The Lives of the Peripatetics: Diogenes Laertius, Vitae Philosophorum, Book Five

The fifth book of Diogenes Laertius’ Lives of the Philosophers is concerned with the first four heads of the Peripatos – Aristotle, Theophrastus, Strato, and Lyco – and two outstanding members of the school – Demetrius of Phalerum and Heraclides of Pontus. Consideration is given her to rather general matters of structure, organization, and arrangement of material in Book Five as a whole, to the different categories of information in the individual lives, and to the most striking feature of this book which set it apart from other books: namely, the wills of the first four scholarchs and the extensive catalogues of writings which Diogenes has included for five of the six philosophers

Mentoring Graduate Students for Academic Careers in Grassland Science

Effective mentorship enhances student productivity and career achievements, yet faculty generally do not receive mentorship training, nor does mentorship receive focused attention, evaluation, and recognition. The objectives of this paper are to 1) define mentorship and identify roles of a mentor, 2) highlight qualities and outcomes of effective mentoring, and 3) elaborate best mentoring practices, metrics for assessing mentoring, and challenges for mentoring the next generation of grassland scientists. Mentoring is a professional alliance where individuals work together to support the personal and professional growth, development, and success of the relational partners. Mentors should be altruistic discipline experts, have substantial mentorship training or experience, be accessible and giving of their time, and capable of identifying mentee strengths and weaknesses. Metrics of effective mentoring include being sought after by prospective mentees, providing mentor-mentee interaction leading to successful educational outcomes, mentees receiving awards and recognition while mastering critical career skills, developing a track record of mentee success in the job market and sustained mentee enthusiasm for their career, and finally, sustaining long-term personal and professional mentor-mentee engagement. Specific to training the next generation of academics in grassland science, there is need to maintain, or regain, a critical mass of grassland faculty who are trained mentors and capable of developing novel, creative, and impactful research questions. These combined skills attract funding and create exciting opportunities for mentees. By addressing important research questions, mentor-mentee teams advance grassland science, but importantly, they also serve end-users. When value is perceived by consumers of our science, it sets in motion a chain of events required to maintain a critical mass of grassland scientists and confirms the value and relevance of our discipline

A Study of the In-Service Education Program for Elementary Teachers of Rural Douglas County, Nebraska

Leaders in the professional and industrial fields recognize that the individuals they employ must continue to study and grow in their special fields. A doctor continues to study that he may keep up on recent developments in medicine. An expert mechanic must continually study new developments in modern machinery and the new models which are developed yearly. Bankers hold regular in-service courses to be able to meet new requests and follow new laws

Canopy Characteristics, Ingestive Behaviour and Herbage Intake in Cultivated Tropical Grasslands

Compared to temperate systems, there have been few detailed assessments of canopy characteristics and associated grazing behavior in planted tropical grasslands. Reasons include the large number of forage species used in warm climates, the diversity of their morphology, research priorities emphasizing germplasm evaluation and management, and limited resources. This review describes canopy attributes of C4 grass pastures, highlights the most important relationships between grazing behavior and these canopy characteristics, and discusses the implications of canopy characteristics and grazing behavior for long-term intake and animal performance. It is suggested that the largest differences in canopy characteristics between tropical and temperate swards are not total canopy measures but those of the upper canopy strata including leaf proportion and bulk density. This occurs because tropical swards, unlike many temperate ones, have large vertical heterogeneity in density, plant-part proportion and nutritive value. In temperate swards, bite weight is primarily a function of sward height, but leaf percentage, leaf mass, or green herbage mass of the upper strata of the canopy usually are more important with C4 grasses. The manner in which leaf is presented to the animal and the degree to which it can be prehended separate from stem and dead material of low digestibility are also of great significance in pastures based on C4 grasses

\u3ci\u3eAeschynomene\u3c/i\u3e and \u3ci\u3eCarpon Desmodium\u3c/i\u3e: Legumes for Bahiagrass Pasture in Florida

Soils and climate are very diverse across Florida, and no single legume has state-wide adaptation. However, aeschynomene (Aeschynomene americana), an annual, and carpon desmodium (Desmodium heterocarpon) cv. Florida, a perennial, are the most commonly used legumes for grazing on the central and southern peninsula, which produces 65% of Florida\u27s beef calves. Both grow well with bahiagrass (Paspalum notatum), which is the main pasture grass, with ~1M ha state-wide. Circa 65K ha of bahiagrass contain at least limited quantities of aeschynomene and 14K ha contain carpon desmodium

Climate Change and Legume Performance in Grassland Agroecosystems

We reviewed the literature to assess the effect of climate change factors on forage legumes. Whether growing in monoculture or mixtures with grasses, exposing legumes to elevated CO2 (eCO2) generally leads to sustained increases in forage accumulation (FA) and N fixation, but elevated temperature (eT) in conjunction with eCO2 usually reduces magnitude of these responses. In legumes, nodules represent large C sinks, precluding photosynthetic acclimation to eCO2 observed in non-N fixing plants. Greater N fixation in legume-grass mixtures exposed to eCO2 is due to greater percentage of legume N derived from symbiotic fixation and often an increase in legume proportion in mixtures. Herbage nutritive value (NV) responses to eCO2 are less pronounced than FA, but lesser herbage N and greater non-structural carbohydrate (NSC) concentrations are common with eCO2. Drought effects on legume NV are inconsistent, but eT usually decreases NV. Data from one legume species suggest eCO2 and eT negatively affect pollen grain morphology and viability, but they increase flower number and nectar sugar concentration. Under eT, flowers opened earlier in the day causing earlier pollinator visits, but when combined with water stress, eT reduced pollinator visits. Though there is variation in the literature for some responses, we conclude that eCO2 generally increases legume FA, N fixation, and tissue NSC concentration, while reducing herbage N concentration. Drought reduces FA, but drought effects on NV are not consistent. Elevated temperature has a negative effect on legume NV, and, when combined with eCO2, can reduce the magnitude of the positive FA and N fixation response to eCO2. Climate change factors can affect legume pollen viability and pollinator behavior, potentially influencing plant reproductive success. Overall, effects of climate change factors on forage legumes can be generalized, but interactions among change factors and site-specific soil and climate conditions may cause variation from expected responses

DataScope: Predictive Diagnosis in IIoT-enabled Smart Manufacturing

This a collaborative project between Elizabethtown College and CPNet, LLC that is looking to help apply predictive modeling with CPNet’s domain knowledge to one of CPNet’s clients\u27 IIoT manufacturing problems. CPNet has provided us with datasets taken from one of their clients in the hope that we can build a model that will be able to predict when a part within the machines they are looking at will fail and subsequently shut the machine down. We are trying to take their data and turn it into information that the company can take preemptive action on and save them downtime during operation. In this project, we designed a health index that we used to create y-labels that we did not have in our dataset. We did this so that we could solve the remaining useful life problem of our project, which is where we attempt to determine how long the machine has to run before a failure or maintenance is needed based off of the health index using machine learning. We then went on to build several machine learning models to solve our problem. First, we used traditional machine learning models such as Polynomial Regression, Tree-based Regression, Ridge, Regression and XGBoost. Later we turned to Neural Networks and built a Multilayer Perceptron, a Convolutional Neural Network and a Recurrent Neural Network. From our experiments traditional machine learning models outperformed the neural networks. This was to be expected since the dataset wasn’t that large, but it was worth testing regardless. Also, from our experiments it is apparent that a part of our health index the CPK (CPK analysis will be explained in greater detail later in the paper.) will need to be worked on in the future to provide better y-labels. All in all, this project did show that this problem is worth exploring in the future since the solution could be quite valuable in smart manufacturing

Looking inside ourselves: a culture of kindness

Looking inside ourselves—being present and attentive to our own and others’ words and feelings—helps us communicate and interact with a mindful, open heart. Mindfulness and patient-centeredness help caregivers provide higher quality care. Historical background on a predecessor of mindfulness—the biopsychosocial model of health and disease, developed at the University of Rochester—provides context for the mindfulness “movement” in health care. A culture of mindfulness, supported by mindfulness and meditation training for physicians and other health care providers, helps practitioners show greater compassion, kindness, and humanity, all qualities that patients need and deserve. In the health care world, many organizations have been created that focus on aspects of mindfulness. Some have a more clinical emphasis and others focus on behavioral or neuroscience research as it relates to meditation, mindfulness, compassion, and kindness. Mindfulness is also being taught in business schools and corporations. Leaders who approach their teams with respect, integrity, honesty, and kindness are more effective leaders. Organizations like Google, Nike, and Aetna, among others, use the concept of mindfulness, as well as emotional and social intelligence, to build interpersonal competencies and create more people-centered workplaces. As medical libraries live in the health care environment and medical library leaders are key to libraries’ present and future, there are strong reasons to address the concepts of mindfulness and kindness and put them to work in the medical library workplaces. A mindfulness meditation exercise closes the lecture, sending the attendees out into their day with calm and open minds and hearts. A transcript of the lecture and accompanying slides are available in the supplementary materials
