Keep It Shutby Karen Ehman explores how to better control your tongue, knowing what to say and how to say it, and realizing when it is best to say nothing at all.
From Bible times to modern times women have struggled with their words. What to say and how to say it. What not to say. When it is best to remain silent. And what to do when youâve said something you wish you could now take back. In this book a woman whose mouth has gotten her into loads of trouble shares the hows (and how-not-tos) of dealing with the tongue.
Beyond just a âhow not to gossipâ book, this book explores what the Bible says about the many ways we are to use our words and the times when we are to remain silent. Karen will cover using our speech to interact with friends, co-workers, family, and strangers as well as in the many places we use our words in private, in public, online, and in prayer. Even the words we say silently to ourselves. She will address unsolicited opinion-slinging, speaking the truth in love, not saying words just to people-please, and dealing with our verbal anger.
Christian women struggle with their mouths. Even though we know that Scripture has much to say about how we areâand are notâto use our words, this is still an immense issue, causing heartache and strain not only in family relationships, but also in friendships, work, and church settings.
Today, many organizations use Control Objectives for Information and related Technology (Cobit) in their planning and control cycle of IT, in order to ensure that IT brings value to their businesses. One lesson learned through IT governance is that realizing value from IT requires a mature organization that can deliver such value. Performance measurement and management, therefore, is a key element in realizing business value through IT.
Enterprise IT Governance, Business Value and Performance Measurement reports on high-level academic research outcomes, providing evidence-based insight into the management and contribution of IT within organizations. It also offers practical insights, models, and tools that are instrumental in gaining business value from IT. With contributions from 35 international professionals, this valuable reference appeals to both academic and practitioners in the field of IT management and business and IT alignment.
Innovation and Scaling for Impact forces us to reassess how social sector organizations create value. Drawing on a decade of research, Christian Seelos and Johanna Mair transcend widely held misconceptions, getting to the core of what a sound impact strategy entails in the nonprofit world. They reveal an overlooked nexus between investments that might not pan out (innovation) and expansion based on existing strengths (scaling). In the process, it becomes clear that managing this tension is a difficult balancing act that fundamentally defines an organization and its impact.
The authors examine innovation pathologies that can derail organizations by thwarting their efforts to juggle these imperatives. Then, through four rich case studies, they detail innovation archetypes that effectively sidestep these pathologies and blend innovation with scaling. Readers will come away with conceptual models to drive progress in the social sector and tools for defining the future of their organizations.
The Complete Guide to Optimizing Systems Performance
Written by the winner of theÂ 2013 LISA Award for Outstanding Achievement in System Administration
Large-scale enterprise, cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on LinuxÂ® and UnixÂ® performance, while illuminating performance issues that are relevant to all operating systems. Youâll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based UbuntuÂ®, FedoraÂ®, CentOS, and the illumos-based JoyentÂ® SmartOSâ¢ and OmniTI OmniOSÂ®. He systematically covers modern systems performance, including the âtraditionalâ analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the âunknown unknownsâ of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish.
