ANALYSIS OF CONFLICTS IN THE MEDICAL INDUSTRY: TODAY'S RELEVANCE

Given the extreme importance of medical care for public health, resolving conflict situations in medical institutions becomes an urgent need. An important component of the conflict management strategy in the medical field is not only the resolution of conflicts that have already arisen but also their anticipation and prevention. To achieve this goal, it is necessary to implement a system for early detection of conflicts, improve the communication skills of medical staff, as well as improve the system of personnel management and allocation of resources in medical institutions.The purpose of the research is to study the opinion of the heads of health care institutions of the Chernivtsi region regarding the frequency of conflicts in medical teams and the participation of the head in a conflict situation.Material and methods. With the use of statistical and medical-epidemiological methods, an analysis of anonymous questionnaires of 48 medical managers and 1146 patients was carried out in order to study the correlation relationship (Kramer coefficient) of conflict situations with the efficiency of the work of health care institutions.Results and discussion. It was established that conflicts periodically arise among medical workers, according to 47.2% - 60.6% of respondents of all age categories, and very often - according to 15.2% of people aged 36-55, 17.7% of responses of people 18- 35 years old and 22.85 people aged 56 years and older. Persons aged 36-55 years and 56 years and older take the most active part in the conflict (52.8-58.3% of responses), while persons aged 18-35 years are quite often passive observers (37.5%) and do not participate in conflicts (25.0%).The obtained results confirmed the need to develop and implement scientifically based preventive methods in order to improve the organization of the process of prevention and management of medical conflicts at the regional level, and their further implementation in the work of medical institutions.Conclusions. Therefore, in today's world, where attitudes towards medical care and demands for it are constantly growing, conflict resolution in medical institutions is an urgent need. The urgency of the problem of conflicts in the medical field must be understood and appropriate attention and resources must be given to it to ensure the effective functioning of medical institutions and high quality of medical care.

Hate Speech Propagation and Regulation in WhatsApp Groups: Evidence from Nigeria

ABSTRACT This study examines the prevalence and effects of hate speech propagation on WhatsApp groups in Nigeria. It also explores the role of WhatsApp group administrators (WGAs) in regulating it. Online passive participant observation method was used to collect data from sixteen purposively selected WhatsApp groups in Nigeria. Results indicate a high prevalence of gender, religious, political and ethnic hate speech in majority of the sampled WhatsApp groups. It also shows that hate speech generates tension and conflict among WhatsApp group participants. Moreover, the study reveals that most WGAs applied punitive measures against hate speech propagators. The findings advance the emerging area of online hate speech and brings to fore the conflict resolution, peacebuilding and third-party policing potentials of WhatsApp group administrators.

A Machine Learning Method to Retrieve Global Rainfall and Snowfall Rates From the Passive Microwave Observations of FY‐3E

AbstractPassive microwave radiometers onboard satellites rely on the received upwelling radiation to retrieve precipitation, which is a mixed signal from the surface, atmosphere and precipitation hydrometeors. Liquid precipitation droplets increase the upwelling radiation from the surface at lower frequencies, while ice particles cause a decrease in upwelling radiation at higher frequencies. The task of the retrieval algorithm is to identify the precipitation phase and to isolate the signal of precipitation from that of the surface. This study develops a machine learning method to retrieve rainfall and snowfall rates based on observations from the Microwave Hydrometer Sounder and Microwave Temperature Sounder onboard FY‐3E. Self‐organized mapping (SOM) is selected to classify the precipitation and underlying surface types, and an artificial neural network (ANN) is subsequently used to relate the brightness temperature to the precipitation rate for the clusters derived from the SOM. The half‐hour product of the Integrated Multi‐Satellite Retrieval for Global Precipitation Measurement (IMERG) is used to train the ANN. To address the issue that number of heavy precipitation samples are not enough for training, the simulation of radiative transfer for TOVS is used as a supplement to heavy rain samples. The SOM‐ANN algorithm outperforms the IMERG and Goddard profiling algorithm (GPROF) retrieval products in both rainfall and snowfall retrieval. Compared with the hourly observations at ∼4,400 stations during a 2‐year period, the root mean square errors of SOM‐ANN proposed here are 1.06 and 0.34 mm/hr for the rainfall and snowfall rates, which are better than those of IMERG (1.23 and 0.42 mm/hr) and GPROF (1.22 and 0.44 mm/hr).

Neural basis of lower-limb visual feedback therapy: an EEG study in healthy subjects

BackgroundVideo-feedback observational therapy (VOT) is an intensive rehabilitation technique based on movement repetition and visualization that has shown benefits for motor rehabilitation of the upper and lower limbs. Despite an increase in recent literature on the neurophysiological effects of VOT in the upper limb, there is little knowledge about the cortical effects of visual feedback therapies when applied to the lower limbs. The aim of our study was to better understand the neurophysiological effects of VOT. Thus, we identified and compared the EEG biomarkers of healthy subjects undergoing lower limb VOT during three tasks: passive observation, observation and motor imagery, observation and motor execution.MethodsWe recruited 38 healthy volunteers and monitored their EEG activity while they performed a right ankle dorsiflexion task in the VOT. Three graded motor tasks associated with action observation were tested: action observation alone (O), motor imagery with action observation (OI), and motor execution synchronized with action observation (OM). The alpha and beta event-related desynchronization (ERD) and event-related synchronization (or beta rebound, ERS) rhythms were used as biomarkers of cortical activation and compared between conditions with a permutation test. Changes in connectivity during the task were computed with phase locking value (PLV).ResultsDuring the task, in the alpha band, the ERD was comparable between O and OI activities across the precentral, central and parietal electrodes. OM involved the same regions but had greater ERD over the central electrodes. In the beta band, there was a gradation of ERD intensity in O, OI and OM over central electrodes. After the task, the ERS changes were weak during the O task but were strong during the OI and OM (Cz) tasks, with no differences between OI and OM.ConclusionAlpha band ERD results demonstrated the recruitment of mirror neurons during lower limb VOT due to visual feedback. Beta band ERD reflects strong recruitment of the sensorimotor cortex evoked by motor imagery and action execution. These results also emphasize the need for an active motor task, either motor imagery or motor execution task during VOT, to elicit a post-task ERS, which is absent during passive observation.Trial Registration NCT05743647

Polar Sea Ice Monitoring Using HY-2B Satellite Scatterometer and Scanning Microwave Radiometer Measurements

The Ku band microwave scatterometer (SCA) and scanning microwave radiometer (SMR) onboard HaiYang-2B (HY-2B) can simultaneously supply active and passive microwave observations over the polar region. In this paper, a polar ice water discrimination model and Arctic sea-ice-type classification model based on the support vector machine (SVM) method were established and used to produce a daily sea ice extent dataset from 2019 to 2021 with data from SCA and SMR. First, suitable scattering and radiation parameters are chosen as input data for the discriminant model. Then, the sea ice extent was obtained based on the monthly ice water discrimination model, and finally, the ice over the Arctic was classified into multiyear ice (MYI) and first-year ice (FYI). The 3-year ice extent and MYI extent products were consistent with the similar results of the National Snow and Ice Data Center (NSIDC) and Ocean and Sea Ice Satellite Application Facility (OSISAF). Using the OSISAF similar product as validation data, the overall accuracies (OAs) of ice/water discrimination and FYI/MYI discrimination are 99% and 97%, respectively. Compared with the high spatial resolution classification results of the Moderate Resolution Imaging Spectroradiometer (MODIS) and SAR, the OAs of ice/water discrimination and FYI/MYI discrimination are 96% and 86%, respectively. In conclusion, the SAC and SMR of HY-2B have been verified for monitoring polar sea ice, and the sea ice extent and sea-ice-type products are promising for integration into long-term sea ice records.

Robot remote control using virtual reality headset: studying sense of agency with subjective distance estimates

Mobile robots have many applications in the modern world. The autonomy of robots is increasing, but critical cases like search and rescue missions must involve the possibility of human intervention for ethical reasons and safety. To achieve effective human–robot interaction, the operator needs to have a sense of agency (SoA) over the activities of the robot. One possible way to increase one's SoA in remote control could be the use of VR technology. The remote control situation has some important features, so indicators of SoA need to be reproduced there independently. In our study, participants controlled a mobile robot using either a monitor or a VR-headset as an output device. In both cases, active control was contrasted with passive observation of the robot's movement. In each trial, participants estimated the distance traveled by the robot—a putative implicit indicator of SoA. A significant difference between subjective distance estimates was found in the active and passive conditions with the monitor, but not in the active and passive conditions with VR. The effect obtained in the monitor conditions suggests that distance estimates can be used as an implicit indicator of SoA in robot remote control. We believe that the lack of difference between the active and passive conditions in VR was caused by motion sickness due to a mismatch of visual and vestibular sensory cues, leading to a weakened SoA.

Webcam technology on neonatal wards—examining the objective and subjective workload of nurses: a combined observational and survey study

BackgroundThis study was conducted to estimate the additional objective and perceived workload of nurses resulting from the use of webcams. The successful implementation of webcam technology into routine care requires an analysis to prevent adverse events of increased nursing workload.MethodsThe study took place on three neonatal wards in two University Hospitals in Germany. In the first Hospital, the study was conducted from February to July 2021; in the second one it was conducted between June and November 2021. Data were collected using a combined approach of a standardised diary questionnaire study and passive observations. The participants were accompanied in their daily work and their activities were recorded 65 nurses participated.Results2,031 h were observed in 1,630 observation blocks. In 14.74% of the observation blocks webcam activities were detected. The extent to which the nurses had webcam-related additional workloads was rated as no additional workload in 82.16% of the daily questionnaires (n = 1,026).ConclusionThe observed low workload due to the webcams is in line with the nurses’ perception. The observational data revealed, on a number of different analysis levels, that a limited additional workload was generated. There was no decrease in activity performance observed and no clear indication for interruptions due to the webcam-related activities for the nurses. However, it is important to raise awareness about the individual workload levels for the successful implementation. Additional education programs can be provided for nurses.Trial registrationThe Neo-CamCare study is registered at the German Clinical Trials Register. DRKS-ID: DRKS00017755.

Ion- and surface-sensitive interactions during oxygen evolution reaction in alkaline media

Abstract Clean and sustainable energy has turned towards electrochemical water splitting as a viable solution in minimizing carbon emissions. Electrolysis of water converts electrical energy to chemical energy, through the production of hydrogen and oxygen gases, which can be harnessed for potential applications without contributing to greenhouse emissions. While this energy storage process shows great potential, its efficiency is hindered by the sluggish kinetics of the oxygen evolution reaction (OER). As a result, its widespread application in green electrolytic technologies is limited hence investigations on improving OER kinetics are of utmost importance. Recent research breakthroughs indicate that alkali metal cations are more than passive observers. They play complex roles in the electric double layer (EDL), which positively influences the OER kinetics. The presence of numerous ions and their combinations presents a challenge of complexity. This study aims to delve into the impact of alkali metal cations on OER activity due to the variance in their hydration energies. Specific investigations focusing on different alkali metal cations in solution, such as Li+, Na+, and K+, was conducted on RuO2 to gain a deeper understanding of how these ions interact with both reactants and intermediate species in the reaction kinetics. Traditional electrochemical tests, including cyclic voltammetry (CV), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and accelerated degradation test (ADT) measurements were employed to elucidate critical aspects such as surface activation, electric double layer interactions, catalytic activity and stability, ohmic resistance, and mass and charge transport.

Automatic detection and tracking polar lows from synthetic aperture radar and radiometer observations

ABSTRACT Polar lows are small, high-latitude, intense maritime cyclones and frequently have severe impacts on the ocean such as strong winds, high waves and heavy rainfall. They are difficult to observe and forecast due to their short lifetime (<48 hours), small horizontal scales (200 ~ 1000 km), and the sparse synoptic observing network that exists in the subarctic and Arctic oceans. Previous studies have identified and monitored polar lows by visual analysis of visible and thermal infrared imagery from satellites. However, this manual inspection method is subjective, time-consuming and inevitably involves errors in polar low detections. In this study, we present an automatic objective procedure which we demonstrate by detecting polar lows using spaceborne active synthetic aperture radar (SAR) and passive microwave radiometer observations. Based on the marker-controlled watershed segmentation method and the morphological image thinning algorithm, the centre locations of polar lows are determined using RADARSAT-2 and Sentinel-1A high-resolution SAR images and total atmospheric water vapour content fields from radiometers (AMSR2, SSM/I, GMI, and WindSat). Furthermore, the trajectories of polar lows are constructed, using detected centres from multi-temporal SAR and radiometer observations. Polar low detections are confirmed by high surface wind speeds from SAR, scatterometer, and radiometer data, the presence of cloud vortex signatures visible in MODIS, AVHRR, and VIIRS thermal infrared imagery, as well as the difference between the sea surface temperature and the air temperature at 500 hPa. These results show that the proposed methods have potential to automatically detect and track polar lows from multisensor data. We also estimate the characteristic parameters of detected polar lows. The diameters, translation speeds, and distances travelled are 189 km and 225 km, 8 m/s and 4.9 m/s, and 318 km and 263 km, respectively.

Seismic Node Arrays for Enhanced Understanding and Monitoring of Geothermal Systems

Abstract Harnessing geothermal energy will likely play a critical role in reducing global CO2 emissions. However, exploration, development, and monitoring of geothermal systems remain challenging. Here, we explore how recent low-cost seismic node instrumentation advances might enhance geothermal exploration and monitoring. We show the results from 450 nodes deployed at a geothermal prospect in Cornwall, United Kingdom. First, we demonstrate how the nodes can be used to monitor the spatiotemporal and size distribution of induced seismicity. Second, we use focal mechanisms, shear-wave source polarities, and anisotropy to indicate how the dense passive seismic observations might provide enhanced insight into the stress state of the geothermal systems. All the methods are fully automated, essential for processing the data from many receivers. In our example case study, we find that the injection-site fracture orientations significantly differ from that of the crust above and the regional stress state. These observations agree well with fracture orientations inferred from independent well-log data, exemplifying how the nodes can provide new insight for understanding the geothermal systems. Finally, we discuss the limitations of nodes and the role they might play in hybrid seismic monitoring going forward. Overall, our results emphasize the important role that low-cost, easy-to-deploy dense nodal arrays can play in geothermal exploration and operation.

This research aims to understand and analyze Mixue's customer decisions and satisfaction on the social media platform Instagram. It also seeks to identify the factors that influence purchase decisions and customer satisfaction regarding Mixue products. Additionally, the research aims to provide recommendations to the company on how to improve customer decisions and satisfaction. The study utilizes a qualitative research method with a netnography approach. Based on the findings of the research, two types of responses from the participants were observed: positive and negative responses. Positive responses indicate satisfaction with the decisions made, while negative responses reflect dissatisfaction with the decisions. There are several triggers for customer satisfaction and dissatisfaction, including price, product quality, and product halal status. One limitation of this research is the relatively small number of participants. For future research, it is recommended to involve more than seven participants to enable comparisons. Additionally, the study was limited by the data collection methods, which relied on passive observation and literature review. Future research could benefit from using in-depth interviews to obtain more profound insights.

Analysis of Bullying in Physical Education: Descriptive Study of Spanish Adolescents.

Physical education classes can be a place where both bullying and harassment take place, and a powerful strategy is needed to prevent it. The present study analyses bullying and students' behaviour as active or passive observers in a general educational context and physical education lessons. A sample of 958 adolescents aged 12 to 18 was studied. A questionnaire was used to analyse the victimisation and the bullying and behaviour observed. The results showed a lower incidence rate than that observed in other studies in physical education classes with a higher level of perpetration by boys than by girls and a more active rejection of aggression by victims and girls. On the other hand, passive attitudes were greater among perpetrators and boys. The observers' attitudes were similar in both contexts. The scenario in which this subject takes place could reduce the risk of these phenomena occurring. Therefore, physical education teachers should analyse these behaviours and intervene, especially when creating awareness in boys.

Application of Discovery Learning with Flashcard Media to Increase Active Mathematics Learning Madrasah Ibtidaiyah Students

This research aims to evaluate the mathematics learning process with a discovery learning model using flashcard media for class IV students at MI Al-Ma'arif 02 Jombang-Jember and identify their weaknesses and strengths. The approach used is descriptive qualitative with purposive techniques for determining subjects. Data was collected through passive participant observation, semi-structured interviews, and documentation, then analyzed using Miles and Huberman's interactive analysis model and tested for validity through triangulation of sources and techniques. The research results show that teachers prepare lesson plans, syllabi, media, and learning resources in planning learning. Implementing learning includes opening, core (with discovery learning syntax), and closing. Learning evaluation is carried out by assessing knowledge, attitudes, and skills. The advantages are that students become more active and enthusiastic, the material is easier for the teacher to convey, and it is easier for students to understand the material and work on questions. However, some students were less enthusiastic and needed help understanding the material, so they needed help answering the questions.

‘What’s he writing in there?’ Reciprocal field relations and relational curiosity in ethnographies of education

ABSTRACT The notion of the ethnographer as participant observer, as an active agent rather than passive observer, is well established within conversations about method and methodology. Less well explored is the extent to which the inherent curiosity and inquisitiveness of the ethnographer might be reciprocated: how might this be established and how might it contribute to the construction of knowledge? Through a focus on the ways in which one of the most visible aspects of ethnographic field work – writing field notes – was made sense of and then interrogated by research respondents during an eight-month ethnography of workplace learning, this article argues that reciprocal field relations characterised by a willingness for the researcher to be interrogated about their work in a manner akin to the ways in which the researched are, here described as relational curiosity, both sustains good ethical engagement in the field and enhances the empirical warrant of the ethnography.

This research aims to analyze the patterns of interpersonal communication in building an anti-corruption culture among customs officers' families in Medan City, analyze the forms of interpersonal communication messages conducted by customs officers' families, and analyze the barriers to interpersonal communication in building an anti-corruption culture among customs officers' families in Medan City. The theory utilized in this research is Joseph A. Devito's theory of interpersonal communication. The research method employed is qualitative research. The number of informants in this study is five customs officers, with criteria including being married, residing in Medan City, and receiving recognition as an Officer of the Month or Officer of the Year. Data collection is conducted through interviews and passive participation observation. The results of this study indicate that the pattern of interpersonal communication in building an anti-corruption culture among customs officers' families in Medan City is through the equality pattern of communication. Interpersonal communication messages used in building an anti-corruption culture among customs officers' families include informative and persuasive messages. The barriers to interpersonal communication in building an anti-corruption culture among customs officers' families include semantic and psychological noise. The married couples in this study agree that interpersonal communication within a family plays a crucial role in building an anti-corruption culture.

Attack detection method for encrypted wave‐variable‐based bilateral control systems

AbstractThis study presents an energy‐based attack detection method involving an encrypted bilateral control system using wave variables. In the considered bilateral control system, the leader and follower receive the follower's force information and the leader's velocity information, respectively, through the wave variables. The considered attack model multiplies the wave variables by an attack parameter, which is possible due to the malleability of the encryption scheme. The bilateral control system will be destabilized if the attacker chooses a relatively large parameter value. This motivates in developing a passivity observer for each leader and follower side to compute the total energy and constructing an energy‐based detection method that can be incorporated into the encrypted bilateral control system and is summarized in the presented theorem. Furthermore, this study provides a specific design for reasonable threshold parameters concerning the control system energy. The theorem and the experimental validation confirm that the developed encrypted wave‐variable‐based bilateral control system with the proposed attack detector is secure and effective as a countermeasure against malleability‐based attacks.

Efforts to Overcome the Moral Crisis among Children of Fishermen Families in Nibung Hangus District, Batu Bara Regency

This research examines various moral problems among teenagers in Ujung Kubu Village, Nibung Hangus Sub-district, Batu Bara Regency. This research aims to identify and analyze the factors that influence adolescents' moral behavior and the efforts made by fishermen's families to overcome these problems. A qualitative approach with a case study was used as the primary method. Data collection techniques included passive participatory observation, in-depth interviews with key informants, and document study. Data analysis was conducted using descriptive analysis techniques, narrative compilation, and verification through triangulation and member checks to ensure the accuracy and consistency of the findings. The research findings show that behavior against parents, abusive speech, fighting among friends, and often leaving the house in the middle of the night are serious moral problems among adolescents in this village. Factors influencing these problems include the role of parents, the influence of the peer environment, and the lack of consistent religious education. Parents face challenges in implementing moral education amid negative environmental influences. Family efforts include open communication, setting clear rules, and limiting the peer environment, although there are limitations in fully controlling children's behavior. This study reinforces previous theories about the importance of family and environment in adolescent moral formation and provides new insights into the complexity of moral issues in fishing communities. A more adaptive and responsive approach is needed to create an environment conducive to healthy and responsible adolescent development.
