Abstract

This research aims to explore childhood construction in the Afghan refugee community living in Pakistan. Young Afghan people aged 12–18 who were working on the streets participated in the generation of data for this study in 2019. Ethnographic research approaches with semi-structured in-depth interviews and field observations were used to obtain real insights. Young Afghan refugees have been a constant phenomenon on the streets for decades in the twin cities of Pakistan – Rawalpindi and Islamabad – where this research was conducted and are involved in different street-based casual activities. The findings show that young people face discrimination and exclusion from the mainstream of society due to their undefined citizenship status and poverty. Parents see their children as dependents and as assets for their old age, and children and young people need to work to support their families who live in poverty. In fulfilling their filial responsibilities, young people sacrifice their schooling and have limited opportunities to learn new skills. It is concluded that the government and other international institutions with responsibility for setting policies and creating programs for young Afghan refugees need to understand the dynamics of the families in which the young people live and how these families inculcate them with their generational values.

Abstract

Purpose – The purpose of this research is to synthesize modified thermoplastic sago starch (TPS) through in-situ mechanism by reacting sago starch with diphenylmethanediisocyanate (MDI) and castor oil simultaneously, resulting in a more homogenous and finer-sized polyurethane prepolymer (PUP).

Design/Methodology/Approach – The methods used were Thermal Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) for thermal characterization and stability of PUP, modified TPS non-extracted and extracted with toluene and water.

Findings – TGA test results presented shows that PUP begins to decompose thermally at a temperature of 300–500 °C. Weight loss occurs rapidly between these temperatures and is completely discharged at a temperature of 500°C, which is called weight loss transition.

Research Limitations/Implications – When extracted with toluene and a water solvent, the melting point and latent heat of fusion slightly decreased; however, it is still higher than the original value of sago. In terms of thermal stability, modified TPS decomposes and loses weight at 150–200 °C in small quantities, continues with weight loss rapidly, and is completely discharged at 500°C. The thermal stability is considered high; thus, modified TPS application can be varied.

Practical Implications – DSC analysis and TGA shows that modified TPS has good thermal characteristics and thermal stability. Modified TPS has a melting point of 104.69°C, and the latent heat of fusion (ΔH) is 234.27 J/g. This value is close to the PUP melting point and latent heat of fusion, which reveals the formation of cross-link between the starch and PUP.
