KERNEL MORPHOLOGY VARIATION IN A POPULATION DERIVED FROM A SOFT BY HARD WHEAT CROSS AND ASSOCIATIONS WITH END-USE QUALITY TRAITS,

JOURNAL OF FOOD QUALITY, Issue 4 2000
CHRISTINE J. BERGMAN
ABSTRACT Physical attributes, including kernel morphology, are used to grade wheat, and indicate wheat milling and baking quality (MBQ). Using a recombinant inbred population derived from a soft by hard wheat cross, this study quantified kernel traits' sources of variation, studied their heritability, and relationships between morphological and MBQ traits. Transgressive segregation occurred for all traits. Thousand-kernel weight (TKW) and kernel texture (NIR-T) were primarily [source]


Decision Factors and the Recognition of Medical Specialty in Patients Receiving Cosmetic Laser and Intense Pulsed Light Treatment

DERMATOLOGIC SURGERY, Issue 12 2007
TIEN-YI TZUNG MD
BACKGROUND In addition to dermatologists and plastic surgeons, physicians of other medical specialties also provide cosmetic laser and light treatment. OBJECTIVE This study aimed to determine the major decision factors in patients who received cosmetic laser or intense pulsed light treatment and how they perceived different medical specialties in providing such services. METHODS The method of factor analysis was adopted to extract the common characteristics (major decision factors) from a list of 17 items patients would regard as important when they planned to receive laser and intense pulsed light treatment. In addition, the level of recognition of different medical specialties in cosmetic patients was indirectly forecast using an analytic hierarchy process. RESULTS Medical competence (0.3296) was the most important decision factor, followed by recommendation (0.2198), friendliness (0.1350), cost (0.1307), complete service (0.0984), and the physical attributes of the physician (0.0865). Dermatologists and plastic surgeons outscored cosmetic practitioners in five factors except for cost, in which the plastic surgeons were weakest. CONCLUSION Medical competence and recommendation are the core issues for cosmetic patients. Dermatologists and plastic surgeons gain better overall recognition than physicians of other medical specialties in cosmetic patients. [source]


To generalize or not to generalize: spatial categories are influenced by physical attributes and language

DEVELOPMENTAL SCIENCE, Issue 1 2009
Susan J. Hespos
The current work explored the conditions under which infants generalize spatial relationships from one event to another. English-learning 5-month-olds habituated to a tight- or loose-fit covering event dishabituated to a change in fit during a containment test event, but infants habituated to a visually similar occlusion event did not. Thus, infants' responses appeared to be driven by the physical nature of the fit rather than visual similarity. This response pattern was replicated with Korean-speaking adults, but English-speaking adults showed no sensitivity to change in fit for either event. These findings suggest that language development links linguistic forms to universal, pre-existing representations of meaning, and that linguistic experience can shape sensitivity to distinctions that are marked in one's native language.

Topographic spatial characterisation of grey seal Halichoerus grypus breeding habitat at a sub-seal size spatial grain

ECOGRAPHY, Issue 3 2001
S. D. Twiss
Expansion within breeding colonies may critically depend upon the availability of suitable breeding habitat. Here we use topographic modelling in a GIS to characterise suitable pupping habitat and accurately predict the pattern of colonisation in an expanding grey seal breeding colony-the Isle of May (Scotland), We use high resolution images from large format aerial photographs of the colony to generate sub-metre accurate Digital Terrain Models (DTMs), GIS modelling with these DTMs provides topographic measures of elevation, slope and ease of access to sea and freshwater pools at a 2 m grid cell size. Seal locations during the 1994 breeding season, with sex-age class, were also digitised from the same images. We examine how the physical attributes of cells (locations) with and without pups differ and identify areas suitable for pupping but remaining unoccupied during 1994. We predict patterns of future colonisation by characterising areas differentiated by the densities of pups within 5 m grid cells and identifying areas, both occupied or unoccupied, with a potential for increased future pupping densities. Our predictions were tested by examining pup distributions observed in the 1998 breeding season. Occupied sites were significantly closer to freshwater pools and access to the sea (p < 0.001) than unoccupied sites suggesting that proximity to water may restrict colony expansion before all areas of suitably flat terrain are occupied. All pup density classes occurred in sites with similar slope values and distance to pools. However, higher pupping densities occurred closer to access points (p = 0.014). Pup densities observed in 1998 revealed that our 1994 predictions were accurate (p < 0.0001). Only 12% of 466 grid cells had higher densities in 1998 than predicted, of which 88% differed by only 1 pup. These incorrectly classified cells occurred at the expanding edge of the colony (in a more topographically homogenous area) and at the main access points from the sea (major traffic zones). These results demonstrate the value of the accurate quantification of topographic parameters at the appropriate spatial grain (in this case below the size of the individual) for use in habitat classification and predictions of habitat utilization.

Environmental Predictors of Geographic Variation in Human Mating Preferences

ETHOLOGY, Issue 4 2002
Kevin J. McGraw
Sexual selection theory classically posits consistent and directional mate-preferences for male traits that provide benefits to females. However, flexible mate-choice tactics may persist within a species when males display multiple desirable features that confer different benefits to females under variable environmental conditions. Ecological factors such as population density, resource demand, and sex ratio can influence the value that female animals place on certain male characteristics across mating environments. In this study, I used human mate-preference data from `lonely hearts' advertisements in the newspapers of 23 cities in the USA to assess geographic differences in female preferences for male traits (e.g. physical attributes, resource-holding potential, emotional characteristics, personal interests) in relation to these ecological parameters. I found that females placed more emphasis on the resource-accruing ability of prospective mates in densely populated cities and cities having greater resource demands (higher cost of living). In contrast, women from densely populated or resource-demanding cities placed less emphasis on the emotional aspects or personal interests of males. Preferences for physical features were not environmentally linked, but instead were a function of the degree to which females advertised their own physical attractiveness. Collectively, these results suggest that certain mate-choice criteria employed by women are sensitive to variation in local environmental conditions and that variable levels of resource or mate availability may favor different mating tactics across human populations.

Effects of attention and arousal on early responses in striate cortex

EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 1 2005
Vahe Poghosyan
Abstract Humans employ attention to facilitate perception of relevant stimuli. Visual attention can bias the selection of a location in the visual field, a whole visual object or any visual feature of an object. Attention draws on both current behavioral goals and/or the saliency of physical attributes of a stimulus, and it influences activity of different brain regions at different latencies. Attentional effect in the striate and extrastriate cortices has been the subject of intense research interest in many recent studies. The consensus emerging from them places the first attentional effects in extrastriate areas, which in turn modulate activity of V1 at later latencies. In this view attention influences activity in striate cortex some 150 ms after stimulus onset. Here we use magnetoencephalography to compare brain responses to foveally presented identical stimuli under the conditions of passive viewing, when the stimuli are irrelevant to the subject and under an active GO/NOGO task, when the stimuli are cues instructing the subject to make or inhibit movement of his/her left or right index finger. The earliest striate activity was identified 40,45 ms after stimulus onset, and it was identical in passive and active conditions. Later striate response starting at about 70 ms and reaching a peak at about 100 ms showed a strong attentional modulation. Even before the striate cortex, activity of the right inferior parietal lobule was modulated by attention, suggesting this region as a candidate for mediating attentional signals to the striate cortex.

Lexical studies of Filipino person descriptors: adding personality-relevant social and physical attributes

EUROPEAN JOURNAL OF PERSONALITY, Issue 4 2008
Shellah Myra Imperio
Abstract Lexical studies have focused on traits. In the Filipino language, we investigated whether additional dimensions can be identified when personality-relevant terms for social roles, statuses and effects, plus physical attributes, are included. Filipino students (N,=,496) rated themselves on 268 such terms, plus 253 markers of trait and evaluative dimensions. We identified 10 dimensions of social and physical attributes,Prominence, Uselessness, Attractiveness, Respectability, Uniqueness, Destructiveness, Presentableness, Strength, Dangerousness and Charisma. Most of these dimensions did not correspond in a one-to-one manner to Filipino or alternative trait models (Big Five, HEXACO, ML7). However, considerable redundancy was observed between the social and physical attribute dimensions and trait and evaluative dimensions. Thus, social and physical attributes communicate information about personality traits, and vice versa. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Thermal model based on temperature dependent absorptivity and thermophysical properties along with defocusing of laser beam, multiple track induced preheating effect, and heat transfer was developed to incorporate effect of multiple passes on machined cavity. Predicted and experimentally measured values of physical attributes showed decent match. [source]


High-Resolution Patterning of Hydrogels in Three Dimensions using Direct-Write Photofabrication for Cell Guidance

ADVANCED FUNCTIONAL MATERIALS, Issue 22 2009
Stephanie K. Seidlits
Abstract The development of three-dimensional, spatially defined neuronal cultures that mimic chemical and physical attributes of native tissue is of considerable interest for various applications, including the development of tailored neuronal networks and clinical repair of damaged nerves. Here, the use of multiphoton excitation to photocrosslink protein microstructures within three-dimensional, optically transparent hydrogel materials, such as those based on hyaluronic acid, is reported. Multiphoton excitation confines photocrosslinking to a three-dimensional voxel with submicron spatial resolution, enabling fabrication of protein matrices with low- to sub-micrometer feature sizes by scanning the focus of a laser relative to the reagent solution. These methods can be used to create complex three-dimensional architectures that provide both chemical and topographical cues for cell culture and guidance, providing for the first time a means to direct cell adhesion and migration on size scales relevant to in vivo environments. Using this approach, guidance of both dorsal root ganglion cells (DRGs) and hippocampal neural progenitor cells (NPCs) along arbitrary, three-dimensional paths is demonstrated. [source]


THE UNIQUENESS OF THE AMERICAN RELIGIOUS LANDSCAPE

GEOGRAPHICAL REVIEW, Issue 3 2001
WILBUR ZELINSKY
ABSTRACT. The assemblage of objects that constitute the publicly visible religious landscape of the United States,houses of worship and a variety of church-related enterprises,deviates so markedly from its counterparts in other lands that we can regard its uniqueness as a significant argument for American exceptionalism. The diagnostic features in question include the extraordinary number and variety of churches and denominations, their special physical attributes, the near-random microgeography of churches in urban areas, and, most especially, their nomenclature and the widely distributed signage promoting godliness and religiosity. Such landscape phenomena suggest connections with much-deeper issues concerning the origin and evolution of American society and culture. [source]

INTERNATIONAL JOURNAL OF DAIRY TECHNOLOGY, Issue 2 2008
KALYANI NAIR
Samples of direct acidified whey based lassi like beverage were prepared with different proportions of guar gum, CMC and inulin and were examined for sensory and physical attributes. The optimisation was carried out using central composite rotatory design (CCRD) of response surface methodology (RSM). Response surface analysis revealed that sensory scores for flavour, consistency, colour and appearance and overall acceptability of lassi like beverage varied from 6.50 to 7.25, 6.16 to 7.12, 6.20 to 7.41 and 5.96 to 7.20 respectively. The results of analysis showed that all the examined model solutions had significant influence on the different parameters indicating that the statistical model designed for these attributes fitted well in all the aspects of model efficiency check (R2 >85%).

Cognitive and Mobility Profile of Older Social Dancers

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 8 2006
Joe Verghese MD
OBJECTIVES: To define the cognitive and physical attributes of regular social dancing so as to help establish its health benefits and help plan future dance interventions to prevent adverse outcomes in older adults such as falls, slow gait, and dementia. DESIGN: Cross-sectional survey with two-group comparison. SETTING: Bronx County, New York. PARTICIPANTS: Twenty-four cognitively normal older social dancers (OSDs) were compared with 84 age-, sex-, and education-matched older nondancers (ONDs) participating in a community-based study. MEASUREMENTS: Motor and cognitive performance was assessed using validated clinical and quantitative methods. RESULTS: There were no differences in the frequency of participation in other cognitive and physical leisure activities, chronic illnesses, or falls between OSDs and ONDs. Cognitive test performance was not different between OSDs and ONDs. OSDs had better balance but not strength than ONDs. OSDs had a longer mean stride±standard deviation than ONDs (117.8±10.5 cm vs 103.4±20.2 cm, P=.008) on quantitative gait assessment, with a more stable pattern during walking with reduced stance time (63.9% vs 65.9%, P=.01), longer swing time (36.1% vs 34.1%, P=.01), and shorter double support time (27.9% vs 30.9%, P=.03). CONCLUSION: The results of this study suggest that long-term social dancing may be associated with better balance and gait in older adults. [source]


ORIGINAL ARTICLE: The biogeography of avian extinctions on oceanic islands

JOURNAL OF BIOGEOGRAPHY, Issue 6 2008
Tim J. Karels
Abstract Aim, To test the influences of island area, island isolation, and human-introduced mammalian predators on avian extinctions that have occurred on oceanic islands worldwide. Location, The oceanic islands of the world. Methods, We augmented and re-examined an existing data set for 218 oceanic islands by means of causal modelling using path analysis (a form of structural equation modelling) and a null model. Results, The number of extinctions was not a simple function of the number of bird species on the various islands. Whereas introduced mammalian predators had an influence on the number of extinctions, island area (via indirect influences) and isolation (via direct influences) were equally or more important. Main conclusions, The multiple influences of physical and biotic factors on past extinctions can be revealed through modelling the causal influences of physical attributes of islands on biological characteristics, and the causal influences of both physical and biological characteristics on extinctions.

The Social Ecology of Marriage and Other Intimate Unions

JOURNAL OF MARRIAGE AND FAMILY, Issue 2 2000
Ted L. Huston
This article provides an interdisciplinary framework for studying marital and other intimate relationships. Three levels of analysis are distinguished: (a) the society, characterized in terms of both macrosocietal forces and the ecological niches within which particular spouses and couples function; (b) the individual spouses, including their psychosocial and physical attributes, as well as the attitudes and beliefs they have about each other and their relationship; and (c) the marriage relationship, viewed as a behavioral system embedded within a larger network of close relationships. The discussion focuses primarily on the interplay between the spouses and their marriage, emphasizing the importance of distinguishing, both analytically and operationally, the individual from the dyadic (or group) levels of analysis. It is also argued that in order to appreciate how marriages work, social scientists must understand not only how these 2 levels of analysis interpenetrate each other but also how macrosocietal forces and the ecological niches within which couples live impinge on partners and their marital relationship.

A near-infrared spectroscopic investigation of relative density and crushing strength in four-component compacts

JOURNAL OF PHARMACEUTICAL SCIENCES, Issue 3 2009
Steven M. Short
Abstract Near-infrared spectroscopy (NIRS) is commonly employed for the analysis of chemical and physical attributes of intact pharmaceutical compacts. Specifically, NIRS has proven useful in the nondestructive measurement of tablet hardness or crushing strength. Near-infrared (NIR) reflectance and transmittance spectra were acquired for 174 13-mm compacts, which were produced according to a four-constituent mixture design (29 points) composed of anhydrous theophylline, lactose monohydrate, microcrystalline cellulose, and soluble starch. Six compacts were produced for each design point by compacting at multiple pressures. Physical testing and regression analyses were used to model the effect of variation in relative density (and crushing strength) on NIR spectra. Chemometric analyses demonstrated that the overall spectral variance was strongly influenced by anhydrous theophylline as a result of the experimental design and the component's spectroscopic signature. The calibration for crushing strength was more linear than the relative density model, although accuracy was poorer in comparison to the density model due to imprecision of the reference measurements. Based on the consideration of reflectance and transmittance measurements, a revised rationalization for NIR sensitivity to compact hardness is presented. © 2008 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 98:1095,1109, 2009 [source]


Analysis of consumers' preferences and behavior with regard to horse meat using a structured survey questionnaire

ANIMAL SCIENCE JOURNAL, Issue 6 2009
Woon Yong OH
ABSTRACT In this study, a structured survey questionnaire was used to determine consumers' preferences and behavior with regard to horse meat at a horse meat restaurant located in Jeju, Korea, from October 1 to December 24, 2005. The questionnaire employed in this study consisted of 20 questions designed to characterize six general attributes: horse meat sensory property, physical appearance, health condition, origin, price, and other attributes. Of the 1370 questionnaires distributed, 1126 completed questionnaires were retained based on the completeness of the answers, representing an 82.2% response rate. Two issues were investigated that might facilitate the search for ways to improve horse meat production and marketing programs in Korea. The first step was to determine certain important factors, called principal components, which enabled the researchers to understand the needs of horse meat consumers via principal component analysis. The second step was to define consumer segments with regard to their preferences for horse meat, which was accomplished via cluster analysis. The results of the current study showed that health condition, price, origin, and leanness were the most critical physical attributes affecting the preferences of horse meat consumers. Four segments of consumers, with different demands for horse meat attributes, were identified: origin-sensitive consumers, price-sensitive consumers, quality and safety-sensitive consumers, and non-specific consumers. Significant differences existed among segments of consumers in terms of age, nature of work, frequency of consumption, and general level of acceptability of horse meat. [source]


Categorical Perception and Conceptual Judgments by Nonhuman Primates: The Paleological Monkey and the Analogical Ape

COGNITIVE SCIENCE - A MULTIDISCIPLINARY JOURNAL, Issue 3 2000
Roger K. R. Thompson
Studies of the conceptual abilities of nonhuman primates demonstrate the substantial range of these abilities as well as their limitations. Such abilities range from categorization on the basis of shared physical attributes, associative relations and functions to abstract concepts as reflected in analogical reasoning about relations between relations. The pattern of results from these studies point to a fundamental distinction between monkeys and apes in both their implicit and explicit conceptual capacities. Monkeys, but not apes, might be best regarded as "paleo-logicans" in the sense that they form common class concepts of identity on the basis of identical predicates (i.e., shared features). The discrimination of presumably more abstract relations commonly involves relatively simple procedural strategies mediated by associative processes likely shared by all mammals. There is no evidence that monkeys can perceive, let alone judge, relations-between-relations. This analogical conceptual capacity is found only in chimpanzees and humans. Interestingly, the "analogical ape," like the child, can make its analogical knowledge explicit only if it is first provided with a symbol system by which propositional representations can be encoded and manipulated.
