title: Firm exporting and employee benefits: first evidence from Vietnam manufacturing SMEs

authors: Vu, Van Huong

subjects: exporting

abstract: This study examines linkages between the export participation of firms and employee benefits in terms of wages and employment quality. Based on a uniquely matched firmworker panel dataset for 2007 and 2009, we find evidence that export participation by firms in Vietnam has a positive impact on wages when taking into account firm characteristics alone. However, the exporter wage premium falls when both firm and worker characteristics are controlled for, and it decreases further when controlling for time-invariant unobservable factors by spell fixed effect estimation. While there are many studies on the export wage premium, the role of export participation on the quality of employment remains largely unexplored. By using a firm-level balanced panel dataset for the same period, our results suggest that export participation has a negative effect on employment quality. Nevertheless, the impact of export participation on both wages and employment quality vary greatly with respect to levels of technology.

title: Identification of the floral source of New Zealand honeys

authors: Petchell, Laura Eleanor

subjects: Honey

abstract: Depending on the nectar source, honey is either unifloral (derived mostly from one plant type), or polyfloral (derived from multiple plant types). Unifloral honey has characteristic sensory properties, and is therefore of greater commercial value. Currently, identification of floral source involves pollen counting, a specialised and labour intensive process. The current research was aimed at developing an alternative, rapid, chemistry-based method of floral identification. The aroma of honey depends on volatile compounds present; these may be derived from the plant from which nectar was taken. Therefore by identifying volatiles in honey it could be possible to identify floral source. Solid-phase microextraction (SPME) is a technique that is useful for the headspace analysis of volatile compounds; when coupled with GC-MS it provides a powerful tool for fingerprinting volatiles in honey. GC-MS chromatograms of ten New Zealand unifloral honey types were obtained after headspace SPME extraction. Statistical analysis of the GC-MS chromatographic data was used to discriminate between floral types. Probability plots were used to identify compounds indicative of floral source; this method discriminated between honey types with 90% success. Hierarchical cluster analysis and principal component analysis were used to study the structure of the data. Learning algorithms in Weka (machine-learning software) were used to build models of data to classify honey types. The logistic model tree algorithm classified 89.8% of samples correctly. Such a model has the potential to be used to classify future honey samples, once further samples have been tested to validate the model.

title: The Rangatahi court

authors: Dickson, Matiu

abstract: It has become popular to use the marae setting as an alternative to the mainstream courts in dealing with young Māori offenders. The rationale is that taking young Māori offenders back to the marae to be dealt with in the youth justice system, encourages them to face up to their responsibilities and aids their rehabilitation back into the community. The expectation is that whānau will be present to support the young person and to help resolve his or her offending and bad behaviour. I supported this innovation when it was introduced but now I have second thoughts having seen that a marae that piloted this scheme was vandalised with graffiti painted on the marae buildings. In my view, when this happened the scheme to use marae should have ceased and an opportunity taken to rethink their use in this way. For a Māori the vandalism of their marae is like a physical assault on the person of their tupuna. This paper looks at the traditional role of marae in the Māori community and questions the use of marae as judicial settings. It suggests what needs to be done first to make this setting tika or appropriate.
