A model for a multifunctional teaching system

A Model for a Mul" "-A teaching system model that was incorporated into an operating system of a large computer is described. The model transferred control to the operating system to execute functions other than teaching, and then recovered control in order to resume teaching. The teaching system (ABAC-II) was written to run under the operating system (IBSYS) for the IBM 7044 Graphic System. Because the teaching system automatically terminated and reschecluled itself, a student studying a course presented at a cathode-ray display terminal could switch readily between student mode and programmer mode. During the latteb the full resources of the operating system (language processors, compilers, library and user's programs) were at his disposal. He could, for example, write, assemble, debug, and execute at the terminal a program written in any language processed by the operating system. A course could therefore include text material interleaved with programming problems which the student could solve without leaving the terminal. Exercises in simulation and gaming could also be provided. The implications of a teaching system with this degree of flexibility for industrial and executive training as well as academic education are discussed. In addition, the advantages of this type of system for computer programming and operation are also considered. In troduetlon It is axiomatic that a computer is a general purpose system that can be programmed to perform a number of functions. ()m~ of the functions of the computer that has gained considerable interest in recent years is that of teactting 14]. A number of teaching systems or course writers have been written that enaMe art author to write (ours{s for presentt~tion to students at terminals [3], and pr~liminary research indicates that computer-assisted instruction can present a course in less time than other methods of instruction [1 ]. The typical teaching system is a stand-alone system designed for a small computer. Since the system retains control of the computer during execution, only functions which have been speeificaJly programmed into the teaching system can be carried out by the student. For example, if language processing is desired, a language processor nmst be written for the teaching system. Adding a number of functions to make the teaching system more flexible, i.e., capable ot more than just presenting course text, would require extensive programming. Moreover, the number of functions that could be added would be limited by the capacity of the computer. On the other hand, …
Hearts of Steel

This article looks at the way Arab male and female journalists in pan-Arab media negotiate their journalistic ethics with the aim of boosting their professional image while adding credibility to their news. Drawing on several examples of these male and female journalists, I seek to show how women adopt an un-emotional style when reporting news of pain and suffering, while male journalists emotionally engage with this type of news. The analysis draws on extensive interviews with male and female Arab journalists in pan-Arab media which are scattered inside and outside the Arab region. The discussion is informed by the current debate around detachment versus attachment in news reporting as well as the feminist media debate about the distinction between feminine and masculine values in mediating suffering.
Accuracy Assessment of Digital Surface Models Based on WorldView-2 and ADS80 Stereo Remote Sensing Data

Digital surface models (DSMs) are widely used in forest science to model the forest canopy. Stereo pairs of very high resolution satellite and digital aerial images are relatively new and their absolute accuracy for DSM generation is largely unknown. For an assessment of these input data two DSMs based on a WorldView-2 stereo pair and a ADS80 DSM were generated with photogrammetric instruments. Rational polynomial coefficients (RPCs) are defining the orientation of the WorldView-2 satellite images, which can be enhanced with ground control points (GCPs). Thus two WorldView-2 DSMs were distinguished: a WorldView-2 RPCs-only DSM and a WorldView-2 GCP-enhanced RPCs DSM. The accuracy of the three DSMs was estimated with GPS measurements, manual stereo-measurements, and airborne laser scanning data (ALS). With GCP-enhanced RPCs the WorldView-2 image orientation could be optimised to a root mean square error (RMSE) of 0.56 m in planimetry and 0.32 m in height. This improvement in orientation allowed for a vertical median error of −0.24 m for the WorldView-2 GCP-enhanced RPCs DSM in flat terrain. Overall, the DSM based on ADS80 images showed the highest accuracy of the three models with a median error of 0.08 m over bare ground. As the accuracy of a DSM varies with land cover three classes were distinguished: herb and grass, forests, and artificial areas. The study suggested the ADS80 DSM to best model actual surface height in all three land cover classes, with median errors <1.1 m. The WorldView-2 GCP-enhanced RPCs model achieved good accuracy, too, with median errors of −0.43 m for the herb and grass vegetation and −0.26 m for artificial areas. Forested areas emerged as the most difficult land cover type for height modelling; still, with median errors of −1.85 m for the WorldView-2 GCP-enhanced RPCs model and −1.12 m for the ADS80 model, the input data sets evaluated here are quite promising for forest canopy modelling.
Sparse Time-Frequency Decomposition for Multiple Signals with Same Frequencies

In this paper, we consider multiple signals sharing same instantaneous frequencies. This kind of data is very common in scientific and engineering problems. To take advantage of this special structure, we modify our data-driven time-frequency analysis by updating the instantaneous frequencies simultaneously. Moreover, based on the simultaneously sparsity approximation and fast Fourier transform, some efficient algorithms is developed. Since the information of multiple signals is used, this method is very robust to the perturbation of noise. And it is applicable to the general nonperiodic signals even with missing samples or outliers. Several synthetic and real signals are used to test this method. The performances of this method are very promising.

Maltose/Maltodextrin System of Escherichia coli: Transport, Metabolism, and Regulation

SUMMARY The maltose system of Escherichia coli offers an unusually rich set of enzymes, transporters, and regulators as objects of study. This system is responsible for the uptake and metabolism of glucose polymers (maltodextrins), which must be a preferred class of nutrients for E. coli in both mammalian hosts and in the environment. Because the metabolism of glucose polymers must be coordinated with both the anabolic and catabolic uses of glucose and glycogen, an intricate set of regulatory mechanisms controls the expression of mal genes, the activity of the maltose transporter, and the activities of the maltose/maltodextrin catabolic enzymes. The ease of isolating many of the mal gene products has contributed greatly to the understanding of the structures and functions of several classes of proteins. Not only was the outer membrane maltoporin, LamB, or the phage lambda receptor, the first virus receptor to be isolated, but also its three-dimensional structure, together with extensive knowledge of functional sites for ligand binding as well as for phage λ binding, has led to a relatively complete description of this sugar-specific aqueous channel. The periplasmic maltose binding protein (MBP) has been studied with respect to its role in both maltose transport and maltose taxis. Again, the combination of structural and functional information has led to a significant understanding of how this soluble receptor participates in signaling the presence of sugar to the chemosensory apparatus as well as how it participates in sugar transport. The maltose transporter belongs to the ATP binding cassette family, and although its structure is not yet known at atomic resolution, there is some insight into the structures of several functional sites, including those that are involved in interactions with MBP and recognition of substrates and ATP. A particularly astonishing discovery is the direct participation of the transporter in transcriptional control of the mal regulon. The MalT protein activates transcription at all mal promoters. A subset also requires the cyclic AMP receptor protein for transcription. The MalT protein requires maltotriose and ATP as ligands for binding to a dodecanucleotide MalT box that appears in multiple copies upstream of all mal promoters. Recent data indicate that the ATP binding cassette transporter subunit MalK can directly inhibit MalT when the transporter is inactive due to the absence of substrate. Despite this wealth of knowledge, there are still basic issues that require clarification concerning the mechanism of MalT-mediated activation, repression by the transporter, biosynthesis and assembly of the outer membrane and inner membrane transporter proteins, and interrelationships between the mal enzymes and those of glucose and glycogen metabolism.

Effects of Part-Task Training on Memory Set Unitization and Retention of Memory-Dependent Skilled Search

Two experiments were conducted to examine the effects of part-task training on the acquisition and retention of a memory-dependent skill. Participants received extensive practice on a semantic category, memory/visual search task in one of three training conditions. To assess the effects of part-task training on memory element unitization, subjects trained on one third, one half, or all of the memory set elements during any given training session. Transfer tests requiring whole-task performance provided one index of training effectiveness. The results suggest that consistent memory sets can be unitized even if part-task training is used. Indeed, part-task training was as effective as whole-task training when immediate transfer was assessed. Part-task training produced retention performance equivalent to whole-task training when retention performance was determined by both target and distract or learning. Retention performance was superior for part-task training compared with whole-task training when performance was based on only target learning.
Folterverbot oder "Rettungsfolter"? Urteile Jugendlicher über Moral, Menschenrechte und Rechtsstaatlichkeit angesichts eines realen moralischen Dilemmas

Das absolute Folterverbot gehort zu den Grundlagen des demokratischen Rechtsstaats, im Zuge der Diskussion uber die "Rettungsfolter" ist es in jungster Zeit jedoch stark relativiert worden. Der Beitrag untersucht anhand eines realen Falls, wie Jugendliche das Dilemma interpretieren und inwieweit sie dabei menschenrechtliche und rechtsstaatliche Aspekte beachten. Erwartet wurde, dass mit der Fahigkeit zu systemisch- transpersonalem Urteilen die Ablehnung der Folter und der Rekurs auf Menschenrechte und Rechtsstaatlichkeit zunehmen. Die Befunde bestatigen diese These, zeigen aber auch starke kontextspezifische Variationen und eine hohe Diskrepanz zwischen allgemeiner und kontextueller Beurteilung der Menschenrechte. (DIPF/Orig.) The absolute prohibition of torture is one of the fundamental principles of the democratic state under the rule of law; however, in the course of the recent debate on "rescue torture", it has been qualified considerably. On the basis of a real case, the authors investigate how adolescents interpret the dilemma and in how far they take aspects of human rights and rule of law into consideration. It was expected that, with the ability to make systemic-transpersonal judgments, the rejection of torture and the appeal to human rights and rule of law would increase. The results confirm this hypothesis; however, they also reveal strong context-specific variations and a high discrepancy between a general and a contextual assessment of human rights. (DIPF/Orig.)
A Model Independent S/W Framework for Search-Based Software Testing

In Model-Based Testing (MBT) area, Search-Based Software Testing (SBST) has been employed to generate test cases from the model of a system under test. However, many types of models have been used in MBT. If the type of a model has changed from one to another, all functions of a search technique must be reimplemented because the types of models are different even if the same search technique has been applied. It requires too much time and effort to implement the same algorithm over and over again. We propose a model-independent software framework for SBST, which can reduce redundant works. The framework provides a reusable common software platform to reduce time and effort. The software framework not only presents design patterns to find test cases for a target model but also reduces development time by using common functions provided in the framework. We show the effectiveness and efficiency of the proposed framework with two case studies. The framework improves the productivity by about 50% when changing the type of a model.
Design of the randomized, Phase III, QUAZAR AML Maintenance trial of CC-486 (oral azacitidine) maintenance therapy in acute myeloid leukemia

Older patients with acute myeloid leukemia (AML) have worse rates of complete remission and shorter overall survival than younger patients. The epigenetic modifier CC-486 is an oral formulation of azacitidine with promising clinical activity in patients with AML in Phase I studies. The Phase III, randomized, double-blind, placebo-controlled QUAZAR AML Maintenance trial (CC-486-AML-001) examines CC-486 maintenance therapy (300 mg/day for 14 days of 28-day treatment cycles) for patients aged ≥55 years with AML in first complete remission. The primary end point is overall survival. Secondary end points include relapse-free survival, safety, health-related quality of life and healthcare resource utilization. This trial will investigate whether CC-486 maintenance can prolong remission and improve survival for older patients with AML.

Canonical Transient Receptor Potential (TRPC) 1 Acts as a Negative Regulator for Vanilloid TRPV6-mediated Ca2+ Influx*

Background: Heteromerization of TRP family members can affect their physiological and biophysical properties. Results: TRPV6 and TRPC1 associate via their ankyrin-like repeat domains. Co-expression of TRPV6 and TRPC1 reduced TRPV6 expression in the plasma membrane, and hence reduces TRPV6 influx currents. Conclusion: TRPC1 acts as negative regulator on TRPV6 mediated Ca2+ signaling. Significance: We show here a novel regulation in TRPV6 activity by formation of heterocomplexes with TRPC1. TRP proteins mostly assemble to homomeric channels but can also heteromerize, preferentially within their subfamilies. The TRPC1 protein is the most versatile member and forms various TRPC channel combinations but also unique channels with the distantly related TRPP2 and TRPV4. We show here a novel cross-family interaction between TRPC1 and TRPV6, a Ca2+ selective member of the vanilloid TRP subfamily. TRPV6 exhibited substantial co-localization and in vivo interaction with TRPC1 in HEK293 cells, however, no interaction was observed with TRPC3, TRPC4, or TRPC5. Ca2+ and Na+ currents of TRPV6-overexpressing HEK293 cells are significantly reduced by co-expression of TRPC1, correlating with a dramatically suppressed plasma membrane targeting of TRPV6. In line with their intracellular retention, remaining currents of TRPC1 and TRPV6 co-expression resemble in current-voltage relationship that of TRPV6. Studying the N-terminal ankyrin like repeat domain, structurally similar in the two proteins, we have found that these cytosolic segments were sufficient to mediate a direct heteromeric interaction. Moreover, the inhibitory role of TRPC1 on TRPV6 influx was also maintained by expression of only its N-terminal ankyrin-like repeat domain. Our experiments provide evidence for a functional interaction of TRPC1 with TRPV6 that negatively regulates Ca2+ influx in HEK293 cells.
On-demand reliable medium access in sensor networks

A wireless sensor network typically consists of a dense deployment of sensor nodes to achieve higher resolution and better network coverage. Having a dense network increases the fault-tolerance and robustness of the system. However, if not properly handled, it can lead to more collisions during transmission and also network congestion. Furthermore, wireless communication is inherently unpredictable and error-prone. Hence, it is imperative to design an efficient medium access control (MAC) protocol that facilitates guaranteed delivery of data over unreliable wireless links. In this paper, we have designed an on-demand reliable MAC (RMAC) protocol that enables timely delivery of data. We have demonstrated its superior performance over existing reliability-enforcing approaches in terms of reliability, latency, scalability and energy-efficiency
Improved Transient Response via Discrete Event Reference Control

We consider a new approach to improve the performance of reference tracking problems for closed loop stabilized continuous linear systems through the application of a sequence of reference signals initiated by the occurrence of a discrete event. By means of the internal model principle, we show that a change in the reference signal is equivalent to implementing an instantaneous change via the choice of a decision vector in the state of the reference model. The analysis of the characteristics of the resulting discrete event reference control (DERC) system is then shown to be equivalent to the analysis of a linear impulsive system. Conditions for asymptotic stability and convergence of the output tracking error for a DERC system are then expressed in term of conditions on the decision vector. In particular, it is shown how to choose the decision vectors so that a DERC system has a deadbeat tracking error response. Finally, conditions are also derived which guarantee that the DERC system has an improved transient performance compare with a conventional reference tracking system.
