While social identity challenges probably confront all school administrators, the authors focus on a doubly marginalized leadership population—Black female principals—whose experiences are rarely tapped. Based on lessons from this study and the literature reviewed, the authors think that leadership preparation programs should give prospective administrators opportunities to gain knowledge and develop skills relevant to navigating their leadership identities. In the age of accountability, and with the pressures placed on the education system to ensure the success of all students, school leaders are under constant scrutiny. The appearance, speech, body language, and interactions of principals with students, parents, teachers, and community members are dissected. Stretching to satisfy expectations, many principals find themselves trying to conform to a predefined image. Work pressures like these prove immeasurably intense for many Black women. Society has subscribed to certain beliefs about different groups, and these beliefs affect the roles, responsibilities, and identities of the individuals. They can have a positive or negative influence. Many principals have created professional identities that they have fine-tuned and learned to steer. Trial and error has helped them learn identity-fitting techniques, while other principals may still be learning how to effectively manage people, address supporters and nonsupporters, and be politically savvy. Regardless of how they develop their identity, principals work toward inventing and branding themselves, fulfilling public identities (e.g., caregiver) and trying out new identities, such as commander-and-chief. Black female principals must navigate their identities as bicultural beings with different stakeholder groups and within work spaces that are traditionally geared to monocultural White males.

Full-time life on a narrowboat is a novelty for so many of us, and is endlessly fascinating. How do people downsize their lives and belongings into what looks like a large, crayon-coloured floating toy-box? Narrowboat Life answers all the questions we've wanted to ask about the ins and outs of liveaboard life on the inland waterways. The book is filled with beautiful, enthralling photography of the waterways themselves, the narrowboats that occupy them and, most importantly, every nook and cranny of their insides. Should you become seduced, the author gives solid hands-on advice about how to make a narrowboat your home. Accompanying these absorbing images, the playful and always informative text satisfies our curiosity to know, among other things: · How do you fit all of your stuff into such a restricted space? · How much does a narrowboat cost? · How do you hold down a job if you're always on the move? · Does s/he (the cat, dog, parrot) live on the boat as well? · Is it cold in the winter? Jim Batty has lived, worked and continuously cruised a 53-foot narrowboat with his partner and their cat for the past six years. The book answers a distillation of all the queries he has fielded on an almost daily basis since moving aboard – through towpath and lockside conversations with young couples, those close to retirement, single men and women of all ages, young families, tourists, as well as talking with a host of inquisitive (and initially uncomprehending) friends, relatives and colleagues. Everyone, it seems, wants to know exactly what the live aboard life is like: inside and out.

Over the last two decades, research into epistasis has seen explosive growth and has moved the focus of research in evolutionary genetics from a traditional additive approach. We now know the effects of genes are rarely independent, and to reach a fuller understanding of the process of evolution we need to look at gene interactions as well as gene-environment interactions. This book is an overview of non-additive evolutionary genetics, integrating all work to date on all levels of evolutionary investigation of the importance of epistasis in the evolutionary process in general. It includes a historical perspective on this emerging field, in-depth discussion of terminology, discussions of the effects of epistasis at several different levels of biological organization and combinations of theoretical and experimental approaches to analysis.

Now updated for its second edition, Population Genetics is the classic, accessible introduction to the concepts of population genetics. Combining traditional conceptual approaches with classical hypotheses and debates, the book equips students to understand a wide array of empirical studies that are based on the first principles of population genetics. Featuring a highly accessible introduction to coalescent theory, as well as covering the major conceptual advances in population genetics of the last two decades, the second edition now also includes end of chapter problem sets and revised coverage of recombination in the coalescent model, metapopulation extinction and recolonization, and the fixation index.
