Awareness of Infants: What Do They, and We, Seek?

I study the biological foundations of human cultural intelligence, and how they are supported. I observe the development of human motives for agency, the emotions that evaluate what is discovered, and the ways interests and discoveries and feelings may be shared with others. Ed Tronick and I have been privileged to study infants closely over several decades in which ideas of the dynamic powers of the human mind have been transformed, principally by recording how infants act in intimate companionship with their mothers in the first year or two. Here I try to clarify the ways we have, for different purposes and in different environments, taken complementary routes to understanding the meaning of infant life. His responsibilities are clinical and occupied with supporting the mental health of both the infant and the mother, and the building of a strong affectionate trust for life with others. My task has been trying to understand the subtle creativity and aesthetic and moral principles that animate a widening circle of relationships for a child, and that lead to cultural learning that is rich and playful. Ed and I are lucky to be discovering what every infant wants, and privileged to be supporting pride in good company, while striving to guard against causes of despair and shame in young children and their families.
Models of emotional intelligence

COMPETING MODELS OF EMOTIONAL INTELLIGENCE Studies of emotional intelligence initially appeared in academic articles beginning in the early 1990s. By middecade, the concept had attracted considerable popular attention, and powerful claims were made concerning its importance for predicting success. Emotional intelligence is the set of abilities that accounts for how people's emotional reports vary in their accuracy and how the more accurate understanding of emotion leads to better problem solving in an individual's emotional life. More formally, we define emotional intelligence as the ability to perceive and express emotion, assimilate emotion in thought, understand and reason with emotion, and regulate emotion in the self and others (Mayer & Salovey, 1997). As of now, the academic concept has been developed over several theoretical articles (e.g., Mayer & Salovey, 1997; Salovey & Mayer, 1990) and is based on a growing body of relevant research (e.g., Averill & Nunley, 1992; Buck, 1984; Lane, Sechrest, Reidel et al., 1996; Mayer, DiPaolo, & Salovey, 1990; Mayer & Geher, 1996; Mayer & Stevens, 1994; Rosenthal, Hall, DiMatteo, Rogers, & Archer, 1979; Salovey, Mayer, Goldman, Turvey, & Palfai, 1995; see also, Salovey & Sluyter, 1997). Shortly after the academic work began, a popular book on the subject appeared (Goleman, 1995a). The book covered much of the literature reviewed in the aforementioned articles as well as considerable additional research on emotions and the brain, emotions and social behavior, and school-based programs designed to help children develop emotional and social skills.
EFFECT OF CROSS-LINKING ON THE ELECTRICAL PROPERTIES OF LDPE AND ITS LIGHTNING IMPULSE AGEING CHARACTERISTICS

Cross-linked polyethylene (XLPE) is commonly used within high voltage cable insulation. It has improved thermal and mechanical resistance compared to normal low density polyethylene (LDPE). However, the cross-linking process may also vary the electrical characteristics of the material. This paper investigates changes in electrical properties of one type of LDPE before and after cross-linking. The effective lightning resistance is also considered, as the application of repetitive lightning impulse overvoltages can be a factor in insulation material ageing of high voltage cables. The material was cross-linked using trigonox-145 peroxide with controlled concentration. Samples were moulded to have a Rogowski profile and gold coated to make sure that they are evenly electrically stressed. Obtained results show that there are reductions in both space charge injection and the permittivity of the material after it is cross-linked. The breakdown strength of the material was also improved. However, the samples studied are more susceptible to ageing due to lightning impulses.

Oops! . . . I changed it again

Duplicated passages of source code-clones-are a threat to software maintenance as modifying duplicated code causes additional change effort and bears the risk of incomplete propagation of changes to all copies. Although previous studies have investigated the consistency and threats of changing clones, changes have always been analyzed detached from another-not considering that individual clones may change more than once during their lifetime. In this paper we present our study on the patterns of consecutive changes to clones in real systems and discuss in how far they are suitable for identifying unwanted inconsistencies.
Effects of laboratory culture on compatibility between snails and schistosomes

SUMMARY The genetic control of compatibility between laboratory strains of schistosomes and their snail hosts has been studied intensively since the 1970s. These studies show (1) a bewildering array of genotype-by-genotype interactions – compatibility between one pair of strains rarely predicts compatibility with other strains, and (2) evidence for a variety of (sometimes conflicting) genetic mechanisms. Why do we observe such variable and conflicting results? One possibility is that it is partly an artifact of the use of laboratory strains that have been in culture for many years and are often inbred. Here we show that results of compatibility trials between snails and schistosomes – all derived from the same natural population – depend very much on whether one uses laboratory-cultured or field-collected individuals. Explanations include environmental effects of the lab on either host or parasite, and genetic changes in either host or parasite during laboratory culture. One intriguing possibility is that genetic bottlenecks during laboratory culture cause the random fixation of alleles at highly polymorphic loci that control the matched/mismatched status of hosts and parasites. We show that a simple model of phenotype matching could produce dose response curves that look very similar to empirical observations. Such a model would explain much of the genotype-by-genotype interaction in compatibility observed among strains.
High Prevalence of Nontraumatic Shoulder Pain in a Regional Sample of Female High School Volleyball Athletes

Background: Shoulder pain is becoming increasingly problematic in young players as volleyball gains popularity. Associations between repetitive motion and pain and overuse injury have been observed in other overhand sports (most notably baseball). Studies of adult athletes suggest that there is a shoulder pain and overuse problem present in volleyball players, but minimal research has been done to establish rates and causes in juvenile participants. Purpose: To establish rates of shoulder pain, regardless of whether it resulted in a loss of playing time, in female high school volleyball players. A secondary goal was to determine whether high repetition volumes correlated with an increased likelihood of experiencing pain. Study Design: Descriptive epidemiology study. Methods: A self-report survey focusing on the prevalence of pain not associated with a traumatic event in female high school youth volleyball players was developed. Survey questions were formulated by certified athletic trainers, experienced volleyball coaches, and biomechanics experts. Surveys were received from 175 healthy, active high school volleyball players in Iowa, South Dakota, and Minnesota. Results: Forty percent (70/175) of active high school volleyball players remembered experiencing shoulder pain not related to traumatic injury, but only 33% (23/70) reported taking time off to recover from the pain. Based on these self-reported data, activities associated with significantly increased risk of nontraumatic shoulder pain included number of years playing competitive volleyball (P = .01) and lifting weights out of season (P = .001). Players who reported multiple risk factors were more likely to experience nontraumatic shoulder pain. Conclusion: When using time off for recovery as the primary injury criterion, we found that the incidence of shoulder pain is more than twice as high as the incidence of injury reported by previous studies. Findings also indicated that the incidence of shoulder pain may be correlated with volume of previous volleyball experience.
War, Trade, and Distrust: Why Trade Agreements Don’t Always Keep the Peace

There is growing evidence that preferential trade agreements (PTAs) provide strong institutional incentives to prevent international conflict among member states, often creating the conditions of trust that can help prevent militarized aggression. We provide an approach to the study of how international institutions influence conflict behavior that considers how PTAs exclude as well as include members and create asymmetrical relationships among members that could exacerbate conflict. PTAs do more than create expectations of economic gains and reduce opportunism; they also create hierarchical relations between states, which can encourage conflict under different conditions due to distrust. We theorize these conditions for militarized international disputes, develop appropriate measures using social network analysis, and test our expectations on new PTA data during the period 1950 to 2000.
Intra-Amniotic IL-1β Induces Fetal Inflammation in Rhesus Monkeys and Alters the Regulatory T Cell/IL-17 Balance

Very low birth weight preterm newborns are susceptible to the development of debilitating inflammatory diseases, many of which are associated with chorioamnionitis. To define the effects of chorioamnionitis on the fetal immune system, IL-1β was administered intra-amniotically at ∼80% gestation in rhesus monkeys. IL-1β caused histological chorioamnionitis, as well as lung inflammation (infiltration of neutrophils or monocytes in the fetal airways). There were large increases in multiple proinflammatory cytokine mRNAs in the lungs at 24 h postadministration, which remained elevated relative to controls at 72 h. Intra-amniotic IL-1β also induced the sustained expression of the surfactant proteins in the lungs. Importantly, IL-1β significantly altered the balance between inflammatory and regulatory T cells. Twenty-four hours after IL-1β injection, the frequency of CD3+CD4+FOXP3+ T cells was decreased in lymphoid organs. In contrast, IL-17A–producing cells (CD3+CD4+, CD3+CD4−, and CD3−CD4− subsets) were increased in lymphoid organs. The frequency of IFN-γ–expressing cells did not change. In this model of a single exposure to an inflammatory trigger, CD3+CD4+FOXP3+ cells rebounded quickly, and their frequency was increased at 72 h compared with controls. IL-17 expression was also transient. Interestingly, the T cell profile alteration was confined to the lymphoid organs and not to circulating fetal T cells. Together, these results suggest that the chorioamnionitis-induced IL-1/IL-17 axis is involved in the severe inflammation that can develop in preterm newborns. Boosting regulatory T cells and/or controlling IL-17 may provide a means to ameliorate these abnormalities.
Response of Cladocera Fauna to Heavy Metal Pollution, Based on Sediments from Subsidence Ponds Downstream of a Mine Discharge (S. Poland)

Mining is recognized to deeply influence invertebrate assemblages in aquatic systems, but different invertebrates respond in different ways to mining cessation. Here, we document the response of the cladoceran assemblage of the Chechło river, S. Poland (southern Poland) to the cessation of Pb-Zn ore mining. The aquatic system includes the river and associated subsidence ponds in the valley. Some ponds were contaminated during the period of mining, which ceased in 2009, while one of the ponds only appeared after mining had stopped. We used Cladocera to reveal how the cessation of mine water discharge reflected on the structure and density of organisms. A total of 20 Cladocera taxa were identified in the sediment of subsidence ponds. Their density ranged from 0 to 109 ind. /1 cm3. The concentrations of Zn, Cd, Cu and Pb were much higher in sediments of the ponds formed during peak mining than in the ponds formed after the closure of the mine. Statistical analysis (CCA) showed that Alonella nana, Alona affinis, Alona sp. and Pleuroxus sp. strongly correlated with pond age and did not tolerate high concentrations of heavy metals (Cu and Cd). This analysis indicated that the rate of water exchange by the river flow and the presence of aquatic plants, affect species composition more than pond age itself.
Dynamic power control mechanism for interference coordination of device-to-device communication in cellular networks

Device-to-device (D2D) communication in cellular networks can bring about interference between user equipments (UEs) in cellular and D2D communications, which may decrease performance of cellular networks. In this paper, we propose dynamic power control mechanism to reduce interference and improve performance of cellular systems. The proposed mechanism excludes cellular communication UE with same resource, base station, and areas of adjacent cells from the coverage area of D2D communication UE by adjusting transmit power of the D2D communication UE. By simulations, we show that the proposed dynamic power control mechanism can improve performance of the entire communication systems.
A 60 GHz 2×2 planar phased array with SIW modified butler matrix feed

A 60 GHz 2×2 planar phased array with substrate integrated waveguide (SIW) Butler Matrix feed is designed, fabricated, and measured. The standard Butler Matrix has been modified to provide phased outputs to a planar patch array as opposed to the more conventional linear array. Additional transverse slots are etched on the bottom wall of SIW phase shifting sections to reduce the area of the Butler Matrix by 56.8% over previously reported implementations. Patch array elements with 0. 5λ spacing are excited through aperture coupling via 4 rectangular slots allocated on the top wall of the SIW Butler Matrix. The antenna was fabricated using Rogers RT5880 substrate. Measured results show higher than 5.3 dB return loss for all ports, with ports 1 and 4 measuring S11 less than -10.8 dB.
Cost-effectiveness of laparoscopy in children.

BACKGROUND Laparoscopy may offer fast recovery and improved cosmesis, but its cost has been perceived as excessive. OBJECTIVE To analyze the total hospital costs of laparoscopy vs open surgery. DESIGN Retrospective cost-effectiveness analysis evaluating all cases performed in a 36-month period (September 1995 to August 1998). Cases were evaluated for operative time, itemized cost of supplies, and length of hospitalization. SETTING Operations performed by pediatric surgeons in a tertiary care children's hospital. PATIENTS Consecutive children undergoing laparoscopic or open appendectomies, cholecystectomies, fundoplications, and splenectomies. Patients were not randomized to laparoscopy, or open surgery. INTERVENTIONS Laparoscopic procedures performed with a core set of reusable equipment and a limited number of disposable instruments. MAIN OUTCOME MEASURES Cost surplus of laparoscopy was evaluated, and compared with savings associated with decreased hospital stay, to obtain cost-effectiveness of laparoscopy per procedure. RESULTS There were 26 laparoscopic and 359 open appendectomies; 33 laparoscopic and 3 open cholecystectomies; 16 laparoscopic and 18 open fundoplications; and 16 laparoscopic and 7 open splenectomies. Excess operating costs per procedure were $442.00 for appendectomy, $634.60 for fundoplication, $847.50 for cholecystectomy, and $1551.30 for splenectomy. Hospital stay was decreased for all laparoscopies, resulting in an overall savings per laparoscopic procedure of $2369.90 for appendectomy, $5390.90 for fundoplication, $1161.00 for cholecystectomy, and $858.90 for splenectomy. CONCLUSIONS Laparoscopy is cost-effective, particularly for fundoplication, appendectomy, and cholecystectomy. Detailing the costs of supplies, operating time, and length of stay allows interinstitutional comparison and critical cost-analysis of laparoscopy. With a more selective use of reusable instruments and further shortening of operative time, the global savings of laparoscopy may increase.
Impact of Viral Dose and Major Histocompatibility Complex Class IB Haplotype on Viral Outcome in Mauritian Cynomolgus Monkeys Vaccinated with Tat upon Challenge with Simian/Human Immunodeficiency Virus SHIV89.6P

ABSTRACT The effects of the challenge dose and major histocompatibility complex (MHC) class IB alleles were analyzed in 112 Mauritian cynomolgus monkeys vaccinated (n = 67) or not vaccinated (n = 45) with Tat and challenged with simian/human immunodeficiency virus (SHIV) 89.6Pcy243. In the controls, the challenge dose (10 to 20 50% monkey infectious doses [MID50]) or MHC did not affect susceptibility to infection, peak viral load, or acute CD4 T-cell loss, whereas in the chronic phase of infection, the H1 haplotype correlated with a high viral load (P = 0.0280) and CD4 loss (P = 0.0343). Vaccination reduced the rate of infection acquisition at 10 MID50 (P < 0.0001), and contained acute CD4 loss at 15 MID50 (P = 0.0099). Haplotypes H2 and H6 were correlated with increased susceptibility (P = 0.0199) and resistance (P = 0.0087) to infection, respectively. Vaccination also contained CD4 depletion (P = 0.0391) during chronic infection, independently of the challenge dose or haplotype.
A Deterministic Built-In-Self-Test Generator Based on Cellular Automata Structures

This paper proposes a new approach for designing a cost-effective, on-chip, deterministic, built-in, self-test generator. Given a set of precomputed test vectors (obtained by an ATPG tool) with a predetermined fault coverage, a simple test vector generator (TVG) is synthesized to apply the given test set in a minimal test time. To achieve this objective, cellular automata (CA) structures have been used in which the rule space is not limited to the linear rules commonly used in CA studies recently. Based on some new notations and new formulations of CA properties, two techniques are developed to synthesize such a TVG which is used to generate an ordered/unordered deterministic test vector set. The resulting TVG is very efficient in terms of hardware size and speed performance, and is very regular and testable. Simulation of various benchmark combinational circuits has given good results when compared to alternative solutions. >
Educational Encouragement, Parenting Styles, Gender and Ethnicity as Predictors of Academic Achievement among Special Education Students

Current study examines the predictors’ of academic achievement: role of parenting styles, educational encouragement, gender and ethnicity among special education students. Participants of this study consisted 200 special education students (N = 105 boys and N = 95 girls) age varies 14 to 19 years from one school located at Kuala Lumpur, Malaysia. Results showed authoritative parenting styles were mostly used by the parents of their special education students. Significant relationships were existed in parenting styles, educational encouragement and academic achievement among special educational students. Educational encouragement from mother, father, sibling and friends, ethnicity and gender were found to be significant predictors for academic achievement. Findings of current research suggested parenting styles and educational encouragement contribute to special education student’s academic achievement. The results of the current study provide the insight for the educators, teachers and parents dealing with special education adolescents.
Person-job fit versus person-organization fit as predictors of organizational attraction and job acceptance intentions : A longitudinal study

This longitudinal field study examined the relationship between perceived person‐job (PJ) and person‐organization (PO) fit and organizational attraction, intentions to accept a job offer, and actual job offer decision. Data were collected from 193 graduate applicants prior to the selection process, during the selection process, at the end of the selection process, and after job acceptance decision. The findings showed support for the hypothesis that perceptions of PJ and PO fit influenced attraction at different stages of selection. The second hypothesis that the relationship between perceptions of PJ and PO fit and intentions to accept a job offer are mediated by organizational attraction was partially supported. Mid-selection, the relationship between PJ fit perceptions and intentions to accept a job offer was mediated by organizational attraction; in contrast, at the end of the selection process, there was a direct relationship between PJ fit perceptions and intentions. PO fit perceptions were unrelated to intentions to accept a job offer. PJ and PO fit perceptions (before and during the selection process) were unrelated to actual job acceptance decision. These findings highlight the importance of ensuring that applicants have sufficient information about the job during the recruitment and selection process.
Does physician gender affect satisfaction of men and women visiting the emergency department?

AbstractOBJECTIVE: To assess the association of physician gender with patient ratings of physician care. DESIGN: Interviewer-administered survey and follow-up interviews 1 week after emergency department (ED) visit. SETTING: Public hospital ED. PATIENTS/PARTICIPANTS: English- and Spanish-speaking adults presenting for care of nonemergent problems; of 852 patients interviewed in the ED who were eligible for follow-up, 727 (85%) completed a second interview. MEASUREMENTS AND MAIN RESULTS: We conducted separate ordered logistic regressions for women and men to determine the unique association of physician gender with patient ratings of 5 interpersonal aspects of care, their trust of the physician, and their overall ratings of the physician, controlling for patient age, health status, language and interpreter status, literacy level, and expected satisfaction. Female patients trusted female physicians more (P=.003) than male physicians and rated female physicians more positively on the amount of time spent (P=.01), on concern shown (P=.04), and overall (P=.03). Differences in ratings by female patients of male and female physicians in terms of friendliness (P=.13), respect shown (P=.74), and the extent to which the physician made them feel comfortable (P=.10) did not differ significantly. Male patients rated male and female physicians similarly on all dimensions of care (overall, P=.74; friendliness, P=.75; time spent, P=.30; concern shown, P=.62; making them feel comfortable, P=.75; respect shown, P=.13; trust, P=.92). CONCLUSIONS: Having a female physician was positively associated with women’s satisfaction, but physician gender was not associated with men’s satisfaction. Further studies are needed to identify reasons for physician gender differences in interpersonal care delivered to women.
