Putting the Human Back in ‘‘Human Research Methodology’’: The Researcher in Mixed Methods Research:

Abstract: When we were asked to write an editorial for Journal of Mixed Methods Research, the request came as an invitation to share some of our ‘‘insights’’ about mixed methodology and its trajectory, based on our experiences with the second edition of the Handbook of Mixed Methods in the Social and Behavioral Sciences (hereafter referred to as the Handbook; Tashakkori & Teddlie, 2010). In this editorial, we share with our current readers some of the personal reflections, intellectual challenges, and professional struggles that we experienced during what we have called ‘‘the journey.’’ It is hoped that these reflections will summarize and expand on the comments we made in the Preface and Epilogue of the Handbook. We chose the title for this editorial for at least two reasons. One is that we would like to share our own reflections as human researchers, hoping to demonstrate that we have evolved from technocrats to methodologists. Second, we hope to convey our belief in the fact that human researchers are, more than anything else, human themselves. As such, they enjoy the capabilities of human problem solvers, while trying to identify and reduce the perils and pitfalls that are at times evident in our day-to-day problem solving. We will suggest that mixed methods capitalize on these capabilities, while also increasing the potential for credible and trustworthy conclusions.

Bacterial Communities of the Coronal Sulcus and Distal Urethra of Adolescent Males

Abstract: Lactobacillus-dominated vaginal microbiotas are associated with reproductive health and STI resistance in women, whereas altered microbiotas are associated with bacterial vaginosis (BV), STI risk and poor reproductive outcomes. Putative vaginal taxa have been observed in male first-catch urine, urethral swab and coronal sulcus (CS) specimens but the significance of these observations is unclear. We used 16 S rRNA sequencing to characterize the microbiota of the CS and urine collected from 18 adolescent men over three consecutive months. CS microbiotas of most participants were more stable than their urine microbiotas and the composition of CS microbiotas were strongly influenced by circumcision. BV-associated taxa, including Atopobium, Megasphaera, Mobiluncus, Prevotella and Gemella, were detected in CS specimens from sexually experienced and inexperienced participants. In contrast, urine primarily contained taxa that were not abundant in CS specimens. Lactobacilllus and Streptococcus were major urine taxa but their abundance was inversely correlated. In contrast, Sneathia, Mycoplasma and Ureaplasma were only found in urine from sexually active participants. Thus, the CS and urine support stable and distinct bacterial communities. Finally, our results suggest that the penis and the urethra can be colonized by a variety of BV-associated taxa and that some of these colonizations result from partnered sexual activity.

A model of supply chain and supply chain decision‐making complexity

Abstract: Purpose – The objective of this paper is to develop a comprehensive model of supply chain and supply chain decision‐making complexity that provides an understanding of the drivers of supply chain complexity and strategies to manage supply chain and supply chain decision‐making complexity and outcomes.Design/methodology/approach – Grounded theory methodology is employed to build a theory of supply chain and supply chain decision‐making complexity and develop propositions related to antecedents, moderators, and outcomes of supply chain complexity. In addition, extensive literature review and informal interactions with a number of supply chain professionals have been used to validate the theory.Findings – In addition to identifying the antecedents of supply chain complexity, the authors explore strategic, human cognitive ability, and tactical moderators for managing supply chain complexity.Research limitations/implications – The comprehensive framework presented in the paper builds a theory of supply chain a...
