Pepperdine University is a private, nonprofit, coeducational research university affiliated with the Churches of Christ. The university's 830-acre campus overlooking the Pacific Ocean in unincorporated Los Angeles County, California, United States, near Malibu is the location for Seaver College, the School of Law, the Graduate School of Education and Psychology, the Graziadio School of Business and Management, and the School of Public Policy. Courses are taught at the main campus, six graduate campuses in southern California, and at international campuses in Germany, England, Italy, China, Switzerland and Argentina. The Ed.D. program in Organizational leadership, has held international courses in China, Argentina, Chile, Belize, Costa Rica, and India.The 2015 edition of U.S. News and World Report lists Pepperdine as a "more selective" national university and ranks it 54th in this category.

Amazon's Mechanical Turk (MTurk) provides researchers with access to a diverse set of people who can serve as research participants, making the process of data collection a streamlined and cost-effective one. While a small number of studies are often cited to support the use of this methodology, there remains a need for additional analyses of the quality of the research data. In the present study, MTurk-based responses for a personality scale were found to be significantly less reliable than scores previously reported for a community sample. While score reliability was not affected by the length of the survey or the payment rates, the presence of an item asking respondents to affirm that they were attentive and honest was associated with more reliable responses. Best practices for MTurk-based research and continuing research needs are addressed. © 2014 Elsevier Ltd. All rights reserved. Source

Over 70 species of intertidal fishes from 12 families breathe air while emerging from water. Amphibious intertidal fishes generally have no specialized air-breathing organ but rely on vascularized mucosae and cutaneous surfaces in air to exchange both oxygen and carbon dioxide. They differ from air-breathing freshwater fishes in morphology, physiology, ecology and behaviour. Air breathing and terrestrial activity are present to varying degrees in intertidal fish species, correlated with the tidal height of their habitat. The gradient of amphibious lifestyle includes passive remainers that stay in the intertidal zone as tides ebb, active emergers that deliberately leave water in response to poor aquatic conditions and highly mobile amphibious skipper fishes that may spend more time out of water than in it. Normal terrestrial activity is usually aerobic and metabolic rates in air and water are similar. Anaerobic metabolism may be employed during forced exercise or when exposed to aquatic hypoxia. Adaptations for amphibious life include reductions in gill surface area, increased reliance on the skin for respiration and ion exchange, high affinity of haemoglobin for oxygen and adjustments to ventilation and metabolism while in air. Intertidal fishes remain close to water and do not travel far terrestrially, and are unlikely to migrate or colonize new habitats at present, although in the past this may have happened. Many fish species spawn in the intertidal zone, including some that do not breathe air, as eggs and embryos that develop in the intertidal zone benefit from tidal air emergence. With air breathing, amphibious intertidal fishes survive in a variable habitat with minimal adjustments to existing structures. Closely related species in different microhabitats provide unique opportunities for comparative studies. © 2013 The Fisheries Society of the British Isles. Source

We contend that in order to compete effectively in a digital business environment, firms should develop a transparency strategy by selectively disclosing information outside the boundaries of the firm. We make the case for transparency strategy by showing why it is relevant in the digital business world, and the consequences of not having such a strategy. We then provide some foundations to develop the strategy and make a call for research. Source

Broadband is becoming increasingly important to national economies and the personal lives of users. However, broadband availability and adoption are not diffusing in rural and urban areas at the same rates. This article updates the rural broadband digital divide, with special attention paid to mobility. Empirical estimations of broadband provision and usage in the US show that rural areas have fewer high-speed fixed and mobile providers but more slower-speed fixed providers than urban areas. While rural availability of mobile broadband is lower than in urban areas, it still helps fill in gaps in fixed broadband coverage in rural areas. The rural gap in fixed broadband usage remains, but the mobile broadband usage gap disappears after controlling for household demographics. The raw broadband usage gaps between rural and urban households are proportionally greater for low-income households. The potential for mobile broadband to benefit rural areas through economic development is also examined. © 2012 Elsevier Ltd. All rights reserved. Source

The protein kinase Hog1 (high osmolarity glycerol 1) was discovered 20 years ago, being revealed as a central signaling mediator during osmoregulation in the budding yeast Saccharomyces cerevisiae. Homologs of Hog1 exist in all evaluated eukaryotic organisms, and this kinase plays a central role in cellular responses to external stresses and stimuli. Here, we highlight the mechanism by which cells sense changes in extracellular osmolarity, the method by which Hog1 regulates cellular adaptation, and the impacts of the Hog1 pathway upon cellular growth and morphology. Studies that have addressed these issues reveal the influence of the Hog1 signaling pathway on diverse cellular processes.
