Boom And Bust Cycles

The Pilbara region in Australia’s arid northwest is rich in flora that is suited to extreme temperatures and boom and bust cycles of moisture availability. It is also a region important for its natural resources. In places where mining activities have finished and the land is under management for ecological restoration, there is increasing demand for information about native plant communities and the biology of their seeds. Pilbara Seed Atlas and Field Guide is the first book to combine plant identification with robust, scientific criteria for cost-effective seed-based rehabilitation. It describes 103 regional plant taxa and provides guidelines for effective collection, cleaning, storage and germination of their seeds. It addresses issues such as timing of collection, quality and viability of seed, and dormancy release, which are essential for successful restoration programs. With photographs to portray the subtle differences and unique features of each species’ biology, this book will be of great use to practitioners in the field, including environmental consultants, rehabilitation companies, commercial seed collectors and government authorities, as well as naturalists and people interested in growing the Pilbara’s remarkable plants.

Boom And Bust Cycles

Pakistan has seen strong economic growth in recent years accompanied by a reduction in poverty. However, growth has been concentrated, which has meant that regional and inter-personal disparities are on the rise. In a contestable political environment, this casts a shadow on the sustainability of high growth. The budget, a corrective instrument, has been subject to boom and bust cycles because of rigid claims, poor tax effort and external shocks, rendering it ineffective in addressing long term priorities. This paper argues that robust budgets for sustained and inclusive growth require government programs to be credible (monitoring and evaluation and public information) and cost effective (streamlined budget cycle, public-private partnerships); this will help increase citizen willingness to pay for public programs via improved tax compliance.

Austerity Policy

Is macroeconomic stability the Achilles heel of the Chinese economy? Recurrent bouts of inflationary disorder lead some observers to worry that the Chinese government is unable to control the economy. Macroeconomic difficulties show up in a pattern of repeated boom and bust cycles, in which each boom is accompanied by an acute inflationary phase and significant disruption. Moreover, since the reform era began, the peak annual inflation rate of each successive cycle has been higher than that of the preceding one. The most recent attempts to cool off the economy have only led to additional questions. An austerity policy was decreed at the end of June 1993, yet inflation actually accelerated in 1994, and it was not until mid-1995 that it dropped to the levels of mid-1993. The Chinese government was engaged in a quest for an economic “soft landing” for two years without a net reduction in the inflation rate!

Increasing Demand

The increasing demand for high precision indoor positioning in many public services has urged research to implement cost-effective systems for a rising number of applications. However, current systems with either short-range positioning technology based on wireless local area networks (WLAN) and ZigBee achieving meter-level accuracy, or ultra-wide band (UWB) and 60 GHz communication technology achieving high precision but with high cost required, could not meet the need of indoor wireless positioning. This paper presents a new method of high precision indoor positioning by autocorrelation phase measurement of spread spectrum signal utilizing carrier frequency lower than 1 GHz, thereby decreasing power emission and hardware cost. The phase measurement is more sensitive to the distance of microwave transmission than timing, thus achieving higher positioning accuracy. Simulation results demonstrate that the proposed positioning method can achieve high precision of less than 1 centimeter decreasing when various noise and interference added.

Abstract Mining is one of the main pollution issues worldwide, causing the greatest disturbances to the environment. Industrial and artisanal mining activities are widespread in Mexico, being a major global producer of various metals. This study aimed to assess the ecological impairments resulting from mining activities using the aquatic macroinvertebrates assemblages (MA). A multiple co-inertia analysis (MCOA) was applied to determine the relationships between environmental factors, habitat quality, heavy metals, and aquatic macroinvertebrates in two rivers of the Central Plateau, Mexico. The results revealed three contrasting environmental conditions and different MA. High concentrations of heavy metals, nutrients, and salinity limit the presence of various families of seemingly sensitive macroinvertebrates, these factors were identified as the drivers of structural changes in the MA, showing that not only mining activities, but also agriculture, and villages in the basin, exert negative effects to the macroinvertebrate communities. Diversity indices showed that the lowest diversity matched with both, the most polluted and the most saline rivers. The rivers studied displayed a high alkalinity and hardness, which can lead to the formation of metal precipitates and thus acting as a protection to aquatic biota. Aquatic biomonitoring in rivers, impacted by mining and other human activities, is critical for detecting the effect of metals and other pollutants to improve management and conservation strategies. This study supports the design of cost-effective and accurate water quality biomonitoring protocols in developing countries.

Arid plant communities provide variable diets that can affect digestive microbial communities of free-foraging ruminants. Thus, we used next-generation sequencing of 16S and 18S rDNA to characterize microbial communities in the rumen (regurgitated digesta) and large intestine (faeces) and diet composition of lactating creole goats from five flocks grazing in native plant communities in the Sonoran Desert in the rainy season. The bacterial communities in the rumen and large intestine of the five flocks had similar alpha diversity (Chao1, Shannon, and Simpson indices). However, bacterial community compositions were different: a bacterial community dominated by Proteobacteria in the rumen transitioned to a community dominated by Firmicutes in the large intestine. Bacterial communities of rumen were similar across flocks; similarly occurred with large-intestine communities. Archaea had a minimum presence in the goat digestive tract. We detected phylum Basidiomycota, Ascomycota, and Apicomplexa as the main fungi and protozoa. Analyses suggested different diet compositions; forbs and grasses composed the bulk of plants in the rumen and forbs and shrubs in faeces. Therefore, lactating goats consuming different diets in the Sonoran Desert in the rainy season share a similar core bacterial community in the rumen and another in the large intestine and present low archaeal communities.

Abstract Objectives The increasing demand for herbal drugs for the human application is causing a growing demand for the cultivation of Medicinal Plants. This demand has developed because of cost-effective, plant-derived products rather than commercially available synthetic drugs. Cucumis sativus Linn. (Ver. Kheera) is a vegetable climber, species belongs to family Cucurbitaceae This species has a wide range of medicinal and biological applications thanks to its richness in carbohydrate, proteins, minerals (calcium, iron, magnesium, phosphorus, potassium, zinc) and secondary metabolites like alkaloids, tannins, flavonoids, saponins, and phenolic compounds These phytoconstituents may be responsible for allied therapeutic application. So, C. sativus possess wider applications for preventing certain ailments. Content The literature in various national and international journals and reports pertaining to the medicinal and nutritional uses were reviewed. The result revealed the current therapeutic applications of C. sativus whole plants other than the nutritional value. C. sativus pharmacological action includes antioxidant, anti-diabetic, UV protectant, hepatoprotective, gastroprotective, anti-helminthic, wound healing, antimicrobial, and anticancer. So, it could be useful for both preventive and additive therapy along with modern medicine for the better management of certain disorders. Summary and Outlook This review furnishes updated information about the phytoconstituents and their medicinal applications so that it can pose a path for the young researchers to do future findings.

Boom And Bust Cycles

Due to the continued high price of oil and gas, the oil-rich State of Qatar has used its large budget surpluses in the last decade to finance human capacity development, including research, higher education, and the reshaping of its K-12 educational system. This chapter argues that the recent substantial educational reforms in the State of Qatar are closely intertwined with planned future economic transformation (diversification). Although Qatar possesses the world's third largest reserves of natural gas, this resource is ultimately finite and over-reliance on one major economic driver (hydrocarbons) for the bulk of GDP creates boom and bust cycles that have shaped Gulf politics and social development since the 1970s. This chapter examines Qatar's educational efforts to build a knowledge economy to transition away from a resource-rich export-based hydrocarbon economy towards economic activities linked to patents, research, trademarked technologies, skills, and knowledge products.
