A CASE OF BIGEMINY AND SUCCESSFUL COMPLETION OF ACUTE ELECTROCONVULSIVE THERAPY COURSE

Introduction Electroconvulsive therapy (ECT) remains stigmatized in the broader medical community due to misunderstandings about treatment procedures, mortality rates, and cardiovascular complications. Several concerns have risen regarding the safety of ECT on the cardiovascular system. ECT causes periprocedural hemodynamic variability due to the surges in parasympathetic and sympathetic nervous systems following the administration of the electric current.1 Patients experience an increase in cardiac workload and oxygen demand, which is potentially dangerous for patients with preexisting heart disease. Several findings suggest the incidence of cardiac complications is relatively rare and occurs most frequently in patients with underlying cardiovascular disease. Methods We describe a case report of a 53 year old female with history of bipolar I disorder current episode depressed, hyperlipidemia undergoing ECT who developed cardiovascular complications after her seventh brief pulse right unilateral (BRUL) treatment. Electrocardiogram (EKG) monitoring revealed bigeminy for two to three minutes (heart rate in 80s) during post-anesthesia care. Results The cardiovascular system undergoes various changes during ECT including events secondary to the parasympathetic release such as asystole, hypotension, bradycardia, and events secondary to sympathetic release such as hypertension and tachycardia. Other complications include arrhythmias, ST elevation, and Takotsubo Cardiomyopathy. The patient was seen by cardiology for further work-up. EKG, 2-D cardiac echocardiogram, 48-hour Holter monitoring, and coronary CT calcium scan were performed. She was found to have rare premature atrial contractions (PACs) (8 in 48 hours). Her bigeminy resolved spontaneously. The patient was able to complete the acute course of BRUL ECT and continued onto maintenance ECT with good effect. We also present a table with the common cardiovascular side effects from ECT and the most recent evidence-based treatment strategies to manage them. Conclusions Generally, ECT is a safe procedure; complications are minor and manageable. Most major complications caused by ECT are related to the cardiovascular system; however, with an appropriate pre-ECT evaluation and a comprehensive multidisciplinary-team approach the cardiovascular complications can be well managed and minimized. Our case highlights the benefits of a multidisciplinary care model between psychiatry, anesthesia, and cardiology. Providing proper cardiac clearance can prevent cardiac complications and provide timely care to treatment-resistant populations who are at risk for excessive morbidity and suicide.

Structural basis of specific DNA binding by the transcription factor ZBTB24

ZBTB24, encoding a protein of the ZBTB family of transcriptional regulators, is one of four known genes-the other three being DNMT3B, CDCA7 and HELLS-that are mutated in immunodeficiency, centromeric instability and facial anomalies (ICF) syndrome, a genetic disorder characterized by DNA hypomethylation and antibody deficiency. The molecular mechanisms by which ZBTB24 regulates gene expression and the biological functions of ZBTB24 are poorly understood. Here, we identified a 12-bp consensus sequence [CT(G/T)CCAGGACCT] occupied by ZBTB24 in the mouse genome. The sequence is present at multiple loci, including the Cdca7 promoter region, and ZBTB24 binding is mostly associated with gene activation. Crystallography and DNA-binding data revealed that the last four of the eight zinc fingers (ZFs) (i.e. ZF5-8) in ZBTB24 confer specificity of DNA binding. Two ICF missense mutations have been identified in the ZBTB24 ZF domain, which alter zinc-binding cysteine residues. We demonstrated that the corresponding C382Y and C407G mutations in mouse ZBTB24 abolish specific DNA binding and fail to induce Cdca7 expression. Our analyses indicate and suggest a structural basis for the sequence specific recognition by a transcription factor centrally important for the pathogenesis of ICF syndrome.
Examining the Use of Auditory Signals as “Attention-Getters” in Zoo-Housed Gorillas ( Gorilla gorilla gorilla ) and Orangutans ( Pongo pygmaeus and Hybrid)

“Attention-getters” are proposed to be gestures that function to attract the attention of a recipient and therefore allow further communication to take place. Their use is an indicator of intentional communication and thus of great interest to researchers in the field of language evolution. However, there is conflicting evidence as to whether nonhuman primates use attention-getters, both in conspecific interactions and in interactions with humans. We examined whether zoo-housed orangutans (Pongo pygmaeus and hybrid [Pongo pygmaeus × Pongo abelii]) and gorillas (Gorilla gorilla gorilla) used auditory signals to initiate visual communication with a human. To test this, a human experimenter stood with food in her hand and her back to the ape. If the ape produced an auditory signal, the experimenter either turned to face the ape or, in the control condition, away from the ape. We found that condition had no significant effect on whether the apes followed their initial auditory signal with a visual signal. Furthermore, the apes did not show greater persistence with, or elaboration of, their auditory signals when the human did not turn to face them, than when she did. In contrast, the apes showed significantly more persistence and elaboration of visual signals when the experimenter turned to face them. Our results suggest that while the orangutans and gorillas were able to discriminate human visual attention and use visual gestures accordingly, they did not attempt to manipulate this attention through the use of auditory behaviors to initiate visual communication.
Comparison of Time Series Methods and Machine Learning Algorithms for Forecasting Taiwan Blood Services Foundation's Blood Supply.

Purpose. The uncertainty in supply and the short shelf life of blood products have led to a substantial outdating of the collected donor blood. On the other hand, hospitals and blood centers experience severe blood shortage due to the very limited donor population. Therefore, the necessity to forecast the blood supply to minimize outdating as well as shortage is obvious. This study aims to efficiently forecast the supply of blood components at blood centers. Methods. Two different types of forecasting techniques, time series and machine learning algorithms, are developed and the best performing method for the given case study is determined. Under the time series, we consider the Autoregressive (AUTOREG), Autoregressive Moving Average (ARMA), Autoregressive Integrated Moving Average (ARIMA), Seasonal ARIMA, Seasonal Exponential Smoothing Method (ESM), and Holt-Winters models. Artificial neural network (ANN) and multiple regression are considered under the machine learning algorithms. Results. We leverage five years worth of historical blood supply data from the Taiwan Blood Services Foundation (TBSF) to conduct our study. On comparing the different techniques, we found that time series forecasting methods yield better results than machine learning algorithms. More specifically, the least value of the error measures is observed in seasonal ESM and ARIMA models. Conclusions. The models developed can act as a decision support system to administrators and pathologists at blood banks, blood donation centers, and hospitals to determine their inventory policy based on the estimated future blood supply. The forecasting models developed in this study can help healthcare managers to manage blood inventory control more efficiently, thus reducing blood shortage and blood wastage.
Crystal structures of two solvated 2-aryl-3-phenyl-2,3-di-hydro-4H-pyrido[3,2-e][1,3]thia-zin-4-ones.

The synthesis and crystal structures of 2-(4-fluoro­phen­yl)-3-phenyl-2,3-di­hydro-4H-pyrido[3,2-e][1,3]thia­zin-4-one toluene hemisolvate (1), C19H13FN2OS·0.5C7H8, and 2-(4-nitro­phen­yl)-3-phenyl-2,3-di­hydro-4H-pyrido[3,2-e][1,3]thia­zin-4-one iso­propanol 0.25-solvate 0.0625-hydrate (2), C19H13N3O3S·0.25C3H7O·0.0625H2O, are reported. Both are racemic mixtures (centrosymmetric crystal structures) of the individual com­pounds and incorporate solvent mol­ecules in their structures. Compound 2 has four thia­zine mol­ecules in the asymmetric unit. All the thia­zine rings in this study show an envelope pucker, with the C atom bearing the substituted phenyl ring displaced from the other atoms. The phenyl and aryl rings in each of the mol­ecules are roughly orthogonal to each other, with dihedral angles of about 75°. The extended structures of 1 and 2 are consolidated by C—H⋯O and C—H⋯N(π), as well as T-type (C—H⋯π) inter­actions. Parallel aromatic ring inter­actions (π–π stacking) are observed only in 2.

Fall-Winter Grazing After Fire in Annual Grass-Invaded Sagebrush Steppe Reduced Annuals and Increased a Native Bunchgrass

Abstract Exotic annual grass invasion and dominance of rangelands is a concern across western North America and other semiarid and arid ecosystems around the world. Postfire invasion and dominance by exotic annual grasses in sagebrush communities is especially problematic as there are no cost-effective control strategies available for the vast acreages already invaded. However, fall-winter grazing by cattle has been suggested as a potential tool to decrease exotic annual grasses and encourage native perennial vegetation, but to date its efficacy has not been tested. We evaluated fall-winter grazing over 4 yr after wildfire in Wyoming big sagebrush (Artemisia tridentata Nutt. subsp. wyomingensis Beetle & Young) steppe invaded by exotic annual grasses. Fall-winter grazing reduced exotic annual grass and annual forb cover and density and increased the native perennial bunchgrass, Sandberg bluegrass (Poa secunda L.). Exotic annual grass cover and density were 1.5 × greater in ungrazed compared with fall-winter grazed areas after 4 yr. At this time, Sandberg bluegrass density and cover were 1.6 × and 2.3 × greater in fall-winter grazed compared with ungrazed areas. Large perennial bunchgrasses and perennial forbs did not increase with fall-winter grazing because either grazing did not facilitate their increase or they were slow to respond to decreases in exotic annuals. Fall-winter grazing likely decreased exotic annual grass by defoliating it during its early growth in the fall and late winter and by reducing ground cover that facilitates exotic annual grass emergence and growth. Fall-winter grazing clearly reduced exotic annual grasses, but its effects on native perennial vegetation were not conclusive. Careful application of fall-winter grazing appears to be a valuable tool for managing exotic annual grass cover and abundance, but longer-term research is necessary to determine if it can facilitate the return of native perennial dominance.
Magnetic field imaging in a laboratory plasma

In laboratory plasmas, arrays of probes have typically been used to measure the evolution of the magnetic field topology. Here, we present initial image-based measurements of the magnetic topology in a low-temperature plasma using a purely optical diagnostic. Laser induced fluorescence measurements of neutral velocity distribution functions are made using a fast camera, imaging the Zeeman splitting of σ-peaks in neutral argon. The separation of σ-peaks provides spatially resolved magnetic field magnitude measurements with a detection threshold on the order of 10 G.

Efficient communication strategies for distributed signal field estimation

Wireless sensor networks are a promising architecture for monitoring large spatial areas. While recent years have seen a surge of research activity in sensor networks, many significant challenges need to be overcome to realize the vision of sensor networks. The key challenges are tied to two vital operations in a sensor network: efficient information routing between sensor nodes to extract useful information from the data collected by the sensors; and efficient communication of this information from the network to a certain destination. This paper proposes a novel collaborative communication and estimation scheme for distributed signal field estimation that overcomes these challenges by exploiting the underlying smoothness of the field. In our approach, the signal field is uniformly partitioned into multiple regions and the nodes in each region coherently communicate their measurements via a dedicated noisy multiple access channel (MAC) to the destination where the estimate of each region is constructed to give an estimate of the entire field. Two salient features of our scheme are: it requires relatively little collaboration among sensing nodes; and is potentially far more power-efficient due to the power pooling gain afforded by coherent cooperation of the nodes in each region. In this paper, we analyze our new approach under the simple setting of estimating a piece-wise constant field and show that optimal mean-square distortion scaling can be achieved at the destination with constant network power (vanishing per node power).
Evaluation of Soybean Varieties in the Northern Uniform Soybean Test–Uniform Test III

The Northern Uniform Soybean Test is used to evaluate soybean varieties produced by several public breeding programs in the northern portion of the United States and Canada. In 2010, five public breeding programs participated in the Northern Uniform Soybean Test (Uniform Test I). Public breeders are allowed to enter varieties into the Uniform Test in exchange for growing locations for the test. Material entered into the Uniform Test is generally in advanced stages of a breeding program. The Uniform Soybean Test is an efficient method for soybean breeders to get multiple location data, in a very efficient manner in comparison to each individual program growing their own locations. It also produces useful information by comparing soybean lines from multiple programs, and identifies lines from other states that produce well in northern Iowa. Results from these tests are used by breeders to select varieties with superior yield and/or disease resistance to continue advancement on a trek toward variety release. These results are also used to demonstrate positive characteristics to growers and other interested parties.
Involvement of NFAT1 in B Cell Self-Tolerance

B cells from anti-lysozyme Ig/soluble lysozyme double-transgenic mice are chronically exposed to self-Ag in the periphery, resulting in an anergic phenotype. Chronic exposure to self-Ag leads to nuclear translocation of NFAT1 and NFAT2, suggesting that they are involved in anergy. To directly test a role for NFAT1 in B cell anergy, NFAT1-deficient mice were crossed with anti-lysozyme Ig transgenic mice. As expected, B cell anergy was evident in the presence of self-Ag based on reduced serum anti-lysozyme levels, percentage and number of mature B cells, and reduced B cell responsiveness. By contrast, B cell anergy was relieved in NFAT1−/− mice expressing soluble self-Ag. Bone marrow development was equivalent in NFAT1-sufficient and -deficient mice, suggesting that loss of anergy in the latter is due to selection later in development. Taken together, these studies provide direct evidence that the transcription factor NFAT1 is involved in B cell anergy.
The anomalous ionosphere between solar cycles 23 and 24

[1] The solar minimum period during 2008–2009 was characterized by lower thermospheric density than the previous solar minimum and lower than any previously measured. Recent work used the NCAR Thermosphere-Ionosphere-Electrodynamics General Circulation Model to show that the primary cause of density changes from 1996 to 2008 was a small reduction in solar extreme ultraviolet (EUV) irradiance, causing a decrease in thermospheric temperature and hence a contracted thermosphere. There are similar effects in the ionosphere, with most measurements showing an F region ionosphere that is unusually low in density, and in peak altitude. This paper addresses the question of whether model simulations previously conducted, and their solar, geomagnetic, and anthropogenic inputs, produce ionospheric changes commensurate with observations. We conducted a 15 year model run and obtained good agreement with observations of the global mean thermospheric density at 400 km throughout the solar cycle, with a reduction of ~30% from the 1996 solar minimum to 2008–2009. We then compared ionosonde measurements of the midday peak density of the ionospheric F region (NmF2) to the model simulations at various locations. Reasonable agreement was obtained between measurements and the model, supporting the validity of the neutral density comparisons. The global average NmF2 was estimated to have declined between the two solar minima by ~15%. In these simulations, a 10% reduction of solar EUV plays the largest role in causing the ionospheric change, with a minor contribution from lower geomagnetic activity and a very small additional effect from anthropogenic increase in CO2.
ADiEU: Toward Domain-Based Evaluation of Spoken Dialog Systems

We propose a new approach toward evaluation of spoken dialog systems. The novelty of our method is based on utilization of domain-specific knowledge combined with the deterministic measurement of dialog system performance on a set of individual tasks within the domain. The proposed methodology thus attempts to answer questions such as: "How well is my dialog system performing on a specific domain?", "How much has my dialog system improved since the previous version?", "How much is my dialog system better/worse than other dialog systems performing on that domain?"
Scientology: To Be Perfectly Clear

Scientology, one of the largest and most influential cults, claims to have raised over sixteen thousand members up to a superhuman level of mentalfunctioning known as "clear." This paper presents a theory of how the cult can appear to have succeeded in accomplishing this task. We argue that clear has been transformedfrom a postulated objective state of being into a wellbuttressed social status in the highly stratified social structure of the cult. Four strategies invented by thefounder of Scientology encourage members to play the role associated with the clear status: (1) prohibition of indpendent creation and evaluation of clears, (2) development ofa hierarchy of statuses below clear, (3) isolation ofthe preclear at the crucial stage in upward progress, (4) development of a hierarchy of statuses above clear. The Scientology processes supposedly able to make people clear are examples of modern magic -mental and symbolic exercises undertaken to accomplish the impossible -and therefore are highly subject to empirical disconfirmation. Despite the momemtary success of the cult's strategies to protect its magic, we suggest that Scientology may be forced to evolve more fully into a true religion that promises supernatural rewards which only can be obtained in a world beyond the senses.
Increased chest compression to ventilation ratio improves delivery of CPR

Summary Objective Chest compressions are interrupted during cardiopulmonary resuscitation (CPR) due to human error, for ventilation, for rhythm analysis and for rescue shocks. Earlier data suggest that the recommended 15:2 compression to ventilation ( C : V ) ratio results in frequent interruptions of compressions during CPR. We evaluated a protocol change from the recommended C : V ratio of 15:2–30:2 during CPR in our municipal emergency medical system. Methods Municipal firefighters ( N = 875) from a single city received didactic and practical training emphasizing the importance of continuous chest compressions and recommending a 30:2 C : V ratio. Both before and after the training, digital ECG and voice records from all first-responder cases of out-of-hospital cardiac arrest were examined off-line to quantify chest compressions. The number of chest compressions delivered and the number and duration of pauses in chest compressions were compared by t -test for the first three 1 min intervals when CPR was recommended. Results More compressions were delivered during minutes 1, 2, and 3 during CPR with the 30:2 C : V ratio (78 ± 29, 80 ± 30, 74 ± 26) than with the 15:2 C : V ratio (53 ± 24, 57 ± 24, 51 ± 26) ( p C : V ratio (1.7 ± 1.2, 2.2 ± 1.2, 1.8 ± 1.0) than with the 15:2 C : V ratio (3.4 ± 2.6, 4.7 ± 7.2, 4.0 ± 2.9) ( p ≤ 0.01). Degradation of the final ECG to asystole occurred less frequently after the protocol change (asystole pre 67.1%, post 56.8%, p Conclusions Retraining first responders to use a C : V ratio of 30:2 instead of the traditional 15:2 during out-of-hospital cardiac arrest increased the number of compressions delivered per minute and decreased the number of pauses for ventilation. These data are new as they produced persistent and quantifiable changes in practitioner behavior during actual resuscitations.
The self-domestication hypothesis: evolution of bonobo psychology is due to selection against aggression

Experiments indicate that selection against aggression in mammals can have multiple effects on their morphology, physiology, behaviour and psychology, and that these results resemble a syndrome of changes observed in domestic animals. We hypothesize that selection against aggression in some wild species can operate in a similar way. Here we consider the bonobo, Pan paniscus, as a candidate for having experienced this ‘self-domestication’ process. We first detail the changes typically seen in domesticated species including shifts in development. We then show that bonobos show less severe forms of aggression than chimpanzees, Pan troglodytes, and suggest that this difference evolved because of relaxed feeding competition. We next review evidence that phenotypic differences in morphology and behaviour between bonobos and chimpanzees are analogous to differences between domesticates and their wild ancestors. We then synthesize the first set of a priori experimental tests of the self-domestication hypothesis comparing the psychology of bonobos and chimpanzees. Again, bonobo traits echo those of domesticates, including juvenilized patterns of development. We conclude that the self-domestication hypothesis provides a plausible account of the origin of numerous differences between bonobos and chimpanzees, and note that many of these appear to have arisen as incidental by-products rather than adaptations. These results raise the possibility that self-domestication has been a widespread process in mammalian evolution, and suggest the need for research into the regulatory genes responsible for shifts in developmental trajectories in species that have undergone selection against aggression.
POLITICAL MOBILIZATION AND VOTER TURNOUT IN THE 1990 MIDTERM ELECTIONS: AN AGGREGATE-LEVEL ANALYSIS

In the following analysis, we utilize district level data on voter turnout to examine the relationship between political mobilization and voter turnout. The analysis improves on previous research in the following three ways: (1) we incorporate a dynamic element into our analysis allowing us to examine differences in turnout across election years; (2) we more closely examine the nonrecursive relationship between the closeness of an election and fluctuations in voter turnout; and (3) we relate our findings to the question of whether or not turnout makes a difference in electoral outcomes. The results indicate that while demographic factors help to explain the level of turnout across congressional districts, differences in turnout across election years are better explained as a function of campaign mobilization and residential mobility. In addition, by taking into account the simultaneity between electoral competitiveness and turnout, we find that turnout is not only stimulated by more competitive elections, but that turnout contributes to electoral competitiveness.
CHEMOPATHOLOGICAL STUDIES WITH COMPOUNDS OF ARSENIC III. ON THE PATHOLOGICAL ACTION OF ARSENICALS ON THE ADRENALS.

1. Toxic doses of all arsenicals of which we have any knowledge produce definite pathological changes in the adrenals of guinea pigs. These changes include congestion, hemorrhage, disturbances in the lipoid content, cellular degenerations and necroses, and reduction in the chromaffin content. 2. The character and severity of the injury produced by different arsenicals varies with the chemical constitution of the compounds. 3. From these facts, we believe that adrenal injury is an important factor in arsenical intoxication and suggest that therapeutic doses of some arsenicals may produce adrenal stimulation.
Pharmacokinetic Considerations of Oral Chemotherapy in Elderly Patients with Cancer

Persons over the age of 65 years are the fastest growing segment of the US population. In the next 30 years they will comprise over 20% of the population. Fifty per cent of all cancers occur in this age group and therefore there will be an expected rise in the total cancer burden. There has been an increasing trend over the past 20 years toward the use of oral chemotherapy. This change has been encouraged by the need to decrease the costs of chemotherapy administration, patient preferences and quality of life issues. Factors that must be considered with oral chemotherapy administration include limitations of saturability of absorption, patient compliance and pharmacokinetic/pharmacodynamic changes which occur in elderly patients. Interpatient variability and drug metabolism, particularly age-related changes in drug metabolism are being studied. The cytochrome P450 system has been intensively studied because of its importance with regard to chemotherapeutic drugs. This article reviews these issues and provides details regarding specific drugs including temozolomide, thalidomide, topotecan, the fluoropyrimidines, etoposide, hydroxycarbamide (hydroxyurea), tamoxifen, and alkylating drugs. Complementary and alternative therapies are also discussed.
Electron transport system in Ascaris lumbricoides.

Abstract Activities of cytochrome oxidase, diaphorase, DPNH and TPNH cytochrome reductase, succinic cytochrome c reductase were demonstrated in a particulate preparation of the Ascaris muscle. This would suggest the presence of an electron transport system through the cytochrome system. The activity of DPNH or TPNH cytochrome c reductase was not inhibited by Antimycin A, but the reduction of cytochrome c by succinic acid was completely inhibited by Antimycin A. Evidence has been presented for the presence of an alternate pathway for the oxidation of DPNH and succinic acid by molecular oxygen. This pathway is insensitive to cyanide and Antimycin A and this terminal oxidation appears to be mediated by a cytochrome b component. The latter was demonstrated by spectrophotometric methods. A tentative scheme of the pathways of electron transport in Ascaris muscle is presented.
Radial Distribution Functions In Liquids And Fractal Aggregates

Abstract This article describes the current understanding of molecular arrangements in the liquid state and how they can be related to fractal aggregates. A simple model of cluster fractal geometry is found an approximation to the real fluid. More complex approaches using the multifractal function and experimental measurements are more practical for the study of fractal aggregates in liquid. The critical state is a special example where the fractal behavior is shown through the critical exponents.
Vibrational energy relaxation of a hydrogen-bonded complex dissolved in a polar liquid via the mixed quantum-classical Liouville method.

The vibrational energy relaxation (VER) of the hydrogen stretch in a linear hydrogen-bonded complex dissolved in a polar solvent is studied. The study is based on the Azzouz−Borgis model [Azzouz, H.; Borgis, D. J. Chem. Phys. 1993, 98, 7361], which is known to account for many important features of real hydrogen-bonded systems, including ionic-to-covalent tautomerism and a broad distribution of hydrogen stretch frequencies. A description of VER in this strongly coupled system is considered, which consists of the following three consecutive steps: (1) solvation on the adiabatic excited vibrational surface; (2) nonadiabatic transition from the excited to the ground adiabatic vibrational surface; and (3) solvation on the adiabatic ground vibrational surface. The relaxation dynamics during those three steps were simulated via the mixed quantum−classical Liouville method, where the hydrogen is treated quantum-mechanically, while the other particles are treated in a classical-like manner. The solvation on the ...
Is your resNet support boat sinking?: try outsourcing!

Skidmore is a small liberal arts College with 1,800 residential students. Nearly every student has their own computer and some have more than one, so support is becoming an ever increasing challenge. With viruses, worms and spyware running rampant in the residence halls, the support burden on the help desk was increasing significantly every semester. The help desk has one full time employee (the coordinator) and nineteen student assistants. Add to this an aging infrastructure and the cost of adding packet shaping, firewalls, computer registration systems and intrusion detection, and you can see that the costs of support, both in time and hardware, was bringing us to our knees. As part of a report to the College Administration about the state of the infrastructure several alternatives were explored. One of these alternatives was outsourcing the entire student network. This paper will explore this alternative beginning with the existing support models and infrastructure. We will show the planned changes and then discuss the reality.
Treatment of the psychotic pregnant patient

Abstract Psychiatric inpatient treatment is often required to help the psychotic pregnant patient with the multitude of problems with which she must contend. Schizophrenic women often experience an intensification of delusional ideas seemingly related to the bodily changes and fetal movement in pregnancy. Women with bipolar affective disorders often respond well to the tasks of carrying and delivering the baby, but are prone to worsening of psychotic symptoms or depression in the postnatal period. The authors examine psychodynamic issues, medication management problems, and legal and ethical aspects in the treatment of these patients.
Estimation of wave vector characteristics

Abstract In the realistic case of multiple electromagnetic plasma wave sources and multiple propagation paths, auto-correlation and cross-correlation products of the six wave components can be utilized to fit model parameters for the wave normal vector and Poynting vector distribution functions. With the complete wave vector characteristics, the wave mode can be identified, the index of refraction derived and the wave ray traced back towards the wave source region. Plasma wave instrumentation suitable for estimating some wave vector characteristics has been carried on satellites starting with FR-1 in 1964 and has evolved in various configurations on OGO-5, Injun-5, GEOS, Voyager, ISEE, Dynamics Explorer and the proposed OPEN spacecraft. Plasma wave research needs to advance along two parallel lines: (a) developing more sophisticated computer techniques for extracting the wave vector information from extensive data sets and (b) utilizing microprocessor technology in flight instruments to recognize specified phenomena and to capture the appropriate wave data for further on-board or ground processing.
Living a private life in public social networks: An exploration of member self-disclosure

Abstract In this article, the author examines voluntary self-disclosure phenomenon among social networking sites. Self-disclosure enables member interactions, service customizations, targeted marketing, and digital content generation; hence the level of self-disclosure is imperative to the success of social networking sites. Yet, members are often reluctant to reveal themselves despite their desire for socialization in the ever-increasingly popular cyber community. Drawing upon relevant literature, we developed a succinct research model that identifies key stimuli and inhibitors of member self-disclosure. These influences stem from personality traits (e.g., extroversion and privacy value), networking service attributes (e.g., perceived critical mass), and computing environments (e.g., perceived Internet risk). The research model was validated through survey data collected from 222 social networking site users and the analysis results provided support to the hypothesized relationships. The current study generates new knowledge concerning the roles that varying factors play in shaping members' self-disclosure; it also informs networking service providers about how to better encourage members to reveal themselves online.
Pyrrolopyrimidine nucleosides. XIII. Synthesis and chemical reactivity of certain selenopyrrolo[2,3-d]pyrimidine nucleosides†

5-Cyano-7-(β-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidin-4-selone (1) has been prepared via a reaction of the appropriate 4-chloro compound with sodium hydrogen selenide. Alkylation of 2 under basic conditions has provided certain 4-substitutedseleno-5-cyano-7-(β-D-ribofuranosyl)-pyrrolo[2,3-d]pyrimidines. 5-Cyano-4-methylseleno-7-(β-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine was allowed to react with hydroxylamine and hydrazine. The products obtained and reaction course were compared to those obtained from identical reactions using the corresponding sulfur analog.
Instruction Via Web-Based Modules in Early Childhood Personnel Preparation: A Mixed-Methods Study of Effectiveness and Learner Perspectives

Effective personnel preparation is critical to the development of a high quality early childhood workforce that provides optimal care and education for young children. This mixed-methods study examined the effectiveness of, and learner perspectives on, instruction via web-based modules within face-to-face early childhood personnel preparation courses. The specific modules selected were designed around an evidence-based decision-making framework and focused on evidence-based practices: embedded interventions, assistive technology, and tiered instruction. Nineteen undergraduate students studying early childhood participated in pre- and post-instruction surveys and post-instruction focus groups. Participants’ written module activities provided additional sources of data. Statistical analyses of quantitative survey data and thematic analyses of qualitative survey data and focus groups were conducted. Results found the web-based modules to be effective, as indicated by learners’ knowledge and competence ratings, written explanations of the specific evidence-based practices, and completed assignments. Examination of learner perspectives indicated that learners perceived web-based modules to be effective over and above other instructional methods and preferred web-based modules to traditional instruction, at least to some degree. Learners found videos and realistic practice dilemmas to be the most useful module resources. They reported technology challenges and identified preferred supports, including more in-class discussion. Implications for personnel preparation and further research are discussed.
An Analysis of Women Urban Superintendents A National Study

This is a study of the descriptors of the work lives of women superintendents in urban areas. The variables of interest were perceived sources of job satisfaction, personal benefits of the job, self-fulfillment, and personal strengths that they bring to the job. The study indicates that women urban superintendents use collegial approaches in highly bureaucratic/structured systems.
SW 2 - An object-based programming environment

Programming systems traditionally deal with only a few different types of data objects. Operating-system command languages, for example, are concerned with files and programs. Typical programming languages deal with computer-related objects such as integers, strings, arrays, and records. This is in sharp contrast to the variety of real-world objects that people reason about. Smallworld is a programming environment in which the real world is represented by objects that have properties. A property represents a fact about the corresponding real-world entity. Thus Smallworld actions (programs), which operate on objects specified in this simple but general way, are “smart”: they consider all of the relevant facts concerning (that is, all of the properties of) the objects they manipulate. Smallworld was strongly influenced by the design of Smalltalk, especially in the organization of objects into classes and superclasses. The two languages differ (1) in their treatment of the difference between classes and objects that are not classes and (2) in their definition of methods that act on classes. Smallworld minimizes the differences between classes and non-class objects, resulting in a simpler and more consistent system. Where Smalltalk is a programming language using a pure object-oriented paradigm and dependent on a powerful graphical interface, Smallworld is a shell language that runs on conventional terminals and allows multiple program paradigms where appropriate.

In this paper the field of electrical engineering education in the People's Republic of China (PRC) will be discussed in three parts: 1) the evolution of technical universities from 1949 to the present; 2) the organization, instructional method, and research; and 3) examples of areas of specialization and curriculum.
Detection of signals modeled by interaction point processes using a Poisson approximation

The performance of the likelihood ratio test is considered for point processes with piecewise constant interaction functions, and point processes featuring a reduced number of isolated-points. A Poisson approximation of the sufficient statistics is used to evaluate the performance. The approximations are compared with empirical results generated using Markov chain Monte Carlo simulation.
Mucocutaneous Manifestations in Children with HIV Infection and AIDS

Mucocutaneous diseases are more frequent in HIV/AIDS-infected children than in the normal population. We analyze mucocutaneous disorders with atypical presentations in a large population of HIV-infected children, with or without full-blown AIDS, compared to a population of HIV seroreverted children. The majority of these cutaneous disorders have an infectious etiology and their frequency is related to the degree of deterioration of the immune system. Some diseases commonly observed in adults are rare in children; neoplasms are an exception.
Cyclic adenosine monophosphate modulates cell morphology and behavior of a cultured renal epithelial

The role of cyclic adenosine monophosphate (cAMP) dependent protein kinase (PKA) in modulating functions of differentiated renal cells is well established. Its importance in controlling their growth and differentiation is less clear. We have used somatic cell genetic techniques to probe the role of PKA in controlling morphology and behavior of a renal epithelial cell line, LLC-PK1, which acquires many properties characteristic of the renal proximal tubular cell. Mutants of this line altered in PKA activity have been isolated and their behavior compared to that of the parent line. The results indicate that PKA is involved, either directly or indirectly, in maintenance of cell morphology, cell-cell and cell-substratum interactions, density-dependent growth regulation, and expression of one function characteristic of the renal proximal tubular cell, Na-hexose symport. The relevance of these results to the role of PKA in controlling growth and differentiation of renal epithelial cells in vivo is discussed.
Photoelectron spectroscopy of surfaces under humid conditions

Abstract The interaction of water with surfaces plays a major role in many processes in the environment, atmosphere and technology. Weathering of rocks, adhesion between surfaces, and ionic conductance along surfaces are among many phenomena that are governed by the adsorption of molecularly thin water layers under ambient humidities. The properties of these thin water films, in particular their thickness, structure and hydrogen-bonding to the substrate as well as within the water film are up to now not very well understood. Ambient pressure photoelectron spectroscopy (APXPS) is a promising technique for the investigation of the properties of thin water films. In this article we will discuss the basics of APXPS as well as the particular challenges that are posed by investigations in water vapor at Torr pressures. We will also show examples of the application of APXPS to the study of water films on metals and oxides.
Photochemical synthesis of new (η6-arene)Cr–hydrido stannyl and (η6-arene)Cr–bis-stannyl complexes. Ligand effects on the Sn–H interaction in the hydrido stannyl compounds

Abstract Hydrido stannyl compounds containing the η2-H–SnPh3 ligand and bis-stannyl compounds containing two SnPh3 ligands have been obtained from the photolysis of (η6-arene)Cr(CO)3 and HSnPh3. New complexes with different arenes (mesitylene, trifluorotoluene and 1,4-dimethoxybenzene) have been obtained and characterized by X-ray diffraction: (η6-C6H4(OCH3)2)Cr(CO)2(HSnPh3) (3a), (η6-C6H4(OCH3)2)Cr(CO)2(SnPh3)2 (3b). Structural data for 3a: monoclinic; space group P21/c (No. 14); a=17.445(3), b=9.820(3) and c=16.302(5) A; Z=4; V=2539.2(12) A3; 3b: monoclinic; space group P21/n (No. 14); a=13.904(3), b=20.567(5) and c=13.911(3) A; Z=4; V=3994(2) A3. 1H-NMR as well as X-ray provided evidence for the existence of three-center two-electron bonds in the hydrido stannyl complexes. The effects of different ligands on bonding and spectroscopic parameters were studied. Arene exchange reactions of the bis-stannyl complexes, as well as reactions of some of these compounds with P(C2H5)3 and CO, were also investigated.

Nanosphere Lithography: Surface Plasmon Resonance Spectrum of a Periodic Array of Silver Nanoparticles by Ultraviolet−Visible Extinction Spectroscopy and Electrodynamic Modeling

In this paper we measure the optical extinction spectrum of a periodic array of silver nanoparticles fabricated by nanosphere lithography (NSL) and present detailed comparisons of the results with predictions of electrodynamic theory. The silver nanoparticles are small (∼100 nm) compared to the wavelength of light but too large to have their optical properties described adequately with a simple electrostatic model. We make use of the discrete dipole approximation (DDA), which is a coupled finite element method. With the DDA one can calculate the extinction of light as a function of wavelength for particles of arbitrary size and shape. We show that NSL-fabricated Ag nanoparticles can be modeled without adjustable parameters as truncated tetrahedrons, taking their size and shape parameters directly from atomic force microscopy (AFM) measurements and using literature values of the bulk dielectric constants of silver. These AFM measurements are presented as part of this paper, and the resulting theoretical li...
Discovering authorities in question answer communities by using link analysis

Question-Answer portals such as Naver and Yahoo! Answers are quickly becoming rich sources of knowledge on many topics which are not well served by general web search engines. Unfortunately, the quality of the submitted answers is uneven, ranging from excellent detailed answers to snappy and insulting remarks or even advertisements for commercial content. Furthermore, user feedback for many topics is sparse, and can be insufficient to reliably identify good answers from the bad ones. Hence, estimating the authority of users is a crucial task for this emerging domain, with potential applications to answer ranking, spam detection, and incentive mechanism design. We present an analysis of the link structure of a general-purpose question answering community to discover authoritative users, and promising experimental results over a dataset of more than 3 million answers from a popular community QA site. We also describe structural differences between question topics that correlate with the success of link analysis for authority discovery.
Examining the role of face work in a workplace complaint narrative

In recent years, interest in examining the diverse functions and features of oral narratives told in workplace contexts has grown alongside the body of research investigating the role of language in enacting politeness in the workplace. Yet, to date, there has been little integration of these two strands of inquiry. This paper forges a link between linguistic politeness and some social functions of institutional narratives. Specifically, the micro-analysis of one narrative taken from a corpus of teacher/supervisor feedback sessions demonstrates how the narrator, a novice teacher, negotiates the telling of a complaint narrative to her supervisor along with the politeness demands embedded in the local context of telling. I argue that the speaker’s contradictory evaluation of her situation interacts with linguistic politeness (i.e., the need to mitigate a “face-threatening act”) in the situated telling of this narrative. Finally, in the spirit of recent work on narrative, which calls for increased attention to context in narrative activities, this paper highlights the importance of considering the interrelationships among factors such as face work, recipient design, production circumstances, and institutional roles and relationships among speakers, in the analysis of institutional narratives.
Magnetic bubble-domain detection: Review and outlook

This paper reviews the early work on the detection of magnetic bubble domains, as well as summarizing and comparing the most recent results. Topics include InSb sensors, Permalloy sensors (thick-film as well as thin-film), and bubble stretching techniques. The limitations on sensor input power imposed by heat dissipation and other factors are discussed. The relationship between bubble size and sense signal is then examined. Finally, projections are made for the detection of submicron bubble domains.
Grades, Attendance, and Extraversion.

Extraversion correlated —.15 with both grades and class attendance of 216 introductory psychology students. These findings were hypothesized and are congruent with Eysenck's theory of personality. Otis scores also correlated — .23 with extraversion. This correlation contrasts with no relationship between intelligence and extraversion usually reported. The discrepancy seems related to the type of intelligence test employed.
The phase diagram of a U(1) Higgs-Yukawa model at finite λ

Abstract In this paper we investigate how the phase diagram of a U(1) symmetry Higgs-Yukawa system depends on the scalar self-coupling λ. The phase diagram of similar models with continuous symmetry were extensively studied in the infinite scalar self-coupling λ = ∞ limit. Recent analytical and numerical calculations at zero self-coupling showed qualitatively different phase diagram, raising the question of the λ-dependence of the phase diagram. Here we use analytical (large- N f , perturbative and mean-field) approximations as well as numerical simulations to investigate the system.
