Air pollution measurements are aimed at improving our understanding of the chemical properties of the atmosphere, addressing mainly three issues with very different space and time scales: • Measurement of critical or peak values of air pollutant in densely urbanized/industrialized sites. • Long term observation and trend analysis on air quality. • Evaluation of photochemical pollution (smog) ep...

Modern scientific endeavour is increasingly delivered within an interdisciplinary framework. Analytical environmental chemistry is a long-standing example of an interdisciplinary approach to scientific research where value is added by the close cooperation of different disciplines. This editorial piece discusses the rise of environmental analytical chemistry as an interdisciplinary activity and...

When the effect is studied of a factor like 'orthodontic therapy' on linear craniofacial growth, the concomitant consequence of age and gender on size cannot be ignored. The methodologically correct solution is division of the study group into smaller units, each of which is homogeneous with respect to age, gender, and therapy, and to compare these with matched controls. Yet, apart from matched...

Sharpening the Effectiveness of Natural Experiments as an Analytical Tool The importance of using natural experiments in economic research has long been recognized. Yet, it is only in recent years that natural experiments have become an integral part of the economist’s analytical toolbox, thanks to the efforts of Meyer, Card, Peters, Krueger, Gruber, and others. This use promises to shed new li...

There are various methods for understanding user experiences, but many of these focus on explicit and not implicit aspects. Teasing Apart, Piecing Together (TAPT) is a method that was developed to understand and redesign experiences, crossing web / non-web boundaries [9]. This paper presents a case study of its repurposing towards understanding online experiences more deeply, in this case consi...

Morphology plays an essential role in chemistry through the segregation of atoms and/or molecules into different phases, delineated by interfaces. This is a general process in materials synthesis and exploited in many fields including colloid chemistry, heterogeneous catalysis, and functional molecular systems. To rationally design complex materials, we must understand and control morphology ev...

Immunoassays for biotechnology engineered proteins are used by AgBiotech companies at numerous points in product development and by feed and food suppliers for compliance and contractual purposes. Although AgBiotech companies use the technology during product development and seed production, other stakeholders from the food and feed supply chains, such as commodity, food, and feed companies, as...

While China is recognized as an important software outsourcing outlet today, its growth as a software outsourcing outlet is not without struggle. This article examines the early-day growth of China as a software outsourcing outlet, discusses hindering factors that once constrained China’s potential as a software outsourcing service provider, and identifies various enabling factors that contribu...
