Bayesian Geographical Multi-Dimensional Scaling
Authors: Nishi Hayato , Asami Yasushi
Published: July 2019

Abstract. Multi-dimensional scaling (MDS) is a popular method of visualizing the similarity of individuals in a dataset. When dissimilarities between individuals in a dataset are measured, MDS projects these individuals into the (typically two- or three-dimensional) map. In this map, because similar individuals are projected to be close to one another, distances between individuals correspond to their dissimilarities. In other words, MDS makes a similarity map of a dataset.Some of the dissimilarities and distances have a strong relation to the geographical location. For example, time distances are similar to geographical distances, and regional features will be similar if the regions are close together. Therefore, it will be useful to compare the MDS projection and geographical locations. However, because MDS projection is not concerned with the rotation, parallel translation, and similarity expansion, it might be difficult to compare the projection to the actual geographical locations. When geographically related similarities are visualized, projected locations should be bound to the geographical locations.In this article, we propose Bayesian Geographical Multidimensional Scaling (BGMDS), in which geographical restrictions of projections are given from a statistical point of view. BGMDS gives not only geographically bound projections, but also incorporates the uncertainty of the projections.
1/30 scale of Japan topography model realized with Minecraft
Authors: Nishioka Yoshiharu
Published: July 2019

Abstract. The purpose of this research is to provide an environment for children to learn about Japan's topography. In recent years, games have been attracting attention as tools for active learning, which has been a departure from conventional knowledge acquisition bias education. I focused on 3D sandbox game called Minecraft (Mojang/Microsoft) which is popular among children. In Minecraft, players can freely move in the 3D world and create buildings. Minecraft can reproduce 3D topography and simulate it, so it has high potential as a geography and geology education.I have created 1/30 scale of Japanese terrain model for Minecraft Java 1.12.2. The created data can be downloaded and used freely. The usage method is simple, it only copies it to the prescribed directory of the environment where Minecraft was installed.For the elevation data necessary for model creation, I use the elevation tile released by the Geospatial Information Authority of Japan as open Data. This elevation tile covers the whole of Japan with 10m mesh accuracy. This elevation tile is an application of the tiled map image often used in Web maps to data representation. I call such a data set “Data Tile Map”. Each pixel holds the elevation as a signed integer in cm units, using 24-bit RGB values.The creation program is written in JavaScript and can be executed in an environment with a web browser. With the creation program you can change the output resolution (zoom level) and vertical direction exaggeration ratio. In the future, I plan to add functions to correspond to the terrain of the world and create data by specifying the area.
Creation and analysis of a GIS land-use map for the end of the Edo period in Tokyo
Authors: Noma Takeshi
Published: July 2019

Abstract. The Meiji Restoration marks its 150th anniversary in 2018. This historical event memorializes the transition between the Tokugawa shogunate system and the Meiji government, a turning point in the modernization of Tokyo. In such an anniversary year, it is important to look back on the history of Tokyo, a city of global significance.Urban development in Tokyo has been commented on from various perspectives by Jinnai (1992), Maki (1980), Okamoto (2017), and others. However, few studies have followed quantitative changes to the city using GIS. In this study, a land-use map of Tokyo at the end of the Edo period was made as a GIS date. Using this map, we analyzed how land was used in the city during the Edo period; in the future we will quantitatively analyze land-use change up to the present.To create land-use maps, we first projected a paper map, the “restored Edo information map (geometrically corrected),” onto ArcGIS, and overlaid a 20-m mesh on top of it. Then, by manually inputting the attributes of each mesh, the map of Figure 1 was completed.Figure 2 shows the percentage of each land use based on the created land-use map. While more than 60% of the area comprised samurai residences, 14% was occupied by townspeople, even though townspeople accounted for more than half of the population. In addition, correlation with topographical data created using “the Digital Map 25000 (Land Condition)” shows the following. The upper-class samurai lived in comfort on the plateaus, while lower-class townspeople typically lived in the lowlands. The samurai used the sloping land of the plateau in characteristic ways. They built mansions at its edge, creating gardens that utilized springs flowing from the cliffs. In many cases, temples or shrines were located at one end of the valley so that these religious structures served as the boundary between the samurai and the townspeople.As has been noted, land use in the Edo period was characterized by a profusion of samurai residences. Additionally, land was used differently depending on topography. These results were quantitatively and comprehensively reached using GIS. Further, by using the same method to create land-use maps after the Meiji Restoration, we see that land-use change can be followed mechanically on GIS.
Plain cartography – web maps for visually impaired and elderly people
Authors: Oksanen Juha , Kettunen Pyry , Koski Christian
Published: July 2019

Abstract. Governmental services are being digitalized rapidly, and many European countries are currently implementing their eGovernance strategies. Although digitalization in general lowers the barriers between governance and citizens, there is also a significant risk that where a section of citizens is concerned, the barriers actually get higher. eGovernment services rely mostly on visual user interfaces, but globally approximately 1.3 billion people have some form of visual impairment. Furthermore, societies around the world will face the challenge of demographic transition, where most people are expected to live longer than 60 years and by 2080 almost 30% of the EU-28 population may be over the age of 65.In our study, we propose a complementary approach to the Web Content Accessibility Guidelines 2.0 for accessible spatial communication, where the content of web maps is optimized for people with abnormal eyesight and possibly degraded cognition. By defining plain cartography, we set the design principles for simplified digital maps (Figure 1) by taking how maps are seen into account and how they are understood by these special groups.We demonstrate the implementation of design principles in the Plain Map series produced by the National Land Survey of Finland and summarize the results of a usability test. Based on these results, the need of plain cartography for the visually impaired is high. In general, the feedback of the Plain Map series was very positive, and maps designed with increased clarity and high-contrast colors were seen much better than regular background maps. The implementation of the presented principles for generating plain map series is a small effort for National Mapping Authorities (NMAs), but it has an enormous impact through the improved accessibility of background maps in eGovernment services.
The Application Programmer Interface (API) in Modern Cartography: Development and Prospects
Authors: Peterson Michael P.
Published: July 2019

Abstract. Application Programmer Interfaces have been a part of the cartographic landscape since 2006 with the introduction of the Google Maps API. Essentially a library of code that provides access to a variety of mapping functions, APIs have since been the basis of online, tile-based, Multiscale Pannable (MSP) mapping. While the Google Maps API is still the most widely used with more than 4.6 billion websites embedding a Google Map, a variety of other mapping APIs have been introduced primarily to circumvent Google’s pricing structure.The cost for using Google Maps on websites has changed over the years. From 2005 to 2011, the use of Google Maps was free no matter how many maps were referenced by a website. From then to 2016, Google limited map downloads to 25,000 map loads a day for 90 consecutive days. In 2016, the 90 consecutive days was removed so the number of maps downloaded could not exceed 25,000 on any given day. If it did, the website developer needed to register their site and pay a fee for maps produced over this limit.In April 2018, Google announced the launch of a new name for the Google Maps API – Google Maps Platform – and a new pricing plan. A free tier continues to be offered through a US $200 monthly credit but now requires creating an account and entering a credit card number. In this new online platform, it is still possible to use the Google Maps API without incurring any cost by limiting the number of daily downloads so that the monthly quota of 28,000 map downloads is not exceeded.The problem is not the use of the Google Maps API but the Google map tiles. The look of maps from Google and the associated interface have become so popular that users avoid using other kinds of maps – even those from Apple. Users complain that the tiles from other vendors implement a different color scheme or highlight different features. They also complain that these maps appear more slowly. While other APIs can use Google Map tiles, including the popular Leaflet API, their use is still subject to the same pricing structure.With the help of the Internet, maps from Google have become the standard maps. All other renditions of the world are seen to be inferior and not worthy of examination. They are simply interesting oddities. While some can adapt to alternative representations, most choose not to. This Google Map phenomena is examined along with lessons from the historical progression of online mapping.
Interactive & Multiscale Thematic Maps: A Preliminary Study
Authors: Roth Robert E. , Kelly Meghan , Underwood Nick , Lally Nick , Vincent Kristen , Sack Carl
Published: July 2019

Abstract. Problem: Interactive or “slippy” web maps have revolutionized cartography. Slippy maps present a single, coherently-designed reference map that can be panned to numerous geographic locations and zoomed across multiple scales. Further, they apply scale-dependent style rules to detailed geographic datasets, with the resulting designs rendered as a large set of interlocking tiles. To account for constraints in data bandwidth, processing, and storage, only those tiles relevant to the user’s location and past interactions are served into the web browser or other application, resulting in a seamless, real-time user experience of “a map of everywhere”. These slippy tilesets often are used as basemaps for advanced cartographic web and mobile applications, overlaying thematic information and other linework. Arguably, such slippy map mashups are the most common map seen and used today (and perhaps of all time). Yet, most of the cartographic design canon was developed long before slippy maps were possible. Do any of our time-tested design traditions in thematic cartography apply in today’s interactive and multiscale mapping context? In this presentation, we discuss preliminary insights from an online map study about the design of interactive and multiscale thematic maps.
Fuzzy Expression of Hand-drawn Paths in We-Map Environment
Authors: Shen Ruru , Yan Haowen , Lu Xiaomin , Sun Qinke
Published: July 2019

Abstract. We-Map is a “grassroots” map for the general public and the hand-drawn paths function makes it a kind of “Personal Media” with strong interactivity. The hand-drawn paths are manually drawn by the “grassroots” public and intuitively show the paths to the destination. The fuzzy expression of the hand-drawn paths has low requirements on direction, distance and topological relationship. Compared with traditional navigation with high precision requirements, its expression is more easily accepted by the “grassroots”.In real life, the public's perception of geographic navigation is biased towards fuzziness and templating. Taking the location of the China National Stadium (Bird's Nest) as an example, the “grassroots” public is usually expressed near the Beijing Olympic Park or by subway line 15 or subway line 8 at the exit of the Olympic Park Station D. This expression is different from the traditional Accurate and standardized navigation. Therefore, this paper combines a new generation of We-Map concept with map as the information carrier, expresses the recommended path from the departure point to the destination in the form of hand-drawn maps fuzzification and template, and explores and designs a model suitable for mobile devices.The basic ideas are as follows: (1) Determining the place of departure and destination. (2) The expression design of the hand-drawn path is fuzzy: firstly, the projection and calculation of the fitting path, and then extracting the multi-level feature points of the facilities around the road by using the feature points extraction principle. Finally, corner calculations and template nesting at the corners. (3) The definition of fuzzification is as follows: “starting from the starting point, follow the XX road, go straight to the XX place near XX, turn right/left to XX road, and to the XX place near XX, reach the end point”. The template can be expressed as: “starting point, along the line, turn, end point”. (4) Matching multi-user and multi-map versions to hand-drawn maps with fuzzified expression. Take a case from this model: departure at the entrance of Feitian Hotel, Lanzhou City, Gansu Province, and destination at Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences.
Indoor path visualization method based on the spatial characteristics of indoor environment
Authors: Shi Jiafeng , Shen Jie , Stachoň Zdeněk , Chen Yawei
Published: July 2019

Abstract. With the increasing number of large buildings and more frequent indoor activities, indoor location-based service has expanded. Due to the complicated internal passages of large public buildings and the three-dimensional interlacing, it is difficult for users to quickly reach the destination, the demand of indoor paths visualization increases. Isikdag (2013), Zhang Shaoping (2017), Huang Kejia (2018) provided navigation services for users based on path planning algorithm. In terms of indoor path visualization, Nossum (2011) proposed a “Tubes” map design method, which superimposed the channel information of different floors on the same plane by simplifying the indoor corridor and the room. Lorenz et al (2013) focused on map perspective (2D/3D) and landmarks, developed and investigated cartographic methods for effective route guidance in indoor environments. Holscher et al (2007) emphasized using the landmark objects at the important decision points of the route in indoor map design. The existing studies mainly focused on two-dimensional plane to visualize the indoor path, lacking the analysis of three-dimensional connectivity in indoor space, which makes the intuitiveness and interactivity of path visualization greatly compromised. Therefore, it is difficult to satisfy the wayfinding requirements of the indoor multi-layer continuous space. In order to solve this problem, this paper aims to study the characteristics of the indoor environment and propose a path visualization method. The following questions are addressed in this study: 1) What are the key characteristics of the indoor environment compared to the outdoor space? 2) How to visualize the indoor paths to satisfy the users’ wayfinding needs?
Emotion maps
Authors: Cartwright William
Published: July 2019

Abstract. My perspective of Emotion Maps is not maps of emotions or the emotions evoked by spaces mapped or by mapping emotions evoked through the process of moving through a space. But – it is what we experience as ‘emotional uplifting’, when we view a cartographic artefact, whereby we elevate that artefact from a tool to communicate about geography to a piece of art. This is based on the premise of ‘Emotional Architecture’ proposed by by Mathias Goéritz in 1953 to describe an architecture elevated to art for the purpose of inspiring emotion (Loiseau, 2017). This led me to thinking about whether there are any maps that also inspire emotion. As rightly noted by a reviewer of this contribution (and thank you to reviewers for considering this paper and your welcomed reviews), what I am probably addressing is ‘aesthetic pleasure’. However, in order to ‘fit’ with Goéritz’s Emotional Architecture concept, I have stayed with my original title. As my research background is not in the area of Art and Cartography, I acknowledge that here I tread on dangerous ground. The reason for undertaking this research was to ascertain whether certain cartographic products may, when viewed, inspire viewers and uplift their emotions. This proposition needed to be tested by assessing a selection of cartographic artefacts against one Art theory. The theory papers from the era that was applied is Warehouse Theory.

Published: July 2019

Abstract. On July 23, NOAA Coast Survey hosted a three-day Chart Adequacy Workshop that included participants from 13 countries. This is the fourth Chart Adequacy Workshop held at National Oceanic and Atmospheric Administration’s (NOAA) Silver Spring, Maryland campus. This was the fourth workshop hosted by NOAA and Nippon Foundation / General Bathymetric Chart of the Oceans (GEBCO) Training Program at the Center for Coastal and Ocean Mapping, UNH. Unlike previous years (2017, 2016, 2015), the focus of this week was on networking and support for the upcoming International Cartographic Association (ICA) Working Group on Marine Cartography meeting held on July 26 and in preparation for next year’s International Cartographic Conference (ICC). The main goal of the workshop is to provide training for professional cartographers and hydrographers on techniques for assessing nautical chart adequacy using publicly-available information, such as satellite images and maritime automatic identification system (AIS) data. . The participants received an overview on Coast Survey datasets, processes, and requirements for nautical charts. They also learned about pre-processing hydrographic data, such as loading charts, uploading imagery, and applying electronic navigation charts (ENCs) and AIS point data. Through a series of lab units, the attendees practiced performing the concepts they learned.The 2018 participants were from Australia, Greece, Ireland, Japan, Latvia, Madagascar, Mexico, Nigeria, Peru, Poland, St. Vincent and the Grenadines, Taiwan, and Trinidad and Tobago. The international nature of the event allows the participants to meet and learn from cartographers from a variety of backgrounds and expertises. Thee individuals include Nippon Foundation / GEBCO training program students and those nominated by their home hydrographic offices and their travel was sponsored through funds secured by the workshop organizers. The workshop was developed in part too address the need to improve the collection, quality, and availability of hydrographic data world-wide, and increase the standardization of chart adequacy evaluations across the globe. Coast Survey is currently working with the International Hydrographic Organization (IHO) to recommend participants for next year’s workshop towards the end of July, 2019.
Analysing the Symbology of Soviet Military City Plans
Authors: Davis Martin , Kent Alexander J.
Published: July 2019

Abstract. The collapse of the Soviet Union has seen the emergence of its unprecedentedly comprehensive global military mapping programme and the commercial availability of a vast number of detailed topographic maps and city plans at several scales. This paper presents an analysis of the symbology devised by the Soviet Union for its series of secret military plans, which covered over 2,000 towns and cities outside the USSR. Analyses of symbol specification documents and the implementation of their symbology in a 1% sample (19) of these plans allow its relationship with the urban characteristics of the towns and cities they symbolise to be explored.In particular, this investigation assesses the extent to which the Soviet symbology is adopted across a variety of socio-cultural and physical environments at 1:10,000 and 1:25,000 scales. This reveals new details of the most comprehensive, globally-standardised topographic symbology ever produced, incorporating 630 graphical symbols in total, with 47.0% and 52.1% of these used in the sample of maps at both scales respectively. Elements of the physical environment account for the largest components of the symbology, with ‘Hydrography and Coasts’ the largest feature class at 1:10,000 (84 symbols) and ‘Vegetation and Soils’ at 1:25,000 (66 symbols). A comparative analysis with the OpenStreetMap symbology indicates scope for Soviet mapping to be used as a valuable supplementary topographic resource in a variety of existing and future global mapping initiatives, including humanitarian crisis mapping. This leads to a conclusion that the relevance and value of Soviet military maps endures in modern applications, both as a source of data and as a means of overcoming contemporary cartographic challenges relating to symbology, design and the handling of large datasets.
Visualizing and Linking Cartographic Resources across Discovery Environments
Authors: Durante Kimberly , Prince Emily
Published: July 2019

Abstract. This presentation will highlight Stanford University Libraries’ development of institutional best practices for identifying relationships among cartographic resources stored within the university’s digital preservation repository and made available to end users from contextualized discovery catalogs: SearchWorks and EarthWorks. The use of map interfaces as a tool for searching and retrieving of geographic information has greatly influenced the design of structural metadata and the related management of elegant workflows for supporting consistent procedures, both amongst the cartographic metadata librarians, as well as across greater Stanford Library policies. As collections of maps, atlases, and geospatial imagery are increasingly being digitized and georeferenced for use in a number of research contexts and purposes, new digital data are produced and made available through spatial data infrastructures, geoportals, and programmatic APIs. Our goal is to preserve the lineage that exists between primary source materials - such as centuries-old maps - and their derivative or versioned datasets, and to make this track both transparent and easily actionable for end users who are evaluating materials found through search engines or contextualized discovery platforms. The goal is to provide users with easily navigable links between the source materials and all subsequent versions. Our work relies on the use of structured metadata to define relationship types that commonly exist between cartographic materials old and new, and includes the use of persistent links that direct users to both source materials, as well as to georectified imagery, or shapefile index maps that are based upon those source materials. Using examples of Japanese maps of Tokyo, from several of Stanford’s rare and historic cartographic collections (housed at the East Asia Library, David Rumsey Map Center, and Branner Earth Sciences Library), we will present a standardized list of relationships which are prevalent among cartographic data collections and we will demonstrate how we have designed and leveraged metadata in these cases in order to facilitate the user’s intuitive discovery, reuse, and citation of related map content.
Liber chronicarum, Carta marina and other mappae mundi
Authors: Fijołek-Soska Beata
Published: July 2019

Abstract. Published in 1493, Liber chronicarum by Hartmann Schedel contains one of the most unique maps of that period. It shows a pantheon of monsters who were believed to inhabit the lands at the edge of the world known to people back then. Olaus Magnus, author of Carta marina, which was printed in 1539, adorned the water areas on his map with a variety of sea creatures, from those posing as islands to mythical creatures, such as the unicorn or Charybdis. Both these maps originate in the medieval mappae mundi tradition – illustrated compendia of the regions they present. A curious reader would perceive that they are heavily influenced by the works of antique and medieval cartographers: Pomponius Mela, Pilny the Elder, Bede the Venerable and Vincent of Beauvais. The phantasmagorical quality of the creatures on these maps is an interesting starting point from which to reflect on the following question: why, on a cognitive level, do these old maps – just as in fairy tales about the unknown, the mysterious and the dangerous – give their warnings in the metaphorical form of monsters? The similarity between mappae mundi and fairy tales is no accident. According to Marina Warner’s Once upon a Time, nannies told children fairy tales to familiarise them with everyday problems and dilemmas, to shed light on the complexities of interpersonal relations, and to explain the workings of the world.
Borderknots – cartographying experiences of crossing borders
Authors: Gattinger Katrin
Published: July 2019

Abstract. Borderknots is a drawing-performances project that I began in 2013 and through which I “graphically connect” borders of different nature with the help of a rudimentary drawing machine I developed: Inside a wooden box, a tracer produced a line on a paper sheet according to the movements, the accelerations, the vibrations, the shocks which it undergoes. Worn straight from the body or fixed to the door-luggage of a bicycle (Fig. 1), the instrument works as a seismograph recording graphically my journey, including the consequences of meeting the route, a harshness on the ground, a muscular fatigue or a fall. The routes so traveled and fixed on paper are always bound to the crossing of an obstacle or a frontier, real and concrete, political or symbolic, a limiting border physical or invisible, in charge, harmless. At the same time every paper of the project being carved of simple forms linked to the performance to come (in the obstacle to be exceeded), the pen meets then an obstacle in the irregular surface of the sheet of paper itself, too. The way it reacts response to the constraints that impede the flow of movement and reorient impulses of the Borderknots-performances and the border-behaviour in general. The drawing is the capture of an effort, a cartography of a more or less difficult and risky crossing. In its cash demonstration – cross 101 times a barrier (Borderknots - Crossing urban barriers, 2013); cross 28 times the French-German border as fast as possible (Borderknots - Europe round trip, 2013 / Fig. 2); or the relation between the unlimitedness of the obstacle and the simplicity of the obtained drawing (Borderknots - Crossing the Alps 1 and 2, 2014) – this effort sometimes lends to laughter: a certain irony participates unmistakably in the project. The political dimension takes however a more dominant aspect, particularly with the performances consisting in a penetrating into the representations of various countries present in the same city (consulates of Strasbourg / embassies in Brussels, 2013 / Fig. 3). The application of the stamp of every country straight on the drawing being made, is not only a proof of my path, but also outcomes of the negotiations (often difficult) begun in every stage with the various hierarchical authorities of the administrations around the artistic project. The maps thus produced and authenticated by seals, are at first glance abstract, but definitively very official drawings: like generalized visas for freedom of movement. Instead of a borderline, the title “Borderknots” propose making knots. It is to be said a tie, a link, but also a scrawl difficult to undo and representative of the complexity of certain limits. The lines marked by these machines during performances are in this way maps of the experiences of territories: straying, hesitating, starting over, jumping straight, crossing, turning backwards.
Quartz crystal microbalance coated with PEDOT–PSS/PVA nanofiber for a high-performance humidity sensor

Published: July 2019

Abstract. Quartz crystal microbalance (QCM) coated with
poly(3,4-ethylenedioxythiophene) and polystyrene sulfonate mixed with polyvinyl
alcohol (PEDOT–PSS/PVA) nanofiber has been fabricated as a humidity sensor
using the electrospinning method. Three types of PEDOT–PSS/PVA nanofiber
sensors are fabricated with different needle-to-collector electrospinning
distances. The scanning electron microscope images confirm the presence of
beads in the nanofiber structure. The results show that the sensor mass
deposition increased with the decrease in needle-to-collector distance. The
best sensor performance is exhibited by the sample with medium
needle-to-collector distance (QCM NF 2). The QCM NF 2 nanofiber sensor shows
excellent sensitivity of up to 33.56 Hz per percentage point of relative humidity, with rapid
response (5.6 s) and recovery (3.5 s) times, good linearity, excellent
repeatability, low hysteresis, and long-term stability and response. The
QCM PEDOT–PSS/PVA nanofiber sensor provides a simple method to fabricate
high-performance humidity sensors.
What's streamflow got to do with it? A probabilistic simulation of the competing oceanographic and fluvial processes driving extreme along-river water levels
Authors: Serafin Katherine A. , Ruggiero Peter , Parker Kai , Hill David F.
Published: July 2019

Abstract. Extreme water levels generating flooding in estuarine and coastal environments are often driven by compound events, where many individual processes such as waves, storm surge, streamflow, and tides coincide. Despite this, extreme water levels are typically modeled in isolated open-coast or estuarine environments, potentially mischaracterizing the true risk of flooding facing coastal communities. This paper explores the variability of extreme water levels near the tribal community of La Push, within the Quileute Indian Reservation on the Washington state coast, where a river signal is apparent in tide gauge measurements during high-discharge events. To estimate the influence of multiple forcings on high water levels a hybrid modeling framework is developed, where probabilistic simulations of joint still water level and river discharge occurrences are merged with a hydraulic model that simulates along-river water levels. This methodology produces along-river water levels from thousands of combinations of events not necessarily captured in the observational records. We show that the 100-year still water level event and the 100-year discharge event do not always produce the 100-year along-river water level. Furthermore, along specific sections of river, both still water level and discharge are necessary for producing the 100-year along-river water level. Understanding the relative forcing driving extreme water levels along an ocean-to-river gradient will help communities within inlets better understand their risk to the compounding impacts of various environmental forcing, which is important for increasing their resilience to future flooding events.
Antecedents of Job Crafting Behavior within Organizations: The Role of Personal Resources, Job Resources and Perceived Opportunities to Craft in Employees Proactive Behavior
Authors: Van Wingerden Jessica , Poell Rob F
Published: July 2019

This study examines the impact of personal resources and job resources on employees’ perceived opportunities to craft and job crafting behavior. Based on research following the Job Demands and Resources (JD-R) theory, we hypothesize that personal resources (i.e., resilience and self-efficacy) and job resources (i.e., developmental opportunities and feedback) have a positive relationship with employees’ perceived opportunities to craft and actual job crafting behavior in multiple and interrelated ways. We collected data among employees working in various organizations and occupations in The Netherlands (N=810), and tested the hypothesized multiple mediation model using structural equation modelling (SEM) analyses. The outcomes of the study increase our knowledge of the factors affecting  job crafting behavior within organizations – including employee perceptions (perceived opportunities to craft), employee characteristics (personal resources), and work characteristics (job resources). Combining these antecedents, this study may help to better understand and to stimulate job crafting behavior at work.

Physalis peruviana L. is a plant that produces small sweet berries of great nutritional and medicinal importance. This plant is propagated mainly through seeds, which requires information on germination response to temperature and light changes. Thus, the present study aimed to evaluate the use of different temperatures and light wavelengths on the physiological potential of P. peruviana seed batches. The experiment was conducted with seeds from plants cultivated in 2015/15 and 2016/16. The treatments applied were the following: two germination temperatures (constant temperature of 25 °C and alternated between 20/30 °C), two seed batches (2015/15 and 2016/16), and four forms of light exposure during germination (blue, red, white, and dark). The data were analyzed by principal component analysis using the correlation matrix obtained through the standardized mean equal to zero and variance 1 of the parameters evaluated for each treatment. The eigenvalues and eigenvectors of the matrix were obtained using the SAS University Edition® statistical software. The analyzed variables were: Germination test performed on the 7th and 28th day considering root protrusion, normal seedlings, shoot length, root length, and total dry matter mass. The data showed that the seed germination test of Physalis peruviana L. should be performed under a constant temperature of 25 °C, in the presence of light (white, blue, or red). When the option is the application of the test in the dark, it is necessary to use a thermoperiod of 20–30 °C to provide the expression of maximum physiological potential.

In the final steps of a breeding program, it is necessary to evaluate several traits, which makes it difficult to select the superior genotypes. This study aimed to compare nonlinear indexes in the selection of superior soybean inbred lines obtained by recurrent selection. The experiment was carried out in Londrina, Paraná State, Brazil. During the 2010/11 and 2011/12 seasons, 67 soybean inbred lines and two commercial controls (BMX Potência RR and NK 7059 RR) were evaluated. The experimental design was a randomized complete block with three replicates. The evaluated traits were: days to maturity, agronomic value, lodging, first pod insertion height, and grain yield. A combined analysis of variance for seasons was performed and the sum of ranks index, ideotype distance index, and cultivars selection index were applied. All traits were significant for the genotypic source of variation and showed complex genotype × environment interactions. The selection indexes were consistent with each other. The ideotype and cultivar selection index showed higher concordance on indication of 15 superior inbred lines with a coefficient of coincidence of 80%. The inbred lines SR-03, SR-12, SR-22, SR-41, SR-49, SR-55, SR-61, and SR-62 were indicated for all indexes and are therefore considered superior to other inbred lines.

Cassava is one of the main foods in Brazil, playing a key role in the diet of several communities. In the Central-Southern region of Brazil, several pests are associated with cassava, among which the cassava mealybug stands out due to its high potential for damage. The aim of the present study was to evaluate the population dynamics and the effect of pruning and different cassava management on the developmental stages of mealybug, Phenacoccus. manihoti. The experiment was conducted in Santa Monica, PR, with ‘Cauiá’ cultivar, involving a randomized complete block design with four replications and six treatments: 1) No pruning: intact plants, 2) Pruning soil: pruned close to the soil without plant material, 3) Pruning at 15 cm: conventional pruning at 15 cm of the soil with vegetative material, 4) Pruning + branches: conventional pruning, with the middle portion of the plant in the plot and removal of the apical region of the plant, 5) Pruning + apical: conventional pruning, with the removal of the middle portion of the plant and retaining the apical parts of the plant, and 6) Pruning - branches - apical: conventional pruning, with the removal of the middle and apical portions of the plant. After 7-days of pruning, the number of eggs, nymphs, and adults were counted, and the population variation was monitored at weekly interval for a month. For the insect count, four sites were randomly chosen in a zigzag manner within each plot and four plants were evaluated, totaling 16 plants per plot. Based on the counts, the percentage of plants with eggs, nymphs, and adults was calculated. The data of the variables were transformed by ?(x+5), subjected to analysis of variance and Scott Knot test (5%). The percentage of plants with egg mass and adults of P. manihoti was highest in plots that had no pruning. The pruning close to the soil combined with the removal of vegetative material resulted in plants with fewest eggs of P. manihoti. Removal of the apical region portion of the cassava plant reduced the number of P. manihoti nymphs and adults.

In the Northeast of Brazil, goat breeding plays an important socioeconomic and strategic role in coexistence within the semi-arid region. The rural nature of the species and adaptations that are appropriate for the climate are some of the characteristics that favor the Northeast as the largest national producer of goats (93% of the national herd). In spite of this, sanitary deficiencies facilitate the appearance and diffusion of pathogenic agents that compromise the productivity, e.g., Corynebacterium pseudotuberculosis, which are widespread in the national herd and cause damages in the industry. The objective of this study was to characterize caseous lymphadenitis (CL) in lamb cuttings at semi-arid abattoirs. The research was carried out between March and August 2017 at the Municipal Abattoir of Patos, State of Paraíba, Brazil, where the caprines from this region are slaughtered. We studied 304 animals with no defined racial pattern, of both the sexes, characterized according to their age group as evidenced by their teeth, submitted to ante- and post-mortem examinations with microbiological confirmation. Cheek material was processed for diagnostic confirmation, using the techniques of isolation and microbiological identification (gold standard). The bacteriological examination confirmed the presence of the agent in 21.38% of the animals, in which 13.16% were females and 8.22% were males. Of those affected, 11.51% had the clinical form of the disease, while 9.87% had the subclinical form and 1.31% had both the clinical form as well as the internal impairment. The precrural (25.71%), mammary (11.43%), and prescapular (11.43%) lymph nodes were the most affected. Internally, the most affected were the liver (63.33%), lung (13.33%), and medium mediastinal lymph nodes (10%). The presence of skin lesion/scars (Odds ratio = 2.394, 95% CI = 1.371 - 4.182, p = 0.003) and sex (females) (Odds ratio = 1.845, 95% CI = 1.053 - 3.232, p = 0.044) were found to be risk factors. CL is present in goats from the intermediate geographical region of Patos, reinforcing the need for control measures, with attention to the inspection of animals in the slaughter line.

During a physical examination of cattle, it is often difficult to evaluate inflammatory processes, particularly in cases where the inflammation occurs in deeper regions. The glutaraldehyde test (GT), carried out using a sample of whole blood, allows the visual and semiquantitative identification of an inflammatory process in cattle. Considering that there are few biochemical tests that can be used in the field, the objective of this study was to verify the efficacy of the GT in detecting and predicting mild and severe inflammatory processes in bovine species, classified according to a physical examination, and in the presence of different diseases or lesions. The GT was used in conjunction with a physical examination in 176 cows over 12 months of age, with additional laboratory evaluations of packed cell volume, total protein, albumin, globulin, and fibrinogen. Using a cutoff point at 3 minutes of coagulation, the GT showed a sensitivity of 35.1%, specificity of 94.1%, positive predictive value of 74.1%, and negative predictive value of 75.2%. The GT correctly detected the most severe inflammatory processes under the field conditions of this study. The GT is a diagnostic aid that can be used as a fast and simple screening test during the physical examination of cattle.

We evaluated the growth dynamics and forage production of Massai grass subjected to different cutting frequencies during the rainy season, with the aim to determine the most suitable cutting frequency to increase grass productivity. A randomized block design with four treatments (four cutting frequencies, 24, 32, 48, and 96 days) was used. The morphological characteristics were evaluated weekly in seven random tillers. Leaf appearance rate, phyllochron value, foliar elongation rate, leaf senescence rate, and stem elongation rate were influenced (p < 0.05) by the cutting frequency, while no effect was found for leaf life span. The number of live leaves per tiller, mean length of leaf blades, population density of tillers (DPP), and sheath length were influenced by the cutting frequency, along with plant height, dry mass of harvested leaf blade, dry mass of harvested stem, dry mass of harvested dead material, and leaf/stem ratio, while there was no effect on dry mass of forage harvested. The rates of leaf blade accumulation, stem accumulation, forage loss, and forage production were not affected by cutting frequency. A cutting frequency of 24 days resulted in the highest productivity values of Massai grass during the rainy season.

The objective of our study was to compare the intake and digestibility of dry matter and nutrients, and the nitrogen balance, of lambs fed extruded ration with different roughage (R) to concentrate (C) ratios. The experiment was carried out at the Federal University of Uberlândia (UFU), Experimental Farm Capim Branco, from 7 December 2016 to 6 January 2017. Ten lambs (Santa Inês × Dorper) aged between four and five months, and with a mean weight of 25.9 ± 2.8 kg, were used. The animals were placed in metabolic cages equipped with a feeder, drinking fountain, and salt shaker, and which had a wooden slatted floor. The treatments consisted of extruded ration with 30R:70C or 70R:30C. Treatments were distributed in a randomised, complete block design, with each treatment being performed twice and with ten replications. The experiment was carried out in two blocked stages. Differences in the means of treatments were evaluated by Tukey’s test at a significance level of 5%. Intake and digestibility of dry matter and nutrients, water intake by animals, and nitrogen balance were also analysed. The 30R:70C treatment resulted in a lower intake of dry matter, crude protein, neutral detergent fibre, acid detergent fibre and hemicellulose, and caused higher dry matter and neutral detergent fibre digestibility. The 30R:70C treatment also resulted in a lower intake and faecal excretion of nitrogen, consequently establishing a higher ratio between retained and ingested nitrogen. In conclusion, the ration with 30R:70C results in lower intake, and better utilisation of nutrients by the animal.
