Early Storage and Sedentism on the Pacific Northwest Coast: Ancient DNA Analysis of Salmon Remains from Namu, British Columbia
Authors: Cannon Aubrey , Yang Dongya Y.
Published: May 2010

Ancient DNA identification of salmon remains from the site of Namu on the central coast of British Columbia shows use of a variety of species and an emphasis on pink salmon over the course of the past 7,000 years. These results support arguments that Namu was a permanent village settlement dependent on a salmon storage economy throughout this time. This pattern of subsistence and settlement predates by several millennia the first substantial evidence for population expansion or social differentiation in the region. Periodic salmon shortages in the period after 2000 cal B.C., which are associated with local and regional disruptions in settlement and increased reliance on more marginal resources, appear to be the result of failures in the pink salmon fishery.
The Promise and Challenge of Archaeological Data Integration
Authors: Kintigh Keith
Published: May 2010

This forum reports the results of a National Science Foundation—funded workshop that focused on the integration and preservation of digital databases and other structured data derived from archaeological contexts. The workshop concluded that for archaeology to achieve its potential to advance long-term, scientific understandings of human history, there is a pressing need for an archaeological information infrastructure that will allow us to archive, access, integrate, and mine disparate data sets. This report provides an assessment of the informatics needs of archaeology, articulates an ambitious vision for a distributed disciplinary information infrastructure (cyberinfrastructure), discusses the challenges posed by its development, and outlines initial steps toward its realization. Finally, it argues that such a cyberinfrastructure has enormous potential to contribute to anthropology and science more generally. Concept-oriented archaeological data integration will enable the use of existing data to answer compelling new questions and permit syntheses of archaeological data that rely not on other investigators' conclusions but on analyses of meaningfully integrated new and legacy data sets.
Bone Chemistry, Body Parts, and Growth Marks: Evaluating Ohio Hopewell and Cahokia Mississippian Seasonality, Subsistence, Ritual, and Feasting
Authors: Yerkes Richard W.
Published: May 2010

Human stable isotope values and deer utility indices have been used to reconstruct Hopewell and Mississippian diets and subsistence practices, but seasonality studies are also needed to resolve debates about feasting and elite provisioning. Dispersed Hopewell tribes foraged for food and harvested native cultigens. Seasonal feasts at earthworks helped integrate the dispersed populations. Mississippian subsistence cycles are reflected in the seasonal abundance of deposited floral and faunal remains. Pits filled in spring/summer have many fish, but few deer bones. Deer remains are abundant, but fish are rare, in pits filled during the fall/winter. Finding few deer remains in some pits at Cahokia may not mean that deer were scarce but may mean that few deer were hunted during the seasons when those trash pits were filled. Stable isotope values in human burials, analyses of floral and faunal remains from pits and middens filled throughout the year, and diachronic studies of deer size and herd stability indicate that the Cahokia elite consumed a variety of foods including substantial amounts of fish and venison. Patterns in deer element distributions in “elite“” and “non-elite” contexts suggest that venison may have been part of the tribute that was presented to high-status Cahokians.
Ceramic Specialization and Agricultural Marginality: Do Ethnographic Models Explain the Development of Specialized Pottery Production in the Prehistoric American Southwest?
Authors: Harry Karen G.
Published: May 2010

Ethnographic data indicate that historically, ceramic specialization is strongly correlated with agricultural and economic marginality. Where such specialization is concentrated geographically, it often is found in areas having agriculturally poor lands (Arnold 1985). Although this association is well established for modern-day and historic peasant communities, the degree to which this pattern extended into prehistory is unknown. In this paper, I evaluate the applicability of the agricultural marginality model to the prehistoric American Southwest by considering evidence from six areas where specialized pottery production is known to have occurred. The data from these areas suggest that, in the prehistoric Southwest, agricultural marginality was not the primary or sole factor leading to the adoption of part-time ceramic specializations. To understand why the ethnographic model does not apply to the prehistoric Southwest, attention must be focused on understanding the differing social and economic contexts within which prehistoric farmers and historic and modern-day peasants operated.
Archaeological Survey Design, Units of Observation, and the Characterization of Regional Variability
Authors: Sullivan III Alan P. , Mink II Philip B. , Uphus Patrick M.
Published: May 2010

It is generally presumed that intensive survey yields reliable representations of regional archaeological variability. We evaluate this assumption with an analysis of the results of two intensive surveys of the same terrain in the Upper Basin, a heavily forested upland ecosystem located south of Grand Canyon National Park in Kaibab National Forest, northern Arizona. By comparing differences between the results of site-based surveys with those of mapping-unit-based surveys, we demonstrate that units of observation have a profound effect on how archaeological landscapes and their variability are characterized and interpreted. In addition, results of four analyses of survey data show that the archaeological resource inventories created by the application of these two different units of observation cannot be reconciled. We suggest that because some units of observation may be more appropriate for certain problems and for different kinds of surface and near-surface archaeological records, additional studies of the effects of units of observation on characterizing the archaeological content of the same terrain should become a research priority in survey archaeology. Without such studies, the identification of archaeologically sensitive areas, particularly those that necessitate active management and vigilant protection on public lands, will be underdetermined, thereby placing those heritage properties at risk.
Costly Signaling and the Ascendance of No-Can-Do Archaeology: A Reply to Codding and Jones
Authors: McGuire Kelly R. , Hildebrandt William R. , Carpenter Kimberly L.
Published: May 2010

While providing a review of some of the ethnographic literature surrounding hunting and Costly Signaling Theory, Codding and Jones offer no alternative framework for how this emerging theoretical approach might be applied to the archaeological record. In their view, Costly Signaling Theory lies beyond the pale of current archaeological inquiry, or at least our conception of it. We respond to this characterization by providing a specific methodological approach, combined with several additional applications, that answer Codding and Jones's call for greater linkage between the theory and the archaeological record. Ultimately, we believe that the archaeological record, with its temporal dimension, may illuminate some of the underlying aspects of Costly Signaling Theory that are otherwise obscured by more synchronic ethnographic studies.
A Unified Evolutionary Model of Archaeological Style and Function Based on the Price Equation
Authors: Brantingham P. Jeffrey
Published: May 2010

The style-function dichotomy lies at the heart of the evolutionary archaeology research program. It also is the source of much disagreement about how we should conceive of the processes of culture change. Evolutionary archaeologists tend to view archaeological attributes as either functional, if they respond to selection, or stylistic, if they do not. Others tend to see style and function as operating simultaneously. A resolution to this problem is proposed through development of a formal mathematical model of style- and function-based evolution using a hypothetical example of temporal patterns of ceramic decoration within a community of household-based potters. Simple replicator equations are proposed to describe the household-scale dynamics of change in the relative frequency of ceramic decoration. These low-level dynamics can be distinguished on the basis of whether or not change is correlated with some measure of performance, utility, or payoff. The replicator equations are then used to derive several versions of the Price Equation (Price 1970), a very general and powerful statement about total evolutionary change in any system. At this scale of analysis, total change is similarly partitioned into payoff-correlated (functional) and payoff-independent (stylistic) contributions and it is shown that these processes are likely to operate simultaneously. Tests of the model against simulated data show that it is possible to estimate with considerable accuracy the strength of functional and stylistic contributions to culture change under ideal conditions of site preservation. Further theoretical work is needed, however, to understand how diverse site formation and disturbance processes might impact application of the model in real archaeological settings.
Single Component Sites with Long Sequences of Radiocarbon Dates: The Sunwatch Site and Middle Fort Ancient Village Growth
Authors: Cook Robert A.
Published: May 2010

Radiocarbon dates from single-component prehistoric sites often span temporal sequences too long to be accounted for by spatial overlap in the patterning of features. One such example is the SunWatch site, which was long interpreted as a single-component occupation of relatively short duration (15–20 years), although the radiocarbon sequence comfortably spans a 500-year period (ca. A.D. 1000 to 1500). This study compares spatial contexts of the SunWatch radiocarbon dates with other temporal indicators, including architectural rebuilding, feature form and volume, and diagnostic artifact attributes. Two distinct portions of the radiocarbon sequence can be accounted for by reference to these other lines of evidence. Village growth is linked with internal and external processes, including the arrival of a small Mississippian group and the possibility of site reoccupation, common among shifting agricultural systems.
Reduction Strategies and Geochemical Characterization of Lithic Assemblages: A Comparison of Three Case Studies from Western North America
Authors: Eerkens Jelmer W. , Ferguson Jeffrey R. , Glascock Michael D. , Skinner Craig E. , Waechter Sharon A.
Published: May 2010

Based on a simple model of lithic procurement, reduction, and use, we generate predictions for patterns in source diversity and average distance-to-source measurements for flaked stone assemblages left behind by small-scale and residentially mobile populations. We apply this model to geochemical data from obsidian artifacts from three regions in western North America. As predicted, results show markedly different patterns in the geochemical composition of small flakes, large flakes, and formal tools. While small flakes and tools tend to have greater source diversity and are on average farther from their original source, the large flake assemblage is composed of fewer and closer sources. These results suggest that a failure to include very late stage reduction (e.g., pressure flakes) and microdebitage in characterization studies may bias interpretations about the extent of residential mobility and/or trade patterns because more distant sources will be underrepresented.
Food, Meals, and Daily Activities: FoodHabitusat Neolithic Çatalhöyük
Authors: Atalay Sonya , Hastorf Christine A.
Published: May 2010

We consider the daily practices of food preparation and consumption at the Neolithic Anatolian site of Çatalhöyük. We present the major food activities suggested from the archaeological evidence, including the timing and range of possible ingredients eaten by the residents of this thousand-year settlement. Plant, animal, and mineral resources, as well as the food production and preparation practices, are viewed in the context of the seasonal cycle. The food-related activities practiced at Çatalhöyük within each of the seasons are placed into five primary groups: production and procurement, processing, cooking, presentation, and eating. The daily household acts associated with these categories are discussed in detail. Using flora, fauna, micromorphological, lithic, ceramic, clay and architectural evidence, we present a picture of a community that was relatively healthy. The residents had a diet that relied heavily on plant foodstuffs, with wild plants remaining an important and valuable part of the daily and seasonal food practices throughout. The people of Çatalhöyük ate a range of animal products, including meat obtained from domesticated sheep/goats, wild cattle, small and large game, and to a more limited extent, eggs and waterfowl. Their social life can be seen through these foodways.
Projectile Point Shape and Durability: The Effect of Thickness: Length
Authors: Cheshier Joseph , Kelly Robert L.
Published: May 2010

We describe an experiment that tests the hypothesis that projectile points with high thickness: length ratios are more durable than points with low thickness: length ratios. Fifty obsidian projectile points were manufactured to specific lengths, widths, and thicknesses. These were then fired into a deer carcass with a bow repeatedly until each point broke. None of the points were resharpened. The hardness of the material struck was a significant predictor of a point's durability. Controlling for this variable, however, we found that points with a high thickness: length ratio (>.121) were slightly albeit significantly more durable than those with a low ratio. No other attribute of size or shape was a significant predictor of durability.

Authors: Freisinger Eva
Published: May 2010

While structures of mammalian metallothioneins and their metal-thiolate clusters have been known for nearly 20 years, the first three-dimensional structure of a plant metallothionein was only published very recently. Also in other aspects, research on plant metallothioneins lags behind
what is known about the vertebrate forms. However, in the past years more and more information, mostly based on experiments performed with optical spectroscopy has become available and permit sometimes unforeseen insights. In the following, the different experimental strategies applied in
our laboratory will be described together with the progress we have made over the past years in detecting and characterizing the metal-thiolate clusters of plant metallothioneins.
Understanding Selective Oxidations
Authors: Neuenschwander Ulrich , Turrà Natascia , Aellig Christof , Mania Philipp , Hermans Ive
Published: May 2010

Functionalizing organic molecules is an important value-creating step throughout the entire chemical value-chain. Oxyfunctionalization of value-chain. Oxyfunctionalization of e.g. C–H or C=C bonds is one of the most important functionalization technologies used industrially.
The major challenge in this field is the prevention of side reactions and/or the consecutive over-oxidation of the desired products. Despite its importance, a fundamental understanding of the intrinsic chemistry, and the subsequent design of a tailored engineering environment, is often missing.
Industrial oxidation processes are indeed to a large extent based on empirical know-how. In this mini-review, we summarize some of our previous work to help to bridge this knowledge gap and elaborate on our ongoing research.
Implementing Literacy Coaching
Authors: Matsumura Lindsay Clare , Garnier Helen E. , Resnick Lauren B.
Published: May 2010

This study investigates the influence of a school’s pre-existing social resources on the implementation of a comprehensive literacy-coaching program (Content-Focused Coaching [CFC]). Elementary schools were randomly assigned to receive a CFC-trained coach ( n = 15 schools) or to continue with the literacy coaching resources that are standard for the district ( n = 14 schools). Ninety-six fourth- and fifth-grade teachers participated in the study ( n = 63 CFC and n = 33 comparison). Survey results indicate that teachers in the CFC schools participated more frequently in the coaching activities that emphasized planning and reflecting on instruction, enacting instruction, and building knowledge of the theories underlying effective reading comprehension instruction compared to teachers in the comparison schools. After 1 year, teachers strongly believed that CFC coaching helped improve their instructional practice. Principal leadership was the key resource supporting implementation of the program positively predicting greater teacher participation in coaching activities and perceived usefulness of these activities along with coaches’ training in the CFC program and less experienced teachers. Unexpectedly, a school’s pre-existing culture of teacher collaboration negatively predicted teachers’ coaching experiences. CFC coach interviews contribute to understanding the interactions of social resources within schools that facilitated or hindered program implementation. Implications for the design and implementation of effective instructional coaching policies in districts are discussed.
Adolescent Propensity to Engage in Health Risky Behaviors: The Role of Individual Resilience
Authors: Ali Mir M. , Dwyer Debra S. , Vanner Elizabeth A. , Lopez Alexander
Published: May 2010

In this paper we create indices of resilience to identify adolescents at risk of smoking, drinking alcohol, and using illegal drugs. Using data from the National Longitudinal Study of Adolescent Health, three manifestations of resilience were identified: overall-resilience, self/family-resilience, and self-resilience. Our analysis reveals that the overall-resilient were less likely to engage in risky behaviors. The self/family resilient were more likely to engage in risky behaviors, but consumed less. The self-resilient had reduced risk for smoking and drinking alcohol but elevated risk for using illegal drugs and being in an addictive stage of smoking and drinking, if participating.

Published: May 2010

Arylhydrazonomalononitriles 1a,b react with phenylhydrazine to yield amidrazones 2a,b that cyclize to give 2-aryl-5-phenylhydrazono-2,5-dihydro-[1,2,4]-triazine-6-carbonitriles 5a,b upon reaction with dimethylformamide dimethylacetal (DMFDMA). Refluxing 5a,b in glacial acetic acid resulted in the formation of the pyrazolo-1,2,4-triazines 6a,b. Compounds 6a,b were also formed upon treatment of 3-amino-4-phenylhydrazono-1-phenyl-2-pyrazolin-5-ones 7a,b with DMFDMA. Reacting these triazinyl arylhydrazononitriles 5a,b with hydroxylamine hydrochloride in ethanolic sodium acetate afforded amidrazones 8a,b that are readily cyclized in refluxing dimethylformamide into [1,2,4]triazino[1,2,3]triazines 10a,b.
The Relationship between Ultraviolet Radiation Exposure and Vitamin D Status
Authors: Engelsen Ola
Published: May 2010

This paper reviews the main factors influencing the synthesis of vitamin D, with particular focus on ultraviolet radiation exposure. On the global level, the main source of vitamin D is the sun. The effect of solar radiation on vitamin D synthesis depends to some extent on the initial vitamin D levels. At moderate to high latitudes, diet becomes an increasingly important source of vitamin D due to decreased solar intensity and cold temperatures, which discourage skin exposure. During the mid-winter season, these factors result in decreased solar radiation exposure, hindering extensively the synthesis of vitamin D in these populations.
Time Delay for Aerial Ammonia Concentration Measurements in Livestock Buildings
Authors: Rom Hans Benny , Zhang Guo-Qiang
Published: May 2010

Correct measurements of ammonia concentration in air still present considerable challenges. The high water solubility and polarity can cause it to adsorb on surfaces in the entire sampling system, including sampling lines, filters, valves, pumps and instruments, causing substantial measuring errors and time delays. To estimate time delay characteristics of a Photo Acoustic Multi Gas Monitor 1312 and a Multi Point Sampler continuous measurement of aerial ammonia concentrations at different levels was performed. In order to obtain reproducible data, a wind tunnel was used to generate selected concentrations inside and a background concentration representing the air inlet of the tunnel. Four different concentration levels (0.8 ppm, 6.2 ppm, 9.7 ppm and 13.7 ppm) were used in the experiments, with an additional outdoor concentration level as background. The results indicated a substantial time delay when switching between the measuring positions with high and low concentration and vice versa. These properties may course serious errors for estimation of e.g. gas emissions whenever more than one measuring channel is applied. To reduce the measurement errors, some suggestions regarding design of the measurement setup and measuring strategies were presented.
What Kind of Trait the Entrepreneur Needs to Possess?
Authors: Hui Su
Published: May 2010

Leader can be regarded as the core resource and soul of the enterprise, because the leader is charged of making policies and strategies, which would affect the development orientation of the enterprise. To further analyze, the trait and character of a leader would directly decide what kind of strategies or actions would be adopted facing the given situation. In practice we can see that the successful leaders express some common things and traits, which would be meaningful to analyze the trait that successful leaders own, and to analyze what kind of trait the entrepreneur needs to possess. Relevant literatures and investigations were cited in this paper to make the research more persuasive. On the basis of literature review, a two-layer leader traits model was brought forward, which classify the leader’s needed traits into two groups, one is basic traits that would be remain constant from time to time. The other is changeable group that would be affected by the particular economic and social situation and needn’t to be persisted in. Then we make further analyze on the domestic entrepreneurs needed traits on the basis of the existed investigation. Relevant basic traits and changeable traits were drawn on the basis of the conclusion of the investigation made by the task Group of enterprise research institute. The conclusion of this paper would be meaningful for the selection and cultivation of leaders and entrepreneurs in China.

Gear Multi-Faults Diagnosis of a Rotating Machinery Based on Independent Component Analysis and Fuzzy K-Nearest Neighbor
Authors: Li Zhi Xiong , Yan Xin Ping , Yuan Cheng Qing , Li Li
Published: May 2010

Gearboxes are extensively used in various areas including aircraft, mining, manufacturing, and agriculture, etc. The breakdowns of the gearbox are mostly caused by the gear failures. It is therefore crucial for engineers and researchers to monitor the gear conditions in time in order to prevent the malfunctions of the plants. In this paper, a condition monitoring and faults identification technique for rotating machineries based on independent component analysis (ICA) and fuzzy k-nearest neighbor (FKNN) is described. In the diagnosis process, the ICA was initially employed to separate characteristic vibration signal and interference vibration signal from the parallel time series obtained from multi-channel accelerometers mounted on different positions of the gearbox. The wavelet transform (WT) and autoregressive (AR) model method then were performed as the feature extraction technique to attain the original feature vector of the characteristic signal. Meanwhile, the ICA was used again to reduce the dimensionality of the original feature vector. Hence, the useless information in the feature vector could be removed. Finally, the FKNN algorithm was implemented in the pattern recognition process to identify the conditions of the gears of interest. The experimental results suggest that the sensitive fault features can be extracted efficiently after the ICA processing, and the proposed diagnostic system is effective for the gear multi-faults diagnosis, including the gear crack failure, pitting failure, gear tooth broken, compound fault of wear and spalling, etc. In addition, the proposed method can achieve higher performance than that without ICA processing with respect to the classification rate.

Finite Element Analysis of a Certain Reducer Gear
Authors: Qian Wen Xue , Yin Xiao Wei , Xie Li Yang
Published: May 2010

Gears are key rotor components of many machines and are widely used in many engineering fields such as mining machinery, aerospace; transportation and petrochemical etc, and their failure often cause disastrous results. In practical engineering, it is still tedious to assess gears strength and the stress levels of them are very high nowadays. It is well known that the stress analysis is a basic work of age analysis and reliability analysis. Do a finite element analysis (FEA) is necessary before and after the gears have been made. In this paper, a detail analysis is done with FEA, and the stress distribution of gear is consistent with the real distribution. Also the FEA results show that the location of maximum stress is just the failure site of the gear. The analysis results are meaningful for further work such as reliability assessment and optimization design.

The structural durability of wheel loader are required to estimate on the basis of design loading spectrum, which is a spectrum combination of various operating and loading conditions. To generate the load spectrum of transmission system, an actual operational loads of wheel loader under the driving cycle was investigated. A signal collection system was applied to get time-history voltage signals and then torque loads were obtained according to the conversion coefficient between voltage and torque. After zeroing and filtering, the mean, the amplitude and number of load cycles were gained with the rain-flow counting method. The mean and amplitude were tested by Nominal distribution and Weibull distribution respectively. Test results show that they are independent. The two-dimensional joint probability density function of amplitude and mean was gained. After extrapolation, the load spectrum of the spacerflange under whole-life cycle is gained and the process of compiling load spectrum is also provided.

A Hybrid Differential Evolution Algorithm for Binary CSPs
Authors: Fu Hong Jie
Published: May 2010

A novel hybrid elements exchange/electromagnetism meta-heuristic differential evolution algorithm, named EEMDE, is proposed in this paper, avoiding the premature convergence of original DE algorithm. A metric to measure the Simplification of force exerted on a point is defined as the mutation rate F in the EEMDE, which is used to get an adaptive adjustment of F. EEMDE may produce slight disturbance on the original vector for enhancing the exploring capacity and avoid the DE to the "uphill" in the wrong direction forward. Experiments demonstrate that the convergence of EEMDE is faster than DE and simulations based on some CSPs express the effectiveness, efficiency and robustness of it.

Fault Tolerance Design by Accurate SER Estimation Based on Ensemble Transform Matrix
Authors: Yu Chang Hong
Published: May 2010

With development of CMOS process, the minimum lithographic feature has now scaled down to regime of nano-scale. Integrated circuits (ICs) are becoming increasingly susceptible to uncertainty caused by soft errors, inherently probabilistic devices, and manufacturing variability. With all kinds of faults and errors, soft error is the most common and widespread. The different design methodology can reach different soft error tolerance ability, so we must find a way to estimate the soft error rate (SER) efficiently to make the design more fault tolerant. In this paper, we propose and investigate the ensemble transform matrix model. We show that the model can describe the actual nano-scale circuit performance. We also propose criteria to evaluate the circuits’ soft error tolerance capability. Simulation shows that the proposed ensemble transform matrix model is effective and suitable for CAD tools development in nano-scale circuit and system design.
