Context

Hereditary hypophosphatemic rickets (HR) consists of a group of inherited hypophosphatemia due to mutations of different genes, which need genetic analysis to make a differential diagnosis. Among them, autosomal recessive hypophosphatemic rickets type 1 (ARHR1), caused by a homozygous mutation of dentin matrix protein 1 (DMP1), is extremely rare, with only 30 reported patients. To date, there has been no case with compound heterozygous DMP1 mutations.

Objective

To report the first compound heterozygous mutations of DMP1 causing ARHR1 and confirm the effect of the mutation on DMP1 protein.

Methods

We report the clinical features of a Chinese patient with HR. Whole-exome sequencing (WES) was performed on the proband. Then, Cytoscan HD array, Sanger sequencing, and genomic quantitative PCR (qPCR) were used to confirm the mutations. A cell experiment was conducted to explore the effect of the mutation.

Results

The proband is a 4-year-old boy, who developed genu varum when he was able to walk at age 1 year and tooth loss after a mild hit at age 3.5 years. Physical examination, biochemical measurement, and imaging finding indicated HR. Family history was negative. WES performed on the proband revealed a novel start codon mutation (c.1A > T, p.Met1Leu) in DMP1 and a large deletion involving most of the small integrin-binding ligand N-linked glycoprotein (SIBLING) family gene, including DSPP, DMP1, IBSP, and MEPE. The novel paternally inherited start codon mutation, which resulted in decreased expression of DMP1 protein with smaller molecular weight and cleavage defect, was confirmed by Sanger sequencing. The maternally inherited deletion was validated by Cytoscan and qPCR, and the breakpoint was finally identified by long-range PCR and Sanger sequencing. Manifestation of dentin dysplasia (DD) or dentinogenesis imperfecta (DGI) caused by DSPP mutations was absent in the patient and his mother, confirming that haploinsufficiency could not lead to DD or DGI.

Conclusion

We report for the first time compound heterozygous DMP1 mutations consisting of a large deletion and a novel start codon mutation (c.1A > T, p.Met1Leu) in a Chinese patient with ARHR1.

Published: November 2022

Cassava crops hold high agricultural importance in Paraná State, Brazil. However, cassava root production is adversely impacted by pests. Aleyrodids, in particular, cause great damage to cassava fields, necessitating better knowledge of predators found in these agroecosystems and novel biological control strategies for integrated pest management. This study reports the first occurrence of the predatory lady beetle Delphastus argentinicus Nunenmacher, preying on all life stages of whiteflies in cassava fields. Given the economic and social importance of cassava crops in Brazil and the deleterious potential of aleyrodid species, it is recommended to conduct behavioral and bioecological studies assessing the application of D. argentinicus as a biocontrol agent in integrated pest management programs.

Authors: Alam Noor , Siddiqui Yasir S , Abbas Mazhar , Akshay Varun
Published: November 2022

Introduction:Bicondylar Hoffa fractures are extremely uncommon injuries and there have only been a very small number of cases documented in the literature. Case Report:A 28-year-old male presented to emergency department with injury to right knee and leg. X-ray was taken; however, they were not sufficient to determine the precise fracture pattern, so computed tomography scan was done for establishing diagnosis. Fracture managed successfully using compression screws and buttress plate with satisfactory result after a follow-up period of 1 year with ROM 20–120° with no signs of Avascular necrosis or arthritis and we also discussed the appropriate treatment options with supporting literatures. Conclusion: We conclude by describing a rare case of Bicondylar Hoffa fracture managed by open reduction and internal fixation with cancellous screws and Buttress plating. All cases of unicondylar Hoffa must be evaluated with a high index of suspicion to not miss the cases of Bicondylar Hoffa, which is extremely uncommon injury.

Published: November 2022

Introduction: Congenital pseudarthrosis of tibia is an uncommon condition leading to gradually progressive deformity, shortening of the limb and disability. The condition is notorious for failure of treatment and need of multiple operations. A combination of open reduction, thorough excision of abnormal tissue at the pseudarthrosis site, intramedullary nailing, ring fixator application, and distraction to achieve bone equalization has proved successful. Case Report: A case of congenital pseudarthrosis of the left tibia and fibula associated with neurofibromatosis treated by open reduction, intramedullary nailing, ring fixator application, and distraction at corticotomy to cause compression at the pseudarthrosis site and limb length equalization is being reported due to uncommon occurrence of transient hypertension in the child as a complication of ring fixator. Conclusion: Transient hypertension is a rare complication seen in children after application of ring fixator. Its diagnosis and control require proper perioperative assessment of child regarding blood pressure (BP), monitoring of BP during distraction period and period of application of ring fixator, and its treatment under care of pediatrician.

Published: November 2022

Introduction: The present case report describes an acute reconstruction of extensor hallucis longus (EHL) tendon with defect treated using looped extensor hallucis brevis (EHB) tendon graft. Case Report: A 40 year male manual labor had an acute traumatic EHL tear which was repaired at a primary health care center. After 2 days, the patient felt a sudden click and a re-tear at zone IV of EHL. Since there was a defect of 3.5 cm which was not amenable for primary repair, EHB graft was used for the reconstruction in a loop fashion. The foot and ankle disability index score was 95.2 at 2 years follow-up with grade 4 + power. Conclusion: EHB graft is a good alternative to other autografts for extensor hallucis longus reconstructions with good clinical and functional outcomes.

Published: November 2022

Introduction: Cutaneous angiosarcoma is an uncommon aggressive tumor known to arise in chronic lymphedema of various etiologies with post mastectomy lymphedema being the most common cause also known as Stewart–Treves syndrome. Chronic filarial lymphedema is the most uncommon etiology for development of angiosarcoma. Case Report: We describe two cases of angiosarcoma developing in a setting of long-standing filarial lymphedema. The patient presented with the same clinical features of rapidly progressing nodules. Conclusion: With India harboring most of the filarial load, this scenario should be kept in mind by clinicians for early diagnosis and treatment. Angiosarcoma is a rapidly progressing tumor and is fatal; hence, an idea about its diagnosis is of utmost importance.
Abnormal Expression of an Insulin Synthesizing Enzyme in Islets of Adult Autoantibody Positive Donors
Authors: Teitelman Gladys
Published: November 2022

The observation that the two active forms of proprotein convertase 1/3 (PC1/3) were differentially expressed in beta cells of normal islets raised the possibility that this heterogeneity is lost during type 1 diabetes (T1D) progression. To test this hypothesis, the expression of the convertase was evaluated by confocal microscopy in sections of human pancreas of autoantibody positive (AA+) and T1D donors and compared with that of control. Islets of T1D pancreas were comprised of beta cells expressing either low or high PC1/3 levels and all islets of a pancreatic section contained only one beta cell type. Pancreata of AA+ donors contained either of these two classes of islets intermixed with normal islets comprised of beta cells with heterogeneous PC1/3 expression. This alteration affected the expression of proinsulin and insulin, which in most AA+ and T1D donors were lower than in controls. The present results indicate that the heterogeneity of PC1/3 expression is lost in all beta cells in a subset islets of AA+ donors and in all islets of T1D donors. These findings suggest that the heterogeneity of PC1/3 expression is a biomarker of human beta cell health and that its loss coincides with the initial stages of T1D.
»Their dogs are of an alert and intelligent breed«

Published: November 2022

This study presents a brief inquiry into the human-canine relationship among the Tyvan pastoralists in the Altai-Sayan Mountainous region of Inner Asia. Their co-evolution is intimately bound together, and the inter-species relationship includes several aspects and roles. The authors investigate especially the dogs’ responsibilities in taiga and steppe habitats and how the language reveals these responsibilities by focusing on distinctions between hunting dogs (aŋčï ït) and camp guarding dogs (kodančï ït). Both names point at the main tasks—hunting and guarding the seasonal campsite territory. The third category is named xava dogs; the name traces its origin to Chinese languages. Similarly, the story of a small-sized xava dog sheds a light on the Altai-Sayan Mountain region’s historical and religious connections with China.
An Effect of Wind Veer on Wind Turbine Performance
Authors: Tumenbayar Undarmaa , Ko Kyungnam
Published: November 2022

An investigation was performed to identify the wind veer impact on wind turbine power performance at a wind farm located on Jeju Island, South Korea. A 2 MW wind turbine was used as a test turbine. An 80 m-tall met mast was located 220 m away from the test wind turbine and a ground lidar was installed close to the met mast. The wind veer conditions were divided into four types: veering in upper and lower rotor (VV), veering in upper and backing in lower rotor (VB), backing in upper and lower rotor (BB) and backing in upper and veering in lower rotor (BV). The frequency of the four types was identified at the wind farm. The characteristics of wind veer was analysed in terms of diurnal variation and wind speed. In addition, the power curves of the four types were compared with that under no veer condition. Also, the power deviation coefficient (PDC) derived from the power outputs was calculated to identify the effect of the four types on the turbine power performance. As a result, the frequencies of the types, VV, VB, BB and BV were 62.7 %, 4.9 %, 9.2 % and 23.1 %, respectively. The PDCs for the types VV and BV were 3.0 % and 4.2 %, respectively, meaning a power gain while those for the types VB and BB were -2.9 % and -3.9 %, respectively, meaning a power loss.
Photosynthetic parameters change in Lycopersicon esculentum leaves under nutrient deficiencies
Authors: Khalid Y Alsharafa
Published: November 2022

Lycopersicon esculentum leaves cultivated hydroponically for 24 and 48 hrs with various specific mineral deficits had their photosynthetic characteristics examined. After 24 hrs of K+, NO3-, and PO42- deficiency, a substantial induction of net photosynthetic rate was observed. The net photosynthetic rate of SO42-, Mg2+, Fe2+, NO3-, Ca2+ and PO42- deficits was significantly induced by the 48 hr exposure. After 24 hrs of deficiencies in SO42-, Mg2+, Fe2+, NO3-, Ca2+ and PO42-, stomata conductance was dramatically increased. Deficiencies in SO42-, Fe2+, NO3-, Ca2+ and PO42- were continuously induced over 48 hrs. After 24 hrs of SO42-, Fe2+, NO3-, Ca2+ and PO42- deficiencies, intercellular CO2 concentration shows a considerable induction. After 48 hrs of K+, SO42-, Mg2+ and NO3-deficits, this behavior remained strongly induced. Water use efficiency considerably decreased in response to these changes after 24 hrs of SO42-, Fe2+, NO3- and PO42- deficiencies and this effect continued after 48 hrs of Mg2+, NO3-, Ca2+ and PO42- deficiencies. Deficits in K+, SO42-, Mg2+, Fe2+, NO3-, Ca2+ and PO42- for 24 hrs dramatically increased transpiration rate, which was modified by those deficiencies. A 48 hr exposure to NO3-, Ca2+ and PO42- deficiency dramatically increased the transpiration rate. After 48 hrs, an SO42- deficit drastically decreased the transpiration rate. The findings indicate that after a short term of exposure, it may be possible to diagnose a specific mineral shortage and determine which mineral influenced the parameters of photosynthesis in such a way that the selected parameters responded in a manner that was consistent with the duration of exposure.
Robust model-based control of a packed absorption column for the natural gas sweetening process
Authors: Romero-Bustamante Jorge A. , Zurita-Herrera Brenda M. , Gutiérrez-Limón Miguel Ángel , Hernandez-Martinez Eliseo
Published: November 2022

The sweetening units are the most important in natural gas processing. Packed bed absorption columns are widely used in the sweetening process; however, their operation and control are not simple due to their highly non-linear behavior derived from their distributed nature and interaction between multiple physical phenomena. In this work, two robust model-based control schemes are implemented to regulate the CO2 concentration at the outlet of a packed bed absorption column in the gas sweetening process. The model of an industrial-scale absorption column and the structure of the controllers, i) control based on modeling error compensation (MEC) ideas, and ii) nonlinear model predictive control (NMPC) are described. Numerical results show that the proposed robust model-based controllers can regulate the controlled variable to the desired reference despite external disturbances, set-point changes, and uncertainties in the absorption column model.
Sliding mode controller design based on simple closed loop set point experiment for higher order processes with dead time
Authors: Siddiqui Mohammad Atif , Nishat Anwar Md. , Haque Laskar Shahedul
Published: November 2022

In this work, a sliding mode controller (SLMC) design approach has been proposed based on second order plus dead time process (SOPDTP). The SOPDTP model of the industrial processes have been obtained by performing a simple closed-loop set-point experiment (CLSPE) having a proportional controller only. The operating procedure of SLMC comprises of continuous and discontinuous control law. The parameters of continuous control law are derived by considering SOPDTP parameters and using the root locus technique. The discontinuous control law parameters are obtained by minimizing a performance index with the help of grasshopper optimization technique. The proposed SLMC design method has been validated by considering several examples with higher order process having diverse dynamics. The performance improvement by the proposed method over the recently reported work has been observed under nominal, perturbed and noisy conditions.
Spanishlo que pasa es queand its variants in Getxo and Barcelona
Authors: Paasch-Kaiser Christine , Sinner Carsten
Published: November 2022

The Spanish constructionlo que pasa es que‘what happens is that’, ‘the thing is’ is used in a wide variety of contexts and with a range of different meanings. Linguistic research that has been carried out on this relatively common construction often fails to include empirically collected data and, as a result, the diasystematic markers thereof have only been described to a very limited extent. The main focus of this article is to investigate the use of the constructionlo que pasa es queand its phonetically reduced formslo que pasa queandlo quein two Spanish-language oral speech corpora collected in Getxo (Basque Country) and Barcelona (Catalonia). These data are used to carry out a quantitative and qualitative study of the presence or absence of this construction in both regions of language contact, something which has yet to be considered or systematically analysed in the relevant research. The study identifies a statistically relevant diatopic markedness of the formslo que pasa es que,lo que pasaandpasa quewhile also providing empirical proof for the pragmatic use of these constructions within the varieties investigated. Furthermore, it confirms the use of additional reduced forms of said constructions and describes their development.

Published: November 2022

The article examines the use ofestarin Portuguese expressions of permanent location, which runs counter to normative grammar, according to whichserandficarshould appear in those cases. This use ofestaris not mentioned in grammatical descriptions, either. Yet, it occurs in contemporary Portuguese (both Portugal and Brazil). The same goes for the Portuguese- and Spanish-lexified creoles, some of which usetá/stá(< estar),to express location. However, almost all rely on a single verb in these contexts. The research question was studied empirically in a corpus (N=1,037) based on Google searches with seven exact phrases includingestar,ser, andficar, subsequently complemented with an analysis of two other Portuguese corpora. The results show thatestarappears in expressions of permanent location, both in Portugal (22,5%) and Brazil (17,5%). However, there is a statistically significant difference,ficarbeing more frequent in Brazil andserin Portugal. Moreover, the higher frequency ofestarin Portugal may indirectly explain the popularity officarin Brazil. In addition,estarappears in written nonfiction, pointing to expressions of the typeestar localizado/situadoas its possible origin, also taking into account that no instances of its use were found in older documents.

Authors: Kapoor G. , Swaroop A. , Singh S.
Published: November 2022

Vascular stiffness due to arteriosclerosis reduces arterial elasticity which is as an independent and non-invasive predictor of future incidence of coronary heart disease and stroke. There is limited evidence of the benefits of regular exercise on arterial stiffness in populations suffering from cardiovascular diseases (CVD) especially coronary artery disease (CAD).

Aim. To determine the acute and chronic effects of aerobic, resistance and combined exercise on arterial and hemodynamic function in patients with CAD.

Material and methods. This study will be a prospective, single-blind, randomized study examining the effects of exercise on arterial stiffness. The study will be conducted at a tertiary care hospital for a continuous period of one year. Patients with CAD (n=105) will be selected using systematic sampling techniques and allocated randomly to one of the four treatment groups using computer-generated, random number sequence for age, sex and health status of CAD (Group-I: aerobic exercise, Group-II: resistance exercise, Group-III: combined aerobic and resistance exercise, and Group-IV: control) as per the inclusion and exclusion criteria. All recruited subjects will be informed about the assessment and intervention procedure before getting the consent form filled. This project followed the guidelines of standard protocol for randomized clinical trials (spirit).

Perspective. It is expected that this study protocol shall through light and be helpful in better quality of life along with decline in drug dependency for the people suffering from CAD. Further this study will be valuable is designing exercise protocol for the people suffering from CAD.

Published: November 2022

The most common cardiovascular disease (CVD) and risk factor for the main causes of death is hypertension (HTN), the prevalence of which in Russia is 44%. The combination of HTN and chronic respiratory diseases (CRDs) can lead to mutual influence and worsen the prognosis.

Aim. To study long-term outcomes in HTN patients with CRDs under outpatient monitoring in primary health care.

Material and methods. This prospective observational study of hypertensive outpatients (n=156, age, 63,4±8,8 years, men, 27,6%) was carried out, of which 49 had asthma, 20 — chronic obstructive pulmonary disease (n=69; group with CRD). The composite primary endpoint included death, myocardial infarction, cerebral stroke, transient ischemic attack, arterial revascularization, angina pectoris, peripheral arterial disease (>50% stenosis), heart failure, atrial fibrillation, and ventricular premature beats >30 h. There were following secondary endpoints: hypertensive crisis, hospitalization, emergency call and temporary disability due to cardiovascular diseases, asthma, chronic obstructive pulmonary disease, pneumonia, chronic respiratory failure. In addition, the following tertiary endpoints were analyzed: increased blood pressure (BP) without a hypertensive crisis, which required correction of HTN therapy, deterioration in CRD course (an increase in the ACQ-5 or CAT total score without exacerbation), acute bronchitis, other acute diseases and exacerbations of chronic ones, which required hospitalizations, new clinically significant chronic diseases not included in the primary and secondary endpoints.

Results. The follow-up period was 29±8 months. The groups did not differ in relation to prevalence of primary endpoints. The frequency of secondary and tertiary endpoints was higher in the CRD group due to "respiratory" events and episodes of BP destabilization requiring correction of HTN therapy (p<0,01). In HTN patients with CRDs, cumulative survival was lower, and the cumulative risk of adverse events was higher.

Conclusion. Larger studies are needed in this area, as well as an analysis of the factors associated with adverse outcomes in hypertensive patients, including BP characteristics and accounting for CRDs, in order to improve preventive approaches.

Evaluation of Extraction Conditions for Volatile Extractables from Polypropylene, PBT Resins, and Chlorobutyl Rubber Elastomers Using a Variety of Solvents and Extraction Techniques
Authors: Norwood Daniel , Fleck Louis , Seyyal Emre , Michelson Anna , Vas Gyorgy
Published: November 2022

Chemical safety assessment is one necessary step to demonstrate that the polymer used is free from harmful chemicals. The assessment should start with adequate material characterization using state-of-the-art analytical methods, including various chromatography techniques most often hyphenated with mass-spectrometric detection. Since polymers are usually incompatible with direct analysis using chromatography-based techniques, an extraction step is required prior to analytical testing. This paper provides information for practitioners who need to understand how to develop science-based extraction conditions that enable the determination of the polymer composition with respect to volatile compounds. Analytical data sets for three types of polymers (polypropylene, polycarbonate, polybutylene terephthalate, and a rubber elastomer) are presented using three different solvents and three different extraction techniques. The extracts were collected at different times during extraction and analyzed by GC-MS. The differences observed between extraction techniques, conditions, and solvents are discussed to better understand the impact of these parameters in extractable studies.

Authors: Gomes Júnior Edmilson , Bello Maria Isabela Marques da Cunha Vieira
Published: November 2022

The management of construction and demolition waste (CDW) is the main tool for construction housing sustainably. This article presents a diagnosis of the management of CDW and their environmental impacts in the municipality of Caruaru, Pernambuco. The construction and demolition waste management Index (CDWMI) was calculated. This index uses the environmental sustainability indicators: management instruments, management programs, collection and screening, and treatment and disposition of the CDW. The results of this research were compared with the results of six municipalities in the metropolitan region of Recife (MRR). The evaluation of the management of the municipality of Caruaru regarding the CDW indicated the low performance of the municipality since, of the four groups of instruments used, three of them were low grades, and only in the indicators of instruments for policies obtained the average grade. With the diagnosis of a low degree of sustainability in relation to the management of CDW, it is evident that there must be a restructuring in the management of the municipality so that what is established and agreed upon in the Municipal Solid Waste Plan (MSWP) is commenced.
“Monument” versus “dilapidation”: the discursive marking of local history as a factor of the “production of space” in Siberian cities (in the example of Irkutsk)
Authors: Timoshkin Dmitriy
Published: November 2022

The article analyzes the practices of the discursive marking of “places of memory” and their role in the construction of urban spaces of Siberian regional capitals. The author describes the areas of high-rise residential development formed in the 19th-20th centuries, defined in Russian urban narratives as the “private sector”. The latter is considered as a “nodal point” in the urban semiotic system. It is shown that some communities consider the “private sector” to be an empty space devoid of established content but which can be filled by implementing their project here. Others, on the contrary, appreciate the local history and the specifics of the place, basing alternative projects on these ideas. As a result, conflicts arise, the specifics of which become an emphasis on the theme of the past: the parties put forward different interpretations of the past and try to make them conventional. The aim of the study is to determine the role of formalized representations of local history in these processes. The article is based on 20 semi-formalized interviews with architects, public figures, local residents, officials, and entrepreneurs conducted in the period from 2017 to 2021. Using the results of these interviews, a hypothesis is formulated according to which the groups involved in conflicts tend to interpret the past as a value or a harmful anachronism, and then achieve the formalization of a version that is favorable to them. The representation of local history reflected in the normative language (the status of a “dilapidated / dilapidated building” or the status of a “cultural monument”) is used as a justification for the project to “develop” the place. The greatest success is achieved not so much by the actor who has managed to formalize the interpretation of local history that is beneficial to them, but by the one who has retained the ability to ignore the restrictions associated with the corresponding status. It creates a compromise between the formalized and informal languages of describing “memory places”, which ultimately determines their content.
James Scott and Alexander Chayanov: From the peasantry through revolutions, to the states, and anarchies
Authors: Nikulin Alexander
Published: November 2022

The author conducts a systematic comparative analysis of the scientific worldviews and key research ideas of the American political anthropologist James Scott and the Russian agrarian economist Alexander Chayanov, to show their similar interests in the study of peasant revolutions, state systems, and anarchist ideas. Based on the identified similarities and differences in the milestones of their intellectual biographies, the author compares Scott’s concept of the first ancient autarkic states with Chayanov’s abstract economic-mathematical models of island-states. The article describes the contradictions and failures of modern projects for transforming the nature and society by state bureaucracies as revealed in the studies of Scott and Chayanov, and emphasizes the interest of both scholars in the potential of the anarchist epistemological and political ideas for the development of the scientific theory and political practice of interaction between society and the state. The author argues that Scott and Chayanov are not orthodox anarchists insisting on the complete disappearance of the state; they believe that the Leviathan statehood is impossible and, perhaps, not necessary to destroy. However, in their research, both Scott and Chayanov constantly raise questions about the ways to limit and weaken the power of the state bureaucracy with various forms of non-state public life associated with the anarchist ideas of self-organization, spontaneity, and freedom.
The convergence of real and virtual communities in the digital space: a sociological review
Authors: Sharkov Felix , Kirillina Natalia
Published: November 2022

The paper represents a critical analysis of the processes caused by the development of virtual communities, and by the transfer of social practices of traditional communities into the space of interactive communication with subsequent transformations in the nature of interaction and the social roles of its participants. The authors introduce and summarize the approaches to communities such as traditional and virtual, and enunciate the distinctive characteristics of virtual and ‘real’ communities formed on the territory of geographically limited objects (villages, cities, countries), in similar conditions (historical, cultural, linguistic) and existing in a common regulatory and legal field. Based on the assumption that virtual communities are usually geographically disparate, implying significant differences in terms of historical memory, culture, native language, traditions, and other things, the authors prove that they remain communities in the sense that they unite groups of people based on common interests, goals, and views, ensuring the interaction of actors and an information exchange between them. However, the taking on the main distinctive characteristics of traditional communities, virtual communities lose some of the properties traditionally inherent in communities, such as a common territory, history, and culture. Virtual communities are defined by the authors as groups of actors interacting in a virtual space (for example, in a social network) beyond geographic and political boundaries and united by common interests or goals. They are characterized by a significant emotional involvement of the participants in the process of network interaction. In present conditions, when almost any created (and previously created) content is being digitized, real and virtual communities converge in the digital space: thus, (1) virtual communities take on some characteristics of traditional ones, and vice versa; and (2) the likelihood of adding or replacing spatial connections in real communities with virtual communications increases, which creates the convergent communities.

“Stop Beating the Dead Primordial Horse”: Actual Agendas in the Constructivist Research of Ethnicity
Authors: Varshaver Evgeni
Published: November 2022

The article describes the current state of affairs in the contemporary constructivist research of ethnicity. While emerging within anthropology in the 1960’s under the influence of sociological constructivist theories, this approach has been developing in a dialogue with “primordialism” and “essentialism”, the ways of thinking which were, to a large degree, conceptualized by constructivists themselves. It has been, however, become clearer that this dialogue is no longer productive, and constructivists faced the necessity to re-establish the very agenda of the constructivist research of ethnicity. Two projects were undertaken in the 2000-2010’s, and are associated with the names of Andreas Wimmer and Kanchan Chandra. The theoretical languages created within these projects, however, were not optimal in terms of their descriptive power. The second part of the article describes a new research program as suggested by the author, within which an alternative theoretical language is proposed, and much attention is paid to the meanings of ethnic categories as well as the social consequences of these meanings. Descriptive and analytical capabilities of the language are demonstrated from two examples taken from the empirical research of the author. The closing part of the article describes the shortcomings of the approach created, as well as the directions for further developments.
Once again about Sociology and Social Analytics in the Age of Artificial Intelligence Advancement
Authors: Rezaev Andrey , Tregubova Natalia
Published: November 2022

The article argues that the logic and prospects for resolving a continued crisis in sociology will lead social scientists to reconsider the idea of 'social analytics'. The paper advances a general view of prominent scholars about sociology being in crisis since the 1970s. It articulates the theoretical and methodological necessity of transforming sociology into social analytics in the age of artificial intelligence and artificial sociality. The paper proposes the basic characteristics and discusses essential elements of 'social analytics' as a transdisciplinary and potential anti-disciplinary academic subject. The authors assert the key components of social analytics in the principle of "three A's": •Articulate the problem. •Analyze how and what to do with it. •Argue one solution, which is nothing more than a new question. The paper argues that an explicit and systematic engagement with social analytics provides a more accurate portrayal of an unstable social world. It opens the potential for empirical and theoretical inquiry into new realities in capitalism/s development and offers a compelling alternative for challenging dominant frames for discussing the future of sociology and sociologists.
Что мы знаем о фрилансерах? Социология свободной занятости
Authors: Стребков Денис , Шевчук Андрей
Published: November 2022

В монографии рассматривается новое явление на российском рынке труда — самостоятельная занятость независимых профессионалов (фрилансеров), работающих удалённо с помощью Интернета. Сколько фрилансеров в России? Как они живут и работают? Каковы трудовые ценности и мотивация фрилансеров? В чём состоят возможности и риски свободной занятости? Каковы дальнейшие перспективы развития фриланса в России? Авторы дают ответы на эти и другие вопросы, опираясь на уникальные эмпирические данные — четыре волны масштабного мониторингового исследования ≪Перепись фрилансеров≫, охватывающего период с 2009 по 2019 год. За последнее десятилетие зафиксированы значимые изменения в социально-демографическом и профессиональном составе фрилансеров, а также формальных и неформальных принципах функционирования рынка удалённой работы, демонстрирующие активное освоение инновационной трудовой практики все более широкими слоями российских работников и высвечивающие острые проблемы на этом пути. Книга адресована не только специалистам в области социально-экономических наук, но и широкому кругу читателей, интересующихся новыми тенденциями на рынке труда.
Microwave Synthesis of Lanthanum-Doped Carbon Dots v1
Authors: Holberg Samuel
Published: November 2022

This protocol describes the synthesis of lanthanum-doped carbon dots using microwave irradiation. The complete process requires approximately 1h 50 min to complete (including baseline analysis). For this protocol, an Anton-Parr microwave reactor (Monowave 50p) was used throughout. The application example is for water quality sensing, although we have used the particles for cell imaging in other studies. ADA compliant procedures are used throughout the protocol (including both building lab space/design and analysis of synthesized particles).

From Product Platform Ecosystem to Innovation Platform Ecosystem: An Institutional Perspective on the Governance of Ecosystem Transformations

Published: November 2022

Incumbent companies across industries such as banking, insurance, and enterprise software have begun transforming their existing product platform ecosystems into innovation platforms ecosystems to increase generativity in their ecosystems. Such ecosystem transformations not only entail technological challenges as the underlying platform technology changes but also organizational challenges in that ecosystem actors such as partners and customers need to become part of the transformed ecosystem. To study how incumbent companies can govern ecosystem transformations successfully, we interpret ecosystems as organizational fields and ecosystem transformations as changes to the fields’ institutional infrastructure. Based on a multiyear, grounded theory study of the transformation of SAP’s on-premises ERP system, we first identify institutionalization challenges that arise when institutional infrastructure is changed during an ecosystem transformation. We then show how field-level governance mechanisms address these challenges and how the new institutional infrastructure gains legitimacy among ecosystem actors, ultimately leading to the institutionalization of the transformed ecosystem. These findings contribute to the literature on ecosystem transformations and platform governance by highlighting the role that institutional forces play in ecosystem transformations. Furthermore, we add to the literature on institutional theory by providing insights into the dynamics of institutional infrastructure as it becomes infused with digital technologies.
The Impact of Dominant IT Infrastructure in Multi-Establishment Firms: The Moderating Role of Environmental Dynamism
Authors: Soh Franck ,   University of North Carolina at Greensboro, Setia Pankaj ,   Indian Institute of Management
Published: November 2022

Multi-establishment firms (MEFs) rely on digitized processes enabled by advanced IT infrastructure; however, environmental dynamism is a major influence on their operations. Environmental dynamism threatens the efficacy of current operations, requiring firms to evolve their processes. Firms’ IT infrastructure may catalyze or hinder their endeavors and performance as they respond to environmental dynamics. Little previous research has examined which IT infrastructure types are high-performing and whether their effects vary across environments. We investigate the impacts of IT infrastructure, examining microlevel implementation—the constitution of technical and human assets—across the establishments of a multi-establishment firm (MEF). Specifically, we use the notion of a dominant IT infrastructure to unravel the heterogeneity of IT infrastructure across establishments. We explore dominant IT infrastructures—technology, human, or both—and assess their impacts across environmental conditions. To test our hypotheses, we used a panel dataset from 2007 to 2009 comprising 355 unique firms. Our findings reveal that the impact of establishment-level IT infrastructure types on MEF performance is contingent on environmental dynamism. A technology-dominant IT infrastructure leads to greater MEF performance in less dynamic environments, while a human-dominant IT infrastructure leads to greater MEF performance in more dynamic environments. The MEF performance is enhanced through a combination of technology- and human-dominant IT infrastructures in more dynamic environments. We conclude by discussing the theoretical insights and managerial implications of our findings.
Research Perspectives: Toward Theoretical Rigor in Ethical Analysis: The Case of Algorithmic Decision-Making Systems
Authors: Gal Uri ,   University of Sydney, Hansen Sean ,   Rochester Institute of Technology, Lee Allen S. ,   Virginia Commonwealth University
Published: November 2022

Algorithmic decision-making systems (ADMS) are increasingly being used by public and private organizations to enact decisions traditionally made by human beings across a broad range of domains, including business, law enforcement, education, and healthcare. Their growing prevalence engenders profound ethical challenges, which, we maintain, should be examined in a structured and theoretically informed fashion. However, much of the ethical exploration of ADMS within the IS field draws upon an atheoretical application of ethics. In this paper, we argue that the “big three” ethical theories of consequentialism, deontology, and virtue ethics can inform a structured comparative analysis of the ethical significance of ADMS. We demonstrate the value of such an approach through an illustrative case study of an ADMS in use by an Australian bank. Building upon this analysis, we address four characteristics of ADMS from the three theoretical perspectives, provide guidance on the contexts within which the application of each theory might be particularly fruitful, and highlight the advantages of theoretically grounded ethical analyses of ADMS.
