Articulation of medium of instruction politics in the Malaysian Chinese press

In postcolonial multilingual societies, matters of education are deeply rooted in the discourse of ethnicity. In Malaysia, the interface between ethnicity and education is reflected in recent debates on the choice of medium of instruction (MOI). In 2002, the Malaysian government introduced English as MOI by replacing Malay, the national language, for teaching mathematics and science, at the school level. However, in 2009, the policy was reversed to Malay. This policy initiative has been actively contested in the Malaysian media. Through an analysis of news reports on the controversy published by the Malaysian Chinese newspaper, Nanyang Siang Pao, this paper aims to illustrate how a sizeable ethnic minority is able to position itself vis-à-vis a national policy. To explain the ethno-political construction of MOI debates in the newspaper, we use two concepts, namely, ‘plurality of struggles’ (Laclau, 2006a, 2006b; Laclau & Mouffe, 1985) and ‘transmission of the speech of others’ (Bakhtin, 1981). These notions are contextualized in the macro-context of a multi-ethnic polity in which Chinese society, Chinese press and Chinese education are seen to co-construct community interests.

Bistability in droplet traffic at asymmetric microfluidic junctions

We present the first experimental demonstration of confined microfluidic droplets acting as discrete negative resistors, wherein the effective hydrodynamic resistance to flow in a microchannel is reduced by the presence of a droplet. The implications of this hitherto unexplored regime in the traffic of droplets in microfluidic networks are highlighted by demonstrating bistable filtering into either arm of symmetric and asymmetric microfluidic loops, and programming oscillatory droplet routing therein.     

Successful immunological treatment of gallbladder cancer in India Case report

Gallbladder cancer has a poor outcome because of its anatomy and location. Often, the diagnosis is made very late due to its silent course. Post-operated cases do respond to chemotherapy but the survival is counted in months and the quality of life is further hampered due to toxicity of drugs. Immunotherapy holds good promise in non-responding cancers treated by conventional chemotherapeutic agents. Among various therapies, dendritic cell therapy is growing at rapid pace due to its acceptable rationale. It has been utilized in treating successfully resected stage Ill （T2, N1, M0） gallbladder cancer in one of our patients. A 48 years old lady treated with this therapy is free of metastasis with ten doses of autologous dendritic cell vaccine constructed by utilizing resected tumor lysate antigen. She has received ten doses of therapy in 14 months of her treatment. This therapy has proven to be safe and without apparent side effects. The positive clinical response obtained supports that autologous dendritic cell-based immunotherapy is a promising therapeutic approach for refractory gallbladder cancers.     

Delinquency and reputational orientations of adolescent at‐risk and not‐at‐risk males and females

This research investigated differences in delinquent activities and the reputational orientations of at‐risk and not‐at‐risk male and female adolescents. Initially, we sought to establish that adolescent males and females differed in these respects. This was found to be the case: males (n = 722) scored significantly higher than females (n = 738) on seven self‐reported delinquency variables and on eight reputation enhancement variables pertaining to social deviance, non‐conforming reputation, and power/evaluation private identity. When a sample of 31 at‐risk females was subsequently pair‐wise age matched with 31 not‐at‐risk females, at‐risk females scored significantly higher on all delinquency variables other than school misdemeanors. These at‐risk females also scored significantly higher on four reputation enhancement variables relating to social deviance and non‐conformity. Given that at‐risk females did not differ from their not‐at‐risk counterparts in level of involvement in school misdemeanors, we sought to determine whether this was also the case for at‐risk and not‐at‐risk males. An age‐matched sample of 91 pairs revealed that at‐risk males reported significantly higher involvement than not‐at‐risk males in all aspects of delinquency, including school misdemeanors. They also sought a more non‐conforming reputation. To explore the relationships between delinquency and reputation enhancement, a canonical correlation analysis was performed. All findings are discussed in the light of reputation enhancement theory.     

Assessing teachers’ multicultural and egalitarian beliefs: The Teacher Cultural Beliefs Scale

The article describes the newly developed Teacher Cultural Beliefs Scale (TCBS). The TCBS assesses multicultural and egalitarian beliefs about diversity, both of which reflect favorable attitudes toward immigrant students, but differ with regard to how cultural diversity is believed to be best accommodated in schools. Results from a first study with 433 beginning teachers supported the two-factor structure and the measurement invariance of the scale. Results from a second study with 340 teacher candidates and educational science students showed that proponents of multiculturalism and egalitarianism shared a motivation to control prejudiced reactions, but that they differed in their views on acculturation, prejudices, and authoritarianism.     

Oral reading fluency and comprehension in Kenya: reading acquisition in a multilingual environment

Reading research has shown that variable relationships exist between measures of oral reading fluency and reading comprehension, depending on whether the language of the text is the reader's first language or an additional language. This paper explores this phenomenon, using reading assessment data for 2,000 Kenyan children in two or three languages: English, Kiswahili and one of two mother tongues, Dholuo or Gikuyu. The assessment data allowed us to compare reading and comprehension rates across languages. The data indicated that many children could read English words more easily than words in Kiswahili or their mother tongue; nevertheless, their reading comprehension was significantly lower in English than in Kiswahili, Dholuo or Gikuyu. The paper concludes that emphasising English reading fluency is an inefficient route to gaining reading comprehension skills because pupils are actually attaining minimal oral reading fluency in English and only modest comprehension skills in their own languages. The evidence also demonstrates that Kenya's national language policy of mother tongue as a medium of instruction in the early primary grades is consistently ignored in practice.     

Expanding the Learning Network: How Teachers Use Pinterest

This exploratory qualitative study of 117 teachers explores how educators engage with Pinterest, an online social networking site, specifically asking: (1) What similarities and differences exist in how elementary-level preservice and elementary-level in-service teachers engage with Pinterest? (2) What similarities and differences exist in how secondary-level in-service teachers and elementary-level in-service teachers engage with Pinterest? Findings indicate teachers at all levels tend to use Pinterest to search for educational resources and adapt resources to suit their classroom needs. Preservice teachers identify a more complex interaction with Pinterest than in-service teachers when determining quality resources. Findings indicate a need for future research into teacher education practices and the complex interactions preservice teachers engage in with Pinterest resources.     

Phytochemical composition,biological potential and enzyme inhibition activity of <Emphasis Type="Italic">Scandix pecten-veneris</Emphasis> L.

Objective

Scandix pecten-veneris L. is a less studied wild edible herb and is considered an extinct plant species in many parts of the world. This study was designed to evaluate its phytochemical composition and biological potential of S. pecten-veneris L.

Methods

Phytochemicals including alkaloids, flavonoids, polyphenols, and tannins were determined in extracts of S. pecten-veneris. Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), while reducing power was tested by ferric reducing/antioxidant power (FRAP) assay. Antimicrobial activity against seven bacterial and four fungal strains was evaluated using agar well diffusion assay. Enzymes inhibition study was performed for urease, phosphodiesterase-I, and catalase-II.

Results

S. pecten-veneris showed moderate antiradical activity and reducing potential of hydroxyl radicals to about 20% of the initial value. The antioxidant activity of various extracts of S. pecten-veneris showed a linear correlation with total phenolic contents in the order of water>n-butanol>chloroform>ethyl acetate>methanol extracts. S. pecten-veneris leaves showed the highest inhibitory activity against Staphylococcus aureus while the highest antifungal activity was observed against Candida albicans. The plant extract was most potent against urease enzymes but showed moderate activity against phosphodiestrase-I and carbonic anhydrase-II.

Conclusions

Our data demonstrate that in addition to its culinary uses, S. pecten-veneris has good medicinal potential and hence could be used for treating some specific health ailments.

     

Quality of effluents from Hattar Industrial Estate

Of 6634 registered industries in Pakistan, 1228 are considered to be highly polluting. The major industries include textile, pharmaceutical, chemicals （organic and inorganic）, food industries, ceramics, steel, oil mills and leather tanning which spread all over four provinces, with the larger number located in Sindh and Punjab, with smaller number in North Western Frontier Province （NWFP） and Baluchistan. Hattar Industrial Estate extending over 700 acres located in Haripur district of NWFP is a new industrial estate, which has been developed with proper planning for management of industrial effluents. The major industries located in Hattar are ghee industry, chemical （sulfuric acid, synthetic fiber） industry, textile industry and pharmaceuticals industry. These industries, although developed with proper planning are discharging their effluents in the nearby natural drains and ulti- mately collected in a big drain near Wah. The farmers in the vicinity are using these effluents for growing vegetables and cereal crops due to shortage of water. In view of this discussion, there is a dire need to determine if these effluents are hazardous for soil and plant growth. So, effluents from different industries, sewage and normal tap water samples were collected and analysed for pH electrical conductivity （EC）, total soluble salts （TSS）, biological oxygen demand （BOD）, chemical oxygen demand （COD）, total nitrogen, cations and anions and heavy metals. The effluents ofghee and textile industries are highly alkaline. EC and TSS loads of ghee and textile industries are also above the National Environmental Quality Standards （NEQS）, Pakistan. All the effluents had residual sodium carbonates （RSCs）, carbonates and bicarbonates in amounts that cannot be used for irrigation. Total toxic metals load in all the effluents is also above the limit i.e. 2,0 mg/L. Copper in effluents of textile and sewage, manganese in ghee industry effluents and iron contents in all the effluents were higher than NEQS. BOD and COD values of all the industries are also above the NEQS. On the whole, these effluents cannot be used for irrigation without proper treatment otherwise that may cause toxicity to soil, plants and animals as well add to the problems of salinity and sododicity. Similarly, these effluents cannot be used for fish farming.
