The effects of rapid chilling and storage conditions on the quality of Brigitta Blue cultivar highbush blueberries (Vaccinium corymbosum L.)
Authors: Kozos Karolina , Ochmian Ireneusz , Chełpiński Piotr 
Published: April 2015

ABSTRACT
Controlled atmosphere storage allows for the long-term and short-term storage of fruit without a significant decrease in quality, resulting in a longer shelflife of fresh fruit. The Department of Horticulture at the West Pomeranian University of Technology in Szczecin conducted research on the effects of post-harvest precooling (3-4°C within two hours) and storage conditions (conventional cold room and controlled atmosphere storage) on fruit firmness, chemical composition, colour and weight loss.
After six weeks of storage, it was found that the quality of fruit had declined. In comparison with fresh fruit, the harvest was found to have lost weight and darkened in colour. In addition, a decrease in firmness and the content of ascorbic acid and polyphenolic compounds was also observed. The fruits that were stored in a cold room with a controlled atmosphere and rapidly chilled immediately after harvest were the least affected. In addition, the research showed that there was a high correlation between the anthocyanin index and the polyphenol content in the fruits. To maintain the high quality of the fruit, the fruit must be very rapidly cooled soon after harvest and stored under optimal conditions - a cold room with a controlled atmosphere.
The effects of PLA biodegradable and polypropylene nonwoven crop mulches on selected components of tomato grown in the field
Authors: Zawiska Izabela , Siwek Piotr 
Published: April 2015

ABSTRACT
The results of two years (2010-2011) of field studies using two types of nonwoven mulches (one biodegradable, polylactic acid PLA 54 g m-2, and traditional polypropylene PP 50 g m-2) on the yield and quality of tomato are presented. Seeds of tomato (‘Mundi’ F1) were sown in a greenhouse, in containers filled with perlite and sand, and then the plants at the cotyledon stage were replanted in multipot trays filled with substrate for vegetable plants. In the last week of May, seedlings were planted on mulches in the field at a spacing of 50 × 100 cm. The mulch was maintained throughout the growing season. A plot that remained unmulched served as the control. Tomatoes were harvested once a week. The fruits were evaluated for L-ascorbic acid, dry matter, soluble sugars and nitrate content. In 2011, the analysis of the plant material showed that the concentration of L-ascorbic acid was about 23% higher in the tomato fruits harvested from plants grown on biodegradable PLA 61 g m-2 mulch in comparison to the control. A similar effect was demonstrated for the soluble sugar concentration in 2011 for both types of nonwovens.
Brief functional analysis of repetitive verbal behavior (vocal stereotypy) for an adult with acquired brain injury
Authors: Strohmeier Craig , Stein Sorah , Cipani Ennio 
Published: April 2015

AbstractThe behavior analytic method of functional analysis (FA) is a process for identifying behavior-environment functional relations. Some research indicates the use of FA procedures to determine the environmental factors that maintain odd or inappropriate verbal behavior. The current study demonstrates the use of an FA to identify environmental influences on repetitive verbal behavior for an adult with acquired brain injury (ABI).A brief FA of repetitive verbal behavior was conducted in an outpatient program for individuals with ABI. Four conditions were alternated in a multielement single-case experimental design. Data were collected across conditions to determine if specific contextual variables differentially influenced the occurrence of repetitive verbal behavior.Data revealed increased occurrences of repetitive verbal behavior in a test condition that included contingent attention.Specific environmental factors were identified as sources of control for repetitive verbal behavior. The results of this case report support the use of FA for repetitive verbal behavior exhibited by individuals with ABI.
Coming to Understand Diversity and Education: Life Experiences and Educational Opportunities
Authors: Chamberlain Steven Paul 
Published: April 2015

Abstract
Coming to understand how cultural differences influence interactions between educators and students and their parents is a complex and perhaps life-long discovery. Culture helps to define groups’ belief systems and expectations for appropriate behavior, often at a hidden level. Pre-service teachers need multiple opportunities to interact with diverse populations in supervised and reflective environments. This article recounts key experiences in one White American’s life that have led to his current understanding of diversity and the role of diversity in education. These experiences occurred throughout my life; some were by chance and others were more prescribed. The article concludes with reflections on lessons learned as they pertain to teacher preparation programs.
Topical themes and thematic progression: the “picture” of research articles
Authors: Alvin Leong Ping 
Published: April 2015

AbstractAlthough much has been written about the features of academic writing, there is a lack of research attention on macro issues related to the development of ideas, particularly in the writing of research articles. A concept that is useful in investigating such issues is the Hallidayan notion of theme. However, the thematic structure of research articles has received only modest attention over the years. It is also rare for thematic diagrams to be used even though they can be helpful in clarifying the thematic structure of the text. In this exploratory study, the patterning of topical themes in research articles was investigated using a diagrammatic approach. Twenty biology-related research articles were divided into t-units and analyzed for topical themes. Thematic diagrams were generated for all the articles. The diagrams revealed a progressive thematic pattern in the introduction sections of all the articles. At the whole-text level, an anchored-development pattern was observed in the majority of the articles. These findings suggest that research articles at the macro level share similarities in their thematic structure. They also shed light on how authors achieve focus in the writing through the systematic use of clause-initial elements.
The Nagygate Affair, Corruption and Organized Crime: Corruption Networks and their Potential Impact on the Quality of Democracy in the Czech Republic
Authors: Kupka Petr , Mocht’ak Michal 
Published: April 2015

AbstractThis paper addresses the influence of organized crime on the performance of democracy in the Czech Republic and seeks to determine which dimensions of its political system (if any) are most endangered. We construe organized crime in terms of corruption networks, questioning in effect the predominant understanding of these two concepts as distinct or even exclusive phenomena. The paper thus construes corruption and organized crime as concepts referring to transgressive acts (i.e., behavior that involves a violation of moral or social boundaries that need not be legally codified), rather than in terms of legal norms. The influence of corruption networks is demonstrated using the “Nagygate” affair, which is analyzed using Maltz’s framework of potential harm. We argue that the debate on organized crime in the Czech Republic is, in fact, inherently tied to the study of corruption, since corruption constitutes an integral part of organized crime activity. Our findings are that transgressive behavior has a mostly negative impact, including loss of trust, the widespread belief that injustice goes unpunished, a weakening of the political system, and degeneration of the democratic regime. Moreover, the Nagygate scandal provides evidence that democratic institutions are not solely victims of organized crime but also a potential source of transgressive acts.
A study on AB2O6compounds, Part V: a DFT study on charge balance as driving force for structural organisation
Authors: Beck Horst P. 
Published: April 2015

AbstractIn continuation of earlier investigations on the structures of AB2O6compounds we have remodelled those with A=Ca, Sr, Ba and B=As, Sb, V, Nb, Ta by relaxation in DFT calculations with the VASP code. The results match the real structures very closely. We have then calculated charges of the constituent atoms by means of a Bader analysis of the calculated electron density distribution. The results of these calculations are discussed with the aim to establish a correlation between the charges of the atoms and the vicinity structure around the atoms. Similar calculations were done first for all these compounds in a rosiaite type structure and second for CaAs2O6in all the other structures found for these compounds. We discuss how the balance of charges changes on forcing the systems into another topology, and we finally address the issue that structural organisation is strongly determined by the need to balance charges of the constituting elements in their specific stoichiometric relation.
Using light to shape chemical gradients for parallel and automated analysis of chemotaxis

Published: April 2015

AbstractNumerous molecular components have been identified that regulate the directed migration of eukaryotic cells toward sources of chemoattractant. However, how the components of this system are wired together to coordinate multiple aspects of the response, such as directionality, speed, and sensitivity to stimulus, remains poorly understood. Here we developed a method to shape chemoattractant gradients optically and analyze cellular chemotaxis responses of hundreds of living cells per well in 96‐well format by measuring speed changes and directional accuracy. We then systematically characterized migration and chemotaxis phenotypes for 285 siRNA perturbations. A key finding was that the G‐protein Giα subunit selectively controls the direction of migration while the receptor and Gβ subunit proportionally control both speed and direction. Furthermore, we demonstrate that neutrophils chemotax persistently in response to gradients of fMLF but only transiently in response to gradients of ATP. The method we introduce is applicable for diverse chemical cues and systematic perturbations, can be used to measure multiple cell migration and signaling parameters, and is compatible with low‐ and high‐resolution fluorescence microscopy.
Fine-Tuning of the Actin Cytoskeleton and Cell Adhesion During Drosophila Development by the Unconventional Guanine Nucleotide Exchange Factors Myoblast City and Sponge
Authors: Biersmith Bridget , Wang Zong-Heng , Geisbrecht Erika R 
Published: April 2015

Abstract
The evolutionarily conserved Dock proteins function as unconventional guanine nucleotide exchange factors (GEFs). Upon binding to engulfment and cell motility (ELMO) proteins, Dock–ELMO complexes activate the Rho family of small GTPases to mediate a diverse array of biological processes, including cell motility, apoptotic cell clearance, and axon guidance. Overlapping expression patterns and functional redundancy among the 11 vertebrate Dock family members, which are subdivided into four families (Dock A, B, C, and D), complicate genetic analysis. In both vertebrate and invertebrate systems, the actin dynamics regulator, Rac, is the target GTPase of the Dock-A subfamily. However, it remains unclear whether Rac or Rap1 are the in vivo downstream GTPases of the Dock-B subfamily. Drosophila melanogaster is an excellent genetic model organism for understanding Dock protein function as its genome encodes one ortholog per subfamily: Myoblast city (Mbc; Dock A) and Sponge (Spg; Dock B). Here we show that the roles of Spg and Mbc are not redundant in the Drosophila somatic muscle or the dorsal vessel. Moreover, we confirm the in vivo role of Mbc upstream of Rac and provide evidence that Spg functions in concert with Rap1, possibly to regulate aspects of cell adhesion. Together these data show that Mbc and Spg can have different downstream GTPase targets. Our findings predict that the ability to regulate downstream GTPases is dependent on cellular context and allows for the fine-tuning of actin cytoskeletal or cell adhesion events in biological processes that undergo cell morphogenesis.
Organic/inorganic heterojunction based on conducting polymer and pulse-laser-deposited (PLD) ZnO
Authors: Wang Weining , Gutierrez Leandro , Nabizadeh Arya , Sahiner Mehmet A. 
Published: April 2015

ABSTRACTOrganic/inorganic heterojunctions have been fabricated by spin coating p-type poly (3, 4 ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT:PSS) onto n-type zinc oxide (ZnO) films. The ZnO films were deposited onto indium tin oxide (ITO) coated glass by pulse laser deposition (PLD) technique. The current density-voltage (J-V) characteristics of the PLD-ZnO/PEDOT:PSS junction based on as-deposited PLD-ZnO film shows a good rectifying behavior with a rectification ratio of 156 at ±1 V, indicating the formation of a diode between ZnO and PEDOT:PSS. Using thermionic emission model, the ideality factor (n=2.1) and barrier height (0.66 eV) of the heterojunction were obtained. Those diode parameters are better than those of the chemical vapor deposited ZnO/PEDOT:PSS heterojunction reported elsewhere, indicating that PLD may be a promising technique on fabricating high quality ZnO/polymer heterojunctions.

Published: April 2015

In May 2013, a scientific expedition was organized by the Vietnam Academy of Science and Technology and the Far Eastern Branch of the Russian Academy of Sciences (FEBRAS) in the frame of the VAST-FEBRAS International collaboration program. The expedition went along the coast of Vietnam from Quang Ninh to Kien Giang. The objective was to collect natural resources for investigation of the biological and biochemical diversity of the territorial waters of the Socialist Republic of Vietnam. Among the collected algae, six taxa are new records for the Vietnam algal flora. They are the red algae Titanophora pikeana (Dickie) Feldmann from Cu Lao Xanh Island, Laurencia natalensis Kylin from Tho Chu Island, and Coelothrix irregularis (Harvey) Børgesen from Con Dao Island, and the green algae Caulerpa oligophylla Montagne, Caulerpa andamanensis (Taylor, W. R., 1975) Draisma, Prudhomme et Sauvage from Phu Quy Island and Caulerpa falcifolia Harvey & Bailey from Ly Son Island. The seaweed flora of Vietnam now counts 833 marine algal taxa, including 415 Rhodophyta, 147 Phaeophyceae, 183 Chlorophyta and 88 Cyanobacteria.

Authors: Vinh Le Thi , Tam Pham Huu 
Published: April 2015

Analyzed results of 11 surface sediment samples collected in June 2012 in the south of Nha Trang bay showed that: The contents of the organic materials and heavy metals in the sediments were considerably various (organic C: 0.12 - 1.46% , organic N: 135.8 - 987.7 µg/g, total P: 44.0 - 551.1 µg/g; Zn: 2.2 - 28.7 µg/g; Cu: 2.6 - 22.2 µg/g, Pb: 2.7 - 28.1 µg/g, Fe: 514 - 17,337 µg/g) and correlated with the rate of mud fraction; Organic carbon and heavy metal contents tended to be higher in areas near Tre and Tam Islands and lower value in off - shore areas; Among studied areas: i) There was no significant difference in hydrocarbon content (from 115 - 188 µg/g); ii). Related to microbiology, coliform density (from 0 - 8,197 MPN/100g) was highest at Mieu and Mot Islands. Generally, the surface sediments in Nha Trang bay, in terms of organic materials and heavy metals, were suitable for the aquatic life. However, there was the lightly increasing trend in organic matters (N and P) from 2007 to 2012.
PROBABILISTIC SEISMIC HAZARD MAPS OF VIETNAM AND THE EAST VIETNAM SEA
Authors: Phuong Nguyen Hong , Truyen Pham The 
Published: April 2015

In this paper, the probabilistic seismic hazard maps for the territory of Vietnam and the East Vietnam Sea revised from the existing 2010 ones are presented. An earthquake catalog updated until 2014 and most recent seismotectonic and geodynamic information of South East Asia were used for delineation of 37 seismic source zones in the whole territory of Vietnam and the East Vietnam Sea area extended to 1250E. While the Toro et al. (1997) ground motion prediction equation was used for most seismic sources, the equation developed for the subduction zones by Youngs, Chiou, Silva and Humphrey (1997) was used for the Manila Trench source zone. The hazard maps show distribution of the mean peak ground acceleration (PGA) with 10%, 5%, 2% and 0.5% probability of exceedance in 50 years. The highest hazard areas were revealed in northwestern part of the country, in Dien Bien - Lai Chau and Son La source zones, with the maximum values of PGA for 475 - 9975 years of 180 - 272 gals; and off-shore Vietnam’s South Central coast, in the 1090Meridian Fault source zone, where the maximum values of PGA for 475 - 9975 years are 118 - 285 gals. These PGA maps present both short - term and long - term forecasts of seismic hazard in Vietnam and the East Vietnam Sea and can be used as a reference for antiseismic design and many engineering applications.
KANAK IMAGINARIES: A SENSE OF PLACE IN THE WORK OF DÉWÉ GÖRÖDÉ
Authors: Ramsay Raylene 
Published: April 2015

The study of the Kanak imaginary in the work of the first published Kanak (indigenous) New Caledonian writer shows this to be permeated by a sense of place. Rootedness in, and intense community with the land is not incompatible with the fluidity of ancestral criss-crossing of the Pacific or of constant border-crossing(pathways of exchange between groups) but nonetheless remains central. The ‘hinterland’ constituted by the places of the tribu (customary lands) sets up a challenge to the dominance ofNouméa la blanche and Déwé Görödé’s articulation of places of identity re-negotiate the urban/regional or Noumea/Bush/Tribu nexus to counterbalance or contest national (French) imaginaries. Yet Görödé’s work presents both a return to a Kanak Place to Stand and a critical self in process (the latter situated in a ‘no man’s land’). The places in her work are ultimately ‘cognitively dissonant’: the marginal or hinter-land of Kanak imaginaries (the tribu), can hold (to) their own both outside and inside the city yet also open themselves up internally to multiplicity and critique.
A PLACE TO STAND: LAND AND WATER IN MĀORI FILM
Authors: Walker-Morrison Deborah 
Published: April 2015

New Zealand (NZ) Māori identity, as is the case for indigenous peoples the world over, is inextricably linked to a sense of place of origin, Tūrangawaewae, literally, “a place to stand one’s feet.” Place here is obviously first and foremost about land, but also includes the rivers, lakes and sea that have sustained Māori communities since their arrival in Aotearoa, almost a thousand years ago. Linking representations of land and water to a re-reading of Paul Gilroy’s twin metaphors of roots and routes, this paper reads issues of loss, conservation, regaining and/or transformation of such a sense of place as central to Māori fiction film.
IMAGINING PLACE: AN EMPIRICAL STUDY OF HOW CULTURAL OUTSIDERS AND INSIDERS RECEIVE FICTIONAL REPRESENTATIONS OF PLACE IN CARYL FÉREY’S UTU
Authors: Carter Ellen 
Published: April 2015

I provide empirical evidence from a longitudinal cross-cultural reader reception survey showing that cultural outsider (French) and insider (New Zealand) readers are differently influenced by the geographically and culturally-situated elements in Utu (French 2004, English translation 2011), a crime novel set in contemporary New Zealand by French writer Caryl Férey. After reading the novel, both cultural outsider and insider readers changed their opinions towards the image portrayed by Férey, even when his cultural claims were incorrect. Furthermore, for French readers, this influence extended beyond Utu’s final page to opinions about New Zealand and its inhabitants.
HIGH-RISE ZHIVAGO
Authors: Siemens Elena 
Published: April 2015

This paper discusses the Taganka Theatre’s production of Pasternak’s Doctor Zhivago, staged in a remote Moscow suburb. Performed in a Soviet-built palace of culture, the show radically reinterpretsZhivago, transforming it from an intensely personal to a collective narrative. Drawing on a chapter from my book Theatre in Passing: A Moscow Photo-Diary (Intellect 2011), the paper refers to Marvin Carlson, who argues that theatre buildings and their locations greatly impact the overall meaning of a show. Citing evidence provided by cultural theorists, architectural critics, as well as authors and artists, I expand on my earlier discussion of suburbs – a fertile subject attracting a wealth of contradictory opinions. I illustrate my discussion with images of high-rises inspired by the avant-garde photographer Alexander Rodchenko, and pictures of soup cans and cases of Coca-Cola – my tribute to Andy Warhol, who, like Rodchenko, rejected the old in favour of the new. I conclude with a nostalgic shot of a single-family dwelling, reminiscent of the spaces depicted in Pasternak.
An Online, Moderated Peer-to-Peer Support Bulletin Board for Depression: User-Perceived Advantages and Disadvantages
Authors: Griffiths Kathleen Margaret , Reynolds Julia , Vassallo Sara 
Published: April 2015

Background
Online, peer-to-peer support groups for depression are common on the World Wide Web and there is some evidence of their effectiveness. However, little is known about the mechanisms by which Internet support groups (ISGs) might work.

Objective
This study aimed to investigate consumer perceptions of the benefits and disadvantages of online peer-to-peer support by undertaking a content analysis of the spontaneous posts on BlueBoard, a well-established, moderated, online depression bulletin board.

Methods
The research set comprised all posts on the board (n=3645) for each of 3 months selected at 4 monthly intervals over 2011. The data were analyzed using content analysis and multiple coders.

Results
A total of 586 relevant posts were identified, 453 (77.3%) reporting advantages and 133 (22.7%) reporting disadvantages. Positive personal change (335/453, 74.0%) and valued social interactions and support (296/453, 65.3%) emerged as perceived advantages. Other identified benefits were valued opportunities to disclose/express feelings or views (29/453, 6.4%) and advantages of the BlueBoard environment (45/453, 9.9%). Disadvantages were negative personal change (50/133, 37.6%), perceived disadvantages of board rules/moderation (42/133, 31.6%), unhelpful social interactions/contact with other members (40/133, 30.1%), and technical obstacles to using the board (14/133, 10.5%).

Conclusions
Consumers value the opportunity to participate in an online mutual support group for mental health concerns. Further research is required to better understand how and if these perceived advantages translate into positive outcomes for consumers, and whether the perceived disadvantages of such boards can be addressed without compromising the safety and positive outcomes of the board.
