"And Why Not?" Hegel, Comedy, and the End of Art

Towards the very end of his wide-ranging lectures on the philosophy of art, Hegel unexpectedly expresses a preference for comedy over tragedy. More surprisingly, given his systematic claims for his aesthetic theory, he suggests that this preference is arbitrary. This essay suggests that this arbitrariness is itself systematic, given Hegel’s broader claims about unity and necessity in art generally and his analysis of ancient as opposed to modern drama in particular. With the emergence of modern subjectivity, tragic plots lose their necessity and so their redemptive conclusions; comic plots disintegrate into mockery and entertainment. In many cases, the dramas in question consequently fail to be art. This does not, however, mean that art ends: insofar as it inspires humans to a better understanding of their unity with the divine, it will continue to meet its mandate. But the lack of necessity in modern drama means we are free to prefer happy endings. Hegel’s seemingly arbitrary preference is, in the end, systematically justified

Fight, Flight or Respect? First Encounters of the Other in Kant and Hegel

Immanuel Kant's description of humans' first encounter with each other depicts a peaceful recognition of mutual worth. G.W.F. Hegel's by contrast depicts a struggle to the death. I argue in this paper that Hegel's description of conflict results in an ethical theory that better preserves the distinctness of the other. I consider Christine Korsgaard's description of first encounters as a third alternative but conclude that Hegel's approach better accounts for the specific commitments we make--as family members, works, and citizens --in ethical life

Commitments of a Divided Self: Authenticity, Autonomy and Change in Korsgaard\u27s Ethics

C hristine Korsgaard attempts to reinterpret Kantian ethics in a way that might alleviate Bernard Williams’ famous worry that a man cannot save his drowning wife without determining impartially that he may do so. She does this by dividing a reflective self that chooses the commitments that make up an agent’s practical identity from a self defined as a jumble of desires. An agent, she then argues, must act on the commitments chosen by the reflective self on pain of disintegration. Using Harry Frankfurt’s emphasis on love as a final end, I argue that disintegration as motivation is not a more acceptable motivation than impartiality and so does not adequately address Williams’ criticism. I also argue that the idea of a divided self either leads to an infinite regress or to an implausible description of how our commitments evolve and change. To make this last claim, I discuss a case from John Updike’s novel In the Beauty of the Lilies

Life history and demographic determinants of effective/census size ratios as exemplified by brown trout (Salmo trutta)

A number of demographic factors, many of which related to human-driven encroachments, are predicted to decrease the effective population size (Ne) relative to the census population size (N), but these have been little investigated. Yet, it is necessary to know which factors most strongly impact Ne, and how to mitigate these effects through sound management actions. In this study, we use parentage analysis of a stream-living brown trout (Salmo trutta) population to quantify the effect of between-individual variance in reproductive success on the effective number of breeders (Nb) relative to the census number of breeders (Ni). Comprehensive estimates of the Nb/N ratio were reduced to 0.16–0.28, almost entirely due to larger than binomial variance in family size. We used computer simulations, based on empirical estimates of age-specific survival and fecundity rates, to assess the effect of repeat spawning (iteroparity) on Ne and found that the variance in lifetime reproductive success was substantially higher for repeat spawners. Random family-specific survival, on the other hand, acts to buffer these effects. We discuss the implications of these findings for the management of small populations, where maintaining high and stable levels of Ne is crucial to extenuate inbreeding and protect genetic variability.publishedVersio

Elimination of laboratory ozone leads to a dramatic improvement in the reproducibility of microarray gene expression measurements

BACKGROUND: Environmental ozone can rapidly degrade cyanine 5 (Cy5), a fluorescent dye commonly used in microarray gene expression studies. Cyanine 3 (Cy3) is much less affected by atmospheric ozone. Degradation of the Cy5 signal relative to the Cy3 signal in 2-color microarrays will adversely reduce the Cy5/Cy3 ratio resulting in unreliable microarray data. RESULTS: Ozone in central Arkansas typically ranges between ~22 ppb to ~46 ppb and can be as high as 60–100 ppb depending upon season, meteorological conditions, and time of day. These levels of ozone are common in many areas of the country during the summer. A carbon filter was installed in the laboratory air handling system to reduce ozone levels in the microarray laboratory. In addition, the airflow was balanced to prevent non-filtered air from entering the laboratory. These modifications reduced the ozone within the microarray laboratory to ~2–4 ppb. Data presented here document reductions in Cy5 signal on both in-house produced microarrays and commercial microarrays as a result of exposure to unfiltered air. Comparisons of identically hybridized microarrays exposed to either carbon-filtered or unfiltered air demonstrated the protective effect of carbon-filtration on microarray data as indicated by Cy5 and Cy3 intensities. LOWESS normalization of the data was not able to completely overcome the effect of ozone-induced reduction of Cy5 signal. Experiments were also conducted to examine the effects of high humidity on microarray quality. Modest, but significant, increases in Cy5 and Cy3 signal intensities were observed after 2 or 4 hours at 98–99% humidity compared to 42% humidity. CONCLUSION: Simple installation of carbon filters in the laboratory air handling system resulted in low and consistent ozone levels. This allowed the accurate determination of gene expression by microarray using Cy5 and Cy3 fluorescent dyes

Stakeholders' Participation in Planning and Priority Setting in the Context of a Decentralised Health Care system: the case of prevention of mother to child Transmission of HIV Programme in Tanzania.

In Tanzania, decentralisation processes and reforms in the health sector aimed at improving planning and accountability in the sector. As a result, districts were given authority to undertake local planning and set priorities as well as allocate resources fairly to promote the health of a population with varied needs. Nevertheless, priority setting in the health care service has remained a challenge. The study assessed the priority setting processes in the planning of the prevention of mother to child transmission of HIV (PMTCT) programme at the district level in Tanzania. This qualitative study was conducted in Mbarali district, south-western Tanzania. The study applied in-depth interviews and focus group discussions in the data collection. Informants included members of the Council Health Management Team, regional PMTCT managers and health facility providers. Two plans were reported where PMTCT activities could be accommodated; the Comprehensive Council Health Plan and the Regional PMTCT Plan that was donor funded. As donors had their own globally defined priorities, it proved difficult for district and regional managers to accommodate locally defined PMTCT priorities in these plans. As a result few of these were funded. Guidelines and main priority areas of the Ministry of Health and Social Welfare (MoHSW) also impacted on the ability of the districts and regions to act, undermining the effectiveness of the decentralisation policy in the health sector. The challenges in the priority setting processes revealed within the PMTCT initiative indicate substantial weaknesses in implementing the Tanzania decentralisation policy. There is an urgent need to revive the strategies and aims of the decentralisation policy at all levels of the health care system with a view to improving health service delivery

The evolving story of catadromy in the European eel (Anguilla anguilla)

Anguillid eels were once considered to be the classic example of catadromy. However, alternative life cycles have been reported, including skipping the freshwater phase and habitat shifting between fresh, brackish, and saltwater throughout the growth phase. There is a lack of knowledge regarding these alternate life strategies, for example, the proportion of individuals in the population that adopt them compared to classic catadromy. We provide a description of these alternate life cycle strategies in temperate anguillids, their possible drivers, and the methods available to investigate them. These methods (lethal and non-lethal), include otolith microchemistry, fatty acid and stable isotope analyses, parasite identification, blood transcriptomics, and electronic tags. We argue that since the current management framework for the European eel and other temperate eels is based mainly on the freshwater component of the population, it ignores eels growing in saline waters. Many of the factors that are thought to be responsible for the precipitous decline of the eel population are more prevalent in freshwater systems. Therefore, the contribution of saline eels may be more important than currently estimated. The habitat-shifting ability of eels may be all the more crucial for the persistence and recovery of those species that are endangered
