    While a significant amount of research has identified individual founder traits and perceptions that significantly affect startup trajectory, relatively little work has investigated the interactions between these variables. Specifically, while prior research has shown that psychological safety, entrepreneurial self-efficacy, and entrepreneurial bricolage skills are correlated with firm performance, the linkages between these variables is unknown. The purpose of this study was to investigate the relationship between these variables leveraging data from 71 startup founders. Results suggest that team psychological safety and entrepreneurial self-efficacy can individually predict entrepreneurial bricolage, with the combination of the two yielding a stronger predictive relationship. Finally, findings suggest that psychological safety, entrepreneurial self-efficacy, and entrepreneurial bricolage are not correlated with firm performance, contradicting prior findings

    Identifying key factors of engineering innovativenessSignificant resources are spent nationally and locally to foster innovation, yet limited research exists onthe personal characteristics of innovators, especially those found in engineering. This three-yearcollaborative research project, currently in its second year, has led to the identification of specificattributes associated with engineering innovators, with the potential to inform a broad range of people,from engineering students to engineering educators to practicing engineers and their managers. Throughthis project, we have developed a socially constructed set of key engineering innovativenesscharacteristics based on the views of a diverse group of engineering innovation experts. We have alsodetermined which characteristics are more important in specific stages of the innovation process, andexamined the innovativeness factors that are innate/fixed (e.g., cognitive style) versus those that can bechanged/enhanced (e.g., knowledge, skills).Through a series of interviews and a Delphi study with engineering innovators from academia andindustry, we found the innovation process to have at least three distinct stages: (1) the front-end ordiscovery stage, (2) the middle or development stage, and (3) the back-end or implementation andadoption stage. For example, some of the key characteristics of engineering innovativeness that wereidentified with the discovery stage of the innovation process included: experimenter, alternatives seeker,curious, risk taker, and visionary. Future research steps will focus on testing and widely disseminating avalidated instrument that assesses the key engineering innovativeness characteristics, and using ourresearch results to inform the education of innovative engineers and the professional development ofengineering practitioners

    BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

    Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

    Design Practica as Authentic Assessments in First-year Engineering Design Courses

    This paper describes the design and evaluation of a novel assessment for first-year engineering design courses that is rooted in an authentic design challenge. This approach modifies the traditional written-exam approach typically found in engineering courses, which is inherently inauthentic and cannot easily capture the exploratory nature of engineering design. Our assessment improves alignment with common learning objectives found in first-year engineering design courses and additionally prepares students for the type of case study interviews that are increasingly common for entry-level engineering jobs. To evaluate our assessment, 50 first-year students completed the engineering design self-efficacy instrument once before beginning the assessment and a second time approximately 48 hours later upon completion of a reflection assignment. In addition, students retrospectively reported their perceived change in self-efficacy during the assessment. Analysis shows that students perceived a large retrospective increase in skill level, despite only a small increase in directly measured self-efficacy. These results are analyzed in light of the Dunning-Kruger effect and we posit that the assessment helps to align students’ self-efficacy with their actual skill level. Increased alignment of self-efficacy with skill level may minimize student frustration when encountering challenging tasks in the future, potentially increasing retention of engineering students as well as facilitating the development of lifelong learning attitudes

    "Thus, I had to go with what I had": A Multiple Methods Exploration of Novice Designers' Articulation of Prototyping Decisions

    Effectively communicating designs to stakeholders or end users is a critical step in the design process yet can be a difficult challenge for engineers. Prototypes are unique tools that can enhance communication between these two groups, as prototypes are physical manifestations of the designer’s mental model. Previous work has demonstrated that novice designers often struggle to use prototypes as communication tools. We argue that it is critical that engineering students learn to fully leverage prototypes, and thus the current work sought to understand the relationship between argumentation, prototyping, and design decisions. In order to understand the communication patterns of novice designers during a prototyping task, a controlled study was conducted with a total of 46 undergraduate engineering students. The analysis of quantitative and qualitative data point to the intricate linkages between how students make material decisions and how they justify those decisions

    Using workplace thriving theory to investigate first-year engineering students\u27 abilities to thrive during the transition to online learning due to COVID-19

    Background During the onset of the COVID-19 crisis, universities rapidly pivoted to online formats and were often unable to adhere to the best practices of online learning highlighted in prior literature. It is well documented that a variety of barriers impeded “normal” educational practices. Purpose/Hypothesis The purpose of this paper is to investigate the perceptions of first-year engineering students enrolled in an introductory engineering design course during the rapid transition to online working environments. We view students\u27 perceptions through the theoretical lens of workplace thriving theory, a framework that allowed us to capture aspects of education required for students to thrive in non-optimum learning settings. Design/Method This research employed semi-structured interview methods with 13 students enrolled in an introductory engineering design course that relies on project-based team learning. We analyzed interview transcripts using thematic analysis through an abductive approach and made interpretations through workplace thriving theory. Results Results indicated that students\u27 abilities to thrive are related to four intersecting themes that demonstrate how workplace thriving theory manifests in this unanticipated online setting. These themes demonstrate elements that must be optimized for students to thrive in settings such as this: relationships with others, building and sharing knowledge through interactions, perceptions of experiential learning, and individual behaviors. Conclusion Our research, viewed through workplace thriving theory, highlights the mechanisms by which students tried to succeed in suboptimal environments. While not all our participants showed evidence of thriving, the factors required for thriving point to opportunities to harness these same factors in in-person instruction environments
