Differences in intention to use educational RSS feeds between Lebanese and British students: A multi‑group analysis based on the technology acceptance model

Really Simple Syndication (RSS) offers a means for university students to receive timely updates from virtual learning environments. However, despite its utility, only 21% of home students surveyed at a university in Lebanon claim to have ever used the technology. To investigate whether national culture could be an influence on intention to use RSS, the survey was extended to British students in the UK. Using the Technology Adoption Model (TAM) as a research framework, 437 students responded to a questionnaire containing four constructs: behavioral intention to use; attitude towards benefit; perceived usefulness; and perceived ease of use. Principle components analysis and structural equation modelling were used to explore the psychometric qualities and utility of TAM in both contexts. The results show that adoption was significantly higher, but also modest, in the British context at 36%. Configural and metric invariance were fully supported, while scalar and factorial invariance were partially supported. Further analysis shows significant differences between perceived usefulness and perceived ease of use across the two contexts studied. Therefore, it is recommended that faculty demonstrate to students how educational RSS feeds can be used effectively to increase awareness and emphasize usefulness in both contexts

A Comparative Study Between Alcoholics of Koraga Community, Alcoholics of General Population and Healthy Controls for Antioxidant Markers and Liver Function Parameters

Objectives: It is well established that long-term alcohol consumption leads to liver cirrhosis and other related disorders. Sufficient work has been done on biochemical markers of liver damage and antioxidant status of chronic alcoholics in general population. In the current study chronic alcoholics from a community called Koraga are analysed for the same parameters in a view to assess the extent of liver damage as compared to healthy controls and other alcoholics. Methods: Serum and urine samples from Koraga alcoholics (n=28), general alcoholics (n=30) and healthy controls (n=31) were analysed for liver function parameters and antioxidant markers. Liver function parameters were determined by automated analyzer. Markers of antioxidant status were estimated spectrophotometrically. The data was analysed using SPSS version 16.0. Results: There was significant increase in serum AST, serum ALT, serum GST and urine GST in both general and Koraga alcoholics when compared to healthy controls (p<0.0001). Serum ALT, serum GST and urine GST activity was significantly higher in general alcoholics when compared to Koraga alcoholics (p<0.001). Serum and urine total thiol levels were significantly lower in general alcoholics when compared to healthy controls and Koraga alcoholics (p<0.0001). We have observed no difference in total thiols level between healthy controls and Koraga alcoholics, in fact, there was significant increase in urine total thiols level in Koraga alcoholics compared to healthy controls (p<0.001). On Pearson’s correlation serum AST, serum ALT correlated positively with serum and urine GST (p<0.0001) and negatively with serum total thiols (p<0.0001). Serum GST correlated negatively with serum total thiols (p<0.0001). Conclusion: Results of our study possibly indicate that the extent of alcohol induced liver damage in Koraga subjects is comparatively lower than general alcoholics, even though the alcohol consumption is found to be higher in them. There may be some mechanism that is rendering them resistant to alcoholic liver damage which needs to be explored through further studies at molecular level

Contributing Factors to Attitudes and Beliefs about Diversity

Diversity is a major issue in the world today. This project studied the attitudes and beliefs about diversity in order to understand where they originate. It focused on family beliefs and educational experiences and whether they each play a role in one’s perspective of other races/ethnicities. The sample consisted of 100 University of New Hampshire undergraduate students recruited through Facebook as well as in-class presentations on campus. Students were asked to complete a survey online. Quantitative results revealed that neither family nor education, as measured with forced-choice questions, were predictive of acceptance of other races. Overall, students reported themselves and their families as being very accepting of other races. However, they noted there was a lack of formal education about the topic of diversity in schools and that they largely came from homogenous schools. Qualitative results reveal that students themselves highlight the importance of exposure to diverse others, family upbringing, the media, and several other key factors as important considerations in how they treat other people; this suggests a multitude of ways that people create their beliefs. Implications for college student curriculum and campus life are highlighted

Task-dependent Modulation of Cortical Excitability and Balance Control in Individuals with Post-concussion Syndrome

In most cases, symptoms resolve between 7-10 days post-concussion. However, in 10-15% of the concussed population, symptoms can remain unresolved for months to years following the head injury. The purpose of this thesis was two-fold, and was broken up into two studies, where the same individuals participated in both studies. The purpose of the first study was to quantify the differences in balance control between individuals with PCS (i.e., had been experiencing symptoms for \u3c30 days) and non-concussed individuals during a lower-limb reaching task. Participants completed a static balance assessment before and after a lower-limb reaching task, which incorporated a Go/No-Go paradigm. Results from this study revealed no differences in the static stability assessments, however, individuals with PCS demonstrated increased medial-lateral COP displacement as well as greater trunk pitch during the reaching task. Overall, the findings reveal persistent balance impairments in individuals with PCS, which may put this population at an increased risk of further injury. The purpose of the second study was to assess task-dependent modulation of cortical excitability prior to planned index finger abduction contractions comparing a non-concussed population to a population with PCS. The protocol in this study consisted of both single and paired-pulse transcranial magnetic stimulation (TMS) which was applied prior to the beginning of 3 different tasks (i.e., a rest condition with no plan to contract, a precision contraction, and a powerful contraction). In addition to the three tasks, participants also had to respond to a Go/No-Go cue. The results of this study revealed an increase in excitability prior to a precision contraction in both non-concussed and PCS groups. No differences in task-dependent modulation were found between the two groups with respect to intracortical facilitation and inhibition, however a negative correlation between number of symptoms reported (SCAT3 symptom evaluation) and intracortical facilitation was revealed. The increase in corticospinal excitability prior to a precision contraction was not explained by the two cortical mechanisms we assessed and may therefore be due to spinal modulation or a different cortical mechanism. Overall, based on the results from this thesis, it appears that individuals with PCS have balance impairments, which may be a result of an inability to maximally activate their postural muscles. Furthermore, it appears that those individuals who reported a higher number of symptoms had greater reductions in intracortical facilitation, likely reflecting the heterogeneity of this clinical group

Unsupervised vector-based classification of single-molecule charge transport data

The stochastic nature of single-molecule charge transport measurements requires collection of large data sets to capture the full complexity of a molecular system. Data analysis is then guided by certain expectations, for example, a plateau feature in the tunnelling current distance trace, and the molecular conductance extracted from suitable histogram analysis. However, differences in molecular conformation or electrode contact geometry, the number of molecules in the junction or dynamic effects may lead to very different molecular signatures. Since their manifestation is a priori unknown, an unsupervised classification algorithm, making no prior assumptions regarding the data is clearly desirable. Here we present such an approach based on multivariate pattern analysis and apply it to simulated and experimental single-molecule charge transport data. We demonstrate how different event shapes are clearly separated using this algorithm and how statistics about different event classes can be extracted, when conventional methods of analysis fail

Impact of GST on E-Commerce

E-commerce as anything that involves an online transaction. E-commerce provides multiple benefits to the consumers in form of availability of goods at lower cost, wider choice and saves time. The general category of e-commerce can be broken down into two parts: E-merchandise: E-finance. E commerce involves conducting business using modern communication instruments: telephone, fax, e-payment, money transfer systems, e-data interchange and the Internet. Online businesses like financial services, travel, entertainment, and groceries are all likely to grow. Forces influencing the distribution of global e-commerce and its forms include economic factors, political factors, cultural factors and supranational institutions. Goods and Service Tax or GST as it is known is all set to be a game changer for the Indian economy. Overall it is known to be beneficial to both the consumer, business and the Government. In India, there are different indirect taxes applied on goods and services by central and state government. GST is intended to include all these taxes into one tax with seamless ITC and charged on both goods and services. Thus excise duty, special additional duty, service tax, VAT to name a few will get repealed and will be added into GST. For this, GST will have 3 parts CGST, SGST and IGST. The central taxes like excise duty will be subsumed into CGST and state taxes like VAT into SGST. This going to be forward on all transactions of both goods and services, only one tax will apply which is GST comprising of CGST and SGST. IGST would be applied instead of SGST for interstate transactions. Input credit of all these taxes will be available against all the respective outputs. This paper is outcome of a review of various research studies carried out on Impact of GST on E-commerce. This paper examines different aspects like No threshold for GST registration, No Benefit under Composition Scheme, Tax Collection at Source by Marketplace Operator. Finally in the conclusion one country and one tax will help Indian Economy to grow Rapidly

Pengaruh Pertumbuhan Ekonomi dan Inflasi terhadap Upah Minimum Provinsi Jambi

Wage is one of the leading indicators to assess needed for decent living from labor who works in a company. The importance of providing wages to labor in accordance with his handiwork as well as the magnitude of the needs is a thing that must be considered by a businessman. This research is based on the phenomenon, whereby the granting of wage is for workers rights/labour in return to work, on the other hand employers saw the wage is cost. The purpose of this research is to find out and analyze the variables of economic growth and inflation against the minimum wage province of Jambi. The Data used in this study is secondary data during the year 2000-2013 sourced from BPS, Disnakertransos, Bappeda of Jambi province. Model analysis used is the regression equation is linear of multiple, being to the testing of hypotheses used test f and test t. The results were obtained regression coefficient of 2,538 variable economic growth. This means that if there is an increase in the economic growth of 1%, the provincial minimum wage will result in an increase of 2,538%. The while variable inflation of – 0,202. This means that if there is an increase in the inflation of 1% will result in the value of the minimum wage declined by 0,202%. The value of f count 6,054 > f table 3,98, and a significant degree 0,017 < alpha 0,05%. It means the independent variable (economic growth and inflation) influential positive and significantly affect the minimum wage Jambi. Based on partial test (t test), variable economic growth and a significant positive effect on the Jambi provincial minimum wage, inflation variable is not significant and is worth a negative coefficient. This fact, indicate inflation can reduce the value of the money received by workers. Because even though the nominal value of the provincial minimum wage will increase but the value of the goods the purchasing power of workers will decrease, consequently the needs of everyday working life are not met
