Despite the Realist’s assertion that nothing fundamental changes in world politics, change is the norm in all life and all fields. World politics is no exception. Yes, there are continuities in world politics; they are the persistent, albeit themselves changing, mechanisms that foster fundamental change, the both large and small alterations in the nature of agents, structures, processes, and the content of arguments. Sometimes things change slowly, they evolve. And sometimes radical changes occur in a relatively short period of time; we might think of the latter as phase changes or radical ruptures at tipping points. But often those ruptures have been preceded by decades of slower work by advocates of change toiling in civil societies or specialized communities. Thus, a great deal of effort goes into not only making change but also resisting change.

We present the results of six years of archaeological work carried out in Heping Dao, Keelung, northern Taiwan. The site has revealed a rich archaeological record spanning a sequence that comprehends most of the history of Taiwan, including the most salient historical landmarks in it. The study of this long-term sequence of habitation in Heping Dao throughout prehistory to current times, allows us to attempt a historical archaeology of the longue duree of the place that in turn enables the establishment of comparisons between periods and raising of specific questions, among them: the general understanding of cultural transformation along the Neolithic and the Iron Age, and in turn the transition Iron Age/Aboriginal historic times in Taiwan, which in our view has to be observed as a history of continuity rather than of interactions; the recognition of the Chinese presence in Taiwan in the pre-European period; the implantation of the European colony and its effects on the local populations; the differing material remains and impacts caused by the presence of preEuropean Chinese and the Qing occupation; and the potential for a comparison between the European and the Japanese colonial projects as seen in the material record.

Less than 2% of Malawian women use long-acting reversible contraception (LARC). We describe experiences of Malawian family planning providers, focusing on LARC. We conducted a mixed-methods study using questionnaires and focus group discussions with providers in Lilongwe. Data were analyzed separately and triangulated. Most (58%) participants saw over 30 patients daily. Only 19% had ever inserted IUC. Qualitative data were complementary; participants noted that LARC provision was important, though hindered by lack of experienced providers, work burden, and low demand. Future efforts to improve LARC access in Lilongwe must address both supply and demand-side barriers. Moins de 2% des femmes malawiennes utilisent la contraception de longue durée d'action réversible (CLDR). Nous décrivons les expériences des prestataires de planification familiale malawienne, en nous concentrant sur CLDR. Nous avons effectué une étude des méthodes mixtes ? l'aide des questionnaires et des discussions de groupes cibles avec les fournisseurs ? Lilongwe. Les données ont été analysées séparément et ont été triangulées. La plupart (58%) des participants ont vu plus de 30 patientes par jour. Seulement 19% avaient déj? inséré DIU. Les données qualitatives etaient complémentaires; les participants ont noté que la provision de la CLDR était importante, quoique entravée par le manque de fournisseurs expérimentés, la charge de travail, et la faible demande. Les futurs efforts pour améliorer l'accès ? la CLDR ? Lilongwe doit s'occuper des deux barrières de coté de l'offre et de la demande.

Despite striking differences in climate, soils, and evolutionary history among diverse biomes ranging from tropical and temperate forests to alpine tundra and desert, we found similar interspecific relationships among leaf structure and function and plant growth in all biomes. Our results thus demonstrate convergent evolution and global generality in plant functioning, despite the enormous diversity of plant species and biomes. For 280 plant species from two global data sets, we found that potential carbon gain (photosynthesis) and carbon loss (respiration) increase in similar proportion with decreasing leaf life-span, increasing leaf nitrogen concentration, and increasing leaf surface area-to-mass ratio. Productivity of individual plants and of leaves in vegetation canopies also changes in constant proportion to leaf life-span and surface area-to-mass ratio. These global plant functional relationships have significant implications for global scale modeling of vegetation-atmosphere CO2 exchange

The influence of the solvent, temperature, and extraction time on the extractability of total polyphenols from milled soybeans (variety Ika) was investigated. The study was performed in order to select the most suitable solvent (water; 50, 60, 70, and 80% aqueous ethanol) for achieving the highest yield of total polyphenols. The most effective solvent (50% aqueous ethanol solution) was used for monitoring the kinetics and modelling of solid-liquid extraction of total polyphenols from soybeans, average particle size 0.459 mm, at solid-liquid ratio of 20 mL/g (ratio of the solvent volume per g of raw material). The total polyphenols content in the soybean extract was determined spectrophotometrically using Folin-Ciocalteu micro-methods at 765 nm. The applicability of different mathematical models (Peleg, Page, and Logarithmic models) to describe the kinetics of the solid-liquid extraction process of total polyphenols from soybeans was studied as well. The results exhibited a significant influence of the solvent and temperature on the kinetics and extraction yield of total polyphenols from soybeans. The best extraction yield of total polyphenols was obtained using 50% aqueous ethanol solution at 80 deg C after 120 min (4.322 mg GAE/gdb). The extraction yield of total polyphenols in soybean extracts increased by increasing the extraction temperature and extending the duration of the extraction process. The mathematical models applied showed a good agreement with the experimental results, which allows their application in modelling and optimisation of solid-liquid extraction process for the extraction of total polyphenols from soybeans.

Coined in the third century B.C., the term diaspora has evolved into a buzzword used to describe the migrations of groups as diverse as ethnic populations, religious communities, and even engineers working abroad. This concise book provides a critical introduction to the concept of diaspora, bringing a fresh, synthetic perspective to virtually all aspects of this topic. Stéphane Dufoix incorporates a wealth of case studies—about the Jewish, Armenian, African, Chinese, Greek, and Indian experiences— to illustrate key concepts, give a clear overview on current thinking, and reassess the value of the term for us today.

The World of Protracted Conflicts seeks to frame the models to answer three crucial questions about interstate protracted conflict: what are the most likely conditions for the onset of a protracted conflict, its escalation/persistence, and its termination? It presents the findings on protracted conflict occurrence, continuation, and resolution through testing these models and their derived hypotheses against the evidence from 33 interstate protracted conflicts in the last century. These findings will, in turn, shed further light on the conflict-crisis-war linkage. This book examines and explains patterns that exist in the eruption, evolution, and winding down of these conflicts through a systematic comparison of recent and contemporary PCs.

Predator searching efficiency increases in response to a variety of environmental cues associated with its prey. The sugary excretion of aphids (honeydew) has been found to act as a prey-associated cue for many aphid natural enemies. In the present study, the honeydew excreted by Acyrthosiphon pisum (Harris) was identified as an arrestant and a contact kairomone for young larvae and adults of a common predatory hoverfly, Episyrphus balteatus (De Geer) (Diptera: Syrphidae). First and second instar larvae increased their foraging behaviour in the honeydew-treated area. When plants were sprayed with crude honeydew, the speed of movement of female E. balteatus was significantly higher than in controls, resulting in a longer period of time spent on treated plants and laying eggs. We conclude that the honeydew excreted by A. pisum induces searching behaviour and acts as and arrestant not only for adults but also for young E. balteatus larvae.

Almost Homeis a rich and comprehensive study of the policy questions underlying the shift in medical care from hospitals to homes and communities, a change that is reshaping Canadian health care policy and politics. Using document analysis, and interviews with government officials and other key stakeholders in the policy community, the authors analyze the policy content and process of five different attempts to reform home and community care in Ontario between 1985 and 1996, as introduced by governments from three different political parties. As this study demonstrates, the ongoing shift from the Medicare 'mainstream' of physician and hospital care to the Medicare 'margins,' entails not only a shift in the site of care but an erosion of the post-war state's role in health care. While Medicare continues to resist political and ideological forces aimed at shrinking the state's role, cost constraints, demographic pressures and technological advancements are increasing pressure on home and community care. The authors have made a significant contribution to research on policy development and change. Their rigorously analytical approach fills a major gap in book-length literature on long-term health care in Canada.

Many foods are prepared using egg white, most of them being based on the foaming properties of egg white which are due to albumen proteins ability to encapsulate and retain air. Therefore, many scientists aim to find new methods to improve the volume and the stability of egg white foam. This paper is a review of various factors affecting the foaming ability of egg white.
