The forests of beech and fir (with spruce), as the most wider spread in Bosnia and Herzegovina (occupy 562.237 ha, i.e. more than 35% of the forest surface in Bosnia and Herzegovina – MATIĆ ET AL. 1971), have been the subject of numerous researches among which the phytocenological research has great significance. However, lots of questions have not been solved regarding some groups of forests in terms of their ecological circumstances, floristic structure, mutual relationships as well as syntaxonomic position. The forest of beech and fir on basic eruptives, gabbro and diabas, in ophiolite zone in Bosnia, belong to this group.

Ecological circumstances, especially edaphic conditions, in which these forests arise, show some specific qualities in relation to other substratum where the forests of beech and fir (with spruce) are found, which affects the floristic structure and substance of these forests as well as their syntaxonomic classification.

The research of the diversity, structure and texture was performed on the mountain Grmeè in western Bosnia, in the summer and fall of 2007, in the virgin forest and in the managed forest of beech and fir with spruce. For the research purposes, a systematic network of experimental circles within the distance of 1 x 1 km was installed in the managed forest. On the intersection of the squares network, 14 circular surfaces of 25 m radius were installed. All circular surfaces were placed in different sections. In the virgin forest a permanent experimental surface of size 100 x 100 m was set, with surface of 1 ha and one circular surface of radius 25 m, with surface of 1963 m2. The research determined the horizontal (opposing) and vertical structure, the diversity, the quality of the resources and the health of the virgin forest plus the managed forest. The texture was determined only for the virgin forest. The diversity of the tree types over the number of trunks in the virgin forest is 1,79, in the managed forest 1,78, over the basal; these indexes for the virgin forest are 1,24 and for the managed forest 1,64. The virgin forest has a poorer structure of tree resources compared to the managed forest, but is of better health. In the managed forest there are many trunks of suspicious health, as much as 35,8 %. The texture diversity in the virgin forest is 2,43.

The time period of forests opening and construction of forest truck roads in the analyzed area is longer than half of century. In such long time interval different types of vehicles for transport of timber assortments have been applied. Due to this fact technical elements of constructed roads are different. The vehicles currently used for the transport of timber assortments cause an accelerated destruction of forest truck roads due to inappropriate carriage way quality. Besides traffic load the forest truck roads are exposed to permanent atmospheric influences. The above specified and other reasons condition obligatory and regular maintenance and reconstruction of forest truck roads depends on the current condition of forest truck roads as well as on the plans for further use.

In this article the condition of forest truck roads in the Forest management regions of Sarajevo Canton has been determined. The most frequent types of damages and causes of their occurrence have been registered. The methods for maintenance and rehabilitation-reconstruction of forest truck roads have been selected and their costs have been calculated.

Protected areas have significant role in protection of biodiversity, social and cultural values followed by improvement of life standard of local population. As a country with economy in transition, Bosnia and Herzegovina is trying to follow globally increasing trends in nature protection. Yet, Bosnia and Herzegovina belongs to the group of countries that have difficulties to meet European criteria for minimal percentage of protected areas. Although in the last two decades numerous initiatives for proclamation of protected areas have been launched, the percentage of protected areas is still far from the European average. Establishment of new protected areas is often followed with certain misunderstandings between interest groups, lack of participation, transparency and involvement of all interest groups. The concept of cross-sectoral cooperation imply interaction between different interest groups in specific area characterized by efforts, cooperation and responsibility in order to accomplish joint consensus about the improvement of management of natural resources. This paper is focusing on the concept of cross-sectoral cooperation through the analysis of its implementation in management of National park "Una", as the youngest proclaimed National park in Bosnia and Herzegovina. The attitudes of interest groups related to cross-sectoral cooperation will be discussed together with proposal of several activities for improvement of cross-sectoral cooperation in National park "Una". Results could be useful for key decision makers in nature protection sector and institutions responsible for management of protected areas to recognize importance of cross-sectoral cooperation and promote its implementation and everyday practice.

The position of the Illyrian vegetation provinces in the Western Balkans was established a long time ago (e.g.: BECK 1901, ADAMOVIĆ 1907…) Illyrian space is linked to: Montenegro, Bosnia and Herzegovina, Croatia and Slovenia. Karawanke – An alpine mountain represents the border between Austria and Slovenia but also represents a border area of ​​the Illyrian provinces. Determining phytogeographical affiliation forest communities of beech becomes very important from the aspect of protection under Natura 2000. According to the requirements Nautra 2000 Illyrian beech forests (91K0 - alliance: Aremonio - Fagion), are summaries of interest for protection in Austria. Therefore, it is important to determine vegetational - floristic characteristics of beech forests on Karawankas, from which one could conclude their phytogeographical affiliation. The research in beech forest, (forestry office Hollenburg) have showed the following beech community Anemone trifoliae - Fagetum laricetosum TREGUBOV 1957 (syn.: Larici - Fagetum ROBIČ 1971 /n.nudum./ and syn .: Fagetum subalpinum var. geogr. Larix decidua MARINČEK, POLDINI, ZUPANČIČ 1986); Anemone trifoliae - Fagetum typicum TREGUBOV 1957 var. Carex alba MARINČEK, POLDINI, ZUPANČIČ 1986; Salvio Glutinosae - Fagetum ZUKRIGl, 1988. Based on floristic characteristics, their structure, syndinamics, it can be concluded that the first two beech communities cannot be classified as the Illyrian beech forests, while community Salvio glutinosae - Fagetum shows similarity with the Illyrian beech forests fresh Aremonio - Fagion (Natura 2000 at 91K0).

Phenolic contents of methanolic extracts prepared from leaves and fruits of Crataegus monogyna Jacq. and Crataegus macrocarpa Hegetschw. were determined. The antioxidant capacity was assessed by DPPH, ABTS and FRAP assay. The results showed that leaves were richer in the content of phenols (59.23 - 91.91 GAE g-1), flavonoids (2.38 - 4.08 mg QE g-1 and 5.24 - 8.9 mg RE g-1) , phenolic acids (33.40 - 68.98 CAE g-1) and proanthocyanidins (26.15 - 48.60 CE g-1) while in fruits anthocyanins dominateted (0.43 - 0.80 CG g-1). Leaves also had higher antioxidant capacity than fruits for both species. Generelly, C. monogyna fruits had higher content of anthocyanins. Total phenols, phenolic acids and proanthocyanidins were highly corelated with DPPH (r2 = 0.8703 - 0.9618), ABTS (r2 = 0.7833 - 0.9443) and FRAP (r2 = 0.903 - 0.9695) assay. The results suggests that these compounds were the major contributors to the antioxidant capacity in leaves and fruits extracts of both species.

Higher contents of bioactive compounds and higher antioxidant capacity were determined for C. x macrocarpa samples. Therefore, C. x macrocarpa leaves and fruits are valuble source of antioxidant polyphenols with high potential for use in preparation of different natural health products.

Social, economical and political changes in South-east European countries have led to significant shift from traditional pattern of forest policy to new, more complex paradigm when it comes to forestry and forest resources management. Among other things, this implies increasing of private forest owners’ heterogeneity which is reflected in changes of their expectations, objectives, attitudes and management practices. In this context, it is important to explore how private forest owners obtain information useful for forest management but also to analyze in which way their characteristics influence fulfilling of informational needs. The objective of this paper was to analyse sources of information that private forest owners are most likely to use, and to assess how owners’ characteristics, property conditions as well as management behaviour, affect it. Surveys were conducted in Bosnia-Herzegovina (n=350), Serbia (n=350), Croatia (n=350) and Slovenia (n=322) on random samples of private forest owners while the data were analysed by using logistic regression model. The paper examined five models of information providers: private forest owners associations (1), relatives (2), public forest administration (3), other owners (4) and public forest companies (5). Comparison between countries indicates the differences regarding to informational providers, caused mainly due to importance of private forests to their owners and different organizational structure of national forest sectors. Comparing to other countries, it seems that Slovenian private forest owners are more active in searching for information. Public forest administration is the most preferable provider of information in Slovenia while in Bosnia-Herzegovina these are public forest companies and public forest administration. In Serbia and Croatia the most common providers of information are public forest companies. Only Slovenian private forest owners use interest associations as the source of information. The traditional providers of information (other owners) are still important for private forest owners in Slovenia and Bosnia-Herzegovina at least. The results of logistic regression models reveal that forest property size, fragmentation, harvesting activities as well as owners’ age influence the source of information that private forest owners are most likely to use. The model 3 (pubic forest administration) is statistically significant in Slovenia and Bosnia-Herzegovina, while in Serbia and Bosnia-Herzegovina the model 5 (public forest company) is significant. None of the models is statistically significant for Croatia. Besides, the model 4 (other owners) was statistically significant in Slovenia.

Regular forest inventory on state owned forest delivers plenty of data and information enabling detailed insight in forest structure and quantities. Current methodology for forest assessment on private properties considers time-consuming, low-intensive terrestrial measurement and observation on scattered small forest stands distributed on hilly and plane position around complex of state owned forests.

Here are evaluated two modeling techniques: ordinary least square (OLS) regression and geographically weighted regression (GWR) estimating growing stock quantities of point sample inside the smallest state owned forest stands (area less then 10 ha). Used material contained forest attributes local estimates from regular inventory distributed in unique management class: beech and fir mixed forest on deep silicate soil, environmental and transformed spectral Landsat 8 data.

Obtained results pointed out statistical significance of normalized standardized spectral radiance of NIR and SWIR Landsat bands in regression models. The GWR estimates achieve up to almost 30% higher variability explanation then OLS models. Also, GWR showed wider range then OLS estimates with smaller prediction errors. Evaluation on sample stand level resulted in reliable estimates of particular species or groups and total mean growing stock for all small stands. Further research about potential of GWR and other geo-statistical techniques for forest attribute estimates on more intensive point sample inside small spatial unit and/or whole spatial unit is recommended.

Phenolic compounds content and antioxidant capacity from Viscum album ssp. album Beck. leaves and twigs extracts were determined. Common mistletoe was collected from four hosts (Crataegus monogyna, Malus domestica, Prunus cerasifera, and Populus x canadensis.). Folin-Ciocalteu method, AlCl3 method, method with Arnow reagent, and acid-butanol assay were applied for determination of total phenols, flavonoids, phenolic acids and proanthocyanidins respectively. DPPH, ABTS and FRAP methods were applied in the determination of antioxidant capacity of the extracts. Total phenols were in the range 7.16-11.70 mg GAE/g DW, flavonoids 2.115-4.668 mg RE/g DW, phenolic acids 0.811-1.789 mg caffeic CAE/g DW, and proanthocyanidins 0.71-2.62 mg LCE/g DW. Content of phenols and flavonoids was higher in the leaves than the twigs. The highest antioxidant capacity in leaves (50.86-65.93 µmol Trolox equivalents/g DW) was determined for mistletoe collected from Crataegus monogyna while the highest capacity in twigs had mistletoe collected from Malus domestica (67.28-81.72 µmol Trolox equivalents/g DW). Also, high correlation has been noticed between total phenols, flavonoids, phenolic acids and antioxidant capacity for V. album leaves. For twigs, high correlation was obtained between phenols and antioxidant capacity, and in some moderate extends for proanthocyanidins.

Biomass has a huge renewable energy source potential, forest biomass in particular. Forest biomass effectively includes aboveground parts of tree trunk including: stem, treetop with leaves/needles, bark, seeds, and cones. Although it is biomass, stump is not used in natural forests. Beech (Fagus sylvatica L.) is a dominant tree in the forests of Bosnia and Herzegovina and it is important raw material used in wood assortment production. Once beech assortment is cut down, processing and hauled there is a significant quantity of unused wood biomass which can be effectively used as source of renewable energy. This is way the objective of this paper was to determine overall quantity of beech tree biomass in Compartment 92, Subcompartment „a”, MU „Žuća-Ribnica“, assess quantity of forest biomass (usable timber left after felling and branches - biomass above 7 cm), determine quantity of forest biomass (wood biomass from 3 to 7 cm), and also quantity of bark. The research included 60 beech trees. Volume of tree trunk and trunk bark was determined by sectioning method and branch mass was determined by weighting. Adjusted values of tree trunk and bark volumes were converted in dry matter mass using information provided by. The research findings showed that 73% (1,605.24 tons) of beech wood biomass is used in Compartment 92, Subcompartment „a”, MU „Žuća-Ribnica“, while 27% (582.59 tons) remain unused in the forest. This altogether indicates that a large portion of beech biomass is not used as energy source.

Road networks within the forested areas are essential structure to access forests for various purposes such as management, protection, regeneration, harvesting, and recreation etc. However, if roads are not planned properly, they may result in serious impacts on forest ecosystems including degradation and fragmentation of habitats. On the other hand, light availability along the road edge increases which reflects the diversity and amount of plant species. In the study, it was aimed to investigate the rod edge effect on tree growing by measuring the basal area increment along road network located within the linden stands. The study area was selected from Karacabey province of Bursa where linden has the largest distribution in Turkey. In the field study stage, four sample trees were selected from 5-meter-wide stripes at the road edge and from control zone which is about 50 meters away from the road edge. Measurements were repeated for 6 sample road sections with 500 meters length along 3 km-long road located in the middle of linden stands. Since the stand characteristics were mostly uniform and did not vary significantly along the sample road, stand structures such as tree ages, stand density, canopy, etc. were not   evaluated in this study. During the data collection, the diameter at breast height (DBH) was measured for the sample trees located in the specified zones. Then, statistical analysis was conducted to indicate whether there is a difference in basal area increments between the trees at road edge and the trees located in control zone.  According to the results, increasing the distance from the road edge resulted in reduction in the average basal area values. There was a statistically significant difference between basal area values for trees at road edge and the trees located in control zone.

Perdix perdix L. (also known as the Grey partridge, English partridge, and Hungarian partridge) populations have been declining for years in natural habitats and areas in which this species of wildlife has been introduced. Hunting grounds at the base of Mt. Fruška Gora and Sremska Rača in the Republic of Serbia provide excellent conditions for its breeding. In addition to the data from hunting records about population quantity of the P. perdix, a direct monitoring allows a relevant inside to its' quantity in hunting associations’ hunting grounds. The decline of population quantity is mostly the result of the use of chemicals for protection of agricultural crops (10%), destruction of nests and bird eggs (12.5%), and the failure to implement failure wildlife-protection measures, by forbidding the hunt of P. perdix  (5%) , and the use of poisons on agricultural crops, such as the forbidden poison Furadan (5%). Although no significant results have been obtained on the impact of predators and abandoned animals on the reduction of P. perdix population, there is a justified concern by hunting associations’ in terms of finding ecologically and biologically viable solutions for impact on predators on feathered game, and especially abandoned dogs. The results of the study were obtained by the method of directly determining the number of P. perdix in the crop fields, in the hunting grounds of L.D. "Fazan Mala Remeta", L.D. "Fazan" Jazak, L.D. "Stejanovci" Stejanovci, L.D. "Zec" Vrdnik and L.D. "Srndać" Sremska Rača.

In certain institutions, the experiments of online systems were successful while in certain cases difficulties were observed and reported. In this paper, we are interested to highlight and analyze the problems occurring in assessment and evaluation. The delivery of lectures and grades assessment, comparison of time spent on in-class lectures and online, the provided infrastructure and technology to faculty and its synchronization with that arranged by students. The objective type questions are automatically marked by the system for example Moodle, whereas the essay type (subjective type) questions are normally preferred to be marked by faculty on the system. This is indeed a facility that all students are provided with different question papers.  The online system is more economical, time-saving and easily usable. The most serious issues have been unfair means and cheating used by students during examinations. A detailed analysis of the state-of-the-art is presented in this paper. We also present a comparison of online and in-class teaching and assessment, but irresistibly the benefits of online system are more advantageous. For example, a lot of stationary is saved. The online system causes breaks and pauses during delivery of lessons due to instability of internet and concavity issues. The most important is the choice concerning system subject to available facility with leaner and the faculty and its compatibility with emphasis on technology. The use of anti-cheating software makes the examination secure.
Traffic Intensity Based Energy Efficiency Architecture for Data-Centers
Authors: Salman Qadri
Published: January 2022

The world is moving towards cost-effective and time-constrained solutions. The uses of applications and automated devices have been growing day by day. In computing, resources available in personal computers are limited due to less storage capacity and lower computation speeds. Using all applications on personal systems may not be cost-effective. Therefore, the trends of online storage and computing have become popular. On the other hand, there must be some serving end for these users. One of the major issues, due to the growth of data centers is the increase in power usage of a larger number of servers and network devices. These devices are power-hungry and consume energy even during idle hours even if there are no network traffic loads. The cost of energy used and dissipated is increased in this situation. In this paper, we have given a solution for efficient usage of energy efficiency in data center networks based on traffic loads. We have proposed a model to use traffic intensity to decide the number of machines inactive conditions so that we can save the energy consumption in data center networks. We have implemented this proposed model and simulated it to validate it.

Heavy Metal Contamination of groundwater is an issue of deep concern worldwide and as such the degree to which these metals have contaminated the most valuable fresh water resource “GROUNDWATER” must be summarily understood. 10 Borehole water samples were taken from various parts of Agbor and analysis were carried out for the major anions and cations with Arsenic been the heavy metal of interest. Upon comparison with NIS and WHO standards for drinking water, the results shows that though they were measurable concentration of Arsenic in three locations but they were high enough to pose threat to human health. Nonetheless, the results were subjected to Statistical Analysis using Principal component Analysis (PCA) to standardized data sets. The results gotten was tied to graphical methods, Stiff plot and Piper diagram to obtain the water type as Ca2+-Mg2+-Cl- - SO42- and revealed the dominant ions. PCA revealed that five components control the hydrochemistry of the study area.Ammonium,Nitrate,Phosphate and TDS dominated component 1 which accounted for 41.1%,Chloride, sulphate and EC are parameters in component 2, component 3 hasCalcium, Magnesium and Bicarbonates, component 4 isdominated bypH and component 5 holds potassium and sodium accountable for hydrochemical variation. United States Environmental Protection Agency (US EPA 2012) and EU 1998 Standards were compared with parameters to ascertain the quality of the water for domestic use. pH had a value less than 6.5 for most of the sampled locations and these were out of range of US United States Environmentaal Protection Agency (EPA) and European Union Drinking Water Directives(EU DWD) standards

O presente artigo visa analisar como os Programas de Pós-Graduação (PPGs) em Contabilidade abordam a temática da avaliação da aprendizagem em suas disciplinas de formação docente. Por meio de uma pesquisa documental, foram analisadas as ementas das disciplinas de formação docente oferecidas pelos PPGs em Contabilidade do Brasil relacionados na última Avaliação Quadrienal (2013-2016). De forma geral, observou-se um número expressivo de disciplinas que abordam a temática, um caráter tecnicista e não reflexivo nas discussões sobre a avaliação da aprendizagem e a ausência de discussões sobre novas formas de avaliação e a sua integração às tecnologias educacionais. Assim sendo, a carência de preparação adequada pode levar a realização de práticas avaliativas que reforçam a avaliação como instrumento de poder em sala de aula e que privilegiam a aprendizagem memorística em detrimento da aprendizagem significativa. O presente trabalho contribui ao aprofundar as discussões sobre uma importante prática no exercício da docência e ao possibilitar, aos coordenadores de programas e aos docentes formadores, uma visão crítica acerca do tema nas disciplinas pedagógicas, uma reflexão crítica sobre a própria prática docente e sobre a formação de mestres e doutores em Contabilidade.

O trabalho visa identificar o campo científico das pesquisas sobre conexões políticas no Brasil. Para tanto, utiliza-se da análise bibliométrica e de redes sociais para sistematizar o que foi produzido, identificar os pesquisadores, as instituições de ensino e discutir os pontos de inflexão propostos pelos achados. Adota-se como perspectiva de análise a teorização sobre a formação do campo científico de Bourdieu (1983). Os resultados revelam a concentração das pesquisas entre autores, instituições e temáticas sugerindo endogeneidade do campo com viés de abertura e mudanças a partir de 2017. Os achados indicam que o campo científico ainda não está consolidado devido a baixa densidade das redes de coautoria, concentração dos estudos em três principais pesquisadores e instituições de ensino. As temáticas desenvolvidas tangenciam os efeitos das conexões políticas no desempenho, endividamento e nos investimentos empresariais, quando abordado por pesquisadores da área de administração; e os efeitos na evidenciação de informações contábeis e no gerenciamento de resultados, quando analisados por estudiosos da área contábil. Os resultados ainda são antagônicos e podem servir como referência para que novos estudos possam preencher as lacunas existentes.
PESQUISAS SOBRE A CADEIA PRODUTIVA DO CAFÉ: UMA ANÁLISE BIBLIOMÉTRICA DA LITERATURA NA ÁREA DE ADMINISTRAÇÃO
Authors: Souza Ariany Pena , Bueno Janaina Maria
Published: January 2022

O Brasil é o maior produtor e exportador de café do mundo, o segundo país com maior consumo de café (USDA, 2020) e a sua cadeia produtiva abrange mais de 8 milhões de empregos (Rank Brasil, 2014). Diante da representatividade desta cadeia nas atividades do agronegócio e na economia brasileira, torna-se necessário o aprimoramento de estratégias competitivas e de gestão em seus diferentes elos que possibilitem o desenvolvimento econômico, social e sustentável das suas atividades. Sendo assim, o objetivo com este artigo foi analisar a produção científica sobre a cadeia produtiva do café, na área de Administração no Brasil, a fim de identificar contribuições do ponto de vista de estratégia e gestão, além de lacunas de pesquisa. Para tanto, utilizou-se a revisão bibliométrica abrangendo o período de 2007 a 2019. Como resultados, foram identificados e analisados 116 trabalhos entre artigos, teses e dissertações com destaque para os principais temas estudados que são: boas práticas, gestão, consumo, internacionalização e estratégia, analisados sobre o enfoque de: mercado, região, consumidor e indústria. Conclui-se que esta revisão contribuiu para a mapear os temas estudados e esferas de análise, bem como para o avanço da discussão na perspectiva de gestão de diferentes elos da cadeia produtiva do café, com sugestões para uma agenda de pesquisa.
Multicultural Competence In School: Mental Health Providers In A Diverse Society
Authors: Giorgi Kelly
Published: January 2022

This paper explores the concept of multicultural competence as it relates to mental health professionals within the educational system. Brief definitions of prejudice, discrimination, and multicultural competence are put forth. Specifically, this paper describes the importance of cultural competency of school psychologists and their role in working with individuals and their families. As the United States grows into a more culturally diverse nation, it is imperative that school mental health professionals demonstrate multicultural competency across all areas of their work including assessment, consultation, counseling as well as understanding of laws and regulations in civil rights and education. This paper emphasizes on empirical evidence to describe the best practice training methods to be employed when developing training programs and producing the next generation of school psychologists. Keywords: Multiculturalism, Multicultural Competency, Counseling Competencies, Prejudice, Discrimination, Social Justice, School Psychologist
Repositioning Ghana Schools As English Language Learner Schools: Using Native And English Languages To Improve Academic Performance
Authors: Taylor Mark
Published: January 2022

This article argues that Ghanaian students’ academic performance might improve if instructors make use of their native languages and the English language (bilingual method) to provide instruction in school setting as it promotes classroom participation, engagement in learning, and the development of listening skills that improve comprehension. While there is some evidence to support this attitude, in fact, most young children do not speak English at home, and therefore, experience hardship in their learning. As a result, they are jeered and labeled as incompetent and incapable of being students. However, this article argues that students’ academic performance might improve if instructed in a bilingual setting as they will feel comfortable and confident about their learning in school. There is evidence that children underperform in school because educators abandon the traditional native languages at the onset of formal schooling in Ghana, and sometimes, the only language that students know best is their native language. Ghana’s official language is English; it applies to curriculum and instruction in public and private educational setting. The English language is vastly spoken in homes with middle income socio-economic status. With the rise of the middle class in the country, some citizens are abandoning the daily use of spoken vernacular and are speaking English at home as a rite of passage of giving their children a head start in their academic journey. English language learning approach can be useful to improve students’ English skills; however, if combined with their native language, it could effect change in education in Ghana. The English language teaching strategies must employ on content and language integrated learning, integrated content-based instruction, a focus on academic language proficiency, sheltered instruction, comprehensible input, learner-centered instruction, integrated skills approach, cooperative learning, and teacher collaboration (Calderón et al., 2015). This article employs meta-analysis of literature knowledge to advance professional practice in repositioning Ghana schools as English Language Learner Schools. Hence, English language proficiency for all students should be tasked with effective English language learning services in order to improve English language acquisition in Ghana.

Examining If Religion Influences Death Attitudes: Mental Health Perspective
Authors: Innocenti Jennifer , Scott Haley
Published: January 2022

Dying is inevitable; however, people respond to the concept of death differently. One’s response varies on his/her attitude towards religion and non-believers. There are five different death attitudes: (a) neutral acceptance which suggest that death is a part of life; (b) approach acceptance which holds a positive attitude towards death because one will have a happy afterlife; (c) escape acceptance wherein death is welcomed and seen as a way out for a life filled with pain, misery, and suffering; (d) fear of death is when a sense of fear is evoked by confrontations with death; (e) and death avoidance is when an individual avoids the topic of death in order to reduce death anxiety (Harding, Flannelly, Weaver, & Costa, 2005; Wong, 2008). While religious believers were able to forgive and found overall improved health; religion increased death anxiety as compared to non-believers. However, religion further helped with coping with the inevitable, death. Many studies found that there is a negative correlation between death anxiety and death acceptance. Despite religion helping one cope, it is also a source of stress for an individual facing death due to questioning their life choices and good deeds. This paper employs meta-analysis of seminal knowledge and statistical analysis to examine if religion influences death attitudes from mental health perspective. Keywords: Religion, Death Attitude, Death Anxiety, Death Fear, Mental Health Perspective
The Implementation Of Common Core Standards: The Abandonment Of Creativity And Critical Thinking
Authors: Stunder Stephen
Published: January 2022

This article explores a brief history of Common Core implementation as well as develops an argument for the return of critical and creative thinking in public school curriculum. The importance of student and teacher development in the delivery on instruction and student retention was also explored. In 2010, Common Core was established as a new educational standard of learning goals to help prepare students for college, career, and life. Common Core standards have changed the way in which the educational community views critical thinking. Upon its implementation, the Common Core looked to standardize the delivery of curriculum in public education. Nonetheless, these standards have minimized the ability for students to demonstrate and express critical thinking and creativity over the years. Policymakers have taken a shortcut in delivering opinions on curricular changes, and students’ abilities to think critically and creatively have suffered. Prior to 2010, states established their own standards for proficiency, which many believed led to a lack of standardization of curriculum. Currently, 42 of the 50 states have adopted Common Core standards. Virginia, Texas, Alaska, and Nebraska are four states that never implemented these standards, and Arizona, Oklahoma, Indiana, and South Carolina are four states that have withdrawn from the Common Core standards. This standardization of curriculum has led to difficulty in implementation and a lack of creativity at both the student and teacher level. Teacher development provides teachers with professional development on curriculum delivery and pedagogy as well as the opportunity for students to access their critical thinking skills. This article is a meta-analysis of literature knowledge to advance professional practice. Keywords: Common Core, Creativity, Critical Thinking, Curriculum, Design
The Importance of Inclusive Leadership Practice In Higher Education Administration
Authors: Quayson Felix
Published: January 2022

This paper aims to offer empirical evidence of the importance of inclusive leadership practice in higher education administration and the role educational professionals play in the academic setting to achieve institutional goals and vision. At a time when institutions are advocating with governmental agencies for funding and the graduate unemployment rate continues to be a challenge, it is critical for educational leaders, administrators, and professionals, alike, to be diverse and competent in inclusive practices in higher education. For instance, it is undesirable for an employee of any institution, whether staff, faculty (part-time and full-time), para personnel, student worker, consultant or other professionals within the campus environment to feel alienated in the governing process of institutional change. Inclusive leadership makes professionals feel a sense of belonging in the workplace thus contributing to the vision and goals of the workplace.

Skole-virksomhedssamarbejde i naturfagene: erfaringer fra et projektbaseret innovativt undervisningsforløb
Authors: Levinsen Henrik , Lindsay Thomas Stuart
Published: January 2022

This paper describes how a school-industry partnership can define and frame problem-based science teaching developed for lower secondary school. Among the identified positive outcomes was that students engaged in working with the authentic problems. Further, the student’s possibilities for building relations with the employees during the course was of central importance e.g. when they received feedback. Challenges reflected that the teachers and students were uncomfortable with the innovative problem-based teaching method and had a curricular-dominated view on science education. This was expressed in their concerns about what they see as indistinct connections between work phases and a lack of scientific content. It is proposed to use pedagogical link-making as a tool to create spatiotemporal coherence for the students and make connection between scientific concepts based on examples from the study. Link-making may be particularly relevant when the complexity of teaching increases as in school-industry partnerships.
Providing Professional Development for Physics Teachers through Participation in a Design-Based Research Project
Authors: Frågåt Thomas , Bøe Maria Vetleseter , Angell Carl
Published: January 2022

In this study, we examine professional development among twelve upper secondary physics teachers who participated in a design-based research (DBR) project. The teachers were involved in developing and testing learning materials in modern physics, and attended workshops and seminars with peers, disciplinary experts, and physics education researchers. Through a qualitative analysis of four focus group interviews, we found that the teachers had experienced professional development (PD) in content knowledge and pedagogical content knowledge (PCK), gained confidence, and discovered a need for more PD regarding assessment of qualitative competence. The teachers talked about content knowledge as the most important knowledge and skills to be a good physics teacher, but also valued knowledge about student thinking and misconceptions. Content knowledge was mentioned as a prerequisite for PCK. Our results show how involving physics teachers in a DBR-project stimulated professional development in several areas and uncovered needs for continuing PD.
