title: Josh Hardy and the #SaveJosh Army: How Corporate Risk Escalates and Accelerates through Social Media
Creators: name: Larcker, David F.

Publisher: name: Corporate Governance Research Initiative
Year: 2014

description: On March 5, biotechnology company Chimerix refused to provide a potentially life-saving drug to 7-year old Josh Hardy who was battling cancer. The drug had not yet received FDA approval, and the company had discontinued its “compassionate use” program to dedicate resources to Phase 3 testing of the drug. One week later, following a massive social media onslaught that captured national attention, the company relented. In this Closer Look, we dissect the powerful force of social media and examine its potential impact on corporate reputation. We ask: Why aren’t more companies prepared to deal with the reputational risks that emerge through online channels? How should information gathered from social media outlets be used to supplement a comprehensive risk management program? Are stories such as this one a board-level issue? If so, at what point do they become one? If Chimerix were your company, what would you do differently?

title: Detailed Description and Nomenclature of High Resolution G-Banded Horse Chromosomes and Cytogenetic Analysis of Hereditary Multiple Exostosis in Horses
Creators: name: Maciulis, Alma
Publisher: name: Utah State University
Year: 1984

description: A reliable technique for obtaining late prophase, prometaphase and greater numbers of metaphase chromosomes is presented. The increased number of mitoses and high resolution chromosomes were obtained using a modification of the typical three-day blood culture technique in which the cell cycle was temporarily blocked at the G1-s border with methotrexate. A high resolution G-band idiogram is presented using a system similar to the standardization of human chromosomes. The use of this technique and system of nomenclature will facilitate routine analyses of horse chromosomes and provide a basis for the identification and recording of chromosome aberrations in this species. C-bands and NORs of the domestic horse are also described.
C-bands, NORs and high resolution G-bands of control horses were compared with those of horses affected with Hereditary Multiple Exostosis. No differences were found on NORs, C- and G-bands between control and exostosis horses.

description: In March 2013, Lululemon Athletica removed its inventory of women’s black yoga pants from its stores because recent shipments of the product were “too sheer.” For a company reliant on a reputation for quality, the news was devastating. Worse, the recall set off a series of PR related disasters that were largely of the company’s own making. We examine these events in greater detail, and ask: Why are companies so ill-prepared to manage risk? How can companies develop a reliable way to track and respond to risk? How can companies better manage social media risk? When do risk-related matters become a board-level issue?
Young People's Subjective Understandings of Early School Leaving in Rural Areas
Creators: name: Schmidt, MS
Publisher: name: University Of Tasmania
Year: 2023

description: This study explores young rural people's subjective understandings of their future educational choices in order to shed light on the relatively low educational retention rates of young Australians living in rural areas. Qualitative, semi-structured in-depth interviews were conducted and six students who had decided to continue their education were compared to seven students who had chosen to leave the education system completely or who were undecided about whether or not to continue their education. Using the theoretical framework of Bourdieu (1990), especially his concepts of social and cultural capital and the habitus, the data was analysed thematically. Key findings include that early school leaving was not so much linked to concerns about the challenges of negotiating the physical distance of attending College some distance away but to fears of being a stranger in a foreign land. The early school leavers perceived the decision to continue their education as risky because their social networks and knowledges were tied to the local area. For the continuing students this risk was minimised because previous contacts and understandings had enabled them to internalise the cultural knowledges and practices of the city. Whilst all the young people in this study had the same aspirations, the nature of their social and cultural capital shaped the way these aspirations were fulfilled.

description: Residential proximity to unconventional natural gas development (UNGD) has been shown to be associated with asthma exacerbations, but there is limited evidence regarding whether exacerbations are associated with a particular distance or phase of well activity. To study the impact of proximity to UNGD activity by well phase and buffer distance. We included asthma patients 5–90 years old with a primary diagnosis of asthma and at least one order for medications prescribed for asthma residing in one of eight Southwestern Pennsylvania counties between 2011 and 2020. We matched events (severe exacerbation, emergency department visit, hospitalization) by age group, sex, and year to cohort members without an event of the same or greater severity. The primary exposure measure was an inverse distance-weighted index of UNGD activity up to 10 miles of a patient’s residence. We fit a series of adjusted multilevel logistic regression models using tertiles of exposure activity by well phase and buffer distance. Our cohort consisted of 46,676 asthma patients. We found strong evidence for an increased risk specifically during the production phase for all buffer distances examined for all three event types, as based on consistent, statistically significantly elevated odds ratios. Elevations ranged from 2 to 8 times the baseline of no wells within 10 miles of the patient’s residence. This study provides evidence of increased risk of asthma events with the production phase. This should be considered in determining risk communication and assessment for these vulnerable populations, particularly during the production phase.

description: Network-on-Chips (NoCs) have become the standard communication platform for future massively parallel systems due to their performance, flexibility and scalability advantages. However, reliability issues brought about by scaling in the sub-20nm era threaten to undermine the benefits offered by NoCs. This dissertation demonstrates design techniques that address both reliability and security issues facing modern NoC architectures. The reliability and security problem is tackled at different abstraction levels using a series of schemes that combine information from the architecture-level as well as hardware-level in order to combat aging effects and meet secure design stipulations while maintaining modest power-performance overheads.

title: Direct Electrical Arc Ignition of Hybrid Rocket Motors
Creators: name: Judson, Michael I.
Publisher: name: Utah State University
Year: 2015

description: Hybrid rockets motors provide distinct safety advantages when compared to traditional liquid or solid propellant systems, due to the inherent stability and relative inertness of the propellants prior to established combustion. As a result of this inherent propellant stability, hybrid motors have historically proven difficult to ignite. State of the art hybrid igniter designs continue to require solid or liquid reactants distinct from the main propellants. These ignition methods however, reintroduce to the hybrid propulsion system the safety and complexity disadvantages associated with traditional liquid or solid propellants. The results of this study demonstrate the feasibility of a novel direct electrostatic arc ignition method for hybrid motors. A series of small prototype stand-alone thrusters demonstrating this technology were successfully designed and tested using Acrylonitrile Butadiene Styrene (ABS) plastic and Gaseous Oxygen (GOX) as propellants. Measurements of input voltage and current demonstrated that arc-ignition will occur using as little as 10 watts peak power and less than 5 joules total energy. The motor developed for the stand-alone small thruster was adapted as a gas generator to ignite a medium-scale hybrid rocket motor using nitrous oxide /and HTPB as propellants. Multiple consecutive ignitions were performed. A large data set as well as a collection of development 'lessons learned' were compiled to guide future development and research. Since the completion of this original groundwork research, the concept has been developed into a reliable, operational igniter system for a 75mm hybrid motor using both gaseous oxygen and liquid nitrous oxide as oxidizers. A development map of the direct spark ignition concept is presented showing the ow of key lessons learned between this original work and later follow on development.

description: We present a detailed study of the collapse of a spherical perturbation in DGP braneworld gravity for the purpose of modeling simulation results for the halo mass function, bias and matter power spectrum. The presence of evolving modifications to the gravitational force in form of the scalar brane-bending mode lead to qualitative differences to the collapse in ordinary gravity. In particular, differences in the energetics of the collapse necessitate a new, generalized method for defining the virial radius which does not rely on strict energy conservation. These differences and techniques apply to smooth dark energy models with w unequal -1 as well. We also discuss the impact of the exterior of the perturbation on collapse quantities due to the lack of a Birkhoff theorem in DGP. The resulting predictions for the mass function, halo bias and power spectrum are in good overall agreement with DGP N-body simulations on both the self-accelerating and normal branch. In particular, the impact of the Vainshtein mechanism as measured in the full simulations is matched well. The model and techniques introduced here can serve as practical tools for placing consistent constraints on braneworld models using observations of large scale structure.

description: Insulinotropic agents are a common class of antihyperglycemic drugs. Insulinotropic agents mainly include glinides and sulfonylureas. Because it can reduce postprandial blood glucose in patients with type 2 diabetes, it has been widely used in clinical practice. However, the rate of metabolism of such drugs varies in different patients, and doctors need to optimize treatment according to the metabolism of the drug in the patient’s body. Therefore, there is a need to establish rapid, environmentally friendly, and effective techniques for the analysis of insulinotropic agents in substances, such as biological samples. In this paper, the pretreatment and analysis methods for insulinotropic agents in various samples since 2014 were summarized in detail. Pretreatment techniques encompass liquid-liquid extraction, liquid phase microextraction, solid phase extraction, and solid phase microextraction, with the latter, particularly when employing innovative nanomaterials, showcasing heightened extraction efficiency and expedited enrichment times. Analytical methodologies encompass liquid chromatography-based techniques, sensor approaches, among others. Notably, electrochemical sensors harnessing novel materials have significantly enhanced detection sensitivity. Furthermore, the review comprehensively examines technologies and materials aligned with green chemistry principles, highlighting future research avenues for the eco-friendly pretreatment and detection methodologies of insulinotropic agents. Pretreatment and analysis methods for insulinotropic agents were reviewed and compared.Advantages and disadvantages of different pretreatment methods and analysis methods were described.New materials and solvents in SPE and SPME methods were introduced.

Investigation of learning by discovery

Publisher: name: University of British Columbia
Year: 2011

description: The problem was to determine whether or not a discovery method of teaching for transfer was superior to an expository-method of teaching for transfer. The experiment was a comparison of the transfer effects of an unverbalized awareness and a verbal reception method of instruction. It was expected to have implications regarding the theories of Hendrix and Ausubel about transfer of training. The central problem was to compare the transfer effects of eliminating or delaying the verbalization by students of their discoveries, with those obtained by didactic presentation using Ausubel's "introductory organizers". The experiment involved ten eighth grade classes taught by six teachers. All classes and teachers were from the public school system of British Columbia. Four classes were taught by each of the experimental methods and two classes comprised a control group. The teaching involved four days of instruction on some of the introductory aspects of the language of sets. A test for transfer was administered on the fifth day. An attempt was made to ensure that the essential difference between the experimental methods lay in the unverbalized awareness - verbal reception variable rather than in some other variable. For example, the amount of teaching time, the sequence of presentation of the topics, the number and kinds of examples used, and the daily assignments were the same for each group. The mental age and the previous mathematics achievement of the groups were covaried. The verbal reception samples scored higher on the transfer task than the unverbalized awareness samples, when initial differences on these covariates were statistically eliminated. The differences were not significant at the five percent level. It was concluded that, under conditions which existed in this experiment, there was no basis for considering either method to be superior in facilitating transfer.

The dependence on the principal quantum number (n) of the ns, nd, and np initial states is investigated up to n = 100 for the nonresonant emissions. For the ns states together with the main E1E1 channel the contributions of higher multipoles (M1M1, E2E2, E1M2) are considered. For the np states the E1M1 and E1E2 channels are evaluated. Moreover, the simple analytical formula for the E1M1 decay is derived in the nonrelativistic limit.

description: The shareholders of public corporations have considerable interest in the choice of individual to serve as CEO of their company. They want to be assured that the company has a viable plan in place to replace the current CEO if necessary. Historically, boards have deferred to outgoing CEO, allowed them to pick their own successors. Current governance standards have moved away from this practice. And yet several companies today still defer to the recommendation of the CEO when making a final decision. We discuss handpicked successors in greater detail and ask: Under what conditions are they likely to succeed? When are they more likely to fail? How does the board gain access to the valuable information that a CEO can offer about potential candidates, without it being inappropriately filtered by personal bias? When should the board exclude the outgoing CEO from the selection process?

description: Higgs singlet superfields, usually present in extensions of the Minimal Supersymmetric Standard Model (MSSM) which address the $μ$-problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric Standard Model (mnSSM), can have significant contributions to $B$-meson flavour-changing neutral current observables for large values of $\tanβ\gsim 50$. Illustrative results are presented including effects on the $B_s$ and on the rare decay $B_s\toμ^+μ^-$. In particular, we find that in the NMSSM, the branching ratio for $B_s\toμ^+μ^-$ can be enhanced or even suppressed with respect to the Standard Model prediction by more than one order of magnitude.

description: Abstract

The objective of this study was to examine the efficacy of digital-based management service systems in enhancing the quality of education management in North Gorontalo Regency Junior High School. This study employs a descriptive qualitative research approach. Data were collected through observation, interviews, and document analysis. The findings indicate that digital-based management services at North Gorontalo Regency Junior High School are commendable, particularly at SMPN 1 Kwandang and SMPN 2 Kwandang. The digital-based services at SMPN 1 Kwandang are exemplified by the online registration system, which eliminates the necessity for parents to queue to register their children. Furthermore, SMPN 1 Kwandang has a school website, which provides parents with convenient access to school-related information. The digital-based services at SMPN 2 Kwandang are exemplified by the Go Paperless School Innovation Program, which was initiated by the Regent of North Gorontalo Regency. The program is still operational and is utilized primarily for the administration of examinations. In the event that a student lacks the requisite technological resources, the school provides tablets that can be borrowed for the duration of the examination. Conversely, digital-based management services at SMPN 3 Anggrek are still in their infancy. The service system in this school is still in a developmental phase due to the school's relatively recent establishment. The school's remote location from the city center also impedes the implementation of digital-based service systems due to the constrained internet network.

description: Complex systems are successfully reduced to interacting elements via the network concept. Transport plays a key role in the survival of networks. For example the specialized signaling cascades of cellular networks filter noise and efficiently adapt the network structure to new stimuli. However, our general understanding of transport mechanisms and signaling pathways in complex systems is yet limited. Here we summarize the key network structures involved in transport, list the solutions available to overloaded systems for relaxing their load and outline a possible method for the computational determination of signaling pathways. We highlight that in addition to hubs, bridges and the network skeleton, the overlapping modular structure is also essential in network transport. Moreover, by locating network elements in the space of overlapping network modules and evaluating their distance in this "module space", it may be possible to approximate signaling pathways computationally, which, in turn could serve the identification of signaling pathways of complex systems. Our model may be applicable in a wide range of fields including traffic control or drug design.

description: We study issues concerning perturbative integrability of N=6 Chern-Simons theory at planar and weak `t Hooft coupling regime. By Feynman diagrammatics, we derive so called maximal-ranged interactions in the quantum dilatation generator, originating from homogeneous and inhomogeneous diagrams. These diagrams require proper regularization of not only ultraviolet but also infrared divergences. We first consider standard operator mixing method. We show that homogeneous diagrams are obtainable by recursive method to all orders. The method, however, is not easily extendable to inhomogeneous diagrams. We thus consider two-point function method and study both operator contents and spectrum of the quantum dilatation generator up to six loop orders. We show that, of two possible classes of operators, only one linear combination actually contributes. Curiously, this is exactly the same combination as in N=4 super Yang-Mills theory. We then study spectrum of anomalous dimension up to six loops. We find that the spectrum agrees perfectly with the prediction based on quantum integrability. In evaluating the six loop diagrams, we utilized remarkable integer-relation algorithm (PSLQ) developed by Ferguson, Baily and Arno.

Interactive visualisation techniques for data mining of satellite imagery
Creators: name: Welch, SJ
Publisher: name: University Of Tasmania
Year: 2023

description: Supervised classification of satellite imagery largely removes the user from the information extraction process. Visualisation is an often ignored means by which users may interactively explore the complex patterns and relationships in satellite imagery. Classification can be considered a 'hypothesis testing' form of analysis. Visual Data Mining allows for dynamic hypothesis generation, testing and revision based on a human user's perception. In this study Visual Data Mining was applied to the classification of satellite imagery. After reviewing appropriate techniques and literature a tool was developed for the visual exploration and mining of satellite image data. This tool augments existing semi-automatic data mining techniques with visualisation capabilities. The tool was developed in IDL as an extension to ENVI, a popular remote sensing package. The tool developed was used to conduct a visual data mining analysis of high-resolution imagery of Heard Island. This process demonstrated the positive impacts of visualisation and visual data mining when used in the analysis of satellite imagery. These impacts consist of: increased opportunity for understanding and hence confidence in classification results, increased opportunity for the discovery of subtle patterns in satellite imagery and the ability to create, test and revise hypotheses based on visual assessment.
Fragments : beyond the object
Creators: name: Hamilton, DW
Publisher: name: University Of Tasmania
Year: 2023

description: The project is an investigation of processes that contrive to influence how visual objects are viewed and interpreted. I believe that all artworks are composed of a combination of physical and conceptual fragments, with the physical object constituting but a small yet important part of the viewer's perceptual experience. To me, the role of an art object is to be a specifically crafted initiator, setting in train a process that builds a vision of a whole that is more than the object itself. I contend that a fragment of an artwork has a definite edge, a point where its physical being ceases, but also marking a transition where an ambiguity begins: there is an unseen continuation which surrounds all art objects. This is explored through an overview of the fragment, particularly in Western sculptural and light forms. In a metaphoric sense, the undefined and ephemeral space beyond the object is inhabited by elements that fall in and out of focus: it is a place where cognition of them is always fleeting. It is these parts, not physically represented by the object, but merely inferred as a consequence of the object, that are the subject of investigation. The perceived space beyond the physical object is never completely decoded and never fully confirmed, yet is essential to the understanding of the art object. Fragments: Beyond the Object sets out to portray this mind-projected space surrounding the art object, what Heidegger identifies as this 'nothingness'. I use two-dimensional manipulated images and the play of light to suggest both a fragment and its surrounding space. The installation tests the possibilities of the extension of human perception, seeking to find how little is physically needed for the mind to apprehend an object, to evolve for it an acceptable form, so that it is imagined and understood in three dimensions.

title: Redox-Controlled Biogeochemical Processes Affecting Arsenic Solubility in Sediments from a Basin-Fill Aquifer in Northern Utah
Creators: name: Meng, Xianyu
Publisher: name: Utah State University
Year: 2015

description: The basin-fill aquifers of the American Southwest host elevated concentrations of arsenic in groundwater due to the local geology. Limited information is available on arsenic dynamics in semi-arid and arid regions of the world. This study describes arsenic biogeochemistry and mechanisms of arsenic solubilization for a soil profile collected from the surface to the depth of groundwater in the Cache Valley Basin, Northern Utah.
The first objective was to delineate mechanisms of arsenic solubilization from sediments collected at the study site. Microcosms containing site groundwater and siteoxidized and site-reduced sediments, were monitored over time to observe changes in the solubilization and oxidation state of arsenic and changes in mineral phases of arsenic and iron. The observed solubilization of arsenic was decoupled from iron reduction in the site-oxidized sediments in the presence of native organic carbon, which disagreed with the widely accepted hypothesis that arsenic solubilization is derived from microbial driven reductive dissolution of iron oxides. Carbonate minerals were defined as the mineral phase associated with arsenic that contributed to the arsenic measured in solution.
The second objective was to determine how altering redox and water conditions down a profile affects arsenic geochemistry and hence solubility. Redox stratification was delineated in two sediment cores based on chemical analyses and visual observation of redox-sensitive parameters. The vadose zone released a considerable amount of arsenic, while the next zone, the carbonate enrichment zone, released the highest concentration of arsenic. Soluble arsenic was exclusively As(V) in the redox transition zone, where As was primarily associated with iron oxides. Solubilization of arsenic was limited in the deeply reduced depletion zone due to the formation of sulfide minerals.
Lateral resolution of oxidation state and elemental association of arsenic at the micron scale were delineated using synchrotron-based X-ray absorption spectroscopy under Objective 3. The presence of unaltered arsenic sulfides was revealed in the vadose zone, suggesting that arsenic was inputted continuously to the ground surface. From the water table to the deeply reduced depletion zone sediments, arsenic mineral association was dominated by manganese-bearing carbonate minerals and amorphous iron oxides, which are vulnerable to groundwater fluctuation and redox-cycling.

description: Corporate governance experts pay considerable attention to the composition of the full board of directors. And yet, much of the substantive work of the board is carried out by committee. While the nominating and governance committee, in consultation with the chairman or lead independent director, are responsible for recommending committee assignments, there is some degree of opacity to the process. In particular, it is not clear what consideration they give to the distribution of knowledge and workload across committee appointments. We examine this issue in greater detail, and ask: How exactly do companies decide which directors to assign to each committee? Do they intentionally create overlaps across committees to facilitate knowledge sharing, or do overlaps occur randomly? Do leaders of the board monitor the “busyness” of individual directors? How can the board ensure that the benefits of information sharing are not outweighed by excessive workload?
Non-thermal radiation from molecular clouds illuminated by cosmic rays from nearby supernova remnants

description: Molecular clouds are expected to emit non-thermal radiation due to cosmic ray interactions in the dense magnetized gas. Such emission is amplified if a cloud is located close to an accelerator of cosmic rays and if cosmic rays can leave the accelerator and diffusively reach the cloud. We consider the situation in which a molecular cloud is located in the proximity of a supernova remnant which is accelerating cosmic rays and gradually releasing them into the interstellar medium. We calculate the multiwavelength spectrum from radio to gamma rays which emerges from the cloud as the result of cosmic ray interactions. The total energy output is dominated by the gamma ray emission, which can exceed the emission from other bands by an order of magnitude or more. This suggests that some of the unidentified TeV sources detected so far, with no obvious or very weak counterpart in other wavelengths, might be associated with clouds illuminated by cosmic rays coming from a nearby source.

description: It is well known that isoperimetric inequalities imply in a very general measure-metric-space setting appropriate concentration inequalities. The former bound the boundary measure of sets as a function of their measure, whereas the latter bound the measure of sets separated from sets having half the total measure, as a function of their mutual distance. We show that under a lower bound condition on the Bakry--Émery curvature tensor of a Riemannian manifold equipped with a density, completely general concentration inequalities imply back their isoperimetric counterparts, up to dimension \emph{independent} bounds. As a corollary, we can recover and extend all previously known (dimension dependent) results by generalizing an isoperimetric inequality of Bobkov, and provide a new proof that under natural convexity assumptions, arbitrarily weak concentration implies a dimension independent linear isoperimetric inequality. Further applications will be described in a subsequent work. Contrary to previous attempts in this direction, our method is entirely geometric, continuing the approach set forth by Gromov and adapted to the manifold-with-density setting by Morgan.

description: The ABJM model is a superconformal Chern-Simons theory with N=6 supersymmetry which is believed to be integrable in the planar limit. However, there is a coupling dependent function that appears in the magnon dispersion relation and the asymptotic Bethe ansatz that is only known to leading order at strong and weak coupling. We compute this function to four loops in perturbation theory by an explicit Feynman diagram calculation for both the ABJM model and the ABJ extension. We find that all coefficients have maximal transcendentality. We then compute the four-loop wrapping correction for a scalar operator in the 20 of SU(4) and find that it agrees with a recent prediction from the ABJM Y-system of Gromov, Kazakov and Vieira. We also propose a limit of the ABJ model that might be perturbatively integrable at all loop orders but has a short range Hamiltonian.

description: By appealing to renewal theory we determine the equations that the mean exit time of a continuous-time random walk with drift satisfies both when the present coincides with a jump instant or when it does not. Particular attention is paid to the corrections ensuing from the non-Markovian nature of the process. We show that when drift and jumps have the same sign the relevant integral equations can be solved in closed form. The case when holding times have the classical Erlang distribution is considered in detail.

title: Factors Influencing the Successful Regeneration of Aspen in Southern Utah, USA
Creators: name: Britton, Justin M.

description: There has been recent concern regarding the regeneration and recruitment of aspen (Populus tremuloides) in the western United States. Forest management techniques have been employed in order to promote the regeneration and recruitment of aspen. We quantified aspen regeneration treatments in southern Utah, USA to better understand the factors driving aspen recruitment. Driving factors were identified by addressing two major research themes: (1) identify the primary ecological controls on aspen regeneration success; (2) assess the relative importance and influence of these controls on successful regeneration. Our definition of successful aspen regeneration requires the satisfaction of two criteria relating to height and density, respectively: (1) regeneration that has attained heights above the ungulate browsing threshold (e.g. >2m); and (2) regeneration that is occurring at a density that represents desired conditions for future stocking (e.g. ≥10,000 stems ha⁻¹). The primary ecological controls on regeneration success were identified using nonmetric multidimensional scaling, and Random Forests analysis was used to assess the relative importance and influence of regeneration controls. These analyses identified three primary factors that are responsible for regeneration success. These factors were (1) contemporary herbivory pressure, (2) site preparation technique, and (3) advance reproduction. Herbivory is the leading predictor of regeneration success, and has integral impacts on other primary regeneration drivers. We suggest considerations that can be made regarding regeneration drivers in order to enhance the effectiveness of aspen management in the future.

description: Institutional investors are highly dissatisfied with the quality of information that they receive about corporate governance policies and practices in the annual proxy. Across the board, they want proxies to be shorter, more concise, more candid, and less legal. The largest complaint involves executive compensation and the inability of investors to determine whether senior management is paid appropriately. Based on recent survey data from major institutional investors, we describe the information that shareholders would like to see in the “ideal” proxy statement. We ask: What changes can companies make to proxies that contain the information that investors want in a format that is easy to read and navigate? Would shareholder understanding of corporate governance practices improve if companies provided clearer and more succinct data? How might the debate about executive compensation change?
title: Influence of Breed Type, Milk Production Potential and Cow Size Upon Maintenance Requirements

description: Two biological types of cows, straightbred Herefords (HxH) and Simmental-Hereford crosses (SxH), of similar body condition were individually fed over a 10 week period to compare the biological types for maintenance and to determine the influence of milk production potential and of size. Cows were nonlactating and in the last part of the first trimester of pregnancy. During the first 5 weeks of the feeding experiment, one-half of each type was fed 75% of estimated maintenance while the other half was fed 125% of estimated maintenance. During the last 5 weeks of the experiment those fed at 75% of maintenance in the first 5 weeks were now fed 140% of maintenance while those fed 125% of maintenance in the first 5 weeks were now fed 65% of maintenance.
Maintenance requirement was estimated by two methods. The first method, regression of gain or loss on energy intake, showed a higher, but non-significant maintenance requirement for SxH (137.5 vs. 128.3 kcal ME/kg.75/day for SxH and HxH, respectively).
The second method, which involved estimating maintenance as the residual when energy associated with gain or loss in weight was subtracted or added to the total energy intake, gave maintenance values of 117.6 and 145.9 kcal ME/kg.75/day for HxH and SxH cows, respectively.
A comparison of gain in weight for amount of energy consumed, for cows having equal energy intake per unit of metabolic size, indicated that HxH cows used energy more efficiently than SxH cows (P
