Design of a digital mathematical library for science, technology and education

The concept of a digital library is of proven worth because of its ability to provide dramatic capabilities that are impossible with traditional print media. We are interested in providing such capabilities for scientific, technical and educational users of mathematical reference data. Our attention is focused on the highly specialized field of mathematics that is concerned with the properties, application and computation of the elementary and higher mathematical functions. Calling upon domain experts worldwide for assistance, the National Institute of Standards and Technology is conducting an ambitious project to construct, ab initio, a comprehensive and authoritative Web resource on this subject. The need to make effective use of the latest developments in digital library research is a major focus, as is the development of content. We discuss our approach to such difficulties as the representation, display and manipulation of symbolic expressions, numerical data and graphical visualizations, and we describe a prototype Web site that has been constructed to test, evaluate and advance the NIST Digital Library of Mathematical Functions project.
Reconfigurable Antenna With Elevation and Azimuth Beam Switching

A reconfigurable microstrip antenna is proposed for low-cost adaptive beam-switching applications. A small patch-slot ring structure is used as the radiating element where an asymmetrical arrangement of p-i-n diodes is employed to switch the pattern in four directions. The antenna provides pattern switching of 65° and 45° in its fundamental mode for the elevation and azimuth planes, respectively. By maintaining the resonant frequency and beamwidth as relatively constant, beam switching is realized using a single feed point.
The mRNA Expression Status of Dopamine Receptor D2, Dopamine Receptor D3 and DARPP-32 in T Lymphocytes of Patients with Early Psychosis

Peripheral blood lymphocytes are an attractive tool because there is accumulating evidence indicating that lymphocytes may be utilized as a biomarker in the field of psychiatric study as they could reveal the condition of cells distributed in the brain. Here, we measured the mRNA expression status of dopamine receptor D2 (DRD2), DRD3, and dopamine and cyclic adenosine 3′,5′-monophosphate regulated phosphoprotein-32 (DARPP-32) in T lymphocytes of patients with early psychosis by quantitative real-time polymerase chain reaction (q-PCR) and explored the relationships between their mRNA levels and the psychopathological status of patients. The present study demonstrated that the mRNA expression levels of DRD3 in T lymphocytes were significantly different among controls, and in patients with psychotic disorder not otherwise specified (NOS) and schizophrenia/schizophreniform disorder. However, no significant differences in mRNA expression levels of DRD2 and DARPP-32 were found among the three groups. We found a significant positive correlation between the DRD2 mRNA level and the score of the excited factor of the Positive and Negative Syndrome Scale (PANSS) in patients with schizophrenia/schizophreniform disorder. These findings suggest that DRD3 mRNA levels may serve as a potential diagnostic biomarker differentiating patients with early psychosis from controls.
Modeling the Miocene climatic optimum: Ocean circulation

[1] Ocean circulation is investigated using the Community Climate System Model 3 (CCSM3) forced with early to middle Miocene (∼20–14 Ma) topography, bathymetry, vegetation and modern CO2. Significant bottom water formation is modeled in the Weddell Sea along with intermediate North Component Water formation in the North Atlantic. This is attributed primarily to stronger- and weaker-than-modern convective preconditioning in the Weddell and Labrador Seas, respectively. Global meridional overturning and gyre circulation is weaker in the Miocene due to weaker midlatitude westerlies in the southern hemisphere, caused by lowering of the meridional surface temperature gradient, in addition to regional influences on convection. Subsurface temperatures in the Miocene are significantly higher in the far North Atlantic, Greenland-Norwegian Seas and Arctic basin compared to the present. Ocean heat transport is symmetrical about the equator and resembles that simulated for late Cretaceous and early Cenozoic climates, suggesting the northern hemisphere dominated ocean heat transport active today developed after the middle Miocene. Simulated deep water warming in the Miocene is more than an order of magnitude lower than indicated by proxies. This discrepancy is not reconciled by higher CO2 due to the persistence of sea-ice at sites of deep water formation. This suggests that either the CCSM3 is insufficiently sensitive to Miocene boundary conditions, greater greenhouse forcing existed than is currently reconstructed, or that proxy records of warming are exaggerated. Given the diversity of global Miocene proxy records and their near-unanimous estimate of a significantly warmer Earth, the first two options are more likely.

Observations Concerning the Locking Range in a Complementary Differential $LC$  Injection-Locked Frequency Divider—Part I: Qualitative Analysis

The use of resonant injection-locked frequency dividers in frequency synthesizers has increased in recent years due to their lower power consumption compared to conventional digital prescalers. Numerous circuit ideas have been proposed, but there are few and sometimes contradictory estimates of the locking ranges (LRs) in these dividers. Despite several attempts, there is still no accurate analytical method to predict the LR. In this paper, we present a nonlinear approach based on the application of bifurcation theory to predict where the LR is wider rather than to say precisely how wide it is. The results presented have been derived by numerical bifurcation analysis using AUTO and have been verified by circuit simulations and experiments. In Part II, we will show how the insights developed in this paper lead to a rigorous design methodology.
The Community of Inquiry as a Basis for Knowledge and Learning: The Case of History

Science, social science, literary studies, philosophy, and history have all encountered challenges to the notion of “objectivity” in the wake of the Kuhnian revolution. These challenges, which problematize knowledge itself, have revived interest in the pragmatist notion of knowledge based in a community of inquiry. The related social constructivist recasting of curriculum thought in the past 15 years has been based not so much on the revision in the epistemology of the subject disciplines as in developments in learning theory and psychology. Using the discipline of history as a case study, this paper compares the scholarly community of inquiry with the community of inquiry in the classroom and examines the role of the teacher in negotiating the knowledge generated in each.
Help Wanted: A Grand Theorist of Interpersonal Relationships, Sociologist or Anthropologist Preferred

Knowledge about interpersonal relationships is currently encapsulated within type of relationship (e.g. romantic, parental), with relationship type confounded with disciplinary approach, with the characteristics of the partners usually found in that type of relationship, as well as with the nature of the relationship phenomena examined. It is argued that a critical issue for the relationship field is whether a grand, overarching theory of relationships can be developed. Such a theory would directly address the principal relationship types, delineating the similarities and differences among them with respect to the causal conditions associated with various relationship phenomena. It is further argued that an important class of causal conditions that governs behavior in all relationships is the culturally defined norms, roles and expectations associated with type of relationship, and that these cultural prescriptions - as opposed to `individualistic' causal conditions - must play an important role in any unifying theory. If so, the sociological and anthropological perspectives need to achieve better balance with the psychological perspective that is becoming dominant in theory and research on interpersonal relationships.
Accounting, Territorialization and Power

This essay aims to introduce readers to the social studies of accounting, attending in particular to the roles and relevance of Foucault’s works for this field. We provide a brief overview of social studies of accounting, discuss recent developments in Foucault oriented accounting scholarship, and position the articles that appear in this special issue in the context of these developments. In the concluding section, we argue that accounting is an inherently territorializing activity. The calculative instruments of accountancy transform not only the possibilities for personhood, they also construct the physical and abstract calculable spaces that individuals inhabit. A focus on territorializing shifts attention to the links between calculating and governing.
Nano-sensor and circuit design for anti-cancer drug detection

The development of new technologies to monitor drugs concentration directly in patient's blood is absolutely required to succeed in personalized drug therapies. In this study, Etoposide - a well-known anti-cancer drug - has been chosen as model for cyclic voltammetry detection of drugs. Carbon nanotubes are chosen as electron-transfer mediators to enhance the system sensitivity. A very low frequency and low slope triangular-wave potential is required to acquire cyclic voltammograms. Cyclic voltammograms are definitely needed for a correct identification and quantification of the drug concentration in the patient serum. The aim of the paper is to investigate the feasibility of VLSI fully-integration of cyclic voltammetry measurements as a tool to develop a low-cost chip for drug monitoring in personalized therapy. A triangular wave generator CMOS circuit is proposed by using Direct Digital Synthesis (DDS) method. The circuit is implemented in 0.18 µm technology and it presents the possibility of changing the slope of the triangular voltage in a wide range of 10 to 100mV/s.
Supervised band selection for optimal use of data from airborne hyperspectral sensors

This paper presents a practical supervised band selection procedure for airborne imaging spectrometers and Maximum Likelihood classification (MLC) as data application. The output band set is optimal in band location, width and number regarding the MLC accuracy of the classification task. The supervised algorithm is based on feature selection and requires a user-defined class set. For two given semi-natural vegetation data and class sets, the selected band sets performed superior to established vegetation band sets used in current satellite and airborne sensors, most noticeably for the first few bands. The algorithm was implemented in IDLTM/ENVITM. It may also be used for feature selection, the generation of classdiscriminate colour composites, the prioritization of already existing band sets, and the determination of the intrinsic discriminant dimensionality of the data set.
Of Sad Men and Dark Comedies: Mood and Gender Effects on Entertainment Media Preferences

Although traditional mood management theory suggests we use media to deflect sad moods and maintain good moods, various research findings reflect a more complex picture. The present study took a mixed-method, nuanced approach to basic mood management questions and investigated both open and close-ended media preferences among college students (N = 157) immediately following a positive or negative mood induction. Results show that sad (vs. happy) participants showed a preference for viewing a dark comedy or a social drama, whereas happy (vs. sad) participants showed a preference for viewing a slapstick comedy or an action adventure. Women (vs. men) showed an increased preference for romantic genres regardless of mood, whereas men showed a preference for action, suspense, and dark comedy genres. An interaction between gender and mood also emerged; sad men in particular showed a preference for dark comedies. Results are discussed in light of the emotional gratifications that mood-reflecting media may afford men and women.
Predictors of Loco‐Regional Recurrence and Cancer‐Related Death after Breast Cancer Surgery

Abstract: To determine which tumor‐related factors might predispose the patient to loco‐regional recurrence or death and the impact of these factors on the different types of events. We retrospectively analyzed the data of 1991 women between January 1998 and March 2010 for a first primary nonmetastatic breast cancer and treated with surgery and neo‐adjuvant/adjuvant therapy. The overall survival distribution was estimated using the Kaplan–Meier method. The prognostic impact of several factors on cumulative overall and loco‐regional recurrence free survival was evaluated by univariate (log‐rank test) and multivariate analysis (Cox regression). At log‐rank test, pT, nodal status, histotype, grading, lymphangioinvasive growth, tumor diameter, estrogen receptors (ER) status, progesterone receptors (PR) status, expression of Ki67, and expression of Her2/neu had a prognostic value on loco‐regional recurrence or overall survival. In the multivariate analysis grading remained the only independent predictor of loco‐regional recurrences. With regard to overall survival, the Cox model selected grading along with nodal status and PR status. Loco‐regional recurrences after breast cancer surgery are not frequent events. They are markers of tumor aggressiveness and predictor of an increased likelihood of cancer‐related death. However, loco‐regional recurrence and systemic tumor progression are partially independent events, since some prognostic factors differ.
The Effects of Instructing Teachers About Good Teaching on the Mathematics Achievement of Fourth Grade Students1

Experimental teachers were taught an instructional model based upon previous naturalistic research that had been found to characterize the behavior of effective mathematics teachers. Using a standardized mathematics achievement test administered to students at the beginning and end of the year as the dependent variable, the implementation and effect of the model were analyzed in an analysis of variance design involving the model (experimental and control), four teacher types and four student types. Use of the model proved effective and the nature of the interactions between student aptitudes, teacher style and instructional model helps to interpret the influences on students’ mathematics achievement.
Inducible Alterations of Glutathione Levels in Adult Dopaminergic Midbrain Neurons Result in Nigrostriatal Degeneration

Parkinson's disease is a neurodegenerative disorder characterized by the preferential loss of midbrain dopaminergic neurons in the substantia nigra (SN). One of the earliest detectable biochemical alterations that occurs in the Parkinsonian brain is a marked reduction in SN levels of total glutathione (glutathione plus glutathione disulfide), occurring before losses in mitochondrial complex I (CI) activity, striatal dopamine levels, or midbrain dopaminergic neurodegeneration associated with the disease. Previous in vitro data from our laboratory has suggested that prolonged depletion of dopaminergic glutathione results in selective impairment of mitochondrial complex I activity through a reversible thiol oxidation event. To address the effects of depletion in dopaminergic glutathione levels in vivo on the nigrostriatal system, we created genetically engineered transgenic mouse lines in which expression of γ-glutamyl cysteine ligase, the rate-limiting enzyme in de novo glutathione synthesis, can be inducibly downregulated in catecholaminergic neurons, including those of the SN. A novel method for isolation of purified dopaminergic striatal synaptosomes was used to study the impact of dopaminergic glutathione depletion on mitochondrial events demonstrated previously to occur in vitro as a consequence of this alteration. Dopaminergic glutathione depletion was found to result in a selective reversible thiol-oxidation-dependent mitochondrial complex I inhibition, followed by an age-related nigrostriatal neurodegeneration. This suggests that depletion in glutathione within dopaminergic SN neurons has a direct impact on mitochondrial complex I activity via increased nitric oxide-related thiol oxidation and age-related dopaminergic SN cell loss.
Analyzing Diffusion and Contagion Effects: The Urban Disorders of the 1960s

This study concerns the analysis of diffusion and contagion processes using a lognormal model of overdispersion phenomena. The urban disorders of the past decade are examined and two processes are found to exist in the 1966–67 period. One is a classic diffusion effect in which disorders are precipitated by events which are independent of each other, but lead to outcomes such as numbers of arrests which are proportional to previous disorders. The second process is a contagious one in which disturbances occur as a consequence of smaller cities imitating the behavior of large ones experiencing a disorder. It was found that the explanatory power of the interaction effect between police and black city residents tended to increase as city size increased. Concomitantly, the effects of environmental variables tended to decrease in explanatory power as city size decreased.
Psychological outcomes following the Victorian Black Saturday bushfires

Objective: We aimed to map the prevalence and predictors of psychological outcomes in affected communities 3–4 years after the Black Saturday bushfires in the state of Victoria, Australia. Methods: Baseline assessment of a longitudinal cohort study in high-, medium-, and low-affected communities in Victoria. Participants included 1017 residents of high-, medium-, and low-affected fire communities. Participants were surveyed by means of a telephone and web-based interview between December 2011 and January 2013. The survey included measures of fire-related post-traumatic stress disorder (PTSD) and general PTSD from other traumatic events, major depressive episode, alcohol use, and general psychological distress. Results: The majority of respondents in the high- (77.3%), medium- (81.3%), and low-affected (84.9%) communities reported no psychological distress on the K6 screening scale. More participants in the high-affected communities (15.6%) reported probable PTSD linked to the bushfires than medium- (7.2%) and low-affected (1.0%) communities (odds ratio (OR): 4.57, 95% confidence interval (CI): 2.61–8.00, p = 0.000). Similar patterns were observed for depression (12.9%, 8.8%, 6.3%, respectively) (OR: 1.83, 95% CI: 1.17–2.85, p = 0.008) and severe psychological distress (9.8%, 5.0%, 4.9%, respectively) (OR: 2.08, 95% CI: 1.23–3.55, p = 0.007). All communities reported elevated rates of heavy drinking (24.7%, 18.7%, 19.6%, respectively); however, these were higher in the high-affected communities (OR: 1.39, 95% CI: 1.01–1.89, p = 0.04). Severe psychological distress was predicted by fear for one’s life in the bushfires, death of someone close to them in the bushfires, and subsequent stressors. One-third of those with severe psychological distress did not receive mental health assistance in the previous month. Conclusions: Several years following the Black Saturday bushfires the majority of affected people demonstrated resilience without indications of psychological distress. A significant minority of people in the high-affected communities reported persistent PTSD, depression, and psychological distress, indicating the need for promotion of the use of health and complementary services, community-based initiatives, and family and other informal supports, to target these persistent problems.
The dynamics of professional identity of university teachers: reflecting on the ideal university teacher

The dynamics of professional identity of university teachers: reflecting on the ideal university teacher Current paper investigates development of professional identity of university teachers, observed through reflective exercises which enabled participants' to focus on their perception of the ideal university teacher. Images of the ideal university teacher were studied from two aspects: first - before the participants started teaching, and second - after they had been teaching for some time. This paper focused on how images of the ideal university teacher have changed over time, and discussed the reasons that brought about changes. There is a tendency that ideals are adapted in accordance with teaching experience. Ideals are regarded as unstable phenomena, influenced by the surrounding environment. Current paper made use of a qualitative design of reflective writing exercises and focus group interviews. The sample comprised an aggregate of 42 participants, university teachers and PhD students, and 4 focus groups. Interviews were analyzed using qualitative content analysis. The study shows that after some teaching experience, didactic knowledge and communicative skills come to the forefront of the ideal university teacher identity. The study opens the way for further and deeper discussion of images of an ideal university teacher.
