Chinese Indonesians After May 1998 How They Fit in the Big Picture

For Chinese Indonesians, May 1998 is a significant historical marker, twelfth and thirteenth being two concentrated days of riots and atrocities in Jakarta, followed by more, albeit on smaller scales, in Solo, Surabaya, and a number of other cities. Destruction of properties belonging to them, and rapes of their women, occurred. Then Indonesia witnessed the end of Suharto\u27s rule when the president resigned on 21 May 1998. A gradual political turn-around followed; Chinese Indonesians found room to move. The subsequent governments revoked restrictive regulations put in place by the New Order government, and lifted the suppression on cultural expression by Chinese Indonesians. The situation has progressed in conjunction with China\u27s rise in global economic dominance. Does China\u27s increasing International profile and rising global economic dominance help Chinese Indonesians? This article seeks to find some answer to the question as it looks at the development in the big picture; how and to what extent the social perceptions of Chinese Indonesians have evolved among the mainstream population; how they perceive themselves and believe how others perceive them; and how these may influence their lives as Indonesian citizens

Managed Care’s Crimea: Medical Necessity, Therapeutic Benefit, and the Goals of Administrative Process in Health Insurance

En brotyp som är vanlig bland brokonstruktioner är plattrambron. Denna brotyp byggs både med slak- och spännarmering. Det är dock vanligare att bygga med slakarmering än spännarmering, vilket övervägs särskilt då spännvidderna är ungefär 25- 30 meter eller mer. Inledningsvis har en noggrann litteraturstudie genomförts tillsammans med en intervju av en kunnig brokonstruktör för att säkerställa en interaktion mellan teori och aktuell praxis. Detta arbete har haft ett huvudmål, vilket är att ur ett struktur- och kostnadsperspektiv jämföra och utvärdera hur behovet av slakarmering varierar i en plattrambros farbana då spännvidder varieras och betongtvärsnitt ändras. Arbetet har utförts med hjälp av finita elementprogrammet ”Brigade Standard”, vilket erbjuder en tre-dimensionell strukturanalys. Fyra olika tvärsnitt för spännvidder mellan 10-20 meter analyseras. Dimensioner på brodelar bestäms med hjälp av tumregler samt generella råd från intervjuperson; höjd i fält enligt L/20, L/25, L/30 samt L/35, där L är spännvidden. Resultatet visar främst att för ökade spännvidder mot 20 meter ökar lasteffekten på grund av egentyngd drastiskt och då särskilt det tvärsnitt som är störst, det vill säga L/20. Vidare visas även att slankare tvärsnitt resulterar i aningen högre armeringsmängd. Dock påverkas betongkostnaden i större utsträckning av slankare tvärsnitt och särskilt större spännvidder. Även om större spännvidd och slankare tvärsnitt föranleder ett större armeringsbehov, fås en lägre totalkostnad. Det bör noteras att priset på betong och stål är starkt beroende av konjunktur och tillgång till material. Denna studie kan bli ännu intressantare då priset varierar kraftigt för stål och föranleder att betongpriset blir mindre dominerande än vad det är idag. Huvudprodukten från detta arbete är att med hjälp av tabeller och nya priser kunna beräkna en preliminär totalkostnad för plattrambrons farbana för olika spännvidder och hur olika tvärsnittsalternativ påverkar denna kostnad

Inquiring the usage of aspect-oriented programming: an empirical study

International audienceBack in 2001, the MIT announced aspect-orientedprogramming as a key technology in the next 10 years.Nowadays, 8 years later, AOP is not widely adopted.Several reasons can explain this distrust in front ofAOP, and one of them is the lack of robust tools foranalysis, testing and maintenance. In order to developdedicated solutions for assisting the development withAOP, and increase its adoption, we need to understandhow it is actually used. In this paper we analyze 38aspect-oriented open source projects with respect tothe impact of aspects on the projects, and to coverageof the language features. This reveals that AOP iscurrently used in a cautious way. This work is a firststep to built support and development tools dedicatedto actual practices for AOP, based on empirical usage profiles

Extensibility of Enterprise Modelling Languages

Die Arbeit adressiert insgesamt drei Forschungsschwerpunkte. Der erste Schwerpunkt setzt sich mit zu entwickelnden BPMN-Erweiterungen auseinander und stellt deren methodische Implikationen im Rahmen der bestehenden Sprachstandards dar. Dies umfasst zum einen ganz konkrete Spracherweiterungen wie z. B. BPMN4CP, eine BPMN-Erweiterung zur multi-perspektivischen Modellierung von klinischen Behandlungspfaden. Zum anderen betrifft dieser Teil auch modellierungsmethodische Konsequenzen, um parallel sowohl die zugrunde liegende Sprache (d. h. das BPMN-Metamodell) als auch die Methode zur Erweiterungsentwicklung zu verbessern und somit den festgestellten Unzulänglichkeiten zu begegnen. Der zweite Schwerpunkt adressiert die Untersuchung von sprachunabhängigen Fragen der Erweiterbarkeit, welche sich entweder während der Bearbeitung des ersten Teils ergeben haben oder aus dessen Ergebnissen induktiv geschlossen wurden. Der Forschungsschwerpunkt fokussiert dabei insbesondere eine Konsolidierung bestehender Terminologien, die Beschreibung generisch anwendbarer Erweiterungsmechanismen sowie die nutzerorientierte Analyse eines potentiellen Erweiterungsbedarfs. Dieser Teil bereitet somit die Entwicklung einer generischen Erweiterungsmethode grundlegend vor. Hierzu zählt auch die fundamentale Auseinandersetzung mit Unternehmensmodellierungssprachen generell, da nur eine ganzheitliche, widerspruchsfreie und integrierte Sprachdefinition Erweiterungen überhaupt ermöglichen und gelingen lassen kann. Dies betrifft beispielsweise die Spezifikation der intendierten Semantik einer Sprache

Automated Test Input Generation for Android: Are We There Yet?

Mobile applications, often simply called "apps", are increasingly widespread, and we use them daily to perform a number of activities. Like all software, apps must be adequately tested to gain confidence that they behave correctly. Therefore, in recent years, researchers and practitioners alike have begun to investigate ways to automate apps testing. In particular, because of Android's open source nature and its large share of the market, a great deal of research has been performed on input generation techniques for apps that run on the Android operating systems. At this point in time, there are in fact a number of such techniques in the literature, which differ in the way they generate inputs, the strategy they use to explore the behavior of the app under test, and the specific heuristics they use. To better understand the strengths and weaknesses of these existing approaches, and get general insight on ways they could be made more effective, in this paper we perform a thorough comparison of the main existing test input generation tools for Android. In our comparison, we evaluate the effectiveness of these tools, and their corresponding techniques, according to four metrics: code coverage, ability to detect faults, ability to work on multiple platforms, and ease of use. Our results provide a clear picture of the state of the art in input generation for Android apps and identify future research directions that, if suitably investigated, could lead to more effective and efficient testing tools for Android

Object-Centric Reflection: Unifying Reflection and Bringing It Back to Objects

Reflective applications are able to query and manipulate the structure and behavior of a running system. This is essential for highly dynamic software that needs to interact with objects whose structure and behavior are not known when the application is written. Software analysis tools, like debuggers, are a typical example. Oddly, although reflection essentially concerns run-time entities, reflective applications tend to focus on static abstractions, like classes and methods, rather than objects. This is phenomenon we call the object paradox, which makes developers less effective by drawing their attention away from run-time objects. To counteract this phenomenon, we propose a purely object-centric approach to reflection. Reflective mechanisms provide object-specific capabilities as another feature. Object-centric reflection proposes to turn this around and put object-specific capabilities as the central reflection mechanism. This change in the reflection architecture allows a unification of various reflection mechanisms and a solution to the object paradox. We introduce Bifr\"ost, an object-centric reflective system based on first-class meta-objects. Through a series of practical examples we demonstrate how object-centric reflection mitigates the object paradox by avoiding the need to reflect on static abstractions. We survey existing approaches to reflection to establish key requirements in the domain, and we show that an object-centric approach simplifies the meta-level and allows a unification of the reflection field. We demonstrate how development itself is enhanced with this new approach: talents are dynamically composable units of reuse, and object-centric debugging prevents the object paradox when debugging. We also demonstrate how software analysis is benefited by object-centric reflection with Chameleon, a framework for building object-centric analysis tools and MetaSpy, a domain-specific profile

A comparative analysis of recommender systems based on item aspect opinions extracted from user reviews

In popular applications such as e-commerce sites and social media, users provide online reviews giving personal opinions about a wide array of items, such as products, services and people. These reviews are usually in the form of free text, and represent a rich source of information about the users’ preferences. Among the information elements that can be extracted from reviews, opinions about particular item aspects (i.e., characteristics, attributes or components) have been shown to be effective for user modeling and personalized recommendation. In this paper, we investigate the aspect-based recommendation problem by separately addressing three tasks, namely identifying references to item aspects in user reviews, classifying the sentiment orientation of the opinions about such aspects in the reviews, and exploiting the extracted aspect opinion information to provide enhanced recommendations. Differently to previous work, we integrate and empirically evaluate several state-of-the-art and novel methods for each of the above tasks. We conduct extensive experiments on standard datasets and several domains, analyzing distinct recommendation quality metrics and characteristics of the datasets, domains and extracted aspects. As a result of our investigation, we not only derive conclusions about which combination of methods is most appropriate according to the above issues, but also provide a number of valuable resources for opinion mining and recommendation purposes, such as domain aspect vocabularies and domain-dependent, aspect-level lexiconsThis work was supported by the Spanish Ministry of Economy, Industry and Competitiveness (TIN2016-80630-P)
