Towards a Novel Graph-based collaborative filtering approach for recommendation systems

Recommendation systems have become an entrenched part of emarket platforms as they help offer personalized user experience, increasing thus loyalty, satisfaction and lifetime value. Although great effort has been devoted to the proposal, implementation and study of recommendation systems approaches, there is still a lot of room for improvement. This work proposes a novel Graph-based Collaborative Filtering approach for recommendation systems. The key idea is to improve the accuracy of Hybrid approaches by basing recommendations on a more refined Homophily (similarity) level. We hypothesize that a user-base is a network of highly similar sub-communities and that any inference should be made on these communities' level rather than on the whole user-base. Furthermore, some users are more embedded in these similarity communities than others. We think that these "Key-nodes" can lead to more accurate recommendations than the ones based on aggregations on similar users. The paper also presents a validation of our approach and the computation of the accuracy of its underlying model over the classical MovieLens dataset. The experiment's results indicate significant gain in performance compared to two classical recommendation systems' approaches.
A Study on the Validity Evidence of the Pre-Professional Skills Test (PPST) as a Screening Device for Entrance into Teacher Education Programs.

This study examined aspects of concurrent, predictive, and consequential validity evidence of the Pre-Professional Skills Test (PPST) scores as college of education admission criteria. American College Test (ACT) and PPST subtest scores of 372 graduates, and PPST scores, undergraduate grade-point averages, and student teaching ratings of 1,062 graduates of a southwestern urban teacher education program were investigated. Findings of a correlation and hierarchical regression analyses suggest that there is evidence of a concurrent relationship between corresponding PPST and ACT subtest scores, no predictive relationship between PPST scores and student teaching ratings, and a weak predictive relationship between PPST scores and student undergraduate grade-point averages. In addition, a differential impact of the use of the PPST on ethnic minorities is apparent. The plausibility of waiving the PPST requirements for applicants with above average ACT subtest scores is discussed. (Contains 5 tables and 36 references.)

Comparison of central macular thickness by optical coherence tomography (OCT) in normal and diabetic patients without diabetic retinopathy

Optical coherence tomography provides a high-resolution imaging of ocular tissues to improve the diagnosis and management of diabetic retinopathy by producing reliable, reproducible and objective retinal images especially in diabetic macular edema that can clearly only be detected with OCT. It enhances the ability to exactly diagnose diabetic macular edema, epiretinal membranes, vitreomacular or vitroretinal traction. OCT also helps in visualising morphological changes of the retina in diabetic retinopathy. It demonstrates that macular edema which is a complex clinical entity with various morphology. With the OCT, structural changes and quantitative assessment of macular edema have become feasible as determined with retinal thickness and volume. Keywords: OCT, Diabetic retinopathy.
Genetic distinctiveness of Masked Booby (Sula dactylatra) on Bedout Island, Western Australia

ABSTRACT The Masked Booby is a highly vagile, pantropical seabird of which up to six subspecies have been recognised: S. d. dactylatra, S. d. californica, S. d. personata, S. d. melanops, S. d. bedouti and S. d. tasmani. The genetic distinction of several S. dactylatra colonies has been previously investigated, but this has not yet been conducted for the Bedout Island population in Western Australia, which has been considered by some to be part of a distinct subspecies. Suspected population decline on Bedout Island has renewed interest in determining the extent to which genetic novelty might be threatened. To answer this question, morphological and mitochondrial control region sequence variation were used to determine the distinction of the Bedout Island population. Whereas the morphological measures were equivocal, six haplotypes were identified from 31 individuals, none of which were shared by individuals previously sampled from the Indo-Pacific. The Bedout Island haplotypes were most closely related to other haplotypes found in a distinct Indian Ocean haplogroup, but haplotype frequencies at Bedout Island differed significantly from all other. This indicates that the Bedout Island population rarely exchanges mitochondrial genes with any of the other Masked Booby colonies presently studied, which may reflect dependence on local recruitment for its persistence.
Dual Band Notched UWB MIMO Antenna for Surfaces Penetrating Application

This paper introduces a novel compact planar Ultra-Wideband (UWB) Multiple-Input-Multiple-Output (MIMO) antenna with dual-band notched performance for Surfaces Penetrating (SP) application. To avoid interference from co-existing systems, two notched bands are introduced by including strips inside the radiating patches. The two ports MIMO antenna is printed on the low-cost FR4 substrate having a compact size of 56×32.47×1.5 mm3. The measured results indicate that the −10 dB bandwidth of the proposed MIMO antenna covers a wide bandwidth from 1.57 GHz to 12.4 GHz (155.05%) with dual-band rejection (2.04 GHz – 3.98 GHz and 4.8 GHz – 6.22 GHz). The effects of numerous construction and decoration surfaces on the antenna’s reflection coefficients are measured. Gypsum, White Portland Cement, Slate, Marble, Wood and Reinforced Concrete were tested. A good penetrating capability is measured which confirms the aptitude of the proposed MIMO antenna to work as SP antenna.
Consumption in the Great Recession: The Financial Distress Channel

During the Great Recession, the collapse of consumption across the US varied greatly but systematically with house-price declines. Our message is that household financial health matters for understanding this relationship. Two facts are essential for our finding: (1) the decline in house prices led to an increase in household financial distress (FD) prior to the decline in income during the recession, and (2) at the zip-code level, the prevalence of FD prior to the recession was positively correlated with house-price declines at the onset of the recession. We measure the power of the financial distress channel using a rich-estimated-dynamic model of FD. We find that these channels amplify the aggregate drop in consumption by 7% and 45%, respectively.
The Role of Magnetic Resonance Imaging ın Diagnosis of Arrhythmogenic Right Ventricle Dysplasia

Objectives Arrhythmogenic right ventricle dysplasia and cardiomyopathy (ARVD/C) occurs due to fibrofatty tissue infiltration in the ventricle myocardium. It is characterized with structural and functional abnormalities, mostly involving the right ventricle and the anterolateral part or the septum. Although the etiology has not been completely understood, it is responsible for the sudden death in early adolescents and athletics. The objective of this article is to demonstrate the accuracy of ARVD/C findings in clinically confirmed ARVD/C cases by cardiac magnetic resonance imaging (MRI). Material-Methods Cardiac MRI findings of clinically diagnosed 23 ARVD/C patients (18 male, 5 female; mean age: 38.2; SD: ± 13) were evaluated retrospectively. In four chamber (4CH) cine images at both end-diastolic and end-systolic phases of cardiac cycle, the endocardial diameters of both atria and ventricles were measured. Results Findings were found as following: right ventricular dilation at end-diastolic phase (> 42 mm: 78.2%) , right atrial dilation (> 41 mm: 78.2%) , myocardial fatty replacement ( 74%) and left ventricular dilation (> 42 mm: 74%) , ventricle wall motion disorders on Cine MRI (43.5%) , decrease in myocardial contractions (30.4%) , post-contrast enhancement due to fibrosis (21.7%) , right ventricle outflow tract dilation (21.7%) , trabeculation (17.4%) . Tricuspid insufficiency was 4.3% and Ebstain’s anomaly was found as 4.3%. Conclusion MRI is useful for the diagnosis of ARVD/C. In the current study, the most frequent MRI findings were right ventricular and atrial dilation, myocardial fatty infiltration and left ventricular dilation respectively. The presence of fibrosis is significant for the diagnosis of ARVD/C. The left ventricle involvement is rare and may occur in ARVD/C, therefore, the fatty replacement areas of left ventricle should be evaluated carefully.
Relationship between triclosan exposure and thyroid hormones: the Second Korean National Environmental Health Survey (2012–2014)

Background 5-chloro-2-(2,4-dichlorophenoxy)phenol (triclosan) is used as an antiseptic and is a potential endocrine-disrupting chemical that can affect thyroid hormone levels. This study evaluated the relationship between triclosan exposure and thyroid hormones. Methods Data from the second Korean National Environmental Health Survey (2012–2014) were analyzed. Triclosan exposure was evaluated using urinary triclosan concentrations and classified into 2 groups: ‘below detection (< limit of detection [LOD])’ vs. ‘detected (≥ LOD). ’ Multiple linear regression analysis was conducted to determine the relationship between triclosan exposure and the serum thyroid hormone concentrations, adjusting for age, body mass index, urinary creatinine, and smoking status. Results When grouped by sex, triclosan exposure was positively associated with the serum thyroid-stimulating hormone (TSH) concentrations in females with marginal significance (β = 0.066, p = 0.058). However, no significant association was identified between triclosan exposure and serum total triiodothyronine and thyroxine in both males and females, and TSH in males. Conclusions This study is the first human study to evaluate the relationship between triclosan exposure and serum thyroid hormone concentrations in the Korean population. There was suggestive positive association between triclosan exposure and the serum TSH in females. Further studies need to evaluate the relationship between long-term exposure to low-dose triclosan and thyroid hormones.

THE RELATIONSHIP BETWEEN ACADEMIC AND CAREER COUNSELING AND PERSISTENCE IN HIGHER EDUCATION.

The purpose of this study was to determine if first year students in higher education who participated in pro­ grams of academic and career counseling experienced a higher rate of persistence as opposed to a similar group of students not participating in counseling, using data from the National Longitudinal Study of the High School Class of 19 72. A partial correlation analysis was used to determine the net correlation of academic and career counseling on persistence with the effects of the other variables in the battery accounted for. These other variables were high school grade point average, self-concept, race, sex, and socioeconomic status. The findings allowed the researcher to reject the null hypothesis. The partial correlation coefficient was . 0243 at . 016 level of significance. In conclusion, further research into the effects of counseling on persistence could lead to programs of benefit to students, counselors, and administrators.
Temperature effects on exploratory behaviour and learning ability of invasive mosquitofish

The success of an invasive species depends on several factors. One of these is behavioural flexibility, which may promote invasions by allowing invaders to exploit novel foods, habitats and shelters. As behaviour can change rapidly it is an ideal first response to environmental change, including introduction and spread into a new habitat. Behaviour can be modified by learning, thus facilitating adjustment of existing behaviours to accommodate environmental conditions. Climate change is also likely to promote the introduction, establishment, and spread of aquatic invasive species. Temperature in particular is vitally important for ectotherms, directly affecting metabolic rates with consequent changes in behaviour. We evaluated the effects of temperature on the exploration tendency and learning ability of the western mosquitofish, Gambusia affinis. After acclimating fish to warm, medium and cool temperatures we showed that behaviour is affected by temperature, and overall warm-acclimated fish outperformed lower temperature fish. Mosquitofish showed remarkably rapid learning ability exhibiting a clear change within just three days. These effects also differed by fish sex and size. In general, larger females and smaller males were quicker to approach a novel object, while smaller females and larger males were quicker to find food. Warm-acclimated fish learned to adjust to a novel object more quickly and warm-acclimated males showed a faster response to food. In contrast, neither males nor females acclimated to warm temperatures appeared to learn to find the food and it was cool-acclimated females who were both faster to find food and showed the greatest improvement over time. Nonetheless, on both local and global scales, mosquitofishes’ rapid learning ability and behavioural flexibility, which allows them to adjust to changing temperatures, is likely to augment their success as invaders in a warming world.
Serotyping and antimicrobial sensitivity of Escherichia coli isolated from gastrointestinal tract disorders in sheep.

A total of 30 sheep received for necropsy over a period of 6 months were thoroughly examined. Seventy two tissue samples were collected from 30 sheep showing the gross pathological lesions of gastrointestinal tract disorders. Out of which, 48 confirmed isolation of E. coli based on culture characteristics and biochemical tests and 14 sheep were found E. coli positive. Infection was prominent in less than one year age groups and more in male sheep. Out of 48, only 18 strains were sent for serotyping. Out of which, 13 belonged to ‘O’ serogroup, whereas remaining five isolates were untypable strains. The most prevalent serotype was O168(5) followed by O60(4), O1(1), O91(1), O102(1) and O116(1). Invitro drug sensitivity pattern by the single disc diffusion method revealed maximum sensitivity to polymixin B, ofloxacin, amikacin, ampicillin, colistin, furoxone, amoxycillin+clavulanic acid, cefixime, amoxicillin, amoxycillin+sulbactum, doxycycline, ciprofloxacin, cefpodoxime, co-trimoxazole and nalidixic acid in decreasing order.
The influence of resistant soybean cultivars on the biological development of Euschistus heros (Hemiptera: Pentatomidae)

ABSTRACT Two stink bug-resistant soybean cultivars, Dowling and IAC 100, and one sucepible, Silvânia were selected to evaluate their influence on Euschistus heros development. Evaluation of the biology of E. heros was conducted on nymph development, adult longevity, female fecundity and egg fertility in seeds of each cultivar. The results showed that E. heros nymphs reared on cv Dowling did not complete their biological cycle, but it was completed on cvs Silvânia and IAC 100. The total amount of six isoflavonoids identified and one flavonol was higher in cv Silvânia compared to the levels quantified in cv Dowling. The results showed that cvs Dowling and IAC 100 have constitutive resistance affecting E. heros development and that the major falvonoids quantified in these cultivars are not involved in soybean antibiotic effect observed in this study.
Effect of Natural Antioxidants Supplementation as Feed Ingredients in Laying Hen Diet

This study was conducted to elucidate the effect of two types of antioxidants containing compounds on some physiological components of laying hens for 8 weeks as well as egg quality with special reference to egg yolk cholesterol concentration. Ninety six adult Shaver White laying hens were randomly divided into six groups ,each contained sixteen birds , control group, two garlic groups ( fed on basal diet plus 1g or 3g/kg), two yeast groups (fed on basal diet plus 2g or 4g /kg), and the last group received basal diet plus a mixture of 3g garlic and 4g yeast /kg. Feed intake significantly increased in groups received garlic (3g/kg) and that received garlic and yeast together, while egg weight , Haugh unit and egg mass, were not significantly affected but egg production percent significantly improved . Egg yolk cholesterol significantly declined in all treated groups, especially in that given both garlic and yeast. serum total lipids, triglycerides, cholesterol as well as LDL-C significantly declined in most treated groups while serum HDL-C significantly increased in the groups receiving garlic (3g/kg) or both garlic and yeast. Also serum total protein and albumin levels increased in the group supplemented with both garlic and yeast. Serum levels of estrogen and progesterone significantly increased in the group receiving both garlic and yeast. In conclusion dietary garlic and yeast powder can be used for laying hens to increase egg quality , since, they have a cholesterol-lowering effect.
Kiwisaver Member Behaviour: A Quantitative Analysis

The KiwiSaver scheme for retirement savings was launched in New Zealand in 2007. This paper examines investor behaviour in the context of that scheme. It uses a unique purpose-built database. The study finds that KiwiSaver members, like other investors, are chasing performance and seeking to avoid fees. However, an unexpected negative relation is found for bank ownership.
The effect of social and ecological factors on the time budget of wild vervet monkeys

Animals often have a limited time to perform different fitness-enhancing activities, such as the trade-off between socializing versus foraging in group-living species. Many previous studies have focused on how ecological and social factors influence activity budget at the individual or group level in various species. However, few primate studies have focused on multiple study groups living within a similar habitat. Here, we analyse group, season and sex effects on the individual activity budget of wild vervet monkeys (Chlorocebus pygerythrus) living in four groups with overlapping home ranges. Generally, our findings support previous studies on primates. Our results indicate that intragroup competition may force larger groups to spend more time feeding and less time resting. We also found that seasonal variation, and therefore food availability, has a strong influence on the monkeys’ activity budget. Females, which are the philopatric sex in vervet monkeys, spent more time socializing while, in general, males spent more time resting. However, we did not find any difference on the time spent socializing between groups. Since there is evidence that not only time constraints and habitat quality but also group size influence individual behaviours and ultimately group living, we advise that future studies should focus on multiple groups of the same species living in the same habitat in order to better understand how all these variables are interlinked.
A comparison of mammography, ultrasonography, and far-infrared thermography with pathological results in screening and early diagnosis of breast cancer

Abstract Background: Many breast-imaging techniques have been developed as primary clinical methods for identifying early-stage breast cancers and differentiating them from benign breast tumors. For the large population of China, any screening method that is rapid, economical, and accurate is worthy of evaluation. Objective: To compare the effectiveness of mammography, color Doppler ultrasonography, and far-infrared thermography in the screening and early diagnosis of breast cancer. Methods: Data from 2036 women with breast disease between January 2007 and May 2011 were included in this study. All patients underwent mammography, ultrasonography, and far-infrared thermography imaging. The diagnostic accuracy of the three methods was determined using postoperative pathological results as the diagnostic criterion standard. Results: There were 480 patients found to have breast malignancies on pathological examination. The lesion diameter was <2 cm in 853 cases. Among them, breast cancer was found in 73 patients and carcinoma in situ in 22 patients. There was no difference in the accuracy of mammography and ultrasonography (96.1% versus 95.8%). However, there were significant differences between the accuracy of far-infrared thermography (97.1%) and ultrasonography and mammography. The sensitivity and specificity of far-infrared thermography was superior to that of mammography and ultrasonography in lesions <2 cm in diameter. Conclusion: Far-infrared thermography is more accurate for breast cancer screening than ultrasonography and mammography for lesions <2 cm. It has comparable diagnostic accuracy to ultrasound and better diagnostic accuracy than mammography for lesions >2 cm in diameter.
