Do Psychological Capabilities Really Matter? The Combined Effects of Psychological Capital and Peace of Mind on Work Centrality and In-role Performance

This study examined the combined effects of psychological capital (PsyCap) and peace of mind on work centrality and in role performance in a random sample of 231 employees (N = 231) drawn from two public sector banks in Quetta city, Pakistan. Survey method was used to collect data. Data were collected in two phases. Respondents reported their levels of psychological capital and peace of mind in phase one; and their work centrality and in role performance were rated by their supervisors in phase two. Multiple linear regression and correlation techniques were used for hypotheses testing. Results indicated a positive association among all study variables. It was found that PsyCap and peace of mind are significant predictors of work centrality and in role performance but the magnitude of their effects is different. Peace of mind emerged as a stronger predictor than PsyCap. Results also highlighted that work centrality may also be used as a criterion to predict in role performance. Thus, it is recommended that organizations should endeavor to ensure all factors that contribute to employees’ peace of mind and PsyCap.
Efficiency and Selectivity of Gill Nets for Assessing Fish Community Composition of Large Rivers

Abstract To evaluate the efficiency and selectivity of gill netting for assessing fish biodiversity in the upper Ohio River system, we compared the efficiency of five gill-net types for sampling large-bodied fishes (adult total length greater than 250 mm) during fall 2001 and spring and fall 2002. Mesh sizes ranged from 3.8 cm to 14 cm (bar measure). We set the gill nets in selected pools of the Allegheny, Monongahela, and Ohio rivers 186 times over three seasons for a total of 1,644 net-hours. Nets were attached to a variety of structures, including trees and rootwads, bridge pylons, lock and dam chambers, and channel marker buoys. Nets were fished from late evening to first light, and all fish captured were identified, enumerated, and released. A total of 823 individuals representing 30 species or hybrids were captured. All net types captured common carp Cyprinus carpio and flathead catfish Pylodictis olivaris, but we captured a significantly greater diversity of fishes in graded-mesh gill nets with sma.
Educational intervention in patients undergoing orthognathic surgery: Pilot study

Objective : This study was to assess the feasibility of educational intervention nusing printed materials and the appropriateness of the instruments chosen to assess the efficacy of the intervention in patients undergoing orthognathic surgery. Methods : Nonrandomized pilot study was conducted with eight patients. In the preoperative period, an educational intervention using printed material and the application of instruments for data collection was carried out; in the postoperative period, only data collection was carried out. Friedman, Wilcoxon, McNemar and Rasch’s statistical tests were applied in order to assess the variables and the instrument. Results : Significant findings with respect to trait anxiety ( p = .016), lower difficulty of patients to perform oral hygiene ( p = .008), mild pain ( p = .025), and moderate pain ( p = .046). For the knowledge test, Rasch analysis showed that the model did not fit, since easy questions were stacked in the lower limit of the map, which showed the need to reformulate some questions. Conclusions : The intervention was consistent, but it can only be confirmed as effective through a research with a control group. It was observed that the use of brochures could improve the management of the signs and symptoms experienced by the patients in the postoperative period.
THE RELATIONSHIP BETWEEN SCARCITY OF NATURAL RESOURCES AND THEIR REAL PRICES

There has been a long running concern about resource depletion. Some argue this concern is misplaced, while others consider it to be an urgent problem requiring immediate action. Economists suggest that long term prices, adjusted for inflation (real prices), provide a useful and effective indicator of resource scarcity. This study tests this hypothesis in consideration of the accepted theory that traditional price deflators, such as the US consumer price index, overestimate inflation-, and accordingly-, are likely to underestimate long term commodity prices. To investigate the usefulness of real prices as an indicator of scarcity, a case study of two metals considered to be expensive (platinum and rhodium) and two considered to be relatively inexpensive (copper and lead) was used. Real long term price indices were constructed and econometric analysis used to determine the direction and significance of long-term price trends and whether real prices were correlated with other scarcity indicators such as the Reserves-toproduction ratio. The results show, when an appropriate adjustment is made to the deflator, long-run trends in real metal prices are all upward, and there is a significant relationship between the real prices and scarcity indicators, such as the reserves-to-production ratios, for platinum and rhodium, but not for copper and lead. These findings suggest that real prices of platinum and rhodium are more affected by their scarcity, while copper and lead prices are likely to be more dependent on other factors such as high substitutability with other virgin and recycled materials.

Gender Dynamics in Small Scale Irrigation Agriculture among Smallholder Farmers in Lume District in the Central Rift Valley of Ethiopia

Ethiopian economy predominantly depends on rain-fed agriculture. The sector is anticipated to support the whole economy and to change its structure. However, the country is highly affected by drought and millions of people are left without sustenance frequently. As an option, small scale irrigation schemes are important to reduce vulnerability and increase productivity. In this aspect, it is important to consider the implication of gender in irrigation crop farming under small scale scheme. This study was aimed to investigate irrigation agriculture among smallholder farmers and gender dynamics in Lume district in the Central Rift Valley of Ethiopia. Both quantitative and qualitative data collection was used and purposive sampling technique was implemented to select four peasant associations in the district. Households were stratified into male headed households and female headed households and simple random sampling was used to proportionally select 165 households from both groups (135 male headed households and 30 female headed households). Key informant interview, focus group discussions and household survey were also used to collect primary data. The data analysis was carried out by using descriptive statistics, one way ANOVA and chi-square tests. Results of the study showed that there was a significant difference in irrigation crop preference between male and female headed households. Male headed households mostly prefer high value crops such as onion, tomato and cabbage, while female headed household prefer easily manageable and low water demanding crops. Results on engagement in management practices revealed that female headed household mainly participate in planting, weeding, hoeing, harvesting, while male headed household are widely involved in land clearing, cultivation, crop watering, disease and pest control and transporting. The study has concluded that gender has significant roles and implications in small scale irrigation agriculture through its direct influence in participation, labor division and crop preference. Finally, the study suggests that improving the involvement of female headed households in irrigation agriculture, special consideration should be given by government and non-governmental organization.

Short-Rate Expectations and Term Premia: Experiences from Hungary and Other Emerging Market Economies

This study focuses on the elements of short-dated forward yields in Hungary and other emerging market economies – short-rate expectations and the term premium – and the influences on their behaviour. The rate expectations are proxied by median values of analyst surveys. Principal components analysis shows that, during the sample period 2009–13, rate expectations and term premia in emerging market economies co-moved closely with the corresponding elements of US yields. The term premium appears to have been driven by global news events, and rate expectations less so. As for Hungary, the yield elements periodically followed the dynamics of factors in emerging market economies generally, but country-specific effects seem to have been important as well.Full publication: The Transmission of Unconventional Monetary Policy to the Emerging Markets
The crystallization of lava lakes

Thermal convection driven by the kinetic undercooling of solidification can produce compositional and textural variations in an initially uniform lava flow that is cooled predominantly from above. We show that such kinetic undercooling is sufficient to drive convection at high Rayleigh numbers even in shallow lava lakes. We then employ a theoretical model that includes the effects of convection at high Rayleigh number to make predictions of the complete evolution of the lava. We show that predictions of the rate of growth of solid crust at the surface of the lake do not differ much from predictions made by ignoring effects due to convection. However, convective motions do shorten the time for complete solidification because, when they are driven by kinetic undercooling, there is internal crystallization in addition to that occurring near the cooled upper boundary of the lava. This important effect, which is absent from purely conductive models, predicts stratification and zonation of the lava, in agreement with field observations. We also examine the effect of taking into account the heat transfer to the country rock below the lava lake, and determine how the evolution of the lava lake varies with the viscosity of the lava.
Validation of the Connor Davidson resilience scale (CD-RISC) as applied within the Thai context

This study evaluated the psychometric properties of the Thai version of the Connor Davidson Resilience Scale (CD-RISC), a 25-item self-report questionnaire developed to measure resilience. This was achieved by testing the factor structure of the CD-RISC when applied to a non-clinical sample of Thai adults. Exploratory factor analysis identified three resilience factors: personal competence/tolerance of negative affect; support resources; and self-efficacy. Reliability analysis identified a number of items that were not internally consistent and these were deleted from the scale. The final Thai version of the CD-RISC consisted of 18 items, which is shorter than the original 25-item scale. The scale's convergent validity was tested by assessing the scale's relationship with three states of negative affect – depression, anxiety, stress – as measured by the 21-item Depression Anxiety and Stress Scale (DASS-21). Correlation analysis revealed that the three extracted resilience factors of personal competence/tolerance of negative affect; support resources; and self-efficacy are significantly and negatively correlated with the DASS-21 factors of depression, anxiety, and stress. The utility of the CD-RISC as applied within the Thai context is discussed.
An Ensemble Stacked Convolutional Neural Network Model for Environmental Event Sound Recognition

Convolutional neural networks (CNNs) with log-mel audio representation and CNN-based end-to-end learning have both been used for environmental event sound recognition (ESC). However, log-mel features can be complemented by features learned from the raw audio waveform with an effective fusion method. In this paper, we first propose a novel stacked CNN model with multiple convolutional layers of decreasing filter sizes to improve the performance of CNN models with either log-mel feature input or raw waveform input. These two models are then combined using the Dempster–Shafer (DS) evidence theory to build the ensemble DS-CNN model for ESC. Our experiments over three public datasets showed that our method could achieve much higher performance in environmental sound recognition than other CNN models with the same types of input features. This is achieved by exploiting the complementarity of the model based on log-mel feature input and the model based on learning features directly from raw waveforms.

This research paper aims at proving the importance of CSR for the enhancement of the performance of the organizations. The six companies that have been focused are listed in the Pakistani index. The CSR (independent variable) has been analyzed by two indicators and Organizational Performance (dependent variable) has been analyzed by another two. Both primary as well as secondary data has been used and for the analysis descriptive, regression and correlation methods have been adopted. The findings depict a highly positive correlation between ROA and turnover out of all while the standard deviation for turnover is also abnormal. Regression results are not significant and appear to be rejecting the proposed model. Also at the end some recommendations have been made that highlight the importance of CSR for the betterment of the performance of the organizations. The overall study is a guiding force for the managers and a helpful tool for future researchers Keywords: CSR, Organizational Performance, Stakeholder Perspective.
Water-use efficiency and productivity trends in Australian irrigated cotton: a review

Abstract. The aim of this review is to report changes in irrigated cotton water use from research projects and on-farm practice-change programs in Australia, in relation to both plant-based and irrigation engineering disciplines. At least 80% of the Australian cotton-growing area is irrigated using gravity surface-irrigation systems. This review found that, over 23 years, cotton crops utilise 6–7 ML/ha of irrigation water, depending on the amount of seasonal rain received. The seasonal evapotranspiration of surface-irrigated crops averaged 729 mm over this period. Over the past decade, water-use productivity by Australian cotton growers has improved by 40%. This has been achieved by both yield increases and more efficient water-management systems. The whole-farm irrigation efficiency index improved from 57% to 70%, and the crop water use index is >3 kg/mm.ha, high by international standards. Yield increases over the last decade can be attributed to plant-breeding advances, the adoption of genetically modified varieties, and improved crop management. Also, there has been increased use of irrigation scheduling tools and furrow-irrigation system optimisation evaluations. This has reduced in-field deep-drainage losses. The largest loss component of the farm water balance on cotton farms is evaporation from on-farm water storages. Some farmers are changing to alternative systems such as centre pivots and lateral-move machines, and increasing numbers of these alternatives are expected. These systems can achieve considerable labour and water savings, but have significantly higher energy costs associated with water pumping and machine operation. The optimisation of interactions between water, soils, labour, carbon emissions and energy efficiency requires more research and on-farm evaluations. Standardisation of water-use efficiency measures and improved water measurement techniques for surface irrigation are important research outcomes to enable valid irrigation benchmarks to be established and compared. Water-use performance is highly variable between cotton farmers and farming fields and across regions. Therefore, site-specific measurement is important. The range in the presented datasets indicates potential for further improvement in water-use efficiency and productivity on Australian cotton farms.
Some expected impacts of a solar energetic particle event at Mars

[1] The effect of a typical solar energetic particle event on the Martian atmosphere is described. Sputtering, Lyman α emission, atmospheric heating, and the radiation flux at the surface are calculated using a model of the solar wind interaction with the Martian atmosphere. The effect of the crustal magnetic field is also investigated. We provide estimates of the associated escape flux of neutral atoms and molecules. We compare the atmospheric energy deposition due to the incident solar energetic particles with the energy deposition due to other sources such as solar EUV/IR, solar wind protons and Martian energetic neutral atoms derived from pickup ions. We show that atmospheric sputtering efficiency is small compared with that for pickup ions for the present epoch but that the energy deposition at the homopause is important compared with the EUV/IR energy deposition. While some areas of the atmosphere are shielded from the incident flux by the crustal magnetic fields, the energetic particle flux reaching the surface is virtually unattenuated. This study of “space weather” at Mars raises a number of questions that need to be addressed with new observations and models.
Fiber optic dual EFPI/FBG for radiofrequency ablation monitoring in liver: ex-vivo experiments

We present a miniature and biocompatible fiber-optic sensing system, for specific application in monitoring of the radiofrequency thermal ablation (RFA) process. The sensing system is based on combination of Extrinsic Fabry-Perot Interferometry (EFPI) sensor for pressure detection, and Fiber Bragg Grating (FBG) for temperature measurement. The dual pressure/temperature measurement shows an extremely low cross-sensitivity. Measurements have been performed ex-vivo on porcine liver, recording several RFA procedures in different location. Maximum values of 164°C and 162 kPa have been recorded on the ablation point.
Prevention of Soccer-Related Ankle Injuries in Youth Amateur Players: A Randomized Controlled Trial

Background: In lower levels of play, the lateral ankle sprain is the most common time loss injury, especially amongst male youth soccer players. Purpose: The aim of the present study was to evaluate the effects of an injury prevention program on the incidence of ankle injuries in male youth amateur players. Study Design: Randomized controlled trial study. Methods: Fifty boys (mean ±SD: age 13.3±0.4 yr; body mass index of 20.9 ± 1.5 kg/m2; stature: 1.6 ± 0.1 m) from two sport schools, with 4.4 ± 0.5 years playing experience, participated. Players were randomly assigned to either an experimental (EXP, n = 25) or a control (CON, n = 25) group. A physical exercise program designed exclusively for youth male soccer players was combined with education of athletes and coaches to increase awareness of injury risk. Over 1 year all injuries were documented monthly by physiotherapist. Complete monthly injury reports were available for 50 players. Results: Nine ankle injuries occurred in the EXP group and 20 injuries occurred in the CON group, corresponding to incidence rates of 0.96 and 2.16, respectively, per 1000 player hours, which equates to 55% fewer injuries in the EXP group. Conclusions: The incidence of ankle injuries among youth male soccer players can be reduced by implementation of a multifaceted, soccer-specific physical exercise program. Coaches and players need better education regarding injury prevention strategies and should include such interventions as part of their regular training.
Do They Walk the Talk? Gauging Acquiring CEO and Director Confidence in the Value Creation Potential of Announced Acquisitions

We explore whether acquiring CEOs and directors act consistently with the idea that their newly announced acquisitions will increase long-term firm value. Specifically, we examine postannouncement adjustments to CEOs’ equity-based holdings and find acquiring CEOs tend to exercise options and sell firm stock following acquisition announcements. Moreover, positive short-term market performance exacerbates this effect. Further, we find directors tend to grant their acquiring CEOs stock options, after acquisition announcement, presumably to more tightly align CEO-shareholder interests. These findings suggest that when CEOs and directors manage acquiring CEOs’ equity-based holdings, they do not appear to anticipate long-term value creation from their acquisitions.
On Application of PHY Layer Abstraction Techniques for System Level Simulation and Adaptive Modulation in IEEE 802.11ac/ax Systems

This paper investigates the application in IEEE 802.11ac/ax systems of received bit information rate (RBIR) technique in order to estimate the effective signal-to-interference-plus-noise ratio used to abstract the physical layer (PHY) performance in system level simulations. The RBIR technique is evaluated based on simulation results of 802.11ac PHY operating over both canonical flat fading and independent and identical distributed and spatial-correlated frequency selective single-user and multi-user multiple input multiple output channels. We have concluded that RBIR PHY abstraction methodology is accurate enough to provide first order insights on system level performance and design options with reduced computational complexity. Finally, it is also described the application of RBIR PHY abstraction scheme to schedule on the flight the modulation code scheme that achieve a target quality-of-service.
Measurement of electromagnetic pulses generated during interactions of high power lasers with solid targets

A target irradiated with a high power laser pulse, blows off a large amount of charge and as a consequence the target itself becomes a generator of electromagnetic pulses (EMP) owing to high return current flowing to the ground through the target holder. The first measurement of the magnetic field induced by the neutralizing current reaching a value of a few kA was performed with the use of an inductive target probe at the PALS Laser Facility (Cikhardt et al. Rev. Sci. Instrum. 85 (2014) 103507). A full description of EMP generation should contain information on the spatial distribution and temporal variation of the electromagnetic field inside and outside of the interaction chamber. For this reason, we consider the interaction chamber as a resonant cavity in which different modes of EMP oscillate for hundreds of nanoseconds, until the EMP is transmitted outside through the glass windows and EM waves are attenuated. Since the experimental determination of the electromagnetic field distribution is limited by the number of employed antennas, a mapping of the electromagnetic field has to be integrated with numerical simulations. Thus, this work reports on a detailed numerical mapping of the electromagnetic field inside the interaction chamber at the PALS Laser Facility (covering a frequency spectrum from 100 MHz to 3 GHz) using the commercial code COMSOL Multiphysics 5.2. Moreover we carried out a comparison of the EMP generated in the parallelepiped-like interaction chamber used in the Vulcan Petawatt Laser Facility at the Rutherford Appleton Laboratory, against that produced in the spherical interaction chamber of PALS.
