Abstract:
ABSTRACTMeasurements of growth rate, food intake and food conversion efficiency on 235 Hereford bulls, from the first 4 years of a selection experiment, were used to assess the effects of rearing method, dam age and year/season of birth. Bulls were either reared artificially from birth to 84 days of age, or reared on their own dam to 84 or 168 days of age, to examine whether non-genetic effects on performance could be reduced by early weaning. All bulls were performance tested on ad libitum feeding from 200 to 400 days of age. Artificially-reared bulls had lower live weights at the start of test, which led to higher food conversion efficiency on test. Bulls reared naturally to 84 days of age were least affected by dam age and year/season of birth and performed as well as those weaned at 168 days of age. Earlier weaning of bulls entering central performance tests would reduce these environmental effects on performance, and may increase the accuracy of identifying bulls with genetically-superior growth and efficiency.

Abstract:
Purpose – The purpose of this paper is to provide an initial analysis of the roles of functional capabilities in adopting environmental management practices (EMP) and improving environmental performance from an organizational capability perspective. Design/methodology/approach – By combing survey data and archival data from 121 UK-based manufacturing firms, this study explores the relationships among functional capabilities (marketing and operations), EMP and environmental performance. Findings – The results show that marketing and operations capabilities significantly affect EMP, which in turn leads to improved environmental performance. More specifically, this study finds that EMP fully mediates the relationship between marketing capability and environmental performance. Practical implications – The results of this study provide guidance for managers considering how to develop environmental capability in order to improve environmental performance. Originality/value – This study addresses a demonstrable gap in the existing literature that few empirical studies have explored the potential effects of functional capabilities on implementing EMP.

Abstract:
Purpose Corporate environmental expenditure has been a growing concern in recent years, yet mixed findings exist regarding its economic impact. The purpose of this paper is to explain the mixed relationship between environmental expenditure and economic performance from the natural-resource-based view. Design/methodology/approach Using Global Reporting Initiative survey data from 120 firms in 30 countries, this study uses PROCESS, a path-based analysis software, to test the moderation and mediation hypotheses in an integrated analytical model. Findings The findings show that environmental expenditure has a negative impact on economic performance through pollution prevention capability. In contrast, environmental expenditure has a positive impact on economic performance through product stewardship capability. Both effects are significantly strengthened when the firm is located in an environmentally munificent country. Practical implications This study intends to inform firm managers, especially those in environmentally munificent countries, to relocate their environmental expenditure to enhance firms’ economic performance. In particular, firms should focus more on the reduction of input, such as raw materials, energy, and water, instead of output, including emissions, effluents, and wastes. Originality/value The contrasting indirect effects of pollution prevention and product stewardship offer a viable explanation for the mixed findings in the existent literature on environmental expenditure from a new perspective.

Abstract:
Variation in pre- and post-release gamete environments can influence evolutionary processes by altering fertilization outcomes and offspring traits. It is now widely accepted that offspring inherit epigenetic information from both their mothers and fathers. Genetic and epigenetic alterations to eggs and sperm-acquired post-release may also persist post-fertilization with consequences for offspring developmental success and later-life fitness. In externally fertilizing species, gametes are directly exposed to anthropogenically induced environmental impacts including pollution, ocean acidification and climate change. When fertilization occurs within the female reproductive tract, although gametes are at least partially protected from external environmental variation, the selective environment is likely to vary among females. In both scenarios, gamete traits and selection on gametes can be influenced by environmental conditions such as temperature and pollution as well as intrinsic factors such as male and female reproductive fluids, which may be altered by changes in male and female health and physiology. Here, we highlight some of the pathways through which changes in gamete environments can affect fertilization dynamics, gamete interactions and ultimately offspring fitness. We hope that by drawing attention to this important yet often overlooked source of variation, we will inspire future research into the evolutionary implications of anthropogenic interference of gamete environments including the use of assisted reproductive technologies. This article is part of the theme issue ‘How does epigenetics influence the course of evolution?’

AN ABSTRACT OF THE THESIS OF Garrett P. Lunsford, for the Masters degree in Architecture, presented on July 10th 2009, at Southern Illinois University Carbondale. TITLE: ENVIRONMENTAL EFFECTS ON STUDENT PERFORMANCE MAJOR PROFESSOR: Dr. Walter Wendler With the increasing concern for sub par student performance in America, it has become more vital than ever for designers to create optimal learning environments. Student performance is significantly dependent on the quality of teaching as well as the pupil-instructor relationship. However, it is rare for even our best instructors to receive adequate performance from their students when teaching in poor environments. Research for more than 30 years has displayed explicit correlation between physical characteristics of school buildings and educational outcomes. These physical characteristics include lighting, acoustics, thermal control, indoor air quality, as well as class size. By taking each of these factors into consideration, architects can produce settings that do not hinder student performance. Better educated children today will make the world a smarter, improved, more sustainable environment tomorrow.

Full text
Abstract:
Current Structural Health Monitoring (SHM) research uses changes in a bridge’s behaviour to locate and quantify the damage in a structure. However the structural responses are also linked to environmental effects, such as its temperature and the traffic load. In order to understand a typical suspension bridge’s behaviour to environmental conditions, studies on the Tamar Suspension Bridge’s response to temperature and traffic are contained in this thesis. This was achieved by observing data collected from long-term monitoring systems installed on the structure, and simulated responses derived from a three-dimensional finite element model of the bridge. The data of the bridge have shown that the profile of the suspension bridge reconfigures when the temperature of its structure increases, causing the deck to sag and expand. The natural frequencies of the bridge were noted to drop during the day. Transient thermal responses were also indentified; the differing rates of warming up between the deck, towers and cables manifested in the structural responses of the bridge. Phenomena caused by the temperature differential across the bridge’s surface were also studied. Investigations on the effect of traffic demonstrated its additional mass causes the natural frequencies to decrease for certain modes. This was identifiable in the time series data, where the largest reduction in frequencies is during rush hours. The investigations have shown that the changes the modal frequencies and modal mass are dependent on the eccentricity of the traffic flow on the bridge, which may increase or decrease depending on the mode shape. The loading of an abnormally heavy trailer on the bridge has also demonstrated the deformation to the bridge’s quasi-static shape as the vehicle travelled across. The location of the vehicle on the bridge was also able to affect the modal properties of the suspension bridge, according to simulated results.

Abstract:
The performance of pigs reared commercially is often considerably below that of their potential as seen under good experimental conditions. At least some of this decrease in performance can be attributed to environmental stressors. The aims and corresponding chapters of this thesis were to; (1) Choose a suitable predictor of potential pig growth. (2) Develop a deterministic dynamic model to predict the effects of genotype and the nutritional and thermal environments on the voluntary feed intake, growth and body composition of growing pigs. (3) Test and evaluate the model developed in chapter 2 against experimental data from the literature. (4) Quantify the effects of social stressors on the performance of growing pigs and incorporate these into the previously developed model, including variation in ability to cope with encountered social stressors. (5) Extend the model to deal with individual pig variation. (6) Compare the variation predicted by the population model w ith that observed under experimental conditions. The Gompertz function was chosen as a predictor of potential pig growth and as the starting point for model simulation, i.e., to provide an upper limit to growth. It uses few parameters, holds over a wide degree of maturity and the values of its parameters can be estimated simply. Unconstrained voluntary feed intake, predicted from the current state of the pig and composition of the feed, is that required to achieve potential growth. Actual food intake and the consequent gain were predicted taking into account the capacity of the animal to consume bulk and its ability to maintain thermoneutrality. The physical environment, described by the ambient temperature, wind speed, floor type and humidity, sets the maximum and minimum heat the pig is able to lose and determines whether the environment is hot, cold or thermoneutral. Model predictions were generally in good quantitative agreement w ith the observed data over the wide range of treatments tested and give support to the models value and accuracy. The social environment was described by group size, space allowance, feeder space allowance and the occurrence or not of mixing. All of these factors may act as stressors and it is assumed in the model that they decrease performance by lowering the capacity of the animal to attain its potential. The parameter EX accounts for differences in ability to cope when exposed to social stressors. The introduction of individual variation in growth potential, initial state and EX allowed the mean population response to be compared with that of the average individual. Whether these responses differed depended in part upon the social stressors encountered. The addition of variation in initial state and EX allowed better estimates of the phenotypic variation observed in real experiments to be achieved. The developed simulation framework is able to explore, and at least in principle, predict the performance of both individuals and populations differing in growth potential, initial state and ability to cope when raised under given dietary, physical and social environmental conditions. One of the main advantages of simulation models is that they allow the effects of a multiple factors on animal performance to be considered simultaneously, including any interactions that may exist, in a way that cannot be done by direct experimentation. These interactions may be crucial in decision-making processes as different individuals and populations may react differently in response to the same environmental stressors.

Abstract:
The aim of this thesis was to investigate how physiological and environmental factors affect surfing performance. Studies were performed that assessed the effect of anthropometric and physiological characteristics of surfers on rank and ability, the effect of creatine supplementation on surfing performance and the effect of wave size, wave period and the ability of surfers on physiological and performance indices of surfing. Study one investigated the effect of the anthropometric variables on rank and rating of ability. This was measured across a sample of 79 surfers ranging from intermediate to professional surfers. Significant correlations were found for endomorphy (r = -0.366, P <0.01), sum of six skinfolds (r = -0.274, P <0.05), Body fat percentage (r = -0.268, P <0.01) and mesomorphy (r = 0.442, P <0.01). Findings suggest that levels of adiposity and muscularity might influence the potential for progression between intermediate and professional level surfing performance. Study two investigated the effect of physiological variables on the national ranking of 18 elite male junior surfers using assessments of maximal oxygen uptake, lower body explosive power, upper body power, agility, and balance. Partial correlations were used to account for the influence of age within the sample and a significant correlation was found between power output at (rp = -0.879, P <0.01). Findings suggest that power output at is an important factor for achieving competitive success in high performance junior surfers. Study three investigated the effect of short term (20g.day-1 for 5 days) creatine supplementation on body composition, repeated upper body anaerobic power and competition performance was assessed in 17 club level surfers. Testing comprised assessment of body mass and total body water using bioelectrical impedance analysis, a repeated upper body Wingate based on time motion analysis of competitive surfing. A two-way repeated measures ANOVA found no significant effects of supplementation on laboratory measures of anaerobic power or competitive performance. The fourth study investigated the effects of changes in wave conditions on physiological response and performance parameters of surfing. This was assessed using 39 surfers who participated in 60 surfing sessions where wave conditions were recorded and performance was measured using GPS. The study found that wave height was significantly related to energy expenditure (rp =-0.351, P <0.05), maximum ride speed (rp = 0.866, P <0.01), the standard deviation of maximum ride speeds (rp = 0.654, P <0.01), mean ride time (rp = 0.354, P <0.01), maximum ride time (rp = -0.296, P <0.05), the standard deviation of the ride times expenditure (rp = -0.344, P <0.01), mean ride distance (rp = 0.398, P <0.01), maximum ride time (rp = 0.318, P <0.05), minimum ride distance (rp = 0.268, P <0.05), standard deviation of the ride distances (rp = -0.362, P <0.01), percentage of total distance riding (rp = 0.310, P <0.05), percentage of time spent waiting (rp = -0.272, P = 0.05), percentage of total time spent riding (rp = 0.396, P < 0.01), percentage of total time in miscellaneous activities (rp = 0.471, P <0.01), total distance riding (rp = 0.310, P =0.05), total distance per hour (rp = 0.427, P <0.01). Wave period was found to be significantly related to average heart rate as a percentage of maximum (rp = 0.490, P <0.01), the percentage of time spent in the “easy” training zone (rp = -0.408, P <0.01), maximum ride speed (rp = 0.371, P <0.01), mean ride time (rp = 0.283, P <0.05), maximum ride distance (rp = 0.279, P <0.05), and the standard deviation of the ride distances (rp = 0.325, P <0.05). The ability levels of the surfers were found to be significantly related to average heart rate as a percentage of maximum (rp = -0.412, P <0.01), percentage of time in the “steady” zone (rp = 0.435, P <0.01), percentage of time in the “intermittent” zone (rp = 0.483, P <0.01), maximum ride speed (rp = 0.454, P <0.01), mean ride distance (rp = 0.392, P <0.05), standard deviation of the ride distances (rp = 0.264, P <0.05), percentage of the total distance riding(rp = 0.267, P <0.05), percentage of time paddling (rp = 0.364, P <0.05), percentage of time in miscellaneous activities (rp = -0.299, P <0.05), total distance riding (rp = 0.267, P <0.05) and average speed (rp = 0.428, P <0.01). This thesis has found that ability in surfing is related to anthropometric and physiological measures, creatine supplementation improves peak anaerobic power but does not significantly improve surfing performance in club level surfers and that wave conditions and the skill levels of surfers are significantly related to the physiological and performance parameters of surfing.

Abstract:
Global environmental change fundamentally affects plants and their interactions with other species, and this has profound impacts on communities and ultimately ecosystems. In order to understand the mechanisms involved, we need to elaborate on the combined effects of different global change drivers on multiple levels of plant organization, including the biochemical level (production of defence compounds), the whole organism, the population, and the plant-herbivore interaction level. This thesis investigates (1) the combined effects of factors related to climate change and habitat fragmentation on Brassica nigra and (2) the effects of Zn soil pollution on the heavy metal hyperaccumulator Noccaea caerulescens at these different levels. Common garden and greenhouse experiments with B. nigra applied drought stress and elevated CO2 to examine climate change impacts, while crossing treatments (inbreeding and between-population outbreeding) were used to investigate habitat fragmentation effects. Heterosis was lost under drought stress, and there were several interactive effects of the experimental treatments that varied within and among populations. In a greenhouse experiment with N. caerulescens, plants were grown on soil with different amounts of zinc. Plants had greater herbivore resistance when grown on Zn-amended soil, and invested more in herbivore tolerance when grown on soil without added Zn. In general, the results indicate that factors related to global environmental change have complex and interactive effects on different levels of plant organization. The findings are discussed in terms of their implications for ecology, evolution and conservation.

Abstract:
As environmental responsibility (ER) gains momentum in the corporate and stakeholder world, it is imperative to understand the relationship between ER and financial performance. While there is prior research looking at this relationship, this study provides further insight into the specific effects of negative and positive ER. In addition, it looks over the years 2008-2011 having implications for companies about the effects of their ER even through financial hardships. This study uses a widely respected corporate social responsibility database, in which ER scores were separated from. In this study, 287 firms in the S&P 500 are examined through times-series regression analyses. The results reveal that positive ER had a negative relationship with financial performance indicators Tobin’s q and ROA. However, negative ER had such strong positive relationship with financial performance in both measures, that when looking at the effect of net ER, the relationship was tipped back to positive. This indicates that negative ER worsens a company’s financial position more than spending on positive ER initiatives.

Quinn, Meghan. Geotechnical effects on fiber optic distributed acoustic sensing performance. Engineer Research and Development Center (U.S.), July 2021. http://dx.doi.org/10.21079/11681/41325.

Abstract:
Distributed Acoustic Sensing (DAS) is a fiber optic sensing system that is used for vibration monitoring. At a minimum, DAS is composed of a fiber optic cable and an optic analyzer called an interrogator. The oil and gas industry has used DAS for over a decade to monitor infrastructure such as pipelines for leaks, and in recent years changes in DAS performance over time have been observed for DAS arrays that are buried in the ground. This dissertation investigates the effect that soil type, soil temperature, soil moisture, time in-situ, and vehicle loading have on DAS performance for fiber optic cables buried in soil. This was accomplished through a field testing program involving two newly installed DAS arrays. For the first installation, a new portion of DAS array was added to an existing DAS array installed a decade prior. The new portion of the DAS array was installed in four different soil types: native fill, sand, gravel, and an excavatable flowable fill. Soil moisture and temperature sensors were buried adjacent to the fiber optic cable to monitor seasonal environmental changes over time. Periodic impact testing was performed at set locations along the DAS array for over one year. A second, temporary DAS array was installed to test the effect of vehicle loading on DAS performance. Signal to Noise Ratio (SNR) of the DAS response was used for all the tests to evaluate the system performance. The results of the impact testing program indicated that the portions of the array in gravel performed more consistently over time. Changes in soil moisture or soil temperature did not appear to affect DAS performance. The results also indicated that time DAS performance does change somewhat over time. Performance variance increased in new portions of array in all material types through time. The SNR in portions of the DAS array in native silty sand material dropped slightly, while the SNR in portions of the array in sand fill and flowable fill material decreased significantly over time. This significant change in performance occurred while testing halted from March 2020 to August 2020 due to the Covid-19 pandemic. These significant changes in performance were observed in the new portion of test bed, while the performance of the prior installation remained consistent. It may be that, after some time in-situ, SNR in a DAS array will reach a steady state. Though it is unfortunate that testing was on pause while changes in DAS performance developed, the observed changes emphasize the potential of DAS to be used for infrastructure change-detection monitoring. In the temporary test bed, increasing vehicle loads were observed to increase DAS performance, although there was considerable variability in the measured SNR. The significant variation in DAS response is likely due to various industrial activities on-site and some disturbance to the array while on-boarding and off-boarding vehicles. The results of this experiment indicated that the presence of load on less than 10% of an array channel length may improve DAS performance. Overall, this dissertation provides guidance that can help inform the civil engineering community with respect to installation design recommendations related to DAS used for infrastructure monitoring.

Abstract:
Right-turn lane (RTL) crashes are among the most key contributors to intersection crashes in the US. Different right turn lanes based on their design, traffic volume, and location have varying levels of crash risk. Therefore, engineers and researchers have been looking for alternative ways to improve the safety and operations for right-turn traffic. This study investigates the traffic safety performance of the RTL in Indiana state based on multi-sources, including official crash reports, official database, and field study. To understand the RTL crashes' influencing factors, we introduce a random effect negative binomial model and log-linear model to estimate the impact of influencing factors on the crash frequency and severity and adopt the robustness test to verify the reliability of estimations. In addition to the environmental factors, spatial and temporal factors, intersection, and RTL geometric factors, we propose build environment factors such as the RTL geometrics and intersection characteristics to address the endogeneity issues, which is rarely addressed in the accident-related research literature. Last, we develop a case study with the help of the Indiana Department of Transportation (INDOT). The empirical analyses indicate that RTL crash frequency and severity is mainly influenced by turn radius, traffic control, and other intersection related factors such as right-turn type and speed limit, channelized type, and AADT, acceleration lane and AADT. In particular, the effects of these factors are different among counties and right turn lane roadway types.
