More Women in Tech? Evidence from a Field Experiment Addressing Social Identity

We study the impact of using informational messaging aimed at encouraging women to seek a career in technology and the resulting trade-offs for organizations pursuing recruitment strategies of this kind. Our treatment, implemented through two field experiments among potential applicants to a five-month software-coding program targeted at low-income women in Peru and Mexico, counterbalances the strong male stereotype associated with a career in tech. Although our informational messages substantially increase application rates, including candidates at the top of the cognitive skill distribution, they introduce negative selection on cognitive skills, implying a higher cost of screening. Moreover, we observe selection on the noncognitive dimensions addressed with the treatment (e.g., stronger gender stereotypes and traditional norms). This points to the barriers that preclude more women from applying to tech positions, as well as the trade-offs for organizations of adopting such a strategy.

Helicobacter pylori — Current Therapy and Future Therapeutic Strategies

Helicobacter pylori (H pylori) is a spiral-shaped bacterium that is attached to or just above the gastric mucosa. The organism can persist in the stomach indefinitely and may not cause clinical illness for many years after infection [1]. Indeed, a large number of infected patients never develop any symptoms [2, 3]. However, literature has also associated H pylori infection with gastritis and gastric malignancies (gastric adenocarcinoma and MALT-lymphoma) [4]. Chronic H pylori infection has also been associated with several extra intestinal diseases, such as autoimmune thrombocytopenia, sideropenic anemia and chronic urticaria but the patho‐ genesis is still not known [5]. H pylori gastric infection is one of the most prevalent infectious diseases worldwide with an estimate of 40%-50% of the world population [3]. Remarkable differences are due to geographical, socio-economic and demographic factors [6]. H pylori transmission is still not completely understood. In addition, among infected patients, the reasons why only some develop symptoms is still a matter of speculations. Studies suggested that H.pylori is also transmitted from domestic animals like cat and sheep, but humans are the primary reservoir of H pylori infection [7, 8]. Several tests are available to detect H pylori in patients with ulcer or dyspepsia. The more commonly used tests are the evaluation of biopsy specimens during upper gastrointestinal tract (GI)I endoscopy, the detection of serum anti H pylori antibodies and breath tests with 13C-labeled urea (9-11) The discovery that most upper gastrointestinal diseases are the consequence of H pylori infection that can be treated with antibacterials, is an important medical advance [12]. Although, in the last few decades, H pylori eradication has been standardized, occurrence of resistance to therapeutic regimens is a growing problem [3, 14]. The purpose of this paper is to provide an appraisal of the most
Dual Arm Manipulation using Constraint Based Programming

In this paper, we present a technique for online generation of dual arm trajectories using constraint based programming based on bound margins. Using this formulation, we take both equality and inequality constraints into account, in a way that incorporates both feedback and feedforward terms, enabling e.g. tracking of timed trajectories in a new way. The technique is applied to a dual arm manipulator performing a bi-manual task. We present experimental validation of the approach, including comparisons between simulations and real experiments of a complex bimanual tracking task. We also show how to add force feedback to the framework, to account for modeling errors in the systems. We compare the results with and without feedback, and show how the resulting trajectory is modified to achieve the prescribed interaction forces.
Energy Expenditure during Non-Traditional Physical Activities

Sell K, Clocksin BD, Spierer D, Ghigiarelli J. Energy Expenditure during Non-Traditional Physical Activities. JEPonline 2011;14(3):101112. The purpose of this study was to compare the physical demands of a climbing activity (Prusik climbing) to Nintendo Wii boxing and brisk walking. Twenty-four college students (24 ± 4 years; 175.4 ± 8.6 cm; 78.9 ± 17.4 kg) attended four separate laboratory sessions: (a) 30 min of brisk walking; (b) maximal oxygen consumption (VO2 max) test; (c) 30 min of Nintendo Wii boxing; and (d) 30 min of Prusik climbing. During the walking, boxing, and Prusik climbing, heart rate (HR), rating of perceived exertion (RPE), oxygen consumption (VO2) and respiratory exchange ratio (RER) were recorded, from which average METs, total and average energy expenditure (TEE30 and Aver-EE1.0), and percentage of VO2 reserve (%VO2R) were determined. Prusik climbing generated significantly higher average VO2, %VO2R, HR, RPE, METs, TEE30, and Aver-EE1.0 compared to brisk walking and Wii boxing (P<0.05). Prusik climbing may provide an appealing alternative to traditional exercise programs for meeting current physical activity recommendations.
Structural Analysis of Complex Wind Turbine Blades: Flexo- Torsional Vibrational Modes

Limitations in the current blade technology constitute a technological barrier that needs to be broken in order to continue the improvement in wind-energy cost. Blade manufacturing is mostly based on composite laminates, which is labor-intensive and requires highly-quali‐ fied manpower. It constitutes a bottleneck to turbine upscaling that reflects into the increas‐ ing share of the cost of the rotor, within the total cost of the turbine, as turbine size increases. Figure 1 shows a compilation of data by NREL-DOE [26] on the proportional cost of each subsystem for different sizes of wind-turbines, where the systematic increase of the rotor cost share is clearly reflected.
Cooperative Global Localization in Multi-Robot System

With the development of robotic technology, the application areas of robots have been greatly widened. The robots may serve as assistants (Elena et al., 2004), rescuers (Robert & Arvin, 2003) and explorers (Schenker et al., 2003). In many cases a multi-robot system has to be used, since many tasks cannot be completed with a single robot and multi-robot system can finish the tasks much more efficiently. As in a single robot system, knowing their relative positions and their global positions in the environment are the preconditions for performing tasks and coordination. Since a robot can determine the location of another robot relative to its own when they see each other, both robots can refine their internal beliefs based on the other robot’s estimate. In this way cooperative localization of multiple robots can greatly improve the localization precision and efficiency (Fox et al., 2000; Trawny et al., 2009). An area that has received some attentions in the single-robot case and very little attention in the multi-robot case is active localization (Fox et al., 1998). In active localization, the robot(s) may actively choose actions so as to aid in localization. Active localization has the potential to increase the speed and accuracy of localization further. In this chapter a mechanism of making robots coordinate their action actively during localization is proposed. In order to determine the exploration strategy, the ability to stably track multi-hypotheses of the robot’s own position and his partners’ positions is very important in active localization. However using traditional particle filters for localization tends to produce premature convergence, i.e. the hypothesis represented by particle filters converge to a small area of the state space with high likelihood too quickly. To overcome this problem a new version of particle filters termed co-evolution particle filters (CEPF) is proposed. Another problem of using particle filters in multi-robot localization system is the communication problem. When several robots want to share their estimates they have to transmit a large set of samples from one robot to another, so a great bandwidth is needed. To solve this problem the reduced set density estimator (RSDE) (Girolami & Chao, 2003) is used to estimate the density over robots’ pose, so that only a small sub-set of the original samples should be transmitted between robots, which can reduce the communication data considerably.

Testing Stereoscopic Vision in Robot Teleguide

The aim of this chapter is to provide a focused guideline on how to test virtual reality (VR) systems used in robot teleoperation. The guideline is demonstrated based on a real experiment. The goal of this experiment is to test the characteristics and the advantages of a telerobotic system based on video transmission and stereoscopic viewing. The experimentation design follows a systematic approach that relies on identification of a number of key parameters and a usability evaluation designed according them. Two different 3D visualization facilities are considered for evaluating performance on systems with different characteristics, cost and application context. The results of the experiments are expected to provide insight into stereoscopic robot teleguide, and to understand on what system, and to what extent, is stereo vision beneficial.
Signaling Pathways Altered During the Metastatic Progression of Melanoma

that appears to act as a metastamiR in melanoma is the miR-214. MiR-214 expression was evaluated in the poorly metastatic lineage A375 and in its highly metastat‐ ic variant cell lines, originated from several passages in vivo . It was seen an upregulation of miR-214 in the highly metastatic melanoma cells lines in comparison with the parental one. Beyond that, the overexpression of miR-214 in a metastatic lineage that expressed intermediate levels of this miRNA resulted in a higher number of lung metastases than the control in a metastasis formation assay in vivo . In addition, miR-214 silencing in a highly metastatic lineage, which expressed high levels of this miRNA, caused a significantly reduction of lung metastases formation. Furthermore, as primary tumor growth was not influenced by miR-214, these results indicate miR-214 as a metastamiR with an important role in the melanoma progression [119].
Girls, Women and Substance Use

here is considerable evidence to support women-specific approaches to prevention, treatment, harm reduction, research and policy on substance use and addiction. There is a clear need to understand the differences in substance use between males and females, as well as among diverse groups of women and girls. The BC Centre of Excellence for Women’s Health (BCCEWH) and the Canadian Centre on Substance Abuse (CCSA) have developed this information resource together to summarize the ways in which substance use and addiction differ for girls and women, and the implications of those differences for policy, research, systems and services. With the signing of a Memorandum of Agreement in 2004, BCCEWH and CCSA have formalized an opportunity to enhance their respective roles in promoting health and reducing the harms for girls and women associated with their use of alcohol, tobacco and other drugs. What patterns of use are common for girls and women?
The role of associations in regional innovation systems

This paper addressed the need for research regarding the role of associations in innovation systems. As defined here, the term association embraces not only organisations like business associations, but all actors who associate to pursue joint objectives and positively influence their (regional) innovation system. In the innovation system's perspective, these associations perform intermediary functions. As the relevant activities are often initiated by individuals acting in specific environments and circumstances, we need to consider not only the level of the organisation (i.e. meso level), but also the macro level of the innovation system and the micro level of individuals. Against the background of economic and social theory, intrinsic motivations have therefore also been discussed. External conditions, like the mode of governance and the logic of influence are also relevant as these define the framework conditions. Over time, associations may evolve in line with changes in the environment and internal developments. This evolution can be regarded as a life cycle which is specific to each association. Different types of associations and their specific functions have been mentioned using the example of Germany. While each of the listed associations can be regarded as an individual case, we can also assume that there are certain traits which are shared by all of them. Thus, we proposed four hypotheses addressing the macro level, i.e. the level of the regional innovation system, the meso level, i.e. the level of the association, and the micro level, which considers the motivations of individuals. We further proposed an empirical concept to be applied to study the role of associations in innovation systems.
AHP‐Aided Evaluation of Logistic and Transport Solutions in a Seaport

The chapter reports on the application of the analytic hierarchy process (AHP) to a strategic decision in the transport sector, concerning the reconfiguration of the railway infrastructure of the seaport of Trieste. The proposed solutions should not only solve some technical and operational problems of the terminal, but they could allow the port to be included in the Trans‐European Network‐Transport Programme (TEN‐T), promoted by the European Union and aimed to develop the Trans‐European Net‐ works of Transport. Accordingly, the selection of the solution with the most promis‐ ing potential to satisfy the goals of the TEN‐T policy is a fundamental stage of the project. The case study is an actual AHP application to an evaluation process concerning a pre‐ feasibility study of strategic solutions in the logistics and transport fields. Some practical aspects regarding the application of the AHP and the building of the model, when several stakeholders are involved in the decision process, are highlighted and discussed.
On the Coherence of Higher-order Beliefs

Abstract in Undetermined Let us by first-order beliefs mean beliefs about the world, such as the belief that it will rain tomorrow, and by second-order beliefs let us mean beliefs about the reliability of first-order, belief-forming processes. In formal epistemology, coherence has been studied, with much ingenuity and precision, for sets of first-order beliefs. However, to the best of our knowledge, sets including second-order beliefs have not yet received serious attention in that literature. In informal epistemology, by contrast, sets of the latter kind play an important role in some respectable coherence theories of knowledge and justification. In this paper, we extend the formal treatment of coherence to second-order beliefs. Our main conclusion is that while extending the framework to second-order beliefs sheds doubt on the generality of the notorious impossibility results for coherentism, another problem crops up that might be no less damaging to the coherentist project: facts of coherence turn out to be epistemically accessible only to agents who have a good deal of insight into matters external to their own belief states.

The VLT LBG Redshift Survey - III. The clustering and dynamics of Lyman-break galaxies at z ~ 3

We present a catalogue of 2135 galaxy redshifts from the VLT LBG Redshift Survey (VLRS), a spectroscopic survey of z approximate to 3 galaxies in wide fields centred on background quasi-stellar objects. We have used deep optical imaging to select galaxies via the Lyman-break technique. Spectroscopy of the Lyman-break galaxies (LBGs) was then made using the Very Large Telescope (VLT) Visible Multi-Object Spectrograph (VIMOS) instrument, giving a mean redshift of z = 2.79. We analyse the clustering properties of the VLRS sample and also of the VLRS sample combined with the smaller area Keck-based survey of Steidel et al. From the semiprojected correlation function, w(p)(sigma), for the VLRS and combined surveys, we find that the results are well fit with a single power-law model, with clustering scale lengths of r(0) = 3.46 +/- 0.41 and 3.83 +/- 0.24 h(-1) Mpc, respectively. We note that the corresponding combined xi (r) slope is flatter than for local galaxies at gamma = 1.5-1.6 rather than gamma = 1.8. This flat slope is confirmed by the z-space correlation function, xi (s), and in the range 10 <s <100 h(-1) Mpc the VLRS shows an approximate to 2.5 sigma excess over the Lambda cold dark matter (Lambda CDM) linear prediction. This excess may be consistent with recent evidence for non-Gaussianity in clustering results at z approximate to 1. We then analyse the LBG z-space distortions using the 2D correlation function, xi (sigma, pi), finding for the combined sample a large-scale infall parameter of beta = 0.38 +/- 0.19 and a velocity dispersion of root w(z)(2) = 420(-160)(+140) km s-1. Based on our measured beta, we are able to determine the gravitational growth rate, finding a value of f(z = 3) = 0.99 +/- 0.50 (or f sigma(8) = 0.26 +/- 0.13), which is the highest redshift measurement of the growth rate via galaxy clustering and is consistent with Lambda CDM. Finally, we constrain the mean halo mass for the LBG population, finding that the VLRS and combined sample suggest mean halo masses of log(M-DM/M-circle dot) = 11.57 +/- 0.15 and 11.73 +/- 0.07, respectively.
Reducing Disproportional Discipline Referrals For African American Male Students At The Elementary Level

The National Center for Education Statistics [NCES] (2010) documents that most teachers in urban/city schools are White, female teachers. Differences in communication styles, culture, and involvement can have a negative impact on the educational experiences of minority and male students. However, there are White, female teachers who can demonstrate the ability to engage their students that have helped to reduce the disciplinary disparity in their schools. This study focuses on answering the overarching question, what dispositional characteristics/qualities, instructional methods, environmental parameters and classroom management techniques do White, female teachers perceive contribute to lower classroom disciplinary referrals for African American males in the elementary classroom? To answer this question, three separate interviews were conducted with each participant utilizing an established protocol, two classroom observations were conducted of each participant utilizing an observation protocol and reviewing three years of discipline data for each participant. Findings revealed students need to be actively involved in the educational process. Settings need to be structured and procedures established that allow students to demonstrate independence. Teachers need to engage parents by providing opportunities for communication through various means. There needs to be a common vocabulary that transcends cultural differences and personal bias and experiences. Lastly, teacher preparation programs need to
From the Germanic to the Soviet Accounting System (History of Czechoslovak Accounting after the World War Two)

The development of accounting in Czechoslovakia after the World War II was influenced by political and economic changes of that time. Firstly, it is a subject to tradition, and then also the political order. It results in the transition from the Germanic type of accounting to the Soviet model of accounting, i.e. from the Singular System of Business Accounting to Book-Keeping Evidence under the National-Economic Evidence. Although the Soviet accounting system is by some formal characteristics based on the Anglo-Saxon model of accounting, it was unable to operate efficiently in terms of collectivist economies of the communist regime, i.e. neither in Czechoslovakia.
Architecture Modeling at the Preliminary Design of Real-Time Systems

Rate Monotonic Analysis (RMA) is based on analytical approaches to verify real-time constraints based on scheduling theory. Considering RMA, we proposed an architectural style that allows designers to reason in great detail about system’s behavior. The notation and semantics supported by the style eases the application of analytical tools to evaluate real-time properties, as soon as preliminary design phase. The style was applied in data acquisition and supervisory systems monitoring industrial processes.
Growing Uses of 2A in Plant Biotechnology

The combination, ‘pyramiding’ or ‘stacking’ of multiple genes in plants is a fundamental aspect of modern plant research and biotechnology. The most widely adopted stacked traits (herbi‐ cide tolerance and insect protection) provide growers with benefits of increased crop yield, simplified management of weed control and reduced insecticide use. The global acreage of stacked traits or more precisely genetically modified organisms bearing stacked traits is expected to increase rapidly in the near future, with the introduction of nutritional and/or industrial traits to satisfy the needs of consumers and producers [1]. Several approaches have been used to stack multiple genes into plant genomes and then to coordinate expression [2-4]. Stacking approaches include sexual crossing between plants carrying distinct transgenes [5,6], sequential re-transformation [7], and single-plasmid [8] or multiple-plasmid co-transforma‐ tion [9]. These strategies, however, suffer from the inherent weakness that co-expression of the heterologous proteins is unreliable.

mpact of RGD micro-patterns on cell adhesion

In order to avoid the problems related to biomaterial use (inflammation, infections, aseptic loosening, etc.), a new approach consisting of associating the material and autologous cells before implantation is being developed, thus requiring a perfect cooperation between the material’s surface and the cell. To improve cell adhesion to biomaterials, a suitable method is to functionalize their surface by proadhesive ligand grafting. The aim of this study was to covalently graft RGD containing peptides onto a poly-(ethylene terephthalate) surface in well-defined microstructures in order to control MC3T3 cell adhesion. We followed two different routes for obtaining micro-patterned materials: (1) a photoablation technique using an excimer laser and (2) a photolithography process. The resulting patterns were characterized by optical microscopy, scanning electron microscopy, optical profilometry and high reso-
