Something ventured: Dangers and risk mitigation for the ordinary British Atlantic merchant ship, 1600–1800
Authors: Reid Phillip F
Published: June 2017

Using diverse sources, including archaeological evidence, this paper scrutinises the technology of the ordinary British Atlantic merchant ship, assessing continuity and change during the formation and development of the Atlantic empire (1600–1800). The paper argues that observable continuities and changes in rig, in hull design, and in defensive armament were responses to risks posed to owners, builders, and crews. I state that ‘risk mitigation’ was the main policy of the actors involved in the business, thus suggesting an innovative research path to assess decisions to innovate and decisions not to. This can thus contribute to a better understanding of Atlantic and technological history, as well as to an understanding of risk mitigation as a driving force in business and technology, beyond the more commonly used concept of disruptive innovations. Naturally, changes did take place, and investigate why that is helps us understand the continuity more fully, and ship technology more fully.
The Effect of Practice and Visual Feedback on Oral-Diadochokinetic Rates for Younger and Older Adults
Authors: Ben-David Boaz M. , Icht Michal
Published: June 2017

Assessments of oral-diadochokinetic rates are commonly performed to evaluate oral-motor skills. However, the appropriate administration protocol is not defined, and varies across therapists, clinics and laboratories. In three experiments and an auxiliary one, this study analyzes the effects of brief (motor) practice and visual feedback on the performance of 98 younger (20–40 years old) and 78 older adults (over 65) with the sequential motion rate (SMR) version. Overall rates were significantly faster for younger over older adults. Irrespective of age-group, averaged performance was significantly better on the second round, but the third round was found to be superfluous, across experiments and age-groups. Visual feedback (using a mirror) was found to be detrimental for younger adults, eliminating the advantage reaped from a practice round. For older adults, visual feedback did not alter the effect of a practice round. Sensory (visual) degradation is presented as a possible source for this age-related difference. We discuss these findings and suggest an administration protocol for younger and older adults with the SMR version, including a total of two rounds and no visual feedback.
HIV Testing and Positivity Patterns of Partners of HIV-Diagnosed People in Partner Services Programs, United States, 2013-2014
Authors: Song Wei , Mulatu Mesfin S. , Rorie Michele , Zhang Hui , Gilford John W.
Published: June 2017

Objective:

Human immunodeficiency virus (HIV) partner services are an integral part of comprehensive HIV prevention programs. We examined the patterns of HIV testing and positivity among partners of HIV-diagnosed people who participated in partner services programs in CDC-funded state and local health departments.

Methods:

We analyzed data on 21 484 partners submitted in 2013-2014 by 55 health departments. We conducted descriptive and multivariate analyses to examine patterns of HIV testing and positivity by demographic characteristics and geographic region.

Results:

Of 21 484 partners, 16 275 (75.8%) were tested for HIV; 4503 of 12 886 (34.9%) partners with test results were identified as newly HIV-positive. Compared with partners aged 13-24, partners aged 35-44 were less likely to be tested for HIV (adjusted odds ratio [aOR] = 0.86; 95% confidence interval [CI], 0.78-0.95) and more likely to be HIV-positive (aOR = 1.35; 95% CI, 1.20-1.52). Partners who were male (aOR = 0.89; 95% CI, 0.81-0.97) and non-Hispanic black (aOR = 0.68; 95% CI, 0.63-0.74) were less likely to be tested but more likely to be HIV-positive (male aOR = 1.81; 95% CI, 1.64-2.01; non-Hispanic black aOR = 1.52; 95% CI, 1.38-1.66) than partners who were female and non-Hispanic white, respectively. Partners in the South were more likely than partners in the Midwest to be tested for HIV (aOR = 1.56; 95% CI, 1.35-1.80) and to be HIV-positive (aOR = 2.18; 95% CI, 1.81-2.65).

Conclusions:

Partner services programs implemented by CDC-funded health departments are successful in providing HIV testing services and identifying previously undiagnosed HIV infections among partners of HIV-diagnosed people. Demographic and regional differences suggest the need to tailor these programs to address unique needs of the target populations.
When equity matters for marital stability
Authors: Bellani Daniela , Esping Andersen Gøsta , Pessin Léa
Published: June 2017

Comparing West Germany and the U.S., we analyze the association between equity—in terms of the relative gender division of paid and unpaid work hours—and the risk of marriage dissolution. Our aim is to identify under what conditions equity influences couple stability. We apply event-history analysis to marriage histories using data from the German Socio-Economic Panel for West Germany and the Panel Study of Income Dynamics for the U.S. for the period 1986–2009/10. For the U.S., we find that deviation from equity is particularly destabilizing when the wife underbenefits, especially when both partners’ paid work hours are similar. In West Germany, equity is less salient. Instead, we find that the male breadwinner model remains the single most stable couple arrangement.
Analytical SLAM without linearization
Authors: Tan Feng , Lohmiller Winfried , Slotine Jean-Jacques
Published: June 2017

This paper solves the classical problem of simultaneous localization and mapping (SLAM) in a fashion that avoids linearized approximations altogether. Based on the creation of virtual synthetic measurements, the algorithm uses a linear time-varying Kalman observer, bypassing errors and approximations brought by the linearization process in traditional extended Kalman filtering SLAM. Convergence rates of the algorithm are established using contraction analysis. Different combinations of sensor information can be exploited, such as bearing measurements, range measurements, optical flow, or time-to-contact. SLAM-DUNK, a more advanced version of the algorithm in global coordinates, exploits the conditional independence property of the SLAM problem, decoupling the covariance matrices between different landmarks and reducing computational complexity to O(n). As illustrated in simulations, the proposed algorithm can solve SLAM problems in both 2D and 3D scenarios with guaranteed convergence rates in a full nonlinear context.
Can I Ask for Help? The Relationship Among Incarcerated Males’ Sexual Orientation, Sexual Abuse History, and Perceptions of Rape in Prison
Authors: Ratkalkar Mina , Atkin-Plunk Cassandra A.
Published: June 2017

In 2003, Congress passed the Prison Rape Elimination Act (PREA). Although subsequent research to PREA has shed light on the prevalence and incidence of sexual violence in American prisons, few studies examine inmates’ perceptions of rape and safety from rape in prison. Even less is known about how inmates’ perceptions of rape influence mental health treatment–seeking behavior during incarceration. Using a sample of incarcerated men, this study adds to the limited body of research by examining the perceived fear of rape and mental health treatment–seeking behavior in two vulnerable prison populations—gay and bisexual inmates and inmates with a history of childhood sexual abuse. Compared with straight inmates, gay and bisexual inmates were approximately two times more likely to perceive that rape was a threat and three times more likely to voluntarily request mental health treatment in prison. Inmates with a history of childhood sexual abuse were over twice as likely to perceive the threat of rape and nearly four times more likely to request mental health treatment than inmates who did not report a history of childhood sexual abuse. Policy, practice implications, and recommendations for future research are discussed.
Stochastic rail life cycle cost maintenance modelling using Monte Carlo simulation
Authors: Vandoorne Rick , Gräbe Petrus J
Published: June 2017

The need for decision support systems to guide maintenance and renewal decisions for infrastructure is growing due to tighter budget requirements and the concurrent need to satisfy reliability, availability and safety requirements. The rail of the railway track is one of the most important components of the entire track structure and can significantly influence maintenance costs throughout the life cycle of the track. Estimation of life cycle cost is a popular decision support system. A calculated life cycle cost has inherent uncertainty associated with the reliability of the input data used in such a model. A stochastic life cycle cost model was developed for the rail of the railway track incorporating imperfect inspections. The model was implemented using Monte Carlo simulation in order to allow quantification of the associated uncertainty within the life cycle cost calculated. For a given set of conditions, an optimal renewal tonnage exists at which the rail should be renewed in order to minimise the mean life cycle cost. The optimal renewal tonnage and minimum attainable mean life cycle cost are dependent on the length of inspection interval, weld type used for maintenance as well as the cost of maintenance and inspection activities. It was found that the distribution of life cycle cost for a fixed renewal tonnage followed a log-normal probability distribution. The standard deviation of this distribution can be used as a metric to quantify uncertainty. Uncertainty increases with an increase in the length of inspection interval for a fixed rail renewal tonnage. With all other conditions fixed, it was found that the uncertainty in life cycle cost increases with an increase in the rail renewal tonnage. The relative contribution of uncertainty of the planned and unplanned maintenance costs towards the uncertainty in total life cycle cost was found to be dependent on the length of inspection interval.
A new self-tuning fuzzy controller for vibration of a flexible structure subjected to multi-frequency excitations
Authors: Fu Jie , Li Peidong , Choi Seung-Bok , Liao Guanyao , Wang Yuan , Yu Miao
Published: June 2017

This work proposes a new self-tuning fuzzy controller for vibration control of a flexible structure subjected to both single-frequency and multi-frequency excitations. A piezoelectric stack actuator is used to generate control force to attenuate vibrations in the resonant and non-resonant frequency ranges. As a first step, modal frequencies and modal shapes of the flexible beam structure are obtained via the finite element method, and these are verified through comparison with the measured values. Second, in order to attenuate multi-frequency vibration of the beam, a new fuzzy controller with self-tuning factors is proposed. This controller is independent of the structure model and very adaptive to variable excitations. Then, vibration control performances of the self-tuning fuzzy controller are experimentally investigated under two different excitation conditions: single-frequency and multi-frequency excitations. It is shown that vibration control capability of the proposed controller outperforms conventional fuzzy controller under two different excitation conditions. In addition, it is demonstrated by experimentally implementing the proposed self-tuning fuzzy controller that high performances of multi-frequency vibration control are successfully achieved in which both amplitude and frequency of sinusoidal excitations are varied.
First Impressions From Faces
Authors: Zebrowitz Leslie A.
Published: June 2017

Although cultural wisdom warns us not to judge a book by its cover, we seem unable to inhibit this tendency even though it can lead to inaccurate impressions of people’s psychological traits and has significant social consequences. One explanation for this paradox is that first impressions from faces reflect overgeneralizations of adaptive impressions of categories of people with structurally similar faces (including babies, familiar or unfamiliar people, evolutionarily unfit people, and people expressing a variety of emotions). Research testing these overgeneralization hypotheses has elucidated why we form first impressions from faces, what impressions we form, and what cues influence these impressions. This article focuses on commonalities in impressions across diverse perceivers, with additional brief attention given to individual differences in impressions and impression accuracy.
Biased Facial-Emotion Perception in Mental Health Disorders: A Possible Target for Psychological Intervention?
Authors: Penton-Voak Ian S. , Munafò Marcus R. , Looi Chung Yen
Published: June 2017

Our perception of emotion in the faces of others affects our own behavior and mood. Indeed, individuals with mood disorders such as depression and aggression often show biases in facial-emotion perception. Here, we review recent and ongoing research suggesting that biased emotion perception may be on the causal pathway of the onset and maintenance of mood disorders, and hence a potential target for intervention. Simple cognitive-bias modification tasks that change participants’ perception of facial expressions of emotion have shown some promise as a therapeutic technique. We outline further directions for continued research investigating the robustness and clinical impact of emotion-bias modification in real-world settings.
Culture Reveals a Flexible System for Face Processing
Authors: Caldara Roberto
Published: June 2017

The human face transmits a wealth of signals that readily provide crucial information for social interactions, such as facial identity and emotional expression. Nonetheless, a fundamental question remains debated: Is face processing governed by universal perceptual processes? It has long been presumed that this is the case. However, over the past decade, our work at the Eye and Brain Mapping Laboratory has called into question this widely held assumption. We have investigated the eye movements of Western and Eastern observers across various face-processing tasks to determine the effect of culture on perceptual processing. Commonalities aside, we found that Westerners distribute local fixations across the eye and mouth regions, whereas Easterners preferentially deploy central, global fixations during face recognition. Moreover, during the recognition of facial expressions of emotion, Westerners fixate the mouth relatively more to discriminate across expressions, whereas Easterners favor the eye region. Both observations demonstrate that the face system relies on different strategies to perform a range of socially relevant face-processing tasks with comparable levels of efficiency. Overall, these cultural perceptual biases challenge the view that the processes dedicated to face processing are universal, favoring instead the existence of distinct, flexible strategies. The way humans perceive the world and process faces is determined by experience and environmental factors.
Impacts of pulsed electric field and heat treatment on quality and sensory properties and microbial inactivation of pomegranate juice
Authors: Evrendilek Gulsun A
Published: June 2017

Synergistic effects of pulsed electric field+mild heat on quality properties of pomegranate juice were modeled using the best-fit multiple (non-) linear regression models with inactivation kinetics parameters of Escherichia coli O157:H7 and Staphylococcus aureus. No significant difference was detected between the control and the treated samples in terms of pH; °Brix; total antioxidant capacity; total monomeric anthocyanin content; total ascorbic acid concentration; and the sensory properties of flavor, taste, aftertaste, and overall acceptance ( p > 0.05). An exposure of 65.3 J and 40 ℃ caused an increase on conductivity; titratable acidity; L*, a*, and b* values; and a decrease of browning index, total phenolic content, total antioxidant capacity, total monomeric anthocyanin content, total ascorbic acid concentration, and in the sensory properties of color and sourness in pomegranate juice. The goodness-of-fit for the best-fit multiple (non-) linear regression models in descending order belonged to E. coli O157:H7 (92.98%), S. aureus (84.06%), color a* (83.9%), titratable acidity (81.3%), color L* (78.5%), color b* (78.3%), conductivity (74.8%), total phenolic content (74.1%), and total ascorbic acid concentration (64.74%), respectively. De and ze values for E. coli O157:H7 and S. aureus ranged from 105.64 to 1093.25 and from 79.18 to 1057.73 µs with 27.39 and 30.80 J, consequently.
Influence of Arctic seawater exposure on the flexural behavior of woven carbon/vinyl ester composites
Authors: Garcia R , Castellanos AG , Prabhakar P
Published: June 2017

In this paper, the adverse effects of sea water environment and arctic temperatures on woven carbon fiber/vinyl ester composites are explored in the form of moisture uptake, impact on flexural modulus, strength, and structural damage. The research presented here attempts to relate failure modes to the flexural behavior of these composites exposed to three key environmental conditions: sea water, arctic temperature and combined sea water/arctic condition. Sea water saturation in general degrades the flexural strength up to ≈19.45%. Microstructures of dry and saturated samples are compared using scanning electron microscopy, where a saturated surface with distinctive hue for wet samples is observed as compared to a rough (parched) surface in the dry samples, implying large concentrations of sea water in a thin layer at the specimen boundaries. Arctic exposure and combined condition on these laminates increase the flexural strength by about 23.1% and 36.2%, respectively. However, they tend to shift the post peak behavior from progressive to brittle-type failure as compared to dry samples, which is attributed to matrix and fiber embrittlement in the material system caused by exposure to low temperature. Further, relatively large variations are observed in the flexural strength values of samples exposed to the combined condition (sea water saturated + arctic), which can be attributed to the freezing of sea water that was entrapped during sea water saturation. Variation in the quantity and location of sea water entrapped can alter the flexural strength significantly. Due to the aforementioned flexural responses and failure behavior observed in woven carbon/vinyl ester composites exposed to sea water arctic environment, special consideration is required while designing critical load bearing components in naval applications to avoid possible catastrophic structural failure.
Surface Water Quality of Intensive Farming Areas Within the Santa Lucia River Basin of Uruguay
Authors: Barreto Patricia , Dogliotti Santiago , Perdomo Carlos
Published: June 2017

The Santa Lucia River basin provides drinking water to 60% of Uruguay population. The input of excessive amounts of nitrogen and phosphorus both from point and nonpoint sources could impair surface water quality and prevent its use for human consumption. The objective of this work was to evaluate surface water quality in small catchments under agricultural use located within this river basin. To this end, 5 streams and 4 small polders were surveyed between September 2008 and December 2009. The median concentrations of total phosphorus and total nitrogen in the streams across all sites and periods were 770 and 1659 µg L−1, respectively, exceeding in the case of total phosphorus national and international thresholds. Furthermore, soluble phosphorous, the most readily available form to algae, represented 88.3% of total phosphorus. Concentrations of phosphorous and nitrogen in polders were also high. The eutrophication process of this water bodies could be linked to the intensive agricultural land use in the area because the nutrient input from cities and industries was not relevant in these catchments.
Beyond social relationships: Investigating positive and negative attitudes towards violent protest within the same social movement
Authors: Vergani Matteo , Barton Greg , Iqbal Muhammad
Published: June 2017

Social relationships play a vitally important role in enabling political mobilization because they link people into networks of trusted others and they provide a sense of belonging, affirmation and sense of purpose. It is much less clear, however, why some individuals who are socially connected with individuals with positive attitudes towards violence, and who experience the same structural conditions, do not themselves have the same attitudes. This article investigates this research question by presenting original data from two networks of individuals with positive and negative attitudes towards violence in Italy, exploring the factors that might explain why some individuals reject violent protest despite having crucial bonds (i.e. friendship, kinship or romantic relationship) with individuals who have positive attitudes towards violence and despite belonging to the same social movement. The findings suggest that individuals with positive attitudes towards violence tend to have narrower and less sophisticated political views, are less professionally engaged, and are more driven by the search for meaning in life than individuals who reject violence.
Analysis of mixture structure and of its influence on combustion in a CAI engine
Authors: Knop Vincent
Published: June 2017

Homogeneous charge compression ignition combustion mode theoretically relies on a perfectly homogeneous air/fuel mixture simultaneously releasing heat across the whole combustion chamber. However, practical implementation always leads to a staged combustion process that is still significantly quicker than conventional spark ignition or compression ignition combustion modes. The degree of combustion staging is central to the limitation of combustion-induced noise, to cycle efficiency, as well as to combustion stability and completion. The present study numerically explored on the whole operating map the mixture structure at ignition for a specific type of homogeneous charge compression ignition combustion, namely the controlled auto-ignition combustion mode attained through burnt gas trapping with negative valve overlap. The analysis of the complete controlled auto-ignition operating map outlined the similarity of mixture structure for any operating condition and the mixture/chemistry interactions depending on the end-of-compression temperature domain. Temperature stratification appeared as the key input defining combustion-induced noise and combustion stability but mean in-cylinder temperature and dilution combine with temperature stratification to define operating map limitations.
Supporting children to resolve disputes
Authors: Church Amelia , Mashford-Scott Angie , Cohrssen Caroline
Published: June 2017

Teacher intervention in children’s disputes most commonly features cessation strategies, despite evidence showing the value of modelling problem-solving behaviours. Existing research has categorized strategies used by teachers in early childhood settings, but in this article we aim to illustrate how these practices are realized. Using the method of conversation analysis, we are able to show how children respond to different interventions, and in particular, how successful modelling of problem solving can be achieved with 4-year-old children. The extracts in this article make a case for the close study of teacher–child interactions and demonstrate how educators can support children to resolve their own disputes.
The impact of transferred vascularized toe joint length on motion arc of reconstructed finger proximal interphalangeal joints: a cadaveric study
Authors: Hsu Chung-Chen , Loh Charles Yuen Yung , Kao Dennis , Moran Steven L. , Lin Yu-Te
Published: June 2017

Vascularized toe joint transfer for finger proximal interphalangeal joint reconstruction can result in sub-optimal arc of motion and extension lag due to inappropriate intercalated bony segment length. We investigated the impact of intercalated segment length on passive arc of motion and extension lag of the reconstructed proximal interphalangeal joint. Cadaveric intercalated joint grafts were harvested from lesser toes and transferred to cadaveric fingers. The pre-determined finger proximal interphalangeal joint defect size was 2 cm. Three different intercalated segment lengths were inserted and resulting proximal interphalangeal joint arc of motion and extension lag were measured. The average arc of motion of finger proximal interphalangeal joints was 81° and 54° for toe proximal interphalangeal joints. Long intercalated segments had an average arc of motion of 30° with 32° extension lag. Equal-length intercalated segments had an average 49° arc of motion with 15° extension lag. Short intercalated segments had an average arc of motion of 71° with 8° extension lag. Shorter intercalated segments provide the greatest reduction in extension lag.
Why anarchy still matters for International Relations: On theories and things
Authors: Lechner Silviya
Published: June 2017

The category of anarchy is conventionally associated with the emergence of an autonomous discipline of International Relations (IR). Recently, Donnelly has argued that anarchy has never been central to IR (hierarchy is more weighty). His criticism targets not just concepts of anarchy but theories of anarchy and thereby expresses an anti-theory ethos tacitly accepted in the discipline. As a form of conceptual atomism, this ethos is hostile to structuralist and normative theories. This article aims to reinstate theoretical holism against conceptual atomism and to defend the enduring relevance of theories of international anarchy for IR. This is done by revisiting two classic, structuralist accounts of international anarchy articulated in Kenneth Waltz’s Theory of International Politics (scientific structuralism) and Hedley Bull’s Anarchical Society (normative structuralism). It will be shown that both represent coherent theoretical ‘wholes’ which reveal a more complex relationship between anarchy and hierarchy than supposed by critics and which recognise the important connection between the structure of international anarchy (whose key players are states) and the value of freedom. The conclusion examines the prospects of normative theories of international anarchy and ‘anarchical’ freedom in a globalising world where state agency is being challenged.
Triceps Ruptures After Fluoroquinolone Antibiotics: A Report of 2 Cases
Authors: Shybut Theodore B. , Puckett Ernest R.
Published: June 2017

Rupture of the triceps brachii tendon is exceedingly rare, and surgical repair is generally indicated. Fluoroquinolone antibiotics have been implicated in tendon pathology, including tendon ruptures. Triceps rupture has not been previously reported in the setting of fluoroquinolone antibiotic therapy. We present 2 cases of triceps tendon rupture after treatment with fluoroquinolones. In both cases, triceps repair was performed with good outcomes. These cases highlight a risk of fluoroquinolone-induced tendinopathy to athletes. The sports medicine team should be aware of this risk and consider it when choosing antibiotics to treat athletes.
Trainees’ perception of education in communication and professionalism across two programs in two countries
Authors: Lee Jan Hau , Quek Bin Huey , Hornik Christoph P , Shahdadpuri Raveen , Turner David A
Published: June 2017

Background:

Different health care systems impact on medical education.

Objective:

We aim to describe the differences and similarities in the perceptions of pediatric residents on education in professionalism and communication skills across two countries.

Methods:

We conducted a cross-sectional survey of pediatric residents in the United States and Singapore. A 108-item written questionnaire on perceptions regarding education in communication/professionalism was administered. A five-point Likert scale was used for each attribute in the survey. Quantitative analysis was performed using chi-square test.

Results:

Response rate was 65.9% (89/135). In the domain of professionalism, residents from both countries ranked shared decision making as the most important attribute (Singapore vs. USA: 26/50 (52.0%) vs. 19/39 (48.7%), p = 0.76). In contrast, there was a difference in ranking of the most important attribute in communication between the two countries, with dealing with difficult family and patient being most important for Singapore trainees (30/50(60.0%) vs. 8/39 (20.5%), p < 0.001). Direct observation and feedback and role modeling by seniors were the most common teaching methods in both centers. Main barriers in learning were high workload (55/89 (61.8%)) and time constraints (53/89 (59.6%)) in both countries. Promoters of teaching these competencies were similar, with role modeling by senior staff rated as most important.

Conclusions:

This investigation demonstrates more differences in the perception of how communication is taught compared to professionalism across two countries. Barriers and promoters to teaching were similar across these two countries, with role modeling being an important approach to teaching communication and professionalism across both countries.
Intertemporal Differences Among MTurk Workers: Time-Based Sample Variations and Implications for Online Data Collection
Authors: Casey Logan S. , Chandler Jesse , Levine Adam Seth , Proctor Andrew , Strolovitch Dara Z.
Published: June 2017

The online labor market Amazon Mechanical Turk (MTurk) is an increasingly popular source of respondents for social science research. A growing body of research has examined the demographic composition of MTurk workers as compared with that of other populations. While these comparisons have revealed the ways in which MTurk workers are and are not representative of the general population, variations among samples drawn from MTurk have received less attention. This article focuses on whether MTurk sample composition varies as a function of time. Specifically, we examine whether demographic characteristics vary by (a) time of day, (b) day of week, and serial position (i.e., earlier or later in data collection), both (c) across the entire data collection and (d) within specific batches. We find that day of week differences are minimal, but that time of day and serial position are associated with small but important variations in demographic composition. This demonstrates that MTurk samples cannot be presumed identical across different studies, potentially affecting reliability, validity, and efforts to reproduce findings.
Basic Color Terms in the Kazakh Language
Authors: Abdramanova Saule
Published: June 2017

The article addresses the issue of basic color terms and reviews the existing publications on color terms, including in the Kazakh language. The literature in Kazakhstani linguistics on basic color terms in Kazakh has mostly an empirical character, and it relies on the authors’ personal perceptions and examples from language—fiction, dictionaries, proverbs, and idioms. Most scholars identified the following inventory of basic color terms in Kazakh: ақ “white,” қара “black,” қызыл “red,” көк “blue,” сары “yellow,” and ала “multicolored.” The aim of the present article is to elaborate a list of basic color terms in the Kazakh language through conducting an experiment among Kazakh native speakers. The experiment was held among Kazakh young people to find out which color terms they name and how they order them. The results of the experiment showed that there is some difference in the way Kazakh scholars define and contemporary young Kazakhs name basic color terms. The young native speakers of Kazakh named eleven colors, such as Ақ (white), Қара (black), Сары (yellow), Жасыл (green), Қызыл (red), Көк (blue), Қоңыр (brown), Сүр (gray), Көгілдір (pale blue), Қызғылт (pink), and Күлгін (purple).
Are Psychosocial Resources Associated With Perceived Facial Aging in Men?
Authors: Noser Emilou , Walther Andreas , Ehlert Ulrike
Published: June 2017

Background: Looking younger than actual age has been related to a variety of health outcomes. Optimism, self-esteem, and relationship satisfaction are important psychosocial resources for mental health. Little is known about their relation with a younger facial appearance. Objective: This study analyzed whether these psychosocial resources are associated with a younger facial appearance and if their effects were mediated through mental health. Method: A sample of N = 223 self-reporting healthy men aged 40 to 75 years filled in questionnaires to assess optimism (Life Orientation Test–Revised), self-esteem (Multidimensional Self-Esteem Scale), relationship satisfaction (Relationship Assessment Scale), and mental health (Short-Form Health Survey). Five female raters estimated the visual age of each participant from a frontal face photograph. Results: Looking younger (compared with chronological age) was correlated with optimism, relationship satisfaction, and mental health. Mediation analyses and structural equation modeling indicated that mental health mediated the association between each psychosocial resource and a younger appearance. Discussion: The results emphasize the importance of promoting psychosocial resources and mental health in men 40+ for the maintenance of good health and the deceleration of facial aging.
How I treat patients with aggressive lymphoma at high risk of CNS relapse
Authors: Chin Collin K. , Cheah Chan Yoon
Published: June 2017

Central nervous system (CNS) relapses are an uncommon yet devastating complication of non-Hodgkin lymphomas. The identification of patients at high risk of secondary CNS relapse is therefore paramount. Retrospective data indicate prophylactic CNS-directed therapies may reduce the risk of CNS involvement; however, no consensus exists about dose, timing, or route of therapy. In addition, prophylaxis is not without risk of treatment-related complications and morbidity. Here, we present a series of case vignettes highlighting our approach to common dilemmas encountered in routine clinical practice. We review the method of assessing CNS relapse risk, factors that increase the likelihood of relapse including histologic subtype, MYC rearrangement, protein expression, and extranodal involvement, and review our clinical practice based on available evidence in administering CNS-directed prophylaxis.
Combining multidirectional source vector with antitruncation-artifact Fourier transform to calculate angle gathers from reverse time migration in two steps
Authors: Tang Chen , McMechan George A.
Published: June 2017

Because receiver wavefields reconstructed from observed data are not as stable as synthetic source wavefields, the source-propagation vector and the reflector normal have often been used to calculate angle-domain common-image gathers (ADCIGs) from reverse time migration. However, the existing data flows have three main limitations: (1) Calculating the propagation direction only at the wavefields with maximum amplitudes ignores multiarrivals; using the crosscorrelation imaging condition at each time step can include the multiarrivals but will result in backscattering artifacts. (2) Neither amplitude picking nor Poynting-vector calculations are accurate for overlapping wavefields. (3) Calculating the reflector normal in space is not accurate for a structurally complicated reflection image, and calculating it in the wavenumber ([Formula: see text]) domain may give Fourier truncation artifacts. We address these three limitations in an improved data flow with two steps: During imaging, we use a multidirectional Poynting vector (MPV) to calculate the propagation vectors of the source wavefield at each time step and output intermediate source-angle-domain CIGs (SACIGs). After imaging, we use an antitruncation-artifact Fourier transform (ATFT) to convert SACIGs to ADCIGs in the [Formula: see text]-domain. To achieve the new flow, another three innovative aspects are included. In the first step, we develop an angle-tapering scheme to remove the Fourier truncation artifacts during the wave decomposition (of MPV) while preserving the amplitudes, and we use a wavefield decomposition plus angle-filter imaging condition to remove the backscattering artifacts in the SACIGs. In the second step, we compare two algorithms to remove the Fourier truncation artifacts that are caused by the plane-wave assumption. One uses an antileakage FT (ALFT) in local windows; the other uses an antitruncation-artifact FT, which relaxes the plane-wave assumption and thus can be done for the global space. The second algorithm is preferred. Numerical tests indicate that this new flow (source-side MPV plus ATFT) gives high-quality ADCIGs.
S-transform and Fourier transform frequency spectra of broadband seismic signals
Authors: Wu Lin , Castagna John
Published: June 2017

The S-transform is one way to transform a 1D seismogram into a 2D time-frequency analysis. We have investigated its use to compute seismic interpretive attributes, such as peak frequency and bandwidth. The S-transform normalizes a frequency-dependent Gaussian window by a factor proportional to the absolute value of frequency. This normalization biases spectral amplitudes toward higher frequency. At a given time, the S-transform spectrum has similar characteristics to the Fourier spectrum of the derivative of the waveform. For narrowband signals, this has little impact on the peak frequency of the time-frequency analysis. However, for broadband seismic signals, such as a Ricker wavelet, the S-transform peak frequency is significantly higher than the Fourier peak frequency and can thus be misleading. Numerical comparisons of spectra from a variety of waveforms support the general rule that S-transform peak frequencies are equal to or greater than Fourier-transform peak frequencies. Comparisons on real seismic data suggest that this effect should be considered when interpreting S-transform spectral decompositions. One solution is to define the unscaled S-transform by removing the normalization factor. Tests comparing the unscaled S-transform with the S-transform and the short-windowed Fourier transform indicate that removing the scale factor improves the time-frequency analysis on reflection seismic data. This improvement is most relevant for quantitative applications.
A generalized view on normal moveout
Authors: Schwarz Benjamin , Gajewski Dirk
Published: June 2017

Although in the past, in the context of stacking, traveltime moveout was only formulated in individual common-midpoint (CMP) gathers, multiparameter stacking uses normal moveout (NMO) approximations that span several neighboring CMPs. Multiparameter expressions such as the common reflection surface (CRS) or multifocusing are parameterized in terms of local slopes and curvatures of emerging wavefronts rather than effective velocities, which makes these approaches appear conceptually different from conventional velocity analysis. As a consequence, the unifying nature of multiparameter NMO is still not well-appreciated. In addition, CRS and multifocusing show distinctly different behavior in that they respond differently to the overburden heterogeneity and curvature of the target interface, and they either are or are not susceptible to moveout stretch. In our work, we seek to demystify the wavefront picture by demonstrating that the conventional and multidimensional NMO operators can conveniently be derived from the same auxiliary straight-ray geometry, either representing the optical projection or formulated in an effective replacement medium. Following the early work of de Bazelaire, we suggest a simple transformation between both domains and introduce generalized dual representations of the hyperbolic CRS, multifocusing, and the two recently introduced double-square-root expressions implicit CRS and nonhyperbolic CRS. In addition, we evaluate a generalized finite-offset NMO expression that can likewise be applied to active-source diffraction data and passive seismic events. Synthetic examples suggest unification, conveniently explain the origin of moveout stretch, and indicate that the joint use of different NMO approximations offers new insight into the character and origin of different wavefield components.
Kind of Miles: The Many Moods of Stuart Hall
Authors: Farred Grant
Published: June 2017

“When I was nineteen, Miles Davis put his finger on my soul, and it never went away,” Stuart Hall reflects in John Akomfrah’s documentary, The Stuart Hall Project. Miles Davis not only “touched” Hall’s soul, but the music and its many moods, its vagaries, its experimentations provided a lodestar, a touchstone, and a balm for that self-same Jamaican soul. Miles Davis provided, at the very least, jazz as a musical genre, as a mode of being deeply inflected by race, as a means of delivering solace, succor, and sustenance for two black souls. While there is no symmetry, perfect or imperfect, between Miles Davis’s music and Stuart Hall’s work, what does emerge through The Stuart Hall Project is a glimpse into the soulfulness of Stuart Hall’s thinking. Stuart Hall’s work has shown itself to be ceaselessly inventive, always in search of the conceptual answers to the political demands of the day, deft and subtle in its ability to address the difficulties of dislocation, deracination, and out-of-placeness that is the everyday lived reality of the diaspora. Akomfrah draws us into Hall’s life through Davis’s discography. We are invited to access Hall, not only through his work, his writings, public appearances, and colleagues and comrades, which sometimes are indistinguishable from the other, but through the portal of a radical jazz figure. As such, Stuart Hall makes himself unfamiliar, if only for the shortest moment, and in so doing he compels us to think of him on other terms, on deeply intimate, heartfelt, soulful terms—propensities that are so clearly etched in Miles Davis’s music. In this way, it is possible to say that the Hall oeuvre is a felicitous testament to the challenges presented by Miles Davis’s discography, one that allows us to glimpse a heretofore unseen creative intimacy between two of the most gifted and soulful thinkers of the black condition.
Ars and Techne: Jack Whitten Retrospective
Authors: Carey Chanda Laine
Published: June 2017

This essay closely surveys Jack Whitten’s 2014 retrospective at the Museum of Contemporary Art San Diego. An emphasis on the aesthetics of gestural abstraction informs Whitten’s work of the last five decades, resulting in a body of work that pushes through historical events and innovative techniques of painting that demonstrate the depths of his commitment to gestural abstraction as his primary mode of creative expression. Attentive to shifting terrain in technology, culture, and African American history during his lifetime, Whitten’s work participates in a memorial project that defines his oeuvre as one that establishes his life experience as social history through the art of painting. His lifelong practice of abstraction, and the resulting bodies of work exhibited in the retrospective, confirm a prominent place for Whitten’s among the outstanding practitioners of American painting.
Acid–base physiology, neurobiology and behaviour in relation to CO2-induced ocean acidification
Authors: Tresguerres Martin , Hamilton Trevor J.
Published: June 2017

Experimental exposure to ocean and freshwater acidification affects the behaviour of multiple aquatic organisms in laboratory tests. One proposed cause involves an imbalance in plasma chloride and bicarbonate ion concentrations as a result of acid–base regulation, causing the reversal of ionic fluxes through GABAA receptors, which leads to altered neuronal function. This model is exclusively based on differential effects of the GABAA receptor antagonist gabazine on control animals and those exposed to elevated CO2. However, direct measurements of actual chloride and bicarbonate concentrations in neurons and their extracellular fluids and of GABAA receptor properties in aquatic organisms are largely lacking. Similarly, very little is known about potential compensatory mechanisms, and about alternative mechanisms that might lead to ocean acidification-induced behavioural changes. This article reviews the current knowledge on acid–base physiology, neurobiology, pharmacology and behaviour in relation to marine CO2-induced acidification, and identifies important topics for future research that will help us to understand the potential effects of predicted levels of aquatic acidification on organisms.
Optimal Three-Part Tariff Plans
Authors: Fibich Gadi , Klein Roy , Koenigsberg Oded , Muller Eitan
Published: June 2017

Service providers, such as cell phone carriers, often offer three-part tariff plans that consist of three levers: A fixed fee, an allowance of free units, and a price per unit above the allowance. In previous studies the optimal three-part tariff contract was characterized using the standard first-order conditions approach. Because this optimization problem is nonsmooth, however, it could only be solved in a few simple cases. In this study we employ a different methodology that is based on obtaining a global bound for the firm profit, and then showing that this bound is attained by the optimal plan. This approach allows us to explicitly calculate the optimal three-part tariff plan under quite general conditions, where consumers are rational, they have a general utility function, they experience psychological costs when they exceed the number of free units, they have deterministic or stochastic consumption rates, they are homogeneous or heterogeneous, and the firm costs are fixed or depend on the usage level.

Intravenous therapy and infection control
Authors: Higginson Ray
Published: June 2017

Universal precautions and general infection control measures needs to be considered when undertaking any clinical procedure. When administering intravenous (IV) therapy (medicines and/or maintenance fluids), specific measures need to be considered. This is especially important in elderly patients or if administering IV therapy to those with compromised immunity. There are many reasons why patients may need to receive IV therapy and these will all present with potential problems. This article will discuss IV therapy and some of the infection control procedures one must undertake when administering it.
Improving healthcare by promoting time efficiency through standardisation of hospital wards
Authors: Nixon Martha , Pinto Keith Gomes , Kostalas Marcos , Taylor John , Williams David
Published: June 2017

Aim:

This study aimed to measure how different ward layouts can impact on working efficiency. This can have significant impact on productivity, patient care and patient safety.

Method:

The time taken for 20 junior doctors to collect the equipment to perform two routine tasks was measured. This was repeated on five hospital wards.

Results:

The time taken to perform the tasks on different wards varied significantly. It could take up to 60 seconds longer to perform a very simple task depending on the ward. The junior doctors performed consistently better on two wards indicating that the ward layout was responsible.

Conclusion:

Ward layout can have significant impact on efficiency. In the current NHS, where multiple staff members regularly move between wards, implementing very simple measures and standardising ward layout could have dramatic impact on efficiency. This could improve patient care and patient safety.
Weight management: Addressing barriers and improving practice
Authors: Croghan Emma
Published: June 2017

The National Child Measurement Programme (NCMP) has been tracking the rise in obesity in England since 2005. School nurses, as public health professionals, have a key role to play in identifying and supporting children and young people with weight issues, and their families. However, while the NCMP is very useful in providing data, there are number of challenges to intervention which need to be overcome. This article looks at some of these barriers and ways to overcome them.
