The Power Sources and Influences of Secondary School Principals in Eastern Ethiopia
Authors: Sintayehu Birhanu
Published: November 2020

This study aimed to critically examine the power sources and influences of school principals in secondary schools of Eastern Ethiopia. A descriptive survey research design was employed to carry out the study. The participants of the study were 145 teachers, 78 principals, and 41 supervisors who were selected by using stratified and random sampling techniques. The researcher adopted descriptive and inferential statistics to make sound interpretations of data. The results revealed that school principals were mostly used expert, legitimate, and reward sources of power. Likewise, school principals have predominantly exercised a positional basis of power rather than personal power. There was a significant statistical difference in power sources of school principals regarding positions, gender, and service years. The findings also showed that school principals dominantly practiced proactive influencing tactics. Moreover, findings indicated that subordinates carried out school principals' compliance to obtain a prize or avoid punishment by applied reactive influence tactics. The study further discovered that subordinates were inclined to resist school principals' influence. This study suggests secondary principals should rethink how power is managed and deployed to make sound influence over subordinates to assure quality education. Hence, the results of the study may serve as a springboard to improve secondary school leadership and equip novice teachers to bring them a principalship position. Plus, this study may provide a clear picture for policymakers, scholars, and government officials to support and retain principals for long-term school improvement, and it may also a theoretical benefit for future research on the area of study.

PERLINDUNGAN HUKUM TERHADAP KONSUMEN MUSLIM DARI PRODUK PANGAN YANG TIDAK BERLABEL HALAL DALAM PERSPEKTIF HUKUM POSITIF YANG TERKAIT DI INDONESIA DAN DI KOREA
Authors: ANGRIYANI ARI MARIYANA
Published: November 2020

Label halal merupakan bentuk tulisan pernyataan halal untuk menunjukkan bahwa produk yang dimaksud berstatus halal. Label halal berfungsi sebagai perlindungan konsumen agar hak kosumen muslim untuk mengkonsumsi produk halal terjamin. Indonesia sebagai negara dengan penduduk mayoritas Muslim sangat menjaga nilai halal suatu produk, terutama makanan. Belakangan ini banyaknya produk yang belum bersertifikat halal mengakibatkan konsumen muslim kesulitan untuk membedakan antara produk yang halal dan yang tidak halal untuk di konsumsi. Munculnya berbagai produk makanan asing dari berbagai negara telah menjadi hal yang lumrah bagi masyarakat. Namun, pada kenyataannya produk yang beredar di Indonesia tidak terjamin kehalalannya sehingga perlu pengawasan agar produk yang tidak halal, tidak dapat beredar dan dikonsumsi oleh masyarakat Muslim Indonesia. Tujuan penulisan jurnal ini untuk menjelaskan upaya perlindungan hukum terhadap konsumen muslim dari produk pangan yang tidak berlabel halal dalam perspektif hukum positif di Indonesia dan di Korea. Metode yang digunakan mengacu kepada peraturan perundang-undangan. Data yang diperoleh dianalisa dengan cara kualitatif. Berdasarkan hasil penelitian, regulasi yang berkaitan dengan produk Halal masih sangat minim. Oleh karena itu, dalam pengaturan perdagangan Korea disebutkan bahwa: “Acceptance of agency for commercial transactions”, yang berarti: Korea memberikan kebebasan kepada setiap agen untuk melakukan transaksi perdagangan termasuk dengan pemberian label halal pada produknya. Bentuk perlindungan konsumen bagi konsumen muslim adalah Sertifikasi halal.

Kata Kunci: Label halal, Konsumen Muslim, Perlindungan Konsumen.
Solving Shear-Wave Splitting in PS Data Processing of 3D 4C OBN Seismic Survey Offshore Nunukan, Indonesia
Authors: Waluyo A.
Published: November 2020

A 350-km2 3D 4C ocean-bottom node (OBN) offshore survey was acquired in December 2018, in Nunukan, North Kalimantan, Indonesia (Figure 1) with the processing work completed during 2019. Indonesia as a whole and the Nunukan survey area are situated in an active tectonic area where the Pacific Plate in the east and the Australian Plate in the south are actively pressing toward the Asian Plate. The tectonic activity is the main source of regional and local stress in the survey area. The dominant stress direction is Northeast-Southwest (NE-SW) (Figure 1). This stress exhibits azimuthal anisotropy in seismic waves, defined as the dependence of seismic wave speeds on propagation azimuth. In homogenous media, once the two horizontal geophone components of OBN acquisition have been properly rotated to the source-detector direction (radial) and a direction perpendicular to it (transverse), the converted waves (PS) energy will be maximum at the radial and minimum at the transverse directions. However, in azimuthal anisotropy media, shear waves split into fast and slow velocity components and the transverse data can appear to have more energy than the radial, as we observed clearly in the Nunukan OBN PS data. Ignoring the shear-wave splitting can result in degrading the PS seismic image. Herein, we outline how we addressed the azimuthal anisotropy in the Nunukan 3D OBN data. Without a shear-wave splitting correction, the PS seismic image lost data continuity of target horizons, making any attempt to correlate it with the PP image extremely difficult. The shear-wave splitting correction provided a much better PS image with improved structural data continuity and higher vertical resolution, giving greater confidence for PP-PS event correlation.

Effect of Fermentation on Antioxidant Activities and Betacyanin Content of Functional Beverages from Dragon Fruit and BeetrootKombucha is a traditional beverage prepared by fermenting polyphenol-rich tea using a consortium of bacteria and yeast (SCOBY). Dragon fruit and beetroot contain a significantly high amount of polyphenols and betacyanin as antioxidants which are beneficial in reducing the risk of cardiovascular disease, cancer, and the body's natural degeneration related to the early-aging process. This study aims to determine changes in antioxidant activity and levels of betacyanin from fermented dragon fruit and beetroot as functional drinks during different fermentation times. The results showed that there was a correlation between fermentation time and antioxidant activity in its ability to counteract free radicals, ferric reducing antioxidant power (FRAP), and the levels of betacyanin produced. Longer fermentation time caused an increase in free radical inhibition and reduction of iron ions but reduced the levels of betacyanin. The optimum value of free radical inhibitory activity (DPPH) was obtained in the 12-day fermented dragon fruit drink with an inhibitory value of 80.76%, ability to reduce iron ions by 197.94 Âµg ascorbic acid mL-1, and betacyanin level of 0.055 mg L-1Keywords: antioxidants, dragon fruit, betacyanin, beetroot, functional beveragesÂ ABSTRAKKombucha merupakan minuman tradisional hasil olahan fermentasi teh yang kaya polifenol dengan konsorsium bakteri dan yeast (SCOBY).

Published: November 2020

Most of the soils suffered from significant geotechnical problems dependent on factors like the type of soil, soil composition and mineralogy. Specifically, the problems related to mechanical and physical properties of soils. Several studies have been used to mitigate the adverse effects of soils through using either additive conventional materials such as cement, lime or these soils blending with produced material and chemical materials. This paper focuses on stabilizing or improving different soils using sustainable materials. These materials provided environmental and economic benefits while mitigating a health hazard, storage problems, and a potential pollution source. They can be classified according to these sources into four groups: industrial waste (by-products), agriculture waste, domestic waste and mineral waste. According to the results of this review, compaction characteristics, California bearing ratio and unconfined compressive strength have been studied and discussed in this paper.
Strut and Tie Modelling of Reinforced Concrete Deep Beams Under Static and Fixed Pulsating Loading
Authors: Quadri Ajibola Ibrahim
Published: November 2020

Numerical analysis of the performance of reinforced concrete (RC) deep beam subjected to static and fixed-point pulsating loading at the midpoint has been investigated. Three-dimensional nonlinear finite element model using the Strut and Tie approach was adopted. The damage level under the influence of the applied fixed pulsating loading is higher than the static applied loading, hence early crack was observed because of the stepwise loading in the form of vibration. Although the Strut and Tie approach gave a good estimation of the resistance capacity of the beam, the beam undergo high shear damage when subjected to these two types of loading. Material strength properties, applied loadings and cross-sections adopted are some of the factors that affect the performance of the deep beam.

Authors: Matta Anil K. , Koka Naga S. S. , Devarakonda Sameer K.
Published: November 2020

Magnesium Metal Matrix Composites (Mg MMC) have been the focus of consideration by many researchers for the past few years. Many applications of Mg MMCs were evolved in less span of time in the automotive and aerospace sector to capture the benefit of high strength to weight ratio along with improved corrosion resistance. However, the performance of these materials in critical conditions is significantly influenced by several factors including the fabrication methods used for processing the composites. Most of the papers addressed all the manufacturing strategies of Mg MMC but no paper was recognized as a dedicated source for magnesium composites prepared through stir casting process. Since stir casting is the least expensive and most common process in the preparation of composites, this paper reviews particulate based Mg MMCs fabricated with stir casting technology. AZ91 series alloys are considered as the matrix material while the effect of different particle reinforcements, sizes , weight fractions on mechanical and tribological responses are elaborated in support with micro structural examinations. Technical difficulties and latest innovations happened during the last decade in making Mg MMCs as high performance material are also presented.
Thermal - electrical analogy in dynamic simulations of buildings: Comparison of four numerical solution methods
Authors: Michalak Piotr
Published: November 2020

The lumped capacitance method is widely used in dynamic modelling of buildings. Models differ in complexity, solution methods and ability to simulate transient behaviour of described objects. The paper presents a mathematical description of a simple 1R1C thermal network model of a building zone. Four numerical methods were applied to solve differential equation describing its dynamics. For validation purposes two test cases (600 and 900) from the BESTEST procedure were used. In both cases detailed results were given. Better ability of the simulation model to reproduce transient behaviour of the modelled buildings was noticed in case of the lightweight object (case 600). Annual heating and cooling demand was within the reference range for heavyweight one (case 900). The kind of the computation method had no significant effect on simulation results.

The review deals with microwave antennas, devices (including reflectors), materials and media with nonreciprocal properties, which, due to their uniqueness and promising application, have become the topic of a large number of scientific studies and publications. It is noted that amplitude nonreciprocity can be realized not only with the help of magnetized ferrites and semiconductor amplifiers, but also based on parametric and nonlinear structures using space-time modulation. Therefore, polarization nonreciprocity can also be achieved on magnet-free components, including varactors, and other parametric elements. When analyzing reciprocal reflectors made both on "thin" surface structures and on bulk waveguides, it is appropriate to consider reciprocal cross-polarizing (depolarizing) "invisible"-reflectors, converting the initial polarization of the incident wave into the orthogonal polarization of the reflected wave, which can be built with using only reciprocal passive components without the use of non-reciprocal ones (ferrite circulators, gyrators, etc.). The combination of polarization and nonreciprocal properties in radar reflectors, RFID tags, etc., is an additional degree of freedom in the design of new generation electronic systems.

The hematoophthalmic barrier is one of the mechanisms of resistance that serves to protect the body and prevents homeostasis disorder when the body is affected by factors that can disturb this balance. One of the complications of mechanical trauma of the eye and violation of the hematoophthalmic barrier is the appearance of oxidative stress on the background of the general inflammatory process in violation of cellular structures. Objective: to study the dynamics of catalase activity in the heart and muscle tissue of rats under oxidative stress caused by mechanical action on the hematoophthalmic barrier. Materials and methods. The study was carried out on white neonatal mature healthy male rats of six months of age, weighing 200–220 g and having 150 pieces. The activity of catalase in heart and muscle tissue was studied before the beginning of the experiment, as well as on the 1st, 3rd, 5th, 7th and 14th day of the experiment using the standard Korolyuk M.A. method. The dynamics of catalase activity was evaluated by different methods of treatment of mechanical eye trauma, including the use of quercetin antioxidant. The results of the study. It was found that in addition to the standard therapy of mechanical eye injury injection of quercetin, the activity of catalase in the heart and muscular tissue after falling on the background of induced oxidative stress increases to the values of physiological norm by 14 days, which indicates the effective elimination of oxidative stress. Conclusions. The activity of catalase in rat heart and muscle tissue under oxidative stress caused by mechanical influence on hematoophthalmic barrier is most effectively stabilized under standard therapy of mechanical eye injury with addition of quercetin in the form of injections.

Purpose. Revealing the dependence of the formation of high yield and quality indicators of winter seeds on the influence of the level of intensification of the cultivation technology in the conditions of the Forest-Steppe of the Right Bank. Methods The results of the conducted researches on the influence of the sowing method, sowing norms of winter rape on its seed productivity are given. The prospect of expanding the sown areas of winter oilseed rape, actualizes research to identify the dependence of the formation of high yields and quality indicators of winter oilseed rape from the influence of the level of intensification of cultivation technology. The research methods used in the field experiment correspond to the methods of field experiments and guidelines. The experiment was established by the method of split sites. Winter rapeseed cultivar Antaria of Ukrainian selection and Exagon hybrid of foreign selection were used for sowing. The generally accepted technology of growing winter rape for the area where the research was conducted was used. Results. The results of the research on the influence of sowing method, sowing norms of winter oilseed rape on its seed productivity show that the highest yield of winter oilseed rape seeds was obtained by sowing ordinary row with a row spacing of 15 cm, and sowing rate in the variety - 0.8 million seeds /ha, hybrid - 0.6 million seeds / ha. It is established that the method of sowing and sowing norms affect the quality of winter rape. The optimal sowing rate of winter rapeseed is for the variety - 0.8 million similar seeds per 1 ha, for the hybrid - 0.6 million similar seeds per 1 ha, when sown in the usual row method with a row spacing of 15 cm. Conclusions. It was found that the highest oil content in winter rapeseed was - 46.98% for sowing in a wide row with a row spacing of 45 cm. Also, this method of sowing was determined by the lowest (0.39%) content of erucic acid, while the content of glucosinolates for this method of sowing was higher (33.1 μmol / g) compared to the usual method of sowing.
Comparison of Digital Applications and Conventional Equipment in Group and Individual Recreational Activities: Social Psychology, Social Interactions, Emotional Reaction, and Perceived Usability in Middle-aged and Senior Citizens
Authors: Fang Yu-Min
Published: November 2020

In an aging society,
improving quality of life for middle-aged and senior citizens is crucial. In
Taiwan, karaoke recreation is a popular event among senior citizens. This study
examined the effects of singing on middle-aged and senior citizens via testing
such individuals before and after singing. The tested aspects consisted of
social psychology, social interaction, emotional reaction, and usability. The
experiment design categorized karaoke events into “group singing” and
“individual singing.” The tested karaoke equipment consisted of conventional
physical karaoke equipment (hereafter referred to as conventional karaoke
equipment) and new karaoke software applications. Experiment participants
comprised 48 middle-aged and senior citizens from Miaoli, Taiwan, who were
divided into three groups, namely individual participant using digital
application, individual participant using conventional karaoke equipment, and
grouped participants using conventional karaoke equipment. Results revealed
that after singing, the participants’ social avoidance and distress levels
decreased, their emotions improved and strengthened, and, and they demonstrated
enhanced social interaction behaviors. Furthermore, group singing yielded
greater effects than individual singing did, whereas the effects were greater
among participants who used conventional karaoke equipment than those who used
digital applications. Participants who used conventional karaoke equipment
demonstrated enhanced emotions, social interactions, and satisfaction with
usability. Despite attempts to enhance competitiveness via integrating online
social functions, new karaoke software still has space for improvement.
Employee Engagement as Motivation: Implications for HRM theory, methods, and practice
Authors: Pincus Jeremy
Published: November 2020

Perhaps the central theoretical construct in human resource management today is employee engagement. Despite its centrality, clear theoretical and operational definitions are few and far between, with most treatments failing to separate causes from effects, psychological variables from organizational variables, and internal from external mechanisms. This paper argues for a more sophisticated approach to the engagement concept, grounding it in the vast psychological literature on human motivation. Herein lies the contribution of our paper; we argue that the apparent diversity of operational definitions employed by academics and practitioners can be understood as tentative attempts to draw ever nearer to key motivational concepts, but never quite get there. We review the leading definitions of employee engagement in the literature and find that they are reducible to a core set of human motives, each backed by full literatures of their own, which populate a comprehensive model of twelve human motivations. We propose that there is substantial value in adopting a comprehensive motivational taxonomy over current atheoretical approaches, which have the effect of “snowballing” ever more constructs adopted from a variety of fields and theoretical traditions. We consider the impact of rooting engagement concepts in existing motivational construct for each of the following: (a) theory, especially the development of engagement systems; (b) methods, including the value of applying a comprehensive, structural approach; and (c) practice, where we emphasize the practical advantages of clear operational definitions.

The framework of Islamic law is clearly described in the rule of maqasid al-syariah in the form of legislation to accommodate the situation and conditions. Further study in the Quran and hadith discovered that Islam has specific principals and rules that demand environmental maintenance. This research aims to reveal the direction and regulations of environmental management comprehensively according to Islamic law using the philosophical, phenomenology, and normative approaches. Some important principles of environmental ethics in Islam are portrayed in the examples that appear to develop new Islamic thinking in environmental ethics. Due to the common future and possibilities as well as the threats with the same bad results, all self-correction process requires feedback from an Islamic perspective on environmental maintenance. Due to the global impact of the environmental crisis, cooperation from all parties is required to prevent the unnecessary pose of environmental hazards, and existing environmental hazards must be best avoided. This research shows how the Islamic principles on environmental ethics work as a mechanism to bring normative change and review the human diagnostic capacity to evaluate different use of natural resources, including the ethics of environmental maintenance.

The neural basis of multitasking
Authors: Garner Kelly , Dux Paul Edmund
Published: November 2020

As humans, we show striking adaptability in our behavioural repertoires. Despite this apparent ability to adapt and assimilate a large variety of behaviours to suit our current contexts, we show some striking limitations in how many tasks we can perform at any given moment. Although some behaviours can appear to be performed concurrently with ease, such as talking while walking, we show a stark inability to combine other tasks and skills; imagine compiling a grocery list while recalling your partner’s phone number. The observation that attempting to perform multiple tasks concurrently results in at least one of those tasks being performed more slowly, and with less accuracy, was among the first to be made when cognitive psychology was emerging as a scientific discipline (Telford 1931; Welford 1959). Interestingly, among these early observations, it was also noted that such performance costs can to some extent be reduced with practice (Telford 1931), suggesting malleability in how tasks are performed that carries consequences for multitasking operations. Since then, efforts have been made into understanding the nature of the putative operations that give rise to multitasking costs, the neural computations and architectures that instantiate those operations, and the neural and functional changes that drive improvements in multitasking performance. The aim of this chapter is to synthesise the in-roads that have been made into understanding the neural basis of multitasking costs and their practice-induced remediation, and to use that knowledge to propose the next steps forward in our understanding.
Validation to Spanish version of the COVID-19 Stress Scale
Authors: Pulido Edgar Guillermo , JIMENEZ LUZ
Published: November 2020

There is a global consensus about the potential of the COVID-19 pandemic to affect people's mental health. In this context, and prior to the formulation of mitigation strategies, tools are required that allow an objective and effective assessment of mental health risk. The purpose of this study was to evaluate the psychometric characteristics of COVID-19 Stress Scale, formulated by Taylor et al. (2020), based on the concept of COVID-19 Stress Syndrome. A national sample of 1214 participating adults was taken in Colombia, who answered a translated version of the scale. Evidence of a hexa-dimensional structure was obtained whose goodness of fit indicators were Chi2 = 1215,759, Sig. =. 000, CMIN / DF = 2.202, RMSEA = .044, NFI = .943, TLI = .964, CFI =. 968 and FMIN = 1,967. Regarding reliability, an α = .924 and Spearman-Brown = .824 were obtained for the entire scale; the reliability indicators of the 6 subscales were also high. The similarities and differences in the findings with respect to the original psychometric study of the scale are discussed, as well as the utility and importance of the instrument as a tool in future efforts to mitigate the psychosocial effects of the pandemic
Inhibition of return: An information processing theory of its natures and significance
Authors: Redden Ralph S. , MacInnes Joseph , Klein Raymond M
Published: November 2020

Inhibition of return (IOR) is an inhibitory aftereffect of visuospatial orienting, typically resulting in slower responses to targets presented in an area that has been recently attended. Since its discovery, myriad research has sought to explain the causes and effects underlying this phenomenon. Here, we briefly summarize the history of the phenomenon, and describe the early work supporting the functional significance of IOR as a foraging facilitator. We then shine a light on the discordance in the literature with respect to mechanism—in particular the lack of theoretical constructs that can consistently explain innumerable dissociations. We then describe three diagnostics (central arrow targets, locus of slack logic and the Psychological Refractory Period, and performance in speed-accuracy space) used to support our theory that there are two forms of inhibition of return—the form which is manifest being contingent upon the activation state of the reflexive oculomotor system. The input form, which operates to decrease the salience of inputs, is generated when the reflexive oculomotor system is suppressed; the output form, which operates to bias responding, is generated when the reflexive oculomotor system is not suppressed, Then, we subjected a published data set, wherein inhibitory effects had been generated while the reflexive oculomotor system was either active or suppressed, to diffusion modelling. As we hypothesized, based on the aforementioned theory, the effects of the two forms of IOR were best accounted for by different drift diffusion parameters. The paper ends with a variety of suggestions for further research.
Badania aspektu w językach polskim, czeskim i rosyjskim za pomocą korpusów i baz danych (pierwsze podsumowanie tematu)
Authors: Wiemer Björn , Wrzesień-Kwiatkowska Joanna , Łaziński Marek
Published: November 2020

The article is connected to the project “DiAsPol250” in which Polish is compared to Czech and Russian from the perspective of the evolution of their aspect systems (http://www.diaspol.uw.edu.pl/). We make use of existing synchronic and diachronic electronic corpora and are building a corpus of our own with annotated aspect pairs; we also create a database of aspect triplets whose role we consider as particularly important for the system. We want to assess which changes have occurred since the mid-18th century in prefixing and suffixing strategies of verb stems, both in general and by comparing particular prefixes and suffixes, especially so-called natural (vs. specialized) prefixes (according to Janda et al., 2013). The article supplies a sketch of the general premises of the project, and it summarizes our experience with existing large corpora and databases which we have been employing. We also present a case study in order to demonstrate a procedure designed to compare the distribution of the Czech prefix z- in triplets and in the corpus. This procedure is meant to check more general tendencies; it also illustrates why electronic corpora cannot be replaced in research on distributional properties and why their role does not consist simply in providing examples for the illustration of hypotheses.
Projektowanie metadanych w korpusie tekstów polskich do 1500 roku – wielopoziomowa struktura informacji
Authors: Leńczuk Mariusz
Published: November 2020

The subject of research are selected metadata that should characterize the texts collected in the corpus of the oldest attestations of the Polish language. The author of the article compares and analyses the factors affecting the development of the basic data structure used in synchronic and diachronic corpora (author, title, date of the text, text channel, text classification, source of citation). Without those factors taken into account the disambiguation of the object in the database becomes impossible, and the use of grammatical information is unreliable and impractical. The result of the presented analysis is a proposal to extend the level of description for individual markers.
Mystik och polemik
Authors: Nenzén Niklas
Published: November 2020

In recent studies of Western esotericism, the essentialist status and “religionist” design of the concept of gnosis has been disputed. Current aspects of the concept to discuss are gnosis as modern construction, as reflective surface of a secular worldview, and as an element in revisionary historiographies. This article explores the dynamic of tradition and renewal of the concept of gnosis, employing as a case study the Lectorium Rosicrucianum, an international Rosicrucian New Religious Movement that so far has received little academic attention. My methodological procedure is a Weberian analysis of the LR:s application of the concept of gnosis in legitimation strategies and in blending charismatic appeal with claims of traditional authority. I argue that while a construct of LR as ideological “Gnostic dualists” can be derived from their polemical discourse, their outlook of “dynamic dualism”, drawing on alchemy and German mysticism, retains gnosis as both an ineffable, mytho-poetically circumscribed experience and as social and corporeal phenomena.

Obrazovatel'naya i kadrovaya politika tsarizma v Belarusi v 1860-ye gg.
Authors: Ostroga Walentina
Published: November 2020

The article notes that the duality, inconsistency, and reactionarity of the educational policy of the tsarist government after the uprising of 1863–1864 was largely dictated by the desire to reduce Polish influence and accelerate the russification of the region. The Ministry of Public Education did not care so much about the dissemination of education as about protecting the public with “reasonable restrictions”. In accordance with its political and ideological goals, the network of parish schools expanded, the training of teaching staff was restrained, and strict control was established over the activities of teachers and their political trustworthiness. Tsarism formed a model of an “ideal” teacher: devoted to the church and the throne, tolerant, imperceptible, and obedient, who in his pedagogical activity was to follow the official course. There was a tendency to attract people from the central provinces of Russia who graduated from theological seminaries, as well as Orthodox priests, to fulfill teaching duties.
