Authors: Kanapathy Suganty , Lee Khai Ern , Mokhtar Mazlin , Syed Zakaria Sharifah Zarina , Sivapalan Subarna , Mohd Zahidi Azizah 
Published: September 2019

Purpose
This paper aims to discuss the knowledge levels, attitudes and behaviours regarding the concept of sustainable development among pre-university programme educators, as well as the potential barriers and opportunities they face in adopting the concept of sustainable development in the teaching of the pre-university level chemistry module at a public university in Malaysia.

Design/methodology/approach
A survey was conducted with eight educators of a pre-university programme at a public university located in Selangor, Malaysia. This pre-university programme exposes students to advanced courses in science, which are very much like first-year university courses for candidates who are interested in gaining admission to degree programmes. For this study, the focus was on chemistry educators only. The collected data were analysed through descriptive analysis following which interviews were conducted with the respondents.

Findings
In general, the educators have good knowledge and attitudes towards the concept of sustainable development. Moreover, their projected knowledge (K), attitude (A) and behaviour (B) focus more on environmental dimensions, as opposed to other sustainable development dimensions. While the integration of the concept of sustainable development in chemistry teaching is restricted by a few barriers, such as content-based learning, lack of guidebooks related to sustainable development and an overcrowded curriculum, positive responses from the chemistry educators indicate that there are opportunities to implement sustainable chemistry concepts in the pre-university chemistry module.

Research limitations/implications
The present study was conducted with several limitations; the data were obtained from a small sample size at an institute located within a public university. The respondents of this research consisted of only three existing chemistry educators and five administrators who are also educators. Further studies about sustainable chemistry teaching should include samples from other public and private universities.

Originality/value
This paper is instrumental in assisting the Ministry of Education, administrators, as well as educators within the pre-university sector to shift their goals towards sustainable chemistry teaching to achieve success in education for sustainable development.
Mobile phone vs paper-pencil mode of note-taking, a case study among the students of Bankura University
Authors: Kundu Arnab , Bej Tripti 
Published: September 2019

PurposeThe purpose of this study is to recommend the university authorities to build better teaching-learning environment for its students to use variables and multiple note-taking methods in class for best results fundamental in each method.Design/methodology/approachThe study is a case study that follows a ‘problem-driven’ approach concerned specifically with providing practical solutions to real-world problems. A sample size of 320 respondents was obtained, in which 300 were university students selected from the first, second and third years of study and 20 were professors.FindingsThis case study made it very obvious to all that mobile phone note-taking is a regular practice among students at Bankura University. At the same time, the study also reveals that the practice does not significantly differ based on students’ sex.Research limitations/implicationsBased on the findings, the study recommends for the need to educate students on the importance of paper and pencil note-taking method so that they do not fall prey to such risks. A befitting environment should be created so that students can use various methods of note-taking in classrooms avoiding their negative impacts.Practical implicationsIt has a wide implication in the modern age where cutting-edge technologies are shaping our course actions every day. We cannot keep ourselves from this technological association and our mobile phones have become our friend, philosopher and guide. In this scenario, this study bears a big implication in itself.Originality/valueThis study is based on the authors’ ground study and is purely original and unique in the true sense.
Modelling advances in gatekeeping theory for academic libraries
Authors: Ojennus Paul 
Published: September 2019

Purpose
The purpose of this paper is to evaluate the appropriateness of gatekeeping theory, particularly its recent elaboration in journalism and communication studies for the investigation of information flows in academic libraries.

Design/methodology/approach
This paper uses the methods of conceptual analysis and thought experiment.

Findings
This paper finds that current elaborations of gatekeeping theory are useful for modeling library information flows, particularly identifying and evaluating influences on those flows. It is able to reframe intransigent issues around library neutrality and open access so that more nuanced approaches can be constructed.

Originality/value
Gatekeeping theory as elaborated by Shoemaker and Vos for journalism and communication studies, while occasionally referenced the library and information science (LIS) literature, has not been previously evaluated as a framework for library information flows. This is the first paper to assess the potential of aspects of the theory such as levels of analysis and multiplicity of channels to reframe issues in LIS.
Dark tourism consumption in Mexico City: a new perspective of the thanatological experience
Authors: Speakman Mark 
Published: September 2019

Purpose
The Euro-centric nature of dark tourism research is limiting the perspective and restricting the scope of contemporary theory. Hence, this paper aims to explore how dark tourism consumption differs in a society apart from the Anglo/Eurosphere. This is done by testing Stone and Sharpley’s (2008) thanatological framework in Mexico, a country whose residents are renown for having a unique perspective on death, to assess whether Mexican dark tourism consumers undergo a similar, or different, thanatological experience to that proposed in the framework.

Design/methodology/approach
The study adopts a qualitative approach in the form of a case study. The opinions of Mexican dark tourism consumers were gained by using the technique of semi-structured interviewing in four separate dark tourism sites within Mexico City, with coding serving as the form of analysis.

Findings
The findings show that due to the non-existence of an absent/present death paradox in Mexican society, the research participants experienced a thanatological process that contrasts with those from Western societies, which indicates that the thanatological framework is unsuitable in the context of Mexican dark tourism. At the same time, the study contests the common perception that Mexicans have a jovial familiarity with death, and demonstrates that in this case the thanatological process confirmed an acceptance of death, rather than any kind of intimacy.

Originality/value
The research is valuable in that it is a response to recent calls for research in geographical locations not previously considered in a dark tourism/thanatology context.
Library information services in academic libraries of Azerbaijan: a comparative study
Authors: Ismayilov Khalil , Ismayilov Nadir , Mammadova Vafa 
Published: September 2019

Purpose
The purpose of this paper is to comparatively study the library and information services provided by three academic libraries – Baku State University Scientific Library, ADA University Library and Information Services and Khazar University Library and Information Center – located in Baku, Azerbaijan. Various types of library services are examined in terms of funding, acquisition and technical equipment support issues. Also, different subordination conditions (public/private) of the universities help to better understand the current position of academic libraries in different entities.

Design/methodology/approach
Most part of the conveyed information was obtained through review of related literature, libraries’ annual reports and personal communication with the directors of the academic libraries, to look for similarities and differences in provided library and information services. The results of the study are comparatively described through multiple tables and charts.

Findings
For improving services it is necessary to develop paid forms of library and information services, maintain various training possibilities for library staff in modern librarianship areas, increase the variety and number of public and outreach activities.

Research limitations/implications
As the findings of the paper suggest new forms of library services and activities, it is necessary to continue the topic in further studies to develop practical methods and applications for local library conditions.

Originality/value
The paper can be accepted as the first comparative study of the library information services in academic libraries of Azerbaijan, which gives general overview and analysis of separate service ranges and types. The researchers interested in Azerbaijani librarianship may find it practical.
Towards the ethical librarian
Authors: Amoah Gloria Bosomtwi , Yeboah Eugene Baah 
Published: September 2019

Purpose
The purpose of this paper is to examine the perspectives and viewpoints of professional staff of the Sam Jonah Library in as much as the ethical aspects of their profession are concerned. The paper also seeks to determine the common ethical issues that confront these professionals and their default courses of action in dealing with these issues.

Design/methodology/approach
The descriptive survey design was used as the research methodology with the population of the study being all professional (post-graduate diploma and above) and para-professional (certificate, diploma and first degree) staff of the library. Due to the small number of professional staff (43) in the library, the census sampling technique was used.

Findings
Results indicated the existence of ethical dilemmas in the working lives of these professionals with guidance for dealing with these dilemmas emanating mostly from consultation of senior colleagues. Although the findings showed that the Ghana Library Association (GLA) had an ethics handbook, it was revealed that majority of the staff were not aware of its existence. It was also discovered that one of the major challenges of these professionals is the absence of a specific library code of ethics handbook to guide staff in case they are confronted with these ethical dilemmas. The study recommends a strong awareness creation initiative from the GLA to bring to the notice of members, the existence of a formal code of ethics document.

Originality/value
The paper provides information on specific ethical issues confronting staff of the library and their current modes of dealing with the dilemmas they encounter.
Understanding the psychological drivers of loneliness: the first step towards developing more effective psychosocial interventions
Authors: Robertson Guy 
Published: September 2019

Purpose
The purpose of this paper is to outline the need to develop a more balanced approach to addressing the loneliness experience by older people by recognising the psychological and emotional dynamics which cause it. It proposes a more holistic psychosocial approach to loneliness.

Design/methodology/approach
This paper draws on and reviews the published literature on the psychological aspects of loneliness.

Findings
Although not extensive, there is sufficient evidence to begin to develop and test more psychosocial approaches to addressing loneliness.

Research limitations/implications
The evidence base is not extensive and a fair degree of it has not been fully trialled with older people.

Practical implications
There is an a priori case for using the evidence that exists to develop and test out new psychosocial interventions for addressing loneliness.

Social implications
It is possible that a more psychosocial approach to loneliness will enable more to be done to address the significant distress of older people experience severe and chronic loneliness. It may also be possible to develop more effective preventative strategies which build resilience in older people.

Originality/value
The field of loneliness practice and research is overwhelmingly based on sociological analysis and social interventions. This paper is one of the first to explicitly highlight the value in drawing from psychological data in order to develop psychosocial approaches.
Additive manufacturing by material extrusion with medical grade silicone elastomers and IR laser curing
Authors: Porter Daniel A. , Davis Nicholas , Krueger Paul S. , Cohen Adam L. , Son David 
Published: September 2019

Purpose
Techniques of extrude and cure additive manufacturing for thermally cured, high viscosity and medical-grade silicone are investigated by using a small ram extruder and a near-infrared (IR) laser. The purpose of this study is to evaluate the process parameter effects on the stiffness of the final products.

Design/methodology/approach
Process parameter effects on axial stiffness values and durometer are explored. Parameters such as extrusion layer height, laser speed, laser current, laser raster spacing and multiple laser passes were investigated and compared to traditional cast and cure methods. Dimensional changes were also recorded and compared.

Findings
Tensile and durometer tests show that certain curing parameters give tensile stress and durometers within 10 per cent of bulk material specifications at 200 per cent strain. Parameters that had the highest impact on tensile stress at 200 per cent strain were layer height (0.73 per cent) followed by laser power (0.69 per cent), and then laser raster spacing (0.45 per cent). Parameters that had the highest impact on durometer were laser power (1.00 per cent), followed by layer height, (0.34 per cent) and then laser raster speed (0.32 per cent). Three-dimensional printed samples had about 11.2 per cent more shrinkage than the bulk cast samples in the longest dimension.

Originality/value
This paper is one of the first that demonstrates near IR laser curing parameter effects on three-dimensional printed, commercial off-the-shelf, medical-grade and viscous silicone. The ability to cure very viscous thermosets locally enables interesting technologies such as wire encapsulation, high voltage actuators and drug delivery devices.
The spatial complexity of seed movement: Animal‐generated seed dispersal patterns in fragmented landscapes revealed by animal movement models
Authors: Nield Andrew P. , Nathan Ran , Enright Neal J. , Ladd Philip G. , Perry George L. W. 
Published: September 2019

AbstractLarge animals provide crucial seed dispersal services, yet face continued threats and are susceptible to changes in landscape composition and configuration. Thus, there is a growing imperative to improve understanding of animal‐generated seed dispersal using models that incorporate spatial complexity in a realistic, yet tractable, way.We developed a spatially explicit agent‐based seed dispersal model, with disperser movements informed by biotelemetry data, to evaluate how landscape composition and configuration affect seed dispersal patterns. We illustrated this approach for the world's second largest ratite, the emu (Dromaius novaehollandiae), a highly mobile generalist frugivore considered an important long‐distance disperser for many plant species across Australia.When animal movement is unrestricted, model parameters related to seed gut passage largely determine seed dispersal kernels. However, as habitat loss and fragmentation increase, the extent of long‐distance dispersal events is reduced and seed shadows became progressively more aggregated. This effect is due to the emu not being able to move between disconnected parts of the landscape, with small changes in habitat structure causing decreased long‐distance dispersal.We simulated seed dispersal patterns generated by three commonly used generic models of animal movement – unbiased and biased correlated random walks and Lévy walks – to evaluate how different representations of movement affect estimations of animal movements and emergent seed dispersal patterns. Simulated movements informed by the emu biotelemetry data resulted in longer median seed dispersal distances than do the three generic models.Synthesis.Changes in landscape composition and configuration can dramatically alter patterns of zoochorous seed dispersal as they influence animal movement. However, when models are used to simulate the patterns of seed dispersal, decisions about how animal movement is represented also affect estimates of seed dispersal.

Published: September 2019

BackgroundMany formulas based on the patient's height, weight and/or age exist to determine central venous catheter (CVC) depth in children. However, this information is unavailable in some emergency conditions. Therefore, direct methods should be developed to guide catheter position in children.MethodsEighty patients aged 1–10 y were enrolled from July 2015 to August 2016 and seventy‐five were completed; fifty were male, and twenty‐five were female. The exclusion criteria were inability to identify the sternal angle or failure to use the right internal jugular vein approach. The catheter was inserted using the right internal jugular vein approach, the distance from the skin puncture point to the midpoint of the sternal angle plane was measured, and the catheter tip was positioned to this distance minus 1 cm. Chest radiography were performed for those children after catheter insertion. The relative position between the catheter tip and carina was confirmed and the longitudinal distance from the catheter tip to the carina was calculated on radiographic images, and related complications were recorded.ResultsAll catheter tips were above the carina, and the average distance from the catheter tip to the carina was 9.8 mm. No patients experienced serious complications.ConclusionThe sternal angle is a useful and reliable anatomic landmark for guiding CVC position in children. Using this landmark, the catheter can be quickly and conveniently placed at a safety position in right internal jugular vein, especially in some emergency conditions.

Published: September 2019

AbstractBackgroundEducation and training in Allergy and Clinical Immunology (A/I) are characterized by a great variability worldwide. However, objective and worldwide data regarding this topic are lacking.MethodsTo investigate personal information, education, and involvement in scientific societies of juniors engaged in A/I field, a questionnaire was developed by representatives from the JMs’ boards of the European Academy of Allergy and Clinical Immunology (EAACI), the American Academy of Allergy, Asthma, and Immunology (AAAAI), and the World Allergy Organization (WAO).ResultsA total of 543 questionnaires were collected from 76 regions of all continents. The geographic distribution of responders was as follows: Africa‐Middle East 3.0%, Asia‐Pacific 21.4%, Europe 48.2%, Latin America 12.1%, and North America 15.3%. 59.0% of responders declared that A/I is recognized as a separate specialty in their country, Europe mostly accounting for that proportion. Primary interest in the field represents the main motivation for choosing A/I specialty. Concerning involvement in scientific societies, 41.1% of responders ever attended an EAACI Congress, 20.6% an AAAAI Congress, and 20.4% a WAO Congress. According to 40.3% of responders, scientific societies do not provide enough opportunities for young members, and 96.4% believes in a more intensive cooperation between the A/I Societies.ConclusionsThe survey provides the first worldwide perspective about A/I specialty. It represents the first ever example of a structured collaboration between the junior members (JMs) of the three main A/I Societies. The findings suggest the need for harmonization, at least in terms of training and formation in the field of A/I worldwide.
Different thickening complexes with pectin in infant anti‐regurgitation formula
Authors: Dupont Christophe , Vandenplas Yvan 
Published: September 2019

AbstractAimTo summarise the results from four clinical trials assessing the efficacy and safety of a thickening complex in the management of regurgitation in infants.MethodsInfants (n = 392) younger than 5 months presenting with at least five regurgitations per day were recruited in four open‐label, interventional, single‐group, multi‐centric clinical trials sharing an identical design. The efficacy of four different formulae thickened with different thickening complexes of pectin, starch and locust bean gum, was evaluated on regurgitation at days 3, 14 and 90, and stools and growth at days 14 and 90.ResultsThe daily number of regurgitation episodes was significantly reduced at days 3 and 14 vs baseline in all studies (P < .001), with the largest decrease with the formula having the highest pectin content (study 1; P < .001). In all studies, growth was within normal range. A trend towards stool normalisation for consistency was observed in three studies at day 90 vs baseline and was significant in study 1 (P < .001). Stool frequency was unchanged by the interventions.ConclusionThe four tested thickened formulae reduced regurgitation and were proven to be safe. The formula with the largest amount of pectin and lowest starch content showed the best efficacy.
Vascular and inflammatory mineralocorticoid receptors in kidney disease
Authors: Barrera‐Chimal Jonatan , Jaisser Frederic 
Published: September 2019

AbstractMineralocorticoid receptor (MR) activation in the kidney can occur outside the aldosterone‐sensitive distal nephron in sites including the endothelium, smooth muscle and inflammatory cells. MR activation in these cells has deleterious effects on kidney structure and function by promoting oxidative injury, endothelial dysfunction and stiffness, vascular remodelling and calcification, decreased relaxation and activation of T cells and pro‐inflammatory macrophages. Here, we review the data showing the cellular consequences of MR activation in endothelial, smooth muscle and inflammatory cells and how this affects the kidney in pathological situations. The evidence demonstrating a benefit of pharmacological or genetic MR inhibition in various models of kidney disease is also discussed.
