The Relation Between Knowledge Of Adhd And Treatment Acceptability In A Multi-Disciplinary Pediatric Clinic, Rebecca Owen Currier Jan 2004

The Relation Between Knowledge Of Adhd And Treatment Acceptability In A Multi-Disciplinary Pediatric Clinic, Rebecca Owen Currier

LSU Doctoral Dissertations

Behavior modification and medication have been proven to be the most effective interventions for children with ADHD. For these treatments to be effective, utilization of mental health care services as well as compliance with treatment recommendations is necessary. There has been shown lower care utilization among minorities for the treatment of behavioral disorders. In addition, lack of adherence among these populations to ADHD treatment is not explained by SES, parenting stress, or family coping. An alternative explanation may be parental knowledge of ADHD and opinions of commonly used treatments. The present investigation examined the effect of a brief knowledge intervention …

Bakso (Traditional Indonesian Meatball) Properties With Postmortem Condition And Frozen Storage, Dino Rahardiyan Jan 2004

Bakso (Traditional Indonesian Meatball) Properties With Postmortem Condition And Frozen Storage, Dino Rahardiyan

LSU Master's Theses

Bakso is a finely comminuted boiled Indonesian meat product that is traditionally made of starch, salt and emulsified prerigor or early postmortem meat and often sold from street vendors. Recently processors have begun to commercially manufacture bakso. This research was conducted to investigate the substitution of early postmortem meat with postrigor meat to allow more efficient manufacturing and raw material procurement. The first experiment was to determine the properties of bakso with three tapioca starch concentrations added to early or late postmortem beef. No differences (p<0.05) were observed in bakso properties of composition and texture, though bakso made of post-rigor meat had slightly less elasticity, strength and shear. These disadvantages were compensated by incorporating 15% starch concentration, indicating that the replacement of early postmortem meat with postrigor meat was applicable in industrial mass production of bakso. The second phase of experiments was to investigate the properties of bakso with different frozen storage times of raw postrigor meat and after different times of frozen storage for bakso made from postrigor and early postmortem meat. Postrigor meat substitution for early postmortem meat in bakso with 15% tapioca starch resulted in minimum composition and textural differences (p>0.05). Meat stored frozen for 2 and 4 months was still suitable as raw …
