Is Computer Ethics Unique?

The rise of various unique, or uniquely transformed, ethical issues supports the claim that computer ethics deserves to be regarded as an academic field in its own right. Some of these issues are unique because they inherit the unique properties of the technology that generates or transforms them. When we are unable to resolve these issues through non-computer moral analogies, we are forced to discover new moral values, formulate new moral principles and develop new policies

La yuca en la alimentacion de cerdos

Research results obtained by the Cassava and Swine programs at the Instituto Colombiano Agropecuario are discussed. Low HCN var. should be used for swine feeding; the most promising var. is Llanera, which can yield 78 t/ha/10 mo and has a high crude protein content (7.25 percent). Balanced diets using the fresh roots or meal + different protein supplements are given for the life cycle of the swine: gestation, lactation, growing and finishing periods. When using CM, molasses should be added to make it more acceptable to the pigs; fresh roots should be supplied on a daily basis since they ferment rapidly. (CIAT

Performing and sounding disruption : coded pleasure in Jay-Z and Kanye West’s “Otis”

textFrom minstrelsy to hip-hop, the black performer has always been entangled in a complex network of branding, packaging, and promotion. The black body is cultural capital and in hip-hop, the black thug and his dangerous body are the fetishized objects of desire. Despite these exploitative constraints, artists find spaces to enact what little resistance is possible. In the following report, I perform a close reading and close listening of Jay-Z and Kanye West’s “Otis.” Paying particular attention to the intersections of the visual and the aural, I find that Jay-Z and West encode desire, pleasure, and imagination beneath boastful rhymes and material opulence. Jay-Z and West adopt American symbols of prosperity and freedom and, in disruptive fashion, resignify black masculinity in the cultural imagination. Soul sound, as intoned through Otis Redding and James Brown, lends a politics of brotherhood and radicalism to Jay-Z and West’s articulation of affective black masculinity. I employ a collage-like network of theoretical frames that span performance, sound, and literary theory to trace how race and gender performance codes a discourse of disruption. I find that “Otis” is a type a blueprint—an instruction manual for youth of color to deconstruct, innovate, and feel deeply. Through linguistic and performative codes, Jay-Z and West create a safe space, a cipher for men of color to desire and, in turn, experience pleasure. I trace how Jay-Z and West move closer to a practice of hip-hop feminism and, in a field notorious for rampant homophobia, misogyny, and violence—that’s remarkable.Englis

Yield models, components, and interrelationships in upland cotton, Gossypium hirsutum L

Studies were carried out to develop yield models for selected Upland cotton genotypes to determine the interrelations of yield components and their relative contributions to cotton yield. Data used in these investigations were collected in 1968 and 1969 by the cotton breeding and quality investigations program, Pee Dee Experiment Station, Florence, South Carolina. This yield model study utilized four selected genotypes both individually and collectively, in equating yield to the volume of a rectangular parallelepiped. Axes (X), (Y), and (Z) of the geo-metric model represented the equivalent number of bolls per square meter, the equivalent number of seeds per boll, and the weight of seed cotton per seed, respectively. The results indicated that the primary gain in yield improvement would be made by exerting selection pressure on the number of bolls per unit area. Concurrent selection pressure should also be placed on the number of seeds per boll and weight of seed cotton per seed in order to maintain these components at acceptable levels. Data collected for the yield components in each test entry across 13 locations in 1968, 12 locations in 1969, and 25 locations in 1968-1969 combined, were used to calculate simple correlation coefficients between components. These analyses permitted comparisons of the within years results with those obtained when additional component variations were introduced. These analyses indicated that cause and effect relationships were involved between many of the component pairs. These studies indicated that a large population includ-ing several environments would be necessary for drawing conclusions about component relationships. Multiple regression analyses were used to determine the relative contributions of the components to lint yield, and to rank them in order of importance. The number of bolls per unit area accounted for 81 to 91% of the total lint yield variation. Boll size contri-buted 6 to 14% and seed weight in grams per 100 bolls 2 to 4% to the total lint yield variation. The remaining components increased the araltiple correlation only .0002 to .0004 in those analyses. The total multiple correlation coefficient was .99 in all cases

Does Being Attractive Always Help? Positive and Negative Effects of Attractiveness on Social Decision Making

Previous studies of organizational decision making demonstrate an abundance of positive biases directed toward highly attractive individuals. The current research, in contrast, suggests that when the person being evaluated is of the same sex as the evaluator, attractiveness hurts, rather than helps. Three experiments assessing evaluations of potential job candidates (Studies 1 and 3) and university applicants (Study 2) demonstrated positive biases toward highly attractive other-sex targets but negative biases toward highly attractive same-sex targets. This pattern was mediated by variability in participants’ desire to interact with versus avoid the target individual (Studies 1 and 2) and was moderated by participants’ level of self-esteem (Study 3); the derogation of attractive same-sex targets was not observed among people with high self-esteem. Findings demonstrate an important exception to the positive effects of attractiveness in organizational settings and suggest that negative responses to attractive same-sex targets stem from perceptions of self-threat

High Status Men (But Not Women) Capture the Eye of the Beholder

Two studies tested the hypothesis that people attend preferentially to high status men (but not women). Participants overestimated the frequency of high status men in rapidly presented arrays (Experiment 1) and fixated their visual attention on high status men in an eye-tracking study (Experiment 2). Neither study showed any evidence of preferential attention to high status women, but there was evidence that physically attractive women captured attention. The results from both studies support evolutionary theories regarding differential prioritization of social status and physical attractiveness in men versus women. These findings illustrate how examination of early-in-the-stream social cognition can provide useful insights into the adapted mind
