Document forgery is a significant issue in Korea, with around ten thousand cases reported every year. Analyzing paper plays a crucial role in examining questionable documents such as marketable securities and contracts, which can aid in solving criminal cases of document forgery. Paper analysis can also provide essential insights in other types of criminal cases, serving as an important clue for solving cases such as the source of a blackmail letter. The papermaking process generates distinct forming fabric marks and formations, which are critical features for paper classification. These characteristics are observable under transmitted light and are created by the forming fabric pattern and the distribution of pulp fibers, respectively. In this study, we propose a novel approach for paper identification based on hybrid features. This method combines texture features extracted from images converted using the gray-level co-occurrence matrix (GLCM) approach and a convolutional neural network (CNN), with another set of features extracted by the CNN using the same images as input. We applied the proposed method to classification tasks for seven major paper brands available in the Korean market, achieving an accuracy of 97.66%. The results confirm the applicability of this method for visually inspecting paper products and demonstrate its potential for assisting in solving criminal cases involving document forgery.  相似文献

Why do some WTO trade disputes endure and recur while others do not? States have difficulty resolving trade conflicts when they involve certain types of trade-restrictive domestic regulations. While such regulations vary in their extent of legitimacy—fulfilling non-trade domestic regulatory objectives and availability of less trade-restrictive options—complainant states cannot always distinguish legitimate barriers from illegitimate ones. In such scenarios of disguised protectionism, which I argue is most prevalent with policies involving WTO’s Sanitary and Phytosanitary (SPS) Agreement, disputants confront difficulties concluding their disputes. Disputes last longer and are more likely to recur. I test the argument against a data set of WTO disputes structured in an innovative manner—one that links together related and recurring disputes into single conflicts. Both an event history analysis of conflict duration and a count analysis of conflict recurrence using this data strongly support this argument.  相似文献

The aim of this study was to verify that the combination of focused ion beam (FIB) and scanning electron microscope/energy‐dispersive X‐ray (SEM/EDX) could be applied to determine the sequence of line crossings. The samples were transferred into FIB/SEM for FIB milling and an imaging operation. EDX was able to explore the chemical components and the corresponding elemental distribution in the intersection. The technique was successful in determining the sequence of heterogeneous line intersections produced using gel pens and red sealing ink with highest success rate (100% correctness). These observations show that the FIB/SEM was the appropriate instrument for an overall examination of document.  相似文献

Little research has examined the role of acculturation in the determination of intimate partner violence (IPV) among Chinese immigrants in the United States. Data on 166 IPV Chinese immigrant couples obtained from a Chinese American community organization were analyzed for this study. Findings show that the level of acculturation and socioeconomic status were associated with severity, frequency, length, and type of abuse committed by Chinese immigrant men although not all factors played an equally important role in explaining IPV. Certain Chinese immigrant victim characteristics, such as having social networks, were also related to the experience of IPV.  相似文献

While many scholars have discussed the merits of collaborative governance, especially for addressing complicated modern policy challenges, the literature has paid less attention to how business can serve as an effective collaborative partner during the formation of mandatory policies and regulations. Drawing on scholarship in the management sciences and combining it with literature in public administration and public policy, the authors elaborate on four distinct types of business responses to proposed regulations based on degrees of political activity and social responsiveness: defensive, reactive, proactive, and anticipatory. They then characterize the reasons why proactive firms are more likely to be valuable collaborative partners with policy makers and public managers: their engagement may avoid costly stalemates that frequently hinder policy making and help develop cost‐effective, flexible policy approaches to complex social problems.  相似文献

This article discusses the link between development and peacebuilding to analyze South Korean aid activities in North Korea in the context of the Korean conflict, where there are deep-rooted cycles of conflict episodes, and to explore the possibility of aid for peace on the Korean peninsula in the future. The Korean conflict is a large part of what makes South Korean aid to North Korea ineffective. For the past 20 years, South Korean aid to North Korea has fluctuated greatly, due to the context of the Korean conflict. The Korean conflict, once seemingly on the way to resolution, appears to have reverted to a time before the end of the Cold War. Many people in both the North and the South still see each other as the enemy. Most of the South Korean aid projects in North Korea have been suspended indefinitely and the fluctuation of aid to North Korea caused serious debates within South Korean society. At one point, the debates grew so heated that they were called the ‘South–South conflict’. Building on the conceptual framework of conflict sensitive development and strategic peacebuilding, this article argues that, to overcome the current impasse, all stakeholders must better understand the context of the Korean conflict and the interaction between the context and themselves, and develop a comprehensive strategy together, to encompass the multiple issues raised by the Korean conflict, as strategic peacebuilding proposes.  相似文献

The practice of pharmacy has changed over recent years with a greater emphasis on the patient and the provision of patient care services. This expanded role of pharmacists as medication managers has resulted in changes to their professional responsibility and potential legal liability. Recent international case law demonstrates an increased legal liability of pharmacists in certain instances. However, pharmacists' liability in this new context in Australia is yet to be clarified.  相似文献

Gender disparity in sentencing outcomes has been well established in literature. Recent research has increasingly paid attention to social contexts within which judicial decision-making occurs. This study combines these two lines of research by dissecting the nature of gender disparity through ecological lenses. Using 2008–2010 federal sentencing data, we examine the roles of religious and political conservatism in affecting gender-based sentencing disparity. We find that religious and political conservatism reduces gender disparity, with the female discount dissipating in court communities with higher levels of religious and political conservatism. We also find that the conditioning effects of both religious conservatism and political conservatism on gender disparity further interact with race, with black female defendants more likely to be influenced by religious and political conservatism than their white counterparts. Overall, this study contributes to sentencing literature by demonstrating that gender disparity is deeply entrenched in the ecological contexts of court communities.  相似文献

Objectives

Examining the immigration-crime nexus across neighborhoods in the Southern California metropolitan region, this study builds on existing literature by unpacking immigration and accounting for the rich diversity that exists between immigrant groups.

Methods

Using data from a variety of sources, we capture this diversity with three different approaches, operationalizing immigrant groups by similar racial/ethnic categories, areas or regions of the world that immigrants emigrate from, and where immigrants co-locate once they settle in the U.S. We also account for the heterogeneity of immigrant populations by constructing measures of immigrant heterogeneity based on each of these classifications. We compare these novel approaches with the standard approach, which combines immigrants together through a single measure of percent foreign born.

Results

The results reveal that considerable insights are gained by distinguishing between diverse groups of immigrants. In particular, we find that all three strategies explained neighborhood crime levels better than the traditional approach.

Conclusion

The findings underscore the necessity of disaggregating immigrant groups when exploring the immigration-crime relationship.
