Activity costs can account for a major proportion of fish energy budgets and may trade off against observed growth rates in wild fish populations. Recent approaches to estimating activity costs in situ have used a contaminantbioenergetic mass balance modelling approach, allowing for a broader examination of activity costs among populations compared with time-consuming alternative approaches. We report the results of this contaminantbioenergetic modelling approach to estimating in situ activity costs compared with two alternative independent methods of assessing in situ activity costs. Comparisons were made between a fast- and slow-growing yellow perch (Perca flavescens) population. Contaminantbioenergetic estimates of activity costs in the fast-growing population were 39% lower than those in the slow-growing population. Activity estimated from recorded swimming behaviours was 37% lower in the fast-growing population and 22%29% lower in the fast-growing population based on published relationships between activity costs and axial white muscle glycolytic enzyme capacities. Consumption rates were actually 32% lower in the fast-growing population, implying that lower activity costs more than compensated for lower food intake. The agreement among the three independent measures of activity costs strongly support the idea that activity costs, rather than food intake, are a major determinant of growth differences in these two wild fish populations.

Genetic diversity is an important aspect of a selective breeding program to produce fish broodstock carrying superior traits such as fast-growing, disease resistant, and other traits. We have carried out a breeding program to produce a fast-growing striped catfish (Pangasianodon hypophthalmus) since 2010. The aim of this study was to evaluate the genetic variation of the first (G-1) and second (G-2) generations of fast-growing striped catfish using microsatellite analysis. The G-1 and G-2 populations were selected individually from populations. DNA samples were collected from 40 ind. fish of each population and analyzed using five microsatellite loci (Pg1, Pg2, Pg3, Pg13, and Pg14). The results showed that the number of alleles per loci in the G-1 and G2 populations ranged from 4 to 7 alleles, with an average of five for each generation. The average of observed heterozygosity of the G-1 population (0.420) was lower than the G-2 population (0.495). Inbreeding level showed that the G-1 population was more inbred than the G-2 population. The study also found that both striped catfish populations had relatively low genetic variation. This result suggests that monitoring of genetic variation and better scheme of good spawning were needed on the next selection program to produce the intended fast-growing striped catfish.

Since the beginning of the 21st century, Turkmenistan’s economy has been growing very fast, which has been primarily generated through the extractive sector and construction industry. After the energy price collapse in mid-2014, the country has recorded a shortage of foreign currency. The authoritarian regime passed currency and economic problems onto the society. As a result, the country has experienced the most severe food crisis in its history.
The main aim of the paper is to identify the reasons behind the food crisis in Turkmenistan. The paper tries to answer the following question: how did it happen that people in one of the fastest-growing countries in the 21st century have been suffering from food shortages? The study is based on data retrieved from the World Bank Open Data, ILOSTAT, and Observatory of Economic Complexity, as well as a critical review of independent news websites.
The food crisis in Turkmenistan was primarily caused by hyperinflation and rationing basic groceries at preferential prices, wage arrears, cutting salaries of state employees to fund construction projects in progress, group layoffs of state employees, growing difficulties in running a private business, and depriving people of the possibility to exchange the currency at the official rate. The end of a free provision of Turkmenistan’s population with electricity, gas, and drinking water has further deepened the crisis.

Species around the world have suffered collapses, and a key question is why some populations are more vulnerable than others. Traditional conservation biology and evidence from terrestrial species suggest that slow-growing populations are most at risk, but interactions between climate variability and harvest dynamics may alter or even reverse this pattern. Here, we test this hypothesis globally. We use boosted regression trees to analyse the influences of harvesting, species traits and climate variability on the risk of collapse (decline below a fixed threshold) across 154 marine fish populations around the world. The most important factor explaining collapses was the magnitude of overfishing, while the duration of overfishing best explained long-term depletion. However, fast growth was the next most important risk factor. Fast-growing populations and those in variable environments were especially sensitive to overfishing, and the risk of collapse was more than tripled for fast-growing when compared with slow-growing species that experienced overfishing. We found little evidence that, in the absence of overfishing, climate variability or fast growth rates alone drove population collapse over the last six decades. Expanding efforts to rapidly adjust harvest pressure to account for climate-driven lows in productivity could help to avoid future collapses, particularly among fast-growing species.

The main objective of the paper is to examine the evolution of spatial patterns of settlement network in Slovakia as a result of population rearrangement among municipalities based on time series data of 1993 - 2017. The objects of the research are municipalities, which during the searched period recorded unusual fast population growth or decline, far exceeding the chosen parameter of the population sample. The primary population sample consists of 2919 municipalities. The experimental samples consist of 563 of fast-growing municipalities and 413 of fast-declining municipalities, based on the chosen statistical criteria, what is the compound annual growth rate. The results have shown that fast-growing municipalities are predominantly situated on the West, surrounding the Bratislava agglomeration, on the North and the East surrounding the Kosice metropolis. Generally, they tend to cluster around the cities on the district and regional levels. Fast-declining municipalities predominantly situated in the Middle, along the Hungarian, Polish, and Ukrainian border on the South and the East of the country, respectively.

AbstractFast-growing and slow-growing plant species are suggested to show integrated economics spectrums and the tradeoffs of fast growth are predicted to emerge as susceptibility to herbivory and resource competition. We tested if these predictions also hold for fast-growing and slow-growing genotypes within a silver birch, Betula pendula population. We exposed cloned saplings of 17 genotypes with slow, medium or fast height growth to reduced insect herbivory, using an insecticide, and to increasing resource competition, using naturally varying field plot grass cover. We measured shoot and root growth, ectomycorrhizal (EM) fungal production using ergosterol analysis and soil N transfer to leaves using 15N-labelled pulse of NH4+. We found that fast-growing genotypes grew on average 78% faster, produced 56% and 16% more leaf mass and ergosterol, and showed 78% higher leaf N uptake than slow-growing genotypes. The insecticide decreased leaf damage by 83% and increased shoot growth, leaf growth and leaf N uptake by 38%, 52% and 76%, without differences between the responses of fast-growing and slow-growing genotypes, whereas root mass decreased with increasing grass cover. Shoot and leaf growth of fast-growing genotypes decreased and EM fungal production of slow-growing genotypes increased with increasing grass cover. Our results suggest that fast growth is genotypically associated with higher allocation to EM fungi, better soil N capture and greater leaf production, and that the tradeoff of fast growth is sensitivity to competition, but not to insect herbivory. EM fungi may have a dual role: to support growth of fast-growing genotypes under low grass competition and to maintain growth of slow-growing genotypes under intensifying competition.

There is a growing demand for novel dosage forms to cater to the needs of the pediatric and geriatric population. In order to assist or satisfy these patients, several fast disintegrating drug delivery systems have been developed and marketed. However, such fast disintegrating solid preparations suffer from certain major drawbacks including fear of choking/swallowing, fragility and friability and requirement of specialized and expensive packaging.

Water shortage issues have been growing concerns in many cities around the world in recent years, especially in Eastern cities of Australia, which is the driest continent on the earth. The aim of this PhD thesis is a development of a model to study the use of waste incineration energy supplemented by alternative energy to power seawater desalination. It is to aid the freshwater supply of a drought stricken city in Eastern Australia. My work contributes to a development of efficient model in a simpler understandable way to reduce efforts required for modelling complex multi domain problems. This research is motivated by the successive severe drought conditions that affected many Australian cities in the past few years, compounded with an additional strain from a fast growing population. While we dump our waste into the Australian landscape, in more densely populated cities in Europe and Asia, the waste is incinerated to obtain thermal energy for various purposes. The waste is used as an energy source while at the same time reducing the amount of space needed for landfill. Seawater desalination has been uccessfully practiced for quite some time particularly in the Middle Eastern countries. To deal with increasing water shortage crisis, many cities around the world have opted or are considering seawater desalination to supplement their freshwater supply. The combination of both - waste incineration and seawater desalination - has rarely been studied. This is a twofold problem that requires modelling the problem of water demand and supply together with waste incineration to find a sustainable solution. This is a complex task. The effort needed for this can be reduced by using a modelling approach that is more efficient than the traditionally used statistical approaches. In this thesis, I present a comprehensive model developed using a dynamic system approach combined with artificial neural networks. It simulates water demand and supply as well as the possible amount of the desalinated water that can be produced using the energy from clean city waste incineration. This is done while taking in various influential factors including population growth and irregular weather patterns. This research comprises a literature review on seawater desalination and waste incineration, the establishment of water demand and supply dynamics of Gold Coast City as my case study and identifying any modelling difficulties that need to be overcome. This is followed by the development of a comprehensive model and its components, model calibration and simulation experiments. It was found that with the energy of waste incineration, up to 60% of the freshwater demand could be fulfilled by seawater desalination in a sustainable way.

Chapter 12 describes how, faced with a severe shortage of trained workers, the author initiated the training of tecnicos de cirurgia—assistant medical officers trained for surgery—to tackle the pressing needs of pregnant women and war casualties. This account shows that by careful recruitment, training, and consistent supervision it is possible to develop and train non-medical workers to deliver services that are only undertaken by doctors in Europe, the US, and most of the rest of the world. It covers how, almost 30 years later, the programme is still in place and serving the majority of the rural populations of Mozambique, and how the country continues to face enormous health needs but has become, in the last few years, one of the ‘frontier economies’ of sub-Saharan Africa, growing fast economically and beginning to be able to offer its young population the promise of greater opportunities and better services. It also discusses how, at the same time, other countries in Africa and beyond, faced with their own crises in how to provide healthcare for their populations, are interested in learning the lessons from Mozambique’s experiences.

Wildlife sanctuaries rescue, rehabilitate, reintroduce and provide life-long care for orphaned and injured animals. Understanding a sanctuary’s population dynamics—patterns in arrival, mortality and projected changes in population size—allows careful planning for future needs. Building on previous work on the population dynamics of chimpanzees (Pan troglodytes) in sanctuaries of the Pan African Sanctuary Alliance (PASA; Faust et al. 2011), this chapter extends analyses to the only PASA bonobo sanctuary. Its authors analysed historic demographic patterns and projected future population dynamics using an individual-based demographic model. The population has been growing at 6.7 per cent per year, driven by arrivals of new individuals (mean = 5.5 arrivals per year). Several model scenarios projecting varying arrival rates, releases and breeding scenarios clarify potential future growth trajectories for the sanctuary. This research illustrates how data on historic dynamics can be modelled to inform future sanctuary capacity and management needs. Les sanctuaires de faune secourent, réhabilitent, réintroduisent, et fournissent des soins pour toute la vie aux animaux orphelins et blessés. Comprendre les dynamiques de la population d’un sanctuaire—les motifs d’arrivée, mortalité, et de changements projetés de la taille de la population—permet une planification prudente pour les nécessités du futur. En se basant sur le travail déjà fait sur les dynamiques de la population chimpanzé (Pan troglodytes) dans les sanctuaires du Pan African Sanctuary Alliance (PASA; Faust et al. 2011), nous étendons notre analyse au seul sanctuaire bonobo par PASA. Nous avons analysé les motifs démographiques historiques et avons projeté les futures dynamiques de la population en utilisant un modèle démographique basé sur l’individu. La population augmente de 6.7 per cent par an, poussée par l’arrivée de nouveaux individus (moyenne = 5.5 arrivées par an). Plusieurs scénarios modèles montrent une trajectoire de potentielle croissance pour le sanctuaire. Cette recherche illustre comment modeler les données sur les dynamiques historiques pour informer la capacité future du sanctuaire et les besoins gestionnaires.

Democrats once dominated the “Solid South.” By the turn of the 21st century, Republicans had taken control. We are in the midst of the dawning of new, more progressive era. Theories explaining Republican growth provide little guidance, but a new perspective—Movers and Stayers theory—explains this recent growth in Democratic support and the ways in which population growth has produced it. Migratory patterns play a significant role in southern politics. Young, well-educated in-migrants fostered Republican growth in the last century. Today, these increasingly progressive young, well-educated movers are growing the Democratic Party. Movers bring their politics to their new communities. Their progressivism fosters the same among long-term residents (stayers) in their new communities. But the declining communities they left show the effects of their exit. In our racialized partisan environment, white stayers respond to the threat of declining communities by shifting to the right and identifying with the Republican Party. Conversely, African Americans respond to community threat by maintaining their progressivism. Few Latinos live in declining communities; Latino stayers in fast growing communities become more Democratic. While movers of retirement age are more conservative than younger movers, they are more liberal than those who retire in place—not quite the demographic windfall Republicans in aging areas have hoped for. These dynamics are altering the southern political landscape, and differences between growing areas and declining areas are accelerating. Absent a wholesale reinvention of southern politics along the lines of class or (possibly) age, the current partisan trajectory does not bode well for Republicans. The COVID-19 pandemic will not change that.

Phoenix, Arizona is one of America's fastest growing metropolitan regions. It is also its least sustainable one, sprawling over a thousand square miles, with a population of four and a half million, minimal rainfall, scorching heat, and an insatiable appetite for unrestrained growth and unrestricted property rights. In Bird on Fire, eminent social and cultural analyst Andrew Ross focuses on the prospects for sustainability in Phoenix--a city in the bull's eye of global warming--and also the obstacles that stand in the way. Most authors writing on sustainable cities look at places like Portland, Seattle, and New York that have excellent public transit systems and relatively high density. But Ross contends that if we can't change the game in fast-growing, low-density cities like Phoenix, the whole movement has a major problem. Drawing on interviews with 200 influential residents--from state legislators, urban planners, developers, and green business advocates to civil rights champions, energy lobbyists, solar entrepreneurs, and community activists--Ross argues that if Phoenix is ever to become sustainable, it will occur more through political and social change than through technological fixes. Ross explains how Arizona's increasingly xenophobic immigration laws, science-denying legislature, and growth-at-all-costs business ethic have perpetuated social injustice and environmental degradation. But he also highlights the positive changes happening in Phoenix, in particular the Gila River Indian Community's successful struggle to win back its water rights, potentially shifting resources away from new housing developments to producing healthy local food for the people of the Phoenix Basin. Ross argues that this victory may serve as a new model for how green democracy can work, redressing the claims of those who have been aggrieved in a way that creates long-term benefits for all. Bird on Fire offers a compelling take on one of the pressing issues of our time--finding pathways to sustainability at a time when governments are dismally failing their responsibility to address climate change.

Society’s greatest use of water is in food production; a fact that puts farmers centre stage in global environmental management. Current management of food value chains, however, is not well set up to enable farmers to undertake their dual role of feeding a growing population and stewarding natural resources. This book considers the interconnected issues of real water in the environment and “virtual water” in food value chains and investigates how society influences both fields. This perspective draws out considerable challenges for food security and for environmental stewardship in the context of ongoing global change. The book also discusses these issues by region and with global overviews of selected commodities. Innovation relevant to the kind of change needed for the current food system to meet future challenges is reviewed in light of the findings of the regional and thematic analysis.

This article reviews scholarship on the history and historiography of slavery in colonial and revolutionary United States. Slavery was a southern American institution associated primarily with cotton and a divinely ordained labour force of blacks. Southerners in the Chesapeake might realize that slaves once produced tobacco, and in low-country South Carolina and Georgia that they once grew rice, and in southern Louisiana that they once raised sugar cane, but most people, when they thought about slavery at all, thought about the growing of cotton and reckoned that an African workforce required no explanation. Few knew that at one time slavery lived in Massachusetts, Rhode Island, and Connecticut, that it had been vibrant in New York and Pennsylvania, and that slaves still worked in New Jersey in 1860. Even in the South, where the presence of a significant African-American population made the heritage of slavery undeniable and people generally recognized the meaning of that fact, most understood neither slavery's age nor its origins.

Cities occupy about 3 per cent of the Earth’s habitable land area and are home to one out of two humans worldwide; both estimates are predicted to grow. Urban space is thus becoming an important, novel ecological niche for humans and wildlife alike. Building on knowledge gathered by urban ecologists during the last half century, evidence of evolutionary responses to urbanization has rapidly emerged. Urban evolutionary biology is a nascent yet fast-growing field of research—and a fascinating testing ground for evolutionary biologists worldwide. Urbanization offers a great range of opportunities to examine evolutionary processes because of the radically altered and easily quantifiable urban habitat, and the large number of cities worldwide, enabling rigorous, replicated tests of evolutionary hypotheses. Urban populations are increasingly exhibiting both neutral and adaptive evolutionary changes at levels ranging from genotypes to phenotypes. The novelty of urban evolutionary biology is that these changes are driven by the cities we have built, including effects of infrastructure, pollution, and social characteristics of our urban neighbourhoods. It will thereby enrich the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. In a series of sixteen chapters written by leading evolutionary biologists working on urban drivers of evolution, Urban Evolutionary Biology is the first academic book in the field. It synthesizes current knowledge on evolutionary processes occurring literally on our doorstep, across the globe, and in each city independently.

In the second half of the first millennium CE, the Christian Middle East fractured irreparably into competing churches and Arabs conquered the region, setting in motion a process that would lead to its eventual conversion to Islam. This book argues that key to understanding these dramatic religious transformations are ordinary religious believers, often called “the simple” in late antique and medieval sources. Largely agrarian and illiterate, these Christians outnumbered Muslims well into the era of the Crusades, and yet they have typically been invisible in our understanding of the Middle East's history. What did it mean for Christian communities to break apart over theological disagreements that most people could not understand? How does our view of the rise of Islam change if we take seriously the fact that Muslims remained a demographic minority for much of the Middle Ages? In addressing these and other questions, the book provides a sweeping reinterpretation of the religious history of the medieval Middle East. The book draws on a wealth of Greek, Syriac, and Arabic sources to recast these conquered lands as largely Christian ones whose growing Muslim populations are properly understood as converting away from and in competition with the non-Muslim communities around them.

AbstractBreast cancer is the leading cause of death among Hispanic women. The number of Hispanic breast cancer survivors is increasing because the US Hispanic population is fast-growing and breast cancer survival is improving. However, this vulnerable population has received little attention. Obesity and weight gain affect Hispanic and African American/Black women disproportionately. Obesity affects several factors relevant to cancer survivorship, including cancer treatment and patient-reported outcomes such as health-related quality of life (QoL). As a first step toward addressing these issues, a pilot study was conducted to assess the feasibility of assembling a cohort of Hispanic breast cancer survivors in New Jersey. Methods were similar to those used in the ongoing Women’s Circle of Health Follow-Up Study, a cohort of African American/Black breast cancer survivors in New Jersey. Hispanic breast cancer survivors were very interested and willing to participate. There were interesting differences in body mass index and central adiposity between Hispanic and African American/Black breast cancer survivors, but both groups had a high prevalence of body fatness and comorbidities. Hispanic breast cancer survivors had lower QoL, particularly obese women. More research is needed to understand survivorship needs in minority and medically underserved women after a breast cancer diagnosis.

AbstractRemittances are one of the precious spin-offs of international migration in developing countries. They have been fast growing for the last decade, but like any other income, they fluctuate with economic conditions which are affected by several shocks, such as the ongoing covid 19 pandemic. Nevertheless, these transfers sometimes exceed Official Development Aid (ODA) and Foreign Direct Investment (FDI) in some parts of the World such as Sub-Saharan Africa, demonstrating their importance for promoting socio-economic development. This chapter focuses on Burkina Faso, a West African country where more than 80% of the population practice subsistence agriculture, and bear heavily the consequences of poor climatic conditions, exacerbated by the ongoing climate change. The country also has a great history of migration mainly written by its colonial past. Using data from several sources such as the World Bank indicators and national surveys, this chapter aims firstly to understand the trends of remittances flows in the country for the last decade. Secondly, using a national survey on migration conducted in the country, we found that receiving international remittances increases the probability of setting up a non-agricultural business. This result suggests that remittances can help households to set up businesses and be less dependent on climatic conditions.

AbstractThe increasing pressure on land coming from the raising needs of a fast-growing population puts public and private landowners and decision makers in front of difficult choices concerning the best use of limited land resources. On one hand, agricultural land and grassland need to be used to support human food requirements. On the other hand, these land uses create trade-offs with other ecosystem functions, assets and services, such as ecological connectivity, biodiversity and natural habitat maintenance. In this paper a prototype web-based dashboard is presented, that aims at allowing a fully-fledged calculation of the economic and environmental trade-offs between different land uses of any land patch (excluding urban areas and infrastructures) and in the Grand Duchy of Luxembourg. An agent-based model (ABM) coupled with life-cycle assessment (LCA) runs on the background of the dashboard. The coupled model allows the simulation of the farm business and the calculation of the revenues made by farmers in every land patch under different farm management scenarios. Crossing the information coming from the model with other tools would also allow to integrate local environmental trade-offs, such as degradation of local habitats or ecological connectivity, and not only global ones defined in a non-spatialized way. The dashboard has a potentially high value to inform policy, strategies, or specific actions (e.g., environmental stewardship programs that integrate economic convenience as a condition) and has the necessary flexibility to integrate new aspects related to territorial analyses as they become available.

AbstractCancer is the second leading cause of death among non-Hispanic white (NHW) men and women in the United States—but is the leading cause of death among Latinos (American Cancer Society, Cancer facts and figures for Hispanics/Latinos 2018–2020. American Cancer Society, Inc., Atlanta, 2018). The US Latino population was 60.6 million in 2019, as one of the largest, youngest, and fastest growing minority groups in the United States, its population will nearly double by 2060, making up 27.5% of the projected US population (Vespa et al., Demographic turning points for the United States: population projections for 2020 to 2060. U.S. Census Bureau, Washington, DC. Report No.: P25-1144. https://www.census.gov/library/publications/2020/demo/p25-1144.html.

Thus, advancing the science of cancer in Latinos has become an imperative for the nation, as Latinos will contribute a significant portion to its future cancer burden.

AbstractThe consequences of noise on the health of the population, as well as the policies and measures that can be adopted to minimise the problem, are a growing concern in Europe. This is highlighted in the recent report prepared in 2020 by the European Environment Agency (EEA), Environmental noise in Europe report (ENER). The main aim of the chapter is to quantify the noise generated by air transport at the EU level and discuss the consequences that this can have on the health of the population exposed to it. The summary of results for air transport contained in the aforementioned report will be presented, as well as those that the EEA presents in more detail for each country in the EEA 2019 Noise country fact sheets (NCFS). All results are derived from the 3rd Environmental Noise Directive (END) round, reported in 2017 and based on 2016 annual traffic data.

Abstract Despite a large and rapidly growing volume of research activity and output, primarily on the biological bases of antimicrobial resistance (AMR), epidemiological understanding of the causal mechanisms at play behind the apparent recent global rise in prevalence of AMR has, arguably, progressed very little. Despite this inconvenient fact, political imperative and expedience, among other drivers, have given substantial impetus to an interventionist approach against what are considered to be the culprits for the apparent growing prevalence of AMR and its impacts. Concern about the rise in prevalence of microbial infections that are resistant to therapeutic agents designed to kill them has arisen almost exclusively in relation to human health. (Public awareness and concern about antihelmintic resistance, for which the impacts are much more substantial for animal health, at least in developed temperate countries, are trivial by comparison). Nevertheless, antimicrobial drugs have been, and are, widely used in animal health and production throughout the world, and the contribution of this diverse usage to the ‘global AMR problem’ has historically been controversial. There is growing acceptance, notwithstanding the limitations in causal understanding noted previously, of AMR as an ecological problem of competing populations of microorganisms experiencing both natural and anthropogenic selection pressures in compartments that transcend species and other boundaries. Typifying what is described as a ‘One Health’ problem, AMR is therefore considered to be most amenable to conjoint mitigation efforts in all compartments: i.e. interventions in human health, animal health, food and the environment in a coherent manner. In animals, this calls into question the motivations and practices for antimicrobial drug usage, the majority of which are justified on the basis of promoting animal health and welfare and securing a food supply for a growing human population. Not surprisingly, there are great differences in animal husbandry and food demand, and in availability, access and regulation of antimicrobial usage in animals, and in surveillance of AMR, which are likely to be starkest between developed and developing countries. Thus, it is unlikely that the impacts of AMR, and the impacts of efforts to mitigate AMR that are directed to the ‘animal compartment’ of the ecosystem, will be felt equally across the world.

AbstractThe biodiversity of the oceanic islands of the Gulf of Guinea is valued internationally for its uniqueness and locally for its contribution to human welfare, but it is under growing anthropogenic pressure. We provide an overview of recent progress, ongoing challenges, and future directions for terrestrial and marine conservation. The islands were colonized in the late fifteenth century and have since relied heavily on international markets. Nevertheless, the livelihoods of many islanders depend directly on local natural resources, and growing human populations and economies are intensifying the use of these resources, including timber, land, and fisheries. Here we summarize conservation initiatives on the islands, including pivotal projects and achievements, as well as the rise of civil society and governmental engagement. We also review species and site-based conservation priorities and highlight the need for continuous updating based on ongoing research. Engagement in conservation has increased steadily in recent decades but not fast enough to counteract the growth of anthropogenic pressure on biodiversity. Fostering capacity building, environmental awareness, and research is thus urgent to ensure a thriving future for the islands, able to reconcile economic development and biodiversity conservation.

Abstract Romania is the EU Member State with the highest numbers of emigrants, according to Eurostat. The annual growth of the Romanian diaspora is one of the fastest in the world, and quite recent (over the past 20 years). In light of these developments, the institutional network for engagement with Romanians abroad, first established in the mid-1990s, has recently increased in an attempt to respond to the fast-growing Romanian diaspora. A Ministry entirely dedicated to maintaining the relations with the Romanian diaspora was formally institutionalized 10 years after Romania officially joined the EU in 2017, replacing scattered departments and institutional bodies. However, the role of the recently set up diaspora institutions still needs to be clarified and firmly determined. Policies were developed with the goal of ensuring the integration of Romanian citizens in their countries of residence, but also to encourage return to Romania. In particular, as few other European diaspora populations, the Romanian diaspora is represented in the Romanian Parliament by two Senators and four Deputies who represent the interests of three to five million Romanians abroad.

AbstractInternet surveys are the future of migration studies given that migrants engage more and more often in multidirectional movements and reside in multiple destination countries. The richness of the growing variety of geographical and temporal migrant trajectories pose particular challenges for quantitative researchers studying such spatially dispersed populations for which sampling frames are not available. The Web-based Respondent Driven Sampling (RDS) method addresses many of the challenges occurring in such a context. However, its implementation is not an easy task and does not succeed in all migratory settings. The goal of this chapter is to outline the opportunities and challenges associated with using Web-based RDS for researching migrant populations. While the RDS method can be powerful in fact-to-face interviews, its usefulness in Internet surveys is debatable. We examine this issue by using the example of a survey of Polish multiple migrants worldwide conducted in 2018–2019. We outline observations from the fieldwork (selection of seeds, formation of referral chains, etc.), and discuss the challenges of using Web-based RDS by focusing on the barriers to referral chain formation related to RDS assumptions and study design. The observed constraints relate to the definition of a target group, the management of incentives online, and the anonymity issues of online surveys.

AbstractDespite the fact that elderly people are the main incidental and continuously growing patient group with head and neck cancer, prospective trials focusing on special issues regarding head and neck surgery in elderlies are missing. To avoid complications during and after surgery in that patient category, comprehensive evaluation of functional status, comorbidities, performance status, social support and mental condition is mandatory. Regarding functional parameters, cardiac and respiratory conditions play a major role for any primary surgical procedure. Nevertheless, other comorbidities, medication and patients view on self-determination have carefully to be taken into consideration. It has repeatedly been shown that fit elderly individuals may benefit from intensive therapies like reconstructive surgery with microvascular free tissue transfer, concurrent chemoradiotherapy in the locoregionally advanced disease setting, and even from the standard first- and second-line palliative systemic therapies. Since it is well known that tolerance of systemic nonsurgical treatments in elderly people is less and therefore death from noncancer-related causes in that population is higher, moderate surgical procedures can be even more effective regarding quality of life in situations facing higher comorbidities, or functional constraints with limited life expectancy compared to nonsurgical standard approaches. Older people usually are at increased risk of postoperative complications. In particular, organ failure progresses much faster in multiple organ failure. The preoperative clarification of comorbidity for the avoidance of surgical complications is therefore of major importance. Close coordination with anesthesia and rapid postoperative mobilization are essential for this. Decision-making and treatment based on specific assessment in an experienced multidisciplinary team is key.

Analysis made in the article allows to conclude that the SME sector of high-tech manufacturing industries plays growing role in solving the problems of employment in developed countries. However, the major problem is that it is capable for only partial compensation of the loss of jobs in labour intensive sectors of the economy. Accumulation of knowledge of the population in industrialized countries together with high levels of computer literacy contributes to the revitalization of business services sellers that are mainly small sized businesses. In the era of fast growing technology industries, in particular related to IT sector, the role of SMEs in economy is increasing as they are main players in start -up communities and IT industries in general. Thus they can growingly contribute to the employment and labour market. The authors proceed from the assumption that service sector, and business services in particular, to a certain extent are capable of absorbing of workforce. This article argues that employment in the service sector in the developed economies is still largely focused on traditional sectors of activity. The purpose of the paper is to investigate latest trends of SMEs role in employment in the developed countries and the role of service sector in stabilizing labour market. Theoretical approaches, statistical data and policy analysis are used to research contemporary labour market trends. Knowledge - intensive services that are important from the point of view of economic dynamics, only start to concur positions in the developed countries.

Mechanical circulatory devices, such as ventricular assist devices (VADs), have become the life-saving alternative for the patients who suffered from severe heart failure (1). These devices were utilized as the bridge-transplant devices; however, due to the fast growing population of cardiovascular diseases and the eligible organ donations are very limited, these devices have been considered for the application of life-long implantation. The continuous-flow VADs offer better hemodynamic performance than the first generations pulsatile flow VADs, its compact design offers surgical advantage; however, due to the non-physiological blood flow past constricted geometrics where platelets are exposed to elevated wall shear stress (2), VADs are burdened with high incidence of thromboembolic events, mandating anticoagulation therapies for its recipients (3).

In recent years, negative demographic trends have been developing in Russia. The most important is a decline in the birth rate. Researchers are actively looking for new determinants of this process, on the basis of which measures of population policy can be developed. One of these determinants may be active grandparenting, which means the active participation of grandparents in the processes of caring for grandchildren. The aim of this study is to create a demographic and statistical model of a typical Russian grandfather, actively involved in childcare. We used the following methods: parametric and nonparametric independent samples tests (t-test, Mann-Whitney U test, median test), regression analysis, indirect method of calculations. As a result, two models were presented – statistical demographic model of the age when Russian men enter grandparenthood and demographic model of a typical Russian grandfather actively involved in childcare. Our study is a preliminary stage for a large-scale survey of grandparenting practices in Russia. The number of older people is growing fast, which makes this socio-economic group increasingly important for addressing the problems of demographic decline in Russia. Therefore, large-scale research of grandparenthood is crucial for more efficient policy-making in this sphere.

The fast-urbanizing Indian cities are grappling with rising ecological challenges. Pollution, water insecurity, urban heat, and flooding have increased the vulnerability of the urban population. There is a need to look at urban settlements as a functioning natural ecosystem delineated by administrative boundaries and to evaluate their health regularly through a comprehensive, easy to adopt, structured approach. This study aims to track and evaluate the ecosystem health of three different categories of urban settlements: a group of metropolitan wards, a growing peripheral city, and an emerging town, through adaption of Pressure- State-Response (PSR) framework developed by the Organisation for Economic Co-operation and Development (OECD)’. The methodology includes indices-driven change detection of ecosystem components and pressure points on the same, by using spatial and non-spatial data, developing an impact matrix, and prioritized eco plans for action. Increasing built-up surfaces in the peripheral city (11%) and the metropolitan wards (23%) show increased pressure on their ecosystem in the form of reducing pervious surfaces. Increasing water turbidity, land surface temperatures, and aerosol content in the air depict pressure hotspots requiring mitigative, restorative, and preventive action. A significant decrease observed in heavy vegetation in the metropolitan wards (58% in the last 5 years) and an increase in industrial activities and aerosol is observed in conjunction with increasing air temperatures and this points towards an impending change in its livability index due to anthropogenic pressures and climate change. The study concludes that a structured approach can aid in agile and sustainable management of our towns and cities and nature-based solutions provide an opportunity to restore the ecosystem balance.

Abstract With current rise of climate change worldwide, transport industry contributes up to 21% of the world’s total Green House Gases (GHG). In addition to that developing cities are facing great changes in urbanization, population growth and environmental concerns. In these instances, railway transportation is a top contender on land transport mode to achieve sustainable mobility in fast growing cities. For railway operation, apart from wheel-rail contact, the catenary system has a very high initial investment cost as well as associated maintenance cost. It is important to monitor the damage evolution of the catenary components for developing better maintenance strategies. This study utilizes a co-simulation between the railway catenary system dynamics and electrical power flow. With reference to Addis Ababa Light Rail Transit Service (AALRTS), the power and current drawn by the running train were calculated. Then the heat losses in the conductor wire were obtained with respect to train location on the line. This procedure was followed by thermal analysis that allowed us to obtain temperature rise in the conductor. The temperature results were used as some of the inputs in the dynamic explicit finite element model of the coupled catenary and sliding pantograph. From the finite element analysis, different quantities such as contact forces and pressures, temperature rise because of friction between sliding parts, and deflections of conductor were obtained. Furthermore, the fluctuations of train loads were taken into consideration in the calculation of power consumption and hence in temperature rise. Increase in loads resulted in increase of current drawn which increases the temperature of the mating parts, which in-turn affected frictional stresses and forces. The latter were the input parameters in Archard wear model for calculating wear volume from the catenary contact conductor. It was observed that at different scenarios of train passenger loadings, the train experiences an increase in energy consumption, which results in slight increase of contact conductor wear by material removal.

Automated data-driven decision-making systems are ubiquitous across a wide spread of online as well as offline services. These systems, depend on sophisticated learning algorithms and available data, to optimize the service function for decision support assistance. However, there is a growing concern about the accountability and fairness of the employed models by the fact that often the available historic data is intrinsically discriminatory, i.e., the proportion of members sharing one or more sensitive attributes is higher than the proportion in the population as a whole when receiving positive classification, which leads to a lack of fairness in decision support system. A number of fairness-aware learning methods have been proposed to handle this concern. However, these methods tackle fairness as a static problem and do not take the evolution of the underlying stream population into consideration. In this paper, we introduce a learning mechanism to design a fair classifier for online stream based decision-making. Our learning model, FAHT (Fairness-Aware Hoeffding Tree), is an extension of the well-known Hoeffding Tree algorithm for decision tree induction over streams, that also accounts for fairness. Our experiments show that our algorithm is able to deal with discrimination in streaming environments, while maintaining a moderate predictive performance over the stream.

Metropolitan Water District (Metropolitan) is a public agency charged with providing its service area with adequate and sufficient supplies of high quality water. Metropolitan was incorporated in 1928 by an Act of the California Legislature to serve its 13 original founding Member Agencies. Today, Metropolitan provides water to 26 cities and water agencies serving more than 19 million people in six counties in Southern California. On average Metropolitan delivers 1.7 billion gallons of water per day. California, the third-largest state in the U.S. by land area, has a diverse geography including foggy coastal areas, alpine mountain ranges, hot and arid deserts, and a fertile central valley. California is also the most populous state, exceeding 37 million people in 2010. California’s large population drives the interlinked demands for water and energy in the state. The water-energy nexus in California is highlighted by the fact that two-thirds of the population resides in Southern California while two-thirds of the state’s precipitation occurs in Northern California. Separating Southern California from the rest of the state is a series of east-west trending mountain ranges. Water conveyance projects have been constructed to address this north-south water imbalance and to also import supplies from the Colorado River, hundreds of miles east of Southern California population centers. The movement of water on this scale requires significant energy resources. The California Energy Commission (CEC) estimates that water-related energy use consumes 19% of the state’s electricity and 30% of its natural gas usage every year, and demand is growing. Energy management is a critical concern to Metropolitan and other California water agencies. These issues drive water and energy leaders to jointly manage energy and water use to ensure long-term mutual benefits.

Worldwide demand for petroleum grows steadily every year due to increasing demand in the United States as well as countries with fast-growing economies such as China and India, where the populations are striving to attain higher standards of living and lifestyle. Concern over this increased demand for petroleum in light of worries about reliable supply and global climate change has resulted in the US government passing new Corporate Average Fuel Economy (CAFE) standards and a Renewable Fuels Standard (RFS). The existing mandate in the US to blend ethanol into gasoline (approximately 15 billion gallons annually by 2015) had effectively committed 860 billion gallons of irrigation water in 2005 (approximately 2.4% of U.S. 2005 freshwater consumption) for producing fuel for the light duty vehicle (LDV) transportation sector. It is estimated that by 2030, nearly 2,700 billion gallons of water per year will be consumed and 4,700–6,400 billion gallons withdrawn to produce fuels used in LDVs. Irrigation for biofuels dominates the projected water usage for fuels production, but other alternatives to petroleum gasoline (coal to liquids, oil shale, and electricity via plug-in hybrid vehicles) will also contribute appreciably to future water consumption and withdrawal, especially on a regional level.

: The necessity to improve broiler thermotolerance and performance led to the following hypothesis: (a) thethermoregulatory-response threshold for heat production can be altered by thermal manipulation (TM) during incubation so as to improve the acquisition of thermotolerance in the post-hatch broiler;and (b) TM during embryogenesis will improve myoblast proliferation during the embryonic and post-hatch periods with subsequent enhanced muscle growth and meat production. The original objectives of this study were as follow: 1. to assess the timing, temperature, duration, and turning frequency required for optimal TM during embryogenesis; 2. to evaluate the effect of TM during embryogenesis on thermoregulation (heat production and heat dissipation) during four phases: (1) embryogenesis, (2) at hatch, (3) during growth, and (4) during heat challenge near marketing age; 3. to investigate the stimulatory effect of thermotolerance on hormones that regulate thermogenesis and stress (T₄, T₃, corticosterone, glucagon); 4. to determine the effect of TM on performance (BW gain, feed intake, feed efficiency, carcass yield, breast muscle yield) of broiler chickens; and 5. to study the effect of TM during embryogenesis on skeletal muscle growth, including myoblast proliferation and fiber development, in the embryo and post-hatch chicks.This study has achieved all the original objectives. Only the plasma glucagon concentration (objective 3) was not measured as a result of technical obstacles. Background to the topic: Rapid growth rate has presented broiler chickens with seriousdifficulties when called upon to efficiently thermoregulate in hot environmental conditions. Being homeotherms, birds are able to maintain their body temperature (Tb) within a narrow range. An increase in Tb above the regulated range, as a result of exposure to environmental conditions and/or excessive metabolic heat production that often characterize broiler chickens, may lead to a potentially lethal cascade of irreversible thermoregulatory events. Exposure to temperature fluctuations during the perinatal period has been shown to lead to epigenetic temperature adaptation. The mechanism for this adaptation was based on the assumption that environmental factors, especially ambient temperature, have a strong influence on the determination of the “set-point” for physiological control systems during “critical developmental phases.” In order to sustain or even improve broiler performance, TM during the period of embryogenesis when satellite cell population normally expand should increase absolute pectoralis muscle weight in broilers post-hatch. Major conclusions: Intermittent TM (39.5°C for 12 h/day) during embryogenesis when the thyroid and adrenal axis was developing and maturing (E7 to E16 inclusive) had a long lasting thermoregulatory effect that improved thermotolerance of broiler chickens exposed to acute thermal stress at market age by lowering their functional Tb set point, thus lowering metabolic rate at hatch, improving sensible heat loss, and significantly decreasing the level of stress. Increased machine ventilation rate was required during TM so as to supply the oxygen required for the periods of increased embryonic development. Enhancing embryonic development was found to be accomplished by a combination of pre-incubation heating of embryos for 12 h at 30°C, followed by increasing incubation temperature to 38°C during the first 3 days of incubation. It was further facilitated by increasing turning frequency of the eggs to 48 or 96 times daily. TM during critical phases of muscle development in the late-term chick embryo (E16 to E18) for 3 or 6 hours (39.5°C) had an immediate stimulatory effect on myoblast proliferation that lasted for up to two weeks post-hatch; this was followed by increased hypertrophy at later ages. The various incubation temperatures and TM durations focused on the fine-tuning of muscle development and growth processes during late-term embryogenesis as well as in post-hatch chickens.

Background PHS (pulmonary hypertension syndrome, ascites syndrome) is a serious cause of loss in the broiler industry, and is a prime example of an undesirable side effect of successful genetic development that may be deleteriously manifested by factors in the environment of growing broilers. Basically, continuous and pinpointed selection for rapid growth in broilers has led to higher oxygen demand and consequently to more frequent manifestation of an inherent potential cardiopulmonary incapability to sufficiently oxygenate the arterial blood. The multifaceted causes and modifiers of PHS make research into finding solutions to the syndrome a complex and multi threaded challenge. This research used several directions to better understand the development of PHS and to probe possible means of achieving a goal of monitoring and increasing resistance to the syndrome. Research Objectives (1) To evaluate the growth dynamics of individuals within breeding stocks and their correlation with individual susceptibility or resistance to PHS; (2) To compile data on diagnostic indices found in this work to be predictive for PHS, during exposure to experimental protocols known to trigger PHS; (3) To conduct detailed physiological evaluations of cardiopulmonary function in broilers; (4) To compile data on growth dynamics and other diagnostic indices in existing lines selected for susceptibility or resistance to PHS; (5) To integrate growth dynamics and other diagnostic data within appropriate statistical procedures to provide geneticists with predictive indices that characterize resistance or susceptibility to PHS. Revisions In the first year, the US team acquired the costly Peckode weigh platform / individual bird I.D. system that was to provide the continuous (several times each day), automated weighing of birds, for a comprehensive monitoring of growth dynamics. However, data generated were found to be inaccurate and irreproducible, so making its use implausible. Henceforth, weighing was manual, this highly labor intensive work precluding some of the original objectives of using such a strategy of growth dynamics in selection procedures involving thousands of birds. Major conclusions, solutions, achievements 1. Healthy broilers were found to have greater oscillations in growth velocity and acceleration than PHS susceptible birds. This proved the scientific validity of our original hypothesis that such differences occur. 2. Growth rate in the first week is higher in PHS-susceptible than in PHS-resistant chicks. Artificial neural network accurately distinguished differences between the two groups based on growth patterns in this period. 3. In the US, the unilateral pulmonary occlusion technique was used in collaboration with a major broiler breeding company to create a commercial broiler line that is highly resistant to PHS induced by fast growth and low ambient temperatures. 4. In Israel, lines were obtained by genetic selection on PHS mortality after cold exposure in a dam-line population comprising of 85 sire families. The wide range of PHS incidence per family (0-50%), high heritability (about 0.6), and the results in cold challenged progeny, suggested a highly effective and relatively easy means for selection for PHS resistance 5. The best minimally-invasive diagnostic indices for prediction of PHS resistance were found to be oximetry, hematocrit values, heart rate and electrocardiographic (ECG) lead II waves. Some differences in results were found between the US and Israeli teams, probably reflecting genetic differences in the broiler strains used in the two countries. For instance the US team found the S wave amplitude to predict PHS susceptibility well, whereas the Israeli team found the P wave amplitude to be a better valid predictor. 6. Comprehensive physiological studies further increased knowledge on the development of PHS cardiopulmonary characteristics of pre-ascitic birds, pulmonary arterial wedge pressures, hypotension/kidney response, pulmonary hemodynamic responses to vasoactive mediators were all examined in depth. Implications, scientific and agricultural Substantial progress has been made in understanding the genetic and environmental factors involved in PHS, and their interaction. The two teams each successfully developed different selection programs, by surgical means and by divergent selection under cold challenge. Monitoring of the progress and success of the programs was done be using the in-depth estimations that this research engendered on the reliability and value of non-invasive predictive parameters. These findings helped corroborate the validity of practical means to improve PHT resistance by research-based programs of selection.

Geelong and the Surf Coast are treated here as one entity although there are marked differences between the two communities. Sitting on the home of the Wathaurong Aboriginal group, this G21 region is geographically diverse. Geelong serviced a wool industry on its western plains, while manufacturing and its seaport past has left it as a post-industrial city. The Surf Coast has benefitted from the sea change phenomenon. Both communities have fast growing populations and have benefitted from their proximity to Melbourne. They are deeply integrated with this major urban centre. The early establishment of digital infrastructure proved an advantage to certain sectors. All creative industries are represented well in Geelong while many creatives in Torquay are embedded in the high profile and economically dominant surfing industry. The Geelong community is serviced well by its own creative industries with well-established advertising firms, architects, bookshops, gaming arcades, movie houses, music venues, newspaper headquarters, brand new and iconic performing and visual arts centres, libraries and museums, television and radio all accessible in its refurbished downtown area. Co-working spaces, collective practices and entrepreneurial activity are evident throughout the region.

This rapid review synthesises the literature from academic, policy, and knowledge institution sources on how demography affects labour markets (e.g. entrants, including youth and women) and labour market outcomes (e.g. capital-per-worker, life-cycle labour supply, human capital investments) in the context of sub-Saharan Africa. One of the key findings is that the fast-growing population in sub-Saharan Africa is likely to affect the ability to get productive jobs and in turn economic growth. This normally happens when workers move from traditional (low productivity agriculture and household businesses) sectors into higher productivity sectors in manufacturing and services. In theory the literature shows that lower dependency ratios (share of the non-working age population) should increase output per capita if labour force participation rates among the working age population remain unchanged. If output per worker stays constant, then a decline in dependency ratio would lead to a rise in income per capita. Macro simulation models for sub-Saharan Africa estimate that capital per worker will remain low due to consistently low savings for at least the next decades, even in the low fertility scenario. Sub-Saharan African countries seem too poor for a quick rise in savings. As such, it is unlikely that a lower dependency ratio will initiate a dramatic increase in labour productivity. The literature notes the gender implications on labour markets. Most women combine unpaid care for children with informal and low productive work in agriculture or family enterprises. Large family sizes reduce their productive labour years significantly, estimated at a reduction of 1.9 years of productive participation per woman for each child, that complicates their move into more productive work (if available). If the transition from high fertility to low fertility is permanent and can be established in a relatively short-term period, there are long-run effects on female labour participation, and the gains in income per capita will be permanent. As such from the literature it is clear that the effect of higher female wages on female labour participation works to a large extent through reductions in fertility.

The Sunshine Coast (unless otherwise specified, Sunshine Coast refers to the region which includes both Sunshine Coast and Noosa council areas) is a classic regional hotspot. In many respects, the Sunshine Coast has assets that make it the “Goldilocks” of Queensland hotspots: “the agility of the region and our collaborative nature is facilitated by the fact that we're not too big, not too small - 330,000 people” (Paddenburg, 2019); “We are in that perfect little bubble of just right of about everything” (Erbacher 2019). The Sunshine Coast has one of the fastest-growing economies in Australia. Its population is booming and its local governments are working together to establish world-class communications, transport and health infrastructure, while maintaining the integrity of the region’s much-lauded environment and lifestyle. As a result, the Sunshine Coast Council is regarded as a pioneer on smart city initiatives, while Noosa Shire Council has built a reputation for prioritising sustainable development. The region’s creative economy is growing at a faster rate that of the rest of the economy—in terms of job growth, earnings, incomes and business registrations. These gains, however, are not spread uniformly. Creative Services (that is, the advertising and marketing, architecture and design, and software and digital content sectors) are flourishing, while Cultural Production (music and performing arts, publishing and visual arts) is variable, with visual and performing arts growing while film, television and radio and publishing have low or no growth. The spirit of entrepreneurialism amongst many creatives in the Sunshine Coast was similar to what we witnessed in other hotspots: a spirit of not necessarily relying on institutions, seeking out alternative income sources, and leveraging networks. How public agencies can better harness that energy and entrepreneurialism could be a focus for ongoing strategy. There does seem to be a lower level of arts and culture funding going into the Sunshine Coast from governments than its population base and cultural and creative energy might suggest. Federal and state arts funding programs are under-delivering to the Sunshine Coast.

Wheat is the most widely grown crop on earth, together with rice it is second to maize in total global tonnage. One of the emerging threats to wheat is stripe (yellow) rust, especially in North Africa, West and Central Asia and North America. The most efficient way to control plant diseases is to introduce disease resistant genes. However, the pathogens can overcome rapidly the effectiveness of these genes when they are wildly used. Therefore, there is a constant need to find new resistance genes to replace the non-effective genes. The resistance gene pool in the cultivated wheat is depleted and there is a need to find new genes in the wild relative of wheat. Wild emmer (Triticum dicoccoides) the progenitor of the cultivated wheat can serve as valuable gene pool for breeding for disease resistance. Transferring of novel genes into elite cultivars is highly facilitated by the availability of information of their chromosomal location. Therefore, our goals in this study was to find stripe rust resistant and susceptible genotypes in Israeli T. dicoccoides population, genotype them using state of the art genotyping methods and to find association between genetic markers and stripe rust resistance. We have screened 129 accessions from our collection of wild emmer wheat for resistance to three isolates of stripe rust. About 30% of the accessions were resistant to one or more isolates, 50% susceptible, and the rest displayed intermediate response. The accessions were genotyped with Illumina'sInfinium assay which consists of 9K single nucleotide polymorphism (SNP) markers. About 13% (1179) of the SNPs were polymorphic in the wild emmer population. Cluster analysis based on SNP diversity has shown that there are two main groups in the wild population. A big cluster probably belongs to the Horanum ssp. and a small cluster of the Judaicum ssp. In order to avoid population structure bias, the Judaicum spp. was removed from the association analysis. In the remaining group of genotypes, linkage disequilibrium (LD) measured along the chromosomes decayed rapidly within one centimorgan. This is the first time when such analysis is conducted on a genome wide level in wild emmer. Such a rapid decay in LD level, quite unexpected for a selfer, was not observed in cultivated wheat collection. It indicates that wild emmer populations are highly suitable for association studies yielding a better resolution than association studies in cultivated wheat or genetic mapping in bi-parental populations. Significant association was found between an SNP marker located in the distal region of chromosome arm 1BL and resistance to one of the isolates. This region is not known in the literature to bear a stripe rust resistance gene. Therefore, there may be a new stripe rust resistance gene in this locus. With the current fast increase of wheat genome sequence data, genome wide association analysis becomes a feasible task and efficient strategy for searching novel genes in wild emmer wheat. In this study, we have shown that the wild emmer gene pool is a valuable source for new stripe rust resistance genes that can protect the cultivated wheat.

Recognizing the widespread concern that disruptions created by technology have not yet benefited middle- and low-income households, this study explores the potential of PropTech to positively impact the housing challenges in the region, with a particular focus on the poor or vulnerable populations. This study reveals several emerging trends that offer insight to those thinking about digital transformation in the housing and real estate sector for Latin America and the Caribbean and serve as the foundation for more research. PropTech startups are defined broadly as fast-growing actors that are developing technology-based business models for housing real estate markets. This includes companies operating on most phases of the housing value chain, from the housing units supply side (land, construction, access to services, and home improvement) to the demand side (financing, renting, buying, selling, and commercializing units). PropTech startups mainly address two key issues in the traditional real estate market: lack of transparency and processes inefficiencies. Reducing costs and making information available equalizes the markets playing field. The opportunity for PropTech startups to develop business models that cover lower income brackets is still largely unexplored. Currently, profitable businesses are mostly serving high-income bracket groups. Thus, large-scale solutions that would make investing in the low-income segment profitable remain an opportunity for PropTech companies to target. Also, opportunities remain for startups to explore housing solutions that strengthen adaptation to climate change and curb harmful environmental impact through technology innovations through retrofitting efforts or the repurposing of existing units. The report pays special attention to the different links in the value chain and highlights success stories that are having an impact on the current housing market, resulting in a snapshot of scalable, private-sector-led solutions currently deployed to solve pressing housing problems in the region.

Reproductive development is a critical determinant of agricultural yield. For species with unisexual flowers, floral secualdifferentation adds additional complexity, that can influenec productivity. The hormone ethylene has long, been known to play a primary role in sex determination in the Cucumis species cucumber (C. sativus) and melon (C. melo). Our objectives were to: (1) Determine critical sites of ethylene production and perception for sex determination; (2) Identify additional ethylene related genes associated with sex expression; and (3) Examine the role of environment ami prior fruit set on sex expression, pistillate flower maturation, and fruit set. We made progress in each of these areas. (1) Transgenic melon produced with the Arabidopsis dominant negative ethylene perception mutant gene, etrl-1, under the control of floral primordia targeted promoters [AP3 (petal and stamen) and CRC (carpel and nectary)], showed that ethylene perception by the stamen primordia, rather than carpel primordia, is critical for carpel development at the time of sex determination. Transgenic melons also were produced with the ethylene production enzyme gene. ACS, encoding l-aminocyclopropane-lcarboylate synthase, fused to the AP3 or CRC promoters. Consistent with the etr1-1 results, CRC::ACS did not increase femaleness; however, AP3::ACS reduced or eliminated male flower production. The effects of AP3:ACS were stronger than those of 35S::ACS plants, demonstratin g the importance of targeted expression, while avoiding disadvantages of constitutive ethylene production. (2) Linkage analysis coupled with SNP discovery was per formed on ethylene and floral development genes in cucumber populations segregating for the three major sex genes. A break-through towards cloning the cucumber M gene occurred when the melon andromonoecious gene (a), an ACS gene, was cloned in 2008. Both cucumber M and melon a suppress stamen development in pistillate flowers. We hypothesized that cucumber M could be orthologous to melon a, and found that mutations in CsACS2 co-segregated perfectly with the M gene. We also sought to identify miRNA molecules associated with sex determination. miRNA159, whose target in Arabidopsis is GAMYB[a transcription factor gene mediating response to10 gibberellin (GA)], was more highly expressed in young female buds than male. Since GA promotes maleness in cucumber, a micro RNA that counteracts GAMYB could promote femaleness. miRNA157, which in other plants targets transcription factors involved in flower development , was expressed in young male buds and mature flower anthers. (3) Gene expression profiling showed that ethylene-, senescence-, stress- and ubiquitin-related genes were up-regulated in senescing and inhibited fruits, while those undergoing successful fruit set up-regulated photosynthesis, respiration and metabolic genes. Melon plants can change sex expression in response to environmental conditions, leading to changes in yield potential. Unique melon lines with varying sex expression were developed and evaluated in the field in Hancock, Wisconsin . Environmental changes during the growing season influenced sex expression in highly inbred melon lines. Collectively these results are of significance for understanding regulation of sex expression. The fact that both cucumber sex loci identified so far (F and M) encode isoforms of the same ethylene synthesis enzyme, underscores the importance of ethylene as the main sex determining hormone in cucumber. The targeting studies give insight into developmental switch points and suggest a means to develop lines with earlier carpel-bearing flower production and fruit set. These results are of significance for understanding regulation of sex expression to facilitate shorter growing seasons and earlier time to market. Field results provide information for development of management strategies for commercial production of melon cultivars with different sex expression characteristics during fruit production.
