Social Media Site (SMS) usage has grown rapidly in the last few years. This
sudden increase in SMS usage creates an opportunity for data leakage which
could compromise personal and/or professional life. In this work, we have
reviewed traditional penetration testing process and discussed the failures of
traditional penetration testing process to tes...
In this paper we posit that current investigative techniques—particularly as deployed by law enforcement, are becoming unsuitable for most types of crime investigation. The growth in cybercrime and the complexities of the types of the cybercrime coupled with the limitations in time and resources, both computational and human, in addressing cybercri...
A number of recent incidents, such as the Stanley Cup Riots, the uprisings in the Middle East and the London riots have demonstrated the value of crowd sourced audio-visual evidence wherein citizens submit audio-visual footage captured on mobile phones and other devices to aid governmental institutions, responder agencies and law enforcement author...

The technique exploits the complement value (CV) of each colour image byte to estimate the number of bits to be em...
With increasingly more businesses engaging in offshore outsourcing, organisations need to be made aware of the global differences in network security, before entrusting a nation with sensitive information. In July 2011, Syn and Nackrst1 explored this topic by analysing seven countries from a wide spectrum across the globe for network security vulne...
Recent studies in Sikh musicology have focused on its history and theory. However, there is an absence of theoretical research which focuses on the role of emotions in Sikh music. In this paper, we contribute to this research by investigating key issues relating to emotions in Sikh musicology. We explore theories which propose that a rāga will evok...
Intrusion Detection Systems are an accepted and very useful option to monitor, and detect malicious activities. However, Intrusion Detection Systems have inherent limitations which lead to false positives and false negatives; we propose that combining signature and anomaly based IDSs should be examined. This paper contrasts signature and anomaly-ba...

The introduction of Jumplists in Windows 7 was an important feature from a forensic examiners viewpoint. Jumplist configuration files can provide the examiner with a wealth of information relating to file access and in particular: dates/times, Volume GUIDs and unique file object IDs relating to those files. Some of the information in the Jumplist c...
The numerous advantages offered by cloud computing has fuelled its growth and has made it one of the most significant of current computing trends. The same advantages have created complex issues for those conducting digital forensic investigations. Digital forensic investigators rely on the ACPO (Association of Chief Police Officers) or similar gui...
Identifying academic misdemeanours and actual applied effort in student assessments involving practical work can be problematic. For instance, it can be difficult to assess the actual effort that a student applied, the sequence and method applied, and whether there was any form of collusion or collaboration. In this paper we propose a system of usi...
This paper proposes a hash-based secure interface between two nodes on the Internet, especial between two interfaces or two web pages. Digital signatures and public-private keys are traditionally used to provide integrity and authentication. This paper proposes an alternative method which uses a shared private key and a public hash function for a m...
Internet file sharing via the use of peer-to-peer networks is an activity that has been growing steadily for several years. It has rapidly become the most widespread method for the exchange of digital material and as a result raises much controversy. The current, most popular protocol in this field is BitTorrent. Although it is relatively simple in...

I want to know what the precise formula is that SPSS uses to calculate part worths in a conjoint analysis. Assume that I have three attributes (a, b, c), each attribute has three levels (1, 2, 3). participants will score 9 configurations out of 10. The 9 configurations are generated by SPSS' orthogonal design feature.
SPSS gives me the part worth scores - which is wonderful. However, I want to know exactly how it calculates this. Does anybody have an idea?
I am using SPSS to develop an Orthogonal Design. The design is a 4x3x3x3x3 (324 factors). The following sample syntax automatically generates 16 cards (I don't have to tell it to generate that many).
My question is whether SPSS has 'automatically calculated' the number of cases I should be using for my design, or whether I should influence the number of cards generated. In other words, do I *need to* increase this, or can I rely on the 'judgement' by SPSS to use 16 cases.
Here is my plan:
ORTHOPLAN
/FACTORS=Fruit 'Attribute1' (1 'apple' 2 'Orange' 3 'Pear ' 4 'Raspberry') Chocolate 'Attribute2' (1 'snickers' 2 'wispa' 3 'twix') Pizza 'Attribute3' (1 'Margherita' 2 'plain' 3 'vegetable') drink 'attribute4' (1 'coke' 2 'pepsi' 3 'water') price 'attribute5' (1 'cheap' 2 'not cheap' 3 'expensive')
/OUTFILE='a:\plan.sav'
/MIXHOLD YES.
p.s. I understand that I should add some 'holdout cases' (I will do that in my final study).
How can I add a new plan to a previously created SPSS Conjoint plan? It has 'auto generated' 36, however I need 42. Can I manually add to the SPV file?
Is there any research which has performed a critical/objective comparison of the cognitive impact/effect of visual information charting methods such as flow charts, status charts, Petrinets etc? It appears that we have assumed that 'flow charts are the best way to express 'xyz'....' and that 'Petrinets are good at representing 'abc'...' Has anybody compared methods?
Any comments/pointers very welcome :-)
Ipeirotis published "Demographics of mechanical turk " in 2010.
I think some of the data from there was quoted in Paolacci et al's "Running experiments on amazon mechanical turk. Judgment and Decision making"(2010)
The demographics of MechTurk is important for any researcher. Does anybody know of any more recent research on this topic?
