Comparison of LSSVR, M5RT, NF-GP, and NF-SC Models for Predictions of Hourly Wind Speed and Wind Power Based on Cross-Validation

Accurate predictions of wind speed and wind energy are essential in renewable energy planning and management. This study was carried out to test the accuracy of two different neuro fuzzy techniques (neuro fuzzy system with grid partition (NF-GP) and neuro fuzzy system with substractive clustering (NF-SC)), and two heuristic regression methods (least square support vector regression (LSSVR) and M5 regression tree (M5RT)) in the prediction of hourly wind speed and wind power using a cross-validation method. Fourfold cross-validation was employed by dividing the data into four equal subsets. LSSVR’s performance was superior to that of the M5RT, NF-SC, and NF-GP models for all datasets in wind speed prediction. The overall average root-mean-square errors (RMSE) of the M5RT, NF-GP, and NF-SC models decreased by 11.71%, 1.68%, and 2.94%, respectively, using the LSSVR model. The applicability of the four different models was also investigated in the prediction of one-hour-ahead wind power. The results showed that NF-GP’s performance was superior to that of LSSVR, NF-SC, and M5RT. The overall average RMSEs of LSSVR, NF-SC, and M5RT decreased by 5.52%, 1.30%, and 15.6%, respectively, using NF-GP.
Information Technology Adoption Efforts in Improving The Performance of Indonesia SMEs

Information Technology (IT) adoption efforts and implementation of new technology in the Small Medium Enterprises (SMEs) sector with a good level of success is very important in the performance of SMEs business. This study aims to analyze the causal relationship between the success of ERP system with SMEs performance and payment gateway by adopting it as a moderation variable, then consider employee size of SMEs as a control variable. The owner or manager of SMEs from 63 SMEs in Indonesia completed the questionnaire analyzed through empirical analysis by using Smart PLS. In investigating the analysis of control variable will empirically using the Random Effect Model to analyze the effect of employee size on SMEs performance. The results of this study indicate that the adoption of IT through the success of the ERP system has a significant impact on SMEs performance, but the implementation of payment gateways has failed to moderate the performance of SMEs, and then the employees size of SMEs (as a variable control) has an impact on Indonesian SMEs performance. Furthermore, the research contribution shows that IT adoption efforts in ERP system success and Payment Gateway implementation as new technology will have the impact on improving the SMEs performance.
Adoption of Information Technology in Public Administration: a Focus on the Organizational Factors of a Brazilian Federal University

Objective: This study aims to analyze the influence of organizational factors in the adoption of the information system at UFCG. Methodology: This is quantitative research in which a survey at the Federal University of Campina Grande (UFCG) is carried out applying Structural Equation Modelling via R software. Results: The results confirmed the positive influence of training and top-management support on the perception of ease; of top-management support on the perception of usefulness; and the perception of usefulness on the perceived benefits of the Electronic Information System (EIS). Theoretical Contri-butions: This research advances in studies on information technology (IT) and its implication in Public Administration, and, as it has multidisciplinary academic support, presents contributions to practice and theory in a related way. A relevant theoretical contribution is that the results of measurements for perceived usefulness (PU) and benefits reinforce the need for a better understanding towards concepts and variables of both constructs. Such a situation open ups new opportunities for theory to understand such constructs in a mandatory context of IT. Practical contributions: For professionals, it provides subsidies for institutions adopting information systems to promote a more favorable environment for their acceptance. Once the relevance of training programs, coupled with the support of top management, has the potential to increase the perception of the quality of the system by users, and thus, greater assimilation of the benefits linked to this system, impacting its acceptance.
Light Asymmetric Dark Matter on the Lattice: SU(2) Technicolor with Two Fundamental Flavors

The SU(2) gauge theory with two massless Dirac flavors constitutes the building block of several models of Technicolor. Furthermore it has also been used as a template for the construction of a natural light asymmetric, or mixed type, dark matter candidate. We use explicit lattice simulations to confirm the pattern of chiral symmetry breaking by determining the Goldstone spectrum and therefore show that the dark matter candidate can, de facto, be constituted by a complex Goldstone boson. We also determine the phenomenologically relevant spin one and spin zero isovector spectrum and demonstrate that it is well separated from the Goldstone spectrum.
EURASIAN JOURNAL OF ECONOMICS AND FINANCE

If it studies the relationship between crude oil price and U.S. dollar, classical literature finds a positive sign for the correlation of these two variables, i.e. the oil price and the dollar grow up together or they fall together. Instead, researches which use the data of more recent years show a negative link, so that if one variable is rising, the second one is decreasing and vice versa. Besides, there are two possible directions of causality: the economic theory explains the influence of oil price towards U.S. dollar; while the financial perspective is coherent with the opposite way. This second thesis is confirmed by the empirical evidence. In this framework, the futures and other financial derivatives have changed the picture, modifying how crude oil is priced and valued by the market. In this paper, we review the literature about the above relationship, inspecting whether or not the empirical results validate the theory, under the financial point-of view, i.e. the second interpretation.
Fiscal Rules Cause Lower Debt: Evidence from Switzerland's Federal Debt Containment Rule

This paper studies the effect of the Swiss federal debt containment rule on public debt. Using the synthetic control method, we provide evidence that the introduction of the federal rule in 2003 has reduced public debt ratio in Switzerland by 2.5 percentage points on average until 2010. By exploiting possible mechanisms, we find no evidence that the reduction in debt ratio was driven by a debt relocation to sub‐government levels or cutbacks in investment expenditure. On one hand, we argue that the positive impact of the fiscal rule is based on its design features, namely its precise but cyclically adjusted target, the comprehensive scope to prevent budget loopholes, and the strict sanction mechanism. On the other hand, we also discuss the generalizability of our findings to other countries and contend that its direct democratic authorization has contributed to its political enforcement and viability.
A Survey of Technology Readiness Level Users

The Technology Readiness Level (TRL) method, used to assess the maturity of a technology, has been applied in different industries for over 40 years. TRLs assist engineers in managing risks, communicating development progress and specifying deliverables. As TRLs have been adopted in more industries, the original scope of TRL application has expanded and challenges in use have emerged. Little is known about the TRL user community and its opinions of the method, or of the method's practical challenges. A global industry survey, conducted with professional TRL users, investigated the relative importance of 15 previously identified challenges of TRL use. We find that the top four most critical TRL challenges as identified by our respondents are system‐related; they include the topics of integration, interfaces, system modifications, and overall system maturity. The results reveal a need for an extension of the TRL method from a component‐readiness‐context to a system‐readiness‐context.
Assessment of community knowledge, attitude and practice on common zoonotic diseases in Jinka town, Southern Ethiopia

A cross-sectional study was conducted from November 2018 to May 2019 in and around Jinka town, to assess the community’s knowledge, attitude, and practice on common zoonotic disease. A total of 330 randomly selected participants had voluntarily filled the semi-structured questionnaire. Accordingly, age, religion, education, occupation and marital status of the respondents were significantly associated with their knowledge on the zoonotic disease in which respondents with the age group greater than 15 years, orthodox and catholic religious affiliations, health professionals and married ones had greater knowledge towards zoonotic disease (P<0.05). The effect of educational background of the respondents on their at- titude towards zoonotic disease treatment, prevention, control, and advantages of vaccine provision was found to be statistically significant. Among those who have a positive perception of zoonotic treatment, about 35.8% of respondents were having college and university education while 49.2% of those who didn’t have a positive perception of the zoonotic disease treatment were illiterate. The educational level of the respondents was significantly associated with their practices towards zoonotic diseases (P<0.05). Respondents with lower educational levels had higher contact with animals, consume more raw meat, didn’t take pre-exposure vaccination, and didn’t take immediate action for infected animals by zoonotic diseases. In conclusion, community education and awareness programs are required for further improvement of the knowledge, attitude, and practice of the community on zoonotic diseases. Besides, the integration of one health approach towards the control of zoonotic diseases is important.
Are covered bonds a substitute for mortgage-backed securities?

Given the problems in the mortgage-backed securities (MBS) market during the financial crisis, some suggest that covered bonds (CB) might be a substitute for MBS. This could lead to a number of policy alternatives in countries where regulation and business have been mainly leaning to one of these types of securities. Examining the use of CB and MBS in the U.S. and Europe, we find that the two often seem to be used for different purposes. Banks are more likely to use CB when they have liquidity needs while MBS are associated with risk management and agency problems. Introducing MBS to markets where only CB are common or CB to markets where only MBS are common could have large effects.
Laminar Flame Speed Measurements of Synthetic Gas Blends With Hydrocarbon Impurities

New Laminar Flame Speed measurements have been taken for a wide range of syngas mixtures containing hydrocarbon impurities. These experiments began with two baseline syngas mixtures. The first of these baseline mixtures was a bio-syngas with a 50/50 H2/CO split, and the second baseline mixture was a coal syngas with a 40/60 H2/CO split. Experiments were conducted over a range of equivalence ratios from ϕ = 0.5 to 3 at initial conditions of 1 atm and 300 K. Upon completion of the baseline experiments, two different hydrocarbons were added to the fuel mixtures at levels ranging from 0.8 to 15% by volume, keeping the H2/CO ratio locked for the bio-syngas and coal syngas mixtures. The addition of these light hydrocarbons, namely CH4 and C2H6, had been shown in recent calculations by the authors to have significant impacts on the laminar flame speed, and the present experiments validated the suspected trends. For example, a 7% addition of methane to the coal-syngas blend decreased the peak flame speed by about 25% and shifted it from ϕ = 2.2 to a leaner value near ϕ = 1.5. Also, the addition of ethane at 1.7% reduced the mixture flame speed more than a similar addition of methane (1.6%). In general, the authors’ chemical kinetic model over predicted the laminar flame speed by about 10–20% for the mixtures containing the hydrocarbons. The decrease in laminar flame speed with the addition of the hydrocarbons can be explained by the increased importance of the inhibiting reaction CH3 + H (+M) ↔ CH4 (+M), which also explains the enhanced effect of C2H6 compared to CH4, where the former produces more CH3 radicals, particularly at fuel rich conditions.Copyright © 2015 by ASME
Capacitance characterization of AlN/GaN double‐barrier resonant tunnelling diodes

We report on the electrical characterization of AlN/GaN/AlN double-barrier resonant tunnelling diodes (RTDs) using steady-state current-voltage and capacitance-voltage (C-V) characteristics in a wide frequency range with 2 kHz steps. The C-V characteristics of a double-barrier RTD show different behaviour under forward and reverse polarities and a strong dependence on frequency. The monotonous growth of capacitance at forward bias was registered, while a more complicated dependence was observed at reverse voltages. In order to analyse this dependence, a self-consistent calculation of the potential profile of the structure was performed taking into account polarization effects at the AlN/GaN interfaces. The peculiarities are analysed in the model of possible charge trapping at the interface states. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
Personal Financial Literacy among University Students studying Engineering

Nowadays financial literacy is essential as in a society much of the financial responsibility has shifted from governments to the individual. The findings of earlier studies show that university students are not knowledgeable about personal finance and their financial skills needs improvement. This study analyzed the survey results of 536 university students to assess the financial literacy, the impact of educational and demo-graphical characteristics to the participants' financial literacy, and the students' financial opinions and choices. Results of regression analyze showed that statistically significant impact to the financial literacy had factors: academic discipline, level of education, gender, nationality, age and the choices to have a current account, a debit card, and investment services. Students studied in the Faculty of Civil Engineering compared to others, had higher knowledge in finance, especially female students. These results of study give the direction for future research and enable to enhance financial education.
COMMUNITY SUPPORTED AGRICULTURE: FILLING A NICHE MARKET

In less than a decade, the number of Community Supported Agriculture (CSA) projects has grown to more than 400. Our research suggests that CSA shareholders' social objectives dominate their decision to join. Standard economic objectives and "club-related" objectives contribute to the decision, but are clearly secondary. Our research also suggests the CSA movement will continue to grow. Its emphasis on social objectives, its inability to supply food year around, and the ongoing development of size-neutral organic technologies, however, will probably keep it from becoming a major market channel in the next century.
Morphological and Numerical Characteristics of the Southern Chinese dentitions. Part I: Anomalies in the Permanent Dentition

Aim: To investigate the prevalence of eight morphological and numerical anomalies in the southern Chinese permanent dentition and to compare these with studies from different populations. Materials and Methods: The material used in the study consisted of study models and panoramic radiographs collected from 725 randomly selected 12-year-old children (358 males and 367 females). The anomalies were assessed using diagnostic criteria that have been most often cited in the published literature. Results: Of the eight dental anomalies studied, the prevalence of hyperdontia (2.6%) was higher than reported for Caucasians, and double tooth (0.8%) and dens evaginatus (4.7%) were the highest amongst all of the populations. Although the prevalence of hypodontia (7.3%) is comparable to that of other populations, mandibular incisors were the most frequently missing teeth in southern Chinese (5.6%) and this finding contradicted those from studies of other ethnic groups. Conclusion: Higher prevalences of double tooth, dens evaginatus and missing mandibular incisors can be considered to be characteristics of the southern Chinese permanent dentition.
Functional groups of wild bees respond differently to faba bean
 Vicia faba
 L. cultivation at landscape scale

1. Concerns about insect declines are growing and the provisioning of ecosystem services like pollination may be threatened. To safeguard biodiversity, greening measures were introduced within the reform of the EU's Common Agricultural Policy. One measure commonly applied by farmers is the cultivation of nitrogen fixing crops. Although underlying studies are largely missing, this measure is criticized as providing no significant biodiversity benefit. 2. Using a landscape-scale approach, we selected 30 paired study landscapes (1 km × 1 km) in Germany, that is, 15 study landscapes with faba bean (FB) fields (Vicia faba L .) a nd 15 w ithout a ny g rain l egumes. F lower-visiting w ild b ees were recorded with transect walks at the field margins of different crops using a stratified sampling approach. We analysed the effect of FB cultivation and landscape composition on the abundance and species richness of wild bees as well as on the functional composition of the bee communities. 3. Bumblebee densities (Bombus spp. Latreille) were more than twice as high in FB compared to control landscapes after the flowering of the beans. Non-Bombus wild bee densities, however, were not affected by FB cultivation, but were enhanced by increasing amounts of semi-natural habitats (SNH). 4. After the beans' blooming had ceased, FB landscapes had a higher proportion of wild bees collecting pollen from Fabaceae than control landscapes. The communityweighted means for bee size, measured as intertegular distance, were not affected by FB cultivation, but we found smaller species and species with shorter tongues with an increasing percentage of SNH. 5. Synthesis and applications. The cultivation of faba bean Vicia faba L . s trongly increased bumblebee densities throughout the season. This indicates that also on-field greening measures can support biodiversity. Nevertheless, since only functional groups adapted to faba bean benefit, measures to promote seminatural habitats in agricultural landscapes need to be implemented. We conclude that the combination of on- and off-field measures is essential to maintain farmland biodiversity and the Common Agricultural Policy should furthermore promote both.
Exploring the effects of visual and literary arts interventions on psychosocial well-being of diverse older adults: a mixed methods pilot study

ABSTRACT Background Engagement in the arts may have health benefits for older adults. Most research has focused on music and dance; less is known about the benefits of other arts interventions. The purpose of this study was to examine the effects of visual (ceramics and collage) and literary arts (storytelling and writing) on well-being. Methods We used mixed methods to examine the effects of a 12-week visual or literary arts intervention on well-being. Adults age 55 and over from four housing sites were assigned to start an intervention immediately (intervention) or wait 12 weeks (controls). The study included pre/post-test measures of well-being and focus groups about perceived benefits. Results Compared to controls, participants in the ceramics intervention had significant improvements in interest in life and mastery, while no changes were observed after the storytelling intervention. Seven psychosocial benefits were identified . Conclusions Participation in visual and literary arts for older adults was associated with well-being media.
Eliciting beliefs in continuous-choice games: a double auction experiment

This paper proposes a methodology to implement probabilistic belief elicitation in continuous-choice games. Representing subjective probabilistic beliefs about a continuous variable as a continuous subjective probability distribution, the methodology involves eliciting partial information about the subjective distribution and fitting a parametric distribution on the elicited data. As an illustration, the methodology is applied to a double auction experiment, where traders’ beliefs about the bidding choices of other market participants are elicited. Elicited subjective beliefs are found to differ from proxies such as Bayesian Nash equilibrium beliefs and empirical beliefs, both in terms of the forecasts of other traders’ bidding choices and in terms of the best-response bidding choices prescribed by beliefs. Elicited subjective beliefs help explain observed bidding choices better than BNE beliefs and empirical beliefs. By extending probabilistic belief elicitation beyond discrete-choice games to continuous-choice games, the proposed methodology enables to investigate the role of beliefs in a wider range of applications.
Characterization of a 52 K protein of murine cytomegalovirus and its immunological cross-reactivity with the DNA-binding protein ICP 36 of human cytomegalovirus

We have developed a hybridoma, designated 25G11, which produced a monoclonal antibody (MAb) reactive with a 52K protein of murine cytomegalovirus (MCMV). This MAb, 2 5 G l l , was reactive with a protein band of 52K in MCMV-infected cell lysates and with a protein of 49K in human CMV (HCMV)infected cell lysates as detected by immunoblot analysis. With purified MCMV virions, 25G11 gave a faintly immunoreactive band of 52K. However, no immunoreactive protein band was detected with purified HCMV virions, nor with purified HCMV or MCMV envelope preparations. By immunocytochemistry, 25G11 detected-viral antigen primarily in the nucleus of HCMVor MCMV-infected cells. The antibody 25G11 was used to screen a 2gtl 1 library of HCMV DNA fragments. One of the isolated clones (232323B) was employed for gene mapping on the HCMV genome, which suggested that the immunoreactive HCMV protein was the DNA-binding protein (ICP36). Analysis of the recombinant fusion protein with antibody 25G11 and with an MAb (CH16) specific for a n HCMV DNA-binding protein confirmed the identity of the cross-reacting protein as ICP36. Furthermore, we found that whereas the epitope recognized by 2 5 G l l was conserved between HCMV and MCMV proteins, the epitope recognized by CH 16 was unique "to HCMV and thus represents a variable region in the protein.
Cognitive Ageing in Developing Societies: An Overview and a Cross-sectional Study on Young, Middle-aged and Older Adults in the Indian Context

Cognitive ageing in developing societies is marked with psychosocial issues such as education, occupation, lifestyle, social support, social interaction and exclusion that may affect cognitive–affective–behavioural changes with ageing. We also present a study based on cognitive profiling of young (N = 79), middle-aged (N = 54) and older adults (N = 43) in India, which examined learning and memory for verbal and visuospatial information, overall cognitive functions, subjective complaints about cognitive difficulties, neuropsychiatric problems, anxiety and emotion regulation. The study shows cognitive changes compared to young and comparable rate of learning and retrieval among middle-aged and older adults for verbal and visuospatial material, correlated with general cognitive ability. The subjective complaints were not correlated with the objective measures of cognitive functions, highlighting the importance of both to show early cognitive changes. The relationship between cognitive functions and emotion regulation or behavioural/emotional changes was observed for young and middle-aged adults but not for older adults. Findings are discussed in the context of the lifespan perspective of cognitive ageing, cognitive reserve, psychosocial environment and social–emotional selectivity theory.
