Beyond the Glass Ceiling: Does Gender Matter?

The representation of women in top corporate officer positions is steadily increasing. However, little is known about the impact this will have. A large literature documents that women are different from men in their choices and in their preferences, but most of this literature relies on samples of college students or workers at lower levels in the corporate hierarchy. If women must be like men to break the glass ceiling, we might expect gender differences to disappear among top executives. In contrast, using a large survey of all directors of publicly-traded corporations in Sweden, we show that female and male directors differ systematically in their core values and risk attitudes. While certain population gender differences disappear at the director level, others do not. Consistent with the findings for the Swedish population, female directors are more benevolent and universally concerned, but less power-oriented than men. However, they are less traditional and security-oriented than their male counterparts. Furthermore, female directors are slightly more risk-loving than male directors. This suggests that having a women on the board need not lead to more risk-averse decision-making.

Designing nonverbal communication for pedagogical agents: When less is more

This experimental study employed a 2 2 2 factorial design to investigate the effects of type of instruction (procedural module, attitudinal module), deictic gesture (presence, absence), and facial expression (presence, absence) on student perception of pedagogical agent persona, attitude toward the content, and learning. The interaction effect between type of instruction and agent nonverbal behavior (deictic gestures and facial expression) was also investigated. A total of 236 college students learned from an animated pedagogical agent that varied by two factors: deictic gestures and facial expression within one of two instructional environments: one training them to perform tasks within a software program (procedural learning outcome); the other focusing on changing their beliefs regarding intellectual property (attitudinal learning outcome). Results indicated that the main effects of agent facial expression and gesture as well as the interaction were significant for agent perception and learning. With regard to learning, for attitudinal instruction, participants learned more when the agent’s facial expression was present but deictic gesture was absent; however, for procedural instruction, students learned more when the agent’s gestures were present. These results are discussed in light of a preliminary pedagogical agent design principle that suggests that it is most desirable to employ the one nonverbal communicative behavior that is most appropriate to the learning outcome. 2008 Elsevier Ltd.

The relationship between suicide ideation and late-life depression.

OBJECTIVE
To describe the course of suicide ideation (SI) in primary-care based late-life depression treatment, identify predictors of SI, characterize the dynamic relationship between depression and SI, and test the hypothesis that collaborative care decreases the likelihood of reporting SI by decreasing the severity of depressive symptoms.


METHODS
This was a secondary analysis of a randomized controlled trial comparing collaborative care to usual care for late-life depression. Participants were 1,801 adults age 60 and older from eight diverse primary-care systems. Depression was measured using the Hopkins Symptoms Checklist (HSCL-20). SI was operationalized using one item from the HSCL-20. Predictors of incident SI were identified by a series of univariate analyses followed by multiple logistic regression. A mediator analysis was conducted to test the hypothesis that the effect of collaborative care on SI can be ascribed to the intervention's effect on depressive symptoms.


RESULTS
The prevalence of SI was 14% (N = 253); the cumulative incidence over 24 months was 21% (385). The likelihood that SI emerged after baseline was highly dependent on change in depression (odds ratio: 5.38, 95% confidence interval: 3.93-7.36, df = 81, t = 10.66, p <0.0001). As hypothesized, the effect of collaborative care on SI was mediated by the treatment's effect on depression.


CONCLUSION
SI is not uncommon in depressed older adults being treated in primary care. The likelihood that depressed older adults will report SI is strongly determined by the course of their depression symptoms. Providers should monitor SI throughout the course of depression treatment.
The ‘Hortus Palatinus’ at Heidelberg and the reformation of the World. Part I: The iconography of the garden

Abstract Salomon de Gaus, architect and engineer, built a garden for the Palatine Elector, Frederick V, in Heidelberg; work on it stopped in 1620. In that year de Gaus published a book about the garden (figure I).1 It is an analysis of that publication as well as of its subject, the Hortus Palatinus, which forms the matter of this essay. Without the book, with its four pages of text and 30 plates, we would know practically nothing about the garden. The cessation of work on the garden, the writing of the treatise on the Hortus Palatinus and the departure of de Caus's patron for Bohemia all occurred in close proximity during the autumn of 1619. As de Caus himself points out, the garden was never completed because of the war in Bohemia, and in fact its destruction actually began as a result of the expansion of those hostilities into the Thirty Years War with the occupation of Heidelberg in 1622. Continual destruction occurred throughout the wars, as in many instances the new terraces had breached old fortifi...
The future of sex and gender in psychology: Five challenges to the gender binary.

The view that humans comprise only two types of beings, women and men, a framework that is sometimes referred to as the "gender binary," played a profound role in shaping the history of psychological science. In recent years, serious challenges to the gender binary have arisen from both academic research and social activism. This review describes 5 sets of empirical findings, spanning multiple disciplines, that fundamentally undermine the gender binary. These sources of evidence include neuroscience findings that refute sexual dimorphism of the human brain; behavioral neuroendocrinology findings that challenge the notion of genetically fixed, nonoverlapping, sexually dimorphic hormonal systems; psychological findings that highlight the similarities between men and women; psychological research on transgender and nonbinary individuals' identities and experiences; and developmental research suggesting that the tendency to view gender/sex as a meaningful, binary category is culturally determined and malleable. Costs associated with reliance on the gender binary and recommendations for future research, as well as clinical practice, are outlined. (PsycINFO Database Record
Generative representations for evolutionary design automation

Generative Representations for Evolutionary Design Automation A dissertation presented to the Faculty of the Graduate School of Arts and Sciences of Brandeis University, Waltham, Massachusetts by Gregory S. Hornby In this thesis the class of generative representations is de ned and it is shown that this class of representations improves the scalability of evolutionary design systems by automatically learning inductive bias of the design problem thereby capturing design dependencies and better enabling search of large design spaces. First, properties of representations are identi ed as: combination, controlow, and abstraction. Using these properties, representations are classi ed as non-generative, or generative. Whereas non-generative representations use elements of encoded artifacts at most once in translation from encoding to actual artifact, generative representations have the ability to reuse parts of the data structure for encoding artifacts through controlow (using iteration) and/or abstraction (using labeled procedures). Unlike non-generative representations, which do not scale with design complexity because they cannot capture design dependencies in their structure, it is argued that evolution with generative representations can better scale with design complexity because of their ability to hierarchically create assemblies of modules for reuse, thereby enabling better search of large design spaces. Second, GENRE, an evolutionary design system using a generative representation, is described. Using this system, a non-generative and a generative representation are compared on four classes of designs: three-dimensional static structures constructed from voxels; neural networks; actuated robots controlled by oscillator networks; and neural network controlled robots. Results from evolving designs in these substrates show that the evolutionary design system is capable of nding solutions of higher tness with the generative representation than with the non-generative representation. This improved performance is shown to be a result of the generative representation's ability to
Same-Sex Couples, Families, and Marriage: Embracing and Resisting Heteronormativity 1

This article focuses on lesbian and gay couples and families and the politics of same-sex marriage. Drawing from the literature on same-sex couples, same-sex marriage, and queer theory’s concept of heteronormativity, we argue that gay and lesbian couples and families both affirm and challenge heterosexual and gendered family forms. First, we review literature that discusses how same-sex relationships and families are similar to and different from conventional heterosexual relationships and families. Second, we discuss the socio-legal and cultural inequalities faced by LGBT families. Third, we discuss the politics of same-sex marriage, examining the debate among social conservatives, pro-marriage activists, and queer critics over the desirability of same-sex marriage. We conclude that the growing visibility of LGBT couples and families has made their exclusion from the institution of marriage more conspicuous and that recognition of LGBT relationships and families seems likely to increase.
Cats and dogs and the risk of atopy in childhood and adulthood.

BACKGROUND
Exposure to cats and dogs during childhood has been linked to a lower risk of developing allergies. It remains unclear whether this is due to selective avoidance of pets by families with a history of allergies. The effects of pet ownership in adulthood are unknown.


OBJECTIVES
We sought to assess the association between cat and dog ownership in childhood and early adulthood and the development of atopy in a population-based birth cohort of 1037 subjects.


METHODS
Ownership of cats or dogs between birth and age 9 years and between the ages of 18 and 32 years was reported. Skin prick tests to common allergens were performed at 13 and 32 years.


RESULTS
There was no evidence that families with a history of atopy avoided owning pets. There were significant cat-by-dog interactions for the development of atopy in both childhood and adulthood. Children who had owned both a cat and a dog were less likely to be atopic at age 13 years. Living with only one of these animals was not protective against atopy. Among those who were not atopic by age 13 years, having both a cat and a dog in adulthood was associated with a lower risk of new atopy by age 32 years. This association was only significant among those with a parental history of atopy. These effects were independent of a range of potential confounding factors.


CONCLUSIONS
There is a synergistic interaction between cat and dog exposure that is associated with a lower risk of developing atopy in childhood and young adulthood.
Diagnostic value of end tidal capnography in patients with hyperglycemia in the emergency department

BACKGROUND
Diabetic Ketoacidosis (DKA) is a potentially life-threatening emergency that requires prompt diagnosis and treatment. In paediatric populations an end tidal capnography value greater than 36 mmHg was found to be 100 % sensitive in ruling out DKA.


METHODS
A cross sectional observational study of adults ≥ 17 years of age presenting to the emergency department between January 2014 and May 2014 with glucose > 550 mg/dL. In all patients, nasal capnography and venous blood gas analysis were performed prior to any insulin or intravenous fluid administration. The diagnosis of DKA was based on the presence of anion gap metabolic acidosis, hyperglycaemia and ketonemia. The overall diagnostic performance (area under the curve [AUC]), sensitivity, specificity and likelihood ratios at different end tidal CO2 (ETCO2) cut-offs were determined.


RESULTS
71 patients were enrolled in the study of which 21 (30 %) met the diagnosis of DKA. The area under the curve for ETCO2 was 0.95 with a 95 % CI of 0.91 to 0.99. Test sensitivity for DKA at ETCO2 level ≥35 mmHg was 100 % (95 % CI, 83.9-100). An ETCO2 level ≤ 21 mmHg was 100 % specific (95 % CI, 92.9-100.0) for DKA.


CONCLUSION
Nasal capnography exhibits favourable diagnostic performance in detecting patients with or without DKA among those who present to the emergency department with a glucometer reading > 550 mg/dL.
[Validity of self-reported diabetes and its determinants: evidences from the Bambuí study].

OBJECTIVE
To assess the validity of self-reported diabetes and its determinants in the elderly.


METHODS
Cross-sectional study including 1,492 subjects aged >or= 60 years, which corresponds to 86% of all residents in this age group living in the municipality of Bambuí, Southeastern Brazil, in 1997. The validity of self-reported diabetes was assessed comparing to diabetes mellitus defined by medical criteria (fasting glucose > 126 mg/dl or current treatment). Multivariate analysis was carried out to assess factors independently associated with sensitivity and specificity.


RESULTS
The prevalence of diabetes mellitus and self-reported diabetes were 14.5% and 11.7%, respectively. Sensitivity and specificity of self-reported diabetes were 57.1% (95% CI: 50.3;63.8) and 96.9% (95% CI: 94.7;97.0), respectively. Medical visits in the previous two years (PR=3.78), as well as 1-3 (PR=1.90) and > 4 years (PR=1.55) of schooling were positively and independently associated with sensitivity. Medical visits in the previous two years (PR= 0.96) and female sex (PR = 0.97) were negatively and independently associated with specificity.


CONCLUSIONS
The study results indicated that self-reported diabetes should not be either used to estimate the prevalence of diabetes mellitus or to identify individuals with the disease in the study population. Schooling and medical visits were determinants of the elderly awareness of being diabetics, indicating that these modifiable characteristics may play a role in secondary and tertiary prevention.
Aspect Based Sentiment Analysis with Gated Convolutional Networks

Aspect based sentiment analysis (ABSA) can provide more detailed information than general sentiment analysis, because it aims to predict the sentiment polarities of the given aspects or entities in text. We summarize previous approaches into two subtasks: aspect-category sentiment analysis (ACSA) and aspect-term sentiment analysis (ATSA). Most previous approaches employ long short-term memory and attention mechanisms to predict the sentiment polarity of the concerned targets, which are often complicated and need more training time. We propose a model based on convolutional neural networks and gating mechanisms, which is more accurate and efficient. First, the novel Gated Tanh-ReLU Units can selectively output the sentiment features according to the given aspect or entity. The architecture is much simpler than attention layer used in the existing models. Second, the computations of our model could be easily parallelized during training, because convolutional layers do not have time dependency as in LSTM layers, and gating units also work independently. The experiments on SemEval datasets demonstrate the efficiency and effectiveness of our models. 1
Chimeric piggyBac transposases for genomic targeting in human cells

Integrating vectors such as viruses and transposons insert transgenes semi-randomly and can potentially disrupt or deregulate genes. For these techniques to be of therapeutic value, a method for controlling the precise location of insertion is required. The piggyBac (PB) transposase is an efficient gene transfer vector active in a variety of cell types and proven to be amenable to modification. Here we present the design and validation of chimeric PB proteins fused to the Gal4 DNA binding domain with the ability to target transgenes to pre-determined sites. Upstream activating sequence (UAS) Gal4 recognition sites harbored on recipient plasmids were preferentially targeted by the chimeric Gal4-PB transposase in human cells. To analyze the ability of these PB fusion proteins to target chromosomal locations, UAS sites were randomly integrated throughout the genome using the Sleeping Beauty transposon. Both N- and C-terminal Gal4-PB fusion proteins but not native PB were capable of targeting transposition nearby these introduced sites. A genome-wide integration analysis revealed the ability of our fusion constructs to bias 24% of integrations near endogenous Gal4 recognition sequences. This work provides a powerful approach to enhance the properties of the PB system for applications such as genetic engineering and gene therapy.
A novel approach for dynamic traffic lights management based on Wireless Sensor Networks and multiple fuzzy logic controllers

This paper proposes a novel approach to dynamically manage the traffic lights cycles and phases in an isolated intersection. The target of the work is a system that, comparing with previous solutions, offers improved performance, is flexible and can be implemented on off-the-shelf components. The challenge here is to find an effective design that achieves the target while avoiding complex and computationally expensive solutions, which would not be appropriate for the problem at hand and would impair the practical applicability of the approach in real scenarios. The proposed solution is a traffic lights dynamic control system that combines an IEEE 802.15.4 Wireless Sensor Network (WSN) for real-time traffic monitoring with multiple fuzzy logic controllers, one for each phase, that work in parallel. Each fuzzy controller addresses vehicles turning movements and dynamically manages both the phase and the green time of traffic lights. The proposed system combines the advantages of the WSN, such as easy deployment and maintenance, flexibility, low cost, noninvasiveness, and scalability, with the benefits of using four parallel fuzzy controllers, i.e., better performance, fault-tolerance, and support for phase-specific management. Simulation results show that the proposed system outperforms other solutions in the literature, significantly reducing the vehicles waiting times. A proof-of-concept implementation on an off-the-shelf device proves that the proposed controller does not require powerful hardware and can be easily implemented on a low-cost device, thus paving the way for extensive usage in practice. 2015 Elsevier Ltd.

Models for traffic control

Traffic models play an important role in both today’s traffic research and in many traffic applications such as traffic flow prediction, incident detection and traffic control. In this paper we concentrate on motorway traffic models for traffic control. First, we discuss why traffic control is important for both practice and research. We also argue why a model-based approach to traffic control is used and how it is implemented in traffic applications. Every traffic application requires specific features of the traffic model. After classifying the models based on these features, we look in detail at three macroscopic models since these models are best suited for implementation in traffic control systems. We conclude with an illustrative example that illustrates a model-based predictive control approach for ramp metering. Introduction Traffic congestion and traffic control Traffic congestion on motorways is becoming an ever more pressing problem in countries all over the world. One approach to tackle congestion could be the construction of new roads to enlarge the capacity of the traffic infrastructure. This approach is very costly and it is often not possible due to environmental or societal constraints. In addition, it can only be executed on the longer term. So there is a need for another, short-term solution. This short-term solution exists of controlling traffic in such a way that congestion is solved, reduced, or at least postponed.

Prevalence of orthostatic hypotension

Orthostatic hypotension (OH) is defined as a fall in blood pressure of at least 20 mmHg systolic or 10 mmHg diastolic when standing or during head-up tilt testing. The prevalence of OH increases with age, with disorders that affect autonomic nerve transmission, and with increasingly severe orthostatic stress. In normal elderly subjects, the prevalence of OH is reported to be between 5 and 30%. The actual prevalence depends on the conditions during diagnostic testing, such as the frequency of blood pressure recordings, the time of day and the degree of orthostatic stress. Elderly subjects are often taking medications, such as antihypertensives and diuretics that can cause or aggravate OH. Neurological diseases such as diabetic neuropathy, Parkinson’s disease, multiple system atrophy and the autonomic neuropathies further increase the likelihood of OH. The development of OH in normal subjects is associated with an increased mortality rate. OH in diabetes is also associated with a significant increase in mortality rate.
