Mediastinal malignant lymphoma.

Ninety-seven cases of malignant lymphoma, clinically presenting in the mediastinum, were diagnosed by examination of surgical pathologic specimens. These specimens were analyzed in the light of newer concepts regarding lymphoma, including current classification and clinical staging of these tumors. The influences of clinical and histopathologic features and therapeutic modalities were assessed in regard to prognosis. Fifty-seven patients had Hodgkin's disease and 61.3 percent of these patients survived five years, whereas 40 patients had lymphosarcomas and only 15 percent of these patients survived five years. Generally, mature lymphocytic predominance of lymphomas and nodularity, particularly in lymphosarcoma, were histopathologic features that were associated with increased survival. Nodular sclerosis was noted in 35 of the patients and mixed cellularity in 19, and these patients had favorable survival rates. Thirteen of the 15 patients with lymphoma of stage I survived five years. Five of the six patients with thymic Hodgkin's disease treated by surgical excision and roentgen therapy survived five years or more. Radical surgery has a distinct place in the therapy of selected patients with mediastinal lymphoma.
Cacophony or Embarrassment of Riches Building a System of Support for Quality Teaching

Probability density of the power spectrum transfer function for a two-path and three-path factory radio channel

Channel parameters are obtained from a recent channel model which was developed from experimental factory data. The model shows that the average number of signals with relatively large amplitudes (not less than 10% of the largest signal present in the data) is three or less. Since most channel degradations result from large amplitude signals which cause severe fading, it is reasonable to find the fading statistics for channels with a few paths. In particular, the distribution of the power spectrum of the transfer function derived here can be used to design a reliable multiple-access communication system operating over such a multipath fading channel. >
Injury outcomes in children following automobile, motorcycle, and all-terrain vehicle accidents: an institutional review.

OBJECT: The authors performed an analysis of retrospectively obtained data to compare the outcomes of pediatric patients admitted to their institution for traumatic injuries resulting from car, motorcycle, and all-terrain vehicle (ATV) accidents. METHODS: The authors conducted a retrospective review of Columbus Children's Hospital's Trauma Registry data collected between January 1993 and December 2003. Data obtained in patients admitted with motor vehicle-related injuries were compiled for a total of 1608 patient records. Data regarding sex, age, hospital length of stay (LOS), Glasgow Coma Scale (GCS) score, revised trauma score, injury severity score (ISS), and use of a protective device were analyzed. CONCLUSIONS: Of 1608 patients, 1257 (78%) were injured in automobile accidents, 123 (7.6%) in motorcycle accidents, and 228 (14.2%) in ATV accidents. Injuries sustained in all vehicle types peaked during the summer months. Patients involved in automobile crashes presented with significantly lower GCS scores than those injured in motorcycle and ATV accidents; however, there was no statistically significant difference in LOS among all three injury modalities. Protective devices were underutilized in all three motor vehicle categories but, when used, were associated with significantly higher GCS scores, ISSs, and shorter LOSs among patients admitted after automobile accidents. The correlation of seat belt use with better outcomes underscores the necessity to improve motor vehicle safety education for children, who are less likely to be restrained as they age. Language: en

Rate constants at 298 k for the reactions SO+SO+M→(SO)2+M AND SO+(SO)2→SO2+S2O

Abstract The decay of SO generated in the reaction O+OCS → CO+SO in the absence of O2 has been studied at 298 K from 2 to 8 Torr, using a tubular flow reactor coupled to a mass spectrometer. The products of the decay of SO are S SO2, S2O. and (SO)2. The kinetics of the decay of SO could be accounted for on the basis of the mechanism SO+SO+M→ (SO)2+M (3), SO+SO→ SO2 + S (4). SO+(SO)2→SO2+S2O (5) and SO→ products (6). where the latter represents either a wall reaction or a slow bimolecular reaction with OCS. On the basis of computer modeling we derive k3 = 1.6 × 1017 cm6 mol−2s−1 and k5 = 2 × 1010cm3 mol−1 s−1
Detailed balance analysis of nanophotonic solar cells.

We present a detailed balance based approach for performing current density-voltage characteristic modeling of nanophotonic solar cells. This approach takes into account the intrinsic material non-idealities, and is useful for determining the theoretical limit of solar cell efficiency for a given structure. Our approach only requires the cell’s absorption spectra over all angles, which can be readily calculated using available simulation tools. Using this approach, we elucidate the physics of open-circuit voltage enhancement over bulk cells in nanoscale thin film structures, by showing that the enhancement is related to the absorption suppression in the immediate spectral region above the bandgap. We also show that with proper design, the use of a grating on a nanoscale thin film can increase its short-circuit current, while preserving its voltage-enhancing capabilities.
The Practical Aspects of Diagnosing and Managing Children with Attention Deficit Hyperactivity Disorder

AD/HD is a behaviorally defined disorder with specific behavioral criteria. The most recent definitions decrease heterogeneity by defining subtypes although the current treatments tend to be more generic. The main well-established treatments are stimulant medication and behavior modification, which are most effective when used together.
Heterogeneous distribution of antigens on human platelets demonstrated by fluorescence flow cytometry

We have used fluorescence flow cytometry to analyse cell-to-cell variability in the density of platelet ABH, Ii, Lewis, P, P1A1, Bak,a and HLA class I antigens. Human IgG and IgM antibodies were used in a two-stage assay with goat FITC-conjugated antihuman IgG (H&L) antibody as the label, followed by single cell analysis of 10 000 platelets per sample using a 256-channel fluorescence flow cytometer (Becton-Dickinson FACS Analyser). Computer analysis of fluorescence intensity histograms for mean and peak channel and coefficient of variation shows that the degree of heterogeneity in platelet antigen density varies with each particular blood group. The broad fluorescence distribution curves with oligosaccharide antigens (CVs: A = 53, B = 40, I = 44, Lea = 40, P = 40) indicate that these antigens possess a greater variability in the number of sites per cell compared to the more homogeneous distribution of P1,A1 BaK,a and HLA (CVs: P1A1 = 24, HLA = 30). These findings may partly account for the mechanism by which transfusion of ABO-incompatible platelets results in a biphasic survival curve, with a period of early rapid removal of those platelets with a high density of antigen sites, followed by a relatively normal survival curve for those platelets that possess only a few or no antigen sites. In contrast, P1A1 and HLA sites are less variable in number from one platelet to another in a given donor, and immune-mediated removal would be more likely to approximate a single exponential curve.
Understanding the information needs of public health practitioners: A literature review to inform design of an interactive digital knowledge management system

The need for rapid access to information to support critical decisions in public health cannot be disputed; however, development of such systems requires an understanding of the actual information needs of public health professionals. This paper reports the results of a literature review focused on the information needs of public health professionals. The authors reviewed the public health literature to answer the following questions: (1) What are the information needs of public health professionals? (2) In what ways are those needs being met? (3) What are the barriers to meeting those needs? (4) What is the role of the Internet in meeting information needs? The review was undertaken in order to develop system requirements to inform the design and development of an interactive digital knowledge management system. The goal of the system is to support the collection, management, and retrieval of public health documents, data, learning objects, and tools. Method:: The search method extended beyond traditional information resources, such as bibliographic databases, tables of contents (TOC), and bibliographies, to include information resources public health practitioners routinely use or have need to use-for example, grey literature, government reports, Internet-based publications, and meeting abstracts. Results:: Although few formal studies of information needs and information-seeking behaviors of public health professionals have been reported, the literature consistently indicated a critical need for comprehensive, coordinated, and accessible information to meet the needs of the public health workforce. Major barriers to information access include time, resource reliability, trustworthiness/credibility of information, and ''information overload''. Conclusions:: Utilizing a novel search method that included the diversity of information resources public health practitioners use, has produced a richer and more useful picture of the information needs of the public health workforce than other literature reviews. There is a critical need for public health digital knowledge management systems designed to reflect the diversity of public health activities, to enable human communications, and to provide multiple access points to critical information resources. Public health librarians and other information specialists can serve a significant role in helping public health professionals meet their information needs through the development of evidence-based decision support systems, human-mediated expert searching and training in the use information retrieval systems.
On the Development and Measurement of Spatial Ability.

The importance of spatial ability in learning different school subjects and being successful at certain jobs has been recognized globally. The vast majority of the studies on the topic have focused on the nature of the phenomenon, the factors that affect its development), and the difference between males and females on spatial ability. However, still there is a need to conduct research studies to have a better understanding of the construct, its relations with other abilities, and the ways to foster its development. By providing a literature review, this study addresses those issues and summarizes different ways of measuring spatial ability and fostering its development to suggest study directions to future researchers.
VoLTE*: A Lightweight Voice Solution to 4G LTE Networks

VoLTE is the designated voice solution to the LTE network. Its early deployment is ongoing worldwide. In this work, we report an assessment on VoLTE.We show that VoLTE offers no categorically better quality than popular VoIP applications in all tested scenarios except some congested scenarios. Given the high cost on infrastructure upgrade, we argue that VoLTE, in its current form, might not warrant the deployment effort. We sketch VOLTE*, a lightweight voice solution from which all parties of users, LTE carriers, and VoIP service providers may benefit.
Training Opportunities in Medical and Surgical Education

As a surgeon, the requirement for academic clinical practice is completion of an accredited residency program with or without a fellowship, followed by appropriate board certification. It was classically assumed that those who complete this rigorous training process in an academic setting naturally developed the teaching skills necessary to teach the next generation of academic surgeons. To date, no specific training paradigm has been defined for individuals desiring to become surgical educators. Historically, volunteer academic faculty have shouldered the responsibility of teaching medical students and residents with little to no additional insights beyond what they were exposed to during their own curriculum. Unfortunately, their teaching commitments were sometimes viewed as a distraction from the tasks of grant application and publication of research efforts. With the added pressures of research and clinical productivity, the ability and the time dedicated to teaching have been placed low on the prioritization of academic tasks. The “student” generational gap has changed since most of us have trained, as educational technology and techniques have evolved to capture the attention of our trainees.
Extension of the AMBER molecular dynamics software to Intel’s Many Integrated Core (MIC) architecture

Abstract We present an implementation of explicit solvent particle mesh Ewald (PME) classical molecular dynamics (MD) within the PMEMD molecular dynamics engine, that forms part of the AMBER v14 MD software package, that makes use of Intel Xeon Phi coprocessors by offloading portions of the PME direct summation and neighbor list build to the coprocessor . We refer to this implementation as pmemd MIC offload and in this paper present the technical details of the algorithm, including basic models for MPI and OpenMP configuration, and analyze the resultant performance. The algorithm provides the best performance improvement for large systems ( > 400,000 atoms), achieving a ∼35% performance improvement for satellite tobacco mosaic virus (1,067,095 atoms) when 2 Intel E5-2697 v2 processors (2 ×12 cores, 30M cache, 2.7 GHz) are coupled to an Intel Xeon Phi coprocessor (Model 7120P—1.238/1.333 GHz, 61 cores). The implementation utilizes a two-fold decomposition strategy: spatial decomposition using an MPI library and thread-based decomposition using OpenMP. We also present compiler optimization settings that improve the performance on Intel Xeon processors , while retaining simulation accuracy.
Machiavelli's Paradox: Trapping or Teaching the Prince

In The Discourses Machiavelli extolled the virtues of republican government, yet in The Prince he advised the ruler on how to perpetuate autocratic rule. What accounts for this paradox? Mary Dietz argues that Machiavelli sought to deceive the prince, trapping him into actions that would destroy his rule. John Langton contends, in contrast, that Machiavelli was seeking to teach the prince how to govern so that the autocratic state could evolve into a republic.

Neighborhood context, psychological outlook, and risk behaviors among urban African American youth.

Objectives Researchers have found a link between neighborhood risk factors and youth risk behaviors. However, the pathways by which this occurs remain poorly understood. This study sought to test a hypothesized pathway that suggests the influence of neighborhood risk on sexual risk and substance use among urban African American youth may operate indirectly via their psychological outlook about current and future opportunities. Method Secondary data analysis using structural equation modeling (SEM) was used to test the conceptual framework. The sample included 592 African American youth (61% female, 39% male) mean age 15.58 years, 1.23 SD. A modified structural equation model (SEM) met prespecified global fit index criteria. Results The model contained 3 indirect paths linking increased neighborhood risk to increased sexual risk and substance use through higher levels of negative psychological outlook and youth approval of substance use. Conclusions These findings increase our understanding of factors that influence the initiation and progression of substance use and sexual risk behaviors among urban African American adolescents.

Ethics and the Challenge of Theological Non-Realism

Theological non-realism presents a fundamental challenge to objective theism. Its attraction comes from the fact that the move to non-realism is justified by appealing to ethics. And coming from within the theological circle, in important respects this new challenge supplants even the longstanding challenge of atheism.
Proteomic modulation in breast tumors after metformin exposure: results from a “window of opportunity” trial

Reverse Phase Protein Array (RPPA) is a high-throughput antibody-based technique to assess cellular protein activity. The goal of this study was to assess protein marker changes by RPPA in tumor tissue from a pre-surgical metformin trial in women with operable breast cancer (BC). In an open-label trial, metformin 1500-mg PO daily was administered prior to resection in 35 non-diabetic patients with stage 0–III BC, body mass index ≥25 kg/m2. For RPPA, formalin-fixed paraffin-embedded (FFPE) samples were probed with 160 antibodies. Paired and two-sample t-tests were performed (p ≤ 0.05). Multiple comparisons were adjusted for by fixing the false discovery rate at 25 %. We evaluated whether pre- and post-metformin changes of select markers by RPPA were identified by immunohistochemistry (IHC) in these samples. We also assessed for these changes by western blot in metformin-treated BC cell lines. After adjusting for multiple comparisons in the 32 tumors from metformin-treated patients vs. 34 untreated historical controls, 11 proteins were significantly different between cases vs. controls: increases in Raptor, C-Raf, Cyclin B1, Cyclin D1, TRFC, and Syk; and reductions in pMAPKpT202,Y204, JNKpT183,pT185, BadpS112, PKC.alphapS657, and SrcpY416. Cyclin D1 change after metformin by IHC was not observed. In cell lines, reductions in JNKpT183 and BadpS112 were seen, with no change in Cyclin D1 or Raptor. These results suggest that metformin modulates apoptosis/cell cycle, cell signaling, and invasion/motility. These findings should be assessed in larger metformin trials. If confirmed, associations between these changes and BC clinical outcome should be evaluated. NCT00930579.
Reducing Complications and Margin Issues with Nipple-Sparing Mastectomy

Nipple-sparing mastectomy (NSM) followed by immediate reconstruction is associated with low morbidity and mortality rates. The most concerning complication is skin and nipple necrosis which can lead to patient dissatisfaction and ultimately loss of reconstruction. Patient selection plays a key role in minimizing complications. This chapter describes the most common complications associated with NSM and patient as well as technical factors that may be predictive of these complications. The various techniques for minimizing and managing nipple or flap necrosis are discussed. In addition, positive margin status after NSM presents concerns regarding need for reoperation with possible removal of the NAC as well as risk for local recurrence. This chapter will address incidence of close or positive margins following NSM, techniques to accurately assess retro-areolar margin status, management of positive margins, the potential role of post-mastectomy radiation in patients with close or positive margins and rates of local recurrence following NSM.

Sulfur Vapor-Infiltrated 3D Carbon Nanotube Foam for Binder-Free High Areal Capacity Lithium–Sulfur Battery Composite Cathodes

Here, we demonstrate a strategy to produce high areal loading and areal capacity sulfur cathodes by using vapor-phase infiltration of low-density carbon nanotube (CNT) foams preformed by solution processing and freeze-drying. Vapor-phase capillary infiltration of sulfur into preformed and binder-free low-density CNT foams leads to a mass loading of ∼79 wt % arising from interior filling and coating of CNTs with sulfur while preserving conductive CNT–CNT junctions that sustain electrical accessibility through the thick foam. Sulfur cathodes are then produced by mechanically compressing these foams into dense composites (ρ > 0.2 g/cm3), revealing specific capacity of 1039 mAh/gS at 0.1 C, high sulfur areal loading of 19.1 mg/cm2, and high areal capacity of 19.3 mAh/cm2. This work highlights a technique broadly adaptable to a diverse group of nanostructured building blocks where preformed low-density materials can be vapor infiltrated with sulfur, mechanically compressed, and exhibit simultaneous high areal ...
The impact of subchondral bone cysts on local bone stresses in the medial femoral condyle of the equine stifle joint

Subchondral lucency (SCL), also referred to as subchondral bone cysts, can cause clinical problems in horses and humans. In humans, SCLs occur in youths and adolescents [1] due to mechanical factors (often related to athletics) and in skeletally mature individuals secondary to osteoarthritis (OA). In horses, SCL most commonly occurs in the medial femoral condyle (MFC) of growing horses (without OA), and causes lameness. The cause of equine SCL is debated, but bone trauma due to overload is the likely mechanism. Investigating the biomechanics of the healthy and cystic MFC is important to understand cyst growth and to provide a foundation for new treatment strategies. We hypothesize that SCL alters the mechanical environment of surrounding bone, which in the presence of continued loading, may lead to enlargement of the SCL. In this study, we developed and validated a finite element model of an equine stifle joint and investigated the stresses associated with varying sizes of SCL. We found substantial differences in tensile and shear stress at various stages of SCL development that suggest further bone damage leading to SCL enlargement. These data provide a first step in understanding of the altered mechanics of subchondral bone surrounding a SCL. Additional studies may provide the basis for improved treatment strategies for SCL in young horses, and may improve the understanding of SCL in humans.
Chiefs, Constitutions, and Politics in Nigeria

As reflected in the four preceding quotations, the role and relevance of traditional political institutions in general, and traditional rulership in particular, continue to generate intense, and sometimes, quite acrimonious debates in Nigeria. Heated, bitter and rancorous debates on whether those who preside over indigenous political institutions who are variously designated numerous nomenclature as chiefs, emirs, obas, obis, olus, attahs, aiotse, and so on, should have any formal role in the political affairs of Nigeria elicit a great deal of interest and response both in scholarly writings and on the pages of newspapers and news-magazines. The term, traditional rulers, will be used in this paper to refer to the various political leaders who exercise political power at ethnic or sub-ethnic levels in Nigeria. While the term hints at the common fact these rulers operate outside the formal structures of modern state power in Nigeria, it underestimates the wide disparity in the locus and extent of powers exercised by this class of Nigerian leaders. For example, the Emir of Kano and the Tor Tiv fall into the same classification as traditional rulers. Yet, the Emir of Kano, both in the context of ethnic politics and within the larger purview of Nigerian politics is considerably more influential than the Tor Tiv.
Acyclic Quaternary Carbon Stereocenters via Enantioselective Transition Metal Catalysis

Whereas numerous asymmetric methods for formation of quaternary carbon stereocenters in cyclic systems have been documented, the construction of acyclic quaternary carbon stereocenters with control of absolute stereochemistry remains a formidable challenge. This Review summarizes enantioselective methods for the construction of acyclic quaternary carbon stereocenters from achiral or chiral racemic reactants via transition metal catalysis.
I-O Psychology and Technology: Why Reinvent the Wheel?

Morelli, Potosky, Arthur, and Tippins (2017) make a timely and appropriate call for authors to create conceptual models of technology in industrial-organizational (I-O) psychology. We agree with their call, but we believe that Morelli et al. overlooked the contributions of related fields that conduct research on technology in the workplace that are already consistent with their call. For this reason, we briefly detail other fields that commonly study the dynamics of technology and its influence on the workplace, followed by a discussion regarding the place of I-O psychology in the broader scheme of technology research. This discussion can aid future authors in conceptualizing appropriate contributions to the study of technology in I-O psychology as well as identifying whether these contributions benefit other fields. Perhaps more importantly, this discussion can help identify where I-O psychology fits in the broader scheme of technology research and which associated fields may be most readily available to aid in the creation of new models—two questions that currently seem unanswered.
Experiences and perceptions of online continuing professional development among clinicians in sub-Saharan Africa.

Limitations in healthcare worker (HCW) capacity compound the burden of dual TB and HIV epidemics in sub-Saharan Africa. To fill gaps in knowledge and skills, effective continuing profession development (CPD) initiatives are needed to support practicing HCWs reach high standards of care. e-learning opportunities can bring expert knowledge to HCWs in the field and provide a flexible learning option adaptable to local settings. Few studies provide insight into HCW experiences with online CPD in the developing country context. An online survey using both close-ended and free response was conducted to HCWs in sub-Saharan Africa who completed the University of Washington (UW) School of Medicine online graduate course, “Clinical Management of HIV.” Associations between respondent characteristics (age, gender, rural/urban, job title) and learning preferences, course barriers, and facilitators with an emphasis on online courses were examined using chi-square. Covariates significant at the p < 0.05 were analyzed using multivariable logistic regression. Responses to open-ended comments were analyzed using simplified grounded theory. Of 2,299 former students, 464 (20%) HCWs completed surveys from 13 countries: about half were women. Physicians (33%), nurses (27%), and clinical officers (30%) responded mostly from urban areas (67%) and public institutions (69%). Sixty-two percent accessed the online course from work, noting that slow (55%) or limited (41%) internet as well as lack of time (53%) were barriers to course completion. Women (p < 0.001) and HCWs under age 40 (p = 0.007) were more likely to prefer learning through mentorship than men or older HCWs. Respondents favored group discussion (46%), case studies (42%), and self-paced Internet/computer-based learning (39%) and clinical mentorship (37%) when asked to choose 3 preferred learning modalities. Free-response comments offered additional positive insights into the appeal of online courses by noting the knowledge gains, the flexibility of format, a desire for recognition of course completion, and a request for additional online coursework. Online CPD opportunities were accepted across a diverse group of HCWs from sub-Saharan Africa and should be expanded to provide more flexible opportunities for self-initiated learning; however, these need to be responsive to the limited resources of those who seek these courses.
Measuring and evaluating safety management system effectiveness using Data Envelopment Analysis

Abstract In January 2015, the FAA released a congressionally mandated, final rule on Safety Management Systems (SMS) for Part 121 air carriers. Since organizations must implement SMS, often at considerable expense, a sound, valid means of measuring SMS effectiveness must be established. The purpose of this research was to develop a model to measure and test SMS effectiveness. It was constructed through a systematic series of steps, ensuring accomplishment of research objectives. While preliminary, this research demonstrates that Data Envelopment Analysis (DEA) models can be produced to help organizations measure the effectiveness of their SMS and determine how to improve SMS-related performance.
Civic Literacy and Art Education: Resisting an Interpassive Civics Through Art’s Dismeasure

This chapter contemplates the police order of neoliberalism and its impact on democratic imaginaries of creativity education. The writings of Jacques Ranciere are used to grasp the frictions and potentialities between neoliberal forms of schooling and democratic pedagogies in art education. Throughout, I ruminate on the following question: What if art education could be reconceived as a site of experimentation with democratic political engagement so that civic learning might create and transform subjectivities? In this endeavor, I examine the interdisciplinary theme of civic literacy from within the Partnership for 21st Century Skills’ Map for the Arts in order to ponder the bringing together of creativity and citizenship education as a site of potential emancipation.
From Transmission to Transaction: John Dewey's Imaginative Vision of Teaching.

ABSTRACTThis paper uses John Dewey’s ([1916]. Democracy and Education. New York: The Free Press) to explore the difference between teaching as transmission and teaching as transaction. Proceeding in three sections, the paper clarifies what Dewey understood to be the problems and promises of teaching, as well as the potential of transactionalism. Experiences from working with teachers in a Dewey-inspired school are included to illustrate the possibilities and limitations of advancing Dewey’s imaginative vision.

Species differences in bile acids I. Plasma and urine bile acid composition

Maintenance of bile acid (BA) homeostasis is essential to achieve their physiologic functions and avoid their toxic effects. The marked differences in BA composition between preclinical safety models and humans may play a major role in the poor prediction of drug-induced liver injury using preclinical models. We compared the composition of plasma and urinary BAs and their metabolites between humans and several animal species. Total BA pools and their composition varied widely among different species. Highest sulfation of BAs was observed in human and chimpanzee. Glycine amidation was predominant in human, minipig, hamster and rabbit, while taurine amidation was predominant in mice, rat and dogs. BA profiles consisted primarily of tri-OH BAs in hamster, rat, dog and mice, di-OH BAs in human, rabbit and minipig, and mono-OH BA in chimpanzee. BA profiles comprised primarily hydrophilic and less toxic BAs in mice, rat, pig and hamster, while it primarily comprised hydrophobic and more toxic BAs in human, rabbit and chimpanzee. Therefore, the hydrophobicity index was lowest in minipig and mice, while it was highest in rabbit, monkey and human. Glucuronidation and glutathione conjugation were low in all species across all BAs. Total concentration of BAs in urine was up to 10× higher and more hydrophilic than plasma in most species. This was due to the presence of more tri-OH, amidated, sulfated and primary BAs, in urine compared to plasma. In general, BA profiles of chimpanzee and monkeys were most similar to human, while minipig, rat and mice were most dissimilar to human.
Reinterpreting Structural Change in U.S. Agriculture

The structure of U.S. agriculture has been profoundly changed by the growth in specialized production units in animal agriculture, by monoculture and duoculture in field crops, and by increased dependence on export markets. Land use choices are increasingly internationalized, with emphasis shifting from domestic to global markets.

A Doctor’s War Testimony: The Four Incarnations of “Dr. Twardy”

This chapter critically compares the various embodiments of four versions of wartime diaries of Dr. Julian Aleksandrowicz, famous Polish-Jewish hematologist, humanist, and ecologist, throughout the four decades of them being written and republished. It analyzes them from the perspective of the shifting Polish-Jewish identities through which the author worked in order to achieve a consensus of his own final identity. Various aspects of Dr. Aleksandrowicz’s war activities are emphasized in different ways in the consecutive editions of his memoirs, and his choices of emphases signal a dynamic work of subjective memory in his creation of an identity for himself. By referring this development of identity to contemporary stages of the socio-political and historical reality of postwar Poland, this chapter traces the complex path that followed in the wake of the process of assimilation and acculturation that might have typified a medical section of Polish-Jewish intelligentsia remaining in Poland after the war.

Returning to the Source: Rituals of Justice and Philosophical Anthropology in Post-Genocide Rwanda

This essay explores: 1) the relationship between the calls of theorists/activists Frantz Fanon and Amilcar Cabral for post colonial African governments to develop systems of social meaning beyond western colonial forms; 2) the influence of indigenous African philosophical systems’ conception of the “human” in the process of developing new systems of thought and meaning; and 3) how the Rwandan judicial system and philosophy of the “Gacaca Council” reflects the post-genocide Rwandan state’s practical and philosophical need to develop systems of judgment reflective of the society's vision of itself.

Culture, Sociology of

Abstract Culture is constitutive of classical sociology and implicit in much postwar European sociology. Postwar American sociology began to consider culture in the 1970s with a focus upon arts. In the 1980s as the work of prominent European sociologists disseminated in translation, a global cultural turn began. Three approaches to cultural analysis have evolved in the last 20 years: first, culture is a quantifiable variable and amenable to the claims of science; second, drawing inspiration from French social theory culture is a practice of boundary formation and evaluation; and third, culture is a narrative read in ritual and performance.
A motor-driven adjustable prosthetic socket operated using a mobile phone app: A technical note.

Abstract Sockets that allow incremental size adjustment during ambulation may help prosthesis users improve management of their changes in limb volume and the quality of their prosthetic fit. A platform system was developed that allowed people with trans-tibial limb loss to adjust the radial positions of socket panels during ambulation in small increments via a motor mounted beneath the socket. The motor altered the length of a cable running through the socket panels according to commands communicated from a mobile phone. A proportional–integral–derivative controller adjusted the voltage applied to the motor via pulse-width modulation to achieve target settings. Bench test results showed that when the system was subjected to loads comparable to those expected during clinical use, maximum absolute steady state error was 0.036 mm. Treadmill testing on 16 people with trans-tibial limb amputation demonstrated that the range of cable lengths over which participants deemed fit clinically acceptable varied between 24 mm and 114 mm depending on the user. In field testing 11 of 13 participants were comfortable making socket size adjustments while walking. The developed system achieves incremental socket size adjustments appropriate for research and development of ambulatory adjustable sockets.
Endovascular Abdominal Aortic Aneurysm Repair: Does Anesthesia Type Matter?

Background Given the various types of anesthesia used for endovascular abdominal aortic aneurysm repair (EVAR), we sought to determine the effect of anesthesia type in the outcomes of elective EVAR in a large multiinstitutional healthcare maintenance organization. Methods A retrospective chart review was conducted on all elective EVAR conducted from August 2010 to August 2017 in 14 regional hospitals of Kaiser Permanente Southern California. Patients undergoing emergent, nonelective abdominal aortic aneurysm repairs, thoracoabdominal aneurysm repair, requiring conversion to open surgery or general anesthesia were excluded from the study. Basic demographic information, medical risk factors, anesthesia type, operative data, and postoperative morbidity and mortality data were obtained for univariate and multivariate statistical analysis. Results A total of 1,536 patients underwent EVAR, of which 1,206 met inclusion criteria. A total of 788 patients underwent general anesthesia, 164 patients underwent spinal anesthesia, 82 patients underwent epidural anesthesia, and 172 patients underwent local and monitored anesthesia care (AC). There was a significant difference in length of stay and operative time when comparing local/monitored AC to general anesthesia. No significant difference was noted in 30-day morbidity or mortality among the anesthesia groups. Conclusions Local and regional anesthesia is a safe and effective approach for elective EVAR.
Can scholarships provide equitable access to high-quality university education? Evidence from the Mastercard Foundation Scholars Program

Abstract This paper estimates the impact of a scholarship program—the Mastercard Foundation Scholars Program—on access to university. Using propensity score matching, the analysis finds that the Program improves access to high-quality university studies among vulnerable, disadvantaged youth, mostly from Africa—increasing timely access to university, to higher levels of study, and to studies abroad. Half of scholarship recipients studying abroad return to Africa and a third pursue graduate studies within 18 months of graduation. The Program’s collaborative approach holds promise for scaling up this and similar efforts to increase university participation among youth in African and other nations.
Innovation or Jobs? An Inconvenient Truth About Public Financing for ‘Innovation’

Public finance — whether in the form of grants, subsidies, or tax credits — is increasingly being cast as the panacea to either a world of IP and all its foibles, or a world in which innovators have insufficient incentives to undertake risky research. The idea is that, rather than supporting innovation through the gifting of exclusive rights like patents, government can use taxpayer dollars to support research and development activities directly. This article casts doubt on the notion that public finance can ever provide a suitable alternative for incentivizing innovation. It makes this point by examining financial subsidies currently offered by U.S. state governments. Each year, state governments across the U.S. purport to award billions of dollars in public financing for “innovation.” But it turns out these so-called innovation incentives typically have little to do with encouraging novelty or inventiveness. They are in reality designed to promote politically attractive goals: principally, the goal of job creation. This article identifies the phenomenon — essentially, jobs programs dressed up as innovation incentives — and reveals why it could be highly problematic for innovation policy. By diverting investment towards subject matter that is labor- intensive, these incentives may end up encouraging developments that are the opposite of “innovative,” in the ordinary sense of the word. Those who support relying more heavily on public finance as an innovation policy tool need to confront the reality that, when taxpayer money is on the line, political goals may well trump the desire to reward truly innovative endeavors.
New atomic data for Si/6+/, S/8+/ and Ar/10+/

The paper gives new atomic data, populations of excited levels, and line intensity ratios for the ions Si VII, S IX, and Ar XI of the O I isoelectronic sequence. Ten levels are included in the calculations, i.e., the levels of the 2s/2/2p/4/ and 2s2p/5/ and 2p/6/ configurations. It is noted that the calculations are done for applications to solar plasmas. The line ratios (2s/2/2p/4/3P1 - 2s2p/5/3P0) / (2s/2/2p/4/3P1 - 2s2p/5/3P1) and (2s/2/2p/4/1D2 - 2s2p/5/1P/1/) / (2s/2/2p/4/3P/1/ - 2s1p/5/3P/1/) are two of the ratios useful for electron density determination. Finally, density sensitive line ratios of Ca XIII and Fe XIX are also discussed.
Becoming a (Gendered) Dating App User: An Analysis of How Heterosexual College Students Navigate Deception and Interactional Ambiguity on Dating Apps

Scholars have worked to understand how people use dating apps as this new technology changes sexual interactions. While previous scholarship has examined how people interact with one another on dating platforms, less attention has been paid to how people decide to adopt dating apps for personal use. This study analyzes interview data with 27 heterosexual college students in order to examine this process by asking, “how do heterosexual college students come to define dating apps as a normative dating practice?” The findings in this study suggest that both men and women work through ambiguous and deceptive online interactions. As they work through online interactions, they establish themselves as normative dating app users by aligning their experiences with their perceived potential of dating apps. The findings suggest that initially, many dating app users see the apps ‘fun’ or as a ‘game.’ Eventually, through a combination of experience and technological tools, students came to define dating apps as more convenient than in-person dating and relatively safe to use for sex and dating. The findings also suggest that while both men and women confront deception and ambiguous social interactions, gender-specific concerns strongly influence how students use dating apps. This gender difference is particularly pronounced regarding the perceived relative safety of dating apps. Specifically, men define dating apps as fun albeit superficial, whereas women define dating apps as potentially dangerous.
Untethered Lecture Capture: Stimulating Educational Affordances Through Technology-Enhanced Teaching.

ABSTRACT Untethered Lecture Capture (ULC) permits faculty to be freely mobile in the classroom (untethered) and synchronously create reusable learning media assets (lecture capture) through mobile technology resources. Integrating the cognitive theory of multimedia instruction with ULC creates affordances that facilitate learning. Anecdotal student comments indicate ULC supports accessibility, enhances personalized self-paced learning, and creates opportunities for academic success. Untethered faculty teach among students, enhancing in-class focus, time-on-task, and student-faculty engagement. Although all students may benefit from ULC teaching strategies, first-generation students and students whose first language is not English reported increased confidence, coupled with decreased stress.

Separacja i rozwód (podobieństwa i różnice)

This article consists of theoretical considerations on legal issues of divorce and separation. Except for financial and legal issues that are settled in Family and Guardianship Code, legal and procedural issues are also included, while these two institutions are presented on displaying their similarities and differences. Some doctrine statements are trying to compare separation with a divorce, pointing out pros and cons of these solutions, although, in reality, each of these institutions is completely different, has different goals, is also protecting different rights of the married ones.
