description: The cross section for a Majorana Dark Matter particle annihilating into light fermions is helicity suppressed. We show that, if the Dark Matter is the neutral Majorana component of a multiplet which is charged under the electroweak interactions of the Standard Model, the emission of gauge bosons from the initial state lifts the suppression and allows an s-wave annihilation. The resulting energy spectra of stable Standard Model particles are importantly affected. This has an impact on indirect searches for Dark Matter.

description: Spin-based electronics in topological insulators (TIs) is favored by the long spin coherence1,2 and consequently fault-tolerant information storage. Magnetically doped TIs are ferromagnetic up to 13 K,3 well below any practical operating condition. Here we demonstrate that the long range ferromagnetism at ambient temperature can be induced in Bi2-xMnxTe3 by the magnetic proximity effect through deposited Fe overlayer. This result opens a new path to interface-controlled ferromagnetism in TI-based spintronic devices.

description: We propose a way of enriching the TimeML annotations of TimeBank by adding information about the Topic Time in terms of Klein (1994). The annotations are partly automatic, partly inferential and partly manual. The corpus was converted into the native format of the annotation software GraphAnno and POS-tagged using the Stanford bidirectional dependency network tagger. On top of each finite verb, a FIN-node with tense information was created, and on top of any FIN-node, a TOPICTIME-node, in accordance with Klein's (1994) treatment of finiteness as the linguistic correlate of the Topic Time. Each TOPICTIME-node is linked to a MAKEINSTANCE-node representing an (instantiated) event in TimeML (Pustejovsky et al. 2005), the markup language used for the annotation of TimeBank. For such links we introduce a new category, ELINK. ELINKs capture the relationship between the Topic Time (TT) and the Time of Situation (TSit) and have an aspectual interpretation in Klein's (1994) theory. In addition to these automatic and inferential annotations, some TLINKs were added manually. Using an example from the corpus, we show that the inclusion of the Topic Time in the annotations allows for a richer representation of the temporal structure than does TimeML. A way of representing this structure in a diagrammatic form similar to the T-Box format (Verhagen, 2007) is proposed.

description: We review the evidence for and against the possibility that a strong enough poloidal field stabilizes an axisymmetric magnetostatic field configuration. We show that there does exist a class of resonant MHD waves which produce instability for any value of the ratio of poloidal and toroidal field strength. We argue that recent investigations of the stability of mixed poloidal and toroidal field configurations based on 3-d numerical simulations, can miss this instability because of the very large azimuthal wave numbers involved and its resonant character.

description: The purpose of this research was to explore candidate booster performance metrics that may have the potential to identify less effective booster systems, because current FMVSS No. 213 booster performance requirements can be met without a booster. To provide a more realistic test environment, dynamic testing was performed using a surrogate seat belt retractor on the most recent preliminary design update proposed for the FMVSS No. 213 seat assembly. Given that field data show that belt-positioning boosters are effective at reducing injury risk, potential testing measures were assessed relative to data collected for the no-booster condition. Eleven booster products were evaluated, as well as the no-booster condition, with 6 tests performed using the Hybrid III 10-year-old and 33 tests run with the Hybrid III 6-year-old. Possible metrics associated with good anthropomorphic test device (ATD) kinematics (no submarining or rollout) were the difference between knee and head excursion, maximum torso angle, lumbar spine Moment Z, and lumbar spine Force Y. When testing boosters under more realistic dynamic conditions, the proposed metrics would allow better discernment of less effective boosters, because they differentiate performance relative to the no-booster condition.

description: The $Θ^+$ pentaquark baryon was searched for via the $π^-p\to K^-X$ reaction in a missing-mass resolution of 1.4 MeV/$c^2$(FWHM) at J-PARC. $π^-$ meson beams were incident on the liquid hydrogen target with the beam momentum of 1.92 GeV/$c$. No peak structure corresponding to the $Θ^+$ mass was observed. The upper limit of the production cross section averaged over the scattering angle of 2$^{\circ}$ to 15$^{\circ}$ in the laboratory frame was obtained to be 0.26 $μ$b/sr in the mass region of 1.51$-$1.55 GeV/$c^2$.The upper limit of the $Θ^+$ decay width using the effective Lagrangian approach was obtained to be 0.72 MeV/$c^2$ and 3.1 MeV/$c^2$ for $J^P_Θ=1/2^+$ and $J^P_Θ=1/2^-$, respectively.

description: Das Anlassen von Asynchronmotoren ohne Umrichtertechnik bedeutet eine hohe Strombelastung für das speisende Netz. Es werden im Rahmen dieser Arbeit Maßnahmen (Optimierung des Motors, Sanftstarter, Spartransformator, Schleifringläufer, Schwungradenergiespeicher) detailliert untersucht und im Vergleich zu einem Referenzschiffsbordnetz bewertet, um diese Strombelastung zu reduzieren. Simulationen und messtechnische Untersuchungen zeigen, dass der Einsatz eines Schwungradenergiespeichers eine geeignete Maßnahme darstellt, die installierte Generatorleistung zu reduzieren.
description: Starting asynchronous motors without frequency conversion means drawing high currents from the supply grid. In this thesis several measures (such as motor optimization, soft starters, autotransformers, slip-ring rotors and flywheel energy storage) are investigated and evaluated in comparison to a reference grid from a ship in order to reduce the current loading. Simulations and measured data show that the addition of a flywheel is an appropriate measure for reducing the power demand on the generator.

description: Automated random testing has shown to be an effective approach to finding faults but still faces a major unsolved issue: how to generate test inputs diverse enough to find many faults and find them quickly. Stateful testing, the automated testing technique introduced in this article, generates new test cases that improve an existing test suite. The generated test cases are designed to violate the dynamically inferred contracts (invariants) characterizing the existing test suite. As a consequence, they are in a good position to detect new errors, and also to improve the accuracy of the inferred contracts by discovering those that are unsound. Experiments on 13 data structure classes totalling over 28,000 lines of code demonstrate the effectiveness of stateful testing in improving over the results of long sessions of random testing: stateful testing found 68.4% new errors and improved the accuracy of automatically inferred contracts to over 99%, with just a 7% time overhead.

description: The limit behavior of trajectories of dissipative quadratic stochastic operators on a finite-dimensional simplex is fully studied. It is shown that any dissipative quadratic stochastic operator has either unique or infinitely many fixed points. If dissipative quadratic stochastic operator has a unique point, it is proven that the operator is regular at this fixed point. If it has infinitely many fixed points, then it is shown that $ω-$ limit set of the trajectory is contained in the set of fixed points.

description: Little is known about the relationship between Stay-At-Home orders issued by state governments due to the COVID-19 pandemic and their impacts on motor vehicle-related injuries. The purpose of this study was to determine whether the presence of a Stay-At-Home order was associated with lower rates of motor vehicle-related injuries requiring emergency medical treatment among population sub-groups in West Virginia (i.e., males, females, 0-17, 18-25, 26-45, 46-65, ≥66 years old). A Stay-At-Home order was in effect in West Virginia from March 23-May 4, 2020. Counts of individuals who incurred motor-vehicle-related injuries that required emergency medical treatment were obtained from the Centers for Disease Control and Prevention’s National Syndromic Surveillance Program from January 1 thru September 6 of 2019 and 2020. Counts were obtained by week-year and by population sub-group in West Virginia. The presence of the Stay-At-Home order was binary coded by week. Negative binomial regression was used to assess the relationship between the presence of a Stay-At-Home and injury rates. 2019 population sub-group estimates were obtained from the United States Census Bureau and used as offsets in the models. Models were also adjusted for year and vehicle miles traveled by week-year. There were 23,418 motor-vehicle related injuries during the study period. The presence of the Stay-At-Home order was associated with 44% less injuries overall [Incident Rate Ratio (IRR)=0.56, 95% CI 0.48, 0.64]. Females experienced fewer injuries than males (IRR = 0.49 vs 0.63, respectively) and the number of injuries decreased with age (p-value 0.031) when comparing time periods when the Stay-At-Home was in effect compared to times when it was not. West Virginia’s Stay-At-Home order was associated with lower motor-vehicle injury rates requiring medical treatment across all population sub-groups. Most population sub-groups likely altered their travel behaviors which resulted in lower motor-vehicle injury rates. These findings may inform future policies that impose emergency travel restrictions in populations.

description: The Insurance Institute for Highway Safety (IIHS) introduced its side impact ratings test in 2003. Despite manufacturers' improvements to airbags and vehicle structures, 45% of 2018 side crash fatalities on U.S. roadways were in good-rated vehicles, suggesting that more crashworthiness improvements are necessary. Crash trends indicate that the most promising avenue to address the remaining real-world injuries is a higher severity vehicle-to-vehicle test using a barrier to represent a striking sport-utility vehicle (SUV). Laboratory tests comparing striking SUVs with the current IIHS moving deformable barrier (MDB) showed discrepancies in damage patterns and injury measures. The current study outlines the characteristics of a multi-stiffness aluminum honeycomb barrier to represent a modern SUV-striking vehicle in side impact crash tests. Barrier size and shape were determined from a series of measurements taken from 21 modern SUVs. Barrier honeycomb stiffness characteristics were derived by comparing the damage profile of six different barrier prototypes against a baseline profile obtained from a high-severity SUV crash into a midsize car. Tests were conducted at 60 km/h with a 1,900 kg MDB. The best honeycomb design was tested against four additional vehicles to ensure it was representative of striking SUVs of different sizes and types. The final barrier has a 1,700-mm width by 600-mm height and 500-mm depth multi-stiffness design, with less stiffness on the top and more stiffness in the lower outside sections compared with the original IIHS barrier. For three struck vehicles, the redesigned barrier matched all performance criteria set by the striking-SUV tests. For two additional struck vehicles, there were some differences in intrusion patterns but overall, these matched the test trends of the striking SUVs. The new barrier in a higher severity test mode resulted in a range of performance for these good-rated vehicles. A multi-stiffness aluminum honeycomb barrier was developed to represent the characteristics of striking SUVs in 60 km/h perpendicular side impact crash tests focusing on the occupant compartment. The redesigned barrier differentiates between currently good-rated vehicles, which will promote structural and restraint system improvements to the fleet relevant to the remaining real-world injuries.

description: Securing access to "lead markets" is generally regarded as a key driver for the increasing globalization of innovation since these are considered to be "early indicators" for emerging customer needs. Such markets, therefore, offer a good chance of uncertainty reduction for in the innovation process of firms. Lead markets are generally defined in terms of product segments within national boundaries and are thought to exist in economies with high per capita income, highly sophisticated markets and high international visibility. We argue that there is increasing evidence of lead market tendencies in certain emerging economies, e.g. India. Both domestic and foreign-owned firms there, in recent years, have produced several internationally acclaimed “frugal innovations”, such as the Tata Nano or GE's handheld ECG machine Mac400. Using several examples we demonstrate that India seems to have emerged as a global hub for low-cost, frugal innovations. In this paper, we seek to crystallize the role of lead markets in globalization of R&D and identify the need for an update/extension to better reflect the changed ground realities. On the basis of emerging evidence we propose that sustained economic growth, voluminous markets, strong domestic technological capabilities, presence of foreign-owned R&D, and favorable government policies may be able to offset some of the disadvantages rooted in traditional deficiencies. Engaging a developing country lead market may be useful for firms in securing better access to markets at the bottom of the economic pyramid worldwide.

description: Using numerical calculations, we compare the collective transition probabilities of many spins in random magnetic fields, subject to either frequent projective measurements, frequent phase modulations, or a mix of modulations and measurements. For three different distribution functions (Gaussian, Lorentzian, and exponential) we consider here, the transition probability under frequent modulations is suppressed most if the pulse delay is short and the evolution time is larger than a critical value. Furthermore, decoherence freezing (with a transition rate equals to zero) occurs when there are frequent phase modulations, while the transition rate only decreases when there are frequent measurements and a mix of them, as the pulse delay approaches zero. In the large pulse-delay region, however, the transition probabilities under frequent modulations are enhanced more than those under either frequent measurements or a mix of modulations and measurements.

description: It has been assumed until very recently that all long-range correlations are screened in three-dimensional melts of linear homopolymers on distances beyond the correlation length $ξ$ characterizing the decay of the density fluctuations. Summarizing simulation results obtained by means of a variant of the bond-fluctuation model with finite monomer excluded volume interactions and topology violating local and global Monte Carlo moves, we show that due to an interplay of the chain connectivity and the incompressibility constraint, both static and dynamical correlations arise on distances $r \gg ξ$. These correlations are scale-free and, surprisingly, do not depend explicitly on the compressibility of the solution. Both monodisperse and (essentially) Flory-distributed equilibrium polymers are considered.

description: The post-harvest sector of pomegranate is characterized by its linkages or relationships between producers and consumers as well as between urban and rural areas. And the intermediates operating between the producer and the final buyer play a significant role in regulating these linkages. The functions of intermediaries are buying, selling and risk taking. The costs of fruits are often determined by the performance and efficiency of different intermediaries or functionaries in various marketing channels. The study was conducted in Hiriyuru, Hosdurga and Challakeretaluk of Chitradurga district with a total sample size of 120 comprising 60 growers each under public extension and private extension systems. The harvesting losses faced by the pomegranate growers in public extension are found to be high in Hosadurgataluk (358 Kgs/acre) and In private extension highest harvesting losses was found in Challakeretaluk (290 Kgs/acre). The reasons for the losses attributed in case public extension system were due to disease and rotten (100.00%), whereas in case of private extension services damage due to poor packaging/press is found to be high (88.33%). In public extension the majority (63.33%) of pomegranate growers followed the marketing channel namely producer – market – commission agent – wholesalers – retailer – consumers, whereas, in private extension majority (75.00%) of respondents used marketing channel namely producer – market – commission agent – wholesalers – retailer – consumers.

Mittels Wöhlerversuchen wurde die Ermüdungsfestigkeit von geschweißten Baustählen bei Temperaturen bis -50 °C untersucht. Außerdem werden Auslegungskonzepte für Schweißverbindungen, basierend auf der Hypothese der mikro-strukturellen Stützwirkung, auf die Anwendung bei Minusgrade erweitert.
description: Although it is known that the material properties of steel and its welded joints change with decreasing temperatures, little research has been done on fatigue strength at sub-zero temperatures and design curves and methods for room temperature are also applied to sub-zero temperatures. By means of stress-life (S-N) tests, the fatigue strength of welded structural steels at temperatures down to -50 °C was investigated. In addition, fatigue design concepts for welded joints - based on the micro-structural support effect hypothesis - are extended to sub-zero temperatures.

description: The observation study sought to explore the influencing factors associated with mobile phone use when e-cyclists were waiting for red lights at intersections, which provided a theoretical foundation for solving the potential traffic threat and developing management plans for e-cyclists. Data regarding e-cyclists were collected through camera conducted at the entrance of multiple intersections in Zhenjiang, China in July 2020. The data was reviewed by playing frame by frame. A statistical analysis was performed with the statistical package SPSS software. After conducting univariate logistic analysis on study variables, the multivariate analysis was adopted based on the binary logit regression model. Among the 1166 e-cyclists observed, 15.01% (n = 175) e-cyclists had operated their mobile phones while waiting for red lights. Young e-cyclists, delivery cyclists were more likely to be involved with mobile phone use. Furthermore, mobile phone use was more observed at intersections in suburban areas and with long waiting time. E-cyclists, who was carrying a child, rarely used mobile phone. All intersections during off-peak times showed an increase in mobile phone use. The results also show that neither e-cyclists themselves nor traffic managers are aware of the risks of mobile phone use and the impact on traffic safety while waiting for a red light. The findings of this research revealed the factors influencing mobile phone use of e-cyclists while waiting for a red light, and indicated that education and behavioral intervention need to be strengthened to improve riding safety at intersections. These results will be helpful in developing programs of electric bicycle management.

description: We consider a coarse graining of NN interactions in coordinate space very much in the spirit of the well known Vlowk approach. To this end we sample the interaction at about the minimal de Broglie wavelength probed by NN scattering below pion production threshold. This amounts to provide a simple delta-shell potential plus the standard OPE potential above 2 fm. The possible simplifications in the Nuclear many body problem are discussed.

Enhancing Public Reputation Systems: Trust Scaling to Mitigate Voter Subjectivity
Creators: name: IJCSIT
Publisher: name: Zenodo
Year: 2025

description: In the digital age, the reliability of public reputation systems is increasingly challenged by the subjectivity of voter assessments. This paper presents a novel public reputation estimation method that leverages a scaling trust framework to mitigate the influence of individual biases and enhance the accuracy of reputation scores. We propose a scaling mechanism that adjusts the weight of each voter’s input according to their trustworthiness, thereby reducing the impact of outlier opinions and fostering a more balanced representation of public sentiment. The experiment results demonstrate that our method significantly improves the robustness and fairness of reputation estimations compared to traditional models.
Process engineering of ceramic composites and coatings modified with chemically bonded composite sol-gel
Creators: name: Yao, Yu Chen
Publisher: name: University of British Columbia

description: This work explores the possibilities of the application of chemical bonding to process ceramic-ceramic composites by employing ceramic sol-gel as the core processing technique. The principal rationale is that chemical bonding produces ceramic bond at substantially lower temperatures under 600°C, opening new processing possibilities. Versatility of the chemically bonded composite sol-gel alumina is demonstrated by the two final product forms: coatings and wear resistant composites. In Thermal Barrier Coating (TBC) application, an additional ceramic layer is sandwiched between two layers of Plasma Sprayed TBC, to improve overall thickness and thermal insulation. Such combination creates an unique Hybrid Thermal Barrier Coating (HTBC) with the chemically bonded ceramic layer ranging between 200-500μm between two ~100μm traditional air plasma sprayed barrier films. The HTBC has dual microstructure, adjustable porosity and varying composition, including alumina and yttria stabilized zirconia. The chemically bonded ceramic layer provides vertical microstructure beneficial in enhancing thermal strain tolerance. Thermal cyclic tests (30-1050 °C) showed good performance of the hybrid coating up to 1000 cycles. In the Carbon-Carbon Composites (CCC), pores are infiltrated with alumina particles, which are hardened to a wear resistant phase through chemical bonding. The infiltration process is facilitated by vacuum impregnation followed by heat treatment in air at 300-500°C, to create a Ceramic Carbon-Carbon Composite (C⁴). Meanwhile, the infiltration also achieves densification at rate faster than traditional Chemical Vapour Infiltration (CVI) process. The time saving of ceramic vacuum impregnation process compared to the tradition CVI promises significant reduction of the processing costs, possibly up to a factor of 10 (from the current ~$1,000/kg, to the target ~$100/kg). The CCC as high performance light weight braking pads are almost exclusively used in aerospace and racing vehicles due to prohibitively high cost. The faster vacuum impregnation process could potentially migrate the C⁴ to general automotive applications. The C⁴ were tested for abrasive and sliding wear resistance. The results show a reduction in volume loss as compared to similar porosity CCC. The process of chemically bonding alumina-based ceramics is thus effective in introducing alumina-based ceramic composite phase to both a coating system and a porous monolith ceramic.

description: Das Tragverhalten extern vorgespannter Segmentbrücken unterscheidet sich aufgrund der unbewehrten Fugen zwischen den Fertigteilen grundlegend von dem monolithischer Tragwerke. Anhand von Versuchen und numerischen Simulationen wird das Trag- und Verformungsverhalten von Trockenfugen studiert. Weiterhin wird ein neues Bemessungsmodell vorgeschlagen.
description: Segmental box girder bridges externally post-tensioned consist in contrast to ‘classical’ monolithic constructions of 'small' precast elements stressed together by external tendons. Although many segmental bridges had been built so far the design of the unreinforced joints between the segments, which is of critical importance regarding the safety of the structure, is still under discussion. Therefore numerical calculations had been conducted and verified by full-scale tests. Based on this investigations, a new design model is proposed.
An Information Theoretic Location Verification System for Wireless Networks

description: As location-based applications become ubiquitous in emerging wireless networks, Location Verification Systems (LVS) are of growing importance. In this paper we propose, for the first time, a rigorous information-theoretic framework for an LVS. The theoretical framework we develop illustrates how the threshold used in the detection of a spoofed location can be optimized in terms of the mutual information between the input and output data of the LVS. In order to verify the legitimacy of our analytical framework we have carried out detailed numerical simulations. Our simulations mimic the practical scenario where a system deployed using our framework must make a binary Yes/No "malicious decision" to each snapshot of the signal strength values obtained by base stations. The comparison between simulation and analysis shows excellent agreement. Our optimized LVS framework provides a defence against location spoofing attacks in emerging wireless networks such as those envisioned for Intelligent Transport Systems, where verification of location information is of paramount importance.

Recognizing recurrent neural networks (rRNN): Bayesian inference for recurrent neural networks

description: Recurrent neural networks (RNNs) are widely used in computational neuroscience and machine learning applications. In an RNN, each neuron computes its output as a nonlinear function of its integrated input. While the importance of RNNs, especially as models of brain processing, is undisputed, it is also widely acknowledged that the computations in standard RNN models may be an over-simplification of what real neuronal networks compute. Here, we suggest that the RNN approach may be made both neurobiologically more plausible and computationally more powerful by its fusion with Bayesian inference techniques for nonlinear dynamical systems. In this scheme, we use an RNN as a generative model of dynamic input caused by the environment, e.g. of speech or kinematics. Given this generative RNN model, we derive Bayesian update equations that can decode its output. Critically, these updates define a 'recognizing RNN' (rRNN), in which neurons compute and exchange prediction and prediction error messages. The rRNN has several desirable features that a conventional RNN does not have, for example, fast decoding of dynamic stimuli and robustness to initial conditions and noise. Furthermore, it implements a predictive coding scheme for dynamic inputs. We suggest that the Bayesian inversion of recurrent neural networks may be useful both as a model of brain function and as a machine learning tool. We illustrate the use of the rRNN by an application to the online decoding (i.e. recognition) of human kinematics.

description: The student movement back in the 1970s was very active mainly due to political life stagnation, lack of progress regarding the national question (Israeli occupation of Sinai), and generally worries of the public after the 1967 defeat. Here I explore the experience of one of the students of that critical period, Dr. Sameh, an engineer who attended university in Egypt as an undergraduate student during the 1970s pre-war period.

Lambda^{QCD}_{MS} from Renormalization Group Optimized Perturbation

description: A recent extension of a variationally optimized perturbation, combined with renormalization group properties in a straightforward way, can provide approximations to nonperturbative quantities such as the chiral symmetry breaking order parameters typically. We apply this to evaluate, up to third order in this modified perturbation, the ratio Fpi/Lambda, where Fpi is the pion decay constant and Lambda the basic QCD scale in the modified MS scheme. Using experimental Fpi input value we obtain Lambda(nf=2) ~ 255_{-15}^{+40} MeV, where quoted errors are estimates of theoretical uncertainties of the method. This compares reasonably well with some recent lattice simulation results. We briefly discuss prospects (and obstacles) for extrapolation to alpha_S(mu) at perturbative mu values.

Hyper-lignified root systems as a carbon sink in Arabidopsis thaliana
Creators: name: Nye, Adrienne Juliana
Publisher: name: University of British Columbia
Year: 2009

description: Lignified plant cell walls represent an immense carbon sink to offset rising atmospheric carbon dioxide (CO₂) due to the chemical stability and structural diversity of the bonds formed between lignin subunits, making it the slowest decomposing component of dead vegetation. This thesis explores the feasibility of increasing lignin deposition in roots through overexpression of SND1 (Secondary Wall Associated NAC Domain Protein 1), a key transcriptional activator involved in regulating secondary wall biosynthesis in fibres, under the control of two different putative root-specific promoters, 4-coumarate:CoA ligase 1 (4CL1) and glutathione S-transferase-tau class 19 (GSTU19). Transgenic plants were analyzed at: 1) the molecular level (transcription of lignin pathway genes and regulatory transcription factors (TFs) involved in cell wall biosynthesis), 2) the chemical level (lignin content) and 3) the plant growth and development level (phenotyping and microscopy). Results showed that: i) SND1 was overexpressed in a tissue-specific manner in roots, ii) SND1 overexpression caused an upregulation of its previously known direct downstream targets, iii) SND1 overexpression did not result in a modification of indicative lignin biosynthetic pathway genes in roots, iv) plants overexpressing SND1 in roots generally produced plants with decreased total lignin content, v) plants overexpressing SND1 in roots generally showed an increase in lateral root density, and vi) seed traits, plant growth and development, plant height and lignin deposition patterns in roots remained unaltered. Misregulation of SND1 in roots did not result in the predicted increase in lignin deposition patterns in this organ.
Real Democracy The True Direction For Sustainable Development In Africa

description: Africa is an underdeveloped continent. Africa has the world’s poorest population and the most ill and food insecure. Its GDP have stayed the same for decades or at best increase slightly while other continents, developed and developing, have skyrocketed in global economic competiveness. A noteworthy characteristic of the continent is the “habit” of military coups (especially post-independence) and high levels of government corruption. Is democracy a prerequisite for development in Africa or can authoritarian regimes sustain a reasonably stable development state regardless of ever going towards a democracy? In this paper, I argue that it is definitely the earlier case.
