This book looks in particular at Achebe's Anthills of the Savannah and Petals of Blood by Ngugi wa Thiong'o, but situates these within the broader context of developments in African literature over the past half-century, discussing writers from Ayi Kwei Armah to Wole Soyinka. M.S.C. Okolo provides a thorough analysis of the authors' differing approaches and how these emerge from the literature. Okolo argues that these authors have been profoundly affected by the political situation of Africa, but have also helped (...) to create a new African political philosophy. (shrink)

L'omniprésence de l'image dans nos sociétés contemporaines, massivement régies par les médias visuels, - photographie, cinéma, télévision, internet - a bouleversé notre culture, longtemps fondée sur le primat de l'écrit. Cette révolution renoue cependant avec les assises les plus anciennes de notre culture où l'image, prise en charge par la peinture, le théâtre et les arts oratoires, était porteuse de savoir et d'émotion esthétique. Ce pouvoir de création et de communication de l'image a fait très tôt l'objet d'un examen critique (...) soucieux d'en dénoncer les dangers : force et forme d'attraction paroxystique, la fascination désigne assez bien ce péril et ces pièges. Platon, le premier, en instruit le procès tandis qu'Aristote s'efforce d'arrimer au logos la puissance imageante du théâtre. A l'âge classique, les Etats modernes établissent leur pouvoir par un contrôle croissant de l'image : J-M Apostolidès et L Marin ont rendu compte, pour la France, de la machinerie fascinatrice du "grand Roi", qui traverse les arts et l'imaginaire classiques. La littérature contemporaine inclut dans sa démarche réflexive cette méditation sur le pouvoir fascinant de l'image : l'oeuvre de Pascal Quignard en reprend et repense ainsi les figures paradigmatiques - Narcisse, Méduse, Médée. Examinant ce phénomène dans la peinture, la littérature et les arts du spectacle, cet ouvrage, transhistorique et pluridisciplinaire, est l'occasion d'un dialogue entre philosophes, littéraires, esthéticiens et historiens qui interrogent ici collectivement, en toute liberté critique, la fascination des images dans son ambivalence, rayonnante et aliénante.

The study ascertained (1) whether an observer's scope of justice with reference to either the moral agent or the target person of a moral act, would affect his/her judgements of the ethicality of the act, and (2) whether observer judgements of ethicality parallel the moral agent's decision processes in systematically evaluating the intensity of the moral issue. A scenario approach was used. Results affirmed both research questions. Discussions covered the implications of the findings for the underlying cognitive processes of moral (...) judgements, for the link between judgements of fairness and ethicality, as well as for the debate of ethical absolutism versus relativism.

The music ensemble has often been used as an analogy of organisation processes in general. Many versions of this analogy presuppose a specific organisation structure in the ensemble with clearly defined leader-follower relationships from which we can learn important points about successful leadership. This paper wishes to draw attention to the wide variety of organisation processes that may occur in a music ensemble, some of which are not dependent on leadership. Through the outlines of a logical analysis of a coordination (...) problem, it is argued that the music performance is in fact exemplary of a situation in which individual dedication to a goal promotes coordination in the entire group.

Buildings are constructed for accommodating living and industrial needs. Floor cleaning robots have been developed to cater to the demand of these buildings. Area coverage and coverage time are crucial performance factors of a floor cleaning robot. Reconfigurable tiling robots have been introduced over fixed shape robots to improve area coverage in floor cleaning applications compared to robots with fixed morphologies. However, area coverage and coverage time of a tiling robot compromised one another. This study proposes a novel concept that (...) considers the ability of a tiling robot to configure both its morphology and size according to the environment. This concept is inspired by the pleomorphism that could be seen in bacteria. In this regard, P-hTetro, a pleomorphic tiling robot that can reconfigure its morphology and size, is considered. A novel coverage strategy for realizing the size reconfiguration is also proposed. According to this strategy, the robot covers obstacle-free areas with its maximum size, while an obstacle cluster is covered after shrinking to an optimum size. The optimum size for reconfiguration is determined by the genetic algorithm based on the arrangement of the environment. The performance and behavior of the proposed P-hTetro have been compared against that of an existing tiling robot which has a fixed size. According to the statistical outcomes, a tiling robot with the ability to reconfigure its size can significantly improve the performance in the aspects of area coverage and coverage time compared to a tiling robot with no ability to reconfigure its size.

A total of 1918 loci, detected by the hybridization of 938 expressed sequence tag unigenes from 26 Triticeae cDNA libraries, were mapped to wheat homoeologous group 4 chromosomes using a set of deletion, ditelosomic, and nulli-tetrasomic lines. The 1918 EST loci were not distributed uniformly among the three group 4 chromosomes; 41, 28, and 31% mapped to chromosomes 4A, 4B, and 4D, respectively. This pattern is in contrast to the cumulative results of EST mapping in all homoeologous groups, as reported (...) elsewhere, that found the highest proportion of loci mapped to the B genome. Sixty-five percent of these 1918 loci mapped to the long arms of homoeologous group 4 chromosomes, while 35% mapped to the short arms. The distal regions of chromosome arms showed higher numbers of loci than the proximal regions, with the exception of 4DL. This study confirmed the complex structure of chromosome 4A that contains two reciprocal translocations and two inversions, previously identified. An additional inversion in the centromeric region of 4A was revealed. A consensus map for homoeologous group 4 was developed from 119 ESTs unique to group 4. Forty-nine percent of these ESTs were found to be homoologous to sequences on rice chromosome 3, 12% had matches with sequences on other rice chromosomes, and 39% had no matches with rice sequences at all. Limited homology was found between wheat ESTs on homoeologous group 4 and the Arabidopsis genome. Forty-two percent of the homoeologous group 4 ESTs could be classified into functional categories on the basis of blastX searches against all protein databases. (shrink)

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)

Sacrifice haunts the Phaedo. In this article, I argue that the mise-en-scène of the death scene of the Phaedo, as well as other sacrificial elements in the background of the dialogue, creates a nexus that positively integrates the birth, philosophical practice, and death of Socrates into the ritualized rhythm of the life of the city of Athens. A close reading of the death scene presented as a synopsis with Walter Burkert’s well-known analysis of Greek sacrifice reveals convergences and divergences between (...) the Phaedo and Greek sacrificial practice. Socrates appears as a willing victim who accepts the city’s sacrificial practice while remaining on his own terms. (shrink)

Background: Black, Asian and minority ethnic groups have a high need for organ transplantation but deceased donation is low. This restricts the availability of well-matched organs and results in relatively long waiting times for transplantation, with increased mortality risks. Objective: To identify barriers to organ donor registration and family consent among the BAME population, and to develop and evaluate a training intervention to enhance communication with ethnic minority families and identify impacts on family consent. Methods: Three-phase programme comprising community-based research (...) involving two systematic reviews examining attitudes and barriers to organ donation and effective interventions followed by 22 focus groups with minority ethnic groups; hospital-based research examining staff practices and influences on family consent through ethics discussion groups with staff, a study on intensive care units and interviews with bereaved ethnic minority families; and development and evaluation of a training package to enhance cultural competence among ICU staff. Setting: Community focus group study in eight London boroughs with high prevalence of ethnic minority populations. Hospital studies at five NHS hospital trusts. Participants: Community studies: 228 focus group participants; hospital studies: 35 nurses, 28 clinicians, 19 hospital chaplains, 25 members of local Organ Donation Committees, 17 bereaved family members; and evaluation: 66 health professionals. Data sources: Focus groups with community residents, systematic reviews, qualitative interviews and observation in ICUs, EDGs with ICU staff, bereaved family interviews and questionnaires for trial evaluation. Review methods: Systematic review and narrative synthesis. Results: Community studies: Organ Donor Register – different ethnic/faith and age groups were at varying points on the ‘pathway’ to organ donor registration, with large numbers lacking knowledge and remaining at a pre-contemplation stage. Key attitudinal barriers were uncertainties regarding religious permissibility, bodily concerns, lack of trust in health professionals and little priority given to registration, with the varying significance of these factors varying by ethnicity/faith and age. National campaigns focusing on ethnic minorities have had limited impact, whereas characteristics of effective educational interventions are being conducted in a familiar environment; addressing the groups’ particular concerns; delivery by trained members of the lay community; and providing immediate access to registration. Interventions are also required to target those at specific stages of the donation pathway. Hospital studies: family consent to donation – many ICU staff, especially junior nurses, described a lack of confidence in communication and supporting ethnic minority families, often reflecting differences in emotional expression, faith and cultural beliefs, and language difficulties. The continuing high proportion of family donation discussions that take place without the collaboration of a specialist nurse for organ donation reflected consultants’ views of their own role in family consent to donation, a lack of trust in SNODs and uncertainties surrounding controlled donations after circulatory death. Hospital chaplains differed in their involvement in ICUs, reflecting their availability/employment status, personal interests and the practices of ICU staff. Evaluation: professional development package – a digital versatile disk-based training package was developed to promote confidence and skills in cross-cultural communication. Initial evaluation produced positive feedback and significant affirmative attitudinal change but no significant difference in consent rate over the short follow-up period with requirements for longer-term evaluation. Limitations: Participants in the focus group study were mainly first-generation migrants of manual socioeconomic groups. It was not permitted to identify non-consenting families for interview with data regarding the consent process were therefore limited to consenting families. Conclusions: The research presents guidance for the effective targeting of donation campaigns focusing on minority ethnic groups and provides the first training package in cultural competence in the NHS. Future work: Greater evaluation is required of community interventions in the UK to enhance knowledge of effective practice and analysis of the experiences of non-consenting ethnic minority families.

Although it is common in liberal and progressive circles to scoff at the idea that the Unites States is “exceptional”—a derision driven by an admirable suspicion of the chauvinistic connotations of the exceptionalist view—doing so obscures a significant reality. The United States is different, or at least rather unusual, in its social, cultural, and geo-strategic circumstances, especially when compared to the nations of Europe from which it draws the core of its intellectual traditions. What's more, the critique of American exceptionalism (...) has acquired its own troublesome politics. “It is extremely dangerous to encourage people to see themselves as exceptional, whatever….

Historically the emergence of a precise technical meaning for probability, as distinct from its vague popular useage, has taken time; and confusion still arises from the concept of probability having different meanings in different flelds of discourse. Its technical meaning and appropriate rules are surveyed in the flelds of logic , mathematics , and science , and the relation between these three aspects of probability theory discussed. ‐. M. S.

Task unrelated thought (TUT) refers to thought directed away from the current situation, for example a daydream. Three experiments were conducted on healthy participants, with two broad aims. First, to contrast distributed and encapsulated views of cognition by comparing the encoding of categorical and random lists of words (Experiments One and Two). Second, to examine the consequences of experiencing TUT during study on the subsequent retrieval of information (Experiments One, Two, and Three). Experiments One and Two demonstrated lower levels of (...) TUT and higher levels of word-fragment completion whilst encoding categorical relative to random stimuli, supporting the role of a distributed resource in the maintenance of TUT. In addition the results of all three experiments suggested that experiencing TUT during study had a measurable effect on subsequent retrieval. TUT was associated with increased frequency of false alarms at retrieval (Experiment One). In the subsequent experiments TUT was associated with no advantage to retrieval based on recollection, by manipulating instructions at encoding (Experiment Two), and/or at retrieval (Experiment Three). The implications of the results of all three experiments are discussed in terms of recent accounts of memory retrieval and conscious awareness. (shrink)

Business is a representative institution of our times; it represents the spirit of our age. Modern business in general has displaced a remarkable ability to change. But the change yet to come will be something unprecedented. What is the nature of this change? What is the type of vision and sirategy that will help business as a social institution, and the organizations that are part of it, to navigate this evolutionary transition successfully? Or, in other words, what is the nature (...) of the paradigm shift needed to manage future change? These are the main questions business leaders and managers will be facing in the future. This article examines these questions in the light of Sri Aurobindo's vision. (shrink)
