Quantifying Entrepreneurial Networks: Data Collection in Addis Ababa, Ethiopia

Abstract : Sociologists, economists, and network scientists concur that the entrepreneur s network is critical to success but have consistently struggled with developing models that are measurable or quantifiable. Well-known research on this subject tends to focus on the entrepreneur s social network (Greve and Salaff, 2003, Witt,1978) and utilizes the Name Generator approach (McAllister and Fischer,1978) to develop the social network model. This method maps an ego-centered network and assembles an inventory of information about every social contact, such as the relationship between the person under analysis and the people within the social network (Van Der Gaag & Snijders, 2004).
STOC: Energy Cost Models of Smartphones for Task Offloading to the Cloud

Improving computing ability of smartphones and also prolonging their battery life can be achieved by offloading the task to the cloud. However, task offloading introduces a communication cost for those devices. Therefore, consideration of the communication cost is crucial for the effectiveness of task offloading. To make task offloading beneficial, one of the challenges is to estimate the energy consumed in communication activities of task offloading. Accurate energy estimation models will enable these devices to make the right decisions as to whether or not to perform task offloading, based on the energy cost of the communication activities. If the offloading process consumes less energy than processing the task on the device itself, then the task is offloaded to the cloud Here energy models during task offloading can be constructed during both uploading and downloading process using 3G/4G and Wifi. Also an analysis report is prepared giving detailed information of the energy consumed during uploading and downloading video files. Storage as a service (SaaS) aspect of the cloud is utilized for task offloading.
Extended Distal Pancreatectomy for Cancer of the Body and Tail of the Pancreas: Analysis of Early and Late Results

Cancer of the body-tail of the pancreas often involves adjacent structures. Thus, surgical treatment may be extended to other organs or vessels in order to achieve radical resection. The aim of this study is to evaluate the safety and efficacy of extended distal pancreatectomy for ductal adenocarcinoma of the body and tail of the pancreas. Between January 2000 and December 2016, 101 patients underwent distal pancreatectomy (DP) for pancreatic cancer: 65 patients underwent standard-DP and 36 extended-DP, including the resection of the partial stomach (n = 12), adrenal gland (n = 7), liver (n = 7), colon (n = 8), celiac axis (n = 6), portal vein (n = 5), jejunum (n = 4) and kidney (n = 4). The two groups were compared in terms of their TNM classification, pathological grade, nodal status, state of resection margins, age, sex and levels of preoperative serum carbohydrate antigen 19-9 (CA 19.9). The morbidity and mortality were not statistically different in the two groups. The two groups disease-free and overall survival rates were significantly influenced by the tumor’s stage, nodal status, pathological features and resection margins. Survival was not influenced by the extent of the surgical resection. However, when patients were stratified according to the type of extended resection, survival was worse in the group of patients undergoing vascular resection. Multivariate analysis showed that the stage and resection margins are independent predictors of disease-free and overall survival. Extended distal pancreatectomy may be performed with acceptable morbidity and mortality rates. Survival is not significantly different after standard or extended resection. However, the rate of tumor recurrence is high, and long-term survival is a rare event, especially in those patients who undergo distal pancreatectomy associated with vascular resection.
Evaluate the Expressions of Compression Strength and UPV Relationship

Plans and implementation of various projects depend on the availability of construction materials, despite of the evolution of building materials used over time. [2] The concrete material still occupies on top ranking applications and its developed and improved production of concrete, dramatically with various types of concrete demand such as, foam concrete, sustainable concrete and other related material. [3] There were many uses of concrete in the construction field, and there were various types of test methods. The traditional test (Compression test) for cubes of concrete does not fit with the modern types of concrete, also it does not provide enough indicators of the quality of the concrete in terms of loading and permanence outward appearance, therefore researchers’ efforts went to investigate new types of tests could diagnose the validity of concrete very quickly. Non-destructive tests NDT are used to determine the properties of concrete in the lab or in-situ without damaging the constructed members. The UPV is commonly used to locate the cracks, voids, steel reinforcement and cover concrete. UPV and Schmidt hammer are used to evaluate the structures initially before going with another accurate method. [4] This study contributes to a better understanding of a direct UPV method in concrete, and to widespread the technique with more confidence. A more relationship between UPV and fcu was found. Due to the lack or research area of understanding the direct method of UPV in concrete strength, therefore this research paper will be mainly emphasized on expressions of compression strength and UPV relationship.
Comparison Between Dielectric Inversion Results from Synthetic Aperture Radar Co-and Quad-Polarimetric Data via a Polarimetric Two-Scale Model

— In this study we compare the retrieval results for the dielectric properties of verified oil slick, acquired using airborne multifrequency synthetic aperture radar. A polarimetric two-scale model was used to invert the radar imagery by first employing solely the co-polarization channels, and then by employing the co-polarization channels in conjunction with the cross-polarization channels, and thereby employing the full suite of polarization information available. The goal is to show that the inversion results obtained from both methods are consistent. Given that the ocean surface is a highly non-depolarizing surface scatter, the signal return within the cross-polarization channels is usually negligible and of no practical use when trying to invert the returned backscatter into useful quantities such as the dielectric constant. In this paper, we employ F-SAR data, which was acquired in X, S-and L-bands and has an extremely low noise floor, implying that the cross-polarization ratio can be employed. A signal-to-noise analysis showed that only the L-band acquisitions were suitable for analysis in this paper. The retrieval results are comparable for the two methods in the case of low dielectric values.
Proof nets for unit-free multiplicative-additive linear logic (extended abstract)

A cornerstone of the theory of proof nets for unit-freemultiplicative linear logic (MLL) is the abstract representation of cut-freeproofs modulo inessential commutations of rules. The only knownextension to additives, based on monomial weights, fails topreserve this key feature: a host of cut-free monomial proof nets cancorrespond to the same cut-free proof. Thus the problem offinding a satisfactory notion of proof net for unit-freemultiplicative-additive linear logic (MALL) has remained open since theincep-tion of linear logic in 1986. We present a new definition of MALLproof net which remains faithful to the cornerstone of the MLLtheory.
Patients’ Satisfaction With the Quality of Services at Primary Healthcare Centers in Saudi Arabia

Background: Patients’ satisfaction is an essential indicator used to measure the quality of healthcare services. The evaluation of patients’ satisfaction with primary healthcare center (PHC) visits is therefore essential when it comes to assessing the quality of healthcare services provided. Aim: To assess patients’ overall satisfaction with the quality of services provided at PHCs in different regions of Saudi Arabia. Methods: A retrospective cross-sectional study was conducted using secondary data collected from 2,390 PHCs in different regions of Saudi Arabia. Data were collected by the Patient Experience Measurement Program in the Ministry of Health (MOH) using the Press Ganey Survey from January 2022 to December 2022. The Press Ganey Survey is a standardized tool used by the Saudi MOH to assess patients’ satisfaction with the health services provided in different specialties and healthcare facilities. The assessment tool (Press Ganey survey) involves six domains (Access, Moving through, Nurse, Care provider, Personal issue, and Overall assessment). The data were tabulated and analyzed using the Statistical Package for the Social Sciences (SPSS). Results: In total, there were 536,406 study participants, with their mean age being 28.7±21.1. The overall patients’ satisfaction score was 4.2 out of 5 (83.8%). Male participants reported more satisfaction with PHC services than did females (86.6%, 81%), respectively. The domain with the highest patients’ satisfaction scores was that of the Care provider (84.8%), while the domain with the lowest rating was Moving through (82.8%). Conclusion: This baseline study found that patients were generally satisfied, with the highest levels of satisfaction with their care providers, highlighting the crucial role of professionals in the patient experience. Further research is recommended to give a more in-depth analysis and thus highlight additional correlating and predicted elements of patients' satisfaction with PHC treatments in Saudi Arabia.
Metabolic profile of blood serum in experimental arterial hypertension

The etiology of essential hypertension is intricate, since it employs simultaneously various body systems related to the regulation of blood pressure in one way or another: the sympathetic nervous system, renin-angiotensin-aldosterone and hypothalamic-pituitary-adrenal systems, renal and endothelial mechanisms. The pathogenesis of hypertension is influenced by a variety of both genetic and environmental factors, which determines the heterogeneity of the disease in human population. Hence, there is a need to perform research on experimental models – inbred animal strains, one of them being ISIAH rat strain, which is designed to simulate inherited stress-induced arterial hypertension as close as possible to primary (or essential) hypertension in humans. To determine specific markers of diseases, various omics technologies are applied, including metabolomics, which makes it possible to evaluate the content of low-molecular compounds – amino acids, lipids, carbohydrates, nucleic acids fragments – in biological samples available for clinical analysis (blood and urine). We analyzed the metabolic profile of the blood serum of male ISIAH rats with a genetic stress-dependent form of arterial hypertension in comparison with the normotensive WAG rats. Using the method of nuclear magnetic resonance spectroscopy (NMR spectroscopy), 56 metabolites in blood serum samples were identified, 18 of which were shown to have significant interstrain differences in serum concentrations. Statistical analysis of the data obtained showed that the hypertensive status of ISIAH rats is characterized by increased concentrations of leucine, isoleucine, valine, myo-inositol, isobutyrate, glutamate, glutamine, ornithine and creatine phosphate, and reduced concentrations of 2-hydroxyisobutyrate, betaine, tyrosine and tryptophan. Such a ratio of the metabolite concentrations is associated with changes in the regulation of glucose metabolism (metabolic markers – leucine, isoleucine, valine, myo-inositol), of nitric oxide synthesis (ornithine) and catecholamine pathway (tyrosine), and with inflammatory processes (metabolic markers – betaine, tryptophan), all of these changes being typical for hypertensive status. Thus, metabolic profiling of the stress-dependent form of arterial hypertension seems to be an important result for a personalized approach to the prevention and treatment of hypertensive disease.
Flux Observer Based on Enhanced Second-Order Generalized Integrator With Limit Cycle Oscillator for Sensorless PMSM Drives

In a position sensorless permanent magnet synchronous motor (PMSM) drive system, parameter mismatch will introduce estimation error in the stator flux and rotor position information. A novel flux observer based on an enhanced second-order generalized integrator (SOGI) with a limit cycle oscillator is proposed to improve the robustness of sensorless PMSM drives. Based on the SOGI structure, the proposed method constructs a nonlinear oscillator with a self-excited oscillation function that can maintain the flux trajectory oscillation even in the absence of the input stator electromotive force. The enhanced observer can converge the stator flux trajectory to its expected state under external disturbances and reduce position estimation error. Moreover, the proposed limit cycle oscillator can improve the harmonic suppression ability of the SOGI-based flux observer. The convergence and robustness of the enhanced observer are both investigated, demonstrating that the proposed method can improve the performance of the flux observer. The effectiveness of this method is verified by experiments on a 2.2-kW PMSM drive platform.
Determinants of Food Security in Selected Agro-pastoral Communities of Somali and Oromia Regions, Ethiopia

In spite of receiving a significant amount of food aid, achieving food security has been a major problem in Ethiopia. The claim is evidenced from the 2010 Global Hunger Index where the country fared dismally, coming only fourth from the bottom. There are several factors attributing to this problem of food insecurity in a country like Ethiopia which depends highly on agriculture and allied activities. Some of the factors can be linked to low food production and productivity thereby leading to pervasive poverty. In order to assess these factors, the study was conducted on some selected members of agro-pastoral communities of Somali and Oromia regions in Ethiopia. Using availability of food in the household for the last one month as a proxy for food security, the estimated results of a logistic regression model indicated that the most significant factors affecting household food security are educational level of the spouse and that of the household head, size of farm land, availability of household assets including livestock, peace and security. The paper suggests some leads to how these amenities and resources can be provided to household members as they endeavor to reduce food insecurity.
Distinct wind convergence patterns due to thermal and momentum forcing of the low level jet into the Mexico City basin

Mexico City lies in a high altitude basin where air quality and pollutant fate is strongly influenced by local winds. The combination of high terrain with weak synoptic forcing leads to weak and variable winds with complex circulation patterns. A low level jet entering the basin in the afternoon leads to very different wind convergence lines over the city depending on the meteorological conditions. Surface and upper-air meteorological observations are analysed during the MCMA-2003 field campaign to establish the meteorological conditions and obtain an index of the strength and timing of the jet. A mesoscale meteorological model (MM5) is used in combination with high-resolution satellite data for the land surface parameters and soil moisture maps derived from diurnal ground temperature range. A simple method to map the lines of wind convergence both in the basin and on the regional scale is used to show the different convergence patterns according to episode types. The low level jet is found to occur on most days of the campaign and is primarily due to thermal forcing which is very similar from day to day. Momentum mixing from winds aloft into the surface layer is much more variable and can determine both the strength of the jet and the pattern of the convergence zones. Northerly flows aloft lead to a weak jet with an east-west convergence line that progresses northwards in the late afternoon and early evening. Westerlies aloft lead to stronger jets and a north-south convergence line through the middle of the basin starting in the early afternoon. Improved understanding of basin meteorology will lead to better air quality forecasts for the city and better understanding of the chemical regimes in the urban atmosphere.
CLASSIFICATION OF SOME COMMERCIAL LINGZHI (Ganoderma spp.) ACCESSIONS IN VIETNAM BY ITS-BASED DNA BARCODE Phân loại một số mẫu lingzhi thương mại (Ganoderma spp.) tại Việt Nam theo mã vạch DNA dựa trên vùng đệm sao chép nội

In Vietnam, lingzhi is mainly used for medicinal purposes with a high market value leading to the increasing production in recent years. However, the identification and classification of this fungus are inaccurate due mainly to morphological characteristics. In this study, the ITS-based DNA barcode was used to analyze the genetic composition of 10 commercial lingzhi genotypes collected from different regions across the country. The results show that there exists genetic diversity of 10 lingzhi samples. Based on Kimura 2-parameter model, the genetic distances among studied accessions range from 0.000 to 0.047. Seven of ten accessions were reclassified as G. lingzhi and three accessions were identified as G. lucidum. In addition, 19 nucleotide sites differed among fungal samples were also reported. There is a high potential of using ITS-based DNA barcode for the identification and classification as well as providing information on the genetic relationship between lingzhi varieties.
Phytochemical Analysis of Cleome viscosa Active Polyphenolic Compounds Possessing Antidiabetic Activity

Background: The counteractive action of diabetes by plant polyphenols along with their utilization in the treatment of diabetic difficulties is of expanding significance from the epidemiological information with in vitro and in vivo examinations. Objectives: We assessed the antihyperglycemic impacts of methanolic (MeCV), aqueous (AqCV), ethyl acetate (EaCV) and n-hexane (NhCV) extracts of Cleome viscosa whole plant. Materials and Methods: Qualitative phytochemical analysis and antidiabetic activities by glucose diffusion, inhibitory movement of starch processing enzymes i.e. α -glucosidase and α -amylase, glucose uptake by yeast cell method and also the non-enzymatic action (glycosylation of Hb). The identification of polyphenols in bioactive extracts was categorized by using HPLC/UV. Results: To evaluate the comparative power of these extracts, the concentrations required for 50% and 100% inhibition of enzyme movement were resolved. Greatest enzyme inhibition was utilized to evaluate an inhibitor’s relative viability. Results demonstrated that MeCV strongly diffused by glucose and inhibited both α -glucosidase and α -amylase enzyme movement and great impact on the glucose uptake by yeast cells and non-enzymatic glycosylation of Hb with equivalent intensity respectively than acarbose. While NhCV was showed less impact on glucose diffusion, α -glucosidase, α -amylase, glucose uptake by yeast cells and glycosylation of Hb. Gallic acid (2.45%), protocatechuic acid hexoside (0.83%), chlorogenic acid (0.77%), catechin (0.53%), quercetin (0.80%), p-hydroxybenzoic acid (0.78%), and p-coumaric (0.07%) were the main compounds of the MeCV. Conclusion: Based on our results we concluded that the MeCV firmly impacts on enzymatic and non-enzymatic activities due to rich content of polyphenols present in MeCV.
Chapter 22 LFG and Tree-Adjoining Grammar

This chapter gives an introduction to Tree-Adjoining Grammar (TAG) and draws some comparisons with Lexical Functional Grammar (LFG). It is primarily aimed at those familiar with LFG who are looking to learn about TAG and see where the two formalisms differ/overlap, but the comparisons will also be of interest to those coming from a TAG background. After introducing TAG, the chapter considers questions of generative capacity, lexicalisation, and the factoring of redundancies from grammars. It then concludes by illustrating the potential for combining LFG and TAG, and discusses the theoretical implications of doing so.
Regeneration of Athrotaxis selaginoides and other rainforest tree species on landslide faces in Tasmania

Seedling surveys indicated that landslide faces provide opportunities for Athrotaxis selaginoides and Nothofagus cunninghamii to regenerate in thamnic and high altitude callidendrous rainforest. The spatial distribution of mature A.selaginoides stems at some sites suggests that they have originated on past landslides. Leptospermum scoparium and Eucalyptus vernicosa seedlings were also present at some of the sites investigated. Therefore, landslides may provide regeneration opportunities for these species in rainforest communities in the absence of fire. The physical attributes of A. selaginoides suggest that the species would be advantaged by canopy disturbance of the scale caused by landslides as opposed to smaller treefall gaps. The cooler climate, higher levels of slope instability, avalanches and snowstorms during the last glacial would have been well suited to this species.
A unified accretion-ejection paradigm for black hole X-ray binaries. VI. Radiative efficiency and radio-X-ray correlation during four outbursts from GX 339-4

The spectral evolution of transient X-ray binaries can be reproduced by an interplay between two flows separated at a radius $R_J$: a standard accretion disk (SAD) in the outer parts and a jet-emitting disk (JED) in the inner parts. In the previous papers of this series, we recover the spectral evolution in both X-rays and radio for four outbursts of GX339-4 by playing independently with the two parameters: $R_J$ and the accretion rate $\dot{M}_{in}$. In this paper, we compare the time evolution of $R_J$ and $\dot{M}_{in}$ for the four outbursts. We show that despite the undeniable differences between the time evolution of each outburst, a unique pattern in the $\dot{M}_{in}-R_J$ plane seems to be followed by all cycles within the JED-SAD model. We call this pattern a fingerprint, and show that even the 'failed' outburst considered follows it. We also compute the radiative efficiency in X-rays during the cycles and consider its impact on the radio--X-ray correlation. Within the JED-SAD paradigm, we find that the accretion flow is always radiatively efficient in the hard states, with between $15\%$ and $40\%$ of the accretion power being radiated away at any given time. Moreover, we show that the radiative efficiency evolves with the accretion rate because of key changes in the JED thermal structure. These changes give birth to two different regimes with different radiative efficiencies: the thick disk and the slim disk. While the existence of these two regimes is intrinsically linked to the JED-SAD model, we show direct observational evidence of the presence of two different regimes using the evolution of the X-ray power-law spectral index, a model-independent estimate. We then argue that these two regimes could be the origin of the gap in X-ray luminosity in the hard state, the wiggles and different slopes seen in the radio--X-ray correlation, and even the existence of outliers.
COMPARING WEALTH EFFECTS : THE STOCK MARKET VERSUS THE HOUSING MARKET

We examine the link between increases in housing wealth, financial wealth, and consumer spending. We rely upon a panel of 14 countries observed annually for various periods during the past 25 years and a panel of U.S. states observed quarterly during the 1980s and 1990s. We impute the aggregate value of owner-occupied housing, the value of financial assets, and measures of aggregate consumption for each of the geographic units over time. We estimate regressions relating consumption to income and wealth measures, finding a statistically significant and rather large effect of housing wealth upon household consumption.
