Globalization and Education
No full textThe concept of globalization has been introduced due to technical advancements that has made the world a global village. The world as is now has never been before; it is now a world where multicultural societies have developed, trade and transactions are made between countries, technology reaches every part of the world, and internet has connected every possible idea, opinion, person, and commodity with the rest of the world. In this world of globalization, education has taken a central role, as without education globalization cannot be germinated. Education is a national issue and as such, each country has its own educational policies that are emblems of that country's cultural values, belief system and historical realities. Nevertheless, the globalized world demands for multiculturalism, and commonalities amongst communities to be promoted so as to bring the world closer to accepting cultural diversities and celebrating commonalities. For these aims, educational institutions become institutions for promoting globalization by introducing various cultural and traditional beliefs to the new generation.
Recently, globalization has become a popular subject of debate in national and international circiles. Globalization links individuals and institutions across the world through economic forces, digital technologies, and communication. It is moreover subjected to higher living standards, international affiliations, and multiple types of freedom. However, a major part of the world consists of under developed countries where technological advancements, communication, trade and commerce along with other economic activities are not enough to support them to be a part of the global society

Effect of Climate Change and Human Activities on Surface and Ground Water Quality in Major Cities of Pakistan
No full textIn this study, climate change and human impacts on water quality in five major urban areas of Pakistan, including Karachi, Lahore, Peshawar, Abbottabad, and Gilgit, were determined. Secondary data on various physical, chemical, and bacteriological water quality parameters were taken from published papers, reports, and theses. Surface and groundwater were the major sources of drinking water in these cities. The physicochemical parameters were total turbidity, pH, dissolved solids (TDS), sulphates, chlorides, calcium, sodium, HCO3, potassium, magnesium, nitrates, fluorides, arsenic, and hardness. The bacteriological parameters were total coliform, total faecal coliform, and total plate counts. The data revealed that pH, TDS, fluoride, chloride, HCO3, sodium, and hardness were above the limits in Karachi. MCB Market, Goth Ibrahim, and Malir Town were the main contaminated areas in Karachi. In Lahore, arsenic was found above the limits in all sampling locations. Turbidity, pH, HCO3, calcium, magnesium, and hardness were found above the limits in Peshawar. In Gilgit city, all physicochemical parameters were found within the limits except turbidity, which was 10 NTU in Nomal valley. Nitrates were higher in the water sources in Abbottabad. Bacterial contamination was found in the water of all five cities. Most of the studies revealed that this contamination could be human-induced. The improper disposal of solid waste, sewage, and animal waste and the excessive use of fertilisers deteriorate the quality of the water. Precipitation, a rise in temperature, and seasonal variation are climate variables that affect water quality and are responsible for major outbreaks of waterborne diseases. There is an urgent need for regular analysis, proper management, and proper treatment of drinking water before it is supplied to the local community in these cities
A prospective hospital based study of relation between carotid artery intimal medial thickness in patients with type 1 diabetes
Full text linkBackground: The aim of this study was to found association between Type 1 Diabetes Mellitus and Carotid Arterial Intimal Thickness (CIMT).Methods: Study design: It was a prospective case control hospital-based study. One hundred type 1 diabetes patient between the age group 3-36 years were taken. The association between type 1 diabetes with CIMT was studied. All the measurements were standardized. 50 age and sex matched controls were taken for comparison.Results: There is positive correlation between type 1 diabetes and CIMT (p<0.0001). The correlation further extends between duration of diabetes, glycemic control, age of onset, frequency and severity of diabetic related complication with CIMT.Conclusions: Carotid atherosclerosis as measured by CIMT has definite association with type 1 diabetes
Process optimization of polyphenol extraction from carob (Ceratonia siliqua) kibbles using microwave-assisted technique
No full text© 2017 Wiley Periodicals, Inc. Microwave-assisted extraction (MAE) method was investigated to recover phenolic compounds from carob kibbles and validated using response surface methodology. The study parameters were microwave power (170–900 W), ethanol concentration (30–90%), and solvent-to-sample ratio (10–30 mL/g) in terms of total phenolic content (TPC) and condensed tannins. Among optimized parameters (340 W, 45%, 30 mL/g), microwave power and ethanol concentration were found more influential parameters to get higher yields of TPC and condensed tannins. Moreover, the results of TPC (70.11 mg GAE g-1 DM), condensed tannins (4.11 mg CE g-1 DM), free radical scavenging activity (94.42%), ferric ion reducing potential (22.67 mg Fe+3 100 g-1 DM), and gallic acid (1.576 mg/g DM) obtained from optimal MAE conditions were found comparable to ultrasound-assisted extraction method. The newly developed MAE method illustrates its potential to recover phenolic compounds from plant sources in a short duration. Practical applications: Based on the results presented in this work, it is proposed that carob kibble could be considered as interesting raw material to get extracts rich in antioxidant properties. This extract could be used as an alternative to synthetic antioxidants in bio-food products as natural preservative. Therefore, carob kibbles could be recommended for production of extracts rich in antioxidants, instead of being discarded from gum factory as by-product. In addition, microwave-assisted extraction method could be employed to increase time efficiency of the process
Transitional bilingualism : a study of the language experience of some families of Pakistani origin living in Britain
Full text linkThis thesis examines the bilingualism of nine families of Pakistani origin living in England,
to gain an understanding of their experience of living through a period of rapid
intergenerational language change. The families are all linked to the medical profession
and the second generation are educationally successful. The study aims to gain insights
into the social and linguistic processes of language shift. It also aims to contribute to
understanding of the position of successful ethnic minority young people.
Qualitative research methods are used, including interviews and participant observation
and analysis of data is interpretive. A corpus of language use is analysed, focusing on
intergenerational interaction and code-switching. Discussion of educational issues draws
on policy documents.
The fIrst three chapters constitute the preliminary section of the thesis. They present the
research group, the social, linguistic and educational contexts, a theoretical framework
and a critical description of the methodological evolution of the study.
Chapters four to nine are data-based and focus on different aspects of the families'
bilingualism. Accounts of early language nurture are analysed; bilingual skills and
repertoires are investigated and the relationship between linguistic and cultural continuity
is explored. A study of in-family bilingual interaction is presented and language education
policy and its relevance to family concerns is considered.
The study draws coherence from recurring themes, and insights into the experience of
transitional bilingualism. Concern for educational success emerges strongly. The different
signifIcance of using the minority languages inside the family and outside is revealed and
the importance of long-term developments and cultural continuity is clear. Language
education policies do not always reflect the priorities of the families.
The linguistic situation of the families is very unstable but individuals may well take up
very different intellectual positions in relation to their linguistic future
