Structural transformations of the labor market in the age of Artificial Intelligence
Authors: Barbaneagra Oxana
Published: May 2024

The extent of artificial intelligence can be realized by contributing to the scientific, technological, economic and social development and progress of humanity. While AI is driving growth in many industries and bringing economic benefits, it is causing deep disruption and structural transformations in the labor market, in both positive and negative ways. We are witnessing the replacement of job roles by AI-driven automation and a growing demand for professionals with AI expertise, new professions emerging that did not exist before. On the other hand, the introduction of technologies leads to the reduction of middle-skilled workers, increases the gap between low-wage and high-wage workers. Under these conditions, employees and employers must adapt to these challenges in the labor market that produce changes in the occupational structure by acquiring new skills.
Managerial implications for the sustainability of energy policies
Authors: Cojocaru Dana-Claudia , Onofrei Mihaela
Published: May 2024

In the 21st century, society is characterised by innovation, complexity and numerous challenges with multiple implications for citizens' lives. Political, economic, financial, environmental and social issues are constantly influencing the development trend of society. The most recent global events have demonstrated the weaknesses of contemporary societal arrangements, one of which is the dependence of economies on non-renewable energy sources. Today, in many economies, oil is the main energy resource and the reason for cooperation between certain countries, but also the reason for disputes between players in the international system. In this context, two interrelated concepts emerge - energy security and the managerial implications for decision-makers. These two concepts, which we have at our disposal at all times, are designed to achieve an integrated energy market, managing the resources at our disposal efficiently. Accordingly, the main purpose of our paper is to analyze two of the most important mechanisms we have at our disposal to ensure security and the climate for sustainable development. According to our results, policy makers have a major role to play in developing sustainable and quality energy policies. Despite the fact that policy makers often faced challenges in choosing the most appropriate and effective energy policy for their countries, they faced multiple challenges related to the energy sector and highlighted the importance of ensuring energy security.
Tools and mechanisms for achieving sustainable public procurement in the context of ensuring national economic security
Authors: Codreanu Alina
Published: May 2024

This study underscores the premise that national economic security is also described by the phenomenon of the public procurement contract, which will take into account the rigors imposed by the legislator, respecting the fundamental principles and capitalizing on concepts such as good management of public money, green procurement, wise procurement, control managerial quality, through the responsible involvement of all participating actors. The achievement of sustainable public procurement requires an extensive, complex process, which includes a set of effective tools and mechanisms. If we are to mention the public procurement contract and especially the procedures expressly provided by the Moldovan legislator, we can mention that this type of contract can be awarded through the following procedures: open tender; restricted tender; competitive dialogue; negotiated procedures; request for price offers; solution contest; acquisition in the case of social housing construction plans. The study includes a brief synthesis of the reasoned opinions of some authors, experts in the field of public procurement, regarding the development of the concept of ensuring economic security. The research methods used were varied: documentary analysis, comparative analysis, synthesis, the method of induction and deduction. The importance of knowing and capitalizing on tools and mechanisms for sustainable public procurement, in the context of ensuring national economic security, will take into account, first of all, the fundamental principle of the efficient use of public money, which will involve following a well-determined direction.

Analysis of interest groups that may matter at the level of the reform process of the most relevant international organizations
Authors: Iacob Corneliu-George , Miron Dumitru
Published: May 2024

The current international environment, viewed from a geopolitical and geoeconomic point of view, is characterized by unpredictability and heightened dynamism. After the Second World War, the theoretical and doctrinal landscape was marked by an increasing openness to the concepts of harmony, cooperation, structural peace, prohibition of war. The UN is a symbol of multilateralism and sustained worldwide efforts for peace, security and sustainable development. Strategic autonomy, national security and other non-economic objectives (environmental sustainability, protection of workers and human rights) motivate calls for collaboration between countries with similar political-economic values and systems. In today's conditions, security considerations have already become more prominent in trade relations. Since the end of the 90s, several scenarios have been proposed for the reform of the United Nations: the reform of the Security Council, the reform of the UN Secretariat, the financial reform, the reform of human rights, the reform of operational activities and, last but not least, the reform of the Economic Council and Social. The research methodology uses various research methods: the logical analysis method, the systemic method, the comparative method, the historical method, the situation analysis used in geopolitical theory and the stakeholder analysis to understand the positions and perspectives of the players (stakeholders) who have an interest and/or likely to be affected by a particular reform, as well as to outline the prospects for reform and how particular states/organizations might influence the outcome of the process.
Non-destructive rapid defect testing around curved head rivets without displacement of eddy current sensors

Published: May 2024

In the field of aeronautics, it is essential to ensure the structural integrity of aircraft components. Non-destructive testing (NDT) plays a crucial role in ensuring the safety and reliability of structures used in aeronautics as it enables the detection of defects and imperfections without damaging the inspected parts. Domed head rivets are commonly used in aeronautics to assemble multilayer structures due to their strength and ability to maintain the structural integrity of aircraft. However, inspecting these assembly areas can be challenging and presents unique challenges in terms of non-destructive testing due to the curved surface of the rivet, resulting in lift-off variation during surface scanning and a modification of the trajectory of eddy currents near the rivet. This can lead to changes in the response of eddy currents, complicating the accurate interpretation of test results. In recent years, researchers have focused on developing advanced eddy current testing methods to detect defects in complex structures, such as those found in aeronautics. In this work, we propose a promising solution to address both the shape of the rivet and the probe displacement issue during testing. We have developed a model based on the finite element method (FEM) using COMSOL Multiphysics for non-destructive testing through 3D imaging using a matrix of multiplexed multi-element eddy current sensors distributed over multiple layers around the rivet without the need for the displacement of this matrix and capable of adapting to the variation in the diameter of the domed head rivet. The non-displacement of the sensors eliminates parasitic signals that can lead to errors in the interpretation of obtained signals, and the multiplexed powering of the sensors eliminates the mutual inductance effect between adjacent coils.

Authors: Xu Haihui , Ge Zhiyuan , Ao Wenjie
Published: May 2024

This research delves into the application of the Autoregressive Integrated Moving Average (ARIMA) model for predicting climate change and its subsequent implications for decision-making within the insurance industry. The study introduces a comprehensive approach to forecast climatic variables such as temperature, rainfall, and relative humidity, which are critical factors in assessing insurance risks and formulating underwriting strategies. The ARIMA model, recognized for its efficacy in time series analysis, is employed to capture the seasonal patterns and trends in climatic data. The model is calibrated using historical weather records from two distinct regions, Dali and New York, to account for geographical variability in climate sensitivity. By integrating the model's predictions with economic indicators and industry-specific data, the research constructs a Weather Composite Index (WCI) that quantifies the potential impact of climate change on local economies and insurance claims. The paper meticulously describes the model's parameters, including the order of differencing (d), the number of autoregressive terms (p), and the number of moving average terms (q), which are selected to optimize the model's fit and predictive accuracy. The Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC) are utilized to evaluate and compare the performance of different ARIMA configurations, ensuring that the chosen model minimizes the forecast error and provides the most reliable predictions.

A Lightweight Object Detection Network for UAV Aerial Images
Authors: Tang Lin , Zhou Shunyong , Wang Xinjie
Published: May 2024

In order to solve the problems of poor detection algorithms, high network model complexity, and difficult deployment of algorithms in the field of aerial image target detection. In this paper, based on YOLOv7-tiny algorithm, a lightweight target detection network for UAV aerial images is designed. Partial convolutional PConv is introduced into the network, and the feature extraction block ELAN is improved, which reduces the computational volume of convolution and the number of model parameters in the feature extraction process, thus solving the problem of model lightweight. The feature fusion part of the network is optimal to improve the feature extraction ability of the network for small targets. At the same time, the large target detection layer in the original network is replaced with the small target detection layer in the aerial images, and the attention mechanism is embedded in the backbone network, which solves the problem of imperfect detection algorithms in aerial images. The loss function of the network is improved so that the prediction frames generated by the detection network and the truth frames match each other in the regression process, thus improving the training process of the network. The experimental results on the publicly available dataset VisDrone2019 dataset show that compared with the YOLOv7-tiny algorithm, the detection accuracy of the proposed model is improved by 0.7%, the recall R is improved by 2.2%, the F1 value is improved by 1.6%, the average detection accuracy mean is improved by 2.3%, and the number of parameters is reduced by 52.1%. Moreover, the image detection speed FPS reaches 66/f.s-1, which meets the real-time requirements of the aerial image detection model detection, and provides a research idea for the field of UAV aerial image detection.
Moral Hazard Analysis of Third Party Sewage Treatment
Authors: Lou Fangyuan
Published: May 2024

This paper uses the theoretical model of moral hazard and "tragedy of the Commons" and relevant analysis methods to analyze the discharge of production sewage into rivers by n production sewage enterprises, and the third-party treatment enterprises to treat the discharge of production sewage enterprises, and obtains the Nash equilibrium sewage discharge of each production sewage enterprise to maximize its own payment and the maximum social benefit. In the case of information asymmetry between two kinds of enterprises and between two kinds of enterprises and the government, there is moral hazard, and enterprises will harm social benefits for their own interests, which is not Pareto optimal. It concludes that it is necessary for the government to strengthen regulation, and puts forward relevant suggestions such as government regulation and corresponding incentive measures to improve information asymmetry, restrain the moral hazard of production and pollutant discharge enterprises and third-party enterprises, effectively control river pollution, protect water resources, and achieve sustainable development.

IN SEARCH OF EQUITY: ORISSAN TRIBAL HISTORIOGRAPHY’S SEARCH FOR JUSTICE AGAINST COLONIAL INJUSTICE
Authors: DASH BAIRA GANJAN
Published: May 2024

Before the development of subaltern historiography, history was always an elite pursuit. Subaltern historiography has played an important role in de-elitising history and bringing forth the facts of socio-economic aspects and political events during the colonial period. In colonial Orissa, there were numerous subaltern movements in general, and tribal insurgencies in particular, all aiming for some or other form of independence from the clutch of landed aristocracy, local rajas, or the British. Tribals played a significant political role in Orissa’s freedom struggle in 19th and 20th centuries. They were not at all backward in colonial Orissa’s prajamandal movements. But it is a farce that, even after a long interval, just a few tribal leaders have gained prominence in history, which shows a gap in political history and a grave intellectual injustice. Colonial historiography portrayed tribals as criminals and blind-believers with negative activities. But the influence of Marxist and Subaltern approach has changed the historiographical scenario in the post-independent phase, which is evidenced from the extensive studies on socio-economic and cultural life of the tribals. Despite extensive studies, political history of tribals has received less attention in comparison to socio-economic history. Similarly, the history of science and technological knowledge in proverbs, health care practices, animal husbandry have not yet explored. Travesty, we are obliged to rely exclusively on inadequate colonial documents, which appear to be biased, due to a lack of indigenous records. As a result, the need of oral source, vernacular sources and artefacts preserved in museums are felt significantly. Intensive research within the conceptual framework of an interdisciplinary approach is also required to learn more about their other aspects of life and for bringing an intellectual justice.

Authors: Knowles Regina , Jones Carol , Webb Blake , Welsh Deborah , Mills Peter
Published: May 2024

Objective: The study aims to determine the facilitators and barriers to conducting large-scale CRM-based training in a national health care system (VHA). While there are some studies on this topic, none review training in a federal system or provide data on changes within the system.Methods: Design: Focus Groups collecting qualitative data. Review Methods: We held focus-groups for Clinical Team Training (CTT) facility Points of Contact (POC) and CTT Master Trainers. Responses were collected live and presented to all participants in each focus group session to ensure participant comfort and accuracy. All subgroup leaders agreed on iteratively and qualitatively reviewing participant responses from the four open-ended and three poll questions. Each subgroup leader was assigned a question to conduct a preliminary review of participant responses. After the initial review, a second leader also reviewed the participant responses. Over multiple iterations, themes emerged and were formalized by the team.Results: The focus groups revealed that Leadership engagement in cultural change is imperative. The focus groups also identified that language and examples used in the curriculum may have inadvertently marginalized individuals by making some non-clinical team members feel excluded as part of the team. Our results support the need for highly visible leadership engagement, adequate time to undertake and complete projects, and overcoming skepticism. See table 1 for themes from each question.Conclusions: Qualitative analysis revealed that Leadership engagement in cultural change is imperative. Focus groups identified that specific language and examples used in the curriculum may have inadvertently marginalized individuals who do not have clinical backgrounds. In addition, some participants felt that the use of the term “Projects” created a negative connotation for the required quality improvement project on each unit and instead preferred the terms “micro-project,” “safety strategy,” or “quick wins.”Implemented changes: The program’s name has been rebranded to NCPS Team Training, taking the word clinical out to be more inclusive of all team members who engage in the care of a patient in the clinical setting. A complimentary video series was developed for facility Master Trainers to use as a supplement to their teaching or exclusively as the teaching tool as they facilitate the tabletop simulation exercises. Another change is that the Unit Based Safety Project has been renamed as Unit Based Safety Initiative (UBSI) to remove the stigma of a “project.”
Physeal Location on the Distal Femoral Cortical Surface Is Consistently Proximal to Apparent Location on the Perfect Lateral Radiograph: A 3-Dimensional Digitally Reconstructed Radiograph Study
Authors: Rosenthal Reece M. , Froerer Devin L. , Metz Allan K. , Khalil Ameen Z. , Featherall Joseph , Maak Travis G. , Ernat Justin J. , Aoki Stephen K.
Published: May 2024

Introduction:

The perfect knee lateral radiograph visualizes anatomic landmarks on the distal femur for clinical and scientific purposes. However, radiographic imaging is a two-dimensional (2D) representation of a three-dimensional (3D) physis. The aim of this study was to characterize the perceived radiographic projection of the femoral physis using perfect lateral digitally reconstructed radiographs (DRRs) and to evaluate discrepancies from this projection to the physis at the lateral and medial cortices.

Methods:

Pediatric patients from a cohort of CT scans were analyzed. Inclusion criteria were an open physis; exclusion criteria were any implant or pathology affecting the physis. CT scans were imported into 3D imaging software and transformed into lateral DRRs and 3D renderings of the femur. The physis was divided into four equal segments, with fiducial markers placed at the “anterior,” “midpoint,” and “posterior” points. Lines extended from these points in the lateral and medial direction. The vertical distance from these lines, representing the radiographic projection of the physis, was measured relative to the physis at the lateral and medial cortex of the femur on coronal CT slices.

Results:

Thirty-one patients were included. On the perfect lateral radiograph DRR, the physis on the medial cortex was located proximal to the visualized physis by 6.64 ± 1.74 mm, 11.95 ± 1.67 mm, and 14.30 ± 1.75 mm at the anterior (25%), midpoint (50%), and posterior (75%) locations, respectively. On the lateral side, the physis on the lateral cortex was proximal to the visualized physis by 2.19 ± 1.13 mm, 3.71 ± 1.19 mm, and 6.74 ± 1.25 mm at the anterior, midpoint, and posterior locations, respectively.

Discussion:

In this cohort of pediatric patients, the location of the cortical physis was, in all areas measured, proximal to the projection of the visualized physis as seen on the perfect knee lateral DRR. The distance from radiographic physis to cortical physis was greater at the medial cortex compared with the lateral cortex.

Study design:

Descriptive laboratory study.

Level of evidence:

III, observational radiographic anatomic study.
Increasing Use of Promotional Language in Orthopaedic Surgery Abstracts—An Analysis of 112,916 Abstracts 1985 to 2020
Authors: Halvorson Ryan T. , Wong Liam H. , Feeley Brian T.
Published: May 2024

Background:

Increasing use of “hype” language (eg, language overstating research impact) has been documented in the scientific community. Evaluating language in abstracts is important because readers may use abstracts to extrapolate findings to entire publications. Our purpose was to assess the frequency of hype language within orthopaedic surgery.

Methods:

One hundred thirty-nine hype adjectives were previously identified using a linguistics approach. All publicly available abstracts from 18 orthopaedic surgery journals between 1985 and 2020 were obtained, and hype adjectives were tabulated. Change in frequency of these adjectives was calculated.

Results:

A total of 112,916 abstracts were identified. 67.0% (948/1414) of abstracts in 1985 contained hype adjectives, compared with 92.5% (5287/5714) in 2020. The average number of hype adjectives per abstract increased by 136% (1.1 to 2.6). Of the 139 adjectives, 87 (62.5%) increased in frequency and 40 (28.7%) decreased in frequency while 12 (9%) were not used. The hype adjectives with the largest absolute increases in frequency were quality (+324wpm), significant (+320wpm), systematic (+246wpm), top (+239wpm), and international (+201wpm). The five hype adjectives with the largest relative increases in frequency were novel (+10500%), international (+2850%), urgent (+2600%), robust (+2300%), and emerging (+1400%).

Conclusion:

Promotional language is increasing in orthopaedic surgery abstracts. Authors, editors, and reviewers should seek to minimize the usage of nonobjective language.

Authors: Singh Aaron , Kotzur Travis , Torres-Izquierdo Beltran , Momtaz David , Gonuguntla Rishi , Hoveidaei Amir Human , Seifi Ali , Galán-Olleros María , Hosseinzadeh Pooya
Published: May 2024

Purpose:

Slipped capital femoral epiphysis (SCFE) is a prevalent pediatric hip disorder linked to severe complications, with childhood obesity as a crucial risk factor. Despite the rising obesity rates, contemporary data on SCFE's epidemiology remain scarce in the United States. This study examined SCFE incidence trends and demographic risk factors in the United States over a decade.

Methods:

A decade-long (2011 to 2020) retrospective cohort study was undertaken using the Healthcare Cost and Utilization Project National Inpatient Sample. Patients aged younger than 18 years were identified and further analyzed if diagnosed with SCFE through ICD-9 or ICD-10 codes. Key metrics included demographics variables, with multivariate regression assessing demographic factors tied to SCFE, and yearly incidence calculated.

Results:

Of 33,180,028 pediatric patients, 11,738 (0.04%) were diagnosed with SCFE. The incidence escalated from 2.46 to 5.96 per 10,000 children, from 2011 to 2020, mirroring childhood obesity trends. Lower socioeconomic status children were predominantly affected. Multivariate analysis revealed reduced SCFE risk in female patients, while Black and Hispanic ethnicities, alongside the Western geographic location, had an increased risk.

Conclusion:

This study underscores a twofold increase in SCFE incidence over the past decade, aligning with childhood obesity upsurge. Moreover, SCFE disproportionately affects lower SES children, with male sex, Black and Hispanic ethnicities amplifying the risk. This calls for targeted interventions to mitigate SCFE's effect, especially amidst the vulnerable populations.

Este estudo revisa a literatura pertinente, abrangendo nove publicações de 2016 a 2023, encontradas nas bases SCIELO, LILACS, BDENF e PUBMED. A análise revela que a laserterapia, além de ser uma intervenção não invasiva e indolor, promove melhoras significativas na cicatrização, diminuindo desconfortos e acelerando processos inflamatórios. A atuação do enfermeiro é crucial nesse contexto, já que ele assume a responsabilidade desde a escolha do tratamento até a execução das etapas de cuidado. Os resultados apontam para uma melhoria na qualidade da assistência prestada, com a redução do tamanho da ferida e otimização do tempo de cicatrização. Entretanto, é enfatizada a necessidade de um profundo entendimento dos mecanismos da laserterapia para garantir seu sucesso terapêutico. Este estudo reforça a eficácia da laserterapia como uma ferramenta adjunta valiosa no arsenal terapêutico do enfermeiro no tratamento de feridas nos estágios I e II.

Comparison Between European Mystics in the 14th Century and Sumatran Sufis in the 16th-17th Centuries
Authors: Metzger Laurent
Published: May 2024

This study offers a comparative examination of the mysticism practiced by European spiritual thinkers in the 14th century and Sumatran Sufis in the 16th to 17th centuries, revealing striking inter-cultural similarities in their spiritual quests secluded from the urban tumult. These mystics, though divided by geographic and temporal distances, engaged profoundly with religious metaphysics, passionately expressing their spiritual explorations through sermons, literary compositions, and poetry. Central to their discourse was the relationship between the individual and the divine, with a particular focus on the soul’s crucial role in seeking spiritual fulfillment. The investigation highlights how these mystics from both the East and West tackled similar existential queries and embraced comparable methods of religious contemplation, which reflects a universal quest for understanding the divine essence. Recurring themes include the nature of divine love, the pursuit of spiritual authenticity, and the soul’s transcendental experiences, underscoring a shared narrative across these diverse cultural backdrops. The narrative of Mansûr al-Hallâj, a Persian mystic executed for his beliefs, exemplifies the extreme consequences faced by such profound thinkers, illustrating how deep spiritual commitment could lead to both profound admiration and severe persecution. Moreover, this analysis considers how these mystics were received within their societies—some were hailed as pioneers of thought, while others were condemned and executed as heretics by prevailing religious authorities. This contrast provides deeper insight into the complex dynamics between individual mystics and the broader societal and religious structures that either embraced or rejected their unconventional ideas. By providing a detailed comparative analysis, the study aims to enrich our understanding of mysticism as a bridge linking personal religious experience with the wider theological debates of the times. It contributes to a greater appreciation of the role of mystics in shaping religious thought across different historical and cultural contexts. This enriched narrative not only deepens our historical understanding of mystical traditions but also highlights the enduring dialogue between personal spiritual journeys and established religious doctrines.
