Deliberate Learning and the Evolution of Dynamic Capabilities

This paper investigates the mechanisms through which organizations develop dynamic capabilities, defined as routinized activities directed to the development and adaptation of operating routines. It addresses the role of (1) experience accumulation, (2) knowledge articulation, and (3) knowledge codifi- cation processes in the evolution of dynamic, as well as operational, routines. The argument is made that dynamic capabilities are shaped by the coevolution of these learning mechanisms. At any point in time, firms adopt a mix of learning behaviors constituted by a semiautomatic accumulation of experience and by deliberate investments in knowledge articulation and codification activities. The relative effectiveness of these capability-building mechanisms is analyzed here as contingent upon selected features of the task to be learned, such as its frequency, homogeneity, and degree of causal ambiguity. Testable hypotheses about these effects are derived. Somewhat counterintuitive implications of the analysis include the relatively superior effectiveness of highly deliberate learning processes such as knowledge codification at lower levels of frequency and homogeneity of the organizational task, in contrast with common managerial practice.
Perception and imagery of faces generate similar gender aftereffects

ABSTRACT Visual adaptation is known to bias perception away from the properties of the adapting stimuli, toward opposite properties, resulting in perceptual aftereffects. For example, prolonged exposure to a face has been shown to produce an identity aftereffect, biasing perception of a subsequent face toward the opposite identity. Such repulsive aftereffects have been observed for both visually perceived and visually imagined faces, suggesting that both perception and imagery yield typical aftereffects. However, recent studies have reported opposite patterns of aftereffects for perception and imagery of face gender. In these studies, visually perceived faces produced typical effects in which perception of androgynous faces was biased away from the gender of the adaptor, whereas imagery of the same stimuli produced atypical aftereffects, biasing the perceived gender of androgynous faces toward the gender of the adaptor. These findings are highly unusual and warrant further research. The present study aimed to gather new evidence on the direction of gender aftereffects following perception and imagery of faces. Experiment 1 had participants view and imagine female and male faces of famous and non-famous individuals. To determine the effect of concomitant visual stimulation on imagery and adaptation, participants visualized faces both in the presence and in the absence of a visual input. In Experiment 2, participants were adapted to perceived and imagined faces of famous and non-famous actors matched on gender typicality. This manipulation allowed us to determine the effect of face familiarity on the magnitude of gender aftereffects. Contrary to evidence from previous studies, our results demonstrated that both perception and imagery produced typical aftereffects, biasing the perceived gender of androgynous faces in the opposite direction to the gender of the adaptor. Famous faces yielded largest adaptation effects across tasks. Experiment 2 confirmed that these effects depended on familiarity rather than on sexual dimorphism. In both experiments, this effect was greater for perception than imagery. Additionally, imagery of famous faces produced strongest aftereffects when it was performed in the absence of visual stimulation. The implications of these findings are discussed.
The Prevalence of Notched Audiograms in a Cross-Sectional Study of 12,055 Railway Workers

Objective: Noise-induced hearing loss (NIHL) is one of the most reported occupational diseases internationally. The occurrence of audiometric notches is emphasized in both American and European guidelines for the diagnosis of NIHL. The aim of this study was to describe the prevalence of notched audiograms among railway personnel with and without noise exposure to better assess the usefulness of such notches in the diagnosis of NIHL. Design: The most recent audiogram from 1994 to 2011 of a total of 12,055 railway workers, age 20 to 65 years, was obtained from the medical records of the occupational health service of the Norwegian State Railways (NSB). The prevalences of three types of notched audiograms, Coles notch, notch index, and 4 kHz notch, were computed, in relation to age, sex, and occupational noise exposure. Results: Coles notch in either ear was found in 63% of the male railway maintenance workers, exposed to noise levels of 75 to 90 dB(A), compared with 53% of the non-noise exposed (<70 dB(A)) traffic controllers (p < 0.001). The corresponding figures for the 4 kHz notch were 31% versus 21% (p < 0.001). For the notch index, 61% of the exposed and 51% of the controls had a notched audiogram (p < 0.001). For female workers, the prevalence of audiometric notches was lower, and the differences between noise exposed and nonexposed was smaller than those in men. Increasing age led to an increased prevalence of notches. Conclusions: Audiometric notches commonly occur among both noise-exposed and those not exposed to noise in railway personnel. The usefulness of audiometric notches in the diagnosis of NIHL is therefore limited.
Investigations into Recycling Zinc from Used Metal Oxide Varistors via pH Selective Leaching: Characterization, Leaching, and Residue Analysis

Metal oxide varistors (MOVs) are a type of resistor with significantly nonlinear current-voltage characteristics commonly used in power lines to protect against overvoltages. If a proper recycling plan is developed MOVs can be an excellent source of secondary zinc because they contain over 90 weight percent zinc oxide. The oxides of antimony, bismuth, and to a lesser degree cobalt, manganese, and nickel are also present in varistors. Characterization of the MOV showed that cobalt, nickel, and manganese were not present in the varistor material at concentrations greater than one weight percent. This investigation determined whether a pH selective dissolution (leaching) process can be utilized as a starting point for hydrometallurgical recycling of the zinc in MOVs. This investigation showed it was possible to selectively leach zinc from the MOV without coleaching of bismuth and antimony by selecting a suitable pH, mainly higher than 3 for acids investigated. It was not possible to leach zinc without coleaching of manganese, cobalt, and nickel. It can be concluded from results obtained with the acids used, acetic, hydrochloric, nitric, and sulfuric, that sulfate leaching produced the most desirable results with respect to zinc leaching and it is also used extensively in industrial zinc production.
The Effect of Two Methods of Pomegranate (Punica granatum L) Juice Extraction on Quality During Storage at 4°C

The effect of two extraction methods of pomegranate juice on its quality and stability was evaluated. The first method consisted of separation of the seeds from fruits and centrifugation. The second method consisted of squeezing fruit halves with an electric lemon squeezer. During a period of 72 hours of cold storage at 4°C, the juices were evaluated for the presence of sugars, organic acids, and anthocyanins. Delphinidin 3-glucoside was identified to be the major anthocyanin present at the level of 45–69 mg/L. Among the organic acids, oxalic and tartaric acids dominated. The major sugars detected in pomegranate juice were glucose and sucrose. No significant differences in the content of sugars, organic acids, or anthocyanins in juices obtained through application of the two different extraction methods were detected, with the exception of the drastic decrease of cyanidin 3,5-diglucoside level in juice obtained by seed centrifugation. The pH did not show differences between treatments. Titrable acidity and the level of sugars expressed as °Brix decreased after 32 and 15 hours after extraction, respectively, when juice was obtained by centrifuging the seeds.
UNDERSTANDING THE REGIONAL SPECIFICITY OF NEURONS IN THE TRIGEMINAL SUBNUCLEUS CAUDALIS AND SPINAL DORSAL HORN

Neurons in the trigeminal subnucleus caudalis (Vc) and spinal cord dorsal horn (SDH) play important roles in modulating and relaying pain signals to the higher centers of the central nervous system (CNS). Morphologically, many aspects including a laminated structure, cytoarchitecture and cellular elements in these two central regions are very similar [1,2,3,4] . Most nociceptive afferents with a small-diameter terminate in the superficial laminae of Vc and SDH. Functionally, sensory neurons in Vc and SDH respectively receive nociceptive inputs from the orofacial and other somatic regions, and convey the inputs to higher brain centers [1,2,3,4,5] . According to the mechanoreceptive properties, sensory neurons in both the Vc and SDH are classified into three types. They are low-threshold mechanoreceptive (LTM), wide-dynamic range (WDR) and nociceptive-specific neurons (NS) [1,2,3,4,5] . Because of these similarities Vc has been considered as analogous to SDH [4,6] . However, some differences between Vc and SDH have also been reported. For example, the distribution pattern of substance P (SP) and calcitonin gene related peptide (CGRP) in Vc of adult animals is different from that in SDH. In SDH there is no dual representation of peripheral regions, which can be found in rostral and caudal Vc. A transitional zone found between Vc and trigeminal subnucleus interpolaris plays a special role in sensorimotor function. However, no such region is found in the spinal system [5,7,8] . CNS neurons are regionalized. They are organized as groups through their circuitry. Although it is known that differences in functions among these groups in the adult CNS are predetermined during the development of the neuroepithelium [9,10,11,12,13] , understanding how the regional specificity is developed in the CNS is still a big challenge in neuroscience research. It has recently been found that ninhydrin-reacting small molecules released locally are involved in the region-specific regulation of neuronal development in cultured Vc and SDH neurons [14,15] . In this review we focused on present knowledge about the region-specific regulation of neuronal development in these two CNS regions associated with the transmission of nociceptive signals.
Discovery of Warm and Dense Molecular Gas Surrounding the Ring Nebula G79.29+0.46

We present for the first time the detection of mid-J CO line emission in the outskirts of an evolved massive star, which indicates the presence of warm and/or high-density molecular gas. Aiming to learn about the interplay between evolved massive stars and their surroundings, we have carried out CO J = 2→ 1, J = 3→ 2, and 13CO J = 2→ 1 line observations in a 4′ × 4′ field around the ring nebula G79.29+0.46, which is illuminated by a strong LBV star candidate. The whole field shows extended predominant emission in both CO and 13CO J = 2→ 1 lines, which probably comes from the large cloud which contains the star-forming region DR 15. When this large-scale emission is removed, minor-scale features become evident, particularly in the CO J = 3→ 2 line, strikingly coincident with the ring nebula. The high critical density of CO J = 3→ 2 (some 104 cm−3) gives additional support for the association with the massive star, since high-density molecular gas has more chances to survive in such a harsh environment. This structure may have been produced by the cumulative effect of a strong steady wind in the LBV stage or earlier, which has compressed the surviving parent molecular cloud. In addition, immersed within this CO feature, we have also discovered a higher density clump (at least several ~105 cm−3), unresolved by the telescope and probably having a higher kinetic temperature. Toward the clump, the presence of a jump of 14-16 km s−1 in the gas velocity may indicate the existence of a shock front. This clump may have been created by at least one mass eruption, 103-104 yr ago. Thus, this work shows that not all the molecular gas is destroyed during massive star evolution, and consequently we are dealing with a new laboratory where one can learn about the mass-loss phenomena associated to the brief LBV stage.
Learning curve and motor retention of a video game in young and older adults Curva de aprendizaje y retención motriz de un juego de video en adultos jóvenes y adultos mayores

The purpose of the study was to compare the learning curve and motor retention of the Dance Dance Revolution (DDR) video game in healthy adults. Twenty young (M= 23.9 ± 2.8 yr.) and 18 older adults (M= 60.7 ± 5.9 yr.), were randomly assigned to two experimental conditions: a) DDR 7 trials and b) DDR 14 trials. Participants danced the same song six sessions, followed by a detraining period of eight days. Then participants returned to the laboratory and danced again in order to detect a motor retention effect. A three-way ANOVA revealed mean score interactions (sessions x groups x trials; p = 0.017). Follow-up analyses revealed differences between young and older participants in both trial sessions (p < 0.05). Compared to young adults, older adults showed a learning curve of four sessions when performing 14 trials per session. After eight days of detraining only older participants in the DDR14 condition reduced motor performance. In conclusion, older subjects can learn the DDR game after playing four sessions; however, those dancing the same song 14 times were more likely to reduce their scores after eight days of detraining. Younger participants scored high regardless of the number of trials and sessions with little variability.
The making of a pro-cycling city: Social practices and bicycle mobilities

This article explores the contemporary co-production of bicycle practices in Copenhagen and the heterogeneous work involved in making a city pro-cycling. Attention is given as much to the sayings and doings of everyday commuters, as to planners, physical designs and campaigns. I ask: why, and how, are cycling practices continually (re)produced in Copenhagen and how can they attract so many practitioners? The first section discusses and employs practice theory, as it is well suited for examining practices of cycling. The second section explores how Copenhagen Municipality designed and scripted a cycle-friendly space by installing bike infrastructure, promoting cultural meanings and nourishing user competences. I argue that this is done through a heterogeneous process of normalizing and mainstreaming cycling and making alliances with other commuters. The third section shows how cyclists co-produce cycling practices by performing cycling and by enlisting and passing on knowledge to new practitioners. The concluding section highlights the potentials of practice theory to fully understand cycling, and it unravels some of the problems of Copenhagenizing low-cycling cities.
Association Between Polymorphisms of DRD2, COMT, DBH, and MAO-A Genes and Migraine Susceptibility

AbstractSome epidemiological studies have investigated the relationship between genetic polymorphisms of DRD2, COMT, DBH, and MAO-A and migraine susceptibility, but the results are still inconsistent. Thus, our aim was to further assess the association through a meta-analysis.We examined 5 single nucleotide polymorphisms (SNPs) in 4 genes, including DRD2 rs1799732 and rs6275, DBH rs7239728, MAI-A-VNTR, and COMT rs4680, and performed a meta-analysis of 11 published case–control studies including 3138 cases and 4126 controls. Odd ratios (ORs) with 95% confidence intervals (95% CIs) were used to evaluate the association between the 5 genetic polymorphisms and migraine susceptibility.There was no significant relationship between migraine susceptibility and 4 genetic polymorphisms of DRD2 rs1799732 and rs6275, DBH rs7239728, and MAO-A-VNTR. Nevertheless, decreased risk of migraine was observed to be in association with COMT rs4680 polymorphism in overall analysis (AA vs. GG + GA: OR = 0.76, 95% CI = 0.60–0.97, PHet > 0.642, I2 = 0), and in Caucasian group after subgroup analysis (AA vs. GG + GA: OR = 0.75, 95% CI = 0.58–0.96, PHet > 0.433, I2 = 0). Studied polymorphisms of DRD2, DBH, and MAO-A genes may not be associated with migraine susceptibility. However, COMT rs4680 polymorphism may decrease the risk of migraine, especially in Caucasians. The failure to evaluate environmental influence and provide adjusted effect size estimates highlights the need for additional studies in a large number to take these factors into consideration, thus better elucidating the role of the genes tested in migraine.
Favorable surgical results for patients with nonsmall cell lung cancer over 80 years old: a multicenter survey.

BACKGROUND Surgery for elderly patients, especially those over 80 years old, with primary lung neoplasms is a relatively common treatment according to the increasing elderly population. We reviewed our experiences to evaluate surgical outcomes in over-80-year-old patients with nonsmall cell lung cancer (NSCLC). PATIENTS AND METHODS We reviewed and analyzed the clinical records of 146 consecutive over-80-year-old patients (Group 1) and 926 control patients (65 years old and younger) (Group 2) with NSCLC who underwent surgical resections from 1981 to 2006. RESULTS The mean ages of Group 1 and Group 2 were 82.6 and 56.2 years old, respectively. The ratio of the clinical and pathological Stage I was higher than the Stages II-IV in Group 1, and that of pathological Stage III was higher in Group 2. Segmental and wedge resection were selected more frequently in Group 1, otherwise, pneumonectomy and lobectomy were selected more frequently in Group 2. The ratio of squamous cell carcinoma was higher in Group 1 than in Group 2. When we divided the time of surgeries into decades, the 1980s, 1990s, and 2000s, the ratio of elder to younger patients was clearly increased according to era: 6.6%, 13.7%, and 18.8%. Furthermore, incomplete operation cases were significantly decreased in the two groups. There was no difference of overall survival in either. When examined for overall survival, except for patients with incomplete resection, there was no significant difference between the two groups. CONCLUSIONS Surgery is the convenient treatment for elderly NSCLC patients, especially, for those who can undergo complete resection.
Evolutionary Learning in Signalling Games

We study equilibrium selection by evolutionary learning in monotone signalling games. The learning process is a development of that introduced by Young for static games extended to deal with incomplete information and sequential moves; it thus involves stochastic trembles. For vanishing trembles the process gives rise to strong selection among sequential equilibria. If the game has separating equilibria, then in the long run only play according to a specific separating equilibrium, the so-called Riley equilibrium, will be observed frequently. Also if the game has no separating equilibrium a particular behavior will emerge as the only one observed frequently in the long run. It may or may not correspond to a pooling equilibrium, but if it does, it is to one where both types of sender choose the signal that is best for the ''high'' type when all signals are responded to as if they came from the ''low'' type. This selection is stronger than, and only partly in accordance with, traditional selection based on restrictions on ''out-of-equilibrium'' beliefs.
“A Family for Every Child”: Discursive Constructions of “Ideal” Adoptive Families in Online Foster Adoption Photolistings That Promote Adoption of Children From Foster Care

ABSTRACT Despite documented cultural and institutional preferences for biological family ties, approximately 100,000 children await adoption in the U.S. foster care system. Child welfare professionals have the important task of finding these children permanent families, yet little is known about this process or how “ideal” adoptive families are constructed. Thus, this study critically examines photolistings (N = 104) from www.afamilyforeverychild. org. Findings indicate that discursive constructions of “forever family,” based on chosen family structure and familial performance, counter biology-based understandings of family. Practical applications that might open untapped opportunities to connect children with permanent families are discussed.
Convergence analysis of a finite volume scheme for solving non-linear aggregation-breakage population balance equations

This paper presents stability and convergence analysis of a finite volume scheme (FVS) for solving aggregation, breakage and the combined processes by showing Lipschitz continuity of the numerical fluxes. It is shown that the FVS is second order convergent independently of the meshes for pure breakage problem while for pure aggregation and coupled equations, it shows second order convergent on uniform and non-uniform smooth meshes. Furthermore, it gives only first order convergence on non-uniform grids. The mathematical results of convergence analysis are also demonstrated numerically for several test problems.
On the Stochastic Modeling of Rigid Body Systems with Application to Polymer Dynamics

The stochastic equations of motion for a system of interacting rigid bodies in a solvent are formulated and studied. Three-dimensional bodies of arbitrary shape, with arbitrary couplings between translational and rotational degrees of freedom, as arise in coarse-grained models of polymers, are considered. Beginning from an Euler-Langevin form of the equations, two different, properly invariant, Hamilton-Langevin forms are derived and studied together with various associated measures. Under different conditions depending on the choice of rotational coordinates, the canonical measure is shown to be a stationary solution of an associated Fokker-Planck equation and to always factorize into independent measures on configuration and velocity spaces. Explicit expressions are given for these measures, along with a certain Jacobian factor associated with the three-dimensional rotation group. When specialized to a fully coupled, quadratic model of a stiff polymer such as DNA, our results yield an explicit characterization of the complete set of model parameters.
Mediating Conflict in Concurrent Engineering with a Protocol Based on Utility

Concurrent engineering is an approach to product, process, and organizational design in which experts from many disciplines contnbute at many stages of the product life cycle Even though the design process is mostly cooperative, conflicts among sharply diverging viewpoints may occur, which require negotiated compromise solutions Design advice tools can assist in the process of negotiation by making their critiques and suggestions conveniently available to all members of the product development team Constraint-based languages of sufficient expressive power provide a convenient representation of real-world problems like those encountered in concurrent engineering, and we believe they are a good basis for building such design advice tools In this paper we descnbe a protocol, based on the use of economic utility, by which constraint-based design advice systems can recognize conflict, and support and mediate negotiation fairly
