Published: July 2022

Background:

Periodontal and peri-implant disorders are etiologically linked to bacterial biofilms. The researchers wanted to see how well the erbium-doped yttrium aluminum garnet (Er:YAG) laser removed bacterial biofilms along with attached epithelial cells (EC), gingival fibroblasts (GF), in addition to osteoblast-like cells (OC) dentin along with titanium surfaces compared to previous therapy methods.

Methodology:

3.5 days were spent growing bacterial biofilms on standardized dentin and also titanium samplings using a sand-blasted along with the acid-etched surface. Following that, the specimens were positioned into pockets that had been formed artificially. The following approaches were used to remove biofilm: (1) Er:YAG, (2) photodynamic therapy (PDT), and (3) curette (CUR) along with supplementary PDT (CUR/PDT). The remaining biofilms' colony forming units (CFUs) were determined, as well as the attachment of EC, GF, in addition to OC. Analysis of variance with a posthoc least significant difference was utilized in the statistical analysis.

Results:

When compared to untreated dentin and titanium surfaces, all therapy strategies reduced total CFUs in statistically significant biofilms (p = 0.001). On the dentin, Er:YAG was as effective as CUR and PDT, but not as effective as CUR/PDT (p = 0.005). The application of Er:YAG on titanium surfaces leads to statistically significantly improved biofilm eradication equated to the supplementary three therapies (all p = 0.001). On untouched infested dentin and titanium surfaces, the counts of attached EC, GF, and OC were the lowermost. Atop the dentin, increased EC counts were detected after CUR/PDT (p = 0.006). On titanium, all cleaning procedures increased the counts of attached EC by a statistically significant amount (p = 0.001), with no variations between groups. After Er:YAG decontamination, there were statistically substantially elevated amounts of GF (p = 0.024) and OC (p = 0.001) than on untreated surfaces.

Conclusion:

The usage of Er:YAG laser to ablate subgingival biofilms and, specifically, to decontaminate titanium implant surfaces appears to be a promising strategy that needs further research.
EM_GA-RS: Expectation Maximization and GA-based Movie Recommender System
Authors: K N Asha , Rajkumar R
Published: July 2022

This work introduced a novel approach for the movie recommender system using a machine learning approach. This work introduces a clustering-based approach to introduce a recommender system (RS). The conventional clustering approaches suffer from the clustering error issue, which leads to degraded performance. Hence, to overcome this issue, we developed an expectation- maximization-based clustering approach. However, due to imbalanced data, the performance of RS is degraded due to multicollinearity issues. Hence, we Incorporate PCA (Principal Component Analysis) based dimensionality reduction model to improve the performance. Finally, we aim to reduce the error; thus, a Genetic Algorithm (GA) is included to achieve the optimal clusters and assign the suitable recommendation. The experimental study is carried out on publically available movie datasets performance of the proposed approach is measured in terms of MSE (Mean Squared Error) and Root Mean Squared Error (RMSE). The comparative study shows that the proposed approach achieves better performance when compared with a state-of-art movie recommendation system.
Baker domains and non-convergent deformations
Authors: Robles Rodrigo , Sienra Guillermo
Published: July 2022

For an entire transcendental function

f

with a non-completely invariant Baker domain

U

, we study the pinching process of paths in

U

with certain restrictions, that we call Baker laminations. We show that if some curve in the Baker lamination of

f

joins a point in the boundary of

U

with infinity, then the deformation does not converge. Thus, in this particular case, the boundary of the space of deformations of

f

is incomplete.
Invariant Gaussian fields on homogeneous spaces: explicit constructions and mean nodal volume
Authors: Afgoustidis Alexandre
Published: July 2022

We review and study some of the properties of smooth Gaussian random fields defined on a homogeneous space, under the assumption that the probability distribution is invariant under the isometry group of the space. We first give an exposition, building on early results of Yaglom, of the way in which representation theory and the associated special functions make it possible to give completely explicit descriptions of these fields in many cases of interest. We then turn to the expected size of the zero-set: extending two-dimensional results from Optics and Neuroscience, we show that every invariant field comes with a natural unit of volume (defined in terms of the geometrical redundancies in the field) with respect to which the average size of the zero-set is given by a universal constant depending only on the dimension of the source and target spaces, and not on the precise symmetry exhibited by the field.
Rational motivic path spaces and Kim’s relative unipotent section conjecture
Authors: Dan-Cohen Ishai , Schlank Tomer M.
Published: July 2022

We develop the foundations of commutative algebra objects in the category of motives, which we call “motivic dga’s.” Works of White and Cisinski and Déglise provide us with a suitable model structure. This enables us to reconstruct the unipotent fundamental group of a pointed scheme from the associated augmented motivic dga and provides us with a factorization of Kim’s relative unipotent section conjecture into several smaller conjectures with a homotopical flavor.

Despite recent success in reducing the regional incidence of Plasmodium falciparum malaria, cases of zoonotic malaria are on the rise in Southeast Asia. The Cambodian National Malaria Surveillance Program has previously relied on rapid diagnostic tests and blood smear microscopy with confirmatory polymerase chain reaction (PCR) testing in a subset of cases to further distinguish P. falciparum, P. malariae, P. ovale, and P. vivax species. Here, metagenomic next-generation sequencing identified P. knowlesi mono-infection in six Cambodian patients initially diagnosed with P. malariae by blood smear microscopy in February–May 2020. These findings of recent human infections with P. knowlesi in Cambodia led to the incorporation of P. knowlesi–specific PCR diagnostics to national malaria surveillance efforts.

BackgroundAlthough blended learning (BL) is being adopted in public and private higher learning institutions (HLIs) in Rwanda, little is known about students’ use of BL in their learning activities. This article describes a qualitative descriptive study of students’ perceptions and experiences of BL in Rwanda’s post-secondary nursing and midwifery programs in public and private HLIs.MethodsThirty-three nursing and midwifery students from all public and private HLIs in Rwanda exposed to BL were invited to participate in three online focus group discussions (FGDs) conducted using a developed FGD guide with open-ended questions. Inductive content analysis was used to analyze the transcripts.ResultsThree main themes emerged from the data analysis:(1) BL perceived as a new and effective teaching and learning approach, (2) Contextual challenges to the BL method, and (3) Recommendations to improve the BL method. From students’ experiences, the benefits included but were not limited to the flexibility of the approach, time, and cost-saving. However, several challenges were identified, including technological issues such as lack of ICT skills and poor internet connectivity.ConclusionThis study provides insights into the usefulness of BL in HLIs and offers recommendations on how BL teaching and learning can be improved to strengthen nursing and midwifery pre-service education quality.Rwanda J Med Health Sci 2022;5(2):203-215

Spatial and Seasonal Estimation of Tropospheric Radio Refractivity in Nigeria
Authors: Tanko M. M. , Liman M. S. , Lumbi W. L. , Aliyu U. S.
Published: July 2022

The spatial and seasonal variation of tropospheric radio refractivity of Nigeria has been studied using meteorological variables (temperature, relative humidity and pressure) retrieved from the archive of the United States’ National Aeronautics for Space Administration (NASA). This work established a seasonal variation. The results also revealed an increase in radio refractivity from minimum of about 270N-units at Abadam to maximum of about 415N-units at Warri. The variation of radio refractivity is synchronous with rainfall in most of the stations especially those in the Guinea Savannah, Tropical Rainforest and Coastal areas where the effects of august break manifest vividly on the curves. Intense refractivity was measured mostly in the tropical rainforest and coastal areas. This could be attributed to the intensity of rain and the length of the wet season in those locations. The Sahel, Sudan and Guinea savannah which experience less rain with short period of wet season recorded reduced refractivity. Just like rainfall, the movement of Inter Tropical Discontinuity (ITD) is also found to be linked to the variation of the radio refractivity. The northward movement of the ITD brings with it elevated refractivity while the southward movement leads to reduced refractivity. This is because the ITD is an element of two high pressure cells which influences its motion. Majorly, the seasonal variation is found to be the product of climate except in some high ground areas where the topography was found to be majorly responsible.

Published: July 2022

Krisis lahan merupakan hal yang krusial dan menjadi momok bagi kedaulatan negara. Hal tersebut merupakan problem yang telah menggurita secara historis. Untuk menanggulangi hal tersebut, negara sebetulnya telah mengatur agar Reforma Agraria dijalankan melalui UUPA tahun 1960. Lebih jauh dari pengesahan UU tersebut, Islam dengan al-Qur’an dan Hadis telah menetapkan konsep keadilan agraria melalui hukum dan etika yang diajarkan. Tulisan ini bermaksud mengeksplorasi konsep-konsep yang terdapat pada pedoman kaum muslimin tersebut dan bagaimana bentuk kontribusinya dalam mengatasi krisis lahan. Hasil dari penelusuran ini diperoleh beberapa poin kesimpulan mengenai peran Islam dalam upaya mewujudkan keadilan agraria dalam al-Qur’an dan Hadis. Kontribusi tersebut berupa Konsep-ideal dan praksis. Konsep-ideal yang termaktub di dalam al-Qur’an dan hadis antara lain: 1) Bumi dan seisinya adalah milik Allah yang dititipkan kepada manusia untuk dikelola demi berlangsungnya kehidupan, 2) melarang perampasan tanah, 3) menghidupi lahan yang mati 4) berserikat dalam mengelola sumber daya agraria, 5) membagi tanah kepada tunakisma dan 6) menerapkan kebijakan tanah milik publik/hima. Konsep-konsep tersebut adalah pondasi yang mengusung visi dari Islam yang mengutamakan kehidupan ‘adl wa al-ihsan. Sementara bentuk praksis dari kontribusi yang telah diberikan kepada negara, termanifestasikan ke dalam peran ulama yang telah ikut andil dalam merumuskan UUPA tahun 1960.

Predicting English Language Attainments in Higher Education: Self-Efficacy Scales vs. Past Performances
Authors: Rudd Matthew
Published: July 2022

Abstract—This paper aims to empirically test Bandura’s (1977; 1986) claims that the beliefs people hold in their attainment potential predict standards of achievement more accurately than records of past performance, as the latter represent quiescent events unable to account for change. To investigate Bandura’s theoretical ideology, this quantitative research study thoroughly tested the accuracy of self-efficacy scales by comparing the grades 111 third-year university business students believed themselves capable of achieving vis-à-vis subsequent end-of-year English language scores. In relation to past performances, the present study compared students’previous second-year scores with those attained at the end of their current third year. This helped to determine whether students’ future performances can be computed more accurately as a function of their personal efficacy beliefs rather than by assumptions based on past performances. The results of this experiment were mixed. Initial t-test calculations inferred that there was no significant difference between prior stated beliefs of self-efficacy and end-of-third-year English scores (English Y3 = 63%; self-efficacy = 64.23%, p <0.05, not sig). In the same vein, students’ prior second-year scores were significantly different to those achieved in their third year (English Y3 = 63%; past performance Y2 = 56.64%, p <0.05, sig); suggesting that self-efficacy beliefs more reliably project future performances than past exploits. Nevertheless, while self-efficacy scales proved to be accurate in general terms, when measuring on a more task-specific level (such as speaking) or sub-group level (namely student ability), it transpired that such data deriving from self-efficacy scales became increasingly inconsistent. These confounding implications are discussed at length in this paper.

Islam dan Modernitas merupakan dua hal yang berbeda dalam konteksnya. Islam sendiri tertuju kepada sebuah keyakinan pada diri manusia yang bersumber dari wahyu ilahi yang didalamnya mengandung aturan-aturan dalam kehidupan bagi pemeluknya. Sedangkan modernitas adalah sebuah perkembangan yang pasti terjadi dalam kehidupan dan berpengaruh pada aspek kehidupan dalam lingkup yang sangat luas. Dengan munculnya modernitas dalam dunia islam akan memunculkan generasi muslim yang memiliki pemikiran dan pengetahuan modern juga berlandaskan iman dan taqwa. Karena dalam sudut pandang islam, modernitas tidak serta merta dapat diterima begitu saja sebab ada hukum-hukum dalam islam yang tidak padu dengan perkembangan modernitas global yang terjadi.
IF THE PAST TEACHES, WHAT DOES THE FUTURE LEARN? Ancient Urban Regions and the Durable Future

How can we transform urban environments to encourage durability and mediate the social price of myriad risks and vulnerability?Our work here is to build a bridge from archaeology to mainstream architectural and design theory. The study of places, landscapes, and regions links the two fields. Architecture can be shaped and enhanced by the long-term cultural and geographic perspective afforded by archaeology; architecture can offer archaeology a ride into the future. We hope that our efforts are novel enough to be inspiring and connected enough to allow existing concepts to be furthered. The bridge unites three domains: material, social, and aesthetic. We look to the past to find material technologies—new engineering and conceptual solutions to an array of problems—and the past obliges with many examples. However, these technologies in their material aspects are only part of the story. The archaeologist sees them as playing a role in a system. This system, while mechanically functional, is also profoundly social: it includes administrative structures, but also innumerable other kinds of relationships—kin groups, neighborhoods, genders—that mirror the embedded relations between humans and nature. As in architecture, systems include semantics and aesthetics: not only are these forms pleasing to the eye, but they also tell stories of history and place and give identity and meaning to the lives in which they are enmeshed. This multi-functionality and multi-vocality are inherent in past systems.
Study of the Content of Essential Mineral Elements in the Feed of Dairy Cows Against the Background of increased Concentrations of Toxic Metals Cd and Pb in Plants

Published: July 2022

Uncontrolled entry of pollutants – heavy metals into the environment creates obstacles to the production of environmentally safe, biologically complete cow's milk. The accumulation of pollutants in the soil reduces the supply of essential mineral elements to plants, which are necessary to ensure the full feeding of animals. In such environmental situations, it is important to analyse feed rations for the content of essential and non-essential mineral elements. Samples of feed included in the main diet were taken on four experimental farms specialising in the production of cow's milk, the agroecosystems of which were located around the industrial centre and near environmentally unfavourable objects – roads, enterprises for the extraction (processing) of gas condensate, etc. The samples were analysed for the content of mineral elements by atomic adsorption spectrophotometry. Statistical data processing – STATISTICA software suite version 10.0. The feed was found to exceed the permissible level for cadmium by an average of 2.1-3.2 times, lead – 2.4-5.7 times, copper – 1.4-2.3 times, zinc – 1.2-2.4 times. In cereal and legume hay, the concentration of cadmium and lead exceeded permissible levels by 3.2 and 5.7 times, respectively. Against this background, there is a deficiency of calcium in various types of diets of cows from 1.4% to 47.5%, phosphorus – from 1.5% to 62.3%, magnesium – from 2.7% to 64.4%, potassium – from 0.8% to 37.9%, sulphur – from 2.3% to 48.8%, among trace elements, iron – from 2.3% to 48.8%, cobalt – from 5.0% to 80.0%, iodine – from 4.0% to 60.7%. The reason for the deficiency of vital mineral elements in plants (feed) is different, including changes in soil pH, but mainly antagonism between mobile forms of toxic elements and essential elements. For the production of high-quality milk, it is necessary to normalise toxic metals in the diets of cows with different types of feeding and eliminate the lack of minerals with the help of specially developed feed additives (mineral and vitamin premixes), which will prevent elementosis in cows, which is a pressing issue in many countries of the world. Future studies will be aimed at monitoring the concentration of mineral elements in animal feed kept in the forest-steppe and steppe zone and Donetska oblast of Ukraine
Influence of Weather Conditions on the Duration of Interphysical Periods and Yield of Durum Winter Wheat
Authors: Korkhova Margaryta , Mykolaichuk Vira
Published: July 2022

Despite the high genetic potential of productivity of new varieties, the yield of durum winter wheat remains low. One of the reasons for this is non-compliance with the recommended cultivation technologies, which would take into account the genetic characteristics of different varieties, their adaptation to the climatic conditions of the region. Due to insufficient scientific studies of the impact of weather conditions on the productivity of durum winter wheat, taking into account the main strategy of agricultural adaptation to negative climate changes in the southern steppe of Ukraine, the research topic is relevant. The aim of the work was to determine the degree of influence of changes in weather and climatic conditions in the main interphase periods on the growth and development and yield of winter durum wheat grain, depending on the varietal composition. Field studies were conducted during 2014-2020 years in the experimental field of the MNAU training, research and practical center with four varieties of winter durum wheat. In the course of the study, generally accepted methods were used: system approach and systems analysis, monographic, analysis and synthesis, field research and statistical mathematical, etc. Its predecessor was black steam, the sowing period was October 1st. According to the results of research, it was determined that the formation of winter durum wheat grain yield was significantly influenced by the duration of interphase and vegetations and the amount of precipitation. The weather conditions of 2014, 2016 and 2019 were more favorable for the germination of winter durum wheat seeds, when the plants reached the sum of effective temperatures of 70.0-89.1 ° С, the duration of the interphase period "sowing-seedlings" was only 11-12 days. In favorable yields in 2016 and 2019 years the duration of the vegetation of plants was the longest – 296 and 288 days, respectively, with the amount of precipitation for the reporting period – 358.5-402.0 mm, and in unfavorable years in 2018 and 2020 years the vegetation was 272 and 276 days with the amount of precipitation 256.9 and 308.9 mm. The highest average yield of winter durum wheat grain by variety was formed in 2016 year as 7.24 t/ha, which was by 8.3-43.5% higher than in other years studied

Authors: Deshmukh Yogeshwari Anay , Vaid Sanjay , Chandorkar Aparna , Atre Ashish , Patil Sunil
Published: July 2022

In recent times, India has been in the midst of a notifiable epidemic of mucormycosis (a rare angio-invasive fungal infection), within the ongoing global coronavirus disease 2019 (COVID-19) pandemic. Epidemiological studies have reported the estimated prevalence of mucormycosis to be around 70 times higher in India as compared to the global data, even in the pre-COVID era. However, in the last 3 months, our city witnessed an unprecedented surge in cases of post-COVID-19-associated rhino-orbital-cerebral (ROC) mucormycosis.

This pictorial review aims to illustrate the entire imaging spectrum of mucormycosis in the head-neck-face region. Along with the usual sites (nose, paranasal sinuses, orbits), this disease also involves the skull base, palate, temporal bone, and deep neck spaces. Many cases also demonstrated morbid and, at times, fatal intracranial and neurovascular complications.

This review also aims to provide a structured reporting template that will prove useful to the radiologists interpreting imaging studies of ROC mucormycosis.
Arterial stiffness and atherosclerosis in systemic lupus erythematosus patients
Authors: Dziedzic-Oleksy Hanna , Mazurek Adam , Bugała Kamil , Perricone Carlo , Drabik Leszek , Płazak Wojciech
Published: July 2022

Introduction

Systemic lupus erythematosus (SLE) is characterized by early atherothrombosis. Pulse wave velocity (PWV) is a promising tool for the diagnosis of early vascular remodelling and initial atherosclerotic plaque formation. Our objective was to evaluate PWV and its relationship with coronary atherosclerosis and thrombotic biomarkers in patients with SLE.

Material and methods

In 26 patients with SLE with stable clinical conditions, mean age of 39.1 ±11.7 years and without a history of coronary artery disease, multidetector computed tomography (MDCT)-based coronary calcium scoring (CACS) was performed and PWV measured.
Laboratory evaluation included serum levels of anticardiolipin and anti-β2-glycoprotein antibodies (anti-β2-GPI), lupus anticoagulant (LA), D-dimers, thrombin–antithrombin complexes (TAT), and von Willebrand factor (vWF).

Results

Multidetector computed tomography revealed coronary calcifications in 8 (30.8%) patients and the median CACS was 52.4 HU (range 2–843.2). The mean PWV was 9.0 ±3.2 m/s and was higher in patients aged > 50 years (+33.7% vs. < 50 years), those with positive LA (+28.2% vs. LA negative), TAT ≥ 10 µg/l (+18.1% vs. < 10 µg/l), vWF ≥ 200 IU/dl (+51.8% vs. < 200 IU/dl) and with coronary atherosclerosis (CACS > 0; +21.4% vs. CACS = 0).
In contrast, the duration of the disease, D-dimers, anticardiolipin, and anti-β2-GPI antibodies did not influence PWV. In the group without atherosclerosis (CACS = 0, n =18), patients with vWF ≥ 200 IU/dl had a 19.3% higher PWV compared to the rest.

Conclusions

In patients with SLE, PWV was associated with the presence of coronary atherosclerotic lesions in MDCT. Furthermore, arterial stiffness was higher in patients with markers of endothelial dysfunction and a prothrombotic state, suggesting their contribution to the early stages of arterial remodelling in SLE.

Published: July 2022

Introduction

In this study, we aimed to determine the frequency of MEFV mutations in Behçet’s disease (BD) and to investigate the relationship between clinical findings of the disease and the MEFV mutations.

Material and methods

A total of 66 participants (30 BD patients, 36 healthy subjects) were included in this study. The MEFV gene was analyzed by using DNA sequence analysis.

Results

The distribution of MEFV mutations was not significantly different between the patients and the control group (p = 0.373). However, individuals with R202Q mutation had a risk of OR 4 times (95% CI: 1.1–14.5) higher than those without the mutation (p = 0.035). The rate of vascular involvement was statistically significantly higher in patients with the mutation than in patients without the mutation (p = 0.005).

Conclusions

MEFV mutation was associated with vascular involvement in patients with BD. This is also the first study to indicate that the R202Q mutation may have a role in BD. However large series from different regions are required to compare these results.

Total hip arthroplasty (THA) is one of the most frequent orthopedic procedures worldwide and its surgical volume is constantly growing. To address the patients’ restricted access to healthcare resources and limited one-on-one contact with the surgeon during the COVID-19 pandemic, we created a reliable source of information for patients undergoing THA. The use of mHealth is increasing with access to modern technology in Poland. Information related to health issues is the second most common web search performed by older adults. Our project aimed to create the first Polish mobile application for THA patients: Endopedia.

Endopedia was developed for the Android platform based on a survey performed among patients and a collection of frequently asked questions on patients’ internet forums. The content was adapted to the elderly and visually impaired requirements. mHealth solutions should not replace one-on-one conversation, but they can provide substantial support for patients in conditions of limited information.

Poverty, Parental Ill Health and Children’s Access to Schooling in Rural Gansu, China
Authors: Hannum Emily , Sargent Tanja , Yu Shengchao
Published: July 2022

As reforms to China's health care system have raised costs to users in recent decades, studies suggest that ill health has become intimately tied to social stratification as both a precipitant and a consequence of poverty. The problem may be particularly pronounced in China’s poorest rural populations. Focusing on Gansu Province, one of China’s poorest, this paper investigates the possibility that the ill health of adults also carries cross-generational consequences, through interfering with the education of children.

Analyzing a survey of children in 100 rural villages, we find that parental illness is experienced disproportionately by the most economically vulnerable children. Moreover, parental illness can be linked to children’s educational access and experience in several ways. Children with an ill father are less likely to be enrolled than others; prior parental ill health is associated with lower household educational spending; and ill parents are more likely to report borrowing for their children’s education. Children with ill mothers are more likely to be absent and to work longer in the household. Children with ill mothers perform more poorly in math, and those with ill mothers and ill fathers are more likely to work for wages, on average, but these effects are accounted for by the deeper impoverishment of households with ill parents, compared to other households.

Results suggest that ill health may have a ‘spillover’ effect on the long-term educational (and thus economic) prospects of the next generation. A change in this situation depends heavily on the success of new government initiatives to reduce health care and education cost burdens on the poor.
Butterfingers: Resculpting Religion at a Tibetan Buddhist Monastery
Authors: Cooke Susette
Published: July 2022

For several hundred years a major Buddhist festival has been held at Kubum Monastery (Ch. Ta’ersi) in present-day Qinghai Province in the PRC. Contemporary eyewitness accounts reveal remarkable consistency in its form at least over the century preceding the founding of the current Chinese state in 1949. Evidence of changes, not from cultural imperatives within Tibetan Buddhist civilisation but under Chinese state impetus, can be perceived since the 1950's, and continue into the present.

Taking a local news item relating to the festival period as a point of entry, this paper considers representations of the festival at either end of the decade 1993-2003 in on-site experience and official reportage, a comparison which reveals several salient characteristics of the cultural-political landscape in an outlying region of the PRC. Qinghai, a large, sparsely-populated administrative unit with a rather recent history as a province, embraces several cultures and ethnic groups within its geographical bounds as well as its rhetorical identity in official discourse. The non-Chinese elements which dominated much of this frontier region before 1949 continue to present dilemmas for the state's integration project. Kubum Monastery has embodied and situated challenges among Inner Asian political forces for most of its history, a factor still utilised by the PRC in its handling of certain regional policies. In the ongoing dynamic of contested values among the region's communities at local and supra-local levels, Kubum plays both a symbolic and a substantive role. Enactions and representations of the festival - an entity itself open to variant interpretations reflecting local concerns - exemplify the state's attempts to redefine political-cultural formations of Tibetan Buddhist societies in the PRC. As an annually recurring event, the festival offers a fixed time and space for viewing this process, in particular the transforming effects of state-sponsored activities at a religious site.
Urban Growth, Rescaling, and the Spatial Administrative Hierarchy
Authors: Cartier Carolyn
Published: July 2022

After thirty years of scholarship on transformations in China under reform, accumulated research capacity demonstrates potential for increased interdisciplinary research and research questions at the interstices of fields. This paper examines one such possibility by assessing urbanization in relation to the dynamics of financial policy and rescaling through the spatial administrative hierarchy. From the perspective of the administrative hierarchy, the discussion observes the conjunctures of de/recentralization in the economy with urbanization through the establishment of new cities. Based on the work of Victor Shih on inflationary cycles, the paper demonstrates coordination of monetary policy with designation of new cities, and ultimately argues that the central government has orchestrated decentralization of economic power in association with planned urbanization as a basis of domestic growth.
From Chengdu to Stockholm: A Comparative Study of the Emergence of Paper Money in East and West
Authors: Horesh Niv
Published: July 2022

It is widely recognised that monetary paper instruments appeared in China earlier than in the West, paper itself having been invented there during the Han era. However, there have been to date few direct scholarly attempts to place the early-modern Western and pre-modern Chinese formative experiences with paper money in detailed comparison by way of attaining a better understanding of the evolution of money as a whole. This article aims to make a tentative first step toward bridging this scholarly gap. It will survey in particular the extent to which the inception of Chinese paper money in 11th-century Chengdu differed from the circumstances in which European paper money emerged. Whilst some similarity between 17th-century Stockholm and 11th-century Chengdu might arguably be traced back insofar as the emergence of paper money is concerned, British banknote issuance subsequently took on new important functions. These, in turn, ushered in our modern "national-debt" economy.
Forging Identity: Spiritual Labor as an Organizational Practice
Authors: Chappell Stacie F. , Duncan Carrie M. , LoRusso James Dennis
Published: July 2022

This paper takes McGuire's (2010) concept of spiritual labor in a new theoretical direction that departs from her tripartite framework of regulation, commodification, and codification. We begin with a review of the sparse literature on spiritual labor. Next, we describe a new theoretical framework of spiritual labor beginning with a nonessentialist definition of spirituality and then elaborating processes of discourse, organizational identification strategies, and individual identity work. We show how both organizational identification strategies and individual identity work, when infused by discourses of spirituality, mutually construct spiritual labor. Our theoretical framework is illustrated with an example. Lastly, we suggest a reflexive ethnographic method for studying spiritual labor as an organizational practice. Our reformulation of spiritual labor offers organizational scholars a way of understanding spirituality as one of many emergent properties of the organizing process. In particular, critical scholars may find the lens of spiritual labor useful for understanding how organizations enlist spirituality to induce a sense of shared purpose among organizational members.
"Carriers of Hope." Creating Organizational Spaces of Hope During COVID-19
Authors: Espedal Gry , Løvaas Beate Jelstad
Published: July 2022

In this empirical study, we aim to explore how organizations can be targets of hope during COVID-19. More specifically, we ask: how do managers create spaces of hope, and what are the underlying mechanisms facilitating these processes of hope in a crisis situation? Based on an investigation of essays written by managers prior to and during the COVID19 pandemic and drawing on analyses from a focus group interview with managers, this article shows how creating organizational spaces of hope is part of a dynamic, relational and spiritual process. The managers are working on recognizing and affirming the organizational members' situation, helping them envision hope through a process of noticing despair, searching for meaning, and creating actions of hope to establish a horizon of possibilities. This hope process is facilitated through group reflection in safe spaces as well as times of slow-thinking, enabling hope practices in organizations to be part of viewing future horizons.

Authors: Rafiq Shahid , Qaisar Shahzada , Butt Intzar Hussain
Published: July 2022

The prime aim of this research was to analyze the tools used for the teacher evaluation process in public and private universities of Lahore. The research was qualitative in its nature and follows an interpretive research paradigm. The researcher used the document analysis technique for the analysis of documents. The tools were collected by visiting the universities' concerned departments for analysis. All collected tools were reviewed and analyzed against the criteria set by four experts from the qualitative domain. It was identified that teacher evaluation tools of the private sector universities were more comprehensive and detailed and self-developed as compared to the public universities. The public sector universities were using only single-page tools. It was also pointed out that the tools of the public sector universities had very limited aspects of the teacher’s teaching, while private universities’ tools had more aspects and were exhaustive. This article might provide the source material for future researchers and policymakers to ponder the area of teacher evaluation too.
