THREAT RECOGNITION IN INCUMBENT FIRMS: A CASE FOR ORGANIZATIONAL VELOCITY

Change is not new, but the speed of change is new. Fueled by a combination of connecting and thinking technologies, the business environment is becoming increasingly dynamic and uncertain. Incumbent firms face a wider variety of threats that vary in frequency of occurrence and financial impact. How effectively firms see these threats, internalize them as important (or not) and act on them in a timely manner (or not) can be critical to their survival. However, the academic literature is incomplete on how firms navigate this threat recognition process from initial observation through action and across different organizational contexts. This qualitative study explores the process of threat recognition in several industries and organizational contexts through in-depth interviews with senior business and military leaders. The objective is to uncover characteristics and processes associated with effective threat recognition. Organizational velocity emerged as a key determinant of success as firms navigate the threat recognition process. Importantly, the pace of organizational velocity is primarily a choice, not a circumstance. This research explores those choices that enable and inhibit organizational velocity, extending the boundaries of disruptive innovation theory and providing practical insights for organization leaders in an increasingly uncertain and turbulent world. Keywords: organizational velocity, threat recognition, uncertainty, disruptive innovatio

Zero-gravity venting of three refrigerants

An experimental investigation of venting cylindrical containers partially filled with initially saturated liquids under zero-gravity conditions was conducted in the NASA Lewis Research Center 5-second zero-gravity facility. The effect of interfacial mass transfer on the ullage pressure response during venting was analytically determined, based on a conduction analysis applied to an infinitely planer (flat) liquid-vapor interface. This pressure response was compared with both the experimental results and an adiabatic decompression computation

“Be authentic”: Authenticity Norms in German Politics and Self-Idealizations of Members of the Bundestag

This contribution goes back to a study of the formative power of identity norms in professional fields of occupation (fine arts and politics). In this article, we focus on the understanding of identity norms that members of the German Bundestag have to meet and/or to cope with. Thus, our research question is which demands professional politicians encounter and which ways of dealing with them are established. Operating at the intersection of governmentality studies, subjectivation analysis and qualitative inquiry, and based on narrative interviews with MPs, this paper demonstrates how in the field of German politics (at federal level) the MPs orientate their professional praxis towards the identity norm of an authentic self and conform to the expectation of a contradiction-free relationship between professional and private lives. In the process, the MPs develop idealizations of their selves in which aspects of their habitus become reflexive. We especially discuss these results against the backdrop of the emergence of modern parliaments and, methodologically, regarding the relation between habitual-implicit and reflexive-explicit structures of knowledge which are especially relevant in subjectivation analysis

Obesity and prostate cancer-specific mortality after radical prostatectomy: results from the Shared Equal Access Regional Cancer Hospital (SEARCH) database.

BackgroundAt the population level, obesity is associated with prostate cancer (PC) mortality. However, few studies analyzed the associations between obesity and long-term PC-specific outcomes after initial treatment.MethodsWe conducted a retrospective analysis of 4268 radical prostatectomy patients within the Shared Equal Access Regional Cancer Hospital (SEARCH) database. Cox models accounting for known risk factors were used to examine the associations between body mass index (BMI) and PC-specific mortality (PCSM; primary outcome). Secondary outcomes included biochemical recurrence (BCR) and castration-resistant PC (CRPC). BMI was used as a continuous and categorical variable (normal <25 kg/m2, overweight 25-29.9 kg/m2 and obese ⩾30 kg/m2). Median follow-up among all men who were alive at last follow-up was 6.8 years (interquartile range=3.5-11.0). During this time, 1384 men developed BCR, 117 developed CRPC and 84 died from PC. Hazard ratios were analyzed using competing-risks regression analysis accounting for non-PC death as a competing risk.ResultsOn crude analysis, higher BMI was not associated with risk of PCSM (P=0.112), BCR (0.259) and CRPC (P=0.277). However, when BMI was categorized, overweight (hazard ratio (HR) 1.99, P=0.034) and obesity (HR 1.97, P=0.048) were significantly associated with PCSM. Obesity and overweight were not associated with BCR or CRPC (all P⩾0.189). On multivariable analysis adjusting for both clinical and pathological features, results were little changed in that obesity (HR=2.05, P=0.039) and overweight (HR=1.88, P=0.061) were associated with higher risk of PCSM, but not with BCR or CRPC (all P⩾0.114) with the exception that the association for overweight was no longer statistical significant.ConclusionsOverweight and obesity were associated with increased risk of PCSM after radical prostatectomy. If validated in larger studies with longer follow-up, obesity may be established as a potentially modifiable risk factor for PCSM

Mechanical Competence and Bone Quality Develop During Skeletal Growth.

Bone fracture risk is influenced by bone quality, which encompasses bone's composition as well as its multiscale organization and architecture. Aging and disease deteriorate bone quality, leading to reduced mechanical properties and higher fracture incidence. Largely unexplored is how bone quality and mechanical competence progress during longitudinal bone growth. Human femoral cortical bone was acquired from fetal (n = 1), infantile (n = 3), and 2- to 14-year-old cases (n = 4) at the mid-diaphysis. Bone quality was assessed in terms of bone structure, osteocyte characteristics, mineralization, and collagen orientation. The mechanical properties were investigated by measuring tensile deformation at multiple length scales via synchrotron X-ray diffraction. We find dramatic differences in mechanical resistance with age. Specifically, cortical bone in 2- to 14-year-old cases exhibits a 160% greater stiffness and 83% higher strength than fetal/infantile cases. The higher mechanical resistance of the 2- to 14-year-old cases is associated with advantageous bone quality, specifically higher bone volume fraction, better micronscale organization (woven versus lamellar), and higher mean mineralization compared with fetal/infantile cases. Our study reveals that bone quality is superior after remodeling/modeling processes convert the primary woven bone structure to lamellar bone. In this cohort of female children, the microstructural differences at the femoral diaphysis were apparent between the 1- to 2-year-old cases. Indeed, the lamellar bone in 2- to 14-year-old cases had a superior structural organization (collagen and osteocyte characteristics) and composition for resisting deformation and fracture than fetal/infantile bone. Mechanistically, the changes in bone quality during longitudinal bone growth lead to higher fracture resistance because collagen fibrils are better aligned to resist tensile forces, while elevated mean mineralization reinforces the collagen scaffold. Thus, our results reveal inherent weaknesses of the fetal/infantile skeleton signifying its inferior bone quality. These results have implications for pediatric fracture risk, as bone produced at ossification centers during children's longitudinal bone growth could display similarly weak points. © 2019 American Society for Bone and Mineral Research
