The science of botany is often daunting to people who are training to become Master Gardener volunteers. However, the range of natural diversity of plants as well as practical information about plant anatomy are essential foundations for other parts of Master Gardener training. I will present a botany module that I have developed over the past 5 years. The module focuses on relevance to the trainee and builds on basic information to examine more complex aspects of botany, all in the space of the 3–6 hours often allotted for basic botany training. It begins with a “tour” of the plant kingdom and plant relatives like algae and fungi, mosses, liverworts, and ferns. I follow this with basic morphology of stems, roots, and leaves; this basic morphology is used to answer the question of how water and minerals move from the soil into and throughout plants, even reaching the height of the tallest tree. A short segment on mycorhizzae reinforces water and mineral transport, while providing a link to the plant kingdom tour. The mycorhizzal section also reinforces or complements training on soils, which is often presented in another portion of the training schedule. Finally, a segment on flowers introduces basic terminology and winds up a discussion of how to recognize monocotyledons and dicotyledons. Several optional hands-on activities help active learners assimilate the information and provide needed reflective time for more traditional learners. The module has been adopted as the official OSU Extension Master Gardener™ Program botany module in Oregon.

Practical Implications

Purpose This paper aims to outline an emerging trend that is replacing traditional retirement; this trend is called “protirement.” Protirement is defined as early retirement from professional work with the positive idea of pursuing something more fulfilling and has originated from the “blend of pro- and retirement.” Design/methodology/approach This paper’s approach is to define the trend of protirement and then back the idea with data and cases of where and how this is implemented by human resources (HR) organizations. Findings Retirement, in its traditional sense, is becoming increasingly unattainable for individuals but is also less necessary than it has been in the past. People are living longer and healthier lives, and in fact, data show that working in some meaningful and valuable manner actually increases life-span and allows more time to save for the day when one cannot work anymore. Research limitations/implications The findings in this paper should spark others to do more research into the area of aging workforce and new models that will leverage senior workers for the benefit of individuals, organizations and society at large. Practical implications HR executives and their organizations will need to drive change in the areas of recruitment (senior workers), pension planning and saving and HR policies around retirement. Social implications People productivity has been in decline for over 10 years now. The authors are going to need all hands on deck to help fix this and overcome the economic challenges created by the 2020 pandemic. Leveraging senior workers brings deep expertise into the workplace that could be lost otherwise, improving productivity and organization learning. Originality/value This paper takes an idea coined in the 1960s and brings it into the 21st century, when and where it is really needed. This long-forgotten idea is being resurrected to help deal with today’s workplace challenges.

For the past five semesters, the Water Turbine Competition has added significant excitement and motivation to the historically dreaded Fluid Mechanics course offered in the Department of Civil and Mechanical Engineering at the United States Military Academy. The Water Turbine Competition is an adaptation of the national Hydropower Contest. Teams of two or three students build a water turbine that will lift a weight using only the potential energy stored in a tank of water that is suspended above ground level. The water turbine project has proven to be an exciting and beneficial educational tool.

Over the past decade, more women have become interested in renewable energy, particularly photovoltaics, but a suitable training environment is difficult to find. Approximately five years ago, Solar Energy International (SEI) started offering classes for women only. The premise is that a women only class provides a friendly atmosphere for women to ask basic questions, take time working with tools and concepts, and practice hands-on activities in a supportive environment. Sandia National Labs has assisted SEI by providing technical content and hands-on instruction. The classes are split between the classroom and the field. This paper will provide an overview of the technical training, safety and the importance of the National Electrical Code® (NEC)®, and accomplishments of the students beyond these classes.

As a result of the findings of scientists working on the biosynthesis and metabolism of steroids in the plant and animal kingdoms over the past five decades, it has become apparent that those compounds that naturally occur in animals can also be found as natural constituents of plants and vice versa, i.e., they have essentially the same fate in the majority of living organisms. This review summarizes the current state of knowledge on the occurrence of animal steroid hormones in the plant kingdom, particularly focusing on progesterone, testosterone, androstadienedione (boldione), androstenedione, and estrogens.

The Bologna Process

A summary of the personal investment in teaching fluid mechanics over 40 years in a French university is presented. Learning and Teaching Science and Engineering has never been easy, and in recent years it has become a crucial challenge for curriculum developers and teaching staff to offer attractive courses and optimized assessments. One objective is to ensure that students acquire competitive skills in higher science education that enable them to compete in the employment market, as the mechanical field is a privileged sector in industry. During the last decade, classical learning and teaching methods have been coupled with hands-on practice for future schoolteachers in a specific course on subjects including fluid mechanics. The hands-on/minds-on/hearts-on approach has demonstrated its effectiveness in training primary school teachers, and fluids are certainly a nice source of motivation for pupils in science learning. In mechanical engineering, for undergraduate and graduate students, the development of teaching material and the learning and teaching experience covers up to 40 years, mostly on fluid dynamics and related topics. Two periods are identified, those prior to and after the Bologna Process. Most recently, teaching instruction has focused on the Fluid Mechanics Concept Inventory (FMCI). This inventory has been recently introduced in France, with some modifications, and remedial tools have been developed and are proposed to students to remove misconceptions and misunderstandings of key concepts in fluid mechanics. The FMCI has yet to be tested in French higher education institutions, as are the innovative teaching methods that are emerging in fluid mechanics.

Over the past 50 years, the understanding of meiosis has aged like a fine bottle of wine: the complexity is developing but the wine itself is still young. While emphasis in the plant kingdom has been placed on the model diploids Arabidopsis (Arabidopsis thaliana L.) and rice (Orzya sativa L.), our research has mainly focussed on the polyploid, bread wheat (Triticum aestivum L.). Bread wheat is an important food source for nearly two-thirds of the world’s population. While creating new varieties can be achieved using existing or advanced breeding lines, we would also like to introduce beneficial traits from wild related species. However, expanding the use of non-adapted and wild germplasm in cereal breeding programs will depend on the ability to manipulate the cellular process of meiosis. Three important and tightly-regulated events that occur during early meiosis are chromosome pairing, synapsis and recombination. Which key genes control these events in meiosis (and how they do so) remains to be completely answered, particularly in crops such as wheat. Although the majority of published findings are from model organisms including yeast (Saccharomyces cerevisiae) and the nematode Caenorhabditis elegans, information from the plant kingdom has continued to grow in the past decade at a steady rate. It is with this new knowledge that we ask how meiosis will contribute to the future of cereal breeding. Indeed, how has it already shaped cereal breeding as we know it today?

New Ideas

For the past several years, i have sought out opportunities outside mathematics for personal enrichment and enjoyment. These experiences have caused me to become more aware of the connections between mathematics and other areas. As a result, I have begun developing lessons to show my students how mathematics is used in the real world. One summer I joined another teacher and twelve middle school students and decided to brave the eighteen-hour drive from Oklahoma to the Crow Canyon Archaeological Center in Co1tez, Colorado. The mathematical lesson discussed in this article emerged from one week of learning about the Anasazi culture and experiencing hands-on archaeology. Throughout the years, this lesson has been revised and expanded as both students and experience have given me new ideas.

Manned Space

Man's presence in space has proved to be an extremely valuable asset. During the past thirty years of manned space flight there have been numerous instances where man's ingenuity, fortitude, ability to deal with the unexpected, weigh risks, anticipate potential problems, and propose potential solutions have been largely responsible for the success of the mission. Nevertheless, the value of man in space is limited; for it is largely determined by how much he can produce; his productivity, in turn, is determined not only by the intrinsic abilities that he brings to the job, but also by the work environment provided him. In short, it is the intent of this paper to discuss some of the concepts and recommendations under consideration by the Columbus Program's Crew Activities Office for improving the productivity of the flight crews' work environment; where gains in productivity are defined in terms of increased crew efficiency, decreased crew error, and decreased crew training requirements. In doing so, this paper will address such areas as the flight crews' activity planning, their workstation design, and their on-board training. This paper will draw heavily from past space experiences, from Skylab, Shuttle Spacelab, and Solyut missions. The concepts and recommendations proposed are the result of: (1) direct hands-on experience from former NASA, ESA, and Russian astronauts; (2) a time and motion study of a past Spacelab mission (performed to better understand where and how crews spend their time); or (3) multiple crew workstation and neutral buoyancy simulations.
