Relatively Speaking: An Account of the Relationship between Language and Thought in the Color Domain
This chapter is divided into six sections. The first sets out the background of the debate about the relationship between language and cognition in the color domain. The second explains how recent studies of color recognition employing visual search tasks have clarified this relationship. This section also argues that these studies point to the existence of two separate systems that influence perception and categorization of color; one of which is linguistically based, and one of which is not affected by language. The third section critically evaluates recent claims that there are similarities between color terms in the world's languages that point to the existence of color universals. The fourth section examines children's color term acquisition in an attempt to trace the mechanisms bywhich color categories are acquired. It also discusses whether infants have an innate prepartitioned organization of color categories that is overridden during the learning process. The two final sections outline some outstanding questions, note some methodological constraints on the conclusions that can be drawn from the accumulated evidence, and argue that much more empirical investigation is still needed in this field
Lifelong Learning in the County: A Context of Nature, Community, and Simplicity
The purpose of this study was to understand more about the impact of living in a rural area on personal learning with older adults. This is important to consider because of the higher concentration of older adults in rural areas. This qualitative research was based on twenty interviews with older adults. All of the participants lived in the same rural county in south Georgia (USA). One of the results from this research was the positive description of living in a rural area. Despite literature that often describes rural areas in a negative light; all of the participants spoke about the positive aspect of living in a rural area. These positive characteristics were discussed as simplicity, quiet, community, and nature. Negative aspects of rural life were mentioned as lack of resources and fewer people. Ten participants were purposefully chosen who were identified as active older adults who continue to learn. Two interviews with each person were conducted and the interviews were transcribed verbatim. The findings were based on recurring themes as a result of comparative analysis throughout the process. Public schools can contribute to the continued education of older adults by holding various classes as well as incorporating volunteerism

The Doctor of Ministry Cohort As A Transformative Dialogue Group
Transformative Dialogue in a Doctor of Ministry Program can function as a transformative learning experience that fosters Professional Ministry Development for ministers. Transformative dialogic moments shape the identity of learners by means of creating learning spaces to facilitate Professional Ministry Development. The sharing, respect, and commitment to the ideas and needs of the group can serve as a mephato which is a cohort called together to receive training and/or mobilize each other to construct useful knowledge together as a collective. These groups or cohorts provide a unique container for transformative learning within their relationships fostered through self-awareness, group identity, and critical consciousness. Triggered by moments of cognitive dissonance, the Doctor of Ministry group works and dialogues in peer sessions and unique ministry contexts as a means for personal and social transformation. Transformative Learning literature emphasizes the role of relationships with others in such a group as the Petri dish— the growth-supporting environment— that provides both the container and space in which such learning can occur, and the dialogical processes through which learning takes place. In this article, the authors explore the concept of Transformative Dialogue Groups as a development tool for Professional Ministry Training in a Doctor of Ministry cohort or mephato

Abilene Christian College Lectures - 1946
INTRODUCTION
It has been our purpose at Abilene Christian College down through the years to provide in the Annual Bible Lectureship programs that which would be appropriate for the time and most useful to the students and to the Lectureship visitors. The general subject for the 1946 lectures is “Things That Cannot Be Shaken.” This subject was selected because one of the battles, if not the battle, which the church faces today is against those forces which would undermine the bases of gospel truth. Many denominational leaders, in one way or another, are denying even the fundamentals of fundamentals— God is, the Bible is God\u27s Revelation, Jesus Christ is the Son of God and The Kingdom Cannot Be Shaken. Many others, some without knowing what they do, are accepting false teachings and ideologies which, if allowed to run their course, will destroy all true religion. It is believed that the 1946 lectures and this edition of the lectures will help toward establishing in the hearts of men the truth of the important theses discussed. It was the purpose of those who arranged the program that the Lectureship should, also, hold up Christianity as a working, practical religion; hence, the meetings on “Work in New Fields” and “The Church at Work.” The attendance of this Lectureship was the largest in the history of these yearly meetings. On Wednesday evening Brother Nichol spoke to a crowd of approximately 1700 persons. Other evening lectures were attended by crowds almost as large. Visitors came from more than a score of States and, also, from Canada and Mexico.
It is the hope of all of us at the College that the fellowship of the 1946 Lectureship and the instruction given by the various speakers will continue to do good for years without end.

Majoritarian Blotto contests with asymmetric battlefields: an experiment on apex games
We investigate a version of the classic Colonel Blotto game in which individual battlefields may have different values. Two players allocate a fixed discrete budget across battlefields. Each battlefield is won by the player who allocates the most to that battlefield. The player who wins the battlefields with highest total value receives a constant winner payoff, while the other player receives a constant loser payoff. We focus on apex games, in which there is one large and several small battlefields. A player wins if he wins the large and any one small battlefield, or all the small battlefields. For each of the games we study, we compute an equilibrium and we show that certain properties of equilibrium play are the same in any equilibrium. In particular, the expected share of the budget allocated to the large battlefield exceeds its value relative to the total value of all battlefields, and with a high probability (exceeding 90% in our treatments) resources are spread over more battlefields than are needed to win the game. In a laboratory experiment, we find that strategies that spread resources widely are played frequently, consistent with equilibrium predictions. In the treatment where the asymmetry between battlefields is strongest, we also find that the large battlefield receives on average more than a proportional share of resources. In a control treatment, all battlefields have the same value and our findings are consistent with previous experimental findings on Colonel Blotto games
Restaurateurs' perceptions of location and design
The aim of this paper is to gather the perceptions of restaurateurs on restaurant location and design
dimensions. In this study the researcher tested the perceptions of restaurateurs using thirteen layout and
design dimensions evident in the independent full-service restaurant segment. The outcomes to be tested
were presented to restaurateurs in a questionnaire uploaded on a web-based research system "survey
monkey". This was emailed to 3 286 restaurateurs with 303 responses being received. Interestingly
respondents perceive the ambience of a restaurant (M=3.34) and toilet facilities (M=3.34) to be the most
important location and design aspects that influence customer satisfaction when dining out. This is
significant because most restaurateurs spend the largest part of their marketing budget on promoting the
food quality price
Isolated oxygen defects in 3C- and 4H-SiC: A theoretical study
Ab initio calculations in the local-density approximation have been carried out in SiC to determine the possible configurations of the isolated oxygen impurity. Equilibrium geometry and occupation levels were calculated. Substitutional oxygen in 3C-SiC is a relatively shallow effective mass like double donor on the carbon site (O-C) and a hyperdeep double donor on the Si site (O-Si). In 4H-SiC O-C is still a double donor but with a more localized electron state. In 3C-SiC O-C is substantially more stable under any condition than O-Si or interstitial oxygen (O-i). In 4H-SiC O-C is also the most stable one except for heavy n-type doping. We propose that O-C is at the core of the electrically active oxygen-related defect family found by deep level transient spectroscopy in 4H-SiC. The consequences of the site preference of oxygen on the SiC/SiO2 interface are discussed
Homologous and heterologous desensitization of guanylyl cyclase-B signaling in GH3 somatolactotropes
The guanylyl cyclases, GC-A and GC-B, are selective receptors for atrial and C-type natriuretic peptides (ANP and CNP, respectively). In the anterior pituitary, CNP and GC-B are major regulators of cGMP production in gonadotropes and yet mouse models of disrupted CNP and GC-B indicate a potential role in growth hormone secretion. In the current study, we investigate the molecular and pharmacological properties of the CNP/GC-B system in somatotrope lineage cells. Primary rat pituitary and GH3 somatolactotropes expressed functional GC-A and GC-B receptors that had similar EC50 properties in terms of cGMP production. Interestingly, GC-B signaling underwent rapid homologous desensitization in a protein phosphatase 2A (PP2A)-dependent manner. Chronic exposure to either CNP or ANP caused a significant down-regulation of both GC-A- and GC-B-dependent cGMP accumulation in a ligand-specific manner. However, this down-regulation was not accompanied by alterations in the sub-cellular localization of these receptors. Heterologous desensitization of GC-B signaling occurred in GH3 cells following exposure to either sphingosine-1-phosphate or thyrotrophin-releasing hormone (TRH). This heterologous desensitization was protein kinase C (PKC)-dependent, as pre-treatment with GF109203X prevented the effect of TRH on CNP/GC-B signaling. Collectively, these data indicate common and distinct properties of particulate guanylyl cyclase receptors in somatotropes and reveal that independent mechanisms of homologous and heterologous desensitization occur involving either PP2A or PKC. Guanylyl cyclase receptors thus represent potential novel therapeutic targets for treating growth-hormone-associated disorders

Analysis of fractures in volcanic cores from Pahute Mesa, Nevada Test Site
The Nevada Test Site (NTS), located in Nye County, southern Nevada, was the location of 828 announced underground nuclear tests, conducted between 1951 and 1992. Approximately one-third of these tests were detonated near or below the water table. An unavoidable consequence of these testing activities was introducing radionuclides into the subsurface environment, impacting groundwater. Groundwater flows beneath the NTS almost exclusively through interconnected natural fractures in carbonate and volcanic rocks. Information about these fractures is necessary to determine hydrologic parameters for future Corrective Action Unit (CAU)-specific flow and transport models which will be used to support risk assessment calculations for the U.S. Department of Energy, Nevada Operations Office (DOE/NV) Underground Test Area (UGTA) remedial investigation. Fracture data are critical in reducing the uncertainty of the predictive capabilities of CAU-specific models because of their usefulness in generating hydraulic conductivity values and dispersion characteristics used in transport modeling. Specifically, fracture aperture and density (spacing) are needed to calculate the permeability anisotropy of the formations. Fracture mineralogy information is used qualitatively to evaluate diffusion and radionuclide retardation potential in transport modeling. All these data can best be collected through examination of core samples
