Objective:
To characterize postextraction antibiotic prescribing patterns, predictors for antibiotic prescribing and the incidence of and risk factors for postextraction oral infection.
Design:Retrospective analysis of a random sample of veterans who received tooth extractions from January 1, 2017 through December 31, 2017.
Setting:VA dental clinics.
Patients:Overall, 69,610 patients met inclusion criteria, of whom 404 were randomly selected for inclusion. Adjunctive antibiotics were prescribed to 154 patients (38.1%).
Intervention:Patients who received or did not receive an antibiotic were compared for the occurrence of postextraction infection as documented in the electronic health record. Multivariable logistic regression was performed to identify factors associated with antibiotic receipt.
Results:There was no difference in the frequency of postextraction oral infection identified among patients who did and did not receive antibiotics (4.5% vs 3.2%; P = .59). Risk factors for postextraction infection could not be identified due to the low frequency of this outcome. Patients who received antibiotics were more likely to have a greater number of teeth extracted (aOR, 1.10; 95% CI, 1.03–1.18), documentation of acute infection at time of extraction (aOR, 3.02; 95% CI, 1.57–5.82), molar extraction (aOR, 1.78; 95% CI, 1.10–2.86) and extraction performed by an oral maxillofacial surgeon (aOR, 2.29; 95% CI, 1.44–3.58) or specialty dentist (aOR, 5.77; 95% CI, 2.05–16.19).
Conclusion:Infectious complications occurred at a low incidence among veterans undergoing tooth extraction who did and did not receive postextraction antibiotics. These results suggest that antibiotics have a limited role in preventing postprocedural infection; however, future studies are necessary to more clearly define the role of antibiotics for this indication.

Intensive field surveys were conducted in eastern Nebraska to determine the frequency distribution model and associated parameters of broadleaf and grass weed seedling populations. The negative binomial distribution consistently fit the data over time (1992 to 1993) and space (fields) for both the inter and intrarow broadleaf and grass weed seedling populations. The other distributions tested (Poisson with zeros, Neyman type A, logarithmic with zeros, and Poisson-binomial) did not fit the data as consistently as the negative binomial distribution. Associated with the negative binomial distribution is a k parameter. k is a nonspatial aggregation parameter related to the variance at a given mean value. The k parameter of the negative binomial distribution was consistent across weed density for individual weed species in a given field except for foxtail spp. populations. Stability of the k parameter across field sites was assessed using the likelihood ratio test There was no stable or common k value across field sites and years for all weed species populations. The lack of stability in k across field sites is of concern, because this parameter is used extensively in the development of parametric sequential sampling procedures. Because k is not stable across field sites, k must be estimated at the time of sampling. Understanding the variability in it is critical to the development of parametric sequential sampling strategies and understanding the dynamics of weed species in the field.

An intensive survey of two farmer-managed corn and soybean fields in eastern Nebraska was conducted to investigate parametric sequential sampling of weed seedling populations using a multistage procedure to estimate k, of the negative binomial distribution. k is a nonspatial aggregation parameter related to the variance at a given mean value. Mean weed seedling density ranged from 0.18 to 3.11 plants 0.38 m−2 (linear meter of crop row) based on 806 sampling locations. The average value of k, derived from 200 multistage estimation procedures, ranged from 0.17 to 0.32. A sequential sampling plan was developed with the goal of estimating the mean with a coefficient of variation (CV) of 10, 20, 30, and 40% of the sample mean. A sampling plan was also constructed to estimate the mean within a specified distance H of the true mean (H(x̄)= 0.10, 0.50 and 1.0 plants 0.38 m−2) with 80, 85, and 90% confidence. Estimating mean weed seedling density within a specified CV of the true mean CV(x̄) using parametric sequential sampling techniques was superior to estimating the mean within a specified distance (H(x̄)) of the true mean when considering the frequency of sampling and probability of error, especially at intermediate k values. At a k: value of 0.32 and 0.25, the difference between the actual CV(x̄) obtained from sampling and the CV(x̄) specified by the sampler was minimal. However, the accuracy of weed seedling density estimates was reduced with decreasing k values below 0.25, especially as the specified CV(x̄) increased.

This article describes the collection of views from political science alumni via a web-based survey as a central part of efforts to review and improve the curriculum and the broader political science program at a public university. Based on the literature and on interviews with faculty members and former students, we iteratively constructed a questionnaire containing five categories of items: program structure, content/knowledge, skills, outcomes, and learning environment. These categories were intended to capture curricular elements and outcomes that include but extend beyond employment and professional-skill attainment. Graduate students contributed in meaningful ways to the effort through a research-methods course. The article discusses how results of the survey fed into the curriculum-revision process specifically and program review and assessment considerations more generally.

Background and Purpose:
The central and peripheral nervous systems are often affected in intensive care unit (ICU) patients, especially those with prolonged assisted ventilation and sepsis or systemic inflammatory response syndrome (SIRS). The autonomic nervous system, however, has been under-investigated in such patients. We evaluated autonomic nervous system (ANS) function in 29 ICU patients with various neurological disorders.
Methods:Testing involved cardiac R-R variation (CRRV) as an index of parasympathetic function and the sympathetic skin response (SSR) for sympathetic assessment.
Results:Only those 8 patients with sepsis-related neuropathy or encephalopathy had abnormal CRRV, while the SSR was absent in all but 2 patients.
Conclusions:Our preliminary study revealed a high incidence of autonomic dysfunction in ICU patients with various neurological disorders.

Objective
The present study assessed the impact of the 2009 food packages mandated by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on dietary intake and home food availability in low-income African-American and Hispanic parent/child dyads.
DesignA natural experiment was conducted to assess if the revised WIC food package altered dietary intake, home food availability, weight and various lifestyle measures immediately (6 months) following policy implementation.
SettingTwelve WIC clinics in Chicago, IL, USA.
SubjectsTwo hundred and seventy-three Hispanic and African-American children aged 2–3 years, enrolled in WIC, and their mothers.
ResultsSix months after the WIC food package revisions were implemented, we observed modest changes in dietary intake. Fruit consumption increased among Hispanic mothers (mean = 0·33 servings/d, P = 0·04) and low-fat dairy intake increased among Hispanic mothers (0·21 servings/d, P = 0·02), Hispanic children (0·34 servings/d, P < 0·001) and African-American children (0·24 servings/d, P = 0·02). Home food availability of low-fat dairy and whole grains also increased. Dietary changes, however, varied by racial/ethnic group. Changes in home food availability were not significantly correlated with changes in diet.
ConclusionsThe WIC food package revisions are one of the first efforts to modify the nutrition guidelines that govern foods provided in a federal food and nutrition assistance programme. It will be important to examine the longer-term impact of these changes on dietary intake and weight status.

The relics of polar exploration are treasured in the museums of a multitude of nations. In Australia, the focus of most such collections is Sir Douglas Mawson and his expeditions to Antarctica in 1911–14 and 1929–31. The nature of these collections divides into the two large categories of scientific specimens and expedition relics. The latter are spread among Australian and other museums in a distribution that speaks of fascination with the exotic and heroic aspects of the Australasian Antarctic Expedition and the geopolitical ramifications of the British, Australian and New Zealand Antarctic Research Expedition. The specimens, by contrast, have not been treated well, and although thoroughly documented, may be close to losing their integrity as scientific resources. Both types of material merit the renewed attention of their museum-keepers as resources on the history of Antarctica.

The shapes and dimensions of the statocysts of cephalopods have been measured and compared with the semi-circular canals of vertebrates. The cavities grow much more slowly than the body as a whole, but there are knobs, anticristae, which restrict the cavity, and these grow relatively faster. This ensures that the flow of endolymph across the cupulae remains small. Where the liquid is constrained within canals the radius of curvature of the whole canal, R, is similar to that of fishes, whereas its internal radius, r, is twice as large in non-buoyant and four times as large in deep-sea buoyant cephalopods as in fishes of similar size. As in fishes the restriction is greatest in the horizontal plane, providing for operation at higher frequencies in turning about the yaw axis.
The statocysts of seven species of Loligo all have similar proportions. The largest individuals of 16 genera of non-buoyant squids also have these same relative dimensions. The statocyst of Sepia is more like that of non-buoyant than of other buoyant cephalopods but yet differs significantly from that of Loligo at all sizes. On the other hand 21 genera of squids known to be neutrally buoyant are very different. Their statocysts are often larger than in the non-buoyant forms and there is less restriction of the cavity by anticristae. The greater flow of endolymph acting across the cupulae presumably provides greater sensitivity at the lower frequencies of turning of these deep-sea animals.
The data suggest that the cristae of the cephalopod statocyst may operate in the frequency band where they act as angular accelerometers whereas the vertebrate semi-circular canals operate at higher frequencies as angular velocity meters.

An interpretive qualitative study was conducted to examine public health nurses' (PHNs') practice in fostering citizen participation and collaborative practice and the impact of a decade (1992–2002) of health care restructuring. This article presents the perspectives of public health management and a public policy analysis as they relate to PHNs' primary health care practice in Nova Scotia, a province in Eastern Canada. Seven face-to-face interviews were conducted with public health management from across Nova Scotia and 26 relevant public policy documents were analyzed. Three major themes emerged from the coded transcripts and the document analysis: (1) opportunistic shifts in values: constraining structures, operations, and governance; (2) insufficient funding and infrastructure support; (3) opportunities and challenges to PHN capacity and competency. The emergent themes illustrate the unique population health perspective and day-to-day contested realities of public health and PHN practice. The study provides preliminary understanding of PHNs' primary health care practice in Nova Scotia that may resonate with other national and international settings. This knowledge can form a basis for more research to explore the PHNs' practice in the organizational context in which it is embedded. This study was undertaken at a pivotal time in Nova Scotia as the provincial government embarked on primary health care renewal to improve the health of Nova Scotians. The success of this study is in large part attributable to the collaborative effort of university researchers and public health decision makers.

Summary
ABSTRACT
The ecological fallacy that often results from ecological inference has long been a contentious issue in sociology, geography, epidemiology, and statistics. Several different solutions to the ecological inference problem have been proposed in these different disciplines. When grouped data are created by spatial aggregation, as is typically the case with Census data, the ecological inference problem can be considered as a special case of what is known in the field of geostatistics as the change-of-support problem (COSP). In this chapter, we give a brief overview of the causes of the ecological inference problem as it arises in geographical correlation studies. We relate the aggregation and specification biases resulting from the ecological fallacy to the scale and aggregation effects underlying the modifiable areal unit problem (MAUP) in geography. We introduce the COSP in spatial statistics, and show that the ecological inference problem and the MAUP, as well as the map overlay operations conducted within geographical information systems (GISs), are all special cases of the COSP. Geostatistical solutions to simple COSPs indicate a general solution strategy for these problems. We review some of these solutions and discuss some of the most recent statistical solutions to COSPs.

Amongst solid solutions of the Li-Ni-Mn-Co-O series, LiNi1/3Mn1/3Co1/3O2 has received much attention owing to its high capacity and thermal stability. A major issue in these ordered rock salt structures is the irreversibility on the first cycle, and degree of Li+/Ni2+ cation disorder which inhibits the rate capability. To examine these factors, different synthesis methods were employed which led to LiNi1/3Mn1/3Co1/3O2 that exhibited varying degrees of cation disorder. Neutron diffraction studies were carried out on samples (LixNi1/3Mn1/3Co1/3O2, x = 1.00 → 0.04) prepared by chemical oxidation. The studies reveal that the extent of Ni2+/Li+ disorder between the 3b and 3a sites was preserved on Li extraction and re-insertion. Complete extraction of lithium to form the O1 phase was achieved in some materials. However, reformation of the O3 phase on chemical relithiation does not occur in these cases, whereas materials that only partly convert to the Ol phase exhibit complete conversion back to the O3 phase on relithiation. The differences are attributed to lithium site occupancy/stoichiometry and crystallite size effects.

Being able to obtain and analyze quantitative data are an essential components of any undergraduate education in science or engineering. At the most basic level, this begins with characterizing the measurement system using proper statistical techniques. Although most undergraduates in the sciences and engineering are required to take a course in statistics, the knowledge gained in the statistics course does not always find its way into practice. In this paper we will present 4 experimental modules that will enable the student to: 1. Assess the precision of a measurement system; 2. Determine if the system is stable with respect to a number of variables; 3. Quantify the amount of variation that exists within a particular sample; 4. Quantify the amount of variation from sample to sample (i.e., process variation). Our modules were applied to the measurement of silicon dioxide thickness from an oxidation process. However, they generally apply to any process that involves measuring a physical quantity. Assessing these sources of variation in a process form the foundation for more advanced techniques such as process control and experimental design.

The recombinant human nerve growth factor (hNGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), neurotrophin 4/5 (NT4/5), and murine NGF (mNGF) dimers all undergo rapid unfolding and dissociation to monomer in GdnHCl. Fluorescence spectroscopy, reversed-phase high-performance liquid chromatography, and size-exclusion chromatography were used to show that this monomer M1 converts slowly to a more fully unfolded monomer, M2, by a first order process with half-lives of 22, 2.5, 1.6, and 0.73 h for hNGF, mNGF, NT-3, and BDNF, respectively, at 25 °C. Linear Arrhenius plots for the conversion of M1 to M2 yielded activation energies of 27, 22, 24, and 24 kcal/mol for hNGF, mNGF, NT-3, and BDNF, respectively. The refolding of these neurotrophins from 5 M GdnHCl was also first order with NT-3 the slowest to refold and BDNF the fastest. Threading of the N-terminus out through the cystine-knot loop present in each of these proteins is proposed as the slow step in unfolding. The number of amino acids in the cystine-knot loop (14 for hNGF, mNGF, NT-3, and BDNF; 21 for NT4/5), and the number and position of the proline residues in this loop (2 for hNGF; 1 for mNGF, NT-3, BDNF, and NT4/5) correlate with the relative rates of unfolding. The smaller the loop and the greater the number of prolines, the more hindered and slower the unfolding.

Summary
Introduction and overview
The Pacific Rim contains many dynamic, export-oriented economies that have grown rapidly in recent years, shifting the world's economic center of gravity toward the east. The Asia Pacific Economic Cooperation (APEC) group was established in 1989, with 12 founding members. Its goal is to promote multilateral trade reform and to facilitate regional trade. Since its inception, APEC has expanded to its present membership of 18, including: the Association of South East Asian Nations (ASEAN) of Malaysia, Thailand, Indonesia, the Philippines, Singapore, and Brunei; the “three Chinas” – China, Hong Kong, and Taiwan; South Korea; Australia; New Zealand: Papua New Guinea; the US; Canada; Mexico; and Japan. Papua New Guinea and Mexico were admitted during the APEC summit in November of 1993 and Chile was admitted in 1994. Its member economies now account for almost 50% of the world's production and 40% of world trade (Far Eastern Economic Review 1993). In November 1994 the APEC members signed the Bogor Accord, which states that they will “adopt the long-term goal of free and open trade and investment” in the region. This will be accomplished by 2010 for industrialized countries and by 2020 for developing countries (Wall Street Journal 1994). The purpose of this chapter is to analyze the implications of such an agreement for trade and welfare in the region.
An initial reason given for the creation of a free trade zone in the Pacific is disillusionment over the effectiveness of the General Agreement on Tariffs and Trade (GATT) to sustain multilateral trade liberalization.

Summary
What links the missionary generation of China sojourners to the recent crop of eager, China-bound entrepreneurs is their profound sense of disorientation when engaged in conversations with Chinese. Their disorientation has led to some interesting rhetoric and to recurring Western claims about the peculiarities of the Chinese mind. Hence the following:
There are few things more amusing, and at the same time more exasperating, to a European than the utter confusion of thought which characterizes the Chinese as a race … There seems to be a looseness of reasoning, a want of consecutiveness, in the mental process of the Chinese which argues for an internal defect in their constitution.
(Ball 1903: 166, citing Balfour, n.d.)The passage is old but its contents wear well. Despite the intervening decades, the current literature on Sino-American commercial negotiations raises similar concerns, albeit more vaguely stated. Thus, we see that a number of American companies with extensive trading experience with China continue to complain that Chinese are “indirect and like to ramble” (DePauw 1981: 52).
In this chapter, I use taped conversations to identify some inconsistencies in the surface phenomena and underlying presuppositions of talk that may go unrecognized and so jeopardize understanding between Chinese and Americans. Although my data encompass a variety of formal speech encounters, I focus primarily on a role play of a business meeting among English-speaking, Hong Kong-based Chinese managers.

Summary
Earlier chapters have delineated the conflicting expectations and cultural nuances that can enter into and affect the interactive experience between Chinese and Americans. They stressed in particular the variety of obstacles that can make smooth and satisfactory interactions between them difficult to realize. Close examination of the communicative import of culturally based discourse conventions has shown how Chinese stereotypical characteristics can take shape and become perpetuated in cross-cultural interactions. I want to pursue this theme by analyzing here two nearly identical instances of interactions between Chinese and American participants. In particular, I shall fit together the pieces of Chinese inscrutability dissected and examined in the previous chapters to give a clearcut demonstration of the evolving stages of American perceptions of Chinese inscrutability.
The strikingly different assumptions and perceptions with which Chinese and Americans often approach each other contribute to a remarkable instability in their relationship. As I have argued throughout, this instability has been accentuated by a tension created in part by the misreading of subtle cues in conversational encounters and an unfamiliarity with culturally based communicative strategies. What seem to be unproblematic and straightforward moments in their interactions are in fact troubling ambiguities which can create unanticipated misunderstandings and distortions.
When not tested for depth, instances of mismatched responses between Chinese and Americans are manageable.
