title: The effects of schedule volatility on supply chain performance

authors: Childerhouse, Paul

subjects: supply chain management

abstract: Schedule volatility is an unfortunate fact of life facing most suppliers of both products and services. In this paper, we are concerned with establishing the magnitude of the problem faced and the resultant effects on supply chain performance. Empirical data collected from 59 value streams are statistically analysed to investigate the negative effects of volatile customer schedules on performance. The evidence has been acquired predominantly via the rigorous site-based Quick Scan Audit Methodology. For each value stream, the forecast error is evaluated, which confirms the excessive volatility of the orders placed by many customers. A comparison between the automotive and non-automotive supply chains is conducted to assess the generic nature of the resultant relationships. We have concluded that volatility is a universal problem not confined to particular industries. Hence it strengthens the viewpoint that solutions initially proposed for the automotive sector may well find successful application elsewhere.

title: Investigating the effectiveness of teaching methods based on a four-step constructivist strategy

authors: Calik, Muammer

subjects: alternative conception

abstract: This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade 9 classes in the city of Trabzon, Turkey. Data collection employed a purpose-designed ‘solution chemistry concept test’, consisting of 17 items, with the quantitative data from the survey supported by qualitative interview data. The findings suggest that using different methods embedded within the four-step constructivist-based teaching strategy enables students to refute some alternative conceptions, but does not completely eliminate student alternative conceptions for solution chemistry.

title: Art, the aesthetics, and ethics of tattooing at Flax Roots Tattoo Studio

authors: Shaver, Mandy (Amanda)

subjects: aesthetic

abstract: Flax Roots Tattoo Studio, a tattoo business in Hamilton, Waikato, New Zealand, offers clients different styles of tattooing to choose from, i.e. Moko, Traditional European, Portrait, and Traditional American. Tattoo artists and their clients differ in ethnicity, nationality, religion, sex, occupation, age, hobbies, and so on.  Anthropological research and philosophical insight provided the framework texts for my case study.  My fieldwork consisted of semi-structured interviews and photographs of artists and clients.  By participating in tattooing, these individuals influence the art and the aesthetic tastes of their local culture.  Additionally, tattoo artists follow an ethical code that dictates how to run their business, preserve their art, and protect their clients.  By choosing Flax Roots Tattoo Studio as my fieldwork site, I was able to answer the questions: 1. How do tattoo artists and their clients engage with and shape tattoo art and its aesthetic at Flax Roots Tattoo Studio? ; and 2. How do these tattoo artists’ ethics influence their relationships with their clients and art?
