The growth of InGaN layers on hybrid SiC/Si substrates with orientations (100), (110), and (111) by the HVPE method was studied at temperatures that wittingly exceed the temperature of InN decomposition onto nitrogen atoms and metallic In (1000C). On substrates with orientations (110) and (111), the formation of InGaN nanocrystals was observed. The shape and growth mechanisms of nanocrystals were investigated. It is shown that nanocrystals nucleate on the (111) surface only inside V-defects formed at the points where screw dislocations exit onto the surface. On the (110) surface, nanocrystals are formed only on pedestals that arise during the film growth. An explanation is given for the difference in the growth mechanisms of nanocrystals on substrates of different orientations.

Published: December 2021

The degree of influence of the electromagnetic field on oil dispersed systems depends on the dielectric properties of these systems, in particular oil. Dielectric properties of oil depend on the content of high molecular weight polar components: asphaltenes and resins. In this regard, a study was carried out of the dielectric properties of oil in the radio-frequency range, depending on the content of asphalt-resinous substances in it. The obtained results of experimental studies show the correlation of dielectric parameters with the ratio of the content of resins and asphaltenes in oil.

A harmonic effect on a modified Anishchenko-Astakhov generator capable of demonstrating two-frequency quasi-periodic oscillations in the autonomous mode is considered. The possibility of doubling the three-frequency tori in a non-autonomous system is shown. The possibility of the effect of chaos suppression by an external signal is demonstrated, which leads not only to periodic, but also to quasi-periodic modes when the influence amplitude exceeds a certain threshold.
Developing Conflict Resolution Strategies and Building Resilient Midwifery Students: Protocol for a Mixed Methods Research Study (Preprint)
Authors: Simpson Naomi , Steen Mary , Vernon Rachael , Briley Annette , Wepa Dianne
Published: December 2021

BACKGROUND

Workplace bullying and violence (WBV) are well-documented issues in the midwifery profession. Negative workplace culture, conflict, and bullying are the most common forms of workplace violence experienced by midwives. Workplace violence increases the risk of midwives experiencing burnout, compassion fatigue, psychological trauma, poor mental health, absenteeism, loss of passion for the midwifery profession, job dissatisfaction, and poor job retention. Midwifery students describe workplace violence in the form of physical, emotional, or verbal abuse, and bullying. Therefore, there is a justification to develop conflict resolution strategies and resilience in midwifery students prior to graduation.

OBJECTIVE

Our aim is to develop and facilitate a bespoke education program for South Australian midwifery students to enable them to develop skills in conflict resolution, build resilience, and identify self-care strategies.

METHODS

This study will undertake a preparatory phase summarizing the body of literature on midwifery students’ knowledge, understanding, and experiences of WBV. Following this, a 3-phase sequential mixed methods research design study will be undertaken. In Phase 1, quantitative data will be collected via a semistructured questionnaire and a validated conflict measurement tool, before and after attending an education workshop, and will be analyzed using descriptive and inferential statistics. Results from Phase 1 will inform and guide the development of an interview schedule for Phase 2. In Phase 2, qualitative data will be gathered by facilitating one-to-one interviews and a thematic analysis will be undertaken to gain a deeper understanding of midwifery students’ experiences of WBV. In Phase 3, data integration using triangulation will be undertaken and meta-inferences will be developed via the integration of results and findings from Phases 1 and 2.

RESULTS

The preparatory phase will commence in October 2021. Phase 1 will commence in 2022 with analysis of pre- and posteducation results anticipated to be completed by December 2022. Phase 2 will be developed from findings of the preparatory phase and results of Phase 1. An interpretation of verbatim interview transcripts is estimated to be undertaken by April 2023. Phase 3 of the study is expected to commence in May 2023, and this will involve the analysis of collective evidence gathered from Phases 1 and 2. The anticipated completion date for the study is December 2023.

CONCLUSIONS

The outcomes of this research will provide insights into the prevalence and impact of WBV experienced by midwifery students. The findings of the research will report on levels of knowledge, skills, and confidence, and will assess the impact of a bespoke conflict resolution and resilience education workshop for midwifery students in managing WBV.

Integrative Model of Strategic Environmental Scanning based on Crises Management Approach
Authors: Jain Honey
Published: December 2021

Abstract: The aim of this study is to examine the way top managers scan environmental conditions to diagnose and interpret issues during periods of crisis. Despite each of these processes being widely and individually represented in the research literature, there is a lack of integrative models that examine their internal dynamics in-depth. In this study, structural equation modeling methodology (EQS 6.3) was applied to a sample of 120 top managers to examine how the cognitive orientation of scanning (rational vs. intuitive analysis of environment) may influence final issue categorizations. The overall findings of the current study show that strategic Environmental Scanning is conducted in UNRWA and has a stoical relation with crises management. This relation is weak and need to be strengthen especially during and after the crisis. The study suggest that strategic Environmental Scanning must be conducted permanently for external and internal environment to help UNRWA developing its strategic planning and to be to prepared to deal with potential crises in the future. Keywords: Strategic Environmental Scanning, Crises Management, UNRWA

Authors: Verma Somesh
Published: December 2021

Abstract: This work presents the determination of the mechanical properties (compression, split tensile and flexural) of the specimens (cubes, cylinders and beams). The test specimens are M60 high strength concrete which includes ground granulated blast furnace slag (0%,10%, 20%, 30% and 40%) and fly ash (0% 10%, 20%, 30% and 40%) to obtain the desired resistances and properties. Finally, we used granulated blast furnace in different percentages as cement and concrete were replaced. We prepared concrete cubes, beams and cylinders and stored them for a 28-day cure. The tests are performed after 7, 21 and 28 days. To achieve the desired strength that cannot be achieved with conventional concrete and the current method, a large number of test mixtures with different percentages of fly ash and different percentages of ground granulated blast furnace slag are needed to select the combination of materials.

Authors: Alsaadi Reem , Al Sultan Adam
Published: December 2021

The aim of this study was to investigate the effects of learning station strategies on developing academic achievement and self-regulated learning among middle school students of low socioeconomic status. The sample group consisted of 68 female Saudi students. We applied a quasi-experimental design with an experimental and control group and a pretest and posttest. We examined the correlation between academic achievement and self-regulated learning. The data collection instruments included an academic achievement test and self-regulated learning questionnaire. The results revealed a statistically significant difference between the mean scores of both instruments in favor of the experimental group. Additionally, there was a positive relationship between development of academic achievement and self-regulated learning among the students for the experimental group. The study’s findings suggest that the learning stations created a dynamic classroom, which prompted students to engage in self-regulatory behaviors and develop their knowledge and understanding.

Published: December 2021

This paper presents the results of a pre-experimental design. The study was carried out with a single-group posttest model. In this study, the Turkish Folk Music unit was chosen for investigation as part of Phenomenon Based Learning with 10th grade high school students. In order to carry out the Phenomenon Based Learning process in an effective way, the teacher is meant to be well-prepared in different aspects. Therefore, during the research, the music teacher tried different introductory and follow-up activities. Following this, the opinions of 84 high school students were considered, concerning the activities. Results revealed that the introductory activities have the utmost importance in Phenomenon Based Learning. Although this study was carried out within time constraints, it was evident that these activities had a great impact on the students and the teacher. The students’ discoveries and inferences about both Turkish Folk Music and themselves for the future emerged as promising.
Effects of Gamified Learning on Students of Different Player Traits in Malaysia
Authors: Sanmugam Mageswaran , Selvarajoo Anurita , David Jeya Amantha
Published: December 2021

Diversified learning is the path to supplement students’ needs in the contemporary generation. These students’ lives have revolved around technology since birth; as such, the role of technology cannot be ignored. Furthermore, this was prevalent during the lockdown imposed by the global pandemic which compelled the incorporation of educational technology into student’s lives. As gamification harnesses the power of game elements, identifying how gamified learning affects a student’s game player traits will be vital in identifying whether specific learning methods can invoke, change and cultivate better learning outcomes. This quasi-experimental study involving two groups of students learning computer science in Malaysia was carried out over eight weeks. Findings revealed that most prevalent player traits changes were evident in the primary construct of social player traits, followed by subconstructs of customization, relationship, socializing, and mechanics. These changes are attributed to the need to reach out, communicate, and collaborate with their peers and look into how the system works for them individually, within the context of the learning and explorative needs of students. As such, gamified learning has not only managed to offer a new paradigm into the learning ecosystem but has also shown that positive changes can be cultivated based on these conditions.

Teacher’s Working Condition and Hybrid Teaching Environment – A Narrative Case Study
Authors: Anand Neha , Bachmann Abbey
Published: December 2021

Since the onset of the COVID-19 pandemic, the entire system of education around the world is living each day under rapid experimentation to grapple with unforeseen challenges. The event of the COVID-19 pandemic has not only impacted a student’s track of learning but also disrupted the everyday functioning of schools. In the case of the United States, since the beginning of March 2020, when schools were pushed into remote learning options, most teachers had minimal training and resources to teach online. Teachers faced technological challenges and suffered a severe lack of pedagogical knowledge to engage students in an online platform. The overnight switch of face-to-face to remote teaching has added to existing teacher workloads, including accommodating student learning and engagement on the virtual platform. The narrative study considers the experiences of Ally, a veteran teacher, who experienced doubts about her sense of confidence as a teacher with the overnight change of instructional formats. Qualitative analysis was conducted from two interviews, 12 written reflections, and observation notes. Following a review of relevant literature, we report the narrative account of this teacher’s lived experiences. Next, we present suggestions and implications for research and practice while addressing the following research question: What were the lived experiences of a veteran teacher while pursuing a hybrid teaching instruction format, in both the traditional and online delivery format?
Phyllachora species infecting maize and other grass species throughout the Americas represents a complex of closely related species which vary in their host and geographic range

Published: December 2021

The genus Phyllachora contains numerous obligate fungal parasites that
produce raised, melanized structures called stromata on their plant
hosts referred to as tar spot. Members of this genus are known to infect
many grass species but generally do not cause significant damage or
defoliation, with the exception of P. maydis which has emerged as an
important pathogen of maize throughout the Americas, but the origin of
this pathogen remains unknown. To date, species designations for
Phyllachora have been based on host associations and morphology, and
most species are assumed to be host specific. We assessed the sequence
diversity of 186 single stroma isolates collected from 16 hosts
representing 15 countries. Samples included both herbarium and
contemporary strains that covered a temporal range from 1905-2019. These
186 isolates were grouped into 5 distinct species with strong bootstrap
support. We found three closely related, but genetically distinct groups
of Phyllachora are capable of infecting maize in the United States, we
refer to these as the P. maydis species complex. Based on herbarium
species, we hypothesize that these three groups in the P. maydis species
complex originated from Central America, Mexico and the Caribbean.
Although two of these groups were only found on maize, the third and
largest group contained contemporary strains found on maize and other
grass hosts, as well as herbarium specimens from maize and other grasses
that include 10 species of Phyllachora. The herbarium specimens were
identified based on morphology and host association, but our sequence
data indicates some Phyllachora species are capable of infecting a broad
range of host species and there may be significant synonymy in the
Phyllachora genus and additional work on species delineation and host
specificity should be considered.
MERGERS & ACQUISITIONS IN THE ELEVATOR INDUSTRY: THE USE OF ICTs TO AVOID INFORMATION ASYMMETRY
Authors: Guardia Juan de la , Palacios Miguel , Zurdo Ricardo
Published: December 2021

Mergers and acquisitions operations continue to be one of the most
explored growth strategies in all markets, and this is indeed the case
in the elevator industry. The volume of investments grows year after
year. It is the fastest way to grow in international and domestic
markets, but the reality is that a high percentage of the operations
carried out do not meet the expectations of the investors once the
integration phase has been completed. There are several causes of
failures in mergers and acquisitions processes, such as lack of
commitment from the management, an unrealistic business plan, cultural
shock, etc. But the most common one, and the one with the highest risk
in an acquisition decision, is information asymmetry. During the
negotiation phase a large amount of data is collected, and subsequently
analyzed during the due diligence period, but it may not correspond to
the reality during the integration phase. In this article we will
propose how information asymmetry can be avoided through the application
of information and communication technologies (ICTs) via internet of
things (hereinafter IoT) devices in the elevator industry. This can also
be applied to other industries.

Authors: Tasoudis Panagiotis T. , Varvoglis Dimitrios N. , Vitkos Evangelos , Ikonomidis John , Athanasiou Thanos
Published: December 2021

Objectives: The aim of the study is to compare the safety and
efficacy of unilateral anterograde cerebral perfusion (UACP) and
bilateral anterograde cerebral perfusion (BACP) for acute type A aortic
dissection (ATAAD). Methods: A systematic review of MEDLINE
(PubMed), Scopus, and Cochrane Library databases (last search: August 7
, 2021) was performed according to the PRISMA
statement. Studies directly comparing UACP versus BACP for ATAAD were
included. Random-effects meta-analyses were performed. Results:
Eight retrospective cohort studies were identified, incorporating 2416
patients (UACP: 843, BACP: 1573). No statistically significant
difference was observed regarding in-hospital mortality (odds ratio
[OR]:1.05 [95% Confidence Interval (95%CI):0.70-1.57]),
permanent neurological deficit (PND) (OR: 0.94 [95%CI:0.52-1.70]),
transient neurological deficit (TND) (OR: 1.37 [95%CI:0.98-1.92]),
renal failure (OR: 0.96 [95%CI:0.70-1.32]), and re-exploration for
bleeding (OR: 0.77 [95%CI:0.48-1.22]). Meta-regression analysis
revealed that PND and TND were not influenced by differences in rates of
total arch repair, Bentall procedure and concomitant CABG in UACP and
BACP groups. Cardiopulmonary bypass time (Standard Mean Difference
[SMD]:-0.11 [95%CI:-0.22, 0.44]), Cross clamp time (SMD:-0.04
[95%CI:-0.38, 0.29]) and hypothermic circulatory arrest time
(SMD:-0.12 [95%CI:-0.55, 0.30]) were comparable between UACP and
BACP. Intensive care unit stay was shorter in BACP arm (SMD:0.16
[95%CI:0.01, 0.31]), however, length of hospital stay was shorter
in UACP arm (SMD:-0.25 [95%CI:-0.45, -0.06]). Conclusions:
UACP and BACP had similar results in terms of in-hospital mortality,
PND, TND, renal failure and re-exploration for bleeding rate in patients
with ATAAD. ICU stay was shorter in the BACP arm while LOS was shorter
in the UACP arm.

Percutaneous procedures through femoral access in patients with inferior vena cava (IVC) filter may be at risk of complications. We evaluated the feasibility and safety of left atrial appendage closure (LAAC) through femoral access in patients previously implanted with IVC filter. We described the WatchmanTM device implantation in two patients with formal contraindication for oral anticoagulation. First patient had a GreenfieldTM filter and the second one an OpteaseTM filter, and in this patient an attempt to withdrawal the filter immediately before the LAAC procedure failed. A femoral approach was performed in both patients using a 14 Fr sheath. Before crossing IVC filters, venographies did not detect any thrombus. All steps of IVC filter crossing were performed under fluoroscopic guidance. No immediate or intrahospital complications related to the procedure occurred. Herein, we presented two cases of successful LAAC closure with Watchman device in patients with two different kinds of IVC filters.

This is a series case report of five symptomatic patients presented with diagnosis of sinus bradycardia, first and second degrees atrioventricular (AV) blocks, that were referred to pacemaker implantation. During the screening, a functional cause for the bradycardia and AV blocks were documented by treadmill stress test, 24-hour Holter monitoring and atropine test. After the confirmation of the diagnosis, patients were submitted to cardioneuroablation on an anatomical basis supported by a tridimensional electroanatomical fractionation mapping software. The technique and the acute and short-term results of the cardioneuroablation are described.

Drought is a natural disaster whose frequency is quite high and occurs almost every year. According to the radarbali.jawapos.com page on June 15, 2019, rice fields in Karangasem are threatened by drought. 2000 hectares of agricultural land threatened with drought or did not get irrigation supply because during the dry season the water source used to irrigate the land was drastically reduced and even partly dried up. From the observations of the UPTD of the Horticultural Agricultural Plant Protection Agency (BPTPH) of the Bali Provincial Agriculture Office, until June 2019 there was damage to rice fields due to drought where observations were made since the start of the planting season in May. Drought area information is used to map and calculate the area of drought areas, so that areas with drought potential can be identified. One way to get drought area data is by remote sensing technology. Identification of potential  drought areas is the basic idea for the formation of drought identification applications in East  Bali. The remote sensing application uses the NDDI (Normalized Difference Drought Index) method. NDDI is the result of calculation of the Normalized Difference Vegetation Index (NDVI) which is an index of vegetation parameters and Normalized Difference Water Index (NDWI) which is the value of wetness of vegetation. The images used in this study are Landsat 8 imagery with OLI (Onboard Operational Land Imager) sensor and TIRS (Thermal Infrared Sensor) sensor. The result of the application of drought area identification is the visualization of drought area and the extent of drought area based on the category of very dry, dry, mild dry, normal and non-classification using hectare units.

Jaringan pipa air suatu daerah yang dikelola oleh PDAM (Perusahaan Daerah Air Minum) berfungsi untuk mendistribusikan kebutuhan air bersih bagi masyarakat. Namun, sering kali proses distribusi air bersih ini tersendat yang disebabkan oleh beberapa faktor, seperti pasokan air dari hulu yang menipis, sumber air kotor dan berlumpur, atau jaringan pipa yang bermasalah. Dengan demikian, pada penelitian ini akan dilakukan peninjauan dan pembahasan terhadap solusi-solusi berbasis Internet of Things (IoT) yang dirancang oleh para peneliti terkait permasalahan pada sektor jaringan distribusi air publik. Peninjauan dan pembahasan ini bertujuan untuk mengetahui masalah apa sering muncul dan sampai sejauh mana solusi yang dirancang yang bisa dimanfaatkan oleh PDAM. Studi pustaka dilakukan dengan mempelajari artikel-artikel terkait yang dipublikasikan pada jurnal internasional terindeks Scopus yang terbit selama 5 tahun terakhir. Dari penelitian berbasis literature review ini, didapatkan permasalahan yang masih terbuka yang belum diselesaikan yang bisa dirumuskan solusinya lebih lanjut. Salah satunya adalah permasalahan pelanggan yang tidak mendapatkan informasi terkini terkait kondisi jaringan air publik.

Published: December 2021

Klasifikasi kunci gitar merupakan suatu bentuk klasifikasi guna melakukan pengenalan pada kunci gitar dengan menggunakan hasil rekaman file suara gitar dengan format mono.wav. Proses pengenalan dilakukan karena pendengaran manusia umumnya memiliki kepekaan yang beragam untuk dapat mendengar dan mengenali kunci gitar, sebagai orang awam yang belum terbiasa memainkan alat musik biasanya kebingungan untuk mengenali jenis kunci gitar. Metode Spectral Analysis dan Metode K-Nearest Neighbor (KNN) digunakan untuk mengetahui seberapa efektif proses pengenalan dan pengklasifikasian kunci gitar. Metode Spectral Analysis merupakan metode yang digunakan untuk mendapatkan fitur yang ada pada sebuah kunci gitar yang terdiri dari 5 fitur yaitu Spectral Kurtosis, Spectral Centroid, Spectral Skewness, Spectral Slope, dan Spectral Rolloff. Kelima fitur Spectral kemudian digunakan dalam proses pengenalan menggunakan metode K-NN. Pengujian sistem dengan chord standar menghasilkan tingkat akurasi yang paling tinggi yaitu 83% dan pengujian sistem dengan gitar half size menghasilkan tingkat akurasi yang paling rendah yaitu 23%.

Kecelakaan lalu lintas merupakan salah satu peristiwa yang sering terjadi dijalan yang dapat menyebabkan adanya korban jiwa. Pentingnya penelitian bertujuan untuk meramalkan kasus Kecelakaan Lalu Lintas di Provinsi Bali. Peramalan dilakukan dengan menerapkan teknik penambangan data atau yang sering disebut dengan data mining. Penambangan data (data mining) merupakan sekumpulan proses yang digunakan untuk mencari nilai yang tidak bisa didapatkan secara otomatisl. Peramalan dalam penelitian ini menggunakan Metode Support Vector Regression dengan 2 kernel yaitu Kernel Polynomial dan Kernel RBF. Data yang digunakan dari Tahun 2006 sampai dengan Tahun 2018. Data tersebut dikelompokkan menjadi data training dengan jumlah (9 data) dan data testing dengan jumlah (4 data). Hasil peramalan yang didapatkan dibandingkan dengan nilai persentase MAPE yang dihasilkan. Hasil peramalan menggunakan kernel Polynomial menghasilkan nilai Persentase MAPE sebesar 7,95% dimana hasil peramalan artinya “Sangat Bagus”. Hasil peramalan menggunakan kernel RBF memiliki persentase MAPE yang lebih besar yaitu 13.35% yang artinya hasil peramalan “Bagus”. Penggunaan dari dua kernel tersebut menyatakan bahwa dalam Metode Support Vector Regression untuk meramalkan kasus kecelakaan lalu lintas lebih tepat menggunakan Kernel Polynomial. Semakin kecil nilai persentase MAPE yang dihasilkan maka semakin bagus juga hasil peramalan yang didapatkan.
