description: Background: The healthcare assessment of the Saudi population serves as a foundational step in developing evidence-based policies and strategies. By examining the current health landscape and identifying areas for improvement, the research contributes to Saudi Arabia's overarching goal of providing high-quality healthcare services. This journey into exploring the healthcare needs, challenges, and opportunities reflects the nation's proactive approach to addressing the dynamic healthcare environment. The objectives set forth by this research align with the broader vision of enhancing the health and prosperity of all Saudi citizens.

Objectives: aim to provide a holistic assessment of the healthcare landscape in Al-Madina -Saudi Arabia, drawing from the valuable insights of academic study and contributing to developing evidence-based policies and strategies to enhance healthcare delivery and accessibility. By focusing on this critical aspect, we align with Saudi Arabia's vision to ensure the well-being and prosperity of all its citizens.

Methods: A cross-sectional study in Al-Madina, November 2023, using a self-administered questionnaire, with a sample size of 663, investigated healthcare-related aspects among the general population.

Conclusion: This research provided valuable insights into various aspects of health, encompassing epidemiological profiles, disease prevalence, healthcare infrastructure, and access to healthcare services. The study revealed notable demographic characteristics, including a high prevalence of obesity and a considerable percentage of individuals with chronic diseases, predominantly diabetes and hypertension. Despite a generally active population, the study highlighted a lack of interest and participation in pre-diagnosis examinations, emphasizing the need for increased awareness and education regarding the importance of regular check-ups.

Keywords: Body mass index - chronic diseases – walking – pre-diagnostic examination – healthcare facility – satisfaction.

description: We study dark matter for gaugino-mediated supersymmetry breaking and compact dimensions of order the grand unification scale. Higgs fields are bulk fields, and in general their masses differ from those of squarks and sleptons at the unification scale. As a consequence, at different points in parameter space, the gravitino, a neutralino or a scalar lepton can be the lightest (LSP) or next-to-lightest (NLSP) superparticle. We investigate the constraints from primordial nucleosynthesis on the different scenarios. While neutralino and gravitino dark matter with a sneutrino NLSP are consistent for a wide range of parameters, gravitino dark matter with a stau NLSP is strongly constrained.

description: The observation of duality by Mukherji and Mishra in one dimensional transport problems has been used to develop a general approach to classify and characterize the steady state phase diagrams. The phase diagrams are determined by the zeros of a set of coarse-grained functions without the need of detailed knowledge of microscopic dynamics. In the process, a new class of nonequilibrium multicritical points has been identified.

The long-term effects of the loss of a spouse or an adult child in later life
Creators: name: Nordan, Nancy
Publisher: name: University of British Columbia
Year: 2008

description: Of all the losses experienced in life, researchers have suggested that the two most disruptive and stressful are the death of a child and the death of a spouse. Drawing on the data from the national survey, American's Changing Lives: Wave 1, 1986, this study examines the long-term adjustment for older men and women two to fifteen years after the death of a spouse or an adult child. Bereaved spouses, bereaved parents and non-bereaved older adults were compared on multiple aspects of personal functioning by using Weiss's (1988) theoretical framework of effective functioning in everyday life (i.e., self-efficacy and perceived health), psychological comfort (i.e., depression), gratification (i.e., life satisfaction) and hopefulness for the future (i.e., fatalism, vulnerability and ability to plan). Two-factor (Bereavement X Gender) ANOVAs covarying age, race, income, education and number of children revealed fewer differences between the groups than expected; however, the bereaved adults were less likely to plan for the future and widowed adults reported higher self-efficacy and lower life satisfaction than non-bereaved adults. A main effect of gender for self-efficacy, depression, fatalism and vulnerability was found, with women reporting lower levels of personal functioning than men regardless of bereavement status. Also, these analyses demonstrated the importance of sociodemographic characteristics of age, race, education, and income on personal functioning in later life. A more exploratory analyses across the bereaved adults separately was conducted by using Three-factor (Bereavement X Gender X Time since Loss) ANOVAs covarying age, race, education and expectedness of loss. These results suggested that duration of bereavement may be a predictor of long-term personal adjustment. Widowed women bereaved for 6 to 15 years reported greater life satisfaction than those bereaved for 2 to 5 years, and bereaved adults of 6 to 15 years reported higher levels of completing plans and greater overall adjustment than those bereaved for 2 to 5 years. The discussion focuses on the overall patterns and the possible explanations for the similarities across the two losses, the pervasive role of gender and the strong and consistent influence of education on long-term adjustment in later life. The benefits of including both positive and negative indicators of personal functioning are also discussed. Future research should include appropriate comparisons groups, be longitudinal in nature and multidimensional in scope.

description: By large-scale quantum Monte Carlo simulations we show that grain boundaries in Helium-4 crystals are generically superfluid at low temperature, with a transition temperature of the order of ~0.5K at the melting pressure; insulating grain boundaries are found only for special orientations of the grains. We also find that close vicinity to the melting line is not a necessary condition for superfluid grain boundaries, and a grain boundary in direct contact with the superfluid liquid at the melting curve is found to be mechanically stable and the grain boundary superfluidity observed by Sasaki et al. [Science 313, 1098 (2006)] is not just a crack filled with superfluid.

Evidence for relativistic features in the X-ray spectrum of Mrk 335

description: We present an analysis of hard X-ray features in the spectrum of the bright Sy 1 galaxy Mrk 335 observed by the XMM-Newton satellite. Our analysis confi rms the presence of a broad, ionised iron Kalpha emission line in the spectrum, first found by Gondoin et al. The broad line can be modeled successfully by relativistic accretion disc reflection models. This interpretation is unusually robust in the case of Mrk 335 because of the lack of any ionised (`` warm'') absorber and the absence a clear narrow core to the line. Partial covering by neutral gas cannot, however, be ruled out statistically as the origin of the broad residuals. Regardless of the underlyin g continuum we report, for the first time in this source, the detection of a narrow absorption feature at the rest frame energy of ~5.9 keV. If the feature is identified with a resonance absorption line of iron in a highly ionised medium, the redshift of the line corresponds to an inflow velocity of ~0.11 -0.15 c. We present a simple model for the inflow, accounting approximate ly for relativistic and radiation pressure effects, and use Monte Carlo methods to compute synthetic spectra for qualitative comparison with the data. This mode ling shows that the absorption feature can plausibly be reproduced by infalling gas providing that the feature is identified with Fe xxvi. We require the inflowing gas to extend over a limited range of radii at a few tens of rg to match the observed feature. The mass accretion rate in the flow correspond s to 60% of the Eddington limit, in remarkable agreement with the observed rate . The narrowness of the absorption line tends to argue against a purely gravitational origin for the redshift of the line, but given the current data quality we stress that such an interpretation cannot be ruled out.

description: We review recent developments in the Casimir effect which arises in quantization volumes restricted by material boundaries and in spaces with non-Euclidean topology. The starting point of our discussion is the novel exact solution for the electromagnetic Casimir force in the configuration of a cylinder above a plate. The related work for the scalar Casimir effect in sphere-plate configuration is also considered, and the application region of the proximity force theorem is discussed. Next we consider new experiments on the measurement of the Casimir force between metals and between metal and semiconductor. The complicated problem connected with the theory of the thermal Casimir force between real metals is analyzed in detail. The present situation regarding different theoretical approaches to the resolution of this problem is summarized. We conclude with new constraints on non-Newtonian gravity obtained using the results of latest Casimir force measurements and compare them with constraints following from the most recent gravitational experiments.

description: We present results of the first survey of high-redshift ( ~ 2.3) OVI absorption systems along parallel lines of sight toward two lensed QSOs. After a careful and well-defined search, we find ten intervening OVI systems. Within the errors, all OVI systems appear at the same redshift and have similar line strengths in front of both QSO images, whereas in most cases CIV or SiIV show more differences across the lines of sight, either in radial velocity or line strength. We conclude that (1) the coherence length of OVI must be much larger than ~ 1 kpc, and (2) an important fraction of the CIV absorbers may not reside in the same volume as OVI. Since Doppler parameters are consistent with photoionization, we propose a model in which CIV occurs in two different photoionized phases, one large, with characteristic sizes of a few hundred kpc and bearing OVI, and another one a factor of ten smaller and containing CIII. This model is able to explain the various transverse differences observed in column density and kinematics. We apply the model successfully to 2 kinds of absorbers, with low and high metallicity. In the low-metallicity regime, [C/H] \~ -2, we find that [C/O] ~ -0.7 is required to explain the observations, which hints at late (z < 6) rather than early metal enrichment. In the high-metallicity regime, the observed dissociation between OVI and CIV gas might be produced by galactic outflows. Altogether, the relative abundances, inhomogeneous CIV and featureless OVI are consistent with gas that has been processed recently before the absorption occurred (thus close to star-forming regions). Finally, we discuss briefly three associated systems (z_abs ~ z_em) that also show OVI. (abridged)

description: The in-orbit performance and calibration of the Hard X-ray Detector (HXD) on board the X-ray astronomy satellite Suzaku are described. Its basic performances, including a wide energy bandpass of 10-600 keV, energy resolutions of ~4 keV (FWHM) at 40 keV and ~11% at 511 keV, and a high background rejection efficiency, have been confirmed by extensive in-orbit calibrations. The long-term gains of PIN-Si diodes have been stable within 1% for half a year, and those of scintillators have decreased by 5-20%. The residual non-X-ray background of the HXD is the lowest among past non-imaging hard X-ray instruments in energy ranges of 15-70 and 150-500 keV. We provide accurate calibrations of energy responses, angular responses, timing accuracy of the HXD, and relative normalizations to the X-ray CCD cameras using multiple observations of the Crab Nebula.

A comparative analysis of police corruption in the US and Turkey
Creators: name: Sarikaya, Yusuf
Publisher: name: No Publisher Supplied
Year: 2015

description: Although police represent the law and justice system, police corruption cases still occur in many police organizations around the world. This cross national study examined and compared the perceptions of Turkish and American police officers regarding police corruption. The data that was collected by the researcher from TNP was used as a primary data; on the other hand, the dataset of Klockars et al’s study was used as a secondary data.   This research examined the police corruption problem on the basis of organizational level explanations considering individual and societal approaches rather than the traditional limited view. In this study, a cross-sectional survey research design including a survey questionnaire, along with hypothetical scenarios based primarily on temptations faced by officers in their daily work was applied.   The findings of this study demonstrated significant agreements between the Turkish and American police officers’ perceptions especially on the most serious cases. This agreement showed a consensus between the American and Turkish police officers perception about what they considered as being serious. While the Turkish and American police officers come from different economic, social, political, cultural environments, they share a common understanding of corruption seriousness.  According to the findings, both the Turkish and American respondents are not willing to report all the misbehaviors of their colleagues even they perceive those behaviors as being unethical. The results showed that ‘the code of silence’ and ‘loyalty’ to colleagues exist in the TNP and American police agencies.   This research also investigated factors contributing to officers’ perception of seriousness. “Income satisfaction level” and “supervisory position” have significant effects on Turkish police officers’ attitude toward corruption. “Supervisory position”, “length of service” and “current assignment unit” have significant effects on American police officers.   This study did not aim to measure the extent of police corruption in any police agency of Turkey or the US, but tried to shed light on some scientifically unexplored aspects of the police corruption phenomena in the US and Turkey.

description: Measured ratios of decay rates for Ke3/K2π, K\mu3/K2πand K\mu3/Ke3 are presented. These measurements are based on K^+- decays collected in a dedicated run in 2003 by the NA48/2 experiment at CERN. The results obtained are Ke3/K2π= 0.2470 +/- 0.0009 (stat) +/- 0.0004 (syst) and K\mu3/K2π= 0.1637 +/- 0.0006 (stat) +/- 0.0003 (syst). Using the PDG average for the K^+- -> π^+-π^0 normalisation mode, both values are found to be larger than the current values given by the Particle Data Book and lead to a larger magnitude of the |V_{us}| CKM element than previously accepted. When combined with the latest Particle Data Book value of |V_{ud}|, the result is in agreement with unitarity of the CKM matrix. In addition, a new measured value of K\mu3/Ke3 = 0.663 +/- 0.003(stat) +/- 0.001(syst) is compared to the semi-empirical predictions based on the latest form factor measurements.

Sediment in forested and logged gullies, coastal British Columbia
Creators: name: Millard, Thomas H.
Publisher: name: University of British Columbia
Year: 2008

description: This study examines sediment storage and transfers in gullies of coastal British Columbia, and how logging affects sediment storage and transfers. Both fluvial and debris flow transport of sediment occur in gullies, and the amount of fluvial transport of sediment which occurs will affect the magnitude of a subsequent debris flow. Coarse woody debris (CWD) may affect the storage and transfer of sediment in the gully channel, and logging can affect the supply and type of CWD. To determine whether logging affects storage and transfer of sediment in gullies, sediment budgets were constructed for gullies in four treatment classes: A. Logged, slash full, no recent debris flows : "slash-full (SF)." B. Logged, slash removed, no recent debris flows : "slash-clear (SC)." C. Logged, naturally scoured by debris flows : "torrented (T)." D. Unlogged, naturally loaded with CWD : "unlogged (U)." Each sediment budget had input to the channel, storage in the channel, and output from the channel estimated. Significant differences between treatment types occurred, summarized below. Treatment classes grouped together (in brackets) did not have significant differences. Budget term : Input, greatest→least, Torrented→Slash-full→(Unlogged and Slash-clear). Budget term : Storage, greatest→least, Torrented→Unlogged→Slash-clear. Budget term : Output, greatest→least, Slash-clear→(Torrented and Unlogged)→Slash-full. One objective of the study was to assess the effectiveness and feasibility of cleaning slash from the gully channels. To be effective, cleaning slash must either reduce the magnitude of a debris flow in a treated gully, or else reduce the likelihood of initiation of a debris flow in the treated gully. Removal of slash will reduce the volume of a subsequent debris flow by about 15 percent, simply from the reduction in the amount of CWD. Reduction in sediment stored in the treated channel may reduce the volume of a debris flow by a further 4 percent. There is no evidence that removing slash will decrease the likelihood of initiation of a debris flow.

description: We develop a formalism to study non-local higher-dimensional effects in braneworld scenarios from a four-dimensional effective theory point of view and check it against the well-known Garriga-Tanaka result in the appropriate limit. We then use this formalism to study the spectrum of density perturbations during inflation as seen from the lower-dimensional effective theory. In particular, we find that the gravitational potential is greatly enhanced at short wavelengths. The consequences to the curvature perturbations are nonetheless very weak and will lead to no characteristic signatures on the power spectrum.

It is an expression of the social character of the Church. Not only this, but also embodies the teaching, the belief and the dogma of the Church, transforming them into a way of life. This master thesis aims to shed light on the pastoral care which offers or wished to be offered by the Spiritual Centers which are perceived as organization and operation of the pastoral care. The study tries to present theological elements that inspire the pastoral work and suggests structures and ways for practicing and activating the pastoral care in the life of the Church through the Spiritual Centers.
Land use analysis for agroforestry research and development: a case study for Luwero district in Uganda
Creators: name: Muwanga, Joyce N.
Publisher: name: University of British Columbia

description: A land use evaluation in Luwero district of Uganda was undertaken as the primary stage in planning for appropriate agroforestry research and development. Published information sources, personal interviews, discussions with key informants and a survey of 50 randomly selected households across the banana-coffee farming system were used in the study. The biophysical environment at altitudes of 1000-1300 m a.s.l is characterised by undulating topography intersected with river valleys. The climate is characterised by a mean temperature range of 15°C (minimum) to 30°C (maximum) with pronounced wet and dry seasons; the bimodally distributed annual rainfall is 1000-2000 mm. Soils are predominantly ferralsols (Oxisols) supporting a forest-savanna mosaic vegetation type. The socio-economic environment is characterised by an aging population (>50 years), widespread temporary landownership, and a predominance of family labour. Shortages of cash, lack of credit facilities and external inputs, poor marketing and transportation infrastructure, and inadequate extension services are identified constraints. The banana-coffee production system is organized on a subsistance level with crop production carried out ungentle slopes, in home gardens and in plots on the outer edges of the homegardens; cooking bananas are the main staple. Cash crops (cotton and coffee) are neglected. Soil fertility management is inadequate. Livestock production is a minor component of the system; various livestock are kept for home consumption and cash income. Trees occupy traditional niches in home gardens and compounds for provision of shade and fruits. Secondary roles include fuel wood, building materials, raw materials, fencing and windbreaks. Ficus natalensis, Albizia spp., Markhamia lutea and a range of fruit trees are grown. Production is constrained by socio-economic problems which are exacerbated by declining soil fertility, lack of external inputs, poor farm management, and low quality fodder. Improved production would require attention to: (i) cash availability, (ii) cash, food crops and livestock production, (iii) tree cultivation and (iv) land tenure. These areas may be addressed by: (i) re-settlement assistance to farmers, (ii) provision of credit facilities and secure land tenure, (iii) improvement in service infrastructure and extension services, (iv) agroforestry education, and (v) intensified soil fertility management. Agroforestry practices to address production constraints should involve implementation of strategies which are readily adoptable and include: (i) use of upperstorey trees in home gardens and/or coffee plots, (ii) expansion of fruit tree cultivation, (iii) development of fodder banks, and (iv) boundary tree planting. Additional agroforestry practices, such as alley cropping, will require further research and education via institutional demonstration trials.

description: In this paper we present a grid of stellar evolution models, computed with an up-to-date physical description of the internal structure, using the Code d'Evolution Stellaire Adaptatif et Modulaire (CESAM). The evolutionary sequences span from the pre-main sequence to the beginning of the Red Giant Branch and cover an interval of mass typical for low and intermediate mass stars. The chemical composition (both helium and metal abundance) is the solar one. The frequencies of oscillation, computed for specific stellar models of the grid using the Porto Oscillations Code (POSC), are also provided. This work was accomplished in order to support the preparation of the CoRoT mission within the Evolution and Seismic Tools Activity (CoRoT/ESTA). On the other hand, the grid can also be used, more generally, to interpret the observational properties of either individual stars or stellar populations. The grids (data and documentation) can be found at http://www.astro.up.pt/corot/models/cesam

description: We have identified a metal-strong (logN(Zn+) > 13.15 or logN(Si+) > 15.95) DLA (MSDLA) population from an automated quasar (QSO) absorber search in the Sloan Digital Sky Survey Data Release 3 (SDSS-DR3) quasar sample, and find that MSDLAs comprise ~5% of the entire DLA population with z_abs > 2.2 found in QSO sightlines with r < 19.5. We have also acquired 27 Keck ESI follow-up spectra of metal-strong candidates to evaluate our automated technique and examine the MSDLA candidates at higher resolution. We demonstrate that the rest equivalent widths of strong ZnII 2026 and SiII 1808 lines in low-resolution SDSS spectra are accurate metal-strong indicators for higher-resolution spectra, and predict the observed equivalent widths and signal-to-noise ratios needed to detect certain extremely weak lines with high-resolution instruments. We investigate how the MSDLAs may affect previous studies concerning a dust-obscuration bias and the N(HI)-weighted cosmic mean metallicity . Finally, we include a brief discussion of abundance ratios in our ESI sample and find that underlying mostly Type II supernovae enrichment are differential depletion effects due to dust (and in a few cases quite strong); we present here a handful of new Ti and Mn measurements, both of which are useful probes of depletion in DLAs. Future papers will present detailed examinations of particularly metal-strong DLAs from high-resolution KeckI/HIRES and VLT/UVES spectra.

Robustness against parametric noise of non ideal holonomic gates

description: Holonomic gates for quantum computation are commonly considered to be robust against certain kinds of parametric noise, the very motivation of this robustness being the geometric character of the transformation achieved in the adiabatic limit. On the other hand, the effects of decoherence are expected to become more and more relevant when the adiabatic limit is approached. Starting from the system described by Florio et al. [Phys. Rev. A 73, 022327 (2006)], here we discuss the behavior of non ideal holonomic gates at finite operational time, i.e., far before the adiabatic limit is reached. We have considered several models of parametric noise and studied the robustness of finite time gates. The obtained results suggest that the finite time gates present some effects of cancellation of the perturbations introduced by the noise which mimic the geometrical cancellation effect of standard holonomic gates. Nevertheless, a careful analysis of the results leads to the conclusion that these effects are related to a dynamical instead of geometrical feature.

description: Hans Bethe contributed in many ways to our understanding of the supernovae that happen in massive stars, but, to this day, a first principles model of how the explosion is energized is lacking. Nevertheless, a quantitative theory of nucleosynthesis is possible. We present a survey of the nucleosynthesis that occurs in 32 stars of solar metallicity in the mass range 12 to 120 solar masses. The most recent set of solar abundances, opacities, mass loss rates, and current estimates of nuclear reaction rates are employed. Restrictions on the mass cut and explosion energy of the supernovae based upon nucleosynthesis, measured neutron star masses, and light curves are discussed and applied. The nucleosynthetic results, when integrated over a Salpeter initial mass function (IMF), agree quite well with what is seen in the sun. We discuss in some detail the production of the long lived radioactivities, 26Al and 60Fe, and why recent model-based estimates of the ratio 60Fe/26Al are overly large compared with what satellites have observed. A major source of the discrepancy is the uncertain nuclear cross sections for the creation and destruction of these unstable isotopes.

Coherence and Intermittency of Electron Density in Small-Scale Interstellar Turbulence

description: Spatial intermittency in decaying kinetic Alfven wave turbulence is investigated to determine if it produces non Gaussian density fluctuations in the interstellar medium. Non Gaussian density fluctuations have been inferred from pulsar scintillation scaling. Kinetic Alfven wave turbulence characterizes density evolution in magnetic turbulence at scales near the ion gyroradius. It is shown that intense localized current filaments in the tail of an initial Gaussian probability distribution function possess a sheared magnetic field that strongly refracts the random kinetic Alfven waves responsible for turbulent decorrelation. The refraction localizes turbulence to the filament periphery, hence it avoids mixing by the turbulence. As the turbulence decays these long-lived filaments create a non Gaussian tail. A condition related to the shear of the filament field determines which fluctuations become coherent and which decay as random fluctuations. The refraction also creates coherent structures in electron density. These structures are not localized. Their spatial envelope maps into a probability distribution that decays as density to the power -3. The spatial envelope of density yields a Levy distribution in the density gradient.

A selection of applications at Canada Customs
Creators: name: Munro, Laura
Publisher: name: University of British Columbia
Year: 2008

description: Canada Customs is currently faced with problems of overcrowding. This situation causes lost revenue and potential control problems, and detracts from its public image. Customs administration is interested in determining what changes, if any, can be made to help alleviate the problem. The goal of this paper is to analyze several alternatives which are available to customs officials, and to recommend changes which can be implemented to improve the current situation. To achieve this goal, several applications of Management Science methods were performed. The first application involved a cost-benefit analysis of the Peace Arch Crossing Entry (PACE) Project. It was found that the PACE project has positive net benefits of approximately $9.5 million provided that it is supported by sufficient staff levels. Results of the cost-benefit analysis also indicate that the social benefits of having an extra staff member available far outweigh the costs involved. In the second application performed, multiple regression techniques were used to analyze various characteristics of travellers which affect service time within the customs office. As a result, it is recommended that customs officials look into the possibility of keeping certain groups of individuals (whose processing times are relatively low) separate from the main flow of travellers, in order to save these travellers a great deal of time. In the third application, simulation and animation were used to replicate the current situation in the Pacific Highway Customs Office. Experiments were then conducted to determine the optimal mix of regular terminals and Self Declaration System (SDS) terminals. It was found that implementing SDS was not as efficient as adding a new regular terminal. It is recommended that a study be conducted to determine by how much the times for SDS can be reduced. If significant reductions in time are not possible, it may be in the best interest of all concerned to revert the SDS terminals to regular terminals.

description: In this note we establish a (non-trivial) lower bound on the degree two entry $h_2$ of a Gorenstein $h$-vector of any given socle degree $e$ and any codimension $r$. In particular, when $e=4$, that is for Gorenstein $h$-vectors of the form $h=(1,r,h_2,r,1)$, our lower bound allows us to prove a conjecture of Stanley on the order of magnitude of the minimum value, say $f(r)$, that $h_2$ may assume. In fact, we show that $$\lim_{r\to \infty} {f(r)\over r^{2/3}}= 6^{2/3}.$$ In general, we wonder whether our lower bound is sharp for all integers $e\geq 4$ and $r\geq 2$.

The institutional factors that influence women's agricultural productivity : the case of Igbo women of South-Eastern Nigeria
Creators: name: Nnazor, Agatha Ifeyinwa
Publisher: name: University of British Columbia
Year: 2008

description: This thesis examines the role of women in agricultural development and identifies the institutional factors (access to land; credit; machines, improved seedlings and fertilizer; extension services; cooperative facilities) that constitute a hindrance to their agricultural productivity. From an interview survey conducted with fifty Igbo women from two rural Igbo communities - Umunnachi and Leru, the researcher derives data on the roles of Igbo women and the institutional factors that influence their agricultural productivity. The data reveal that Igbo women play extensive roles both as reproducers of human agents (bearers and rearers of children, care of the aged, the handicap and maintainers of labour force) and producers of food. In spite of the numerous roles of Igbo women, they have limited access to agricultural facilities. In line with the socialist feminist view, the thesis locates women's limited access to agricultural facilities in the patriarchal and class structures of the society which not only favour men as a gender but also as a class. The thesis argues that women's limited access to agricultural facilities partly explains their low agricultural productivity and the current food shortages facing the country, Nigeria.
