description: The present study was conducted to compare leaf extracts of Y. gloriosa, Y. treculeana, Y. filamentosa and Y. aloifolia. Plant extracts were obtained by sequential extraction with 50% and 100% methanol using the pressurized liquid extraction method. General comparative analysis of Yucca extracts was performed by 2 D-NMR. The presence of various biologically active components in the extracts was shown, among which steroid saponins predominate. The use of LC-MS and LC-HRMS methods with electrospray ionization made it possible to conduct a comparative analysis of Yucca steroidal saponins. The 33 steroidal saponins of various structures were found. The presence of three characteristic saponins in all Yucca species was shown: yuccaloeside C, yuccaloeside E and yuccaloeside B. The results obtained can be used to control the quality of plant materials and products.

description: The paper presents a group of articles, published in the same issue of Moneta e Credito or accepted for publication in subsequent issues, dealing with different aspects of the "new economics of knowledge and information" and with "Internet economics". It also surveys the economic aspects of the new information and communication technologies, considering them as a Schumpeterian "epoch-making innovation" (and suggesting that Internet could be considered as a new, separate, epoch-making innovation). Attention is drawn to the issue of market forms likely to prevail in the field ofInternet services, on the inapplicability of the traditional theory of competitive equilibrium, and on the dynamic kind of competition based on technological change prevailing in the sector, likely to foster some sort of unstable oligopolistic behaviour.

description: An experiment was conducted in controlled environment chambers to evaluate the effect of varying levels of blue light on vine growth and storage root yield of sweetpotato [ I p o m o e a batatas (L.) Lam.] when grown in nutrient film technique (NFT). Cuttings of'TU-82-155" sweetpotato were grown under 6, 11, 16, 22.5, and 26% blue light (320-496 nm) supplied by high intensity discharge metal halide and high pressure sodium lamps. Total fresh mass was greatest for plants grown under 22.5 or 26% , and lowest for plants under 11% blue light. Total plant dry mass and storage root yield, however, were similar among treatments. Harvest index (storage root dry mass/total plant dry mass) was highest for plants grown under 26% blue light. Plants grown under 26% blue light tended to have a higher growth rate. Both vine and internode length tended to decline as the percentage of blue photons increased. These results indicate that storage root yield was not adversely affected by exposure to blue light as high as 26%, and that the main effect of blue light was to cause a reduction in vine length.

description: This paper focuses on the role of knowledge within the process of growth and job creation in the European Union. Many features of the so-called knowledge-based economy are connected with the increasing use of information and communication technologies (ICT), that radically changes the conditions for the production and distribution of knowledge as well as its coupling to the production system. Technological change not only stimulates investment in physical capital but also brings to knowledge accumulation: human skills are required to implement, maintain, adapt and use technologies embodied in physical capital. Indeed, as new technologies become more widespread, certain skills may be less in demand--because many tasks once carried out manually are now performed by automated equipment--while the demand for workers able to maintain, program, and develop these sophisticated technologies rise. There is therefore concern that technological change may cause unemployment as the result of a mismatch between the demand for labour and the various skills of workers; in this way it may also increase the polarisation of society by widening the gap in income and employment opportunities between those whose skills have been displaced by new technology and those who create and use it.

description: We propose a Monte-Carlo-based method for reconstructing sparse signals in the formulation of sparse linear regression in a high-dimensional setting. The basic idea of this algorithm is to explicitly select variables or covariates to represent a given data vector or responses and accept randomly generated updates of that selection if and only if the energy or cost function decreases. This algorithm is called the greedy Monte-Carlo (GMC) search algorithm. Its performance is examined via numerical experiments, which suggests that in the noiseless case, GMC can achieve perfect reconstruction in undersampling situations of a reasonable level: it can outperform the $\ell_1$ relaxation but does not reach the algorithmic limit of MC-based methods theoretically clarified by an earlier analysis. The necessary computational time is also examined and compared with that of an algorithm using simulated annealing. Additionally, experiments on the noisy case are conducted on synthetic datasets and on a real-world dataset, supporting the practicality of GMC.

description: A geographic information system was used to demonstrate a methodology for assignment of best management practices that integrate land capability and crop suitability zoning on an agricultural watershed on St. Lucia. Primary parameters used in determining land capability included slope steepness and soil stability. Land capability classes were delineated, and recommended agricultural, agro-forestry and forestry prescriptions were assigned across the watershed. Crop suitability over the watershed was analyzed for selected tree crops, using fiizzy-set membership to represent variability in slope, rainfall and soil parameters in crop growth. The procedures developed in this study will contribute to a spatially-based decision support system toward conservationoriented agricultural and forestry land planning on St. Lucia. The study demonstrates the effectiveness of GIS in the application of spatial modelling procedures in rapidly evaluating watershed management strategies.

description: Al igual que la mayoria de los paises Latinoamericanos y del Caribe desde mediados de la década de los 80s, en la Republica Dominicana se han llevado a cabo esfuerzos para reestructurar, fortalecer y reorganizar su sistema national de investigation agricola. El proceso se initio en 1984 con una evaluation del sistema national de investigation agricola que realizô el ISNAR. El informe final recomendô la creation del Instituto Dominicano de Investigaciones Agropecuarias (IDIA) como un ente con independencia politica y financiera fuera del sector pùblico. Por distintas razones el IDIA nunca ha sido puesto en funcionamiento. En respuesta a las necesidades del sector agropecuario, en 1987, se creô una organization privada, sin fines de hicro, llamada Fundaciôn de Desarrollo Agropecuario (FDA) actualmente denominada Centro para el Desarrollo Agropecuario y Forestal (CEDAF). El objetivo de la organization fue y es aùn apoyar al sector agropecuario y de recursos naturales en la Republica Dominicana a través del financiamiento de actividades de investigation, capacitaciôn, asistencia técnica y difusiôn de information. El CEDAF esta considerado a nivel national e international como uno de las mâs exitosos mecanismos de financiamiento y promotion de proyectos de investigation agricola y capacitaciôn. Los elementos principales para ese éxito son: 1) Una marcada orientation a la solution de problemas de los agricuhores; 2) Sostenibilidad financiera; 3) Capacidad de respuesta a las demandas de los usuarios; 4) Liderazgo y; 5) Personal altamente comprometido con la institution. Basado en sus mâs de 10 anos de experiencia, trabajando con productores y agroempresarios, el CEDAF es miembro de distintas organizaciones internacionales continentales y regionales de investigation agricola.

description: α-Glucosidase inhibitory assay-guided purification of Thunbergia laurifolia L. stems yielded a new compound named 5-acetoxyfuranonapthoquinone (1) along with nineteen known compounds (2-20). The structures of the isolated compounds were elucidated by the analysis of multiple spectroscopic data. The isolated compounds were evaluated for α-glucosidase inhibition. Syringaresinol (7), rosmarinic acid (11), 1,2,8-trihydroxyxanthone (16), and isojacareubin (18) showed the most potent inhibitory activity among isolated compounds. Kinetic study indicated that syringaresinol (7), 1,2,8-trihydroxyxanthone (16) and isojacareubin (18) could inhibit maltase and sucrase function by non-competitive manner, and rosmarinic acid (11) was identified as a non-competitive inhibitor against maltase and a mixed-manner inhibitor against sucrase.

description: A new alkaloid, 2-acetyl-4-methoxyfuro[2,3-b]quinoline (1), and a new benzaldehyde derivative, (2′S)-4-(2′-hydroxy-3′-methyl-3′-butenoxy)benzaldehyde (2), were isolated from the twig of Zanthoxylum rhetsa (Roxb.) DC. along with twenty-six known compounds (3−28). Their structures were determined by spectroscopic analysis (1D and 2D NMR spectroscopy and HRMS analysis) and comparison with data reported in the literature. Thirteen of the known compounds were evaluated for their cytotoxic activities against human cancer cell lines that included MDA-MB-231, SW1353, A549, and HCT116. (±)-8-Acetonyldihydronitidine (15) showed moderate cytotoxicity toward the SW1353 cancer cell line with an IC50 value of 18.90±0.39 µg/mL, and exhibited weak cytotoxic activity against MDA-MB-231, A549 and HCT116 cell lines with IC50 values of 49.86−71.32 µg/mL.

description: With the direct detection of gravitational waves by advanced LIGO detector, a new "window" to quantum gravity phenomenology has been opened. At present, these detectors achieve the sensitivity to detect the length variation ($δL$), $\mathcal{O} \approx 10^{-17}-10^{-21}$ meter. Recently a more stringent upperbound on the dimensionless parameter $β_0$, bearing the effect of generalized uncertainty principle has been given which corresponds to the intermediate length scale $l_{im}= \sqrt{β_0} l_{pl} \sim 10^{-23} m$. Hence the flavour of the generalized uncertainty principle can be realised by observing the response of the vibrations of phonon modes in such resonant detectors in the near future. In this paper, therefore, we calculate the resonant frequencies and transition rates induced by the incoming gravitational waves on these detectors in the generalized uncertainty principle framework. It is observed that the effects of the generalized uncertainty principle bears its signature in both the time independent and dependent part of the gravitational wave-harmonic oscillator Hamiltonian. We also make an upper bound estimate of the GUP parameter.

description: The beekeeping industry in the Western Hemisphere has faced several major challenges in recent years, namely, bee mites, Africanized bees, and chemical pesticides. The newest threat is the small hive beetle, Aethina tumida, Murray, which was first reported in die USA in St. Lucie County, Florida, in June of 1998. It is a member of the beetle family, Nitidulidae, commonly known as "sap beetles." Within less than a year, it had been reported in four southern states, namely, Florida, Georgia, South Carolina, and North Carolina, and recently six more states have been added to die list. Its origin is believed to be in South Africa where it is considered a secondary pest. In the USA, however, the insect appears to be developing into a potential significant pest. The adults and larvae feed on honey and pollen in the beehive. The larvae burrow through the combs and defecate in them causing die honey to ferment and even leak out of the combs. The odor is reportedly similar to that of decaying oranges. Research is needed to explore effective control measures. One important consideration is that the larvae leave the beehive to pupate in the soil.

description: There are indications that interstellar and interplanetary dust grains have an inhomogeneous and fluffy structure. We investigate different methods to describe light scattering by such composite particles. Both a model of layered particles and discrete dipole calculations for particles with Rayleigh and non-Rayleigh inclusions are used. The calculations demonstrate that porosity is a key parameter for determining light scattering. We find that the optical properties of the layered particles depend on the number and position of layers if the number of layers is small ($\la 15$). For a larger number of layers the scattering characteristics become independent of the layer sequence. The optical properties of particles with inclusions depend on the size of inclusions provided the porosity is large. The scattering characteristics of very porous particles with inclusions of different sizes are found to be close to those of multi-layered spheres. We compare the results of these calculations with the predictions of the effective medium theories (EMT) which are often used in astronomy as a tool to calculate the optical properties of composite particles. The results of our analysis show that the internal structure of grains (layers versus inclusions) only slightly affects the optics of particles provided the porosity does not exceed 50%. It is also demonstrated that in this case the optical properties of composite grains calculated with EMT agree with the results of the exact method for layered particles. For larger porosity, the standard EMT rules (i.e., Garnett and Bruggeman rules) give reliable results for particles with Rayleigh inclusions only.

We include the latest 766.3 ton year KamLAND data in our analysis. We also present the allowed values of parameters $Δm^2_{atm}$ and $\sin^2θ_{atm}$ from two generation oscillation analysis of SuperKamiokande atmospheric and K2K data. For both cases we discuss the precision achieved in the present set of experiments and also how the precision can be improved in future. We also obtain the bounds on $θ_{13}$ from three generation analysis of global oscillation data. We emphasise on the roles played by different data sets in constraining the allowed parameter ranges.

description: Use of herbicides and hand weeding are common practices for weed control in root and tuber crops throughout the Caribbean Basin. In Puerto Rico, herbicides ametryn and paraquat are registered for use in some root and tuber production, but no herbicides are registered for arracacha. Knowing the time at which weeds begin to interfere with arracacha will permit optimum timing for weed control practices. The objective of this study was to determine the effects of various duration periods of weed interference on arracacha plant dry weight, stand and fresh corm yield. The study was established using periods of interference as treatments. Weeds were allowed to grow for 0, 1, 3, 5, 7, 11, and 40 weeks after transplanting. Plant dry weight was reduced linearly at a rate of 32 g/m2 for each week of interference. Plants per hectare were reduced at a rate of 185 plants/ha for each week of interference. Analysis indicated a quadratic relationship between corm yield and lengths of weed interference.

The results, which are confirmed by separate estimations for individual industries or groups thereof, support the hypothesis that the ICTs are a general-purpose technology, or a new technological paradigm. This is because, like with electricity, they influence the productivity of firms in many industries, including traditional ones. Moreover, the firms with higher investments in ICTs show higher employment growth. Our results also indicate that there are differences among firms in the propensity to invest in the ICTs, irrespective of their industry.

description: In recent years, the Caribbean has been facing several new and resurgent pest problems brought on by rapid means of transport and increased intra and extra regional trade. These have been a threat to both agricultural production and die environment. For most alien pests, classical biological control is often the solution. The application of biological control has been evolving to address new concerns, particularly those regarding the safety of introduced natural enemies. The recent successful introduction of exotic natural enemies against the hibiscus or pink mealybug, Maconellicoccus hirsutus, has heightened public awareness of biological control and opened up opportunities for developing integrated pest management (IPM) programmes. This paper examines two separate but related issues: safety of biological control and prospects for IPM in the Caribbean.

description: This is the report of neutrino and astroparticle physics working group at WHEPP-8. We present the discussions carried out during the workshop on selected topics in the above fields and also indicate progress made subsequently. The neutrino physics subgroup studied the possibilites of constraining neutrino masses, mixing and CPT violation in lepton sector from future experiments. Neutrino mass models in the context of abelian horizontal symmetries, warped extra dimensions and in presence of triplet Higgs were studied. Effect of threshold corrections on radiative magnification of mixing angles was investigated. The astroparticle physics subgroup focused on how various particle physics inputs affect the CMBR fluctuation spectrum, and on brane cosmology. This report also contains an introduction on how to use the publicly available code CMBFAST to calculate the CMBR fluctuations.

We derive second-law-like inequalities for the average work done in the presence of gambling, and universal stopping-time fluctuation relations for classical and quantum non-stationary stochastic processes. We test experimentally our results in a single-electron box, where an electrostatic potential drives the dynamics of individual electrons tunneling into a metallic island. We also discuss the role of coherence in gambling demons measuring quantum jump trajectories.

description: The phytochemical investigation of the stem bark crude extract of Aniba firmula (Lauraceae) led to the isolation of undescribed bicyclic [3.2.1] octane neolignans, 1 and 2, characterized by unusual bicyclic patterns and two other known bicyclic neolignans 3 and 4. Anti-inflammatory bicyclic [3.2.1] octane neolignans metabolites were previously reported in the literature, and the A. firmula stands out in the Lauraceae family as a source of potentially bioactive compounds. Thus, herein the anti-inflammatory potential of four isolated compounds from A. firmula was accessed via an ex vivo anti-inflammatory model that included plasmatic quantification of the prostaglandin E2 (PGE2) inflammatory mediator. Compounds 2 and 3 exhibited significant anti-inflammatory activity by inhibiting the production of PGE2 in plasma samples, thus by interference with the cyclooxygenase (COX) inflammatory pathway. Therefore, these findings demonstrate that the bicyclic octane neolignan classes [3.2.1] can present anti-inflammatory potential.

description: There is growing emphasis in the policy debate on rural women’s entrepreneurship as a poverty alleviation strategy and a preferred tactic to spur economic development. To this end, this synthesis report puts into perspective the nature of Uganda’s rural woman entrepreneurs, paying close attention to the women targeted by the Uganda Women Entrepreneurship Programme (UWEP). This report focuses on rural women’s entrepreneurship. However, challenges identified may not be limited to this category alone but also extend to the poorest urban entrepreneurs with similar characteristics. Using qualitative and quantitative data from the Uganda Bureau of Statistics (UBoS), findings indicate that: Most rural women are illiterate (about 75 percent) and run informal non-farm enterprises that are micro and seasonal in nature. Accessing finance through local groups such as Rotating Savings and Credit Associations was most common for rural women in business. Thus, training materials particularly the financial component, mentoring and an early warning system for these entrepreneurs should be established together with effective management and leadership of these groups. For growth to occur, it is important for groups to take bigger loans as an indication of business expansion and growth. The government needs to resume adult literacy programmes within the UWEP.

description: We present a mean field approach based on pairs of fermionic atoms to describe condensates in the BEC-BCS crossover regime. By introducing an effective potential, the mean field equation allows us to calculate the chemical potential, the equation of states and the atomic correlation function. The results agree surprisingly well with recent quantum Monte Carlo calculations. We show that the smooth crossover from the bosonic mean field repulsion between molecules to the Fermi pressure among atoms is associated with the evolution of the atomic correlation function.
Internet pricing: una breve rassegna critica (Internet Pricing: A Short Critical Survey)

Subjects: subject: Pricing
subject: L86, L11

description: In the article, some recent literature on Internet pricing is surveyed. The author looks at the topic by setting it in the more general framework of the analysis of activities that can be regarded as similar to Internet from the technological and economic point of view. In particular, attention is focused on the problem of the divergence between private and social costs when there occurs network congestion and the problem of efficient prices in activities characterized by the existence of peak-loads. The author argues that dealing with such issues in the context of Internet cannot be reduced to a straightforward application of traditional results of welfare economics and the literature on peak-load pricing. In a competitive market with similar features to the market for Internet services, it is well possible that there do not exist incentives that induce firms to adopt price systems such as to prevent and/or eliminate congestion. Further theoretical and analytical developments are then in order. JEL Codes: L86, L11 Keywords: Pricing

description: Two new resin glycosides, muricatins XII (1) and XIII (2), were isolated from the crude resin glycoside fraction of the seeds of Ipomoea muricata (L.) Jacq. (Convolvulaceae), along with three known ones, muricatins V (3), VI (4), and IX (5). Compounds 1 and 2 contained new glycosidic acids, muricatic acids E (1a) and F (2a), respectively. The structures of these compounds were determined using data obtained from spectroscopy measurements and chemical evidence. The results suggested that 1 and 2 have macrolactone structures (jalapins). Furthermore, the cytotoxic activity of the crude resin glycoside fraction and 3–5 against HL-60 human promyelocytic leukaemia cells was evaluated. All tested samples demonstrated cytotoxic activities.
A local representation formula for quaternionic slice regular functions

description: After their introduction in 2006, quaternionic slice regular functions have mostly been studied over domains that are symmetric with respect to the real axis. This choice was motivated by some foundational results published in 2009, such as the Representation Formula for axially symmetric domains. The present work studies slice regular functions over domains that are not axially symmetric, partly correcting the hypotheses of some previously published results. In particular, this work includes a Local Representation Formula valid without the symmetry hypothesis. Moreover, it determines a class of domains, called simple, having the following property: every slice regular function on a simple domain can be uniquely extended to the symmetric completion of its domain.

Novel pathway of thymus-dependent NK cell development

Publisher: name: University of British Columbia

description: Natural killer (NK) cells are the major lymphocytes of the innate immune system, but their developmental pathway is not fully defined. It is commonly assumed that all NK cells develop in the bone marrow. In this thesis, I describe a novel thymus-dependent pathway of NK cell development that is specific to those in the thymus and lymph nodes. Microarray analysis revealed TCRγ mRNA expression in NK cells. Genomic and RT-PCR showed that some NK cells have rearranged TCRγ genes while TCRβ and TCRδ genes are in germline order. NK cells with rearranged TCRγ ( Tcrγ⁺ NK cells) were absent in nude mice indicating that they are thymus-dependent. Approximately half of thymus NK cells have rearranged TCRγ genes and in vitro cultures of immature thymocytes (double negative (DN)1 and DN2 progenitors) produced Tcrγ⁺ NK cells, strongly suggesting that these are the thymus-dependent NK cell progenitors in vivo. Thymus NK cells are CD94/NKG2[sup hi] Ly49[sup lo] Mac-1[sup lo] IL-7Rα[sup hi] and they have normal cytotoxicity levels but reduced IFNγ production. By using TCRγ gene rearrangement as a marker of thymus-dependent NK cells, we showed that they are also present in lymph nodes (LNs) but in no other tissues tested. NK progenitors similar to immature thymocytes were found in LNs and LN Tcrγ⁺ NK cells and LN progenitors were also absent in nude mice. In vitro cultures and preliminary in vivo studies suggest that the NK progenitors in the LN give rise to mature NK cells. The results suggest that immature thymocytes migrate to LNs and differentiate into NK cells. It is likely that the thymus-dependent NK cells play a special role in the immune response since their phenotype is unique. Finally, this study suggests that multiple pathways of NK cell commitment exist in multiple tissues. The differences in tissue environment may influence the phenotype and function of NK cells, resulting in multiple subsets of NK cells throughout the body.
Nonequilibrium Theory of Photoinduced Valley Hall Effect

description: A recent scientific debate has arisen: Which processes underlie the actual ground of the valley Hall effect (VHE) in two-dimensional materials? The original VHE emerges in samples with ballistic transport of electrons due to the anomalous velocity terms resulting from the Berry phase effect. In disordered samples though, alternative mechanisms associated with electron scattering off impurities have been suggested: (i) asymmetric electron scattering, called skew scattering, and (ii) a shift of the electron wave packet in real space, called a side jump. It has been claimed that the side jump not only contributes to the VHE but fully offsets the anomalous terms regardless of the drag force for fundamental reasons and, thus, the side-jump together with skew scattering become the dominant mechanisms. However, this claim is based on equilibrium theories without any external valley-selective optical pumping, which makes the results fundamentally interesting but incomplete and impracticable. We develop in this paper a microscopic theory of the photoinduced VHE using the Keldysh nonequilibrium diagrammatic technique and find that the asymmetric skew scattering mechanism is dominant in the vicinity of the interband absorption edge. This allows us to explain the operation of optical transistors based on the VHE.
The Z-graded symplectic Floer cohomology of monotone Lagrangian sub-manifolds

description: We define an integer graded symplectic Floer cohomology and a Fintushel-Stern type spectral sequence which are new invariants for monotone Lagrangian sub-manifolds and exact isotopes. The Z-graded symplectic Floer cohomology is an integral lifting of the usual Z_Sigma(L)-graded Floer-Oh cohomology. We prove the Kunneth formula for the spectral sequence and an ring structure on it. The ring structure on the Z_Sigma(L)-graded Floer cohomology is induced from the ring structure of the cohomology of the Lagrangian sub-manifold via the spectral sequence. Using the Z-graded symplectic Floer cohomology, we show some intertwining relations among the Hofer energy e_H(L) of the embedded Lagrangian, the minimal symplectic action sigma(L), the minimal Maslov index Sigma(L)$ and the smallest integer k(L, phi$ of the converging spectral sequence of the Lagrangian L.

Functional heterogeneity of adult mouse bone marrow hematopoietic stem cells
Creators: name: Dykstra, Bradford John
Publisher: name: University of British Columbia

description: The mammalian blood-forming system sustains physiologically required levels of mature blood cells by supporting their continuous generation from a rare population of undifferentiated, self-sustaining pluripotent hematopoietic "stem" cells (HSCs). Throughout adult life HSCs are located primarily in the bone marrow. Traditionally, the study of HSCs within larger populations of cells has hampered the direct observation of any unique differentiation or self-renewal properties that might distinguish individual members of the HSC compartment. To circumvent this, I analyzed the number and types of progeny generated from single purified HSCs both in cultures initiated with a single cell and in irradiated mice injected with a single cell. In a first set of experiments of this type, I demonstrated that two growth factor cocktails with the same mitogenic and antiapoptotic activity on HSCs in vitro could have remarkably disparate effects on their concomitant self-renewal behaviour, even within the span of a single cell cycle. In addition, I used high-resolution video monitoring of single purified HSCs cultured in microwell arrays to identify cellular features that were associated with HSC self-renewal in vitro. These parameters include longer cell-cycle times than those of their differentiating progeny and an absence of uropodia on the majority of cells within the clone during the final 12 hours of culture. When combined, these parameters improved by a factor of 2-3-fold the identification of clones found to contain daughter HSCs with longterm in vivo reconstituting ability. Finally, from longitudinal and serial WBC analyses performed on a large number of recipients of single purified HSCs, I found that the adult HSC compartment could be resolved into 4 HSC subtypes, 2 of which stably and autonomously propagate their initial unique patterns of WBC reconstitution through many self-renewal divisions in vivo. I also found that, in vitro, HSCs could rapidly acquire less competitive in vivo reconstitution programs although remarkable symmetry was retained in the reconstitution programs acquired by the daughter HSCs generated in the first 4 days in vitro. These findings provide evidence of intrinsically determined heterogeneity in the differentiation and self-renewal properties of individual HSCs.

description: Rural women entrepreneurs in Uganda continue to face multiple challenges that impede their enterprise growth and expansion, despite pragmatic interventions from government and non-state actors to enhance entrepreneurship. Uganda’s female managed nonfarm household enterprises continue to be micro, informal and face bottlenecks to access high credit to grow their business as they do not have the necessary collateral that formal credit institutions demand. Hence, many resort to borrowing from locally managed community or village credit associations to start or grow their businesses and yet, these financing mechanisms are limited. The Uganda Women Entrepreneurship Programme (UWEP) should therefore ensure that the distribution of funds is equitable taking into consideration the heterogeneities across spatial areas, region, education level and size of business enterprise.
