Transformed or Transferred? How Workers Perceive Managerial Control over Home Telework. Some Insights from an Italian Case
Authors: Iannuzzi Francesco Eugenio , Campolongo Francesco 
Published: July 2023

We examined how home-based teleworkers perceived managerial control in an Italian context in order to gain insight into some of the organizational changes brought on by the COVID-19 pandemic. Drawing on studies of changes to managerial control over the past few decades, we show how workers have experienced the reconfiguration and hybridization of control practices and methods in home telework. Our results cast doubt on the widely held belief that telework is revolutionizing managerial control and work procedures. Organizational and power dynamics at work are key to determining how telework affects employee experiences.

Summary

We investigated the impact of the COVID-19 pandemic on labour relations, specifically by examining how teleworkers perceived control within various occupations in an Italian context. Telework has long been touted as having the power to displace traditional managerial control structures in favour of less hierarchical forms of supervision. However, scholars are still divided over whether it promotes greater employee autonomy or, on the contrary, results in greater managerial control. Research has frequently been influenced by specific circumstances. In earlier decades, the low prevalence of telework encouraged neither thorough research nor the ability to compare various organizational structures. Additionally, there has been a long-standing tendency to treat teleworkers as a homogeneous group, with little regard for within-group differences. Disparities among workers and among organizations can lead to inconsistent results.
Our study was conducted mainly during the first waves of the pandemic in Italy, with a view to understanding if, how, to what extent and on what basis telework modifies managerial control processes and systems. We looked at how workers experienced managerial control in various occupations that differ in organizational form and managerial culture.
In line with Storey’s (1985) concept of “layers of control” and, more generally, with studies on transformations of managerial control in labour processes, we argue that the emergency restructuring due to home telework caused a transfer of organizational conditions, these being a combination of existing methods, standards and forms of control. Our findings show how employees dealt with the hybridization, overlapping and differentiation of various forms of control during a time of widespread telework. In this way, we cast doubt on the simplistic association between telework and reduction of control, as well as on the potential of telework to bring fundamental change to organizational processes.

Published: July 2023

Objectif de la recherche : Cet article interroge la pérennité des communautés de pratique (CoP), généralement considérée par des approches déterministes, en utilisant le cadre théorique des communs. Cet article propose donc par analogie d’analyser les CoP en tant qu’organization et organizing. Cette approche doit permettre d’identifier les conditions internes pour une reproduction d’une CoP. L’objectif de cette recherche est ainsi de comprendre les conditions d’auto-organisation et de pérennité d’une CoP. Méthodologie : Pour ce faire, nous utilisons une méthodologie mixte. Après une étude qualitative de plusieurs mois à observer et analyser deux CoP, nous nous appuyons sur une étude quantitative menée auprès de sept CoP au sein d’une entreprise, MUTUALIS. Un questionnaire permettant d’analyser l’organization et l’organizing des CoP a été envoyé aux membres. 76 réponses ont été retenues et analysées avec SMART PLS. Contribution : Si cet article identifie un potentiel de reproduction interne des CoP et donc de pérennité, il souligne également que celle-ci demeure partielle par son usage instrumental. En raison de ce dernier, les CoP minimisent leur reproduction organisationnelle et donc leur auto-organisation. Pour dépasser cette limite, le cadre du commun propose in fine une approche intégrative de l’organisation d’une action collective auto-organisée qui nous amène à penser la démocratisation à une échelle multiniveaux. Finalement, cette étude démontre l’impératif d’une transformation organisationnelle plus générale de l’entreprise qui ne peut être réduite à des dispositifs ou des communautés sporadiques.

Précis

Les communautés de pratique (CoP) semblent aujourd’hui amplement étudiées par la littérature académique depuis une vingtaine d’années, en particulier leur rôle en knowledge management. Cependant, parfois considérées comme des formes auto-organisées et émancipatrices au sein de l’entreprise, les approches traditionnellement développées concernant leur pérennité nous semblent discutables. Elles proposent en effet une conception déterministe : les CoP sont vouées à dégénérer, soit à se banaliser par contrôle de la structure managériale soit par banalisation interne. Cet article propose alors une relecture de la pérennité des CoP, à l’aide d’une approche renouvelée en sciences de gestion et non déterministe de l’action collective organisée : les communs.
Acute and Long-Term Outcomes of Hypertensive Crisis and Hypertensive Emergency in Patients Accompanied by Orthostatic Hypotension
Authors: Hayrab Chuker 
Published: July 2023

Introduction: Hypertensive crisis and hypertensive emergency are urgent medical conditions characterized by severely elevated blood pressure levels, often exceeding systolic values of 180 mmHg and/or diastolic values of 120 mmHg. The acute outcomes of hypertensive crisis and hypertensive emergency in patients with orthostatic hypotension include an increased risk of cerebrovascular events, such as ischemic and hemorrhagic strokes, as well as myocardial infarction.
Review of Literature: Orthostatic hypotension has been associated with various adverse outcomes, including syncope, stroke, CVD, and mortality. However, the effects of interventions targeting OH have yet to be extensively reported. It is important to understand the long-term outcomes in individuals with orthostatic hypotension and hypertensive episodes, but not many studies have shed light on this complex clinical scenario. The only literature available focuses on the mortality and morbidity of orthostatic hypotension rather than the outcomes of superimposed hypertensive urgency.
Discussion: The study reported secondary outcomes such as readmission rates, in-hospital mortality, stroke, acute kidney injury, and other complications. The study suggests that focusing on preventing orthostatic hypotension symptoms while tolerating some degree of supine hypertension may be a reasonable approach to management.
Conclusion: Influence the relationship between orthostatic hypotension and hypertensive emergencies. These conditions further complicate the management and outcomes of hypertensive crises and emergencies.

ImportanceBased on early studies, prurigo pigmentosa (PP) was considered a rare inflammatory dermatosis affecting primarily Asian individuals. However, several case reports subsequently showed that the disease is not restricted to those of Asian origin. Large studies on PP in central European individuals, on the other hand, are missing.ObjectiveTo increase awareness of PP by describing the clinical, histopathological, and immunohistochemical features in central European individuals.Design, Setting, and ParticipantsThis observational, retrospective case series analyzed clinicopathological features of 20 central European patients diagnosed with PP. Data collection was performed by means of archive material, including physician’s letters, clinical photographs, and histopathological records, at the Department of Dermatology at the Medical University of Graz in Austria from January 1998 to January 2022.Main Outcomes and MeasuresDemographic, clinical, histopathological, and immunohistochemical characteristics for patients diagnosed with PP were recorded.ResultsOf the 20 patients included, 15 (75%) were female, and the mean (range) age was 24.1 (15-51) years. The study cohort consisted entirely of European patients. The most common site of involvement of PP was the breast, followed by the neck and back. Other involved clinical sites were the abdomen, shoulders, face, head, axillae, arms, and genital region and groin. Clinically, lesions were characterized by a symmetric pattern in 90% (n = 18) of all cases. Marked hyperpigmentation was observed only in 25% (n = 5) of patients. In some cases, triggers such as malnutrition, long-term pressure, and friction were noted. Histologic findings revealed presence of neutrophils in all cases and necrotic keratinocytes in 67% (n = 16) of cases. Immunohistochemistry results showed predominance of CD8+ lymphocytes in the epidermis, as well as the presence of plasmacytoid dendritic cells and myeloid cell nuclear differentiation antigen–positive neutrophil precursors.Conclusions and RelevanceThis case series found that most clinical features observed in Asian patients were also observed in central European patients, but hyperpigmentation was primarily mild to moderate. Histopathological features were similar to those reported in the literature with the additional presence of myeloid cell nuclear differentiation antigen–positive precursor neutrophils. These results expand previous knowledge about PP in central European individuals.
Evaluative Morphology: Universals and Variation
Authors: Ritter Elizabeth , Wiltschko Martina 
Published: July 2023

AbstractThis entry explores the formal and distributional properties of evaluative morphology. The defining property of evaluative morphology is its interpretive function: it serves to express the speaker's evaluation of the referent (or situation) though the dimension of evaluation is not uniform: it may be related to size or attitude. The distributional properties of evaluative morphology are reviewed, and it is concluded that it does not comprise a unified morphological class. This observation has long occupied morphologists and has led to various proposals regarding the morphological classification of evaluative morphology. Most notably Scalise has proposed a ‘third morphology’ which – in terms of application of morphological rules – is situated between derivation and inflection. This approach faces the problems intrinsic to any approach which seeks to develop a unified treatment for evaluative morphology, however. It is shown that a morphosyntactic approach towards evaluative morphology can come to terms with the observed variation: evaluative morphology is not special in that it can be realized in any way in which linguistic elements can integrate to form complex expressions. Specifically, there are two parameters of variation: (i) whether a given evaluative morpheme is realized as a head or as a modifier and (ii) where in the functional hierarchy it is realized. As such, its syntactic properties in part determine its interpretive properties.

AbstractVinpocetine is a synthetic derivative of the alkaloid vincamine and has been used as a dietary supplement for decades. Following a positive report of the use of vinpocetine in a patient with a loss‐of‐function GABRB3 variant, we here describe another patient with a loss‐of‐function GABRA1 variant (p.(Arg112Gln)) who benefited from vinpocetine treatment. This patient was diagnosed with autism spectrum disorder, psychiatric complications, and therapy‐resistant focal epilepsy. Upon add‐on treatment with 40 mg vinpocetine daily for 16 months, the patient experienced an overall improved quality of life as well as seizure freedom. Our findings corroborate that vinpocetine can attenuate epilepsy‐associated behavioral issues in patients with loss‐of‐function GABAA receptor gene variants.

Published: July 2023

AbstractRoom‐temperature sodium–sulfur (RT Na–S) batteries have emerged as a promising candidate for next‐generation scalable energy storage systems, due to their high theoretical energy density, low cost, and natural abundance. However, the practical applications of these batteries are hindered by the notorious shuttle effect of soluble sodium polysulfides (NaPSs) and sluggish reaction kinetics, which result in fast performance loss. To address this issue, recent studies have reported impressive achievements of transition metal nanoparticles/single atoms/cluster/compounds (TM)‐based host materials with strong adsorption and catalyzation to NaPSs. These materials can significantly improve the electrochemical performance of RT Na–S batteries. In this review, the recent progress on TM‐based host materials for RT Na–S batteries, including iron (Fe)‐, cobalt (Co)‐, nickel (Ni)‐, molybdenum (Mo)‐, titanium (Ti)‐, vanadium (V)‐, manganese (Mn)‐, and other TM‐based materials are summarized. The design, fabrication, and properties of these host materials are comprehensively summarized and systematically analyzed the underlying chemical inhibition and electrocatalysis mechanism between NaPSs and TM‐based catalytic materials. At last, the challenges and prospects for designing efficient TM‐based catalytic materials for high‐performance RT Na–S batteries are discussed.

Published: July 2023

AbstractAqueous multivalent‐ion batteries (AMIBs) with features of environmental friendliness and cost‐efficiency are the most promising energy storage technologies for consumer electronics, electric vehicles, and grid‐scale energy storage. However, their practical application is severely impeded by the restricted capacity of electrode materials. Since chalcogen and halogen elements possess high specific capacities and low‐cost, the aqueous multivalent‐ion batteries based on chalcogen and halogen conversion are attractive due to the significant enhancement of specific energies. In this review, the advantages and recent progress of AMIBs based on chalcogen and halogen conversion chemistry have been systematically summarized with an emphasis on cell configuration, electrochemical performance, and storage mechanism. Furthermore, this review not only proposes challenges and perspectives for AMIBs, but also provides promising strategies for developing device‐scale applications. The above efforts may pave the way for the further development of high‐performance aqueous multivalent‐ion batteries with high safety and competitive performance.

AbstractThe halide perovskite CsPbBr3 belongs to the Cs‐Pb‐Br material system, which features two additional thermodynamically stable ternary phases, Cs4PbBr6 and CsPb2Br5. The coexistence of these phases and their reportedly similar photoluminescence (PL) have resulted in a debate on the nature of the emission in these systems. Herein, optical and microscopic characterizations are combined with an effective mass, correlated electron–hole model of excitons in confined systems, to investigate the emission properties of the ternary phases in the Cs‐Pb‐Br system. It is found that all Cs‐Pb‐Br phases exhibit green emission and the non‐perovskite phases exhibit PL quantum yields orders of magnitude larger than CsPbBr3. In particular, blue‐ and red‐shifted emission for the Cs‐ and Pb‐rich phases, respectively, are measured, stemming from embedded CsPbBr3 nanocrystals (NCs). This model reveals that the difference in emission shift is caused by the combined effects of NC size and different band mismatch. Furthermore, the importance of including the dielectric mismatch in the calculation of the emission energy for Cs‐Pb‐Br composites is demonstrated. The results explain the reportedly limited blue shift in CsPbBr3@Cs4PbBr6 composites and rationalize some of its differences with CsPb2Br5.

AbstractAs the core of low‐temperature direct ammonia fuel cell (DAFC) technology, electrocatalytic ammonia oxidation reaction (AOR) has proven to be most active on platinum‐based catalysts. However, the AOR is extremely surface sensitive that only the Pt (200) facet exhibits high reaction activity, whereas other facets usually do not make contributions. Herein, the inert (220) surface of PtMo nano‐alloy is successfully awakened as one more active facet in addition to (200) via directional single‐atom Ni‐doping. The introduction of Ni triggers a targeted electron accumulation around Pt sites at the (220) facet that significantly reduces the AOR energy barrier while maintaining the activity of the (200) surface. With a greatly enlarged active surface, the Ni‐decorated PtMo catalyst exhibits a significantly facilitated AOR kinetics with a low onset potential of 0.49 V versus reversible hydrogen electrode and a superior peak current density of 94.96 A g−1 at 5 mV s−1. Notably, the DAFC equipped with such an electrocatalyst reaches a remarkable peak power density of 16.70 mW cm−2 at low temperatures. It is believed that this strategy sheds light on exploiting the intrinsic activity of Pt‐based electrocatalysts, and drives the low‐temperature DAFC technology to a more practical level.

AbstractThe pandemic outbreak caused by SARS‐CoV‐2 coronavirus brought a crucial issue in public health causing up to now more than 600 million infected people and 6.5 million deaths. Conventional diagnostic methods are based on quantitative reverse transcription polymerase chain reaction (RT‐qPCR assay) and immuno‐detection (ELISA assay). However, despite these techniques have the advantages of being standardized and consolidated, they keep some main limitations in terms of accuracy (immunoassays), time/cost consumption of analysis, the need for qualified personnel, and lab constrain (molecular assays). There is crucial the need to develop new diagnostic approaches for accurate, fast and portable viral detection and quantification. Among these, PCR‐free biosensors represent the most appealing solution since they can allow molecular detection without the complexity of the PCR. This will enable the possibility to be integrated in portable and low‐cost systems for massive and decentralized screening of SARS‐CoV‐2 in a point‐of‐care (PoC) format, pointing to achieve a performant identification and control of infection. In this review, the most recent approaches for the SARS‐CoV‐2 PCR‐free detection are reported, describing both the instrumental and methodological features, and highlighting their suitability for a PoC application.
A Novel Strategy to Improve Tumor Targeting of Hydrophilic Drugs and Nanoparticles for Imaging Guided Synergetic Therapy

Published: July 2023

AbstractThe fast renal clearance of hydrophilic small molecular anticancer drugs and ultrasmall nanoparticles (NPs) results in the low utilization rate and certain side effects, thus improving the tumor targeting is highly desired but faces great challenges. A novel and general β‐cyclodextrin (CD) aggregation‐induced assembly strategy to fabricate doxorubicin (DOX) and CD‐coated NPs (such as Au) co‐encapsulated pH‐responsive nanocomposites (NCs) is proposed. By adding DOX×HCl and reducing pH in a reversed microemulsion system, hydrophilic CD‐coated AuNPs rapidly assemble into large NCs. Then in situ polymerization of dopamine and sequentially coordinating with Cu2+ on the surface of NCs provide extra weak acid responsiveness, chemodynamic therapy (CDT), and improved biocompatibility as well as stability. The subsequent tumor microenvironment responsive dissociation notably improves their passive tumor targeting, bioavailability, imaging, and therapeutic capabilities, as well as facilitates their internalization by tumor cells and metabolic clearance, thereby reducing side effects. The combination of polymerized dopamine and assembled AuNPs reinforces photothermal capability, thus further boosting CDT through thermally amplifying Cu‐catalyzed Fenton‐like reaction. Both in vitro and in vivo studies confirm the desirable outcomes of these NCs as photoacoustic imaging guided trimodal (thermally enhanced CDT, photothermal therapy, and chemotherapy) synergistic tumor treatment agents with minimal systemic toxicity.
