The psychology of “swiping”: A cluster analysis of the mobile dating app Tinder
Authors: Rochat Lucien , Bianchi-Demicheli Francesco , Aboujaoude Elias , Khazaal Yasser
Published: October 2019

Background and aims

The use of the smartphone dating application Tinder is increasingly popular and has received much media attention. However, no empirical study to date has investigated the psychological characteristics driving its adaptive or problematic use. The aim of this study is to determine whether reliable subtypes of users can be identified via a cluster analysis approach.

Methods

A total of 1,159 Tinder users were recruited. Survey questions investigated user characteristics, including: motives for app use, sexual desire, attachment styles, impulsivity traits, self-esteem, problematic use, depressive mood, and patterns of use.

Results

Four reliable clusters were identified: two with low levels of problematic use (“regulated” and “regulated with low sexual desire”), one with an intermediate level of problematic use (“unregulated-avoidants”), and one with a high level of problematic use (“unregulated-highly motivated”). The clusters differed on gender, marital status, depressive mood, and use patterns.

Conclusion

The findings provide insight into the dynamic relationships among key use-related factors and shed light on the mechanisms underlying the self-regulation difficulties that appear to characterize problematic Tinder use.
Cooperation on Parity Basis in Innovative Development of the Agrarian Sector of the Republic of Crimea
Authors: Maidanevich Petr
Published: October 2019

The article studies the essence and role of innovations in the development of society together with the stages and directions of scientific research of the economy innovative development. The author presents the importance of innovative economy at different levels of administration as well.
The paper considers the prospects of innovative activity in regional and sectoral aspect on the basis of the priority of developing industries forming the state budget, which are economically and socially significant. The author defines that the innovative character of agrarian business is determined not only by general trends of scientific and technical progress of economy but also by the necessity of providing growing food requirements of the population.
The object of the conducted research is the development, theoretical and methodical justification of creating a territory of innovative development within the agrarian sector of the Republic of Crimea.
The research evaluates social and economic indicators of the agrarian sector in the Republic of Crimea; identifies problematic issues of its subjects’ activity; and determines the main ways of solving them in the frame of creating an innovative and effective territory according to the principles of parity cooperation.
In this context the innovative territory is understood as an open system operating in a specific external environment caused by certain factors which represent a part of the social, economic and national innovative systems. The coordination of integrity of all subjects’ activities has to become a distinctive feature of a system positively affecting management at the regional level.
The effectiveness of innovative territory functioning is expected to be determined by a set of indicators of the qualitative creation of innovative infrastructure including informational, organizational, marketing, educational and other institutes which ensure practical implementation and commercialization of innovative products. Public and private partnership in the form of establishing specialized financial institutions providing their interaction with scientific and production organizations has to become a conceptual basis of state regulation in this direction.
Role of Cluster Policy in the Socio-Economic Development of Abkhazia
Authors: Mirtskhulava Illona
Published: October 2019

The economy of Abkhazia is experiencing a systemic crisis caused by political, economic, social, demographic difficulties of the last quarter of the century and is characterized by low living standards, regional development imbalance, subsidized budgets of different areas, and a significant share of the shadow economy. The analysis of the main indicators of the socio-economic situation shows that the economy of Abkhazia is developing by inertia, having exhausted the potential of the previous stage of development. The relevance of the work lies in finding new economic tools and social technologies, which will allow to take the post-war Abkhazia out of the recession. New approaches are required for sustainable development. The purpose of this article is to study and search for mechanisms that will help in modernizing the socio-economic situation of Abkhazia in terms of informational economy. The author suggests implementing cluster associations in the Republic of Abkhazia as an effective form of economic interaction between economic entities. The article describes economic actors of a cluster organization, the role of entities and the conditions of forming economic and institutional clusters, as well as the competitive advantages of the national economy of Abkhazia. The author of the article proposes tools for implementing cluster policy, describes its advantages and expected results. The proposed approach will make it possible to minimize the risks of imbalances, create conditions for economic growth and improve the quality of life of the population of Abkhazia.

“It’s Not Your Everyday Classroom”
Authors: Byrd Kymberly
Published: October 2019

A school-based enterprise (SBE) is an entrepreneurial operation managed and operated by students in a school setting.  School-based enterprises reinforce classroom instruction through practice-based learning and can enhance creativity, innovation, problem-solving, critical thinking, and other skills. In addition to creating a more engaging, enriching learning environment, SBE bridges the gap between classroom instruction and the world of work and can benefit students, schools, and communities. This paper utilized the systems view of school climate framework to assess differences in perceptions of school climate between students participating in SBE and students not participating in SBE at a high school in the Mississippi River Delta Region. The qualitative analysis of five focus groups with 36 students examined differences in relationships, values, and beliefs and findings indicated that SBE can produce more meaningful, enriching learning experiences than students not participating in SBE. This research adds to the sparse empirical analyses of SBE and suggests directions for future inquiry.
Mizzou Missteps
Authors: McGuire Lauren Elizabeth
Published: October 2019

By denying that issues of bias and mistreatment exist and then confronting such issues with disdain, some White Americans enable injustice and abet systems of oppression. Black students at the University of Missouri in fall 2015 had seen this narrative ring true several times. The resulting events, including protests, a hunger strike, and several administrator resignations, cast light on the experience of black students at Mizzou through nationwide media coverage.

This case study examines three opportunities turned missteps of administrators that exacerbated an already charged, contentious environment: the president’s refusal to acknowledge protestors at a homecoming parade, a too-little-too-late meeting with stakeholders, and the impacts of the football team’s involvement. In a country whose everyday population growth is 90 percent non-white, a greater awareness of the racial inclusion work needed on college campuses today is necessary. I hope my narrative heightens this awareness.
Alice ainda mora aqui: narrativa juvenil contemporânea
Authors: Martha Alice Áurea Penteado
Published: October 2019

Resumo A compreensão de que reside na possibilidade de reconhecer nos textos que lemos aquilo que experimentamos na realidade, expressar, traduzir e dar forma às emoções e aos sentimentos que nos atormentam ou alegram, leva-nos à abordagem do tema da identidade, que conduz a escolhas, relacionamentos, enfim, a situações limites, que configurem, no plano ficcional, etapas da evolução vividas pelo ser humano e que possam traduzir, ao mesmo tempo, modos de preservação da identidade cultural e de participação do processo de universalização. Tais aspectos serão focalizados em narrativas da literatura juvenil contemporânea brasileira, Alice no espelho, de Laura Bergallo, e A maldição do olhar, de Jorge Miguel Marinho, considerando, especialmente, a diversidade das visões oferecidas pelas perspectivas internas dos textos, cuja interação possibilita a emergência do objeto estético, na perspectiva de Wolfgang Iser.
De (re)conto e (des)encanto: uma leitura de Fita verde no cabelo
Authors: Pereira Elvya Ribeiro
Published: October 2019

Resumo Fita verde no cabelo: nova velha história, conto de Guimarães Rosa, apresenta uma leitura de Chapeuzinho Vermelho. Como indica o subtítulo - nova velha história -, a narrativa rosiana ressignifica as versões tradicionais de Chapeuzinho, projetando a história em meio à perplexidade do mundo contemporâneo, desconstruindo certezas, deslocando fantasias. A partir de reflexões sobre a tradição oral, narrativa e memória, negação da experiência no mundo contemporâneo, pretendemos mostrar como o conto de Guimarães Rosa problematiza a trajetória da protagonista, Fita-Verde, num desdobrar-se em simbiose com a fala-fato de um narrador que trama o destino desta lendária menina, agora em situação dramática, evocando gestos e arquétipos que lhe escapam nos desvãos de uma consciência desencantada. A velha fantasia do tempo das fadas, requisitada pelo seu ser de linguagem e seu universo ontologicamente situado no próprio enredo do conto, sofre os refluxos de um tempo de crises, em que o confronto com a solidão é uma face da morte.
Notes on the Trip to the Great Savannah
Authors: Carpentier Alejo , Rogers Charlotte
Published: October 2019

In July 1947, the Cuban Author Alejo Carpentier traveled from his home in caracas to the sparsely inhabited interior of venezuela, visiting the country's tropical forests and its great plains. At the time, Carpentier was known principally as a music critic and newspaper columnist for El Nacional in Venezuela and Carteles in Cuba; he had yet to publish El reino de este mundo (The Kingdom of This World; 1949), which would launch his career as a novelist and earn him international renown. Carpentier later wrote a novel about a trip much like the one he took in 1947. In the now-canonical Los pasos perdidos (The Lost Steps; 1953), a failed composer finds inspiration by traveling from a cosmopolitan city to the tropical forests of South America. Carpentier's creativity was similarly sparked by his trip to the Venezuelan wilderness, as his travel diary Notas del viaje a la Gran Sabana (Notes on the Trip to the Great Savannah) makes clear. Notas is the only contemporary account of the journey written by Carpentier, who later made contradictory statements about the details and even the number of trips he took. Beyond its documentary value, the travel diary reveals that Carpentier's experience was deeply enmeshed with his readings, a characteristic that also marks the narrator-protagonist of Los pasos perdidos. Moreover, Notas is of broad ecocritical and historical significance because it makes clear the extent to which the forests and plains of South America were changing during Venezuela's boom in oil drilling and gold mining in the 1940s. Inspired by what he witnessed in Venezuela, Carpentier created the central drama of Los pasos perdidos out of his protagonist's desire to inhabit what the author called the “mundo del Genesis” (“world of Genesis”) at a time when extractive industries were rapidly transforming the economies, ecologies, and societies of the region (“La Gran Sabana” 32).
Facts Shifting to the Left: From Postmodernism to the Postfactual Age
Authors: Koschorke Albrecht , Thomas Michael , Rossman Sasha
Published: October 2019

How postmodern is populism? Is there a hidden legacy of the 1968 manifestos in today's right-wing protest culture? In recent years, questions like these have often been posed in a more or less polemical manner. They should be reconsidered in a more sober, nuanced way. In academia, they are of far more than merely historical interest since unlike the hairstyles, clothing fashions, body culture, and living spaces from the late 1960s, many of the theories from that period are still regarded as contemporary. Above all, this applies to poststructuralism as a collective name for the impulses of what is often called French theory, which have set the tone in the humanities for two generations. However, the problem with the continuing topicality of poststructuralist and postmodern ways of thinking is that many of their elements are becoming virulent under completely changed political circumstances.
When Nothing Is True, Everything Is Possible: On Truth and Power by Way of Socialist Realism
Authors: Lee Haiyan
Published: October 2019

In this essay, i contend that our current crisis of truth, however distressing, is a replay of an earlier one that saw a far-reaching, devastating destruction of truth. The simultaneous recrudescence of right-wing populism and dawn of the post-truth age recall the way totalitarian movements in the twentieth century exposed the masses to organized lying. Today, the plague of so-called alternative facts and fake news, while incubated and spread by digital technology, can, like totalitarianism's organized lies, be traced back to the erosion of democratic institutions and the loss of faith in democracy's foundational narratives. To understand how our contemporary politics could be going down the dark lane of history again, I turn to the political philosophy of Claude Lefort, Anthony Giddens, and Hannah Arendt, who have written perspicaciously on what happens to truth when the citizenry collectively disinvests from common knowledge and disbelieves in the common good.

Lessons Learned

Alectinib confers a pronounced survival benefit in patients with ALK rearrangement-positive non-small cell lung cancer and a poor performance status. Survival benefit of alectinib for patients with a poor performance status was consistent regardless of the presence of central nervous system metastases.

Background

We previously reported a marked objective response rate (ORR) and safety for alectinib treatment in patients with ALK rearrangement-positive non-small cell lung cancer (NSCLC) and a poor performance status (PS) in the Lung Oncology Group in Kyushu (LOGiK) 1401 study. It remained unclear, however, whether alectinib might also confer a long-term survival benefit in such patients.

Methods

Eighteen patients with ALK rearrangement-positive advanced NSCLC and a PS of 2, 3, or 4 (n = 12, 5, and 1, respectively) were enrolled in LOGiK1401 between September 2014 and December 2015 and received alectinib. We have now updated the survival data for the study.

Results

The median follow-up time for all patients was 27.3 months. The median progression-free survival (PFS) was 16.2 months (95% confidence interval [CI], 7.1–30.8 months), and the median survival time (MST) and the 3-year overall survival rate were 30.3 months (95% CI, 11.5 months to not reached) and 43.8% (95% CI, 20.8–64.7%), respectively. This survival benefit was similarly manifest in patients with a PS of 2 (MST, 20.5 months) and those with a PS of ≥3 (MST, not reached). PFS did not differ between patients with or without central nervous system (CNS) metastases at baseline (median of 17.5 and 16.2 months, respectively, p = .886).

Conclusion

Alectinib showed a pronounced survival benefit for patients with ALK rearrangement-positive NSCLC and a poor PS regardless of the presence of CNS metastases, a patient population for which chemotherapy is not indicated.

Laboratory method design for investigating the phytoremediation of polluted water
Authors: Jacklin DM , Brink IC , De Waal J
Published: October 2019

The performance of plants to remove, remediate or immobilise environmental contaminants in a growth matrix through natural biological, chemical or physical activities was studied in a laboratory phytoremediation system. This study aimed to develop a novel phytoremediation system capable of investigating the remediation of agricultural pollutants by individual and multiple plant species. The designed system analysed community phytoremediation by uniquely implementing multiple plant species within the same growth silo, with indigenous and alien assemblages compared to establish community performance, highlighting the importance of biodiversity in plant assemblages. The constructed system successfully analysed the phytoremediatory capabilities of plant species within the critically endangered Renosterveld vegetation type, with unvegetated soil controls included to illustrate the pollutant removal efficiency of plants only. Growth silos were constructed from PVC piping and irrigated with drippers from a submersible pump. Eighteen different plant species were included in the experiment, i.e., 14 indigenous species, 3 invasive alien plant (IAP) species, and Palmiet. Five agricultural pollutant parameters were analysed, i.e., for fertilizers NH3-N, NO3--N and PO43--P and for herbicide contamination using two glyphosate concentrations. The growth silos and unvegetated soil control were irrigated using a pollutant–municipal water solution at 3-day intervals. The multiple plants per silo design approach seeks to contribute to the limited literature pertaining heterogeneity importance, by comparing the pollutant removal performance of plant assemblages. Community comparison further investigated the biofilter implementation potential of indigenous South African plants as an alternative to their more invasive alien counterparts, adding to the knowledge base of plant-based phytoremediation by indigenous South African plant species. The laboratory phytoremediation system successfully measured the agricultural pollutant removal performance of individual plants and vegetative communities, with soil remediation influence acknowledged. The proposed system is a simple and inexpensive method for obtaining the plant-based biofiltration efficiency of individual and multiple plant species.
Assessing the influence of DEM source on derived streamline and catchment boundary accuracy
Authors: Mashimbye Zama Eric , De Clercq Willem Petrus , Van Niekerk Adriaan
Published: October 2019

Accurate DEM-derived streamlines and catchment boundaries are essential for hydrological modelling. Due to the popularity of hydrological parameters derived mainly from free DEMs, it is essential to investigate the accuracy of these parameters. This study compared the spatial accuracy of streamlines and catchment boundaries derived from available digital elevation models in South Africa. Two versions of Stellenbosch University DEMs (SUDEM5 and DEMSA2), the second version of the 30 m advanced spaceborne thermal emission and reflection radiometer global digital elevation model (ASTER GDEM2), the 30 and 90 m shuttle radar topography mission (SRTM30 and SRTM90 DEM), and the 90 m Water Research Commission DEM (WRC DEM) were considered. As a reference, a 1 m GEOEYE DEM was generated from GeoEye stereo images. Catchment boundaries and streamlines were extracted from the DEMs using the Arc Hydro module. A reference catchment boundary was generated from the GEOEYE DEM and verified during field visits. Reference streamlines were digitised at a scale of 1:10 000 from the 1 m orthorectified GeoEye images. Visual inspection, as well as quantitative measures such as correctness index, mean absolute error, root mean squares error and figure of merit index were used to validate the results. The study affirmed that high resolution (<30 m) DEMs produce more accurate parameters and that DEM source and resampling techniques also play a role. However, if high resolution DEMs are not available, the 30 m SRTM DEM is recommended as its vertical accuracy was relatively high and the quality of the streamlines and catchment boundary was good. In addition, it was found that the novel Euclidean distance-based MAE and RMSE proposed in this study to compare reference and DEM-extracted raster datasets of different resolutions is a more reliable indicator of geometrical accuracy than the correctness and figure of merit indices.
Short communication: Detection of selected agricultural pesticides in river and tap water in Letsitele, Lomati and Vals–Renoster catchments, South Africa
Authors: Machete M , Shadung JM
Published: October 2019

This paper presents the levels of detection of selected agricultural pesticides in river and tap water in the Letsitele, Lomati and Vals–Renoster catchments, South Africa. Agriculture plays a major role in the development of communities through job creation and poverty eradication. However, exposure to agricultural pesticides can result in serious human health and environmental effects. This study, therefore, identified critical areas where specific pesticides might result in high environmental and human health risks. Three water catchment areas, namely, Letsitele, Lomati and Vals–Renoster, were identified for raw and tap water analysis. The results confirmed the presence of selected agricultural pesticides:  atrazine, terbuthylazine, imidacloprid, metolachlor, simazine and alachlor. Although low concentrations of most of these pesticides were detected, pesticides such as atrazine, alachlor and simazine are known for endocrine disruption. A critical finding of this study is the detection of these pesticides in tap water (drinking water) of a primary school in the Lomati catchment. This reveals a high exposure potential for human health. It is thus recommended that further research be conducted to determine the potential health risks associated with these pesticides among vulnerable communities, through epidemiological studies.
Effect of cultural management methods against fake butterfly [Ricania japonica (Hemiptera: Ricaniidae)]
Authors: ALTAŞ Kaan , AK Kibar
Published: October 2019

This
study was conducted between 2017 and 2018 to determine the cultural measures
that are applied in the control against Ricania
japonica (Hemiptera: Ricaniidae), which has caused damage in the Eastern
Black Sea Region of Turkey for approximately 10 years as an important pest.
Pests are widespread in this region but there is no other important pest that
requires significant chemical control in crop plants, in particular tea plants.
Furthermore, this pest population, whose population has grown since 2009, may
cause significant losses in vegetables especially for traditional family needs
during its nymph period. The fact that vegetable fields have been almost
interwened with tea plants and synthetic pesticides are not used in tea plant
production, has caused us to focus on cultural methods, which are among
alternative pest-fighting methods. With this study, the purpose was to
determine the effects of kaolin, refined salt and ash applications against the
nymphs of the pests, and to investigate how to destroy the infected plant
materials in which the pest lay eggs until the middle of May. As a result of
the study, it was determined that the destruction of the infected plants and
plant wastes in the areas decreased the pest population by 90% because it was
the winter months which is the egg-laying period of the pest. Other
applications (kaolin, refined salt and ash) were not found effective against
the nymphs of this pest.

MINUTE ChIP v1
Authors: Kumar Banushree , Elsässer Simon
Published: October 2019

The need for quantitative ChIP-seq has been widely appreciated, and a number of quantitative methods have been proposed. Mint-ChIP, developed by the Bernstein lab provides a streamlined one-pot chromatin barcoding and a post ChIP linear amplification that requires only one adaptor per chromatin fragment. Here, we introduce unique molecule (unique molecular identifier [UMI]) counting and paired-end mapping of the chromatin fragments to this method, which we then termed MINUTEChIP for multiplexed indexed unique molecule T7 amplification end-to-end sequencing. For paired-end mapping, we modified the linear amplification strategy introduced in Mint-ChIP by priming the cDNA synthesis from a 30 adaptor (RA3) ligated onto the amplified RNA, thus maintaining the original genomic fragment length, retrieving atypical mononucleosomal fragment length for histone ChIP. We have also optimized the ligation conditions and stoichiometry of adaptors to chromatin to enable sequencing of the input. We show that MINUTE-ChIP is a sensitive method with a large linear dynamic range for accurately quantifying relative differences in genome-wide histone modification patterns across multiple pooled samples.

Published: October 2019

The advent of low‐cost continuously recording cable‐free autonomous seismographs, commonly referred to as nodes, enables dense spatiotemporal sampling of seismic wavefields. We create virtual source reflection profiles using P waves from five teleseismic events recorded by the Sevilleta node array experiment in the southern Albuquerque basin. The basin geology records a structurally complex history, including multiple Phanerozoic orogenies, Rio Grande rift extension, and ongoing uplift from a midcrustal magma body. The Sevilleta experiment densified the long term, regionally sparse seismograph network with 801 single channel vertical‐component 10 Hz geophone nodes deployed at ∼300  m spacing for 14 days in February 2015. Results show sediment‐basement reflections at <5  km depth and numerous sub‐basin structures. Comparisons to legacy crustal‐scale reflection images from the Consortium for Continental Reflection Profiling show agreement with structural geometries in the rift basin and upper crust. Comparisons of the teleseismic virtual reflection profiles to synthetic tests using 2D finite‐difference elastic wave propagation show strong P‐to‐Rayleigh scattering from steep basin edges. These high‐amplitude conversions dominate the record sections near the western rift margin and originate at the Loma Pelada fault, which acts as the primary contact between rift‐bounding basement‐cored fault blocks and rift basin sediments. At near offsets, these signals may interfere with interpretation of upper crustal structure, but their relatively slow moveout compared to teleseismic P‐wave multiples provides clear temporal separation from sediment‐basement reflections across most of the array. The high‐signal‐to‐noise ratio of these converted Rayleigh‐wave signals suggests that they may be useful for constraining short‐period (∼1  Hz) dispersion with strong sensitivity in the uppermost ∼1  km of the rift basin sediments.
The use of information technology in human resource management in American enterprises
Authors: Karasek Aneta
Published: October 2019

Theoretical background: The ongoing development of information technology (IT) has caused IT solutions to be increasingly applied in human resource management (HRM). The implementation of such solutions is highly advantageous to enterprises because they streamline the provision of services to job candidates and employees, and save time and money. This is particularly important for high-tech enterprises using the latest scientific and technological advances and innovative solutions.

Purpose of the article: The objective of the study was to examine the use of IT tools in recruitment and selection, development and training, motivation, talent management and personnel services. Research methods: The research employed the case study method. Documentation analysis, interview techniques and observations were carried out in enterprises. The paper describes three case studies of high-tech companies headquartered in Silicon Valley in the United States.

Main findings: High-tech enterprises in Silicon Valley deploy a wide range of IT tools for recruitment and selection, development and training, motivation, talent management and human resource (HR) services, thus supporting personnel management processes and increasing the efficiency of administrative tasks. The type and scope of the applied IT solutions depended on the size of the company. Large enterprises had a tendency to integrate specific tools used in HR processes into one employee management system. The research showed a number of advantages regarding IT tool implementation in HRM, such as improved HR management efficiency due to data integration, obtaining a better match between employee competences, their development capacities and company demands. Moreover, the use of IT tools increased employee engagement in the performance of tasks. The implementation of IT tools in HRM produces certain limitations since technologies can be static and information can be transferred in one direction only. Therefore, face-to-face relationships, opportunities for sharing opinions between employees and prospects for development are essential in enterprises because they impact employee engagement.

In the model of induced neuronal resistance to the toxic effect of glutamate (deprivation of trophic factors), exosome secretion is demonstrated. Exosomes are secreted at the development of resistance during deprivation and at the first 24 h after preconditioning, as was shown by dot blot of extracellular fluid using anti-CD63 antibody. The autophagy inhibitor bafilomycin (0.01 μM) significantly reduces the quantity of the secreted exosomes at the stage of autophagy induction and at 24 h after induction. At the same time, inhibition of autophagy during the deprivation of trophic factors prevents the development of resistance, but inhibition of autophagy during the first 24 h after deprivation does not affect the development of resistance. We suggest that the long-term effects of preconditioning may be mediated by exosome secretion.

It is very important to be able to predict the breakthrough time of gas mask filters under real life circumstances. This article describes the use of a very simple predictive equation, the Wheeler-Jonas equation, that yields excellent predictions but only within a very restrictive set of boundary conditions. In order to make this model work in a more realistic environment, it has been gradually adapted to take into account a number of parameters related to this environment: a non-constant inlet concentration, a breather flow, new physical forms of activated carbon, the relative humidity and temperature of the ambient air, chemisorbed gases and mixtures of organic vapours. As (nearly) all of these parameters can be calculated independently of each other, based on data that are either readily available or that can be measured, their influence on the complexity of the model stays low. This makes this combined model both easy to use and powerful in predicting breakthrough times of gas mask filters under real-life conditions.

This article presents results of carbon nanotubes synthesis from household high-density polyethylene waste by thermal decomposition. A specific feature of this work is that the decomposition of high-density polyethylene waste and synthesis of carbon nanotubes were carried out in one-step using three-zone chemical vapor deposition reactor. The effect of temperature in the range of 450‒550 °C on decomposition products of high-density polyethylene was investigated. The decomposition products of polyethylene wastes were investigated by IR Fourier spectroscopy. Cenospheres obtained from ash and slag waste from thermal power plants during coal combustion were used as a catalyst for the synthesis of carbon nanotubes. The cenospheres were impregnated with an aqueous solution of iron nitrate. It was found that as a result of thermal decomposition of high-density polyethylene waste at temperature of 450 °C, gaseous carbon-containing compounds are formed, which upon further heating to 800 °C lead to the formation of carbon nanotubes with a diameter of 16‒21 nm on the surface of catalyst. Physicochemical analysis showed that turbostratic carbon is almost completely absent in the formed product. Carbon nanotubes analysis was performed by scanning electron microscopy and Raman spectroscopy.

In this study, the production rate of both water-insoluble EPS, bacterial cellulose, and water-soluble EPS, P, was improved through сultivation of their producers on a nutrient media containing industrial wastes, and their material properties were analyzed. The growth rate and productivity of Gluconoacetobacter xylinus C3 strain on media with industrial wastes was investigated. An optimal nutrient medium based on molasses was selected for the bacterial cellulose producer. The nutrient medium contains 2% molasses, 1% yeast extract and peptone in a 1: 1 ratio, 0.3% sodium hydrogen phosphate, 0.1% citric acid and 1% ethanol. Cultivation of Gluconoacetobacter xylinus C3 strain on this medium for 7 days at 25–30 °С ensures its high productivity – 8.21 g/L. The composition of the optimized medium with molasses provides high mechanical properties (tensile strength – 37.12 MPa and relative elongation at break – 3.28%) of bacterial cellulose and does not affect the polymer microfibrillar structure. A modified Czapek-Dox medium with 10% molasses and 1% peptone is preferable for the exopolysaccharide accumulation by A. pullulans C8 strain. The optimized media has an advantage over the traditionally used media in terms of the efficiency of exopolysaccharide accumulation and cost reduction. The pullulan yield in media was 10.08 g/l, that is 1.5 times higher than in a standard Czapek-Dox medium. The surface morphology and microstructure of the pullulan samples obtained on different media showed minor changes. Therefore, the replacement of carbon source for molasses in a Czapek-Dox media for pullulan production did not alter the polymer content and viscosity.

Published: October 2019

How do we counter colonized schooling narratives in places where Indigenous identities and cultural ways of knowing have beensilenced? Based on encounters with children, the authors inquire into how cultural intersections can become pedagogical with the potential to disrupt colonizing narratives and explore Indigenous ways of knowing. They discuss inquiry’s emancipatory potential: granting space to listen, explore difference, think differently, and challenge the dominant colonizing discourses about Indigenous and Black children in early childhood settings.
Reconciliation as Relationship: Exploring Indigenous Cultures and Perspectives Through Stories
Authors: Motegi Natsuko
Published: October 2019

Responding to the calls to action of the Truth and Reconciliation Commission of Canada, a non-Indigenous author and her coeducator embarked on a learning and research journey with 4-year-old children in a preschool program. The challenge for the educators was to make the experience meaningful to the children rather than handing down a set of information on Indigenous cultures and history. Through exploring Indigenous stories, both the educators and the children shared their wonderings and coconstructed the meanings of them. Developing authentic appreciation toward Indigenous cultures and values through the power of stories became a first step toward reconciliation.

The overarching aim of this research is to empirically test the effect of customer experience on customer perceived value and behavioral intentions while assessing the mediating role of customer perceived value. To achieve this aim, we collect data from 338 customers of restaurants in South Korea. The hypotheses intended to achieve this aim are tested using the structural equations modeling technique. The outcome of the research reveals that customer experience positively and significantly affects behavioral intentions. Additionally, customer experience has a significant positive effect on both hedonic and utilitarian value respectively. Hedonic value positively and significantly predicts behavioral intents while utilitarian value is negative but significantly related to behavioral intentions. The study further finds support for a mediating effect of hedonic value on the relationship between customer experience and behavioral intentions. The current study provides managerial and theoretical insights into understanding customer experience management, customer perceived value, and customer behavioral intentions.
