All rights reserved.Black Sigatoka or black leaf streak disease, caused by the Dothideomycete fungus Pseudocercospora fijiensis, is the most significant foliar disease of banana worldwide. Due to the lack of effective host resistance, management of this disease requires frequent fungicide applications, which greatly increase the economic and environmental costs to produce banana. Weekly applications in most banana plantations lead to rapid evolution of fungicide-resistant strains within populations causing disease-control failures throughout the world. Given its (...) extremely high economic importance, two strains of P. fijiensis were sequenced and assembled with the aid of a new genetic linkage map. The 74-Mb genome of P. fijiensis is massively expanded by LTR retrotransposons, making it the largest genome within the Dothideomycetes. Melting-curve assays suggest that the genomes of two closely related members of the Sigatoka disease complex, P. eumusae and P. musae, also are expanded. Electrophoretic karyotyping and analyses of molecular markers in P. fijiensis field populations showed chromosome-length polymorphisms and high genetic diversity. Genetic differentiation was also detected using neutral markers, suggesting strong selection with limited gene flow at the studied geographic scale. Frequencies of fungicide resistance in fungicide-treated plantations were much higher than those in untreated wild-type P. fijiensis populations. A homologue of the Cladosporium fulvum Avr4 effector, PfAvr4, was identified in the P. fijiensis genome. Infiltration of the purified PfAVR4 protein into leaves of the resistant banana variety Calcutta 4 resulted in a hypersensitive-like response. This result suggests that Calcutta 4 could carry an unknown resistance gene recognizing PfAVR4. Besides adding to our understanding of the overall Dothideomycete genome structures, the P. fijiensis genome will aid in developing fungicide treatment schedules to combat this pathogen and in improving the efficiency of banana breeding programs.

Studies of change blindness indicate that more intentional monitoring of changes is necessary to successfully detect changes as scene complexity increases. However, there have been conflicting reports as to whether people are aware of this relation between intention and successful change detection as scene complexity increases. Here we continue our dialogue with [Beck, M. R., Levin, D. T., & Angelone, B.. Change blindness blindness: Beliefs about the roles of intention and scene complexity in change detection. Consciousness and Cognition, 16, 31–51; (...) Beck, M. R., Levin, D. T., & Angelone, B.. Metacognitive errors in change detection: Lab and life converge. Consciousness and Cognition, 16, 58–62] by reporting two experiments that show participants do in fact intuit that more intentional monitoring is needed to detect changes as scene complexity increases. We also discuss how this dialogue illustrates the need for psychological studies to be grounded in measurements taken from real world situations rather than laboratory experiments or questionnaires.

In their target article, Wahring et al. present compelling evidence that romantic relationships may matter more to men than women, but their explanations remain largely proximate. We offer alternative evolutionary interpretations of the observed sex differences in falling in love, breakup initiation, remarriage, and mortality outside of relationships. We argue that these patterns better reflect sex-differentiated mating strategies, social alliance formation, vulnerabilities to singlehood, and the greater importance of female survival for offspring survival and hence for their reproductive success.

On what grounds will the rational man become a Christian? It is often assumed by many, especially non-Christians, that he will become a Christian if and only if he judges that the evidence available to him shows that it is more likely than not that the Christian theological system is true, that, in mathematical terms, on the evidence available to him, the probability of its truth is greater than half. It is the purpose of this paper to investigate whether or (...) not this is a necessary and sufficient condition for the rational man to adopt Christianity. (shrink)

People tend to perceive ongoing continuous activity as series of discrete events. This partitioning of continuous activity may occur, in part, because events correspond to dynamic patterns that have recurred across different contexts. Recurring patterns may lead to reliable sequential dependencies in observers' experiences, which then can be used to guide perception. The current set of simulations investigated whether this statistical structure within events can be used 1) to develop stable internal representations that facilitate perception and 2) to learn when (...) to update such representations in a self-organizing manner. These simulations demonstrate that experience with recurring patterns enables a system to accurately predict upcoming stimuli within an event, to identify boundaries between such events based on transient increases in prediction error, and to use such boundaries to improve prediction about subsequent activities.

Stakeholder theory is widely recognized as a management theory, yet very little research has considered its implications for individual managerial decision-making. In the two studies reported here, we used stakeholder theory to examine managerial decisions about balancing stakeholder interests. Results of Study 1 suggest that indivisible resources and unequal levels of stakeholder saliency constrain managers’ efforts to balance stakeholder interests. Resource divisibility also influenced whether managers used a within-decision or an across-decision approach to balance stakeholder interests. In Study 2 we (...) examined instrumental and normative implications of these two approaches. We conclude by considering the contributions of this research. (shrink)

An alleged moral right to informational privacy assumes that we should have control over information about ourselves. What is the philosophical justification for this control? I think that one prevalent answer to this question—an answer that has to do with the justification of negative rights generally—will not do.

Mr Olding's recent attack on my exposition of the argument from design gives me an opportunity to defend the central theses of my original article. My article pointed out that there were arguments from design of two types—those which take as their premisses regularities of copresence and those which take as their premisses regularities of succession. I sought to defend an argument of the second type. One merit of such an argument is that there is no doubt about the truth (...) of its premisses. Almost all objects in the world behave in a highly regular way describable by scientific laws. Further, any scientific explanation of such a regularity must invoke some more general regularity. The most general regularities of all are, as such, scientifically inexplicable. The question arises whether there is a possible explanation of another kind which can be provided for them, and whether their occurrence gives any or much support to that explanation. I urged that we do explain some phenomena by explanation of an entirely different kind from the scientific. We explain states of affairs by the action of agents who bring them about intentionally of their own choice. Regularities of succession, as well as other phenomena may be explained in this way. Explanation of this kind I will term intentional explanation. Intentional explanation of some phenomenon E consists in adducing an agent A who brought E about of his own choice and a further end G which, he believed, would be forwarded by the production of E.

Forty-two students enrolled in an environmental ethics course at a medium-sized metropolitan university in the southeastern United States were asked to complete a survey identifying their environmental ethic, prior to and after the course. Students were likewise asked if they saw benefits to taking an environmental ethics course and to explain those benefits. Before the course, most students could not identify an environmental ethic. Afterwards, most had adopted an ecocentric mindset. It was determined through a simple chi-square test that the (...) course had an impact in terms of how the students identify. None of the students viewed the course as a waste of time, with most feeling strongly that the course was life-enriching. All students surveyed saw benefit, with over half of the students suggesting the major benefit was that they were now better able to understand themselves and others. The survey findings were confirmed through structured interviews. (shrink)

Of all the themes treated by the mimes, perhaps the one that gave the most delight to their audiences throughout the centuries was that of adultery. References to it, from various parts of the ancient world, are found from the first century before Christ to the sixth century of the Christian era, and in many cases it is spoken of as a theme typical of the mime as a whole. There does not seem to be satisfactory evidence of its existence (...) in a genuinely dramatic form at an earner date. It is reported that the μαγδoί, among other impersonations, mimicked the behaviour of μoιχoί, but their performance, so far as can be discovered, was purely a piece of imitative buffoonery. When the theme of adultery was treated by Greek mimes of a later date, the approach seems to have been rather a psychological study of the adulteress than an attempt to bring out the dramatic possibilities inherent in the situation. This is certainly the case with Herondas' fifth mime, which portrays a lady jealously in love with a slave. Evidence from sources bearing a close relationship to the mime is equally negative. Thus a well-known Egyptian papyrus contains a song, written perhaps in the third or second century B.C., in which Helen complains of Menelaus' indifference to her after bringing her back from Troy; but this is far from constituting a variant on the adultery theme. The wall-song in Marissa, which was composed in the middle of the second century B.C., does indicate a situation in which a woman is trying to keep her lover's presence outside the house from the knowledge of another man with whom she is consorting inside.

Factors such as subsistence turnover, warfare, or interaction between different groups can be major sources of cultural change in human populations. Global demographic shifts such as the transition to agriculture during the Neolithic and more recently the urbanization and globalization of the twentieth century have been major catalysts for cultural change. Here, we test whether cultural traits such as patri/matrilocality and postmarital migration persist in the face of social upheaval and gene flow during the past 150 years in postcolonial South (...) Africa. The recent history of South Africa has seen major demographic shifts that resulted in the displacement and forced sedentism of indigenous Khoekhoe and San populations. During the expansion of the colonial frontier, the Khoe-San admixed with European colonists and enslaved individuals from West/Central Africa, Indonesia, and South Asia, introducing novel cultural norms. We conducted demographic interviews among Nama and Cederberg communities representing nearly 3,000 individuals across three generations. Despite the history of colonial expansion, and the subsequent incorporation of Khoe-San and Khoe-San-descendant communities into a colonial society with strong patrilocal norms, patrilocality is the least common postmarital residence pattern in our study populations today. Our results suggest that more recent forces of integration into the market economy are likely the primary drivers of change in the cultural traits examined in our study. Birthplace had a strong effect on an individual’s odds of migration, distance moved, and postmarital residence form. These effects are at least partially explained by the population size of the birthplace. Our results suggest that market factors local to birthplaces are important drivers of residence decisions, although the frequency of matrilocal residence and a geographic and temporal cline in migration and residence patterns also indicate the persistence of some historic Khoe-San cultural traits in contemporary groups.

This book reconsiders the meaning of modernism across the globe, stretching beyond both the Western modernist canon and the literary-heavy scope of the field to a broader cultural consideration of global modernisms and modernity. Through the use of masks as a thematic focus, the volume challenges popular assumptions about what modernism looks like, what modernity is, and how each of these ideas are produced within a historical moment.
