‘Will you be my mentor?’ Feminist mentoring at mid-career for institutional change

Abstract

This collaborative paper written by mid-career and senior faculty employed in public and private institutions explores the challenges of feminist mentoring at mid-career. We engage this problematic using dialogical writing as a means to highlight our experiences and needs for mentoring, while simultaneously co-mentoring one another to protect each other from cynicism and despair. Placing these experiences and dialogues in conversation with the existing literature on mentoring, we address the ways that mentoring can both reproduce and transform the neoliberal university, while simultaneously exploring the tensions these possibilities produce in the context of mid-career feminist mentoring. We discuss particular challenges associated with mid-career mentoring, focusing primarily on our roles as feminist, anti-racist mentors to non-traditional students and junior faculty. While recognizing that there is no clear solution to the challenges of feminist mentoring and institutional change, we examine various models of mentoring, highlighting both the potential and limitations of informal mentoring in producing institutional change. Our intention is that this dialogical piece of writing allows us to support each other as we share our own reflections, while offering mentoring advice for colleagues at different career stages. While mentoring can open up the possibility for minor disruptions and is an essential coping mechanism, it is just one small part of the struggle to challenge the structural inequality of the academy.     

Sinus and meningeal vessel pattern changes induced by artificial cranial deformation: A pilot study

This study explores the changes in sinus and meningeal vessel patterns caused by various types of artificial cranial deformation. Endocranial casts were prepared from six crania exhibiting one of three types of deformation (lambdoid, parallelo-fronto-occipital and fronto-vertico-occipital), as well as from 15 undeformed crania. Vessel and sulcus patterns of each cranium were analysed and these patterns included depth of impressions, size and number of vessels, and directional pathways of vessels. Comparisons were made within and between the different deformation types. The results indicated that deformation has an effect upon the pattern, shape and depth of vessel impressions. Vessels tended to be flattened in the areas directly affected by cranial deformation, and there was often compensatory enlargement of other vessels. Further, three of the six artificially deformed crania exhibited enlarged occipital/marginal sinuses, suggesting that this trait is developmentally plastic and greatly influenced by environmental factors.     

Daily rates of dentine formation in macaque tooth roots

When tetracycline antibiotics are administered either orally or by injection they bind at the forming mineral front of the dentine and become incorporated into teeth as a permanent label. In this study, oxytetracycline was used as a label in order to investigate the growth of root dentine in macaques. There are no good data available in the literature for daily rates of root dentine formation over a prolonged period of time in either humans or macaques. Records of ten doses of oxytetracycline administered orally at irregular intervals (but at the same time of day) over a period of 10 months to a young rhesus macaque monkey (Macaca mulatta) were used to calculate the rate of dentine formation in tooth roots. Rates of dentine formation in the first portion of third permanent molar root formation, and in the apical portion of permanent canine and premolar root formation, were consistently between 3 μm and 4 μm per day. There was no evidence in this study of a gradual decrease in daily dentine formation rate from the crown to the root, or along the length of a dentine tubule through the bulk of the dentine, as has been implied previously. With the exception of faster rates recorded in cusps or slower rates recorded at the very beginning or very end of primary dentine secretion in other studies, the results of the present study suggest a consistent rate of dentine formation in permanent macaque teeth. What data there are for human dentine formation rates suggests that it is likely this finding can be extended to human dentine as well.
