This study aims to explore the effect of an affective variable 'science anxiety' on students' achievement in science subject. By affective we refer to the learners' affect such as emotions, feelings, moods and attitudes involved in teaching-learning process. The chosen sample comprised of 1134 students (532 boys and 602 girls) of class X from 34 schools of Aizawl district of Mizoram. An adapted version of 'Science Anxiety Questionnaire' was used with some indigenous modifications to assess the level of science anxiety amongst the sample. The science anxiety scores of students were correlated with their science achievement scores obtained in class X board examination. Past researches have recognized 'science anxiety' as a negative affect responsible for student's underperformance in science. However, in the present finding the correlation coefficient value was found to be 0.1 indicating a very low but statistically significant positive relationship. This suggested that a minimum threshold level of science anxiety positively becomes the achievement in science. Anxiety levels were found to differ significantly between high and low science achievers, interestingly the high achievers (upper 27%) were found to be more science anxious suggesting that the very low positive relationship between the science anxiety and science achievement of students was contributed more from the high achievers. The findings revealed a significant difference between science anxiety levels of boys and girls, the latter being more science anxious. The chi-square analysis also supported that science anxiety is not independent of gender. KEYWORDS: Achievement in Science, Affect and Science, Science Anxiety, Secondary School Students

Abstract Diagnosis of Tomato spotted wilt virus (TSWV) in peanut can be accomplished by enzyme-linked immunosorbent assay (ELISA) or reverse transcription polymerase chain reaction (RT-PCR) but there has been no report of a direct comparison of the success of the two assays in evaluating infection rates of field-grown peanut. We collected peanut root samples from field-grown plants, 76 in 2006 and 48 in 2007, and tested these samples by both ELISA and RT-PCR assays for the presence of TSWV. Out of 124 samples, 50 (40.3%) and 57 (46.0%) were positive for TSWV by ELISA and RT-PCR respectively. In 13.7% of these samples, ELISA and RT-PCR differed in their results. However, Chi square analysis showed no significant difference between the results for these two assays. This result supports the conclusion that ELISA and RT-PCR are comparable for detecting TSWV infection rates in field-grown peanuts.

Domestic environmental pollution resulting from urban livestock farming was investigated in Makurdi using parasitological techniques. The test tube flotation technique was used for the parasitological analysis of animal faecal matter and soil samples collected from residential premises. Ectoparasitic fauna of dogs, goats, sheep and cattle cohabiting with humans within the same residential compound were also collected and identified. The hand-picking and body brushing methods were employed to search for ticks, fleas, lice and mites. Of the 150 soil samples examined, 55 (36.7 %) were positive for 1 or more eggs of helminth parasites. There was no significant difference in the distribution of eggs in the soil samples from the 3 areas sampled (c2=0.046, df=2, P>0.05). Ascaris species were the dominant parasite eggs found. Of the 180 faecal samples examined, 107 (59.4 %) were positive for 1 or more eggs of helminth parasites. Chi-square analysis showed no significant difference in the level of infection of different animal faeces sampled (c2=5.74, df=4, P>0.05). Ascaris species were again the dominating helminth parasite eggs found. There was also no significant difference in the prevalence of helminth eggs in the animal faecal samples from the 3 areas sampled (c2=5.99, df=4, P>0.05). A total of 1908 ectoparasites was recovered (ticks: 32.80 %; lice: 22.43 %; fleas: 22.06% and mite: 22.69 %). There was no significant difference in infestation animals between sexes (c2=0.10, df=4, P>0.05). The predominant genus encountered for ticks were Amblyomma, while Linognathus (43.90%), Ctenocephalides (97.38%) and Sarcoptes (58.89 %) were most predominant for lice, fleas and mites respectively. The public health implications of the findings, especially as these relate to the increasing incidence and prevalence of zoonotic infections, are discussed.

Sarotherodon Melanotheron

Over-population and stunted growth had been major challenges in the culture of tilapia. The use of synthetic androgen 17- α Methyl Testosterone (MT) was a breakthrough. However, its optimum level towards effective masculinization and growth is a concern. The aim of this research was to ascertain the optimum level of MT towards effective all-male population production and growth of Black-Chinned tilapia. In the present study, the effect of different dose rates of synthetic androgen 17-α Methyl Testosterone (MT) i.e., 0, 30, 60, and 120 mg of the hormone per kg of feed on sex, growth, and condition of Black-Chinned tilapia was evaluated. MT was administered orally by using powdered dry starter feed (Crude Protein 40 %) and Ethanol. The fry was fed for 30 days in the experimental tanks. At the end of the experiment, the sex ratios were determined by examining the operculum coloration as a means of sex identification. Growth performance was monitored by measuring and recording the morphometric characteristics. Bodyweight and total length of the fish on the start of feeding, end of feeding (one month sex reversal period), and two months after feeding were measured. The results of the present study showed that all MT receiving treatment showed a significantly higher male proportion than the control (0 mg MT/kg feed individuals). In all MT treatments groups, the control expects the 30 mg MT/kg in feed individuals’ deviate significantly from the normal 1:1 sex ratio (Chi-square analysis). The dose rate of 120 mg MT /kg feed resulted in the maximum male population (92.7%). Hence, for an effective high percentage of all-male population production in Black-Chinned tilapia, 120 mg MT /kg in feed is recommended. In terms of growth and condition factor, all the individual treatments, as well as the control, showed no significant difference. All the treated individuals showed similar condition factors during the pre and post-treatment, however, the individuals treated with 30 mg MT /kg feed exhibited better condition during the pre-treatment than the post-treatment period. Temperature, pH and dissolved oxygen recorded in this study were within the desirable limit for tilapia.

The aim of this study is to examine the reading anxiety levels of secondary school students according to parameters of gender, grade level, socioeconomic level and reading frequency. The total number of participants of the study is 598 who are students in a secondary school from different grade levels. In this study, reading anxiety scale and personal information form is used. The collected data is analyzed by using independent t-test, one-way analysis of variance and Pearson Product-Moment Correlation Coefficient. Just as the first result of the study, it has been found that the reading anxiety levels of secondary school students are low. No significant difference has been found between the levels of students’ reading anxiety and the levels of gender and grade. However, the students’ reading anxiety levels has differed significantly in favor of those with high socioeconomic level. According to the latest finding obtained from the study, the reading anxiety levels of the students has differed significantly in favor of those who have low reading frequency. Therefore, students reading less have more reading anxiety. These results obtained from the study are discussed as stated to the literature.

<p>The aim of this study is to examine whether reading habits have any effects on the academic achievement of the biology course of high school students in Turkey. In the research, the relational screening model was preferred from the quantitative research models and the phenomenological approach was preferred from the qualitative research models, so the mixed method was used. The study group consists of 266 students studying in the final year of various high schools and who took biology courses before in the province of Kars in Turkey. Data were collected by the questionnaire form prepared by the researchers. In the questionnaire, the participants were asked 12 questions in total; 4 questions to determine the variables of the type of school, education fields, gender, school report marks, 5 close-ended questions to be thought to be able to determine their reading habits, 2 open-ended questions and 1 metaphor question. Frequency and percentage values were calculated for descriptive analysis of the answers given to the questionnaire items. Chi-square analysis was used to examine the relationship between demographic characteristics and the reading habits of the students, and the content analysis technique was used to analyze metaphors. </p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0882/a.php" alt="Hit counter" /></p>

ABSTRACT Background  In 2013, milestone ratings became a reporting requirement for emergency medicine (EM) residency programs. Programs rate each resident in the fall and spring on 23 milestone subcompetencies. Objective  This study examined the incidence of straight line scoring (SLS) for EM Milestone ratings, defined as a resident being assessed the same score across the milestone subcompetencies. Methods  This descriptive analysis measured the frequencies of SLS for all Accreditation Council for Graduate Medical Education (ACGME)–accredited EM programs during the 2015–2016 academic year. Outcomes were the frequency of SLS in the fall and spring milestone assessments, changes in the number of SLS reports, and reporting trends. Chi-square analysis compared nominal variables. Results  There were 6257 residents in the fall and 6588 in the spring. Milestone scores were reported for 6173 EM residents in the fall (99% of 6257) and spring (94% of 6588). In the fall, 93% (5753 residents) did not receive SLS ratings and 420 (7%) did, with no significant difference compared with the spring (5776 [94%] versus 397 [6%]). Subgroup analysis showed higher SLS results for residents' first ratings (183 of 2136 versus 237 of 4220, P &lt; .0001) and for their final ratings (200 of 2019 versus 197 of 4354, P &lt; .0001). Twenty percent of programs submitted 10% or more SLS ratings, and a small percentage submitted more than 50% of ratings as SLS. Conclusions  Most programs did not submit SLS ratings. Because of the statistical improbability of SLS, any SLS ratings reduce the validity assertions of the milestone assessments.

Objectives: The radiographic crossover sign (COS) is an indicator of acetabular retroversion, classically representing anterosuperior overcoverage often treated with acetabuloplasty which could exacerbate acetabular hypovolemia in dysplasia. No prior study has investigated the prevalence of acetabular retroversion in patients with dysplasia undergoing hip arthroscopy, acetabuloplasty rates, and outcomes in this setting. Study objectives are to report the prevalence of acetabular retroversion in dysplasia, the influence of the COS on arthroscopic acetabuloplasty rates, and relative outcomes compared with control groups. Methods: A retrospective cohort study was performed from a prospectively collected multi-center database. Patients undergoing isolated hip arthroscopic surgery were assigned to dysplasia (lateral center-edge angle (LCEA) ≤ 25°) or one of two control groups: normal(LCEA 26-38°), or pincer femoroacetabular impingement (FAI)(LCEA ≥ 39°). The prevalence of COS and acetabuloplasty rates between and within study and control groups were compared (Chi square analysis). Minimum 2 year outcomes utilizing iHOT-12 were compared (analysis of variance). Results: Of 401 study patients, 64 (16%) comprised the dysplasia group, 273 (68%) normal group, and 64 (16%) pincer group. Mean LCEAs were 22.3°, 31.5°, and 42.4°, respectively (p<0.001). COS prevalence was similar between groups at 31%, 26%, and 33%, respectively (p=0.873). Acetabuloplasty rates were dependent on the amount of acetabular coverage with lowered rate in the dysplasia group(40%) and increasing rates in the normal(52%) and the pincer(90%) groups (p=0.013). Post-operative iHOT-12 scores improved in all groups (68, 74, and 77, respectively, p=0.222). Patients with a COS plus rendered acetabuloplasty reported similar scores that improved to 77, 74, and 79, respectively,(p=0.949). Patients with dysplasia with COS averaged 73.1(SD 23.3) iHOT-12 score compared to 67.1(SD: 28.7) for the patients with dysplasia without COS (p=0.466). Within the dysplasia with COS subgroup, there was no significant difference in iHOT-12 scores between the group with acetabuloplasty (77.0;SD:17.1) and without acetabuloplasty (70.4;SD:27.4,p=0.580). Conclusion: Acetabular retroversion occurs with similar prevalence in borderline dysplasia compared with non-dysplastic hips undergoing hip arthroscopy but with lower acetabuloplasty rates not influenced by the COS. Arthroscopic outcomes of dysplasia with retroversion are similarly successful and comparable with those of dysplasia and non-dysplastic hips. Although infrequently performed, acetabuloplasty did not compromise outcomes in dysplasia with retroversion.

62 Background: Esophageal cancer management has evolved due to improvements in staging and treatment strategies. Endoscopic local excision presents an attractive option for definitive management of T1 cancers, avoiding the morbidity of esophagectomy. We hypothesized that for cT1N0 cancers, patients who underwent local excision would have lower survival compared to esophagectomy due to potential discordant staging. Methods: The National Cancer Database was queried for esophageal squamous cell carcinoma (SCC) and adenocarcinoma (AC) with AJCC T1N0 clinical stage who underwent local excision (n = 1625) or esophagectomy (n = 3255) between 1998 and 2012. Chi-square analysis was used to compare demographic and clinical characteristics by procedure. Chi-square trend analysis was performed to assess trends in procedure type over time. Cox Regression analysis was performed to assess survival by procedure controlling for demographic and clinical characteristics. Results: Between 1998 and 2012, the proportion of patients who underwent local excision increased from 12% to 50% for all patients (p < 0.001); from 17% to 40% for SCC patients (p < 0.001); and from 9% to 51% for AC patients (p < 0.001). Surgical procedure varied significantly by demographic, socioeconomic status, facility, and tumor-related factors. 65% of cT1N0 cancers had concordant clinical and pathological staging after esophagectomy, with 11% having positive nodal disease; 44% were concordant after local excision. While no significant difference was seen in unadjusted survival, adjusted Cox Regression analysis indicated worse survival after esophagectomy compared to local excision for all cases (HR 1.67; 95% CI, 1.40-2.00) and for ACs with concordant staging (HR 1.54; 95% CI, 1.11-2.14). Conclusions: Local excision for cT1N0 esophageal cancer has increased over time. Staging concordance for esophagectomy is seen in two-thirds of cases. Contrary to our hypothesis, patients undergoing local excision for T1N0 cancers have better overall survival than those undergoing esophagectomy, which may reflect early differences in mortality and/or selection bias. As this study was unable to distinguish T1a from T1b, further analysis is warranted.

AbstractThe Centers for Medicare and Medicaid Services has implemented the Value-Based Purchasing (VBP) score as a pay-for-performance reimbursement model. Patient experience, as measured by the Press Ganey (PG) survey, currently comprises 20% of total VBP score. It is therefore beneficial for the orthopaedist to become familiar with these changes to maximize profits. Currently, a paucity of data exists that elucidates which factors influence PG scores between men and women following total knee arthroplasty (TKA). Therefore, we asked: (1) which PG survey factors most influences hospital ratings among men and women patients post-TKA and (2) is there a significant difference in overall hospital ratings among men and women cohorts post-TKA? We queried the PG database for patients who received a TKA between November 2009 and January 2015, yielding 224 men (mean age 64 years, range: 39–88) and 519 women (mean age 65 years; range, 25–92). A multiple regression analysis was performed for each cohort with overall hospital satisfaction as the dependent variable to assess the influence (β-weight) each PG domain imparted on overall hospital rating. A chi-square analysis and t-test were performed to assess categorical and continuous variables, respectively. For men, communication with nurses (β = 0.408, p = 0.016), followed by communication about medications (β = 0.261, p = 0.032), most influenced overall hospital rating. For women, communication with nurses (β = 0.479, p < 0.001) most influenced overall hospital rating. This was followed by staff responsiveness (β = 0.201, p = 0.046), pain management (β = 0.263, p = 0.015), and communication about medications (β = − 0.152, p = 0.029). It is of great advantage for the orthopaedist to focus on the PG domains most pertinent to each patient gender post-TKA. For both genders, overall hospital rating was significantly influenced by communication with nurses and information about medication. However, staff responsiveness and pain control were of significant importance in determining overall hospital rating for women. Therefore, orthopaedists should consider focusing on these factors depending on the gender of the patient to optimize satisfaction.
