THE IMPACT OF R&D INVESTMENT ON PRODUCTIVITY–NEW EVIDENCE USING LINKED R&D–LRD DATA

This paper uses confidential Census longitudinal microdata to examine the association between R&D and productivity for the period 1972–1985. These data allow for significant improvements in measurement and model specification, yielding more precise estimates of the returns to R&D. Our results confirm the findings of existing studies: 1) positive returns to R&D investment 2) higher returns to company-financed research 3) a productivity "premium" on basic research These results are robust to adjustments for "influential outliers." Also, our evidence suggests that the return to company-financed R&D is an increasing function of firm size.     

THE INTEGRATIVE PSYCHOTHERAPY ALLIANCE: FAMILY,COUPLE AND INDIVIDUAL THERAPY SCALES*

The therapeutic alliance concept has been confined primarily to the literature on individual psychotherapy. This paper formally introduces the concept into the family and marital therapy domain and presents various clinical hypotheses about the nature of the alliance and its role in familyand marital therapy. A systemic perspective is brought to bear on the concept within individual psychotherapy. A new, integrative definition of the alliance is presented that conceptualizes individual, couple and family therapy as occurring within the same systemic framework. The implications of this integrative-alliance concept for family, couple and individual therapy research are examined. Three new system-ically oriented scales to measure the alliance in individual, couple and family therapy are presented along with some preliminary data on their methodological characteristics.     

TEAM RACIAL COMPOSITION AND SPORTS ATTENDANCE

The premise that the racial composition of professional sports teams is a significant factor in explaining paid attendance variability is tested in this article. A model of the general determinants of sports attendance, including the percentage of black players on each team, is developed and applied to longitudinal samples of National Basketball Association teams from 1969 to 1983. This pooled cross-sectional panel model is analyzed within a generalized least-squares framework. While the empirical results are generally consistent with previous estimates for spectator attendance models, team racial composition has no discernible impact upon the level of attendance. Several interaction hypotheses are considered, but when these more complex propositions are evaluated, player race still has no noticeable effect upon attendance. Some implications of these results for race relations and for the structure of salary determination within professional basketball are discussed.

Linking race and well-being within a biopsychosocial framework: variation in subjective sleep quality in two racially diverse older adult samples

Differential life experiences associated with race may critically affect the balance between physical and psychological well-being. This study investigated an age-related and disease-related symptom, restless sleep, among older African American and white members of two sociodemographically matched cohorts, community-dwelling older adults and older adults with chronic renal failure undergoing maintenance dialysis therapy. Sleep behaviors reflect age-dependent and disease-dependent homeostatic and circadian state regulation but are also socioculturally patterned. As hypothesized, restless sleep was significantly more characteristic of the older adults in the chronic disease cohort. With non-renal health conditions, depressed mood, perceived health, medication use, and sociodemographic variables controlled, however, African Americans were significantly less likely than whites in the chronic disease cohort to report restless sleep. African American and white patients differed in their expression of public and private religiousness, which in turn were associated, respectively, with depressed mood and restless sleep complaint. In addition, we suggest that differences for African American and white patients in the environmental exposure of chronic dialysis therapy, including African Americans' greater social integration within the dialysis treatment setting, contributed to their being less at risk than their white peers for subjective perception of sleep decay, a marker of overall well-being.     

College smoking-cessation using cell phone text messaging

Although rates of smoking among college-aged students continue to rise, few interventions that focus on college smokers' unique motivations and episodic smoking patterns exist. The authors developed and evaluated a prototype program targeting college students that integrates Web and cell phone technologies to deliver a smoking-cessation intervention. To guide the user through the creation and initialization of an individualized quitting program delivered by means of cell phone text messaging, the program uses assessment tools delivered with the program Web site. Forty-six regular smokers were recruited from local colleges and provided access to the program. At 6-week follow-up, 43% had made at least one 24-hour attempt to quit, and 22% were quit--based on a 7-day prevalence criterion. The findings provide support for using wireless text messages to deliver potentially effective smoking-cessation behavioral interventions to college students.     

The Use of Mental Models in Chemical Risk Protection: Developing a Generic Workplace Methodology

We adopted a comparative approach to evaluate and extend a generic methodology to analyze the different sets of beliefs held about chemical hazards in the workplace. Our study mapped existing knowledge structures about the risks associated with the use of perchloroethylene and rosin-based solder flux in differing workplaces. "Influence diagrams" were used to represent beliefs held by chemical experts; "user models" were developed from data elicited from open-ended interviews with the workplace users of the chemicals. The juxtaposition of expert and user understandings of chemical risks enabled us to identify knowledge gaps and misunderstandings and to reinforce appropriate sets of safety beliefs and behavior relevant to chemical risk communications. By designing safety information to be more relevant to the workplace context of users, we believe that employers and employees may gain improved knowledge about chemical hazards in the workplace, such that better chemical risk management, self-protection, and informed decision making develop over time.     

A MODEL FOR TRAINING PRACTICING PROFESSIONALS IN FAMILY THERAPY*

This paper offers a model for high quality training in family therapy. The unique aspects of the Family Consortium's model are that it: (a) is aimed at practicing professionals; (b) emphasizes structural family therapy principles with strategic and experiential elements; (c) is geared secondarily toward training members as effective peer consultants and trainers; and (d) uses an awareness of the isomorphic nature of training, therapy and family transactions. Part I describes the practical organization structure of the Consortium. Part II discusses the current theoretical philosophy and training approach of this evolving group. Examples are given of how the Consortium has dealt with specific training issues.     

Bell Canada: A case study of dynamics of new technologies in a changing environment

This paper provides a case example of a firm experiencing significant change. Bell Canada is Canada's largest public telecommunications carrier. In recent years the company has found itself facing more pervasive new challenges than it had over most of its 111 year history. Elements of change driving the firm have their origins in technological advances, changing market expectations and reform in regulatory conditions. The paper provides examples and reference points for the changing management information needs required to cope with the new environmental realities. In particular, attention is paid to the need for management and regulatory flexibility and responsiveness as keys for dealing with change.This case study suggests the need to adopt new approaches to relevant information needs as a company moves away from the well defined domain of its operations. It explores the more critical information needs that have charged in the Bell Canada context. Although the analysis has reflected a single firm in transition, and there are bound to be differences, we hope that it can provide at least general guidance for other firm facing the dynamics of new technologies and global environment.In business, the survival instinct is intensified by the emerging global competitive environment. In every industry there is evidence of increased attention to the fundamentals of viability under rapidly changing conditions. Companies facing the reality or impending threat of increased competition, often from new sources, may feel that their backs are to the wall. If, in addition, these companies face the difficult transition from a regulated monopoly to a more competitive environment the pressure can be powerful indeed.
