Addressing the cold-start new-user Problem for Recommendation with Co-training

—Many online domains rely on recommender systems for personalization of the content offered to their customers. In order to personalize the content for the user, recommender systems rely on user’s rating history. When a new user is joining the system, the lack of rating history is a serious problem for building a personalized model. In this paper we strive to alleviate this new-user problem by reducing the number of user’s ratings needed for quality recommendation. We pose the recommendation problem as a classification problem: for each user a separate classification model is trained. Given the item unrated by that user, this model predicts whether the user will like or dislike the item. In order to alleviate the new-user problem, we employ the semi-supervised co-training algorithm. The co-training algorithm assumes a multi-view setting (i.e. a defined split of features in the dataset). In this paper we propose to use features based on users’ ratings as the first view and item description (content features) as the second view. We perform our experiments on a popular MovieLens dataset, and show that, by using co-training, for the users that have rated very few items; we can achieve the performance a supervised system would have, given a huge rating history for that user.

Objective:A ion-suppression reversed-phase HPLC method was established for the determination of rudimental L-malic acid and Shikimic acid in Taxodium aseendems and T axodium distiehum.Methods:They can be separated on Agilent 1100 DAD and Hypersil ODS2 5μm,(4.6 mm×150 mm)column by using perehloric acid (pH=2.25)as mobile phase with UV detector at a wavelength of 214 nm.Results:The standard curve of L-malic acid and shikimic acid was linear in the concentration range 7.16×10~(-6)mol·L~(-1)-2.24×10~(-2)mol·L~(-1) and 1.27×10~(-7) mol·L~(-1)-2.06×10~(-4)mol·L~(-1)and the correlation coefficient was 1.0000 and 0.9999. The detec- tion limit was 2.42×10~(-8) mol·L~(-1) and 1.16×10~(-9) mol·L~(-1)(S/N=3). Conclusions:The method has been suc- cessfully applied to the determination of trace rudimental L-malic acid and Shikimic acid in the root of Taxodium ascendens and Taxodium distiehum,which was proved to be accurate,simple effective and feasible.
ANALYSIS AND IMPLEMENTATION OF PARALLEL AES ALGORITHM BASED ON T-TABLE USING CUDA ON THE MULTICORE GPU

: The Advanced Encryption Standard (AES) is used in security areas widely now. However, there is still a large room for further improvement of its execution efficiency. GPUs are very efficient at manipulating computer graphics and image processing, and their highly parallel structure makes them more efficient than general-purpose CPUs for algorithms where the processing of large blocks of data is done in parallel. In this paper, a design of parallel AES on the multiprocessor platform is presented. Our design is based on combining the steps of MixColumn, SubstituteBytes and AddRoundKey using the concept of T-Table. In order to enhance the throughput of AES algorithm, it is implemented parallel on multicore GPU which uses SIMD architecture using CUDA which is the framework for writing program using C++.
Preservice teachers’ perception of longitudinal child development field coursework at a university-affiliated teaching school

Background: Most field coursework in teacher education (TE) programmes do not incorporate extended in situ interaction with individual children in a classroom. Furthermore, child development theory (from coursework) is not taught in tandem with students’ extended periods of practicum placement in schools. Aim: This study sought to determine preservice teachers’ perception of their longitudinal study of children’s development and learning in a clinical setting at a university-affiliated teaching school. Setting: This study focusses on two undergraduate primary school TE programmes at an urban university in Johannesburg, South Africa. These programmes incorporate six semester courses on child development with extended clinical field experience at a teaching school on campus. Each student teacher follows a particular child’s development and learning over four years of their undergraduate coursework. Methods: This was a qualitative descriptive study with some cross-sectional data. Data were collected from 120 undergraduate students, by using anonymous questionnaires and four focus group interviews. Results: Students reported that they had gained in-depth learning of child development during their longitudinal pairing with an individual child and that assigned observation activities had taught them to recognise, and support, nuanced differences in a child’s learning. Conclusion: Students regard their longitudinal interaction and learning in the clinical setting positively. Future research should focus on the long-term value of the clinical model with insights from students who have graduated from the programme and are in the teaching profession.
Effects of Perceived Organisational Support and Emotional Intelligence on Turnover Intention among Logistics Drivers

The turnover trends in the logistics industry are surprisingly high, regardless of the rapid growth of the industry. Turnover contributes to an impactful loss for the industry to tolerate the new recruitment costs, time consumption, performance disruption, and moral decline among employees due to the workload transfer. Previous literature presented various factors affecting turnover intention, and it could be concluded that factors within an organisation and individual play an essential role in turnover actions. Hence, this research focuses on perceived organisational support and emotional intelligence as factors to turnover intention among logistics drivers in Selangor. Eighty respondents from POS Logistics Berhad in Selangor participated in self-administered survey questions of Survey Perceived Organizational Support, Wong and Law Emotional Intelligence Scale, and Turnover Intention Scale. Results revealed that most of the respondents have a moderate level of POS (84%) and a high level of EI (91%). In comparison, slightly half have a low level of TOI (56%). Research also found that POS and EI have no significant relationship with turnover intention, which is contrary to previous literature. Similarly, three criteria of EI; self-emotion appraisal, uses of emotions, and others-emotions appraisal also have no significant relationship with turnover intention. Only regulations of emotions (r=0.024, p=0.031) has significant relationship with turnover intention. Since the current study location was restricted for a few branches of Pos Logistics in Selangor, it limits the result of the study due to misrepresent the whole community fairly. Future researchers are encouraged to extend or increase the sampling size to other companies and regions to make better generalisations.
Isolation and Identification of Facultative Anaerobes in the Pit Mud of Chinese Luzhou-flavor Liquor

In order to know the composition of bacterial community in the pit mud of Luzhou-flavor liquor,and to study further the relationship between microbial diversity and liquor characteristics,traditional microbial classification and identification methods were carried out to analyze the culturable facultative anaerobes in the mud samples from both bottoms and walls of the pits of different ages.The bacterial strains were identified to genus according to their morphological,physiological and biochemical characteristics.Counted by using dilution-plate method,the total amount of bacterial colonies in the bottom of older pit was found to be the highest,reaching to 3.98 10 3 cfu/g mud.While the least was found in the wall of younger pit,only 0.24 10 3 cfu/g mud.So the older the pit mud is,the bigger the bacterial community is.The result of identification showed that most of the strains isolated from pit mud belong to the genera Bacillus and Sporolactobacillus,those belong to genera Mycobacterium,Pseudomonas,Microbacterium,Corynebacterium,Flavobacterium and Clostridium were also existent.
The Impact of Node Density and Buffer Size on DTN Routing Protocols with Energy Efficiency

Delay Tolerant Network (DTN) architecture comprises of portable devices known as nodes, considered a resource-limited networking system. These nodes in DTN utilize the ‘Store Carry and Forward’ approach to route data since the end to end connections are absent here due to a large number of constant intermittent connectivity. The energy quantity of nodes is restricted because limited-lifetime rechargeable batteries drive them. Accordingly, energy is an essential resource in DTN scenarios. For efficient network performance, including proper energy usage, nodes need to expense a minimum amount of energy. For this reason, it is essential to select an energy-efficient forwarding strategy and exhibit excellent performance among existent forwarding approaches in the DTN environment for routing messages effectively. In this paper, we have studied the energy efficiency of conventional DTN routing protocols: Epidemic, Spray and Wait, Spray and Focus, MaxProp, and PRoPHET on the impact of varying both buffer size and node density. We analyzed their energy consumption and compared their performance based on five performance metrics: average remaining energy, delivery ratio, average delay, transmission cost, and average hop count, respectively. Using ONE simulator, we performed a simulation with varying node density (while buffer size is fixed) and varying buffer size (while node density is fixed). From the outcomes of simulation, we found that Spray and Wait are the most energy-efficient DTN routing protocols. On the contrary, Spray and Focus possessed as the best performer in terms of average hop count, average delay, delivery ratio and transmission cost among conventional DTN routing protocols.
Studies on Photosynthetic Rate and Function Duration of Rice Germplasm Resources

Two hundred and thirty rice germplasm resources were used to analyse their photosynthetic rates (P n) and function duration (RSP). The results showed that the variation coefficient of P n and RSP of individuals within a rice variety was 2 0%-11.0% and 3.5%-9.5%, but it was 11.1% and 11.2% among rice varieties, respectively. Analysis of statistics with experimental results showed that the difference of P n and RSP among rice varieties was significant at 1% level, but not between indica and japonica rice. The numbers of indica rice with high P n and japonica rice with long RSP were relatively more. According to the clustering results, 42 rice varieties were separated into three groups, i.e. high, middle and low of P n and RSP, respectively. Two dimension compositor was made in rice varieties for P n and RSP, and this coordinate was divided into 4 quadrants. The distribution frequency of indica and japonica rice varieties was the highest in the second and first quadrant, respectively. Some rice varieties regarded as special photosynthesis resources were screened out, such as Xieyou 9308, Lunhui 422, Wuyujing 8, NPT, Shanyou 129. They might be used to optimize rice crossing and study photosynthesis heredity improving in rice.
A Welfare State Paradox: State Interventions and Women’s Employment Opportunities in 22 Countries1

This study explores the role played by the welfare state in affecting women’s labor force participation and occupational achievement. Using data from 22 industrialized countries, the authors examine the consequences of state interventions for both women’s employment patterns and gender inequality in occupational attainment. The findings reveal a twofold effect: developed welfare states facilitate women’s access into the labor force but not into powerful and desirable positions. Specifically, nations characterized by progressive and developed welfare policies and by a large public service sector tend to have high levels of female labor force participation, along with a high concentration of women in female‐typed occupations and low female representation in managerial occupations. The findings provide insights into the social mechanisms underlying the relations between welfare states’ benefits to working mothers and women’s participation and achievements in the labor market.
Novices’ performance using hypertext materials: Shedding light on disorientation

Many researchers have proposed a causal link between low domain knowledge and disorientation in hypertext. Our objective was to challenge this hypothesis, examining other variables that might have an influence, such as design, reading instructions, or working memory capacity. We analysed navigation patterns and comprehension scores in a sample of low topic knowledge undergraduate students (N = 45) who were assigned to one of three hypertext conditions: reading for a test, reading to write a summary, and elaborative interrogation. Another sample (N = 45) of low knowledgeable undergraduate students were used as a control group, performing the same tasks using printed texts. Regarding disorientation, and contrasting with previous research, only a minority of students became disoriented in hypertext. Neither reading instructions nor working memory capacity had the expected impact on readers’ behaviour or outcomes, so hypertext design might be a key aspect on explaining disorientation. Implications for hypertext design and education are discussed.
STANDARDISED ILEAL AMINO ACID DIGESTIBILITY OF SELECTED FEEDSTUFFS IN BROILER CHICKEN

Standardised Ileal Amino Acid Digestibility (SIAAD) of maize, wheat, soybean meal (SM), groundnut cake (GC) and rice bran (RB) in broiler finisher diets was investigated. Three hundred and sixty 35-day old Arbor Acre broiler chicks were randomly allotted to a Nitrogen-Free Diet (NFD) and five semi-purified diets containing each of the test feedstuffs (maize, wheat, SM, GC and RB) as the sole source of protein. Diets were fed to ten birds of six replicates up to day-42 in a randomised complete block design. Chromic oxide (5 g/kg) was added to the feed as an indigestible dietary marker. Six birds per replicate were asphyxiated with CO2 and digesta samples were collected from terminal ileum on day 42. The endogenous amino acid losses (EAAL), apparent ileal amino acid digestibility (AIAAD) and SIAAD were estimated. Highest EAAL concentration was found in threonine (0.29g/kg), while glutamic acid and alanine (0.03g/kg) had the least. Total AIAAD were 69.47, 59.49, 70.48, 73.04 and 62.21%, in maize, wheat, SM, GC and RB, respectively. Correspondingly, total SIAAD were 70.86, 61.30, 71.76, 75.13 and 64.05%. Least SIAAD values of amino acids were recorded in wheat compared to the other feedstuffs. Isoleucine had the highest increase in wheat and GC with 3.1 and 3.73%, respectively. In SM and maize, threonine had the lowest increase with 8.0 and 0.94%, respectively. Average increase of SIAAD over AIAAD for indispensable amino acid was 1.58, 1.95, 1.37, 2.24 and 2.10% for maize, wheat, SM, GC and RB respectively. Results from the present study showed that correcting AIAAD for endogenous losses using nitrogen-free method resulted in increased digestibility values for all the feedstuffs.
Clinical, Morphological and Molecular Characterization of Canine Babesiosis and its Compatible Tick Vector in Naturally Infected Dogs, in Egypt

The low scientific attention in dealing with dog diseases is still present comparing to other animal species in Egypt in spite of its wide spreading as pets, hunting dogs or for other purposes. Canine babesiosis is a haemoprotozoal parasitic disease inducing significant clinical manifestations on the infected dogs. The present study aimed to accurately identify the causative species of canine babesiosis in naturally infected dogs in Egypt and its compatible tick vector. For this purpose 75 dogs including 19 dogs at Sharkia and 56 dogs at Dakahlia Governorates, Egypt were clinically examined and 20 (26.67%) dogs showed signs of fever, weakness, anorexia, pale mucous membrane and different degrees of anemia. During examination, there were 8 dogs had variant degrees of tick infestation. Further parasitological identification of 50 collected ticks showed that all the collected ticks were belong to Rhipicephalus sanguineus (R. sanguineus) species. Whole blood samples collected from all examined dogs were screened by thin blood film for presence of Babesia species piroplasm. Nine samples (12.0%) showed pyriform shaped protozoa inside red blood cells (RBCs). All blood samples and 5 pooled tick samples (10 ticks/each) were screened against 18s rRNA of Babesia species genome using semi-nested polymerase chain reaction (PCR). Babesia canis vogeli (B. canis vogeli) was the only detected species in fourteen blood samples (18.67%) and all collected tick samples. It is the first study in Egypt to use semi-nested PCR for detection of 18s rRNA of canine babesiosis in ticks collected from naturally diseased dogs.
Nonexistence and Aboutness: The Bandersnatches of Dubuque

Holmes exists is false. How can this be, when there is no one for the sentence to misdescribe? Part of the answer is that a sentence’s topic depends on context. The king of France is bald, normally unevaluable, is false qua description of the bald people. Likewise Holmes exists is false qua description of the things that exist; it misdescribes those things as having Holmes among them. This does not explain, though, how Holmes does not exist differs in cognitive content from, say, Vulcan does not exist. Our answer builds on an observation of Kripke’s: even if Holmes exists, he is not in this room, for we were all born too late.
DEVELOPMENT OF CEREAL BARS USING BACURI PULP FLOUR FOR SPORTSMEN: NUTRITIONAL COMPOSITION AND SENSORY ACCEPTABILITY

The objective of this study is to develop and analyze the sensorial acceptability of cereal bars using bacuri pulp targeting the sports public. Formulations using different concentrations of bacuri flour were prepared: F1 (0%), F2 (10%) and F3 (20%). The formulations were submitted to microbiological analysis, centesimal composition and vitamin C. In the sensorial analysis, the attributes were evaluated with 107 athletes from Campo Grande MS. Statistical analyses using the SPSS software were performed, considering p<0.05. In the physical-chemical characterization of cereal bars, carbohydrate and protein contents were F1 = 67.47% and 11.66%, F2 = 68.26% and 10.31%, F3 = 68.41% and 9.29%, respectively. The bars F1, F2 and F3 presented 1.27 mg, 2.12 mg and 3.38 mg of vitamin C in 100 g. The formulations were suitable for microbiological legislation. The formulation F2 presented an acceptability index of 82.2% in global acceptance, and was significantly superior to the others in all attributes. None of the formulations were rejected, with acceptance rates above 70%. The development of differentiated cereal bars aims to improve nutritional and functional composition for the sports public and athletes using regional ingredients such as bacuri pulp to generate innovation and nutritionally benefit consumers.
Effect of feeding mixture of garlic bulb and peppermint oil on methane emission, rumen fermentation and microbial profile in buffaloes

Feeding of a mixture of two plant products (25 g garlic bulb mixed with 1ml peppermint oil; GP) was tested for its effect on methane production, rumen fermentation and microbial profile in 4 rumen fistulated buffaloes given a ration containing 50% wheat straw and 50% concentrate mixture in 2x2 switch over design. The animals of one group served as control, and the diet of animals of other group (GP) was supplemented with GP @ 2.5% of the DM intake. The supplementation of GP did not show any affect on dry matter intake, digestibility of dry matter (DM), organic matter (OM), neutral detergent fibre (NDF), acid detergent fibre (ADF) and ether extract (EE). The rumen pH, concentration of ammonia nitrogen, lactic acid and activities of carboxymethylcellulase and xylanase were also similar in both the groups. The population density of total bacteria, fungi, Fibrobacter succinogenes and methanogens and protozoa was also similar in both the groups. The inclusion of GP in the diet resulted in 13.0% reduction in methane production (l/day), but when expressed as l/kg DMI the inhibition was 7% as compared to the control animals. The results indicated that the use of mixture of garlic bulb as feed additive can be explored to mitigate methane production in buffaloes.
TO STUDY THE EFFICACY OF POST BRONCHOSCOPY SPUTUM IN ADDING TO THE YIELD OF BRONCHIAL WASHINGS IN DIAGNOSIS OF ACID FAST BACILLI

Introduction: Sensitivities for positive BAL culture of Mycobacterium tuberculosis vary from 44 to 95%. Thus, a proportion of patients with PTB will remain undiagnosed by BAL alone. Little is known about the clinical utility of sputum sampling after bronchoscopy and its diagnostic potential in smear negative PTB suspects. This study aims to study the efficacy of post bronchoscopy sputum in adding to the yield of bronchial washings in diagnosis of AFB. Aim: To study the efficacy of post bronchoscopy sputum in adding to the yield of bronchial washings in diagnosis of acid fast bacilli. Methodology: Retrospective study Results: The combination of bronchial washings and post bronchoscopy sputum examination is superior to bronchial washing examination alone in the detection of acid fast bacilli. Conclusion: The study proves the efficacy of post bronchoscopy sputum examination in adding to the yield of bronchial washings examination in diagnosis of acid fast bacilli.

The Constructs of Leadership, Management and Regulation in Education

Leadership, management, and regulation are expressions that translate processes taken in schools. However, contexts characteristics are determinant for these practices and schools are complex and surprising environments, which should mobilize concepts, tools, and strategies different from those used in orderly and predictable environments. Thus, I discuss the constructs of leadership, management, and regulation from the premise that schools are complex adaptive systems, namely that interactions lead because they are capable to promote novelty and adaptations in the organization, formal(executive) leadership is based on the power to change interactions rather than individuals; management should be geared to handling the conditions of interaction between agents - which does not exclude the need to effectively manage other resources; and regulation is defined by the stimuli to coherence - and not so much by the stimuli to conformity. It is concluded that, since the educational policies structure the forms of relationship between the agents are, also, policies of interaction.
