Power Sector Reforms and Technical Performance: Good News from an Instrumental Variable Analysis

Over the past three decades, various power sector reforms have overhauled the governance of electricity generation, transmission, and distribution in almost a hundred countries. Have these reforms produced benefits? Using instrumental variables, we improve upon earlier studies and demonstrate that power sector reforms enacted between 1982 and 2008 have both had large positive effects on the availability of generation capacity and reduced transmission and distribution losses. We also show that the positive effects on generation capacity are pronounced in developing countries and that hybrid reforms falling short of privatization and free competition are effective in improving generation capacity in particular. Overall, the results show that these reforms are an effective tool to remove an important constraint on economic growth.     

Resolving Reflection and Resolution in 3D Imaging of Fresh Bone

Structured light scanning is a noninvasive, accurate, and cost-effective 3D imaging technique, but due to reflection issues is yet to be utilized for tool mark analysis on fresh bone. During imaging, reflection from shiny surfaces, such as greasy bone, disrupts image formation. This study tested the David SLS-1 scanner's ability to image saw marks and explored six strategies to reduce reflection by [1] dulling the surface or [2] altering the projected light. The surface was dulled by freezing, talcum powder, dulling spray, or compressed air. The projected light was altered with a diffuser or limited to single pattern-coded. Results demonstrated that the resolution was insufficient for capturing minute details of striae. All six tests failed to reduce reflection sufficiently to produce complete images, but projecting vertical pattern-coded light showed the most promise. Future research is required concentrating on enhancing resolution and exploring the role of pattern-coded light in reducing reflection.     

An Overview of 3D Printing in Forensic Science: The Tangible Third-Dimension

There has been a rapid development and utilization of three-dimensional (3D) printing technologies in engineering, health care, and dentistry. Like many technologies in overlapping disciplines, these techniques have proved to be useful and hence incorporated into the forensic sciences. Therefore, this paper describes how the potential of using 3D printing is being recognized within the various sub-disciplines of forensic science and suggests areas for future applications. For instance, the application can create a permanent record of an object or scene that can be used as demonstrative evidence, preserving the integrity of the actual object or scene. Likewise, 3D printing can help with the visualization of evidential spatial relationships within a scene and increase the understanding of complex terminology within a courtroom. However, while the application of 3D printing to forensic science is beneficial, currently there is limited research demonstrated in the literature and a lack of reporting skewing the visibility of the applications. Therefore, this article highlights the need to create good practice for 3D printing across the forensic science process, the need to develop accurate and admissible 3D printed models while exploring the techniques, accuracy and bias within the courtroom, and calls for the alignment of future research and agendas perhaps in the form of a specialist working group.     

The Analysis of 3D Printer Dust for Forensic Applications,,

3D printers are becoming increasingly efficient and economical, and thus more widespread and easily accessible to consumers and businesses. They have been used to print nefarious objects such as guns and suppressors. Previous research has documented the release of dust particles during the printing process; however, little has been written about the morphology and chemical features that define the dust emitted by these printers. This study was undertaken to recover, analyze, and identify the dust produced during the printing process in the context of forensic trace evidence analysis. Samples were collected from a variety of 3D fused deposition modeler printers, representing both consumer and commercial grade models. This work focused on printers that use thermoplastic filaments composed of acrylonitrile butadiene styrene (ABS) or polylactic acid (PLA), two of the most commonly used filament polymers. Swabs were used to collect dust within the printer chamber and then processed to isolate the dust particles. Particles produced from ABS filaments are most easily recognized via light microscopy through a combination of color, morphology, and fluorescence. The composition of these particles can be confirmed through analysis by either FTIR or Raman microspectroscopy. These methods can also be used to identify ABS fillers and pigments within the printer dust particles. In contrast, dust from PLA printers consistently contained finer, submicron-sized particles that could be observed by field emission scanning electron microscopy. Because the size of the particles precludes their identification using vibrational spectroscopy methods, pyrolysis-GC-MS was used to confirm the presence of PLA.     

Geomatic techniques in forensic science: A review

The purpose of this review paper is to highlight various geomatic techniques that crime scene reconstructionists or forensic practitioners can use to document different kinds of scenes, highlighting the advantages, disadvantages, and when best to use each technology. This paper explores geomatic techniques such as a total station, photogrammetry, laser scanners and structured light scanners and how they can be used to reconstruct crime scenes. The goal of this paper is not to discredit manual methods, as they are long standing and reliable, but instead to shed light on alternative methods that may produce equally or more accurate results with a more visually appealing final product. It is important for law enforcement and forensic professionals to understand the advantages and disadvantages of each technique, knowing when certain techniques should be used (and when they should not), and being able to revert to traditional methods if required.     

Senior Executives' Political Connections and Corporate Environmental Behavior—Empirical Research From the Chinese A‐Share Market

This thesis analyzed the cross‐section data of 630 non‐financial listed enterprises and adopts a logit model to estimate the relationships between political relations and corporate environmental behavior. The paper also adopts an ordered logit method to estimate the marginal impact of political connections to enterprises’ disclosure of information on environment and sustainable development. Through analysis, this thesis found that political connections lower the probability for enterprises to disclose information on environment and sustainable development. With the Level III scoring method, this article classified the performances of disclosing corporate environmental information into three levels. It is found that corporate political connections increase the probability for enterprises not to disclose any environmental information and lower the probability for enterprises to refer to GRI Sustainability Reporting Guidelines.     

Local Renewable Energy Initiatives in Germany and Japan in a Changing National Policy Environment

Our article explores the contribution of local initiatives to the creation of path dependencies for energy transition in Germany and Japan in the face of resistance from entrenched incumbents at the national level. We use a process‐tracing methodology based partly on interviews with local participants. In particular, we explore the role of local initiatives in securing “socio‐political space” for the expansion of renewable energy (RE) and in embedding themselves in “ecosystems” of public and private institutions. German energy activists were more successful than their Japanese counterparts in expanding this space and creating positive feedback in part because they were able to build horizontal networks that anchored the energy transition firmly in local communities. Although problems with grid technology have led to retrenchment in both cases, Japanese activists' reliance on vertical networks has limited their ability to weather a backlash from national government and utility actors. Our study demonstrates the interaction of political, economic/technological, and legitimation paths to energy transition and highlights the importance of the latter two.

10+3≠3+10:不同理论视域中的东亚区域合作

国际关系理论中的不同流派,由于看问题的视角不同,面对同一事物,其所看到的景象也不一样.对同一个以"10 3"为核心的东亚区域合作,建构主义学者看到的是其乐融融的规则建构景象,而现实主义学者看到的则是暗中较劲的权力之争.虽然有如此的不同,但二者对国家利益的强调,还是为我们调和二者的看法提供了线索.
