Three-dimensional forward modelling and inversion of magnetotelluric data using unstructured meshes for understanding realistic geological systems: method development, algorithms and model construction for the Lalor deposit, Manitoba
Authors: Ansari S M , Craven J A , Schetselaar E
Published: March 2019

The work presented here covers three major branches of geophysical prospecting including the development of model construction routines for realistic subsurface structures, forward modelling and magnetotelluric inversion strategies. Using a combination of tools,
a routine is developed that produces a sealed model using tessellated geological surfaces representing lithostratigraphic contacts between rock units of the Lalor VMS deposit. This model is suitable for generating volumetric tetrahedral meshes required for mesh-based modelling and inversion of
geophysical data. A finite-element based forward modelling technique is developed that discretizes the magnetotelluric problem on un-structured tetrahedral meshes. These meshes are suitable for producing realistic complex-shaped features. Magnetotelluric responses for the Lalor model are
successfully calculated. A model space minimum-structure inversion is developed that is based on the iterative Gauss-Newton approach using sensitivity matrix-vector products calculated implicitly by finite-element based forward and pseudo-forward solutions.
Petrogenesis and associated mineralization of Acadian related granitoids in New Brunswick
Authors: Azadbakht Z , Rogers N , Lentz D R , McFarlane C R M
Published: March 2019

The Acadian-related granitoids of New Brunswick are herein divided into geochemically defined groups to ascertain whether magmatic process related trends differentiate barren from mineralized granitoids. The Juniper Barren and Lost Lake granites have some similar
characteristics (i.e. lowest SiO2, highest transition element contents, high-K calc-alkaline, metaluminous), but do not constitute a defined geochemical group. They have the characteristics of unfractionated (oxidized) I-type granites, and neither are associated with significant mineralization.
Group NB-1 granites are metaluminous to peraluminous, high-K calc-alkaline, light rare-earth element (LREE) enriched with small negative Eu anomalies, and high Nb/Ta and Zr/Hf ratios. Group NB-1 intrusions are interpreted to be unfractionated reduced I-type granite formed via partial melting in an
arc system and subsequently contaminated by reducing crustal rocks. The reduced component is critical for the formation of tungsten mineralization.
Group NB-2 granites are high-K calc-alkaline, metaluminous to peraluminous I-type granite characterized by K2O contents greater than Na2O, and are LREE enriched with pronounced negative Eu anomalies. Group NB-2 granites are unfractionated to weakly fractionated I-type granite generated from
different degrees of partial melting of mixed mantle - older crustal protolith with an igneous quartzo-feldspathic composition.
Group NB-3 granites include the most evolved intrusions examined during this study. They are characterized by the highest SiO2 content, Gottini index and K/Rb ratio, and have the lowest Zr/Hf, Nb/Ta, La/Sm and Eu/Eu* ratios. They are considered highly evolved I-type granite formed via crustal
thinning related to crustal delamination following the juxtaposition of crustal terranes during the Acadian Orogeny.
The relationship between the Ganderian Aspy and Bras d'Or terranes explored using Devonian plutonic rocks, Cape Breton, Nova Scotia
Authors: Grant C , Archibald D B , Kellett D A , Cottle J M
Published: March 2019

On Cape Breton Island, Nova Scotia, the Eastern Highlands Shear Zone bisects the Ganderia composite terrane, separating the Aspy and Bras D'Or terranes. The shear zone displays east-over-west, sinistral kinematics, and is intruded and stitched by plutonic rocks
of the Devonian Black Brook Granite Suite. This study is utilizing whole rock geo-chemistry, U-Pb zircon geochronology and Hf isotopic analysis to constrain the petrogenesis of the Black Brook Granite Suite and other spatially associated granitoid plutons in northern Cape Breton. The
granitoid-dominated plutonic suite is peraluminous, muscovite- and biotite-bearing, and interpreted to have formed from crustal anatexis. Published U-Pb monazite ages have constrained emplacement of the granite suite to ca. 375 Ma. Our new zircon geochronological data yielded weighted-mean U-Pb ages
between ca. 396 and 399 Ma, but individual zircon grains recorded younger ages in all samples. Our interpretation is that many of the analyzed zircon grains are inherited from host rocks and/or protolith, or that the pressure-temperature conditions of the magma were only hot enough to grow long,
slender zircon crystals not analyzed in this study. Thus, we interpret the timing of granitoid emplacement to be ca. 375 Ma. These results situate post-collisional plutonic rocks in northern Cape Breton Island in the temporal history of the Appalachian Orogen and can be used to constrain timing of
deformation on the Eastern Highlands Shear Zone.
Reactivation of the Eastern Highlands Shear Zone, Cape Breton Island, Appalachian Orogen
Authors: Piette-Lauzière N , Graziani R , Larson K P , Kellett D A
Published: March 2019

The Eastern Highlands shear zone (EHSZ), in the Cape Breton Island portion of Appalachian Orogen, records two ductile deformation events (D1 and D2) from Early Silurian to Late Devonian. The Devonian is a key period for the economic endowment of the orogen during
which intrusion-related mineralization may be associated with active and/or reactivated regional shear zones. The EHSZ is, therefore, a key structure to characterize shear zone reactivation and assess how this may have localized ore-bearing intrusive rocks. To accomplish this, we have first focused
on linking local deformation events to the regional kinematic framework. New U-Pb geochronology of zircon from de-formed specimens provide timing constraints on the two deformation events of the EHSZ. A rhyolite specimen with D1 fabrics and a granite dyke specimen affected by D2 deformation, both
within the EHSZ, yielded weighted mean 206Pb/238U crystallization ages of 424 ± 4 Ma and 372 ± 4 Ma, respectively (2-sigma error). In addition, two foliated quartz-diorite specimens and a post-tectonic pegmatite specimen from the Chéticamp gneiss, west of the EHSZ, yielded weighted
mean crystallization ages of 428 ± 9 Ma, 390 ± 8 Ma, and 391 ± 8 Ma, respectively. These new data constrain the EHSZ D1 to between ca. 424 and 390 Ma, likely during the Acadian Orogeny. The EHSZ was then reactivated (D2) after 372 Ma, which we attribute to the Neoacadian Orogeny.
Considering the orientations and kinematics of the Neoacadian suture and the EHSZ, we interpret that the EHSZ was reactivated in a transpression-dominated environment.

Published: March 2019

The composition of epidote and zircon in till and bedrock around copper porphyry mineralization in south-central British Columbia are investigated as an indicator towards deposits covered by glacial sediments. At the Gibraltar porphyry deposit, new dating reveals
that the Mine phase of the Granite Mountain batholith was emplaced during three intrusive pulses at ca. 205, 213 and 219 Ma. Zircon Ce4+/Ce3+ ratios, a potential fertility proxy, progressively decrease from an average of 681 in the earliest mineralized intrusive Mine phase (219 Ma) to 193 in the
younger intrusive phase (202-207 Ma). Zircon with Ce4+/Ce3+ values greater than 400, corresponding to a Ce/Nd ratio of 20, are most likely derived from the mineralized Mine phase. Two zircon grains with Ce/Nd ratios greater than 20 were identified in a till sample less than 1 km down-ice from
mineralization. Epidote grains in till from three porphyry localities (Mount Polley, Woodjam, and Gibraltar) and bedrock from Woodjam were analyzed to test the hypothesis that a simple correlation plot of Sb versus As could be used to differentiate epidote that formed in metamorphic versus
hydrothermal settings. Our preliminary results show a significant overlap between the As and Sb concentrations in epidote grains from till and epidote from the alteration zones at the Woodjam prospect. Future work will investigate whether epidote in till with low As (< 10 ppm) and Sb
(<1 ppm) levels could be derived from regionally metamorphosed rocks of the Nicola Group.
Geochemistry of U±Cu±Mo±V mineralization, Central Mineral Belt, Labrador: differentiating between mineralization styles using a principal component analysis approach
Authors: Acosta-Góngora P , Potter E G , Corriveau L , Lawley C J M , Sparkes G W
Published: March 2019

The Central Mineral Belt, Labrador, has experienced intermittent uranium exploration since the late 1950s. It hosts multiple U±Cu±Mo±V showings, prospects and deposits in Neoarchean to Mesoproterozoic meta-igneous and -sedimentary rocks. Uranium
mineralization occurs in metasomatic (albitite-hosted), magmatic- and magmatic hydrothermal-related (e.g. iron-oxide-carbonate-rich veins and breccias) and sedimentary-hosted (e.g. unconformity-related) systems.
In this contribution, we use the IOCG discrimination-alteration diagram and apply principal component analysis (PCA) to characterize hydrothermal alteration and ore element signatures at uranium occurrences included within the Central Mineral Belt Uranium Geochemistry database. Our results indicate
that sodium and Na-Ca-Fe-(Mg) metasomatism is more pervasive and regionally widespread than previously reported, and commonly hosts uranium mineralization; albitization itself may not be directly associated with uranium mineralization. Other second-order factors (e.g. proximity to structures) are
more likely to control uranium enrichment.
In the Jacques Lake and Michelin deposits and Two Time-Snegamook trend, uranium-mineralized samples yield positive PC2 scores and occur with Na- and Na-Ca-Fe-(Mg)-altered rocks. Our analysis also documents that PC3 represents a proxy for a second style of U-As-Mo mineralization that is better
defined in basalt-argillite-hosted systems (e.g. Moran Lake Upper C zone and Anna Lake deposits). The unusual U-As-Mo hydrothermal fingerprint may indicate: i) a synsedimentary origin of uranium (i.e. U-rich black shales) that was remobilized to upper stratigraphic levels; and/or ii) argillitic and
basaltic packages within the Moran Lake and Post Hill groups served as redox traps for oxidizing uranium-rich fluids that equilibrated with these rocks.
Characteristics of Ni-Cu-PGE sulphide mineralization within the 1.1 Ga Midcontinent Rift
Authors: Smith J , Bleeker W , Liikane D A , Hamilton M , Cundari R , Hollings P
Published: March 2019

Magmatic Ni-Cu-PGE deposits of the ca. 1.1 Ga Midcontinent Rift system occur in association with a diverse range of ultramafic-mafic intrusions, from small early rift conduits to large, layered, mafic intrusions such as the Duluth Complex. The nature and style of
mineralization is variable throughout these intrusions, some conduit deposits such as Eagle and Tamarack host massive nickel-copper sulphides, whilst others are relatively sulphur-poor but show extreme PGE enrichment (e.g. Current Lake; Marathon Deposit of the Coldwell Complex). The addition of
external sulphur (Proterozoic and/or Archean) is considered critical in the formation of many of the Ni-Cu-PGE deposits; however, the key factors controlling the style of mineralization and the base and/or precious metal content are yet to be determined. This research aims to address the processes
that are fundamental for metal enrichment and how these may vary both temporally and spatially during the rift's development. Furthermore, the Midcontinent Rift provides an excellent base to study the critical differences between mineralized and unmineralized intrusions, therefore providing the
opportunity to assess key controls on metal endowment.

Published: March 2019

This research activity investigates the metal endowments of magmatic ore deposits across the Superior Province in order to identify key metallogenic provinces and to develop an integrated genetic/exploration model. Almost all chromium deposits, including the
world-class deposits in the McFaulds Lake greenstone belt (a.k.a. 'Ring of Fire'), are located in the northern part of the Superior Province, predominantly within the Meso- to Neoarchean supracrustal successions of the Bird River-Uchi-Oxford-Stull-La Grande Rivière-Eastmain domains, whereas the
vast majority of the Ni-Cu-PGE deposits are located within the Wawa-Abitibi terrane. In this contribution, we present an initial compilation of chromium, Ni-Cu-PGE and Fe-Ti-V deposits hosted by ultramafic to mafic intrusions/flows in the Superior Province.
The feasibility of national parks in South Africa endorsing a community development agenda: The case of Mokala National Park and two neighbouring rural communities
Authors: Coetzee Hendri , Nell Werner
Published: March 2019

This article explores the feasibility of South African National Parks (SANParks) endorsing a community development agenda, using Mokala National Park (MNP) and two neighbouring rural communities as case study. A three-phase sequential exploratory, mixed-methods approach was followed: an initial exploratory qualitative phase aimed at identifying the development needs of the two communities; a quantitative phase aimed at verifying and quantifying the identified needs; and a final qualitative phase (with a minor quantitative component) to determine what parks can reasonably achieve in terms of community development based on their available resources, capacity and expertise. Qualitative data were collected via semi-structured interviews (Phase 1: n = 22; Phase 3: n = 6), which were thematically analysed. Quantitative data were collected via a structured questionnaire (Phase 2: n = 484; Phase 3: n = 6) and analysed using SPSS 23. Findings revealed that the communities’ most significant needs centred on employment opportunities; improved healthcare, service delivery and waste management; and education. Community members also expressed the need for improved community policing, safety and security; social services; agricultural support and training; general skills development and training; local leadership; recreational facilities; local economic development and conservation initiatives. Results from the third phase of the study suggest that parks such as MNP can realistically only address some of the identified community needs significantly; primarily job creation (via temporary employment), skills development, local economic development, support of local conservation (especially via environmental education) and, to a lesser extent, agricultural support and training and permanent job creation.Conservation implications: The findings could be of practical use to SANParks to steer its community development initiatives towards attaining a more optimal balance between actual community needs and what the organisation can realistically offer, thus rendering SANParks’ efforts more efficient and effective in supporting the establishment of equitable and sustainable rural communities.

Published: March 2019

This paper attempts to explain the role of capital inflows in creating economic booms and busts in a small open economy with sovereign currency. We develop a stock–flow consistent (SFC) model for a small open economy while relying on the experience of the Icelandic crisis. We demonstrate the destabilising effects of capital inflows on the economy by allowing for a sudden stop, and also discuss the role of capital controls as a policy response in the event of a crisis due to sudden stops. Finally, we discuss the policy implications of our results in order to tackle the destabilising effects associated with financial flows in a small economy.
Vehicle Modification Prescription: Australian Occupational Therapy Consensus-Based Guidelines
Authors: Di Stefano Marilyn , Stuckey Rwth , Kinsman Natasha , Lavender Katrina
Published: March 2019

Vehicle modifications are often essential to ensure that drivers with disabilities can drive independently and safely. Occupational therapy driver assessors and driver rehabilitation specialists routinely prescribe vehicle modifications on the basis of individualized evaluations and support by rehabilitation interventions. After a literature review and consultation with stakeholders, we identified a resource gap in information to support an evidence-based process for vehicle modification prescription. Using an action research approach, we established content validity for draft guideline items and developed consensus-based draft guidelines for vehicle modification prescription that are ready for trialing by occupational therapy driver assessors. We also propose a practice model for vehicle modification prescription that is applicable to international contexts.
Occupational Therapists’ Perceptions of Online Competence Assessment and Evidence-Based Resources
Authors: Myers Christine T.
Published: March 2019

OBJECTIVE. This study explored U.S. occupational therapists’ perceptions of online competence assessment and associated evidence-based resources.

METHOD. The study used a cross-sectional design with a survey. Respondents were occupational therapists certifying or recertifying with the National Board for Certification in Occupational Therapy in March 2016.

RESULTS. The response rate was 88.6%, with 58.5% indicating they had used the online competence assessment platform. A majority agreed that the platform’s tools helped them identify clinical knowledge (n = 211; 79.9%) and skill needs (n = 160; 60.8%). Of those who obtained copies of the evidence-based resources (n = 98; 45.6%), 72.5% (n = 71) read at least one. Chi-square analysis demonstrated negative relationships between years as an occupational therapist and clinical skills assessment and between highest degree and use of evidence-based practices.

CONCLUSION. Online competence assessment assisted participants in identifying competence needs and evidence-based resources for improving clinical knowledge and skills.
Cognitive, Emotional, and Physical Functioning as Predictors of Paid Employment in People With Stroke, Traumatic Brain Injury, and Spinal Cord Injury
Authors: Wong Alex W. K. , Chen Cynthia , Baum M. Carolyn , Heaton Robert K. , Goodman Berrit , Heinemann Allen W.
Published: March 2019

OBJECTIVE. Our objective was to examine demographic, cognitive, emotional, and physical factors that predict return to paid employment for people after neurological injury.

METHOD. Four hundred eighty adults with stroke (n = 149), traumatic brain injury (n = 155), and spinal cord injury (n = 176) completed an occupational outcome questionnaire and physical, emotional, and cognitive assessments at three rehabilitation facilities.

RESULTS. Odds of employment were predicted by being married or partnered, having more education, requiring fewer prompts for task sequencing, and having higher inhibitory control (but were not predicted by specific type of injury). Participants who returned to work within 3 mo were more likely to work with the same employer and to take a full-time position than those who returned later.

CONCLUSION. Executive functioning, in particular sequencing and inhibitory control, strongly predicts employment and highlights the importance of cognitive strategy training during occupational therapy with people who have sustained neurological injuries.
Blue, White of Grey CollarsHoe Diep is Het Water Wanneer Het Gaat Om Zinvol Werk?
Authors: Prins Peggy , Stuer David , Vos Ans de
Published: March 2019

Werk heeft belangrijke zingevende functies en heeft daardoor een potentieel positief effect op het leven van mensen: het biedt idealiter een inkomen, het zorgt voor sociaal contact, het geeft meer zin en regelmaat aan het leven en het draagt potentieel bij aan iemands eigenwaarde en
welzijnsgevoel. Of en waarom mensen hun werk als zinvol ervaren, is dan ook van oudsher een belangrijk vraagstuk in het arbeidspsychologisch en -sociologisch onderzoek. Wij zoomen in dit artikel in op de vraag welke verschillen bestaan in de gradatie en de determinanten van zinvol werk voor
drie beroepsgroepen: de blue, white en grey collars. Waar de termen 'blue en white collars' gemeenzaam bekend zijn, is dat veel minder het geval voor de term 'grey collars'. Het gaat stereotiep om de 'grijze pakken', om de kader- of de leidinggevende functies. Hoe diep of ondiep is het water
tussen deze drie groepen wanneer het gaat om percepties van (determinanten van) zinvol werk?How deep or shallow is the water between blue, withe and grey collars when it comes to perceptions of (determinants of) meaningful work? That’s the key focus of the article. In line with self-determination theory we examine the impact of (the fulfilling of the need of) autonomy and (the fulfilling of the need of) social support on experienced meaningfulness. Additionally, in line with Person-Environment Fit theory, we expect a mediation effect by needs-supply fit or misfit dependent on the type of professional ‘collar’ (blue, white or grey) of the employee. The results of the explanatory analysis of our survey (n=9307) shows that the expected relationships in our models are quite collar-independent, meaning that the drivers for meaningful work are almost the same for blue, white as well as for grey collars. This does not mean that the nature of the ‘collar’ of the workers has no impact at all. The descriptive results demonstrates less meaningful work perceptions, less needs-supply fit, less autonomy and social support for blue collar workers, compared with white and grey collars. Extra attention for those groups who are working in a more executive mode is therefore required.

Abstract. Atmospheric new particle formation (NPF) is a common phenomenon all over
the world. In this study we present the longest time series of NPF records in
the eastern Mediterranean region by analyzing 10 years of aerosol number size
distribution data obtained with a mobility particle sizer. The measurements
were performed at the Finokalia environmental research station on Crete,
Greece, during the period June 2008–June 2018. We found that NPF took place
on 27 % of the available days, undefined days were 23 % and non-event
days 50 %. NPF is more frequent in April and May probably due to the
terrestrial biogenic activity and is less frequent in August. Throughout the
period under study, nucleation was observed also during the night. Nucleation
mode particles had the highest concentration in winter and early spring,
mainly because of the minimum sinks, and their average contribution to the
total particle number concentration was 8 %. Nucleation mode particle
concentrations were low outside periods of active NPF and growth, so there
are hardly any other local sources of sub-25 nm particles. Additional
atmospheric ion size distribution data simultaneously collected for more than
2 years were also analyzed. Classification of NPF events based on ion
spectrometer measurements differed from the corresponding classification
based on a mobility spectrometer, possibly indicating a different
representation of local and regional NPF events between these two measurement
data sets. We used the MALTE-Box model
for simulating a case study of NPF in the eastern Mediterranean region.
Monoterpenes contributing to NPF can explain a large fraction of the observed
NPF events according to our model simulations. However the adjusted
parameterization resulting from our sensitivity tests was significantly
different from the initial one that had been determined for the boreal
environment.
Characterization of flow recirculation zones at the Perdigão site using multi-lidar measurements
Authors: Menke Robert , Vasiljević Nikola , Mann Jakob , Lundquist Julie K.
Published: March 2019

Abstract. Because flow recirculation can generate significant amounts of turbulence, it
can impact the success of wind energy projects. This study uses unique
Doppler lidar observations to quantify occurrences of flow recirculation on
lee sides of ridges. An extensive dataset of observations of flow over
complex terrain is available from the Perdigão 2017 field campaign over a
period of 3 months. The campaign site was selected because of the unique
terrain feature of two nearly parallel ridges with a valley-to-ridge-top
height difference of about 200 m and a ridge-to-ridge distance of 1.4 km. Six scanning Doppler lidars probed the flow field in several vertical planes
orthogonal to the ridges using range–height indicator scans. With this lidar
setup, we achieved vertical scans of the recirculation zone at three
positions along two parallel ridges. We construct a method to identify flow
recirculation zones in the scans, as well as define characteristics of these
zones. According to our data analysis, flow recirculation, with reverse flow
wind speeds greater than 0.5 m s−1, occurs over 50 % of the time
when the wind direction is perpendicular to the direction of the ridges.
Atmospheric conditions, such as atmospheric stability and wind speed, affect
the occurrence of flow recirculation. Flow recirculation occurs more
frequently during periods with wind speeds above 8 m s−1.
Recirculation within the valley affects the mean wind and turbulence fields
at turbine heights on the downwind ridge in magnitudes significant for wind
resource assessment.
Simulation study for ground-based Ku-band microwave observations of ozone and hydroxyl in the polar middle atmosphere
Authors: Newnham David A. , Clilverd Mark A. , Kosch Michael , Seppälä Annika , Verronen Pekka T.
Published: March 2019

Abstract. The Ku-band microwave frequencies (10.70–14.25 GHz)
overlap emissions from ozone (O3) at 11.072 GHz and hydroxyl radical
(OH) at 13.441 GHz. These important chemical species in the polar middle
atmosphere respond strongly to high-latitude geomagnetic activity
associated with space weather. Atmospheric model calculations predict that
energetic electron precipitation (EEP) driven by magnetospheric
substorms produces large changes in polar mesospheric O3 and OH.
The EEP typically peaks at geomagnetic latitudes of ∼65∘ and evolves rapidly with time longitudinally and over the
geomagnetic latitude range 60–80∘. Previous
atmospheric modelling studies have shown that during substorms OH
abundance can increase by more than an order of magnitude at 64–84 km and
mesospheric O3 losses can exceed 50 %. In this work, an atmospheric
simulation and retrieval study has been performed to determine the
requirements for passive microwave radiometers capable of measuring diurnal
variations in O3 and OH profiles from high-latitude Northern
Hemisphere and Antarctic locations to verify model predictions. We show
that, for a 11.072 GHz radiometer making 6 h spectral measurements with
10 kHz frequency resolution and root-mean-square baseline noise of
1 mK, O3 could be profiled over 8×10-4–0.22 hPa
(∼98–58 km) with 10–17 km height resolution and
∼1 ppmv uncertainty. For the equivalent 13.441 GHz
measurements with vertical sensor polarisation, OH could be profiled over
3×10-3–0.29 hPa (∼90–56 km) with 10–17 km
height resolution and ∼3 ppbv uncertainty. The proposed
observations would be highly applicable to studies of EEP, atmospheric
dynamics, planetary-scale circulation, chemical transport, and the
representation of these processes in polar and global climate models. Such
observations would provide a relatively low-cost alternative to
increasingly sparse satellite measurements of the polar middle atmosphere,
extending long-term data records and also providing “ground truth”
calibration data.
PLANNING HARVESTING OPERATIONS IN FOREST ENVIRONMENT: REMOTE SENSING FOR DECISION SUPPORT
Authors: Piragnolo M. , Grigolato S. , Pirotti F.
Published: March 2019

Abstract. The goal of this work is to assess a method for supporting decisions regarding identification of most suitable areas for two types of harvesting approaches in forestry: skyline vs. forwarder. The innovative aspect consists in simulating the choices done during the planning in forestry operations. To do so, remote sensing data from an aerial laser scanner were used to create a digital terrain model (DTM) of ground surface under vegetation cover. Features extracted from the DTM are used as input for several machine learning predictors. Features are slope, distance from nearest roadside, relative height from nearest roadside and roughness index. Training and validation is done using areas defined by experts in the study area. Results show a K value of almost 0.92 for the classifier with best results, random forest. Sensibility of each feature is assessed, showing that both distance and height difference from nearest road-side are more significant than overall DTM value.
INTEGRATING MULTI-TEMPORAL SAR IMAGES AND GPS DATA TO MONITOR THREE-DIMENSIONAL LAND SUBSIDENCE
Authors: Ito H. , Susaki J. , Anahara T.
Published: March 2019

Abstract. Synthetic aperture radar (SAR) is an effective means of monitoring land subsidence, and differential interferometric SAR (DInSAR) is commonly used to acquire the necessary data. In particular, persistent scatterer interferometry (PSI) can be used to measure land subsidence accurately over a wide area from multi-temporal SAR images. However, the estimated displacement is obtained only in the radar line-of-sight (LOS) direction, making it necessary to develop a method for measuring three-dimensional displacements by combining multidirectional observations. Therefore, we propose herein a method for estimating three-dimensional displacement velocities by combining the results from PSI and geodetic deformation measurements, namely, Global Positioning System and leveling data. We apply the least-squares method to Kansai International Airport in Japan by using 13 ALOS-2/PALSAR-2 ascending images from 2014 to 2018 and 17 ALOS-2/PALSAR-2 descending images from 2015 to 2018. In validation, the rootmean- square errors are 14, 16, and 14 mm/year for the east–west, north–south, and vertical components, respectively, showing that combining PSI results and geodetic deformation measurements is effective for monitoring land subsidence.
AGROFORESTRY TREE DENSITY ESTIMATION BASED ON HEMISPHERICAL PHOTOS & LANDSAT 8 OLI/TIRS IMAGE: A CASE STUDY AT CIDANAU WATERSHED, BANTEN-INDONESIA
Authors: Khairiah R. N. , Prasetyo L. B. , Setiawan Y.
Published: March 2019

Abstract. The Cidanau watershed is the only watershed in Indonesia that implements Payment for Environmental Services (PES) for farmers who can maintain tree/stand density of 500 trees/hectare on their land. Payments are made upon the verification on the field by the project supervisor. This method requires a lot of time and costly, so it is necessary to build more efficient indirect methods, including using satellite imagery or camera data. The aim of this study is to understand Landsat OLI 8 and hemispherical photo can estimate tree density in the farmer’s agroforestry stand. To obtain tree density, the number of trees with diameter more than 10 cm in 50 plots (50 m x 50 m) were counted. Some predictor variables were utilized, such as Leaf Area Index (LAI) based on hemispherical photos, Normalized Difference Vegetation Index (NDVI), Forest Cover Density (FCD), as well as NDVI and FCD which were enhanced with topographic correction. The imagery used was Landsat 8 OLI acquired on July 5, 2015, with Path/Row 123/64. The relationship between tree density and predictor variables was done using linear regression analysis. Prior to regression analysis, normality (Kolmogorov Smirnov/K-S), heteroscedasticity (Glejser test) and auto correlation (Durbin Watson) test were performed. The results of the analysis showed that tree density was estimated better with hemispherical photos-based LAI, with determination coefficient of 80.6%. Meanwhile, estimation using NDVI and FCD has lower determination coefficient. Even though, the use of topographic correction had been able to increase the determination coefficient of the regression relationship between tree density and FCD, from 4.64% to 35.18%.
ANALYSIS OF RELATIONSHIP BETWEEN VEGETATION DISTRIBUTION AND LAND PRICE USING MULTITEMPORAL DATA
Authors: Kumagai K. , Uematsu H.
Published: March 2019

Abstract. Japanese cities are facing a rapidly aging society with birthrates, lower than the average rates of developed world. Population decline generates many problems such as depopulation in rural areas. One of the measures implemented is to define core areas for maintaining sufficient population density given current and predicted population dynamics. On the other hand, there is a potential for the surroundings of the core areas to be run-down because vacancies generate many problems such as crime, susceptibility to fire, and other negative events. There have been, however, few measures concerning the spatial distribution of parks and open spaces around the core areas. We applied a hedonic approach with a Geographically Weighted Regression (GWR) to the analysis of the relationship between the assessed values of land and geographical information in order to estimate the importance of landscape factors: the spatial continuity of vegetation distributions, public parks, and the local averages of NDVI. It was shown that the number of points where the spatial continuity of vegetation distributions makes positive impacts on nearby land prices is gradually increasing during years 2000 and 2015, while the average of land price continues to fall.
STUDY ON EXTRACTION METHODOLOGY OF RICE GROWTH CHARACTERISTICS IN FIELD USING TERRESTRIAL LASER MEASUREMENT DATA
Authors: Sakata K. , Rikimaru A. , Yasunaga Y.
Published: March 2019

Abstract. Smart agriculture is recommended for labor-saving, refinement and high quality production of rice cultivation with safety and security. The Terrestrial laser measurement has the advantage of acquiring 3D point cloud information with high accuracy and high density, but there is a disadvantage that it becomes difficult to measure the base of rice plant when paddy rice grew. In this study, the 3D point cloud information obtained by terrestrial laser measurement was used to three-dimensionally measure the growth state in the field corresponding to the growing period in time series. The growth characteristics of the whole field as a community were extracted as a representative value of mean growth. Then we attempted extraction of individual differences in growth and growth unevenness, as the deviation from the mean value of the field in terms of the growth characteristics of each strain focused on the individual plants. it is difficult to observe the root of the rice during the growing period, it was used for analyzing the growth quantity as the growth difference height for each growing period by obtaining the difference of the elevation value of the rice at the early stage of growth and at each stage of growing. The spatial variation in the growth quantity of the whole field area and the local area was calculated, the range of the deviation for evaluating the mean variation and the growth abnormality was examined, and the setting of the threshold for evaluating the growth normal and abnormality was examined.
Towards Achievement of Gender Parity in Decision Making? Experience from the Participation of Male and Female MPs in the Parliament of Tanzania
Authors: Swai Idda Lyatonga , Masue Orest Sebastian
Published: March 2019

There have been gradual efforts to increase the number of female MPs in Tanzania through women empowerment creation of quotas (special seats) to enable them play an active role in this important decision making body. This article seeks to find out whether the increase in number of women MPs in the Tanzanian Parliament has influenced women’s degree of intervention in terms of: (1) asking basic questions; (2) asking supplementary questions; and (3) making contribution to parliamentary discussions. We obtained data from the official website of the Parliament of Tanzania, and analyzed them through descriptive statistics and multiple linear regression analysis. The results suggest that an increase in number of female MPs will increase their level of intervention; hence, we are inclined to the conclusion that numbers matter in determining female MPs’ influence in the Parliament.
Resolving polite conflicts in predicate agreement
Authors: Puškar-Gallien Zorica
Published: March 2019

When an agreement controller contains conflicting semantic and formal features, the predicates that agree with it can differ with respect to the type of features they reflect. With the second person pronoun used for politely addressing a single referent, finite verbs always agree in (formal) plural number, while participles in some languages may or must agree in (natural) singular number and gender. Building on the claims from the previous literature that the honorific pronoun formally encodes both the grammatical features (plural number and person) and the natural gender and singular number, the analysis proposed in this paper derives the variation in predicate agreement by combining the formal tools of feature geometries, separate probing and variation in the ordering of Agree operations. The main claim advanced by the paper is that predicates differ with respect to the φ-features they probe for, and the order in which this probing applies.
Parte 1: Alergia a la proteína de leche de vaca
Authors: López Robles Gabriela Alejándra , González Hernández Norma
Published: March 2019

La alergia a la proteína de leche de vaca (APLV) es la alergia alimentaria más frecuente en niños menores de 3 años, con una incidencia estimada entre 2-7.5%. Comprende reacciones mediadas IgE, no mediadas por IgE y mixtas. La APLV involucra tres sistemas: respiratorio, gastrointestinal y piel. Su diagnóstico es clínico y se conforma o excluye con la eliminación del alérgeno. Si el lactante es alimentado con leche materna la madre debe continuar con su administración, evitando alimentos que contengan proteína de leche de vaca y ella deberá recibir suplementos de calcio 1000 mg al día. Si recibe fórmula artificial, ésta debe ser eliminada e iniciar una fórmula extensamente hidrolizada. Dado que cada día la APLV está incrementando a edades mayores y observamos un aumento en la severidad, decidimos realizar la presente revisión y dar a conocer los factores de riesgo involucrados, para hacer un diagnóstico precoz y evitar así el compromiso sobre el estado nutricional, ya que por desconocer estos, la mayoría de los niños son sometidos a cambios frecuentes de fórmulas y eliminaciones dietéticas innecesarias.

Histología, es la rama de la anatomía que estudia los tejidos de animales y plantas. Aunque el término anatomía microscópica no es sinónimo, se utilizan indistintamente para referirse al estudio de la estructura microscópica de células, tejidos y órganos o sistemas. Para ello, ha sido indispensable el invento del microscopio que sucedió a partir del descubrimiento de vidrios, cristales y lentes que llevaron a inventar los microscopios simples luego los compuestos, evolucionando en el siglo pasado a la invención del microscopio electrónico con mayor poder de resolución de 250 o ångström (A). Para observar un tejido al microscopio es fundamental el uso de técnicas histológicas y colorantes. Han sido muchos los personajes de la historia de la medicina que han participado en describir histológicamente el cuerpo humano, es por ello que diferentes estructuras histológicas llevan epóni- mos o términos constituidos por los nombres propios de sus descubridores, ejemplo los “corpúsculo de Malphigie.” El Comité Internacional Federativo de Terminología Anatómica (FICAT) bajo los auspicios de la Federación Internacio- nal de Asociaciones de Anatomistas (IFAA), recibió el encargo de unificar la terminología morfológica internacional, publicando dicha terminología histológica el año 2008. La Asociación Panamericana de Anatomía (APA), fue fundada en 1966 en la ciudad de México y desde el año 2009 se realizan los Simposios Iberolatinoamericanos de terminología Anatómica, Embriológica e Histológica, (SILAT) con el objetivo de traducir al castellano la TERMINOLOGÍA MORFOLÓGICA INTERNACIONAL, para que las instituciones educativas de medicina y de otras áreas de la salud, de habla hispana y portuguesa, la empleen cotidianamente.
