Reform of the New Zealand Health System:problematization, mobilization and change

This paper will seek to explicate the changes in the New Zealand health sector informed by the concepts of problematization, inscription and the construction of networks (Callon, 1986; Latour, 1987, 1993). This will involve applying a framework of interpretation based on the concepts of Latour's sociology of translation. Material on problematization and inscription will be incorporated into the paper in order to provide an explanatory frame of reference which will enable us to make sense of the processes of change in the New Zealand health sector. The sociology of translation will be used to explain the processes which underlie the changes and will be used to capture effects, such as changes in policy and structure, producing new networks within which 'allies' could be enrolled in support of the health reforms.

Knowledge management in a New Zealand tree farming company:Ambiguity and resistance to the "technology solution"

Purpose - Managers at the company attempt to implement a knowledge management information system in an attempt to avoid loss of expertise while improving control and efficiency. The paper seeks to explore the implications of the technological solution to employees within the company. Design/methodology/approach - The paper reports qualitative research conducted in a single organization. Evidence is presented in the form of interview extracts. Findings - The case section of the paper presents the accounts of organizational participants. The accounts reveal the workers' reactions to the technology-based system and something of their strategies of resistance to the system. These accounts also provide glimpses of the identity construction engaged in by these knowledge workers. The setting for the research is in a knowledge-intensive primary industry. Research was conducted through observation and interviews. Research limitations/implications - The issues identified are explored in a single case-study setting. Future research could look at the relevance of the findings to other settings. Practical implications - The case evidence presented indicates some of the complexity of implementation of information systems in organizations. This could certainly be seen as more evidence of the uncertainty associated with organizational change and of the need for managers not to expect an easy adoption of intrusive IT solutions. Originality/value - This paper adds empirical insight to a largely conceptual literature. © Emerald Group Publishing Limited.

New technology, industrial relations and white collar trade unions : the case of the National and Local Government Officers Association

The decade since 1979 has seen the most rapid introduction of microelectronic technology in the workplace. In particular, the scope offered for the application of this new technology to the area of white collar work has meant that it is a sector where trade unions have been confronted with major challenges. However the application of this technology has also provided trade unions with opportunities for exerting influence to reshape traditional attitudes to both industrial relations and the nature of work. Recent academic research on the trade union response to the introduction of new technology at the workplace suggests that, despite the resources and apparent sophistication of modern trade unions, they have not in general been able to take advantage of the opportunities offered during this period of radical technological change,the argument being that this is due both to structural weaknesses and the inappropriateness of the system of collective bargaining where new technology issues are concerned. Despite the significance of the Public Sector in employment terms, research into the response of public sector white collar trade unions to technological change has been fairly limited. This thesis sets out the approach of the National and Local Government Officers Association (NALGO), the largest solely white collar union in the world with over three quarters of a million members employed in a wide range of public service industries. The thesis examines NALGO's response at national level and, through detailed case studies, at local level in respect of Local Government and Water Industry NALGO members. The response is then evaluated and conclusions drawn in terms of a framework based upon an assessment of the key factors relevant in judging the ability of NALGO to respond effectively to the challenges brought about by the technological revolution of the last ten years.

Pathway to clozapine use:a comparison between a patient cohort from New Zealand and a cohort from the United Kingdom

Background and Objective: Clozapine has been available since the early 1990s. Studies continue to demonstrate its superior efficacy in treatment-resistant schizophrenia. Despite this, numerous studies show under-utilisation, delayed access and reluctance by psychiatrists to prescribe clozapine. This retrospective cross-sectional study compared the prescribing of clozapine in two adult cohorts under the care of large public mental health services in Auckland (New Zealand) and Birmingham (United Kingdom) on 31 March 2007. Method: Time from first presentation to clozapine initiation, prior antipsychotics trialled and antipsychotic co-prescribing were compared. Data included demographics, psychiatric diagnosis, co-morbid conditions, year of first presentation, admissions and pharmacological treatment (clozapine dose, start date, prior antipsychotics, co-prescribed antipsychotic). Results: Overall, 664 people were prescribed clozapine (402 Auckland; 262 Birmingham); mean daily dose of 384 mg (Auckland) and 429 mg (Birmingham). 53 % presented after 1990 and the average duration of time before starting clozapine was significantly longer in the Birmingham cohort (6.5 vs. 5.3 years) but this reduced in both cohorts to a 1-year mean in those presenting within the last 3 years. The average number of antipsychotics trialled pre-clozapine for those presenting since 1990 was significantly higher in the Birmingham cohort (4.3 vs. 3.1) but in both cohorts this similarly reduced in those presenting within the last 3 years. Antipsychotic co-prescribing was significantly higher in the Birmingham cohort (22.9 vs. 10.7 %). Conclusions: There is evidence that access to clozapine has improved over time in both cohorts, with a reduction in the duration between presentation and initiation of clozapine and number of different antipsychotics trialled pre-clozapine. These are very positive findings in terms of optimising outcomes with clozapine and are possibly due to the impact of guideline recommendations, increasing clinician, consumer and carer knowledge, and experience with clozapine and funding changes. © 2014 Springer International Publishing.

Race Relations & Politics in Venezuela during Punto Fijo (1958 – 1998)

In 1998, Hugo Chávez Frías’ presidential candidacy brought race to national discussion in Venezuela for first time since 1945. For long, the country’s politics had abided by the myth of racial harmony and racial democracy. This approach pointed to institutional separation in the United States and Africa as examples of true racism. Latin America was largely void of such atrocities. Nonetheless, Chávez claimed the present political parties (Acción Democrática, Copei and Unión Republicana Democrática) disenfranchised the common, colored Venezuelan. He continued to assert the opposition’s racism during his presidency. And his political fanbase agrees. A variety of scholars have studied the break from Punto Fijo politics to the Bolivarian Revolution. Yet, few have linked the obvious class struggle to race. Here, I seek to explain how racial identity has shaped class identity in Venezuela by closely examining the Punto Fijo era (1958-1998). The essay begins with an overview of historical race relations, moving to the period in focus. Then, I examine systematic and institutional exclusion under Punto Fijo politics. The object is to understand the merit of Chávez’s racial claims since 1998. Hence, the study also sees democracy in action and the consequences of racial exclusion. The study will be accomplished through secondary research, considering the limitations brought by working abroad. In the end, this study serves as first step in analyzing the fall of what was once considered Latin America’s most durable democracy.

Lithofacies distribution in the western Bay of Plenty, New Zealand

Sediment dynamics on a storm-dominated shelf (western Bay of Plenty, New Zealand) were mapped and analyzed using the newly developed multi-sensor benthic profiler MARUM NERIDIS III. An area of 60 km × 7 km between 2 and 35 m water depth was surveyed with this bottom-towed sled equipped with a high-resolution camera for continuous close-up seafloor photography and a CTD with connected turbidity sensor. Here we introduce our approach of using this multi-parameter dataset combined with sidescan sonography and sedimentological analyses to create detailed lithofacies and bedform distribution maps and to derive regional sediment transport patterns. For the assessment of sediment distribution, photographs were classified and their spatial distribution mapped out according to associated acoustic backscatter from a sidescan sonar. This provisional map was used to choose target locations for surficial sediment sampling and subsequent laboratory analysis of grain size distribution and mineralogical composition. Finally, photographic, granulometric and mineralogical facies were combined into a unified lithofacies map and corresponding stratigraphic model. Eight distinct types of lithofacies with seawards increasing grain size were discriminated and interpreted as reworked relict deposits overlain by post-transgressional fluvial sediments. The dominant transport processes in different water depths were identified based on type and orientation of bedforms, as well as bottom water turbidity and lithofacies distribution. Observed bedforms include subaquatic dunes, coarse sand ribbons and sorted bedforms of varying dimensions, which were interpreted as being initially formed by erosion. Under fair weather conditions, sediment is transported from the northwest towards the southeast by littoral drift. During storm events, a current from the southeast to the northweast is induced which is transporting sediment along the shore in up to 35 m water depth. Shorewards oriented cross-shore transport is taking place in up to 60 m water depth and is likewise initiated by storm events. Our study demonstrates how benthic photographic profiling delivers comprehensive compositional, structural and environmental information, which compares well with results obtained by traditional probing methods, but offers much higher spatial resolution while covering larger areas. Multi-sensor benthic profiling enhances the interpretability of acoustic seafloor mapping techniques and is a rapid and economic approach to seabed and habitat mapping especially in muddy to sandy facies.

Distribution of planktonic foraminifera in Quaternary sediments east of New Zealand

A series of cores from east of New Zealand have been examined to determine the paleoceanographic history of the late Quaternary in the SW Pacific using planktonic foraminiferal data. Distinct shifts of species can be seen between glacial and interglacial times especially south of Chatham Rise east of South Island. Foraminiferal fragmentation ratios and benthic/planktonic foraminiferal ratios both show increased dissolution during glacials, especially isotope stage 2 to the south of Chatham Rise. The present-day Subtropical Convergence appears to be tied to the Chatham Rise at 44°S, but during glacial times this rise separated cold water to the south from much warmer water to the north, with an associated strong thermal gradient across the rise. We estimate that this gradient could have presented as much as an 8°C temperature change across 4°C of latitude during the maximum of the last ice age. There is only weak evidence of the Younger Dryas cool event, but there is a clear climatic optimum between 8 and 6.4 ka with temperatures 1°-2°C higher than the present day. The marine changes compare well with vegetational changes on both South and North Island.
