    Feed formulation to meet nutritional requirements of livestock is becoming increasingly challenging. Regulations have banned the use of traditional high-quality protein supplements such as meat-and-bone meal, pollution from animal excreta of N and P is an issue and antibiotics are no longer available as insurance against the impact of enteric infection and feed anti-nutritional factors. The improved genetic potential of livestock is increasing daily requirement for energy and protein (essential amino acids). To benefit from the enhanced growth potential of livestock diets with high nutrient density are needed that can be formulated from crops without increased cost. Genetic modification of commodity crops used to manufacture animal feed in order to improve the density and quality of available nutrients is a potential solution to some of these problems. Furthermore, crops may be used as biofactories to produce molecules and products used in animal feed with considerable reductions in manufacturing fixed costs. Nevertheless, there are considerable not insurmountable challenges, such as the creation of sufficient economic value to deliver benefit to all members in the feed production chain, which is an essential element of identity preserving and delivering the technology to livestock producers. Individual output traits in the major commodity crops may not provide sufficient value to adequately compensate all the members of the feed production chain. Successful adoption of output traits may rely on inserting combinations of agronomic input traits with specific quality traits or increasing the value proposition by inserting combinations of output trait

    The purpose of this study was to explore faculty views on the inclusion of spiritual topics in graduate leadership and management programs, focusing on faculty experiences, perceived benefits and challenges, and teaching methods and principles in use. We interviewed twelve faculty members in leadership or management programs from eleven nonsectarian universities. Participants discussed eight benefits including the opportunity for whole person growth and skill development that would benefit leaders in a global workplace. Eight barriers to such inclusion were identified such as proselytizing and the misuse of power. The sampled instructors also made some suggestions for how to include spirituality topics, such as using respected resources and linking classroom discussions to practice. Overall, instructors’ preference for including spiritual topics also varied in terms of explicit versus implicit and organic-emergent versus preplanned-structured approaches

    Creating a Faith-Friendly School Culture in Religiously Plural Communities: A Neglected Facet of Diversity

    Get PDF
    School leaders serve religiously diverse communities, engaging with staff and parents from many backgrounds to address the academic and development needs of all children. While educator preparation often includes some instruction in cultural competence, religious diversity gets little attention. The purpose of this conceptual article is to provide guidance for school leaders to create a workplace and school culture hospitable to employees from all religious, spiritual, and non-religious backgrounds. Using Miller and Ewest’s (2015) Faith and Work Organizational framework, this article reviews findings from the management literature on workplace spirituality including the sparse empirical literature on religious expression in the school (as a workplace) and from case law on employment-related religious expression in schools. We synthesize the concepts and findings into actionable recommendations for school leaders to guide them towards creating inclusive, religiously plural, faith-safe or faith-friendly workplaces where educators can flourish and thrive. Recommendations include a policy review, adoption of norms of respectful pluralism, and religious literacy training

    Abrasive Leaders Who Changed: Learning From Their Experience

    Get PDF
    The purpose of this paper is to understand the experience of three formerly abrasive leaders who improved their conduct and management strategies following a workplace intervention. Narrative inquiry, a personal and collaborative research method, revealed the experience of three leaders in their shift from destructive behaviors. Concepts from adult development, specifically Kegan\u27s constructive-development theory (CDT) and Mezirow\u27s transformative learning theory (TL), provided a lens to better understand the leaders\u27 personal development. This study culminated with three co-composed narrative accounts and an analysis of narrative threads. The focus of this paper is the interpretive narrative thread analysis. The developmental experience of these three leaders included disruption, awakening and equipping. This study included three leaders. The experience of these leaders may not be representative of other formerly abrasive leaders. This initial exploratory study contributes to CDT and TL by suggesting leader interpersonal development is an intensely emotional experience that transcends the mechanics of developmental stages. In practice, this study indicates abrasive leaders may improve their conduct and management strategies with organizational support, including supervisor intervention and specialized professionals. This paper offers insight for scholars and human resource (HR) professionals on the emotionally intense experiential journey of leaders who improved their interpersonal conduct. This study introduces concepts from CDT and TL into the study of workplace psychological aggression (WPA), and it expands the limited knowledge of how HR can support positive perpetrator change

    Late Light Curves of Normal Type Ia Supernovae

    We present late-epoch optical photometry (BVRI) of seven normal/super-luminous Type Ia supernovae: SN 2000E, SN 2000ce, SN 2000cx, SN 2001C, SN 2001V, SN 2001bg, SN 2001dp. The photometry of these objects was obtained using a template subtraction method to eliminate galaxy light contamination during aperture photometry. We show the optical light curves of these supernovae out to epochs of up to ~640 days after the explosion of the supernova. We show a linear decline in these data during the epoch of 200-500 days after explosion with the decline rate in the B,V,& R bands equal to about 1.4 mag/100 days, but the decline rate of the I-band is much shallower at 0.94 mag/100 days.Comment: 33 pages, 11 figures, Accepted for publication in The Astronomical Journa

    Time-Series Analysis of Supergranule Characterstics at Solar Minimum

    Get PDF
    Sixty days of Doppler images from the Solar and Heliospheric Observatory (SOHO) / Michelson Doppler Imager (MDI) investigation during the 1996 and 2008 solar minima have been analyzed to show that certain supergranule characteristics (size, size range, and horizontal velocity) exhibit fluctuations of three to five days. Cross-correlating parameters showed a good, positive correlation between supergranulation size and size range, and a moderate, negative correlation between size range and velocity. The size and velocity do exhibit a moderate, negative correlation, but with a small time lag (less than 12 hours). Supergranule sizes during five days of co-temporal data from MDI and the Solar Dynamics Observatory (SDO) / Helioseismic Magnetic Imager (HMI) exhibit similar fluctuations with a high level of correlation between them. This verifies the solar origin of the fluctuations, which cannot be caused by instrumental artifacts according to these observations. Similar fluctuations are also observed in data simulations that model the evolution of the MDI Doppler pattern over a 60-day period. Correlations between the supergranule size and size range time-series derived from the simulated data are similar to those seen in MDI data. A simple toy-model using cumulative, uncorrelated exponential growth and decay patterns at random emergence times produces a time-series similar to the data simulations. The qualitative similarities between the simulated and the observed time-series suggest that the fluctuations arise from stochastic processes occurring within the solar convection zone. This behavior, propagating to surface manifestations of supergranulation, may assist our understanding of magnetic-field-line advection, evolution, and interaction

    Properties of Supergranulation During the Solar Minima of Cycles 22/23 and 23/24

    The solar minimum at the transition from cycle 23 to 24 was notable for its low level of activity and its extended duration. Among the various fields of study, the evolution of the solar convection zone may provide insight into the causes and consequences of this recent minimum. This study continues previous investigations of the characteristics of solar supergranulation, a convection component strongly linked to the structure of the magnetic field, namely the time-evolution of the global mean of supergranule cell size, determined from spectral analysis of MDI Dopplergrams from the two previous solar minima. Analyses of the global mean of supergranule sizes show a quasi-oscillatory nature to the evolution of this particular supergranule characteristic. Performing similar analyses on realistic, synthetic Doppler images show similar time-dependent characteristics. We conclude that the observed fluctuations are not observational artifacts, and that an underlying trend exists within the evolution of the supergranulation network
