High performance management practices in owner-managed SMEs

Objectives: While there is extensive management and academic literature on the topic area of high performance management practices (HPPs) internationally, research on HPPs in the Australian context is limited. Furthermore, research on HPPs has focused predominantly on large organisations and is largely a new direction for research in SMEs. This study attempts to fill some of the gaps in existing studies by considering a wide range of HPPs in Australian SMEs, with particular focus on owner managed SMEs. The objective of this paper is to examine the extent and nature of HPPs in owner managed Australian SMEs and the impact of certain organisational characteristics on these practices. The research questions under examination include: What is the prevalence of HPPs in owner managed Australian SMEs?; and what is the impact of firm size, the presence of a HR manager, and the existence of a strategic plan on HPPs in SMEs? Prior work: Undertaking this research is justified on the basis of: there is a gap in the theory relating to HPPs in SMEs and in particular owner managed SMEs, owing to the fact that most studies on HPPs are based in large organisations; globalisation and the pace of economic change are forces that are driving the need for greater understanding of HPPs (Burke 2002); and there are high expectations for growth and performance of SMEs in the economic growth and development plans for the Asia Pacific and Australian region (Asia Pacific Economic Cooperation 2002). Approach: A survey questionnaire was sent out to 4000 Australian small and medium-sized enterprises (35% response rate). A Dun and Bradstreet database was used and a stratified sample employed. A chi-square analysis was employed to determine whether there were significant differences in relation to high performance practices in small vs. medium organisations, SMEs with and without a HR manager; and organisations with and without a strategic plan. Results: The results of this study indicate that the overall picture regarding the incidence of high performance practices in Australian owner managed SMEs looks quite bleak. Significant positive relationships were found between demographic variables and HPPs in SMEs. Implications: Large firm solutions may not be appropriate. A more balanced approach to prescribing and researching management solutions in SMEs is needed; an approach with a greater emphasis on the SME sector. Value: This paper will provide an improved understanding of HPPs in Australian SMEs which will help the sector to better meet performance expectations

Impacts of Smooth Pigweed (Amaranthus hybridus) on Cover Crops in Southern Ontario

Amaranthus hybridus is a noxious weed in Ontario, with demonstrated allelopathic properties that can lead to decreased agricultural production. We tested the germination and growth of five cover crop species exposed to A. hybridus extracts, and to dried or fresh materials in soil. A germination index was calculated, and the dry weight of plant organs were measured to quantify responses to treatments. All species had reduced germination (≤29%) in 100% extract. Trifolium pratense had significant root weight reductions in extract (52%) and dried (72%) treatments, whereas shoot weight only decreased (48%) in dried treatment. Medicago sativa shoot weight decreased (52%) in 20g fresh treatment, while root weight decreased (62%) in dried treatment. Shoot weight of Raphanus sativus increased (32%) at mid-extract concentrations, while root weight increased (33%) only with dried treatment; however, both its shoot and root weight decreased (\u3e40%) in fresh treatment. Only the shoot weight of Lolium multiflorum increased (41% in 75% extract and 55% in dried treatment). Both Cichorium intybus shoot and root weights decreased (~50%) in fresh treatment. Crop responses to A. hybridus are complex, and material and species-dependant. Further testing in the field may provide a more comprehensive understanding of how to improve the management of A. hybridus

Market Signals Transmitted by Grid Pricing

Grid pricing improves the flow of information to producers, but market signals sent by grids may not be clearly understood. This study uses a two-stage Coefficients of Separate Determination process, four sets of fed cattle carcass data, and sensitivity analyses to identify market signals sent by grid pricing. Weight sends a stronger market signal than carcass quality characteristics such as quality and yield grade. Although grids are shaping production, market signals indicate that lower quality carcasses are penalized more than higher quality carcasses are rewarded. Sensitivity analyses suggest changes in quality and yield grade discounts have the greatest impact on market signals.beef cattle, Coefficients of Separate Determination, grid pricing, market signals, value-based marketing, Demand and Price Analysis,

Marshall Space Flight Center Research and Technology Report 2019

Today, our calling to explore is greater than ever before, and here at Marshall Space Flight Centerwe make human deep space exploration possible. A key goal for Artemis is demonstrating and perfecting capabilities on the Moon for technologies needed for humans to get to Mars. This years report features 10 of the Agencys 16 Technology Areas, and I am proud of Marshalls role in creating solutions for so many of these daunting technical challenges. Many of these projects will lead to sustainable in-space architecture for human space exploration that will allow us to travel to the Moon, on to Mars, and beyond. Others are developing new scientific instruments capable of providing an unprecedented glimpse into our universe. NASA has led the charge in space exploration for more than six decades, and through the Artemis program we will help build on our work in low Earth orbit and pave the way to the Moon and Mars. At Marshall, we leverage the skills and interest of the international community to conduct scientific research, develop and demonstrate technology, and train international crews to operate further from Earth for longer periods of time than ever before first at the lunar surface, then on to our next giant leap, human exploration of Mars. While each project in this report seeks to advance new technology and challenge conventions, it is important to recognize the diversity of activities and people supporting our mission. This report not only showcases the Centers capabilities and our partnerships, it also highlights the progress our people have achieved in the past year. These scientists, researchers and innovators are why Marshall and NASA will continue to be a leader in innovation, exploration, and discovery for years to come

IMPACT OF ALTERNATIVE GRID PRICING STRUCTURES ON CATTLE MARKETING DECISIONS

Quality grade, yield grade, and other feedlot performance factors explain much of the variation in profit under grid pricing. Thus, feedlot owners can change profits by adjusting time on feed to influence these performance factors. This research uses growth models, logistic regression, and an optimization process to determine how the optimal number of days on feed changes under different grid pricing structures. It was found that large quality or small yield discounts increases the optimal number of days on feed and small quality or large yield discounts result in fewer days on feed. Losses associated with a grid having large quality discounts are minimized as cattle fed for more days are able to obtain Choice premiums despite the discounts for more Yield Grade 4 and 5 carcasses. Given small quality discounts, cattle fed for a shorter length of time can obtain the Yield Grade 1 and 2 premiums without a large loss in revenue due to grading Select or Standard. Under cash pricing, cattle are fed for very long periods because there are no discounts applied to the carcasses and, therefore, the more weight they gain, the more revenue they generate. During periods of low feed prices, cattle can be fed longer so more cattle grade Prime but also have more Yield Grade 4 and 5 cattle.grid pricing, profits, animal growth, logistic regression, days on feed, Livestock Production/Industries, Marketing,

Effects of Lift Velocity on Muscle Activation During Leg Extension

It is not known if manipulating velocity within a prescribed resistance training mode will improve muscle activation. Muscle activations of the Rectus Femoris (RF), Vastus Lateralis (VL), Vastus Medialis (VM) and Bicep Femoris (BF) were examined during a leg extension exercise at 3 different velocities on 15 subjects (10men, 5 female, Age = 21.5 ± 1.8 yrs, Height = 171.2 ± 12.5 cm, Mass = 75.5 ± 16.3 kg). Trials of 1 set of 10 repetitions at 60% of 1RM, were performed at 15, 30 and 60º/s. Bipolar surface electrodes were placed over the BF, RF, VL, and VM. Micro-switches were utilized to identify the concentric (CON) and eccentric (ECC) phases of the lift. Data were sampled at 1024 Hz, filtered, rectified and the mean, integrated EMG calculated. One 2 x 4 x 3 (action x muscle x velocity) ANOVA with bonferonni adjustment was run and significance was followed by Tukey HSD post hoc analysis. Results indicated significantly greater activation of the VL, RF and VM for ECC extension at 60º/s compared to 15º/s. While 60º/s was also greater than 30º/s for the VL and VM during ECC. While comparing muscle action, CON VL, VM and RF were greater than ECC at 30º/sec, meanwhile VM CON was also greater at 15º/sec. No differences in muscle activation at any velocity or muscle action for BF were identified. We conclude that muscle recruitment while training with a 60% 1RM load is maximized at a velocity of 60º/s during ECC activity and 15 or 30º/sec during CON
