PurposeThe purpose of this paper is to analyze the innovation process of organizations representing the main sectors of Brazilian economic activity.Design/methodology/approachThe literature review focuses on analyzing the innovation process characteristics regarding the innovation types. The authors carried out interviews with executives and managers in charge of innovation at the leading large companies in the respective sectors analyzed. The data analysis of this qualitative research was structured in three steps. The first step is the analysis of data collected for encoding, the second step, the summarization of the common points presented by the companies in each sector and, finally, the interpretation of these data, aided by triangulation from secondary data that support the analysis of the collected primary data.FindingsThe main contribution of this study is to characterize the innovation process of organizations representing the main sectors of the Brazilian economy, with a classification regarding the sectoral innovation standard.Practical implicationsThe authors’ intent is that the paper can contribute with a comparative analysis among companies of the same sector and, subsequently, among companies of the different surveyed sectors. Thus, the characterization aims to present the companies’ innovation process and the comparative analysis aims to verify the innovation sectoral patterns. In addition, as implications for management practice, some strategies for better knowledge management in the organization are suggested for each type of innovation.Originality/valueThe main theoretical contribution focuses on the development of a conceptual model that structures the analyzed variables of the constructs “innovation process” and “innovation sectoral patterns”, allowing not only the characterization but also the comparative analysis of the representative organizations present in the sample.
Understanding collaborative tourism information searching to support online travel planning
Authors: Mohammad Arif Abu Shamim , Du Jia Tina 
Published: December 2018

PurposeCollaborative information searching is common for people when planning their group trip. However, little research has explored how tourists collaborate during information search. Existing tourism Web portals or search engines rarely support tourists’ collaborative information search activities. Taking advantage of previous studies of collaborative tourism information search behavior, in the current paper the purpose of this paper is to propose the design of a collaborative search system collaborative tourism information search (ColTIS) to support online information search and travel planning.Design/methodology/approachColTIS was evaluated and compared with Google Talk-embedded Tripadvisor.com through a user study involving 18 pairs of participants. The data included pre- and post-search questionnaires, web search logs and chat history. For quantitative measurement, statistical analysis was performed using SPSS; for log data and the qualitative feedback from participants, the content analysis was employed.FindingsResults suggest that collaborative query formulation, division of search tasks, chatting and results sharing are important means to facilitate tourists’ collaborative search. ColTIS was found to outperform Tripadvisor significantly regarding the ease of use, collaborative support and system usefulness.Originality/valueThe innovation of the study lies in the development of an integrated real-time collaborative tourism information search system with unique features. These features include collaborative query reformulation, travel planner and automatic result and query sharing that assist multiple people search for holiday information together. For system designers and tourism practitioners, implications are provided.
Fostering brand love in Facebook brand pages
Authors: Palazon Mariola , Delgado-Ballester Elena , Sicilia Maria 
Published: December 2018

Purpose
The purpose of this paper is to analyze how brand love is built in the context of brand pages by proposing a model in which brand love depends on relationships ties with other brand consumers (sense of brand community) and with the brand itself (self–brand connection).

Design/methodology/approach
Information was collected from a sample of 559 members of the community of a well-known baby food brand on Facebook. Data were collected through an online questionnaire sent by the company.

Findings
Results suggest that both sense of brand community and self–brand connection foster brand love and that self–brand connection exerts a mediating role between sense of brand community and brand love. Furthermore, the effect of brand community on brand love is conditioned by a personal trait of individuals such as brand engagement in self-concept. In addition, this study identifies a new consequence of brand love not previously analyzed in the literature: brand equity.

Research limitations/implications
A potential shortcoming is the product category analyzed and that the length of membership was not controlled and it may be a moderator between participation and community consequences.

Practical implications
The key implications are the importance of nurturing relationship ties among brand users and building self–brand connections on brand pages as precursors of brand love.

Originality/value
The study offers empirical evidence about the mechanism through which brand love is formed on social-media platforms such as Facebook. Furthermore, the authors have demonstrated the relationship between brand love and brand equity, which had not been examined yet in the literature.
Human resources disclosure: an exploratory study of the quality in Qatar
Authors: Alawi Nahg Abdulmajid , Belfaqih Husam Mohammed 
Published: December 2018

Purpose
The purpose of this paper is to determine the quality of HR disclosure of companies listed in Qatari Exchange Market and identify factors that influence the level of this HR disclosure quality.

Design/methodology/approach
Content analysis of annual reports and sustainability reports of 12 companies from industrial and real estate sectors over the period 2013–2015 had been analyzed using the three-point scale (0–2, numerical disclosure 2, 1 for narrative form and 0 for not disclosed). This research employed also multiple regressions, in order to examine the impact of profitability and employee expenses on HR disclosure quality.

Findings
The results point out that HR disclosure quality level is very low among the sample companies. The ordinary least squares (OLS) regression analysis results indicate that the level of HR disclosure quality is associated with company’s employees expenses as a proportion of its total operating expenses, whereas profitability does not have a significant influence on its level of HR disclosure quality.

Research limitations/implications
The current study has two important limitations. First, the sample of the study consists of only 12 leading Qatari industrial and real estate sectors firms listed on the Qatar Stock Exchange Market. Second, the study used an unweighted index which implies equal importance of the selected information items.

Originality/value
The study has bridged the literature gaps by offering empirical evidence and new insights on the HR disclosure quality in Qatar and the factors that affect, which have not been examined before.
Your infections are what you eat: How host ecology shapes the helminth parasite communities of lizards
Authors: Leung Tommy L. F. , Koprivnikar Janet 
Published: December 2018

Abstract

Understanding how parasite communities are assembled, and the factors that influence their richness, can improve our knowledge of parasite–host interactions and help to predict the spread of infectious diseases. Previous comparative analyses have found significant influences of host ecology and life history, but focused on a few select host taxa.

Host diet and habitat use play key roles in the acquisition of parasitic helminths as many are trophically transmitted, making these attributes potentially key indicators of infection risk. Given the paucity of comparative studies with non‐piscine, non‐avian or non‐mammalian hosts, it is critical to examine the degree to which host ecology influences parasite communities in other host taxa in order to identify common drivers.

We examined helminth diversity in over 350 species of lizards in relation to their body mass, ecology (diet and habitat use) and life history (clutch size, and ovo‐ or viviparity) using previously published data.

Overall, lizard species with herbivorous diets harboured fewer types of helminths (especially larval stages), with similar results for traits that were ultimately strongly associated with diet (host mass and habitat use). Large hosts tended to be herbivores with few helminth types, whereas species utilizing arboreal habitats typically consumed some animal matter and hosted more helminths.

Understanding how host ecology and life history are related to their parasite assemblages has significant implications for the risk of acquiring novel parasites. Our results indicate an overwhelming influence of host diet such that many helminths may be relatively easily acquired by hosts in new ranges, or through dietary shifts.

SummaryChytrids are ubiquitous fungal parasites in aquatic ecosystems, infecting representatives of all major phytoplankton groups. They repack carbon from inedible phytoplankton hosts into easily ingested chytrid propagules (zoospores), rendering this carbon accessible to zooplankton. Grazing on zoospores may circumvent bottlenecks in carbon transfer imposed by the dominance of inedible or poorly nutritious phytoplankton (mycoloop). We explored qualitative aspects of the mycoloop by analysing lipid profiles (fatty acids, sterols) of two chytrids infecting two major bloom‐forming phytoplankton taxa of contrasting nutritional value: the diatom Asterionella formosa and the filamentous cyanobacterium Planktothrix agardhii. The polyunsaturated fatty acid composition of chytrids largely reflected that of their hosts, highlighting their role as conveyors of otherwise inaccessible essential lipids to higher trophic levels. We also showed that chytrids are capable of synthesizing sterols, thus providing a source of these essential nutrients for grazers even when sterols are absent in their phytoplankton hosts. Our findings reveal novel qualitative facets of the mycoloop, showing that parasitic chytrids, in addition to making carbon and essential lipids available from inedible sources, also upgrade their host's biochemical composition by producing sterols de novo, thereby enhancing carbon and energy fluxes in aquatic food webs.

ObjectiveTo evaluate the cost‐effectiveness of incisional negative pressure wound therapy (iNPWT) in preventing surgical site infection in obese women after caesarean section.DesignA cost‐effectiveness analysis conducted alongside a clinical trial.SettingFive obstetric departments in Denmark.PopulationWomen with a pregestational body mass index (BMI) ≥30 kg/m2.MethodWe used data from a randomised controlled trial of 876 obese women who underwent elective or emergency caesarean section and were subsequently treated with iNPWT (n = 432) or a standard dressing (n = 444). Costs were estimated using data from four Danish National Databases and analysed from a healthcare perspective with a time horizon of 3 months after birth.Main outcome measuresCost‐effectiveness based on incremental cost per surgical site infection avoided and per quality‐adjusted life‐year (QALY) gained.ResultsThe total healthcare costs per woman were €5793.60 for iNPWT and €5840.89 for standard dressings. Incisional NPWT was the dominant strategy because it was both less expensive and more effective; however, no statistically significant difference was found for costs or QALYs. At a willingness‐to‐pay threshold of €30,000, the probability of the intervention being cost‐effective was 92.8%. A subgroup analysis stratifying by BMI shows that the cost saving of the intervention was mainly driven by the benefit to women with a pre‐pregnancy BMI ≥35 kg/m2.ConclusionIncisional NPWT appears to be cost saving compared with standard dressings but this finding is not statistically significant. The cost savings were primarily found in women with a pre‐pregnancy BMI ≥35 kg/m2.Tweetable abstractProphylactic incisional NPWT reduces the risk of SSI after caesarean section and is probably dominant compared with standard dressings #healtheconomics.

Authors: Berlingo L , Girault A , Azria E , Goffinet F , Le Ray C 
Published: December 2018

ObjectiveTo examine the relationship between gender and a career in academic medicine.DesignMixed‐methods study.SettingObstetrics–gynaecology postgraduate training programme in Paris, France.SamplePostgraduate trainees in obstetrics–gynaecology (n = 204).MethodsStatistical analysis of quantitative survey data, thematic analysis of qualitative interview data and integrative analysis.Main outcome measuresWomen's aspirations and obstacles related to their decision about a career in academic medicine.ResultsA career in academic medicine was envisaged by 13% of the women residents and 27% of the men (P = 0.01). Women reported receiving advice from a mentor less often than men (38.8% versus 52.9%, P = 0.002). Overall, 40.6% of women and 2.9% of men reported experiencing gender discrimination (P < 0.001). In response to the question ‘Do you have doubts about your ability to pursue or succeed at an academic career?’, 62.4% of the women and only 17.7% of the men answered yes (P < 0.001). The global analysis identified the following obstacles: persistent gender stereotypes that produce everyday sexism, lack of identification with male role models, lack of mentors, perceived discrimination, an ideal of professional excellence that is difficult to attain, constraining professional organisational norms, inequality between men and women in the domestic and family spheres, and finally self‐censorship and important doubts about their ability to combine a demanding career and a fulfilling personal life.ConclusionsWomen reported the desire to follow a career in academic medicine half as often as men. Improving the presence and visibility of role models for residents and combating workplace discrimination will address some of the barriers to women choosing a career in academic medicine.Tweetable abstractWomen obstetric trainees in France are only half as likely as men to envisage following an academic path.
“Are you accepting new patients?” A pilot field experiment on telephone‐based gatekeeping and Black patients’ access to pediatric care
Authors: Leech Tamara G.J. , Irby‐Shasanmi Amy , Mitchell Anne L. 
Published: December 2018

Study ObjectivesTo determine whether name and accent cues that the caller is Black shape physician offices’ responses to telephone‐based requests for well‐child visits.Method and DataIn this pilot study, we employed a quasi‐experimental audit design and examined a stratified national sample of pediatric and family practice offices. Our final data include information from 205 audits (410 completed phone calls). Qualitative data were blind‐coded into binary variables. Our case‐control comparisons using McNemar's tests focused on acceptance of patients, withholding information, shaping conversations, and misattributions.FindingsCompared to the control group, “Black” auditors were less likely to be told an office was accepting new patients and were more likely to experience both withholding behaviors and misattributions about public insurance. The strength of associations varied according to whether the cue was based on name or accent. Additionally, the likelihood and ways office personnel communicated that they were not accepting patients varied by region.ConclusionsLinguistic profiling over the telephone is an aspect of structural racism that should be further studied and perhaps integrated into efforts to promote equitable access to care. Future research should look reactions to both name and accent, taking practice characteristics and regional differences into consideration.
Increased Hematocrit Due to Electrical‐Waveform Exposures in Splenectomized Sus scrofa,
Authors: Jauchem James R. , Burns Jennie M. , Voorhees William B. , Jirjis Michael B. 
Published: December 2018

AbstractIn laboratory studies of the pig Sus scrofa, hematocrit has consistently increased after conducted‐electrical‐weapon (CEW) exposures, possibly due to contraction of the spleen. Splenectomized animals and intact sham control animals were exposed, each for 30 sec, to a benchtop‐produced electrical waveform of net charge levels similar to those of some CEWs. Changes in the blood were compared statistically. Hematocrit increased significantly in both splenectomized and sham animals. There were no significant main‐effect differences between values of hematocrit from the two groups. There were, however, significant interactive effects of time and splenectomy for hematocrit, red blood cell count, and hemoglobin. After peak values were reached for these variables, values returned toward baseline levels more slowly in splenectomized animals. This may have been due to the lack of a spleen to sequester red blood cells (thereby resulting in more cells remaining in the general circulation), unlike sham animals with intact spleens.
When to use next generation sequencing or diagnostic PCR in diet analyses
Authors: Rennstam Rubbmark Oskar , Sint Daniela , Cupic Sandra , Traugott Michael 
Published: December 2018

AbstractNext‐generation sequencing (NGS) is increasingly used for diet analyses; however, it may not always describe diet samples well. A reason for this is that diet samples contain mixtures of food DNA in different amounts as well as consumer DNA which can reduce the food DNA characterized. Because of this, detections will depend on the relative amount and identity of each type of DNA. For such samples, diagnostic PCR will most likely give more reliable results, as detection probability is only marginally dependent on other copresent DNA. We investigated the reliability of each method to test (a) whether predatory beetle regurgitates, supposed to be low in consumer DNA, allow to retrieve prey sequences using general barcoding primers that co‐amplify the consumer DNA, and (b) to assess the sequencing depth or replication needed for NGS and diagnostic PCR to give stable results. When consumer DNA is co‐amplified, NGS is better suited to discover the range of possible prey, than for comparing co‐occurrences of diet species between samples, as retested samples were repeatedly different in prey detections with this approach. This shows that samples were incompletely described, as prey detected by diagnostic PCR frequently were missed by NGS. As the sequencing depth needed to reliably describe the diet in such samples becomes very high, the cost‐efficiency and reliability of diagnostic PCR make diagnostic PCR better suited for testing large sample‐sets. Especially if the targeted prey taxa are thought to be of ecological importance, as diagnostic PCR gave more nested and consistent results in repeated testing of the same sample.

BackgroundPulmonary emphysema is a major component of chronic obstructive pulmonary disease and lung cancer. However the prognostic significance of quantitative emphysema severity in patients with lung cancer is unclear. We analyzed whether numerical emphysema value is a prognostic factor for recurrence in patients with surgically resected non‐small cell lung cancer.MethodsWe quantified emphysema severity of the whole lung and regional lobes in 45 patients (mean age 68.0 years) using an automated chest computed tomography‐based program. Predictive factors for recurrence were investigated using a Cox proportional hazards model. Recurrence‐free and overall survival was compared after dichotomization of patients according to whole lung emphysema severity.ResultsThe mean percentage emphysema ratio of the whole lung was 1.21 ± 2.04. Regional lobar emphysema severity was highest in the right middle lobe (1.93 ± 0.36), followed by right upper (1.35 ± 2.50), left upper (1.34 ± 2.12), left lower (1.05 ± 2.52), and right lower (0.78 ± 2.28) lobes. The low severity group showed significantly longer overall survival compared to the high severity group (log‐rank test, P = 0.018). Quantitative emphysema severity of the whole lung (hazard ratio 1.36; 95% confidence interval 1.0–1.73) and stage III (hazard ratio 6.17; 95% confidence interval 1.52–25.0) were independent predictors of recurrence after adjusting for age, gender, smoking status, and forced expiratory volume in one second.ConclusionThe severity of whole lung emphysema was independently associated with recurrence. Patients with non‐small cell lung cancer and marginal pulmonary emphysema at lower severity survive longer after curative‐intent surgery.
Treatment of catatonia in autism spectrum disorders
Authors: Wachtel L. E. 
Published: December 2018

ObjectiveTo review the treatment courses of 22 autistic patients diagnosed with catatonia over a 12‐year period, including treatment with benzodiazepines and electroconvulsive therapy.MethodRetrospective review of inpatient and outpatient records of 22 autistic youth presenting to a neurobehavioral service who were treated for catatonia.ResultsSix girls and 16 boys ranging from ages 8 to 26 years old presenting for neurobehavioral assessment were found to meet criteria for catatonia according to the DSM5 and were treated for such. All but one patient was initially unsuccessfully treated with benzodiazepines in dosages ranging from 1 to 27 mg daily, and all patients underwent electroconvulsive therapy. Mean age of ECT start was 15.6 years old, and the total number of ECT received ranged from 16 to 688, with 13 patients still receiving maintenance ECT at the end of the study period. ECT conferred prominent patient benefit in terms of catatonic symptom reduction, including alleviation of incapacitating, treatment‐resistant self‐injury.ConclusionMyriad symptoms of catatonia were seen in this sample of 22 autistic youth. Implementation of anti‐catatonic paradigms, particularly electroconvulsive therapy, conferred vast patient benefit.
