The unleashing of Creative Potential from Exiting Firms ? not really?

A growing literature sees labour mobility as a source of knowledge diffusion that benefits the receiving company. However, labour mobility is not necessarily a source of positive knowledge transfer, but also leads to destruction of knowledge. This paper explores what happens to the employees from failing companies and how their skills are being redeployed. It is based on four different cases of firm exit from the shipbuilding industry. The analysis is based on detailed micro data that allow us to follow the mobility of all the laid-off employees. The exit processes are quite diverse and so are the future employment careers of the redundant workers. The closure of each shipyard is described in detail and regression analysis is applied to each case in order to uncover factors that may lead to re-employment. We find that the workers end up in various industries partly depending on the regional industrial environment. The highly educated

Deformation Capacity and Shear Strength of Fiber-Reinforced Cement Composite Flexural Members Subjected to Displacement Reversals

The behavior of fiber-reinforced cement composite FRCC flexural members under large displacement reversals was experi- mentally evaluated. Emphasis was placed on estimating the displacement capacity and shear strength of members constructed with strain-hardening FRCC materials. Two types of fibers were used: Ultrahigh molecular weight polyethylene fibers and steel hooked fibers in volume fractions ranging between 1.0 and 2.0%. The primary experimental variables were: 1 fiber type and volume fraction; 2 type of cement-based matrix concrete or mortar; 3 average shear stress demand at flexural yielding; and 4 shear resistance provided through hoops versus total shear demand. All specimens constructed with a strain-hardening FRCC, with or without web reinforcement, exhibited drift capacities of at least 4.0%. A shear stress level of 0.30fc MPa represented a lower bound for which no shear failure occurred in the strain-hardening FRCC test specimens, regardless of the member inelastic rotation demand. In addition, buckling of longitudinal reinforcement in the strain-hardening FRCC members without web reinforcement was not observed up to plastic hinge rotations of 4.0%.
Rules of Program Behavior

We propose a framework for identifying, organizing, and communicating learning objectives that involve program semantics. In this framework, detailed learning objectives are written down as rules of program behavior (RPBs). RPBs are teacher-facing statements that describe what needs to be learned about the behavior of a specific sort of programs. Different programming languages, student cohorts, and contexts call for different RPBs. Instructional designers may define progressions of RPB rulesets for different stages of a programming course or curriculum; we identify evaluation criteria for RPBs and discuss tradeoffs in RPB design. As a proof-of-concept example, we present a progression of rulesets designed for teaching beginners how expressions, variables, and functions work in Python. We submit that the RPB framework is valuable to practitioners and researchers as a tool for design and communication. Within computing education research, the framework can inform, among other things, the ongoing exploration of “notional machines” and the design of assessments and visualizations. The theoretical work that we report here lays a foundation for future empirical research that compares the effectiveness of RPB rulesets as well as different methods for teaching a particular ruleset.
Transit‐Time and Temperature Control the Spatial Patterns of Aerobic Respiration and Denitrification in the Riparian Zone

During the flow of stream water from losing reaches through aquifer sediments, aerobic and anaerobic respiration (denitrification) can deplete dissolved oxygen and nitrate (NO3−), impacting water quality in the floodplain and downstream gaining reaches. Such processes, which vary in time with short and long‐term changes in stream flow and temperature, need to be assessed at the stream corridor scale to fully capture their effects on net turnover, but this has rarely been done. To address this gap, we combine a fully‐integrated 3D transient numerical flow model with temperature‐dependent reactive transport along advective subsurface flow paths to assess aerobic and anaerobic respiration dynamics at the stream corridor scale in a predominantly losing stream. Our results suggest that given carbon availability (as an electron donor), complete NO3− removal occurred further away from the stream after complete oxygen depletion and was relatively insensitive to variations in temperature and transit‐times. Conversely, transit‐times and oxygen concentrations constrained nitrate removal along short hyporheic flow paths. Even under limited carbon availability and low‐temperatures, NO3− removal fractions ( RNO3 ) will be greater at locations further from the stream than along shorter hyporheic flow paths ( RNO3 = 0.4 and RNO3 = 0.1, respectively). With increasing temperature, the relative effects of stream flow and solute concentrations on biogeochemical turnover and the redox zonation around the stream decreased. The study highlights the importance of seasonal variations of stream flow and temperature for water quality at the stream‐corridor scale. It also provides an adaptive framework to assess and quantify reach‐scale biogeochemical turnover around dynamic streams.
Immunomodulatory Actions of Mesenchymal Stromal Cells (MSCs) in Osteoarthritis of the Knee

Cellular therapy offers regeneration which curbs osteoarthritis of the knee. Among cellular therapies, mesenchymal stromal cells (MSCs) are readily isolated from various sources as culture expanded and unexpanded cellular population which are used as therapeutic products. Though MSCs possess a unique immunological and regulatory profile through cross-talk between MSCs and immunoregulatory cells (T cells, NK cells, dendritic cells, B cells, neutrophils, monocytes, and macrophages), they provide an immunotolerant environment when transplanted to the site of action. Immunophenotypic profile allows MSCs to escape immune surveillance and promotes their hypoimmunogenic or immune-privileged status. MSCs do not elicit a proliferative response when co-cultured with allogeneic T cells in vitro. MSCs secrete a wide range of anti-inflammatory mediators such as PGE-2, IDO, IL-1Ra, and IL-10. They also stimulate the resilient chondrogenic progenitors and enhance the chondrocyte differentiation by secretion of BMPs and TGFβ1. We highlight the various mechanisms of MSCs during tissue healing signals, their interaction with the immune system, and the impact of their lifespan in the management of osteoarthritis of the knee. A better understanding of the immunobiology of MSC renders them as an efficient therapeutic product for the management of osteoarthritis of the knee.
Activation and Role of Astrocytes in Ischemic Stroke

Ischemic stroke refers to the disorder of blood supply of local brain tissue caused by various reasons. It has high morbidity and mortality worldwide. Astrocytes are the most abundant glial cells in the central nervous system (CNS). They are responsible for the homeostasis, nutrition, and protection of the CNS and play an essential role in many nervous system diseases’ physiological and pathological processes. After stroke injury, astrocytes are activated and play a protective role through the heterogeneous and gradual changes of their gene expression, morphology, proliferation, and function, that is, reactive astrocytes. However, the position of reactive astrocytes has always been a controversial topic. Many studies have shown that reactive astrocytes are a double-edged sword with both beneficial and harmful effects. It is worth noting that their different spatial and temporal expression determines astrocytes’ various functions. Here, we comprehensively review the different roles and mechanisms of astrocytes after ischemic stroke. In addition, the intracellular mechanism of astrocyte activation has also been involved. More importantly, due to the complex cascade reaction and action mechanism after ischemic stroke, the role of astrocytes is still difficult to define. Still, there is no doubt that astrocytes are one of the critical factors mediating the deterioration or improvement of ischemic stroke.
Comparison of RBSOA of ESTs with IGBTs and MCTs

The reverse biased safe operating area (RBSOA), at snubberless inductive load state, of 600 V and 2500 V emitter switched thyristors (ESTs) has been analyzed numerically and experimentally for the first time and compared to those for the IGBT and MCT. The dependence of the RBSOA upon the P base resistance (R/sub b/) in the main thyristor structure of the EST, which affects the triggering and holding currents of the device, has also been investigated. Two types of destructive failure mechanisms have been identified. One is due to the voltage-induced avalanche multiplication, the other is attributed to the current-induced latch-up of the parasitic thyristor. Physical analysis of the RBSOA's configuration is also discussed.
Retrospective perceptions and views of engineering students about physics and engineering practicals

Hands-on practical work in physics and engineering has a long and well-established tradition in Australian universities. Recently, however, the question of whether hands-on physics and engineering practicals are useful for engineering students and whether they could be deleted or whether these could be replaced with computer simulations has been raised, mainly due to cost-cutting exercises. In order to ascertain the usefulness of hands-on engineering practicals and first year practical physics classes to their engineering degree, a retrospective survey was carried out with third year engineering students. The general picture that emerges from the survey indicates that the majority of the students found hands-on physics and engineering practicals preferable to simulations on a computer and that practical work is useful not only for linking theory to practicals but also for gaining technical skills.
Scene Content and Runway Breadth Effects on Simulated Landing Approaches

Eight experienced pilots flew landing approaches in a light-aircraft simulator with a computer-generated landing display. Scene content and runway breadth were manipulated. Approaches were lower with reduced scene content and to the narrow runways, and trial-to-trial variability was higher with reduced scene content. There was no significant interaction between scene content and runway breadth. The data were used to evaluate two projective geometry models for prediction of glideslope control during an aircraft approach to landing. These models did not permit an entirely satisfactory account of the data. We conclude that the landing approach is guided by visual properties other than those entered into these models.
Exploring the structural relationships between high school students’ perceptions of science learning environment, their motivation and self-regulation: evidence from Iran

ABSTRACT Background Students’ perceptions of learning environment is known as the most frequent construct related to their learning outcomes. Students’ motivation in learning science (i.e. personal mastery goals orientation, self-efficacy, and task-value) and self-regulation are among the outcome variables that are affected by their perceptions of science learning environment (i.e. perceptions of their parents, school, and science teacher’s mastery goals emphases, and peers’ mastery goals orientation). Purpose The purpose of the current study was to investigate the relations between environmental factors of students’ perceptions of their parents, school, and science teacher’s mastery goals emphases, peers’ mastery goals orientation, and the internal constructs of students’ motivational beliefs and self-regulation in science learning. Sample Participants were 475 Iranian students at lower secondary schools. Design and method A cross-sectional and correlational research design was employed in this study. Data were collected using a questionnaire consisted of three measures of perceptions of science learning environment, motivation, and self-regulation, which the participants were asked to complete. Structural equation modeling (SEM) and a bootstrap procedure were used to estimate the variables’ direct and mediated relationships. Results Results revealed that perceived peers’ mastery goals orientation and perceived parents’ mastery goals emphasis positively predicted personal mastery goals orientation. In addition, the results indicated that perceived teacher’s mastery goals emphasis positively predicted task-value. Moreover, task-value and self-efficacy were found to have a significant direct effect on self-regulation. Conclusions These findings provide novel insight into the role of environmental factors in students’ motivation and self-regulation in science learning. In particular, science teachers are suggested to focus on encouraging students to adopt higher levels of mastery goals orientation in science learning activities, with regards to the significant mediating role of personal mastery goals orientation between perceptions of science learning environment and other motivational beliefs.

Effect of microwave and steam treatment on the thermo-hygro-plasticity of beech wood

The effects of microwave and steam treatment were analyzed relative to the immediate (thermo-hygro-plasticity) and post-assessed (permanent changes) properties of wood. The study was conducted using European beech (Fagus sylvatica L.) standard and 1.5 times up-scaled (only for microwave-heated and reference samples) bending specimens tested in a static three-point loading mode. The specimens were plasticized by heat and moisture (1) separately and (2) simultaneously by heating moist specimens using (i) various microwave regimes in continuous mode, and (ii) heated saturated steam in discontinuous mode. Oven-dried specimens tested at 20 °C served as references. The thermo-hygro-plasticity was studied immediately after treatment, whereas the permanent changes were assessed after oven-drying of plasticized specimens to 0% moisture content. Permanent structural changes were analyzed using scanning electron microscopy. Microwave treatment increased the plasticity of wood (decreasing the modulus of elasticity by 70%) comparably to steam treatment, when the output moisture content was 30% or higher. A similar degree of plasticity was found in up-scaled specimens heated by microwaves. Further analyses confirmed that microwave treatment did not cause any permanent damage to wood structure or reduce mechanical performance. The results showed that microwave treatment is an efficient alternative to steaming when plasticizing moist wood.
Review of SAW oscillator performance

State-of-the-art phase noise performance has been demonstrated for both surface acoustic wave (SAW) resonator and delay line stabilized oscillators. The same basic feedback-loop oscillator design philosophy was applied in each case in order to achieve these results. This paper reviews the design, fabrication, component selection, and performance for an extremely low-noise SAW resonator hybrid circuit oscillator. Finally, several recent results including the flicker noise of SAW resonator devices and the vibration sensitivity of all quartz package SAW resonators are discussed in the context of potential SAW oscillator performance enhancements
Bladder Cancer Variant Histologies: Epidemiology, Diagnosis, Treatment and Prognosis

Bladder cancer (BC) is an increasingly frequent cancer worldwide, being currently the sixth most frequent tumor and the thirteenth leading cause of cancer death. Among all BC cases, pathologists have identified several histomorphologies different from the conventional urothelial carcinoma. Although rare, these histologic variants have a distinct growth pattern, an altered cell differentiation and an unusual clinical behavior, especially concerning clinical presentation at diagnosis, response to the standard treatment and prognosis. Therefore, an updated review of this topic should be useful to aid clinicians in a better evidence-based decision-making. This chapter aims to summarize the current literature on the most common histologic variants regarding their epidemiology, clinical presentation at diagnosis, treatment options and prognosis. This includes both non-muscle invasive BC and muscle invasive BC as well as metastatic disease. A special focus will be placed on the role of neoadjuvant chemotherapy and early cystectomy and its prognostic implications.
In Bureaucrats we Trust? Good Governance and Trust in Civil Servants

While a sizeable literature exists that examines individuals’ trust in government, far less attention has been paid to analyzing trusting attitudes in civil servants - the agents of government with whom citizens have the most contact and interaction. Previous studies have found a noticeable link between public sector performance and the level of trust citizens have in public institutions. However, questions remain as to whether it is the outcomes that the public sector produces or otherwise the process that is used that most influences trusting attitudes. The data used in the analysis comes from the 2016 International Social Survey Programme (ISSP) module “Role of Government V. ” Data from national samples drawn from 23 OECD countries are examined using multilevel logistic regression. The results indicate that individuals living in countries characterized by better governance indicators are more trusting of civil servants than those in countries where procedural performance is poorer.
High-energy heavy-ion-induced charge transport across multiple junctions

High-energy heavy ion experiments and numerical simulations show that two or more junctions bridged by an ion track respond in a coupled manner. The potential difference across the structure strongly affects the amount of charge collected at each of the junctions. Experiments with 1.7 GeV /sup 197/Au ions indicate that, for emitter biases less than or equal to 0.0 volts and potential differences of 5 or more volts, more charge may be collected at a junction than was initially deposited by the ion. Simulations show that, when an ion track intersects multiple junctions of a device, the responses of the individual junctions cannot be modeled independently of each other. Simulation and experimental results indicate that charge transport in a multiple junction structure cannot be modeled using simple geometry or funneling assumptions.
Earthquake dynamics constrained from laboratory experiments: new insights from granular materials

The traction evolution is a fundamental ingredient to model the dynamics of an earthquake rupture which ultimately controls, during the coseismic phase, the energy release, the stress redistribution and the consequent excitation of seismic waves. In the present paper we explore the use of the friction behavior derived from laboratory shear experiments performed on granular materials at low normal stress. We find that the rheological properties emerging from these laboratory experiments can not be described in terms of preexisting governing models already presented in literature; our results indicate that neither rate–and state–dependent friction laws nor nonlinear slip–dependent models, commonly adopted for modeling earthquake ruptures, are able to capture all the features of the experimental data. Then, by exploiting a novel numerical approach, we directly incorporate the laboratory data into a code to simulate the fully dynamic propagation of a 3–D slip failure. We demonstrate that the rheology of the granular material, imposed as fault boundary condition, is dynamically consistent. Indeed, it is able to reproduce the basic features of a crustal earthquake, spontaneously accelerating up to some terminal rupture speed, both sub– and supershear.
