A novel approach for feature selection method TF-IDF in document clustering

Now a day, the text document is spontaneously increasing over the internet, e-mail and web pages and they are stored in the electronic database format. To arrange and browse the document it becomes difficult. To overcome such problem the document preprocessing, term selection, attribute reduction and maintaining the relationship between the important terms using background knowledge, WordNet, becomes an important parameters in data mining. In these paper the different stages are formed, firstly the document preprocessing is done by removing stop words, stemming is performed using porter stemmer algorithm, word net thesaurus is applied for maintaining relationship between the important terms, global unique words, and frequent word sets get generated, Secondly, data matrix is formed, and thirdly terms are extracted from the documents by using term selection approaches tf-idf, tf-df, and tf2 based on their minimum threshold value. Further each and every document terms gets preprocessed, where the frequency of each term within the document is counted for representation. The purpose of this approach is to reduce the attributes and find the effective term selection method using WordNet for better clustering accuracy. Experiments are evaluated on Reuters Transcription Subsets, wheat, trade, money grain, and ship.
Multiracial Parents: Mixed Families, Generational Change, and the Future of Race

The world’s multiracial population is considered to be one of the fastest growing of all ethnic groups. In the United States alone, it is estimated that over 20% of the population will be considered “mixed race” by 2050. Public figures—such as former President Barack Obama and Hollywood actress Ruth Negga—further highlight the highly diverse backgrounds of those classified under the umbrella term of “multiracial. ” Multiracial Parents considers how mixed-race parents identify with and draw from their cultural backgrounds in raising and socializing their children. Miri Song presents a groundbreaking examination of how the meanings and practices surrounding multiracial identification are passed down through the generations. A revealing portrait of how multiracial identity is and is not transmitted to children, Multiracial Parents focuses on couples comprised of one White and one non-white minority, who were mostly “first generation mixed,” situating her findings in a trans-Atlantic framework. By drawing on detailed narratives about the parents’ children and family lives, this book explores what it means to be multiracial, and whether multiracial identity and status will matter for multiracial people’s children. Many couples suggested that their very existence (and their children’s) is a step toward breaking down boundaries about the meaning of race and that the idea of a mixed-race population is increasingly becoming normalized, despite existing concerns about racism and racial bias within and beyond various communities. A critical perspective on contemporary multiracial families, Multiracial Parents raises fundamental questions about the future significance of racial boundaries and identities.
The Role of Secure Attachment in Predicting Spiritual Maturity of Students at a Conservative Seminary

Previous research on attachment relationships suggests that early parental interactions generate internalized models of self and others–-models which are carried forward in later relationships. In order to investigate the relationships between secure attachment styles and their collective influence on spiritual maturity, a survey of 216 seminary students was conducted using the Parental Bonding Instrument, Adult Attachment Scale, and the Faith Maturity Index. Secure adult attachment styles were predicted to relate positively with spiritual maturity. Findings of the study suggest that adult measures of secure attachment styles are correlated with faith maturity. Measures of parental bonding evidenced minimal associations with adult attachment styles and were weaker correlates of faith maturity. Secure adult attachment was a stronger predictor of faith maturity when compared to measures of parental bonding. Implications are offered for religious training institutions, the church, and the community.
THE INFLUENCE OF MALE ADOLESCENT REBELLION ON ACADEMIC PERFORMANCE IN PUBLIC SECONDARY SCHOOLS

Purpose : The purpose of this study was to determine influence of male adolescent rebellion on academic performance in public secondary schools in Kiambu district. Methodology : The study used ex-post facto research design. Stratified sampling was used to select the participants in the study. Schools were stratified into single sex and co-education schools. Systematic sampling using the class lists was used to identify the students who constituted the sample. The research instruments were the students’ questionnaire, the deputy principal’s and the teacher counsellor’s interview guide. The sample constituted 240 male students, six deputy principles and six teacher counselors. A pilot study was done to pre-test the research instruments so as to estimate their reliability and validity. Data collected was analyzed using Statistical Package for Social Sciences (SPSS). The findings were presented using descriptive and inferential statistics.

Cost Management Practices in India: An Empirical Study

The present study of 53 CFOs of corporate India captures the development in the cost management practices such as accounting for overheads, applications of budgetary control and standard costing. It addition to traditional cost management techniques it also deals with applications of contemporary management tools such as activity-based costing. The hypotheses in general deal with the difference in the practices across sectors, stages, and level of adoption of contemporary cost management techniques. The firms are successful in capturing accurate cost and profit information from their ABC cost systems for value chain and supply chain analysis. The results suggest that the firms have better insight for benchmarking and budgeting with ABC cost system yet the consistency in their priority of budget goals is lacking unlike the firms who are using traditional costing systems. However both the ABC and traditional cost system users have clarity of reasons for effective implementations of planning and budgeting process in their organizations. There is no significant difference in the application of standard costing between the ABC-users and the traditional costing system users. This implies that the use of activity-based cost systems and standard costing is not mutually exclusive. There is a widespread use of sales variances and material variances vis-a-vis labor and overheads cost variances.
Fissure sealants: Knowledge and practice of Yemeni dental practitioners

Objectives This study was conducted to evaluate Yemeni dental practitioners' knowledge and practices concerning fissure sealants. Materials and Methods: A modified questionnaire consisted of 25-items was distributed to 500 dentists working in Sana'a City. Descriptive statistics and Chi-square/Fisher's exact tests were used for statistical analyses. Results: The response rate was 74%. Most of the respondents were male (61.3%), general practitioners (84.2%), and had <5 years of clinical experience (48.3%). The respondents showed a reasonable level of knowledge about sealants, with the majority (88%) believed that there is strong scientific evidence about fissure sealants effectiveness and around 90% showed a good understanding of sealant placement instructions. On the other hand, respondents showed insufficient knowledge about sealants clinical practice. Conclusion: Although a high proportion of dental practitioners showed adequate knowledge about dental sealant, following guidelines and standardized procedures in clinical practice is lacking. These emphasize the need for regular continuing education courses for dental professional.
Moving Boundary Models for Dynamic Simulations of Two-Phase Flows

Two-phase flows are commonly found in components in energy systems such as evaporators and boilers. The performance of these components depends among oth- ers on the controller. Transient models describing the evaporation process are important tools for determin- ing control parameters, and fast low order models are needed for this purpose. This article describes a gen- eral moving boundary (MB) model for modeling of two-phase flows. The new model is numerically fast compared to dis- cretized models and very robust to sudden changes in the boundary conditions. The model is a 7 th order model (7 state variables), which is a suitable order for control design. The model is also well suited for open loop simulations for systems design and optimization. It is shown that the average void fraction has a signifi- cant influence on the system response. A new method to calculate the average void fraction including the in- fluence of the slip ratio is given. The average void fraction is calculated as a symbolic solution to the in- tegral of the liquid fraction profile.
Rigorous analysis of software countermeasures against cache attacks

CPU caches introduce variations into the execution time of programs that can be exploited by adversaries to recover private information about users or cryptographic keys. Establishing the security of countermeasures against this threat often requires intricate reasoning about the interactions of program code, memory layout, and hardware architecture and has so far only been done for restricted cases. In this paper we devise novel techniques that provide support for bit-level and arithmetic reasoning about memory accesses in the presence of dynamic memory allocation. These techniques enable us to perform the first rigorous analysis of widely deployed software countermeasures against cache attacks on modular exponentiation, based on executable code.
How are drug regimen changes during hospitalisation handled after discharge: a cohort study

Objectives To investigate drug regimen changes during hospitalisation and explore how these changes are handled after patients are transferred back into the care of their general practitioners (GPs). Design Cohort study. Setting Patients in this multicentre study had undergone at least one change in their drug regimens at discharge from the general medicine departments at six hospitals in Norway. These changes were altered doses, discontinuation of drugs or start of new drugs. Clinical pharmacists visited the patients’ GPs 4–5 months after patient discharge and recorded any additional drug regimen changes. Results In total, 105 patients (mean age 76.1 years, 54.3% women) completed the study. On average, they used 5.6 drugs at admission (range 0–16) and 7.6 drugs at discharge (range 1–17). On average, 4.4 drug changes per patient (SD 2.7, range 1–16) were made at the hospital, and 3.4 drug changes per patient (SD 2.9, range 0–14) within 4–5 months of discharge. Of the 465 drug changes made in hospital, 153 were changed again after discharge (mean 1.5 per patient, SD 1.8, range 0–13). The drug regimens of 90 of these 105 patients were changed after discharge. The OR for extensive drug changes after discharge (≥ 4 changes) increased significantly with the number of drugs used at discharge from hospital (OR=1.29, 95% CI 1.04 to 1.59). Only 68 of 105 discharge notes contained complete drug lists, and only 24 of the discharge notes were received by the GPs within 7 days. Conclusions In addition to the extensive changes in drug regimens during hospitalisation, almost equally extensive changes were made in the initial months after discharge. Surveillance of drug regimens is particularly necessary in the period immediately after hospital discharge.

4-1BB Ligand-Mediated Costimulation of Human T Cells Induces CD4 and CD8 T Cell Expansion, Cytokine Production, and the Development of Cytolytic Effector Function1

4-1BB (CD137) is a costimulatory member of the TNFR family expressed on activated T cells. Its ligand, 4-1BBL, is expressed on activated APC. In the mouse, CD8 T cells are preferentially activated by agonistic anti-murine 4-1BB Abs. However, murine 4-1BBL can stimulate both CD4 and CD8 T cells. To date, there are only limited data on the effects of 4-1BBL on human T cell responses. To further understand the role of 4-1BBL in human T cell responses, we compared human CD4 and CD8 T cell responses to transfected human 4-1BBL plus TCR-mediated stimulation. Both human CD4 and CD8 T cells responded to 4-1BBL. The presence of 4-1BBL on the APC led to increased expansion, cytokine production, and the development of cytolytic effector function by human T cells. In unfractionated T cell cultures, CD4 and CD8 T cells could expand to a similar extent in response to signals through the TCR and 4-1BB, as measured by CFSE labeling and by quantitating T cell numbers in the cultures. In contrast to the results with total T cells, isolated CD8 T cells produced less IL-2 and expanded to a lesser extent than isolated CD4 T cells responding to 4-1BBL. Thus, 4-1BBL is most effective when both CD4 and CD8 T cells are included in the cultures. CD28 and 4-1BB were found to synergize in the induction of IL-2 by human T cells, and CTLA-Ig partially blocked 4-1BBL-dependent IL-2 production. However, a portion of the 4-1BBL-mediated effects were independent of CD28-B7 interaction.
Moduli spaces of hyperkähler manifolds and mirror symmetry

These lectures treat some of the basic features of moduli spaces of hyperkähler manifolds and in particular of K3 surfaces. The relation between the classical moduli spaces and the moduli spaces of conformal field theories is explained from a purely mathematical point of view. Recent results on hyperkähler manifolds are interpreted in this context. The second goal is to give a detailed account of mirror symmetry of K3 surfaces. The general principle, due to Aspinwall and Morrison, and various special cases (e.g. mirror symmetry for lattice polarized or elliptic K3 surfaces) are discussed.
Analyzing the Achievement and Isolation of Immigrant and U.S.-Born Students: Insights From PISA 2012

The 2016 Presidential election and the first months of the Trump administration have propelled immigration to the center of U.S. political debates. We use data from the Programme for International Student Assessment (PISA) 2012 to provide insights into the school experiences of high school–age immigrants and their U.S.-born peers. Our findings indicate that the immigrant–U.S.-born achievement gap is a race and wealth gap, and is also mediated by school factors. We also found that a substantial number of U.S.-born students attended schools that did not enroll immigrant students. We conclude by highlighting the research and policy implications of our findings.

The contradictory condition of ‘homelessness’ in the life of the transnational professional*

ABSTRACT This paper explores the condition of ‘homelessness’ as self-represented by a particular category of skilled professionals, who in the pursuit of work have relocated internationally more than once. The argument proposed is that, as a result of their highly mobile lifestyle, these transnational professionals experience ambiguous feelings regarding their notion of home, considered as a source of direction and stability associated with a given place or culture. Drawing on 48 personal narratives, this paper examines how the notion of home is manifested as part of the life of the transnational professional. The analysis follows the approach of intertextuality to identify associations with certain archetypal tales and novels associated with individual displacement. The findings show contradictory references to a sense of homelessness, which in the context of work is perceived as an ideal attitude, whereas in the private sphere generates negative feelings of self-alienation.
Evaluating the Employment Impact of a Mandatory Job Search Assistance Program

This paper is an evaluation of the British labor market program the "New Deal for the Young Unemployed" using administrative panel data on individuals between 1982 and 1999. This mandatory program involves extensive job assistance followed by various other options, including wage subsidies. We exploit the differential timing of the introduction of the program across regions as well as age-related eligibility rules to identify the program effect. Estimates of the employment effects of the mandatory job search assistance part of the program are presented using a variety of estimation techniques exploring combined "difference in differences" and matching procedures. Our key finding is that unemployed men are now 20% more likely to gain jobs than prior to the New Deal.
Retinal nerve fibre layer assessment in myopic glaucomatous eyes: comparison of GDx variable corneal compensation with GDx enhanced corneal compensation

Aim: To compare the results of scanning laser polarimetry (GDx) with variable corneal compensation (VCC) and enhanced corneal compensation (ECC) when applied to myopic glaucomatous eyes. Methods: Forty glaucoma eyes with moderate myopia (between −3 and −6 D) and 35 glaucoma eyes with high myopia (−8 D or greater) were enrolled in this study. GDx VCC, GDx ECC and standard automated perimetry (SAP) were performed. The prevalence of an atypical retardation pattern (ARP), the typical scan score (TSS) and retinal nerve fibre layer (RNFL) thickness were compared between VCC and ECC in both groups of myopic subjects. A correlation analysis between RNFL thickness and visual sensitivity was also conducted. Results: In both myopic groups, the mean TSS is significantly lower (p<0.0001), and the prevalence of ARP was significantly higher (p<0.0001) by VCC scans than by ECC scans. Temporal, superior, nasal, inferior, temporal (TSNIT) average and temporal average thickness showed significantly higher values (p<0.001) by VCC than by ECC. A statistically significant association was observed between TSNIT average and mean deviation of SAP by ECC scan. Conclusions: ECC scans showed a better retardation pattern and structure–function relationship than did VCC, and ECC appeared to be more suitable for RNFL assessment in glaucomatous eyes that are moderately to highly myopic.
Towards extensible automatic image annotation with the bag-of-words approach

Visual-word-based image categorization has proven to be very effective in several publications and contests. Recently, various approaches have been proposed to address the need for scalability and computational performance of classification based on Bag of Words. Despite these efforts, extensibility still remains an issue. Classifiers and histograms of visual words are both heavily dependent on an immutable general visual vocabulary created during the training step based on training images. Adding a new category that is insufficiently represented by the visual words in the vocabulary requires recreation of the visual vocabulary, complete recomputation of histograms and retraining of classifiers. When adding a new category, current approaches need to fully rebuild the whole recognition system. We address the problem of extensibility by combining class-specific vocabularies with outlier visual words. Classification is achieved by computing a scoring function for each class-specific vocabulary and selecting the highest score value. We show first results of our highly parallelizable and distributable approach on the Caltech 256 dataset.
A cognitive constraint model of dual-task trade-offs in a highly dynamic driving task

The paper describes an approach to modeling the strategic variations in performing secondary tasks while driving. In contrast to previous efforts that are based on simulation of a cognitive architecture interacting with a task environment, we take an approach that develops a cognitive constraint model of the interaction between the driver and the task environment in order to make inferences about dual-task performance. Analyses of driving performance data reveal that a set of simple equations can be used to accurately model changes in the lateral position of the vehicle within the lane. The model quantifies how the vehicle's deviation from lane center increases during periods of inattention, and how the vehicle returns to lane center during periods of active steering. We demonstrate the benefits of the approach by modeling the dialing of a cellular phone while driving, where drivers balance the speed in performing the dial task with accuracy (or safety) in keeping the vehicle centered in the roadway. In particular, we show how understanding, rather than simulating, the constraints imposed by the task environment can help to explain the costs and benefits of a range of strategies for interleaving dialing and steering. We show how particular strategies are sensitive to a combination of internal constraints (including switch costs) and the trade-off between the amount of time allocated to secondary task and the risk of extreme lane deviation.
