title: Ozone Depletion and Global Warming

authors: Fow, Alista John

subjects: Ozone Depletion

abstract: Abstract
This thesis examines global warming and the possible contribution that ozone
depletion provides to this warming. An examination is performed to determine
the extent of any warming/cooling events within the Earth-atmosphere
system. The change in energy corresponding to this warning of the Earth-
atmosphere system is estimated as being equivilent to an increase of mean
solar input of 0.22W/m2. This is compared to the predicted changes of solar
input for the two most common global warming scenarios: greenhouse gases
and solar irradiance variance; and for a less well explored scenario, snow-ice
albedo change. Examination of ozone depletion data shows that an absence of
ozone in the stratosphere produces an increase in UV-B radiation at the surface
of the Earth. This increase in UV-B light has not previously been thourougly
examined in any of the global warming scenarios. This is presented as a fourth
scenario for global warming.
An analytical three layer model of the Earth-atmosphere, based on an earlier
two layer model, is developed. Using this model it is determined that
greenhouse gases, solar irradiance, snow-ice albedo feedback and ozone depletion
can cause warming of the Earth's atmosphere. After comparison with
other models, a snow-ice albedo mechanism is incorporated into the three layer
model. This produces an amplification effect of any warming that occurs.
Compared to the observed increase of surface temperature between 1975-2000
of 0.55 K, the model using a snow-ice albedo feedback, produced an increase
of temperature of 1.4 K for greenhouse gases, 0.294 K for a solar irradiance increase
and 0.119 K caused by a decrease in the ozone layer. Of the greenhouse
gas, solar irradiance and ozone depletion scenarios, ozone depletion demonstrates
the most realistic relative changes with a cooling of the stratosphere
and a warming of the troposphere and Earth's surface as has been observed.
It is concluded that ozone depletion is likely for a reasonable part of observed
global warming.

title: Understanding the construction of marketers’ credibility by NZ senior managers: An interpretive study

authors: Harrison, Lee John

subjects: Marketer

abstract: Academics report that marketers are losing their influence in the boardroom due in part to serious challenges to marketing’s credibility. Although the credibility of marketing sources has received much attention since the early 1950s, research into how individuals in business organisations construct the credibility of marketers is scarce. This study, using in-depth interviews, describes how seven senior managers from different New Zealand businesses construct the credibility of marketers. For these senior managers, the credibility of marketers is grounded in their performance in delivering commercial outcomes. The findings also suggest that senior managers construct credibility in terms of a work aspect and a social aspect of a marketer’s performance, and that both these aspects have to be present if the marketer is to be considered credible.
 
The work aspect of performance is made up of a marketer’s Pedigree, Projects, and Pervasive Influence. The Pedigree of a marketer includes their qualifications, skills and background. A degree is usually the minimum qualification required, particularly for more senior marketing roles. Skills expected from marketers include leadership, management, sales and intuition. With regard to background, the marketer needs to demonstrate they have achieved commercial outcomes in previous employment to be considered credible. 

Projects describes how marketers must design and implement cogent marketing plans, work effectively without supervision, achieve commercial outcomes in a clever or creative way, and provide evidence that their projects have contributed to commercial outcomes. Pervasive Influence describes how marketers influence others in the organisation toward customer-centricity. Marketers can lose credibility in the work aspect of their performance when they have no structured purpose to their marketing research, are unable to execute marketing plans or are unable to demonstrate the results of a marketing project.

The social aspect of a marketer’s performance is made up of Personal Integrity and Professional Conduct. Personal Integrity describes marketers who are respected, take pride in their work, strive to improve themselves and are not precious. Professional Conduct describes a marketer who relates and collaborates competently and professionally with others, and is a team fit. Marketers lose credibility in the social aspect of their performance when they are precious, flighty, argumentative, and only out for themselves. 

This paper contributes a framework that describes the construction of a marketer’s credibility from a senior manager’s perspective. It also introduces a new understanding of credibility, grounded in performance terms, which is distinct from past conceptualisations of credibility found in the literature, which is based on expertise and trustworthiness. These findings demonstrate that while a marketer might be considered an expert and trustworthy, if they are not delivering commercial outcomes then they may not be considered credible, from a senior manager’s perspective.

title: A walking stick in one hand and a chainsaw in the other: Patients’ perspectives of living with multimorbidity

authors: Signal, Louise

abstract: AIMS: Multimorbidity is common, yet there are major gaps in research, particularly among younger and indigenous populations. This research aimed to understand patients’ perspectives of living with multimorbidity. 

METHODS: A qualitative study of 61 people living with multimorbidity, 27 of whom were Māori and a third aged under 65, from urban and rural regions in New Zealand. Six focus groups and 14 interviews were conducted, recorded, transcribed and analysed. 
RESULTS: For many participants, living with multimorbidity disrupted their ‘normal’ lives, posing challenges in everyday activities such as eating and toileting, working and managing medications. Dealing with the health system posed challenges such as accessing appointments and having enough time in consultations. Cultural competency, good communication and continuity of care from healthcare providers were all valued. Participants had many recommendations to improve management, including a professional single point of contact to coordinate all specialist care. 
CONCLUSIONS: Living with multimorbidity is often challenging requiring people to manage their conditions while continuing to live their lives. This research suggests changes are needed in the health system in New Zealand and elsewhere to better manage multimorbidity thus improving patient’s lives and reducing costs to the health sector and wider society.
