Trash, a curatorial : an ethnographic and visual study of waste in urban Hong Kong

This is an ethnography of waste in the streets of urban Hong Kong and a curatorial inquiry into the significance of its visuality. Presented in the form of a triptych, the dissertation probes and portrays fragments of urban life in Hong Kong, consequently opening up a new vista for intellectual and social engagement at the juncture of aesthetics, lived experiences, and power. While urban density provides for its equivalent in trash, much of Hong Kong’s refuse first lands in the streets. It is thereupon regulated to be rendered invisible through government organisation which corresponds with what Gay Hawkins (2007) calls “the modern imaginary of the tidy city” where order and hygiene are brought together towards a ‘smooth running of things’ (Žižek 2006 in Moore 2012). Hawkins (2007) also states, however, that no city \u27can hide the excesses of consumption\u27. Indeed, no matter the attempts at the ridding of rubbish in the modern city, trash keeps reappearing. Also Hong Kong has a waste problem that goes beyond its exhausting landfills. ‘It’s everywhere!’, as its collectors indicate. Both formal and informal collectors continuously pick up trash. This conflicting location between desired tidiness, persistent trash, and constant collection, it is argued here, is a political sphere that is largely negotiated visually. Taking on the collectors’ views of “trash in place” (in the streets; the city), I therefore rethink what is commonly understood as “matter out of place” (Douglas 2002) in the modern city. Emphasising the significance of the visuality of trash – understanding visuality as “an embodied process of situation, positioning, re-memory, encounter, cognition and interpretation” (Rose and Tolia Kelly 2012) – I advance the ethnographic project with curatorial practices, putting the collectors’ perspectives on trash and those of local artists in dialogue. From this dialogue, this thesis presents three “panels” on waste in urban Hong Kong. The “panels” engage in matters of order and duty, social networks and places, and the visuality and instantaneous of the everyday, to then reconsider the aesthetics of trash and the politics of urban life more generally. The thesis presents a range of different stories, therefore, about the instant undoing of disorder in the modern city, the (re)valuing of discards via social networks of excess, and the “unordering of the sensible” by means of a repositioning of trash. The triptych in its entirety, finally, manifests possibilities for methodological innovations on everyday matters of aesthetics and power

Genetic and functional characterization of the gene cluster directing the biosynthesis of putisolvin I and II in Pseudomonas putida strain PCL1445

Pseudomonas putida PCL1445 secretes two cyclic lipopeptides, putisolvin I and putisolvin II, which possess a surface-tension-reducing ability, and are able to inhibit biofilm formation and to break down biofilms of Pseudomonas species including Pseudomonas aeruginosa. The putisolvin synthetase gene cluster (pso) and its surrounding region were isolated, sequenced and characterized. Three genes, termed psoA, psoB and psoC, were identified and shown to be involved in putisolvin biosynthesis. The gene products encode the 12 modules responsible for the binding of the 12 amino acids of the putisolvin peptide moiety. Sequence data indicate that the adenylation domain of the 11th module prioritizes the recognition of Val instead of Leu or Ile and consequently favours putisolvin I production over putisolvin II. Detailed analysis of the thiolation domains suggests that the first nine modules recognize the D form of the amino acid residues while the two following modules recognize the L form and the last module the L or D form, indifferently. The psoR gene, which is located upstream of psoA, shows high similarity to luxR-type regulatory genes and is required for the expression of the pso cluster. In addition, two genes, macA and macB, located downstream of psoC were identified and shown to be involved in putisolvin production or export

Blockchain For Food: Making Sense of Technology and the Impact on Biofortified Seeds

The global food system is under pressure and is in the early stages of a major transition towards more transparency, circularity, and personalisation. In the coming decades, there is an increasing need for more food production with fewer resources. Thus, increasing crop yields and nutritional value per crop is arguably an important factor in this global food transition. Biofortification can play an important role in feeding the world. Biofortified seeds create produce with increased nutritional values, mainly minerals and vitamins, while using the same or less resources as non-biofortified variants. However, a farmer cannot distinguish a biofortified seed from a regular seed. Due to the invisible nature of the enhanced seeds, counterfeit products are common, limiting wide-scale adoption of biofortified crops. Fraudulent seeds pose a major obstacle in the adoption of biofortified crops. A system that could guarantee the origin of the biofortified seeds is therefore required to ensure widespread adoption. This trust-ensuring immutable proof for the biofortified seeds, can be provided via blockchain technology

Educators' experiences with governance in curriculum change processes; a qualitative study using rich pictures

In the midst of continuous health professions curriculum reforms, critical questions arise about the extent to which conceptual ideas are actually put into practice. Curricula are often not implemented as intended. An under-explored aspect that might play a role is governance. In light of major curriculum changes, we explored educators’ perspectives of the role of governance in the process of translating curriculum goals and concepts into institutionalized curriculum change at micro-level (teacher–student). In three Dutch medical schools, 19 educators with a dual role (teacher and coordinator) were interviewed between March and May 2018, using the rich pictures method. We employed qualitative content analysis with inductive coding. Data collection occurred concurrently with data analysis. Different governance processes were mentioned, each with its own effects on the curriculum and organizational responses. In Institute 1, participants described an unclear governance structure, resulting in implementation chaos in which an abstract educational concept could not be fully realized. In Institute 2, participants described a top–down and strict governance structure contributing to relatively successful implementation of the educational concept. However it also led to demotivation of educators, who started rebelling to recover their perceived loss of freedom. In Institute 3, participants described a relatively fragmentized process granting a lot of freedom, which contributed to contentment and motivation but did not fully produce the intended changes. Our paper empirically illustrates the importance of governance in curriculum change. To advance curriculum change processes and improve their desired outcomes it seems important to define and explicate both hard and soft governance processes

At identical isowork rates, ageing influences cardiorespiratory adaptations in COPD out-patients

SummaryPurposeTo determine the extent to which younger COPD patients improve their cardiorespiratory function during exercise in comparison with older COPD patients, as a result of exercise training.MethodsThirty-nine COPD patients underwent an exercise program. They were divided into two groups: a younger group (57.2±1.0 years, n=18 patients) and an older group (68.8±0.6 years, n=21 patients). Forced expiratory volume in 1s was lower than 55% of the predicted value for all patients.ResultsAfter training, V˙O2 symptom-limited significantly improved by 10.3% and 8.4% for the younger and older COPD patients, respectively (P<0.05). Peak power significantly improved by 25.2% and 17.8% in the younger and older groups, respectively (P<0.05) with a greater improvement for the younger group (P<0.05). At submaximal exercise, ventilation and heart rate significantly decreased after training in the younger COPD patients (P<0.05) with no significant modification in the older COPD patients.ConclusionsThe results suggest that all patients with COPD benefit from exercise rehabilitation at maximal exercise workload, however, according to their age, submaximal cardiorespiratory adaptations were greater in younger patients

No effect of glutamine ingestion on indices of oxidative metabolism in stable COPD

COPD patients have reduced muscle glutamate which may contribute to an impaired response of oxidative metabolism to exercise. We hypothesised that prior glutamine supplementation would enhance View the MathML source peak, View the MathML source at lactate threshold and speed pulmonary oxygen uptake kinetics in COPD. 13 patients (9 males, age 66 ± 5 years, mean ± SD) with severe COPD (mean FEV1 0.88 ± 0.23 l, 33 ± 7% predicted) performed on separate days ramp cycle-ergometry (5–10 W min−1) to volitional exhaustion and subsequently square-wave transitions to 80% estimated lactate threshold (LT) following consumption of either placebo (CON) or 0.125 g kg bm−1 of glutamine (GLN) in 5 ml kg bm−1 placebo. Oral glutamine had no effect on peak or View the MathML source at LT, {View the MathML source peak: CON = 0.70 ± 0.1 l min−1 vs. GLN = 0.73 ± 0.2 l min−1; LT: CON = 0.57 ± 0.1 l min−1 vs. GLN = 0.54 ± 0.1 l min−1} or View the MathML source kinetics {tau: CON = 68 ± 22 s vs. GLN = 68 ± 16 s}. Ingestion of glutamine before exercise did not improve indices of oxidative metabolism in this patient group

Interval exercise versus continuous exercise in patients with moderate to severe chronic obstructive pulmonary disease – study protocol for a randomised controlled trial [ISRCTN11611768]

BACKGROUND: Physical exercise has become a cornerstone of management of chronic obstructive pulmonary disease (COPD) because it leads to clinically relevant improvements of exercise capacity and health-related quality of life (HRQL). Despite the scarcity of randomised trials directly comparing exercise protocols, current guidelines recommend high intensity continuous exercise for lower extremities as the probably most effective exercise modality. However, for patients admitted to inpatient respiratory rehabilitation programmes, it is often difficult to initiate such an exercise programme because they are severely limited by dyspnoea and leg fatigue and therefore unable to perform continuous exercise at higher intensities and for periods longer than 30 minutes. Interval exercise may be an attractive alternative for these COPD patients because it allows high intensity exercise with recovery periods. The aim of this study is to assess if interval exercise compared to high intensity continuous exercise is not of inferior effectiveness in terms of HRQL and exercise capacity improvements but associated with better exercise tolerance in patients with moderate to severe COPD at the beginning of a respiratory rehabilitation. METHODS/DESIGN: We will assign patients with moderately severe to severe COPD to either continuous exercise or interval exercise using a stratified randomisation. Patients will follow 12–15 exercise sessions during a comprehensive inpatient respiratory rehabilitation. Primary end point for effectiveness is HRQL as measured by the Chronic Respiratory Questionnaire (CRQ) two weeks after the end of rehabilitation and secondary endpoints include additional clinical outcomes such as functional exercise capacity, other HRQL measures, patients' experience of physical exercise as well as physiological measures of the effects of physical exercise such as cardiopulmonary exercise testing. Including expected drop-outs, we will need 52 patients per group to show differences corresponding to the minimal clinically important difference of the CRQ. Outcome assessors and investigators involved in data analysis will be blinded to group assignment until analyses have been carried out. DISCUSSION: Clinicians and the scientific community need evidence on the benefits and tolerance of exercise protocols available in clinical practice. The proposed trial will provide important and needed data on interval and continuous exercise for decision making in clinical practice
