Authors: Qian Jin-yuan , Wu Zan , Zhang Qian-Kun , Jin Zhi-Jiang , Sunden Bengt Ake 
Published: August 2019

Purpose
The purpose of this paper is to study the effects of dimple geometries and arrangements on the heat transfer enhancement in a dimple jacketed heat exchanger.

Design/methodology/approach
For the purpose of this paper, with the experimental validated numerical model, this paper carries out numerical simulations of both single dimples with different geometries and the whole dimple jacketed heat exchanger with different dimple arrangements. For a single dimple, its secondary vortex flow, temperature differences and the pressure drop performance for different geometries are analyzed. For the whole dimple jacketed heat exchanger, the heat transfer and pressure drop performances are investigated by comparing the no dimple, triangular and rectangular dimple arrangements.

Findings
Results show that dimples can improve the heat transfer efficiency compared with conventional jacketed heat exchanger, and specific geometries and arrangement of dimples for better heat transfer performance are figured out.

Originality/value
This paper considers both dimple geometries and arrangements, which can be useful for further applications in specific integrated devices or similar applications.
Quality improvement in hospice settings: perceptions of leaders
Authors: Singh Jitendra , Sillerud Brandi , Omar Marah 
Published: August 2019

Purpose
The purpose of this paper is to explore and examine attitudes and perceptions of leaders on application of quality improvement (QI) strategies in a palliative and hospice care organization.

Design/methodology/approach
This study employed qualitative research methodology where leaders working in a hospice and palliative care organization were invited to participate in 45–60-min-long semi-structured interview. Interviews were recorded and transcribed verbatim. Qualitative content analysis was utilized to analyze the data collected during participant interviews.

Findings
Seven leaders participated in the interviews. Five themes were developed from data analysis: patient-centered care; continuous QI; leadership involvement and commitment; communication as a foundation for QI; and perceived barriers. Data analysis suggests that use of QI approach in palliative and hospice care enhances the quality of care provided for patients, and can help improve patient satisfaction.

Practical implications
Because there is a paucity of research on implementation of QI strategies in hospice and palliative care settings, this research can have wide practical implications. This research can provide useful practical tips to leaders as they work on implementing QI projects in their organization.

Originality/value
This manuscript can be of value to leaders, administrators and academicians who are interested in applying QI principles to healthcare processes especially in palliative and hospice care settings. Ability to work with others, solid communication and involvement of employees from all levels can help in streamlining current systems of care.
Safety attitudes in hospital emergency departments: a systematic review
Authors: Alzahrani Naif , Jones Russell , Rizwan Amir , Abdel-Latif Mohamed E. 
Published: August 2019

Purpose
The purpose of this paper is to perform and report a systematic review of published research on patient safety attitudes of health staff employed in hospital emergency departments (EDs).

Design/methodology/approach
An electronic search was conducted of PsychINFO, ProQuest, MEDLINE, EMBASE, PubMed and CINAHL databases. The review included all studies that focussed on the safety attitudes of professional hospital staff employed in EDs.

Findings
Overall, the review revealed that the safety attitudes of ED health staff are generally low, especially on teamwork and management support and among nurses when compared to doctors. Conversely, two intervention studies showed the effectiveness of team building interventions on improving the safety attitudes of health staff employed in EDs.

Research limitations/implications
Six studies met the inclusion criteria, however, most of the studies demonstrated low to moderate methodological quality.

Originality/value
Teamwork, communication and management support are central to positive safety attitudes. Teamwork training can improve safety attitudes. Given that EDs are the “front-line” of hospital care and patients within EDs are especially vulnerable to medical errors, future research should focus on the safety attitudes of medical staff employed in EDs and its relationship to medical errors.
Do the servicescape of public and private hospitals differ? The Malaysian context
Authors: Lai Kim Piew , Chong Siong Choy 
Published: August 2019

Purpose
This study aims to explore if public and private hospitals have differing servicescape attributes.

Design/methodology/approach
The study uses a two-stage (EFA and CFA) procedure for identifying the servicescape attributes and examining their validity in the context of public and private hospitals.

Findings
The findings indicate that, in different contexts, patients would expect different aesthetics of servicescape attributes and how they are influenced by the hospital premises.

Research limitations/implications
It is interesting to note that: not all of the attributes that appear in both contexts are exactly the same; patients do not seem to face difficulties in analysing and interpreting directional cues, even though the spatial orientation in private hospitals is relatively smaller; the way patients of public hospitals draw inference about the ambient conditions is not consistent with private hospitals; and patients perceive that private hospitals pay special attention to developing a built environment that facilitates treatment and recovery process via interior layout, as well as decoration and architecture attributes.

Practical implications
The study grounds the servicescape attributes and provides insights to effectively promote public and private hospitals.

Originality/value
This study may be amongst the first to offer servicescape evidence in both the public and private hospitals.
Dog-assisted intervention at a Spanish university: pilot study
Authors: Peña Gil Diana , García García Mercedes , Camilli Trujillo Celia 
Published: August 2019

Purpose
Dog-assisted interventions (DAIs) are conducted by universities around the world as innovative methods that improve students’ quality of life. The purpose of this paper is to assess the DAI program’s effect on the stress levels, well-being and social skills of first-year students from different degree programs at Complutense University of Madrid (UCM).

Design/methodology/approach
The study was conducted with 64 first-year students (M=19.20, SD=1.57). The intervention consisted of three weekly sessions of 1-h duration interacting with a therapy dog. The investigation followed a quasi-experimental pre-test/post-test design with measures of attitudes toward DAI, perceived stress, well-being and social skills.

Findings
The results indicated significant improvements in all studied variables.

Research limitations/implications
This study presents some limitations. In the design, the authors lack a control group. Another limitation is related to the sample, which was small. The authors also acknowledge that only one measure of each outcome variable was administered. Likewise, during the interventions, external observations should be added that generate qualitative records focused on student–dog interactions. In addition, physiological measures of stress, such as cortisol levels, should be included in the analysis to further support the obtained results. Nevertheless, as this was a pilot study, future investigations should aim to create a program using a larger sample of both participants as well as and dogs, with a linear/longitudinal design to measure both the mid- and long-term effects.

Practical implications
In addition, this pilot study was implemented to assist in the validation and adjustment of the DAI program for UCM students.

Social implications
By using a DAI program, college students have had the opportunity to reduce their stress and develop their social skills, as well as improve their quality of life as individuals and students. Although the implementation of Compludog was small, it was also promising as a pedagogical practice at UCM.

Originality/value
It was applied for the first time in a Spanish university and provided access to therapy dogs within this context.

Abstract

Despite their diversity and their large functional and cultural importance, the patterns and predictors of large mammal diversity along elevational gradients on tropical mountains remain poorly understood. Today, large mammals are threatened by human disturbances such as habitat destruction and hunting and may increasingly depend on the conservation of protected areas.

Here, we use field data on the diversity of large mammals along a 3.6 km elevational gradient on Mt. Kilimanjaro to evaluate the importance of climate, net primary productivity and human impact for the distribution, species richness and community biomass of wild mammals.

Mammal species richness was explored with camera traps on 66 study plots along an elevational gradient from 870 to 4,550 m a.s.l.. We applied path analysis and variance partitioning analysis to unravel the direct and indirect effects of temperature, precipitation, primary productivity, land use, land area, the protection of habitats and the occurrence of domestic mammals on the diversity of wild mammals.

Both species richness and community biomass of wild mammals showed a unimodal distribution with elevation, peaking in the montane zone of Mt. Kilimanjaro. However, the peak shifted significantly to lower elevations when only protected habitats were considered. Wild mammal diversity increased with net primary productivity, protection of habitats and temperature.

Our study underscores the importance of energy resources for the establishment of diversity gradients in large mammals. While temperature has been revealed as a direct predictor of diversity in most ectothermic taxa, in endothermic organisms temperature has stronger indirect effects, via a modulation of net primary productivity. Moreover, our study reveals how patterns of diversity on tropical mountains are influenced by human impact, pointing to the pivotal role of protected areas for the long‐term conservation of mountain biodiversity.

AbstractDNA is one of the fastest growing tools in forensic sciences, increasing reliability in forensic reports and judgments. The use of DNA has increased in different areas of the forensic sciences, such as investigation of plant species, where plastid DNA has been used to elucidate and generate evidence in cases of traceability of genetically modified and controlled plants. Even with several advances and the practice of using DNA in forensic investigations, there are just few studies related to the identification of genetic tools for the characterization of drug and nondrug‐types of Cannabis. Herein, the whole plastomes of two drug‐type Cannabis are presented and have their structures compared with other Cannabis plastomes deposited in the GenBank, focusing in the forensic use of plastome sequences. The plastomes of Cannabis sativa “Brazuka” and of the hybrid Cannabis AK Royal Automatic presented general structure that does not differs from the reported for other C. sativa cultivars. A phylogenomic analyses grouped C. sativa “Brazuka” with the nondrug C. sativa cultivars, while the hybrid Cannabis AK Royal Automatic placed isolated, basal to this group. This suggests that the analysis of plastomes is useful toward genetic identification of hybrids in relation to C. sativa.
Effect of Wind on Horizontal Displacement of Fatal Fall from a Height
Authors: Tsai Wu‐ting , Hu Chia‐I , Chang Chia‐Yun 
Published: August 2019

AbstractThe horizontal displacement of the human body resulting from fatal fall from a height is an important variable commonly used to inversely determine the cause or identify other forensic aspects of the fall. When examining the horizontal displacement, the wind effect is generally ignored. This technical note reports analytical modeling of the falling process, utilizing previous measurements of wind force acting on the human body, for determining the functional relationship between the wind speed and the horizontal displacement in the falling process. The result reveals that it does not take extremely rare wind conditions to cause a considerable shift of the human body, highlighting the importance to consider wind as a factor in investigations of fatal falls.

Published: August 2019

AbstractAimThe aims of the study are to investigate serum neopterin and ischemia modified albumin (IMA) levels in patients with immunoglobulin A vasculitis (IgAV) and evaluate the association of these markers with disease activity and relapse.MethodThirty‐four consecutive adult patients (24 male and 10 female) admitted to the rheumatology clinic and met the IgAV American College of Rheumatology (ACR) criteria were enrolled in this cross‐sectional study. Demographic and clinical features of IgAV and a control group were recorded into a predefined protocol. Disease activity was categorized as “remission” or “active” according to Birmingham Vasculitis Activity Score (BVAS). BVAS ≥ 1 was accepted as "active". Serum neopterin levels, high‐sensitivity C‐reactive protein (hsCRP) and IMA were evaluated according to BVAS and compared to the healthy control group.ResultsSerum median (interquartile range) neopterin, IMA levels and hsCRP were higher in the study group than in control group (2.01 [12.5] ng/mL vs 1.77 [1.37] ng/mL, 0.67 [0.2] ng/mL vs. 0.43 [0.17] ng/mL, 5.6 [17.1] mg/L vs. 1.55 [1.6] mg/L, P = .095, P < .001 and P = .002, respectively). When evaluated according to BVAS, IMA and hsCRP levels were significantly higher in the group with active disease (0.77 [0.12] vs 0.61 [0.13] and 14.85 [4.6], P = .009 and P = .03, respectively). Serum neopterin levels were significantly higher in the active group compared to BVAS (18.95 [32.36] vs 1.63 [1.48], P < .001).ConclusionOxidative stress is important in IgAV pathogenesis. Roles of hsCRP, neopterin and IMA as potential markers of diagnosis and disease activity seem to be worth studying in future studies with larger study groups.

Published: August 2019

ObjectiveElectroconvulsive therapy (ECT)‐induced hippocampal volume change (HVC) has been repeatedly described in recent years. The similar time course of HVC and ECT‐related cognitive effects suggest a relation, that is to date, understudied. This study investigates whether HVC following ECT predicts the change in memory performance six months after the end of the ECT treatment.MethodsHippocampal volume (HV) was measured via high‐resolution 3D T1‐weighted images in 88 patients with late‐life depression, within 1 week before and after ECT. Memory performance was assessed before and six months after ECT. Multiple linear regression was used to examine whether change in memory performance could be predicted based on ECT‐induced changes in HV.ResultsLarger right absolute HVC predicts less pronounced improvement on the VAT (visual memory) in the whole sample. For the 8‐Word Test (verbal memory), Category Fluency Test (semantic memory), and MMSE, the effect is only present in patients who switched from right unilateral to bitemporal stimulation after six ECT sessions. Absolute HVC in the left hemisphere was not significantly related to cognitive change.ConclusionA larger absolute change in right HV during ECT is associated with less improvement in memory performance up to 6 months post‐ECT.

Published: August 2019

AbstractBackground and AimsCompletely substituting e‐cigarettes (EC) for combustible tobacco cigarettes reduces exposure to toxicants and carcinogens. However, a large proportion of EC users (dual users) continue to smoke conventional cigarettes. This study aimed to compare estimated nicotine intake and e‐cigarette use characteristics between exclusive EC users and dual users.DesignWeb‐based anonymous cross‐sectional survey.SettingFrance.ParticipantsA total of 3189 adults, current users of electronic cigarettes (EC). Data collection between 4 October 2014 and 11 November 2014.MeasurementsPrimary outcome: estimated nicotine intake per day (mg) from participants' reports. Secondary outcomes: duration, frequency of EC use and nicotine content of e‐liquids used/day. Dual use was defined as using at least one cigarette per day while also using EC.FindingsA total of 2836 respondents reported exclusive EC use and 353 reported being dual users. Backward stepwise logistic regression showed that dual users had higher estimated combined daily nicotine intake from e‐liquids and cigarettes [estimate: 2.14, standard error (SE) = 0.26, adjusted odds ratio (aOR) = 8.48, 95% confidence interval (CI) = 5.11–14.09, P < 0.001], but lower daily nicotine intake from EC (estimate: –2.14, SE = 0.26, aOR = 0.12, CI = 0.07–0.196, P < 0.001) and reported fewer months of EC use (estimate: −0.31, SE = 0.14, aOR = 0.73, CI = 0.56–0.95, P = 0.022) compared with exclusive EC users.ConclusionDual e‐cigarette users in France may have higher nicotine intake overall than exclusive e‐cigarette users, but they may take in less nicotine from their e‐cigarettes.

Published: August 2019

AbstractObjectiveTo determine what information from community aged care social participation and quality of life assessments needs to be captured, and meaningfully utilised as part of an integrated information and communication technology system.MethodsTwo think tank sessions comprised of community aged care staff and researchers (n = 9) were conducted over 5 weeks. The sessions were guided by the Continuous Quality Improvement framework. Thematic analysis was used to categorise the think tank data.ResultsTo monitor progress over time, participants needed more contextual information captured in the assessment forms, such as client goals and outcomes of assessments. The aged care provider agreed to embed outcome measure score and action following assessment into its information and communication technology system.ConclusionCollaboration between aged care staff and researchers resulted in adjustments to the aged care provider's information and communication technology system to better target the monitoring and planning of its clients' psychosocial needs.
