Mathematical Mode of Thought in Architecture Design Education: A case study

Integrating mathematics and architecture design curricula has resulted in a positive change in students’ abilities to apply mathematics to architectural design. The authors developed the first-year calculus-with-applications course based on the Realistic Mathematics Education approach. In order to encourage students to use mathematics in design projects, the integration of mathematics and architecture education was continued by developing and evaluating the second-year Mathematical Aspects in Architectural Design course based on the Mathematics as a Service Subject approach. The paper considers three directions of geometrical complexity studied in the course with a focus on the process of project-based learning of curved surfaces.     

Body Beautiful: medical aesthetics and the reconstruction of urban Britain in the 1940s

The convergence of two seemingly distinct discourses - those of medical science and planning - in the period of urban reconstruction at the close of the Second World War is discussed. It is suggested that planners in 1940s Britain conceptualized urban reconstruction by employing the visual imagery and rhetoric of contemporary 'medical aesthetics'. The convergence of these ideas was purposeful: medical knowledge and its newly emerging aesthetics transplanted itself easily into the imaginative realms of urban reconstruction so that planners and architects alike could visualize the social, moral and architectural improvements to be made to the city in terms of diagnosis, cure and treatment. Reconstruction was not simply building cities anew; it also involved a vision of post-war life in its full cultural complexity.     

"Memory illusions: False recall and recognition in adults with Asperger's syndrome": Correction to Bowler et al. (2000).

Reports an error in "Memory illusions: False recall and recognition in adults with Asperger's syndrome" by Dermot M. Bowler, John M. Gardiner, Sarah Grice and Pia Saavalainen (Journal of Abnormal Psychology, 2000[Nov], Vol 109[4], 663-672). On page 665, Figure 1, the figure caption incorrectly reads, "Serial position effects for the Asperger and control groups of participants. Gray boxes = Asperger; black boxes = controls." The correct Figure 1 caption appears in the correction. (The following abstract of the original article appeared in record 2000-12687-011.) As persons on the autistic spectrum are known not to use semantic features of word lists to aid recall, they might show diminished susceptibility to illusory memories that typically occur with lists of associated items. Alternatively, since such individuals also have poor source monitoring, they might show greater susceptibility. The authors found that adults with Asperger's syndrome (n?=?10) recalled similar proportions of a nonpresented strong associate of the study list items, compared with controls (n?=?15). In Exp 2, rates of true and false recognition of study list associates did not differ significantly between Asperger (n?=?10) and control (n?=?10) participants. Moreover, the Asperger participants made fewer remember and more know judgments than controls for veridical but not for false recognitions. Thus, deficits found in some aspects of memory in people with Asperger's syndrome do not affect their susceptibility to memory illusions.

Academic control and action control in the achievement of college students: A longitudinal field study.

A contradiction to the typical pattern of academic success occurs when bright, enthusiastic high school students fail after entering university. Two measures, perceived academic control and action control (i.e., preoccupation with failure) were administered to 524 college students at the beginning of a 2-semester course. Achievement-related cognitions, emotions, motivation, and final grades were measured at the end of the course. High-academic-control students exerted more effort, reported less boredom and anxiety, were more motivated, used self-monitoring strategies more often, felt more in control of their course assignments and of life in general, believed they performed better, and obtained higher final grades. Failure-preoccupied students received higher final grades, which corroborated their self-reported performance. Of note, high-control, high-failure-preoccupied students outperformed the other 3 groups by 1 to 2 letter grades. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emotionally expressive coping predicts psychological and physical adjustment to breast cancer.

This study tested the hypothesis that coping through emotional approach, which involves actively processing and expressing emotions, enhances adjustment and health status for breast cancer patients. Patients (n ?=?92) completed measures within 20 weeks following medical treatment and 3 months later. Women who, at study entry, coped through expressing emotions surrounding cancer had fewer medical appointments for cancer-related morbidities, enhanced physical health and vigor, and decreased distress during the next 3 months compared with those low in emotional expression, with age, other coping strategy scores, and initial levels on dependent variables (except medical visits) controlled statistically. Expressive coping also was related to improved quality of life for those who perceived their social contexts as highly receptive. Coping through emotional processing was related to one index of greater distress over time. Analyses including dispositional hope suggested that expressive coping may serve as a successful vehicle for goal pursuit. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Determining inventory levels in a CONWIP controlled job shop

We extend the concept of CONWIP control to a job shop setting, in which multiple products with distinct routings compete for the same set of resources. The problem is to determine the fixed overall WIP level and its allocation to product types (WIP mix) to meet a uniformly high customer service requirement for each product type. We formulate an optimization problem for an open queuing network model in which customer orders pull completed products from the system. Then, assuming heavy demand, we derive a throughput target for each product type in a closed queuing network and provide a simple heuristic to find a minimum total WJP and WIP mix that will achieve an operating throughput close to this target. In numerical examples, the WIP mix suggested by this approach achieves the customer service requirement with a relatively low total WIP     

Liver Disease: Induction,Progression, Immunological Mechanisms,and Therapeutic Interventions

The liver is an organ with impressive regenerative potential and has been shown to heal sizable portions after their removal. However, certain diseases can overstimulate its potential to self-heal and cause excessive cellular matrix and collagen buildup. Decompensation of liver fibrosis leads to cirrhosis, a buildup of fibrotic ECM that impedes the liver’s ability to efficiently exchange fluid. This review summarizes the complex immunological activities in different liver diseases, and how failure to maintain liver homeostasis leads to progressive fibrotic tissue development. We also discuss a variety of pathologies that lead to liver cirrhosis, such as alcoholic liver disease and chronic hepatitis B virus (HBV). Mesenchymal stem cells are widely studied for their potential in tissue replacement and engineering. Herein, we discuss the potential of MSCs to regulate immune response and alter the disease state. Substantial efforts have been performed in preclinical animal testing, showing promising results following inhibition of host immunity. Finally, we outline the current state of clinical trials with mesenchymal stem cells and other cellular and non-cellular therapies as they relate to the detection and treatment of liver cirrhosis.     

Reactive routing evaluation using modified 802.11a with realistic vehicular mobility

Realistic mobility dynamics and underlying PHY/MAC layer implementation affect real deployment of routing protocols in vehicular ad hoc network (VANET). Currently, dedicated short range communication devices are using wireless access in vehicular environment (WAVE) mode of operation, but now IEEE is standardizing 802.11p WAVE. This work presents an in-depth simulation-based analysis of two reactive routing protocols, i.e., dynamic source routing (DSR) and ad hoc on-demand distance vector (AODV) with modified IEEE 802.11a PHY/MAC layers (comparable to 802.11p) in modified VANET mobility models (freeway, stop sign, and traffic sign) in terms of load, throughput, delay, number of hops, and retransmission attempts. Results obtained using OPNET simulator show that in urban/highway mobility scenarios, AODV??s performance with forthcoming 802.11p at high bit rate would be better than DSR in terms of high throughput, less delay, and retransmission attempts. Moreover, this comprehensive evaluation will assist to address challenges associated with future deployment of routing protocols integrated upon devices with upcoming IEEE 802.11p, concerning specific macro-/micro-mobility scenarios.     

Assessment of dermal exposure to pesticide residues during re-entry

Currently, the determination of health risks to pesticide applicators from dermal exposure to these chemicals is assessed using either a concentrate of the compound or a relevant aqueous dilution. Neither of these conditions reflects a normal exposure of an individual when re-entering an area after pesticide application, that is, contact with dried residue of the diluted product on foliage. Methodology has therefore been developed to determine a relevant estimate of this potential dermal re-entry exposure from pesticide residues. Potential delivery platforms have been characterized for the transfer of pesticide residue to skin. Spin coating has been used to deposit uniform pesticide layers on to each platform. Five pesticides have been chosen to encompass a wide range of physicochemical properties: atrazine, 2,4-dichlorophenoxyacetic acid (2,4-D), chlorpyrifos, monocrotophos, and acetochlor. In vitro (Franz diffusion cell) experiments have been performed to monitor the transfer of these pesticides from the delivery platforms onto and through excised porcine skin. Parallel experiments were also conducted with aqueous pesticide dilutions for comparison, and a final in vivo measurement using ibuprofen (as a model compound) complemented the in vitro data. The results demonstrate that transfer of chemical residue onto and subsequently through the skin is dependent on the physical attributes of the residue formed. Thus, assessing dermal exposure to pesticides based on skin contact with either the chemical concentrate or a relevant aqueous dilution may incorrectly estimate the risk for re-entry scenarios.
