Online Social Communities Through the Lens of Polyvore

Traditionally, people used the Internet for simple interaction within the communication sphere.With the introduction of social media platforms the online world has become more interesting as consumers are using them to create, share, and discuss over the Internet. The growing popularity of the social online communities is bridging the gap between consumers and brands by providing them with a platform to communicate with each other. This study visually analyzes Polyvore, a social shopping online community. It sheds light upon how members use Polyvore in different ways, the hedonic motivations associated with shopping online, and the way in which an online community with a growing aspect of offline meetups is used by its members to make social connections

Specific and Diffuse Cultural Orientation How it Impacts Evaluations of Brand Extensions with Varying Category Distance

This paper examines how cultural differences, in particular the specific versus diffuse oriented dimension, can influence brand extension evaluations. Although brand extensions themselves have been studied time and time again over the last few decades, the relationship between consumers from specific and diffuse cultures, brand extension category distance, and overall brand extension evaluation, has not been examined. Through data collection from corporate company websites across countries spanning the cultural spectrum, and analysis against the specific versus diffuse cultural dimension, this paper established a causal relationship indicating that cultural differences account for variance in how brand extensions are evaluated.http://deepblue.lib.umich.edu/bitstream/2027.42/167739/1/Maansi Dalmia.pd

Bruxism: Prevalence among Software Professionals

Background: Software professionals perform boundary-spanning activities and are always at the fear of job security and cost cut-offs. These characteristics of the software professionals are bound to have massive impact on their healthy living. Many studies have related bruxism with stress. Thus, this study is conducted to know the prevalence of bruxism among software professionals. Aims: To know the prevalence of bruxism among software professionals. Methods: A total of 232 randomly selected software professionals working for NASSCOM registered Bangalore based software companies were considered for the study. A questionnaire was specially developed to know the study subject’s demographic data, self reported bruxism data, details on personal habits and other details. The bruxism was recorded as per the ASDA clinical research diagnostic criteria for bruxism. The data was subjected to statistical analysis.  Results: In the study sample, prevalence of bruxism was 35.5% with no difference between genders. Bruxism rarely occurs alone. Conclusion: The prevalence of bruxism in the study population is 35.5%.The results of this study raise an important concern about the prevalence of bruxism among software professionals

Coronary artery aneurysm in Kawasaki disease.

A 3-year-old male presents to the emergency department with chief complaints of fever and vomiting. He had a positive rapid streptococcus throat test with cervical lymphadenopathy. The patient was started on antibiotics. On examination, there was diffuse erythematous macular rash on the chest. Laboratory tests revealed elevated white cell count and C-reactive protein. Electrocardiogram was notable for prolonged PR interval indicating 1st degree atrioventricular block. Echocardiogram revealed ectasia of the right coronary artery (RCA). A presumptive diagnosis of Kawasaki disease was made and the patient was started on high-dose aspirin and intravenous immunoglobulins. Cardiac computed tomography angiography (CTA) showed an aneurysm of the proximal RCA measuring up to 7.4 mm. The RCA immediately proximal to the aneurysm measured 3 mm in diameter. The Z score was 13.4. Oblique coronal image from cardiac CTA and volume rendered images demonstrated an aneurysm of the proximal RCA. The patient improved with treatment

Attention and Recall of Point-of-sale Tobacco Marketing: A Mobile Eye-Tracking Pilot Study

Introduction: As tobacco advertising restrictions have increased, the retail ‘power wall’ behind the counter is increasingly invaluable for marketing tobacco products. Objective: The primary objectives of this pilot study were 3-fold: (1) evaluate the attention paid/fixations on the area behind the cash register where tobacco advertising is concentrated and tobacco products are displayed in a real-world setting, (2) evaluate the duration (dwell-time) of these fixations, and (3) evaluate the recall of advertising displayed on the tobacco power wall. Methods: Data from 13 Smokers (S) and 12 Susceptible or non-daily Smokers (SS) aged 180–30 from a mobile eye-tracking study. Mobile-eye tracking technology records the orientation (fixation) and duration (dwell-time) of visual attention. Participants were randomized to one of three purchase tasks at a convenience store: Candy bar Only (CO; N = 10), Candy bar + Specified cigarette Brand (CSB; N = 6), and Candy bar + cigarette Brand of their Choice (CBC; N = 9). A post-session survey evaluated recall of tobacco marketing. Key outcomes were fixations and dwell-time on the cigarette displays at the point-of-sale. Results: Participants spent a median time of 44 seconds during the standardized time evaluated and nearly three-quarters (72%) fixated on the power wall during their purchase, regardless of smoking status (S: 77%, SS: 67%) or purchase task (CO: 44%, CSB: 71%, CBC: 100%). In the post session survey, nearly all participants (96%) indicated they noticed a cigarette brand and 64% were able to describe a specific part of the tobacco wall or recall a promotional offer. Conclusions: Consumers are exposed to point-of-sale tobacco marketing, regardless of smoking status. FDA should consider regulations that limit exposure to point-of-sale tobacco marketing among consumers

Dataset size considerations for robust acoustic and phonetic speech encoding models in EEG

In many experiments that investigate auditory and speech processing in the brain using electroencephalography (EEG), the experimental paradigm is often lengthy and tedious. Typically, the experimenter errs on the side of including more data, more trials, and therefore conducting a longer task to ensure that the data are robust and effects are measurable. Recent studies used naturalistic stimuli to investigate the brain's response to individual or a combination of multiple speech features using system identification techniques, such as multivariate temporal receptive field (mTRF) analyses. The neural data collected from such experiments must be divided into a training set and a test set to fit and validate the mTRF weights. While a good strategy is clearly to collect as much data as is feasible, it is unclear how much data are needed to achieve stable results. Furthermore, it is unclear whether the specific stimulus used for mTRF fitting and the choice of feature representation affects how much data would be required for robust and generalizable results. Here, we used previously collected EEG data from our lab using sentence stimuli and movie stimuli as well as EEG data from an open-source dataset using audiobook stimuli to better understand how much data needs to be collected for naturalistic speech experiments measuring acoustic and phonetic tuning. We found that the EEG receptive field structure tested here stabilizes after collecting a training dataset of approximately 200 s of TIMIT sentences, around 600 s of movie trailers training set data, and approximately 460 s of audiobook training set data. Thus, we provide suggestions on the minimum amount of data that would be necessary for fitting mTRFs from naturalistic listening data. Our findings are motivated by highly practical concerns when working with children, patient populations, or others who may not tolerate long study sessions. These findings will aid future researchers who wish to study naturalistic speech processing in healthy and clinical populations while minimizing participant fatigue and retaining signal quality

Gunshot-Related Pediatric Left Ventricular Apical Aneurysm

Penetrating injuries of the thorax and abdomen, such as gunshot and stabbing, are rare in children. We present the case of a pediatric patient with a history of remote gunshot injury presenting with a late aneurysm in the left ventricle
