title: Ecology and conservation of Alseuosmia quercifolia (Alseuosmiaceae) in the Waikato region, New Zealand

authors: Merrett, M. F.

subjects: Alseuosmia

abstract: The ecology of Alseuosmia quercifolia, a small endemic shrub, was investigated, focussing on its habitat requirements, population dynamics, phenology and reproductive biology, and conservation status. This species occurs most commonly in lowland native forests of the Waikato region of the North Island (north of latitude 38°05'S), but is also found in scattered populations to North Cape. In the Waikato region it typically occupies shady, well-drained, south or south-east facing lower slopes of hills and ranges at altitudes below 400 m. Population structures show considerable variation amongst seven study sites in the Waikato region, with disjunct size classes a reflection of the presence and abundance of introduced browsing mammals. It is a relatively short-lived (less than 50 years), slow-growing species with a fleshy fruit adapted to bird dispersal, but seed dispersal now appears to be primarily by gravity. Flowering occurs early in spring and is synchronous at both individual and population levels, occurring over a 5-week period, with peak flowering during the second and third weeks. While all populations set seed, reproductive output can be negatively affected by persistent browse and by rain during peak flowering. This species is vulnerable because it is highly palatable to introduced mammals and all plants in a population are within browse height. It has relatively narrow habitat specificity, localised distribution, and limited potential to extend its range. We suggest it fulfils the requirements of the category "declining", using the most recent classification of threatened and uncommon plants of New Zealand.

title: Export participation, employee benefits, and firm performance: The evidence from Vietnam’s manufacturing SMEs

authors: Vu, Van Huong

abstract: Vietnam has seen a significant rise in the number of SMEs since introducing the Enterprise Law in 2000. Non-state SMEs are playing a key role in economic growth, creating jobs, and reducing poverty. However, these non-state SMEs   participate only modestly in export activity despite the high export performance of the economy. What are the factors impeding export participation? And how does the role of export performance affect employee benefits (e.g. higher wages) and firm performance? This thesis is the first study to provide empirical evidence for answering these research questions.

Chapter 3 investigates the causal relationship between export participation and productivity by examining two popular hypotheses, self-selection and learning by exporting. Using a balanced panel dataset from 2005-2009 for Vietnamese private manufacturing SMEs, the results show strong statistical evidence for the self-selection of more productive firms into the export market. The alternative hypothesis, learning by exporting, is shown to be invalid by employing a fixed-effect panel data estimation and a fixed-effect instrumental variable regression. This study also reveals that export participation has no impact on technical efficiency, technical progress, and scale change.  

Chapter 4 explores the role of export participation in increasing employee benefits in terms of wages and employment quality.  First, based on a unique, matched firm-worker panel dataset between 2007 and 2009, the study shows that export participation has a positive impact on wages when taking into account only firm characteristics. However, the exporter wage premium falls and dissipates when both firm and worker characteristics are controlled for. In addition, the    effect decreases further and becomes less significant when controlling for time-invariant, unobservable factors by a spell fixed-effect estimation.   Second, using a firm level balanced panel dataset in the same period, the results show that there is a positive linkage between export participation and the share of casual workers. However, the effect of export participation on wages and employment quality varies greatly across sectors. 

Chapter 5 investigates linkages between export participation, firm survival and profitability in Vietnam. Using an unbalanced panel dataset from 2005 to 2009, the study shows no difference in survival probability between exporters and non-exporters. However, the probability of a firm’s survival is greater for those who engage continuously in export but is lower for firms which have ceased export activity, as indicated by their export status at different stages. Using ordinary least squares (OLS) to consider the relationship between firm profitability and export activity, the results indicate that export status is not related to firm profit growth. However, a quantile regression approach shows that export participation is positively related to profitability for firms with high profit growth but negatively related for those firms with low profit growth. This might suggest that the productivity advantages of exporters with low profit growth are absorbed by costs relating to trading activities in overseas markets.

This thesis may have several potential policy implications. First, export promotion policies may not be effective if they are not accompanied by strategies to help SMEs become more productive. In addition, policies encouraging and supporting exports should focus not only on the number of employment created but also on the quality of employment, especially for low-technology industries. Finally, export-promoting policies (e.g. improvement in firms’ innovative activities) coupled with policies maintaining firms’ positions in export markets could be helpful since these measures in turn may help firms improve their survival probability and profit growth. However, the policy issues are very complicated and these suggestions should therefore be considered an initial foundation for further study.

title: The Wairua of Self: A Path of Love, Simplicity, and Connectedness

authors: Frishman, Lezlie

subjects: love

abstract: Love is an action of freedom until something else steps in – often fear – that insists we create a box of survival. Whether self-imposed, forced, or chosen, it is interesting to notice how we limit ourselves with love. This thesis examines love; love in its purest intent and creation as the simplest way to live. An analysis of personal experiences, illuminated by psychological, mythological, philosophical, and spiritual literature, suggests that living from a place of love can be accomplished through a dedicated journeying back to the Self. The Māori myth of Tāne-Mahuta and Hine-Tītama shows the significance of releasing shame, as well as how a tragic situation might offer a catalytic possibility that shifts a core belief about one’s self. The complications of love that are self-created through loss and grief can easily mask the barely underlying truth of love in its nakedness. Reconnecting with this underlying truth, aroha in its purest sense, is essential for healing and allows for increased connection with the Divine. Doing so is often a difficult task, as hypocrisies fueled by fear and perpetuated by blame are bountiful. When love is used as an instrument and convenience in order to defend a closely held idea, person, or way of life, one often moves further from their true Self, thus surrendering their deepest power and knowing of love. The silent assault of expectations, power, will, and control can turn love into a complication. The complications of being utterly human only serve to further obscure love. Within families, how one initially learns love is often complicated by interrupted attachment, causing rebellion and the need to look for love elsewhere. The components of Tikkun Olam, aroha, mikveh, and wairua of spirit, are intertwined and interconnected, such that the delineation between cultures and spiritual beliefs cannot be divided as oppositional forces. The denominator lives in the magnitude of love for all that has been created; beginning with the Self. In setting the foundation of self-love and allowing it to settle into the fractures and rifts of porousness, love may then be extended without attachment. When freely proffered without agenda, love will seep into every curve of the universe; thus, changing the world. Through the practice of mindfulness and loving-kindness, perception can change. It is this change in perception which can return love to its origin of simplicity. This thesis is a story of love.
