This Element explores how Congress has designed laws reliant on an assumption of presidential self-restraint, an expectation that presidents would respect statutory goals by declining to use their formal powers in ways that were legally permissible but contrary to stated congressional intent. Examining several laws addressing political appointments since the 1970s – statutes involving the FBI director, Office of Personnel Management director, chairman of the Joint Chiefs of Staff, director of national intelligence, Federal Emergency Management Agency administrator, inspectors general, Senior Executive Service, vacancies, Social Security Administration commissioner, and Consumer Financial Protection Bureau director – the authors demonstrate lawmakers' reliance on presidential self-restraint in statutory design and identify a variety of institutional tools used to signal those expectations. Furthermore, the authors identify a developmental dilemma: the combined rise of polarization, presidentialism, and constitutional formalism threatens to leave Congress more dependent on presidential self-restraint, even as that norm's reliability is increasingly questionable.
The New Jersey Kids Study (NJKS) is a transdisciplinary statewide initiative to understand influences on child health, development, and disease. We conducted a mixed-methods study of project planning teams to investigate team effectiveness and relationships between team dynamics and quality of deliverables.
Methods:
Ten theme-based working groups (WGs) (e.g., Neurodevelopment, Nutrition) informed protocol development and submitted final reports. WG members (n = 79, 75%) completed questionnaires including de-identified demographic and professional information and a modified TeamSTEPPS Team Assessment Questionnaire (TAQ). Reviewers independently evaluated final reports using a standardized tool. We analyzed questionnaire results and final report assessments using linear regression and performed constant comparative qualitative analysis to identify central themes.
Results:
WG-level factors associated with greater team effectiveness included proportion of full professors (β = 31.24, 95% CI 27.65–34.82), team size (β = 0.81, 95% CI 0.70–0.92), and percent dedicated research effort (β = 0.11, 95% CI 0.09–0.13); age distribution (β = −2.67, 95% CI –3.00 to –2.38) and diversity of school affiliations (β = –33.32, 95% CI –36.84 to –29.80) were inversely associated with team effectiveness. No factors were associated with final report assessments. Perceptions of overall initiative leadership were associated with expressed enthusiasm for future NJKS participation. Qualitative analyses of final reports yielded four themes related to team science practices: organization and process, collaboration, task delegation, and decision-making patterns.
Conclusions:
We identified several correlates of team effectiveness in a team science initiative's early planning phase. Extra effort may be needed to bridge differences in team members' backgrounds to enhance the effectiveness of diverse teams. This work also highlights leadership as an important component in future investigator engagement.
Assess effects of antidepressant compliance on healthcare and workplace costs.
Methods:
Using workplace survey data for 2 large employers’ healthcare claims (2004-2006), patient selection criteria considered depression diagnosis and antidepressant claims history. Employed respondents working in the past month were categorized by Medication Possession Ratio into compliance groups by quartiles; bottom/top quartiles were defined as compliant/non-compliant. Direct (medical/drug) costs were measured as insurer payments to providers; indirect (absenteeism/presenteeism) costs were based on one-month recall of workplace performance (hours worked/missed, self-rated performance), estimated as (hours missed x self-reported hourly income). Annualized, inflation-adjusted (2006) costs were compared between compliant/non-compliant groups using multivariate models controlling for baseline characteristics. Analyses were conducted for all patients and a subsample of diagnosed depression patients.
Results:
Among all patients (n=1,224), medical costs were numerically lower for compliant vs. non-compliant patients ($4,857 vs. $5,926, p=0.221); drug costs were significantly higher for compliant patients ($2,329 vs. $1,570, p=0.001). Indirect costs were not statistically different between compliant/non-compliant patients ($22,278 vs. $20,714, p=0.237). Among the depression subgroup (N=488), medical costs were numerically lower for compliant vs. non-compliant patients ($5,005 vs. $7,630, p=0.152) while drug costs were numerically higher for compliant patients ($2,550 vs. $1,829, p=0.153). Absenteeism costs were 30% lower for compliant patients ($7,725 vs. $11,040, p=0.038); presenteeism costs were not significantly different ($19,079 vs. $17,457, p=0.441).
Conclusions:
Absenteeism costs decrease significantly with compliance among depressed patients as do medical costs (not significantly). Further research is warranted regarding reason for poor antidepressant compliance and influence of compliance on costs.
An increased incidence of CHD has been noted in twin gestations and in infants conceived using assisted reproductive technologies. However, CHD in these populations remains understudied and the mechanisms underlying these phenomena remain unclear. We present the case of twins conceived via in vitro fertilisation both with Tetralogy of Fallot and additional cardiac and extracardiac malformations.
An improved understanding of diagnostic and treatment practices for patients with rare primary mitochondrial disorders can support benchmarking against guidelines and establish priorities for evaluative research. We aimed to describe physician care for patients with mitochondrial diseases in Canada, including variation in care.
Methods:
We conducted a cross-sectional survey of Canadian physicians involved in the diagnosis and/or ongoing care of patients with mitochondrial diseases. We used snowball sampling to identify potentially eligible participants, who were contacted by mail up to five times and invited to complete a questionnaire by mail or internet. The questionnaire addressed: personal experience in providing care for mitochondrial disorders; diagnostic and treatment practices; challenges in accessing tests or treatments; and views regarding research priorities.
Results:
We received 58 survey responses (52% response rate). Most respondents (83%) reported spending 20% or less of their clinical practice time caring for patients with mitochondrial disorders. We identified important variation in diagnostic care, although assessments frequently reported as diagnostically helpful (e.g., brain magnetic resonance imaging, MRI/MR spectroscopy) were also recommended in published guidelines. Approximately half (49%) of participants would recommend “mitochondrial cocktails” for all or most patients, but we identified variation in responses regarding specific vitamins and cofactors. A majority of physicians recommended studies on the development of effective therapies as the top research priority.
Conclusions:
While Canadian physicians’ views about diagnostic care and disease management are aligned with published recommendations, important variations in care reflect persistent areas of uncertainty and a need for empirical evidence to support and update standard protocols.
Influenza A (H1N1) pdm09 became the predominant circulating strain in the United States during the 2013–2014 influenza season. Little is known about the epidemiology of severe influenza during this season.
METHODS
A retrospective cohort study of severely ill patients with influenza infection in intensive care units in 33 US hospitals from September 1, 2013, through April 1, 2014, was conducted to determine risk factors for mortality present on intensive care unit admission and to describe patient characteristics, spectrum of disease, management, and outcomes.
RESULTS
A total of 444 adults and 63 children were admitted to an intensive care unit in a study hospital; 93 adults (20.9%) and 4 children (6.3%) died. By logistic regression analysis, the following factors were significantly associated with mortality among adult patients: older age (>65 years, odds ratio, 3.1 [95% CI, 1.4–6.9], P=.006 and 50–64 years, 2.5 [1.3–4.9], P=.007; reference age 18–49 years), male sex (1.9 [1.1–3.3], P=.031), history of malignant tumor with chemotherapy administered within the prior 6 months (12.1 [3.9–37.0], P<.001), and a higher Sequential Organ Failure Assessment score (for each increase by 1 in score, 1.3 [1.2–1.4], P<.001).
CONCLUSION
Risk factors for death among US patients with severe influenza during the 2013–2014 season, when influenza A (H1N1) pdm09 was the predominant circulating strain type, shifted in the first postpandemic season in which it predominated toward those of a more typical epidemic influenza season.

Research of military personnel who deployed to the conflicts in Iraq or Afghanistan has suggested that there are differences in mental health outcomes between UK and US military personnel.
Aims
To compare the prevalence of post-traumatic stress disorder (PTSD), hazardous alcohol consumption, aggressive behaviour and multiple physical symptoms in US and UK military personnel deployed to Iraq.
Method
Data were from one US (n = 1560) and one UK(n = 313) study of post-deployment military health of army personnel who had deployed to Iraq during 2007–2008. Analyses were stratified by high- and low-combat exposure.
Results
Significant differences in combat exposure and sociodemographics were observed between US and UK personnel; controlling for these variables accounted for the difference in prevalence of PTSD, but not in the total symptom level scores. Levels of hazardous alcohol consumption (low-combat exposure: odds ratio (OR) = 0.13, 95% CI 0.07–0.21; high-combat exposure: OR = 0.23, 95% CI 0.14–0.39) and aggression (low-combat exposure: OR = 0.36, 95% CI 0.19–0.68) were significantly lower in US compared with UK personnel. There was no difference in multiple physical symptoms.
Conclusions
Differences in self-reported combat exposures explain most of the differences in reported prevalence of PTSD. Adjusting for self-reported combat exposures and sociodemographics did not explain differences in hazardous alcohol consumption or aggression.
Experts have proposed removing obsessive–compulsive disorder (OCD) from the anxiety disorders section and grouping it with putatively related conditions in DSM-5. The current study uses co-morbidity and familiality data to inform these issues.
Method
Case family data from the OCD Collaborative Genetics Study (382 OCD-affected probands and 974 of their first-degree relatives) were compared with control family data from the Johns Hopkins OCD Family Study (73 non-OCD-affected probands and 233 of their first-degree relatives).
Results
Anxiety disorders (especially agoraphobia and generalized anxiety disorder), cluster C personality disorders (especially obsessive–compulsive and avoidant), tic disorders, somatoform disorders (hypochondriasis and body dysmorphic disorder), grooming disorders (especially trichotillomania and pathological skin picking) and mood disorders (especially unipolar depressive disorders) were more common in case than control probands; however, the prevalences of eating disorders (anorexia and bulimia nervosa), other impulse-control disorders (pathological gambling, pyromania, kleptomania) and substance dependence (alcohol or drug) did not differ between the groups. The same general pattern was evident in relatives of case versus control probands. Results in relatives did not differ markedly when adjusted for demographic variables and proband diagnosis of the same disorder, though the strength of associations was lower when adjusted for OCD in relatives. Nevertheless, several anxiety, depressive and putative OCD-related conditions remained significantly more common in case than control relatives when adjusting for all of these variables simultaneously.
Conclusions
On the basis of co-morbidity and familiality, OCD appears related both to anxiety disorders and to some conditions currently classified in other sections of DSM-IV.
I really bust my butt now that I’m District Manager. I’m doing the same stuff that I did as Assistant District Manager – but that title, you know, I gotta work harder now that people look up to me.
District manager of a retail chain
If she were another manager around here, I would have asked her about the hours she wanted. But Trish is only a waitress, so I just scheduled her however I wanted. There’s nothing wrong with that.
Restaurant manager
I explained the problem thoroughly and respectfully to my General Manager but not the technicians. There’s no reason to involve any of the techs in making decisions. It’s okay just to tell them what to do.
Service manager at auto dealership
The above comments, culled from the senior author’s notes from workplace interviews over the years, suggest that managers are implicitly aware of a connection between justice and status. The district manager suggested that he was attuned to distributive justice when expressing the need to be deserving of his prestigious title. The restaurant manager did not think she was violating procedural justice by failing to give voice in the scheduling process to a lower status person, although she would have given voice to a higher status person. Finally, the service manager was sensitive to satisfying interactional justice by explaining outcomes to his superiors but not to his subordinates.
Not surprisingly, scholars are also familiar with connections between justice (or fairness) perceptions and status. This is particularly evident among sociologists (e.g., McClendon, 1976), who have studied how positions in occupational status hierarchies dictate the shares of rewards to which individuals feel fairly entitled, and psychologists (e.g., Van Prooijen, Van den Bos, and Wilke, 2002), who have examined how people’s thoughts about status led them to be concerned with following fair procedures. Despite such disciplinary links – and in keeping with the general observation that “status occupies a rather minor place in the … organizational behavior literature” (Pearce, Ramirez, and Branyiczki, 2001, p. 155) – connections between justice and status noted in the literature are not fully developed. However, scattered studies suggest that justice and status are interrelated in complex ways. Based on the belief that there is much to be learned about both justice and status by developing a rapprochement between them, we review their interrelationship in the present chapter. To this end, we juxtapose the various theoretical perspectives that shed light on the psychological processes underlying these connections and we also examine several of the most promising research directions stemming from them.
A 2–year study (1990 and 1991) was conducted at the ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) Sahelian Centre, near Niamey, Niger, to select groundnut cultivars tolerant to drought and to examine selection techniques. Thirty-six cultivars known to vary in yield potential were grown under rainfed and irrigated conditions. Crop growth rate (C) and partitioning co-efficient (p) were estimated from phenological and final harvest data. The correlation between years was greater for partitioning than for pod yield (implying a higher heritability for p than for yield). Tolerance as determined by a drought susceptibility index for pod yield (SY), crop growth rate (Sc) and partitioning (Sp) to reproductive sinks showed thirteen cultivars as drought tolerant for either C or p or for both. The Sahelian cultivars 796, 55–437 and TS 32–1 were the most consistent for drought tolerance. Partitioning was the most important yield component affecting yield variation among cultivars.
Obsessive–compulsive disorder (OCD) is probably an etiologically heterogeneous condition. Many patients manifest other psychiatric syndromes. This study investigated the relationship between OCD and co-morbid conditions to identify subtypes.
Method
Seven hundred and six individuals with OCD were assessed in the OCD Collaborative Genetics Study (OCGS). Multi-level latent class analysis was conducted based on the presence of eight co-morbid psychiatric conditions [generalized anxiety disorder (GAD), major depression, panic disorder (PD), separation anxiety disorder (SAD), tics, mania, somatization disorders (Som) and grooming disorders (GrD)]. The relationship of the derived classes to specific clinical characteristics was investigated.
Results
Two and three classes of OCD syndromes emerge from the analyses. The two-class solution describes lesser and greater co-morbidity classes and the more descriptive three-class solution is characterized by: (1) an OCD simplex class, in which major depressive disorder (MDD) is the most frequent additional disorder; (2) an OCD co-morbid tic-related class, in which tics are prominent and affective syndromes are considerably rarer; and (3) an OCD co-morbid affective-related class in which PD and affective syndromes are highly represented. The OCD co-morbid tic-related class is predominantly male and characterized by high conscientiousness. The OCD co-morbid affective-related class is predominantly female, has a young age at onset, obsessive–compulsive personality disorder (OCPD) features, high scores on the ‘taboo’ factor of OCD symptoms, and low conscientiousness.
Conclusions
OCD can be classified into three classes based on co-morbidity. Membership within a class is differentially associated with other clinical characteristics. These classes, if replicated, should have important implications for research and clinical endeavors.
A general method is presented to facilitate the solution of a class of polydisperse spray problems in which a cloud of droplets can be described using a sectional or group model. The procedure involves replacing the original coupled droplet sectional variables conservation equations by a set of uncoupled sectional equations for auxiliary variables. The form of these latter equations is identical to that of the single spray equation for a quasi-monodisperse spray, solutions of which are more readily attainable even for multidimensional spray problems. Thus, these ready-made solutions can be exploited directly for the auxiliary variables, from which solutions can then be constructed in a straightforward manner for the desired original sectional variables. Three illustrative examples for spray diffusion flames with different features of complexity highlight the potential applicability of the proposed method, and indicate the sensitivity of flame characteristics to initial spray conditions and in-spray related phenomena.
Objectives: The diffusion of cost-utility analyses (CUAs) through the medical literature was examined, documenting visible patterns and determining how they correspond with expectations about the diffusion of process innovations.
Methods: This study used 539 CUAs from a registry. It includes data elements comprising year of publication, the research center in which the study was performed, the clinical area covered by the CUA, and the specific journal. Finally, each paper was assigned to a journal type that could be one of the three categories: health services research, general medicine, or clinical specialty.
Results: When the average number of publications is plotted against time, the plot reveals an S-shaped curve. It appears that, whereas CUAs initially were published more frequently in general medical or health services research journals, there was a clear increase in the diffusion of CUA into subspecialty journals over time. The concentration ratio for research centers as measured by the Herfindhal–Hirschman Index decreased over time.
Conclusions: The spread of CUA through the medical literature follows patterns identified for the diffusion of other new technologies and processes. Future research should focus on what impact this spread has had on the practice of medicine and formulation of health policy.
To explore whether differences in vitamin K nutrition might, at least in part, underlie differences in fracture incidence between Asian and European populations, the vitamin K status of older individuals in Shenyang, China (eighty-six men, ninety-two women) and in Cambridge, UK (sixty-seven men, sixty-seven women) was compared. Dietary information was collected by food questionnaire in Shenyang and food diary in Cambridge and used to estimate the intake and sources of phylloquinone. Fasting blood was analysed for phylloquinone, triacylglycerol, total osteocalcin (tOC) and undercarboxylated osteocalcin (expressed as percentage of tOC; %ucOC). The mean intakes of green leafy vegetables were 127 (SD 90) g/d in Shenyang and 39 (SD 48) g/d in Cambridge. The estimated phylloquinone intakes (geometric means) were 247 (95% CI 226, 270) μg/d in Shenyang and 103 (95% CI 94, 112) μg/d in Cambridge. Plasma phylloquinone concentrations (geometric means) were significantly higher in the Shenyang subjects (2·17 (95% CI 1·95, 2·42) nmol/l) than in the Cambridge subjects (0·69 (95% CI 0·63, 0·76) nmol/l; P<0·001). Plasma phylloquinone concentration was positively related to phylloquinone intake in both the Shenyang (coefficient 0·17 (SE 0·08); P=0·03) and Cambridge subjects (coefficient 0·29 (SE 0·10); P=0·005). tOC concentration and %ucOC (after adjusting for tOC) were significantly lower in the Shenyang than in the Cambridge subjects (tOC 25·2 (SE 4·2) % and %ucOC 68·5 (SE 10·0) % lower respectively; P<0·001). After adjusting for tOC and triacylglycerol, %ucOC was negatively related to plasma phylloquinone concentration in both the Shenyang (coefficient −0·41 (SE 0·11); P=0·0003) and Cambridge subjects (coefficient −0·17 (SE 0·07); P=0·02). The present study demonstrates that older individuals in northern China have a better vitamin K status compared with their British counterparts in Cambridge, UK.
