Gender Differences in Student Attitude toward Privacy in Facebook

Facebook is the leading social media. However, a user’s failure to configure Facebook’s privacy settings properly may lead to unwanted or harmful information disclosure. In effect, a user could be sharing private information, such as name, address, contact information, gender, birthdate, views and affiliations with everyone. In this study, we present the results of an examination of students’ use of privacy settings in Facebook as well as their attitudes toward the risks associated with usage of both Facebook and the Internet in general. We also look for the existence of gender differences. Potential weaknesses of this study and suggestions for future research are also discussed

Micro-Loans In Ghana: Assessing Relationships Between Payment Of Interest And Loan Characteristics

This paper assesses differences in loan characteristic variables between those who pay interest on their micro-loans and those who don’t. The findings indicate significant differences between interest payers and interest non payers based on the sufficiency of the loans, the recency of the business and loan, and the portion of profits needed to repay loans

Facebook Privacy Attitudes: A Comparison of Two Minority Groups

Because of Facebook’s ubiquitous nature, users who fail to properly configure their Facebook account privacy settings could be unintentionally revealing personal information to millions of people. This study analyzes data collected from African American and Hispanic college students regarding Facebook privacy setting attitudes and use. The findings indicate African American students have been members of Facebook longer and have more “Friends” than Hispanic students. Both ethnic groups spend about the same amount of time on Facebook during each session, although Hispanics log on more frequently. Virtually all the students claim awareness and use Facebook privacy settings. Hispanics have more restrictive Facebook privacy settings than African Americans. Neither ethnic group trusts Facebook to protect privacy, but African Africans show less concern while Hispanics indicate greater worry about Facebook privacy and data security. Both ethnic groups are more concerned about Internet privacy than Facebook privacy, Hispanics significantly more so

An Examination of the Impact of Gender and Culture on Facebook Privacy and Trust in Guam

Facebook, the world’s largest social network, allows users to develop a profile containing personal information. Users may choose privacy settings to control information access, but improper settings risk personal exposure. Several US studies examining gender differences in privacy management found that females have more privacy concerns. This study investigates gender differences in Facebook privacy settings among college students in Guam, a US territory whose ethnicity and culture differ from mainland US. Results show that neither gender trusts Facebook nor feels Facebook protects them. Significant differences in number and type of privacy settings indicate females are more security conscious. Gender differences exist in three of Hofstede’s five cultural factors, but only Masculinity-Femininity significantly influences perceptions of Facebook Privacy and Facebook Trust. There is also evidence of “privacy paradox” phenomenon. Summarizing for the case in Guam, the findings indicate that culture, in particular Masculinity-Femininity, influences the formation of perceptions regarding both trust in social media and the privacy protection provided by social media, while gender can influence the protective measures actually taken by individuals

Wikipedia as informal self-education for clinical decision-making in medical practice

Background For almost any topic, a Wikipedia page will appear among the first ten items of a search online. Wikipedia is also a site whose quality and reliability has been called into question. Methods In this paper, we aim to discuss medical practitioners’ use of Wikipedia, what this consists of and what it might be. We consider the context and history of Wikipedia before discussing the relationship between Wikipedia and the medical profession. In so doing, we will consider Wikipedia as a means of informal self-education and the extent to which it might inform clinical decision-making. We compare with the existing literature results from our two small-scale empirical studies of Wikipedia and clinical decision-making. Results Notwithstanding issues over quality and reliability, Wikipedia’s rules on verifiability are such that its articles are very heavily referenced, and this is just as true of health-related articles. The Cochrane/Wikipedia Initiative in improving the quality and reliability of medical and health pages in Wikipedia is significant in increasing reliability. Our respondents largely concurred with the results from earlier studies on the use of Wikipedia by medical practitioners. Conclusion Perhaps the very doubt over Wikipedia’s accuracy is its greatest strength as a means of informal education of doctors. That medical and health articles on Wikipedia can be so fully referenced and still be doubted is arguably a good thing and one whose effects may be spread into other, more trusted, publications. Hence, one might envisage a future where no one source is taken automatically on trust. Keywords Wikipedia, informal education, continued professional development, medical education

The Neurocognition of Prosody

Prosody is one of the most undervalued components of language, despite its fulfillment of manifold purposes. It can, for instance, help assign the correct meaning to compounds such as “white house” (linguistic function), or help a listener understand how a speaker feels (emotional function). However, brain-based models that take into account the role prosody plays in dynamic speech comprehension are still rare. This is probably due to the fact that it has proven difficult to fully denote the neurocognitive architecture underlying prosody. This review discusses clinical and neuroscientific evidence regarding both linguistic and emotional prosody. It will become obvious that prosody processing is a multistage operation and that its temporally and functionally distinct processing steps are anchored in a functionally differentiated brain network

Tropospheric O 3 moderates responses of temperate hardwood forests to elevated CO 2 : a synthesis of molecular to ecosystem results from the Aspen FACE project

1.   The impacts of elevated atmospheric CO 2 and/or O 3 have been examined over 4 years using an open-air exposure system in an aggrading northern temperate forest containing two different functional groups (the indeterminate, pioneer, O 3 -sensitive species Trembling Aspen, Populus tremuloides and Paper Birch, Betula papyrifera , and the determinate, late successional, O 3 -tolerant species Sugar Maple, Acer saccharum ). 2.   The responses to these interacting greenhouse gases have been remarkably consistent in pure Aspen stands and in mixed Aspen/Birch and Aspen/Maple stands, from leaf to ecosystem level, for O 3 -tolerant as well as O 3 -sensitive genotypes and across various trophic levels. These two gases act in opposing ways, and even at low concentrations (1·5 × ambient, with ambient averaging 34–36 nL L −1 during the summer daylight hours), O 3 offsets or moderates the responses induced by elevated CO 2 . 3.   After 3 years of exposure to 560 µmol mol −1 CO 2 , the above-ground volume of Aspen stands was 40% above those grown at ambient CO 2 , and there was no indication of a diminishing growth trend. In contrast, O 3 at 1·5 × ambient completely offset the growth enhancement by CO 2 , both for O 3 -sensitive and O 3 -tolerant clones. Implications of this finding for carbon sequestration, plantations to reduce excess CO 2 , and global models of forest productivity and climate change are presented.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72125/1/j.1365-2435.2003.00733.x.pd

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino
