Published: December 2017

BACKGROUNDUpdated knowledge of the palliative care (PC) literature is needed to maintain competency and best address the PC needs of hospitalized patients. We critiqued the recent PC literature with the highest potential to impact hospital practice.METHODSWe reviewed articles published between January 2016 and December 2016, which were identified through a handsearch of leading journals and a MEDLINE search. The final 9 articles selected were determined by consensus based on scientific rigor, relevance to hospital medicine, and impact on practice.RESULTSKey findings include the following: scheduled antipsychotics were inferior to a placebo for nonterminal delirium; a low‐dose morphine was superior to a weak opioid for moderate cancer pain; methadone as a coanalgesic improved high‐intensity cancer pain; many hospitalized patients on comfort care still receive antimicrobials; video decision aids improved the rates of advance care planning (ACP) and hospice use and decreased costs; standardized, PC‐led intervention did not improve psychological outcomes in families of patients with a chronic critical illness; caregivers of patients surviving a prolonged critical illness experienced high and persistent rates of depression; people with non‐normative sexuality or gender faced additional stressors with partner loss; and physician trainees experienced significant moral distress with futile treatments.CONCLUSIONSRecent research provides important guidance for clinicians caring for hospitalized patients with serious illnesses, including symptom management, ACP, moral distress, and outcomes of critical illness.
Incremental Upper Bound for the Maximum Clique Problem
Authors: Li Chu-Min , Fang Zhiwen , Jiang Hua , Xu Ke 
Published: December 2017

The maximum clique problem (MaxClique for short) consists of searching for a maximum complete subgraph in a graph. A branch-and-bound (BnB) MaxClique algorithm computes an upper bound of the number of vertices of a maximum clique at every search tree node, to prune the subtree rooted at the node. Existing upper bounds are usually computed from scratch at every search tree node. In this paper, we define an incremental upper bound, called IncUB, which is derived efficiently from previous searches instead of from scratch. Then, we describe a new BnB MaxClique algorithm, called IncMC2, which uses graph coloring and MaxSAT reasoning to filter out the vertices that do not need to be branched on, and uses IncUB to prune the remaining branches. Our experimental results show that IncMC2 is significantly faster than algorithms such as BBMC and IncMaxCLQ. Finally, we carry out experiments to provide evidence that the performance of IncMC2 is due to IncUB. The online supplement is available at https://doi.org/10.1287/ijoc.2017.0770 .
Learning to Hire? Hiring as a Dynamic Experiential Learning Process in an Online Market for Contract Labor
Authors: Leung Ming D. 
Published: December 2017

We know a job applicant’s social category affects an employer’s likelihood of hiring the applicant, but we do not know whether, or how, employers update their beliefs regarding these social categories. I portray hiring as a cognitive decision and examine how prior negative and positive hiring experiences of employees from particular countries affect an employer’s subsequent likelihood of hiring applicants from those countries. I hypothesize that employer reactions will reflect loss aversion—that employers will react more strongly to negative hiring experiences than positive ones. Furthermore, I expect that the similarity of the prior job will moderate this effect. Analyses of 3.9 million applications, from freelancers worldwide, for over 290,000 jobs on an online labor market demonstrate that employers are 15% less likely (versus 8% more likely) to hire freelancers from a country following a prior negative (versus positive) experience. Prior negative experiences with similar jobs (versus dissimilar jobs) lead employers to be 82% less likely (versus 8% less likely) to hire from that country. Conversely, positive experiences with similar jobs (versus dissimilar jobs) lead employers to be 25% more likely (versus 3% more likely) to subsequently hire from that country. The consequences for switching countries, following negative experiences, are analyzed and wage differences to compensate for employer reactions, are calculated. Contributions to the hiring discrimination, impression formation, and gig-economy literatures are discussed. This paper was accepted by Olav Sorenson, organizations.
Financing Capacity Investment Under Demand Uncertainty: An Optimal Contracting Approach
Authors: de Véricourt Francis , Gromb Denis 
Published: December 2017

We study the capacity choice problem of a firm whose access to capital is hampered by financial frictions (i.e., moral hazard). The firm optimizes both its capacity investment under demand uncertainty and its sourcing of funds from a competitive investor. Ours is the first study of this problem to adopt an optimal contracting approach: feasible sources of funds are derived endogenously from fundamentals and include standard financial claims (debt, equity, convertible debt, etc.). Thus, in contrast to most of the literature on financing capacity investments, our results are robust to a change of financial contract. We characterize the optimal capacity level under optimal financing. First, we find conditions under which a feasible financial contract exists that leads to the first-best capacity. When no such contract exists, we find that under optimal financing, the choice of capacity sometimes exceeds strictly the efficient level. Furthermore, the firm invests more when its cash is low, and in some cases less when the project’s unit revenue is high. These results run counter to the newsvendor logic and standard finance arguments. We also show that our main results hold in the case of a strategic monopolist investor, and such an investor may invest more then a competitive one.

Estimation of Infiltration and Hydraulic Resistance in Furrow Irrigation, with Infiltration Dependent on Flow Depth
Authors: Bautista Eduardo , Schlegel James L. 
Published: December 2017

Abstract. Estimation of infiltration and hydraulic resistance model parameters from furrow irrigation evaluation data was investigated. A semi-physical, flow-depth dependent furrow infiltration model was used for the analysis. Macropore infiltration was modeled empirically as a constant volume of water per unit area that is absorbed instantaneously. The estimated infiltration parameters were the saturated hydraulic conductivity and the macropore constant. Hydraulic resistance was modeled with the Manning equation; thus, the estimated resistance parameter was the Manning coefficient. The estimation procedure uses volume balance calculations and unsteady flow simulation. Estimation of the flow-depth dependent infiltration parameters requires first the estimation of an empirical infiltration function, via volume balance, and of the resistance parameter, via unsteady flow simulation. Simulated flow depth hydrographs as a function of distance are then used as inputs for a second set of volume balance calculations with the semi-physical infiltration model. This procedure takes advantage of the fact that similar surface flow conditions (advance and recession times, flow depths, and runoff rate) can be predicted with different infiltration functions. The procedure was tested with two irrigation data sets, each consisting of three furrows. With both data sets, the semi-physical infiltration model fitted the measured volume balance data as well as empirical infiltration models. For each group of furrows, estimates of the hydraulic conductivity were of comparable magnitude and were consistent with published values for the particular soil texture. Likewise, estimates of the macroporosity parameter were consistent for each group of furrows. Estimates of the Manning coefficient suggest very uniform hydraulic resistance. Finally, results show that the effect of flow-depth dependent infiltration on irrigation distribution uniformity depends on soil and hydraulic conditions. For one of the data sets, distribution uniformity computed with the proposed infiltration model was only slightly different from the uniformity computed assuming that infiltration depends only on opportunity time, because of the large macropore flow contribution and the shallow flow conditions.

Published: December 2017

Abstract. Interest in cover crops has been increasing in the Texas Rolling Plains (TRP) region, mainly to improve soil health. However, there are concerns that cover crops could potentially reduce soil water and thereby affect the yield of subsequent cash crops. Previous field studies from this region have demonstrated mixed results, with some showing a reduction in cash crop yield due to cover crops and others indicating no significant impact of cover crops on subsequent cotton fiber yield. The objectives of this study were to (1) evaluate the CROPGRO-Cotton and CERES-Wheat modules within the cropping system model (CSM) of the Decision Support System for Agrotechnology Transfer (DSSAT) for the TRP region, and (2) use the evaluated model to assess the long-term effects of growing winter wheat as a cover crop on water balances and seed cotton yield under irrigated and dryland conditions. The two DSSAT crop modules were calibrated using measured data on soil water and crop yield from four treatments: (1) irrigated cotton without a cover crop (CwoC-I), (2) irrigated cotton with winter wheat as a cover crop (CwC-I), (3) dryland cotton without a cover crop (CwoC-D), and (4) dryland cotton with a winter wheat cover crop (CwC-D) at the Texas A&amp;M AgriLife Research Station at Chillicothe from 2011 to 2015. The average percent error (PE) between the CSM-CROPGRO-Cotton simulated and measured seed cotton yield was -10.1% and -1.0% during the calibration and evaluation periods, respectively, and the percent root mean square error (%RMSE) was 11.9% during calibration and 27.6% during evaluation. For simulation of aboveground biomass by the CSM-CERES-Wheat model, the PE and %RMSE were 8.9% and 9.1%, respectively, during calibration and -0.9% and 21.8%, respectively, during evaluation. Results from the long-term (2001-2015) simulations indicated that there was no substantial reduction in average seed cotton yield and soil water due to growing winter wheat as a cover crop.

Published: December 2017

Abstract. A woodchip-based gas-phase biofilter is capable of mitigating livestock airborne ammonia efficiently with low cost. Control of the moisture content (MC) of biofilter media is critical for ammonia mitigation and limiting nitrous oxide generation. It is important to monitor the real-time biofilter MC to maintain biofilter performance. The objectives of this study were to further develop and evaluate impedance-based MC measurement and to improve methodologies to monitor the MC of gas-phase biofilters. A sensor consisting of a sensing unit (three perforated parallel plates) and a circuit generating DC voltage output was used to measure MC. The sensor readings changed significantly with stepwise MC increases, particle size distribution, and nitrogen (ammonia-nitrogen, nitrate-nitrogen) concentrations in biofilter media. A mathematical model was developed for the relationship between the sensor reading and MC. A statistical model was established to predict the MC in biofilter media based on the sensor reading, ammonia-nitrogen concentration, and nitrate-nitrogen concentration. Keywords: Gas-phase biofilter, Impedance, Moisture sensor, Nitrogen compounds, Particle size distribution.

Published: December 2017

Abstract. AquaCrop is a crop simulation model developed by the FAO aimed at assessing the yield response to water supply. Once the model is calibrated and validated, it is a useful tool to simulate crop yields under different management options or climatic and soil conditions. Until now, AquaCrop has not been parameterized for dry beans ( L.), and thus our objective was to calibrate and validate the model for this crop using experiments performed 40 years ago at Davis, California. A set of parameters derived from the calibration with one irrigation experiment was used to validate the model using five experiments carried out in 1977 and 1978 that had treatments vastly differing in irrigation depth and frequency. Yield predictions over a wide range of values (&lt;1 to 3.5 t ha-1) were very good, with RMSE of 0.16 t ha-1 and Willmott’s d of 0.978. Seasonal ET was also accurately predicted by the model (RMSE = 40 mm, d = 0.930), as also evidenced by comparing the lysimeter measured ET of 489 mm against the lysimeter simulated ET of 501 mm. Canopy cover and the time course of biomass were adequately simulated as well. Even though total soil water extraction was well simulated, the simulated soil water distribution with depth differed from measured values in the dryland treatment. We conclude that AquaCrop can now be used for the simulation of dry beans in different environments, and we emphasize the value of carefully conducted field experiments for the validation of crop simulation models.

The surgical personality: does it exist?
Authors: Whitaker Matthew 
Published: December 2017

Introduction This study aims to answer the question of whether surgeons have different personalities to non-surgeons. Methods Members of the Royal College of Surgeons of England were sent an email survey containing 50 standard questions from the Five Factor personality assessment, which scores each respondent in five key personality traits (conscientiousness, agreeableness, neuroticism, openness, extroversion). Results were analysed and compared with a population-level data set from a survey conducted by the BBC. Results Five hundred and ninety-nine surgeons completed the survey. Analysis showed that surgeons scored significantly higher for conscientiousness, agreeableness, openness and neuroticism than non-surgeons (P < 0.05). Further analysis showed that female surgeons scored higher in openness and extroversion relative to the population average and that surgeons become more prone to neuroticism than non-surgeons as they age. Conclusions The results support the notion of a surgical personality, as well as indicating that female surgeons have significantly different personality profiles from male surgeons, and that age affects surgeons’ personalities in different ways to non-surgeons.

Reordering Nature: Power Politics in the Mughal Shikargah
Authors: Parpia Shaha 
Published: December 2017

Abstract
The Mughal shikargah (hunting ground) defies conventional spatial and functional definitions. Although fragmentary, references to the imperial shikargah in Indo- Mughal literature, memoirs, biographies, gazetteers, and documents suggest that the typology of the shikargah cannot be reduced simply to one form of natural terrain; nor was hunting game its sole purpose. The shikargah was conceptualized to accommodate multifarious functions. Whether areas of wilderness or dedicated preserves, the spaces used for hunting were transformed into public arenas in which the emperors could enact the hunt. In addition, other alterations to the natural environment enabled the occurrence of courtly activities. As the stage for imperial ceremonials and for the meting out of justice, or as sites of encampment and halting during royal inspection tours, the shikargah was inextricably linked to the administration and bureaucracy of the Mughal Empire. The hunt was also a pretext to mobilize armies for reconnaissance and intimidation of restive provinces, during which the shikargah became a venue for military training and armed intervention. Using the framework of the hunt to interpret natural landscapes, this article aims to examine the physical and political processes of modification underlying the Mughal shikargah, those that carried with them semiotics of political power and control.

The article presents the results of the study of the dependence of the flavonoid content of the herb Hypericum perforatum L., from growth conditions of cenopopulations in various ecological, cenotic conditions of the Republic of Tatarstan. Plant biocenosis were considered – meadows, Border of broadleaf and pine forest or artificial planting of pine. A qualitative and quantitative analysis of flavonoids in the herb of Hypericum perforatum was carried out by high-performance liquid chromatography. In studying water-alcohol extracts of H. perforatum L. flavonoids – rutin, quercetin, bisapigenin were identified by HPLC analysis. It is shown that the ecological, cenotic conditions of growth of Hypericum perforatum affect the quantitative content of phenolic compounds. It has been established that in investigated cenopopulations in the territory of the Republic of Tatarstan, rutin is the dominant flavonoid in medicinal plant raw materials. Maximum amount of this compound detected in the samples of Hypericum perforatum confined to the pine biocenosis of Tukaevsky and Drozhzhanovsky districts under significant quantity level of quercetin. In all variants of the experiment, bisapiginin was detected in small amounts. Plants of Hypericum perforatum, grow in different plant biocenosis differed in the various contents of the compounds of the phenolic complex, which is probably due to the ecological, cenotic and climatic conditions of growth.

Common sorrel (Rumex acetosa L.), Polygonaceae family, two-year herbaceous plant, contains a complex of biologically active compounds, based on phenolic compounds (flavonoids, coumarins, anthracene derivatives, tannins). Since ancient times it has been used in folk medicine as an anti-inflammatory, hemostatic, astringent. The purpose of this work is to study the composition of phenolic compounds of the aerial part of common sorrel, which grows on the territory of the Altai Territory. To achieve this goal, it is necessary to solve the following tasks: performe of qualitative reactions on phenolic compounds different groups, separation and identification of phenolic compounds by high-performance liquid chromatography.The results of qualitative reactions allow to suggest the presence of flavonoids flavone and flavanol groups, anthracene derivatives of the chrysacin group, coumarins and condensed tannins in aerial part.High-performance liquid chromatography of common sorrel aerial part ethanol extract (extrctant – 70% ethanol) were used to identify the flavonoids of the flavanol group: kaempferol and quercetin derivatives, anthracene derivatives of the chrysacin group.The studies are aimed at studying the possibility of using the aeral part of common sorrel in medicine. Based on the conducted studies, the development of normative documentation for medicinal plant raw materials is being carried out.
