P-Drive: Implementing an Assessment of On-Road Driving in Clinical Settings and Investigating Its Internal and Predictive Validity
Authors: Patomella Ann-Helen , Bundy Anita 
Published: June 2015

Abstract
We investigated (1) the psychometric properties of data gathered with the Performance Analysis of Driving Ability (P-Drive), an on-road assessment; (2) P-Drive’s predictive validity in relation to a summed decision of passing or failing a medical driving evaluation; and (3) the success of implementing P-Drive. Drivers (N = 99) with neurological impairment referred for a driving evaluation were observed on road and scored using P-Drive. Results showed evidence of person response validity and internal validity. P-Drive separated the drivers into four different strata (reliability coefficient = .92). A cutoff raw score of 81 was optimal, with sensitivity of 93% and specificity of 92%. Although only 9 occupational therapists (of 19 initially trained) contributed data for analysis, 17 reported using the assessment. Data gathered with P-Drive yielded evidence of excellent psychometric properties. Moreover, P-Drive was implemented successfully in clinical settings, although initial training to full implementation took longer than 1 yr.
Forced Aerobic Exercise Enhances Motor Recovery After Stroke: A Case Report
Authors: Linder Susan M. , Rosenfeldt Anson B. , Rasanow Matthew , Alberts Jay L. 
Published: June 2015

Abstract
OBJECTIVE. Previously, we demonstrated that forced aerobic exercise (FE) increases the pattern of neural activation in Parkinson’s disease. We sought to evaluate whether FE, when coupled with repetitive task practice, could promote motor recovery poststroke.
METHOD. A 46-yr-old man with ischemic stroke exhibited chronic residual upper-extremity deficits, scoring 35/66 on the Fugl-Meyer Assessment (FMA) at baseline. He completed 24 training sessions comprising 45 min of FE on a motorized stationary bicycle followed by 45 min of upper-extremity repetitive task practice.
RESULTS. From baseline to end of treatment, the FMA score improved by 20 points, perceived level of recovery on the Stroke Impact Scale increased by 20 percentage points, and cardiovascular function measured by peak oxygen uptake improved 30%. These improvements persisted 4 wk after the intervention ceased.
CONCLUSION. FE may be a safe and feasible rehabilitation approach to augment recovery of motor and nonmotor function while improving aerobic fitness in people with chronic stroke.
Hurricane Sandy, Disaster Preparedness, and the Recovery Model
Authors: Pizzi Michael A. 
Published: June 2015

Abstract
OBJECTIVE. Hurricane Sandy was the second largest and costliest hurricane in U.S. history to affect multiple states and communities. This article describes the lived experiences of 24 occupational therapy students who lived through Hurricane Sandy using the Recovery Model to frame the research.
METHOD. Occupational therapy student narratives were collected and analyzed using qualitative methods and framed by the Recovery Model. Directed content and thematic analysis was performed using the 10 components of the Recovery Model.
RESULTS. The 10 components of the Recovery Model were experienced by or had an impact on the occupational therapy students as they coped and recovered in the aftermath of the natural disaster.
CONCLUSION. This study provides insight into the lived experiences and recovery perspectives of occupational therapy students who experienced Hurricane Sandy. Further research is indicated in applying the Recovery Model to people who survive disasters.
Brokenness and Hope David Lynch's Contribution to a Phenomenology of Anxiety in Mulholland Drive
Authors: Bradley Daniel 
Published: June 2015

ABSTRACT
In The Concept of Anxiety, Kierkegaard makes a powerful phenomenological distinction between fear and anxiety; one fears this or that thing, but one is anxious of “nothing.” Kierkegaard understands this terror before the nothing as a revelation of freedom. This is correct but incomplete. Anxiety does, indeed, transcend fear of this or that possibility to encounter possibility itself. But it also transcends guilt about this or that sin, to encounter sinfulness itself, or the general brokenness of the social injustices and cultural illusions into which we find ourselves always already thrown. We see this neglected aspect of anxiety masterfully revealed in David Lynch's, Mulholland Drive. This film opens as a typical mystery plot, but the most important clue in the film is anxiety. The anxiety, which we and ultimately the protagonist, Betty, cannot evade, reveals the inescapability of her responsibility and her guilt in a murder. However, this anxiety also points beyond her personal responsibility for the crime to a deeper understanding of the structural distortions and illusions that permeate Hollywood culture and modern life more generally. In other words, it points us beyond an existential analysis of freedom to a hermeneutics of suspicion. Returning to the plot of the film with this philosophical turn in hand helps us to see past Betty's guilt to the more important theme, the tragedy of her death.
Klein and Cassirer Symbol and Symbolic Form
Authors: Halper Edward 
Published: June 2015

ABSTRACT
In Greek Mathematical Thought and the Origin of Algebra, Jacob Klein contrasts ancient Greek philosophy's direct engagement with things through arithmetic with the ancient science of numeric calculation, logistic. By chronicling the later development of logistic, by means of increasing symbolization, ultimately into algebra, he argues that logistic has come to displace arithmetic and, thereby, to submerge the ontological issues at the center of Greek thought. This article argues, first, that Klein's target is Ernst Cassirer's notion of number as a “symbolic function”—what Cassirer would later call “symbolic form.” In Substance and Function Cassirer argues that number constitutes a conceptual structure progressively extended by thought so as to include the results of different sorts of calculation (e.g., negative numbers, irrational roots, and infinite numbers) within itself and, thereby, to be a closed system. Drawing upon Dedekind, Cassirer claims that no individual number can be understood apart from the entire conceptual structure. This article argues, second, that Cassirer recognizes, as it were, a different set of things, namely, relations, and that it is possible to engage these “things” directly by recognizing the ontological issues they raise.

Platgeslagen platforms
Online platforms verlagen transactiekosten en maken gebruik van positieve externe effecten door vragers en aanbieders samen te brengen. Om investeringen in platforms tegen ‘free riding’ te beschermen, kunnen platforms met de aanbieders die op het platform actief zijn ‘most favoured nation’-clausules bedingen of soortgelijke afspraken maken. Aangezien mededingingsautoriteiten door heel Europa dergelijke clausules te lijf (willen) gaan, is het van belang om de economische kant nog eens te benadrukken.
De bestudering van criminaliteit op macroniveau: een inleiding
Authors: Weerman Frank , van der Laan André , Haen Marshall Ineke , Pauwels Lieven 
Published: June 2015

The study of crime on a macro level: an introduction
In this introductory article we introduce the subject of our thematic issue on ‘macro criminology’, and illustrate it with a short historical overview and examples of ‘typical macro criminological’ research. Successively we address the recent decrease in crime in many Western countries (the ‘crime drop’), the increased tendency to punish more severely in the last decennia (the ‘punitive turn’), and historical developments in homicide (‘history of violence’). After that we address an important theoretical and philosophical problem with regard to macro criminology: the balance between micro and macro factors in explaining macro phenomena. Finally, the contributions of this thematic issue are introduced.
Daling in geregistreerde jeugdcriminaliteit

Decline in registered juvenile crime: some potential macro explanations
In the Netherlands, from 2007 police census data show a sharp decrease in the number of suspects of crime among juveniles aged 12 to 25 years old. How to explain this decrease remains unclear. Constructionist theories suggest that changes in police census data are fully explained by changes in the law enforcement system. Normative theories argue that changes in police data can be explained by demographic, social or economic trends. In this paper, we systematically explored the (inter)national literature for macro factors that could explain changes in juvenile crime. Next, in an empirical case study of the city of Amsterdam, we explored which of these macro factors relate to changes over time in the number of juvenile suspects of crime and the types of crime they were suspected of. Due to multicollinearity of the macro factors multivariate analyses were not possible. Our results indicate that the decrease in police registered juvenile crime in Amsterdam should be explained by multiple factors. Some of these factors concern policy investments (such as focus on school drop-out and targeted law enforcement), other factors relate to socialdemographic developments which appeared coincidentally.
Trends in perceptie van criminaliteit
Authors: Eysink Smeets Marnix , Vollaard Ben 
Published: June 2015

Trends in perception of crime
Some overestimation of crime risk is likely, but that does not mean that risk perceptions are not adjusted in line with changes in actual crime risk. Based on time series data, we show that crime risk perceptions are strongly related to rates of victimization. The conventional wisdom that the drop in crime since the 1990s did not result in an adjustment in risk perceptions can be easily refuted. The much discussed crime drop goes together with a much less discussed fear drop.

AbstractConsiderable research has been dedicated to restoring myocardial cell slippage and limiting ventricular remodeling after myocardial infarction (MI). We examined the ability of a three-dimensional (3D) engineered fibrin patch filled with human umbilical cord blood-derived mesenchymal stem cells (UCBMSCs) to induce recovery of cardiac function after MI. The UCBMSCs were modified to coexpress luciferase and fluorescent protein reporters, mixed with fibrin, and applied as an adhesive, viable construct (fibrin-cell patch) over the infarcted myocardium in mice (MI-UCBMSC group). The patch adhered well to the heart. Noninvasive bioluminescence imaging demonstrated early proliferation and differentiation of UCBMSCs within the construct in the postinfarct mice in the MI-UCBMSC group. The implanted cells also participated in the formation of new, functional microvasculature that connected the fibrin-cell patch to both the subjacent myocardial tissue and the host circulatory system. As revealed by echocardiography, the left ventricular ejection fraction and fractional shortening at sacrifice were improved in MI-UCBMSC mice and were markedly reduced in mice treated with fibrin alone and untreated postinfarction controls. In conclusion, a 3D engineered fibrin patch composed of UCBMSCs attenuated infarct-derived cardiac dysfunction when transplanted locally over a myocardial wound.SignificanceIschemic heart failure (HF) is the end stage of many cardiovascular diseases, including myocardial infarction. The only definitive treatment for HF is cardiac transplant, which is hampered by limited number of heart donors and graft rejection. In recent times, cellular cardiomyoplasty has been expected to repair infarcted myocardium by implantation of different sources of stem or progenitor cells. However, low cell survival and myocardial implantation rates have motivated the emergence of novel approaches with the objective of generating graftable cell-based implants. Here, the potential of 3D engineered fibrin-umbilical cord blood-derived mesenchymal stem cells patches is shown to significantly recover lost general functions in post-infarcted mice.
Getting Used to Being a Patient: The Postoperative Experience of Living Liver Transplant Donors

Published: June 2015

Context— Living donor liver transplant is a viable option for eligible persons in need of a liver transplant, but little is known about the hospitalization experience of patients undergoing hepatectomy for transplant donation. Objective— To explore the hospital experience of patients recovering from donor hepatectomy. Design— A qualitative interpretive descriptive design was used to understand the hospital experience of patients recovering from donor hepatectomy. Semistructured interviews, conducted before discharge, were audiotaped and transcribed verbatim. Coding was performed independently, then jointly by investigators to reach consensus on emerging themes. Setting— Major university hospital in the Northeastern United States. Sample— Adults (>18 years of age) whose primary language was English or Spanish and who could provide written informed consent. Results— The sample consisted of 15 participants who had a mean age of 34.6 years; half were women. Most were white and college educated. The relationship of the donors to recipients varied from immediate family to altruistic donors. “Getting used to being a patient” was the major theme that captured the patients' postoperative experience. Four subthemes explained the experience: regaining consciousness, all those tubes, expecting horrible pain, and feeling special and cared for. These were described in the context of an “amazing and impressive” transplant team. Conclusion— As healthy donors are getting used to being patients, these results provide clinicians with a deeper understanding of the transplant experience from the donor's perspective so that care can be tailored to meet their unique needs.

Published: June 2015

Context— Solid-organ transplant is the treatment of choice for end-stage organ failure and requires a transition from management of a life-threatening condition to a chronic illness. Despite research focusing on quality of life after transplant, there is a gap addressing the role of managing a chronic illness focusing on vulnerability and impact on family. Objective— Identify patient and family patterns of adaptation among kidney and liver transplant recipients in regard to (1) vulnerability, (2) impact of illness on the family, (3) family functioning, and (4) quality of life (parent and child report). Design— Cross-sectional study enrolling children 5 to 18 years old and their parent at a single time point after kidney or liver transplant. Validated self-report tools were completed. Results— In all, 47 participants (24 kidney and 23 liver) were recruited. Mean age at transplant was 4.0 (kidney) and 2.1 (liver) years. Mean age at report was 12.1 (kidney) and 7.1 (liver) years. Child vulnerability correlated negatively with (1) family impact in the kidney ( P < .05) and liver ( P < .05) transplant groups, (2) PedsQL subscales including Parent Emotional ( P < .05), Parent Social ( P < .01), Parent Psychosocial ( P < .01), Parent Physical ( P < .05), Parent School ( P < .05), and Child Social ( P < .01) in the kidney transplant group, (3) PedsQL Parent Emotional subscale ( P < .01) in the liver transplant group, and (4) Functional status ( P < .01) in the liver transplant group. Conclusions— Child vulnerability provides insight into quality of life and the impact of illness on the family and family functioning.
Development and Initial Evaluation of the Psychometric Properties of Self-Efficacy and Adherence Scales for Patients with a Left Ventricular Assist Device

Published: June 2015

Context— No tools exist to measure patients' self-efficacy for and adherence to the complex home-care regimen after having a left ventricular device (LVAD) implanted. Objective— To develop 2 new instruments, the LVAD Patient Self-Efficacy Scale (LPSES) and the LVAD Patient Home Management Adherence Scale (LPHMAS), and evaluate their psychometric properties. Methods— This multistage instrumentation study recruited 102 patients (77.5% men and 22.5% women) aged 20 to 82 years, predominantly from the Midwest (34.3%) and the Northeast (26.5%) regions of the United States. Main indications for LVAD were bridge-to-transplant (69.6%) and destination therapy (21.6%), with mean implant duration of 19.9 (SD, 15.5) months. Study participants completed the following instruments: LPSES, LPHMAS, General Self-Efficacy Scale (GSES), Medical Outcomes Study General Adherence (MOSGA), and Self-Care Heart Failure Index (SCHFI) confidence and maintenance subscales. Item analyses, psychometric properties including factorial and convergent validities, and internal consistency reliability were tested. Results— Factor analyses showed that the variances for the 20-item LPSES and 9-item LPHMAS were 60.2% and 53.6%, respectively. Convergent validity of the newly developed instruments was supported by the following correlations: LPSES and GSES ( r = 0.34); LPSES and SCHFI-confidence ( r = 0.60); LPHMAS and MOSGA ( r = 0.33); LPHMAS and SCHFI-maintenance ( r = 0.40). Internal consistency reliability coefficients were 0.94 (LPSES) and 0.84 (LPHMAS). Based on these data, the LPSES and LPHMAS are valid and reliable measures of self-efficacy and adherence specific for LVAD patients. Confirmatory testing is needed to further support the validity of these instruments for use in research and clinical practice.
Transition to Adult Care in Pediatric Solid-Organ Transplant: Development of a Practice Guideline
Authors: Gold Anna , Martin Kathy , Breckbill Katie , Avitzur Yaron , Kaufman Miriam 
Published: June 2015

Background— Transition to adult-centered care is becoming an increasingly important area of practice in pediatric organ transplant. Standardized, best-practice guidelines are needed to assist transplant practitioners in providing optimal transitional care for this population of patients. Objective— To describe the development and implementation of a practice guideline for the transitional care of pediatric transplant recipients. Methods— A quality improvement project was undertaken in a pediatric multiorgan transplant program setting. Strategies employed included (1) creation of an interdisciplinary working group, (2) survey of transition-related practices and learning needs of transplant practitioners, (3) review of the literature and existing transition-related materials, and (4) creation of transition guidelines. Results— An interdisciplinary survey of transplant practitioners at our institution identified practice strengths related to transitional care and learning needs. Review of relevant literature and other materials revealed limited but emerging research related to the transition of pediatric transplant recipients from pediatric to adult care. Existing transition tools were examined and applicable items identified. A practice guideline for use with pediatric transplant recipients transitioning to adult care was developed. Strategies to educate staff about the guideline and promote ongoing guideline use were implemented. Conclusion— Preparing pediatric transplant recipients and their families for transition to adult-centered care is an emerging challenge for transplant teams. These guidelines provide practitioners with a developmentally sensitive overview of important transition-related domains and strategies directed toward patients and their caregivers, who may experience the process of transition differently. Dissemination of the pediatric transplant transition guideline will make transition information more widely available to transplant practitioners.

Published: June 2015

Context— The increasing shortage of deceased donor kidneys suitable for African Americans highlights the critical need to increase living donations among African Americans. Little research has addressed African American transplant recipients' perspectives on challenges and barriers related to the living donation process. Objective— To understand the perspectives of African American recipients of deceased and living donor kidney transplants on challenges, barriers, and educational needs related to pursuing such transplants. Participants and Design— A mixed-method design involved 27 African American kidney recipients (13 male) in 4 focus groups (2 per recipient type: 16 African American deceased donor and 11 living donor recipients) and questionnaires. Focus group transcripts were evaluated with NVivo 10.0 (QSR, International) by using inductive and deductive qualitative methods along with crystallization to develop themes of underlying barriers to the living donor kidney transplant process and were compared with the questionnaires. Results— Four main themes were identified from groups: concerns, knowledge and learning, expectations of support, and communication. Many concerns for the donor were identified (eg, process too difficult, financial burden, effect on relationships). A general lack of knowledge about the donor process and lack of behavioral skills on how to approach others was noted. The latter was especially evident among deceased donor recipients. Findings from the questionnaires on myths and perceptions supported the lack of knowledge in a variety of domains, including donors' surgical outcomes risks, costs of surgery, and impact on future health. Participants thought that an educational program led by an African American recipient of a living donor kidney transplant, including practice in approaching others, would increase the likelihood of transplant-eligible patients pursuing living donor kidney transplant.
Nuclear Reactors
Authors: Murray Raymond L. 
Published: June 2015

AbstractNuclear reactors may be classified by purpose or use, key components, method of heat extraction, power level or neutron flux, or arrangement of component materials. Commercial reactors are also classified by the companies involved in design and building of the facility. Reactors used for power generation, either heat or electrical, propulsion, whether naval vessels or spacecraft, radioisotope production, materials testing, basic research, and training are discussed. The development of nuclear reactors is presented, including information gleaned from the two principal nuclear accidents of the 1980s.The pressurized lightwater reactor is the most common power generation reactor in the United States, but the boiling water reactor is also used. In Canada, heavy‐water reactors are usually employed. These and other reactors, such as the molten salt and the fast breeder reactor, are described.
