Organizational and legal principles of the activity of the prosecutor in combating crimes related to arson of military vehicles

The article is devoted to the disclosure of the organizational and legal principles of the prosecutor’s activity in combating crimes related to arson of military vehicles. In connection with the need to disclose the purpose of this scientific work, it is proposed to consider the specifics of the criminal-legal qualification of such acts, to determine the algorithm of organization of the prosecutor’s procedural management of the pretrial investigation of crimes of this category, and to provide practical advice on countering such a criminal-legal phenomenon. Considerable attention was paid to the analysis and generalization of studied real criminal proceedings about crimes of this category, which made it possible to identify the main problematic issues of prosecutorial and investigative activity in this area, including: the issue of primary qualification, the definition of the pretrial investigation body, the tactics and methods of organizing pretrial procedural management by the prosecutor investigation. On specific examples, attention is focused on the need to carefully study the subjective side of related, in this case, crimes that involve criminal liability for the intentional destruction (damage) of someone else’s property (in the context of this article – a military vehicle), committed by arson, as well as obstructing the legal activities of the Armed Forces of Ukraine. Certain methodical recommendations are given in this regard. In addition to suggestions for improving the prosecutor’s criminal and criminal-procedural activities, an effective algorithm of organizational and coordination measures of the prosecutor’s office to combat crimes related to arson of military vehicles was proposed in this direction. In particular, the creation of interdepartmental working groups with the involvement of representatives of law enforcement agencies (prosecutors’ offices, the National Police, the Security Service of Ukraine, the Military Law and Order Service), as well as state executive and local self-government bodies. The essence, purpose, forms and methods of their activity are disclosed.

Wearing Hearing Protection Makes Me Worse at My Job: Impacts of Hearing Protection Use on Sensorimotor Tracking Performance.

Occupational hearing loss is a significant problem worldwide despite the fact that it can be mitigated by the wearing of hearing protection devices (HPDs). When surveyed, workers frequently report that worsened work performance while wearing HPDs is one reason why they choose not to wear them. However, there have been few studies to supplement these subjective reports with objective measures. Where they do exist, assessed performance measures have mostly characterized auditory situational awareness in gross terms (e.g., average speech comprehension scores over an entire session). The temporal dynamics of performance and HPD impacts on nonauditory aspects of work performance are largely unknown. In the present study, we aimed to fill this gap in the literature by measuring how HPD usage impacted sensorimotor tracking performance in relation to ongoing auditory events. In two experiments, listeners heard commands sourced from the coordinate response measure (CRM) corpus (i.e., sentences of the form "Ready <call sign> go to <color> <number> now"). These commands informed listeners of which of nine moving on-screen objects to track with a computer mouse (e.g., "blue four" refers the listener to a blue square). The commands were presented in background street noise and were heard under either "No HPD" or "HPD" conditions. In experiment 1, HPD wearing was simulated with a digital filter designed to mimic the attenuation profile of a passive HPD. In experiment 2, actual HPDs were worn by listeners. Continuous recording of tracking error allowed us to simultaneously examine how HPD wearing impacted speech comprehension, the accuracy of tracking, and how tracking accuracy varied as a function of time on task and ongoing auditory events (e.g., the presentation of a critical CRM sentence). In both experiments, listeners spent less time tracking the correct object in the HPD condition. After trimming data to those time points in which the target object was known, worse performance was exhibited by the HPD condition than the No HPD condition. In the examination of the temporal dynamics of tracking error, it was apparent that differences arose strongly during the presentation of CRM sentences. Workers' complaints of poorer performance while wearing HPDs are justified and extend beyond just diminished auditory situational awareness. The negative impact on nonauditory aspects of work performance may be strongest around critical listening periods. Addressing these aspects of performance will be an important part of addressing HPD nonuse in occupational settings.

Changes in physical impairments in femoroacetabular impingement syndrome following arthroscopic surgery: a systematic review and meta-analysis

Abstract Femoroacetabular impingement syndrome (FAIS) is a motion-related condition causing hip pain in young active adults. Physical impairment measures of body function include objective and reproducible measures of hip mobility, muscle power, and movement coordination. Limited data on physical impairments and the effects of arthroscopic surgery exist. The aim of this systematic review was to investigate changes in physical impairments in those with FAIS, pre- and post-arthroscopic surgery. Six databases were searched for English-language studies reporting on pre- and postoperative physical impairments using physical outcome measures. Reporting quality was assessed using the Grading of Recommendations Assessment, Development and Evaluations (GRADE) framework, the Cochrane Risk of Bias tools and Methodological Index for Non-Randomized Studies (MINORS); for pooled data [standardized mean difference (SMD), and 95% confidence intervals (CI)]. Seventeen studies were included (two randomized controlled trials; fifteen pre/postintervention studies), varying from low-critical risk of bias, low-moderate on the MINORS, and very low reporting quality using the GRADE tool. Postoperatively, participants with FAIS walked with a higher peak hip flexion moment [SMD 0.5, 95% CI (0.12–0.88); heterogeneity I2 = 0%, P = .82] and reduced external rotation range [SMD −0.68, 95% CI (−1.34 to −0.01); heterogeneity I2 = 61%, P = .05]. Surgery increased participant hip flexion moment and impulse, hip strength and faster gluteus maximus contraction time. Patients demonstrated reduced hip extension, abduction and adduction angles during walking gait, and peak hip extension moments during gait and squatting. While this review found some physical impairments changed postoperatively, further research into specific subgroups of FAIS would enhance understanding and inform rehabilitation programs and optimize patient outcomes. Level of Evidence: IV (systematic review of III and IV evidence).

Statystical Analysis in Integration of Thermal Imaging and GNSS Satellite Measurements in Relation to Geological Structure as a Method to Improve the Accuracy of Displacement Determination of Engineering Structures

Numerous publications have confirmed the important contribution of applying GNSS satellite measurements in geologically unstable areas to the displacement measurements of engineering objects. Along with linking GNSS measurements of benchmarks considered to be stable in the long term to the nearest reference stations at appropriate measurement intervals. So, it was possible to improve the accuracy of measurements of vertical and horizontal coordinates in the area of Szczecin, ushering in coordinate errors of less than 2 and 5 mm. For objects of strategic use such as natural gas tanks located in salt formations, however, these values are too high. The displacement of salt formations is 0.5 mm per year. Therefore, I decided to review existing measurement methods in two areas with different geological structures - Szczecin and Wroclaw NW and SW Poland - as numerous spectrums of SAR methods. As a different method, I present the advantages of the radiometric method with the prospect of performing surveys in the abovementioned areas. The publication focuses on statistical analyses, and GNSS and radiometric field measurements are in progress.

Effect of Fused Filament Fabrication Parameters on Selected Indicators for Assessing Technological Quality of Shaped Models

Despite many studies, implementation of the additive manufacturing process in industrial and research practice is limited due to the numerous distortions affecting the obtained dependencies to a degree that is difficult to predict. No uniform methodology has been developed for the study of the impact of changes in the FFF parameters on the technological quality indicators. This paper presents a description of the original procedure for assessing technological quality using a reference component. The aim of the research was to analyze the impact of changes in the FFF additive manufacturing parameters on selected indicators of technological quality assessment of products. To compare the technological quality of the various models produced, measurements of surface roughness as well as dimensional and shape accuracy were carried out using stylus profilometry and coordinate measurement. The conducted tests showed that samples with a layer height of 0.12 mm have the most advantageous surface roughness parameters compared to the other layer heights of 0.16 mm and 0.20 mm tested. All the samples obtained were characterized by smaller dimensions than nominal, indicating the material shrinkage occurring during the FFF process. The study showed a negligible effect of material fill rate on surface roughness parameters as well as on the dimensions and shape accuracy. The obtained measurement results allow determining the most advantageous parameters of the FFF process depending on the adopted quality requirements.

Characteristics of patients diagnosed with psychogenic non-epileptic seizures (PNES) who request reinstatement of their driving privileges.

Patients who experience seizures, including PNES, are usually advised to discontinue driving, or have their driving privileges revoked until a determined period of seizure-freedom is achieved. In this retrospective study, patients with PNES who requested driving privileges or reported having resumed driving were compared to those who did not on measures of depression, anxiety, PTSD, and cognitive flexibility/motor speed. DiagnosisofPNESwasconfirmedwithvideo-EEG.Demographicand clinical dataand requests for reinstatement of driving privileges (requiring 6 or more months seizure freedom) and reports of decisions to resume driving were noted. Tests of motor speed and hand eye coordination and self-report questionnaires of depression, anxiety and PTSD administered as part of neuropsychological assessment were analyzed. A total of 403 patients with PNES evaluated in 2010-2020 were identified. Of those, 365 patients were eligible for inclusion, and of those, 60 applied for driving privileges or reported that they resumed driving. When the two groups were compared, the group that applied for driving privileges or decided to resume driving was significantly less depressed (p=0.001) when tested than the group that did not. Furthermore, a significant difference was seen in measures of motor performance between those who requested to resume driving and those who did not (DKEFS T1, p=0.006, DKEFS T2, p=0.001, DKEFS T3, p=0.002, DKEFS T4, p=0.001; GPT dominant, p=0.05, GPT non-dominant, p=0.003). Driving a motor vehicle is a useful measure of improvement for PNES because patients with seizures are required to discontinue driving until seizure-freedom is achieved. This study revealed that lower levels of depression and better fine motor functioning were associated with reported seizure-freedom and driving resumption. Depression is commonly associated with diminished performance (slower motor response times and impaired fine motor movements) on tests of motor functioning, both of which may result in less interest in pursuing permission to resume driving. These findings suggest that mood symptoms (and associated performance on measures of motor speed and coordination) may have prognostic significance in patients diagnosed with PNES. This also suggests that timely treatment of depression in newly diagnosed patients with PNES may be indicated.

Comparative Evaluation of the Dimensional Accuracy of Silicone-Based Putty Reline Impressions with Different Spacer Acquisition Techniques in Fixed Partial Dentures.

BACKGROUND A tooth preparation's clinical requirements and geometric configurations should take precedence over material characteristics when advocating for putty reline impression techniques for permanent restorations, since they require a technically sensitive spacer for light body elastomer. We evaluated the linear dimensional accuracy of vinyl polysiloxane-based putty reline impressions with different spacer acquisition techniques in short-span and long-span fixed partial dentures (FPD). MATERIAL AND METHODS A typodont tooth set simulated a 3-unit (short-span) and a 5-unit (long-span) FPD. Between respective prepared abutments, 31 coordinates were identified and measured based on angles (line/point) and surfaces (curved/flat). Sixty impressions (dual stage 2-step putty reline technique) were divided into 5 groups (n=12/group): group PP (pre-preparation putty), group GP (gouging putty), group PS (polythene spacer), group CT (conventional temporary), and group MT (modified temporary), depending on spacer acquisition method. Coordinates measurements were conducted using a measuring microscope. Descriptive and inferential statistical tests (ANOVA, post hoc Tukey) determined between-group and within-group differences, at P≤0.05 significance level. RESULTS In short-span FPD, compared with control, the number of significantly different coordinates group-wise were GP (4 coordinates), PP (2 coordinates), and PS, CT, and MT (1 each). In long-span FPD, compared with control, the number of significantly different coordinates group-wise were group GP (12 coordinates), group PP (10 coordinates), group PS (5 coordinates), and group CT and group MT (4 each). CONCLUSIONS Different spacer acquisition methods produce varied thickness of spacers for relining of putty. CT and MT, when used as spacers, provided maximum accurate coordinates for angles (line/point) and surfaces (curved/flat).

Exposure or age? The effect of additional CLIL instruction on young learners’ grammatical complexity while performing an oral task

The purported foreign language gains of content and language integrated learning (CLIL) over traditional EFL (English as a foreign language) programs with young learners are still unclear. Specifically, little is known about how CLIL time and timing impact grammatical complexity. Additionally, mediating factors such as socioeconomic status (SES) and extramural exposure have been rarely controlled in the existing literature. This study analysed grammatical complexity in four groups of young learners in Spain ( n = 108) during an oral task. The sample comprised: (1) an EFL-only group (1,766 EFL hours), (2) a low-exposure CLIL group (1,766 EFL hours + 707 CLIL hours), (3) a high-exposure CLIL group (1,766 EFL hours + 2,473 CLIL hours), and (4) a younger high-exposure CLIL group (1,545 EFL hours + 2,164 CLIL hours). All groups were matched for SES and extramural exposure. The analysis included independent ratings and computational measures of overall sentence complexity, subordination, and coordination. Distribution, Kruskal–Wallis and post-hoc tests were conducted. Results showed significant differences in favour of the high-exposure groups over the EFL-only group in the ratings and in two of the computational measures: overall sentence complexity and subordination. This evidence highlights the potential of high-exposure CLIL to supplement grammatical instruction in EFL programs. Our results also suggest that the comparatively higher exposure of the younger high-exposure CLIL group has the potential to override the one-year cognitive advantage of the older, EFL-only learners.

Correction of systematic image misalignment in direct georeferencing of UAV multispectral imagery

ABSTRACT Mosaicking of Unmanned Aerial Vehicles (UAV) imagery over featureless water bodies has been known to be challenging, and poses a significant impediment to water monitoring applications. Techniques such as Structure-from-motion typically fail under such conditions due to the lack of distinctive features in the scene, and direct georeferencing is currently the only practical solution, albeit lower georeferencing accuracy is expected. However, hardware issues, particularly the typical time delay between the GPS unit and the image capture, can lead to systematic image misalignment and further reducing the accuracy. The systematic image misalignment arises as the recording of the geographical coordinates by the GPS unit may not precisely correspond to the exact moment of image exposure, and the image exposure may not always occur at the mid-exposure time. Hardware solutions can mitigate this issue but require technical expertise and resources. Alternatively, software solutions can address the problem without necessitating any hardware modifications. This study introduces an open-source solution for the correction of the systematic image alignment by accounting for the time delay and distance discrepancy between the measurements of the GPS coordinates and the image capture. The method was validated with field UAV surveys conducted in this study under various flight configurations (different flight altitudes and overlap ratios), and effective image alignment was obtained using the proposed open-source solution which reduced the georeferencing error by around 67.7%. Specifically, a georeferencing error of RMSE = 1.409 m and σ = 0.6356 m was achieved without the use of any ground control points (GCPs). Finally, as demonstrated in this study, low flight altitudes (e.g. 15 m) should be discouraged for such conditions as georeferencing errors could amplify due to the limited accuracy of the GPS, resulting in visual artefacts.

Improving the accuracy of a platformless inertial navigation system for an aircraft during rapid roll rotation

The article addresses the problem of enhancing the accuracy of an autonomous strapdown inertial navigation system (SINS) for aircraft with rapid rotation about their longitudinal axis. This rapid rotation stabilizes the aircraft's position along the longitudinal axis while imposing strict requirements on the roll gyroscope's scale factor (SF) error in the SINS. This is essential to ensure that the roll angle error remains on par with the pitch and yaw angle errors. A novel method for periodic correction of the roll gyroscope's SF within an autonomous SINS is proposed. The method utilizes signals from a single-axis indicator gyrostabilizer based on a microelectromechanical system (MEMS) gyroscope. The correction involves determining the numerical value of the roll gyroscope's SF error during flight and subsequently compensating for its influence on the roll angular velocity measurements. The functional scheme of the method is presented, along with formulas for calculating the correction coefficient. The efficiency of the proposed approach in improving the accuracy of the SINS is evaluated using a typical inertial module and an indicator gyrostabilizer with a MEMS gyroscope as an example. The method significantly enhances the accuracy of roll angular velocity and coordinate measurements in an autonomous SINS without requiring expensive precision gyroscopes.

Coordination activities in the field of anti-crime as a function of a state authority

The scientific publication examines the issue of the expediency of consolidating the crime prevention coordination function under the prosecutor’s office or another state body, in particular the Ministry of Internal Affairs of Ukraine or the police. It is noted that in the conditions of negative trends towards the growth of the level of crime, strict regulation and delimitation of the responsibility of law enforcement agencies and the concentration of their efforts on countering armed aggression, the coordination of work to prevent, detect and counter criminal offenses is of particular importance. The article focuses on the fact that today this function is assigned to the prosecutor’s office, but its current legislative regulation is not perfect. As a result, there are opposing opinions regarding the expediency of consolidating the coordination of countering crime by the prosecutor’s office. This is due to the fact that, since 2014, the issue of the role and place of the prosecutor’s office in the system of state authorities has not been finally resolved. Analyzing the norms of the legislation, it is concluded that the coordination activity of the prosecutor’s office can be considered as a separate function of the prosecutor’s office, which, however, is related to the organization of the pre-trial investigation in the broad context of this meaning. It is emphasized that when determining the body that should be entrusted with the main consolidating role, the principle of equality of subjects of coordination activity should be maintained. It is justified why not only law enforcement, but also other state bodies should be included in the subjects of crime prevention coordination. It was concluded that in order to play a key consolidating role in coordination activities in this area, the state body must meet the following requirements: 1) be permanently active; 2) to carry out law enforcement activities in this area; 3) have an extensive system covering all levels; 4) to be an equal participant in legal relations alongside with other subjects of coordination activity; 5) be authorized to counter crime in all spheres, regardless of jurisdiction; 6) have sufficient authority to ensure control over the implementation of coordination measures. Therefore, at present, there is no other alternative, according to which the coordination activity in countering crime could be transferred to another body than the prosecutor’s office. However, other state bodies, or special bodies formed under them, including those under the Ministry of Internal Affairs of Ukraine, may perform auxiliary, consultative, and advisory functions in the field of crime prevention coordination, which, however, cannot replace the overall key coordinating role of the prosecutor’s office.

Method of determining the coordinates of a low altitude object under the conditions of using several radio signals.

Currently, in large cities, there is a steady tendency to increase the spatial density of telecommunication systems. The saturation of the radio spectrum with analog and digital systems used to solve the problems of radio communication and television allows to improve the technologies of semi-active radar detection and determination of the coordinates of a low-altitude object on their basis. Conducting radar surveillance using non-radar radar transmitters is often called semi-active radar using extraneous or parasitic radiation sources. The advantages of such systems are the minimization of deployment costs, low operating energy costs, low probability of malfunctioning, stealth of the fact of operation, environmental friendliness, and the absence of requirements for the allocation of radio frequency resources. Relatively high heights of antennas of communications and television transmitters with the existing radiated power create favorable conditions for detecting low-altitude objects. Digital signals of modern telecommunication systems have a spectrum width that provides acceptable resolution and accuracy of measuring the total distance and angular coordinates [20; 21]. In the general case, systems of this type are a multi-position system consisting of one or more radiation sources and one or more receiving positions spread in space [22; 23]. The paper gives a general description of the proposed method of determining the coordinates of an aerial object at low altitude under the conditions of propagation of several beams of radio signals. The method and its technical solution capable of determining the coordinates of an unauthorized low-altitude object under the conditions of the existence of several rays of radio signal propagation are defined, and the algorithm of its operation necessary for the technical implementation of the proposed method is presented. The paper considers options for determining the coordinates of aerial objects with different composition of primary coordinate measurements and the number of receiving points. The accuracy of determining the location of the object for multi-position radio systems of this type was evaluated under the conditions of the existence of several beams of radio signal propagation in the developed model, taking into account the number of received signals and their measurement errors.

Coupling coordination measurement and spatiotemporal evolution characteristics of digital economy, environmental regulation, and carbon emission intensity—Empirical evidence from Chinese provinces

Digital economy, as an innovative digital technology, can promote environmental governance and support low-carbon development. Under the backdrop of China's dual carbon strategy, the country faces significant challenges in achieving coordinated development across the domains of economy, environment, and energy. Based on panel data from 30 Chinese provinces between 2012 and 2022, this paper constructs a coupling coordination model to measure the level of integrated development among digital economy, environmental regulation, and carbon emission intensity. The study also examines the spatiotemporal evolution of this coordination using kernel density estimation and spatial correlation tests. Furthermore, empirical analysis via regression models was employed to investigate key influencing factors. The findings suggest that: (1) The coupling coordination level has shown an upward trend over the sample period, with no extreme regional disparities; (2) Spatially, the development of coupling coordination exhibits “high-high” and “low-low” clustering effects; (3) Development levels are influenced by various external driving factors, with significant regional differences in primary influencing factors. For these findings, the following recommendations are proposed: enhance digital infrastructure, optimize regulatory frameworks, and promote the integration of digital economy with green and low-carbon development.

Development of a Deployable Reflector Antenna for the Synthetic Aperture Radar Satellite, Part 2: Manufacturing and Qualification of the Main Reflector Using a Honeycomb Sandwich Composite Structure

A deployable reflector antenna (DR-A) is a structure that can be stored in a large-diameter Synthetic Aperture Radar (SAR) antenna and be mounted onto a launch vehicle. Considering the performance of the launch vehicle, it is necessary to develop a lightweight, high-performance antenna structure. The solid-type deployable reflector antenna is composed of a number of unit main reflectors. To reduce the weight of the antenna, a lightweight main reflector must be developed. In this paper, following “Development of Deployable Reflector Antenna for the SAR Satellite (Part 1)”, the manufacturing and qualification of the main reflector using honeycomb sandwich composites are described. Four types of composite main reflectors were manufactured with variables in the manufacturing process. The manufacturing variables include the curing process of the structure, the application of an adhesive film between the sheet and the core, and the venting path inside of the sandwich core. After manufacturing the main reflector, we performed weight measurements, non-destructive testing (NDT), surface error measurement using a Coordinate Measurement Machine (CMM), and modal testing for each type of composite main reflector. Through the research and development process, we found that a perforated hole is necessary when excluding the adhesive film during bonding of an aramid core and a CFRP sheet, and a lightweight composite reflector could be developed through this process. We selected the main reflector with the best performance and developed a composite main reflector that can be applied to satellites.

Associations Between Oncology Outreach and Patient-Sharing Measures of Care Coordination.

Oncology outreach is a common strategy for addressing cancer workforce shortages, where traveling oncologists commute across clinical settings to extend their services. Despite its known benefits specifically for rural patients, oncology outreach reallocates physician resources to satellite clinics and may negatively impact the coordination of cancer care. In this retrospective study, we identified patients with incident breast, colorectal, and lung cancers from 2016-2019 nationwide Medicare claims and linked them to oncologists using Part B. We considered encounters occurring outside the physician's primary hospital service area as "outreach visits" and calculated the proportion of outreach visits by oncology specialty for contiguous US hospital referral regions (HRRs) using 2016-2017 claims. We constructed a nationwide physician patient-sharing network from 2018-2019 claims and computed median care density-a measure of physician team familiarity-and local transitivity-a measure of physician cohesion/clustering-for each HRR as proxies for care coordination. Generalized linear models were used to explore the associations between oncology outreach and care coordination measures at the HRR level. We found that HRRs with high medical oncology outreach were associated with 16% decreases in care density (95% CI: 5-25) and 4% decreases in local transitivity (95% CI: 1-8) compared to HRRs with low medical oncology outreach. HRRs with high radiation and surgical oncology outreach were not associated with network-based measures of care coordination. While medical oncology outreach increases access for underserved patient populations, it potentially fragments care delivery across clinical settings. Health systems may consider this trade-off to inform decisions concerning the implementation of outreach programs or policies aimed at hedging against fragmentation in markets with active outreach arrangements.

Comparative Analysis of Aluminium 6061-T6 With Different Stock Leaves Setting on Holes True Position: A Case Study

With the evolution of industrial technology, improved machining processes have been developed. With the expansion of machining processes, machining characteristics alter according to the tool and work materials, tools used, machining technique used, etc., increasing surface smoothness, dimensional accuracy, and tool wear. Geometric error is a problem in precision machining due to parameter settings. This research aims to analyse the effect of stock leave setup on achieving precise product hole positions and improving machining process efficiency. The substrate involved was AL6061-T6. This study involved the use of MasterCAM software for simulation analysis to predict the effectiveness of the machining process. Then, the machining process was implemented with different stock leaves of 4 mm and 1 mm using a 5-axis Mazak machine. The result reveals the coordinate measurement machine (CMM) reading is proportional to the stock leave setup. The small reading value of CMM produces better accuracy cutting in machining process. In addition, a small value of stock leave produces a hole position within the specification due to adding additional processes compared to the high value of stock leave. Thus, with suitable parameters, all machining processes can produce a good accuracy of finishing parts and meet customer requirements.

Coordination Strategy for Achieving Community Social Infrastructure Development Goals in Bhola, Bangladesh

This paper aims at identifying the Prospects for Sustainability in Community Social Infrastructure Development having regard to Coordination Mechanisms and Stakeholders: A Case of Bhola Bangladesh. Employing a qualitative research approach, the paper seeks to establish the issues, approaches, and achievements towards owning coordination in rural setting. Interviews, focus group discussions and document review adopting both open ended questionnaires and interviews were conducted with 20 purposively selected participants drawn from different fields similar to previous study. Therefore, this study established that though there is improvement in coordination at the Bhola level, problems like resource constrains, lack of technical know-how and communication barriers are still some of the issues that hinder the functioning of agencies there. Improvement in the coordination measures entailed the maintenance of an open forum, trust amongst the stakeholders, and the adoption of the structure that captured the needs of the locals. Moreover, it was also found that for infrastructure projects to have sustainable outcomes, the community has to be involved actively in the projects. This paper adds to the studies on multi-stakeholder partnership in community advancement and offers ideas concerning the issues of advancing rural, Ashley positioned, limited asset areas. The study therefore can contribute to enhancing the coordination strategies in other contexts with the inference that equal blend of formal and informal coordination mechanism coupled with active community participation plays critical role to enhance the development of infrastructure projects.

Correlation analysis of failure risk factors in automated container port logistics systems from a resilience perspective

This paper aims to explore the correlations among failure risk factors of automated container port logistics systems from a resilience perspective. Based on the Wuli-Shili-Renli (WSR) theory and a multi-dimensional resilience framework, five key categories of risk factors affecting system resilience are identified: port infrastructure, port logistics operation organization, port personnel, port operational environment, and port emergency response and management. Through expert interviews, system component analysis, and a review of related literature across these five dimensions, 36 specific risk factors were identified to establish an initial set of system failure risk factors. Subsequently, a dual-factor screening method combining grey relational analysis and rank correlation was applied to simplify the initial set, constructing a system failure risk factor index system from a resilience perspective. Finally, a comprehensive model combining the Fuzzy Decision-Making Trial and Evaluation Laboratory (FDEMATEL) method and the Total Adversarial Interpretation Structure Model (TAISM) was proposed. This model identifies and quantifies the complex correlations among system failure risk factors from a resilience perspective, revealing their relative importance and their impact on system resilience. The results indicate that system resilience is primarily influenced by internal factors such as the smoothness of collection and distribution operations, infrastructure service capacity, and the stability of technical support systems. External factors, such as the prevention capability for major emergency threats and the improvement of government supervision and coordination feedback mechanisms, also significantly impact system resilience. The complex interactions among key factors have a profound effect on system resilience, underscoring the need to enhance coordination and management measures to strengthen overall system resilience. This study provides a theoretical foundation for developing targeted strategies to enhance the resilience of automated container port logistics systems.

Changes in lower extremity muscle coordination over a 30-minute walk do not differ by muscle fatigability

Muscle fatigue, the transient decrease in muscle power, leads to low levels of physical activity and an inability to perform activities of daily living. Altered muscle coordination in response to fatigue may contribute to impaired physical performance. We sought to determine whether lower extremity muscle coordination during gait changes differently depending on susceptibility to fatigue (i.e., fatigability). Thirty-one older adults completed muscle power testing before and after a 30-min walk, with the change in power used to categorize participants as more or less fatigable. We used non-negative matrix factorization to identify muscle modules from electromyography (EMG) from the 2nd minute as our measure of baseline muscle coordination. Changes in muscle coordination were determined by computing the variance in the 30th minute’s EMG accounted for by the baseline modules across all muscles (tVAF) and in individual muscles (mVAF). We compared tVAF between the 2nd and 30th minutes of the walk in individuals who were more and less fatigable. We used mVAF to explore the contribution of changes in individual muscle activity to tVAF. There was a decrease in tVAF overall in response to the walk (p < 0.001; 92.3 ± 1.6 % vs. 89.0 ± 4.3 %) but this did not differ between groups (interaction p = 0.66). There were significant associations between mVAF and tVAF for knee extensor, knee flexor, and ankle dorsiflexor muscles. Our results suggest that muscle coordination changes over the course of a walk in older adults but that this change does not differ between more and less fatigable older adults.

Captive swedes and the formation of mathematical cartography in Siberia (1711–1722)

After the defeat of Charles XII at Poltava, thousands of soldiers and officers of his army ended up in Russian captivity. Many of them were then exiled beyond the Urals, where they lived from 1711 to 1722. It is the Swedish officers that the beginnings of mathematical cartography of Siberia are associated with. The article analyzes the aspects of the work of the best known Swedish cartographer, Captain Philip Johan Tabbert (Philipp Johann von Strahlenberg) and provides information about other Swedes who engaged in cartography. At the early stage of the formation of mathematical cartography, an important problem was converting Russian linear measures into degrees. Various ratios used by both the Swedish captives and the Russian land surveyors are given. The methodology for longitude coordinates determination was studied based on the analysis of the maps and diary entries, made by Tabbert during D. G. Messerschmidt’s expedition. Indirect evidence of measurements of latitudinal coordinates, carried out by Swedish captives before the arrival of Russian surveyors in Siberia, has been collected. All of this enabled the analysis of mathematical basis of the two manuscript maps made by the Swedes in Siberia. It is concluded that the geographical maps, drawn in the Siberian captivity by Charles XII’s officers, continued the European tradition of mapping Siberia, being a separate stage in this process. What distinguished such maps was that their authors lived in the region they mapped. The Swedish captives became the first cartographers of Siberia, who created mathematically precise geographical maps with a grade grid, rather than hand-drawn, artistic maps. At the same time, Swedish officers’ efforts associated with creating geographical maps of Siberia had no impact on the development of Russian cartography. It was not the Swedes who broke the tradition of cartographic isography but, rather, the Russian graduates of the Maritime Academy who began working in Siberia in 1719.
