The site at Red Barns was excavated in 1975, but the large lithic collection remained unstudied following preliminary examination. This paper reports on further analysis of the lithic material from the site, together with a reappraisal of the faunal remains and original mineralogical analyses, and the results of processing sediment samples from the 1975 excavation. An abundant molluscan assemblage was recovered from the deposits covering the main archaeological horizon, allowing climatic/environmental reconstruction and amino acid dating. The synthesis of these data indicates the site to be older than previously thought, dating to between 425,000 and 200,000 BP.Analysis of the lithic material has suggested that the site is an undisturbed palimpsest of flint tools and debitage. The poor, severely frost-fractured nature of the raw material used for knapping, together with the location of the site on a Chalk outcrop, have enabled investigation of some assumptions about the influences upon knapping technology of i) poor quality raw material and ii) local availability of flint fresh from Chalk bedrock. The persistent manufacture of finely worked plano-convex handaxes suggests that, even in an area where fresh Chalk flint must have been abundant, the immediately available poor quality flint source was not a bar to formation of an assemblage dominated by handaxe production. Secondly, the emphasis on carefully shaped pointed plano-convex handaxes suggests that this shape was both deliberately imposed and not dictated by a lack of local availability of flint fresh from the Chalk. Behaviour at the site was investigated by analysis of the organisation of the lithic production and it was demonstrated that, while some handaxes and flake-tools were abandoned at the site and some flake core reduction also took place there, the dominant pattern was for handaxes to be made at the site and then removed and abandoned elsewhere.

The Azé Cave (Sâone-et-Loire, France) has yielded, among other archaeological and palaeontological remains, a Lower Palaeolithic industry within a layer dated through faunal remains to 400–350 kya. This industry is made up of local rocks, mostly poor quality flint, and also chert and crystalline rocks.Only flint was definitely knapped; chert was only broken into pieces before being used. The process of knapping is opportunistic and the cores, seldom exhausted, usually bear two opposite reduction faces. The flakes often reveal patches of residual cortex. They are moderately thick and the striking platform angle varies within a wide range of values. Some of them seem to be the result of a tearing-off motion. All the flint pieces have been heavily retouched; half of them have been simply utilised, others are proper tools, mostly scrapers, usually with steep retouch. Fragments of chert, sometimes obtained by tearing-off (from the cave walls?) have been often retouched but with less intensity than the flint. A good number of more or less trimmed cobbles are also part of this collection. However, handaxes are completely missing.The lithic industry of Azé 1–1 lacks standardisation for the core reduction process as well as for trimming or retouching. It fits well in the Lower Palaeolithic industry but the absence of handaxes is noteworthy. This industry offers one more contribution to the diversity of this cultural period.

The NIR reflection spectra of some purified conifer resin extracts used as a biologically active ingredient in pharmaceutical ointments were employed to reveal the possibility of applying NIR spectroscopy to quality control. The samples were analysed beforehand (by HPLC and compendial methods) in order to characterise them. The fingerprint of this raw material was achieved by using the standard methods recommended by the NSAS operating protocol (for the spectrometer delivered by NIRSystems Inc.). The poor quality samples were also tested by means of same protocol, the limits of method being pointed out.

Meda is one of the most important plants included in Astavarga. This plant is used in variety of Ayurvedic formulations such as Cyavanprasa. Dried underground parts (rhizomes) of this plant are used for medicinal purpose. This plant is claimed to possess rejuvenating, health promoting, immune system strengthening, anti-oxidant and cell regenerating properties. Also claimed to promote body fat, healing fractures, control fever, abdominal thirst, diabetic condition, seminal weakness, and as a cure for Vata, Pitta and Rakta dosa. The demand of this herb is increasing day by day but due to scarcity of this plant in wild, unaware about authentic botanical source, non-existing cultivation practices there is widespread problem of adulteration or substitution with other plants. The poor quality of raw material affect the quality of end product formed. So by taking into account the above situation this systematic review/ metadata analysis has conducted to find out adulteration in Meda.

The article discusses the experience of teaching and conducting spirometry of general practitioners as part of the RESPECT study (RESearch on the PrEvalence and the diagnosis of COPD and its Tobacco-related aetiology). A total of 33 trained in spirometry general practitioners performed a study of 3119 patients. Quality criteria met 84.1% of spirometric studies. The analysis of the most common mistakes made by doctors during the forced expiratory maneuver is included. The most frequent errors were expiration exhalation of less than 6s (54%), non-maximal effort throughout the test and lack of reproducibility (11.3%). Independent predictors of poor spirogram quality were male gender, obstruction (FEV1 /FVC<0.7), and the center where the study was performed. The number of good-quality spirograms ranged from 96.1% (95% CI 83.2–110.4) to 59.8% (95% CI 49.6–71.4) depending on the center. Subsequently, an analysis of the reasons behind the poor quality of research in individual centers was conducted and the identified shortcomings were eliminated. The poor quality of the spirograms was associated either with the errors of the doctors who undertook the study or with the technical malfunctions of the spirometer.

The shift to an integrated IBS construction approach requires enhanced supply chain integration to improve the productivity as well as the poor quality of human behavioual aspect in IBS project. This paper is to identify the challenges at each tier between players to facilitate supply chain integration among the IBS players. Findings adopted from semi-structured interview revealed the critical attitude issues of human factors, lack of interaction and sharing knowledge between interdisciplinary people. The findings of this study is useful to improve integration of supply chain and enhance innovation and sharing interaction between players in the IBS Malaysian construction project environment.© 2016.

The quality of metadata is a crucial determinant of usability/interpretability of data. This paper draws attention to the poor quality of India’s government statistics and the paucity of metadata necessary to understand the problems. The paper suggests that there has been a decline in India both in terms of the availability and quality of metadata for key government sources of information including maps, decennial population censuses and National Sample Surveys amidst growing sophistication in the understanding of metadata. The poor quality of metadata impairs cross-sectional as well as inter-temporal comparisons and policymaking apart from concealing biases and lapses of government statisticians. The paper draws on the experience of three states – erstwhile Jammu and Kashmir, Manipur and Nagaland – where government statistics have been affected by serious errors that are not well-understood due to the lack of adequate metadata.

The micro-model, which the brick and the mortar model are separated, is used to analyze masonry. Meanwhile, the mortar is divided into three layers along the thickness direction to obtain the internal mechanical behavior of mortar, and the vertical mortar joint strength is taken as 50% strength of the horizontal mortar joint for considering the poor quality of vertical mortar joint. The compressive ultimate load and failure mode of masonry taken from the finite element analysis result, especially the vertical cracks throughout all bricks and mortar and change of brick and mortar strain, are in agreement with the experimental results. It shows that the micro-model and method adopted in paper are able to effectively apply in nonlinear structural analysis for masonry.

The Science of Language, published in the sixth decade of Noam Chomsky's linguistic career, defends views that are visibly out of touch with recent research in formal linguistics, developmental child psychology, computational modeling of language acquisition, and language evolution. I argue that the poor quality of this volume is representative of the serious shortcomings of Chomsky's recent scholarship, especially of his criticism of and contribution to debates about language evolution. Chomsky creates the impression that he is quoting titbits of a massive body of scientific work he has conducted or is intimately familiar with. Yet his speculations reveal a lack of even basic understanding of biology, and an unwillingness to engage seriously with the relevant literature. At the same time, he ridicules the work of virtually all other theorists, without spelling out the views he disagrees with. A critical analysis of the ‘Galilean method’ demonstrates that Chomsky uses appeal to authority to insulate his own proposals against falsification by empirical counter-evidence. This form of discourse bears no serious relation to the way science proceeds.

The quality of 68 samples of 15 different essential children’s medicines sold in licensed medicine outlets in the Ashanti Region, Ghana, was evaluated. Thirty-two (47.1%) of the medicines were imported, mainly from India (65.6%) and the United Kingdom (28.1%), while 36 (52.9%) were locally manufactured. The quality of the medicines was assessed using content of active pharmaceutical ingredient (API), pH, and microbial limit tests, and the results were compared with pharmacopoeial standards. Twenty-six (38.2%) of the samples studied passed the official content of API test while 42 (61.8%) failed. Forty-nine (72.1%) of the samples were compliant with official specifications for pH while 19 (27.9%) were noncompliant. Sixty-six (97.1%) samples passed the microbial load and content test while 2 (2.9%) failed. Eighteen (26.5%) samples passed all the three quality evaluation tests, while one (1.5%) sample (CFX1) failed all the tests. All the amoxicillin suspensions tested passed the three evaluation tests. All the ciprofloxacin, cotrimoxazole, flucloxacillin, artemether-lumefantrine, multivitamin, and folic acid samples failed the content of API test and are substandard. The overall API failure rate for imported products (59.4%) was comparable to locally manufactured (63.9%) samples. The results highlight the poor quality of the children’s medicines studied and underscore the need for regular pharmacovigilance and surveillance systems to fight this menace.

Abstract Substandard and falsified medications are a major threat to public health, directly increasing the risk of treatment failure, antimicrobial resistance, morbidity, mortality and health expenditures. While antimalarial medicines are one of the most common to be of poor quality in low- and middle-income countries, their distributional impact has not been examined. This study assessed the health equity impact of substandard and falsified antimalarials among children under five in Uganda. Using a probabilistic agent-based model of paediatric malaria infection (Substandard and Falsified Antimalarial Research Impact, SAFARI model), we examine the present day distribution of the burden of poor-quality antimalarials by socio-economic status and urban/rural settings, and simulate supply chain, policy and patient education interventions. Patients incur US$26.1 million (7.8%) of the estimated total annual economic burden of substandard and falsified antimalarials, including $2.3 million (9.1%) in direct costs and $23.8 million (7.7%) in productivity losses due to early death. Poor-quality antimalarials annually cost $2.9 million to the government. The burden of the health and economic impact of malaria and poor-quality antimalarials predominantly rests on the poor (concentration index −0.28) and rural populations (98%). The number of deaths among the poorest wealth quintile due to substandard and falsified antimalarials was 12.7 times that of the wealthiest quintile, and the poor paid 12.1 times as much per person in out-of-pocket payments. Rural populations experienced 97.9% of the deaths due to poor-quality antimalarials, and paid 10.7 times as much annually in out-of-pocket expenses compared with urban populations. Our simulations demonstrated that interventions to improve medicine quality could have the greatest impact at reducing inequities, and improving adherence to antimalarials could have the largest economic impact. Substandard and falsified antimalarials have a significant health and economic impact, with greater burden of deaths, disability and costs on poor and rural populations, contributing to health inequities in Uganda.
