Full textAbstract:
Numerous pollinators are declining across the world. One of these, the swift parrot (Lathamus discolor) is a critically endangered Australian bird that feeds largely on the nectar and pollen of Eucalyptus trees. The Swift Parrot Recovery Plan includes competition for food from introduced social bees as a threatening process, although little evidence exists in support of this. Here, we present the strongest evidence yet to support this theory. We examined nectar standing crops in the species of trees that are important to swift parrots during their breeding season, Tasmanian blue gum (Eucalyptus globulus) and black gum (E. ovata). By comparing the amounts of nectar between flowers exposed to visitors and those bagged to exclude visitors throughout the day, we discovered that introduced honey bees (Apis mellifera) and bumble bees (Bombus terrestris) consumed most of the nectar and that exposed flowers often contained little nectar. Honey bees were the more common species, but bumble bees had greater per capita rates of nectar consumption. However, at low densities these bees had no effect on standing crops of nectar, and in such situations some nectar could be harvested by managed honey bees without reducing nectar availability for swift parrots. Although this study suggests that introduced social bees may pose a threat to swift parrots, further work is needed to determine whether our results are indicative of the impacts of bees across greater scales of time and space and whether these affect the reproductive success and conservation status of the swift parrot.

The critically endangered swift parrot (Lathamus discolor) is among the best studied Australian threatened species. Despite extensive outreach to the public and policy makers, conservation management has not kept pace with advances in knowledge and scientific evidence. Here we summarise policy and management failings that allow swift parrot breeding habitat in Tasmanian forests to continue to be logged. This practice continues in spite of extensive evidence demonstrating that the cessation of logging of swift parrot breeding habitat in Tasmania is urgently required to secure the species.

Full textAbstract:
The foraging ecology of the Swift Parrot Lathamus discolor in the box-ironbark forests and woodlands of Victoria was investigated over three years. We sought to identify features that characterized Swift Parrot foraging habitats. A total of 159 foraging sites was found, mainly in box-ironbark forests or nearby woodlands, and were located at a disproportionately high frequency on drainage lines, and a correspondingly low frequency on ridges. The species was observed foraging on 12 eucalypt and one Acacia species, but more than 90% of observations were of birds using Red Ironbark Eucalyptus tricarpa, Mugga Ironbark E. sideroxylon, Yellow Gum E. leucoxylon or Grey Box E. microcarpa. Nectar, lerp and other food from eucalypt foliage were frequent dietary items. Foraging and random sites were broadly similar in tree size-class structure. However, Swift Parrots selected trees in larger size classes for foraging more often than expected given the relative abundance of such trees. Larger trees flowered more reliably across the study area in all years. The habitat of the Swift Parrot in the study area is extensively fragmented and degraded, and management to increase the density of larger trees is recommended. We found considerable between-year variation in regional distribution and relative use of prinCipal tree species. The five identified regions within the study area all supported a significant percentage of the population in at least one of the three years. As a result, recovery measures will need to target important sites across the geographical extent of the study area.

Full textAbstract:
The endangered Swift Parrot Lathamus discolor breeds mostly in coastal south-eastern Tasmania, an area whereurban development is common and the city of Hobart is situated. Hobart’s suburbs are visited regularly by foragingSwift Parrots that nest in the surrounding forests. The reproductive success of Swift Parrots depends largely on theavailability of the birds’ major dietary items, the nectar and pollen of Eucalyptustrees. This study investigated therelative value of suburban trees and those in adjacent native forest in Hobart as food sources for Swift Parrots. Tothis end, we compared flower production between mature trees in suburban and bushland areas for the two specieson which Swift Parrots predominantly forage while breeding; Tasmanian Blue Gum Eucalyptus globulus and BlackGumE. ovata. For both species, flower production over the past few years was greater for individual trees in thesuburb than for those in the surrounding bushland. Hence, individual trees in the suburb probably provide more nectarand pollen than do those in the nearby bushland and are potentially important to the reproductive success of SwiftParrots. Our findings suggest that the relatively poor flowering in this peri-urban bushland may be the result of poorerhealth of trees in the bushland than in the suburb, particularly the greater fire damage and sparser canopies in thebushland trees. Further research is required to determine the frequency and intensity of fire in bushland that will promotethe greatest flower production in E. globulus andE. ovata.

Full textAbstract:
The Night Parrot Pezoporus occidentalis, known from just two specimens and with no confirmed sightings for just over 100 years, and having declined from being one of the most widespread of Australian birds, has surely been amongst the most enigmatic birds of the world and deservedly the ʻholy grailʼ for many birders. Amazingly, a population of this species has recently been re-discovered by John Young and the ʻquestʼ is over, but swift action is now required lest the ʻgrailʼ slip from our grasp. Steps must be taken to protect and manage the newly-located population, and to better understand the biology of the species and the reasons for its widespread decline. Much of this decline occurred before the end of the 19th century and must therefore have resulted from broad factors associated with earlier landscape changes, such as cat predation and altered fire regimes. Searches for additional Night Parrot populations also seem warranted. Progress toward these goals would benefit from acceptance of the reasonable accumulation of ʻunconfirmedʼ observations of the species and further utilizing the large numbers of ʻamateurʼ birders who would doubtless be keen to be involved. We suggest that the Night Parrot should now be viewed as an ʻiconʼ for conservation, possibly even an ʻindicatorʼ for how successful we are in terms of conservation in general. With his discovery of the Night Parrot, John Young has thus made a significant contribution to conservation, opening a new realm of necessities and possibilities.

AbstractWe analysed the supportive social networks associated with the conservation of six threatened Australian bird taxa, in one of the first network analyses of threatened species conservation programmes. Each example showed contrasting vulnerabilities. The Alligator Rivers yellow chat Epthianura crocea tunneyi had the smallest social network and no real action was supported. For the Capricorn yellow chat Epthianura crocea macgregori the network was centred on one knowledgeable and committed actor. The orange-bellied parrot Neophema chrysogaster had a strongly connected recovery team but gaps in the overall network could limit communication. The recovery teams for the swift parrot Lathamus discolor and Baudin's black-cockatoo Calyptorhynchus baudinii had strong links among most stakeholders but had weak ties to the timber industry and orchardists, respectively, limiting their capacity to manage threatening processes. Carnaby's black cockatoo Calyptorhynchus latirostris seemed to have the most effective social network of any of the taxa studied but may be vulnerable to skill shortages. In each case the network analysis pointed to gaps that could be filled to enhance the conservation effort, and highlighted the importance of recovery teams. The research suggests that formal network analysis could assist in the design of more effective support mechanisms for the conservation of threatened species.

Full textAbstract:
Conserving habitat for wide-ranging fauna species provides a challenge because impacts on these species tend to be dismissed based on the assumption that there is sufficient habitat in other areas of its range. This incremental loss of habitat is a serious conservation issue for a diversity of bird species. As knowledge of wide-ranging and migratory bird species increases, it often becomes evident that they select specific sites on a regular basis (i.e., the species exhibit site fidelity). Gaining a better understanding of site fidelity and selective habitat use for wide-ranging species is clearly important, but also extremely challenging. In this paper, challenges associated with conservation of the migratory and wide-ranging Swift Parrot Lathamus discolor are discussed as an example of how a recovery programme has aimed to address such conservation and management challenges. Despite the small population size (less than 2 500 birds), broad distribution (1 250 000 km2) and often cryptic nature, the implementation of the national recovery programme has been successful in the identification and protection of important habitats. This has been made possible by involving large numbers of volunteers who collect long-term sighting and habitat data over large areas, together with more detailed ecological research. This information is then used to inform the conservation assessment process and to improve habitat conservation throughout the range of the species.

Full textAbstract:
The swift parrot (Lathamus discolor, Psittacidae) is an endangered, austral migrant that inhabits forests and woodlands of south-eastern Australia. With a small population size (2500 birds), broad winter distribution (1 250 000 km2) and often cryptic nature, the swift parrot is a challenging species to study. In autumn they migrate north from their Tasmanian breeding grounds in search of suitable food resources throughout their winter range on mainland Australia. They are therefore dependent on a combination of suitable wintering, migration and breeding habitats. Although they spend a large proportion of their lives within winter habitats, the spatial and temporal dynamics of habitat use in this part of their range is poorly understood. This thesis aims to provide a greater understanding of large-scale winter habitat use by swift parrots, in both historic and current contexts, and provide a basis for future conservation management.
¶
Swift parrots, or red-shouldered paroquets as they were previously known, were among the first Australian birds to be scientifically described and illustrated following European settlement in 1788. However, within 60 years of settlement, habitats throughout the range of the species were being impacted upon. An important aspect of this habitat loss is the speed and spatial extent with which it occurred throughout the parrots broad distribution. Although the most extensive habitat loss in some areas occurred during colonial times, habitats continue to be lost as a result of various land management practices. Such impacts are also likely to be exacerbated by the ongoing cumulative impact with rapid climate change. As a result the swift parrot is an endangered species and is the subject of an ongoing national recovery program, to which this thesis contributes.
¶
Conserving habitat for the swift parrot, and other wide-ranging fauna species, is challenging since impacts in one area tend to be dismissed based on the assumption that there is sufficient habitat in other areas. These conservation challenges are discussed in regard to the national swift parrot recovery program. Although recovery program implementation for this species has been successful in identifying and protecting some important habitats, there are still many gaps in our knowledge that need to be addressed through a continuing and adaptive recovery effort, including an understanding of variable habitat use throughout their winter range.
¶
A study of swift parrot winter habitat use was therefore conducted at 53 sites across New South Wales over five years (2001-2005). Swift parrots used a diversity of winter foraging habitats in coastal and/or western slopes regions of New South Wales each year, including several habitats that occur in endangered ecological communities. Landscapes containing winter foraging habitat included scattered trees, remnant vegetation and continuous forests, and swift parrots foraged extensively on lerp and nectar from a diversity of tree species within these. The occurrence of swift parrots at foraging sites was primarily associated with the abundance of lerp, nectar and non-aggressive competitors. Although swift parrot abundance fluctuated significantly between years and regions, over half of all foraging sites were used repeatedly, highlighting their likely importance for conservation.
¶
Patterns of habitat use throughout the species winter range were also studied across five states/territories using volunteer data from 4140 surveys. These surveys were conducted by up to 300 volunteers twice a year, for seven years (1998-2004) with swift parrots detected in 19% of surveys. As a result, this study provided the first demonstration of large-scale drought related movements by a migratory population throughout their winter range. It also demonstrated the dynamic spatial and temporal patterns of winter habitat use, including repeated use of sites, by an austral migrant. Four regions in central Victoria were used most consistently, although the birds also visited other regions each year.
¶
During drought swift parrot abundance was significantly correlated with rainfall, whereby most of the population either concentrated in a few regions or migrated longer distances (up to 1000km) to drought refuges in wetter coastal areas. However, swift parrot abundance was not associated with specific climate variables during years of average to high rainfall throughout most of their range. Instead they appeared to prefer habitats within particular regions. Importantly this study emphasises that conservation measures need to be implemented throughout the distribution of migratory species, including drought refuge habitats and areas outside conservation reserves.

La question des formes narratives, de la représentation et de la lecture dans le roman anglais postmoderne s'inscrit dans une perspective qui vise à relier la pratique littéraire et artistique au contexte historique et culturel postmoderne de la fin du vingtième siècle. Ce contexte est caractérisé par un sentiment d'incertitude et de doute. En rapport avec ceci, l'étude est centrée sur les stratégies de déstabilisation de la représentation réaliste et des modes la construction du sens. En effet, le roman anglais postmoderne remet en question le sens commun qui constitue le fondement de l'écriture réaliste qu'elle soit histoire, biographie ou fiction. La principale stratégie consiste en l'introduction, parallèlement au récit réaliste, d'une version du principe d'incertitude et d'un discours interrogatif qui vise à désintégrer les notions communes et insoupçonnées du langage comme véhicule neutre, de la réalité et de la subjectivité comme étant saisissables et (re)présentables. La subversion des habitudes de lecture (et d'écriture) qui en résulte implique une problématisation des principes téléologiques qui déterminent nos rapports au texte et au mondeThis thesis is concerned with questions of form, representation and the reading process in the English postmodern novel. The idea is to relate the postmodern novel of the last decades of the twentieth-century to a historical and cultural (post-industrial, postmodern and post-humanist) context characterized by a general feeling of uncertainty and doubt. Related to this is the study of the destabilizing strategies of realist representation and of the common modes of meaning-construction. In fact, postmodern English fiction calls into question the common sense basis of realistic writing be it historical, biographical or fictional. The principal strategy consist in introducing, parallel to a realistic narrative, a version of the uncertainty principle and an outward interrogative discourse that seeks to subvert familiar notions of language, reality and subjectivity. The resulting subversion of the reading (and writing) habits implies a problematizing of the teleological principles that determine our relationships with text and world

Full textAbstract:
This thesis documents my investigations into the factors that constrain
reproduction in the endangered swift parrot, Lathamus discolor. First, I have
described the annual cycle of reproduction in the swift parrot, by examining changes
in the gonads and reproductive hormones (oestradiol and testosterone) of both
captive and wild birds. Reproductive development in wild swift parrots initiated after
the birds migrated to their breeding grounds in Tasmania from the mainland of
Australia. Male swift parrots commenced testes development and increased the
plasma concentration of testosterone in all years of the study regardless of the
foraging resources available. Reproductive activity in male birds peaked in October
and November and gonadal regression occurred in late December and January
associated with the development of moult. However, in this period very few female
swift parrots were reproductively active. The female swift parrots' initiation of
breeding appears to be the major factor limiting reproduction in wild swift parrots.
Further, the female birds appear to be limited in numbers as well as opportunities to
breed. There is a male sex bias (1.9:1) to the wild swift parrot population based on
the examination of birds killed in window strikes and birds trapped by mist-netting.
The origins of the sex bias were not determined.
In captive swift parrots, I examined the period of reproduction that- encompasses egg laying, egg incubation and chick-rearing. The male swift parrot is
solely responsible for the provision of resources to the female during incubation and,
in the first two weeks after hatching, to the female and the chicks. This period
appears to be a bottle-neck for food resources in the swift parrots' life history. To
Maintain the high demand for food resources, nesting must occur in close proximity
to good foraging resources.
Next, I investigated links between reproduction and nutrition in swift parrots.
I examined the morphological adaptations to nectarivory that have evolved in the
birds, the food resources used in the breeding season and their ability to extract
protein from ingested pollen; all provide evidence for the importance of the
flowering of the Tasmanian blue gum, Eucalyptus globulus, to supporting the
nutritional requirements of reproduction in swift parrots. I commenced feeding trials in captive birds to examine links between reproduction and dietary energy and
protein. However, these trials were disrupted by deaths due to renal disease, which
was worsened by high protein diets. Assessment of plasma concentrations of uric
acid suggests that swift parrots may have lower protein requirements than
granivorous parrots.
Finally, I assessed the constraints that migration may impose on reproduction,
and the causes of mortality in swift parrots during the breeding season. No
physiological preparations for migration were identified in swift parrots. However,
behavioural changes associated with migration were identified suggesting that
migration limits the time available for reproduction and its timing within the year.
Mortality related to collisions with artificial structures, such as windows, fences and
automobiles was identified as a threatening process of increasing importance to the
swift parrot population.
This study has major implications for the conservation of the endangered
swift parrot and suggests promising avenues for future research. Further, it highlights
the paucity of knowledge of the Australian avifauna and the need for scientific
involvement in the management of endangered species.

Anthropogenic habitat change can have serious effects on the viability of animal populations, but some species are more vulnerable than others. However, basic ecological information is often unavailable to inform management of some species because they present major challenges for detailed field research. I studied the breeding biology of the poorly understood, endangered swift parrot Lathamus discolor. Swift parrots are vulnerable to anthropogenic change because their life history traits (tree cavity nesting, migration and predator naivety) expose them to a wide range of threats. This makes them an excellent model for investigating how complex conservation issues impact poorly known species. Using intensive field survey techniques, I monitored swift parrot nests across their entire potential Tasmanian breeding range. I found that swift parrots have specific habitat preferences. In particular, they only used a limited subset of the tree cavities available to them for nesting. Suitable cavities were uncommon at the landscape scale, and common survey techniques used to assess their availability are prone to error. Swift parrots had low breeding site fidelity, and nest cavities were rarely reoccupied between years. Facultative/irruptive movements between rich, ephemeral patches of food explained this result, and breeding areas were occupied or abandoned depending on local conditions. Facultative movements enabled swift parrots to maintain consistent breeding investment and nestling quality irrespective of where breeding occurred. However, the benefits of moving between rich patches became maladaptive when they settled in areas occupied by introduced sugar gliders Petaurus breviceps. Sugar gliders were major predators of adult female swift parrots and their eggs. Sugar gliders were introduced to the Tasmanian mainland in the 19th century but remain absent from several offshore islands where swift parrots breed. When food availability lured swift parrots into sugar glider infested areas, rather than to predator free islands, the predation penalty was severe. These conditions may create an ecological trap, where habitat selection cues (i.e. food availability) become maladaptive. However facultative movements and variable food availability may allow swift parrots to temporarily escape ecological traps when food availability shifts. This variability complicates swift parrot population dynamics over space and time. I propose that in forests degraded by anthropogenic habitat loss and sugar gliders, swift parrot populations are limited by more complex processes than sedentary or philopatric species. Detailed life history data are critical for accurately diagnosing decline and identifying management approaches for threatened, difficult to study species. The conservation problems faced by swift parrots highlight the necessity of detailed field research for understanding the complex, unexpected and synergistic interactions that may affect our less known difficult-to-study endangered species.

Full textAbstract:
Swift Parrots (Lathamus discolour) are an endangered migratory species that breed only in Tasmania. The foraging habitat available for the species is fragmented and in decline, and continued tree loss is reducing already diminished food resources. The species has been listed as threatened under the Federal Environment Protection and Biodiversity Conservation Act (EPBC Act) since 1999, and the Tasmanian Threatened Species Protection Act since 1995. The aims of this thesis was to assess how Federal and State threatened species legislation acts to protect the habitat of the Swift Parrot in Tasmania, how effective it is at achieving this outcome, and to make suggestions on possible improvements to the system. This was achieved through three case studies examining the removal of key foraging habitat of the Swift Parrot, E. globulus woodland and forest. The first case study, focusing on forestry operations in Tasmania through an examination of the Wielangta case, found that the Tasmanian Regional Forestry Agreement offers scant protection to threatened species. The second case study looked at a property development in Sandy Bay, which demonstrated the management of threatened species habitat is too onerous a task to be taken on by a local planning authority. The third case study of two associated infrastructure upgrades in south-east Tasmania referred to Environment Australia, demonstrated that the removal of 1000 trees crucial to a threatened species does not constitute a “significant impact” under the EPBC Act, so long as the loss is offset. Additionally the number of large E. globulus removed since the enactment of threatened species legislation in Tasmania was measured from remote sensing imagery. Four hundred and ninety four trees were found to have been removed in the study area, with 87% of the loss in Kingborough and 75% in Hobart due to urban development. Recommendations include removal of the exemption provided to RFA from the EPBC Acts assessment and approval process, and reform to the definition of “significant impact” on threatened species to ensure developments are assessed appropriately. Additionally it is recommended that a regional planning authority be establishment to alleviate part of the burden on local councils of threatened species management. Finally improvements should be made to the regulatory system to prevent unnecessary tree removal in urban areas.

Conservation of highly mobile resource specialists depends on
understanding where and
when resources are available and how populations respond to
resource configuration.
These species are often resource specialists, which can make them
vulnerable to resource
bottlenecks in time and space. When they also have dynamic
distributions, data collection
and conservation planning is extremely challenging. Therefore,
for species like the swift
parrot, which is a highly mobile resource specialist with a
dynamic distribution,
ecologically relevant and spatiotemporally explicit estimates of
distributions are urgently
needed to guide conservation planning.
Prior to this research little was known of spatiotemporal
variation in the distribution of
the critically endangered migratory swift parrot in its breeding
range. The swift parrot
requires co-occurrence of two key functional habitats to breed
(nesting and foraging) and
relies on the flowering of Eucalyptus globulus and E. ovata for
food. The overall aim of
this research was to better understand and quantify the spatial
ecology of the species to
improve conservation planning and outcomes. The main impetus for
this research was
continuing extensive habitat loss (as a result of
industrial-scale logging and land
clearance) without an understanding of i) the importance of the
loss of key sites or
locations and ii) the implications of the discovery of novel
predator during the course of
the study.
Firstly, this thesis quantifies and describes a key functional
habitat feature (i.e. nesting
trees) to assist accurate identification of nesting habitat
(Chapter 2). The research then
uses data from a unique multi-year monitoring program to i)
extend modelling approaches to account for imperfect detection
and spatial autocorrelation, ii) quantify the strong link between
changing food availability and the species distribution, and
iii)quantify how this varies over time (Chapter 3). Then, using
data sampled from each functional habitat the research quantifies
annual change in the use, location and availability of functional
habitats over the entire breeding range (Chapter 4). Finally,
the
abundance-occupancy relationship (AOR) is quantified temporally
and spatially to better understand the implications of
spatiotemporal changes in abundance and resource availability for
the interpretation species distribution models (SDMs) (Chapter
5).
This research reveals highly aggregated nesting behaviour of the
swift parrot at multiple
spatial scales, and provides one of the first macroecological
examples to quantify a direct
link between the spatiotemporal distribution of a highly mobile
species and food
availability. This spatiotemporal variation in food not only
means the availability of
functional habitats can vary dramatically between years, but also
that an increase or
decrease in one functional habitat does necessarily correspond to
a relative increase or
decrease in the other. This has important ramifications for
interpreting SDMs, identifying
when and where resource bottlenecks may occur, and the assessment
of exposure to other
spatially variable threats (e.g. predation). Further, the
research shows the AOR for mobile
species in dynamic distributions can be highly variable over time
and space. Importantly, the results also highlight that locations
with high predicted occupancy and/or abundance do not necessarily
equate to areas of high quality habitat. This thesis delivers
some of the first fundamental and quantitative insights into the
spatial ecology of highly mobile species that rely on variable
environments, and provides guidance towards informing and
developing conservation plans for this difficult to study group
of species.

Full textAbstract:
Remnant trees in suburban areas constitute potential habitat for vertebrates by providing food and nesting sites. Trees, including the Tasmanian Blue Gum (Eucalyptus globulus) and Black Gum (E. ovata), are known to supply nectar and pollen to the endangered Swift Parrot (Lathamus discolor), whose breeding success depends on flowering of these two eucalypt species. The outer Hobart suburb of Mount Nelson, Tasmania, is one of the foraging grounds that the Swift Parrot utilises during its breeding season.
The aim of the project was to investigate the relative value of large E. globulus and E. ovata in the bush and suburban areas of Mount Nelson as foraging habitat for Swift Parrots, and to examine which characteristics of the trees and their location affected flower production. In addition, the study investigated the recent and current trends of tree removal from private properties, as well as future plans for tree felling, in order to determine whether the forage sources for the Swift Parrot are declining within the suburb.
From a sample of 261 randomly selected large E. globulus and E. ovata trees ( greater than 60 cm in diameter at breast height) in Mount Nelson, it was found that suburban trees produced more flowers than their edge or bush counterparts. Hence, the former are more reliable nectar and pollen sources for a range of nectarivorous birds, including the Swift Parrot. It is thus argued that suburban trees do not just provide a secondary (to bushland) food supply for Swift Parrots, but constitute an important foraging habitat in their own right outside bush areas. Bush trees, however, despite being less important in providing food to the Swift Parrot, were more likely to support a greater number of nesting hollows for the species.
The study found that the abundance of flowers produced was significantly related to a number of tree variables. Trees with denser canopies, of better health, with no or a low percentage of branches in the canopy that were dead, and no fire damage were likely to support more flowers. The impact of fire was at least partially mediated via its effect on increasing tree dieback and the percentage of branches that were dead, and to a lesser degree, reducing canopy density.
A survey of Mount Nelson residents suggests that many large E. globulus and E. ovata occur on private unprotected land of Mount Nelson. However, they are rapidly being removed. An estimated 28.8% of all large E. globulus declared in the survey and 29.9% of E. ovata have either been removed in the past five to ten years, or will be removed in the near future. Hence, the amount of food available to Swift Parrots in Mount Nelson is being reduced. There is thus a need to retain these valuable tree resources. Maintaining trees in the suburbs as foraging habitat, as well as trees in the bush as nesting habitat, could be important for the long-term survival of the Swift Parrot.

AbstractThis paper considers the problem of attitude and altitude control of quadrotors using the sliding mode control theory. The mathematical model of the quadrotor is derived using the Euler-Newton formalism. The sliding-mode is applied to the Parrot Mambo minidrone, which is a strong example of bringing educational robotics to formal (MATLAB, Python, JavaScript), non-formal (Tynker, Blockly, Swift Playground) and informal education. The control considered shows good performance and enhanced robustness.

AbstractStrategies implemented by Jhpiego nationally and in 15 states of India to respond to the COVID- 19 emergency and to counter the devastating impact of the pandemic are discussed. By the time the nationwide lockdown was imposed in March, 2020, Jhpiego’s COVID-19 response strategy was in action. This strategy included strengthening the capacity of the health workforce, supporting the national and the state governments, and ensuring the continuation of essential health services including reproductive health services.Jhpiego mounted a swift multi-sectoral and multi-pronged program to provide technical support for enhancing the preparedness of the healthcare system across 15 states. Training and monitoring activities were conducted using virtual platforms. A decentralized approach was employed to co-design with the community local solutions for health problems. The thrust was on developing community-centered, community-owned, and community-driven programs. Digital technology, including tele-medicine and other innovative solutions, played a key part in these efforts. The program provided technical assistance for building a resilient healthcare system by strengthening governance mechanisms and facility-based preparedness, piloting an integrated disease surveillance system, enhancing the use of data to guide evidence-based decision-making, re-designing public health facilities, and setting-up rapid response teams which could be quickly mobilized to respond to crises.

There has been a transformation from individual work to team work in the last few decades (Ilgen, 1999), and many organizations use teams for many activities done by individuals in the past (Boyett & Conn, 1992; Katzenbach & Smith, 1993). The use of virtual teams has also become common particularly in international organizations and global companies. In light of this growing phenomenon, the traditional definition of “team structure” should be redefined, as part of the model that predicts the influence of the virtuallity and structural levels on processes, social, and tasks, that effect team output. A methodology will later be illustrated to examine the research model and a discussion of preliminary finding. The research contributes to better understanding of virtual teams in hope of improving the teams work in the virtual world. Virtual team design has so far been treated as an afterthought by virtual team researchers. Investigation of team structure in the virtual environment holds significant promise for research and practice (Powell, Piccoli, & Ives, 2004). Integration between virtual teams and structural characteristics raises the question: “Has the virtual era put an end to team structure?” Leavitt (1996) claims that the rapid changes impose organizations to relax structures. Hackman (2002), on the other hand, predicts that team structure will always exist and managers will continue to be bothered by team design.

Numerous communities of experts supported by firms tend nowadays to form an important part of corporate social capital. Composed of free will agents, those communities aim at creating knowledge through cognitive interactions and heavily rely on ICTs to free themselves from many constraints. Previous studies of such virtual groupings pointed out that their organization features were not similar to market nor hierarchy. Consequently, neither price nor contract or authority are used in such communities which rather seem to self-organize. Instead of traditional economic concepts, notions such as trust and leadership are advanced to explain the functioning of these virtual assemblies. This contribution proposed a tentative model which attempts to grasp some of the empirical aspects of these communities. More precisely, we were interested in the relation between trust, performance, and organizational feature within a given virtual group. Simulations of the model with different functions of swift trust display various organizational structures similar to those described by stylized facts. The organizational attributes range from pure collaborative communities to pure competitive ones. Intermediate cases also emerge with the appearance of leader(s).

The first part considers the general ways in which payment may be effected internationally or across borders in respect of any type of consumer or commercial contract. In many ways, the analysis builds upon the discussion in the earlier chapter dealing with domestic payment systems and limits itself to highlighting the additional issues or concerns that arise when such systems are used to effect an international or cross-border payment. The second part analyses the specialist mechanisms designed to facilitate payment in the trade finance context in particular. Some of the issues surrounding international messaging and transfer systems, such as SWIFT and TARGET, have already been considered.

Full textAbstract:
This chapter’s aim will be to illustrate Joyce’s attempt to textualize his personal experience with illness, through the analysis of a very particular piece of writing, namely the fragment “Twilight of Blindness Madness Descends on Swift”. Placed at the border between private and public writing, the fragment reflects Joyce’s concerns at the time of its composition. Through the evocation of Swift, the fragment reflects an idea of madness as something implied by others as a consequence of fame, but also as a result of a physical exhaustion. In particular, an association in terms of siblings will emerge with which Joyce seems at once to acknowledge their points of resemblances but at the same time reflect the refusal of a complete identification: as this chapter shows, Joyce is projecting himself, or rather his illness, upon an Irish writer with whom he had many points of contact but who is other than him, possibly in the attempt to sublimate his sufferings through writing, reshaping them through the image of Swift’s legendary madness. And this chapter will argue that this fragment, even though never found any space in the final texts, it is nonetheless still part of the compositional process in a wider sense: it coincides with what John Nash has described as “a point of maximum exhaustion, of the materials but also of the writer himself”, which nonetheless represents “a restless point which ensured renewal”.

This chapter explores a contemporary work for contralto by William Mathias. The piece runs in a continuous span, but contains many contrasting sections within it. Although conceived for a rich, low voice, it also requires the lightness and agility to articulate swift staccato passages with aplomb. The highest pitches are at a loud dynamic. Otherwise, the contralto’s strong chest register is exploited rewardingly. A good deal of stamina is required to sustain and conserve energy through a welter of varied gestures and moods, which are enhanced by a striking piano part. The musical language is ‘advanced traditional’. It should prove an excellent vehicle for an enterprising duo able to give an authoritative interpretation. The inspiring text is an additional asset.

Abstract This chapter disposes of the actors and describes several monuments to them that still reward inspection. Consideration of these monuments, which include part of the Vatican museums, makes a fitting conclusion to the book, for, as Bianchini rightly insisted, historians ought not to omit the proofs and delights afforded by depiction of artifacts illustrative of the times they write about. The monuments described include tombs of Maria Clementina, Queen Christina, and Pope Alexander VIII in St Peters and testimonials to Bianchini in Rome and Verona. Among other actors exiting the scene, Wogan remained the most colorful; his later military adventures in Spanish service earned him the governorship of Don Quixote’s province of La Mancha and his literary productions attracted the attention and admiration of Jonathan Swift.

Full textAbstract:
Despite the resolution in the Treaty of Westminster (1654), the Amboyna massacre became entrenched in English culture as a familiar cultural touchstone. Three further wars with the Dutch led to new Amboyna pamphlets. Amboyna also became part of internal political disputes in which Tories wrote Amboyna pamphlets to attack Whig rivals. In a wide-ranging exploration of multiple genres of popular and print culture, including plays, advice manuals, fiction, and library catalogues, this chapter analyzes the many ways in which Amboyna became domesticated in English culture. By the end of the seventeenth century it had shed its political significance as a symbol of ingratitude and instead became a consummate tale of cruelty. It also endured as a tale of unrequited injury. British authors such as Dryden, Defoe, and Swift were part of this process. By the end of the eighteenth century, with a final True Relation, it had become a legend.

Presented is a simulation of an engine cylinder head undergoing water quenching process using a recently developed approach for modeling quenching cooling of metal parts (Wang et al., 2002). The approach is based on the AVL SWIFT Eulerian two-fluid method with special emphasis on handling high mass exchange rate associated with quenching. A tetrahedral grid of 830,000 cells is generated for the computational domain, which includes the solid part of the cylinder head immersed in the fluid. Detailed vapor and temperature distributions are obtained which offer valuable information for the thermal stress analysis. It is observed that the temperature field within the cylinder head is highly non-uniform. The computed cylinder head monitoring point temperature versus time is compared with that registered by the thermal couple measurement. Reasonable agreement is observed. The simulation exercise may potentially be used to identify the cause of cracks often encountered in quenching heat treatment thereby lead to a better design of the process.

Prevention of compressor surge is one of the most important tasks in operation of gas turbine engine. The easiest way to see the phenomena is to show the static and dynamic operation characteristic on the map. Its operation zone will be restricted by the surge limit and, static and transient process must have some margin for it. Surge margin of a static regime is normally chosen during its design stage. Safe operation during part load condition without facing the surge is an indispensable task for control system design and a swift response from the engine is required to avoid it. Effect of rotor moment of inertia, air/gas volumes and heat transfer are factors to cause the transition from the static line. In case a large volume such as heat exchanger exists in the system it will exert a substantial influence to dynamic characteristics. In the present paper, influence of air volume bled from the compressor exit on transient process is investigated with an example of an auxiliary power unit micro-turbine engine. A typical compressor characteristic with scaling was used for the calculation. Turbine mass, pressure ratio, rotation speed, power and moment are calculated based on mass and work conservation. Result from the present study can give a guidance to design the control system. A computer program is developed to calculate the dynamic process using the MathCAD commercial software. Air volume is changed from 0.02 to 6 m3.

Generally, most waterpower plants have to function under energy system peak load operation. Thus, there is a relatively quick water level variation observed in water-storage reservoirs, which contributes to the problems, especially in case of high-pressure waterworks facilities. Swift reservoir draw-down enhances seepage volumetric forces acting from the rock mass, which may lead to rock mass cracking and eventually to the development of landslide processes. A rapid impoundment of the water-storage reservoir is no less damaging. In this case, seepage in the rock mass is progressing in non-steady conditions, there occurring, in the inception stage: - high magnitude seepage hydrodynamic forces at the rock mass surface, creating additional loads on the rock mass, causing deflection of its surface, which may promote dam-foundation contact opening; - with increased pore pressures and seepage gradients, there may occur suffusion and other undesirable processes in the rock mass. In the work is given a numerical analysis of some parameters of seepage mode given based on right-bank investigation admitting presence of break in the dam filling-up mode. Options of time-intervals for the two basic versions – in case of sudden rising of water level in the upstream and in case of slow filling-up and setting up steady-state seepage mode in the massive – are being discussed. Determination of seepage flow parameters (including gradients) requires nonstationary field task to be solved. Finite-elements approximation for time analysis of the task is solved by finite-difference scheme. Seepage calculations are carried out by cyclic-iteration scheme – where volumetric water content, hydraulic conductivity and elasticity module determined numerically by functional relations. The subject of research is Enguri waterpower plant arch dam, at present the highest in the world (Georgia, height 271.5m, fig. 1.1). Consideration is being given to a variety of cases: - canyon slope in the zone of major geological fracture; - foundation in the central part of the dam.

Full textAbstract:
Abstract Open hole Multistage Fracturing (MSF) systems have been deployed for treating open hole formations with multiple, high rate hydraulic fracturing stages while gaining efficiency during pumping operations unlike traditional plug-and-perf operations. One important challenge within the industry was availability of an open hole packer system that can overcome tough wellbore conditions during deployment and function as designed during the high rate high pressure stimulation operations. This paper will discuss the successful planning and deployment of one such system. For successful deployment of any open hole fracturing completion, one must first consider the environment that the system will be deployed into. Lateral length, open hole size, parent casing size and tubing stresses during fracturing and production all inclusively influence the need for a robust and reliable system. Other several important considerations to be deployed as a liner is the compatibility of the completion tools with the Liner deployment system, the robustness of being deployed into challenging open hole conditions where capability of high circulating rates and rotation become mandatory to get the bottom hole assembly (BHA) to its final setting depth. Last but not least, in order to achieve successful stimulation, each component of the system after overcoming all the deployment obstacles should function as designed withstanding treating differentials as high as 15kpsi, while simultaneously accommodating induced axial loads caused by these high-pressure treatments. The development and testing of individual components of the system was done keeping in mind wellbore instability and obstacles the completion will have to overcome during deployment. The field execution was planned with close collaboration with the operator and other key services that were involved for drilling the well. Real-time monitoring of the well allowed for simultaneous swift implementation of changes required on tool activation pressures, identification of hazards and mitigation plan to overcome challenges in order to execute the job successfully. It is worth mentioning that the successful deployment of this system represents the first use of additive manufacturing in high pressure, hydraulic set open hole packers. This technology allowed overcoming the barriers of challenges associated with deploying open hole completion in tight challenging formations that would otherwise have limited deployment capabilities.

В статье автор обращается к дискуссионной в исторической науке проблеме – возникнове-нию ранних политических партий в Англии во второй половине XVII века и становлению двух-партийной системы на рубеже XVII–XVIII веков. На основе анализа произведений современников эпохи – известных деятелей просветительского движения Г. Болингброка, Дж. Свифта, Д. Дефо, Р. Стиля, Дж. Аддисона, маркиза Галифакса делается вывод о существовании в указанный период партий тори и вигов и их борьбе за власть. Ранние политические партии заметно разнились с теми, которые существуют в современном мире. В то же время нельзя сбрасывать со счетов атрибуты, одинаково присущие ранним и современным партиям (партийная пресса, клубы, партийная пропа-ганда во время избирательных кампаний, деятельность идеологов и партийных лидеров). В пользу существования двухпартийной системы в ту пору говорит и наличие как однопартийных, так и смешанных кабинетов министров. К началу XVIII века политические партии заняли прочное ме-сто в структуре государственного правления, а двухпартийная система сделалась неотъемлемой частью конституционного устройства Англии. In the article, the author addresses the problem discussed in historical science – the emergence of early political parties in England in the second half of the XVIIth century and the formation of a two-party sys-tem at the turn of the XVII–XVIIIth centuries. Basing on the analysis of the works of contemporaries of the era – famous figures of the Enlightenment H. Bolingbroke, J. Swift, D. Defoe, R. Style, J. Addison, the Marquis of Halifax, author concludes that the Tory and Whig parties existed in this period and struggled for power. The early political parties were noticeably different from those that exist in the modern world. At the same time, it is impossible to discount the attributes that are equally inherent in early and modern parties (the party press, clubs, party propaganda during election campaigns, the activities of ideologists and party leaders). In favor of the existence of a two-party system at that time, the presence of both single-party and mixed cabinet ministers also speaks. By the beginning of the XVIIIth century, political gained a firm place in the structure of state government, and the two-party system became an integral part of the constitutional structure of England.

Full textAbstract:
Subsea pipelines-deemed as the safest and most efficient means for transporting hydrocarbons, their integrity and long term maintenance are among the highest priorities for the oil and gas industry. These assets have a design life and are susceptible to damage from various factors during its operation. Operators should have in place a comprehensive Emergency Pipeline Repair System (EPRS). The EPRS should entail rigorous measures to minimize loss of production, the potential consequences of catastrophes and adverse effects on environment in case of an unforeseen event such as pipeline rupture or spill. The system should ensure swift response to restore the mechanical integrity of a damaged section whilst maintaining high HSE standards and minimizing the production shutdown-time duration. Accidental damages call for remedial response actions on an emergency basis. Considering short lengths of pipeline to be replaced, tow technique can offer an effective alternative to the time consuming and expensive conventional pipe-lay barge operations. An installation method constituting the tow technique is proposed as a part of EPRS to replace damaged section of an operational pipeline. The paper discusses the applicable scenarios, the installation criteria and operational constraints involved in entire set of activities based on the study undertaken. The scenario analyzed involves launching a pre-fabricated pipe string offshore, towing and lay down at repair location. The pipe string is launched from an onshore facility by means of a lead tug, facilitated by rollers placed at designed intervals. The onerous task of pulling the pipe strings through long stretches of shallow water depths emphasizes the need of neutrally buoyant or slight positively buoyant pipe strings. Placing roller supports for the entire stretch is likely to pose several practical and economic constraints. The pipe string is towed to the intended offshore repair location with the assistance of a trailing tug. The pipe strings are laid down at the intended location in a controlled manner by means of winches and sequential release of buoys. Numerical models of the system for towing and laydown operations are developed and related investigations are undertaken to evaluate the installation parameters, supplementary buoyancy requirements and to assess the criticality at various stages of installation. Further, the limiting weather criteria to carry out the operation are established based on the wave and current imposed hydrodynamic loadings on the strings and several governing parameters. The paper also briefs merits and limitations of the method.

Full textAbstract:
Abstract Objective / Scope The main objective of the paper to showcase PDO successful journey in transferring Continuous Improvement (CI) knowledge to targeted entities within the government of the Sultanate of Oman by building CI capabilities to deliver significant improvement activity. Effectively after signing the MOU with Oman Vision 2040 Unit in 2019 for 5 years, a full CI transformation program kicked off to change the culture of the public sector from the inherited bureaucracy of which has the top leader is the showman, to a new way of working where the top leaders considered as the enabler of the progress (the main sponsor), wearing the learner hat, to understand the challenges from the front line of the business, be able to coach them to achieve their goals with minimal influence to their day to day work and huge encouragement to break down walls having them reach towards their desired destination. This supports the government's target to position Oman as an attractive environment for ease of doing business & the deployment plan focuses on building local CI capability within each entity, replicating improvements across the other entities, sustainability, and Leadership coaching. Methods, Procedure, Process Petroleum Development Oman (PDO) has more than 10 years' experience in the journey of Continuous Improvement. The experience is healthy with inflections and corrections over the course of progress until it covered all the organization vertically and horizontally. In 2020 it covered all functions and reached two level of categories spanning all staff: CI Professionals and CI Generalist. This concept and culture change can't be simulated into the government as is. It had to go through some modification for easy adoption and faster implementation. Building individual skills takes its own course of time, so the CI Professionals of PDO were posted into the core government system, the Oman Vision 2040 Implementation and Follow-up Unit. This allows immediate impact into the system and swift digital transformation to the centralized dashboard reviewed by leadership to sustain improvements. While the transformation takes place, PDO takes internally, 15 highly competent individuals from different government entities, as a secondment for 3 years development program to become accredited CI coaches and ultimately take their learning back to their organizations. Additionally, PDO provided the nation with a free online access to one of the problem-solving methodologies "Lean Awareness". This online session is developed to support a nationwide buy-in as part of the change management efforts to increase the awareness of continuous improvement. Results, Observation, Conclusions The high-level value delivered by the CI Deployment in the Government can be sampled from any of the CI projects delivered, E.g., the 90% improvement to the 'starting a new business process'. The overall scale, scope, and speed of improvement projects across the government entities is unprecedented. However, value is much more than the process improvements, such as: PDO Omani expertise being utilized to accelerate CI Capability across the Government. Improving starting business process by 90% from 10 months to 1.25 months. To "Lean" over 100 government services in 12 different entities by end of 2021. PDO improved cross-organization process with Government Entities E.g. Environment Authority permits, Manpower etc. Accelerating the progress of National Digital Transformation Program led by Ministry of Transport, Telecommunication & Information Technology. Build in house and sustainable capability for the government sector. Overall, the value to PDO, the Government and Oman is priceless for the longterm sustainability of the country. Novel, Additive information This initiative has had a hugely positive impact on PDO & Oman in the last 3 years and will continue to do so, moving towards end of 2022 and beyond the project team is working closely with Oman e-government team to assist the government to shift from egovernment to Digital government to Smart government - a real game changing innovative shift for Oman. This project is a true example of how Omani expertise developed and nurtured within PDO is being used to power Oman towards vision 2040 and is a fantastic example of our organization creating in-country value.

New evidence suggests that over four months after the closure of early childhood development (ECD) programmes on 18 March 2020, the ECD sector was likely to be operating at less than a quarter of its pre-lockdown levels. Of the 38 percent of respondents from the new NIDS-CRAM survey reporting that children aged 0-6 in their households had attended ECD programmes before the lockdown in March, only 12 percent indicated that children had returned to these programmes by mid-July, well after programmes were allowed to reopen. Using these findings, we estimate that just 13 percent of children aged 0-6 were attending ECD programmes by mid-July to mid-August compared to 47 percent in 2018. The last time that ECD attendance rates were as low as this was in the early 2000s. At this point it is not yet clear what proportion of these declines are only temporary, or whether there will be a lasting impact on ECD enrolment in the country. This dramatic contraction in the ECD sector relates to prohibitive costs to reopening ‘safely’ imposed by the regulatory environment, coupled with shocks to the demand side for ECD programmes (both in terms of reduced household incomes and parent fears of children contracting COVID-19). When viewed from a broader socio-economic lens, the threat of ECD programme closures across the nation will have impacts beyond ECD operators to the lives of millions of children, millions of households and millions of adults who rely on these ECD services. A swift intervention by government is necessary to save this important sector and limit the ripple effect of programme closures on multiple layers of society.
