TINJAUAN SOSIOLOGIS TREND BERSEPEDA DI TENGAH PANDEMI VIRUS CORONA
Authors: Darsini Sri
Published: December 2022

Di Indonesia pandemi di manfaatkan dengan bersepeda dengan tujuan awal agar sehat dan imunitas meningkat. Akan tetapi lambat laun tujuan ini tidak sesuai lagi. Bersepeda menjadi suatu trend dari berbagai kalangan dengan berbagai motif yang melatarbelakanginya. Penelitian ini adalah deskriptif kualitatif yang bertujuan untuk menjelaskan tinjauan sosiologis terhadap Trend Bersepeda Di Tengah Pandemi Virus Corona. Teknik pengumpulan data yang terdiri dari observasi, wawancara, dokumentasi kemudian dianalisis dengan perspektif teori Jean Paul Baudrillard tentang Nilai Tanda yang mana untuk tempat penelitian di fokuskan di Desa Karangtengah, Weru, Sukoharjo.

Hasil penelitian menunjukkan bahwa tujuan awal dari olahraga bersepeda di tengah pandemi virus corona adalah masyarakat menginginkan agar badannya sehat jauh dari paparan virus corona. Setelah di kaji secara sosiologis dengan menggunakan perspektif teori Jean Paul Baudrillard hasil penelitian menunjukkan bahwa bersepeda bukan lagi bertujuan agar badan sehat akan tetapi bersepeda menjadi trend di kalangan masyarakat untuk menunjukkan status sosialnya. Masyarakat dari kalangan atas akan membeli sepeda dengan harga puluhan hingga ratusan juta. Sedangkan masyarakat menengah kebawah akan membeli sepeda sesuai dengan keuangannya. Hal ini yang peneliti dapatkan selama di lapangan bahwa dari sepeda yang dimiliki masing-masing pesepeda menunjukkan seberapa besar mereka memiliki uang. Dari pernyataan tersebut dapat diketahui bahwa tujuan seseorang olahraga bersepeda bukan lagi karena menginginkan badannya sehat, akan tetapi lebih kepada agar menunjukkan status sosial ekonomi mereka.

Abstract
This research studied the onomatopoeic verb in Emma Donoghue’s novel entitled ROOM. The aims of this research were to find the translation strategies applied in translating onomatopoeic verbs that are used by the translator in the ROOM novel and to assess their quality in terms of accuracy and acceptability. This research applied descriptive qualitative method where the data was analyzed through Baker’s theory and those called raters who have competencies in assessing translation quality. The approaches used to collect and analyze the data of onomatopoeic verbs were content analysis and Focus Group Discussion. As a result, the researchers found that there are five translation strategies that are applied in translating onomatopoeic verbs. The researchers concluded that the majority of the translation strategies used in the ROOM novel involve the use of non-onomatopoeic words with similar meaning and form. The translation quality of onomatopoeic verbs is rated as less accurate and less acceptable, because of various factors that may be read in depth in this article.

Keywords: ROOM novel, onomatopoeia, onomatopoeic verb, translation strategies, translation qualities.

Published: December 2022

O Empreendedorismo Internacional (EI) e as Capacidades Dinâmicas (CDs) vêm ganhando destaque, principalmente, em empresas de base tecnológica. A busca por esse alcance leva as organizações a assumirem riscos e utilizarem-se de posições proativas e empreendedoras. Para chegarem ao objetivo desejado, as organizações adaptam processos, rotinas e ferramentas. Esse elo entre as capacidades dinâmicas e o Empreendedorismo Internacional se apresentaram imprescindíveis para alcançar o sucesso da internacionalização. Este artigo busca analisar como as capacidades dinâmicas influenciam o empreendedorismo internacional de empresas do Porto Digital. Para viabilizar a investigação, foi realizado o estudo de múltiplos casos com empresas aportadas nesse parque tecnológico. Os dados foram coletados por meio de entrevistas com gestores estratégicos, os quais detinham informações acerca da internacionalização dos empreendimentos, bem como dados secundários que foram obtidos a partir de matérias de jornais e revistas via acesso por assinatura. Revelaram-se dois elos entre as capacidades dinâmicas e as dimensões do EI, a saber: identificação e exploração de oportunidades e a capacidade de estabelecer relacionamentos, propensão à adaptação e a capacidade de aprendizagem. Considerado um campo ainda recente, na literatura existem poucos estudos em países de economia emergente. Tanto as limitações quanto os aprendizados dos gestores estratégicos para internacionalização contribuem para uma visão mais robusta sobre o processo de internacionalização e aplicação das capacidades dinâmicas para a sobrevivência e ganho de vantagem competitiva nas empresas. A investigação e a compreensão do tema em empresas sediadas em um dos maiores parques tecnológicos da América Latina revela a influência entre as CDs e as dimensões do EI que ocorrem de forma tênue e imperativa para o processo de internacionalização.

Authors: Savvova O. , Tymofieiev V. , Voronov H. , Fesenko O.
Published: December 2022

The necessity of creating innovative protective structures for armoring machinery and equipment is analyzed. A comparative analysis of high-strength materials used for local and individual body armor has been carried out.  The relevance of the development of domestic universal armored materials that combine high strength properties and radio transparency based on lightweight technological magnesium aluminosilicate glass-ceramic materials with high performance properties at the level of world analogues has been determined.  Were formulated the purpose and tasks of the work, which consist in: analysis of the current state of development of glass-ceramic materials for armor protection; development of magnesium-aluminosilicate glass-ceramic materials with high armor resistance, impact resistance and radio transparency; investigation of the operational properties of the developed glass-ceramic materials and their armor resistance; assessment of the competitiveness of the developed glass-ceramic materials. A set of requirements for a glass matrix for obtaining protective glass-ceramic materials has been formulated. Compositions and technological parameters for the production of glass-ceramic materials under the conditions of two-stage low-temperature heat treatment have been developed. The study of the electrical properties of experimental glass-ceramic materials made it possible to establish the possibility of effective functioning of on-board wireless communication systems when using the developed materials as elements of armor protection. It was found that the developed glass-ceramic materials are characterized by high operational properties (KCU = 5.8 kJ/m2; HV = 10.4 GPa; K1C = 8.5 MPa∙m1/2) and armor resistance STANAG 4569 (level 2). The competitiveness of the developed glass-ceramic materials based on mullite is analyzed. It has been established that a significant increase in fracture toughness and a decrease in the density of the developed material when comparing properties with a similar armor element (corundum-based plate) will significantly reduce the weight of the armor elements by ≈1.4 times and its cost by five times, while maintaining its protective properties.

Published: December 2022

Story poetry as a branch of the big tree of poetry and literature in Abbasid era, is one of the important tools for discovering historical facts. This study showed that ‘Alī ibn al-Jahm can be considered one of the pioneers of this literary art in the Abbasid era. He paved the way for poets to depict history in this format and create novel works in this era and immortalize those historical events. By analyzing each element of the story in ‘Alī ibn al-Jahm’s chapter “Creation of Adam”, this study has proved that this work is a story poem and also tries to determine the poet’s goals from the order of this work for the audience. The results of this study show that the aim of ‘Alī ibn al-Jahm in this poem is to teach the teachings of Islam to the audience and people of his time in addition to retelling the events and history of the prophets. Considering that ‘Alī ibn al-Jahm was a court poet and praiser of the caliphs of Banī ‘Abbās, probably the aim of the poet is also to teach a lesson from the caliphs and also the behavior of the prophets and the ancients.

Photogrammetry and GIS to investigate modern landscape change in an early Roman colonial territory in Molise (Italy)
Authors: Peters Manuel J. H. , Stek Tesse D.
Published: December 2022

Legacy data in the form of historical aerial imagery can be used to investigate geomorphological change over time. This data can be used to improve research about the preservation and visibility of the archaeological record, and it can also aid heritage management. This paper presents a composite Image-Based Modelling workflow to generate 3D models, historical orthophotos, and historical digital elevation models from images from the 1970s. This was done to improve the interpretation of survey data from the early Roman colony of Aesernia. The main challenge was the lack of high-resolution recent digital elevation models and ground control points, and a general lack of metadata. Therefore, spatial data from various sources had to be combined. To assess the accuracy of the final 3D model, the RMSE was calculated. While the workflow appears effective, the low accuracy of the initial data limits the usefulness of the model for the study of geomorphological change. However, it can be implemented to aid sample area selection when preparing archaeological fieldwork. Additionally, when working with existing survey datasets, areas with a high bias risk resulting from post-depositional processes can be indicated.

The recent increase on the Internet of Things and Industry 4.0 fields has led the research topics to investigate on the innovative technologies that could support these emerging topics in different area of applications. In particular, the current trends are to close the gap between the physical and digital worlds, thus originating the so-called Cyber-Physical System (CPS). A relevant feature of the CPS is the digital twin, i.e., a digital replica of a process/product with which user can interact to operate on the real world. In this paper, the authors propose an innovative approach exploiting an Augmented Reality solution as Digital Twin for the measurement instrument to obtain a tight connection between the measurements as physical world and the Internet of Things as digital applications. In fact, by means of the adoption of the 3D scanning strategy, Augmented Reality software and with the development of a suitable connection between the instrument and the digital world, a Cyber-Physical System has been realized as an IoT platform that collect and control the real measurement instrument and makes its available in Augmented Reality. An application example involving a digital storage oscilloscope is finally presented to highlight the efficacy of the proposed approach.

Unveiling the True Micro-Structure in PdRu Immiscible Alloys and Its Application in Alkaline Hydrogen Evolution Reaction
Authors: Hu Zheng , Li Hui , Zhao Wenbo , Zhou Wei , Hu Shi
Published: December 2022

The structure information in a disordered atomic system could not be acquired from the daily X-ray diffractometers, but has to resort to the synchrotron sources. The pair distribution function from the synchrotron X-ray and neutron scattering reflects the local bond information regardless of the crystallinity, but the limited access to these high-energy light resources prevents them from wide use. Herein we developed a microstructure analysis framework to study the immiscible binary alloys, through the integration of local elemental segregation analysis, electron-based pair distribution function, the corresponding wavelet coherence spectrum, and ab-initio level simulation. All the information could be obtained from an in-house transmission electron microscope equipped with an energy dispersive spectroscope. A series of nanoparticles based on immiscible Pd-Ru alloys were chosen as the model catalysts for hydrogen evolution reaction and the structure-performance relationship was established based on the electrochemical tests and the structure information from the analysis toolkit we developed.
Viscous fingering in volatile fluid towards spontaneous evolution of well-ordered 3D patterns
Authors: Rakshe Makrand , Gandhi Prasanna
Published: December 2022

Mimicking nature using artificial technologies has always been a quest/fascination of scientists and researchers of all era. This paper characterizes viscous fingering instability-based, lithography-less, spontaneous, and scalable process for fabricating 3D patterns like a nature-inspired honeycomb structure with ultra-high aspect ratio walls. Rich experimental data on volatile fluids shaping in uniport and multiport lifted Hele-Shaw cells (ULHSC and MLHSC) obtained through extensive experiments is represented on a non-dimensional phase plot. The phase plot with five orders of magnitude variation of non-dimensional numbers on each axis demarcates the regions of several newly observed phenomena: ‘No retention’, ’Bridge breaking’, and ‘wall formation’ with ‘stable’ and ‘unstable’ evolution. A new non-dimensional ratio of the velocity of evaporating static interface vs. lifting velocity is proposed for the same. This work establishes a solid foundation with valuable insights for scalable manufacturing of devices useful for application in biomedical and other domains.
Enhancing the Adsorption Performance of Chitosan to Phenol Derivatives through Hydrophobic Modification: Kinetics, Equilibrium, and Mechanisms
Authors: li kebin , wang meiling , huo wenting , wei hong
Published: December 2022

Adsorption is effective methods to remove trace organic pollutants in water, and the development of cheap and efficient adsorption materials is essential to the real application of this technique. In this study, chitosan, a natural aminopolysaccharide, was grafted with palmityl chloride using an acylation procedure to improve its hydrophobicity and adsorption capacity to hydrophobic organic contaminants. A hydrophobically-modified chitosan (HMC2) was characterized using Fourier transform infrared spectroscopy (FTIR), and then was tested to adsorb phenolic pollutants from water. The batch adsorption experiments were employed to investigate the adsorption equilibrium and kinetics of 4-nonylphenol(4-NP), α-naphthol(Nap), 4-chlorophenol(4-CP) and phenol(Phe) on HMC2 and chitosan. The effect of temperature, salt concentration, and pH on adsorption was studied for the understanding of adsorption processes. Moreover, a linear free energy relationship approach and FTIR technique were used to identify the predominant adsorption mechanisms. The obtained results showed that the modified chitosan had higher adsorption capacity to 4-NP, Nap, 4-CP and Phe than the unmodified one. The adsorption kinetics of 4-NP, Nap and 4-CP on chitosan and HMC2 were found to be well fitted by the first-order kinetic model. The adsorption isotherms of 4-NP, Nap, 4-CP and Phe on HMC2 conformed to the linear or Freundlich models. The pH range from 5.6-8.5 appeared to have non-significant effect on the adsorption capacity of HMC2. However, the increasing salt concentration was found to favor the adsorption. The adsorption enthalpy changes (ΔH0) for 4-NP, Nap and CP on HMC2 varied from -3.82 to -0.44 kJ/mol, and the adsorption entropy changes (ΔS0) changed from 21.7 to 85.9 J/(mol·K). When the logarithms of the distribution constant (logKd) were correlated with the logarithms of the octanol-water partition coefficient (logKow), a good linear relationship was observed:logKd=1.451·logKow - 4.893 (r2=0.999). Thus, the hydrophobic interaction was proposed as a predominant mechanism for adsorption of nonionized 4-NP, Nap, 4-CP, and Phe on HMC2, which was further confirmed by the FTIR data. This study may provide guidance for tailoring high-performance chitosan to selectively remove organic pollutants in water.
GEODYNAMIC PROCESSES IN THE UPLIFT SLOPE

The flow for the uplift slope is considered in the viscous liquid model. The relevance of the study is justified by the need for experimental and theoretical analysis of the geodynamic processes occurring in the slopes of rises. The object of the study is the slopes of rises, formed by mantle thermochemical plumes which have not come to the surface. The objectives of the study are to present the velocity profile of the viscous flow of the uplift slope and to determine the friction coefficient for it; to find out the effect of the dynamic viscosity coefficient of the slope on the appearance of compressive and tensile stresses; on the basis of laboratory and theoretical simulations to find out the hydrodynamics of the flow when the liquid flows from a rectangular vessel and using the results of geodynamic simulations to determine the flow parameters in the area of the uplift slope fault formation. The flow occurring in a viscous liquid at a constant inclination angle of the free surface of the elevation slope is considered. In a highly viscous liquid at low flow velocities, the inertial terms in the equation of motion can be neglected. For this case, the solution of the equation of motion in a layer with an inclined free surface at a constant horizontal pressure gradient is obtained. The flow velocity profile in such a layer and the relation for the maximum flow velocity are obtained. The tangential stress on the sole of the layer is determined. The tangential stress does not depend on the viscosity, but depends on the layer thickness. With a constant viscosity of the layer, the elevation slope is under conditions of compressive stresses. Strain conditions for the uplift slope are possible when the viscosity of the layer decreases with distance from the main ridge. Discontinuities occur on the elevation slopes due to changes in viscosity along the slope and changes in the velocity. Under the influence of gravitational forces caused by the density difference at the rupture boundary, flow occurs and the resulting free volume is filled. The motion in a highly viscous liquid during the formation of a free vertical surface has been studied experimentally when liquid flows out of a transparent rectangular vessel. Photographs of the free surface were obtained. A linear dependence of the relative height of the free surface location on the relative horizontal coordinate is observed. Expressions are obtained for the average velocity and expiration time of a viscous liquid from a rectangular vessel. Estimates of the average velocity and outflow time for the specified slope parameters are presented

El desarrollo de competencias digitales en estudiantes de educación superior está fuertemente mediado por sus experiencias personales. Esta investigación tuvo como propósito analizar la frecuencia de usos académico, recreativo, social y económico de tecnologías digitales en estudiantes de pedagogía, en razón de cuatro variables: tipo de competencia digital, sexo, permanencia en el programa y aprobación de asignaturas. Un total de 615 estudiantes de pedagogía, pertenecientes a dos universidades chilenas, contestaron un cuestionario que mide cinco competencias digitales, en cada uno de los cuatro usos mencionados, obtenidas del DigComp. Análisis de varianza mostraron, en lo principal, una relación inversa entre la complejidad de las competencias y la frecuencia de su uso. Las mujeres reportaron un mayor uso académico y un menor uso recreativo que los hombres. Además, estudiantes con uno o dos años de permanencia en el programa reportan menores usos académicos, sociales y económicos. La relación inversa observada entre la complejidad de las competencias y la frecuencia de uso económico y recreativo fue más robusta entre quienes habían aprobado todas las asignaturas. Los resultados obtenidos contribuyen a una mejor comprensión de los vínculos entre los propósitos de uso, su frecuencia de empleo y el desarrollo de competencias digitales.

La pandemia ha evidenciado la capacidad de determinados proveedores de servicios tecnológicos, especialmente de plataformas digitales, para adaptarse y responder rápidamente a las supuestas necesidades del sistema educativo.

En este artículo identificamos algunas de las tensiones que la intensificación en la adopción de plataformas digitales educativas ha evidenciado en el ámbito escolar y familiar. A partir de un diseño metodológico mixto, que incluyó la realización de seis entrevistas en profundidad a directores/as de centros educativos y la aplicación de una encuesta a 2112 familias, se analizaron los posicionamientos de la comunidad escolar y de las familias sobre el uso de plataformas educativas digitales en centros educativos públicos de Cataluña.

Los resultados revelan conflictos vinculados a la “necesidad” de adaptarse a una realidad post-digital en la que adoptar posturas críticas -minoritarias- se percibe como una amenaza para el libre desarrollo de la práctica profesional y para el acceso a la educación en condiciones de igualdad. Al mismo tiempo, los resultados subrayan el papel del profesorado en la profundización de posturas críticas y reflexivas que posibiliten, también para el alumnado, el cuestionamiento de formas naturalizadas de trabajo e interacción.

Published: December 2022

Las hackatones cívicas suponen una nueva forma de dar respuesta a los principales retos socioeducativos. Desde una aproximación descriptiva-interpretativa, se realiza un despliegue metodológico mixto y evolutivo a lo largo de tres estudios de campo. El primero es una investigación-acción en la comunidad del barrio del Raval deBarcelona. El segundo supone la iteración del modelo con un rol no participante. El tercero es una inmersión internacional en el contexto hacker del MIT Media Lab para contrastar los aprendizajes realizados y abrir nuevas líneas de investigación. Los resultados indican el protagonismo inequívoco de los factores de proceso y empoderamiento personal y comunitario por encima del impacto derivado de las soluciones creadas. Por otra parte, se evidencia una relación significativa entre las predisposiciones competenciales creativas y colaborativas de los participantes y su eficacia a la hora de crear soluciones. También se muestra el potencial de la hackatón para enriquecer el capital social comunitario. Por último, se propone un marco de competencias que ayude a hacer tangibles los beneficios de la participación, promueva la evaluación del modelo e inspire nuevas investigaciones.
The Concept of Thought from the Perspective of Cultural Codes in Kazakh Fiction
Authors: Rumyantseva M. V.
Published: December 2022

The modern linguistics interprets the old philosophical problem of the relationship between reality, thinking, and language in a completely new way: the world should be considered as a whole and comprehended through linguistic, mythological, religious, and artistic worldviews at once. The abstract concepts of the mental world represent a certain linguistic culture. This article describes a set of cultural codes that represent the mental concept of thought as similes in the contemporary Kazakh fiction. This linguaculturological analysis covered metaphors and similes found by continuous sampling in the Kazakh fiction of the XX century. The similes were tested for regular metaphorization models. The mental concept of thought in similes was presented through natural, biomorphic, and artefact cultural codes. The natural cultural code was represented by such conceptual metaphors as thought is wind / sunlight / fire / water. The zoomorphic metaphors of thought is horse / bird / insect were numerous in the biomorphic cultural code. The metaphor of thought is metal verbalized the artefact cultural code. In the linguistic consciousness of the Kazakhs, the concept of thought was verbalized as a divine gift or a living entity that has enough energy to take different material forms and move around all three worlds.
Controlled Future as a Factor of Human Behavior Intentionality
Authors: Repin M. V. , Dolganov D. N.
Published: December 2022

This theoretical and empirical study verifies the hypothesis that the desire to control one’s own future is a significant behavioral factor. A controlled future is a phenomenon at the intersection of internality and emotional response. The relationship between the level of internality and emotional response was analyzed at two levels. The first level featured stable personality traits. They were identified using standard personality questionnaires, namely the Standard Personality Traits Questionnaire modified by E. G. Ksenofontov and C. Izard’s Differential Emotions Scale adapted by A. V. Leonov and M. S. Kapitsa. The second level featured situational personal traits manifested in particular situations as a general state of emotional comfort or discomfort. The authors developed a questionnaire that included six types of situations, each of which had three response options. The first option presupposed a passive (external) position, i.e., waiting for help from others. The second option described an active (internal) position. The third option was intermediate (50/50). Each behavioral option required an assessment of emotional comfort. At the level of subjective-personal traits, the general level of personal internality determined the readiness for action and overcoming difficulties, often associated with negative emotional experiences. A lower readiness for action and transformation triggered stronger negative emotions. The level of situational behavior demonstrated a similar trend: a lower control over the situation was associated with a greater emotional discomfort. However, the relationship between control and emotional comfort was not linear. The level of emotional discomfort increased following the rise in the control level.
Pharmacological Treatment of Alcohol use Disorder in Patients with
Psychotic Disorders: A Systematic Review

Published: December 2022

Background:

Patients with psychotic disorders (PD) often have comorbid alcohol use disorder
(AUD), which is typically treated pharmacologically. Up till now, no systematic review has examined
the effectiveness and safety of AUD treatment in PD patients.

Objectives:

This study aimed to systematically review the literature on (1) the effects of pharmacological
treatments for AUD on drinking outcomes, (2) the side effects of the drugs, and (3) the effects of
polypharmacy in patients with comorbid AUD and PD.

Methods:

Bibliographic searches were conducted in MEDLINE, Embase, Cochrane Central Register
of Controlled Trials, and PsycINFO. At least two reviewers extracted the data, assessed the risk of bias,
and performed the qualitative synthesis of the collected evidence.

Results:

Twelve eligible studies were identified, half being randomized controlled trials (RCTs).
Three studies examined disulfiram, nine naltrexone, two acamprosate, and one nalmefene by comparing
the effects of treatment to placebo, baseline, or pharmacological agents. Disulfiram and naltrexone
were shown to reduce alcohol intake. Regarding acamprosate, the findings were mixed. Nalmefene
decreased alcohol intake. All pharmacological agents appeared safe to use as AUD monotherapy, but
cardiac events were reported when combining naltrexone and disulfiram. Nine studies had a high risk
of bias, and three had some other concerns.

Conclusion:

The studies provide tentative support for the use of naltrexone and disulfiram in this population,
although combinations of pharmacological AUD treatments and other polypharmacy remain
unexplored. The studies had high adherence rates that are hardly replicable in real-world settings.
Thus, the findings should be confirmed in larger high quality efficacy and effectiveness RCTs with
longer follow-ups.
How to Collect and Interpret Medical Pictures Captured in Highly
Challenging Environments that Range from Nanoscale to Hyperspectral
Imaging

Digital well-being records are multimodal and high-dimensional (HD). Better theradiagnostics stem from new computationally thorough and edgy technologies, i.e., hyperspectral (HSI) imaging,
super-resolution, and nanoimaging, but advance mess data portrayal and retrieval. A patient's state
involves multiple signals, medical imaging (MI) modalities, clinical variables, dialogs between clinicians and patients, metadata, genome sequencing, and signals from wearables. Patients' high volume,
personalized data amassed over time have advanced artificial intelligence (AI) models for higherprecision inferences, prognosis, and tracking. AI promises are undeniable, but with slow spreading and
adoption, given partly unstable AI model performance after real-world use. The HD data is a ratelimiting factor for AI algorithms generalizing real-world scenarios. This paper studies many health
data challenges to robust AI models' growth, aka the dimensionality curse (DC). This paper overviews
DC in the MIs' context, tackles the negative out-of-sample influence and stresses important worries for
algorithm designers. It is tricky to choose an AI platform and analyze hardships. Automating complex
tasks requires more examination. Not all MI problems need automation via DL. AI developers spend
most time refining algorithms, and quality data are crucial. Noisy and incomplete data limits AI, requiring time to handle control, integration, and analyses. AI demands data mixing skills absent in regular systems, requiring hardware/software speed and flexible storage. A partner or service can fulfill
anomaly detection, predictive analysis, and ensemble modeling.
Does the Provision of Assistive Technology Increase Disability Employment?
Authors: Rahmatika Rizka Astari , Pratiwi Chairani Putri , Basuki Carola
Published: December 2022

This paper examines various literature regarding the relationship between the provision of assistive technology (AT) and workplace integration for people with disabilities (PwD). A systematic review was conducted to map existing literature using the PRISMA framework in the last ten years. This study reveals that AT has an enormous significance in the employment of PwD. However, the provision of AT as workplace accommodations is not always uncomplicated as three aspects mainly impact it: employers’ perspective, accessibility of AT, and the availability of support from vocational and rehabilitation services. It is suggested that the provision of AT as workplace accommodations to increase disability employment should be supported collectively by society, with employers and the government as critical players. This study contributes to the perspectives of managers and the government by highlighting the roles they could carry out to create a more accessible provision of AT and an inclusive work environment.
