Abstract Objective – Academic librarians consistently offer individualized help to students and researchers. Few studies have empirically examined the impact of individualized research consultations (IRCs). For many librarians, IRCs are an integral part of their teaching repertoire. However, without any evidence of an IRC’s effectiveness or value, one might ask if it’s worth investing so much time and effort. Our study explored the impact of IRCs on students' search techniques and self-perceived confidence levels. We attempted to answer the following questions: 1) Do IRCs improve students’ information searching techniques, including the proper use of keywords and/or subject headings, the accurate use of Boolean operators, and the appropriate selection of specialized resources/databases? 2) Do IRCs influence students’ confidence level in performing effective search strategies? Methods – Our study used a mixed-methods approach. Our participants were students from the Faculties of Health Sciences and Medicine at the University of Ottawa, completing an undergraduate or graduate degree, and undertaking a research or thesis project. Participants were invited to complete two questionnaires, one before and one after meeting with a librarian. The questionnaires consisted of open-ended and multiple choice questions, which assessed students' search techniques, their self-perceived search techniques proficiency and their confidence level. A rubric was used to score students' open-ended questions, and self-reflective questions were coded and analyzed for content using the software QSR NVivo. Results – Twenty-nine completed pre and posttests were gathered from February to September 2016. After coding the answers using the rubric, two paired-samples t-tests were conducted. The first t-test shows that students’ ability to use appropriate keywords was approaching statistical significance. The second t-test showed a statistically significant increase in students’ ability to use appropriate search strings from the pretest to the posttest. We performed a last paired-samples t-test to measure students’ confidence level before and after the appointment, and a statistically significant increase in confidence level was found. Conclusion – Out of three paired t-tests performed, two showed a statistically significant difference from the pretest to the posttest, with one t-test approaching statistical significance. The analysis of our qualitative results also supports the statement that IRCs have a positive real impact on students’ search techniques and their confidence levels. Future research may explore specific techniques to improve search strategies across various disciplines, tips to improve confidence levels, and exploring the viewpoint of librarians.

The Impact

Background:Clinicians are encouraged to use non-pharmacologic interventions first as part of the treatment of responsive behaviours due to mental health conditions. Music therapy is an example of such an intervention. In recent years, there has been an increased research focus on individualized music (IM) because it considers patient’s personal music preferences. However, the findings of whether IM listening is more beneficial than general music listening has been inconsistent.Objective:This study is to further compare the effects of IM and elevator (baseline) music listening on enjoyment behaviours of geriatric inpatients.Methods:Fifteen participants were recruited from a geriatric psychiatry unit in an acute tertiary mental health facility in British Columbia, Canada. Their mean age was 74 years and their mean MMSE was 18. Each participant attended two 30-minute music listening sessions. Each session included a 15-minute baseline music playlist and a 15-minute IM playlist. The sequence of the two playlists was counterbalanced for each participant across the two sessions. The IM playlists were created by interviewing each participant with a personalized music preference questionnaire. The baseline (elevator) playlist was simply consisted of instrumental, non-lyrical jazz and classical music and was the same for every participant. The enjoyment behaviors during the sessions for each participant were measured by the Enjoyment Behavioral Coding Scheme (EBCS), which was developed for this project based on previous literature and was shown to have a good inter rater reliability.Results:The average total scores of the EBCS across two sessions of IM and baseline music listening were calculated for each participant. Paired samples t-test was used to compare the scores. Though the mean total score of the EBCS for IM session was higher than that for the baseline session, the t-test showed the difference did not reach statistical significance.Conclusion:Participants appeared to enjoy both the IM and baseline music sessions equally.

This research deals with the impact of intensity of inbound and outbound tourism on the sphere of passenger air carriages, based on the dataset that covers the indicators across different economic regions over the period of 2015-2017. The results based on building a correlation-regression model have shown that there is a close connection between tourism development and passenger carriages intensity. Verification of the model by the criteria of Fisher and Student (F-test and t-test) have proved the hypothesis about its statistical significance only after excluding five countries, for which no direct connection is observed between the chosen indictors. Further research has shown that the level of the country economic development does not influence the passenger air carriages industry. Specific attention is paid to the state and main tendencies of passenger air carriages industry in Ukraine. Impact of tourism on this kind of activity is analysed. The basic measures to increase its efficiency are highlighted.

This paper investigates the impact of demonetization process on the performance of Nifty 50 and its Sectorial Indices. The study uses data of closing prices from 28 June 2016 up to 20 March 2017. The study employs descriptive statistics, paired sample T test and ANOVA to evaluate the impact of demonetization process on the performance of Nifty 50 and its Sectorial Indices. It has found that there is statistical significance at the level of 5% that Nifty 50 dropped after the demonetization event as compared to the pre demonetization event. Further, the results reveal that most of Sectorial Indices of Nifty 50 sloped downward post demonetization event and the significance of the statistical results are varied from one sector to another. It is recommended that periodic review of the policy should be made to iron out the negative impacts of demonetization. Also, it is imperative to evaluate the impact of demonetization on the short, medium, and long run to avoid any grey areas for any future policy regarding cashless economy or demonetization.

Abstract PD-1 has a role in regulating the response of the immune system to the cells of the human body. Paris et al. reported that combination antiretroviral therapy did not change % CD4+ of PD-1highCTLA-4lowCD127high early/intermediated T cells of human immunodeficiency virus infected patients but increased the percent of the marker limited to initial CD4 counts <200 with Wilcoxon signed-rank test. We hypothesized that the treatment increased the marker value in patients whose initial marker value is less than a particular value and decreased the marker value in other patients and that the test misleadingly concluded that the treatment did not change the marker value. General subgroup analyses correctly estimate the statistical significance of such a reaction or difference between such reactions only when the reaction of both of subgroups or both difference between such subgroups is statistically significant. We propose Ishida’ t-test for paired samples that can correctly judge the probability without division of the group into subgroups, and Ishida’ t-test for unpaired samples that can correctly judge the statistical significance of the difference between such reactions. We also showed that many treatments cause such increase and decrease of marker values relating PD-1 of subjects.

BACKGROUND: E-learning is increasingly used during the COVID-19 pandemic, however the impact of this change on students is not known. This study aimed to evaluate perception and satisfaction of health sciences students towards E-learning during the COVID-19 lockdown. METHODS: A structured questionnaire was distributed to 2000 health care students either through email or social media platforms. The questionnaire was divided into two sections: the first section addressed demographic information such as age, education level, course of study, number of lectures attended and country. The second section gathered information on perception and satisfaction of students using 13 close-ended questions. Frequencies and percentages were assessed for demographic data, perception and satisfaction level of students. The paired sample t-test, independent t test and Spearman correlation were applied to evaluate statistical significance between different variables of the study. A p-value of <0.05 was considered significant. RESULTS: Data from 1255 participants were included at a response rate of 66.4%. More than one third (37%) of the students took 25 or more online E-learning sessions and 47% preferred Zoom as an online platform. Participants belonged to 11 countries from developed and developing nations. 41% reported interference of E-learning due to network problems. 60% considered that clinical and practical skills are best learned in clinics and laboratories. More than one third of the students preferred classroom teaching and 34% of the students did not feel confident enough to take exit exams after E-learning sessions. CONCLUSION: E-learning satisfaction levels were better among developed countries (7.34) compared to developing countries (5.82). The majority of participants agreed that E-learning was satisfactory in acquiring knowledge, however not effective in acquiring clinical and technical skills. As the COVID-19 lockdown eases, there is a need for improvement in the methods employed in E-learning and more blended learning among healthcare students is recommended.

This study aims to investigate the effectiveness of using visual materials in teaching vocabulary to deaf students of EFL. For this purpose, 80 deaf students from a state special education vocational high school in Turkey contributed to this study. All students had first English classes in their lives and they are at the starter level of English, thus pre-test for their English proficiency was not given. The students were randomly divided into two groups to form the experimental group and the control group. 10 vocabulary items per week were taught to the students, and 50 target vocabulary items in total were taught during the whole study. To the experimental group, the vocabulary items were taught via visual materials together with the sign language. The control group was not presented with any visual items during the teaching process of the experiment, only sign language instruction was used for them. After the treatment, a vocabulary test was given to each group as an immediate post-test to measure the impact on learning. Six weeks after the immediate tests, delayed post-test was given to the groups to test long term retention. The results of the two post-tests were analyzed through Independent Samples t-test and Paired Samples t-test calculations to investigate the effectiveness of visual materials. According to the results of the study, visual materials were found to be more effective than using only the sign language that does not contain any visual items in teaching vocabulary items to deaf learners who learn English as a foreign language.
