PurposeHospital solid waste may cause serious health hazards and impair the quality of life of the community through transmission of diseases and injury if not properly managed. Therefore, the purpose of this paper is to examine solid waste management practice (SWMP) in Obafemi Awolowo University Teaching Hospital Complex.Design/methodology/approachPrimary data were collected for this study through interview and questionnaire administration. Systematic sampling technique was used to select 60 students, 13 staffs, 43 cleaners, 8 contractors, and a management staff for questionnaire administration. Data obtained were analyzed using frequency distribution, pictorial analysis, and factor analysis.FindingsFindings established that solid wastes components generated in the hospital were not segregated in line with the directive of the World Health Organization. The study further established that the factors influencing SWMP accounted for 79.9 percent variance in the following proportion: available storage and collection facilities (30.94 percent), number of patients’ factors (17.86 percent), transportation factor (15.39 percent), human and material resource factors (8.33 percent), and disposal (7.36 percent).Originality/valueThe study therefore concludes that the effectiveness of SWMPs depends on the facilities and equipment, human resources capacity, and frequency of waste collection and disposal.

Authors: Chauhan Ankur , Singh Amol 
Published: February 2018

Purpose
The purpose of this paper is to explore the drivers of healthcare waste management from literature review and field survey and model these drivers for understanding the inter-relationships among the drivers to enhance healthcare waste management in the Indian context.

Design/methodology/approach
In view of the need of the study, the interpretive structural modelling (ISM) method has been applied to model the drivers. The ISM method helps in depicting the relationships among the drivers and filtration of drivers on the basis of their driving and dependence power.

Findings
The findings of the study reveal that the type of a healthcare facility and its management structure, size of a healthcare facility, human resource management of a healthcare facility, healthcare facility’s management monitoring and control, and the effective re-enforcement of government regulation and policy implementation in a healthcare facility play a vital role in the enhancement of HCWM.

Research limitations/implications
The application of the findings of this study would enhance the hospital’s waste management by ultimately leading to a good ambience and satisfied patients and personnels. Additionally, the study would aid in the policy formulation by government and decision making of medical facilities, thereby strengthening HCWM scenario in the country.

Practical implications
The drivers filtered in this study would be useful for ranking the hospitals’ healthcare waste management in a region/country. This ranking may play a vital role in earmarking the hospitals which are managing their healthcare waste according to the guidelines of Central Pollution Control Board (CPCB) and Ministry of Environment and Forest (MoEF) of a country. With the help of this study, the problem of inadequate human resource can be effectively addressed for CPCB and MoEF, in India.

Originality/value
Healthcare waste management is a vital issue which needs attention from the management perspective in India. Therefore, an interpretive structural model, i.e. ISM digraph, has been developed which would help in the filtration of drivers and attaining the better healthcare waste management in an economically and timely manner.

Performance review: online research guides for theater students
Authors: Furay Julia 
Published: February 2018

Purpose
This study aims to assess current academic library services to theater students through an examination of online research guides.

Design/methodology/approach
This study uses a representative sample of 100 universities that offer theater degrees; the library website at each of these institutions is examined for the existence of a theater research guide. Each research guide was analyzed in depth.

Findings
The vast majority of the universities in the sample did create research guides for theater students, though the contents of these guides varied greatly. The study highlights findings including popular databases and journals for theater students, as well as media resources and common subjects for subsections or course guides.

Research limitations/implications
This study only examined a sample of 100 institutions; many theater research guides were not examined for this study. Additionally, analysis of online content is a time-specific endeavor: a guide may look significantly different from one month to the next, though the recommendations in this article might prove useful even if the sites at these institutions have since been updated.

Practical implications
Through an examination of a great number of guides, a few practical suggestions emerge for librarians looking to create theater research guides, such as highlighting playscripts and other print materials and including hyperlocal information (such as university production history).

Originality/value
Though several studies have been performed on research guides in various disciplines, this article is the first on those to theater students.
Tapping government sources for course assignments
Authors: Dubicki Eleonora , Bucks Susan 
Published: February 2018

Purpose
This study aims to explore how government sources provide authoritative data that students can utilize to complete academic course assignments. The study measures student use of government materials and suggests that librarians incorporate government resources into information literacy instruction.

Design/methodology/approach
A five-question paper-and-pencil feedback survey was developed by the researchers and completed at the end of the semester by students in several sections of health and social work classes. The survey measured the level and ease of usage of government information/websites. Students also identified US and state government sources they used to complete their assignments.

Findings
Government information can become a critical resource for a life-long learning experience when introduced to students early in their academic careers in freshmen seminars or introductory courses. Government information can be utilized as an authoritative source for research assignments. In addition, students anticipate using government information as they enter their professional careers. Librarians and faculty can work in tandem to build students’ government information literacy skills.

Research limitations/implications
While this study focuses on health and social work, use of online government information by other disciplines should be further investigated.

Social implications
The findings will be useful for integrating government information into information literacy sessions. Improved familiarity of government information creates more informed professionals and citizens.

Originality/value
This study adds to the body of literature on government literacy. Recommendations are offered on familiarizing users with government sources and improving access to documents via multiple library access points.
Investigating the performance of powder mixed electric discharge machining of Nimonic 75 by using different tool materials
Authors: S. Ramesh , M.P. Jenarthanan 
Published: February 2018

Purpose
This study aims to focus on experimenting the performance of aluminum (Al) powder mixed electric discharge machining (PMEDM) of two different materials viz plastic mould die steel (AISI P20) and nickel-based super alloy (Nimonic 75). This experimental study also focuses on using three different tool materials such as copper, brass and tungsten to analyze their influence on the process output. These materials find many uses in industrial as well as aerospace applications. The performance measures considered in this work are material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR).

Design/methodology/approach
The experimental design used in this work is based on Taguchi’s L18 orthogonal array. Besides considering work and tool material as one of the process variables, other process variables are peak current (Ip), pulse on time (Ton) and concentration of powder (Cp). The analysis of variance (ANOVA) is performed on the experimental data to determine the significant variables that influence the output.

Findings
It is found that copper produced maximum MRR and brass tool exhibited higher TWR. However, the surface finish of the machined work piece was very much improved by using the brass tool. Though the performance of tungsten tool lies between the above two tool materials, it showed very little wear during EDM with or without the addition of Al powder.

Originality/value
The experimental investigation of PMEDM of nickel-based super alloy (Nimonic 75) has not been attempted before. Besides that, the study on the influence of tungsten tool on the performance of EDM is also very limited.
A sliding mode controller-based STATCOM for voltage profile improvement of micro-grids
Authors: Pati Swagat , Mohanty Kanungo Barada , Kar Sanjeeb Kumar 
Published: February 2018

Purpose
The purpose of this paper is to evaluate the suitability and robustness of sliding mode controller (SMC) for maintaining flat voltage profile at the load bus of two different micro-grid systems using STATCOM.

Design/methodology/approach
Two micro-grid systems are dynamically modelled and simulated using MATLAB/Simulink. The first micro-grid has a single diesel engine-driven synchronous generator. The second micro-grid has one diesel engine-driven synchronous generator and a doubly fed induction generator-based wind energy conversion system. The STATCOM is connected to the load bus in both the micro-grids. SMC is used for the control of STATCOM for voltage profile improvement of micro-grid. The performance of SMC-based STATCOM is analysed and compared with the performance of conventional PI controller-based STATCOM.

Findings
The SMCs are more suited for STATCOM control as these are more immune to load disturbances even with the presence of wind energy generators. The voltage deviations and the steady state errors in voltage are less with SMC. Although SMC introduces a bit of steady state error in the dc link voltage of the STATCOM, it is much less than the settling limit of 2 per cent, which is quite acceptable. SMC proves to be better than conventional PI controllers in both the proposed models of micro-grid.

Originality/value
Design of a robust first-order SMC for a STATCOM is used for voltage profile improvement in two different micro-grid systems.
Two dimensions define the variation of fine root traits across plant communities under the joint influence of ecological succession and annual mowing

Published: February 2018

Abstract

Quantifying the variation in community‐level fine root (<2 mm) traits along ecological gradients or in response to disturbances is essential to unravel the mechanisms of plant community assembly, but available surveys are scarce. Whether fine root traits covary along a one‐dimensional economic spectrum, as previously shown for leaves, is highly debated.

We measured six fine root traits at the community level along a 69‐year succession, with or without annual mowing, offering a unique design of two nested disturbances. We examined whether (1) there is variation and covariation in community‐level fine root traits along the succession and in response to mowing and (2) morphological root traits mirrored analogous leaf traits (using previously acquired data).

Early‐successional communities were herbaceous‐dominated (48 ± 6% in <10‐year‐old plots) and possessed fine roots with high specific root length (SRL), low root dry matter content (RDMC) and low root carbon concentration (RCC), while later successional communities were dominated by woody species (56 ± 9% in >40‐year‐old plots) and possessed opposite trait values. Root nitrogen concentration (RNC) did not vary across communities along the succession. The trait values at community level were not affected by mowing, except for a reduction in root mass density.

We found covariation of fine root traits across communities along two dimensions: the first dimension (60% of total variation) represented changes in root foraging capacity (related to SRL) and resource conservation (related to RDMC, RCC, mean root diameter), whereas the second dimension (17%–20% of the variation) represented variations in RNC, potentially related to root respiration and metabolism.

Specific root length and specific leaf area were correlated regardless of the mowing regime, but there was no analogous relationship between leaf dry matter content and RDMC in mown communities, showing a decoupling in the investment in tissue density above‐ and below‐ground.

Synthesis. Our study demonstrates coordinated variations of community‐level fine root traits along a succession gradient and provides evidence that fine root traits covaried along two dimensions, regardless of mowing regime. The relationship between leaf dry matter content and root dry matter content observed in unmown communities was modified by mowing, reflecting an uncoupled response to mowing.
Fluid Evolution and Ore‐forming Processes of the Jiama Cu Deposit, Tibet: Evidence from Fluid Inclusions
Authors: YAO Xiaofeng , LIU Jiajun , TANG Juxing , ZHENG Wenbao , ZHANG Zhi 
Published: February 2018

AbstractThe Jiama deposit is a large copper deposit in Tibet. Mineralization occurs in three different host rocks: skarn, hornfels and porphyry. A detailed fluid inclusion study was conducted for veins in the different host rocks to investigate the relationship between fluid evolution and ore‐forming processes. Based on examination of cores from 36 drill holes, three types of veins (A, B and D) were identified in the porphyries, four types (I, II, III and IV) in the skarn, and three (a, b and c) in the hornfels. The crosscutting relationships of the veins and that of the host rocks suggest two hydrothermal stages, one early and one late stage. Fluid inclusions indicate that the Jiama hydrothermal fluid system underwent at least two episodes of fluid boiling. The first boiling event occurred during the early hydrothermal stage, as recorded by fluid inclusions hosted in type A veins in the porphyries, type a veins in the hornfels, and wollastonite in the skarns. This fluid boiling event was associated with relatively weak mineralization. The second boiling event occurred in the late hydrothermal stage, as determined from fluid inclusions hosted in type B and D veins in the porphyries, type I to IV veins in the skarns, and type b and c veins in the hornfels. This late boiling event, together with mixing with meteoric water, was responsible for more than 90% of the metal accumulation in the deposit. The first boiling only occurred in the central part of the deposit and the second boiling event took place across an entire interlayered structural zone between hornfels and marble. A spatial zoning of ore‐elements is evident, and appears to be related to different migration pathways and precipitation temperatures of Cu, Mo, Pb, Zn, Au and Ag.
Zircon U‐Pb age, Trace Element, and Hf Isotopic Compositions of Nordmarkite in the Lizhuang Rare Earth Element Deposit in the Western Margin of the Yangtze Block

Published: February 2018

AbstractThe Mianning–Dechang (MD) rare earth element (REE) belt, located in the northern Kangdian axis (KDA) in the western margin of the Yangtze platform, is one of the most economically significant REE mineral belts in China. REE mineralization is associated with Himalayan carbonatite–alkaline complexes. The Lizhuang nordmarkite occurred in the northern part of the MD REE belt. The majority of zircons from the Lizhuang nordmarkite are characterized by pronounced positive Ce yet slightly negative Eu anomalies and high U/Yb. Moreover, all zircons have stable Hf isotopic compositions with initial 176Hf/177Hf ratios ranging from 0.282739 to 0.282808 and an average value of 0.282773. The negative Lu/Hf and positive εHf(t) range from −0.98 to −0.94 (average value of −0.96) and from −0.56 to 1.89 (the majority is positive, with an average of 0.66), respectively. These characteristics indicate that the rock is derived from an enriched mantle and subducted material. LA‐ICP‐MS analysis of the zircons from the intrusion yields a weighted mean 206Pb/238U age of 28.57±0.61Ma. During this period, the tectonic activity in the KDA is not plate subduction but an intraplate tectonic exhibiting fold–thrust and strike–slip behaviors in the western marginal zone of the Yangtze platform (WMYB). We suggest the possibility of an existing eastward old slab subduction under WMYB combined with a regional tectonic evolution. The Lizhuang nordmarkite may be derived from an enriched mantle beneath the western part of the Yangtze craton, which originated from the remelting of the Tethys subducting slab, because of the Himalayan strike–slip that formed a special type of REE deposit called strike–slip‐type REE deposits.
Pore Types and Quantitative Evaluation of Pore Volumes in the Longmaxi Formation Shale of Southeast Chongqing, China
Authors: CHEN Fangwen , LU Shuangfang , DING Xue 
Published: February 2018

AbstractThe common microscale to nanoscale pore types were introduced and divided into organic and inorganic pores to estimate their contributions to porosity in the Lower Silurian Longmaxi Formation shale of southeast Chongqing. Following the material balance principle, the organic porosity values, which changed with formation subsidence and thermal evolution, were calculated using chemical kinetics methods and corrected via the organic porosity correction coefficient, which was obtained from field emission scanning electron microscopy. Grain density values were determined using the contents and true densities of compositions in the shale samples. The total porosity was calculated based on the grain and bulk densities. The inorganic porosity was determined from the difference between the total porosity and organic porosity at the same depth. The results show that inorganic pores mainly contain microfractures, microchannels, clay intergranular pores, intercrystalline pores and intracrystalline pores in the Lower Silurian Longmaxi Formation shale of southeast Chongqing. Organic pores mainly include organopore and fossil pore. The total porosity, organic porosity and inorganic porosity of organic‐rich shale samples can be quantitatively evaluated using this method. The total porosity, organic porosity and inorganic porosity values of the Longmaxi Formation shale samples from the well Py1 in southeast Chongqing lie in 2.75%–6.14%, 0.08%–2.52% and 1.41%–4.92% with average values of 4.34%, 0.95% and 3.39%, respectively. The contributions of the inorganic pores to the total porosity are significantly greater than those of the organic pores.
Longitudinal Associations Between Alcohol‐Related Cognitions and Use in African American and European American Adolescent Girls

Published: February 2018

BackgroundAfrican American (AA) girls initiate alcohol use later and drink less than European American (EA) girls, potentially reflecting differences in the development of drinking behaviors. This study examined alcohol‐related cognitions: expectancies, attitudes, and intention to drink, as possible sources of variation by race in alcohol use. The aim of this study was to characterize the nature and degree of association between cognitions and use over time and by race in EA and AA girls.MethodsData were drawn from the longitudinal Pittsburgh Girls Study (N = 2,450), an urban population‐based sample of girls and their caregivers recruited when girls were between ages 5 and 8, and assessed annually through adolescence. Cross‐lagged panel models were conducted separately by race (56.2% AA, 43.8% EA) to identify patterns of association between alcohol use and cognitions from ages 12 to 17 in 2,173 girls.ResultsEndorsement of cognitions and use was higher overall in EA than AA girls but the magnitude of cross‐lagged path coefficients did not differ significantly by race. In both groups, bidirectional effects emerged between intentions and use, and alcohol use largely predicted cognitions across ages. However, intention to drink was the only alcohol‐related cognition that consistently predicted subsequent use (odds ratios ranged from 1.55 to 2.71).ConclusionsAlthough rates of alcohol use and endorsement of cognitions were greater in EA than AA girls, the anticipated racial differences in longitudinal associations between cognitions and use did not emerge, indicating that variation in associations between use and cognitions does not account for the lower prevalence of alcohol use in AA compared with EA girls. Furthermore, our finding that intention to drink is a consistent, robust predictor of subsequent alcohol use suggests the need to investigate potentially modifiable factors that influence intention to drink across racial groups.
Does well‐being impact individuals’ risky decisions and susceptibility to cognitive bias?
Authors: Moulang Carly , Strydom Maria 
Published: February 2018

AbstractThis article explores the relation between individual well‐being, risky decision‐making, susceptibility to cognitive biases and investor beliefs about investing. A survey of one hundred and two individuals revealed that those with higher satisfaction with life are more prone to taking risks. In a loss frame, participants who were most likely to take a gamble had higher levels of psychological, social and overall well‐being. Lower levels of satisfaction with life were found to impact the susceptibility of the reflection effect cognitive bias. In addition to this, well‐being was found to be associated with investment beliefs, particularly those concerning diversification, the need to be alert and active, and the risk/return trade‐off.
