Education for Technology Transition Restructures Energy Systems
Authors: Ahamer Gilbert
Published: October 2018

Our present world calls for peaceful transitions, given the ruptures in political cultures and the massive global threat of climate change. A transition of the energy system will and must go hand in hand with a socio-political transition. Any design of learning procedures should hence take into account real-world projects, including projects on environment, climate change and energy. This chapter suggests that diverse patterns, lenses and metrics are taken into account when educating. Such an interparadigmatic approach means to focus on multiple perceptions from diverse stakeholders. Learners should be able to bridge different viewpoints by their capacity to integrate diverse values, perspectives, and views. As a concrete case study, the cooperative negotiation game “Surfing Global Change” is used to show how these educational values can be implemented. Further analyses of literature and data on didactics, climate change and economic transitions complement this chapter.

Published: October 2018

The theoretical study of laminar boundary layer flows of a non-Newtonian fluid past a stretching sheet in an embedded porous medium in the presence of suction/injection is of significant importance in the crystal growing, geothermal, metallurgical, polymer extrusion and several other technological processes. Casson fluid model is one such fluid model used to characterize the behaviour of non-Newtonian fluids. The present article discusses the Casson fluid flow past a permeable stretching sheet in the presence of mass transpiration. The physical problem is modelled into a system of nonlinear partial differential equations which are analytically solved by transforming them into nonlinear ordinary differential equations with constant coefficient by means of similarity transformations. The analysis reveals the effect of Casson parameter on the velocity boundary. In fact, the increasing Casson parameter results in the suppression of velocity boundary. It is found that the skin friction coefficient decreases with the decreasing values of Casson parameter. The effects of Darcy drag force and the mass transpiration are also analyzed by means of various plots.

For the first time the influence of pressure of chitosan solutions in carbonic acid on the adsorption of chitosan onto a collagen tissue of biological heart-valve prostheses and on the structure of the resulting biocomposite was studied. It turned out that the dependence of an amount of the chitosan adsorbed onto the collagen tissue has bell-shaped form reaching a maximum adsorption of about 0.8 weight. % at 30-40 MPa and then falling to 0.3 wt. % with further pressure increase up to 50 MPa. It was found that this treatment leads to a significant change of the morphology of the tissue surface which depends on the pressure in the system. It was also revealed that under pressure growth collagen fibrils are compacted in the tissue bulk which leads to the extrusion of the polymer embedded in the collagen matrix.

Published: October 2018

Differential scanning calorimetry was used to study the temperatures and character of phase transitions of fibers based on polyether ether ketones. It is shown that in the production of fine fibers from polyether ether ketones, a predominantly amorphous structure is formed. Increasing the temperature to the crystallization temperature leads to an almost twofold increase in the degree of crystallinity. Lower molecular weight polyether ether ketone is characterized by a higher rate of crystallization and the formation of a more homogeneous crystalline structure.

Almsgiving as a rhetorical device in 4QTobit?
Authors: Evans Annette H.
Published: October 2018

This article is a sequel to an earlier exploration of the possibility of a shift in the Book of Tobit from the Deuteronomistic theological perspective in the beginning to a more nuanced concept of theodicy in the end. The Semitic versions of Tobit found at Qumran are regarded as the earliest witnesses to the story of Tobit, dating from ca. 100 BCE to the early part of the 1st century CE. They are very fragmentary, but the theme of almsgiving recurs at regular intervals in the narrative. In the beginning the Deuteronomistic theological perspective is expressed in terms of Tobit’s belief that God will reward with prosperity those who give alms to their own kinsmen, but towards the end the ideology appears to shift from the rather self-centred ‘prosperity cult’ orientation to a different motivation for almsgiving. The aim of this article is to test the possibility that the almsgiving references are rhetorical hinges that mark the movement of the narrative into a different ideological viewpoint. The complexity of the manuscript transmission of the story of Tobit in the larger matrix of diachronic cultural and religious trends in the ancient Near East is kept in mind when text-critical problems are encountered.

Measured particle water uptake enhanced by co-condensing vapours
Authors: Hu Dawei , Topping David , McFiggans Gordon
Published: October 2018

Abstract. Co-condensation of inorganic or organic vapours on growing droplets could significantly enhance both cloud condensation nucleus (CCN) and cloud droplet number concentration, thereby influencing cloud albedo and climate. Until now, there has been very few direct observational evidence of this process. We have measured the growth of inorganic salt particles exposed to both water and organic vapours at 291.15 K in the laboratory, showing that co-condensation of the organic vapours significantly enhances water uptake of aerosols. After exposure to water and propylene glycol vapours, ammonium sulfate particles grew much more than any previously measured particles, inorganic or organic, at the same relative humidity (RH). The maximum equivalent hygroscopicity parameter, κ, was observed to reach up to 2.64, very much higher than values (0.1 < κ < 0.9) measured for atmospheric particulate matter using conventional instrumentation, which may be blind to this effect. Under a continuously replenishing organic vapour field, the particles never reached equilibrium owing to the presence of the involatile solute and were observed to continuously grow with increasing exposure time, in agreement with model simulations. Co-condensation of butylene glycol (which has similar volatility but, at aw  =  0.9, a higher Sorg than propylene glycol in our system) and tri-ethylene glycol (which has lower volatility and, at aw  =  0.9, lower Sorg than propylene glycol in our system) vapours was additionally measured in this study. The maximum equivalent hygroscopicity parameter, κ, reached as high as 8.48 for ammonium sulfate particles exposed to water and tri-ethylene glycol vapours at 90 % RH. This enhancement of particle water uptake through co-condensation of vapours constitutes the direct measurement of this process, which may substantially influence cloud droplet formation in the atmosphere. In addition, the model simulations for exposure to co-condensing butylene glycol and tri-ethylene glycol vapours with water show that there are factors other than Sorg which influence the co-condensation of semi-volatile organic compounds (SVOCs) that are as yet not understood.

Abstract. During the ACRIDICON-CHUVA field project
(September–October 2014; based in Manaus, Brazil) aircraft-based in situ
measurements of aerosol chemical composition were conducted in the tropical
troposphere over the Amazon using the High Altitude and Long Range Research
Aircraft (HALO), covering altitudes from the boundary layer (BL) height up to
14.4 km. The submicron non-refractory aerosol was characterized by
flash-vaporization/electron impact-ionization aerosol particle mass
spectrometry. The results show that significant secondary organic aerosol
(SOA) formation by isoprene oxidation products occurs in the upper
troposphere (UT), leading to increased organic aerosol mass concentrations
above 10 km altitude. The median organic mass concentrations in the
UT above 10 km range between 1.0 and
2.5 µg m−3 (referring to standard temperature and pressure;
STP) with interquartile ranges of 0.6 to 3.2 µg m−3 (STP),
representing 78 % of the total submicron non-refractory aerosol particle
mass. The presence of isoprene-epoxydiol-derived secondary organic aerosol
(IEPOX-SOA) was confirmed by marker peaks in the mass spectra. We estimate
the contribution of IEPOX-SOA to the total organic aerosol in the UT to be about
20 %. After isoprene emission from vegetation, oxidation processes occur
at low altitudes and/or during transport to higher altitudes, which may lead
to the formation of IEPOX (one oxidation product of isoprene). Reactive
uptake or condensation of IEPOX on preexisting particles leads to IEPOX-SOA
formation and subsequently increasing organic mass in the UT.
This organic mass increase was accompanied by an increase in the nitrate mass
concentrations, most likely due to NOx production by
lightning. Analysis of the ion ratio of NO+ to NO2+
indicated that nitrate in the UT exists mainly in the form of
organic nitrate. IEPOX-SOA and organic nitrates are coincident with each
other, indicating that IEPOX-SOA forms in the UT either on
acidic nitrate particles forming organic nitrates derived from IEPOX or on
already neutralized organic nitrate aerosol particles.
Understanding of atmospheric aerosol particles with improved
particle identification and quantification by single particle mass
spectrometry

Published: October 2018

Abstract. Single particle mass spectrometry (SPMS) is a useful, albeit not fully quantitative tool to determine chemical composition and mixing state of aerosol particles in the atmosphere. During a six-week field campaign in summer 2016 at a rural site in the upper Rhine valley near Karlsruhe city in southwest Germany, ~3.7 x 105 single particles were analyzed by a laser ablation aerosol particle time-of-flight mass spectrometer (LAAPTOF). Combining fuzzy classification, marker peaks, typical peak ratios, and laboratory-based reference spectra, seven major particle classes were identified. With the precise identification and well characterized overall detection efficiency (ODE) for this instrument, particle similarity can be transferred into corrected number fractions and further transferred into mass fractions. Considering the entire measurement period, Potassium rich and aromatics coated dust (class 5) dominated the particle number (46.5 % number fraction) and mass (36.0 % mass fraction); Sodium salts like particles (class 3) were the second lowest in number (3.5 %), but the second dominating class in terms of particle mass (25.3 %). This difference demonstrates the crucial role of particle mass quantification for SPMS data. Using corrections for maximum, mean, and minimum ODE, the total mass of the quantified particles measured by LAAPTOF accounts for ~12 %, ~25 %, and ~104 % of the total mass measured by an aerosol mass spectrometer (AMS) with a collection efficiency of 0.5. These two mass spectrometers show a good correlation (correlation coefficient γ > 0.6) regarding total mass for more than 70 % of the measurement time, indicating non-refractory species measured by AMS might originate from particles consisting of internally mixed non-refractory and refractory components. In addition, specific relationships of LAAPTOF ion intensities and AMS mass concentrations for non-refractory compounds were found for specific measurement periods. Furthermore, our approach allows for the first time to assign the non-refractory compounds measured by AMS to different particle classes. Overall AMS-nitrate was mainly arising from class 3, while class 5 was dominant during events rich in organic aerosol particles.
Nitrogen and oxygen availabilities control water column nitrous oxide production during seasonal anoxia in the Chesapeake Bay
Authors: Ji Qixing , Frey Claudia , Sun Xin , Jackson Melanie , Lee Yea-Shine , Jayakumar Amal , Cornwell Jeffrey C. , Ward Bess B.
Published: October 2018

Abstract. Nitrous oxide (N2O) is a greenhouse gas and an ozone
depletion agent. Estuaries that are subject to seasonal anoxia are generally
regarded as N2O sources. However, insufficient understanding of the
environmental controls on N2O production results in large uncertainty
about the estuarine contribution to the global N2O budget. Incubation
experiments with nitrogen stable isotope tracer were used to investigate the
geochemical factors controlling N2O production from denitrification in
the Chesapeake Bay, the largest estuary in North America. The highest
potential rates of water column N2O production via denitrification
(7.5±1.2 nmol-N L−1 h−1) were detected during summer
anoxia, during which oxidized nitrogen species (nitrate and nitrite) were
absent from the water column. At the top of the anoxic layer, N2O
production from denitrification was stimulated by addition of nitrate and
nitrite. The relative contribution of nitrate and nitrite to N2O
production was positively correlated with the ratio of nitrate to nitrite
concentrations. Increased oxygen availability, up to 7 µmol L−1
oxygen, inhibited both N2O production and the reduction of nitrate to
nitrite. In spring, high oxygen and low abundance of denitrifying microbes
resulted in undetectable N2O production from denitrification. Thus,
decreasing the nitrogen input into the Chesapeake Bay has two potential
impacts on the N2O production: a lower availability of nitrogen
substrates may mitigate short-term N2O emissions during summer
anoxia; and, in the long-run (timescale of years), eutrophication will be alleviated
and subsequent reoxygenation of the bay will further inhibit N2O
production.
EcoGEnIE 1.0: plankton ecology in the cGEnIE Earth system model
Authors: Ward Ben A. , Wilson Jamie D. , Death Ros M. , Monteiro Fanny M. , Yool Andrew , Ridgwell Andy
Published: October 2018

Abstract. We present an extension to the carbon-centric Grid Enabled Integrated Earth
system model (cGEnIE) that explicitly accounts for the growth and
interaction of an arbitrary number of plankton species. The new package
(ECOGEM) replaces the implicit, flux-based parameterisation of the
plankton community currently employed, with explicitly resolved plankton
populations and ecological dynamics. In ECOGEM, any number of plankton
species, with ecophysiological traits (e.g. growth and grazing rates)
assigned according to organism size and functional group (e.g. phytoplankton
and zooplankton) can be incorporated at runtime. We illustrate the
capability of the marine ecology enabled Earth system model
(EcoGEnIE) by comparing results from one configuration of ECOGEM (with eight generic
phytoplankton and zooplankton size classes) to climatological and seasonal
observations. We find that the new ecological components of the model show
reasonable agreement with both global-scale climatological and local-scale
seasonal data. We also compare EcoGEnIE results to the existing
biogeochemical incarnation of cGEnIE. We find that the resulting global-scale
distributions of phosphate, iron, dissolved inorganic carbon, alkalinity, and
oxygen are similar for both iterations of the model. A slight deterioration
in some fields in EcoGEnIE (relative to the data) is observed, although we
make no attempt to re-tune the overall marine cycling of carbon and nutrients
here. The increased capabilities of EcoGEnIE in this regard will enable
future exploration of the ecological community on much longer timescales than
have previously been examined in global ocean ecosystem models and
particularly for past climates and global biogeochemical cycles.
Global downscaling of remotely sensed soil moisture using neural networks
Authors: Alemohammad Seyed Hamed , Kolassa Jana , Prigent Catherine , Aires Filipe , Gentine Pierre
Published: October 2018

Abstract. Characterizing soil moisture at spatiotemporal scales relevant to land surface processes (i.e.,
of the order of 1 km) is necessary in order to quantify its role in regional
feedbacks between the land surface and the atmospheric boundary layer.
Moreover, several applications such as agricultural management can benefit
from soil moisture information at fine spatial scales. Soil moisture
estimates from current satellite missions have a reasonably good temporal
revisit over the globe (2–3-day repeat time); however, their finest spatial
resolution is 9 km. NASA's Soil Moisture Active Passive (SMAP) satellite has
estimated soil moisture at two different spatial scales of 36 and 9 km since
April 2015. In this study, we develop a neural-network-based downscaling
algorithm using SMAP observations and disaggregate soil moisture to 2.25 km
spatial resolution. Our approach uses the mean monthly Normalized Differenced
Vegetation Index (NDVI) as ancillary data to quantify the subpixel
heterogeneity of soil moisture. Evaluation of the downscaled soil moisture
estimates against in situ observations shows that their accuracy is better
than or equal to the SMAP 9 km soil moisture estimates.
How density, diversity, land use and neighborhood type influences bus mobility in the Swedish city of Karlstad: Mixing spatial analytic and typo-morphological approaches to assess the indirect effect of urban form on travel
Authors: Stojanovski Todor
Published: October 2018

In the research on the effect of urban form on travel, a set of D-variables (density, diversity, design, destination accessibility, etc.) describes land use. Typo-morphology studies the historical emergence and evolution of urban patterns and their elements. In the typo-morphological approach, land use is an underlying element of neighborhood type. Neighborhood type defines urban areas that are relatively similar according to a range of attributes, such as building types, lot sizes, street layouts and land uses. This paper juxtaposes these two approaches to investigate the effect of density and diversity, land use and neighborhood type on bus mobility in the Swedish city of Karlstad. The results show that the number of residents and jobs in standard 400-meter walksheds around bus stops explains a third of the variation in bus ridership, which corresponds to previous studies in Sweden. The scatter plots with neighborhood types indicate that bus patronage variables and the D-variables cluster in intervals. This information about ranges and maximums in bus patronage in different neighborhood types is particularly important for urban designers and planners who work with typologies, form-based codes (FBCs) or transit-oriented development (TOD).

En última instancia, se aspira a contribuir modestamente a la mejora de la regulación de la actividad delimitadora del objeto de la controversia y, por ende, al perfeccionamiento de esta útil herramienta que presta un servicio significativo a la calidad de la justicia civil.
Regímenes de provisión de vivienda y emancipación residencial: análisis del esfuerzo público en vivienda en España y efecto en las oportunidades de emancipación desde una perspectiva autonómica comparada
Authors: Echaves García Antonio , Navarro Yañez Clemente Jesús
Published: October 2018

Los regímenes de provisión de vivienda pueden definirse como el conjunto de iniciativas (públicas y privadas) que configuran las opciones disponibles en cada sociedad para conseguir un lugar en el que residir. Desde esta perspectiva cabe considerarlos como un elemento central de los regímenes o Estados de bienestar, junto con las políticas de empleo, sanidad o educación. De hecho, análisis comparativos entre países muestran la existencia de distintos regímenes de provisión de vivienda que, por un lado, se corresponden con clasificaciones existentes de regímenes de bienestar y, por otro lado, tienen efectos sobre las condiciones de acceso a la vivienda y el régimen de tenencia predominante. En estos estudios España suele calificarse como un modelo dualista, que fomenta la vivienda en propiedad sobre la de alquiler; frente al modelo integrado, más característico de algunos países del centro y del norte de Europa. En este marco, el presente trabajo pretende desarrollar dos objetivos. Por un lado, mostrar la existencia de sistemas autonómicos de provisión de vivienda en España, y proponer indicadores al respecto. Por otro lado pretende mostrar, como caso, sus efectos sobre la emancipación residencial de los jóvenes, utilizando para ello datos procedentes de diferentes fuentes (Censo de Población y Vivienda, EPA y otras fuentes de datos secundarias españolas). Con ello se pretende realizar propuestas analíticas y empíricas sobre un aspecto aún poco estudiado de los sistemas subnacionales de bienestar.

Power and Ideology Revealed in The Awig-awig (Customary Law) Text of Tenganan Pegringsingan Village: Critical Ecolinguistic Study
Authors: Astawa I Gede , Budiarsa Made , Simpen I Wayan
Published: October 2018

Awig-awig ‘customary law’ is a written rule which is used to manage customary village organization in Bali. This customary law has a very important role in maintaining the environment in terms of natural environment (palemahan), social environment (pawongan), and spiritual environment (parhyangan).   Therefore, every awig-awig made should be based on Tri Hita Karana (THK) concept. The THK is defined as ‘three causes of happiness and prosperity’. In this study, THK is considered as an ecosophy used to judge the existence of lexical items, grammatical contructs, and other linguistic features used in the awig-awig text. In critical discourse, the exisistence of any texts is considered to bring underlying power and ideology. Thus, the written text of the awig-awig belongs to Tenganan Pegringsingan village reveals the form of power fight and ideology.  Therefore, this present study was aimed at finding the influence of the power domination and ideology revealed in the awig-awig text. By applying a critical discourse analysis, it was found the influence of the power domination depicted by the use of modality kawasa and wenang ‘may/can’. Most of the linguistic features used in the awig-awig text bring preservative ideologies that need to be promoted. However, in a small part of the linguistic features used in the text, especially in the social environment, implies destructive ideologies, such as marginalization and patriarchal that need to be resisted.
The Use of Hip Radiographs in Primary Care: The Inter-Observer Agreement of Reporting Native Hip Pathology
Authors: Kenyon Peter J. , Perry Daniel , Barrett Michael , Carroll Finton A. , Thomas Glyn
Published: October 2018

Introduction

Plain radiographs are often the first line investigation in identifying the cause of hip pain, though they do not differentiate all morphologically normal and abnormal hips. Interpretation of radiographs is subjective, depending on the patient history and physical signs. A radiological report can be misleading and may lead to, unnecessary radiation exposure, a delay in referral and a delay to definitive treatment. This study was to investigate the inter-observer reliability in the reporting of plain radiographs.

Methods

Sixty-one consecutive antero-posterior (AP) radiographs of native hips were identified that had been referred to one of the senior authors from the community with “hip pain”. Images were anonymised within PACS (picture archiving and communication system) and reviewed by a consultant orthopaedic surgeon, two consultant musculoskeletal radiologists, one senior orthopaedic registrar and one senior radiology registrar. Each reviewer was given a pre-constructed proforma, and asked to report the radiographs.

Results

There is a varying degree of ‘agreement’ for many of the commonly used terms on a hip radiograph. Agreement between all observers varied, by description, between 23.3% (CAM Lesion) to 93.3% (AVN). Multi-rater agreement showed Kappa values ranging from 0.12 (poor) to 0.6 (moderate). Overall there were widespread inconsistencies, even amongst the most widely used terms.

Conclusion

There is variable agreement amongst musculoskeletal radiology and orthopaedic experts when analysing plain radiographs of the native hip. This has implications for utility of reporting and therefore treatment in the community setting.
Plasma Ghrelin and von Willebrand Factor Levels in Patients with Non-Traumatic Osteonecrosis of the Femoral Head
Authors: Li Chenggang , Shen Lin , Yang Yanping , Shuai Bo , Xu Xiaojuan , Ma Chen
Published: October 2018

Objective

Increased evidence indicating ghrelin's direct influence on bone has been reported, but previous studies did not investigate its relationship with osteonecrosis of the femoral head (ONFH) in vivo. Coagulation disorders are considered to play important roles in ONFH. The aim of this study was to investigate the relationship of ghrelin, von Willebrand Factor (vWF) and other potentially relevant indicators with non-traumatic osteonecrosis of the femoral head.

Methods

Patients with non-traumatic ONFH (including steroid-induced, alcohol-induced, and idiopathic ONFH) and healthy controls were recruited for the study. We evaluated levels of plasma ghrelin and vWF. Other potentially relevant indicators, von Willebrand Factor cleaving protease (vWF-cp), plasminogen activator inhibitor 1 (PAI-1), tissue plasminogen activator (tPA), leptin, C-reactive protein (CRP), and lipid parameters were also assayed. Correlation coefficients and logistic regression models were used to assess the associations.

Results

Patients with non-traumatic ONFH had significantly lower ghrelin levels, higher vWF, PAI-1, CRP levels than those in healthy controls. Ghrelin level was negatively correlated with vWF after adjustment for other variables. Logistic regression model revealed that non-traumatic ONFH was independently associated with plasma ghrelin and vWF.

Conclusions

This study indicates that plasma ghrelin, vWF and PAI-1 levels were changed in patients with non-traumatic ONFH. Ghrelin in combination with vWF may prove to be involved in the pathogenesis of non-traumatic ONFH.

Authors: Çetinkaya Turan , Mutluer Ceren
Published: October 2018

Purpose of this study is to adapt Behavioral Regulation in Sports Questionaire  (BRSQ) which developed by Lonsdale, Hodge and Rose (2008) in Turkish and review psychometry properties. The scale consists of 24 items and 6 subdimension including intrinsic motivation, integrated regulation, identitied regulation, introjected regulation, external regulation and amotivation. Study group consists of total 681 student- athlete whom are licensed athletes and study at Physical Education and Sports College of Ahi Evran University, Erciyes University, Dumlupinar University and Çanakkale 18 Mart University. In order to determine psychometry properties of scale internal consistency, material and factor analysis and test- retest methods were applied. Cronbach alpha internal consistency coefficient of the measurement determined as follows; 0.790 for total points, 0.856 for intrinsic motivation subdimension, 0.838 for integrated regulation subdimension, 0.862 for identitied regulation subdimension, 0.740 for introjected regulation subdimension, 0.788 for external regulation subdimension and 0.800 for amotivation subdimension. In the analyzes performed, the data obtained from the exploratory and confirmatory factor analysis confirmed the 6-factor structure of the scale. In addition, scale-based analyzes yielded high test-retest scores. In this sense, it is considered that the scale is a valid and reliable measurement tool for the Turkish sample group.

Degenerative Rotator Cuff Tears: Refining Surgical Indications Based on Natural History Data
Authors: Keener Jay D. , Patterson Brendan M. , Orvets Nathan , Chamberlain Aaron M.
Published: October 2018

Degenerative rotator cuff tears are the most common cause of shoulder pain and have a strong association with advanced aging. Considerable variation exists in surgeons' perceptions on the recommended treatment of patients with painful rotator cuff tears. Natural history studies have better outlined the risks of tear enlargement, progression of muscle degeneration, and decline in the function over time. This information combined with the known factors potentially influencing the rate of successful tendon healing such as age, tear size, and severity of muscle degenerative changes can be used to better refine appropriate surgical indications. Although conservative treatment can be successful in the management of many of these tears, risks to nonsurgical treatment also exist. The application of natural history data can stratify atraumatic degenerative tears according to the risk of nonsurgical treatment and better identify tears where early surgical intervention should be considered.

Published: October 2018

The key to improve the precision of location fingerprinting algorithm is to reduce the errors between the position vectors in online locating process and the tag vector of the database in offline process. In view of the large errors caused by the construction of locating tags built from a single vector in traditional offline database, this paper proposed a kind of locating mapping tags for establishing the multi-mapping data structure and the offline database, which adapt better the distribution characteristics of RSSI signals in WIFI. Experiments showed that the offline database constructed by the methods effectively match the current actual position, reduce errors, and significantly improve the matching accuracy.
Marketing Research: Current State and Next Steps
Authors: Malhotra Naresh K.
Published: October 2018

We highlight the current state-of-the-art and identify trends that are likely to shape the role of marketing research in the future. We discuss the growing importance of marketing research and some of the factors that are driving its importance. The redefinition of the marketing researcher and the line of demarcation between marketing research and marketing management, and thus the distinction between marketing researchers and marketing managers, that is becoming thinner and thinner, is described. The sheer availability of secondary data is driving their importance. In a paradigm shift, more and more marketing research is and will be undertaken as part of normal on-going business operations, rather than in response to specific marketing problems or opportunities.

Dentre os instrumentos constitucionais de garantia cidadã, o Mandado de Injunção permanecia, até pouco tempo atrás, sem regulamentação legislativa. A omissão legislativa não impediu que a cidadania se apropriasse do instituto e o utilizasse largamente para demandar ao Judiciário a concretização de direitos fundamentais. Depois de um lento processo de consolidação, foi criada, em 2016, a lei do mandado de injunção. Contudo, diante das teorias que pugnam por um retorno da soberania popular aos debates constitucionais, em especial o constitucionalismo popular e o constitucionalismo democrático, e as teorias dialógicas que indicam o necessário debate entre as diversas instituições e poderes, cabe indagar sobre a necessária abertura procedimental do mandado de injunção às fórmulas de participação popular na jurisdição constitucional. A partir desta concepção teórica, o objetivo do artigo é examinar o Mandado de Injunção, utilizando-se de pesquisa documental, jurisprudencial e de revisão bibliográfica no campo do direito constitucional.
O juízo de retratação no código de processo civil de 2015 e a sua aplicação aos processos administrativos de defesa da concorrência: o desenvolvimento econômico a partir da economia e da celeridade processuais

Através da metodologia dedutiva com consulta em doutrina e legislação nacionais, analisa-se a aplicação do juízo de retratação do Código de Processo Civil de 2015 nos processos administrativos de defesa da concorrência. Primeiramente elenca-se as hipóteses previstas no CPC/2015 das decisões que comportam apelação com juízo de retratação. Em seguida, trata-se da aplicação do Código de Processo Civil nos processos administrativos do CADE, e em subcapítulo lida-se com o juízo de retratação conforme previsto no mesmo Código de Processo Civil e a relação com a lei 12.529/11. Por fim, nas considerações finais, entende-se pela validade da aplicação do juízo de retratação nos casos relativos aos procedimentos administrativos previstos na lei 12.529/11.
Sistema de precedentes brasileiro: compreensão crítica a partir da tradição inglesa e norte-americana
Authors: Pitta Rafael Gomiero , Cambi Eduardo Salomão
Published: October 2018

O novo Código de Processo Civil adotou instrumentos e métodos de julgamento por precedentes da cultura jurídica do common law. Porém, há perigos em importar um sistema metodológico desenvolvido por séculos para uma determinada cultura. Esse trabalho produz uma crítica à adoção do sistema de precedentes da common law e procura reforçar a ideia do stare decisis, abrido o caminho para o desenvolvimento de um sistema próprio, adequado à realidade processual brasileira, à cultura de litígio e ao contingente de processos em trâmite perante o Poder Judiciário. O artigo faz uso do método dedutivo, está baseado no exame da doutrina estrangeira e analisa as principais características dos precedentes nos Estados Unidos (EUA) e na Inglaterra.
Os direitos da mulher à luz do sistema universal de proteção e o potencial integrador dos tratados internacionais de direitos humanos: diálogos entre o global e o local
Authors: Taroco Lara Santos Zangerolame , Colares Ana Cecília Sabbá
Published: October 2018

Os principais documentos internacionais de tutela dos direitos humanos estabelecem a igualdade como um direito a ser efetivado, tendo este sido proclamado em diversas declarações. Não obstante, tal igualdade tem permanecido meramente formal, sendo árdua a tarefa de transformá-la em igualdade real entre mulheres e homens, principalmente quando se constata que a construção histórica dos direitos humanos sempre ocorreu com a exclusão da mulher e o reforço de ideologias patriarcais. O resultado desse desigual é a vulnerabilidade da mulher, advinda de um modelo de sociedade patriarcal, que afeta diretamente o cumprimento dos direitos humanos. Com base neste cenário, o presente estudo tem por objetivo apresentar os principais tratados internacionais relacionados com a proteção aos direitos das mulheres, em especial a Convenção sobre Eliminação de Todas as Formas de Discriminação contra a Mulher, adotando como técnica de pesquisa a revisão bibliográfica, manejada a partir do método dedutivo. Isso, com vistas a analisar como estes tratados são recepcionados e como essas normas internacionais influem ou podem influir na conformação do ordenamento jurídico brasileiro. O presente estudo parte da hipótese de que o devido enfrentamento das circunstâncias que propiciam a situação de vulnerabilidade de mulheres, atrelado ao combate à desigualdade de gênero é essencial para o combate da discriminação contra a mulher, e consequente proteção dos direitos humanos, razão pela qual é temática objeto de preocupação de várias instâncias internacionais.

Quanto ao avano terico, foi possivel observar que so necessrios mais estudos para avaliar a relao entre o greenwashing e a reputao das marcas. Contribuies sociais/para a gesto:A principal contribuio deste estudo foi comprovar que o greenwashing, ao ser percebido pelo consumidor em produtos verdes no varejo, existe um reflexo imediato e real na reputao da marca e na desconfiana no produto e isto, para uma empresa recuperar, muito custoso e demorado.
The subjective dimension of Security Education
Authors: Drabik Krzysztof
Published: October 2018

Subjectivity in education is not a new issue. It defines the position and role of participants
in educational processes (teacher, students). However, education combined with problems
of security may raise some doubts in interpretation. It is about identifying the subjects of
security. If you adopt the premise that a set of security subjects is not restricted to man and
social groups, then security education should also consider other subjects. Moreover, the
hazard society, as a product of the postmodern era involves the need for scientific research
and public discussion about man as the subject in the process of education and social
relations in general.
Analysis of the impact of changes in the stator magnetic circuit on static properties of the electromagnetic linear motor model
Authors: Just Krzysztof , Piskur Paweł
Published: October 2018

In this paper, the static characteristics as a function of changes in geometric dimensions
of the stator magnetic circuit of the linear stepper actuator with permanent magnets is presented.
The stator is built from a series of cylindrical coils encapsulated with ferromagnetic case. The runner
is made of permanent magnet rings connected with ferromagnetic spacers. The electromagnetic
interac-tion between the stator and the runner for the sequential supply of coils was analyzed.
The electro-magnetic force as a function of the geometry of the coils and the ferromagnetic housing
for the con-stant graduation of the runner was determined. The maximum, minimum, and average
values of the electromagnetic force as a function of the geometric independent variable were determined.
The ratio of the mean force to the maximum, and mechanical work calculated as the integral of the force
on the path of the runner was adopted as the evaluation criteria. A comparison between the maximum,
average and relative values of forces as a function of the geometric dimensions of the stator was made.
Keywords: modelling and simulation, linear actuator, finite element method, field calculations, cogging
force, magnetic force.
Verification of the equivalent stiffness method on the example of a model study of a two-span folding beam based on fixed supports
Authors: Marszałek Jan , Piechota Mieczysław
Published: October 2018

The article covers the analysis of the equivalent stiffness method in a two-span folding
beam based on fixed supports, carried out on the basis of model tests. The essence of this analysis was
to check the deformation of the entire beam for the constant equivalent stiffness. For this purpose,
detailed measurements of deflections at each beam connection were made for different: size of assembly
clearances, load values and length of the spans. Then, the results of the measurements were compared
with the theoretical results. Theoretical analysis was carried out using the strict method and the Finite
Difference Method. The conducted analysis confirmed the possibility of adopting constant equivalent
stiffness in two-span folding beams. This is a continuation of considerations regarding the work
of multi-span folding beams.
Keywords: civil engineering, folding bridges, equivalent stiffness, assembly clearance.
ACTUAL STATE AND FUTURE PROSPECTS OF LEGUME CULTIVATION IN POLAND
Authors: Bojarszczuk Jolanta , Księżak Jerzy
Published: October 2018

The aim of this article was to present the actual state and prospects for growing legume in Poland. Source material for study was mass statistics data published by the Central Statistical Office, reports of Institute of Agricultural and Food Economics and the results of the Multi-annual Program implemented in 2011-2015 and in 2016-2020. The analysis covered the years 2010-2017. In 2017, the area covered by legume crops totaled 272 thousand ha. However, the share of these crops in the cropping pattern exceeds only 2.5%. Legumes are characterized by a low level of commodity, which is caused by marginalization in the country of the market of protein raw material from native legumes. Increasing the interest of farmers in the production of legume seeds may take place through the creation of an appropriate market structure in the field of trade and use of legume seeds, which would facilitate too and create opportunities for cooperation with feed processing plants.
DYNAMICS AND STRUCTURE OF CREDIT COMMITMENTS OF AGRICULTURAL FARMS IN POLAND
Authors: Kata Ryszard
Published: October 2018

The analysis of the dynamics and structure of farmers' bank loans was made. The credit debt of farms in Poland was presented against the background of selected countries of the EU and USA. It was shown that the amount of farmers' credit commitments in Poland in 2002-2017 had a lasting upward trend. However, the debt-to-asset ratio of agricultural farms since 2008 has been gradually reduced. The level of farmers' credit indebtedness and the quality of their loan portfolio, in terms of the sector, do not indicate high financial risk for farmers and credit risk for banks. In the case of some indebted farms (about 1.5 thousand), however, there are serious risks related to loans taken and their repayment.
