A general systems approach to the patient, hospital staff, family, and community: implications for health care services

This article concerns the application of a general systems concept to the health care system. A system consists of a set of interacting components which are interrelated and interdependent, and function as a unit. In order to identify some of the significant influences on the patient who has been hospitalized, this general systems concept has been applied to health care systems at a number of open systems levels in which he or she participates. These are the body-mind system of the patient (an organism); the patient-hospital staff system (an organization); the system relating the patient to his or her family (a group); and the patient-community system. Analyses of the strategic parts of these systems, their mutual dependencies and the processes which link them, together with their functions, have implications for both hospital-based health-care professionals and hospital administrators. These analyses are generalizable across these four levels of systems. Their implications have importance for health care services.     

Divergence of the world city system from national economies

This study shows that the position of cities in the world economy has diverged from national economies. Using data from 2016, we evaluate a network of 12,802 cities formed by the location decisions of 24,355 firms in terms of their point centrality, and show that the inter-city and inter-national systems have measurably decoupled, disrupting the previously-observed pattern in which the most powerful cities in the world city system were located in core countries, "mid-level" cities were in the semi-periphery,and the least powerful cities were in peripheral countries. Our findings support predictions that globalizing cities would diverge from national economies and that globalization would generate a new global geography that transects long-standing cleavages in the world system.     

Immigration Policy,Equilibrium Unemployment,and Underinvestment in Human Capital

We analyse the impact of different immigration policies on human capital investment in a search‐theoretic model. This class of models features unemployment and underinvestment in human capital. The underinvestment in human capital can be solved by combining immigration policy with appropriate education subsidies. Extending the model with respect to different skill groups allows to analyse the observed bimodal skilled immigration of the USA.     

The Role of Firm Size and Performance Pay in Determining Employee Job Satisfaction Brief: Firm Size,Performance Pay,and Job Satisfaction

Abstract. Job satisfaction reflects the on‐the‐job utility of workers and has been found to influence both the behavior of workers and the productivity of firms. Performance pay remains popular and widely used to increase worker productivity and more generally align the objectives of workers and firms. Yet, its impact on job satisfaction is ambiguous. Whereas the increased earnings increase job satisfaction, the increased effort and risk decreases job satisfaction. This paper finds empirical evidence that on net performance pay increases job satisfaction but does so largely among union workers and males in larger firms.     

Evolving Fertility Goals and Behaviors in Current U.S. Childbearing Cohorts

In the post-Recession era, U.S. fertility rates have continued to fall. It is unclear if these declines are driven by shifts in fertility goals or growing difficulty in achieving goals. In this paper, we construct synthetic cohorts of men and women to examine both cross-cohort and within-cohort changes in fertility goals using multiple cycles of the National Survey of Family Growth. Although more recent cohorts exhibit lower achieved fertility at younger ages than earlier cohorts at the same age, intended parity remains around two children, and intentions to remain childless rarely exceed 15 percent. There is weak evidence of a growing fertility gap in the early 30s, suggesting more recent cohorts will need considerable childbearing in the 30s and early 40s to “catch up” to earlier goals, yet low-parity women in their early 40s are decreasingly likely to have unfulfilled fertility desires or intentions to have children. Low-parity men in their early 40s, though, are increasingly likely to intend children. Declines in U.S. fertility thus seem to be largely driven not by changes in early-life fertility goals so much as either a decreasing likelihood of achieving earlier goals or, perhaps, shifts in the preferred timing of fertility that depress period measures.     

The Role of Operational Interdependence and Supervisory Experience on Management Assessments of Resource Planning Systems

Greater interdependence among workers and activities not only increases the need for internal communication, but it also imposes complications and barriers to effective information exchange. Intraorganizational communication capabilities of certain information systems can help overcome these barriers. However, the extent to which certain systems are promoted as communication tools depends largely on management's interpretation of their usefulness, which in turn may be largely dependent on operational context and managerial experience. We use a controlled experimental approach to study how these issues interact to impact managerial assessments of resource planning systems. Results show that managers value the communication capabilities of resource planning systems more so in highly task‐interdependent contexts and that these assessments are still more positive among managers with greater supervisory experience. As a result, these findings pose direct implications regarding the management support of technology use.     

The Dynamics of Inequality

The past forty years have seen a rapid rise in top income inequality in the United States. While there is a large number of existing theories of the Pareto tail of the long‐run income distributions, almost none of these address the fast rise in top inequality observed in the data. We show that standard theories, which build on a random growth mechanism, generate transition dynamics that are too slow relative to those observed in the data. We then suggest two parsimonious deviations from the canonical model that can explain such changes: “scale dependence” that may arise from changes in skill prices, and “type dependence,” that is, the presence of some “high‐growth types.” These deviations are consistent with theories in which the increase in top income inequality is driven by the rise of “superstar” entrepreneurs or managers.
