This paper discusses implicit social consequences of four basic internet protocols. The results are then related to the field of computer-assisted teaching. An educational on-line community is described and compared to the emerging standard of web-based learning management.\u
Automatically Discovering, Reporting and Reproducing Android Application Crashes
Mobile developers face unique challenges when detecting and reporting crashes
in apps due to their prevailing GUI event-driven nature and additional sources
of inputs (e.g., sensor readings). To support developers in these tasks, we
introduce a novel, automated approach called CRASHSCOPE. This tool explores a
given Android app using systematic input generation, according to several
strategies informed by static and dynamic analyses, with the intrinsic goal of
triggering crashes. When a crash is detected, CRASHSCOPE generates an augmented
crash report containing screenshots, detailed crash reproduction steps, the
captured exception stack trace, and a fully replayable script that
automatically reproduces the crash on a target device(s). We evaluated
CRASHSCOPE's effectiveness in discovering crashes as compared to five
state-of-the-art Android input generation tools on 61 applications. The results
demonstrate that CRASHSCOPE performs about as well as current tools for
detecting crashes and provides more detailed fault information. Additionally,
in a study analyzing eight real-world Android app crashes, we found that
CRASHSCOPE's reports are easily readable and allow for reliable reproduction of
crashes by presenting more explicit information than human written reports.Comment: 12 pages, in Proceedings of 9th IEEE International Conference on

A method for securing online community service: A study of selected Western Australian councils
Since the Internet was made publicly accessible, it has become increasingly popular and its deployment has been broad and global thereby facilitating a range of available online services such as Electronic Mail (email), news or bulletins, Internet Relay Chat (IRC) and World Wide Web (WWW). Progressively, other online services such as telephony, video conference, video on demand, Interactive Television (ITV) and Geographic Information System (GIS) have been integrated with the Internet and become publicly available. Presently, Internet broadband communication services incorporating both wired and wireless network technologies has seen the emergence of the concept of a digital community which has been growing and expanding rapidly around the world. Internet and the ever expanding online services to the wider digital community has raised the issue of security of these services during usage. Most local councils throughout Western Australia have resorted to delivering online services such as library, online payments and email accessibility. The provision and usage of these services have inherent security risks. Consequently, this study investigated the concept of a secure digital community in the secure provision and usage of these online services in selected local councils in Western Australia (WA). After an extensive review of existing literature, information security frameworks were derived from the adaptation of various resources, such as the OSSTMM 2.2 Section C: Internet Technology Security benchmark which was used as the main template. In addition, this template was enhanced into a framework model by incorporating other benchmarks such as NIST, CIS, ISSAF as well as other sources of information. These included information security related books, related ICT network and security websites such as CERT, CheckPoint, Cisco, GFI, Juniper, MS, NESSUS and NMAP together with journals and personal interviews. The proposed information security frameworks were developed to enhance the level of security strength of the email and online web systems as well as to increase the level of confidence in the system security within the selected local councils in WA. All the investigative studies were based upon the available selected local councils’ data and the associated analyses of the results as obtained from the testing software. In addition, the interpretive multiple-case study principles were used during the investigation to achieve or fulfil the purpose of this study. The findings from this study were then abstracted for use in a framework and made available for use as a model for possible adaptation and implementation to other similarly structured councils or organisations. As a result, the study confirmed that the proposed information security frameworks have the capability and potential to improve the level of security strength. In addition, the level of satisfaction and confidence of council staff of the selected local councils in WA in the system security would also be increased due to the application of these frameworks. Although these information security frameworks may be recommended as practical and supporting tools for local councils, the findings from this study were specific only to the selected local councils used in this study. Further research using other councils, may be necessary in order for the information security frameworks to be adopted within a wider range of councils or organisations in WA or elsewhere

Building and Delivering the Virtual World: Commercializing Services for Internet Access
This study analyzes the service offerings of Internet Service Providers (ISPs), the commercial suppliers of Internet access in the United States. It presents data on the services of 2089 ISPs in the summer of 1998. By this time, the Internet access industry had undergone its first wave of entry and many ISPs had begun to offer services other than basic access. This paper develops an Internet access industry product code which classifies these services. Significant heterogeneity across ISPs is found in the propensity to offer these services, a pattern with an unconditional urban/rural difference. Most of the explained variance in behavior arises from firm-specific factors, with only weak evidence of location-specific factors for some services. These findings provide a window to the variety of approaches taken to build viable businesses organizations, a vital structural feature of this young market.
