APK Auditor: Permission-based Android malware detection system

Android operating system has the highest market share in 2014; making it the most widely used mobile operating system in the world. This fact makes Android users the biggest target group for malware developers. Trend analyses show large increase in mobile malware targeting the Android platform. Android's security mechanism is based on an instrument that informs users about which permissions the application needs to be granted before installing them. This permission system provides an overview of the application and may help gain awareness about the risks. However, we do not have enough information to conclude that standard users read or digital investigators understand these permissions and their implications. Digital investigators need to be on the alert for the presence of malware when examining Android devices, and can benefit from supporting tools that help them understand the capabilities of such malicious code. This paper presents a permission-based Android malware detection system, APK Auditor that uses static analysis to characterize and classify Android applications as benign or malicious. APK Auditor consists of three components: (1) A signature database to store extracted information about applications and analysis results, (2) an Android client which is used by end-users to grant application analysis requests, and (3) a central server responsible for communicating with both signature database and smartphone client and managing whole analysis process. To test system performance, 8762 applications in total, 1853 benign applications from Google's Play Store and 6909 malicious applications from different sources were collected and analyzed by the system developed. The results show that APK Auditor is able to detect most well-known malwares and highlights the ones with a potential in approximately 88% accuracy with a 0.925 specificity.     

砂拉越华族族群母语教育与文化传承的维护:以古晋中华第一中学之兴办为个案研究

砂拉越位于婆罗洲,原为文莱属地,1841年白人拉惹政权建立后,大批华人在其招垦下移入砂拉越。在华文教育萌芽的初期,白人拉惹对其取自由放任的态度,直至20世纪20年代,因华人社会中的政治运动及海外华侨民族主义在各个华文学校的发展,才颁布学校注册法令,开始干涉砂拉越地区的华文教育。二战后,白人拉惹将砂拉越让渡给英国,新成立的殖民地政府急于统合境内各族群对砂拉越的认同,遂推动以英语为教学媒介语的国家教育制度,迫使砂拉越华文中等学校在改制成以英语授课的学校或独立中学之间做出选择。为保存族群母语教育,为华族子弟接受母语教育提供机会,在古晋地区创立的中华第一中学,决定成为一间华文独立中学。这间华文独立中学至今仍有千名以上学生,其校园中充满华族文化气息。本文对古晋中华第一中学的创立、发展、经营作一个案研究,期盼对吾人进一步了解战后砂拉越华族社会族群语言的维护及文化的传承有所助益。     

党员身份认同与中国特色社会主义事业主体意识的自觉

党员身份是党员内化党章、准则、政治信念和价值系统等为自我思想体系并进行自我认知和确认的独特标识,是新时期对中国特色社会主义事业实现主体的事实或理论概括,身份管理是其力量生成和团结的思想和观念基础。自从中国共产党成立以来,党员身份从起初的信念约束状态到阶级属性再到政治身份管理过程,呈现出不同阶段自我管理的具体形式。从主体意识、现实经验来看,新时代中国特色社会主义事业主体沿着"我是共产党员、真正懂得中国特色社会主义思想的共产党员、正确对待中国特色社会主义实践的共产党员"等路径形成和发展身份认同,是团结一切力量和保证"党的在场"的关键所在,对于实现"第二个百年"奋斗目标具有重大理论价值和实践意义。     

中国大一统的历史密码破译——基于政治经济制度的阐释

中国 “大一统”国家形态的形成源于治理水患与抵御外敌所需要的国家管理能力，而其维持则需要适应性的政治经济制度设计以维持中央政权的全面掌控能力。在农业社会，国家的控制能力取决于有效的组织体系与稳定的土地税收。为此，中国历代政权经过长期调整形成了以科举制为选拔机制的核心政治密码及建立有效土地制度和税收制度的经济密码。科举制能够更多地促进社会阶层的有序流动，延缓了侵占国家权力与土地税收的大地主的崛起，而土地制度虽然为适应人口及生产状况最终走向了私有制为主的道路，但在科举制确立以后的土地兼并再未形成影响国家行政能力的门阀地主阶层，从而有效地维持了国家的统一。因此，有序社会流动与土地税收制度设计正是保持历史上中国大一统的核心政治、经济密码。     

政府治理成本与公民满意:内在联系与成本控制

政府治理成本支出的高效化是政府治理的核心,也是公民满意的必要条件,而公民满意有利于政府治理成本的高效化,二者内在关系紧密。中国政府治理成本控制压力加大,政府治理有效性与公民需求存在一定差距,而广大人民对政府治理效能的期望不断提高,政府必须要树立善治理念,提高政府治理能力,遏制扩大治理成本的原始动机;树立人民至上的服务观念,科学决策和制定政策,遏制制度性成本;树立质量观念,不断提高公共产品与服务的供给质量;树立公平与共享理念,充分发挥公共财政调节机制,健全政府成本会计体系,增强人民的获得感和满意度,提高政府治理成本支出的有效性。     

Governance and Regulation of the Peruvian University System: Overcoming Reform Resistance through Quality Assurance Policies

This article examines the new governance of the Peruvian university system, which evolved in response to market liberalisation and weak quality assurance mechanisms. New actors and commercial interests emerged, building their network of relationships within the political arena. With the passing of a new Universities Law in 2014, ambitious reforms were set in motion, designed to reverse the decline in the quality of higher education. This study examines these reforms, focusing on whether and how they are changing the governance and structure of the system. It also identifies some conceptual and design flaws, such as the weaknesses of the main steering body and the accreditation regime, as well as limitations on the independence of the regulatory agency.     

都市生态治理中党政干部领导力探讨

推进都市生态治理是促进区域经济社会协调可持续发展的应有之义。本文以A省S市都市生态治理中党政干部领导力为基点,阐释了S市党政干部在生态治理中发挥的核心作用,同时也发现其中面临领导动力弱化、领导效益损耗、领导协同失效、领导制度选择性执行等困局。因此,应从增强都市生态治理中党政干部领导自洽力、提升领导转换力、激活领导制度力、培育领导协同力、厚植内生领导力等方面寻求破解之道。     

新冠肺炎疫情与全球安全文化的退化

安全文化是一个社群就怎样界定安全和安全威胁、怎样保障和实现安全所达成的主体间理解和共同知识。冷战之后,全球化推动了一个全球社会的初步形成,因之也催生了一种以开放安全、共同安全与合作安全为基本内容的合作型全球安全文化的雏形。但是由于全球治理失灵,不断出现且日益积累的全球性威胁得不到有效应对,民粹现实主义强势兴起,合作型全球安全文化屡遭重创,开始向以封闭安全、孤立安全、零和安全的冲突型安全文化转变,明显降低了国际安全合作的几率。抗击新冠肺炎疫情中的全球公共安全合作的失败就是一个明显的例证。虽然人类向共同体进化的历史大趋势不可阻挡,但在一段时间内,合作型全球安全文化与冲突型全球安全文化的激烈竞争将会是国际关系的新常态。     

From boomerangs to minefields and catapults: dynamics of trans-local resistance to land-grabs

This paper explores the political processes that activists engaged in contesting land grabbing have triggered to connect claims across borders and to international institutions, regimes and processes. Through a review of cases of land-grab resistance that have led to project cancelation or suspension, I argue that contextual elements of the land grab and shifting geopolitics highlight the need for adaptation and refinement of models of transnational advocacy, historically structured in North–South patterns. For example, while some elements of the boomerang pattern of transnational advocacy are still relevant, changing realities call for new empirically enriched models. To this end, I outline two typologies of political contention that can help us conceptualize multi-scalar interactions between activists to demonstrate the impact of local resistances at larger scales – ‘the catapult effect’ and the ‘minefield effect’. This paper contributes to calls for further theorization to understand how feedback processes between international discourses, meso-politics and conflicts and resistance at local sites of production impact the implementation of contested land deals.     

网络问政的政府回应逻辑：公开承诺压力与选择性回应——基于66个政府网站领导信箱的实验设计

立足我国制度环境与行政体制，建构了网络问政领导信箱回应运行理论框架，提出影响回应绩效五个影响因素，包括行政系统区域特点与领导者特质两个内部因素，外部因素包括政治压力、舆论压力及诉求压力三个维度。采用德尔菲法建构了领导信箱回应绩效指标体系，并采用实验设计搜集66个领导信箱网络问政回应的有效样本。实证结果显示：政治压力中的公开承诺程度对回应绩效有正向效应，诉求压力中的诉求类别对回应绩效有显著影响，政府回应存在“选择性回应”问题。为了进一步提升政府网站领导信箱的回应绩效，可以完善内部回应流程、公开对外服务承诺与建立自下而上回应性问责机制。
