Published: July 2023

The authors develop a teacher-parent partnership-based learning system and apply it to investigate through experimentation. Samples were taken by multistage random sampling and placed in two groups. The experiment group involved 56 elementary schools (899 students and 899 parents), and the control group (without using the system) was fifty-two schools (541 students). Describing student competency data using descriptive statistics and competence in the experimental group was tested through one-way ANOVA, Sig. = .05. The students' competence with the partnership-based learning system was better. Student competence in the group of parents' work type, educational level, and economic level appears to vary. The kind of parents' work interacted with parents' academic rank and parents' financial status levels. In conclusion, various parents' backgrounds play a crucial role in partnership learning through internet-based learning systems, which must be considered in learning system use.

Published: July 2023

Dysprosium oxide nanoparticles (Dy2O3-nanoparticles) have been extensively used in many different fields of technologies. In addition, with a proper synthesis modification, Dy2O3-nanoparticles are promising materials not only for industry purposes, but also for biomedical applications, for instance, through polyethyleneglycol (PEG) attachment as a template on nanoparticles. This study focuses on the optimization of hydrothermal synthesis of Dy2O3-nanoparticles using Response Surface Methodology – Box-Behnken experimental design (RSM-BBD). The influences of the volume and concentration of PEG-template to the size diameter of nanoparticles were also studied. The crystal structure and surface morphology Dy2O3-nanoparticles with PEG-template modification were characterized using Tabletop Scanning Electron Microscopy (TSEM) coupled with Energy Dispersive X-Rays (SEM-EDX) and X-Rays Diffraction (XRD). Dy2O3-nanoparticles were prepared by using hydrothermal synthesis method with PEG-template attachment on the nanoparticles. PEG as a template will create the uniform shapes and prevent the agglomeration of the nanoparticles. For further biomedical applications, it also helps to enhance the biocompatibility of nanoparticles. The optimization of influence parameters on the hydrothermal synthesis of Dy2O3-nanoparticles, (e.g. mass ratio precursor (PEG and Dy2O3), temperature, and time) were investigated using RSM-BBD. The optimum conditions were 15 g PEG and 0.45 g Dy2O3 at 200°C for 7 h resulting in the highest amount of Dy2O3-nanoparticles products. SEM image results show spherical and nanowires shapes of Dy2O3-nanoparticles produced with the average size diameter of 10.1 nm as the smallest size of nanoparticles. In addition, XRD-patterns indicates the typical cubic structure of Dy2O3-nanoparticles with the estimation crystal size of 45.47 nm.

The emergence of two-dimensional (2D) hybrid metal-halide perovskites has garnered significant attentions for optoelectronic devices and light-emitting applications. Since the toxicity of lead-based perovskites could potentially be harmful to the environment, several works have attempted to change the active metal to tin (Sn). Here, we investigate the characterization of (PEA)2SnBrxI4-x mixed halide perovskites using X-ray fluorescence (XRF), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. Qualitative XRF analysis suggests the presence of tin, bromine and iodine emissions under the mid-Z and high-Z ranges. In mid-Z range, Br-Kα peak appeared on 11.96 keV and Br-Kβ was detected on 13.3 keV. Meanwhile Sn-Kα, I-Kα, I-Kβ1, and I-Kβ2 peaks were detected in high-Z range on 25.24 keV, 28.6 keV, 32.35 keV and 33.11 keV, respectively. Thus, the elemental composition of mixed halide components exhibits an indicative control that bromine-rich or iodine-rich can be synthesized via rational chemical design. XRD pattern display a systematic progression at the peak 5.18° (corresponds to (002) plane), which unambiguously demonstrated the feasibility to tune halide composition in tin-based hybrid perovskite. It also confirms that (2D) hybrid metal-halide with tunable halide have identical structure for both bromine-rich and iodine-rich composition. Furthermore, the 2θ peaks slightly shifted to lower angle with increasing bromine composition. The presence of C−I bonding on ~500 cm-1 and C-Br bond on ~600 cm-1 in FTIR spectra highlights the functional group of organic cations. These experimental results promote a foundation to implement compositional engineering on 2D-tin mixed-halide perovskites for optoelectronics and scintillators.

Published: July 2023

The systematic study of human locomotion known as gait analysis can be applied in various contexts, including athletics, rehabilitation, and clinical diagnoses. However, the present gait analysis methods have several limitations that make them inappropriate for individual use, such as the fact that they are expensive, non-portable, need a significant amount of time to set up, and require additional time for post-processing. This study aims to investigate and develop a gait analysis system to measure the vertical ground reaction forces. The measurement instrument qualities of being flexible, portable, and comfortable are essential to the design of wearable sensors. The device was calibrated using a universal testing machine (Force plate device). In addition, this study used flexible force sensors for detecting vGRF. The result shows the device works with high efficiency and accuracy in measurement when calculating the values of ground reaction force compared with the values ​​ of reaction force measured by the university testing machines.

Authors: Shayan Amin , Berjis Nezammedin , Hashemi Sayed Mostafa
Published: July 2023

Background:

Tonsillectomy, one of the most common otolaryngology surgeries, often results in postoperative complications such as pain and bleeding. Currently, there is no consensus on postoperative pain management. This study aimed to determine the efficacy of oral prednisolone on postoperative pain after tonsillectomy with sutures.

Materials and Methods:

This pilot, double-blind, randomized clinical trial was conducted at two tertiary care centers affiliated with Isfahan University of Medical Sciences. Patients who underwent tonsillectomy with sutures were included. Participants were randomly divided into experimental and control groups. In the experimental group, patients received oral prednisolone in addition to acetaminophen; in the control group, patients received acetaminophen and a placebo. Post-operative pain was evaluated by a visual analog scale daily for ten days.

Results:

Initially, 60 patients were enrolled in the study; however, four were excluded due to non-attendance at follow-up visits. The groups were similar in terms of age and sex (both P values >0.05). In the study, postoperative pain from 1st day to the 10th day was lower in the experimental group than in the control group (P value <0.05).

Conclusion:

Numerous studies have been conducted on the effect of intravenous corticosteroids on this pain. However, there is no consensus on the analgesic role of oral corticosteroids for post-tonsillectomy pain. The present study showed that oral prednisolone is effective on post-operative pain compared to a placebo.

Authors: Dutta Subham , Kumar R. Mahesh , Kumar K. R. Ashok , Marimallappa T. R. , Pal Supriyo , Rao Keerthana
Published: July 2023

Introduction:

Disimpaction is one of the most common operations done by oral and maxillofacial surgeons around the world. Ketamine is a well-known general anaesthetic and short-acting intraoperative analgesic. The aim of this study was to measure the efficacy of anaesthesia using combined treatment with local anaesthetic plus a subanaesthetic dose of ketamine and local anaesthetic alone in bilaterally impacted mandibular third molar surgery.

Methods and Materials:

A total of 24 patients who consented were taken up for a split-mouth study. In the control group, surgical extraction of the impacted lower third molar was done using local anaesthesia (lignocaine 2% with 1:80,000 adrenaline) only, and in the study group, local anaesthesia with ketamine extraction was done using ketamine (0.2 mg/kg) along with local anaesthesia (LA). The time of onset and the duration of anaesthesia intraoperatively were recorded using a digital stopwatch. The depth of anaesthesia was noted on the 10th, 30th and 60th min. After extraction, the post-operative pain on the first, fourth, eighth and 12th hour was evaluated using a Visual Analogue Scale (VAS) score rating of 1–10. The pulse was also noted and compared for any differences in either of the groups.

Results:

A statistically significant (P < 0.005) difference in result was obtained for the onset, duration, depth and pain score after surgical extraction in both the evaluated groups. The pain index score by the ketamine group was significantly low as compared to the local anaesthesia-only group. Intraoperative onset, duration and depth of anaesthesia obtained had a significant difference.

Discussion:

Ketamine can be used as a viable option for surgical third molar extractions with reduced discomfort and post-operative pain.

Published: July 2023

Introduction:

Traditionally, sutures have been widely used to close intraoral wounds. Various alternatives have been developed amongst which newer tissue adhesives such as N-butyl-2-cyanoacrylate having accepted clinical properties are gaining popularity. The primary purpose of the present study is to evaluate the efficacy of N-butyl-2-cyanoacrylate for intraoral attached mucosal wound closure following alveoloplasty.

Materials and Methods:

In this prospective split-mouth study, 25 patients requiring alveoloplasty in either maxillary or mandibular arch bilaterally with a total of 50 sites were divided into two equal groups, namely silk suture (Group 1) and cyanoacrylate (Group 2). Each patient was evaluated on the first, third, seventh, 14th and 21st post-operative days. Parameters evaluated were time taken to close incision and to achieve haemostasis, pain, oedema, post-operative wound healing, patient discomfort and possible complications.

Results:

Time taken to close incision, time taken to achieve haemostasis, post-operative pain and oedema were found to be less in Group 2. Wound healing too was found to be better in Group 2. There was one case of adhesive peel off on the first post-operative day which was managed by reapplying the tissue adhesive. The incidence of wound dehiscence and wound infection was observed more in Group 1 on the third post-operative day. Suture breakage (16%) and adhesive dislodgement (8%) were reported on the seventh post-operative day.

Discussion:

The use of cyanoacrylates’ inherent benefits, such as improved wound seal off in attached mucosa, quick polymerisation and bacteriostatic characteristics can be beneficial when performing minor oral surgical procedures on elderly, young and mentally challenged patients.

Authors: Fawzy Samah M. , Al-Tawab Mohammed S.A. , Ismail Zafer F. , Ebeid Weam M.A.
Published: July 2023

Aim

We aimed to compare the anatomical and visual response of newly diagnosed choroidal neovascularization (CNV) secondary to pathological myopia or age-related macular degeneration with relatively poor initial vision to treatment with three intravitreal injections of ranibizumab.

Patients and methods

This prospective, comparative study included 29 eyes of 29 patients newly diagnosed with subfoveal active CNV, either secondary to age-related macular degeneration (AMD-CNV, 15 eyes) or to pathological myopia, that is, myopic CNV (MCNV, 14 eyes). All patients had an initial best-corrected visual acuity (BCVA) equal to or worse than 1.00 Log Mar. Patients received three intravitreal injections of 0.50 mg ranibizumab on a monthly basis. Patients were evaluated before injections and one month after each injection for BCVA and optical coherence tomography-measured retinal parameters: central macular thickness, total volume, and average thickness (AT). Amsler's chart was used to detect scotomas and metamorphopsias.

Results

One month after the three injections, a significant improvement was noted in the two groups in central macular thickness, total volume, and AT. The improvement was significantly better in AT of the AMD group. The mean BCVA improved significantly in the AMD group only as patients either improved or remained stationary, whereas in the MCNV group, 21% of patients deteriorated, which affected the significance of the overall mean of improvement (P=0.7823); the difference in the overall mean was insignificant. Despite that, almost half of the patients in each group had their visual acuity improved by an average of 9.5 letters in AMD and 10.7 in MCNV.

Conclusion

Naïve AMD-CNV and MCNV of initially poor VA can get significant improvement in all optical coherence tomography-measured retinal parameters following a three-injection course of ranibizumab on a monthly basis. VA improvement is more predictable in AMD, as no patients deteriorated after the injections, yet the overall difference in VA improvement between groups was insignificant.

Authors: Kamhawy Amira S.M. , Salem Osama A. , El Zankalony Yasser A. , Ebeid Ahmed A.
Published: July 2023

Background

To study the endothelial cell layer 3 months after Descemet membrane endothelial keratoplasty (DMEK) using specular microscopy to provide data about the endothelial cell density (ECD), endothelial cell loss (ECL) percentage, and changes in endothelial cell shape (hexagonality) and size [coefficient of variation (CV)] and to study the factors causing these changes in endothelial cell layer after DMEK.

Patients and methods

This study included 20 patients investigated by specular microscopy 3 months after DMEK. We discuss the postoperative ECD, factors that affect the ECD, factors that affect hexagonality and CV, visual outcome, and advantages of DMEK. The study was approved by the ethics committee of Ain Shams University.

Results

This study showed that the mean ECD postoperative was 1664.80 cells/mm2, with mean ECL of 34.67%. This cell loss increased in cases of difficult graft unfolding. Donor age and preservation time had no effect on postoperative ECD. A percentage decrease in hexagonal cells and a percentage increase in CV were noticed in cases that received grafts from donors with history of diabetes mellitus. Postoperative ECD and hexagonal cell percentage had no correlation with central corneal thickness in this study.

Conclusion

DMEK results in significant improvement of postoperatively visual acuity (VA). Advantages of DMEK like no corneal sutures, short recovery time, less cylindrical aberration, decreased incidence of graft rejection, and good visual outcome make it the best choice to treat eyes with corneal endothelial dysfunction.

Published: July 2023

Background and Aims:

Ventilator-associated pneumonia (VAP) is a nosocomial infection associated with high morbidity and mortality. This study was undertaken to monitor the trend of the demographical details, comorbid conditions, bacterial etiological agents, and their antibiogram causing VAP in adults in the year 2008, 2013 and 2018.

Material and Methods:

A retrospective study conducted at the Department of Microbiology, Hospital Infection control and Quality Control at a tertiary care teaching hospital. All the adult patients with more than 48 h of the mechanical ventilator with endotracheal intubation with Clinical Pulmonary infection Score >6 with suspicion of VAP were included in the study at a difference of 5 years, i.e., 2008, 2013, and 2018.

Results:

A total of 338 patients were included in the study, of which males accounted for more than two-third of the patients studied. Nearly 45% of the patients belonged to geriatric (>60 years) age group. The most common comorbid conditions were chronic obstructive pulmonary disease, hypertension and diabetes mellitus. Among the gram-negative isolates, Klebsiella pneumoniae, Acinetobacter species, and Pseudomonas aeruginosa were the most common. There is an emergence of resistance to most commonly administered antimicrobial agents like aminoglycosides, levofloxacin, piperacillin/tazobactum, and carbapenems during the study period.

Conclusion:

This is a ten-year study on the antibiotic resistance pattern of organisms causing VAP. As far as the authors are aware, this is the first study addressing the pattern of change in drug resistance in the organisms causing VAP over a decade. The emergence of multi-drug resistant (MDR) MDR pathogens, especially in intensive care unit (ICU), is a great concern for the intensivist and infection control physicians. Preventive measures need to be undertaken to control the spread of these pathogens to the patients in the ICU.
Ventilator-associated pneumonia

Published: July 2023

Ventilator-associated pneumonia (VAP) has traditionally been defined as pneumonia in patients with mechanical ventilation for at least 48 h. Despite advancements in critical care, VAP remains to be a complication resulting in huge financial burden to patients. The limitations to the criteria have resulted in an urge to redefine VAP by the Centers for Disease Control and Prevention. Ventilator-associated event (VAE) has been well categorized in adult population; however, in pediatric cohort, while surveillance enhances the detection of infectious and noninfectious complications which can influence patient outcomes, there are many gaps in its classification and management. Establishing a diagnosis of VAP/VAE is crucial in management of a critically ill patient. The role of clinical criteria in concordance with laboratory evidence of inflammatory markers along with chest X-ray helps in supplementing the diagnosis. The presence of culture positivity aids in diagnosis with minimally invasive bronchoalveolar lavage providing a reasonable and safe method. Early empiric antibiotic treatment in suspected patients is beneficial. The role of antibiotic stewardship will help in prevention of antimicrobial resistance in treatment of VAP. More emphasis on VAP prevention measures with multidisciplinary approach is the way forward in overcoming this morbid condition in the intensive care units.

Phthirus pubis infestation is a highly infectious parasitic disease, affecting 1.3–4.6% of people globally. However, the coinfestation of P. pubis on the eyelashes and scalp hairs in children is uncommon, and the clinical characteristics and prognosis have not been fully studied. In this retrospective study, we report five pediatric patients diagnosed with eyelash and scalp coinfestation of P. pubis. The samples were obtained after treatment and sent for pathological examination. The demographic and clinical characteristics of the study participants were analyzed in detail. Numerous lice and nits were detectable on the eyelashes and scalp hairs in all enrolled patients. The ages ranged from 2 to 5 years. The duration of onset ranged from 3 to 10 days. The common clinical presentations were itching (100%) and conjunctivitis (60%). Treatment included eyelash and scalp hair trimming to the root (100%) and mechanical removal of the parasites (100%), in addition to topical tobramycin eye ointment (100%) and phenothrin shampoo (80%). Symptoms resolved by a 1-week follow-up. Pediatric P. pubis coinfestation mainly occurs on the eyelashes and temporal scalp in females, and sometimes contact tracing fails to identify the source. Phthirus pubis infestation of eyelashes can be misdiagnosed as blepharoconjunctivitis. Sexually transmitted diseases should be ruled out for patients with P. pubis infestation. Untreated or persistent cases may lead to several serious infections.

Hydatid bone disease is a zoonotic parasitic infection that is caused primarily by the tapeworm Echinococcus granulosus, and it continues to be a major public health concern in pastoral regions. The reconstruction of limb function after limb salvage surgery remains a challenge for clinicians. The purpose of this study was to determine the clinical efficacy of palliative treatment of the management of advanced pelvic hydatid bone disease. From March 2005 to December 2018, medical records and images of patients with advanced pelvic hydatid bone disease treated with surgery combined with antiparasitic chemotherapy were evaluated retrospectively. The Enneking classification was applied to determine the location of the lesion, and the Musculoskeletal Tumor Society score system was used for outcome evaluation. Fifteen patients who met the criteria were included in this study, with a mean follow-up of 4.40 ± 1.76 years. All patients received treatment with surgery combined with antiparasitic chemotherapy. The mean number of surgical interventions per patient for pelvic cystic echinococcosis was 5.3 (range, 2–9 interventions per patient). Recurrence of pelvic hydatid bone disease occurred in 5 patients and was managed successfully through repeated debridement procedures. Palliative treatment with limb salvage surgery was an effective and practical approach to the management of advanced pelvic hydatid bone disease. Standard antiparasitic chemotherapy, which included albendazole at a dose of 10 mg/kg/day administered in two daily doses for 3 to 6 months, was also considered an essential part of the overall treatment strategy.

Published: July 2023

Virus-induced severe fever with thrombocytopenia syndrome (SFTS) induces a cell-mediated immune response that likely contributes to virus control in SFTS patients. To identify the temporal changes of the cell-mediated immune response, we investigated the changes in serum levels of perforin and granzymes at early periods after illness onset in SFTS patients. We analyzed 32 SFTS patients and compared the temporal patterns of serum perforin and granzyme A and B to that of 20 healthy control adults using the Mann-Whitney U test. Compared with healthy controls, the mean level of perforin was significantly reduced by 81% (P < 0.01) during the first week after illness onset, whereas granzyme B significantly increased by 4.6-fold (P = 0.02) in the first week after illness onset and decreased to normal afterward. During the study period, there was no significant difference in serum perforin and granzyme. These findings indicate that perforin and granzyme B in serum can be considered possible serologic markers that reflect the clinical stage of SFTS. Additional study is warranted for tracking circulating perforin and granzyme in different ages and for an extended period after illness onset.

Museum dr.AK.Gani memerlukan media promosi untuk menarik masyarakat berkunjung ke museum fisik yang menyimpan koleksi bersejarah peninggalan sang pahlawan nasional. Pada pameran bersama museum di Sumatera Selatan, museum dr.AK.Gani turut berpartisipasi dengan memamerkan sejumlah koleksi namun tidak cukup informatif dikarenakan terbatasnya ruang pamer dan petugas yang dapat mempromosikan keberadaan museum. Kegiatan pengabdian kepada masyarakat ini bertujuan merancang brosur inovatif yang memiliki luaran berupa media promosi dalam bentuk brosur yang dapat disebarluaskan kepada pengunjung pameran secara cepat. Brosur dirancang berbasis teknologi Google Map yang memudahkan pengunjung menuju lokasi museum dipandu oleh aplikasi Google Map. Informasi yang dimuat dalam brosur mendeskripsikan museum dan mengilustrasikan koleksi serta bangunan museum dr.AK.Gani sehingga diharapkan dapat menarik minat kunjungan wisata sejarah masyarakat. Hasil evaluasi kegiatan menunjukkan bahwa brosur yang dibuat mempu memberikan informasi yang menarik minat masyarakat berkunjung ke museum dr.AK.Gani. Rata-rata pengunjung setuju bahwa brosur yang dirancang efektif memberikan informasi tentang museum dr.AK.Gani dan meningkatkan minat untuk datang berwisata ke museum fisik. Mitra PkM menyatakan bahwa brosur inovatif sudah sesuai untuk kebutuhan fasilitas layanan informasi museum dr.AK.Gani.

PELATIHAN PEMILIHAN DAN LABEL KEMASAN PADA PRODUK TERASI UDANG REBON KELOMPOK WANITA NELAYAN
Authors: Nurliza Nurliza
Published: July 2023

Udang rebon (Mysis sp.) adalah salah satu hasil perikanan yang sangat diandalkan di Kabupaten Sambas, Kalimantan Barat, terutama pada musim togok, yaitu bulan Februari-Mei. Hasil tangkapan kelompok nelayan dapat mencapai 0,5-1 ton/hari, kecuali musim hujan. Namun, tangkapan menjadi cepat membusuk akibat infrastruktur untuk mengawetkan hasil tangkapan sangat terbatas. Salah satu upaya menaikkan nilai jual dan daya simpannya, maka udang rebon dioleh menjadi terasi oleh kelompok wanita nelayan. Proses pembuatan terasi tersebut masih sangat sederhana karena menggunakan kemasan kertas koran, daun atau plastik biasa sehingga menurunkan mutu produk serta lazim dijual dalam bentuk kering di pasar tradisional di wilayah sekitar. Kondisi ini dimanfaatkan oleh pedagang untuk mengambil nilai tambahnya dengan penggunaan kemasan yang lebih baik. Tujuan kegiatan pengabdian kepada masyarakat adalah pelatihan pada kelompok wanita nelayan agar memiliki pengetahuan dan praktek terkait pemilihan dan label kemasan yang lebih menarik dan aman. Pelaksanaan kegiatan dilakukan pada 18 orang wanita nelayan di Kecamatan Selakau, Kabupaten Sambas dengan analisis deskriptif, dan distribusi frekwensi. Hasil kegiatan menunjukkan bahwa tingkat ketercapaian pengetahuan adalah tinggi dan cukup, tetapi masih ada kesenjangan dengan keterampilannya terutama terkait persyaratan kemasan. Oleh sebab itu, keseriusan dan kemauan untuk memperoleh informasi terkait kebutuhan dan keinginan konsumen, pemasaran dan promosi melalui pameran dan kerjasama stakeholders’ serta dukungan dan peran serta pemerintah daerah melalui pembinaan, penyuluhan, pelatihan, kemudahan akses modal, bantuan alat pengawetan hasil tangkapan serta perbaikan infrastrukur sangat diperlukan untuk mendorong berkembangnya usaha secara berkelanjutan

Developing and Evaluating Sector Rotation Strategy for Indian Equity Markets
Authors: Patel Nikhil
Published: July 2023

This study examines the effectiveness of rotating in and out of a sector based on the stage of a business cycle. Here, we assume that business cycles exist, are part of nature, and neither repeat at a regular intervals nor their intensity or duration are constant. However, we assume that with a perfect set of high-frequency indicators, an investor can perfectly time the business cycle phases. This study divides India's real GDP growth into High, Moderate, Low, and Minuscule growth. GDP Growth is used as an indication of a start/end of a business cycle. In an investor were to create four different portfolios, optimized for each of the business cycle phases, will he/she be able to outperform the SENSEX returns of the buy-and-hold strategy? Here, an attempt to create such four models has been done using Python based on Markowitz Efficient Frontier and Modern Portfolio Theory. Once developed using historical data from September 2005 to March 2020, the study tries to estimate its performance in out-of-sample data, i.e., June 2021-April 2023. Can an investor make higher absolute (not alpha) returns with perfect foresight? We try to evaluate such in this study. Some obvious drawbacks of this model are inapplicability for large investors, mutual funds, etc. However, an investor with small capital and access to data can have an accurate foresight, thus, applying the model in practice can earn higher absolute returns. Even with a tax consideration of moving in and out of sectors, an investor can make a higher absolute return compared to a buy-and-hold strategy.
Giving Voices to Jamaican Canadian Immigrant Women: A Heuristic Inquiry Study
Authors: Dixon Sandra , Amin Dania , Arthur Nancy
Published: July 2023

The Heuristic Inquiry (HI) qualitative method applied in this study explored the role of Pentecostal faith in the post-migration lived experiences of Jamaican Canadian immigrant women (JCIW). Semi-structured interviews were conducted with seven JCIW whose Pentecostal faith helped them to reconstruct their cultural identity post-migration. The creative flexibility of HI allowed for the integration of the primary researcher’s (i.e., first author's) voice into the study alongside those of the co-researchers. Positioning the study within a postmodern social constructionism theoretical framework created space for multiple realities to emerge that were constructed through social interaction and language. These realities were evident in the unique ways in which the JCIW used faith to reconstruct their cultural identity during the migration process. Results revealed four key categories and 10 salient themes which were used to inform theory, research, and practice for counseling professionals. Recommendations for future research in using HI and the topic of cultural identity are discussed.
Dismantling Methodological Silos and Normative Confinements in Qualitative Research: A Shared Meal of Knowledge in a Postqualitative Langar Space
Authors: Singh Kanwarjeet , Southcott Jane , Lyons Damien
Published: July 2023

Building on qualitative approaches, post-qualitative is a turn of “becomings,” never reached but always moving. Turning from and beyond established qualitative traditions, in the post-qualitative, we pursue the leads of St. Pierre and Lather to push qualitative boundaries and offer Langar – a Sikh cultural practice of collective cooking and consumption of a shared meal as an alternative site of knowledge creation. As part, we harness the philosophical virtues of Langar and utilise its resistive prowess to put forward a methodological footprint that turns from the qualitative yardstick of rigor-tested legitimisation of knowledge. We navigate the ontological turns to locate the post-qualitative determinants of Langar and argue for its methodological rightness that disclaim scientism-based warrantability of knowledge building and acceptance.
