The relationship between pregnancies complicated with fetal growth restriction and umbilical cord blood endocan concentrations
Authors: Özgökçe Çağdaş , Uçkan Kazım , Meral Ayfer
Published: March 2022

Objectives

The main etiological factor in intrauterine growth restriction (IUGR) is the impairment of the fetoplacental unit. Due to the placental endothelial disintegrity and vascular permeability disruptions, endocan has been an interesting molecule to search for associations with IUGR. The aim of this study was to investigate the umbilical cord blood endocan concentrations in IUGR pregnancies.

Methods

This cross-sectional case-control study was conducted on 50 IUGR-complicated (patients) and 50 control pregnancies. The demographics and clinical findings were recruited from records. The umbilical cord blood was studied for endocan concentrations.

Results

The patient group compared to controls had significantly more previous IUGR history, lower maternal weight gain, an earlier gestational week at delivery, and more cesarean sections (p<0.001). The umbilical cord endocan concentrations were significantly higher in patients than in controls (p<0.001). Oligohydramnios (n=38) was significantly higher in the patients and had a significant relationship with high endocan concentrations (p<0.001). Moderate and mild positive correlations were found among endocan concentration and biparietal diameter/head circumference and femur length values, respectively, while a moderate negative correlation was observed in abdominal circumference values (p<0.001).

Conclusions

A significant increase in the umbilical cord blood endocan concentrations was found in IUGR pregnancies.

Local Christian Elites on the Public Scene in the Third Century
Authors: Pont Anne-Valérie
Published: March 2022

This article investigates the involvement of Christians in local public life before the time of Constantine through a phenomenological approach, based on the observation of behaviors and of style of interactions in public contexts. It thus explores how the practical conduct of Christian local elites acting as civic officials could be framed as conventional, in their religious group as well as in their sociopolitical milieu, with minor arrangements allowing for ease in public roles and interactions. This study consequently outlines interpretative paths regarding epigraphical evidence as well as sources less often used by historians of cities for the time preceding the legalization of Christianity. Comparing different types of sources from several areas of the empire and asserting methodological principles first exemplified by the study of an inscription from Kios (Bithynia), this study identifies a variety of behaviors by Christian local elites and of interactions with their civic environment: although barely visible, these modes of conduct emerge in the examination of sources if attention is not focused on conflictual events in the context of the persecution beginning in 303. Despite its rarity, evidence regarding Christians in local public contexts thus emerges as historically significant. This pattern of Christian participation in civic life is perceptible in some regions of the empire in the second part of the third century and reflects a specific moment in the long life of the postclassical city.
Rebel Nuns and the Bishop Historian
Authors: Casias Cassandra M. M.
Published: March 2022

This article contextualizes the letter that Radegund (c. 520–587 CE), who had been married to the Merovingian king Clothar, wrote to the bishops of Gaul to establish her new convent. Gregory of Tours preserved this letter in his account of the rebellion that erupted in Radegund’s convent two years after she died. By analyzing this letter as a tool of Gregory’s historical narrative and then evaluating it as an independent source for Radegund’s life, this paper demonstrates that Gregory’s deliberate misinterpretation of Radegund’s letter illuminates the conflict between holy women and bishops for religious influence in Late Antiquity.
A Late Antique Rural Community in Mérida
Authors: Martínez Jiménez Javier , Sastre de Diego Isaac
Published: March 2022

This paper presents the contextualized results of the latest excavations at the site of Casa Herrera (Mérida, Spain). Casa Herrera is one of the best examples of a late antique site in the Iberian Peninsula, not only because of the degree of preservation of the remains but also because of its long chronological sequence, which runs from the first to the ninth century. The excavations of the surroundings of the funerary basilica and the Roman aqueduct have unearthed the remains of a handful of buildings that could be linked to a rural monastic community from the late Roman and Visigothic periods. The site has an Umayyad phase where settlement clusters around the basilica before being finally abandoned during the ninth century.

The Hidden Ground: Native American Intercultural Relations
Authors: Rodríguez Carrión Awilda
Published: March 2022

Over the last two decades, a trend has been developing in the design community to promote social equity and emphasize the ethical responsibility of design. Community participation, programming, and post-occupancy evaluations have cemented a more democratic design process in which users, clients, and community members are given a voice to affect the final architecture product through a process called participatory design. This modus operandi becomes more vital when dealing with subcultures that historically have felt marginalized from the dominant culture. In the United States, there is great diversity among Native Americans, but our mainstream culture tends to see them as a homogeneous group, focusing on their commonalities rather than discovering and understanding individual tribal values. With the blind acceptance of generalizations about any subculture, we may miss the critical details that shape the opportunity to showcase their uniqueness and celebrate their differences. Within the studio context, what learning modalities are best to implement a participatory and constructivist learning experience? Traditionally, studio teaching with project-based design focuses on students learning formal considerations of design such as theory, environmental/structural performance, and implementation of regulatory measures. The participatory design methodology (PDM) differs in its approach by focusing on a process that emerges from all players. It does not dictate design but creates an environment that allows it to emerge through the process and interactions. The PDM process prioritizes collective synergy and creativity using participation techniques to allow for alternative solutions. In response to an inquiry by the Pawnee Native American Tribe, which invited us to investigate a proper approach to conduct design propositions within their land, this paper will report the lessons learned from the process and will exhibit alternate ways of implementing design ideas, using methodologies that expand the boundaries of academia while reaching out to native communities.
Contested Territories: Evaluating the Limits and Liberties of Design (and Designers) in Public Space
Authors: Peterson Benjamin , Warren R. Kyle
Published: March 2022

Recent accounts in Boston highlight tensions among individuals experiencing homelessness, individuals seeking treatment for substance use disorder, service providers, advocates, residents, and business owners in geographies colloquially referred to as “Mass and Cass.” The dynamic frictions of lived experience unfold in public spaces entangled in a field of social, political, economic, and spatial conditions. The Boston Architectural College, mission-driven to “provide excellence in design education emerging from practice and accessible to diverse communities,” sits less than a mile from these geographies. A curriculum in applied learning, where practicing and learning occurs concurrently, distinguishes the BAC’s educational approach from co-op or externship models. Its educational agenda recognizes the vital dialogue between academia and practice and locates teaching and learning directly within these conduits. This research-driven project focuses on the spatial, sociocultural geographies of Mass and Cass and examines the pedagogies of community participation and engagement in design education. The project addresses the nature of interdisciplinary teaching and learning in design settings through examining modes of critical thinking, listening, reflection, and translation as integral to civic spatial practices. Using the tools of spatial designers and conceptual frameworks from other disciplines, students attempt to understand the agents, actors, and forces at play in the conditions of Mass and Cass. Through critical inquiry into the sociocultural contexts that characterize the spatial narratives of Mass and Cass, students (and city agencies as collaborators) seek to identify moments when design or designers have, may have, or could have intervened in these contested territories.
Freedom and the Politics of Space: Contemporary Social Movements and Possibilities for Antiracist, Feminist Practice in U.S. Architecture
Authors: Daemmrich Chris
Published: March 2022

Students and practitioners of architecture challenge the hegemonic Whiteness, maleness, cisheteronormativity, and capitalist control of these disciplines as a means of democratizing and decolonizing practice to create conditions for Black self-determination. This paper considers how architectural professionals have responded to contemporary movements for social justice in the United States and the ways in which some are more and some less successful at addressing the intersecting nature of identity-based oppressions. Organizations and convenings, including the National Organization of Minority Architects (NOMA), Black in Design, the Design Futures Public Interest Design Student Leadership Forum, Equity by Design, and the Architecture Lobby are considered from 2012 to the pre-pandemic spring of 2020, with a focus on the emergence of new spaces and shifts in how existing spaces engage with activist movements as a result of changing political conditions. The paper provides historical background and constructive critique. It concludes with recommendations for creating institutions that respond proactively, rather than reactively, to racist violence, sexual harassment, assault, and exploitation, and for making lasting meaning of these injustices when they occur. The roles Black people and other people of color, particularly women, have played, and the roles White people, particularly men, and White institutions must play in creating an antiracist, feminist architecture are a focus of this paper.
The Architecture Curriculum Between Two Revolutions: From the West to the Islamic Curriculum
Authors: Javid Ali
Published: March 2022

The architectural curriculum in Iran has been changed five times in the last five decades (1963–2017). In each period, efforts to change the content and structure of the curriculum were based on the architectural profession’s vision with regard to sociopolitical and economic issues, such as the agenda of development in the White Revolution and Islamizing the society after the 1979 Islamic Revolution. The curriculum as a sociopolitical artifact can be defined as a systematic set of relations between people, objects, events, and circumstances that is changed and developed based on the sociopolitical agenda. This paper focuses on crucial moments in the transformation of architectural education between the two contemporary revolutions in Iran, the White Revolution and the Islamic Revolution. The story of the transformation of the curriculum began in 1963 when a new system of architectural education, Italian pedagogy, was brought to Iran and decolonized the curriculum from the previous pedagogy system, Beaux-Arts, and it continued until the Cultural Revolution (1980–1984), when the new Islamic government decided to detoxify the curriculum from Western influence to Islamize it. This paper outlines the transformation of the structure and content of the architecture curriculum to adapt to the sociopolitical agenda of each revolution.
Coalition Building and Discomfort as Pedagogical Strategies
Authors: Vallerand Olivier
Published: March 2022

Innovative design solutions come from inclusive and diverse design teams (Page 2008). In this paper, I reflect on how such insights can be used in developing pedagogical approaches that use coalition building, knowledge translation between disciplines, and pedagogies of discomfort to foreground implicit biases impacting architectural practice and education. Based on interviews with educators thinking about the built environment, as well as Kevin Kumashiro’s (2002) anti-oppressive education framework and Megan Boler’s (1999) notion of a pedagogy of discomfort, and building on examples from queer and feminist educators, I suggest in this paper that the disruptive use of feelings and emotions in architectural education can prepare students for more collaborative and inclusive practices. Such discussions allow students to understand the impact of biases but also to think about tools to acknowledge and challenge inequity in the design of the built environment and in the design professions themselves. Cross-disciplinary collaboration, at both the students and the educators level, can also create opportunities for coalition building, particularly in contexts where a limited number of faculty are explicitly discussing race, gender, disability, class, sexuality, or ethnicity in their teaching. Faculty members with diverse individual self-identifications can multiply their impact by working together to tackle the intersecting ways in which minoritized experiences are pushed aside in mainstream architecture discourses and education. They can also foreground their combined experiences as positive role models to create a constructive learning environment to address these issues, both within universities and directly in the community.
The Natural Rate of Interest Through a Hall of Mirrors
Authors: Rungcharoenkitkul Phurichai , Winkler Fabian
Published: March 2022

Prevailing explanations of persistently low interest rates appeal to a secular decline in the natural interest rate, or r-star, due to factors outside monetary policy's control. We propose informational feedback via learning as an alternative explanation for persistently low rates, where monetary policy plays a crucial role. We extend the canonical New Keynesian model to an incomplete information setting where the central bank and the private sector learn about r-star and infer each other's information from observed macroeconomic outcomes. An informational feedback loop emerges when each side underestimates the effect of its own action on the other's inference, possibly leading to large and persistent changes in perceived r-star disconnected from fundamentals. Monetary policy, through its influence on the private sector's beliefs, endogenously determines r-star as a result. We simulate a calibrated model and show that this `hall-of-mirrors' effect can explain much of the decline in real interest rates since 2008.
Moldy Lemons and Market Shutdowns
Authors: Chang Jin-Wook , Darst R. Matthew
Published: March 2022

This paper studies competitive market shutdowns due to adverse selection, where sellers post nonexclusive menus of contracts. We first show that the presence of the worst type of agents (moldy lemons) causes markets to fail only if their mass is sufficiently large. We then show that a small mass of moldy lemons can lead to a large cascade of exits when buyers possess outside options. Finally, we show that more precise information about agents' types makes markets more prone to exit cascades. The model is general and does not rely on institution details or structure, and thus can be applied to many different markets and context.
A Stock Return Decomposition Using Observables
Authors: Knox Benjamin , Vissing-Jorgensen Annette
Published: March 2022

We propose a method to decompose stock returns period by period. First, we argue that one can directly estimate expected stock returns from securities available in modern financial markets (using the real yield curve and the Martin (2017) equity risk premium). Second, we derive a return decomposition which is based on stock price elasticities with respect to expected returns and expected dividends. We calculate elasticities from dividend futures. Our decomposition is an alternative to the Campbell-Shiller log-linearization which relies on an assumption about the log-linearization constant. An application to the COVID crisis in 2020 reveals that risk premium changes drove much of the crash and rebound in the S&P500 while a fall in long-term real yields drove a strong positive return for 2020 as a whole.
Development of indicators to assess waste management sustainability at construction sites in the city of Recife, Brazil
Authors: Maria Lucena da Fonsêca Walberlena , Antônio Maia Lins Eduardo , Henrique Fernandes da Paz Diogo , De Castro Pessoa Melo Daniele , Lee Barbosa Firmo Alessandra
Published: March 2022

Civil construction activities promote a considerable increase in waste generation which negatively impacts the environment. Although there are sustainable technologies and practices for reusing these wastes, the disposal and inappropriate destination of these wastes still prevails. Faced with this problem, this article presents a development of indicators to assess sustainability at construction sites. Thus, 30 sustainability indicators related to solid waste management at construction sites were prepared, divided into six matrices, and related to construction management, documentation control, waste segregation and initial conditioning, waste transport and final conditioning, final destination and hazardous waste management, as based on CONAMA Resolution no. 307/2002. The indicators composed six sub-indices to enable assessing sustainability and the composition of a final sustainability index. The diagnosis of the result by group of indicators shows that the focus on waste transport and final conditioning obtained the highest sustainability degree by the projects studied, while the lowest degree of sustainability presented by the projects was observed in the construction waste segregation and initial conditioning matrix.
Physician Compliance with Nutrition Support Team Recommendations: Effects on the Outcome of Treatment for Critically Ill Patients
Authors: Yon Hyon-Ju , Oh Eun-Suk , Jang Ji Young , Jang Ji Yun , Shim Hongjin
Published: March 2022

Purpose: Attending physicians in Korea are aware of the existence of the Nutrition Support Team (NST), but even when the NST are consulted, compliance with their recommendations may be low. This study was performed to identify physicians’ compliance with the NST advice and how this affected the outcome of treatment for critically ill patients.Methods: This study was a retrospective observational study. Critically ill patients who were older than 18 years, younger than 90 years, and had been admitted and managed in the intensive care unit were selected for this study. Patients were assigned to either the compliance group or the non-compliance group according to physician compliance with the NST advice. Each group were compared using variables such as calorie supply, protein supply, laboratory findings, hospital stay, 30-day mortality, and survival rate.Results: The compliance group (81% of cases) was supplied with a significantly higher energy (1,146.36 ± 473.45 kcal vs. 832.45 ± 364.28 kcal, p < 0.01) and a significantly higher protein (55.00 ± 22.30 g/day vs. 42.98 ± 24.46 g/day, p = 0.04) compared with the non-compliance group. There was no significant difference in the basic demographics between groups, although the compliance group had a better outcome in the 30-day mortality rate (8% vs. 26%, p = 0.02), and in survival beyond 1 year (Crude model, hazard ratio: 2.42, CI: 1.11-5.29).Conclusion: Critically ill patients whose attending physician complied with the NST advice, received an increased energy intake and supply of protein which was positively associated with survival.
Lost Dental Bridges During ICU Stay
Authors: Kim Ji Hye , Lee Jae-myeong
Published: March 2022

Oral care is easily neglected in patients in an intensive care unit (ICU) because they are often intubated or have altered mental status. Although care workers pay careful attention to the mouth, tooth loss often occurs in the ICU. Here we report 3 cases of dental bridge loss undetected by the ICU staff. One patient was under mechanical ventilation via an endotracheal tube after emergency intubation, whilst 2 patients were drowsy but not intubated. Consecutive chest X-rays revealed dental bridge loss in all 3 cases, but this was not identified immediately. Along with other critical management approaches, these cases demonstrate how an initial evaluation of the oral cavity, with special attention to the number of teeth, and the existence of dental prosthetics is essential to preventing potential deleterious complications. The number of teeth and the existence of dental prosthetics must be documented in ICU patients.

Authors:   School of Mechanical Engineering/Institute of Vehicles and New Energy Technology, North China University of Water Resources and Electric Power, Zhengzhou City, Henan, China, Xu Jianlun , Wang Minghao , Guo Ping
Published: March 2022

With the large consumption of traditional primary energy, hydrogen as a clean and renewable energy has been widely studied by scholars around the world. Hydrogen is mainly used in hydrogen internal combustion engine and hydrogen fuel cell. Hydrogen internal combustion engine is the direct combustion of hydrogen as fuel, with the advantages of easy use. Alternatively, hydrogen fuel cell converts the chemical energy of hydrogen into electrical energy by electrochemical reaction, which has the advantages of high efficiency and zero pollution. Regardless of the use method, the safety of hydrogen use needs to be considered. However, in the whole life cycle of hydrogen, the process from hydrogen production to the use of hydrogen in automobiles is extremely complex. There are many factors affecting the safety of hydrogen use, and a single factor cannot be used as an evaluation. In order to make the evaluation of hydrogen safety more complete and accurate, the weight of four primary evaluation indexes and eight secondary evaluation indexes affecting hydrogen safety is determined by analytic hierarchy process, and a reliable hydrogen safety evaluation model is established.

The article provides a quantitative analysis of online language courses located on such online platforms as Coursera, Udemy, Edx and Alison. Communicative and linguistic competencies are necessary characteristics of an active citizen who interacts effectively with the surrounding society. Also, in the conditions when the internationalization processes are increasing knowledge of a foreign language becomes very important. Massive open online courses (MOOC) are considered to be a promising and powerful means of language training. Today, they have combined the possibilities provided by the Internet, the quality content, and the best teaching practices. We have found that MOOC can be used for distance and blended learning, as well as in the process of self-education. When designing online language courses for MOOC you should consider certain criteria and requirements. The topics of the online courses, level of complexity, quality educational content, practical orientation, interactivity, availability of feedback, etc. are of special importance. We found that the analyzed platforms have several identical functional features: multilingual interface, a possibility to choose the language of courses, a possibility to obtain a certificate, the availability of links to related courses, the availability of headings, a possibility to search for courses by keywords. In total, we identified 5,159 online courses for learning 21 languages. The Udemy platform has the largest number of online language courses (4,270 courses). The most popular languages appeared to be English (1,760 courses), Spanish (544 courses), French (451 courses), and Chinese (450 courses). The least popular languages, which are represented by only one online course, are Swedish, Latin, Noongar, and Tibetan. We found that such online platforms as Coursera and Edx provide courses that give users an opportunity to obtain a professional certificate, specialization, or a degree.
Assessment of effectiveness of fetal medicine foundation calculator in predicting risk for preterm preeclampsia using first trimester mean uterine artery pulsatility index and maternal factors in Indian population
Authors: A Anil , Varghese V. Binoj , John Afra
Published: March 2022

Background: Preeclampsia (PE) is a hypertensive disorder of pregnancy associated with significant maternal morbidity and mortality. The outcome of the disease depends to a large extent on risk factors, maternal vascular responsiveness, screening performance and prevention effectiveness. Fetal medicine foundation has developed an online calculator that predicts the risk for PE in pregnant woman in first trimester using MUAPI (mean uterine artery pulsatility index) and maternal factors.Methods: Diagnostic test evaluation of FMF (fetal medicine foundation) calculator done using data collected from consenting 316 women with singleton pregnancy between the gestational age 11 weeks to 14 weeks+1 day who fulfilled inclusion and exclusion criteria. All cases were followed up and results were analyzed statistically.Results: FMF calculator predicted a high-risk population of 12 pregnant women. On follow up of 316 subjects 13 pregnant women developed preterm preeclampsia with an incidence of 4.1%. Among high-risk population 9 subjects developed preterm PE and among the 304 cases in low-risk group 4 patient developed preterm PE. In this study sensitivity of FMF calculator was 69.2% and specificity was 99% with a PPV of 75, NPV of 98.6, positive likelihood ratio of 69.9 and diagnostic odds ratio of 225. The area under ROC was 0.841 with 95% CI (0.711-0.972) was high indicating that the algorithm was able to differentiate between pregnant women at high or low risk for preterm PE.Conclusions: This study concludes that the algorithm used in FMF calculator in first trimester is highly specific and have high sensitivity for predicting preterm PE and can be used in routine clinical practice to identify women at high risk.
A study of the diagnostic effectiveness of repeated fine needle aspiration in thyroid and breast lesions
Authors: S. Anju , S. Sheeja , Thambi Renu , Sundaram Sankar
Published: March 2022

Background: Fine needle aspiration cytology (FNAC) is a relatively safe diagnostic tool with high sensitivity and specificity. Due to lesion inherent properties and lack of proper technique, adequate cellularity is not yielded in some instances, resulting in an inconclusive report. In such instances we have to go for repeat FNA to make a proper diagnosis. Repeat aspirations impose unnecessary workload on the lab and are distressful to the patients. The issue of repeat aspiration is largely unaddressed. Objectives were to identify the proportion of repeated fine needle aspirations in breast and thyroid lesions turning out to be diagnostic and to identify and describe the common factors leading to repeat fine needle aspiration.Methods: 190 cases of repeated FNA including both thyroid and breast lesions are included in the study. FNA done after an initial aspiration with inconclusive smear is considered as repeated FNA. History, clinical examination findings, findings in imaging studies, nature of aspirate obtained for each patient advised repeat FNA, are recorded. Proportion of repeat FNAs turning out to be diagnostic and the documented reasons for repeat were taken as the outcome measure.Results: 78% of repeat FNA in thyroid lesions and 50% of the repeat FNA in breast lesions were diagnostic. Inadequate cellularity, haemorrhagic aspirate and cystic change are the most common factors leading to repeat FNA.Conclusions: Since thyroid and breast are the most common sites where FNA is done and 64% of the total lesions are diagnostic, repeat FNA in all other sites are likely to yield a similar diagnostic outcome. Hence, repeat FNA is advisable in lesions which had initial non diagnostic result.

Esophageal duplication cysts are congenital anomalies of the foregut, occurring due to aberration of the posterior division of the embryonic foregut at 3-4 wk gestation. These inherited lesions usually diagnosed in early childhood and rare in adult age group. We are reporting this case as esophageal duplication cyst in an adult female patient which is masquerading as hydatid cyst of liver. We are reporting one case of esophageal duplication cyst in a adult patient which is a rare condition to occur in this age group and managed successfully by laparoscopic approach. Esophageal duplication cyst, though it is a rare condition, should keep in mind ason of the differential diagnosis for the cystic lesions arising from gastroesopahegal junction. It can be managed by laparoscopic approach.
Macroeconomic Impact of Oil Price Shocks on Government Expenditure and Economic Growth in Nigeria

The Nigerian economy depends on over 90% oil exports revenue to drive government expenditure aimed at supporting growth-enhancing fiscal investments. Oil price has therefore become the standard benchmark for estimating aggregate annual revenue projections for all fiscal budgets and overall prospects of budgetary success. Over the years, growth in oil exports revenue and associated growth in government expenditure supported by macroeconomic policy reforms have failed to diversify the economy away from its mono-cultural revenue base. This paper investigated the nexus between oil price shocks, government expenditure and economic growth in Nigeria for the period 1986 to 2018, an era marked by bold market reforms. Generalized Methods of Moments (GMM) and Vector Error Correction (VECM) techniques are used for the empirical examination of the relationship between the study variables. The results indicate a direct and significant relationship between oil price and both government expenditure and economic growth. The exchange rate and exports channels are the intermediaries that transmit oil price shocks to the economy. Similarly, findings have confirmed evidence of the Dutch Disease in Nigeria. Given the ongoing decarbonization of global energy, the study provides recommendations for an urgent shift in growth policy focus away from dependence on oil revenue to bold reforms that will fast-track fiscal and exports revenue diversification and sustainability, anchored on private sector initiatives.
Sustainable HRM Practice and Organisational Excellence: An Empirical Analysis
Authors: Aro-Gordon Stephen , Mohamed Al-Raeesi Fatima Yaqoob
Published: March 2022

The paper rethinks the role of sustainable human resource management practices in achieving corporate excellence, using the case of Oman, an emerging Arab Gulf economy currently pursuing an economic diversification strategy tagged Oman Vision 2040. The paper is based on the survey data collected from 212 workers and managers working in the nation’s capital city, Muscat, between December 2020 and February 2021. The respondents were randomly surveyed across Oman Vision 2040’s priority economic diversification agenda sectors: investment management, infrastructure, energy, banking, and telecommunication. The analysis includes 22 data points covering essential HRM practices, including recruitment, compensation, motivation, organisational training, and learning and development. The IBM Statistical Package for Social Sciences (SPSS) was used for the data analysis. Descriptive statistics and hypothesis testing of Karl Pearson’s r correlation, emphasising the p-value < 0.01 interpreted to be highly significant at a 1% significance level, are presented. Adopting HRM as a strategic partner in a business model significantly impact organisational excellence, especially concerning staff training and appraisal system. However, while country-specific factors might influence the HRM practice in the domestic context, the expected association between Omani strategic HRM factors, such as labour laws, expatriate workforce, and foreign education and organisational excellence, may not be supported by the current empirical evidence. The research also found a weak correlation between job performance and employee appraisal systems. This paper used survey data from human beings, workers and HRM managers, whose responses might be open to distortions; further research is required to confirm these results using multiple data sources. The need to encourage creativity and innovation in job performance through continuous on-the-job training and development leveraging technology and data analytics applications is acknowledged. The implications for rethinking SHRM practices and policies towards developing a new intrapreneurial, well-motivated, adaptive, and trained workforce are documented. Human capital’s adequacy and quality have been widely recognised as critical to any organisation's value-creation goal. Still, research to date is somewhat inconclusive on what the priority HRM practices should be in the contemporary fast-paced, technology-driven business environment. This research makes a theoretical and empirical contribution to scholarly discussions on the role of SHRM practices in modern organisations. It also adds value to SHRM research and practice. The present research may be the first Oman-specific SHRM study with empirical perspectives from the Covid-19 pandemic.
Simulation modeling of urban power grid operation mode

Certain variable factors can impact reliability and efficiency of power grids. In this paper, we investigated contribution of variable factors into operation of urban power grid in the city of Dushanbe, Tajikistan, as an example. An indicator reflecting some specific reasons of uneven phase loads in power grids during peak hours was offered. A simulation model was built in Matlab and typical scenarios of power consumption were analyzed. The simulation results verified that a power grid operation mode is subject to change depending on considered variable factors.
Ocena homogeniczności regionów w Polsce z punktu widzenia struktury wieku ludności
Authors: Majdzińska Anna
Published: March 2022

Miasta, zwłaszcza te pełniące funkcję stolicy województwa, stanowią istotny element każdego regionu, zarówno pod względem gospodarczym, społecznym, jak i demografia siła ich polaryzacyjnego oddziaływania często sięga poza administracyjne granice regionu. Celem opracowania jest ocena homogeniczności (lub dywergencji) województw z punktu widzenia struktury wieku populacji, a także ocena stopnia podobieństwa struktury wieku populacji zamieszkującej powiaty do tejże struktury mieszkańców stolic wojewódzkich. Analizy poprzedzone zostały charakterystyką województw Polski oraz ich stolic w latach 2002 i 2018 z punktu widzenia struktury wieku ludności, ze szczególnym uwzględnieniem procesu starzenia się populacji. Następnie dla danych z 2018 r., przy wykorzystaniu metody Warda, przeprowadzona została klasyfikacja powiatów leżących w granicach województw których stolicami są największe pod względem liczby mieszkańców miasta oraz województw Polski Wschodniej. Dokonano też oceny podobieństwa powiatów leżących na obszarze wymienionych województw do ich stolic pod względem struktury wieku ludności w 2018 r. Uzyskane rezultaty wykazały większą homogeniczność regionów Polski Wschodniej pod względem podobieństwa powiatów leżących w ich granicach do stolic poszczególnych województw z punktu widzenia struktury wieku ludności, niż regiony których stolicami są największe pod względem liczby ludności miasta.
Pułkownik Ludowego Wojska Polskiego, czyli o przemilczeniach w narracji biograficznej
Authors: Rawski Tomasz
Published: March 2022

Artykuł podejmuje problematykę przemilczeń w narracjach biograficznych funkcjonariuszy aparatu władzy PRL. Stanowi studium strategii unikania opowieści o okresie Polski Ludowej, a jego podstawą jest czternastogodzinny wywiad narracyjny z emerytowanym pułkownikiem Ludowego Wojska Polskiego. Autor proponuje kontinuum strategii unikania, które rozciąga się od prób odpolitycznienia własnego uczestnictwa w systemie, poprzez strategię minimalnych ustępstw, do prób zdjęcia z siebie odpowiedzialności za uczestnic­two w strukturach władzy. Zdaniem autora, może ono stanowić przyczynek do stworzenia modelu – przydatnego narzędzia zwiększającego efektywność badań nad funkcjonariuszami poprzedniego systemu. Kontinuum jest jednocześnie propozycją rozpoczęcia namysłu nad problemem przemilczeń biograficznych, pojawiającym się w badaniach biograficznych nad wspomnianą grupą. Problem ten wydaje się szczególnie istotny ze względu na konsekwentne negowanie okresu PRL w polskim dyskursie publicznym.
