description: USDA’s child nutrition programs (National School Lunch Program, School Breakfast Program, Summer Food Service Program, and Child and Adult Care Food Program) have as goals to improve food security and provide children with a regular source of nutritious meals. In this report, we present updated statistics on food insecurity among school-age children from the Food Security Supplement to the Current Population Survey for 2014 and 2015. We then summarize recent research on the effects of child nutrition programs on children’s food security and diets and discuss recent developments in nutrition assistance for school-age children. Studies that account for the greater likelihood of participation in these programs among children from food-insecure households find that school meal programs reduce food insecurity among children. Child nutrition programs also contribute to diet quality and academic performance for children from low-income and food-insecure households.

description: We revisit the Bogoliubov theory of quantum droplets proposed by Petrov {[}Phys. Rev. Lett. \textbf{115}, 155302 (2015){]} for an ultracold Bose-Bose mixture, where the mean-field collapse is stabilized by the Lee-Huang-Yang quantum fluctuations. We show that a loophole in Petrov's theory, i.e., the ignorance of the softening complex Bogoliubov spectrum, can be naturally removed by the introduction of bosonic pairing. The pairing leads to weaker mean-field attractions, and also stronger Lee-Huang-Yang term in the case of unequal intraspecies interactions. As a result, the equilibrium density for the formation of self-bound droplets significantly decrease in the deep droplet regime, in agreement with a recent observation from diffusion Monte Carlo simulations. Our construction of a consistent Bogoliubov theory paves the way to understand the puzzling low critical number of small quantum droplets observed in the experiment {[}Science \textbf{359}, 301 (2018){]}.

Um die Lektionen optimal den Kompetenzen der heterogenen Gruppe anzupassen und die Teilhabe aller zu gewährleisten, dient mir das „Handlungsmodell inklusiver Sportunterricht“ nach Heike Tiemann (2015) als Vorbereitung. Während der Sportstunden versuche ich folgende Dimensionen zu erfassen:
 •! Emotionale Ebene (Freude am Sportunterricht)
 •! Soziale Ebene (Integrationserlebnis)
 •! Leistungsebene (Bewertung körperliche Anstrengung)
 Mit der Methode des standardisierten Interviews sowie mit Pulsmessgeräten evaluiere ich die Sportlektionen. Einen gesamthaften Eindruck über das Projekt gewinne ich mit Leitfadeninterviews, welche mit projektbeteiligten Schülerinnen und Schüler sowie einer Heilpädagogin und einem Heilpädagogen im Anschluss an die Sportlektionen geführt werden.

Subjects: subject: Unawareness

subject: Screening
subject: Limited Liability

description: We analyze a moral hazard problem with unaware agents and limited liability. A fraction of agents is unaware of their effort choice and chooses a default effort instead. The principal cannot observe whether an agent is unaware or not. He thus wants to screen the agents using a menu of contracts. Furthermore, the principal has the option to make all agents aware of their effort choice. The first paper treats the case of a monopolist principal. We show that under monopoly unawareness is self-reinforcing and contrast the results under limited liability with those under risk aversion. In the limited liability case, unaware agents can receive a rent and aware agents may loose from the presence of unaware agents. The second paper studies competing principals. Under competition, the share of unaware agents does not affect the equilibrium outcome. Agents are made aware even if this decreases total output. Thus, competition between principals can decrease efficiency.

Subjects: subject: New Keynesian model

description: Empirical studies have documented the presence of asymmetric effects of monetary policy. For example, some studies show that the magnitude of the response of output to different types of shocks depends on whether the economy is in recession or expansion or whether the shock is negative or positive (Garcia and Schaller, 1999). In this paper I use a theoretical model capable of capturing asymmetric effects of monetary policy found in real data. I use a standard New Keynesian model and impose the Zero Lower Bound (ZLB) constraint on the nominal interest rate. The presence of the ZLB constraint leads to a kink in the solution of the model. As a re- sult the standard approximation technique in the literature (the projection method with the Chebyshev polynomials) is not reliable. To deal with the kink problem in the policy function of the nominal interest rate I employ the projection method with the spline polynomials. To preserve nonlinear- ities of the model and reveal possible asymmetries I obtain fully nonlinear solution. As a preliminary step there is an overview of the related litera- ture as well as empirical analysis of the U.S. data using a Markov-switching model.

description: Heart failure (HF) is typically managed using both medical and patient self-management interventions. Individuals with HF often have frequent readmissions to hospital for medical management. Effective self-management can help to reduce the exacerbation of HF symptoms and the frequency of readmissions. A scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review (PRISMA-ScR) guidelines was conducted to identify literature on the interventions used by allied health professionals to promote HF self-management. A search strategy was implemented, and articles were reviewed by two independent reviewers. Twenty articles met the inclusion criteria. Articles included interventions from physical therapy, nutrition, social work, and occupational therapy, as well as other health professions in team-based programs. The most common interventions were verbal education, textual information, monitoring resources, and skills practice. Interventions addressed diet/fluid control, exercise and activity, symptom monitoring, medication management, cardiovascular disease knowledge, and mental health. Many interventions were theory informed. There is nascent evidence that interventions promoting HF self-management positively impact health and quality of life outcomes. HF self-management is multi-faceted and requires interprofessional collaboration. Further work is warranted exploring the impact of theory-informed interventions, and the effectiveness of interventions on self-management competence and desired health outcomes. Verbal education, printed information, monitoring documents/systems, and skills practice were the most common intervention modalities to promote heart failure self-management.Self-management interventions address diet/fluid control, exercise and activity, symptom monitoring, medication management, cardiovascular disease knowledge, and mental health aspects of heart failure.There is indicative evidence that interventions promoting heart failure self-management lead to increased health and quality of life outcomes.An interprofessional collaborative practice approach is important given that heart failure self-management is multi-faceted.

Subjects: subject: United States, balance of payments, dollar, exchange rate adjustment, controls
subject: F32, E42

description: In the last two years the U.S. balance of payments and the international position of the dollar have undergone sharp and somewhat paradoxical changes. Despite the unprecedented deterioration of the external balance in 1969, the dollar was left entirely unscathed in the exchange market. The article considers this paradox, the dollar’s position as the world’s foremost reserve currency and flexibility with regards to exchange rate adjustment. The author argues that the real choice is not between fixed exchange rates and some sort of flexibility, but rather between a messy and disorderly method of changing exchange rates that entails crisis, speculation and controls, and a smooth adjustment which largely avoids controls and reduces speculation to a minimum.

description: The economic factors that determine the differential level of variance of rent paid per pound of allotment transferred were analyzed in the framework of cost and returns to information. Regression analysis was used to test the hypothesis, that the variance in rent paid within a county for the 1966 production year was affected by the cost of information, returns to information and the level of variance existing before the search of market processes. The data used to study these hypotheses were obtained by a mail survey in 15 counties in North Carolina and from the ASCS county offices. Two basic models were developed. In the first one the dependent variable was an estimate of the total variance of rent paid in a county. In the second model the dependent variable was the variance due to differences among farmers within a county. The variable representing the cost of information hypothesis was found to be a significant factor in explaining the level of variance in the second model. The variable representing the returns to information hypothesis was significant in the first model. The "percentage of underplanting in 1961" was used as the independent variable representing the hypothesis that variance existing before the search of the market affects the variance in rent paid. Its coefficient was significant in both models. Transferability of information was expected to result in the reduction of variance as the trading season advances. Regressions of variance of rent paid by 15-day intervals on the time variable indicated no trend in the level by variance within each comty. The effect of large poundage, transferred by each farmer, on the price paid by him was investigated. A negative effect was hypothesized, but the regression coefficient had the hypothesized sign in only a few of the sample counties.
Automatismo o discrezionalità nella politica monetaria?

Subjects: subject: Monetary policy, Friedman, money supply, price stabilisation, automation, income velocity
subject: E52, E51

description: It is generally excepted that changes in the money supply exert a profound influence on the economic process. The same goes for the resulting conclusion that the creation of money cannot be left to private initiative. These two propositions pose the questions: (a) what will be the economic effects of a given change in the money supply? (b) how has the money supply to be manipulated, if a specific aim is to be achieved? The present paper deals with the latter of these two questions. The author criticises Milton Friedman’s rule for the regulation of money supply aimed at price stabilisation in which matters are no longer left to the central bank’s discretion but are governed by a process of automation. This rule is based on the assumption of a constant or approximately constant income velocity which, according to the author, is not confirmed by the facts. It is argued that Milton’s conclusions are derived from statistical findings alone, however, the closest correlation between variables can explain nothing about causal relations between the variables or changes of variables.

description: In this paper I analyze numerically and quantitatively a model of labor search with unemployment insurance, voluntary quits and various labor attachment requirements. In particular, I study welfare consequences of unemployment insurance design where workers who quit their jobs voluntarily are entitled to benefits. A simulation of the model calibrated to the US labor market shows that there are possible welfare gains associated with pursuing optimal re-entitlement policy for workers quitting their jobs voluntarily as compared to the actual policy employed in the US. By inducing monetary search costs and different unemployment benefit eligibility requirements, the model provides an explanation for empirical observations about differences in unemployment rate and income inequality between the US and European labor markets.
title: 'They can because they think they can?' : the education of pupils at two secondary schools for the blind, 1920-58
Creators: name: Normanton Erry, Jeanette Margaret
Publisher: name: The Open University
Year: 2011

description: Blind children were one of the first 'disabled' groups to be given an education by the State. However, for most children with a visual impairment, this schooling was only at an elementary level. This study looks at how pupils at Worcester College for the Blind and Chorleywood College for girls with little or no sight came to have the opportunity to receive the academic education which could provide them with access to the universities and professions. This is discussed in the context of the political and social environment of the period between 1920 and 1958, with an assessment of the continuities and changes.

The purpose of the study is to examine the complexity of factors which influenced the education of visually impaired children. No one explanation, either based on social control or progressive humanitarianism, can determine the development of special education. Class and gender as well as perceptions of 'disability' did playa role. The aim is then to judge the level to which the resultant education was enabling in terms of providing educational opportunities which could lead students towards active Citizenship and fulfilling employment. The study triangulates sources written from above by Government, charities and the governing bodies with school records as well as interviews and written accounts to give a voice to the former students.

In this thesis, variations in the experience of children with different impairments are examined alongside the level of influence possessed by blind people themselves. The nature of the education provided challenged the perceptions of society in some ways, while not attempting to confront the inequalities which existed in the mid-twentieth century. This resulted in a schooling which was enabling in its academic nature, but, while not disabling, left students unprepared for some of the skills required for adult life.

description: Labor market polarization is an ongoing structural change of the U.S. labor market which consists of the \hollowing out" of the wage and skill distribution. This paper examines the effects of this process on individ- ual workers, focusing on the feedback effect from the changes in the labor market aggregates represented by employment-to-population ratios and by the employment shares of the different occupational groups on the transi- tion between unemployment and the three main occupational groups. The main occupational groups defined by skill and wage levels are the routine, non-routine manual and non-routine cognitive occupations. In order to estimate the effects of the aggregates on the individual level, transition probabilities are estimated with logistic regressions. The 1991 and the 2001 panels of the Survey of Income and Program Participation are used as data source for the analysis, in contrast to most of the literature which uses CPS data. The findings show that polarization was present in the pe- riod of the 2001 panel, while it cannot be detected in the 1991 panel. The results suggest that, as expected, the aggregate rates had an effect on the transition toward unemployment in both panels, but they did not in uence the movement between the routine, non-routine cognitive and non-routine occupational groups. The results also imply that in the 2001 panel the probability of acquiring a routine job after job change is smaller for those who were employed in any occupational category than for those who were unemployed before the change. This indicates that on the level of individ- uals the polarization made the direct transition from any job towards the routine occupations more difficult.

Subjects: subject: Less developed countries, unemployment, lagged employment, development
subject: E24, O11

description: One of the most perplexing - and serious - problems now confronting many of the less developed countries is their growing level of urban unemployment. A number of studies have emphasized the broad dimensions of the problem: industrial employment has lagged behind growth in industrial output, behind growth of the urban population, and even behind the general growth rate of population. The evidence suggests that the Keynesian theory of unemployment does not fit these countries. Even more, it indicates that development plans have failed to achieve their objective of providing a substantial growth of employment opportunities in the modern industrial urban sector. The present work examines the major reasons why development plans have generally been unsuccessful in solving the unemployment problem, before considering possible correctives for the situation of increasing unemployment.

description: Because of the wide-spread and devastating effects of malaria in sub- Saharan Africa, the U.S. launched a $1.2 billion initiative to rapidly scale- up malaria prevention and treatment interventions in high-burden coun- tries in sub-Saharan Africa through the President's Malaria Initiative. One of the main mechanisms used to reduce child mortality due to malaria is the free and heavily subsidized distribution of insecticide-treated bed nets (ITNs). This paper evaluates the effect of such campaigns in Rwanda, Senegal, Uganda, and Zimbabwe using an estimator that exploits the fact that the intervention only affects mortality through a behaviour change from not using ITNs to using ITNs. I find that Rwanda sees a significant decrease in mortality for children under two years of age, but that no ef- fect can be seen for Senegal, Uganda, and Zimbabwe. Through a series of plausibility and falsification tests, I find that the estimators for all coun- tries except Zimbabwe fulfil the assumptions of the model. Therefore, no decrease in mortality for children under two can be seen from these ITN interventions in Uganda and Senegal. A decrease of 7.9 deaths in children under three per 1,000 live births per year is reported for Rwanda.

description: The purpose of this study was to determine functional coefficients which relate per-acre labor costs of producing flue-cured tobacco to certain production variables. Closely-supervised controlled experiments on farms in 1963 through 1965 were employed to develop the data. Multiple regression analysis was used to determine the relationships between plants, leaves, pounds and suckers and labor. Best estimates of labor requirements generally were obtained using plants, leaves or suckers as explanatory variables as opposed to using pounds. Relationships were found to be linear, and the slope coefficients were uniform among years, locations and stalk positions. Procedures are outlined in the publication for using the coefficients to estimate actual labor costs for alternative combinations of cultural practices.

description: In this report techniques for looking at the export demand for three U. S. agricultural products are brought together and summarized. The products are flue-cured tobacco, wheat and cotton. The unifying theme is that analyzing substitution relations and market share relations avoids the pitfalls that have plagued earlier attempts to derive statistical estimates in international trade. Similarly, combining cross section and time series data for direct estimation also provides estimates that are free of the previously encountered statistical problems.

description: In the current network-based computing world, where the number of interconnected devices grows exponentially, their diversity, malfunctions, and cybersecurity threats are increasing at the same rate. To guarantee the correct functioning and performance of novel environments such as Smart Cities, Industry 4.0, or crowdsensing, it is crucial to identify the capabilities of their devices (e.g., sensors, actuators) and detect potential misbehavior that may arise due to cyberattacks, system faults, or misconfigurations. With this goal in mind, a promising research field emerged focusing on creating and managing fingerprints that model the behavior of both the device actions and its components. The article at hand studies the recent growth of the device behavior fingerprinting field in terms of application scenarios, behavioral sources, and processing and evaluation techniques. First, it performs a comprehensive review of the device types, behavioral data, and processing and evaluation techniques used by the most recent and representative research works dealing with two major scenarios: device identification and device misbehavior detection. After that, each work is deeply analyzed and compared, emphasizing its characteristics, advantages, and limitations. This article also provides researchers with a review of the most relevant characteristics of existing datasets as most of the novel processing techniques are based on machine learning and deep learning. Finally, it studies the evolution of these two scenarios in recent years, providing lessons learned, current trends, and future research challenges to guide new solutions in the area.

description: The most profitable harvesting and curing system for flue-cured tobacco and the amount of farm labor required for various wage rates for hired labor were analyzed in this study. Labor use was estimated both for individual farms and for the study area. Data were collected in Census Subregion 17, North Carolina, to describe four farm situations and eight alternative harvesting-curing systems for tobacco that represented a wide range of capital-labor ratios. The most profitable harvesting-curing systems were determined for each farm situation for wage rates for hired labor varying from 1967 levels to a maximum of $4.00 per hour. The analysis was conducted for two lengths of run. In the short run, adequate conventional curing barns were assumed to be present on the farms. In the long run, all curing facilities were assumed to be variable. At 1967 wage rates, the results were the same for both lengths of run for each farm. At higher wages some differences in results for the two lengths of run were noted. Substitution of several alternative systems for the most profitable system had little effect on net revenue in many cases. The impact of the adoption of the mechanical harvesting, bulk curing system on labor use in the study area was estimated. With complete adoption the quantity of labor could be reduced 40 percent. The time period estimated for adoption of this system by 91 percent of the farmers varied from 15 to 60.5 years from 1967 depending upon the lag and the harvester price assumed. If farm numbers continue to decline at the present rate, farm size could be sufficiently large for mechanical harvesters to be profitable. Also, if the reduction in the number of farm workers continues at the same rate, the impact of adoption on the labor market may be slight.

In contrast to previous works on EIT, we calculate the output state of the resultant slowly propagating light field while taking into account the effects of ground state dephasing and atomic noise for a more realistic model. In particular, we propose two experiments using slow light with a nonclassical probe field and show that two properties of the probe, entanglement and squeezing, characterizing the quantum state of the probe field, can be well-preserved throughout the passage.

description: Therapeutic group interventions are commonly provided in acquired brain injury (ABI) inpatient rehabilitation settings, but little is known about the extent of therapeutic groups run for community-dwellers with ABI. This paper seeks to review current literature concerning the nature of therapeutic groups run for community-dwellers with ABI and the involvement of occupational therapists. A scoping review was conducted with systematic searching of relevant databases guided by Arksey and O’Malley’s framework. Studies were included if they reported on therapeutic groups for community-dwellers with ABI. Articles were collated and summarised with key findings presented in narrative form with accompanying tables. Seventy articles met inclusion. Groups are used as therapeutic change agents for community-dwellers with ABI and target a diverse range of participation barriers. Participants valued group programs that established safe environments, a sense of belonging, growth opportunities and social connections. Group accessibility needs to be improved, with better funding avenues available for service providers, as well as greater consumer involvement in group design and facilitation. Groups are a valuable therapeutic modality supporting community-dwellers with ABI. Further research is warranted into the use of groups by occupational therapists working with community-dwellers with ABI. Therapeutic groups can support the development of social connections, community participation and help community-dwellers with ABI re-establish a positive self-identity.Conducting groups in community settings and involving consumers in group design and facilitation may enhance the group experience for participants.Occupational Therapists should be involved in the design and delivery of occupation-based and participation focused group-based programs.

description: A typical assumption in the auction literature is that bidders can submit any bid within the non-negative part of the real line. Yet, when auctions are used the set of bids is restricted at least to a countably infinite set due to the discrete nature of currency, and often even to a finite set. We study the effects of explicitly modeling a restricted set of allowed bids in a Vickrey auction within the independent values framework. We present a characterization of all pure strategy equilibria of the unrestricted Vickrey auction, obtained by Blume and Heidhues (2004), and analyze how this set changes when we restrict ourselves to the Vickrey auction with a restricted set of bids, although we do not provide a complete description of this set. We discuss the consequences of the change of the equilibria on the seller's revenue and the consequences of a set of equilibria that is present in both models. We examine a tool that is available for the auctioneer to obtain a positive ex- pected revenue, namely a proper specification ex-ante of a dictatorial tie-breaking rule. We also explore the consequences of introducing of a reservation price in our setup, knowing that it yields a unique equilibrium in the non-restricted allowed bids case, as shown by Blume and Heidhues (2001). Finally, we summarize our contributions and provide a list of the several questions that remain open in the field.

description: When a gamma or cosmic ray strikes the top of Earth's atmosphere, a shower of secondary particles moves toward the surface. Some of these secondary particles are charged muons that subsequently enter Water Cherenkov Detectors (WCDs) on the ground. Many of these muons, traveling near the speed of light in vacuum, are moving faster than the speed of light in water and so trigger isotropic Cherenkov radiation in the WCDs. Inside many WCDs are photomultiplier tubes (PMTs) that detect this Cherenkov radiation. When the radial component of the speed of a muon toward a PMT drops from superluminal to subluminal, the PMT will record Cherenkov light from a little-known optical phenomenon called Relativistic Image Doubling (RID). Were the RID-detecting PMTs replaced by high resolution video recorders, they would see two Cherenkov images of the muon suddenly appear inside the tank, with one image moving with a velocity component toward the recorders, the other away. Even without a video, the RID phenomenon will cause different PMTs to record markedly different light curves for the same muon. In this paper, we present a study hoping to inspire the explicit detection and reporting of RID effects in WCDs. We consider three example cases of muon RIDs in High-Altitude Water Cherenkov (HAWC)-like systems: vertical, horizontal and oblique. Monte Carlo simulations show that RID effects in HAWC-like systems are not rare -- they occur for over 85 percent of all muon tracks.

title: Harvesting online ontologies for ontology evolution

description: Ontologies need to evolve to keep their domain representation adequate. However, the process of identifying new domain changes, and applying them to the ontology is tedious and time-consuming.

 Our hypothesis is that online ontologies can provide background knowledge to decrease user efforts during ontology evolution, by integrating new domain concepts through automated relation discovery and relevance assessment techniques, while resulting in ontologies of similar qualities to when the ontology engineers' knowledge is solely used.

 We propose, implement and evaluate solutions that exploit the conceptual connections and structure of online ontologies to first, automatically suggest new additions to the ontology in the form of concepts derived from domain data, and their corresponding connections to existing elements in the ontology; and second, to automatically evaluate the proposed changes in terms of relevance with respect to the ontology under evolution, by relying on a novel pattern-based technique for relevance assessment. We also present in this thesis various experiments to test the feasibility of each proposed approach separately, in addition to an overall evaluation that validates our hypothesis that user time during evolution is indeed decreased through the use of online ontologies, with comparable results to a fully manual ontology evolution.

description: The major purpose of this study was to quantify factors affecting the total cost of harvesting, curing and market preparation of flue-cured tobacco. Data were obtained from seventeen farmers located in eight Eastern North Carolina counties during the summers of 1968-69. Labor usage, fuel and electricity usage were quantified for eight alternative harvesting systems, all of which utilized bulk curing systems. Labor requirements per 100 pounds of cured tobacco were inversely related to stalk position;..!_.~., lower stalk position had higher labor usage per 100 pounds. The walking-field racking system used significantly less labor than any other system and this difference ranged from .41 to 4.83 man-hours per 100 pounds for the mechanical-barn racking and riding-barn racking systems, respectively. Initial and annual overhead costs were computed for these eight systems for operations varying from 3 to 40 acres harvested annually. Wage rates were varied from $1.30 to $3.00 per hour in this analysis. Three mechanical harvesting systems were added to the observed systems to evaluate the feasibility of mechanical harvesters with increased initial costs and reduced labor requirements. At an $11,000 initial cost for the harvester, with a 50 percent reduction in labor usage to 2.00 man-hours per 100 pounds, a break-even wage of $3.36 per hour exists between the walking-field racking system and the mechanical harvesting-barn racking system at 25 acres harvested annually and a $2.07 per hour break-even wage rate at 40 acres harvested annually. With initial cost of harvesters approaching $15,000 each, a considerable increase above 1971 levels in wage rates will be necessary to economically justify the adoption of mechanical harvesting equipment.
Fractures in perspectives on good student writing

description: While university students are expected to be good academic writers, there is little consensus on what constitutes good writing. The purpose of this study was to document fractures in instructors' and students' perspectives on good academic writing by surveying 157 instructors and 523 students about first-year writing at the University of British Columbia. The survey instrument consisted of a four-part questionnaire. The author used three composition pedagogies (Current Traditional Rhetoric, Expressivism and Social Construction) to ascertain how instructors and students ranked and graded three sample paragraphs of first-year student writing and assessed the importance of 45 writing attributes. Respondents' scores of the 45 attributes were aggregated into seven attribute families (Mechanics, Author's Voice, Social Analysis, Paragraph Structure, Academic Inquiry, Figurative Language and Academic Conventions). The author also measured the extent to which assessments of good writing were shaped by faculty's world views and personal characteristics, or their academic situations. Of the 14 measures used (three ranking options, three grading options, and assessments of importance of seven attribute families and combined attributes), there were nine fractures dividing instructors from students. The biggest involved Academic Inquiry (which instructors favoured), Social Analysis and Author's Voice (both of which students favoured). There was no consensus among instructors. All three paragraphs received a wide range of grades. Every paragraph was ranked top, middle or bottom with no majority opinion for any one paragraph about how best to write. Of the 14 measures, there were six fractures between instructor operations (paragraph ranking and grading) and preferences (importance of different writing attributes). Situational variables had more influence on instructors' paragraph assessments while personological characteristics were more predictive of the importance they assigned writing attributes. Instructors were most divided by employment status and world view. They were also divided by gender, country of birth and first language. Fractures in perspectives on good writing divide instructors from students as well as faculty themselves. Centralized Writing Departments that use a three-pronged research/pedagogical/administrative approach should therefore be established to investigate fracture points; navigate students through such fractures; and provide writing researchers, instructors, and program planners administrative and funding support.

description: Regression analysis was used to estimate the relationship between quantities of quota and rental rates and between labor use, wages and quota for North Carolina for the years 1966 through 1969 and for each of the other flue-cured tobacco producing states for the years 1966 through 1968. The impact of probable changes in aggregate quota and the wage rate of hired labor on rental rates within counties was estimated using regression coefficients. The estimated reservation demand curves for county quota markets were used to project transfers of quota between counties which might occur if wider transferability was allowed. The rental rate which might prevail within the state under various transfer rules was also estimated. In no case did the estimates vary greatly from average observed rental rates. Large quantities of quota were projected to move from the Old and Middle Belts to the Eastern and Border Belts. Estimates of the transfers across state boundaries under various program rules were also made. The impact of the hypothetical transfers across county lines on the efficiency of production and the distribution of income was also estimated. While aggregate gains within North Carolina could be substantial, producers in high-rent counties and owners in low-rent counties would gain while producers in low-rent counties and owners in high-rent counties would lose from the initiation of a statewide quota transfer program.

description: The article presents a study on the least-squares construction of the yield curves for Italian government securities from 1957 to 1967. The author provides a general introduction to the Italian financial system and the initial results, before considering the technical aspects. In the first section of the paper a brief outline of the Italian bond market is provided, so as to give the reader a brief knowledge of the institutional system in Italy. The main features of the estimated yield curves are then detailed and some implications of the data are considered with regard to recent attempts of the monetary authorities to prevent the increase in interest rates. Some general considerations are made before the free-hand interpolation of Durand’s “basic yields” and the U.S. treasury securities curves is considered. The linear interpolation of Grant’s British government securities yield curves is then assessed. Finally, the method for least-squares interpolation is explained before the regression model used for Italian B.T.P. and the resulting estimated yield curves are presented. JEL: G12, H63, E43
