Weather radar networks are indispensable tools for forecasting and disaster prevention in industrialized countries. However, they are far less common in the countries of South America, which frequently suffer from an underdeveloped network of meteorological stations. To address this problem in southern Ecuador, this article presents a novel radar network using cost-effective, single-polarization, X-band technology: the RadarNet-Sur. The RadarNet-Sur network is based on three scanning X-band weather radar units that cover approximately 87,000 km2 of southern Ecuador. Several instruments, including five optical disdrometers and two vertically aligned K-band Doppler radar profilers, are used to properly (inter) calibrate the radars. Radar signal processing is a major issue in the high mountains of Ecuador because cost-effective radar technologies typically lack Doppler capabilities. Thus, special procedures were developed for clutter detection and beam blockage correction by integrating ground-based and satelliteborne measurements. To demonstrate practical applications, a map of areas frequently affected by intense rainfall is presented, based on a time series of one radar that has been in operation since 2002. Such information is of vital importance to, for example, infrastructure management because rain-driven landslides are a major issue for road maintenance and safety throughout Ecuador. The presented case study of exceptionally strong rain events during the recent El Niño in March 2015 highlights the system’s practicality in weather forecasting related to disaster management. For the first time, RadarNet-Sur warrants a spatial-explicit observation of El Niño-related heavy precipitation in a transect from the coast to the highlands in a spatial resolution of 500 m.
Interactions between the MJO, Aerosols, and Convection over the Central Indian Ocean

Published: October 2016

This study examines covariability of boundary layer cloud condensation nuclei (CCN) concentrations [estimated using the GEOS 3D chemical transport model (GEOS-Chem)], convective clouds, precipitation, and lightning observed over the central equatorial Indian Ocean (CIO). Three distinct Madden–Julian oscillation (MJO) episodes were observed during the recent Dynamics of the MJO (DYNAMO; 2011/12) field campaign. Coherent relationships between CCN, rainfall, and lightning are apparent in time series from DYNAMO and more lightning located north of the equator is noted, compared to south of the equator. More-polluted environments north of the equator contained deep convective clouds that had stronger radar reflectivities (~2–3 dB) in the mixed-phase region (5–10-km altitude) compared to south of the equator. Following discussion of the MJO episodes that occurred during DYNAMO, 22 cycles of the MJO observed during boreal cold seasons in the years 2004–11 are examined with the aid of TRMM satellite observations. Climatological results suggest that horizontal transport of continental aerosols from proximal landmasses by the large-scale circulation after active MJO convection reinforces the meridional gradient of CCN concentrations in the CIO. Satellite observations depicted comparable aggregate cold cloud feature area in both regions in similar thermodynamic environments, leading to the suggestion that higher CCN concentrations north of the equator act to invigorate convection. Direct comparisons of convective intensity metrics to CCN support the aerosol hypothesis; however, in line with previous studies, it is acknowledged that conditional instability, vertical wind shear, and environmental moisture can modulate the initial development of deep convection over the CIO during select phases of the MJO.
What Makes an Annular Mode “Annular”?
Authors: Gerber Edwin P. , Thompson David W. J.
Published: October 2016

Annular patterns with a high degree of zonal symmetry play a prominent role in the natural variability of the atmospheric circulation and its response to external forcing. But despite their apparent importance for understanding climate variability, the processes that give rise to their marked zonally symmetric components remain largely unclear. Here the authors use simple stochastic models in conjunction with an atmospheric model and observational analyses to explore the conditions under which annular patterns arise from empirical orthogonal function (EOF) analysis of the flow. The results indicate that annular patterns arise not only from zonally coherent fluctuations in the circulation (i.e., “dynamical annularity”) but also from zonally symmetric statistics of the circulation in the absence of zonally coherent fluctuations (i.e., “statistical annularity”). It is argued that the distinction between dynamical and statistical annular patterns derived from EOF analysis can be inferred from the associated variance spectrum: larger differences in the variance explained by an annular EOF and successive EOFs generally indicate underlying dynamical annularity. The authors provide a simple recipe for assessing the conditions that give rise to annular EOFs of the circulation. When applied to numerical models, the recipe indicates dynamical annularity in parameter regimes with strong feedbacks between eddies and the mean flow. When applied to observations, the recipe indicates that annular EOFs generally derive from statistical annularity of the flow in the midlatitude troposphere but from dynamical annularity in both the stratosphere and the mid–high-latitude Southern Hemisphere troposphere.
Seasonal Differences in Precipitation Sensitivity to Soil Moisture in Bangladesh and Surrounding Regions
Authors: Sugimoto Shiori , Takahashi Hiroshi G.
Published: October 2016

Precipitation sensitivity to soil moisture and its seasonal and diurnal changes are investigated in Bangladesh and surrounding regions using a regional climate model with a 5-km grid spacing. In the control experiment, soil moisture is calculated by a land surface scheme, and simulated accuracy of seasonal and diurnal variations in precipitation intensity and frequency is capable of assessing the soil moisture impact on precipitation. In sensitivity experiments with wetter land surfaces, daytime precipitation intensity decreases over the southern plains for both the premonsoon and mature monsoon seasons because of the weakening of surface heating and vertical mixing in the planetary boundary layer (PBL). Weakened vertical turbulent flux of moisture reduces condensation heating and upward motion in the mid- and upper troposphere, which suppresses development of convective precipitation. The simulated precipitation intensity response to soil moisture suggests that land surface wetness contributes to the seasonal contrast in observed precipitation intensity (i.e., stronger in the premonsoon than the mature monsoon seasons). Meanwhile, the precipitation frequency response to soil moisture varies with season and by region. Over the southern plains in the wet land surface experiments, daytime precipitation frequency decreases (increases) during the premonsoon (mature monsoon) season compared with the dry land surface experiments, as influenced by seasonal differences in relative humidity and the condensation process in the lower troposphere. Around the northern mountainous area, higher soil moisture increases precipitation frequency regardless of season because of additional water vapor supply from the ground and frequent orographic precipitation forced by the mountainous topography.
Homogenization of Daily Temperature Data
Authors: Hewaarachchi Anuradha P. , Li Yingbo , Lund Robert , Rennie Jared
Published: October 2016

This paper develops a method for homogenizing daily temperature series. While daily temperatures are statistically more complex than annual or monthly temperatures, techniques and computational methods have been accumulating that can now model and analyze all salient statistical characteristics of daily temperature series. The goal here is to combine these techniques in an efficient manner for multiple changepoint identification in daily series; computational speed is critical as a century of daily data has over 36 500 data points. The method developed here takes into account 1) metadata, 2) reference series, 3) seasonal cycles, and 4) autocorrelation. Autocorrelation is especially important: ignoring it can degrade changepoint techniques, and sample autocorrelations of day-to-day temperature anomalies are often as large as 0.7. While daily homogenization is not conducted as commonly as monthly or annual homogenization, daily analyses provide greater detection precision as they are roughly 30 times as long as monthly records. For example, it is relatively easy to detect two changepoints less than two years apart with daily data, but virtually impossible to flag these in corresponding annually averaged data. The developed methods are shown to work in simulation studies and applied in the analysis of 46 years of daily temperatures from South Haven, Michigan.
A Tiling Approach to Represent Subgrid Snow Variability in Coupled Land Surface–Atmosphere Models
Authors: Aas Kjetil Schanke , Gisnås Kjersti , Westermann Sebastian , Berntsen Terje Koren
Published: October 2016

A mosaic approach to represent subgrid snow variation in a coupled atmosphere–land surface model (WRF–Noah) is introduced and tested. Solid precipitation is scaled in 10 subgrid tiles based on precalculated snow distributions, giving a consistent, explicit representation of variable snow cover and snow depth on subgrid scales. The method is tested in the Weather Research and Forecasting (WRF) Model for southern Norway at 3-km grid spacing, using the subgrid tiling for areas above the tree line. At a validation site in Finse, the modeled transition time from full snow cover to snow-free ground is increased from a few days with the default snow cover fraction formulation to more than 2 months with the tiling approach, which agrees with in situ observations from both digital camera images and surface temperature loggers. This in turn reduces a cold bias at this site by more than 2°C during the first half of July, with the noontime bias reduced from −5° to −1°C. The improved representation of subgrid snow variation also reduces a cold bias found in the reference simulation on regional scales by up to 0.8°C and increases surface energy fluxes (in particular the latent heat flux), and it resulted in up to 50% increase in monthly (June) precipitation in some of the most affected areas. By simulating individual soil properties for each tile, this approach also accounts for a number of secondary effects of uneven snow distribution resulting in different energy and moisture fluxes in different tiles also after the snow has disappeared.
Wind and Current Forcing Combine to Drive Strong Upwelling in the Agulhas Current
Authors: Leber Greta M. , Beal Lisa M. , Elipot Shane
Published: October 2016

Strong upwelling events inshore of the Agulhas Current close to 33.5°S are investigated. These events are important to the exchange of shelf and slope waters, potentially enhancing primary productivity and advecting larvae offshore. Using hydrographic observations, this study shows that a wind-driven upwelling event and a current-driven upwelling event can each advect central waters more than 130 m upward, resulting in a maximum 9°C cooling at 50-m depth over the continental shelf and surface cooling greater than 4°C. The authors use satellite data to assess the frequency and forcing mechanisms of similar cold events from January 2003 through December 2011, defining cold events as days when the sea surface temperature (SST) anomaly is significantly correlated with a local current or wind forcing. The authors identify 47 events with an average length of 2.2 days and SST anomaly of −1.6°C, corresponding to an average 13 days of surface cold events along the Agulhas Current front per year. This study uses combined EOF analysis to characterize these cold events based on four highly correlated forcing mechanisms: alongshore wind speed, wind stress curl, current meandering, and current speed over the slope. The authors find that meanders act in combination with upwelling-favorable winds to force the strongest cold events, while upwelling-favorable winds alone, possibly primed by Ekman veering, force weaker cold events. Most significantly, it is found that the frontal curvature of warm Agulhas Current meanders couples with the atmosphere to drive local wind stress curl anomalies that reinforce upwelling.
Cultures of gendered violence: An integrative review of measures of attitudinal support for violence against women
Authors: Powell Anastasia , Webster Kim
Published: October 2016

National and international research has repeatedly identified the specific gendered nature and context of women’s victimisation of violence, whereby women are disproportionately victims of sexual and partner violence and overwhelmingly at the hands of known male perpetrators. As such, violence against women warrants a targeted and substantial focus, within overall violence reduction and prevention efforts. In the Australian policy context, there is an emerging and influential focus on attitudes towards violence against women as key targets for primary prevention and as foci for monitoring progress in reducing this violence. The Australian National Community Attitudes Towards Violence Against Women Survey was established to estimate community-level understanding of and attitudes towards violence against women. It has arguably evolved into an important instrument both for monitoring shifts in Australians’ knowledge and attitudes, as well as for directing primary prevention efforts. The purpose of this article is to provide an integrative review in relation to one of the key dimensions of the national community attitudes survey: violence supportive attitudes (see Webster et al., 2014). Here, we seek to identify patterns in defining and measuring attitudes that support violence against women, as well as advance the field by offering recommendations for progressing the measurement of violence supportive attitudes in Australia in the future.
Well-controlled silver nanowire/graphene hybrid from full solution process
Authors: Park Jeong Eon , Suh Dong Hack
Published: October 2016

The surface of a one-dimensional silver nanowire was covered with amphiphilic materials, N-(2-aminoethyl)-3a-hydroxy-5b-cholan-24-amide, and patched with two-dimensional graphene to form individually controlled hybrid. Graphene was prepared from ultrasonic in o-dichlorobenzene without any additives. As N-(2-aminoethyl)-3a-hydroxy-5b-cholan-24-amide between silver nanowires and graphene tightly held each other, silver nanowire was individually covered with graphene without introducing ultrasonic power, the necessary process to evenly mix silver nanowires and graphene but lead to damage and oxidize silver nanowires. Although the quality of graphene was inferior, the properties of hybrid were superior compared with pristine silver nanowire/graphene except introducing N-(2-aminoethyl)-3a-hydroxy-5b-cholan-24-amide. All processes to form the hybrid were carried out in solution. Therefore, this makes the processes less expensive and more useful and opens up opportunities for the mass production for conductive materials.
British and US Anticommunism Between the World Wars
Authors: Olmsted Kathryn
Published: October 2016

This article examines the espionage and propaganda networks established by former professional spies and other anticommunist activists in the interwar period in the United States of America and the United Kingdom. In both countries, conservatives responded to the growing power of labor in politics by creating and funding private groups to coordinate spying operations on union activists and political radicals. These British and US spies drew upon the resources of the government while evading democratic controls. The anti-labor groups also spread anti-radical propaganda, but the counter-subversive texts in the UK tended to highlight the economic threats posed by radicalism, while those in the USA appealed to more visceral fears. The leaders of these anti-labur networks established a transnational alliance with their fellow anticommunists across the Atlantic decades before the beginning of the Cold War.
A Narrative of Two Preservice Music Teachers With Visual Impairment
Authors: Parker Elizabeth Cassidy , Draves Tami J.
Published: October 2016

The purpose of this narrative inquiry was to re-story the student teaching experience of two preservice music education majors who are visually impaired or blind. While music education scholars have devoted attention to P–12 students with disabilities, research with preservice music teachers with impairments is seemingly nonexistent. Using a transformative paradigm and social model of disability as lenses, we retell participants’ experiences across three commonplaces of narrative inquiry: sociality, temporality, and place. Participants told their student teaching stories through various field texts, including interviews, journals, emails, and informal conversations. Three particular issues were highlighted strongly within their narratives: accessible music, reliance on others, and individuals’ attitudes. Issues of what constitutes effective teaching, teacher identity construction, and preparedness for working with individuals with disabilities also emerged. Multiple avenues are suggested for practice, research, and policy in music, teacher education, and teachers with disabilities.
All-Cause Mortality Among US Veterans of the Persian Gulf War
Authors: Barth Shannon K. , Kang Han K. , Bullman Tim
Published: October 2016

Objective:

We determined cause-specific mortality prevalence and risks of Gulf War deployed and nondeployed veterans to determine if deployed veterans were at greater risk than nondeployed veterans for death overall or because of certain diseases or conditions up to 13 years after conflict subsided.

Methods:

Follow-up began when the veteran left the Gulf War theater or May 1, 1991, and ended on the date of death or December 31, 2004. We studied 621   901 veterans who served in the 1990-1991 Persian Gulf War and 746   247 veterans who served but were not deployed during the Gulf War. We used Cox proportional hazard models to calculate rate ratios adjusted for age at entry to follow-up, length of follow-up, race, sex, branch of service, and military unit. We compared the mortality of (1) Gulf War veterans with non–Gulf War veterans and (2) Gulf War army veterans potentially exposed to nerve agents at Khamisiyah in March 1991 with those not exposed. We compared standardized mortality ratios of deployed and nondeployed Gulf War veterans with the US population.

Results:

Male Gulf War veterans had a lower risk of mortality than male non–Gulf War veterans (adjusted rate ratio [aRR] = 0.97; 95% confidence interval [CI], 0.95-0.99), and female Gulf War veterans had a higher risk of mortality than female non–Gulf War veterans (aRR = 1.15; 95% CI, 1.03-1.28). Khamisiyah-exposed Gulf War army veterans had >3 times the risk of mortality from cirrhosis of the liver than nonexposed army Gulf War veterans (aRR = 3.73; 95% CI, 1.64-8.48). Compared with the US population, female Gulf War veterans had a 60% higher risk of suicide and male Gulf War veterans had a lower risk of suicide (standardized mortality ratio = 0.84; 95% CI, 0.80-0.88).

Conclusion:

The vital status and mortality risk of Gulf War and non–Gulf War veterans should continue to be investigated.
New Medicaid Enrollees See Health and Social Benefits in Pennsylvania’s Expansion

Published: October 2016

Understanding how new Medicaid enrollees are approaching their own health and health care in the shifting health care landscape of the Affordable Care Act has implications for future outreach and enrollment efforts, as well as service planning for this population. The objective of this study was to explore the health care experiences and expectations of new Medicaid expansion beneficiaries in the immediate post-enrollment period. We conducted semistructured, qualitative interviews with a random sample of 40 adults in Philadelphia who had completed an application for Medicaid through a comprehensive benefits organization after January 1, 2015, when the Medicaid expansion in Pennsylvania took effect. We conducted an inductive, applied thematic analysis of interview transcripts. The new Medicaid beneficiaries described especially high levels of pent-up demand for care. Dental care was a far more pressing and motivating concern than medical care. Preventive services were also frequently mentioned. Participants anticipated that insurance would reduce both stress and financial strain and improve their experience in the health care system by raising their social standing. Participants highly valued the support of telephone application counselors in the Medicaid enrollment process to overcome bureaucratic obstacles they had encountered in the past. Dental care and preventive services appear to be high priorities for new Medicaid enrollees. Telephone outreach and enrollment support services can be an effective way to overcome past experiences with administrative barriers.
Vietnamese in Poland: How does ethnicity affect immigrant entrepreneurship?
Authors: Andrejuk Katarzyna
Published: October 2016

The article examines the business activities of Vietnamese immigrants in Poland. Against the backdrop of a highly differentiated Vietnamese population in Poland, this study found that the ethnicity of immigrants can serve as a resource (especially as a source of values, such as diligence and intra-group solidarity) and as a strategy for promoting success in business activities. However, negative stereotypes and state policies toward immigrant self-employment can limit the market access of certain groups. Findings from the study demonstrate that ethnic entrepreneurship in a post-communist country may be subject to the same processes as in other European states and the US.
Enabling smart objects discovery via constructing hypergraphs of heterogeneous IoT interactions
Authors: Jung Jooik , Chun Sejin , Jin Xiongnan , Lee Kyong-Ho
Published: October 2016

Recent advances in the Internet of Things (IoT) have led to the rise of a new paradigm: Social Internet of Things (SIoT). However, the new paradigm, as inspired by the idea that smart objects will soon have a certain degree of social consciousness, is still in its infant state for several reasons. Most of the related works are far from embracing the social aspects of smart objects and the dynamicity of inter-object social relations. Furthermore, there is yet to be a coherent structure for organising and managing IoT objects that elicit social-like features. To fully understand how and to what extent these objects mimic the behaviours of humans, we first model SIoT by scrutinising the distinct characteristics and structural facets of human-centric social networks. To elaborate, we describe the process of profiling the IoT objects that become social and classify various inter-object social relationships. Afterwards, a novel discovery mechanism, which utilises our hypergraph-based overlay network model, is proposed. To test the feasibility of the proposed approach, we have performed several experiments on our smart home automation demo box built with various sensors and actuators.
The Anthropo-scene: A guide for the perplexed
Authors: Lorimer Jamie
Published: October 2016

The scientific proposal that the Earth has entered a new epoch as a result of human activities – the Anthropocene – has catalysed a flurry of intellectual activity. I introduce and review the rich, inchoate and multi-disciplinary diversity of this Anthropo-scene. I identify five ways in which the concept of the Anthropocene has been mobilized: scientific question, intellectual zeitgeist, ideological provocation, new ontologies and science fiction. This typology offers an analytical framework for parsing this diversity, for understanding the interactions between different ways of thinking in the Anthropo-scene, and thus for comprehending elements of its particular and peculiar sociabilities. Here I deploy this framework to situate Earth Systems Science within the Anthropo-scene, exploring both the status afforded science in discussions of this new epoch, and the various ways in which the other means of engaging with the concept come to shape the conduct, content and politics of this scientific enquiry. In conclusion the paper reflects on the potential of the Anthropocene for new modes of academic praxis.
Evaluating the Student–Teacher Relationship Scale in Italian Young Children: An Exploratory Structural Equation Modeling Approach
Authors: Sette Stefania , Zuffianò Antonio , Lucidi Fabio , Laghi Fiorenzo , Lonigro Antonia , Baumgartner Emma
Published: October 2016

The study analyzed the factorial and concurrent validity of the Student–Teacher Relationship Scale (STRS) using an exploratory structural equation modeling (ESEM) approach. Participants were 368 Italian children aged 3 to 6 ( M = 4.60, SD = 0.98). The three-factor ESEM solution fit the data better than the classical confirmatory factor analysis (CFA) model and the measurement invariance of the scale was confirmed across sex and age (3-4 vs. 5-6 years) groups. The concurrent validity of the STRS was investigated within the ESEM approach using children’s social behaviors as validity criteria. Findings supported the goodness of ESEM over CFA and attested to the validity of the STRS to understanding the teacher–child relationship quality in young children.
The Too-Much-Precision Effect
Authors: Loschelder David D. , Friese Malte , Schaerer Michael , Galinsky Adam D.
Published: October 2016

Past research has suggested a fundamental principle of price precision: The more precise an opening price, the more it anchors counteroffers. The present research challenges this principle by demonstrating a too-much-precision effect. Five experiments (involving 1,320 experts and amateurs in real-estate, jewelry, car, and human-resources negotiations) showed that increasing the precision of an opening offer had positive linear effects for amateurs but inverted-U-shaped effects for experts. Anchor precision backfired because experts saw too much precision as reflecting a lack of competence. This negative effect held unless first movers gave rationales that boosted experts’ perception of their competence. Statistical mediation and experimental moderation established the critical role of competence attributions. This research disentangles competing theoretical accounts (attribution of competence vs. scale granularity) and qualifies two putative truisms: that anchors affect experts and amateurs equally, and that more precise prices are linearly more potent anchors. The results refine current theoretical understanding of anchoring and have significant implications for everyday life.
The energy consumption and health hazards of mobile phones
Authors: Velmurugan Manivannan S
Published: October 2016

Mobile phones are universally popular due to their convenience. Mobile phones solve problems and offer new channels of communication by using a device small enough to fit into one hand. On the other hand, mobile phones may be harmful to the environment and health, and waste disposal problems may be associated with their use. This study discusses the risks associated with mobile phone use and addresses the options to rectify those issues in the longer term.

Practitioners and researchers alike face the challenge that different sources report inconsistent information regarding child maltreatment. The present study capitalizes on concordance and discordance between different sources and probes applicability of a multisource approach to data from three perspectives on maltreatment—Child Protection Services (CPS) records, caregivers, and children. The sample comprised 686 participants in early childhood (3- to 8-year-olds; n = 275) or late childhood/adolescence (9- to 16-year-olds; n = 411), 161 from two CPS sites and 525 from the community oversampled for psychosocial risk. We established three components within a factor-analytic approach: the shared variance between sources on presence of maltreatment (convergence), nonshared variance resulting from the child’s own perspective, and the caregiver versus CPS perspective. The shared variance between sources was the strongest predictor of caregiver- and self-reported child symptoms. Child perspective and caregiver versus CPS perspective mainly added predictive strength of symptoms in late childhood/adolescence over and above convergence in the case of emotional maltreatment, lack of supervision, and physical abuse. By contrast, convergence almost fully accounted for child symptoms for failure to provide. Our results suggest consistent information from different sources reporting on maltreatment is, on average, the best indicator of child risk.

Published: October 2016

The elastic properties of a spherical heterogeneous structure with isotropic periodic components is analyzed and a methodology is developed using the two-scale asymptotic homogenization method (AHM) and spherical assemblage model (SAM). The effective coefficients are obtained via AHM for two different composites: (a) composite with perfect contact between two layers distributed periodically along the radial axis; and (b) considering a thin elastic interphase between the layers (intermediate layer) distributed periodically along the radial axis under perfect contact. As a result, the derived overall properties via AHM for homogeneous spherical structure have transversely isotropic behavior. Consequently, the homogenized problem is solved. Using SAM, the analytical exact solutions for appropriate boundary value problems are provided for different number of layers for the cases (a) and (b) in the spherical composite. The numerical results for the displacements, radial and circumferential stresses for both methods are compared considering a spherical composite material loaded by an inside pressure with the two cases of contact conditions between the layers (a) and (b).
Process Evaluation of a Retreat for Scholars in the First Cohort: The NIH Mixed Methods Research Training Program for the Health Sciences

Published: October 2016

The Mixed Methods Research Training Program for the Health Sciences aims to enlarge the national pool of trained investigators in mixed methods and improve the quality of grant applications to the National Institutes of Health. Selected scholars are assigned a consulting team, participate in webinars, and attend an annual “retreat” focused on learning mixed methods through application to their research. Our article summarizes the process evaluation of the retreat. Scholars identified strengths in small interactive groups to discuss individual projects and the opportunity to apply learning. Scholars wanted further opportunity to discuss individual projects, understanding interventions and mixed methods, and finding collaborators. Our findings will be useful to leaders developing workshops or similar programs at the faculty level.
New public management and the ‘business’ of policing organised crime in Australia
Authors: Mann Monique
Published: October 2016

The globalisation of new public management (NPM) across OECD countries had a profound impact on the administration and management of policing policy and practice. The ideologies of NPM were enthusiastically embraced in Australia in response to high-level corruption with mixed results. This article draws on interviews with senior Australian federal police to explore the policing of organised crime in the context of NPM. Emerging themes concerned the requirement to make the ‘business case’ for resources on the basis of strategic intelligence, recognition of the complexities associated with performance measurement and institutional competition as agencies vie for limited public resources. This article questions the discursive practices of NPM policing and raises questions about notions of ‘accountability’ and ‘transparency’ for effective police approaches to organised crime.
Implications of Visuospatial Skills and Executive Functions for Learning Mathematics
Authors: Kim Helyn , Cameron Claire E.
Published: October 2016

The purpose of this article is to review the literature and apply a developmental neuroscience perspective in investigating the role of two interrelated cognitive processes—executive functions (EFs) and visuospatial (VS) skills—which have been empirically and theoretically linked to children’s mathematics achievement. To illustrate, we provide evidence of the importance of EFs and VS skills for mathematics learning by examining and comparing the distinct cognitive profiles of individuals with autism spectrum disorder and Williams syndrome. By simultaneously considering two cognitive processes that are implicated in mathematics, we offer insight into the underlying mechanisms by which EFs and VS skills support children’s learning and acquisition of mathematical skills, as well as how neuroscience research may successfully inform educational practice.

Own-wage labor supply elasticities: variation across time and estimation methods
Authors: Bargain Olivier , Peichl Andreas
Published: October 2016

There is a huge variation in the size of labor supply elasticities in the literature, which hampers policy analysis. While recent studies show that preference heterogeneity across countries explains little of this variation, we focus on two other important features: observation period and estimation method. We start with a thorough survey of existing evidence for both Western Europe and the USA, over a long period and from different empirical approaches. Then, our meta-analysis attempts to disentangle the role of time changes and estimation methods. We highlight the key role of time changes, documenting the incredible fall in labor supply elasticities since the 1980s not only for the USA but also in the EU. In contrast, we find no compelling evidence that the choice of estimation method explains variation in elasticity estimates. From our analysis, we derive important guidelines for policy simulations.
MG-63 osteoblast-like cell proliferation on auxetic PLGA scaffold with mechanical stimulation for bone tissue regeneration
Authors: Choi Hong Jin , Lee Jun Jae , Park Yeong Jun , Shin Jung-Woog , Sung Hak-Joon , Shin Ji Won , Wu Yanru , Kim Jeong Koo
Published: October 2016

Background

Auxetic scaffolds (experimental) was fabricated by using poly(D, L-lactic-co-glycolic acid), 50:50, (PLGA) for effective bone cell proliferation with mechanical stimulation.

Methods

Negative Poisson’s ratio in scaffold, 3-directional volumetric compression was applied during the scaffold fabrication at adequate temperature (60 °C). The pore size of scaffold ranged between 355 and 400 μm.

Results

The porous morphology of the prepared auxetic scaffolds had shown partially concave and dent shapes in SEM image as expected. The lowest Poisson’s ratios of experimental group was −0.07 at 60 °C/10 min. Compressive strength of experimental group was shown about 3.12 times higher than control group (conventional scaffold) in dry state at 25 °C. The compressive strengths of both groups were tended to be decreased dramatically in wet state compared to in dry state. However, compressive strengths of experimental group were higher 3.08 times and 1.88 times in EtOH/PBS (25 °C) and EtOH/PBS/DMEM (37 °C) than control group in wet state, respectively. Degradation rate of the scaffolds showed about 16 % weight loss in 5 weeks. In cell attachment test, experimental group showed 1.46 times higher cell proliferation than control group at 1-day with compressive stimulation. In 3-day culture, the experimental group showed 1.32 times higher than control group. However, there was no significant difference in cell proliferation in 5-day cultivation.

Conclusion

Overall, negative Poisson’s ratio scaffolds with static mechanical stimulation could affect the cell proliferation at initial cultivation time.
Lipid-based surface engineering of PLGA nanoparticles for drug and gene delivery applications

Published: October 2016

The use of poly(lactic-co-glycolic acid) (PLGA)-based nanocarriers presents several major challenges, including their synthetic hydrophobic surface, low transfection efficiency, short circulation half-life, and nonspecific tissue distribution. Numerous engineering strategies have been employed to overcome these problems, with lipid-based surface functionalization of PLGA nanoparticles (NPs) showing promising results in the development of PLGA-based clinical nanomedicines. Surface engineering with different lipids enhances the target specificity of the carrier and improves its physicochemical properties as well as NP-cell associations, such as cellular membrane permeability, immune responses, and long circulation half-life in vivo.

Authors: Brame Cynthia J.
Published: October 2016

Educational videos have become an important part of higher education, providing an important content-delivery tool in many flipped, blended, and online classes. Effective use of video as an educational tool is enhanced when instructors consider three elements: how to manage cognitive load of the video; how to maximize student engagement with the video; and how to promote active learning from the video. This essay reviews literature relevant to each of these principles and suggests practical ways instructors can use these principles when using video as an educational tool.

Olfactory epithelium (OE) has a lifelong capacity for neurogenesis due to the presence of basal stem cells. Despite the ability to generate short-term cultures, the successful in vitro expansion of purified stem cells from adult OE has not been reported. We sought to establish expansion-competent OE stem cell cultures to facilitate further study of the mechanisms and cell populations important in OE renewal. Successful cultures were prepared using adult mouse basal cells selected for expression of c-KIT. We show that c-KIT signaling regulates self-renewal capacity and prevents neurodifferentiation in culture. Inhibition of TGFβ family signaling, a known negative regulator of embryonic basal cells, is also necessary for maintenance of the proliferative, undifferentiated state in vitro. Characterizing successful cultures, we identified expression of BMI1 and other Polycomb proteins not previously identified in olfactory basal cells but known to be essential for self-renewal in other stem cell populations. Inducible fate mapping demonstrates that BMI1 is expressed in vivo by multipotent OE progenitors, validating our culture model. These findings provide mechanistic insights into the renewal and potency of olfactory stem cells.
The role and regulation of Rab40b–Tks5 complex during invadopodia formation and cancer cell invasion

Invadopodia formation and extracellular matrix degradation are key events during cancer cell invasion, yet little is known about mechanisms mediating these processes. Here, we report that Rab40b plays a key role in mediating invadopodia function during breast cancer cell invasion. We also identify Tks5 (also known as SH3PXD2A), a known Src kinase substrate, as a new Rab40b effector protein and show that Tks5 functions as a tether that mediates Rab40b-dependent targeting of transport vesicles containing MMP2 and MMP9 to the extending invadopodia. Importantly, we also demonstrate that Rab40b and Tks5 levels are regulated by known tumor suppressor microRNA miR-204. This is the first study that identifies a new Rab40b–Tks5- and miR-204-dependent invadopodia transport pathway that regulates MMP2 and MMP9 secretion, and extracellular matrix remodeling during cancer progression.
Firm Size Distortions and the Productivity Distribution: Evidence from France
Authors: Garicano Luis , Lelarge Claire , Van Reenen John
Published: October 2016

We show how size-contingent laws can be used to identify the equilibrium and welfare effects of labor regulation. Our framework incorporates such regulations into the Lucas (1978) model and applies it to France where many labor laws start to bind on firms with 50 or more employees. Using population data on firms between 1995 and 2007, we structurally estimate the key parameters of our model to construct counterfactual size, productivity, and welfare distributions. We find that the cost of these regulations is equivalent to that of a 2.3 percent variable tax on labor. In our baseline case with French levels of partial real wage inflexibility, welfare costs of the regulations are 3.4 percent of GDP ( falling to 1.3 percent if real wages were perfectly flexible downward). The main losers from the regulation are workers—and to a lesser extent, large firms—and the main winners are small firms. (JEL L11, L51, J8)
Taxing Top CEO Incomes
Authors: Ales Laurence , Sleet Christopher
Published: October 2016

We use a firm-CEO assignment framework to model the market for CEO effective labor. In the model’s equilibrium, more talented CEOs match with and supply more effort to larger firms. Taxation of CEO incomes affects the equilibrium pricing of CEO effective labor and, hence, spills over and affects firm profits. Absent the ability to tax profits or a direct concern for firm owners, a standard prescription for high marginal income taxes emerges. However, given such an ability or concern, the optimal marginal tax rates are much lower. (JEL D31, H21, M12)
Does Welfare Inhibit Success? The Long-Term Effects of Removing Low-Income Youth from the Disability Rolls
Authors: Deshpande Manasi
Published: October 2016

I estimate the effects of removing low-income youth with disabilities from Supplemental Security Income (SSI) on their earnings and income in adulthood. Using a regression discontinuity design based on a 1996 policy change in age 18 medical reviews, I find that youth who are removed from SSI at age 18 recover one-third of the lost SSI cash income in earnings. SSI youth who are removed and stay off SSI earn on average $4,400 annually, and they lose $76,000 in present discounted observed income over the 16 years following removal relative to those who do not receive a review.

Whither Game Theory? Towards a Theory of Learning in Games
Authors: Fudenberg Drew , Levine David K.
Published: October 2016

Game theory has been a huge success in economics. Many important questions have been answered, and game theoretic methods are now central to much economic investigation. We suggest areas where further advances are important, and argue that models of learning are a promising route for improving and widening game theory's predictive power while preserving the successes of game theory where it already works well. We emphasize in particular the need for better understanding of the speed with which learning takes place.

Features and Perspectives of Legal Regulation of Lobbying in Russia
Authors: Спектор Екатерина , Spyektor YEkatyerina
Published: October 2016

In this paper the author revealed various approaches of lobbying legal regulation overseas and its legal regulation problems in Russia through the prism of analysis of a number of draft laws regulating the institute of lobbying and law-enforcement practice. Despite the ambiguous attitude toward this institution existing in the society the author proves the necessity of its legal interpretation and legislative recognition. Institutionalization of lobbying activity and the regulation of a transparent mechanism for the coordination of political, economic and other groups’ interests in the process of legislative drafting are the most acute and relates to one of the most important anti-corruption initiatives.
