Supportive campuses and first-generations-student learning outcomes
Authors: Wright Brian 
Published: February 2019

PurposeThe purpose of this paper is to analyze the relationship between supportive campus measures and student learning outcomes for first-generation students and non-first generation students to determine if variances are present. A lack of social capital of first generation when compare to non-first-generation students is theorized to be a contributing factor driving differences between the two groups.Design/methodology/approachResearch survey design using penalized regression methods to quantify differences between groups. The analysis used 10 years of student engagement data.FindingsFinal analysis showed that first-generation student outcomes had little to no significant connection with the administrative focused aspects of the campus environment as compared to non-first-generation that represented highly significant relationships. This results supports the theory that first-generation students may simply be unaware of how to leverage these resources do to social capital disadvantages.Practical ImplicationsThe result suggests that universities should reconsider first-generation programs to ensure that they have the capability to address first-generation students’ lack of social capital. The primary method by which social capital is generated is through networking or peer groups expansion. Consequently, first-generation students might benefit greatly from student mentors that are not first-generation students to help aid in the transition to college as compared to participating in programs that group and isolate first-generation students together.Originality/valueVery few studies have attempted to use social capital as a theoretical framework to explain differences in how first-generation and non-first-generation student learning outcomes relate to campus engagement variables. Moreover, no studies have used both penalized regression and bootstrap validation in addressing this issue, making the study original in design and analysis.
Gender diversity and firm value: evidence from UK financial institutions
Authors: Agyemang-Mintah Peter , Schadewitz Hannu 
Published: February 2019

PurposeThe purpose of this paper is, first, to empirically examine whether the appointment of females (board gender diversity) to the corporate boards of UK financial institutions can improve firm value, and second, to examine whether having females on the boards of UK financial institutions can impact firm value during the pre-/post-global financial crisis periods.Design/methodology/approachThe paper uses secondary data obtained from DataStream covering 63 financial institutions over a period of 12 years. A number of additional statistical estimations, including random effects and fixed effects, are conducted to test the robustness of the findings.FindingsThe outcome of this empirical research shows that the presence of females on the corporate boards of UK financial institutions has a positive and statistically significant relationship with firm value. The authors’ evidence reveals a positive and statistically significant impact on the firm’s value prior to the financial crisis, that is, during the pre-crisis period (2000-2006), meaning that women contributed significantly to the firm’s value. However, after the financial crisis, the presence of females on the board had no significant effect on the firm’s value. A reasonable explanation may be that, whilst the financial crisis was over in the period 2009-2011, the entire UK economy was still experiencing an economic downturn, and financial firms were no exception, irrespective of whether there was female representation on any corporate board. Overall, the findings are consistent with the prior studies.Practical implicationsThe results have practical implications for governments, policy-makers and regulatory authorities, by indicating the importance of women to corporate success.Originality/valueDespite several research projects on board gender diversity (BGD), this research is unique compared to the previous empirical studies, primarily because it is the first-time research of this nature is empirically ascertaining BGD and firm value in UK financial institutions, also during the pre-/post-financial crisis era. This paper contributes to the corporate governance literature by offering new insights on board diversity and firms’ value relationship. Overall, the results help fill any gaps on gender diversity and firm value in UK financial institutions.
Does XBRL disclosure management solution influence earnings release efficiency and earnings management?
Authors: Hsieh Tien-Shih , Wang Zhihong , Abdolmohammadi Mohammad 
Published: February 2019

Purpose
This study aims to investigate whether eXtensible Business Reporting Language (XBRL) disclosure management solution improves public companies’ earnings release efficiency and mitigates earnings management.

Design/methodology/approach
This study adopts a unique survey data set from the Financial Executives Research Foundation 2013 to identify companies’ XBRL implementation strategies. Earnings release efficiency is measured by earnings announcement time lag. Multiple indicators of both accruals- and real activities-based earnings management are adopted to examine the research hypotheses.

Findings
The authors find that the disclosure management solution (DMS) XBRL implementation is positively associated with earnings release efficiency for companies with good news. The authors also find that DMS implementation strategy is negatively related to accruals-based earnings management, but positively related to real activities-based earnings management measured by abnormal cash flows.

Research limitations/implications
The results of this study can inform regulators, investors and corporate management on how XBRL adoption is associated with corporate financial reporting.

Originality/value
The study contributes to the XBRL literature by providing empirical evidence on how the strategies adopted by companies to implement XBRL may affect the results of XBRL mandatory adoption.
The use of chicken feather fibers as filling material in Winter clothes for heat insulation purposes
Authors: Pasayev Nazim , Tekoglu Onur 
Published: February 2019

Purpose
The purpose of this paper is to investigate if the fibers obtained from chicken feathers have a possibility to be used or not used in Winter outerwears as a filling material in terms of thermal insulation parameters.

Design/methodology/approach
In the study, thermal properties of the heat-resistant interlining samples produced from the chicken feathers fibers were analyzed in comparison with the samples produced from the industrial filling materials.

Findings
In the study, it was revealed that the use of chicken feathers fibers as filling material in Winter outerwears was possible.

Practical implications
The use of chicken feather fibers in Winter outerwears as a filling material will be an extremely low-cost alternative to pile flies of water birds which are sufficiently expensive filling materials.

Social implications
A significant portion of the chicken feather, which is released as a by-product in the production of chicken meat, is destroyed as industrial waste by digging or burning. Some of this product is used in the production of such cheap products as poultry feed. In the case of the production of fibers from the chicken feather, the use of these fibers as a filler in Winter clothing along with environmental protection will allow the use of this product for the production of products of higher cost.

Originality/value
The use of feathers’ material as a filling material in Winter outerwears has been known since ancient times. Due to the rough structure and low elasticity of chicken feathers, chicken feathers are not the best raw material for this purpose. This study revealed that it is possible to use chicken feathers as a filling material in terms of heat protection. The study is original in this respect.
“I like computers. I hate coding”: a portrait of two teens’ experiences
Authors: Haduong Paulina 
Published: February 2019

Purpose
Some empirical evidence suggests that historically marginalized young people may enter introductory programming experiences with skepticism or reluctance, because of negative perceptions of the computing field. This paper aims to explore how learner identity and motivation can affect their experiences in an introductory computer science (CS) experience, particularly for young people who have some prior experience with computing. In this program, learners were asked to develop digital media artifacts about civic issues using Scratch, a block-based programming language.

Design/methodology/approach
Through participant observation as a teacher and designer of the course, artifact analysis of student-generated computer programs and design journals, as well as with two follow-up 1-h interviews, the author used the qualitative method of portraiture to examine how two reluctant learners experienced a six-week introductory CS program.

Findings
These learners’ experiences illuminate the ways in which identity, community and competence can play a role in supporting learner motivation in CS education experiences.

Research limitations/implications
As more students have multiple introductory computing encounters, educators need to take into account not only their perceptions of the computing field more broadly but also specific prior encounters with programming. Because of the chosen research approach, the research results may lack generalizability. Researchers are encouraged to explore other contexts and examples further.

Practical implications
This portrait highlights the need for researchers and educators to take into account student motivation in the design of learning environments.

Originality/value
This portrait offers a novel examination of novice programmer experiences through the choice in method, as well as new examples of how learner identity can affect student motivation.

Published: February 2019

Purpose
The purpose of this paper is to examine publication characteristics and dynamic evolution of the Industrial Management & Data Systems (IMDS) over the past 25 years from volume 94, issue 1, in 1994 through volume 118, issue 9, in 2018, using a bibliometric analysis, and identify the leading trends that have affected the journal during this time frame.

Design/methodology/approach
A bibliometric approach was used to provide a basic overview of the IMDS, including distribution of publication and citations, articles citing the IMDS, top-cited papers and publication patterns. Then, a complex network analysis was employed to present the most productive, influential and active authors, institutes and countries/regions. In addition, cluster analysis and alluvial diagram were used to analyze author keywords.

Findings
This study presents the basic bibliometric results for the IMDS and focuses on exploring its performance over the last 25 years. And it reveals the most productive, influential and active authors, institutes and countries/regions in IMDS. Moreover, this study detects the existence of at least five different keywords clusters and discovers how themes have evolved through the intricate citation relationships in IMDS.

Originality/value
The main contribution of this paper is the use of multiple analysis techniques from a complex network paradigm to emphasize the time evolving nature of the co-occurrence networks and to explore the variation of the collaboration networks in the IMDS. For the first time, the evolution of research themes is revealed with a purely data-driven approach.

ObjectiveTo perform a factor analysis of the Practice Integration Profile (PIP), a 30‐item practice‐level measure of primary care and behavioral health integration derived from the Agency for Healthcare Research and Quality's Lexicon for Behavioral Health and Primary Care Integration.Data SourcesThe PIP was completed by 735 individuals, representing 357 practices across the United States.Study DesignThe study design was a cross‐sectional survey. An exploratory factor analysis and assessment of internal consistency reliability via Cronbach's alpha were performed.Data Collection MethodsParticipant responses were collected using REDCap, a secure, web‐based data capture tool.Principal FindingsFive of the PIP's six domains had factor loadings for most items related to each factor representing the PIP of 0.50 or greater. However, one factor had items from two PIP domains that had loadings >0.50. A five‐factor model with redistributed items resulted in improved factor loadings for all domains along with greater internal consistency reliability (>0.80).ConclusionsFive of the PIP's six domains demonstrated excellent internal consistency for measures of health care resources. Although minor improvements to strengthen the PIP are possible, it is a valid and reliable measure of the integration of primary care and behavioral health.

Published: February 2019

AbstractAn investigation of the naturally occurring aluminum contents in grains, fruits and vegetables locally planted in some areas of China was conducted, and the aluminum dietary intake from the investigated food was estimated. A total of 2,469 samples were collected during 2013 to 2014 and tested for aluminum content using ICP‐MS method. The results showed that although 77.6% of the samples contained aluminum less than 5 mg/kg, significant variations of aluminum contents were observed in different food groups. Generally, the aluminum contents were found to be relatively high in dried grains and fresh vegetables, and low in fresh fruits. The mean value of aluminum contents in grains was 6.3 mg/kg, with wheat being the highest, followed by soybean and corn. The fresh vegetables had an average aluminum content of 4.7 mg/kg, with leafy vegetables being the highest, followed by bulb and stem vegetables. Most varieties of fresh fruits were low in aluminum, with the mean of 1.3 mg/kg. Based on the food consumption data from the China National Nutrient and Health Survey, the average weekly dietary intake of naturally occurring aluminum from the investigated foods was estimated to be 0.62 mg/kg bw for the general population and 0.55 to 1.00 mg/kg bw for different age groups. Grains and vegetables were the main contributors to the overall intake. Evaluated against the provisional tolerable weekly intake (PTWI) of 2 mg/kg bw, the dietary naturally occurring aluminum intake from the investigated foods was considered to be no safety concern.

Published: February 2019

AbstractAcid adaptation in Salmonella Enteritidis was characterized by phenotypic and gene‐expression analyses. S. Enteritidis cells at log‐phase and stationary‐phase were kept at pH 4.5 to 6.0 for 1 to 4 hours. All treatments induced various levels of acid tolerance response that were dependent on pH, exposure time and growth phase. This acid adaptation resulted in tolerance to 50 °C and 8% NaCl regardless of the growth phase. However, the tolerance of log‐phase and stationary‐phase cells to low temperatures (4 and –20 °C) was increased and decreased, respectively. RT‐qPCR analysis revealed that genes involved in tolerance to acid (SEN1564A and cfa), heat (rpoH, uspB, and htrA), salt (proP, proV, and osmW), and cold (cspA, cspC, and csdA) stress were generally upregulated after acid adaptation. These results provide an initial insight into mechanisms of acid adaptation and induced cross protection in S. Enteritidis.Practical ApplicationStress tolerance acquisition resulting from acid adaptation in foodborne pathogens poses a great threat to food safety. The current work showed that acid adaptation induced direct tolerance and cross‐tolerance to high temperature, low temperature, and salt in Salmonella Enteritidis, possibly due to the upregulation of stress tolerance‐related genes. These results provide key insights into acid adaptation mechanisms and efficient control of S. Enteritidis.
Effects of vitamin D on disease activity and serum interleukin‐6 in rheumatoid arthritis
Authors: Gopal Kumutha , Thevarajah Malathi , Ng Choung Min , Raja Jasmin 
Published: February 2019

AbstractAimVitamin D3 or 25(OH)D3 may have a potential role in rheumatoid arthritis (RA) pathogenesis by inhibiting the expression of pro‐inflammatory cytokines including interleukin‐6 (IL‐6). The aim of this study is to determine the clinical factors of vitamin D deficiency in multi‐ethnic Malaysian RA patients and its association with disease activity, functional disability and serum IL‐6 levels.MethodOne hundred RA patients and 50 healthy controls, sex‐ and age‐matched, were recruited. Disease Activity Score of 28 joints and Health Assessment Questionnaire scores were assessed. Baseline serum 25(OH)D3 and IL‐6 were measured in all subjects. RA patients who were vitamin D deficient were given loading doses of vitamin D3 and repeated assessments were done.ResultsVitamin D deficiency (<50 nmol/L) was found in 63% of RA patients and 76% of healthy controls. Chinese RA patients and healthy controls had significantly more sufficient 25(OH)D3 levels compared to Malays and Indians (P < 0.001). Serum 25(OH)D3 level was still negatively associated with body mass index in RA patients (P = 0.002) after adjustment for potential confounding variables. No significant association was seen between 25(OH)D3 levels and disease activity or serum IL‐6 levels in both pre‐ and post‐treatment groups. A negative association was observed between serum 25(OH)D3 and functional disability, including a 33% improvement post‐treatment (mean ± SD: 0.30 ± 0.46 to 0.20 ± 0.18).ConclusionVitamin D deficiency is prevalent in Malaysian RA patients. This study suggests that vitamin D is not associated with disease activity or serum IL‐6 levels but it may have a role in functional disability in RA patients.
Characterization and expression analysis of KIT and MITF‐M genes in llamas and their relation to white coat color

Published: February 2019

SummaryThe llama (Lama glama) is a fiber‐producing species that presents a wide range of coat colors, among which white is one of the most important for the textile industry. However, there is little information about the molecular mechanisms that control the white phenotype in this species. In domestic mammals, a white coat is usually produced by mutations in the KIT proto‐oncogene receptor tyrosine kinase (KIT) and microphthalmia‐associated transcription factor (MITF) genes. In this work we have sequenced and described the coding regions of KIT and MITF‐M, the melanocyte‐specific isoform, and the two transcriptional variants MITF‐M(−) and MITF‐M(+). Moreover, we studied the expression of these genes in the skin of white and colored llamas. Although no variants were revealed to be associated with white coat color, significant differences between phenotypes were observed in the expression levels of KIT and MITF‐M. Interestingly, white llamas expressed less MITF‐M(+) than did colored ones, which is consistent with a consequent reduction in the synthesis of melanin. Even though our results indicate that downregulation of KIT and MITF‐M expression is involved in white phenotype production in llamas, the causative gene of white coat color remains unknown.
The role of vitamin D receptor gene polymorphisms in the pathogenesis of Behçet's disease: A case‐control study in Turkish population

Published: February 2019

AbstractBackgroundBehçet's
disease (BD) is an inflammatory disorder characterized by oral aphthous lesions, uveitis, and genital ulcerations. The vitamin D receptor (VDR) has a crucial role in the pathogenesis of this disease because it mediates the functions of vitamin D in the immune system. Alterations of VDR expression related to polymorphic alleles of the VDR gene may play a pathogenic role in BD and BD's clinical presentations.Methods150 BD patients and 150 healthy controls were included and genotyping was carried out by polymerase chain reaction/restriction fragment length polymorphism.ResultsSignificant differences between patients and controls in rs1544410, rs2228570, and rs731236 genotypes were observed (respectively, p = 0.04, p = 0.007, p = 0.012). The clinical characteristics of BD patients were evaluated and patients with ocular lesions had a higher percentage of rs1544410 A alleles (p = 0.004), and patients with oral aphthous lesions, a positive pathergy tests, and arthritis had more rs2228570 C alleles than patients without these clinical findings (respectively, p < 0.001, p = 0.021, p = 0.045).ConclusionVDR gene polymorphisms may possibly have a role in the pathogenesis of BD through their effects on VDR expression and may be associated with the increased risk of several clinical findings.

AbstractObjectiveThe aim of this study was to investigate the impact of a diagnostic workshop on undergraduate teaching‐learning process for the diagnosis and management of tooth restorations.MethodsThe first stage of the study was a randomised controlled study with two parallel groups: lecture (L) and lecture coupled with a diagnostic workshop (LW). A pool of cases of tooth restorations including secondary caries and marginal defects was used for training. Theoretical knowledge, perception about the activity and practical abilities were evaluated. The second stage of the study assessed students’ theoretical knowledge retention six months following intervention. All students included in the first stage of the study were exposed to LW. Hence, a new control group of students not exposed to LW was selected. One‐way analysis of variance, Fisher's exact test, Kruskal‐Wallis test and multilevel regression analysis were used as part of statistical analysis.ResultsThe LW group had greater scores for the assignment of lesion severity and activity, presence of marginal defect and treatment indication than the L group (P < 0.05). Multilevel regression analysis showed a positive impact of the workshop diagnosis in the correct assessment of lesion activity (P = 0.03). There was no statistical difference between the LW and L groups in students’ perception of the activity. The LW group showed greater knowledge retention after six months than the L group (P = 0.027).ConclusionLecture coupled with diagnostic workshop improved students’ practical skills of diagnosis restorations and knowledge retention in the six months following intervention.
