我国光污染防治立法初探

光污染是继废气、废水、废渣和噪声污染之后的一种新的环境污染,其对环境的危害日益严重。我国光污染的严重现状及法律规制的不足使我国有必要进行光污染防治立法。我们应当以经济、生态的可持续发展为指导理念,制定一部光污染的单行法,建立光环境标准制度、光污染防治管理制度、公众参与制度、当事人责任分担制度等对其进行规制。     

Small arms and light weapons: the disjunction problem

ABSTRACT

Growing in range and urgency, humanitarian needs now pose increasingly acute questions for national security policy formulation. Whether over forced migration, food scarcity or nefarious electronic penetration, state security preferences face uneasy accommodations with individual needs be it for child survival, basic sustenance or rights to privacy. This paper deliberates a further field of increasingly apparent value contest: that involving the transfer, diversion and lethal use of small arms and light weapons (SALW). After outlining the scale of this phenomenon, existing regulatory mechanisms over SALW transfers are assessed. It is argued that these controls are inadequate, a deficiency that is embedded within a range of inter-linked disjunctions. They are outlined in a model that is evaluated against empirical findings. Where SALW control inadequacy is causally connected to the disjunctive model, it is argued, current levels of SALW-induced casualties are unlikely to abate. The paper concludes by considering feasible options for enhanced management of global SALW proliferation.     

Determining Line-Crossing Sequences Between Laser Printing and Writing Pen Using Coaxial Light

Determining the application sequence of hand-written pen ink and printer toner lines has attracted significant interest in questioned document examination. This study uses coaxial light to determine line-crossing sequences, with intersections observed under a VSC600 forensic document workstation and a Leica M205A Stereo-microscope. Results show that reflected light at intersections and color contrast between intersections and nonintersections was observed when a hand-written ink line passes over a toner line, while a toner line passing over a written line appeared dull, with no color contrast. The procedure was tested under a range of conditions, such as types of writing pens and laser printers, the writer, and writing pressure, with the latter playing an important role in the evaluation. To validate the results, a 90% detection rate and 98% accuracy rate were achieved from 50 samples of blind testing, which is more effective than optical microscopy.     

Racial attitudes & political cross-pressures in nationalized elections: The case of the Republican coalition in the Trump era

While scholars have found that Trump was able to capitalize on the racial attitudes of white voters, it is less clear how these racial attitudes influenced vote-choice across partisan and ideological cleavages in the electorate. It is also unclear whether racial attitudes affected voting at the congressional level or electoral outcomes at the aggregate level. Using a novel measure of racial attitudes at the subnational level and survey data, we make three clear findings: (1) Trump and Republican congressional candidates benefited from conservative racial attitudes both at the aggregate level and among white voters, (2) this electoral benefit for Republicans persisted during the 2018 midterm elections, and (3) the effect of attitudes on vote-choice did not significantly vary across partisan and ideological cleavages in the white electorate. Our findings suggest that, even during the era of highly nationalized and partisan elections, racial attitudes are still a mechanism by which Republicans can win significant electoral support among Democrats and relatively liberal voters in the white electorate. These findings have implications for the growing salience of race in the Republican electoral coalition.

The Development of Competitive Industries: The Role of State Government Actors

Despite widespread adoption of Porter's Industrial Cluster Theory as a policy development framework by federal and state governments over the past decade, Australia remains significantly below the OECD average in terms of its industries' economic contributions to real wealth creation ( Brown 2000 ; OECD 1998 ). The major cause cited for this relatively poor performance has been inability of key government officials to implement effective industry policy that simultaneously avoids de facto protectionism and distortion of competition. This article provides an insight into the key policy decisions undertaken by the Tasmanian state government that coincided with development of an internationally successful shipbuilding industry in that state. As such, this article provides a reflection on policy initiatives that may be valuable for government officials elsewhere.     

中国古代慎刑的政治思想

慎刑是我国古代社会世轻世重刑事政策的重要内容，它的推行受了多重政治思想的影响。正是由于秦朝法家重刑主义思想的惨败、西汉初期黄老道家思想的推行、汉代以后儒家政治思想的一以贯之，统治者在刑罚的适用中才秉承了慎刑思想，进而建立起了容隐、怜老恤幼、死刑审核等慎刑制度。
