TL;DR: In this article, the authors examine the concept of formalized dissent and discuss how this principle can be applied to the decision making process of executives in order to improve their decisions, and suggest that a corporate devil's advocate could play a significant role in an organization, providing constructive criticism in an institutionalized manner that would depersonalize the idea of having one's work criticized.
Abstract: In this article the authors examine the concept of formalized dissent and discuss how this principle can be applied to the decision making process of executives in order to improve their decisions. They examine various forms of formalized dissent such as the Catholic Church's use of a devil's advocate in the selection of an individual for sainthood as well as the work of consumer advocates who bring negative product information into public view. They suggest that a corporate devil's advocate could play a significant role in an organization, providing constructive criticism in an institutionalized manner that would depersonalize the idea of having one's work criticized. They note that corporate decisions can have significant results and therefore reaching optimal decisions is invaluable.

TL;DR: In this paper, the authors simplify the concepts of the zoom transform and remove some of the restrictions assumed by Yip; i.e., the total number of points need not be a power of 2.
Abstract: A recent paper by Yip discussed the zoom transform as derived from the defining equation of the FFT. This paper simplifies the concepts and removes some of the restrictions assumed by Yip; ie., the total number of points need not be a power of 2. The technique is based on first specifying the desired center frequency, bandwidth, and frequency resolution. The signal is then sampled, modulated, and lowpass filtered. This result is purposely aliased, then transformed using an FFT algorithm. The result is an M-point frequency spectra of the desired bandwidth centered about the center frequency with a higher degree of resolution than could be directly obtained using an M-point transform.

TL;DR: This paper considers the problem of optimizing spatial frequency domain filters for detecting a class of edges in images and shows that the optimal filter represents the Laplacian operator in image space followed by a low pass filter with a cutoff frequency.
Abstract: Edge detection and enhancement are required in a number of important image processing applications. In this paper we consider the problem of optimizing spatial frequency domain filters for detecting a class of edges in images. The filter is optimum in that it produces maximum energy in the vicinity of the location of the edge for a given spatial resolution I and the bandwidth Ω. We show that the filter transfer function can be specified in terms of the prolate spheroidal wavefunctions for a given space–bandwidth product IΩ. Further we show that for values of IΩ less than 2, the optimal filter represents the Laplacian operator in image space followed by a low pass filter with a cutoff frequency Ω.

TL;DR: In this article, a possible study that can be immediately implemented to test the probability of identifying couples who might be at increased risk for experiencing the tragedy of sudden infant death syndrome (SIDS) is presented.
Abstract: This letter is directed to those persons who are conducting research in sudden infant death syndrome (SIDS). Dr. Tonkin9s anatomical evidence implicating pharyngeal relaxation during rapid eye movement (REM) sleep as a cause for SIDS is an important contribution to the literature (55:650, May 1975). Her work suggests a possible study that can be immediately implemented to test the probability of identifying couples who might be at increased risk for experiencing the tragedy of SIDS.

TL;DR: The present retrospective study demonstrates that the currently observed increased gene frequency among these formerly endogamous, highly fecund people is most probably a result of genetic drift.
Abstract: Tay‐Sachs disease is a recessively inherited, invariably lethal, degenerative neurological disorder caused by a lack of hexoaminidase‐A. It is a hundred times more prevalent among the American‐born descendants of the East European Ashkenazim Jews than among any other people in the world. The present retrospective study demonstrates that the currently observed increased gene frequency among these formerly endogamous, highly fecund people is most probably a result of genetic drift. Unique and drastic population contractive and expansion phases are documented to deduce the formation of numerous founder populations which were scattered throughout Eastern Europe by the nineteenth century. The subsequent mass familial migrations to the United States, coupled with the cultural practices of the immigrant generation, greatly enhanced the chances for heterozygote carriers to marry each other. Even if some form of selection were operative in the past, the concatenation of unique cultural events provides con...

TL;DR: In this paper, two dimensional wind tunnel tests were conducted for the GA(W)-2 airfoil section with: 20% aileron, 25% slotted flap; 30% Fowler flap, and 10% slot-lip spoiler.
Abstract: Two dimensional wind tunnel tests were conducted for the GA(W)-2 airfoil section with: 20% aileron, 25% slotted flap; 30% Fowler flap, and 10% slot-lip spoiler. All tests were conducted at a Reynolds number of 2,200,000 and a Mach Number of 0.13. In addition to force measurements, tuft studies were conducted for the slotted and Fowler flap configurations. Aileron and spoiler hinge moments were obtained by integration of surface pressure measurements. Tests results show that a value of 3.82 was obtained with 30% Fowler flap. Aileron control effectiveness and hinge moments were similar to other airfoils. The slot-lip spoiler provided powerful, positive roll control at all flap settings.
TL;DR: In this article, extensive pressure and velocity surveys of the pre-and post-separated regions on the airfoil and the associated wake are presented. And the results indicate steep gradients of displacement thickness, momentum thickness, shape factor, and the separation streamline from the point of separation to the trailing edge of the air foil.
Abstract: Detailed measurements of flow fields associated with low-speed turbulent boundary layers have been made for the 17% thick GA(W)-1 airfoil section at nominal angles of attack of 10, 14, and 18 deg; Reynolds number 2.2 million; and Mach number 0.13. The data include extensive pressure and velocity surveys of the pre- and post-separated regions on the airfoil and the associated wake. Integrated boundary-layer characteristics, including regions of separation on the airfoil, are also presented. The results indicate steep gradients of displacement thickness, momentum thickness, shape factor, and the separation streamline from the point of separation to the trailing edge of the airfoil. The present tests reveal that the region of flow reversal terminates within a suprisingly short distance of less than 20% chord downstream from the trailing edge for the test range of angle of attack.

TL;DR: In this article, the GA(W)-1 airfoil with a 0.30 c Fowler flap deflected 40 degrees at angles of attack of 2.7 deg, 7.7 degrees, and 12.8 degrees at a Reynolds number 2.2 million and a Mach number of 0.13.
Abstract: Measurements of flow fields with low speed turbulent boundary layers were made for the GA(W)-1 airfoil with a 0.30 c Fowler flap deflected 40 deg at angles of attack of 2.7 deg, 7.7 deg, and 12.8 deg, at a Reynolds number of 2.2 million, and a Mach number of 0.13. Details of velocity and pressure fields associated with the airfoil flap combination are presented for cases of narrow, optimum and wide slot gaps. Extensive flow field turbulence surveys were also conducted employing hot-film anemometry. For the optimum gap setting, the boundaries of the regions of flow reversal within the wake were determined by this technique for two angles of attack. Local skin friction distributions for the basic airfoil and the airfoil with flap (optimum gap) were obtained using the razor blade technique.

TL;DR: This new algorithm is designed to remove the requirement for transposition, thereby, greatly increasing the speed of the process, which is extremely valuable on small disc based computers.
Abstract: Conventional two dimensional fast Fourier transforms become very slow if the size of the matrix becomes too large to be contained in memory. This is due to the transposition of the matrix that is required. This new algorithm is designed to remove the requirement for transposition, thereby, greatly increasing the speed of the process. This algorithm is extremely valuable on small disc based computers.
TL;DR: In this article, a hierarchical factor solution was obtained for intercorrelations among the 10 regular WISC-R subtests for 169 children and adolescents referred to a community agency for assessment, which indicated an ability hierarchy composed of a strong general (g) factor and two sub-general factors corresponding to the spatial-perceptual (k:m) and verbal-educational (v:ed) parameters of Vernon's (1950) structural paradigm.
Abstract: A hierarchical factor solution was obtained for intercorrelations among the 10 regular WISC-R subtests for 169 children and adolescents referred to a community agency for assessment. This sample was predominantly rural but quite heterogeneous with respect to age, ability, and type of referral problem. The findings indicated an ability hierarchy composed of a strong general (g) factor and two sub-general factors corresponding to the spatial-perceptual (k:m) and verbal-educational (v:ed) parameters of Vernon's (1950) structural paradigm.

TL;DR: In this paper, the magnetic and thermal properties of a stainless steel (AISI 310S) and an Inconel superalloy (X 750) have been measured at cryogenic temperatures, and in most cases up to room temperature.
Abstract: Some magnetic and thermal properties of a stainless steel (AISI 310S) and an Inconel superalloy (X750) have been measured at cryogenic temperatures, and in most cases up to room temperature. The physical-property determinations were undertaken as part of a comprehensive investigation of the engineering properties of cryogenic structural materials applicable to superconducting machinery, i.e., machinery incorporating superconductive components. The alloys, whose properties are to be discussed here, were selected as candidates for advanced superconducting generator applications. Indeed, they have already been used in the construction of certain components of an experimental alternator currently under development. The alloys discussed below are categorized in terms of various melting practices and heat treatments with the codes corresponding to these conditions being defined in Table I. Further details regarding the procurement and metallurgical properties of these alloys are available elsewhere [1].
TL;DR: In this paper, the Cutler-Mott model was modified for magnetic effects by von Moln\'ar, Holtzberg, Penney, and their associates, and measured values of $\ensuremath{rho}$, ${R}_{H}$, $\enuremath{\alpha}$, and ''ensure-math{kappa}$'' were reported on single-crystal samples of the defect lattice structure.
Abstract: Measured values of $\ensuremath{\rho}$, ${R}_{H}$, $\ensuremath{\alpha}$, and $\ensuremath{\kappa}$ are reported on single-crystal samples of ${\mathrm{Nd}}_{2}$${\mathrm{S}}_{3}$, ${\mathrm{Gd}}_{2}$${\mathrm{S}}_{3}$, and ${\mathrm{Dy}}_{2}$${\mathrm{S}}_{3}$ containing excess rare earth in the defect lattice structure. Measurements cover the temperature range between roughly 7 and 1000 K, and an excess rare-earth composition range between 0.1 and 0.7 wt%. Data can be interpreted in terms of the Cutler-Mott model modified for magnetic effects by von Moln\'ar, Holtzberg, Penney, and their associates. Above 100 K, alloy scattering appears dominant. At lower temperatures the transport mechanism favors a hopping process for localized electrons in a magnetically ordered lattice.
TL;DR: In this paper, power series expansions of quantum-mechanical potential surfaces for H2O and LiH2 are generated using conventional valence displacement coordinates and alternative distance and angle.
Abstract: Power series expansions of quantum-mechanical potential surfaces for H2O and LiH2 are generated using conventional valence displacement coordinates and alternative distance [(r-r e)/r] and angle [(sin (θ/2) — sin (θe/2))/sin (θe/2)] variables Power series in the new variables are demonstrated to be superior in terms of the quality of the fit to the energygeometry data, predicted equilibrium geometry and energy, and stability of expansion coefficients
TL;DR: In the fourth act of Michaelmas Term, Quomodo, a crafty woolen draper, is putting the finishing touches on his successful attempt to cozen young Richard Easy out of his inheritance as discussed by the authors.
Abstract: S the fourth act of Michaelmas Term begins, Quomodo, a crafty woolen draper, is putting the finishing touches on his successful w attempt to cozen young Richard Easy out of his inheritance. But like so many of Middleton’s tricksters Quomodo is never satisfied; he initiates one last plot that ironically brings about his own downfall and Easy’s recovery. Worried that his son will prove as foolish as the gallant he has just gulled, Quomodo feigns death in order to “note the condition of all. . . . [Blecause I see before mine eyes that most of our heirs prove notorious rioters after our deaths . . . why should not I oppose ’em now, and break Destiny of her custom?” (1v.i.87-88,94-95, i i i ) . l Quomodo, however, is unable to oppose “Destiny.” His son does become a “notorious rioter,” Quomodo loses everything, and Easy regains the lands he had earlier let slip through his fingers. Critics unanimously condemn this sudden reversal in the fortunes of Middleton’s clever draper and his former victim. Richard Barker, for example, complains that Middleton weakens “his most interesting character [Quomodo],” and his point is reinforced by Ruby Chatterji: “Thematic unity has not found its dramatic correlative in consistent characterization.”2 Richard Levin perhaps best sums up the problems that seem to be inherent in Middleton’s conclusion: “We are evidently expected to side with Easy and enjoy his triumph; and that is the usual response in plays belonging to

TL;DR: In this article, wind tunnel force and pressure tests were conducted for the GA(W)-1 airfoil equipped with a 20% aileron and 30% Fowler flap.
Abstract: Wind tunnel force and pressure tests were conducted for the GA(W)-1 airfoil equipped with a 20% aileron, and pressure tests were conducted with a 30% Fowler flap. All tests were conducted at a Reynolds number of 2.2 and a Mach number of 0.13. The aileron provides control effectiveness similar to ailerons applied to more conventional airfoils. Effects of aileron gaps from 0% to 2% chord were evaluated, as well as hinge moment characteristics. The aft camber of the GA(W)-1 section results in a substantial up-aileron moment, but the hinge moments associated with aileron deflection are similar to other configurations. Fowler flap pressure distributions indicate that unseparated flow is achieved for flap settings up to 40 deg., over a limited angle of attack range. Theoretical pressure distributions compare favorably with experiments for low flap deflections, but show substantial errors at large deflections.
TL;DR: This paper derives a form of Parzen estimator which uses a data dependent smoothing matrix and a Gaussian weighting function and it is established that the estimator is asymptotically consistent.
TL;DR: The study investigated the relative efficiency of the Bender and MPD as assessors of achievement-related errors in visual-motor perception to suggest that psychologists engaged in the assessment of older children seriously should consider adding the MPD to their assessment battery.
Abstract: The study investigated the relative efficiency of the Bender and MPD as assessors of achievement-related errors in visual-motor perception. Clinical experience with these two tests suggests that beyond first grade the MPD is more sensitive than the Bender for purposes of measuring deficits in visual-motor perception that interfere with effective classroom learning. The sample was composed of 153 third-grade children from two upper-middle-class elementary schools in a surburban school system in central Ohio. For three of the four achievement criteria, the results were clearly congruent with the hypothesis stated above. That is, SpCD errors from the MPD not only showed significantly higher negative rs with the criteria (reading vocabulary, reading comprehension, and mathematics computation) than Koppitz errors from the Bender, but also accounted for a much higher proportion of the variance in these criteria. Thus, the findings suggest that psychologists engaged in the assessment of older children seriously should consider adding the MPD to their assessment battery.
TL;DR: In this article, the Cebeci-Smith boundary-layer method is used to estimate the separation point for both laminar and turbulent flows by using zero-c/ criterion.
Abstract: T HE Cebeci-Smith boundary-layer method is a numerical method which is found to give results which are satisfactory for most engineering problems. There is nothing special about it. The numerical scheme is an accurate and economical one, and the algebraic turbulence model has been correlated with available experimental data to produce reasonable results. This method is not expected to handle both the separation location and the resulting pressure distribution at separation, since such a capability will require an iteration between an inviscid and a viscous flow. What I mentioned in my paper was our observation of calculating the separation point by this method for a given pressure distribution. I am sure Mr. Goldschmied will agree with me, that flow separation changes the pressure distribution. So, to what extent the given inviscid pressure distribution for a flow with separation can be used is questionable. On the other hand, in using an inviscid pressure distribution I feel that one can locate the separation point for both laminar and turbulent flows by using zero-c/ criterion. Furthermore, I find it ridiculous to accept that the cf=Q criterion for separation depends on chordwise location only. Actually, neither the chordwise location nor the pressure drop should be used directly to predict separation. Separation is the result of boundary-layer development and occurs when the wall shear goes to zero. Chordwise location and pressure drop at separation are results and not prerequisites for predicting separation. Mr. Goldschmied ^claims that he and his associates have developed a method for predicting pressure distributions with massive separation. However, upon close examination, I find their method to be another self-predicting empirical correlation. Because the mystic Goldschmied separation criterion fails to predict the true separation pressure level, he adds a correction which also changes the separation location. So far, so good, but then he proceeds to test his method on cases which formed the basis for his empirical correlation! No independent test cases were presented. What else can one expect but good agreement? This is a good example of a circular argument.
TL;DR: In this paper, the authors attempted to determine if relationships exist between certain important sociodemographic variables and community satisfaction in a British new town and found significant relationships (p <.05) were found for several variables.
Abstract: Summary This study attempted to determine if relationships exist between certain important sociodemographic variables and community satisfaction in a British new town. A randomly selected sample of 220 adult residents of a British new town were administered a questionnaire containing 60 community satisfaction items and a personal data section. A Likert scale was then constructed and used as the dependent variable in regression and tabular analyses. Significant relationships (p < .05) were found for several variables. The results were discussed in relation to the “settling-in” period subsequent to migration and urban planning policy.
TL;DR: In this article, the authors focus on typology construction as a focal technique in the analysis of crime and crime control systems from a world perspective, and the relationship between theories and typologies is discussed.
Abstract: This article focuses on typology construction as a focal technique in the analysis of crime and crime control systems from a world perspective. The relationship between theories and typologies is discussed. The author stresses the structure of theory when the world is defined as a system which includes sub-systems. Theoretical schemes depend on the existence of world sub-system typologies. Crime typologies and legal system typologies are needed because the formulation of a world law will be affected by the existence of typologies which clarify the similarities and dissimilarities of world legal systems.
