Survival, metabolic rates and locomotory activities of a groundwater-obligate copepod species under long-term exposures to tetrachloroethylene
Authors: Di Lorenzo Tiziana , Di Marzio Walter , Piccini Leonardo , Messana Giuseppe , Sáenz Maria , Galassi Diana 
Published: September 2018

Volatile organic compounds (VOCs) are known to potentially cause a severe change in the respiratory metabolism of freshwater species, however the effect of these contaminants on groundwater-obligate species has not been investigated to date. Tetrachloroethylene (TCE) is a VOC frequently found in the groundwater bodies of industrialized areas, even years after a contamination event because TCE degradation takes several decades to occur. Contamination from TCE is considered persistent and difficult to remediate. Its high density favors a gravity-driven vertical infiltration into groundwater bodies. The TCE threshold value is 1.1 μg/L in groundwater bodies of Italy. TCE concentration in many Italian groundwater bodies is widely over this legal limit.
In this study, we investigated the effect of 1.1 μg/L TCE on the survival, oxygen consumption, and locomotory activities of a groundwater-obligate copepod species. The specimens required for the trials were collected in the Antro del Corchia Cave (Tuscany). We measured the individual-based oxygen consumption of this species as a proxy of possible metabolic reactions to long-term (5 days) exposures to TCE at 8.0°C that is the mean annual temperature of groundwater flowing in the cave. To this end, we used a sealed glass microplate equipped with 24-planar oxygen sensor spots with optical isolation glued onto the bottom of 80-μL wells (Loligo Systems, Denmark) integrated with a 24-channel ﬂuorescence-based respirometry system (SDR Sensor Dish Reader, PreSens, Germany). The system allows simultaneous measurement of 20 replicates and 4 controls. Survival and locomotory activity assessments were performed by counting the number of alive individuals and measuring the number of moving animals in 5 mL glass vials each containing 20 individuals. Preliminary results showed a decreasing in oxygen consumption of the organisms exposed to 1.1 μg/L TCE for 5 days at 8°C respect to the control. However, neither survival nor locomotory activities appeared to have been affected by exposure to TCE. See Suppl. material 1.

As Chiapas state, México, counts on an extensive hydrography with diverse nutrimental and climatic characteristics, it therefore allows isolating and identifying microalgae with bioenergetics potential.
For this purpose, samples from 8 locations were collected, corresponding to 6 rivers, a wastewater and a springwater. The isolation of microalgae was developed for 4 weeks with 12:12 light/dark cycles. We demonstrated that the most efficient means for the isolation of microalgae of the hydrographic areas evaluated was the medium BG11 with 80.53% effectiveness. Of the microalgal consortium identified, 90% are composed of microalgae belonging to the class Chlorophycear. It was shown that another factor favouring the richness of morphotypes identified in the Santo Domingo River is associated with adequate concentrations of macroelements such as nitrates, nitrites, ammonium, phosphorus, sodium, potassium, magnesium and calcium at concentrations of 0.03 mg/l, 0.0006 mg/l, 0.08 mg/l, 0.03 mg/l, 62.93 mg/l, 5.46 mg/l, 34.52 mg/l and 48.78 mg/l respectively and microelements such as copper, zinc, iron, andmanganese at concentrations less than 0.2 mg/l in all microelements. The identified morphotypes, according to literature, have lipid contents ranging from 2 to 90%; this is of biotechnological importance for the production of biodiesel.
Enseigner, chercher, intervenir : explorer les horizons possibles de la sociologie de l’éducation au Portugal
Authors: Lima Torres Leonor , Gaio Alves Mariana , Dionísio Bruno 
Published: September 2018

Cet article présente la situation de la sociologie de l’éducation au Portugal en s’appuyant sur dix entretiens avec des spécialistes du domaine et une analyse des différents états de l’art parus depuis une dizaine d’années. La discipline est renée au Portugal avec le retour de la démocratie. Elle s’est tout de suite impliquée dans les enjeux du nouveau régime : une visée d’égalité et en même temps des objectifs de modernisation qui passaient par la formation de nouvelles élites. Cela impliquait le développement de trois secteurs : la recherche, l’enseignement et l’intervention. La recherche s’est appuyée sur une exigence théorique héritée de la tradition francophone tout en s’engageant dans les grandes enquêtes internationales qui s’inspirent plutôt des épistémologies anglo-saxonnes. L’enseignement s’est trouvé confronté à l’immense chantier que représentait la formation d’une nouvelle génération d’enseignants. L’intervention sociale a tenté d’accompagner les tensions inévitables entre les objectifs d’égalité et de performance, les réflexions sur l’organisation du système éducatif (autonomie des établissements ; mise en place du Nouveau Management Public ; risques de dérive marchande...) et de suivre en même temps l’émergence de nouvelles problématiques : la reformulation des inégalités en termes de discrimination, l’évolution des modes de socialisation de l’enfance et de la jeunesse, etc.
Les Touaregs dans les manuels scolaires du Mali : contenu et effets sur les représentations
Authors: Gardelle Linda , Adam Catherine 
Published: September 2018

Le conflit qu’a connu le Mali en 2012-2013 a permis de mettre en lumière des facteurs qui jouent un rôle dans la marginalisation ressentie par les Touaregs maliens : sous-emploi, défaut d’infrastructure, vulnérabilité sanitaire, climat d’insécurité dû aux trafiquants de drogue et aux groupes religieux extrémistes dans le Sahara. Cet article porte sur un facteur moins quantifiable et donc moins évident : la place accordée aux Touaregs dans l’imaginaire national. Elle est étudiée à travers les manuels scolaires maliens du secondaire depuis 1990. Le poids des représentations et, en particulier, celles véhiculées à l’école, dans les rapports qu’ont entretenus les Touaregs avec l’État malien depuis l’Indépendance pourrait expliquer en partie que le ciment national n’ait pas réussi à prendre.
Quels enjeux pour la critique face aux nouveaux objets de la recherche en éducation ? Quelques réflexions à partir de l’exemple québécois
Authors: LeVasseur Louis , Schwimmer Marina , Robichaud Arianne 
Published: September 2018

L’article concerne la sociologie du curriculum. Il s’intéresse à l’introduction de nouveaux contenus d’enseignement qui gagnent en popularité au sein de l’école québécoise même si certains ne font l’objet d’aucune politique ou programme ministériels. L’étude caractérise trois modèles culturels : thérapeutique, entrepreneurial et de résultat. Tous trois se réfèrent à des travaux des années 1960 et 1970 qui se situaient dans une démarche critique, mais l’analyse montre la manière dont leur apport peut être aujourd’hui récupéré dans une perspective managériale. À partir de là, les auteurs s’interrogent sur les nouveaux défis que rencontre la critique sociologique contemporaine.
Use of Continuing Education to Increase Nurses' Knowledge of Chronic Wound Care Management
Authors: Goudy-Egger Laynette , Dunn Karen S. 
Published: September 2018

Background:
Providing effective management of chronic wounds can be a major challenge for nurses practicing in health care systems. As the older adult population continues to increase, the prevalence of chronic health-related diseases that can lead to chronic wounds has also increased. Nurses have reported a lack of preparation in the management of chronic wounds.

Method:
The purpose of this pretest–posttest research designed study was to determine whether nurses' knowledge regarding current chronic wound care management would differ after attending an educational workshop that emphasized evidence-based clinical practices in chronic wound management.

Results:

Thirty-one nurses consented to participate. A statistically significant increase in nurses' knowledge was found from pretest (
M
= 13.48,
SD
= 2.49) to posttest (
M
= 16.03,
SD
= 2.21;
t
[30] = −4.50,
p
< .05). The majority of nurses reported referring patients to wound care specialists and believed they were inadequately prepared to care for patients with chronic wounds.

Conclusion:
These findings support the need for continuing education regarding changes in chronic wound care management.

Technology readiness and mobile self-service technology adoption in the airline industry: An emerging market perspective
Authors: Smit Cameron , Roberts-Lombard Mornay , Mpinganjira Mercy 
Published: September 2018

Orientation: While mobile applications are seen as the way forward for airlines and airports alike, not much is known about consumers’ readiness to adopt such self-service technologies. This is important because of lower than expected adoption rates of traditional self-service technologies (online websites and check-in kiosks) in the airline industry.Research purpose: The purpose of this study was to determine passengers’ level of technology readiness and its influence on their adoption of mobile self-service technologies in the airline industry of South Africa.Motivation for the study: To ensure the adoption of mobile self-service technologies in the airline industry, it is necessary to uncover consumers’ readiness and adoption behaviours towards such technologies.Research design, approach and method: Primary data were collected from 315 respondents using a structured questionnaire. The sample comprised South African citizens who had travelled using an airline either domestically or internationally within the previous 12 months. Regression analysis was used to test hypotheses posited in the study.Main findings: The findings showed that airline self-service mobile application adoption is influenced by technology readiness, perceived ease of use and perceived usefulness; both perceived ease of use and perceived usefulness are influenced by technology readiness; and perceived ease of use strongly influences perceived usefulness regarding airline mobile self-service application adoption.Practical/managerial implications: Effective communication aimed at enhancing the perception that airline self-service mobile applications are easy to use is essential to increase the adoption of mobile applications in the airline industry.Contribution/value-add: The article contributed by applying the TRAM construct to the use and adoption of self-service mobile applications in the airline industry. In addition, the study also integrated the recently refined TRI 2.0 into the TRAM construct (TRAM 2.0).
Proposing a Patellar Tendinopathy Screening tool following a systematic review
Authors: Morgan Sanell , Coetzee Frederik F. 
Published: September 2018

Background: Patellar tendinopathy (PT) is an overuse injury of the knee. The mechanism of injury is associated with repetitive stress on the patellar tendon of the knee as a result of explosive movement. Patellar tendinopathy is prevalent in all populations and is associated with intrinsic and extrinsic risk factors.Objectives: Primarily, the objective was to report on the intrinsic and extrinsic risk factors for PT, entailing a systematic review of the literature; the secondary objective was to use these risk factors to compile a proposed PT screening tool from the review and standard outcome measures.Method: A systematic review was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Elimination criteria of the articles included duplicates, titles, abstracts and methodological quality. The evidence was collected, characterised with regard to the intrinsic and extrinsic risk factors and summarised descriptively.Results: The search yielded 157 feasible articles prior to commencement of article elimination. Six articles were included with a mean methodological quality score of 69%. Eight intrinsic and five extrinsic risk factors were identified. These identified risk factors are all relevant to the pathology and formed the basis for a proposed PT screening tool. The Victorian Institute of Sports Assessment for Patellar Tendinopathy Questionnaire, Visual Analog Scale and the Pain Provocation Test are also included in the proposed test.Conclusion: Intrinsic and extrinsic risk factors for PT were identified, and consequently, the proposed PT screening tool was formulated for possible future testing in appropriate studies.Clinical implications: Prevention of PT through intrinsic and extrinsic risk factor identification, and implementation in the clinical setup as a possible outcome measurement tool with which to verify functional improvement in PT rehabilitation.
Modeling the effect of Ross Ice Shelf melting on the Southern Ocean in quasi-equilibrium
Authors: Liu Xiying 
Published: September 2018

Abstract. To study the influence of basal melting of the Ross Ice Shelf (BMRIS) on the
Southern Ocean (ocean southward of 35∘ S) in quasi-equilibrium,
numerical experiments with and without the BMRIS effect were performed using
a global ocean–sea ice–ice shelf coupled model. In both experiments, the
model started from a state of quasi-equilibrium ocean and was integrated for
500 years forced by CORE (Coordinated Ocean-ice Reference Experiment)
normal-year atmospheric fields. The simulation results of the last 100 years
were analyzed. The melt rate averaged over the entire Ross Ice Shelf is
0.25 m a−1, which is associated with a freshwater flux of 3.15 mSv
(1 mSv = 103 m3 s−1). The extra freshwater flux
decreases the salinity in the region from 1500 m depth to the sea floor in
the southern Pacific and Indian oceans, with a maximum difference of nearly
0.005 PSU in the Pacific Ocean. Conversely, the effect of concurrent heat
flux is mainly confined to the middle depth layer (approximately 1500 to
3000 m). The decreased density due to the BMRIS effect, together with the
influence of ocean topography, creates local differences in circulation in
the Ross Sea and nearby waters. Through advection by the Antarctic
Circumpolar Current, the flux difference from BMRIS gives rise to an increase
of sea ice thickness and sea ice concentration in the Ross Sea adjacent to
the coast and ocean water to the east. Warm advection and accumulation of
warm water associated with differences in local circulation decrease sea ice
concentration on the margins of sea ice cover adjacent to open water in the
Ross Sea in September. The decreased water density weakens the subpolar cell
as well as the lower cell in the global residual meridional overturning
circulation (MOC). Moreover, we observe accompanying reduced southward
meridional heat transport at most latitudes of the Southern Ocean.
Before and After the Deluge: A New Assessment of Clinton's Dam, 1779
Authors: Starna William A. , Hasbargen Leslie 
Published: September 2018

ABSTRACT
On the evening of August 8, 1779, soldiers knocked open the sluices of a temporary dam holding back Otsego Lake, the headwaters of the Susquehanna River. At nine o'clock the next morning they paddled and poled over 200 batteaux, heavily laden with provisions, baggage, and munitions, on the now quickened and deeper current of a river that a few days before had lain quiet. The destination of the flotilla and its accompanying foot soldiers was Tioga (Athens, PA) in preparation for a raid into Indian Country. Beyond the building of the dam and the military campaign, examined here is the dam's design, the extent to which the lake's waters were impounded, and, once opened, how effective the discharge was in carrying the batteaux downriver. Was the flood sufficient to float Clinton's batteaux, and can the contemporary reports on downstream effects, some as far away as Athens, be validated?
The East-West Divide and Frontier Efforts of the Reverend Dr. Joseph Doddridge
Authors: Richards Samuel J. 
Published: September 2018

ABSTRACT
Pennsylvania historians today rarely mention the Rev. Dr. Joseph Doddridge (1769–1826) despite his contributions as a historian, horticulturalist, author, physician, and clergyman probably best known for his first-hand account entitled Notes on the Settlement and Indian Wars of the western parts of Virginia and Pennsylvania, 1763–1783. Following his formative years at his family fort in Washington County, Doddridge contributed to development on the trans-Allegheny frontier. Despite his numerous contributions to documenting regional history, founding churches, nearly becoming first Episcopal bishop of Ohio, and cultivating civic life along the headwaters of the Ohio, Doddridge has largely vanished from accounts of Episcopalian church history. His absence reflects bias in favor of bishops and East Coast viewpoints. By starting one generation too late, Episcopalian historians favored eastern regional narratives of American history by ignoring Doddridge and championing the Philadelphia-based Rev. Jackson Kemper and the Rev. Philander Chase of Hartford, Connecticut.

Este diálogo reflexivo que apresentamos a seguir começou como uma entrevista piloto com o professor Francisco Fogaça para a pesquisa desenvolvida por Regina Halu durante seu estágio de pós-doutorado. A pesquisa buscava investigar os impactos do fenômeno da expansão da língua inglesa no mundo nas atitudes e práticas pedagógicas de professoras e professores de língua inglesa atuando em cursos de Letras. Nós vínhamos pesquisando juntos sobre formação de professores de línguas em nosso grupo de pesquisa, e já vínhamos refletindo sobre as mudanças na formação de professores e no ensino de inglês a partir do questionamento do status da língua inglesa. A entrevista foi se alongando no tempo e tomando corpo como um diálogo que veio a refletir não apenas sobre nossas atitudes e práticas como professores de Letras em tempos de inglês em expansão, mas também em temas como crenças de aprender e ensinar línguas, formação inicial e continuada de professores de inglês, soluções locais em um mundo globalizado, multilinguismo, linguicismo e inglês como meio de instrução.
Tendon Transfer Options for Trapezius Paralysis: A Biomechanical Study
Authors: Werthel Jean-David , Wagner Eric R. , Sperling John W. , Elhassan Bassem 
Published: September 2018

Introduction:
The purpose of this study was to evaluate the biomechanical effectiveness regarding scapulothoracic (ST) upward rotation of two different tendon transfer procedures involving the levator scapulae, rhomboid major, and rhomboid minor to restore the function of the paralyzed trapezius.

Methods:
Six fresh frozen hemithoraces were mounted on a custom-built apparatus. A three-dimensional electromagnetic tracking system was used to record ST upward/downward rotation of the (1) normal trapezius, levator scapulae, rhomboid minor, and rhomboid major; (2) Eden-Lange (EL) transferl and (3) a modified EL transfer (triple transfer).

Results:
The normal trapezius was found to be an upward rotator of the scapula and led to a mean ST rotation angle of 26.98°. Similarly, the modified triple transfer led to an upward rotation of the scapula, with a mean ST rotation angle of 22.23°, whereas the EL led to an initial downward rotation of the scapula to −6.69°, with a mean scapulothoracic displacement angle of 1.13°.

Discussion:
The upward rotation of the scapula from the modified transfer mimicked the function of the normal trapezius better than did the traditional EL transfer.

Outpatient Total Hip Arthroplasty in the United States: A Population-based Comparative Analysis of Complication Rates
Authors: Arshi Armin , Leong Natalie L. , Wang Christopher , Buser Zorica , Wang Jeffrey C. , SooHoo Nelson F. 
Published: September 2018

Introduction:
With healthcare expenditure in the national forefront, outpatient arthroplasty is an appealing option in select patient populations. The purpose of this study was to determine the complication rates associated with outpatient total hip arthroplasty (THA) in comparison to standard inpatient THA.

Methods:
We performed a retrospective review of the Humana subset of the PearlDiver insurance records database to identify patients undergoing THA (Current Procedural Terminology-27130 and Current Procedural Terminology-27132) as either outpatients or inpatients from 2007 to 2016. Multivariate logistic regression adjusting for age, gender, and Charlson Comorbidity Index were used to calculate odds ratios of complications among outpatients undergoing THA relative to inpatients undergoing THA.

Results:
The query identified 2,184 patients who underwent outpatient THA and 73,596 patients who underwent inpatient THA. The median age was in the 65 to 69 age group and in the 70 to 74 age group for the outpatient and inpatient cohorts, respectively (P < 0.001). Outpatients undergoing THA had a significantly lower incidence of comorbid hypertension (P < 0.001), cerebrovascular disease (P = 0.001), obesity (P = 0.017), chronic obstructive pulmonary disorder (P = 0.045), and chronic kidney disease (P = 0.049). The incidence of both outpatient THA (P = 0.001) and inpatient THA (P < 0.001) increased over the study period. After adjusting for age, gender, and Charlson Comorbidity Index, patients undergoing outpatient THA had comparable rates of all queried surgical complications, including component revision, irrigation and debridement, and hip dislocation at 1 year. Rates of postoperative medical complications were also comparable between the two cohorts.

Conclusion:
Outpatient THA is increasing in frequency nationwide and has comparable postoperative complication rates. With its potential to minimize arthroplasty care costs, outpatient THA is a safe and effective option among appropriately selected patients.
Factors Predictive of Orthopaedic In-training Examination Performance and Research Productivity Among Orthopaedic Residents
Authors: Kreitz Tyler , Verma Satyendra , Adan Alexei , Verma Kushagra 
Published: September 2018

Introduction:
Selection of qualified candidates for orthopaedic residency is necessary for growth and innovation. The purpose of this study was to determine predictors of Orthopaedic In-training Exam (OITE) performance and research productivity.

Methods:
A survey was distributed to 13 residency programs collecting demographics, United States Medical Licensing Examination (USMLE) and OITE scores, and authored publications. Associations between preresidency qualifications and OITE scores and publications were determined.

Results:
A total of 274 of 294 surveys were returned (93.2%). We found a positive correlation between USMLE step 1 and 2 scores with recent OITE percentile (P < 0.001). Preresidency authorship (P < 0.001) and postgraduate training year (P < 0.001) were independent predictors of authorship during residency, whereas USMLE step 1 score was not (P = 0.094).

Conclusion:
Candidates who perform well on the USMLE are likely to perform well on the OITE, whereas those with greater authored publications are likely to continue research during residency.
