Microbial Fuels Cell-Based Biosensor for Toxicity Detection: A Review
Authors: Zhou Tuoyu , Han Huawen , Liu Pu , Xiong Jian , Tian Fake , Li Xiangkai
Published: September 2017

With the unprecedented deterioration of environmental quality, rapid recognition of toxic compounds is paramount for performing in situ real-time monitoring. Although several analytical techniques based on electrochemistry or biosensors have been developed for the detection of toxic compounds, most of them are time-consuming, inaccurate, or cumbersome for practical applications. More recently, microbial fuel cell (MFC)-based biosensors have drawn increasing interest due to their sustainability and cost-effectiveness, with applications ranging from the monitoring of anaerobic digestion process parameters (VFA) to water quality detection (e.g., COD, BOD). When a MFC runs under correct conditions, the voltage generated is correlated with the amount of a given substrate. Based on this linear relationship, several studies have demonstrated that MFC-based biosensors could detect heavy metals such as copper, chromium, or zinc, as well as organic compounds, including p-nitrophenol (PNP), formaldehyde and levofloxacin. Both bacterial consortia and single strains can be used to develop MFC-based biosensors. Biosensors with single strains show several advantages over systems integrating bacterial consortia, such as selectivity and stability. One of the limitations of such sensors is that the detection range usually exceeds the actual pollution level. Therefore, improving their sensitivity is the most important for widespread application. Nonetheless, MFC-based biosensors represent a promising approach towards single pollutant detection.
Reasons to Adopt ISO 50001 Energy Management System
Authors: Marimon Frederic , Casadesús Martí
Published: September 2017

Purpose: The main aim of this paper is to analyze the relationships between the corporate motivations that lead organizations to establish the ISO 50001 Energy Management System (EnMS) standard, and the difficulties and benefits derived from its adoption. Design/methodology/approach: Three independent exploratory factor analyses (EFA) were conducted in order to identify (i) sources of motivation: social requirements, ecology drivers, and competitive advantage; (ii) the difficulties of an ISO 50001 adoption: operational difficulties and organizational difficulty; and (iii) types of benefits: ecological benefits and operational benefits. In a second step, an exploratory path analysis, performed through Structural Equation Modeling (SEM), was used to analyze the relations among motivation, difficulties, and benefits related to the adoption of the ISO 50001 standard. Findings: Social requirements explain operational difficulties, which in turn impacts on operational benefits. Ecology drivers are directly related to ecological benefits. Organizational difficulties have an inverse relationship with operational and ecological benefits. Operational difficulties are related to operational benefits and ecological benefits. Research limitations/implications: The questionnaire was disseminated to 87 Spanish companies with ISO 50001 certification. Managers and other practitioners such as consultants, auditing companies, and official organizations in charge of developing standards might find useful implications. Originality/value: The standard was published in 2011 by the International Organization for Standardization (ISO). This paper contributes to assessment of the benefits of the standard by collecting information directly from the pioneer organizations that have adopted it, and provides clues on how to implement the standard and improve it in future.

Published: September 2017

Recent declines in pollinator populations have led to widespread concern due to their impact on food/crop production and the environment. Contrary to growing interest in the use of insecticides in urban landscapes, the relationship between pollinator-related eco-labels, visual attention, and preferences for plants is less understood. The present study combines eye tracking and stated preference experiments to examine the effects of pollinator-related labels on consumers’ preferences and willingness to pay. Results show that the pollinator-friendly attribute positively correlates with consumers’ purchasing decisions and visual attention supports that relationship. Implications of mandatory labeling of pesticide content for the horticultural industry are discussed.
Carbon Reduction Strategies Based on an NW Small-World Network with a Progressive Carbon Tax
Authors: Wu Bin , Huang Wanying , Liu Pengfei
Published: September 2017

There is an increasingly urgent need to reduce carbon emissions. Devising effective carbon tax policies has become an important research topic. It is necessary to explore carbon reduction strategies based on the design of carbon tax elements. In this study, we explore the effect of a progressive carbon tax policy on carbon emission reductions using the logical deduction method. We apply experience-weighted attraction learning theory to construct an evolutionary game model for enterprises with different levels of energy consumption in an NW small-world network, and study their strategy choices when faced with a progressive carbon tax policy. The findings suggest that enterprises that adopt other energy consumption strategies gradually transform to a low energy consumption strategy, and that this trend eventually spreads to the entire system. With other conditions unchanged, the rate at which enterprises change to a low energy consumption strategy becomes faster as the discount coefficient, the network externality, and the expected adjustment factor increase. Conversely, the rate of change slows as the cost of converting to a low energy consumption strategy increases.
Corporate Environmental Responsibility and Environmental Non-Governmental Organizations in China
Authors: Yang Zhaojun , Liu Weihao , Sun Jun , Zhang Yali
Published: September 2017

In China, environmental non-governmental organizations (ENGOs) play an important supervisory role to address ecological issues together with government regulation and enterprise implementation. This study examines the effect of ENGO presence on corporate environmental responsibility (CER) performance, along with internal factors as covariate variables. With a sample of 677 enterprises, it operationalizes the independent variable in terms of the number of ENGOs within certain distances from each enterprise, and the dependent variable based on the corporate social responsibility report using the specific criteria in the Global Reporting Initiative (GRI) sustainability reporting guidelines. The results of Tobit regression analyses indicate that ENGO presence is conducive to CER performance, and asset size, power concentration, and industry type also make differences. The findings suggest that ENGOs are helpful in solving environment issues by bridging the gap between private and public sectors. Theoretical and practical implications are discussed.

Published: September 2017

The objective of the study was to describe self-reported health symptoms, the use of personal protective gear and clothing and poor safety procedures when applying pesticides among farm workers. A total of 128 adult farm workers were interviewed using a structured questionnaire during the farming season. The commonly used pesticides included profenofos, mancozeb, chlorpyrifos, cypermethrin, deltamethrin, permethrin, lambda-cyhalothrin, endosulfan and carbosulfan. The majority (>90%) of farm workers used no personal protective clothing while handling pesticides. More than one-third of farm workers ate and drank without washing their hands following pesticide handling, while a smaller number smoked or chewed gum. Wearing special boots during pesticide application was found to reduce the risk of skin rash (OR = 0.2, 95% CI: 0.06–0.66), whereas smoking when applying pesticides increased the risk of chest pain occurrence (OR = 4.0, 95% CI: 1.14–15.43), as well as forgetfulness (OR = 4.0, 95% CI: 1.30–14.02). Chewing gum and eating when applying pesticides was associated with diarrhoea (OR = 11.0, 95% CI: 1.80–6.84 and OR = 7.0, 95% CI: 1.27–3.67 respectively). The increased self-reported prevalence of post-exposure adverse health effects among farm workers was associated with poor use of personal protective clothing and poor safety practices during pesticide use and handling. These data indicate the need for improved availability and use of protective equipment, and training in crop and pest management practices to prevent risky behavioursand for safer and sustainable vegetable production.

Published: September 2017

Aim: In radioiodine therapy (RIT) of benign thyroid-disorders empirical half-lives (HLemp) may be used to calculate therapeutic dose. In this study the effective half-life (HLf as well as potential influence factors were retrospectively determined in order to better estimate HLemp.Methods: Data from patients undergoing RIT from 01/09 to 04/14 were analysed (empirically estimated HLeff stratified by metabolic state and diagnosis). Inclusion criteria were: Benign thyroid-disorders, singular capsule administration and ≥ 6 dosimetry time-points (i. e. > 72 h inpatient stay). The effects of metabolic state, previous thy- reostatic medication and sex on HLeff were assessed by non-parametric ANOVA. The effects of target-volume and patient-age were assessed by regression analysis and nonparametric correlation (Spearman).Results: Data of 1,498 patients were analyzed: Graves’ Disease (GD), n = 286; multinodular goiter/disseminated autonomy (AMG/DA), n = 751; autonomous thyroid nodules (ATN), n = 421; euthyroid goiter (EG), n = 40. Mean HLeff (days ± SD) was 5.4 ± 1.5 in GD, 6.6 ± 1.2 in AMG/DA, 5.5 ± 1.6 in ATN and 6.9 ± 0.7 in EG. HLeff differed by metabolic state in GD, AMG/DA, and ATN, whereas neither thyreos- tatic medication nor sex were relevant. Moreover, target-volume (all diagnoses) and age (ATN and GD only) were associated with HLeft although the effect was small (R2 < 3.8%).Conclusion: When using standard HLeff for RIT, diagnosis and metabolic state should be considered for dose-calculations in RIT. Despite partial significance, the effects of target-volume and patient-age are small and a correction of HLeff, for these factors doesn’t appear to be necessary in a routine setting.

Purpose: We assessed patient discomfort and identified factors predictive of discomfort while receiving radioactive iodine (RAI) ablation.Methods: Between August 2015 and April 2016, 52 patients with differentiated thyroid cancer were enrolled in this study. All patients received recombinant human thyroid stimulating hormone (rhTSH) aided RAI ablation using 3.7 GBq or 5.55 GBq of RAI. Discomfort during their stay for RAI ablation was evaluated using a symptom questionnaire. We analyzed the relationship between the patient’s clinical data and the scores for the 15 items of the symptom questionnaire. We compared scores of questionnaires between male and female, under 45 years old and 45 and older, RAI activity of 3.7 GBq and 5.55 GBq. Also, scores of daily questionnaires were tested for differences.Results: Most patients did not have severe discomfort, but some patients had mild discomfort during their stay for RAI ablation, despite using rhTSH. Important determinants of discomfort were sex and age. Female patients reported more symptoms of fatigue, facial edema, cold intolerance, and nausea. Older patients (45 and older) complained of insomnia more often. However, the dose of RAI ablation (3.7 GBq vs 5.55 GBq) did not affect the scores of questionnaires.Conclusions: Sex and age were important predictors of patient’s discomfort during RAI ablation. Clinicians need to explain more about treatment and predicted discomforts to such patients before RAI ablation.

Authors: Larosa Claudio , Patra Niranjan , Salerno Marco , Mikac Lara , Merijs Meri Remo , Ivanda Mile
Published: September 2017

A polymer nanocomposite was produced by ultrasonic-assisted dispersion of multiwalled carbon nanotubes (MWCNTs) in a polycarbonate matrix using p-xylene and dichloromethane as the solvents. The filler loading was varied from 1 to 3 wt % in order to examine the effect of MWCNTs on the structure and properties of the composites. The nanocomposites were characterized by DSC, DTA, TGA, UV–vis, FTIR and Raman spectroscopy to evaluate the changes induced by the filler in the polymer matrix. UV–vis, FTIR and Raman spectroscopy measurements confirmed the presence of the dispersed phase in the composite films, while TGA and DSC analysis of the nanocomposites revealed enhanced thermal stability and decreased crystallinity, respectively, as compared to the neat polymer. The proposed composites can find application in a number of everyday products where polycarbonate is the base polymer.

Authors: Wang Hao , Chen Cui , Liu Weibing , Zhu Zhibo
Published: September 2017

We developed a direct vicinal difunctionalization of alkenes with iodine and TBHP at room temperature. This iodination and peroxidation in a one-pot synthesis produces 1-(tert-butylperoxy)-2-iodoethanes, which are inaccessible through conventional synthetic methods. This method generates multiple radical intermediates in situ and has excellent regioselectivity, a broad substrate scope and mild conditions. The iodine and peroxide groups of 1-(tert-butylperoxy)-2-iodoethanes have several potential applications and allow further chemical modifications, enabling the preparation of synthetically valuable molecules.

The approach to the cadastral value of the property is an indicator of the development of the real estate market, and therefore there are still divisions between countries preferring addictive this value from the surface and from values. The article comments on regulatory presented in selected European Union countries and presents original solution for the determination and correction of the cadastral value of the property, which is the basis to determine the property tax. About the tax character of this value, the fact that the introduction of social concern. Based on Poland, more than twenty years there has been discussion on this subject, but without regulation, there is only a discuss about the concepts of the system. The first attempts spatial analysis in order to determine the cadastral-tax areas have not yielded sufficient results, which is why the authors decided to present original solution resulting from the combination of statistical methods inclusive quantitative traits (facet surface) and qualitative characteristics (standard flat) with the characteristics of spatial (location, neighbourhood), in to determine the cadastral value of the property to eventually create the zones in cadastral-tax-zones. As an example, the property from the city Bochnia were used. The paper sought optimal zoning, to minimize variations and create homogeneous collections, which are enclosed areas, so that the weightings were small. To do this, the property housing was selected, as constituting the highest percentage of items on the market.

Authors: Mika Monika , Siejka Monika , Leń Przemysław
Published: September 2017

This article presents the results of analysis of the influence of selected economic, legal and environmental factors on the level of transaction prices of unbuilt land properties, in two randomly selected districts of the southern Poland. The results of the research allowed extraction of a group of factors influencing the spatial distribution of the average prices of the surveyed properties. They gave also the answer to the question about the extent to which the unit prices are confirmed by the state of properties management in the region. An analysis of the existing state in the selected region based on the analysis of the local market was performed. Furthermore, the conformity of local plans for the studied areas was examined, as well as an analysis of spatio-temporal distribution of transaction prices of real estate was performed. The research has shown that the level of transaction prices on the local real estate markets is related to the real estate management of the surveyed areas. The state of the economy is affected by many factors, most important of which seems to be the location in relation to urban areas and the condition of the access roads. The undertaken tests correspond with the directions of the world research.

Authors: Mrówczynska Maria , Sztubecki Jacek
Published: September 2017

This article attempts to analyse and predict vertical displacements of measurement-and- control network points located on civil structures founded on expansive soils, using artificial neural networks. Geodetic monitoring of civil structures consists in regular measurements of control point networks and interpretation of results. The obtained values of displacement provide sets of significant data which enable determination of the influence of changes in groundwater conditions of the subsoil on the deformation processes occurring in structures founded on it. Using such data sets, it is possible to draw conclusions regarding the dynamics of the occurrence of deformation and to develop a geometric model of displacements. In recent years, methods of prediction based on artificial intelligence have been increasingly prominent. Neural networks and evolutionary algorithms, which can supplement each other, make advanced tools applied in the process of prediction of deformations. In order to forecast displacements of control points, demonstrating changes in a civil structure, multi-layer artificial neural networks are employed in this article, taught using the method of error backpropagation and gradient optimization methods. The analysed results in the form of height differences were obtained through a series of measurements on a civil structure, taken by means of precise levelling at monthly intervals.

Published: September 2017

The aim of this study is to describe uncertainty of the Global Rural-Urban Mapping Project (GRUMP) data based on Polish population reference grid created by the Central Statistical Office of Poland, using INSPIRE grid coding system. The adopted population data uncertainty analysis methodology combined three different approaches, i.e. simple change detection algorithm to obtain discrepancies at the grid cell level, statistical analytical approach to investigate these discrepancies’ frequency distribution, and GIS approach to analyse spatial pattern of distinguished population difference classes. The results showed significant differences in population count at the grid cell level. The maximum magnitude of GRUMP vs. Polish Reference Grid overestimation equals 4087 people per 1 sq. km, while the underestimation equals 20,086 people per 1 sq. km. Very few grid cell shows no difference in population count, i.e. 1.5% of total grid cell count. GRUMP data overestimates Polish total population by 0.15%, while it underestimates the average population density by 50%. The highest population underestimations were identified in the centers of the cities, while suburban areas were characterised by the large and regular population overestimations within GRUMP dataset. These GRUMP dataset imperfections can be attributed to country-specific administrative divisions and to the varying effectiveness of the urban centers delimitation mapping using the night sky light intensity, including blooming effects as well as not frequently illuminated small settlements.

Published: September 2017

Tree models and information on the various characteristics of trees and forests are required for forest management, city models, carbon accounting and the management of assets. In order to get precise characteristics and information, tree modelling must be done at individual tree level as it represents the interaction process between trees. For sustainable forest management, more information is needed, however, the traditional methods of investigating forest parameters such as, tree height, diameter at breast height, crown diameter, stem curve and stem mapping or tree location are complex and labour-intensive. Light detection and ranging (LiDAR) has been proposed as a suitable technique for mapping of forest biomass. LiDAR can be operated in airborne configuration (Airborne laser scanning) or in a terrestrial setup. Terrestrial Laser Scanner measures forests from below canopy and offers a much more detailed description of the individual trees. The aim of this study is to derive the essential tree parameters for estimation of biomass from terrestrial LiDAR data. Tree height, diameter at breast height, crown diameter, stem curve and tree locations were extracted from Terrestrial Laser Scanner point clouds.
Right-of-way for Transmission Facilities as Regulation
of Legal Relationships Regarding Real Estate between
the Real Estate Owner and the Transmission Entity
Authors: Przewiezlikowska Anna
Published: September 2017

In Poland, after World War II, most of the technical infrastructure was built based on a construction permit,
and without a legal title to a given real property. Therefore, a necessity arose for the regulation of property rights
where technical infrastructure was built. For the establishment of the right-of-way for transmission facilities it is essential
to regulate the legal relationships between the owner of the real estate and the transmission entity and their entry
into the land and mortgage register. The extent of the granted right-of-way determines the value of consideration
for the owner of the encumbered property.
This study analyzes the rules for the determination, establishment and surveying preparation of the right-of-way for
various types of transmission facilities. First a thorough examination of the legal status of the real property was required
and then the extent of the necessary right-of-way to be established for the given facilities was analyzed. The
next stage of the study involved determining the extent of the rights-of-way and appropriate protective zones for the
networks pursuant to the relevant technical guidelines. The analysis revealed significant diversity of legal regulations
on the establishment of the right-of-way for the specific types of public utilities.
Methodology of Inventory the Real Estate Components for the Purpose
of Their Valuation Due to Road Construction – Case Study in Krakow
Authors: Siejka Monika , Mika Monika
Published: September 2017

The development of the communication systems determines the economic level of the country. In Poland,
despite the successive investments in this area, it is still not enough beneficial solutions to the road network and
international calls. The problem of the acquisition of property for public roads on both the valuation principles and the
way of obtaining land for these purposes is constantly modified. These changes are intended to simplify the
procedures, which have a significant impact on shortening of the investment process. The current provisions of law
give the possibility of the start of road investment before a property owner receives compensation for land taken for
this purpose. This situation requires an inventory of component parts of the property for the purposes of their
valuation. The paper presents the methodology of inventory the real estate components for the needs of their valuation
using modern measurement techniques GNSS and GIS.

The Near-Earth Object
Wide-field Infrared Survey Explorer (NEOWISE) reactivation mission has completed its third year of surveying the sky in the thermal infrared for near-Earth asteroids and comets. NEOWISE collects simultaneous observations at 3.4 and 4.6 μm of solar system objects passing through its field of regard. These data allow for the determination of total thermal emission from bodies in the inner solar system, and thus the sizes of these objects. In this paper, we present thermal model fits of asteroid diameters for 170 NEOs and 6110 Main Belt asteroids (MBAs) detected during the third year of the survey, as well as the associated optical geometric albedos. We compare our results with previous thermal model results from NEOWISE for overlapping sample sets, as well as diameters determined through other independent methods, and find that our diameter measurements for NEOs agree to within 26% (1σ) of previously measured values. Diameters for the MBAs are within 17% (1σ). This brings the total number of unique near-Earth objects characterized by the NEOWISE survey to 541, surpassing the number observed during the fully cryogenic mission in 2010.
Evidence for Field-parallel Electron Acceleration in Solar Flares
Authors: Haerendel G.
Published: September 2017

It is proposed that the coincidence of higher brightness and upward electric current observed by Janvier et al. during a flare indicates electron acceleration by field-parallel potential drops sustained by extremely strong field-aligned currents of the order of 104 A m−2. A consequence of this is the concentration of the currents in sheets with widths of the order of 1 m. The high current density suggests that the field-parallel potential drops are maintained by current-driven anomalous resistivity. The origin of these currents remains a strong challenge for theorists.
Red Supergiants as Cosmic Abundance Probes: Massive Star Clusters in M83 and the Mass–Metallicity Relation of Nearby Galaxies

Published: September 2017

We present an abundance analysis of seven super star clusters in the disk of M83. The near-infrared spectra of these clusters are dominated by red supergiants, and the spectral similarity in the J-band of such stars at uniform metallicity means that the integrated light from the clusters may be analyzed using the same tools as those applied to single stars. Using data from VLT/KMOS, we estimate metallicities for each cluster in the sample. We find that the abundance gradient in the inner regions of M83 is flat, with a central metallicity of

relative to a solar value of Z
⊙ = 0.014, which is in excellent agreement with the results from an analysis of luminous hot stars in the same regions. Compiling this latest study with our other recent work, we construct a mass–metallicity relation for nearby galaxies based entirely on the analysis of RSGs. We find excellent agreement with the other stellar-based technique—that of blue supergiants—as well as with temperature-sensitive (“auroral” or “direct”) H ii-region studies. Of all the H ii-region strong-line calibrations, those that are empirically calibrated to direct-method studies (N2 and O3N2) provide the most consistent results.

The

state of the hydrogen molecule has the second largest triplet-state excitation cross-section, and plays an important role in the heating of the upper thermospheres of outer planets by electron excitation. Precise energies of the H2, D2, and HD

(

) levels are calculated from highly accurate ab initio potential energy curves that include relativistic, radiative, and empirical non-adiabatic corrections. The emission yields are determined from predissociation rates and refined radiative transition probabilities. The excitation function and excitation cross-section of the

state are extracted from previous theoretical calculations and experimental measurements. The emission cross-section is determined from the calculated emission yield and the extracted excitation cross-section. The kinetic energy (E

k
) distributions of H atoms produced via the predissociation of the

state, the

dissociative emission by the magnetic dipole and electric quadrupole, and the

cascade dissociative emission by the electric dipole are obtained. The predissociation of the

k
of ∼1.0 and ∼0.8 eV/atom, respectively. The

The LIGO/Virgo Collaboration (LVC) detected on 2017 January 4 a significant gravitational-wave (GW) event (now named GW170104). We report in this Letter the main results obtained from the analysis of hard X-ray and gamma-ray data of the AGILE mission that repeatedly observed the GW170104 localization region (LR). At the LVC detection time T
0 AGILE observed about 36% of the LR. The gamma-ray imaging detector did not reveal any significant emission in the energy range 50 MeV–30 GeV. Furthermore, no significant gamma-ray transients were detected in the LR that was repeatedly exposed over timescales of minutes, hours, and days. We also searched for transient emission using data near T
0 of the omnidirectional detector MCAL operating in the energy band 0.4–100 MeV. A refined analysis of MCAL data shows the existence of a weak event (that we call “E2”) with a signal-to-noise ratio of 4.4σ lasting about 32 ms and occurring 0.46 ± 0.05 s before T
0. A study of the MCAL background and of the false-alarm rate of E2 leads to the determination of a post-trial significance between 2.4σ and 2.7σ for a temporal coincidence with GW170104. We note that E2 has characteristics similar to those detected from the weak precursor of GRB 090510. The candidate event E2 is worth consideration for simultaneous detection by other satellites. If associated with GW170104, it shows emission in the MeV band of a short burst preceding the final coalescence by 0.46 s and involving ∼10−7 of the total rest mass energy of the system.
A Comet Active Beyond the Crystallization Zone
Authors: Jewitt David , Hui Man-To , Mutchler Max , Weaver Harold , Li Jing , Agarwal Jessica
Published: September 2017

We present observations showing inbound long-period comet C/2017 K2 (PANSTARRS) to be active at a record heliocentric distance. Nucleus temperatures are too low (60–70 K) either for water ice to sublimate or for amorphous ice to crystallize, requiring another source for the observed activity. Using the Hubble Space Telescope we find a sharply bounded, circularly symmetric dust coma 105 km in radius, with a total scattering cross-section of ∼105 km2. The coma has a logarithmic surface brightness gradient −1 over much of its surface, indicating sustained, steady-state dust production. A lack of clear evidence for the action of solar radiation pressure suggests that the dust particles are large, with a mean size ≳0.1 mm. Using a coma convolution model, we find a limit to the apparent magnitude of the nucleus

(absolute magnitude

). With assumed geometric albedo p

V
 = 0.04, the limit to the nucleus circular equivalent radius is <9 km. Prediscovery observations from 2013 show that the comet was also active at 23.7 au heliocentric distance. While neither water ice sublimation nor exothermic crystallization can account for the observed distant activity, the measured properties are consistent with activity driven by sublimating supervolatile ices such as CO2, CO, O2, and N2. Survival of supervolatiles at the nucleus surface is likely a result of the comet’s recent arrival from the frigid Oort Cloud.

The Natural History Museum, London (NHMUK) has embarked on an ambitious programme to digitise its collections. The first phase of this programme was to undertake a series of pilot projects to develop the workflows and infrastructure needed to support mass digitisation of very large scientific collections. This paper presents the results of one of the pilot projects – iCollections. This project digitised all the lepidopteran specimens usually considered as butterflies, 181,545 specimens representing 89 species from the British Isles and Ireland. The data digitised includes, species name, georeferenced location, collector and collection date - the what, where, who and when of specimen data. In addition, a digital image of each specimen was taken. A previous paper explained the way the data were obtained and the background to the collections that made up the project. The present paper describes the technical, logistical, and economic aspects of managing the project.
La mise en place d’un marché funéraire du cercueil à Paris au xix e siècle
Authors: Sauget Stéphanie
Published: September 2017

À Paris, dès 1801, le cercueil devient un accessoire désormais obligatoire pour tous les Parisiens décédés dans la ville. Il doit être personnel et à usage unique. Cette nouvelle obligation, à visée égalitaire et sanitaire, entraîne une révolution du cercueil à la fois qualitative et quantitative. Aux côtés des cercueils gratuits fournis par la préfecture de la Seine aux indigents, apparaissent de nouveaux cercueils payants produits en masse et de plus en plus standardisés. Cet article explore les principales transformations à l’œuvre et étudie en particulier la mise en place d’un marché funéraire du cercueil très encadré, à partir des archives des entreprises privées des Pompes funèbres.
Stratégies des jeunes dans une économie de plantation de l’Ouest ivoirien
Authors: Balac Ronan
Published: September 2017

L’article traite des jeunes planteurs de café-cacao du village de Zopaguhé dans l’Ouest ivoirien. La jeunesse y est examinée comme le point de fragilité, mais aussi d’innovation, du système agricole d’exportation, qui, s’il a su prodiguer enrichissement et ascension sociale aux générations précédentes, n’offre plus aujourd’hui les conditions de l’autonomisation et de l’émancipation. Cette recherche montre comment ces jeunes, scolarisés, ouverts sur le monde, mobilisent leur épargne agricole en vue de s’investir « entrepreneur individuel » hors du village, tout en développant des solidarités inédites qui transcendent les oppositions anciennes. L’étude signale la complexification de la société rurale et les risques d’apparition de nouveaux clivages dans le contexte d’une concurrence libérale exacerbée.
Entre loyalisme, accommodements et résistance, les industriels alsaciens à l’épreuve de l’économie de guerre
Authors: Vonau Pierre
Published: September 2017

Dès août 1914, les industriels alsaciens sont confrontés à la problématique du loyalisme. Certains rejoignent la France ou la Suisse. Ceux qui restent subissent bon gré mal gré les rigueurs de l’économie de guerre allemande, aggravées en Alsace pour des raisons stratégiques et politiques. Pour assurer la survie de leurs entreprises, ils mènent des stratégies d’accommodements qui évoluent en résistance individuelle et collective. Ils prennent conscience que la victoire française présenterait moins de risques que celle de l’Allemagne.
La gestion de la main-d’œuvre ouvrière durant la Première Guerre mondiale, la pratique d’une entreprise française moyenne en région stéphanoise
Authors: Vernet Antoine
Published: September 2017

La mobilisation industrielle se traduit lors de la Grande Guerre par la mise en place d’une économie dirigée. Les conditions d’existence des entreprises évoluent en conséquence, notamment en ce qui concerne la main-d’œuvre ouvrière. L’étude des archives de la société Chavanne-Brun à Saint-Chamond (Loire) permet d’aborder les mutations de la gestion du personnel. Des efforts d’organisation et de rationalisation facilitent l’adaptation de la production aux nécessités du temps. De nouvelles procédures bureaucratiques modifient les méthodes de recrutement de la main-d’œuvre. Enfin, la politique sociale de l’entreprise s’amplifie de manière à fixer et mieux contrôler un personnel renouvelé.
Les Cent-Jours : un second Empire ?
Authors: Boudon Jacques-Olivier
Published: September 2017

Avant la restauration de l’Empire en 1852, il y eut un précédent, puisqu’en revenant de l’île d’Elbe en 1815, Napoléon avait déjà restauré une première fois l’empire. Pourtant à aucun moment le terme de « second empire » n’a été employé pour désigner cette nouvelle phase politique. Napoléon a en effet recherché la continuité malgré le retour à l’esprit de 1789 et la rédaction d’une nouvelle constitution et s’est appuyé sur le principe de légitimité pour justifier son retour au pouvoir. Pourtant c’est bien un nouvel empire, avec de nouvelles institutions qu’il propose et qu’il lègue à son fils, en abdiquant, faisant de Napoléon II, empereur virtuel du 22 juin au 8 juillet 1815, le relais indispensable dans la continuité dynastique conduisant à Napoléon III.
Louis de Bonald et la question du divorce, de la rédaction du Code civil à la loi du 8 mai 1816
Authors: Bertran de Balanda Flavien
Published: September 2017

Louis de Bonald (1754-1840) ne fut pas qu’un théoricien contre-révolutionnaire, père d’une métaphysique sociale. Député de l’Aveyron sous la Restauration et chef spirituel des ultras, son nom reste attaché à la loi du 8 mai 1816 abolissant le divorce. Cette date marque l’aboutissement d’un combat auquel il s’était voué dès le projet de rédaction du Code civil, avec la publication de son fameux Divorce considéré au xix e siècle (1801), mais également d’autres textes moins connus, telle sa Lettre à Portalis ou encore divers articles de presse non repris, dont l’étude suggère des lumières nouvelles sur la question. À l’image d’une attitude inflexible servant un propos liberticide, se substitue en effet celle d’un homme conscient des enjeux de son temps, et souhaitant que la régénération postrévolutionnaire ne se réalise pas au détriment des plus faibles, en l’occurrence la femme et l’enfant.
Prévention des risques organisationnels en ambulatoire : une étude comparative de 4 cliniques
Authors: Bruyère Christelle , Massard Nelly , Romeyer Cécile
Published: September 2017

« Les séjours hospitaliers doivent être moins fréquents et moins longs. C’est pourquoi je veux doubler le rythme de croissance de la chirurgie ambulatoire » , indique Marisol Touraine – ministre des Affaires sociales, de la Santé et des Droits des femmes – qui fixe l’objectif dès 2016 d’une opération sur deux réalisée en ambulatoire. La chirurgie ambulatoire tend à devenir la norme. Or, la chirurgie ambulatoire est un changement culturel profond et un processus organisationnel complexe invitant à repenser les modes d’accès aux soins et de gouvernance. Dans cette perspective, des travaux initiés par l’ANAP (Agence nationale d’appui à la performance des établissements de santé et médico-sociaux) et l’HAS (Haute autorité de santé) publiés en 2013 visent à guider les acteurs de terrain dans le développement des pratiques ambulatoires, en préconisant une approche Lean comme système organisationnel global. Quel usage en ont les acteurs ? Quelle perception ont-ils du Lean Management  ? Et comment se prémunissent-ils des risques organisationnels du Lean dans un contexte de chirurgie ambulatoire ? Une étude comparative de 4 centres autonomes ambulatoires (4 cliniques privées, seuls centres autonomes à ce jour en France) a permis de mettre en avant les principaux risques perçus par les acteurs – mise en tension et rigidification du travail- ainsi que les moyens techniques, organisationnels et humains pour faire face. Il ressort que les cliniques étudiées ont su se préserver des marges de manœuvre pour adapter le flux aux pressions, préservant ainsi le slack organisationnel nécessaire à la cohabitation d’un standard organisationnel et d’une relation unique.
Procédure d’élimination des dossiers médicaux
Authors: Leroy A. , Schoenzetter-Laute J. , Riou C.
Published: September 2017

Les durées de conservation des dossiers médicaux ont été redéfinies dans le code de santé publique modifié par le décret 2006-6. Les établissements de santé confrontés à l’obligation d’optimiser la gestion de leurs espaces de stockage ont dû s’y adapter. Les auteurs présentent dans cet article la procédure en cours dans leur établissement. Les dossiers médicaux sont gérés par spécialité aux Archives centrales ou chez un hébergeur agréé. Leur élimination annuelle est précédée d’une réactualisation de l’ensemble du dossier. Des durées de conservation plus longues sont définies pour des pathologies particulières. Un échantillonnage est effectué pour conservation historique. En 2015, 12 800 dossiers gérés en centralisé ont été détruits soit 233 mètres linéaires. Ceci représente 57 % du potentiel destructible, 20 % des dossiers sont réactualisés et 22 % des dossiers sont conservés plus longtemps. Néanmoins la place libérée ne permet pas d’assurer l’accroissement linéaire annuel. La réactualisation des dossiers multi-spécialités ou externalisés et la gestion des cas particuliers (donneurs décédés, accouchements sous X, dossiers de génétique) induisent des coûts supplémentaires pouvant constituer un frein à l’élimination. La destruction des dossiers informatisés sera à prévoir. Les éditeurs n’ont pas inclus pour le moment le cycle de vie complet du dossier. Il est à noter que le patient dispose d’un droit à l’oubli au-delà des durées légales de conservation.
