Authors: Dawood Yousif F. , Issa Ammar F. , Faraj Essam S.
Published: February 2021

Background: Currently, phacoemulsification is a very common cataract surgical procedure in which the lens is emulsified and aspirated from the eye through a small corneal incision.Aim: To compare early regional corneal thickness changes following phacoemulsification done by experienced surgeons versus trainee surgeons.Setting: A prospective cohort study was done at Ibn Al Haitham tertiary eye hospital in Baghdad, Iraq.Methods: The data were collected for 5 months, from 01 March 2018 until 31 July 2018. Adult patients undergoing phacoemulsification and intraocular lens surgery were prospectively evaluated and divided into two groups. Group 1 comprised those operated by experienced surgeons, whilst Group 2 patients were operated by trainee surgeons. Slit lamp examination and endothelial specular microscopy were assessed with the measurement of central corneal thickness (CCT) and peripheral corneal thickness (PCT), using Scheimpflug imaging (Pentacam).Results: There was a significant statistical difference in post-operative CCT between Groups 1 and 2, being 596.72 ± 50.69 µm compared to 631.54 ± 67.84 µm in Groups 1 and 2, respectively, with a mean difference of 34.82 µm (p = 0.000). More difference was observed in post-operative PCT (148.38 µm) as it was 734.8 ± 88.55 µm in the experienced group, compared to 883.18 ± 128.43 µm in the trainee group (p = 0.005).Conclusion: Phacoemulsification done by trainee surgeons was associated with higher CCT and PCT.
Finite element analysis of the effect of framework materials at the bone–implant interface in the all-on-four implant system
Authors: Kelkar Kasturi Chandrashekhar , Bhat Vinaya , Hegde Chethan
Published: February 2021

Background:

The “All-on-four” concept for treatment of edentulous arches incorporates four implants that are placed in between mental foramina in the mandible. The prosthetic framework is an important parameter in stress/strain concentration at the implants, prosthesis, and the underlying bone. Materials such as titanium, zirconia, and carbon fibers have been used for fabrication of framework in the past. The aim of this study was to analyze the effect of framework materials in the “All-on-four” implant system.

Materials and Methods:

Finite element three-dimensional (3D) model of edentulous mandible was simulated using a computerized tomographic scan data of an edentulous patient. Threaded implants were replicated along with the abutments using 3D modeling software and the framework was designed and simulated using material properties of titanium, zirconia, and polyetheretherketone (PEEK). Axial and nonaxial load of 200 N was applied at the abutment region of right distal implants. The computer-generated numerical values were tabulated and analysed by ANSYS software.

Results:

Principal strain, von Mises stress and micromotion were assessed in the peri-implant bone region to evaluate its stress condition. Zirconia framework showed the least stress/strain values at axial and oblique loading. Maximum strain values were seen at the PEEK framework material. Zirconia framework in all models showed the least micromotion/displacement.

Conclusion:

The stress distribution pattern at implant–bone interface was influenced by the framework material used. The framework material, loading site, and direction of forces influenced the stresses and displacement at the bone–implant interface.
In vitro antimicrobial activity of mineral trioxide aggregate, Biodentine, and calcium-enriched mixture cement against Enterococcus faecalis, Streptococcus mutans, and Candida albicans using the agar diffusion technique
Authors: Esteki Parinaz , Jahromi Maryam Zare , Tahmourespour Arezoo
Published: February 2021

Background:

This study assessed the antimicrobial activity of Biodentine, mineral trioxide aggregate (MTA), and calcium-enriched mixture (CEM) cement against Enterococcus faecalis, Streptococcus mutans, and Candida albicans.

Materials and Methods:

In this in vitro study, microbial suspensions were inoculated onto agar plates. The antimicrobial effects of MTA, Biodentine and CEM cement were assessed against E. faecalis, S. mutans, and C. albicans by the agar diffusion test. In each experimental group, 7 plates containing 3 wells were prepared and immediately filled with freshly mixed cements. Positive and negative control plates were prepared with/without the bacterial suspension, respectively. After 2 h of preincubation at room temperature, the plates were incubated at 37°C for 24 h. The diameter of growth inhibition zones was measured after 24 h. Data were analyzed using ANOVA and Tukey's test (α = 0.05).

Results:

Biodentine showed strong antimicrobial activity against all three microorganisms with an average inhibition zone of 9.10 mm. The inhibitory effect of Biodentine on E. faecalis and C. albicans was significantly superior to that of the other two cements (P < 0.05). MTA and CEM cement showed significantly higher antimicrobial activity against S. mutans (P < 0.05). The antimicrobial effects of Biodentine on S. mutans and E. faecalis were significantly greater than on C. albicans (P < 0.05).

Conclusion:

All cements revealed antimicrobial properties against the tested microbial strains. Biodentine had stronger antimicrobial effects against E. faecalis and C. albicans compared with MTA and CEM cement. Furthermore, the largest inhibition zones around all three cements belonged to S. mutans.

Authors: HajiAhmadi Maryam , Akhlaghi Najmeh , Aghajani Faezeh , Moshgelgosha Hadi , Soltanian Mahshad
Published: February 2021

Background:

Most parents believe that teething is associated with some symptoms and commonly use Internet to gain more information about the health of their children. Pediatricians can also serve as a source of information for health-related requirements of parents. This study aimed to compare the information provided by pediatricians regarding tooth eruption and the information available in Persian-language websites.

Materials and Methods:

This descriptive, analytical, cross-sectional study was performed in two phases. In the first phase, the questionnaire was designed by 85 pediatric pediatricians in Isfahan about children's dental eruption and internet resources. The second phase was the study of 22 Persian websites about children's tooth eruption using Google search engine and the keywords “tooth eruption,” “tooth eruption symptoms.” Then a checklist was prepared to evaluate the quality and completeness of the content. Data were analyzed by the Chi-square test and Fisher's exact test using SPSS (P < 0.05).

Results:

None of the retrieved websites had the health on the net code of conduct. The most common symptoms of teething reported by both pediatricians and websites included irritability, drooling, gingival tenderness, chewing tendency, decreased appetite and sleep disturbances. In non-pharmacological methods to control the symptoms related to tooth eruption in both groups, embracing the baby (P < 0.001), using soft tooth ring (P = 0.049) and chewing hard foods (0.016 P = significant. Use of oral pain medication (P = 0.01) and sedatives and medications (P = 0.04) were significant in the medication method.

Conclusion:

None of the websites reviewed had a valid source code and author. Although websites cannot replace the instructions of pediatricians regarding growth and development of children and their teething, supplementary information can be acquired from high-quality websites because there seems to be no significant difference between these two information sources regarding tooth eruption symptoms and their management.

Authors: Gajaria Pooja , Shenoy Asha , Baste Balaji , Goel Naina
Published: February 2021

Glioblastoma as second primary malignancy (SPM) has been reported after prostate cancer, meningiomas, Hodgkin's lymphoma. We report an extremely rare case of glioblastoma as SPM, occurring after remission of diffuse large B-cell lymphoma (DLBCL). Fifty-year-old male presented with loss of consciousness followed by right-sided weakness. He was treated with chemotherapy for DLBCL of the cervical lymph nodes, 5 years back. Present scans revealed well-defined intra-axial lesion in the left parietal lobe, suggestive of central nervous system (CNS) involvement by lymphoma. Left parieto-occipital craniotomy was performed and microscopic examination revealed the tumor to be Glioblastoma, WHO Grade IV. The tumor cells were positive for glial fibrillary acid protein and negative for leucocyte common antigen. He was treated by radiotherapy and temozolomide. Pathologic examination is a must for CNS lesions. Had it not been for the biopsy, the patient would have been treated as a recurrence of CNS lymphoma by chemotherapy and would have probably succumbed.
Experimental evaluation of the risk of distal embolization during endovascular clot retrieval using various techniques
Authors: Ohshima Tomotaka , Miyachi Shigeru
Published: February 2021

Background: This study was conducted to evaluate various devices and techniques for endovascular thrombectomy that can reduce the risk of intraprocedural distal embolism in a preliminary in vitro setting with different types of thrombi. Materials and Methods: Endovascular clot retrieval was performed in a vascular model with collateral circulation. White and red thrombi were prepared using whole blood collected from a pig. A Direct Aspiration First Pass Technique (ADAPT), simple stentretrieving with and without proximal flow arrest by a guiding balloon (SR [B+] and SR [B±]), the AspirationRetriever Technique for Stroke (ARTS), and A stentretrieving into an Aspiration catheter with Proximal balloon (ASAP) were performed three times, respectively. The saline samples that were collected at the distal side during each procedure were examined using a particle counter. The particles were counted and categorized into three groups based on size (100 μm). Results: SR (B−) and SR (B+) could not achieve complete retrieval of the clot, especially using the white thrombus. ASAP was the only method that was able to retrieve the clots in all attempts. In both clot types, SR (B−), SR (B+), and ARTS, which involved a temporary flow restoration through stent deployment, demonstrated the migration of a greater number of particles measuring >100 μm in size than that shown by ADAPT and ASAP. Conclusions: ASAP was the safest method in terms of intraprocedural clot migration among the five methods evaluated in this study. Temporary flow restoration through stent deployment may affect the dangerous distal clot migration.
Are thinking machines breaking new frontiers in neuro-oncology? A narrative review on the emerging role of machine learning in neuro-oncological practice
Authors: Hussain Mustafa , Shabbir Ainsia , Bakhshi Saqib , Shamim Muhammad
Published: February 2021

Medical science in general and oncology in particular are dynamic, rapidly evolving subjects. Brain and spine tumors, whether primary or secondary, constitute a significant number of cases in any oncological practice. With the rapid influx of data in all aspects of neuro-oncological care, it is almost impossible for practicing clinicians to remain abreast with the current trends, or to synthesize the available data for it to be maximally beneficial for their patients. Machine-learning (ML) tools are fast gaining acceptance as an alternative to conventional reliance on online data. ML uses artificial intelligence to provide a computer algorithm-based information to clinicians. Different ML models have been proposed in the literature with a variable degree of precision and database requirements. ML can potentially solve the aforementioned problems for practicing clinicians by not just extracting and analyzing useful data, by minimizing or eliminating certain potential areas of human error, by creating patient-specific treatment plans, and also by predicting outcomes with reasonable accuracy. Current information on ML in neuro-oncology is scattered, and this literature review is an attempt to consolidate it and provide recent updates.
Proximal junctional kyphosis after pediatric angular kyphotic deformity correction: Are we missing something?
Authors: Mallepally Abhinandan , Mahajan Rajat , Marathe Nandan , Nanda Ankur , Rustagi Tarush , Chhabra Harvinder
Published: February 2021

Purpose: Corrective maneuvers in an angular kyphotic deformity have its own problems including early complications such as neurological deficit and late complications such as proximal junctional kyphosis (PJK) and proximal junctional failure (PJF). This article discusses the probable mechanisms, leading to PJK in pediatric severe angular kyphotic deformities and preventive strategies for the same. We will also assess natural course of untreated PJK and its devastating consequences. Materials and Methods: Three patients, two 13-year males presented with progressive, painless thoracolumbar kyphoscoliotic deformity, with segmental kyphosis 100° and 140° and scoliosis of 33° and 78°, respectively, and one 14-year-old female presented with angular kyphotic deformity of 60° with apex at D11-12 level. Results: Posterior vertebral column resection with segmental deformity correction with good coronal and sagittal balance was done. In the follow-up, PJF was seen. Second surgery was done with the extension of instrumentation to D4 along with deformity correction in both the male patients. The female patient did not opt for a revision surgery, and we are following the natural history of this case. Conclusion: In severe thoracolumbar angular kyphotic deformities with normal or negative sagittal balance, it might be a safer option to select the sagittal stable vertebra as upper instrumented vertebra based on the C2 plumb line on the preoperative standing lateral radiographs. However, a study with a larger sample size is needed to validate our hypothesis.
A rare case report of flexion teardrop cervical fracture with blunt vertebral artery injury leading to stroke
Authors: Srivastava Sudhir , Raj Aditya , Bhosale Sunil , Marathe Nandan , Gaddikeri Manojkumar
Published: February 2021

Non penetrating trauma to vertebral artery is a known complication in craniovertebral trauma. They are mainly reported with facet dislocations or injuries involving the foramen transversarium. Such a type of injury is rarely seen with flexion injuries. We report such a case leading to cerebellar stroke in a young male presenting to us with hemiparesis. A 43-year-old male presented to us 1 month post trauma after a motor vehicular accident with complaint of weakness of right half of the body since the trauma. He suffered blunt trauma to head and neck and complained of a flail right upper limb since trauma and weakness of the right lower limb which had partly improved. He was conservatively managed elsewhere. Radiographic investigations revealed complete occlusion of the right vertebral injury above the level of 6th cervical vertebra and flexion teardrop fracture of 5th cervical vertebra. He was managed conservatively for the vertebral artery injury (VAI) and corpectomy of C5 vertebra with anterior cervical plating and fusion. Such a rare type of injury can present with unexplained neurodeficit which needs appropriate radiological investigations for diagnosis before ascribing the cause to cord trauma. Hence, all high velocity motor vehicular accidents with associated fractures and neurodeficit should be screened for blunt VAIs.

Published: February 2021

Background: Electrolyte imbalance and acute diabetes insipidus (DI) are the most common complications in patients undergoing craniopharyngioma excision. Data are sparse regarding the choice of fluid in these patients. We compared the effects of balanced salt solution and 0.45% saline infused perioperatively on serum osmolality and serum sodium levels in these patients. Methodology: A prospective randomized double-blinded study was conducted in 30 patients undergoing transcranial excision of craniopharyngioma. The patients received either balanced salt solution or 0.45% sodium chloride solution perioperatively till they were allowed orally. Serum and urine osmolality, serum and urine sodium, urine specific gravity, and total dose of desmopressin required to treat DI were measured in the perioperative period. Results: Demographic data were comparable. We observed that there was significantly higher serum osmolality in the intraoperative period at 2nd h (P = 0.04), 3rd h (P = 0.01), at end of the surgery (P = 0.034) and on postoperative day 0 (POD 0) with P = 0.03 in patients receiving balanced salt solution. We also observed that the difference in serum sodium levels were significantly higher in patients receiving balanced salt solution as compared to those receiving 0.45% sodium chloride solution intraoperatively, at 3rd h (P = 0.02) and at the end of surgery (P = 0.04) although the values were comparable in both the groups as measured on POD 0, 1 and 2. Conclusion: 0.45% sodium chloride solution has better effect on serum osmolality than balanced salt solution in patients undergoing transcranial resection of craniopharyngioma.

Authors: Singh Anamika , Kumar Raj , Singh Naresh , Yadav Ramakant , Kumar Arushi
Published: February 2021

Background: Traumatic brain injuries (TBIs) are the leading cause of morbidity, mortality, disability, and socioeconomic losses globally, but of more concern, in India and other developing countries. The Mini mental state examination (MMSE) and clock drawing test (CDT) are the two mostly adapted methods for cognitive impairment screening. Therefore, it is necessary to establish a robust evaluation system exclusively for post-TBI cognitive impairment. Materials and Methods: One hundred and thirty-four cases treated previously at the health facility for TBIs were evaluated for cognitive functions during the follow-up period ranging from 3 weeks to 6 months in the out-patient department. All cases underwent mini-mental score examination (MMSE) and CDT to assess their cognitive performances. The data were analyzed statistically using Chi-square and ANOVA tests of significance. Results: Statistically significant association (P < 0.001) between the cognitive status of patients on the basis of overall MMSE score and the site of brain injury was observed. It was noted that 76 (56.7%) of the cases had cognitive impairment (MMSE score <24) with majority 44 (32.8%) patients having frontal lobe injuries, followed by 14 (10.1%) having brain injuries in the temporal lobe. On the other hand, using CDT score, it was observed that 102 (76.1%) of the cases had cognitive impairment (CDT score <5) with the majority 49 (36.6%) cases having frontal lobe injury followed by 19 (14.2%) having brain injury in the parietal lobe. Conclusion: The CDT was able to access cognitive function disruption in those patients, in whom the mini-mental score examination was not able to assess the same, and this difference in detection capabilities of both the tests was statistically found significant.

Published: February 2021

Lytic lesions in adult spine are a common manifestation of aggressive disease such as primary bone tumor, metastasis, myeloma, or infectious pathology. Xanthoma arising in the spine with purely intraosseous component is an extremely rare occurrence with only six cases reported in the adult population, none in the cervical region. We report the first case of primary xanthoma of the cervical spine in a 50-year-old male solely confined to osseous compartment. The imaging mimics of lytic lesion with expansile mass in adult spine are reiterated.

Published: February 2021

Segmental zoster paresis is characterized by focal motor weakness affecting the myotome corresponding to the dermatomal distribution of the rash. Clinically, it presents as pseudohernia when it involves abdominal wall muscles. We report three cases of segmental zoster paresis presenting as pseudohernia of abdominal wall. All patients developed asymptomatic bulge in anterolateral side of abdomen between 10 and 15 days after appearance of vesicles. All patients developed post-herpetic neuralgia. One patient developed pseudo-obstruction of colon due to visceral involvement. Segmental zoster paresis of lower thoracic spinal segment often goes unnoticed due to its asymptomatic nature.

Published: February 2021

An 18-year-old male presented with an erythematous plaque on the left side of face and neck since 4 years. The lesion was devoid of hair, had follicular prominences, and showed increased localized sweating. Histopathology revealed an increased number of eccrine glands in the myxoid stroma with multiple vascular elements in the dermis, favoring the diagnosis of eccrine angiomatous hamartoma. This case illustrates a relatively uncommon clinical presentation of eccrine angiomatous hamartoma as a hairless, hyperhidrotic plaque in the head and neck region.

Authors: Bonifaz Alexandro , Tirado-Sánchez Andrés , Vazquez-Gonzalez Denisse , Araiza Javier , Hernández-Castro Rigoberto
Published: February 2021

Context:

Mycetoma is a chronic, granulomatous disease caused by fungi (eumycetoma) or aerobic filamentous actinomycetes (actinomycetoma). Actinomadura madurae is one of the most frequent actinomycetes.

Aim:

The study aims to provide an update on clinical, diagnostic, therapeutic, and outcome data for patients with actinomycetoma in a single center in Mexico.

Settings and Design:

This was a retrospective study of 47 cases diagnosed with actinomycetoma.

Subjects and Methods:

The cases were selected from a total of 536 mycetoma obtained during 35 years (from 1985 to 2019). Clinical data were retrieved from the clinical records of our department. Microbiological data were obtained from our Mycology laboratory.

Statistical Analysis:

Frequencies and percentages were used for categorical variables. Normality was determined with the Kolmogorov–Smirnov test. We used means and medians to describe the variables.

Results:

Forty-seven patients with actinomycetoma were included; female:male ratio 1.9:1; median age 38 years. The foot was the most affected region in 76.5% of cases. The bone invasion was observed in 89%. The time between symptoms onset and diagnosis was 5.5 years. Grain detection by direct examination was positive in 95% of cases. The most commonly used, as well as the most effective treatment scheme was streptomycin + sulfamethoxazole-trimethoprim with dapsone. Sixty-three percent (30 patients) achieved clinical and mycological cure, and 10.6% (5 patients) had treatment failure.

Conclusions:

We highlight the importance of designing therapeutic strategies to standardize treatments and gain more experience to improve the care of these patients.

Published: February 2021

Three cases of giant diaphragmatic hernia were reported in our study. Computed tomography (CT) scan showed multiple organ migration into the chest. The clinical presentation included bowel obstruction, dyspnea, or chest pain. The operations were performed initially by laparoscopy to reduce the hernia content. The defect was closed with a nonabsorbable suture and was reinforced with a synthetic mesh. All patients recovered well without any serious complications. The symptom improved significantly after surgery. Postoperative CT scan showed normal anatomy. There was no evidence of recurrence within 6 months after the operation.
A novel technique using endoscopic band ligation for removal of long-stalked (>10 mm) pedunculated colon polyps
Authors: Choi Hyun Ho , Kim Chang Whan , Kim Hyung-Keun , Kim Sang Woo , Han Sok Won , Seo Kyung Jin , Chae Hiun-Suk
Published: February 2021

Background:

Endoscopic removal of large and thick-stalked pedunculated colonic polyps, often leads to massive hemorrhage. Several techniques to minimize this complication have not been widely adopted due to some caveats. In order to prevent postpolypectomy bleeding, we invented a novel technique to dissect long-stalked pedunculated colonic polyps using endoscopic band ligation (EBL) by laterally approaching the stalk.

Methods:

In this prospective single-center study, 17 pedunculated polyps in 15 patients were removed between April 2012 and January 2016. We targeted pedunculated polyps with a long stalk length (>10 mm) and a large head (>10 mm) located in the distal colon. After identifying lesions with a colonoscope, we reapproached the middle part of the stalk of the targeted polyp with an EBL-equipped gastroscope to ligate it. Snare polypectomy was performed just above the ligation site of the stalk.

Results:

EBL-assisted polypectomy removed all of the lesions successfully, which were confirmed pathologically. There was little technical difficulty associated with the endoscopic procedures, regardless of polyp size and stalk thickness, except for one case with a very large polyp that impeded the visualization of the ligation site. We observed a positive correlation between procedure time and the diameter of the head (spearman ρ = 0.52, P = 0.034). After dissection of the polyp, the EBL bands remained fastened to the dissected stalks in all cases. There was no complication associated with polypectomy for 1 month.

Conclusion:

EBL-assisted polypectomy is an easy, safe, and effective technique to remove long-stalked pedunculated colonic polyps without postpolypectomy bleeding.
Calculating the Strength of Rhetorical Arguments in Persuasive Negotiation Dialogues
Authors: Morveli Espinoza Mariela
Published: February 2021

Rhetorical arguments are used in negotiation dialogues when a proponent agent tries to persuade his opponent to accept a proposal more readily. When more than one argument is generated, the proponent must compare them in order to select the most adequate for his interests. A way of comparing them is by means of their strength values. Related work propose a calculation based only on the components of the rhetorical arguments, i.e., the importance of the opponent's goal and the certainty level of the beliefs that make up the argument. This work aims to propose a model for the calculation of the strength of rhetorical arguments, which is inspired on the pre-conditions of credibility and preferability stated by Guerini and Castelfranchi. Thus, we suggest the use of two new criteria to the strength calculation: the credibility of the proponent and the status of the opponent's goal in the goal processing cycle. The model is empirically evaluated and the results demonstrate that the proposed model is more efficient than previous works in terms of number of exchanged arguments and number of reached agreements.

O’nyong-nyong virus (ONNV) is a little-known arbovirus causing intermittent, yet explosive, outbreaks in Africa. It is closely related to chikungunya virus, an emerging infectious disease. O’nyong-nyong virus causes a self-limited illness characterized by bilateral polyarthritis, rash, low-grade fever, and lymphadenopathy. In 1959, an extensive outbreak of ONNV occurred in East Africa, and decades later, another large outbreak was documented in Uganda in 1996. Limited evidence for interepidemic transmission is available, although serologic studies indicate a high prevalence of exposure. 1,045 febrile child participants in western and coastal Kenya were tested for the presence of ONNV using a multiplexed real-time reverse transcriptase–PCR assay. More than half of the participants had malaria parasitemia, and there was no evidence of active ONNV viremia in these participants. Further work is required to better understand the interepidemic circulation of ONNV and to reconcile evidence of high serologic exposure to ONNV among individuals in East Africa.

Published: February 2021

With the rapid development of vehicle communication and the goal of self-driving vehicle, research in this area is still ongoing, as car companies aspire for more studies and effective communication methods between vehicles. In this research, we have developed an intelligent, innovative and fully integrated multi agent model, which is used for vehicle-to-vehicle communications. The developed model is supported by an intelligent system based on a Nonlinear External Neural Network (NARX) and signal estimation theory. The system is built using real vehicles sensors, Arduino, GSM and RF technologies. The system is tested by applying different scenarios and observing vehicle behaviors. The results show that the smart system is able to make the appropriate decision based on both the vehicle's current condition and sensor readings. The developed system is able to operate effectively in a noisy environment in an excellent manner.
The Voice Transcription Technique: Use of Voice Recognition Software to Transcribe Digital Interview Data in Qualitative Research
Authors: Matheson Jennifer
Published: February 2021

Transcribing interview data is a time-consuming task that most qualitative researchers dislike. Transcribing is even more difficult for people with physical limitations because traditional transcribing requires manual dexterity and the ability to sit at a computer for long stretches of time. Researchers have begun to explore using an automated transcription process using digital recordings and voice recognition software (VRS). While VRS has improved in recent years, it is not yet available to the general public in a format that can recognize more than one recorded voice. This article outlines a strategy used to circumvent this problem and improve the speed and ease of transcription. The equipment and the Voice Transcription Technique used are outlined, as well as suggestions for future technological advances in transcription.

The False Witness: Artistic Research on Stage
Authors: Simhoni Orit
Published: February 2021

Sharing research findings with others is a fundamental concern of researchers. Qualitative research results may be disseminated in conventional (e.g., scholarly text or presentation) or innovative (e.g., art, drama, or poetry) forms. Given that researchers should select the best form of presentation of their work, it is worthwhile to explore creative options. One such option is theatrical performance. The purpose of this study is to describe one playwright’s experience in creating a research- based drama, The False Witness. While focusing on the process of research-based drama, this article is intended to inform researchers and artists about the potential of a research -based theatrical production to re- present social research material--and to tell a story in a way that can transform social consciousness.

This study examines meanings and processes associated with religious practices of prayer, building faith, and forgiving through in-depth, qualitative interviews with six highly religious Roman Catholic families with children. Families were interviewed using a narrative approach that asked participants to share experiences and challenges related to faith and family life. Three primary themes in the interviews included: (a) prayer helps piece the puzzle together, (b) faith builds a foundation, and (c) forgiveness allows unity to flourish.
Palinode: The Heteronormative Re/production of Transsexual
Authors: Kaufman Jodi
Published: February 2021

This project began at the intersection of several conversations: Recently Jay Prosser (2005) wrote a palinode of his analysis of Del Lagrace's photograph of the genitals of a female -to-male transsexual. Recanting his original reading of the photograph as a referent directly linked to "male," Prosser re-read the photograph, suggesting "the referent [is] unsuturable with the signifier," in other words concluding that transsexuality...is...irreconcilable...within gender representation" (p. 176). This idea of a palinode caught my attention. How could I re-read my data to realize what was lost in the original, to find that which exceeded the bounds of signification so I might further glimpse the real (Prosser, 2005)? Concurrently, I was reading Pink's (2004) call to use hypertext as a means to critically reflect on the way arguments are constructed, and MacDougall's (2006) discussion on how the mode of representation influences meaning. Swimming with these thoughts, I began to use writing in and through Storyspace, a self-publishing hypertext program, as a method of inquiry (Richardson & St. Pierre, 2005) to write this palinode.
Why Video? How Technology Advances Method
Authors: Downing Martin
Published: February 2021

This paper reports on the use of video to enhance qualitative research. Advances in technology have improved our ability to capture lived experiences through visual means. I reflect on my previous work with individuals living with HIV/AIDS, the results of which are described in another paper, to evaluate the effectiveness of video as a medium that not only collects data, but also produces knowledge. I have provided strategies for confronting specific technological barriers and concerns in research. I made sure to consider my own role within this research, and have chosen to share the personal insights and revelations that occurred in light of using this visual method.

Advances in technology provide researchers with increased opportunities to locate and conduct research with populations that have historically been inaccessible. This manuscript de scribes the development of private, voluntary web-based groups, and the process for using web cameras to conduct individual web-based interviews as a method of data collection in qualitative research. Also contained within are detailed steps for utilizing each of these technological innovations as well an exploration of the ethical issues related to using technology to enhance the research experience with members of hidden populations, using the GLBT population as a referent group.
Types of Knowledge, Forms of Practice

Published: February 2021

This study was designed to explore the way that us e of theory influenced a social worker’s conceptualization of a simulated case. The participant in this case study was a woman employed in child welfare, who holds an MSW. She was chosen because her response in a larger study represented a deviant case. Data analysis included both thematic analysis and an analysis of a written report based on ideas taken from institutional ethnography. The authors use this case example to illustrate the ways that one’s understanding of theory may impact social work practice.

Authors:   PAF KIET, Malik Kaenat
Published: February 2021

In today’s competitive world, it has become difficult for organizations to manage and attract a talented workforce. In view of this most firms are using employer branding strategies to attract and retain the employees. In view of its importance, we have developed a new conceptual framework that has five direct hypotheses and three indirect hypotheses. We have collected data from 400 faculty members of the leading business institutes of Karachi. The questionnaire was adapted from the earlier established scales. Smart PLS 3.2 was used for data analysis. This study found that it is important for firms to forego old HR practices and adopt employer branding. The HR manager in the present era required to spend considerable time building the image of the firms by interacting with all the stakeholders of the firms. A strong brand image is not only attractive to new employees, but it also enhances the job satisfaction level of the existing employees. Employers branding promotes a conducive environment due to which employees’ satisfaction level increases but they also develop a sustainable relationship with firms. Thus both the employees and employers benefit from it.

This study examined the growth response of black tiger shrimp, Penaeus monodon, reared in indoor cement ponds fed at variable daily feeding frequencies. Five hundred healthy shrimp (1.26±0.37 g initial weight) were stocked in 12 cement ponds (5.5×2.5×1.5m). Three ponds in each group were assigned to four different feeding frequency i.e., two, three, four and six times/day designated as FF1, FF2, FF3 and FF4, respectively. Artificial diet (40% fishmeal protein) was used to feed at eight percent of total shrimp body weight per day for a total period of 56 days. The shrimp length and weight were measured fortnightly and the feeding rate was adjusted according to the new weight. At the end of the trial, all shrimp remained healthy and active with the survival rate of 70-85%. The specific growth rate (SGR) were the highest in groups FF3 (4.21±0.53) and FF4 (4.23±1.04), which were significantly higher than those in FF1 (3.82±0.49) and FF2 (4.02±1.03) groups. Whole body proximate composition (protein, ash, moisture and lipid) remained similar in all the treatment groups. It could be concluded that the black tiger shrimp, P. monodon, would be grown in indoor cement ponds effectively by feeding four times day-1 to achieve significantly better growth.
