The Effect of Shocks on Household Consumption in Rural Nigeria

Farm households in rural areas of Nigeria are naturally prone to various forms of idiosyncratic and covariate shocks. The frequent occurrence of shocks among the households coupled with lack of effective shock coping mechanisms in the region has made the households vulnerable to poverty. Idiosyncratic shocks affects only an individual household, for example illness or death of a household member. On the other hand, covariate shocks impinge an impact on a larger group of population in the same area at the same time, for instance adverse weather condition. In the absence of functioning formal coping mechanisms, the households resort to borrowing, adjustment in food intake, sale of goods or removing children from formal school. However, little is known about the impact of shocks on household consumption. To contribute to literature, this paper used the nationally representative survey data of rural farm household in Nigeria to empirically examine the effect of both idiosyncratic and covariate shocks on their consumption expenditure, using ordinary least square method. The least square method deemed to be appropriate for the analysis because of the exogeneity nature of shocks to consumption. In contrast to the existing works, the study measures shock as a continuous variable and also disaggregated the sample into and non-poor households on the basis of world poverty line of $ 1.20 per day with a view to recommend possible social protection measures to cope with adverse effect of shocks on household consumption. The framework of the study was developed from Permanent income hypothesis which postulates that any transitory changes in income will not have no any effect on permanent income and hence on actual consumption. The result of the ordinary least square regression used in the analysis revealed that whilst idiosyncratic and climatic shocks have no significant effect on household consumption, price shock is having a significant negative impact on household consumption. Further, the result of disaggregated sample suggests that that the non-poor households are able to adequately insure against the effect of idiosyncratic shocks as well as the climatic shock on their consumption while the poorer ones had not been able to insure against the effect of shocks related to death, livestock loss, climate change and price changes on their consumption. This implies that both poor and non-poor farm households should be provided with an adequate and effective social protection measures that would mitigate the effect of shocks on their consumption and welfare.
Sub-Dominant Oscillation Effects in Atmospheric Neutrino Experiments 101 Flux Calculation in HKKM

The calculation of atmospheric neutrino flux in HKKM04 [1] is over viewed. There are many improvements from HKKM95 [2]; the primary flux model is replaced by the one based on the AMS [3] and BESS [4] observations, and the interaction model is changed to DPMJET-III [5]. Also the calculation is carried out in a full 3-dimensional scheme. However, the differences between 3D and 1D calculations are not seen in the averaged fluxes over the azimuthal angles for > ∼ 3 GeV.
Insider Ownership Structure and Firm Performance: A Productivity Perspective Study in Taiwan's Electronics Industry

In the context of agency theory (Jensen and Meckling, 1976. "Journal of Financial Economics", 3, 305-360), how insider stock ownership relates to firm performance is explored in this paper. The relevant performance measure used is total factor productivity. Insiders are classified into executives, board members and blockholders so as to facilitate a detailed study. Five-year (1996-2000) panel data of 333 Taiwanese listed electronics firms are examined. It is observed that total insider ownership remains steady while the executive-to-insider holding ratio increases significantly. In terms of the effect on total factor productivity, neither the total insider ownership nor the board-to-insider holding ratio shows any influence on productivity. However, productivity first decreases then increases with the executive-to-insider holding ratio, forming a U-shaped relationship. The results indicate that stock ownership of top officers in high-tech firms should be encouraged to enhance productivity. Copyright Blackwell Publishing Ltd 2005.
Visuospatial abilities in normal and pathological aging: Cognitive processes and neuroimaging correlates

The ﬁeld of spatial cognition has been evolving rapidly over the last few years, driven by convergence of results from both basic and clinical research. Spatial ability is involved in many cognitive tasks typically performed in everyday life, so it is important to accurately define and assess spatial ability in the context of everyday life. Recent studies also suggest that spatial abilities decline with normal aging, but it is not yet clear which spatial components decline during normal age-related cognitive decline, which are preserved, and at what point the spatial deficits become severe enough to suggest MCI or another degenerative disease. The main goal of my research projects, developed in three studies, was to investigate different components of spatial ability in a population of healthy older people, in individuals affected by mild cognitive impairment, and in autopsy-verified patients with dementia, in order to (a) develop new, more ecological instruments for the assessment of spatial abilities, (b) verify whether the assessment of spatial abilities may help in discriminating between MCI and controls and be used as a marker of the onset of AD, and (c) be used in differential diagnosis between Alzheimer's Disease and Dementia with Lewy bodies. In Study 1, results confirm the a priori hypothesis, ascertaining the reliability of these new spatial tests in measuring different components of spatial abilities: object memory, simultaneous spatial memory and sequential spatial memory. In the second study, the discriminant analyses revealed an elevated discriminative power of the new spatial battery in identifying MCI. Neuroimaging findings showed that MCI patients present a higher level of cortical atrophy in memory-related regions and a different pattern of brain correlation between visuospatial abilities and grey matter values compared with healthy elderly controls. Finally, results of Study 3 suggest that disproportionately severe visuospatial deficits, which are known to be prevalent in DLB patients, also extend to visuoperceptual abilities that do not involve construction or motor manipulation. This deficit reflects primarily Lewy Body pathology and is not related to the degree of concomitant AD pathology. All of this evidence supports the main idea that visuospatial evaluation should have a greater role in normal and pathological aging, in understanding the daily life abilities of healthy older people, in completing the diagnostic process of MCI, and also helping in the differential diagnosis between different types of dementia.
Parasitism of host trees by the Loranthaceae in the region of Douala (Cameroon)

The Loranthaceae constitute the most important parasite plants that cause variable damages: morphological, technological, ecological and socio- economic. These numerous and damaging effects make some parasitic angiosperms true agronomic threats, especially in developing countries. The Loranthaceae is represented in Cameroon by 26 species gathered into 7 genus. The study area includes four sites: a traditional plantation of Cola nitida situated at Penja (70 km Nord of Douala), the main road to Douala airport, one quarter (Logbessou) and Makondo village (80 km East of Douala) in an orchard dominated by Citrus . A total of 2643 individuals of DBH (diameter at breast height) greater or equal to 5 cm were inventoried. 637 individuals were parasitized. Eight known species were identified. Phragmanthera capitata is more frequent and more abundant (76.14%). The infested host trees belong to 16 species gathered into 12 genus and 10 families. The most parasitized host family is Sterculiaceae . The most sensitive host species to the parasitism of Loranthaceae is P. americana (21.51%), followed by C. nitida (17.27%) and Terminalia mantaly (13.65%). Lauraceae is infested by 7 Loranthaceae out of 8 parasites investigated. The consequences of the parasitism of the Loranthaceae demonstrate the need for establishing comprehensive ecosystem management programs. Key words : Host trees, inventory, Loranthaceae , parasites plants.
Valuing the Visual Disamenity of Offshore Wind Projects at Varying Distances from the Shore

Several offshore wind power projects are under consideration in the United States. A concern with any such project is the visual disamenity it may create. Using a stated preference choice model, we estimated the external costs to residents of the state of Delaware for offshore wind turbines located at different distances from the coast. The annual costs to inland residents was $19, $9, $1, and $0 (2006 dollars) per household for turbines located at 0.9, 3.6, 6, and 9 miles offshore. The cost to residents living near the ocean was $80, $69, $35, and $27 per household for the same increments. (JEL Q42, Q51)
Determination of the DC Electrical Conductivity of Multiwalled Carbon Nanotube Films and Graphene Layers from Noncontact Time-Domain Terahertz Measurements

Measuring the DC conductivity of very thin films could be rather difficult because of the electrical contact issue. This DC conductivity can, however, be extracted from noncontact measurements at GHz and THz frequencies using elaborated conductivity models that nicely fit the experimental data. Here we employ this technique to study the DC conductivity of fragile nanometer-thick films of multiwalled carbon nanotubes and monolayer graphene. The THz response of the films is measured by THz time-domain spectroscopy. We show that the THz conductivity of the samples is well fitted by either Drude-Lorentz model or Drude-Smith model, giving information on the physics of electrical conductivity in these materials. This extraction procedure is validated by the good agreement between the so-obtained DC conductivity and the one measured with a classical 4-point probe in-line contact method.
The Financialization of Storable Commodities

I solve a dynamic equilibrium model of commodity spot and futures prices, incorporating an active futures market, heterogeneous risk-averse participants, and storage. When calibrated to data from the crude oil market, the model implies that financialization reduces the futures risk premium and increases correlation between futures open interest and the spot price level. However, there is no long-run increase in the mean spot price, and speculative storage generally attenuates financialization’s effect on spot price volatility. Therefore, financialization’s effect on spot price dynamics through storage arbitrage is likely modest, even if futures positions and risk premia are substantially altered.

DESIGN PROCESS VISUALIZING AND REVIEW SYSTEM WITH ARCHITECTURAL CONCEPT DESIGN ONTOLOGY

DesignScape, a prototype design process visualization and review system, is being developed. Its purpose is to visualize the design process in more intuitive manner so that one can get an insight to the complicated aspects of the design process. By providing a tangible utility to the design process performed by the expert designers or guided by the system, novice designers will be greatly helped to learn how to approach a certain class of design. Not only as an analysis tool to represent the characteristics of the design process, the system will be useful also for learning design process. A design ontology is being developed as a critical part of the system, to represent designer’s activities associated with various design information during the conceptual design process, and then to be utilized for a computer environment for design analysis and guidance. To develop the design ontology, a conceptual framework of design activity model is proposed, and then the model has been tested and elaborated through investigating the early phase of architectural design. A design process representation model is conceptualized based on the ontology, and reflected into the development of the system.
Large-Scale Forest Owner's Information Needs in Operational Planning of Timber Harvesting - Some Practical Views in Metsä- hallitus, Finnish State-Owned Enterprise

2011. Large-scale forest owner’s information needs in operational planning of timber harvesting – some practical views in Metsahallitus, Finnish state-owned enterprise. Silva Fennica 45(4): 711–727.Metsahallitus in Finland is a state enterprise that manages about 3.5 million hectares of pro-ductive commercial state-owned forest land. Metsahallitus has a forest management planning system which uses information stored in a GIS-based forest resource information system. The information on forest resources is currently collected using a standwise inventory system with ocular estimation of stand characteristics. New promising inventory methods based on laser scanning have been introduced. Before taking a new system into use, the information needs of Metsahallitus must be analysed. In this study, information needs in operational harvest planning have been analysed with a qualitative approach. A total of eight team leaders in the forestry business unit were interviewed, six of them representing the process responsible for the operational harvest planning and two representing the process responsible for the harvest and deliveries. Based on the study, two main decision making points with different information needs were confirmed. The first decision making point is related to finding the areas potential for immediate or near future harvesting. Here, geographical information on the need for the treatment as well as rough information on the harvestable volume is needed. In the second decision making point, a final decision of sites to be harvested is made with rather intensive field work. Precise delineations of the treatment are needed as well as good estimates of volumes of different timber assortments. When considering a new inventory system it is justified to consider how much of the information needs in these decision making points can be covered. Two different approaches are proposed for further analysis. The inter-views revealed a need for a more structured tactical planning system. Some of the findings of this study – especially the decision making points and information needs in them – may be transferable to other large-scale forest owners.
The inhomogeneous Landau equation with hard potentials

We consider weak solutions of the spatially inhomogeneous Landau equation with hard potentials ($\gamma \in (0,1]$), under the assumption that mass, energy, and entropy densities are under control. In this regime, with arbitrary initial data, we show that solutions satisfy pointwise Gaussian upper and lower bounds in the velocity variable. This is different from the behavior in the soft potentials case ($\gamma <0$), where Gaussian estimates are known not to hold without corresponding assumptions on the initial data. Our upper bounds imply weak solutions are $C^\infty$ in all three variables, and that continuation of solutions is governed only by the mass, energy, and entropy.

Sparse bridge estimation with a diverging number of parameters

The Bridge estimator with ν-penalty for some ν > 0 is one of the popular choices in penalized linear regression models. It is known that, when ν ≤ 1, the Bridge estimator produces sparse models which allow us to control the model complexity. However, when ν = 1, the Bridge estimator fails to identify the correct model since it requires certain strong sufficient conditions that are hard to hold in general, and when ν > 1, it achieves no sparsity in parameter estimation. In this paper, we propose the sparse Bridge estimator that is developed to find the correct sparse version of the Bridge estimator when ν ≥ 1. Theoretically, the sparse Bridge estimator is asymptotically equivalent to the oracle Bridge estimator when the number of predictive variables diverges to infinity but less than the sample size. Here, the oracle Bridge estimator is an ideal Bridge estimator obtained by deleting all irrelevant predictive variables in advance. Hence, the sparse Bridge estimator naturally inherits the properties of the Bridge estimator without losing correct model identification asymptotically. Numerical studies show that the sparse Bridge estimator can outperform other penalized estimators with a finite sample.
Parámetros genéticos para caractéres de crecimiento y reproductivos del ganado pardo suizo europeo de México

The aim of this study was to estimate the components of (co)variance and genetic parameters for birth weight (BW, n = 16 806), weaning weight adjusted to 240 d of age (WW240, n = 9 011), yearling weight (YW, n = 6 516), age at rst calving (AFC, n = 5 974) and calving interval (CI, n = 8 873) of Brown Swiss cattle from Mexico. Retrospective data from 1982 to 2010 were used from 86 ranches, spread across the country, which belonged to the Mexican Association of Registered Brown Swiss Cattle Breeders. Two trivariate analyzes were used considering BWWW240-YW and YW-AFC-CI traits. The animal model included the contemporary group, direct additive, maternal additive, permanent environmental e ects and the error term, plus age of cow at calving, parity and purebred degree as covariates. In general, direct heritabilities ranged from 0.03 to 0.35 and maternal heritabilities from 0.02 to 0.10. Correlations between direct and maternal additive genetic e ects for BW, WW240 and YW ranged from -0.29 to -0.70. The direct genetic correlations for BW-WW240, BW-YW and WW240-YW were 0.51, 0.44 and 0.84, respectively, whereas for YW-AFC, YW-CI and AFC-CI they were -0.34, 0.14 and -0.26, respectively. In conclusion, selection for yearling weight could reduce the age at rst calving without altering the calving interval.
HEAT TRANSFER IN CONFINED LAMINAR AXISYMMETRIC IMPINGING JETS AT SMALL NOZZLE-PLATE DISTANCES: THE ROLE OF UPSTREAM VORTICITY DIFFUSION

In laminar impinging flow heat transfer it is well known that at small nozzle-to-plate distances the Nusselt number distribution displays an off-stagnation point maxima located one nozzle radius away from the stagnation point. This article demonstrates that the occurrence of the off-stagnation point maxima is entirely a consequence of upstream flow development because of vorticity diffusion. It is not because of local acceleration of the mean radial flow as suggested in the existing literature. Numerical results are presented to analyze the variation in the peak-to-stagnation Nusselt number ratio as a function of the dimensionless nozzle-to-plate distance and the Reynolds and Prandtl numbers. The calculations correctly predict the disappearance of the off-stagnation point maxima at dimensionless nozzle-to-plate distances larger than 3/8.
Biochemical Clocks and Molecular Noise: Theoretical Study of Robustness Factors

We report a study of the influence of molecular fluctuations on a limit-cycle model of circadian rhythms based on the regulatory network of a gene involved in a biochemical clock. The molecular fluctuations may become important because of the low number of molecules involved in such genetic regulatory networks at the subcellular level. The molecular fluctuations are described by a birth-and-death stochastic process ruled by the chemical master equation of Nicolis and co-workers and simulated by Gillespie’s algorithm. The robustness of the oscillations is characterized, in particular, by the probability distribution of the first-return times and the autocorrelation functions of the noisy oscillations. The half-life of the autocorrelation functions is studied as a function of the size of the system which controls the magnitude of the molecular fluctuations and of the degree of cooperativity of some reaction steps of the biochemical clock. The role of the attractivity of the limit cycle is also discussed.
Correlations in low-dimensional quantum many-particle systems

This thesis concerns correlation effects in quantum many-particle systems in one and two dimensions. Such systems show many exotic nonFermi liquid phenomena, which can be treated analytically using nonperturbative field-theory methods. Quantum phase transitions between topologically ordered phases of matter, which do not break any symmetries, are studied. It is shown that although there is no local order parameter, a local measure from quantum information theory called reduced fidelity can detect such transitions. Entanglement in quantum impurity systems is also studied. The general expression for scaling corrections in entanglement entropy from boundary perturbations is derived within conformal field theory, showing that the asymptotic decay of Kondo screening clouds follow the same power-law as the impurity specific heat. Furthermore, the effects from spin-orbit interactions on Kondo physics in helical Luttinger liquids are studied. Such helical liquids occur on the edges of two-dimensional topological insulators. It is shown that Rashba and Dresselhaus interactions can potentially destroy Kondo singlet formation in such a system, and that the coupling to an electric field gives a mechanism to control transport properties. The most recent work focuses on correlations in interacting onedimensional Bose gases. The asymptotic expression for correlation functions in a generalized Gibbs ensemble, where all the local conservation laws appear, is obtained from Bethe Ansatz and conformal field theory. In addition to the research papers with the above results, the thesis also contains an introductory text reviewing background material.
