How to reduce the cost of competition in the industry, identify effective customers, and understand the emotional needs and consumer preferences of customers, so as to carry out fast and accurate commercial marketing, is an important research topic. In this paper, we discussed the method for the analysis of three product data which represent the customer-supplied ratings and reviews for microwave ovens, baby pacifiers, and hair dryers sold in the Amazon marketplace over the time period. The sentiment analysis, linear regression analysis, and descriptive statistics were implemented to analyze the three datasets. Based on the sentiment analysis given by the naive Bayesian classification algorithm, we found that the star rating is positively correlated with the reviews, while the helpfulness ratings have no specific relationship with the star rating and reviews. We use multiple regression analysis and clustering algorithm analysis to get the relationship between the 4 indexes such as time, star rating, reviews, and helpfulness rating. We find that there is a positive correlation between the 4 indexes, and the reputation of the product online market is improving as time grows. Based on the analysis of the positive reviews and star ratings, we suggested indicating a potentially successful or failing product by the positive reviews. We also discussed the relations between the star ratings and number of reviews. Finally, we selected the words from the Amazon sentiment dictionary as candidate words. By counting the candidate words’ appearance in the review, the keywords that can reflect the star rating were found.

e19402 Background: The term “Financial toxicity(FT)” is widely used to describe the distress or hardship patients suffering from the financial burden of cancer treatment[1]. Increased evidences have showed that cancer-associated FT is common and has a negative impact on patients’ mental health, quality and length of life[1,2]. The scale of COmprehensive Score for financial Toxicity-Functional Assessment of Chronic Illness Therapy (COST-FACIT) was used to assess the FT of cancer patients, which has been validated and widely used internationally [3] and China [4]. To our knowledge, little is known about the FT of breast cancer patients in China. The aim of this study is to assess the FT and to investigate patients and cancer characteristic that associated with it in patients in central China. Methods: This was a cross-sectional study among 188 patients with stage 0-III women breast cancer admitted in Bethune hospital in Taiyuan, Shanxi province during January - May 2019. FT was self-reported using the COST-FACIT. Patients’ socio-demographic factors, clinical examination, and cancer treatment were collected from questionnaire and hospital record. The financial concern and coping strategy was self-reported. Factors associated with FT was identified using linear regression analysis. Results: One hundred and sixty-six (88.2%) completed the questionnaire. The COST score ranged 0-40 with a mean of 21.2 (median 22.5, standard deviation 8.1). On multivariate linear regression analysis, older age (β coefficient: 0.19, 95% CI: 0.10-0.29, p<0.001), higher household income (β coefficient: 3000-5000 Yuan: 6.48, 95% CI: 2.78-10.17, p =0.001; ≥ 5000 Yuan: 11.17, 95% CI: 7.25-15.09, p<0.001) were positively associated with COST scores. Advanced cancer stage was the strongest predictor of FT among the cancer characteristics (β coefficient: -1.81, 95% CI: -3.17, -0.46, p=0.009). To cope with the FT, 131 (78.8%) patients decreased non-medical expenses, and 56 (33.7%) reduced or quit treatment. Conclusions: FT was significantly associated with patient’s age, income, and cancer stage. Women having financial concerns after diagnosis were more likely to reduce their non-medical expenses and even quit treatments. Clinicians should take into account the FT levels in all patients and work out appropriate treatment strategies for optimal clinical outcome.

The Cost

This study challenges the fairness of sectional title schemes’ levies that are ordered by the Sectional Title Act (95 of 1986) to be allocated according to the participation quota (floor area) of units. Studies have shown that larger units in a sectional title scheme tend to subsidise the levies of smaller units. A log-transformed linear regression analysis was performed to investigate the cost behaviour of 113 sectional title schemes. The results revealed that 86% of the variation in the operating costs of a scheme is attributable to the variation in the area of a scheme, while 87% of the variation in operating costs is attributable to a variation in the number of units in a scheme. The conclusion is that the area and the number of units in a scheme are equally significant drivers of operating costs. Therefore, the study recommended that the levies should be allocated on a 50/50 basis with regard to area and number of units.

Bisexual And Transgender

Some students perceive lesbian, gay, bisexual, and transgender (LGBT) positively, even though LGBT is a sexual deviation that is not appropriate with values and norms. There are several factors that influence an individual's perception of LGBT, including sexual identity. This study aims at looking at the contribution of sexual identity to student perceptions about LGBT. This research used a quantitative approach with a descriptive method and a simple linear regression analysis. The sample of this research was 385 taken from 15.752 undergraduate students of Universitas Negeri Padang which the sample was drawn by using the Slovin formula and continued with a Proportional Random Sampling technique. The instrument used was the Guttman model's sexual identity scale and the scale of students' perceptions of the LGBT Likert model. After analyzing the data with the descriptive technique and the simple linear regression analysis, the results showed that sexual identity significantly contributed to the students' perceptions of LGBT. This research has implications as a basis for counselors to help students avoid sexual identity mismatches and prevent the emergence of positive perceptions of LGBT.
