Authors: martins jose , Zamboni Pedro , Anache Jamil , Weber Nobert , Roque Fábio , Marcato José , Tarso Paulo
Published: September 2022

Using tools to quantify global forest and agricultural area covers and also the food that we produce each year, creates the possibility to develop analysis standards that combine these two different kinds of data temporally and continuously. Intending to bring to light synergies and trade-offs between food production and forest cover area conservation, we created an index called FAVI. The index is a normalization of the area of forests and agriculture, multiplied by the weight of food produced for each country. With important certain restrictions that are explained in the text, this global standard analysis of food production and forest conservation, brings a new form of data analysis for the tables of global food production and forest conservation related discussions forums.

Authors: Liu Jinzhao , Chen Xiangjun , Li Xinjian , Wang Lin , Zhai Di
Published: September 2022

The gangue in gob is a porous material that is generated by breaking the overburden layers. The key governing factor in studying gas flow in gob is the reaction law of void ratios to overburden movement. The evolution of the bearing capacity and void ratios of the gangue during the compression process is investigated in this article. The results show that the compression simulation of Voronoi Tyson and Grain growth blocks can transparently represent the gangue compression process. The contact force between blocks decreases as particle size decreases, while the amount of contact force increases. The strong force chain is illustrated as a "hourglass" and a "hyperbola" in the model. The void ratio of the block gangue combination of particle size decreases in a quadratic function /negatively correlated with the increase of compression. This study is of great significance to the judgment of gas enrichment area.

Authors: Gatehi George Thuo , Nasieku Tabitha
Published: September 2022

The incongruence between corporate governance and financial performance has resulted in the collapse, liquidation, and diminished profitability of several corporations in Kenya. Instructively, companies have been delisted from the Kenyan bourse as a result of irregularities and failures that curtail their profitability. Specifically, audits have pointed to failures in corporate governance, which highlight the lethargy of directors in addressing agency theory conflicts. In this regard, there is a need for evaluating the impact of board characteristics on corporations listed at the Nairobi Securities Exchange (NSE). Board characteristics such as size, independence, and diversity have a significant influence on a firm’s strategic direction. Globally, numerous studies have investigated the relationship between corporate governance and financial performance. However, there is limited scholarly research to ascertain the role of individual board characteristics on listed firms’ financial performance. Thus, this study’s main objective was to determine the effect of board characteristics on the financial performance of non-financial firms listed at the NSE. A quantitative research was conducted using 26 randomly selected non-financial firms listed on the NSE. Using historical financial data from companies’ financial statements, a correlational and regression analysis was conducted using Return on Equity (ROE) as the dependent variable. Notably, diagnostic tests such as the test for multicollinearity, autocorrelation, normality tests were conducted before the Pearson’s correlation test. Importantly, the Panel Data Model was use to determine the goodness of fit, while the Panel Least Square model was used to select the appropriate model for regression analysis. The Fixed Effect Model was the most suitable model. As a result, the findings showed that board size and independence had statistically insignificant effects on the dependent variable, while board diversity (gender diversity) had a statistically significant influence on the financial performance of non-financial firms listed on the NSE.
Topological characterization of Lieb-Schultz-Mattis constraints and applications to symmetry-enriched quantum criticality
Authors: Ye Weicheng , Guo Meng , He Yin-Chen , Wang Chong , Zou Liujun
Published: September 2022

Lieb-Schultz-Mattis (LSM) theorems provide powerful constraints on
the problem, i.e. whether a quantum phase or phase transition can emerge
in a many-body system. We derive the topological partition functions
that characterize the LSM constraints in spin systems with
G_s\times G_{int}Gs×Gint
symmetry, where G_sGs
is an arbitrary space group in one or two spatial dimensions, and
G_{int}Gint
is any internal symmetry whose projective representations are classified
by \mathbb{Z}_2^kℤ2k
with kk
an integer. We then apply these results to study the emergibility of a
class of exotic quantum critical states, including the well-known
deconfined quantum critical point (DQCP), U(1)U(1)
Dirac spin liquid (DSL), and the recently proposed non-Lagrangian
Stiefel liquid. These states can emerge as a consequence of the
competition between a magnetic state and a non-magnetic state. We
identify all possible realizations of these states on systems with
SO(3)\times \mathbb{Z}_2^TSO(3)×ℤ2T
internal symmetry and either p6mp6m
or p4mp4m
lattice symmetry. Many interesting examples are discovered, including a
DQCP adjacent to a ferromagnet, stable DSLs on square and honeycomb
lattices, and a class of quantum critical spin-quadrupolar liquids of
which the most relevant spinful fluctuations carry
spin-22.
In particular, there is a realization of spin-quadrupolar DSL that is
beyond the usual parton construction. We further use our formalism to
analyze the stability of these states under symmetry-breaking
perturbations, such as spin-orbit coupling. As a concrete example, we
find that a DSL can be stable in a recently proposed candidate material,
NaYbO_22.

Authors: Chesnokova N. B. , Kost O. A. , Beznos O. V. , Grigoryev A. V. , Binevski P. V. , Pavlenko T. A.
Published: September 2022

Purpose: to evaluate the topical use effect of angiotensin-converting enzyme (ACE) inhibitor (iACE) Enalaprilat in eye drops on eye blood flow volume, hypoxia degree, ACE activity, and total antioxidant activity (TAA) in aqueous humor of rabbits with experimental ocular ischemia.

Material and methods. Transient ocular ischemia in 30 Chinchilla rabbits was induced by subconjunctivally injecting 0.2 ml of 1 % Phenylephrine. Ocular ischemia degree was assessed by the minute volume of blood flow (MBF), determined with the help of ophthalmic plethysmography. 0.125 % Enalaprilat was administered by instillations. A CE activity in aqueous humor was measured using a spectrofluorometric assay with 0.1 mM Z-Phe-His-Leu substrate; the degree of hypoxia was estimated by the level of lactate in aqueous humor, which was determined by the enzymatic amperometric method. TAA was determined by registering chemiluminescence kinetics in the hemoglobin-H2O2-luminol model system.

Results. A single instillation of iACE in the intact rabbit eye caused a decline of MBF value and A CE activity in aqueous humor. In ocular ischemia, ACE activity and t he lactate level in aqueous humor are increasing, while TAA is decreasing. Enalaprilat instillation in the eyes with ischemia lead to the normalization of MBF, ACE activity, lactate level and TAA in aqueous humor.

Conclusion. Topical iACE in eye drops can penetrate eye tissues. Instillations of iACE during ischemia cause a remarkable increase of eye blood flow and reduce ACE activity, which is increased in ischemia. The anti-ischemic effect of iACE is accompanied by antihypoxant and antioxidant effects. Thus, iACE in eye drops can be used in ophthalmology as an anti-ischemic agent.

Published: September 2022

Purpose:to describe surgical treatment of glaucoma of a patient with Sturge — Weber — Krabbe syndrome. We present a clinical case of a patient with Sturge — Weber — Krabbe syndrome who sought assistance with us due to secondary stage III glaucoma with moderately elevated intraocular pressure. The examination revealed a cutaneous hemangioma of the frontal, and zygomatic area of the left half of the face, the upper and the lower eyelids, and conjunctival and episcleral hemangioma of the left eye. Since local hypotensive drug therapy produced no effect, the patient was offered a surgical treatment: sinus trabeculectomy. A pronounced hemorrhage from the conjunctival vessels, the episclera and choroidal vessels that occurred during the operation increased its duration, but severe complications could be avoided. A hyphema that appeared during the operation was almost completely washed out and dissolved within 5 days. Since scarring processes of the filtration zone were activated in the postoperative period, we resorted to an active tactics of the patient’s management, namely the needling of the filtration zone with the use of antimetabolites and corticosteroids.

Conclusion. Sinus trabeculectomy is an effective method of IOP normalization in glaucoma patients with Sturge — Weber — Krabbe syndrome. Active management of the patient in the postoperative period of the case described allowed us to avoid severe intra- and postoperative complications and to achieve stable clinical and functional results.

Authors: Juldasheva N. M. , Tadzhieva F. S.
Published: September 2022

Diabetic retinopathy (DR) is one of the severe complications of diabetes mellitus (DM). Despite the multiyear research of DR pathogenesis, the role of the vitreous body in DR development has not been sufficiently studied. Purpose: to demonstrate the potentials of multispiral computer tomography for assessing the density of the vitreous body in patients with type I diabetes.

Material and methods. 97 practically healthy individuals (the control group) and 137 patients with type I diabetes (the main group), aged 10 to 35, were tested by multispiral computer tomography to assess their vitreous density.

Results. DM type I patients showed a higher vitreous body density in the central and preretinal areas than healthy individuals. The two observation groups showed a statistically significant difference in the level of glycemia only, whilst no reliable difference in lipid metabolism was revealed.

Conclusion. Multispiral computer tomography is a sufficiently sensitive testing method which allows registering even minor differences in the density of the main components of the vitreous body between healthy people and patients with type I diabetes. The higher density of the vitreous body in type I DM patients is probably associated with a higher level of glycosylation.

Purpose: to investigate the changes of electrophysiological activity of healthy rabbit retina occurring in courses of fractal stimulation (FS) of varied duration in order to obtain new scientific data on how fractal visual signals of low intensity, self-similar with respect to time, affect the retina.

Material and methods. 12 healthy Chinchilla rabbits (24 eyes), were examined before and after FS courses that lasted 1, 4 or 12 weeks, using electroretinographic (ERG), morphometric (optical coherence tomography) and biochemical methods (detection of dopamine in the tear). For FS of rabbits, a device with an LED emitter was developed, which generates nonlinear brightness fluctuation based on the Weierstrass — Mandelbrot fractal functions. The choice of fractal signal parameters used in the work was substantiated. Pattern ERG and ganzfeld ERG were registered according to ISCEV standards; also, photopic flicker ERG was recorded at 8.3, 10, 12, and 24 Hz.

Results. No negative effects of a 12-month FS course on the activity and morphology of the retina, or on dopaminergic processes in the eye of a healthy animal were found, which confirms the safety of using low-intensity FS in the clinic. A statistically significant increase in the amplitude of low-frequency flicker ERGs, a shortening of peak latency, and an increase in the amplitude of the b-wave of the scotopic and photopic ERGs was noted.

Conclusion. To assess possible therapeutic effects of FS, we need to continue the investigation on animal models and human patients with retinal pathology. Considering the changes of retinal activity as revealed in the present paper, we recommend the duration of FS courses from 1 week to 1 month for future studies.
Comparative Study on the National Loss Compensation Act: Focusing on the comparison between Germany and Korea
Authors:   European Constitutional Law Association, Kim Younjin
Published: September 2022

The loss compensation acts in Germany and Korea are similar in basic respects, but different parts are found in specific applications. Germany has applied the ‘expropriation-equal infringement(enteignungsgleicher Eingriff)’ to compensate for the void in legal principles for illegal and irresponsible infringement, and the ‘expropriable infringement(enteignender Eingriff)’ legal principles have been applied to property rights restrictions that appear as an atypical side effect of legitimate administrative action. Germany has elaborately developed the loss compensation act through the victim compensation claim(Aufopferungsanspruch), advanced since the 18th century in the philosophy of natural law, the right to claim the elimination of results, the right to claim damages based on the administrative legal claim-obligation relationships, the right to claim the compensation based on the management of administrative affairs, and the right to claim the reimbursement under public law, in addition.
Unlike Germany, Korea does not recognize ‘expropriation-equal infringement’, ‘expropriable infringement’, and other claims, and unlike Article 14 (3) of the Basic Law for the Federal Republic of Germany, which stipulates ‘expropriation’, Article 23 (3) of the Korean Constitution additionally stipulates the ‘use or restriction of property rights by public purpose. It could not be applied indiscriminately as the legal principles such as expropriation-equal infringements, expropriable infringements, and the victim compensation claim developed in Germany are not perfect theories, however. It is not necessary to accept these claims as the right to claim damages based on the administrative legal claim-obligation relationships and the right to claim the compensation based on the management of administrative affairs could be resolved through the application of civil law regulations, and the right to claim the reimbursement under public law could be settled by the principle of general unfair profits, in addition.
The recent side effects of the COVID-19 vaccine are an opportunity to develop discussions on vaccination damage compensation as the compensation by the State. Germany has resolved the damage compensation for vaccination through the right to claim sacrifice compensation. Korea does not recognize the right to claim sacrifice compensation, but seeks to compensate for vaccination damage through Article 71 of the 「Act on the Prevention and Management of Infectious Diseases(abbreviation: Infectious Disease Prevention Act)」. Since the scope of vaccination damage compensation is narrow, the cause-and-effect relationship should be alleviated in the future, and it is required to prepare specific vaccination damage compensation standards and add compensation methods through pension receipt in the 「Infectious Disease Prevention Act」 and Enforcement Decree of the same Act.
Internet Comments to French Political News: Linguapragmatic Features
Authors: Rolgayzer Anastasiya
Published: September 2022

Digital development creates a complex communicative environment with multiple interaction contexts, e.g., Internet forums. This study focuses on the linguapragmatic features of Internet comments to political news. The research was based on 326 comments to a French news article that described the sanctions against Russia. The research objective was to determine their linguapragmatic characteristics, identify the attitude of mass native speakers to global events, and monitor public political consciousness. The comments proved to contain both explicit and implicit linguapragmatic potential. However, the explicit information was larger in volume. The interpretation analysis made it possible to identify the hidden intentions and subjective attitude of the commenter to the topic under comment.
Beauty- and Fashion-Blogs: Lost in Translation
Authors: Rabkina Nadezhda , Bahtina Lina
Published: September 2022

Fashion and beauty blogs appeared as a result of the globalization of the fashion and beauty industry, as well as the virtualization of popular fashion magazines. They introduce a new type of discourse that attracts both marketers and translation theorists, because the Russian Internet badly needs prompt and high-quality translation of huge volumes of such content. Typical problems of audiovisual translation (compression, synchronization) are superimposed on the abundance of constantly growing terms. Beauty/fashion blogs are a kind of visual-verbal unity, where the visual demonstration of a product is accompanied by a verbal component, i.e., description, instructions, etc. This article introduces an analysis of Vogue video blogs, which confirmed other scientific publications on this topic: language economy and technical specifics of audiovisual translation make loan translation, transcription, and transliteration the most popular translation methods in this type of discourse. The translator must have a certain erudition in fashion and beauty industry, since specialized glossaries on these topics do not have time to record new terms and professionalisms that constantly emerge within this rapidly developing area.
AMPA/Kainate Receptors
Authors: Bigge Christopher F. , Boxer Peter A. , Ortwine Daniel F.
Published: September 2022

AMPA and kainate receptors belong to a common family of ionotropic glutamate receptors. Molecular biology has revealed some of the molecular features that are responsible for selective ion permeability of the receptor comp.lex. The diversity of subunits and their combination into hetero-oligomeric recep or complexes have provided evidence that several subtypes of AMPA/kainate receptors exist within the central nervous system. AMPA (2) and kainic acid (4) are agonists that have been used to define receptor pharmacology, including the issue of receptor desensitization and its relationship to excitotoxicity. Selective AMPA antagonists, such as NBQX (9), and mixed AMPA and NMDA glycine site (GlyN) antagonists, such as PNQX (11), have demonstrated significant neuroprotection in several models of cerebral ischemia and neuronal injury, and have provided the basis for extensive research into this mechanism for neuroprotection by the pharmaceutical industry. Physicochemical properties including poor aqueous solubility and high crystallinity of quinoxalinedione-based molecules have hampered their development. Pharmacophore models of the AMPA recognition site have been generated that are useful for identifying molecular features that may circumvent those issues. Alternative templates have been investigated that are hoped to retain intrinsic affinity at the glutamate recognition site of AMPA/kainate receptors comparable or superior to that of 9 and 11. Noncompetitive antagonists of AMPA receptor function may have a therapeutic advantage in that they will not be reversed by a pool of excess glutamate that is associated with neuronal injury or ischemia. Compounds based upon the 2,3- benzodiazepine analog, GYKI 52466 (28) are reported to have significant neuroprotective and anticonvulsant properties. There is evidence that positive modulation of AMPA/kainate receptors may be useful for improving memory formation·and cognitive abilities. Analogs of cyclothiazide (27) and aniracetam (31) have been investigated to delay or reverse cognitive deficits associated with neurodegenerative diseases. The molecules that are discussed herein are a first generation of agents that modulate and have helped to define AMPA/kainate receptor function. It is expected that a second generation of agents will provide clinical utility in a number of neurological disorders, and provide further insight into the functional activity of receptor subtypes.

Authors: Starrett John E. , Dworetzky Steven I. , Gribkoff Valentin K.
Published: September 2022

BK channels are large conductance calcium-activated potassium channels that are found in many tissues, including excitable cells such as myocytes and neurons. The high conductance and dependence on calcium of BK channels suggests that modulation of these channels may have a pronounced effect on tissues in which they are expressed. Within the past four years, a variety of small molecules and natural product-derived modulators of BK channels have been described. This review will focus on compounds which are openers and blockers of BK channels and their therapeutic potential, with introductory sections covering the biophysics, pharmacology and molecular biology of BK channels.

Published: September 2022

The theory of accomplishment-generating motivation only adopts a social cognitive method to research behavior and motivation in sports education settings, illuminating how achievement goal theory is useful for anticipating and explaining beliefs, reactions, and behaviors in achievement settings. This study aimed to investigate how different teaching approaches teacher-centered and student-centered affected the emotional and cognitive motivational responses of students during physical education classes. Using several Mosston and Ashworth teaching methods, including command style, reciprocal style, and guided exploration style, four teachers instructed 92 students. To evaluate teaching style, the Ames coding system was employed. In this inquiry, a strategy of mixed methods was used. By adjusting the work design, authority, recognition, grouping, assessment, and class time structure, the video data was evaluated. The hard disk software enables the recording of audio and video recordings as well as the real-time analysis of information acquired from course observations in physical education. An ANOVA analysis with the Bonferroni correction method was carried out to prevent Type 1 errors, and it produced an alpha level of 0.002 as a result. The command style, reciprocal style, and guided style all performed significantly differently, according to the Tukey test, in terms of total mastery and teaching style effectiveness. According to the findings, guided and reciprocal discovery styles were more effective than command approaches in terms of student mastery, less focused teacher behavior, and cognitive and emotional responses.

To study the structure and properties of materials, the methods of luminescent spectroscopy and X-ray phase analysis were used. It has been shown that the resulting nanocomposites are capable of photogeneration of singlet oxygen under the action of UV and blue light. The synthesized materials consist of nanosized hexagonal ZnO crystals and cubic ZnAl2O4 crystals doped with Cu. The study of luminescent properties showed that nanocomposites can be used as down-converters of light that convert radiation from the UV-C range to UV-A and the visible spectral range.

The features of light absorption and localization in one-dimensional chirped photonic crystals (PCs) are studied. It is shown that although chirping leads to the loss of ideal periodicity, the integral over a wide spectral region light energy density practically does not change. We have shown that violation of the ideal periodic structure (chirping) can not only decrease the integral in the broad spectral region absorption, but also lead to an increase in this absorption in the PC, and this depends on the form of chirping and the form of modulation of the imaginary part of the dielectric permittivity. A study of the evolution of the absorption spectra when the chirping contrast is changed showed that at certain values of the chirping contrast, mini-zones of transmission appear in the photonic band gap, where significant absorption is observed.

Multivariate calibrations of concentrations of C, Mn, Si, Cr, Ni and Cu have been developed by the partial least squares method for 31 to 39 standard samples of low-alloy steels using low-resolution emission spectra (190-440 nm, resolution 0.4 nm, step 0.1 nm). Three methods of spectral variables selection are considered: a method of ranking spectral variables by their correlation coefficient with the value of the calibrated parameter, a successive projection algorithm and an original modification of searching combination moving windows. The partial least squares model with the spectral variables selection by the method of the searching combination moving windows for C is quantitative: the root mean square error is 0.004%, the residual predictive deviation in the test dataset is 23.4 in the concentration range 0.13 to 0.43 %. Calibrations of Mn (0.04% and 5.2 in the range of 0.47–1.15%), Si (0.003% and 20.7 in the range of 0.15–0.33%), Cr (0.04% and 3.1 in the range of 0.09–0.43%) and Ni (0.01% and 4.8 in the range of 0.05–0.25%) are also quantitative. For Cu in the concentration range of 0.06–0.26%, calibration is qualitative (0.04% and 1.4).
Effect of Microwave Radiation on the Development of a Porous Aluminum Carrier of the Active Mass of Catalysts in Heterogeneous Catalytic Reactions
Authors: Muradova Peri
Published: September 2022

In this study, we prepared a fine-grained, aluminum-reinforced alumina support matrix of the active mass of catalysts, which showed activity in heterogeneous catalytic reactions stimulated by electromagnetic radiation in the microwave range. The support absorbed microwave radiation of 2.45 GHz. We compared the textural characteristics of samples of Аl/Аl2О3 supports obtained by conventional heat treatment to those synthesized by heat treatment in a microwave field. We found several advantages of heat treating potential supports of the active mass by using microwave radiation. Using the examples of joint deep oxidation of n-butane and carbon monoxide, dealkylation of toluene with water vapor into benzene, and acidylation of diethyl amine with m-toluic acid, we found that after exposure to microwave radiation, the fine-grained aluminum powder-reinforced Аl/Аl2О3 support can be used for preparing catalysts that can be used in reactions stimulated by a microwave electromagnetic field.

Authors: Jerome Gerald J , Miller Kamilla
Published: September 2022

BACKGROUND

Obesity is a global pandemic. Lifestyle approaches have been shown effective for weight loss and weight loss maintenance. Central to these evidence-based approaches are increased physical activity, decreased caloric intake, and regular self-weighing, along with the tracking of these behaviors.

OBJECTIVE

This descriptive exploratory report examines accessible strategies used to track physical activity, diet, and weight among adults who are legally blind. These health behaviors are essential components to evidence-based weight loss programs.

METHODS

Participants (≥ 18 years) who self-identified as being legally blind were recruited from low vision advocacy groups. They completed a series of telephone administered surveys and an in-person visit for height and weight assessment.

RESULTS

The participants (N=18) had an average age of 31.2(SD=13.4) years, 50% were normal weight (BMI 18.5 to 25), 44% were female, 44% were Black, and 39% were Non-Hispanic White. Most participants (89%) used their smart phone to access the internet daily, and 67% had at least 150 mins/week of exercise. Those tracking health behaviors were using electronic notes, smart phones, and apps. Providing individuals with a talking scale was the most consistent recommendation (66%) to facilitate independence in managing weight through lifestyle changes.

CONCLUSIONS

Greater attention is needed to ensure accessibility of weight loss programs. Further efforts are needed to provide those with low vision accessible support for lifestyle-based weight management.

Published: September 2022

Developments are carried out to enhance the performance of vertical axis wind turbines (VAWT). This paper studies the performance of the ducted wind turbine with convergent duct (DAWT). Basically, the duct technique is utilized to provide the desired wind velocity facing the turbine. Methodology was developed to estimate the decisive performance parameter and to present the effect of the convergent duct with different inlet angles. The ducted wind turbine was analyzed and simulated using MATLAB software and numerically using ANSYS-Fluent 17.2. Result of both approaches were presented and showed good closeness for the two cases of covering angles 12  and 20 respectively. Results also showed that the convergent duct with an inlet angle 12   and 20  improved the coefficient of performance at a specified tip speed ratio by 25.8% and 33.33% respectively in the productivity of wind turbine.
Checking Out Me History, Tings an Times, and White Comedy: Re-shaping and re-playing the post-colonial identity
Authors: Liapopoulou Adamidou Elena
Published: September 2022

The main purpose of this article is to show how John Agard’s Checking Out Me History, Linton Kwesi Johnson’s Tings an Times and Benjamin Zephaniah’s White Comedy play along the “spectrum of the spoken word”, as Agard himself describes it, and how their words are spoken as concurrent signs of resistance against the colonizing past. They introduce a kind of poetry that, with all its political force, quite literally “makes something happen”. In other words, through a shared happening among performer and spectators, these poets stand in front of the post-colonial eyes as the colonized body, with all that it carries, taking advantage of the effective immediacy of the performance while returning back to the origins of poetry, namely its oral tradition. Based on a post-colonial geometry of self-re-definition and historical re-membering, the past is reclaimed as the personas / performers / writers / speakers carve history into the shape of their own body and carve themselves inside and outside of history. When they confront and question themselves, they confront and question their spectators and history itself as a spectator of its happenings: how can human beings walk in and out of history’s play without crossing the lines of complicity and how can the rules of the play be subverted?
“The Graphic Proximity of Intimate Loss”: the Role of Narrative Medicine in Articulating Marginalised and Excluded Voices
Authors: Twinberrow Hannah Louise
Published: September 2022

Academics apply value judgments on the legitimacy of Narrative Medicine and whether it actually evokes an untapped empathy in medical professionals. However, by adopting a purely educational perspective, academics exclude the voices of the sick/dying who exist beyond institutional walls. In Section I, this paper unpacks the opposing views surrounding the successes and limitations of Narrative Medicine but ultimately moves to understand the ways in which it seeks to reach the otherwise excluded voices of the sick/dying. This paper then adopts Eve Kosofsky Sedgwick’s White Glasses (1991) as a case study, in Section II, to further probe the ways in which Narrative Medicine can embrace diversity and interrogate the subjectivity of Narrative. However, whilst an individual narrative such as Kosofsky Sedgwick’s offers insight into a singular lived experience of suffering, Narrative Medicine as a genre excludes many voices when it disregards those with an inability to describe their lives narratologically. So, in Section III, this paper explores the potentiality for a more all-encompassing interpretation of Narrative Medicine which holds space for more diverse representations of suffering. Through the analysis of Frida Kahlo’s What the Water Gave Me (1938) this paper argues that by embracing pictorial representations of human experience, Narrative Medicine can evolve into more inclusive space. The role of Narrative Medicine in the Medical Humanities remains mobile but, despite its limitations, a personalised approach to pathography articulates the marginalised voices of the sick/dying.

Published: September 2022

In this paper we introduce the notion of orbit equivalence for semi-group actions and the concept of generalized linear control system on smooth manifold. We prove that, under certain conditions, the semi-group system of a generalized linear control system on a smooth manifold is orbit equivalent to the semigroup system of a linear control system on a homogeneous space.

Published: September 2022

Abstract: Background: COVID-19 has affected many people around the globe and is known for its effect on the lungs in the human body. However studies have shown the association of COVID-19 and its effect on other organs of the human body. Pheochromocytoma is a neuroendocrine tumor caused by the mutation in the genes and causes overproduction of catecholeamines in the human body resulting in hypertension, headache, elevated sweating, anxiety and panic attacks. Studies have determined that COVID-19 causes adrenal dysfunction but limited data is available to determine the direct relationship of COVID and pheochromocytoma. Case presentation: The current study is based on the report of a 30 year old female patient who was admitted in the hospital for the symptoms of hypertension, dyspnea, and severe headache. The patient was also having panic attacks prior to the admission in the hospital. Conclusion: The patient was diagnosed with pheochromocytoma and COVID-19. The patient showed the symptoms of activated inflammatory immune response in the adrenal gland which resulted in overproduction of catecholeamines caused by COVID and highlights the association of COVID and pheochromocytoma

Authors:   Korean Academy of Leadership, Yan Dong , Li Longzhen , Choi Yeon
Published: September 2022

Thriving at work is a positive psychological state which involves learning and vitality. High level of thriving at work facilitates employee development and organizational performance. In this study, the relationship between self-sacrificial leadership and followers’ thriving at work was tested with followers’ interpersonal justice perception as mediator. Using the data from 476 Chinese employee samples, we found strong supports for all the hypothesized statements, including the mediating mechanism of perceived interpersonal justice and the moderating effects of perceived corporate social responsibility. The findings would contribute to better understanding the relationship between self-sacrificial leadership and employees’ thriving at work, a recently emerging construct of positive psychology. In conclusion, we present theoretical and practical implications for improving leader effectiveness and employee thriving at work, and suggest directions for future research.
