Lidar Strip Adjustment with Automatically Reconstructed Roof Shapes
Authors: Rentsch Matthias , Krzystek Peter 
Published: September 2012

AbstractIn recent years, the performance of lidar systems has steadily improved due to an increase in the achievable point density. The main error sources affecting the quality of lidar‐derived secondary products such as digital terrain models (DTMs) and digital surface models (DSMs) are the result of systematic errors coming from insufficient boresight calibration. The effects of boresight misalignments are visually recognised as discrepancies of the laser point clouds at selected objects (such as building roofs) in overlapping areas of neighbouring lidar strips. In this work, a strip adjustment method is presented that corrects the systematic errors of the laser point cloud using five strip parameters (three shifts plus two angular corrections for heading and roll). The strip adjustment procedure uses 2D and 3D tie elements and takes advantage of a new 3D measurement technique applied to building roofs. The strip adjustment method is applied to three different datasets, consisting of conventional first/last pulse and full‐waveform data. The results show that systematic discrepancies are typical for datasets that have already been processed by the flight companies. These errors can be reduced by more than 70% by applying the new strip adjustment approach. Preliminary investigations indicate that a higher laser point density and the inclusion of intensity and pulse width within full‐waveform lidar data lead to better results.
Public and Private Worlds? Social History, Gender and Space
Authors: Williamson Fiona 
Published: September 2012

AbstractMichael McKeon’s The Secret History of Domesticity is an important contribution to cultural and literary history, exploring how concepts of public and private evolved. His quest to uncover the ‘division of knowledge’ takes the reader on a journey through the low and high culture of literary genre, the history of print, art, architecture, entertainment, politics and social theory. This essay compares McKeon’s reading of public and private in light of the recent ‘spatial turn’ in social and gender history. The ‘spatial turn’ offers a close lens into the lived experience of past peoples in the same way that McKeon claims to recover the tacit knowledge embedded in the consciousness of past societies. The difference between the approaches is less about their conclusions, but their sources and methodology. Taken together they offer something that each alone cannot, a broad portrayal of a society from above and below, from the past and the present. In which case, there can be great value in placing cultural readings of the past, like Secret History, alongside social methodologies to draw together the experiences of people at all levels of society. In this article, I therefore argue for the inclusion of these contrasting and complimentary approaches to concepts of public and private within the framework of debate for Secret History.

SummaryPurpose:  To define the relationship between the epileptogenic zone and the polymicrogyric area using intracranial electroencephalography (EEG) recordings in patients with structural epilepsy associated with regional infrasylvian polymicrogyria (PMG).Methods:  We retrospectively reviewed the medical charts, scalp, and intracranial video‐EEG recordings, neuroimaging findings, and neuropsychological evaluations of four patients with refractory temporal lobe epilepsy related to PMG who consequently underwent resective surgery.Key Findings:  High‐resolution magnetic resonance imaging (MRI) revealed temporal lobe PMG in all cases, accompanied by hippocampal malrotation and closed lip schizencephaly in 3/4 cases, respectively. In intracranial recordings, interictal spike activity was localized within the PMG in only 2/4 and within the amygdala, hippocampus, and entorhinal cortex in all cases. In the first patient, two epileptogenic networks coexisted: the prevailing network initially involved the mesial temporal structures with spread to the anterior PMG; the secondary network successively involved the anterior part of the PMG and later the mesial temporal structures. In the second patient, the epileptogenic network was limited to the mesial temporal structures, fully sparing the PMG. In the third patient, the epileptogenic network first involved the mesial temporal structures and later the PMG. Conversely, in the last case, part of the PMG harbored an epileptogenic network that propagated to the mesial temporal structures. Consistent with these findings a favorable outcome (Engel class I in three of four patients; Engel class II in one of four) at last follow‐up was obtained by a resection involving parts of the PMG cortex in three of four and anteromesial temporal lobe structures in another three of four cases.Significance:  Infrasylvian PMG displays a heterogeneous epileptogenicity and is occasionally and partially involved in the epileptogenic zone that commonly includes the mesial temporal structures. Our results highlight the intricate interrelations between the MRI‐detectable lesion and the epileptogenic zone as delineated by intracranial recordings. Seizure freedom can be accomplished as a result of a meticulous intracranial study guiding a tailored resection that may spare part of the PMG.
The Relationship Between Nurses’ Perception of Work Environment and Patient Satisfaction in Adult Critical Care
Authors: Boev Christine 
Published: September 2012

AbstractBackground: Patient satisfaction in critical care is rarely measured yet has a major impact on hospital reimbursement. The critical care setting is characterized by high patient acuity and a fast‐paced work environment. Nurses’ perception of work environment in relation to various patient outcomes including patient satisfaction has not been explored exclusively in critical care.Objectives: (a) Examine patient's perception of nursing care associated with their hospitalization in the intensive care unit. (b) Describe nurses’ perception of work environment within a defined sample of adult critical care units, using the Practice Environment Scale of the Nursing Work Index (PES‐NWI). (c) Explore the relationships between nurses’ perception of work environment and patient satisfaction in adult critical care.Methods: This study used existing data to address the study aims. Unit‐level comparisons were examined using analysis of variance. The final aim was examined using multilevel modeling for longitudinal data.Results: Patients were very satisfied with their hospitalization (4.48 out of 5.0). Significant differences were noted among all unit level comparisons (p < .001). Nurses also reported moderate satisfaction with work environment as measured by the PES‐NWI, with perception of the role of their nurse manager receiving the highest scores. Perception of nurse manager leadership and ability was significantly related to patient satisfaction (p= .018). Favorable perception of the nurse manager was associated with a .424 point increase in patient satisfaction.Conclusions: This study offers preliminary support for the relationship between nurses’ perception of work environment and patient satisfaction in critical care. It also highlights the pivotal role of the nurse manager in both nurse and patient satisfaction.Clinical Relevance: This study examines two important aspects that are both relevant and important to clinical nursing. The first aspect is the healthy work environment. Multiple studies have linked the nursing work environment to patient outcomes and this is an area that deserves further attention. The second aspect, patient satisfaction, is now associated with hospital reimbursement. The relationship between the nursing work environment and patient satisfaction highlights an important link to improving patient care.
Art and Ambiguity: An Extended Review of Border Zones at the Museum of Anthropology, British Columbia
Authors: Fuglerud Øivind 
Published: September 2012

AbstractIn the last decade, an emphasis on aesthetics has become a prominent strategy for ethnographic museums that try to sever their connections to a history of colonialism and to overcome the dilemmas and difficulties involved in representing societies and cultures that are different from their own. Implicitly, and sometimes explicitly, aesthetics and art are projected as being intuitively understandable—a common ground where the politics of representation can be avoided. This article reviews the exhibition entitled Border Zones: New Art Across Cultures, which is a temporary exhibition that, following a lengthy rebuilding period, opened at the Museum of Anthropology (MoA) in Vancouver in 2010. In this article, I attempt to situate the exhibition within the MoA's own “exhibitionary narrative” and within a landscape of contemporary art. I argue that Border Zones represents a continuity with the MoA's permanent exhibitions but question the extent to which it lives up to the MoA's own vision of “multiversity” or a critical museology based on the need to deconstruct the pretensions of Western science.

Published: September 2012

Positive temperature coefficient of resistivity (PTCR) ceramics of 0.912(Ba1+xTiO3)–0.088(Bi0.5Na0.5TiO3) (BT–BNT) (x = −0.03 to 0.03) were prepared using the mixed oxide route and sintered at 1340°C for 4 h. Products were predominantly single phase with a tetragonal structure and grains in 2–6 μm size containing 90° ferroelectric domains. Samples with Ti/Ba > 1 contained second‐phase Ba6Ti17O40. HRTEM and aberration‐corrected Z‐contrast high angle annular dark field scanning transmission electron microscopy (HAADF‐STEM) suggested that the dopants, Bi and Na, occupy the Ba site of the perovskite lattice, and revealed the presence of dissociated dislocations in x = −0.03 and x = 0.00 materials. The interval between two partial dislocations was 1.9–3.4 nm, yielding stacking fault energies of 363–649 mJ/m2. The PTCR behavior of the ceramics increased with Ti/Ba content, reaching a maximum of six decades change in resistivity for x = −0.03. The anomalous increase in resistivity depends critically on stoichiometry, increasing with the Ti/Ba ratio; this in turn is directly correlated with an increase in the amount of second‐phase Ba6Ti17O40, an increase in the stacking fault energy, and an increase in the tilt angle of the grain boundaries.
Restricted Theological Voluntarism
Authors: Murphy Mark C. 
Published: September 2012

AbstractIn addressing objections to the theological voluntarist program, the consensus response by defenders of theological voluntarism has been to affirm a restricted theological voluntarism on which some, but not all, important normative statuses are to be explained by immediate appeal to the divine will. The aim of this article is to assess the merits and demerits of this restricted view. While affirming the restricted view does free theological voluntarism from certain objections, it comes at the cost of committing the theological voluntarist to the view that no theses about the divine nature itself could alone be sufficient to motivate a theological voluntarist thesis about any normative status. And when we examine the case for a theological voluntarist account of any particular normative status – say, rightness, or obligatoriness – there are severe difficulties with that case as it stands. It is thus unclear whether the theological voluntarist program of providing good reasons to affirm a voluntarist explanation of non‐trivially‐theistic normative statuses has borne fruit.

Published: September 2012

AbstractInformation from 15 satellite‐tracked Antillean manatees (Trichechus manatus manatus) was analyzed in order to assess individual movements, home ranges, and high‐use areas for conservation decisions. Manatees were captured in Chetumal Bay, Mexico, and tagged with Argos‐monitored satellite transmitters. Location of the manatees and physical characteristics were assessed to describe habitat properties. Most manatees traveled to freshwater sources. The Maximum Area Size (MAS) for each manatee was determined using the observation‐area method. Additional kernel densities of 95% home range and 50% Center of Activity (COA) were also calculated, with manatees having 1–3 COAs. Manatees exhibited two different movement patterns: remaining in Chetumal Bay, and long‐distance (up to 240 km in 89 d). The residence time in Chetumal Bay was higher for females (89.6% of time) than for males (72.0%), but the daily travel rate (0.4–0.5 km/d) was similar for both sexes. Most of the COAs fell within Natural Protected Areas (NPA). However, manatees also travel for long distances into unprotected areas, where they face uncontrolled boat traffic, fishing activities, and habitat loss. Conservation of movement corridors may promote long‐distance movements and facilitate genetic exchange.
Plant mitochondrial genome peculiarities evolving in the earliest vascular plant lineages
Authors: KNOOP Volker 
Published: September 2012

AbstractIn plants, the mitochondrial DNA has evolved in peculiar ways. Simple circular mitochondrial genomes found in most other eukaryotic lineages have expanded tremendously in size. Mitochondrial DNAs in some flowering plants may in fact be larger than genomes of free‐living bacteria. Introns, retrotransposons, pseudogene fragments, and promiscuous DNA copied from the chloroplast or nuclear genome contribute to the size expansion but most intergenic DNA remains unaccounted for so far. Additionally, frequent recombination results in heterogeneous pools of coexisting, subgenomic mtDNA molecules in angiosperms. In contrast, the mitochondrial DNAs of bryophytes, the extant representatives of very early splits in plant phylogeny, are more conservative in structural evolution and seem to be devoid of active recombination. However, whereas mitochondrial introns are highly conserved among seed plants (spermatophytes), not a single one of more than 80 different introns in bryophyte mtDNAs is conserved among the three divisions, liverworts, mosses, and hornworts. Lycophytes are now unequivocally identified as living representatives of the earliest vascular plant branch in a crucial phylogenetic position between bryophytes and later diversifying tracheophytes including spermatophytes. Very recently, mtDNAs have become available for the three orders of extant lycophytes—Isoetales, Selaginellales, and Lycopodiales. As I will discuss here, the lycophyte mtDNAs not only show a surprising diversity of features but also previously unseen novelties of plant mitochondrial DNA evolution. The transition from a gametophyte‐dominated bryophyte lifestyle to a sporophyte‐dominated vascular plant lifestyle apparently gave rise to several peculiar independent changes in plant chondrome evolution.
Nature of fatigue moderates depressive symptoms and anxiety in sarcoidosis

Published: September 2012

ObjectivesFatigue, depressive symptoms, and anxiety are frequently reported in sarcoidosis. However, the relationship between these debilitating symptoms is unclear. Therefore, the purpose of this prospective follow‐up study was to identify the prevalence of depressive symptoms and anxiety in sarcoidosis patients, stratified for the nature of fatigue. In addition, we examined whether depressive symptoms and anxiety predicted fatigue.DesignThis is a prospective follow‐up study.MethodsSarcoidosis outpatients (n = 274) were included. Clinical data were obtained from medical records. At baseline, patients completed the Fatigue Assessment Scale (FAS), the Center for Epidemiological Studies‐Depression Scale (CES‐D), and the State and Trait Anxiety Inventory (STAI). After 6, 12, and 18 months patients completed the FAS again.ResultsConcomitant fatigue (FAS > 21) and high‐trait anxiety (STAI > 40) was frequently reported (35–36%). The combination of fatigue and high levels of depressive symptoms (CES‐D > 16) was reported in 43–46%. Combined high‐trait anxiety and high levels of depressive symptoms were reported in 31% of the patients. These percentages were higher in patients with all day fatigue, compared with patients with intermittent, or mild fatigue. Both anxiety and depressive symptoms were significant predictors of high fatigue scores.ConclusionsNature of fatigue moderates the relationships between fatigue and anxiety and fatigue and depressive symptoms in sarcoidosis. Hence, beside fatigue, depressive symptoms and anxiety should be an integral part of the multidisciplinary management of sarcoidosis patients.Statement of contributionWhat is already known on this subject? Fatigue is a frequently reported symptom in sarcoidosis. Symptoms such as depressive symptoms and anxiety are also prevalent in sarcoidosis. However, the relationships between these symptoms are still unclear and require more research.What does this study add? This paper shows that fatigue is often accompanied by depressive symptoms and anxiety, although these symptoms are not fully overlapping. In addition, depressive symptoms and anxiety predict fatigue after follow‐up. Fatigue, depressive symptoms and anxiety are most strongly correlated in patients with All Day Fatigue, which indicate that these patients may benefit from psychological interventions in the management of fatigue.
Evaluating a visual timeline methodology for appraisal and coping research
Authors: Mazzetti Angela , Blenkinsopp John 
Published: September 2012

Theoretical models of stress have become increasingly sophisticated, recognizing the importance of context and history, yet the principal data‐gathering method used by researchers remains the self‐report questionnaire, a method which is conspicuously ill suited to obtaining data which would allow for exploration of these factors. In this article, we explore the use of visual methods as an alternative to traditional methods, presenting the findings of a study designed to test the utility of a visual timeline technique. A key contribution of this article is the application of an alternative technique for researching stress appraisal and coping. The technique conferred a number of benefits that may not have been provided by more conventional approaches, making it a suitable basis for the exploration of stress appraisal and coping. A further contribution is the identification of a straightforward process for analysing the visual data produced.Practitioner Points

Understanding appraisal and coping in terms of history and context is crucial to the design of effective stress interventions.
The visual timeline method offers practitioners an alternative way of gathering data to inform the design of appropriate interventions.
It may be especially useful in working with individuals and organizations coping with change: the method was positively evaluated by participants, who found the experience enjoyable and beneficial, so it may elicit more engagement than traditional methods for gauging employee responses to change, such as attitude surveys.

AbstractNannopus palustris Brady, 1880	is a free‐living widely distributed harpacticoid copepod, which has been formerly assumed to be a single, cosmopolitan but highly variable species. We compared several geographically distant N. palustris populations in terms of their morphology and genetics. Populations from the White Sea (WS), the North Sea (NS), the Black Sea (BS) and two sympatric morphs from South Carolina, USA (SC notched and SC straight morphs), were considered. The NS, BS and to a lesser extent SC notched specimens were morphologically similar and partly coincided to the ‘canonical’ description of the species. By contrast, WS population showed remarkable anatomical and morphometric peculiarities that correspond to some earlier descriptions. Genetic analyses of mitochondrial (cytochrome b) and nuclear (28S rDNA) genes demonstrated the significant distinctness among WS, both SC and (NS+BS) populations, the latter two being genetically indistinguishable. Concordance between mitochondrial and nuclear gene trees and morphological data supports that N. palustris is in fact composed of several pseudo‐sibling species, which are genetically and morphologically divergent. Neither correlation between genetic divergence and geographical distance nor significant intrapopulation diversity was found for these species. Taxonomic status, distribution and phylogenetic relationships of the species within the Nannopus genus need to be reconsidered. A further subdivision of species complexes might have important implications for the analysis of biodiversity of benthic copepods and consequently for the interpretation of their (species‐specific) ecological function.

SummaryBackgroundAlpha‐2 adrenergic agonists are used to premedicate pediatric patients to reduce separation anxiety and achieve calm induction. The clinical effects of clonidine are similar whether via the oral or nasal route. However, oral dexmedetomidine is not preferred because of its poor bioavailability. The objective of this study was to evaluate the effects of nasal versus buccal dexmedetomidine used for premedication in children.MethodsSixty‐two patients, aged 2–6 years, undergoing minor elective surgery were randomly assigned to two groups to receive dexmedetomidine, either 1 μg·kg−1 buccally (group B) or 1 μg·kg−1 intranasally (group N) for premedication 45 min before the induction of anesthesia. Heart rate, peripheral oxygen saturation, and respiratory rate were measured before and every 10 min after administering dexmedetomidine in all children. Level of sedation was assessed every 10 min until transport to operating room. Drug acceptance, parental separation, and face mask acceptance scores were recorded.ResultsThere was no significant difference between the two groups in patient characteristics, nor was there any significant difference between the two groups in heart rate, respiratory rate, or SpO2 values at all times after premedication. Levels of sedation, parental separation, and mask acceptance scores were significantly higher in group N than in group B at the various times.ConclusionsThese results suggest that intranasal administration of 1 μg·kg−1 dexmedetomidine is more effective than buccal administration of 1 μg·kg−1 dexmedetomidine for premedication in children.
