Published: May 2016

The combination of in-cylinder thermal environment and fuel ignition properties plays a critical role in the homogeneous charge compression ignition engine combustion process. The properties of fuels available in the automotive market vary considerably and display different auto-ignition behaviors for the same intake charge conditions. Thus, in order for homogeneous charge compression ignition (HCCI) technology to become practically viable, it is necessary to characterize the impact of differences in fuel properties as a source of ignition/combustion variability. To quantify the differences, 15 gasolines composed of blends made from refinery streams were investigated in a single-cylinder homogeneous charge compression ignition engine. The properties of the refinery stream blends were varied according to research octane number, sensitivity (S = research octane number − motor octane number) and volumetric contents of aromatics and olefins. Nine fuels contained 10% ethanol by volume, and six more were blended with 20% ethanol. Pure ethanol (E100) and an un-oxygenated baseline fuel (RD3-87) were included too. For each fuel, a sweep of intake temperature at a consistent load and engine speed was conducted, and the combustion phasing given by the crank angle of 50% mass fraction burned was tracked to assess the sensitivity of auto-ignition to fuel chemical kinetics. The experimental results provided a wealth of information for predicting the HCCI combustion phasing from the given properties of a fuel. In this study, the original octane index correlation proposed by Kalghatgi based solely on fuel research octane number and motor octane number was found to be insufficient for characterizing homogeneous charge compression ignition combustion of refinery stream fuels. A new correlation was developed for estimation of auto-ignition properties of practical fuels in the typical HCCI engine. Fuel composition, captured by terms indicating the fraction of aromatics, olefins, saturates and ethanol, was added to generate the following formula: [Formula: see text]. The results indicate a significantly improved estimation of combustion phasing for gasoline fuels of varying chemical composition under low-temperature combustion conditions. Quantitative findings of this investigation and the new octane index correlation can be used for designing robust HCCI control strategies, capable of handling the wide spectrum of fuel chemical compositions found in pump gasoline.
Sonic affects and the production of space: ‘Music by handle’ and the politics of street music in Victorian London
Authors: Simpson Paul
Published: May 2016

This article examines the affective capacities of sound and its role in the on-going production of social spaces. More specifically, the article seeks to understand the situated nature of sound’s affectivity within particular social-political-material contexts or circumstances. This is developed through a discussion of an empirical case study related to the history of street music: the ‘street music debates’ of Victorian London. The interrelation here of the sounds street musicians made, the broader urban soundscape of the time, who played street music and who it was that found themselves listening to this music demonstrate clearly the situated affective capacities of street music. From this, the article advocates an understanding of the role of sound in the on-going production of social spaces based upon a reciprocal mediation between ‘macropolitical’ matters related to identity and other social formations and the ‘micropolitics’ of the affects that such sound and music bring to bear for those exposed to it.

Published: May 2016

Background. Culturally appropriate efforts are needed to increase sexually transmitted disease (STD) testing and care among Black and Latino sexual-minority youth, who are at high risk for STDs. Get Yourself Tested, a national testing campaign, has demonstrated success among youth, but it has yet to be assessed for relevance or impact among this population. Method. This effort included (1) formative and materials-testing research through focus groups; (2) adaptation of existing Get Yourself Tested campaign materials to be more inclusive of Black and Latino sexual-minority youth; (3) a 3-month campaign in four venues of New York City, promoting STD testing at events and through mobile testing and online and social media platforms; (4) process evaluation of outreach activities; and (5) an outcome evaluation of testing at select campaign venues, using a preexperimental design. Results. During the 3-month campaign period, the number of STD tests conducted at select campaign venues increased from a comparable 3-month baseline period. Although testing uptake through mobile vans remained low in absolute numbers, the van drew a high-prevalence sample, with positivity rates of 26.9% for chlamydia and 11.5% for gonorrhea. This article documents the process and lessons learned from adapting and implementing a local campaign for Black and Latino sexual-minority youth.

Published: May 2016

Socioeconomic status (SES) is a fundamental cause of ill health, but an understudied determinant of health for gay, bisexual, and other men who have sex with men (MSM). Surprisingly, few studies have examined the relations between poverty and depression among young MSM. The aims of this study were to determine the reliability and validity of an 18-item Family Resource Scale (FRS) as a measure of SES among YMSM and examine the relations between SES and depression, while taking into account factors associated with resilience or risk for poor mental health. Reliability of the SES scale was determined with Cronbach’s alpha. Validity was assessed with factor analysis and bivariable comparisons with other SES measures. Multiple logistic regression was used to determine the relations between depressive symptomology (via the Beck Depression Inventory–II), SES, and gay-related psychosocial variables. In this racially/ethnically diverse sample (mean age = 21.8 years, 37.3% Hispanic/Latino, 30.5% White, 14.9% Black, and 17.0% other race/ethnicity), 70.8% reported incomes ≤ $10,000 and the mean FRS score was 4.1 ( SD = 0.9, range 0-5). The FRS demonstrated reliability (α = .91) and criterion and construct validity. The Beck Depression Inventory–II rated 17.6% with depressive symptomology. Higher FRS scores were associated with a lower odds of depression (adjusted odds ratio = 0.58; 95% confidence interval = 0.46-0.74) in logistic regression models controlling for gay community affinity and internalized homophobia. This diverse sample of YMSM in New York City reported substantial financial hardship and those who were more gay-identified had fewer material resources. Fewer material resources and internalized homophobia were both associated with higher odds of depression.

Published: May 2016

With the development of automatic control and communication technology, communication-based train control system is adopted by more and more urban mass transit system to automatically supervise the train speed to follow a desired trajectory. Taking reliability, availability, maintainability, and safety into consideration, 2 × 2-out-of-2 safety computer platform is usually utilized as the hardware platform of safety-critical subsystem in communication-based train control. To enhance the safety integrity level of safety computer platform, safety-related logics have to be verified before integrating them into practical systems. Therefore, a significant problem of developing safety computer platform is how to guarantee that system behaviors will satisfy the function requirements as well as responding to external events and processes within the limit of right time. Based on the qualitative and quantitative analysis of function and timing characteristics, this article introduces a formal modeling and verification approach for this real-time system. In the proposed method, timed automata network model for 2 × 2-out-of-2 safety computer platform is built, and system requirements are specified and formalized as computation tree logic properties which can be verified by UPPAAL model checker.

Published: May 2016

In this article, an ad hoc microsat constellation based on secondary launches is proposed to meet the demands for the constellation characteristics. Research on its structural design and characteristics is carried out. First, constellation characteristic indices are proposed, including the coverage characteristics, health stability, and aggregation degrees, in order to analyze the feasibility of ad hoc microsat constellations. Then, several characteristic indices of ad hoc microsat constellations are compared with those of the traditional constellation, “Walker.” Research results show that ad hoc micro satellite constellation based on secondary launching not only meets the requirements of the traditional constellations but also saves the launch costs, a feature which has important practical significance.
Analysis of the response of a reinforced concrete shear wall structure during earthquakes using the transfer matrix method of multibody systems
Authors: Ding Jianguo , Huang Huijia , Zhuang Wei , Wang Chunwei
Published: May 2016

Although reinforced concrete shear wall structures are widely used in high-rise buildings, the methods used to analyze the seismic response of such a structure during an earthquake generally have low calculation efficiencies. In this article, the transfer matrix method of multibody systems is first established as a mechanical model of a regular reinforced concrete shear wall structure with both bifurcated and closed transfer paths to analyze the seismic responses of structures. By separating the shear wall legs, establishing a state vector relationship between the two endpoints of the coupling beams, and combining all state vectors of the inputs or outputs of each shear wall leg, the total transfer between shear wall legs is realized, and the overall transfer equation and overall transfer matrix of a shear wall structure are obtained. Applying the transfer matrix method of multibody systems, a 15-story shear wall structure is used as an engineering example to analyze seismic responses for frequent and rare earthquakes using MATLAB software. The findings show that the transfer matrix method of multibody systems provides similar results to ANSYS but that the transfer matrix method of multibody systems greatly increases calculation efficiency while maintaining accuracy.

Published: May 2016

Background:

The study aimed to assess the influence of the calcification of the ascending aorta on surgical mortality, postoperative stroke, and completeness of coronary revascularization in patients undergoing off-pump coronary artery bypass grafting with graft strategy tailored to its calcification severity.

Methods and results:

We examined the clinical records of 726 patients who underwent off-pump coronary artery bypass grafting. The age at operation was 71 ± 8 years. Calcification of the ascending aorta was graded as none–mild (less than spotty) in 668 (92.0%), moderate (<1/4 of circumference) in 26 (3.6%), and severe (>1/4) in 32 (4.4%) by preoperative non-contrast computed tomography. There were no significant differences in the number of distal anastomoses per patient among the three groups (3.3 ± 1.1, 2.9 ± 1.0, and 3.0 ± 0.9, respectively; p = 0.85). Graft strategy was tailored for each patient. Proximal anastomosis with partial clamp was used in 43.8%, 7.7%, and 3.1%, respectively (p < 0.001), while anastomotic devices were used in 6.8%, 30.1%, and 28.1%, respectively (p < 0.001). Other patients had aortic no-touch technique. There were four hospital deaths in the none–mild group (0.6%, p = 0.85). Stroke occurred in 1 (0.1%) patient, an aortic no-touch technique patient with none–mild calcification. Complete revascularization was not possible in 1 (0.1%) patient in the severe calcification group. Patency of saphenous vein graft of distal anastomosis was not different among groups.

Conclusion:

Influence of the calcification of the ascending aorta was minimized by tailoring graft strategy to calcification severity. It can practically abolish postoperative stroke while maintaining coronary revascularization success rates.

Published: May 2016

Purpose:

The purpose of this study is to assess postmarketing safety and tolerability of Stribild (elvitegravir [EVG]/cobicistat [COBI]/tenofovir disoproxil fumarate [TDF]/emtricitabine [FTC]).

Methods:

A retrospective, pharmacoepidemiologic study in 2 outpatient HIV clinics in the Southeast United States was conducted among adults receiving EVG/COBI/TDF/FTC. We evaluated incidence and treatment-related adverse events, including change in serum creatinine (SCr).

Results:

Patients were primarily treatment experienced (n = 173, 60%), African American (n = 210, 73%), and males (n = 187, 65%). One hundred ninety-five (68%) patients had any increase in SCr, and 65 (23%) had an increase of ≥0.3 mg/dL. Mean SCr change from baseline to peak was 0.2 mg/dL. Being treatment experienced (odds ratio [OR] = 2.21, 95% confidence interval [CI]: 1.12-4.38) was associated with SCr ≥0.3 mg/dL, while body mass index ≥30 kg/m2 (OR = 0.41, 95% CI: 0.18-0.93) was protective. Twenty (7%) patients discontinued therapy, 3 due to acute kidney injury.

Conclusion:

Our results demonstrate limited adverse events and low discontinuation rates associated with EVG/COBI/TDF/FTC.

Authors: Mehran Nima , Williams Phillip N. , Keller Robert A. , Khalil Lafi S. , Lombardo Stephen J. , Kharrazi F. Daniel
Published: May 2016

Background:

Anterior cruciate ligament (ACL) injuries are significant injuries in elite-level basketball players. In-game statistical performance after ACL reconstruction has been demonstrated; however, few studies have reviewed functional performance in National Basketball Association (NBA)–caliber athletes after ACL reconstruction.

Purpose:

To compare NBA Combine performance of athletes after ACL reconstruction with an age-, size-, and position-matched control group of players with no previous reported knee injury requiring surgery. We hypothesized that there is no difference between the 2 groups in functional performance.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

A total of 1092 NBA-caliber players who participated in the NBA Combine between 2000 and 2015 were reviewed. Twenty-one athletes were identified as having primary ACL reconstruction prior to participation in the combine. This study group was compared with an age-, size-, and position-matched control group in objective functional performance testing, including the shuttle run test, lane agility test, three-quarter court sprint, vertical jump (no step), and maximum vertical jump (running start).

Results:

With regard to quickness and agility, both ACL-reconstructed athletes and controls scored an average of 11.5 seconds in the lane agility test and 3.1 seconds in the shuttle run test ( P = .745 and .346, respectively). Speed and acceleration was measured by the three-quarter court sprint, in which both the study group and the control group averaged 3.3 seconds ( P = .516). In the maximum vertical jump, which demonstrates an athlete’s jumping ability with a running start, the ACL reconstruction group had an average height of 33.6 inches while the controls averaged 33.9 inches ( P = .548). In the standing vertical jump, the ACL reconstruction group averaged 28.2 inches while the control group averaged 29.2 inches ( P = .067).

Conclusion:

In athletes who are able to return to sport and compete at a high level such as the NBA Combine, there is no significant difference in any combine performance test between players who have had primary ACL reconstruction compared with an age-, size-, and position-matched control group.

Clinical Relevance:

Athletes with previous ACL reconstruction who are able to return to high-level professional basketball have equivalent performance measures with regard to speed, quickness, and jumping ability as those athletes who have not undergone knee surgery.

Asthma management guidelines recommend adding a long-acting β2-agonist (LABA) or increasing the dose of inhaled corticosteroid (ICS) as step-up therapy for patients with uncontrolled asthma on ICS monotherapy. However, it is uncertain which option works best, which ICS particle size is most effective, and whether LABA should be administered by separate or combination inhalers.

This historical, matched cohort study compared asthma-related outcomes for patients (aged 12–80 years) prescribed step-up therapy as a ≥50% extrafine ICS dose increase or add-on LABA,viaeither a separate inhaler or a fine-particle ICS/LABA fixed-dose combination (FDC) inhaler. Risk-domain asthma control was the primary end-point in comparisons of cohorts matched for asthma severity and control during the baseline year.

After 1:2 cohort matching, the increased extrafine ICSversusseparate ICS+LABA cohorts included 3232 and 6464 patients, respectively, and the fine-particle ICS/LABA FDCversusseparate ICS+LABA cohorts included 7529 and 15 058 patients, respectively (overall mean age 42 years; 61–62% females). Over one outcome year, adjusted OR (95% CI) for achieving asthma control were 1.25 (1.13–1.38) for increased ICSversusseparate ICS+LABA and 1.06 (1.05–1.09) for ICS/LABA FDCversusseparate ICS+LABA.

For patients with asthma, increased dose of extrafine-particle ICS, or add-on LABAviaICS/LABA combination inhaler, is associated with significantly better outcomes than ICS+LABAviaseparate inhalers.
Discovering causal interactions using Bayesian network scoring and information gain
Authors: Zeng Zexian , Jiang Xia , Neapolitan Richard
Published: May 2016

Background

The problem of learning causal influences from data has recently attracted much attention. Standard statistical methods can have difficulty learning discrete causes, which interacting to affect a target, because the assumptions in these methods often do not model discrete causal relationships well. An important task then is to learn such interactions from data. Motivated by the problem of learning epistatic interactions from datasets developed in genome-wide association studies (GWAS), researchers conceived new methods for learning discrete interactions. However, many of these methods do not differentiate a model representing a true interaction from a model representing non-interacting causes with strong individual affects. The recent algorithm MBS-IGain addresses this difficulty by using Bayesian network learning and information gain to discover interactions from high-dimensional datasets. However, MBS-IGain requires marginal effects to detect interactions containing more than two causes. If the dataset is not high-dimensional, we can avoid this shortcoming by doing an exhaustive search.

Results

We develop Exhaustive-IGain, which is like MBS-IGain but does an exhaustive search. We compare the performance of Exhaustive-IGain to MBS-IGain using low-dimensional simulated datasets based on interactions with marginal effects and ones based on interactions without marginal effects. Their performance is similar on the datasets based on marginal effects. However, Exhaustive-IGain compellingly outperforms MBS-IGain on the datasets based on 3 and 4-cause interactions without marginal effects. We apply Exhaustive-IGain to investigate how clinical variables interact to affect breast cancer survival, and obtain results that agree with judgements of a breast cancer oncologist.

Conclusions

We conclude that the combined use of information gain and Bayesian network scoring enables us to discover higher order interactions with no marginal effects if we perform an exhaustive search. We further conclude that Exhaustive-IGain can be effective when applied to real data.
Crowdsourcing the nodulation gene network discovery environment
Authors: Li Yupeng , Jackson Scott A.
Published: May 2016

Background

The Legumes (Fabaceae) are an economically and ecologically important group of plant species with the conspicuous capacity for symbiotic nitrogen fixation in root nodules, specialized plant organs containing symbiotic microbes. With the aim of understanding the underlying molecular mechanisms leading to nodulation, many efforts are underway to identify nodulation-related genes and determine how these genes interact with each other. In order to accurately and efficiently reconstruct nodulation gene network, a crowdsourcing platform, CrowdNodNet, was created.

Results

The platform implements the jQuery and vis.js JavaScript libraries, so that users are able to interactively visualize and edit the gene network, and easily access the information about the network, e.g. gene lists, gene interactions and gene functional annotations. In addition, all the gene information is written on MediaWiki pages, enabling users to edit and contribute to the network curation.

Conclusions

Utilizing the continuously updated, collaboratively written, and community-reviewed Wikipedia model, the platform could, in a short time, become a comprehensive knowledge base of nodulation-related pathways. The platform could also be used for other biological processes, and thus has great potential for integrating and advancing our understanding of the functional genomics and systems biology of any process for any species. The platform is available at http://crowd.bioops.info/, and the source code can be openly accessed at https://github.com/bioops/crowdnodnet under MIT License.
Spain: from massive immigration to vast emigration?
Authors: Izquierdo Mario , Jimeno Juan F. , Lacuesta Aitor
Published: May 2016

Large immigration flows during the 1995–2007 period increased the weight of foreigners living in Spain to 12 % of the total population. The rapid increase in unemployment associated with the Great Recession and the subsequent European debt crisis, substantially changed migration flows, so that, from the beginning of the 2010s, Spain experienced positive net outflows. In this paper, we take on three tasks. First, we show that sensitivity of migration flows to unemployment is similar between Spaniards born in Spain and foreigners that entered in Spain during the last 20 years. Second, we estimate the importance of past network effects of foreigners and the recent network effects of Spaniards in shaping these migration flows. Finally, we will use these estimations to conjecture that the rapid creation of networks of Spaniards abroad might keep their emigration rates growing, thus counterbalancing the effects of outflows due to the recent fall in the unemployment rate.
What’s the point? The role of punctuation in realising information structure in written English
Authors: Moore Nick
Published: May 2016

The main claim of this paper is that punctuation marks, in conjunction with spaces between words, function to provide visual rather than auditory cues for information structure in written English.Information structureis defined here as dividing the flow of discourse into units, each containing a newsworthy element, and in contrast to the Systemic Functional systems ofReferenceandTheme. A model of how these three systems interact is further supported by evidence from the historical development of reading and modern studies of the process of fluent silent reading. Reading silently does not require physical articulation and so written text is constrained by the saccading eye rather than the need to draw breath. The silent reader uses punctuation marks as a guide in a saccade to focus on the end of a clause which provides a non-arbitrary location for New information.

In search of inhospitable knowledge
Authors: Skokic Vlatka , Lynch Paul , Morrison Alison
Published: May 2016

The aim of this article is to discuss the key issues that have had significant influence on a Ph.D. research student’s journey from positivism to interpretivism and the subsequent impact on the research methodology adopted. This journey is illustrated by briefly analysing and reflecting upon the nature of relevant accumulated knowledge in the fields of hospitality, tourism and entrepreneurship fields; critically analysing the impact of the social setting on entrepreneurial behaviours and attitude; and reflecting upon how the two previous points influence researcher behaviour and methodological design. Drawing upon research undertaken within the Dalmatia region of Croatia, a former socialist country, the contextual focus is on small hotel owners within the hospitality industry. The article is loosely framed within a hospitality analytical lens and furthers debate on the nature of academic hospitality (Phipps and Barnett 2007) as well as proposing steps to welcome inhospitable knowledge. This article charts moments in the intellectual journey from positivism to interpretivism travelled by a Ph.D. researcher, who critically engaged in, analysed and deliberated upon the nature of accumulated knowledge associated with the field of her studies, where the power base of the knowledge resided, and consequential issues for advancement of thought. Further, as the journey progressed she reflected on the impact of the social setting of the key actors, which is the focus of her research, and ensuing implications for the research methodological design. In addition, the researcher had to engage in a critical self-reflection that required she transform herself from a ‘dispassionate scientist’ to an ‘insider participant’. The magnitude of this revelation is given context and profound meaning within the setting of Croatia, a former socialist country that has faced severe political, economic and social turmoil and transitions, including war. In making the transformation, the researcher had to engage with inhospitable knowledge from the point of view of her educational formation. In so doing, the article highlights the importance of the boundaries of hospitality and looking at both their construction and exploration beyond.

Published: May 2016

Nach einer kurzen Einführung in die Technologie der Papierherstellung und der Mengenentsäuerung werden zunächst die Entwicklungen auf dem Gebiet der Qualitätskontrolle aufgezeigt. Zurzeit sind der pH-Wert, die alkalische Reserve und ihre Verteilung die Hauptkriterien zur Bewertung des Behandlungserfolgs. Da diese destruktiven Messmethoden nicht an Originalobjekten erfolgen können, muss ein universell einsetzbares Testpapier definiert werden. Im Wesentlichen muss dieses Testpapier das Absorptionsverhalten eines Entsäuerungsreagenzes und dessen Reaktionen mit im Papier vorhandenen Säuren darstellen können. Passend dazu müssen entsprechende Messmethoden den Entsäuerungserfolg zweifelsfrei darstellen können. Mit der Kombination von geeignetem Testpapier und spezieller Celluloseanalyse wurde hier im Rahmen der ISO / TS 18344 ein neuer Weg beschritten.

Vector-valued holomorphic
and harmonic functions
Authors: Arendt Wolfgang
Published: May 2016

Holomorphic and harmonic functions with values in a Banach space are investigated. Following an
approach given in a joint article with Nikolski [4] it is shown that for bounded functions with values in a Banach
space it suffices that the composition with functionals in a separating subspace of the dual space be holomorphic to
deduce holomorphy. Another result is Vitali’s convergence theorem for holomorphic functions. The main novelty in
the article is to prove analogous results for harmonic functions with values in a Banach space.
Invertible and normal composition operators on the Hilbert Hardy space of a half–plane
Authors: Matache Valentin
Published: May 2016

Operators on function spaces of form Cɸf = f ∘ ɸ, where ɸ is a fixed map are called composition operators with symbol ɸ. We study such operators acting on the Hilbert Hardy space over the right half-plane and characterize the situations when they are invertible, Fredholm, unitary, and Hermitian. We determine the normal composition operators with inner, respectively with Möbius symbol. In select cases, we calculate their spectra, essential spectra, and numerical ranges.
Optimization of Facility Layout of Tank farms using Genetic Algorithm and Fireball Scenario
Authors: Nabavi S.R. , Taghipour A.H. , Mohammadpour Gorji A.
Published: May 2016

In this study a novel approach is presented to optimize the layout of petrochemical units, considering the most likely scenario. To illustrate the method a real case study, exporting petrochemical tank farm (Esfahan petrochemical, Iran), was selected. Three objective functions like, piping cost, occupied land cost and human losses were combined and the total cost function was minimized. The required data for lethality function were obtained using simulation of different scenario by Phast software. A sigmoid function was fitted to the data which can estimate the lethality based on the distance from incident point. Genetic algorithm (GA) was used to minimize the total cost function. Due to vastness of searching area, more than one optimum layout was obtained. Finally, the optimum layouts were simulated with fire ball scenario and a good agreement was obtained between optimum points and simulated data.
In-situ coal seam and overburden permeability characterization combining downhole flow meter and temperature logs.
Authors: Busse Julia , Scheuermann Alexander , Bringemeier Detlef , Hossack Alex , Li Ling
Published: May 2016

The planning and design of any coal mine development requires among others a thorough investigation of the geological, geotechnical and hydrogeological subsurface conditions. As part of a coal mine exploration program we conducted heat pulse vertical flow meter testing. The flow data were combined with absolute and differential temperature logging data to gain information about the hydraulic characteristics of two different coal seams and their over- and interburden. For the strata that were localised based on geophysical logging data including density, gamma ray and resistivity hydraulic properties were quantified. We demonstrate that the temperature log response complements the flow meter log response. A coupling of both methods is therefore recommended to get an insight into the hydraulic conditions in a coal seam and its overburden.

Customer complaint behaviour, in response to service failures, has been shown to vary based on numerous factors, such as the nature of the service encounter, the setting, culture, gender and the presence of others. The gender-based study reported in this paper demonstrates the impact of two of these factors, i.e. the presence of others and gender, on the intent of Ecuadorian customers to voice their complaints about service failures in a restaurant setting. Employing a theoretical framework of impression management and cultural orientation, and with specific reference to Hofstede’s work on cultural differences, this study found that Ecuadorian customers were less likely to complain in the presence of other customers than when they were alone. Impression management and concern for others were shown to be more significant among women than men. Women were found to be more motivated to manage their public image and create positive impressions in other people’s minds, leading to less intent to complain in the presence of other customers than when they were alone. Male customers, on the other hand, exhibited less concern for others and did not show any significant difference in their complaint intentions, whether they were alone or in the presence of others.
Super-Learning of an Optimal Dynamic Treatment Rule
Authors: Luedtke Alexander R. , van der Laan Mark J.
Published: May 2016

We consider the estimation of an optimal dynamic two time-point treatment rule defined as the rule that maximizes the mean outcome under the dynamic treatment, where the candidate rules are restricted to depend only on a user-supplied subset of the baseline and intermediate covariates. This estimation problem is addressed in a statistical model for the data distribution that is nonparametric, beyond possible knowledge about the treatment and censoring mechanisms. We propose data adaptive estimators of this optimal dynamic regime which are defined by sequential loss-based learning under both the blip function and weighted classification frameworks. Rather than a priori selecting an estimation framework and algorithm, we propose combining estimators from both frameworks using a super-learning based cross-validation selector that seeks to minimize an appropriate cross-validated risk. The resulting selector is guaranteed to asymptotically perform as well as the best convex combination of candidate algorithms in terms of loss-based dissimilarity under conditions. We offer simulation results to support our theoretical findings.
In defense of the use of italic for latin binomial plant names
Authors: Teixeira da Silva Jaime A.
Published: May 2016

The author surveyed the instructions for authors in 110 botanical journals to assess how widely italic is used to represent the Latin binomial names of plants. Except for one journal that eliminated italic from the reference list, all of these journals published articles that used italic in the text and reference list for Latin binomial names of plants. However, in their instructions for authors only 48% of these journals explicitly requested the use of italic to denote the Latin binomial names of plants.
Spinless Particle in a Magnetic Field Under Minimal Length Scenario
Authors: Amirfakhrian S.M.
Published: May 2016

In this article, we studied the Klein–Gordon equation in a generalised uncertainty principle (GUP) framework which predicts a minimal uncertainty in position. We considered a spinless particle in this framework in the presence of a magnetic field, applied in the z-direction, which varies as

.

${1 \over {{x^2}}}.$

We found the energy eigenvalues of this system and also obtained the correspounding eigenfunctions, using the numerical method. When GUP parameter tends to zero, our solutions were in agreement with those obtained in the absence of GUP.

Reflexiones sobre la habitabilidad de la vivienda social: El Área Metropolitana Centro Occidente, Colombia
Authors: Orozco-Gómez Iris Eliana , Guzmán-López Samuel
Published: May 2016

La vivienda dirigida a las poblaciones de bajos ingresos económicos en el Área Metropolitana Centro Occidente, AMCO, no es entendida como un componente del hábitat y, por el contrario, es reducida a sus condiciones físico-espaciales. En esta medida es definida por los planificadores a partir de sus atributos endógenos que niegan otros factores inherentes a la dignidad humana, al acto de habitar y de apropiarse del ambiente como una condición de sustentabilidad que, como elementos de un sistema, no pueden ser analizados de forma aislada. La herramienta Sistema Ambiental Sectorial, SAS, de la Evaluación Ambiental Estratégica permitió representar sistémicamente la gestión habitacional metropolitana, el marco normativo, y las políticas y discursos dominantes con el fin de facilitar la comprensión de los elementos determinantes en el sistema habitacional en el AMCO dado el carácter compensador o descompensador de sus relaciones con los demás.

Construcción y transformación de masculinidades de los corteros de caña de azúcar del Valle del Cauca
Authors: Castro Muñoz Betsy Johana
Published: May 2016

Desde la perspectiva constructivista, la identidad se construye y reconstruye constantemente; es decir, que los seres humanos vamos sumando nuevos conocimientos a nuestra experiencia en el día a día, tejiendo relaciones en la interacción con el otro. En este proceso de aprendizaje y construcción continua tiene lugar no solo la interacción con el otro, sino también con el entorno social y cultural, que, para efectos de este contexto de investigación, se denominan las interacciones íntimas y cotidianas, que van construyendo al individuo como sujeto. De acuerdo con lo anterior, este artículo expone la construcción de masculinidades hegemónicas como uno de los rasgos de identidad cultural de los corteros de caña de azúcar, que se transforma tras su reubicación por accidente laboral. Esta reubicación laboral se traduce en detener el corte manual de caña y realizar otras labores que estén acordes con sus actuales capacidades físicas. Esta situación no solo tiene impacto en el cambio de labor, sino en sus interacciones íntimas y cotidianas. Como se presenta a lo largo del documento, la construcción de sus masculinidades está estrechamente asociada con la labor del corte manual de caña y con el contexto social y cultural en el cual tienen lugar su vida y esta labor. En ese sentido, se generan procesos de construcción de rasgos de identidad cultural, atravesados por prácticas masculinizantes que consolidan sus masculinidades hegemónicas. Tras la recopilación y el análisis de historias de vida, técnica utilizada en esta investigación de corte cualitativo, que parte de la experiencia de vida de los corteros de caña, logramos identificar que estos rasgos se transforman tras el accidente y la reubicación laborales. Sumado a lo anterior, logramos comprender que el sistema económico, como parte de la organización social de este grupo, es uno de los aspectos determinantes para la transformación de dichos rasgos, lo cual deriva en el cambio de dichas prácticas masculinizantes hacia el reconocimiento y el establecimiento de interacciones desde una perspectiva más horizontal con respecto a sus parejas y en general, a su grupo familiar.
Autoanálisis y aphrodisia: entre el disciplinamiento académico y la transgresión
Authors: Clavijo Poveda Jairo , Ramírez Rodríguez Andrés Felipe
Published: May 2016

Este artículo presenta un desarrollo metodológico autoanalítico que conscientemente buscó alejarse de la ilusión autobiográfica que se manifiesta en muchas autoetnografías, en las que la fuerza de la experiencia, el protagonismo del yo y, de la memoria propia, anulan cualquier posibilidad crítica. Siguiendo a Pierre Bourdieu y Bernard Lahire, se parte de la identificación del campo académico y de nuestra ubicación en él y, desde esta condición de posibilidad se adelanta la reflexión sobre el autoanálisis y se focaliza posteriormente en el tema de la aphrodisia. El rumbo que tomó la investigación llevó al terreno naturalizado de la formación de la masculinidad. El ejercicio apostó por la objetivación del indiferenciado sociólogo o antropólogo, que suele permanecer anónimo en cuanto sujeto social en el proceso de investigación de “el otro”. Se trató aquí de convertirse en “un otro”, y de observarse y examinarse con las herramientas sociológicas y antropológicas que utilizamos para estudiar a los demás “otros”. Más que una coautoría, este artículo resulta de la complicidad profesor y estudiante-investigador, en un ejercicio en el que esta relación académica cumple un papel fundamental en la regulación del análisis, en el manejo riguroso de los datos y en la escritura. El documento contiene dos partes: en la primera se plantean las cuestiones metodológicas, y en la segunda, el estudiante-investigador pone a prueba las herramientas sobre sí mismo. En este sentido, el primer nivel de la objetivación es el campo académico, desde el cual fue posible pensar la formación de una masculinidad heterodoxa, mediante el distanciamiento a priori de posiciones intelectualistas, ya que podrían terminar convirtiéndose en intelectualocentristas, como advierte el propio Bourdieu. Este marco permitió identificar la formación de la masculinidad particular como un habitus laminado entre diferentes fuerzas sociales, en el cual se desencadena el gusto por la transgresión de los espacios físicos, sociales y corporales como fuente central de la aphrodisia.
