Authors: Henriksen André , Haugen Mikalsen Martin , Woldaregay Ashenafi Zebene , Muzny Miroslav , Hartvigsen Gunnar , Hopstock Laila Arnesdatter , Grimsgaard Sameline
Published: November 2017

BACKGROUND

New fitness trackers and smartwatches are released to the consumer market every year. These devices are equipped with different sensors, algorithms, and accompanying mobile apps. With recent advances in mobile sensor technology, privately collected physical activity data can be used as an addition to existing methods for health data collection in research. Furthermore, data collected from these devices have possible applications in patient diagnostics and treatment. With an increasing number of diverse brands, there is a need for an overview of device sensor support, as well as device applicability in research projects.

OBJECTIVE

The objective of this study was to examine the availability of wrist-worn fitness wearables and analyze availability of relevant fitness sensors from 2011 to 2017. Furthermore, the study was designed to assess brand usage in research projects, compare common brands in terms of developer access to collected health data, and features to consider when deciding which brand to use in future research.

METHODS

We searched for devices and brand names in six wearable device databases. For each brand, we identified additional devices on official brand websites. The search was limited to wrist-worn fitness wearables with accelerometers, for which we mapped brand, release year, and supported sensors relevant for fitness tracking. In addition, we conducted a Medical Literature Analysis and Retrieval System Online (MEDLINE) and ClinicalTrials search to determine brand usage in research projects. Finally, we investigated developer accessibility to the health data collected by identified brands.

RESULTS

We identified 423 unique devices from 132 different brands. Forty-seven percent of brands released only one device. Introduction of new brands peaked in 2014, and the highest number of new devices was introduced in 2015. Sensor support increased every year, and in addition to the accelerometer, a photoplethysmograph, for estimating heart rate, was the most common sensor. Out of the brands currently available, the five most often used in research projects are Fitbit, Garmin, Misfit, Apple, and Polar. Fitbit is used in twice as many validation studies as any other brands and is registered in ClinicalTrials studies 10 times as often as other brands.

CONCLUSIONS

The wearable landscape is in constant change. New devices and brands are released every year, promising improved measurements and user experience. At the same time, other brands disappear from the consumer market for various reasons. Advances in device quality offer new opportunities for research. However, only a few well-established brands are frequently used in research projects, and even less are thoroughly validated.

Published: November 2017

BACKGROUND

Despite the growing number of mental health apps available for smartphones, the perceived usability of these apps from the perspectives of end users or health care experts has rarely been reported. This information is vital, particularly for self-guided mHealth interventions, as perceptions of navigability and quality of content are likely to impact participant engagement and treatment compliance.

OBJECTIVE

The aim of this study was to conduct a usability evaluation of a personalized, self-guided, app-based intervention for depression.

METHODS

Participants were administered the System Usability Scale and open-ended questions as part of a semistructured interview. There were 15 participants equally divided into 3 groups: (1) individuals with clinical depression who were the target audience for the app, (2) mental health professionals, and (3) researchers who specialize in the area of eHealth interventions and/or depression research.

RESULTS

The end-user group rated the app highly, both in quantitative and qualitative assessments. The 2 expert groups highlighted the self-monitoring features and range of established psychological treatment options (such as behavioral activation and cognitive restructuring) but had concerns that the amount and layout of content may be difficult for end users to navigate in a self-directed fashion. The end-user data did not confirm these concerns.

CONCLUSIONS

Encouraging participant engagement via self-monitoring and feedback, as well as personalized messaging, may be a viable way to maintain participation in self-guided interventions. Further evaluation is necessary to determine whether levels of engagement with these features enhance treatment effects.
Oncosurgical Management of Liver Limited Stage IV Colorectal Cancer: Preliminary Data and Protocol for a Randomized Controlled Trial (Preprint)
Authors: Sutton Paul , Vimalachandran Dale , Poston Graeme , Fenwick Stephen , Malik Hassan
Published: November 2017

BACKGROUND

Colorectal cancer is the fourth commonest cancer and second commonest cause of cancer-related death in the United Kingdom. Almost 15% of patients have metastases on presentation. An increasing number of surgical strategies and better neoadjuvant treatment options are responsible for more patients undergoing resection of liver metastases, with prolonged survival in a select group of patients who present with synchronous disease. It is clear that the optimal strategy for the management of these patients remains unclear, and there is certainly a complete absence of Level 1 evidence in the literature.

OBJECTIVE

The objective of this study is to undertake preliminary work and devise an outline trial protocol to inform the future development of clinical studies to investigate the management of patients with liver limited stage IV colorectal cancer.

METHODS

We have undertaken some preliminary work and begun the process of designing a randomized controlled trial and present a draft trial protocol here.

RESULTS

This study is at the protocol development stage only, and as such no results are available. There is no funding in place for this study, and no anticipated start date.

CONCLUSIONS

We have presented preliminary work and an outline trial protocol which we anticipate will inform the future development of clinical studies to investigate the management of patients with liver limited stage IV colorectal cancer. We do not believe that the trial we have designed will answer the most significant clinical questions, nor that it is feasible to be delivered within the United Kingdom’s National Health Service at this current time.

Semi-device-independent framework based on natural physical assumptions
Authors: Van Himbeeck Thomas , Woodhead Erik , Cerf Nicolas J. , García-Patrón Raúl , Pironio Stefano
Published: November 2017

The semi-device-independent approach provides a framework for prepare-and-measure quantum protocols using devices whose behavior must not be characterized nor trusted, except for a single assumption on the dimension of the Hilbert space characterizing the quantum carriers. Here, we propose instead to constrain the quantum carriers through a bound on the mean value of a well-chosen observable. This modified assumption is physically better motivated than a dimension bound and closer to the description of actual experiments. In particular, we consider quantum optical schemes where the source emits quantum states described in an infinite-dimensional Fock space and model our assumption as an upper bound on the average photon number in the emitted states. We characterize the set of correlations that may be exhibited in the simplest possible scenario compatible with our new framework, based on two energy-constrained state preparations and a two-outcome measurement. Interestingly, we uncover the existence of quantum correlations exceeding the set of classical correlations that can be produced by devices behaving in a purely pre-determined fashion (possibly including shared randomness). This feature suggests immediate applications to certified randomness generation. Along this line, we analyze the achievable correlations in several prepare-and-measure optical schemes with a mean photon number constraint and demonstrate that they allow for the generation of certified randomness. Our simplest optical scheme works by the on-off keying of an attenuated laser source followed by photocounting. It opens the path to more sophisticated energy-constrained semi-device-independent quantum cryptography protocols, such as quantum key distribution.

Ectopic Pregnancy Following Interval Tubal Sterilization
Authors: Shrestha Deepak , Baniya Sebina , Regmi Sudeep
Published: November 2017

Introduction:  Tubal sterilization is a highly effective method of permanent contraception. However, pregnancy can still occur following a successful procedure. Published literatures report a failure rate of 0.13-1.3% and 15-33% of such pregnancies are likely to be ectopic.

Case report: A 33 years para three lady with prior history of tubal ligation presented with generalized abdominal pain and several episodes of vomiting. Bimanual examination revealed a soft and mobile mass of 2 x 3 cm in right adnexa. Urine pregnancy test was positive and ultrasonogram showed a heterogeneous mass of 3.4 x 3.3 cm in right adnexa with empty uterine cavity. Culdocentesis resulted in aspiration of frank non-clotting blood. She then underwent emergency laparotomy with bilateral salpingectomy for ruptured ectopic pregnancy.

Conclusion: Ectopic pregnancy after tubal sterilization though rare is not entirely impossible. All women who are offered this procedure should always be educated about its failure rate. And in women presenting with acute abdomen, a prior history of tubal sterilization doesn't preclude the possibility of ectopic pregnancy.
Impact of the 2013 National Rollout of CMS Competitive Bidding Program: The Disruption Continues
Authors: Puckrein Gary A. , Hirsch Irl B. , Parkin Christopher G. , Taylor Bruce T. , Xu Liou , Marrero David G.
Published: November 2017

OBJECTIVE

Use of glucose monitoring is essential to the safety of individuals with insulin-treated diabetes. In 2011, the Centers for Medicare & Medicaid Services (CMS) implemented the Medicare Competitive Bidding Program (CBP) in nine test markets. This resulted in a substantial disruption of beneficiary access to self-monitoring of blood glucose (SMBG) supplies and significant increases in the percentage of beneficiaries with either reduced or no acquisition of supplies. These reductions were significantly associated with increased mortality, hospitalizations, and costs. The CBP was implemented nationally in July 2013. We evaluated the impact of this rollout to determine if the adverse outcomes seen in 2011 persisted.

RESEARCH DESIGN AND METHODS

This longitudinal study followed 529,627 insulin-treated beneficiaries from 2009 through 2013 to assess changes in beneficiary acquisition of testing supplies in the initial nine test markets (TEST, n = 43,939) and beneficiaries not affected by the 2011 rollout (NONTEST, n = 485,688). All Medicare beneficiary records for analysis were obtained from CMS.

RESULTS

The percentages of beneficiaries with partial/no SMBG acquisition were significantly higher in both the TEST (37.4%) and NONTEST (37.6%) groups after the first 6 months of the national CBP rollout, showing increases of 48.1% and 60.0%, respectively (both P < 0.0001). The percentage of beneficiaries with no record for SMBG acquisition increased from 54.1% in January 2013 to 62.5% by December 2013.

CONCLUSIONS

Disruption of beneficiary access to their prescribed SMBG supplies has persisted and worsened. Diabetes testing supplies should be excluded from the CBP until transparent, science-based methodologies for safety monitoring are adopted and implemented.
Declining Rates of Hospitalization for Selected Cardiovascular Disease Conditions Among Adults Aged ≥35 Years With Diagnosed Diabetes, U.S., 1998–2014
Authors: Burrows Nilka Ríos , Li YanFeng , Gregg Edward W. , Geiss Linda S.
Published: November 2017

OBJECTIVE

Reductions in heart attack and stroke hospitalizations are well documented in the U.S. population with diabetes. We extended trend analyses to other cardiovascular disease (CVD) conditions, including stroke by type, and used four additional years of data.

RESEARCH DESIGN AND METHODS

Using 1998–2014 National (Nationwide) Inpatient Sample (NIS) data, we estimated the number of discharges having acute coronary syndrome (ACS) (ICD-9 codes 410–411), cardiac dysrhythmia (427), heart failure (428), hemorrhagic stroke (430–432), or ischemic stroke (433.x1, 434, and 436) as first-listed diagnosis and diabetes (250) as secondary diagnosis. Hospitalization rates for adults aged ≥35 years were calculated using estimates from the population with and the population without diabetes from the National Health Interview Survey (NHIS) and age-adjusted to the 2000 U.S. standard population. Joinpoint regression was used to analyze trends and calculate an average annual percentage change (AAPC) with 95% confidence limits (CLs).

RESULTS

From 1998 to 2014, in the population with diabetes, age-adjusted hospitalization rates declined significantly for ACS (AAPC −4.6% per year [95% CL −5.3, −3.8]), cardiac dysrhythmia (−0.7% [−1.1, −0.2]), heart failure (−3.6% [−4.6, −2.7]), hemorrhagic stroke (−1.1% [−1.4, −0.7]), and ischemic stroke (−2.9% [−3.9, −1.8]). In the population without diabetes, rates also declined significantly for these conditions, with the exception of dysrhythmia. By 2014, rates in the population with diabetes population remained two to four times as high as those for the population without diabetes, with the largest difference in heart failure rates.

CONCLUSIONS

CVD hospitalization rates declined significantly in both the population with diabetes and the population without diabetes. This may be due to several factors, including new or more aggressive treatments and reductions in CVD risk factors and CVD incidence.
The Effect of Sunspot Cycles on the Precipitation Over Iraq
Authors: Hassan Baidaa J.
Published: November 2017

Continuous wavelet transformation (C.W.T) by MATLAB technique has been used to study the relations between the sunspot cycles (solar activity) with annual precipitation over Iraq (for about 10 cycles). Results indicated that the sunspot numbers have three main periods, around 11, 21 and 33 years, while the precipitation has the same periods in addition to a small period (3-7years). By applying moving average according to the periodicities that found by continuous wavelet transformation, relations between solar cycles were closely related to the annual precipitation over Iraq.

Authors: Ahmed Sahar M.
Published: November 2017

In the last few decades there has been an exponential growth in the field of herbal medicine. One

such medicinal plant is Ricinus communis (Euphorbiaceae), which is commonly known as castor.

All parts of the plant are important phloem, bark, leaves, flowers, seed and oil. The study was

conducted on 15 mature rabbitsof either sex of 1-2 kg body weight and 1-2 years old. The animals

were divided into three groups of 5 animals each. Animals of group I were exposed orally to ricin

extract at a dose rate of 0.5 mg /kg b.wt. daily for 14 days, while those of group II were exposed

orally to aqueous leaves extract 0.5mg /kg b.wt daily for 14 day, mean while those of group III

were left as a control group not exposed. The dependent parameters in the study were hemoglobin

(Hb) concentration, total erythrocytes count, packed cells volume (PCV%), erythrocytes indices

mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular

hemoglobin concentration (MCHC), Total and differential leucocytes count (TLC and DLC), in

addition to some biochemical tests of blood serum which obtained at day 14th post exposure. The

results of the study were revealed that the ricin extract and leaf extract exhibited an effects on

hematological pictures as the erythrocytes counts, erythrocytes indices, Hb concentration and

PCV% decreased and the obvious effects were in the 14th day. Ricin extract was less effects on

many dependent parameters in comparison with aqueous leaf extract. Total leucocytes count,

neutrophils % was increased in both ricin and leaf extract, and the increasing were higher in the

7th day in Ricin extract group. The lymphocytes% was decreased. While monocytes, eosinophils, and basophils % did not show any significant changes in all groups. Neutrophil /lymphocyte (N/l), and monocyte /lymphocyte (M/l) increased in both exposed groups. Cholesterol (Chol), Triglyceride (TG)were increased, while total protein (TP)was decreased, Albumin (Alb), Cortisol (Cort), Total serum bilirubin (TSB) and Alanine aminotransferase (ALT)did not changed. Aspartate aminotransferase (AST) value was increased, while Adenosine phosphatase (AP) value was deceased. In conclusion castor oil due to its content of ricin exhibit an effects on hematological and biochemical parameters that depended in the study, and the leaves extract was higher than seed extract in its effects.

Published: November 2017

The study was conducted for estimating antifungal activity against Candida albicans of ten essential oil, garlic and onion juice, eight disinfectants and detergents by using agar diffusion well method. The results showed high activity of clove oil, onion juice 50%, thyme oil, hydrogen peroxide (H2O2), lugol's iodine and detol for all the five concentration, sodium chloride (NaCl) and sodium carbonate (Na2CO3) at 5%, while the effect of apple cider vinegar were at 60% and 80%. Sodium hypochlorite showed moderate activity at all concentration. The result of combination between clove oil and coconut oil led to synergistic effect while the combination between each of (1, 2, 3 % H2O2 with each of apple cider vinegar and NaCl), (sodium chloride with apple cider vinegar) and (pumpkin oil with clove oil) lead to antagonism as well as the same results were reported when apple cider vinegar mixed with each of (thyme oil) and (clove oil with coconut oil). On the other hand, there is no synergistic or antagonistic effect of combination between 4-5% of H2O2 with apple cider vinegar and NaCl solution to the growth of C. albicans. It was concluded that solitary use of compounds (clove oil, onion juice, thyme oil, H2O2, NaCl, lugol's iodine, detol, and apple cider vinegar) was associated with high antifungal response regarding C. albicans; efficacy was reduced when used in combination. In exception to above finding synergistic effect was identified when a combination between clove oil and coconut oil.

Authors: Al-Ubadi Alia E.
Published: November 2017

Association between Procalcitonin (PCT) and C-reactive protein (CRP) and burn injury was evaluated in 80 burned patients from Al-Kindy and Imam Ali hospitals in Baghdad-Iraq. Patients were divided into two groups, survivor group 56 (70%) and non-survivor group 24 (30%). PCT was estimated using (Human Procalcitonin ELISA kit) provided by RayBio/USA while CRP was performed using a latex agglutination kit from Chromatest (Spain).

Our results declared that the mean of Total Body Surface Area (TBSA %) affected were 63.5% range (36%–95%) in non-survivor patients, while 26.5% range (10%–70%) in survivor patients. There is a significant difference between the two groups (P = 0.00), the higher mean percentage of TBSA has a significant association with mortality.

Serum PCT and CRP were measured at the three times of sampling (within the first 48hr following admission, after 5thdays and after 10th days). The mean of PCT serum concentrations in non-survivor group (2638 ± 3013pg/ml) were higher than that of survivor group (588 ± 364pg/ml). Significantly high levels of CRP were found between the survivor and non-survivor groups especially in the 10th day of admission P=0.000, present study show that significant differences is found within the non-survivor group through the three times P= 0.01, while results were near to significant differences within survivor group through the three times (P= 0.05).

Authors: Hussein Asma I. , Hassan Nidaa F.
Published: November 2017

Blood cells are composed of erythrocytes (Red Blood Cells (RBCs)), the shape of RBC changes when the body suffers from different diseases such as Anemia. Classification of such diseases helps the medical technician to decide the type of Anemia in Laboratory analyzes in the hospitals. This paper proposed an automatic classification algorithm, which discriminates the different types of Anemia using Principal Component Analysis (PCA) algorithm and Decision tree. The proposed algorithm consists of four steps, at the first step preprocessing steps are applied on the RBC image, these RBC images then segmented in the second step, features are extracted using moment invariant in third step, this features are considered input to PCA so as to produced features vectors, at a final step features vector are inputted to Decision Tree to classify RBC image. Best classifications rates are (92%) obtained when using PCA algorithm compared with (74.1 %) which are obtained without applying PCA algorithm.

These films were characterized using UV/VIS spectrophotometer technique in order to estimate the type of electric transition which was found to be indirect transition. The value of the optical energy gap was decreased with increasing doping ratios of methyl green dye. Absorption coefficient, extinction coefficient, refractive index and energy gap have been also investigated; it was found that all the above parameters affects by doping dye.

The applications of polymer nanocomposites have been increased in fast, in technological applications and engineering materials for seal and sliding components in many machines, devices, tools and variance vehicles. In this research friction and wear coefficients of epoxy reinforced by nanoparticles silicon carbide in terms of variance volume fractions have been tested. Mechanical – layup method with ultrasonic technique for the dispersion of the nanoparticles within the polymer matrix are used. Wear and friction coefficient tests are created out using pin -on-disc technique. The results showed significant improvement in wear resistance and low coefficient of friction for 10 vol. % nanocomposites compared with the matrix alone. It can be concluded from scanning electron microscopy (SEM) results before and after the tests that the wear was transformed from the severe to the moderate.

La capacidad de coordinación mano-ojo con visión indirecta (CMOVI) es imprescindible en la práctica odontológica, pues de ella depende el acceso visual para maniobrar en regiones recónditas de la boca sin comprometer los principios ergonómicos. El objetivo de esta investigación es establecer si los dispositivos DIVIN y TrazaCav son útiles para identificar esa coordinación en aspirantes a ingresar al programa de Médico Cirujano Dentista (MCD) de la Unidad Académica de Odontología de la UAZ (UAO/UAZ). Para ello se realizó un estudio transversal experimental en una muestra aleatoria estratificada (n=169) de aspirantes a la UAO/UAZ, promociones 2014 a 2016. Cada sujeto ejecutó tres ejercicios de CMOVI, empleando el DIVIN y el TrazaCav, considerando tres categorías: precisión en el perfilado, profundidad en el trazado y tiempo empleado, evaluados por tres expertos. Los resultados, concentrados en cédula de registro, se sometieron a descripción de frecuencias y medidas de tendencia central. Los resultados fueron: 19 estudiantes ubicados en promedio general de 6.0 (sobre una base de 10), 16 en 5.3, 15 en 5.7 y 14 en 7.0, el resto se distribuye sin un patrón uniforme en las posibilidades restantes. En precisión en perfilado, 34 obtuvieron 1.7 de calificación (sobre una base de 4.0), 32 con 2.0 y 24 con 2.3. En profundidad en trazado, 31 se ubican en 2.3 de calificación (sobre una base de 4.0), 27 en 2.7 y 25 en 2.0. En tiempo empleado, 116 se agrupan en 2.0 de calificación (sobre una base de 2.0), 28 en 1.0 y 10 en 1.7. Las calificaciones son similares en cada edición, encontrándose mayor diferencia en 2015, con un ligero incremento en las de precisión y profundidad. En conclusión, se evidencia la utilidad del DIVIN y TrazaCav para identificar la CMOVI en aspirantes a MCD, dadas las constantes encontradas en cada una de las ediciones del curso propedéutico de esta institución.
The Unwanted Metonymy of the 1804 Usman Dan Fodio’s Jihad to the Contemporary Nigerian State
Authors: Uchenna Ebony Amanambu
Published: November 2017

This paper analyzes the eruption of some covert religio-political militant movements modeled after the 1804 Usman dan Fodio’s jihad who are engrossed with the penchant desire for launching jihads in Nigeria. It discusses also the Maitatsine’s imbroglio, Izala, the Shiites, the sharia propagandists between 1978 and 1999, Boko Haram’s insurgence and Fulani herdsmen onslaughts. It highlights the dangers of these disguised movements to the Nigerian socio political and economic existence and suggests some ways of checkmating their excesses.
Shakespeare’s Othello: The Esteemed, Reviled, Shunned, and Integrated?
Authors: D. Harris Dr Rachelle
Published: November 2017

In Shakespearean literature, one can find themes that challenge the Elizabethan conventional way of thinking and life, and the tragedy of Othello is no exception. In a dramatic presentation, Shakespeare challenges the way in which Black people are seen in Elizabethan society by placing a Moor in the context of Venice, Italy who is both hated and respected in his place in a racist society. There is no doubt that there is racism in Elizabethan society. According to Eldred Jones, during the era in which Othello is composed, Queen Elizabeth enacts legislation that calls for all Black people to leave the country (Jones, 1994). Racism is not the core theme of the dramatic piece; however, the existence of racism is illustrated and expressed via Shakespeare’s artistic medium. Just as feminism, greed, jealousy, hubris, and varying other matters dealing with the human spirit do not seepage Shakespeare’s consideration, nor do race matters. Furthermore, just as he dramatizes human issues, he dramatizes race matters. There are fictional elements in Othello that are intertwined with nonfictional matters of human behavior and racial unrest. In the middle of racial unrest, Shakespeare composes a theatrical production with a Black character who is esteemed, reviled, shunned, and integrated into such a society, capturing the complicated nature of communal racism itself.

Análises cerâmicas na arqueologia amazônica
Authors: Lima Helena Pinto
Published: November 2017

Classificação das cerâmicas arqueológicas foi tema bastante debatido entre arqueólogos que trabalharam na Amazônia nas décadas de 1950-70 e evidenciou divergências entre as hipóteses de ocupação da região. As diferentes interpretações dadas a este vestígio partiam de parâmetros classificatórios distintos. Este artigo apresenta as discussões sobre métodos de tratamento da cerâmica arqueológica na Amazônia, contextualizando as abordagens histórica e teoricamente. Num segundo momento expõe a metodologia de análise cerâmica utilizada para interpretar as sequências crono-estratigráficas dos contextos arqueológicos da Amazônia central e adjacências. Para tal, lança mão da análise e tipologia produzidas para o sítio arqueológico Jacuruxi, município de Manacapuru/AM, que desafiam os parâmetros interpretativos adotados e apontam para a necessidade de uma abordagem contextual abrangente.

Published: November 2017

A construção de um pseudo-sítio arqueológico, ou sítio arqueológico controlado, foi realizada na Estação Ecológica da Universidade Federal de Minas Gerais com o objetivo de simular um sítio arqueológico natural. Tal criação será importante para o aprimoramento de estudos arqueológicos em Minas Gerais. Além dos métodos clássicos de pesquisas arqueológicas, métodos geofísicos serão testados no pseudo-sítio como norteadores em pesquisas do gênero no Brasil e em especial na Zona da Mata Mineira. O pseudo-sítioconsiste em uma cava de 9m2, circundada por uma faixa de 1m de largura, o que determina uma área de estudo de 25 m2. Foi criado um mapa contendo o entorno da cava e as posições das peças dispostas no seu interior. Dentre os artefatos estão fragmentos de vasos cerâmicos de diversas dimensões, ossadas de animais, vasos cerâmicos de diversos tamanhos e em posição espaçadas de forma irregular.
Etnoarqueologia, conservação arqueológica e a compreensão dos processos de formação do registro arqueológico na Amazônia
Authors: Silva Fabíola Andréa , Lima Silvia Cunha
Published: November 2017

O registro arqueológico consiste de vestígios materiais que foram produzidos e alterados a partir de diferentes fatores culturais e naturais que são chamados de processos de formação. Neste trabalho – a partir da análise de vasilhas cerâmicas arqueológicas dos Asurini do Xingu – pretendemos mostrar que a associação entre a etnoarqueologia e a conservação arqueológica ampliam as possibilidades dos arqueólogos de compreender esses processos de formação do registro arqueológico. Analisaremos os artefatos cerâmicos, procurando verificar em que medida as suas características físicas revelam as alterações provocadas pelo uso e pelos processos pós-deposicionais de biodegradação.
Caracterização do sistema tecnológico da subcoleção laming-emperaire do lítico xetá depositada no MAE-UFPR

Published: November 2017

O Setor de Antropologia da Universidade Federal do Paraná enviou expedições de pesquisa entre 1956 e 1961 para a região onde foram identificados acampamentos Xetás, coletando informações sobre a cultura material deste grupo. Nestas expedições foram coletados 160 artefatos polidos e lascados que compõem a coleção de lítico Xetá depositada no MAE-UFPR. A partir de informações de contexto deste material, optou-se em dividi-lo em duas subcoleções para fins analíticos e comparativos: os artefatos coletados por Loureiro (sem dados de proveniência) e por Laming-Emperaire (com informações). Este artigo expõe os resultados obtidos com a análise baseada em sequências reducionais do material coletado por Laming-Emperaire em 1961. Os tipos identificados para os Xetás nas poucas publicações, como chooppers e chopping-tools, podem ser associados a outras tradições arqueológicas definidas para região sul, em especial o lítico de grupos ceramistas Proto-Jê e Tupiguarani.
Sobre Arqueologia de Contrato

Published: November 2017

Este artigo revisa os principais argumentos usados para justificar a arqueologia de contrato no mundo. Ao analisá-los contextualmente, no entanto, estes argumentos são desnudados, revelando sua articulação com a lógica da modernidade e do capitalismo. Como estudo de caso é analisado o caso do Brasil, a partir do qual se estabelecem conclusões mais abrangentes.
Arqueologia como Capitalismo do Desastre
Authors: Hutchings Rich , La Salle Marina
Published: November 2017

A arqueologia é uma forma de capitalismo do desastre, caracterizado por gestores especializados cuja função é a “liberação” da herança indígena da paisagem, abrindo o caminho para o desenvolvimento econômico. Quando confrontados com esta crítica, os arqueológicos respondem de maneira forte e emocional, negando e defendendo a indústria da arqueologia comercial. Sua fúria provém e gira em torno da ideia de que os arqueólogos não são apenas cúmplices, mas tomam parte da destruição do mesmo patrimônio que clamam proteger. No que acreditamos ser um ato de autopreservação filosófica e econômica, a maioria dos arqueólogos propositalmente “esquece” a relação entre arqueologia, violência e a crise do patrimônio global. Seguramente defendida por seus praticantes, a arqueologia permanece por este motivo uma força imperial, fundada na ideologia do crescimento, desenvolvimento e progresso.
