[Review of] Toni Morrison. Song of Solomon: The Flight of Afro-American Life

Song of Solomon can only be viewed as a tribute to the artistic and cultural genius of Ms. Toni Morrison. I, as reviewer and want-to-be-rich writer, am studious and intent throughout my reading of her novel. I am amazed, gratified and satisfied. I am fully amazed that she pulls it through; this wealth of characterization and plot. This is a novel of growing into manhood. It is at once the tale of man-to-man relationships and man-to-woman relationships in the Afro-American community where there is an essential struggle simply to be: There is in Song of Solomon mystery, romance and intrigue. The Song catalogues the fundamental struggle for integrity of the Black being in this American land. I am grateful, that Ms. Morrison does not enter into the fabric of this torn garment with stock-issue characters. I am thoroughly satisfied upon completion of the novel, that there is nothing left undone, there is no string untied. Song of Solomon is a masterpiece of fiction

A special unit for disruptive secondary school students : a social systems analysis : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Education at Massey University

This study is a qualitative description of the Hutt Valley Activity Centre, which is a special unit for disruptive secondary school students. The writer is the Director of this unit, and he applies the Getzels Guba social systems model to the data which is collected. The research is essentially concerned with the organisation and administration of the Activity Centre, and the model postulates that social behaviour in a school is affected by institutional expectations, group intentions and individual needs. These three aspects are developed more fully with the institutional element of the model describing the development of the Hutt Valley Activity Centre, the job descriptions of staff, administration and management and community resources and parental links. In the work group element, the following factors which influence the group dynamics are discussed: the composition of the group - the background and values of' the students, the referral of new students and assessment of students' progress, organisational procedures, and the Activity Centre programme. The individual element gives a descriptive case-study of two students who attended the Activity Cerntre. There is a chapter which describes a typical day in the life of an Activity Centre Director, with all the incidents based on what actually happened. The review of related literature provides a n nber of source references to special classes or units for disruptive secondary school students in New Zealand. and abroad. The concluding chapter gives a number of recommendations relating to the educational unit which is studied.. These include: the need for the Management Committee to include more representatives from community organisations, an increase in staffing, the need for more permanent tenure for the building which is occupied, for increased travel allowances to cover costs incurred by staff whilst on Activity Centre business, and an annual time allowance of up to eight days per annum to be allocated to the Activity Centre staff for the purpose of visiting organisations and departments related to the Centre and its students

Using an Online Sample to Estimate the Size of an Offline Population.

Online data sources offer tremendous promise to demography and other social sciences, but researchers worry that the group of people who are represented in online data sets can be different from the general population. We show that by sampling and anonymously interviewing people who are online, researchers can learn about both people who are online and people who are offline. Our approach is based on the insight that people everywhere are connected through in-person social networks, such as kin, friendship, and contact networks. We illustrate how this insight can be used to derive an estimator for tracking the digital divide in access to the Internet, an increasingly important dimension of population inequality in the modern world. We conducted a large-scale empirical test of our approach, using an online sample to estimate Internet adoption in five countries (n ≈ 15,000). Our test embedded a randomized experiment whose results can help design future studies. Our approach could be adapted to many other settings, offering one way to overcome some of the major challenges facing demographers in the information age

What Motivates Farms to Associate? The Case of Two Competing Czech Agricultural Associations

The study investigates determinants of affiliation with the two strongest associations in Czech agriculture. These represent Agricultural Association grouping large-scale enterprises and Association of Private Farmers, respectively. Our objective is to analyze whether associations with different types of members (large-scale enterprises vs. private farmers) experience different motives for joining or lapsing. Moreover, we investigate if there are characteristics of the associations' members which positively correlate to membership. The results imply that political lobbying is the main entry incentive for both large-scale enterprises and individual farmers. Informal information exchange is a more significant motivation for private farmers than for agricultural enterprises. To the question of who affiliates, we found that the probability of association membership of individual private farms significantly increases with employment of external workers and their commercial orientation, and the probability of association membership of large-scale agricultural enterprises significantly increases with the increasing share of livestock production on the total agricultural revenues and the increasing share of employee ownership.Associations, agricultural enterprises, Czech agriculture, selective incentives, individual farms, transition, Farm Management, D71, D72, D73, L14, L21, L22, C35,

On the calculation of the response of helicopters to control inputs

In the past few years, a number of studies have provided accurate flight test data for the control response of single rotor helicopters over a wide frequency range. These measured responses have been compared to theory in a number of studies. Various differences between theory and experiment appear in all of these studies. Some of these differences are examined. A quantitative explanation of one prominent difference associated with the contribution of the lag degree of freedom is provided. Areas for further investigation are suggested. The discussion is directed towards articulated rotor helicopters. Flight test data from the UH-60, CH-53, and AH-64 helicopters, much of it taken for the express purpose of evaluating the control response, correlation with theory, and the use of parameter identification methods, is considered. Results for flight conditions near hover are emphasized

Molecular collisions 21: Semiclassical approximation to atom-symmetric top rotational excitation

A distorted wave approximation to the T matrix for atom-symmetric top scattering was developed. The approximation is correct to first order in the part of the interaction potential responsible for transitions in the component of rotational angular momentum along the symmetry axis of the top. A semiclassical expression for this T matrix is derived by assuming large values of orbital and rotational angular momentum quantum numbers

Mineralogy and composition of Archean Crust, Greenland: A pilot study

The Portable Instant Display and Analysis Spectrometer (PIDAS) was taken to southwestern Greenland to investigate in situ the potential application of AVIRIS to estimate the mineralogy and composition of rocks exposed in Archean terranes. The goal was to determine the feasibility of using a high spectral resolution scanner to find and study pristine rocks, those that have not been altered by subsequent deformation and metamorphism. The application of AVIRIS data to the problems in Greenland is logical. However, before a costly deployment of the U-2 aircraft to Greenland is proposed, this study was undertaken to acquire the spectral data necessary to verify that mineralogical mapping in the environmental conditions found there is possible. Although field conditions were far from favorable, all of the major objectives of the study were addressed. One of the major concerns was that lichens would obscure the rock surfaces. It was found that the spectral signature of the lichens was distinct from the underlying rocks. Thus, a spectrum of a rock outcrop, with its partial cover of lichens, can be un-mixed into rock and lichen components. The data acquired during the course of this study supports the conclusion that areas of pristine Archean crust can be differentiated from that which has experienced low grade alteration associated with Proterizoic faulting

A complex network perspective on clinical science

Contemporary classification systems for mental disorders assume that abnormal behaviors are expressions of latent disease entities. An alternative to the latent disease model is the complex network approach. Instead of assuming that symptoms arise from an underlying disease entity, the complex network approach holds that disorders exist as systems of interrelated elements of a network. This approach also provides a framework for the understanding of therapeutic change. Depending on the structure of the network, change can occur abruptly once the network reaches a critical threshold (the tipping point). Homogeneous and highly connected networks often recover more slowly from local perturbations when the network approaches the tipping point, potentially making it possible to predict treatment change, relapse, and recovery. In this article, we discuss the complex network approach as an alternative to the latent disease model and its implications for classification, therapy, relapse, and recovery.R34 MH086668 - NIMH NIH HHS; R01 AT007257 - NCCIH NIH HHS; R21 MH101567 - NIMH NIH HHS; R34 MH099311 - NIMH NIH HHS; R21 MH102646 - NIMH NIH HHS; K23 MH100259 - NIMH NIH HHS; R01 MH099021 - NIMH NIH HH
