Effect of zone size on the convergence of exact solutions for diffusion in single phase systems with planar, cylindrical or spherical geometry

NASA Technical Reports Server (NTRS)

Unnam, J.; Tenney, D. R.

1981-01-01

Exact solutions for diffusion in single phase binary alloy systems with constant diffusion coefficient and zero-flux boundary condition have been evaluated to establish the optimum zone size of applicability. Planar, cylindrical and spherical interface geometry, and finite, singly infinite, and doubly infinite systems are treated. Two solutions are presented for each geometry, one well suited to short diffusion times, and one to long times. The effect of zone-size on the convergence of these solutions is discussed. A generalized form of the diffusion solution for doubly infinite systems is proposed.

Slab Geometry and Stress State of the Southwestern Colombia Subduction Zone

NASA Astrophysics Data System (ADS)

Chang, Ying

A high rate of intermediate-depth earthquakes is concentrates in the Cauca cluster (3.5°N-5.5°N) and isolated from nearby seismicity in the southwestern Colombia subduction zone. Previously-studied nests of intermediate-depth earthquakes show that a high seismicity rate is often associated with a slab tear, detachment, or contortion. The cause of the less-studied Cauca cluster is unknown. To investigate the cause, we image the slab geometry using precise relative locations of intermediate-depth earthquakes. We use the earthquake catalog produced and seismic waveforms recorded by the Colombian National Seismic Network from January 2010 to March 2014. We calculate the focal mechanisms to examine whether the earthquakes reactivate pre-existing faults or form new fractures. The focal mechanisms are inverted for the intraslab stress field to check the stress guide hypothesis and to evaluate the stress orientations with regard to the change in the slab geometry. The earthquake relocations indicate that the Cauca segment has a continuous 20 km thick seismic zone and increases in dip angle from north to south. Two 40-km-tall fingers of earthquakes extend out of the slab and into the mantle wedge. Different from the previously-studied nests, the Cauca cluster does not correspond to slab contortions or tearing. The cluster may be associated with a high amount of dehydrated fluid. The determined focal mechanisms of 69 earthquakes have various types and variably-oriented nodal planes, corresponding to the reactivation of pre-existing faults and the formation of new fractures. The results of stress inversion show that the extensional axis in the northern Cauca segment is in the plane of the slab and 25° from the downdip direction, and the southern part has along-strike extension. The compression is subnormal to the plane of the slab. The stress field supports the stress guide hypothesis and shows a consistent rotation with increase in slab dip angle.

Characterizing Englacial Attenuation and Grounding Zone Geometry Using Airborne Radar Sounding

NASA Astrophysics Data System (ADS)

Schroeder, D. M.; Grima, C.; Blankenship, D. D.

2014-12-01

The impact of warm ocean water on ice sheet retreat and stability is a one of the primary drivers and sources of uncertainty for the rate of global sea level rise. One critical but challenging observation required to understand and model this impact is the location and extent of grounding ice sheet zones. However, existing surface topography based techniques do not directly detect the location where ocean water reaches (or breaches) grounded ice at the bed, which can significantly affect ice sheet stability. The primary geophysical tool for directly observing the basal properties of ice sheets is airborne radar sounding. However, uncertainty in englacial attenuation from unknown ice temperature and chemistry can lead to erroneous interpretation of subglacial conditions from bed echo strengths alone . Recently developed analysis techniques for radar sounding data have overcome this challenge by taking advantage of information in the angular distribution of bed echo energy and joint modeling of radar returns and water routing. We have developed similar approaches to analyze the spatial pattern and character of echoes to address the problems of improved characterization of grounding zone geometry and englacial attenuation. The spatial signal of the transition from an ice-bed interface to an ice-ocean interface is an increase in bed echo strength. However, rapidly changing attenuation near the grounding zone prevents the unambiguous interpretation of this signal in typical echo strength profiles and violates the assumptions of existing empirical attenuation correction techniques. We present a technique that treat bed echoes as continuous signals to take advantage of along-profile ice thickness and echo strength variations to constrain the spatial pattern of attenuation and detect the grounding zone transition. The transition from an ice-bed interface to an ice-ocean interface will also result in a change in the processes that determine basal interface morphology (e

Initiation of deformation of the Eastern California Shear Zone: Constraints from Garlock fault geometry and GPS observations

USGS Publications Warehouse

Gan, Weijun; Zhang, P.; Shen, Z.-K.; Prescott, W.H.; Svarc, J.L.

2003-01-01

We suggest a 2-stage deformation model for the Eastern California Shear Zone (ECSZ) to explain the geometry of the Garlock fault trace. We assume the Garlock fault was originally straight and then was gradually curved by right-lateral shear deformation across the ECSZ. In our 2-stage deformation model, the first stage involves uniform shear deformation across the eastern part of the shear zone, and the second stage involves uniform shear deformation across the entire shear zone. In addition to the current shape of the Garlock fault, our model incorporates constraints on contemporary deformation rates provided by GPS observations. We find that the best fitting age for initiation of shear in eastern part of the ECSZ is about 5.0 ?? 0.4 Ma, and that deformation of the western part started about 1.6 Myr later.

Influence of increasing convergence obliquity and shallow slab geometry onto tectonic deformation and seismogenic behavior along the Northern Lesser Antilles zone

NASA Astrophysics Data System (ADS)

Laurencin, M.; Graindorge, D.; Klingelhoefer, F.; Marcaillou, B.; Evain, M.

2018-06-01

In subduction zones, the 3D geometry of the plate interface is one of the key parameters that controls margin tectonic deformation, interplate coupling and seismogenic behavior. The North American plate subducts beneath the convex Northern Lesser Antilles margin. This convergent plate boundary, with a northward increasing convergence obliquity, turns into a sinistral strike-slip limit at the northwestern end of the system. This geodynamic context suggests a complex slab geometry, which has never been imaged before. Moreover, the seismic activity and particularly the number of events with thrust focal mechanism compatible with subduction earthquakes, increases northward from the Barbuda-Anguilla segment to the Anguilla-Virgin Islands segment. One of the major questions in this area is thus to analyze the influence of the increasing convergence obliquity and the slab geometry onto tectonic deformation and seismogenic behavior of the subduction zone. Based on wide-angle and multichannel reflection seismic data acquired during the Antithesis cruises (2013-2016), we decipher the deep structure of this subduction zone. Velocity models derived from wide-angle data acquired across the Anegada Passage are consistent with the presence of a crust of oceanic affinity thickened by hotspot magmatism and probably affected by the Upper Cretaceous-Eocene arc magmatism forming the 'Great Arc of the Caribbean'. The slab is shallower beneath the Anguilla-Virgin Islands margin segment than beneath the Anguilla-Barbuda segment which is likely to be directly related to the convex geometry of the upper plate. This shallower slab is located under the forearc where earthquakes and partitioning deformations increase locally. Thus, the shallowing slab might result in local greater interplate coupling and basal friction favoring seismic activity and tectonic partitioning beneath the Virgin Islands platform.

The geometry of pull-apart basins in the southern part of Sumatran strike-slip fault zone

NASA Astrophysics Data System (ADS)

Aribowo, Sonny

2018-02-01

Models of pull-apart basin geometry have been described by many previous studies in a variety tectonic setting. 2D geometry of Ranau Lake represents a pull-apart basin in the Sumatran Fault Zone. However, there are unclear geomorphic traces of two sub-parallel overlapping strike-slip faults in the boundary of the lake. Nonetheless, clear geomorphic traces that parallel to Kumering Segment of the Sumatran Fault are considered as inactive faults in the southern side of the lake. I demonstrate the angular characteristics of the Ranau Lake and Suoh complex pull-apart basins and compare with pull-apart basin examples from published studies. I use digital elevation model (DEM) image to sketch the shape of the depression of Ranau Lake and Suoh Valley and measure 2D geometry of pull-apart basins. This study shows that Ranau Lake is not a pull-apart basin, and the pull-apart basin is actually located in the eastern side of the lake. Since there is a clear connection between pull-apart basin and volcanic activity in Sumatra, I also predict that the unclear trace of the pull-apart basin near Ranau Lake may be covered by Ranau Caldera and Seminung volcanic products.

A high-order multi-zone cut-stencil method for numerical simulations of high-speed flows over complex geometries

NASA Astrophysics Data System (ADS)

Greene, Patrick T.; Eldredge, Jeff D.; Zhong, Xiaolin; Kim, John

2016-07-01

In this paper, we present a method for performing uniformly high-order direct numerical simulations of high-speed flows over arbitrary geometries. The method was developed with the goal of simulating and studying the effects of complex isolated roughness elements on the stability of hypersonic boundary layers. The simulations are carried out on Cartesian grids with the geometries imposed by a third-order cut-stencil method. A fifth-order hybrid weighted essentially non-oscillatory scheme was implemented to capture any steep gradients in the flow created by the geometries and a third-order Runge-Kutta method is used for time advancement. A multi-zone refinement method was also utilized to provide extra resolution at locations with expected complex physics. The combination results in a globally fourth-order scheme in space and third order in time. Results confirming the method's high order of convergence are shown. Two-dimensional and three-dimensional test cases are presented and show good agreement with previous results. A simulation of Mach 3 flow over the logo of the Ubuntu Linux distribution is shown to demonstrate the method's capabilities for handling complex geometries. Results for Mach 6 wall-bounded flow over a three-dimensional cylindrical roughness element are also presented. The results demonstrate that the method is a promising tool for the study of hypersonic roughness-induced transition.

Density structure and geometry of the Costa Rican subduction zone from 3-D gravity modeling and local earthquake data

NASA Astrophysics Data System (ADS)

Lücke, O. H.; Arroyo, I. G.

2015-07-01

The eastern part of the oceanic Cocos Plate presents a heterogeneous crustal structure due to diverse origins and ages as well as plate-hot spot interactions which originated the Cocos Ridge, a structure that converges with the Caribbean Plate in southeastern Costa Rica. The complex structure of the oceanic plate directly influences the dynamics and geometry of the subduction zone along the Middle American Trench. In this paper an integrated interpretation of the slab geometry is presented based on three-dimensional density modeling of combined satellite and surface gravity data, constrained by available geophysical and geological data and seismological information obtained from local networks. The results show the continuation of steep subduction geometry from the Nicaraguan margin into Northwestern Costa Rica, followed by a moderate dipping slab under the Central Cordillera toward the end of the Central American Volcanic Arc. To the southeast end of the volcanic arc, our preferred model shows a steep, coherent slab that extends up to the landward projection of the Panama Fracture Zone. Overall, a gradual change in the depth of the intraplate seismicity is observed, reaching 220 km in the northwestern part, and becoming progressively shallower toward the southeast, where it reaches a terminal depth of 75 km. The changes in the terminal depth of the observed seismicity correlate with the increased density in the modeled slab. The absence of intermediate depth intraplate seismicity in the southeastern section and the higher densities for the subducted slab in this area, support a model in which dehydration reactions in the subducted slab cease at a shallower depth, originating an anhydrous and thus aseismic slab.

The northern Lesser Antilles oblique subduction zone: new insight about the upper plate deformation, 3D slab geometry and interplate coupling.

NASA Astrophysics Data System (ADS)

Marcaillou, B.; Laurencin, M.; Graindorge, D.; Klingelhoefer, F.

2017-12-01

In subduction zones, the 3D geometry of the plate interface is thought to be a key parameter for the control of margin tectonic deformation, interplate coupling and seismogenic behavior. In the northern Caribbean subduction, precisely between the Virgin Islands and northern Lesser Antilles, these subjects remain controversial or unresolved. During the ANTITHESIS cruises (2013-2016), we recorded wide-angle seismic, multichannel reflection seismic and bathymetric data along this zone in order to constrain the nature and the geometry of the subducting and upper plate. This experiment results in the following conclusions: 1) The Anegada Passage is a 450-km long structure accross the forearc related to the extension due to the collision with the Bahamas platform. 2) More recently, the tectonic partitioning due to the plate convergence obliquity re-activated the Anegada Passage in the left-lateral strike-slip system. The partitioning also generated the left-lateral strike-slip Bunce Fault, separating the accretionary prism from the forearc. 3) Offshore of the Virgin Islands margin, the subducting plate shows normal faults parallel to the ancient spreading center that correspond to the primary fabric of the oceanic crust. In contrast, offshore of Barbuda Island, the oceanic crust fabric is unresolved (fracture zone?, exhumed mantle? ). 4) In the direction of the plate convergence vector, the slab deepening angle decreases northward. It results in a shallower slab beneath the Virgin Islands Platform compared to the St Martin-Barbuda forearc. In the past, the collision of the Bahamas platform likely changed the geodynamic settings of the northeastern corner of the Caribbean subduction zone and we present a revised geodynamic history of the region. Currently, various features are likely to control the 3D geometry of the slab: the margin convexity, the convergence obliquity, the heterogeneity of the primary fabric of the oceanic crust and the Bahamas docking. We suggest that

The transparency criteria of the German statutory health insurance on joint contracture prevention have led to controversies about the appropriate assessment, prevention and treatment as well as to various actions in nursing practice. However, appropriate nursing assessments and proven treatment options are lacking so far. It is unclear whether textbooks on nursing reflect these uncertainties. Search for textbooks on nursing through internet-based search engines and publisher registers, data extraction by one investigator and control by a second. A total of 35 textbooks with contributions on joint contractures were identified of which 25 included a definition, causes/risk factors are presented in 32 textbooks and assessments are presented in 5 books. Most often positioning into a physiological or functional neutral position and passive moving of limbs are recommended as passive prophylaxis. Recommended therapeutic and preventive options do not differ. None of the textbooks reflect that there is a lack of scientific knowledge on the subject. Textbooks on nursing do not deal with complete and scientific sound information on joint contractures.

How Current Are Leading Evidence-Based Medical Textbooks? An Analytic Survey of Four Online Textbooks

PubMed Central

2012-01-01

Background The consistency of treatment recommendations of evidence-based medical textbooks with more recently published evidence has not been investigated to date. Inconsistencies could affect the quality of medical care. Objective To determine the frequency with which topics in leading online evidence-based medical textbooks report treatment recommendations consistent with more recently published research evidence. Methods Summarized treatment recommendations in 200 clinical topics (ie, disease states) covered in four evidence-based textbooks–UpToDate, Physicians’ Information Education Resource (PIER), DynaMed, and Best Practice–were compared with articles identified in an evidence rating service (McMaster Premium Literature Service, PLUS) since the date of the most recent topic updates in each textbook. Textbook treatment recommendations were compared with article results to determine if the articles provided different, new conclusions. From these findings, the proportion of topics which potentially require updating in each textbook was calculated. Results 478 clinical topics were assessed for inclusion to find 200 topics that were addressed by all four textbooks. The proportion of topics for which there was 1 or more recently published articles found in PLUS with evidence that differed from the textbooks’ treatment recommendations was 23% (95% CI 17-29%) for DynaMed, 52% (95% CI 45-59%) for UpToDate, 55% (95% CI 48-61%) for PIER, and 60% (95% CI 53-66%) for Best Practice (χ 2 3=65.3, P<.001). The time since the last update for each textbook averaged from 170 days (range 131-209) for DynaMed, to 488 days (range 423-554) for PIER (P<.001 across all textbooks). Conclusions In online evidence-based textbooks, the proportion of topics with potentially outdated treatment recommendations varies substantially. PMID:23220465

Numerical analysis of residual stresses in preforms of stress applying part for PANDA-type polarization maintaining optical fibers in view of technological imperfections of the doped zone geometry

NASA Astrophysics Data System (ADS)

Trufanov, Aleksandr N.; Trufanov, Nikolay A.; Semenov, Nikita V.

2016-09-01

The experimental data analysis of the stress applying rod section geometry for the PANDA-type polarization maintaining optical fiber has been performed. The dependencies of the change in the radial dimensions of the preform and the doping boundary on the angular coordinate have been obtained. The original algorithm of experimental data statistic analysis, which enables determination of the specimens' characteristic form of section, has been described. The influence of actual doped zone geometry on the residual stress fields formed during the stress rod preform fabrication has been investigated. It has been established that the deviation of the boundary between pure silica and the doped zone from the circular shape results in dissymmetry and local concentrations of the residual stress fields along the section, which can cause preforms destruction at high degrees of doping. The observed geometry deviations of up to 10% lead to the increase of the maximum stress intensity value by over 20%.

Andrikopoulou, M; Michala, L; Creighton, S M; Liao, L-M

2013-10-01

When a healthy woman expresses concerns about her vulva, the doctor's response should be informed by clinical knowledge. For many doctors, accumulation of such knowledge would have begun with undergraduate teaching and medical textbooks. The aim of this study is to examine the information on female genital morphology in medical textbooks. A total of 59 gynaecology and anatomy textbooks were searched for information on the dimensions of vulval constitutent parts. No textbook gave measurements for all vulval structures. Vaginal length was reported in 21/59 textbooks, clitoral size in 15/59 and labia minora in 1/59. Where measurements appear, they suggest narrower ranges than recent reports. Information of vulval morphology is scanty and inaccurate in medical textbooks. The general lack of professional resources means that doctors may consciously or non-consciously rely upon personal experiences and popular culture to form their opinions, as do their patients.

Visualizing Three-dimensional Slab Geometries with ShowEarthModel

NASA Astrophysics Data System (ADS)

Chang, B.; Jadamec, M. A.; Fischer, K. M.; Kreylos, O.; Yikilmaz, M. B.

2017-12-01

Seismic data that characterize the morphology of modern subducted slabs on Earth suggest that a two-dimensional paradigm is no longer adequate to describe the subduction process. Here we demonstrate the effect of data exploration of three-dimensional (3D) global slab geometries with the open source program ShowEarthModel. ShowEarthModel was designed specifically to support data exploration, by focusing on interactivity and real-time response using the Vrui toolkit. Sixteen movies are presented that explore the 3D complexity of modern subduction zones on Earth. The first movie provides a guided tour through the Earth's major subduction zones, comparing the global slab geometry data sets of Gudmundsson and Sambridge (1998), Syracuse and Abers (2006), and Hayes et al. (2012). Fifteen regional movies explore the individual subduction zones and regions intersecting slabs, using the Hayes et al. (2012) slab geometry models where available and the Engdahl and Villasenor (2002) global earthquake data set. Viewing the subduction zones in this way provides an improved conceptualization of the 3D morphology within a given subduction zone as well as the 3D spatial relations between the intersecting slabs. This approach provides a powerful tool for rendering earth properties and broadening capabilities in both Earth Science research and education by allowing for whole earth visualization. The 3D characterization of global slab geometries is placed in the context of 3D slab-driven mantle flow and observations of shear wave splitting in subduction zones. These visualizations contribute to the paradigm shift from a 2D to 3D subduction framework by facilitating the conceptualization of the modern subduction system on Earth in 3D space.

Modeling earthquake sequences along the Manila subduction zone: Effects of three-dimensional fault geometry

NASA Astrophysics Data System (ADS)

Yu, Hongyu; Liu, Yajing; Yang, Hongfeng; Ning, Jieyuan

2018-05-01

To assess the potential of catastrophic megathrust earthquakes (MW > 8) along the Manila Trench, the eastern boundary of the South China Sea, we incorporate a 3D non-planar fault geometry in the framework of rate-state friction to simulate earthquake rupture sequences along the fault segment between 15°N-19°N of northern Luzon. Our simulation results demonstrate that the first-order fault geometry heterogeneity, the transitional-segment (possibly related to the subducting Scarborough seamount chain) connecting the steeper south segment and the flatter north segment, controls earthquake rupture behaviors. The strong along-strike curvature at the transitional-segment typically leads to partial ruptures of MW 8.3 and MW 7.8 along the southern and northern segments respectively. The entire fault occasionally ruptures in MW 8.8 events when the cumulative stress in the transitional-segment is sufficiently high to overcome the geometrical inhibition. Fault shear stress evolution, represented by the S-ratio, is clearly modulated by the width of seismogenic zone (W). At a constant plate convergence rate, a larger W indicates on average lower interseismic stress loading rate and longer rupture recurrence period, and could slow down or sometimes stop ruptures that initiated from a narrower portion. Moreover, the modeled interseismic slip rate before whole-fault rupture events is comparable with the coupling state that was inferred from the interplate seismicity distribution, suggesting the Manila trench could potentially rupture in a M8+ earthquake.

Queering high school biology textbooks

NASA Astrophysics Data System (ADS)

Snyder, Vicky L.; Broadway, Francis S.

2004-08-01

As teachers committed to educating all students, we need to learn more about how instructional materials shape representations of sexuality and gender. Through its insistent deconstruction of the norms that structure practice and belief, queer theory offers perspectives from which science educators can question assumptions embedded in textbooks. This article applies queer theory to analyze eight biology textbooks used in the United States. Specifically, we ask how biology textbooks address sexuality outside the heterosexual norm and if they propagate heteronormative attitudes. The textbooks examined offer deafening silences, antiseptic factoids, socially sanitized concepts, and politically correct binary-gendered illustrations. In these textbooks, the term homosexuality was used only in the context of AIDS where, along with iv drug users, they were identified as an affected group. The pervasive acceptance of heteronormative behavior privileges students that fit the heterosexual norm, and oppresses through omission and silence those who do not. We offer implications for practice to help science educators broaden their perspectives on the constructs of sexuality and gender to construct new ways of knowing and understanding differences in science classrooms and the natural world.

Juan de Fuca slab geometry and its relation to Wadati-Benioff zone seismicity

USGS Publications Warehouse

McCrory, Patricia A.; Blair, J. Luke; Waldhause, Felix; Oppenheimer, David H.

2012-01-01

A new model of the subducted Juan de Fuca plate beneath western North America allows first-order correlations between the occurrence of Wadati-Benioff zone earthquakes and slab geometry, temperature, and hydration state. The geo-referenced 3D model, constructed from weighted control points, integrates depth information from earthquake locations and regional seismic velocity studies. We use the model to separate earthquakes that occur in the Cascadia forearc from those that occur within the underlying Juan de Fuca plate and thereby reveal previously obscured details regarding the spatial distribution of earthquakes. Seismicity within the slab is most prevalent where the slab is warped beneath northwestern California and western Washington suggesting that slab flexure, in addition to expected metamorphic dehydration processes, promotes earthquake occurrence within the subducted oceanic plate. Earthquake patterns beneath western Vancouver Island are consistent with slab dehydration processes. Conversely, the lack of slab earthquakes beneath western Oregon is consistent with an anhydrous slab. Double-differenced relocated seismicity resolves a double seismic zone within the slab beneath northwestern California that strongly constrains the location of the plate interface and delineates a cluster of seismicity 10 km above the surface that includes the 1992 M7.1 Mendocino earthquake. We infer that this earthquake ruptured a surface within the Cascadia accretionary margin above the Juan de Fuca plate. We further speculate that this earthquake is associated with a detached fragment of former Farallon plate. Other subsurface tectonic elements within the forearc may have the potential to generate similar damaging earthquakes.

A readability analysis of elementary-level science textbooks

NASA Astrophysics Data System (ADS)

Trainer, Robyn

Given both the unprecedented attention to the importance of providing children with the best possible science textbooks and the overwhelming evidence that students in the United States are severely lacking the most basic science knowledge, the decline in the number of students pursuing science degrees is alarming. In spite of all the efforts being made, a disparity still exists between (1) the wealth of science information available, (2) the apparent ease of access to scientific information, and (3) the lack of scientific academic progress being made in classrooms across the United States. A literature review was conducted which included the areas of textbook analysis and textbook readability levels, the fields of textbook analysis and readability, and findings from recently published books about textbook readability. The majority of the literature reflected an urgent need for science textbooks to be revised. Based on the information gathered during the literature review, the study examined the readability levels of elementary level science textbooks that were published by six textbook publishers. Results from the study revealed that when used properly, readability formulas provide an objective look at textbooks. After applying these formulas to the selected elementary level science textbooks, it became clear that very few changes were implemented between the most recent previous editions and the current editions. The textbooks remain too difficult for the students using them. The findings from this study will help science textbook publishers and textbook writers see that some changes need to be made in the way their textbooks are written. In order to maintain a competitive edge in the global marketplace, more students need to pursue science. In order for more students to do that, they need to pursue science degrees, but in order for them to pursue science degrees, they need to have a certain degree of confidence and level of interest in the subject matter.

Comparative analysis of a nontraditional general chemistry textbook and selected traditional textbooks used in Texas community colleges

NASA Astrophysics Data System (ADS)

Salvato, Steven Walter

The purpose of this study was to analyze questions within the chapters of a nontraditional general chemistry textbook and the four general chemistry textbooks most widely used by Texas community colleges in order to determine if the questions require higher- or lower-order thinking according to Bloom's taxonomy. The study employed quantitative methods. Bloom's taxonomy (Bloom, Engelhart, Furst, Hill, & Krathwohl, 1956) was utilized as the main instrument in the study. Additional tools were used to help classify the questions into the proper category of the taxonomy (McBeath, 1992; Metfessel, Michael, & Kirsner, 1969). The top four general chemistry textbooks used in Texas community colleges and Chemistry: A Project of the American Chemical Society (Bell et al., 2005) were analyzed during the fall semester of 2010 in order to categorize the questions within the chapters into one of the six levels of Bloom's taxonomy. Two coders were used to assess reliability. The data were analyzed using descriptive and inferential methods. The descriptive method involved calculation of the frequencies and percentages of coded questions from the books as belonging to the six categories of the taxonomy. Questions were dichotomized into higher- and lower-order thinking questions. The inferential methods involved chi-square tests of association to determine if there were statistically significant differences among the four traditional college general chemistry textbooks in the proportions of higher- and lower-order questions and if there were statistically significant differences between the nontraditional chemistry textbook and the four traditional general chemistry textbooks. Findings indicated statistically significant differences among the four textbooks frequently used in Texas community colleges in the number of higher- and lower-level questions. Statistically significant differences were also found among the four textbooks and the nontraditional textbook. After the analysis of

Park, H W

1998-01-01

Kwang Hye Won(Je Joong Won), the first western hospital in Korea, was founded in 1885. The first western Medical School in Korea was open in 1886 under the hospital management. Dr. O. R. Avison, who came to Korea in 1893, resumed the medical education there, which was interrupted for some time before his arrival in Korea. He inaugurated translating and publishing medical textbooks with the help of Kim Pil Soon who later became one of the first seven graduates in Severance Hospital Medical School. The first western medical textbook translated into Korean was Henry Gray's Anatomy. However, these twice-translated manuscripts were never to be published on account of being lost and burnt down. The existing early anatomy textbooks, the editions of 1906 and 1909, are not the translation of Gray's Anatomy, but that of Japanese anatomy textbook of Gonda. The remaining oldest medical textbook in Korean is Inorganic Materia Medica published in 1905. This book is unique among its kind that O. R. Avison is the only translator of the book and it contains the prefaces of O. R. Avison and Kim Pil Soon. The publication of medical textbook was animated by the participation of other medical students, such as Hong Suk Hoo and Hong Jong Eun. The list of medical textbooks published includes almost all the field of medicine. The medical textbooks in actual existence are as follows: Inorganic Materia Medica (1905), Inorganic Chemistry (1906), Anatomy I (1906), Physiology (1906), Diagnostics I (1906), Diagnostics II (1907), Obstetrics (1908), Organic Chemistry (1909), Anatomy (1909), and Surgery (1910).

Sociology of health textbooks and narratives: historical significance.

PubMed

Nunes, Everardo Duarte

2016-03-01

This article has as its starting point two central ideas: textbooks as a means of production and dissemination of knowledge and narrative as an approach. After a brief review of studies on health/medical sociology textbooks, I analyze a few of these textbooks from the 1900-2012 period, produced in the United States and England. I have selected eleven textbooks which I thought were representative. In addition to a content analysis, the textbooks are located within the process of constitution of the health/medical sociology with brief references to the biographies of the authors. The textbooks analyzed were classified according to the main narrative features: doctor-centered; interdisciplinary; pedagogical; analytical; almost autobiographical; critical; and synthetic-reflective. In the final remarks, some points about the textbooks, limits and possibilities are presented.

Modelling Fault Zone Evolution: Implications for fluid flow.

NASA Astrophysics Data System (ADS)

Moir, H.; Lunn, R. J.; Shipton, Z. K.

2009-04-01

Flow simulation models are of major interest to many industries including hydrocarbon, nuclear waste, sequestering of carbon dioxide and mining. One of the major uncertainties in these models is in predicting the permeability of faults, principally in the detailed structure of the fault zone. Studying the detailed structure of a fault zone is difficult because of the inaccessible nature of sub-surface faults and also because of their highly complex nature; fault zones show a high degree of spatial and temporal heterogeneity i.e. the properties of the fault change as you move along the fault, they also change with time. It is well understood that faults influence fluid flow characteristics. They may act as a conduit or a barrier or even as both by blocking flow across the fault while promoting flow along it. Controls on fault hydraulic properties include cementation, stress field orientation, fault zone components and fault zone geometry. Within brittle rocks, such as granite, fracture networks are limited but provide the dominant pathway for flow within this rock type. Research at the EU's Soultz-sous-Forệt Hot Dry Rock test site [Evans et al., 2005] showed that 95% of flow into the borehole was associated with a single fault zone at 3490m depth, and that 10 open fractures account for the majority of flow within the zone. These data underline the critical role of faults in deep flow systems and the importance of achieving a predictive understanding of fault hydraulic properties. To improve estimates of fault zone permeability, it is important to understand the underlying hydro-mechanical processes of fault zone formation. In this research, we explore the spatial and temporal evolution of fault zones in brittle rock through development and application of a 2D hydro-mechanical finite element model, MOPEDZ. The authors have previously presented numerical simulations of the development of fault linkage structures from two or three pre-existing joints, the results of

Representation of scientific methodology in secondary science textbooks

NASA Astrophysics Data System (ADS)

Binns, Ian C.

The purpose of this investigation was to assess the representation of scientific methodology in secondary science textbooks. More specifically, this study looked at how textbooks introduced scientific methodology and to what degree the examples from the rest of the textbook, the investigations, and the images were consistent with the text's description of scientific methodology, if at all. The sample included eight secondary science textbooks from two publishers, McGraw-Hill/Glencoe and Harcourt/Holt, Rinehart & Winston. Data consisted of all student text and teacher text that referred to scientific methodology. Second, all investigations in the textbooks were analyzed. Finally, any images that depicted scientists working were also collected and analyzed. The text analysis and activity analysis used the ethnographic content analysis approach developed by Altheide (1996). The rubrics used for the text analysis and activity analysis were initially guided by the Benchmarks (AAAS, 1993), the NSES (NRC, 1996), and the nature of science literature. Preliminary analyses helped to refine each of the rubrics and grounded them in the data. Image analysis used stereotypes identified in the DAST literature. Findings indicated that all eight textbooks presented mixed views of scientific methodology in their initial descriptions. Five textbooks placed more emphasis on the traditional view and three placed more emphasis on the broad view. Results also revealed that the initial descriptions, examples, investigations, and images all emphasized the broad view for Glencoe Biology and the traditional view for Chemistry: Matter and Change. The initial descriptions, examples, investigations, and images in the other six textbooks were not consistent. Overall, the textbook with the most appropriate depiction of scientific methodology was Glencoe Biology and the textbook with the least appropriate depiction of scientific methodology was Physics: Principles and Problems.

D'Alessandro, D M; Kreiter, C D; Erkonen, W E; Winter, R J; Knapp, H R

1997-11-01

The goal of this prospective, interinstitutional study was to compare the long-term instructional effectiveness of a pediatric multimedia textbook (MMTB) to that of a standard lecture and a printed textbook. A randomized cohort of 89 3rd-year medical students from two institutions were initially evaluated from June 1992 to June 1993 and reevaluated in May 1994. Students were randomly assigned to one of four instructional groups: computer-aided instruction by means of MMTBs (n = 21), traditional lecture (n = 23), printed textbook (n = 19), and a control group (n = 26). After instruction, all groups were tested by means of a multiple choice test at the end of their pediatric clerkship; they were given this same test 11-22 months later. The long-term instructional effectiveness of the MMTB, printed textbook, and lecture were the same as that in the control group, as determined by analysis of variance of mean test scores. The educational advantage of MMTBs observed immediately after instruction was not detected 1 year later. Because attrition reduced statistical power, further research is necessary to determine how educational fading affects these instructional formats.

Breastfeeding information in pharmacology textbooks: a content analysis.

PubMed

Amir, Lisa H; Raval, Manjri; Hussainy, Safeera Y

2013-07-01

Women often need to take medicines while breastfeeding and pharmacists need to provide accurate information in order to avoid undue caution about the compatibility of medicines and breastfeeding. The objective of this study was to review information provided about breastfeeding in commonly used pharmacology textbooks. We asked 15 Australian universities teaching pharmacy courses to provide a list of recommended pharmacology textbooks in 2011. Ten universities responded, generating a list of 11 textbooks that we analysed for content relating to breastfeeding. Pharmacology textbooks outline the mechanisms of actions of medicines and their use: however, only a small emphasis is placed on the safety/compatibility of medicines for women during breastfeeding. Current pharmacology textbooks recommended by Australian universities have significant gaps in their coverage of medicine use in breastfeeding. Authors of textbooks should address this gap, so academic staff can recommend texts with the best lactation content.

Evaluating Junior Secondary Science Textbook Usage in Australian Schools

NASA Astrophysics Data System (ADS)

McDonald, Christine V.

2016-08-01

A large body of research has drawn attention to the importance of providing engaging learning experiences in junior secondary science classes, in an attempt to attract more students into post-compulsory science courses. The reality of time and resource constraints, and the high proportion of non-specialist science teachers teaching science, has resulted in an overreliance on more transmissive pedagogical tools, such as textbooks. This study sought to evaluate the usage of junior secondary science textbooks in Australian schools. Data were collected via surveys from 486 schools teaching junior secondary (years 7-10), representing all Australian states and territories. Results indicated that most Australian schools use a science textbook in the junior secondary years, and textbooks are used in the majority of science lessons. The most highly cited reason influencing choice of textbook was layout/colour/illustrations, and electronic technologies were found to be the dominant curricula material utilised, in addition to textbooks, in junior secondary science classes. Interestingly, the majority of respondents expressed high levels of satisfaction with their textbooks, although many were keen to stress the subsidiary role of textbooks in the classroom, emphasising the textbook was `one' component of their teaching repertoire. Importantly, respondents were also keen to stress the benefits of textbooks in supporting substitute teachers, beginning teachers, and non-specialist science teachers; in addition to facilitating continuity of programming and staff support in schools with high staff turnover. Implications from this study highlight the need for high quality textbooks to support teaching and learning in Australian junior secondary science classes.

Neotectonic reactivation of shear zones and implications for faulting style and geometry in the continental margin of NE Brazil

Bezerra, F. H. R.; Rossetti, D. F.; Oliveira, R. G.; Medeiros, W. E.; Neves, B. B. Brito; Balsamo, F.; Nogueira, F. C. C.; Dantas, E. L.; Andrades Filho, C.; Góes, A. M.

2014-02-01

The eastern continental margin of South America comprises a series of rift basins developed during the breakup of Pangea in the Jurassic-Cretaceous. We integrated high resolution aeromagnetic, structural and stratigraphic data in order to evaluate the role of reactivation of ductile, Neoproterozoic shear zones in the deposition and deformation of post-rift sedimentary deposits in one of these basins, the Paraíba Basin in northeastern Brazil. This basin corresponds to the last part of the South American continent to be separated from Africa during the Pangea breakup. Sediment deposition in this basin occurred in the Albian-Maastrichtian, Eocene-Miocene, and in the late Quaternary. However, our investigation concentrates on the Miocene-Quaternary, which we consider the neotectonic period because it encompasses the last stress field. This consisted of an E-W-oriented compression and a N-S-oriented extension. The basement of the basin forms a slightly seaward-tilted ramp capped by a late Cretaceous to Quaternary sedimentary cover ~ 100-400 m thick. Aeromagnetic lineaments mark the major steeply-dipping, ductile E-W- to NE-striking shear zones in this basement. The ductile shear zones mainly reactivated as strike-slip, normal and oblique-slip faults, resulting in a series of Miocene-Quaternary depocenters controlled by NE-, E-W-, and a few NW-striking faults. Faulting produced subsidence and uplift that are largely responsible for the present-day morphology of the valleys and tablelands in this margin. We conclude that Precambrian shear zone reactivation controlled geometry and orientation, as well as deformation of sedimentary deposits, until the Neogene-Quaternary.

Cascadia Subduction Zone

USGS Publications Warehouse

Frankel, Arthur D.; Petersen, Mark D.

2008-01-01

The geometry and recurrence times of large earthquakes associated with the Cascadia Subduction Zone (CSZ) were discussed and debated at a March 28-29, 2006 Pacific Northwest workshop for the USGS National Seismic Hazard Maps. The CSZ is modeled from Cape Mendocino in California to Vancouver Island in British Columbia. We include the same geometry and weighting scheme as was used in the 2002 model (Frankel and others, 2002) based on thermal constraints (Fig. 1; Fluck and others, 1997 and a reexamination by Wang et al., 2003, Fig. 11, eastern edge of intermediate shading). This scheme includes four possibilities for the lower (eastern) limit of seismic rupture: the base of elastic zone (weight 0.1), the base of transition zone (weight 0.2), the midpoint of the transition zone (weight 0.2), and a model with a long north-south segment at 123.8? W in the southern and central portions of the CSZ, with a dogleg to the northwest in the northern portion of the zone (weight 0.5). The latter model was derived from the approximate average longitude of the contour of the 30 km depth of the CSZ as modeled by Fluck et al. (1997). A global study of the maximum depth of thrust earthquakes on subduction zones by Tichelaar and Ruff (1993) indicated maximum depths of about 40 km for most of the subduction zones studied, although the Mexican subduction zone had a maximum depth of about 25 km (R. LaForge, pers. comm., 2006). The recent inversion of GPS data by McCaffrey et al. (2007) shows a significant amount of coupling (a coupling factor of 0.2-0.3) as far east as 123.8? West in some portions of the CSZ. Both of these lines of evidence lend support to the model with a north-south segment at 123.8? W.

Usability of PDF based Digital Textbooks to the Physically Disabled University Student.

PubMed

Oku, Hidehisa; Matsubara, Kayoko; Booka, Masayuki

2015-01-01

Digital textbooks have been expected for providing multimedia information that the print textbooks could not handle. The original digital textbook can be fabricated relatively easily by using Epub or DAISY. Print textbooks are, however, employed as textbooks in the most of lectures in universities. Therefore, it is considered necessary to convert the content of the print textbook to the digital textbook simply and in a short time. In this paper, the digital textbook using PDF files of the print textbook was suggested as one of simple and practical solution to provide an alternative textbook for the physically disabled university student who has difficulty handling the print textbook. Then usability of the suggested method was evaluated experimentally from the point of workload. Result of the experiment indicates that the digital textbook fabricated as the alternative one for the print textbook by the suggested method has a potential to reduce workload for the physically disabled university students. In addition, the digital textbook with larger LCD display needs less workload than the print textbook. Then, there are not so much difference in the workload between the print book which is smaller than the print textbook and the digital book made from the print book.

Fujiyoshi, Akio; Ohsawa, Akiko; Takaira, Takuya; Tani, Yoshiaki; Fujiyoshi, Mamoru; Ota, Yuko

2015-01-01

Utilizing invisible 2-dimensional codes and digital audio players with a 2-dimensional code scanner, we developed paper-based textbooks with audio support for students with print disabilities, called "multimodal textbooks." Multimodal textbooks can be read with the combination of the two modes: "reading printed text" and "listening to the speech of the text from a digital audio player with a 2-dimensional code scanner." Since multimodal textbooks look the same as regular textbooks and the price of a digital audio player is reasonable (about 30 euro), we think multimodal textbooks are suitable for students with print disabilities in ordinary classrooms.

Textbooks vs. techbooks: Effectiveness of digital textbooks on elementary student motivation for learning

NASA Astrophysics Data System (ADS)

Oman, Auna

This action research project investigated fourth grade students¡¦ motivation to learn science using a digital science techbook. Participants in the study included 29 fourth grade students in two different classrooms. One classroom of 16 students used a digital science techbook to learn science while the other classroom of 13 students used a traditional paper science textbook to learn science. Students in both classrooms answered five sets of questions regarding their experience using a digital science techbook and a paper science techbook to understand science, find science information, solve science problems, learn science, and assess learning science was fun. Results were compiled and coded based on positive and negative responses to conditions. A chi-square was used to analyze the ordinal data. Overall differences between techbooks vs. textbook were significant, X2 (1, N = 29) = 23.84, p = .000, justifying further examination of individual survey items. Three items had statistically significant difference for finding science information, solving science problems, and learning science. A gender difference was also found in one item. Females preferred to use paper science textbooks to understand science, while males preferred digital techbooks to learn science. The fourth graders in this study indicated that digital techbooks were a powerful learning tool for increasing interest, excitement and learning science. Even though students reported paper science textbooks as easy to use, they found using digital science techbooks a far more appealing way to learn science.

Modeling the Geometry of Plate Boundary and Seismic Structure in the Southern Ryukyu Trench Subduction Zone, Japan, Using Amphibious Seismic Observations

Yamamoto, Y.; Takahashi, T.; Ishihara, Y.; Kaiho, Y.; Arai, R.; Obana, K.; Nakanishi, A.; Miura, S.; Kodaira, S.; Kaneda, Y.

2018-02-01

Here we present the new model, the geometry of the subducted Philippine Sea Plate interface beneath the southern Ryukyu Trench subduction zone, estimated from seismic tomography and focal mechanism estimation by using passive and active data from a temporary amphibious seismic network and permanent land stations. Using relocated low-angle thrust-type earthquakes, repeating earthquakes, and structural information, we constrained the geometry of plate boundary from the trench axis to a 60 km depth with uncertainties of less than 5 km. The estimated plate geometry model exhibited large variation, including a pronounced convex structure that may be evidence of a subducted seamount in the eastern portion of study area, whereas the western part appeared smooth. We also found that the active earthquake region near the plate boundary, defined by the distance from our plate geometry model, was clearly separated from the area dominated by short-term slow-slip events (SSEs). The oceanic crust just beneath the SSE-dominant region, the western part of the study area, showed high Vp/Vs ratios (>1.8), whereas the eastern side showed moderate or low Vp/Vs (<1.75). We interpreted this as an indication that high fluid pressures near the surface of the slab are contributing to the SSE activities. Within the toe of the mantle wedge, P and S wave velocities (<7.5 and <4.2 km/s, respectively) lower than those observed through normal mantle peridotite might suggest that some portions of the mantle may be at least 40% serpentinized.

Relationships between sliding behavior and internal geometry of laboratory fault zones and some creeping and locked strike-slip faults of California

Moore, D.E. and Byerlee, J., 1992. Relationships between sliding behavior and internal geometry of laboratory fault zones and some creeping and locked strike-slip faults of California. In: T. Mikumo, K. Aki, M. Ohnaka, L.J. Ruff and P.K.P. Spudich (Editors), Earthquake Source Physics and Earthquake Precursors. Tectonophysics, 211: 305-316. In order to relate fault geometries to sliding behavior, maps of recently active breaks within the Hayward fault of central California, which is characterized by fault creep, have been examined and compared to maps of the San Andreas fault. The patterns of recent breaks of the Hayward fault are consistent with those found within the creeping section of the San Andreas, and they appear to have plausible physical explanations in the findings of laboratory experiments. The distinguishing geometric features of the examined locked and creeping faults are: (1) P-type second-order traces predominate over R(Riedel)-type traces in creeping sections; and (2) R-type second-order traces make smaller angles to the local fault strike in creeping sections than they do in locked sections. Two different maps of the Hayward fault gave similar results, supporting the inference that the patterns identified are basic characteristics of the fault rather than artifacts of a particular mapping procedure. P shears predominate over R shears under laboratory conditions that allow dilation within the fault zone. In our own experiments, P-shear development was favored by the generation of excess pore-fluid pressures. We propose that creep in California faults also is the result of fluid overpressures that are maintained in a low-permeability gouge zone and that significantly lower effective stresses, thus helping to stabilize slip and producing high values of the ratio P/R. Small R-trace angles may also be an indicator of low effective stresses, but the evidence for this is not conclusive because other factors can also affect the size of the angles. ?? 1992.

Granular flows in constrained geometries

NASA Astrophysics Data System (ADS)

Murthy, Tejas; Viswanathan, Koushik

Confined geometries are widespread in granular processing applications. The deformation and flow fields in such a geometry, with non-trivial boundary conditions, determine the resultant mechanical properties of the material (local porosity, density, residual stresses etc.). We present experimental studies of deformation and plastic flow of a prototypical granular medium in different nontrivial geometries- flat-punch compression, Couette-shear flow and a rigid body sliding past a granular half-space. These geometries represent simplified scaled-down versions of common industrial configurations such as compaction and dredging. The corresponding granular flows show a rich variety of flow features, representing the entire gamut of material types, from elastic solids (beam buckling) to fluids (vortex-formation, boundary layers) and even plastically deforming metals (dead material zone, pile-up). The effect of changing particle-level properties (e.g., shape, size, density) on the observed flows is also explicitly demonstrated. Non-smooth contact dynamics particle simulations are shown to reproduce some of the observed flow features quantitatively. These results showcase some central challenges facing continuum-scale constitutive theories for dynamic granular flows.

Results of a Textbook Survey Given in Introductory Astronomy

NASA Astrophysics Data System (ADS)

Willoughby, Shannon

2007-05-01

Textbooks are required for virtually all college science courses taught around the country, but whether students use them and find them valuable is not clear. In order to get a better idea about what the students thought of the textbook and how they spent their time using it, an anonymous survey was taken by 305 (out of 400) students enrolled in Physics 101 during the Fall semester of 2005. Developed and administered by www.textrev.com, this is a free survey that college faculty may use for physics and chemistry textbooks. This survey revealed two interesting points. First, although 75% of the students found the textbook to be moderately to very challenging, only 38% of students reported spending 2 or more hours per week reading the text. Reading was assigned the majority of class periods, with the intention that they would read the material before it was covered in class. Second, 81% of the students found that the end of chapter problems were moderately to very challenging, but 62% reported spending one hour or less per week working on the assigned questions. Homework was assigned regularly from the textbook for the first half of the class, after which point we experimented with an online homework system. Next semester a new textbook is being adopted for this class, which has no color pictures and is significantly slimmer than the current textbook. This textbook survey will be given again at the end of next semester to look for any changes in textbook usage.

Sex division of labour in Syrian school textbooks

NASA Astrophysics Data System (ADS)

Alrabaa, Sami

1985-12-01

The sexist division of labour, particularly in the occupational sector, which is believed to be more eminent in developing countries than in the developed ones, is reinforced by school textbooks. This state of affairs is hampering sex-role equality on the way to emancipation. Various Syrian school textbooks have been scrutinized and proved to be malebiased in content and language. Despite quantitative growth of education, the emancipatory quality of the school textbooks leaves much to be desired. The government has had the chance since 1963 to produce textbooks conductive to its promise of sex-role equality in education. The textbooks portray males for a bustling world of decision making, while conditioning the females to seek fulfilment in the background where servitude and support are the only requirement. Females are derogated and victimized. These contents, which are internalized at school and reproduced in society, certainly do not serve development. The exclusion of one-half of the population from contributing to the tasks of development is a waste of human talent which no society can afford. Furthermore, the sexist portrayal of females in Syrian textbooks is a pale reflection of Arab women in Arab history and literature.

Motivating students to read the textbook before class

NASA Astrophysics Data System (ADS)

Pepper, Rachel E.

2016-11-01

Many faculty in STEM courses assign textbook reading in advance of lecture, yet evidence shows few students actually read the textbook. Those students that do read often do so only after the material has been presented in class. Preparing for class by reading the textbook beforehand improves student learning and is particularly critical for classes that employ active engagement strategies. Here I present strategies I have used to successfully motivate my students to read the textbook before class in physics classes ranging from introductory algebra-based physics to advanced courses for physics majors. In the introductory course, I used pre-class reading quizzes, a common strategy that has been shown effective in previous studies, but one that is somewhat time-consuming to implement. In my more advanced courses I used reading reflections, which required considerably less time. While it was typical for less than 25% of students to read the textbook before I implemented reading quizzes or reflections, after implementing these strategies 70-90% of students reported reading the textbook before class most of the time. Students also report finding both the readings themselves and the quizzes and reflections valuable for their learning.

Scientific explanations in Greek upper secondary physics textbooks

NASA Astrophysics Data System (ADS)

Velentzas, Athanasios; Halkia, Krystallia

2018-01-01

In this study, an analysis of the structure of scientific explanations included in physics textbooks of upper secondary schools in Greece was completed. In scientific explanations for specific phenomena found in the sample textbooks, the explanandum is a logical consequence of the explanans, which in all cases include at least one scientific law (and/or principle, model or rule) previously presented, as well as statements concerning a specific case or specific conditions. The same structure is also followed in most of the cases in which the textbook authors explain regularities (i.e. laws, rules) as consequences of one or more general law or principle of physics. Finally, a number of the physics laws and principles presented in textbooks are not deduced as consequences from other, more general laws, but they are formulated axiomatically or inductively derived and the authors argue for their validity. Since, as it was found, the scientific explanations presented in the textbooks used in the study have similar structures to the explanations in internationally known textbooks, the findings of the present work may be of interest not only to science educators in Greece, but also to the community of science educators in other countries.

Three-dimensional geometry and tectonostratigraphy of the Pennine zone, Central Alps, Switzerland and Northern Italy

NASA Astrophysics Data System (ADS)

Maxelon, Michael; Mancktelow, Neil S.

2005-08-01

Continental collision during Alpine orogenesis entailed a polyphase deformation history (D 1-D 5) in the Pennine zone of the Central Alps. The regional tectonostratigraphy was basically developed during D 1 and D 2, characterised by isoclinal, typically north-closing recumbent anticlines, separated by pinched-in synclines, on the scale of tens of kilometres. Later deformation phases (D 3 and D 4) warped the stack into wavy to open folds. Exhumation of this zone resulted locally in later vertical shortening and folding of already steep fabrics (D 5). Three-dimensional models of the nappe pile were constructed, based on geostatistical assessment of the regional foliation field and considering the abundant structural field data. These models indicate the existence of five principal tectonostratigraphic levels developed during D 1 and thus equivalent to nappe units s. str.: the Gotthard, the Leventina-Antigorio, the Maggia-Simano (and probably the Monte Leone as well as the Composite Lepontine Series), Lebendun-Soja and Adula-Cima Lunga levels. All these tectonic units formed part of the passive continental margin of Europe prior to the onset of the Alpine orogenesis. Individual isoclinal post-nappe folds reflect relative displacements on the order of 40 km or more. The most prominent D 2 post-nappe structure is the Wandfluhhorn Fold, structurally equivalent to the northern closure of the Leventina-Lucomagno Antiform. The Lebendun and Monte Leone folds are of similar magnitudes and also affect the whole nappe pile, whereas the smaller Mogno and Molare synforms only refold the Maggia-Simano nappe internally. Principal D 3 and D 4 structures are the tight Mergoscia Synform directly north of the Insubric Fault between Bellinzona and Locarno (Southern Steep Belt), the Maggia Steep Zone, forming the steep western limb of the Campo Tencia Synform and subdividing the Lepontine dome into the Simplon and Ticino subdomes, the Chiéra Synform steepening the dominant foliation in

Though the notion of a scientific textbook has been around for almost three centuries, the category has hardly been stable. The plasticity of the textbook genre may be illustrated by recent variations as well as long-term trends. In this brief essay I examine two idiosyncratic but highly successful physics books, each published in the mid 1970s, whose production, marketing, and adoption reveal some of the slippage between such categories as textbook, scholarly monograph, and popular best seller.

Conceptual Variation or Incoherence? Textbook Discourse on Genes in Six Countries

NASA Astrophysics Data System (ADS)

Gericke, Niklas M.; Hagberg, Mariana; dos Santos, Vanessa Carvalho; Joaquim, Leyla Mariane; El-Hani, Charbel N.

2014-02-01

The aim of this paper is to investigate in a systematic and comparative way previous results of independent studies on the treatment of genes and gene function in high school textbooks from six different countries. We analyze how the conceptual variation within the scientific domain of Genetics regarding gene function models and gene concepts is transformed via the didactic transposition into school science textbooks. The results indicate that a common textbook discourse on genes and their function exist in textbooks from the different countries. The structure of science as represented by conceptual variation and the use of multiple models was present in all the textbooks. However, the existence of conceptual variation and multiple models is implicit in these textbooks, i.e., the phenomenon of conceptual variation and multiple models are not addressed explicitly, nor its consequences and, thus, it ends up introducing conceptual incoherence about the gene concept and its function within the textbooks. We conclude that within the found textbook-discourse ontological aspects of the academic disciplines of genetics and molecular biology were retained, but without their epistemological underpinnings; these are lost in the didactic transposition. These results are of interest since students might have problems reconstructing the correct scientific understanding from the transformed school science knowledge as depicted within the high school textbooks. Implications for textbook writing as well as teaching are discussed in the paper.

Social issues in high school biology textbooks: 1963- 1983

NASA Astrophysics Data System (ADS)

Rosenthal, Dorothy B.

Twenty-two high school biology textbooks published between 1963 and 1983 were analyzed for their treatment of social issues. Textbooks were selected from among those used most frequently by teachers and/or having the highest sales. The textbooks were read in random order and the amount of space, to the nearest tenth of a page, devoted to each social issue was expressed as a percentage of total length of text. The results showed that attention to social issues decreased between 1963 and 1983 in the textbooks studied. The implications of these results for biology education in the 1980s are discussed.

Comparing the development of the multiplication of fractions in Turkish and American textbooks

Kar, Tuğrul; Güler, Gürsel; Şen, Ceylan; Özdemir, Ercan

2018-02-01

This study analyzed the methods used to teach the multiplication of fractions in Turkish and American textbooks. Two Turkish textbooks and two American textbooks, Everyday Mathematics (EM) and Connected Mathematics 3 (CM), were analyzed. The analyses focused on the content and the nature of the mathematical problems presented in the textbooks. The findings of the study showed that the American textbooks aimed at developing conceptual understanding first and then procedural fluency, whereas the Turkish textbooks aimed at developing both concurrently. The American textbooks provided more opportunities for different computational strategies. The solutions to most problems in all textbooks required a single computational step, a numerical answer, and procedural knowledge. Furthermore, compared with the Turkish textbooks, the American textbooks contained a greater number of problems that required high-level cognitive skills such as mathematical reasoning.

Towards an Intelligent Textbook of Neurology

PubMed Central

Reggia, James A.; Pula, Thaddeus P.; Price, Thomas R.; Perricone, Barry T.

1980-01-01

We define an intelligent textbook of medicine to be a computer system that: (1) provides for storage and selective retrieval of synthesized clinical knowledge for reference purposes; and (2) supports the application by computer of its knowledge to patient information to assist physicians with decision making. This paper describes an experimental system called KMS (a Knowledge Management System) for creating and using intelligent medical textbooks. KMS is domain-independent, supports multiple inference methods and representation languages, and is designed for direct use by physicians during the knowledge acquisition process. It is presented here in the context of the development of an Intelligent Textbook of Neurology. We suggest that KMS has the potential to overcome some of the problems that have inhibited the use of knowledge-based systems by physicians in the past.

Inferring rupture characteristics using new databases for 3D slab geometry and earthquake rupture models

NASA Astrophysics Data System (ADS)

Hayes, G. P.; Plescia, S. M.; Moore, G.

2017-12-01

The U.S. Geological Survey National Earthquake Information Center has recently published a database of finite fault models for globally distributed M7.5+ earthquakes since 1990. Concurrently, we have also compiled a database of three-dimensional slab geometry models for all global subduction zones, to update and replace Slab1.0. Here, we use these two new and valuable resources to infer characteristics of earthquake rupture and propagation in subduction zones, where the vast majority of large-to-great-sized earthquakes occur. For example, we can test questions that are fairly prevalent in seismological literature. Do large ruptures preferentially occur where subduction zones are flat (e.g., Bletery et al., 2016)? Can `flatness' be mapped to understand and quantify earthquake potential? Do the ends of ruptures correlate with significant changes in slab geometry, and/or bathymetric features entering the subduction zone? Do local subduction zone geometry changes spatially correlate with areas of low slip in rupture models (e.g., Moreno et al., 2012)? Is there a correlation between average seismogenic zone dip, and/or seismogenic zone width, and earthquake size? (e.g., Hayes et al., 2012; Heuret et al., 2011). These issues are fundamental to the understanding of earthquake rupture dynamics and subduction zone seismogenesis, and yet many are poorly understood or are still debated in scientific literature. We attempt to address these questions and similar issues in this presentation, and show how these models can be used to improve our understanding of earthquake hazard in subduction zones.

Medical textbooks are an important teaching supplement. Few have junior doctors or medical students ('juniors') as primary contributors. However, the strengths of junior-led face-to-face teaching are now well-established, and we hypothesized that similar advantages would be transferrable to a textbook setting. Juniors were approached to contribute to an independently published medical textbook, with senior clinicians recruited in parallel to ensure factual accuracy. Juniors directed every aspect of textbook writing and the production process. The published book stressed that it was an open collaboration with readers, inviting them to get in touch to evaluate the text and suggest ideas for new titles. Of 75 respondents, 93 % awarded the first textbook in the series 4 or 5 out of 5 for overall quality. Five other titles have been released, with seven more in development. Over 100 juniors are currently involved, with two students progressing from reviewers to editors after less than a year of mentorship. Juniors can be a motivated, dynamic, innovative group, capable of significant contributions to the medical textbook literature. This initiative has generated a sustainable infrastructure to facilitate junior-led publishing, and has the capacity for expansion to accommodate new initiatives and ideas.

Between training and popularization: Regulating science textbooks in secondary education.

PubMed

Shapiro, Adam R

2012-03-01

Recruitment into the scientific community is one oft-stated goal of science education--in the post-Sputnik United States, for example--but this obscures the fact that science textbooks are often read by people who will never be scientists. It cannot be presupposed that science textbooks for younger audiences, students in primary and secondary schools, function in this way. For this reason, precollegiate-level science textbooks are sometimes discussed as a subset of literature popularizing science. The high school science classroom and the textbook are forums for exposing the public to science. The role of governments and educational institutions in regulating the consumption of these texts not only determines which books are used; it influences how they are written, read, and deemed authoritative. Therefore such science textbooks should not be seen as (at best) the disjunction of texts-for-training and books-for-popularization. A changing sense of what "textbooks" are compels a different understanding of their use in the history of science.

Understanding textbook quality in the USA: How governments distort the market

NASA Astrophysics Data System (ADS)

Oliveira, João Batista

1995-11-01

Textbooks deliver education and shape the daily routines of classrooms. Even in countries where schools enjoy ample and various instructional resources, text-books are the single most important support for teachers and students. It is not surprising, then, that textbooks are a major concern of states, schools, teachers, parents, publishers, and the research community. But textbooks often become a scapegoat for educational evils. In the USA, government regulation, special interest groups, and publishers exert pressure on textbook policies and state and local adoption processes. The result: textbooks are published to conform to a market distorted by government regulation. This paper discusses how their quality is constrained by government and special interest groups that interfere with the natural course of regulations and markets.

This article aims to provide an overview of the historiography of psychology textbooks. In the overview, I identify and describe in detail two strands of writing histories of introductory textbooks of psychology and juxtapose them to provide an integrated historiography of textbooks in psychology. One strand is developed by teachers of psychology—first as a general approach for investigating textbooks in a pedagogical setting, and then later upgraded into a full history of psychology textbooks in America. The other strand follows a more familiar perspective of historians of science and historians of psychology who build on various post‐Kuhnian and post‐Foucauldian perspectives on textbooks. I make an argument for integrating these two views for a more comprehensive historiography of textbooks in psychology, recasting textbooks as objects of research and sources that are interesting sui generis for historians of psychology in their investigations.

Misrepresentations of evolutionary psychology in sex and gender textbooks.

PubMed

Winegard, Benjamin M; Winegard, Bo M; Deaner, Robert O

2014-05-20

Evolutionary psychology has provoked controversy, especially when applied to human sex differences. We hypothesize that this is partly due to misunderstandings of evolutionary psychology that are perpetuated by undergraduate sex and gender textbooks. As an initial test of this hypothesis, we develop a catalog of eight types of errors and document their occurrence in 15 widely used sex and gender textbooks. Consistent with our hypothesis, of the 12 textbooks that discussed evolutionary psychology, all contained at least one error, and the median number of errors was five. The most common types of errors were "Straw Man," "Biological Determinism," and "Species Selection." We conclude by suggesting improvements to undergraduate sex and gender textbooks.

PubMed

Ayello, Elizabeth A; Meaney, Geraldine

2003-09-01

Nurses enter the profession with knowledge about pressure ulcer prevention and care and acquired from their basic educational programs. A prior review of nursing textbooks regarding pressure ulcer content published almost a decade ago revealed that incomplete, inaccurate, and at times limited information (as few as 200 lines of text) was contained in 10 commonly used textbooks. A review of the updated editions of the textbooks revealed a wide variation in the number of lines of text devoted to pressure ulcers, depth and quality of information, and the number of illustrations and tables. New findings were the inclusion of cultural concepts and research studies. These findings suggest an improvement in the amount and quality of pressure ulcer information in the majority of nursing textbooks surveyed. Recommendations for future textbook chapters on pressure ulcers are provided.

Replacing textbook problems with lab experiences

NASA Astrophysics Data System (ADS)

Register, Trevor

2017-10-01

End-of-the-chapter textbook problems are often the bread and butter of any traditional physics classroom. However, research strongly suggests that students be given the opportunity to apply their knowledge in multiple contexts as well as be provided with opportunities to do the process of science through laboratory experiences. Little correlation has been shown linking the number of textbook problems solved with conceptual understanding of topics in mechanics. Furthermore, textbook problems as the primary source of practice for students robs them of the joy and productive struggle of learning how to think like an experimental physicist. Methods such as Modeling Instruction tackle this problem head-on by starting each instructional unit with an inquiry-based lab aimed at establishing the important concepts and equations for the unit, and this article will discuss ideas and experiences for how to carry that philosophy throughout a unit.

An innovative textbook: design and implementation.

Ortega, Rafael; Akhtar-Khavari, Vafa; Barash, Paul; Sharar, Sam; Stock, M Christine

2017-12-01

The 'flipped classroom' instructional strategy has gained much momentum in educational discourse, yet no single educational offering exists in postgraduate medical education (PME) to systematically replace the lecture element of didactic sessions. This article describes the design and implementation of Clinical Anesthesia Fundamentals, the first known textbook in PME addressing this gap in resources through the integration of full-length interactive multimedia-enhanced video lectures. The 'flipped classroom' instructional strategy has gained much momentum in educational discourse INNOVATION: The textbook was developed in alignment with the content outline for the specialty provided by the American Board of Anesthesiology. Its accompanying video lectures, produced at the Media Lab in the Department of Anesthesiology at Boston University Medical Center (BUMC), cover the topics in each chapter of the textbook and include review questions featuring explanatory feedback. Following a 5-month trial period at the BUMC Anesthesiology Residency Program, the complete resident class (25 of 25; 100%) participated in an anonymous, Institutional Review Board (IRB) -approved, five-point Likert-type scale survey assessing an underlying variable of preference for the use of multimedia learning tools. Survey results suggest that residents favour technology-enhanced learning environments in which textbooks are coupled with interactive multimedia, and the 'flipped classroom' approach is employed. Although the development of digital videos requires time and financial investment, the improved accessibility and uniform delivery of didactic content are two positive outcomes. This textbook provides an example for educators wishing to learn how to capitalise on advances in technology to further enhance learning and accessibility. Further studies could address the impact of this approach on the academic performance of residents. © 2016 John Wiley & Sons Ltd and The Association for the Study

Quantum geometry of resurgent perturbative/nonperturbative relations

NASA Astrophysics Data System (ADS)

Basar, Gökçe; Dunne, Gerald V.; Ünsal, Mithat

2017-05-01

For a wide variety of quantum potentials, including the textbook `instanton' examples of the periodic cosine and symmetric double-well potentials, the perturbative data coming from fluctuations about the vacuum saddle encodes all non-perturbative data in all higher non-perturbative sectors. Here we unify these examples in geometric terms, arguing that the all-orders quantum action determines the all-orders quantum dual action for quantum spectral problems associated with a classical genus one elliptic curve. Furthermore, for a special class of genus one potentials this relation is particularly simple: this class includes the cubic oscillator, symmetric double-well, symmetric degenerate triple-well, and periodic cosine potential. These are related to the Chebyshev potentials, which are in turn related to certain \\mathcal{N} = 2 supersymmetric quantum field theories, to mirror maps for hypersurfaces in projective spaces, and also to topological c = 3 Landau-Ginzburg models and `special geometry'. These systems inherit a natural modular structure corresponding to Ramanujan's theory of elliptic functions in alternative bases, which is especially important for the quantization. Insights from supersymmetric quantum field theory suggest similar structures for more complicated potentials, corresponding to higher genus. Our approach is very elementary, using basic classical geometry combined with all-orders WKB.

Shear zone junctions: Of zippers and freeways

NASA Astrophysics Data System (ADS)

Passchier, Cees W.; Platt, John P.

2017-02-01

Ductile shear zones are commonly treated as straight high-strain domains with uniform shear sense and characteristic curved foliation trails, bounded by non-deforming wall rock. Many shear zones, however, are branched, and if movement on such branches is contemporaneous, the resulting shape can be complicated and lead to unusual shear sense arrangement and foliation geometries in the wall rock. For Y-shaped shear zone triple junctions with three joining branches and transport direction at a high angle to the branchline, only eight basic types of junction are thought to be stable and to produce significant displacement. The simplest type, called freeway junctions, have similar shear sense in all three branches. The other types show joining or separating behaviour of shear zone branches similar to the action of a zipper. Such junctions may have shear zone branches that join to form a single branch (closing zipper junction), or a single shear zone that splits to form two branches, (opening zipper junction). All categories of shear zone junctions show characteristic foliation patterns and deflection of markers in the wall rock. Closing zipper junctions are unusual, since they form a non-active zone with opposite deflection of foliations in the wall rock known as an extraction fault or wake. Shear zipper junctions can form domains of overprinting shear sense along their flanks. A small and large field example are given from NE Spain and Eastern Anatolia. The geometry of more complex, 3D shear zone junctions with slip parallel and oblique to the branchline is briefly discussed.

End-of-life care content in 50 textbooks from multiple specialties.

2000-02-09

Prior reviews of small numbers of medical textbooks suggest that end-of-life care is not well covered in textbooks. No broad study of end-of-life care content analysis has been performed on textbooks across a wide range of medical, pediatric, psychiatric, and surgical specialties. To determine the quantity and rate the adequacy of information on end-of-life care in textbooks from multiple medical disciplines. DESIGN AND SOURCES: A 1998 review of 50 top-selling textbooks from multiple specialties (cardiology, emergency medicine, family and primary care medicine, geriatrics, infectious disease and acquired immunodeficiency syndrome [AIDS], internal medicine, neurology, oncology and hematology, pediatrics, psychiatry, pulmonary medicine, and surgery) for the presence and adequacy of content in 13 end-of-life care domains. Chapters on diseases commonly causing death and those devoted to end-of-life care were identified, read, rated, and compared by textbook specialty, chapter, and domain for the presence of helpful information in the 13 domains. Content for each domain was rated as absent, minimally present, or helpful. Textbook indexes were analyzed for the number of pages relevant to end-of-life care. Overall, helpful information was provided in 24.1% (range, 8.7%-44.2%) of the expected end-of-life content domains; in 19.1% (range, 6.2%-38.5%), expected content received minimal attention; and in 56.9% (range, 23.1 %-77.9%), expected content was absent. As a group, the textbooks with the highest percentages of absent content were in surgery (71.8%), infectious diseases and AIDS (70%), and oncology and hematology (61.9%). Textbooks with the highest percentage of helpful end-of-life care content were in family medicine (34.4%), geriatrics (34.4%), and psychiatry (29.6%). In internal medicine textbooks, the content domains with the greatest amount of helpful information were epidemiology and natural history. Content domains covered least well were social, spiritual

Teachers' selection and enactment of mathematical problems from textbooks

NASA Astrophysics Data System (ADS)

Son, Ji-Won; Kim, Ok-Kyeong

2015-12-01

In order to investigate how teachers' use of textbooks creates different kinds of opportunities for student learning, this study focused on teachers' selection and enactment of problems and tasks from the textbooks and their influence on the cognitive demand placed on students. By drawing on data from three elementary teachers in the USA, two of which used a reform-oriented textbook— Math Trailblazers and one a commercially developed textbook—this study examined kinds of problems the teachers chose and ways in which they enacted those problems in relation to the cognitive demand of the problems. In particular, we attended to the kinds of questions the teachers asked in enacting the problems and ways in which those questions influenced the cognitive demand of the textbook problems. This study also identified critical issues involved in teacher decision-making on task selection and enactment, such as the match between teachers' goals and those of the textbooks, and teachers' perception of textbook problems. Based on the results of the study, we discuss implications for teacher education and professional development.

2016-01-01

Quoting an article in well-known textbooks is held as a credit for that paper. The numbers of Iranian publications mentioned in endodontic textbooks have increased during recent years. The aim of this investigation was to evaluate the number of Iranian articles quoted in eminent endodontic textbooks. Three known textbooks (Ingle's Endodontics, Seltzer and Bender's Dental Pulp and Cohen's Pathways of the Pulp) were chosen and all the editions of the textbooks since 2000 were investigated for quoted Iranian publications. Only Iranian authors with affiliations from a domestic university were chosen. All references at the end of each chapter were read by hand searching, and results were noted. The trend and percentage of Iranian publications in different editions of the textbooks were also calculated. The number of citations of these publications in Google Scholar and Scopus databases were also obtained. The number of Iranian publications in all well-known textbooks have notably increased since 2000. The number and percentage of Iranian publications in the latest edition of Cohen's Pathways of the Pulp was higher compared to other textbooks as well as the previous edition of the same text. Number and percentage of Iranian publications in the field of endodontics in all three textbooks have remarkably increased since 2000.

The role of fault surface geometry in the evolution of the fault deformation zone: comparing modeling with field example from the Vignanotica normal fault (Gargano, Southern Italy).

NASA Astrophysics Data System (ADS)

Maggi, Matteo; Cianfarra, Paola; Salvini, Francesco

2013-04-01

Faults have a (brittle) deformation zone that can be described as the presence of two distintive zones: an internal Fault core (FC) and an external Fault Damage Zone (FDZ). The FC is characterized by grinding processes that comminute the rock grains to a final grain-size distribution characterized by the prevalence of smaller grains over larger, represented by high fractal dimensions (up to 3.4). On the other hand, the FDZ is characterized by a network of fracture sets with characteristic attitudes (i.e. Riedel cleavages). This deformation pattern has important consequences on rock permeability. FC often represents hydraulic barriers, while FDZ, with its fracture connection, represents zones of higher permability. The observation of faults revealed that dimension and characteristics of FC and FDZ varies both in intensity and dimensions along them. One of the controlling factor in FC and FDZ development is the fault plane geometry. By changing its attitude, fault plane geometry locally alter the stress component produced by the fault kinematics and its combination with the bulk boundary conditions (regional stress field, fluid pressure, rocks rheology) is responsible for the development of zones of higher and lower fracture intensity with variable extension along the fault planes. Furthermore, the displacement along faults provides a cumulative deformation pattern that varies through time. The modeling of the fault evolution through time (4D modeling) is therefore required to fully describe the fracturing and therefore permeability. In this presentation we show a methodology developed to predict distribution of fracture intensity integrating seismic data and numerical modeling. Fault geometry is carefully reconstructed by interpolating stick lines from interpreted seismic sections converted to depth. The modeling is based on a mixed numerical/analytical method. Fault surface is discretized into cells with their geometric and rheological characteristics. For each

Do textbooks address known learning challenges in area measurement? A comparative analysis

NASA Astrophysics Data System (ADS)

Hong, Dae S.; Choi, Kyong Mi; Runnalls, Cristina; Hwang, Jihyun

2018-02-01

This study compared area lessons from Korean textbooks and US standard-based textbooks to understand differences and similarities among these textbooks, as well as how these textbooks address known learning challenges in area measurement. Several well-known challenges have been identified in previous studies, such as covering, array structure, and linking array structure to area formula. We were interested in knowing if textbooks addressed these issues in their treatments of area measurement and, in doing so, provided students with opportunities to overcome or become familiar with known challenges. The results show that both countries' textbooks demonstrated similar limitations; only few area and area-related lessons are covered and three important learning challenges in area measurement are not covered well, which need to be informed to practicing teachers.

Student Selection of the Textbook for an Introductory Physics Course

NASA Astrophysics Data System (ADS)

Dake, L. S.

2007-10-01

Several years ago I had to select a new textbook for my calculus-based introductory physics class. I subscribe to Just-in-Time Teaching methods, which require students to read the book before the material is covered in class. Thus, the readability of the text by the students is critical. However, I did not feel that I was the best judge of this factor, so I turned the textbook selection into a class project. The students unanimously chose one textbook, which I have now successfully used for three years. The project was decidedly worthwhile, and I gained considerable insight into what students prefer in a textbook.

Investigating the Conceptual Variation of Major Physics Textbooks

NASA Astrophysics Data System (ADS)

Stewart, John; Campbell, Richard; Clanton, Jessica

2008-04-01

The conceptual problem content of the electricity and magnetism chapters of seven major physics textbooks was investigated. The textbooks presented a total of 1600 conceptual electricity and magnetism problems. The solution to each problem was decomposed into its fundamental reasoning steps. These fundamental steps are, then, used to quantify the distribution of conceptual content among the set of topics common to the texts. The variation of the distribution of conceptual coverage within each text is studied. The variation between the major groupings of the textbooks (conceptual, algebra-based, and calculus-based) is also studied. A measure of the conceptual complexity of the problems in each text is presented.

Vicedo, Marga

2012-03-01

Starting in 1958, Harry Harlow published numerous research papers analyzing the emotional and social development of rhesus monkeys. This essay examines the presentation of Harlow's work in introductory psychology textbooks from 1958 to 1975, focusing on whether the textbooks erased the process of research, presented results without hedging, and provided a uniform account of Harlow's work and results. It argues that many textbooks were not passive vehicles of knowledge transmission; instead, they played a role similar to articles of meta-analysis and literature reviews.

[Palliative medicine content in German-language medical textbooks].

PubMed

Becker, G; Dausch, V; Xander, C; Olschewski, M; Momm, F; Blum, H E

2007-02-09

There is a need for improved end-of-life care, especially in the light of demographic changes with an increased incidence of cancer. Although medical textbooks are central to the training of medical students and also serve as a reference for more experienced clinicians, only few data exist on the extent to which medical textbooks address end-of-life care. We analysed the quantity and quality of information on end-of-life care given in German textbooks on different medical disciplines. 26 top-selling German medical textbooks were analysed for the presentation of end-of-life care in chapters that address the 13 most common causes of death worldwide In the 159 chapters analysed for information on traditional topics, like risk factors or early diagnosis (group A), such information was provided in 52% compared with only 9% on end-of-life topics, such as symptom management or manner of death (group B) (p=0.0001). There was no statistically significant difference between the different medical specialities (p=0.22). Line-by-line analysis showed that the phrase death or related terms was mentioned in only 57 of 159 chapters dealing with the most common causes of death worldwide. The top-selling German textbooks that were analysed generally offer little helpful information on end-of-life care of patients.

The Textbook of the Future: What Will It Look Like?

NASA Astrophysics Data System (ADS)

Shipman, Harry L.; Finkelstein, N.; McCray, D.; Mac Low, M.; Zollman, D.

2006-12-01

In May 2006, a group of scientists, publishers, technology gurus, National Science Foundation officers, and other interested parties met for a few days to think collectively about the future of the textbook. We met because: -The Web and search engines like Google change the relationship between students and information. If the textbook no longer needs to be encyclopedic, then what is its role? --Knowing information is not enough. Our students, whether they follow academic or other careers, will need to know how to get information, evaluate it, and use it to solve real world problems. How can a textbook help students in these environments? --The static, comprehensive narrative of a textbook does not always lend itself well to inquiry learning, which is strongly encouraged by science education research and by national science k-12 education standards. How can textbooks support active, student-centered learning and support new faculty as they adopt it? The workshop generated partial and uncertain answers to these questions, providing some ideas for the future, though not a complete roadmap. A metaphor that generated considerable support among the group was the idea of a textbook as a compact travel guide, like the Lonely Planet guides. It should be adaptable, and thus web-based, but it might still exist in paper form. The participants discussed barriers on the path ahead. How will peer review, which many workshop participants value, be incorporated? What incentives could motivate textbook authors and publishers to produce truly innovative products? How will new technologies such as computer simulations & animations, electronic readers, and widely accessible databases reshape the role of the textbook in education? Many workshop participants including this paper’s authors acknowledge support from the NSF Distinguished Teaching Scholars Program and the NSF CAREER awards program.

Perspectives on Violence Against Women: A Study of United States Nursing Textbooks.

PubMed

Price-Glynn, Kim; Missari, Stacy

2017-03-01

This study examines conceptualizations of violence against women in U.S. nursing textbooks published from 1995 to 2005. Framing this pivotal decade, the federal Violence Against Women Act (VAWA) was passed and renewed. The American Nurses Association, the National League for Nursing, and the American Association of Colleges of Nursing also recognized violence against women as a health care priority. Sampling 107 generalist nursing textbooks from 1995 to 2005, the current study analyzes textbook terminologies, arguments, and protocols. Textbooks including violence were empirically tested for their application of gender neutral, symmetrical, and asymmetrical theoretical frameworks. Over 40% of generalist textbooks did not mention violence against women. Despite the VAWA in 1994 and broad recognition across national nursing organizations, textbooks did not change with regard to their treatment of violence over the next decade. The frameworks that nursing textbooks use may foster challenges for nurses in recognizing, supporting, and assisting women who are victims/survivors of violence. [J Nurs Educ. 2017;56(3):164-169.].

Positioning genomics in biology education: content mapping of undergraduate biology textbooks.

PubMed

Wernick, Naomi L B; Ndung'u, Eric; Haughton, Dominique; Ledley, Fred D

2014-12-01

Biological thought increasingly recognizes the centrality of the genome in constituting and regulating processes ranging from cellular systems to ecology and evolution. In this paper, we ask whether genomics is similarly positioned as a core concept in the instructional sequence for undergraduate biology. Using quantitative methods, we analyzed the order in which core biological concepts were introduced in textbooks for first-year general and human biology. Statistical analysis was performed using self-organizing map algorithms and conventional methods to identify clusters of terms and their relative position in the books. General biology textbooks for both majors and nonmajors introduced genome-related content after text related to cell biology and biological chemistry, but before content describing higher-order biological processes. However, human biology textbooks most often introduced genomic content near the end of the books. These results suggest that genomics is not yet positioned as a core concept in commonly used textbooks for first-year biology and raises questions about whether such textbooks, or courses based on the outline of these textbooks, provide an appropriate foundation for understanding contemporary biological science.

How do the high school biology textbooks introduce the nature of science?

NASA Astrophysics Data System (ADS)

Lee, Young H.

2007-05-01

Although helping students to achieve an adequate understanding of the nature of science has been a consistent goal for science education for over half a century, current research reveals that the majority of students and teachers have naive views of the nature of science (Abd-El-khalick & Akerson, 2004; Bianchini & Colburn, 2000). This problem could be attributed not only to the complex nature of science, but also to the way the nature of science is presented to students during instruction. Thus, research must be conducted to examine how the science is taught, especially in science textbooks, which are a major instructional resource for teaching science. The aim of this study was to conduct a content analysis of the first chapter of four high school biology textbooks, which typically discusses "What is science?" and "What is biology?" This research used a content analysis technique to analyze the four high school biology textbooks, using a conceptual framework that has been used often for science textbook analysis. This conceptual framework consists of four themes of the nature of science: (a) science as a body of knowledge, (b) science as a way of thinking, (c) science as a way of investigating, and (d) the interaction of science, technology, and society. For this study, the four-theme-framework was modified to incorporate descriptors from national-level documents, such as Science for All Americans (AAAS, 1990) Benchmarks for Science Literacy (AAAS, 1993) and the National Science Education Standards (NRC, 1996), as well as science education research reports. A scoring procedure was used that resulted in good to excellent intercoder agreement with Cohen's kappa (k) ranging from .63 to .96. The findings show that the patterns of presentation of the four themes of the nature of science in the four high school biology textbooks are similar across the different locations of data, text, figures, and assessments. On the other hand, the pattern of presentation of the four

History of science content analysis of Chinese science textbooks from the perspective of acculturation

NASA Astrophysics Data System (ADS)

Ma, Yongjun; Wan, Yanlan

2017-08-01

Based on previous international studies, a content analysis scheme has been designed and used from the perspective of culture to study the history of science (HOS) in science textbooks. Nineteen sets of Chinese science textbooks have been analyzed. It has been found that there are noticeable changes in the quantity, content, layout, presentation, and writing intention of the HOS sections in textbooks from different time periods. What's more, the textbooks aim at presenting the scientific culture and aim to help students understand it better. However, the cultural associations of the HOS in textbooks is insufficient and significant differences exist among textbooks of different subjects. In order to explore the reasons why the presentation of HOS in various subjects is different, we made a specific comparison of curriculum standards of two subjects with great differences and interviewed the editors-in-chief of two textbooks. Results show that one of the most important reasons for the different writings of the HOS in textbooks is that different subject curriculum standards attach greater importance to the HOS. In addition, the attention to the HOS by editors-in-chief, the tradition of studying the HOS within the history of the discipline, and the reference textbooks in compiling textbooks are all important influence factors. Some suggestions for future textbooks compilation are given at the end.

Creationism in the Grand Canyon, Texas Textbooks

NASA Astrophysics Data System (ADS)

Folger, Peter

2004-01-01

AGU President Bob Dickinson, together with presidents of six other scientific societies, have written to Joseph Alston, Superintendent of Grand Canyon National Park, pointing out that a creationist book, The Grand Canyon: A Different View, is being sold in bookstores within the borders of the park as a scientific explanation about Grand Canyon geologic history. President Dickinson's 16 December letter urges that Alston clearly separate The Grand Canyon: A Different View from books and materials that discuss the legitimate scientific understanding of the origin of the Grand Canyon. The letter warns the Park Service against giving the impression that it approves of the anti-science movement known as young-Earth creationism, or that it endorses the advancement of religious tenets disguised as science. The text of the letter is on AGU's Web site http://www.agu.org/sci_soc/policy/sci_pol.html. Also, this fall, AGU sent an alert to Texas members about efforts by intelligent design creationists aimed at weakening the teaching of biological evolution in textbooks used in Texas schools. The alert pointed scientists to a letter, drafted by AGU, together with the American Institute of Physics, the American Physical Society, the Optical Society of America, and the American Astronomical Society, that urged the Texas State Board of Education to adopt textbooks that presented only accepted, peer-reviewed science and pedagogical expertise. Over 550 scientists in Texas added their names to the letter (http://www.agu.org/sci_soc/policy/texas_textbooks.pdf ), sent to the Board of Education on 1 November prior to their vote to adopt a slate of new science textbooks. The Board voted 11-5 in favor of keeping the textbooks free of changes advocated by groups supporting intelligent design creationism.

Comparative analysis of knowledge representation and reasoning requirements across a range of life sciences textbooks.

PubMed

Chaudhri, Vinay K; Elenius, Daniel; Goldenkranz, Andrew; Gong, Allison; Martone, Maryann E; Webb, William; Yorke-Smith, Neil

2014-01-01

Using knowledge representation for biomedical projects is now commonplace. In previous work, we represented the knowledge found in a college-level biology textbook in a fashion useful for answering questions. We showed that embedding the knowledge representation and question-answering abilities in an electronic textbook helped to engage student interest and improve learning. A natural question that arises from this success, and this paper's primary focus, is whether a similar approach is applicable across a range of life science textbooks. To answer that question, we considered four different textbooks, ranging from a below-introductory college biology text to an advanced, graduate-level neuroscience textbook. For these textbooks, we investigated the following questions: (1) To what extent is knowledge shared between the different textbooks? (2) To what extent can the same upper ontology be used to represent the knowledge found in different textbooks? (3) To what extent can the questions of interest for a range of textbooks be answered by using the same reasoning mechanisms? Our existing modeling and reasoning methods apply especially well both to a textbook that is comparable in level to the text studied in our previous work (i.e., an introductory-level text) and to a textbook at a lower level, suggesting potential for a high degree of portability. Even for the overlapping knowledge found across the textbooks, the level of detail covered in each textbook was different, which requires that the representations must be customized for each textbook. We also found that for advanced textbooks, representing models and scientific reasoning processes was particularly important. With some additional work, our representation methodology would be applicable to a range of textbooks. The requirements for knowledge representation are common across textbooks, suggesting that a shared semantic infrastructure for the life sciences is feasible. Because our representation overlaps

A gender analysis of secondary school physics textbooks and laboratory manuals

NASA Astrophysics Data System (ADS)

Kostas, Nancy Ann

Secondary school physics textbooks and laboratory manuals were evaluated for gender balance. The textbooks and manuals evaluated were all current editions available at the time of the study with copyrights of 1988 to 1992. Illustrations, drawings and photographs were judged gender balanced based on the number of men and women, boys and girls shown in both active and passive roles. Illustrations, drawings and photographs were also evaluated by the number of male and female scientists identified by name. The curricular content of the textbooks was analyzed for gender balance by three criteria: the number of named male and female scientists whose accomplishments were described in the text; the number of careers assigned to men and women; and the number of verbal analogies assigned to girls interests, boys interests or neutral interests. The laboratory activities in the manuals were categorized as demonstrations, experiments and observations. Three of each of these types of activities from each manual were analyzed for skills and motivating factors important to girls as identified by Potter and Rosser (1992). Data were analyzed by use of descriptive statistics of frequencies, means and chi-square goodness of fit. The.05 level of significance was applied to all analyses based upon an expected frequency of 50 - 50 percentage of men and women and a 4.5 percent for women scientists to 95.5 percent for men scientists. The findings were as follows. None of the textbooks had a balance of men/women, boys/girls in the illustrations, drawings and photographs. The Hewitt (Scott-Foresman, 1989) textbook was the only textbook with no significant difference. Using the expected frequency for male and female scientists, two textbooks were gender balanced for illustrations, drawings and photographs while all textbooks were gender balanced for described accomplishments of scientists. The Hewitt (Scott Foresman, 1989) textbook had the only gender balanced representation of careers

Brunet, Darlene P; Bates, Michael L; Gallo, John R; Strother, Elizabeth A

2011-05-01

Since 2005, the Louisiana State University Health Sciences Center School of Dentistry has required the VitalSource Technologies, Inc. Bookshelf as the textbook program for all dental students. In a 2008 survey, four classes of dental students expressed dissatisfaction with most features of the bookshelf. With the expectation that incoming students would be more accustomed and amenable to digital textbooks and to further determine student attitudes toward electronic textbooks, we developed two surveys for first-year dental students in the class of 2013. The sixty-five first-year students received a survey (S1) one week before they were introduced to the e-textbook program. Questions centered on their undergraduate experience with e-books and their expectations of studying with an electronic textbook collection. In the second survey (S2), sent nine months later, the questions focused on students' opinion of the VitalSource Bookshelf. Forty-five students (69.2 percent) completed the S1 survey. Of those, thirty-six (80 percent) responded that they never used e-textbooks in college. Of the nine students who responded that they used e-books, only two liked them without reservations. The response rate to S2 increased to fifty students (77 percent). After using VitalSource for nine months, thirty-three students (66 percent) indicated a preference for reading print textbooks, compared to forty-seven students (57.3 percent) of the four classes surveyed in 2008. Although we expected incoming dental students to have had previous experience with e-textbooks, only nine students had used e-books in college courses. Few students indicated preference for e-textbooks, and over half of the group was undecided. After experience with VitalSource for first-year courses, students indicated that they like VitalSource for the ability to search for specific topics across the entire collection of dental books, but not for reading large amounts of text.

Understanding European education landscape on natural disasters - a textbook research

NASA Astrophysics Data System (ADS)

Komac, B.; Zorn, M.; Ciglič, R.; Steinführer, A.

2012-04-01

The importance of natural-disaster education for social preparedness is presented. Increasing damage caused by natural disasters around the globe draws attention to the fact that even developed societies must adapt to natural processes. Natural-disaster education is a component part of any education strategy for a sustainably oriented society. The purpose of this article is to present the role of formal education in natural disasters in Europe. To ensure a uniform overview, the study used secondary-school geography textbooks from the collection at the Georg Eckert Institute for International Textbook Research in Braunschweig, Germany. Altogether, nearly 190 textbooks from 35 European countries were examined. The greatest focus on natural disasters can be found in textbooks published in western Europe (3.8% of pages describing natural disasters), and the smallest in those published in eastern Europe (0.7%). A share of textbook pages exceeding three percent describing natural disasters can also be found in northern Europe (3.6%) and southeast Europe, including Turkey (3.4%). The shares in central and southern Europe exceed two percent (i.e., 2.8% and 2.3%, respectively). The types and specific examples of natural disasters most commonly covered in textbooks as well as the type of natural disasters presented in textbooks according to the number of casualties and the damage caused were analyzed. The results show that the majority of European (secondary-school) education systems are poorly developed in terms of natural-disaster education. If education is perceived as part of natural-disaster management and governance, greater attention should clearly be dedicated to this activity. In addition to formal education, informal education also raises a series of questions connected with the importance of this type of education. Special attention was drawn to the importance of knowledge that locals have about their region because this aspect of education is important in both

Gong, Lunkun; Chen, Xiong; Musa, Omer; Yang, Haitao; Zhou, Changsheng

2017-12-01

Numerical and experimental investigation on the solid-fuel ramjet was carried out to study the effect of geometry on combustion characteristics. The two-dimensional axisymmetric program developed in the present study adopted finite rate chemistry and second-order moment turbulence-chemistry models, together with k-ω shear stress transport (SST) turbulence model. Experimental data were obtained by burning cylindrical polyethylene using a connected pipe facility. The simulation results show that a fuel-rich zone near the solid fuel surface and an air-rich zone in the core exist in the chamber, and the chemical reactions occur mainly in the interface of this two regions; The physical reasons for the effect of geometry on regression rate is the variation of turbulent viscosity due to the geometry change. Port-to-inlet diameter ratio is the main parameter influencing the turbulent viscosity, and a linear relationship between port-to-inlet diameter and regression rate were obtained. The air mass flow rate and air-fuel ratio are the main influencing factors on ramjet performances. Based on the simulation results, the correlations between geometry and air-fuel ratio were obtained, and the effect of geometry on ramjet performances was analyzed according to the correlation. Three-dimensional regression rate contour obtained experimentally indicates that the regression rate which shows axisymmetric distribution due to the symmetry structure increases sharply, followed by slow decrease in axial direction. The radiation heat transfer in recirculation zone cannot be ignored. Compared with the experimental results, the deviations of calculated average regression rate and characteristic velocity are about 5%. Concerning the effect of geometry on air-fuel ratio, the deviations between experimental and theoretical results are less than 10%.

Troth, D.L.; Verdouw, A.J.; Tomlinson, J.G.

1974-01-01

A program to analyze, select, and experimentally evaluate low emission combustors for aircraft gas turbine engines is conducted to demonstrate a final combustor concept having a 50 percent reduction in total mass emissions (carbon monoxide, unburnt hydrocarbons, oxides of nitrogen, and exhaust smoke) without an increase in any specific pollutant. Research conducted under an Army Contract established design concepts demonstrating significant reductions in CO and UHC emissions. Two of these concepts were an extended length intermediate zone to consume CO and UHC and variable geometry to control the primary zone fuel air ratio over varying power conditions. Emission reduction featuresmore » were identified by analytical methods employing both reaction kinetics and empirical correlations. Experimental results were obtained on a T63 component combustor rig operating at conditions simulating the engine over the complete power operating range with JP-4 fuel. A combustor incorporating both extended length and variable geometry was evaluated and the performance and emission results are reported. These results are compared on the basis of a helicopter duty cycle and the EPA 1979 turboprop regulation landing take off cycle. The 1979 EPA emission regulations for P2 class engines can be met with the extended length variable geometry combustor on the T63 turboprop engine.« less

Health effects of digital textbooks on school-age children: a grounded theory approach.

PubMed

Seomun, Gyeongae; Lee, Jung-Ah; Kim, Eun-Young; Im, Meeyoung; Kim, Miran; Park, Sun-A; Lee, Youngjin

2013-10-01

This qualitative study used the grounded theory approach to analyze digital textbook-related health experiences of school-age children. In-depth interviews were held with 40 elementary school students who had used digital textbooks for at least a year. Data analysis revealed a total of 56 concepts, 20 subcategories, and 11 categories related to digital textbook health issues, the central phenomena being "health-related experiences." Students' health-related experiences were classified into "physical" and "psychological" symptoms. Adverse health effects related to digital textbook usage were addressed via both "student-led" and "instructor-led" coping strategies. Students' coping strategies were often inefficient, but instructor-led strategies seemed to prevent health problems. When health issues were well managed, students tended to accept digital textbooks as educational tools. Our findings suggest that students can form healthy computer habits if digital textbook usage is directed in a positive manner.

Physics textbooks from the viewpoint of network structures

NASA Astrophysics Data System (ADS)

Králiková, Petra; Teleki, Aba

2017-01-01

We can observe self-organized networks all around us. These networks are, in general, scale invariant networks described by the Bianconi-Barabasi model. The self-organized networks (networks formed naturally when feedback acts on the system) show certain universality. These networks, in simplified models, have scale invariant distribution (Pareto distribution type I) and parameter α has value between 2 and 5. The textbooks are extremely important in the learning process and from this reason we studied physics textbook at the level of sentences and physics terms (bipartite network). The nodes represent physics terms, sentences, and pictures, tables, connected by links (by physics terms and transitional words and transitional phrases). We suppose that learning process are more robust and goes faster and easier if the physics textbook has a structure similar to structures of self-organized networks.

Bhutani, Garima; Kalra, Sanjay

2015-01-01

The study is aimed to assess whether the information contained in standard pharmacology, endocrinology, and diabetology textbooks regarding timings of administration, frequency and dose of various insulins is adequate and also to see whether the information contained in these texts is concordant with product inserts. Four standard textbooks of pharmacology, two of diabetology and three of endocrinology were assessed for the published information regarding dose, timing, and frequency of insulin administration. The product inserts of commonly available insulins in India were also studied for the same. Various omissions and disparities could be seen in the coverage of insulins in standard textbooks. Posology information about premixed insulins and basal insulins have been omitted by the majority of the textbooks. Details about dose, frequency and timings of ultra-short acting insulins have also not been covered by all textbooks. Some discrepancies regarding prescribing information was also noted in product inserts, especially in case of newer insulins. Thus, this article stresses upon the need of a uniform source of information for providing adequate and standardized knowledge regarding timing, frequency, and dose of insulins.

Medical Subspecialty Textbooks in the 21st Century. Essential or Headed for Extinction?

PubMed

Broaddus, V Courtney; Grippi, Michael A

2015-08-01

In recent years, the role of medical subspecialty textbooks as sources of information for students, trainees, and practicing clinicians has been challenged. Although the structure of textbooks continues to evolve from standard, printed versions to digital formats, including e-books and online texts, we maintain that the authoritative compilation of clinical and scientific material by experts in the field (i.e., a modern-day textbook) remains central to the education, training, and practice of subspecialists. Regardless of format, an effective medical subspecialty textbook is authoritative, comprehensive, and integrated in its coverage of the subject. Textbook content represents a unique synthesis of clinical and scientific material of real educational and clinical value. Incorporation of illustrations, including figures, tables, videos, and audios, bolsters the presentation and further solidifies the reader's understanding of the subject. The textbook, both printed and digital, reinforces the many widely available online resources and serves as a platform from which to evaluate other sources of information and to launch additional scientific and clinical inquiry.

End of life content in geriatric textbooks: what is the current situation?

PubMed Central

Wu, Huei Yaw; Malik, Farida A; Higginson, Irene J

2006-01-01

Background Physicians caring for elderly people encounter death and dying more frequently than their colleagues in most other disciplines. Therefore we sought to examine the end-of-life content in popular geriatric textbooks and determine their usefulness in helping geriatricians manage patients at the end of their lives. Methods Five popular geriatric textbooks were chosen. Chapters on Alzheimer's disease, stroke, chronic heart failure, chronic obstructive pulmonary disease and lung cancer were examined because of their high mortality rates among the elderly patients. Text relevant to end-of-life care was highlighted. Two reviewers independently coded text into 10 pre specified domains and rated them for the presence of end-of-life information. Content was rated as absent, minimally helpful, or helpful. The proportion of helpful information was calculated. Results The textbook with the best end-of-life coverage contained 38% helpful information, the worst had only 15% helpful information. Minimally helpful information ranged from 24% to 50%. As much as 61% of the content in one textbook contained no helpful information at all. Of the ten domains, epidemiology, disease progression and prognostic factors were fairly well covered. Information on advance care planning, ethical issues, decision making and effects of death and dying on patient's family were generally lacking under the individual diseases though they were covered as general topics in other parts of the textbooks. All except one textbook dedicated a chapter to the care of the dying. Conclusion This study showed that end-of-life content in geriatric textbooks differed significantly. Most of the textbooks lack good coverage on end-of-life care and more can be done to improve on this. PMID:16737524

The First American Textbook of Surgery

PubMed Central

Smythe, W. Roy

2003-01-01

The first systematic textbook of surgery written in the United States, The Elements of Surgery, was completed in 1813 by John Syng Dorsey, a University of Pennsylvania surgeon. The work thoroughly covered all major clinical areas of surgery of that time in a two-volume, 797-page text. Subsequent editions were published in 1818, 1823, and 1831. It became the standard surgical textbook in this country during that era and was the first American medical text exported abroad for use at the more established European centers of medical education. The reasons for writing the text included a desire to put into print the teachings of Philip Syng Physick (first Chair of the Department of Surgery at the University of Pennsylvania, and Dorsey’s uncle), the new American nationalism, and socioeconomic pressures forced on the American publishing industry by the War of 1812 and preceding trade embargoes. In addition to extensive exposure to Physick, Dorsey was also uniquely qualified to write and illustrate this text, as he exhibited an unusually succinct style and was a remarkable medical artist. The book was the forerunner to William Gibson’s The Institutes and Practice of Surgery and all American surgical textbooks to follow. PMID:12677156

Transfer zones in listric normal fault systems

NASA Astrophysics Data System (ADS)

Bose, Shamik

Listric normal faults are common in passive margin settings where sedimentary units are detached above weaker lithological units, such as evaporites or are driven by basal structural and stratigraphic discontinuities. The geometries and styles of faulting vary with the types of detachment and form landward and basinward dipping fault systems. Complex transfer zones therefore develop along the terminations of adjacent faults where deformation is accommodated by secondary faults, often below seismic resolution. The rollover geometry and secondary faults within the hanging wall of the major faults also vary with the styles of faulting and contribute to the complexity of the transfer zones. This study tries to understand the controlling factors for the formation of the different styles of listric normal faults and the different transfer zones formed within them, by using analog clay experimental models. Detailed analyses with respect to fault orientation, density and connectivity have been performed on the experiments in order to gather insights on the structural controls and the resulting geometries. A new high resolution 3D laser scanning technology has been introduced to scan the surfaces of the clay experiments for accurate measurements and 3D visualizations. Numerous examples from the Gulf of Mexico have been included to demonstrate and geometrically compare the observations in experiments and real structures. A salt cored convergent transfer zone from the South Timbalier Block 54, offshore Louisiana has been analyzed in detail to understand the evolutionary history of the region, which helps in deciphering the kinematic growth of similar structures in the Gulf of Mexico. The dissertation is divided into three chapters, written in a journal article format, that deal with three different aspects in understanding the listric normal fault systems and the transfer zones so formed. The first chapter involves clay experimental models to understand the fault patterns in

Misrepresentation, liberalism, and heterosexual bias in introductory psychology textbooks.

PubMed

McDonald, G

1981-01-01

The present study investigated the content of 48 introductory psychology textbooks published over a five-year period (1975-1979) and recommended by publishing companies or psychology professors for use in Canadian universities. The findings indicated that for every one source of relevant information on homosexuality there were five sources of misrepresentative data that reflect a combination of misleading information, liberalism, and heterosexual bias. Textbook editors and authors have: (1) failed to address the rights and needs of gay people; (2) failed to document accurately the social changes associated with being gay; and (3) perpetuated societal stereotypes, thereby appearing to justify the prejudice and discrimination encountered by gay people in their daily lives. Guidelines for the discussion of lesbianism and male homosexuality in introductory psychology textbooks are proposed.

Discussion of death and dying in surgical textbooks.

PubMed

Easson, A M; Crosby, J A; Librach, S L

2001-07-01

Quality end-of-life care is an increasing concern for the public and the medical profession. Surgical textbooks could serve as an important educational and reference resource to improve this care. Four general surgical textbooks were scored for helpful information on death and dying for eight surgical diseases. For each disease, nine content domains related to care of the dying patient were evaluated. Three texts included a chapter on cancer that was evaluated separately. Disease epidemiology, prognosis/prevention, progression, and medical interventions were generally well discussed in all textbooks. However, little helpful information was provided with regards to breaking bad news/advanced care planning, mode of death, treatment decision-making, effect on family/surgeon, and symptom management. Cancer chapters also addressed only a few of these concerns. Death and the dying patient are sufficiently frequent in surgical practice that it would be appropriate to increase the amount of information provided.

Geometry and kinematics of the fold-thrust belt and structural evolution of the major Himalayan fault zones in the Darjeeling -- Sikkim Himalaya, India

NASA Astrophysics Data System (ADS)

Bhattacharyya, Kathakali

The Darjeeling-Sikkim Himalaya lies in the eastern part of the Himalayan fold-thrust belt (FTB) in a zone of high arc-perpendicular convergence between the Indian and Eurasian plates. In this region two distinct faults form the Main Central thrust (MCT), the structurally higher MCT1 and the lower MCT2; both these faults have translated the Greater Himalayan hanging wall rocks farther towards the foreland than in the western Himalaya. The width of the sub-MCT Lesser Himalayan rocks progressively decreases from the western Himalaya to this part of the eastern Himalaya, and as a result, the width of the FTB is narrower in this region compared to the western Himalaya. Our structural analysis shows that in the Darjeeling-Sikkim Himalaya the sub-MCT Lesser Himalayan duplex is composed of two duplex systems and has a more complex geometry than in the rest of the Himalayan fold-thrust belt. The structurally higher Dating duplex is a hinterland-dipping duplex; the structurally lower Rangit duplex varies in geometry from a hinterland-dipping duplex in the north to an antiformal stack in the middle and a foreland-dipping duplex in the south. The MCT2 is the roof thrust of the Daling duplex and the Ramgarh thrust is the roof thrust of the Rangit duplex. In this region, the Ramgarh thrust has a complex structural history with continued reactivation during footwall imbrication. The foreland-dipping component of the Rangit duplex, along with the large displacement associated with the reactivation of the Ramgarh thrust accounts for the large translation of the MCT sheets in the Darjeeling-Sikkim Himalaya. The growth of the Lesser Himalayan duplex modified the final geometry of the overlying MCT sheets, resulting in a plunge culmination that manifests itself as a broad N-S trending "anticline" in the Darjeeling-Sikkim Himalaya. This is not a "river anticline" as its trace lies west of the Teesta river. A transport parallel balanced cross section across this region has accommodated

Effects of Oblique Extension and Inherited Structure Geometry on Transfer Zone Development in Continental Rifts: A 4D Analogue Modeling Approach

NASA Astrophysics Data System (ADS)

Zwaan, Frank; Schreurs, Guido

2015-04-01

INTRODUCTION Inherited structures in the crust form weak zones along which deformation will focus during rifting. Along-strike connection of rift segments may occur along transfer zones, as observed in East Africa. Previous studies have focused on numerical and analog modeling of transfer zones (e.g. Acocella et al., 1999, Allken et al., 2012). We elaborate upon those by investigating the effects of 1) oblique extension and 2) the geometry of linked and non-linked inherited structures on the development of transfer zones. A further improvement is the use of X-ray Computer Tomography (CT) for detailed internal analysis. METHODS The experimental set-up (see Schreurs & Colleta, 1998) contains two sidewalls with a base of compressed foam and plexiglass bars stacked in between. Decompressing this base results in distributed deformation of the overlying model materials. Deforming the model laterally with a mobile base plate produces the strike-slip components for oblique extension. Divergence velocities are in the order of 5 mm/h, translating to ca. 5 mm/Ma in nature, and 1 cm represents 10 km. A 2 cm thick layer of viscous silicone represents the ductile lower crust and a 2 cm quartz sand layer the brittle upper crust. Inherited structures are created with thin lines of silicon laid down on top of the basal silicone layer. Several models were run in a CT-scanner to reveal the 3D evolution of internal structures with time, hence 4D. RESULTS Localization of deformation along the pre-defined structures works well. The models show that the structural style changes with extension obliquity, from wide rift structures to narrower rifts with internal oblique-slip and finally strike-slip structures. Furthermore, rift offset is an important parameter influencing the occurrence of linkage: increasing rift offset decreases linkage as previously observed by Allken et al. (2012). However, increasing divergence obliquity promotes transfer zone formation, as does the presence of rift

Slab Geometry and Deformation in the Northern Nazca Subduction Zone Inferred From The Relocation and Focal mechanisms of Intermediate-Depth Earthquakes

NASA Astrophysics Data System (ADS)

Chang, Y.; Warren, L. M.; Prieto, G. A.

2015-12-01

In the northern Nazca subduction zone, the Nazca plate is subducting to the east beneath the South American Plate. At ~5.6ºN, the subducting plate has a 240-km east-west offset associated with a slab tear, called the Caldas tear, that separates the northern and southern segments. Our study seeks to better define the slab geometry and deformation in the southern segment, which has a high rate of intermediate-depth earthquakes (50-300 km) between 3.6ºN and 5.2ºN in the Cauca cluster. From Jan 2010 to Mar 2014, 228 intermediate-depth earthquakes in the Cauca cluster with local magnitude Ml 2.5-4.7 were recorded by 65 seismic stations of the Colombian National Seismic Network. We review and, if necessary, adjust the catalog P and S wave arrival picks. We use the travel times to relocate the earthquakes using a double difference relocation method. For earthquakes with Ml ≥3.8, we also use waveform modeling to compute moment tensors . The distribution of earthquake relocations shows an ~15-km-thick slab dipping to the SE. The dip angle increases from 20º at the northern edge of the cluster to 38º at the southern edge. Two concentrated groups of earthquakes extend ~40 km vertically above the general downdip trend, with a 20 km quiet gap between them at ~100 km depth. The earthquakes in the general downdip seismic zone have downdip compressional axes, while earthquakes close to the quiet gap and in the concentrated groups have an oblique component. The general decrease in slab dip angle to the north may be caused by mantle flow through the Caldas tear. The seismicity gap in the slab may be associated with an active deformation zone and the concentrated groups of earthquakes with oblique focal mechanisms could be due to a slab fold.

2014-09-01

Health education in schools is one of the most effective ways of promoting health in a society. Studies have shown the effectiveness of health interventions aimed at improving students' knowledge, attitude, and behaviors about health issues. The aim of this study was to evaluate health issues in primary school textbooks in Iran. In school year 2010-2011, the contents of all primary school textbooks in Iran were assessed in accordance to their health-related teachings. Health lessons of these 27 textbooks in the form of picture and text were retrieved and analyzed using content analysis method. In total, 502 health-related lessons were found. The textbooks of the third grade contained the highest (144) and those of the fourth grade had the lowest (26) number of health lessons. Among health-related issues, the largest number (87) of lessons were about personal hygiene, while prevention of high risk behaviors comprised the least number (8). Some important health issues such as nutrition, oral health, and prevention of high-risk behaviors were not adequately discussed in the textbooks. The potential of primary school textbooks in delivering health messages has been neglected in Iran. Taking the critical importance of school ages into account, incorporating health issues in textbooks should be more strongly emphasized.

A visual analysis of gender bias in contemporary anatomy textbooks.

PubMed

Parker, Rhiannon; Larkin, Theresa; Cockburn, Jon

2017-05-01

Empirical research has linked gender bias in medical education with negative attitudes and behaviors in healthcare providers. Yet it has been more than 20 years since research has considered the degree to which women and men are equally represented in anatomy textbooks. Furthermore, previous research has not explored beyond quantity of representation to also examine visual gender stereotypes and, in light of theoretical advancements in the area of intersectional research, the relationship between representations of gender and representations of ethnicity, body type, health, and age. This study aimed to determine the existence and representation of gender bias in the major anatomy textbooks used at Australian Medical Schools. A systematic visual content analysis was conducted on 6044 images in which sex/gender could be identified, sourced from 17 major anatomy textbooks published from 2008 to 2013. Further content analysis was performed on the 521 narrative images, which represent an unfolding story, found within the same textbooks. Results indicate that the representation of gender in images from anatomy textbooks remain predominantly male except within sex-specific sections. Further, other forms of bias were found to exist in: the visualization of stereotypical gendered emotions, roles and settings; the lack of ethnic, age, and body type diversity; and in the almost complete adherence to a sex/gender binary. Despite increased attention to gender issues in medicine, the visual representation of gender in medical curricula continues to be biased. The biased construction of gender in anatomy textbooks designed for medical education provides future healthcare providers with inadequate and unrealistic information about patients.

First-year engineering students' use of their mathematics textbook - opportunities and constraints

NASA Astrophysics Data System (ADS)

Randahl, Mira

2012-09-01

The role of the mathematics textbook at tertiary level has received limited exposure in previous research although it is likely that students work individually and that some of this work depends on the use of the textbook. The aim of this study was to investigate the process of approaching the textbook from epistemological, cognitive, and didactical perspectives. The focus was on identifying and discussing the opportunities and constraints in the process. The study was an explorative case study and the participants were first-year engineering students taking a basic calculus course. The data were collected through questionnaires, observations, and interviews. Results showed that the textbook was used to a very low degree and mainly perceived as a source of tasks. Different opportunities and constraints are pointed out and some didactical implications are suggested. The results and discussion indicate that a need for greater awareness about the use of mathematical textbooks in meaningful ways at tertiary level.

Revisiting the physical characterisitics of the subduction interplate seismogenic zones

NASA Astrophysics Data System (ADS)

Heuret, Arnauld; Lallemand, Serge; Funiciello, Francesca; Piromallo, Claudia

2010-05-01

Based on the Centennial earthquake catalog, the revised 1964-2007 EHB hypocenters catalog and the 1976-2007 CMT Harvard catalog, we have extracted the hypocenters, nodal planes and seismic moments of worldwide subduction earthquakes for the 1900-2007 period. For the 1976-2007 period, we combine the focal solutions provided by Harvard and the revised hypocenters from Engdahl et al. (1998). Older events are extracted from the Centennial catalogue (Engdahl and Villasenor, 2002) and they are used to estimate the cumulated seismic moment only. The selection criteria for the subduction earthquakes are similar to those used by Mc Caffrey (1994), i.e., we test if the focal mechanisms are consistent with 1/ shallow thrust events (depth > 70 km, positive slips, and at least one nodal plane gets dip < 45°), and, 2/ the plate interface local geometry and orientation (one nodal plane is oriented toward the volcanic arc, the azimuth of this nodal plane ranges between ± 45° with respect to the trench one, its dip ranges between ± 20° with respect to the slab one and the epicentre is located seaward of the volcanic arc). Our study concerns segments of subduction zones that fit with estimated paleoruptures associated with major events (M > 8). We assume that the seismogenic zone coincides with the distribution of 5.5 < M < 7 subduction earthquakes. We provide a map of the interplate seismogenic zones for 80% of the trench systems including dip, length, downdip and updip limits, we revisit the statistical study done by Pacheco et al. (1993) and test some empirical laws obtained for example by Ruff and Kanamori (1980) in light of a more complete, detailed, accurate and uniform description of the subduction interplate seismogenic zone. Since subduction earthquakes result from stress accumulation along the interplate and stress depends on plates kinematics, subduction zone geometry, thermal state and seismic coupling, we aim to isolate some correlations between parameters.

By applied this textbook, students would be helped to get a deeper conceptual understanding and better characters.

Geometry and Material Constraint Effects on Creep Crack Growth Behavior in Welded Joints

NASA Astrophysics Data System (ADS)

Li, Y.; Wang, G. Z.; Xuan, F. Z.; Tu, S. T.

2017-02-01

In this work, the geometry and material constraint effects on creep crack growth (CCG) and behavior in welded joints were investigated. The CCG paths and rates of two kinds of specimen geometry (C(T) and M(T)) with initial cracks located at soft HAZ (heat-affected zone with lower creep strength) and different material mismatches were simulated. The effect of constraint on creep crack initiation (CCI) time was discussed. The results show that there exists interaction between geometry and material constraints in terms of their effects on CCG rate and CCI time of welded joints. Under the condition of low geometry constraint, the effect of material constraint on CCG rate and CCI time becomes more obvious. Higher material constraint can promote CCG due to the formation of higher stress triaxiality around crack tip. Higher geometry constraint can increase CCG rate and reduce CCI time of welded joints. Both geometry and material constraints should be considered in creep life assessment and design for high-temperature welded components.

1997-01-01

The technique and rationale for the use of nursing diagnosis generally are introduced early in the undergraduate curriculum. The three purposes of this descriptive study were to describe the general characteristics and presentation of content on nursing diagnosis in fundamentals of nursing textbooks; describe how the content from the theoretical chapter(s) in nursing diagnosis is carried through in the clinical chapters; and describe how content on diagnostic errors is presented. Although most of the textbooks presented content on nursing diagnosis in a similar fashion, the clinical chapters of the books did not follow the same pattern. Content on diagnostic errors was inconsistent. Educators may find this an effective methodology for reviewing textbooks.

Adams, Mark F.; Samtaney, Ravi, E-mail: samtaney@pppl.go; Brandt, Achi

Multigrid methods can solve some classes of elliptic and parabolic equations to accuracy below the truncation error with a work-cost equivalent to a few residual calculations - so-called 'textbook' multigrid efficiency. We investigate methods to solve the system of equations that arise in time dependent magnetohydrodynamics (MHD) simulations with textbook multigrid efficiency. We apply multigrid techniques such as geometric interpolation, full approximate storage, Gauss-Seidel smoothers, and defect correction for fully implicit, nonlinear, second-order finite volume discretizations of MHD. We apply these methods to a standard resistive MHD benchmark problem, the GEM reconnection problem, and add a strong magnetic guide field,more » which is a critical characteristic of magnetically confined fusion plasmas. We show that our multigrid methods can achieve near textbook efficiency on fully implicit resistive MHD simulations.« less

Textbook images: how do they invite students into physics?

NASA Astrophysics Data System (ADS)

Bungum, Berit

2013-09-01

This paper presents a study of images in Norwegian physics textbooks for upper secondary school, and how they invite students into physics by means of visual communication. The concept of ‘framing’ is used to investigate how the perspective in the image provides a sense of participation. It is found that older textbooks, where objects and experimental setups dominate the images, involve the reader in terms of weak framing. This is to some degree resembled in newer textbooks with the increased use of photographs of learners in some physics activity. This does, however, invite the learner into school physics rather than professional physics. Connections made to physics in society and everyday life in images can also be seen as inviting the learner into physics, by exhibiting how modern physicists work and by referring to the relevance of physics, respectively.

[Investigation of the publishing and using status of college genetics textbooks in China].

PubMed

Chen, Xiwen; Chen, Defu

2014-04-01

Using Wenjin Search of the National Library of China, it was found that 895 genetics textbooks for Chinese colleges, including 588 (67.5%) theoretical books, 122 (13.6%) experimental books and 185 (20.7%) teaching reference books, have been published since College Entrance Examination resumed. Most of these books belong to medical genetics, followed by general genetics, while the books on plant genetics, animal genetics or microbial genetics are relatively few. In these search results, 91 had the same name of Medical Genetics, professor Ji Zuo is the most productive author, who edited 9 genetics textbooks, and Science Press Ltd. is the most productive press, which published 179 (20%) genetics textbooks. The questionnaire survey showed that "Genetics" (Second Edition) edited by Zhuohua Dai is the most widely used textbooks in the Chinese colleges, while the mainly used experimental books are the handouts or self-edited textbooks. Finally, we analyzed the problems currently existed in the textbooks, such as slowly updating cycle, less supports, lots of books with the same name, lack of scientific stories, very rare and unique illustrations, too full printed pages, and also provided the proposed solution.

A free electronic astronomy textbook and OER hub

NASA Astrophysics Data System (ADS)

Fraknoi, Andrew

2017-11-01

How many of us who teach introductory astronomy in college or high school have thrown up our hands in despair over the cost of textbooks and worried about the fact that up-to-date editions were beyond the means of many of our students? I know I have had this worry, even though I have been a textbook author myself since the 1990s. I've had students unable to get the book, or groups of students sharing a book because they could not individually afford the price.

Modeling CANDU-6 liquid zone controllers for effects of thorium-based fuels

DOE Office of Scientific and Technical Information (OSTI.GOV)

St-Aubin, E.; Marleau, G.

2012-07-01

We use the DRAGON code to model the CANDU-6 liquid zone controllers and evaluate the effects of thorium-based fuels on their incremental cross sections and reactivity worth. We optimize both the numerical quadrature and spatial discretization for 2D cell models in order to provide accurate fuel properties for 3D liquid zone controller supercell models. We propose a low computer cost parameterized pseudo-exact 3D cluster geometries modeling approach that avoids tracking issues on small external surfaces. This methodology provides consistent incremental cross sections and reactivity worths when the thickness of the buffer region is reduced. When compared with an approximate annularmore » geometry representation of the fuel and coolant region, we observe that the cluster description of fuel bundles in the supercell models does not increase considerably the precision of the results while increasing substantially the CPU time. In addition, this comparison shows that it is imperative to finely describe the liquid zone controller geometry since it has a strong impact of the incremental cross sections. This paper also shows that liquid zone controller reactivity worth is greatly decreased in presence of thorium-based fuels compared to the reference natural uranium fuel, since the fission and the fast to thermal scattering incremental cross sections are higher for the new fuels.
