I describe an in-class activity designed to meet the needs of research methods students who frequently encounter survey research and multiple regression. Groups of students receive the common task of developing a small number of questionnaire items to predict a specified criterion. Students then receive descriptive statistics and multiple regression results demonstrating the ability of their items to predict the specified outcome. In a sample of 8 groups, reactions to the activity were highly positive. In addition, students who participated in the activity ( n = 30) scored slightly (although not statistically significant) higher on a subsequent exam than those in a control group ( n = 18).

Descriptive Survey

Abstract This work investigated the management of biodegradable waste among residents in a South-East Locality of Nigeria. The design adopted was descriptive survey design. The population size was 270,902 residents in Ahiazu Mbaise Local Government Area. The sample for the study consisted of 840 respondents selected using a multi-stage procedure. Four objectives guided the study. The data collected were analyzed using descriptive statistics of frequency tables and simple percentages. The study revealed that majority(706; 84&%) of the residents agreed on the common types of biodegradable waste generated; majority use broom and bare hand (hand picking) to collect biodegradable waste with the frequencies of 648 (77%) and 560 (67%)respectively; majority agreed on the methods of transporting biodegradable waste with an overall frequency of 584 (70%) and that majority agreed the methods of disposal of biodegradable waste with an overall frequency of 632 (75%). Based on these, it was recommended among others that health educators should be employed in the ministry of environment with mandate of organizing health talks for the residents to enlighten them on the management of biodegradable and that government should provide adequate means and facilities for the management of waste in our surroundings.

Motives of espionage against ones own country in the light of idiographic studies The money is perceived as the common denominator among people who have spied against their own country. This assumption is common sense and appears to be self-evident truth. But do we have any hard evidences to prove the validity of such a statement? What method could be applied to determine it? This article is a review of the motives behind one's resorting to spying activity which is a complex and multifarious process. I decided to present only the phenomenon of spying for another country. The studies on the motives behind taking up spying activity are idiographic in character. One of the basic methodological problems to be faced by the researchers of this problem is an inaccessibility of a control group.

The fascinating world of lichens draws the attention of the researchers because of the numerous properties of lichens used traditionally and, in modern times, as a raw material for medicines and in the perfumery industry, for food and spices, for fodder, as dyes, and for other various purposes all over the world. However, lichens being widespread symbiotic entities between fungi and photosynthetic partners may acquire toxic features due to either the fungi, algae, or cyano-procaryotes producing toxins. By this way, several common lichens acquire toxic features. In this survey, recent data about the ecology, phytogenetics, and biology of some lichens with respect to the associated toxin-producing cyanoprokaryotes in different habitats around the world are discussed. Special attention is paid to the common toxins, called microcystin and nodularin, produced mainly by the Nostoc species. The effective application of a series of modern research methods to approach the issue of lichen toxicity as contributed by the cyanophotobiont partner is emphasized.

Multiple organ dysfunction syndrome (MODS) is a key factor that leads to death in elderly patients with sepsis. Therefore, early prevention and treatment of gastrointestinal dysfunction (GIDF) in elderly patients with sepsis is an important measure to prevent MODS occurrence. This research explores the correlation between intestinal microflora and GIDF in elderly patients with sepsis and provides ideas for the prevention and treatment of GIDF in elderly patients with sepsis. In this study, 152 patients with sepsis (122 patients with sepsis and GIDF) treated in the Third Affiliated Hospital of Yunnan University of Chinese Medicine from January to September 2019 were selected as the sepsis group and 100 elderly who had normal physical examination results were selected as the control group. The common intestinal microflora of the two groups was compared. Patients with sepsis and GIDF were treated as the GIDF group and the other patients with sepsis were treated as the non-GIDF group. The common intestinal microflora, gastrointestinal indicators, serum inflammatory factors, and immune function indices were compared between the two groups. Correlation analysis of the observed indices with statistical significance was carried out. The results showed 152 patients with sepsis and 122 patients with sepsis and GIDF; thus, the incidence of sepsis with GIDF was 80.26%. The total average score of sepsis with GIDF was 3.61±0.09. There was no statistically significant difference in GIDF scores of patients ages 65–75 and > 75 years old. The number of Bifidobacterium and Lactobacillus in elderly patients with sepsis was lower and the number of Escherichia coli was higher than in the control group. In elderly patients with sepsis, the number of Bifidobacterium and Lactobacillus in the GIDF group was lower and the number of E. coli was higher than in the non-GIDF group. White blood cell (WBC) count, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), gastrin (GAS), and diamine oxidase (DAO) in GIDF patients were higher and motilin (MOT), CIT (CIT), CD4+, and CD8+ were lower than in the non-GIDF group. WBC count, PCT, CRP, TNF-α, GAS, and DAO were negatively correlated with the number of Bifidobacterium and Lactobacillus but positively correlated with E. coli. MOT, CIT, CD4+, and CD8+ were positively correlated with the number of Bifidobacterium and Lactobacillus but negatively correlated with E. coli. There was a negative correlation between Bifidobacterium and Lactobacillus and GIDF score and a positive correlation between E. coli and GIDF score. Therefore, the change in the intestinal microflora in elderly patients with sepsis is related to GIDF.

In survey research, vignette experiments typically employ short, systematically varied descriptions of situations or persons (called vignettes) to elicit the beliefs, attitudes, or behaviors of respondents with respect to the presented scenarios. Using a case study on the fair gender income gap in Austria, we discuss how different design elements can be used to increase a vignette experiment’s validity and reliability. With respect to the experimental design, the design elements considered include a confounded factorial design, a between-subjects factor, anchoring vignettes, and blocking by respondent strata and interviewers. The design elements for the sampling and survey design consist of stratification, covariate measurements, and the systematic assignment of vignette sets to respondents and interviewers. Moreover, the vignettes’ construct validity is empirically validated with respect to the real gender income gap in Austria. We demonstrate how a broad range of design elements can successfully increase a vignette study’s validity and reliability.

Objective: To determine whether hydrogen peroxide (H2O2) mouthwash influences the outcome of secondary post-tonsillectomy hemorrhage in children. Study Design: Ten-year retrospective study of all children with secondary post-tonsillectomy hemorrhage. Setting: Tertiary otolaryngology center. Results: Of the 156 patients, 59 received H2O2 and 97 did not. All patients received broad-spectrum intravenous antibiotics. The average rehospitalization duration due to hemorrhage was 1.7 days (H2O2 group) and 1.6 days (control group). In the H2O2 group, 8.5% required surgery, compared with 10.3% in the control group. Further hemorrhage episodes requiring readmission occurred in 3.4% of the H2O2 group and 3.1% of controls. There was no difference between the 2 groups in rehospitalization duration ( P = 0.49), rate of surgical intervention ( P = 0.85), and rate of readmission with further hemorrhage ( P = 0.92). Conclusion: Hydrogen peroxide mouthwash does not improve the outcome of secondary post-tonsillectomy hemorrhage in pediatric patients. Significance: This study does not support the common practice of treating post-tonsillectomy hemorrhage with H2O2.

And Behaviors

Learner autonomy has become the prevailing theme of language education for nearly four past decades, especially its three constructs such as responsibilities, abilities and behaviors. Thus, the current study embraced salient traits of a survey research design to scrutinize these constructs as appraised by the Vietnamese tertiary learners. The study recruited the participation of 80 English-majored students at Hung Vuong University, Vietnam. Their appraisal was elucidated by a quantitative instrument, that is, a 28-item questionnaire whose descriptive statistics were yielded by SPSS 22.0. The study found that a greater proportion of the informants ultimately recognized their autonomous responsibilities, acknowledged their autonomous abilities, and estimated some autonomous behaviors both inside and outside the classroom. Brief conclusion was made at the end of the paper.
