Amherst, MA, United States

Hampshire College is a private liberal arts college in Amherst, Massachusetts, United States. It was opened in 1970 as an experiment in alternative education, in association with four other colleges in the Pioneer Valley: Amherst College, Smith College, Mount Holyoke College and the University of Massachusetts Amherst. Together they are now known as the Five Colleges, or the Five College Area.The College is widely known for its alternative curriculum, focus on portfolios rather than distribution requirements, and reliance on narrative evaluations instead of grades and GPAs. In some fields, it is among the top undergraduate institutions in percentage of graduates who enroll in graduate school. Fifty-six percent of its alumni have at least one graduate degree and it is ranked 30th among all US colleges in the percentage of its graduates who go on to attain a doctorate degree . Wikipedia.

Described as a blessing or a curse, a bonus or a bomb, the youthful population boom in the global South is thought to be the catalyst of present and future social change on a massive scale. These binary understandings of youth are popular among proponents of development programs aimed at young people, including for family planning. But dualistic, numbers-based theories oversimplify a much more complex picture. They narrow our perceptions of young populations and, when lacking more detailed understanding based in youth experience, have the potential to constrict sexual and reproductive health and rights. Instead, youth-friendly, inclusive sexual and reproductive health policy should build from young peoples' visions and diverse realities. © 2014 Reproductive Health Matters. Source

Pollen tubes usually exhibit a prominent region at their apex called the "clear zone" because it lacks light refracting amyloplasts. A robust, long clear zone often associates with fast growing pollen tubes, and thus serves as an indicator of pollen tube health. Nevertheless we do not understand how it arises or how it is maintained. Here we review the structure of the clear zone, and attempt to explain the factors that contribute to its formation. While amyloplasts and vacuolar elements are excluded from the clear zone, virtually all other organelles are present including secretory vesicles, mitochondria, Golgi dictyosomes, and the endoplasmic reticulum (ER). Secretory vesicles aggregate into an inverted cone appressed against the apical plasma membrane. ER elements move nearly to the extreme apex, whereas mitochondria and Golgi dictyosomes move less far forward. The cortical actin fringe assumes a central position in the control of clear zone formation and maintenance, given its role in generating cytoplasmic streaming. Other likely factors include the tip-focused calcium gradient, the apical pH gradient, the influx of water, and a host of signaling factors (small G-proteins). We think that the clear zone is an emergent property that depends on the interaction of several factors crucial for polarized growth. © 2014 Institute of Botany, Chinese Academy of Sciences. Source

This article provides a critical historical overview of the stress concept in bioarcheological research and critically evaluates the term "health" in reference to skeletal samples. Stress has a considerable history in 20th century physiological research, and the term has reached a critical capacity of meaning. Stress was operationalized around a series of generalized physiological responses that were associated with a deviation from homeostasis. The term was incorporated into anthropological research during the mid-20th century, and further defined in bioarcheological context around a series of skeletal indicators of physiological disruption and disease. Emphases on stress became a predominate area of research in bioarcheology, and eventually, many studies utilized the terms "health" and "stress" interchangeably as part of a broader, problem-oriented approach to evaluating prehistoric population dynamics. Use of the term "health" in relation to skeletal samples is associated with the intellectual history of bioarcheological research, specifically influences from cultural ecology and processualist archeology and remains problematic for two reasons. First, health represents a comprehensive state of wellbeing that includes physiological status and individual perception, factors that cannot be readily observed in skeletal samples. Second, the categorization of populations into relative levels of health represents a typological approach, however unintentional. This article advocates for the integration of methodological and theoretical advances from human biology and primatology, while simultaneously incorporating the theoretical constructs associated with social epidemiology into bioarcheological research. Such an approach will significantly increase the applicability of bioarcheological findings to anthropological and evolutionary research, and help realize the goal of a truly relevant bioarcheological paradigm.

The scale and importance of Vision and Change in Undergraduate Biology Education: A Call to Action challenges us to ask fundamental questions about widespread transformation of college biology instruction. I propose that we have clarified the "vision" but lack research-based models and evidence needed to guide the "change." To support this claim, I focus on several key topics, including evidence about effective use of active-teaching pedagogy by typical faculty and whether certain programs improve students' understanding of the Vision and Change core concepts. Program evaluation is especially problematic. While current education research and theory should inform evaluation, several prominent biology faculty-development programs continue to rely on self-reporting by faculty and students. Science, technology, engineering, and mathematics (STEM) faculty-development overviews can guide program design. Such studies highlight viewing faculty members as collaborators, embedding rewards faculty value, and characteristics of effective faculty-development learning communities. A recent National Research Council report on discipline-based STEM education research emphasizes the need for long-term faculty development and deep conceptual change in teaching and learning as the basis for genuine transformation of college instruction. Despite the progress evident in Vision and Change, forward momentum will likely be limited, because we lack evidence-based, reliable models for actually realizing the desired "change." © C. D'Avanzo.

The study of multimodal communication has become an active and vibrant field. This special issue of Behavioral Ecology and Sociobiology brings together new developments in this rapidly expanding area. In this final contribution to the special issue, I look to the future and discuss ten questions in need of further work, touching on issues ranging from theoretical modeling and the evolution of behavior to molecular mechanisms and the development of behavior. In particular, I emphasize that the use of multimodal communication allows animals to switch between sensory channels when one channel becomes too noisy, and suggest that a better understanding of this process may help us both to understand the evolution of multisensory signaling and to predict the success of species facing environmental changes that affect signaling channels, such as urbanization and climate change. An expanded section is included on the effects of climate change on animal communication across sensory channels, urging researchers to pursue this topic due to the rapidity with which the environment is currently transforming. © 2013 The Author(s).
