Purpose: to identify the intraretinal hyperreflective foci (HRF), their specific characteristics, localization features and correlations with the duration of the disease, type of course and previous episodes of optic neuritis (ON) in multiple sclerosis (MS) patients using a high-resolution OCT scanning protocol. Materials and methods. The study included 160 patients (318 eyes) divided into 8 groups, i.e. Group 1: 44 eyes (13.84 %) — MS onset without a history of ON; Group 2: 30 eyes (9.43 %) — debut of MS with ON; Group 3: 56 eyes (17.61 %) — relapsing-remitting MS (RRMS) lasting ≤ 10 years without ON; Group 4: 38 eyes (11.95 %) — RRMS lasting ≤ 10 years with ON; Group 5: 49 eyes (15.41 %) — RRMS lasting ˃ 10 years without ON; Group 6: 37 eyes (11.63 %) — RRMS lasting ˃ 10 years with ON; Group 7: 34 eyes (10.69 %) — secondary progressive MS (SPMS) without ON; Group 8: 30 eyes (9.43 %) — SPMS with ON. Results. HRF were identified in all groups, at the levels of both the outer nuclear layer (ONL) and the inner nuclear layer (INL). Their number increased depending on the duration, type of course, and the presence of ON history. The thickness of the inner layers of the retina corresponded to the average normative indicators in the group with the onset of MS without ON. In the SPMS group after ON, a decrease in the total thickness of ganglions retinal cells layer (GCL) and the inner plexiform layer (IPL) was noted, showing minimal values of both avGCL + IPL (65.83 ± 8.27 μm) and avRNFL (76.37 ± 6.94 μm). High inverse correlations were revealed between avGCL + IPL and the amount of GRF at the levels of ONL and INL (-0.82 and -0.85, respectively, p = 0.01). Conclusions. The presence and quantity of HRF can be considered as a prognostic non-invasive biomarker associated with the duration of MS and the history of ON, allowing one to visualize the penetration of microglia activated by immune cells into the unmyelinated part of the central nervous system, helpful in elucidating their role in the pathogenesis and progression of the disease.

ABSTRACT

Satellite precipitation estimations (SPEs) have become important to estimate rainfall in remote and inaccessible areas. The study evaluates two high-resolution SPEs (IMERG and CHIRPS) in Peninsular Malaysia from 2011 to 2020. In situ rain gauge observation data were used as reference data, and a series of statistic indices were used to evaluate the performance of SPEs. In order to identify the source of error in the SPEs, an error decomposition technique was proposed whereby the bias is segregated into four different independent components. The study found that IMERG outperformed CHIRPS, with both satellites performing well in the east coast region but poor in the central region. A superior correlation between the SPEs and rain gauge observations was found during the northeast monsoon. The false bias has shown the widest range compared to other error components, indicating that it is the main contributor to the total bias of both SPEs in Peninsular Malaysia.

ABSTRACT

In water-scarcity contexts, girls fetching water are exposed to gender-based violence (GBV), for which prevalence, types, and forms were unknown in the Peri-Urban Settings of Kinshasa. A cross-sectional study using multi-stage random sampling technique to select 684 adolescent girls was conducted to assess the extent of water scarcity and GBV affecting adolescent girls while fetching water. Findings indicate that 98.2% of adolescent girls were dealing with water shortage; 99.9% experienced at least one type of GBV, of which 97.1, 95.5, and 44.9% experienced sexual, psychological, and physical violence, respectively. Moral violence was more frequent at water points; physical violence in the household, while sexual violence was prevalent on the water route. Adolescent girls' age, weekly involvement in water collection, and distance were found to be the main factors associated with GBV, whereas reducing the number of daily round-trips, the distance travelled, and time devoted to water collection were found to be mitigating factors limiting GBV experience among adolescent girls. Policies promoting the at-home provision of water and community awareness-raising interventions will mitigate the GBV incidence.

On the effectiveness of using carbamide-based salt baths for low-temperature cyanidation of improved carbon and alloy steels
Authors: Kostin N. N. , Kolmykov V. I. , Kostin N. A. , Kolmykov D. V. 
Published: July 2024

Purpose. A study of cyanidation of improved carbon and alloy steels of grades 30, 30HGT, 30H13 at a temperature of 550–580 °C was carried out in baths based on carbamide and sodium carbonate. Recommendations on the use of these baths for surface hardening of carbon and alloyed improved steels used for the manufacture of machine parts are formulated. Methods. The microstructure of the diffusion layer of steels on transverse sections was studied using a Quanta FEG – 650 electron scanning microscope with an EBCD focused ion beam microanalysis system. Cyanide wear tests were performed under friction conditions analogous to those of die tools. The wear resistance of the carbonitrided samples was investigated on a SMTs-2 friction machine. The tests were performed under both dry friction and boundary friction conditions. Results. The high efficiency of the proposed bath composition at a given temperature has been experimentally shown. As a result of cyanidation, modified layers saturated with solid inclusions (ε-phases) are formed on the surface of steels, characterized by high hardness, low coefficient of friction and high wear resistance. Conclusion. According to the results of the conducted research, it can be concluded that low-temperature cyanidation of improved steels of various grades can be carried out in cyanide-free salt baths. The optimal composition of the cyanide bath is 40% carbamide (NH2)2CO; 40 % soda ash Na2CO3 and 20 % NaCl table salt. The proposed bath does not contain toxic and scarce components, therefore it is environmentally safe and very cheap and can be used with great effect in machine-building, repair and tool industries.

Published: July 2024

Abstract

Background
As Japan is the world’s fastest-aging society with a declining population, it is challenging to secure human resources for care providers. Therefore, the Japanese government is promoting digital transformation and the use of nursing care equipment, including nonwearable devices that monitor heart and respiratory rates. However, the feasibility of monitoring heart and respiratory rates with nonwearable devices and the consistency of the rates measured have not been reported.

Objective
In this study, we focused on a sheet-type nonwearable device (Safety Sheep Sensor) introduced in many nursing homes. We evaluated the feasibility of monitoring heart rate (HR) and respiratory rate (RR) continuously using nonwearable devices and the consistency of the HR and RR measured.

Methods
A sheet-type nonwearable device that measured HR and RR every minute through body vibrations was placed under the mattress of each participant. The participants in study 1 were healthy individuals aged 20‐60 years (n=21), while those in study 2 were older adults living in multidwelling houses and required nursing care (n=20). The HR was measured using standard methods by the nurse and using the wearable device (Silmee Bar-type Lite sensor), and RR was measured by the nurse. The primary outcome was the mean difference in HR and RR between nonwearable devices and standard methods.

Results
The mean difference in HR was −0.32 (SD 3.12) in study 1 and 0.04 (SD: 3.98) in study 2; both the differences were within the predefined accepted discrepancies (<5 beats/min). The mean difference in RR was −0.98 (SD 3.01) in study 1 and −0.49 (SD 2.40) in study 2; both the differences were within the predefined accepted discrepancies (3 breaths/min).

Conclusions
HR and RR measurements obtained using the nonwearable devices and the standard method were similar. Continuous monitoring of vital signs using nonwearable devices can aid in the early detection of abnormal conditions in older people.

Emisión de brotes y relación con clima en pitahaya (Selenicereus costaricensis; Cactaceae)
Authors: Monge-Pérez José Eladio , Loría-Coto Michelle 
Published: July 2024

Introducción: Para la producción de frutales, es importante conocer la relación entre las variables climáticas y la fenología del cultivo. Hay pocos estudios sobre este tema en el cultivo de pitahaya en Costa Rica. Objetivo: Evaluar el tipo de relación entre la emisión de brotes en el cultivo de pitahaya cv. San Ignacio y el clima. Métodos: Realizamos la investigación entre los años 2017 al 2019. Evaluamos las siguientes variables: número de brotes vegetativos (NBV), número de brotes reproductivos (NBR), temperatura promedio (Tp), mínima (Tmín) y máxima (Tmáx); humedad relativa (HR) y precipitación pluvial (P). Calculamos las correlaciones de Spearman entre variables. Resultados: No encontramos correlaciones estadísticamente significativas entre el NBV y las demás variables analizadas. Por otro lado, observamos una correlación positiva significativa entre el NBR y las variables de temperatura mínima (r=0,52**), precipitación (r=0,36*) y humedad relativa (r=0,33*). Estos resultados indican que a medida que aumentan la precipitación, la humedad relativa y la temperatura mínima, también aumenta la cantidad de brotes reproductivos. Identificamos adicionalmente correlaciones entre NBV, NBR y las variables climáticas durante los meses previos a la brotación. Conclusión: No se observó un patrón definido en la emisión de brotes vegetativos, mientras que la emisión de brotes reproductivos ocurrió principalmente durante las fases inicial y media de la temporada de lluvias. Además, se observó que generalmente, durante la emisión de brotes reproductivos, se producían pocos o ningún brote vegetativo.
Do Two Minds Think Alike? Efficiency Benefits from Common ERP Vendor Use in a Supply Chain
Authors: Barber Russell , Pinsker Robert , Walton Stephanie , Zhang Yiyang 
Published: July 2024

SYNOPSIS
Utilizing a common enterprise resource planning (ERP) vendor could improve supplier and customer performance by increasing supply chain information technology (IT) alignment, agility, and efficiency. However, supply chains could be hesitant to utilize a common ERP vendor for fear of intellectual capital loss, increased costs, and IT incapability with existing IT architecture. Relational view theory argues that information sharing and process integration advantages are achieved when supply chain partners share assets, knowledge, and capabilities through relation-specific investments, complementary resources, and knowledge sharing processes. We find evidence that common ERP vendor (CERPV) use is associated with greater supplier and customer efficiency, performance, and partnership strength. Our study directly examines the impact of CERPV use within a supply chain, adding to the limited accounting information systems’ evidence on the role of interorganizational ERP system investments on efficiency.

Published: July 2024

ABSTRACT
Based on a survey of U.S. AACSB-accredited accounting program chairs, we find that the current faculty shortage at the participants’ institutions is less severe than five years ago and less severe than it is expected to be over the next five years. Specialties with the greatest current shortage at the participants’ institutions are tax, accounting systems and data analytics, and audit. Participants view the overall U.S. accounting faculty labor market in balance today, but trending toward a slight shortage over the next five years. Both today and over the next five years, participants perceive a surplus of financial accounting faculty, and shortages in audit, tax, accounting systems and data analytics, and fraud/forensic accounting. Finally, we find that the accounting faculty shortage is much more severe at small, “Nonresearch Intensive” schools than at large, “Research Intensive” schools. We discuss insights for current and prospective doctoral students and others.
Stopping Hamburglars: Applying Effective Internal Control
Authors: Soonawalla Kazbi , Wakefield James 
Published: July 2024

ABSTRACT
Understanding effective internal control is vital for accounting and business students. Examples of fraud and loss through poor internal control are widespread in practice. The learning objectives of this teaching case focus on improving students’ ability to comprehensively evaluate internal control practices and suggest and justify new practices where applicable. The McDonald’s Monopoly fraud is a real-life example of a situation where multiple internal control failures had substantial financial and reputational consequences for McDonald’s, particularly its outsourcing partners involved in operationalizing the monopoly game. We use this factual case to illustrate control system shortcomings, allowing students to evaluate internal control and suggest internal control techniques with reference to all five components of the Committee of Sponsoring Organizations of the Treadway Commission (COSO) Internal Control—Integrated Framework.

Supervisor Impact on Employee Careers: The Role of Rating Differentiation
Authors: Künneke Judith 
Published: July 2024

ABSTRACT
Organizations invest heavily in supervision to increase the competitive advantage of their human capital. Although recent studies show that supervisors add value in general, it is not well understood what specific supervisory behaviors are relevant for employee career outcomes. To that end, this study explores the performance evaluation process and focuses on supervisors’ evaluation behavior. Interpreting a supervisor’s tendency to differentiate as a way of advancing employee development, I provide theory-consistent evidence revealing the relevance of differentiation for employee career outcomes. Using proprietary archival data, I demonstrate that differentiation relates positively to employees (1) performing more successfully in a new position upon promotion, (2) receiving a promotion to the next position, and (3) remaining in the organization. Therefore, this study presents novel and relevant evidence on the importance of specific supervisory behaviors in establishing effective human capital management practices.

Osteoartritis (OA) lutut merupakan penyakit yang sering ditemukan pada populasi lanjut usia dan dapat menjadi pemicu disabilitas. Tata laksana utama yang disarankan American College of Rheumatology adalah latihan fisiksedangkan analgetik golongan nonsteroidal anti-inflammatory drugs dan anti-inflamasi steroid intra-artikular diberikan jangka pendek untuk mengurangi gejala. Tujuan evidence-based case report adalah untuk menganalisis apakah injeksi steroid intra-artikular pada pasien OA lutut sebelum menjalani latihan fisik dapat membantu mengurangi nyeri OA. Data yang dianalisis adalah dari database Pubmed, Cochrane dan Embase menggunakan kata kunci atau medical subject headings. Setelah itu dilakukan telaah jurnal relevan yang terpilih. Dari ketiga studi tersebut didapatkan bahwa kombinasi terapi injeksi intra-artikular steroid dengan program latihan fisik sebelum menjalani program latihan fisik tidak memberikan perbaikan signifikan dibandingkan dengan subjek yang diberikan injeksi intra-artikular plasebo sebelum menjalani latihan fisik. Oleh karena itu, kombinasi terapi anti inflamasi dan program latihan fisik tidak kami rekomendasikan untuk terapi OA.
The Importance of Developing Self-Control to Improve Subjective Well-Being of Adolescents Living in Orphanage
Authors: Ulfah Khoiriya 
Published: July 2024

Subjective well-being is a person's perception of his life experience and affection for his life Diener (1984). Based on observations, teenagers who live in orphanages seem to want more attention. Adolescents basically enter a transitional period and need guidance and affection from their parents, but they cannot get this at the orphanage. This is very risky for the emergence of negative emotions which of course will interfere with their subjective well being. So that self-control is needed to reduce negative emotions that might occur to teenagers in the orphanage. Individuals who have good self-control will be able to express their emotions appropriately according to the circumstances they are facing. This study aims to determine the relationship between self-control and subjective well-being in adolescents living in orphanages in Pringsewu Regency. The sample in this study were 60 adolescents according to predetermined criteria, namely those who resided in the orphanage of Putri Tunas Harapan Aisyiyah and Putra Umul Mukmin Aisyah Binti Abubakar in Pringsewu Regency. The data collection method in this study was to use a scale and use the Product Moment correlation technique with the help of the SPSS 20.0 for windows program using Cronbach Alpha. The results of the correlation in this study are that there is a significant positive relationship between self-control and subjective well-being.Keywords: Self-Control, Subjective Well-Being, Adolescents
