Authors: Weber Sigrid , Stoop Nik , van der Windt Peter Cornelis , Zhai Haoyu
Published: August 2024

Since the early 2010s, social scientists have conducted (survey-) experimental studies that explore what factors drive public attitudes towards migrants to understand who provokes backlash and who is welcomed. We conduct a systematic meta-analysis building on 83 studies that experimentally vary migrant characteristics to assess attitudes towards migrants. The study has several findings: a) sociotropic concerns play a key role: individuals are more welcoming towards migrants that contribute to the economy through their professional occupation, education or language skills; this evidence is particularly strong in developed countries compared to developing countries, b) thereis no evidence hosts evaluate migrants through the lens of egocentric economic concerns, c) cultural concerns are important; in particular a persistent anti-Muslim bias; d) humanitarian concerns also shape attitudes toward migrants; particularly towards those that are forcefully displaced in contrast to economic migrants.

Dualism of Subsidiaries in Indonesia: Between Juridical Independence and Economic Dependence of Subsidiaries in a Group of Companies
Authors: Nurdi Annurdi , Santoso Budi , Widhiyanti Hanif Nur , Dewantara Reka
Published: August 2024

In the limited liability company law currently in force in Indonesia, holding company and subsidiaries in the form of limited liability companies are seen as independent and separate legal entities, where each company has the right to independently carry out legal actions in accordance with the company’s interests. This differs from the concept of “group of companies” which consists of a collection of legally independent companies, where the subsidiaries are controlled by the holding company. This kind of concept raises fundamental questions considering that there is a contradiction between the principle of independence possessed by the company as an independent legal entity on one hand, and the reality of control by the holding company over its subsidiaries as a unitary economic entity. To answer this kind of problem, our paper offers a systematic explanation based on a normative and case approach to the company’s legal regime in Indonesia. This paper argues that the contradiction between the principle of independence and the reality of control by a parent company over its subsidiaries as an economic unit has the potential to prevent subsidiaries from moving independently based on their own business interests. The amount of control authority that the holding company has over its subsidiaries – as this paper will show – must be exercised by taking into account several things, including: the control does not conflict with legal regulations, does not cause losses to the subsidiaries, and does not harm the interests of the third parties as the limitation of control by the holding company.

The emergence of various fintech-based companies in the increasingly
widespread field of online lending and borrowing has brought several new
legal problems, namely the large number of personal data belonging to user
customers appearing on various sites or illegal online loan applications, so
that collection actions are carried out in an intimidating manner. Issues
taken regarding the form of legal protection for customers' personal data in
online loans, what forms of responsibility of online loan service providers
in the event of leakage and misuse of personal data against customers, and
future arrangements regarding the protection of personal data for customers
entering into online loan agreements. This research uses a normative
juridical research type using a statutory approach, a comparative approach,
and a conceptual approach. The form of legal protection is in accordance
with M. Isnaeni's view, namely through internal protection where protection
is realized through agreement clauses in accordance with Article 26 POJK
77/2016, and external protection emphasizes the protection provided by the
government through the ratification of the UUPDP. The responsibilities of
online loan providers have been regulate in Article 37 POJK 77/2016, for
errors or omissions that are the responsibility of the organizer, forms of
accountability in the form of compensation, compensation, and criminal
provisions. As well as future arrangements regarding the protection of
personal data, the existence of the UUPDP has not been able to reach public
protection because there are no implementing regulations that further
regulate technical implementing regulations regarding personal data
protection practices.
Peraturan di Tingkat Desa Legal?
Authors: Antari Putu Eva Ditayani , Utama I Made Arya
Published: August 2024

Villages are stated to be the smallest government structure in
Indonesia. A village is an area that has certain boundaries, as a legal
community unit that has the right to regulate and manage the affairs of
local communities based on their origins. Apart from that, the village
government also has the authority to determine legislative products
mentioned in village regulations. However, this form of legal regulation is
not included in the hierarchy of legal regulations in Indonesia, and in
practice it is rarely known by the public. Therefore, this research will
focus on identifying the legality of the position of regulations in villages
as part of the national legal and regulatory framework. The research method
used is a normative legal research method which discusses the position and
legality of regulations in the village based on applicable laws and
regulations as primary legal material. Apart from that, the discussion is
also complemented by secondary legal materials in the form of books and
articles published in journals based on theories, concepts, as well as legal
principles and adages. The research results show that the village government
is the smallest unit in the government system in Indonesia. The village
government, like other governments in the region, has the authority to
regulate and manage its government affairs autonomously based on the
division of affairs and rights according to the origins of the village.
Regarding this authority, the village government has the authority to form
village regulations and village head regulations. The status and legitimacy
of village regulations and village head regulations are recognized as
statutory regulations and have binding legal force as long as they are
formed based on higher statutory regulations or based on their authority
over the village's original rights.
Guardians of Privacy: Unraveling the Tapestry of Personal Data Protection
in Indonesia and France
Authors: Ariani Merizqa , Amboro FL. Yudhi Priyo , Nurlaily Nurlaily
Published: August 2024

The rapid advancement of technology has facilitated easier access to
information but has concurrently heightened the risks associated with the
security of personal data. This has raised concerns about individual
privacy, prompting the enactment of regulations for the protection of
personal data. Legal enforcement becomes crucial to ensure proper treatment
of personal data. Indonesia responded to the increasing cases of data
breaches by enacting the Personal Data Protection Act in 2022. However,
incidents of data leaks persist. France boasts a well-established data
protection law, notably the General Data Protection Regulation (GDPR), which
provides comprehensive guidelines for the management of personal data. There
are similarities and differences in the approaches of the two countries.
Both emphasize principles such as fairness, transparency, and
responsibility. However, France highlights openness and integrity, while
Indonesia places a greater focus on fairness and responsibility. Individual
rights take center stage in both regulatory frameworks, with an emphasis on
access, correction, and deletion of data. France introduces the rights to
protest and data portability to afford individuals greater control over
their personal data. Sanctions and legal enforcement are also crucial in
safeguarding personal data. Both countries impose sanctions, though there
are variations in implementation and enforcement. This research aims to
provide a better understanding of the differences and similarities in the
frameworks for personal data protection between Indonesia and France, with
the goal of strengthening data protection and enhancing public awareness.

Published: August 2024

Foreign Direct Investment (FDI) is one of the forms of international
investment that has significantly contributed to the prosperity of the host
country. However, with the growth of the economy, investment disputes have
been on the rise, involving both investors and the host government. While
Undang-Undang Nomor 25 Tahun 2007 provides sufficient legal safeguards to
address potential conflicts between investors and the government, host
countries often find it necessary to enter into specific agreements.
Undang-undang Nomor 5 Tahun 1968, which ratified the ICSID (International
Centre for Settlement of Investment Disputes) Convention, as a means to
protect foreign investors from conflicts with the Indonesian government.
This convention serves as a mechanism for dispute resolution and as an
international policy instrument to promote economic development. The
objective of this research is to elucidate the role and benefits of ICSID
arbitration in resolving investment disputes in developing countries and to
explain the mechanisms and procedures applied in resolving such disputes.
This paper is the result of normative legal research, which examines legal
rules relevant to the subject matter. ICSID aims to balance the interests of
host states and foreign investors, offering an efficient mechanism for
settling legal disputes in the field of foreign direct investment. The ICSID
agreement essentially establishes the authority of ICSID to resolve disputes
based on the written agreements of the parties involved.

Published: August 2024

Drugs are chemicals that are produced to reduce pain and prevent the risk of various diseases. In the manufacture of drugs, several stages of the process are needed which are quite long and require calculations from each process to produce products that meet the requirements and minimize errors during the process that can cause company losses. The research was carried out by direct observation during the process as well as collecting data on the mass of materials before and after the process, as well as critical parameters listed from the PPI (Main Processing Procedure) book for 1 batch of drug manufacture which takes more than 24 hours to manufacture. From observations, it is known that the drug manufacturing process has an adiabatic process where the resulting mass balance has the equation mass in = mass out and there is no chemical reaction that takes place. In the drying process, the heat balance can be calculated because this process produces heat which requires a certain amount of energy in the process. The drying machine used is an FBD (Fluidized Bed Dryer) machine which requires a certain amount of power so that the efficiency of this machine can be known to maximize the process.
An Algorithm for Finding the Generalized Chebyshev Center of Sets Defined via Their Support Functions
Authors: Arkhipov P. A. ,   Institute of Science and Technology Austria
Published: August 2024

This paper is dedicated to an optimization problem. Let A, B ⊂ R n be compact convex sets. Consider the minimal number t 0 > 0 such that t 0B covers A after a shift to a vector x 0 ∈ R n. The goal is to find t 0 and x 0 . In the special case of B being a unit ball centered at zero, x 0 and t 0 are known as the Chebyshev center and the Chebyshev radius of A. This paper focuses on the case in which A and B are defined with their black-box support functions. An algorithm for solving such problems efficiently is suggested. The algorithm has a superlinear convergence rate, and it can solve hundred-dimensional test problems in a reasonable time, but some additional conditions on A and B are required to guarantee the presence of convergence. Additionally, the behavior of the algorithm for a simple special case is investigated, which leads to a number of theoretical results. Perturbations of this special case are also studied.

Coordination in multiagent systems with information influences is studied. In particular, a model of multiagent system in which information is transmitted with a constant delay for all agents is studied. Using the Nyquist criterion applied by Tsypkin for systems with delayed feedback, a formula is obtained for the boundary value of time-delay which is included as a parameter in the system of differential equations with an asymmetric constant Laplacian matrix. The condition of independence of stability from time-delay is founded. The results obtained generalize some previously results and can be applied in coordination analysis in a multiagent systems with complex protocol.

Energi angin adalah sumber daya yang sangat berlimpah dan terbarukan yang dapat digunakan untuk mengoperasikan suatu mesin dan menghasilkan energy listrik. Turbin angin adalah bagian dari peralatan mekanis yang dimaksud. Terbukti bahwa Indonesia memiliki kecepatan angin yang relatif sedang dengan kecepatan angin rata-rata 2 m/s hingga 6 m/s. Di negara ini, laju pertumbuhan penduduk dan kebutuhan energi listrik meningkat, namun produksi riil dari sektor energi tidak dapat mengimbangi laju konsumsi energi yang terus meningkat. Batu bara, minyak, dan gas alam masih menjadi sumber energi utama di negara ini hingga saat ini. Jumlah energi, terutama minyak bumi, menjadi semakin langka, dan cadangan energi fosil semakin menipis dan tidak dapat diandalkan. Maka untuk menalangi energi yang terbatas tersebut kita dapat menggunakan energi angin sebagai sumber dalam menghasilkan energi listrik yang mana energi angin ini sendiri energi yang jumlahnya tak terbatas.

Authors: Kaltsa Maria , Tsolaki Anthoula , Lazarou Ioulietta , Mittas Ilias , Papageorgiou Mairi , Papadopoulou Despina , Tsimpli Ianthi Maria , Tsolaki Magda
Published: August 2024

Background:

Earlier research focuses primarily on the cognitive changes due to Alzheimer’s disease (AD); however, little is known with regard to changes in language competence across the lifespan.

Objective:

The present study aims to investigate the decline of language skills at the grammatical and syntactic levels due to changes in cognitive function.

Methods:

We administered the Litmus Sentence Repetition Task (SRT) to 150 native speakers of Greek who fall into five groups: 1) young healthy speakers, 2) cognitively intact elder healthy speakers, 3) speakers with subjective cognitive impairment (SCI), 4) speakers with mild cognitive impairment (MCI); and 5) speakers with AD dementia at the mild/moderate stages. All participants underwent a physical and neurological examination and cognitive screening with a standardized neuropsychological battery to assess cognitive status comprehensively and evaluate aspects like working memory, executive function, attention and memory to appropriately classify them.

Results:

The data analysis revealed that the SRT had high discriminatory value in the development of AD; specifically, both accuracy and grammaticality indices were related to cognitive decline. Additionally, syntax significantly affected the performance of speakers with structures such as clitics being particularly challenging and in most structures the performance of speakers with MCI drops significantly compared to speakers with SCI.

Conclusions:

Linguistic indices revealed subtle early signs of cognitive decline that can be helpful in the early detection of AD, thus facilitating the clinical process offering support to language-based assessment tools such as sentence repetition, a non-invasive type of assessment to evaluate symptoms of AD.

METHODS:

Endothelial cells were induced by ox-LDL. DDX5, pri-miR-640, pre-miR-640, miR-640, and SOX6 expressions were analyzed by RT-qPCR and Western blot. DDX5 expression was intervened by shRNA, followed by CCK-8 analysis of proliferation, flow cytometry detection of apoptosis, and tube formation assay analysis of angiogenic potential of cells. The binding between DDX5 and pri-miR-640 was determined by RIP, and the pri-miR-640 RNA stability was measured after actinomycin D treatment. Dual-luciferase assay verified the targeting relationship between miR-640 and SOX6.

RESULTS:

DDX5 and miR-640 were highly expressed while SOX6 was poorly expressed in ox-LDL-induced endothelial cells. Silence of DDX5 augmented cell proliferation, abated apoptosis, and facilitated angiogenesis. Mechanistically, RNA binding protein DDX5 elevated miR-640 expression by weakening the degradation of pri-miR-640, thereby reducing SOX6 expression. Combined experimental results indicated that overexpression of miR-640 or low expression of SOX6 offset the protective effect of DDX5 silencing on cell injury.

CONCLUSION:

DDX5 elevates miR-640 expression by repressing the degradation of pri-miR-640 and then reduces SOX6 expression, thus exacerbating ox-LDL-induced endothelial cell injury.
Collaborative optimization of multi-physical fields for composite electromagnetic linear actuators
Authors: Fan Xinyu , Zhu Yanbing
Published: August 2024

The composite electromagnetic linear actuator features a co-axial integrated design that merges the moving coil and moving iron actuator types. This design leads to significant interactions among electrical, magnetic, and thermal fields during operation, which in turn affect energy consumption and temperature increases. To further improve the material utilization rate of the actuator and optimize its comprehensive performance, such as force density and temperature rise, a multi-physical field collaborative optimization method was proposed. First, the energy consumption and temperature rise mechanisms of the actuator were analyzed. The bidirectional coupling relationships of multi-physical fields during its operation are studied. Simulations and experiments were conducted to establish the rules governing the spatiotemporal evolution of energy consumption and temperature fluctuations under standard operational conditions. Based on this, a system-level collaborative optimization model for the actuator was established. Sensitivity analysis helped segregate the design variables into system-level and independent categories. Subsequently, using a multi-objective genetic algorithm, the optimal parameter settings were determined. The optimization results revealed that the force constant of the main driving components increased by 5.4%, and the average temperature of the coil decreased by 6.3%; additionally, the starting force of auxiliary components increased by 2.3%, and the temperature of the yoke decreased by 0.8%.

Background:

Exercise promotion interventions for people with Parkinson’s disease (PD) are often offered on a face-to-face basis, follow a generic “one-size-fit-all” approach, and are not typically delivered at diagnosis. Considering PD’s heterogenous nature, the existing evidence on the merits of exercise on symptom management and the expressed wishes of people living with PD for access to timely and tailored evidence-based information, there is a demand for interventions that are easily accessible, scalable and co-designed with people living with PD.

Objective:

Evaluate the feasibility and acceptability of a co-designed digital intervention promoting exercise and physical activity, in people newly diagnosed with PD.

Methods:

Thirty people living with PD for less than one year participated in an assessor-blinded randomized feasibility trial from June 2022 to April 2023. The intervention group received the 8-week Knowledge, Exercise Efficacy and Participation (KEEP) intervention comprising 6 interactive digital modules and 4 online live group discussions facilitated by a specialist physiotherapist. Assessments were performed at baseline, post intervention and at 6-month follow up.

Results:

Thirty participants were recruited to target with a 64% recruitment rate (30/47). All but one participant completed the 6-month follow-up assessment. There was high retention (97%), module completion (91%), and online discussion attendance (88%). Outcome measure collection was feasible, including accelerometer data with a daily average wear time of 23.9 hours (SD:0.295).

Conclusions:

The KEEP intervention was feasible and acceptable in people newly diagnosed with PD. A larger trial is needed to assess intervention efficacy and correlation between knowledge, self-efficacy, and activity levels.
Advice to People with Parkinson’s in My Clinic: Orthostatic Hypotension
Authors: Lamotte Guillaume , McKee Kathleen E. , Luthra Nijee S. , Corcos Daniel M.
Published: August 2024

Orthostatic hypotension (OH) is the most common manifestation of cardiovascular autonomic dysfunction in Parkinson’s disease. In this viewpoint, we discuss five practical questions regarding OH in Parkinson’s disease: 1) How common is the problem? 2) Why should people with Parkinson’s disease and providers care about OH? 3) What are the symptoms of OH? 4) How to confirm a diagnosis of OH? And 5) How to treat OH? OH is an important non-motor symptom of Parkinson’s disease for which we have available treatments to significantly mitigate morbidity and possibly positively impact the disease course.
Employment barriers experienced at different job acquisition stages by people with and without disabilities

Published: August 2024

BACKGROUND: Employment barriers experienced by people with disabilities are well-documented by researchers. A closer look at the nature of these barriers at different stages of the job acquisition process may help to understand and address current challenges. OBJECTIVE: To understand how employment barriers differ for job seekers with and without disabilities; the impact of disability type; and are job acquisition barriers most salient, when looking for, applying to, or accepting a position. METHODS: 3,021 working-age adults (including 1,491 adults with disabilities) from a Qualtrics opt-in panel completed an online survey about employment status, job search barriers, and demographic factors (including disability). Logistic regression predicted odds of experiencing a job search barrier based on disability and other sociodemographic factors. RESULTS: Most job seekers reported barriers to employment, with disability being the strongest predictor. While the types of barriers experienced at all stages of the job search were similar for people with and without disabilities, people with disabilities experienced barriers significantly more often. CONCLUSION: Employment barriers among people with and without disabilities are similar in nature but vary by degree. Improvements in transportation and better alignment between education, training, and the job market may benefit all job seekers.

Published: August 2024

BACKGROUND: Innovations in healthcare technologies have the potential to address challenges, including the monitoring of fluid balance. OBJECTIVE: This study aims to evaluate the functionality and accuracy of a digital technology compared to standard manual documentation in a real-life setting. METHODS: The digital technology, LICENSE, was designed to calculate fluid balance using data collected from devices measuring urine, oral and intravenous fluids. Participating patients were connected to the LICENSE system, which transmitted data wirelessly to a database. These data were compared to the nursing staff’s manual measurements documented in the electronic patient record according to their usual practice. RESULTS: We included 55 patients in the Urology Department needing fluid balance charting and observed them for an average of 22.9 hours. We found a mean difference of -44.2 ml in total fluid balance between the two methods. Differences ranged from -2230 ml to 2695 ml, with a divergence exceeding 500 ml in 57.4% of cases. The primary source of error was inaccurate or omitted manual documentation. However, errors were also identified in the oral LICENSE device. CONCLUSIONS: When used correctly, the LICENSE system performs satisfactorily in measuring urine and intravenous fluids, although the oral device requires revision due to identified errors.
The impact of artificial intelligence in the diagnosis and management of acoustic neuroma: A systematic review
Authors: Alsaleh Hadeel
Published: August 2024

BACKGROUND: Schwann cell sheaths are the source of benign, slowly expanding tumours known as acoustic neuromas (AN). The diagnostic and treatment approaches for AN must be patient-centered, taking into account unique factors and preferences. OBJECTIVE: The purpose of this study is to investigate how machine learning and artificial intelligence (AI) can revolutionise AN management and diagnostic procedures. METHODS: A thorough systematic review that included peer-reviewed material from public databases was carried out. Publications on AN, AI, and deep learning up until December 2023 were included in the review’s purview. RESULTS: Based on our analysis, AI models for volume estimation, segmentation, tumour type differentiation, and separation from healthy tissues have been developed successfully. Developments in computational biology imply that AI can be used effectively in a variety of fields, including quality of life evaluations, monitoring, robotic-assisted surgery, feature extraction, radiomics, image analysis, clinical decision support systems, and treatment planning. CONCLUSION: For better AN diagnosis and treatment, a variety of imaging modalities require the development of strong, flexible AI models that can handle heterogeneous imaging data. Subsequent investigations ought to concentrate on reproducing findings in order to standardise AI approaches, which could transform their use in medical environments.
