Social Networks and Trade Liberalization

We discuss how social considerations can affect the desirability of trade liberalization in a conventional small open economy model. We consider a representative family in which there are location specific network effects from interactions with other family members, such as joint consumption, joint emotional support, and coinsurance. The benefits an individual receives from the network they participate in are nonlinearly related to the number of family members located in urban and rural areas. Family members choose whether to locate in urban or rural areas and average and marginal network benefits differ. With differential network effects in urban and rural areas, in a model with traded urban and rural goods, free trade will no longer be the best policy. We show this through a numerical example, and suggest that the conventional economists case for free trade may need to be more nuanced once social considerations of this type are taken into account.

Spatial, Temporal and Text Mining - Security, Privacy and Ethical Issues

The World Wide Web (or www) has impacted on almost each aspect of our lives. It is the main widely known information source that is easily available and searchable. It consists of billions of interconnected Web pages) which are uploaded and written by millions of people. Web has dramatically changed our information seeking behavior and lifestyle. With the World Wide Web information is only a few clicks away from us. We can find needed information on the Web and also we can easily share information and knowledge with others. The WWW is officially an Internet-based computer network which allows user to access information stored on another computer through the world-wide network called the Internet. This world-wide network follows a standard client-server model. In this model, a client relies on a program on one end and connects to a remote machine called the server where the data is stored. Web browsers like Netscape, Internet Explorer, Firefox work by sending requests to remote servers for information retrieval and interpret the returned documents in HTML in the form of text and graphics on the computer screen on the client side. Hypertext link on a Web Page allows author to link their documents to other related documents residing on computers anyplace in the world. To view these documents, one simply follows the hyperlinks

Impact of Trade on Productivity of Skilled and Unskilled Intensive Industries: A Cross-Country Investigation

This paper examines the effect of trade openness on the productivity of skilled labor intensive and unskilled labor intensive industries in the group of 20 OECD countries. Using panel data and fixed effects approach, we find that skilled workers’ relative gains in productivity exceed those of their unskilled counterpart. Given this differential impact of trade openness on the relative productivity of the skilled and unskilled intensive industries, our findings lend support to the conclusions of past studies that skilled labor is likely to be more pro trade than unskilled labor.Trade openness; Skilled intensive industries; Unskilled intensive industries; Productivity

RELATIONSHIP OF CORE STRENGTH AND ISOKINETIC KNEE STRENGTH WITH VERTICAL JUMP PERFORMANCE IN VOLLEYBALL

Background: The game of Volleyball requires the players to perform dynamic movements in receiving the ball and performing explosive movements in spiking and blocking. Vertical jump (VJ) becomes one of the basic motor ability in volleyball owing to its frequent involvement during spiking, blocking, and setting the ball for attack. Although considerable work has been done, the relationship between core strength (Trunk Flexion (TF) & Back Extension (BE)) and vertical jump remains unclear. Thus, the present study was aimed at finding relationship between core strength-endurance and vertical jump performance. Method: 20 male players (Age=18.05±0.76 years; Height=192.75±5.88cm; Weight=77.67±7.37kg) from Indian National U-20 Volleyball team were tested on an Isokinetic Dynamometer at 600*s-1, 900*s-1 and 1200*s-1 angular speeds for strength testing, on DAVID systems for trunk flexion and back extension and on sergeant test for vertical jump. Results: Core strength-endurance (TF & BE) and isokinetic concentric Quadriceps strength at 1200*s-1 (CDQ120) for dominant leg were significantly positively correlated to vertical jump (TF vs VJ: r=0.507, p=0.023; BE vs VJ: r=0.453, p=0.045; CDQ120 vs VJ: r=0.595, p=0.006) while isokinetic strength for non-dominant leg approximated significance with increasing velocities. Also, core strength (TF & BE) was significantly positively related with FlightTime (FT) (TF vs FT: r=0.497, p=0.026; BE vs FT: r=0.568, p=0.009). Conclusion: The significant positive correlation of core strength with vertical jump and FlightTime establishes core strength as an integral component of sports training in Volleyball. Although, eccentric quadriceps strength and hamstring strength were not positively correlated to vertical jump, they help in safe landing mechanism and reduce injury-risks. The small sample size of the study warrants further investigations with larger sample size to confirm the findings.  Article visualizations

First moment of Hecke eigenvalues at the integers represented by binary quadratic forms

In the article, we consider a question concerning the estimation of summatory function of the Fourier coefficients of Hecke eigenforms indexed by a sparse set of integers. In particular, we provide an estimate for the following sum; \begin{equation*} \begin{split} S(f, \mathcal{Q}; X ) &:= \sideset{}{^{\flat }}\sum_{n= \mathcal{Q}(\underline{x}) \le X \atop \gcd(n,N) =1 } \lambda_{f}(n), \end{split}\end{equation*} where $\flat$ means that sum runs over the square-free positive integers, $\lambda_{f}(n)$ denotes the normalised $n^{\rm th}$ Fourier coefficients of a Hecke eigenform $f$ of integral weight $k$ for the congruence subgroup $\Gamma_{0}(N)$ and $\mathcal{Q}$ is a primitive integral positive-definite binary quadratic forms of fixed discriminant $D<0$ with the class number $h(D)=1$. As a consequence, we determine the size, in terms of conductor of associated $L$-function, for the first sign change of Hecke eigenvalues indexed by the integers which are represented by $\mathcal{Q}$. This work is an improvement and generalisation of the previous results.Comment: 16 page

Screening and prevalence of vitamin B12 deficiency among pregnant women

Background: Vitamin B12 deficiency (serum vitamin B12 <148pmol/L) is considered to be an important cause of anaemia in pregnancy. Pregnant women with this deficiency have an increased risk of developing preeclampsia, intra-uterine growth retardation and preterm labour. The current study was undertaken to determine the prevalence of vitamin B12 deficiency in pregnant women and its association with their dietary habits and socioeconomic status.Methods: This was a cross sectional study conducted in a tertiary care institute over a period of 2 months. Pregnant women visiting antenatal OPD were included in the study and those receiving vitamin B12 supplements, antacids, antiepileptic medication or methotrexate were excluded. Each participant was subjected to a predesigned structured questionnaire and their serum vitamin B12 concentration was done using quantitative determination by microplate enzyme immunoassay.Results: Of the 97 women included, majority were in the age group 20-25years (57.73%). 87.62% (85 women) were found to have anaemia and a total of 44women (45.36%) had vitamin B12 deficiency.Conclusions: The prevalence of vitamin B12 deficiency in north India is considerably high, which may be the cause of neural tube defects and poor birth outcomes and neurological deficit in children born to these mothers

Novel: A Genre in the Hands of Capitalist Class

The ‘Novel’ as a literary phenomenon is new to India. In comparison to, Epics, lyrics, drama, short stories and fables that have its ancestries which go back to several centuries. In the west, the literary tool 'Novel' was the offshoot of industrialization whereas in India, it was due to the Indian scholars educated in English who introduced it to the literary world. Both the part of the world used it to cater the needs of newly structured society. Industrialization drew rural population in search of jobs towards the cities. This led to the change in the social realities and life styles of the people, eventually resulting into unpredictable consequences and struggle for them. In spite of it, the Capitalist system was able to hold them back. The previous genres were not reflecting the current realities in which people were living. All the new realities created, had a unique demand that led to the formation of Genre ‘Novel’
