    A winter grazing experiment was conducted to evaluate the performance of bred 2-year old second-calf heifers grazing stockpiled forage at two stocking rates and two levels of supplementation during winter. Two 30- acre blocks containing \u27Fawn\u27 endophyte-free tall fescuered clover were each divided into four pastures of 6.25 or 8.75 acres. Hay was harvested from the pastures in June and August of 2003 and N applied at 40 lb/acre to initiate stockpiling in August. On October 22, 2003, twenty-four Angus-Simmental two-year old heifers, pregnant with their second calf, were allotted by weight and body condition score (BCS) to strip-graze for 147 d at 0.48 or 0.34 cow/acre and eight similar second-calf heifers were allotted to two drylots and fed tall fescue-red clover hay. Corn gluten feed was fed to maintain a mean BCS of 5 or 4.33 (9-point scale) for the high and low supplementation levels, respectively, or when weather prevented grazing. Mean initial forage yield was 3188 lb/acre and decreased 12.2 lb/acre/d in grazed areas of the pasture over 147 d. Mean seasonal concentrations of CP and IVDMD were greater (P \u3c 0.05) in hay than stockpiled forage, while the concentration of ADF was greater (P \u3c 0.05) in stockpiled forage. At the conclusion of winter feeding, animals grazing at the low stocking rate had greater (P \u3c 0.1) BW than those grazing at the high stocking rate, and the BCS of grazing animals was 0.42 lower (P \u3c 0.05) than animals maintained in the drylot. Animals in the drylot were fed 5944 lb/hd of hay. Mean amounts of corn gluten feed fed was 189.6, 19.1, 278.5, 16.9, and 5.2 lb DM/hd for the high stocking rate-high supplementation, high stocking rate-low supplementation, low stocking rate-high supplementation, low stocking rate-low supplementation, and drylot treatments, respectively, but did not significantly differ (P \u3e 0.1)

    A Summary of Monthly Nutrient Values for Stockpiled Forages in Iowa State University Research Studies

    Get PDF
    It appears from this summary of previous Iowa State University research results that protein and energy levels in forages stockpiled starting in August will for the most part have sufficient protein and energy to maintain a beef cow during the middle and last part of their pregnancy. Tall fescue-alfalfa stockpiled forage had two months that would not meet protein and energy requirements, but it is important to realize that selective grazing in that forage type would likely overcome those deficiencies. However, it is important to realize that sufficient forage accumulation is imperative to meeting the total nutrient demand of the beef cow

    A Summary of Monthly Nutrient Values for Research Pastures in the Growing Months

    Get PDF
    This analysis shows that research pastures contain sufficient protein and in most months energy to maintain a beef cow during the lactation phase of the yearly beef production cycle. Crude protein in comparison to the needs of a 1400 pound lactating beef range from 113 percent to 220 percent of the requirement. Energy in comparison to the same need ranged from 87 percent to 118 percent. Eleven of 36 months evaluated were below energy needs. However, previous research has demonstrated that cattle will have selected forage intake that is 3 percent higher in digestible dry matter

    Retelling racialized violence, remaking white innocence: the politics of interlocking oppressions in transgender day of remembrance

    Get PDF
    Transgender Day of Remembrance has become a significant political event among those resisting violence against gender-variant persons. Commemorated in more than 250 locations worldwide, this day honors individuals who were killed due to anti-transgender hatred or prejudice. However, by focusing on transphobia as the definitive cause of violence, this ritual potentially obscures the ways in which hierarchies of race, class, and sexuality constitute such acts. Taking the Transgender Day of Remembrance/Remembering Our Dead project as a case study for considering the politics of memorialization, as well as tracing the narrative history of the Fred F. C. Martinez murder case in Colorado, the author argues that deracialized accounts of violence produce seemingly innocent White witnesses who can consume these spectacles of domination without confronting their own complicity in such acts. The author suggests that remembrance practices require critical rethinking if we are to confront violence in more effective ways.

    Critical Language and Discourse Awareness in Management Education

    Get PDF
    Communication and, through it, language have become key elements of business and organizational life. How organizations interact within their walls and with the outside world fundamentally affects business processes, creating organizational culture, shaping public perceptions, and influencing consumer choices. This essay calls for a greater acknowledgment of language and communication and suggests that management educators may want to review how they are incorporated in management education curricula. Expanding on the skill-based approach typically adopted in business school classes, the essay points to the utility of exposing business students to the dual function of language as a means of doing work and as a social action that constitutes social reality. Drawing on examples from scholarship in linguistics and discourse analysis, the essay demonstrates that the ability to notice, identify, and reflect on linguistic and discourse practices is a crucial managerial skill. Nurturing such analytical and thinking skills enables people to become not only better communicators but also critical thinkers able to understand and challenge when social control, power, or injustice is enacted in organizations

    Managerial delegation in a dynamic renewable resource oligopoly

    Get PDF
    I propose a differential oligopoly game of resource extraction under (quasi-static) open-loop and nonlinear feedback strategies, where firms are managerial and two alternative types of delegation contract are considered. Under open-loop information, delegation expands the residual steady state resource stock. Conversely, under nonlinear feedback information the outcome depends on the structure of managerial incentives. If sales are used, once again delegation favours resource preservation. On the contrary, if market shares are included in the delegation contract, this combines with an underlying voracity effect in shrinking the steady state volume of the resource

    Gendered representations in Hawai‘i’s anti-GMO activism

    Get PDF
    The aim of this article is to analyse some of the representations of intersectional gender that materialise in activism against genetically modified organisms (GMOs). It uses the case of Hawai‘i as a key node in global transgenic seed production and hotspot for food, land and farming controversies. Based on ethnographic work conducted since 2012, the article suggests some of the ways that gender is represented within movements against GMOs by analysing activist media representations. The article shows how gender, understood intersectionally, informs possibilities for movement-identification, exploring how themes of motherhood, warrior masculinities and sexualised femininities are represented within these movements. The article suggests that some activist representations of gender invoke what could be considered as normative framings of gender similar to those seen in other environmental, food and anti-GMO movements. It is suggested that these gendered representations may influence and limit how different subjects engage with Hawai'i anti-GMO movements. At the same time, contextual, intersectional readings demonstrate the complex histories behind what appear to be gender normative activist representations. Taken together, this emphasis on relative norms of femininities and masculinities may provide anti-GMO organising with familiar social frames that counterbalance otherwise threatening campaigns against (agri)business in the settler state. Understood within these histories, the work that gender does within anti-GMO organising may offer generative examples for thinking through the relationships between gendered representations and situated, indigenous-centred, food and land-based resistances
