On‐farm Performance and Farmers’ Perceptions of
 DroughtTEGO
 ‐Climate‐Smart Maize Hybrids in Kenya

Agronomy Journa l • Volume 111, I s sue 6 • 2019 AbstrAct Maize (Zea mays L.) productivity in the sub-Saharan Africa is constrained by biotic and abiotic stresses that reduce yield. In the region, one of the most serious abiotic factor is frequent intermittent droughts, which has been attributed to climate change. The purpose of this paper was to use on-farm demonstration studies and farmer field days to demonstrate new drought mitigation technology and provide information on how small farmers can reduce yield losses. A total of 4814 demonstration plots of 39 DroughtTEGO maize hybrids and 19 commercial check hybrids were established in 17 counties across the low-to-midaltitude maize-growing agroecologies of Kenya between 2015 and 2017. A total of 246 field-day workshops were conducted. Combined analyses across years and locations showed that top five DroughtTEGO hybrids increased maize yields 33 to 54% (5.5–6.3 Mg ha–1) relative to conventional hybrids. The highest yield advantage of DroughtTEGO hybrids over commercial checks was observed in the drier lower eastern region in Kenya. Farmers particularly women, preferred the DroughtTEGO hybrids because of the stay-green character, whiteness of flour (milling quality), root lodging resistance, drought-tolerance and shelling percentage. Results from this study suggested that smallholder farmers can reduce the impact of drought by seeding drought-tolerant maize hybrids.
Academicians Viewpoint on Port Managers Prior Competencies in terms of Environmental Sustainability Performance of Container Port Enterprises in Turkey

Ports regard sustainability as of great importance in their efforts to sustain their corporate feature aiming to use resources effectively and comply with the environment and the society in which they are located. The activities an organization carries out its sustainability performance. Full compliance of this performance with the relevant natural and biological environment is greatly important. That’s why the main point discussed in this study is the environmental sustainability performance of the port enterprises. As the competencies of port managers pay an important role in this performance, this study aims to scrutinize and evaluate these competencies of port operation managers in particular. To determine these competencies, a three-step Delphi technique has been used. This technique has been conducted through an expert group of 13 academicians. The results revealed 15 competency items. The identified competencies are believed to contribute to the effective process of selecting/employing managers in port organizations which will ensure corporate sustainability.
Influence of microcredit and business management training to micro and small business performance in West Java, Indonesia

— Micro, Small, and Medium Enterprises (MSMEs) are the backbone of national economy. However, there are still many problems faced by SMEs among other are the availability of capital, the difficulties to access finan-cial institution as a lender, low understanding in business management, limited market access, and lack of sci-ence and technology mastery. This study aims to analyze the effectiveness of microcredit financing provided by banks and business management training on MSMEs performance. The method used in this research is mixed method using Sequential Explanatory Analysis. Quantitative data was analyzed with Partial Least Square (PLS) and to convert ordinal data into interval data this study used Rasch Model. The subject of this study is the customers who are getting microcredit loan from Jabar-Banten Bank (BJB) located in Regional 1. The results show that microcredit financing and business management training partially have a positive and significant impact on the performance of MSMEs with path coefficients 8.352, which is bigger than 1.96 (t-stat). It means that good quality of microcredit and the good quality of training on business man-agement would result in a better business performance for MSMEs.
Do Response Styles Affect Estimates of Growth on Social-Emotional Constructs? Evidence from Four Years of Longitudinal Survey Scores

Abstract Survey respondents employ different response styles when they use the categories of the Likert scale differently despite having the same true score on the construct of interest. For example, respondents may be more likely to use the extremes of the response scale independent of their true score. Research already shows that differing response styles can create a construct-irrelevant source of bias that distorts fundamental inferences made based on survey data. While some initial studies examine the effect of response styles on survey scores in longitudinal analyses, the issue of how response styles affect estimates of growth is underexamined. In this study, we conducted empirical and simulation analyses in which we scored surveys using item response theory (IRT) models that do and do not account for response styles, and then used those different scores in growth models and compared results. Generally, we found that response styles can affect estimates of growth parameters including the slope, but that the effects vary by psychological construct, response style, and IRT model used.
Remnants of native forests support carnivore diversity in the vineyard landscapes of central Chile

Abstract Carnivores play an important role in ecosystem functioning as apex predators. However, most carnivore species are threatened or have been extirpated in human-dominated landscapes. The Mediterranean region of central Chile is a biodiversity hotspot, but expansion of agricultural areas such as vineyards is degrading wildlife habitat. We estimated the species richness and composition of carnivore communities in remnant fragments of sclerophyllous forest-shrubland in the vineyard landscapes of central Chile to evaluate the effects of human disturbance at different spatial scales. We tested two hypotheses: (1) vineyard landscapes with higher levels of human disturbance support a lower diversity of native carnivores in fragments of remnant native vegetation compared to landscapes with larger areas of natural habitat, and (2) habitat specialists and generalists respond differentially to human influence at the habitat vs landscape spatial scale. We used camera traps at 12 sites across the study area and evaluated the impact of human disturbance indicators on the richness and detection frequency of carnivore species. We found that human population density negatively affected carnivore richness and was associated with a lower detection frequency of the Vulnerable guiña Leopardus guigna. The presence of domestic dogs also had a negative effect on the detection frequency of the guiña and the two native species of foxes, the culpeo Lycalopex culpaeus and South American grey fox Lycalopex griseus. We conclude that protecting remnants of native forest in vineyard landscapes is crucial for carnivore conservation in central Chile.

On the Influence of Ultrasonic Surface Mechanical Attrition Treatment (SMAT) on the Fatigue Behavior of the 304L Austenitic Stainless Steel

The potential of ultrasonic surface mechanical attrition treatment (SMAT) at different temperatures (including cryogenic) for improving the fatigue performance of 304L austenitic stainless steel is evaluated along with the effect of the fatigue loading conditions. Processing parameters such as the vibration amplitude, the size, and the material of the shot medias were fixed. Treatments of 20 min at room temperature and cryogenic temperature were compared to the untreated material by performing rotating–bending fatigue tests at 10 Hz. The fatigue limit was increased by approximately 30% for both peening temperatures. Meanwhile, samples treated for 60 min at room temperature were compared to the initial state in uniaxial fatigue tests performed at R = −1 (fully reversed tension–compression) at 10 Hz, and the fatigue limit enhancement was approximately 20%. In addition, the temperature measurements done during the tests revealed a negligible self-heating (∆t < 50 °C) of the run-out specimens, whereas, at high stress amplitudes, temperature changes as high as 300 °C were measured. SMAT was able to increase the stress range for which no significant local self-heating was reported on the surface.
Effect of isometric training with short or long rest periods on Achilles tendon morphology : an ultrasound tissue characterization study

Achilles tendon (AT) is the strongest tendon in the body. One of the major causes of AT pathology, chronic tendinopathy, is frequently due to excessive loading. Despite the risk of overuse injury, exercise training with appropriate mechanical loading parameters has been found to trigger an adaptation response in the AT. However, the influence of some loading parameters, such as the duration of rest periods between exercise repetitions, remains unknown. Therefore, the aim of this study was to examine the effect of 10s rest insertion during isometric resistance training (Long rest training; LRT) on the morphological properties of human AT, compared with same training intensity and volume but with 3s rest insertion (short rest training; SRT). I hypothesized that ATs exposed to LRT would demonstrate increased tendon collagen organization and tendon cross-sectional area (CSA) compared with baseline, but that SRT would not demonstrate any change in either variable. To test my hypothesis, we recruited healthy adults, and randomly allocated one leg to LRT and the other to SRT. The exercise protocol consisted of 5 sets of 10 isometric calf presses at 90% of maximum voluntary contraction, three times a week over a 12-weeks training period. Tendon collagen organization (proportion of type I echoes) and CSA were measured by ultrasound tissue characterization before and after the 12-weeks period. The primary outcome was the proportion of type I echoes. In contrast to our hypothesis, neither LRT nor SRT induced an improvement in collagen organization or tendon CSA. However, tendons exposed to SRT demonstrated a reduction in the proportion of type I echoes following exercise from 0.66 (95% CI= 0.60 to 0.70) to 0.55 (95% CI=0.49 to 0.60), (p < 0.05), whereas tendons that were exposed to LRT didn’t demonstrate any reduction in the proportion of type I echoes from baseline (0.60, 95% CI= 0.56 to 0.65) to post-intervention (0.62, 95% CI= 0.57 to 0.67), (p = 0.58). Neither type

The Prevalence of Atypical Pneumonia Caused by Mycoplasma pneumoniae (P1 gene) in Patients with Respiratory Infections by Culture and Molecular PCR Methods in Tehran, Iran

Background: Atypical pneumonia is an upper and lower respiratory tract infection. Mycoplasma pneumoniae is a major cause of community-acquired pneumonia (CAP). Objectives: The present study aimed to determine the prevalence of atypical pneumonia caused by M. pneumonia by culture and molecular PCR methods in Tehran. Methods: In the present study, 102 samples of throat swab were collected from patients with respiratory infections. All samples were cultured in liquid PPLO Broth And solid PPLO agar media (1% glucose and 20% horse serum). The PCR technique with specific primers was implemented after culture and genome extraction through phenol-chloroform technique. Results: In this study, 27 (26.47%) colonies of Mycoplasma were isolated on PPLO agar medium. Using specific primers, it was found that 33 samples (32.4%) were positive in terms of Mycoplasma genus and 14 samples (13.7%) were positive for the presence of M. pneumonia. Conclusions: Mycoplasma pneumonia is a pathogen that causes respiratory tract infections in humans. Molecular PCR method is a quick and sensitive technique that has higher sensitivity and specificity than other methods. The obtained results may contribute to the specific treatment of some patients with symptoms of respiratory infections.
Antimicrobial Stewardship (AMS) in the Community

The importance of improving outpatient antibiotic use is acknowledged, but no comprehensive recommendations to curb the use in this setting have been made because of the lack of sufficient data to guide such efforts. A targeted application of antimicrobial stewardship (AMS) principles to the ambulatory setting has the potential to affect the most common indications for systemic antibiotic use in that the majority (80%) of antibiotic use occurs in the community, with acute respiratory-tract infections being the most common indication. However, the reasons driving the excessive prescription of antibiotics in the community are complex and include constraints on the consultation time, the lack of appreciation of the impact on resistance, considerable diagnostic uncertainty, and perhaps most importantly patient and parental pressures in conjunction with patient satisfaction surveys. Thus, in contrast to institutionalized AMS, few recommendations for outpatients are offered, largely because of the paucity of data regarding effective interventions to tackle such complex issues in ambulatory care. Prescribing antibiotics for patients with self-limiting conditions is counterproductive as it reinforces the belief that antibiotics are beneficial and encourages repetitive prescriptions and consultations. Hence, one of the ultimate goals of a community AMS program should be “demedicalization” of self-limiting acute infections. In this regard, multifaceted interventions where educational interventions occur on many levels may be applied successfully to communities after addressing local barriers to change. These appear to be the only interventions with effect sizes of sufficient magnitude to potentially reduce the incidence of antibiotic-resistant bacteria.
Transmit Antenna Selection for Full-Duplex Spatial Modulation Multiple-Input Multiple-Output System

Transmit antenna selection (TAS) is an effective solution to enhance the performance of a multiple-input multiple-output (MIMO) system, especially when combined with spatial modulation (SM), and full duplex (FD) technique. However, there still lacks a comprehensive understanding on the system behavior of such a system. In this article, we consider a point-to-point bidirectional FD-SM-MIMO system using channel gain based TAS under the impact of imperfect successive interference cancellation and develop an analytical solution for analyzing its performance. In particular, we derive the exact closed-form expressions of the outage probability (OP) and the symbol error probability (SEP) for the FD-SM-MIMO system with TAS. The analytical solution can also be used for evaluating the performance of the half-duplex SM-MIMO (HD-SM-MIMO) systems with and without TAS. The OP, SEP, and system throughput of the FD-SM-MIMO system with TAS are evaluated against the case without using TAS and the HD-SM-MIMO system to demonstrate the benefits of using TAS and impact of the residual self-interference. All analysis results are validated by the Monte Carlo simulation ones to confirm the correctness of the derived mathematical expressions.
Morphometric Analysis of the Foramen Magnum

The foramen magnum is morphometrically typified by two perpendicular diameters and a distinct margin. This important anatomical landmark is subject to high interindividual variation. The objective of this study was to evaluate the dim nsions and morphology of the foramen magnum in a Jordanian population. In this retrospective study, 247 individuals were consecutively sampled using the institutional picture archiving and communication system. The anteroposterior and transverse diameters of the foramen magnum were measured; the foramen magnum index was calculated; and, the shape of the foramen magnum was visually assessed. The sex-pooled anteroposterior and transverse diameters were 35.1 ± 3.2 mm and 29.3 ± 2.5 mm, respectively. The sex-pooled foramen magnum index was 1.20 ± 0.10. The diameters were significantly different (P<0.001) and positively correlated (r=0.52, P<0.001). Participant age was negatively correlated with the anteroposterior (r s =-0.15, P=0.02) and transverse (r s =-0.14, P=0.03) diameters. After controlling for participant age, there was a statistically significant difference in the anteroposterior diameter (P<0.001), th e transverse diameter (P<0.001), and the foramen magnum index (P=0.02) between sexes. The foramen magnum was most commonly irregular in shape (36 % of all cases). In contrast to previous studies, we report, for the first time, a negative correlation between age a nd the diameters of the foramen magnum. In addition, a predominance of irregularly shaped foramen magnum was found. The finding makes an already heterogenous group of published data even more variable, prompting reconsideration of the role of visual assessment in morphometric studies.
Numerical Study on Mixed Convection Heat Transfer Enhancement in a Long Horizontal Channel Using Periodically Distributed Rotating Blades

A numerical study has been conducted on mixed convection heat transfer enhancement in a long horizontal channel provided with periodically distributed rotating blades. The upper wall of the channel is maintained at a constant low temperature (Tc) while the lower wall is kept hot at a constant high temperature (Th). A series of rotating blades having negligible thickness in comparison to its length is placed periodically along the centerline of the channel with the spacing between two successive blades’ rotational axes being equal to the height of the channel under consideration. The mathematical model of the present problem is governed by two-dimensional laminar transient continuity, momentum and energy equations. The governing equations are transformed to non-dimensional forms and then the moving mesh problem due to blade motion is solved by implementing Arbitrary Lagrangian-Eulerian (ALE) finite element formulation with triangular discretization scheme. Three different working fluids have been considered such as water, air and liquid Gallium that essentially cover a wide range of Prandtl Number (Pr) from 0.026 to 7.1. The dynamic condition of the rotating blades has been represented by Reynolds Number (Re) that is varied in the range of 1 to 500 and its effect on fluid flow and heat transfer has been investigated for the case of pure mixed convection heat transfer, characterized by Richardson number (Ri) of unity. Numerical results have been presented and analyzed in terms of the distribution of streamline and isotherm patterns, spatially averaged Nusselt number and normalized average Nusselt number variation along the hot wall for different parametric system configurations. The results of the present study show that, presence of rotating blades increases the heat transfer significantly in the channel. Heat transfer increases with increasing Prandtl Number (Pr) and the enhancement becomes more significant at higher Reynolds Numbers (Re). Power Spectrum analysis in frequency domain obtained from the FFT analysis indicates that, the rotating blade oscillation frequency and the oscillation frequency of Nusselt number differ at higher range of Reynolds Number (Re) and Prandtl Number (Pr). Therefore, dynamic condition of the rotating blades together with the thermophysical properties of working fluid play vital role in modulating the heat transfer characteristics and fluid flow behavior within the long horizontal channel.
