The Art of the Stage Machinist: A Dramatic Reconstruction of Aeschylus’ Linear Tragedy, Prometheus Bound

Tragedy purposefully engages an audience and does not merely entertain. Its six inherent components include: character, diction, thought, spectacle and song. Aristotle’s position is that the text in and of itself should be strong, complete and able to stand on its own. According to Aristotle, the inferior additions of stagecraft and spectacle do not greatly add to the dramatic potential already evident in the poetry. A fully-realized, Attic, tragic production will provide valuable insight into the intricacies of stagecraft and spectacle. This insight allows readers to appreciate the meticulous details of constructing a piece of performance art that doesn’t deal solely with words on the page. The driving purpose behind this thesis is not an egocentric odyssey which will allow me to direct, design and reconstruct a complete tragedy by myself. Rather, the deconstruction of an Attic tragedy allows us to more fully engage with a drama not solely through its textual intricacies but also through its physical aspects. After all, the words on the page do not adequately encapsulate a complete tragic production and the cathartic elements that accompany live theatre

Soviet Comrades\u27 Courts

A major aspect of Soviet criminal law reform since 1959 has been the transfer of certain judicial functions to Comrades\u27 Courts, which are nonprofessional tribunals established to try petty offenses in enterprises, apartment houses, collective farms, universities, and elsewhere. These are called social, rather than state, agencies, because they are not staffed by civil servants but by volunteers and because they are conceived to perform a persuasive rather than a coercive function. Apart from their practical importance, they play an important part in symbolizing the theory that in the new period of expanded construction of communism there will be a decline in the use of formal and coercive sanctions and an increase in the use of informal and popular instruments of self-government. Under communism itself, the first stage of which, according to the 1961 Party Program, is to be achieved by 1980, this process of the dying out of the state, it is said, will be accelerated, as crime gradually disappears and such remnants of the past as the spirit of individualism and money-grubbing, the psychology of private property, and moral callousness cease to exist

Ionization dynamics of iron plumes generated by laser ablation versus a laser‐ablation‐assisted‐plasma discharge ion source

The ionization dynamics (iron ion and neutral atom absolute line densities) produced in the KrF excimer laser ablation of iron and a laser‐ablation‐assisted plasma discharge (LAAPD) ion source have been characterized by a new dye‐laser‐based resonant ultraviolet interferometry diagnostic. The ablated material is produced by focusing a KrF excimer laser (248 nm,<1 J, 40 ns) onto a solid iron target. The LAAPD ion source configuration employs an annular electrode in front of the grounded target. Simultaneous to the excimer laser striking the target, a three‐element, inductor–capacitor, pulse‐forming network is discharged across the electrode–target gap. Peak discharge parameters of 3600 V and 680 A yield a peak discharge power of 1.3 MW through the laser ablation plume. Iron neutral atom line densities are measured by tuning the dye laser near the 271.903 nm (a 5D–y 5P0) ground‐state and 273.358 nm (a 5F–w 5D0) excited‐state transitions while iron singly ionized line densities are measured using the 263.105 nm (a 6D–z 6D0) and 273.955 nm (a 4D–z 4D0) excited‐state transitions. The line density, expansion velocity, temperature, and number of each species have been characterized as a function of time for laser ablation and the LAAPD. Data analysis assuming a Boltzmann distribution yields the ionization ratio (ni/nn) and indicates that the laser ablation plume is substantially ionized. With application of the discharge, neutral iron atoms are depleted from the plume, while iron ions are created, resulting in a factor of ∼5 increase in the plume ionization ratio. Species temperatures range from 0.5 to 1.0 eV while ion line densities in excess of 1×1015 cm−2 have been measured, implying peak ion densities of ∼1×1015 cm−3. © 1996 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70077/2/JAPIAU-79-5-2287-1.pd

Effects of laser‐ablation target damage on particulate production investigated by laser scattering with deposited thin film and target analysis

Experiments have been carried out to correlate ablated particulate density and size to the number of KrF excimer laser (248 nm, 40 ns, <1.2 J) pulses incident on a single location of a pure solid aluminum target and to relate particulate production to target surface damage. An analysis of laser ablation deposited aluminum films on silicon substrates was used to determine the density of ablated particulate greater than 0.5 μm in diameter. For an undamaged target, the laser deposited particulate density was on the order of 8.6×105 cm−2 per 1000 shots. A damaged target (following 1000 laser pulses) produced a density on the order of 1.6×106 cm−2 per 1000 shots on the substrate. Dye laser optical scattering was also used to measure, in real time, the velocity of the particulate and the relative particulate density in the laser‐ablation plume versus target damage. Results indicated a rapid rise in the production of particulate as target damage was increased up to 3000 laser pulses; after this number of shots the density of particulate in the laser ablation plume saturated. A peak in the scattered light for each stage of target damage occurred 40 μs after the initial KrF laser pulse, translating to a velocity of about 100 m/s for the smaller particulate (<1 μm diameter). The later scattered signal, around 160 μs, was apparently due to the larger particulate (5–15 μm), traveling at a velocity of approximately 25 m/s. Particulate production is related to the formation of laser ablation‐induced cones on the damaged targets. © 1996 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70140/2/APPLAB-68-23-3245-1.pd

“Child marriage” declines as social change? The influence of global priorities, social determinants and norms in changing adolescent marriages in southcentral Uganda, 1999-2018

Over the last 20 years, adolescent health researchers, practitioners and advocates have zeroed-in on the global problem of ‘child marriage.’ Defined as a formal or informal marital union before 18 years, child marriage affects both boys and girls, but disproportionally affects girls. Globally, child marriage is noticeably prevalent but on a downward trend, with the proportion of 20-24 year old women marrying before 18 years decreasing from 25% to 19%, from 2008 to 2020 (UNICEF, 2018; 2022). Extensive research has shown the adverse consequences of marrying during adolescence, ranging from increased risk of maternal mortality and birth complications, intimate partner violence (IPV), adverse mental health and intergenerational poverty outcomes (Burgess et al., 2022; Clark, 2004; Nour, 2009; Otoo-Oyortey & Pobi, 2003; UNICEF, 2018). From a rights perspective, child marriage is considered a violation of girls’ and boys’ ‘right’ to fully consent into marriage before reaching age of majority, internationally recognized as 18 years of age (Bruce, 2003; Nour, 2009). As such, child marriage is recognized as a human rights violation under several international treaties, including the Convention on the Rights of the Child (CRC). The term ‘child marriage’ is commonly used to convey the human rights violations that early marital practices have for under-age girls and boys. While the term ‘child marriage’ has mobilized consensus and solidarity toward the issue, this terminology also homogenizes the issue of marriage as a problem affecting the ‘girl child’ with little to no agency in the marriage decision-making process. More specific to Uganda, this ‘child marriage’ terminology can be problematic where marriage more commonly occurs during middle to late adolescence (15-19 years) and when adolescents may exert varying degrees of agency and consent in the marital decision-making process. Except for Chapter 1 which explores ‘child marriage’ global and national movements, I intentionally use the terminology ‘adolescent marriage’ (as marriage before age 18), rather than ‘child marriage,’ throughout this dissertation. Despite the global push to ‘end child marriage’ over the last decade, there is limited research about how broader social and structural factors may be driving declines in adolescent marriage (Muthengi et al., 2021; Plesons et al., 2021). In particular, we have a limited understanding about how global efforts, social processes and norms might work together to drive marriage declines among adolescents. Through a mix of policy, quantitative and qualitative methods, this dissertation examines the policy, structural and social mechanisms that have contributed to declining adolescent marriage among adolescent girls in the context of southcentral Uganda. Chapter 1 begins with a broader contextual lens, examining the political evolution of the global ‘child marriage’ movement, and how the ‘problem’ of child marriage was then taken-up by government and civil society actors in Uganda. This chapter is informed by 20 key informant interviews with Ugandan and global stakeholders working on child marriage and a desk review of over 130 documents gathered across four years. This chapter highlights how the global ‘child marriage’ movement marked a political shift in adolescent girl funding, repackaging the issue of early marriage as an issue of ‘child protection.' The focus on child protection, rather than adolescent sexuality, was instrumental in mobilizing attention from liberal and conservative funders in the Global North and policy-makers in the Global South. In the priority country of Uganda, multiple factors influenced the national policy uptake of child marriage, including: 1. Regional campaigns that created consensus among Eastern and Southern African country leadership to address child marriage; 2. The availability of national data that showed the reach and severity of child marriage within Uganda; 3. The cultural and political appeal of child marriage as an issue of ‘child rights’, rather than one of ‘sexuality,’ and; 4. A network of government leaders, academics, international non-governmental organizations (INGOs) and civil society organizations (CSOs) who coalesced behind the issue in Uganda. Chapter 2 focuses-in on the southcentral region of Uganda, leveraging close to 20 years of quantitative data to understand how social and structural factors are affecting adolescent marriage declines in the region. Using data from 13 surveys (1999-2018) of the Rakai Community Cohort Study (RCCS), I couple decomposition and causal inference methods to assess how social determinants and adolescent pregnancies have contributed to adolescent marriage declines among 15 to 17 year old girls. I find that both marriages and pregnancies among adolescent girls substantially declined over the last 20 years, from 24% to 6%, and 28% to 8%, respectively, between 1999 and 2018, as a result of educational and economic improvements. Among all social determinants, girls’ secondary schooling was more closely associated with lower risk of marriage and pregnancy (aOR marriage = 0.09; 95%CI=0.07, 0.12; aOR pregnancy = 0.14; 95% CI=0.11; 0.19). In the causal mediation analyses, lower pregnancy rates partially explained the positive effect of higher secondary schooling on lower risk of adolescent marriage. Decomposition analyses showed that the declines in adolescent marriage between 1999 to 2018 were primarily attributed to pregnancy declines, and to a lesser extent, improvements in education and SES. These findings reemphasize the sizeable role of education in preventing adolescent marriages, in line with Uganda’s national educational investments such as universal primary education (UPE). Yet, these findings also underline the importance of adolescent pregnancy prevention to delay age at marriage. In the same region of southcentral Uganda, Chapter 3 uses secondary ethnographic data to more deeply explore the social mechanisms and norms that have contributed to changes in adolescent marriages. I qualitatively explore how the region’s social and economic changes have affected social norms about adolescent sex, courtship, and marriage in Rakai, Uganda. This analysis is informed by 16 focus group discussions and 15 key informant interviews conducted in 2018 with younger and older women and men, ranging from 16 to 77 years old. In comparing generational perspectives, I identify a ‘normative transition’, in which new structures are transforming courtship and marriage processes for young people. First, the HIV epidemic significantly weakened family structures, and in the process, courtship and marriage guidance previously provided by families and elders; second, the loss of land ownership in between generations has made marriage preparations more difficult for young people; and third, new social spaces outside the family home – including discos, mobile phones and schools - have expanded young people’s romantic geographies prior to marriage. These changes have reduced the importance of the family institution in the marital decision-making process, while increasing young women’s and men’s autonomy in engaging in premarital sex, choosing their partners, and delaying marriage. Although these changes have delayed age at marriage beyond adolescence, this transition has introduced unanticipated challenges for young people as they enter adulthood, including lack of overall parental, familial and elder guidance in their relationship and marriage formation processes. Taken together, these findings highlight the complexity of adolescent marriage changes and prevention efforts at the global, Ugandan, and southcentral region of Uganda. First, global and national ‘child marriage’ movements played a significant role in the uptake of child marriage as an issue of ‘child protection’, rather than one about ‘sexuality’ in Uganda. Yet looking at the context of southcentral Uganda, adolescent pregnancies and adolescent marriages declines appear to be closely linked, highlighting the importance of conceptualizing adolescent marriage as not just a child protection issue, but one of adolescent sex and sexuality. Lastly, I find that broader structural and social changes in Rakai have substantially changed adolescent norms around sex, courtship, and marriage, delaying age at marriage in between generations. However, young people are encountering new challenges as they enter adulthood and romantic relationships in the absence of pre-existing elder and familial systems and networks. Additional research should focus on understanding the unintended consequences of catalyzing norm change and delaying age at marriage, including how these changes might affect familial and community relationships and kinships. Twenty years into the global push to end ‘child marriage’, this dissertation research provides new insights into the complex structural, social and sexuality drivers of adolescent marriage changes in Uganda. Despite the substantial progress in adolescent marriage declines, this research points to key gaps that will need to be addressed to improve adolescent SRH rights and needs in Uganda, the East African region, and beyond. Of particular importance is the need to center adolescent sexuality within current child marriage efforts, as well as focusing on the broader social changes affecting adolescent relationship formation, rather than exclusively focusing on age at marriage as a marker of social change

The most creative organization in the world? The BBC, 'creativity' and managerial style

The managerial styles of two BBC directors-general, John Birt and Greg Dyke, have often been contrasted but not so far analysed from the perspective of their different views of 'creative management'. This article first addresses the orthodox reading of 'Birtism'; second, it locates Dyke's 'creative' turn in the wider context of fashionable neo-management theory and UK government creative industries policy; third, it details Dyke's drive to change the BBC's culture; and finally, it concludes with some reflections on the uncertainties inherent in managing a creative organisation

Novel Protein Kinase Signaling Systems Regulating Lifespan Identified by Small Molecule Library Screening Using Drosophila

Protein kinase signaling cascades control most aspects of cellular function. The ATP binding domains of signaling protein kinases are the targets of most available inhibitors. These domains are highly conserved from mammals to flies. Herein we describe screening of a library of small molecule inhibitors of protein kinases for their ability to increase Drosophila lifespan. We developed an assay system which allowed screening using the small amounts of materials normally present in commercial chemical libraries. The studies identified 17 inhibitors, the majority of which targeted tyrosine kinases associated with the epidermal growth factor receptor (EGFR), platelet-derived growth factor (PDGF)/vascular endothelial growth factor (VEGF) receptors, G-protein coupled receptor (GPCR), Janus kinase (JAK)/signal transducer and activator of transcription (STAT), the insulin and insulin-like growth factor (IGFI) receptors. Comparison of the protein kinase signaling effects of the inhibitors in vitro defined a consensus intracellular signaling profile which included decreased signaling by p38MAPK (p38), c-Jun N-terminal kinase (JNK) and protein kinase C (PKC). If confirmed, many of these kinases will be novel additions to the signaling cascades known to regulate metazoan longevity
