The Soundtrack of Revolution Memory, Affect, and the Power of Protest Songs
Authors: Rosenberg Tiina 
Published: June 2013

All cultural representations in the form of songs, pictures, literature, theater, film, television shows, and other media are deeply emotional and ideological, often difficult to define or analyze. Emotions are embedded as a cultural and social soundtrack of memories and minds, whether we like it or not. Feminist scholarship has emphasized over the past decade that affects and emotions are a foundation of human interaction. The cognitive understanding of the world has been replaced by a critical analysis in which questions about emotions and how we relate to the world as human beings is central (Ahmed 2004: 5-12).
It is in this memory-related instance that this article discusses the unexpected reappearance of a long forgotten song, Hasta siempre, as a part of my personal musical memory. It is a personal reflection on the complex interaction between memory, affect and the genre of protest songs as experiences in life and music. What does it mean when a melody intrudes in the middle of unrelated thoughts, when one’s mind is occupied with rational and purposive considerations? These memories are no coincidences, I argue, they are our forgotten selves singing to us.
Du droit d'aubaine au Français Langue d'Insertion (FLI) : Évolution des modalités d'« accueil » de l'étranger
Authors: Arditty Jo 
Published: June 2013

La création du label « Français Langue d’Insertion » et les réactions qu’elle a provoquées sont l’occasion prise dans cet article pour revenir sur l’élaboration historique de notions telles que l’État, la nation, l’étranger, l’immigré, « la » langue nationale, et tenter de voir comment elles s’articulent dans la définition et l’évolution des politiques d’immigration. Parler d’immigration suppose en effet que l’on se situe à l’intérieur d’un espace dont les frontières sont définies et tenues pour légitimes et où un appareil administratif et répressif est en mesure de mettre en œuvre les lois et règlements qui constituent cette politique. Or l’État a mis des siècles à se mettre en place et ne parvient à se donner ces moyens qu’en même temps que s’élabore la notion de Nation et que se standardise la langue nationale qui en est un des critères. Ces phénomènes, concomitants et imbriqués dans la Révolution Industrielle, qui s’accomplit avec d’importants mouvements de population. De la fin du XIX e siècle à la première moitié du XX e , la « psychologie des peuples » et l’eugénisme participent au racialisme ambiant qui dénonce ceux qui, de l’intérieur ou de l’extérieur, pourraient altérer l’intégrité ethnique de la nation. Après une période qui semble marquée par le recul du racisme et la lutte contre les discriminations, des obstacles matériels aussi bien que réglementaires de plus en plus nombreux sont mis à l’immigration légale. Parmi cet arsenal, plusieurs pays utilisent la maîtrise de la langue comme prérequis, en même temps que réapparaît la rhétorique de l’inégalité des races et des civilisations.
Stabilizing and Retaining a Quality Nursing Work Force Through the Use of the Married State Preceptorship Model
Authors: Figueroa Solimar , Bulos Marlene , Forges Edwina , Judkins-Cohn Tanya 
Published: June 2013

Background:
The nursing shortage requires new graduate registered nurses (RNs) to work at the bedside, often leading to a shortened orientation period and increased stress. In the Married State Preceptorship Model (MSPM), the preceptor and the preceptee work together as the new graduate RN transitions to the bedside while maintaining safety and quality. This study explored first-year turnover rates of new graduate RNs and new graduate RNs’ and preceptors’ perceptions of the MSPM in transitioning new graduate RNs to practice.

Methods:
Focus groups and surveys were used with 108 new graduate RNs and 100 preceptors.

Results:
Four themes emerged for new graduate RNs: partnership, critical thinking, learning, and transition. A statistically significant decrease in turnover rates was seen with MSPM versus traditional precepting. Survey data found that new graduate RNs and preceptors perceived the MSPM as promoting safety and reducing anxiety.

Conclusion:
The MSPM allows organizations to retain a quality nursing work force focused on safety patient care by transitioning new graduate RNs into the practice setting.

Students’ Lived Experience in an Associate’s Degree to Baccalaureate Degree Continuation Program: Opening Doors, Opening Eyes, Opening Minds
Authors: McNiesh Susan G. , Rodriguez Lori , Goyal Deepika , Apen Lynette 
Published: June 2013

Background:
Major nursing organizations, federal agencies, and researchers are recommending that all nurses be educated to at least the baccalaureate level.

Methods:
This article reports the results of a qualitative study of the experiences of students enrolled in a direct associate’s degree to baccalaureate degree nursing program. Based on multiple small group interviews conducted during an 18-month period, a multistep interpretive analytic process was used that ultimately described themes within a holistic view of the phenomenon.

Findings:
The results showed an overarching theme of transformative change over time, centered within the “place” of the university.

Conclusion:
The study suggested that there are differences beyond additional coursework that describe a transformative process in associate’s degree to baccalaureate degree education. An atmosphere, or “space created,” for reflection on learning is significant to consider in the development of education programs.

Nurses and Nutrition: A Survey of Knowledge and Attitudes Regarding Nutrition Assessment and Care of Hospitalized Elderly Patients
Authors: Boaz Mona , Rychani Lydia , Barami Kohava , Houri Zahava , Yosef Ruth , Siag Avital , Berlovitz Yitzhak , Leibovitz Eyal 
Published: June 2013

Background:
Nurses’ knowledge and attitudes regarding nutrition care play an important role in patient nutrition assessment and intervention. This study measured the association between nutrition knowledge and attitudes about nutrition care and feeding patients among nurses working in hospital settings.

Methods:
This cross-sectional survey queried nutrition knowledge, attitudes, clinical applications, and task rankings using structured questionnaires in a representative sample of 106 nurses employed at two large government hospitals.

Results:
The mean proportion of correct responses to the nutrition knowledge questionnaire was 51.9% ± 0.1%. Nutrition care tasks, including feeding patients, performing nutrition assessment, and providing appropriate food to patients, were ranked as relatively unimportant. A significant positive association was identified between total nutrition knowledge score and the importance placed on the role of nutrition in health and disease.

Conclusion:
Nutrition education for nursing staff could improve both nutrition knowledge and willingness and confidence to perform nutrition assessment.

Distinguishing Bereavement from Depression in
DSM-5
: Evidence from Longitudinal Epidemiologic Surveys
Authors: Paksarian Diana , Mojtabai Ramin 
Published: June 2013

CME Educational Objectives

1.

Explain the rationale behind the
Diagnostic and Statistical Manual of Mental Disorders,
fourth edition (
DSM-IV
) bereavement exclusion for major depressive episode.

2.
Identify three recent, large-scale epidemiologic studies that have investigated the validity of the bereavement exclusion.

3.

Describe the most consistent difference these studies found between those who met criteria for
DSM-IV
major depression and those who did not meet criteria due to the bereavement exclusion.

The
Diagnostic and Statistical Manual of Mental Disorders,
fourth edition (
DSM-IV
) definition of mental disorder states that a disorder is not “merely an expectable and culturally sanctioned response to a particular event” and that it represents a “dysfunction in the individual.”

Because adverse experiences are a part of life, and negative emotions arise as natural and adaptive responses to these experiences, much of the psychological distress that humans experience is anticipated, culturally sanctioned, and functional. Thus, sadness is not a mental disorder in the
DSM

Pars Plana Vitrectomy Versus Combined Pars Plana Vitrectomy–Scleral Buckle for Secondary Repair of Retinal Detachment
Authors: Rush Ryan B. , Simunovic Matthew P. , Sheth Saumil , Kratz Assaf , Hunyor Alex P. 
Published: June 2013

BACKGROUND AND OBJECTIVE:
To investigate the optimal technique for repairing recurrent rhegmatogenous retinal detachments.

PATIENTS AND METHODS:
A 2-year retrospective review of recurrent rhegmatogenous retinal detachments by 23-gauge pars plana vitrectomy (PPV) or combined 23-gauge PPV with encircling scleral buckling was performed. The primary outcome was anatomical success. The secondary outcome was the likelihood of achieving a final best corrected visual acuity of 6/12 or better at 6-month follow-up.

RESULTS:
Anatomical success was achieved in 65.2% (95% CI, 53.4% to 75.4%) of the PPV group versus 74.3% (95% CI, 57.9% to 85.8%) of the PPV–scleral buckling group with one additional procedure (not statistically significant). There was no significant difference in the likelihood of achieving a final acuity of at least 6/12 between groups at 6-month follow-up.

CONCLUSION:
The results of our study do not demonstrate a superiority of method of primary repair, or of one method of secondary repair, over another.

Evolution of tree killing in bark beetles (Coleoptera: Curculionidae): trade-offs between the maddening crowds and a sticky situation
Authors: Lindgren B.S. , Raffa K.F. 
Published: June 2013

AbstractBark beetles (Coleoptera: Curculionidae: Scolytinae) play important roles in temperate conifer ecosystems, and also cause substantial economic losses. Although their general life histories are relatively similar, different species vary markedly in the physiological condition of the hosts they select. Most of ∼6000 known species colonise dead or stressed trees, a resource they share with a large diversity of insects and other organisms. A small number of bark beetle species kill healthy, live trees. These few are of particular interest as they compete directly with humans for resources. We propose that tree killing evolved when intense interspecific competition in the ephemeral, scarce resource of defence-impaired trees selected for genotypes that allowed them to escape this limitation by attacking relatively healthy trees. These transitions were uncommon, and we suggest they were facilitated by (a) genetically and phenotypically flexible host selection behaviours, (b) biochemical adaptations for detoxifying a wide range of defence compounds, and (c) associations with symbionts, which together aided bark beetles in overcoming formidable constitutive and induced host defences. The ability to detoxify terpenes influenced the evolutionary course of pheromonal communication. Specifically, a mate attraction system, which was exploited by intraspecific competitors in locating poorly defended hosts, became a system of cooperative attack in which emitters benefit from the contributions responders make in overcoming defence. This functional shift in communication was driven in part by linkage of beetle semiochemistry to host defence chemistry. Behavioural and phenological adaptations also improved the beetles’ abilities to detect when tree defences are impaired, and, where compatible with life history adaptations to other selective forces, for flight to coincide with seasonally predictable host stress agents. We propose a conceptual model, whereby the above mechanisms enable beetles to concentrate on those trees that offer an optimal trade-off between host defence and interspecific competition, along dynamic gradients of tree vigour and stand-level beetle density. We offer suggestions for future research on testing elements of this model.
Control of T Cell Fates and Immune Tolerance by p38α Signaling in Mucosal CD103+ Dendritic Cells
Authors: Huang Gonghua , Wang Yanyan , Chi Hongbo 
Published: June 2013

Abstract
Dendritic cells (DCs) play a crucial role in launching protective adaptive immunity against pathogens while maintaining immune tolerance to self-Ags. However, how intracellular signaling pathways program DCs to mediate tolerogenic responses remains largely unexplored. In this study, we describe that p38α signaling in CD103+ mesenteric lymph node DCs reciprocally regulates the differentiation of anti-inflammatory induced regulatory T cells and proinflammatory Th1 cells from naive precursors and promotes mucosal tolerance. Deficiency of p38α in CD103+ DCs inhibited the generation of induced regulatory T cells while promoting Th1 cell development in a TGF-β2–dependent manner. Consequently, loss of p38α in DCs prevented induction of oral tolerance in vivo. Moreover, p38α in CD103+ DCs was required for optimal expression of retinaldehyde dehydrogenase, a key enzyme for retinoic acid synthesis, which in turn imprinted gut-homing receptors on responding T cells. Consistent with a crucial role of p38α to program the tolerogenic activity of CD103+ DCs, such DC subset contained constitutive activity of p38α and abundant expression of TGF-β2 and retinaldehyde dehydrogenase. Our studies identify a key mechanism of DC-mediated coupling of T cell differentiation and trafficking that orchestrates mucosal immune tolerance.
Arbitrage homogénéité / taille des segments : proposition d’une approche pour les PME africaines1
Authors: Anasse Augustin 
Published: June 2013

Homogénéité et taille des segments sont deux conditions essentielles de la segmentation des marchés. Cependant, ces deux conditions sont souvent antinomiques : plus la taille d’un segment est importante, plus le segment en question est hétérogène et vice versa. Les responsables marketing ont donc besoin d’outils pour réaliser le compromis entre homogénéité et taille des segments. Cet article propose ainsi aux PME africaines une méthode simple et adaptée à leurs exigences.
Adaptive control of homogeneous charge compression ignition engines
Authors: Chiang Chia‐Jui , Chou Chih‐Cheng , Lin Jian‐Hong 
Published: June 2013

SUMMARYThis paper presents an adaptive controller, which maintains consistent ignition timing control of a gasoline homogeneous charge compression ignition engine with high dilution in the presence of uncertainty or unknown variation in plant parameters such as exhaust runner wall temperature and cylinder charge properties. The control of the combustion timing is based on manipulating the charge temperature through internal dilution, which is achieved by controlling the lift of a secondary opening of the exhaust valves, also known as the rebreathing lift. The adaptive controller is designed on the basis of a simplified bilinear parametric model, which contains only the cycle‐to‐cycle combustion timing dynamics. Implementation of the designed adaptive controller involves feedforward of the injected fuel and feedback of the combustion timings CA50 and CA90 when 50% and 90% of energy are released, respectively, which alleviates the impact of inevitable errors in estimation of in‐cylinder charge properties such as temperature, pressure, and compositions. It is shown through convergence analysis and closed‐loop simulation of a full‐order engine model that the adaptive controller is able to drive the combustion timing CA50 to desired set points by stabilizing the bilinear dynamics when plant parameters are changing.

Published: June 2013

ObjectiveWhile chronic hypoxia has been recognized as the principal causative factor for decreasing birth weight at high altitude, unknown is whether fetal fat accretion and vascular function are affected.MethodsColorado women with normal singleton pregnancies (18 Denver residents, 1,600 m; 24 Leadville residents, 3,100 m) were studied longitudinally from 20 to 36 weeks gestation. Fetal biometry was used to obtain axial images for assessing mid‐upper arm and mid‐thigh subcutaneous tissue mass (MUA and MUL SQ) and Doppler waveform analysis conducted to measure indices of vascular function in the fetal umbilical arteries (UmbA), umbilical vein (UmbV), middle cerebral artery (MCA), and ductus venosus (DV). SAS PROC MIXED was used to compare altitudes with P < 0.05 considered significant and trends present when 0.05 < P < 0.10.ResultsThe 3,100 m vs. 1,600 m babies weighed less at birth. Third trimester fetal biometry, MUA SQ and MUL SQ were somewhat lower, but neither the biometry nor the SQ altitudinal differences attained statistical significance. Greater prepregnant maternal BMI tended to decrease MUA SQ (P = 0.07) and increase MUL SQ (P = 0.07). UmbA S/D ratios decreased and UmbV flow increased with advancing gestation (both P < 0.001). Altitude did not affect the UmbA or MCA systolic/diastolic ratios (S/D), MCA peak‐systolic velocity, UmbV flow, or the DV systolic/atrial flow ratio.ConclusionThe hypoxia of residence at high compared to moderate altitude lowered birth weight but did not significantly alter MUA or mid‐thigh fetal subcutaneous tissue mass or Doppler indices of vascular function.

Cranial morphological variation among contemporary Mexicans: Regional trends, ancestral affinities, and genetic comparisons
Authors: Hughes Cris E. , Tise Meredith L. , Trammell Lindsay H. , Anderson Bruce E. 
Published: June 2013

ABSTRACTGenetic research has documented geographical variation within Mexico that corresponds to trends in ancestry admixture from postcolonial times on. The purpose of this study is to determine whether craniometric variation among contemporary Mexicans is comparable to that reported in genetic studies. Standard osteometric measurements were taken on 82 male crania derived from forensic cases, with geographic origins of the specimens spanning over two‐thirds of Mexico's states. To study similarities in regional clustering patterns with genetic data, k‐means clustering analyses were performed, followed by chi‐square tests of association between cluster assignments and geographic region of origin. Normal mixtures analyses were performed, centered on three “ancestral” sample proxies to estimate classification probability to each ancestry. The results demonstrate that the cranial morphological sample data cluster similarly to the regional groupings inferred from the genetic data. Additionally, the results indicate a gradient trend in population structure for contemporary Mexicans, with the proportion of Amerindian ancestry increasing from North to South while, conversely, European ancestry proportion estimates increase from South to North. Furthermore, the probabilities for classification of African ancestry remained low across the regions, again reflecting the results for the genetic data. Cranial morphological variation is well aligned with the genetic data for describing broad trends among Mexican populations, as well as yielding comparable estimates of general ancestry affiliations that reflect Mexico's history of Spanish contact and colonialism.

Foaming of polypropylene with supercritical carbon dioxide: An experimental and theoretical study on a new process
Authors: Ding Jie , Ma Weihua , Song Fujiao , Zhong Qin 
Published: June 2013

ABSTRACTA new process was used to foam polypropylene (PP) with batch foaming technique with supercritical carbon dioxide (scCO2) as the blowing agent. Comparing with the conventional process, the new one takes less time to foam and the foaming temperature range is much broader, which is about 2.5 h and 55°C, respectively. An activation model was established on the basis of mass equilibrium, this model was combined with classical nucleation theory and S‐L EOS model to explain foaming behaviors of PP and simulate the cell nucleation and cell diameter. A satisfactory agreement between calculated and experimental values was obtained. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 130: 2877–2885, 2013
Ligand Binding Promiscuity of Human Liver Fatty Acid Binding Protein: Structural and Dynamic Insights from an Interaction Study with Glycocholate and Oleate
Authors: Favretto Filippo , Assfalg Michael , Gallo Mariana , Cicero Daniel Oscar , D'Onofrio Mariapina , Molinari Henriette 
Published: June 2013

AbstractHuman liver fatty acid binding protein (hL‐FABP) has been reported to act as an intracellular shuttle of lipid molecules, thus playing a central role in systemic metabolic homeostasis. The involvement of hL‐FABP in the transport of bile salts has been postulated but scarcely investigated. Here we describe a thorough NMR investigation of glycocholate (GCA) binding to hL‐FABP. The protein molecule bound a single molecule of GCA, in contrast to the 1:2 stoichiometry observed with fatty acids. GCA was found to occupy the large internal cavity of hL‐FABP, without requiring major conformational rearrangement of the protein backbone; rather, this led to increased stability, similar to that estimated for the hL‐FABP:oleate complex. Fast‐timescale dynamics appeared not to be significantly perturbed in the presence of ligands. Slow motions (unlike for other proteins of the family) were retained or enhanced upon binding, consistent with a requirement for structural plasticity for promiscuous recognition.
CO2/CH4 Separation by Adsorption using Nanoporous Metal organic Framework Copper‐Benzene‐1,3,5‐tricarboxylate Tablet
Authors: Asadi T. , Ehsani M. R. , Ribeiro A. M. , Loureiro J. M. , Rodrigues A. E. 
Published: June 2013

AbstractEquilibrium data for carbon dioxide and methane adsorption on nanoporous metal organic framework Cu‐BTC powder and tablets were measured in a magnetic suspension balance in the temperature range of 308–373 K and a pressure range of 0–7 bar and fitted with Langmuir model. The tablets adsorption loading is 0.63 mol kg–1 for methane and 3.1 mol kg–1 for carbon dioxide at 1 bar and 308 K, while these values are 0.77 and 3.9 mol kg–1 for powder in the same conditions. Isosteric heats of adsorption were 22.8 and 15.0 kJ mol–1 for carbon dioxide and methane, respectively, on both adsorbents, which indicates a strong adsorption of carbon dioxide. Also, single and binary breakthrough curves were measured in the same temperature range and atmospheric pressure by using Cu‐BTC tablets as adsorbent. A complete model was used in the simulation of breakthrough curves and good agreement was observed with experimental data.
