AbstractThis investigation was concerned with fauna above and within the litter, fermentation, and humus layers of the soil in a mature stand of red spruce (Picea rubens Sarg.). The following six microsites were designated for sampling: "open" and "closed" hollows, flats, and hummocks. "Open" and "closed" referred to the space among the tree crowns directly above the microsites. Three sampling techniques, namely core samplers, pitfalls and Tullgren funnels, were employed. Samples were collected weekly from spring to winter in 1966 and 1967 by all methods except that in 1966 Tullgren funnel samples were collectell biweekly. Collected fauna comprised five Phyla, 11 classes, 28 orders, and approximately 124 families. The transformed core sample and Tullgren funnel data were analyzed using an ANOVA (2-way classification) procedure. Transformed pitfall data required an ANOVA (2-way classification, with sampling) procedure. The core sample and Tullgren funnel methods indicated a significant difference (α = 0.10) among microsites based on total weekly (or biweekly) faunal catches in all but one case (which approached significance). In 1966 there were no significant differences (α = 0.10) among the pitfall microsites but in 1967 there were. In all cases there were significant differences (α = 0.10) in the total weekly or biweekly catches of fauna from the various microsites.

The effect of dormancy in zooplankton populations is still unknown, largely because of the lack of methods to estimate hatching and production of the dormant stages. This study aimed to compare the production and hatching rates of ephippia of Daphnia laevis between thermal stratification and mixing periods in Jacaré Lake (Middle Rio Doce, Minas Gerais, Brazil). For this, we collected ephippia on the sediment with core sampler and we created a device called the “Ephippial Collector”. There was a significant difference in ephippia hatching in situ between stratification and mixing periods (Pearson's Chi-squared test p <0.001), being higher in the second one. Significant differences in the hatching rates between periods was observed in the laboratory only for ephippia collected with Ephippial Collectors (Pearson's Chi-squared test p <0.001), being higher during the mixing period (∼8%). The core sample allows the collection of a certain fraction of the sediment that may contain a mixture of ephippia produced in different periods, i.e., may contain old and not viable ephippia, which masks the hatching rate. Thus, seasonality in hatching rates of ephippia was reported only by Ephippial Collectors. The higher hatching rate observed during the mixing period in the lake suggests that individuals hatched from ephippia may contribute to the increase in the population of D. laevis in the water column at this time.

AbstractThis study investigates certain arthropod predator elements of the soil fauna of a mature red spruce (Picea rubens Sarg.) stand. It presents differences between abundance 2 years prior to and 1 year after aerial spraying with fenitrothion at 2 and 3 oz per acre.One species of centipede, one species of pseudoscorpion, and three species of harvestmen were noted in fewer numbers during the year of spraying. Higher numbers occurred the following year. Spiders of the family Erigonidae showed no marked difference in numbers during the course of the study. Most other spiders were encountered in reduced numbers during the spray year but rebounded next year.Apparently, fenitrothion does cause temporary reduced abundance of at least some predacious arthropod components of the soil fauna. The effect of such changes in the insect community on soil processes remains unknown; even more so, the influence of repeated annual applications of fenitrothion remains undetermined.

This study aims to determine the university students’ level of motivation in terms of different variables. A study group of this research has been designed through one of the non-random sampling methods, Using appropriate sampling, 606 students from Faculty of Education of C.U. have been involved in this study. Motivation scale in English Language Learning developed by Mehdiyev,Usta,Uğurlu (2015) was used as an instrument of data collection. T-test and one - way analysis of variance (ANOVA) were used to resolve problems of this research. As a result of the research the motivation level of university students hasn’t been revealed significantly different regarding to the gender variable. However, considering the t-test results of motivation scale dimensions, confidence, attitude and personal use, significant difference is seen in favour of women in personal use dimension. The level of language learning motivation of female students is higher than men’s regarding to personal use dimension. However, men’s and women’s views don’t differ significantly in attitude and confidence dimensions. University students don’t present significant differences in terms of birth place, parent’s education level, total motivation scores and confident, attitude and personal dimensions. Students’ motivation levels are seen not to be influenced by the places such as village, provision or city where they have spent the most of their lifetime. At the same time the findings revealed that parental status variable in terms of primary, secondary and university graduates has no effects on students’ motivation.

The aim of this study is to investigate the effects of participation in a 1-week summer camp on thehopelessness and self-esteem of the university students attending Sport Sciences Faculty. Participants were 36university students assigned to experiment group using a random procedure. Coopersmith Self-esteem and Beck Hopelessness Scales were completed at the beginning and end of the summer camp by designed the university. The obtained data were analysed in the SPSS 18.0 program and the significance level was taken as 0.05. The descriptive statistics, independent simple t test, paired simple t test and Pearson correlation were used for analyse the data in the study. According to the results of the research, no significant difference was observed in the comparison of the hopelessness and self-esteem levels between pre and post-test. In addition, there was a significant difference in the hopelessness level of male and female students but any significant difference was not observed in terms of self-esteem. There was a significant relationship between hopelessness and self-esteem pre and post-test. These result shows that a 1-week summer camp cannot change the hopelessness or self-esteem level. However, as the self-esteem rises, the rate of despair decreases whereas as the despair rises, the selfesteem decreases.

AbstractBackgroundAesthetic alterations in the face can be self-perceived and can affect quality of life in young adults.ObjectiveTo assess the impact of malocclusion on self- perceived oro-facial behaviour among young adults.MethodsA Cross sectional study was conducted among 638 young adults (aged 18–21 years) of Hyderabad city. One college from each of the five zones of the Hyderabad city (five colleges) were selected by simple random sampling procedure. A 21-item Oro-facial investment scale (OFIS) questionnaire assessing self-perceived oral health knowledge, attitude, practice and Dental Aesthetic Index (DAI) assessing the severity of malocclusion was used. Data were analysed with standard statistical software (SPSS, Statistical package for the social sciences, version 20.0). p < 0.05 was considered statistically significant.ResultsMales had higher mean scores for knowledge (2.90 ± 0.49) than females (2.73 ± 0.82) and was statistically significant (p = 0.002*). No statistically significant gender differences were found in relation to attitude and practice. Analysis of variance (ANOVA) showed that there was a significant difference in all the three scores (knowledge, attitude, practice) with respect to age, with significantly high score for knowledge and practice among 18 year old subjects (p = 0.0001*; p = 0.0003* respectively) and attitude among 21 year old subjects (p = 0.0049*). No statistically significant age, gender differences were found in relation to DAI scores. Upon correlation, DAI significantly and positively correlated with knowledge (p = 0.03*) and attitude (p = 0.0001*).ConclusionThis study has shown significant impact of malocclusion on the self-perceived oro-facial behaviour.

<b><i>Introduction:</i></b> A disturbed sense of self is frequently discussed as an etiological factor for delusion symptoms in psychosis. Phenomenological approaches to psychopathology posit that lacking the sense that the self is localized within one’s bodily boundaries (disembodiment) is one of the core features of the disturbed self in psychosis. The present study examines this idea by experimentally manipulating the sense of bodily boundaries. <b><i>Methods:</i></b> Seventy-three patients with psychosis were randomly assigned to either a 10-min, guided self-massage in the experimental group (EG) to enhance the sense of bodily boundaries or a control group (CG), which massaged a fabric ring. Effects on an implicit measure (jumping to conclusion bias; JTC) and an explicit measure (Brief State Paranoia Checklist; BSPC) of delusion processes were assessed. The JTC measures the tendency to make a decision with little evidence available, and the BSPC explicitly measures the approval of paranoid beliefs. <b><i>Results:</i></b> Patients in the EG showed a lower JTC (<i>M</i> = 4.11 draws before decision) than the CG (<i>M</i> = 2.43; Cohen’s <i>d</i> = 0.64). No significant difference in the BSPC was observed. <b><i>Discussion/Conclusion:</i></b> Our results indicate that enhancing the sense of body boundaries through a self-massage can reduce an implicit bias associated with delusional ideation and correspondingly support the idea that disembodiment might be a relevant factor in the formation of psychotic symptoms.

Abstract INTRODUCTION Controversy exists as to whether telephone clinics are appropriate in neurosurgical-oncology. The COVID-19 pandemic forced neuro-oncology services worldwide to re-design and at the University Hospitals Birmingham UK, telephone clinics were quickly implemented in select patients to limit numbers of patients attending hospital. It was important to determine how these changes were perceived by patients. METHODS A 20-question patient satisfaction questionnaire was distributed to patients who attended neuro-oncology clinic in person (“face-to-face”), or via the telephone. Fisher’s exact test was used to determine significance, which was set at p&lt; 0.05. RESULTS Eighty questionnaires were distributed between June 2020 and August 2020. Overall, 50% (n=40) of patients returned the questionnaire, 50% (n=23) of face-to-face and 50% (n=17) telephone patients. Of those who received telephone consultations, 88% (n=15) felt the consultation was convenient, 88% (n=15) were satisfied with their consultation and 18% (n=3) felt they would have preferred to have a face-to-face appointment. Of those who attended clinic in person, 96% (n=22) felt their consultation was convenient, 100% (n=23) were satisfied with their consultation and 13% (n=3) would have preferred a telephone consultation. Within the face-to-face clinic attendees, only 13% (n=3) were concerned regarding the COVID risk associated with attending hospital. There was no significant difference in patient convenience or satisfaction (p=0.565 and p=0.174 respectively) between face-to-face and telephone clinics. There was no significant difference in whether patients would’ve preferred the alternative method of consultation (p &gt; 0.999). CONCLUSION Our study suggests that careful patient selection for neuro-oncology telephone clinic is not inferior to face-to-face clinic. Telephone clinic during COVID-19 pandemic proved to be convenient, safe and effective. This global health crisis has transformed telephone neuro-oncology consultations from an experimental innovation into established practice and should be continued beyond the pandemic in select cases.

Dairy science is a multidisciplinary area of scientific investigation and Ph.D. students aiming to do research in the field of animal and/or veterinary sciences must be aware of this. Ph.D. students often have vast spectra of research interests, and it is quite challenging to satisfy the expectation of all of them. The aim of this study was to establish an international Ph.D. training program based on research collaboration between the University of Sydney and the University of Padova. The core component of this program was a two-week Postgraduate Summer School in Dairy Science, which was held at the University of Padova, for Ph.D. students of both universities. Therefore, we designed a program that encompassed seminars, workshops, laboratory practical sessions, and farm visits. Participants were surveyed using a written questionnaire. Overall, participants have uniformly praised the Summer School calling it a rewarding and valuable learning experience. The Ph.D. Summer School in Dairy Science provided its participants a positive learning experience, provided them the opportunity to establish an international network, and facilitated the development of transferable skills.

The purpose of this study was to identify prevalence rates of medical problems among flautists. The Flute Health Survey (FHS), a questionnaire with items regarding musculoskeletal and nonmusculoskeletal problems, was distributed at the 1999 National Flute Association annual meeting (n = 40). This questionnaire was pilot tested at the 1999 Texas Flute Festival, which is hosted by the Texas Flute Society. The University of North Texas has posted on the Internet a similar questionnaire regarding the medical problems of all musicians. Responses from the University of North Texas Musician Health Survey (UNT-MHS) were filtered to include only those respondents who denoted flute as their primary instruments (n = 328). Data sets from both surveys were then processed using comparative statistics. Findings show that there was no significant difference between the demographics of the two populations. Only one musculoskeletal site, the left hand, was found to be statistically significant between the two groups. Four nonmusculoskeletal items, depression, earache, headache, and sleep disturbances, were found to be different between the two groups. The overall findings of this comparison show that there are many medical problems facing the flute playing community. Further investigation and observations of this population are necessary.
