Rethinking privacy in social networks: A case study of beacon

Popular online social network sites (SNS) such as Facebook and Bebo are technological platforms that are posing questions about personal privacy. This paper contributes to our understanding of the nature and form of online privacy by critically analysing the issues surrounding the failed launch of Facebook’s advertising tool Beacon. Beacon is an interesting case study because it highlighted the complexity of information ownership in an online social network. Qualitative data was gathered from 29 weblogs (blogs) representing user opinions published between 6th November 2007(when Beacon was launched) and 28th February 2008 (when commentary had dwindled). A thematic analysis of the blogs suggest that concerns such as commercialism, terms of service (TOS), lack of user control, lack of user awareness and data protection are factors that influence user perceptions of information ownership as a subset of online privacy

Mining social network data for personalisation and privacy concerns: A case study of Facebook’s Beacon

This is the post-print version of the final published paper that is available from the link below.The popular success of online social networking sites (SNS) such as Facebook is a hugely tempting resource of data mining for businesses engaged in personalised marketing. The use of personal information, willingly shared between online friends' networks intuitively appears to be a natural extension of current advertising strategies such as word-of-mouth and viral marketing. However, the use of SNS data for personalised marketing has provoked outrage amongst SNS users and radically highlighted the issue of privacy concern. This paper inverts the traditional approach to personalisation by conceptualising the limits of data mining in social networks using privacy concern as the guide. A qualitative investigation of 95 blogs containing 568 comments was collected during the failed launch of Beacon, a third party marketing initiative by Facebook. Thematic analysis resulted in the development of taxonomy of privacy concerns which offers a concrete means for online businesses to better understand SNS business landscape - especially with regard to the limits of the use and acceptance of personalised marketing in social networks

Circular frame fixation for calcaneal fractures risks injury to the medial neurovascular structures: a cadaveric description

Aim: There is a risk of iatrogenic injury to the soft tissues of the calcaneus and this study assesses the risk of injury to these structures in circular frame calcaneal fracture fixation. Materials and Methods: After olive tip wires were inserted, an L-shaped incision on the lateral and medial aspects of 5 formalin fixed cadaveric feet was performed to expose the underlying soft tissues. The calcaneus was divided into zones corresponding to high, medium and low risk using a grading system. Results: Structures at high risk included the posterior tibial artery, posterior tibial vein and posterior tibial nerve on the medial aspect. Soft tissue structures on the lateral side that were shown to be at lower risk of injury were the small saphenous vein and the sural nerve and the tendons of fibularis longus and fibularis brevis. Conclusion: The lateral surface of the calcaneus provides a lower risk area for external fixation. The risk of injury to significant soft tissues using a circular frame fixation approach has been shown to be greater on the medial aspect. Clinical Relevance: This study highlights the relevant anatomical relations in circular frame fixation for calcaneal fractures to minimize damage to these structures

Improving route discovery in on-demand routing protocols using local topology information in MANETs

Most existing routing protocols proposed for MANETs use flooding as a broadcast technique for the propagation of network control packets; a particular example of this is the dissemination of route requests (RREQs), which facilitate route discovery. In flooding, each mobile node rebroadcasts received packets, which, in this manner, are propagated network-wide with considerable overhead. This paper improves on the performance of existing routing protocols by reducing the communication overhead incurred during the route discovery process by implementing a new broadcast algorithm called the adjusted probabilistic flooding on the Ad-Hoc on Demand Distance Vector (AODV) protocol. AODV [3] is a well-known and widely studied algorithm which has been shown over the past few years to maintain an overall lower routing overhead compared to traditional proactive schemes, even though it uses flooding to propagate RREQs. Our results, as presented in this paper, reveal that equipping AODV with fixed and adjusted probabilistic flooding, instead, helps reduce the overhead of the route discovery process whilst maintaining comparable performance levels in terms of saved rebroadcasts and reachability as achieved by conventional AODV\@. Moreover, the results indicate that the adjusted probabilistic technique results in better performance compared to the fixed one for both of these metrics

ANALISIS TINGKAT KAPASITAS DAN KERENTANAN PEREMPUAN DALAM UPAYA PENGURANGAN RISIKO BENCANA TSUNAMI DI WILAYAH PESISI KECAMATAN PEUKAN BADA KABUPATEN ACEH BESAR

ABSTRAKKecamatan Peukan Bada merupakan salah satu kecamatan di Kabupaten AcehBesar yang terkena dampak bencana tsunami 2004 sangat parah, terutama diGampong Lamteh, Gampong Baro dan Gampong Lamteungoh yang menjadilokasi penelitian ini. Secara geografis, ketiga lokasi penelitian ini berada padawilayah pesisir yang berpotensi terkena dampak bencana tsunami di masa yangakan datang. Tujuan penelitian ini adalah untuk menganalisis tingkat kapasitasdan kerentanan perempuan, menganalisis pengaruh faktor demografi terhadapkapasitas dan kerentanan serta menganalisis strategi untuk meningkatkankapasitas serta mengurangi kerentanan perempuan dalam upaya penguranganrisiko bencana tsunami di wilayah pesisir Kecamatan Peukan Bada Aceh Besar.Penelitian ini menggunakan metode penelitian kombinasi (mixed methods) yaitudenganmenggunakan pendekatan data gabungan kuantitatif dan kualitatif. Sampelpenelitian terdiri dari 81 orang perempuan yang ditentukan denganmenggunakanmetode survey dengan teknik Quota Sampling. Data primer diperoleh melaluikuesioner kepada responden dan wawancara terstruktur dengan 6 orang informanyang bermukim di tiga gampong lokasi penelitian. Data sekunder diperoleh daridokumentasi Keuchik dan data dari Badan Pusat Statistik (BPS) Aceh Besar.Kuesioner disusun dengan menggunakan metode ORID (Objective, Reflective,Interpretative dan Decision) dengan tiga alternatif jawaban yaitu setuju, ragu-ragudan tidak setuju.

Geographically, thethree locations researchwere in coastal areas potentially affected by the tsunamidisaster in the future. The purpose of this research was to analyze the level ofcapacity and vulnerability of women, to analyze the influence of demographicfactors on the capacities and vulnerabilities and analyzied the strategies toincrease capacity and reduce the vulnerability of women in the effort of tsunamidisaster risk reduction in the coastal areas of Peukan Bada District in Aceh Besar.This research used combination methods (mixed methods) by using quantitativeand qualitativedata approach. The sample in this research consisted of 81 womenwho were determined using the survey method with Quota sampling techniques.The primary data obtained through questionnaires to respondents and structuredinterviews with 6 informants who live in the three villages research. Secondarydata were obtained from Keuchik documentation and the data from StatisticCentre Agency (BPS). The questionnaire prepared using ORID methods(Objective, Reflective, Interpretative and Decision) with three alternative answerswere agree, undicided and disagree. The results showed that (1) The level ofwomen capacitywerein the less ready category with the index 54 and the level ofwomen vulnerability were in the low category with the index 53, (2) Theinfluence of demographic factors on the capacity, significantly on the age, whileeducation factor, employment, income and marital status did not havesignificantly influences.
