In this paper we study the relationships between local and global properties in networks of dynamical systems by focusing on two global properties, synchronization and peak-to-peak dynamics, and on two local properties, coherence of the components of the network and coupling strength. The analysis is restricted to networks of low-dimensional chaotic oscillators, i.e. oscillators which have peak-to-peak dynamics when they work in isolation. The results are obtained through simulation, first by considering pairs of coupled Lorenz, Rössler and Chua systems, and then by studying the behavior of spatially extended tritrophic food chains described by the Rosenzweig–MacArthur model. The conclusion is that synchronization and peak-to-peak dynamics are different aspects of the same collective behavior, which is easily obtained by enhancing local coupling and coherence. The importance of these findings is briefly discussed within the context of ecological modeling.

Full textAbstract:
The local search algorithm WSat is one of the most successful algorithms for solving the satisfiability (SAT) problem. It is notably effective at solving hard Random 3-SAT instances near the so-called `satisfiability threshold', but still shows a peak in search cost near the threshold and large variations in cost over different instances. We make a number of significant contributions to the analysis of WSat on high-cost random instances, using the recently-introduced concept of the backbone of a SAT instance. The backbone is the set of literals which are entailed by an instance. We find that the number of solutions predicts the cost well for small-backbone instances but is much less relevant for the large-backbone instances which appear near the threshold and dominate in the overconstrained region. We show a very strong correlation between search cost and the Hamming distance to the nearest solution early in WSat's search. This pattern leads us to introduce a measure of the backbone fragility of an instance, which indicates how persistent the backbone is as clauses are removed. We propose that high-cost random instances for local search are those with very large backbones which are also backbone-fragile. We suggest that the decay in cost beyond the satisfiability threshold is due to increasing backbone robustness (the opposite of backbone fragility). Our hypothesis makes three correct predictions. First, that the backbone robustness of an instance is negatively correlated with the local search cost when other factors are controlled for. Second, that backbone-minimal instances (which are 3-SAT instances altered so as to be more backbone-fragile) are unusually hard for WSat. Third, that the clauses most often unsatisfied during search are those whose deletion has the most effect on the backbone. In understanding the pathologies of local search methods, we hope to contribute to the development of new and better techniques.

Abstract. Ice core nitrate concentrations peak in the summer in both Greenland and Antarctica. Two nitrate concentration peaks in one annual layer have been observed some years in ice cores in Greenland from samples dating post-1900, with the additional nitrate peak occurring in the spring. The origin of the spring nitrate peak was hypothesized to be pollution transport from the mid-latitudes in the industrial era. We performed a case study on the origin of a spring nitrate peak in 2005 measured from a snowpit at Summit, Greenland, covering 3 years of snow accumulation. The effect of long-range transport of nitrate on this spring peak was excluded by using sulfate as a pollution tracer. The isotopic composition of nitrate (δ15N, δ18O and Δ17O) combined with photochemical calculations suggest that the occurrence of this spring peak is linked to a significantly weakened stratospheric ozone (O3) layer. The weakened O3 layer resulted in elevated UVB (ultraviolet-B) radiation on the snow surface, where the production of OH and NOx from the photolysis of their precursors was enhanced. Elevated NOx and OH concentrations resulted in enhanced nitrate production mainly through the NO2 + OH formation pathway, as indicated by decreases in δ18O and Δ17O of nitrate associated with the spring peak. We further examined the nitrate concentration record from a shallow ice core covering the period from 1772 to 2006 and found 19 years with double nitrate peaks after the 1950s. Out of these 19 years, 14 of the secondary nitrate peaks were accompanied by sulfate peaks, suggesting long-range transport of nitrate as their source. In the other 5 years, low springtime O3 column density was observed, suggesting enhanced local production of nitrate as their source. The results suggest that, in addition to direct transport of nitrate from polluted regions, enhanced local photochemistry can also lead to a spring nitrate peak. The enhanced local photochemistry is probably associated with the interannual variability of O3 column density in the Arctic, which leads to elevated surface UV radiation in some years. In this scenario, enhanced photochemistry caused increased local nitrate production under the condition of elevated local NOx abundance in the industrial era.

ABSTRACT The clustering of local extrema will be exploited to examine Gaussianity, asymmetry, and the footprint of the cosmic-string network on the CMB observed by Planck. The number density of local extrema (npk for peak and ntr for trough) and sharp clipping (npix) statistics support the Gaussianity hypothesis for all component separations. However, the pixel at the threshold reveals a more consistent treatment with respect to end-to-end simulations. A very tiny deviation from associated simulations in the context of trough density, in the threshold range ϑ ∈ [−2–0] for NILC and CR component separations, are detected. The unweighted two-point correlation function, Ψ, of the local extrema illustrates good consistency between different component separations and corresponding Gaussian simulations for almost all available thresholds. However, for high thresholds, a small deficit in the clustering of peaks is observed with respect to the Planck fiducial ΛCDM model. To put a significant constraint on the amplitude of the mass function based on the value of Ψ around the Doppler peak (θ ≈ 70–75 arcmin), we should consider ϑ ≲ 0.0. The scale-independent bias factors for the peak above a threshold for large separation angle and high threshold level are in agreement with the value expected for a pure Gaussian CMB. Applying the npk, ntr, Ψpk − pk and Ψtr − tr measures on the tessellated CMB map with patches of 7.52 deg2 size prove statistical isotropy in the Planck maps. The peak clustering analysis puts the upper bound on the cosmic-string tension, Gμ(up) ≲ 5.59 × 10−7, in SMICA.

Full textAbstract:
This thesis provides a critical review of the Transition movement, a grassroots response to peak oil and climate change, co-founded by this author. It focuses on two key aspects of the Transition approach, resilience and economic relocalisation, with the aim of analysing whether and how they can be implemented in a locality based on the Transition approach, and assessing what socio-economic and community-related structures would be necessary to implement such a process. The focus of the research is Totnes, Devon, which because of its status as the UK’s first Transition initiative and the longer history of various initiatives to promote local resilience, offers a valuable case study of attempts to practically implement resilience and localisation. A variety of research methods were employed, including surveys, focus groups, oral history and in-depth interviews, as well less conventional public participation methods such as Open Space and World Café. The first major finding was that Transition Town Totnes (TTT) has become a significant organisation in the town, with a high level of popular support. It was also found that the obstacles to resilience and relocalisation lie not, as was hypothesised, in a lack of skills or an absence of community cohesion, but in issues of governance and the need for increased social entrepreneurship. It was found that what researchers call the ‘Value Action Gap’ (i.e. the gap between people’s declared sympathies and intentions and their actions) exists in Totnes as much as anywhere else, but that some of TTT’s projects, such as ‘Transition Together’, are working imaginatively to overcome this and to reduce emissions. From this evidence is it concluded that Transition’s approach towards relocalisation and reducing carbon emissions can be argued to be effective in, generating engagement and initiating new enterprises. Like other ‘green’ initiatives, it struggles to engage those from more disadvantaged backgrounds, but some of its initiatives are showing promise for overcoming this. Its primary contribution is in suggesting a redefining of resilience, not as a state of preparedness for disaster, but as a desired characteristic of a sustainable society. A more resilient community, it is argued, would be one more in control of its food and energy production, as well as being one that enables inward financial investment. It also argues that the government focus on ‘localism’, the devolving of political power to the local level, ought to be expanded to include ‘localisation’, the strengthening of local production to meet local needs, a shift which would financially benefit local communities. It argues that the key challenge for Transition initiatives such as TTT is going to be scaling up from being ‘niche’ organisations to become economically viable organisations with a broad appeal and engagement, and also articulates the need for ‘Resilience Indicators’ which would allow communities to measure the degree to which their levels of resilience are increasing.

Full textAbstract:
In this thesis, I examine the ways in which the local identity as "the Plague Village" that has been built up in Eyam over the centuries intersects with heritage tourism and the local heritage museum in telling the story of Eyam's history with bubonic plague. The key areas of investigation are: 1) tourism in Eyam and the interactions between visitors and village residents, 2) the role of the local museum and other heritage projects in defining and constructing Eyam's public identity, 3) the secondary function of the museum as a memorial site, 4) the strategies employed by the museum in the design, display, and presentation of its exhibits, 5) the specific ways in which the museum describes and displays "the Plague", and 6) the issues surrounding a specific aspect of the Plague discourse addressed in the museum, the CCR5-Delta32 genetic mutation, which was the subject of genetic testing in Eyam to study its possible connection to surviving bubonic plague. Drawing on tourism research and heritage tourism studies, museum anthropology, anthropology of science, and medical anthropology, I show the interconnectedness and the complexity of heritage tourism in Eyam and the ways in which Eyam Museum contributes to this. Key Findings: 1) Heritage tourism is far more complex than can existing theories regarding "the gaze" suggest, and in Eyam, we see that the gaze is part of the picture, but the work of the imagination and the attempt by visitors to physically place themselves within the history they seek to learn about by walking particular routes and visiting particular spots are equally important in understanding the driving force behind the type of heritage tourism found in Eyam. 2) The museum is a very powerful driving force in Eyam's tourism, and it is the museum which determines what story is told to visitors and in what ways. It tells a history, but it also serves as a memorial to the people who died in Eyam's Plague outbreak, acting in some ways as a sacred site rather than as simply a museum. 3) Eyam Museum uses a variety of display formats, including dioramas, artefacts in glass cases, charts and graphs, drawings, and text panels. Its heavy use of text panels and its distinct lack of interactive displays differentiate Eyam Museum from other museums in Britain and in museum studies literature, but the museum's memorial function combined with lack of space and low budget mean that interactive displays are not being considered as an option at this time. 4) The Plague and "the gene" are seen as biomedical concepts in some ways, illustrated through a variety of methods, but at the same time, they are seen in social terms, as the Plague is the story of great suffering and loss for the village that is associated with specific names and individuals' life stories, while "the gene" is considered as an object of hope and amazement for its relationship not to bubonic plague, but to HIV, a "modern-day plague", making this part of the story told in the museum relevant and exciting to visitors to Eyam today.

Full textAbstract:
This study aims to investigate the stable isotopic characteristics of meteoric and ground waters, and to obtain spring flow rates in the Coronet Peak Skifield, Queenstown. Spring flows were gathered during the winters of 2008 and 2009, whilst water samples were collected from precipitation, springs, reservoirs and groundwater during July, August and September 2009. The spring flows were examined and the water samples were analysed for δD and δ¹⁸O values using the CF-IRMS at the University of Canterbury.
A database has been gathered from all natural water sources to give a local meteoric water line (LMWL) for the area that fits clearly with the global meteoric water line. The LMWL has an R2 value of 0.97 and the equation is δD = 8 δ¹⁸O +10. An understanding of evaporation as it occurs in the water storage reservoirs of the mountain has also been obtained, giving rise to a local evaporation line.
The stable isotope ratios of hydrogen and oxygen within precipitation have been used extensively to characterise the hydrogeology with emphasis on altitude effects, storm duration and variations in storm track trajectories. Of these three phenomena, it is the trajectory of the storm track that is best shown to affect the composition of precipitation in this area. The air masses advancing on the study area from the north being more depleted in their isotopic signatures, with approximate δD and δ¹⁸O values of –130‰ and -16‰. The air masses approaching from a southerly direction are more positive in comparison, having approximate δD and δ¹⁸O values of –65‰ and -9‰.
The altitude effect in precipitation on the Skifield has led to an altitude gradient being found: for every 100-metre increase in elevation, δ¹⁸O decreases by 0.71‰. However there were some inconsistencies. The influence on precipitation from storm duration is also inconsistent in this area. The R2 values range from 0.14 to 0.99, but this method does not take into account the position of the individual samples. Some samples did not plot in the expected order that is governed by a decrease in stable isotopic ratios with storm duration.
The stable isotopic compositions within meteoric waters can be used as tracers of water sources. The isotope date of the springs also infers an altitude effect. The
springs gave an altitude gradient of a decrease –0.43‰ with each 100-metre increase in elevation. This indicates that precipitation is the main influence on the stable isotopic composition of the springs in this area. However, data shows differences between the current precipitation and the groundwater compositions, indicating that present precipitation is not flowing from the springs, past precipitation is. The stable isotopic compositions of the springs have also been correlated with groundwater isotope data and suggest the sources of the springs are groundwater dominated. Although some springs compositions indicate an influence by current precipitation. This is shown by a negative stable isotopic trend in the precipitation sampled in August, corresponding with a relatively negative stable isotopic composition in some springs during this time period.
Monitoring of spring flows on Coronet Peak have led to an average winter flow rate being established of 26.5 litres per second. Spring flow rates range from 0.25 – 6 litres per second. This monitoring has indicated the springs of the greatest yield that are not already being utilised on the Skifield. It is these springs that should be further investigated as to whether they would provide a sustainable source of water on the mountain. This locally derived water would then be utilised for the purposes of artificial snowmaking and other activities and amenities that are currently operated by NZ Ski on Coronet Peak.

Full textAbstract:
This thesis employs a case study approach to investigate local implications of globally restricted mobility by examining Queenstown’s vulnerability to peak oil and climate change. Qualitative research methods are the principal means of inquiry. The research findings suggest that Queenstown is particularly vulnerable to peak oil and climate change at a broad scale because of its dependence on tourism and heavy reliance on air transport. However, Queenstown has fortuitously built up resilience to peak oil and climate change through tourism industry diversity, comparative advantage and an increasing proportion of short-haul visitors. A selection of key Queenstown tourism stakeholders interviewed as part of the research demonstrated some grasp of peak oil and climate change issues but lacked in-depth understanding. They generally considered the issues as being beyond their control although several suggested ways that Queenstown could strengthen resilience to peak oil and climate change. In terms of solutions, this research identifies three potential strategies. The first involves investing in a low carbon local transport system to increase destination level resilience to peak oil and climate change and enhance the uniqueness of the Queenstown brand. The second involves Queenstown promoters targeting the high-end niche tourism market in order to create a more resilient visitor profile. And the third involves the creation of new and expansion of existing industries not tied to tourism – preferably industries that are not excessively oil dependent and carbon intensive. But in order to successfully tackle the problem, it is imperative to first raise awareness. The research recommends implementing a framework that ensures an inclusive community-wide open dialogue process as the most effective way to achieve this.

It was an industrialised region that experienced high levels of unemployment in the period. These were greater than the State and national averages, which reflected a geographical concentration of unemployment in certain regions in Australia. The SCLC attempted to address this issue, as it was part of the union structure that was specifically focused on the regional level and on regional concerns. The study argues that the SCLC developed a local employment generation strategy and it examines how and why this was adopted and pursued. It finds that the SCLC was well placed at the regional level and was well resourced with a capacity to influence the external environment through its utilisation of both political and industrial methods in a period of agreeable internal relations. The research identifies the development of its local employment generation strategy. Sometimes the SCLC pursued its strategy in a manner of ad hoc decision-making and muddling through, while at other times it involved characteristic and distinctive regular patterns. The thesis concludes by evaluating the SCLC�s strategy of local employment generation and by exploring the applicability of the general trade union literature on methods and strategy to regional labour councils.

Full textAbstract:
Globalization and industrial agriculture have enabled consumers in Sweden and other countries in the Western world to enjoy foodstuffs from many parts of the world at very affordable monetary prices, but at the same time involving a lot of external costs in the form of environmental degradation, and a high dependency on foreign agricultural ecosystems as well as on oil and other non-renewable inputs, thus degrading sustainability and resilience in the food system. Accelerated climate change and the upcoming peak oil crisis call for a reorientation and a transition to a more locally-based system. The prospects for a re-localized food system have been investigated in a case study of Uppsala Municipality, Sweden. The results consist of a study of the current primary food production in Uppsala, also including an allotment garden survey, a study of how much additional food may be produced on idle land, and an analysis of opportunities and challenges for a re-localized food system in Uppsala. The allotment garden survey revealed that c. ten percent of the total area of plots containing cottage houses was used for food production, while the figure for plots without cottages was several times higher, c. 65 percent. The total estimated yield for allotment gardens in Uppsala Municipality was about 90 tons of vegetables and 48 tons of fruits and berries. Quantitative calculations on the yield produced by local farmers, horticulturists and leisure gardeners were made for the five categories grain, dairy products, eggs, meat, and vegetables, fruits and berries, together constituting about 85 percent of the total Swedish food consumption. The estimated balance of supply and demand differed a lot between food categories, ranging from 400 percent for grain to 20 percent for meat as well as for vegetables, fruits and berries. Due to empirical uncertainty, the latter figure should be interpreted with caution. For eggs and dairy products the balance of supply and demand was 67 percent and 50 percent respectively. A quantitative estimation for idle land showed that the greatest potential for an increased food production is within leisure gardening, which could be increased by 3.5 to 6 times. A transition to full self-sufficiency would, however, require drastically altered consumer habits towards seasonal vegetables and fruits and less beef in favor of vegetarian proteins. The qualitative analysis of possibilities and obstacles concluded that the greatest assets for a re-localized food production were the large production capacity within rural agriculture, the abundance of mostly unutilized private garden land, the increased interest for urban agriculture among the population, positive attitudes among consumers towards local food, and a relatively high general awareness of climate change and the need for a more sustainable society. Among the challenges were found lacking economic viability and access to suitable farmland, the centralized food industry, an imbalanced agricultural output, unsustainable consumer habits, the tendency among Swedish municipal planners to support exploitation of fertile soil, and a low awareness among both the population and decision makers regarding peak oil and social resilience generally.Globaliseringen och det industriella jordbruket har möjliggjort för konsumenter i Sverige och andra västländer att få tillgång till matvaror till låga priser och från många olika delar av världen. Samtidigt har detta medfört ett högt pris i form av miljöförsämringar och ett stort beroende av utländsk jordbruksproduktion, samt av olja och andra råvaror som inte är förnybara. Resultatet har blivit ett livsmedelssystem med urholkad hållbarhet och ökad sårbarhet. Accelererande klimatförändringar och den kommande krisen i samband med oljetoppen manar till nyorientering och en övergång till ett mer lokalbaserat system. Denna fallstudie av Uppsala kommun har undersökt utsikterna att återknyta matproduktionen till lokala system. Resultaten omfattar både en studie av den nuvarande matproduktionen i Uppsala, vilken även inkluderade en enkätundersökning av kolonilotter, en studie av potentialen att öka matproduktionen på mark som idag inte används aktivt för det ändamålet, samt en analys av möjligheter och utmaningar för en lokal matproduktion i Uppsala. Enkätundersökningen visade att på kolonilotter med stugor användes ca tio procent av den totala ytan för matproduktion, medan motsvarande siffra för kolonilotter utan stugor var flera gånger högre, ca 65 procent. Den totala skörden för alla kommunala kolonilotter i Uppsala uppskattades till 90 ton grönsaker och 48 ton frukt och bär. För den totala matproduktionen från jordbruket, trädgårdsnäringen och fritidsodlingen gjordes beräkningar för fem olika kategorier: Spannmål, mejeriprodukter, ägg, kött samt grönsaker, frukt och bär, som tillsammans utgör ca 85 procent av den totala svenska matkonsumtionen. Den uppskattade försörjningsbalansen varierade starkt mellan olika kategorier, från 400 procent för spannmål till 20 procent för kött samt för grönsaker, frukt och bär. Osäkerheten kring det vetenskapliga underlaget gällande fritidsodlingen är dock stort, vilket gör att siffrorna för grönsaker, frukt och bär bör tolkas försiktigt. För ägg och mejeriprodukter var försörjningsbalansen 67 procent respektive 50 procent. Studien av obrukad mark visade att den största potentialen för en ökad matproduktion finns inom fritidsodlingen, som beräknades skulle kunna öka med 3.5 till 6 gånger. En övergång till full självförsörjning skulle dock kräva drastiska förändringar i konsumtionsvanorna mot säsongsbetonade grönsaker och frukt samt mindre nötkött till förmån för mer vegetabiliskt protein. Analysen av möjligheter och utmaningar för en återgång till en mer lokal matproduktion pekade på att de största fördelarna är den stora produktionskapaciteten inom jordbruket, den stora sammanlagda arealen privat trädgårdsmark som till stor del är outnyttjad för matproduktion, det ökande intresset för stadsodling bland befolkningen, positiva attityder till lokal mat bland konsumenter, och en relativt hög medvetenhet kring klimatförändringar och behovet av ett mer hållbart samhälle. Bland de viktigaste utmaningarna fanns den bristande ekonomiska lönsamheten inom yrkesodlingen, den centraliserade livsmedelsindustrin, obalansen inom jordbruksproduktionen, med överskott på spannmål och underskott på andra livsmedelsråvaror, ohållbara konsumtionsvanor, tendenser hos svenska kommunala tjänstemän att stödja exploatering av bördig mark, samt den låga graden av medvetenhet hos både befolkningen och beslutsfattarna kring oljetoppen och samhällets sårbarhet generellt.

Full textAbstract:
Toxins produced by the Gram-positive bacteria Clostridium botulinum cause transient chemodenervation of mammalian muscle. The toxin binds to specific proteins within cholinergic presynaptic nerve terminals which regulate the release of acetylcholine in the synaptic space resulting is loss of muscle activation and function.
Local injections with botulinum toxins are currently used in humans for the treatment of disorders that benefit from prolonged neuromuscular blockade such as strabismus, blepharospasm, focal dystonias, spasticity, tremors, and anal fissures. Injections with botulinum toxin type A into the internal or external anal sphincter cause relaxation of the anal canal and allow healing of chronic anal fissures.
Perineal lacerations in mares, which occur during foaling often dehisce after surgical repair due to the high pressure across the incision resulting from accumulation of feces in the rectum. We hypothesized local injections of Clostridium botulinum type B toxin into the external anal sphincter could cause a decrease in anal pressures, thus reducing the incidence of dehiscence if used before surgical repair of perineal laceration in mares.
The purpose of this project was to determine the effects of BTB injection in the external anal sphincter in normal horses. Our hypothesis was that local injection of BTB would result in transient reduction of anal tone without causing clinical side effects. Peak and resting anal sphincter pressures of horses were measured with a custom made rectal probe connected to a pressure transducer. Pressures were measured before treatment and after injection with Clostridium botulinum type B toxin (BTB) or saline. Dose titration with 500, 1000, 1500 and 2500 units of BTB was completed. The horses' physical changes, behavior, and anal pressure were recorded. Injection of 1000 units of BTB produced significant reduction in peak anal pressure from days 2 to 84 when compared to control animals (P<0.05). Maximal effect of the toxin was observed within the first 15 days after injections followed by a slow return to baseline over 168 days. Injection in the anal sphincter with 2500 units of BTB in one horse produced signs of depression, generalized weakness, and dysphagia for 14 days. Clinical side effects were not observed in horses after injections with 500, 1000, or 1500 units of BTB.
In summary, local injections of botulinum toxin type-B in the external anal sphincter of horses caused transient relaxation of the anus and reduction of peak anal pressures. Systemic side effects were observed in one horse, which suggested a narrow dosage range to avoid toxicity. Further research to test the effects of botulinum toxin in clinical cases is needed to determine the full potential of this treatment modality.Master of Science

Full textAbstract:
A mode of pulse biasing of DLC coating deposition is theoretically investigated. In this mode a deposited
ion flow of plasma with energy of E0 (20 200) eV is modified by superimposing of pulse potential
~ 1000 V. It was shown that intrinsic stress in a DLC coating can be decreased in several times without of
essential decrease of sp3-bonded carbon concentration compared with DLC made in stationary mode deposition
at E0 ion energy. A method of optimization of pulse mode parameters is proposed which is based on
analysis of location of thermoelastic peaks of ions on phase P, T-diagram of carbon.

Full textAbstract:
AbstractFlood control concept at watershed scale is used as an adaptation strategy for climate change; rainwater and floodwater should be stored in forests and agricultural lands in the watershed, rather than relying on only river systems; and paddy fields are important ecosystems for floodwater retention. The abandonment of paddy cultivation, however, is increasing year after year in Japan due to depopulation in rural regions. Through two-dimensional numerical inundation analysis, we evaluated the negative effects of topographical changes after abandonment on the floodwater retention function. The bipolarization of the inundation depth is apparent in the current topography. The areas with deepwater inundation are wider, particularly in the most downstream areas, whereas in the past, areas with shallow water were widely distributed. The peak water level in the current land use is 0.4 m higher than in the past. After the peak level is achieved, the water level decreases in a shorter time in the present land use than in the past. Owing to hydraulic changes after the abandonment of rice cultivation, the risk of flooding disasters for people living downstream has increased. To maintain floodwater retention function, one of the regulating services, by artificial wetlands, such as paddy fields, continuous management is essential to prevent vegetation succession. Thus, it is important to provide incentives for local people to perform the daily maintenance activities.

AbstractThe need to characterise in-service damage in composite structures is increasingly becoming important as composites find higher utilisation in wind turbines, aerospace, automotive, marine, among others. This paper investigates the feasibility of simplifying the conventional acousto-ultrasonic technique set-up for quick and economic one-sided in-service inspection of composite structures. Acousto-ultrasonic technique refers to the approach of using ultrasonic transducer for local excitation while sensing the material response with an acoustic emission sensor. However, this involves transducers with several auxiliaries. The approach proposed herewith, referred to as vibro-acoustic testing, involves a low level of vibration impact excitation and acoustic emission sensing for damage characterisation. To test the robustness of this approach, first, a quasi-static test was carried out to impute low-velocity impact damage on three groups of test samples with different ply stacking sequences. Next, the vibro-acoustic testing was performed on all test samples with the acoustic emission response for the samples acquired. Using the acoustic emission test sample response for all groups, the stress wave factor was determined using the peak voltage stress wave factor method. The stress wave factor results showed an inverse correlation between the level of impact damage and stress wave factor across all the test sample groups. This corresponds with what has been reported in literature for acousto-ultrasonic technique; thus demonstrating the robustness of the proposed vibro-acoustic set-up.

Full textAbstract:
AbstractThe human species is biologically distinguished by low fertility. In fact, with each menstrual cycle, a couple at the peak of their reproductive capacity has only about a 30% chance of conceiving. The WHO states infertility as “a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected intercourse.”Assisted reproductive technology (ART) consists of all treatments or procedures that include the in vitro handling of both human oocytes and sperm or of embryos, for the purpose of establishing a pregnancy.The techniques are usually divided into three broad categories: First level techniques: Intrauterine and Intracervical Insemination (IUI/ICI), the simpler and less invasive ones, such as intrauterine insemination (IUI) with or without Intracervical Insemination (ICI) ovarian stimulation. Second level techniques: the more complex and more invasive ones that can be performed under local anesthesia or deep sedation, which differ from the basic techniques as they involve manipulation of female and male gametes and because they require in vitro fertilization. Among these techniques the IVF (In Vitro Fertilization and Embryo Transfer), ICSI (Intracytoplasmic Sperm Injection), and the possible cryopreservation of male and female gametes and embryos. Third level techniques procedures that require general anesthesia with intubation, including: laparoscopic egg retrieval, intra-tubal transfer of male and female gametes (GIFT), zygotes (ZIFT) and /or embryos (TET) laparoscopically; microsurgical sampling of gametes from the testicle: Testicular Sperm Extraction (TESE), Microsurgical Testicular Sperm Extraction (microTESE), Testicular Sperm Aspiration (TESA); microsurgical sampling of gametes from the epididymides: Percutaneous Epididymal Sperm Aspiration (PESA) and Microsurgical Epididymal Sperm Aspiration (MESA). In all assisted reproduction techniques, the seminal fluid receives a treatment able to induce capacitation “in vitro” so that the activated spermatozoa, at the threshold of the acrosomal reaction, can interact with the mature oocytes. Preimplantation Genetic Screening (PGS) and Preimplantation Genetic Diagnosis (PGD) are highly specialized procedures which involve removing three to four cells from a 5–6 day old blastocyst and testing them for chromosomal abnormalities prior to transferring the embryo into a woman’s uterus. According to data reported from the European IVF-Monitoring Consortium (EIM) for the European Society of Human Reproduction and Embryology (ESHRE), the clinical pregnancy rates (PR) per aspiration and per transfer are 28.0% and 34.8%, respectively. After ICSI, the corresponding rates are 24% and 33.5%. ART can alleviate the burden of infertility on individuals and families, but it can also present challenges to public health as evidenced by the high rates of multiple delivery, preterm delivery, and low birth-weight delivery experienced with ART.

Full textAbstract:
Alternative stress evaluation criteria suitable for Finite Element Analysis (FEA) proposed by Okamoto et al. [1],[2] have been studied by the Committee on Three Dimensional Finite Element Stress Evaluation (C-TDF) in Japan. Thermal stress ratchet criteria in plastic FEA are now under consideration. Two criteria are proposed: (1) Evaluating variations in plastic strain increments, and (2) Evaluating the width of the area in which Mises equivalent stress exceeds 3Sm. To verify of these criteria, we selected notched cylindrical vessel models as prime elements. To evaluate the effect of the local peak stress distribution on these criteria, cylindrical vessels with a semicircular notch on the outer surface were selected for this analysis. We used two notch configurations for our analysis, and the stress concentration factor for the notches was set to 1.5 and 2.0. We conducted elastic-plastic analysis to evaluate the ratchet limit. Sustained pressure and alternating enforced longitudinal displacements which causes secondary stress were used as parameters for the elastic-plastic analysis. We found that when no ratchet was observed, the equivalent plastic strain increments decreased and the area in which Mises equivalent stress exceeds 3Sm are below the certain range.

Full textAbstract:
Debntures Incentivadas or incentivized bonds are securities first issued in 2012 whose interest and capital gains enjoy income tax exemption conditional on using funds to finance infrastructure expenditures. They have a minimum duration at issuance of four years, are denominated in reais and traded in local markets under national jurisdiction. In US dollar terms, the value of bonds issued reached a peak of $9.5 billion in 2019, and the overall number of bonds since inception of the program exceeds 400. The amount of infrastructure bonds issued every year rivals BNDES loans in terms of the total amounts of financing of infrastructure projects. The Brazilian experience with creating a market for incentivized bonds can be useful to other countries in the region seeking to develop long-term financing markets in local currency to finance infrastructure.

Full textAbstract:
Political economy analysis (PEA) has emerged as a valuable approach for assessing context and the local systems where international development actors seek to intervene. PEA approaches and tools have grown and adapted over the last 40 years through innovations by donor agencies and practitioners. Our analysis of nine PEAs reveals the following findings: PEAs can make positive contributions to technical interventions; engaging project staff in PEAs increases the likelihood that they will be open to a thinking and working politically mindset and approach; inclusion of gender equity and social inclusion (GESI) in PEAs helps to uncover and address hidden power dynamics; and explicitly connecting PEA findings to project implementation facilitates adaptive management. Implementation lessons learned include careful consideration of logistics, timing, and team members. Our experience and research suggest applied PEAs provide valuable evidence for strengthening evidence-based, adaptive, international development programming. The findings highlight the promise of PEA as well as the need for ongoing learning and research to address continued challenges.

Full textAbstract:
CONTEXT: Social Licence to Operate (SLO) encompasses the broad socio-political understanding on the part of multiple stakeholders that a mining operation’s social and environmental impacts and measures are legitimate and acceptable. The multiple and variously interacting stakeholder groups— local communities, environmental actors, Indigenous communities, regulators, local governments, industry peak bodies, financiers, affiliated businesses—have the proven capacity to confer and/or disrupt a mining operation’s SLO. The presence or absence of a SLO can have significant consequences not only for stakeholder groups, including the mining operation, but also for the shared development of a good mining future. Conceptualisation of what is ‘good mining’ is central to future planning and decisions around development, adoption and reception of new technologies and sustainable mining futures. CHECKLIST PURPOSE This first of its kind tool seeks to facilitate genuine multistakeholder interactions and development of a dynamic shared SLO to advance good mining.

Full textAbstract:
Coffs Harbour on the north coast of NSW is a highway city sandwiched between the Great Dividing Range and the Pacific Ocean. For thousands of years it was the traditional land of the numerous Gumbaynggirr peoples. Tourism now appears to be the major industry, supplanting agriculture and timber getting, while a large service sector has grown up around a sizable retirement community. It is major holiday destination. Located further away from the coast in the midst of a dairy farming community, Bellingen has become a centre of alternative culture which relies heavily on a variety of festivals activated by energetic tree changers and numerous professionals who have relocated from Sydney. Both communities rely on the visitor economy and there have been considerable changes to how local government in this region approach strategic planning for arts and culture. The newly built Coffs Harbour Education Campus (CHEC) is an experiment in encouraging cross pollination between innovative businesses and education and incorporates TAFE NSW, Coffs Harbour Senior College and Southern Cross University as well as the Coffs Harbour Technology Park and Coffs Harbour Innovation Centre all on one site. The 250 seat Jetty Memorial Theatre is the main theatre in Coffs Harbour for local and touring productions while local halls and converted theatres are the mainstay of smaller communities in the region. As peak body Arts Mid North Coast reports, there is a good record of successful arts related events which range across all genres of music, art, sculpture, Aboriginal culture, street art, literature and even busking and opera. These are mainly managed by passionate local volunteers.

Full textAbstract:
We developed methods for examining the pathophysical response of striped bass and hybrid bass to various forms of stress. This involved development of techniques for the measurement of lysozyme, mitogen blastogenesis, mixed lymphocyte reaction, and oxidative burst, which are important general indicators of systemic immune function. We also examined local immune defenses (epithelial integrity), as well as homeostatic indicators in blood, including osmotic balance and glucose. Acute stress resulted in significant perturbations in a number of parameters, including glucose, electrolytes, osmolarity, lysozyme, and mixed lymphocyte reaction. Most significantly, acute confinement stress resulted in severe damage to the epidermal epithelium, as indicated by the rapid (within 2 hr) development of erosions and ulcerations on various fins. There were significant differences in the resting levels of some immune functions between striped bass and hybrid bass, including response to mitogens in the leukocyte blastogenesis test. Our studies also revealed that there were significant differences in how striped bass and hybrid bass respond to stress, with striped bass being much more severely affected by stress than the hybrid. This was reflected in more severe changes in glucose, cortisol dynamics, and plasma lysozyme. Most significantly, striped bass developed more severe idiopathic skin ulceration after stress, which may be a major reason why this fish is so prone to develop opportunistic bacterial and fungal infections after stress. Hybrid bass injected with equine serum albumin developed a typical humoral immune response, with peak antibody production 28 days after primary immunization. Fish that were exposed to a chronic stress after a primary immunization showed almost complete inhibition of antibody production.

Herbert, Siân. Donor Support to Electoral Cycles. Institute of Development Studies (IDS), April 2021. http://dx.doi.org/10.19088/k4d.2021.043.
Full textAbstract:
This rapid literature review explains the stages of an election cycle, and how donors provide support to electoral cycles. It draws mainly on policy guidance websites and papers due to the questions of this review and the level of analysis taken (global-level, donor-level). It focuses on publications from the last five years, and/or current/forthcoming donor strategies. The electoral cycle and its stages are well-established policy concepts for which there is widespread acceptance and use. Donor support to electoral cycles (through electoral assistance and electoral observation) is extremely widespread, and the dominant donors in this area are the multilateral organisations like the United Nations (UN) and the European Union (EU), and also the United States (US). While almost all bilateral donors also carry out some work in this area, “almost all major electoral support programmes are provided jointly with international partners” (DFID, 2014, p.5). Bilateral donors may provide broader support to democratic governance initiatives, which may not be framed as electoral assistance, but may contribute to the wider enabling environment. All of the donors reviewed in this query emphasise that their programmes are designed according to the local context and needs, and thus, beyond the big actors - EU, UN and US, there is little overarching information on what the donors do in this area. While there is a significant literature base in the broad area of electoral support, it tends to be focussed at the country, programme, or thematic, level, rather than at the global, or donor, level taken by this paper. There was a peak in global-level publications on this subject around 2006, the year the electoral cycle model was published by the European Commission, International Institute for Democracy and Electoral Assistance (International IDEA), and United Nations Development Programme (UNDP). This review concludes by providing examples of the electoral assistance work carried out by five donors (UN, EU, US, UK and Germany).

Mineta Transportation Institute, January 2023. http://dx.doi.org/10.31979/mti.2023.2153.
Full textAbstract:
Permanent capacity expansion, such as adding new lanes, is no longer a viable strategy to address traffic congestion in California; hence, ITS (Intelligent Transportation System) strategies, such as part-time use of the shoulder as a travel lane, need to be explored. The use of the shoulder as a travel lane during peak traffic hours has limited applications in the US, and most use the right shoulder as a part-time travel lane even though either the right or left shoulder (but not both) may be used. Caltrans District 5 is exploring the use of Left Shoulder as a Part-time Travel Lane (LSPTTL) as a piece of the larger project, titled Five Cities Multimodal Transportation Network Enhancement Project (FCMTNEP), aimed at congestion relief near Pismo Beach, CA. Construction is expected to begin in Winter 2025 with a Winter 2027 completion date. Given that this would be the first instance of LSPTTL in California, it is a Project of Division Interest (PoDI) for the California division of Federal Highway Administration (FHWA), and the District 5 experience may guide similar future installations of the shoulder as travel lane projects in the state. This research uses a microsimulation-based approach to evaluate design alternatives being explored by Caltrans District 5. This approach allows for evaluating the operational and safety effects of each of the alternatives. Furthermore, a Transportation Management Center (TMC) operator training framework has also been developed to ensure that the local TMC personnel can effectively deploy the LSPTTL during routine operations and emergencies. Based on the operational evaluation, the study found no significant difference in travel times associated with the three design alternatives. Alternative 2, which involves the longest segment with LSPTTL among the alternatives, was found to be the safest based on a surrogate safety measure-based evaluation. This framework for evaluating design alternatives for operations and safety effectiveness may be used for future projects that involve the use of the shoulder as a travel lane. For TMC operator training, this report documents key learning objectives. A hands-on training program that involves operators executing the opening and closing of the shoulder for routine and emergency conditions was developed. As the project nears implementation, there is some scope for improvement in the training modules through replication of the exact features of the LSPTTL design and introducing more realism in the TMC simulator training exercises.

Five parks were added to the reporting system in 2021: Alagnak Wild River in Alaska, Camp Nelson National Monument in Kentucky, Medgar and Myrlie Evers Home National Monument in Mississippi, Tule Springs Fossil Beds National Monument in Nevada, and World War I Memorial in Washington, D.C. These parks were responsible for over 629,000 recreation visits in 2021. Factors influencing visits to National Park System units in 2021 include: continuing closures and limited capacities due to COVID-19 mitigation at some parks, temporary closures for wildland fires in 2021 (eleven parks), severe regional smoke/haze from ongoing wildland fires throughout the summer and early autumn affecting parks in the western half and northern tier of states in the continental U.S., two hurricanes in 2021 – both in August – impacted visitation: Hurricane Henri caused temporary closures of some parks in the northeast and Hurricane Ida caused temporary closures of parks along the Gulf Coast and generated some heavy flooding in the northeast, hurricanes and wildland fires in previous years resulting in lingering closures, most notably Hurricanes Irma and Maria in 2017, the Carr and Woolsey Fires in 2018, Hurricane Dorian in 2019, the Caldwell, Cameron Peak, East Troublesome, and Woodward Fires in 2020, and Hurricane Sally in 2020. Forty-four parks set a record for recreation visits in 2021 and 6 parks broke a record they set in 2020. See Appendix A for a list of record parks. The number of reporting units with over 10 million recreation visits was the same as in recent years (3 parks) and 73 parks had over 1 million recreation visits. Twenty-five percent of total recreation visits occurred in the top 8 parks and fifty percent of total visitation occurred in the top 25 parks. Several parks passed annual visitation milestones including Capulin Volcano NM which passed 100,000 annual recreation visits for the first time, Big Bend NP and Devils Tower NM which each passed 500,000 annual recreation visits for the first time, and Zion NP which passed 5 million visits for the first time. Other parks passed milestones for accumulated recreation visits including Hamilton Grange NMEM (1968-2021) and Palo Alto Battlefield NHP (2003-2021) each passing 1 million total recreation visits, Voyageurs NP (1976-2021) passing 10 million total recreation visits, and Hot Springs NP (1904-2021) passing 100 million total recreation visits. Population center designations were updated in 2021 to reflect overlap of park boundaries with statistical areas from the 2020 U.S. Census. Many population center changes reflect increases in local population as indicated by parks changing from rural to outlying or from outlying to suburban. Other changes reflect increasing complexity in population density as parks changed from a single designation, such as rural or suburban, to a mixed designation. See the Definitions section for population center definitions and Table B.1 for previous and updated population center designations by park. In the pages that follow, a series of tables and figures display visitor use data for calendar year 2021. By documenting these visits across the National Park System, the NPS Statistical Abstract offers a historical record of visitor use in parks and provides NPS staff and partners with a useful tool for effective management and planning. In 2021, 394 of 423 NPS units...

Full textAbstract:
Emergency Relief (ER) is a Department of Social Services (DSS) funded program, delivered by 197 community organisations (ER Providers) across Australia, to assist people facing a financial crisis with financial/material aid and referrals to other support programs. ER has been playing this important role in Australian communities since 1979. Without ER, more people living in Australia who experience a financial crisis might face further harm such as crippling debt or homelessness. The Emergency Relief National Coordination Group (NCG) was established in April 2020 at the start of the COVID-19 pandemic to advise the Minister for Families and Social Services on the implementation of ER. To inform its advice to the Minister, the NCG partnered with the Institute for Governance at the University of Canberra to conduct research to understand the issues and challenges faced by ER Providers and Service Users in local contexts across Australia. The research involved a desktop review of the existing literature on ER service provision, a large survey which all Commonwealth ER Providers were invited to participate in (and 122 responses were received), interviews with a purposive sample of 18 ER Providers, and the development of a program logic and theory of change for the Commonwealth ER program to assess progress. The surveys and interviews focussed on ER Provider perceptions of the strengths, weaknesses, future challenges, and areas of improvement for current ER provision. The trend of increasing case complexity, the effectiveness of ER service delivery models in achieving outcomes for Service Users, and the significance of volunteering in the sector were investigated. Separately, an evaluation of the performance of the NCG was conducted and a summary of the evaluation is provided as an appendix to this report. Several themes emerged from the review of the existing literature such as service delivery shortcomings in dealing with case complexity, the effectiveness of case management, and repeat requests for service. Interviews with ER workers and Service Users found that an uplift in workforce capability was required to deal with increasing case complexity, leading to recommendations for more training and service standards. Several service evaluations found that ER delivered with case management led to high Service User satisfaction, played an integral role in transforming the lives of people with complex needs, and lowered repeat requests for service. A large longitudinal quantitative study revealed that more time spent with participants substantially decreased the number of repeat requests for service; and, given that repeat requests for service can be an indicator of entrenched poverty, not accessing further services is likely to suggest improvement. The interviews identified the main strengths of ER to be the rapid response and flexible use of funds to stabilise crisis situations and connect people to other supports through strong local networks. Service Users trusted the system because of these strengths, and ER was often an access point to holistic support. There were three main weaknesses identified. First, funding contracts were too short and did not cover the full costs of the program—in particular, case management for complex cases. Second, many Service Users were dependent on ER which was inconsistent with the definition and intent of the program. Third, there was inconsistency in the level of service received by Service Users in different geographic locations. These weaknesses can be improved upon with a joined-up approach featuring co-design and collaborative governance, leading to the successful commissioning of social services. The survey confirmed that volunteers were significant for ER, making up 92% of all workers and 51% of all hours worked in respondent ER programs. Of the 122 respondents, volunteers amounted to 554 full-time equivalents, a contribution valued at $39.4 million. In total there were 8,316 volunteers working in the 122 respondent ER programs. The sector can support and upskill these volunteers (and employees in addition) by developing scalable training solutions such as online training modules, updating ER service standards, and engaging in collaborative learning arrangements where large and small ER Providers share resources. More engagement with peak bodies such as Volunteering Australia might also assist the sector to improve the focus on volunteer engagement. Integrated services achieve better outcomes for complex ER cases—97% of survey respondents either agreed or strongly agreed this was the case. The research identified the dimensions of service integration most relevant to ER Providers to be case management, referrals, the breadth of services offered internally, co-location with interrelated service providers, an established network of support, workforce capability, and Service User engagement. Providers can individually focus on increasing the level of service integration for their ER program to improve their ability to deal with complex cases, which are clearly on the rise. At the system level, a more joined-up approach can also improve service integration across Australia. The key dimensions of this finding are discussed next in more detail. Case management is key for achieving Service User outcomes for complex cases—89% of survey respondents either agreed or strongly agreed this was the case. Interviewees most frequently said they would provide more case management if they could change their service model. Case management allows for more time spent with the Service User, follow up with referral partners, and a higher level of expertise in service delivery to support complex cases. Of course, it is a costly model and not currently funded for all Service Users through ER. Where case management is not available as part of ER, it might be available through a related service that is part of a network of support. Where possible, ER Providers should facilitate access to case management for Service Users who would benefit. At a system level, ER models with a greater component of case management could be implemented as test cases. Referral systems are also key for achieving Service User outcomes, which is reflected in the ER Program Logic presented on page 31. The survey and interview data show that referrals within an integrated service (internal) or in a service hub (co-located) are most effective. Where this is not possible, warm referrals within a trusted network of support are more effective than cold referrals leading to higher take-up and beneficial Service User outcomes. However, cold referrals are most common, pointing to a weakness in ER referral systems. This is because ER Providers do not operate or co-locate with interrelated services in many cases, nor do they have the case management capacity to provide warm referrals in many other cases. For mental illness support, which interviewees identified as one of the most difficult issues to deal with, ER Providers offer an integrated service only 23% of the time, warm referrals 34% of the time, and cold referrals 43% of the time. A focus on referral systems at the individual ER Provider level, and system level through a joined-up approach, might lead to better outcomes for Service Users. The program logic and theory of change for ER have been documented with input from the research findings and included in Section 4.3 on page 31. These show that ER helps people facing a financial crisis to meet their immediate needs, avoid further harm, and access a path to recovery. The research demonstrates that ER is fundamental to supporting vulnerable people in Australia and should therefore continue to be funded by government.
