Distributional Impact of Globalization-Induced Migration: Evidence from a Nigerian Village

One of the contentious issues about the globalization process is the mechanism by which globalization affects poverty and inequality. This paper explores one of the various strands of the globalization?inequality?poverty nexus. Using microlevel survey data from over 300 poor households in the small village of Umuluwe (about 30 miles west of the regional capital of Owerri) in Southeast Nigeria, the paper investigates whether individuals who migrate from the village to take advantage of the urban-biased globalization process do better than non-migrant villagers. The paper concludes that while the migrant villagers tend to earn slightly higher incomes than the non-migrant villagers, the poverty profiles of both categories of households are essentially the same. In other words, and contrary to conventional wisdom, globalization has not succeeded in alleviating poverty amongst the poor villagers who explicitly took advantage of the process. The paper argues that, by changing relative prices in the urban areas, structural adjustment appears to have eliminated any advantage that globalization may have bequeathed to the migrant villagers.migration, Nigeria, poverty, prices

Graduate Education in Ecological Economics

Interest in graduate education in ecological economics is increasing. However, no formal plan of study for a Ph.D. in ecological economics has been disseminated. The lack of a formal plan is problematic as the field of ecological economics matures, interest grows, and new programs are being developed. This paper attempts to fill a void by creating a program of study addressing the proficiencies a graduate student in ecological economics should have upon completion of his/her Ph.D. based on the US educational system. The plan of study presented in this paper has been developed to make the graduate of an ecological economics program as competitive on the labor market as students awarded traditional economics degrees. The plan I describe is created to meet the requirements necessary for a Ph.D. in ecological economics. Further, fields of specialization are suggested to complement the core of an ecological economics program, to enhance the education process and to give the student with an ecological economics degree a higher level of marketability.

Parenting in the early years: effectiveness of parenting support programs for Indigenous families

This resource sheet examines programs for Australian Indigenous families that effectively support parenting in the early years. This is not a systematic review of all programs; instead, it presents briefly on the evidence for parenting programs generally and then focuses specifically on the evidence for such parenting programs in helping Indigenous families. Programs that focus on supporting parenting in the early years aim to influence the behaviours of children, parents or families in order to reduce the risk or ameliorate the effect of less than optimal social and physical environments. This paper focuses on two types of parenting support programs: parenting programs - short-term interventions aimed at helping parents improve their relationship with their child;  home visiting programs - which include various programs, supports and services delivered to the family by a person visiting the home

Estimating Sensor Motion from Wide-Field Optical Flow on a Log-Dipolar Sensor

Log-polar image architectures, motivated by the structure of the human visual field, have long been investigated in computer vision for use in estimating motion parameters from an optical flow vector field. Practical problems with this approach have been: (i) dependence on assumed alignment of the visual and motion axes; (ii) sensitivity to occlusion form moving and stationary objects in the central visual field, where much of the numerical sensitivity is concentrated; and (iii) inaccuracy of the log-polar architecture (which is an approximation to the central 20°) for wide-field biological vision. In the present paper, we show that an algorithm based on generalization of the log-polar architecture; termed the log-dipolar sensor, provides a large improvement in performance relative to the usual log-polar sampling. Specifically, our algorithm: (i) is tolerant of large misalignmnet of the optical and motion axes; (ii) is insensitive to significant occlusion by objects of unknown motion; and (iii) represents a more correct analogy to the wide-field structure of human vision. Using the Helmholtz-Hodge decomposition to estimate the optical flow vector field on a log-dipolar sensor, we demonstrate these advantages, using synthetic optical flow maps as well as natural image sequences

Urban Sprawl: Scenario Analyses For Public Policy - Makers

This paper examines the likely effects of public-policy on residential development in the Wappinger Creek Watershed within Dutchess County in the Hudson River Valley of New York State.  An econometric model is used in combination with Monte Carlo simulation to project residential development in a spatial format using a Geographic Information System (GIS).  GIS was used to extract data with bio-geophysical attributes, such as slope, soil, and location characteristics, to project growth trends for residential use of undeveloped land parcels due to changes in public policy.  Detailed scenarios present stakeholders the economic, social, and environmental implications of a possible course of action.  The results indicate that public-policy can be effectively used to counteract the effects of urban sprawl and increased population

Exact Geosedics and Shortest Paths on Polyhedral Surface

We present two algorithms for computing distances along a non-convex polyhedral surface. The first algorithm computes exact minimal-geodesic distances and the second algorithm combines these distances to compute exact shortest-path distances along the surface. Both algorithms have been extended to compute the exact minimalgeodesic paths and shortest paths. These algorithms have been implemented and validated on surfaces for which the correct solutions are known, in order to verify the accuracy and to measure the run-time performance, which is cubic or less for each algorithm. The exact-distance computations carried out by these algorithms are feasible for large-scale surfaces containing tens of thousands of vertices, and are a necessary component of near-isometric surface flattening methods that accurately transform curved manifolds into flat representations.National Institute for Biomedical Imaging and Bioengineering (R01 EB001550

I volgari municipali e l'affioramento di una scripta nel medioevo lombardo

L'articolo si propone di motivare come nella storia linguistica delle città lombarde lingua/ dialetto non siano sistemi contrapposti, ma registri strettamente legati. Le indicazioni manzoniane in apertura invitano a osservare gli statuti cittadini del medioevo come luogo di contatto e di scambio tra due sistemi linguistici, latino e volgare. Senza varcare di proposito la soglia di alcuni dei più antichi manoscritti lombardi, l'articolo cerca di rilevare nelle testimonianze dell'originaria diglossia una ben più complessa sintonia di affioramenti e di successivi strappi, osservando nella lente della scrittura un passaggio di testimone, quello tra latino e volgare, che le opposizioni scolastiche al pari dei facili fraintendimenti terminologici non aiutano a sciogliere.The article aims at assessing the motives for which, in the linguistic history of the Lombardian cities, lingua/dialetto (language/dialect) are not contraposed systems, but are instead highly interlinked registers. The Manzonian information given at the beginning of the article invites us to consider the medieval city statutes as a point of contact and exchange between two linguistic systems, Latin and the vulgate. Without expressly crossing the threshold of some of the oldest Lombardian manuscripts, the article attempts to underline, within the evidence provided by the original digloss, a complex awareness both of growth and of successive breakings, observing, through the lens of writing, a passage of testimony between Latin and the vulgate, which scholastic opposition, just as with facile terminological misunderstandings, does not help to clarify

Labor Migration And Rural-Suburban Symbiosis In Igbo Society

Two southeastern Nigerian villages were surveyed to study labor force migration in a traditional African society. A binary logit model was used to examine paid work differences between males and females in both Umuluwe (the ancestors’ village) and Obigbo (a suburban village) and paid work differences between the residents in the two villages. The results show a strong correlation between education and employment; and between education and the likelihood of migration to Obigbo. We found that each village plays its own symbiotic part in terms of economic activity, life stages of the villagers, and gender roles

A review on the prevention of inflammatory periimplant diseases

Background: An impressive number of dental implants are inserted worldwide. Evolution in dental implants and simplification of surgical techniques allowed a significant increase in the number of dentists involved in implant surgery. Most of them are general dentists, are not always sufficiently formed and experienced, frequently use low-quality implants, do not adopt the proper patient selective criteria, do not adequately monitor and maintain the inserted implants, and do not report their own statistics to the dental community. Consequently, the incidence of inflammatory periimplant diseases (IPDs) has progressively increased to values significantly higher than those previously indicated by the scientific literature. Materials and Methods: Two main literature searches were undertaken in October 2018 in the PubMed Website database. Only articles written in English and published from 2008 onward were considered; 'Clinical Trial,' 'Meta analysis,' 'Observational study,' 'Review,' and 'Validation study' were selected as article type filters. The following keywords were used in the searches: 'Peri implantitis prevention' and 'Dental implant failure prevention.'Results: Preventive measures are analyzed according to the different factors that can favor the occurrence of an infection. The factors are divided into (i) implant dependent, (ii) patient dependent, and (iii) surgeon dependent. Conclusions: Scientific and clinical data confirm that when materials are selected with care, patients are carefully evaluated for factors of risk and attitude to adhere to the necessary maintenance program, and operative protocols and maintenance programs are respected dental implants can be attractive and effective tools for oral rehabilitation. Nevertheless, dentists and patients should have greater awareness that in many cases the decision to utilize dental implants cannot be taken lightly
