Influential observations in cointegrated VAR models: Danish money demand 1973–2003

Summary This paper suggests a set of simple diagnostic tools for assessing the influence of a patch of κ observations in a cointegrated vector autoregressive model. The diagnostics are based on the leave‐κ‐out principle ( Bruce and Martin, 1989 Journal of the Royal Statistical Society, Series B, 51, 363–424) and the influence is measured by the likelihood displacement ( Cook and Weisberg, 1982 Residuals and Influence in Regression. London: Chapman and Hall). An application to Danish money demand 1973–2003 suggests that the observations for real money in 1999 are affected by institutional factors related to the definition of broad money, and that the dynamic adjustment following the international oil‐price shock in 1973 is very influential for the long‐run parameters.

Variation in Dentist Service Rates in a Homogeneous Patient Population

Previous studies in medicine and dentistry document wide variations in service rates across small areas, large regions, and providers. The practice patterns of providers and underlying differences in patient need are thought to be important sources of this variation. To control for variation in patient needs, we calculated service rates of 200 general dentists in Washington state based on a homogeneous, well-educated, upper-middle-class population of patients. Wide variations were found in the rate for many dental services. Dentists' practice beliefs and characteristics of the practice were sources of variation in the rates. The evidence is insufficient to determine whether undertreatment of overtreatment occurred among dentists with the lowest and highest expenditures per patient, respectively. However, the perceived oral health status of adult patients was lower in practices with the lowest total expenditures per patient than in practices with the highest total expenditures per patient, suggesting the undertreatment of adult patients in the lowest-expenditure practices may have occurred.

Periodic Tallies by Regulatory Boards: A Vital Tool for Tracking Supply in the Psychology Workforce

Regulatory boards in psychology and other mental health professions are in key positions to address workforce supply issues. Board data provide real time estimates of the growth within the health professions they regulate. The authors recommend that periodic tallies of the psychology workforce be undertaken through surveys of psychology boards. This will require that boards adopt efficient and standard methods for tracking licensees. Better data from boards would provide longitudinal and cross-jurisdictional comparisons that may enhance efforts to balance supply and demand in the professional workforce and the distribution of psychologists.     

Analysis of Incidence of Atrial Fibrillation after Implantation of VVI Pacemaker-Long-term Observation of 154 Patients

In case of advanced bradycardiac arrhythmiasuch as n o atrioventricular block (AVB) or sick sinus syndrome (SSS), implantation of pacemaker isusually suggested in order to prevent or to managecardiac arrest or cerebral dysfunction. Given the costand improvement of clinical symptoms, pure ventric,ular mode of pacemaker (ventricular demand pacing,or VVI) hAs been commonly used. In' 1992, ElenaSgarbossa reported that ventricular demand pacingremains the most frequently selected modality in th…     

慢性肺心病患者组织氧合的探讨——氧供——氧需的关系

作者运用无创性同时间监测心肺功能的技术,测定了113名健康人、42名无组织缺氧症和45名伴组织缺氧症的肺心病人的外呼吸、心血管和内呼吸功能。结果显示:慢性肺心病病人,只要氧供一氧需保持平衡,就能保证组织氧合;在评价组织氧合时,不能仅仅依靠一些临床常用的在“可接受”范围的指标,如 PaO_2和 (?)_T 等,而应结合 S(?)O_2、COD 和 COU 等进行综合全面评价。     

Needs of Persons with Severe Intellectual Disabilities: a Q‐Methodological Study of Clients with Severe Behavioural Disorders and Severe Intellectual Disabilities

Background A demand‐oriented approach is becoming increasingly important in care provision. The purpose of this study was to identify the primary needs of clients with Severe Behavioural Disorders and Severe Intellectual Disabilities. Materials and Methods We used the theory of Social Production Function and Maslow’s hierarchy of needs to operationalize different types of needs of clients with Severe Behavioural Disorders and Severe Intellectual Disabilities. A Q‐methodological study enabled us to distinguish the needs of 23 clients. Results Two needs prioritizations were found. Physical well‐being ultimately weighs most heavily for all clients, but in one of the two groups affection and behavioural confirmation (i.e. social needs) were also found to be important. There were no significant differences in needs between clients whose main behavioural difficulty was aggression and clients whose main behavioural difficulty was self‐harm. Conclusions A demand‐oriented policy for clients with Severe Behavioural Disorders and Severe Intellectual Disabilities should be targeted at groups with different needs prioritizations, rather than groups with different behavioural problems. That does not mean that the same needs of different clients can be met in exactly the same way. It takes creativity and a person‐centred approach to find ways to enable clients to realize their social and physical needs.
