Published: August 2021

OBJECTIVE

Postoperative hydrocephalus occurs in one-third of children after posterior fossa tumor resection. Although models to predict the need for CSF diversion after resection exist for preoperative variables, it is unknown which postoperative variables predict the need for CSF diversion. In this study, the authors sought to determine the clinical and radiographic predictors for CSF diversion in children following posterior fossa tumor resection.

METHODS

This was a retrospective cohort study involving patients ≤ 18 years of age who underwent resection of a primary posterior fossa tumor between 2000 and 2018. The primary outcome was the need for CSF diversion 6 months after surgery. Candidate predictors for CSF diversion including age, race, sex, frontal occipital horn ratio (FOHR), tumor type, tumor volume and location, transependymal edema, papilledema, presence of postoperative intraventricular blood, and residual tumor were evaluated using a best subset selection method with logistic regression.

RESULTS

Of the 63 included patients, 26 (41.3%) had CSF diversion at 6 months. Patients who required CSF diversion had a higher median FOHR (0.5 vs 0.4) and a higher percentage of postoperative intraventricular blood (30.8% vs 2.7%) compared with those who did not. A 0.1-unit increase in FOHR or intraventricular blood was associated with increased odds of CSF diversion (OR 2.9 [95% CI 1.3–7.8], p = 0.02 and OR 20.2 [95% CI 2.9–423.1], p = 0.01, respectively) with an overfitting-corrected concordance index of 0.68 (95% CI 0.56–0.80).

CONCLUSIONS

The preoperative FOHR and postoperative intraventricular blood were significant predictors of the need for permanent CSF diversion within 6 months after posterior fossa tumor resection in children.

Published: August 2021

OBJECTIVE

Amid national and local budget crises, cutting costs while maintaining quality care is a top priority. Chiari malformation is a relatively common pediatric neurosurgical pathology, and postoperative care varies widely. The postoperative course can be complicated by pain and nausea, which can extend the hospital stay. In this study, the authors aimed to examine whether instituting a standardized postoperative care protocol would decrease overall patient hospital length of stay (LOS) as well as cost to families and the hospital system.

METHODS

A retrospective study of pediatric patients who underwent an intradural Chiari decompression with expansile duraplasty at a single institution from January 2016 to September 2019 was performed. A standardized postoperative care protocol was instituted on May 17, 2018. Pre- and postprotocol groups were primarily analyzed for demographics, LOS, and the estimated financial expense of the hospital stay. Secondary analysis included readmissions, opioid consumption, and follow-up.

RESULTS

The analysis included 132 pediatric patients who underwent an intradural Chiari decompression with expansile duraplasty. The preprotocol group included 97 patients and the postprotocol group included 35 patients. Patient age ranged from 0.5 to 26 years (mean 9.5 years). The mean LOS preprotocol was 55.48 hours (range 25.90–127.77 hours), and the mean postprotocol LOS was 46.39 hours (range 27.58–77.38 hours). The comparison between means showed a statistically significant decrease following protocol initiation (95% CI 1.87–16.31 hours, p = 0.014). In the preprotocol group, 21 of 97 patients (22%) were discharged the first day after surgery compared with 14 of 35 patients (40%) in the postprotocol group (p = 0.045). The estimated cost of one night on the pediatric neurosurgical intermediate ward was approximately $4500, which gives overall cost estimates for 100 theoretical cases of $927,800 for the preprotocol group and $732,900 for the postprotocol group.

CONCLUSIONS

By instituting a Chiari protocol, postoperative LOS was significantly decreased, which resulted in decreased healthcare costs while maintaining high-quality and safe care.
Nonsyndromic craniosynostosis in Vietnam: initial surgical outcomes of subspecialty mentorship
Authors: Can Dang Do Thanh , Lepard Jacob R. , Anh Nguyen Minh , Tuan Pham Anh , Tuan Tran Diep , Son Vo Tan , Grant John H. , Johnston James M.
Published: August 2021

OBJECTIVE

There is a global deficit of pediatric neurosurgical care, and the epidemiology and overall surgical care for craniosynostosis is not well characterized at the global level. This study serves to highlight the details and early surgical results of a neurosurgical educational partnership and subsequent local scale-up in craniosynostosis correction.

METHODS

A prospective case series was performed with inclusion of all patients undergoing correction of craniosynostosis by extensive cranial vault remodeling at Children’s Hospital 2, Ho Chi Minh City, Vietnam, between January 1, 2015, and December 31, 2019.

RESULTS

A total of 76 patients were included in the study. The group was predominantly male, with a male-to-female ratio of 3.3:1. Sagittal synostosis was the most common diagnosis (50%, 38/76), followed by unilateral coronal (11.8%, 9/76), bicoronal (11.8%, 9/76), and metopic (7.9%, 6/76). The most common corrective technique was anterior cranial vault remodeling (30/76, 39.4%) followed by frontoorbital advancement (34.2%, 26/76). The overall mean operative time was 205.8 ± 38.6 minutes, and the estimated blood loss was 176 ± 89.4 mL. Eleven procedures were complicated by intraoperative durotomy (14.5%, 11/76) without any damage of dural venous sinuses or brain tissue. Postoperatively, 4 procedures were complicated by wound infection (5.3%, 4/76), all of which required operative wound debridement. There were no neurological complications or postoperative deaths. One patient required repeat reconstruction due to delayed intracranial hypertension. There was no loss to follow-up. All patients were followed at outpatient clinic, and the mean follow-up period was 32.3 ± 18.8 months postoperatively.

CONCLUSIONS

Surgical care for pediatric craniosynostosis can be taught and sustained in the setting of collegial educational partnerships with early capability for high surgical volume and safe outcomes. In the setting of the significant deficit in worldwide pediatric neurosurgical care, this study provides an example of the feasibility of such relationships in addressing this unmet need.
Categorizing cortical dysplasia lesions for surgical outcome using network functional connectivity
Authors: Bdaiwi Abdullah S. , Greiner Hansel M. , Leach James , Mangano Francesco T. , DiFrancesco Mark W.
Published: August 2021

OBJECTIVE

Focal cortical dysplasia (FCD) is often associated with drug-resistant epilepsy, leading to a recommendation to surgically remove the seizure focus. Predicting outcome for resection of FCD is challenging, requiring a new approach. Lesion-symptom mapping is a powerful and broadly applicable method for linking neurological symptoms or outcomes to damage to particular brain regions. In this work, the authors applied lesion network mapping, an expansion of the traditional approach, to search for the association of lesion network connectivity with surgical outcomes. They hypothesized that connectivity of lesion volumes, preoperatively identified by MRI, would associate with seizure outcomes after surgery in a pediatric cohort with FCD.

METHODS

This retrospective study included 21 patients spanning the ages of 3 months to 17.7 years with FCD lesions who underwent surgery for drug-resistant epilepsy. The mean brain-wide functional connectivity map of each lesion volume was assessed across a database of resting-state functional MRI data from healthy children (spanning approximately 2.9 to 18.9 years old) compiled at the authors’ institution. Lesion connectivity maps were averaged across age and sex groupings from the database and matched to each patient. The authors sought to associate voxel-wise differences in these maps with subject-specific surgical outcome (seizure free vs persistent seizures).

RESULTS

Lesion volumes with persistent seizures after surgery tended to have stronger connectivity to attention and motor networks and weaker connectivity to the default mode network compared with lesion volumes with seizure-free surgical outcome.

CONCLUSIONS

Network connectivity–based lesion-outcome mapping may offer new insight for determining the impact of lesion volumes discerned according to both size and specific location. The results of this pilot study could be validated with a larger set of data, with the ultimate goal of allowing examination of lesions in patients with FCD and predicting their surgical outcomes.
Social-emotional functioning in pediatric hydrocephalus: comparison of the Hydrocephalus Outcome Questionnaire to the Behavior Assessment System for Children
Authors: Wall Vanessa L. , Kestle John R. W. , Fulton John B. , Gale Shawn D.
Published: August 2021

OBJECTIVE

Hydrocephalus can impact all areas of health, including physical, cognitive, and social-emotional functioning. The social-emotional health of children who have had surgery for hydrocephalus is not well characterized. In this study, the authors sought to examine social-emotional functioning using the Behavior Assessment System for Children, Third Edition (BASC-3) and the Hydrocephalus Outcome Questionnaire (HOQ) in 66 children aged 5 to 17 years.

METHODS

Caregivers of pediatric patients with hydrocephalus completed the BASC-3 and the HOQ. BASC-3 internalizing, externalizing, and executive functioning caregiver-reported scores were compared with the BASC-3 normative sample using one-sample t-tests to evaluate overall social-emotional functioning. BASC-3 scores were correlated with the social-emotional domain of the HOQ using Pearson’s r to determine if the HOQ accurately captured the social-emotional functioning of children with hydrocephalus in a neurosurgery setting. BASC-3 and HOQ scores of children with different etiologies of hydrocephalus were compared using the Kruskal-Wallis one-way analysis of variance to determine if differences existed between the following etiologies: intraventricular hemorrhage secondary to prematurity, myelomeningocele, communicating congenital hydrocephalus, aqueductal stenosis, or other.

RESULTS

Children with hydrocephalus of all etiologies had more difficulties with social-emotional functioning compared with normative populations. Children with different hydrocephalus etiologies differed in executive functioning and overall HOQ scores but not in internalizing symptoms, externalizing symptoms, or social-emotional HOQ scores. The social-emotional domain of the HOQ correlated more strongly with the BASC-3 than did the physical and cognitive domains.

CONCLUSIONS

These results have provided evidence that children who have had surgery for hydrocephalus may be at increased risk of social-emotional and behavioral difficulties, but etiology may not be particularly helpful in predicting what kinds or degree of difficulty. The results of this study also support the convergent and divergent validity of the social-emotional domain of the HOQ.
Sudden-onset paraplegia in a 72-year-old male with a spinal dural arteriovenous fistula: illustrative case
Authors: Ogbu Ikenna I. , Tzerakis Nikolaos , Al-Shamary Zaineb
Published: August 2021

BACKGROUND

Spinal dural arteriovenous fistulas (SDAVFs) are rare vascular malformations of the spine but account for up to 80% of all vascular malformations involving the spine. Few case reports of SDAVFs have been reported in the literature, and even fewer have been described with sudden onset of symptoms.

OBSERVATIONS

The authors described the case of a 72-year-old male with sudden-onset bilateral paraplegia and sensory loss with subsequent inability to bear weight and an initial suspicion of cauda equina syndrome, which was eventually diagnosed as an SDAVF using magnetic resonance imaging. During open surgery, it was difficult to identify the feeder vessels. A postoperative scan showed persistence of the fistula, and the patient had to receive redo ligation with good postoperative status.

LESSONS

Sudden-onset paraplegia is not the typical presentation of SDAVF. All doctors need to be aware of the possibility of an acute presentation with SDAVF, especially with the high likelihood of misdiagnosis and resultant worse outcome due to treatment delays. A high index of suspicion is required to ensure early recognition as well as initiation of treatment.
Mechanical thrombectomy and carotid artery stenting for stenosis of the internal carotid artery with free-floating thrombosis: illustrative case
Authors: Tomoyose Ryuta , Tsumoto Tomoyuki , Hara Kenta , Miyazaki Yuichi , Tokunaga So , Yasaka Masahiro , Okada Yasushi
Published: August 2021

BACKGROUND

The authors report a case in which mechanical thrombectomy and carotid artery stenting (CAS) were performed for acute cerebral infarction with free-floating thrombosis (FFT) in left internal carotid artery (ICA) stenosis. Good results were obtained.

OBSERVATIONS

A 63-year-old man developed sudden disturbance of consciousness and right hemiplegia. He was transported to the authors’ hospital by an emergency vehicle. Head magnetic resonance imaging showed acute cerebral infarction in the left middle cerebral artery region, and magnetic resonance angiography showed poor vascular flow beyond the left ICA. Emergency angiography revealed severe stenosis at the origin of the left ICA and a free-floating thrombus attached to the stenosis and extending to the peripheral side. Percutaneous transluminal angioplasty (PTA) was performed on the stenosis with proximal protection, the thrombus was aspirated under reversal flow, and CAS was performed without exacerbation of clinical symptoms.

LESSONS

PTA, thrombus aspiration, and CAS under reversal flow may be effective treatments for FFT caused by ICA stenosis.
Aplastic or twig-like middle cerebral artery harboring unruptured cerebral aneurysms treated by clipping and bypass surgery: illustrative case
Authors: Takarada Ayako , Yanaka Kiyoyuki , Onuma Kuniyuki , Nakamura Kazuhiro , Takahashi Nobuyuki , Ishikawa Eiichi
Published: August 2021

BACKGROUND

Aplastic or twig-like middle cerebral artery (Ap/T-MCA) is a congenital MCA anomaly. It may present with symptoms of both hemorrhage and ischemia, similar to moyamoya disease, and hemodynamic stress may play an essential role in the development of symptoms in both clinical entities. The optimal treatment remains controversial in symptomatic patients with Ap/T-MCA. This report discussed the treatment method for a patient with Ap/T-MCA with unruptured aneurysms who presented with intraventricular hemorrhage (IVH) treated by aneurysm clipping and bypass surgery.

OBSERVATIONS

In a 46-year-old woman with a sudden headache, computed tomography showed left IVH. Magnetic resonance angiography showed a left MCA aneurysm and MCA trunk stenosis. Three-dimensional angiography demonstrated a plexiform arterial network and multiple aneurysms arising from the MCA and in the plexiform network, leading to the diagnosis of Ap/T-MCA harboring unruptured aneurysms. The patient was successfully treated by craniotomy with aneurysm clipping and bypass surgery to prevent further intracranial hemorrhages and/or aneurysm rupture.

LESSONS

Especially in cases such as Ap/T-MCA, in which hemodynamic stress has a significant effect, the optimal treatment method should be based on vascular morphology and the impact of hemodynamic stress.
Cognitive activity of a forensic expert: psychological aspect
Authors: Soldatenko Olena , Yunatskyi Oleksandr
Published: August 2021

The paper addresses the features of the forensic expert’s cognitive activity during the expertise and the process of drawing a conclusion based on the principle of inner certainty. Some factors which prevent forming of such certainty are considered in the present paper. The peculiarity of the cognitive activity of a forensic expert is that his/her conclusion should reflect the inner conviction, ie the confidence of the expert in its reliability. The objective side of the inner conviction can be only a set of factual data established during the expert study, regardless of any external influences and actions.
Appraisal of Seasonal Rainfall Prediction and Utilization: A Case Study of Kano State, Nigeria
Authors: Alapata Ahmed Yusuf , Ismaila Aliyu , Maigeri Mustapha Ibrahim
Published: August 2021

This work evaluates the accuracy of seasonal rainfall prediction by the Nigerian Meteorological Agency by comparing it with the actual amount of rainfall received. It also measures the perception of the farmers regarding such prediction in the case of Kano State using data collected for the years 2009-2015. A total of eighty structured questionnaires were administered to the respondents in selected areas including Mariri, Hotoro, Zaria road and Gwarzo using purposive and snowball sampling techniques. When comparison between the predicted and the observed amount of rainfall received in the study area was made, the outcome showed a high level of variation throughout the years under study. The results further revealed that the majority of the respondents were not aware of convectional rainfall levels or assumed that the modern prediction method is unreliable. The current study recommends massive sensitization of farmers about the modern rainfall prediction methods considering the erratic nature of the weather and the changing climate, particularly in this era of global climate change.

Authors: Parveen Farhat , Nazir Nadia , Zamir Shazia
Published: August 2021

Teacher competency is the key to effective and quality teaching. According to the Oxford English Dictionary, competency denotes the ability, skill, and strength of an individual used to perform a given task. In order to ascertain the efficacy of the learning outcomes of any education system, teacher competency is measured using knowledge, skills, and attitude (KSA) model. The current study used the same model to assess teacher competency of the secondary school teachers of Islamabad. Stratified random sampling technique was used to choose the desired sample comprising 100 male and 100 female secondary school teachers teaching in Islamabad. Data were collected through personal visits of the selected schools. A self-developed questionnaire consisting of 20 items was used to collect the data. Data were analyzed using various statistical techniques such as ANOVA and the mean, standard deviation, and Pearson correlation coefficient were also calculated. The findings revealed that there is a strong and positive association among all the determinants of teacher competency, that is, knowledge, skills and attitude. The study also found that female teachers have better teaching competency as compared to male teachers. Moreover, private school teachers showed better teaching competency than public school teachers. The study also revealed that teachers with less than 5 years of experience performed better than their seniors.

Authors: Hidayat Dian Indriani , Raharjo Sofyan Budi
Published: August 2021

Beragam manifestasi klinis, patogenesis yang masih belum pasti, dan belum ditemukannya obat yang efektif untuk penanganan Coronavirus Disease (COVID-19) mendorong penggunaan berbagai obat off-label sebagai upaya penyembuhan pasien. Obat anti peradangan dan imunomodulator banyak dipakai dalam terapi terutama untuk kasus berat dan kritis. Kolkisin yang dikenal sebagai obat gout diuji coba sebagai alternatif pengobatan COVID-19. Namun penggunaan obat ini sebagai pilihan terapi pada COVID-19 masih jarang. Tinjauan ini bertujuan untuk mengetahui dampak penggunaan kolkisin sebagai terapi adjuvan COVID-19. Tinjauan literatur ini dilakukan dengan mencari jurnal yang telah dipublikasi secara bebas di berbagai jurnal kedokteran internasional dengan kata kunci “colchicine AND COVID-19 journal” dan diperoleh sebanyak 10 jurnal yang secara spesifik membahas mengenai kolkisin dan COVID19. Penelitian yang ada menunjukkan bahwa Kolkisin memiliki dampak positif terhadap pengobatan COVID-19. Kolkisin memiliki efek anti inflamasi multipel yang tidak spesifik pada target tunggal tertentu dan tidak bersifat imunosupresif. Sifat immunomodulator, anti inflamasi dan antiviral menjadi dasar penggunaan kolkisin sebagai terapi adjuvan COVID19. Kolkisin terbukti dapat mempercepat waktu perbaikan klinis pasien, menurunkan angka kematian, kebutuhan rawat inap, dan lama rawat pasien COVID-19. Sedangkan efek antitrombosis kolkisin pada COVID-19 masih memerlukan penelitian lebih lanjut. Kolkisin perlu diberikan secara berhati-hati terkait efeknya pada gastrointestinal dan perlunya penyesuaian pada gangguan ginjal. Penggunaan kolkisin pada pasien COVID-19 menjadi alternatif terapi potensial karena relatif aman, murah, tersedia banyak, dan penggunaan secara peroral. Dengan hasil tersebut diatas, kolkisin dapat dipertimbangkan sebagai bagian dari usaha penyembuhan pasien COVID-19.

Volt egyszer egy praxisorientált képzési programterv a Rendőrtiszti Főiskolán (1994–1995)
Authors: Dános Valér
Published: August 2021

E cikk szerzője 1994 és 1996 között volt a Rendőrtiszti Főiskola vezetője. Korábban maga is hallgatója volt az intézménynek, „vörös diplomával” végzett. Majd hét esztendőn keresztül oktatója, tudományos kutatója volt az intézménynek, és részese lehetett a komplex  oktatási rendszer elnevezést viselő képzési program kidolgozásának, művelésének. Közvetlenül a rendszerváltoztatást követően a  Belügyminisztérium oktatási szakterület vezetőjeként feladata volt a rendvédelmi oktatás-képzés megreformálása, az oktatással  foglalkozó szervezetrendszer felügyelete. E három területen szerzett széles körű ismerete és tapasztalata predesztinálta arra, hogy a  Főiskola élére történt kinevezését követően „fenekestől felfordítsa” az addigi képzési rendszert, és az általa spekulatív tantervi  elméleten alapuló képzésnek nevezett rendszer helyett egy teljes paradigmaváltást jelentő, praxisorientált képzési rendszert valósítson  meg. Lelkesedése két esztendőn keresztül töretlenül vitte előre elképzelésének megvalósításában. Szakmai  meggyőződéssel és hittel vallotta, hogy az addigi, szocialista típusú ismeretalapú megközelítés helyett a gyakorlatorientált (nevén  nevezve praxisorientált) képzés bevezetésére van szükség. Az elképzelés kidolgozását, képzési programba való foglalását az akkori  belügyminiszter – jelentős elismerés mellett – jóváhagyta. A néhány hónap múlva kinevezett új belügyminiszter a főiskolai parancsnok  kinevezését megerősítette, és javaslata tantervbe foglalását elrendelte.

Mindi (Melia azedarach) is a fast-growing woody plant with potential forcommunity forest development. Mindi wood is used to furniture material, parquet, fancy plywood, and fancy laminated veneer, and it is also exported. Although the communityforest in Deli Serdang Regency is established as a seed source for mindi in North Sumatra,information on its diversity is still lacking. The aim of this research was to get informationabout morphological differentiation of mindi in Deli Serdang Regency. Direct observationand measurement on morphological and growth character of mindi had been conducted inthree populations of community forest in Deli Serdang Regency. Those were Percut SeiTuan population, Biru-Biru population, and Pancur Batu population. The result showed thatof 19 observed morphological characters, there were two characters: number of leave andfruit weight able to differentiate the populations—individual tree from three populationclustering into three groups. The first cluster consists of 35 individual trees from Percut SeiTuan (7 trees), Biru-Biru (12 trees), and Pancur Batu (16 trees). The second cluster consistof 24 trees originated from Percut Sei Tuan (13 trees), Biru-Biru (8 trees), and Pancur Batu(3 trees). A third cluster consists of one tree from Pancur Batu.

Runoff remapping for ocean model forcing
Authors: Martin Torge
Published: August 2021

A Pyhton-based toolbox to remap daily runoff fields of the JRA55-do reanalysis (Tsujino et al., 2018, https://doi.org/10.1016/j.ocemod.2018.07.002) onto any ocean model grid. Runoff from the original global JRA grid is collected and redistributed to a given model coastline. A particular feature is the optional treatment of river mouths: runoff from grid nodes, which is of exceptionally large magnitude after the basic remapping, can be radially spread to ocean nodes farther offshore. The scripts were tested successfully for NEMO ocean model configurations of various resolution (global grids ORCA025 and ORC05 as well as regional nests VIKING10, ORION10, VIKING20X and INALT20X) at GEOMAR, Kiel (see Biastoch et al., 2021, https://doi.org/10.5194/os-2021-37 for an application). General instructions are provided for how to process the original JRA runoff files and also for the optional river mouth treatment. The technique is illustrated by examples of the fragmented coast of Greenland and the Amazon river mouth. While the code is versatile, examples are given for an application with the NEMO ocean model.

A factor analysis of the State debt and the State-guaranteed debt is carried out on the main grounds – the average US dollar exchange rate per year, GDP, revenues and expenditures of the State budget – in order to identify trends in changes in its structure and volumes for the period 2016-2020. The main financial risks and the degree of their impact on debt security are defined, a forecast of the State debt and the State-guaranteed debt of Ukraine for the medium term for 2021-2023 has been developed using the polynomial trend. The likelihood of a worsening the debt situation in Ukraine by 2023 and, as a result, a deterioration in the resilience of public finances due to the unfolding of the coronavirus pandemic, which can be equated with the crises of 2008-2009 and 2014-2015, is proved. Proposals to improve Ukraine's debt security in the context of the coronavirus pandemic have been substantiated. Prospect for further research in this direction is to prove the need to make managerial decisions to ensure the sustainability of public finances, taking into account not only macroeconomic, but also political and institutional factors, the impact of which increases significantly in the context of democracy.

Creating a competitive medical industry in Ukraine, which is based on economic, market principles of modern management and marketing, which will meet the socio-economic and political changes that have occurred recently in Ukraine and continue to this day is the main goal of modern medicine. It is necessary to create such a system of medical care, the functioning of which in Ukraine, on the one hand, will improve the quality of health care standards, and on the other – will improve the state of the health care system and health workers. The biggest problems in the direction of research are: panic-buying increases sales of cough, cold and allergy (hay fever) remedies despite competition from natural treatment initiative; self-medication will continue, as visiting a doctor is considered a last resort; fragmentation continues with local companies leading through lower prices. The aim of the article is to study the trends of cough, cold and allergy remedies in Ukraine and identify the impact of COVID-19 on such segment development. The article examines the medical field and the impact of COVID-19 on its development. Particular attention is paid to the development of such segments as cough, cold and allergy remedies in Ukraine. It was determined that consumers continued the tradition of self-medication during COVID-19, but the pandemic intensified the growth of panic. Retail prices for coughs, colds and allergy remedies are rising. It has been determined that sales of cough, cold and allergy remedies will increase by 8% of the current CAGR value.

Authors:   Research Centre of Industrial Problems of Development of NAS of Ukraine, Semyhulina I. B.
Published: August 2021

The stages of development of the world economy and the peculiarities of the functioning of countries in the world, which are inherent in different time periods, are: changes in trends, emergence and increase of socio-economic and socio-political contradictions, importance of certain key factors for the formation of a policy of managing territorial development under different conditions, all this has led to the emergence of a number of spatial development theories. The authors of theories and models of spatial development considered the development of territories from the point of view of a wide range of factors of influence: geographical, administrative, economic, social, political, innovative, etc., characteristic of different time periods. An effective management of territorial development in modern conditions is becoming relevant in terms of the need not only to solve existing problems, but also to expand opportunities for self-development of territories. The implementation of theoretical provisions of spatial development theories has found a practical reflection in different historical periods of the economy of different countries. Theories of spatial development form the basis of the methodology of public administration, which determines the principles, directions of formation and ways to ensure the functioning of organizational structures and relevant mechanisms, models of development and management, approaches to the use of resources, etc. With the help of spatial theories one explains and anticipates trends, develops models and mechanisms of territorial development, forms instruments for their practical implementation. Due to the importance, complexity and interdependence with a whole range of socio-political, socio-economic, ecological and other processes, the issues of theoretical approaches to the formation and functioning of the optimal model of spatial development constantly remain in the field of view of researchers and practitioners of the world, which further determines the prospects and relevance of studying the defined topic.

Transcending Self-Consciousness: Imagination, Unity and Self-Dissolution in the English Romantic and Sufis Epistemology
Authors: Soltan Beyad Maryam , Vafa Mahsa
Published: August 2021

English Romantic literature of the late eighteenth and early nineteenth centuries often recounts an individual life journey which depicts physical and spiritual pilgrimage and traverses both the inner and outer world to liberate the self and reach a revelatory moment of unification where the division between human mind and the external world is reconciled. For the Romantic poets this reconciliatory state cannot be achieved through rational investigation but via the power of imagination. In this regard, there is striking resemblance between the mystical and philosophical thought of Sufism and the idealistic thought of the English Romantic poets as they both strive for a sense of unification with the Divine or the Ultimate reality, and they both rely on imagination and intuitive perception to apprehend reality. Applying an analytical-comparative approach with specific reference to Northrop Frye’s anagogic theory (1957) which emphasizes literary commonalities regardless of direct influence or cultural or theological distinctions, this study endeavors to depict that certain Romantic poets’ longing for the reconciliation of subject and object dualism via imagination and its sublime product, poetic language, echoes the mystic’s pursuit of transcendental states of consciousness and unification with the divinely infinite. Through analysis of the concept of self-dissolution (fana) in Islamic mysticism and Sufi literature, particularly the poems of Jalal ad-Din Mohammad Balkhi (1207-1273) known in the West as Rumi, the outcome of this study reveals that the Romantics’ yearning for a state of reconciliation, which is prevalent in the major works of the Romantic poets such as William Blake (1757-1827), William Wordsworth (1770-1850), Samuel Taylor Coleridge (1772-1834), Percy Bysshe Shelley (1792-1822), and John Keats (1795-1821), corresponds to the mystic’s pursuit of unity or the Sufi’s concept of self-annihilation or fana.
Mapping Out the Future: A Proposal of A CLIL Research Agenda in China
Authors: Hu Hengzhi
Published: August 2021

This paper sets out to place the research on Content and Language Integrated Learning (CLIL) within the border of Chinese academia. In considering the limited amount of empirical research in China, the author problematises the construction of a shared CLIL research agenda aimed at extending the scope of the current academic scenario. A conceptual model is formulated based on the constructive proposal brought forward by Coyle et al. (2010) that CLIL research should involve the examination and understanding of performance evidence, affective evidence, process evidence and materials and task evidence. Given that almost all the reviewed CLIL studies were conducted in the scope of English language education in higher education, this model is positioned within a broad multilingual and educationally diverse context in China. A more comprehensive, rich and evidence-based research scenario is expected from Chinese researchers whose work is not only to extend the CLIL research agenda but also to probe into it in the long way ahead.
Switching to Online and its Impact on Feedback Processes: A Case Study of Seven L2 English Writing Teachers
Authors: Abdul Ghaffar May , Khairallah Megan
Published: August 2021

This case study explored how the sudden switch from face-to-face to online teaching/learning has impacted the corrective feedback strategies of 7 middle and high school L2 English language writing teachers in a private school in Lebanon. The aim of the study was to investigate how these teachers adapted or altered their feedback processes in the assessment of writing. Teachers’ assessment identities are dynamic constructs composed of assessment knowledge and skills, which are impacted by social, personal, and contextual experiences. Through a feedback assessment survey, an online feedback assessment survey and an open-ended interview, the teachers critically reflected on their former corrective feedback practices as a way to unpack their current online approaches to writing assessment. This study explored the shift to online teaching, the impact on corrective feedback processes and assessment strategies, and professional development needs. Findings indicate that the teachers applied feedback formatively, used feedback to re-teach concepts, and encouraged self-assessment in their practices. However, in most instances, their varied feedback processes declined with the advent of online teaching, and they could not clearly articulate how their assessment practices altered with the adoption of online instruction.  Most stated that they would go back to their original practices as soon as they were back face-to-face in the classroom. Finally, some teachers agreed that professional development would have helped them with the switch to online learning, but they adapted to this environment on their own.
