Determinants of Internal Migration in Pakistan: Evidence from the Labour Force Survey, 1996-97

The process of migration has diverse economic, social and environmental implications for the places of origin and destination. In the context of balanced regional growth and sustainable regional development it is important to study how internal migration affects the patterns of population distribution within a country. The spatial distribution of population is influenced by the characteristics of the sending and receiving areas in terms of push and pull factors resulting in rural-urban, urban-urban, rural-rural and urban-rural migration flows. As economies transform from being predominantly rural to being predominantly urban societies, the process of urbanisation assumes a rapid pace. Individuals migrate from rural to urban areas as a rational human capital investment decision to reap economic rewards in the form of better economic opportunities and benefits. The consequences of rapid urbanisation are multi faceted and require timely responses by development planners and policy-makers to deal with pressures created on the infrastructure of large urban centres by the influx of migrants. However, in some developing as well as developed countries, lately, there have been signs of a change in the trend of the population distribution away from concentration in a few large cities towards a more widespread distribution in medium-sized urban centres. The other dimension of this rural-urban migrant outflow manifests itself in the changing labour market scenario in the rural economy which loses the more productive members of its labour force to the urban economy.

Exports, Growth and Causality: An Application of Co-integration and Error-correction Modelling

The relationship between export expansion and economic growth has been examined extensively during the last two decades in the context of the suitability of the alternative development strategies. The decade of the 1970s witnessed an emerging consensus in favour of export promotion as development strategy. Such a consensus was based on the following facts. First, higher export earnings working through alleviating foreign exchange constraints may enhance the ability of a developing country to import more industrial raw materials and capital goods, which, in turn, may expand its productive capacity. Secondly, the competition in export markets abroad may lead to the exploitation of economies of scale, greater capacity utilisation, efficient resource allocation, and an acceleration of technical progress in production. Thirdly, given the theoretical arguments mentioned above, the observed strong correlation between exports and economic growth was interpreted as empirical evidence in favour of export promotion as a development strategy.

Expanded inverted repeat region with large scale inversion in the first complete plastid genome sequence of Plantago ovata

Plantago ovata (Plantaginaceae) is an economically and medicinally important species, however, least is known about its genomics and evolution. Here, we report the first complete plastome genome of P. ovata and comparison with previously published genomes of related species from Plantaginaceae. The results revealed that P. ovata plastome size was 162,116 bp and that it had typical quadripartite structure containing a large single copy region of 82,084 bp and small single copy region of 5,272 bp. The genome has a markedly higher inverted repeat (IR) size of 37.4 kb, suggesting large-scale inversion of 13.8 kb within the expanded IR regions. In addition, the P. ovata plastome contains 149 different genes, including 43 tRNA, 8 rRNA, and 98 protein-coding genes. The analysis revealed 139 microsatellites, of which 71 were in the non-coding regions. Approximately 32 forward, 34 tandem, and 17 palindromic repeats were detected. The complete genome sequences, 72 shared genes, matK gene, and rbcL gene from related species generated the same phylogenetic signals, and phylogenetic analysis revealed that P. ovata formed a single clade with P. maritima and P. media. The divergence time estimation as employed in BEAST revealed that P. ovata diverged from P. maritima and P. media about 11.0 million years ago (Mya; 95% highest posterior density, 10.06-12.25 Mya). In conclusion, P. ovata had significant variation in the IR region, suggesting a more stable P. ovata plastome genome than that of other Plantaginaceae species.publishedVersio

This paper investigates Arabic and English morphemes with to identifying the similarities and differences between them. The differences between the two languages might be the main reason for making errors by Arab learners. It might help both teachers and learners to overcome these problems. By identifying the morphological differences between the two languages, teachers will determine how and what to teach, on the one hand, and students will know how and what to focus on when learning the target language, on the other. The Paper will shed light on phonological terms such as: "phonem, allophones, intonation, and accentuation" and their equivalents in English in order to identify the appropriate or opposing signs that affect the specificity of the sounds. We have followed the descriptive and analysis research methods. The results of study on morphemes have an interrogative and exclamatory function, and we find that the morpheme “what” is distinguished from the morpheme “ما”, which has other uses such as negation, infinitive, extra and accentuation

The dynamic history of gymnosperm plastomes: Insights from structural characterization, comparative analysis, phylogenomics, and time divergence

Gymnosperms are among the most endangered groups of plant species; they include ginkgo, pines (Conifers I), cupressophytes (Conifers II), cycads, and gnetophytes. The relationships among the five extant gymnosperm groups remain equivocal. We analyzed 167 available gymnosperm plastomes and investigated their diversity and phylogeny. We found that plastome size, structure, and gene order were highly variable in the five gymnosperm groups, of which Parasitaxus usta (Vieill.) de Laub. and Macrozamia mountperriensis F.M.Bailey had the smallest and largest plastomes, respectively. The inverted repeats (IRs) of the five groups were shown to have evolved through distinctive evolutionary scenarios. The IRs have been lost in all conifers but retained in cycads and gnetophytes. A positive association between simple sequence repeat (SSR) abundance and plastome size was observed, and the SSRs with the most variation were found in Pinaceae. Furthermore, the number of repeats was negatively correlated with IR length; thus, the highest number of repeats was detected in Conifers I and II, in which the IRs had been lost. We constructed a phylogeny based on 29 shared genes from 167 plastomes. With the plastome tree and 13 calibrations, we estimated the tree height between present-day angiosperms and gymnosperms to be ∼380 million years ago (mya). The placement of Gnetales in the tree agreed with the Gnetales–other gymnosperms hypothesis. The divergence between Ginkgo and cycads was estimated as ∼284 mya; the crown age of the cycads was 251 mya. Our time-calibrated plastid-based phylogenomic tree provides a framework for comparative studies of gymnosperm evolution.publishedVersio

To evaluate the role of pentoxifylline in optic atrophy induced by tuberculosis

A 30 year female, presented two years back with complaint of gradual loss of vision in L/E followed by poor vision in R/E and she was diagnosed as having miliary tuberculosis and taken complete ATT. Patient was started on pentoxifylline 400 mg twice daily and observed after 15 days. There was rapid improvement in vision. Patient was followed up at every month for first three months and then every three monthly for two years. For this patient, treatment with oral pentoxifylline 400mg twice daily for two years led to improvement in visual acuity. The improved visual acuity in this patient suggests that pentoxifylline is an effective treatment of optic atrophy of eye in the patients with tuberculosis

Structure, Genetics and Worldwide Spread of New Delhi Metallo-β-lactamase (NDM): a threat to public health

Background: The emergence of carbapenemase producing bacteria, especially New Delhi metallo-β-lactamase (NDM-1) and its variants, worldwide, has raised amajor public health concern. NDM-1 hydrolyzes a wide range of β-lactam antibiotics, including carbapenems, which are the last resort of antibiotics for the treatment of infections caused by resistant strain of bacteria. Main body: In this review, we have discussed blaNDM-1variants, its genetic analysis including type of specific mutation, origin of country and spread among several type of bacterial species. Wide members of enterobacteriaceae, most commonly Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, and gram-negative non-fermenters Pseudomonas spp. and Acinetobacter baumannii were found to carry these markers. Moreover, at least seventeen variants of blaNDM-type gene differing into one or two residues of amino acids at distinct positions have been reported so far among different species of bacteria from different countries. The genetic and structural studies of these variants are important to understand the mechanism of antibiotic hydrolysis as well as to design new molecules with inhibitory activity against antibiotics. Conclusion: This review provides a comprehensive view of structural differences among NDM-1 variants, which are a driving force behind their spread across the globe
