Governance and community capitals : understanding how governance has worked in three faith-based schools in the Western Highlands of Papua New Guinea

This thesis, titled Governance and Community Capitals, explores the kinds of practical processes that have made governance work in three faith-based schools in the Western Highlands of Papua New Guinea (PNG). To date, the nation of PNG has been unable to meet its stated educational goals; however, some faith-based primary schools have overcome educational challenges by changing their local governance systems. What constitutes good governance in developing countries and how it can be achieved in a PNG schooling context has received very little scholarly attention. In this study, the subject of governance is approached at the nexus between the administrative sciences and asset-based community development. In this space, the researcher provides an understanding of the contribution that community capitals have made to understandings of local forms of governance in the development context. However, by and large, conceptions of governance have a history of being positioned within a Euro-centric frame and very little, if anything is known about the naming of capitals by indigenous peoples. In this thesis, six indigenous community capitals are made visible, expanding the repertoire of extant capitals published to date. The capitals identified and named in this thesis are: Story, Wisdom, Action, Blessing, Name and Unity. In-depth insights into these capitals are provided and through the theoretical idea of performativity, the researcher advances an understanding of how the habitual enactment of the practical components of the capitals made governance work in this unique setting. The study draws from a grounded and appreciative methodology and is based on a case study design incorporating a three-stage cycle of investigation. The first stage tested the application of an assets-based method to documentary sources of data including most significant change stories, community mapping and visual diaries. In the second stage, a group process method relevant to a PNG context was developed and employed. The third stage involved building theory from case study evidence using content analysis, language and metaphorical speech acts as guides for complex analysis. The thesis demonstrates the contribution that indigenous community capitals can make to understanding local forms of governance and how PNG faith-based schools meet their local governance challenges.

The effects of acute administration of Chinese aphrodisiacs sold in Blantyre City on sperm characteristics and fertility profile in guinea pigs

Background Chinese aphrodisiacs have become popular remedy for sexual dysfunction and improvement of libido in men in Malawi. However, selling of these drugs seems not to be well regulated. Probably the aphrodisiacs that are currently on the market have unknown efficacy, potency and safety profiles. The aim of this study was to assess the efficacy of imported Chinese aphrodisiacs using guinea pigs as a model. Materials and Methods Two types of drugs were purchased from vendors in Blantyre City. Tonic tea, which was purported to improve erectile function and libido, and sperm multiplier tablets which were claimed to increase the sperm count. The tonic tea was prepared by soaking one tea bag in 100ml boiling water. The tea was cooled and administered to eight male experimental animals in varying doses. Each animal was introduced into a separate cage with a female guinea pig. Sexual behaviour such as mounting, sniffing behind the female were observed and recorded. Each sperm multiplier tablet was dissolved in distilled water and administered to the experimental animals in the morning and evening for seven days. At the end of the treatment, the experimental and control animals were sacrificed, their semen collected and analysed sperm motility, concentration and morphology. Results For the tonic tea, there were no statistical differences between the experimental and the control animals in terms of the number of mountings and sniffing behind the female. The sperm multiplier drug showed statistically significant differences between the experimental and the control animals in terms of the sperm motility (78.24 ± 1.35 vs. 86.54 ± 1.88, p< 0.05), and concentration (54.28 ± 1.24 vs. 67.59 ± 2.12, p<0.05). Conclusion The tonic tea did not show any efficacy in improving erection and libido. The sperm multiplier tablets, purported to increase sperm production, significantly increased the sperm motility, sperm concentration in the treated animals.

Filhos da independência: etnografando os estudantes Bissau-guineenses do PEC-G em Fortaleza-CE e Natal-RN

Notre travail propose de comprendre l`immigration africaine contemporaine du Brésil à travers l'univers des étudiants guinéens participant au Programme Étudiants « Convênio de Graduação » (PEC-G) dans les villes de Fortaleza dans l'Etat Ceará et Natal dans l'Etat de Rio Grande do Norte, en étudiant leurs stratégies de convivialité et d'adaptation. Les étudiants étrangers sélectionnés dans ce programme font leur licence gratuitement dans les Instituts d'Enseignement Supérieur (IES). Pour accéder à ce programme ils doivent répondre à certains critères : montrer qu'ils sont en mesure de payer leurs frais au Brésil, avoir le bac ou un diplôme équivalent et maîtriser la langue portugaise lorsqu'ils sont originaires d'un pays n'appartenant pas à la Communauté de Pays de Langue Portugaise (CPLP). Les étudiants qui participent à des programmes de développement socio-économique contractés entre le Brésil et leurs pays d'origine sont prioritaires. Ces accords les contraignent à rentrer dans leurs pays d'origine et de travailler dans le domaine dans lequel ils ont été diplômés une fois les études terminées. Les étudiants, qui arrivent au Brésil porteurs de leurs identités ethniques guinéennes, entrent en contact avec la société brésilienne et acquièrent ainsi une « identité hybride ». C'est dans ce contexte que ce travail analyse le quotidien des étudiants africaines au Brésil avec un regard porté sur les étudiants de Guinée-Bissau à Fortaleza et à Natal comprendre l'expérience des étudiants qui vivent en terre étrangère. Ainsi, le lieu (Brésil) prend toute sa valeur par rapport au distant (Guinée) autrefois lié par l'histoire coloniale et aujourd'hui lié par des relations internationales ou diplomatiques. Finalement, la construction d'une « nouvelle » identité ethnique, d'une culture guinéenne au Brésil s'opère dans une célébration mobile c'est-à-dire successivement formée et transformée en relation avec les formes à travers lesquelles l'individu est représenté ou interpelé dans les systèmes culturels dans lesquels il est impliqué.

Political life writing in Papua New Guinea: what, who, why?

This book aims to reflect on the experiential side of writing political lives in the Pacific region. The collection touches on aspects of the life writing art that are particularly pertinent to political figures: public perception and ideology; identifying important political successes and policy initiatives; grappling with issues like corruption and age-old political science questions about leadership and ‘dirty hands’. These are general themes but they take on a particular significance in the Pacific context and so the contributions explore these themes in relation to patterns of colonisation and the memory of independence; issues elliptically captured by terms like ‘culture’ and ‘tradition’; the nature of ‘self’ presented in Pacific life writing; and the tendency for many of these texts to be written by ‘outsiders’, or at least the increasingly contested nature of what that term means.

Mobility and emplacement in north coast Papua New Guinea: worlding the Pacific marine industrial zone

On the north coast of Papua New Guinea, the construction of the Pacific Marine Industrial Zone is catalysing movements of people, capital and things, as well as of the ideas and imaginings which accompany and make them meaningful. Drawn from literary and postcolonial studies, the concept of worlding offers a narrative framework through which to think through these movements and the ways in which they complicate prevailing narratives of globalisation. At the Pacific Marine Industrial Zone, the neoliberal worldings that inform the project do not simply catalyse movements, but also act to impose barriers to movement. Local communities assert connection to place, but also generate new circuits of mobility, and rearticulate ideas of kastom (custom) that have movement at their core. An emphasis on worlding-drawing particularly on Heidegger's distinction between world and earth-allows for a more complex reflection on the relationship between mobility and emplacement, one that more fully illuminates the complexity of the relationship itself, and the way it is experienced at the PMIZ site.

Efficacy of a parainfluenza virus 5 (PIV5)-based H7N9 vaccine in mice and guinea pigs: antibody titer towards HA was not a good indicator for protection.

H7N9 has caused fatal infections in humans. A safe and effective vaccine is the best way to prevent large-scale outbreaks in the human population. Parainfluenza virus 5 (PIV5), an avirulent paramyxovirus, is a promising vaccine vector. In this work, we generated a recombinant PIV5 expressing the HA gene of H7N9 (PIV5-H7) and tested its efficacy against infection with influenza virus A/Anhui/1/2013 (H7N9) in mice and guinea pigs. PIV5-H7 protected the mice against lethal H7N9 challenge. Interestingly, the protection did not require antibody since PIV5-H7 protected JhD mice that do not produce antibody against lethal H7N9 challenge. Furthermore, transfer of anti-H7 serum did not protect mice against H7N9 challenge. PIV5-H7 generated high HAI titers in guinea pigs, however it did not protect against H7N9 infection or transmission. Intriguingly, immunization of guinea pigs with PIV5-H7 and PIV5 expressing NP of influenza A virus H5N1 (PIV5-NP) conferred protection against H7N9 infection and transmission. Thus, we have obtained a H7N9 vaccine that protected both mice and guinea pigs against lethal H7N9 challenge and infection respectively.

Human rights in Papua New Guinea: is this where we should be settling refugees?

Australia has had a long, and at times tumultuous, relationship with our nearest neighbour, Papua New Guinea. This relationship took a twist in late 2012, with the re-opening of the off-shore processing centre on Manus Island, and again in February 2014, when Iranian asylum seeker Reza Berati was murdered by locals during a violent disturbance at the centre. The latest test of the strength and endurance of the relationship between PNG and Australia came in April 2016, when the PNG Supreme Court ruled that the detention of asylum seekers on Manus Island breached the right to personal liberty in the PNG constitution. This article provides much-needed insight into the human rights situation in PNG, and makes recommendations regarding the prospect of resettling refugees in that country.

Spreading the word: using film to share research findings and knowledge about children with disabilities in Vanuatu and Papua New Guinea

While there is increasing international interest in disability inclusive development, people with disability largely remain ‘unseen, unheard and uncounted’ (UN ESCAP 2012:1). Children with disability, particularly, remain excluded from research informing development, and there is a paucity of information that is drawn directly from the self-report of children with disability living in developing countries. This exclusion occurs across all stages of research, including access to research findings. When child research is conducted in such countries, to gain further evidence to support disability inclusive development and advance human rights, researchers must question how findings will be reported back to participants and their communities, and seek a method that is both accessible and culturally relevant. This paper reports on the Voices of Pacific children with disability research project about the human rights of children with disability in Vanuatu and Papua New Guinea (PNG), and focuses on film as a dissemination method. Project researchers developed methods to enhance the participation of children with diverse disabilities as informants, and drew upon community development principles to disseminate research findings via film; a method that resonated with the aural and visual story telling traditions of participants.This medium also included accessibility features that have been utilised by local and international audiences.

Land use change from rainforests to oil palm plantations and food gardens in Papua New Guinea: Effects on soil properties and S fractions

Changes in soil sulfur (S) fractions were assessed in oil palm and food garden land use systems developed on forest vegetation in humid tropical areas of Popondetta in northern Province. The study tested a hypothesis that S in food gardens are limiting nutrient factor and are significantly lower than in plantations and forests. Subsistence food gardens are under long-term slash and burn practice of cropping and such practice is expected to accelerate loss of biomass S from the ecosystem. From each land use, surface soil (0–15 cm) samples were characterised and further pseudocomplete fractionated for S. Conversion of forest to oil palm production decreased (p<0.001) soil pH and electrical conductivity values. The reserve S fraction in soil increased significantly (p<0.05) due to oil palm production ( 28 %) and food gardening activity (∼ 54 %). However, plant available SO42--S was below 15 mg kg^(−1) in the food garden soils and foliar samples of sweet potato crop indicating deficiency of plant available S. Soil organic carbon content (OC) was positively and significantly correlated to total S content (r=0.533; p<0.001) among the land use systems. Thus, crop management practices that affect OC status of the soils would potentially affect the S availability in soils. The possible changes in the chemical nature of mineralisable organic S compounds leading to enhanced mineralisation and leaching losses could be the reasons for the deficiency of S in the food garden soils. The results of this study conclude that long-term subsistence food gardening activity enriched top soils with reserve S or total S content at the expense of soluble S fraction. The subsistence cropping practices such as biomass burning in food gardens and reduced fallow periods are apparently threatening food security of oil palm households. Improved soil OC management strategies such as avoiding burning of fallow vegetation, improved fallows, mulching with fallow biomass, use of manures and S containing fertilisers must be promoted to sustain food security in smallholder oil palm system.

Chlamydial infection and spatial ascension of the female genital tract : a novel hybrid cellular automata and continuum mathematical model

Sexually transmitted chlamydial infection initially establishes in the endocervix in females, but if the infection ascends the genital tract, significant disease, including infertility, can result. Many of the mechanisms associated with chlamydial infection kinetics and disease ascension are unknown. We attempt to elucidate some of these processes by developing a novel mathematical model, using a cellular automata–partial differential equation model. We matched our model outputs to experimental data of chlamydial infection of the guinea-pig cervix and carried out sensitivity analyses to determine the relative influence of model parameters. We found that the rate of recruitment and action of innate immune cells to clear extracellular chlamydial particles and the rate of passive movement of chlamydial particles are the dominant factors in determining the early course of infection, magnitude of the peak chlamydial time course and the time of the peak. The rate of passive movement was found to be the most important factor in determining whether infection would ascend to the upper genital tract. This study highlights the importance of early innate immunity in the control of chlamydial infection and the significance of motility-diffusive properties and the adaptive immune response in the magnitude of infection and in its ascension.

Phylogenetic placement of the sugarcane orange rust pathogen Puccinia kuehnii in a historical and regional context

Sugarcane orange rust, caused by Puccinia kuehnii, was once considered a minor disease in the Australian sugar industry. However, in 2000 a new race of the pathogen devastated the high-performing sugarcane cultivar Q124, and caused the industry Aus$150–210 million in yield losses. At the time of the epidemic, very little was known about the genetic and pathogenic diversity of the fungus in Australia and neighbouring sugar industries. DNA sequence data from three rDNA regions were used to determine the genetic relationships between isolates within two P. kuehnii collections. The first collection comprised only recent Australian field isolates and limited sequence variation was detected within this population. In the second study, Australian isolates were compared with isolates from Papua New Guinea, Indonesia, China and historical herbarium collections. Greater sequence variation was detected in this collection and phylogenetic analyses grouped the isolates into three clades. All isolates from commercial cane fields clustered together including the recent Australianfield isolates and the Australian historical isolate from 1898.The other two clades included rust isolates from wild and garden canes in Indonesia and PNG. These rusts appeared morphologically similar to P. kuehnii and could potentially pose a quarantine threat to the Australian sugar industry. The results have revealed greater diversity in sugarcane rusts than previously thought.

The world of science education : handbook of research in Australasia

The focus of this Handbook is on Australasia (a region loosely recognized as that which includes Australia and New Zealand plus nearby Pacific nations such as Papua New Guinea, Solomon Islands, Fiji, Tonga, Vanuatu, and the Samoan islands) science education and the scholarship that most closely supports this program. The reviews of the research situate what has been accomplished within a given field in Australasian rather than international context. The purpose therefore is to articulate and exhibit regional networks and trends that produced specific forms of science education. The thrust lies in identifying the roots of research programs and sketching trajectories—focusing the changing façade of problems and solutions within regional contexts. The approach allows readers review what has been done and accomplished, what is missing, and what might be done next.

Host searching behaviour of Diachasmimorpha kraussii (Fullaway) (Hymenoptera: Braconidae: Opiinae), a polyphagous parasitoid of Dacinae fruit flies (Diptera: Tephritidae)

Diachasmimorpha kraussii (Hymenoptera: Braconidae: Opiinae) is a koinobiont larval parasitoid of dacine fruit flies of the genus Bactrocera (Diptera: Tephritidae) in its native range (Australia, Papua New Guinea, Solomon Islands). The wasp is a potentially important control agent for pest fruit flies, having been considered for both classical and inundative biological control releases. I investigated the host searching, selection and utilisation mechanisms of the wasp against native host flies within its native range (Australia). Such studies are rare in opiine research where the majority of studies, because of the applied nature of the research, have been carried out using host flies and environments which are novel to the wasps. Diachasmimorpha kraussii oviposited equally into maggots of four fruit fly species, all of which coexist with the wasp in its native range (Australia), when tested in a choice trial using a uniform artificial diet media. While eggs laid into Bactrocera tryoni and B. jarvisi developed successfully through to adult wasps, eggs laid into B. cucumis and B. cacuminata were encapsulated. These results suggest that direct larval cues are not an important element in host selection by D. kraussii. Further exploring how D. kraussii locates suitable host larvae, I investigated the role of plant cues in host searching and selection. This was examined in a laboratory choice trial using uninfested fruit or fruit infested with either B. tryoni or B. jarvisi maggots. The results showed a consistent preference ranking among infested fruits by the wasp, with guava and peach most preferred, but with no response to uninfested fruits. Thus, it appears the wasp uses chemical cues emitted in response to fruit fly larval infestation for host location, but does not use cues from uninfested fruits. To further tease apart the role of (i) suitable and non-suitable maggots, (ii) infested and uninfested fruits of different plant species, and (iii) adult flies, in wasp host location and selection, I carried out a series of behavioural tests where I manipulated these attributes in a field cage. These trials confirmed that D. kraussii did not respond to cues in uninfested fruits, that there were consistent preferences by the wasps for different maggot infested fruits, that fruit preference did not vary depending on whether the maggots were physiologically suitable or not suitable for wasp offspring development, and finally, that adult flies appear to play a secondary role as indicators of larval infestation. To investigate wasp behaviour in an unrestrained environment, I concurrently observed diurnal foraging behaviours of both the wasp and one of its host fly in a small nectarine orchard. Wasp behaviour, both spatially and temporally, was not correlated with adult fruit fly behaviour or abundance. This study reinforced the point that infested fruit seems to be the primary cue used by foraging wasps. Wasp and fly feeding and mating was not observed in the orchard, implying these activities are occurring elsewhere. It is highly unlikely that these behaviours were happening within the orchard during the night as both insects are diurnal. As the final component of investigating host location, I carried out a habitat preference study for the wasp at the landscape scale. Using infested sentinel fruits, I tested the parasitism rate of B. tryoni in eucalyptus sclerophyll forest, rainforest and suburbia in South East Queensland. Although, rainforest is the likely endemic habitat of both B. tryoni and D. kraussii, B. tryoni abundance is significantly greater in suburban environments followed by eucalyptus sclerophyll forest. Parasitism rate was found to be higher in suburbia than in the eucalyptus sclerophyll forest, while no parasitism was recorded in the rainforest. This result suggests that wasps orient within the landscape towards areas of high host density and are not restricted by habitat types. Results from the different experiments suggest that host searching, selection and utilisation behaviour of D. kraussii are strongly influenced by cues associated with fruit fly larval feeding. Cues from uninfested fruits, the host larvae themselves, and the adult host flies play minimal roles. The discussion focuses on the fit of D. kraussii to Vinson’s classical parasitoid host location model and the implications of results for biological control, including recommendations for host and plant preference screening protocols and release regimes.

Taxonomy and diagnostics of fruit fly infesting Opiine Braconids in Australia and the South Pacific

Opiine wasps (Hymenoptera: Braconidae: Opiinae) are parasitoids of dacine fruit flies (Diptera: Tephritidae: Dacinae), the primary horticultural pests of Australia and the South Pacific. Effective use of opiines for biological control of fruit flies is limited by poor taxonomy and identification difficulties. To overcome these problems, this thesis had two aims: (i) to carry out traditional taxonomic research on the fruit fly infesting opine braconids of Australia and the South Pacific; and (ii) to transfer the results of the taxonomic research into user friendly diagnostic tools. Curated wasp material was borrowed from all major Australian museum collections holding specimens. This was supplemented by a large body of material gathered as part of a major fruit fly project in Papua New Guinea: nearly 4000 specimens were examined and identified. Each wasp species was illustrated using traditional scientific drawings, full colour photomicroscopy and scanning electron microscopy. An electronic identification key was developed using Lucid software and diagnostic images were loaded on the web-based Pest and Diseases Image Library (PaDIL). A taxonomic synopsis and distribution and host records for each of the 15 species of dacine-parasitising opiine braconids found in the South Pacific is presented. Biosteres illusorius Fischer (1971) was formally transferred to the genus Fopius and a new species, Fopius ferrari Carmichael and Wharton (2005), was described. Other species dealt with were Diachasmimorpha hageni (Fullaway, 1952), D. kraussii (Fullaway, 1951), D. longicaudata (Ashmead, 1905), D. tryoni (Cameron, 1911), Fopius arisanus (Sonan, 1932), F. deeralensis (Fullaway, 1950), F. schlingeri Wharton (1999), Opius froggatti Fullaway (195), Psyttalia fijiensis (Fullaway, 1936), P. muesebecki (Fischer, 1963), P. novaguineensis (Szépliget, 1900i) and Utetes perkinsi (Fullaway, 1950). This taxonomic component of the thesis has been formally published in the scientific literature. An interactive diagnostics package (“OpiineID”) was developed, the centre of which is a Lucid based multi-access key. Because the diagnostics package is computer based, without the space limitations of the journal publication, there is no pictorial limit in OpiineID and so it is comprehensively illustrated with SEM photographs, full colour photographs, line drawings and fully rendered illustrations. The identification key is only one small component of OpiineID and the key is supported by fact sheets with morphological descriptions, host associations, geographical information and images. Each species contained within the OpiineID package has also been uploaded onto the PaDIL website (www.padil.gov.au). Because the identification of fruit fly parasitoids is largely of concern to fruit fly workers, rather than braconid specialists, this thesis deals directly with an area of growing importance to many areas of pure and applied biology; the nexus between taxonomy and diagnostics. The Discussion chapter focuses on this area, particularly the opportunities offered by new communication and information tools as new ways delivering the outputs of taxonomic science.
