AbstractSeed longevity is one of the most essential characters of seed quality. Two Chromosome segment substitution lines (CSSL) I178 and X178 with significant difference on seed longevity were subjected to transcriptome sequencing before (0d-AA) and after five days of accelerated ageing (5d-AA) treatments. Compared to the non-accelerated ageing treatment (0d-AA), 286 and 220 differential expressed genes (DEGs) were identified in I178 and X178, respectively Among those, 98 DEGs were detected in both I178 and X178 after 5d-AA, Enriched GO terms included cellular components of cell part, intracellular part, organelle and membrane etc., including carbohydrate derivative catabolic process, carbohydrate synthesis, sugar isomerase (SIS) family protein etc. Transcriptome analysis of I178 and X178 showed that Alternative splicing (AS) occurs in 63.6% of the expressed genes in all samples. Only 381 genes specifically occurred AS in I178 and X178 after 5d-AA, mostly enriched in nucleotide and nucleoside binding. Combined with the reported QTL mapping result, the DEG and the AS information, 13 DEGs in the mapping intervals and 7 AS-DEGs were potential candidates may directly or indirectly associated to seed ageing.
Encountering relatable information in experiential learning spaces
Authors: Miller Faye Q. 
Published: May 2019

PurposeThe purpose of this paper is to provide an emerging framework for university libraries’ research and reference services, which aims to strengthen partnerships between research information specialists and early career researchers (ECRs).Design/methodology/approachThe conceptual model used in this paper was originally developed from a constructivist grounded theory study, analyzing data from a sample of ECRs across multiple disciplines at two universities and contextualized by a review of recent research into ECRs’ information experiences, and researcher–librarian partnerships in experiential learning spaces within and beyond libraries.FindingsThis paper provides a review of the literature on one aspect of the knowledge ecosystem model relevant to research information specialists: tangible forms of information such as texts, tools, humans, cultures and environments encountered during informal learning experiences in six spaces: professional development programs, formal coursework, events, community, home and social media.Research limitations/implicationsThis paper is a catalyst for discussions and research into how research information specialists can facilitate access to the forms of information and learning experienced by ECRs, and what research information specialists can do with tangible information to respond to ECRs needs for experiential learning.Practical implicationsAs the previous study found that ECRs perceived their knowledge as vital resources toward their research career progression, it would be useful for research information specialists to understand and design services paying attention to the importance of ECRs’ initial encounters with tangible information to create the knowledge they need.Social implicationsWorking toward improved engagement and partnership through increased awareness and understanding of informed learning experiences between ECRs, their mentors and other developers and research librarians/information specialists can result in higher quality development and communication of new research, which can impact on society’s innovation and advancement.Originality/valueThe new integrative framework presented in this paper can assist in terms of identifying what informs ECRs professional development toward strengthening ECR and librarian/information specialist partnerships.
System dynamics modeling with fuzzy logic application to mitigate the bullwhip effect in supply chains
Authors: Poornikoo Mehdi , Qureshi Muhammad Azeem 
Published: May 2019

Purpose
A plethora of studies focused on the cause and solutions for the bullwhip effect, and consequently many have successfully experimented to dampen the effect. However, the feasibility of such studies and the actual contribution for supply chain performance are yet up for debate. This paper aims to fill this gap by providing a holistic system-based perspective and proposes a fuzzy logic decision-making implementation for a single-product, three-echelon and multi-period supply chain system to mitigate such effect.

Design/methodology/approach
This study uses system dynamics (SD) as the central modeling method for which Vensim® is used as a tool for hybrid simulation. Further, the authors used MATLAB for undertaking fuzzy logic modeling and constructing a fuzzy inference system that is later on incorporated into SD model for interaction with the main supply chain structure.

Findings
This research illustrated the usefulness of fuzzy estimations based on experts’ linguistically and logically defined parameters instead of relying merely on the traditional demand forecasting based on time series. Despite the increased complexity of the calculations and structure of the fuzzy model, the bullwhip effect has been considerably decreased resulting in an improved supply chain performance.

Practical implications
This dynamic modeling approach is not only useful in supply chain management but also the model developed for this study can be integrated into a corporate financial planning model. Further, this model enables optimization for an automated system in a company, where decision-makers can adjust the fuzzy variables according to various situations and inventory policies.

Originality/value
This study presents a systemic approach to deal with uncertainty and vagueness in dynamic models, which might be a major cause in generating the bullwhip effect. For this purpose, the combination between fuzzy set theory and system dynamics is a significant step forward.

Authors: Štrukelj Tjaša , Zlatanović Dejana , Nikolić Jelena , Sternad Zabukovšek Simona 
Published: May 2019

PurposeThe purpose of this paper is to prove that it is possible and necessary that higher education institutions develop appropriate competencies of students during the learning process as required by the practice if teachers use the systemic approach and cybernetics knowledge. The authors especially research the importance of competence entrepreneurship and how to stimulate entrepreneurship by developing competencies of creativity, teamwork and communication.Design/methodology/approachBased on systems theory, transversal competencies entrepreneurship, creativity, teamwork and communication, as well as their interdependence, were requisitely holistic selected. In the selection of diverse contemporary learning methods, the authors started from an action research approach that implies learning by doing, i.e. participation of students. With the use of statistical methods, the authors showed that a cyber-systemic requisite holistic learning action approach based on interdependence of teacher and students learning process results in innovation of researched transversal competencies.FindingsBased on two quantitative and qualitative researches of 96 students’ competencies, the authors found out that when using contemporary learning methods, the desired results can be achieved. In described learning process everyone involved gained: both the teacher and the students.Research limitations/implicationsThe survey does not include verifying the usefulness of developed competencies in practice. Also, the study only covers the findings of the research study of one academic year.Practical implicationsThe research is important for the practice of higher education, as it demonstrates that the teacher is with a targeted focus on the selected viewpoints able to effectively improve students’ competencies.Social implicationsIf higher education’s institutions take a strategic decision to target improvement of the transversal competencies of students, they will be easier and faster to employ, and practice will get more relevant employees. The economy will be more efficient and effective.Originality/valueAccording to the authors’ knowledge, no research measures the development of selected transversal competencies using the contemporary learning methods, based on cyber-systemic learning action approach. The authors found out that the methods used have influenced the final results, which show that all measured students’ transversal competencies have improved.
Trade books’ evolving depictions of Thomas Jefferson, America’s third president
Authors: Bickford John H. , Lindsay Megan , Hendrickson Ryan C. 
Published: May 2019

Purpose
History-based trade books are an essential classroom option for social studies and English teachers. Professional organizations in history, social studies, English, reading and literature promote these engaging, age-appropriate secondary sources. Research suggests that misrepresentations appear often within history-based curricula, yet the majority of empirical studies have been completed on textbooks. The purpose of this paper is to examine the historical representation of Thomas Jefferson within trade books.

Design/methodology/approach
The data sample included trade books targeting various ages to make comparisons within and between grade ranges; the authors selected books published in distinctly different years to examine how Jefferson’s historical representation changed over time. The mixed methods content analysis used both open coding and axial coding.

Findings
Findings included sanitized versions of slavery at Monticello and omissions of his relationship with Sally Hemings. Date of publication, particularly those published after 1999 as new scientific evidence emerged linking Hemings and Jefferson, and intended audience shaped patterns of representation about Jefferson’s privileged social position, authorship of the Declaration of Independence, political philosophy and involvement in the American Revolution, to mention a few. Heroification, a common historical misrepresentation, did not appear.

Research limitations/implications
Limitations included: uneven portions of the data pool as children’s and young adult trade books were not common in early and mid-twentieth century; organization of books by grade range is problematic due to inexact nature of ranking narratives’ complexity; and definitive conclusions cannot emerge from a single study. Future research should consider how trade books represent other historical figures, particularly slave-owning American presidents.

Practical implications
Practical suggestions, such as how to address misrepresentations using primary sources, are offered.

Originality/value
Thomas Jefferson, undoubtedly an impactful American, is frequently included in elementary, middle level and high school curriculum. The authors examined Jefferson’s historical representation within trade books.
Moderating role of innovation culture in the relationship between organizational learning and innovation performance
Authors: Ghasemzadeh Peivand , Nazari Jamal A. , Farzaneh Mandana , Mehralian Gholamhossein 
Published: May 2019

Purpose
Different studies have analyzed the relationship between organizational learning (OL) and innovation performance (IP). However, the question of how innovation culture (IC) affects the relationship between OL and IP remains unexplored. This study aims to examine the impact of IC on the relationship between OL and various dimensions of IP, including product, process and objective innovation.

Design/methodology/approach
A research model was developed and performed based on the relevant literature in the field of OL, IC and IP. The hypotheses are tested with the data collected from companies operating in an intensive knowledge-based industry.

Findings
Based on the results of 625 questionnaires completed by pharmaceutical companies, OL activities and IC can result in product and process innovation. However, this relationship was not supported for the objective innovation. Furthermore, in terms of the moderating role of IC in the relationship between OL and IP dimensions, the results were significant.

Practical implications
The findings help to gain a better understanding of how organizational commitment by creating a culture for innovation can help to maximize the benefits of continuous OL in product and process innovation.

Originality/value
Considering the three aspects of IP, it is the first survey of the contribution of OL in firms’ IP with considering the moderating role of IC. The proposed model would enrich the relevant literature and provide us with better understanding how OL contributes to the IP.
Environmental regulations and their effect on innovation and competitiveness in tourism in Barbados, Guyana and Jamaica
Authors: Huntley Lewis Eritha Olinda 
Published: May 2019

Purpose
This paper aims to explore the need for innovation in Caribbean tourism with stringent (mandatory) environmental regulations as the key driver of the process. It draws examples from three destinations, Barbados, Guyana and Jamaica.

Design/methodology/approach
This assessment entailed a review of the literature on the key issues. Theories on innovation, regulations and competitiveness were examined in brief. The paper also presents an overview of Caribbean tourism to provide context. Of note is the dearth of information on the drivers of innovation and its effect on the Caribbean tourism industry which was a major limitation of this assessment.

Findings
The main implication of this review is that it attempts to highlight the need for discourse on the effective use of environmental regulations to influence the behaviour of industry operatives towards achieving sustainable tourism. Within the context of climate change and the threat that this poses to Caribbean tourism, there is the critical need for this discourse. Consideration is also given to the value stringency of regulation since it is theorised that, if applied correctly, this may be the impetus to drive businesses to innovate to be competitive.

Originality/value
This is a novel approach to the management of the tourism industry which has shown a preference for self-regulation. Given the proposed outcome, the paper advocates mandatory, stringent regulations since self-regulation is a choice left solely to the industry operatives.
Earning the “Write to Speak”: Sell‐Side Analysts and Their Struggle to Be Heard
Authors: Spence Crawford , Aleksanyan Mark , Millo Yuval , Imam Shahed , Abhayawansa Subhash 
Published: May 2019

ABSTRACTThis paper explores the ways in which sell‐side (SS) financial analysts seek to position themselves advantageously within the wider field of investment advice in spite of widespread skepticism over the value that their forecasts and recommendations add to investment decisions. The field of investment advice has been characterized in recent years by a number of regulatory and technological changes that have forced SS analysts to reconstitute the ways in which they influence the investment decisions of buy‐side (BS) actors. Faced with existential threats, SS analysts have responded to the disruptive impact of technology and regulation by struggling hard to ensure that their services are still valued by fund managers. Key to this ongoing process is the recalibration of professional expertise, which previous research has alluded to but not explored in detail. Central to the persistence of SS analysts in processes of investment decision making are activities revolving around the production and use of analyst reports which, our findings indicate, are less valuable for their informational content than their role as “relational devices,” ascribing legitimacy to SS analysts and earning them an entry ticket to more substantive, value‐adding interactions with companies and BS actors. We also show that economic considerations in the area of investment advice are influenced by social ties, the motivations of various actors in the field, and their relative position vis‐à‐vis other actors. More generally, we contribute to the literature on professional projects by showing how professional groups are constantly engaged in attempts to reposition themselves in the social space, but that field‐level changes can restrict the outcomes of these strategies to mitigation rather than advancement for the professionals concerned.
How Getting the Facts Right Can Fuel Partisan‐Motivated Reasoning
Authors: Bisgaard Martin 
Published: May 2019

AbstractScholars often evaluate citizens' democratic competence by focusing on their ability to get relevant facts right. In this article, I show why this approach can yield misleading conclusions about citizen competence. I argue that although citizens with strong partisan loyalties might be forced to accept the same facts, they find alternative ways to rationalize reality. One such way, I show, is through the selective attribution of credit and blame. With four randomized experiments, conducted in diverse national settings and containing closed‐ as well as open‐ended questions, I find that as partisans correctly updated economic beliefs to reflect new facts, they conversely attributed responsibility in a highly selective fashion. Although partisans might acknowledge the same facts, they are apt in seizing on and producing attributional arguments that fit their preferred worldviews.
A study of temperature control in different designs of emergency drug transport bags
Authors: Dingley J. , Thatcher N. , Williams D. 
Published: May 2019

SummaryWe investigated whether low melting point phase‐change waxes could be incorporated into emergency drug transport bags to attenuate the known temperature extremes their contents can be exposed to. We exposed two custom‐made hollow‐walled drug containers placed within a pair of drug transport bags to three day/night cycles including periods of direct radiant sunlight. The wall cavities of one contained air, whereas those of the other contained a paraffin wax (melting point of 44–46 °C) with a high latent heat of fusion (until fully melted, its temperature does not increase further). We collected 25,920 temperature datasets at six locations. We found that 97.8% and 84.7% of ampoule temperatures within the wax and air cavity containers, respectively, were within a target range of 15–40 °C over the study duration (Levene statistic W = 4279.1; Levene's test for equality of variance, p < 0.001). Ampoule temperatures in the wax cavity container only exceeded 40 °C for 1.7% of the time. Even when they did so, their temperature was attenuated to 40.3 °C, despite an ambient air temperature of > 40 °C for 6.4% of the time (peak 46.9 °C) and a bag surface temperature of > 40 °C for 17.2% of the time (peak 64.4 °C). In contrast, the ampoule temperature in the air cavity container exceeded 40 °C for 17.1% of the time (peak 54.1 °C). The latent heat of fusion of phase‐change materials may be exploited in the design of drug transport bags to mitigate any temperature changes in the drugs stored within them.
Orchestrating the antioxidant defenses in the epididymis
Authors: O'Flaherty C. 
Published: May 2019

AbstractBackgroundDuring the post‐testicular maturation that occurs in the epididymis, spermatozoa need to face biochemical and morphological changes that may make them vulnerable to oxidative damage. During spermatogenesis and the epididymal maturation, the spermatozoon acquires antioxidant enzymes needed to face possible increases of reactive oxygen species (ROS) produced by its own aerobic metabolism but also due toROSproduced in high quantities by abnormal spermatozoa.ObjectivesProvide an up‐to‐date review of the enzymatic antioxidant system in the epididymis.Material and methodsA thorough literature review was performed for papers concerning the players of the antioxidant defenses in the epididymis.ResultsThe antioxidant system in the epididymis is composed by superoxide dismutases, catalase, glutathione peroxidases, peroxiredoxins, glutathione‐S‐transferases, thioredoxins and thioredoxin reductase. They work together to maintain low levels ofROSduring the epididymal maturation. Knockout models revealed that the absence of one of the enzyme impact sperm quality affecting a variety of proteins involved in motility, the ability to fertilize oocyte, and promotes oxidative damage to the spermDNA.Discussion and conclusionsThese findings suggest that each enzyme is playing a specific role, and in most of the cases, no compensatory mechanisms are put in place when one enzyme is absent. This review highlights the different antioxidant enzymes in the epididymis and their role during maturation of the spermatozoon.
Open Population Maximum Likelihood Spatial Capture-Recapture
Authors: Glennie Richard , Borchers David L. , Murchie Matthew , Harmsen Bart J. , Foster Rebecca J. 
Published: May 2019

Abstract
Open population capture-recapture models are widely used to estimate population demographics and abundance over time. Bayesian methods exist to incorporate open population modeling with spatial capture-recapture (SCR), allowing for estimation of the effective area sampled and population density. Here, open population SCR is formulated as a hidden Markov model (HMM), allowing inference by maximum likelihood for both Cormack-Jolly-Seber and Jolly-Seber models, with and without activity center movement. The method is applied to a 12-year survey of male jaguars (Panthera onca) in the Cockscomb Basin Wildlife Sanctuary, Belize, to estimate survival probability and population abundance over time. For this application, inference is shown to be biased when assuming activity centers are fixed over time, while including a model for activity center movement provides negligible bias and nominal confidence interval coverage, as demonstrated by a simulation study. The HMM approach is compared with Bayesian data augmentation and closed population models for this application. The method is substantially more computationally efficient than the Bayesian approach and provides a lower root-mean-square error in predicting population density compared to closed population models.
