Recent Euro-area Inflows into U.S. Bonds: Reconciling and Understanding New Data Sources
Authors: Bertaut Carol C. , Judson Ruth A.
Published: February 2018

In this note we review the data on U.S. cross-border financial flows and positions with a focus on one question of current interest: have euro-area investors been increasing their holdings of U.S. securities since the possibility of European Central Bank quantitative easing (ECB QE) emerged in the latter half of 2014? The prospect of ECB QE, combined with the prospect of U.S. policy rate liftoff, suggested that U.S. interest rates would soon exceed euro-area rates by a wide margin, which might have provided an incentive for euro-area investors to seek higher-yielding U.S. assets, especially bonds. We note that, while some indicators suggest that financial flows from the euro area have been flat or even negative, our view is that the most reliable data indicate that euro-area purchases of U.S. bonds have strengthened, and were particularly strong in early 2015.
Debt Statistics a la Carte: Alternative Recipes for Measuring Government Indebtedness
Authors: Dias Daniel A. , Wright Mark L. J.
Published: February 2018

In this note, we apply our same measurement techniques to the debts of Greece, Ireland and Portugal and show that plausible alternative measures of indebtedness suggest that Greece is anywhere from as much as 50% more indebted, to as little as half as indebted as either Portugal or Ireland. We argue that most reasonable measures imply that Greece is far less indebted than is commonly reported, and that indebtedness levels across these three economies are roughly similar.
The Slowdown in Global Trade

The slowdown in trade has received a great deal of attention, and it is sometimes cited as one of the reasons for the sluggishness of global output growth. However, the linkage between the two is not clear-cut.
Predicting Fed Forecasts
Authors: Ericsson Neil R.
Published: February 2018

Monetary policy decisions by the Fed's Federal Open Market Committee (FOMC) have attracted considerable attention in recent years, especially with quantitative easing through large-scale asset purchases, the introduction of forward guidance, and December's "lift-off" after seven years of a near-zero federal funds rate. The FOMC's decisions are based in part on the Greenbook forecasts, which are economic forecasts produced by the Federal Reserve Board's staff and which are presented to the FOMC prior to their policy meetings. This note shows that the minutes of the FOMC meetings--and the information in those minutes about the Greenbook forecasts--provide valuable insights into the decision-making process of the FOMC.
Low-for-Long Interest Rates and Net Interest Margins of Banks in Advanced Foreign Economies
Authors: Claessens Stijn , Coleman Nicholas S. , Donnelly Michael S.
Published: February 2018

This note explores the empirical evidence between changes in interest rates and NIMs for different interest rate environments to discover the potential adverse effects of a low interest rate on bank NIMs. Using cross-country evidence can be insightful to assess a situation that is not so common in any individual country. Overall, the new empirical analysis shows that low rates are contributing to weaker NIMs and identifies an adverse effect that is materially larger when interest rates are low. It suggests that these effects can be material for banks in some key advanced foreign economies (AFEs).

Financing Affordable and Sustainable Homeownership with Fixed-COFI Mortgages
Authors: Passmore Wayne , von Hafften Alexander H.
Published: February 2018

The 30-year fixed-rate fully amortizing mortgage (or “traditional fixed-rate mortgage”) was a substantial innovation when first developed during the Great Depression. However, it has three major flaws. First, because homeowner equity accumulates slowly during the first decade, homeowners are essentially renting their homes from lenders. With this sluggish equity accumulation, many lenders require large down payments. Second, in each monthly mortgage payment, homeowners substantially compensate capital markets investors for the ability to prepay. The homeowners might have better uses for this money. Third, refinancing mortgages is often very costly. Expensive refinancing may prevent homeowners from taking advantage of falling rates. To resolve these three flaws, we propose a new fixed-rate mortgage, called the Fixed-Payment-COFI mortgage (or “Fixed-COFI mortgage”). This mortgage has fixed monthly payments equal to payments for traditional fixed-rate mortgages and does not require a down payment. Also, unlike traditional fixed-rate mortgages, Fixed-COFI mortgages do not bundle mortgage financing with compensation paid to capital markets investors for bearing prepayment risks; instead, this money is directed toward lower monthly payments or toward purchasing the home. The Fixed-COFI mortgage exploits the often-present prepayment-risk “wedges” between the fixed-rate mortgage rate and the estimated cost of funds index (COFI) mortgage rate. In addition, the Fixed-COFI mortgage is a highly profitable asset for many mortgage lenders. We discuss two variations of the Fixed-COFI mortgage. Homeowners with “affordable” Fixed-COFI mortgages are rebated the “wedges” between the traditional fixed-rate mortgage payments and the COFI mortgage payment. After the “wedges” are rebated, these homeowners may pay substantially less to purchase their homes in 30 years than homeowners with traditional fixed-rate mortgages. This mortgage design may help alleviate housing affordability pressures in many areas of the United States. The other variation of Fixed-COFI mortgage is the “homeownership” Fixed-COFI mortgage. With the “homeownership” Fixed-COFI mortgage, the homeowner commits to a savings program based on the difference between fixed-rate mortgage
Top Income Concentration and Volatility
Authors: Thompson Jeffrey , Parisi Michael , Bricker Jesse
Published: February 2018

Measures of income concentration—such as the share of income received by the highest income families—may be biased by pro-cyclical volatility in annual income. Permanent income, though, can smooth away such volatility and sort families by their usual economic resources. Here, we demonstrate this bias using rolling 3-year panels of IRS tax records from 1997 to 2013 as a proxy for permanent income. For example, one measure of 2012 income concentration—the share of income received by the top 0.1 percent—falls from 11.3 percent to 8.9 percent when families are organized by permanent income instead of annual income. However, the growth in income concentration cannot be explained by this volatility, as growth rates are comparable in the permanent income and annual income groupings during our sample period. Further, the probability of remaining in the highest income groups, while relatively low at the very top of the distribution, increased slightly during our sample period, suggesting that top incomes have become less volatile in this dimension. These results are confirmed using household income data measured in the Survey of Consumer Finances (SCF)—a household survey with a large oversample of high-income households and a unique measure of permanent income.
ДЕМИНЕРАЛИЗАЦИЯ РАСТВОРА ФЕНИЛАЛАНИНА ЭЛЕКТРОМЕМБРАННЫМИ МЕТОДАМИ
Authors: Харина Анастасия Юрьевна , Елисеев Сергей Яковлевич
Published: February 2018

Исследованы параметры эффективности деминерализации растворов алкилароматической аминокислоты – фенилаланина (Phe) и хлорида натрия при использовании методов электродиализа (ЭД) и электродеионизации (ЭДИ). Показаны преимущества турбулентного режима течения жидкости над ламинарным, выражающиеся в достижении больших значений степени обессоливания (D). Способ очистки растворов аминокислоты методом ЭДИ может быть использован как более энергосберегающий, так как при плотностях тока, не превышающих предельную, достигаются значения D больше 70%. ЭДИ также позволяет провести глубокое обессоливание раствора фенилаланина в интенсивных токовых режимах, однако, потери целевого продукта при этом увеличиваются.

Published: February 2018

Выявлены и объяснены закономерности сорбции гидрохлорида пиридоксина на глауконите. Изотермы сорбции проанализированы с применением теорий Ленгмюра, Фрейндлиха, Редлиха-Петерсона и Брунауэра-Эммета-Теллера (БЭТ). Установлено, что процесс сорбции включает в себя локализацию катиона пиридоксина у отрицательно заряженных центров глауконита в результате ионного обмена с внекаркасными катионами и образование ассоциатов. Сорбция пиридоксина по механизму ионного обмена с максимальной вероятностью описывает модель Ленгмюра.

Authors: Рагимли Манзар Ахмед кызы , Нуриев Али Наджафгулу оглы
Published: February 2018

Изучено влияние механической обработки сорбента Tермоксид-5 с содержанием 6.2 вес.% ZrO2 на сорбцию урана из моделирующих состав морской воды растворов. При использовании свежеизмельченных мелкодисперсных фракций обнаружен эффект неравновесной разупорядоченности кристаллической решетки сорбента в виде пиков на кинетических кривых, исчезающих по истечению определенного времени. Полученные результаты позволили рассчитать значения энергии активации и эффективные коэффициенты диффузии дефектов в Термоксиде-5 при различных температурах. Установлено, что появление характерных максимумов на кине­тических кривых связано с резким увеличением скоростей сорбции вследствие перестройки структуры сорбента в момент фазового перехода. Полученный эффект подтвержден данными рентгенофазового анализа. Интерпретация полученных результатов привела к выводу, что интенсивное измельчение сорбентов дестабилизирует их структуру и резко увеличивает скорость сорбции, а при стабилизации происходит полное восстановление сорбционных свойств.

Küreselleşme Karşıtı Yaklaşımların Felsefi Temelinin Yönetim Bilimleri Açısından İncelenmesi
Authors: Keskin Doç. Dr. Uğur
Published: February 2018

 Kuramsal çalışmalar incelendiğinde sadece küreselleşme literatürünün değil, her türlü kuramsal yaklaşımın çeşitli düşünsel soyutlamalar yoluyla tanınmak ve düzenlenmek istendiği görülmektedir. Örneğin ulus devletler topluluğu, sistem veya küreselleşme açısından çeşitli toplumsal, kurumsal veya yönetimsel soyutlamalar yapılmış, modeller geliştirilmiştir. Özellikle son yıllarda yönetimsel yapılanmalar (ulus-devlet) konusunda görüş farklılıklarına bağlı olarak küreselleşme eksenli çeşitli soyutlamalar yapılmıştır. Dolayısıyla, küreselleşmeye ilişkin yaklaşımlar, güncel ve indirgemeci bir tartışma olmanın çok ötesinde; gerek küreselleşme yanlısı, gerekse küreselleşme karşıtı yaklaşımlar açısından tarihsel olarak geriye doğru götürülerek felsefi temelleri açısından ele alınmayı gerektirecek bir nitelik arz etmesine karşın bu alanda yapılan kuramsal çalışmaların azlığı dikkat çekicidir. Bu çalışmada, küreselleşme karşıtı görüşler ağırlıkta olmasına karşın, tek yanlı vurgulama yapmaktan kaçınılarak bütüncül bir betimleme yapılmaya çalışılmış ve literatüre katkıda bulunmak amaçlanmıştır. 
Clinical profile and skin prick test analysis in children with allergic rhinitis of North Kerala, India
Authors: K. P. Shyna , M. Veena Kumari , K. Divya Krishnan , V. K. Abdul Azeez
Published: February 2018

Background: Allergic rhinitis (AR) is increasing in prevalence among children globally and in India. Allergens are factors which trigger allergic rhinitis. Skin prick test (SPT) is a rapid, sensitive and cost effective test to detect IgE- mediated allergic diseases. Identification of common aeroallergens in an area is necessary, in order to educate the patient on what allergens to avoid and also help find the best formulation of allergen immunotherapy for effective AR treatment. This study was done to find the clinical profile and skin sensitivity to common allergens by skin prick test in children with allergic rhinitis between six and fifteen years.Methods: This cross-sectional study was conducted for a period of one year from January 2016 to December 2016. All children between 6 to 15 years with allergic rhinitis were included in the study. Skin prick test was done with seven most common allergens.Results: A total of 60 children with allergic rhinitis were studied and 42 patients (70%) tested positive for SPT. The major symptoms were persistent sneezing (68%), nasal itching (33%), rhinorrhea (85%) and nasal congestion (42%). The proportion of sneezers-runners was higher than blockers (64% versus 36). We tested seven common allergens and house dust mite allergen yielded the highest number of positive responses (33%) followed by cockroach (25%), alternaria (16.66%), parthenium (10%), cat dander (8.35%), sorghum (5%) and dog dander (5%). Among patients with SPT positivity; eight were positive to one allergen, thirteen were positive to two allergens, sixteen to three allergens and five to four allergens.Conclusions: Allergic Rhinitis with a number of allergic co morbidities has a significant impact on the quality of life and scholastic performance in children. Skin prick test which is a standardized, most rapid, sensitive and cost-effective test to detect IgE-mediated allergic diseases is helpful in identifying the common allergens. House dust mite is the commonest allergen tested positive in our study in children.
The Roots and Dynamic of Radicalism among Students in Medan
Authors: Simanihuruk Muba , Zuska Fikarwin
Published: February 2018

This paper aims to explore intolerance or radicalism among students in the city of Medan. The phenomenon of radicalism of youth is an important phenomenon and attractive pattern of transnational, cross-cultural and cross-history. Moreover, radicalism is a sort of terrorism. Natana J. DeLong-Bas as quoted by Arza (2012) calls for driving a wave of youth such changes as the “Facebook generation” or “internet generation” because the massive and intensive use of social media in orchestration movement demanded a change. Tragically, during conducting this research, a high school student who has recently graduated attempted murder of a priest who preaches in Sint Yoseph Church in Medan. Police investigations revealed that the action of attempted murder is linked to an international terrorist network, ISIS. The sample of this study was high school students and university students in Medan including religious teachers with a total sample of 175 people (150 students and 25 teachers). As the samples are selected non-randomly, its conclusion does not represent the opinion of entire youth in Medan. The study reveals that there is no single explanation for the occurrence of radicalism among the youth. Although in general, it can be said that each religion (Islam, Catholicism, Protestantism, Hinduism, and Buddhism) is less accepting of other religions in neighborhood relations, political relations as well as in economic cooperation. In other words, young generation in Medan was also less tolerant primarily due to a clash of religious beliefs and experiences of discriminatory treatment by other religious groups.

Published: February 2018

This study is aimed to analyze the relationship between work-family conflict on career success orientation and career development. This study used 180 career women respondents in the governor’s office in East Nusa Tenggara Province, Indonesia. Qualitative and quantitative data from primary and secondary sources were collected by distributing questionnaires to the respondents. Purposive sampling was applied, and the data were analyzed using descriptive and inferential analysis of Partial Least Square. The result shows that work-family conflict does not significantly affect women’s’ career development but significantly affects the career success orientation. Also, career success orientation significantly affects woman’s career development. This study further reveals that career success is a strategic orientation as a mediation role between work-family conflict and woman’s career development. Based on the models, this study indicates that 50.06% (Q2-predictive relevance) in the variation of the career development can be explained by career success orientation and work-family conflict. Wo

Methods: A cross sectional study was conducted from March to April 2015 among people aged 50 years and over attending two Pension Fund departments and pregnant and nursing women attending Bè Hospital in Lome. Data were collected using a pre-tested face-to-face questionnaire. Participants were surveyed about their knowledge and consumption habits of soybean, Moringa oleifera, Aloe vera products and other agro-resources. Results: A total of 847 respondents were included in the study with 426 pregnant/nursing women and 421 people aged 50 years and over. The majority of respondents were married (39.5%) and 45.3% of the elderly people were widowed. At least nine over ten respondents (96%) knew soybean products and 76.8% of them reported a lifetime consumption of soybean products. The available and most consumed agro-resources included tofu (82.7%), moringa leaves (87.2%) and soy flour (29.7%). The least consumed products were soymilk, soy yogurt and moringa juice. Respondents also reported using moringa tea and soap, as well as Aloe vera juice and toothpaste. Conclusion: Soybean products and other agricultural resources are well known and consumed by people living in Lome. Data on actual food intake is useful to public health professionals and food safety risk assessors. It is important to inform the public at large of the recognized benefits of some foods that will provide solutions to their health problems.

Published: February 2018

Black plum, the fruit of Vitex doniana, was harvested in three (3) regions belonging to different climatic zones in northern Côte d'Ivoire. Biochemical characteristics of the pulps were studied in order to highlight their nutritional potential and the variability of this composition according to study areas. From the conventional biochemical analyzes used, it appears that the fruit pulp is acidic and mostly made up of water. It is rich in sugars and has antioxidant power between 18.63 ± 0.02 and 35.54 ± 0.01 µg.mL -1. There is also the presence of polyphenols (166.67 ± 0.01 – 196.67 ± 0.01 mEq A.G./100g) and vitamin C (14.34 ± 0.02 – 15.05 ± 0.07 mg/100g). Ashes consist of minerals such as magnesium, potassium and calcium. The analysis of the variance showed that the mean of the parameters studied are significantly different from one region to the other, except the ash rate and vitamin C content. In view of its nutritional quality, black plum presents itself as an interesting fruit to be taken into account in the prevention of certain dietary imbalances and which can even intervene at low cost in the treatment of certain pathologies.

Published: February 2018

Soil erosion causes many environmental and socio-economic problems: loss of biodiversity, decrease in the productivity of agricultural land, siltation of dams and increased risk of flooding. It is therefore essential to establish a detailed evaluation of this process before any spatial planning. To evaluate the effects of soil erosion spatially and quantitatively in order to face this phenomenon, and propose the best conservation and land development strategies, the Universal Soil Loss Equation (USLE) coupled with a geographic information system (GIS) is applied. This model is a multiplication of the five erosion factors: the erosivity of the rain, the erodibility of the soil, the inclination and the slope length, the vegetation cover and the anti-erosion practices. The study area is the Moulay Bouchta watershed (7 889 ha), which is located in the western part of the Rif Mountains, is characterized by a complex and contrasting landscape. The resulting soil loss map shows an average erosion rate of 39.5 (t/ha/yr), 87% of the basin has an erosion rate above the tolerance threshold for soil loss (7 (t/ha/yr)). Soil losses per subbasin range from 16.2 to 81.4 (t/ha/yr). The amount of eroded soil is estimated at 311,591 (t/yr), corresponding to a specific degradation of 12.1 (t/ha/yr). In the absence of any erosion control, 25% of the soil losses would reach the new dam located a little upstream of the basin outlet, reducing its water mobilization capacity to 59,625 (m3/yr). The application of Principal Component Analysis (PCA) to soil erosion factors shows a significant influence of topographic factor (LS) on soil erosion process, followed by the effect of support practices (P), then by soil erodibility (K).

The purpose of this paper is to develop and validate mathematical models of different elements or subsystems of our hybrid power generation system. Each component is modeled as a modular block that can easily be electrically connected to other subsystems. We used the software Matlab®- Simulink R2012a for implementation of our different models. The equations used here are empirical-semi empirical equations and allowed us to model our different components to describe correctly phenomena involved. It was necessary to have data from manufacturer such as polarization curve, surface of an elementary cell, coefficient related to threshold operating parameters, auxiliary consumption parameters and gas stoichiometry. All these allowed us to build under Matlab®-Simulink, photovoltaic panels block, battery pack block, fuel cell block, electrolyzer block and all curves representing different powers produced or consumed and different gases produced or consumed.

Information on morphological characteristics is a prerequisite to sustainable breed improvement, utilization, and conservation. In this study, 108 N’Dama cattle cows from 11 farms of central and northwestern regions of Côte d’Ivoire were described using visual appreciation criteria and linear body measurements. The variables were studied using principal component analysis (PCA) and discriminant analysis. Results indicated that the most common N’Dama is fauve (83.33%) and it has straight back profile (69.44%) and lyre horn (74.07%). Agroecological zone has a significant (p˂0.01) effect on linear body measurements of N’Dama. The central region animals had higher head width (18.94 ± 2.18 cm), skull length (22.51 ± 2.18 cm), skull width (16.51 ± 1.72 cm), muzzle circumference (40.83 ± 2.58 cm), distance between horns (15 ± 1.90 cm), ear length (17.46 ± 2.57 cm), chest length (160.11 ± 15.8 cm), chest depth (71.55 ± 7.41 cm), and body length (125.13 ± 12.22cm) than those of northwestern region N’Dama. Thus, their respective values were: 15.41 ± 2.85 cm, 18.62 ± 2.6 cm, 12.44 ± 3.94 cm, 38.8 ± 2.61 cm, 13.72 ± 1.52 cm, 16.41 ± 1.61 cm, 143.84 ± 8.35 cm, 65.25 ± 4.1 cm, and 119.18 ± 12.38 cm. PCA revealed that N’Dama morphometric variability performed from the 9 variables (Lt, lt, Lc, lc, pt, hg, Pth, Lcp and Lf) were more associated with the first two factors. In regards to the discriminant analysis, these 9 variables distinguished the N’Dama significantly (p˂0.05) into two populations that corresponds with the two agroecological zones.

2-D CVES surveys using the Wenner configuration was carried out in 22 communities in the Tain District, Ghana. This was done with the objectives of assessing the subsurface geology, identify high groundwater potential zones for drilling high-yielding boreholes that could yield sustainable amount of groundwater. The collected resistivity data were converted from the apparent resistivity to 2-D modelsection using the least-square inversion algorithm with the help of Res2DInv software. The 2-D resistivity model-sections produced a high quality structural resolution leading to the demarcation of the layering of various lithological units, weathered layers and identification of important structures such as joints, fractures and faults. Quantitatively, it can be observed that all the drilled wet wells have aquifer zones between 30 m and 60 m within sandstone, siltstone and phyllite granitic environments. The result of the borehole drill logs revealed that the aquifers were within weathered and fractured zones and is in agreement with the models. The results showed that the boreholes yield within the study area varied between a minimum of 15 litres/min to a maximum 800 litres/min and the mean depth for intercepting aquifer was at about 30 m and below. The study revealed that the potential aquifer zones in the study area are mostly as a result of weathering of the overburden and fracturing of the underlying bedrock. The results suggest that the hydrogeology of the study area is highly complex since the development of groundwater is generally due to secondary porosities.

The effect of black and green

tea on viscosity and sensory characteristics of drinking yoghurt was

investigated. Two tea infusion concentrations (2% and 4%) were used in the

study whereas drinking yoghurt without any additive was the control sample. The

highest viscosity values were determined in control sample while there were no

significant differences among the drinking yoghurts supplemented with tea

extracts except 14th day. Addition of tea at a ratio of 4% adversely

affected the taste scores when compared to the ratio of 2%. Drinking yoghurt

infused by 2% green tea had similar colour and texture values to that of

control sample. There were no statistically differences between samples

supplemented with 2% either black or green tea in terms of

overall acceptability.

Let's Find Momo by A. Knapp
Authors: Kung Janice
Published: February 2018

Knapp, Andrew. Let’s Find Momo. Quirk Books, 2017.This hide-and-seek board book is the latest from photographer, Andrew Knapp and his extremely photogenic border collie named Momo. The black and white border collie loves hiding and invites young readers to find itself and other objects. Left-hand pages list three different objects and Momo who are hidden in the corresponding right pages. Each page explores different environments along with objects that are typically found therein, but not always. For instance, in the library, readers are tasked to find a lollipop, a banana, a balloon, and Momo.Similar to Where’s Waldo, this picture book allows readers to find objects and the cute little dog that does his very best at staying hidden. The border collie takes readers on many adventures such as to a merry-go-round, gymnasium, garden, bedroom, and even a farm. With themes carefully selected, they provide a wide range of new words for young readers to learn. Each location is beautifully photographed with vibrant colours and unique angles while, at the same time, teaches new vocabulary to young children, aged 2-4.  Highly Recommended: 4 out of 4 starsReviewer: Janice KungJanice Kung is a Public Services Librarian at the University of Alberta, John W.

Rez Rebel by M. Florence
Authors: Quaiattini Andrea
Published: February 2018

Florence, Melanie. Rez Rebel. James Lorimer & Company, 2017.Narrated by Floyd Twofeathers, a young Cree teenager living on the fictional Bitter Lake Reserve, Rez Rebel sheds important and much-needed light onto the suicide crisis faced by Indigenous communities across Canada.Suicides on Bitter Lake Reserve are rampant. Though Floyd occupies a position of status in his community, with his father being the hereditary chief and his mother a traditional healer, he is not immune from the tragedy—his best friend Aaron had committed suicide. However, after a suicide pact leaves four young girls dead, Floyd’s father struggles to find a solution to help his community and its young people find opportunities and support. Floyd and his friends believe that by sharing their own talents and skills (writing, drawing, sports) with their peers, and giving kids the opportunity to learn their traditional knowledge and practices from the Elders, that this will help turn their community around. When Floyd tries to bring these ideas to his father, he is ignored. It is only with a bold act, and another suicide threat that brings about meaningful change on Bitter Lake Reserve.Given the timeliness of the subject matter, and the lack of books on this topic, this is a much-needed novel. However, the overall story itself is a bit uneven. The book opens with the suicide crisis, and the reader can feel the tension and urgency of the situation. There is a lengthy description of Aaron’s suicide, as well as a crisis in Floyd’s family that may be upsetting or triggering to some readers. The middle of the book loses a bit of its focus, with chapters showing Floyd and his friends being teenagers—hanging out, fishing, falling in love—with little connection to the broader plot. The final quarter of the story reconnects the reader with the suicide crisis and Floyd’s solution for his community. The prose and tone are realistic—teenagers will see themselves in the characters, and the language is simple and accessible.This book would do well in the young adult section of public libraries, as well as in junior high and high school libraries. Recommended: 3 out of 4 starsReviewer: Andrea QuaiattiniAndrea Quaiattini is a Public Services Librarian at the University of Alberta’s JW Scott Health Sciences Library.  While working as a camp counsellor, she memorized Mortimer and The Paper Bag Princess by Robert Munsch as bedtime stories for the kids.

O mito de Tuku Pararã í: Explicando a Agressividade Territorial e Ambiental dos “Brancos” (Juruá) e a Ontologia da Paisagem Atual
Authors: Mega Orestes Jayme
Published: February 2018

A proposta deste artigo é a de mostrar a relação existente entre aspectos ambientais da paisagem e aspectos da mitologia Mbyá-Guarani. A pesquisa foi realizada na aldeia Mbyá-Guarani denominada Tekoá Tavaí, localizada no município de Cristal, estado do Rio Grande do Sul. Na pesquisa foi utilizada uma abordagem teórica baseada nas ideias do arqueólogo norte-americano Severin Fowles, que caracteriza a arqueologia como a ciência das “grandes narrativas” (ALBERTI et al, 2011). Como resultado da pesquisa, foi verificado que os Mbyá-Guarani que residem na Tekoá Tavaí entendem as mudanças nas condições ambientais da paisagem em que vivem através da agência de entidades espirituais relacionadas à mitologia Mbyá-Guarani.
Educação Patrimonial no Campo da Arqueologia: desafios e contribuições
Authors: Baima Carlúcio , Biondo Fernanda , Nito Mariana Kimie
Published: February 2018

Este artigo abrangerá questões referentes a preservação do patrimônio cultural tendo como foco o papel da Educação Patrimonial nos trabalhos arqueológicos tratados durante o Mini Curso ministrados pelos autores na Segunda Semana de Arqueologia da UNICAMP. Apesar das exigências de Educação Patrimonial em licenciamentos ambientais, com pesquisas cada vez mais crescentes, não há diretrizes ou especificações que orientem estas ações, que podem ser elaboradas de formas variadas. Na atual conjuntura, vemos que a Educação Patrimonial não deve se limitar a atividades pontuais ou promocionais aos empreendimentos, mas, sobretudo, fomentar a construção coletiva do conhecimento e a autonomia dos sujeitos. Assim, neste artigo iremos elaborar uma análise sobre os desafios da Educação Patrimonial nas ações de licenciamento arqueológico, contribuindo para novas práticas educativas encaradas como ações político-sociais. E como tais assuntos foram tratados durante o Mini Curso.

Ânforas, commodities agrícolas e o ocaso do minimalismo econômico
Authors: Duprat Paulo Pires
Published: February 2018

A utilização de ânforas como método de acondicionamento foi praticada por todos os povos mediterrânicos, destacando um aspecto tecnológico comum que pode ser comprovado pela Arqueologia sob extenso recorte temporal e geográfico. Novos estudos sobre ânforas gregas e romanas estão condenando ao ocaso a visão minimalista para a economia antiga e sua noção de que apenas bens de luxo eram comercializados, haja visto que a utilização de ânforas está associada ao transporte de “commodities agrícolas”. Vou apresentar algumas perspectivas oriundas do marketing design que consideram as ânforas como as primeiras embalagens de consumo (consumer package) fabricadas em larga escala, cujo projeto e design demonstram que os povos antigos praticavam uma variante de racionalismo econômico que só pode ser apreendida se analisada em seu próprio contexto.

Uma ruína, duas histórias: uma breve análise sobre a pequena ruína da TekoáTavaí
Authors: Mega Orestes Jaime
Published: February 2018

A partir dos dados etnográficos obtidos na aldeia Mbyá-Guarani chamada TekoáTavaí, localizada no município de Cristal, estado do Rio Grande do Sul, realizou- se uma análise a respeito da convivência e sobreposição de historicidades distintas intermediadas por um elemento da paisagem que serve como “símbolo material” para doisgrupos que dividem a paisagem em questão: a brasileira, e a Mbyá-Guarani. Este “símbolo material” se constitui de uma ruína de uma casa que é interpretada de diferentes maneiras a depender da perspectiva cultural. A proposta deste artigo é a de mostrar que um “símbolo material” inserido na paisagem assume tanto um caráter cívico, ligado a eventos históricos, quanto um caráter religioso relacionado a eventos míticos e, assim, pode ser integrado a duas formas diferentes de estruturas de entendimento histórico.
Diálogos entre Paisagens e Arqueologia (s): questões e possibilidades
Authors: Póvoa Maria Bernadete
Published: February 2018

Este artigo apresenta os dados de dois abrigos rupestres popularmente denominados como “Os abrigos do Cera “, localizados na Serra de Aquidauna, sudoeste do Estado de Mato grosso do Sul. Trata-se da primeira escavação sistemática nesta área de pesquisa. A datação pelo método de Temoluminescência de um dos fragmentos cerâmicos do abrigo Aquidauna IV a :   foi de 690+ ou 80 BP. A pesquisa faz uma detalhada arqueografia das evidências arqueológicas presentes nos abrigos e aponta os primeiros elementos que os configurem na paisagem. Dessa forma pretendemos apontar que sua inserção na paisagem pode ser diagnosticada dentro de escolhas e representações simbólicas presentes nos abrigos sob rocha, como partes constitutivas da construção social integrada na paisagem, consolidando-se na cultura material. Dessa forma pretendemos ampliar nossa percepção dentro de questões e possibilidades estabelecendo “Diálogos entre paisagens e Arqueologia (s)”.

Published: February 2018

Neste artigo refletimos criticamente sobre o desenvolvimento das investigações arqueológicas interessadas nas ditaduras militares na América do Sul. Para isso, centramos a atenção no caso argentino, tendo em vista sua história de políticas repressivas extremas; seu caráter pioneiro, abundante e diverso dos estudos sobre a temática, e a nossa própria experiência de trabalho, que possui cerca de 10 anos de duração. Inicialmente, discutimos a orientação que caracterizou os estudos, assim como os fatores sociais, políticos e acadêmicos que os impactaram. Posteriormente, apresentamos alguns desafios que o recorte tem apresentado, e ainda apresenta, aos investigadores.
