Java's forgotten pearls: the history and disappearance of pearl fishing in the Segara Anakan lagoon, South Java, Indonesia

Pearls have been a valued resource in most cultures that had access to them. A number of historically important pearling grounds were situated in the waters around today's Indonesia. One of these areas, now largely forgotten, was the Segara Anakan lagoon in South Java. In the seventeenth century, Dutch colonists exploited the lagoon's pearls. Afterwards, the lagoon's oysters were locally exploited as a food item until the late 1970s. While the pearl fishery attracted considerable attention in the colonial literature, its disappearance, by contrast, went largely undocumented. Nowadays, the oysters no longer are found in the lagoon as a result of extensive sedimentation processes. Their former existence is only preserved in the memory of local people. This article examines the history and fate of the pearls of Segara Anakan, providing an example of a formerly valued species whose existence simply became forgotten outside the area.     

四川区域中心馆藏文物保存环境监测平台常见故障分析与改进措施

四川省馆藏文物保存环境监测区域中心(简称四川区域中心)平台,经过两年多的运行实践,实现了12家博物馆监测站的集成联网。本研究分析了区域中心监测平台运行中常见故障现象的表现形式、故障原因及故障率。结果表明:监测平台的主要故障现象为传输异常和数据异常;除温湿度外的其他监测终端故障率较高;软件平台建设也不够完善,导致数据利用率低,尚不能实现风险评估、预测预警和预防调控等管理功能。针对分析发现的问题,提出一些相应的技术措施和管理措施,为有效降低故障的发生率,提升国内区域中心平台建设提供一定的指导和参考。     

The executive lawmaking agenda: Political parties,prime ministers,and policy change in Australia

In Westminster systems, governments enjoy a privileged position in the lawmaking process that they can use to deliver on their campaign promises and achieve their policy goals. What policy areas do governments seek to affect through lawmaking? How stable is the executive lawmaking agenda? How responsive is that agenda to changes triggered by elections or by transitions in prime minister? This study uses a dataset of 3982 Australian bills introduced between 2000 and 2017 to answer these questions. While it finds considerable stability in the policy content of executive lawmaking agendas, the analysis also indicates that Australia's executive lawmaking agenda is more responsive to changes in prime minister than to changes in the party in power. As the first application of the comparative policy agendas approaches to government bills in Australia, this article offers new insights into executive lawmaking priorities during an especially turbulent period in Australian politics.     

Adaptive strategies or ideological innovations? Interpreting sociopolitical developments in the Jequetepeque Valley of Peru during the Late Moche Period

Environmental perturbations and social unrest are thought to have led to the reconstitution of traditional belief systems and hierarchical political relations on Peru’s North Coast during the Late Moche Period (550–800 AD). Ideological transformations are thus commonly interpreted as adaptive or reactive responses to social, political, and ecological disruptions. Nevertheless, religious practices directly shaped the formation of alternative power structures and ecological systems on the North Coast during the Late Moche Period. This is especially evident in Late Moche Jequetepeque, which witnessed the proliferation of non-elite ceremonial sites and small-scale agricultural facilities throughout the rural hinterland of the valley. Moche-inspired ritual performances orchestrated in the countryside created distinctive new forms of political order which structured economic activities and ecological behavior. In this article, the Jequetepeque case study is mobilized to reassess normative interpretations of the role of religious ideology in cultural adaptation and sociopolitical realignment.

Playing Politics with Sex Offender Laws: An Event History Analysis of the Initial Community Notification Laws across American States

Despite a decline in crime rates, the 1990s witnessed extensive media coverage of several high‐profile stranger abductions and murders of children. State legislators' swift response to the public's growing fear of sex offenders with the adoption of sex offender registration and notification (SORN) laws raises questions about the role of politics. Punctuated equilibrium theory and the diffusion of innovation jointly provide a context to conduct an event history analysis to assess the extent to which politics enhanced legislative responsiveness to public opinion in SORN policymaking. Contrary to the commonly held belief that attributes legislative interest in SORN to salient crimes against children, the results suggest that factors such as the percentage of a conservative population, district‐level competition, and state innovativeness accelerated the diffusion of innovation of the laws.     

The Importance of Attention Diversity and How to Measure It

Studies of political attention often focus on attention to a single issue, such as front‐page coverage of the economy. However, examining attention to a single issue without accounting for the agenda as a whole can lead to faulty assumptions. One solution is to consider the diversity of attention; that is, how narrowly or widely attention is distributed across items (e.g., issues on an agenda or, at a lower level, frames in an issue debate). Attention diversity is an important variable in its own right, offering insight into how agendas vary in their accessibility to policy problems and perspectives. Yet despite the importance of attention diversity, we lack a standard for how best to measure it. This paper focuses on the four most commonly used measures: the inverse Herfindahl Index, Shannon's H, and their normalized versions. We discuss the purposes of these measures and compare them through simulations and using three real‐world datasets. We conclude that both Shannon's H and its normalized form are better measures, minimizing the danger of spurious findings that could result from the less sensitive Herfindahl measures. The choice between the Shannon's H measures should be made based on whether variance in the total number of possible items (e.g., issues) is meaningful.     

故宫古建筑内温湿度问题初探

博物馆的环境应当相对稳定且有益于文物的保存。故宫博物院作为古建筑博物馆,其特殊性在于古建筑本身也是文物,虽然自身条件较差,但又不能随意改变其外观和结构,导致其保存环境往往不够理想。在研究中论述了故宫古建筑的环境特点,结合在古建筑内文物环境监测和控制方面的若干问题进行有益的探讨,对原状陈列的古建筑温湿度调控的应用效果进行了分析和评估,指出了存在的问题,并提出了对古建筑中环境控制的思考。采用密封性能优良的展柜配合适当的调湿材料可以很好地稳定相对湿度,减少温度变化对相对湿度造成的影响,这是当前国际上文物微环境控制的一个发展方向。     

The "Mouse That Roared": Agenda Setting in Canadian Pesticides Politics

Issue redefinition and venue shopping have been identified as key strategies for enacting agenda and policy change, but much work remains to be done in elaborating these processes. I argue that an important aspect of issue redefinition involves shifting not only the image of an issue but also the bases for considering those issues—what I call policy principles. Policy principles are the core values, beliefs, or guidelines attached to policies that help direct decision making. The emergence and acceptance of new principles by the public and policymakers can be a vital source of policy change, at times having far greater consequences for policy than redefining an issue. Venue shopping is also a multifaceted undertaking involving efforts by policy entrepreneurs and advocacy groups to keep issues out of venues they would rather not participate in as well as move decision making to new arenas. Moreover, while the literature suggests that shifting venues is usually a sensible strategy, sometimes venue shopping can backfire. A case study of the municipal movement to restrict the nonessential use of lawn and garden pesticides in Canada illustrates these theoretical points and shows the applicability of agenda setting models to contexts outside the United States.     

Sexual citizenship in ‘the New Tasmania’

The state of Tasmania, the smallest in the Commonwealth of Australia, has recently reformed its law relating to relationships by amending over 100 pieces of legislation to include a range of relationships, including lesbian and gay partnerships, among those given recognition and legal entitlement. This government-sponsored legislation is represented as central to the program of economic revival, social reform and branding described as ‘the New Tasmania’. This article locates the relationship reform in this discourse of Tasmania's newness and in the context of neo-liberal approaches to globalisation. It argues that sexual citizenship takes a multitude of forms and its value, like the value of relationship reform legislation, cannot be easily determined. Indeed, it asks whether sexual citizenship as a form of belonging can ever be disentangled from the various contexts where it is performed. It concludes by privileging the desires and performances of sexual citizenship over the constitution of sexual citizenship in rights or recognition.
