Identification of document paper using hybrid feature extraction

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.     

Gentrification and Displacement: Modeling a Complex Urban Process

ABSTRACT

To shed some light on longstanding questions around gentrification, in this research we model environmental gentrification and gentrification-related displacement of residents. We do this through the development of an agent-based model of a simple urban region, considering different urban contexts and policy approaches to polluted facilities and the relationship of these policies with subsequent gentrification and displacement. We find that gentrification-related displacement is most likely, and most impactful, in urban regions characterized by high levels of density and low levels of residential segregation preferences. Displacement is far less prevalent in low-density regions, particularly those with high segregation preferences. We discuss the potential for different policy implications in these different urban contexts.     

Enhancing Australian Regional Policy: A Conceptual Framework for Assessing the Role of Regional Development Australia

Australian regional development has suffered from ‘fragmentation’ with policy responsibility shared between different tiers of government. The Rudd government sought to improve regional policy with the establishment of the Regional Development Australia (RDA) network. However, uncertainty surrounds the role of RDA. This paper seeks to illuminate this problem by drawing on the literature on types of multi-tiered governance, especially the work of Hooghe and Marks and Skelcher on Type I and Type II bodies. It is argued in a normative framework that the RDA network has the characteristics of Type II entities and that this gives it a comparative advantage in specific respects.     

The Current Status and Future Direction of Nanotechnology Regulations: A View from Nano‐scientists

This article presents an up‐to‐date view of leading U.S. nanoscientists' perceptions about the regulation of nanotechnology. Our analysis draws from the results of a 2011 mail survey with 444 of the most prolific nanoscientists in the United States to explore their perceptions about existing nanotech policies, the development of new nanotech policies, and mandatory policies about the implementation of safe lab practices for federally funded nanoresearch. In addition to exploring the scientists' perceptions about these pressing policy issues, we also test relationships between their perceptions about regulation and control variables such as gender, disciplinary affiliation, and political ideology. Last, the results of the 2011 data collection are compared with a similar mail survey that was conducted in 2007 with leading U.S. nanoscientists to explore any changes over the four‐year time period in scientists' perceptions about nanotechnology policy making, and governmental involvement in nanotechnology research.     

SNAKE CONFLICT-MITIGATION IN INDIA: THE KNOWLEDGE OF THE IRULA TRIBE

Nearly 46,000 people die from snakebite in India every year, so there is a real need for effective mitigating action. This depends on an understanding of snake behaviour in which the Irula excel. They are a traditional snake catching tribe and with the benefit of their knowledge it was possible to draw up a list of measures which could be taken to minimise contacts between snakes and humans.     

Continuing Professional Education for Japanese Government Officials: Study Destinations and Motivational Factors

The Japanese government's Continuing Professional Education (CPE) programs have sent officials to graduate and professional schools in Japan and abroad. This research examines the destination choice patterns of CPE participants and the reasons they choose Japanese or U.S. universities. Interviews with CPE participants suggested that U.S. schools attracted Japanese government officials by offering a wider range of courses emphasizing the integration of theory and practice. Boshier's motivational orientation model was applied to better understand CPE motivations and reasons. Notably, no participant identified “social welfare” as an important motivator, but “employment benefit” and “upgrading personal market value” factors emerged.     

Political Institutions and Public R&D Expenditures in Democratic Countries

While research and development (R&D) expenditure is crucial in a nation's competitive advantage, factors determining levels of public investment in R&D have yet to be examined. This article seeks to fill this void, focusing on different democratic institutions such as presidential versus parliamentary systems, majoritarian versus proportional electoral systems, federal versus unitary systems, bicameral versus unicameral legislatures, and the effective number of parties. Building upon theories of political institutions and government size and utilizing public R&D appropriations data from 18 Organization for Economic Cooperation and Development (OECD) countries between 1981 and 2007, this article reports that democratic institutions do matter in the levels of public R&D spending. However, the effect is more complicated across the different types and performers of research than expected. Additionally, the effect of one institutional dimension is found to be moderated by the existence of the other dimensions, which makes it clearly more challenging to sort out different degrees and directions of the relationships between R&D expenditures and political institutions.     

Why Are Some States More Generous in Offering R&D Tax Credits than Others? An Empirical Answer

This article examines political cost factors that affect a state's propensity to adopt a corporate income tax credit to encourage research and development (R&D) activities in the United States. Assuming state elected officials are vote-maximizers, this article hypothesizes that politicians' consideration of potential revenue losses and influence from organized interests are critical in a state's decision to provide a R&D tax credit. To test the hypothesis, two statistical models are specified. With a dichotomous dependent variable of whether or not a R&D tax credit is offered, a Logit regression model is utilized. For the interval level dependent variable of effective R&D credit rates, this article specifies a Tobit model. The results show that politicians' concerns about revenue losses loom much larger than private organized interests.     

Customer Satisfaction Theory in Public Administration Education: Revisiting Student Evaluation of Teaching

How has the current austerity changed the public welfare organizations’ performance landscape in modern welfare states? Can public managers make their organizations adapt to the new performance landscape shaped by the austerity? These questions are answered on the basis of the Danish case of the provision of the services to the citizens with disabilities and/or social disadvantages. The result has implications, especially for public management in praxis. The case study shows that the managers’ most important managerial tool to make their organizations adapt to the new landscape is the challenging and decision-oriented dialogue.
