Analysis of the variables: Commodity price and discount rate on long-term open pit mine planning
Authors: Fontes MP  , Koppe JC  , Silva Neto JA
Published: March 2021

Long-term open pit mine planning is a complex process which deals with numerous uncertainties, whether they are economical (commodity price, operational costs, production schedule, discount rate, inflation, among others); geological (grade distribution, density, hardness, etc); or physical constraints (property limits, environmental issues, legislation, etc). In this context, this paper aims to evaluate the effects of the variation of two important variables: commodity price and discount rate, with regard to the economic criterion, represented by the Net Present Value (NPV) of the mining business. Starting from a baseline value of US$ 80/t, the commodity (phosphate rock was used as a case study) price was varied within a 50% range, above and below the baseline value, obtained from historic values from the last 5 years. The discount rate values adopted in the analyses were 6%, 8%, 10%, 12%, 14%, 16%, 18% and 20%. The results showed increases in the market price yielded higher NPV and life of mine values. On the other hand, it was noted that increases in the discount rate can significantly alter the NPV, materially reducing the value of the mining undertaking. It is also worth noting that, in contrast to more robust approaches such as Real Options Theory (ROT), traditional Discounted Cash Flow (DCF) methods, such as NPV, assume variables, such as commodity price, to be fixed, which could either lead to the undervaluation or overvaluation of a project.
O CONTEXTO, O SOCIAL E A QUESTÃO DO SUJEITO LÍRICO EM GLAUCO MATTOSO
Authors: Alves dos Santos Ricardo
Published: March 2021

Nesta reflexão, propomos uma avaliação do contexto de produção artística do poeta Glauco Mattoso alinhada à constituição do sujeito lírico edificado no projeto dele. Para tanto, à princípio, discorremos sobre o panorama crítico acerca da literatura contemporânea, buscando refletir sobre algumas direções críticas e teóricas sobre as produções líricas da atualidade. Além disso, buscamos a ressonância do que se considera “literatura marginal” na poesia de Glauco Mattoso, na qual observamos um elo entre vida e obra na tessitura artística do autor. Por fim, analisamos dois sonetos de Glauco Mattoso: “Formal” e “Convicto”, na tentativa de perceber o quanto o trabalho realizado pelo poeta se revela como uma poesia de resistência que carrega em seu bojo criativo um deslocamento dos princípios tradicionais e conservadores acerca da arte e da vida.

KONSTRUKSI GENDER MELALUI PENGGAMBARAN ALAM DALAM PUISI POST SCRIPTUM KARYA TOETY HERATY DAN THE SNAKE CHARMER KARYA SAROJINI NAIDU
Authors: Basri Syaiful Qadar
Published: March 2021

AbstrakÂ Â Â Â Â Â Â Â Â Â Â  Perempuan dianggap memiliki hubungan spesial dengan alam. Hubungan spesial tersebut dapat dilihat dalam kata Ibu Pertiwi. Kata Pertiwi memiliki arti Bumi dan disandingkan dengan kata Ibu sebagai sebuah ungkapan yang menunjukkan perempuan sering dikaitkan dengan alam. Kedekatan tersebut dapat dianggap sebagai sebuah anugerah sekaligus bentuk stereotip. Tulisan ini menganalisis dua puisi Post Scriptum karya Toety Heraty dan The Snake Charmer karya Sarojini Naidu. Melalui dua karya tersebut, penulis akan melihat bagaimana perempuan dikaitkan dengan alam melalui representasi alam, sehingga dapat menjawab apakah kedekatan perempuan dan alam merupakan konstruksi sosial ataukah bentuk yang seharusnya disyukuri. Dari hasil analisis, peneliti menemukan bahwa hubungan perempuan dan alam dalam puisi Post Scriptum merupakan hal yang tidak patut untuk dirayakan. Pengaitan alam dan perempuan menunjukkan adanya operasi kuasa niliai-nilai sosial (Cultural Ecofeminism). Sedangkan pada puisi The Snake Charmer, peneliti menemukan bahwa hubungan alam dan perempuan merupakan hal istimewa yang menunjukkan keagungan dan kesucian perempuan (Essentialism Ecofeminism). Dalam konteks ini, analisis kedua puisi dikaitkan dengan konteks budaya yang melatarbelakangi penulisan karya.Kata Kunci: Ecofeminisme, Gender

New Perspectives on Henry Ludwell Moore’s Use of Harmonic Analysis
Authors: Turner Paul , Wood Justine
Published: March 2021

This paper reconsiders the contribution of Henry Ludwell Moore to dynamic economics through the use of harmonic analysis. We show that Moore’s analysis is innovative in its use of the Fourier transformation for the identification of cycles with different periodicities. This enables Moore to identify cycles of longer length with more precision than would be the case for the standard methodology. We are able to replicate the main features of his results and confirm the existence of a rainfall cycle with a periodicity similar to that of the business cycle (eight years). However, we find that the evidence for a longer (thirty-three year) rainfall cycle is weaker than Moore indicates. We also argue that a central theme of Moore’s analysis, the relationship between rainfall, agricultural productivity and the business cycle, marks an early precursor of the ‘Real Business Cycle’ approach. Stigler’s (1962) dismissal of Moore’s work on cycles as ‘a complete failure’ is therefore, in our opinion rather unfair. Instead, we argue that, although his work is certainly flawed, it nevertheless deserves a place in both the history of business cycle theory and empirical economics.

HMMR is differentially expressed in lymph node metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: March 2021

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the breast and the brain reside the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that the hyaluronan mediated motility receptor, HMMR, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. HMMR mRNA was present at increased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of HMMR in primary tumors of the breast was correlated with patient distant metastasis-free survival. Modulation of HMMR expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.

Implicitly learning when to be ready: from instances to categories
Authors: Kruijne Wouter , Galli Riccardo Mattia , Los Sander
Published: March 2021

[This article has been accepted for publication as a brief report for Psychonomic Bulletin & Review (https://www.springer.com/journal/13423) ]There is growing appreciation for the role of long-term memory in guiding temporalpreparation in speeded reaction time tasks. In experiments with variable foreperiodsbetween a warning stimulus (S1) and a target stimulus (S2), preparation is affected byforeperiod distributions experienced in the past, long after the distribution has changed.These effects from memory can shape preparation largely implicitly, outside of participants’awareness. Recent studies have demonstrated the associative nature of memory-guidedpreparation. When distinct S1s predict different foreperiods, they can trigger differentialpreparation accordingly. Here, we propose that memory-guided preparation allows foranother key feature of learning: the ability to generalize across acquired associations andapply them to novel situations. Participants completed a variable foreperiod task where S1was a unique image of either a face or a scene on each trial. Images of either category werepaired with different distributions with predominantly shorter versus predominantly longerforeperiods. Participants displayed differential preparation to never-before seen images ofeither category, without being aware of the predictive nature of these categories. Theycontinued doing so in a subsequent Transfer phase, after they had been informed that thesecontingencies no longer held. A novel rolling regression analysis revealed at a fine timescalehow category-guided preparation gradually developed throughout the task, and thatexplicit information about these contingencies only briefly disrupted memory-guidedpreparation. These results offer new insights into temporal preparation as the product of alargely implicit process governed by associative learning from past experiences.
Trauma Spillover in Social Networks
Authors: Sadish
Published: March 2021

Internet searches indicative of mental disorders increased in US counties when COVID-19 casualties rose in other places--- inside and outside US borders--- with which they had strong ties over social media. Casualties within counties or in their vicinity, the stringency of COVID-19 response policies, and the seasonality of affective disorders do not account for the association; nor do characteristics fixed to counties or time. Social ties as defined by migration confirm the association. The results merit attention because internet search behavior predicts emergency department visits.

Published: March 2021

In this Chapter we first look at the core view of the biology of language associated with Minimalism, including the Biolinguistics Program (section 2). Next, we consider research on the brain (section 3) and genetics (section 4), associated with this framework. Finally, we introduce some subsequent views of language evolution which break away from the saltationist, discontinuous nature of the mainstream approach (section 5), and draw some conclusions regarding future prospects (section 6).
The quest for acceptance: a blog-based study of autistic women's experiences and well-being during the identification and diagnosis of their autism
Authors: Harmens Miriam , Sedgewick Felicity , Hobson Hannah
Published: March 2021

Introduction: Mental wellbeing and the female experience are important research topics in the field of autism, and appear to interact, with autistic women appearing to show poorer outcomes in their wellbeing compared to men. Methods: Autistic women’s experiences of coming to recognise and understand their autism were explored, using data collected from blogs written by autistic women about their diagnostic or self-identification experiences. We were particularly interested in wellbeing, and how this contributed to, was affected by, and interacted with the identification and diagnostic process. Blogs from twenty bloggers were submitted to a thematic analysis. Results: The issue of acceptance was a strong central issue, under which we developed themes of self-understanding and self-acceptance, being understood and accepted by others (including peers, clinicians, and others in the autism community), and the exhaustion resulting from trying to be accepted and be understood, including when going through the diagnostic process, and after receiving a formal diagnosis. Conclusions: Diagnosis and identification have both positive and negative effects on autistic women’s well-being, with difficulties following diagnosis stemming from facing male stereotypes of autism. We consider the implications of our findings for clinicians, researchers and those that work with autistic women.
The effects of information utility and teachers’ knowledge on evaluations of under-informative pedagogy across development
Authors: Bass Ilona , Bonawitz Elizabeth , Hawthorne Daniel , Vong Wai Keen , Goodman Noah D. , Gweon Hyowon
Published: March 2021

Teaching is a powerful way to transmit knowledge, but with this power comes a hazard: When teachers fail to select the best set of evidence for the learner, learners can be misled to draw inaccurate inferences. Evaluating others' failures as teachers, however, is a nontrivial problem; people may fail to be informative for different reasons, and not all failures are equally blameworthy. How do learners evaluate the quality of teachers, and what factors influence such evaluations? Here, we present a Bayesian model of teacher evaluation that considers the utility of a teacher's pedagogical sampling given their prior knowledge. In Experiment 1 (N=1168), we test the model predictions against adults' evaluations of a teacher who demonstrated all or a subset of the functions on a novel device. Consistent with the model predictions, participants' ratings integrated information about the number of functions taught, their values, as well as how much the teacher knew. Using a modified paradigm for children, Experiments 2 (N=48) and 3 (N=40) found that preschool-aged children (2a, 3) and adults (2b) make nuanced judgments of teacher quality that are well-predicted by the model. However, after an unsuccessful attempt to replicate the results with preschoolers (Experiment 4, N=24), in Experiment 5 (N=24) we further investigate the development of teacher evaluation in a sample of seven- and eight-year-olds. These older children successfully distinguished teachers based on the amount and value of what was demonstrated, and their ability to evaluate omissions relative to the teacher’s knowledge state was related to their tendency to spontaneously reference the teacher's knowledge when explaining their evaluations. In sum, our work illustrates how the human ability to learn from others supports not just learning about the world but also learning about the teachers themselves. By reasoning about others' informativeness, learners can evaluate others' teaching and make better learning decisions.
Identifying cultural differences in metacognition
Authors: van der Plas Elisa , Zhang Shiqi , Dong Keer , Bang Dan , LI Jian , Wright Nicholas , Fleming Stephen M
Published: March 2021

Aspects of human metacognition such as the ability to consciously evaluate our beliefs and decisions are thought to be culturally acquired. However, direct evidence for this claim is lacking. As an initial step towards answering this question, here we examine differences in metacognitive performance between populations matched for occupation (students), income, demographics and general intelligence, but drawn from two distinct cultural milieus (Beijing, China and London, UK). We show that Chinese participants have heightened metacognitive evaluation of perceptual decision-making task performance in comparison with UK participants. These differences manifested in boosts to post-decisional processing following error trials, de-spite no differences in first-order performance. In a second experiment, we directly replicate these findings and show that a metacognitive advantage generalizes to a new task that replaces post-decision evidence with equivalent social advice. Together, our results are consistent with a proposal that metacognitive capacity is shaped via socio-cultural interactions.

Authors: Hutchison Clare MD , Elmahgoub Fatima , Cave Victoria
Published: March 2021

Introduction: To investigate the quality of information offered by videos on YouTube™ for those individuals seeking information regarding risks associated with orthodontic treatment. The quality of information was compared the British Orthodontic Society (BOS) patient information leaflet ‘Orthodontic treatment- what are the risks’.

Materials and Method: YouTube™ was searched systematically for videos on orthodontic treatment risks using the terms ‘orthodontic risks’ and ‘braces risks’. Videos were selected based on a strict inclusion and exclusion criteria and demographics recorded. Completeness was assessed using a 8-point score based on the BOS patient information leaflet ‘Orthodontic treatment- what are the risks’. Descriptive statistics and statistical analysis using correlation tests were generated.

Result: 19.2% videos met the specified criteria with 80.8% videos excluded. Videos varied in regards to completeness with the mean completeness score of 3 and only 13% meeting all criteria. The risk of pain and discomfort was most commonly included orthodontic risk 61%. No statistical significance was found for completeness of the video with viewers interaction (R = 0.2665, P=0.219897) viewing rate (R=0.1138, P=0.617326) or length of video (R=0.0062, P= 0.977601).

Conclusion: YouTube™ generally hosts videos with low completeness with regards to orthodontic treatment risks. Therefore, orthodontists should be aware of this resource and caution patients regarding the comprehensiveness of information. In addition to the potentially misleading content which is avail-able within YouTube™ videos

Introduction: In past few years, there is huge improvement in orthodontics. Different innovation in orthodontics made the procedure easier and less time consuming. Application of laser is one of them. Many types of dental lasers are currently available that can be efficiently used for soft and hard tissue applications in the field of orthodontics. Two types of lasers are there. One is hard tissue laser, and another is soft tissue laser. Laser therapy is advantageous because it often avoids bleeding, can be pain free, is non‑invasive and is relatively quick. The high cost is its primary disadvantage. The purpose of this article is to provide an overview regarding safe and proper use of soft-tissue lasers in orthodontics

Published: March 2021

This research was conducted because the performance of employees at PT Mora Telematics Indonesia is not optimal so it is suspected that there is an effect of compensation on employee performance at PT Mora Telematics Indonesia Jakarta. This research uses a quantitative approach with correlational research. The study population was 150 employees with a sample of 60 respondents who were taken using simple random sampling technique and data collection techniques using a questionnaire. Simple Linear Regression and Hypothesis Testing were used in this study. Based on the results of the analysis, it is known that there is a positive and significant influence between compensation and performance. Thus H1 is accepted and H0 is rejected.
