Suburbanization, land use of TOD and lifestyle mobility in the suburbs: An examination of passengers’ choice to live, shop and entertain in the metro station areas of Beijing
Authors: Pengjun Zhao , Shengxiao Li
Published: February 2018

In the process of suburbanization of large growing cities, transit passengers have an undeniable role to play in terms of local traffic, car use, and petrol consumption. It is widely believed that transit-oriented development (metro station) could encourage people to live and consume near transit station areas through walking and cycling rather than travelling by car. However, opinions on this are still mixed. In addition, the existing literature is dominated by analyses of residents, while analyses of passengers remain scarce. This paper fills this gap by looking at metro station areas in Beijing. Using survey data, the study found mixed land use attracts passengers to shop more within metro station areas than in other places. More non-residential land developments attract more patrons to dine and access entertainment within metro station areas. Surprisingly, land use in the metro station areas was unrelated to passengers’ choice to live within metro station areas, while housing prices and income had significant effects. Personal preferences for travel mode have an effect, and those who dislike travel tend to shop and seek entertainment locally. This study suggests that land-use planning in metro station areas could be helpful in shaping more sustainable mobility in the process of suburbanization of China’s growing cities.
If we build it, who will benefit? A multi-criteria approach for the prioritization of new bicycle lanes in Quebec City, Canada
Authors: Grisé Emily , El-Geneidy Ahmed
Published: February 2018

Many cities across the world are actively promoting cycling through investments in cycling infrastructure, yet ensuring that the benefits from these investments are distributed equally in a region and not benefiting only one group is an important social goal. The aim of this study is to develop a methodology that can help in identifying where new bicycle facilities can be built in a region while prioritizing investments for those who need them most. The study uses Quebec City, Canada, as an example since the city has recently made a strong commitment to provide safe and attractive bicycle infrastructure to its residents. It also uses a GIS-based grid cell model to identify priority areas for cycling investment in different parts of the city. This is followed by a proposal for a new set of facilities based on a multi-criteria approach. These proposed facilities are then evaluated through a level of usage analysis to determine which routes will provide the maximum benefit to existing and potential cyclists. Finally, an equity analysis is conducted to evaluate whether the new facilities will meet some of the travel needs of individuals residing in socially deprived neighborhoods. This step in the evaluation process proposes a new social equity component in bicycle planning processes. This research can be of value to planners, engineers and policymakers working toward investments in bicycle facilities because it shows the full process of planning and evaluating different cycling facilities while incorporating social equity principles.

Authors: Hasdemir Mehmet , Ozudogru Hasim
Published: February 2018

The objective of this research was to assess satisfaction levels of the insured farmers towards TARSİM agricultural insurance services. The study was conducted on the farmers engaged in apricot production in Malatya province of Turkey, the world’s largest provider of apricots. About 69.88% of Turkey’s dried apricot production and about 73.44% of the world dried apricot production are based in Malatya. Face-to-face interviews were conducted with a random sample of 187 farmers. Likert scale questionnaires were used to collect opinion data of farmers on five dimensions, namely sales and marketing, damage compensation, pricing and payment policy, customer notification and customer representation. Structural equation modeling was used to explore the association between the measured variables and overall satisfaction levels. The results of structural equation modeling indicated that all dimensions had statistically significant effects on farmer satisfaction. Additionally, according to the standard estimations, satisfaction from sales and marketing, satisfaction from customer notification and satisfaction from damage compensation were the most significant determinants of customer satisfaction. Pricing and payment policy had the lowest influence on farmer satisfaction. The study results showed that efficient and rapid resolution of farmer problems and grant of ease for premium payments were the most influential factors affecting farmer satisfaction.

Authors: El-Maaty Hayam M. A. Abo , Sherif Sara Kh. , Foda Lina S. A.
Published: February 2018

The current study was designed to evaluate the effect feeding weaning rabbits sugar beet tops (SBT) with prebiotic on digestibility of nutrients and caecal microbial activity, volatile fatty acids estimation and organs histology. Fifty four 6-week-old unsexed weaning NZW rabbits were randomly distributed in a factorial (3 × 2) design to six equal groups. Sugar beet tops (SBT) was used at levels 0.0, 20 or 30% of the diet instead of the percent of alfalfa hay in the control diet in presence of 1.0 g/kg diet or absence of prebiotic (Perfect). Digestibility coefficients of dry matter (DM), crude protein (CP), ether extract (EE) and NFE of 12-week old NZW rabbits were improved by feeding SBT-containing diets. Dietary SBT level had no significant effect on pH value, TVFA,s and NH3-N values for caecum content of 12 weeks old NZW rabbits, however, total bacteria, E. coli and lactobacillus counts were significantly affected. Feeding SBT-containing diets did not alter plasma concentrations of AST and ALT of 12-week-old rabbits. Dietary prebiotic had a positive effect on the digestibility coefficients of DM, OM, CP, EE, CF and NFE of growing rabbits. Added prebiotic had a positive effect on caecal fermentative activities and caecal microbial activity of growing rabbits. The pH value, ammonia-N level, total bacteria and lactobacillus counts of rabbits fed prebiotic-supplemented diets were significantly higher but E. coli count was reduced as compared to control ones. This study concluded that sugar beet tops can be safely used in rabbit diets up to 30% instead of alfalfa hay.

Published: February 2018

We aimed to assess rice yield components as function of water stress imposed at distinct crop growth stages under greenhouse, in randomized block design under factorial scheme 3 × 4 + 1, with four replications. The factor “A” was the growth stage in which water stress was imposed, being (a) vegetative, (b) reproductive 1, and (c) reproductive 2; factor “B” was four levels of water stress (0-200 kPa). There was also an additional treatment consisting of a flooded check. Water was replenished to saturation every time the threshold stress was reached. At the end of the cycle, all panicles were counted and collected, per plant, for further analysis. In the lab, grains per panicle were counted, being classified either as whole kernel or aborted grains, whose results were used for obtaining sterility percentage. Whole kernel grains were weighted for obtaining the 1000 grains weight for each treatment, and the consequent plant grain yields. Number of panicles was not affected when stress was imposed after panicle initiation, but when imposed at tillering it was reduced; at grain filling, water stress promoted grains sterility higher than 90%; grain weight was only reduced when carbohydrates were directed to root formation in detriment of grain filling; lower rice grain yield per plant was observed even when treatments were maintained above 10kPa all along the cycle, compared to the flooded treatment.

This study aimed to evaluate the seasonal variation in concentrations of chlorophyll a, b, total chlorophyll and carotenoids in leaves of Hancornia speciosa, Gomes, during the periods of the year, relating them to the main phenological events, periods (rainy, dry and transitions) and populations evaluated. The survey was performed in three sites and the spatio-temporal analysis divided into four periods (rainy, rainy-drytransition, dry and dry-rainy transition), with 10 replicates (matrix plants). The data were collected in average intervals of 33 days from October 2014 to April 2017. The extraction and calculation of the chlorophyll and carotenoid contents of the leaves were expressed in mg/g DM, according to the equations of Arnon (1949) and Lichtenthaler (1987). There was a significant difference between the periods and sites analyzed for all pigments and their relationships. There was a greater amount of chlorophyll a than chlorophyll b; this difference was greater in the dry period. In the rainy period, we found a greater amount of total chlorophyll, carotenoids and total chlorophyll/carotenoid ratio. The behavior for the species follows that already observed for deciduous plants, closely related to water availability.

Published: February 2018

One of the priorities of the Ministry of National Defense is the creation of a new branch of Armed Forces – the Territorial Defense Forces (Polish: WOT). It was initiated by the establishment of the Territorial Defense Bureau, and then the Command of the Territorial Defense Forces. The process of creating brigades and sub-units of these troops is parallel to the completion of the WOT Command. The main idea of their functioning is the widespread, optional access of volunteers to serve under the so-called territorial military service.
Due to the intensive formation of new structures, a high-level military education is facing a major challenge, which is taking steps to urgently fill positions both for professional officers and for officers of territorial military service with graduates.
The material presented in the present paper is an attempt to analyze and propose solutions that are not necessarily final but are treated as a basis for further substantive discussion.

SOCIAL ENTREPRENEURSHIP IN THE SUSTAINABLE DEVELOPEMNT CONCEPT
Authors: GOLEŃSKI Wojciech
Published: February 2018

Sustainable development constitutes a paradigm which is to respond to the risks of our times (environmental, social and economic ones). It is based on the necessity to use resources in a way which will not deprive future generations of them. Such a development seeks to improve the quality of life of the community while maintaining social equality, diversity and the wealth of natural resources. It can be perceived as a broader social change which Jeremy Rifkin called “the third industrial revolution”, and whose symptoms can be seen today. Within the scope of this concept, there is the social entrepreneurship that, through the market activities, focuses on the social mission. Such a mission may concern a number of issues, such as social re-integration, fighting exclusion, or environment protection. Taking into account the importance of human resources, the social capital and economic efficiency of these enterprises and simultaneously focusing on environmental efforts, constitute a practical dimension of the sustainable development in local communities. One of the social cooperatives operating in the Opole voivodship is a good example here.

Authors: LUTY Witold , KUPICZ Włodzimierz , ZWIERZYŃSKI Marcin
Published: February 2018

In the era of the rapid development of motorization one of the most important character-istics of transport vehicles is the safety and comfort of their drivers and passengers. In par-ticular, people driving vehicles professionally are exposed to vibrations, which may ad-versely affect their bodies, causing discomfort, dysfunctions, and even lesions of disease. The vibration level triggered by the system a road – a vehicle depends on the type and pro-file of the road surface as well as the driving speed. Vibration levels are assessed by means of characteristics and comfort comparative indexes determined by experimental methods. Attempts at assessing the comfort while driving along paved roads may be found in many publications; however, there is a lack of information on testing vehicles moving in off-road conditions, which is substantial from the point of view of military vehicle crews’ comfort. The driving comfort of crews of wheeled vehicles is subjected to examinations at the Mili-tary Institute of Armored and Automotive Technology.

THE EUROPEAN UNION TOWARDS THE CRISIS IN UKRAINE
Authors: DEMKOWICZ Andrzej , SHEYAKOV Mukoła
Published: February 2018

The authors of this article are focusing on the role of the European Union in managing the crisis that occurred at its Eastern borders. The political conflict in Ukraine, which we have witnessed since 2013, entered a military phase. The European Union, in its sense of responsibility for shaping security at its borders, should have reacted adequately to circumstances. The implementation of the EU crisis response process occurred gradually, using, above all, diplomatic sources of crisis solving. All the same, despite the military capabilities for conflict management, the European Union did not decide to use them for shaping security in the Eastern part of Ukraine. The authors have attempted to describe the involvement of the European Union bodies in this process and to evaluate its effectiveness.In assessing such a critical but also sensitive area that is shaping security, it is important to remember about the limitations of the European Union as an organization consisting of sovereign states functioning in the international environment.The European Union, in its actions, needs to rely on the consensus of the variety of national interests of the member states as well as the credibility in implementing universal values, which the organization commonly declares and promotes among the international community.
LEGAL REGULATIONS IN THE FIELD OF CULTURAL HERITAGE PROTECTION IN POLAND IN THE YEARS 1944-1989 IN TERMS OF CULTURAL SECURITY OF THE COUNTRY
Authors: LANDMANN Tomasz
Published: February 2018

The article attempts to analyze the meaning of legal regulations developed in the field of cultural heritage protection in the years 1944-1989. It has been argued that these years were markedly different in terms of law in the sphere of cultural heritage protection than the period between 1918 and 1939 analyzed by the author in another article. The author decided to refer to legal acts and literature in the form of elaborations and magazines in the field of monuments protection. The specificity of the chosen subject and problem required the choice of a scientific method in the form of legal acts analysis, supported by literature review. The presented information shows that the period between 1944 and 1989 was characterized by a different approach of the Polish authorities towards the issue of cultural heritage protection in comparison to the years 1918-1939. The mentioned protection had an instrumental character and was one of the political-ideological tools influencing the society. Furthermore, the growth of legal protection of cultural assets in the age of the PRL took place in the conditions of centralized administration that adopted the idea of social distribution of many such assets, which led to devastation of numerous immovable monuments and sometimes also the antique furnishings. All the introduced legal regulations required a thorough change and redefinition of the legal status after the political-structural transformation of 1989.

Authors: MALINOWSKI Zdzisław
Published: February 2018

The aim of this article is to analyze the impact of new technologies on supply chain management in the Armed Forces. The supply chain is not limited to the operations related to the physical movement of goods, but also includes the management of relations with suppliers and customers. However, the supply chain management, through the integration and coordination of both information and goods flow, is a main factor of the well-developed customer service. The changes in military logistics imposed the necessity of implementation of the modern information technologies in the Polish Armed Forces. The Polish Army has adopted the Integrated Multi-level Information System of the Ministry of Defense (ZWSI RON). The article describes various technologies used in supply chain management including information, communication and automatic identification technologies. The author emphasizes that modern technologies are essential to enhance supply chain competitiveness and performance by improving the overall effectiveness and efficiency of the logistic system. Moreover, implementing of various innovative technologies shortens the time required for the fulfillment of tasks as well as reduces their labor consumption.
Methods of multidimensional comparative analysis – construction and application
Authors: Dmitruk Joanna , Gawinecki Jerzy
Published: February 2018

Methods of a multidimensional comparative analysis (MCA) rely on the ordering of a relatively homogeneous set of objects or features in order to make decisions regarding the choice of an object or feature according to a predetermined criterion. These methods are used to study directly immeasurable phenomena characterizing specific objects, subject to analysis. The article reviewed and characterized the methods of a multidimensional comparative analysis. An attempt was made to assess which methods may be particularly useful in an analysis of the capital market. The paper also presents examples of the use of selected MCA methods in form of the results of own research carried out in 2017 using the synthetic measure of taxonomic measure attractiveness of investment (TMAI) development. The obtained results were verified by comparing the value of TMAI with the real profitability of the investment, measured by the rates of return on shares of the surveyed listed companies.

Idea integracji sztuki z życiem w praktyce pedagogicznej (na podstawie badań młodzieżowych zespołów artystycznych)
Authors: Kowalczyk-Marcjan Małgorzata
Published: February 2018

At the time of postmodern deconstruction in thinking about aesthetic education, the concept
of prof. Irena Wojnar on the integration of art with daily life is still valid. In the 1980s and
1990s, the legitimacy of prof. Wojnar’s theory were our studies of amateur artistic teams from
youth vocational schools in Gorzów Wielkopolski, Lublin, Kraków, Andrychów, Koronowo,
Kołobrzeg.
Despite various profiles of the schools such as: mining, metallurgy, medicine, gastronomy,
railway, amateur creativity was developed within the three following stages: (1) social meetings
functioning instrumentally; (2) workshops enhancing the autonomy of art; (3) formation of
a lifestyle that shapes the hierarchy of values. The integration of art with daily life is not
limited to the past: Młodzi i teatr (‘Youth and the Theatre’) report prepared by the Malta Festival
Foundation in Poznań (2013) shows its usefulness in the educational practice. Together with
defining the typology of audience and the conditions for dissemination of the theatre, it
emphasises the need for a broader cultural participation in the debate on art creation within
the new social environment.

To investigate the feasibility of using next-generation sequencing (NGS) in the diagnostic laboratory to perform quantitative NPM1 mutation assessment using ultradeep (approximately 300 000×–500 000×) sequencing (NGS-qNPM1) as a method of assessing residual disease burden in patients with acute myeloid leukemia.

Design

A flexible NGS-based assay for the detection and quantitation of NPM1 mutations was developed by polymerase chain reaction amplification of target DNA sequences, sequencing on an Illumina (San Diego, California) MiSeq, and analyzing data with an in-house–designed bioinformatic pipeline. NGS-qNPM1 was compared with current NPM1 quantitation methods (real-time quantitative-polymerase chain reaction and multiparameter flow cytometry).

Results

The NGS-qNPM1 assay had a sensitivity of between 10−4 and 10−5 and showed high concordance and correlation with reference methodologies. Moreover, the NGS-qNPM1 assay was able to be integrated into the laboratory's existing, targeted amplicon-based sequencing workflow.

Conclusions

An NGS-based, quantitative NPM1-mutation assessment can be used to monitor patients with acute myeloid leukemia, and it has some practical advantages over existing modalities.

Understanding biodiversity at local and regional requires a global context. This talk presents the global pattern of marine species richness and endemicity, including latitude and depth. We compare maps of marine species endemicity across all taxa (65,000 species), and particular taxa (razor clams, amphipods, polychaetes, seagrass, jellyfish, bryozoans, fish), with a new map of marine ecosystems based on analysis of 20 environmental variables. We show how species richness increases with temperature but dips at the equator, and decreases with depth. Thirty biogeographic realms are distinguished based on species endemicity, with more in coastal than offshore areas. Species richness and endemicity are higher in benthic than pelagic taxa, and macro- than micro- and mega-fauna. However, we should expect individual taxa to vary from these overall patterns due to their evolutionary origins and competition with other taxa; and patterns within geographic regions to vary due to constancy of some environmental variables (e.g. temperature) and local scale habitat variation. Thus nesting of taxon and regional studies within this global context may indicate how ecological interactions have shaped the global evolution of marine biodiversity.
Twenty steps towards an adequate inferential interpretation of p-values

Published: February 2018

We suggest twenty immediately actionable steps to reduce widespread inferential errors related to “statistical significance testing.” Our propositions refer first to the theoretical preconditions for using p-values. They furthermore include wording guidelines as well as structural and operative advice of how to present results, especially in multiple regression analysis. Our propositions aim at fostering the logical consistency of inferential arguments by avoiding false categorical reasoning. They are not aimed at dispensing with p-values or completely replacing frequentist approaches by Bayesian statistics.

Protein phase separation is implicated in formation of membraneless organelles, signaling puncta and the nuclear pore. Multivalent interactions of modular binding domains and their target motifs can drive phase separation. However, forces promoting the more common phase separation of intrinsically disordered regions are less understood, with suggested roles for multivalent cation-pi, pi-pi, and charge interactions and the hydrophobic effect. Known phase-separating proteins are enriched in pi-orbital containing residues and thus we analyzed pi-interactions in folded proteins. We found that pi-pi interactions involving non-aromatic groups are widespread, underestimated by force-fields used in structure calculations and correlated with solvation and lack of regular secondary structure, properties associated with disordered regions. We present a phase separation predictive algorithm based on pi interaction frequency, highlighting proteins involved in biomaterials and RNA processing.
YTH-RNA-binding protein prevents deleterious expression of meiotic proteins by tethering their mRNAs to nuclear foci

Accurate and extensive regulation of meiotic gene expression is crucial to distinguish germ cells from somatic cells. In the fission yeast Schizosaccharomyces pombe, a YTH family RNA-binding protein, Mmi1, directs the nuclear exosome-mediated elimination of meiotic transcripts during vegetative proliferation. Mmi1 also induces the formation of facultative heterochromatin at a subset of its target genes. Here, we show that Mmi1 prevents the mistimed expression of meiotic proteins by tethering their mRNAs to the nuclear foci. Mmi1 interacts with itself with the assistance of a homolog of Enhancer of Rudimentary, Erh1. Mmi1 self-interaction is required for foci formation, target transcript elimination, their nuclear retention, and protein expression inhibition. We propose that nuclear foci formed by Mmi1 are not only the site of RNA degradation, but also of sequestration of meiotic transcripts from the translation machinery.

Cancer cases result in 13% of all deaths worldwide. Unwanted side effects in patients under conventional treatments have led to the search for beneficial alternative therapies. Microalgae synthesize compounds with known in vitro and in vivo biological activity against different tumor cell lines. Therefore, native microalgae from the State of Nuevo Leon, Mexico may become a potential source of antitumor agents. The aim of the present study was to evaluate the in vitro cytotoxic effect of Nuevo Leon regional Chlorella sorokiniana (Chlorellales: Chlorellaceae) and Scenedesmus sp. (Chlorococcales: Scenedesmaceae). Native microalgae crude organic extracts cytotoxicity against murine L5178Y-R lymphoma cell line and normal lymphocyte proliferation were evaluated using the MTT reduction colorimetric assay. Cell death pathway was analyzed by acridine orange and ethidium bromide staining, DNA degradation in 2% agarose gel electrophoresis and caspases activity. Results indicated significant (p < 0.05) 61.89% ± 3.26% and 74.77% ± 1.84% tumor cytotoxicity by C. sorokiniana and Scenedesmus sp. methanol extracts, respectively, at 500 µg/mL, by the mechanism of apoptosis. This study contributes to Mexican microalgae biodiversity knowledge and their potential as antitumor agent sources.
The Temperature Sensitivity (Q10) of Soil Respiration: Controlling Factors and Spatial Prediction at Regional Scale Based on Environmental Soil Classes

Published: February 2018

The temperature sensitivity of heterotrophic soil respiration is crucial for modeling carbon dynamics but it is variable. Presently, however, most models employ a fixed value of 1.5 or 2.0 for the increase of soil respiration per 10°C increase in temperature (Q10). Here we identified the variability of Q10 at a regional scale (Rur catchment, Germany/Belgium/Netherlands). We divided the study catchment into environmental soil classes (ESCs), which we define as unique combinations of land use, aggregated soil groups, and texture. We took nine soil samples from each ESC (108 samples) and incubated them at four soil moisture levels and five temperatures (5–25°C). We hypothesized that Q10 variability is controlled by soil organic carbon (SOC) degradability and soil moisture and that ESC can be used as a widely available proxy for Q10, owing to differences in SOC degradability. Measured Q10 values ranged from 1.2 to 2.8 and were correlated with indicators of SOC degradability (e.g., pH, r = −0.52). The effect of soil moisture on Q10 was variable: Q10 increased with moisture in croplands but decreased in forests. The ESC captured significant parts of Q10 variability under dry (R2 = 0.44) and intermediate (R2 = 0.36) moisture conditions, where Q10 increased in the order cropland<grassland<forest. Overall, the estimated heterotrophic CO2 release from the catchment was up to 45% lower when ESC‐ and moisture‐specific Q10 values were used instead of 1.5, suggesting that scaling Q10 on the basis of both ESC and moisture might be a promising concept for spatially continuous assessments of carbon turnover at regional scales.
