Objectives

To identify genes that are related to delayed endolymphatic hydrops (DEH) in patients by RNA‐Seq analysis.

Design

Observational study.

Setting

Eye & ENT Hospital, Fudan University (Shanghai, China).

Participants

We collected the entire vestibular system from four patients with DEH who underwent labyrinthectomy. Three control samples were collected from patients with acoustic neuroma or facial neuroma treated via the translabyrinthine approach. High‐throughput RNA‐Seq analysis was performed to investigate gene expression in the pathological vestibular system.

Main outcome measures

Our bioinformatic analysis identified 17 genes that were upregulated and eight genes that were downregulated in patients with DEH compared with the controls.

Results

The altered gene expression profile suggested that DEH is closely related to neuropathy and autoimmune disease. In addition, many of the differentially regulated genes were involved in cell adhesion, suggesting a role of cell adhesion in DEH. Immunofluorescence analysis confirmed the expression of PMP2 and CLDN19 in the cytoplasm of hair cells and scattered expression of MPZ at cell junctions. The protein expression levels were higher in specimens from patients with Ménière's disease and DEH compared with controls.

Conclusions

The protein expression profile of vestibular organs in patients with endolymphatic hydrops exhibited a degree of similarity to that of Ménière's disease. Endolymphatic hydrops is characterised by autoimmune abnormalities. DEH and Ménière's disease are likely to be different manifestations of the same disease, with disparate clinical symptoms. RNA‐Seq is a useful analytical tool to characterise the vestibular pathology based on its transcriptome.
Effect of structural relaxation on crystal nucleation in a soda‐lime‐silica glass
Authors: Rodrigues Lorena R. , Abyzov Alexander S. , Fokin Vladimir M. , Zanotto Edgar Dutra
Published: March 2021

The influence of structural relaxation on crystal nucleation has been underexplored and remains elusive. This article discusses its possible effect on the nucleation process using a stoichiometric soda‐lime‐silica (2Na2O·CaO·3SiO2) glass as a model system. We show that the relaxation effect is powerful at low temperatures, close and below the glass transition, , and leads to a continuous increase in the nucleation rate. At any given temperature, the nucleation rate eventually reaches its ultimate steady‐state corresponding to the fully relaxed supercooled liquid (SCL). However, the time to reach the steady‐state is two to three orders of magnitude longer than the average relaxation time estimated by the Maxwell relation (shear viscosity / shear modulus). The proposed nucleation mechanism and model, which take relaxation into account, and related experimental results also explain the alleged “breakdown” of CNT at low temperatures reported for various glasses. It confirms a few recent papers that this apparent flaw is merely because most researchers did not prolong nucleation treatments enough to complete the relaxation process to achieve a steady state. Another remarkable result is that the actual maximum nucleation temperature, , is significantly lower than the previously reported values. Finally, a comparative analysis of the kinetic coefficient using viscosity versus growth velocity favors the last. These results for this soda‐lime‐silica glass extend and validate recent findings for lithium disilicate on the significant (but often neglected) effect of relaxation on crystal nucleation.
MicroRNA‐122 promotes apoptosis of keratinocytes in oral lichen planus through suppressing VDR expression
Authors: Ge Xuejun , Xie Hanting , Wang Lu , Li Ran , Zhang Fang , Xu Jing , Zhao Bin , Du Jie
Published: March 2021

MicroRNA‐122 (miR‐122) is known to be up‐regulated by inflammation to exert a variety of biological functions in hepatocellular carcinoma (HCC)‐derived human cell lines. Vitamin D receptor (VDR) is reported to regulate excessive oral keratinocytes apoptosis which compromises oral epithelial barrier in oral lichen planus (OLP). Although many studies have suggested that miR‐122 is capable of regulating cell apoptosis, its effects on the development of OLP and VDR expression are still unclear. Herein, we demonstrate that miR‐122 expression is increased in the epithelial layer of OLP. Mechanically, transcription factor nuclear factor‐κB (NF‐κB) selectively binds with κB element in the promoter of miR‐122 to accelerate gene transcription. The up‐regulation of miR‐122 induces cell apoptosis in human oral keratinocytes (HOKs) by targeting VDR mRNA. In VDR knockout oral keratinocytes, miR‐122 fails to improve caspase 3 activity and cleaved caspase 3 and poly(ADP‐ribose) polymerase (PARP) levels. Moreover, VDR overexpression is able to reverse lipopolysaccharide (LPS)‐ or activated CD4+ T cell–induced miR‐122 up‐regulation and ameliorate miR‐122‐stimulated caspase 3 activity. Collectively, our results suggest that miR‐122 promotes oral keratinocytes apoptosis in OLP through decreasing VDR expression.
Plant addition impact on aflatoxin B1 levels, physico‐chemical, nutritional, and sensory properties of fried peanut biscuits
Authors: Gard Camille , Kolich Chong Maria Alejandra , Sawadogo Yamkaye Aïcha , Moreau Lydie
Published: March 2021

Aflatoxin B1 is a mycotoxin that can be present in peanut‐based products, such as fried peanut biscuits, if Good Agricultural Practices are not respected. Impact of plant powder presence on aflatoxin B1 levels was investigated in contaminated peanut biscuits. It was observed that adding 2% of Moringa oleifera powder led to a significant (p < .05) reduction of the toxin after 3 hr of contact time in the dough before the frying step. The toxin level reduction was estimated at 17%. The addition of moringa powder can also have some nutritional benefits. It doubled the content of iron and calcium in the biscuits, leading to products that could bear a claim “source of” for 100 g of biscuits. There was almost no loss of those minerals during the frying step. β‐carotene content is a nutrient present in moringa powder, unfortunately the losses during the frying step were estimated at 78%, probably due to the molecule migration from the biscuit to the frying bath. Adding 2% moringa powder in fried peanut biscuit could present safety and nutritional benefits, however, consumer acceptance should be studied as the color as well as the peanut smell and flavors were significantly impacted (p < .05). It is recommended to pursue the investigation of the role of moringa powder onto the toxin degradation to understand the mechanism behind and assess the toxicity of the secondary molecules generated.

First steps to integrate general palliative care into a cardiac hospital setting – using dialogue‐based workshops
Authors: Roikjær Stine Gundtoft , Timm Helle , Simonÿ Charlotte
Published: March 2021

Background

Heart failure is a chronic, life‐threatening illness with multiple acute events. Palliative care alongside standard treatment is recommended for these patients. There is a lack of knowledge and research literature on how to integrate palliative care interventions for heart failure patients in a general hospital setting.

Aim

The aim of this study was to produce new insight for developing and integrating general palliative care into heart failure treatment.

Methods

Guided by action research, we conducted an interdisciplinary workshop inspired by Tsoukas dialogue theory, where tension between perspectives is used as a facilitator of dialogue and the generation of new insights. Perspectives were incorporated through selected patient narratives and professionals’ experiences. Data from the workshop were analysed using a thematic analysis. The findings are interpreted with Kleinman's theory on illness and disease and discussed using Tsoukas theory and additional research.

Results

General palliative care must be initiated from the patient's perspective and wishes. Doing so requires understanding and uniting the different perspectives and objectives of heart failure treatment and palliative care. One way of doing this is through a narrative approach with interdisciplinary teams. However, this requires organisational efforts and adaptation to the specific cardiac setting.

Conclusion

Integrating palliative care principles into cardiology is a complex issue. Developing palliative care for heart failure patients requires more than simply designing a set of guidelines. Rather, a wider outlook involving perspectives, competences and organisation is necessary. Acknowledging such considerations, we designed an intervention centred on three elements: standard heart failure treatment, integrated sessions applying a narrative approach and monthly interdisciplinary conferences.

Relevance

This article adds to the current research literature on changing palliative care practice for heart failure patients and the value of integrating different perspectives.

A Short-Gage-Length Extensometer and Its Application to the Study of Crankshaft Stresses
Authors: Gadd C. W. , Van Degrift T. C.
Published: March 2021

The mathematical methods of determining elastic stresses in machine elements, particularly those of irregular contour, may be excessively complex, so resort is frequently made to approximate calculations, which tend to lose accuracy while achieving simplicity. As a result a constant effort is made to supplement the mathematical treatment with experimental methods of studying stress. In this paper, the authors describe a short-gage-length extensometer and explain its application in the determination of crankshaft stresses. This instrument meets the requirement of convenience in operation, which is so essential in assuring that it will be used for the study of localized stresses.
The Photoelastic Analysis of Transverse Bending of Plates in the Standard Transmission Polariscope
Authors: Drucker D. C.
Published: March 2021

In this paper the ideas of three-dimensional photo-elasticity are applied to the analysis of plates under transverse bending, resulting in a simple photoelastic method, employing the standard two-dimensional transmission polariscope. The procedure used is to “freeze” a fairly high initial tension in bakelite or similar material, cut out the model at some angle to the direction of the tension, bend, and observe. Results of various tests are given; photographs of two cases, the circular hole and the semicircular notch, are included. Stress-concentration factors are also obtained and analyzed. The problem of the thick plate as contrasted with the thin plate, assumed in the usual theory, is discussed briefly.
Photoelastic Separation of Principal Stresses by Oblique Incidence
Authors: Drucker D. C.
Published: March 2021

Rotation of a two-dimensional model about an axis in its plane is suggested as a simple and quite rapid means of obtaining p and q separately. A determination of retardation (fringe order) in an oblique position is all that is required in addition to the usual photoelastic measurements. Experimental and theoretical evidence is presented to show that accurate results can easily be obtained when the principal stress is of significant magnitude. The method can also be applied in three-dimensional studies.
Failure From Creep as Influenced by the State of Stress
Authors: Siegfried W.
Published: March 2021

As early as 1912, it was pointed out by Rosenhain and Ewen (1) that the behavior of metals at high temperatures could be explained by the combined action of the crystals and the so-called grain boundaries. This theory was also made use of later to explain problems in connection with creep phenomena (2). The author discusses subsequent studies in the United States and Germany, relating to the occurrence of brittle fractures in metals after long periods of time. With the aid of the Rosenhain-Ewen conceptions, he attempts to reconcile discrepancies between recent observations on the occurrence of inter-crystalline fractures after long test periods. His evaluation of the theories cited offers an explanation of various phenomena which previously could not be interpreted, and also furnishes a basis for determining the risk of failure with creep in a three-dimensional system of stress. He concludes that the problem of calculating the strength of a material subjected to creep is actually solved only when the metallurgist and the steel manufacturer are in a position to furnish the designer with complete experimental data enabling him to predict failure for all systems of stress occurring in practice.

Matrix-Product Codes over Commutative Rings and Constructions Arising fromσ,δ-Codes
Authors: Boulagouaz Mhammed , Deajim Abdulaziz
Published: March 2021

A well-known lower bound (over finite fields and some special finite commutative rings) on the Hamming distance of a matrix-product code (MPC) is shown to remain valid over any commutative ringR. A sufficient condition is given, as well, for such a bound to be sharp. It is also shown that an MPC is free when its input codes are all free, in which case a generator matrix is given. IfRis finite, a sufficient condition is provided for the dual of an MPC to be an MPC, a generator matrix for such a dual is given, and characterizations of LCD, self-dual, and self-orthogonal MPCs are presented. Finally, the results of this paper are used along with previous results of the authors to construct novel MPCs arising fromσ,δ-codes. Some properties of such constructions are also studied.

Published: March 2021

Serverless computing is growing rapidly due to its rapid adoption by the cloud providers and tenants in terms of its scalability, elasticity, flexibility and ease of deployment. Such increase in deployment of serverless computing makes the research to rethink on its security aspects.
Since, the serverless security computing may undergo problems due to malicious users or hackers. In this paper, a secure and an efficient access control system is designed for serverless security computing for both knowledge and resource sharing using attributed based encryption. Initially,
the data is encrypted using user attributes; further the data is split into cipher text. It is finally decrypted using a decryption algorithm and then the shares of the cipher text are distributed in the network and the encapsulated texts are stored in the serverless system. The performance
on security analysis shows that the proposed method achieves improved data security in serverless environment than the existing methods.

Published: March 2021

In recent days, content based image retrieval (CBIR) becomes a hot research area, which aims to determine the relevant images to the query image (QI) from the available large sized database. This paper presents an optimal hybrid feature extraction with similarity measure (OHFE-SM) for
CBIR. Initially, histogram equalization of images takes place as a preprocessing step. Then, texture, shape and color features are extracted. The texture features include Gray Level Co-Occurrence Matrix (GLCM) and Gray Level Run Length Matrix (GLRLM) is extracted, where the optimal number
of features will be chosen by whale optimization algorithm (WOA). Afterwards, the shape feature extraction takes place by Crest lines and color feature extraction process will be carried out using Quaternion moments. Finally, Euclidean distance will be applied as a similarity measure to determine
the distance among the feature vectors exist in the database and QI. The images with higher similarity index will be considered as relevant images and is retrieved from the database. A detailed experimental validation takes place against Corel10K dataset. The simulation results showed that
the proposed OHFE-SM model has outperformed the existing methods with the higher average precision of 0.915 and recall of 0.780.

We firstly discover the enhanced catalytic activity of magnetic noble metal nanoparticles mediated by surface plasmon resonance. Under light irradiation with certain wavelength, the catalytic performance of magnetic noble metal nanoparticles shows changes with different degrees and
directions that are associated with the surface plasmon resonance (SPR) of the noble metal. Moreover, the coupling of silver and gold allows the catalytic performance of magnetic bimetallic Ag–Au nanoparticles to show more positive response to surface plasmon resonance. The magnetic
bimetallic Ag–Au nanoparticles show excellent catalytic performance toward the reduction reaction of aromatic nitro group, and corresponding rate constant of the catalytic reduction reaction increases about three times with light irradiation.

Modeling the Effects of Crop Rotation and Tillage on Sugarbeet Yield and Soil Nitrate Using RZWQM2
Authors: Anar Mohammad J. , Lin Zhulu , Ma Liwang , Chatterjee Amitava
Published: March 2021

Highlights

Four crop growth modules in RZWQM2 were calibrated for four sugarbeet rotation sequences.

Sugarbeet following wheat had a slightly higher yield (3% to 6.5%).

Moldboard plow increased sugarbeet yield by 1% to 2%.

The difference in N losses under different crop rotations and tillage operations was negligible.

Abstract. Sugarbeet (Beta vulgaris) is considered to be one of the most viable alternatives to corn for biofuel production as it may be qualified as the feedstock for advanced biofuels (reducing greenhouse gas emission by 50%) under the Energy Independence and Security Act (EISA) of 2007. Because sugarbeet production is affected by crop rotation and tillage through optimal use of soil water and nutrients, simulation of these effects will help in making proper management decisions. In this study, the CSM-CERES-Beet, CSM-CERES-Maize, CROPSIM-Wheat, and CROPGRO-Soybean models included in the RZWQM2 were calibrated against experimental field data of crop yield, soil water, and soil nitrate from the North Dakota State University Carrington Research Extension Center from 2014 to 2016. The models performed reasonably well in simulating crop yield, soil water, and nitrate (rRMSE = 0.055 to 2.773, d = 0.541 to 0.997). Simulation results identified a non-significant effect of crop rotation on sugarbeet yield, although sugarbeets following wheat resulted in 3% to 6.5% higher yields compared to other crops. Net mineralization and N uptake rates were slightly higher when sugarbeets followed wheat compared to the other crops. Seasonal N and water mass balances also showed lower N and water stresses when sugarbeets followed wheat. The effects of tillage operations on sugarbeet yield were also non-significant. The difference in the N losses to runoff and drainage from the sugarbeet fields under different crop rotations and tillage operations was negligible. As sugarbeet production may be expanded into nontraditional planting areas in the Red River Valley due to potential demand for biofuel production, our findings will help to assess the associated environmental impacts and identify suitable crop rotations and management scenarios in the region.

Published: March 2021

In the context of COVID-19 pandemic, we aimed to analyze the epidemiology, clinical characteristics, risk factors for mortality and impact of COVID-19 on outcomes of solid organ transplant (SOT) recipients compared to a cohort of non transplant patients, evaluating if transplantation could be considered a risk factor for mortality. From March to May 2020, 261 hospitalized patients with COVID-19 pneumonia were evaluated, including 41 SOT recipients. Of these, thirty-two were kidney recipients, 4 liver, 3 heart and 2 combined kidney-liver transplants. Median time from transplantation to COVID-19 diagnosis was 6 years. Thirteen SOT recipients (32%) required Intensive Care Unit (ICU) admission and 5 patients died (12%). Using a propensity score match analysis, we found no significant differences between SOT recipients and non-transplant patients. Older age (OR 1.142; 95% [CI 1.08–1.197]) higher levels of C-reactive protein (OR 3.068; 95% [CI 1.22–7.71]) and levels of serum creatinine on admission (OR 3.048 95% [CI 1.22–7.57]) were associated with higher mortality. The clinical outcomes of SARS-CoV-2 infection in our cohort of SOT recipients appear to be similar to that observed in the non-transplant population. Older age, higher levels of C-reactive protein and serum creatinine were associated with higher mortality, whereas SOT was not associated with worse outcomes.

COVID-19 is a global threat with an increasing number of infections. Research on IgG seroprevalence among health care workers (HCWs) is needed to re-evaluate health policies. This study was performed in three pandemic hospitals in Istanbul and Kocaeli. Different clusters of HCWs were screened for SARS-CoV-2 infection. Seropositivity rate among participants was evaluated by chemiluminescent microparticle immunoassay. We recruited 813 non-infected and 119 PCR-confirmed infected HCWs. Of the previously undiagnosed HCWs, 22 (2.7%) were seropositive. Seropositivity rates were highest for cleaning staff (6%), physicians (4%), nurses (2.2%) and radiology technicians (1%). Non-pandemic clinic (6.4%) and ICU (4.3%) had the highest prevalence. HCWs in “high risk” group had similar seropositivity rate with “no risk” group (2.9 vs 3.5 p = 0.7). These findings might lead to the re-evaluation of infection control and transmission dynamics in hospitals.
The Conceptualization of Explicit and Implicit Populism in Donald Trump’s Twitter Communication
Authors:   , Tóth Tamás
Published: March 2021

A disszertáció legfontosabb céljai között szerepelt az explicit és implicit populista politikai kommunikációs stílus definiálása és tesztelése. Mintaként a 2016-os egyesült államokbeli választások során egymással versengő Donald Trump és Hillary Clinton twitteres üzeneteire fókuszáltam. A dolgozat komparatív módszertannal rendelkezik: egyfelől, 2016 szeptember 1-től 2016 november 8-ig elemzi a fenti két ágens kommunikációját, másfelől, a Donald Trump választási győzelmét követő közel fél esztendő során keletkezett tweetjeit hasonlítja össze a kampány tweetjeivel.
Coronavirus and Effects on the Rule of Law
Authors: Sessa Carmelina
Published: March 2021

In the management of the Coronavirus Pandemic, law is called to play a synergistic role with the science to guarantee the public order and safety. In the European context Italy is to be examined, i.e. the first state in Europe to launch containment measures of the spread of the virus and to protect public health.

Through a comparative approach, the purpose here is to examine the assumptions and the impact of the emergency legislation on the Italian democratic system. Evaluating within what limits fundamental human rights and freedoms’ compression can be legitimated on a national and international basis in exceptional events allow to analyse the relative reflections on the rule of law. Finally, the discussion focuses on the compatibility of using mass surveillance technologies on the International and European regulatory framework where balancing techniques and the principle of proportionality represent the core in framing the regulatory activity. Despite undoubted short-term benefits, the concern is to safeguard both the protection of personal data and health, in the face of this 'invisible enemy', considering that the link between emergency regulation and prolonged compression of rights in technological innovation requires special attention.
Vitamin D, Falls and Balance Capacity Impacts in Older Adults: Update
Authors: Marks Ray
Published: March 2021

Background Falls injuries continue to contribute to numerous premature deaths as well as high disability levels, and excess morbidity rates among older adults, worldwide. But can vitamin D account for excess falls injuries among older adults? This review specifically focuses on what is known about vitamin D in the context of postural stability or balance control, both fairly consistent independent predictors of falls among older adults. Methods and Procedures Drawn largely from a review of current relevant English language peer reviewed research publications published over the last 10 years detailing the relationship between vitamin D levels and balance control among the elderly, as this relates to falls injuries, evidence for any emerging consensus on this controversial topic was sought. Used to conduct the search were various key word combinations including: falls injuries and older adults, vitamin D or vitamin D deficiency and balance or postural control. The database used predominantly to provide input into this largely descriptive assessment and narrative overview was PUBMED. Results The prevailing data show falls injuries currently constitute a widespread costly major impediment to successful aging and longevity for many older adults, despite numerous efforts to prevent this disabling set of events over the past two to three decades. However, no consistent association appears to exist between the variables of vitamin D, falls, and balance attributes in the older population-despite years of research, regardless of study approach, and a strong rationale for hypothesizing a clinically meaningful relationship. Conclusion It is not possible to arrive at any universal recommendation concerning the value of vitamin D supplementation as regards its possible influence on balance capacity among older adults in the realm of falls prevention efforts, as has been frequently proposed. However, until more definitive research is conducted, there still appears sufficient justification for considering the screening of vulnerable aging adults for serum vitamin D levels, along with balance impairments, and intervening as required in the case of deficits in either or both of these possible falls determinants.
Polityka Unii Europejskiej wobec nieregularnej imigracji
Authors: Trojanowska-Strzęboszewska Monika
Published: March 2021

Zapobieganie i zwalczanie nieregularnej imigracji było jednym z zasadniczych celów unijnej polityki imigracyjnej, od uzyskania przez UE kompetencji w tej dziedzinie. I chociaż na gruncie tej polityki imigracja nieregularna definiowana jest szeroko i obejmuje zjawiska dotyczące nielegalnego wjazdu, tranzytu oraz pobytu imigrantów w państwach członkowskich, UE zdecydowanie skoncentrowała swoje wysiłki na eliminowaniu nielegalnego wjazdu. W tym celu podejmowano działania w obszarach bezpośrednio z tym związanych, jak zwalczanie przemytu i walka z handlem ludźmi, a także takich, które stopniowo wykształciły własną logikę polityk szczegółowych jak: zarządzanie granicami zewnętrznymi, polityka wizowa czy polityka azylowa. Oznaczało to, że od początku aktywność UE wobec imigracji nieregularnej była rozproszona i stanowiła elementy kilku szczegółowych polityk, strategii i planów działania. Kryzys migracyjny lat 2015–2016 jedynie nieznacznie zweryfikował unijne podejście do nieregularnej imigracji. Priorytetem nadal pozostało eliminowanie nieregularnego wjazdu poprzez walkę z przemytem (prowadzoną środkami kontroli granic zewnętrznych z wykorzystaniem nawet instrumentów polityki bezpieczeństwa i obrony), przy wzmocnieniu wysiłków na rzecz drugiego celu, jakim stało się zwiększenie realizacji powrotów imigrantów, którzy nie uzyskali zgody na pobyt w państwach członkowskich. Ponadto, unijna uwaga w większym stopniu została też zwrócona w kierunku eliminowania pierwotnych przyczyn nieregularnej imigracji. W tym zakresie UE postawiła przede wszystkim na różne instrumenty polityki zewnętrznej, by współpracować z krajami pochodzenia i tranzytu imigrantów.
Relacje zewnętrze Unii Europejskiej w dziedzinie kultury. Słabości polityki
Authors: Gierat-Bieroń Bożena
Published: March 2021

Polityka zagraniczna UE w dziedzinie kultury jest stosunkowo nowym i mało zbadanym obszarem działalności UE. Jej funkcjonowanie określił traktat z Lizbony, nakładając nań kompetencje programująco-inicjatywne oraz reprezentacyjne Wysokiego Przedstawiciela Unii do spraw zagranicznych i bezpieczeństwa (WP), ESDZ oraz delegatur UE. Dyplomację kulturalną UE prowadzą również – na zasadzie partnerstwa z Unią – instytuty kultury państw członkowskich, zarejestrowane w Stowarzyszeniu Narodowych Instytutów Kultury Unii Europejskiej (EUNIC) oraz ich klastry regionalne. Artykuł ma za zadanie prześledzić w trybie analiz ewolucji priorytetów zawartych w relacjach zewnętrznych UE w dziedzinie kultury (a także analiz instytucjonalnych) oraz zweryfikować, czy instrumenty polityczne zastosowane wobec soft power UE są wystarczające dla efektywnego kształtowania wizerunku kulturowego Europy w świecie. Tezą niniejszego artykułu jest twierdzenie, że relacje zewnętrzne UE w sektorze kultury odznaczają się słabą polityką, dlatego nie mają szans osiągnąć fazy dojrzałości, tym samym tworzyć trwałych podstaw do cywilizacyjnego oddziaływania kultury europejskiej, rozumianej w sposób integracyjny, czyli jako realizacja paradygmatu „jedności w różnorodności”.
Isoglosses and language change: Evidence of the rise and loss of isoglosses from a comparison of early Greek and early English
Authors: Lavidas Nikolaos
Published: March 2021

We analyze the rise and loss of isoglosses in two Indo-European languages, early Greek and early English, which, however, show considerable distance between their structures in many other domains. We follow Keidan’s approach (2013), that has drawn the attention on the fact that the study of isoglosses (i.e., linguistic features common to two or more languages) is connected with common innovations of particular languages after the split into sub-groups of Indo-European: this type of approach aims at collecting isoglosses that appear across the branches of Indo-European. We examine the rise of the isogloss of labile verbs and the loss of the isogloss of the two classes of aspectual verbs in early Greek and early English. Our study shows that the rise of labile verbs in both languages is related to the innovative use of intransitives in causative constructions. On the other hand, the innovations in voice morphology follow different directions in Greek and English and are unrelated to the rise of labile verbs. In contrast to labile verbs, which are still predominant for causative-anticausative constructions in both languages, the two classes of aspectual verbs are lost in the later stages of Greek but are predominant even in Present-day English. Again, a “prerequisite” change for the isogloss can be easily located in a structural ambiguity that is relevant for aspectual verbs in early Greek and early English. However, another independent development, the changes in verbal complementation (the development of infinitival and participial complements) in Greek and English, determined the loss of this isogloss.
Social Support and Psychological Adjustment Among College Adults
Authors: Wesley Rachel , Booker Jordan A.
Published: March 2021

Introduction: We were interested in building on previous studies showing the promotive and buffering roles of social support for emerging adults. We tested the associations of multiple domains of social support (i.e., family, friends) with measures of adjustment and adversity.

Methods: Across four studies, U.S. college adults reported on domains of social support (family, friends, significant other), psychological adjustment (i.e., life satisfaction, flourishing), and psychological adversity (i.e., recent stress, depressive symptoms). Studies 1 and 4 were cross-sectional, whereas Studies 2 and 3 involved two, monthly survey reports. Study 4 was completed against the backdrop of early COVID-19 disruptions for college adults in the Spring of 2020.

Results: In each study, each domain of social support was positively correlated with measures of adjustment and negatively correlated with measures of adversity. Partial correlations indicated that support from friends was incrementally associated with nearly every outcome, whereas support from family was incrementally associated with a majority of outcomes. Multiphase studies supported unidirectional, but not bidirectional, effects from earlier adjustment onto later social support.

Discussion: Overall, findings reinforce the importance of social support for young adults and highlight the distinct importance of family and friends. Findings also suggest that a lack of perceived social support may contribute to risks fitting views such as the stress generation theory among emerging adults.
The Future of an Illusion: The Problem of Sovereignty
Authors: LaMothe Ryan
Published: March 2021

The author explores the idea of sovereignty as an illusion that is and will continue to have deleterious effects on cooperative efforts to slow or stop climate change and the extinction of millions of species. To make this case, the notion of sovereignty is defined and its attributes described. This lays the foundation for arguing, from a psychoanalytic perspective, that sovereignty is a tightly held illusion (and practice). The last section of the article identifies the negative present and future impact of sovereignty with regard to the Anthropocene Age, as well as briefly identifying other possibilities for ordering societies.
