Dentists' incomes, fees, practice costs, and the Economic Stabilization Act: 1952 to 1976. Bureau of Economic and Behavioral Research.

Throughout the 20-year period from 1952 to 1972, dentists' net incomes, adjusted for inflation, increased and provided greater monetary rewards to the practice of dentistry. Evidence discloses a close association between the purchasing power of dentists' net incomes and the general level of economic activity (measured by the GNP inconstant dollars). Dentists are not immune to temporary recessions. The period from 1972 to 1974, with the imposed fee guidelines of Nixon's Economic Stabilization Act, was unusual. With effective fee guidelines during the latter two phases coupled with freely fluctuating input prices, dentists were caught in an income squeeze. During 1972 to 1974, the purchasing power of dentists' net incomes fell at a rate of 10.1% per year as the price index of practice costs outpaced dentists' fees. After the Economic Stabilization Act expired in 1974, trends returned to normal. Dentists' net incomes increased at rates consistent with changes in the GNP and dentists' fees increased slightly faster than the "Price Index of Cost of Conducting a Dental Practice."

[Productive life-span of dairy cows and its economic significance. III. Economic evaluation: results obtained by model calculations (authors transl)].

A reduction of the forced replacement rate is found to be of major economic importance on the farm level. In the model, the income earned from a fifth lactation of a cow showing an average production is approximately Dfl 440 higher than the earned income per annum over the average herd life of 4.3 lactations. A farm with a herd of fifty cows showing average production and an average herd life of 5.3 years will have approximately Dfl 9600 more earned income each year than a similar farm with an average herd life of 3.3 years. The yield resulting from a longer herd life is subject to the law of diminishing returns. For the annual income from a dairy herd, a sixth lactation is of less importance than a fifth lactation, etc. The economic importance of a long herd life appears to be remarkably stable, i.e. hardly affected by: (a) The average productive capacity of the herd as regards milk and/or meat. (Note: Differences in milk-producing capacity within a herd have a marked effect on the economic value of an additional lactation by an individual cow). (b) The presence or absence of a moderate genetic improvement (1 per cent per annum) in milk-yield.

[Productive life-span of dairy cows and its economic significance. II. The replacement of dairy cows: an economic model (author's transl)].

A model, initially based on the work of Zeddies (10), is presented , by which the economic aspects of the replacement problem may be studied. First, the principle underlying the replacement decision is discussed. Then, the data to be included in the model are determined. This mainly concerns the elements associated with age, such as milk production, the value of newborn calves, the slaughter of the cows, the feed cost and the cost of a pregnant heifer just before calving. The age-associated probability of culling is also included in the model. A number of questions regarding the economic importance of the duration of herd life have been studied using this model. In the third paper, the results of this application of the model will be presented.

[Economic management. Why economic regulation of prevention?].

There is much lip service but little practical every day behavior aiming at prevention. Instructors and practitioners or health promotion and health protection experience much less recognition than the healers of diseases. Infrastructure and training for prevention let much to be desired. Only a political action on a higher level can give preventive measures the weight they deserve. Economic mechanisms seem the most appropriate way of regulation.

Longitudinal Relations among Perceived Economic Stress, Teacher-Student Relationships, and Cybervictimization: Exploring Within-Person Links.

Family economic hardship has been identified as a risk factor for adolescents' cybervictimization. Nevertheless, existing studies have primarily focused on objective economic conditions, and little is known about the within-person association between perceived economic stress and adolescents' cybervictimization and the mediating mechanisms underlying this association. To fill these gaps, the random intercept cross-lagged model was employed to examine the dynamic relations among perceived economic stress, teacher-student relationships, and cybervictimization. The data were obtained from a sample of 2407 Chinese adolescents (Mage = 12.75, SD = 0.58, 50.23% girls at baseline) recruited from seven schools and assessed at three time points over one year. At the between-person level, there were no significant associations among perceived economic stress, teacher-student relationships, and cybervictimization. At the within-person level, perceived economic stress positively predicted later cybervictimization over time, and this effect was unidirectional. The bidirectional relations between perceived economic stress and teacher-student relationships remained stable over time. Cybervictimization significantly and negatively predicted subsequent teacher-student relationships across time, indicating a unidirectional predictive effect. Additionally, perceived economic stress indirectly predicted cybervictimization through teacher-student relationships. The findings highlight the importance of distinguishing within-person from between-person processes and shed light on the longitudinal role of teacher-student relationships in the association between perceived economic stress and cybervictimization.

Cost-Effectiveness of Electronic Patient-Reported Outcome Measure Interventions in Cancer: Systematic Review and Parameter Extraction for Economic Modeling.

BACKGROUND: Complex digital interventions that integrate electronic patient-reported outcome measures (ePROM) into clinical practice in cancer have the potential to improve quality of life, increase survival, and reduce health resource use and costs. Such systems can help patients with cancer self-manage chemotherapy symptoms, reduce clinicians' workloads through automated decision support, and resolve problems earlier. However, more research on the cost-effectiveness of ePROM monitoring is needed. OBJECTIVE: This paper comprises two complementary components: (1) a systematic literature review summarizing and evaluating the quantitative and qualitative evidence related to the cost-effectiveness of ePROM monitoring and (2) a health economic model parameter extraction. We also conducted supplementary targeted searches and scoping to provide context to our findings. METHODS: We searched Ovid (including MEDLINE and Embase), Scopus, and the International Health Technology Assessment Database for original English-language papers published on or before March 2025 using search strings that combined terms related to ePROMs, health economics, and cancer/oncology. We included papers reporting health economic-related outcomes for ePROM interventions designed for adult cancer populations and excluded screening tools and conference abstracts. RESULTS: We included 34 publications from 27 unique studies and identified and analyzed 26 ePROM-integrated interventions within these. Most (23/26) of the included interventions explicitly described some form of alert handling and automated decision support based on remote ePROM monitoring. Of the 34 publications, 5 presented full cost-effectiveness analysis results, of which 3 were highly uncertain and lacked clear differences in costs and health outcomes between ePROMs and standard care; conversely, 2 presented strong evidence of cost-effectiveness due to quality-of-life improvements, reduced hospitalizations, and potentially more autonomy in health-related travel (eg, ePROM-monitored patients can drive or walk to the hospital instead of using taxis or ambulances). A further 5 publications reported partial health economic results (eg, cost-consequence and budget impact), of which 1 detected no difference in strategies; in contrast, 4 reported lower health resource use and costs of ePROMs, mainly due to hospitalization reductions. Overall, 12 of the 27 studies included a qualitative component but mostly focused on user experience and design-related themes; only 2 of these addressed economic-specific themes (eg, changes in workflow and resource use due to ePROM implementation and integration), indicating some potential for time saving due to ePROM monitoring. CONCLUSIONS: Some ePROM-integrated interventions demonstrated cost-effectiveness in cancer care, but the evidence base remains limited. Where evidence does exist, cost-effectiveness appears driven by reduced hospitalization and improved quality of life. Qualitative research within the included studies rarely addressed economic questions. We provide a detailed parameter extraction for use in future economic modeling and recommend research priorities, including quantitative mapping of ePROM symptom data onto health resource use patterns, and qualitative work exploring how ePROM implementation affects clinical workloads and patient-perspective costs.

Some economic and technical factors affecting use of phosphate raw materials.

In comparison with phosphate resources most of the other industrial minerals essential to man have much higher unit values. Furthermore, they generally have more narrowly defined geochemical origins, concentration requirements, and end-use markets. Consequently, an economic assessment of their mined production cost in relation to market value is more easily and reliably defined. Thus, the mere knowledge of existing or newly discovered ore bodies provides economic incentives for exploitation plans--even in the most remote geographical location (as is well illustrated by iron, copper, tin, lead, and similar mineral commodities). Unfortunately, this is not the case for phosphate resources. Much of the known vast reserves of more than 1 X 10(11) tons, which are favourably dispersed among the worldwide markets, remains uneconomical to recover, despite the growing need for phosphate in world food production. A complex set of interrelated technical and economic factors decide the economic potential of any particular phosphate reserve. Although technical similarities may exist among deposits, economic analogies are rare. The economic evaluation of the mineability of the ore and the mill preparation of the concentrates must also take into account the geological setting and character of the ore deposit as well as the eventual end-use markets and their locations.

[Economic crime].

Economic crime, often also referred to as white collar crime, is one of the most incidious and predatory of offenses. Unlike street crime, for which there may well be some protection, the average citizen is completely at the mercy of the perpetrators of economic crimes. The concept of white collar crime was first identified by Edwin H. Sutherland. He dealt with the problem as a violation of trust involving either or both misrepresentation and duplicity. He argued for the use of criminal sanctions rather than civil remedies as a means of dealing with white collar offenses. Sutherland's views were attacked by the legal profession, by sociologists and criminologists and by public opinion specialists. They contended that an act treated in civil court is not a crime; that criminals are those persons who are defined as such and white collar criminals are neither so defined nor do they define themselves as criminals and, finally, that economic crime is universal. Can anyone be criminal, then, ask the critics? A number of studies by Clinard, Quinney, Black, Ball, Cressey, Newman and others have translated the interest in white collar crime into empirical terms. The last thirty-five years have also witnessed the elaboration and alteration of the theory itself. Geis' work has been particularly important in this respect. His "street" versus "suite" crime is a useful dichotomy. Most important, however, have been the monograph and papers by Herbert Edelhertz who has conceptualized the issues on various levels - from consumer fraud to the illegal activities of the multinational corporation. This article is concerned with the exposition of the theory and research in the field. Most significant, the paper raises serious doubts whether the problem of economic crime can be researched and studied; it raises even more difficult issues concerning the legal and sociological implications of economic crime and of its prevention, management and control.
