description: Introduction: Psychotraumatic disorders, particularly post-traumatic stress disorder (PTSD), have been a major public health issue for many years. However, many patients remain resistant to treatment, with significant levels of residual symptoms, a high dropout rate, and poor functional prognosis despite a reduction in psychotraumatic symptoms. The physical impact of trauma might influence treatment response. We have developed an integrative method for patients suffering from post-traumatic stress disorder (PTSD). In this study, we report the cases of 16 successive patients with PTSD treated with adjunct psychomotor trauma exposure. Methods: The data were collected retrospectively from the clinical records of subjects treated with adjunct psychomotor exposure therapy at the Hauts-de-France Regional Center for Psychotrauma. Severity of psychotrauma was reported using PCL-5 before and one month after treatment. Results: A decrease in PCL-5 score was seen in all participants between baseline (45.6 ± 11.6) at the end of treatment (16.6 ± 10.1) (p < .001). Conclusion: Adjunct psychomotor exposure therapy is a promising tool for the treatment of PTSD. Future high-quality randomised controlled trials are necessary. We have developed an integrative method for patients suffering from post-traumatic stress disorder.In this study, we report the cases of 16 successive patients with PTSD treated with adjunct psychomotor trauma exposure.A decrease in PCL-5 score was seen in all participants between baseline and the end of treatment.

description: We consider the minimum mass planet, as a function of radius, that is capable of opening a gap in an $α$-accretion disk. We estimate that a half Jupiter mass planet can open a gap in a disk with accretion rate $\dot M \la 10^{-8} M_\odot$/yr for viscosity parameter $α=0.01$, and Solar mass and luminosity. The minimum mass is approximately proportional to $\dot M^{0.48} α^{0.8} M_*^{0.42} L_*^{-0.08}$. This estimate can be used to rule out the presence of massive planets in gapless accretion disks. We identify two radii at which an inwardly migrating planet may become able to open a gap and so slow its migration; the radius at which the heating from viscous dissipation is similar to that from stellar radiation in a flared disk, and the radius at which the disk has optical depth order 1 in a self-shadowed disk. If a gap opening planet cuts off disk accretion allowing the formation of a central hole or clearing in the disk then we would estimate that the clearing radius would approximately be proportional to the stellar mass.

description: The anti-corrosion ability for PV framing materials is proposed in standard of International Electrotechnical Commission (IEC) 61701: 2011 Severity 6. It is used to understand the resistance of different PV modules to corrosion from salt mist containing Cl- (NaCl, MgCl2, etc.). The test is applied in a neutral salt mist condition of around pH 6.5~7.2, and the criteria for the test is the PV power degradation less than 5 %. According to the experiences, most PV frames can withstand the corrosion condition and pass the test without power losses and insulation failure. To simulate the real application of the environment of acid rain and cycling condition, copper accelerated acetic acid salt spray (CASS) test referred to ASTM B368 is performed to study the resistance of PV frames. In the current research, we report the corrosion behavior of various commercial anodized Al materials undergoing CASS test. Some blue crystalline salts depositing on the sample surfaces due to the copper ions. And the fluorocarbon-coated type generally shows a smooth surface without corroded pits, while the commercial anodized Al materials were detected some pits and uniform corrosion on the surface. And the non-coated Al counterpart was revealed a poor resistance that lots pits and layers peeled from the surfaces. According to the test, it is confirmed that the CASS test can be applied for fast screening the corrosion resistance of PV Al frames. A detailed research results by metallurgical procedure will be revealed for discussion.

description: We present preliminary results from spectral observations of four candidate radio sources co-identified with known planetary nebulae (PNe) in the Small Magellanic Cloud (SMC). These were made using the Radcliffe 1.9-meter telescope in Sutherland, South Africa. These radio PNe were originally found in Australia Telescope Compact Array (ATCA) surveys of the SMC at 1.42 and 2.37 GHz, and were further confirmed by new high resolution ATCA images at 6 and 3 cm (4"/2"). Optical PNe and radio candidates are within 2" and may represent a subpopulation of selected radio bright objects. Nebular ionized masses of these objects may be 2.6 MSol or greater, supporting the existence of PNe progenitor central stars with masses up to 8 MSol.

description: France aims to boost the share of solar power generation in its electricity mix by 2030. When PV selfconsumption systems become economically competitive, end-users will be willing to switch to PV self-consumption instead of using power from the grid. However, high penetration of distributed solar PV provokes a significant impact on the stability of electricity. The major systemic issues concern seasonal back-up power system associated with variable PV integration. Policymakers thus need to work on systemic solutions (e.g. load management, peak shaving) to support the large-scale integration of variable solar power. In this regards, this study aims to propose an innovative load management model based on the strategic secondary application of residential batteries already installed for PV self-consumption. We performed a prospective economic analysis to identify potential system contribution of French residential PV-battery systems in 2030. The aim is to reduce systemic impact of distributed solar PV system integration strategically thanks to collective use of distributed residential batteries for load management when they are not in use in winter. A sensitivity analysis has been conducted based on different projections of residential PV self-consumption in 2030 (RTE, Enedis). Our study then concludes with key messages and policy recommendations.

description: Excerpts from the report: The Democratic Republic of the Congo (Kinshasa) is gaining momentum in its economic recovery from the turmoil following independence from Belgium in 1960. Civil and political disorders had reduced total agricultural production about one-fourth from the 1959 high to the 1965 low. Since 1965, production has slowly recovered. This recovery can be attributed to political stability and gradual restoration of internal security, plus monetary reform in June 1967 (primarily devaluation), which increased incentives to produce and export. Palm products, coffee, and rubber are the main agricultural exports. Tea and cocoa beans are also export crops, but of lesser importance. The main food crops (cassava, plantains, sweetpotatoes , and corn) of the subsistence farmer have risen in production from low points in the early sixties to levels almost equal to those prevailing before independence.

description: Whether solar panels installed in the coastal area would suffer more severe PID phenomenon due to the salt spray environment or not was one of controversial debate topics recently. The sequence tests taken in past studies had not found decisive evidence to exclude or confirm the impact of external ions on PID effect. In view of this, the epoxy substrate covering on the special cell-scale module-like specimen was prepared to simulate the source of impurities in the coastal environment during PID test. Significant change in shunting degradation behavior could be observed on solar cell with Epoxy/Backsheet/EVA/Cell stacking sequence, in contrast, no obvious PID characteristic change was noticed for specimen with Epoxy/Glass/EVA/Cell structure. Furthermore, deeper analysis on the different operating temperatures and types of backsheet effect on the environmental-induced PID behavior of PV backsheets were also carried out based on the previous mentioned-notices. Results of the former experiment showed that the impurities in the epoxy could penetrate into the solar cell through the backsheet material rather than the front glass and experimental results of the later showed that thermal stability of PV backsheet at operating temperatures of testing system could dominate the degree of severity on PID behavior. Moreover, the experimental design also provided a new environmental impurities induced PID verification method.

description: The bottleneck of obtaining high efficiency CIGS thin film solar cells is that their bandgap must be smaller than 1.2 eV. Wider bandgap thin film CIGS solar cells with high Ga content are of great interests. However, the leading challenge is that the Ga will accumulate at the back side of CIGS absorber. In this study, the influences of the Ga content on the performance and morphology of the CIGS solar cells are investigated. In addition, the current collection properties of the CIGS solar cells is studied by SEM-EBIC. The performances and the current collection length of the high-Ga content (GGI=42%) CIGS solar cells are improved by the modified three stage process. The open circuit voltage (VOC) of was improved by 30 mV by the modified three stage process with efficiency improved from 16.5% to 19.2% without antireflection coatings. The efficiency of the high-Ga CIGS solar cells would exceed 20% if AR coating was deposited on top or the solar cells.

description: Hydrogenated amorphous Si(a-Si:H) Quintuple-junction solar cells which consist of a-SiOx:H/aSiOx:H/a-Si:H/a-SiOx:H/a-SiOx:H were fabricated by plasma CVD method. The total thickness was 0.6-0.8 m. Irradiation intensity (Pin) dependence of the open circuit voltage (Voc) of quintuple-junction solar cells was measured. The decreasing amount Voc (1/10) of the open-circuit voltage when the irradiation intensity became 1/10 was 62mV/cell. Voc drops rapidly from around the irradiation intensity of 1mW/cm2 (approximately 1,000 lux). This large Voc reduction is due to leakage current. Then, we discussed the origin of the leakage current, and finally by improving the leakage current, a very high open-circuit voltage Voc of 3.5 V was demonstrated under LED light illumination. Furthermore, we theoretically analyzed Voc as a function of the irradiation intensity, including effects of the leakage current and the film quality of i-a-Si(O):H. It was found from the simulation results that it is necessary to increase the shunt resistance Rsh and to lower the defect density of i-a-Si(O):H in order to obtain a sufficient Voc-Pin characteristics for IoT devices application under low illuminance.

description: Optical emission spectroscopy (OES) was performed during the deposition of SiNx layers in an industrial-scale plasma-enhanced chemical vapor deposition (PECVD) tool. Emission spectra peaks were correlated to deposition properties: deposition rate, refractive index, and bond densities. A statistical model was built to predict layer properties for silicon nitride deposition using different process parameters. This model was used to build a multivariate linear correlation between process parameters and film properties. The accuracy of the results showed a deviation of less than 10.3% for layer thickness, 1.7% for refractive index and 35.8% for bond densities. Based on these results, we propose OES as a powerful method that can be used not only to increase the process control but also for statistical modelling. Moreover, the inversion of the multivariate correlation allows calculation of the multiple sets of process parameters for depositing silicon nitride layers with given properties.

description: We give a direct tensor decomposition for any density matrix into Hermitian operators. Based upon the decomposition we study when the mixed states are separable and generalize the separability indicators to multi-partite states and show that a density operator is separable if and only if the separable indicator is non-negative. We then derive two bounds for the separable indicator in terms of the spectrum of the factor operators in the tensor summands.

Measuring the impact of regulation in a dynamic context : an application to Bell Canada
Creators: name: Patry, Michel
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis, a model of producer behavior for a regulated utility that fully takes into account the dynamic nature of the capital accumulation process of the firm is developed and empirically implemented using recent data on Bell Canada. On the basis of this model of producer behavior, loss formulae that approximate the value of foregone output due to imperfect regulation in a dynamic context are derived and estimates of the deadweight loss in the case of Bell are provided. The estimation results indicate the importance of dynamic elements, such as expectations and adjustment costs of investment, in modeling the behavior of Bell. They also suggest that rate of return regulation may have affected the investment decisions of the utility.

description: A recent study [D. Helbing, A. Johansson and H. Z. Al-Abideen, {\it Phys. Rev. E} 75, 046109 (2007)] has revealed a "turbulent" state of pedestrian flows, which is characterized by sudden displacements and causes the falling and trampling of people. However, turbulent crowd motion is not reproduced well by current many-particle models due to their insufficient representation of the local interactions in areas of extreme densities. In this contribution, we extend the repulsive force term of the social force model to reproduce crowd turbulence. We perform numerical simulations of pedestrians moving through a bottleneck area with this new model. The transitions from laminar to stop-and-go and turbulent flows are observed. The empirical features characterizing crowd turbulence, such as the structure function and the probability density function of velocity increments are reproduced well, i.e. they are well compatible with an analysis of video data during the annual Muslim pilgrimage.

description: Effect of laser energy were studied to improve the electrical performance and output power of selective emitter PERC silicon solar cells. Laser frequency, scanning speed, pulse power, and spot size were optimized to obtain different laser energy and overlap between each spots. In this paper, laser energy was varied to provide qualitative analysis of the damage on laser doped regions. SEM images show spheres formed near the tip of each pyramid after laser doping, and these spheres became smaller and less frequent with reducing laser energy. Moreover, key parameters such as overlap and spot size were also investigated. When decreasing the overlap between each spot from 8% to 5%, the damaged region decreased, and the Voc and Jsc reached 679.03mV and 39.4mA/cm2, and efficiency was improved by 0.12%. When the spot size decreased from 120um to 100um, Voc was 1.15mV higher and Jsc kept the same but the final efficiency had no improvement which can been explained by the increase in series resistance of about 0.12 mΩ. Further optimisation to reduce the laser damage by reducing overlap and adopting narrower spot size is expected to further improve the cell efficiency.

description: A further step has been carried out in order to produce an ink formulation for screen printing purposes capable of providing contacts compatible with perovskite substrates. This has been achieved by developing a mixed binder, comprised by epoxy resin and collodion that produces perovskite-friendly contacts that present an average volumen resistance of 2.282 Ω • cm, with a standard deviation of 1,621 Ω • cm. Although these results represent a slight improvement over those obtained previously, these have not made a sufficiently representative difference to continue along this line of research without considering the implementation of significant alternatives. In this sense, the paper concludes with the logic behind intruducing carbon black in our ink formulations.

description: In this study, the electrical and optical characteristics of the crystalline silicon solar cells coated a luminescent down-shifting (LDS) layer comprising Eu-doped phosphor particles with silver nanoparticles (Ag NPs) to enhance conversion efficiency due to fluorescence enhancing from plasmonics excitation are demonstrated. The enhanced fluorescence of Eu-doped phosphor particles incorporated with and without Ag NPs was examined by photoluminescence measurements using a 405 nm optical pump source at room temperature. The LDS characteristics of the Eu-doped phosphors and the Eu-doped phosphors combining with Ag NPs were revealed by the measurements of absorbance and optical reflectance. The photovoltaic performances of the silicon solar cells coated with a layer of LDS of Eu-doped phosphor particles comprising with and without Ag NPs are also confirmed by photovoltaic current density-voltage measurement under one sun AM 1.5G illumination. In this work, the efficiency improvement of 17.83% for the cell coated with a LDS layer comprising Ag NPs was higher than that of 15.94% for the cell coated with a LDS layer without Ag NPs, compared to the reference silicon solar cells.

It provides a quick proof of meromorphy of Feynman amplitudes in parameters such as the dimension of space-time. In particular it paves the road for the dimensional renormalization of these theories. This complete Mellin representation also allows the study of asymptotic behavior under rescaling of arbitrary subsets of external invariants of any Feynman amplitude.

We calculate the precision with which the strength of the nonlinearity can be estimated and show that it scales as $1/n^{3/2}$, where $n$ is the mean phonon number of the initial state. This result holds even in the presence of dissipation, but assumes the ability to make measurements of the quadrature components of the nanoresonators.

description: The present study analyzes the extent of output commercialization among poor and non-poor lychee farmers in Luc Ngan District, BacGiang Province, Vietnam. The two groups of farmers are compared in terms of socio-economic characteristics and degree of participation in the lychee market. OLS regression analysis is used to analyze the factors affecting the degree of output commercialization. Results show that both poor and nonpoor farmers participated actively in the output market, although commercialization index was higher for the non-poor (89.2%) than the poor farmers (86.70%). Age, education, experience of household head, farm size, market information access, crop yield and price of lychee have positive influence on output commercialization. Household size and distance to output market have negative effect. The study recommends that poor farmers should be assisted in terms of enhanced bargaining power through collective marketing and exploration of new markets, support for processing and value-addition, and improvement of Luc Ngan’s market information and extension system.

description: While it is known that the QCD vacuum in a magnetic background exhibits both diamagnetic and paramagnetic characteristics in the low-energy domain, a systematic investigation of the corresponding phases emerging in the pion-dominated regime is still lacking. Here, within two-flavor chiral perturbation theory, taking into account the pion-pion interaction, we analyze the subtle interplay between zero- and finite-temperature portions in the magnetization and magnetic susceptibility. The dependence of the magnetic susceptibility on temperature and magnetic field strength in the paramagnetic and diamagnetic phase is non-monotonic. Our low-energy analysis complements lattice QCD that is currently operating at higher temperatures and stronger magnetic fields.

description: We present a catalogue of 18 new Galactic supernova remnants (SNRs) uncovered in the optical regime as filamentary emissions and extended nebulosities on images of the Anglo Australian Observatory/United Kingdom Schmidt Telescope (AAO/UKST) HAlpha survey of the southern Galactic plane. Our follow-up spectral observations confirmed classical optical SNR emission lines for these 18 structures via detection of very strong [SII] at 6717 and 6731A relative to HAlpha ([SII]/HAlpha> 0.5). Morphologically, 10 of these remnants have coherent, extended arc or shell structures, while the remaining objects are more irregular in form but clearly filamentary in nature, typical of optically detected SNRs. In 11 cases there was a clear if not complete match between the optical and radio structures with H filamentary structures registered inside and along the presumed radio borders. Additionally, ROSAT X-ray sources were detected inside the optical/radio borders of 11 of these new remnants and 3 may have an associated pulsar. The multi-wavelength imaging data and spectroscopy together present strong evidence to confirm identification of 18 new, mostly senile Galactic SNRs. This includes G288.7-6.3, G315.1+2.7 and G332.5-5.6, identified only as possible remnants from preliminary radio observations. We also confirm existence of radio quiet but optically active supernova remnants.

description: A new kind of Q-balls is found: Q-balls in a non-linear sigma model. Their main properties are presented together with those of their self-gravitating generalization, sigma model Q-stars. A simple special limit of solutions which are bound by gravity alone (``sigma stars'') is also discussed briefly. The analysis is based on calculating the mass, global U(1) charge and binding energy for families of solutions parameterized by the central value of the scalar field. Two kinds (differing by the potential term) of the new sigma model Q-balls and Q-stars are analyzed. They are found to share some characteristics while differing in other respects like their properties for weak central scalar fields which depend strongly on the form of the potential term. They are also compared with their ``ordinary'' counterparts and although similar in some respects, significant differences are found like the existence of an upper bound on the central scalar field. The sigma model Q-stars also contain non-solitonic solutions whose relation with sigma star solutions is discussed.

description: We have measured the absolute proper motions of globular clusters NGC 2808, 3201, 4372, 4833, 5927 and 5986. The proper motions are on the Hipparcos system and they are the first determinations ever made for these low Galactic latitude clusters. The proper motion uncertainties range from 0.3 to 0.5 mas/yr. The inferred orbits indicate that 1) the single metal rich cluster in our sample, NGC 5927, dynamically belongs to the thick disk, 2) the remaining metal poor clusters have rather low-energy orbits of high eccentricity; among these, there appear to be two "pairs" of dynamically associated clusters, 3) the most energetic cluster in our sample, NGC 3201 is on a highly retrograde orbit -- which had already been surmised from its radial velocity alone -- with an apocentric distance of 22 kpc, and 4) none of the metal poor clusters appear to be associated with the recently detected SDSS streams, or with the Monoceros structure. These are the first results of the Southern Proper-Motion Program (SPM) where the second-epoch observations are taken with the CCD camera system recently installed on the double astrograph at El Leoncito, Argentina.

description: This is initial study of a gene signatures responsible for adapting microscopic life to the life in extreme Earth environments. We present a results on ID of the clusters of COGs common to several hyperthermophiles and exclusion of those common to a mesophile: E.coli.K12, will yield a group of proteins possibly involved in adaptation to life under extreme T. Methanogens stand out as the only group of organisms that have species capable of growth at 0C (M.frigidum and M.burtonii) and 110C (M.kandleri). Not all the components of heat adaptation can be attributed to novel genes, the chaperones known as heat shock proteins stabilize the enzymes under elevated temperature. Highly conserved chaperons found in bacteria and eukaryots are not present in hyperthermophilic Archea, rather, they have a unique chaperone TF55. Our aim is to use software which we specifically developed for extremophile genome comparative analyses in order to search for additional novel genes involved in hyperthermophile adaptation. The following hyperthermophile genomes incorporated in our software were used for these studies: M.jannaschii, M.kandleri, A.fulgidus and 3 species of Pyrococcus. Common genes were annotated and grouped according to their roles in cellular processes when information was available and proteins not previously implicated in the heat-adaptation of hyperthermophiles were identified. Additional experimental data is needed in order to learn more about these proteins. To address a non-gene based components of thermal adaptation, all sequenced extremophiles were analysed for their GC contents and aminoacid hydrophobicity. We develop a prediction model for optimal growth temperature.

description: The selection of schools follows a stratified probability proportional to size (PPS) sampling method. The stratification considers two dimensions at the national level: municipality status (village, town, statutory city) and socio-economic status (SES), which depends on employment rates and the proportion of university-educated residents. These indicators convert into z-scores, and municipalities fall into low (below median) and high (above median) SES groups, resulting in six stratification categories. The target distribution of selected schools reflects the proportion of student capacity within each category at the national level. Within each stratum, schools located within a 45-minute driving distance from Olomouc are randomly selected using PPS, giving larger schools a higher probability of selection.

description: The mapping of the Nonlinear Schroedinger Equation with a random potential on the Fokker-Planck equation is used to calculate the localization length of its stationary states. The asymptotic growth rates of the moments of the wave function and its derivative for the linear Schroedinger Equation in a random potential are computed analytically and resummation is used to obtain the corresponding growth rate for the nonlinear Schroedinger equation and the localization length of the stationary states.

description: Excerpts from the report: The Malagasy Republic is a land of substantial agricultural potential. Rice is the main crop and sizable gains in production are likely with the use of improved technology, particularly improved irrigation. The country's resources favor a large cattle population and prospects for increased commercial utilization of cattle are bright. Agriculture is the principal occupation in the Malagasy Republic. Over 90 percent of the population is engaged in a largely traditional agriculture which accounts for about 54 percent of gross domestic product (GDP). Agricultural products, primarily coffee, rice, vanilla, spices, and sugar, make up 80 to 90 percent of the value of the country's exports.

description: A systematic work has been performed in order to evaluate the effects of the moist on the deposition stages of Methylammonium lead iodide (CH3NH3PbI3 or MAPbI3) layers in ambient conditions, at a relative humidity (RH) range between 30 and up to 80%, considering also two types of solvents during the solution preparation ones: dimethylformamide (DMF) and a mixture of dimethylformamide and dimethylsulfoxide (DMSO) with a 9:1 volume ratio. After the deposition steps, uniform and smooth mirror-like perovskite layers were obtained. Subsequently, their optical properties and chemical composition were analyzed using spectral ellipsometry and X-ray crystallography techniques. The obtained results indicated that the use the two aforementioned solvents led to almost negligible differences in the deposited layers, with slight advantage in the use of DMF over DMF:DMSO 9:1 volume rate at a HR between 30 and 55%, and in the use of DMF:DMSO 9:1 volume rate over DMF at a HR higher than 60%.

description: In this paper we study cosmological application of interacting holographic dark energy density in the scalar-Gauss-Bonnet framework. We employ the interacting holographic model of dark energy to obtain the equation of state for the interacting holographic energy density in spatially flat universe. Our calculation show, taking $Ω_Λ=0.73$ for the present time, it is possible to have $w_{\rm Λ}^{eff}$ crossing -1. This implies that one can generate phantom-like equation of state from the interacting holographic dark energy model in flat universe in the scalar-Gauss-Bonnet cosmology framework. Then we reconstruct the potential of the scalar field.

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 977-982
description: Power output results of module measurements performed in independent laboratories often appear lower than those indicated on the label. The reason for this effect is that several factors that may affect a PV module’s power output, are not taken into account. PV modules made of crystalline silicon solar cells suffer an initial slight loss in peak power, an effect known as “light induced power stabilization” [1,2]. Many module producers know this effect and have this light induced degradation (LID) included in their product guarantee. Before starting the IEC reliability tests, PV modules need to show a stable output. Which is why they must be exposed to sunlight or a solar simulator at over 20kWh/m2. This power stabilization test is also compulsory according to the IEC 61215 standard on certification of photovoltaic modules [3]. When different combinations of module materials are tested for durability in, for instance, damp heat (DH) and thermal cycle (TC) testing, stable solar cells are needed as a reference to distinguish between the various effects of the materials. In the performed experiments, durability testing results with and without light soaking (40kWh) were compared.
Radiative heavy quark energy loss in a dynamical QCD medium

description: The computation of radiative energy loss in a dynamically screened QCD medium is a key ingredient for obtaining reliable predictions for jet quenching in ultra-relativistic heavy ion collisions. We calculate, to first order in the opacity, the energy loss suffered by a heavy quark traveling through an infinite and time-independent QCD medium and show that the result for a dynamical medium is almost twice that obtained previously for a medium consisting of randomly distributed static scattering centers. A quantitative description of jet suppression in RHIC and LHC experiments thus must correctly account for the dynamics of the medium's constituents.

description: Small and medium enterprises play a vital role in the agro-industrial development and growth of the Malaysian economy. This paper identifies development issues, major challenges and prospects faced by the Malaysian SMEs entrepreneurs and managers and discusses crucial SMEs development interventions as well as some important lessons learned from their experiences to serve as “guides” to the Philippine government and the local SMEs. Research findings reveal that development issues and challenges include limited adoption of technology, lack of human resources, competition from multinational companies and globalization. In addition, key factors of success were identified: ability to respond quickly to market signals, systematic production and operations management and personal networking. The Malaysian SMEs benefited from the economy’s resilience and competitiveness which are attributed to the continuing fiscal reforms, diversification of the economy and up skilling of capabilities and expertise among others. The country focuses on SMEs strategies such as product innovations in food and beverage manufacturing industry and technology adoption, human capital development, access to financing, market access and infrastructures.
