The Creative Process. A Case for Meaning-Making
Authors: Setai Phokeng T. , Coetzee Jan K. , Maeder Christoph , Wojciechowska Magdalena , Ackermann Leane
Published: January 2019

Since the beginning of time art-making has been a tool to express, preserve, and challenge the extant knowledge in society. Artists do this by finding or creatively constructing new understandings in society. An artist is able to do this through the medium he/she uses to relay the message of the artwork. The medium that an artist uses to express his/her artistic concept has an impact on the character that the artwork will take. The medium of expression forms but one of the many considerations that go through an artist’s mind when creating art. In the process of art-making, an artist seeks to create new meanings or re-imagine old ones by organizing materials and concepts. In so doing, he/she discovers novel ways to get ideas across, and thereby creates new interpretations of social phenomena. In this article, attention is given to meaning-making as a conscious and iterative component of creating art. From a series of in-depth interviews, the authors analyze the inward processes that occur within six artists’ creative praxes and how these lead their construction of meaning. Attention is also paid to how the artists manipulate concepts and how they construct and deconstruct their understandings of these concepts in the course of their creative endeavors.
Online Social Networking, Interactions, and Relations: Students at the University of the Free State, Bloemfontein
Authors: Sele Sello J. , Coetzee Jan K. , Elliker Florian , Groenewald Cornie , Matebesi Sethulego Z.
Published: January 2019

Online social networking (OSN) is an activity performed through social network sites (SNS) such as Facebook, Twitter, WhatsApp, and Instagram. OSN has become a dominant interaction mechanism within contemporary society. Online platforms are woven inextricably into the fabric of individuals’ everyday lives, especially those of young adults. We present a mixed-methods study—conducted at the University of the Free State in Bloemfontein—that analyzes how students reflect on their everyday experiences of OSN. The key theoretical frameworks guiding this research are phenomenology, existentialism, and reflexive sociology. These theoretical lenses collectively assist in broadening our understanding of the students’ experiences that reveal the complexities associated with their interactions and social relations via SNS. From their narratives we learn how the students make sense of their engagements on SNS, how these engagements have an impact on their social interactions, and how OSN affects their self-presentation.
Experiencing Physical Disability: Young African Women in Lesotho
Authors: Rafoneke Seithati , Coetzee Jan K. , Bülow Pia H. , Jaffray Penny , Young-Hauser Amanda
Published: January 2019

The article unwraps notions related to young African women’s lifeworld experiences of physical disability. The study is positioned in the broad context of the theoretical frameworks of phenomenology, existential sociology, the social construction of reality, feminist disability theory, and intersectionality. Focus is given to the way social systems of cultural oppression and discrimination impact women with physical impairments and manifest in how they perceive and make meaning of their everyday life experiences. Women with physical impairments often experience a double measure of oppression—being both female and disabled. When these women try to engage in a normal life and interact with others, they experience barriers imposed on them by their social reality—particularly in the form of cultural norms and patriarchal ideals. There are also instances where participants demonstrate resilience in the face of negative social stereotyping, instances that clearly show that they are not different, and do not perceive themselves as being different to able-bodied women. Drawing on semi-structured in-depth interviews with eight young Black women who are living with physical disabilities in Lesotho, the objective of this article is to examine their everyday life experiences within a predominantly able-bodied society.

« Sauver l’imaginaire » : littérature et photographie face à face
Authors: Paigneau David
Published: January 2019

Si l’on peut définir, de la manière la plus générale, une oeuvre d’art comme ‘expression d’un imaginaire, cette définition posa le problème du statut de la photographie lors de son apparition : document purement objectif ou potentielle forme artistique. Écrivains et critiques littéraires prirent part à ce débat, d’autant plus que des photos furent utilisées pour illustrer des livres, notamment des romans, à partir des années 1880. Cet article tente de confronter « l’imaginaire littéraire » à « l’imaginaire photographique » à travers des points de vues d’écrivains, critiques, philosophes et médiologues, afin de tenter de mieux comprendre leurs points de convergence et de divergence.

Forms of Intimate Partner Rape Experienced by Latinas With and Without Posttraumatic Stress Disorder
Authors: Carey Emily T. , Galano Maria M. , Stein Sara F. , Clark Hannah M. , Grogan-Kaylor Andrew C. , Graham-Bermann Sandra A.
Published: January 2019

Intimate partner violence (IPV) affects a large proportion of women in the United States and is a serious public health concern. Rates of IPV are even higher for Latinas in the United States. Approximately, 10% of women experience intimate partner rape in their lifetime, and IPV and intimate partner rape have been strongly linked to the development of posttraumatic stress disorder (PTSD). However, little research has been done to distinguish different forms of intimate partner rape and their effects. This study examined intimate partner rape for 94 Spanish-speaking Latinas with and without a diagnosis of PTSD. Two forms of rape were assessed, physically forced rape and psychologically coerced rape, and 39% of the women were diagnosed with PTSD. A logistic regression (N = 62) was used to assess the relationship between PTSD and forms of rape. Results indicated that Latinas with PTSD reported more physically forced rape than Latinas without a diagnosis of PTSD. No significant difference in PTSD diagnosis was found for psychologically coerced rape. Future research should focus on investigating factors that potentially mediate the relationship between physically forced rape and PTSD.
A corporeidade da mulher Xavante: um movimento da cosmogonia
Authors: Rezende Maria Aparecida
Published: January 2019

O texto tem o objetivo de apresentar de modo sucinto a corporeidade e o movimento da cosmogonia das mulheres da aldeia Pimentel Barbosa. As protagonistas são as mulheres idosas que não conhecem a cultura escolar, mas são guardiãs da cultura do povo Xavante, no texto usando o nome que eles se autodenominam A’uwẽ uptabi (entendimento próximo por povo autêntico e verdadeiro). O questionamento maior é realizado pelas próprias mulheres quando perguntam – por que falam muito da festa dos homens A’uwẽ e não falam das mulheres? É comum leituras extensas em obras da antropologia, da linguística, educação, enfim, vários autores que pesquisaram esse povo fazem abordagens acerca dos rituais masculinos e não colocam as mulheres em evidências. A metodologia usada é parte da tese doutoral, em que o enfoque são elas, mas também informações obtidas por meio das conversas informais e vivências com essas mulheres em outros momentos que não são de pesquisas. As fontes advêm do universo da fenomenologia, Merleau-Ponty (2009, 2006), Freire, Astrain e outros autores. O resultado da discussão é o debate de como tem caminhado a questão do diálogo entre povos indígenas e não indígenas no sentido de interculturalidade; como vive esse povo em meio ao contexto cultural de contato não indígena. Assim, o texto vai se desenhando e fazendo uma pintura em paisagem colorida mostrando o universo dessas mulheres, sua relação com o mundo cósmico e com o mundo ocidental.
Violência epistêmica e a invenção do outro na narrativa “O Pajé de Cristo”, de Homer Dowdy
Authors: Câncio Raimundo Nonato de Pádua , Araújo Sônia Maria da Silva
Published: January 2019

O pensamento materializado na forma de escritos é um importante recurso para disseminação de valores, conhecimentos e ideologias. A obra “O Pajé de Cristo”, de Homer Dowdy, narra o processo de conversão dos povos indígenas Wai-wai ao cristianismo evangélico pelos missionários norte-americanos, o que se dá por meio da descrição de práticas educativas de catequização, fundamentadas na lógica da dominação e da superioridade epistêmica. O principal objetivo deste estudo é identificar as estratégias persuasivas utilizadas pelo autor-narrador para convencer o leitor de que o processo de conversão dos povos Wai-wai ao cristianismo evangélico foi necessário, mesmo num contexto em que conhecimentos e valores se explicam e se confrontam. Como referência, apresentamos algumas aproximações entre a corrente teórica Pós-Colonial e a perspectiva Decolonial, no que toca à crítica epistemológica, sobretudo para questionar o discurso imperialista norte-americano, engendrado pelos missionários evangélicos. O resultado deste estudo tem sido a necessidade de reinterpretação e de reescrita das narrativas sobre os povos indígenas da Amazônia como resposta ao colonizador.
Tembiasakue Rapê: a longa estrada Guarani na história e na memória- reconstruindo o passado, ressignificando o presente e trilhando o futuro.
Authors: Ivarra Ortiz Rosalvo , Machado Almires Martins
Published: January 2019

Ao longo dos séculos o Guarani foi visto como objeto de estudo e do direito, sendo-lhe negada a característica de agente de sua própria memória/história/narrativa, como protagonista dinâmico, ativo e consequentemente sem espaço para manifestar-se, era o indígena domesticado sobressaindo à imagem genérica construída pelo senso comum ao longo da trágica história que todos já conhecem. Entretanto, assim como os demais seres humanos que habitam a imensidão do planeta terra, enquanto indígenas temos o passado bem vivo na nossa memória e na a capacidade de reconstituir o nosso passado; nosso futuro depende muito da habilidade de compreender e tirar boas lições do que nos aconteceu em outrora. O passado é relembrado por meio das narrativas na fala dos tujá’i (velhinhos), contadores de história Guarani. Conhecimento que é transmitido nas conversas na opy(casa ritual), na beira do fogo quando dos acampamentos de pescaria, caçadas ou ainda nos momentos em que seus olhos e alma parecem voltar no tempo e as narrativas fluem como as águas de um igarapé, adentrando a noite. Para que nosso modo de vida percorra outros modos de narrar o passado e o presente, busca-se a qualificação nos meios acadêmicos, uma abrangência maior de conhecimento enquanto sociedade Guarani e as interações com a sociedade não indígena, engendrando novos conceitos, experiências interpretativas sobre o outro e o que foi dito sobre nós de forma autoritária e violento. É uma tentativa de compreender, traduzir e a posteriori interpretar, para conhecerem-se melhor ambas as sociedades e ampliar os horizontes de conhecimentos e possibilidades, sabendo de antemão que essas aproximações humanas não são tão tranquilas quanto parecem ser. Ser mediador dessa realidade não é nada fácil, ou seja, é um grande desafio.
Derivation of generalized Einstein's equations of gravitation based on a mechanical model of vacuum and a sink flow model of particles
Authors: Wang Xiao-Song
Published: January 2019

J. C. Maxwell, B. Riemann and H. Poincaré have proposed the idea that all microscopic particles are sink flows in a fluidic aether. Following this research program, a previous theory of gravitation based on a mechanical model of vacuum and a sink flow model of particles is generalized by methods of special relativistic continuum mechanics. In inertial coordinate systems, we construct a tensorial potential which satisfies the wave equation. Inspired by the equation of motion of a test particle, a definition of a metric tensor of a Riemannian spacetime is introduced. Applying Fock's theorem, a generalized Einstein's equation in inertial systems is derived based on some assumptions. This equation reduces to Einstein's equation in case of weak field in harmonic coordinate systems. In some special non-inertial coordinate systems, a second generalized Einstein's equation is derived based on some assumptions. If the field is weak and the coordinate system is quasi-inertial and harmonic, the second generalized Einstein's equation reduces to Einstein's equation. Thus, this theory may also explains all the experiments which support the theory of general relativity. There exists some fundamental differences between this theory and Einstein's theory of general relativity.
World Turned Upside Down: Entrepreneurial Decline, Its Reluctant Myths and Troubling Realities
Authors: Cooke Philip
Published: January 2019

The aim of this paper is to attempt to understand why the popular academic and policy field of promoting, studying and evangelising “entrepreneurship” should have been associated with great success but, in the past twenty years or more in many advanced economies, so much failure. From the US to lesser and developing countries, emerging economies and the European Union, entrepreneurship, especially in regard to start-ups and particularly high-tech start-ups have been in constant more or less recent decline. This is seldom registered in the mainstream literature where a positive and benign profile is generally presented. The paper examines this phenomenon, ties it partly with the “productivity paradox” and seeks tentative hypotheses in relation to the apparent illusions if not delusions regarding “entrepreneurship”.
Control Upstream Austenite Grain Coarsening during Thin Slab Casting Direct Rolling (TSCDR) Process
Authors: Zhou Tihe , O'Malley Ronald J. , Zurob Hatem S. , Subramanian Mani , Cho Sang-Hyun , Zhang Peng
Published: January 2019

Thin Slab Casting and Directing Rolling (TSCDR) has become a major process for flat- rolled production. However, the elimination of slab reheating and limited number of thermomechanical deformation passes leave fewer opportunities for austenite grain refinement resulting in some large grains persist in the final microstructure. In order to achieve excellent Ductile to Brittle Transaction (DBTT) and Drop Weight Tear Test (DWTT) properties in thicker gauge high strength low alloy products, it is necessary to control austenite grain coarsening prior to the onset of thermomechanical processing. This contribution proposes a suite of methods to refine the austenite grain from both theoretical and practical perspective including: increasing cooling rate during casting, liquid core reduction, increasing austenite nucleation sites during the delta ferrite to austenite phase transformation, controlling holding furnace temperature and time to avoid austenite coarsening, and producing new alloy with two phase pinning to arrest grain coarsening. These methodologies can not only refine austenite grain size in the slab center, but also improve the slab homogeneity.
Computational Characterization of the mtORF of Pocilloporid Corals: Insights into Differences in Protein Structure and Function among Stylophora Lineages from Contrasting Environments
Authors: Banguera-Hinestroza Eulalia , Sawall Yvonne , Flot Jean-François
Published: January 2019

More than a decade ago, a new mitochondrial Open Reading Frame (mtORF) was discovered in corals of the family Pocilloporidae, which turn out to be an effective barcode gene for these corals. However, its function remains unknown. Recently, this gene revealed the existence of a hybrid Stylophora lineage (RS_LinA) inhabiting in sympatry along the environmental gradient of the Red Sea (18.5°C to 33.9°C) with its parental species (RS_LinB). Furthermore, in RS_LinB, the mtORF uncovered phylogeographic patterns that were strongly correlated with environmental variations. This was similar to the patterns unraveled by hsp70, suggesting that mtORF too might be involved in thermal adaptation. Here we used computational approaches to characterize the mtORF and to identify its potential role. Results showed that this gene encodes a transmembrane protein (0.97<P< 1.00) involved in transport (0.80<P< 0.87), regulation of metabolic processes (0.70<P<0.85), and likely in the cell-surface receptor signaling pathway (0.56<P<0.80). Predicted protein functions differed among Stylophora lineages and interestingly, in RS_LinB only, the protein was intrinsically disordered and displayed domains involved in cellular complexes and stress response (0.0001< P <0.001). These characteristics, exclusive of an endemic lineage adapted to extreme environmental fluctuations, support a role of the mtORF in stress response, speciation and adaptation.
Hybrid 3D Models: When Geomatics Innovations Meet Extensive Built Heritage Complexes
Authors: Chiabrando Filiberto , Sammartano Giulia , Spanò Antonia , Spreafico Alessandra
Published: January 2019

This article proposes the use of a multi-scale and multi-sensor approach to collect and modelling 3D data concerning wide and complex areas in order to obtain a variety of metric information in the same 3D archive, based on a single coordinate system. The employment of these 3D georeferenced products is multifaceted and the fusion or integration among different sensors data, scales and resolutions is promising and could be useful for the generation of a model that could be defined as hybrid. The correct geometry, accuracy, radiometry and weight of the data models are hereby evaluated comparing integrated processes and results from Terrestrial Laser Scanner (TLS), Mobile Mapping System (MMS), Unmanned Aerial Vehicle (UAV), terrestrial photogrammetry, using Total Station (TS) and Global Navigation Satellite System (GNSS) as topographic survey. The entire analysis underlines the potentiality of the integration and fusion of different solutions and is a crucial part of the “Torino 1911” project whose main purpose is mapping and virtually reconstructing the 1911 Great Exhibition settled in the Valentino Park in Turin (Italy).
The DOAJ Spring Cleaning 2016 and What Was Removed – Tragic Loss or Good Riddance?
Authors: Frantsvåg Jan Erik
Published: January 2019

In December 2012, DOAJ’s parent company, IS4OA, announced they would introduce new criteria for inclusion in DOAJ [1] and that DOAJ would collect vastly more information from journals as part of the accreditation process – and that journals already included, would need to reapply in order to be kept in the registry. My hypothesis was that the journals removed from DOAJ on May 9th 2016 would chiefly be journals from small publishers (mostly single journal publishers) and that DOAJ journal metadata information would reveal that they were journals with a lower level of publishing competence than those that would remain in the DOAJ. Among indicators of publishing competence could be the use of APCs, permanent article identifiers, journal licenses, article level metadata deposited with DOAJ, archiving policy/solutions and/or having a policy in SHERPA/RoMEO. The analysis shows my concerns to be correct.
A Method to Encourage Minimum Reporting Guideline Uptake for Data Analysis in Metabolomics
Authors: Considine Elizabeth C. , Salek Reza M.
Published: January 2019

Despite the proposal of minimum reporting guidelines for metabolomics over a decade ago, reporting on the data analysis step in metabolomics has been shown to be unclear and incomplete with major omissions and lack of logical flow rendering the data analysis’ workflows in these studies impossible to follow and therefore replicate or even imitate. Here we propose possible reasons why the original guidelines have had poor adherence and present an approach to improve their uptake. We present in this paper an R markdown reporting template file that guides the production of text and generates workflow diagrams based on user input.  This R Markdown template contains, as an example in this instance, a set of minimum information requirements specifically for the data pre-treatment and data analysis section of biomarker discovery metabolomics studies, (gleaned directly from the original proposed guidelines by Goodacre at al.). These minimum requirements are presented in the format of a questionnaire checklist in an R markdown template file. The R Markdown reporting template proposed here can be presented as a starting point to encourage the data analysis section of a metabolomics manuscript to have a more logical and stepwise presentation and to contain enough information to be understandable and reusable. The idea is that these guidelines would open to user feedback, modification and updating by the metabolomics community via GitHub. 
Hidden Reason of Paint System Delamination
Authors: Królikowska Agnieszka , Komorowski Leszek , Bonora Pier Luigi
Published: January 2019

In many instances paints interlayers delamination is attributed either to environmental or to application reasons. The composition as well as the structure, including morphology are always given for granted. Extended interlayer delamination was observed on two huge structures (>50000m2 each) causing more than $10 M damages. Overcoating time, UV exposure, Solvent retention and other possible environmental possible causes were considered. However, a careful morphological analysis showed that substantial differences existed in terms of the resin to pigment ratio, the surfactants, the quality of pigments and fillers (dimensions, shape, wettability, reactivity, homogeneity of distribution…) with respect to the sample used to certify suitability of the systems to climatic conditions C4 – C5 (ISO12944). The need to avoid any either voluntary or casual modification in both PVC and the kind and size of pigments to be used should be made evident as well as shown in some paragraph of existing Standards.
Multiple-Layer Microperforated Panels as Sound Absorbers in Buildings: A Review
Authors: Cobo Pedro , Simón Francisco
Published: January 2019

Sound absorbing materials are used in building to dissipate sound energy into heat by viscous and thermal processes. Sound absorbers increase the transmission loss of walls, decrease the reverberation time of rooms and attenuate the noise generated by internal sound sources. Porous absorbers (fibrous, cellular or granular) are the most used materials in noise control applications, since their high performance-to-cost ratio in the frequency band of interest. However, when cleaning and health reasons are of concern, microperforated panel (MPP) absorbers can be preferred. MPPs, consisting of many minute (sub-millimetric) holes in a panel, are tunable absorbers in a prescribed frequency band, which main shortcomings are high manufacturing cost and limited absorption frequency band. Production cost of MPP can nowadays be drastically cut down by means of modern techniques. Absorption frequency band can be considerably enlarged by designing multiple-layer MPPs (ML-MPPs). The aim of this article is to review the high potential of ML-MPPs as a modern, clean and healthy alternative of porous materials for sound absorption.

“Integrated Study on Mitigation of Multimodal Disasters Caused by Ejection of Volcanic Products” Project was launched in March 2014 for the Galunggung, Guntur, Kelud, Merapi, and Semeru volcanoes. The objectives of the project include the development of an observational system for the prediction and real-time estimations of the discharge rate of volcanic products. Under the project, a team from the Sakurajima Volcano Research Center, Center for Volcanology and Geological Hazard Mitigation (CVGHM) and the Balai Penyelidikan dan Pengembangan Teknologi Kebencanaan Geologi (BPPTKG) initiated the installation of a digital seismic and global navigation satellite system (GNSS) observational network for the volcanoes in December 2014, and finished the installation in September 2015. The seismic and GNSS data are transmitted by wireless local area networks (WLANs) from the stations to an observatory at each target volcano. We introduced three Windows PC software for data analysis: the first for estimating the equivalent rate of ejected ash from a volcano, the second for continuous smoothing of tilt data and detecting inflation and deflation in the volcanic sources, and the third for continuously evaluating eruption urgency to predict the eruption time. The seismic and GNSS data were routinely transmitted to the Support Systems of Decision Making (SSDM) at CVGHM or BPPTKG. Data completeness varied from volcano to volcano; for example, the data acquired for Kelud volcano were relatively stable, while those for Merapi volcano were problematic, owing to a communication disruption in the WLAN. We obtained the seismic and GNSS data at the target volcanoes in the observation period since 2015 when they have been relatively quiet.

Merapi, the dangerous active volcano in Indonesia, has been monitored since the 1920s by applying several methods and tools. The monitoring data from earlier times are stored well and can be used as reference for any precursors and signs before each eruption. This article evaluates the long-term activity of Merapi from the monitoring data for 1992–2011 to obtain the trends and patterns before the eruption period by combining the seismicity, deformation, volcanic gas, and temperature data in the same time span. Several characteristics are exhibited before effusive and explosive eruptions, i.e., a significant level up in volcano-tectonic energy and increased CO2gas concentration indicating an explosive eruption. Effusive eruption is characterized by a significant multiphase earthquake with less occurrence of deep and shallow volcano-tectonic events. Deformation data from a tiltmeter and electronic distance measurement are important in understanding the dynamics of the lava dome and the eruption direction.
Estimating the Volcanic Ash Fall Rate from the Mount Sinabung Eruption on February 19, 2018 Using Weather Radar

This paper presents a theoretical method for estimating volcanic ash fall rate from the eruption of Sinabung Volcano on February 19, 2018 using an X-band multi-parameter radar (X-MP radar). The X-MP radar was run in a sectoral range height indicator (SRHI) scan mode for 6° angular range (azimuth of 221°–226°) and at an elevation angle of 7° to 40° angular range. The distance of the radar is approximately 8 km in the Southeastern direction of the vent of Mount Sinabung. Based on a three-dimensional (3-D) image of the radar reflectivity factor, the ash column height was established to be more than 7.7 km, and in-depth information on detectable tephra could be obtained. This paper aims to present the microphysical parameters of volcanic ash measured by X-MP radar, which are the tephra concentration and the fall-out rate. These parameters were calculated in a two-step stepwise approach microphysical model using the scaled gamma distribution. The first step was ash classification based on a set of training data on synthetic ash and its estimated reflectivity factor. Using a naïve Bayesian classification, the measured reflectivity factors from the eruption were classified into the classification model. The second step was estimating the volcanic ash concentration and the fall-out rate by power-law function. The model estimated a maximum of approximately 12.9 g·m-3of ash concentration from the coarse ash class (mean diameterDn= 0.1 mm) and a minimum of approximately 0.8 megatons of volcanic ash mass accumulation from the eruption.

The relationship between market orientation and firm performance have been explored from a several researchers. Even so, there is a gap that can be developed from that relationship, especially if associated with the firm performance measured. This study aims to explore the relationship between market orientation and marketing performance with product innovation as a mediating variable. The data collected from 150 respondents with purposive sampling technique. The results showed that there is a positive relationship between market orientation and all of marketing performance measurement. Furthermore, the study also found that product innovation is mediating the relationship between market orientation and marketing performance. The implications of the research findings have been discussed and there are some recommendations for the future researchers.

Authors: Anggraini Anggi Ratna
Published: January 2019

This research focuses on the dilemma of small Public Accounting Firms in maintaining their survival, but still maintaining their audit quality. This research is qualitative research with interpretive paradigm and the case study method. This study shows how Public Accounting Firm X faces a dilemma situation when auditing small clients with low fees, while maintaining their audit quality. Public Accounting Firm X in its survival growth strategy uses a "zebra", a "radar" and a business diamond strategy. Public Accounting Firm X itself has a dilemma when faced with a small client who can only pay a low fee for audit services, if using the indicator minimum hourly charge-out rates determined by IAPI, then the audit fee cannot be applied on the client. In the end, the audit procedures carried out must be adequate to maintain audit quality, where Public Accounting Firm X uses Excel based Standard Working Paper during audits and cuts the leveling level. Regulations that accommodate more smaller clients in the area are needed related to audit services.
In Vitro Ranking of Salinity Tolerance in Potato (Solanum sp.)
Authors: Khrais T. , Donnelly D.
Published: January 2019

Globally, salinization of agricultural soils is an increasing problem. At least 25% of the world's cultivated land area is now salt-affected. Although the potato (Solanum tuberosum L.) is among the most important of crops plants, little is known of the range of salt tolerance among cultivars of S. tuberosum, wild Solanum sp., or their hybrids. The objective of this work was to rank the salinity (NaCl) tolerance of 200 North American and European cultivars, 13 hybrids of S. chacoense, S. tuberosum, and primitive cultivated diploids (S. phureja and/or S. stenotomum) and their progenies, and 14 accessions of S. chacoense from different collection sites. This was done in vitro, using a modified nodal cutting bioassay. The parameters evaluated included shoot and root lengths, and fresh and dry weights. Extreme variation for salinity tolerance was noted among the cultivars, the hybrids, and the wild species.
Foliar and Soil Zn Applications Increase Yield of Grapefruit Trees
Authors: Swietlik Dariusz
Published: January 2019

The effects of soil and foliar Zn applications on growth, yield, and fruit quality of `Rio Red' grapefruit were studied in the field for 4 years. Two annual foliar sprays applied in winter (W), spring (S), or W+S were compared to a single application of 10 or 30 g of Zn/tree applied to the soil around the tree as ZnDTPA or ZnEDTA chelate. In the first 2 years, when control trees displayed severe Zn deficiency symptoms affecting 60% to 70% of the tree foliage, the W and W+S sprays resulted in significant yield increases. Similar yield increases were obtained after a single soil application of 30 g Zn as ZnEDTA. The effects of other soil treatments were statistically insignificant. Foliar Zn deficiency symptoms were much more severe in winter than summer months irrespective of treatment. As the trees aged, however, the severity of symptoms decreased in all treatments. Corrective foliar or soil Zn applications were found to increase grapefruit yield when 15% or more of the canopy foliage showed Zn deficiency symptoms in January, ≈2 months before anthesis.
Weather Parameters Affecting Dry Bean Yields in Western Nebraska
Authors: Nuland D.S. , Taylor R.G.
Published: January 2019

A phenological approach was used to test the effect of weather parameters upon yield of dry beans. A time series (1940 to present), cross-section of western Nebraska bean-growing counties coupled with weather variables taken from respective weather stations was used to estimate regression equations. Weather parameters in context of the phenological development of the dry bean were tested in predicting yields. Analysis of the error was used to explain unique historical events that impact yield outside of weather. The predictive ability of the equation can then be used by producers, Ag. Lenders, and other industry personnel to predict yield and thus total production for the western Nebraska dry bean industry.

Published: January 2019

Little research has been conducted to quantify allelopathic suppression of weeds in the field. The objectives of this study were to develop an adequate control for separating physical from allelochemical effects, use the control to quantify allelochemical suppression in the field, and determine whether a mixture of cover crops would provide a broader spectrum of weed control than single species. Hairy vetch, rye, crimson clover, and barley were cut into 5-cm pieces, shaken in distilled water (pH 6) to leach allelochemicals, and redried. A seed germination bioassay confirmed that leached cover crops were nontoxic to germinating seeds. Physical suppression of Eastern black nightshade by the four cover crop species occurred in the field study, as did allelochemical suppression by crimson clover. Only rye physically suppressed yellow foxtail, and none of the cover crops suppressed yellow foxtail allelochemically.
Sugars and Respiration Profiles in Asparagus Spears and Changes during Storage
Authors: Silva Silvanda , Verlinden Sven , Herner Robert , Beaudry Randolph
Published: January 2019

Base-to-tip profiles of sucrose, glucose, fructose, and respiration rate were measured for asparagus (Asparagus officinalis L.) spears stored at 0C. Fructose content was ≈3-fold and 4-fold higher than glucose and sucrose, respectively. The highest level of fructose was found in the base and was ≈15-fold higher than the tip. The changes in asparagus metabolism were characterized by loss of sucrose and a high rate of respiration within the first hours after harvest. Sucrose was more rapidly lost than the other sugars during this period. The respiration rate was measured along the length of intact spears at 0.5, 1, 2, and 3 h after harvest. Subsequent measurements were taken after larger time intervals for 23 days. The respiration rate declined rapidly to ≈60% of the initial rate within 12 h, decreasing more slowly thereafter. Initially, the respiration rate of the tip was about four times that of the base, but, after 23 days, the respiration rate of the tip was only twice that of the base. Sucrose content and respiration rates were closely correlated.
Preconditioning Effects of Proliferation Medium on Adventitious Regeneration of Pear
Authors: Bell Richard L.
Published: January 2019

Preconditioning effects of cytokinin in the shoot proliferation medium on explant quality and subsequent adventitious regeneration of `Bartlett' and `Beurre Bosc' pear were investigated. The basal medium for regeneration consisted of half-strength MS macro- and micronutrients, MS organics, 30 g·liter–1 sucrose, 6 g·liter–1 agar, and 10 μM thidiazuron (TDZ), and 1 μM NAA. Leaves from BAP medium were more effective than those from media with 2-iP or kinetin in spite of the increased leaf size of shoots cultured with 2-iP (28% vs. 10%). Use of leaves from in vitro-rooted shoots did not increase regeneration frequency (19.5% vs. 31%) of `Bartlett'. Actively expanding leaves are more suitable explants than larger, fully expanded leaves. Liquid medium overlays and incubation in liquid medium decreased regeneration frequency when compared with agar-solidified medium. Among auxins in regeneration induction phase media, IBA (0.5 or 1.0 μM) resulted in greater regeneration than NAA.
Seedling Reaction of Prunus Accessions to Crown Gall
Authors: Almehdi Ali A. , Bliss F.A.
Published: January 2019

Crown gall incited by Agrobacterium tumifaciens is an important problem for nursery and field production of stone fruit and nut crops. Genotypes reportedly differ for crown gall reaction, but there is little information about resistance of Prunus accessions used as rootstocks. From among four wild-type strains of A. tumifaciens-virulent on apricot and almond, K12 was selected for inoculation of 6-month-old seedlings of cherry, plum, peach, almond, apricot, and miscellaneous species. The large majority of seedlings were very susceptible to crown gall, but some had few or no galls. Cherry, especially some lines of P. mahaleb, showed the most resistant or moderately resistant seedlings, while some accessions of plum, especially P. cerasifera, P. angustifolia, and P. insititia had the most resistant seedlings. Plants with different reactions were propagated to determine adult plant resistance and to study the heritability of crown gall reaction.
Feasibility of Using Saline Drainage Water for Processing-tomato Irrigation
Authors: Mitchell J.P. , May D.M. , Shennan C.
Published: January 2019

Field studies were conducted in 1992 and 1993 to assess the effects of irrigation with saline drainage water on processing-tomato fruit yields and quality constituents. Saline water (ECiw = 7 dS/m) was used for 66% of the seasonal irrigation requirements in 1992 and 82% in 1993. Yields of tomatoes irrigated with saline water were maintained relative to nonsaline irrigation in 1992, but were decreased by 33% in 1993. Juice Brix and Bostwick consistency were generally improved by irrigation with saline water. pH was unaffected by irrigation treatment, and titratable acidity, an estimate of citric acid content, was increased only in 1993. Calculated quantities for various marketable processed product yields reflect the dominant influence of fresh fruit yield that masked, to a large extent, whatever quality enhancements that may have derived from saline irrigation. The substantial tomato yield reduction that occurred in the second year of this study in plots irrigated with saline drainage water, the gradual surface accumulation of boron, as well as the significant salt buildup in lower portions of the crop root zone following drainage water irrigations demonstrate definitive limitations to the reuse approach and restrict options for the crops that can be grown in this system and the frequency of saline drainage reuse.
