Sale Price, Marketing Time, and Limited Service Listings: The Influence of Home Value and Market Conditions
Local markets for real estate brokerage services typically exhibit fairly strict pricing. Increased popularity of limited service brokerages provides an opportunity to study any loss in utility by sellers using these firms. Anecdotal evidence suggests that sellers experience a decreased selling price or an increased marketing time when utilizing limited service brokers, but there has been little prior empirical work. This study finds that limited service listings sell for significantly more and spend significantly less time on the market than traditional listings. The price and marketing time impacts vary by home value and local market conditions.
Acoustic signatures of the seafloor: Tools for predicting grouper habitat
Groupers are important components of commercial and recreational fisheries. Current methods of diver-based
grouper census surveys could potentially benefit from development of remotely sensed methods of seabed classification. The goal of the present study was to determine if areas of high grouper abundance have characteristic acoustic signatures. A commercial acoustic seabed mapping system, QTC View Series V, was used to
survey an area near Carysfort Reef, Florida Keys. Acoustic data were clustered using QTC IMPACT software, resulting in three main acoustic classes covering 94% of the area surveyed. Diver-based data indicate that one of the acoustic classes corresponded to hard substrate and the other two represented sediment. A new measurement of seabed heterogeneity, designated acoustic variability, was also computed from the acoustic survey data in order to more fully characterize the acoustic response (i.e., the signature) of the seafloor.
When compared with diver-based grouper census data, both acoustic classification and acoustic variability were significantly different at sites with and without groupers. Sites with groupers were characterized by hard bottom substrate and high acoustic variability. Thus, the acoustic
signature of a site, as measured by acoustic classification or acoustic variability, is a potentially useful tool for stratifying diver sampling effort for grouper census

Creating a Volunteer ESL Program in Madrid: Action Research for Program Design and Service Learning
One of the challenges of accommodating North American students in study abroad programs is providing opportunities for volunteerism, a given in North American culture but not in Spain. Thus, Saint Louis University\u27s Madrid campus began a program during the Fall semester 2001 in which fluent speakers of English volunteer to teach the English language to members of the Madrid community, who attend classes free of charge. We-Anne as faculty advisor, Therese as program coordinator, and Tom as the first volunteer teacher-had very little idea of how the program would unfold, since we did not know what kind of response it would initially receive, both from the community and from possible volunteers. This was the first time we offered a program like this, and we did not know of any other similar programs to turn to for suggestions. From the outset, we decided to incorporate action research as an investigative means of moving toward our desired goal, finding the optimal approach to fit the needs of both the community and the volunteer teachers. Preliminary results from data analysis corroborate our efforts. After discussing our results, we suggest that programs such as this one can be of great benefit for volunteer teachers who would like to explore their development, in terms of understanding classroom contexts and the wider cultural context of their host country
Assessing Depression-Related Mental Health Literacy among Young Adults
Background and Purpose: Young adults who are 18 to 25 years old have the highest prevalence of depression (10.9%). Depression is a risk factor for suicide. Mental health literacy (MHL) is a key component in assessing recognition and help-seeking for depression with suicidal ideation. This study investigated MHL as it relates to help-seeking for depression with suicidal ideation. Methods: A crosssectional survey design was used. Participants were young adults (n= 430, ages 18 to 24 years old) who lived, worked, and/or attended school in San Francisco, California. Reavley and colleaguesâ MHL survey was modified and made available in English, Spanish, and Chinese. Results: Several background factors were positively, though weakly, correlated to MHL, based on the r coefficient. Significant factors were: being female [r=.12,

Charred forests increase snowmelt: Effects of burned woody debris and incoming solar radiation on snow ablation
We document effects of postfire forest conditions on snow accumulation, albedo, and ablation in the Oregon Cascades. We measured snow water equivalent, solar radiation, snow albedo, and snowpack surface debris at a pair of burned and unburned forest plots. Snow accumulation was greater in the burned forest; however, the snowpack disappeared 23days earlier and had twice the ablation rate than in the unburned forest. Snow albedo was 40% lower in the burned forest during ablation, while approximately 60% more solar radiation reached the snow surface, driving a 200% increase in net shortwave radiation. Significant amounts of pyrogenic carbon particles and larger burned woody debris shed from standing charred trees accumulated on the snowpack and darkened its surface. Spatial analysis showed that across the Western U.S., 80% of all forest fires occurred in the seasonal snow zone, and were 4.4 times larger than fires outside the seasonal snow zone.Keywords:

Central Asia and the globalisation of the contemporary legal consciousness
What is the logic which governs the processes of legal globalization? How does the transnational proliferation of legal forms operate in the contemporary geo-juridical space? What are the main defining characteristics of the currently dominant mode of transnational legal consciousness and how can the concept of legal consciousness help us understand better the historical ebb and flow of the Western-led projects of good governance promotion in regions like Central Asia after the fall of the Soviet Union? Using Duncan Kennedyâs seminal essay Three Globalizations of Law and Legal Thought as its starting platform, this essay seeks to explore these and a series of other related questions, while also drawing on the work of the Greek Marxist lawyer-philosopher Nicos Poulantzas to help elucidate some latent analytical stress-points in Kennedyâs broader theoretical framework. Reacting against the neo-Orientalist tone adopted across much of the contemporary field of Central Asian studies, it develops an alternative account of the internal history of the legal-globalizational encounter between the Western-based reform entrepreneurs and the national legal-political elites in Central Asia in the post-1991 period, complementing it with a detailed description of the general institutional and discursive structures within which this encounter took place
The Cold Peace: Russo-Western Relations as a Mimetic Cold War
In 1989â1991 the geo-ideological contestation between two blocs was swept away, together with the ideology of civil war and its concomitant Cold War played out on the larger stage. Paradoxically, while the domestic sources of Cold War confrontation have been transcended, its external manifestations remain in the form of a âlegacyâ geopolitical contest between the dominant hegemonic power (the United States) and a number of potential rising great powers, of which Russia is one. The post-revolutionary era is thus one of a âcold peaceâ. A cold peace is a mimetic cold war. In other words, while a cold war accepts the logic of conflict in the international system and between certain protagonists in particular, a cold peace reproduces the behavioural patterns of a cold war but suppresses acceptance of the logic of behaviour. A cold peace is accompanied by a singular stress on notions of victimhood for some and undigested and bitter victory for others. The perceived victim status of one set of actors provides the seedbed for renewed conflict, while the âvictoryâ of the others cannot be consolidated in some sort of relatively unchallenged post-conflict order. The âuniversalismâ of the victors is now challenged by Russia's neo-revisionist policy, including not so much the defence of Westphalian notions of sovereignty but the espousal of an international system with room for multiple systems (the Schmittean pluriverse)
An inversion in the wiring of an intercellular signal: evolution of Wnt signaling in the nematode vulva
Signal transduction pathways are largely conserved throughout the animal
kingdom. The repertoire of pathways is limited and each pathway is used in
different intercellular signaling events during the development of a given
animal. For example, Wnt signaling is recruited, sometimes redundantly with
other molecular pathways, in four cell specification events during
Caenorhabditis elegans vulva development, including the activation of vulval
differentiation. Strikingly, a recent study finds that Wnts act to repress
vulval differentiation in the nematode Pristionchus pacificus, demonstrating
evolutionary flexibility in the use of intercellular signaling pathways
Mechanism of aortic medial matrix remodeling is distinct in patients with bicuspid aortic valve
ObjectivesPatients with bicuspid aortic valves (BAV) are predisposed to developing ascending thoracic aortic aneurysms (TAA) at an earlier age than patients who develop degenerative TAAs and have a tricuspid aortic valve (TAV). The hypothesis tested is that BAV-associated aortopathy is mediated by a mechanism of matrix remodeling that is distinct from that seen in TAAs of patients with tricuspid aortic valves.MethodsAortic specimens were collected during ascending aortic replacement, aortic valve replacement, and heart transplants from nonaneurysmal (NA) donors and recipients. Matrix architecture of the aortic media was assessed qualitatively using multiphoton microscopy followed by quantification of collagen and elastin fiber orientation. α-Elastin was determined and matrix maturity was assessed by quantifying immature and mature collagen and lysyl oxidase (Lox) expression and activity in aortic specimens. Matrix metalloproteinase-2/9 activity was quantified in aortic smooth muscle cells.ResultsElastin and collagen fibers were more highly aligned in BAV-NA and BAV-TAA cases than in TAV-TAA cases, whereas TAV-TAA cases were more disorganized than TAV-NA cases. α-Elastin content was unchanged. Immature collagen was reduced in BAV-NA and BAV-TAA cases when compared with TAV-NA and TAV-TAA cases. Mature collagen was elevated in TAV-TAA cases compared with TAV-NA and BAV-TAA cases. There was a trend toward elevated Lox gene expression and activity and matrix metalloproteinase-2/9 activity for TAV-TAA, BAV-NA, and BAV-TAA specimens.ConclusionsThe highly aligned matrix architecture in patients with BAVs indicates that wall remodeling is distinct from TAV-TAA. Altered matrix architecture and reduced collagen maturity suggest that the effector molecules mediating the remodeling of TAAs are different in BAV and TAV cases
