The effects of particle size of collagen and mold material on the pore structure of freeze-dried collagen-GAG scaffolds

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2007.Includes bibliographical references (p. 25).This study was performed to determine whether the particle size of the starting collagen powder or the material of molds used during freeze-drying had effects on the scaffold pore structure. Collagen particles were separated by size prior to slurry making using a sieve with 1000 [mu]m openings, and scaffolds were made using both metal pans and polysulfone trays, two commonly used molds. The mean and variation of pore diameter and interconnectivity of freeze-dried scaffolds were compared to determine the relationship between particle size or mold material and the resulting pore diameter, for a specific same freeze-drying condition (viz., temperature). Knowing these relationships will permit a better control of pore size during fabrication, allowing researchers to design scaffolds with greater predictability and specificity.by Jenny K. Chan.S.B

Suicide as Protest for the New Generation of Chinese Migrant Workers

A startling 13 young workers attempted or committed suicide at the two Foxconn production facilities in southern China between January and May 2010. We can interpret their acts as protest against a global labor regime that is widely practiced in China. Their defiant deaths demand that society reflect upon the costs of a state-promoted development model that sacrifices dignity for corporate profit in the name of economic growth. Chinese migrant labor conditions as articulated by the state, are shaped by these intertwined forces: First, leading international brands have adopted unethical purchasing practices, resulting in substandard conditions in their global electronics supply chains. Second, management has used abusive and illegal methods to raise worker efficiency, generating widespread grievances and resistance at the workplace level. Third, local Chinese officials in collusion with enterprise management, systematically neglect workers' rights, resulting in widespread misery and deepened social inequalities. The Foxconn human tragedy raises profound concerns about the working lives of the new generation of Chinese migrant workers. It also challenges the state-driven policy based on the use of internal rural migrant workers, whose labor and citizenship rights have been violated. Key words: suicide, protest, new generation of migrant workers, global labor regime, migrant wages, electronics manufacturing service (EMS) industry, Foxconn, international brands, citizenship, China To die is the only way to testify that we ever lived Perhaps for the Foxconn employees and employees like us – we who are called nongmingong, rural migrant workers, in China – the use of death is simply to testify that we were ever alive at all, and that while we lived, we had only despair. - a worker blo

Smart Motor Syringe System

Syringe pumps are widely used in many research applications especially in the applications that need precise control. Today most medical research utilizes syringes to control the fluid being pumped to the experiment objects. In most cases microscopic or nano-scopic motion control is required to acquire optimal results, such application includes purification of DNA/RNA from contaminants[1]. The high precision required to control the syringe pump makes it difficult to perform manually. This paper focuses on the design of an intelligent syringe pump motor control system to achieve reliable and precise control for biomedical experiments. This project improves medical research quality with the development of a high precision, digital controlled multi unit syringe pump. The “Smart” motor syringe pump will be capable of delivering fluids in constant flow rate in high precision. The feature includes a graphic user interface on the computer for system control. The system will have functions such as volumetric flow rate adjustment under medical research conditions

Critical Pedagogies of Place: Some Considerations for Early Childhood Care and Education in a Superdiverse ‘Bicultural’ Aotearoa (New Zealand)

National education policy must respond to demographic changes.  In Aotearoa (New Zealand), recent immigration policy changes have resulted in the new challenge of superdiversity, which is overlaid in a bicultural context of the longstanding impacts of the colonisation of the Indigenous Māori.  The lack of equity in this ‘bicultural’ arrangement remains to be fully resolved due to the dominance of the settler culture. The early childhood care and education sector requires of its teachers a deep cultural understandings of and engagement with all those children and families present in the education settings. This article provides a discussion of the dilemma of superdiversity faced by a ‘bicultural’ education policy environment. It then describes the results of a study that utilised a process of documentary analysis to critically examine the macro- and micro-level policy statements and reports with regard to bicultural and cultural diversity matters in early childhood care and education settings in Aotearoa (New Zealand).   The implications of the findings point to challenges faced by teachers when translating policy commitments into pedagogical enactment. The findings suggest that it is important for teachers to not only engage deeply with the Indigenous Māori language, culture, and local histories of connectedness with place, but that this engagement should also be made available to immigrant children and families.  Teachers can engage with immigrant families’ important stories and histories of connectedness to the special places of their homelands.  The paper concludes with discussion of recommendations regarding the need for both pre-service and in-service education for teachers in relation to these important issues of equity, social justice, culture, diversity and place-connectedness
