Les maîtres de la Dombes. Considérations sur la noblesse féodale des pays lyonnais à travers l’exemple des seigneurs de Villars (XIe-XIIe siècles)
Authors: Ganivet Pierre
Published: March 2015

Die Herren der Dombes : Überlegungen zum Feudaladel im Raum Lyon am Beispiel der Herren von Villars (11. und 12. Jh.).

Bis heute wissen wir nur wenig über die Adelsfamilien, Burgen und Feudalherrschaften rings um Lyon im 11. und 12. Jh. In den letzten Jahrzehnten beschäftigten sich die Historiker im Wesentlichen mit den zahlreichen Kirchen und Abteien sowie deren Vormacht über den Lyoner Raum. Hier kann man die Studien von Martin Heinzelmann (seine Bischofsherrschaft) zur Spätantike, von Marie-Thérèse Lorcin (Campagnes de la région lyonnaise aux XIVe-XVe siècles) und von Michel Rubellin zur karolingischen Renaissance erwähnen. Man nahm lange an, dass die Schwäche der weltlichen Macht der besondere Wesenszug der Lyoner Geschichte im Mittelalter bilde. Nur im Forez und in der Herrschaft Beaujeu fanden die Historiker Ausnahmen und erklärten sie durch ihre geografische Lage am Rande der Lyoner Diözese. Vielleicht stammt diese Vision aus der Tatsache, dass man lange nur einen eng begrenzten Raum rings um die Bischofsstadt untersucht hat. Wenn man sich für das ganze Territorium des alten pagus Lugdunensis interessiert, findet man andere Adelsherrschaften als die beiden oben genannten. Ungefähr dreißig Adelsgeschlechter lassen sich allein für das 11. und 12. Jh. nachweisen. Sie besaßen hier meist als Allodium eine oder mehrere Burgen. Später verschwinden viele von ihnen aus unseren Quellen. Die mächtigen Geschlechter des Forez und der Herrschaft Beaujeu übernehmen ihre Stellungen und ihren Besitz, sodass ihre Anzahl nach 1200 stark abnimmt. Und trotzdem hat die Feudalzeit hier tiefe Spuren hinterlassen. Sie erklären warum die Grafschaft Lyon stark verkleinert wurde und später eigentlich nur noch die Kernregion des alten römischen pagus bildet. Der Autor untersucht in dieser Studie dieses Lyoner Phänomen am Beispiel der Herren von Villars, die im 11. und 12. Jh. die Herren der Dombes waren.
Modalités et conséquences socio-économiques de la privatisation des biens communaux dans le Gard (1793-1819)
Authors: Plack Noelle
Published: March 2015

Cet article examine les modalités et les conséquences de la privatisation des biens communaux dans le département du Gard. Le décret jacobin du 10 juin 1793 a autorisé la partition des communaux, mais il fut suivi de deux lois adoptées en réaction à ce décret, qui a finalement déplacé des quantités considérables des biens dans le domaine privé. Conformément à la loi du 9 ventôse an XII et à l’ordonnance royale du 23 juin 1819, de nombreux biens communaux sont privatisés dans le Gard, par bail ou par vente. Les données de l’application de ces lois montrent qu’une grande quantité de cette terre nouvellement privatisée a été plantée en vignes. Ce constat est important car il nous éclaire sur la croissance de la surface viticole avant 1850 et parce qu’il revient sur la vision plus pessimiste des historiens qui remettent en question l’impact socio-économique de la Révolution française.
Pour une relecture de la Vita Caesarii : le rôle politique de l’évêque d’Arles face aux représentants des royaumes burgonde, wisigothique et ostrogothique
Authors: Delaplace Christine
Published: March 2015

Releyendo la Vita Cesarii : el papel político del obispo de Arles frente a los representantes de los reinos burgundio, visogodo y ostrogótico.

Este artículo retoma el texto de la Vita Cesarii para tratar de entender lo que ha sido ocultado en el papel político de cesaire de Arles, obispo que ha sufrido tres dominaciones sucesivas teniendo que adaptarse a las mismas. la exposición se ciñe a la cronología, respetando la sucesión del libro I de la Vita redactado por allegados de cesaire, unos siete años después de su muerte. el problema de las «traiciones » del obispo de Arles se enfoca así en el contexto de los disturbios de los principios del siglo VI. este estudio se propone llamar la atención sobre la ocultación en la hagiografía, e incluso la reescritura de ciertas realidades características de las dominaciones políticas que se sucedieron en las ciudades de la Galia meridional en tiempos de la Antigüedad tardía.
Larzac : du refus local de l’extension du camp militaire au soutien à la « cause du causse » (1971-1981)
Authors: Terral Pierre-Marie
Published: March 2015

En 1971, le plateau du Larzac, jusque-là inconnu, accède à une soudaine notoriété lorsque est annoncée l’extension du camp militaire situé en son coeur. trois ans après mai 68 et dans un contexte de revendication occitane, les agriculteurs locaux s’engagent pas à pas dans une protestation, réussissant durant une décennie (1971-1981) à mobiliser autour d’eux un large et hétéroclite mouvement de soutien, jusqu’à une décision politique leur donnant « gain de causse »…
La symbolique à fleur de peau. Dessus de la politique et dessous de la politisation dans le Midi de la France (1814-1851)
Authors: Triomphe Pierre
Published: March 2015

Skin-deep Symbols. The up side of politics and the down side of politicization in the French Midi (1814-1851).

From 1814 to 1851, marking bodies and clothes constituted a specific way of exhibiting one’s political partisanship. Such marks found a priviledged terrain for expression in Southern France where the richness of folklore and traditions of radicalism often gave it a spectacular character. This self politicization was expressed in multiple ways : tatoos, colors, floral symbols… After an inventory of their forms, the article will re-examine the signification of these signs as a way of trying to understand the question of the politicization of popular classes and women. Throughout the period, and more specifically during political crises, self politicization appeared as a stage in the affirmation of the individual within societies that were still marked by the weight of communal identities, and as one of the manners of constructing a national political space.
Boire, manger, célébrer et voter : fêtes et banquets républicains en Corse, XIXe-XXe siècles
Authors: Pellegrinetti Jean-Paul
Published: March 2015

À partir de 1881, date à laquelle la République s’installe en Corse, des méthodes et des pratiques politiques nouvelles, pour l’implantation et la diffusion de l’idée républicaine, se mettent en place dans l’île, malgré le poids des structures claniques et clientélistes. À partir de l’utilisation de registres festifs, la stratégie des républicains consiste dans la rupture significative de l’ordre quotidien. La fête politique, son imagerie et sa symbolique se doivent de créer une conscience collective d’appartenance partisane. Ces moments d’intimité partagée et d’intemporalité, accentués par l’intensité des bruits et des sons (feux d’artifice, fanfare, mousqueterie) et par la profusion du «matériel » républicain (guirlandes, arcs de triomphe et, bien sûr, Mariannes), deviennent, dans la Corse de la fin du XIXe siècle, les registres d’expression des fêtes de la République et de ses usages politiques.
A genotyping protocol for multiple tissue types from the polyploid tree species Sequoia sempervirens (Cupressaceae)
Authors: Narayan Lakshmi , Dodd Richard S. , O'Hara Kevin L.
Published: March 2015

Premise of the study:

Identifying clonal lineages in asexually reproducing plants using microsatellite markers is complicated by the possibility of nonidentical genotypes from the same clonal lineage due to somatic mutations, null alleles, and scoring errors. We developed and tested a clonal identification protocol that is robust to these issues for the asexually reproducing hexaploid tree species coast redwood (Sequoia sempervirens).

Methods:

Microsatellite data from four previously published and two newly developed primers were scored using a modified protocol, and clones were identified using Bruvo genetic distances. The effectiveness of this clonal identification protocol was assessed using simulations and by genotyping a test set of paired samples of different tissue types from the same trees.

Results:

Data from simulations showed that our protocol allowed us to accurately identify clonal lineages. Multiple test samples from the same trees were identified correctly, although certain tissue type pairs had larger genetic distances on average.

Discussion:

The methods described in this paper will allow for the accurate identification of coast redwood clones, facilitating future studies of the reproductive ecology of this species. The techniques used in this paper can be applied to studies of other clonal organisms as well.
Electromagnetic enhancement of ordered silver nanorod arrays evaluated by discrete dipole approximation
Authors: Wei Guoke , Wang Jinliang , Chen Yu
Published: March 2015

The enhancement factor (EF) of surface-enhanced Raman scattering (SERS) from two-dimensional (2D) hexagonal silver nanorod (AgNR) arrays were investigated in terms of electromagnetic (EM) mechanism by using the discrete dipole approximation (DDA) method. The dependence of EF on several parameters, i.e., structure, length, excitation wavelength, incident angle and polarization, and gap size has been investigated. “Hotspots” were found distributed in the gaps between adjacent nanorods. Simulations of AgNR arrays of different lengths revealed that increasing the rod length from 374 to 937 nm (aspect ratio from 2.0 to 5.0) generated more “hotspots” but not necessarily increased EF under both 514 and 532 nm excitation. A narrow lateral gap (in the incident plane) was found to result in strong EF, while the dependence of EF on the diagonal gap (out of the incident plane) showed an oscillating behavior. The EF of the array was highly dependent on the angle and polarization of the incident light. The structure of AgNR and the excitation wavelength were also found to affect the EF. The EF of random arrays was stronger than that of an ordered one with the same average gap of 21 nm, which could be explained by the exponential dependence of EF on the lateral gap size. Our results also suggested that absorption rather than extinction or scattering could be a good indicator of EM enhancement. It is expected that the understanding of the dependence of local field enhancement on the structure of the nanoarrays and incident excitations will shine light on the optimal design of efficient SERS substrates and improved performance.
Psychiatric Rehabilitation in Residential Treatment Settings
Authors: Drake Robert E. , Strickler David C. , Bond Gary R.
Published: March 2015

Residential treatment settings can provide safety, stabilization, and treatment. Many also provide psychiatric rehabilitation, defined here as enhancement of supports and skills. Long-term residential treatment must balance potential benefits and harms. Critical issues include dependence, community inclusion, transfer of skills, supported employment and education, psychiatric medications, and perverse incentives. Guidelines to address each of these issues include emphasis on independence, recovery, living in the community, informed decision-making, developing skills and supports in real-world settings, pursuing education and employment in normal school and work settings, developing healthy relationships outside of professional staff, minimizing medication exposure, and minimizing time in segregated residential programs.

Cognitive Remediation in a Residential Rehabilitation Setting
Authors: Medalia Alice , Saperstein Alice M.
Published: March 2015

Impairment in cognition is a prevalent and functionally significant symptom in people with serious and persistent mental illness who reside in rehabilitative residential settings. Difficulties in information processing may limit the extent to which an individual with serious and persistent mental illness will be able to meet their personal recovery goals, thus indicating a need for specialized intervention. Cognitive remediation (CR) is a behavioral treatment that directly targets the cognitive skills that have been empirically linked to functional skills and community outcomes. Residential programs offer a therapeutic milieu that is amenable to integrating CR using the treatment parameters that have been identified in empirical studies as contributing to CR efficacy. This article describes potential barriers to CR implementation and how those barriers can be overcome—optimally supporting residents’ ability to learn the skills critical for meeting functional goals and for supporting personal recovery.

Nursing Advocacy for Women Veterans and Suicide
Authors: Conard Patricia L. , Armstrong Myrna L. , Young Cathy , Hogan La Micha
Published: March 2015

Little is known about suicide variables in women Veterans. The authors reviewed numerous applicable health care and military literary sources regarding suicide in this population. The current article describes the surrounding circumstances, military war/conflict culture, and potential effects on women Veterans, including major collection problems with current Veteran data. Women Veterans are increasingly reporting more behavioral health issues (e.g., posttraumatic stress disorder) and attempting suicide upon civilian reintegration. Outcomes from this literature review suggest the importance of nursing advocacy to create better rapport and communication with women Veterans from Vietnam, Gulf I, Iraq, and Afghanistan wars seeking care at civilian health facilities, as some may present with suicidal ideologies.

Femtosecond Laser-Assisted Cataract Surgery Without OVD: A Prospective Intraindividual Comparison
Authors: Schargus Marc , Suckert Nathanael , Schultz Tim , Kakkassery Vinodh , Dick H. Burkhard
Published: March 2015

PURPOSE:

To compare femtosecond laser-assisted cataract surgery without the use of ophthalmic viscosurgical device (OVD) with standard phacoemulsification using OVD.

METHODS:

This was a prospective, randomized, single-center trial of 37 patients (74 eyes) diagnosed as having significant cataract in both eyes. Randomly, one eye underwent standard phacoemulsification with OVD (the OVD group); this group acted as controls. The other eye was treated with the femtosecond laser; the subsequent manual part of the procedure was performed without OVD (non-OVD group). Time of surgery, amount of fluid used during phacoemulsification, central corneal thickness, intraocular pressure, endothelial cell count, and visual acuity were documented over the 6-month follow-up.

RESULTS:

There were no major complications and no significant difference in overall surgery time (non-OVD: 375 ± 81 seconds; OVD: 362 ± 43 seconds;
P
= .713) and in the quantity of fluid passing through the eye (non-OVD: 187 ± 35 mL; OVD: 186 ± 27 mL;
P
= .952) between groups. Endothelial cell loss after 6 months was not significantly different between groups (non-OVD: −2.4%; OVD: −2.7%;
P
= .880). Central corneal thickness was not different at 1 week postoperatively between groups (non-OVD: 575 ± 45
µ
m; OVD: 573 ± 46
µ
m;
P
= .820). Three patients in the OVD group and one patient in the non-OVD group experienced intraocular pressure greater than 25 mm Hg at 1 day postoperatively. There were no significant differences in corrected distance visual acuity between groups (logMAR non-OVD: 0.024; OVD: 0.038;
P
= .461).

CONCLUSIONS:

Femtosecond laser-assisted treatment allows the cataract surgeon to perform phacoemulsification and intraocular lens implantation without the use of OVD at no additional risk to the corneal endothelium. Furthermore, there was a tendency toward fewer increases in intraocular pressure in patients treated with the femtosecond laser.

Initial Clinical Results of a New Telescopic IOL Implanted in Patients With Dry Age-Related Macular Degeneration
Authors: Hengerer Fritz H. , Artal Pablo , Kohnen Thomas , Conrad-Hengerer Ina
Published: March 2015

PURPOSE:

To evaluate the safety and efficacy of the iol-AMD technology (London Eye Hospital Pharma, London, UK), which includes two injectable, hydrophobic acrylic intraocular lenses (IOLs) in a pilot study of patients diagnosed as having cataract and dry age-related macular degeneration.

METHODS:

The cataract surgery and IOL implantation were performed after a preoperative evaluation using the iolAMD simulator in eyes with bilateral intermediate dry age-related macular degeneration. Outcomes were intraoperative and postoperative complications, subjective and objective visual acuity improvement, visual field changes, and postoperative diplopia.

RESULTS:

Three eyes of 2 patients were evaluated. The surgeries were uneventful. All eyes gained monocular reading vision at the 1-week postoperative visit. One patient with monocular implantation recognized diplopia for distance vision. Preoperative corrected distance visual acuity ranged from 20/800 to 20/125 and corrected near visual acuity was 20/800 or less. Two months after surgery, corrected distance and near visual acuities increased to levels between 20/40 and 20/25 (uncorrected distance visual acuity was 20/60 to 20/32; uncorrected near visual acuity was 20/200 to 20/25).

CONCLUSIONS:

These early results showed that the iolAMD simulator is a promising technology improving near and distance visual acuity in eyes with intermediate dry macular degeneration. The prismatic IOL effect did not lead to diplopia when implanted bilaterally. The surgery was safely performed.

LASIK Ablation Centration: An Objective Digitized Assessment and Comparison Between Two Generations of an Excimer Laser
Authors: Kanellopoulos Anastasios John , Asimellis George
Published: March 2015

PURPOSE:

To objectively define the effective centration of myopic femtosecond laser-assisted LASIK ablation pattern, evaluate the difference between achieved versus planned excimer laser ablation centration, and compare these results from two different generations of an excimer laser system.

METHODS:

The study retrospectively evaluated 280 eyes subjected to myopic LASIK. Digital image analysis was performed on Scheimpflug sagittal curvature maps (difference of preoperative to postoperative). Centration was assessed via proprietary software digital analysis of the coordinate displacement between the achieved ablation geometric center and the planned ablation center, which was the corneal vertex. Results from two different excimer laser generations (Eye-Q 400 [140 eyes] and EX500 [140 eyes]; Alcon/WaveLight, Fort Worth, TX) were compared.

RESULTS:

Radial displacement was on average 360 ± 220
µ
m (range: 0 to 1,030
µ
m) in the Eye-Q 400 laser group and 120 ± 110
µ
m (range: 0 to 580
µ
m) in the EX500 laser group (
P
< .01). The percentage of eyes with displacement of greater than 300
µ
m was 52% in the Eye-Q 400 laser group and 4% in the EX500 laser group.

CONCLUSIONS:

Displacement of ablation pattern may depend on the laser platform used. The improvement in the efficiency of centration indicates that newer generation excimer lasers with faster eye tracking and active centration control appear to achieve a significantly more accurate centration of myopic ablation patterns. The authors propose this novel, objective technique for laser refractive surgeon evaluation may point out significant outcome measures not currently used in standard metrics of refractive laser efficiency.

Evaluation of a New Controlled Point Source LED Glare Tester for Disability Glare Detection in Participants With and Without Cataracts
Authors: Epitropoulos Alice T. , Fram Nicole R. , Masket Samuel , Price Francis W. , Snyder Michael E. , Stulting R. Doyle
Published: March 2015

PURPOSE:

To determine glare-induced change during visual acuity testing in patients with and without cataract using the controlled point source light-emitting diode (LED) glare tester (EpiGlare Tester; Epico, LLC, Columbus, OH), a new medical device for identification of glare disability.

METHODS:

This prospective, multicenter study enrolled 40 patients (80 eyes with cataracts) and 49 control subjects (98 eyes without cataracts). Corrected distance visual acuity (CDVA) was measured with and without glare using the EpiGlare Tester as a glare source. Functional visual ability was evaluated using driving and glare subscales from the Refractive Status Vision Profile questionnaire. The primary efficacy measure was change in CDVA measurement with and without glare in patients with senile cataract compared to participants without cataract. Secondary efficacy measures included correlation of the CDVA change caused by functional glare disability and subjective patient and investigator assessments.

RESULTS:

CDVA reduction was greater for patients with cataract, with a mean reduction of −0.49 ± 0.3 logMAR, than for participants without cataracts at −0.13 ± 0.2 logMAR (
P
< .001). This equates to a 5-line Snellen reduction (0.49 logMAR) in patients with cataracts and a 1-line reduction (−0.13 logMAR) in patients without cataracts. Among patients with cataracts, 83% stated the device accurately represented the difficulty experienced while driving at night (
P
< .001); among participants without cataracts, 71% reported being minimally affected by glare from the device (
P
= .003).

CONCLUSIONS:

A new controlled point source LED glare tester demonstrated the adverse effect on visual acuity due to glare in patients with cataract, accurately simulated night driving glare issues for patients with cataracts, and was rated as easy to use and useful by investigators.

Comparison of Time-and-Motion Observations and Self-Reports to Capture Mobility-Related Nursing Care Activities for Hospitalized Older Adults
Authors: Yoon Ju Young , King Barbara , Pecanac Kristen , Brown Roger , Mahoney Jane , Kuo Fanglin
Published: March 2015

Mobility-related nursing care activities are provided infrequently for older adults in inpatient practice. Accurate quantification of these activities is critical to understanding patterns of delivery of nursing care and developing or redesigning work processes to improve patients’ outcomes. The current exploratory study compares two continuous data-collecting methods: (a) self-reporting and (b) time-and-motion (TAM) observation of mobility-related nursing care activities for hospitalized older adults. A total of 84 patient-level data were captured by observing 43 8-hour shifts of 14 RNs by trained research observers. RNs continuously documented all types of nursing care activities that occurred during observation shifts. The frequency and duration of mobility activities between data obtained from RNs’ self-reports and the TAM observations had poor agreement. Compared to the data from the TAM observations, RNs underreported the frequency of their mobility-related nursing care activities and overreported the duration. The authors’ data suggest that a continuous TAM observation method is recommended to obtain accurate data on nurses’ provision of mobility-related care activities to older adults.

Authors: Luo Ying Ting , Wang Hong Bin , Zhu Wen Jun , Wu Zhen , Song Hong Tu , Li Xiong
Published: March 2015

Most optical hydrogen sensors are based on light intensity measurement and light intensity detection is vulnerable to the light source output and the optical fiber arrangement. To overcome the shortcomings, an optical fiber based sensor based on fiber Bragg grating (FBG) technique which is capable to measure the concentration of hydrogen dissolved is described in this paper. To examine the availability of monitoring initial hydrogen generation, a needle-to-plate partial discharge (PD) model was setup in the lab. The results between wavelength shifts of optical hydrogen sensor well agreed with conventional dissolved gas analysis (DGA), proving a potential utilization in the detection of dissolved hydrogen in power transformer.

Published: March 2015

Rapid-response biosensing systems are necessary to counteract threats due to high-consequence pathogens. A disposable immunosensor suitable for quantitative determination of E.coli O157:H7 in pure cultures was investigated by electrochemical impedance spectroscopy (EIS). Electric responses of this biosensor for different cell concentrations at multi-frequencies were explored utilizing disposable screen-printed silver four-wire interdigitated microelectrodes (IMEs). Additionally, the best response frequency for the detection was studied, and the relationship between the impedance at this frequency and the concentrations of E.coli O157:H7 was established. The results showed that the impedance biosensor showed linearity from 1.15×103 CFU/mL to 1.15×106 CFU/mL at 100Hz, which yielded the model coefficient to 0.951.
A Rapid Anti-Collision Method for RFID Tag Identification
Authors: Zhang Hai Peng , Li Jun Jie , Chen Zi Ling , Wang Bin
Published: March 2015

In RFID system, when multiple tags transmit information in the same wireless channel simultaneously, data collisions usually occur which will reduce the identifying efficiency of RFID systems. To resolve this problem, several Dynamic Frame-Slotted ALOHA (DFSA) methods have been proposed. However, these methods are generally not capable of achieving expected performance when the number of tags is much larger or smaller than the initial frame size. Aiming to this problem, a Rapid DFSAI (RDFSAI) method was put forward based on the DFSA with interrupt (DFSAI) in this paper. Firstly, whether the frame size is adjusted or not is judged by comparing the system efficiency with the reference system efficiency. Secondly, the multiple factor of the frame size is determined by the ratio between the collision and empty slots, which leads to a seriels of different multiple factors or. As a result, the proposed RDFSAI elevates the adjustment speed of frame size and reduces the unnecessary empty and collision slots effectively. Simulation results indicate that the RDFSAI method appears better performance than the conventional methods even the tag number is increased up to 1600.
Heuristic Algorithm Based Traffic Classified Routing Algorithm in Distributed Satellite Cluster Network
Authors: Jiang Nan , He Yuan Zhi , Guo Lei
Published: March 2015

The architecture of distributed satellite cluster network (DSCN) is presented and the characteristics of DSCN topology change are illustrated. On the basis of analyzing the acquisition method of network status and route calculation, we proposed a heuristic algorithm Ant Colony Optimization (ACO) based traffic classified routing (ATCR) algorithm for DSCN. Simulation results shows that, ATCR algorithm can balance network traffic effectively, and the end-to-end delay of every traffic class is less than TCD algorithm. The end-to-end delay of traffic class A and class B is less than ACO algorithm which does not use traffic classification. ATCR has a better performance on packet delivery ratio than ACO and TCD because ATCR reduces the number of heavy load link as well as packet loss caused by congestion.

To realize the on-line quick analysis of the steady-state stability margin for the weak section of a power grid, a method of dividing the important generator groups according to the impact of the system equivalent impedance on the static stability limits of the section is presented. By using the dynamic information provided by the Wide Area Measurement System (WAMS), the center of inertia (COI) of the section of the two sides system is determined. Then the steady-state stability limits of the transmission section and the static stability margin can be calculated. The algorithm is verified by taking the out-play cross-section of West Inner Mongolia as an example, the results show that the static stability power limit and the steady-state stability margin of the section can be obtained accurately according to the presented algorithm. This algorithm can provide an effective analytical method for the online static stability security analysis of a power system.
