The Power of Resilience: A Theoretical Model to Empower, Encourage and Retain Teachers
Authors: Taylor Janice
Published: March 2021

Due to the many challenges that teachers face in today’s classrooms to facilitate the academic success of all children and to meet federal and state accountability standards, having both the competence and the ability to adjust to meet these challenges are required. Teacher retention is an ongoing issue in the United States; teachers who lack these traits may have a negative impact on teacher retention. Resiliency is a critical element that teachers need to meet these challenges and remain in the education profession. In this study, the stories of four female African American teachers who taught in the same school district in a rural community in the South before, during, and after desegregation, were examined. Using qualitative methodology and a narrative inquiry technique, the data analyzed from the stories of the four women confirmed eight themes of resilience as identified in Polidore’s Theory of Adult Resilience in Education (2004). An additional resilience theme, efficacy, also emerged. The additional theme provided an enhanced conceptualization and construct of Polidore’s Theory of Adult Resilience in Education model. With the massive challenges facing educators today, the stories of the four teachers can be used to empower, encourage and retain teachers in the education profession.
Inquiry into Issues of Trustworthiness and Quality in Narrative Studies: A Perspective
Authors: Loh Jason
Published: March 2021

Many narrative studies subscribe to the criterion of verisimilitude as a form of quality check. However, such a criterion does not fully nor explicitly address the issue of quality or rigour. This paper examines a possible set of necessary criteria for evaluating narrative studies. It draws on the quality literature from the broader qualitative research field as well as the narrative research field. Specifically, it deals with the need to have a list of considerations to refer to in order to ensure acceptability and recognition of narrative studies’ rigour. This paper posits that issues of trustworthiness, narrative truth, verisimilitude and utility need to be attended to for any narrative study to ensure its quality.
Bracketing in Phenomenology: Only Undertaken in the Data Collection and Analysis Process
Authors: Chan Zenobia , Fung Yuen-ling , Chien Wai-tong
Published: March 2021

Our aim with this article is to demonstrate how the researchers use bracketing as a method of demonstrating the validity after initiating a phenomenological study. Although bracketing is a method of demonstrating the validity of the da ta collection and analysis process in most phenomenological studies, how the researchers use them in practice is rarely demonstrated explicitly. We collected data through our experiences in preparing a phenomenological research study. We suggest that the concept of bracketing should be adopted upon initiating the research proposal and not merely in the data collection and analysis process. We propose four strategies for doing bracketing that are guided by the thinking activity of reflexivity: mentality assessment and preparation before deciding the research paradigm, deciding the scope of the literature review according to the prevailing gate - keeping policy, planning for data collection using semi - structured interviews guided by open - ended questions, and planning for data analysis using Colaizzi’s method. Our proposition highlights that thorough preparation for doing bracketing is essential before entering the data collection and analysis process in phenomenology, because they are sequentially related.
Toddling Towards Childhood: A Bibliometric Analysis of the First QROM Lustrum (2006 - 2010)
Authors: Infante Eduardo
Published: March 2021

The first years in the life of a journal are the most difficult ones as editors need to advertise it effectively and attract worldwide researchers to safeguard its launch and maintenance. This study provides a bibliometric analysis of the first lustrum of the journal Qualitative Research in Organizational and Management (QROM) in an attempt to assess its production both in methodological and conceptual terms. The sample was made up of 66 articles by 109 (co - )authors from 66 institutions. A total of 53.2% of contributors were female and were responsible for 42.4% of the single - authored articles (compare to 34.8% of only - male articles). Eight “invisible schools , ”, 37.5% national ones, were obtained by relating authors to sharing co - authors (grade 1), institutions (grade 2) or cities (grade 3). The most productive authors were Cassell, Grandy, and McKenna, the first two being developers of invisible schools. The number of articles, theoretical perspectives, and diversity of applied techniques has increased in QRO M over the lustrum period with UK and Canada as most prolific countries followed by USA, Sweden, and Australia. Most articles dealt with organizational and managerial issues under discourses or narrative perspectives using interviews and sense - making theories. The evolution of these findings is also presented.
A Guidebook and a Research Model: A Review of Doing Excellent Small - Scale Research
Authors: Clancy Michael
Published: March 2021

A guide book and a research model – Doing Excellent Small - Scale Research (Layder, 2013) provides both. First, Professor Layder has written a book that is just what he intended: “an introductory guide” for research students. It provides a process for clearly defining problem and topic questions, advice regarding research designs, methods for data collection and analysis, real - life examples, and a logical sequence tying everything together. Second, the author offers an Adaptive Research Model as a practical approach for conducting social research. This model and this book are recommended (by the reviewer) for research students and teachers, both undergraduate - and graduate - level.
Exploring the Use of Mobile Technology in Qualitative Inquiry in Africa
Authors: Johnson Ane
Published: March 2021

In this article I explore how mobile phones may facilitate greater access to participants and higher participation rates in qualitative inquiry in Africa. Qualitative researchers face a number of ethical and procedural challenges when collecting data in the field. But with the explosion of mobile phone usage, many of these obstacles to data collection may be ameliorated, facilitating greater access to participants, to data, and to important findings. I use the example of a research study on the connection between development and higher education at two public universities in Kenya to illustrate how mobile phones played an unexpected role in data collection. Finally, I discuss preliminary recommendations for using the mobile phone to contend with the myriad challenges to rigorous qualitative research in Africa.
Conceptions of Competency: A Phenomenographic Investigation of Beginning Teachers in Malaysia
Authors: Goh Pauline
Published: March 2021

I use phenomenography, which is an interpretive research approach, to seek and to discover what beginning teachers in Malaysia conceive and understand as competence in relation to what they do everyday as teachers. Phenomenographic approach is used because of its potential to capture variation of understanding, or way of constituting, the conceptions of competency. The outcomes of this study, therefore, are: (a ) Categories of description which capture the critical dimensions of how beginning teachers in Malaysia understand the conceptions of competency, and, (b ) An outcome space that describes the relationships between the categories. The results show that beginning teachers’ conceptions of competence fall into five qualitatively different categories: (a ) Classroom and Behaviour Management, (b ) Knowing Subject Matter, (c) Understanding Students; (d ) Reaching out for Assistance and Support, and (e ) Possessing Values of Professionalism. The relationships between these categories are represented diagrammatically as the outcome space. The empirical data through phenomenography has provided a platform for teachers and teacher educators to ask: (a) " What are the implications, for beginning teachers, of their differing ways of understanding the conceptions of competency" (b) " How can teaching institutions better prepare pre - service teachers for their early years of teaching," and, (c) "How can appraisers (e.g., Principals, Head Teachers, Course Coordinators) use the outcomes to better plan any evaluations of competency?" I discuss each question in the article.
A Phenomenological Study of Falling Out of Romantic Love
Authors: Sailor Joanni
Published: March 2021

Romantic love is considered a necessary ingredient in marriage. In this study, the experience of falling out of romantic love with one’s spouse was examined. Eight individuals who had fallen out of romantic love with their spouse were interviewed. By using Moustakas’ Transcendental Phenomenological method, several themes emerged which provided a description of the experience of the phenomena. These themes included loss of trust, of intimacy, and of feeling loved; emotional pain; and negative sense of self. Gradual decline was identified as a slow, progressive deterioration of the relationship in which over time the romantic love decreased and eventually ended. Pivotal moment of knowing was seen as a specific moment in which there was awareness of no longer being in romantic love. The specific circumstances associated with pivotal moment were different for each participant, but the clarity of the moment was universal. Although not exhaustive in their scope, the identified themes were reported to be a part of the romantic love dissolution experience.
HOW DOES WORKPLACE BULLYING TRIGGER VICTIM'S COUNTERPRODUCTIVE BEHAVIORS? THE MEDIATING ROLE OF PERCEIVED CO-WORKER SUPPORT
Authors:   International Islamic University, Islamabad, Naseer Saima
Published: March 2021

Purpose/Objectives- This study disentangles an important knot in the bullying literature by examining how and through what psychological processes workplace bullying triggers counterproductive work behaviors (CWBs) in its victims. Using the theory of triggered displaced aggression and stressor-emotion model of CWB we hypothesize that workplace bullying as a stressor leads to the development of negative perceptions of coworker support which prompt its targets to strike back by displaying CWBs both towards the source of abuse and redirect it towards others such as co-workers as well as organization. Methodology- By collecting two source field data (N= 334; Self-peer dyads) from employees working in the Education, Banking and Telecom sector of Pakistan, we tested our direct as well as mediation hypothesis using Structural Equation Modeling (SEM) technique. Findings- The results of SEM analysis support all the direct as well as indirect paths clearly suggesting that victims of bullying develop lower perceptions of coworker support which causes them to vent out their frustration creating higher levels of individually as well as organizationally directed CWBs. Practical Implications- Our study extends the mistreatment literature and is beneficial for managers as it examines and tests a unique mechanism of perceived coworker support in the through which a stressful condition of bullying ignites CWBs in its targets towards others and organization.
New Research on Teacher Leadership in Schools: Efficacy of a survey method for analyzing multiple dimensions of leadership
Authors: Blank Rolf
Published: March 2021

In the past decade, teacher leadership has emerged as a key strategy for improving the quality of education in U.S. schools. Major foundations, federal education programs, and professional organizations are providing significant support for teacher leadership as a key strategy for improving the quality of education in U.S. schools. Teachers in U.S. schools have a variety of roles and responsibilities in addition to their primary responsibility of teaching in classrooms. While teacher classroom effectiveness has been the focus of extensive research, the roles of teachers as leaders in their schools, districts, and professional associations have been the subject of less research and analysis. The research design for this study of teacher leadership takes a broad view of the roles of teachers in their school and their profession. The study design follows from research-based constructs of the relationship of teacher leadership to education quality in K-12 education.
Improving Access to the Green Climate Fund: How the Fund Can Better Support Developing Country Institutions
Authors: Caldwell Molly , Larsen Gaia
Published: March 2021

The Green Climate Fund is a globally important source of finance for projects in developing countries that address climate goals. Central to the GCF’s formation is an emphasis on providing funds directly to developing country institutions. Through “direct access” it seeks to fund a diverse set of stakeholders including public, private, and non-governmental organizations from developing countries, using a variety of financial instruments including grants, loans, equity and guarantees. Despite accrediting 62 developing country institutions, 42 of these entities have yet to receive project funding. The GCF has launched several initiatives to support Direct Access Entities with project development and approval including the Readiness Programme, the Project Preparation Facility, the Simplified Approval Process, and the Enhancing Direct Access Pilot, but these are not yet delivering sufficiently to meet the need. There are a number of steps the GCF can take to expand the range of entities that receive project funding by improving support to Direct Access Entities.

In this study, chemical compositions and in vitro antibacterial activities the components of essential oils and extracts of sage (Salvia officinalis L.), rosemary oil (Rosmarinus officinalis L.), lavandin (Lavandula x intermedia var. Super), and hyssop (Hyssopus officinalis L.) against fish pathogens: Gram-negative bacteria (Aeromonas caviae, Aeromonas hydrophila, Vibrio anguillarum, Yersinia ruckeri, Edwardsiella tarda, Pseudomonas aeruginosa) and Gram-positive bacteria (Lactococcus garvieae, Staphylococcus warneri, Vagacoccus salmoninarum) were investigated with Well Diffusion Agar assay. The composition of the essential oils and extracts were analyzed with GC/MS and HPLC, respectively. A total of 42 components in sage, 39 in rosemary, 44 in lavender, and 46 in hyssop were detected. As a result of this study, the sage and rosemary oils exhibited a broad-spectrum inhibitory effect (a strong antibacterial effect against Gram (+) and Gram (-) pathogens). Lavandin oil also showed a strong antibacterial effect against a majority of pathogens. The spectrum of inhibitory activity of hyssop oil was found narrower than other plant oils. In further studies, in vivo antibacterial effects of sage, rosemary and lavandin essential oils should be investigated.

Published: March 2021

Correctional Bureau (BAPAS) plays a very important and strategic role in child criminal case settlement. One form of the settlement is made through diversion, for child to avoid the bad impact of formal child criminal judicature. The research employed a juridical normative research method and statute approach and conceptual approach. The role of Bapas in child criminal case settlement through diversion is quite important and strategic as set forth in Law Number 11 of 2012 concerning Child Criminal Judiciary System, Government Regulation Number 65 of 2015 concerning the Guidelines on the Implementation of Diversion and Dealing with Under 12 (Twelve) Years Old Child, Regulation of Supreme Court of the Republic of Indonesia Number 4 of 2014 concerning the Guidelines on Diversion Implementation in Child Criminal Judiciary System. The constraints found in the diversion implementation are related to remedy for victim and non-optimal post-diversion supervision by the Correctional Advisor of Correctional Bureau (PK Bapas).

Published: March 2021

This study mainly investigated the predictions of the Contrastive Analysis Hypothesis (CAH) on Taiwanese vocational high school EFL learners’ acquisition of two English fricative consonants (/s/ and /θ/) by examining the learners’ relative perceptual difficulty of the consonants. To achieve this purpose, two research questions were devised, and a self-designed listening identification test was carried out. A total of 43 students from a private vocational high school in northern Taiwan participated in this experiment. Their accuracy in perceiving the tested consonants was measured through the identification test. After all the participants’ test scores were gathered, an independent-samples t-test was used to analyze the data. The results of the study showed that the relative perceptual difficulty of the two fricatives for the students was /s/ = /θ/. The finding suggested that Lado’s (1957) CAH could not accurately predict the participants’ acquisition of the consonants in perception.

Nowadays, starting acquaintance to looking for dates through online media is very common. HAGO, an online game application that is currently popular and widely used by Indonesians, has turned out to be a medium for finding dating partners for some people. This study was conducted to determine the self-disclosure process carried out by users of the HAGO online game application in finding dating partners. Researchers applied the Social Penetration Theory by Alman and Taylor. There are 4 stages described in the Social Penetration Theory to achieve intimacy, namely the orientation stage, exploratory affective stage, affective exchange stage and stable exchange stage. This was a qualitative study using a case study method. Researchers took 4 informants who were users of the HAGO online game application who had or were dating and had a relationship with someone he knew through the HAGO online game application. The result of this study showed that self-disclosure process carried out by the informants was in accordance with the stages in the social penetration theory. Informants sequentially went through the self-disclosure stage from the orientation stage until the stable exchange stage.
Beyond GnRH, LH and FSH: the role of kisspeptin on hypothalalmic-pituitary gonadal (HPG) axis pathology and diagnostic consideration
Authors: Sikandar Hayat Khan  , Nayyer Chaudhry
Published: March 2021

Kisspeptin as a neuropeptide was established initially as regulator GnRH pulse frequency and intensity. Over time it was recognized that the interaction are mediated through a specific receptor GPR54, which has also been found throughout the hypothalamic-pituitary-gonadal (HPG) axis. Further insights into the mechanisms leading to triggering of kisspeptin were identified to be both negative and positive feedbacks from gonadal steroids along with various internal metabolic alterations and environmental triggers in the shape of diet and lifestyle. More so it was identified that these Kisspeptin/GPR54 receptor interaction was also influenced by endocannabinoid (eCB) system, GABA-ergic neuronal outputs (GABA) and other chemical agents. The most influencing neuronal inputs modifying the release of kisspeptin were identified as group of neurons termed “KNDy” in the ARC nuclei. Based upon these discoveries, scientist attempted to evaluate kisspeptin as diagnostic marker for various diseases including precocious puberty, puberty confirmation, hypogonadism, infertility and polycystic ovarian

Prediction of mild Steel weld properties using artificial neural network and regression analysis
Authors: Achebo Jacob , Eki Martins
Published: March 2021

Safety hazards resulting from structural material failure occur mostly in less developed countries where material standard specifications are not strictly adhered to, due to failure of government policy implementation. These hazards often result in loss of life. Failures tend to occur at welded joints, and various research institutions are making attempts to prevent such failures by developing new methods that could predict and improve welded joint qualities. The concern goes beyond safety, but also encompasses economic and other similar long term considerations. In this study, experimental methods were used to obtain the Bead Height (BH), Ultimate Tensile Strength (UTS) and Brinell Hardness Number (BHN) of mild steel welded joints. Thereafter, the artificial neural network (ANN), and Regression analysis methods were applied to predict the corresponding values of the BH, UTS, and BHN. The resulting performance of these two predictive methods was compared side by side to determine which one of the two methods better predicted these quality properties. This comparative analysis was carried out by comparing the percentage error of ANN to that of the Regression analysis. From the results obtained, it was found that for the bead height, Regression analysis method produced a total of 1.72% error. For UTS, ANN method produced a total of 63.31% error whereas Regression analysis produced a total of 0.39% and for BHN, ANN method produced a total of 353.86% error whereas, Regression analysis method produced a total of 2.58% error. The results shows that overall, regression analysis method predicted the properties better. Also, the effect of the process parameters on the weld properties were investigated. In this study, a step by step method is applied.
Comparative analysis of the repellency activity of single compounds and the synthetic blends of semiochemicals from Aframomum melegueta (R.schum) and Dennittia tripetala (Bak.F) against Rhizopertha dominica in Calabar, Nigeria
Authors: Ugbe Lawrence
Published: March 2021

Bioassay experiments were carried out in Calabar to compare the repellency activity of single compounds and the synthetic blends of Semiochemicals extracted from Afromomum melegueta and Dennittia tripetala. The aim of the experiment was to determine the efficacy of single compounds and the synthetic blends in suppressing the reproductive potential and adult emergence of Rhizopertha dominica, (Fabricius), a primary pest of stored cassava pellets and cereal grains in Sub-Saharan Africa. Insect culture of the adult R. dominica was set up in the laboratory at Federal College of Education Obudu to obtain fresh insects for the bioassay experiments. Dried seeds of A. melegueta (R. Schum) and D. tripetala (Baker f.) Schatz were procured from the main market in Obudu for the purpose of the research work. 100g each of the dried fruits of the spice plants were pounded separately with the laboratory pestle and mortar for the extraction of the essential oils (EOs). The oils extracted were tested for toxicity and reproductive potential deterrence against R. dominica. The chemical constituents of the essential oils were isolated, identified and tested against R. dominica. Synthetic blends of individual compounds were prepared based on their natural ratios and were also tested for toxicity and reproductive potential deterrence against the insect pests in the laboratory. The result showed that both the single compounds and the synthetic blends were toxic and repellent to the insect pest, and could significantly suppress the reproductive potential thereby inhibiting the emergence of adult insect. However, synthetic blends exhibited a stronger efficacy in their toxicity against the pest thereby providing a broad spectrum of insecticidal bioactivity against R. dominica than the single compounds. This action of the synthetic blends of extracts from the spice plants demonstrated their potential for development in stored products protection especially at the small scale resource poor farmer’s level in Nigeria.

The effect of disseminating content on social media on people's psychology is discussed in this essay. The position of social media in disseminating content with the aim of informing and supplying the public with the most up-to-date information on covid-19 problems is critical. Over the pandemic, mental wellbeing conditions have worsened as a result of the widespread dissemination of inaccurate knowledge about Covid matters, causing a slew of psychiatric challenges in community. Learning difficulties, mood swing symptoms, somatic complaints, and unnecessary fear triggered by the spread of associated facts covid-19, which seems to be quite frightening and risky. The widespread dissemination of hoaxes about Covid-19 on social media has caused widespread paranoia and terror, leading to panic shopping, which has culminated in skyrocketing costs for essential necessities due to shortages, to the point that surgical masks and hand sanitizers are no longer accessible. It not only causes erroneous beliefs, but it also causes uncertainty and anxiety, as well as affecting people's mental health.

Loss of arm and hand function is a devastating consequence of cervical spinal cord injury. Tendon transfer surgery has traditionally been used to restore key functions including elbow extension, wrist extension and grasp and pinch. The more recent development of nerve transfer surgery enables direct restoration of voluntary control of these functions. While both types of surgery are safe and effective, nerve transfer surgery results in a more open, flexible and natural hand, with more subtle control for a range of activities of daily living.

Published: March 2021

Driving while sleepy can have devastating consequences, but it is an under-recognised problem often associated with behavioural factors, medical conditions or medications. All drivers have a responsibility not to drive if sleepy and there are DVLA regulations restricting driving for patients with certain sleep disorders who are at risk of excessive sleepiness at the wheel. However, sleepiness can be difficult for patient and doctor to assess and guidelines open to interpretation. As doctors it is important we give consistent and reliable advice to patients who may be at risk when driving. This review suggests how to assess driving risk, educate patients about risk reduction, and clarifies DVLA guidelines in this area.

Mulasztás és engedetlenség: a csernobili atomkatasztrófa néhány tanulsága
Authors: Tanács János , Danka István
Published: March 2021

A csernobili atomkatasztrófa kiváltó okai – az első jelentésekben foglaltakkal ellentétben – nem az operátorok által elkövetett többrendbeli szabályszegésben keresendők, hanem tervezési és előírásbeli hiányosságok eredményeként jött létre. Ugyanakkor a Nemzetközi Atomenergia Ügynökség jelentése egyetlen területen állapított meg a baleset előidézésében szerepet játszó tényleges szabályszegést: a reaktivitási tartalékkal kapcsolatos előírás megsértése a baleset súlyosságát fokozó hozzájáruló ok szerepét játszotta. E tényleges szabályszegés kapcsán arra szeretnénk felhívni a figyelmet, hogy ez nem értelmezhető a szabályvezérelt viselkedés legalapvetőbb, azt engedelmességi kérdésnek tekintő fogalmi keretei között. A technológiai előírások követésére való hajlandóságot befolyásoló tényezők feltárása – ismeretelméleti és tudásalkalmazási relevanciája mellett – hozzájárulhat a veszélyes technológiák biztonságosabb működtetéséhez.

Published: March 2021

In 3D printing, it is important to choose the right printing parameters because they can influence the mechanical strength of the printed product. Fused Deposition Modelling (FDM)type printer was used to print specimens frompoly(lactic-acid)(PLA)fiber. Three printing temperatures, two printing rates, and two building structureswereapplied. The mechanical properties were measured by tensile and Charpy impact tests, the thermalproperties were investigated byDifferential Scanning Calorimetry(DSC)and pictures were taken from the fracturesurfaces by digital microscope. The results showed that the effect of the fiber orientation was the greatest. The temperature haslessimpact, but the changeis well demonstrated. The effect of printing rate on mechanical strength is not clear, so further studies are required. At slower rate the positive effect of temperature raisingis more visible on microscopic images.
