“Growing from an Invisible Wound” A Humanistic-Existential Approach to PTSD

From a humanistic and existential perspective, posttraumatic stress disorder (PTSD) can be understood as a normal response to a threatening existential event. The humanistic-existential approach to understanding and treating PTSD also places particular emphasis on the meaning of the traumatic experience and on the awareness of the existential part of the self. Such an understanding conveys to a different approach to trauma assessment and potential for healing in the clinical encounter. In this chapter, we wish to provide a humanistic-existential understanding of trauma. To do so, we review the key humanistic-existential concepts for trauma conceptualization, assessment, and intervention. Afterwards, we present two different short case studies to illustrate and understand the humanistic-existential psychotherapeutic process and its diversity. In conclusion, we discuss the contribution and limits of a humanistic-existential approach to trauma conceptualization, assessment, and healing

A Review of the Relationship of the ENC and DNC Hydrographic Vector Data Products

This document discusses the level of harmonization between the S-57 and DIGEST standards and the relationship between the ENC and DNC products. It is shown that the military and regulated commercial navigation have different needs, and that it is natural to have two different standards. However, in those areas where the needs overlap the standards should be equivalent. Commercial navigation requires "official" data whereas the military require a broad range of the "best available data". These needs are complementary. At the content level ENC data can be a pure subset of DNC data, however additional harmonization is required to achieve this

Phase Diagram of CeCoIn_5 in the Vicinity of H_{c2} as Determined by NMR

We report ^{115}In nuclear magnetic resonance (NMR) measurements in the heavy-fermion superconductor CeCoIn_5 as a function of temperature in different magnetic fields applied parallel to the $(\hat a, \hat b)$ plane. The measurements probe a part of the phase diagram in the vicinity of the superconducting critical field H_{c2} where a possible inhomogeneous superconducting state, Fulde-Ferrel-Larkin-Ovchinnikov (FFLO), is stabilized. We have identified clear NMR signatures of two phase transitions occurring in this part of the phase diagram. The first order phase transitions are characterized by the sizable discontinuity of the shift. We find that a continuous second order phase transition from the superconducting to the FFLO state occurs at temperature below which the shift becomes temperature independent. We have compiled the first phase diagram of CeCoIn_5 in the vicinity of H_{c2} from NMR data and found that it is in agreement with the one determined by thermodynamic measurements.Comment: 4 pages, submitted to Proceedings of SCES'0

Development and Characterisation of a Gas System and its Associated Slow-Control System for an ATLAS Small-Strip Thin Gap Chamber Testing Facility

A quality assurance and performance qualification laboratory was built at McGill University for the Canadian-made small-strip Thin Gap Chamber (sTGC) muon detectors produced for the 2019-2020 ATLAS experiment muon spectrometer upgrade. The facility uses cosmic rays as a muon source to ionise the quenching gas mixture of pentane and carbon dioxide flowing through the sTGC detector. A gas system was developed and characterised for this purpose, with a simple and efficient gas condenser design utilizing a Peltier thermoelectric cooler (TEC). The gas system was tested to provide the desired 45 vol% pentane concentration. For continuous operations, a state-machine system was implemented with alerting and remote monitoring features to run all cosmic-ray data-acquisition associated slow-control systems, such as high/low voltage, gas system and environmental monitoring, in a safe and continuous mode, even in the absence of an operator.Comment: 23 pages, LaTeX, 14 figures, 4 tables, proof corrections for Journal of Instrumentation (JINST), including corrected Fig. 8b

Hydrographic Data Standards and Standards-based Geospatial Data Infrastructures

The global leadership shown by the International Hydrographic Organization (IHO) in leading the development and implementation of international standards for the paper navigational chart has been successfully carried over into the digital domain. This has been demonstrated by the acceptance and use of the S57 and S52 data standards for Electronic Navigational Charts (ENCs). The IHO has also been careful to ensure that S57 and S52 retain upward compatibility with other emerging international standards for geospatial data. The first part of the paper reviews the position and status of S57 in re lation to this new standards environment. The second part of the paper considers the influence of the Internet which is having a major influence on the emerging geospatial data infrastructures that are being built in a number of countries and impacting the distribution and use of geospatial data, and will also provide opportunities for, and have an effect on the provision of data by hydrographic offices

Pip and Pop: When auditory alarms facilitate visual change detection in dynamic settings

Dynamic and complex command and control situations often require the timely recognition of changes in the environment in order to detect potentially malicious actions. Change detection can be challenging within a continually evolving scene, and particularly under multitasking conditions whereby attention is necessarily divided between several subtasks. On-screen tools can assist with detection (e.g., providing a visual record of changes, ensuring that none are overlooked), however, in a high workload environment, this may result in information overload to the detriment of the primary task. One alternative is to exploit the auditory modality as a means to support visual change detection. In the current study, we use a naval air-warfare simulation, and introduce an auditory alarm to coincide with critical visual changes (in aircraft speed/direction) on the radar. We found that participants detected a greater percentage of visual changes and were significantly quicker to detect these changes when they were accompanied by an auditory alarm than when they were not. Furthermore, participants reported that mental demand was lower in the auditory alarm condition, and this was reflected in reduced classification omissions on the primary task. Results are discussed in relation to Wickens’ multiple resource theory of attention and indicate the potential for using the auditory modality to facilitate visual change detection

Effects of depressive symptomatology on cancer‐related symptoms during oral oncolytic treatment

ObjectiveThis manuscript assesses association between depressive symptoms and symptoms from cancer and its treatment during the first 12 weeks of a new oral oncolytic treatment.MethodsThis secondary analysis used data from a recently completed trial of an intervention to improve adherence to oral oncolytic treatment and manage symptoms. Following the initiation of the new oral oncolytic medication, 272 patients were interviewed at intake and weeks 4, 8, and 12 to assess depressive symptoms, and symptoms from cancer and its treatment. Depressive symptoms were measured using the Center for Epidemiologic Studies‐Depression (CES‐D20). The summed index of 18 cancer‐related and treatment‐related symptoms as well as the number of symptoms above threshold at intake, weeks 4, 8, and 12 were related to intake and time‐varying CES‐D20 using linear mixed effects models.ResultsDepressive symptomatology was a significant predictor of cancer‐related and treatment‐related symptoms at all‐time points, but the strength of this relationship was greatest at the time of oral oncolytic agent initiation and at week 4. The strength of this relationship was the same for both summed symptom severity index and the number of symptoms above threshold, and using either intake or time‐varying CES‐D20.ConclusionIntroducing strategies to treat and manage symptoms of depression along with other symptoms might have added benefits among patients who start a new oral oncolytic treatment and report modest to higher levels of depressive symptoms. Assessments for the impact of strategies to lower depressive symptoms can be taken within the first 4 weeks.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147865/1/pon4916.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/147865/2/pon4916_am.pd

Intercomparison of two-dimensional wave spectra obtained from microwave instruments, buoys and WAModel simulations during the surface wave dynamics experiment

An intercomparison is made of two dimensional wave spectra obtained from buoys and various remote sensing microwave systems and predicted by the WAModel dur- ing the Surface Wave Dynamics Experiment (SWADE). The overall agreement be- tween the measurements and the model is satifactory, but some differences in detail require further investigation. The buoy data yield reliable mean spectral parame- ters, but the maximum likelihood retrieval algorithm tends to produce directional distributions that are broader than those of other instruments. Various microwave instruments (ROWS, RESSAC, SRA) show good promise for the determination of 2d-wave spectra, but exhibit individual shortcomings (calibration uncertainties, di- rectional ambiguity, impact of aircraft motion) that need to be further studied. The SAR system yields reliable retrievals with respect to the general spectral dis- tribution, but suffers in this experiment from an undetermined calibration factor. Deviations between the WAModel and instrumental data could be largely attributed to wind field errors, but the model also exhibits deficiencies in the development of short-fetch wave systems and in the wave spectral response to rapidly turning wind fields
