    Effects of No-Tillage on Crop Yields and Net Returns Across the United States

    Farmers are always looking for ways to increase yields and profits and no-tillage may be a way to achieve this goal. However, a comprehensive study of the performance of no-tillage yields relative to conventional tillage yields and their net returns is lacking. This study evaluated the potential factors that influence differences in conventional tillage and no-tillage yields and net returns as explained by such factors as time, crop, precipitation, soil texture and geographic region. Data were collected from 442 paired tillage experiments growing corn, soybeans, cotton, oats, wheat and sorghum published in three refereed journals. Data were evaluated using a mixed model and logit model respectively, to evaluate differences in mean yields and downside risk with no-tillage compared to tillage. Sorghum and wheat were found to have higher no-tillage yields relative to tillage. No-tillage was also found to outperform conventional tillage in the southern United States with just the opposite occurring in the northern U.S. A silty soil was also found to reduce no-tillage yields. Several factors were found to decrease the chance of downside risk with no-tillage, they were sorghum, sandy soil, Northern Crescent, Northern Great Plains, Prairie Gateway and Southern Seaboard regions. Two factors that increased the chance of lowered no-tillage yields were increased rainfall and length of use of no-tillage. Differences in mean net returns and downside risk were evaluated using a mixed model and logit model. Results showed that no-tillage was more profitable than conventional tillage in the Mississippi Portal region, but less profitable in the Prairie Gateway. Net returns were lower for no-tillage wheat and soybeans when produced in a clay soil. Cotton grown in sand had higher no-till net returns, but increased rainfall decreased cotton net returns. A logit model showed certain factors decreased the probability of lower no-tillage net returns. There was less downside risk with wheat grown under no-tillage as well as less downside risk in the Southern Seaboard region and when no-tillage was used on a clay soil. There were factors that increased the probability of lower no-tillage net returns; increased precipitation, Northern Great Plains, Prairie Gateway and Basin & Range regions

    Succession Planning for Next Generation Business Leaders

    The ability to backfill leadership positions has become a key focus of business leaders since 2005 when the baby boom workforce started to age. An aging workforce threatens the capability of business leaders to develop leadership pipelines to ensure business success. Grounded by the social exchange theory, the purpose of this qualitative single case study was to explore successful strategies that technology services managers used to align core business objectives to improve succession planning at a technology services organization located in Dallas, Texas. Data collection and triangulation included semi structured telephone interviews with 12 technology services managers, company documents, and archival information. Data analysis included the examination of rich text data, coding, and classification of themes using Yin\u27s 5-step approach. Four themes emerged, revealing that these managers (a) created and sustained a leadership talent pipeline for high potential employees for future leadership roles; (b) sourced internal candidates with core leadership competencies; (c) remediated leadership skills gaps through developed relationships and documented processes; and (d) re-engineered the replacement planning process for the internal leadership talent pipeline. Implications for positive social change include the potential for technology services managers to implement effective succession planning strategies that could increase employee morale, enhance profitability and growth, and promote healthy community partnerships

    Tracks Whitman\u27s previously unacknowledged influence on composer Claude Debussy and proposes that Debussy could not have avoided knowledge of Whitman had he tried, and his well-known nature aesthetic owes some--though by no means all--of its inspiration to that poet

    CRITICAL PERSPECTIVES ON BLACK FAMILY THEORY: A REVISED ABC-X MODEL FOR UNDERSTANDING BLACK FAMILY STRESS AND BLACK FAMILY STRENGTHS

    Get PDF
    Based on a study of Black corporate managers and their families it was discovered that existing models of family stress were incomplete, or inadequate in their ability to help us understand the nature of stress for these families and how that stress is managed, and, the coping resources available to these families with which to do so. Existing models are limited for Black families in that they do not take into account the pervasiveness of racism in the life experience of these families, nor do they include the traditional/historical strengths for survival of black families that can function as crisis meeting resources. An alternative conceptualization of McCubbin and Patterson’s (1981,1982,1983) Double ABCX Model, a revision of Reuben Hill’s (1965) ABCX Model, incorporating racism, and, the five traditional Black family strengths identified by Robert Hill (1971) is suggested. It is argued that the inclusion of racism in understanding the nexus of Black family stress and the traditional Black family strengths that enable Black families to cope with the stresses associated with work would be most useful. Discussion of differences by race and sources of stress with emphasis on Black families, and examples of the persistence of racism for Black corporate families will be provided. Discussion of the uses and value of traditional Black family strengths, including examples, will be given. Black corporate families are defined as a subset of Black upper middle to upper class families whose life experiences are similar to those of other Black same class families

    Frequently the women are required to assume the responsibility for meeting the clothing needs of members of the family. It is imp ortant to consider the clothing needs of the family as a unit which is of seperate elements, each determined in part by the activities of the individual members. Mothers must know the principles of color and design well enough to enable them to choose becomingly and attractive clothes for their children; they must know how clothing helps to maintain health and comfort; they must understand the economic basis for planning clothing budgets. The consideration of saving time and energy is especially essential when planning childrens\u27s clothes. When simplicity is the key-note of the entire wardrobe there is more time and more strength for other matters of importance. The purpose of this thesis is: to give definite information that will aid mothers is obtaining the greatest satisfaction from the money they spend for their children\u27s clothing

    Multigenerational Worship: Liturgical Dance and Mime within the African American Baptist Church

    Get PDF
    Historically, the African American Church has utilized movement to express personal faith. As attitudes towards movement changed, many churches limited or banned the use of dance in worship. Currently, many African American Baptist Churches have developed liturgical dance teams, providing a ministry for a variety of generations. These lyrical movements are danced to live or recorded music, usually contemporary Gospel music. Popularity of the liturgical dance teams has expanded to include mime, also known as Gospel mime. Many churches that worship in a multigenerational model provide relevant and transformational opportunities for all ages. Incorporating liturgical dance and mime as worship elements within worship has encouraged youth and young adults to be active participants in the worship experience. The Historic First Baptist Church (FBC) is an example of a traditional African American Baptist Church that has integrated liturgical dance and mime to the order of worship. Multiple generations are represented in worship; each generation possessing diverse characteristics and tendencies. In this qualitative historical study, FBC members representing the generations were surveyed to discover perceptions regarding the integration of liturgical dance and mime in worship. In addition, interviews of liturgical dance and mime ministry members and leaders discovered the preparation for ministry offerings, specifically through music choice, attire, choreography and facial expression. This research found that liturgical dance and gospel mime ministry offerings engage multigenerational worshipers
