Full textAbstract:
The present article focuses on the peculiarities of the usage of colour terminology in advertisements. We live in a colourful world and there are great many colour words to describe it. We also live in a world where advertisement has become an accompanying phenomenon of our everyday life. It is obvious that the language of advertising has its specific features and it seems worth trying to reveal the role and the meaning of the colours used in advertisements. Colour terms are known to be linguistic universals which have certain associations attached to each of them. We may suppose that the colours that are mostly used in the advertisements are the basic colour terms. The spheres where we expect to find wider usage of colour terms should be the ones connected with fashion industry.

We investigated whether the learning of colour terms in childhood is constrained by a developmental order of acquisition as predicted by Berlin and Kay [1969 Basic Color Terms (Berkeley, CA: University of California Press)]. Forty-three children, aged between 2 and 5 years and grouped according to language ability, were given two tasks testing colour conceptualisation. Colour comprehension was assessed in a spoken-word-to-colour-matching task in which a target colour was presented in conjunction with two distractor colours. Colour naming was measured in an explicit naming task in which colours were presented individually for oral naming. Results showed that children's knowledge of basic-colour terms varied across tasks and language age, providing little support for a systematic developmental order. In addition, we found only limited support for an advantage for the conceptualisation of primary (red, green, blue, yellow, black, white) compared to non-primary colour terms across tasks and language age. Instead, our data suggest that children acquire reliable knowledge of nine basic colours within a 3-month period (35.6 to 39.5 months) after which there is a considerable lag of up to 9 months before accurate knowledge of the final two colours (brown and grey) is acquired. We propose that children acquire colour term knowledge in two distinct time frames that reflect the establishment of, first, the exterior (yellow, blue, black, green, white, pink, orange, red, and purple) and, second, the interior structure (brown and grey) of conceptual colour space. These results fail to provide significant support for the order predicted by Berlin and Kay, and suggest, instead, that the development of colour term knowledge is largely unconstrained.

Full textAbstract:
The paper presents the analysis of colour perception and its interpretation in psychology and symbolism; it highlights colour properties and the approaches to colour studies largely in linguistics. One of the features of colours is their ability to express human emotions and feelings, either positive or negative (verbally/ nonverbally), and to create certain atmosphere in the situation abound in colours. Shades of colours can be regarded as a lexico-semantic group formed by adjectives and nouns, which can be simple, derived, and compound words. Short texts include many colour terms expressing such colour properties, as hue, saturation, tone, lightness, intensity; each of them contributes to decoding of some culture-specific features hidden in Sudden fiction. The analysis of Sudden fiction shows that short stories have specific composition, where colour terms perform different functions. Descriptive functions are mainly connected with focal colours and identify objects’ properties. Other functions, such as character-generating, associative, metaphoric, symbolic, semiotic, and culture specific are more complicated. Their identification implies additional knowledge of cultural, social, and historical planes.

Full textAbstract:
Colour is a strong communication method which, despite their denotative meanings, conveys different positive and negative messages since their meanings and connotations are language and culture based. The present study aims at investigating the meanings and the frequency of colour terms used in Bahdini Kurdish proverbs. To conduct the present study, data have been collected from different Kurdish proverb books. The results arrived at in the present study showed that the shades and hues of the basic colour terms are used a little in Kurdish proverbs compared with the basic colour terms. The colours are not occurred equally in Kurdish proverbs. Each colour term gives a different meaning, and sometimes the same connotation is interpreted by more than one colour term. Moreover, they have both positive and negative connotations.

Colour plays a key role in people’s communication. Languages represent the gradation of colours in nature by a series of discrete categories. These categories of colour differ along with the different cultures. Colour distinctions and meanings also play a major role in different religions. A certain colour may have a particular meaning in Christianity and another different meaning. There is no single language is said to include all colour variations. Colour distinctions and meanings play a major role in different religions. A certain colour may have a particular meaning in Christianity and another different meaning. This paper aims at identifying the basic colour terms in the Glorious Qur'an and making structural and semantic analyses of them. It is hypothesized that the Glorious Qur’an contains particular colour terms that occupy various grammatical classes and indicates specific functions. Furthermore, some are linked to each other by semantic relations. The major findings arrived at are the following: there are six basic colour terms used in the Glorious Qur’an; they are white, black, green, yellow, blue, and red. Colour terms used in the Glorious Qur’an have various structures in Arabic syntax. Secondly, semantic variations are found in many verses of the Glorious Qur’an that include colour terms. Thirdly, cultural differences affect the usage of colour in language. Finally, the use of colour terms in the Glorious Qur’an is meant to apply different functions of the terms, such as the visual, the aesthetic, the symbolic, and the expressive functions. one colour might be interpreted in one way in a language and in a totally different way in another.

This article elaborates on the results of a field experiment conducted among speakers of the Chakali language, spoken in northern Ghana. In the original study, the Color-aid Corporation Chart was used to perform the focal task in which consultants were asked to point at a single colour tile on the chart. However, data from the focal task could not be analysed since the Color-aid tiles had not yet been converted into numerical values set forth by the Commission internationale de l’éclairage (CIE). In this study, the full set of 314 Color-aid tiles were measured for chromaticity and converted into the CIE values at the Daylight Laboratory of the Norwegian University of Science and Technology. This article presents the conversion methodology and makes the results of the measurements, which are available in the Online Appendix. We argue that some visual-perception terms cannot be reliably ascribed to colour categories established by the Color-aid Corporation. This suggests that the ideophonic expressions in the dataset do not denote ‘colours’, as categorised in the Color-aid system, as it was impossible to average the consultants’ data into a CIE chromaticity diagram, illustrate the phenomena on the Natural Colour System (NCS) Circle and Triangle diagrams, and conduct a statistical analysis. One of the implications of this study is that a line between a visual-perception term and a colour term could be systematically established using a method with predefined categorical thresholds.

Most people are born with the natural ability to see and distinguish the colours of objects and things in everyday life, but to explain in words what colour is, is a more complicated matter. Scientists have generally accepted that, physically, colour is the visual aspect of electromagnetic radiant energy having a spectral composition ranging in wavelength from about 380 to about 720 nanometres. From the psychological point of view, it is a sensation produced on the eye and in the brain by rays of light when resolved by selective reflection. The problems raised by the study of colour use are thus interdisciplinary.

Linguistic categorisation of colours: relative basicness of French colour termsCategorisation is one of the basic cognitive processes. Because of the continuous character of the colour spectrum, colour terms constitute an interesting material to study linguistic categorisation. The first part of this article offers a review of research on the linguistic categorisation of colours, especially on basic colour terms and prototypes. In the second part, the results of an empirical study on the basicness of French colour terms will be presented. The results suggest that colour terms are categorised as prototypically structured concepts, which supports the hypothesis of the relative basicness of colour terms.

Full textAbstract:
Berlin & Kay’s basic colour term framework claims that there is an ordering in the diachronic development of languages’ colour systems. One generalisation is that primary colours, WHITE, BLACK, RED, YELLOW, GREEN, BLUE, are lexicalised before derived colours, which are perceptual blends, e.g. ORANGE is the blend of YELLOW and RED. The colour systems of Lower Sorbian and Upper Sorbian offer an important typological contribution. It is already known that primary colour space can contract upon the emergence of a basic derived term; our findings indicate that derived categories also shift as colour systems develop. Tsakhur offers corroborating evidence.

Full textAbstract:
Colours and emotions are associated in languages and traditions. Some of us may convey sadness by saying feeling blue or by wearing black clothes at funerals. The first example is a conceptual experience of colour and the second example is an immediate perceptual experience of colour. To investigate whether one or the other type of experience more strongly drives colour-emotion associations, we tested 64 congenitally red-green colour-blind men and 66 non-colour-blind men. All participants associated 12 colours, presented as terms or patches, with 20 emotion concepts, and rated intensities of the associated emotions. We found that colour-blind and non-colour-blind men associated similar emotions with colours, irrespective of whether colours were conveyed via terms (r = .82) or patches (r = .80). The colour-emotion associations and the emotion intensities were not modulated by participants’ severity of colour blindness. Hinting at some additional, although minor, role of actual colour perception, the consistencies in associations for colour terms and patches were higher in non-colour-blind than colour-blind men. Together, these results suggest that colour-emotion associations in adults do not require immediate perceptual colour experiences, as conceptual experiences are sufficient.

Full textAbstract:
This thesis examines usage of English colour terms in context, based on an extensive computerised text corpus, the Bank of English. It describes the ways in which English colour terms may be used to refer to nuances outside their normal area of designation and to attributes outside the colour domain. Usage patterns are analysed on three different levels: with regard to the overall frequency of occurrences, nominal domains and individual tokens, respectively.
Cognitive linguistics supplies the theoretical framework employed in the analyses of the observed patterns. The study identifies three types of usage where colour terms refer to peripheral colour nuances or to concepts outside the colour domain: classifying, figurative and marked usage.
When a colour term has a classifying function, it can be used outside the normal area of designation. This usage is analysed as a type of reference-point construction where a term referring to a salient point in the colour domain is used to subcategorise an entity whose actual colour may be only a peripheral member of the category named by the colour term. An analysis of the OED and the Bank of English shows that this type of usage is primarily restricted to a few of the most salient basic terms.
This study points to the close affinities between classifying and figurative usage. Figurative expressions of colour terms frequently have a classifying function. I argue that figurative meanings are derived through two types of metonymy: +SALIENT ATTRIBUTE FOR OBJECT+ and +SALIENT CONCRETE ATTRIBUTE FOR SALIENT ABSTRACT ATTRIBUTE+.
Marked usage arises when specific colour terms are used in nominal domains where the specificity is not expected. This phenomenon is consequently confined to non-basic colour terms.
On the basis of the established patterns of usage and the frequency of occurrences, this thesis suggests that the colour category may be analysed as a radial category, with the basic colour terms forming the centre.

Full textAbstract:
Much research suggests that there exist universal colour names. Investigations involving paint and paper media have revealed co-incidence of especially salient names and their concomitant sensations, within and between cultures. These names have been called Basic Colour Terms (BCfs), and their prototypical sensations focal colours (or foci). The highest levelof colour name development within cultures includes eleven BCfs. A literature review revealed certain omissions in the colour naming work. Firstly was a lack of usage of CRT-baseddisplay of colours. This was considered an important omission given the implicit, but largely untested assumption that CRT and surface media may be equivalent. A second omission identified was a lack of detailed quantification of realistic naming behaviour. Two CRT-based experiments were then devised to quantify colour naming, one involving unconstrained naming of colours, one involving selection of which colours were exemplars of (thirteen) pre-generated colour names. These experiments revealed certain regularities in naming within a (perceptually uniform) colour space. Thus a naming space and its underlying structure was obtained. Naming space was found to be a composite of they way membership of (BCf) categories was expressed, and an underlying set of five fundamental colour sensations. Evidencewas then forthcoming that this structure might be modelable. The quantified data obtained was then used to investigate the search-efficacy of easy to name colours. Such easy to name palettes were generated, based on the data obtained, and compared with colorimetrically matched, and highly discriminable palettes. It was found that easy to name as a colour palette variable was meaningful, and capable of adjusting user performance, despite evidence that individuals may possess relatively stable, idiosyncratic colour vocabularies. That CRT work has generality was verified by comparison of foci obtained from a series of studies involving different media. Although some differences were evident, these followed clear patterns which were not inconsistent with universal colour naming. This thesis suggests that there exist complex aspects of colour naming behaviour which are nevertheless understandable, and largely predictable. Such theoretical data should allow for improvements in certain human-interactions, where tasks involve naming colours.

This thesis investigates language acquisition and evolution, using the methodologies of Bayesian inference and expression-induction modelling, making specific reference to colour term typology, and syntactic acquisition. In order to test Berlin and Kay's (1969) hypothesis that the typological patterns observed in basic colour term systems are produced by a process of cultural evolution under the influence of universal aspects of human neurophysiology, an expression-induction model was created. Ten artificial people were simulated, each of which was a computational agent. These people could learn colour term denotations by generalizing from examples using Bayesian inference, and the resulting denotations had the prototype properties characteristic of basic colour terms. Conversations between these people, in which they learned from one-another, were simulated over several generations, and the languages emerging at the end of each simulation were investigated. The proportion of colour terms of each type correlated closely with the equivalent frequencies found in the World Colour Survey, and most of the emergent languages could be placed on one of the evolutionary trajectories proposed by Kay and Maffi (1999). The simulation therefore demonstrates how typological patterns can emerge as a result of learning biases acting over a period of time. Further work applied the minimum description length form of Bayesian inference to modelling syntactic acquisition. The particular problem investigated was the acquisition of the dative alternation in English. This alternation presents a learnability paradox, because only some verbs alternate, but children typically do not receive reliable evidence indicating which verbs do not participate in the alternation (Pinker, 1989). The model presented in this thesis took note of the frequency with which each verb occurred in each subcategorization, and so was able to infer which subcategorizations were conspicuously absent, and so presumably ungrammatical. Crucially, it also incorporated a measure of grammar complexity, and a preference for simpler grammars, so that more general grammars would be learned unless there was sufficient evidence to support the incorporation of some restriction. The model was able to learn the correct subcategorizations for both alternating and non-alternating verbs, and could generalise to allow novel verbs to appear in both constructions. When less data was observed, it also overgeneralized the alternation, which is a behaviour characteristic of children when they are learning verb subcategorizations. These results demonstrate that the dative alternation is learnable, and therefore that universal grammar may not be necessary to account for syntactic acquisition. Overall, these results suggest that the forms of languages may be determined to a much greater extent by learning, and by cumulative historical changes, than would be expected if the universal grammar hypothesis were correct.

Full textAbstract:
Colour is a basic aspect of perception and the perception of colour varies from individual to individual. This indicates that the perception of colours mean different semantics in various contexts to different individuals. Therefore, these differences in perception forms to behave in different attitudes towards colours among individuals and it is likely to achieve different attitudinal responses to colours from individuals. Relying on the effects of colours on individuals, the initial interest of this thesis is to explore the attitudinal approaches of individuals to colours.
This thesis is first and foremost exploratory in nature. This thesis intended as a first step towards exploring the ways in which the individuals think of, construe and give meaning to colours in their own words. The subjective approach proposed in terms of this thesis is based on the underlying philosophy behind Personal Construct Theory (PCT). In order to elicit the individuals&rsquoways of construing and giving meaning to colours in their own words, an experiment was conducted with the utilisation of the Repertory Grid Technique (RGT). Sixty undergraduate students of Middle East Technical University (METU) Faculty of Architecture were voluntarily participated in the experiment. As a stimuli, eleven basic colours which were black, grey, white, yellow, orange, red, pink, purple, brown, blue and green were utilised. For the second step, this thesis intended investigating the structure and interrelations between the elicited attitudes of individuals and eleven basic colours. As a result of the experiment, 60 repertory grids were elicited and were analysed by using the qualitative and quantitative applications of content analysis. The resulted data afterwards were analysed by using multivariate statistical analysis methods. The overall results of this research can support certain information for further scientific investigations on colour perception and colour psychology. Additionally, the results of this research can help and guide designers to attain objective understandings about the individuals&rsquo
attitudes to colours. This can contribute to designers as a practical worthwhile during colour design and colour planning in their products and services.

Forder, Lewis. "The time course of the influence of colour terms on visual processing." Thesis, University of Sussex, 2016. http://sro.sussex.ac.uk/id/eprint/60415/.
Full textAbstract:
This thesis explores whether colour terms (e.g., “red”, “blue”, “purple”, etc.) influence visual processing of colour, and if so, the time course of any effect. Broadly, this issue relates to debate concerning whether language affects the way we perceive the world (i.e., the theory of linguistic relativity). Three of the experiments conducted used the event-related potential method (ERP), taking electrophysiological measurements of visual processing and visual cognition in human participants. The ERP provides high-resolution information about the timing of neural activity in the brain and can therefore be used to effectively investigate the time course of a potential influence of colour terms on visual processing. The first study, using a behavioural approach, identified that colour terms can influence the detection of colours and colour-associated objects suppressed from awareness by continuous flash suppression. The second study found that a cross-linguistic difference in colour lexicons affected a post-perceptual ERP component (the P2-N2 complex), but not sensory ERP components occurring early in visual processing. However, the third study found that differences in colour naming within a language do affect an early sensory ERP component (the P1). The final study used ERPs to identify a post-perceptual neural marker (in the posterior P2 component) for the unique ‘pure' hues (red, yellow, green, and blue), which had previously only been defined and identified linguistically. All of the studies provide evidence that colour terms affect colour processing, and the specific time course of this effect is identified as being task-dependent. These findings have implications for broader debate about the influence of language on visual cognition and perception.

Full textAbstract:
“Gold” is a colour indicating the colour of an object. It is a unique colour word which represents the colour of gold. From ancient to the present, “gold” is a common Chinese word which is frequently used in the literature. Furthermore, “gold” is the symbol of goodness in the traditional Chinese society. Nowadays, “gold” represents noble, luxury, wealth, hope, etc in the cultural connotation.
This dissertation consists of five chapters. The first chapter introduces the research background, purpose of the topic and key points of the study.
The second chapter is divided into three parts. In the first part, it begins to look for the semantic origin of the colour word “gold” by analyzing its original meaning, aboriginal meaning and quotative meaning. In the second part, it demonstrates the development of cultural connotation in China and elaborates the cultural connotation in the present Chinese society. In the third part, the colour word “gold” is compared with the colour words “yellow” and “red” to identify their differences and similarities of cultural connotations.
In the third chapter, it mainly focuses on phraseology function of “gold” and its combinations. Meanwhile, the aspects of word-formation, syntactical functions, sentence structure of “gold” and its combinations will be discussed.
The fourth chapter analyzes the usage and effect of “gold” and its combinations with regard to rhetoric. It also illustrates and explains the features of usage and rhetorical effects on seven categories of figures of speech which are fairly typical.
The last chapter is the conclusion of the whole dissertation. “Gold” is a very unique colour word which differentiates from other colour words such as “red”, “yellow” and so on. “Gold” has been representing a positive image from the past, even nowadays, “gold” is still one of the most glamorous colours.published_or_final_version

Die Arbeit prüft, inwieweit die Übersetzungstheorien von Otto Kade et al., Werner Koller und die Skopostheorie das Problem der kulturgebundenen Farbwortvielfalt bei der Übersetzung zu lösen versuchen. Im ersten Teil wird hierfür der Grundstein gelegt, indem interdisziplinäres Wissen auf die Bildung von Farbbezeichnungen, ihrer Herkunft und ihrer biologischen und physikalischen Grundsätze angewendet wird. In diesem Zusammenhang wird auch die Sapir-Whorf-Hypothese diskutiert. Die Etymologie bestehender Farbbezeichnungen verschiedenster Sprachen bildet dabei das Zentrum, sowohl für die Erklärung der Farbwahrnehmung und die Kulturgebundenheit ihrer Bezeichnungen als auch der Neuschöpfung von Farbbezeichnungen in den Übersetzungssituationen. Anhand fiktiver Übersetzungssituationen aus dem Alltag wird der Übersetzungsprozess für jede Übersetzungstheorie simuliert und aus ihrer Sicht verfolgt. Im Abschluss werden die Ergebnisse gegenübergestellt und diskutiert.

Full textAbstract:
Digital Printing has been established as one of the most rapidly evolving printing processes since its first introduction in 1982. In the years that followed, digital printing became the one significant new technology for print media production. Digital printing is continuously changing the print media landscape. Although, DP creates structural changes in production workflow and processes, it lacks in terms of print standardization, compared to offset printing for example, where consistent aim values and guidelines apply by means of ISO 12647-2. This drawback basically depends on two factors, which are interrelated. Firstly, there are many different technologies that are used in digital printing, and, each of them shows substantial difference in printing technology, substrates, data preparation, process control and image quality requirements. Secondly, compared to conventional printing, some digital printing technologies are still developing. After all, digital printing is versatile and variable in every way and cannot be standardized under a single standard. A research on the digital printing technologies, processes and workflows is needed, to determine if a print specifications and quality controls (among them color management), can be applied in Digital Printing, and if possible, to which segment. Since color is very important to printing, especially in packaging and marketing applications, the print evolution demands for matching colors across technologies, substrates, materials and colorants. This paper intends to reveal the present status regarding Digital Printing Standardization. The question posed is whether standards can be applied and in which segments of digital printing either as technology or print sector (commercial decoration, packaging). Within the paper, an analysis of the current industrial typical guidelines ranging from data creation all the way to printing will be made. Guidelines that are determined either by the manufactures of the digital printing machines, or by Institutes, such as FOGRA are reviewed for output process control and colour fidelity. As such, this paper can be regarded as a first attempt to preview the basis where standardization for digital printing processes can be developed.

Full textAbstract:
Chromatic discriminations were measured on two critical axes: one on tritan lines where the excitation level of S-cones varied at fixed L/M cone ratios, and the other along lines radiating from the point (1, 0) in CIE coordinates, in which the L/M ratio varied at fixed S-cone excitation levels. Color discrimination thresholds were measured on a color monitor for 20 starting colors with a dark surround or with an equiluminant white or yellow surround. Discriminations on L/M cone lines were best when the color was near the L/M cone excitation balance and were not affected by S-cone excitation level. The level of L/M cone excitation had no effect on discriminations by S-cones. When the S-cone discriminations were plotted as a function of the S-cone excitation of the starting color, the curve for the dark surround showed a basic TVI template. Discrimination with the yellow or white surrounds was better than discrimination for a dark surround when the S-cone excitation level of the starting color was near that of the surround. A further experiment indicated that S-cone discrimination for the colors whose S-cone excitation level was the same as the white surround was impaired when a gap was introduced between the starting colors and the white surround.

Full textAbstract:
The validation of life predictions of gas turbine engines is usually based on an engine test where the temperature response is measured during a representative mission cycle. A thermal model of the test engine is developed which is then validated by the measured temperature data to within certain datamatch acceptance criteria (steady state and transient) which will provide acceptably accurate predictions of creep life and low-cycle fatigue (LCF). Once the thermal model has been validated, the predicted temperature data are used as boundary conditions for the mechanical (stress) model. This allows the prediction of the fatigue life due to LCF and due to creep. Since it is often almost impossible to validate the mechanical (stress) model by reliable means, it is of great importance to validate the thermal model to within the greatest accuracy possible. Therefore, the tolerances to within which the thermal model is validated has a direct effect on the quality of the predicted life and hence engine reliability. This paper describes the development and implementation of datamatch acceptance criteria (DMAC) for the validation of a thermal model against measured data. The validated thermal model then forms the basis for reliable predictions of the component’s life in terms of LCF and creep. The datamatch acceptance criteria take into account spatial variations of the life-temperature sensitivity as different areas of the rotor are exposed to different temperature gradients and levels. In the following, both life-limiting mechanisms, LCF and creep, will be considered individually. This will result in different datamatch acceptance criteria for steady state and transient conditions, the former relating to creep life and the latter to LCF. The quality of the datamatch is then assessed in terms of a colour code (green/yellow/red) where the various colours represents different levels of acceptance for the thermal model.

Full textAbstract:
The first edition of the Master's Degree in "Color Technology for the Automotive Sector" was held during the last academic year. The academic results in terms of qualifications, achievement and learning were good. In spite of the good sensations, there are aspects to be improved, both in methodology and the development of the subjects, timing of the contents, organization or communication channels. Following this line, the Academic, agreed on a plan of continuous improvement based on the feedback provided by the graduate surveys. A specific survey was carried out to gather their specific experience of the course in order to be able to modify the general strategy of the master's degree at the teaching and organisational level. The objectives were to adapt the teaching methodology to facilitate a more reflexive, participative and autonomous learning with a high degree of involvement and motivation of the students, to improve the academic results in terms of learning and satisfaction, to simplify and improve the logistic management of the course, etc. Thus, the survey included questions relating to the usefulness of the master's degree, methodology, organisation and planning of teaching, as well as a final question relating to the overall satisfaction of the course. A short survey was chosen with only 10 questions that the student rated from 1 to 5 on a scale from "strongly disagree" to "strongly agree". From the analysis of the responses, some important weaknesses were detected, such as the lack of content developed in video format, and the slowness of feedback on the results obtained in the proposed tasks. Based on these results, it was proposed an improvement plan that included the incorporation of videos to teaching materials, flexibility in the deadlines for activities, and the periodic monitoring of student learning and concerns through "Adobe Connect".

There are several terms which describe the Planckian radiation temperature for light sources, including radiance temperature, colour temperature, correlated colour temperature, distribution temperature and ratio temperature. This document provides descriptions of these terms, information on their applicability, and highlights relationships between them so that they may be consistently applied in all applications. Definitions and additional explanatory information for each term are given in this document. Obviously, the greater the difference between the radiation considered and a Planckian radiator, the more tenuous the interpretation of the temperature attribution. Guidelines as to agreed reasonable limits of applicability, if any, are therefore also given, together with information on the calculation of the associated measurement uncertainties where relevant.

Full textAbstract:
In this working paper, I ask whether or not whites could and should write about concerns of People of Color. To this end, I deal with Hannah Arendt’s controversial article “Reflections on Little Rock” from winter 1958/59. In her article, Arendt comments on the de-segregation of black school children in the USA and the associated unrests in Little Rock (Arkansas) and Charlotte (North Carolina) on September 4, 1957. My analysis of her article is initiated by a confrontation of two other texts. In the first, Why I’m No Longer Talking to White People About Race Reni Eddo-Lodge argues that white people are not able to understand the point of view of people of color. In the second, On Kant’s Political Philosophy Hannah Arendt advocates for the contrary that people can understand each other’s point of view when training their imagination to take visits. Since Arendt’s “Reflections on Little Rock” is considered to be a failure, especially in regards of grasping the problems of people of color in the USA, my general question is whether Eddo-Lodge is right, and whether there is no understanding possible or if Arendt missed a crucial step in her own attempt to go visiting? To clarify this, my analysis focuses on Arendt’s use of the term “discrimination”.

Full textAbstract:
The objectives of this project were to develop procedures and models, based on neural networks, for quality sorting of agricultural produce. Two research teams, one in Purdue University and the other in Israel, coordinated their research efforts on different aspects of each objective utilizing both melons and tomatoes as case studies. At Purdue: An expert system was developed to measure variances in human grading. Data were acquired from eight sensors: vision, two firmness sensors (destructive and nondestructive), chlorophyll from fluorescence, color sensor, electronic sniffer for odor detection, refractometer and a scale (mass). Data were analyzed and provided input for five classification models. Chlorophyll from fluorescence was found to give the best estimation for ripeness stage while the combination of machine vision and firmness from impact performed best for quality sorting. A new algorithm was developed to estimate and minimize training size for supervised classification. A new criteria was established to choose a training set such that a recurrent auto-associative memory neural network is stabilized. Moreover, this method provides for rapid and accurate updating of the classifier over growing seasons, production environments and cultivars. Different classification approaches (parametric and non-parametric) for grading were examined. Statistical methods were found to be as accurate as neural networks in grading. Classification models by voting did not enhance the classification significantly. A hybrid model that incorporated heuristic rules and either a numerical classifier or neural network was found to be superior in classification accuracy with half the required processing of solely the numerical classifier or neural network. In Israel: A multi-sensing approach utilizing non-destructive sensors was developed. Shape, color, stem identification, surface defects and bruises were measured using a color image processing system. Flavor parameters (sugar, acidity, volatiles) and ripeness were measured using a near-infrared system and an electronic sniffer. Mechanical properties were measured using three sensors: drop impact, resonance frequency and cyclic deformation. Classification algorithms for quality sorting of fruit based on multi-sensory data were developed and implemented. The algorithms included a dynamic artificial neural network, a back propagation neural network and multiple linear regression. Results indicated that classification based on multiple sensors may be applied in real-time sorting and can improve overall classification. Advanced image processing algorithms were developed for shape determination, bruise and stem identification and general color and color homogeneity. An unsupervised method was developed to extract necessary vision features. The primary advantage of the algorithms developed is their ability to learn to determine the visual quality of almost any fruit or vegetable with no need for specific modification and no a-priori knowledge. Moreover, since there is no assumption as to the type of blemish to be characterized, the algorithm is capable of distinguishing between stems and bruises. This enables sorting of fruit without knowing the fruits' orientation. A new algorithm for on-line clustering of data was developed. The algorithm's adaptability is designed to overcome some of the difficulties encountered when incrementally clustering sparse data and preserves information even with memory constraints. Large quantities of data (many images) of high dimensionality (due to multiple sensors) and new information arriving incrementally (a function of the temporal dynamics of any natural process) can now be processed. Furhermore, since the learning is done on-line, it can be implemented in real-time. The methodology developed was tested to determine external quality of tomatoes based on visual information. An improved model for color sorting which is stable and does not require recalibration for each season was developed for color determination. Excellent classification results were obtained for both color and firmness classification. Results indicted that maturity classification can be obtained using a drop-impact and a vision sensor in order to predict the storability and marketing of harvested fruits. In conclusion: We have been able to define quantitatively the critical parameters in the quality sorting and grading of both fresh market cantaloupes and tomatoes. We have been able to accomplish this using nondestructive measurements and in a manner consistent with expert human grading and in accordance with market acceptance. This research constructed and used large databases of both commodities, for comparative evaluation and optimization of expert system, statistical and/or neural network models. The models developed in this research were successfully tested, and should be applicable to a wide range of other fruits and vegetables. These findings are valuable for the development of on-line grading and sorting of agricultural produce through the incorporation of multiple measurement inputs that rapidly define quality in an automated manner, and in a manner consistent with the human graders and inspectors.

Full textAbstract:
Global climate change and warming temperatures represent the greatest future challenge for global food production and quality. In this project, we will define the genetic factors of climate-associated taste deficiencies in carrot. Carrot is considered one of the leading horticultural crops in the world in terms of its nutritional value, health benefits, and unique flavor based on its high content of carotenoids and volatile aroma compounds. In recent years, carrot genotypes of different color with improved nutraceutical attributes have been developed. When exposed to high growth temperatures, carrots develop an undesired harsh and bitter taste caused by the accumulation of terpene metabolites. This taste deficiency represents a quality defect to carrot breeders and large- scale growers and needs to be minimized for successful marketing of carrot crops. Surprisingly, the genetic determinants of bitter and harsh flavor in carrot and their response to temperature stress are not well characterized. We started to elucidate these factors in different carrot cultivars by investigating the biosynthesis of volatile terpenes, which represent the predominant flavor compounds in carrots. Also, up to date we identified and characterized two terpenesynthase enzymes, one of which produces (E)-β- caryophyllene, a major terpene component in carrot root. Both TPSs may contribute to the observed variation in volatile terpene formation.

Full textAbstract:
Objectives. To evaluate the effectiveness and comparative effectiveness of opioid, nonopioid pharmacologic, and nonpharmacologic therapy in patients with specific types of acute pain, including effects on pain, function, quality of life, adverse events, and long-term use of opioids. Data sources. Electronic databases (Ovid® MEDLINE®, PsycINFO®, Embase®, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews) to August 2020, reference lists, and a Federal Register notice. Review methods. Using predefined criteria and dual review, we selected randomized controlled trials (RCTs) of outpatient therapies for eight acute pain conditions: low back pain, neck pain, other musculoskeletal pain, neuropathic pain, postoperative pain following discharge, dental pain (surgical or nonsurgical), pain due to kidney stones, and pain due to sickle cell disease. Meta-analyses were conducted on pharmacologic therapy for dental pain and kidney stone pain, and likelihood of repeat or rescue medication use and adverse events. The magnitude of effects was classified as small, moderate, or large using previously defined criteria, and strength of evidence was assessed. Results. One hundred eighty-three RCTs on the comparative effectiveness of therapies for acute pain were included. Opioid therapy was probably less effective than nonsteroidal anti-inflammatory drugs (NSAIDs) for surgical dental pain and kidney stones, and might be similarly effective as NSAIDs for low back pain. Opioids and NSAIDs were more effective than acetaminophen for surgical dental pain, but opioids were less effective than acetaminophen for kidney stone pain. For postoperative pain, opioids were associated with increased likelihood of repeat or rescue analgesic use, but effects on pain intensity were inconsistent. Being prescribed an opioid for acute low back pain or postoperative pain was associated with increased likelihood of use of opioids at long-term followup versus not being prescribed, based on observational studies. Heat therapy was probably effective for acute low back pain, spinal manipulation might be effective for acute back pain with radiculopathy, acupressure might be effective for acute musculoskeletal pain, an opioid might be effective for acute neuropathic pain, massage might be effective for some types of postoperative pain, and a cervical collar or exercise might be effective for acute neck pain with radiculopathy. Most studies had methodological limitations. Effect sizes were primarily small to moderate for pain, the most commonly evaluated outcome. Opioids were associated with increased risk of short-term adverse events versus NSAIDs or acetaminophen, including any adverse event, nausea, dizziness, and somnolence. Serious adverse events were uncommon for all interventions, but studies were not designed to assess risk of overdose, opioid use disorder, or long-term harms. Evidence on how benefits or harms varied in subgroups was lacking. Conclusions. Opioid therapy was associated with decreased or similar effectiveness as an NSAID for some acute pain conditions, but with increased risk of short-term adverse events. Evidence on nonpharmacological therapies was limited, but heat therapy, spinal manipulation, massage, acupuncture, acupressure, a cervical collar, and exercise were effective for specific acute pain conditions. Research is needed to determine the comparative effectiveness of therapies for sickle cell pain, acute neuropathic pain, neck pain, and management of postoperative pain following discharge; effects of therapies for acute pain on non-pain outcomes; effects of therapies on long-term outcomes, including long-term opioid use; and how benefits and harms of therapies vary in subgroups.

Full textAbstract:
Plants adjust their growth and development in a manner optimal for the prevailing light conditions. The molecular mechanisms by which light signals are transduced and integrated with other environmental and developmental signals are an area of intense research. (Batschauer, 1999; Quail, 2002) One paradigm emerging from this work is the interconnectedness of discrete physiological responses at the biochemical level, for instance, between auxin and light signaling (Colon-Carmona et al., 2000; Schwechheimer and Deng, 2001; Tian and Reed, 1999) and between light signaling and plant pathogen interactions (Azevedo et al., 2002; Liu et al., 2002). The COP9 signalosome (CSN) protein complex has a central role in the light control of plant development. Arabidopsis mutants that lack this complex develop photomorphogenically even in the absence of light signals (reviewed in (Karniol and Chamovitz, 2000; Schwechheimer and Deng, 2001). Thus the CSN was hypothesized to be a master repressor of photomorphogenesis in darkness, and light acts to bypass or eliminate this repression. However, the CSN regulates more than just photomorphogenesis as all mutants lacking this complex die near the end of seedling development. Moreover, an essentially identical complex was subsequently discovered in animals and yeast, organisms whose development is not light responsive, exemplifying how plant science can lead the way to exciting discoveries in biomedical model species (Chamovitz and Deng, 1995; Freilich et al., 1999; Maytal-Kivity et al., 2002; Mundt et al., 1999; Seeger et al., 1998; Wei et al., 1998). Our long-term objective is to determine mechanistically how the CSN controls plant development. We previously that this complex contains eight subunits (Karniol et al., 1998; Serino et al., 1999) and that the 27 ilia subunit is encoded by the FUS5/CSN7 locus (Karniol et al., 1999). The CSN7 subunit also has a role extraneous to the COP9 signalosome, and differential kinase activity has been implicated in regulating CSN7 and the COP9 signalosome (Karniol et al., 1999). In the present research, we further analyzed CSN7, both in terms of interacting proteins and in terms of kinases that act on CSN7. Furthermore we completed our analysis of the CSN in Arabidopsis by analyzing the remaining subunits. Outline of Original Objectives and Subsequent Modifications The general goal of the proposed research was to study the CSN7 (FUS5) subunit of the COP9 signalosome. To this end we specifically intended to: 1. Identify the residues of CSN7 that are phosphorylated. 2. Monitor the phosphorylation of CSN7 under different environmental conditions and under different genetic backgrounds. 3. Generate transgenic plants with altered CSN7 phosphorylation sites. 4. Purify CSN7 kinase from cauliflower. 5. Clone the Arabidopsis cDNA encoding CSN7 kinase 6. Isolate and characterize additional CSN7 interacting proteins. 7. Characterize the interaction of CSN7 and the COP9 signalosome with the HY5-COP1 transcriptional complex. Throughout the course of the research, emphasis shifted from studying CSN7 phosphorylation (Goals 1-3), to studying the CSN7 kinase (Goal 4 and 5), an in depth analysis of CSN7 interactions (Goal 6), and the study of additional CSN subunits. Goal 7 was also abandoned as no data was found to support this interaction.

United States Department of Agriculture, November 2014. http://dx.doi.org/10.32747/2014.7699855.bard.
Full textAbstract:
Original objectivesThe objectives of this project were to evaluate the growth performance, meat yield and quality attributes of broiler strains widely differing in their genetic potential under normal temperature vs. warm temperature (short and long-term) conditions. Strain differences in breast muscle accretion rate, metabolic responses under heat load and, gross and histopathological changes in breast muscle under thermal load was also to be characterized. BackgroundTremendous genetic progress has been made in broiler chicken growth rate and meat yield since the 1950s. Higher growth rate is driven by higher rates of feed intake and metabolism, resulting in elevated internal heat production. Hot rearing conditions negatively affect broiler growth by hindering dissipation of heat and may lead to a lethal elevation in body temperature. To avoid heat-induced mortality, broilers reduce feed intake, leading to depressed growth rate, lower weight gain, reduce breast meat yield and quality. Thus, the genetic potential of contemporary commercial broilers (CCB) is not fully expressed under hot conditions. Major conclusions, solutions, and achievementsResearch conducted in Israel focused on three broiler strains – CCB, Featherless, Feathered sibs (i.e., sharing similar genetic background). Complimentary research trials conducted at Auburn utilized CCB (Cobb 500, Cobb 700, Ross 308, Ross 708), contrasting their performance to slow growing strains. Warm rearing conditions consistently reduced feed intake, growth rate, feed efficiency, body weight uniformity and breast muscle yield, especially pronounced with CCB and magnified with age. Breast meat quality was also negatively affected, as measured by higher drip loss and paler meat color. Exposure to continuous or short-term heat stress induced respiratory alkalosis. Breast muscle histomorphometrics confirmed enhanced myofiber hypertrophy in CCB. Featherless broilers exhibited a significant increase in blood-vessel density under warm conditions. Rapid growth and muscle accretion rate was correlated to various myopathies (white striping, woody and necrotic) as well as to increases in plasma creatinekinase levels. Whether the trigger(s) of muscle damage is loss of cellular membrane integrity due to oxidative damage or tissue lactate accumulation, or to loss of inter-compartmental cation homeostasis is yet to be determined. Based on genome-wide single-nucleotide polymorphism array genotyping, identification of the gene with the recessive mutation Scaleless (sc) facilitated the development a dCAPS assay to discriminate between sc carrier (sc/+) and non-carrier (+/+) individuals. ImplicationsThis project confirmed that featherless broiler strains grow efficiently with high yield and quality of breast meat, even under warm rearing conditions that significantly depress the overall performance of CCB. Therefore, broiler meat production in hot regions and climates can be substantially improved by introducing the featherless gene into contemporary commercial broiler stocks. This approach has become more feasible with the development of dCAPS assay. A novel modification of the PCR protocol (using whole blood samples instead of extracted DNA) may contribute to the efficient development of commercial featherless broiler strains. Such strains will allow expansion of the broiler meat production in developing countries in warm climates, where energy intensive environmental control of rearing facilities are not economical and easily achievable.

Full textAbstract:
Objectives: The Israeli work plan regarding HBTM included: (a) producing a better diagnostic method; (b) following infestations during the season and evaluating damage to resistant bees and, (c) controlling HBTM by conventional means under local conditions. For varroa our plans to try novel control (e.g. oil novel control (e.g. oil patties & essential oils) were initially delayed by very low pest populations, then disrupted by the emergence of fluvalinate resistance. We monitored the spread of resistance to understand it better, and analyzed an underlying biochemical resistance mechanism in varroa. The US work plan focused on novel management methods for both mites with an emphasis on reducing use of traditional insecticides due to resistance and contamination issues. Objectives were: (a) evaluating plant essential oils for varroa control; (b) exploring the vulnerability of varroa to desiccation for their management; and (c) looking for biological variation in HBTM that could explain virulence variability between colonies. Although the initial PI at the USDA Beltsville Bee Lab, W.A. Bruce, retired during the project we made significant strides especially on varroa water balance. Subcontracts were performed by Yoder (Illinois College) on varroa water balance and DeGrandi-Hoffman (USDA) who evaluated plant essential oils for their potential to control varroa. We devised an IPM strategy for mite control i the U.S. Background: Mites that parasitize honey bees are a global problem. They are threatening the survival of managed and feral bees, the well-being of commercial/hobby beekeeping, and due to pollination, the future of some agricultural commodities is threatened. Specific economic consequences of these mites are that: (a) apiculture/breeder business are failing; (b) fewer colonies exist; (c) demand and cost for hive leasing are growing; (d) incidences of bee pathogens are increasing; and, (e) there are ore problems with commercial-reared bees. As a reflection of the continued significance f bee mites, a mite book is now in press (Webster & delaplane, 2000); and the 2nd International Conference on Africanized Honey Bees and Bee Mites is scheduled (April, 2000, Arizona). The first such conference was at OSU (1987, GRN was co-organizer). The major challenge is controlling two very different mites within a colony while not adversely impacting the hive. Colony management practices vary, as do the laws dictating acaricide use. Our basic postulates were that: (a) both mites are of economic importance with moderate to high infestations but not at low rates and, (b) once established they will not be eradicated. A novel strategy was devised that deals with the pests concomitantly by maintaining populations at low levels, without unnecessary recourse to synthetic acaricides. Major Conclusions, Solutions, Achievements: A major recent revelation is that there are several species of "Varroa jacobsoni" (Anderson & Trueman 1999). Work on control, resistance, population dynamics, and virulence awaits knowing whether this is a problem. In the U.S. there was no difference between varroa from three locales in terms of water balance parameters (AZ, MN & PA), which bodes well for our work to date. Winter varroa (U.S.) were more prone to desiccation than during other seasons. Varroa sensitivity to desiccation has important implications for improving IPM. Several botanicals showed some promise for varroa control (thymol & origanum). Unfortunately there is varroa resistance to Apistan in Israel but a resistance mechanism was detected for the first time. The Israel team also has a new method for HBTM diagnosis. Annual tracheal mite population trends in Israel were characterized, which will help in targeting treatment. Effects of HBTM on honey yields were shown. HBTM control by Amitraz was demonstrated for at least 6 months. Showing partial resistance by Buckfast bees to HBTM will be an important IPM tactic in Israel and U.S.

The worldwide market for ornamental saltwater invertebrates supplies the needs of millions of aquarium hobbyists, public exhibitions (i.e., zoos) universities and research institutions. With respect to reef building corals, it is estimated that more than half a million coral colonies/year from a total 93 genera, were exported globally during the period of 1985-1997. International value of retail sale of live coral trade alone is estimated as $78 million in 1997 (not including the illegally, widely smuggled material). The continuous, large-scale collection of marine organisms is responsible, in many places, for the destruction of coral reefs. The expected expansion of the trade further threatens these fragile habitats. While no true captive-bred corals are commercially available, our long-term goal is to develop ex situ inland farming of coral colonies that will circumvent the need for in situ collections and will provide domesticated specimens for the trade and for research. We simultaneously studied two model branching coral species, Stylophora pistillata (Pocilloporidae; in Israel) and Porites (Poritidae; in the US). The proposal included three specific aims: (a) To develop protocols for nubbins (small fragments, down to the size of a single polyp) usage in coral farming;(b) To address the significance of colony pattern formation to the coral trade; and (c) To develop the protocols of using nubbins in physiological and ecotoxicological assays (using oil dispersants, the expression of the stress protein HSP-70, household detergents, etc.). Ten scientific publications (published manuscripts, accepted for publications, submitted to scientific journals, in preparation), revealing results that were related to all three specific aims, originated from this BARD proposal. As a result of the work supported by the BARD, we have now, in hand, original and improved protocols for coral maintenance ex situ, proven expertise on manipulating coral colonies’ pattern formation and biological knowledge on island mariculture of reef corals (from Hawaii and from the Red Sea) amenable for the ornamental trade (for public and private aquaria use, for experimentation). At least one Israeli company (Red Sea Corals, Ltd., KibbutzSaar) is using our methodologies for further developing this new mariculture sector. We are now in the process of introducing the rationale and methodologies to Hawaiian private entities to expand dissemination of the research outcomes.

Commercial agriculture has come under increasing pressure to reduce nitrogen fertilizer inputs in order to minimize potential nonpoint source pollution of ground and surface waters. This has resulted in increased interest in site specific fertilizer management. One way to solve pollution problems would be to determine crop nutrient needs in real time, using remote detection, and regulating fertilizer dispensed by an applicator. By detecting actual plant needs, only the additional nitrogen necessary to optimize production would be supplied. This research aimed to develop techniques for real time assessment of nitrogen status of corn using a mobile sensor with the potential to regulate nitrogen application based on data from that sensor. Specifically, the research first attempted to determine the system parameters necessary to optimize reflectance spectra of corn plants as a function of growth stage, chlorophyll and nitrogen status. In addition to that, an adaptable, multispectral sensor and the signal processing algorithm to provide real time, in-field assessment of corn nitrogen status was developed. Spectral characteristics of corn leaves reflectance were investigated in order to estimate the nitrogen status of the plants, using a commercial laboratory spectrometer. Statistical models relating leaf N and reflectance spectra were developed for both greenhouse and field plots. A basis was established for assessing nitrogen status using spectral reflectance from plant canopies. The combined effect of variety and N treatment was studied by measuring the reflectance of three varieties of different leaf characteristic color and five different N treatments. The variety effect on the reflectance at 552 nm was not significant (a = 0.01), while canonical discriminant analysis showed promising results for distinguishing different variety and N treatment, using spectral reflectance. Ambient illumination was found inappropriate for reliable, one-beam spectral reflectance measurement of the plants canopy due to the strong spectral lines of sunlight. Therefore, artificial light was consequently used. For in-field N status measurement, a dark chamber was constructed, to include the sensor, along with artificial illumination. Two different approaches were tested (i) use of spatially scattered artificial light, and (ii) use of collimated artificial light beam. It was found that the collimated beam along with a proper design of the sensor-beam geometry yielded the best results in terms of reducing the noise due to variable background, and maintaining the same distance from the sensor to the sample point of the canopy. A multispectral sensor assembly, based on a linear variable filter was designed, constructed and tested. The sensor assembly combined two sensors to cover the range of 400 to 1100 nm, a mounting frame, and a field data acquisition system. Using the mobile dark chamber and the developed sensor, as well as an off-the-shelf sensor, in- field nitrogen status of the plants canopy was measured. Statistical analysis of the acquired in-field data showed that the nitrogen status of the com leaves can be predicted with a SEP (Standard Error of Prediction) of 0.27%. The stage of maturity of the crop affected the relationship between the reflectance spectrum and the nitrogen status of the leaves. Specifically, the best prediction results were obtained when a separate model was used for each maturity stage. In-field assessment of the nitrogen status of corn leaves was successfully carried out by non contact measurement of the reflectance spectrum. This technology is now mature to be incorporated in field implements for on-line control of fertilizer application.
