Kondo screening effects. From the calculated spin relaxation functions, we find that the 3d localized electron in both Ni and Zn doped materials displays a weak magnetic oscillation. This result is consistent with the signal of a spin-1/2 magnetic moment exhibited by nuclear magnetic resonance measurements in YBa2Cu3O6+delta doped with Zn or Ni impurities. The local density of states and their spatial distribution at the dominant resonant energy around the substituted impurities are calculated for both cases, and they are in good agreement with the experimental results of scanning tunneling microscopy in Bi2Sr2CaCu2O8+delta with Zn or Ni impurities, respectively. Thus the scanning tunneling and nuclear magnetic resonance experiments on Zn and Ni substituted cuprates are interpreted self-consistently in a unified fashion.
Structural fragility and inflammatory response of ruptured cerebral aneurysms. A comparative study between ruptured and unruptured cerebral aneurysms.

BACKGROUND AND PURPOSE Despite technical advances in endovascular and microsurgical treatment, patients with aneurysmal subarachnoid hemorrhage still have a high mortality and morbidity rate. To improve the treatment results in patients with aneurysms, we must better understand the pathophysiology of cerebral aneurysms and the mechanisms leading to their rupture. Therefore, we studied the pathological differences between unruptured and ruptured aneurysms. METHODS Ruptured (n=44) and unruptured (n=27) aneurysms were obtained at surgery. The aneurysmal endothelium was scored from 0 (normal) to 5 (complete disruption) by using a scanning electron microscope. The aneurysmal wall was evaluated by immunohistochemical methods. The wall structure was scored from 1 (dense collagen and rich, smooth muscle cells) to 5 (hyaline-like structure). The degree of inflammatory cell invasion into the wall was also scored from 0 (very few cells) to 3 (many cells). RESULTS Ruptured aneurysms manifested significant endothelial damage (score of 3.7 versus 0.8; Mann-Whitney U test, P<10(-3)), significant structural changes of the wall (3.7 versus 1.7, P<10(-5)), and significant inflammatory cell invasion (2.2 versus 0.8, P<10(-4)) compared with unruptured aneurysms. There was a significant correlation between the score for wall structure and the score for inflammatory cell invasion (Rs=0. 63; Spearman rank correlation test, P<10(-5)). The pathophysiology of several symptomatic unruptured aneurysms was similar to that of ruptured aneurysms. CONCLUSIONS We conclude that the pathophysiology of unruptured, asymptomatic and ruptured aneurysms is different. The wall of ruptured aneurysms was found to be fragile, possibly because macrophage infiltration into the aneurysmal wall resulted in loss of smooth muscle cells and in degradation of matrix proteins.
Self-Anchoring and In-Group Favoritism: An Individual Profiles Analysis

Abstract The current report deals with determinants of in-group favoritism in the minimal group paradigm (MGP). More specifically, valence of comparison dimension and self-evaluations were analyzed as predictors of in-group–out-group evaluations. Self- and intergroup judgments were obtained with regard to a set of positive and negative traits. Data reveal a significant in-group favoritism effect. In addition, there was further evidence for the positive–negative asymmetry in social discrimination; in-group favoritism was stronger on positive than on negative comparison dimensions. Evidence for self-anchoring as the crucial basis for in-group favoritism was found by virtue of individual multiple regression analyses. The self-rating was a better predictor for in-group favoritism than was the valence of the trait. Data imply that a self–in-group generalization, rather than a striving for positive in-group distinctiveness, might underlie in-group favoritism in the MGP, and they demonstrate individual multiple regression analyses as a powerful means to analyze self-anchoring in social judgment.
[Synergistic effect of beta-elemene injection combined paclitaxel injection on human breast cancer MB-468 cells: an in vitro study].

OBJECTIVE To observe the synergistic effect of beta-elemene Injection (betaI) combined Paclitaxel Injection (PI) on breast cancer MB-468 cells and to study possible mechanisms. METHODS Breast cancer MB-468 cells were treated with betaI (2.5, 5.0, 10.0, 20.0, 40.0, 80.0, 160.0, 320.0, and 640.0 microg/mL), PI (0.00100, 0.00200, 0.00400, 0.00800, 0.01600, 0.03125, 0.06250, 0.12500, and 0.25000 microg/mL), and betaI combined PI for 24 h and 48 h respectively. Cell proliferation was determined using SRB assay. Cell apoptosis and cell cycle phase distribution were detected using flow cytometry. The post-intervention expressions of cell cycle proteins [cyclin-dependent kinase (CDK1), cyclin-B1, P21(cip1), and P27(kip1)] were detected by Western blot. RESULTS Beta-elemene or paclitaxel inhibited the growth of MB-468 cell line. The IC50 and IC20 values treated with beta-elemene for 24 h were 34.20 and 52.59 microg/mL and for 48 h were 10.15 and 17.81 microg/mL respectively, while the IC50 values treated with paclitaxel for 24 h and 48 h were 2.449 and 1.698 microg/mL respectively. Beta-elemene (20 and 40 microg/mL respectively) and Paclitaxel (0.016 and 0.008 microg/mL respectively) synergistically inhibited cell proliferation of MB-468 cells, with Q value > 1.15. Beta-elemene alone (52.59 microg/mL) apparently decreased the expression of cyclin-B1 protein. The expression of cyclin-B1 protein in the combined group was also lower than that in the PI group (1.698 microg/mL). The expression of P27(kip1) was up-regulated when compared with that in the betaI group or the PI group. CONCLUSION Beta-elemene had synergistic effect with Paclitaxel, and its possible mechanism might be correlated with down-regulating the cell cycle protein cyclin-B1 expression and up-regulating the P27(kip1) expression.
Comparing perceived experiences of prejudice among self-identified plurisexual individuals

Based on the limited research available regarding bisexual individuals, there is some evidence to suggest this group may be subject to unique forms of prejudice within both heterosexual and lesbian/gay communities. To date, research in this area has relied on samples that do not reflect the diversity of the non-monosexual/plurisexual community. The present study explored the perceived experiences of anti-bisexual prejudice among a diverse group of self-identified bisexual, pansexual, queer and fluid adults (n = 235). Participants completed an online self-report survey containing 50-items concerning experiences and expressions of sexual orientation and gender identity. Results from the Anti-Bisexual Experiences Scale revealed bisexual participants reported more experiences of sexual prejudice from lesbian/gay individuals than did pansexual/queer/fluid participants. Exploratory analyses based on this finding revealed bisexual individuals also reported less subjective connection to the lesbian, gay, bisexual and transgender community than did pansexual/queer/fluid individuals. This factor, however, did not account for differences in experiences of sexual prejudice from lesbians/gay individuals. These findings challenge the grouping together of all plurisexual individuals under the label bisexual and underscore the importance of interpersonal context in the experience of sexual prejudice.

Some effects of audio and visual stimulation on multiple forms of stereotypy

Three experiments were conducted to evaluate the effects of audio and visual stimulation, alone or in combination, on the behavior of three children who displayed multiple forms of stereotypy (e.g., hand mouthing, body rocking). The results of experiment 1 showed that all three participants displayed different forms of stereotypy when audio and visual stimulation were provided versus when no stimulation was provided. The results of experiments 2 and 3 showed that the form of one participant's stereotypy, but not the other two, changed when visual stimulation and audio stimulation were presented separately. Overall, the results suggest that ambient stimulation may influence both the form of and time allocation to stereotypy. Copyright © 2005 John Wiley & Sons, Ltd.
