From tropics to tundra: Global convergence in plant functioning

Despite striking differences in climate, soils, and evolutionary history among diverse biomes ranging from tropical and temperate forests to alpine tundra and desert, we found similar interspecific relationships among leaf structure and function and plant growth in all biomes. Our results thus demonstrate convergent evolution and global generality in plant functioning, despite the enormous diversity of plant species and biomes. For 280 plant species from two global data sets, we found that potential carbon gain (photosynthesis) and carbon loss (respiration) increase in similar proportion with decreasing leaf life-span, increasing leaf nitrogen concentration, and increasing leaf surface area-to-mass ratio. Productivity of individual plants and of leaves in vegetation canopies also changes in constant proportion to leaf life-span and surface area-to-mass ratio. These global plant functional relationships have significant implications for global scale modeling of vegetation–atmosphere CO2 exchange.

Cost effectiveness of community leg ulcer clinics: randomised controlled trial

Assessment of Customer Service in Academic Health Care Libraries (ACSAHL): an instrument for measuring customer service*†

Objectives: In a pilot study, the library had good results using SERVQUAL, a respected and often-used instrument for measuring customer satisfaction. The SERVQUAL instrument itself, however, received some serious and well-founded criticism from the respondents to our survey. The purpose of this study was to test the comparability of the results of SERVQUAL with a revised and shortened instrument modeled on SERVQUAL. The revised instrument, the Assessment of Customer Service in Academic Health Care Libraries (ACSAHL), was designed to better assess customer service in academic health care libraries.

Enhancers increase the probability but not the level of gene expression.

We have studied enhancer function in transient and stable expression assays in mammalian cells by using systems that distinguish expressing from nonexpressing cells. When expression is studied in this way, enhancers are found to increase the probability of a construct being active but not the level of expression per template. In stably integrated constructs, large differences in expression level are observed but these are not related to the presence of an enhancer. Together with earlier studies, these results suggest that enhancers act to affect a binary (on/off) switch in transcriptional activity. Although this idea challenges the widely accepted model of enhancer activity, it is consistent with much, if not all, experimental evidence on this subject. We hypothesize that enhancers act to increase the probability of forming a stably active template. When randomly integrated into the genome, enhancers may affect a metastable state of repression/activity, permitting expression in regions that would not permit activity of an isolated promoter.

Women Leaders Resolving Conflict in Higher Education: A Feminist Epistemological Perspective

In an American postsecondary context, conflict is inherent (Gianneschi & Yanagiura, 2006; Valian, 1999). Successful navigation of conflict in the academy is vital for those who aspire to leadership positions (Nadler & Nadler, 1987; Walters, Stuhlmacher, & Meyer, 1998). Presently, however, women face significant barriers to achieving success in higher education administration, including gender expectations for conflict resolution behavior (Bartunek, 1992; Bowles, Babcock, & McGinn, 2005; Gayle, Preiss, & Allen, 2002). While a considerable body of literature exists for understanding gender negotiation, it remains rooted in a masculine paradigm (Kolb & Putnam, 2006; Shuter & Turner, 1997), and, as such, established theories lack a feminist epistemological perspective. Consequently, my primary research question is, How do women leaders experience and perceive conflict in the higher education work environment? I conduct a qualitative study that examines workplace conflict experiences of 15 women leaders from diverse personal and professional backgrounds. Hartsock's (1983) three-tiered gender-sensitive analysis of power, updated to include multicultural perspectives, serves as my theoretical framework. It is a lens through which I evaluate theories, finding multicultural organizational, higher education conflict, and gender negotiation theories most applicable to this study. The framework also creates the foundation upon which I build my study. Specifically, I determine that a feminist research method is most relevant to this investigation. To analyze data obtained through in depth interviews, I employ a highly structured form of grounded theory called dimensional analysis. Based on my findings, I co-construct with study participants a Feminist Conflict Process Theory and Flowchart in which initially the nature of the relationship, and subsequently the level of risk to the relationship, institution, or self, is evaluated. This study supports that which is observed in the conflict resolution practitioner literature, but is unique in its observation of factors that influence decisions within a dynamic conflict resolution process. My findings are significant to women who aspire to serve in leadership positions in higher education, as well as to the academy as a whole, for it expands our knowledge of women's ontological and epistemological perspectives on resolving conflict in postsecondary education.

Letter from Walter Kendall Watkins, 1905 October 21

One letter addressed "Dear Sir," enclosed with a one-page biographical sketch of Richard Harris. Walters indicates in the letter he had been permitted to examine the college silver, including the Great Salt, in the spring of 1905.

Chemical composition of the chalcophanite rich surface of an encrusted rock ashore Lake Macquarie, Australia

Mineralogical interest in the nature of manganese oxide particulates in natural marine water (Suess, 1979), natural lake water (Klaveness, 1977), and simulated lake water (Giovanoli, 1980), prompted a search for such particulates in a large New South Wales coastal lake. The investigated waters did show the existence of manganese oxide replacement phenomena in fragmentary sedimentary rocks near the south margin of Lake Macquarie. The black crusts of manganese oxide discovered on rocks close to the waterline have revealed a three layers structure. Layer A (0-35 micron), adjacent to the rock, is composed essentially of kaolinite of weathering origin, together with low levels of manganese oxide without detectable Zn. Layer B (35-80 micron) follows as a manganese oxide layer containing admixed kaolinite and low amounts of Zn. Layer C (80-130 micron) is the closest to the surface and is made of Chalcophanite containing 10-15% of ZnO.
