The impacts of land-cover composition on urban temperatures, including temperature extremes, are well documented. Much less attention has been devoted to the consequences of land-cover configuration, most of which addresses land surface temperatures. This study explores the role of both composition and configuration—or land system architecture—of residential neighborhoods in the Phoenix metropolitan area, on near-surface air temperature. It addresses two-dimensional, spatial attributes of buildings, impervious surfaces, bare soil/rock, vegetation and the “urbanscape” at large, from 50 m to 550 m at 100 m increments, for a representative 30-day high sun period. Linear mixed-effects models evaluate the significance of land system architecture metrics at different spatial aggregation levels. The results indicate that, controlling for land-cover composition and geographical variables, land-cover configuration, specifically the fractal dimension of buildings, is significantly associated with near-surface temperatures. In addition, statistically significant predictors related to composition and configuration appear to depend on the adopted level of spatial aggregation.

The relationship between the characteristics of the urban land system and land surface temperature (LST) has received increasing attention in urban heat island and sustainability research, especially for desert cities. This research generally employs medium or coarser spatial resolution data and primarily focuses on the effects of a few classes of land-cover composition and pattern at the neighborhood or larger level using regression models. This study explores the effects of land system architecture—composition and configuration, both pattern and shape, of fine-grain land-cover classes—on LST of single family residential parcels in the Phoenix, Arizona (southwestern USA) metropolitan area. A 1 m resolution land-cover map is used to calculate land architecture metrics at the parcel level, and 6.8 m resolution MODIS/ASTER data are employed to retrieve LST. Linear mixed-effects models quantify the impacts of land configuration on LST at the parcel scale, controlling for the effects of land composition and neighborhood characteristics. Results indicate that parcel-level land-cover composition has the strongest association with daytime and nighttime LST, but the configuration of this cover, foremost compactness and concentration, also affects LST, with different associations between land architecture and LST at nighttime and daytime. Given information on land system architecture at the parcel level, additional information based on geographic and socioeconomic variables does not improve the generalization capability of the statistical models. The results point the way towards parcel-level land-cover design that helps to mitigate the urban heat island effect for warm desert cities, although tradeoffs with other sustainability indicators must be considered.

This study examines the impact of spatial landscape configuration (e.g., clustered, dispersed) on land-surface temperatures (LST) over Phoenix, Arizona, and Las Vegas, Nevada, USA. We classified detailed land-cover types via object-based image analysis (OBIA) using Geoeye-1 at 3-m resolution (Las Vegas) and QuickBird at 2.4-m resolution (Phoenix). Spatial autocorrelation (local Moran’s I ) was then used to test for spatial dependence and to determine how clustered or dispersed points were arranged. Next, we used Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data acquired over Phoenix (daytime on 10 June and nighttime on 17 October 2011) and Las Vegas (daytime on 6 July and nighttime on 27 August 2005) to examine day- and nighttime LST with regard to the spatial arrangement of anthropogenic and vegetation features. Local Moran’s I values of each land-cover type were spatially correlated to surface temperature. The spatial configuration of grass and trees shows strong negative correlations with LST, implying that clustered vegetation lowers surface temperatures more effectively. In contrast, clustered spatial arrangements of anthropogenic land-cover types, especially impervious surfaces and open soil, elevate LST. These findings suggest that city planners and managers should, where possible, incorporate clustered grass and trees to disperse unmanaged soil and paved surfaces, and fill open unmanaged soil with vegetation. Our findings are in line with national efforts to augment and strengthen green infrastructure, complete streets, parking management, and transit-oriented development practices, and reduce sprawling, unwalkable housing development.

This study seeks to determine the role of land architecture—the composition and configuration of land cover—as well as cadastral/demographic/economic factors on land surface temperature (LST) and the surface urban heat island effect of Phoenix, Arizona. It employs 1 m National Agricultural Imagery Program data of land-cover with 120mLandsat-derived land surface temperature, decomposed to 30 m, a new measure of configuration, the normalized moment of inertia, and U.S. Census data to address the question for two randomly selected samples comprising 523 and 545 residential neighborhoods (census blocks) in the city. The results indicate that, contrary to most other studies, land configuration has a stronger influence on LST than land composition. In addition, both land configuration and architecture combined with cadastral, demographic, and economic variables, capture a significant amount of explained variance in LST. The results indicate that attention to land architecture in the development of or reshaping of neighborhoods may ameliorate the summer extremes in LST.

We investigated the spatial and temporal variation in June mean minimum temperatures for weather stations in and around metropolitan Phoenix, USA, for the period 1990 to 2004. Temperature was related to synoptic conditions, location in urban development zones (DZs), and the pace of housing construction in a 1 km buffer around fixed-point temperature stations. June is typically clear and calm, and dominated by a dry, tropical air mass with little change in minimum temperature from day to day. However, a dry, moderate weather type accounted for a large portion of the inter-annual variability in mean monthly minimum temperature. Significant temperature variation was explained by surface effects captured by the type of urban DZ, which ranged from urban core and infill sites, to desert and agricultural fringe locations, to exurban. An overall spatial urban effect, derived from the June monthly mean minimum temperature, is in the order of 2 to 4 K. The cumulative housing build-up around weather sites in the region was significant and resulted in average increases of 1.4 K per 1000 home completions, with a standard error of 0.4 K. Overall, minimum temperatures were spatially and temporally accounted for by variations in weather type, type of urban DZ (higher in core and infill), and the number of home completions over the period. Results compare favorably with the magnitude of heating by residential development cited by researchers using differing methodologies in other urban areas.

The purpose of this project was to evaluate the State Bar of New Mexico's (SBNM) new podcast series, SBNM is Hear. The podcast was initially developed as a member outreach tool and a new platform for professional development and survey questions were developed to gauge the podcast’s effectiveness in these two areas. An electronic survey was deployed to active members of the SBNM through email. Respondents were asked questions regarding their demographics, whether they had listened to the series, and what content they would like to hear in the future. The survey resulted in 103 responses, of which 60% indicated that they had not listened to the podcast. The results showed that listenership was evenly divided between generations and that more females listened to at least one episode. The open-ended responses indicated that the two cohorts of respondents (listeners and non- listeners) viewed the podcast a potential connection to the New Mexico judiciary. Future recommendations include conducting an annual survey to continue to understand the effectiveness of the podcast and solicit feedback for continued growth and improvement

Online learning platforms, or learning management

As the impact of technology on daily life continues to grow, online learning platforms for primary, secondary, post-secondary, and professional institutions find ways to:

1. Connect peers and instructors through digital communication.
2. Engage users more fully in learning.
3. Provide access to resources that enhance deep-impact education.

Online learning platforms, or learning management systems (LMS), are used to connect instructors and students through synchronous and asynchronous engagement tools, provide space for the transfer of resources and ideas, and track progress. However, these platforms were designed with more mainstream purposes - and more digitally savvy - users in mind.

Adult learning programs (with members ages 50+) currently have no online learning and sharing platform specifically designed to fit the needs and desires of their users. Despite the multitude of barriers to successful use, adult learning programs recognize the need to engage with members digitally and are seeking an online learning platform centered around their users.

This project, utilizing best practices in technical communication and mixed methods user experience research, broadens the boundaries of communication design by creating an online learning platform prototype specifically for adults ages 50+ through the lens of information design, content management, and user experience outcomes.

This report aims to provide The Arts Partnership, an arts-based non-profit organization in the Fargo, ND-Moorhead, MN area, with recommendations on improving its “Connecting the Dots” weekly e-newsletter. The research was conducted using three separate channels – a quantitative survey of the current e-newsletter recipients, a qualitative coding exercise to uncover themes in each e-newsletter, and an analysis of the top-clicked links in each e-newsletter. The original research, combined with information gleaned from the literature review, results in seven recommendations The Arts Partnership can implement into its current program. These recommendations include reducing the amount of HTML in each e-newsletter to avoid SPAM traps, keeping the email as scannable as possible, maintaining its subscriber base to eliminate waste, ensuring its e-newsletters are mobile-responsive, improving the subject line of the e-newsletters, and finally, considering using a different email program that provides more features The Arts Partnership can use to continue to improve its newsletters.
