    During shoulder surgery, patients typically are placed in the beach chair position. In rare cases, this positioning has resulted in devastating outcomes of postoperative cerebral ischemia (Cullen and Kirby in APSF Newsl 22(2):25-27, 2007; Munis in APSF Newsl 22(4):82-83, 2008). This study presents a method to noninvasively and continuously hemodynamically monitor patients during beach chair positioning by using the photoplethysmograph signal recorded from a commercial pulse oximeter. Twenty-nine adults undergoing shoulder surgery were monitored before and after beach chair positioning with electrocardiogram, intermittent blood pressure, end tidal carbon dioxide, and photoplethysmograph via Nellcor finger pulse oximeter. Fast Fourier transform (FFT) was used to perform frequency-domain analysis on the photoplethysmograph (PPG) signal for data segments taken 80-120 s before and after beach chair positioning. The amplitude density of respiration-associated PPG oscillations was quantified measuring the height of the FFT peak at respiratory frequency. Results were reported as (median, interquartile range) and statistical analysis was performed using Wilcoxon sign rank test. Data were also collected when vasoactive drugs phenylephrine and ephedrine were used to maintain acceptable mean arterial pressure during a case. With beach chair positioning, all subjects who did not receive vasoactive drugs showed an increase in the FFT amplitude density of respiration-associated PPG oscillations (p chair position than blood pressure or heart rate. With vasoactive drugs, pulse-associated PPG oscillations decreased only with phenylephrine while respiration-associated oscillations did not change. Frequency domain analysis of the PPG signal may be a better tool than traditional noninvasive hemodynamic parameters at monitoring patients during beach chair position surgery.

    To evaluate changes in cerebral tissue oxygen index (TOI) values under the beach chair position before and during general anesthesia in surgical patients with or without cardiovascular risk factors. Prospective study. Operating room in the university hospital. Ninety-one patients undergoing surgery, including healthy patients (n = 28), patients with 1 cardiovascular risk factor (n = 33), and those with more than 1 risk factor (n = 30). Cerebral TOI the day before and during general anesthesia was evaluated using a near-infrared spectroscopy NIRO-200 (Hamamatsu Photonics, Hamamatsu, Japan) for each patient. The initial TOI measurement in the supine position after a 10-minute rest or 10 minute after the endotracheal intubation was followed by measurements in 30° and subsequent 60° upright position for 5 minutes. Phenylephrine 0.1 mg and/or ephedrine 4 mg was administered intravenously to maintain mean blood pressure above 60 mm Hg accordingly. The beach chair position decreased mean arterial blood pressure and heart rate under general anesthesia, although patients with more than 1 cardiovascular risk factor needed significantly more phenylephrine doses to maintain mean blood pressure above 60 mm Hg. Values of TOI were within the normal range of about 70% before and during anesthesia in all groups. The beach chair position under general anesthesia did not alter cerebral oxygenation in patients with or without cardiovascular risk factors showing normal preoperative cerebral TOI values when the mean blood pressure was maintained above 60 mm Hg. The careful management using the cerebral oxygenation monitoring appears to maintain cerebral perfusion in the beach chair position during general anesthesia. Copyright © 2015 Elsevier Inc.

    Devastating neurologic ischemic episodes, such as stroke and deafness, have occurred in patients undergoing shoulder surgery in the beach chair position. We hypothesized that awake patients would be able to avoid significant cerebral deoxygenation events (CDEs) compared with anesthetized patients when procedures were performed in the beach chair position. Sixty patients underwent elective shoulder surgery in the beach chair position. Thirty patients underwent an interscalene block and monitored sedation (awake group); 30 patients underwent general anesthesia (asleep group). Cerebral oxygenation saturation (Scto2) was measured during the procedure. Scto2 values below critical thresholds were defined as CDEs and treated. Baseline mean arterial pressure and Scto2 values were lower in the asleep group during the operation (P chair position treated with regional anesthesia and sedation had almost no cerebral desaturation events, unlike patients who had general anesthesia. Avoidance of general anesthesia in the beach chair position may reduce the risk of ischemic neurologic injury. Copyright © 2013 Journal of Shoulder and Elbow Surgery Board of Trustees.

    In our hospital, we have many cases of ambulatory general anesthesia in the dental treatment of disabled patients. However, if the disability patients have strong refusal to enter the general anesthesia room due to strong phobia, we can not apply the general anesthesia induction. We experienced a dental treatment under ambulatory general anesthesia of a disabled patient who could not sit on any dental chair except for his favorite one. The patient was a 16-year-old boy.

    1997-01-01

    Findings published in the NASA Anthropometric Source Book by Johnson Space Center helped BodyBilt, Inc. to fashion controlled comfort chairs that lessen the harmful effects of gravity on seated workers. Crew members living aboard NASA's Skylab noted that in space the human posture differs from the normal posture caused by the tug of one gravity. There has been an alarming increase in back pain and muscle fatigue in workers, along with a dramatic escalation in repetitive stress injuries. BodyBilt's ergonomically-correct line of office chairs are targeted for the average worker that sits for prolonged periods, be it in the classroom or boardroom. Their roster of national clients lists such organizations as IBM, Microsoft, Texas Instruments, Hewlett-Packard, Eastman-Kodak, Boeing, Motorola, and Walt Disney Studios.

    This was to investigate the ability of Nigerian parents to predict their child's dental anxiety level and the relationship between the child's dental anxiety, general anxiety and behaviour in the dental chair. A group of 53 mothers and 35 fathers and their respective children completed schedules that measured general and dental anxiety. The child's behaviour on the dental chair was also assessed. The child's self report of dental anxiety and general anxiety was compared with that of the parents. Dental anxiety ratings by the children and parents were correlated with the behaviour assessment of the dentist. Statistical significance was determined at dental anxiety level and the child's self report (t=0.389; p=0.689). However, the mothers were able to rate their child's dental anxiety level better than the fathers (r=0.497 and pdental anxiety and general anxiety levels (r=0.58, pdental anxiety level (r=0.10, p>0.05). The Nigerian mothers could be relied upon to make objective assessment of their child's dental anxiety. General anxiety appears to play a significant role in dental anxiety development in Nigerian children who appear to behave well in the dental chair despite their reported dental anxiety levels.

    Ischemic brain damage has been reported in healthy patients after beach chair position for surgery due to cerebral hypoperfusion. Near-infrared spectroscopy has been described as a non-invasive, continuous method to monitor cerebral oxygen saturation. However, its impact on neurobehavioral outcome comparing different anesthesia regimens has been poorly described. In this prospective, assessor-blinded study, 90 patients undergoing shoulder surgery in beach chair position following general (G-group, n=45) or regional anesthesia (R-group; n=45) were enrolled to assess the prevalence of cerebral desaturation events comparing anesthesia regimens and their impact on neurobehavioral and neurological outcome. Anesthesiologists were blinded to regional cerebral oxygen saturation values. Baseline data assessed the day before surgery included neurological and neurobehavioral tests, which were repeated the day after surgery. The baseline data for regional cerebral oxygen saturation/bispectral index and invasive blood pressure both at heart and auditory meatus levels were taken prior to anesthesia, 5 min after induction of anesthesia, 5 min after beach chair positioning, after skin incision and thereafter all 20 min until discharge. Patients in the R-group showed significantly less cerebral desaturation events (p<0.001), drops in regional cerebral oxygen saturation values (p<0.001), significantly better neurobehavioral test results the day after surgery (p<0.001) and showed a greater hemodynamic stability in the beach chair position compared to patients in the G-group. The incidence of regional cerebral oxygen desaturations seems to influence the neurobehavioral outcome. Regional anesthesia offers more stable cardiovascular conditions for shoulder surgery in beach chair position influencing neurobehavioral test results at 24h.

    Estimation of cerebral perfusion pressure during elective shoulder surgery in the beach chair position is regularly performed by noninvasive brachial blood pressure (NIBP) measurements. The relationship between brachial mean arterial pressure and estimated temporal mean arterial pressure (eTMAP) is not well established and may vary with patient positioning. Establishing a ratio between eTMAP and NIBP at varying positions may provide a more accurate estimation of cerebral perfusion using noninvasive measurements. This prospective study included 57 patients undergoing elective shoulder surgery in the beach chair position. All patients received an interscalene block and general anesthesia. After the induction of general anesthesia, values for eTMAP and NIBP were recorded at 0°, 30°, and 70° of incline. A statistically significant, strong, and direct correlation between NIBP and eTMAP was found at 0° (r = 0.909, P ≤ .001), 30° (r = 0.874, P chair position. Awareness of this phenomenon is important to ensure adequate cerebral perfusion and prevent hypoxic-related injuries. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

    Michael Balint's lead article, "Repeat Prescription Patients: Are They An Identifiable Group?" inaugurated the first issue of Psychiatry in Medicine, Vol. 1, No. 1, 1970. A few years later, this Journal would be renamed International Journal of Psychiatry in Medicine (IJPM). Who is this author of over 165 papers, 10 books, practicing psychoanalyst from 1926 to 1970, director of the Budapest Psychoanalytic Institute from 1935 to 1939, consultant at the Tavistock Clinic from 1948 to 1961, President of the British Psycho-Analytical Society from 1968 to 1970, literary executor of Sandor Ferenczi, a foremost theorist of object relations, and international educator and statesman for general practitioners? We would like to review for you some of the formative experiences in Michael's life that wedded psychoanalysis and general practice, and how they contributed to his major educational commitment over 40 years to furthering the understanding and integration of psychosocial factors in the practice of primary healthcare as experienced by doctors all over the world. We would also like to highlight some of his major insights and see to what extent they are incorporated in contemporary medical education and practice. We believe that some of his major insights have been neglected and others have been further amplified and extended. Our intention is to speak not only to medical students who desire to pursue medicine related directly to patient care but as well to seasoned practitioners who continue on a daily basis to care for individual patients and their families.

    Isaac, Carol; Griffin, Lindsay; Carnes, Molly

    2010-03-01

    Concurrent with the evolving role of the department chair in academic medicine is the entry of women physicians into chair positions. Because implicit biases that stereotypically masculine behaviors are required for effective leadership remain strong, examining faculty members' perceptions of their chair's leadership in medical school departments with women chairs can provide insight into the views of women leaders in academic medicine and the complex ways in which gender may impact these chairs' leadership style and actions. We conducted semistructured interviews with 13 male and 15 female faculty members representing all faculty tracks in three clinical departments chaired by women. Inductive, qualitative analysis of the subsequent text allowed themes to emerge across interviews. Four themes emerged regarding departmental leadership. One dealt with the leadership of the previous chair. The other three described the current chair's characteristics (tough, direct, and transparent), her use of communal actions to help support and mentor her faculty, and her ability to build power through consensus. Because all three chairs were early in their tenure, a wait and see attitude was frequently expressed. Faculty generally viewed having a woman chair as an indication of positive change, with potential individual and institutional advantages. This exploratory study suggests that the culture of academic medicine has moved beyond questioning women physicians' competence to lead once they are in top organizational leadership positions. The findings are also consonant with experimental research indicating that women leaders are most successful when they pair stereotypic male (agentic) behaviors with stereotypic female (communal) behaviors. All three chairs exhibited features of a transformational leadership style and characteristics deemed essential for effective leadership in academic medicine.

  18. The Strategic Value of Succession Planning for Department Chairs.

    Science.gov (United States)

    Rayburn, William; Grigsby, Kevin; Brubaker, Linda

    2016-04-01

    Most faculty who aspire to be department chairs are unaware of succession processes at their institution. This Commentary highlights the importance of succession planning, emphasizing the general need for transparency. Succession planning provides institutional leaders the opportunity to optimize, renew, and revitalize their organization by ensuring successful leadership transitions. In contrast to leadership pathways in the military, corporate business, and hospital administration, planned succession of medical school department chairs has received little attention. Different approaches to succession planning are essential for emergency and planned transitions. Emergency succession plans should be in place at all times, regularly revisited, and modified as needed. Department chairs should begin considering their planned succession between one and five years after their initial appointment. The succession discussion between a chair and medical school dean requires cautious, thoughtful, and open discussions. Intradepartmental annual faculty performance evaluations permit the chair to mentor potential successors in acquiring future-oriented, institution-based leadership qualities necessary to be considered for a future department chair position. If health and time permit, the successful chair should remain in his or her current position until a successor is named or, preferably, is in place. Appointment of an interim chair as part of succession planning can be useful for on-the-job training of an internal candidate, yet awkwardness might ensue if there is more than one internal candidate.Succession development offers the great advantage of maintaining smooth organizational performance while optimizing talent management and exploring opportunities for transitioning individuals into leadership roles.

    Full Text Available Michael Moore is famous and popular in many European countries, where he is seen as a critic of American culture. However, his main thesis, which is repeatedly expressed in his films and books, does not primarily criticize American popular culture or political tradition. Rather, this article argues that Moore’s thought may best be analysed through the American tradition of radicalism, whose origin dates back to Thomas Paine. Obviously, Moore is a contemporary radical who uses the modern media to reach as many people as possible. Yet some aspects of his rationale are surprisingly close to 18th century American radicalism.

  14. Ankle-brachial blood pressure differences in the beach-chair position of the shoulder surgery.

    Choi, Jae Chan; Lee, Jong-Hyuk; Lee, Young-Don; Kim, Soon Yul; Chang, Sei-Jin

    2012-12-01

    During shoulder surgery, blood pressure is frequently measured at the ankle. Anesthetic complications may result when ankle blood pressure is higher than brachial blood pressure and anesthesiologists misinterpret ankle blood pressure as brachial blood pressure. Therefore, we investigated whether ankle blood pressure is significantly higher than brachial blood pressure before anesthesia induction, during induction, after tracheal intubation, before beach chair position, and in the beach chair position. Thirty patients requiring general anesthesia for shoulder surgery were included in this study. Ankle and brachial blood pressure were simultaneously measured before induction, during induction, after intubation, before beach chair position, and in the beach chair position. Ankle blood pressure was higher than brachial blood pressure before induction, during induction, after intubation, before beach chair position, and in the beach chair position. Ankle-brachial blood pressure differences in the beach chair condition were much higher than in four other conditions. The correlation coefficient between mean ankle-brachial blood pressure differences before the beach chair position and mean ankle-brachial blood pressure differences in the beach chair position was 0.616. Brachial systolic blood pressure could be predicted by regression equations (R(2) = 0.306-0.771). These results suggest that anesthesiologists should consider these ankle-brachial blood pressure differences when monitoring anesthesia in the beach chair position.

    Ross, Warren E; Huang, Karen H C; Jones, Greg H

    2014-05-01

    The success of newly recruited medical school department chairs has become increasingly important for achievement of organizational goals. An effective onboarding program for these chairs can greatly facilitate early success, as well as satisfaction of the new hire with the position and the school. Onboarding programs can include traditional orientation items such as payroll signup and parking details, but should focus heavily on sharing organizational structure, culture, and how things get done. The goals of onboarding will be well served by implementation of three roles in the process. An Orientation Navigator can assist the new chair in the orientation phase, completing new employee documents and navigating the day-to-day challenges of working at the location. A Peer Mentor, generally a sitting chair, serves as both "buddy" and mentor, providing moral support as well as ensuring that the new chair gains an understanding of the people and processes important for getting things done. A Transition Mentor serves over a longer term as a sounding board and coach outside the peer group, assisting in a variety of ways to promote the chair's growth, development, and success as a leader. Finally, any onboarding process is significantly compromised without the active participation of the dean, meeting regularly with the chair to clarify expectations, promote assimilation, and solve problems. Successful onboarding begins with a mindfulness of the needs of the newly hired chair, and a well-designed and well-implemented plan will have wide-ranging benefits for the chair and the organization.

  1. Chair-based fidgeting and energy expenditure.

    Koepp, Gabriel A; Moore, Graham K; Levine, James A

    2016-01-01

    Sedentariness is associated with chronic health conditions, impaired cognitive function and obesity. Work contributes significantly to sedentariness because many work tasks necessitate sitting. Few sustained solutions exist to reverse workplace sedentariness. Here, we evaluated a chair and an under-table device that were designed to promote fidgeting while seated. Our hypothesis was that an under-table leg-fidget bar and/or a fidget-promoting chair significantly increased energy expenditure. We compared these devices with chair-based exercise and walking. We measured energy expenditure and heart rate in 16 people while they sat and worked using a standard chair, an under-desk device that encourages leg fidgeting and a fidget-promoting chair. We compared outcomes with chair-based exercise and walking. Energy expenditure increased significantly while using either an under-table leg-fidget bar or a fidget-promoting chair, when compared to the standard office chair (standard chair, 76±31 kcal/hour; leg-fidget bar, 98±42 kcal/hour (pchair, 89±40 kcal/hour (p=0.03)). However, heart rate did not increase significantly in either case. Bouts of exercise performed while seated provided energetic and heart rate equivalency to walking at 2 mph. Chairs and devices that promote fidgeting can increase energy expenditure by ∼20-30% but not increase heart rate. Dynamic sitting may be among a lexicon of options to help people move more while at work.

    Although there is a considerable literature on transition of faculty members to the position of department chair, there is a dearth of publications about transitioning from the chair to other activities including retirement. The Association of Pathology Chairs senior fellows (all of whom are former chairs of academic departments of pathology) made this topic a focus of discussion at the Association of Pathology Chairs 2016 Annual Meeting. Of the 33 senior fellows engaged in this discussion, following their time as chairs, a small majority (18) transitioned to other administrative posts within or outside the university, while the others either returned to the active faculty (7) or retired (8). The motivating factors and influences for transitioning from the chair were probed along with the processes used in executing the transition, such as the development of transition plans. The reasons for selecting the specific type of postchair activity were also investigated. There was extraordinary diversity in the type of post-chair activities pursued. To our knowledge, no other medical specialty has examined these issues, which may be potentially relevant for the career planning of active chairs. PMID:28725780

    The objective of this study was to compare demographic injury and treatment characteristics of hospitalized pediatric cases of falls from chair lifts to cases of other ski and snowboarding injuries and identify potential interventions for preventing falls from chair lifts. Retrospective query of the trauma registry of Utah's only pediatric trauma center for children younger than 18 years requiring hospitalization for a ski or snowboarding injury from November 2004 to February 2014. There were 443 cases of hospitalized ski and snowboarding injuries during the study period. Twenty-nine cases (7%) fell from height while riding a chair lift. Children falling from chair lifts were more likely to be younger (6.9 years vs 12.1, P chair lift falls with a significant injury (abbreviated injury scale, ≥3) was lower extremity (4/29, all femur fractures). Patient age discriminated chair lift falls well (area under the receiver operating characteristic curve, 0.87) with age of 7 years and below predicting chair lift fall with a sensitivity of 76% and a specificity of 91%. Injuries requiring hospitalization after falls from chair lifts occur at regulated facilities and are more common in younger female children when compared with other ski and snowboarding injuries. Interventions for reducing falls from chair lifts may be most effective applied to children 7 years and younger.

  7. Automated chair-training of rhesus macaques.

    Neuroscience research on non-human primates usually requires the animals to sit in a chair. To do this, typically monkeys are fitted with collars and trained to enter the chairs using either a pole, leash and jump cage. Animals may initially show resistance and risk injury. We have developed an automated chair-training method that minimizes restraints to ease the animals into their chairs. We developed a method to automatically train animals to enter a primate chair and stick out their heads for neckplate placement. To do this, we fitted the chairs with Arduino microcontrollers coupled to a water-reward system and touch- and proximity sensors. We found that the animals responded well to the chair, partially entering the chair within hours, sitting inside the chair within days and allowing us to manually introduce a door and neck plate, all within 14-21 sessions. Although each session could last many hours, automation meant that actual training person-hours could be as little as half an hour per day. The biggest advantage was that animals showed little resistance to entering the chair, compared to monkeys trained by leash pulling. This automated chair-training method can take longer than the standard collar-and-leash approach, but multiple macaques can be trained in parallel with fewer person-hours. It is also a promising method for animal-use refinement and in our case, it was the only effective training approach for an animal suffering from a behavioral pathology.

  8. Axiology, the Subject and the Chair

    This article addresses two gaps in the literature related to science department chairs: the axiological relationship between the chair and science, the subject, and the perceptions of the chair with respect to teaching and learning within their departments. In this work, axiology is used to understand how the chair's values toward the subject influenced his own perceived capacity to lead learning within his department in a reformed discourse. A narrative inquiry methodology was used to consider the chair's experiences in the development of his identify over his life span in the form of two stories: (1) the relationship between the chair and science, the subject, and (2) the perceptions of the chair with regards to teacher learning within the department. The findings revealed that the work and career of the chair in this study were authored by strong elements of personal continuity and points of stability around the valuing of science, the subject, even as this valuing evolved from being more focused on epistemic values early in his career, to being more concerned with universal values connected to his legacy and his department later in his career.

This new and most welcome contribution to global academic writing and contemporary legal criticism, should be of the greatest interest outside Qatar, if only for its provenance. The State of Qatar has become widely known and respected for its vision, its progressive outlook, and its determination to look beyond Arab culture and traditions for new ways of working with the rest of the world for the good of the region as a whole. It has made a bold commitment to engage with the accepted legal principles and processes that have served the needs of global mercantile and commercial activity so well over the last two centuries. his is demonstrated by the generous support given by His Highness the Emir to the Qatar Law Forum 2009, to be repeated in May this year, in which jurists and lawyers of great eminence are brought together in Doha to expound, explain and exchange ideas upon the importance of the rule of law, the universal key to principled and effective government, and the protection of individual freedom and dignity.

    Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The beach chair position is a reliable, safe, and effective position to perform nearly all types of shoulder arthroscopic procedures. The advantages of the beach chair position include the ease of setup, limited brachial plexus stress, increased glenohumeral and subacromial visualization, anesthesia flexibility, and the ability to easily convert to an open procedure. This position is most commonly used for rotator cuff repair, subacromial decompression, and superior labrum anterior-to-posterior repair procedures. To perform arthroscopy surgery in the beach chair position successfully, meticulous care during patient positioning and setup must be taken. In this Technical Note, we describe the necessary steps to safely and efficiently prepare patients in the beach chair position for arthroscopic shoulder surgery.

Another suggestion regarding integration between HRP Elements/Projects is that the HRP convene a meeting of scientists who have a good record of pursuing multidisciplinary/integrative research in the general areas that are relevant to the HRP; identify those that are of high priority; and then support research on those, giving priority to multidisciplinary/integrative teams in which all relevant HRP disciplines are represented. Some of these teams may be already established and functioning within the HRP; others might be organized in response to NASA's research announcements. Lastly, the Chair (+1) SRP felt that there were two overarching issues that spanned across all of the HRP Elements/Projects. The first, which was discussed in great detail, is access to the astronaut medical records, psychological as well as physical. New research will not be useful unless one has access to what has been done, what has worked, and what has not worked. Second is access to records of what medications are being taken by the astronauts while in-flight. The Chair (+1) SRP feels that there needs to be good medical reconciliation to know beginning to end what is happening healthwise to the astronauts.

    [Purpose] We assessed the effects of a suspension seat support chair on the trunk flexion angle and gluteal pressure during computer work. [Subjects] Ten males were recruited. [Methods] The suspension seat support was developed to prevent abnormal gluteal pressure and a slumped sitting posture during computer work. The gluteal pressure was measured with a TekScan system and the trunk flexion angle was measured with a video camera, to compare the differences between a general chair and the suspension seat support. [Results] The gluteal peak pressures were decreased significantly in the suspension seat support versus the general chair. The trunk flexion angle was also decreased significantly in the suspension seat support compared with the general chair. [Conclusions] This study suggests that the suspension seat support chair contributes to preventing abnormal gluteal pressure and a slumped sitting posture.

    Optically active, tertiary amine Lewis bases react with unsaturated acid chlorides to deliver chiral, α,β-unsaturated acylammonium salts. These intermediates participate in a catalytic, enantioselective, three-component process delivering bi- and tricyclic β-lactones through a Michael-Michael-aldol-β-lactonization. In a single operation, the described multicomponent, organocascade process forms complex bi- and tricyclic β-lactones by generating four new bonds, two rings, and up to four contiguous stereocenters. In the racemic series, yields of 22-75% were achieved using 4-pyrrolidinopyridine as Lewis base. In the enantioselective series employing isothiourea catalysts, a kinetic resolution of the initially formed racemic Michael adduct appears operative, providing yields of 46% to quantitative (based on 50% max) with up to 94:6 er. Some evidence for a dynamic kinetic asymmetric transformation for tricyclic-β-lactone 1d was obtained following optimization (yields up to 61%, 94:6 er) through a presumed reversible Michael.

    The noise caused by the movement of users on their chairs in the work environment may indicate structural weaknesses and risk, and still significantly reduce productivity by increasing employees stress level. By understanding the activities to be developed in a work place one may understand what should be necessary to a good development, thereafter a search for improvement of labor activity with the aim of better use of resources in the operation of product use may be done. The analysis of the incremental variation of noise in professional chairs aims to identify its origin and the time the emission of noise starts during the period of use, its development and the major causative agents. Determining the characteristics of the sound of different materials and adjustments mechanisms of the chair can determine how different materials interact with each other. The measurement of these noises in an acoustic isolated room using directional microphones, if recorded and analyzed properly makes it possible to investigate and orientate to suspect elements in order to propose solutions and identify the quality of other similar chairs. Based on the results recommendations can be established for the orientation of users, managers and people responsible for the acquisition of the products, inducing them to review the employment of materials and the choice of the processes of production. These aspects are not covered in the Brazilian ergonomics norms and standards in the use of chairs.

    2016-11-01

    Pediatric general and subspecialty care requires continuous effort to maintain knowledge and competencies in clinical practice. Equally important are efforts by investigators and educators to maintain knowledge and competencies in the conduct of research and training. The Association of Medical School Pediatric Department Chairs initiated a survey in July 2015 to define principles of lifelong learning in pediatric medicine and determine the approaches and strategies used by chairs to assess knowledge and competence across the care, research, and teaching missions. A total of 101 of 142 chairs (71%) completed the survey. Six of 7 proposed principles were endorsed by 84% to 96% of Association of Medical School Pediatric Department Chairs members. The focus areas included individual accountability, individually relevant activities, use of evidence-based guidelines/national standards, gaining cognitive expertise, learning as a continuous effort, affordability, and focus on individual understanding. The chairs endorsed a requirement for evidence of lifelong learning, competence, and compliance by all faculty members in clinical (n = 89 [88%]), research (n = 63 [62%]), and educational (n = 85 [84%]) practice. The survey identified the strategies to assess lifelong learning and faculty competence and compliance in clinical, research, and educational roles. Across missions, chairs endorsed an expectation for individual responsibility supplemented by formal evaluation practices and institutional and regulatory office oversight. While chairs endorsed an important role for the American Board of Pediatrics in assessing and verifying lifelong learning, knowledge, and competence in general and specialty certification, most (n = 91 [90%]) endorsed a need to revise current board requirements to better emphasize closing gaps in knowledge and using approaches that are evidence-based. This study provides the perspectives of pediatric department chairs on principles

  11. Principles of Chemistry (by Michael Munowitz)

    Kovac, Reviewed By Jeffrey

    2000-05-01

    At a time when almost all general chemistry textbooks seem to have become commodities designed by marketing departments to offend no one, it is refreshing to find a book with a unique perspective. Michael Munowitz has written what I can only describe as a delightful chemistry book, full of conceptual insight, that uses a novel and interesting pedagogic strategy. This is a book that has much to recommend it. This is the best-written general chemistry book I have ever read. An editor with whom I have worked recently remarked that he felt his job was to help authors make their writing sing. Well, the writing in Principles of Chemistry sings with the full, rich harmonies and creative inventiveness of the King's Singers or Chanticleer. Here is the first sentence of the introduction: "Central to any understanding of the physical world is one discovery of paramount importance, a truth disarmingly simple yet profound in its implications: matter is not continuous." This is prose to be savored and celebrated. Principles of Chemistry has a distinct perspective on chemistry: the perspective of the physical chemist. The focus is on simplicity, what is common about molecules and reactions; begin with the microscopic and build bridges to the macroscopic. The author's perspective is clear from the organization of the book. After three rather broad introductory chapters, there are four chapters that develop the quantum mechanical theory of atoms and molecules, including a strong treatment of molecular orbital theory. Unlike many books, Principles of Chemistry presents the molecular orbital approach first and introduces valence bond theory later only as an approximation for dealing with more complicated molecules. The usual chapters on descriptive inorganic chemistry are absent (though there is an excellent chapter on organic and biological molecules and reactions as well as one on transition metal complexes). Instead, descriptive chemistry is integrated into the development of

    To compare the different techniques used by paramedics in handling an emergency evacuation chair and to identify themore ergonomically favourable technique, based on an analysis ofmuscular activity using surface electromyography. The trial was based on descending stairs, through four possible arrangements for the same transport operation, where the study variables were: worker anthropometrics (5th and 95th percentiles, corresponding to the extremes of the normal height-weight distribution curve), worker location during chair transport (upper or lower end of the chair), and the position of the individual at the lower end (facing front or backwards during descent). For both workers participating in the study, the more favourable working position during chair descent was at the lower end of the chairwhile facing forward, as this was associated with less muscular activity. In general, physical demands on the various muscles studied was greater for the worker corresponding to the 5th percentile (i.e., lower height-weight), except for the paravertebral musculature which, for certain maneuvers involving manipulation was significantly greater than the 95th percentile. When descending stairs while transporting an emergency evacuation chair, the position involving least muscular activity is located at the lower end of the chair, and descending while facing forwards.

    To explore the role played by human research ethics committees (HRECs) with regard to the fair inclusion of men and women in Australian clinical research. Semi-structured face-to-face and telephone interviews with 25 chairs (or their nominees) of Australian HRECs between 9 June 2006 and 24 January 2007. Chairs' views about the role of HRECs in identifying sex discrimination, monitoring the inclusion of men and women in clinical research, and interpreting and applying National Health and Medical Research Council (NHMRC) guidelines relating to fair inclusion in research. In general, HRECs do not take an active role in monitoring the sex of research participants. They do not ask for or often receive information about the sex of participants. Most HREC chairs did not believe that sex discrimination in research is currently a significant or widespread problem, and were confident that their committees would be able to identify arbitrary exclusion of either men or women from research. However, many chairs expressed a lack of familiarity with debates about sex equity in research. Most chairs were unaware that anti-sex-discrimination legislation could apply to research. "Fair inclusion" was interpreted in a number of ways by chairs, but most frequently that the sex balance among research participants should reflect the sex distribution in the community of the condition under investigation. Chairs said their committees would be reluctant to reject a research protocol on the grounds that the sex balance among participants was perceived to be unfair. Views about, and expertise on, sex equity in research vary among chairs of HRECs. Many HRECs require further guidance about the appropriate standards for fair inclusion of men and women in Australian clinical research.

  17. Jumping From a Chair is a More Sensitive Measure of Power Performance In Older Adults Than Chair Rising.

    2016-01-01

    Background/Study Context: The study estimates the reliability of peak velocity and peak power during chair rising and chair jumping tests and their ability to discriminate between different age and physical activity level groups. Physically active and sedentary individuals (N = 262) of different ages (young: 22.9 ± 2.0 years, range: 21-25 years; older: 63.1 ± 1.8 years, range: 61-65 years) performed, in random order, chair rising and chair jumping tests on a force plate. Randomly selected young subjects performed both tests repeatedly on two different occasions separated by 1 week. From the sitting position with the arms crossed on the chest, they either stand up completely (chair rising test), or jump as high as possible (chair jumping test). The test-retest reliability of peak power and peak velocity during chair rising as well as chair jumping was excellent, with high intraclass correlation coefficients (ICCs; .90-.98) and low standard error of measurement (SEM; 7.0-9.1%). Post hoc analysis revealed significant differences in peak power and peak velocity between the sedentary and physically active young and older subjects. However, greater coefficients of variation for both parameters were found for chair jumping than chair rising (21.1-40.2% vs. 11.0-15.2%). Additionaly, there were moderate correlations of peak power and peak velocity between chair rising and chair jumping (r = .42-.49). There were greater within- and between-group differences in peak force and peak power and a steeper increase in their values during the initial phase of chair jumping than chair rising. Both chair rising and chair jumping tests provide reliable data and are valid indicators of lower body power in young and older adults. However, jumping from a chair is a more sensitive measure of strength and power performance than chair rising.

Using Generalized Least Square (GLS) method for regression analysis, the results show that holding either tier-1 or tier- 2 of CRC significantly and positively results in conducting research with higher impact. This finding, however, does not necessarily imply that the others are the lesser scientists. (Author)

    2004-12-01

    Michael James Ledlow died on 5 June 2004 from a large, unsuspected brain tumor. Since 2000 he had been on the scientific staff of the Gemini Observatory in La Serena, Chile, initially as a Science Fellow and then as a tenure-track astronomer. Michael was born in Bartlesville, Oklahoma on 1 October 1964 to Jerry and Sharon Ledlow. He obtained his Bachelor Degree in astrophysics at the University of Oklahoma in 1987 and attended the University of New Mexico for his graduate work, obtaining his PhD while studying Galaxy Clusters under Frazer Owen in 1994. From 1995-1997 Michael held a postdoctoral position with Jack Burns at New Mexico State University where he used various astronomical facilities including the VLA and Apache Point Observatory to study distant galaxies. From 1998-2000 Michael rejoined the Physics and Astronomy Department at the University of New Mexico where he was a visiting professor until he moved on to Gemini. At the Gemini Observatory, Mike shared in the excitement, hard work and many long days and nights associated with bringing on-line a major new astronomical facility and its instrumentation. Following its commissioning he assisted visiting observers, supported and took data for many more remote users via the queue system, and for each he showed the same care and attention to detail evident in his own research to ensure that all got the best possible data. His research concentrated on the radio and optical properties of galaxy clusters, especially rich Abell clusters such as A2125, on luminous radio galaxies, including the detection of a powerful double radio source in the "wrong sort of galaxy," the spiral system 0313-192, and on EROs (extremely red objects), dusty galaxies barely detectable at optical wavelengths. Michael thoroughly enjoyed living in Chile and enthusiastically immersed himself in the culture of his surroundings. He and his family were actively involved with the International English Spanish Association in La Serena. He had a

    Many of the metal casting processes are still empirical in nature. Many others are deeply rooted in mathematics and therefore, suitable for modeling. Science of casting and solidification is a major technical asset for foundry operations and of extreme importance in understanding different length scales microstructural changes and evolution as well as developing new processes and materials. In his attempt to describe combinations of solidification theory, research results and industrial practice, Professor Doru Michael Stefanescu (ASM Fellow, 1997) has made tremendous contributions to the field. Many of his views on casting and solidification are valued as important impacts within professional environments such as TMS and ASM International. He has written many articles for the ASM Handbook series on subjects including basic metallurgy of cast iron, compacted graphite irons, solidification, thermodynamic properties of iron-base alloys, and computational modeling. He was also Volume Chair for Volume 15: Casting, of the 9th Edition Metals Handbook.

    2017-10-01

    Dynamic sitting approaches have been advocated to increase seated energy expenditure with the view of lessening the sedentary nature of the task. This study compared energy expenditure (EE) and overall body discomfort on a novel dynamic chair with a standard office chair. Fifteen pain-free participants completed a DVD viewing task on both chairs in a randomised order. Energy expenditure and discomfort were collected simultaneously. Linear mixed models were used to analyse steady-state EE recorded on each of the chairs. Differences in discomfort were analysed using Wilkoxon Signed Rank Tests. Sitting on the novel dynamic chair significantly (p = 0.005) increased energy expenditure compared to a standard office chair. The discomfort experienced was mild overall, but was significantly greater on the dynamic chair (p = 0.004). Whilst the EE was seen to be significantly higher on the dynamic chair, the MET values are still below 1.5 METS. Thus, the use of a dynamic chair does not seem to be the most effective measure to prevent sedentary behaviour. Practitioner Summary: Sitting on a dynamic chair increased energy expenditure compared to sitting on a standard office chair among pain-free participants. Whilst the EE was seen to be significantly higher on the dynamic chair, the MET values are still below 1.5 METS (low level EE).

Neuropraxia of the great auricular nerve (GAN is an uncommon complication of shoulder surgery, with the patient in the beach chair position. We report a case of great auricular neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. In this case, an arthroscopic approach was taken, under regional anesthesia with sedation in the beach chair position. The GAN, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. We recommend that for the procedures of the beach chair position, the auricle be protected and covered with cotton and gauze to avoid direct compression and the position of the head and neck be checked and corrected frequently.

    Hybrid supercapacitors that follow a "rocking-chair"-type mechanism were developed by coupling divalent metal and activated carbon electrodes in nonaqueous electrolytes. Conventional supercapacitors require a large amount of electrolyte to provide a sufficient quantity of ions to the electrodes, due to their Daniell-type mechanism that depletes the ions from the electrolyte while charging. The alternative "rocking-chair"-type mechanism effectively enhances the energy density of supercapacitors by minimizing the necessary amount of electrolyte, because the ion is replenished from the metal anode while it is adsorbed to the cathode. Newly developed nonaqueous electrolytes for Mg and Zn electrochemistry, based on bis(trifluoromethylsulfonyl)imide (TFSI) salts, made the metal hybrid supercapacitors possible by enabling reversible deposition on the metal anodes and reversible adsorption on an activated carbon cathode. Factoring in gains through the cell design, the energy density of the metal hybrid supercapacitors is projected to be a factor of 7 higher than conventional devices thanks to both the "rocking-chair"-type mechanism that minimizes total electrolyte volume and the use of metal anodes, which have substantial merits in capacity and voltage. Self-discharge was also substantially alleviated compared to conventional supercapacitors. This concept offers a route to build supercapacitors that meet dual criteria of power and energy densities with a simple cell design.

    Full Text Available The purpose of this article was to identify the Jepara chairs based on its style and period. Qualitative research such as doing interviews with the Jepara chairs observer, observation to some centres and workshops of Jepara chairs, literature study from various books consisting the style and process of Jepara chairs production were conducted. The identification of Jepara chairs started with Islamic and Hinduism influence in the 16th to the 17th century when the missionary and sailor from Portuguese entered Java until the style of Jepara chair in the 20th century. The alteration that mirrors the changes in socio-cultural aspect was being analysed as the style foundation that was used periodically in the making of the Jepara chairs. The categories a chair to have a Jepara style is a chair made by the craftsman in Jepara that, includes local factors both technically and material based that is combined with foreign culture, religion, and designs that brought at the time the chairs have been made. This research finds that chairs with Jepara style are a combination of the international world with a glimpse of local wisdom, with a touch of the maker’s personality that makes it unique and a bit different with its origin style.

    2014-02-01

    The authors provide a transcription, translation, and evaluation of nine newly discovered letters from the alchemist Michael Maier (1568-1622) to Gebhardt Johann von Alvensleben (1576-1631), a noble landholder in the vicinity of Magdeburg. Stemming from the final year of his life, this correspondence casts new light on Maier's biography, detailing his efforts to secure patronage amid the financial crisis of the early Thirty Years' War. While his ill-fated quest to perfect potable gold continued to form the central focus of his patronage suits, Maier also offered his services in several arts that he had condemned in his printed works, namely astrology and "supernatural" magic. Remarks concerning his previously unknown acquaintance with Heinrich Khunrath call for a re-evaluation of Maier's negotiation of the discursive boundaries between Lutheran orthodoxy and Paracelsianism. The letters also reveal Maier's substantial contribution to a work previously ascribed solely to the English alchemist Francis Anthony.

    2017-03-23

    Asymmetric catalysis for chiral compound synthesis is a rapidly growing field in modern organic chemistry. Asymmetric catalytic processes have been indispensable for the synthesis of enantioselective materials to meet demands from various fields. Michael addition has been used extensively for the construction of C-C bonds under mild conditions. With the discovery and development of organo- and metal-catalyzed asymmetric Michael additions, the synthesis of enantioselective and/or diastereoselective Michael adducts has become possible and increasingly prevalent in the literature. In particular, metal-catalyzed asymmetric Michael addition has been employed as a key reaction in natural product synthesis for the construction of contiguous quaternary stereogenic center(s), which is still a difficult task in organic synthesis. Previously reported applications of metal-catalyzed asymmetric Michael additions in natural product synthesis are presented here and discussed in depth. © 2017 Wiley-VCH Verlag GmbH & Co.

  1. Is chair rise performance a useful measure of leg power?

    Science.gov (United States)

    Hardy, Rebecca; Cooper, Rachel; Shah, Imran; Harridge, Stephen; Guralnik, Jack; Kuh, Diana

    2010-01-01

    Chair rise performance, which is simple to assess in a home or clinic setting, has been used as a method of predicting leg power deficit in older adults. More recently, chair rise performance has been assessed in younger populations as a baseline for assessment of subsequent age-related declines in function and power. However, as rising from a chair repeatedly not only requires lower limb strength and power but also good balance and coordination, it may not be purely a measure of leg power especially among these younger, well functioning groups who are yet to experience agerelated declines and deficits in function. The aim of this study was to assess whether chair rise performance can be considered as a predictor of leg power, and hence of deficits in this, in men and women in mid-life. We assessed the relationship of chair rise performance with leg extensor power (LEP), measured using the Nottingham Power Rig (NPR), and with standing balance performance. LEP was measured in a clinic setting in a sub-sample of 81 men and 93 women from the MRC National Survey of Health and Development, a nationally representative cohort born in Britain in 1946. The time taken to rise from a chair 10 times and standing balance time were assessed during home visits at the same age. Increasing LEP was associated with better chair rise performance among those who completed 10 chair rises in ≥15 seconds, after adjustment for body size (p=0.008). Better standing balance performance was associated with better chair rise performance in men, but not women. That LEP and standing balance are both related to chair rise time in men suggests that chair rise time should not be thought of purely as a proxy measure of leg power in middle-aged populations. This has implications for longitudinal studies which want to study age-related decline in chair rise performance.

    2016-01-01

    Although there is a considerable literature on transition of faculty members to the position of department chair, there is a dearth of publications about transitioning from the chair to other activities including retirement. The Association of Pathology Chairs senior fellows (all of whom are former chairs of academic departments of pathology) made this topic a focus of discussion at the Association of Pathology Chairs 2016 Annual Meeting. Of the 33 senior fellows engaged in this discussion, following their time as chairs, a small majority (18) transitioned to other administrative posts within or outside the university, while the others either returned to the active faculty (7) or retired (8). The motivating factors and influences for transitioning from the chair were probed along with the processes used in executing the transition, such as the development of transition plans. The reasons for selecting the specific type of postchair activity were also investigated. There was extraordinary diversity in the type of post-chair activities pursued. To our knowledge, no other medical specialty has examined these issues, which may be potentially relevant for the career planning of active chairs.

  3. Obituary: Michael John Klein, 1940-2005

    Gulkis, Samuel

    2006-12-01

    Michael John Klein died on 14 May 2005 at home in South Pasadena, California. The cause of death was tongue cancer that metastasized to the lungs. He was a non-smoker. Mike was a passionate radio astronomer, a trusted astronomical observer, an educator and a family man. Mike was born on 19 January 1940 in Ames, Iowa, the son of Florence Marie (Graf) and Fred Michael Klein. His mother was a homemaker, and his father was a banker. Mike had two older sisters, Lois Jean (Klein) Flauher and Marilyn June (Klein) Griffin. In 1962, Mike married his high school sweetheart Barbara Dahlberg, who survives him along with their three children, Kristin Marie (Klein) Shields, Michael John Klein Jr., Timothy Joel Klein, and six grandchildren. Mike developed a love for astronomy early in his life, and credited an early morning, newspaper-delivery route that he had at age twelve, which took him outside well before sunrise. He told family members that as he walked along his route, he stared into the sky and wondered what everything was. He studied sky charts, located stars, and began to understand how the planets shifted their positions relative to the stars each day. Another big influence in Mike's life was his brother in-law, Jim Griffin. Jim helped Mike understand that his passion for science did not have to remain a hobby, but could and should become a career. Jim's encouragement led Mike to attend Iowa State University in Ames, where he earned a BS in electrical engineering in 1962. Mike then started graduate school in electrical engineering at Michigan State, but after one semester transferred to the University of Michigan, Ann Arbor, where he earned an MS (1966) and PhD (1968) in astronomy. His doctoral dissertation, under the direction of Professor Fred Haddock, was based on extensive observations of the planets and examined the physical and thermal properties of planetary atmospheres and surfaces. Mike was awarded a Resident Research Associate position at JPL by the National

  4. Secondary School Department Chairs Leading Successful Change

    Directory of Open Access Journals (Sweden)

    Julie Ann Gaubatz

    2015-12-01

    Full Text Available A foundational understanding within education leadership literature is that education leaders are expected to guide reform efforts within school. This expectation mirrors organizational development literature that describes leaders as individuals who constructively institute change within their organizations. Although leadership and change are portrayed as codependent, no scholarship has linked change models with leadership theories. This article describes a multiple case study that explored the relationship between leadership behaviors and the change process through secondary school department chair stories of change. From this analysis, a clearer picture emerged that illustrates how leaders with little control over decisions implement change. Findings included distinct connections between CREATER change process stages and the Leadership Grid. Suggestions as to how education leaders should approach change attempts within their schools are discussed.

  5. Women chairs in academic medicine: engendering strategic intuition.

    2015-01-01

    Because stereotypically masculine behaviors are required for effective leadership, examining female chairs' leadership in academic medicine can provide insight into the complex ways in which gender impacts on their leadership practices. The paper aims to discuss this issue. The author interviewed three female clinical chairs and compared the findings to interviews with 28 of their faculty. Grounded theory analysis of the subsequent text gathered comprehensive, systematic, and in-depth information about this case of interest at a US top-tier academic medical center. Four of five themes from the faculty were consistent with the chair's narrative with modifications: Prior Environment (Motivated by Excellence), Tough, Direct, Transparent (Developing Trust), Communal Actions (Creating Diversity of Opinion), and Building Power through Consensus (an "Artful Exercise") with an additional theme, the Significance (and Insignificance) of a Female Chair. While faculty members were acutely aware of the chair's gender, the chairs paradoxically vacillated between gender being a "non-issue" and noting that male chairs "don't do laundry." All three female chairs in this study independently and explicitly stated that gender was not a barrier, yet intuitively used successful strategies derived from the research literature. This study suggests that while their gender was highlighted by faculty, these women dismissed gender as a "non-issue." The duality of gender for these three female leaders was both minimized and subtly affirmed.

    2015-10-01

    [Purpose] This study was designed to test the effects of the Assistant Chair-Desk System (ACDS), which can reduce the forward tilt of the neck and trunk and the level of fatigue during long lasting study in the sitting position. [Subjects] Fourteen middle school students and 14 college students of mixed gender participated in this study. [Methods] Fatigue level, the trapezius muscle, and the forward tilt angle of the head and trunk as well as distance factors were assessed before after using a normal chair-desk system (NCDS) and the ACDS for 120 minutes. [Results] There was an interaction effect in the angle and length of the neck from the sitting posture changes after 2 hours of studying using the NCDS and ACDS. There were also significant differences in the fatigue levels, hip joint angles and the lengths from the head according to the main effects of the chair-systems. [Conclusion] The studying position while using the ACDS was determined to prevent significant fatigue levels of the muscle and body, provide support to the head, by limiting the forward movement of the neck, and prevent forward tilt of the neck and trunk, by enabling the target point and gaze to be closer to the horizontal direction.

    A picture may be worth a thousand words - but a picture of a chair? It’s worth a story all by itself. Over the past year, the "Lonely Chairs at CERN" photography blog has let the chairs do the talking. Along the way, these chairs have inspired and enchanted people across the globe with their honest depiction of the Laboratory.   This lonely chair outside Building 32 was one of the first Rebeca photographed. When CMS physicist Rebeca Gonzalez Suarez created Lonely Chairs at CERN back in April 2014, she was not expecting the immediate reaction it garnered. Within days, the blog had picked up thousands of followers and was featured in Gizmodo and The Guardian. "The response inside CERN was very positive, but the response outside was overwhelming," says Rebeca. "I’ve got a lot of followers who are really into science and are very excited about CERN.

    2003-12-01

    Within the dental setting, historically there has been some concern as to whether cardiopulmonary resuscitation (CPR) can be performed effectively in the dental chair. This study tested the hypothesis that there is no difference in the efficacy of CPR performed in the dental chair or on the floor. Four cycles of two-person CPR were performed by three health professionals on a manikin positioned alternately on the floor and in a dental chair. Ventilation was performed using a Laerdal pocket mask, without oxygen supplementation. Compression and ventilation performance was recorded using a computerized manikin skill meter. Each of the participants was able to achieve a mean cardiac compression depth of between 41 and 50cm, irrespective of the CPR surface. The only statistically significant difference found in expired air resuscitation (EAR) and external cardiac compression performance was that 37 per cent of ventilations performed on the floor were deemed to be too shallow, compared to only 15 per cent in the dental chair (p=0.001). It is possible for those trained in basic life support to perform CPR effectively in the dental chair. Each of the participants agreed that CPR, in particular EAR, was easier to perform when the manikin was in the dental chair compared with the floor. Dentists are encourage to regularly update their CPR knowledge and skills, including the practice of CPR in the dental chair.

    Purpose: The aims of this study were to determine the self-reported prevalence of burnout in chairs of academic radiation oncology departments, to identify factors contributing to burnout, and to compare the prevalence of burnout with that seen in other academic chair groups. Methods and Materials: An anonymous online survey was administered to the membership of the Society of Chairs of Academic Radiation Oncology Programs (SCAROP). Burnout was measured with the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Results: Questionnaires were returned from 66 of 87 chairs (76% response rate). Seventy-nine percent of respondents reported satisfaction with their current positions. Common major stressors were budget deficits and human resource issues. One-quarter of chairs reported that it was at least moderately likely that they would step down in the next 1 to 2 years; these individuals demonstrated significantly higher emotional exhaustion. Twenty-five percent of respondents met the MBI-HSS criteria for low burnout, 75% for moderate burnout, and none for high burnout. Group MBI-HSS subscale scores demonstrated a pattern of moderate emotional exhaustion, low depersonalization, and moderate personal accomplishment, comparing favorably with other specialties. Conclusions: This is the first study of burnout in radiation oncology chairs with a high response rate and using a validated psychometric tool. Radiation oncology chairs share similar major stressors to other chair groups, but they demonstrate relatively high job satisfaction and lower burnout. Emotional exhaustion may contribute to the anticipated turnover in coming years. Further efforts addressing individual and institutional factors associated with burnout may improve the relationship with work of chairs and other department members.

    We report a case of neuropraxia of the 9th, 10th and 12th cranial nerve pairs after arthroscopic rotator cuff repair in the beach chair position. The elements in the medical file seem to exclude an intracranial cause of the lesions and support a mechanical, extracranial cause due to intubation and/or the beach chair position. This clinical case report shows the neurological risks of the beach chair position during arthroscopic shoulder surgery and presents the essential safety measures to prevent these risks.

    Although chair seat height affects the performance of sit-to-stand movement, no previous study has examined the influence of chair seat height on the 30-second chair stand test (CST). Fifty-five community-dwelling older adults (age 70.0 ± 6.3 years) performed the test from the standard height of 43 cm and then from five randomly ordered seat heights from 80 to 120 % of each participant's lower leg length. Chair seat height significantly influences the performance of community-dwelling older adults' 30-s CST (F = 57.50, p  0.95) and between the standard and 90 % conditions (p = 0.353). When comparing the scores between the randomly ordered chair seat heights, all comparisons were significantly different (p Chair seat height's relation to the lower leg length should be considered when interpreting 30-s CST scores. Additionally, it is necessary to optimize the chair seat height when using the 30-s CST as an outcome measure for exercise intervention or to screen for people with weaker lower extremities.

    The goal of our research is to develop a practical vehicle for lower limbs disabled to improve their mobility and health. The most significant mechanical character of the proposed vehicle is that it is driven by the lower limbs of the disabled themselves. We call it as Cycling Chair. Disuse of the lower limbs leads many subsidiary issues on health, deteriorating the whole-body circulation, it is the most serious problem, cases so-called the disuse syndrome. The proposed Cycling Chair solves those problems by using the leg-driven mechanism. In this paper, the mechanism of the Cycling Chair and the way to drive the chair by paraplegics are discussed. Some experimental results are also presented.

  13. Obituary: Michael John Seaton, 1923-2007

    Science.gov (United States)

    Pradhan, Anil; Nahar, Sultana

    2007-12-01

    Professor Michael John Seaton, hailed as the "Father of Atomic Astrophysics," passed away on May 29, 2007. He was one of the few Honorary Fellows of both the American Astronomical Society and the American Physical Society, so honored for his monumental contributions to both physics and astronomy. Mike Seaton was born on January 16, 1923 in Bristol, England. He attended Wallington County High School. But his leftist political activities, even at that stage, led to his expulsion, though he was eventually allowed to matriculate. He enlisted in the Royal Air Force as a navigator during the Second World War, and flew many dangerous missions. His legendary concentration and precision are reflected in the following anecdote. Once after a bombing mission his aircraft was lost in fog over the Alps. Seaton calculated the position and coordinates in flight to guide the aircraft. When the fog lifted, the crew found themselves flying perilously close to the mountains, but made it safely back. His associates often said, "A Seaton calculation is carried out as if his life depended on it." After the War he was admitted to University College London (UCL) as an undergraduate. Thereafter, he spent all of his professional career at UCL. Seaton received his Batchelor's degree in 1948, and his Ph.D. in 1951. His tenure at UCL coincided with the golden age of atomic astrophysics, for he was largely responsible for it. Seaton was elected Fellow of the Royal Society in 1967, and as President of the Royal Astronomical Society (RAS) in 1978. He was the recipient of an Honorary Doctorate from the Observatoire de Paris, an Honorary D.Sc. from the Queen's University of Belfast, the Gold Medal for Astronomy by the RAS, the Guthrie Medal by the Institute of Physics, the Royal Society Hughes award for lifetime work by the RAS, and several other prestigious awards. Nevertheless, as Alex Dalgarno recently remarked, Seaton was not part of the establishment because he chose not to be. Though rooted in

    To report on the prevalence of lateral femoral cutaneous nerve (LFCN) palsy in patients who had undergone shoulder surgery in the beach chair position and to identify patient and surgical risk factors for its development. We retrospectively reviewed the medical records of 397 consecutive patients who underwent either open or arthroscopic shoulder surgery in the beach chair position by a single surgeon. Patient demographic and surgical data including age, gender, weight, body mass index (BMI), diabetes, procedure duration, and anesthesia type (general, regional, regional/general) were recorded. LFCN palsy symptoms were recorded prospectively at the initial postoperative visit and identified clinically by focal pain, numbness, and/or tingling over the anterolateral thigh. The median patient age was 59.0 years and consisted of 158 males (40%) and 239 (60%) females. Five cases of LFCN palsy were identified for a prevalence of 1.3%. These patients had a higher median weight (108.9 kg vs 80.7 kg, P = .005) and BMI (39.6 vs 29.4, P = .005) than the patients who did not develop LFCN palsy. Median age, gender, diabetes, and surgical time were not significantly different between the groups. All cases resolved completely within 6 months. LFCN palsy after shoulder surgery in the beach chair position in our study has a prevalence of 1.3%, making it an uncommon complication. Patients with elevated BMI should be counseled about its possible occurrence after shoulder surgery in the beach chair position. Level IV, prognostic.

    2016-09-27

    Prolonged sitting, such as when computing, has been linked to adolescent spinal pain. A chair should fit the user's body dimensions and aid the user in frequently changing sitting posture, rather than support one 'ideal' posture. Such a chair is not currently available to high school learners. To develop a novel experimental school chair. To determine whether the experimental chair encourages regular small range movement in all directions whilst students work at computers in class. To compare the number of postural changes between the normal static school chair and the experimental chair, whilst students do computing work. A development and validation study was conducted. Twelve high school students were randomly selected from a conveniently selected school. Fifteen minutes of 3D posture measurements were collected in both the prototype and school computer chair. The analysis focused on the frequency of postural movement. Data of eleven learners were analysed. There were statistically significant increases in the number of postural changes on the 'Experimental' chair compared to the school chair, for both pelvic side-flexion and pelvic rotation (ρ= 0.01). The experimental chair provided more postural movements when compared to the school computer chair. Future studies should use this experimental chair to determine the effect of increased postural movement, of especially the pelvis, on the prevalence and intensity of musculoskeletal symptoms of high school learners in the Cape Metropole area, Western Cape, South Africa.

    2008-03-01

    The present study aimed at determining the relationship of anthropometric dimensions of pupils from grades 1 to 8 in primary school with the dimensions of school chairs. Two dimensions of the chairs in daily use were evaluated to ascertain whether the fit is sufficient and the effect on pupils' sitting posture. The work included a sample of 556 pupils from three primary schools in Zagreb, Croatia and two types of furniture. Dimensions of school chairs were compared with three anthropometric variables of the pupils. Descriptive statistics were analysed for all variables. These study results have shown that furniture of appropriate dimensions is not available to a large number of students in Croatia. Currently supplied classroom equipment is provided in only two sizes and does not fit the users. It is recommended that task chairs may be acceptable if they are issued in four heights or individually adjustable chairs be introduced in Croatian schools. Furthermore it is strongly recommended that schools actively promote appropriate active sitting behaviour.

  16. Influence of Chair Vibrations on Indoor Sonic Boom Annoyance

    Rathsam, Jonathan; Klos, Jacob; Loubeau, Alexandra

    2015-01-01

    One goal of NASA’s Commercial Supersonic Technology Project is to identify candidate noise metrics suitable for regulating quiet sonic boom aircraft. A suitable metric must consider the short duration and pronounced low frequency content of sonic booms. For indoor listeners, rattle and creaking sounds and floor and chair vibrations may also be important. The current study examined the effect of such vibrations on the annoyance of test subjects seated indoors. The study involved two chairs exposed to nearly identical acoustic levels: one placed directly on the floor, and the other isolated from floor vibrations by pneumatic elastomeric mounts. All subjects experienced both chairs, sitting in one chair for the first half of the experiment and the other chair for the remaining half. Each half of the experiment consisted of 80 impulsive noises played at the exterior of the sonic boom simulator. When all annoyance ratings were analyzed together there appeared to be no difference in mean annoyance with isolation condition. When the apparent effect of transfer bias was removed, a subtle but measurable effect of vibration on annoyance was identified.

  17. Women chairs in academic medicine: engendering strategic intuition

    2017-01-01

    Purpose Because stereotypically masculine behaviors are required for effective leadership, examining female chairs’ leadership in academic medicine can provide insight into the complex ways in which gender impacts on their leadership practices. The paper aims to discuss this issue. Design/methodology/approach The author interviewed three female clinical chairs and compared the findings to interviews with 28 of their faculty. Grounded theory analysis of the subsequent text gathered comprehensive, systematic, and in-depth information about this case of interest at a US top-tier academic medical center. Findings Four of five themes from the faculty were consistent with the chair’s narrative with modifications: Prior Environment (Motivated by Excellence), Tough, Direct, Transparent (Developing Trust), Communal Actions (Creating Diversity of Opinion), and Building Power through Consensus (an “Artful Exercise”) with an additional theme, the Significance (and Insignificance) of a Female Chair. While faculty members were acutely aware of the chair’s gender, the chairs paradoxically vacillated between gender being a “non-issue” and noting that male chairs “don’t do laundry.” All three female chairs in this study independently and explicitly stated that gender was not a barrier, yet intuitively used successful strategies derived from the research literature. Originality/value This study suggests that while their gender was highlighted by faculty, these women dismissed gender as a “non-issue.” The duality of gender for these three female leaders was both minimized and subtly affirmed.

    Beach chair positioning during general anesthesia is associated with cerebral oxygen desaturation. Changes in cerebral oxygenation resulting from the interaction of inspired oxygen fraction (FIO2), end-tidal carbon dioxide (PETCO2), and anesthetic choice have not been fully evaluated in anesthetized patients in the beach chair position. This is a prospective interventional within-group study of patients undergoing shoulder surgery in the beach chair position that incorporated a randomized comparison between two anesthetics. Fifty-six patients were randomized to receive desflurane or total intravenous anesthesia with propofol. Following induction of anesthesia and positioning, FIO2 and minute ventilation were sequentially adjusted for all patients. Regional cerebral oxygenation (rSO2) was the primary outcome and was recorded at each of five set points. While maintaining FIO2 at 0.3 and PETCO2 at 30 mmHg, there was a decrease in rSO2 from 68% (SD, 12) to 61% (SD, 12) (P chair positioning. The combined interventions of increasing FIO2 to 1.0 and increasing PETCO2 to 45 mmHg resulted in a 14% point improvement in rSO2 to 75% (SD, 12) (P chair position. There was no significant interaction effect of the anesthetic at the study intervention points. Increasing FIO2 and PETCO2 resulted in a significant increase in rSO2 that overcomes desaturation in patients anesthetized in the beach chair position and that appears independent of anesthetic choice.

    2014-11-01

    Full Text Available Emeritus Professor A. J. “Tony” McMichael (1942–2014 was an internationally renowned and pioneering Australian academic and advocate in epidemiology, who was passionate about understanding the influences of the environment on human health. In an illustrious career spanning more than four decades, he made significant contributions to the scientific community and policy discourse—including ground-breaking research related to the health of children. McMichael was a prolific academic writer with over 300 peer-reviewed papers; 160 book chapters and two sole-authored books. However, his outstanding talent was for integrating complex and seemingly unrelated strands from the environmental and health sciences into a cohesive narrative—and highlighting its relevance to lay persons, scientists and governments alike. He was instrumental in validating this nascent field of research and inspiring many others to follow his lead.

    The goal of the present study is to characterize the black crust on the main stone used at Saint Michael's Church in Cluj-Napoca, Romania. The gases in the atmosphere, along with natural and artificial pollutants can cause damage the integrity of the stone when it comes in contact with the stone's chemistry. In order to explain the mechanism of stone decay due to black crust it is necessary to know what "weathering" means, so it must be seen as a complex process that consists of: type of material, the environment in which the material is located, and the amount of time required for the process to take place. Each material has particular properties, due to its composition and genesis. When it comes in contact with the acidity of the "acid rain" (caused by sulphur, nitrogen oxides and carbon dioxide), the rain penetrates into the pore structure, corroding it and "allowing" the atmospheric particles to penetrate the stone. St. Michael's Church is one of the oldest Gothic architectural monuments in Cluj, Romania, being built predominantly from Cenozoic (Upper Eocene) limestone, locally known as the Cluj Limestone. The main quarry was in Baciu, near Cluj. The samples that were collected from the Saint Michael's Church were characterized by means of: optical microscope, Scattering Electronic Microscope, thin sections, EDS The samples that were collected from the Saint Michael's Church went through a series of tests: optical microscope, Scattering Electronic Microscope, thin sections, EDX, and cross-section. The optical microscope analysis of the thin sections revealed that the black crust layer is approximately 0.01mm, and in the sample there are perfectly shaped ooides, which is characteristic to this type of limestone. The SEM analysis shows a resedimentation layer on the surface of the black crust, which occurred probably due to the effect of acid rain. Further information regarding the results of the test will be presented on the poster.

    2015-12-01

    Full Text Available The paper presents the results of studies and research aimed at identifying significant concepts of the design process dynamics of two European designers, Gió Ponti (Italy and Hans Wegner (Denmark. Two of their major chair designs, the Wishbone Chair (Wegner, 1944-49 and the Superleggera Chair (Ponti, 1951-57 were chosen as study cases. Their historical concept sources were carefully investigated and documented, since in the postwar years a tendency towards disregarding the dogmatic functionality of the interwar avant-garde furniture design occurred, making place for a different kind of innovation that did not contradict the natural evolution of form and function, but introduced an inherent elegance of form, as well as exceptional craftsmanship seen as adding value to the industrial production. Formal, compositional, structural and ergonomic elements were analysed, measurements of dimensions and angles were made and compared, sitting positions were visualised, in an attempt to unveil crucial aspects of specific design insights. The good understanding of the style connections, of the significant construction details that confirm the innovative, functional and well-balanced appearance of these chairs, of the careful selection of materials that characterised postwar austerity, contributed to an already confirmed investigative approach, which may be seen as a useful instrument of knowledge not only for design education, but also for design historians, furniture designers, manufacturers and artisans.

  11. The analytic setting today: using the couch or the chair?

    Science.gov (United States)

    Wiener, Jan

    2015-09-01

    This paper re-visits Murray Jackson's 1961 paper in the Journal of Analytical Psychology, 'Chair, couch and countertransference', with the aim of exploring the role of the couch for Jungian analysts in clinical practice today. Within the Society of Analytical Psychology (SAP) and some other London-based societies, there has been an evolution of practice from face-to-face sessions with the patient in the chair, as was Jung's preference, to a mode of practice where patients use the couch with the analyst sitting to the side rather than behind, as has been the tradition in psychoanalysis. Fordham was the founding member of the SAP and it was because of his liaison with psychoanalysis and psychoanalysts that this cultural shift came about. Using clinical examples, the author explores the couch/chair question in terms of her own practice and the internal setting as a structure in her mind. With reference to Bleger's (2013) paper 'Psychoanalysis of the psychoanalytic setting', the author discusses how the analytic setting, including use of the couch or the chair, can act as a silent container for the most primitive aspects of the patient's psyche which will only emerge in analysis when the setting changes or is breached. © 2015, The Society of Analytical Psychology.

    The importance of emotional intelligence (EI) in physicians has attracted attention as researchers begin to focus on the relationship of EI to retention, promotion, and productivity among academic physicians. However, to date, no formal evaluation of EI has been conducted among current department chairs. The objectives of this study were to assess the EI of current chairs of academic radiation oncology departments and to correlate EI with a self-reported assessment of burnout.The authors invited 95 chairs of academic radiation oncology departments to participate in a survey, approved by an institutional review board, consisting of the Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF) and the abbreviated Maslach Burnout Inventory (a-MBI). TEIQue-SF scores were evaluated for correlation with respondents' demographics and self-reported burnout scores on the a-MBI. Sixty chairs responded to the survey, for a response rate of 63.2%. The median (interquartile range) TEIQue-SF for the responding cohort was 172 (155-182) out of a maximum possible score of 210. The a-MBI emotional exhaustion and depersonalization subscores were low, with median (interquartile range) scores of 4 (2.25-6.75) and 1 (0-2.75) out of maximum possible scores of 18 and 30, respectively. Higher TEIQue-SF global scores were weakly correlated with decreased burnout. The study results show that academic radiation oncology chairs had a high EI and low rates of self-reported burnout. EI may be of increasing importance with respect to recruitment and retention of academic medical leaders.

    2018-01-01

    Exclusive breastfeeding is the responsibility of the mother after childbirth. A specific constraint arise for the mother when during the breastfeeding process, the place is not in accordance with the physiological condition of the mother's body. A not physiologically corrected lactation place will cause subjective disorders for breastfeeding mothers. Complaints that arise include quick tiredness, with certain muscles sore and pain, which will ultimately decrease the motivation of the mothers to perform exclusive breastfeeding especially in the first six months of the baby's birth. An improved ergonomic designed chair, this research used experimental method with group within treatment (treatment by subject) to solve the problem. The study took place in Maternity Clinic “CB” Badung regency, Bali. Subjective disorders are measured based on general fatigue and musculoskeletal disorders mothers breastfeeding. Fatigue is predicted using 30 items of questionnaires while musculoskeletal compaints are predicted from the Nordic Body Map questionnaire. Data were analyzed descriptively and inferentially in an experiment condition using using t-pair test. The results showed that there were significant differences in fatigue in general and skeletal musculoskeletal disorders between treatment 1 (using old chair) with treatment 2 (using repaired seats) in breastfeeding mothers. Fatigue in general decreased by 35.6% and skeletal musculoskeletal disorders decreased by 26.8%. It was concluded that improved breastfeeding mothers' seats may decrease subjective disorders during exclusive breastfeeding. It is therefore advisable for breastfeeding mothers to use seats that match their anthropometry.

    Dynamic chairs have the potential to facilitate movements that could counteract health problems associated with sedentary office work. This study aimed to evaluate whether a dynamic chair can increase movements during desk-based office work. Fifteen healthy subjects performed desk-based office work using a dynamic office chair and compared to three other conditions in a movement laboratory. In a field study, the dynamic office chair was studied during three working days using accelerometry. Equivocal results showed that the dynamic chair increased upper body and chair movements as compared to the conventional chair, but lesser movements were found compared to standing. No differences were found between the conditions in the field study. A dynamic chair may facilitate movements in static desk-based office tasks, but the results were not consistent for all outcome measures. Validation of measuring protocols for assessing movements during desk-based office work is warranted. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Although the safety of the beach-chair position (BCP) is widely accepted, rare devastating neurologic complications have been reported and attributed to cerebral hypoperfusion. Cerebral oxygenation (regional oxygen saturation [rSO 2 ]) can be monitored noninvasively using near-infrared spectroscopy. The purpose of this study was to determine the effect of BCP angle on cerebral oxygenation in patients undergoing shoulder surgery in the BCP. Fifty patients undergoing shoulder arthroscopy were prospectively enrolled to participate. Following induction of general anesthesia, each patient's rSO 2 was recorded at 0° of elevation and again at 30°, 45°, 60°, and 80° of elevation. Mean rSO 2 values and mean differences in rSO 2 were reported. An average total decrease of 5% in rSO 2 was seen when comparing 0° with 80° (P chair angles of 0° versus 30° (P chair angle, leading to a linear decline in rSO 2 as the BCP increased (regression slope of -0.060%/°, P <.001). No patient's cerebral oxygenation dropped greater than 20% from baseline. Neither body mass index nor American Society of Anesthesiologists score had a significant impact on the relation of rSO 2 to BCP angle. The average drop in rSO 2 is significantly less than the threshold of 20% used as an identifier for a cerebral deoxygenation event. This study illustrates the direct effect the BCP angle has on cerebral oxygenation. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

    2015-06-01

    Procedural sedation and analgesia (PSA) is often required to perform dental procedures in children. Serious adverse outcomes, while rare, are usually preventable. To determine the proportion of dental practitioners making use of paediatric dental chair PSA in Gauteng Province, South Africa, describe their PSA practice, and determine compliance with recommended safety standards. A prospective, contextual, descriptive study design was used, with 222 randomly selected dental practitioners contacted to determine whether they offered paediatric dental chair PSA. Practitioners offering PSA were then asked to complete a web-based questionnaire assessing their practice. Of the 213 dental practitioners contacted, 94 (44.1%; 95% confidence interval 37 - 51) provided PSA to children. Most patients were 1 - 5 years old, although there were practices that offered PSA to infants. While most procedures were performed under minimal to moderate sedation, deep sedation and general anaesthesia were also administered in dental rooms. Midazolam was the most frequently used sedative agent, often in conjunction with inhaled nitrous oxide; 28.1% of PSA providers administered a combination of three or more agents. Presedation patient assessment was documented in 83.0% of cases, and informed consent for sedation was obtained in 75.6%. The survey raised several areas of concern regarding patient safety: 41.3% of dental practices did not use any monitoring equipment during sedation; the operator was responsible for the sedation and monitoring of the patient in 41.3%; 43.2% did not keep any recommended emergency drugs; and 19.6% did not have any emergency or resuscitation equipment available. Most respondents (81.8%) indicated an interest in sedation training. Paediatric dental chair PSA was offered by 44.1% of dental practitioners interviewed in Gauteng. Modalities of PSA provided varied between practices, with a number of safety concerns being raised.

    Michael Faraday (1791-1867) was one of the most important men of science in nineteenth century Britain. His discoveries of electro-magnetic rotations (1821) and electro-magnetic induction (1831) laid the foundations of the modern electrical industry. His discovery of the magneto-optical effect and diamagnetism (1845) led him to formulate the field theory of electro-magnetism, which forms one of the cornerstones of modern physics.These and a whole host of other fundamental discoveries in physics and chemistry, together with his lecturing at the Royal Institution, his work for the state (includi

    Full Text Available Asked to pick a single representative ‘German’ piece for a discourse on ‘Law and Literature’ one almost inevitably ends up with Kleist’s tale Michael Kohlhaas. It seems to be the literary incarnation of the German stance vis-à-vis the law. It is all about horses; it could just as well be about dogs. Kohlhaas fights a devastating battle, using legal means and outright violence, even warfare, for their recovery in good shape. Victorious eventually with his legal actions, he is happy to trade in his own life for this victory, thus giving an extreme example for the nice line between being in the right and pursuing this position with disproportionate rigour. Of course, the interpretations of Michael Kohlhaas (which, in its complete version, dates of 1810 have varied from epoch to epoch as well as from reader to reader. It is not possible to rehearse the bulk of ‘Kohlhaas literature’. In comparing legal cultures, it might be of interest to look into the question why such a somber story on the law forms part and will continue to form part of the German cultural heritage. Si se tiene que elegir un único representante “alemán” para una ponencia sobre “derecho y literatura”, es inevitable optar por la obra de Kleist, Michael Kohlhaas. Parece la encarnación literaria de la posición alemana hacia el derecho. El libro trata de caballos; también podría tratar sobre perros. Kohlhaas libra una batalla devastadora usando medios legales y la violencia pura y dura, incluso la guerra, para que se recuperen en buena forma. Finalmente resulta ganador mediante acciones legales, está contento de dedicar su propia vida para conseguir esta victoria, dando así un ejemplo extremo de la línea que existe entre tener la razón y seguir esta posición con un rigor desproporcionado. Por supuesto, las interpretaciones de Michael Kohlhaas (publicado en 1810 han variado de una época a otra, y de un lector a otro. No es posible revisar el grueso de

  13. Bourdieu, Department Chairs and the Reform of Science Education

    Science.gov (United States)

    Melville, Wayne; Hardy, Ian; Bartley, Anthony

    2011-11-01

    Using the insights of the French sociologist, Pierre Bourdieu, this article considers the role of the science department chair in the reform of school science education. Using Bourdieu's 'thinking tools' of 'field', 'habitus' and 'capital', we case study the work of two teachers who both actively pursue the teaching and learning of science as inquiry. One teacher, Dan, has been a department chair since 2000, and has actively encouraged his department to embrace science as inquiry. The other teacher, Leslie, worked for one year in Dan's department before being transferred to another school where science teaching continues to be more traditional. Our work suggests that there are three crucial considerations for chairs seeking to lead the reform of science teaching within their department. The first of these is the development of a reform-minded habitus, as this appears to be foundational to the capital that can be expended in the leadership of reform. The second is an understanding of how to wield power and position in the promotion of reform. The third is the capacity to operate simultaneously and strategically within, and across, two fields; the departmental field and the larger science education field. This involves downplaying administrative logics, and foregrounding more inquiry-focused logics as a vehicle to challenge traditional science-teaching dispositions-the latter being typically dominated by concerns about curriculum 'coverage'.

    A rotation chair test has been used to evaluate the function of the horizontal semicircular canals. Currently, two chair systems according to the presence of cylindrical darkroom are used in a clinic setting. However, it has not been thoroughly investigated whether one system is superior to the other system or not. In this study, we aimed to compare test outcomes and subject convenience between two systems. Twenty subjects with no history of otologic disease were enrolled. Subjects were tested with two systems: system [A] with a cylindrical chamber and system [B] with no chamber. The results of sinusoidal harmonic acceleration (SHA), step velocity (SV), and visual fixation (VFX) tests were compared between the systems. Subject convenience was assessed with a questionnaire survey and results were compared between the systems. There were no significant differences in gain or asymmetry in SHA test between the systems. However, the phase of system [A] was significantly lower than that of system [B] at 0.16 Hz. There was no significant difference between the systems in directional preponderance (DP) gain or DP time constant. Regarding the VFX test, gain was higher in system [A] than system [B]. Subjects reported less stuffiness and less anxiety with system [B] than system [A], while preferring the system [A] goggles. A rotation chair system without a darkroom can provide a more comfortable experience for subjects in terms of stuffiness and anxiety, while showing comparable results in SHA and SV tests with a darkroom system.

    Family medicine faces significant challenges and opportunities in the next 20 years. This study was conducted to determine the importance of departmental factors to the discipline as perceived by the departmental chairs. Following brainstorming of 139 potential important factors, items were grouped into 81 clusters. All 120 family medicine departmental chairs were surveyed as to the importance of each to the discipline. The 81 items were empirically grouped into 9 areas and differences in rankings were analyzed using Friedman's Test. Fifty-eight (48%) of the chairs responded. Although 35 (43%) of the items received a mean rating of 4.0 or higher, teaching and patient care items were among the highest rated. Research and fellowship items were among those receiving the poorest ratings. Of the 9 areas, teaching and faculty issues were ranked significantly higher and fellowships ranked significantly lower than other areas (F = 183.5, p important, teaching and faculty issues were ranked as the most important areas to the discipline while fellowships was ranked least important.

    Thiol-Michael "click" reactions are essential synthetic tools in the preparation of various materials including polymers, dendrimers, and other macromolecules. Despite increasing efforts to apply thiol-Michael chemistry in a controlled fashion, the selectivity of base- or nucleophile-promoted thiol-Michael reactions in complex mixtures of multiple thiols and/or acceptors remains largely unknown. Herein, we report a thorough fundamental study of the selectivity of thiol-Michael reactions through a series of 270 ternary reactions using 1 H NMR spectroscopy to quantify product selectivity. The varying influences of different catalysts/initiators are explored using ternary reactions between two Michael acceptors and a single thiol or between a single Michael acceptor and two thiols using three different catalysts/initiators (triethylamine, DBU, and dimethylphenylphosphine) in chloroform. The results from the ternary reactions provide a platform from which sequential quaternary, one-pot quaternary, and sequential senary thiol-Michael reactions were designed and their selectivities quantified. These results provide insights into the design of selective thiol-Michael reactions that can be used for the synthesis and functionalization of multicomponent polymers and further informs how catalyst/initiator choice influences the reactivity between a given thiol and Michael acceptor.

    Beach chair positioning during general anesthesia is associated with a high incidence of cerebral desaturation; poor neurological outcome is a growing concern. There are no published data pertaining to changes in cerebral oxygenation seen with increases in the inspired oxygen fraction or end-tidal carbon dioxide in patients anesthetized in the beach chair position. Furthermore, the effect anesthetic agents have has not been thoroughly investigated in this context. We plan to test the hypothesis that changes in inspired oxygen fraction or end-tidal carbon dioxide correlate to a significant change in regional cerebral oxygenation in anesthetized patients in beach chair position. We will also compare the effects that inhaled and intravenous anesthetics have on this process. This is a prospective within-group study of patients undergoing shoulder arthroscopy in the beach chair position which incorporates a randomized comparison between two anesthetics, approved by the Institutional Review Board of the University of Michigan, Ann Arbor. The primary outcome measure is the change in regional cerebral oxygenation due to sequential changes in oxygenation and ventilation. A sample size of 48 will have greater than 80% power to detect an absolute 4-5% difference in regional cerebral oxygenation caused by changes in ventilation strategy. The secondary outcome is the effect of anesthetic choice on cerebral desaturation in the beach chair position or response to changes in ventilation strategy. Fifty-four patients will be recruited, allowing for drop out, targeting 24 patients in each group randomized to an anesthetic. Regional cerebral oxygenation will be measured using the INVOS 5100C monitor (Covidien, Boulder, CO). Following induction of anesthesia, intubation and positioning, inspired oxygen fraction and minute ventilation will be sequentially adjusted. At each set point, regional cerebral oxygenation will be recorded and venous blood gas analysis performed. The overall

    The aim of this study was to investigate the effect of five chair designs on interface pressure distribution and tissue perfusion in the buttock-thigh region. Prolonged sitting has been found to contribute to the symptoms of work-related low back pain. Studies have found that chair design affects users' sitting posture and comfort. As sitting applies pressure to the user, it is necessary to investigate how chair design affects sitting pressure and tissue perfusion during sitting. We tested five chair designs (Suspension A, Suspension B, Foam A, Foam B, and bicompliant) on 15 young, healthy females. Sitting interface pressure and buttock-thigh tissue perfusion (in terms oftranscutaneous partial pressure of oxygen and carbon dioxide, tcPO2 and tcPCO2, respectively) were measured during 10-min sitting on each chair. We found that chair design significantly affected the distribution of the sitting pressure (p chair designs, the anterior portion of the seat sustained the lowest contact pressure. It was also found that tcPO2 was the lowest (p chair designs. Chair design and materials of the seat significantly affect the sitting interface pressure distribution and tissue perfusion in sitting area. Further evaluation of these outcomes may provide useful information to correlate chair design with sitting comfort.

    2012-03-01

    Full Text Available Michael Longley’s father has been a recurring presence in the poet’s work from his earliest to his most recent collection. This paper examines the exceptional strength of that bond reflected in the varied and changing ways in which the poet has responded to it – memorizing and mourning his loss; discovering through his father’s First World War stories a means of memorialising loss of life in contemporary conflicts and a way of facing the history of the twentieth century; confronting his own ageing and sense of mortality; and marking the specific, but also representative, generational history of his family. Close readings of key poems are offered to highlight Longley’s skills in meeting his own exacting standards of aesthetic propriety and moral and social responsibility for writers of elegy in order to avoid either exploitation of tragedy and loss, or facile gestures of consolation.

    Full Text Available This project aims at providing a detailed analysis of the major features of the theory of postmodern narrative and at going through the novel The Hours by the American writer Michael Cunningham concentrating on some postmodern narrative techniques. To do so, the researcher goes through the theories set forth by some postmodern theoreticians like Roland Barthes, Jacque Derrida, Jean-François Lyotard and Julia Kristeva to investigate the postmodern narrative techniques and elements used in the novel. The researcher first examines the theories and then critically applies them on the novel. The article goes through the most eminent elements of postmodern narrative including intertextuality, stream of consciousness style, fragmentation and representation respectively which are delicately utilized in The Hours. The article concludes by recommending a few directions for the further research.

    Although there is clinical and historical evidence for a vivid relation between the vestibular and emotional systems, the neuroscientific underpinnings are poorly understood. The “spin doctors” of the nineteenth century used spinning chairs (e.g., Cox’s chair) to treat conditions of mania or elevated arousal. On the basis of a recent study on a hexapod motion-simulator, in this prototypic investigation we explore the impact of yaw stimulation on a spinning chair on mood states. Using a controlled experimental stimulation paradigm on a unique 3-D-turntable at the University of Zurich we included 11 healthy subjects and assessed parameters of mood states and autonomic nervous system activity. The Multidimensional Mood State Questionnaire and Visual Analog Scales (VAS) were used to assess changes of mood in response to a 100 s yaw stimulation. In addition heart rate was continuously monitored during the experiment. Subjects indicated feeling less “good,” “relaxed,” “comfortable,” and “calm” and reported an increased alertness after vestibular stimulation. However, there were no objective adverse effects of the stimulation. Accordingly, heart rate did not significantly differ in response to the stimulation. This is the first study in a highly controlled setting using the historical approach of stimulating the vestibular system to impact mood states. It demonstrates a specific interaction between the vestibular system and mood states and thereby supports recent experimental findings with a different stimulation technique. These results may inspire future research on the clinical potential of this method. PMID:24133463

    The design and synthesis of biomass-derived triazoles and the in vitro evaluation as potential anticancer agents are described. The discovery of base-catalyzed retro-aza-Michael//aza-Michael isomerizations allowed the exploration of the chemical space by affording novel types of triazoles, difficult to obtain otherwise. Following this strategy, 2,4-disubstituted 1,2,3-triazoles could be efficiently obtained from the corresponding 1,4-disubstituted analogues.

    The sitting beach-chair position is regularly used for shoulder surgery and anesthesia may be induced in that position. We tested the hypothesis that the cardiovascular challenge induced by induction of anesthesia is attenuated if the patient is placed in a reclining beach-chair position....... Anesthesia was induced with propofol in the sitting beach-chair (n = 15) or with the beach-chair tilted backwards to a reclining beach-chair position (n = 15).

    Regardless of the constantly increasing time man is spending in a sitting position, there is still a lack of objective chair quality assessment criteria. The aim of this paper is to find the answer to whether respiratory chest movement measurements can be a chair quality indicator. The study included 34 participants (mean 34.7 years±5.2). Their chest movements were assessed using respiratory inductive plethysmography while sitting on two subsequent chairs. Significant differences in chest movements depending on chair type were observed concerning the breathing duct (upper and lower) and breathing movement amplitude. The amplitude of the upper respiratory track in the first chair was higher (239.4 mV) compared with the second seat (207.3 mV) (p=.018). The analyzed parameters of respiratory chest movement may become a helpful indicator for design and selection of chairs which enable people to both work and relax in the most ergonomic conditions.

  7. Development of New Wheel-Chair for Sports Competition

    Full Text Available The purpose of this study was to develop the new wheel-chair which had the function to drive straight by one-hand operation. To perform this purpose, the driving force transmission axis (DFTA which had transmitted the driving force from the one side of wheel to another side of that was developed. The wheel-chair could drive straight by one-hand operation by the DFTA. The large torque, however, was generated in the DFTA, because the DFTA transmitted the driving force from the one side of wheel to another side by the axis of small diameter. Furthermore, the shear stress in the DFTA generated by this torque would lead to the DFTA break. The shear stress in the DFTA was calculated to examine the axial strength and durability. On the DETA of the wheelchair, the maximum shear stress calculated from the torque in driving was 39.53 MP and this was defined as the standard of the demand specifications as a strength and durability of the DFTA.

    Strong evidence exists associating job satisfaction and risk of burnout with productivity, efficiency, and creativity in many organizations. However no data are available assessing chairs of surgery. This study assessed job satisfaction and risk for burnout of surgical chairs from Europe and North America and identified contributing factors. A survey among 650 chairs in surgery from 23 European and 2 North American countries was conducted in 2012. Satisfaction at work was analyzed using the validated Global Job Satisfaction (GJS) instrument and the abbreviated Maslach Burnout Inventory. Additional items targeting personal and environmental factors were included. The rate of chairs reached successfully was 86%, the overall response rate was 29% (188/650), with 1% female. Median age was 58 years. 11% of chairs were dissatisfied with work. Younger age and being fewer years in practice as a chair was associated with higher job satisfaction (P = .054 and P = .003). Surgical specialty with the greatest median GJS score was hepatopancreatobiliary, whereas vascular surgery scored lowest. Chairs desire to devote 20% more of their time on research. Clerical support as well as the ability to be innovative was suggested by 51% and 45%, respectively, to improve job satisfaction. Compared with Europeans, North American chairs were overall more satisfied and would recommend their job to their children. North American chairs seem to be more satisfied at work and at less risk for burnout than European chairs. The overall job satisfaction was greater among chairs compared with previously published reports of young, board-certified surgeons or residents (89% vs 87% and 66%, respectively). The superior satisfaction in chairs is strongest related to career achievements, innovation, and lifestyle. Copyright © 2014 Elsevier Inc. All rights reserved.

    2007-03-01

    The popularity of the gym ball has led to its increased use in programs designed for fitness, rehabilitation and prevention. Some people are using the gym ball to replace the office chair and others are sitting on it at home, which has created some controversy among therapists, researchers, ergonomics experts and the general public. The controversy is due in part to a lack of knowledge and experience with this application for the gym ball. Both patients in this report were suffering with low back pain, and both improved when they began consistently using the gym ball. There are two reasons for case presentations, to document a treatment of a condition and to promote discussion that may lead to research. This presentation will hopefully accomplish this.

    Academic health centers (AHCs) are under unprecedented pressure, making strong leadership during these challenging times critical. Department chairs have tremendous influence in their AHCs, yet data indicate that--despite outstanding academic credentials--they are often underprepared to take on these important leadership roles. The authors sought to improve the approach to recruiting, developing, and giving feedback to department chairs at their institution, the Indiana University School of Medicine (IUSM), by reorganizing these processes around six key leadership competencies: leadership and team development, performance and talent management, vision and strategic planning, emotional intelligence, communication skills, and commitment to the tripartite mission. Over a two-year period (2009-2011), IUSM faculty and administrators developed standardized recruitment procedures to assess potential chairs based on the six leadership domains, and searches are now streamlined through centralized staff support in the dean's office. Additionally, IUSM offers a chair development series to support learning around these leadership competencies and to meet the stated professional development needs of the chairs. Finally, chairs receive structured feedback regarding their leadership (among other considerations) through two different assessment instruments, IUSM's Department Chair 360° Leadership Survey and IUSM's Faculty Vitality Survey--both of which the dean reviews annually. Strategically attending to the way that chairs are selected, developed, and given feedback has tremendous potential to increase the success of chairs and, in turn, to constructively shape the culture of AHCs.

    Comments on the original article, "Influence of stressors on breast cancer incidence in the Women's Health Initiative" by Y. L. Michael et al (see record 2009-03297-001). The current authors assert that Michael et al (2009) missed an opportunity for a straightforward reporting of null findings concerning the association between stress and incidence of cancer. They urge greater skepticism toward the claims about a stress-cancer link more generally. Using data from the Women's Health Initiative, Michael and colleagues suggested an association between stress and the incidence of breast cancer. However, the current authors believe their results and those from other studies failed to confirm that stress is a risk factor of breast cancer. Starting with their abstract and continuing in their discussion, Michael et al selectively and inaccurately reported findings with a strong confirmatory bias, and with further selective and uncritical reference to the existing literature. Moreover, they inadvertently perpetuated the direct and indirect influence of discredited data in the literature purporting to show a stress-cancer link. (c) 2011 APA, all rights reserved.

    measurements. App accelerometer data during the 30-second Chair Stand Test (PCC=.890) and gravity sensor data during the Stair Climb Test (PCC=.865) were highly correlated to gold-standard manual measurements. Greater than 95% of values on Bland-Altman plots comparing the manual data to the app data fell within the 95% limits of agreement. Strong intraclass correlation was found for trials of the 30-second Chair Stand Test (ICC=.968) and Stair Climb Test (ICC=.902). Standard errors of measurement for both tests were found to be within acceptable thresholds for MATLAB. Repeatability coefficients for the 30-second Chair Stand Test and Stair Climb Test were 0.629 and 1.20, respectively. App-based performance testing of the 30-second Chair Stand Test and Stair Climb Test is valid and reliable, suggesting its applicability to future, larger-scale studies in the osteoarthritis patient population. ©Gautam Adusumilli, Solomon Eben Joseph, Michael A Samaan, Brooke Schultz, Tijana Popovic, Richard B Souza, Sharmila Majumdar.

    Specifically designed restraint chairs are the preferred method of restraint for research studies that require NHP to sit in place for sustained periods of time. In light of increasing emphasis on refinement of restraint to improve animal wellbeing, it is important to have a better understanding of this potentially stressful procedure. Although chair restraint is used internationally, very little published information is available on this subject. We developed a survey to obtain an overview of equipment, procedures, and plans for improvement regarding chair restraint. We received 101 responses from people working in academic, government, contract research, and pharmaceutical laboratories within the Americas, Europe and Asia. Findings indicate that the majority of laboratories using restraint chairs work with macaque species. Restraint chairs are used for a wide range of procedures, including cognitive testing, recording neuronal activity, functional MRI, intravenous infusion, and blood sampling. Approximately 2/3 of laboratories use an enclosed 'box chair,' which the animal is trained to enter and then to extend its head through an opening on the top of the chair; the remaining one third of laboratories use an 'open chair' design, in which manual handling or the pole-and-collar system is used to transfer and secure the animal into the chair. Respondents reported that when selecting the type of chair to use, they considered comfort for the animal, ease of use, and the ability to adjust fit between animals of different sizes. Various training methods and timeframes are used to prepare macaques for restraint chair procedures. Several laboratories are incorporating greater use of positive reinforcement training. The community that uses these restraint procedures needs to work together to define best practice; our survey results can help in that effort.

    Full Text Available El antropólogo Michael Taussig ha producido una gran cantidad de trabajo etnográfico sobre América Latina en el que toma por objeto la universalidad de la cultura burguesa y en el que, al reorientar la mirada del etnógrafo hacia los elementos embriagantes y orgiásticos de la vida, atenúa las líneas que dividen ciencia y arte. En este ensayo tengo la intención de mostrar lo siguiente: 1 que sus etnografías sobre magia, violencia y el Es-tado, están enraizadas en su priorización del mundo fenomenológico y en una concepción materialista en deuda con la teoría estética alemana del si-glo XIX y con la antropología especulativa de Karl Marx y Walter Benjamin; 2 que su proyecto etnográfico no consiste en la eliminación de la ciencia del ámbito de la etnografía, sino en disminuir el papel de la explicación en favor de una forma de escritura que, como el arte, trabaja para refundar las imágenes del mundo.

    Full Text Available The Dublin-born musician, Michael W. Balfe, was a singer, composerand conductor whose brilliant musical career was heavily influenced byformative experiences in Italy. In 1825, Balfe, interested in broadeninghis musical studies first went to Paris where he was introduced to thegreat composers, Luigi Cherubini and Gioachino Rossini, who took apersonal interest in him and his musical talents. On the advice of Rossinihe spent the next few years in Italy studying singing with the famousRossini singer, Filippo Galli, and taking music composition lessonsfrom Ferdinando Paer, in Rome. Later in Milan he studied harmonyand counterpoint with Vincenzo Federici. By 1831, when he was only23 years old, his first three operas had been produced in Palermo, Pavia,and Milan. He returned to London in August 1835, participatingwith the great Lablache, Tamburini, Rubini and Grisi in a concert inVauxhall Gardens. In 1834 he made his debut at La Scala, Milan, singingopposite the renowned mezzo-soprano, Maria Malibran in Rossini’sOtello. He appeared again with Malibran in Venice early in 1835,singing once more in Rossini and Bellini operas. Balfe worked as a singerand composer throughout the Italian peninsula/states during the years,1825-1835 and this article will chart these experiences and demonstratehow the time he spent in Italy and the people he met, influenced hislife and later career as an important and popular European composer.

    Full Text Available The 1912 poem "A Dance of Death" by Michael Field (pen name of Katherine Bradley and her niece Edith Cooper depicts Salome in an alternate version of the biblical story: this Salome dances on a frozen river, falls through the ice, and is decapitated on a jagged edge. Nonetheless, her beautiful head continues dancing over the frozen river. This poem is highly unusual, especially in the context of the other poems in the postconversion volume Poems of Adoration, because it questions, rather than submits to, authority. In re-writing a familiar Christian tale, as well as a familiar decadent theme, Field uses the poem to assert the supremacy of their artistic vision, which (despite their ardent Catholicism cannot be subject to any law outside themselves. Like the continually dancing head of Salome, which continues to create beauty even after nature (and perhaps God has struck it down, the poet is subjugate only to her own law and creates without boundaries or restrictions on her art. Bradley and Cooper were acutely aware of their authorial persona (actively taking not only a masculine but also a singular poetic identity, and their mode of reconciling the apparent contradictions of this identity are mirrored in their presentation of Salome in a "Dance of Death."

    Air passenger miles will likely double by year 2020. The altered and restrictive environment in an airliner cabin can influence hematological homeostasis in passengers and crew. Flight-related deep various thromboemboli (DVT) have been associated with at least 577 deaths on 42 of 120 airlines from 1977 to 1984 (25 deaths/million departures), whereas many such cases go unreported. However, there are four major factors that could influence formation of possible flight-induced DVT: sleeping accomodations (via sitting immobilization), travelers' medical history (via tissue injury), cabin environmental factors (via lower partial pressure of oxygen and lower relative humidity), and the more encompassing chair-rest deconditioning (C-RD) syndrome. There is ample evidence that recent injury and surgery (especially in deconditioned hospitalized patients) facilitate thrombophlebitis and formation of DVT that may be exacerbated by the immobilization of prolonged air travel. In the healthy flying population immobilization factors associated with prolonged (> 5 hr) C-RID such as total body dehydration, hypovolemia and increased blood viscosity, and reduced various blood flow (pooling) in the legs may facilitate formation of DVT. However, data from at least four case-controlled epidemiological studies did not confirm a direct causative relationship between air travel and DART, but factors such as history of vascular thromboemboli, various insufficiency, chronic heart failure, obesity, immobile standing position, more than 3 pregnancies, infectious disease, long-distance travel, muscular trauma and violent physical effort were significantly more frequent in DVT patients than in controls. Thus, there is no clear, direct evidence yet that prolonged sitting in airliner seats, or prolonged experimental chair-rest- or bed- rest-deconditioning treatments cause deep various thromboemboli in healthy people.

    Air passenger miles will likely double by year 2020. The altered and restrictive environment in an airliner cabin can influence haematological homeostasis in passengers and crew. Flight-related deep venous thromboemboli (DVT) have been associated with at least 577 deaths on 42 of 120 airlines from 1977 to 1984 (25 deaths/million departures), whereas many such cases go unreported. However, there are four major factors that could influence formation of possible flight-induced DVT: sleeping accommodations (via sitting immobilisation); travellers' medical history (via tissue injury); cabin environmental factors (via lower partial pressure of oxygen and lower relative humidity); and the more encompassing chair-rest deconditioning (C-RD) syndrome. There is ample evidence that recent injury and surgery (especially in deconditioned hospitalised patients) facilitate thrombophlebitis and formation of DVT that may be exacerbated by the immobilisation of prolonged air travel.In the healthy flying population, immobilisation factors associated with prolonged (>5 hours) C-RD such as total body dehydration, hypovolaemia and increased blood viscosity, and reduced venous blood flow (pooling) in the legs may facilitate formation of DVT. However, data from at least four case-controlled epidemiological studies did not confirm a direct causative relationship between air travel and DVT, but factors such as a history of vascular thromboemboli, venous insufficiency, chronic heart failure, obesity, immobile standing position, more than three pregnancies, infectious disease, long-distance travel, muscular trauma and violent physical effort were significantly more frequent in DVT patients than in controls.

    Full Text Available The majority of female batik workers uses non-ergonomic chairs (dingklik that pose risks of musculoskeletal disorders. This study aimed to design an ergonomic chair and evaluate its effectiveness in reducing musculoskeletal disorders among the workers. This is a quasi-experimental study (using one group pre and post-test design on 50 female batik workers selected by quota sampling. Musculoskeletal disorders were measured among the samples before and after the use of the designed ergonomic chair which they were asked to use for two months. T-test, ANCOVA, Wilcoxon test, McNemar test and Chi Square test were used for the analysis. The study found statistical significant differences of risk factor against musculoskeletal disorders among the workers before and after their use of the designed ergonomic chair (p=0.000; and of musculoskeletal disorders before and after using the ergonomic chair (p= 0,035. Body Mass Index (BMI was identified as a confounding factor, and statistical significant difference of musculoskeletal disorders were also found among the workers with 25 BMI even before and after using the ergonomic chair (p=0.033 and p=0.015 respectively. By ANCOVA statistical test, after controlling BMI, another statistical difference of musculoskeletal disorders was also identified before and after using the ergonomic chair (p=0.033. It is concluded that the designed ergonomic chair is effective to reduce the risk of musculoskeletal disorders.

    2014-01-01

    The sitting beach-chair position is regularly used for shoulder surgery and anesthesia may be induced in that position. We tested the hypothesis that the cardiovascular challenge induced by induction of anesthesia is attenuated if the patient is placed in a reclining beach-chair position. Anesthesia was induced with propofol in the sitting beach-chair (n = 15) or with the beach-chair tilted backwards to a reclining beach-chair position (n = 15). The last group was stepwise tilted to the sitting beach-chair position prior to surgery. Hypotension was treated with ephedrine. Continuous hemodynamic variables were recorded by photoplethysmography and frontal cerebral oxygenation (ScO2) by near infrared spectroscopy. Significant differences were only observed immediately after the induction when patients induced in a reclining beach-chair position had higher mean arterial pressure (MAP) (35 ± 12 vs. 45 ± 15 % reduction from baseline, p = 0.04) and ScO2 (7 ± 6 vs. 1 ± 8% increase from baseline, p = 0.02) and received less ephedrine (mean: 4 vs. 13 mg, p = 0.048). The higher blood pressure and lower need of vasopressor following induction of anesthesia in the reclining compared to the sitting beach-chair position indicate more stable hemodynamics with the clinical implication that anesthesia should not be induced with the patient in the sitting position.

    Keith, Samuel J; Buckley, Peter F

    2011-01-01

    Effective leadership in academic medicine requires a broad constellation of skills, experiences, and core values. The authors sought to describe and define these. The authors conducted a web-based survey among 132 Chairs of North American departments of psychiatry. Eighty-five Chairs (64%) responded to the survey, the majority of whom were first-time Chairs. Identified leadership attributes included strategic/visionary acumen, interpersonal communication skills, core administrative and academic/technical skills, motivational capacity, personal integrity, and altruism/tenacity. The identified values are consistent with the leadership attributes that are described as necessary for success in the business community. Developing the required skill-set among faculty who aspire to become a departmental Chair is an important commitment for Deans and extant psychiatry Chairs. Copyright © 2011 Academic Psychiatry

    Pharmacokinetic modelling of radiotracers for positron emission tomography (PET) imaging of neuroreceptors can be performed with time-activity data for brain and blood. We aimed to develop an alternative to withdrawal of arterial blood samples for acquisition of a blood curve. A supportive primate chair was constructed out of styrofoam and fixed to the head portion of the bed of a PET scanner. A lightly anaesthetised rhesus monkey was positioned in the chair in a sitting position and injected with the radiotracer. The styrofoam chair provided sufficient support for the monkey. The presence of the chair in the PET scanner caused negligible attenuation of radiation, allowing simultaneous acquisition of dynamic data from the subject's brain and heart. We conclude that a styrofoam primate chair is an ideal tool to measure blood and brain data from a rhesus monkey with PET. Invasiveness to the animal is reduced, as well as experimenter time.

    Determining gait speed as a measure of physical performance is recommended in diagnosing sarcopenia. Gait speed measurements require a certain amount of space (e.g. a 6-m course), and might not be feasible in clinical settings or heath checkup examination sites. We developed a formula to estimate chair stand time based on gait speed, and examined the validity (sensitivity and specificity) of using the estimated chair stand time cut-off point as a surrogate for the recommended gait speed cut-off point. Chair stand time was defined as the time it took to stand up from a standard chair five times. Gait speed was calculated from the time required for participants to walk a 6-m course at their usual pace. Simple regression analysis showed a significant negative relationship between chair stand time and gait speed (P chair stand time = -8.41 × gait speed + 20.0 (R 2  = 0.34). Therefore, the chair stand time cut-off point was estimated to be 13.3 s by inserting the recommended gait speed cut-off of 0.8 m/s in the above formula. Rounding off to make its use simpler, the estimated chair stand time cut-off was 13 s. The sensitivity and specificity of the estimated chair stand time cut off were 0.75 and 0.94, respectively. Chair stand time might be useful as a surrogate of gait speed when screening for sarcopenia. Geriatr Gerontol Int 2017; 17: 659-661. © 2016 Japan Geriatrics Society.

    2002-04-01

    The purpose of this study was to determine the prevalence of burnout in chairs of academic departments of obstetrics and gynecology, identify important stressors, and develop strategies to treat and prevent burnout. We performed a cross-sectional study of 131 chairs in the United States and Puerto Rico. We used a 6-part questionnaire focusing on demographics, potential stressors, satisfaction with personal and professional life, self-efficacy, burnout as measured by the Maslach Burnout Inventory-Human Services Survey (MBI-HSS), and support from the spouse/partner and family. Statistical analyses were performed with the chi(2) test for categorical variables and t test or analysis of variance for continuous variables. Questionnaires were returned from 119 chairs, 110 men and 9 women, a response rate of 91%. Chairs had served an average of 7.2 years. They worked an average of 67.4 hours each week, spending 45% of their time in administrative duties, 31% in patient care, 15% in teaching, and 8% in research. Female chairs worked significantly more hours per week than male chairs, 76.9 versus 66.7 hours (P =.005). Chairs who had served >10 years worked significantly fewer hours each week than did those who had been chairs budget deficits, Medicare/Medicaid billing audits, loss of key faculty, union disputes, and faculty, resident, and staff dismissals. To deal with stress, chairs most often spent time with family and friends. Twenty-two percent of chairs were somewhat-very dissatisfied with their positions. The MBI-HSS revealed a high subscale score for emotional exhaustion, moderate-high for depersonalization, and high for personal accomplishment. High emotional exhaustion was observed in younger chairs, those who worked nearly 70 hours each week, and those with less spouse/partner support. Burnout was more common in new chairs. Burnout in chairs of obstetrics and gynecology is characterized by a high level of emotional exhaustion, moderate-high depersonalization, and

    2002-01-01

    During the last two decades, the field of in vitro technology has been successfully developed and its use is continuously growing. Advanced tests avoiding animal experiments will be increasingly required for routine industrial applications e.g. for pharmacological high-throughput screening. Moreover and even more importantly, the availability of human cell based methods is essential for future quality assurance and risk assessment in the fields of health and consumer protection as well as environmental protection. Thereby, the potential of such advanced in vitro methods extends far beyond the mere replacement of regulated tests. In practice, the introduction and expansion of this technology has been achieved predominantly by offering funding and awards to the scientific community. After this initiation phase, the next consequent step to exploit this knowledge clearly consists in academic promotion of this new scientific culture in an institutionalised form. The tasks of such a chair focussed on advanced in vitro tests - most probably the first of its kind world-wide - would cover in addition to (a) research and (b) teaching, (c) the sharpening of social conscience for the topic. (a) While the validation of alternative methods was formally established by founding institutions like ZEBET in Berlin on the national and ECVAM in Ispra on the European level, the development of further new and more sophisticated in vitro methods to date emerge predominantly as a by-product of basic research. A considerable push might now be given by the structured search for new methods with a spill-over for research-based up-to-date teaching. (b) The field of alternative methods is more than a panel of advanced in vitro techniques: A culture of systematic evaluation and validation of in vitro tests has been developed, which has bearing far beyond the replacement of animal experiments. In vitro systems inherently prone to artefacts require the highest level of quality control and

    The United States (US) nuclear weapons program during the Cold War left a legacy of radioactive, hazardous, chemical wastes and facilities that may seriously harm the environment and people even today. Widespread public concern about the environmental pollution has created an extraordinary demand for the treatment and disposal of wastes in a manner to protect the public health and safety. The pollution abatement and environmental protection require an understanding of technical, regulatory, economic, permitting, institutional, and public policy issues. Scientists and engineers have a major role in this national effort to clean our environment, especially in developing alternative solutions and evaluation criteria and designing the necessary facilities to implement the solutions. The objective of the DOE Chair of Excellence project is to develop a high quality educational and research program in environmental engineering at North Carolina A&T State University (A&T). This project aims to increase the number of graduate and undergraduate students trained in environmental areas while developing a faculty concentrated in environmental education and research. Although A&T had a well developed environmental program prior to the Massie Chair grant, A&T's goal is to become a model of excellence in environmental engineering through the program's support. The program will provide a catalyst to enhance collaboration of faculty and students among various engineering departments to work together in a focus research area. The collaboration will be expanded to other programs at A&T. The past research focus areas include: hazardous and radioactive waste treatment and disposal fate and transport of hazardous chemicals in the environment innovative technologies for hazardous waste site remediation pollution prevention Starting from 2005, the new research focus was in the improvement of accuracy for radioactive contaminant transport models by ensemble based data assimilation

    Background Beach chair positioning during general anesthesia is associated with cerebral oxygen desaturation. Changes in cerebral oxygenation resulting from the interaction of inspired oxygen fraction, end-tidal carbon dioxide and anesthetic choice have not been fully evaluated in anesthetized patients in the beach chair position. Methods This was a prospective interventional within-group study of patients undergoing shoulder surgery in the beach chair position that incorporated a randomized comparison between two anesthetics. Fifty-six patients were randomized to receive desflurane or total intravenous anesthesia with propofol. Following induction of anesthesia and positioning, inspired oxygen fraction (Fio2) and minute ventilation were sequentially adjusted for all patients. Regional cerebral oxygenation (rSO2) was the primary outcome and was recorded at each of five set points. Results While maintaining Fio2 at 0.3 and end tidal carbon dioxide (PETCO2) at 30mmHg there was a decrease in rSO2 from 68%, SD 12 to 61%, SD 12 (pchair positioning. The combined interventions of increasing Fio2 to 1.0 and increasing Petco2 to 45mmHg resulted in a 14% point improvement in rSO2 to 75%, SD 12 (p chair position. There was no significant interaction effect of the anesthetic at the study intervention points. Conclusions Increasing Fio2 and Petco2 resulted in a significant increase in rSO2 that overcomes desaturation in patients anesthetized in the beach chair position and that appears independent of anesthetic choice.

    Directory of Open Access Journals (Sweden)

    Leontakianakou Irini

    2009-01-01

    Full Text Available This paper deals with a specific iconographic type of Archangel Michael: he is shown bearing a soul in the form of a swaddled infant, while subduing an old man who is wearing only a loincloth. Who is Michael subduing? Three possible answers are considered: 1 the figure can be identified with Satan the fallen angel who, like Michael, has an immaterial nature and is commonly considered as his enemy par excellence; 2 he can also be an anonymous sinner, whose soul is depicted in Michael's hand; 3 finally, one could identify him with Hades, the god of the Underworld and personification of death, because he is depicted as an old man, semi-nude with a pronounced musculature, as well as because of the assimilation of Michael to God. Rather than making a single choice, the author proposes a combined interpretation of the image, which allows for the integration of all the aspects of Michael's cult (military, triumph over Satan, psychopomp, archangel of the Last Judgment and unifies the past (the fall of Satan, the present (death of a sinner and the future (Last Judgment.

    Evidence supports that surgeons are at high risk for work-related musculoskeletal disorders. The objective of the study was to compare the effect of different chairs on work-related musculoskeletal discomfort for surgeons during vaginal operations. This crossover study randomly assigned 4 surgeons to 4 chair types using a 4 × 4 Latin square model: a conventional round stool, a round stool with a backrest, a saddle chair with a backrest, and a Capisco chair. Subjective assessments of surgeon discomfort were performed with a validated body discomfort survey, and workload was assessed with the surgical task load index. The objective postural load was quantified with inertial measurement units of the modified rapid upper limb assessment limits. Subjective and objective assessments of chair comfort were performed with an 11 point scale and seat interface pressure-mapped distributions, respectively. The primary outcome was the difference in body discomfort scores between pre- and postsurgery measurements. Secondary outcomes were the differences in chair comfort scores, postural load, and seating interface pressure-mapped distribution. For each outcome, comparisons among the chair types were based on fitting a linear mixed model that handled the surgeon as a random effect and the chair type as a fixed effect. Data were collected for 48 vaginal procedures performed for pelvic organ prolapse. Mean (SD) duration of surgery was 122.3 (25.1) minutes. Surgeons reported body discomfort during 31 procedures (67.4%). Subjective increase in discomfort from the preoperative state was noted most commonly in the lower back (n = 14, 30.4%), followed by right shoulder (n = 12, 26.1%), upper back (n = 8, 17.4%), hips and buttocks (n = 7, 15.2%), left shoulder (n = 6, 13.0%), right or left thigh (n = 6, 13.0%), and neck (n = 6, 13.0%). Pre- and postsurgery body discomfort scores did not differ with respect to chair type. Chair discomfort scores for the round stool and the saddle

    Purpose: Treating patients in a seated position has potential advantages including improved comfort, increased lung volume, and reduced respiratory motion. We compared chair designs for head and neck, thoracic and breast patients for use with either IGRT linacs or a proposed low-cost fixed horizontal beam-line machine. Methods: Three treatment chairs were designed and constructed. Two of the chairs are based on a massage-chair, with the patient angled slightly forwards and knee rests used to minimize intra-fraction slouch. The third chair design is more conventional; the patient is angled backwards, with indexed positioning devices and the ability to attach thermoplastic masks. Patient geometries, including PTV location and patient sizes, were extracted from 137 CTs of past patients were used to model the probability of collision between the patient and the linac for various seated positions. All chairs were designed around the weight limits for couches on our linacs. At the time of writing we have just received IRB approval for imaging studies to evaluate comfort, and intra- and interfraction reproducibility. Results: The geometric analysis showed that head and neck patients and thoracic patients could be treated without collision. However, there is very limited space between the patient and the treatment/imaging devices, so careful design of the chair is essential. The position of the treatment target and extended arm positioning means that this is a particular concern for thoracic and breast patients. This was demonstrated for one of the prototype chairs designed for breast treatment where the arm holders would collide with the kV detector. The extra clearance of a dedicated fixed-beam linac would overcome these difficulties. Intra- and inter-fraction reproducibility results will be presented at the meeting. Conclusion: To take advantage of the clinical advantages of seated treatments, appropriate treatment chairs are needed. A dedicate fixed-beam linac may

    Despite the strong representation of female psychiatrists in residency and early-career positions, the number of female faculty sharply decreases in tenured or executive leadership positions. Why there exists a marked change in representation at the level of senior leadership within academic psychiatry is unclear. The authors investigated the causative factors contributing to this observation and gathered information about the personal characteristics of women in executive leadership roles. The authors surveyed psychiatry chairs at academic institutions. They identified all female chairs and randomly selected a group of male chairs to serve as a control group. The survey assessed perceived barriers, strengths, and weaknesses and differences in demographics and leadership styles between female and male chairs. Ten percent of psychiatry chairs were female. Male chairs were more likely than female chairs to head large departments (p = 0.02, confidence interval (CI) -17.1-69.1) and had a higher H-index (p = 0.001, CI 6.6-37.2). Female chairs were more likely than male chairs to perceive barriers in their career development (p = 0.01, CI 0.7-2.2), citing little or no mentorship (p = 0.04), gender discrimination (p = 0.0001), and family obligations (p = 0.001) more often. Academic institutions must incorporate programs to decrease barriers and work to achieve equitable representation of women in upper-level leadership positions. Moreover, academic medicine must evolve to cultivate a family-friendly environment that successfully supports both genders.

    This study examined the perceived psychosocial functions of flashbulb memories: It compared positive and negative public flashbulb memories (positive: Bin Laden's death, negative: Michael Jackson's death) with private ones (positive: pregnancy, negative: death of a loved one). A sample of n = 389 young and n = 176 middle-aged adults answered canonical category questions used to identify flashbulb memories and rated the personal significance, the psychological temporal distance, and the functions of each memory (i.e., self-continuity, social-boding, directive functions). Hierarchical regressions showed that, in general, private memories were rated more functional than public memories. Positive and negative private memories were comparable in self-continuity and directionality, but the positive private memory more strongly served social functions. In line with the positivity bias in autobiographical memory, positive flashbulb memories felt psychologically closer than negative ones. Finally, middle-aged adults rated their memories as less functional regarding self-continuity and social-bonding than young adults. Results are discussed regarding the tripartite model of autobiographical memory functions.

    The stereocontrolling transition state (TS) models for C-C bond formation relying on hydrogen bonding have generally been successful in proline-catalyzed aldol, Mannich, α-amination, and α-aminoxylation reactions. However, the suitability of the hydrogen-bonding model in protic and aprotic conditions as well as under basic and base-free conditions has not been well established for Michael reactions. Through a comprehensive density functional theory investigation, we herein analyze different TS models for the stereocontrolling C-C bond formation, both in the presence and absence of a base in an aprotic solvent (THF). A refined stereocontrolling TS for the Michael reaction between cyclohexanone and nitrostyrene is proposed. The new TS devoid of hydrogen bonding between the nitro group of nitrostyrene and carboxylic acid of proline, under base-free conditions, is found to be more preferred over the conventional hydrogen-bonding model besides being able to reproduce the experimentally observed stereochemical outcome. A DBU-bound TS is identified as more suitable for rationalizing the origin of asymmetric induction under basic reaction conditions. In both cases, the most preferred approach of nitrostyrene is identified as occurring from the face anti to the carboxylic acid of proline-enamine. The predicted enantio- and diastereoselectivities are in very good agreement with the experimental observations.

Because these exercise modalities require a controlled environment which limits their use by pulmonologists and severely restricts their use among general practitioners, different modalities of a short (1 minute or less sit-to-stand test were recently proposed. In this study, we evaluated a new modality of a semipaced 3-minute chair rise test (3CRT in 40 patients with COPD, and compared the reproducibility of physiological responses and symptoms during the 3CRT and their interchangeability with the 6MWT. The results demonstrate that physiological variables, heart rate, pulse oxygen saturation, work done, and symptoms (Borg dyspnea and fatigue scores, during the 3CRT were highly reproducible, and that the physiological responses and symptoms obtained during the 3CRT and the 6MWT were interchangeable for most patients. Moreover, these preliminary data suggest that patients able to perform more than 50 rises during 3 minutes had no significant disability. The simplicity and ease of execution of the 3CRT will facilitate the assessment of exercise symptoms and disability in COPD patients during routine consultations with pulmonologists and general practitioners, and will thus contribute

    Full Text Available The nitrogen containing spiro-heterocycle is one of the privileged synthetic motif that constitutes various naturally occurring molecules and displays a broad range of pharmaceutical and biological activities. A new methodology was developed for the synthesis of 2,4-diazaspiro[5.5]undecane-1,3,5,9-tetraones spiro-heterocyclic derivatives via cascade cyclization of [5+1] double Michael addition reaction of N,N-dimethylbarbituric acid with the derivatives of diaryldivinylketones in the presence of diethylamine at ambient temperature. The developed protocol is highly capable of furnishing diazaspiro[5.5]undecane derivatives 3a–m in excellent yields (up to 98%, from easily accessible symmetric and non-symmetric divinylketones 2a–m, containing aryl and heteroaryl substituents. The diazaspiro-heterocyclic structure was mainly elucidated by NMR and X-ray crystallographic techniques. The single-crystal X-ray studies revealed that, the cyclohexanone unit of spirocycles often prefers a chair conformation rather than twisted conformation. The intermolecular hydrogen bonding and CArH⋯π, π–π stacking interactions driving forces are mainly responsible for the crystal packing.

    Full Text Available Background: Most dentists complain of musculoskeletal disorders which can be caused by prolonged static posture, lack of suitable rest and other physical and psychological problems. Objective: We evaluated a chair with a new ergonomic design which incorporated forward leaning chest and arm supports. Methods: The chair was evaluated in the laboratory during task simulation and EMG analysis on 12 students and subjectively assessed by 30 professional dentists using an 18-item questionnaire. EMG activity of right and left trapezius muscles for 12 male students with no musculoskeletal disorders was measured while simulating common tasks like working on the teeth of the lower jaw. Results: Normalized EMG data showed significant reduction (p<0.05 in all EMG recordings of the trapezius muscle. Dentists also unanimously preferred the ergonomically designed chair. Conclusion: Such ergonomically designed chairs should be introduced as early as possible in student training before bad postural habits are acquired.

    Gender-based bias and conflation of gender and status are root causes of disparities in women's health care and the slow advancement of women to leadership in academic medicine. More than a quarter of women physicians train in internal medicine and its subspecialties, and women physicians almost exclusively constitute the women's health focus within internal medicine. Thus, internal medicine has considerable opportunity to develop women leaders in academic medicine and promote women's health equity.To probe whether holding an endowed chair-which confers status-in women's health may be an effective way to advance women leaders in academic medicine and women's health, the authors explored the current status of endowed chairs in women's health in internal medicine. They found that the number of these endowed chairs in North America increased from 7 in 2013 to 19 in 2015, and all were held by women. The perceptions of incumbents and other women's health leaders supported the premise that an endowed chair in women's health would increase women's leadership, the institutional stature of women's health, and activities in women's health research, education, and clinical care.Going forward, it will be important to explore why not all recipients perceived that the endowed chair enhanced their own academic leadership, whether providing women's health leaders with fundraising expertise fosters future success in increasing the number of women's health endowed chairs, and how the conflation of gender and status play out (e.g., salary differences between endowed chairs) as the number of endowed chairs in women's health increases.

    Rearranging furniture in elementary school classrooms encourages classroom activities. In elementary schools in Indonesia and some other developing countries, usually only one style of furniture is used for all children, and the furniture is heavy and oversized for younger children. This affects their ability to carry it. The objective of this study is to investigate the effects of elementary school furniture weight and children’s age on performance of three carrying tasks (carrying a chair, lifting and turning a chair on a desk, and carrying both a chair and a desk together), from the ergonomics point of view. A total of 42 schoolchildren (ages 6–9; 17 Indonesian, 25 Japanese) participated in this study. Two types of Japanese chairs (Chair A and B, weight: 3.2 kg and 3.9 kg), one type of Indonesian chair (Chair C, weight: 5.0 kg), and two types of desks (height: 58 cm and 68 cm) were used. Indonesian chairs took significantly longer time to carry than the two Japanese chairs, and there was a significant negative relationship between age and task time for Chairs B and C, but not Chair A. Success rates for lifting and turning the chair declined as age decreased and chair weight increased, but were not significantly influenced by desk height. Success rates for carrying a chair and desk together significantly decreased with heavier furniture. Children aged six showed an extremely low success rate in almost all conditions. In conclusion, children’s ability to carry furniture is affected by their age and furniture characteristics, especially weight. In order to encourage classroom activities in elementary school, school furniture should be of appropriate weight. Supervision for younger children is required during classroom furniture arrangement.

    Regardless of the constantly increasing time man is spending in a sitting position, there is still a lack of objective chair quality assessment criteria. The aim of this paper is to find the answer to whether respiratory chest movement measurements can be a chair quality indicator. The study included 34 participants (mean 34.7 years ± 5.2). Their chest movements were assessed using respiratory inductive plethysmography while sitting on two subsequent chairs. Significant differences in chest movements depending on chair type were observed concerning the breathing duct (upper and lower) and breathing movement amplitude. The amplitude of the upper respiratory track in the first chair was higher (239.4 mV) compared with the second seat (207.3 mV) (p = .018). The analyzed parameters of respiratory chest movement may become a helpful indicator for design and selection of chairs which enable people to both work and relax in the most ergonomic conditions.

    The newly formed Alliance of Directors and Vice Chairs of Education in Radiology (ADVICER), a group within the Alliance for Clinician Educators in Radiology, identified an acute need for a generic job description template for Vice Chairs of Education in Radiology, a role that is being developed in many academic Departments of Radiology. Eighty-three percent of current members who responded to a survey had no detailed job description, and over half had no job description at all. Having a comprehensive and detailed job description is vital to developing this key position. Using the results of a survey sent to ADVICER members and seven Education Vice Chair job descriptions provided by members, the authors developed a detailed job description encompassing all potential elements of this position. Only 17% of survey respondents had a detailed job description. The role of an Education Vice Chair varies significantly between institutions in its scope and level of responsibilities. The resultant generic job description that was devised is intended to provide a template that would be modified by the candidate or the Department Chair. It is unlikely that any one individual would perform all the described activities. ADVICER has developed a comprehensive, flexible job description for Vice Chair of Education in Radiology that can be adapted by institutions as appropriate.

    Conflicting studies exist about the effectiveness of cardiopulmonary resuscitation (CPR) on a dental chair. In some situations, dental surgeons are obliged to perform CPR with the patient on the chair. Feedback devices are supposed to guide the compression depth in order to improve the quality of CPR, but some devices are based on an accelerometer that can theoretically report erroneous results because of the lack of rigidity of a dental chair. The aim of this study was to evaluate the accuracy of these devices to guide chest compressions on a dental chair. A prospective, randomised, crossover, equivalence/non-inferiority study was conducted to compare the values of compression depths provided by the feedback device (Real CPR Help(®), delivered by Zoll© Medical Corporation, Chelmsford, MA, USA) with the real measurements provided by the manikin (Resusci Anne(®) Advanced SkillTrainer, Laerdal Medical AS©, Norway). Chest-compression-only CPR was performed by 15 Basic Life Support instructors who carried out two rounds of continuous CPR for 2 min each. Data were analysed with a correlation test, a Bland-Altman method and a Wilcoxon test. Statistical significance was defined as pdental chair and on the floor (pdental chairs.

    Energy use in offices buildings is largely driven by air conditioning demands. But the optimal temperature is not the same for all building occupants, leading to the infamous thermostat war. And many occupants have independently overcome building comfort weaknesses with their own space heaters or fans. NREL tested is a customized office chair that automatically heats and cools the occupant along the seat and chair back according to the occupants' personal preferences. This product is shown to deliver markedly better comfort at room temperatures well above typical office cooling setpoints. Experimental subjects reported satisfaction in these elevated air temperatures, partly because the chair's cooling effect was tuned to their own individual needs. Simulation of the chair in office buildings around the U.S. shows that energy can be saved everywhere, with impacts varying due to the climate. Total building HVAC energy savings exceeded 10% in hot-dry climate zones. Due to high product cost, simple payback for the chair we studied is beyond the expected chair life. We then understood the need to establish cost-performance targets for comfort delivery packages. NREL derived several hypothetical energy/cost/comfort targets for personal comfort product systems. In some climate regions around the U.S., these show the potential for office building HVAC energy savings in excess of 20%. This report documents this research, providing an overview of the research team's methods and results while also identifying areas for future research building upon the findings.

  2. Do institutional logics predict interpretation of contract rules at the dental chair-side?

    2014-12-01

    In quasi-markets, contracts find purchasers influencing health care providers, although problems exist where providers use personal bias and heuristics to respond to written agreements, tending towards the moral hazard of opportunism. Previous research on quasi-market contracts typically understands opportunism as fully rational, individual responses selecting maximally efficient outcomes from a set of possibilities. We take a more emotive and collective view of contracting, exploring the influence of institutional logics in relation to the opportunistic behaviour of dentists. Following earlier qualitative work where we identified four institutional logics in English general dental practice, and six dental contract areas where there was scope for opportunism; in 2013 we surveyed 924 dentists to investigate these logics and whether they had predictive purchase over dentists' chair-side behaviour. Factor analysis involving 300 responses identified four logics entwined in (often technical) behaviour: entrepreneurial commercialism, duty to staff and patients, managerialism, public good.

    Full Text Available Introduction. Frail older people are often unable to undertake high-intensity exercise programmes. Chair-based exercises (CBEs are used as an alternative, for which health benefits are uncertain. Objective. To examine the effects of CBE programmes for frail older people through a systematic review of existing literature. Method. A systematic search was performed for CBE-controlled trials in frail populations aged ≥65 years published between 1990 and February 2011 in electronic databases. Quality was assessed using the Jadad method. Results. The search identified 164 references: with 42 duplicates removed, 122 reviewed, 116 excluded, and 6 analysed. 26 outcome measures were reported measuring 3 domains: mobility and function, cardiorespiratory fitness, mental health. All studies were of low methodological quality (Jadad score ≤2; possible range 0–5. Two studies showed no benefit, and four reported some evidence of benefit in all three domains. No harmful effects were reported; compliance was generally good. Conclusion. The quality of the evidence base for CBEs is low with inconclusive findings to clearly inform practice. A consensus is required on the definition and purpose of CBEs. Large well-designed randomised controlled trials to test the effectiveness of CBE are justified.

    This paper reviews how dental chair unit (DCU) manufacturers can contribute practically to resolving the problem of biofilm formation in dental unit waterlines (DUWs). The review concentrates on how novel developments and changes in a range of specific areas have, and might contribute to DUW biofilm control. These include (i) DCU engineering and design changes; (ii) improvements to DCU supply water quality; (iii) development of automated DUW treatment procedures that are effective at controlling biofilm in the long-term, safe for patients and dental staff, environmentally friendly and which do not exhibit adverse effects on DCU components after prolonged use. The majority of the material contained in this review is based on, or supported by the peer-reviewed literature. The current consensus from the literature reveals that the emphasis on DUW biofilm and its control has focused on describing the problem and its control using a range of periodic and residual DUW treatment agents. Unfortunately, until recently, DCU manufacturers have provided very little specific guidance in this regard. Indeed, ensuring that DCUs provide good quality output water has generally been regarded to be the responsibility of dental practitioners. Some recent studies have shown that novel DCUs with integral semi-automated or automated DUW cleaning systems can effectively control DUW biofilm in the long-term. However, there are other potential DCU engineering and design changes that DCU manufacturers could undertake to further improve DUW biofilm control. DCU manufacturers can significantly contribute to controlling the problem of DUW biofilm.

    Full Text Available The use of a simple weak inorganic base such as potassium carbonate facilitated the formation of carbon-carbon bonds through both the Henry and the Michael reactions with nitrocompounds. The application of this catalyst under environmentally friendly solventless heterogeneous conditions gave satisfactory to good yields of β-nitroalcohols, involving aliphatic and aromatic starting materials, as well as high to excellent yields in the formation of Michael adducts using several different Michael acceptors and nitroalkanes.

  7. ‘Introducing Michael Gove to Loïc Wacquant’: Why Social Work Needs Critical Sociology

    Science.gov (United States)

    Michael Garrett, Paul

    2016-01-01

    In 2013, Michael Gove, then Secretary of State for Education and Health in the UK coalition government, criticised social workers for laying insufficient emphasis on the ‘agency’ of individuals and for being too preoccupied with social and economic inequalities. Such a perspective, which is not unique to Gove, needs to be countered by reaffirming the significance of an expansively critical sociology for social work. In this context, the thematic concerns of the French theorist, Loïc Wacquant, illuminates key aspects of social work engagement with clients which Gove and his ideological associates appear intent on ignoring. The issues raised have significant political resonances given the pending UK General Election taking place in May 2015. PMID:27559203

    This paper systematically reviews the effect of chair backrests and reducing seated hip flexion on low back discomfort (LBD) and trunk muscle activation. Prolonged sitting commonly exacerbates low back pain (LBP). Several modifications to seated posture and chair design have been recommended, including using chairs with backrests and chairs that reduce hip flexion. Electronic databases were searched by two independent assessors. Part 1 of this review includes 26 studies comparing the effect of sitting with at least two different hip angles. In Part 2, seven studies that compared the effect of sitting with and without a backrest were eligible. Study quality was assessed using the PEDro scale. Significant confounding variables and a relatively small number of randomized controlled trials (RCTs) involving people with LBP complicates analysis of the results. There was moderate evidence that chair backrests reduce paraspinal muscle activation, and limited evidence that chair backrests reduce LBD. There was no evidence that chairs involving less hip flexion reduce LBP or LBD, or consistently alter trunk muscle activation. However, participants in several studies subjectively preferred the modified chairs involving less hip flexion. The limited evidence to support the use of chairs involving less seated hip flexion, or the effect of a backrest, is consistent with the limited evidence that other isolated chair design features can reduce LBP. LBP management is likely to require consideration of several factors in addition to sitting position. Larger RCTs involving people with LBP are required. © 2015, Human Factors and Ergonomics Society.

    The concept of an ideal sitting posture is often used in practice but lacks a basis in evidence. We designed a cross-sectional, comparative, matched study to determine the effects of chair and posture on lumbar curvature in 10 patients with chronic non-specific low back pain (CLBP; mean pain duration 24 ± 18 months) and 10 healthy matched controls. Pelvic incidence, sacral slope and lumbar curvature were measured on computed radiographs by 2 blinded clinicians for subjects in 2 postures (upright vs slumped sitting) and on 2 chairs (usual flat chair vs kneeling chair). The reliability of measures was excellent (intraclass correlation coefficient>0.9). As hypothesized, the expected sacral slope and lumbar lordosis changed between standing and sitting on a kneeling chair as compared with a usual chair (Pchairs and postures for lumbar lordosis (P=0.02) indicated more pronounced effects of the chair in slumped sitting. Therefore, lumbar lordosis was reduced less when sitting on a kneeling chair as compared with a usual chair. Although healthy subjects showed more reduction in lordosis between standing and sitting, the chair effect was found in both CLBP patients and healthy subjects. Copyright © 2015 Elsevier Masson SAS.

    2012-02-01

    Specially designed chairs are expensive. A hand-made chair easily constructed from recycled material can be an alternative option. However data on the feasibility of hand-made chair use at home is limited. The present study aimed to explore the usage of a hand-made chair at home in children with moderate to severe motor disabilities. Seventeen children with cerebral palsy were recruited. Main caregivers were interviewed regarding the possibility of using the chair at home. Home visits and observations were also performed to explain how the chair had been used at home. Nine children (52.9%) used the chair everyday. Seven of these nine children were seated at least 30 minutes each time and two to three times per day. The total time that children spent on the hand-made chair each day ranged from 10 to 90 minutes. The severity of disability and main caregivers' workload may explain an inadequate usage of the hand-made chair. A few modifications may help to improve the applicability of the hand-made chair.

    Full Text Available Aza-Michael reactions between primary aliphatic and aromatic amines and various Michael acceptors have been performed under environmentally-friendly solventless conditions using acidic alumina as a heterogeneous catalyst to selectively obtain the corresponding mono-adducts in high yields. Ethyl acrylate was the main acceptor used, although others such as acrylonitrile, methyl acrylate and acrylamide were also utilized successfully. Bi-functional amines also gave the mono-adducts in good to excellent yields. Such compounds can serve as intermediates for the synthesis of anti-cancer and antibiotic drugs.

    Full Text Available The copper-catalyzed asymmetric conjugate addition (ACA of nucleophiles onto polyenic Michael acceptors represents an attractive and powerful methodology for the synthesis of relevant chiral molecules, as it enables in a straightforward manner the sequential generation of two or more stereogenic centers. In the last decade, various chiral copper-based catalysts were evaluated in combination with different nucleophiles and Michael acceptors, and have unambiguously demonstrated their usefulness in the control of the regio- and enantioselectivity of the addition. The aim of this review is to report recent breakthroughs achieved in this challenging field.

    Full Text Available Objective: To assess academic emergency medicine (EM chairs’ perceptions of quality improvement (QI training programs.Methods: A voluntary anonymous 20 item survey was distributed to a sample of academic chairs of EM through the Association of Academic Chairs of Emergency Medicine. Data was collected to assess the percentage of academic emergency physicians who had received QI training, the type of training they received, their perception of the impact of this training on behavior, practice and outcomes, and any perceived barriers to implementing QI programs in the emergency department.Results: The response rate to the survey was 69% (N = 59. 59.3% of respondents report that their hospital has a formal QI program for physicians. Chairs received training in a variety of QI programs. The type of QI program used by respondents was perceived as having no impact on goals achieved by QI (χ2 = 12.382; p = 0.260, but there was a statistically significant (χ2 = 14.383; p = 0.006 relationship between whether or not goals were achieved and academic EM chairs’ perceptions about return on investment for QI training. Only 22% of chairs responded that they have already made changes as a result of the QI training. 78.8% of EM chairs responded that quality programs could have a significant positive impact on their practice and the healthcare industry. Chairs perceived that QI programs had the most potential value in the areas of understanding and reducing medical errors and improving patient flow and throughput. Other areas of potential value of QI include improving specific clinical indicators and standardizing physician care.Conclusion: Academic EM chairs perceived that QI programs were an effective way to drive needed improvements. The results suggest that there is a high level of interest in QI but a low level of adoption of training and implementation.[West J Emerg Med. 2010; 11(5:479-485.

    Individuals with limited mobility can spend prolonged periods in leisure chairs, increasing their risk of developing a seated acquired pressure ulcer. The present study aims to use objective measures of posture and tissue viability to identify the associated risks of leisure chair related pressure ulcers. Healthy participants (n = 13) were recruited to sit on a leisure chair with either a viscoelastic foam or air cushion. Participants were asked to adopt four different postures for a period of 10 min followed by a 10 min refractory period. Measurements at the leisure chair-participant interface included interface pressure, transcutaneous tissue gas tensions at the ischial tuberosities, accelerometer data collected from the sternum and subjective comfort levels. Results indicated that interface pressures remained consistent, with peak pressure index values of less than 60 mmHg across all conditions. A proportion of participants exhibited decreased oxygen tensions associated with increased carbon dioxide tensions during one or more test condition. This was particularly prevalent during the right lean posture on the air cushion (46%). In all cases, normal tissue viability was restored during standing. The accelerometer was able to detect significant changes (p chairs have little evidence to support their pressure relieving properties. This study revealed that a proportion of healthy individuals demonstrated a compromised tissue viability in specific postures. Further research is required to assess the impact of these sitting conditions in vulnerable individuals. Copyright © 2017 Tissue Viability Society. Published by Elsevier Ltd. All rights reserved.

    To know the effectiveness of a custom molded fitting chair between pre- and post-chair status through comparison of musculoskeletal indices in severely disabled children. We researched 34 severely disabled patients who had used a custom molded fitting chair continuously for more than a year. There were 27 cerebral palsy patients and 7 patients with other kinds of diseases that affect the brain such as chromosomal disease or metabolic disease. By radiographic studies, Cobb's angle, the femoral neck-shaft angle of the femur, and Reimers migration percentage were measured. The indices are analyzed before and after application. The average period of application was 24 months. There was a significant reduction in the angles of femur neck-shaft, 163.4 degree before and 158.2 degree after the use of the chair (pchair status was not statistically significant. Seventeen of 33 children showed reduced Cobb's angle. Also, 19 of 37 showed a reduced degree of dislocation of the hip joints. In spite of the use of a custom molded fitting chair, a significant improvement did not emerge for musculoskeletal deformity indices in severely disabled children. However, there was no significant aggravation of Cobb's angle or Reimers migration percentage in developing children. Therefore, it is thought be helpful to prevent rapid aggravation of musculoskeletal deformities.

    Dell, M

    1998-01-01

    Michael Dell started his computer company in 1984 with a simple business insight. He could bypass the dealer channel through which personal computers were then being sold and sell directly to customers, building products to order. Dell's direct model eliminated the dealer's markup and the risks associated with carrying large inventories of finished goods. In this interview, Michael Dell provides a detailed description of how his company is pushing that business model one step further, toward what he calls virtual integration. Dell is using technology and information to blur the traditional boundaries in the value chain between suppliers, manufacturers, and customers. The individual pieces of Dell's strategy--customer focus, supplier partnerships, mass customization, just-in-time manufacturing--may be all be familiar. But Michael Dell's business insight into how to combine them is highly innovative. Direct relationships with customers create valuable information, which in turn allows the company to coordinate its entire value chain back through manufacturing to product design. Dell describes how his company has come to achieve this tight coordination without the "drag effect" of ownership. Dell reaps the advantages of being vertically integrated without incurring the costs, all the while achieving the focus, agility, and speed of a virtual organization. As envisioned by Michael Dell, virtual integration may well become a new organizational model for the information age.

    2016-07-01

    Conclusion In the present study, therapy balls and or cushioned chairs for ASD students facilitated in-seat and on-task behaviors and improved classroom performance. It seems that using these alternative seating chairs can satisfy the subjects’ needs to sensory stimuli, and therefore, decreases their sensory seeking behaviors which interferes with their academic achievements. While, using therapy ball chairs for these students may facilitate in-seat behavior and decrease autistic behavior in class, the student’s response to dynamic seating is different individually. Therefore, chair selection must be based on vestibular reaction of the students.

    Medical imaging education often has limited representation in formal medical student curricula. Although the need for greater inclusion of radiology material is generally agreed on, the exact skillset that should be taught is less clear. The purpose of our study was to perform a needs assessment for a national radiology curriculum for medical students. We analyzed data from previous unpublished portions of the American College of Radiology/Alliance of Medical Student Educators in Radiology survey of Deans and Radiology Chairs regarding prevalence of radiology curricular revisions, assessment tools, use of the American College of Radiology Appropriateness Criteria, and resources used in curriculum revision. We also performed a literature search through both PubMED and a general search engine (Google) to identify available resources for designing and implementing imaging curricula and curricular revisions. Medical school deans and chairs reported a need for more overall radiology content; one of every six programs (15%) reported they had no recognized imaging curriculum. Of schools currently with imaging curricula, 82% have undergone revision in the last 10 years using a variety of different resources, but there is no universally agreed on guide or standard curriculum. The PubMED and Google searches identified only 23 and eight resources, respectively, suggesting a sizable deficit in available guidance; however, a single published medical student radiology curriculum is available through the Alliance of Medical Student Educators in Radiology. There is a need, but few available resources, to guide educators in adding imaging content to medical school curricula. We postulate that a standardized national curriculum directed by a focused skillset may be useful to educators and could result in greater uniformity of imaging skills among graduating US medical students. A proposed skillset to guide a national curriculum in radiology is described. Copyright © 2015 AUR

  20. The Professorial Chair (kursī ‘ilmī or kursī li-l-wa‘ẓ wa-l-irshād in Morocco

    Full Text Available Moroccan congregational mosques are equipped with a minbar (pulpit which is used for the Friday sermon. Many mosques in Morocco are also equipped with one or more smaller chairs, which differ in their form and function from the minbar. These chairs are used by professors to give regular lectures to students of traditional education, and by scholars to give occasional lectures to the general public. This tradition of the professorial chair was probably introduced to Morocco from the Middle East in the thirteenth century. Most of the existing chairs in Morocco seem to date from the nineteenth and twentieth centuries, and they continue to be made and used today. The chairs always have two steps, a seat, a backrest and armrests. This form probably evokes the original minbar of the Prophet in Medina, which had two steps and a seat, and this is one of many aspects of the conservatism and se parate evolution of Moroccan Malikism.Las mezquitas congregacionales en Marruecos suelen tener un almimbar (p?lpito que se utiliza durante el sermón de los viernes. Muchas mezquitas de Marruecos cuentan también con una o más sillas, diferenciadas del almimbar en su forma y su función ya que son utilizadas por los profesores para ensenar a los estudiantes de la educación tradicional, y por eruditos que dan conferencias ocasionales al p?blico en general. Esta tradición de cátedras se introduce probablemente en Marruecos desde Próximo Oriente en el siglo XIII. La mayoría de las cátedras existentes parecen datar de los siglos XIX y XX, manteniéndose hasta nuestros días la fabricación y utilización de estas sillas. Las cátedras siempre tienen dos peldanos, un asiento, un respaldo y apoyabrazos. La forma de las sillas parece evocar el almimbar original del Profeta en Medina, tradición que se muestra como uno de los muchos aspectos del conservadurismo y de la evolución distinta del Malikismo marroquí.

    [Purpose] This study investigated lumbar muscle fatigue before and after maintaining a seated position for one hour, lumbar and pelvic inclination angle change, in subjects with and without active lumber support. [Subjects and Methods] Fourteen healthy subjects randomized into two groups sat on a floor chair, placed on an office chair, that cyclically changed its lumbar supporting shape to provide active lumbar support (ALS) or no ALS for one hour. Before and after, we measured the frequency of muscle waveforms of the trunk extensor muscles when the subjects lifted an object weighing 10% of their body weight, using both hands while seated. In addition, ROMt (Range of motion test) of trunk rotation, degree of fatigue and muscle stiffness were analyzed. [Results] Muscle frequency while lifting the weight decreased significantly without ALS compared to with ALS. Mean muscle stiffness increased, ROMt decreased in desk work task significantly without ALS compared to with ALS. [Conclusion] These results suggest that the lumbar muscles became fatigued, because low frequencies, increased muscle stiffness, and decreased ROMt without ALS. We suggest lumbar muscle fatigue was maintained low for subjects seated in a chair with ALS.

    Prolonged sitting has been associated with musculoskeletal dysfunction. For desk workers, workstation modifications frequently address the work surface and chair. Chairs which can prevent abnormal strain of the neuromuscular system may aid in preventing musculo-skeletal pain and discomfort. Anecdotally, adjustability of the seat height and the seat pan depth to match the anthropometrics of the user is the most commonly recommended intervention. Within the constraints of the current economic climate, employers demand evidence for the benefits attributed to an investment in altering workstations, however this evidence-base is currently unclear both in terms of the strength of the evidence and the nature of the chair features. The purpose of this study was to evaluate the evidence for the effectiveness of chair interventions in reducing workplace musculoskeletal symptoms. Pubmed, Cinahl, Pedro, ProQuest, SCOPUS and PhysioFocus were searched. 'Ergonomic intervention', 'chair', 'musculoskeletal symptoms', 'ergonomics', 'seated work' were used in all the databases. Articles were included if they investigated the influence of chair modifications as an intervention; participants were in predominantly seated occupations; employed a pre/post design (with or without control or randomising) and if the outcome measure included neuro-musculoskeletal comfort and/or postural alignment. The risk of bias was assessed using a tool based on The Cochrane Handbook. Five studies were included in the review. The number of participants varied from 4 to 293 participants. Three of the five studies were Randomised Controlled Trials, one pre and post-test study was conducted and one single case, multiple baselines (ABAB) study was done. Three studies were conducted in a garment factory, one in an office environment and one with university students. All five studies found a reduction in self-reported musculoskeletal pain immediately after the intervention. Bias was introduced due to poor

    The leadership position of an academic departmental chair can be a positive and rewarding opportunity. These rewards principally stem from the success of the faculty, residents, other trainees, nurses, and everyone supporting the department. With health care reform and the constraints of the federal budget, increasing attention and time has become directed toward administrative management. There are multiple and often competing constituencies and agendas requiring thoughtful strategies to achieve departmental goals. The objectives of a chair are advancing patient care, education, and research. True excellence of a department is achieved by the innovation of its faculty. © 2015 The Authors.

    2012-01-01

    Low back pain (LBP) is a common musculoskeletal disorder and prolonged sitting often aggravates LBP. A novel dynamic ergonomic chair ('Back App'), which facilitates less hip flexion while sitting on an unstable base has been developed. This study compared lumbar posture and trunk muscle activation on this novel chair with a standard backless office chair. Twelve painfree participants completed a typing task on both chairs. Lumbar posture and trunk muscle activation were collected simultaneously and were analysed using paired t-tests. Sitting on the novel dynamic chair significantly (p 0.05) between chairs. Maintaining lordosis with less muscle activation during prolonged sitting could reduce the fatigue associated with upright sitting postures. Studies with longer sitting durations, and in people with LBP, are required. Sitting on a novel dynamic chair resulted in less lumbar flexion and less back muscle activation than sitting on a standard backless office chair during a typing task among pain-free participants. Facilitating lordotic sitting with less muscle activation may reduce the fatigue and discomfort often associated with lordotic sitting postures.

    2011-08-01

    Full Text Available INTRODUCTION: We present the initial experience of a novel surgical chair for laparoscopic pelvic surgery, the ETHOS TM (Bridge City Surgical, Portland, OR. MATERIALS AND METHODS: The ETHOS chair has an adjustable saddle height that ranges from 0.89 to 1.22 m high, an overall width of 0.89 m, and a depth of 0.97 m. The open straddle is 0.53 m and fits most OR tables. We performed 7 pelvic laparoscopy cases with the 1st generation ETHOS TM platform including 2 laparoscopic ureteral reimplantations, 5 laparoscopic pelvic lymphadenectomies for staging prostate cancer in which one case involved a laparoscopic radical retropubic prostatectomy, performed by 2 different surgeons. RESULTS: All 7 pelvic laparoscopic procedures were successful with the ETHOS TM chair. No conversion to open surgery was necessary. Survey done by surgeons after the procedures revealed minimal stress on back or upper extremities by the surgeons from these operations even when surgery was longer than 120 minutes. Conversely, the surgical assistants still had issues with their positions since they were on either sides of the patient stressing their positions during the procedure. CONCLUSION:The ETHOS chair system allows the surgeon to operate seated in comfortable position with ergonomic chest, arms, and back supports. These supports minimize surgeon fatigue and discomfort during pelvic laparoscopic procedures even when these procedures are longer than 120 minutes without consequence to the patient safety or detrimental effects to the surgical team.

    Special Region of Yogyakarta (DIY) is known as city for academic. Many people come to get some education in college. They live in boarding house with some supporting facilities. The most common facilities is low table which lead students have to sit on the floor while studying on table which could cause higher risk of back pain and musculoskeletal disorder. To identify the solution to reduce back pain and musculoskeletal risk, it is needed to design a lesehan chair which also appropriate to customer needs. Kansei engineering method was used with a total of 30 respondents participated, 15 kansei words collected, and 12 kansei words selected by doing validation and reliability test. The result of this study showed that quality, aesthetics, and comfort level influence the design of lesehan chair. A design of lesehan chair was created by considering the suitable concept and merging it with the physical design and its anthropometry measurement. In this case, marginal homogeneity test is needed to identify the differences between each kansei words attribute and the design or product recommendation. The marginal homogeneity test results show that the design and product recommendation has fulfilled customer's desires and needs. For further research, it is needed to analyse and evaluate the posture of lesehan chair users in order to develop and improve its performance.

    The aim of this study was to evaluate the commercial chair-side assays Saliva-Check Mutans and ClinproTM Cario L-PopTM in high microbiological caries-risk dental students compared with conventional semi-quantitative colony counting culture-based technique as the reference method. Saliva samples from 93 subjects of both sexes aged 18-26 years were seeded (Köhler and Bratthall method) on plates containing SB-20M culture medium method and 12 subjects with high caries risk were selected. These 12 individuals were subjected to determination of caries risk using two commercial rapid detection chair-side assays (Saliva-Check Mutans and ClinproTM Cario L-PopTM) according to the manufacturers' instructions. The results were analyzed by the Kappa correlation test using SAS statistical software. There was a perfect agreement (Kappa=1) among the three caries risk evaluation methods - chair-side assays and semi-quantitative CFU count (control) - in all subjects. The results suggest that the commercial chair-side assays evaluated in this study may be practical and useful to identify high microbiological caries-risk subjects.

    Varying the inclination of the dental chair backrest might alter the distribution of occlusal contact points. The purpose of this study was to identify the influence of backrest inclination on the registration of the mandibular position. Ten participants aged between 18 and 30 years with a complete permanent dentition, uncompromised motor function, no tooth mobility, and no temporomandibular disorders were selected. To register interocclusal contacts, an autopolymerizing methylmethacrylate device was adapted to the maxillary anterior teeth and a composite resin increment was added to the mandibular central incisors. Contacts were registered with the following variations in the inclination of the dental chair backrest: 90 degrees, 120 degrees, and 180 degrees. A standardized digital photograph was made of each mark in each backrest position, and the images were superimposed to measure the distances in registration from 90 to 120 and from 90 to 180 degrees. Data were analyzed with the Student paired t test (α=.05). When the chair was inclined from the 90-degree to the 120-degree position, the mandible was repositioned posteriorly by a mean of 0.67 mm, but the difference was not statistically significant. When the chair was inclined from the 90-degree to the 180-degree position, however, the mandible was repositioned posteriorly by a statistically significant mean of 1.41 mm. Mandibular position is influenced by increasing inclination, and this influence was statistically significant at a 180-degree incline.

    To investigate the association between sarcopenia and "chair stand test" performance, and evaluate this test as a screening tool for sarcopenia in community-dwelling elderly women. Cross-sectional Survey. 173 female individuals, aged ≥ 60 years and living in the urban area of the municipality of Lafaiete Coutinho, Bahia's inland, Brazil. The association between sarcopenia (defined by muscle mass, strength and/or performance loss) and performance in the "chair stand test" was tested by binary logistic regression technique. The ROC curve parameters were used to evaluate the diagnostic power of the test in sarcopenia screening. The significance level was set at 5 %. The model showed that the time spent for the "chair stand test" was positively associated (OR = 1.08; 95% CI = 1.01 - 1.16, p = 0.024) to sarcopenia, indicating that, for each 1 second increment in the test performance, the sarcopenia's probability increased by 8% in elderly women. The cut-off point that showed the best balance between sensitivity and specificity was 13 seconds. The performance of "chair stand test" showed predictive ability for sarcopenia, being an effective and simple screening tool for sarcopenia in elderly women. This test could be used for screening sarcopenic elderly women, allowing early interventions.

    2012-08-01

    Full Text Available Abstract Background Prolonged sitting has been associated with musculoskeletal dysfunction. For desk workers, workstation modifications frequently address the work surface and chair. Chairs which can prevent abnormal strain of the neuromuscular system may aid in preventing musculo-skeletal pain and discomfort. Anecdotally, adjustability of the seat height and the seat pan depth to match the anthropometrics of the user is the most commonly recommended intervention. Within the constraints of the current economic climate, employers demand evidence for the benefits attributed to an investment in altering workstations, however this evidence-base is currently unclear both in terms of the strength of the evidence and the nature of the chair features. The purpose of this study was to evaluate the evidence for the effectiveness of chair interventions in reducing workplace musculoskeletal symptoms. Methods Pubmed, Cinahl, Pedro, ProQuest, SCOPUS and PhysioFocus were searched. ‘Ergonomic intervention’, ‘chair’, ‘musculoskeletal symptoms’, ‘ergonomics’, ‘seated work’ were used in all the databases. Articles were included if they investigated the influence of chair modifications as an intervention; participants were in predominantly seated occupations; employed a pre/post design (with or without control or randomising and if the outcome measure included neuro-musculoskeletal comfort and/or postural alignment. The risk of bias was assessed using a tool based on The Cochrane Handbook. Results Five studies were included in the review. The number of participants varied from 4 to 293 participants. Three of the five studies were Randomised Controlled Trials, one pre and post-test study was conducted and one single case, multiple baselines (ABAB study was done. Three studies were conducted in a garment factory, one in an office environment and one with university students. All five studies found a reduction in self-reported musculoskeletal pain

    2012-11-01

    Full Text Available Michael Ondaatje's 2011 novel The Cat's Table follows a young boy's voyage from Colombo, Sri Lanka to London, England. Through this character and the unique environment of the ship, which forms a compelling sense of transitory place, Ondaatje explores liminality and its relationship with limitations or barriers. The young protagonist, Michael, and his companions enjoy an unusual level of freedom aboard the contained and hierarchically segmented ship. Polarization and transition between Eastern and Western culture is present but pales in importance compared to the validation of the self that is located within and defined by the sense of the in-between, an essential rite of passage undertaken before re-joining society.

    2015-01-01

    Despite 21 million US adults having a disability, little is known about the types of disabilities among faculty in family medicine departments, accommodations used, or work limitations. We surveyed family medicine department chairs electronically about the number, types of disabilities encountered, accommodations and associated costs, and attitudes toward family medicine faculty with disabilities. This 10-item survey was part of the Council of Academic Family Medicine Educational Research Alliance omnibus survey. Data were summarized using descriptive statistics. The survey response rate was 59% (88/148). Types of disabilities were reported for approximately 50 faculty members by 31 department chairs; only seven knew about the disability at hiring. The most common impairments were mobility, hearing, and mental health problems. Accommodations included adjusting schedules, additional time to meet tasks, and assistive technology. No additional costs were reported for accommodations by about one-third of respondents while costs were over $5,000 for approximately one-quarter. Most chairs reported that faculty performance was similar to peers without disabilities (42.2%) or adequate but not at the level of peers (40%); only one reported inadequate job performance. Faculty members with disabilities appeared to be accepted by peers, patients, learners, and staff, and only two faculty left their program because of the disability. Most chairs did not report experience with faculty members with disabilities. The disabilities encountered and accommodations were not unusual, but costs were sometimes high. While about half of chairs reported adequate or superior job performance for their faculty with disabilities, a sizeable minority judged such faculty to have poorer performance than peers despite reporting wide acceptance of faculty with disabilities by patients and colleagues. This study raises concerns about potential underreporting by faculty with disabilities and poorer

    2017-07-01

    The aim of this study was to investigate the ability of older home-care clients to perform the five times chair rise test and associated personal characteristics, nutritional status and functioning. The study sample included 267 home-care clients aged ≥75 years living in Eastern and Central Finland. The home-care clients were interviewed at home by home-care nurses, nutritionists and pharmacists. The collected data contained sociodemographic factors, functional ability (Barthel Index, IADL), cognitive functioning (MMSE), nutritional status (MNA), depressive symptoms (GDS-15), medical diagnoses and drug use. The primary outcome was the ability to perform the five times chair rise test. Fifty-one per cent ( n=135) of the home-care clients were unable to complete the five times chair rise test. Twenty-three per cent ( n=64) of the home-care clients had good chair rise capacity (≤17 seconds). In a multivariate logistic regression analysis, fewer years of education (odds ratio [OR] = 1.11, 95% confidence interval [CI] 1.04-1.18), lower ADL (OR = 1.54, 95% CI 1.34-1.78) and low MNA scores (OR = 1.12, 95% CI 1.04-1.20) and a higher number of co-morbidities (OR = 1.21, 95% CI 1.02-1.43) were associated with inability to complete the five times chair rise test. Poor functional mobility, which was associated with less education, a high number of co-morbidities and poor nutritional status, was common among older home-care clients. To maintain and to prevent further decline in functional mobility, physical training and nutritional services are needed. (NutOrMed, ClinicalTrials.gov Identifier: NCT02214758).

  19. Between Irish National Cinema and Hollywood: Neil Jordan’s Michael Collins

    Directory of Open Access Journals (Sweden)

    2007-03-01

    Full Text Available When Neil Jordan’s film Michael Collins was released in 1996, it was seen by some as a Hollywood epic, by others as a great national film. I would argue that Michael Collins combines these two traditions and occupies a space between Irish national cinema and Hollywood. The subject matter, the creative talent and the locations were Irish and the film was produced by using the Irish filmmaking infrastructure and the Irish government’s support mechanisms, but it was largely financed and distributed by a Hollywood studio. Also, to make it more appealing especially globally, but probably also locally (since Hollywood is now the international standard, it makes use of Hollywood conventions, making it accessible to international audiences as well. Despite the Hollywood mode, the fact remains that Michael Collins is a national film text, and Jordan does not make too many concessions to the non-Irish audiences.

We are studying the meaning and appropriacy of two words, ‘love’ (English and ‘любовь’ (Russian, that are the best to represent the agapelogical positive evaluation in Russian religious thought. Data for study was taken from ten different articles and extracts from books written by Fr. George Florovsky and Fr. Michael Pomazansky. On the basis of this analysis we develop semantic explications of words ‘love’ and ‘любовь’ as Christian spiritual concepts within the framework of theoretical approach of Natural Semantic Metalanguage (NSM. In summary we state that this article discusses, describes and determines some similarities and differences in understanding of concept ‘love’ in the affore-referenced works by Fr. George Florovsky and Fr. Michael Pomazansky.

Michael estudió en el colegio Nueva Granada -becado por la Texas- hasta los catorce años. En dicho colegio fue compañero de pupitre de Herbert Braun, descendiente a su vez de una familia de emigrantes a Colombia, y con quien la vida lo juntaría de nuevo en las tierras del norte y en oficios similares.

    Full Text Available St. Michaels Cathedral is one of the oldest Gothic architectural monuments in Cluj. It is built predominantly of Cenozoic (Eocene limestones which were deposited on a shallow carbonate platform. They are composed of different facies and microfacies types with varying amounts of particles, matrix and cement. Limestones from the Baci quarry (Cluj Limestone, which is situated about 3 km from the centre of Cluj, were commonly used. The weathering features correspond to the microfacies types, to the position of the stones in the walls and to the exposure (east, south, west, and north, which controls the moisture/dry cycles. This interrelationship is documented by macroscopic and microscopic examples of the decay of samples analyzed from the lower part of the walls. General parameters for a correct classification of carbonate rocks and their importance for weathering are discussed. The general mechanisms of weathering (thermal expansion, water uptake, freezing, chemical weathering are described. The migration of moisture (capillarity and the formation of crusts of varying mineralogy on the surface of building stones are documented. Macroscopic description of damage includes the decay into plates and flakes, the formation of crusts, the formation of fractures, and the growth of lichens and microorganisms. The microscopic analysis documents characteristic damage in detail: fractures parallel to the surface of the stone, internal cementation of fossil chambers (micro-nodules, repeated formation of crusts in varying generations, fracturing in intensively lithified, rigid limestones, and settling of lichens in different positions. Furthermore, different historical mortars and modern “concrete-mortars” and their behaviour in comparison to the adjacent limestones are briefly discussed. The possible conservation and restoration of weathered limestones in St. Michaels Cathedral are discussed with regard to the most recent conservation methods. The

    We described the cascade Michael.cyclization reaction of o-hydroxycinnamaldehydes with diethyl α-bromomalonate promoted by potassium carbonate. The reactions provided functionalized 2,3-dihydrobenzofurans in good yields for a variety of o-hydroxyaromatic α,β-unsaturated aldehydes. Current work focuses on expanding the scope of this reaction to other substrates such as sulfur yields, and on developing an efficient catalytic asymmetric variant. 2,3-Dihydrobenzofurans are found in numerous biologically active natural products and synthetic compounds. These are an attractive type of oxygenated compound because their basic core skeleton is present in neolignans, pterocarpans, and synthetic drugs used in the treatment of pulmonary hypertension, atherosclerotic peripheral arterial disease, and central nervous system trauma and ischemia. Owing to the importance of their structures, numerous synthetic methods for 2,3-dihydrobenzofurans have been developed, primarily: radical cyclizations, Lewis acid promoted reactions, anionic cyclizations, and transition-metal catalyzed processes. However, these methods cannot be generalized as much as is desirable, and they yielded poor chemo- and/or stereoselectivities. Hence, the development of an efficient enantioselective synthetic method for obtaining 2,3-dihydrobenzofuran scaffolds attracted our attention.

    2012-07-01

    The growing appreciation of the need to adopt an evidence-based approach to teaching and assessment has led to a demand for faculty who are well versed in best practices in education. Surgeons with interest and expertise in instruction, curriculum development, educational research, and evaluation can have an important impact on the educational mission of a department of surgery. The increased fervor for accountability in education together with the challenges imposed by accreditation agencies and hospitals has made educational leadership responsibilities more time consuming and complex. In response to this, an increasing number of department chairs created Vice Chair for Education positions to support clerkship and program directors and ensure the department's education mission statement is fulfilled.

    2007-07-01

    The objective of this study was to quantitatively determine, at chair side, the serum C-reactive protein (CRP) levels in dental emergency patients. Quantitative CRP test was performed at chair side in 40 patients with acute alveolar abscess (AAA), acute periodontal abscess (APA), and alveolar osteitis (AO) at the time of dental emergency treatment and 1 week after. CRP levels were compared between groups and before and after treatments using ANOVA and Fisher's Exact tests. Serum CRP levels were greater than 5 mg/L in 30 (75%) of the 40 patients. At 1-week follow-up, the decline in CRP levels was evident in the AAA group (P .05). Serum CRP levels are often elevated in patients with odontogenic infections and postoperative complications. Rapid reduction in serum CRP levels was likely to occur following successful treatment of AAA, but less likely to occur in APA and AO.

    The inauguration of the prospective modeling chair in favour of sustainable development is the result of the joint effort of several schools, organizations and companies, in particular: Mines ParisTech, Ponts ParisTech, Agro ParisTech, the higher education and research pole of ParisTech, the Ecole des Ponts foundation, the mineral, mining and metallurgic industries foundation (FI3M), with the partnership of Ademe, EdF, Renault, Schneider Electric and Total. The main goal of this chair is to perpetuate modeling tools with sustainable development stakes. The scientific program and the expertise of this chair are based on the joint and complementary experience of its two co-founder research teams in the domain of long-term prospective of energy, economy and environment-related questions: the applied mathematics centre (CMA - Mines ParisTech) and the international centre of environment and sustainable development research (CIRED). An inaugural colloquium was organized at the occasion of the launching of this chair. During round tables, representatives of the different intervening parties explained the stakes of this huge project and their expectations, in particular from the scientific, economical and societal point of view. A workshop on the topic 'carbon and prospective' followed the round tables. Six presentations were given about the following topics: energy policy scenarios for 2050 (Moncomble, J.E.), the shadow price of carbon (Chambolle T.), mitigation targets and carbon values: insights from TIMES-FR (Assoumou E.), climate protection and infrastructures (Sassi O.), China's energy and carbon options (Wenying C.), EU 20-20 policy implications on the energy system of Germany - an analysis with TIMES PanEU (Blesl M.). This book gathers the proceedings of both parts of this colloquium, the debates during the round tables (in French) and the presentations given during the workshop (in English). (J.S.)

    Gait speed, maximum grip strength and thirty seconds chair stand test are quick, reliable measures of functional capacity in older adults. The objective of this study was to develop normative data of the said parameters, which is lacking in older Indians. In a cross sectional study, 723 participants of ≥60 years without any morbidity, were recruited with written consent at Geriatric Medicine clinic of All India Institute of Medical sciences, New Delhi. Time taken to walk comfortably (4m) was taken as Gait speed. Maximum grip strength was assessed by using dynamometer by pressing it for 3 times in each hand, and the best of six values noted. Thirty second chair stand was assessed by the number of repetitions to stand and sit from a chair in thirty second. The Cut-off (25th percentile) of gait speed for both male and female in all age group was 0.6m/s. The Cut-off for maximum grip strength in 60-65 years, 66-70 years and >70 years for male were 20, 15 and 15 and for females were 8, 6 and 6 in kg, respectively. The Cut-off for thirty second chair stand test in 60-65 years, 66-70 years and >70 years for male were 10, 9 and 8 and for females was 8, 8 and 7, respectively. These normative data would be useful to the clinicians and researcher as Indian reference value, which is less as compared to western data. Community based multi-centre study is needed.

    Unstable sitting on a wobble chair with different balance difficulty levels can be used as an effective tool in exercises as well as evaluation and therapeutic stages of rehabilitation. No data on muscle activity levels and spinal loads are however available to assess its safety compared to other regular daily activities. The goal of this study was to estimate muscle forces and spinal loads in a seated unstable wobble chair task. In vivo 3D kinematics of the trunk and seat collected in an earlier study were used here to drive computational trunk musculoskeletal models of 6 normal and 6 low-back pain subject groups sitting on a wobble chair for a duration of 10s. Results revealed no significant differences between kinematics, muscle forces, spinal loads and force plate reaction forces when comparing these two groups. The estimated muscle forces and spinal loads were moderate though larger than those in a stationary sitting posture. Local spinal forces at the L5-S1 disc varied with time and reached their peaks (1473 N and 1720 N in compression, 691 N and 687 N in posterior-anterior shear and 153 N and 208 N in right-left shear, respectively for healthy and CLBP groups) being much greater relative to those in the stationary sitting posture (means of 12 subjects: 768 N, 284 N and 0 N, respectively). The wobble chair with characteristics considered in this study is found hence safe enough as a therapeutic exercise for both healthy and low-back pain subjects. Copyright © 2016 Elsevier Ltd.

    There is no more important decision an academic Plastic Surgery Department or Division can make than naming a chair or chief. Externally recruited leadership brings fresh perspectives and connections. Critics, however, argue that they lack the in-depth knowledge of the institution's culture and history that may be needed to succeed. The ability and skill of an internal candidate is already known and can increase the odds of that person's success in the leadership position. Finally, external recruitment can be a more costly process. Ultimately, the decision is really a litmus test for a Plastic Surgery program. The authors aim to evaluate factors influencing ascent in Plastic Surgery leadership, including training history, internal promotion, and external recruiting. All Plastic Surgery residency programs accredited by the Accreditation Council for Graduate Medical Education were noted (n = 71). Academic departmental chairs or divisional chiefs of these residency programs were identified at the time of study design (October 1, 2011). For each chair or chief, gender, training history, and faculty appointment immediately prior to the current leadership position was recorded. There were 71 academic chairs or chiefs of Plastic Surgery residency programs at the time of data collection. The majority (62%) had done fellowship training following Plastic Surgery residency. Fellowships included hand (43%), craniofacial (29%), microsurgery (18%), and other types (10%). The majority (73%) of leaders were internal hires (P promotion. However, only a fraction (22%) of these internal hires had done Plastic Surgery residency or fellowship training at that institution (P promotion, but always with an eye towards the advantages of bringing in external talent as a valuable contribution to increase organizational success.

    People working at computers often suffer from overload-related muscle pain, and physical and mental discomfort. The aim of the study was to evaluate the effectiveness of chair massage, conducted in the workplace among white-collar workers, in relieving symptoms of musculoskeletal strain related to prolonged sitting posture. The study was conducted in 124 white-collar workers, 55 women and 69 men, aged 33.7 ± 7.6 years. Subjects were randomly assigned to three groups: chair massage program, relaxing music sessions, and a control group, each of four-week duration. Each group was evaluated before and after the program completion. Pain perception was assessed algometrically as a threshold for compression pain of neck muscles, measured in kg/cm 2 . The relaxation level was assessed from the heart rate variability. We found that the chair massage increased both the pain threshold in all tested muscles (p pain threshold remained unchanged, except for the trapezoid muscle where it decreased (p occupational environments.

    Physically handicapped people due to accidents for example have been increasing yearly in number with the increase of the aged, spread of cars, and change in the living environment. Therefore, participation in society by such people as called the weak is indispensable. Under the circumstances, as a means of their participation, a wheel chair as a moving aid was examined from the viewpoint of medical treatment and classified into three categories as follows: (1) for the use of the aged who are healthy but leg muscles are weak, (2) for the use of the invalid incapable of moving a part of the body and (3) for the use in sports by people who are disabled in the lower half of the body but healthy otherwise. In other words, prototypes were made for three kinds of solar wheel chair, for the aged, for the invalid and for sport use by the disabled, with a field test performed for each prototype. The wheel chairs were exhibited in the school, used in welfare facilities and driven by a disabled person who participated in 100km marathon. The users` opinions were favorable stating they were able to drive by themselves the new vehicle utilizing the clean energy and to move around by their own free will. 6 refs., 5 figs.

    Increasing numbers of people spend the majority of their working lives seated in an office chair. Musculoskeletal disorders, in particular low back pain, resulting from prolonged static sitting are ubiquitous, but regularly changing sitting position throughout the day is thought to reduce back problems. Nearly all currently available office chairs offer the possibility to alter the backrest reclination angles, but the influence of changing seating positions on the spinal column remains unknown. In an attempt to better understand the potential to adjust or correct spine posture using adjustable seating, five healthy subjects were analysed in an upright and reclined sitting position conducted in an open, upright MRI scanner. The shape of the spine, as described using the vertebral bodies' coordinates, wedge angles, and curvature angles, showed high inter-subject variability between the two seating positions. The mean lumbar, thoracic, and cervical curvature angles were 29 ± 15°, -29 ± 4°, and 13 ± 8° for the upright and 33 ± 12°, -31 ± 7°, and 7 ± 7° for the reclined sitting positions. Thus, a wide range of seating adaptation is possible through modification of chair posture, and dynamic seating options may therefore provide a key feature in reducing or even preventing back pain caused by prolonged static sitting.

    To determine the effects of the relative inactivity and unloading on the strength of the tibias of monkeys, Macaca mulatta, we used a non-invasive test to measure bending stiffness, or EI (Nm2), a mechanical property. The technique was validated by comparisons of in vivo measurements with standard measures of EI in the same bones post-mortem (r2 = 0.95, P monkeys, 3.0+/-0.7 years and 3.6+/-0.6 kg, revealed EI to be 16% higher in the right than left tibia (4.4+/-1.6 vs. 3.7+/-1.6 Nm2, P monkeys, restrained in chairs for 14 days, showed decreases in EI. There were no changes in EI in two chaired monkeys that lost weight during a 2-week space flight. The factors that account for both the decreases in bone mechanical properties after chair restraint at 1 g and lack of change after microgravity remain to be identified. Metabolic factors associated with body weight changes are suggested by our results.

    To identify the benefits and consequences of having part-time faculty members in departments of pharmacy practice from the department chair's perspective. A stratified purposive sample of 12 pharmacy practice department chairs was selected. Eleven telephone interviews were conducted. Two investigators independently read interview notes and categorized and enumerated responses to determine major themes using content analysis. The investigators jointly reviewed the data and came to consensus on major themes. Benefits of allowing full-time faculty members to reduce their position to part-time included faculty retention and improved individual faculty work/life balance. Consequences of allowing part-time faculty positions included the challenges of managing individual and departmental workloads, the risk of marginalizing part-time faculty members, and the challenges of promotion and tenure issues. All requests to switch to part-time status were faculty-driven and most were approved. There are a variety of benefits and consequences of having part-time faculty in pharmacy practice departments from the chair's perspective. Clear faculty and departmental expectations of part-time faculty members need to be established to ensure optimal success of this working arrangement.

    Full Text Available In June 2007, I had the privilege of attending a Healing of Memories workshop lead by Father Michael Lapsley, one of the founder members of the Institute for Healing of Memories. The purpose of the workshop was to help the predominantly white members of a middle class Dutch Reformed congregation in the Northern Suburbs of Cape Town and the predominantly coloured members of a congregation of the Evangelical Lutheran Church in Elsies River on the Cape Flats, to share their stories of the past with regard to apartheid with each other. Apart from the stories that were told and the sharing of experiences about the apartheid history that took place, I was struck by the way in which Father Lapsley conducted the workshop. There was a deep compassion for all the participants as was embodied through the way in which he treated each of us with respect. But apart from his cordiality in leading the workshop, one could sense a deeper source of compassion, a source revealing a compassionate understanding of God�s presence amidst the violence and turmoil in our broken world. The aim of this article is to reflect on whether one could speak of something like �compassionate leadership�, and to take a closer look at the relationship between compassion and God images in the life and work of Michael Lapsley. Special attention will be given to the way in which he exercises leadership through his many involvements related to his own personal story of trauma.Intradisciplinary and/or interdisciplinary implications: This article presents literary research on the notion of compassionate leadership as a specific kind of leadership. The results indicate that the leadership of Father Michael Lapsley does indeed portray features of this kind of leadership. The research can become the source for finding new strategies for religious leadership.

    Full Text Available The Great War has featured regularly in Michael Longley’s poetry, for personal, family, aesthetic and political reasons. His collection published in 2011 under the title A Hundred Doors contains a number of poems relating to his father and the so-called War Poets, in connection with others in which love and nature, life and death are also dominant themes. This article will show how, as elsewhere in his poetry, everything is interrelated, “the nature poetry”, in Longley’s words, “fertilizing the war poetry”.

    Michael Servetus was the first doctor ever to challenge and scientifically argue against the theories of Galen, which predominated for 14 centuries in medical schools worldwide. Even though he was relatively correct in scientific terms, Servetus was punished because of his boldness in challenging Galen's theories and was condemned to death by the Holy Inquisition. Yet, by publicly challenging Galen's and Hippocrates' predominant and unquestionable lessons on medicine for the first time, Servetus opened the door for other doctors to challenge and correct those theories and subsequently to bring about a new view of human anatomy and physiology. This article underlines the contribution of Servetus to the description of the pulmonary circulation.

  12. POLYETHYLENEIMINE (PEI ON SILICA AS CATALYST IN KNOEVENAGEL AND MICHAEL REACTIONS

    Full Text Available After the synthesis of polyethylenimine supported on silica, it has been used as a new and efficient catalyst in Knoevenagel and Michael condensations. The presence of the polyethylenimine in the catalytic system together with silica displays an acido-basic character allows a better catalytic activity in the condensations. Carried out under microwave irradiation, without organic solvent and during short time, the syntheses are respectful towards green chemistry. The solid catalyst can be easily reused. This catalyst has the acido-basic character at the same time.

    Biographers of Michael Faraday, as well as many dictionaries of science, often describe him as a physicist, which he certainly was. But he was also an astonishingly effective chemist: in fact, he was the Fullerian Professor of Chemistry (at the Royal Institution, RI) from 1834 until the time of his death in August, 1867. To mark the sesquicentenary of his passing, this editorial, by one of his distant successors as Director and Fullerian Professor at the RI, focuses on Faraday's output and influence as a scientist.

    EOS imaging (EOS System; EOS imaging, Paris, France) enables fast 2-D/3-D imaging of children in standing load-bearing position. Non-ambulatory children with neuromuscular scoliosis need evaluation of their spinal balance while in a normal daily position. We designed a customized chair fitting the EOS patient-area dimensions to obtain images in natural sitting postures. The chair is a 360 rotating orthopaedic chair made of fully radiolucent polyethylene and equipped with an adjustable headrest and three-point belts. Out of 41 consecutive patients, 36 (88%, 95% confidence interval 74-96%) had successful imaging. In most patients with severe neuromuscular trunk deformities, the EOS system combined with our chair was useful for assessing preoperative trunk collapse, pelvic obliquity and postoperative corrections in all planes. This specific device changed our daily practice for the assessment of spinal deformities in non-ambulatory patients. (orig.)

    2017-10-01

    The purpose of this study was to determine which office chair feature is better at improving spine posture in sitting. Participants (n = 28) were radiographed in standing, maximum flexion and seated in four chair conditions: control, lumbar support, seat pan tilt and backrest with scapular relief. Measures of lumbar lordosis, intervertebral joint angles and sacral tilt were compared between conditions and sex. Sitting consisted of approximately 70% of maximum range of spine flexion. No differences in lumbar flexion were found between the chair features or control. Significantly more anterior pelvic rotation was found with the lumbar support (p = 0.0028) and seat pan tilt (p chair features used, still involves near end range flexion of the spine. This will increase stresses to the spine and could be a potential injury generator during prolonged seated exposures.

    2015-06-01

    Full Text Available Background: Classroom behaviorsare disturbed in autistic students because of their repetitive, restlessness, and disruptive behaviors. This study aimed to examine the impacts of sitting on a ball, cushion, and/or common chair on classroom behavior of four students with Autism Spectrum Disorder (ASD. Methods: Four children with Autism participated in this single-subject study. Students’ behaviors were video recorded in three phases: Sitting on their common chairs during phase A, air-sit cushioned in phase B, and ball chairs in phase C. Sitting times and on-task/off-task behaviors were quantified by momentary time sampling (every 10 seconds and compared during different phases for important changes. Social validity was taken by the teacher at the end of the research as well. Results: The findings demonstrated increases in on-task and in-seat behaviors in four students when seated on air sit cushioned chairs. Despite rises of ontask behaviors for all students, only two of the students showed enhanced inseat behaviors when seated on therapy balls. Social validity findings indicated that the teacher preferred the use of the balls and air-cushioned chairs for her students. Conclusion: Therapy balls/cushioned chairs for students with ASD may facilitate in-seat and on-task behavior.

    Muscle atrophy and weakness impair activity of daily living (ADL). We examined whether chair stand exercise can improve ADL of hemodialysis patients. A randomized controlled trial. A single center study. Outpatients on hemodialysis older than 60 years (61-79 years). Twelve weeks of intervention with chair stand exercise, 3 sessions/week versus the control exercise (stretch, 1 session/week). The primary outcome was the change in functional independence measure (FIM) score from baseline. The secondary outcomes were changes in thigh circumference, muscle strength of quadriceps, 6-minute walking distance, maximum duration of chair stand exercise, health-related quality of life, cognitive function serum albumin, and hemoglobin. Among the 27 patients who were randomized, 17 completed the study. The change in FIM from baseline was greater in the intervention group (1 [1-3] vs. 0 [0-0], median (minimum to maximum), P chair/wheel chair) and locomotion (stair). Among the secondary outcomes, significant difference was noticed in the changes in thigh circumference and the physical component summary score of health-related quality of life by Medical Outcome Study 36-Item Short-Form Health Survey (SF-36v2). Chair stand exercise improved ADL in the hemodialysis patients aged older than 60 years. Copyright © 2015 National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

    We report, for what we believe is the first time, generation of stable chair-like pulses (a pulse shape with an initial long flat portion followed by a short high peak power portion resembling the shape of a chair) by mode locking of a Ytterbium (Yb)-doped fiber laser. Chair-like pulse shapes are achieved by implementing dual saturable absorbers, one based on a nonlinear optical loop mirror (NOLM) and the other based on nonlinear polarization rotation (NPR) inside the cavity. The transmission characteristics of the NOLM-NPR pair leading to the formation of chair-like pulses are numerically investigated. We also report the amplification characteristics of chair-like pulses in an external multistage Yb-doped fiber amplifier setup at different repetition rates of the pulse train. It was found that the chair-like pulses are suitable for amplification, and more than 10 W of average power at 460 kHz repetition rate have been obtained at total pump power of ∼20  W coupled to the power amplifier. At a lower repetition rate (115 kHz), ∼8  W of average power were obtained corresponding to ∼70  μJ of pulse energy with negligible contribution from amplified spontaneous emission or stimulated Raman scattering. We believe that such an oscillator-amplifier system could serve as an attractive tool for micromachining applications.

  3. The description of the litigious querulant: Heinrich von Kleist's Novella Michael Kohlhaas.

    To illustrate the use of fiction in understanding psychiatric disorders and refocus attention towards fiction as a valuable source of psychopathology, thereby contributing to the restoration of the narrative in psychiatry. A psychopathological analysis of the novella Michael Kohlhaas written by Heinrich von Kleist, one of the outstanding literary figures of the German romantic movement of the early 19th century. The protagonist of Kleist's novella, Michael Kohlhaas, a querulant horse trader, carries out an armed uprising disproportionate to the minor injustice of the unlawful seizure of his horses. Following unsuccessful attempts at legal recourse, Kohlhaas takes up arms against the authorities, and in the course of his uncompromising pursuit of justice eventually sacrifices his own and his family's lives. Kleist accurately portrays Kohlhaas' psychopathological development from a psychologically balanced, emotionally warm family man to one who causes utter destruction, mayhem and the loss of innocent lives. This literary work is a remarkably authentic, insightful and rich representation of litigious/querulant behaviour, described by classical authors as litigious paranoia, a diagnostic category currently subsumed under 'delusional disorder, persecutory type', in DSM-5 and 'persistent delusional disorder' in ICD-10. Kleist's novella offers important clues to better understand the development of litigious-querulant behaviour and the inner world of its sufferers. An analysis of the novella also illustrates the contribution that fiction could make to resuscitate the narrative as a complement to criterion-based diagnostic practice prevailing in contemporary psychiatry. © 2014 S.

  4. Michael Polanyi and his generation origins of the social construction of science

    CERN Document Server

    Nye, Mary Jo

    2011-01-01

    In Michael Polanyi and His Generation, Mary Jo Nye investigates the role that Michael Polanyi and several of his contemporaries played in the emergence of the social turn in the philosophy of science. This turn involved seeing science as a socially based enterprise that does not rely on empiricism and reason alone but on social communities, behavioral norms, and personal commitments. Nye argues that the roots of the social turn are to be found in the scientific culture and political events of Europe in the 1930s, when scientific intellectuals struggled to defend the universal status of scientific knowledge and to justify public support for science in an era of economic catastrophe, Stalinism and Fascism, and increased demands for applications of science to industry and social welfare. At the center of this struggle was Polanyi, who Nye contends was one of the first advocates of this new conception of science. Nye reconstructs Polanyi’s scientific and political milieus in Budapest, Berlin, and Manchester f...

  5. Traces of the Unrepresentable in the Modernist Discourse of Clement Greenberg and Michael Fried

    Directory of Open Access Journals (Sweden)

    Gal, Nissim

    2013-08-01

    Full Text Available The present essay aims to remap the modernist writing of Clement Greenberg and his successor Michael Fried from the late 1930s to the 1960s. For many years these two critics/theorists were considered leaders of the American modernist camp that promoted the purity of the medium and the total dependence of reading art on the primacy of perception. Attentive reading of the canonical texts they authored will surprisingly reveal that between the theoretical lines of their writings dwells an essential element that contradicts the absolute dominance of eyesight. Lying at the heart of the Greenbergian act is a metaphysical foundation that poses the question of the invisible as part of the inquiry into the "essence of the visible". As such the modernist debate will be revealed not only as a means for assembling a canon of works, but also as a means to formulating an experience of revelation in terms of the visual. Attentive reading of the writings of Clement Greenberg and the early Michael Fried, reveals a theoretical element or regulative idea that will be termed here "the unrepresentable".

    CAD/CAM (computer-aided design and computer-aided manufacturing) systems have refreshed the idea of chair-side production of restorations, but the fracture of ceramic veneers remains a problem. Cementation with glass fibers may improve the fracture strengths and affect the failure modes of CAD/CAM-generated ceramic veneers. Therefore, this study compared the fracture strengths of ceramic veneers produced at chair side and cemented with or without glass fibers with those of composite veneers. Thirty intact mandibular incisors were randomly divided into three groups ( n = 10) and treated with CAD/CAM-fabricated veneers cemented with dual-cure composite resin luting cement (CRLC; Group 1), CAD/CAM-fabricated veneers cemented with a glass fiber network (GFN) and dual-cure CRLC (Group 2), and a direct particulate filler composite veneer constructed utilizing fiber and a restorative composite resin (Group 3). The specimens were tested with a universal testing machine after thermal cycling treatment. The loads at the start of fracture were the lowest for traditionally fabricated composite veneers and higher for CAD/CAM-generated. Veneers cemented either without or with the GFN. The failure initiation loads (N) for the veneers were 798.92 for Group 1, 836.27 for Group 2, and 585.93 for Group 3. The predominant failure mode is adhesive failure between the laminates and teeth for Group 1, cohesive failure in the luting layer for Group 2, and cohesive laminate failure for Group 3, which showed chipping and small fractures. Ceramic material is a reliable alternative for veneer construction at chair side. Fibers at the cementation interface may improve the clinical longevity and provide higher fracture strength values.

    Self-criticism plays a key role in many psychological disorders and predicts poor outcome in psychotherapy. Yet, psychotherapy research directly targeting self-critical processes is limited. In this pilot study, we examined the efficacy of an emotion-focused intervention, the two-chair dialogue task, on self-criticism, self-compassion and the ability to self-reassure in times of stress, as well as on depressive and anxiety symptoms among nine self-critical clients. Results showed that the intervention was associated with significant increases in self-compassion and self-reassuring, and significant reductions in self-criticism, depressive symptoms and anxiety symptoms. Effect sizes were medium to large, with most clients exhibiting low and non-clinical levels of symptomatology at the end of therapy, and maintaining gains over a 6-month follow-up period. Although preliminary, these finding suggest that emotion-focused chair work might be a promising intervention addressing self-criticism. Self-criticism is an important process in a variety of clinical disorders and predicts poor outcome in brief therapy for depression. Yet, little is known about how self-criticism can be effectively addressed in psychological treatment. Practitioners can benefit from increasing their awareness of self-critical processes in their clinical work, and from directly working with emotions in addressing self-criticisim. Emotion-focused two-chair dialogue intervention can be effective in reducing self-criticism, increasing self-compassion, and decreasing depressive and anxiety symptoms, and these improvements are largely maintained six months after therapy.

    The aim of the study were to demonstrate the possible hemodynamic changes and cerebral blood flow alterations in patients who were positioned from supine to beach chair position; and to detect if the position change causes any cortical activity alteration as measured by the 4-channeled electroencephalography monitor. 35 patients were included. Before the induction, mean arterial pressure and patient state index values were recorded (T0). After the intubation, doppler-ultrasonography of the patients' internal carotid and vertebral arteries were evaluated to acquire cerebral blood flow values from the formula. In supine position, mean arterial pressure, patient state index and cerebral blood flow values were recorded (T1) and the patient was positioned to beach chair position. After 5min all measurements were repeated (T2). Measurements of patient state index and mean arterial pressure were repeated after 20 (T3), and 40 (T4)min. There was a significant decrease between T0 and T1 in heart rate (80.5±11.6 vs. 75.9±14.4beats/min), MAP (105.8±21.9 vs. 78.9±18.4mmHg) and PSI (88.5±8.3 vs. 30.3±9.7) (all pchair position. Beach chair position was associated with a decrease in cerebral blood flow and patient state index values. Patient state index was affected by the gravitational change of the cerebral blood flow; however, both factors were not directly correlated to each other. Moreover, the decrease in patient state index value was transient and returned to normal values within 20min. Copyright © 2015 Sociedade Brasileira de Anestesiologia.

    2017-07-01

    The objective of this prospective clinical study was to evaluate the clinical performance of chair-side generated monolithic lithium disilicate crowns after 72 months. Forty-one posterior full contour crowns made of lithium disilicate ceramic were inserted in 34 patients with a chair-side CAD/CAM technique. One crown per patient was randomly selected for evaluation at baseline, 6, 12, 24, 36, 48, 60 and 72 months according to the modified US Public Health Service criteria. After a mean examination time of 73.2 months (SD ± 1.7 months), 25 crowns were available for re-examination. Within the observation period, three failures occurred due to one crown fracture after 2.9 years, an abutment fracture after 6.0 years, and one severe endodontic problem after 6.1 years. One lithium disilicate crown showed a loss of retention after 2 years but could be reinserted. There were two events of caries below the crown margin, one after 24 and another one after 48 months. Both teeth received cervical adhesive composite fillings. Two abutment teeth changed their sensibility perception from positive to negative within the first 13 months. The failure-free rate was 87.6%, and the complication-free rate was 70.1% after 6 years according to the Kaplan-Meier analysis. Due to the fact that there was only one severe technical complication and the severe biological complications were in a normal range, the clinical performance of monolithic lithium disilicate crowns in the posterior region was completely satisfying. The chair-side application of monolithic lithium disilicate crowns can be recommended.

  11. Utilizing Chair Massage to Address One Woman's Health in Rural Ghana West Africa: a Case Report.

    2016-12-01

    There is limited access to health care in rural Ghana and virtually no rehabilitative services available. This situation presents a unique opportunity to utilize chair massage in addressing women's health in rural Ghana, particularly when it comes to muscle pain and fatigue from heavy labor. The objective of this case report is to determine the results of chair massage as a strategy to reduce neck, shoulder, and back pain, while increasing range of motion. The patient is a 63-year-old Ghanaian female, who was struck by a public transport van while carrying a 30-50 pound load on her head, two years prior. The accident resulted in a broken right humerus and soft tissue pain. A traditional medicine practitioner set the bone, however there was no post-accident rehabilitation available. At the time of referral, she presented complaints of shoulder, elbow, and wrist pain. In addition, she was unable to raise her right hand to her mouth for food intake. The results of this case report include an increase in range of motion, as well as elimination of pain in the right shoulder, elbow, and hand. Visual assessments showed an approximate increase of ROM within the ranges of 45-65 degrees in the right arm, as well as 10-15 degrees in 4th and 5th fingers. There was also a decrease in muscle hypertonicity in the thoracic and cervical areas, and a profound increase in quality of life for the patient. This case report illustrates how therapeutic chair massage was utilized to address a common health concern for one woman in rural Ghana. It also demonstrates that pre-existing musculoskeletal disorders and pain may be eliminated with massage intervention. Massage therapy may be important to ameliorating certain types of health problems in remote rural villages in low income countries.

    The aim of the study was to check four lab-side and four chair-side methods for finishing and polishing the ceromer material Targis. Eighty bar-shaped specimens (20 mm x 10 mm x 2 mm) of Vectris were produced; 72 were covered with a 2 mm (thickness) layer of the Ceromer Targis and eight samples with the composite Tetric. All specimens were ground plane parallel with 320 Silicium carbide grit sandpaper in order to start with the same level of roughness. Then the specimens were finished and polished using the following methods: (1) Artglass toolkit, (2) pumice-stone and brushes/linen brush and polishing paste P3, (3) Robinson brush/Ivoclar Universal paste and wool brush, (4) Silicone wheel and rag wheel, (5) Shofu Rainbow set, (6) Sof-Lex discs, (7) Vivadent Politip set and (8) Nupro-pastes and brushes. The surface roughness was determined with a profilometer. The arithmetical roughness value Ra was calculated. From each group one specimen was randomly chosen and sputtered with gold in order to observe the surface with a scanning electron microscope to evaluate its smoothness. The methods were ranked as followed: 2, 3 and 5 with the lowest roughness, then 8, 6, 7, 4, 1. The best ranked chair-side method (5) and the best ranked lab-side methods (2, 3) did not differ significantly between the Ra values. No difference was observed between the composite Tetric and the ceromer Targis when these materials were polished using the same method. the lab-side-methods 2 and 3 and the chair-side-method 5 can be recommended for finishing and polishing the new ceromer material Targis.

    Michael addition polymerizations of amines and acrylic monomers are versatile approaches to biomaterials for various applications. A combinatorial library of poly(β-amino ester)s and diverse poly(amido amine)s from diamines and diacrylates or bis(acrylamide)s have been reported, respectively. Furthermore, novel linear and hyperbranched polymers from Michael addition polymerizations of trifunctional amines and acrylic monomers significantly enrich this category of biomaterials. In this Review, we focus on the biomaterials from Michael addition polymerizations of trifunctional amines and acrylic monomers. First we discuss how the polymerization mechanisms, which are determined by the reactivity sequence of the three types of amines of trifunctional amines, i.e., secondary (2°) amines (original), primary (1°) amines, and 2° amines (formed), are affected by the chemistry of monomers, reaction temperature, and solvent. Then we update how to design and synthesize linear and hyperbranched polymers based on the understanding of polymerization mechanisms. Linear polymers containing 2° amines in the backbones can be obtained from polymerizations of diacrylates or bis(acrylamide)s with equimolar trifunctional amine, and several approaches, e.g., 2A 2 +BB'B″, A 3 +2BB'B', A 2 +BB'B″, to hyperbranched polymers are developed. Further through molecular design of monomers, conjugation of functional species to 2° amines in the backbones of linear polymers and the abundant terminal groups of hyperbranched polymers, the amphiphilicity of polymers can be adjusted, and additional stimuli, e.g., thermal, redox, reactive oxidation species (ROS), and light, responses can be integrated with the intrinsic pH response. Finally we discuss the applications of the polymers for gene/drug delivery and bioimaging through exploring their self-assemblies in various motifs, e.g., micelles, polyplexes particles/nanorings and hydrogels. Redox-responsive hyperbranched polymers can display 300

    Chair-sitting may allow for more readily activated scalene, sternocleidomastoid, and parasternal intercostal muscles, and may raise and enlarge the upper thoracic cage, thereby allowing the thoracic cage to be more easily compressed. To evaluate the effect of chair-sitting during exercise training on respiratory muscle function in mechanically ventilated patients. We randomized 16 patients to a control group and 18 patients to a chair-sitting group. The patients in the chair-sitting group were transferred by 2 intensive care unit nurses from bed to armchair and rested for at least 30 min, based on the individual patient's tolerance. We measured heart rate, blood pressure, S(pO(2)), and respiratory rate. In the treatment group, before transferring the patient from bed to armchair, and 30 min after the completion of chair-sitting we measured respiratory muscle function variables, including the ratio of respiratory rate (f) to tidal volume (V(T)), S(pO(2)), maximum inspiratory pressure (P(Imax)) and maximum expiratory pressure (P(Emax)). In the control patients we took those same measurements while the patient was in semirecumbent position, before and after treatments, for at least 6 days or until the patient was discharged from the intensive care unit or died. The 2 groups did not significantly differ in age, sex, or clinical outcomes. Respiratory rate, V(T), f/V(T), S(pO(2)), P(Imax), and P(Emax) were not significantly better in the chair-sitting group. The study period significantly improved respiratory rate, V(T), P(Imax), and P(Emax) (all P chair-sitting exercise training did not significantly improve respiratory muscle function in mechanically ventilated patients.

    Full Text Available Readily available chiral ammonium salts derived from cinchona alkaloids have proven to be effective phase transfer catalysts in the asymmetric Michael reaction of 3-substituted isoindolinones. This protocol provides a convenient method for the construction of valuable asymmetric 3,3-disubstituted isoindolinones in high yields and  moderate to good enantioselectivity. Diastereoselectivity was also investigated in the construction of contiguous tertiary and quaternary stereocenters. The use of acrolein as Michael acceptor led to an interesting tricyclic derivative, a pyrroloisoindolinone analogue, via a tandem conjugated addition/cyclization reaction.

    2015-11-16

    An efficient N-heterocyclic carbene (NHC)-catalysed vinylogous Michael addition of deconjugated butenolides was developed. In the presence of 5 mol% of the NHC catalyst, both γ-alkyl and aryl-substituted deconjugated butenolides undergo vinylogous Michael addition with various α, β-unsaturated ketones, esters, or nitriles to afford γ,γ-disubstituted butenolides containing adjacent quaternary and tertiary carbon centers in good to excellent yields with excellent diastereoselectivities. In this process, the free carbene is assumed to act as a strong Brønsted base to promote the conjugate addition.

    A new catalytic asymmetric desymmetrization reaction for the synthesis of enantioenriched derivatives of 2-azabicyclo[3.3.1]nonane, a key motif common to many alkaloids, has been developed. Employing a cyclohexanediamine-derived primary amine organocatalyst, a range of prochiral cyclohexanone derivatives possessing an α,β-unsaturated ester moiety linked to the 4-position afforded the bicyclic products, which possess three stereogenic centers, as single diastereoisomers in high enantioselectivity (83-99% ee) and in good yields (60-90%). Calculations revealed that stepwise C-C bond formation and proton transfer via a chair-shaped transition state dictate the exclusive endo selectivity and enabled the development of a highly enantioselective primary amine catalyst. © 2015 WILEY-VCH Verlag GmbH & Co.

    A series of heterogeneous catalysts for asymmetric Michael additions was synthesized based on ephedrine chemically bound to the surface of silica. The length of the hydrocarbon chain binding the active center to the support surface affects the sign of rotation of the reaction product from the asymmetric addition of thiophenol to benzylideneacetophenone. Grafting ephedrine to the silica surface via a short hydrocarbon chain results in a change in the configuration of the reaction product. Silanol groups on the silica surface are involved in the transition state, as evidenced by data obtained using silica which has been exhaustively treated with trimethylchlorosilane. The absolute specific rotation of 1,3-diphenyl-3-thiophenylpropan-1-one has been established.

Humanist observers of painting in Italy and the discovery of pictorial composition of 1971. It includes reflections on the book’s reorientations of the scholarly debate over the relationship between Renaissance/Early Modern humanism and painting, as well as consideration of the linguistic theories that either directly or tangentially inform Baxandall’s method. Sources such as Wittgenstein, Cassirer, Ordinary Language Philosophy, and the Sapir-Whorf Hypothesis are discussed. Some of the book’s aims and methods are clarified by a comparison to Panofsky’s Gothic Architecture and Scholasticism of 1951.

    2016-04-01

    Full Text Available The paper treats the relationship between the art historian Michael Fried and the philosopher Stanley Cavell, as well as their readings of Wittgenstein’s late philosophy. It argues that Fried’s entire historic-artistic method rests on Wittgensteinian grounds; there is special emphasis on theses concerning the grammatical criteria of language and scepticism. Namely, Fried, like Cavell, interprets modernism as a crisis of a priori criteria by which we come to think a given object as a successful work of art. Fried labels an artwork’s failure to convince, to communicate with the recipient, with the term theatre. This text establishes an analogy between Fried’s concept of theatre, Cavell’s concept of scepticism, and Wittgenstein’s thesis of the impossibility of a private language, situating those theses in the wider context of discussions of modernism.

    2016-10-01

    This new book from Michael Hauskeller explores the currently marketed or projected sex/love products that exhibit some trait of so-called "posthumanistic" theory or design. These products are so designated because of their intention to fuse high technologies, including robotics and computing, with the human user. The author offers several arguments for why the theory behind these products leads to inconsistencies. The book uses a unique approach to philosophical argument by enmeshing the argument's major points in a concomitant discussion of pieces from world literature pertaining to posthumanism. The method is compelling, heightened by great world authorial insights that rarely find their way into philosophy and shores up some strong argumentative points. Yet some of the argument still needs more elucidating.

    Full Text Available The correspondence of 1948 between Karl Popper and Michael Oakeshott, translated for the first time in Italian and published in the appendix to this paper, demonstrates the existence of two different ways of thinking about politics: the rationalist approach, founded on the “argumentation” as a rational means for the non-violent solution of problems (Popper, and the traditionalist mode, inspired by the method of “conversation” as a guarantee of constant openness to the diversity of identities (Oakeshott. To rise from the letters is a mutual influence on the interpretation of the key concepts that characterize the thought of the two authors, which however does not cancel the fundamental divergence of their political orientation.

    2014-01-01

    Full Text Available As is the case with other thinkers linked to what can be broadly defined as conservatism, it is arguable whether Michael Oakeshott was just a conservative, or whether he was also a liberal. He often rejected this last label. He also tried to avoid the classic debate between the left/right wing divide, conferring instead a mantle of neutrality on his work. This analysis shows, on the one hand, that Oakeshott´s work is ideologically orientated and, on the other hand, that it contains a substantial liberal component. In fact, he offered a liberal-conservative synthesis in which the free market appears to be not only the best, but the only feasible outcome in the proposed scenario of political prudence. I will fi rst connect Oakeshott with the main traditions of thought, then analyse the theoretical implications of his position, and finally explore the consequences derived from all this for everyday political practice.

    A study of the organocatalytic activity of N-heterocyclic carbenes (NHCs) in the Michael addition of 1,3-dicarbonyl compounds has allowed us to identify 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) as an excellent catalyst for this transformation (up to 99 % yield with a 2.5 mol % catalyst loading), and the reaction was found to be of broad scope. Two early applications of this unprecedented catalytic activity of NHCs are described, that is, the domino carbocyclization reactions of simple cyclic 1,3-dicarbonyl and malonic acid derivatives, which allow stereoselective access to bridged bicyclic compounds, and the stereoselective synthesis of cyclohexanols (or cyclohexene). Early mechanistic investigations are also reported. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  10. Inverting the diastereoselectivity of the mukaiyama-michael addition with graphite-based catalysts

    KAUST Repository

    Acocella, Maria Rosaria

    2014-02-07

    Here, we show that graphite-based catalysts, mainly graphite oxide (GO) and exfoliated GO, are effective recyclable catalysts for a relevant stereoselective Mukaiyama-Michael addition, outperforming currently available catalysts. Moreover, the graphite-based catalysts described here invert the diastereoselectivity relative to that observed with known catalysts, with the unprecedented large prevalence of the anti diastereoisomer. This inverted diastereoselectivity is increased when the catalyst concentration is reduced and after catalyst recycling. Density functional theory calculations suggest that the selectivity is determined by two types of supramolecular interactions operating between the catalyst and the substrates at the diastereoselectivity- determining transition state, specifically, the π-stacking of b-nitrostyrene with graphite and the van der Waals interaction between the SiMe3 group of the silyl ether and the graphite. © 2013 American Chemical Society.

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Michael Oakeshott conceives the history of European political thought as a structuring of ideas and arguments of the practical experience aimed to understanding political expressions in vogue in the culture of a people. It is not a continuous and cumulative history of abstract and disembodied ideas, as it is wrongly conceived, but of some men who thought politics in a certain way on the basis of the language and of the set of actions, moral beliefs and contingencies of the people which they belong to. The article highlights the comparison between Oakeshott, Quentin Skinner and Gianfranco Miglio on the search for the most appropriate method to be applied in the study of the history of political thought.

    Shape memory polymers (SMPs) based on natural rubber were fabricated by crosslinking epoxidized natural rubber with zinc diacrylate (ZDA) using the oxa-Michael reaction. These SMPs possessed excellent shape fixity and recovery. The glass transition largely accounted for the fixing of the SMPs temporary shape. Increasing the ZDA content allowed the trigger temperature (20-46 °C) and recovery time (14-33 s) of the SMPs to be continuously tuned. Nanosized silica (nanosilica) was incorporated into the neat polymers to further increase the flexibility and tune the recovery stress. The nanosilica-SMPs exhibited exceptionally high strength in a rubbery state (>20 MPa). The nanosilica-SMPs exhibited high transparency, making them suitable in visible heat-shrinkable tubes.

  15. Organizing awareness and increasing emotion regulation: revising chair work in emotion-focused therapy for borderline personality disorder.

    Pos, Alberta E; Greenberg, Leslie S

    2012-02-01

    Emotion-focused therapy (EFT) is an empirically supported treatment that may have potential as a stage-two treatment for borderline personality disorder (BPD). Specific aspects of BPD--the tendency to experience fluctuating self-states; weakness in meta-cognitive or reflective functioning; and the tendency for self-states to be organized by presently occurring interpersonal processes--present challenges to applying some EFT interventions with this population. In particular, even within a highly attuned, validating and accepting empathic relationship, clients with BPD may have difficulty with the usual manualizations of chair work interventions. This is because these interventions often employ polarization and intensification of experience in order to activate adaptive alternate emotional resources and self organizations. For the client with borderline personality disorder, these interventions may be counter-productive, emotionally dysregulating and disorganizing. EFT chair work, however, also has the potential to provide structure to the borderline clients experience of self, to stimulate metacognitive awareness, provide an alive experience of the process of polarization, attenuate emotional activation, and increase the experience of self-coherence. This article describes the development of stepwise approximations of EFT two-chair intervention for self-critical splits. It outlines potential stages of two-chair work as well as intervention principles important for productive chair work with this population. The EFT change principles of awareness, expression regulation, reflection, transformation, and corrective experience still centrally apply. However, several additional strategies are discussed to scaffold clients' capacity to both experience and regulate emotion.

    Chair rise performance is incorporated in clinical assessments to indicate fall risk status in older persons. This study investigated the test-retest reliability of a pendant-sensor-based assessment of chair rise performance. Forty-one older persons (28 females, 13 males, age: 72-94) were assessed in two sessions with 3 to 8 days in between. Repeated chair rise transfers were measured after different instructions. Relative and absolute test-retest reliability of chair rise measurements in individual tests and average over all tests were evaluated by means of intra-class correlation coefficients (ICCs) and standard error of measurement (SEM) as a percentage of the measurement mean. Systematic bias between the measurements in test and retest was examined with paired t-tests. Heteroscedasticity of the measurements was visually checked with Bland-Altman plots. In the different test conditions, the ICCs ranged between 0.63 and 0.93, and the SEM% ranged between 5.7% and 21.2%. The relative and absolute reliability of the average over all tests were ICC = 0.86 and SEM% = 9.5% for transfer duration, ICC = 0.93 and SEM% = 9.2% for maximum vertical acceleration, and ICC = 0.89 and SEM% = 10.0% for peak power. The results over all tests indicated that a fall risk assessment application based on pendant-worn-sensor measured chair rise performance in daily life might be feasible.

    Total knee arthroplasty is effective to regain quality of life. Standing up from and sitting down on a chair and stair stepping motion are important in daily living. We previously reported in vivo kinematics of this implant during a stepping exercise. The purpose of this analysis was to assess in vivo knee motion during standing up from and sitting down on a chair and determine the motion pattern in patients with the unique knee prosthesis. A total of 15 patients implanted with Bi-Surface PS were assessed during standing up from and sitting down on a chair. The Bi-Surface PS knee is a posterior-cruciate substitute prosthesis with a unique ball-and-socket joint in the mid-posterior portion of the femoral and tibial components. Patients were examined during standing up from and sitting down on a chair using a two-dimensional to three-dimensional registration technique. During standing up from and sitting down on a chair from minimum to 30° knee flexion, anterior femoral translation was slight. From 30° knee flexion to maximum flexion, the kinematic pattern was a medial pivot and rollback. This study demonstrated that the knee motion kinematic patterns observed in this study were not similar to normal knee kinematics and derived from the unique design of the Bi-Surface PS.

    A lack of diversity has been observed in radiation oncology (RO), with women and certain racial/ethnic groups underrepresented as trainees, faculty, and practicing physicians. We sought to gain a nuanced understanding of how to best promote diversity, equity, and inclusion (DEI) based on the insights of RO department chairs, with particular attention given to the experiences of the few women and underrepresented minorities (URMs) in these influential positions. From March to June 2016, we conducted telephone interviews with 24 RO department chairs (of 27 invited). Purposive sampling was used to invite all chairs who were women (n = 13) or URMs (n = 3) and 11 male chairs who were not URMs. Multiple analysts coded the verbatim transcripts. Five themes were identified: (1) commitment to DEI promotes quality health care and innovation; (2) gaps remain despite some progress with promoting diversity in RO; (3) women and URM faculty continue to experience challenges in various career domains; (4) solutions to DEI issues would be facilitated by acknowledging realities of gender and race; and (5) expansion of the career pipeline is needed. The chairs' insights had policy-relevant implications. Bias training should broach tokenism, blindness, and intersectionality. Efforts to recruit and support diverse talent should be deliberate and proactive. Bridge programs could engage students before their application to medical school. Copyright © 2018 Elsevier Inc.

    Holtshousen, W S J; Coetzee, E

    2012-09-01

    An analysis of annual reports revealed that on average 20% of patient appointments with oral hygienists in the Department of Health in the Pretoria region were not utilised due to patient noncompliance (i.e. broken appointments). Many solutions have been considered to address the high rate of noncompliance and the resulting idle chair capacity. One solution selected to overcome some of the negative consequences of broken appointments was deliberate overbooking. The aim of our study was to determine the effect of overbooking on idle dental chair capacity by measuring the utilisation rate over a three month period (July to September) after 25% overbooking was introduced in the Pretoria region. A statistical analysis was conducted on our results to determine an overbooking rate that would ensure full utilisation of the available dental chair capacity. The available time units over the three month study period amounted to 1365, allocated to 1427 patients resulting in an overal overbooking rate of 4.54%. The overall utilisation rate was found to be 79.2%. The calculated regression line estimated that there would be full utilisation of dental chair capacity at an overbooking rate of 26.7%. Overbooking at the levels applied in this study had a minimal overall effect on idle dental chair capacity. Our results confirm the need for careful planning and management in addressing noncompliance. In a manner similar to the clinical situation, organisational development requires a correct diagnosis in order that an appropriate and effective intervention may be designed.

    2015-01-01

    This volume presents five different methods recently developed to tackle the large scale behavior of highly correlated random systems, such as spin glasses, random polymers, local times and loop soups and random matrices. These methods, presented in a series of lectures delivered within the Jean-Morlet initiative (Spring 2013), play a fundamental role in the current development of probability theory and statistical mechanics.
