Preliminary results of a study of the paleomagnetism of the Sudbury irruptive
Authors: Larochelle A
Published: March 2016

Measurements of paleomagnetic directions within the Sudbury irruptive were obtained from 265 cores drilled at 74 norite sites and 197 cores drilled at 55 micropegmatite sites. After elimination of data considered unreliable according to preset criteria of
acceptance, the remaining directions of magnetization (following a. f. cleaning in a peak field of 250 oe) were analyzed quantitatively and in terms of the known geological context. The low angular dispersion of the magnetization directions within large sectors of the irruptive and their remarkably
high stability during progressive demagnetization suggest that the magnetization measured is predominantly primary and of thermoremanent origin. This assumption was provisionally made in interpreting the results. A statistical analysis shows that the mean directions of magnetization of the norite
and of the micropegmatite are not significantly different in undisturbed sectors of the irruptive. It is inferred from this that the two rock units are probably contemporaneous. The low angular dispersion of the site mean directions of magnetization along profiles across the irruptive suggests
further that either the irruptive cooled rather rapidly or the paleomagnetic field was more stable at that time than at present. The data reported in this study were combined with data previously reported for the paleomagnetism of the irruptive, the blending of the two sets of data having been
justified on a statistical basis. The previously published geological interpretations of the irruptive's paleomagnetism still hold their respective merits although their original basis is more firmly established as a result of the present study. The validity of these interpretations can only be
tested through considerably more work which this study should help in planning.
Application of borehole stratigraphic techniques in areas of mountain glacial drift in Alberta
Authors: Rutter N W , Wyder J E
Published: March 2016

Presented here are the results of an integrated program of d rilling, side - wall sampling, and single - point electro logging that has been successfully carried out in areas of mountain glacial drift near Canmore and Calgary, in Alberta . The purpose of this
program was to obtain stratigraphic information that could not be acquired by conventional observational techniques. To date, reports from most test drilling programs using rotary hydraulic drills have consisted of descriptions of the chips carried to the surface by the drilling mud. Chip samples by
themselves do not provide sufficient evidence for the determination of detailed stratigraphy in areas of rapid lateral and vertical changes in lit h ology, such as Calgary and Canmore. In these areas, side-wall sampling techniques and electro-logs proved to be valuable stratigraphic tools, readily
eliminating ambiguities arising from the examination of chip samples alone. The results of this program were useful in confirming stratigraphic relationships based on previous surface mapping, in extending geological boundaries, in determining the thickness of lithologic units, and in the discovery
of new lithologic units.
Stanton map area [107d], Northwest Territories
Authors: Yorath C J , Balkwill H R
Published: March 2016

Exposed rocks in the Stanton map-area, which lies within the Anderson Plain and Arctic Coastal Plains, belong to the Devonian and Cretaceous Systems. Devonian rocks are represented by the hnperial Formation and occur along Kugaluk River. The remainder of the
region is underlain by Lower Cretaceous "Bentonitic zone" strata and Upper Cretaceous "Bituminous" and "Pale shale zone" strata; these rocks are best exposed along Anderson River. A thin gravel and sand unit of probable Tertiary - Quaternary age caps the plateau on the east side of Anderson River. A
regional unconformity separates the Devonian and Cretaceous successions and a regional disconformity occurs between the Lower and Upper Cretaceous rocks. strata in the map-area dip toward the northwest at low angles. There are few structural complications. A broad, linear arch of preCretaceous age
coincides with Kugaluk River and small, tight, disharmonic folds of non-tectonic origin occur in "Bituminous zone" rocks west of Anderson River.
The geology of the Michikamau Intrusion, Labrador
Authors: Emslie R F
Published: March 2016

The Michikamau Intrusion underlies about 2,OOO square kilometres in west-central Labrador and is one of a group of large anorthositic plutons in the Nain Province. Description of the intrusion and its setting is based chiefly on field observations and is meant to
form a framework for future petrological investigations. The original form of the intrusion was a funnel or lopolith that has since been modified by post- consolidation faulting. The marginal zone consists chiefly of olivine gabbro. The layered series is mainly troctolite and leucotroctolite which
is overlain in turn by a thick anorthosite zone and an upper zone of leucogabbro and gabbro. Transgressive late differentiates are ferrodiorite, ferromonzonite and ferroadamellite . Rhythmic layering and planar plagioclase orientation are widespread and form the basis for structural interpretation.
Layering in both the marginal zone and the layered series is subparallel to the walls and is believed to have formed largely through the action of convection currents. Faults complicate the interpretation but the maximum thickness of the intrusion is estimated to have been in excess of 15 km.. The
Michikamau Intrusion appears to have been emplaced at and near the contact between a granulitic gneiss basement complex and a supracrustal sequence (the Petscapiskau Group). The magma that filled the Michikamau chamber is believed to have been an aluminous basaltic liquid carrying a suspension of
plagioclase crystals. A model is outlined in which, shortly after emplacement, the suspended plagioclase rose to accumulate in the upper part of the chamber and thereafter solidification took place by bottom accumulation of crystals.
Play in Grade R classrooms: Diverse teacher perceptions and practices
Authors: Aronstam Shelley , Braund Martin
Published: March 2016

The study explores the role of play in Grade R classrooms in the Cape Peninsula. The focus is on perceptions of teachers from differing backgrounds regarding how play is supported and utilised in the classroom. Theories of childhood play as propounded by Jean Piaget and Lev Vygotsky provide the theoretical background to our understanding of child play. Data were collected from 104 teachers in 41 primary schools and early childhood development (ECD) centres in both well-resourced and under-resourced environments, using semi-structured interviews and guided observations of practice. It was found that, although play is a difficult concept to define, it is easy to recognise. Teachers at some schools seem to have less knowledge of the pedagogy of play. Insights into early childhood teachers’ views on the role of play in the curriculum have the potential to inform the planning for teacher training and national policy development for early years’ learning. For these reasons, it is necessary to define and understand structured and formal play in the diverse contexts of South Africa, specifically by following, through the years, the teachers who utilise play as pedagogical tool.

Published: March 2016

In 2004, Ethiopia introduced a community-based Health Extension Program to deliver basic and essential health services. We developed a comprehensive performance scoring methodology to assess the performance of the program. A balanced scorecard with six domains and 32 indicators was developed. Data collected from 1,014 service providers, 433 health facilities, and 10,068 community members sampled from 298 villages were used to generate weighted national, regional, and agroecological zone scores for each indicator. The national median indicator scores ranged from 37% to 98% with poor performance in commodity availability, workforce motivation, referral linkage, infection prevention, and quality of care. Indicator scores showed significant difference by region (P < 0.001). Regional performance varied across indicators suggesting that each region had specific areas of strength and deficiency, with Tigray and the Southern Nations, Nationalities and Peoples Region being the best performers while the mainly pastoral regions of Gambela, Afar, and Benishangul-Gumuz were the worst. The findings of this study suggest the need for strategies aimed at improving specific elements of the program and its performance in specific regions to achieve quality and equitable health services.

The 2014–2015 Ebola epidemic has been the most protracted and devastating in the history of the disease. To prevent future outbreaks on this scale, it is imperative to understand the reasons that led to eventual disease control. Here, we evaluated the shifts of Ebola dynamics at national and local scales during the epidemic in Liberia. We used a transmission model calibrated to epidemiological data between June 9 and December 31, 2014, to estimate the extent of community and hospital transmission. We found that despite varied local epidemic patterns, community transmission was reduced by 40–80% in all the counties analyzed. Our model suggests that the tapering of the epidemic was achieved through reductions in community transmission, rather than accumulation of immune individuals through asymptomatic infection and unreported cases. Although the times at which this transmission reduction occurred in the majority of the Liberian counties started before any large expansion in hospital capacity and the distribution of home protection kits, it remains difficult to associate the presence of interventions with reductions in Ebola incidence.
Knowledge of Hepatitis B Transmission Risks Among Health Workers in Tanzania
Authors: Debes Jose D. , Kayandabila Johnstone , Pogemiller Hope
Published: March 2016

Healthcare workers are at increased risk of contracting hepatitis B virus (HBV), particularly in settings of high HBV seroprevalence, such as sub-Saharan Africa. We evaluated HBV knowledge among health-care workers in rural Tanzania by distributing an HBV paper survey in two northern Tanzanian hospitals. There were 114 participants (mean age 33 years, 67% female). Of the participants, 91% were unaware of their HBV status and 89% indicated they had never received an HBV vaccine, with lack of vaccine awareness being the most common reason (34%), whereas 70% were aware of HBV complications and 60% understood routes of transmission. There was a significant difference in knowledge of HBV serostatus and vaccination between participants with a medical background and others, P = 0.01 and 0.001, respectively. However, only 33% of consultants (senior medical staff) knew their HBV serostatus. There was no significant difference between knowledge of HBV transmission routes and occupation. Our study reveals low knowledge of HBV serostatus and vaccination status among hospital workers in Tanzania.

Published: March 2016

The human alphacoronaviruses HCoV-NL63 and HCoV-229E are commonly associated with upper respiratory tract infections (URTI). Information on their molecular epidemiology and evolutionary dynamics in the tropical region of southeast Asia however is limited. Here, we analyzed the phylogenetic, temporal distribution, population history, and clinical manifestations among patients infected with HCoV-NL63 and HCoV-229E. Nasopharyngeal swabs were collected from 2,060 consenting adults presented with acute URTI symptoms in Kuala Lumpur, Malaysia, between 2012 and 2013. The presence of HCoV-NL63 and HCoV-229E was detected using multiplex polymerase chain reaction (PCR). The spike glycoprotein, nucleocapsid, and 1a genes were sequenced for phylogenetic reconstruction and Bayesian coalescent inference. A total of 68/2,060 (3.3%) subjects were positive for human alphacoronavirus; HCoV-NL63 and HCoV-229E were detected in 45 (2.2%) and 23 (1.1%) patients, respectively. A peak in the number of HCoV-NL63 infections was recorded between June and October 2012. Phylogenetic inference revealed that 62.8% of HCoV-NL63 infections belonged to genotype B, 37.2% was genotype C, while all HCoV-229E sequences were clustered within group 4. Molecular dating analysis indicated that the origin of HCoV-NL63 was dated to 1921, before it diverged into genotype A (1975), genotype B (1996), and genotype C (2003). The root of the HCoV-229E tree was dated to 1955, before it diverged into groups 1–4 between the 1970s and 1990s. The study described the seasonality, molecular diversity, and evolutionary dynamics of human alphacoronavirus infections in a tropical region.

Patient-physician communication is an integral part of high-quality patient care and an expectation of the Clinical Learning Environment Review program.Background

 This quality improvement initiative evaluated the impact of an educational audit and feedback intervention on the frequency of use of 2 tools—business cards and white boards—to improve provider identification.Objective

 This before-after study utilized patient surveys to determine the ability of those patients to name and recognize their physicians. The before phase began in July 2013. From September 2013 to May 2014, physicians received education on business card and white board use.Methods

 We surveyed 378 patients. Our intervention improved white board utilization (72.2% postintervention versus 54.5% preintervention, P < .01) and slightly improved business card use (44.4% versus 33.7%, P = .07), but did not improve physician recognition. Only 20.3% (14 of 69) of patients could name their physician without use of the business card or white board. Data from all study phases showed the use of both tools improved patients' ability to name physicians (OR = 1.72 and OR = 2.12, respectively; OR = 3.68 for both; P < .05 for all), but had no effect on photograph recognition.Results

 Our educational intervention improved white board use, but did not result in improved patient ability to recognize physicians. Pooled data of business cards and white boards, alone or combined, improved name recognition, suggesting better use of these tools may increase identification. Future initiatives should target other barriers to usage of these types of tools.Conclusions
Decline of the Black Sea oxygen inventory
Authors: Capet Arthur , Stanev Emil V. , Beckers Jean-Marie , Murray James W. , Grégoire Marilaure
Published: March 2016

Abstract. We show that from 1955 to 2015, the inventory of oxygen in the Black Sea has decreased by 44 % and the basin-averaged oxygen penetration depth has decreased from 140 m in 1955 to 90 m in 2015, which is the shallowest annual value recorded during that period. The oxygenated Black Sea surface layer separates the world's largest reservoir of toxic hydrogen sulfide from the atmosphere. The threat of chemocline excursion events led to hot debates in the past decades arguing on the vertical stability of the Black Sea oxic/suboxic interface. In the 1970s and 1980s, when the Black Sea faced severe eutrophication, enhanced respiration rates reduced the thickness of the oxygenated layer. Re-increasing oxygen inventory in 1985–1995 supported arguments in favor of the stability of the oxic layer. Concomitant with a reduction of nutrient loads, it also supported the perception of a Black Sea recovering from eutrophication. More recently, atmospheric warming was shown to reduce the ventilation of the lower oxic layer by lowering cold intermediate layer (CIL) formation rates. The debate on the vertical migration of the oxic interface also addressed the natural spatial variability affecting Black Sea properties when expressed in terms of depth. Here we show that using isopycnal coordinates does not overcome the significant spatial variability of oxygen penetration depth. By considering this spatial variability, the analysis of a composite historical set of oxygen profiles evidenced a significant shoaling of the oxic layer, and showed that the transient "recovery" of the 1990s was mainly a result of increased CIL formation rates during that period. As both atmospheric warming and eutrophication are expected to increase in the near future, monitoring the dynamics of the Black Sea oxic layer is urgently required to assess the threat of further shoaling.

Published: March 2016

Abstract. This study presents an easy and convenient empirical method to optimize polarimetric variables and produce more accurate dual polarization radar rainfall estimation. Weather Radar Center (WRC) in Korea Meteorological Administration (KMA) suggested relations between polarimetric variables (Z–ZDR and Z–KDP) based on a 2-D Video Distrometer (2DVD) measurements in 2014. Observed polarimetric variables from CAPPI (Constant Altitude Plan Position Indicator) images composed at 1 km of height were adjusted using the WRC's relations. Then dual polarization radar rainfalls were estimated by six different radar rainfall estimation algorithms, which are using either Z, Z and ZDR, or Z, ZDR and KDP. Accuracy of radar rainfall estimations derived by the six algorithms using the adjusted variables was assessed through comparison with raingauge observations. As a result, the accuracy of the radar rainfall estimation using adjusted polarimetric variables has improved from 50 % to 70 % approximately. Three high rainfall events with more than 40 mm of maximum hourly rainfall were shown the best accuracy on the rainfall estimation derived by using Z, ZDR and KDP. Meanwhile stratiform event was gained better radar rainfalls estimated by algorithms using Z and ZDR.
Cumulative areawise testing in wavelet analysis and its application to geophysical time series
Authors: Schulte Justin A.
Published: March 2016

Abstract. Statistical significance testing in wavelet analysis was improved through the development of a cumulative areawise test. The test was developed to eliminate the selection of two significance levels that an existing geometric test requires for implementation. The selection of two significance levels was found to make the test sensitive to the chosen pointwise significance level, which may preclude further scientific investigation. A set of experiments determined that the cumulative areawise test has greater statistical power than the geometric test in most cases, especially when the signal-to-noise ratio is high. The number of false positives identified by the tests was found to be similar if the respective significance levels were set to 0.05.
Biodiversity offsetting in England: governance rescaling, socio-spatial injustices, and the neoliberalization of nature
Authors: Apostolopoulou Evangelia
Published: March 2016

Abstract. In this paper, I use primary empirical data obtained through interviews in selected case studies around England to shed light on the neoliberal character of biodiversity offsetting, its interrelationship with governance rescaling processes, and the way the latter influences the distribution of the costs and benefits of biodiversity offsetting policies. My results show that biodiversity offsetting in England has been a reactionary neoliberal policy whose implementation has so far been characterized by important deficits from an environmental and socio-spatial justice perspective.
Video Links from Prison: Permeability and the Carceral World
Authors: McKay Carolyn
Published: March 2016

As audio visual communication technologies are installed in prisons, these spaces of incarceration are networked with courtrooms and other non-contiguous spaces, potentially facilitating a process of permeability. Jurisdictions around the world are embracing video conferencing and the technology is becoming a major interface for prisoners’ interactions with courts and legal advisers. In this paper, I draw on fieldwork interviews with prisoners from two correction centres in New South Wales, Australia, to understand their subjective and sensorial experiences of using video links as a portal to the outside world. These interviews raised many issues including audio permeability: a soundtrack of incarceration sometimes infiltrates into the prison video studio and then the remote courtroom, framing the prisoner in the context of their detention, intruding on legal process, and affecting prisoners’ comprehension and participation.
Imposed Stories: Prisoner Self-narratives in the Criminal Justice System in New South Wales, Australia
Authors: Hall Maggie , Rossmanith Kate
Published: March 2016

This article examines the ways in which offenders are required to provide very particular accounts of themselves and to self-narrate in confined ways. Drawing on ethnographic fieldwork and interviews conducted in the New South Wales justice system, it explores how the stories that offenders are made to accept and tell about themselves often bear little relationship to their own reflections. It analyses how, despite the expectations of judges and prison authorities, these self-narratives are not products of an offender’s soul-searching concerning his past actions and experience; rather they are products of an official legal narrative being imposed on an offender whose capacity to own and enact such a narrative is already seriously compromised.
Rhetoric, Aboriginal Australians and the Northern Territory Intervention: A Socio-legal Investigation into Pre-legislative Argumentation
Authors: Roffee James A
Published: March 2016

Presented within this article is a systematic discourse analysis of the arguments used by the then Australian Prime Minister and also the Minister for Indigenous Affairs in explaining and justifying the extensive and contentious intervention by the federal government into remote Northern Territory Aboriginal communities. The methods used within this article extend the socio-legal toolbox, providing a contextually appropriate, interdisciplinary methodology that analyses the speech act’s rhetorical properties. Although many academics use sound-bites of pre-legislative speech in order to support their claims, this analysis is concerned with investigating the contents of the speech acts in order to understand how the Prime Minister’s and Minister for Indigenous Affairs’ argumentations sought to achieve consensus to facilitate the enactment of legislation. Those seeking to understand legislative endeavours, policy makers and speech actors will find that paying structured attention to the rhetorical properties of speech acts yields opportunities to strengthen their insight. The analysis here indicates three features in the argumentation: the duality in the Prime Minister’s and Minister’s use of the Northern Territory Government’s Little Children are Sacred report; the failure to sufficiently detail the linkages between the Intervention and the measures combatting child sexual abuse; and the omission of recognition of Aboriginal agency and consultation.
First year Business students’ perceptions of academic support through embedding. A Practice Report
Authors: De Maio Carmela , Desierto Anibeth
Published: March 2016

This paper explores the perceptions of first year Business students to embedding sessions and additional support workshops offered through a collaboration between learning advisors and lecturers in a first year foundational unit. Through a social constructivist lens and utilising action research methods, questionnaires (n=42) were administered to two cohorts of students at the conclusion of the unit in 2011 and 2012 to explore firstly, whether or not they perceived the embedding sessions to be of benefit and, secondly, whether having the learning advisor in the class made them more likely to utilise additional support outside class time. In addition, the researchers sought to explore whether there were any improvements in students’ final results which might be attributable to the academic support offered to them through the embedding sessions. The findings from the quantitative and qualitative data suggest that the students perceived the embedding workshops as having positive effects on their academic literacy skills.  Furthermore, there was a slight increase in the number of students that sought additional support outside of class time.  However, it appears that the embedding workshops did not lead to an improvement in students’ final marks for the unit and this is an area which requires further investigation.

Татмын нуга нь ус чийгийн хангамж ихтэй, илүүдэл устай нөхцөл учраас биомассын өөрчлөлтөнд хур тунадаснаас илүү агаарын температур тэргүүн зэргийн нөлөөлөх хүчин зүйл болж байна. Харин хашааны гаднах бүлгэмдлийн биомассыг хашсан бүлгэмдлийн биомасстай харьцуулахад 1,2 дахин бага биомасс бүрдүүлсэн байв. Өөрөөр хэлбэл малын бэлчээрт их ашиглагдсан нугын бүлгэмдлийг хашиж хамгаалахад бүлгэмдлийн бүтэц бүрэлдэхүүн сайжирч, биомасс нэмэгдэх бичил орчин бүрддэг байна. Татмын нугын бүлгэмдлийн биомассын хэмжээ, цаг уурын үзүүлэлт хоорондын корряляцийг бодоход агаарын температураас (R=0.816) шууд, хур тунадаснаас (R=0.47772) сул хамаарч байв.

2013 оны байдлаар Монгол улсын нийслэл Улаанбаатар хотын хүн ам нь 1 сая 230 мянга болон өсч, өдрөөс өдөрт өргөжин тэлсээр байгаа юм. Улс орон хурдацтай хөгжихийн зэрэгцээ хотжилт, эдийн засгийн төвлөрөл эрчимтэй явагдаж байна. Энэ нь нийслэл хотын хөгжлийг хурдасган дэлхийн хөгжилтэй хотуудын зэрэглэлд ойртуулах сайн талтай боловч байгалийн элдэв гамшигт үзэгдэлд өртөх магадлалыг ихэсгэх хандлагатай байдаг. 1994-2000 онд Улаанбаатар хот орчимд газар хөдлөлтийг бүртгэх өндөр мэдрэмжтэй орчин үеийн тоон бичлэгтэй суурин станцыг байгуулснаар Улаанбаатар хотоос эргэн тойрон 100 км радиус бүхий орчинд болж буй газар хөдлөлтийн горим, ерөнхий төлөв байдлыг нарийвчлан судалж эхэлсэн. Харин 2005 оноос Улаанбаатар хот орчмын бүс нутагт газар хөдлөлтийн идэвхжилт өндөр ажиглагдаж байгаа бөгөөд идэвхжилтийн бүс нутагт хийгдсэн нарийвчилсан судалгааны үр дүнд Улаанбаатар хот орчимд хэд хэдэн хүчтэй газар хөдлөлтийн идэвхтэй голомт буюу хагарлын бүс байгааг тогтоосон. Эдгээр идэвхтэй хагарлуудаас газар хөдлөлтийн идэвхжилт сүүлийн жилүүдэд их явагдаж буй Эмээлтийн хагарлын бүс нутагт 2010 оноос эхлэн Франц, ОХУ-ын судлаачдын хамт геологи геофизикийн судалгаа явуулсан байдаг. судалгааны үр дүнгээс хархад Эмээлтийн хагарал нь Улаанбаатар хотын баруун хэсэгт хил залган Эмээлт өртөөнөөс баруун хойш 13 км орчим зайнд зүүн урагшаа 1500N азимутын чиглэлд оршиж байна гэж тогтоосон байна.. Мөн хагарлын газрын гадаргуу дээр болон сансрын зурагт илрүүлсэн хэсэг нь 5 км орчим бөгөөд 2005 оноос эхлэн ажиглагдаж буй газар хөдлөлтийн идэвхжилт, геофизикийн хэмжилтүүдийн үр дүнг үндэслэн хагарлын уртыг 35 км тогтоосон. Эмээлтийн хагарал дээр магнитуд нь 7.0 хүчтэй газар хөдлөлт болох боломжтой гэж үнэлсэн байна. [1], [2] Газар хөдлөлтийн аюулыг багасгах нэг арга нь тухайн бүс нутагт үүсч болзошгүй газар хөдлөлтийн чичирхийллийг үнэлэх түүнд тэсвэртэй барилга байгууламж барих явдал юм. Орчин үед барилгын дизайн хийхийн тулд хүчтэй газар хөдлөлтийн загварчилсан бичлэгийг өргөн хэрэглэдэг болсон. Манай улсын хувьд одоогоор яг өөрийн оронд тооцоолон гаргасан бичлэг хэрэглэдэггүй байна. Бид энэхүү ажлаар Стохастик Грин функцийн аргыг ашиглан Эмээлтийн хагарал дээр хүчтэй газар хөдлөлт болоход голомтоос ирэх газар хөдлөлтийн синтетик сейсмограмыг Улаанбаатар хотын талбайн хувьд тооцон гаргах зорилго тавин ажилласан. Уг ажлыг гүйцэтгэхдээ бид хотын талбайг хадан хөрс гэж үзэн тооцооллыг хийсэн бөгөөд орчны геологийн нөхцөлийг тооцоонд оруулаагүй болно. Энэ чиглэлийн судалгааг 2011 онд хийсэн Одонбаатарын ажлаас харж болно. [3]Энэхүү синтетик сейсмограмыг тооцон гаргаснаар Улаанбаатар хотын газар хөдлөлтийн аюулыг үнэлэх цаашид барилгын норм дүрэмд тусган оруулах чухал ач холбогдолтой юм.

Уул уурхайн гаралтай тэсэлгээнээс бий болсон сейсмо-акустик сигнал нь “Инфра авианы” станцыг суурилуулсанаас хойш тасралтгүй бүртгэгдэж байна. Сейсмик болон сейсмо-акустик сигналыг хамтруулан боловсруулж, мэдээллийн санд анализ хийснээр тухайн тэсэлгээний эхэлсэн хугацаа, газар зүйн байршил, зай, чиглэл зэрэг параметрүүдийг тодорхойлдог. Инфра авианы станцад өвөл болон зуны улиралд уурхайгаас ирэх тэсэлгээний акустик сигнал нь харилцан адилгүй бүртгэгдэж байсан. Энэхүү ажлаар харилцан адилгүй бүртгэгдэх шалтгааныг тодорхойлохын тулд сигналын спектрийн түвшинг магадлалаар тодорхойлох аргазүй боловсруулсан. Бидний хийсэн судалгаагаар инфра авианы станцад бүртгэгдэж байгаа акустик долгионы шуугианы түвшин өвлийн улиралд 25-30дБ байхад зун нь 30-40дБ болж нэмэгдэж байлаа. Энэхүү шуугианы түвшингийн өвөл, зуны улиралын ялгаа нь тэсэлгээний сигнал бүртгэх түвшинд нөлөөлөх гол параметр болох нь тодорхойлогдсон болно.

LIFE CYCLES AND SECONDARY PRODUCTION OF EPHEMEROPTERA, PLECOPTERA, AND TRICHOPTERA (INSECTA) UNDER AN EXTREME CONTINENTAL CLIMATE (RIVER KHARAA, MONGOLIA)
Authors: Saulyegul A
Published: March 2016

There are still knowledge gaps and uncertainties concerning the research of macroinvertebrates, in particular, a life cycle study of representative species are one such section of information missing in Mongolia. Therefore, this study was conducted within the framework of the biomonitoring program in the Kharaa River Basin under the research aims of the project entitled ‘Integrated Water Resources Management (IWRM) in Central Asia: Model Region Mongolia (MoMo)’. This study provided the first quantitative results on the life cycle, production, growth rate and emergence of aquatic insects from Mongolia, to allow comparisons with studies in other regions using the same methods. The 3-year study (2007-2009) of the life cycles of eighteen selected species according to the larval body size distribution and emergence period showed that the life cycle strategies in Ephemeroptera, Plecoptera, and Trichoptera and their production in the Kharaa River Basin clearly indicated adaptations to the harsh environmental conditions with strict univoltinism and low secondary production. In conclusion, it is essential to obtain knowledge especially about life cycle strategies of macroinvertebrates to predict re-colonisation potential of disturbed habitats and to evaluate the efficiency of management measures.
The Information Needs of School-based Speech–Language Pathologist Assistants: A Case Study
Authors: Betts Shea Matthew
Published: March 2016

Speech–language pathologists (SLPs) are professionals who specialize in diagnosing and treating communication disorders. They are sometimes supported by a speech–language pathologist assistant (SLPA), who engages in treatment procedures under the guidance of the supervising SLP. Both the qualifications needed to practice as well as the scope of responsibilities vary for SLPAs depending on jurisdiction. Notably, these assistants can play a central role in the treatment of speech disorders. Research regarding the information needs of SLPAs, however, is limited. This paper seeks to explore the information resources and services available to a particular SLPA community and to examine the obstacles to meeting its information needs. An interview with a practicing school-based SLPA is used to discuss current practices and suggest improvements to information services available to SLPA communities. This interview highlights some of the challenges that may be faced by school-based SLPAs when seeking information, and it provides an opportunity to consider context-specific solutions to these issues.

http://dx.doi.org/10.5902/1980509818411Por fazer parte de inúmeros compostos e estar diretamente relacionado com a capacidade fotossintética das plantas, o nitrogênio (N) pode influenciar significativamente na produção e enraizamento de estacas. Com base nesse contexto, o trabalho teve por objetivo avaliar o efeito de doses crescentes de N na produtividade, capacidade e velocidade de enraizamento das miniestacas produzidas de minicepas do clone híbrido de Eucalyptus grandis x Eucalyptus urophylla (I-224), além da qualidade das mudas formadas. O presente trabalho foi realizado no viveiro de mudas clonais de Eucalyptus, em minijardim de leito de areia da FAEF – Garça – SP. O delineamento experimental utilizado foi o inteiramente casualizado com 4 repetições, sendo os tratamentos constituídos por 5 doses de nitrogênio diferentes na solução nutritiva (0; 80; 160; 240 e 320 mgL-1). As variáveis analisadas foram: número de estacas produzidas, índice de produtividade, enraizamento das estacas produzidas e determinação da massa seca das mudas. A dose de nitrogênio aplicada no minijardim influenciou na produção de estacas, apresentando comportamento quadrático, atingindo a produção máxima (13,1 estacas cepa-1 mês-1) com a dose estimada de 129 mg L-1. O percentual de enraizamento apresentou comportamento linear crescente. A dose que proporcionou o maior índice de produtividade do minijardim foi de 194 mg L-1. A dose de nitrogênio aplicada no minijardim influenciou significativamente na velocidade de enraizamento, e o acúmulo de matéria seca das mudas formadas.

http://dx.doi.org/10.5902/1980509818445A podridão-de-raízes da erva-mate, causada por Fusarium spp., Rhizoctonia sp. e Pythium sp., é a principal doença da cultura e causa sérios prejuízos em viveiro e a campo. No entanto, existem poucos estudos referentes à epidemiologia dessa doença. Assim, o presente trabalho teve por objetivo estudar e descrever os principais aspectos epidemiológicos relacionados à podridão-de-raízes da erva-mate em viveiro e a campo. Para isso, foram demarcados para estudo ervais e viveiros localizados na região alta do Vale do Taquari - RS, nos quais se procedeu a coleta de flores, frutos, sementes, plântulas, mudas e substrato para análises laboratoriais. Observou-se que as flores podem ser a porta de entrada dos patógenos no patossistema, pois 80% delas apresentaram contaminação por Fusarium sp. e 15% por Rhizoctonia sp. Além disso, o método de obtenção e estratificação das sementes, utilizado pelos viveiristas, contribuem para o aumento da contaminação, chegando a 100% das sementes no momento da semeadura. Observou-se, também, que as mudas podem estar contaminadas, mesmo não apresentando sintomas e, ao serem replantadas a campo, venham a contaminar áreas livres dos patógenos. Os testes de patogenicidade com alguns isolados mostraram sua capacidade em causar a doença.

http://dx.doi.org/10.5902/1980509818451A maioria das Unidades de Conservação (UCs) de Curitiba (PR, Brasil) está contaminada por espécies arbóreas exóticas invasoras (AEIs). Mas não existem estudos que evidenciem seu impacto e manejo apropriado. Os objetivos dessa pesquisa foram avaliar a participação das AEIs e as implicações e manejo da AEI de maior importância estrutural na composição florística-estrutural do Parque da Barreirinha, um remanescente de Floresta com Araucária. Foram avaliadas quatro unidades amostrais, com área total de 1600 m² representando aproximadamente 4% da área total do maciço vegetal. Foram amostrados 354 indivíduos arbóreos, com DAP ≥ 15 cm, e calculados, para cada espécie amostrada, os parâmetros de frequência relativa, densidade relativa, dominância relativa e valor de importância. Foram identificadas 29 famílias, 43 gêneros e 57 espécies, sendo três AEIs. A sustentabilidade e a integridade desta UC podem estar comprometidas devido à presença de Pittosporum undulatum Vent. (pau-incenso), espécie de maior valor de importância estrutural, alta densidade e frequência. Pelas características botânico-ecológicas do Pittosporum undulatum, a opção de remoção de indivíduos adultos deve ser considerada com muita cautela.

http://dx.doi.org/10.5902/1980509818462O objetivo da pesquisa foi avaliar a eﬁciência do preservativo CCB na melhoria da resistência de duas espécies de bambu (Bambusa vulgaris e Dendrocalamus giganteus) à ação de cupins e coleópteros xilófagos. As hastes de bambu coletadas nas proximidades dos municípios de Alegre e Jerônimo Monteiro, sul do Espírito Santo, foram transformadas em colmos de 2,0 m de comprimento e tratadas em solução de 1 ou 3% de ingredientes ativos (i.a.) do produto comercial “MOQ OX 50”, à base de cobre, cromo e boro (CCB). Os métodos de tratamento empregados foram os de transpiração radial (diafragma integro e rompido), imersão prolongada e Boucherie modificado. Nos métodos por transpiração radial e imersão prolongada, os colmos foram expostos nas soluções por períodos de 5, 10 ou 15 dias, já no método de Boucherie modificado não houve segregação entre os tempos de tratamento. Para avaliar a eficiência dos métodos, foram retiradas amostras na posição a 50 cm da base dos colmos. Nos ensaios foram utilizados térmitas do gênero Nasutitermes sp. e o coleóptero Dinoderus minutus. A partir das análises dos resultados obtidos, foi verificado que, as duas espécies de bambu tratadas apresentaram alta resistência ao ataque dos cupins e coleópteros, e inclusive as amostras não tratadas apresentaram baixa perda de massa quando submetidas aos ensaios.
