Political attitude estimation through Facebook like: a South Korean case study

Recently numerous studies are conducted to estimate the human personality from the online social activities. This paper develops a comprehensive model for political attitude estimation leveraging the Facebook Like information of the users. We designed a Facebook Crawler that efficiently collects data overcoming the difficulties in crawling Ajax enabled Facebook pages. We show that the category level selection can reduce the data analysis complexity utilizing the sparsity of the huge like-attitude matrix. In the Korean Facebook users’ context, only 28 criteria (3% of the total) can estimate the political polarity of the user with high accuracy (AUC of 0.82).     

中华民国矿场安全与健康立法的价值

民国时期,工业发展和长期战争急需矿产品而加速了矿业开发。但矿工的福利与迅速发展的矿业不协调,导致劳资双方对立。为此,国民政府制订了一系列改善矿工福利的法律法规,其中以《矿场法》最突出。该法是一部以健康安全优先、界定矿主责任、保障矿工权利、强制培训矿工的矿场安全与健康法。其立法目的、指导思想和基本原则很值得我们今天继承。     

从权利到工具:失效专利管理研究

失效专利是法律效力的丧失而非价值的丧失,通过价值评估及专利挖掘后完全可以将失去法律保护的这项权利转化为有力的工具,对失效专利进行事后管理可挖掘其剩余价值,促进产业进步。本文从失效专利的概念界定、失效原因及管理的必要性三方面出发,系统梳理和总结了学界关于失效专利管理的相关研究文献。研究发现,失效专利的管理主要围绕专利价值评估、专利申请与审查制度等因素展开。但当前研究在界定失效专利的定义及范围上并不统一,未形成明确的专利价值评估体系,也缺乏针对其管理的必要性分析。鉴于此,对失效专利进行管理需遵从以下路径:首先要厘清失效专利的定义并分析其失效原因,其次要总结失效专利管理的必要性及专利失效规律,最后从失效专利原权利人、相关市场企业以及政府部门等多主体视角出发提出管理对策,使失效专利管理秩序化、科学化。     

中国企业在发展中国家投资矿业的风险与应对策略

The Tax Reform Agenda in Australia

This paper applies concepts developed in the Policy Agendas Project (PAP) literature to an analysis of Australian tax policy over the post war period. It argues that a major turning point in the Australian tax policy agenda occurred during the second term of the Hawke Government (1984‐87). Beyond this turning point, and despite the fierce partisan conflict concerning tax policy over the past two decades, there has been remarkaly little difference between Australia's two major parties at the level of substantive policy content. The Australian tax policy agenda over the post war period can be characterised by remarkable policy continuity punctuated by a period of change in the mid 1980s when structural change in the international political economy precipitated unprecedented domestic liberalisation.     

从陕北煤矿生产现实状况看矿业权流转改革

矿业权流转制度的提出,在矿产资源市场化道路上迈出了一大步,但是我国矿产资源法对矿业权流转的相关规定依然存在一定局限性。适应我国市场经济体制改革的不断深化,充分发挥市场在资源配置方面的决定性作用,有必要进一步完善矿业权流转制度。矿业权流转市场体系的构建包括一级出让市场和二级转让市场。完善矿业权流转制度需要重视矿业权流转配套法规与技术性标准建设。     

Sino-Ghana bilateral relations and Chinese migrants’ illegal gold mining in Ghana

ABSTRACT

This article examines the participation of some Chinese migrants in illegal gold mining (known as galamsey) in Ghana, and how the Government’s policy to address the issue created diplomatic tension between China and Ghana. Drawing on primary data from in-depth, face-to-face interviews with 250 respondents and supplementary information from archival sources and personal observation, the study found that small-scale gold mining is an area legally reserved for Ghanaian indigenes, who faced stern competition from some Chinese migrants’ miners. Their ability to mobilize resources and machinery to execute galamsey virtually displaced the indigenes from their source of livelihood and caused environmental catastrophes. The Ghana Government’s policy response to the Chinese migrants’ galamsey, which led to arrests, sentencing and deportations of some Chinese miners, angered Beijing and fractured Ghana–China diplomatic ties. But the dispute could not collapse the entrenched bilateral relations between the two nations because the calculated mutual benefit derived from the relations was thought to be higher than the Chinese galamsey issue. Policy reforms which legally integrate Chinese migrants’ miners into the small-scale mining sector would stop galamsey and strengthen Sino-Ghana relations.     

Permanent precarity: capital and labour in the Central African copperbelt

Abstract

This article provides a new history of mine capital and labour in the ‘Central African Copperbelt’ – the cross-border mining region of the Zambian copperbelt and Haut Katanga in the Democratic Republic of Congo. It doing so, it seeks to overcome the limitations of earlier structurally minded analysis rooted in modernist notions regarding the transformative capacity of mining capital and a ‘new’ African working class. Building on post-structuralist challenges to such assumptions, the article demonstrates the precarity, unevenness and uncertainty of the actually existing copperbelt economy and society. The comparison of the two copperbelt regions enables consideration of differential outcomes as a way of rethinking apparent inevitabilities. Analysis of how ideas about these mining societies were generated and circulated helps explain how dominant ways of understanding copperbelt capital and labour relations became established and continue to inform nostalgia for a ‘golden age’ of mining-fuelled prosperity at odds with historical reality.     

论工会在矿业集体合同中的定位

矿山工会通过集体讨价还价与企业订立硅康安全方面的行业性专项集体合同，是工会为集团成员提供的非排他性集体物品。不完全性健康安全专项合同的剩余控制权不是处于公共领域，而是由矿方控制，因而保证不完全合同的实施是矿山工会的核心任务。专项集体合同有效履行，能内化矿方应投人工作场所健康安全的成本，以改变矿方与矿工在初次分配中的收入。矿方会竭力阻碍减损其收益的制度变迁，市场失灵时依法组织罢工是订立和履行合同的最后手段。这需要进一步解放思想，完善宪法原则。     

论数据挖掘在预防小区犯罪中的应用

数据挖掘是指从数据库或数据仓库中提取隐含的、未知的及有潜在应用价值的信息或模式。数据挖掘技术应用于预防小区犯罪,采用CRISP-DM方法论,通过数据理解、数据准备、模型选择、建立模型、训练模型、评估模型等流程,可以对犯罪分布区域、犯罪分子惯用手段、犯罪行为特征、受害人特征、受害人群识别等进行分析,识别高犯罪率的小区及犯罪特征。
