Online Network Revenue Management Using Thompson Sampling
Authors: Ferreira Kris Johnson , Simchi-Levi David , Wang He
Published: November 2018

Thompson sampling is a randomized Bayesian machine learning method, whose original motivation was to sequentially evaluate treatments in clinical trials. In recent years, this method has drawn wide attention, as Internet companies have successfully implemented it for online ad display. In “Online network revenue management using Thompson sampling,” K. Ferreira, D. Simchi-Levi, and H. Wang propose using Thompson sampling for a revenue management problem where the demand function is unknown. A main challenge to adopt Thompson sampling for revenue management is that the original method does not incorporate inventory constraints. However, the authors show that Thompson sampling can be naturally combined with a linear program formulation to include inventory constraints. The result is a dynamic pricing algorithm that incorporates domain knowledge and has strong theoretical performance guarantees as well as promising numerical performance results. Interestingly, the authors demonstrate that Thompson sampling achieves poor performance when it does not take into account domain knowledge. Finally, the proposed dynamic pricing algorithm is highly flexible and is applicable in a range of industries, from airlines and internet advertising all the way to online retailing.
Wear performance of retrieved metal-on-metal Pinnacle hip arthroplasties implanted before and after 2007

Published: November 2018

Objectives

Previous studies have suggested that metal-on-metal (MoM) Pinnacle (DePuy Synthes, Warsaw, Indiana) hip arthroplasties implanted after 2006 exhibit higher failure rates. This was attributed to the production of implants with reduced diametrical clearances between their bearing surfaces, which, it was speculated, were outside manufacturing tolerances. This study aimed to better understand the performance of Pinnacle Systems manufactured before and after this event.

Methods

A total of 92 retrieved MoM Pinnacle hips were analyzed, of which 45 were implanted before 2007, and 47 from 2007 onwards. The ‘pre-2007’ group contained 45 implants retrieved from 21 male and 24 female patients, with a median age of 61.3 years (interquartile range (IQR) 57.1 to 65.5); the ‘2007 onwards’ group contained 47 implants retrieved from 19 male and 28 female patients, with a median age of 61.8 years (IQR 58.5 to 67.8). The volume of material lost from their bearing and taper surfaces was measured using coordinate and roundness measuring machines. These outcomes were then compared statistically using linear regression models, adjusting for potentially confounding factors.

Results

There was no significant difference between the taper and bearing wear rates of the ‘pre-2007’ and ‘2007 onwards’ groups (p = 0.67 and p = 0.39, respectively). Pinnacles implanted from 2007 onwards were revised after a mean time of 50 months, which was significantly earlier than the ‘pre-2007’ hips (96 months) (p < 0.001). A reduction in the time to revision was present year on year from 2003 to 2011.

Conclusion

We found no difference in the wear rate of these implants based on the year of implantation. The ‘pre-2007’ hips had a two-fold greater time to revision than those implanted after 2007; this may be due to the increased surveillance of MoM hips following UK regulatory advice and several high-profile failures. Interestingly, we observed a decreasing trend in the mean time to revision every year from 2003 onwards. Cite this article: S. Bergiers, H. S. Hothi, J. Henckel, A. Eskelinen, J. Skinner, A. Hart.

Published: November 2018

BACKGROUND

Cholesterol efflux capacity (CEC) is a measure of HDL function that, in cell-based studies, has demonstrated an inverse association with cardiovascular disease. The cell-based measure of CEC is complex and low-throughput. We hypothesized that assessment of the lipoprotein proteome would allow for precise, high-throughput CEC prediction.

METHODS

After isolating lipoprotein particles from serum, we used LC-MS/MS to quantify 21 lipoprotein-associated proteins. A bioinformatic pipeline was used to identify proteins with univariate correlation to cell-based CEC measurements and generate a multivariate algorithm for CEC prediction (pCE). Using logistic regression, protein coefficients in the pCE model were reweighted to yield a new algorithm predicting coronary artery disease (pCAD).

RESULTS

Discovery using targeted LC-MS/MS analysis of 105 training and test samples yielded a pCE model comprising 5 proteins (Spearman r = 0.86). Evaluation of pCE in a case–control study of 231 specimens from healthy individuals and patients with coronary artery disease revealed lower pCE in cases (P = 0.03). Derived within this same study, the pCAD model significantly improved classification (P < 0.0001). Following analytical validation of the multiplexed proteomic method, we conducted a case–control study of myocardial infarction in 137 postmenopausal women that confirmed significant separation of specimen cohorts in both the pCE (P = 0.015) and pCAD (P = 0.001) models.

CONCLUSIONS

Development of a proteomic pCE provides a reproducible high-throughput alternative to traditional cell-based CEC assays. The pCAD model improves stratification of case and control cohorts and, with further studies to establish clinical validity, presents a new opportunity for the assessment of cardiovascular health.
(In)visible ink: Outsiders at the Yaji, the ink installations of Bingyi and Tao Aimin
Authors: Guest Luise
Published: November 2018

The yaji in Imperial China was an ‘elegant gathering’ of scholars who met to play chess, listen to music, and appreciate ink painting and calligraphy. They were generally all-male affairs, often taking place in a walled garden. Recently it has been argued that such forms of semi-private contemplation are appropriate models for exhibiting Chinese contemporary art. This article has two connected parts: the first examines how two women artists, Tao Aimin and Bingyi, ‘outsiders’ to the yaji garden gathering as it was traditionally constructed, subvert (yet also honour) important Chinese traditions. They challenge a gendered historical narrative by means of a reinvigorated and performative ink language, negotiating literal and figurative ‘inside’ and ‘outside’ spaces. Positioned as reconfiguring space in a way that challenges binaries of inside/outside, they interrogate the literati tradition that functioned as an expression of class and gender. Two works in particular exemplify their practice: Bingyi’s Époché, a 2014 performance in which she dropped 500 kilograms of ink/oil ‘missiles’ from a helicopter over the airfield at Shenzhen Bao’an Airport, and Tao Aimin’s 2008 The Secret Language of Women, an installation of bound books printed from rural women’s washboards employing the ancient Nüshu script invented by rural women. The second part of the article critically examines contemporary iterations of the yaji as a model for the exhibition of contemporary art. The term yaji is thus used in two ways in this article: as a metaphor to reflect on the absence of women artists in the reinvented literati ink tradition, and in a critical examination of its real-world manifestations in several recent exhibitions. In this context, the works of Tao Aimin and Bingyi occupy a complicated liminal space: they position themselves at times inside feminist discourse and at other times disavow a connection; they occupy a marginal space within dominant contemporary art world discourses and historically masculine discourses around calligraphy and the yaji, yet ‘inside’ the ink tradition. This article was developed from a paper presented at the Annual Conference of the Centre for Chinese Visual Art, School of Art, Birmingham City University, 13 October 2017.
Village transformed: Jin Le and community development through contemporary art
Authors: Wang Meiqin
Published: November 2018

Drawing upon field research, this article examines the work of artist Jin Le who strives to engage his fellow villagers from the remote rural village Shijiezi in light of the growing desire among the contemporary Chinese art circles to seek alternative spaces for artistic production and to make art relevant to community development. Increasingly stricken by the gap between metropolises such as Beijing where he was based and the countryside such as Shijiezi where he grew up, Jin left Beijing in 2005 and has since endeavoured to introduce art as a stimuli for changes to his poverty-laden home village in both materialistic and cultural terms. His work includes making site-specific sculpture and installation works to enrich the public space in the village, taking villagers to participate in art-related events in the cities, inviting artists and other professionals to visit and interact with villagers, initiating projects for collaborations between art professionals and villagers, and facilitating the implementation of these collaborations, among others. Jin’s election to be the village head in 2008 by the villagers and their agreement to offer their private homes as ready-made exhibiting spaces so Shijiezi Museum could be found in 2009 testify to a certain level of efficacy of Jin’s socially engaged art practice. Building upon local support, Jin and his collaborator Qin Ga, a Beijing-based artist, launched the ambitious Fly Together: Shijiezi Village Art Practice Project in 2015. This one-year long collaborative project facilitates the collaboration of 25 artists and artist collectives and 25 local residents, resulting in many thought-provoking artworks and pragmatic outcomes as well as long-term collaborative relationships. Arguably, Jin’s effort highlights the potential of employing art for intersubjective communications, the growth of transformative relationships, and grassroots-initiated social changes, even at a small-scale and with limited resources.
Inside out: The remaking of home as an institution of critique
Authors: Gu Jiangtao
Published: November 2018

As the issue’s call for papers has rightly discerned, contemporary Chinese art utilized spaces outside of the art institution as the site of production and exhibition since its early developments. From the first Star Group exhibition in 1979 to Song Dong’s site-specific work in the 1990s, avant-garde Chinese artists have experimented with spaces that are parasitic or antithetic to the official spaces of the nation-state. Such practices might have successfully deconstructed the art institution and its symbolic orders in an earlier moment, they are nonetheless prone to the processes of institutionalization and canonization. This is especially true when museums, galleries and academics, together with market players, have claimed such spaces and artists as the place and subject of a new order known as ‘institutional critique’. Departing from this straightforward mode of institutional critique, this article identifies home as a critical space in contemporary Chinese art practices since the late 1990s and early 2000s. The production, exhibition and critique of art in China today. Joining what is known as the ‘third wave’ of institutional critique, this article reclaims what might constitute a new subject of cultural criticism precisely when state-sponsored art institutions are defunded and demolished by neo-liberal governments around the globe. Turning inside out, it reworks the dichotomy of interiority and exteriority as they are articulated by the bourgeois class to return art to that of the marginalized and disfranchised.
Independent spaces to the street: Participatory art in Shanghai
Authors: Chun Julie
Published: November 2018

The culture of accelerated museum building and promotion of contemporary art in Shanghai has created a spill-over effect in the upsurge of independent art spaces and self-organized artistic projects on the streets. Yet, participatory art in China that directly engages the viewers has its own prescriptions for ‘publicness’ that does not readily conform to western concepts of site-specificity or the public sphere. By foregrounding cross-disciplinary methods and years of primary field work, this research is a dedicated and vigilant observation of how a new generation of artists are incorporating the community as an integral aspect of their practice to expand the discourse of contemporary art in Shanghai. This article sets the context by providing a brief art historical evaluation of art outside museums and institutions as they emerged in the West and in China. Then, three contemporary case studies in Shanghai are examined to contend that artistic producers who recognise the shifting identities and needs of the public are interrogating the value and potentiality of socially engaging art to expand the cultural literacy for members of its community.

Published: November 2018

In the baking industry, continuous development of products is required because consumers with different nutritional needs are pushing for new requirements for food. Along with the low caloric content, there is growing attention to the functional effects of foods.

The aim of our work is the development of a matzo made of wholemeal rye flour, which helps in healthy nutrition for the customer’s and more economical from production’s point of view. The main aim of the product development in our project is to increase the nutrient content by the raise of mineral and fibre content.

In the first part of our work we performed basic measurements with flours used during product development. We measured the quantity and quality of gluten protein with Glutomatic-Gluten Index System, the activity of amylase enzymes with Falling Number 1400 and we did complex dough monitoring with METEFÉM Valorigraphe FQA 205. In the second part of our project we compare the basic matzo with matzos made of 3 different recipes. Based on results of examinations it can be ascertain that the Sample 2 shows more advantageous values of the fibre content’s and the prime cost’s point of view.
Dilemmas of Representation in Contemporary Environmental Anthropology: Documenting Dynamite Fishing in Southeastern Tanzania
Authors: Raycraft Justin
Published: November 2018

This paper draws from an ethnographic vignette of dynamite fishing in southeastern Tanzania. I consider the utility of participant observation as a method for examining ecologically destructive practices, especially in contexts where such activities are illegal or prohibited by conservation regulations. I raise self-reflexive critiques, internal to my home discipline of anthropology, and discuss the methodological, ethical, and analytical challenges of attempting to document cases of dynamite fishing and other related phenomena of pressing environmental concern. Ultimately, I maintain that participant observation remains a valuable tool for documenting and explaining environmentally destructive activities.

Floral opening stage during harvest and use of postharvest techniques, such as inflorescence coating with carnauba wax, may influence quality maintenance for commercialization. The aim was to evaluate the carbohydrate content of torch ginger inflorescences harvested at two different opening stages and treated with different concentrations of carnauba wax. The inflorescences were harvested with semi-open (basal bracts beginning their expansion process) and open bracts (fully expanded basal bracts and opening of the smaller bracts on interior of the inflorescence) and received the application of carnauba wax at concentrations of 0.75%; 1.5% or 3.0%, in addition to a control treatment, without wax application. After the treatment, the floral stems were maintained at 16 and 21 oC for 20 days. During the storage period, five bracts samples (external and internal bracts separately - in open inflorescences, external and internal bracts together - in semi-open inflorescences) were carried out every three days for evaluation of total soluble sugars and starch content. Contents of total soluble sugars and starch differed between the different types of bracts collected and throughout the storage period evaluated, and could indicate a remobilization of reserves. The concentration of 3.0% carnauba waxinduced higher total soluble sugar content. However, this content does not affect the longevity of torch ginger at the two evaluated floral opening stages.

The weathering mechanism of rocks exposed under the same conditions on the Bamenda Mountain is not well understood. The aim of this study is to characterize basalt, trachyte and rhyolite and their products on the geochemical and geotechnical aspect. Here three wells were hand dug on rocks developed on basalt, trachyte and rhyolite and studied. The results showed that, Ki values (0.34-6.57) indicate SiO2 are more leached on soils developed on basalt than those on trachyte and rhyolite. CIA (72.62-97.8) and CIW (72.76-98.8) indicate an advanced to extreme chemical weathering in this environment, with rhyolite and trachyte more weathered than basalts. Soils formed on basalt have ICV >1 signifying they are young and immature, while those on trachyte and rhyolite ICV =0.3-0.5 indicate intense chemical weathering. Al (EFAl=1.5) and Fe (EFFe=1.3) are enriched in the soils and while SiO2, Na, K, Ca and Mg are depleted in the soils profile as one moves upward. Geotechnically, these soils are predominantly silts, well graded, less plastic (LI<0), plastic (CI>1) to moderately plastic (PI=7.2-15.8). Soils developed on rhyolite have high clay content MBV= 3.3-8, but low water content (10-42%). Texturally, these soil are silty loam, loam to sandy loam soils. Soil strength of the soils is low: cohesion (<0.5bar), angle of internal friction (10-43°), with shallow landslides (1-2m) more likely to occur on trachyte and on rhyolites.

Published: November 2018

Toxic metal contamination is a major problem globally, especially in developing countries. In this study, the levels of toxic metals such as Cr, Ni, Cu, As, Cd and Pb in surface water and sediment of Korotoa River of Bogra City, Bangladesh were investigated. The average concentration of Cr, Ni, Cu, As, Cd and Pb in studied sediment were 1.01, 0.89, 1.98, 6.02, 0.0054 and 0.469 mg/kg, respectively. In the water sample, the mean concentration of Cr, Ni, Cu, As, Cd and Pb were 1.13, 1.33, 3.02, 2.62, 0.75 and 0.81 mg/kg, respectively. A huge amount of municipal wastes, industrial effluents and agricultural runoff from the periphery of Bogra City notably are dumped to this river. Most of the effluents channeled into these rivers are not treated. Considering the sampling sites, the decreasing order of total metal concentration in water samples were Cu > As > Ni > Cr > Pb > Cd and in sediment were As > Cu > Cr> Ni > Pb > Cd. Total average concentrations of Cr, Ni, Cu, As, Cd and Pb in the water samples were higher than WHO guidelines for drinking water quality. This contamination level implied that the condition is much frightening and probably severely affecting the aquatic ecology of the river.

In the last decades, power grids and other energy transmission networks have received attention from the network literature. In this work, we studied one of the most important static features of power grids, their topology, with focus on the Brazilian Power Grid (BPG). We obtained the spatial structure of the BPG from the ONS (Electric System National Operator), consisting of its high-voltage transmission lines, electric stations and substations. Some traits had to be ignored, such as the local low-voltage substations and as well the dynamic features of the network. We analyzed the complex network of the BPG and its statistics, such as the mean degree, the degree distribution, the network size and the clustering coefficient to characterize the complex network. We also detected critical locations in the network and, therefore, points that are more susceptible to cascading failures and even to blackouts. Our results show that the BPG is functional against random failures, regarding random removal of links and connections, in terms of the size of the largest cluster. We observe that when a fraction ρ of the links are randomly removed, the network may break down into smaller, disconnected parts. However, the largest component of the power grid remains connected. We believe that even a static study of the network topology can help to identify the critical situations and also prevent failures and possible blackouts.
The Cambridge and the Exeter Book Physiologi: Associative Imagery, Allegorical Circularity, and Isidorean Organization
Authors: Salvador-Bello Mercedes , Gutiérrez-Ortiz Mar
Published: November 2018

The Physiologus has survived in some twenty-four manuscripts, two of which are of English origin: Cambridge, Corpus Christi College, 448, and Exeter, Cathedral Library, 3501. The latter codex, also known as the Exeter Book, contains a verse Physiologus (fols. 95v–98r) in Old English. In turn, the Cambridge manuscript provides a Latin prose Physiologus (fols. 88r–89r). These two texts bear witness to the knowledge of the Physiologus in the late Anglo-Saxon period and constitute the central piece of evidence extant for the dissemination of this work in England. Even though the two versions are formally and stylistically different, the manuscripts in which they occur are roughly contemporary and both of them are of Southern provenance. Each of these Physiologi comprises three chapters describing three animals: lion, unicorn and panther in the case of the Cambridge Physiologus, and panther, whale and an unknown bird – whose identification is problematic due to a textual gap – in the Exeter codex. Despite these striking affinities, no scholarly work has offered a comparative study of the two Physiologi, with the exception of Andrea Rossi-Reder’s unpublished PhD dissertation (1992), and only passing reference has been made to the Cambridge Physiologus in discussions of the better‑known Exeter text.

In order to remedy this critical neglect, the present article offers a detailed analysis of both Physiologi, together with a first edition of the Latin text. As we will show, the Cambridge and the Exeter Physiologi share the same cultural background and apply similar compilation criteria. In both cases, the zoological motifs were selected according to organizational principles based on Isidore’s Etymologiae, such as the animals’ unclean character and size. In both, too, the creatures described are interconnected by means of recurrent associative imagery and an allegorical circular design. This combination of encyclopedic criteria and the sensory characterization of the animals discloses remarkable parallelisms in the structure and the compositional technique of these two Physiologi. Moreover, this analogous organizational method offers additional evidence to support Michael D. C. Drout’s hypothesis that the bird described in the fragmentary third chapter of the Exeter version is the phoenix instead of the partridge, as some other scholars had traditionally maintained. Our reading also effectively harmonizes with the eschatological and anagogic elements which have been pointed out for the third chapter of the Exeter Physiologus, as well as with the allegorical and tropological roles of the panther and the whale.
Binding by objects in Polish docs and please-type double object unaccusatives: Testing theoretical accounts
Authors: Gogłoza Aleksandra , Łęska Paulina
Published: November 2018

Our paper focuses on binding relations in the Polish piacere-type psychological verb podobać się ‘to please’. In particular, we aim to test the make-up of the argument structure of this verb, which is taken in the literature to be of a double object unaccusative verb (Belletti and Rizzi 1988; Miechowicz-Mathiasen and Scheffler 2008; Jiménez-Fernández and Rozwadowska 2016; a.o.). To this end, we conduct an experimental study, which examines the ability of pre-verbally spelled-out NOM and DAT arguments of podobać się to bind possessive pronouns/reflexives. As a point of reference, we use the results of our previous study on binding relations in Polish double object constructions (DOCs). The study revealed that the higher object, in [Spec;VP], can bind only a possessive pronoun, and not a possessive reflexive embedded in the lower object. The results of our present study display analogous binding relations in podobać się, which provides an argument in favor of the double object unaccusative structure of this verb. Based on our results, we advance a theoretical account of binding in podobać się, which assumes the Index Theory of Binding (Hestvik 1992; Nikolaeva 2014) together with a slightly modified version of a recent analysis of podobać się put forward in Jiménez-Fernández and Rozwadowska (2016).
Zippeite from Cap Garonne, France: an example of reticular twinning

Published: November 2018

We describe here the case of twinning by reticular (pseudo)merohedry in case of natural zippeite crystal from Cap Garonne, France. The twin is by two-fold rotation in [100] and it is a first document of this type of twinning in zippeite-related minerals and compounds. Zippeite crystals from Cap Garonne mine, France, were studied by single-crystal X-ray diffraction [a=8.7243(4), b=13.9337(7), c=8.8741(4) Å, β=104.243(5) and V=1045.59(9) Å3, Z=2, in C2/m]; refinement taking into account of the twinning resulted in R=2.81% for 1596 reflections with [I>3σ(I)] and refined twin fraction 0.7773(9):0.2227(9).
Running Wild: engaging and empowering future custodians of place through creative nature-based play
Authors: Beer Tanja , Cook Andrea , Kantor Kate
Published: November 2018

Children are spending significantly less time in nature than ever before. The decline in nature-based play has been precipitated by many factors, including: increased risk aversion and fear amongst parents, poor play opportunities for children and the rapid embrace of digital technology as recreation by young people. These factors all contribute to a collective and individual loss of childhood experience with nature. At the same time, young people are increasingly aware of the unprecedented level of climate change, pollution, habitat destruction and species extinction and the effect it could have on their futures. Thus, there is an urgent need for new approaches to environmental learning that celebrates children’s agency, supporting them to directly contribute to ecological systems and global sustainability across communities. This paper explores the potential of creative nature-based play to contribute to children’s identity and understanding of the natural world through a practice-led research project, Running Wild (2016). Running Wild was conducted with Polyglot Theatre in collaboration with Year 6 students from Mahogany Rise Primary School (Frankston North) and the Royal Botanic Gardens (Cranbourne). The aim of the project was to introduce the students to their natural reserve (‘The Pines’) through participatory art-making in collaboration with local artists, scientists and Indigenous elders. This included the opportunity for children to build their own habitats or ‘cubbies’, make animal costumes and plant native seedlings at The Pines, resulting in an outdoor performance for their families and friends. Running Wild not only demonstrated increased nature-connection amongst the students, but also the importance of creative nature-based play in improving learning capacities and wellbeing, as well as promoting opportunities for environmental leadership.

A Gate-and-Switch Model for Head Orientation Behaviors inCaenorhabditis elegans
Authors: Ouellette Marie-Hélène , Desrochers Melanie J. , Gheta Ioana , Ramos Ryan , Hendricks Michael
Published: November 2018

The nervous system seamlessly integrates perception and action. This ability is essential for stable representation of and appropriate responses to the external environment. How the sensorimotor integration underlying this ability occurs at the level of individual neurons is of keen interest. InCaenorhabditis elegans, RIA interneurons receive input from sensory pathways and have reciprocal connections with head motor neurons. RIA simultaneously encodes both head orientation and sensory stimuli, which may allow it to integrate these two signals to detect the spatial distribution of stimuli across head sweeps and generate directional head responses. Here, we show that blocking synaptic release from RIA disrupts head orientation behaviors in response to unilaterally presented stimuli. We found that sensory encoding in RIA is gated according to head orientation. This dependence on head orientation is independent of motor encoding in RIA, suggesting a second, posture-dependent pathway upstream of RIA. This gating mechanism may allow RIA to selectively attend to stimuli that are asymmetric across head sweeps. Attractive odor removal during head bends triggers rapid head withdrawal in the opposite direction. Unlike sensory encoding, this directional response is dependent on motor inputs to and synaptic output from RIA. Together, these results suggest that RIA is part of a sensorimotor pathway that is dynamically regulated according to head orientation at two levels: the first is a gate that filters sensory representations in RIA, and the second is a switch that routes RIA synaptic output to dorsal or ventral head motor neurons.
