Application of Volume‐of‐Fluid Method to Analyze the Viscosity Effect on the Spine Formation of Bloodstains

In bloodstain pattern analysis, the blood droplet volume and surface impact velocity play an important role, and many related experimental studies have been carried out. If an appropriate computational fluid dynamics (CFD) model that could solve bloodstain patterns, especially spine formation bloodstain patterns, can be obtained, the blood droplet volume and impact speeds at various crime scenes can be predicted more accurately. For this purpose, Flow‐3D software using the volume‐of‐fluid method was applied to analyze the behavior of human blood droplets during an impact event, especially focusing on the viscous effect on splashing, which forms the spine which can be used to predict the impact velocity. To obtain a non‐Newtonian viscosity model of blood for a computational fluid dynamic analysis, the venous blood samples of 163 people were tested using a hemorheology instrument. Among the venous blood samples of 163 people, 37 samples for which all blood test results were in a normal range were selected for the non‐Newtonian viscosity modeling. From the CFD analysis, it could be concluded that a non‐Newtonian viscosity model is more appropriate than a constant viscosity model for predicting splashing that forms the spine. The gradient of the non‐Newtonian model at a high shear rate has more of an effect on spine formation than that at a low shear rate. The lowest viscosity with a high velocity at the outer front of the radiating flow plays an important role in forming the splashing pattern.     

Networked and Polycentric Governance in South Korea: The Case of Dam Politics after Devolution

The South Korean intergovernmental environment has undergone drastic changes after the reintroduction of local autonomy in 1995. This study investigates how and why the governance has changed in terms of its structure and processes after devolution using the case of dam politics in South Korea. It also addresses the accountability implications of the changed governance. This study analyses two cases of dam construction initiative, which are the Youngwol dam project (1990–2000) and the Hantangang dam project (1998–2004). The analysis of these cases reveals that the governance structure concerning water resource supply has changed from a form of policy community, which can be characterized by its closed membership and stability in relationships, to a form of issue network, where the membership is enlarged to include various participants. More specifically, there are three important findings. First, the cancellation of the Youngwol dam project served as the moment to establish and empower a network of opposition against dam building, which had long been advocated and led by the policy community comprising the Ministry of Construction and Transportation, Korea Water Resources Corporation, engineering experts, and some private companies related to dam construction. Second, as the central government plans to build 12 more dams including Hantangang dam, the network of opposition tends to be further vitalized with heated participation from local activists, some water resource management experts, and environmental activists. Third, as the pro-dam policy community and the network of opposition initiate dialogue among themselves, they are forming an issue network which works as a governance mechanism in the area of water resource supply management.     

Co-opting Good Governance Reform: The Rise of a Not-so-Reformist Leader in Kebumen,Central Java

Challenging the existing literature, which tends to downplay the impact of good governance reform in post-Suharto Indonesia, the article suggests that greater intervention by international donors, combined with the process of decentralisation, has influenced the dynamics of political competition at the local level. It suggests that the increasing availability of international aid has provided local elites with an option to engage in a new form of patronage politics that relies less on old instruments, such as money politics and violence. By selectively committing themselves to good governance reform, Indonesian local elites can now seek a new source of power in the form of support from international donors, with which they can raise their profiles as ‘reformists’ and consolidate power, only to engage in familiar, if less blatant, forms of patronage politics. The article highlights such a dimension of local politics with reference to the case of Kebumen's former regent, Rustriningsih.     

‘Joe everyday,people off the street’: a qualitative study on mediators’ roles and skills in victim–offender mediation

This qualitative study examined multiple perspectives of participants who experienced a Victim–Offender Mediation (VOM) program in a Midwestern city in the United States. Of particular interest are the roles and skills of mediators. Data consisted of 34 face‐to‐face interviews with 37 participants including adult crime victims, juvenile offenders and their parents, mediators and representatives from referring agencies. Insider perspectives regarding the roles and skills of the mediators in restorative processes were revealed through personal stories. Although the majority of the participants reported that the roles and skills of mediators were consistent with restorative justice principles, this exploratory study also revealed that some roles and skills exhibited by mediators were inconsistent with restorative justice values, which shows the variance of ‘real world’ restorative justice. Recommendations are made to promote mediators’ roles and skills that are compatible with restorative justice principles.     

Uncertain allies or uncomfortable neighbors? Making sense of China–North Korea Relations, 1949–2010

Abstract

This study is based upon two premises: (1) the available literature, though voluminous, fails to provide systematic understandings of the complex and evolving relations between China and North Korea; and (2) China and North Korea had been short of being trusted allies bound in blood and belief even before the launch of post-Mao reforms and the normalization of Beijing–Seoul relations. This article dissects this curious relationship into four questions: (1) What does history inform us about China's relations with (North) Korea? (2) Has China communicated effectively with North Korea? (3) Have China and North Korea been ‘trusted allies’? (4) How effective has China been in inducing North Korea to comply with its demands over the years? The authors argue that, geo-strategically, China can hardly afford to put North Korea in an adversarial position. Furthermore, residues of the Factional Incident of 1956 and North Korea's deep-rooted suspicion of China still linger on. These have been the sources of Beijing's dilemma in consistently opting for ‘soft’ measures despite that North Korea's provocative acts and nuclear weapons programs have negatively affected China's interests. From the outset, China and North Korea had been more uncertain allies who had to cooperate with each other under the ideological and geopolitical imperatives of the difficult times. The authors also suggest that it would be misleading to put Sino–North Korean dynamics in a usual category of big power–small nation relations where power asymmetry generally works against the latter. North Korea has undoubtedly been an atypical ‘small nation’. It is due to these limitations that China's pressurizing has not been always effective and that Beijing's reactions have been continuously cyclical. This cyclical trend is not likely to be broken since the upcoming drama of Sino–American rivalry is bound to close the window of such opportunities for China, which will nevertheless regard North Korea increasingly as a liability, if not uncomfortable neighbor.     

Constructing a decolonized world city for consumption: discourses on Hong Kong Disneyland and their implications

The paper argues that, under the globalized economy, state power is far from diminishing. I study how the Hong Kong Special Administrative Region government officials in 1999 developed “competition-development” discourse and “disappearing-world-city” discourse to persuade the public to approve the unequal and non-transparent Hong Kong–Disney deal for setting up the Hong Kong Disneyland (HKDL). I also examine how newspaper reports have circulated and have reinforced these two pairs of political discourses in wider popular discourse. I further reveal, in the post-colonial context of HongKong, how the HKDL project functions to accomplish decolonization tasks and to reshape Hong Kong as a consumption-based tourist spot instead of a citizen-based participatory community.     

Japan's security policy in relation to normal statehood

The paper begins by establishing the context in which Japan's normal statehood will be based. The paper shows how difficult it is for Japan to attain the status of a normal state based on the country's political forces and the rising powers in the Asian region. The paper looks at the relationships between Japan and other nations like China and South Korea, which should be considered by Japan in order to attain normal statehood. These are countries that initially were under the control of Japan, especially in business and even militarily, but today they are assuming their own position in the world; an aspect that is considered a threat to Japan's smooth return to normalcy. The paper takes into consideration the models that Japan can adopt or adapt to attain the status of a normal state. The three models discussed are those of Britain, Germany, and France. The main aspect discussed under these models is autonomy; this is based on the fact that Japan can only attain the status of a normal state if it becomes autonomous.     

Forensic Investigation of Cooperative Storage Cloud Service: Symform as a Case Study

Researchers envisioned Storage as a Service (StaaS) as an effective solution to the distributed management of digital data. Cooperative storage cloud forensic is relatively new and is an under‐explored area of research. Using Symform as a case study, we seek to determine the data remnants from the use of cooperative cloud storage services. In particular, we consider both mobile devices and personal computers running various popular operating systems, namely Windows 8.1, Mac OS X Mavericks 10.9.5, Ubuntu 14.04.1 LTS, iOS 7.1.2, and Android KitKat 4.4.4. Potential artefacts recovered during the research include data relating to the installation and uninstallation of the cloud applications, log‐in to and log‐out from Symform account using the client application, file synchronization as well as their time stamp information. This research contributes to an in‐depth understanding of the types of terrestrial artifacts that are likely to remain after the use of cooperative storage cloud on client devices.     

Forensic Taxonomy of Android Social Apps

An Android social app taxonomy incorporating artifacts that are of forensic interest will enable users and forensic investigators to identify the personally identifiable information (PII) stored by the apps. In this study, 30 popular Android social apps were examined. Artifacts of forensic interest (e.g., contacts lists, chronology of messages, and timestamp of an added contact) were recovered. In addition, images were located, and Facebook token strings used to tie account identities and gain access to information entered into Facebook by a user were identified. Based on the findings, a two‐dimensional taxonomy of the forensic artifacts of the social apps is proposed. A comparative summary of existing forensic taxonomies of different categories of Android apps, designed to facilitate timely collection and analysis of evidentiary materials from Android devices, is presented.     

A Ferris Wheel Accident at a Movable Amusement Park

This study presented a Ferris wheel accident case. A Ferris wheel is composed of many parts, and the outmost ring of it is assembled using a lock pin. This accident occurred because the lock pin caught the door of a gondola and the gondola overturned. Five of the seven passengers in the gondola fell to the ground, along with the gondola's viewing window. The investigation revealed that the gondola became stuck when its door was caught by a lock pin at the Ferris wheel's three o'clock position. The contact between the door and the lock pin was due to a structural problem: There was not enough space allotted between the door and the lock pin. Therefore, if a passenger pushed on the gondola's door, the potential existed for contact between the door and the lock pin.
