Evaluating information seeking and use in the changing virtual world: the emerging role of Google Analytics     

D.J. CLARK  David NICHOLAS  Hamid R. JAMALI 《Learned Publishing》2014,27(3):185-194

The paper identifies changes that have occurred in the Web environment over the last decade which have gradually rendered server logs, once the preeminent source of intelligence on usage and information‐seeking behaviour, an ineffective, impractical, and uneconomic resource. It also looks at the implications of these changes for information professionals and publishers who have come to rely on this data to understand the behaviour of clients and customers in the virtual environment. Ubiquitous and expanding, Google Analytics generates statistics about a website's traffic and traffic sources, albeit from a marketers' perspective, is evaluated as a possible replacement; something which might plug the user knowledge gap which is worryingly opening up, or maybe even, put us in a better position overall. The paper is built on the knowledge and experience of evaluating server logs for more than a decade, mostly for publishers and libraries, and also on two recent projects where server log analysis was supplemented with Google Analytics.  相似文献   

The impact of the pandemic on early career researchers' work-life and scholarly communications: A quantitative aerial analysis

After two-years of repeat interviewing early career sciences/social sciences researchers from around the world about their work life and scholarly communications in pandemic-times, the Harbingers-2 project is in a position to release quantitative data on the pandemic's overall impact. The data comes from around 50 questions asked in the third and final round of interviews with 147 early career researchers (ECRs), which had a codifiable element to them (such as yes, no, do not know). The 19 scholarly topics covered include: pandemic-related research; research funding; changes to the workplace/working from home; pandemic-incurred stress and anxiety; teaching; employment security; career progression; mentoring; assessment (including metrics); collaboration; searching/finding information; ethics; networking; informal communication; publishing; sharing; pre-prints; outreach; and scholarly transformations. The main findings are that in six broad aspects of ECRs' work-life and scholarly behaviour, more than 50% of ECRs were impacted by the pandemic, with remote teaching having the greatest impact. By way of comparison, in another six aspects there was little change, least of all when it came to sharing activities. Among the countries studied, Malaysia stood out as being the most impacted, and of the disciplines it was the medical sciences and the soft social sciences most impacted.  相似文献

Nephroprotective effects of Zingiber zerumbet Smith ethyl acetate extract against paracetamol-induced nephrotoxicity and oxidative stress in rats     

Zariyantey Abdul Hamid  Siti Balkis Budin  Ng Wen Jie  Asmah Hamid  Khairana Husain  Jamaludin Mohamed 《Journal of Zhejiang University. Science. B》2012,13(3):176-185

Paracetamol (PCM) overdose can cause nephrotoxicity with oxidative stress as one of the possible mechanisms mediating the event. In this study, the effects of ethyl acetate extract of Zingiber zerumbet rhizome [200 mg per kg of body weight (mg/kg) and 400 mg/kg] on PCM-induced nephrotoxicity were examined. Rats were divided into five groups containing 10 rats each. The control group received distilled water while other groups were treated with extract alone (400 mg/kg), PCM alone (750 mg/kg), 750 mg/kg PCM+200 mg/kg extract (PCM+ 200-extract), and 750 mg/kg PCM+400 mg/kg extract (PCM+400-extract), respectively, for seven consecutive days. The Z. zerumbet extract was given intraperitoneally concurrent with oral administration of PCM. Treatment with Z. zerumbet extract at doses of 200 and 400 mg/kg prevented the PCM-induced nephrotoxicity and oxidative impairments of the kidney, as evidenced by a significantly reduced (P<0.05) level of plasma creatinine, plasma and renal malondialdehyde (MDA), plasma protein carbonyl, and renal advanced oxidation protein product (AOPP). Furthermore, both doses were also able to induce a significant increment (P<0.05) of plasma and renal levels of glutathione (GSH) and plasma superoxide dismutase (SOD) activity. The nephroprotective effects of Z. zerumbet extract were confirmed by a reduced intensity of renal cellular damage, as evidenced by histological findings. Moreover, Z. zerumbet extract administered at 400 mg/kg was found to show greater protective effects than that at 200 mg/kg. In conclusion, ethyl acetate extract of Z. zerumbet rhizome has a protective role against PCM-induced nephrotoxicity and the process is probably mediated through its antioxidant properties.  相似文献   

Utilization of discrete transforms to conquer the problems of multi-tone systems     

Samir Abd Elghafar  Salaheldin M. Diab  Bassiouny M. Sallam  Emad S. Hassan  Mona Shokair  Waleed Al-Nauimy  Moawad I. Dessouky  El-Sayed M. El-Rabaie  Saleh Alshebeili  Fathi E. Abd El-Samie 《Journal of The Franklin Institute》2014

This paper presents a new implementation of discrete multi-tone (DMT) systems based on different discrete transforms that include the discrete sine transform (DST), discrete cosine transform (DCT), and discrete wavelet transform (DWT). The implementation also considers time-domain equalization to mitigate channel distortion. Compared to the fast Fourier transform discrete multi-tone (FFT-DMT) system, the proposed implementations have an advantage in that their energy-compaction property helps in reducing the channel effects. The performance of the DST-DMT, DCT-DMT, DWT-DMT, and FFT-DMT systems, employing a time-domain equalizer (TEQ), is investigated in the paper. It has been demonstrated by computer simulations that the proposed implementations outperform the FFT-DMT system and that the utilization of the TEQ can lead to higher bit rates  相似文献   

Finite-time stability analysis and stabilization for linear discrete-time system with time-varying delay     

Zhuo Zhang  Zexu Zhang  Hui Zhang  Bo Zheng  Hamid Reza Karimi 《Journal of The Franklin Institute》2014

The problem of finite-time stability for linear discrete-time systems with time-varying delay is studied in this paper. In order to deal with the time delay, the original system is firstly transformed into two interconnected subsystems. By constructing a delay-dependent Lyapunov–Krasovskii functional and using a two-term approximation of the time-varying delay, sufficient conditions of finite-time stability are derived and expressed in terms of linear matrix inequalities (LMIs). The derived stability conditions can be applied into analyzing the finite-time stability and deriving the maximally tolerable delay. Compared with the existing results on finite-time stability, the derived stability conditions are less conservative. In addition, for the stabilization problem, we design the state-feedback controller. Finally, numerical examples are used to illustrate the effectiveness of the proposed method.  相似文献   

The determinants of individuals’ perceived e-security: Evidence from Malaysia     

Mahmood Hussain Shah  Hamid Reza Peikari  Norjaya M. Yasin 《International Journal of Information Management》2014

Despite the critical role of individuals’ perceived security in an online environment, previous research has not attempted to comprehensively study the influences and interrelations between the determinants of online individuals’ perceived security. This research employs five theories to examine the interrelations that might exist between the antecedents of individuals’ perceived security in online environment in Malaysia. It is the first attempt to empirically examine the interrelations of the confidentiality related factors identified in the literature which is a significant original contribution. A questionnaire was the primary research methodology and structural equation modeling was employed to test the hypotheses. The findings suggest that individuals’ perceptions about security are significantly influenced by their perceived technical protection while technical protection was found to be influenced by website design features. Moreover, it was found that individuals’ perceptions toward internally provided assurances are highly influenced by externally provided assurances. However, the results found no significant relations between internally and externally provided assurances about a website's security. The findings imply that e-retailers should launch well-designed websites and communicate the technical protection capabilities of their websites to address individuals’ security concerns. The results also suggest that e-traders should consider the factors influencing individuals’ security perceptions when designing/developing their websites.  相似文献   

Influences on the survival of new consumer magazines     

Samir A. Husni 《Journal of Media Economics》2013,26(1):39-49

This study tracks magazines started from 1981 to 1983 that have survived to the present. It finds that magazines started by entrepreneurs, rather than media firms, and magazines that were consumer driven, rather than advertising driven, were more likely to survive.  相似文献   

Intergenerational effects of war trauma among Palestinian families mediated via psychological maltreatment     

Esa Palosaari  Raija-Leena Punamäki  Samir Qouta  Marwan Diab 《Child abuse & neglect》2013

We tested the hypothesis that intergenerational effects of parents’ war trauma on offspring's attachment and mental health are mediated by psychological maltreatment. Two hundred and forty children and their parents were sampled from a war-prone area, Gaza, Palestine. The parents reported the number and type of traumatic experiences of war they had had during their lifetime before the child's birth and during a current war when the child was 10–12 years old. The children reported their war traumas, experiences of psychological maltreatment, attachment security, and symptoms of posttraumatic stress (PTSS), depression, and aggression. The direct and indirect intergenerational effects of war trauma were tested in structural equation models. The hypotheses were confirmed for father's past war exposure, and disconfirmed for mother's war exposure. The father's past war trauma had a negative association with attachment security and positive association with the child's mental health problems mediated by increased psychological maltreatment. In contrast, the mother's past war trauma had a negative association with the child's depression via decreased psychological maltreatment. The mother's current war trauma had a negative association with the child's depression and aggression via decreased psychological maltreatment. Among fathers, past war exposure should be considered as a risk factor for psychological maltreatment of children and the associated attachment insecurity and mental health problems. Among mothers, war exposure as such could be given less clinical attention than PTSS in the prevention of psychological maltreatment of children.  相似文献
