The purpose of this research was to understand perceptions and experiences of inclusion among underrepresented early-career biomedical researchers (postdoctoral fellows and early-career faculty) enrolled in the Building Up study. Because inclusion is vital to job satisfaction and engagement, our goal was to shed light on aspects of and barriers to inclusion within the academic workforce.
Methods:
We used qualitative interviews to assess workplace experiences of 25 underrepresented postdoctoral fellows and early-career faculty including: their daily work experiences; sense of the workplace culture within the institutions; experiences with microaggressions, racism, and discrimination; and whether the diversity, equity, and inclusion (DEI) policies and practices at their institution enhanced their experiences. Using qualitative methods, we identified themes that highlighted high-level characteristics of inclusion.
Results:
Four distinct themes were identified: (1) participants appreciated the flexibility, versatility, and sense of fulfillment of their positions which enhanced feelings of inclusion; (2) greater psychological safety led to a greater sense of belonging to a research community; (3) participants had varied experiences of inclusion in the presence of microaggressions, racism, and discrimination; and (4) access to opportunities and resources increased feelings of value within the workplace.
Discussion:
Our findings provide new insight into how inclusion is experienced within the institution among underrepresented early-career biomedical researchers. This research points to specific approaches that could be used to enhance experiences of inclusion and to address barriers. More research is needed to understand how to accomplish a balance between the two, so that perceptions of inclusion outweigh negative experiences.
Clinical research professionals (CRPs) are integral to the academic medical center workforce, research operations, and daily clinical research tasks; however, due to inconsistent training, there is a shortage of qualified CRPs. The Joint Task Force for Clinical Trial Competency created a competency framework for CRPs, which has demonstrated positive results from various institutions, but training programs have been limited in standardization, replicability, and dissemination. To improve this, we designed the University of Texas Southwestern (UTSW) Medical Center Clinical Research Foundations (CRF) training program, which is a competency-based online self-paced CRP training curriculum hosted via the Collaborative Institutional Training Initiative (CITI) portal. We examined feasibility, acceptability, and uptake of the UTSW CRF training on an institutional scale and were pleased to find this curriculum is not only feasible but has high levels of acceptability. Furthermore, faculty, clinicians, and trainees voluntarily completed this training program indicating utility across diverse groups. The UTSW CRF combines the existing CITI training modules with UTSW-created material, providing an optimal balance between generalized clinical research education and institutionally tailored content. We believe the UTSW CRF curriculum could serve as a plug-and-play foundational model for other research centers to tailor according to their audience and institutional needs.
To evaluate the influence of pre-existing maternal diabetes mellitus on fetal myocardial performance index and systolic-to-diastolic duration ratio.
Methods:
Prospective cohort study included 179 pregnant women between 20 and 36w6d, divided into 3 groups: Group 1 (120, normal), Group 2 (31, type 1 diabetes mellitus), and Group 3 (28, type 2 diabetes mellitus). Systolic-to-diastolic duration ratio was calculated as the sum of isovolumic contraction time and ejection time divided by the sum of isovolumic relaxation time and ventricular filling time. Spectral Doppler was used to assess left ventricle systolic-to-diastolic duration ratio. Tissue Doppler was used to assess right ventricular filling time. Using spectral Doppler, left ventricle myocardial performance index was calculated as the sum of isovolumic contraction time and isovolumic relaxation time divided by ejection time.
Results:
Pre-existing maternal diabetes mellitus had a significant influence on fasting glucose levels (p < 0.001), left ventricle isovolumic contraction time (p < 0.001), left ventricle ejection time (p = 0.025), and left ventricle myocardial performance index (p < 0.001). Group 2 had higher left ventricle isovolumic contraction time (0.036 vs. 0.031 sec, p = 0.001) and left ventricle myocardial performance index (0.487 vs. 0.453, p = 0.003) compared with Group 1. Group 3 showed higher left ventricle myocardial performance index (0.492 vs. 0.449, p = 0.006) and lower left ventricle ejection time (0.161 vs. 0.169 sec, p = 0.038) than Group 1. Left ventricle systolic-to-diastolic duration (p = 0.704), right ventricle systolic-to-diastolic duration ratio’ (p = 0.757), left ventricle isovolumic contraction time (p = 0.163), left ventricle ejection time (p = 0.093), and left ventricle myocardial performance index (p = 0.087) were not useful parameters in predicting composite neonatal outcomes.
Conclusion:
Pre-existing maternal diabetes mellitus had significant influence on fetal left ventricle myocardial performance index, but no effect on systolic-to-diastolic duration ratio. Systolic-to-diastolic duration ratio was not useful in predicting adverse perinatal outcomes.
Nosemosis, caused by microsporidian parasites of the genus Nosema, is considered a significant health concern for insect pollinators, including the economically important honeybee (Apis mellifera). Despite its acknowledged importance, the impact of this disease on honeybee survivorship remains unclear. Here, a standard laboratory cage trial was used to compare mortality rates between healthy and Nosema-infected honeybees. Additionally, a systematic review and meta-analysis of existing literature were conducted to explore how nosemosis contributes to increased mortality in honeybees tested under standard conditions. The review and meta-analysis included 50 studies that reported relevant experiments involving healthy and Nosema-infected individuals. Studies lacking survivorship curves or information on potential moderators, such as spore inoculation dose, age of inoculated bees, or factors that may impact energy expenditure, were excluded. Both the experimental results and meta-analysis revealed a consistent, robust effect of infection, indicating a threefold increase in mortality among the infected group of honeybee workers (hazard ratio for infected individuals = 3.16 [1.97–5.07] and 2.99 [2.36–3.79] in the experiment and meta-analysis, respectively). However, the meta-analysis also indicated high heterogeneity in the effect magnitude, which was not explained by our moderators. Furthermore, there was a serious risk of bias within studies and potential publication bias across studies. The findings underscore knowledge gaps in the literature. It is stressed that laboratory cage trials should be viewed as an initial step in evaluating the impact of Nosema on mortality and that complementary field and apiary studies are essential for identifying effective treatments to preserve honeybee populations.
ADP-ribosyltransferases of the PARP family encompass a group of enzymes with variegated regulatory functions in cells, ranging from DNA damage repair to the control of cell-cycle progression and immune response. Over the years, this knowledge has led to the use of PARP1/2 inhibitors as mainstay pharmaceutical strategies for the treatment of ovarian, pancreatic, prostate and breast cancers, holding mutations in genes encoding for proteins involved in the DNA repair mechanisms (synthetic lethality). Meanwhile, the last decade has witnessed significant progress in comprehending cellular pathways regulated by mono-ADP-ribosylation, with a huge effort in the development of novel selective compounds to inhibit those PARPs endowed with mono-ADP-ribosylation activity. This review focuses on the progress achieved in the cancer field, delving into most recent findings regarding the role of a subset of enzymes – the interferon-stimulated PARPs – in cancer progression.
Researchers from underrepresented groups leave research positions at a disproportionate rate. We aim to identify factors associated with self-efficacy in career advancement and career commitment among underrepresented post-doctoral fellows and early-career faculty.
Methods:
Building Up is a cluster-randomized trial with 25 academic health institutions. In September-October 2020, 219 Building Up participants completed the pre-intervention assessment, which included questions on demographics, science identity, mentoring, self-efficacy in career advancement (i.e., advancement is open to me, confidence in career progression, confidence in overcoming professional barriers), and career commitment (i.e., intent to continue research training or studying in a field related to biomedical sciences). Using logistic and multinomial logistic regression, we identified characteristics independently associated with self-efficacy in career advancement and career commitment.
Results:
The cohort is 80% female, 33% non-Hispanic/Latinx Black, and 34% Hispanic/Latinx. Having mentors that address diversity was significantly associated with the belief that advancement is open to them (OR = 1.7). Higher science identity (OR = 4.0) and having mentors that foster independence (OR = 1.8) were significantly associated with confidence in career progression. Higher science identity was also significantly associated with confidence in overcoming professional barriers (OR = 2.3) and intent to continue studying in a field related to biomedical sciences (OR = 3.3). Higher age (OR = 2.3) and higher science identity (OR = 4.2) were significantly associated with intent to continue research training.
Discussion:
Science identity and mentoring play key roles in self-efficacy in career advancement and career commitment. These factors may contribute to retention of underrepresented early-career biomedical researchers.
The objective of this chapter is to offer a framework for understanding the debates around the bioeconomy. Indeed, a large body of literature has been developed in an attempt to identify the visions of the future and the narratives that aim to define the bioeconomy. This chapter offers a mapping of these visions and, based on three emblematic cases, shows how the three visions of the bioeconomy relate to economic realities.
Our objective in this chapter is to elaborate on the concepts of transition and paradigm shift and further discuss the concept of sustainability transition. We applied the transition theory proposed by Geels (2010) to the case of bioeconomy. This theory proposes a multi-level perspective for framing socio-technical sustainability transitions. The chapter identifies dynamics and actors involved in the purposive sustainability transition at a micro (e.g., pilot projects, emerging technologies), meso (e.g., leading sectors and industries), and macro (global social, economic, and environmental drivers) levels.
The objective of this chapter is to present two approaches useful in the study of the formation and dynamics of particular systems in the bioeconomy. Innovation systems have a horizontal perspective to production processes, while value-chains analysis adopts a vertical perspective. The innovation system approach conceptualises the circulation of knowledge within systems and the way in which the institutional environment favours the development of innovation. The value chain approach is interested in the co-creation of value, its circulation in the international division of labour, and the relations between regions in the world.
To understand the roots of the bioeconomy, it is necessary to look back at two historical episodes with similar characteristics. On the one hand, during the 1920s and 1930s in the United States, some actors joined forces to develop a chemurgy aimed at creating industrial products on the basis of agricultural substrates. On the other hand, during the years 1976 to 1980, the crisis in petroleum-based chemistry led to the idea of a revival based on the chemistry of sugars. In this chapter, we will do so by analysing the way actors have defined how the use of renewable resources in substitution of oil should be organised.
This third chapter concludes the first part of the book with a specific focus on the current mainstreamed conceptualisation of the bioeconomy, including expectations and criticisms about its potential societal contribution. Drawing from the green and circular economy – two ideas popularised during the past two decades in the academic, policy, and practitioner communities – the chapter discusses future avenues for the conceptual development and practical implementation of the bioeconomy.
In Chapter 6, the bioeconomy is examined in light of basic notions from the field of ecological economics and sustainability science, such as natural capital substitutability, planetary boundaries, social needs, growth and de/post-growth, justice, and equity. Overall, such notions highlight the need to pursue sustainability solutions that are simultaneously safe for planetary ecological health and just for people across space and time.
