Multi-Objective Economic Environmental Dispatch of Variable Hydro-Wind-Thermal Power System
Authors: Dey Suman Kumar , Dash Deba Prasad , Basu Mousumi
Published: March 2021

This article presents a multi-objective economic environmental/emission dispatch (EED) of variable head hydro-wind-thermal power system. The combination of NOx emission, SO2 emission, and fuel cost are minimized for non-smooth hydrothermal plants while satisfying various operational constraints like non-smooth fuel cost, penalty coefficient, and wind power uncertainty. The objectives—cost, NOx emission, and SO2 emission—are optimized at the same time. In this research, the non-dominated sorting genetic algorithm-II (NSGA-II) has been employed for solving the given problem where the total cost, NOx emission level, and SO2 emission level are optimized at the same time while satisfying all the operational constraints. The simulation results that are obtained by applying the two test systems on the proposed scheme have been evaluated against strength pareto evolutionary algorithm 2 (SPEA 2).
An Efficient Routing Algorithm for IoT Using GWO Approach
Authors: Sharma Sharad , Kapoor Aparna
Published: March 2021

The internet of things (IoT) is a technology representing a rapidly ubiquitous development. The technologies supporting the IoT are becoming significant as it forms the basic need to analyze the environment and making it smarter. So far, the internet in context of IPs is considered as the largest network globally. The collection of data that includes the process of harvesting the monitored data is sensed by a huge number of participating sensors, which presents a challenging task due to its openly built technical issues resulting from typical limitations of WSNs (delivery time, energy, bandwidth) to the lack of standardized data collection of widespread WSN, required for practical deployment in both the upcoming and existing scenarios of IoT. This paper improves the above critical issue with optimizing the process of routing using the algorithm grey wolf optimization (GWO) which represents semantic form of optimization that typically reduces the drop, time delay, and energy.
Assisted-Fog-Based Framework for IoT-Based Healthcare Data Preservation
Authors: Sarrab Mohamed , Alshohoumi Fatma
Published: March 2021

Healthcare has witnessed a technological advancement in improving the quality of care and speeding the process of diagnosing patients due to its intervention with the internet of medical things. IoT in healthcare (H-IoT) plays a significant role in facilitating the process of diagnosing and detecting diseases. Different IoT-based medical sensors are used to measure biometrics and send them to the cloud for more analysis. However, the sensed data are massive and vary in their criticality level in which some sensed data are more critical (health-related data) than others. Moreover, computing such critical data in the cloud encounters some delay which is not preferable in real-time monitoring applications. Thus, this work proposes an IoT-fog-based framework to classify the streamed data according to their criticality level and compute the critical data in the fog to detect abnormalities with low latency and high response time. Before designing the proposed work, an analysis was conducted to explore the real data collected by IoT-based medical apps. The exploration of the data involved downloading and manually analyzing up-to-date privacy policies of eight IoT-based medical apps that provide details about data collection practices. The study showed that the streamed data in H-IoT include medical sensors data, apps registration data (personal information), device information, and other information related to cookies. The proposed work introduced the design of fog-based data classification and the algorithm for such classification. The implementation and evaluation of the proposed framework is future work.

Published: March 2021

In a competitive world, companies are looking to gain a positive reputation through these clients. Electronic reputation is part of this reputation mainly in social networks, where everyone is free to express their opinion. Sentiment analysis of the data collected in these networks is very necessary to identify and know the reputation of a companies. This paper focused on one type of data, Twits on Twitter, where the authors analyzed them for the company Djezzy (mobile operator in Algeria), to know their satisfaction. The study is divided into two parts: The first part was the pre-processing phase, where this research filtered the Twits (eliminate useless words, use the tokenization) to keep the necessary information for a better accuracy. The second part was the application of machine learning algorithms (SVM and logistic regression) for a supervised classification since the results are binary. The strong point of this study was the possibility to run the chosen algorithms on a cloud in order to save execution time; the solution also supports the three languages: Arabic, English, and French.

Authors: Hamdaoui Nabila , Idrissi Mohammed Khalidi , Bennani Samir
Published: March 2021

Over the last years there has been a growing interest in the use of educational games as learning tools. Educational games have proven to contribute in enhancing student motivation, increasing their engagement and providing them with personalized and adaptive learning. Learner modeling is a prerequisite when it comes to adaptive learning; it is used to represent student's knowledge, needs, and characteristics. This paper presents a modeling technique based on fuzzy logic that uses gameplay data and expert rules to predict learners preferred learning and playing styles. To test the fuzzy rule-based systems, the educational game Woodland was designed bearing in mind the VARK learning styles and the Bartle playing styles. High school students played the educational game Woodland and the results of the FRBSs were compared with the result of the questionnaires. A great correlation was found between the FRBSs results and the questionnaire results.
Anatomical variations of sphenoid sinus based on computerized tomography (CT)
Authors: Ekanayake L. S. B.
Published: March 2021

ObjectivesCurrently in Sri Lanka otorhinolaryngologists are vastly involved in   functional endoscopic sinus surgery (FESS), while transsphenoidal approach to sellar lesions is becoming popular among neurosurgeons. There is a possibility of endoscopic supra sellar, lateral skull base and clival surgery to take off in near future although no sufficient database is available about the anatomical variations of the sphenoid sinuses of Sri Lankans. This research is aimed at filling this deficit.Design and MethodsA cross sectional retrospective study of 200 CT scans of 0.5mm intervals of the ‘nose, paranasal sinus and brain” of Sri Lankans who were seen at district general hospital Trincomalee were analyzed. Details were collected regarding pneumatization, sellar budge, protrusion and dehiscence of the walls of maxillary nerve (MN), optic nerve (ON), vidian nerve (VN) and internal carotid artery (ICA) and the different types and attachment of the sphenoid sinus septum.ResultsWe found no conchal pneumatization but 100% of the study population to have presellar area of the sphenoid body pneumatization, 87% to have sellar and 39.5% to have post sellar area of the sphenoid bone pneumatization. Superior extension of pneumatization into anterior clinoid process (ACP) was found among 13.5% and extension in to posterior clinoid process (PCP) in 4.5%. Lateral extension in to opticocarotid recess was found in 60% and pneumatization in to greater wing of sphenoid (GWS) was found in 42% while 13.5% had pneumatization of lesser wing of sphenoid (LWS). Anterior pneumatization extended in to vomer and ethmoid bones and was 25%and 19% respectively. Posterior extension in to clivus was 34.5% while pneumatization extended inferiorly in to pterygoid process in 54.5 %. The sellar bulge was well defined in 75.5% and not so in 24.5%. The Intersinus septum was absent in 0.5% while single Intersinus septum was present in 86.5% and 8% had a transverse septum. 29.5% had multiple Intrasinus septum while 64.5 % had accessory septa. Occurrence of protrusion and dehiscence in optic nerve, maxillary nerve, vidian nerve and internal carotid artery were, 54%, 8.5%, 24.5% and 79% and, 23%, 7%, 14% and 57.5% respectively.ConclusionsThe sinus anatomy has a racial difference and regional anatomy varies randomly. Posterior, inferior and lateral extensions of pneumatization could make orientation and relative positioning of vital structures confusing. Septal attachments to   vessels and nerves are much higher than appreciated previously. Individual study with greater attention to detail in CT scans is recommended prior to surgery to minimize complications.

Authors: Karunathilaka K. M. O. V. , Drahaman A. M. P. , Lakshan M. T. D. , Perera M. B.
Published: March 2021

Case overviewA patient who got admitted at term for an elective caesarean section underwent an ‘on admission’ routine nasopharyngeal swabbing for SARS-CoV-2. She developed resistant epistaxis one day after the procedure and was found to have a mucosal injury over the sphenopalatine artery entry point on the left side. She had to undergo an emergency caesarean section followed by endonasal sphenopalatine artery ligation. The epistaxis was successfully dealt with and the mother and baby were discharged 48 hours after surgery. ConclusionsProper training in nasopharyngeal swab technique is required. Departments need to consider having biodegradable nasal packing material for such instances. In such injuries early endonasal sphenopalatine artery ligation (ESPAL) should be considered as traditional methods available to us were not successful.

Melioidosis is an infectious disease caused by the bacteria Burkholderia pseudomallei. It has a variety of clinical manifestations ranging from localized abscess, to severe pneumonia to fatal septicaemia. Sinonasal and orbital manifestations of Melioidosis are rare [1]. This is the first reported case of Melioidosis presenting with orbital cellulitis and rhinosinusitis in Sri Lanka. A 42-year-old patient with diabetes mellitus presented with pyrexia of unknown origin, multiple abscesses in the leg, periorbital cellulitis and rhinosinusitis. Initial investigations did not reveal a diagnosis. Eventually it was diagnosed as Melioidosis with a positive blood culture and successfully managed with long term antibiotics. ConclusionEarly identification and aggressive management is needed to reduce the morbidity and mortality of Melioidosis.  Awareness amongst clinicians of different specialties is important as this disease has variety of manifestations.
Maxillary swing approach - Sri Lankan experience
Authors: Dayasena R. P. , Wickramanayaka W. S. S.
Published: March 2021

Introduction:The maxillary swing approach is one of the trans maxillary surgical approach techniques used in otorhinolaryngology. It gives wide exposure to the nasopharynx, orbital apex, sphenoid sinus pterygopalatine fossa, infra temporal fossa and middle cranial base. This enables en bloc resections of tumour and proper visualization.     Objectives:To study patients who underwent this procedure during the last five years with regard to indication, technique, and complications.To compare our patient outcomes with the published literature.To identify the factors leading to complications with recommendations to reduce them in the future.Methods:Retrospective analytical study was done on patients operated from 2015 to 2020 at the ENT Unit C of the National Hospital of Sri Lanka (NHSL).Results:A total of 14 patients underwent maxillary swing approach during the study period. The most common indication was angiofibroma. About 28% had an unacceptable scar following the surgery, which was the most occurring complication while 2 patients had recurrences during this period.Conclusion:Maxillary swing is a useful surgical approach with no major complications in our series. Commonest complication was an unacceptable scar (28%).  Other complications were palatal fistula and nasal speech. It is postulated that further refinement of the technique will reduce these complications.

Published: March 2021

Global Proprioceptive Resonance (GPR) is a recently developed approach conceived to solicit the various cutaneous mechanoreceptors, through application of mechanical multifocal vibration at low amplitude and at definite body sites, limiting the stimulation of the profound structures. This interventional study evaluated the effects of GPR on cardiorespiratory function during the post-exertional recovery period. A group of volunteers involved in Triathlon (a multisport discipline consisting of sequential swim, cycle, and run disciplines higly demanding in terms of metabolic engagment), underwent two maximal incremental exercise tests until exhaustion followed alternatively to (a) a 13 minutes section of GPR or (b) a standard low intensity exercise acute trend of the same duration. These effects of these two approaches were compared in terms of recovery of: heart rate (HR), respiratory rate (RR), peripheral oxygen saturation (SpO2) and venous lactate concentration (Lac). The physiological parameters (HR, RR, SpO2 and Lac) recorded in the pre-exertion session showed similar values between the 40 volunteers while several differences were recorded in the post-exertion phase. After 6 min of GPR recovery it was recorded a drop in RR below baseline (19.4±4.15 min-1 vs. 12.2± 0.4 min-1; p<0.001) coupled with an increase in peripheral oxygen saturation above the baseline (GPR: 99.0%±0.16% vs. 96.6%±0.77%, p<0.001). Moreover, the most striking result was the drop in lactate concentration measured after 13 min of GPR recovery: 84.5±3.5% in GPR vs 2.9±7.6% reduction in standard recovery (p<0.001). Notably no differences were recorded recovery of heart rate. GPR has promising effects on post-exercise recovery on RR, SpO2 and lactate level on young athletes.

Authors: Zhao Xiang-Sheng , Zeng Yue-Xiang , Zhou Ya-Kui , Li Rong-Tao , Yang Mei-Hua
Published: March 2021

Objectives:

A rapid and sensitive gas chromatography–mass spectrometry (GC–MS) method for quantitative and qualitative analysis of essential oil from Curcuma wenyujin rhizomes was established.

Methods:

The essential oil of C. wenyujin rhizomes was extracted by supercritical CO2 extraction (SFE). Six main bioactive compounds (eucalyptol, β-elemene, curzerene, germacrone, curdione, and curcumol) were analyzed in selected ion monitoring mode (SIM).

Results:

Curzerene is not originally present in C. wenyujin rhizomes, but is a product of the transformation of furanodiene at high temperature. The six target components demonstrated good linearity (R2 > 0.9979) over a relatively wide concentration range. The interday and intraday variations had relative standard deviation values less than 5% and the average recovery ranged from 96.95% to 100.04%. The limit of quantitation ranged from 0.032 to 0.235 μg/mL. The developed method was successfully used to analyze the six compounds in 17 samples collected from different origins. Significant variation was observed for the concentrations of the six compounds. In addition, 51 constituents were identified in C. wenyujin rhizome essential oil, consisting of 87.66% of the total essential oil, including curdione, curzerene, dehydrocurdione, germacrone, 1,4-bis(2-benzimidazoyl)benzene, neocurdione, curcumenone, and β-elemene.

Conclusions:

The proposed method will be useful in the quality control of C. wenyujin rhizome essential oil production.
Integer moments of complex Wishart matrices and Hurwitz numbers

We give formulae for the cumulants of complex Wishart (LUE) and inverse Wishart matrices (inverse LUE). Their large-

N

expansions are generating functions of double (strictly and weakly) monotone Hurwitz numbers which count constrained factorisations in the symmetric group. The two expansions can be compared and combined with a duality relation proved in [F. D. Cunden, F. Mezzadri, N. O’Connell, and N. J. Simm, Moments of random matrices and hypergeometric orthogonal polynomials,

The main result resolves the integrality conjecture formulated in [F. D. Cunden, F. Mezzadri, N. J. Simm, and P. Vivo, Correlators for the Wigner–Smith time-delay matrix of chaotic cavities,
J. Phys. A
49 (2016), no. 18, 18LT01, 20 pp] on the time-delay cumulants in quantum chaotic transport. The precise combinatorial description of the cumulants given here may cast new light on the concordance between random matrix and semiclassical theories.
Infinitely many new families of complete cohomogeneity one G$_2$-manifolds: G$_2$ analogues of the Taub–NUT and Eguchi–Hanson spaces
Authors: Foscolo Lorenzo , Haskins Mark , Nordström Johannes
Published: March 2021

We construct infinitely many new 1-parameter families of simply connected complete non-compact G

_2

-manifolds with controlled geometry at infinity. The generic member of each family has so-called asymptotically locally conical (ALC) geometry. However, the nature of the asymptotic geometry changes at two special parameter values: at one special value we obtain a unique member of each family with asymptotically conical (AC) geometry; on approach to the other special parameter value the family of metrics collapses to an AC Calabi–Yau 3-fold. Our infinitely many new diffeomorphism types of AC G

_2

-manifolds are particularly noteworthy: previously the three examples constructed by Bryant and Salamon in 1989 furnished the only known simply connected AC G

_2

-manifolds.

We also construct a closely related conically singular G

_2

-holonomy space: away from a single isolated conical singularity, where the geometry becomes asymptotic to the G

_2

-cone over the standard nearly Kähler structure on the product of a pair of 3-spheres, the metric is smooth and it has ALC geometry at infinity. We argue that this conically singular ALC G2-space is the natural G

_2

analogue of the Taub–NUT metric in 4-dimensional hyperKähler geometry and that our new AC G

_2

-metrics are all analogues of the Eguchi–Hanson metric, the simplest ALE hyperKähler manifold. Like the Taub–NUT and Eguchi–Hanson metrics, all our examples are cohomogeneity one, i.e. they admit an isometric Lie group action whose generic orbit has codimension one.

Andrew Grove (founder CEO Intel) defines strategic inflectionpoints as what happens to a business when a major event alters itsfundamentals. The Covid-19 pandemic is one such historic event thatis changing fundamental business assumptions in the Oil industry.Companies with a hunter-gatherer mindset will ride this wave withthe help of technologies that make their operations lean andefficient. Current developments in AI, specifically aroundCognitive Sciences is one such area that will empower the earlyadopters to a many-fold improvement in engineering and researchproductivity. This paper explores 'how to augment the humanintelligence with insights from engineering literature, leveragingCognitive AI techniques?'. The key challenge of acquiringknowledge from engineering literature (patents, books, journals,articles, papers etc.) is the sheer volume at which it growsannually (100s of millions existing and new papers growing at 40%year-on-year as per IDC). 6 million+ patents are filed every year,of which a mere 20-40% are relevant to any technology domain. It ishumanely impossible to scour, review and take the right decisionsby reading them all. This paper describes key cognitive techniqueslike concept extraction, cause-effect formulation, sentimentanalysis, document summarization, topic modeling, automaticmetadata extraction etc., that conforms to the analyticalmethodology used by E&P researchers worldwide. Such techniquescan also be applied to legacy internal data of energy companies,empowering digitalization and knowledge management initiatives. Cognitive techniques have been around for a while now (firstgeneric patents from IBM in early 1990s) but have never beenapplied to the engineering world, until the 2010s when IHS Markit(under entity Invention Machine Corp.) patented and productizedthis as an engineering research, problem solving and innovationplatform. This paper also explores the efficiency gains and valuesaccrued by the researcher community, while using IHS Markit'sCognitive AI platform.

Published: March 2021

Atualmente, a educação ambiental pode ser compreendida como sinônimo de reflexão e ação, que se desenvolve a partir de um processo educativo, permanente e contínuo tendo como objetivo, superar a visão meramente ecológica, transpondo o olhar para uma dimensão mais abrangente, com discussões de questões políticas, sociais, econômicas, culturais e ambientais (SPIRONELLO et al. 2012). As questões ambientais vêm sendo consideradas cada vez mais urgente para sociedade devido à falta de conhecimento, fazendo com que haja a necessidade da escola em desenvolver projetos de pesquisa sobre o meio ambiente. Sendo assim, o referido trabalho teve como objetivo analisar as concepções sobre meio ambiente dos alunos do 6º ano de uma Escola Municipal, no município de Aracaju/SE. Foram aplicados 42 questionários com perguntas abertas e fechadas, sendo a análise feita de forma qualitativa e quantitativa. Observou-se que os educandos têm uma visão ampla em relação à questão ambiental. Entretanto, também pode-se concluir que os professores não esclarecem seus alunos sobre a temática ambiental e as consequências que os problemas ambientais podem trazer ao meio ambiente.

Published: March 2021

Ulcerative colitis is chronic inflammatory bowel condition which is increasing in prevalence in modern era particularly in age group of 20 to 40years. The exact cause of this disease is unknown yet. Symptoms of UC are altered bowel habits, increased frequency of defecation, bleeding per rectum, mucus mixed stool and tenesmus etc. Associated symptoms are weight loss, weakness, fatigue etc. On the basis of these features UC can be compared with Rakta atisaar. UC is disease of nature with in between symptom free periods. In con-temporary science there is no curative treatment for UC. Symptomatic relief is provided with steroidal drugs and drugs like salphasalazine. So, this is need of hour that a protocol should be designed to provide relief to patient suffering from this disease. Present case study focuses on holistic approach towards entity under con-sideration rather than single formulation of therapy as the disease deteriorates physical and mental wellbeing of patient. A three months of treatment with proper lifestyle led to complete relief in symptoms.

Expectations in the Foreign Language Classrooms: A Case Study
Authors: Ketsman Olha
Published: March 2021

Research shows the strong correlation between expectations and student achievement across different disciplines. However, little research has been conducted regarding the role of discipline specific classroom expectations in student academic achievement. This multiple instrumental case study discusses expectations in two rural Spanish high school classrooms in which teachers produce d the highest achieving students. The data was collected through classroom observations, one-on-one audiotaped interviews with teachers and exploration of instructional materials. The study provides insights about the role of expectations in foreign language classrooms and offers examples of foreign language pedagogical practices that reflect high expectations. The study concludes that expectations shape the learning process in Spanish high school classrooms and contribute to high student achievement. Foreign language educators, faculty of teacher preparation programs, employees of professional development institutes, administrators and state teacher education policy makers will benefit from findings of the study by receiving a better understanding of the role of expectations in the foreign language classroom.
Contextualizing Theories and Practices of Bricolage Research
Authors: Rogers Matt
Published: March 2021

Within the last decade, bricolage, as an approach to qualitative inquiry, has gained popularity in academic circles. However, while conceptual and concrete precedents exist, the approach has remained relatively misunderstood, and unpopular, in broader research communities. This may be because the complexity of the approach has stymied widespread discussions and commentary. This article means to address this concern by providing a thick, yet accessible, introduction to bricolage as an approach to qualitative inquiry. While researchers and scholars have conceptualized bricolage, few have attempted to provide an overview of how the concept emerged in relation to qualitative research. Further, while the literature on bricolage offers invaluable conceptual insights, lacking is a survey that provides clear examples of how bricolage has been implemented in research contexts. Therefore, while greatest attention in this article is devoted to contextualizing bricolage and introducing influential theorists, it also provides key examples of research that adopts the bricolage approach. In drawing on a plurality of sources, the article provides a thick discussion of the complex bricolage project; one that can be beneficial to both novice and seasoned researchers who pursue alternative methodological approaches.
A Preliminary Qualitative Evaluation of the Virginia Gold Quality Improvement Program
Authors: Craver Gerald , Burkett Amy
Published: March 2021

Certified nursing assistants (CNAs) perform an important role in the long-term care system because they provide the majority of paid care to nursing facility residents. Unfortunately, annual CNA turnover often exceeds 100 percent nationally. Many factors account for this, including stressful working conditions, low pay, and limited benefits. The end result of high turnover is compromised continuity of care for residents, which often leads to poor quality and substandard care. In an effort to improve quality of care and staffing, the Virginia Department of Medical Assistance Services in 2009 implemented a pilot program, known as the Virginia Gold Quality Improvement Program, which provided funding to five nursing facilities to develop projects that improved working conditions for CNAs. This study presents the results of an evaluation performed on the program toward the end of its first year using 10 CNA and resident focus groups. Eight themes emerged from the focus groups, suggesting that both quality of care and working conditions improved in the pilot facilities after the program was implemented. However, these findings are preliminary and additional research is needed to more fully understand how the program influenced conditions in the pilot facilities.
“A play is not a journal article:” A Review of Johnny Saldaña’s Ethnotheatre: Research from Page to Stage
Authors: Davis C.
Published: March 2021

Johnny Saldaña’s (2011) book, Ethnotheatre: Research from Page to Stage, does exactly what it sets out to do: It is a hands-on guide that walks researchers across disciplines step-by-step through interpreting and representing data in an ethnodramatic format. It really is “research from page to stage.” For those with little theatre experience, Saldaña provides excellent suggestions for additional readings and comparisons of different types of plays. There is much merit in this book as a text for a qualitative research class or special interest class. The exercises provided are great way for students and researchers to be more reflective as they move towards ethnodrama or autoethnodrama as a new form of writing.
Recursive Frame Analysis: A Practitioner’s Tool for Mapping Therapeutic Conversation
Authors: Keeney Hillary , Keeney Bradford , Chenail Ronald
Published: March 2021

Recursive frame analysis (RFA), both a practical therapeutic tool and an advanced qualitative research method that maps the structure of therapeutic conversation, is introduced with a clinical case vignette. We present and illustrate a means of mapping metaphorical themes that contextualize the performance taking place in the room, recursively enacted to produce a lineal progression from an opening act to a closing act. RFA is offered to therapists, supervisors, teachers, and researchers as an exit from impoverished ways of framing both the choices we have in how to work with clients as well as the ways in which pedagogy is structured and research conducted.

Published: March 2021

The concept of wellness provides a positive view of life development that can support psychological support and counseling. There is little in the literature about wellness and seniors, especially women. This study describes one senior woman’s wellness across the life span by addressing two research questions: (a) What are the experiences of one woman’s wellness across the life span as analyzed through the lens of the Indivisible Self (Myers & Sweeney, 2004, 2005) model of wellness; and (b) What experiences does one woman describe related to the model’s second order factors: the Creative Self; the Coping Self; the Social Self; the Essential Self; and the Physical Self? We used an oral history method to gather the narrative and analyzed her narrative using the Indivisible Self model of wellness. Findings include a descriptive picture of wellness for this woman as it relates to the Second Order factors of the Indivisible Self model.
Listening to Their Voices: Middle Schoolers’ Perspectives of Life in Middle School
Authors: Steinberg Mary Anne , McCray Erica
Published: March 2021

This article examines middle schoolers’ perspectives on their lives in middle school. Fifteen middle school students from three middle schools in the Southeast region of the United States participated in a basic qualitative study using focus groups at their schools where they were asked the central question, “If you could change one thing at your middle school, what would it be?” Findings show that students’ desire caring teachers, students want active classrooms, and students’ technology use impacts attitudes towards learning. Implications are that middle-school learning can increase relevance by teachers demonstrating care for students as individuals; structuring opportunities for students to interact with them and each other around real-world problems; and incorporating technology into learning in ways adolescents already use it.
A Grounded Theory of Connectivity and Persistence in a Limited Residency Doctoral Program
Authors: Terrell Steven , Snyder Martha , Dringus Laurie , Maddrey Elizabeth
Published: March 2021

Limited-residency and online doctoral programs have an attrition rate significantly higher than traditional programs. This grounded-theory study focused on issues pertaining to communication between students, their peers and faculty and how interpersonal communication may affect persistence. Data were collected from 17 students actively working on their dissertation in a limited-residency educational technology program. The resultant theory indicated that students felt communication between themselves and peers is possible but not common. Students also indicated that dissertation supervisors are readily accessible but longer than expected response times may contribute to a lack of student success. The results suggest the development and effective use of an online community of practice will support the communication needs of students and faculty.

Authors: Thai Mai , Chong Li , Agrawal Narendra
Published: March 2021

This paper demonstrates the benefits and application of Straussian Grounded Theory method in conducting research in complex settings where parameters are poorly defined. It provides a detailed illustration on how this method can be used to build an internationalization theory. To be specific, this paper exposes readers to the behind-the-scene work to develop a theory on the internationalization of small and medium-sized enterprises based in transition economies. It describes each step from sampling to coding and then to theory formation, explaining the rationale each step of the way. The readers can therefore see how a theory took shape and develop from raw data to refined theoretical propositions/hypotheses.
Women’s Experiences with Postpartum Anxiety: Expectations, Relationships, and Sociocultural Influences
Authors: Wardrop Andrea , Popadiuk Natalee
Published: March 2021

Evidence about anxiety in the postpartum is sparse and contradictory. Our research expands this knowledge by using a qualitative methodology, the Feminist Biographical Method, to explore first time mothers’ experiences of postpartum anxiety. Data collection included 1.5 to 2.0 hour interviews with six women about their experiences of anxiety in their transition to motherhood. We transcribed the interviews and used an iterative hermeneutic coding process to develop themes and subthemes over the course of four coding cycles. The findings include five major themes: (a) experiences of anxiety, (b) expectations of a new mother, (c) issues of support, (d) societal scripts of motherhood, and (e) the transition. One conclusion that we draw is the need for healthcare professionals to provide improved support and validation to new mothers facing postpartum anxiety, by expanding the definition of postpartum distress, especially anxiety, and by better understanding women’s anxiety through culturally - embedded contextual and relational lenses.

Authors: Nurhayati Nung Ati
Published: March 2021

Masa remaja merupakan masa tersulit yang harus dilalui setiap individu yang akan menentukan fase-fase perkembangan kehidupan selanjutnya. Masalah utama dalam kehidupan remaja adalah masalah kesehatan reproduksi yang berkaitan dengan kehidupan seksualitas. Beberapa penelitian menunjukkan bahwa pemahaman remaja tentang kesehatan reproduksi masih rendah terutama terkait dengan perilaku seks bebas. Rendahnya pemahaman tentang kesehatan reproduksi berdampak pada kurangnya pemahaman tentang perkawinan usia dini yang sampai saat ini masih menduduki angka yang cukup tinggi di Indonesia.  Tujuan penelitian ini untuk menkaji bagaimana pemahaman remaja tentang kesehatan reproduksi dan bagaiman tinjauan yuridis perkawinan usia dini dilihat darai Undang-Undang No 1 tahun 1974 tentang Perkawinan. Tinjauan menggunakan sistematik review  mengikuti Panduan Pilihan untuk ulasan Sytematic Review dan Meta Analyses (PRISMA) dengan menggunakan flowchart berdasarkan daftar periksa PRISMA 2009. Rendahnya pengetahuan remaja tentang kesehatan reproduksi remaja menimbulkan dampak seperti meningkatnya angka perkawinan usia dini. Akibat yuridis dari perkawinan di bawah usia, tidak tampak terjadinya pelanggaran terhadap Undang-Undang Nomor 16 tahun 2019 sebagai perubahan Undang-Undang Nomor  tahun 1974 secara jelas, tetapi timbul akibat yuridis lain, yaitu terjadi penelantaran dalam rumah tangga yang bisa dikenai ancaman pidana sesuai UndangUndang Nomor 23 tahun 2004 tentang Kekerasan Dalam Rumah Tangga, jika terjadi perceraian akan timbul akibat hukum terlantarnya anak sehingga terjadi pelanggaran terhadap Undang-undang Republik Indonesia nomor 35 tahun 2014 tentang perubahan atas undang-undang nomor 23 tahun 2002 tentang perlindungan anak
