Sentiment Analysis using an ensemble of Feature Selection Algorithms

To determine the opinion of any person experiencing any services or buying any product, the usage of Sentiment Analysis, a continuous research in the field of text mining, is a common practice. It is a process of using computation to identify and categorize opinions expressed in a piece of text. Individuals post their opinion via reviews, tweets, comments or discussions which is our unstructured information. Sentiment analysis gives a general conclusion of audits which benefit clients, individuals or organizations for decision making. The primary point of this paper is to perform an ensemble approach on feature reduction methods identified with natural language processing and performing the analysis based on the results. An ensemble approach is a process of combining two or more methodologies. The feature reduction methods used are Principal Component Analysis (PCA) for feature extraction and Pearson Chi squared statistical test for feature selection. The fundamental commitment of this paper is to experiment whether combined use of cautious feature determination and existing classification methodologies can yield better accuracy

Genetic Effects on Aggregation Behavior of Beetles

Aggregations of insects can often cause problems because they consume large amounts of resources. Species like the Red Flour Beetle are particularly damaging because they can invade locations where humans store food (Lles 2018). Interestingly, different genetic strains of the Red Flour Beetle produce different amounts of aggregation pheromone (Gerken, Scully, Campbell 2018). Here, we tested if two different genetic strains of Red Flour Beetle formed aggregates based on their genetic background or their recent living environments. We found that beetles aggregated based on genetic factors, with environmental conditions being relatively weak. These data suggest that understanding the genetic background of pest insects can shed light on their behavior

Apparatus for determining changes in limb volume

Measuring apparatus for determining changes in the volume of limbs or other boty extremities by determining the cross-sectional area of such limbs many comprise a transmitter including first and second transducers for positioning on the surface of the limb at a predetermined distance there between, and a receiver including a receiver crystal for positioning on the surface of the limb. The distance between the receiver crystal and the first and second transducers are represented by respective first and second chords of the cross-section of the limb and the predetermined distance between the first and second transducers is represented by a third chord of the limb cross section

Information and voting power in the proxy process

We document shareholder support for wealth-decreasing changes in corporate governance in the form of antitakeover charter amendments. the enactment of these amendments is shown to be related to ownership structure. This gives rise to a sample selection bias that contaminates traditional event-study results and explains the discrepancy between our findings and those reported in previous studies. We also provide evidence that strategic behavior by managers plays a role in the adoption of these amendments.Stockholders ; Consolidation and merger of corporations

Oral Hygiene (OHI-S) and DMFT Status among Type 1 Diabetic Adolescents Aged 12-19 Years: A Case-Control Study

INTRODUCTION: Diabetes in any form (type 1 or type 2) has the potential to affect the oral health of an individual. AIM: To assess the oral hygiene status (simplified) and DMFT among adolescents aged 12-19 years with type 1 diabetes (cases) in Jammu District, Jammu and Kashmir (J&K), India MATERIALS AND METHOD: A total of 50 patients aged 12-19 years with type 1 diabetes mellitus, screened via medical history from  August 2017 to August 2018 were enrolled in the study. The control group consisted of 51 healthy adolescents matched for age and gender selected randomly. The DMFT index was used to record the Decayed, Missing, Filled teeth, while the OHI-S Index was used to assess the Oral Hygiene Status. The examinations were done under artificial light and  data was analyzed using SPSS version  19.0. The t-test, Odd’s Ratio (OR) and multiple regression were used to analyze the data.  RESULTS: Of a total of 101 participants(50 cases and 51 controls) enrolled in the study, cases reported higher values of OHI-S and DMFT  as compared to controls. The cases had an OHI-S score of 3.12±3.2 indicating poor oral hygiene, the controls’ score of 2.54±1.1 revealed fair oral hygiene and no significant statistical differences were found (OR=2.1). A significant difference (p=0.03) was seen upon comparison of DMFT among cases (4.67±6.6) and controls (3.82±2.9). The cases were 1.7 (OR) times more likely to have higher DMF values as compared to controls CONCLUSION: Efforts must be reinforced among adolescents emphasizing the importance of oral health, through more frequent dental education camps in Jammu district, J&K, Indi

Observed Risk Factors and the Prevalence of Potential Oral Malignant Lesions among a North Indian Population

INTRODUCTION: The menace of oral cancer has become a public health concern and its prevalence is increasing with every passing day, making it the sixth most common cancer across the globe. OBJECTIVE: To evaluate the prevalence and risk factors for potential oral malignant disorders in a middle aged north Indian population.MATERIALS AND METHODS: Adopting a Cross-sectional study design, this study examined a total of 944 participants in the Delhi-NCR region and males formed a majority of the population (569, 60.3%). Data was collected using a pre-tested and pre-validated questionnaire. Descriptive statistics was applied and the chi-squared test (for qualitative data) and independent samples t-test(for quantitative data) was applied to find out statistical differences (Using SPSS 21.0), if any.RESULTS: It was reported that 201 (21.29%) of the study population suffered from oral malignant lesions, and the most prevalent lesion was OSMF [115, 12.18%] followed by leukoplakia [49, 5.19%]. The prevalence of oral malignant lesions among males was found to be higher(18.97%) as compared to females. A significant difference was found between the oral lesions and tobacco ever and never chewers (p<0.001). CONCLUSION: The results indicate a need to focus tobacco cessation programmes in the population of Delhi-NCR and reinforce it from time to time to reduce the burden of such Oral Malignant Disorders
