Social welfare implications of the digital divide

The Internet plays a critical role in informing individuals about society, politics, business, and the environment. So much so that it has been said that the digital divide makes the segment of society on the “right side” of the divide (the digitally endowed group) better off and that on the “wrong side” (the digitally challenged group) worse off. This is not always true, however, in a social choice situation where members of a society collectively choose one alternative from a set of alternatives. To identify conditions when this does not hold, a model of the digital divide is setup in which the digitally endowed group receives better information than the digitally challenged group. Preferences of all individuals over outcomes are distributed over a scale. This distribution is correlated with the digital divide: the outcome preferred by the digitally endowed group differs from that preferred by the other group. The alternative chosen by majority becomes the choice of the overall society. The ensuing analysis shows that individuals located centrally on the preference scale are sensitive to information about the state. The choice of centrally located digitally challenged individuals, made on a lack of information, makes the digitally challenged group worse off as has been predicted before. In some cases, the digitally endowed group is worse off as well. In the case of highly polar alternatives, social welfare decreases due to the welfare loss of the digitally endowed group. Results suggest that policymakers must manage the digital divide in a customized manner depending on the preferences context. They should not only focus on improving the welfare of the digitally challenged, but also focus on the welfare of the digitally endowed group so that this welfare does not decrease.     

Differential contribution of specific working memory components to mathematics achievement in 2nd and 3rd graders

The contribution of the three core components of working memory (WM) to the development of mathematical skills in young children is poorly understood. The relation between specific WM components and Numerical Operations, which emphasize computation and fact retrieval, and Mathematical Reasoning, which emphasizes verbal problem solving abilities in 48 2nd and 50 3rd graders was assessed using standardized WM and mathematical achievement measures. For 2nd graders, the central executive and phonological components predicted Mathematical Reasoning skills; whereas the visuo-spatial component predicted both Mathematical Reasoning and Numerical Operations skills in 3rd graders. This pattern suggests that the central executive and phonological loop facilitate performance during early stages of mathematical learning whereas visuo-spatial representations play an increasingly important role during later stages. We propose that these changes reflect a shift from prefrontal to parietal cortical functions during mathematical skill acquisition. Implications for learning and individual differences are discussed.     

Temporal Trends of Malondialdehyde in Stored Human Plasma

Malondialdehyde (MDA) is widely used as oxidative stress biomarker in biomedical research. Plasma is stored in deep freezers generally till analysis. Effect of such storage on MDA values, which may be variable and prolong, was incidentally observed in the ongoing study which is to estimate oxidative stress with oral iron. Plasma from blood samples of pregnant women (20–30 years age) in third trimester of singleton pregnancy (n = 139), consuming oral iron tablets was stored at −20 °C with intention of MDA estimation, as soon as possible. However logistic problems led this storage for prolonged and variable period (1–708 days). When values of MDA estimated using “Ohkawa” 79 method and readings were plotted against time to check the temporal effect, it showed a hyperbolic curve. Standard deviation (SD) was lowest when samples were tested within 3 weeks time. The samples analyzed within 3 weeks had mean ± SD value of 31.59 ± 26.11 μmol/L, while 123.7 ± 93.97 and 366.5 ± 189.8 μmol/L for samples stored for 1–3 and 4 months to 1 year respectively. Mean ± SD were 539.9 ± 196.8 in the samples store for more than a year. Rate of change in values was also lowest (0.0433 μmol/L/day) in the samples tested within first 3 weeks, which rose to 1.2 μmol/L/day during 3 month’s storage. This rate peaked at storage of 120 days (1.87 μmol/L/day) and fell to 0.502 μmol/L/day in the second year of storage. It is concluded that at −20 °C, only 3 weeks of storage time should be considered valid for fairly acceptable stability in MDA values.     

Subaltern voices and postcolonial schizophrenia: The political tensions of M.I.A.’s Kala

ABSTRACT

Banned from the U.S. during the “war on terror,” the British/Sri Lankan hip-hop artist M.I.A. responded by recording her 2007 album Kala in multiple locations throughout the global South, collating indigenous musical styles and unorthodox recording techniques. Via a critical/cultural analysis, this paper explores M.I.A.’s work on Kala as subaltern resistance mobilized by “differential movement,” particularly in its mode of production, which operated outside of, and in opposition to, institutional mechanisms designed to expunge or neutralize politically subversive art and artists. Yet M.I.A.’s musical sampling also surfaces conflicts between creative freedom and cultural appropriation, emblematizing “postcolonialist/postmodern schizophrenia” (Vályi, 2011.

Kuenzli (Eds.), Cutting across media: Appropriation art, interventionist collage, and copyright law (pp. 219–236). Durham, NC: Duke University Press.).     

Analysis of 175 newborn babies who died in an orphan age

175 newborns who were admitted to an orphanage in the year 1975–1976 and subsequently died are analysed. Illegitimacy was the major cause for abandoning the babies. 46% of the babies were born in hospitals. 5 babies had congenital anomalies and 11 babies had marks of external injury. 58.8% of the babies abandoned were girls, 82.7% of the babies weighed less than 2.5 kgs. and had some degree of intrauterine growth retardation. The major cause of death was infections which accounted for 79.3% of deaths, of which gastroenteritis (43.4%) was the main killer. Septicemia and bronchopneumonia were the two other major infections that contributed to the deaths. Infections were more common in the low weight babies. Gastroenteritis was probably acquired after introduction of top feeds, due to poor hygiene and occured in all age groups. Majority of babies died of septicemia within 7 days of admission suggesting antenatal and natal infections. Chances of survival increased with increasing weight of the baby.     

Forms of Discourse: a typology of teachers and commitment

An attempt is made in this paper to arrive at a typology of teachers within the specific context of two forms of discourse, ideological and educational, which constitute a particular school in India. It is suggested that the mode of recruitment, the teachers’ perspectives on and adaptations to the particular ideology and the role, and their commitment to the same are significant factors contributing to the shaping of a teacher typology. In this particular context, the teacher is thus both defined by and perpetuates the two forms of discourse in the school.

The data on which this paper is based was collected in 1981 through the use of questionnaires, interviews (both structured and unstructured) and observation.

Physical abuse of abandoned children in India

Child abuse and neglect, though existing in India, has not come to light because of underlying social constraints like poverty, malnutrition and infection. With an intention to study the problem of physical abuse in neglected children, patients admitted to the pediatric wards of our institution, predominantly with some form of physical abuse were specifically looked for from January 1976 onwards. Over a period of 4$\text{1}\text{2}$ years, 18 such cases were encountered. Most of the babies were less than four weeks of age, were predominantly females, were quite often premature or malnourished, and rarely had a physical deformity. These babies were deserted and later were found by police or social workers in gutters, dustbins, garbage tins, railway platforms, etc. The spectrum of abuse and injuries included newborn babies with intact placenta, at times lacerated, strangling marks on the throat, multiple bruises, bleeding from the umbilicus, avulsion of the scalp with severe bleeding, shock as a result of environmental stress (i.e., hypothermia), evidence of infection, rat bite marks, and fractures. The morbidity was very high, ultimately resulting in 88.9% mortality over varying periods of time, maximum survival being 22 days. The motive behind this abuse always was an unwanted baby.     

Rationality, Information Search and Choice in Higher Education: Evidence from Greece

The paper presents the findings of a study of the decision-making process which precedes the choice of a university in Greece. Specifically, the degree of rationality exhibited by prospective students is assessed in an attempt to provide a test for the economic approach to the explanation of human behaviour. Information search is used as an indication of rationality and measured through a survey conducted among 220 university students in the academic year 2003/2004. The findings provide weak support for the rationality postulate in that they indicate that more than 40% of respondents could not be classified as information seekers. Logistic regression analysis was used in order to identify characteristics associated with the propensity to engage in information search: high socioeconomic status students, students who perceived the decision as important, and students who had acquired information prior to the choice of a university were found to be more likely to engage in information search. The paper draws attention to the limitations of the economic rational man model of human behaviour and discusses the implications of the findings for the promotional strategy of universities.     

Influences on the intention to enter higher education: the importance of expected returns

Research points to several determinants of the private demand for higher education, which include individual, social, economic, and institutional variables. Of these variables, economic factors are considered to be highly relevant, especially in the current financial crisis. The paper investigates the link between expected rates of return to higher education and the intention of secondary education graduates to pursue university studies. The effect of additional variables influencing the choice of higher education (ability, gender, socioeconomic status [SES], type of secondary school, area of residence) is also examined. The findings show a significant link between the perceived rates of return and the intention of secondary school graduates to enter tertiary education. With the exception of residence, all independent variables are strong determinants of the intention to enter higher education. The paper also points to the considerable effect of the financial crisis on students’ expectations in that respondents reported lower perceived rates of return compared to previous estimates in the same country. The implications of the findings for higher education policy are discussed.
