The effect of information system resources and information system capability of organization in post war Sri Lankan context

In recent years, the role of information system has grown in importance. Thus, Information System(IS) is evolving into key part of a company's performance and this paper provides an analysis on the relationship between Information system resources and Information system capability in Sri Lankan Context; the basic idea is that a firm's IS capability can be explained by how effective the firm is in using IS resources to exchange Capability . Therefore, this concept developed "effect of IS Resources and IS Capability of organization. This study is empirically tested using data collected from IT managers or executives from IT department or IT unit from 46 firms in Colombo metropolitan area in Sri Lanka. Information technology infrastructure capabilities have been noted in prior research as having a significant impact on firm performance. However, it is not clear how these infrastructures meant and impact on IS capability and past study have implicitly assumed that IS assets could have direct influence on firm performance. This paper examines how effective the relationship is being between IS Resources and IS Capability. IS Resources include Information System Human Capital (ISHC) and Information Technology Infrastructure (ITI) and IS capability includes IS Planning, System Development Capability, IS Support System, and IS Operations Capability. Structured questionnaire was included in the questionnaire with S points likert scale. Data analysis was done using correlation. Person's correlation coefficient was used to measure the linear relationship between variables. This results provide evidence that IS Human Capital has positive significant effect on IS capability than IT Infrastructure has positive significant effect on capability. These results have significant implication for future research and practice on how IS Resources and ARE capability contributed development of business and enhancement of firm performance

Acute Administration of Clozapine and Risperidone Altered Dopamine Metabolism More in Rat Caudate than in Nucleus Accumbens: A Dose-Response Relationship

The present study compares the extrapyramidal and neurochemical effects of clozapine and risperidone in rat caudate (corpus striatum) and nucleus accumbens (ventral striatum) dose-dependently. Animals injected with clozapine (2.5, 5.0 and 10.0 mg/kg IP) or risperidone (1.0, 2.5 and 5.0 mg/kg IP) in acute were sacrificed 1 h later to collect brain samples. Extrapyramidal side effects (EPS) in terms of locomotor activity and catalepsy were monitored in each animal after the drug or vehicle administration. Maximum cataleptic potentials were found only at high doses of clozapine (10.0 mg/kg; 60%) and risperidone (5.0 mg/kg; 100%). Neurochemical estimations were carried out by HPLC-EC. Both drugs at all doses significantly (p<0.01) increased the concentration of homovanillic acid (HVA), a metabolite of DA, in the caudate nucleus and decreased in nucleus accumbens. Levels of Dihydroxyphenylacetic acid (DOPAC) significantly (p<0.01) increased in the caudate by clozapine administration and decreased in the nucleus accumbens by the administration of both drugs in a dose-dependent manner. 5-Hydroxyindoleacetic acid (5-HIAA), the predominant metabolite of serotonin significantly decreased in the caudate and nucleus accumbens in a similar fashion. Levels of tryptophan (TRP) were remained insignificant in caudate and nucleus accumbens by the injections of two drugs. In caudate, clozapine and risperidone administrations significantly (p<0.01) decreased HVA/DA ratio and increased DOPAC/DA ratio in nucleus accumbens at all doses. The findings suggest the evidence for DA/5-HT receptor interaction as an important link in the lower incidence of EPS. The possible role of serotonin1A receptors in the pathophysiology of schizophrenia is also discussed

Estimation of Export Supply Function for Citrus Fruit in Pakistan

There is strong evidence in the literature that export and economic growth have a positive relationship. In Pakistan, with an agrarian economy, earnings from primary agricultural exports are vital for the overall growth process. Fruits are the traditional export commodities, which contribute more than half of total export earnings from primary agricultural commodities. The persistent instability in world market prices for primary commodities has depressed the export earnings from these commodities over time. This poses great challenges to a country like Pakistan. The present study aims at examining changes in the volume of export of citrus fruit from Pakistan caused by such factors as changes in domestic and export prices, national product, foreign exchange rate, etc. The study uses time series data for the period 1975–2004 for citrus exports and related domestic price, export price, GDP, and foreign exchange rate, employing the co-integration and error correction techniques for analysis purposes.

NO SUCH STATE AS PALESTINE: NOTIONS OF HOME AND THE STATE IN PALESTINIAN RELATIONSHIPS WITH PALESTINE

There is no such state as Palestine. But nearly 70 years after the termination of the British mandate for Palestine and the creation of the state of Israel, Palestine remains a home for the Palestinian. It is an identity not dependent on the existence of a Palestinian state, nor arrested by the presence of an Israeli one. Palestinians have a home relationship with Palestine, where home is a sense of belonging that comes from within, that isn’t earned and given, but personal and chosen, even while it is communal. Home is a self-determined relationship of person to place. The relationships of Palestinians with Palestine are complicated and inconsistent, but I contend that the complications and inconsistencies of understanding Palestine as home functions as a spatial strategy of holding out for justice. Where home is an intensely personal attachment with effects that vary between individuals, the nation-state seeks to create a matrix relationship between nations and territories that defines those who belong to the exclusion of all others. The persistence of Palestinian home relationships with Palestine stand argument against a nation-state world order founded on the idea that certain people belong natively to certain place

Oilfield Produced Water Management: Treatment, Reuse and Disposal

Produced water is accompanied with the production of oil and gas especially at the fields producing by water drive or water injection. The quantity of these waters is expected to be more complicated problem with an increasing in water cut which is expected to be 3-8 barrels water/produced barrel oil.Produced water may contain many constituents based on what is present in the subsurface at a particular location. Produced water contains dissolved solids and hydrocarbons (dissolved and suspended) and oxygen depletion. The most common dissolved solid is salt with concentrations range between a few parts per thousand to hundreds parts per thousand. In addition to salt, many produced waters also contain high levels of heavy metals like zinc, barium, chromium, lead, nickel, uranium, vanadium and low levels of naturally occurring radioactive materials (NORM).This study will highlight the main aspects of the different international experiences with the produced water treatment for subsequent reuse or disposal. These different treatment methods vary considerably in effectiveness, cost and their environmental impacts. Samples of produced water from Al-Mishrif formation in ten wells belongs to five fields southern Iraq were taken and analyzed chemically to define the basic features of these waters and to have guide lines for the best strategy that required handling the increased water cut in these fields

Profile and risk factors for congenital heart disease

Congenital heart disease is an important cause of infant mortality and disability. The frequency, spectrum and contributory risk factors for significant cardiovascular malformations among live-births was retrospectively evaluated at the Aga Khan University Hospital. Of a total of 8331 live births between July, 1987 and December, 1992 34 babies were diagnosed to have congenital heart disease in the neonatal period giving a prevalence of 4 per 1000 live births. Ventricular septal defects was the most common (n = 10, 29%) abnormality. Eight cases had associated chromosomal abnormality, the most common being Trisomy 21. Maternal abortions, still-births, consanguinity and diabetes mellitus were not found to be significant risk factors for congenital heart disease in this survey

Estimation of Export Supply Function for Citrus Fruit in Pakistan

Nature has blessed Pakistan with an ideal climate for growing a wide range of delicious fruits. Thus a very wide range of tropical, sub-tropical and temperate fruits are grown in the country. Over the years, Pakistani experts have developed unique strains of exotic fruit varieties. Pakistan is producing a large variety of fruits on an area of 734.6 thousand hectares with a total production of 5712.4 thousand tons. Out of this 354.4 thousand tons fruit is exported from the country [Pakistan (2004)]. Horticulture is an important sub-sector of agriculture and plays a vital role not only in rejuvenation of rural economy but also in improving human nutrition which is often deficient in ingredients such as vitamins and minerals. Citrus and mango are the main fruit crops which contribute substantially to the national income
