Abstract One hundred eighteen sources of eastern redcedar and 26 sources of Rocky Mountain juniper were established as a provenance test near Brookings, SD, in 1980. Height, crown width, survival, branch angle, foliage density, number of terminal leaders, sex, flowering, and the incidence of three diseases were recorded after 10 yr. ANOVA, Chi-square, simple and rank correlation, cluster analysis, and discriminant analysis techniques were used to analyze the data. Eastern redcedar exhibited better overall performance for windbreak purposes than Rocky Mountain juniper. Eastern redcedar originating in central Nebraska exhibited the best combination of height, survival and crown characteristics. Much of the eastern redcedar planted in the Great Plains 30 or more years ago appears to have been grown from seed collected in central Nebraska. Selection for fast growing sources may begin 2 or 3 yr after field planting, while the ability to select fast growing individuals within sources was only moderate after 5 yr. Correlations among traits after 10 yr were generally weak. North. J. Appl. For. 12(1):30-35.

Abstract Eastern redcedar and Rocky Mountain juniper are the two most commonly planted conifers east of the Black Hills in South Dakota. They are also planted in large numbers throughout the rest of the Great Plains. Despite their widespread use, practical genetic information for these species is limited. A regional provenance test of 118 eastern redcedar and 26 Rocky Mountain juniper sources was established in eastern South Dakota in 1980 to address this problem. Eastern redcedar exhibited better combinations of traits, with greater height growth, larger crown spread, a wider branch angle, and a stronger tendency toward producing a single terminal leader than Rocky Mountain juniper. Based on a windbreak suitability index the best performing seedlots collected from natural stands were all eastern redcedar from a large area of the central Great Plains. These results indicate that eastern redcedar should be favored over Rocky Mountain juniper for planting in eastern South Dakota. Sources of eastern redcedar south of central Kansas should be avoided.

Although the issue of corporate culture has been taken over and addressed in the literature from various perspectives, there are very few researchers about the role of leadership and motivation in it, respectively very few researchers have addressed them as important components of the international company’s corporate culture. The present paper aims to point out that leadership and motivation can be perceived as important aspects of the international company’s corporate culture. The object of the investigation was an international company (situated in Italy) and its five subsidiaries (situated in Italy, Czech Republic, Germany, and Turkey). As the main research method, there was chosen the method of the questionnaire survey, which was attempted by all the company’s employees (totally 270 respondents). The questionnaire was divided into three separate, but logically related parts—leadership, motivation, and corporate culture, and submitted to two groups of respondents—the company’s management and its employees. In total 11 hypotheses were formulated and further evaluated by the methods of Pearson Chi-square Test, Fisher’s Exact Test, Cramer’s V coefficient, Kendall rank correlation coefficient, Eta coefficient, Spearman coefficient, Mann–Whitney U test and Wilcoxon W statistics, Kruskal–Wallis test, and Friedman’s test. The results of the research have proven that leadership and motivation are important parts of the corporate culture.

Background: Almost half of the pregnancies are usually unintended. Inappropriate spacing between pregnancies can lead to maternal and neonatal complications. Awareness and education plays, a major role in combating this issue. This study was aimed to assess the knowledge and attitude regarding spacing methods of contraception among primipara mothers of Kolhapur. Material and methods: The descriptive study was performed on 110 primipara mothers admitted in hospitals of Kolhapur. A pre-validated study tool consisting of a questionnaire and a Likert attitude scale was used to assess knowledge and attitude of participants. Chi-square and Spearman's rank correlation test was used to nd the association and correlation between variables. Results: Good knowledge score was observed in 5.45% participants whereas, average and poor knowledge score found in 70% and 24.55% of participants respectively. A favorable attitude was noted in 53.6% of mothers and moderately favorable attitudes and unfavorable attitudes were observed in 43.6% and 2.7% mothers respectively. Asignicant positive correlation was observed between the knowledge score and attitude score -05 of primipara mothers (r=0.379, P=4.326e ). A signicant association of knowledge score (P<0.01) and attitude score (P<0.01) with the sociodemography of the participants was observed. Conclusion: Most of the primipara mothers had a favorable attitude regarding spacing methods of contraception but they are lacking in knowledge. The Socio-demography of the participants was signicantly associated with knowledge and attitude scores.

Introduction. The use of age- and risk-adjusted caries prevention requires up-to-date knowledge on the cariostatic effects of fluoride, as well as the methods and safety of fluoride prophylaxis. Aim. The aim of the study was to assess dentists’ knowledge of the safety and mechanism of anticaries effects of fluoride. Material and methods. An anonymous questionnaire was conducted among 212 dentists participating in dental training. The questions included in the questionnaire related to knowledge about water fluoridation, fluoride cariostatic mechanisms and the safety of fluoride prophylaxis. The chi-square test and the Spearman’s rank correlation coefficient were used for statistical analysis. A significance level of 0.05 was used. Results. Incorrect knowledge about water fluoridation was demonstrated by 26.9% of respondents in the country and 16.0% of respondents in Europe. Most respondents (80.7%) reported higher efficacy of exogenous vs endogenous anticaries approaches, and more than half of respondents (59.0%) considered the processes of remineralisation and demineralisation as the most important anticaries activity. Almost all respondents (95.7%) agreed that the use of fluoride for caries prevention is controversial, mainly due to its dose-dependent therapeutic or toxic effects (85.4%). According to about 20% of respondents, cariostatic fluoride doses have adverse effects on the general health, mainly in the form of bone fragility (10.4%). Conclusions. Lack of correct knowledge about the dominant cariostatic effects of fluoride may result in the choice of an inappropriate preventive method or avoiding local application of fluoride preparations for fear of adverse systemic effects, which may in turn lead to increased caries prevalence in a given population.

AbstractIntroduction. There are many factors which determine the attractiveness of a region for tourists. However, such assessments are, relatively rarely, a result of the analysis of the presence and condition of regional tourist brands and their perception among visitors. The analysis and assessment of the condition of a brand can be carried out using the BAV (Brand Asset Valuator). This is an extremely interesting and useful tool which explains the dynamics of behaviour of brands on the market and diagnoses their “health”, supporting the process of their long-term management.Materials and methods. On the basis of the results of a pilot study, an attempt is made to measure the tourist attractiveness of the Podkarpackie region through the assessment of regional tourist brands and their features which are important from the point of view of the inhabitants of the region. The BAV model was used to analyse 32 tourist products. The applied research methods include the Mann-Whitney test, Spearman’s rank correlation coefficient, and the chi-square independence test.Results. The mapped data analysis based on the BAV model showed that 16 out of 32 products assessed were located in the leadership quadrant. The majority of the remaining products were in the development or decline phases.Conclusions. The presence of branded tourist products and their number have an impact on the tourist attractiveness of the region. The following aspects of the region were considered the most attractive: nature (natural surroundings, natural values, and ecological aspects), heritage (historical heritage and monuments and presentation of important past events), and tourism (tourism and recreation offerings).

The world of research requires researchers, students to share knowledge. With the invention of social media, knowledge sharing process has been more effective and easier. This study examined the usage of social media for knowledge sharing among students of the Polytechnic Ibadan, Nigeria. Descriptive survey research design was adopted, while stratified random sampling technique was adopted to select the students. Four hundred and thirty four copies of questionnaire were administered, while 301 were retrieved and 271 copies found useful for data analysis. Data was analysed using frequencies and percentage distribution, Spearman’s rank correlation, Kruskal Wallis test, and Chi-Square. Findings reveal that Facebook and Whatsapp are the widely used social media tools for knowledge sharing by the students. The study found significant relationship between social influence and attitude towards using social media for knowledge sharing, as well as significant relationship between attitude and use of social media for knowledge sharing.The study recommends that institutions should exploit the proliferation of social media and its use to set up off-class student-student and student-lecturer discussion groups, which could help encourage and promote knowledge sharing, and thereby help students in achieving good academic outcomes.

Purpose: The purpose of this study was to assess the knowledge of pharmacists practicing in Palestine of issues related to using psychotropic medications in older people. Methods: The study was conducted with a cross-sectional observational design using a questionnaire. A total of 400 pharmacists responded to a 19-statement knowledge test related to the use of psychotropic medications in older people. The study was conducted from July 2016 to February 2017. The reliability and internal consistency of the study tool was assessed using the test-retest method and the Cronbach alpha. Categorical groups were compared using the chi-square test and the Spearman rank correlation. Results: On the 19-statement knowledge test, the median score was 55.3% with an interquartile range of 21.9%. In a comparison of the demographic and practice-related variables of the pharmacists who scored ≥ 50% on the 19-statement knowledge test with those who scored < 50%, age, gender, and having taken a course on psychotropic medications were found to be significantly associated with performance, as shown by the chi-square test and Spearman correlation. Conclusion: Pharmacists practicing in Palestine possess less than optimal knowledge of issues related to the use of psychotropic medications in older people. Continuing educational interventions and/or training might be helpful in improving pharmacists’ knowledge of issues related to using psychotropic medications in older people.

Orientation: This article provides an explorative analysis of the use of the job enrichment technique for decision-making in higher education in the Philippines.Research purpose: The profile of administrators in charge of decision-making was investigated in terms of their level of familiarity with, and use of, this technique in achieving the goals of enriching jobs, retaining staff and ensuring job-motivation in higher education.Motivation for the study: Given the increasingly competitive higher education environment in which higher education employees, including academics, work, the pressure on their performance, and their search for ideal working conditions, it is important to measure the impact of the job enrichment technique on employee and higher education organisations.Research design, approach and method: The study used a quantitative method. The respondents of this study consisted of 206 administrators. Spearman Rank, Correlation Coefficient, Point Bi serial and Chi-square were used to analyse the relationships between the demographic characteristics and job enrichment technique. Multiple Regression Coefficient was used to predict job enrichment.Main findings: The findings suggest that educational attainment and experience are the most important factors for predicting success as an administrator in higher education.Practical and managerial implications: Job enrichment should not only focus on the knowledge, experience and skills of administrators, but should be extended to encompass the context and working conditions of employees.Contribution: In the context of fiscal austerity measures that result in fewer resources becoming available for higher education, it is important to have competent decision-makers who are able to motivate staff.

The Middle to Late Eocene sediments of Texas have yielded a wealth of fossil material that offers a rare window on a diverse and highly endemic mammalian fauna from that time in the southern part of North America. These faunal data are particularly significant because the narrative of mammalian evolution in the Paleogene of North America has traditionally been dominated by taxa that are known from higher latitudes, primarily in the Rocky Mountain and northern Great Plains regions. Here we report on the affinities of two peculiar carnivoraforms from the Chambers Tuff of Trans-Pecos, Texas, that were first described 30 years ago as Miacis cognitus and M. australis . Re-examination of previously described specimens and their inclusion in a cladistic analysis revealed the two taxa to be diminutive basal amphicyonids; as such, they are assigned to new genera Gustafsonia and Angelarctocyon , respectively. These two taxa fill in some of the morphological gaps between the earliest-known amphicyonid genus, Daphoenus , and other Middle-Eocene carnivoraforms, and lend additional support for a basal caniform position of the beardogs outside the Canoidea. The amphicyonid lineage had evidently given rise to at least five rather distinct forms by the end of the Middle Eocene. Their precise geographical origin remains uncertain, but it is plausible that southern North America served as an important stage for a very early phase of amphicyonid radiation.
