Surgical Challenges for WIOL-CF® Dislocation without Capsular Bag Complex after Trauma: A Case Report

Purpose: To present a case of post-traumatic dislocation of the WIOL-CF<sup>®</sup> accommodating intraocular lens (IOL), composed of hydrogel material and featuring a full-optic body design, in a vitrectomized eye, highlighting considerations for surgical correction.Case summary: A 54-year-old man with a history of left-eye WIOL-CF<sup>®</sup> implantation and vitrectomy experienced sudden onset of vision deterioration in the left eye following trauma. The IOL was dislocated due to posterior capsule rupture, with the anterior capsulorhexis margin intact. The support-less circular design and material properties made it challenging to grasp the dislocated IOL in one attempt, and there was a risk of tearing when using intraocular forceps and an extrusion needle.Conclusions: The case of WIOL-CF<sup>®</sup> dislocation without the capsular bag emphasizes the importance of considering the structural vulnerability and propensity for fragmentation of the IOL during removal. Adequate corneal incision size, active utilization of perfluorocarbon liquid to approximate the IOL to the anterior chamber, and gentle removal in one attempt without applying excessive force are crucial steps in the removal of a dislocated IOL.

OS ASPECTOS SOBRE A LEGITIMIDADE DA AÇÃO POLICIAL MILITAR E A RESPONSABILIDADE JUDICIAL: UMA ANÁLISE DA VIOLÊNCIA INSTITUCIONAL E DA IMPUNIDADE

The present study aimed to analyze aspects related to the legitimacy of military police actions and judicial accountability, focusing on institutional violence and impunity. The research begins by examining how the legitimacy of police actions is constructed and perceived by society, and it further investigates the legal consequences of police actions, especially when they involve abuse of authority or excessive use of force. In this context, it highlights the importance of assessing the legal and ethical boundaries of military police actions and the role of the justice system in holding these actions accountable. For the development of this study, a bibliographic and qualitative methodology was adopted. The analysis was based on existing literature on the topic, including legislation, academic articles, theses, dissertations, and other relevant documents. This approach allowed for an in-depth understanding of the historical, cultural, and institutional processes that influence both police conduct and the judicial system's response in cases of institutional violence.The results indicate that, in many cases, there is a gap between what is established by law and the actual practices on the streets, particularly regarding the use of force and abuses committed by certain security agents. It was observed that impunity in specific cases of police violence generates a perception of distrust in society toward the institutions responsible for enforcing the law, which directly impacts the legitimacy of police actions.

The relationships between law enforcement authorities and underground raves: a case study of OTUM rave festival in the Maldives

ABSTRACT This article analyzes the relationship between underground raves and law enforcement authorities. It is centred on the police raid of the OTUM rave festival held on the uninhabited island of Anbaraa in the Maldives, specifically focusing on the perceptions of ravers present during the raid of the OTUM rave festival. The data on which this paper is based stems from open-ended interviews with ravers who were present during the raid. Ravers felt that police used excessive force at the rave festival. They arrested 79 ravers for possessing recreational substances, including LSD, cannabis, and ecstasy. The police raided the rave festival due to pressure from religious clerics and to appease the more conservative members of the mainstream society. The results from this study suggest that treating ravers as criminals and threatening them with imprisonment creates a disconnection between the underground rave community and the mainstream society, widening rather than healing divides and reinforcing ideas of deviance and resistance.

The Influence of Group Identification and Morality in Support for Defunding the Police

There is very little research regarding what factors drive support for defunding the police. Using the theoretical framework of the Group Engagement Model and the Moral Foundations Theory, this study explores if and how race, group identification, and morality shape support for defunding the police. Results indicated that increased superordinate identification and binding moral foundations reduced support for defunding the police among White respondents. For Black respondents, increased subordinate identification explains their increased support for defunding the police. Attachment to one’s racial group and concerns for its welfare coupled with moral intuitions driven by care and fairness toward victims of police brutality who are disproportionately Black explains why Blacks Americans began and support calls to defund the police.

The Internationalization of #BlackLivesMatter: Solidarity From Minneapolis to Gaza

This article aims to better understand the contemporary nature of Black-Palestinian solidarity by directly speaking to activists and explain why US-based Anti-Police Brutality Movements, like Black Lives Matter, share a sense of common solidarity with Palestinians. We argue that solidarity by US-based anti-police brutality movement activists with Palestinians has become more salient since the 2014 Ferguson Protests and especially since the 2020 George Floyd protests that started in Minneapolis, Minnesota. Interviews with activists in Minnesota reveal that interviewees tend to highlight a shared sense of oppression with Palestinians, which is largely perceived through symbolic images and videos shared on social media. Moreover, we find that the Covid-19 pandemic served as a catalyst for the unprecedented mass mobilization that followed the murder of George Floyd. The Covid-19 pandemic, the simultaneous struggle with similar injustice frames occurring in both Ferguson and Gaza, and the powerful images and videos of oppression and police brutality all influenced increasing solidarity and connections among these two disparate struggles.

“We're tired of this Weber guy!”—Force experts, police reforms, and the violence of standardization

AbstractSince the mid‐2000s, the use‐of‐force continuum—a global standard for providing law enforcement with guidelines on the proportionate use of force—has been central in Turkish police training and reporting practices. Liberal police accountability tools, like the use‐of‐force continuum, rely on standardization to prevent police violence. Yet these techniques still result in maimed bodies and psyches and police impunity. Rather than taking the standardization of police force simply as a failed project, a sham, or a mere techno‐fix, I examine how powerful actors like police align with such standards and how they start thinking and acting through them while repurposing them. Drawing on 18 months of fieldwork between 2015 and 2017 among the Turkish National Police, I show how the transnational standardization of police force has in fact enabled police in Turkey to redefine and ultimately reclaim the violence they are professionalized in as what I call “force experts.” Force defies standardization in both theory and practice; however, what sanctions police violence now is not just technical standardization but the expert framing of the democratically reformed police force. This is the violence of standardization, especially in contexts where governments retool reforms to criminalize suspect Others whom they perceive as a “threat” to their rule.

Multi-objective optimal design of Tuned Mass Damper Inerter for base isolated structures

The BIS-TMDI is a hybrid control strategy that significantly reduces the seismic response of structures compared to conventional BIS through proper tuning, albeit with the trade-off of increased control forces exerted by the TMDI on the host building structure. However, these potentially significant forces are generally not considered in current TMDI tuning approaches. In this paper, a multi-objective optimization design method is herein developed to determine the compromise between the competing objectives of suppressing earthquake-induced vibrations in buildings and avoiding the generation of excessive control forces of TMDI. The study shows that under non-stationary excitations, the average control force of the TMDI system can be reduced by 16% compared to single optimization constraint, with a maximum reduction of up to 25%. Finally, the optimization design methods of this paper are applied to an 8-story frame as a validation case.

Vote choice in the context of lethal police violence: A research note

Do police-caused deaths predict presidential vote choice in the US? This study explores the relationship between lethal police violence and vote choice in the 2020 presidential election using individual-level data from Harvard University's Cooperative Election Study (CES), which has been linked with aggregate-level data on police killings, civilian homicide rates, and socioeconomic, political, and public health characteristics. Consistent with the issue ownership theory of voting, this study finds that voters living in areas characterized by lethal police violence are significantly more likely to vote for the Democratic Party above and beyond their individual-level attributes and other contextual conditions. These findings and supplemental analyses raise critical questions concerning the political salience of fatal force in presidential races in the post-2020 era. Findings also support the need for further criminological inquiry into the effects of different forms of violence on American political behavior.

From Microaggressions to Viral Trends: A Qualitative Examination of Black Emerging Adults’ Experiences With Online Racial Discrimination

This study examines how Black emerging adults experience and perceive online racial discrimination. We systematically analyzed responses from 260 Black college students (aged 18-29) at a predominantly White institution in the Midwest, collected during the fall 2020 semester. Utilizing a two-step approach, we identified emerging themes in their experiences, then examined these themes through the lens of the Taxonomy of Online Racism (TOR), allowing us to understand how different manifestations of ORD intersect and relate. Content analysis revealed eleven forms of ORD, with Microaggressions ( n = 67), Encounters with Content Related to Police Violence Against Black Individuals ( n = 46), and Exposure to Anti-Black Lives Matter Sentiments ( n = 44) being the most prevalent. We also find that ORD is a complex phenomenon, shaped by factors such as current events and individual interpretations, which can differ from established definitions in research and policy.

Evaluating the Accuracy of Virtual Reality in Replicating Real-Life Human Postures and Forces for Injury Risk Assessment.

The objective of this study was to assess the accuracy of virtual reality (VR) technology in replicating real-life environments for the adoption of appropriate human postures and forces. Despite the widespread implementation of VR in various applications, there is a lack of research evaluating the accuracy of human postures and sensory aspects in the VR environment compared to real-life scenarios. A total of twenty-two student participants were recruited for this study, which involved a common lifting task. Two specific poses were identified as having potentially excessive forces exerted on the lower back. By comparing the angles of seven anatomical joints in both the real environment and the VR environment at each pose, we observed that depth perception may influence posture adoption in the VR setting. Moreover, the presence of a physical load applied to both hands significantly influenced the postures adopted by participants compared to those in the VR environment. These deviations in postures directly led to significant differences in predicted spinal forces exerted on the lower back, which in turn could result in inaccurate assessments of injury risks and the design of injury prevention programs. Therefore, it is crucial to understand the accuracy of VR technology as a substitute for real-life environments.

Chicago Police Torture and the Limits of Human Rights Enforcement in Liberal Democracies

From 1972 to 1991, a network of Chicago Police detectives used torture to force confessions from over 100 criminal suspects. Almost all were Black men, and many were wrongly convicted, some for capital offenses. I synthesize insights from comparative research on human rights, state abuse, and police violence in democracies to explain why, for nearly two decades, liberal institutions in Chicago failed to stop the torture. I argue that the nature of state violence in this case—targeting marginalized individuals uninvolved in political activity—intensified the practical, affective, and informational obstacles that are inherent to activating liberal institutions—courts, elected officials, media, and civil society—to fulfill their roles as rights enforcers. Applying these literatures to a type of case they typically overlook—a wealthy liberal democracy—contributes to understanding why state violence persists in such states and why it tends to concentrate on marginalized populations.

Government justification of police actions against protesters: biopolitics in Poland during the Covid-19 pandemic

ABSTRACT How did the government justify aggressive, and, at times, violent police actions against demonstrators during the pandemic? We use a biopolitical framework to empirically explore how leading members of Poland’s government justified protest policing. During the Covid-19 pandemic, Poland’s PiS-led government, like others across Europe, implemented social distancing measures that curtailed the right to peaceful assembly. The government justified aggressive crowd control tactics such as kettling to ‘protect’ society from what they perceived as illegal and unruly protestors who seek to cause indirect mass harm, e.g. spread the virus via street protesting, or cause direct harm to police officers through physical acts of protester aggression. The government argued that protesters, instead of being whom the state must keep safe from biological harm, actually threaten a vulnerable police force and other institutions. The government projected their own vulnerability to cast protesters as biological threats to the nation and, thus, as dangerously norm-breaking ‘others,’ in order to justify surveillance of demonstrators and aggressive police tactics.

Analisis Postur Kerja Pada Bagian Packing Menggunakan Metode ManTRA Dan REBA

PT. Indonesia Plafon Semesta is a company engaged in manufacturing, this company produces various kinds of PVC ceilings. Problems faced by PT. Indonesia Plafon Semesta is the activity of making PVC ceilings in the packing section, where the activity conditions or workers' posture is not good. When packing by squatting and bending, the position is less ergonomic, resulting in excessive force exertion and the risk of injury. This research aims to determine the level of complaints felt by workers in body parts by identifying them using the Nordic Body Map (NBM), Manual Task Risk Assessment (ManTRA) to determine the level of risk experienced by workers and knowing how many angles are formed. Rapid Entire Body Assessment (REBA) is used to calculate worker posture and provide a score of the worker's proposed posture using Anthropometry. Data processing was carried out using NBM calculations for workers who had the highest score of 51 and the lowest 44. Knowing the level of risk experienced by workers with Mantra protection with the back, forearms, neck and wrists &gt; 15 and the angle formed in the REBA calculation using score 10. Improvement of the proposed posture with Anthropomerti with a TPO calculation of 32.5 cm and JTD cm of 69 by paying attention to the object being worked on with REBA calculation results having a score of 7.

Tooth accidental displacement in extraction manoeuvres: a series of two cases

Tooth displacement in bordering anatomical areas is a rare and challenging complication that might occur in the attempt at tooth extraction. Displacement may be attributed to multiple factors, including inadequate clinical evaluation before surgery, an inappropriate extraction plan, the application of excessive force, the use of an incorrect surgical technique, or a lack of experience on the part of the operator. Additionally, anatomical characteristics of the patient must be considered. In this report, we present two examples of tooth displacement and describe the surgical approach adopted to achieve tooth removal.

Race, Political Ideology, and Support for Defunding the Police in the United States

ABSTRACT This study investigates public attitudes toward “Defund the Police” proposals amid U.S. protests against racism and police brutality. Analysis of 2021 General Social Survey data reveals that racial identity and political ideology significantly shape these attitudes. Black Americans demonstrate the highest support for defunding, followed by Hispanic Americans and other racial and ethnic minorities, reflecting diverse historical and cultural experiences with the government. Political ideology further polarizes opinions, with liberals more supportive and conservatives more opposed. These findings highlight the complexities of addressing systemic issues in criminal justice and the importance of social identities in shaping attitudes toward police reform.

‘We Don’t Have Any Honor Because We Are khwaja sira’: Police Violence and Discrimination Against the Khwaja Sira Community in Swat, Pakistan

Abstract This qualitative study examines police violence and discriminatory policing practices targeting the third gender community, known in Pakistan as khwaja sira. Employing a phenomenological analysis, we conducted a qualitative study involving in-depth interviews with 45 khwaja sira in Mingora, Khyber Pakhtunkhwa, Pakistan, recruited through purposive and snowball sampling. Using Interpretative Phenomenological Analysis of the interview transcripts: two distinct themes emerged regarding the lived experiences of khwaja sira in Swat, Pakistan: experiencing multiple forms of violence by police; and managing abuses of policing power. Findings shed light on the challenges khwaja sira face regarding police violence and misconduct, including neglect from law enforcement officers to register their cases, biased practices within police precincts, and discrimination associated with their engagement in sex work or their gender nonconformity. Findings underscore the need for comprehensive interventions aimed at addressing police violence experienced by the khwaja sira community.

Development of an Algorithm for Determining the Class of an Obstacle in the Process of its Interaction with the Manipulator

The article discusses the problem of determining the nature of an obstacle using a force sensor for terrain mapping. Three classes of objects have been introduced: the first class is "static" obstacles, the second class is "moving" obstacles, the third class is "unstable" obstacles. To conduct experiments, a simulation system was built in the Gazebo modeling environment, including a manipulator with the ability to horizontally move a probe with a force sensor and a set of obstacles corresponding to three classes of obstacles. All experiments were carried out using the ROS framework, the Gazebo simulator and the Movelt manipulation software. Processing of signals from the force sensor showed that the sig­nals for the three classes of obstacles are different, which makes it possible to identify the class based on sensor readings. Based on the analysis of data received from the sensor, rules were formed that make it possible to determine the class of an obstacle during its interaction with the manipulator in real time. To determine the obstacle class, the values of the force sensor signals are considered, smoothed by the moving average method. According to the rules discussed in the article, an algorithm was developed to determine the class of obstacle, which was implemented in the Gazebo modeling environment. Testing of the algorithm showed the stability of its operation under the given experimental conditions. Successful determination of the obstacle class will allow one not only to construct a map of the area, but also to prevent damage to the device when exposed to a "static" object with excessive force. The presented approach can be expanded to narrower classes of obstacles that characterize objects that can be encountered by a mobile device when mapping a forest area.

Income level as a differentiating factor in assessing the impact of migration on economic growth

Aim. To study the nature of the impact of migration on economic growth depending on the level of gross domestic product (GDP) per capita and the direction of migration flows.Objectives. Study of theoretical approaches to the research of the impact of labor migration on economic growth; analysis of factors that differentiate the assessment of the impact of migration flows on economic growth indicators; collection and analysis of statistical information for the development of econometric models for assessing the impact of migration on economic growth.Methods. The authors used general scientific methods of research, such as deduction, analysis, synthesis. Statistical methods of data analysis were applied, linear regression models were built.Results. The research shows that the impact of migration on economic growth in countries with different levels of GDP per capita is due to different factors. For developed economies, the positive factors of the impact of immigration on economic growth are replenishment of scarce labor resources; improvement of labor force quality due to structural changes caused by the transition of the permanent working-age population to new professional fields. For countries with a low level of GDP per capita we can identify a number of positive factors of the impact of emigration (with a negative balance of migration growth) on economic growth. In particular, the outflow of excess labor force creates conditions for reducing unemployment; remittances of migrants support effective demand in the consumer market, contribute to the development of the banking system and investment in the country of origin; the expansion of social ties leads to the development of human capital, increasing the potential for innovation.Conclusions. The value of correlation coefficients in the constructed regression models indicates that there is a weak correlation between the variable characterizing the volume and nature of migration in the country (the ratio of migration balance to population) and the variable characterizing economic growth (GDP per capita at purchasing power parity) only for the group of high-income countries. There is little statistical dependence of these variables for other groups of countries. With regard to econometric modeling of the impact of migration on economic growth, this means that it is necessary to develop separate models for each group of countries depending on the level of GDP per capita and the direction of migration flows.

Underlying Dimensions of Racial Residential Segregation and Police-Caused Homicide of Blacks: A Cross-Sectional Analysis of Core Based Statistical Areas

This work builds upon previous research to assess the associations between underlying dimensions of racial residential segregation and police-caused homicide of Black civilians. Previous scholars have observed that much of the existing work on residential segregation and police-caused homicide has used one measure of segregation, most commonly the dissimilarity index, although recent work has expanded the focus to include multiple indicators of segregation. Our research extends this research by computing multiple measures of racial residential segregation for a sample of U.S. Core Based Statistical Areas in 2010 and factor analyzing them to identify underlying dimensions. Measures of the resulting dimensions are merged with the Mapping Police Violence data on police-caused homicide. The analyses reaffirm and extend previous conclusions about the importance of spatial relationships within residential locations for understanding contemporary police-caused homicide, while raising questions about the underlying theoretical mechanisms.
