The Critical Target Audience: Communicating Water Conservation Behaviors to Critical Thinking Styles
Although water covers approximately 70% of the planet, only a fraction is fresh water, and even less is used as a major source of drinking water. With the continuous increase in the amount of water used in modern standards of living, the quantity of water available is decreasing. The public is beginning to understand water needs to be conserved and they must play a role in water conservation. While previous literature examined how the majority of messages were catered toward the cost-effectiveness of conserving water, this study proposed how using a specific audience attribute could affect behaviors. The purpose of the study was to determine if critical thinking style can be used in the development of future communication strategies to improve water conservation behaviors. The findings of this study provided evidence of a relationship between critical thinking style and the level of engagement in water conservation behaviors. Recommendations suggested targeting the two constructs of critical thinking style, information seekers and engagers, in two different ways. Since the seekers prefer to gather information by seeking the sources themselves, communicators should focus on developing quality information about water conservation and placing it in easily accessible communications channels for the information seeker. On the other hand, a different communications approach should be taken with the engagers, who prefer to learn through their environment. Communicators should focus on communicating to the engager through the environment in word-of-mouth situations using traditional means such as opinion leaders as well as social media
Water use in Florida: Examining Perceptions of Water use Based on Visual Images
Residents and decision makers often perceive information regarding water use differently. This is an issue in Florida where water quantity is a concern, and the distribution of accurate knowledge will be necessary to assist in effective conservation efforts. This study used two online surveys to gain insight into Florida residents’ and decision makers’ (county commissioners, county clerks and county managers) perceptions of water use based on visual images. Using non-probability opt-in sampling methods a total of 525 Florida residents’ responses were collected, and in a second survey 169 decision makers’ responses were collected. Respondents were asked to associate a specific water user, based on a visual, with high, moderate, or low water usage. A series of chi-square tests were used to compare and test for differences between Florida residents’ and decision makers’ perceptions, revealing that significant differences in perception did exist. The identification of these differences was used to develop recommendations for enhancing education and communication regarding water use
Testing the Usability of Communication Materials through Heat Maps in Online Survey Platforms
Usability tests can be used to enhance the communication strategies of agricultural organizations as they identify the use and value of a communications tool from a target audience’s perspective. Further, online survey methodology has provided a place where communicators can gather information from a diverse target audience. One way communicators can create a usability test in online surveys is through the use of heat map questions. Heat map questions provide a platform where agricultural communication professionals and researchers can identify how well a target audience uses a communication material. By merging heat maps and value-based questions, researchers and communicators can evaluate the usability and value of a communication material. Heat maps allow agricultural communicators to evaluate communication materials such as websites and iers, gather users’ feedback and identify strategies to enhance agricultural communication materials. This article provides steps to incorporate heat map questions into online survey, tips for using heat map tests, and methods to interpret heat map results

Lamm, Valluri, Jentschura and Weniger comment on "A Convergent Series for the QED Effective Action" by Cho and Pak [Phys. Rev. Lett. vol. 86, pp. 1947-1950 (2001)]
Complete results were obtained by us in [Can. J. Phys. 71, 389 (1993)] for
convergent series representations of both the real and the imaginary part of
the QED effective action; these derivations were based on correct intermediate
steps. In this comment, we argue that the physical significance of the
"logarithmic correction term" found by Cho and Pak in [Phys. Rev. Lett. 86,
1947 (2001)] in comparison to the usual expression for the QED effective action
remains to be demonstrated. Further information on related subjects can be
found in Appendix A of hep-ph/0308223 and in hep-th/0210240.Comment: 1 page, RevTeX; only "meta-data" update
Rotation-disk connection for very low mass and substellar objects in the Orion Nebula Cluster
Angular momentum loss requires magnetic interaction between the forming star
and both the circumstellar disk and the magnetically driven outflows. In order
to test these predictions many authors have investigated a rotation-disk
connection in pre-main sequence objects with masses larger than about 0.4Msun.
For brown dwarfs this connection was not investigated as yet because there are
very few samples available. We aim to extend this investigation well down into
the substellar regime for our large sample of BDs in the Orion Nebula Cluster,
for which we have recently measured rotational periods. In order to investigate
a rotation-disk correlation, we derived near-infrared (NIR) excesses for a
sample of 732 periodic variables in the Orion Nebula Cluster with masses
ranging between 1.5-0.02 Msun and whose IJHK colors are available.
Circumstellar NIR excesses were derived from the Delta[I-K] index. We performed
our analysis in three mass bins.We found a rotation-disk correlation in the
high and intermediate mass regime, in which objects with NIR excess tend to
rotate slower than objects without NIR excess. Interestingly, we found no
correlation in the substellar regime. A tight correlation between the
peak-to-peak (ptp) amplitude of the rotational modulation and the NIR excess
was found however for all objects with available ptp values. We discuss
possible scenarios which may explain the lack of rotation-disk connection in
the substellar mass regime. One possible reason could be the strong dependence
of the mass accretion rate on stellar mass in the investigated mass range.Comment: 12 pages, 7 figures, accepted for publication "Astronomy and

Harmonic maps from degenerating Riemann surfaces
We study harmonic maps from degenerating Riemann surfaces with uniformly
bounded energy and show the so-called generalized energy identity. We find
conditions that are both necessary and sufficient for the compactness in
and modulo bubbles of sequences of such maps.Comment: 27 page
