Observation captures complex organizational phenomena in situ. The literature on this method explains the possible data collection methods but says less about the use and organization of the data collected. As a result, the question of the meaning of observation data remains open. This article explores that question with the focus on a specific form of observation, dynamic observation, which can grasp indeterminate situations whose meaning is elusive for both practitioners and the researcher. Drawing on the work of Ricœur, we propose a conceptual tool kit founded on mimesis. We show that organizing observation data into a plot and narrative, through an inquiry conducted by researchers and practitioners together, can shed light both on the observation data and the situation observed. We embody our method by applying this tool kit to a dynamic observation conducted in a high-risk industry. We discuss the methodological issues of this co-construction of shared meaning and its role in restoring centrality to observation in the management sciences, and resituating the situations and the actors as core concerns.

It has been an outstanding challenge to achieve implantable energy modules that are mechanically soft (compatible with soft organs and tissues), have compact form factors, and are biodegradable (present for a desired time frame to power biodegradable, implantable medical electronics). Here, we present a fully biodegradable and bioabsorbable high-performance supercapacitor implant, which is lightweight and has a thin structure, mechanical flexibility, tunable degradation duration, and biocompatibility. The supercapacitor with a high areal capacitance (112.5 mF cm−2 at 1 mA cm−2) and energy density (15.64 μWh cm−2) uses two-dimensional, amorphous molybdenum oxide (MoOx) flakes as electrodes, which are grown in situ on water-soluble Mo foil using a green electrochemical strategy. Biodegradation behaviors and biocompatibility of the associated materials and the supercapacitor implant are systematically studied. Demonstrations of a supercapacitor implant that powers several electronic devices and that is completely degraded after implantation and absorbed in rat body shed light on its potential uses.

AbstractThe evolution of the structural and kinematic properties of early-type galaxies (ETGs), their scaling relations, as well as their stellar metallicity and age contain precious information on the assembly history of these systems. We present results on the evolution of the stellar mass-velocity dispersion relation of ETGs, focusing in particular on the effects of some selection criteria used to define ETGs. We also try to shed light on the role that in-situ and ex-situ stellar populations have in massive ETGs, providing a possible explanation of the observed metallicity distributions.

AbstractReliable factors predicting the disease course of non-muscle-invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) are unavailable. Molecular subtypes have potential for prognostic stratification of muscle-invasive bladder cancer, while their value for CIS patients is unknown. Here, the prognostic impact of both clinico-pathological parameters, including CIS focality, and immunohistochemistry-based surrogate subtypes was analyzed in a cohort of high-risk NMIBC patients with CIS. In 128 high-risk NMIBC patients with CIS, luminal (KRT20, GATA3, ERBB2) and basal (KRT5/6, KRT14) surrogate markers as well as p53 were analyzed in 213–231 biopsies. To study inter-lesional heterogeneity of CIS, marker expression in independent CIS biopsies from different bladder localizations was analyzed. Clinico-pathological parameters and surrogate subtypes were correlated with recurrence-free (RFS), progression-free (PFS), cancer-specific (CSS), and overall survival (OS). Forty-six and 30% of CIS patients exhibited a luminal-like (KRT20-positive, KRT5/6-negative) and a null phenotype (KRT20-negative, KRT5/6-negative), respectively. A basal-like subtype (KRT20-negative, KRT5/6-positive) was not observed. A significant degree of inter-lesional CIS heterogeneity was noted, reflected by 23% of patients showing a mixed subtype. Neither CIS surrogate subtype nor CIS focality was associated with patient outcome. Patient age and smoking status were the only potentially independent prognostic factors predicting RFS, PFS, OS, and PFS, respectively. In conclusion, further clarification of heterogeneity of surrogate subtypes in HR NMIBC and their prognostic value is of importance with regard to potential implementation of molecular subtyping into clinical routine. The potential prognostic usefulness of patient age and smoking status for high-risk NMIBC patients with CIS needs further validation.

Polak’s (2010) chronometric analyses of Malian jembe music suggested that the characteristic “feel” of individual pieces rests upon nonisochronous subdivisions of the beat. Each feel is marked by a specific pattern of two or three different subdivisional pulses—these being either short, medium, or long. London (2010) called the possibility of more than two different pulse classes into question on psychological and theoretical grounds. To shed light on this issue, 23 professional Malian percussionists and dancers were presented with timing-manipulated phrases from a piece of Malian drumming music called “Manjanin.” In a pairwise comparison experiment, participants were asked: (1) if the items of each pair were same or different, and (2) if different, which of the two was the better example of the characteristic rhythm of Manjanin. While most contrastive pairs were well distinguished and produced clear preference ratings, participants were unable to distinguish short-medium-long patterns from short-long-long patterns, and both were preferred to all other manipulations. This supports London’s claim that, perceptually, there are only two pulse classes. We discuss further implications of these findings for music theory, involving beat subdivision, tempo effects, microtiming, and expressive variation, as well as methodological issues.
