    Web users are seizing on interactive capabilities that software suppliers have developed so far, and are eagerly awaiting new interactive capabilities now being demonstrated. This paper focuses the development of rich information environment based on a customized platform enabling hyperlinks on objects within a digital video. With the help of such environment, the viewer is able to view multiple videos concurrently and browse them temporally as well as spatially with the help of an object database. Specifically, the platform enables to traverse through that object by linking, and such links have been explored and created. The link may connect to within a video, or multiple running videos and/or World Wide Web object. The issues such as open hypermedia link base (static, generic or dynamic) and object database versus multiple videos are also investigated

    Are Two Interviews Better Than One? Memory across Repeated Cognitive Interviews.

    No full text
    Eyewitnesses to a filmed event were interviewed twice using a Cognitive Interview to examine the effects of variations in delay between the repeated interviews (immediately & 2 days; immediately & 7 days; 7 & 9 days) and the identity of the interviewers (same or different across the two repeated interviews). Hypermnesia (an increase in total amount of information recalled in the repeated interview) occurred without any decrease in the overall accuracy. Reminiscence (the recall of new information in the repeated interview) was also found in all conditions but was least apparent in the longest delay condition, and came with little cost to the overall accuracy of information gathered. The number of errors, increased across the interviews, but the relative accuracy of participants' responses was unaffected. However, when accuracy was calculated based on all unique details provided across both interviews and compared to the accuracy of recall in just the first interview it was found to be slightly lower. The identity of the interviewer (whether the same or different across interviews) had no effects on the number of correct details. There was an increase in recall of new details with little cost to the overall accuracy of information gathered. Importantly, these results suggest that witnesses are unlikely to report everything they remember during a single Cognitive Interview, however exhaustive, and a second opportunity to recall information about the events in question may provide investigators with additional information

    The Role of Muhammad Umar Memon in Fictional Translations

    The history of fiction translation in Urdu Language is not veryold and one of the able translator we see in this history isMUHAMMAD UMAR MEMON. The element of creativity canbe seen prominently in its translations. He adapted the works ofArabic, French, English, Czech writers into Urdu style such away that due to the rare use of similes, the meaning was freedfrom the confines of the text even for the Urdu Readers. Themain merit of MemonLs translations is that while having acreative element, do not depart form the source text so that thestory reach the target in that style the author intended. Thepleasant style in which the complicated plot story is welladopted to the target language is a proof of its trustworthiness

    Far infrared studies of diatomic cubic crystals by dispersive Fourier transform spectroscopy

    The far infrared optical properties and complex dielectric response functions of two alkali halide crystals (CsT and KI) and two III-V compound semiconductor crystals (InAs and InP) have been studied using the technique of dispersive Fourier transform spectroscopy. The values of the transverse optic and longitudinal optic phonon frequencies at wave vector q=0 determined from these results agree quite well with published values, and the dielectric functions were used to calculate the imaginary parts of the an harmonic self-energies (oj,V) of the q=0 transverse optic modes. These are the first reported measurements on Csl by dispersive Fourier transform spectroscopy, and reasonable agreement is obtained between the frequencies of measured features in (oj,V ) and published two-phonon frequencies. In the case of KI the present measurements have been made at a higher resolution than any reported previously, and they provide a sensitive test of the validity of various theoretical calculations available in publications. Also, in the case of KI some two-phonon difference bands have been observed and assigned in the, spectrum of (oj,V) for the first time. No measurements of the optical constants of InP in the far infrared region using this technique have been reported before, and, for both In Lambdas and InP, these are the first reported experimental determinations of the imaginary part of the frequency dependent damping function. A number of features in the spectra of (oj 'V ) for In Lambdas and InP are revealed and attributed to two-phonon decay processes with the aid of a critical point analysis based on published data for these materials. Since the performance of the dispersive reflection interferometer was limited by the specimen size a prototype focused beam interferometer was constructed, and its performance has been demonstrated by recording a water vapour absorption spectrum at a resolution of 2 cm using end mirrors 5mm in diameter.<p

    False claims about false memory research

    Pezdek and Lam [Pezdek, K. & Lam, S. (2007). What research paradigms have cognitive psychologists used to study “False memory,” and what are the implications of these choices? Consciousness and Cognition] claim that the majority of research into false memories has been misguided. Specifically, they charge that false memory scientists have been (1) misusing the term “false memory,” (2) relying on the wrong methodologies to study false memories, and (3) misapplying false memory research to real world situations. We review each of these claims and highlight the problems with them. We conclude that several types of false memory research have advanced our knowledge of autobiographical and recovered memories, and that future research will continue to make significant contributions to how we understand memory and memory errors

    The Effect of Priming Biblical Benevolence on Prosocial Behavior Rabia Memon

    abstract: Religion and the belief in supernatural agents have been assumed to play an important role in encouraging prosocial behavior. However, different studies conducted have shown a complex relation between religion and prosociality. For example, Darley & Batson (1973) found that religious people do not always help strangers. In the present study, Christian participants were primed with benevolent commandments attributed to either the Bible or past historical figures or secular, non-benevolent quotes (control). I then measured their willingness to help pick up envelopes dropped by either a Muslim (wearing a hijab) or non-Muslim confederate woman. The results show that subjects primed with Bible or presidential quotes about benevolence were more likely to be helpful to the Muslim confederate than those in the control group. Differences between the Bible and presidential condition were not significant. I conclude that an authority, whether it be a president or God, promoting benevolence can increase prosocial behaviors toward out-group members
