An enhanced pose tracking method using progressive scan matching
Authors: Yuan Rupeng , Zhang Fuhai , Qu Jiadi , Li Guozhi , Fu Yili 
Published: May 2019

Purpose
The purpose of this paper is to propose an enhanced pose tracking method using progressive scan matching, focusing on accuracy, time efficiency and robustness.

Design/methodology/approach
The general purpose of localization algorithms is to dynamically track a robot instead of globally locating one. In this paper, progressive scan matching is used to promote the performance of pose tracking. Rotational and translational samples are separately generated to accelerate the calculation and to increase the accuracy. Progressive iteration of sample generation can ensure localization to achieve a specific precision. The direction of localization uncertainty is taken into consideration to increase robustness. Nonlinear optimization is adopted to achieve a more precise result.

Findings
The proposed method was implemented on a self-made mobile robot. Two experiments were conducted to test the accuracy and time efficiency of the method. The comparison with the basic Monte Carlo localization shows the advantages of the method. Another two experiments were conducted to test the robustness of the method. The result shows that the method can relocate a robot from an inaccurate place if the offset is moderate.

Originality/value
An enhanced pose tracking method is proposed to promote the performance by separately processing rotational and translational samples, progressively iterating the sample generation, taking the direction of localization uncertainty into consideration and adopting nonlinear optimization. The proposed method enables a robot to accurately and quickly locate itself in the environment with robustness.
Evaluating library service quality of University of Kashmir: a LibQUAL+ survey
Authors: Kumar Anil , Mahajan Preeti 
Published: May 2019

Purpose
The purpose of this paper is to evaluate the library service quality (LSQ) of University of Kashmir from the users’ perspectives based on the LibQUAL+ model approach.

Design/methodology/approach
The survey used the LibQUAL+ model to evaluate service quality (SQ) of Allama Iqbal Library (AIL), University of Kashmir, Srinagar (India). The data were collected from library users by administering the LibQUAL+ questionnaire in a printed format.

Findings
It has been revealed that AIL has succeeded in satisfying the minimum expectations of its users but could not meet the customers’ desired expectations that make them delighted. Library as Place (LP) and Information Control (IC) are the most satisfied dimensions of SQ of AIL, whereas Affect of Service (AS) is the least satisfied dimension. LP is the most desired dimension amongst LibQUAL+ dimensions. All LibQUAL+ items were found to be lying inside the zone of tolerance (ZoT). Further, “Library is secure and peaceful place for study, learning and research” (LP-21) was found as most important service item as per users’ desired expectations, while “Library staff shows dependability in handling users’ service problems” (AS-9) is marked as the least desired item.

Originality/value
Only a few studies have been carried out to evaluate the SQ of Indian university libraries as far as the LibQUAL+ model is concerned. Therefore, the findings of present survey will help to understand how far library has reached in satisfying users’ expectations as well as the areas or dimensions where it needs to improve.
Revision of an academic library user experience survey
Authors: Aksu Dunya Beyza , De Groote Sandra 
Published: May 2019

Purpose
The purpose of this paper is to explain how an academic library’s Student Experience Survey was revised and improved based on available research on survey design methodology and piloting efforts. Thus, it aims to contribute existing literature on library assessment and survey methodology by addressing issues of planning and coordinating assessment. The paper also provides a guideline on the survey revision process for existing instruments.

Design/methodology/approach
The library assessment coordinator collaborated with Assessment Coordinator Advisory Committee (AC2) to revise and improve the survey. The revision process started with adding suggested items and constructing new items based on library assessment planning survey administered to library faculty previously. Regular monthly meetings were held with the committee to facilitate the revision process. Multiple facets of the survey implementation were revised including wording, content, order and format of the items, response scales and survey distribution. Each facet was addressed based on available research on survey methodology and cross-checked with the committee members.

Findings
The revised 2018 University of Illinois at Chicago (UIC) Libraries Student Experience Survey consists of a total of nine items with response matrices, single choice response format and open-ended response format to measure students’ satisfaction, need and their use of the various library resources and services. The changes made to the survey are grouped into three categories: wording and content, response categories and scaling and design, font and layout. The revision process of the UIC Libraries Student Experience Survey can serve as an example for academic or other types of libraries that wish to track and report their impact regularly.

Originality/value
The UIC Libraries Student Experience Survey provides evidence that careful revision and piloting as well as obtaining relevant stakeholder buy-in to the process lead to build effective survey tools.
Specialist foragers in forest bee communities are small, social or emerge early
Authors: Smith Colleen , Weinman Lucia , Gibbs Jason , Winfree Rachael 
Published: May 2019

Abstract

Individual pollinators that specialize on one plant species within a foraging bout transfer more conspecific and less heterospecific pollen, positively affecting plant reproduction. However, we know much less about pollinator specialization at the scale of a foraging bout compared to specialization by pollinator species.

In this study, we measured the diversity of pollen carried by individual bees foraging in forest plant communities in the mid‐Atlantic United States.

We found that individuals frequently carried low‐diversity pollen loads, suggesting that specialization at the scale of the foraging bout is common. Individuals of solitary bee species carried higher diversity pollen loads than did individuals of social bee species; the latter have been better studied with respect to foraging bout specialization, but account for a small minority of the world’s bee species. Bee body size was positively correlated with pollen load diversity, and individuals of polylectic (but not oligolectic) species carried increasingly diverse pollen loads as the season progressed, likely reflecting an increase in the diversity of flowers in bloom. Furthermore, the seasonal increase in pollen load diversity was stronger for bees visiting trees and shrubs than for bees visiting herbaceous plants.

Overall, our results showed that both plant and pollinator species’ traits as well as community‐level patterns of flowering phenology are likely to be important determinants of individual‐level interactions in plant–pollinator communities.
Geochemical Assessment and Lateral Reservoir Continuity of Asmari Reservoir Oils in the Cheshmeh‐Khush Oilfield, SW Iran

Published: May 2019

AbstractA total of 6 oil samples were systematically selected from six Asmari Reservoir wells in the Cheshmeh‐Khush Oilfield for geochemical evaluation of the hydrocarbon system, based on reservoir geochemistry and oil fingerprints. An investigation of the distribution patterns of normal alkanes and tricyclic and tetracyclic terpanes along with characteristic biomarkers of the depositional environment and sedimentary facies, indicated that the source rock of the studied hydrocarbons was deposited in a reducing aquatic environment with a low input of terrigenous material and predominantly carbonate lithology derived from organic algal matter. The studied oil samples exhibited moderate maturity, as was further confirmed by the parameters extracted from the light hydrocarbons. Statistical clustering based on different biomarker parameters indicated the presence of two oil families. Additionally, the application of branched and cyclic compounds in the light hydrocarbons (C5–C11) to evaluate lateral continuity of the Asmari reservoir further supported the presence of the two oil families. Other evidence proved the presence of a NE–SW trending fault separating wells X5 and X6 from the other wells in the field. In other wells across the field, good lateral reservoir continuity was observed, despite the presence of faults on the northern and southern plunges of the structure.
Geochemical Aspects of Hypogene Hydrothermal Alteration Zones in the Chol‐qeshlaghi Area, NW Iran: Constrains on REEs
Authors: SIAHCHESHM Kamal , SHAHSAVANI BAMI Mohammad 
Published: May 2019

AbstractChol‐qeshlaghi altered area lies in the northwestern part of the post‐collisional Urumieh‐Dokhtar magmatic arc, NW Iran. Pervasive silicic, argillic, phyllic and propylitic altered zones appears to be intimately affiliated to the fluids derivative of upper Oligocene Khankandi granodiorite. This paper is dedicated to the identification of geochemical characteristics of hydrothermal alterations, focusing on the determination of the mass gains and losses of REEs, to gain significant insights regarding the chemical exchanges prevailed between the host rocks and hydrothermal fluids. The low pH and high activity of SO4‐2 ligands in silicic alteration fluids, resulting in depletion of entire REEs. Decreasing of LREEs appeared in argillic zone may attributed to reduce in adsorption ability of clay minerals in low pH; whereas HREEs enrichment in phyllic zone was inclined to put it down to the abundance of sericite (± Fe oxides). A significant reduction of Eu/Eu* ratio in silicic zone can be attributed to negligible sulfides and clay minerals as some effective agents in adsorption of released Eu+2. Factors such as changes in pH, the abundance of absorptive neomorph mineral phases, activity of ligands play an important role in controlling the distribution and concentration of REEs in Chol‐qeshlaghi alteration system.
Anisotropic Rock Poroelasticity Evolution in Ultra‐low Permeability Sandstones under Pore Pressure, Confining Pressure, and Temperature: Experiments with Biot's Coefficient
Authors: DU Shuheng 
Published: May 2019

AbstractThis study aimed to show anisotropic poroelasticity evolution in ultra‐low permeability reservoirs under pore pressure, confining pressure, and temperature. Several groups of experiments examining Biot's coefficient under different conditions were carried out. Results showed that Biot's coefficient decreased with increased pore pressure, and the variation trend is linear, but the decreasing rate is variable between materials. Biot's coefficient increased with increased confining pressure; the variation trend is linear, but the increasing rate varies by material as well. Generally, Biot's coefficient remains stable with increased temperature. Lithology, clay mineral content, particle arrangement, and pore arrangement showed impacts on Biot's coefficient. For strong hydrophilic clay minerals, expansion in water could result in a strong surface adsorption reaction, which could result in an increased fluid bulk modulus and higher Biot's coefficient. For skeleton minerals with strong lipophilicity, such as quartz and feldspar, increased oil saturation will also result in an adsorption reaction, leading to increased fluid bulk modulus and a higher Biot's coefficient. The study's conclusions provide evidence of poroelasticity evolution of ultra‐low permeability and help the enhancing oil recovery (EOR) process.

Published: May 2019

AbstractObjectivesThe emphasis on capturing patient‐reported outcomes (PRO) is increasing, but gout‐specific PRO are lacking. We evaluated the reliability and validity of the 24‐item Gout Impact Scale (GIS) of the Gout Assessment Questionnaire 2.0 (GAQ2.0) in a multi‐ethnic Asian population.MethodsParticipants with gout in an academic medical center in Singapore completed the GIS which comprises five scales. Confirmatory factor analyses (CFA) were performed. Known‐groups validity, divergent validity and internal consistency were evaluated.ResultsWe analyzed data of 267 participants (mean [SD] age 52.2 [16.08] years, 92.1% men and 76.0% Chinese). CFA based on the original GIS factor structure had good model fit based on Tucker‐Lewis Index (TLI) of 0.946 but not when based on Root Mean Square Error Of Approximation (RMSEA), which was 0.123 (90% CI: 0.116‐0.130). Internal consistency of GIS exceeded 0.7 in all except one scale, consistent with previous studies. Hypotheses related to known‐groups validity were largely supported. Scores were significantly higher (ie greater impact) for participants reporting at least some problem on the EQ‐5D‐3L anxiety/ depression item across all GIS scales. Correlations between RAND‐36 Physical Functioning (PF) scale and all five scales in the GIS were poor (Spearman rank correlation coefficients: −0.2355 to 0.0426), implying that GIS does not measure impact of gout on physical health.ConclusionThe GIS is valid and reliable for assessing gout‐specific psychosocial functioning in a multi‐ethnic Asian population.

ABSTRACTAimsTo examine whether norms towards nicotine vaping product (NVP) use varied between Australia, Canada, England and the United States and by socio‐demographics, smoking and NVP status.DesignCross‐sectional data from the 2016 ITC Four Country Smoking and Vaping Survey.SettingFour countries with distinct regulatory policies relating to the sale and advertising of NVPs: Australia (most restrictive), Canada (restrictive), England and the United States (least restrictive).ParticipantsA total of 10900 adult (age 18+) current smokers, former smokers, or at least weekly NVP users. Respondents were from Australia (n = 1366), Canada (n = 3309), England (n = 3835) and the United States (n = 2390).MeasurementsQuestions permitted the categorization of respondents as current smokers, former smokers, NVP users and socio‐demographic categories (sex, age, country, ethnicity, income and education). Further questions were asked regarding the frequency of exposure to NVPs in public, whether they had a partner or close friends who vaped and whether they believed society or those considered important to them approved of NVPs.FindingsAdjusting for relevant covariates, compared with Australian respondents, those in England, Canada and the United States were more likely to report frequent exposure to NVPs in public (83.1%, 57.3% and 48.3%, respectively, compared to 19.8% in Australia; P < 0.0001), having a partner who vaped (13.8%, 7.1% and 7.7%, respectively, compared to 2.1% in Australia; P < 0.0001) and having close friend(s) who vaped (31.7%, 25.3%, 20.9%, respectively, compared to 10.0% in Australia; P < 0.0001). Compared with Australian respondents, respondents from England were more likely to report that society (27.6% compared to 12.3% in Australia; P < 0.0001) and people important to them approved of NVP use (28.9% compared to 14.3% in Australia; P < 0.0001).ConclusionsNorms towards nicotine vaping product (NVP) use appear to vary among countries with different regulatory contexts regarding sales and advertising.
More than just numbers! Perceptions of remote area nurse staffing in Northern Territory Government health clinics
Authors: Dunbar Terry , Bourke Lisa , Murakami‐Gold Lorna 
Published: May 2019

AbstractObjectiveThe need for more Remote Area Nurses in the Northern Territory is clear. This paper investigates the perspectives of Remote Area Nurse workforce issues among multiple stakeholders. The aim is to identify how Remote Area Nurse staffing issues are perceived by clinic managers, Remote Area Nurses themselves, Aboriginal colleagues and community members in seven remote communities in the Northern Territory.DesignThis is a qualitative study that uses interviews and focus groups to identify key messages of local stakeholders about Remote Area Nurse workforce issues. A content analysis was used for data analysis.SettingSeven diverse remote Aboriginal communities in the Northern Territory with government‐run health clinics were visited.ParticipantsNon‐random sampling techniques were used to target staff at the clinics at the time of field work. Staff and community members, who agreed to participate, were interviewed either individually or in groups. Interviews were conducted with 5 Managers, 29 Remote Area Nurses, 12 Aboriginal staff (some clinics did not have Aboriginal staff) and 56 community residents. Twelve focus groups were conducted with community members.ResultsContent analysis revealed that participants thought having the “right” nurse was more important than having more nurses. Participants highlighted the need for Remote Area Nurses to have advanced clinical and cultural skills. While managers and, to a lesser extent, Remote Area Nurses prioritised clinical skills, Aboriginal staff and community residents prioritised cultural skills.ConclusionsParticipants identified the importance of clinical and cultural skills and reiterated that getting the “right” Remote Area Nurse was more important than simply recruiting more nurses. Thus, retention strategies need to be more targeted and cultural skills prioritised in recruitment.
UK Unions, Collective Action and the Cost Disease
Authors: Willman Paul , Bryson Alex , Forth John 
Published: May 2019

AbstractThis article looks at the financial resources of trade unions in the UK. The core argument is that trade unions are subject to ‘cost disease’ pressures such that costs rise over the long term above the general level of inflation. They have this property because of the difficulty in solving first‐ and second‐order collective action problems. First‐order problems refer to the problems of initiating collective action and second‐order problems refer to the management of collective action organizations. Both UK aggregate and case‐study data — from one of the largest UK unions, Unite — are presented to illustrate the cost disease problem and to suggest options for its management. In conclusion, the wider implications of ‘cost disease’ pressures for unions are assessed.

ObjectivesTo test whether using disease prognosis can inform a rational approach to active surveillance (AS) for early prostate cancer.Patients and methodsWe previously developed the Cambridge Prognostics Groups (CPG) classification, a five‐tiered model that uses prostate‐specific antigen (PSA), Grade Group and Stage to predict cancer survival outcomes. We applied the CPG model to a UK and a Swedish prostate cancer cohort to test differences in prostate cancer mortality (PCM) in men managed conservatively or by upfront treatment in CPG2 and 3 (which subdivides the intermediate‐risk classification) vs CPG1 (low‐risk). We then applied the CPG model to a contemporary UK AS cohort, which was optimally characterised at baseline for disease burden, to identify predictors of true prognostic progression. Results were re‐tested in an external AS cohort from Spain.ResultsIn a UK cohort (n = 3659) the 10‐year PCM was 2.3% in CPG1, 1.5%/3.5% in treated/untreated CPG2, and 1.9%/8.6% in treated/untreated CPG3. In the Swedish cohort (n = 27 942) the10‐year PCM was 1.0% in CPG1, 2.2%/2.7% in treated/untreated CPG2, and 6.1%/12.5% in treated/untreated CPG3. We then tested using progression to CPG3 as a hard endpoint in a modern AS cohort (n = 133). During follow‐up (median 3.5 years) only 6% (eight of 133) progressed to CPG3. Predictors of progression were a PSA density ≥0.15 ng/mL/mL and CPG2 at diagnosis. Progression occurred in 1%, 8% and 21% of men with neither factor, only one, or both, respectively. In an independent Spanish AS cohort (n = 143) the corresponding rates were 3%, 10% and 14%, respectively.ConclusionUsing disease prognosis allows a rational approach to inclusion criteria, discontinuation triggers and risk‐stratified management in AS.
Does peer group size influence social preferences and risk taking?
Authors: Roush Justin , Santore Rudy , Cotten Stephen J. 
Published: May 2019

AbstractThis paper examines whether the ex post relative payoffs of peers as well as the size of the peer group impact an agent's willingness to take risks. For example, persons in a flood plain may be less likely to purchase flood insurance if their neighbors also refrain from purchasing. We generalize the Fehr‐Schmidt (1999) model to allow the intensity of the social preferences to vary with the size of the peer group. Our experiment tests whether subjects are more or less likely to choose a lottery over a fixed payment when others have been assigned either the same lottery or the fixed payment. Using both between and within subject designs, we find risk‐taking behaviour is not responsive to the risks faced by others regardless of the size of peer group.
The Effects of Perceived Islamophobia on Group Identification and Acculturation Attitudes
Authors: Bastug Mehmet F. , Akca Davut 
Published: May 2019

AbstractThis study examines the effects of perceived Islamophobia on group identification and acculturation attitudes in a sample of Turkish Canadians. We tested the rejection‐identification model (RIM) and the rejection‐disidentification model (RDIM) to examine how perceived Islamophobia affects religious and national identification. The study also explores whether perceived Islamophobia, national identification, and religious identification have any impact on the acculturation attitudes of Turkish immigrants. All relationships were investigated using path analysis. The results suggest that perceived Islamophobia does not affect religious or national identification. Results also show that perceived Islamophobia positively predicts endorsement of marginalization as an acculturation strategy. National identification predicts higher levels of integration and assimilation and lower levels of separation. Those who report higher religious identification are more inclined to prefer separation.
