Clarity, confusion, and idea refining in ecology

Calcium-dependent potassium channels in the heart: clarity and confusion.

Small-conductance Ca2+-activated K+ (SK) channels are widely expressed throughout the body. After initial dismissal of a functional role for SK channels in the heart, a series of elegant studies from the Chiamvimonvat laboratory rekindled interest, as did subsequent work suggesting that tachypaced rabbit pulmonary veins have enhanced SK channel trafficking to the cell membrane that accelerates ...

Evaluation of cardiac output monitoring devices: clarity or confusion?

Clarity from Confusion: Using Intended Interactions to Design Information Systems

Two tools are described that help designers visualize the structure of a system in the requirements phase of a project. First, a matrix is constructed that represents the tendency of components to interact. The matrix is derived from sequence diagrams, which in turn are based on textual scenarios. This interaction matrix is transformed into a structure plot of the system, showing a graph of the...

IDEA AND PERSPECT IVE Temporal ecology in the Anthropocene

E. M. Wolkovich, B. I. Cook, K. K. McLauchlan and T. J. Davies Abstract Two fundamental axes – space and time – shape ecological systems. Over the last 30 years spatial ecology has developed as an integrative, multidisciplinary science that has improved our understanding of the ecological consequences of habitat fragmentation and loss. We argue that accelerating climate change – the effective m...

Clinical nurse specialists and nurse practitioners: title confusion and lack of role clarity.

Title confusion and lack of role clarity pose barriers to the integration of advanced practice nursing roles (i.e., clinical nurse specialist [CNS] and nurse practitioner [NP]). Lack of awareness and understanding about NP and CNS roles among the healthcare team and the public contributes to ambiguous role expectations, confusion about NP and CNS scopes of practice and turf protection. This pap...
