Authors: Apriani Nabilah , Said Ridwan Wijayanto
Published: March 2022

UMKM memiliki peran sentral dalam perekonomian nasional, namun pemerintah lebih banyak memberi kontribusi dan perhatian penuh kepada usaha besar. Sehingga hal tersebut menyebabkan di butuhkannya perlindungan Hukum terhadap UMKM. Penelitian ini berfokus pada pembahasan mengenai Bagaimana upaya perlindungan hukum Terhadap Industri Usaha Mikro Kecil dan Menengah (UMKM) di Indonesia serta Bagaimana konsep perlindungan UMKM berdasarkan pendekatan keadilan ekonomi. Metode penelitian yang digunakan dalam penelitian ini adalah metode penelitian hukum normatif empiris, dengan spesifikasi penelitian deskriptif analitis untuk selanjutnya dilakukan pengumpulan data dengan cara studi pustaka yang bersumber pada bahan hukum primer, sekunder dan tersier untuk selanjutnya di analisis secara kualitatatif. Hasil Penelitian ini menunjukan bahwa UMKM sebagai suatu industri berskala kecil masih menganggap bahwa perlindungan kekayaan intelektual bukanlah suatu hal yang penting. Sehingga diperoleh kesimpulan bahwa Perlindungan merek terhadap pelaku usaha UMKM tidak hanya sebagai perlindungan negara terhadap pemilik merek terdaftar tetapi juga bentuk perlindungan terhadap masyarakat selaku konsumen sehingga Hukum harus difungsikan untuk mengubah dan memihak (afirmatif action) kepada usaha kecil agar lebih berdaya dan tetap eksis dalam menjalankan usahanya bersama dengan usaha besar.

Published: March 2022

Aim. To compare the best mulberry collection accessions by resistance to diseases (cylindrosporium leaf spot, bacteriosis and wilt) and infructescence yield as well as adaptation to climatic conditions in Northeastern Ukraine.
Results and Discussion. The collection of the mulberry gene pool of the Laboratory of Sericulture and Technical Entomology of the National Research Center "Institute of Experimental and Clinical Veterinary Medicine" of NAAS, which comprises 104 accessions, was studied. The article presents the results of studying features of the most promising fruit varieties of mulberry bred in Ukraine and introduced from different countries. The study showed that the Ukrainian mulberry fruit varieties from the gene pool collection were resistant to cylindrosporium leaf spot, bacteriosis and wilt. The introduced fruit varieties were weakly affected by cylindrosporium (8.0%) and bacteria (3.7%); varieties Bulgaria 24 and Kimsan were resistant to bacteriosis. Varieties Ukrainskaya 5, Ukrainskaya 6, Ukrainskaya 7, Ukrainskaya 107, Nadezhda, Kharkovskaya 14, Plodovaya 1, Yuzhnaya 6, Kimsan, Jasan, Kokuso 21, Kokuso 25, and Shimo maru were wilt-resistant. Mulberry plants of these varieties are adapted to climatic conditions of Northeastern Ukraine. The study showed that varieties Ukrainskaya 5, Ukrainskaya 6, Ukrainskaya 7, Nadezhda, Kharkovskaya 14, Kimsan, Jasan, Kokuso 21, and Shimo maru were valuable as donors of resistance to cylindrosporium leaf spot, bacteriosis and wilt. Varieties Ukrainskaya 6, Ukrainskaya 7, Ukrainskaya 107, Nadezhda, Kharkovskaya 14, Plodovaya 1, Plodovaya 3, Yuzhnaya 6, Podkumskaya, Ussuriyskaya 24, Bulgaria 59, Kimsan, Jasan, Kokuso 25, and Shimo maru consistently gave high yields of infructescences with high-quality fruits. Over the last 5 years, surveys of these mulberry varieties demonstrated that winterkill of shoots in the experimental location did not exceed 5.0%.
Conclusions. Analysis of the results of studying the fruit varieties of Ukrainian and introduced mulberry from the collection of the Sericulture Laboratory showed that varieties Ukrainskaya 5, Ukrainskaya 6, Ukrainskaya 7, Nadezhda, Kharkovskaya 14, Kimsan, Jasan, Kokuso 2, and Shimo maru could be used as donors of resistance to cylindrosporium leaf spot, bacteriosis and wilt. Varieties Ukrainskaya 6, Ukrainskaya 7, Ukrainskaya 107, Nadezhda, Kharkovskaya 14, Plodovaya 1, Plodovaya 3, Yuzhnaya 6, Podkumskaya, Ussuriyskaya 24, Bulgaria 59, Kimsan, Jasan, and Shimo maru were highly adapted to the climate of Ukraine and gave stable and high yields of infructescences.
UV Radiation, not European Ancestry, Explains States’ Cognitive Performance in Brazil and USA
Authors: R. León Federico , Antonelli-Ponti Mayra , Burga-León Andrés
Published: March 2022

A debate in Mankind Quarterly positing racial categorization of populations vis-à-vis biological effects of UV radiation was based on data from a single country, used absolute latitude instead of UV radiation, and limited the analysis to path analysis. To overcome limitations of the studies, we utilized measurements of UV radiation for 26 Brazilian and 48 USA states instead of absolute latitude and performed seemingly unrelated regressions in addition to path analysis. NAEP scores and infectious disease rate were collected in USA and PISA scores and infant mortality in Brazil. Significant cognitive effects of European ancestry were replicated, but showed spuriousness, disappearing when the effects of UV radiation were controlled. Our evidence strongly suggests that UV radiation is a consistent antecedent of cognitive ability directly and through income in the USA and Brazil and through infant mortality in Brazil, whereas European ancestry only influences cognitive ability positively by reducing infectious diseases in the USA or infant mortality in Brazil. The between-country consistency of our findings compensates for methodological weaknesses that took place especially in the Brazil study. Psychologists and economists should be aware of these findings to avoid making erroneous inferences based on genetic or cultural variables.

Authors: Wekesa Violet , Kitainge Kisilu
Published: March 2022

The performance of upgraded extra county schools to national status in Kenya continues to attract key stakeholders when the time the KCSE results are being announced. This is because despite their upgrading, the performance of these upgraded new schools continues to worry stakeholders. This paper investigates how the planning for instructional resources influences academic performance. A descriptive survey research design was used with the target population consisting of 8 principals and 295 teachers from 8 upgraded extra county schools to national status in Western Kenya. A sample of 170 teachers was selected through simple random technique to be involved in the study. The instruments used to collect data consisted of questionnaire and interview schedule. Data analysis has been performed using quantitative and qualitative forms. Quantitative analysis of data has been facilitated by use of descriptive and inferential statistics with the help of Statistical Product and Service Solutions (SPSS Version 25.0). The study found that aside many instructional materials required in schools, only text-books for students were supplied in adequate quantity. However, learning resources for teachers (including reference books) were not adequately provided to these schools. In line with the government agenda of promoting ICT knowledge, the study discovered that ICT resources like computers were not adequately provided after the Extra County Schools in the region were upgraded to national status in Western Kenya. Correlation statistics showed that there existed no significant relationship (p>0.05) between instructional material planning dynamics and performance of Extra County Schools after they were upgraded in Western Kenya. The paper recommends that there is need for schools to consider adoption of new instructional media in teaching and learning.

Dekorative und effektive Optimierung der Raumakustik im Bestand
Authors: Friedl Wolfgang
Published: March 2022

Wer erinnert sich nicht an Eierkartons in Bandproberäumen als Schallabsorber? Oder an dunkle Noppenschaumstoffplatten? Die Ansprüche an Schalldämpfungsmaßnahmen sind über die Jahre kontinuierlich gestiegen. Bei der Neuplanung von Räumen wird heutzutage von Architekten ein Bauphysiker oder Raumakustiker als Fachplaner hinzugezogen, um schon im Vorfeld eine gute Raumakustik zu berücksichtigen. Aber auch im Bestand werden die Ansprüche an eine gute Raumakustik immer höher. So sind häufig Lösungen gefragt, die auf der einen Seite akustisch wirksam sind, auf der anderen Seite auch den gestiegenen optischen Ansprüchen Rechnung tragen. Anhand von mehreren Praxisbeispielen sollen hier passende Lösungsansätze dargestellt werden.
Implicit expectation modulates multisensory perception
Authors: Zeljko Mick , Grove Philip M. , Kritikos Ada
Published: March 2022

Stimulus statistics can induce expectations that in turn can influence multisensory perception. In three experiments, we manipulate perceptual history by biasing stimulus statistics and examined the effect of implicit expectations on the perceptual resolution of a bistable visual stimulus that is modulated by sound. First, we found a general effect of expectation such that responses were biased in line with the biased statistics and interpret this as a bias towards an implicitly expected outcome. Second, expectation did not influence the perception of all types of stimuli. In both Experiment 1 and Experiment 2, integrated audio-visual stimuli were affected by expectation but visual-only and unintegrated audio-visual stimuli were not. In Experiment 3 we examined the sensory versus interpretational effects of expectation and found that contrary to our predictions, an expectation of audio-visually integrated stimuli was associated with impaired multisensory integration compared to visual-only or unintegrated audio-visual stimuli. Our findings suggest that perceptual experience implicitly creates expectations that influence multisensory perception, which appear to be about perceptual outcomes rather than sensory stimuli. Finally, in the case of resolving perceptual ambiguity, the expectation effect is an effect on cognitive rather than sensory processes.

Algunas consideraciones acerca de la justificación de los principios de la justicia en A Theory of Justice
Authors: Loewe Daniel
Published: March 2022

En A Theory of Justice, Rawls articula una teoría contractualista de justicia. El artículo indaga en la metodología justificativa de los principios de justicia que caracterizan su concepción de justicia como equidad (fairness). Esta metodología recurre a dos mecanismos distintos: la posición original y el equilibrio reflexivo. El artículo sostiene que el primer mecanismo se retrotrae al segundo, y que ambos mecanismos expresan el carácter contractualista específico de la teoría rawlsiana, como una que refiere tanto al interés propio como a la imparcialidad.

Authors: Bak Iwona , Ziolo Magdalena , Cheba Katarzyna , Spoz Anna
Published: March 2022

The aim of the article is to study ESG factors and the motives of including the ESG perspective by companies in their business models (BM). The 2-stage research procedure was used to analyse the problem: bibliographic research was carried out with the use of VOSviewer software. In the paper, 99 from 3000 publications were selected for in-depth analyses, and various types of correlation measures were selected, examining the strength and direction of the relationship between the variables included in two-way and multi-way frequency tables. Fourteen binary variables were constructed with two categories, “yes” and “no”, which were assigned ranks 1 and 0, respectively. It turned out that there is a moderate (0.379) significant correlation between ESG factors and companies’ business models. The environmental factor is most often emphasized in these models (0.308). In the SME sector, CSR (1.000 – full correlation) and ESG factors (0.471) are taken into account, with the strongest relationships between this sector and Government (0.615) and Social (0.549). The role of the financial market in supporting sustainability in companies’ business models is growing and taking on importance.
Decaisnina tomentosa (Loranthaceae), a new species of mistletoe from Samar Island, Philippines
Authors: Tandang Danilo , delos Angeles Marjorie , Buot Inocencio, Jr. , Devkota Mohan Prasad , Caraballo-Ortiz Marcos
Published: March 2022

The extensive forests over limestone of the Samar Island Natural Park (SINP) on Samar Island, Philippines harbour a rich variety of unique species. In this contribution, we describe and illustrate a new Loranthaceous mistletoe, endemic to Samar Island named Decaisnina tomentosa, representing the 12th member of the genus reported to the Philippines.

This new species is similar to D. confertiflora (Merr.) Barlow with respect to the presence of shortly and densely off-white tomentose inflorescence and 6-merous flowers. However, it is unique amongst congeners in having tomentose and partially fused bracteoles which cover almost or entirely the ovary of individual flowers in the triads. To date, D. tomentosa seems to be restricted to the SINP and is only known from a handful of individuals. More studies are needed to properly assess the demography, host range, conservation status and phylogenetic position of this distinctive species of mistletoe.
Correlation between cognitive abilities and social functioning in patients with multiple sclerosis
Authors: Genov Krasimir , Dimitrova Maria
Published: March 2022

Introduction: Cognitive impairment has been found in all stages and subtypes of multiple sclerosis (MS). It has a broad negative impact on the lives of people with MS independent of physical symptoms. Perhaps the most severe and far-reaching effect is unemployment, which results in extensive personal, social, and financial costs. Cognition has been linked to unemployment in many countries and shown to mediate the effects of disability on employment status.

Aim: The primary aim of this study was to assess social functioning in the context of activities of daily living and employment in patients with MS and to find a correlation between them and cognitive performance in these patients. The secondary aim was to find an association between employment and factors such as demography, emotional factors, and disease progression. 

Materials and methods: The research included a study group of 100 patients with MS meeting the defined exclusion and inclusion criteria, and a control group of 40 healthy subjects. Disability was assessed with the Expanded Disability Status Scale (EDSS). The employment status was appraised in interviews with the subjects. The patients were divided into two groups: employed (working on a full-time or part-time job) and unemployed (not-working). The study aimed to assess the cognitive performance of all subjects. We examined cognitive domains such as short-term memory, psychomotor speed, and executive functions with a battery of neuropsychological tests.

Results: We found a connection between performance on neuropsychological tests and employment and engagement in activities of daily living. Another main conclusion of our study is that unemployed are older patients with longer duration of disease. They have excessive fatigue and unsatisfied results and impairment of memory functions. As to the reasons we found in our study for losing a job, some identified factors are the presence of excessive fatigue (44%), movement disorders (41%), cognitive impairment (30%), pain (15%), dizziness (15%), dexterity (11%), emotional disorders, bowel and bladder disorders (7%), visual deficit (7%), and heat sensitivity (4%).

Conclusions: Unemployed patients have severe depressive symptoms.

Aim: Infantile hemangiomas are the most common benign vascular tumours in infants. In this study, we aimed to evaluate the effectiveness of propranolol therapy in patients with infantile hemangioma.

Materials and methods: This study included patients with infantile hemangiomas in the age range of 0 to 24 months who received propranolol therapy between September 2015 and 2019. Hemangioma activity score, ultrasonography imaging and photographic evaluations were performed before and at 6 months of treatment. Parental satisfaction with the results of treatment was recorded.

Results: Our study included 85 patients with infantile hemangioma requiring treatment. Twenty patients were boys and 65 were girls. The mean age at starting treatment was 7.2±5.9 months (median: 5.0). While the average lesion area measured by ultrasonography before treatment was 209.7±207.5 mm2, it reduced to 105.1±145.7 mm2 (p<0.001) after treatment. Similarly, while the mean hemangioma activity score was 3.8±0.9 before treatment, it decreased significantly to 1.3±0.8 after the treatment (p<0.001). A noticeable improvement in photographic evaluation with the treatment was observed in infantile hemangiomas of the patients and 82% of the families were satisfied with the results of the treatment.

Conclusions: The results of the study suggested that propranolol therapy used in the treatment of infantile hemangioma is an effective treatment option according to the photographic comparison, ultrasonography data, and hemangioma activity score evaluations.

Published: March 2022

Introduction: Circadian variations in biological rhythms affect the pharmacological properties of many anaesthetic agents, suggesting circadian patterns of local anaesthetics’ activity in labour pain analgesia, with important differences among diurnal and nocturnal phases.

Aim: We examined whether a rhythmic variation of the effect of intrathecal mixture of levobupivacaine and fentanyl exists throughout the day period regarding caesarean sections. 

Materials and methods: Eighty parturients presented for caesarean section, both urgent and/or elective, were assigned to five equal groups (A, B, C, D, and E) according to the time-point of the intrathecal drug administration. The same levobupivacaine and fentanyl dose was given to all patients. Pinprick or cold test, the four-point modified Bromage scale (0-3), and the numerical scale (NRS 0-10) were used respectively for the assessment of sensory and motor blockade, and post-anaesthetic pain. The duration of sensory and motor blockade, analgesia duration and pain score at first analgesic request were recorded.

Results: Statistically significant differences were found among the studied groups in the duration of motor and sensory blockade and pain score at first postoperative analgesic request. Prolonged duration of motor blockade in groups A, B and C (p<0.001) and prolonged duration of sensory blockade and analgesia in groups A, B (p<0.001) were observed. Higher pain scores at first postoperative analgesic request were recorded in group Ε (p<0.001). 

Conclusions: The present study highlights the significant effects of circadian rhythm on the efficacy of a mixture of local anaesthetics, levobupivacaine and fentanyl, during caesarean delivery.
Multiple solutions for the fourth-order Kirchhoff type problems in $ \mathbb{R}^N $ involving concave-convex nonlinearities

In this paper, we study the multiplicity of solutions for the following fourth-order Kirchhoff type problem involving concave-convex nonlinearities and indefinite weight function

   \begin{document}$ \begin{equation*} \Delta^2u-\left(a+b\int_{ \mathbb{R}^N}|\nabla u|^2dx\right)\Delta u+V(x)u = \lambda f(x)|u|^{q-2}u+|u|^{p-2}u, \end{equation*} $\end{document}

where $ u\in H^2(\mathbb{R}^N)(4 < N < 8) $, $ \lambda > 0, 1 < q < 2, 4 < p < 2_\ast(2_\ast = 2N/(N-4)) $, $ f(x) $ satisfy suitable conditions, and $ f(x) $ may change sign in $ \mathbb{R}^N $. Using Nehari manifold and fibering maps, the existense of multiple solutions is established. Moreover, the existence of sign-changing solution is obtained for $ f(x)\equiv0 $. Our results generalize some recent results in the literature.
Approximate solutions of the $ 2 $D space-time fractional diffusion equation via a gradient-descent iterative algorithm with Grünwald-Letnikov approximation

Published: March 2022

We consider the two-dimensional space-time fractional differential equation with the Caputo's time derivative and the Riemann-Liouville space derivatives on bounded domains. The equation is subjected to the zero Dirichlet boundary condition and the zero initial condition. We discretize the equation by finite difference schemes based on Grünwald-Letnikov approximation. Then we linearize the discretized equations into a sparse linear system. To solve such linear system, we propose a gradient-descent iterative algorithm with a sequence of optimal convergence factor aiming to minimize the error occurring at each iteration. The convergence analysis guarantees the capability of the algorithm as long as the coefficient matrix is invertible. In addition, the convergence rate and error estimates are provided. Numerical experiments demonstrate the efficiency, the accuracy and the performance of the proposed algorithm.

We will establish several fixed point results in new introduced spaces in this manuscript known as fuzzy rectangular metric-like spaces and rectangular b-metric-like spaces. These new results and spaces will improve the approach of existing ones in the literature. Few non-trivial examples and an application also verify the uniqueness of solution.

Authors: Montoro Luigi ,   Dipartimento di Matematica e Informatica, UNICAL, Ponte Pietro Bucci 31B, 87036 Arcavacata di Rende, Cosenza, Italy, Sciunzi Berardino
Published: March 2022

We consider positive solutions to semilinear elliptic problems with Hardy potential and a first order term in bounded smooth domain $ \Omega $ with $ 0\in \overline \Omega $. We deduce symmetry and monotonicity properties of the solutions via the moving plane procedure under suitable assumptions on the nonlinearity.
Knuckle-walking and behavioural flexibility in great apes
Authors: Tarrega-Saunders Emily LR , King Charlotte , Roberts Alice M , Thorpe Susannah KS
Published: March 2022

Kinematic differences in the knuckle-walking gaits of chimpanzees and gorillas have provided crucial evidence to support the theory that knuckle-walking evolved independently in the Pan and Gorilla lineages, rather than being inherited from their last common ancestor. This has been used to refute the idea that hominin bipedalism evolved from knuckle-walking. Extended wrist postures during knuckle-walking in chimpanzees compared with columnar wrist postures in gorillas were associated with chimpanzees’ more arboreal lifestyle, and are supposedly constrained by fundamental differences in carpal morphology. However, more recent kinematic data cast doubt on the presence of two distinct types of knuckle-walking in Pan and Gorilla. It is also becoming clear that primates demonstrate substantial flexibility in their locomotor ecology to adapt to habitat conditions, indicating that species-specific stereotyping of locomotion is inappropriate. Furthermore, the potential for plasticity in anatomical development presents challenges to evolutionary predictions that are based on tight links between skeletal form and locomotor function. Given the accumulating evidence showing substantial arboreality in gorillas, this study investigates wrist kinematics during both arboreal and terrestrial knuckle-walking in captive chimpanzees and gorillas, to address the hypothesis that previously reported kinematic differences are phylogenetically constrained, rather than merely a consequence of environment. We find that when the arboreal knuckle-walking behaviour of gorillas is considered, gorillas exhibit more extended wrist postures than chimpanzees, and are therefore capable of the same kinematic responses to arboreal supports. We propose that knuckle-walking epitomises a shared inheritance of behavioural flexibility in chimpanzees and gorillas, rather than either a shared inheritance of knuckle-walking itself or independent evolution of knuckle-walking in response to different environmental pressures. We suggest that future studies of hominoid locomotion consider a species’ full range of environmental contexts, as well as the potential influence of developmental plasticity on locomotor anatomy, in order to make more robust conclusions about the evolution of locomotor behaviour.
Deep Learning in Instructional Analysis, Design, Development, Implementation, and Evaluation (ADDIE)
Authors: Rahman Mahbubur , Duran Mustafa
Published: March 2022

The authors emphasize the application scope of the deep learning (DL) technologies in the instructional analysis, design, development, implementation, and evaluation of the educational tools that can enhance the 21st-century modes and models of learning and instruction. The latest trend in the remote learning systems opens a wonderful opportunity for the DL technologies to be integrated with these systems that can impact the way of learning, teaching, design, and development of such systems. The DL technologies provide the data driven decisions and analytical outcomes that can be integrated with the educational technologies. The existing educational technologies and remote learning systems lack in such integrated DL services that can impact the overall education learning systems of the 21st century. The learners and instructors can also benefit from such DL-integrated educational tools. The authors expand further details on the application and implication of the DL services mentioned above in the chapter.
Prevention Is Better Than Cure

Published: March 2022

One of the common uses of artificial intelligence in higher education is learning dashboards, which aim at collecting and analyzing student information and providing feedback to students. Despite limited studies on dashboards in language learning, this chapter describes the design, development, and evaluation of a dashboard designed for a university English course, aiming to provide insights to learning designers, teachers, and researchers. The Course Diagnostic Report was developed after consulting with subject leaders, and it was piloted with students. The results of the pilot showed students were satisfied with this dashboard, showing average scores of the previous cohort of students and suggestions for improvement. Still, students requested better suggestions and sophisticated visualizations to understand their standing in the course. By describing the whole process of development and evaluation, this chapter provides insights on how future dashboards could be designed with better visualizations and the potential of this project for teachers with little knowledge of dashboards.
Retrospective analysis of Vitek®2 performance compared to manual broth micro-dilution for colistin susceptibility testing of Acinetobacter baumanniicomplex isolates in South Africa
Authors: Fadana Vuyolwethu , Thomas Teena , Von Knorring Nina
Published: March 2022

The manual broth micro-dilution (mBMD) is the recommended reference method for colistin minimum inhibitory concentration determination; however, it is not as readily available in South Africa as the Vitek®2. This retrospective study compared the performance of Vitek®2 against mBMD in determining the colistin minimum inhibitory concentration of 337 extensively drug-resistant Acinetobacter baumannii complex isolates. Vitek®2 yielded a categorical agreement of 89%, an essential agreement of 56%, a major error rate of 8% and a very major error rate of 55%. The Vitek®2 is not an alternative to mBMD for colistin susceptibility testing.
Psychometric description of the Life Orientation Test-Revised in a South African sample: A pilot study
Authors: Van Wijk Charles H.
Published: March 2022

The relevance of dispositional optimism – as measured by the Life Orientation Test-Revised (LOT-R) – in health psychology has been convincingly demonstrated in numerous cross-national studies; however, empirical evidence of its psychometric quality and normative parameters in the South African context are lacking. Firstly, this pilot study aimed to replicate previous international psychometric and normative data analyses, and secondly, to extend the investigation into associations with clinical measures of mental health and associated measures of general psychological well-being and resilience in a South African sample. A sample of 755 adults from South African workplaces (42% women, aged 19–62 years) completed the LOT-R and a selection of self-rated measures of clinical mental health and general psychological well-being and resilience. Life Orientation Test-Revised total mean scores were comparable with international samples, with normative reference data supplied to interpret individual scores. Confirmatory factor analysis suggested a bi-dimensional model as best fit, and two independent factors were identified, namely, optimism and pessimism. Significant correlations with measures of psychological health and well-being were observed. Mental health constructs were better characterised by the presence of pessimism than the absence of optimism. No significant age or gender effects were observed but the role of language requires further clarification. This study provided a psychometric description of the LOT-R in a South African sample, including support for both the bi-dimensionality of the LOT-R in this context and its construct validity. The study further provided preliminary normative data for a local sample against which individual scores can be interpreted.
