Authors: Lakshmanan S. , Holmes W. M. , Sloan W. T. , Phoenix V. R. 
Published: February 2015

AbstractMagnetic resonance imaging (MRI) has tremendous potential for revealing transport processes in engineered and geologic systems. Here, we utilize MRI to image nanoparticle (NP) transport through a saturated coarse-grained system. Commercially available paramagnetically tagged NPs are used; the paramagnetic tag making the NP visible to MRI. NP transport was imaged as NPs migrated through packed columns of quartz and dolomite gravel. Changes in T2-weighted image intensity were calibrated to provide fully quantitative maps of NP concentration at regular time intervals (T2being the spin–spin relaxation time of1H nuclei). Transport of nanoparticles was significantly retarded in dolomite compared to quartz due to electrostatic attraction between nanoparticle and dolomite surfaces. NP concentration profiles were evaluated with the CXTFIT computer package to estimate nanoparticle transport parameters at multiple points along the length of the column. This provided temporally resolved parameters that standard breakthrough curve analysis cannot provide. Particle–surface interaction energy profiles were described through Derjaguin-Landau-Verwey-Overbeek (DLVO) theory. While dispersion coefficients and fast deposition rate constant (kfast) were found to increase with distance, deposition rate constant (k) and collision efficiency (α) were found to decrease with distance. These length-dependant variations have significant scaling-up implications for transport models used to predict NP transport in natural and engineered coarse-grained systems, such as sustainable urban drainage systems and river beds.

To our knowledge, no study has assessed the relationships between patterns of dietary behaviours, identified by latent class analysis (LCA), and chronic uninvestigated dyspepsia (CUD). The present study was conducted to determine the association between the patterns of dietary behaviours, identified by LCA, and CUD in a large sample of adults. In a cross-sectional study conducted on 4763 Iranian adults, we assessed the patterns of dietary behaviours in four domains, including ‘meal patterns’, ‘eating rate’, ‘intra-meal fluid intake’ and ‘meal-to-sleep interval’, as identified by LCA, using a pre-tested comprehensive questionnaire. Patients with CUD were identified using the Rome III diagnostic criteria. CUD was prevalent in 15·2 % (95 % CI 14·4, 16·2 %; n 723) of patients. Early satiation occurred in 6·3 % (n 302) of patients, bothersome postprandial fullness in 8·0 % (n 384) of patients and epigastric pain in 7·8 % (n 371) of patients. We defined two distinct classes of meal patterns: ‘regular’ and ‘irregular’. For eating rates, three classes were defined: ‘moderate’, ‘moderate-to-slow’ and ‘moderate-to-fast’. Participants were identified as ingesting fluid with meals in two major classes: ‘moderate intra-meal drinking’ and ‘high intra-meal drinking’. In terms of the interval between meals and sleeping, two distinct classes were identified: ‘short meal-to-sleep interval’ and ‘long meal-to-sleep interval’. After controlling for potential confounders, the ‘irregular meal pattern’ was significantly associated with a greater odds of CUD (OR 1·42, 95 % CI 1·12, 1·78) compared with a ‘regular meal pattern’. Individuals with a ‘moderate-to-fast eating rate’ were more likely to have CUD compared with those who had a ‘moderate eating rate’ (OR 1·42, 95 % CI 1·15, 1·75). Patterns of the ‘meal-to-sleep interval’ and ‘intra-meal fluid intake’ were not significantly associated with CUD. In conclusion, the ‘irregular meal pattern’ and the ‘moderate-to-fast eating rate’ were significantly associated with a greater odds of CUD. Further prospective investigations are warranted to confirm this association.
Strangers in the Village? Colonial policing in rural Bengal, 1861 to 1892
Authors: GIULIANI ERIN M. 
Published: February 2015

AbstractThe chief concern of this article is the organization and administration of rural policing in colonial Bengal during the last 40 years of the nineteenth century. It connects its design and implementation with the consolidation of India's colonial police force, while highlighting the ongoing negotiations made by the Bengal police in a wider colonial model. The article argues that the police administration of rural Bengal was shaped initially by the ordinary constraints of the colonial state which underpinned the design of the Indian police—namely its frugality and preference for collaborating with local intermediaries, a manifestation of salutary neglect. Yet, it highlights the role of Bengal's largely British police executive in renegotiating customs of governance and, ultimately, as an established model of policing in India. The article focuses, therefore, on ongoing and at times informal police reforms which were based upon notions contradictory to an official discourse about policing in India. This article thus contextualizes the development of rural police administration in Bengal in a strong tradition of police-led reform in the province. In so doing, the article redresses a traditional historiographical focus on the political origins and coercive function of the police, and problematizes current research which situates Indian policing within customs of British governance in the subcontinent.

Published: February 2015

BackgroundIt is unclear if the impact of psychoeducational family intervention for patients with schizophrenia can be sustained over 10 years. In this study, we explored the 14-year effect of psychoeducational family intervention for patients with schizophrenia in a Chinese rural area.MethodThe data from a cluster randomized control trial (CRCT) study of psychoeducational family intervention in a 14-year follow-up was analyzed. All patients with schizophrenia (n = 326) who participated in the CRCT drawn from six townships in Xinjin County of Chengdu in 1994, of whom 238 (73.0%) who were still alive, and their informants were followed up in 2008. The Patients Follow-up Scale, the Positive and Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning were used in the follow-up study.ResultsThere were no significant differences of marital status, mean scores of PANSS positive symptoms, negative symptoms, general mental health, and total scores among the psychoeducational family intervention, medication, and control groups in 2008. The psychoeducational family intervention group had a significantly higher rate of antipsychotic medication and a higher level of work ability than other two groups. The control group had a significantly higher rate of never-treated (26.0%) than psychoeducational family intervention group (6.5%).ConclusionPsychoeducational family intervention might be still effective in the 14-year follow-up, especially in patients’ treatment adherence/compliance and social functioning. Psychoeducational family intervention might be more effective in places where family members frequently participated in patients’ care and had a lower level of knowledge on mental illness. Family intervention should be considered when making mental health policy and planning mental health services.
THE SIXTEEN-FOOTVIOLONEIN CONCERTED MUSIC OF THE SEVENTEENTH AND EIGHTEENTH CENTURIES: ISSUES OF TERMINOLOGY AND FUNCTION
Authors: CHAPMAN DAVID F. 
Published: February 2015

ABSTRACTRecent performance projects have called into question the use of the sixteen-footviolonein a wide range of instrumental and concerted vocal works, particularly those by J. S. Bach. In performances of music by Bach and his contemporaries, artists have on occasion opted to exclude sixteen-foot participation in the bass line, often citing terminological issues as a reason. While acknowledging that the use of the termviolonein scores and parts from the sixteenth to the eighteenth centuries is problematic, this article casts doubt on the conclusions reached by these performers and on the scholarly writings underpinning them. A careful examination of instrumental designations employed in autograph parts and scores provides important clues as to the proper employment of a sixteen-foot contrabass instrument in many works. Further illumination on this matter is provided by terminology in contemporary treatises. Analysis of this material shows that the function of the bass line to which the termviolone(or any of its regional variants) was assigned was a crucial determining factor in interpreting that part as either an eight- or sixteen-foot bass line. In other words, modern determinations should be made according to whether the designation indicates a non-transposing instrument serving primarily as the bass member of an instrumental choir or a transposing instrument whose main purpose is reinforcing the continuo line at the lower octave.
BLAINVILLE'S NEW MODE, OR HOW THE PLAGAL CADENCE CAME TO BE ‘PLAGAL’
Authors: MUTCH CALEB 
Published: February 2015

ABSTRACTThe plagal cadence has long been a significant concept within musical discourse, but that discourse contains no convincing explanation of why the progression should be characterized as ‘plagal’. This article elucidates the meaning of the term ‘plagal cadence’ by examining its introduction into a mid-eighteenth-century Parisian debate over the nature of what would come to be called tonality instigated by Charles-Henri de Blainville's proposal of the ‘mixed mode’, a supplement to the major and minor modes. Owing to the properties of his new mode's scale, which corresponds to the Phrygian mode, Blainville identified the plagal cadence as the proper conclusion for pieces in the mixed mode. Curiously, although Blainville's work appears to contain the first published articulation of the term, he employs it as if his readers were already familiar with the ‘plagal cadence’. This article explains that oddity, finding that Blainville misread earlier accounts of plainchant as saying that plagal modes were characterized by the interval of the descending fourth. In conclusion, consideration of the controversy regarding the mixed mode and plagal cadence reveals that those historical disagreements bear striking similarities to current debates over the significance and function of the plagal cadence in theories of harmony.
Reversible monolayer-to-crystalline phase transition in amphiphilic silsesquioxane at the air-water interface

Published: February 2015

AbstractWe report on the counter intuitive reversible crystallisation of two-dimensional monolayer of Trisilanolisobutyl Polyhedral Oligomeric SilSesquioxane (TBPOSS) on water surface using synchrotron x-ray scattering measurements. Amphiphilic TBPOSS form rugged monolayers and Grazing Incidence X-ray Scattering (GIXS) measurements reveal that the in-plane inter-particle correlation peaks, characteristic of two-dimensional system, observed before transition is replaced by intense localized spots after transition. The measured x-ray scattering data of the non-equilibrium crystalline phase on the air-water interface could be explained with a model that assumes periodic stacking of the TBPOSS dimers. These crystalline stacking relaxes upon decompression and the TBPOSS layer retains its initial monolayer state. The existence of these crystals in compressed phase is confirmed by atomic force microscopy measurements by lifting the materials on a solid substrate.
A General Design Rule to Manipulate Photocarrier Transport Path in Solar Cells and Its Realization by the Plasmonic-Electrical Effect

Published: February 2015

AbstractIt is well known that transport paths of photocarriers (electrons and holes) before collected by electrodes strongly affect bulk recombination and thus electrical properties of solar cells, including open-circuit voltage and fill factor. For boosting device performance, a general design rule, tailored to arbitrary electron to hole mobility ratio, is proposed to decide the transport paths of photocarriers. Due to a unique ability to localize and concentrate light, plasmonics is explored to manipulate photocarrier transport through spatially redistributing light absorption at the active layer of devices. Without changing the active materials, we conceive a plasmonic-electrical concept, which tunes electrical properties of solar cells via the plasmon-modified optical field distribution, to realize the design rule. Incorporating spectrally and spatially configurable metallic nanostructures, thin-film solar cells are theoretically modelled and experimentally fabricated to validate the design rule and verify the plasmonic-tunable electrical properties. The general design rule, together with the plasmonic-electrical effect, contributes to the evolution of emerging photovoltaics.
Characterizing spatial distributions of astrocytes in the mammalian retina
Authors: Jammalamadaka Aruna , Suwannatat Panuakdet , Fisher Steven K. , Manjunath B. S. , Höllerer Tobias , Luna Gabriel 
Published: February 2015

AbstractMotivation: In addition to being involved in retinal vascular growth, astrocytes play an important role in diseases and injuries, such as glaucomatous neuro-degeneration and retinal detachment. Studying astrocytes, their morphological cell characteristics and their spatial relationships to the surrounding vasculature in the retina may elucidate their role in these conditions.Results: Our results show that in normal healthy retinas, the distribution of observed astrocyte cells does not follow a uniform distribution. The cells are significantly more densely packed around the blood vessels than a uniform distribution would predict. We also show that compared with the distribution of all cells, large cells are more dense in the vicinity of veins and toward the optic nerve head whereas smaller cells are often more dense in the vicinity of arteries. We hypothesize that since veinal astrocytes are known to transport toxic metabolic waste away from neurons they may be more critical than arterial astrocytes and therefore require larger cell bodies to process waste more efficiently.Availability and implementation: A 1/8th size down-sampled version of the seven retinal image mosaics described in this article can be found on BISQUE (Kvilekval et al., 2010) at http://bisque.ece.ucsb.edu/client_service/view?resource=http://bisque.ece.ucsb.edu/data_service/dataset/6566968.Contact: arunaj@ece.ucsb.edu or manj@ece.ucsb.eduSupplementary information: Supplementary data are available at Bioinformatics online.
Social learning augmented by social media: creating better organizations for a better world
Authors: L. Conner Marcia 
Published: February 2015

Purpose
– Social media provides a modern approach to working and learning with people across vast distances as easily as if they were side by side. The new tools foster a new type of social learning, offering leaders an opportunity to transform their organizations into rich learning labs where new knowledge and innovative practices emerge in real-time.

Design/methodology/approach
– Based on my book published in 2010, and the work I have done with more than 100 companies on social media’s use for fostering social learning.

Findings
– Social technologies should be used to replace outmoded education programs with more effective and mobile means. With these tools, learners can reframe learning from a passive activity done to learners to an active and very human activity that enables people to build upon their individual and collective potential.

Originality/value
– Written for this publication, yet based on the learnings since and research done originally for The New Social Learning.

New roles and challenges within the healthcare workforce: a Heideggerian perspective
Authors: Wilson Anthea 
Published: February 2015

Purpose
– The purpose of this paper is to explore insights based on the phenomenology of Martin Heidegger, on the dynamic relationships between human experience and work roles.

Design/methodology/approach
– Drawing on the findings of a hermeneutic phenomenological study of nurse mentors, the topics of new roles and role challenges are explored, along with a consideration of their relevance to wider issues of workforce redesign. Heidegger’s philosophy of Dasein, in particular his concepts of inauthentic and authentic self, provided an interpretational lens. This paper applies these philosophical concepts to challenges associated with a changing workforce.

Findings
– Concepts elaborating human existence as proposed by Heidegger may offer analytic structures for understanding shifts in the lived experience of a changing workplace. In particular, the concepts could help managers to explore the implications of introducing novel work roles or extending roles. The understanding gained can also extend to situations where work practices may need to be challenged.

Originality/value
– As work roles and skill mix undergo rapid shifts, this paper offers an original way of understanding the experience of work roles.
Bottleneck-based opportunistic maintenance model for series production systems
Authors: Zhou Binghai , Yu Jiadi , Shao Jianyi , Trentesaux Damien 
Published: February 2015

Purpose
– The purpose of this paper is to develop a bottleneck-based opportunistic maintenance (OM) model for the series production systems with the integration of the imperfect effect into maintenance activities.

Design/methodology/approach
– On the analysis of availability and maintenance cost, preventive maintenance (PM) models subjected to imperfect maintenance for different equipment types are built. And then, a cost-saving function of OM is established to find out an optimal OM strategy, depending on whether the front-bottleneck machines adopt OM strategy or not. A numerical example is given to show how the proposed bottleneck-based OM model proceeded.

Findings
– The simulation results indicate that the proposed model is better than the methods to maintain the machines separately and the policy to maintain all machines when bottleneck machine reaches its reliability threshold. Furthermore, the relationship between OM strategy and corresponding parameters is identified through sensitivity analysis.

Practical implications
– In practical situations, the bottleneck machine always determines the throughput of the whole series production system. Whenever a PM activity is carried out on the bottleneck machine, there will be an opportunity to maintenance other machines. Under such circumstances, findings of this paper can be utilized for the determination of optimal OM policy with the objective of minimizing total maintenance cost of the system.

Originality/value
– This paper presents a bottleneck-based OM optimization model with the integration of the imperfect effect as a new method to schedule maintenance activities for a series production system with buffers. Furthermore, to the best of the knowledge, this paper presents the first attempt to considering the bottleneck constraint on system capacity and diverse types of machines as a means to minimize the maintenance cost and ensure the system throughput.

Published: February 2015

Purpose– The purpose of this paper is to propose a multi-variable analysis (MVA) model for predicting potential delays in the delivery of subsea inspection, maintenance and repair (IMR) services.Design/methodology/approach– Based on data from 351 subsea IMR service jobs executed between 2006 and 2008, a MVA model is proposed for predicting the potential delays in the delivery of IMR services in different plausible scenarios.Findings– A model for predicting the delays in IMR service delivery, based on four practical variables that are readily available during the planning phase, was developed and tested. The factors contributing to delays in petroleum subsea IMR services based on importance are: water depth, weather, job complexity, job uncertainty as well as job complexity mix.Research limitations/implications– The MVA model is developed based on analyzing subsea IMR service jobs performed in the petroleum industry from 2006-2008. The model can be used in the planning stage to predict potential delays in service delivery based on practical variables available.Originality/value– The research proposes a MVA model for predicting delays in service delivery. The model is useful for predicting potential delays in service delivery and for improving the plan based on model analysis results.

Authors: Kendell Ashley E. , Fleischman Julie M. , Fulginiti Laura C. 
Published: February 2015

AbstractWithin the context of medical examiner's offices, forensic anthropologists are increasingly being asked to assist with the interpretation of traumatic skeletal injury. This case study presents an example of trauma analysis performed by forensic anthropologists at the Maricopa County Forensic Science Center in Phoenix, Arizona. The primary goal of this study is to document an uncommon pattern of traumatic injury—severe grinding abrasions of the lower appendage that macroscopically resemble sharp force trauma, especially as observed in dismemberment cases—resulting from an individual being dragged beneath a Light Rail train for c. 1.7 miles. The abraded skeletal elements include a femoral shaft fragment, a femoral head portion, and the right foot. Second, this study aims to illustrate the efficacy of forensic anthropological analysis of patterned skeletal trauma. Finally, this study demonstrates the critical importance of analyzing scene information before drawing conclusions as to the etiology of a traumatic injury pattern.
