Prediction of Mild Cognitive Impairment Status: Pilot Study of Machine Learning Models Based on Longitudinal Data From Fitness Trackers
Authors: Xu Qidi , Kim Yejin , Chung Karen , Schulz Paul , Gottlieb Assaf 
Published: June 2024

Background
Early signs of Alzheimer disease (AD) are difficult to detect, causing diagnoses to be significantly delayed to time points when brain damage has already occurred and current experimental treatments have little effect on slowing disease progression. Tracking cognitive decline at early stages is critical for patients to make lifestyle changes and consider new and experimental therapies. Frequently studied biomarkers are invasive and costly and are limited for predicting conversion from normal to mild cognitive impairment (MCI).

Objective
This study aimed to use data collected from fitness trackers to predict MCI status.

Methods
In this pilot study, fitness trackers were worn by 20 participants: 12 patients with MCI and 8 age-matched controls. We collected physical activity, heart rate, and sleep data from each participant for up to 1 month and further developed a machine learning model to predict MCI status.

Results
Our machine learning model was able to perfectly separate between MCI and controls (area under the curve=1.0). The top predictive features from the model included peak, cardio, and fat burn heart rate zones; resting heart rate; average deep sleep time; and total light activity time.

Conclusions
Our results suggest that a longitudinal digital biomarker differentiates between controls and patients with MCI in a very cost-effective and noninvasive way and hence may be very useful for identifying patients with very early AD who can benefit from clinical trials and new, disease-modifying therapies.
Investigating snow sinks on level sea ice in the Arctic

Published: June 2024

We examined snow sinks caused by snow and sea ice interactions (snow-ice
formation and sub-parcel snow mass redistribution) on level sea ice in
the Arctic. We coupled SnowModel-LG, a modeling system adapted for snow
depth and density reconstruction over sea ice, with HIGHTSI, a 1-D
thermodynamic sea ice model, to create SMLG_HS. Pan-Arctic model
simulations spanned from 1 August 1980 through 31 July 2022. Evaluation
of SMLG_HS against snow depth, snow-ice, and sea ice thickness
observations highlighted the importance of snow mass changes due to snow
redistribution processes. Without accounting for these processes, snow
on level ice was overestimated, resulting in underestimation of level
ice thickness and overestimation of snow-ice thickness. We show that
snow depth on level ice needs to be reduced by 40 % to simulate both
snow and level ice thicknesses realistically. Guided by this result, we
re-evaluated snow-ice formation. Our findings suggest that, on average
over the whole Arctic, snow sinks on level sea ice can reduce snow depth
by 3.5 % and increase snow density by 2.3 %.

Published: June 2024

Penelitian ini berfokus pada perbandingan dua metode hisab dalam penetapan awal waktu salat, yakni metode hisab menurut Rinto Anugraha dan metode menurut sistem ephemeris. Penelitian ini tergolong dalam penelitian kepustakaan (library reserch) dengan pendekatan deskriptif dengan tujuan untuk: (1) mengetahui perbandingan metode hisab menurut Rinto Anugraha dan sistem ephemeris (2) mengetahui tingkat akurasi dari metode hisab menurut Rinto Anugraha dan sistem ephemeris. Dari penelitian yang dilakukan didapatkan bahwa metode hisab menurut Rinto Anugraha menggunakan bahasa pemrograman excel sedangkan sistem ephemeris menggunakan bahasa pemrograman kalkulator dan menghasilkan hasil hisab yang berbeda pula yang disebabkan karena nilai data yang digunakan juga berbeda utamanya nilai data deklinasi matahari dan equation of time. Namun kedua metode hisab tersebut tergolong metode hisab yang akurat karena ketepatan akurasi yang cukup tinggi itu terlihat dari hasil yang diperoleh yang hanya berkisar beberapa menit namun hal tersebut dapat diabaikan. Sebaiknya dalam melakukan perhitungan perlunya ketelitian dalam penginputan nilai data, baik pada program excel maupun kalkulator scientific.

Predicting Talent: Interaction between Potential, Competencies, and Bias
Authors: Aras Rezky Ariany , Bellani Elvita , Wahyuni Sri , Sandy Grestin , Arfah Triani 
Published: June 2024

Abstract
The psychological attributes associated with both psychological potential and managerial competence are regarded as valuable assets for any company. Consequently, it is in the best interest of companies to actively search for the most potential candidates and develop their competencies. Organizations expend substantial resources to assess the potential of prospective employees during the recruitment process. This research aims to evaluate the extent to which employees' potential can predict their competencies. We assessed candidates' potential using self-report scales measuring grit and a growth mindset, while competencies in achieving results and managing change were evaluated through the assessment center method. The data was collected from 155 civil servants employed by the Makassar City Government. The findings reveal that potential does not significantly influence employees' competencies, whether it be Grit for results orientation or Growth mindset for change management competence. After conducting correlation tests between grit and growth mindset to social desirability bias, we found varied results with Grit (r= 0.1718, p = 0.03248) and growth mindset (r=0.0703, p-value = 0.3847), suggesting diverse correlations between the investigated variables. In light of these results, we recommend a reevaluation of the practice of relying on potential as a predictor of competence.
Exploring Ethics in South African Municipal Procurement: Professionalism, Compliance, and Ethical Dimensions Interface
Authors: Jam Ayanda , Bayat Mohammed Sayeed , Rulashe Tando 
Published: June 2024

Abstract
The local government is close to the people who thus, heavily rely on it for basic needs, a legislative imperative enshrined in the supreme law of the Republic of South Africa, the Constitution of 1996. Its purpose is to supply goods and services and encourage the participation of citizens in the realisation of policy objectives. This paper is one-third of a three-series composition sought through a conceptual and theoretical perspective to interrogate the ethical dimensions in which the public service exists within the interface of professionalism and compliance with municipal procurement processes and procedures. While the local sphere of government is crucial in the democratization and intensification of mass participation, there has been a rise in incidents of corruption and fraud, fruitless and wasteful expenditure, and the misuse and misdirection of funds, which gradually erode public trust. This paper employed an interpretivism paradigm and a qualitative approach, and it relied on secondary data The paper found that the erosion of public trust leads to citizens violently protesting, demanding better service delivery and that service delivery is likely to decline when funds are misappropriated since municipalities rely on the procurement of goods and services to initiate public service delivery. Furthermore, the paper found while South Africa has sound, comprehensive and clear legislative policy frameworks that regulate public procurement; implementation remains a challenge.

Published: June 2024

Abstract
Despite the widespread adoption of the Routing Protocol for Low-power and Lossy Networks (RPL) in IoT environments, its inherent limitations in addressing security vulnerabilities have left IoT networks vulnerable to ongoing attacks. This paper introduces a novel intrusion detection system tailored specifically for IoT networks, with a focus on mitigating attacks at the network’s edge. The study presents the Hybrid Rank Attack (HRA), a sophisticated threat exploiting RPL vulnerabilities by alternately advertising decreased and increased rank values in control messages. Extensive experimentation evaluates the detrimental effects of HRA on critical network metrics including exchanged messages, energy consumption, PDR, latency, and memory footprint. Additionally, a lightweight and distributed countermeasure algorithm is proposed to effectively mitigate the impact of HRA. Simulation-based evaluations demonstrate significant reductions in control overhead (68.7%) and energy consumption (61.83%), with minimal additional RAM utilization (1.05%). This lightweight solution enhances the resilience of RPL-based IoT networks against HRA threats.

Published: June 2024

Abstract
The aim of the study was to determine the effect of hyperbaric oxygen on the growth and metabolism of Pseudomonas aeruginosa in vitro. The experiments were carried out on agar media and blood culture plates. Bacterial culture plates were exposed to hyperbaric oxygen under varying conditions of pressure and exposure time. Significant inhibition of bacterial growth and proteolytic activity was observed. Hyperbaric-treated pathogens also showed less virulence after the infection of experimental animals.

Authors: Wolański Władysław , Pełka Stanisław , Ramisch Józef 
Published: June 2024

Abstract
This paper presents the results of a pilot programme to include psychological tests in the recruitment rules for candidates for military divers and scuba divers. A total of 207 candidates to undertake training at the Polish Army Divers and Scuba Divers Training Centre were examined. They were subjected to tests of mental fitness, tests examining personality traits, tests of psychomotor fitness and tests of general fitness.
Numerous psychological contraindications to undertake diving training and service were found; the most common was a low degree of mental fitness.
In conclusion, it was suggested that, following the example of other countries, psychological testing should be included in the selection of candidates for divers. The results of the tests, although not obligatory, were partly taken into account in the opinion issued by the Military Medical and Maritime Commission.

Published: June 2024

Introduction: The purpose of this article is to find out how the strategic action field capacity of the Indonesian bureaucracy on bureaucratic simplification has been implemented.

Literature Review: The meaning of delayering, with reference to such metaphors, is commonly taken to describe the planned vertical compression of various levels of the managerial hierarchy, including the wholesale removal of one or more levels of managerial or supervisory staff from an organization's personnel roster. (Keuning and Opheij, 1994; Miller and Longair, 1985; Wheatley, 1992).

Method: This research uses qualitative research through primary data collection through interviews and secondary data through literature study.

Result and Discussion: The results show that bureaucratic simplification has not been proven effective in improving the performance of the bureaucracy in Indonesia, it is still only at the stage of fulfilling administrative obligations.

Conclusions: Key findings as novelty in studies related to implementation of bureaucratic policy researchers with locus Ministry of Home Affairs, Ministries of Religion, Ministry for Rural and Rural Development of the Remnant, and Ministries for State Apparatus Disclosure and Reforms The bureaucracy suggests that organizational capacity must be derived from individual capacity, as the primary capital of an organization before making organizational change.

Authors: Maz-Machado Alexander , Dalagkozi Paraskevi , Valenzuela Gema Linde , Caicedo-Quiroz Rosangela 
Published: June 2024

Objective: The objective of this study is to investigate the degree of satisfaction of nurses who participated in lifelong learning programs and to record the frequency of use of new knowledge in everyday nursing practice.

Theoretical Framework: Improving the quality of care and patient safety is a constantly evolving process, and it relies on nurses' active participation in developing knowledge and nursing practice. To fulfill the new requirements of quality, responsibility, and effectiveness of nurses' duties, they must continuously update their understanding, techniques, and developments associated with the profession. Most nurses recognize the need to update their knowledge, and the number of those investing in lifelong learning programs is steadily increasing. However, despite acknowledging the benefits of monitoring these programs, they seem dissatisfied with their quality and content.

Method: Two of the most widespread approaches, qualitative and quantitative, were applied. The qualitative approach involved 13 nurses serving in public health structures in Greece. The research tool used was a guide for semi-structured interviews, and the data was processed using the method of thematic analysis. The quantitative approach involved 203 nurses serving in public health structures in Greece.

Results and Discussion: According to a study, nurses who participated in lifelong learning programs reported high satisfaction levels regarding the benefits they gained from the courses they attended. However, the study also revealed issues with the organisation and content of the programs, as well as the integration of the new knowledge into their everyday nursing practice.

Research Implications: To attain a profound sense of satisfaction, the chosen courses must align with individual interests and offer opportunities to apply theoretical knowledge in practical contexts. To enhance the overall understanding of fulfilment, the individuals responsible for designing lifelong learning programs should prioritise hands-on training for nurses based on the latest assimilated knowledge.

Originality/Value: This study contributes to assessing the applicability of continuing education in daily work practice. The relevance and value of this research highlights the importance of continuing education for nursing staff in Greece.

Objective: Admission to university means a change in lifestyles for young people, who are burdened by factors such as emotional problems, stress and must develop the skills to face positively their university studies developing their academic engagement [EA]. In this context, the aim of this study was to determine the relationship between the employment situation and academic engagement in university students.

Methods: A quantitative methodology with a cross-sectional correlational design was used. The sample consisted of 429 university students, male and female, selected by a random probabilistic criterion. The Utrecht Work Engagement Scale was used to collect information. The statistical test used corresponds to the Spearman correlation.

Results: The main results reveal that the level of EE of university students is average, since 48.5% identified with this level. In the dimension of vigor of the EA, high percentages of university students with a medium level of engagement with a tendency to low and very low levels were found. In the dimension of dedication, university students were characterized by having a medium level with a tendency to high and very high levels, while in the dimension of absorption, university students are characterized by having a medium level of engagement with a tendency to low levels. On the other hand, the employment situation of university students reveals that 69% study and work, while 31% only study.

Conclusion: It is concluded that there is a moderate relationship between the employment situation and the EA since the p value obtained is less than the proposed significance value (0.025<0.050).
