Developing Understandings of Collaborative Partnerships Between University and Community

University faculty define collaborative partnerships with the community and examine how collaborative partnerships engender community-based research and the learning process of students in the College of Public Service. Considerations include how students are acculturated, specific benefits to learning, unanticipated benefits, and the unexpected challenges of collaborative partnerships between a university and a community

Big Read: Collaborations Between a University and a Community

University and community partners write about their collaborations around the reading of Ernest Gaines’ A Lesson Before Dying. When an urban university received a National Endowment of the Arts Big Read Grant, they immediately began making connections to existing key initiatives within the university and in the surrounding community. As the partners collaborated within and among the university and community programs and events created for the Big Read they made multiple discoveries regarding the importance of planning together, analyzing the intended audience for each program and event, including multiple ways to access the text, and considering the ways that readers can personalize the issues, synthesize what they have learned and apply it in discussion or action

Binocular coordination of eye movements – Hering’s Law of equal innervation or uniocular control?

The neurophysiological basis for binocular control of eye movements in primates has been characterized by a scientific controversy that has its origin in the historical conflict of Hering and Helmholtz in the 19th century. This review focuses on two hypotheses, linked to that conflict, that seek to account for binocular coordination – Hering’s Law vs. uniocular control of each eye. In an effort to manage the length of the review, the focus is on extracellular single‐unit studies of premotor eye movement cells and extraocular motoneurons. In the latter half of the 20th century, these studies provided a wealth of neurophysiological data pertaining to the control of vergence and conjugate eye movements. The data were initially supportive of Hering’s Law. More recent data, however, have provided support for uniocular control of each eye consistent with Helmholtz’s original idea. The controversy is far from resolved. New anatomical descriptions of the disparate inputs to multiply and singly innervated extraocular muscle fibers challenge the concept of a ‘final common pathway’ as they suggest there may be separate groups of motoneurons involved in vergence and conjugate control of eye position. These data provide a new challenge for interpretation of uniocular premotor control networks and how they cooperate to produce coordinated eye movements.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/86996/1/j.1460-9568.2011.07695.x.pd

Behavioural Significance of Cerebellar Modules

A key organisational feature of the cerebellum is its division into a series of cerebellar modules. Each module is defined by its climbing input originating from a well-defined region of the inferior olive, which targets one or more longitudinal zones of Purkinje cells within the cerebellar cortex. In turn, Purkinje cells within each zone project to specific regions of the cerebellar and vestibular nuclei. While much is known about the neuronal wiring of individual cerebellar modules, their behavioural significance remains poorly understood. Here, we briefly review some recent data on the functional role of three different cerebellar modules: the vermal A module, the paravermal C2 module and the lateral D2 module. The available evidence suggests that these modules have some differences in function: the A module is concerned with balance and the postural base for voluntary movements, the C2 module is concerned more with limb control and the D2 module is involved in predicting target motion in visually guided movements. However, these are not likely to be the only functions of these modules and the A and C2 modules are also both concerned with eye and head movements, suggesting that individual cerebellar modules do not necessarily have distinct functions in motor control

Aphids influence soil fungal communities in conventional agricultural systems

Arbuscular mycorrhizal fungi (AMF) form symbioses with the roots of most plant species, including cereals. AMF can increase the uptake of nutrients including nitrogen (N) and phosphorus (P), and of silicon (Si) as well as increase host resistance to various stresses. Plants can simultaneously interact with above-ground insect herbivores such as aphids, which can alter the proportion of plant roots colonized by AMF. However, it is unknown if aphids impact the structure of AMF communities colonizing plants or the extent of the extraradical mycelium produced in the soil, both of which can influence the defensive and nutritional benefit a plant derives from the symbiosis. This study investigated the effect of aphids on the plant-AMF interaction in a conventionally managed agricultural system. As plants also interact with other soil fungi, the non-AMF fungal community was also investigated. We hypothesized that aphids would depress plant growth, and reduce intraradical AMF colonization, soil fungal hyphal density and the diversity of AM and non-AM fungal communities. To test the effects of aphids, field plots of barley enclosed with insect proof cages were inoculated with Sitobion avenae or remained uninoculated. AMF specific and total fungal amplicon sequencing assessed root fungal communities 46 days after aphid addition. Aphids did not impact above-ground plant biomass, but did increase the grain N:P ratio. Whilst aphid presence had no impact on AMF intraradical colonization, soil fungal hyphal length density, or AMF community characteristics, there was a trend for the aphid treatment to increase vesicle numbers and the relative abundance of the AMF family Gigasporaceae. Contrary to expectations, the aphid treatment also increased the evenness of the total fungal community. This suggests that aphids can influence soil communities in conventional arable systems, a result that could have implications for multitrophic feedback loops between crop pests and soil organisms across the above-below-ground interface

Expectancy violations of the division of labor on marital satisfaction across the transition to parenthood

The current longitudinal study examines the effect of violated expectations related to the division of household and child-care labor on marital satisfaction across the transition to parenthood. The moderating effects of gender ideology on the relationship between violated expectations related to the division of child-care labor and marital satisfaction are also explored. Twenty-five married women completed questionnaires during their third trimester of pregnancy and again approximately three years after the birth of their first child. To determine if there was a significant decline in wives’ marital satisfaction following the transition to parenthood, a t-test was conducted comparing means for prenatal and postpartum reports of marital satisfaction. Hierarchical regression was used to test the remaining hypotheses regarding the effects of violated expectations of the postpartum division of household and child care labor (predictor variables) and gender ideology (moderator variable) on marital satisfaction (criterion variable). Collective and main effects were examined. As expected, results indicated a significant decline in marital satisfaction following the transition to parenthood. The results of this study also indicate that this decline may be predicted by deviations from prenatal expectations in regards to the division of child-care, but not household, labor. Lastly, this study did not find gender ideology to be a significant moderating variable on the relationship between deviations from expectations in relation to child-care labor and marital satisfaction. Clinical implications and recommendations for future research are discussed
