Lost voices in the poetry of Catullus: a study in persona and politics

This thesis aims at recovering aspects of the poetry of Catullus often denied or ignored by critics: the roles of the poet himself, and of politics in his poetry. These I call the 'lost voices'. The first voice is that of the poet as opposed to a fictional persona called 'Catullus'. Taking the poet's I to refer back to himself re-establishes the poet's role in understanding the meaning of the poems, and also raises the related question of how we should interpret the numerous biographical references Catullus makes. In exploring the history of the intrusion of poets into their verses I demonstrate the likelihood that Catullus wrote for an audience who would take his poetry as referring to his own life, unless he directed them otherwise. I then argue for Catullus' strong political involvement as being a key feature of a considerable number of his poems. I explore first the particularly personal nature of Roman politics and how for many elite Roman men politics was a way of life not a career choice. In examining what we can discover of Catullus' own status and position in society, I show how he should be considered very much part of the Roman elite. As such, politics is a factor that cannot be dismissed in his relationship with Lesbia (Clodia), particularly in his use of the concept of amicitia, and I re-examine the traditional identification of Lesbia with Clodia Metelli, arguing that such a partnership adds another dimension to Catullus' poems as well as his political involvement. I conclude with examining the numerous poems that reflect Catullus' explicit political activity, focusing on his relationship with the key political protagonists of his day, Caesar and Pompey, as well as other major figures, such as Clodius, Cicero, Vatinius, Piso, and Memmius

The importance of user perspective in the evolution of MaaS

The rapid emergence of Mobility as a Service (MaaS) into the transport sector’s lexicon has brought with it an air of expectation that suggests a future mobility revolution. This paper focusses on the user perspective and offers a deepening of socio-technical thinking about MaaS and its prospects. It first provides an examination of what is understood to date about MaaS in what is a new but rapidly evolving body of literature. This highlights the concept of MaaS as a ‘mobility system beyond the private car’ and the new centrality of a ‘mobility intermediary’ layer in that system. The paper then focuses and elaborates upon its contention that MaaS is neither new nor revolutionary but is rather an evolutionary continuation in terms of transport integration. Emerging from an era of unimodal travel information systems becoming multimodal and then integrated multimodal information services, MaaS is now about adding seamless booking, payment and ticketing to the integration offer. The paper puts forward a ‘Levels of MaaS Integration (LMI) taxonomy’ analogous to the level 0-5 SAE taxonomy for automation of road vehicles. This taxonomy, designed around the user perspective (including cognitive user effort), concerns operational, information and transactional integration that it is suggested reflect a hierarchy of user need. From a synthesis of insights from the ‘pre-MaaS’ literature concerning choice making for travel and the role of information, a MaaS behavioural schema is provided to illustrate potential consideration and adoption of MaaS from the user perspective. In concluding, the paper considers what a user perspective reveals for the future prospects of MaaS and in particular for the mobility intermediaries

Consistent use of a combination product versus a single product in a safety trial of the diaphragm and microbicide in Harare, Zimbabwe.

BACKGROUND: We examined the use and acceptability of a combination product (diaphragm and gel) compared to a single product (gel) during a 6-month safety trial in Zimbabwe. STUDY DESIGN: Women were randomized to the use of a diaphragm with gel or the use of gel alone, in addition to male condoms. Ever use and use of study product on the last act of sexual intercourse were assessed monthly by Audio Computer-Assisted Self-Interviewing. Acceptability, correct use and consistent use (use at every sexual act during the previous 3 months) were measured on the last visit by face-to-face interview. Predictors of consistent use were examined using multivariate logistic regression analyses. RESULTS: In this sample of 117 sexually active, monogamous, contracepting women, rates of consistent use were similar in both groups (59.7% for combination method vs. 56.4% for gel alone). Product acceptability was high, but was not independently associated with consistent use. Independent predictors of consistent use included age [adjusted odds ratio (AOR)=1.08; 95% confidence interval (95% CI)=1.01-1.16], consistent condom use (AOR=3.85; 95% CI=1.54-9.63) and having a partner who approves of product use (AOR=2.66; 95% CI=1.10-6.39). CONCLUSIONS: Despite high reported acceptability and few problems with the products, the participants reported only moderate product adherence levels. Consistent use of condoms and consistent use of products were strongly associated. If observed in other studies, this may bias the estimation of product effectiveness in future trials of female-controlled methods

An appreciation of the prescience of Don Gilbert (1930‐2011): master of the theory and experimental unraveling of biochemical and cellular oscillatory dynamics

We review Don Gilbert's pioneering seminal contributions that both detailed the mathematical principles and the experimental demonstration of several of the key dynamic characteristics of life. Long before it became evident to the wider biochemical community, Gilbert proposed that cellular growth and replication necessitate autodynamic occurrence of cycles of oscillations that initiate, coordinate, and terminate the processes of growth, during which all components are duplicated and become spatially re‐organized in the progeny. Initiation and suppression of replication exhibit switch‐like characteristics: i.e., bifurcations in the values of parameters that separate static and autodynamic behavior. His limit cycle solutions present models developed in a series of papers reported between 1974 and 1984, and these showed that most or even all of the major facets of the cell division cycle could be accommodated. That the cell division cycle may be timed by a multiple of shorter period (ultradian) rhythms, gave further credence to the central importance of oscillatory phenomena and homeodynamics as evident on multiple time scales (seconds to hours). Further application of the concepts inherent in limit cycle operation as hypothesized by Gilbert more than 50 years ago are now validated as being applicable to oscillatory transcript, metabolite and enzyme levels, cellular differentiation, senescence, cancerous states, and cell death. Now, we reiterate especially for students and young colleagues, that these early achievements were even more exceptional, as his own lifetime's work on modeling was continued with experimental work in parallel with his predictions of the major current enterprises of biological research

Identifying features associated with higher-quality hospital care and shorter length of admission for people with dementia : a mixed-methods study

Background: Concerns have repeatedly been expressed about the quality of inpatient care that people with dementia receive. Policies and practices have been introduced that aim to improve this, but their impact is unclear. Aims: To identify which aspects of the organisation and delivery of acute inpatient services for people with dementia are associated with higher-quality care and shorter length of stay. Design: Mixed-methods study combining a secondary analysis of data from the third National Audit of Dementia (2016/17) and a nested qualitative exploration of the context, mechanism and outcomes of acute care for people with dementia. Setting: Quantitative data from 200 general hospitals in England and Wales and qualitative data from six general hospitals in England that were purposively selected based on their performance in the audit. Participants: Quantitative data from clinical records of 10,106 people with dementia who had an admission to hospital lasting ≥ 72 hours and 4688 carers who took part in a cross-sectional survey of carer experience. Qualitative data from interviews with 56 hospital staff and seven carers of people with dementia. Main outcome measures: Length of stay, quality of assessment and carer-rated experience. Results: People with dementia spent less time in hospital when discharge planning was initiated within 24 hours of admission. This is a challenging task when patients have complex needs, and requires named staff to take responsibility for co-ordinating the discharge and effective systems for escalating concerns when obstacles arise. When trust boards review delayed discharges, they can identify recurring problems and work with local stakeholders to try to resolve them. Carers of people with dementia play an important role in helping to ensure that hospital staff are aware of patient needs. When carers are present on the ward, they can reassure patients and help make sure that they eat and drink well, and adhere to treatment and care plans. Clear communication between staff and family carers can help ensure that they have realistic expectations about what the hospital staff can and cannot provide. Dementia-specific training can promote the delivery of person-centred care when it is made available to a wide range of staff and accompanied by ‘hands-on’ support from senior staff. Limitations: The quantitative component of this research relied on audit data of variable quality. We relied on carers of people with dementia to explore aspects of service quality, rather than directly interviewing people with dementia. Conclusions: If effective support is provided by senior managers, appropriately trained staff can work with carers of people with dementia to help ensure that patients receive timely and person-centred treatment, and that the amount of time they spend in hospital is minimised. Future work: Future research could examine new ways to work with carers to co-produce aspects of inpatient care, and to explore the relationship between ethnicity and quality of care in patients with dementia.

Heart rate variability during high-speed treadmill exercise and recovery in Thoroughbred racehorses presented for poor performance

Background: Heart rate variability (HRV) analysis measures the inter-beat interval variation of successive cardiac cycles. Measurement of these indices has been used to assess cardiac autonomic modulation and for arrhythmia identification in exercising horses.Objectives: To report HRV indices during submaximal exercise, strenuous exercise and recovery, and explore relationships with clinical conditions (arrhythmias, lameness, equine gastric ulcer syndrome (EGUS), lower airway inflammation and upper respiratory tract obstructions (URTO) in Thoroughbred (TB) racehorses.Study Design: Retrospective, observational cross-sectional study.Methods: One hundred and eighty Thoroughbred horses underwent a treadmill exercise test with simultaneous electrocardiographic (ECG) recording. Time-domain HRV indices (standard deviation of the R-R interval (SDRR); root mean square of successive differences (RMSSD)) were derived for submaximal and strenuous exercise and recovery segments. Clinical conditions (arrhythmia (during each phase of exercise), lameness, EGUS, lower airway inflammation and URTO) were assigned to binary categories for statistical analysis. Relationships between selected HRV indices and the clinical conditions were explored using linear regression models. Results: During submaximal exercise, lameness was associated with decreased logRMSSD (B= -0.19 95% CI -0.31 to -0.06, P= 0.006) and arrhythmia was associated with increased logRMSSD (B= 0.31 95% CI 0.01-.608, P=0.04). During strenuous exercise, arrhythmia was associated with increased HRV indices (logSDRR B= 0.51 95% CI 0.40-0.62, PMain Limitations: The main limitations of this retrospective study were that not every horse had the full range of clinical testing, therefore some horses may have had undetected abnormalities. Conclusions: The presence of arrhythmia increased HRV in both phases of exercise and recovery. Lameness decreased HRV during submaximal exercise

Improved estimates of digestion correction factors and passage rates for harbor seal (Phoca vitulina) prey in the northeast Atlantic

Diet composition in pinnipeds is widely estimated using hard prey remains recovered from feces. To estimate the size and number of prey represented in fecal samples accurately, digestion correction factors (DCFs) must be applied to measurements and counts of fish otoliths and cephalopod beaks. In this study, 101 whole prey feeding trials were conducted with six harbor seals (Phoca vitulina) and 18 prey species. We derived species- and grade-specific estimates of digestion coefficients (DCs) and species-specific recovery rates (RRs) to account for partial and complete digestion, respectively. Greater than 98% of otoliths were passed within three days of consumption. RRs were smallest for Atlantic salmon smolts (RR = 0.306, SE = 0.031) and increasingly larger for sandeels (RR = 0.494, SE = 0.017), flatfish (RR = 0.789, SE = 0.033), and large gadoids (RR = 0.944, SE = 0.034). Species-specific otolith width DCs were smallest for Trisopterus species (DC = 1.14, SE = 0.015) and increasingly larger for flatfish (DC = 1.27, SE = 0.045), large gadoids (DC = 1.32, SE = 0.067) and sandeels (DC = 1.57, SE = 0.035). RRs were similar to those from gray seals (Halichoerus grypus), but harbor seal species- and grade-specific DCs were generally smaller. Differences in partial and complete digestion rates among prey species and between seal species highlight the importance of applying DCFs when reconstructing diet.PostprintPeer reviewe
