Full textAbstract:
To securitise an issue is to elevate it above politics to security status. At the global level, population growth has been securitised by a number of change agents. They have arrived at an understanding of population growth as existentially threatening and of population control as the best solution. This transformative process took place during the twentieth century and was enabled largely by the United Nations. However, in some Muslim states and societies where population growth is potentially threatening and securitisation of it is necessary, Islamic factors and agents might prevent this from happening. Events and experiences suggest that population control is antithetical to Islam. Muslim states and societies tend to experience higher growth and fertility rates than their non-Muslim counterparts. Furthermore, some Islamic agents have vocally opposed global and national population control objectives. Because of these two occurrences, Islam is assumed to be pro-natalist and anti-population control. It is also assumed that Islam is causal to high fertility and growth and the failure of control efforts. But is this necessarily true? Is population control antithetical to Islam? Moreover, will Islam and its agents prevent the securitisation of population growth by Muslim states and societies? These questions are explored through the case studies of Iran and Pakistan.

Full textAbstract:
The objective of this diploma thesis is to describe and to complexly evaluate Chinas one child policy from its introduction in 1979 till its abandonment in 2015. Theoretical part of thesis offers a detailed description of the policy, its application in real life, circumstances and aims that led to the implementation of the policy. Applied part of thesis analyses its effect on the fertility rate, population growth and economic growth. According to the results of this analysis one child policy helped to decline Chinas fertility rate and population growth, however its impact is just partial. The decline of Chinese population growth then contributed to the economic growth; my estimate is that it composed 40 % of average annual growth of real GDP per capita. One child policy is also responsible for raising sex ratio and ageing of population in China. These demographic problems let to its replacement by two child policy that probably wont solve these problems.

Full textAbstract:
This research examines why poverty has been persistent in all regimes that have tried to use public policy to eradicate it with no success. This research begins to examine the economic, fiscal, and current Federal Reserve monetary policy for an understanding of why poverty persists. The purpose of this experimental, cross-sectional design is to test the relationship between poverty level, population size, gross domestic product and the Gini coefficient. The most important outcome of the research is to understand if poverty is an unintended consequence of economic activity and not individual circumstance. In the dissertation, 5 U.S. states are examined in the year 2014. The data were collected using the U.S. Census Bureau and American Community Surveys. Using multiple regression, this research aimed to establish the minimum amount of expected poverty in the sample's population and gross domestic product (GDP). Using the results and further research, a predictive model could be created to understand how poverty, population, and GDP intersect to create stable economies. The key results yielded the Gini coefficient has no effect in predicting expected poverty levels. As determined by the model, Arizona would have a poverty decrease of 17.1% and Illinois' poverty would decrease by 7.7%. Georgia and Washington would increase by 9.4% and 21.8%, respectively. New York's levels would remain the same. One of the recommendations is continuing research to understand other quantitative factors that reduce or increase poverty numbers. These results help promote social change by possibly informing monetary policymakers more targeted solutions to mitigating poverty levels.

Full textAbstract:
The aim of the study is to investigate the current state of awareness of urban shrinkage inLiepājaby the key actors involved in the planning process. Last couple of hundred years have brought many transformations in urbanity that was always accompanied by the growth of the population and expansion of the city. However, the new patterns of urban development emerged in the last decades all over the globe, causing cities to lose the inhabitants resulting in urban shrinkage.Liepāja, the third largest city inLatvia, has lost a quarter of its population in last two decades and the trend continues. The long-term municipal planning document is being presented during this research in a light of which the research question is asked: “What is the current state of awareness of urban shrinkage inLiepājaby the key actors?” Utilising Flyvbjerg’s phronetic form of inquiry in combination with case study and repeated semi-structured interviews, the dominant planning views related to urban shrinkage are sought and analysed. The research identifies three underlying causalities that shape the decisions in planning and leave formidable consequences for the future of the city. The causalities identified and discussed in this paper are (1) the planning legacy; (2) the misconception; and (3) the political sensitivity of the urban shrinkage.

"The growth lobby and its absence the relationship between the property development and housing industries and immigration policy in Australia and France." Swinburne University of Technology, 2002. http://adt.lib.swin.edu.au./public/adt-VSWT20060710.144805.
Full textAbstract:
This thesis compares population policy and demographic outcomes in France and Australia from 1945 taking into consideration projections to 2050. These features are analysed using a theoretical approach derived from James Q. Wilson and Gary Freeman, flagging focused benefits/costs and diffuse benefits/costs of population growth, including growth fueled by immigration. This analysis is framed by the New Ecological Paradigm developed by Dunlap and Catton.
The oil shock of 1973 is identified as a major turning point where French and Australian policy directions and demographic trends diverge, notably on immigration.
It is established that in both countries there was a will for population stabilisation and energy conservation, which succeeded in France. In Australia, however, a strong, organised growth lobby over-rode this Malthusian tendency. A major force for growth lay in the speculative property development and housing industries. The specific qualities of the Australian land development planning and housing system facilitated land speculation. Speculative opportunity and profits were increased by population growth and, with decreasing fertility rates, the industries concerned relied increasingly on high immigration rates. In France, to the contrary, the land development planning and housing industries had no similar dependency on immigration and, since the oil shock, have adapted to a declining population growth rate.
The author concludes that France has a relatively Malthusian economy and that Australia has a relatively Cornucopian one. These observations may be extrapolated respectively to non-English speaking Western European States and to English Speaking Settler States.
Speculative benefits from population growth/immigration are illustrated by demonstrating a relationship between ratcheting property price inflation in high overseas immigration cities in Australia and the near absence of this inflation in low growth areas. In contrast this ratcheting effect is absent in France and French cities where population growth and immigration have little influence on the property market.
The research suggests that speculative benefits of high population growth have been magnified by globalisation of the property market and that these rising stakes are likely to increase the difficulty of population stabilisation and energy conservation under the Australian land development and planning system.
The thesis contains a substantial appendix analysing and comparing French and Australian demographic and energy use statistics.

Full textAbstract:
Apart from rapid economic growth, China has also experienced significant demographic changes over the past few decades. The People's Republic of China's family planning policies led to a sharp drop in the fertility rate. This MS Thesis aims to assess the possible consequences of the family planning policies on future growth of Chinese economy. The theoretical part defines population policy, assess the connections between population growth and economic growth and deals with the development of population theory over the years. The analytical part describes the family planning policy in China, its principles and instruments. Next it identifies the possible consequences of the demographic changes caused by the drop in fertility rate. The last part of the thesis focuses on two economically most severe consequences - population ageing and shrinking working age population - and evaluates its implications on future growth of Chinese economy.

A first-hand study of the population dynamics of South Florida Slash Pine (P. elliottii Engelm. var. densa) following a fire event provided insight to its recovery and dispersal following a fire. A natural fire (lightning-induced) occurred in the spring of 2000 at the T. Mabry Carlton, Jr. Reserve, Sarasota County, providing an opportunity to study aspects of slash pine in relation to fire. One objective of my research was to look at dispersal/recruitment conditions and slash pine dynamics in relation to fire. I looked at the varying degrees of tree mortality due to fire at different stands of slash pines.<br>ABSTRACT: I also looked at the stands in terms of stand composition and spatial arrangement of surviving adults. Finally, I studied how variable seedling establishment and survival was between stands. Few inferences could be drawn between fire and these individual analyses; however, all analyses revealed that at the scale of this study, pine flatwoods are patchy. I also looked at the dispersal of slash pines following a fire event. I modeled my research after Ribbens et al. (1994) and Clark et al. (1998), who took a phenomenological approach to dispersal modeling. This approach involved using distances between adults and seeds/seedlings and fecundity of adults to create dispersal models based on maximum likelihood estimates (MLE). I found that, while I could predict a model within acceptable parameters for most of the stands, more data was needed to predict models that better fit the data.<br>ABSTRACT: This finding, along with the fact that I recovered no seed data for analysis, suggests factors are contributing to dispersal and recruitment (e.g. cone-crop) that need to be accounted for in the future.<br>System requirements: World Wide Web browser and PDF reader.<br>Mode of access: World Wide Web.

O presente trabalho pretende analisar as principais tendências demográficas e de que forma influenciam o ambiente económico onde a política monetária é conduzida, causando direta ou indiretamente movimentos indesejados nas taxas de inflação. Recorrendo a uma técnica polinomial, estimamos a relação empírica entre a estrutura etária e a inflação para um painel de 24 países da OCDE durante o período 1961-2014. Encontramos uma correlação significativa entre demografia e inflação, consistente com a hipótese de que um aumento da população ativa causa pressões deflacionistas, enquanto uma maior parcela de dependentes e reformados está associada a taxas de inflação mais elevadas. Os resultados sugerem que o potencial impacto do processo de envelhecimento a nível global sobre a inflação deve ser tido em conta nas decisões de política monetária.<br>The ongoing demographic changes can affect the dynamic of economics in several ways, with implications for the conduct of monetary policy and price stability. This paper analyses the future prospects on demographic changes and how they are expected to influence the macroeconomic environment where monetary policy is conducted, which can directly or indirectly generate unwanted inflation dynamics. By adopting a polynomial technique, an estimation is carried out to determine the relationship between the age structure and inflation in a panel of 24 OECD countries over the 1961-2014 period. A significant correlation is found between demography and inflation, consistent with the hypothesis that an increase in the share of working-age population causes deflationary pressures, while a larger scale of dependents and young retirees are associated with higher inflation rates. The results suggest that the potential impact of the global ageing process on inflation should be taken into consideration in the decision making processes of monetary policy.

Thesis (M. Town and regional planning)--Stellenbosch University , 2000.<br>ENGLISH ABSTRACT: An ever increasing segment of the population in the current low density category
contributes to the sprawling South African city as we know it today. To provide for the
housing needs o f people, precious agricultural land is being used, and the historic character
o f towns is being destroyed. Densification of the city structure has been put forward as a
solution to this problem. In this way, different components of the city may be connected
and existing infrastructure may be optimally utilised.
The concept of densification is gaining popularity in all spheres o f planning. The
implementation of densification requires suitable policy, as well as the strict application of
the aforesaid. A densification policy must include consultation with all parties involved
with a view to finding a balance between the need for land for development purposes, the
conservation of agricultural land, the conservation of the historic character o f towns and
cities, as well as being in the public interest.
A theoretical investigation was done in which all aspects regarding densification, and its
implementation in the South African context were studied. Attention was also given to
policy formulation. This was followed by an empirical study, based on the Paarl municipal
region as an example, in an attempt to reconcile theory and practice.
It was found that although densification enjoys great support, the perception held by
professional planners as to appropriate methods for the achievement o f higher densities did
not correspond wholly with theoretical arguments in this regard. It was also found that it is
important to view densification in relation to the environment in which it is applied, and to
create an executable policy for a specifically designated area.<br>AFRIKAANSE OPSOMMING: Snelgroeiende bevolkingsgetalle in ‘n lae-digtheidsmilieu dra by tot die uitgebreide Suid-
Afrikaanse stad soos ons dit vandag ken. In die proses word kosbare landbougrond
gebruik om in die behuisingsbehoefte van die mens te voorsien en die historiese karakter
van dorpe word vernietig. As oplossing vir hierdie probleem word verdigting van die stad
voorgestel, om sodoende verskillende komponente van die stad te verbind en reeds
bestaande infrastruktuur tot die optimum te benut.
Die konsep van verdigting geniet toenemende gewildheid in alle sfere van beplanning.
Implementering van verdigting kan slegs deur die daarstelling van geskikte beleid en die
toepassing daarvan geskied. By die formulering van ‘n verdigtingsbeleid moet alle
rolspelers in die proses geraadpleeg word en ‘n middeweg tussen die behoefte aan grond
vir ontwikkeling, die bewaring van kosbare landbougrond, die bewaring van die historiese
karakter van ‘n stad en die publiek se belange gevind word.
‘n Deeglike teoretiese ondersoek is geloods, wat teoretiese aspekte omtrent verdigting en
die implementering van verdigting binne die Suid-Afrikaanse konteks ondersoek het. Daar
is ook aandag aan beleidsformulering gegee. Dit is opgevolg deur ‘n empiriese studie wat
binne Paarl se munisipale gebied uitgevoer is en teoretiese inligting met die praktyk
probeer versoen.
In hierdie studie is bevind dat alhoewel verdigting van die stad groot ondersteuning geniet,
die persepsie van professionele persone in die beplanningsprofessie oor metodes om hoër
digthede te bereik, nie heeltemal met die voorgestelde metodes vervat in teoretiese bronne
ooreenstem nie. Daar is ook bevind dat dit belangrik is om verdigting binne die konteks
van die omgewing waarin dit toegepas word, te beskou en sodoende ‘n uitvoerbare beleid
vir ‘n spesifieke omgewing op te stel.

Full textAbstract:
Abstract
In South Africa, more than 30 small, enclosed game reserves have reintroduced
lions over the last two decades, which now house more than 500 individuals. There
is a high risk of inbreeding in these fragmented, fenced and isolated populations,
which may be compounded by a lack of management guidelines. A population of
11 founder lions Panthera leo was reintroduced to Madikwe Game Reserve in
1995, and this population has in turn become a source for reestablishing other
populations. Only four lineages were reintroduced, founder males were related to
founder females, and since 1997, only one male lineage maintained tenure for
49 years, resulting in breeding with direct relatives. Interventionist management
to limit lion population growth and inbreeding in Madikwe has taken the form of
translocating, trophy hunting and culling of mainly sub adult lions. Despite this
management, inbreeding started 5 years after reintroduction. Reproductive performance
and thus population growth in Madikwe were dependent on the overall
lion population density. When lion density was low, females first gave birth at a
significantly younger age and produced larger litters, resulting in a high population
growth rate, which decreased significantly when lion density in the park reached
carrying capacity, that is, 61 lions. This might have profound consequences for
future reestablishment of lion populations when restocking new reserves: our study
illustrates the need for founder populations of reintroduced endangered predator
species to be as large and genetically diverse as possible, and thereafter new genetic
material should be supplemented. The development of such management guidelines
is becoming very important as large predator populations become increasingly
fragmented and managed as metapopulations.

Thesis (M.Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 1999.<br>Includes bibliographical references (leaf 52).<br>This thesis will focus on how urban housing design reflects the new one-child family population policy in the traditional urban context in Beijing, China. The population policy has changed the size and structure of traditional family, and further affected children's growing up environment. Children, used to grow up in a joint family of three generations in a traditional courtyard house, now have isolated by apartment box. The traditional social and spatial relationships among children, families, and neighbors have been extremely weakened. My intention is to restore the lost relationships for lonely children in a high density residential complex. This complex, transformed from the traditional single story courtyard house, becomes one big house, where all neighbors live under one roof as one big family. As a consequence, children in a one child family still have the same feeling of multi generations living together as their old generations had before.<br>by Mingzheng Gao.<br>M.Arch.

Full textAbstract:
The objectives of my research were to test the hypothesis that compensatory (density-dependent) growth of sandbar shark (Carcharhinus plumbeus) occurred after severe population reduction, to describe the juvenile sandbar shark fauna present in the Chesapeake Bay during 1980-81 and 1990-93, and to perform demographic analyses to examine potential population growth. Age and growth of sandbar sharks were investigated by counting rings in vertebral samples collected in 1980-81 and 1991-92. Age at maturity was 15-16 years for both sample periods and both sexes. For sexes combined, the von Bertalanffy growth parameters were L&\sb{lcub}\infty{rcub}& = 199 cm precaudal length (PCL), K = 0.057, t&\sb{lcub}\rm o{rcub}& = &-&4.9 years for the 1980-81 sample and L&\sb{lcub}\infty{rcub}& = 164 cm PCL, K = 0.089, t&\sb{lcub}\rm o{rcub}& = &-&3.8 years for the 1991-92 sample. Significant differences in size at age and annual incremental growth of juveniles suggest a small increase in juvenile sandbar shark growth rate between the two sampling periods. Annual catches of sharks &>&105 cm PCL declined substantially between survey periods. Males and females were present in a 1:1 ratio. During 1980-81 juveniles ranged in age from 0-7 yr, but in 1990-93 few sandbar sharks over age 4 were taken. Based on the best estimate of fishing mortality the population ranged from 10,087 to 8509 sharks from 1989-1993. Annual year-class size was variable but all estimates were within one order of magnitude. Juvenile sandbar sharks declined in abundance by approximately 15% between 1989 and 1993. The annual population growth rate was highest under a scenario of natural mortality (M) = 0.05 and maximum age of 30 yr, but was only 11.9%/yr. at higher juvenile mortality rates and adult M fixed at 0.10, the best estimate of M for sandbar sharks, population growth rate was only 2.6%/yr. Adding fishing mortality (F) at immature ages caused the population to decline unless F levels were &<&0.10 and 0.05 at maximum age = 30 and 60 yr, respectively. It is apparent that sandbar shark populations will decline under any substantial fishing mortality on immature ages, and mature fish can only be exploited at very low levels of fishing mortality.

Full textAbstract:
Aspects of the asymptotic behaviour of cell-growth models described by partial differential equations, and systems of partial differential equations, are considered. The models considered describe the evolution of the size-distribution or age-distribution of a population of cells undergoing growth and division. First, the relationship between the behaviour, with and without dispersion, of a single-compartment size-distribution model of cell-growth with fixed-size cell division (where cells can only divide at a single, critical size) is considered. In this model dispersion accounts for stochastic variation in the growth process of each individual cell. Existence, uniqueness and the asymptotic stability of the solution is shown for a size-distribution model of cell-growth with dispersion and fixed-size cell division. The conditions for the analysis to hold for a more general class of division behaviours are also discussed. A class of nonlocal ordinary differential equations is studied, which contains as a subset the nonlocal ordinary differential equations describing the steady size-distributions of a single-compartment model of cell-growth. Existence of solutions to these equations is found to be implied by the existence of 'upper' and 'lower' solutions, which also provide bounds for the solution. A multi-compartment, age-distribution model of cell-growth is studied, which describes the evolution of the age-distribution of cells in different phases of cell-growth. The stability of the model when periodic solutions exist is examined. Sufficient conditions are given for the existence of stable steady age-distributions, as well as for stable periodic solutions. Finally, a multi-compartment age-size distribution model of cell-growth is studied, which describes the evolution of the age-size distribution of cells in different phases of cell-growth. Sufficient conditions are given for the existence of steady age-size distributions. An outline of the analysis required to prove stability of the steady age-size distributions of the model is also given. The analysis is based on ideas introduced in the previous chapters.

Building on Lapham and Mauldin's "Program Effort and Fertility Decline" framework and policy evaluation's theory, the author developed two models to examine the impact of family planning programs on contraceptive prevalence and fertility under the constraints of socioeconomic development and demand for family planning. The study employed path analysis and multiple regression on data from the 1982 program effort study in 94 less developed countries (LDCs) by Lapham and Mauldin and 98 LDCs of the 1989 program effort study by Mauldin and Ross. The results of data analyses for all data sets are consistent for the most part. Major findings are as follows: (1) A combination of program effort and socioeconomic development best explains the variation of contraceptive prevalence. (2) Among socioeconomic variables, female literacy exerts the strongest direct and indirect influences to increase contraceptive prevalence and indirect influence to decrease total fertility rate. (3) Christianity performs a significant role in reducing contraceptive prevalence. (4) Among program effort components, availability and accessibility for fertility-control supplies and services have the most influence on contraceptive prevalence. (5) When controlling for demand for family planning, female literacy and Christianity have expected and significant relationships with contraceptive prevalence. Availability and accessibility to fertility-control supplies and services exerts a positive and statistically significant impact on contraceptive prevalence. Demand for family planning has a positive and statistically significant effect on program variables, availability, and contraceptive prevalence. (6) There is a strong inverse relationship between contraceptive use and fertility. Demand for family planning, program effort, and socioeconomic development influence fertility through contraceptive prevalence. The findings of this study suggest that governments in LDCs should give priorities to increasing female education and availability of contraception to effectively reduce fertility.

Empowered patient or empowered physician. An analysis of the importance of the gatekeeper in the health delivery system. This paper examines the important role of the gatekeeper in the health delivery system. A simple theoretical model is developed which compares the resource allocation when physicians act as gatekeepers with the decisions taken when patients are empowered. It is shown that even when there is no asymmetry of information---and so patients and doctors are equally able to identify the appropriate therapy---that the institutional arrangement matters. Patients demand more time with physicians when they are empowered whereas physicians want to spend more time developing their expertise when they are empowered. The reaction of physicians and patients to changes in policy instruments also differs across institutional arrangements. The analysis also draws attention to the design of the compensation scheme for physicians, and investigates the benefits of using a non-linear scheme.
Wealth, health, and the pursuit of happiness. This paper provides a theoretical framework to illustrate the relationship between income, utility maximization, and healthy choices. The analysis indicates that the choices of individuals who maximize utility are not the same as those arising were the individual to maximize wellness. In fact, rational individuals will over-eat and under-exercise relative to health maximizing levels. Yet as individuals get wealthier, they have better health. The paper also compares different strategies for health promotion. Income redistribution may lead to a net increase in population health and in social welfare. By contrast, policies that specifically target lifestyle choices may succeed in persuading citizens to choose a health-maximizing lifestyle, but result in a net welfare loss to society.
An empirical investigation of household income and income polices on obesity in Canada. Using the master files of the Canadian Community Health Survey (CCHS), this paper examines the effect of income on obesity and individuals' body-mass index. An instrumental variable technique is employed to derive consistent estimates of this effect and to take account of the possible endogeneity between income and body weight. It is found that higher income will lead to lower body weight for women, while its effect on the body-weight outcome of men is unclear. This chapter uses the estimates of the relationship between income and body weight to simulate the impact of government income policies---like social assistance and child support---on obesity. It is shown that incomes policies may not only decrease income inequality but may also contribute to a lower incidence of obesity amongst the poorer population thus decreasing overall health care costs.

Full textAbstract:
This study is directed toward the relationship between population growth and socioeconomic development in Nigeria for the period 1960-1984. A controlled population growth would positively affect every segment of the economic and social environment. With hunger and starvation, disease, poverty and illiteracy plaguing large portions of the world, Nigeria's limited resources would best be utilized if shared among a smaller population, Nigeria, like other developing African countries, does not have an official population control policy. The diversity in the Nigerian culture, the controversial nature of the subject of population control, and possibly, implementation difficulties, account for the absence of a population control policy in Nigeria. This study offers in its concluding section some policy recommendations on how to tackle Nigeria's population problem.

Full textAbstract:
Neoclassical economic growth model theory identifies technology as a key promotor of productivity and long-run economic growth. Theory and literature on the subject has grown significantly since Robert Solow's seminal work in 1956. Notwithstanding the substantial literature, gaps remain in several aspects, including the establishment of suitable metrics that can be applied to assess the impact and influence of certain technologies, and in particular industrial robots, on the modern economy.
Given these gaps in knowledge, the aim of this study was to support exploratory research that has found industrial robot density, as a proxy for technology and automation, to be a relevant metric that correlates with productivity and economic growth. Decision and policy makers aiming to improve manufacturing productivity and economic development should find this metric and the associated analysis beneficial in achieving a better understanding of forces that influence economic performance. This research was quantitative by design, and used inferential analysis of data from diverse countries. The suitability of industrial robot density as an econometric measure was tested with statistical methods.
Strong statistical correlations were found between industrial robot density, productivity and economic growth in the manufacturing sector. These findings supported existing growth theory quantitatively, while addressing limitations in previous research by using a larger sample that included developing countries for the first time.<br>Mini Dissertation (MBA)--University of Pretoria, 2017.<br>pa2017<br>Gordon Institute of Business Science (GIBS)<br>MBA<br>Unrestricted

Full textAbstract:
Due to obstruction in the national plan of urbanization in Tripoli (Libya) and population growth, serious problems have emerged in the form of random settlements, overcrowding and poor infrastructure. After more than two decades of inertia, the government has created a national plan in order to resolve the problems, hence it has enforced the demolition of some zones and modified other (irregularly built) ones, however the process is extremely costly. This research introduces a solution through cellular automata (CA) model to predict growth trends; size of residential, industrial and utilities areas; and to project future population. The model is implemented using digitized land use maps of Tripoli to indicate each areas as group of cells to predict their growth. The model incorporates two types of fuzzy rules bases, the first of which is based on the inputs population and area, and the second of which is based on the three inputs of population, area and density. The population prediction is performed using three scenarios, namely decreasing, fixed and increasing growth rates, such that all possibilities of growth are covered. In addition, the residential area prediction is performed based on two cases: normal density and low density. The former is introduced since new areas tend to have more open spaces and bigger houses. Furthermore, the model considers the growth of the industrial areas to be slower than that of residential areas. The model is developed and validated for the period of 1980 to 2010. The prediction is performed for thirty years from 2010 to 2040. In addition to the CA model, a regression model is developed and tested on the three growth scenarios for the same period (30 years). The prediction results are very close for 2040 in terms of population. The model incorporates the introduction of public services areas that are distributed equally on the growth areas, which occupy about 15-20% of the total area. This model can help the government to develop areas in a proper way and controls the expansion to have well layout and planned of the city, improving people's standard of living sustainably, while protecting the environment with better planning.

Using semi-structured interviews, key stakeholders were asked about their experiences with 15 to Finish: a 2014 completion message that led to a financial aid policy. Through snowball sampling, participants included administrators from the state higher education system, senior administrators from academic and administrative units, professional and academic advisors, and students. Data was also collected through meeting agendas and agency reports. Interviews were transcribed and all text was analyzed using hermeneutic phenomenology. Three key themes were constructed: (a) administrators and faculty help students because it is the right thing to do; (b) messaging and communication of a policy and campaign can be divisive and should employ a communications plan; and (c) Nevada is experiencing a change in college culture from access to completion.</p><p>

Full textAbstract:
We initiated bait station surveys for black bears in southwestern Virginia in 1999. Bait station surveys are intended to be used as an index to follow bear population trend over time. We compared the bait station visitation (black bear visitation) to black bear harvest and mast surveys 1999 = 2002. The mean bait station visitation rate during 1999 - 2002 was 15.3% (SE = 2.89, n = 4). The number of bears harvested in the 3 counties that also had bait station surveys was 48 (31 males, 17 females), 59 (44 males, 15 females), 45 (32 males, 13 females), and 43 (26 males, 17 females) in 1999, 2000, 2001, and 2002, respectively. Harvest of males and females differed (n = 2, F = 19.44, df = 1, P = 0.0045). Bait station visitation and female harvest had a strong functional relationship with a negative slope (n = 4, r = -0.78, P = 0.22). The strongest relationship was between male harvest and total harvest (n = 4, r = 0.97, P = 0.03). Mean index to mast production for 1999 - 2002 was 2.3 (range 1.5 - 3.1), 2.7 (range 1.8 - 3.4), 2.3 (range 1.6 - 3.6), and 1.6 (range 1.2 - 2.4), respectively. The overall summary for mast production for the same years was described as fair, good, fair, and poor to fair. Mast production was significantly different between years (n = 4, F = 3.44, df = 3, P = 0.0326), and soft and hard mast production appeared to be above average in 2000. This corresponded with the lowest visitation (10.2%) of the 4 years. There was no correlation between bait station visitation and mast production (n = 4, r = 0.11, P = 0.87).
Since 1998, the annual bear harvest in Virginia has exceeded 900 individuals (with the exception of 824 in 2001), and peaked in 2000 when 1,000 bears were harvested. Though harvest rates were high, a reliable population estimate did not exist for black bears in Virginia. We estimated population size, growth rate, and minimum viable population size using data collected between 1995-2000. We used Jolly-Seber, direct recovery, and minimum population size methods to estimate population size. The Jolly-Seber method estimate of adult female density was 0.23-0.64 bears/km2, and 0.01 bears/km2 for adult males. We estimated a density of 0.09-0.23 bears/km2 for all sex and age classes using direct recovery data. Using minimum population size, we found adult female density was higher than any other sex or age class (n = 6, t = 2.02, df = 40, P < 0.0001) with an average density of 0.055 adult females/km2.
We used mark-recapture data collected from 148 individual bears (96 males:52 females) captured 270 times in program MARK to estimate survival using recapture, dead recovery, and Burnham's combined models. Adult females had the highest survival rate of 0.84-0.86, while yearling males had the lowest with 0.35. Using direct recovery data, adult females again had the highest survival rate with 0.93 (0.83-1.0) and 3-year old males had the lowest with 0.59 (0.35-0.83). We estimated growth rate using population estimates from Jolly-Seber, direct recoveries, and minimum population size methods. The lowest growth rate estimated was for all females (ages lumped) using minimum population size data (λ=0.82). Direct recovery data for all bears (sex and age lumped) during 1995 - 2000 showed the highest positive annual growth rate (λ = 1.24).
We developed a population model using Mathcad 8 Professional to determine population growth rate, MVP, and harvest effects for an exploited black bear population in southwestern Virginia. We used data collected during the CABS study (1995 - 2000) in the model including population estimates derived from direct recovery data, age and sex specific survival rates, and cub sex ratios. When we used actual population values in the model, the bear population in southwestern Virginia did not go extinct in 100 years (l = 1.03, r = 0.03). When we reduced adult female survival from 0.94 to 0.89, the probability of extinction in 100 years was 3.0% and l = 0.99 (r = -0.01; Table 3.2). When the survival was reduced by an additional 0.01 to 0.88, the probability of extinction increased to 13.0% (l = 0.99, r = -0.01). Growth rate and extinction probabilities were very sensitive to adult female survival rates. Two-year old and 3-year old females did not impact extinction probabilities and growth rates as much as adult females. Their survival could be decreased by 44.0%, and still be less than the 5.0% extinction probability.<br>Master of Science

Over the past century, population growth and favourable demographic factors have strongly influenced the U.S. housing market. Demographic factors such as age cohorts, race and ethnicity have formed longstanding housing trends and preferences. These demographic factors are expected to continue as the U.S. population increases over the next few years.
In the U.S. West, the population is expected to increase the most compared to the rest of the country. As a result, this thesis examined six Metropolitan Statistical Areas (MSAs) in the U.S. West and forecast housing demand in relation to the number of units of housing starts and the volume of construction lumber required to build these housing units.
The population and demographic data from 2006 to 2015 for these six MSAs were analysed and results indicated cities with a large population base are expected to have higher housing starts demand and lumber consumption than cities with a smaller population base. Furthermore, different population age cohorts defined as Baby Boomers, Generation X and Generation Y will also affect housing preferences in terms of the size and type of the houses. Another key demographic trend is the mix in race and ethnicity, specifically with the high percentage of Hispanic population in the U.S. West. The Hispanics are the largest and fastest growing ethnic population in the U.S. West and are expected to be a major population segment influencing the future of the housing market.

Full textAbstract:
The motivating problem concerns the estimation of the growth curve of solitary corals that follow the nonlinear Von Bertalanffy Growth Function (VBGF). The most common parameterization of the VBGF for corals is based on two parameters: the ultimate length L∞ and the growth rate k. One aim was to find a more reliable method for estimating these parameters, which can capture the influence of environmental covariates. The main issue with current methods is that they force the linearization of VBGF and neglect intra-individual variability. The idea was to use the hierarchical nonlinear model which has the appealing features of taking into account the influence of collection sites, possible intra-site measurement correlation and variance heterogeneity, and that can handle the influence of environmental factors and all the reliable information that might influence coral growth. This method was used on two databases of different solitary corals i.e. Balanophyllia europaea and Leptopsammia pruvoti, collected in six different sites in different environmental conditions, which introduced a decisive improvement in the results. Nevertheless, the theory of the energy balance in growth ascertains the linear correlation of the two parameters and the independence of the ultimate length L∞ from the influence of environmental covariates, so a further aim of the thesis was to propose a new parameterization based on the ultimate length and parameter c which explicitly describes the part of growth ascribable to site-specific conditions such as environmental factors. We explored the possibility of estimating these parameters characterizing the VBGF new parameterization via the nonlinear hierarchical model. Again there was a general improvement with respect to traditional methods. The results of the two parameterizations were similar, although a very slight improvement was observed in the new one. This is, nevertheless, more suitable from a theoretical point of view when considering environmental covariates.

Feral swine are a nuisance species across the United States that costs around $1.5 billion each year in agricultural, environmental, and personal property damages. In the last ten years the population of feral swine is estimated to have quadrupled and novel population control methods are needed. Furthermore, feral swine are known carriers of zoonotic diseases such as brucellosis, which threatens both livestock biosecurity and public health. Recombinant multimeric gonadotropin-releasing hormone (mGnRH) has been previously used as a subunit vaccine to induce immunocontraception in feral pigs. However, potent adjuvants and large amounts of purified antigen are needed to elicit a robust anti-GnRH immune response and current delivery methods are limited. Brucella suis strain VTRS2 can be used as a novel platform to deliver mGnRH without the use of antibiotic resistant markers. Strain VTRS2 was created by deletion of the LPS biosynthesis gene wboA as well as the leuB gene required for leucine biosynthesis inside the nutrient-depleted intracellular environment occupied by Brucella. Mutations in wboA are known to attenuate Brucella strains such as the vaccine strain B. abortus RB51, however strain RB51 is rifampin resistant and has poor efficacy in swine. Strain VTRS2 confers significant protection against B. suis challenge in mice and additionally shows evidence of protection in feral swine. Furthermore, the mGnRH antigen can be delivered using the pNS4 plasmid (which expresses leuB under its native promoter) thus maintaining the plasmid in strain VTRS2 under leucine-deficient conditions while expressing recombinant antigen in the host. The murine model was used to determine the clearance kinetics of strain VTRS2-mGnRH and to measure vaccine efficacy against challenge by virulent B. suis 1330. Subsequently the effects of the VTRS2-mGnRH vaccine on fertility were assessed in breeding trials in mice. Strains VTRS2 and VTRS2-mGnRH were found to be protective against virulent Brucella suis challenge. Strain VTRS2-mGnRH elicited an anti-mGnRH antibody response in vaccinated mice, though an effect on fertility was not observed. An improved vaccine against brucellosis in swine, which also confers immunocontraception without the introduction of antibiotic resistance, could become an important tool in the management of this nuisance invasive species.<br>Ph.

Full textAbstract:
Large increases in water demand with very little recharge have strained Libya’s groundwater resources, resulting in serious declines in water levels and quality, especially along the Mediterranean coast where most of the agricultural, domestic and industrial activities are concentrated. To meet these increases, Libya turned to desalination as a supplementary water resource as early as 1964. Both thermal and membrane desalination technologies have been used. This study shows that the problem of water scarcity is likely to increase further in the future. This study has three aims: first, to estimate the historical relationship between population growth and the various uses of water; second, to forecast water consumption according to the various uses; third, to estimate the elasticities of water demand and examine the effect of price, income, population and temperature on water demand in Libya in the short and long-run. To achieve these aims, an econometric model of Libyan water demand is constructed and estimated for the period 1975-2005, using the Box-Jenkins approach to forecast water demand and the Engle-Granger two-step approach to estimate the short and long-run elasticities of water demand. As a result this study provides considerable information for policy makers concerning current and future Libyan water demand. By examining the relationships between population growth and the future consumption of water in Libya, it is possible to reach the following conclusions. • Population growth in Libya will be very high. • Population elasticities for water demand are elastic for agricultural, domestic and industrial purposes. Water demand for all purposes is extremely elastic. • Most of the population and agricultural lands are concentrated in the northern part of the country. • The Libyan economy depends heavily on underground water. • In Libya, as a whole, water demand will increase. Available water in 2020 will be less than half of water demands, implying an increase in the water scarcity problem over time. • The short and long-run price elasticties are negative, suggesting that there is an inverse relationship between water demands and price. Also, these elasticities indicate that water use is generally inelastic with respect to price. • The income elasticities are all positive in the short and long-run. This result accords with demand theory, implying that water is a normal good. • The estimation results suggest that, in the long-run, water demand for agricultural, domestic and industrial use is highly elastic for population and inelastic for price and income. • The short-run elasticities are less than the long-run elasticities, as economic theory suggests. Also, all elasticities in the short-run are less than one. This implies that water demand is inelastic in the short-run.
