Can creative destruction be destroyed? Military IR&D and destruction along the value-added chain

We elaborate a supply chain innovation matrix that can be applied to both commercial and military supply chains. By shifting the analysis from a focal firm to industry structure, we argue that the market structure of the entire supply chain functions as a major moderating variable in determining both the timing and adoption of innovations, both for commercial and military markets. We extend work on supply chain resource dependency by drawing a distinction between market-structure-induced resource dependency and supplier over-reliance on a customer in a competitive market. This has policy implications for the organization of military industrial research and development (IR&D). Joint service research and development (Jointness) will certainly bring about innovation, but it will be incremental, reinforcing established military hierarchies. Policy makers may need to add this probable consequence when comparing Jointness and inter-service rivalry. The cost savings inherent in Jointness may unwittingly sustain a military force unready for fighting the next war.     

An afterschool intervention program for educationally disadvantaged young children

The research investigated the premise that if educationally disadvantaged children experience increased instructional time combined with an educational setting that is sensitive to their culture and that provides perceptions of control, enhanced achievement and interest in learning will result. The research setting was the Hilltop Emergent Literacy Project (HELP), an afterschool educational program serving poor, mostly African American five- to nine-year-olds (kindergarten to third grade) who reside in a subsidized apartment complex. A treatment group of 12 kindergartners was compared to a control group of 12 kindergartners. In the spring of kindergarten, the treatment group was outperforming the control group on standardized test scores, but both groups were below national norms. In the spring of first grade, the treatment group was still outperforming the control group and was above national norms in some areas. Report card data and qualitative indicators also provide evidence of the effectiveness of the program.We thank the Hilltop Emergent Literacy Project (HELP) head teachers Teresa Bunge and Diana Reamsnyder, the HELP students, and the many graduate and undergraduate students who have served at HELP. This program was partially funded through grants from the University of Toledo, Ohio Board of Regents, General Mills Foundation, and Toledo Public Schools.     

Periodical Time in the Nineteenth Century

This article traces the growth of newspapers for African readers in Southern Rhodesia. It focuses primarily on the role played by South African investors in launching newspapers for the Africans. It further looks at the transformation of these newspapers from mouthpieces of the colonial government to being mouthpieces of African Nationalists. Issues of funding as well as reactions by Africans will be addressed. The article also attempts to discuss the impact of these newspapers on both the readers and the politicians.     

In pursuit of the effective neighborhood information system: User-friendliness and training

The goal of this research is to address the effectiveness of Neighborhood Information Systems (NIS) as an Information Technology (IT) tool in assisting community development. NISs are hybrid applications of Geographical Information Systems (GIS) and web technologies that provide demographic, social, and economic information to community stakeholders. Government agencies, nonprofit organizations, and community organizations engage in decision-making process for community development, and NISs are designed to help information-sharing and effective and participatory decision-makings for community development stakeholders.     

The role of effort in moderating the anxiety – performance relationship: Testing the prediction of processing efficiency theory in simulated rally driving

Abstract

We tested some of the key predictions of processing efficiency theory using a simulated rally driving task. Two groups of participants were classified as either dispositionally high or low anxious based on trait anxiety scores and trained on a simulated driving task. Participants then raced individually on two similar courses under counterbalanced experimental conditions designed to manipulate the level of anxiety experienced. The effort exerted on the driving tasks was assessed though self-report (RSME), psychophysiological measures (pupil dilation) and visual gaze data. Efficiency was measured in terms of efficiency of visual processing (search rate) and driving control (variability of wheel and accelerator pedal) indices. Driving performance was measured as the time taken to complete the course. As predicted, increased anxiety had a negative effect on processing efficiency as indexed by the self-report, pupillary response and variability of gaze data. Predicted differences due to dispositional levels of anxiety were also found in the driving control and effort data. Although both groups of drivers performed worse under the threatening condition, the performance of the high trait anxious individuals was affected to a greater extent by the anxiety manipulation than the performance of the low trait anxious drivers. The findings suggest that processing efficiency theory holds promise as a theoretical framework for examining the relationship between anxiety and performance in sport.     

Success in the Dutch Music Festival Market: The Role of Format and Content

Nowadays, music festivals are very important for generating revenue streams in the music industry. However, studies on what makes music festivals a success are scant. In this article, a conceptual model to explain the success of music festivals is introduced and tested. Such a model seems pressing now that competition in the music festival industry is increasing. Our conceptual model includes variables that are under the control of music festival organizers, namely format and content characteristics. The content features include scope of the audience, lineup, age, and having a theme or message. Budget, ticket price, location, and having a maximum visitor capacity make up the format features. The model is tested with data from 47 music festivals in the Netherlands. The results show that relatively newer festivals can achieve good growth in terms of visitor attendance, especially if they have a narrow scope (niche). Interestingly, this is true for both large and small festivals. Our findings are important with respect to music festival diversity and choice for audiences, which may be at risk due to increasing competition. The fact that several festivals have a capacity constraint seems to be beneficial for diversity as well. Interestingly, budgets (and star lineup and ticket price), theme, and location are largely nonsignificant predictors of success.     

Coaching psychology: an approach to practice for educational psychologists

Coaching psychology is a distinct sub-discipline of academic and applied psychology that focuses on the enhancement of performance, development and well-being in the broader population. Applied in educational contexts, the practice of coaching psychology has the potential to have a positive impact by supporting children and adults to achieve enhanced standards of functioning and well-being. It therefore represents a way in which educational psychologists (EPs) might elect to diversify their practice. However, EPs are disproportionately under-represented in the development of this emerging field. This article charts the birth and evolution of contemporary coaching psychology, and presents a case study illustrating the application of this methodology in a school context. Suggestions are given regarding professional development activities that might be undertaken by EPs seeking to develop coaching psychology as a strand of their practice.     

Effects of load mass carried in a backpack upon respiratory muscle fatigue

Purpose: The purpose of this study was to investigate whether loads carried in a backpack, with a load mass ranging from 0 to 20?kg, causes respiratory muscle fatigue. Methods: Eight males performed four randomised load carriage (LC) trials comprising 60?min walking at 6.5?km?h^?1 wearing a backpack of either 0 (LC₀), 10 (LC₁₀), 15 (LC₁₅) or 20?kg (LC₂₀). Inspiratory (P_Imax) and expiratory (P_Emax) mouth pressures were assessed prior to and immediately following each trial. Pulmonary gas exchange, heart rate (HR), blood lactate and glucose concentration and perceptual responses were recorded during the first and final 60?s of each trial. Results: Group mean P_Imax and P_Emax were unchanged following 60-min load carriage in all conditions (p?>?.05). There was an increase over time in pulmonary gas exchange, HR and perceptions of effort relative to baseline measures during each trial (p?p?>?.05). Conclusions: These findings indicate that sub-maximal walking with no load or carrying 10, 15 or 20?kg in a backpack for up to 60?min does not cause respiratory muscle fatigue despite causing an increase in physiological, metabolic and perceptual parameters.
