Crop Stress Detection and Classification Using Hyperspectral Remote Sensing

Agricultural production has observed many changes in technology over the last 20 years. Producers are able to utilize technologies such as site-specific applicators and remotely sensed data to assist with decision making for best management practices which can improve crop production and provide protection to the environment. It is known that plant stress can interfere with photosynthetic reactions within the plant and/or the physical structure of the plant. Common types of stress associated with agricultural crops include herbicide induced stress, nutrient stress, and drought stress from lack of water. Herbicide induced crop stress is not a new problem. However, with increased acreage being planting in varieties/hybrids that contain herbicide resistant traits, herbicide injury to non-target crops will continue to be problematic for producers. With rapid adoption of herbicide-tolerant cropping systems, it is likely that herbicide induced stress will continue to be a major concern. To date, commercially available herbicide-tolerant varieties/hybrids contain traits which allow herbicides like glyphosate and glufosinate-ammonium to be applied as a broadcast application during the growing season. Both glyphosate and glufosinate-ammonium are broad spectrum herbicides which have activity on a large number of plant species, including major crops like non-transgenic soybean, corn, and cotton. Therefore, it is possible for crop stress from herbicide applications to occur in neighboring fields that contain susceptible crop varieties/hybrids. Nutrient and moisture stress as well as stress caused by herbicide applications can interact to influence yields in agricultural fields. If remotely sensed data can be used to accurately identify specific levels of crop stress, it is possible that producers can use this information to better assist them in crop management to maximize yields and protect their investments. This research was conducted to evaluate classification of specific crop stresses utilizing hyperspectral remote sensing

Professional Development Principles for Teachers of English Language Learners

Since effective professional development is logically embedded in the reality of schools and teachers‘ work, it stands to reason that the principal would consider that reality for teachers of English language learners (ELL). Certainly, in general, professional development would incorporate principles of adult learning as reported by Knowles (1980): (1) adult learners need to be self-directed; (2) they display readiness to learn when they have a perceived need; and (3) they desire immediate application of new skills and knowledge. Based on adult learning theory, then, principals would provide teachers of ELLs professional development that addresses a need for self-direction, that addresses their particular needs, and that addresses the desire to apply what is learned. Time and created situations whereby teachers can dialogue with other teachers and principals can dialogue with other principals is critical for the effective application of the knowledge gained in professional development sessions and afterward as well

The Synergistic Leadership Theory: Contextualizing Multiple Realities of Female Leaders

The authors describe the Synergistic Leadership Theory (SLT), which includes four factors: Leadership Behavior, Organizational Structure, External Factors, and Beliefs, Attitudes, and Values. The factors are described and contributions to existing leadership theory are explained. They further apply the factors to four cases in order to illustrate the application of the theory to leadership practice. The authors conclude that SLT, in including the female perspective, provides an expanded framework for taking a macro-perspective of the interactions among beliefs, external forces, people, and organizations

Foraging Behavior of American Redstarts in Breeding and Wintering Habitats: Implications for Relative Food Availability

We investigated food availability for a long-distance migrant species, the American Redstart (Setophaga ruticilla), in both its summer breeding habitat in New Hampshire and in its winter habitat in Jamaica. We used four components of foraging behavior (prey attack rate, foraging speed, time spent foraging, and foraging maneuver use) as indicators of the relative availability of prey in the two seasons. Redstarts attacked prey at a significantly greater rate in summer than in winter, indicating that foraging birds encountered prey more frequently in summer. The winter prey-encounter rate was low even though redstarts moved almost twice as fast while foraging in winter as in summer. Male redstarts also spent more time foraging in winter (85%) than in summer (43-65%), possibly to balance the low rate at which they encountered prey. In winter, redstarts used more foraging maneuvers that were directed towards small flying prey, whereas in summer they used maneuvers that resulted in the capture of relatively large and presumably energy-rich prey such as lepidopteran larvae. That wintering redstarts foraged faster, attacked prey less often, and spent more time foraging than those in summer indicates that the winter is a period of relative food scarcity for this species, whereas the breeding season is a period of greater resource abundance

Mentoring New Faculty on the Road to Tenure

One of the first mentoring steps is to help new faculty members determine how many articles can be published from their dissertations. We contend that any dissertation of seminal importance can produce multiple journal articles. For example, the literature review may be suitable for publication if it is a critique of the literature with major issues raised on the specific topic of interest. If the new faculty member did not conduct a critique of the literature, then that may be a suggestion; and as that is done, references can be updated as well. The dissertation may have resulted in a specific intervention that is worthy of a manuscript. In that manuscript, recommend to the mentee that the researched intervention should be described in detail and could be submitted to a journal related to the intervention. For example, it could have been a mathematics intervention that worked well in a secondary school program. Such a description may be helpful to secondary school administrators and could be shared via a journal supported by the Texas Association of Secondary School Principals. Such suggestions from the mentor constitute the beginning of a publication plan for tenure for the new faculty member
