As Dykstra and Silag (1985) have noted, the analysis of American frontier towns continues to yield a plethora of local histories that might provide an empirical basis for generalization, if a theoretical basis for comparative analysis might be offered. The development of a rigorous methodology for historiographie and statistical analysis has facilitated the accumulation of empirical evidence, but the analysis of local history has not advanced far beyond the initial debate regarding the basis for democratic governance (Taylor, 1956). Instead, two research traditions have developed—one seeking to identify the socio-cultural basis for community solidarity, the other focusing on the partisan struggles that shape democratic governance.

Abstract This paper describes the analyses of the fatigue life of the asphalt pavement reinforced with geogrid interlayer under traffic loading. Finite Element ANSYS package with using nCode applications, as well as macros specially designed in APDL programming script and VBA were used to model the considered problem. Our analysis included computation of stress, fatigue life, damage matrix and rainflow matrix. The method applied was the one of fatigue calculation: stress - number of cycles in short S-N. On the basis of the performed high cycle fatigue analysis, the influence of the location of the used geogrid and of its bond with asphalt layers on the fatigue life and the work of the asphalt pavement structure were determined. The study was carried out for three temperature seasons i.e. spring and fall (assumed as one season), winter and summer. The variability of the traffic conditions were taken into account by assuming weekly blocks of traffic loading. The calculations were made using the real values of loading measured in field tests on the German highways by means of HS-WIM weighing system. As a result of the performed tests, it was proved that the use of geogrid-reinforcement may prolong the fatigue life of the asphalt pavement. However, it is required that: the geogrid should be located in the tension zone as low as possible in the structure of the asphalt layers. Moreover, it is necessary to provide high stiffness of the bond between the geogrid and the asphalt layers.

Aim: It was aimed to reveal the perspectives and satisfaction levels of 4th and 5th grade-clinical students who go on practice education at Tokat Gaziosmanpaşa University Faculty of Dentistry in the 2020-2021 Academic Year. Methods: Within the scope of the study, 146 students in total, who did their face-to-face internship between October 5 and December 11, 2020, were asked to participate in an online survey with 10 questions. Clinical students were asked about their perspective on Covid-19 infection, whether they felt safe in their dental practice, their families' level of anxiety about their internship, and whether they voluntarily chose dentistry. Results: According to the survey results; 15.1% of the students agree (TA), 27.4% agree (A), 37% partially agree (PA), 13% disagree (D) with the statement “I am pleased to have internships since the beginning of the term” 7.5% of them answered, “Strongly disagree” (SD). Pearson’s chi-square test was used in the statistical analysis of the answers given by 4th and 5th-grade students to the first 9 questions of the questionnaire consisting of the same questions. According to the survey results, it was also observed that most students chose the dentistry profession of their own will (TA 39%, A 36.3%, PA 13.7%). The number of students who think they feel safe in terms of infection control during their internship is 60% in total (TA 5.5%, A 17.1%, PA 37.7%). Conclusion: Despite the increasing number of cases until today, it is thought that the process has been successfully managed and that the students have gained experience in practical training, albeit limited.

Local government units carry costs related to the shaping and spatial development of communes, and are consequently interested in sharing the benefits that land property owners gain on this account. This is possible through, inter alia, the betterment levy. The aim of this study was to determine the reasons for the discontinuation of betterment levy charging in Poland, illustrated with the example of Gorlicki County. A further aim was to classify the reasons for the discontinuation of betterment levy charging in Poland, and to suggest directions for changes in the way in which this levy is charged. A questionnaire survey was conducted of the communes of Gorlicki County (Małopolskie Voivodeship), and was completed by those responsible for charging betterment levies in the communes. According to the survey results, no decision on charging of the betterment levy was issued in Gorlicki County between 2012 and 2019. The reasons for the discontinuation of charging of this levy, as indicated by the respondents, included the lack of analyses (estimation) of the increase in the property value following the execution of specific investment activities, high administrative costs related to the charging of this levy, and the stimulation of socio-economic development. However, the statistical analysis showed that the discontinuation of charging of the betterment levy in Gorlicki County had failed to contribute to socio-economic growth.

Abstract Over the past decade professionally oriented music education in Latvia has undergone a series of reforms, which significantly affects the collective musical place and role. Aim of the present study: explore the theoretical basis and the further development of collective musical promotion. Materials and methods: The study was conducted in several stages. Originally analyzed scientific literature and training programs for Latvian cultural institutions to develop a theoretical basis 1 - 4th grade professional orientation of Instrument program content creation. Researched were study programs in Latvian universities, which acquired music pedagogy. The next stage of the research were interviewed employers, music teachers and students - future music teachers and, based on the survey results, the creation of new qualifications and new courses in a number of higher education programs. Conclusions: 1. Involving learners in the collective musical process, they are provided (ensured) the ability to comprehensively develop the musical, both in general and also the movement of psychophysiological abilities. 2. Collective musical process develops the essential skills such as socialization, cooperation partners and listening skills. 3. Learners are formed as a personality by acting in musical collective, they develop different skills. 4. Students learning motivation creation and promotion is very important. Musical collective process involved not only contributes to motivation, but creates opportunities for self-realization, without which one can not become filled and self-contained.

For the design of pavement structure the subgrade soil and its properties are important as it gives adequate support to the pavement. To increase the life of pavement the subgrade must be able to support loads transmitted from pavement structure without excessive deformation under adverse climatic and traffic conditions. For using the soil as a good quality pavement material, it is a well-known fact that all soils do not possess all the desirable qualities. The subgrade performance of such soils should be increased by several modification techniques, when such soils cannot be replaced. Among that providing reinforcement to improve subgrade soil nowadays is widely adopted. Nowadays many reinforcing techniques are used to reinforce the soil, among that coir geotextile is most widely used. As it is a natural geotextile it needs treatment to improve the durability. In this study woven coir geotextile are used as soil reinforcement to improve the subgrade soil. The improvement in CBR value when coir geotextile placed at different depth in CBR mould is studied. The coir geocells with an aspect ratio of 0.75, 1 and 1.33 is used. The maximum improvement in CBR value is obtained when geotextile is placed at 1/3H. The CBR value improved when treated coir geotextile is used and the percentage improvement is 66.8% for coir geotextiles placed 1/3H and the percentage increase for treated coir geocells when placed at 1/3H is 37.5%. The optimum height of coir geocells is obtained at an aspect ratio of 1.

The paper examines the use of free trade agreements (FTAs) by Japanese firms. The FTAs analyzed include Japan's FTAs with Mexico, Malaysia and Chile. Based on 1,688 responses to a questionnaire survey conducted in 2008, the study finds that the utilization rate of FTAs ranges between 32.9% (Japan-Mexico FTA) and 12.2% (Japan-Malaysia FTA). The survey results and the statistical analysis of the determinants of the use of FTAs reveal obstacles to using FTAs that include difficulty in obtaining the certificate of origin that is required to use the FTA, lack of knowledge of FTAs, and the small FTA tariff preference that is the difference between the most-favored-nation (MFN) and FTA tariff rates.

A Review of: Kennedy, M.R., & Brancolini, K.R. (2018). Academic librarian research: An update to a survey of attitudes, involvement, and perceived capabilities. College and Research Libraries, 79(6), 822-851. https://doi.org/10.5860/crl.79.6.822 Abstract Objective – To examine academic librarians’ current attitudes and preparedness to conduct research in order to update the knowledge gained from the authors’ 2010 survey, and to determine if changes were needed in their Institute for Research Design in Librarianship continuing education curriculum. Design – Web based survey. Setting – Institutions that employ academic and/or research librarians. Subjects – 793 academic and research librarians. Methods – The researchers posted a call for participation in their 2015 Librarian Research survey on listservs where academic and research librarians are members. The survey expanded upon the authors’ 2010 survey by adding questions to more fully explore three areas: research self-efficacy; Master’s thesis and statistics courses, and; research mentoring and institutional support. 793 librarians responded to the survey, and 669 of these respondents completed it. All data from incomplete surveys was included in the analysis. Survey results were compared with the results from the 2010 survey as well as with the responses from a survey conducted in 2000 by Powel, Baker, and Mika, which addressed many of the same topics under investigation. Main Results – The authors analyzed the survey results based on four areas: the current research practice of responding academic librarians; a self-evaluation of their confidence in performing the steps in the research process; methods training courses in which they have participated, and; demographics and institutional data related to support of library research.    Regarding current research practices, 84% of respondents said it is assumed that they will read research-based literature as part of their job as academic librarians; 80% are allowed time at work for this purpose; 6% did not know if it was assumed that they will read research-based literature as part of their job; and 9% were unsure if they were allowed to use work time to read the literature. 78% scan tables of contents for research-based journals, while 58% regularly read the full content of these articles (this is a significant drop from the 78% who reported that they regularly read full text articles in the 2010 survey). Time was the primary reason cited for not regularly reading research-based literature. 77% of respondents have conducted research since completing their Library Science degree (although 2% did not have a Master’s degree).  Respondents rated their confidence on a scale of one to five, with one being “Not at all confident” and five being “Very confident.” Overall, there were 38 components related to the steps in the research process, which were grouped into 8 questions on the survey.  For these questions, an average rating of 3.41 was calculated. From statistical analysis, the authors determined that there is a significant correlation between conducting research and librarian confidence in the process. The survey contained seven questions related to methods training. The authors were specifically interested in the correlation between librarians having conducted research since completing their degree and librarians’ belief that their degree adequately prepared them to do so. Statistical analysis revealed that the relationship between these factors was not significant; this result was consistent with the results from the authors’ 2010 survey as well as from the findings of Powell, Baker, and Mika. The authors were also curious as to whether librarians who had written a thesis as part of their Library Science degree were more likely to have conducted research since earning their degree. This relationship between these variables was not significant, however the relationship between writing a thesis for another graduate degree and conducting research was significant. Conclusion – The number of survey responses indicates that research is still a current, important issue for academic and research librarians. The authors will use the information from the surveys to revise their educational curriculum, specifically in the areas of current research practice, librarian confidence, and methods training.
