A trust-driven privacy architecture for vehicular ad-hoc networks
Authors:   , Serna-Olvera Jetzabel Maritza
Published: July 2023

Vehicular Ad-Hoc NETworks (VANETs) are an emerging technology which aims to improve road safety by preventing and reducing traffic accidents. While VANETs offer a great variety of promising applications, such as, safety-related and infotainment applications, they remain a number of security and privacy related research challenges that must be addressed.
A common approach to security issues widely adopted in VANETs is the use of Public Key Infrastructures (PKI) and digital certificates in order to enable authentication, authorization and confidentiality. These approaches usually rely on a large set of regional Certification Authorities (CAs). Despite the advantages of PKI-based approaches, there are two main problems that arise, i) the secure interoperability among the different and usually unknown- issuing CAs, and ii) the sole use of PKI in a VANET environment cannot prevent privacy related attacks, such as, linking a vehicle with an identifier, tracking vehicles ¿big brother scenario" and user profiling. Additionally, since vehicles in VANETs will be able to store great amounts of information including private information, unauthorized access to such information should be carefully considered. This thesis addresses authentication and interoperability issues in vehicular communications, considering an inter-regional scenario where mutual authentication between nodes is needed. To provide interoperability between vehicles and services among different domains, an Inter-domain Authentication System (AS) is proposed. The AS supplies vehicles with a trusted set of authentication credentials by implementing a near real-time certificate status service. The proposed AS also implements a mechanism to quantitatively evaluate the trust level of a CA, in order to decide on-the-y if an interoperability relationship can be created. This research work also contributes with a Privacy Enhancing Model (PEM) to deal with important privacy issues in VANETs. The PEM consists of two PKI-based privacy protocols: i) the Attribute-Based Privacy (ABP) protocol, and ii) the Anonymous Information Retrieval (AIR) protocol. The ABP introduces Attribute-Based Credentials (ABC) to provide conditional anonymity and minimal information disclosure, which overcome with the privacy issues related to linkability (linking a vehicle with an identifier) and vehicle tracking (big brother scenario). The AIR protocol addresses user profiling when querying Service Providers (SPs), by relying in a user collaboration privacy protocol based on query forgery and permutation; and assuming that neither participant nodes nor SPs could be completely trusted.
Finally, the Trust Validation Model (TVM) is proposed. The TVM supports decision making by evaluating entities trust based on context information, in order to provide i) access control to driver and vehicle's private information, and ii) public information trust validation.

Strategies for Conserving Military Heritage for Tourism: The Case of Ghana Navy
Authors: Attah Emmanuel Yaw
Published: July 2023

This study explores the heritage of Ghana since its inception after the Second World War (WW II). It identifies and examines tangible and intangible assets that comprise this heritage in relation to various strategies adopted by Ghana Navy to protect and conserve these heritage assets for posterity. Research on military heritage in Ghana is very scanty due to the peculiar character, rules, regulations and professional activities of the Armed Forces particularly the Ghana navy. The restrictive nature of the naval installations coupled with inadequate technical knowhow in conservation practices prevents the Ghana from fully availing themselves to other sources and forms of conservation strategies and practices. Furthermore, there is a limit to the extent members of the public engage with them to learn about their heritage. Qualitative method was used to gather primary and secondary data. Using ethnographic and other anthropological research methods and techniques, primary data was gathered from active naval personnel and naval veterans while secondary information was obtained from archival, library and other literary sources. The study discovered that Ghana Navy has been built through many years of experience, customs and traditions of the state to achieve an objective of providing protection at the sea and inland water bodies. The Ghana navy’s heritage encompasses tangible attributes and intangible attributes which constitute the bedrock around which the institution revolves. This study contends that documenting naval heritage is one of the important strategies to promote heritage tourism in Ghana.
Comprehensive Study of Cellulosic and Synthetic Membranes for Dialyzer
Authors: Patil Divya , Balivada Santosh , Gorde Satyam
Published: July 2023

The kidney is the primary osmoregulatory organ in the mammalian body, removing harmful wastes such as ammonia and excess fluid from the blood and maintaining the ionic concentrations of the blood by retaining electrolytes, calcium, and phosphorus. In kidney failure, the kidneys are unable to filter the blood effectively. Dialysis is a survival treatment for patients with kidney failure. Dialysis involves the exchange of blood and dialysate across a semipermeable membrane. Concentration gradients drive diffusion, and hydrostatic pressure gradients drive convection. There are two different types of dialysis: peritoneal and hemodialysis. During hemodialysis, the blood is filtered by an external device called a dialyzer. Since the 1950s, dialyzers have been used commercially for hemodialysis; their removal capacity of uremic substances, biocompatibility, and combination of glomerular and renal tubular function have all been the subject of ongoing development. Despite the progress, mortality remains high. Investigating how dialysis membranes affect long-term morbidity and mortality in hemodialysis maintenance patients is essential. Dialyzer membranes play a vital role in dialysis treatment. Important characteristics of membrane material include permeability, hydrophilicity, and biocompatibility. Cellulosic and synthetic polymeric membranes are the two primary types of dialysis membranes. This article comprehensively analyzes the concept of dialysis and the characteristics of dialyzers and their types. This review focuses critically on the membranes of the dialyzer and their classification. We anticipate that this review will aid researchers in selecting the optimal dialyzer and membrane material to improve hemodialysis treatment outcomes for renal disease patients.
If Fascism Is Not Really On the March, Then Why the Constant ‘Brown Scares’?
Authors: Bar-On Tamir
Published: July 2023

¿Qué es exactamente el fascismo? Los fascistas se veían a sí mismos como creadores de la unidad entre el capital y el trabajo y el fascismo como una ideología revolucionaria antiliberal, anticomunista y anticonservadora, que mezcla ideales ultranacionalistas antiliberales y marxistas revisionistas, y que nació durante las múltiples crisis de los años de entreguerras. Es un tipo de "socialismo" en nombre de la nación, que supuestamente renace tras un periodo de decadencia y declive. Los fascistas son, por tanto, anticapitalistas (y anticomunistas) y, por extensión, "antimaterialistas". Pretenden crear una comunidad nacional unificada, que no se vea desgarrada por las divisiones de las desigualdades capitalistas ni por el enfrentamiento comunista entre burguesía y proletariado. Los fascistas consideran que el liberalismo, el sistema parlamentario y los legados igualitarios y de derechos de las revoluciones estadounidense y francesa son individualistas y, por tanto, antitéticos a la causa primordial de la nación.

Today “Brown Scares” are the order of the day in many countries in Europe and the Americas. Why is this the case in anti-fascist age when fascism is not really on the march? I want to advance the argument that there are few fascists remaining today in Euro-American societies, but that “Brown Scares” have been revived in various decades since the 1950s. These “Brown Scares” are used by the establishment to undermine political opponents and to engage in more authoritarian mechanisms against enemies of the current pro-liberal and pro-capitalist establishment.
Ex Oriente lux. El rechazo de Occidente y sus consecuencias sociales y políticas
Authors: Mansilla H. C. F.
Published: July 2023

Today in an important portion of the Third World it is usual to believe that the philosophical thinking, the practical wisdom, and the right political doctrine have been not originated in Western Europe, but in Africa and Asia. In the 19th century the romantic movement started a new and positive vision about the Orient in order to establish an alternative to the detested Western rationalism. Today this vision praises above all the historical, political, and economic function of the Chinese civilization, which now is reaching the level that it had always deserved. The dangerous aspect of this doctrine lies in the fact that by means of very popular arguments it lets fall the positive aspects of Western modernity: rationalism, pluralistic democracy, and the conception of human rights.

En buena parte del Tercer Mundo se cree hoy que el pensamiento filosófico, la sabiduría práctica y la doctrina política correcta no se han originado en Europa occidental, sino en África y Asia. En el siglo XIX el movimiento romántico inició una visión nueva y positiva acerca del Oriente para establecer una alternativa al detestado racionalismo occidental. Hoy esta visión enaltece ante todo el rol histórico, político y económico de la civilización china, que ahora estaría alcanzando el nivel que siempre le correspondió. Lo peligroso de estas teorías es que mediante argumentos muy populares dejan a un lado lo positivo de la modernidad occidental: el racionalismo, la democracia pluralista y la concepción de los derechos humanos.

Published: July 2023

Long-beaked common dolphin (Delphinus delphis bairdii) distribution is limited to the Eastern North Pacific Ocean. Its whistle repertoire is poorly investigated, with no studies in the Gulf of California. The aim of the present study is to characterize the whistles of this species and compare their parameters with different populations. Acoustic monitoring was conducted in La Paz Bay, Gulf of California. Recordings were inspected in spectrogram view in Raven Pro, selecting good quality whistles (n = 270). In the software Luscinia, contours were manually traced to obtain whistle frequencies and duration. Number of steps, inflection points and contour type were visually determined. We calculated the descriptive statistics of the selected whistle parameters and we compared the results with a dolphins population from the Eastern Pacific Ocean. Permutational multivariate analysis of variance (PERMANOVA) was performed to test the intraspecific variation of the whistle parameters among groups. In the present study the mean values (±SD) of the whistle parameters were: maximum frequency = 14.13 ± 3.71 kHz, minimum frequency = 8.44 ± 2.58 kHz and duration = 0.44 ± 0.31 s. Whistles with the upsweep contour were the most common ones (34.44%). The coefficient of variation (CV) values for modulation parameters were high (>100%), in accordance with other studies on dolphins. Whistle parameters showed significant differences among groups. Finally, ending and maximum frequencies, duration and inflection points of the whistles recorded in the present study were lower compared with the parameters of the long-beaked common dolphins from the Eastern Pacific Ocean. This study provides the first whistle characterization of long-beaked common dolphin from the Gulf of California and it will help future passive acoustic monitoring applications in the study area.

Published: July 2023

Taken the unlimited Na reservoir worldwide, battery technology based on Na‐ion chemistry poses as an ideal candidate for large‐scale energy storage systems. Especially, with metallic Na replacing traditional carbon anodes, it's able to maximize the energy density inexpensively. Nevertheless, sodium metal batteries (SMBs) face intrinsically poor stability due to their highly‐reactive nature, where low Coulombic efficiency and short lifetime are often witnessed. The situation can be further aggravated at low temperatures due to insurmountable kinetic barriers. Herein, a 1,3‐dioxolane‐based quasi‐solid‐state electrolyte (PDGE) is proposed with a high ionic conductivity of 3.68 mS cm−1 even at −20 ◦C for SMBs. Moreover, a weak solvation environment is tailored by PDGE, which possesses a high Na+ transference number of 0.7. Concurrently, the solid electrolyte interphase induced from PDGE presents inorganic Na2O, NaF as the major components, which offers accelerated Na+ diffusion and superior stability upon long‐term cycling. With such a quasi‐solid‐state electrolyte, the Na/Na3V2(PO4)3 full cell exhibits great stability over 1000 cycles at −20 ◦C. This study has significant implications to the development for SMBs under low‐temperature conditions.
An engineered interleukin‐11 decoy cytokine inhibits receptor signaling and proliferation in lung adenocarcinoma

Published: July 2023

The cytokine interleukin (IL)‐11 has been shown to play a role in promoting fibrosis and cancer, including lung adenocarcinoma, garnering interest as an attractive target for therapeutic intervention. We used combinatorial methods to engineer an IL‐11 variant that binds with higher affinity to the IL‐11 receptor and stimulates enhanced receptor‐mediated cell signaling. Introduction of two additional point mutations ablates IL‐11 ligand/receptor association with the gp130 coreceptor signaling complex, resulting in a high‐affinity receptor antagonist. Unlike wild‐type IL‐11, this engineered variant potently blocks IL‐11‐mediated cell signaling and slows tumor growth in a mouse model of lung cancer. Our approach highlights a strategy where native ligands can be engineered and exploited to create potent receptor antagonists.

Published: July 2023

The internal Xe gas pressure of ultrafine bubbles has been directly measured for the first time by using the γ‐γ angular correlation technique, a well‐known measurement technique in nuclear physics. Radioactive 125Xe (T1/2 = 16.9 h) was induced inside natural Xe‐ultrafine bubbles in water, having an average diameter of 200 nm, by thermal‐neutron irradiation. The asymmetry factor for the 55–188 keV γ‐γ cascade in 125I, followed by the β decay of 125Xe, was used as a probe for the gas pressure in ultrafine bubbles. The internal pressure of the ultrafine bubbles was determined to be  × 105 Pa, lower than those for ultrafine bubbles of N2, CH4, and Ar by Ohgaki (6 × 106 Pa) or that from the Young‐Laplace equation (1.6 × 106 Pa).

Published: July 2023

Incomplete removal of micropollutants in wastewater treatment leads to contamination of the aquatic environment. Mixed‐matrix membranes with different shares of embedded adsorbents are considered promising for the elimination of commonly found pharmaceuticals. However, their ideal geometry and reusability after a loading cycle remain uncertain. In this study, the life cycle of loaded membranes could be extended through chemical regeneration with ethanol at different temperatures. Moreover, membrane stability and adsorbent‐to‐membrane‐area ratio could be enhanced through a seven‐bore geometry.
Global stability of a SEIR discrete delay differential‐difference system with protection phase
Authors: Adimy Mostafa , Chekroun Abdennasser , Kuniya Toshikazu , Meghelli Hanene
Published: July 2023

We consider an epidemiological model with the four classical compartments of susceptible, exposed, infected, and recovered population. We add a new compartment that is supposed to describe, for a limited time, individuals that are protected from the epidemic through vaccination or medication, for instance. We model the protection phase by an age‐structured partial differential equation. The age is the time since an individual entered the protection phase. The model is then reduced by integration on the characteristics to a differential‐difference system with delay. The discrete delay represents the limited duration of the protection phase. After establishing the basic properties of the model, we show that the disease‐free equilibrium (DFE) is globally asymptotically stable when the basic reproduction number is less than one and is unstable when this number is greater than one. Furthermore, we show that even if there is no mortality during the protection phase and the basic reproduction number is greater than one, the endemic equilibrium is globally asymptotically stable. The proofs of the global asymptotic stability of both equilibria are based on carefully constructed Lyapunov functions. To complete this study on the global dynamics, we discuss some results on weak and strong uniform persistence of the disease. Finally, numerical simulations are performed to illustrate and complete our main results.
Eddy currents analysis methods for an MRI longitudinal gradient coil
Authors: Alsharafi Sadeq S , Badawi Ahmed M , El‐Sharkawy AbdEl‐Monem M
Published: July 2023

Purpose

The rapid switching of the gradient fields induces eddy currents in neighboring metallic structures, causing undesirable effects. Numerical computations are thus required to understand eddy‐currents effects for designing/implementing mitigation (involving passive shielding) and compensating techniques (using pre‐emphasis). Previously, the network‐analysis (NA) method was introduced to compute z‐gradient eddy currents, although limited to a circularly symmetric and unconnected coil. Multi‐layer integral method (MIM) method was recently introduced, modifying the circuit equation involving stream functions. We tailor MIM (TMIM) for a more general eddy‐currents analysis in thin structures. Z‐gradient eddy currents are analyzed and then compared using three methods (NA, TMIM, and Ansys). The analysis helps to evaluate the efficiency of passive shielding and to compensate eddy currents.

Methods

NA and TMIM computational frameworks for harmonic and transient eddy‐currents analysis were implemented and cross‐validated against Ansys Maxwell. A pre‐emphasis pulse was modeled for compensating eddy currents.

Results

Eddy‐currents analysis of an unconnected z‐gradient coil in both the passive shield and cryostat were computed, and results were comparable to the least computationally efficient Ansys simulations. Although NA computations are fast, TMIM is implemented with reasonable efficiency and applied to circularly unsymmetric geometries. TMIM computations were further validated against Ansys using a connected z‐gradient. Our computations allowed the effective evaluation of the performance of three various passive‐shielding configurations, non‐capped, capped, and slitted (for the first time), and an effective pre‐emphasis compensation model was computed.

Conclusion

Three eddy‐currents analysis methods were studied and compared. Computationally efficient TMIM allows both harmonic and transient eddy‐currents analysis involving different/complex gradient configurations/situations as well as involved shielding structures. Eddy‐currents pre‐emphasis compensation was demonstrated.
Corroborating evidence for aberrant expression of histone deacetylase 8 in endometriosis
Authors: Zheng Hanxi , Liu Xishi , Guo Sun‐Wei
Published: July 2023

Purpose

The aim of this study was to evaluate the dynamic change in staining of Class I HDACs and Hdac6 in lesions harvested serially from different time points in mice with induced endometriosis. In addition, the effect of Hdac8 activation as well as Hdac8 and Hdac6 inhibition on lesional progression and fibrogenesis was evaluated.

Methods

Immunohistochemistry analysis of Class I HDACs and Hdac6 in serially harvested lesion samples in mouse. Hdac8 activation, as well as Hdac6/8 inhibition, was evaluated in mice with induced endometriosis.

Results

We found a progressive increase in lesional staining of Hdac1, Hdac8, and Hdac6 and gradual decrease in Hdac2 staining and consistently reduced staining of Hdac3 during the course of lesional progression. The stromal Hdac8 staining correlated most prominently with all markers of lesional fibrosis. Hdac8 activation significantly accelerated the progression and fibrogenesis of endometriotic lesions. In contrast, specific inhibition of Hdac8 or Hdac6, especially of Hdac8, significantly hindered lesional progression and fibrogenesis.

Conclusions

Hdac8 is progressively and aberrantly overexpressed as endometriotic lesions progress. This, along with the documented HDAC1 upregulation in endometriosis and the overwhelming evidence for the therapeutic potentials of HDACIs, calls for further and in‐depth investigation of epigenetic aberrations of endometriosis in general and of HDACs in particular.
The nephrotoxin ochratoxin a impairs resilience of energy homeostasis of human proximal tubule cells
Authors: Schwerdt Gerald , Kopf Michael , Gekle Michael
Published: July 2023

Despite a long history of research, the mode of action of the mycotoxin ochratoxin A (OTA) is still not clear. Based on our observation that OTA-exposed cells consume more glucose and produce more lactate than control cells, with this study, we want to suggest another possible mode of action of OTA, involving cellular metabolism and mitochondria. We exposed human proximal tubule cells (HK2 cells) to OTA and studied its influence on mitochondrial performance as well as on the expression of energy homeostasis-involved routing proteins (AMPK and TXNIP) and on glucose transporting and metabolizing proteins. OTA reduced the capacity of mitochondria to increase their oxygen consumption rate forcing the cells to switch to the ineffective anaerobic glycolysis which demands higher glucose availability. The higher glucose demand is met by augmented cellular glycogen degradation and increased glucose uptake capabilities by increasing glucose transporter expression. We conclude that OTA exposure leads to impaired mitochondria, which forces the cells to alter their metabolism in order to ensure energy supply. We suggest to consider a possible effect of OTA on metabolism and mitochondria and to have a closer look on OTA-induced changes in the metabolome as possible additional players in OTA toxicity.
Teachers’ Awareness and Sensitivity to a Bullying Incident: A Qualitative Study
Authors: Paljakka Antonia
Published: July 2023

This qualitative study explores how teachers assess a bullying scenario and what considerations guide their assessment. Thirty-eight secondary school teachers from across Austria participated in an online survey with open-ended questions based on two vignette: one depicting an incident of verbal and social bullying and the other a non-bullying incident of physical violence. Data were analyzed using qualitative content analysis. Although participating teachers did not know that bullying was the study focus, they still showed sensitivity toward bullying, in terms of recognizing and labelling the incident. However, the teachers’ answers also showed that their assessment only partly coincides with those criteria that are central in the scientific discussion of bullying. While the aspects of doing (intentional) harm and imbalance of power were relevant to teachers’ assessments, the criterion of repetition was not. The results further suggest that participants’ awareness and interventions are closely related to situational aspects, personal and professional experiences, beliefs, and attitudes and only to a small extent to knowledge or training. Implications for teachers’ education and research are discussed.
Safety Initiatives in Support of Safety Culture Development: Examples from Four Mining Organisations
Authors: Sundström Erik , Nygren Magnus
Published: July 2023

Having seen significant improvements to accident rates in the last 40 years, companies in the Swedish mining industry now show a greater focus on the development of safety cultures throughout their organisations and workplaces. However, there is a lack of research examining the different safety initiatives and strategies practiced in the industry today. This study explores the potential influence and consequences such initiatives may have on the development of safety cultures in the Swedish mining industry. Twelve interviews with experts on safety initiatives from four different Swedish mining organisations were conducted and analysed in a process based on qualitative thematic analysis to identify notable connections to safety culture development. The results of these interviews highlight proclivities in the implementation and use of safety initiatives such as subjects of focus, methods and desired effects. This enables the interpretation of the conceptualisation and methods for the development of safety culture in these organisations based on their approaches to safety development. We believe the results of this study can serve as support for discussions on safety culture development in the Swedish mining industry, and be of interest for international mining industries, in addition to approaches to research in this field. However, we also believe it is important to emphasise the opportunities to approach safety culture in mining from different perspectives than those common today.
Ever Not Quite
Authors: Araujo Saulo de Freitas , Osbeck Lisa M.
Published: July 2023

William James made many references to pluralism throughout his career. Interestingly, many contemporary psychologists also discuss pluralism and indeed call for pluralism as a corrective to the discipline's philosophical and methodological foundations. Yet, pluralism and the purposes to which it is applied are understood in a variety of ways, and the relation of contemporary pluralism to the pluralism(s) of William James is uncertain. This book offers conceptual clarification in both contexts, first distinguishing diverse senses of pluralism in psychology and then systematically examining different forms of pluralism across the writings of James. A comparison of meanings and analysis of implications follows, aimed at illuminating what is at stake in ongoing calls for pluralism in psychology.
Flow past a sphere translating along the axis of a rotating fluid: revisiting numerically Maxworthy's experiments
Authors: Aurégan Tristan , Bonometti Thomas , Magnaudet Jacques
Published: July 2023

We compute the flow induced by the steady translation of a rigid sphere along the axis of a large cylindrical container filled with a low-viscosity fluid set in rigid-body rotation, the sphere being constrained to spin at the same rate as the undisturbed fluid. The parameter range covered by the simulations is similar to that explored experimentally by Maxworthy (J. Fluid Mech., vol. 40, 1970, pp. 453–479). We describe the salient features of the flow, especially the internal characteristics of the Taylor columns that form ahead of and behind the body and the inertial wave pattern, and determine the drag and torque acting on the sphere. Torque variations are found to obey two markedly different laws under rapid- and slow-rotation conditions. The corresponding scaling laws are predicted by examining the dominant balances governing the axial vorticity distribution in the body vicinity. Results for the drag agree well with the semi-empirical law proposed for inertialess regimes by Tanzosh & Stone (J. Fluid Mech., vol. 275, 1994, pp. 225–256). This law is found to apply even in regimes where inertial effects are large, provided that rotation effects are also large enough. Influence of axial confinement is shown to increase dramatically the drag in rapidly rotating configurations, and the container length has to be approximately a thousand times larger than the sphere for this influence to become negligibly small. The reported simulations establish that this confinement effect is at the origin of the long-standing discrepancy existing between Maxworthy's results and theoretical predictions.

In community assembly processes, interspecific interactions play an important role in shaping community diversity, especially at the local scale. Changes in species richness or abundance can modify local infectious disease dynamics, either reducing or increasing the risk of transmission within the community. This study evaluates the effects of bird community on avian haemosporidians infections in a Neotropical region. Bird samples were collected from areas surrounding three dams, and molecular analysis were performed to identify blood-parasitic haemosporidia infecting the birds. Generalized linear models were used to analyze the relationships between the bird community and the prevalence, number of infections, and richness of avian haemosporidian lineages. Non-significant effects of bird community dominance and richness on the prevalence of avian parasites and the number of infections of Haemoproteus were found. However, there was evidence of an amplification effect. Host dominance was associated with the total number of infections, the number Plasmodium infections and the expected richness of Plasmodium lineages, while the expected richness of Haemoproteus lineages was associated with the richness of bird species. These findings highlight the role of host community dominance and richness in the dynamics of parasite infections, potentially influenced by the availability of competent hosts. This study contributes significantly to our understanding of blood parasite diversity in tropical birds within a relatively understudied region of South America.

Using protein structure to predict function, interactions, and evolutionary history is still an open challenge, with existing approaches relying extensively on protein homology and families. Here, we present Machaon, a data-driven method combining orientation invariant metrics on phi-psi angles, inter-residue contacts and surface complexity. It can be readily applied on whole structures or segments—such as domains and binding sites. Machaon was applied on SARS-CoV-2 Spike monomers of native, Delta and Omicron variants and identified correlations with a wide range of viral proteins from close to distant taxonomy ranks, as well as host proteins, such as ACE2 receptor. Machaon’s meta-analysis of the results highlights structural, chemical and transcriptional similarities between the Spike monomer and human proteins, indicating a multi-level viral mimicry. This extended analysis also revealed relationships of the Spike protein with biological processes such as ubiquitination and angiogenesis and highlighted different patterns in virus attachment among the studied variants.

Employment and Work Task Characteristics of 111 Swedish School-Based Speech-Language Pathologists
Authors: Sandgren Olof , Samuelsson Christina , Fredriksson Emma , Järnvall Ebba , Ekström Anna
Published: July 2023

Purpose:

Speech-language pathologists (SLPs) are a new but rapidly growing addition to the Swedish school work force. This study sought to inventory the employment and work task characteristics of school-based SLPs to assess equitable access to SLP services.

Method:

We collected questionnaires from 111 SLPs currently practicing in Swedish schools. The respondents were asked for details regarding their employment.

Results:

Roughly equal proportions of respondents reported to work with intervention and consultation to teaching staff. Almost all reported that the preservice training provided insufficient preparation for school-based practices. The work assignments of school-based SLPs were more similar than 10 years ago, likely a consequence of agreements between the parties caring for students with language disorder, and the vast majority of SLPs now being employed within student health teams. However, differences in workload and assigned tasks affect the nature of the work performed, to the point that current best practice cannot always be upheld.

Conclusions:

The results indicate that the services provided by Swedish school-based SLPs can be expected to vary because of qualitative and quantitative differences in employment and work task characteristics. The results are discussed in light of reviews of language interventions for children and young people.
Machines that feel: behavioral determinants of attitude towards affect recognition technology—upgrading technology acceptance theory with the mindsponge model

Published: July 2023

The rise of emotional AI signals a new era in human-machine relations where intelligent machines not onlyfeelbut alsofeedon human emotions as statistical fodder with the goal of reshaping our behavior. Unlike many smart technologies, emotion-recognition systems sense, monitor, harvest and analyze data extracted from a person’s non-conscious or psycho-physical state, often without their knowledge or consent. As a far more invasive manner of surveillance capitalism, the technological adoption of emotional AI is problematized by a myriad of legal, ethical, cultural, and scientific issues. To better understand the behavioral factors determining an individual’s attitude towards this emerging technology, we first identify five major tensions that may impinge on adoption. Second, we extend the Technological Acceptance Model (TAM) (Davis, 1989) model with insights from the mindsponge model of information filtering (Vuong and Napier, 2015) along with quantitative affordances offered by the Bayesian computational approach. Our analysis was conducted based on a multi-national dataset surveying perceptions of 1015 young adults (age 18–27) regarding emotional AI applications and their socio-cultural characteristics such as income, region, religiosity, and home country politics. These characteristics are fed into our Bayesian multi-level models as varying intercepts so that we can systematically measure and compare the effects of various behavioral determinants on the attitudes of respondents towards non-conscious data harvesting by government and private sector actors. Critically, this study finds respondents who feel more familiar with, and perceive more utilities in AI technologies, as well as rate themselves as more restrained from heated arguments on social media, feel less threatened by the practice of non-conscious data harvesting by both government and private sector actors. Our findings offer a fertile platform for further exploration of the intersection between psychology, culture, and emotion-recognition technologies as well as important insights for policymakers wishing to ensure design and regulation of the technology serve the best interests of society.
Urban Sprawl Symptoms in Makassar City
Authors: Amri Erwin , Manaf Murshal
Published: July 2023

Urban sprawl symptoms are characterized by the phenomenon of the expansion of urban functional areas into urban fringe areas. The residential area of Bumi Tamalanrea Permai Makassar showed the symptoms, where the dynamics of densification and dualistic residential areas and the region’s growth have exceeded the supporting capacity and basic availability infrastructure in the area. This article was intended to explore the processes, activities, and analysis of urban sprawl symptoms in urban fringe using a mixed quantitative and qualitative/mixed methods approach. The research results show that there has been densification, dualistic settlements, gated areas beyond urban functional boundaries, and changes in the pattern of the transformation of physical and spatial functions toward the urban fringe in such a way that they form urban sprawl.

Published: July 2023

This research aims to determine the ability of Pluchea indica Less methanol extract as an inhibitor in the low carbon steel corrosion in 1 M hydrochloric acid media. HCl solution was reacted with P. indica Less leaves extract to decelerate the process of oxidation of iron (Fe) with concentration variations of 0 ppm, 500 ppm, 1000 ppm, 1500 ppm, and 2000 ppm immersion time of 2, 4, and 6 days. The corrosion level was determined by the loss of weight and the method of potentiodynamic polarization. Low carbon steel delineation was analyzed using the instrument of Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS). The loss of weight and the method of potentiodynamic polarization indicated the lowest level of corrosion at six days of immersion with the concentration of extract of 2000 ppm, each of 2.5195109 mmpy with 97 % efficiency 2.18225455 mmpy with the efficiency of 98 %. The superficies of carbon steel immersed in HCl 1 M solution without inhibitor contained more holes and cracks than the superficies of carbon steel immersed in HCl 1 M solution in the presence of P. indica Less leaves extract. The results showed that P. indica Less leaves extract can inhibit corrosion of low carbon steel in acid media HCl 1 M. Greater extract concentration and longer immersion time result in a lower level of corrosion and greater efficiency of inhibition.
