Evaluating implementation of the EPIC peer bystander intervention program in basic law enforcement training (BLET)

ABSTRACT Mandated by a consent decree, the Ethical Policing is Courageous (EPIC) program was developed by the New Orleans Police Department (NOPD). The EPIC curriculum is based on active bystandership, encouraging officers to intervene when police misconduct could potentially occur. This research sought to evaluate the EPIC program recently adopted in one state. An adapted integrity measuring instrument from the National Institute of Justice (NIJ) developed by Klockars et al. was used to compare officers who have recently completed the ethics programming being phased out against officers who participated in the EPIC program. Results indicate a significant difference in the areas of reporting and intervening with respect to excessive force. Implications for further research are also provided.
Towards the Mechatronic Development of a New Upper-Limb Exoskeleton (SAMA)

Modern neuromuscular rehabilitation engineering and assistive technology research have been constantly developing in the last 20 years. The upper body exoskeleton is an example of an assistive rehabilitation device. However, in order to solve its technological problems, interdisciplinary research is still necessary. This paper presents a new three-degrees of freedom (DOF) active upper-body exoskeleton for medical rehabilitation named “SAMA”. Its mechanical structure is inspired by the geometry and biomechanics of the human body, particularly the ranges of motion (ROM) and the needed torque. The SAMA exoskeleton was manufactured and assembled into an ergonomic custom-made wheelchair in a sitting posture in order to provide portability and subject comfort during experimental testing and rehabilitation exercises. Dynamic modeling using MATLAB–Simulink was used for calculating the inverse kinematics, dynamic analysis, trajectory generation and implementation of proportional–integral–derivative (PID) computed torque control (PID-CTC). A new framework has been developed for rapid prototyping (the dynamic modeling, control, and experimentation of SAMA) based on the integration between MATLAB–Simulink and the Robot Operating System (ROS) environment. This framework allows the robust position and torque control of the exoskeleton and real-time monitoring of SAMA and its subject. Two joints of the developed exoskeleton were successfully tested experimentally for the desired arm trajectory. The angular position and torque controller responses were recorded and the exoskeleton joints showed a maximum delay of 200° and a maximum steady state error of 0.25°. These successful results encourage further development and testing for different subjects and more control strategies.
The Impact of School Heads’ Technology Leadership on Teachers’ Technological Proficiency and Academic Optimism

The adoption, integration, and use of technology in the classroom should be planned by school leaders and teachers, who should also arm themselves with the newest technological developments. This study was designed to determine the impact of school heads’ technology leadership to teachers’ instructional innovation and academic optimism during the COVID-19 period. The study utilized a quantitative research design and a descriptive-correlational research method and was confined among 31 school heads and 651 teachers in Candelaria East and West Districts during the S.Y. 2021-2022. The survey-questionnaire, which was developed by the researcher and validated by research practitioners and experts, was the primary data gathering tool. From the findings, it was deduced that there is no significant difference between the perception of the elementary and secondary teachers on the school head’s technology leadership, teachers’ technological proficiency, and teachers’ academic optimism. It revealed that the social, legal, and ethical issues; and the leadership and vision significantly predict the teachers’ technological proficiency while the social, legal, and ethical issues; leadership and vision; productivity and professional practice and support; and management, operations, and finance significantly predict the teachers’ academic optimism. In light of the findings and conclusion, the study recommends that DepEd may include the nature and concept of digital citizenship in school management and leadership.
Applications of the Novel Quantitative Pharmacophore Activity Relationship Method QPhAR in Virtual Screening and Lead-Optimisation

Pharmacophores are an established concept for the modelling of ligand–receptor interactions based on the abstract representations of stereoelectronic molecular features. They became widely popular as filters for the fast virtual screening of large compound libraries. A lot of effort has been put into the development of sophisticated algorithms and strategies to increase the computational efficiency of the screening process. However, hardly any focus has been put on the development of automated procedures that optimise pharmacophores towards higher discriminatory power, which still has to be done manually by a human expert. In the age of machine learning, the researcher has become the decision-maker at the top level, outsourcing analysis tasks and recurrent work to advanced algorithms and automation workflows. Here, we propose an algorithm for the automated selection of features driving pharmacophore model quality using SAR information extracted from validated QPhAR models. By integrating the developed method into an end-to-end workflow, we present a fully automated method that is able to derive best-quality pharmacophores from a given input dataset. Finally, we show how the QPhAR-generated models can be used to guide the researcher with insights regarding (un-)favourable interactions for compounds of interest.
Fast Multibeam Training for mmWave MIMO Systems With Subconnected Hybrid Beamforming Architecture

In this article, we present novel multibeam training strategies for millimeter-wave communication systems with the subconnected hybrid architecture. To begin with, we propose an iterative selecting search (ISS) algorithm that can reduce the training complexity of multibeam training by a large margin, and its central concept is exploiting the prior information of scanned beam combinations to iteratively optimize the beam of each subarray in order to determine the possible optimal beam combination. Then, we apply the concept of the ISS algorithm to optimize the original beam set in line with channel sparsity, with the goal of effectively characterizing the large original beam set with a small beam subset, resulting in a much smaller search space for the optimized beam subset than for the original beam set. Furthermore, we adopt two linear search algorithms on our optimized beam subset to develop efficient multibeam training methods. As shown in the simulation results, the ISS scheme shines in terms of low training complexity but performs poorly in spectral efficiency. In comparison to individual linear search methods, beam-subset-optimization-based linear search schemes not only have a greater spectral efficiency, but also have a very low training complexity.
Use of Seprafilm in a Patient With Recurrent Small Bowel Obstruction: A Case Report

Small bowel obstruction (SBO) is an emergency that should be managed early to reduce the risk of bowel perforation, strangulation and subsequent life-threatening organ dysfunction caused by sepsis. A prompt diagnostic workup including imaging and lab studies is required to assess the severity of the obstruction and to establish if emergency surgery is required. We report the case of a 55-year-old male with a history of recurrent SBO, previous ventral hernia repair and indications of previous colonic tubular adenoma per colonoscopy findings. The patient underwent an exploratory laparotomy procedure and adhesiolysis to release the SBO. This case report emphasizes the safety and efficacy of Seprafilm placement intraoperatively in decreasing the occurrence of postoperative adhesions in abdominal laparotomy procedures.

Analisis Stabilitas Artificial Reefs Tipe Hexagonal

In solving the problem of abrasion and also protecting marine ecosystems, it is necessary to come up with an idea, namely a wave energy retaining structure that is also capable of being a habitat for marine biota. Therefore, in this study, artificial coral reefs were tested which are considered capable to solve these problems, plus those which at the same time rehabilitate damaged coral reef ecosystems. The artificial reefs model in this test is a hexagonal type with one layer arrangement. To get the success value (K D ) of artificial reefs, it is seen from the percentage of damage caused by the influence of height and wave period. Then the K D value was calculated using the Hudson formula so that it was found that the hexagonal type artificial reefs had a K D value = 1.2.
Operational crisis communication management: a content analysis of FIFA’s communication during Covid-19

ABSTRACT Despite the high number of crises encountered within sport, crisis communication management in sport remains understudied. Operational crisis communication in particular can be considered an uncharted territory, regardless of its potential significant effects on sport organisations’ reputation. In this study we explore the themes used in FIFA’s communication during the Covid-19 pandemic, to understand how operational organisational crisis communication was managed by football’s leading sport organisation in this unprecedented climate. Content analysis is conducted in all FIFA’s press releases and Twitter messages related to Covid-19 from March 5th to July 3rd 2020, in order for insights to be offered to the content and meaning of FIFA’s operational crisis communication, their attempts to emphasise the organisation’s positive traits and actions, and the links built with managing and improving the organisation’s reputation. The analysis of the themes used indicates that proactive planning of crisis communication management had been conducted, while lessons from previous handling of crises appear to have been learned. By outlining the crisis communication strategy adopted by FIFA, we offer insights to the unexplored area of operational crisis communication in sports, while presenting a roadmap for operational crisis communication management for other sport organisations and future studies exploring the topic. HIGHLIGHTS The study highlights the main themes used by FIFA, focusing on positive traits of the organisation. FIFA’s crisis communication management deviates from pre-prescribed recommendations. A roadmap for operational crisis communication management for sport organisations is offered.
BOOK OF GRADUATES

be informed about this. Men claim that they are better informed than women. Higher educated people claim they are better informed than the middle and lower educated. People who want more information have significantly more trust in the information sources than people who do not want to be informed. There is some potential for dialogue in the Netherlands on the future role of nuclear energy as an energy source considering the general attitude toward nuclear energy and the expressed need for learning on advantages and disadvantages. It will be a great challenge for all actors in the nuclear field to engage in the dialogue as well as to inform and involve the public. Trust is a prerequisite for dialogue and therefore trusted actors are needed. This study shows that there is much work to be done by actors in the nuclear field who are regarded as not trustworthy, especially the media. Trusted actors, in particular scientists, have a responsibility to build on the trust that is given to them. The insights presented here give directions to both proponents and opponents of nuclear energy who intend to formulate a communication strategy in order to reach their audiences. The results of this study can act as a starting point for further research, in particular explanatory research into the causes of the expressed opinions. to different types of CEO communication. Despite the positive attitude towards CEO activism, expected risks—such as the chance to offend people, reputational damage, loss of customers, dissatisfied shareholders, or self-glorification—prevail, and most business leaders choose to stick to their businesses. At the same time, CEO activism is considered inappropriate and unsustainable, as it allows an individual CEO to bear the burden of a better society. In the Netherlands, the focus is extended to col-lectivity and interaction between companies and society in which they operate. As for collectivity, shared responsibility is suitable if we are to address social issues and to bring about changes.
Security Analysis and Improvement of Vehicle Ethernet SOME/IP Protocol

The combination of in-vehicle networks and smart car devices has gradually developed into Intelligent Connected Vehicles (ICVs). Through the vehicle security protocol, ICVs can quickly realize communication transmission. However, with the more frequent connections between smart in-vehicle devices and the network, the relationship between intelligent cars and external systems is becoming more and more complicated, and in-vehicle networks are gradually facing many security issues. Strengthening the security of in-vehicle protocols has become particularly important. This paper uses the model building method based on the Colored Petri Net (CPN) theory to model the Scalable service-Oriented MiddlewarE over IP (SOME/IP) protocol of the vehicle Ethernet. The security protocol is formally verified and analyzed by combining it with the Dolev–Yao adversary model detection method. After verification, the protocol is subject to three attack vulnerabilities: replay, tampering, and deception. We introduce timestamps and random numbers to strengthen the protocol security. After the final analysis and verification, the improved scheme in this paper can effectively improve the security performance of the protocol.

Given the extensive body of recent scientific contributions in this discipline, a comprehensive review of deep learning developments in the domain of diabetic retinopathy (DR) analysis, viz., screening, segmentation, prediction, classification, and validation, is presented here. A critical analysis of the relevant reported techniques is carried out, and the associated advantages and limitations highlighted, culminating in the identification of research gaps and future challenges that help to inform the research community to develop more efficient, robust, and accurate DL models for the various challenges in the monitoring and diagnosis of DR.
Thermally induced phase transforming cellular lattice driven by bimetal beams

Phase Transforming Cellular Material (PXCM) exhibits transformation by loading and maintains the deformed shape even after unloading after compression and restores the original shape by deforming in the opposite direction. Conventional PXCM needs to be stressed reversely to restore its original shape. Bimetals, i.e., clad sheets of metals with large differences in the coefficient of thermal expansion, can spontaneously bend in response to temperature changes because of thermal stress. In this study, we designed a lattice structure that not only deforms when a compressive/tensile load is applied but also changes its shape by heating/cooling by using bimetal for the curved beam of PXCM. A newly created PXCM is named thermally induced PXCM. The TI-PXCM exhibited a large recovery strain of 20% or more with a temperature hysteresis of 302 K in the temperature range of − 190 to 200 °C.

Bahri and Sosial, said there is two ways on prevention user from online fake news when using social media is with cognitive skill and critical thinking. Another way is stated by BNPT, social media user is suggested no to easily trust one piece of information when the source is not clear. Check news content and sources deliver news. Third and fourth, corrects and compare the information can trust or not. Fifth, do not spread it to other if user not sure validity of information. KOMINFO also said social media user must be careful with provocative titles, pay attention to the site address that information, fact check, check the authenticity, and joint anti Hoax forum to prevent social media user trapped in online fake news. Kementrian Agama also said, social media user must be able to filter the truth of the information circulating before it spreads. Second, remember ethics in social media. Third, be careful of unknown accounts. Fourth, do not upload information that conflicts with Sara. Fifth, use social media to expand the network. Sixth, include the source of the information content uploaded. Seventh, do not upload information when source is not clear. And lastly, using social media for self-development. Allah SWT also says in Surah Al-Hujarat:6 and An-Nur: 19 to verify all information that we get and do not spread fake news.
Is Physical Activity an Effective Factor for Modulating Pressure Pain Threshold and Pain Tolerance after Cardiovascular Incidents?

The purpose of this study was to investigate whether regular physical activity can alter the pressure pain threshold, pain tolerance, and subjective pain perception in individuals who have experienced a cardiovascular event. The study involved 85 individuals aged 37 to 84 years (M = 65.36) who qualified for outpatient cardiac rehabilitation, which consisted of 24 physical training sessions. The patients were all tested twice: on the first and last day of the outpatient cardiac rehabilitation program. Assessments of the pressure pain threshold and pain tolerance were performed with an algometer. To assess the pain coping strategies, the Pain Coping Strategies Questionnaire (CSQ) and parenting styles were measured retrospectively with subjective survey questions. The main results of the study showed that patients achieved significantly higher pressure pain thresholds after a physical training cycle (ps < 0.05, η2 = 0.05–0.14), but found no differences in the pain tolerance (ps > 0.05). A lower preference for the better pain coping strategy explanation (ß = −0.42, p = 0.013) and growing up in a family with a less neglectful atmosphere (ß = −0.35, p = 0.008) were associated with increased pressure pain threshold after physical training. The results suggest that physical activity is an important factor in modulating the pressure pain threshold.
The Low State Temperature Distribution and First Chemical Abundances of White Dwarfs in Polars

During the low optical brightness states of AM Herculis systems (polars) when accretion has declined to a very low value, the underlying magnetic white dwarf photosphere can be modelled without the complication of thermal bremstrahlung and cyclotron emission from the luminous accretion column. The far ultraviolet spectra can be modelled with high gravity solar composition photospheres. In this way, I present new temperatures and the first chemical abundance estimates for the white dwarfs in three selected polars from the IUE NEWSIPS archive. For the white dwarf in V834 Cen with Teff = 16,000$K, Si/H = 0.1 solar, C/H = 0.5 solar, for BY Cam, Teff = 17,000 K, Si/H = 0.1, C/H = 5 solar and for RX J1313-32, Teff = 22,000 K, Si/H = 0.1 solar, C/H = 0.1 solar. The temperature distribution of 24 white dwarfs in polars with known temperatures above and below the period gap is compared with the distribution of the white dwarf temperatures in dwarf novae during quiescence. In both cases, the magnetic white dwarfs in polars are significantly cooler than the non-magnetics. For all CV white dwarfs, magnetic and non-magnetic with Teff < 12,500 K, 91% of the objects (10 out of 11) are magnetics in polars. This suggests that long term accretion heating and cooling of white dwarfs in polars differs from the effects of long term accretion in non-magnetic disk accretors.
Diaspores biometry, temperatures and light regime on seed germination of Ptychosperma macarthurii (Arecaceae)

This work aimed to analyze diaspores biometric characteristics, the effect of different temperatures and light regimes on seed germination and on the initial seedlings’ growth of Ptychosperma macarthurii. The experiment was performed at the Horticulture Seed Laboratory, UNESP/FCAV, Jaboticabal, SP. The individual diaspores biometric analysis was performed by measuring the length, diameter, mass and weight of a thousand diaspores, the data were subjected to descriptive statistical analysis. It was adopted a completely randomized design in a 5 × 2 factorial with four replications of 25 seeds per treatment. Five temperatures (25; 30; 35; 20-30 and 25-35 ºC) and two light regimes (presence and total absence of light) were evaluated. The variables analyzed were germination, germination speed index, average length of the primary root and shoot, diameter of the stem and seedlings total dry mass. The length, diameter and average weight of the diaspores were 12.54 mm, 6.05 mm and 0.1610 g, respectively. The seeds of Ptychosperma macarthurii germinated in a wide temperature range, reaching a higher germination percentage at 25 ºC and a higher germination speed index at 30 ºC, being classified as neutral photoblastics. The constant temperature of 30 ºC provided higher mean values ​​for all seedlings’ biometric characteristics.
