In lieu of an abstract, here is a brief excerpt of the content:My Gratifying Testimonial of My Extended Warranties of LifeDanette RaginMy name is Danette Ragin. I am a 2-time kidney recipient who has been diagnosed with ESRD (End Stage Renal Disease). Both transplants were performed in Baltimore, Maryland. I am also a 3-time Donor Family Member and the proud Mom of a living donor.I received the first kidney from a deceased donor on June 22, 2008. The donor (...) was traveling thru Maryland with her family on vacation and experienced heart complications. My second kidney was donated to me by my youngest daughter Angel on December 20. 2016. I am thankful to God for both of my extended warranties. I’d like to share a little about my journey with you.Around the year 2002, I started seeing my PCP (Primary Care Physician) for terrible migraine headaches, which on occasions lasted for weeks. After several tests, she expressed her concerns. I had been spilling protein in my urine and my kidney function was showing some abnormalities. My PCP sent me to see a neurologist after several failed attempts to gain some type of reprieve from the nerve-racking headaches. My nephrologist confirmed my PCP’s diagnosis, and I had visits with the nephrologist every 6 months until they noticed a substantial change.“Ah, Mrs. Ragin, you’re in the beginning stage of End Stage Renal Disease”. Boom! (That hit me like a ton of bricks.) “Umm, you mean I have kidney failure! No! Not me. I’ve worked in dialysis. That can’t happen to me!”Of course, I was in complete denial. Both my PCP and nephrologist were very supportive mentally, physically, emotionally, and even spiritually. This information was so devastatingly painful that I started working harder and longer. I turned into a Superwoman with my family, work, and church. I was trying to drown out the fact that my health was being compromised, refusing to believe this could happen to me. I started to slow down in my daily functions, my appetite decreased, and I lost weight as a result. I thought that my weight loss was bringing my “Sexy Back,” only to realize that I am not exempt from sickness. My nephrologist assured me of a possible solution. He advised me to have my name placed on the waitlist of one of the transplant centers in Maryland.In October 2006, I had surgery to have an A/V fistula placed in my left arm to prepare for possible dialysis treatments in the future. In January 2007, I went to be evaluated for a kidney transplant. I was given 6 weeks to complete all required tests to secure a place on the transplant waiting list. Determination allowed me to complete all tests within 2 weeks.In April 2007, I was approved to be placed on the transplant list. In October, I had a PDC (Peritoneal Dialysis Catheter) placed in my abdomen so that I could dialyze myself at home. I loved it but it didn’t love me. It was removed in January 2008. Right afterward, I received my first unsuccessful call to be transplanted. (The kidneys were cystic and could not be used.) “Bummer.” I also received another call in April 2008 (Easter Sunday). Those kidneys were [End Page 134] at another hospital in Maryland, so if the waiting patient at their facility refused the kidney, I would be next in line. The patient accepted the donation. It wasn’t my turn yet.In the meantime, I had already started hemo-dialysis in mid-March 2008. On Saturday, June 21, 2008, while enjoying the weekend with my family, I received a call around 2:30 p.m. My youngest daughter and I were out shopping. We were in a crowded store that was going out of business, and I felt my phone vibrate. I noticed a slightly familiar number. I stepped out of the store to retrieve the call.“Mrs Ragin...Me: Yes.“Danette Ragin...Me: Yes.“We are calling from the University with an organ offer for you!”I told them they had me at the sight of the first few digits of the phone number they were calling from!In June...

What causes unethical behavior and what can we learn from those individuals who have had spectacular ethical lapses? The profiles of six prominent individuals, including Dennis Levine, Charles Keating, and Robert Citron are examined to try to provide some insight into what lead them down the slippery slope to criminal and unethical behavior. What we found is that all six certainly knew that they were breaking the law and most went to extra-ordinary lengths to cover up what they were doing. (...) Additionally, we found that each individual had attained a position of authority that enabled them to break the law without being seriously challenged by others who knew, or suspected, what was being done. Each person was highly compensated for their efforts, yet, they choose to engage in unethical and illegal activities in the pursuit of just a little more money or power. (shrink)

IntroductionChildren with severe physical disabilities are denied their fundamental right to move, restricting their development, independence, and participation in life. Brain-computer interfaces (BCIs) could enable children with complex physical needs to access power mobility (PM) devices, which could help them move safely and independently. BCIs have been studied for PM control for adults but remain unexamined in children. In this study, we explored the feasibility of BCI-enabled PM control for children with severe physical disabilities, assessing BCI performance, standard PM skills (...) and tolerability of BCI.Materials and methodsPatient-oriented pilot trial. Eight children with quadriplegic cerebral palsy attended two sessions where they used a simple, commercial-grade BCI system to activate a PM trainer device. Performance was assessed through controlled activation trials (holding the PM device still or activating it upon verbal and visual cueing), and basic PM skills (driving time, number of activations, stopping) were assessed through distance trials. Setup and calibration times, headset tolerability, workload, and patient/caregiver experience were also evaluated.ResultsAll participants completed the study with favorable tolerability and no serious adverse events or technological challenges. Average control accuracy was 78.3 ± 12.1%, participants were more reliably able to activate (95.7 ± 11.3%) the device than hold still (62.1 ± 23.7%). Positive trends were observed between performance and prior BCI experience and age. Participants were able to drive the PM device continuously an average of 1.5 meters for 3.0 s. They were able to stop at a target 53.1 ± 23.3% of the time, with significant variability. Participants tolerated the headset well, experienced mild-to-moderate workload and setup/calibration times were found to be practical. Participants were proud of their performance and both participants and families were eager to participate in future power mobility sessions.DiscussionBCI-enabled PM access appears feasible in disabled children based on evaluations of performance, tolerability, workload, and setup/calibration. Performance was comparable to existing pediatric BCI literature and surpasses established cut-off thresholds (70%) of “effective” BCI use. Participants exhibited PM skills that would categorize them as “emerging operational learners.” Continued exploration of BCI-enabled PM for children with severe physical disabilities is justified.

Thousands of youth suffering from acquired brain injury or other early-life neurological disease live, mature, and learn with only limited communication and interaction with their world. Such cognitively capable children are ideal candidates for brain-computer interfaces. While BCI systems are rapidly evolving, a fundamental gap exists between technological innovators and the patients and families who stand to benefit. Forays into translating BCI systems to children in recent years have revealed that kids can learn to operate simple BCI with proficiency akin (...) to adults. BCI could bring significant boons to the lives of many children with severe physical impairment, supporting their complex physical and social needs. However, children have been neglected in BCI research and a collaborative BCI research community is required to unite and push pediatric BCI development forward. To this end, the pediatric BCI Canada collaborative network was formed, under a unified goal to cooperatively drive forward pediatric BCI innovation and impact. This article reflects on the topics and discussions raised in the foundational BCI-CAN meeting held in Toronto, ON, Canada in November 2019 and suggests the next steps required to see BCI impact the lives of children with severe neurological disease and their families.

The main purpose of this article is to bring Ragin’s recent methodological contributions, which build on ideas borrowed from fuzzy logic, to the attention of management scholars. To demonstrate the possible use of the techniques developed by Ragin in management research, three specific examples for their likely applications are presented: the replications of Porter’s diamond framework for Turkey, Greece and Canada. The article concludes that Ragin’s systematic techniques prove helpful in making explicit the process of comparing qualitative (...) evidence derived from case study research, and thus they deserve greater attention in the management literature.

In "The Comparative Method" Ragin (1987) has outlined a procedure of Boolean causal reasoning operating on pure coincidence data that has meanwhile become widely known as QCA (Qualitative Comparative Analysis) among social scientists. QCA -- also in its recent form as presented in Ragin (2000) -- is designed to analyze causal structures featuring one effect and a possibly complex configuration of mutually independent direct causes of that effect. The paper at hand presents a procedure of causal reasoning that (...) operates on the same type of empirical data as QCA and that implements Boolean techniques related to the ones resorted to by QCA, yet, in contrast to QCA, the procedure introduced here successfully identifies causal structures involving both mutually dependent causes, i.e. causal chains, and multiple effects, i.e. epiphenomena. In this sense, the paper at hand generalizes QCA. (shrink)

How can we make complexity work as part of a programme of engaged social science? This article attempts to answer that question by arguing that one way to do this is through a reconstruction of a central tool of a distinctively social science – the comparative method – understood as a procedure for elucidating the complex and multiple systems of causation that generate particular trajectories towards a desired future from the multiple sets of available futures. The article distinguishes between ‘simplistic (...) complexity’ and ‘complex complexity’. ‘Simplistic complexity’ seeks to explain emergence in complex systems as the product of simple rules and defines complex science as the process of establishing such rules. It can and does serve as the basis of technocratic social engineering in the interest of the powerful. In contrast ‘complex complexity’ recognizes the significance of social structure and willed social agency and does not reduce emergence to the mere working out of a restricted set of rules. Research programmes informed by this second approach must necessarily engage with social actors in context – they must be dialogical. This opens up the possibility of ‘complex complexity’ as a frame of reference for action-research directed towards the transformation of complex social systems. Comparative methods, and in particular Ragin’s qualitative comparative analysis approach, when deployed as part of such a programme, can provide meaningful information about the range of possible futures and the different configurations of causes which might generate particular desired social outcomes.

For a long time, regularity accounts of causation have virtually vanished from the scene. Problems encountered within other theoretical frameworks have recently induced authors working on causation, laws of nature, or methodologies of causal reasoning – as e.g. May (Kausales Schliessen. Eine Untersuchung über kausale Erklärungen und Theorienbildung. Ph.D. thesis, Universität Hamburg, Hamburg, 1999), Ragin (Fuzzy-set social science. Chicago: University of Chicago Press, 2000), Graßhoff and May (Causal regularities. In W. Spohn, M. Ledwig, & M. Esfeld (Eds.), Current issues (...) in causation (pp. 85–114). Paderborn: Mentis, 2001), Swartz (The concept of physical law (2nd ed.). http://www.sfu.ca/philosophy/physical-law/, 2003), Halpin (Erkenntnis, 58, 137–168, 2003) – to direct their attention back to regularity theoretic analyses. In light of the latest proposals of regularity theories, the paper at hand therefore reassesses the criticism raised against regularity accounts since the INUS theory of causation of Mackie (The cement of the universe. A study of causation. Oxford: Clarendon Press, 1974). It is shown that most of these objections target strikingly over-simplified regularity theoretic sketches. By outlining ways to refute these objections it is argued that the prevalent conviction as to the overall failure of regularity theories has been hasty. (shrink)

Pragmatic Critical Realism has been acclaimed by several scholars as one of the most versatile, application friendly and philosophically consistent paradigms for the social sciences, especially management research (Fleetwood and Ackroyd 2004). One of the more visible methodological offshoots of this epistemological school, being the case study, which has been extensively deployed as a dominant method in strategic management, organizational studies and marketing literatures. Until recently, there was some consternation in the academic world about the insufficiency of recourses available to (...) aggregate individual case studies and extract more generalizable learnings within delimited boundaries. However, the development of the QCA (Qualitative Comparative Analysis) by Ragin (2000; 2014) has changed that perception. In this paper, we argue that all of these case study-based methods, especially as they relate to Norbert Elias’ conception of figurations, and all of which fall under the broader heading of the Abduction methodology; are especially suited to gaining marketing insights in emerging market economies for a host of reasons. This is the issue that we seek to explore through theoretical argumentation and to establish with a review of the methods literature. (shrink)

Qualitative comparative analysis (QCA) opens up two new forms of knowledge: (1) knowing about alternative pathways to one outcome (equifinality) and (2) perceiving nuances of necessary cause and sufficient cause. Several misunderstandings of QCA occur in the article by Lucas and Szatrowski (this volume, p. 1). First, there are minor problems with expressions. Second, there are differences between their philosophy of science (arguments 1, 2, and 3 below) and a realist approach. Third, they misinterpret what was meant by sufficient and (...) necessary cause (arguments 4 and 5 below). The minor problems with expressions arise in sections 2.2 and 3. In section 2.2, the authors define consistency, but here they miss out on two key points. First, they neglect to say that this particular measure of consistency is a measure of sufficiency of cause, not of necessary cause. Second, they ignore the way that the consistency level exists for each possible configuration of characteristics. A configuration can be shown in one row of a truth table, with n1 = 28, n2 = 17 within a larger sample of 155, and so on (see Byrne 2009:262). Using QCA’s definition of “consistency,” we can discern more about the pattern of causality than one might initially expect. This learning is possible whether N overall is 155, or just 39, or thousands of cases. The essential task is to simplify and rank the list of configurations (Ragin 2001, 2006). (shrink)

The first part of this paper shows that Qualitative Comparative Analysis (QCA)--also in its most recent forms as presented in Ragin (2000, 2008)--, does not correctly analyze data generated by causal chains, which, after all, are very common among causal processes in the social sciences. The incorrect modeling of data originating from chains essentially stems from QCA’s reliance on Quine-McCluskey optimization to eliminate redundancies from sufficient and necessary conditions. Baumgartner (2009a,b) has introduced a Boolean methodology, termed Coincidence Analysis (CNA), (...) that is related to QCA, yet, contrary to the latter, does not eliminate redundancies by means of Quine-McCluskey optimization. The second part of the paper applies CNA to chain-generated data. It will turn out that CNA successfully detects causal chains in small-N data. (shrink)
