The aim of this study is to examine the relationship between metric variability of ceramic vessels of a single type and intensity of production. This relationship is examined on the basis of vessels made by Indian and Spanish potters whose rates of production vary from low to high. Results are compared with Filipino data to embrace different cultures and therefore possibly different emic conceptions of standardization. We conclude that rate of production affects the degree of standardization. However, only in a high-rate production situation do we have motor habits that transcend emic conceptions of standardization. Indeed, factors like size classes, emic conception of size classes, and skill may induce a certain variability despite similar rates of production. Indexing degrees of standardization needs, in other respects, to take into account the cumulative effect of production events that play on the CV (Coefficient of Variation) values. Applied to Mesopotamian data, our results suggest that third millennium ceramic production can be compared to low-rate production observed ethnographically.

Low-rate (6 ml/h) intragastric infusion of stable, isotope-labeled amino acids is commonly used to assess the splanchnic handling of amino acids in humans. However, when used in the postabsorptive state, this method yields unreliable plasma isotopic enrichments, with a coefficient of variation >10%. In this metabolic condition, we confirmed in six subjects that an intragastric infusion of l-[2H3]leucine at 6 ml/h yields an unreliable isotopic steady state in plasma amino acids with a coefficient of variation of 43 ± 12% (mean ± SD). In five additional subjects, we assessed the effects of 1) increasing the rate of delivery of a leucine tracer in an isotonic plasmalike solution at 240 ml/h into the gastric site, and 2) changing the site of infusion from gastric to duodenal with this same high rate of delivery. In contrast to the gastric route, and regardless of the rate of delivery, only the intraduodenal route allowed 1) isotopic plasma steady state (i.e., coefficients of variation were <10%: 5 ± 3%), and 2) reproducible leucine extraction coefficients (22 ± 5%). We conclude that an infusion site that bypasses the gastric emptying process, i.e., the duodenal route, along with delivery of a plasmalike solution, is necessary to reach isotopic steady state in plasma when labeled leucine is infused into the gastrointestinal tract in the postabsorptive state.

Abstract Tread wear rates during first wear measured by groove depth and weight changes do not always agree. Sometimes, the groove depth method shows a high rate and the weight loss method a low rate. Reported here are experiments designed to determine if grooves show depth changes without wear. Four tires were measured before mounting on a wheel, after mounting and inflation, and after inflation and storage. The mounted and inflated tires showed shallower shoulder grooves and deeper center grooves than the unmounted tires. In a second experiment, tires were measured immediately after a tread wear test and then stored mounted for two weeks before remeasuring. Each groove became deeper, and there was no change in the crown radius of any tire.

We propose a multi-temporal-scale analysis of ground deformation data using both high-rate tilt and GNSS measurements and the DInSAR and daily GNSS solutions in order to investigate a sequence of four paroxysmal episodes of the Voragine crater occurring in December 2015 at Mt. Etna (Italy). The analysis aimed at inferring the magma sources feeding a sequence of very violent eruptions, in order to understand the dynamics and to image the shallow feeding system of the volcano that enabled such a rapid magma accumulation and discharge. The high-rate data allowed us to constrain the sources responsible for the fast and violent dynamics of each paroxysm, while the cumulated deformation measured by DInSAR and daily GNSS solutions, over a period of 12 days encompassing the entire eruptive sequence, also showed the deeper part of the source involved in the considered period, where magma was stored. We defined the dynamics and rates of the magma transfer, with a middle-depth storage of gas-rich magma that charges, more or less continuously, a shallower level where magma stops temporarily, accumulating pressure due to the gas exsolution. This machine-gun-like mechanism could represent a general conceptual model for similar events at Etna and at all volcanoes.

This study shows a comparison of important parameters for dynamic simulation concerning the highrate and low-rate activated sludge tanks of several municipal wastewater treatment plants. The parameters for the dynamic simulation of the single-stage process are quite well known, but parameters for the high-ratellow-rate activated sludge process are still missi ng, although a considerable number of wastewater treatment plants are designed and operated that way. At present any attempt to simulate their operation is restricted to the second stage due to missing data concerning growth rate, decay rate, yield coefficient and others.

The Relationship

Before 1991, the relationship between the protection of the environment and international trade was an arcane specialty that attracted little attention. In 1971 the GATT Council established a Working Group on Environmental Measures and International Trade. This group did not even meet for over twenty years.Everything changed with the decision in the Tuna/Dolphin I case, in which a GATT dispute resolution panel declared a United States embargo on tuna caught by fishing methods causing high dolphin mortality to be illegal. The Tuna/Dolphin I decision produced an explosion of rhetoric in both learned journals and the popular press. It was also a very interesting clash of very different “cultures,” trade specialists versus environmentalists. At die outset, neither group knew much about the other. Now, however, the legal and political issues have been identified and ventilated, mutual understanding has increased, and the process has begun to reconcile two values that are absolutely essential to the well-being of mankind: protection of the environment and international free trade.

The present experiment investigated the effects of noncontingent nonreinforcement as the aversive event in a CER paradigm. The results showed a significant response-facilitation effect during early training, but none during later training with a high rate-producing, high-density reinforcement schedule. The present results imply that a low rate-producing, high-density reinforcement schedule is not a necessary condition for response facilitation.

Hospital Cardiac Arrest

Introduction : Early bystander C.P.R., A.E.D. use and continuous chest compressions are essential elements of the a.h.a. “chain of survival”. Bystander C.P.R. and A.E.D. use in urban settings are becoming more prevalent. The use of an automated load distributing band (l.d.b.) device for O.H.C.A. management in a large metropolitan area by paramedics was implemented in the winter of 2007; in 9 municipalities, 582 paramedics were trained to use the l.d.b. device as part of a.l.s. measures. A retrospective paramedic “run-sheet” review was performed from 4/2008 - 8/2009 for all nontraumatic adult cardiac arrests. R.O.S.C. on arrival to the emergency departments (e.d.) was the endpoint. Methods: 86 adult nontraumatic O.H.C.A. rehorts were found. each of the prehospital reports were reviewed. Utstein data elements were collected. bystander C.P.R. with “caller-aided” dispatch, A.E.D. use, paramedic use of standard a.h.a. resuscitation alogarthythms in addition to use of an automated l.d.b. device use (auto pulse® zoll) was recorded. Minitab 15 statistical software was used to evaluate the data. The cumulative effect of sequential “chain-of-survival” components was calculated. Results: the mean age was 63 Y.O.; there were 58 males and 28 females. The initial rhythm was: v.fib, pulseless v.tach, P.E.A., or asystole. Chain of survival cumulative synergistic effect on R.O.S.C. Conclusion: When bystander C.P.R., in addition to A.E.D. and autopulse were utilized synegistically, R.O.S.C. on e.d. arrival was 71%. When bystander C.P.R. and autopulse were used (without A.E.D. use) only 49% of patients had R.O.S.C. on e.d. arrival. Which is higher than previously reported: Hallstrom et al. (2006): 26% and Ong et al. (2006): 35%. When the l.d.b. device was used with a.l.s., R.O.S.C. was only 20%; which may be due to delayed care; since no efforts were made to resuscitate patients until the paramedics arrived. Our data reaffirms that early bystander C.P.R. and A.E.D. use are essential for achieving a high rate of R.O.S.C.

Purpose The purpose of this paper is to examine the effects of cultural differences and the types of relationship closeness involved in recipients’ emotional and behavioral reactions after receiving disliked gifts. Design/methodology/approach Collecting data from Thailand and the USA, two experiments were conducted in a 2 (self-construal: independent/interdependent) × 2 (relationship closeness: close/distant) between-subjects design. Study 1 explores the recipients’ feelings and reactions upon receipt of a disliked gift. Study 2 explores the disposition process for a disliked gift. Findings The results show that a recipient’s emotions, reaction and disposition process can be affected by cultural differences and relationship closeness: specifically that close and distant relationships moderate the relationship between self-construal and gift-receiving attitudes and behaviors. Research limitations/implications Future research can investigate representative groups from other countries to broaden the generalizability of the findings. Practical implications This understanding can guide gift-givers when selecting gifts for close or distant recipients across cultures. Additionally, it can help retailers develop and introduce new marketing strategies by applying self-construal as a marketing segmentation tool for gift purchase and disposition. Originality/value This research is among the first studies to offer insights into how individuals in different cultures manage disliked gifts they receive from people in either close or distant relationships.

The Relationship

The socio-legal perspective on the alcohol legislation, including the norms concerned with the relationship between individuals and alcoholic drinks, helps answering some essentials questions: what was/is the "social construction" of the alcohol problem in different eras and different cultures and, consequently, which objectives are deemed to be worthy of pursuit through the creation or amendment of legislation? Which social actors have the ability, in a given period of time, to inscribe the relevance of innovative alcohol legislation on the political agenda and what kind of dialectic is used among those who champion points of view, competences and above all, different interests? Which interests and values would appear to meet with legislatory protection time after time? What tools, of the ample range available, are chosen to achieve the aims set out? To what extent is legislation implemented (or not implemented), and why? Which aspects of the implementation process prove to be most significant, i.e. define the actual content of the legislation "in force", and are therefore tangibly experienced by the law's end target? How much of an impact does legislation have on behavior which is subject to regulation or on problems which stem from such behavior?
