Mothers Who Kill Their Children: Understanding the Acts of Moms from Susan Smith to the "Prom Mom"

A special kind of horror is reserved for mothers who kill their children. Cases such as those of Susan Smith, who drowned her two young sons by driving her car into a lake, and Melissa Drexler, who disposed of her newborn baby in a restroom at her prom, become media sensations. Unfortunately, in addition to these high-profile cases, hundreds of mothers kill their children in the United States each year. The question most often asked is, why? What would drive a mother to kill her own child? Those who work with such cases, whether in clinical psychology, social services, law enforcement or academia, often lack basic understandings about the types of circumstances and patterns which might lead to these tragic deaths, and the social constructions of motherhood which may affect women's actions. These mothers oftentimes defy the myths and media exploitation of them as evil, insane, or lacking moral principles, and they are not a homogenous group. In obvious ways, intervention strategies should differ for a teenager who denies her pregnancy and then kills her newborn and a mother who kills her two toddlers out of mental illness or to further a relationship. A typology is needed to help us to understand the different cases that commonly occur and the patterns they follow in order to make possible more effective prevention plans. Mothers Who Kill Their Children draws on extensive research to identify clear patterns among the cases of women who kill their children, shedding light on why some women commit these acts. The characteristics the authors establish will be helpful in creating more meaningful policies, more targeted intervention strategies, and more knowledgeable evaluations of these cases when they arise.
Effect of ramped light intensity on polymerization force and conversion in a photoactivated composite.

PURPOSE This study evaluated the effect of ramped light intensity on the polymerization shrinkage forces and degrees of conversion (DC) of a hybrid composite. MATERIALS AND METHODS Composite samples were bonded between two steel rods (2.50 mm diameter, 1.25 mm apart, configuration factor = 1.0) mounted in a universal testing machine using a constant displacement mode. Polymerization contraction force was recorded for 250 seconds under four light exposure conditions: group 1, STD: (40 s x 800 mW/cm2); group 2, EXP: (150 mW/cm2 logarithmic increase to 800 mW/cm2 over 15 s) + (25 s x 800 mW/cm2); group 3, 2-STEP: (10 s x 150 mW/cm2) + (30 s x 800 mW/cm2); group 4, MED: (80 s x 400 mW/cm2). Maximum curing force (N250s) and maximum force rate of the four groups were compared using one-way analysis of variance (ANOVA) (alpha = 0.05) and the Tukey test. Degrees of conversion obtained with STD, EXP, and MED cure modes were evaluated at three depths (top surface, 1 mm, and 2 mm) using Fourier transform infrared spectroscopy (FTIR). RESULTS Maximum rates of polymerization shrinkage force development and standard deviations (SD), in ascending order, were group 4, MED: 0.33 +/- 0.03 N/s; group 2, EXP: 0.35 +/- 0.06 N/s; group 1, STD: 0.44 +/- 0.03 N/s; and group 3, 2-STEP: 0.46 +/- 0.07 N/s. Maximum rates of polymerization shrinkage force development of group 2, EXP and group 4, MED were statistically equivalent and lower than those of group 1, STD and group 3, 2-STEP. Maximum shrinkage forces (+/- SD), in ascending order, were group 2, EXP: 20.4 +/- 2.5 N; group 4, MED: 25.8 +/- 1.0 N; group 3, 2-STEP: 27.4 +/- 5.8 N, and group 1, STD: 30.5 +/- 2.7 N. Maximum force of the EXP mode was statistically lower than MED, 2-STEP, and STD curing modes. The EXP ramp was successful in reducing the conversion rate at the top surface and at 1.0-mm depth, but it did not affect the total conversion compared to the STD 40-second cure mode. There was no difference in DC at the top surface and 1-mm depth with mode of cure. The MED cure mode resulted in a higher DC than the EXP mode at a depth of 2 mm. CLINICAL SIGNIFICANCE Maximum shrinkage force and force rate exhibited during the first 250 seconds of polymerization were significantly lower using a ramped light intensity exposure. Ramped light intensity decreased conversion rate at the top surface and at 1.0-mm depth and did not affect the total extent of conversion compared to a standard 40-second, single-intensity cure mode. The slower conversion rate resulting from ramped light intensity helped to reduce the rate and maximum polymerization stress, but would not be expected to compromise the physical properties for the restorative material, since similar degrees of conversion were obtained.
The Interaction of the Chaperonin Tailless Complex Polypeptide 1 (Tcp1) Ring Complex (Tric) with Ribosome-Bound Nascent Chains Examined Using Photo-Cross-Linking

The eukaryotic chaperonin tailless complex polypeptide 1 (TCP1) ring complex (TRiC) (also called chaperonin containing TCP1 [CCT]) is a hetero-oligomeric complex that facilitates the proper folding of many cellular proteins. To better understand the manner in which TRiC interacts with newly translated polypeptides, we examined its association with nascent chains using a photo-cross-linking approach. To this end, a series of ribosome-bound nascent chains of defined lengths was prepared using truncated mRNAs. Photoactivatable probes were incorporated into these 35S- labeled nascent chains during translation. Upon photolysis, TRiC was cross-linked to ribosome-bound polypeptides exposing at least 50–90 amino acids outside the ribosomal exit channel, indicating that the chaperonin associates with much shorter nascent chains than indicated by previous studies. Cross-links were observed for nascent chains of the cytosolic proteins actin, luciferase, and enolase, but not to ribosome-bound preprolactin. The pattern of cross-links became more complex as the nascent chain increased in length. These results suggest a chain length–dependent increase in the number of TRiC subunits involved in the interaction that is consistent with the idea that the substrate participates in subunit-specific contacts with the chaperonin. Both ribosome isolation by centrifugation through sucrose cushions and immunoprecipitation with anti-puromycin antibodies demonstrated that the photoadducts form on ribosome-bound polypeptides. Our results indicate that TRiC/CCT associates with the translating polypeptide shortly after it emerges from the ribosome and suggest a close association between the chaperonin and the translational apparatus.
Sonophoresis Using Ultrasound Contrast Agents: Dependence on Concentration

Sonophoresis can increase skin permeability to various drugs in transdermal drug delivery. Cavitation is recognized as the predominant mechanism of sonophoresis. Recently, a new logical approach to enhance the efficiency of transdermal drug delivery was tried. It is to utilize the engineered microbubble and its resonant frequency for increase of cavitation activity. Actively-induced cavitation with low-intensity ultrasound (less than ~1 MPa) causes disordering of the lipid bilayers and the formation of aqueous channels by stable cavitation which indicates a continuous oscillation of bubbles. Furthermore, the mutual interactions of microbubble determined by concentration of added bubble are also thought to be an important factor for activity of stable cavitation, even in different characteristics of drug. In the present study, we addressed the dependence of ultrasound contrast agent concentration using two types of drug on the efficiency of transdermal drug delivery. Two types of experiment were designed to quantitatively evaluate the efficiency of transdermal drug delivery according to ultrasound contrast agent concentration. First, an experiment of optical clearing using a tissue optical clearing agent was designed to assess the efficiency of sonophoresis with ultrasound contrast agents. Second, a Franz diffusion cell with ferulic acid was used to quantitatively determine the amount of drug delivered to the skin sample by sonophoresis with ultrasound contrast agents. The maximum enhancement ratio of sonophoresis with a concentration of 1:1,000 was approximately 3.1 times greater than that in the ultrasound group without ultrasound contrast agent and approximately 7.5 times greater than that in the control group. These results support our hypothesis that sonophoresis becomes more effective in transdermal drug delivery due to the presence of engineered bubbles, and that the efficiency of transdermal drug delivery using sonophoresis with microbubbles depends on the concentration of microbubbles in case stable cavitation is predominant.
Loss of strength contributes more to physical disability after stroke than loss of dexterity

Objective: The major contributors to physical disability after stroke are considered to be the negative impairments of loss of dexterity (defined here as loss of the ability to co-ordinate muscle activity in the performance of any motor task) and loss of strength. The aims of this study were: (1) to determine the relative contributions of strength and dexterity to function during recovery after stroke; and (2) to determine the predictive value of initial strength, dexterity and function on long-term function after stroke. Design: A longitudinal descriptive study. Setting: The inpatient and outpatient rehabilitation departments of two metropolitan hospitals. Subjects: Twenty-two patients undergoing rehabilitation after acute stroke participated. Main outcome measures: Strength and dexterity of the elbow flexors and extensors were measured, along with arm function, at 3, 5, 7, 9, 11, 15, 19, 23 and 27 weeks after stroke. Results: Standard multiple linear regression analysis demonstrated that strength and dexterity in total contributed significantly to function at all times (r2 = 0.66-0.82, p < 0.0001). Furthermore, strength always made an additional separate contribution to function (r2 0.05-0.26, p<0.05). Function at week 3 was the best clinical predictor of function at week 27 (r2 0.55, p < 0.001). Conclusions: Loss of strength is a more significant contributor than loss of dexterity to physical disability after stroke. This suggests that, where significant weakness is present, exercise designed to increase strength will be required to decrease disability.
ODMT: On-demand Inter-domain Multicast Tunneling

The tussle in IP multicast, where different enablers have interests that are adverse to each other, has led to a halt in inter-provider multicast deployment and created a situation in which enabling inter-domain multicast routing is considered a deterrent for network providers. This paper presents ODMT (On-demand Inter-domain Multicast Tun- neling), an on-demand inter-provider multicast tunneling that is autonomous in operation and manageable through its definable policy control. In the architectural design, we propose a new approach of enabling inter-provider multicast by decoupling the control-plane and forwarding-plane. Focusing on the control-plane without changing the forwarding- plane, our solution changes the traditional open multicast service model into a more manageable service model in inter-domain multicast operation, hence it eases the Internet-wide multicast deployment.
Paper, pen and ink: An innovative system and software framework to assist writing rehabilitation

Handwriting analysis and rehabilitation is an actively explored area in the diagnosis and treatment of Parkinson's disease, which is usually performed in an ambulatory setting under direct supervision of a clinician. Technology can play an important role to reduce the need of therapist assistance and to enhance diagnostic precision through the computation of non-subjective handwriting quality metrics. This paper introduces an innovative handwriting rehabilitation system for PD patients, which ensures a natural writing experience as it is based on pen, ink and paper (as opposed to tablet and stylus). The system is designed for human-in-the loop operation and it can analyze handwriting in real-time and provide vocal feedback to guide the patient during the execution of exercises. We present a detailed comparative characterization of the key components of the system, namely wireless digital pens; in addition, in-field test assessed the system usability regarding its ease of use, calibration precision and vocal feedback effectiveness.
Identification of mechanical properties of brain parenchyma for brain surgery haptic simulation

Dissection and removal of lesion area are fundamental operations in brain surgery. In order to correctly reproduce dissection and removal in brain surgery haptic simulation, mechanical properties of brain tissue must be investigated. In this work, porcine brains are used as specimens. Mechanical properties such as density, Poisson's ratio, Young's modulus, damping coefficient, and fracture stress of porcine brain parenchyma are measured and identified. Since haptic simulations require real-time computation of deformation and fracture of brain tissue, a linear finite element model and Rayleigh damping model are used. The Rayleigh damping coefficients are identified by solving optimization problems, so that the error between experimental results and simulation results is minimized.
Dual-beam interferometry for ocean surface current vector mapping

The recent use of along-track interferometry (ATI) in synthetic aperture radar (SAR) has shown promise for synoptic measurement of ocean surface currents. ATI-SARs have been used to estimate wave fields, currents, and current features. This paper describes and analyzes a dual-beam along-track interferometer to provide spatially resolved vector surface velocity estimates with a single pass of an aircraft. The design employs a pair of interferometer beams, one squinted forward and one squinted aft. Each interferometric phase is sensitive to the component of surface Doppler velocity in the direction of the beam. Therefore, a proper combination of these measurements provides a vector surface velocity estimate in one pass of the aircraft. The authors find that precise measurements dictate widely spaced beams and that the spatial resolution for the squinted SAR is essentially identical to the sidelooking case. Practical instrument design issues are discussed, and an airborne system currently in development is described. Through computer simulation, they observe the azimuthal displacement of interferometric phases by moving surfaces identical to those of conventional SAR and find that such displacement can bias the estimated surface velocity.
Use of a Pressure Vest to Reduce the Physiological Arousal of People with Profound Intellectual and Physical Disabilities During Routine Nail Care

This single subject ABAB study explored whether the use of a commercially available deep pressure vest would decrease physiological arousal in a male with profound mental retardation during nail care activities. Psychophysiological responses of electrodermal activity, skin temperature, electromyography, and heart rate were used as indicators of physiological arousal and recorded using the NeXus-10. Visual and statistical analysis revealed that the use of the deep pressure vest did not reduce physiological arousal during nail care.
Measuring the Effects of Small Group Deliberation on Public Attitudes towards Sentencing: Benefits and Challenges

Abstract This article reports on the outcomes of small group deliberations on levels of punitiveness and public confidence in the sentencing functions of Australian criminal courts, conducted as part of a larger project investigating public attitudes to sentencing. One hypothesis of the project as a whole was that a more informed and involved public is likely to be less punitive in their views on the sentencing of offenders, and to express less cynical views about the role of sentencing courts. The aim of the small group deliberations as part of the broader project was to engender a more thoughtful and considered approach by participants to issues around sentencing. It was hypothesised that the opportunity to discuss, deliberate and consider would lead to a measurable reduction in punitiveness and an increase in people's confidence in the courts. While the results do indeed indicate such changes in attitudes, the current study also shed light on some of the conceptual, methodological and practical challenges inherent in this type of research.
Bullying, depression, and suicidal ideation in Finnish adolescents: school survey

Abstract Objective: To assess the relation between being bullied or being a bully at school, depression, and severe suicidal ideation. Design: A school based survey of health, health behaviour, and behaviour in school which included questions about bullying and the Beck depression inventory, which includes items asking about suicidal ideation. Setting: Secondary schools in two regions of Finland. Participants: 16410 adolescents aged 14-16. Results: There was an increased prevalence of depression and severe suicidal ideation among both those who were bullied and those who were bullies. Depression was equally likely to occur among those who were bullied and those who were bullies. It was most common among those students who were both bullied by others and who were also bullies themselves. When symptoms of depression were controlled for, suicidal ideation occurred most often among adolescents who were bullies. Conclusion: Adolescents who are being bullied and those who are bullies are at an increased risk of depression and suicide. The need for psychiatric intervention should be considered not only for victims of bullying but also for bullies. Key messages About 1 in 10 schoolchildren report being bullied weekly at school Adolescents who are bullied or who are bullies have an increased risk of depression and suicidal ideation Bullies are often as depressed as those who are bullied, and suicidal ideation is even more common among bullies Interventions aimed at reducing bullying in schools, as well as psychiatric assessment and treatment of bullies and those who are bullied, might also prevent depression and suicidal ideation
Focal therapy in prostate cancer: the current situation

Prostate cancer is one of the most significant pathologies in the field of urology. The adoption of screening strategies and improvements in biopsies have resulted in an increase in early-stage tumour detection. Radical global therapies provide very good oncological results in localised prostate cancer. However, excess treatment in low- and, in some cases, intermediate-risk groups affects the quality of life of these patients. In the case of localised prostate cancer, focal therapies offer a minimally invasive option with good results with respect to established treatments. Although this is currently not a standard treatment, it represents the therapeutic approach with the greatest potential. This literature review has the following objectives: to define selection criteria for patients who are candidates for focal therapy, to assess the current situation and results of the different therapeutic options, and to define procedures in cases of recurrence and for follow-ups. We concluded that focal therapy is a viable therapeutic alternative for localised prostate cancer, specifically cryosurgery and high-intensity targeted ultrasound, which have acceptable oncologic results and a lower comorbidity compared with global treatments. Studies with a high level of scientific evidence are still needed to validate these results. Acquisition of evidence A search was carried out on the Medline (PubMed), EMBASE, Web of Science and Cochrane databases of all papers published before 31 July 2013. We included clinical studies and literature reviews that evaluated primary focal therapy for prostate cancer confirmed by biopsy and excluded focal rescue therapy studies. The keywords used were focal therapy and prostate cancer. Initially, we found 42 articles; 15 studies were excluded because they did not meet the minimum criteria for inclusion. A total of 1350 cases were treated throughout 27 studies.

Detecting Duplicates over Sliding Windows with RAM-Efficient Detached Counting Bloom Filter Arrays

Detecting duplicates over sliding windows is an important technique for monitoring and analysing data streams. Since recording the exact information of elements in a sliding window can be RAM-resource-intensive and introduce an unacceptable search complexity, several approximate membership representation schemes have been proposed to build in-memory fast indices. However, various challenges facing RAM utilization and scalability remain. This paper proposes a Detached Counting Bloom filter Array (DCBA) to flexibly and efficiently detect duplicates over sliding windows. A DCBA consists of an array of detached counting Bloom filters (DCBFs), where each DCBF is essentially a Bloom filter that is associated with a detached timer (counter) array. The DCBA scheme functions as a circular FIFO queue and keeps a filling DCBF for accommodating fresh elements and a decaying DCBF for evicting stale elements. DCBA allows the timer arrays belonging to fully filled DCBFs to be offloaded to disks to greatly improve the memory space efficiency. The fully filled DCBFs will remain stable until their elements become stale, which allows a DCBA to be efficiently replicated for the purpose of data reliability or information sharing. Further, DCBA can be cooperatively maintained by clustered nodes, which provides scalable solution for mining massive data streams. Mathematical analysis and experimental results show that a DCBA (containing 64 DCBFs) requires less than 10% of its components to be kept in RAM while maintaining more than 95% of its query performance, which significantly outperforms existing schemes in memory efficiency and scalability.
Analytical modelling and experimental validation of the dynamic behaviour of permanent magnet synchronous machine based wind energy converter

This paper deals with the modelling and simulation of permanent magnet synchronous generator (PMSG) directly coupled to the turbine of a stand alone wind energy converter (WEC). First, the model of each component constituting a stage of the conversion chain is proposed and implemented in Matlab environment. Then, based on simulation results, the dynamic behavior of the different components of the WEC is analysed with respect to the variations of random wind speed and electrical load. The simulation results are validated by experimental measurements performed with a Bergey BWC XL1 wind turbine
Peabody Developmental Motor Scales

Gross Motor Quotient (GMQ) This quotient measures the ability to utilize the large muscle systems to move from place to place, assume a stable posture when not moving, react automatically to environmental changes, and catch/throw objects. High scores on this composite are made by children with well-developed gross motor abilities. These children would have above average movement and balance skills. They are likely to be children who could be described as agile, well-coordinated, and graceful in their movements. Low scores are made by children who have weak movement and balance skills. These children may have difficulty in learning to crawl, walk, and run. A deficit in gross motor abilities can be mild and the child's movements may be described as clumsy and uncoordinated. More severe gross motor problems may limit a child's use of their legs to such a degree that they will need assistance to move from place to place.
