Abstract:
AbstractState and local pension plans are increasingly moving from the traditional defined benefit (DB) model to non-DB models that generally allow for participant-directed investment. This shift has important implications for the management of the more than US$3 trillion in assets held to finance public employee retirement benefits. To investigate these implications, we introduce new data from a nationwide survey of public DB and non-DB plans and a unique data set on thousands of individual investors in the state of Florida's defined contribution (DC) plan. Using these sources, we explore how participant involvement in the public sector affects the distribution of asset class allocations, management fees, investment outcomes, and portfolio rebalancing at both the individual and aggregate levels. We found that there is little difference between the DB and non-DB plans in terms of asset mix, returns, and fees, except that DB plan have greater access and allocations to alternative investments. We also found that while the average individual DC plan participant allocated their asset similarly to the DB plan, black females and older white males, on average, invested on opposite tails of the risk spectrum.

Abstract:
AbstractThe Pension Benefit Guaranty Corporation (PBGC) insures private sector defined benefit (DB) pension plans, when an employer becomes insolvent and is unable to pay the pension liabilities. In principle, the insurance premiums collected by PBGC should be sufficient to cover potential losses; this would ensure that PBGC could pay the insured benefits of terminated pension plan without additional external funding (e.g., from taxpayers). Therefore, the risk exposure of the PBGC from insuring DB pension plans arises from the probability of the employer insolvencies; and the terminating plans’ funding status (the excess of the value of the insured plan liabilities over the plan assets). Here we explore only the second component, namely the impact of plan underfunding for the operation of the PBGC. When a DB plan is fully funded, the PBGC's risk exposure for an ongoing plan is low even if the plan sponsor becomes insolvent. Thus the questions most pertinent to the PBGC are: what key risk factors can produce underfunding in a DB plan, and how can these risk factors be quantified? We discuss the key risk factors that produce DB pension underfunding, namely, investment risk and liability risk. These are interrelated and must be considered simultaneously in order to quantify the risk exposure of a DB pension plan. We propose that an integrated risk management model (an Integrated Asset/Liability Model) can help better understand DB pension plan funding risk. We also examine the Pension Insurance Modeling System developed by the PBGC in terms of its own use of some of the building blocks of an integrated risk management model.

Abstract:
AbstractMany organizations have either already terminated their defined benefit (DB) plans or are thinking about it, in order to offload the financial and regulatory risks these programs pose. But plan sponsors should think carefully about how their decision might affect their workers' commitment and productivity – and ultimately their organization's success.To answer those and other retirement questions, Watson Wyatt set out to learn how DB and defined contribution (DC) plans affect employees' workforce behavior and decisions. Watson Wyatt's Retirement Attitude Survey (WWRAS) found that, while most workers value both types of plans very highly, workers with DB plans generally appreciate their retirement programs significantly more than those with only a DC plan. This was particularly the case for those with a hybrid pension plan. This analysis found that retirement plan generosity and effective communication strongly affect a plan's perceived value to employees. This has important implications for plan sponsors, since greater plan appreciation is strongly linked to employee commitment. In fact, we found that workers covered by a defined benefit plan express a very strong commitment to their current employer, while DC plan coverage has no effect on employee commitment. This is partly owing to a selection effect, whereby firms with DB plans tend to attract more committed workers. However, even after controlling for the selection effect, DB plans exert an independent effect on the likelihood that employees will stay with their employer.

Abstract:
AbstractThis paper examines a natural experiment in which Washington State teachers were offered the opportunity to choose between enrolling in a traditional defined benefit (DB) plan and a hybrid plan with DB and defined contribution (DC) components. We find plan preference is weakly related to estimates of the relative financial benefits of being in either the DB or hybrid system and strongly related to teacher age. Importantly, we also find that the majority of teachers prefer the hybrid plan, and that teachers opting into the hybrid plan tend to be more effective based on student output measures of teacher productivity. These results suggest that policy shifts toward pension systems that include DC options do not necessarily make teaching a less desirable profession, particularly for the most productive employees.

Abstract:
The evolution of hybrid conversions has prompted a number of high-profile legal challenges. In response, policymakers have attempted to force companies transitioning from a traditional DB to a hybrid plan to offer all workers the open-ended choice of remaining in the old DB plan, versus switching to the new hybrid plan. This paper evaluates ‘winners’ and ‘losers’ under these plan conversions and estimates the cost to plan sponsors of such a mandate. We find that mandating choice could increase plan sponsors' pension expenses above their current cost for traditional defined benefit plans. In the end, rising costs of pensions could endanger plan sponsorship altogether. Policymakers seeking to mandate pension choice should take into account these possible undesirable outcomes of such a law.

Abstract:
Since 2002, public school teachers in Florida have been permitted to choose between a defined benefit (DB) and a defined contribution (DC) retirement plan. We exploit this unique policy environment to study new teachers’ revealed preferences over pension plan structures. Roughly 30 percent of teachers hired between 2003 and 2008 selected the DC plan, despite the fact that teachers not actively deciding within six months were defaulted into the DB plan. The share choosing the DC plan was higher among teachers with advanced degrees, math and science teachers, and teachers in charter schools. It was lower among special education teachers and especially among black and Hispanic teachers. There was only a slight relationship between plan choice and teacher value added to student achievement, with teachers in the bottom value-added quartile roughly 2 percentage points less likely to choose the DC option.

Abstract:
Dimensional metrology is of prime importance in the industrial and scientific domains, particularly in the field of quality control of manufactured products. In robotics too: without dimensional sensors, robots would be nothing else more than automatons, going through the same repetitive tasks again and again in a carefully controlled environment. This thesis deals with a noncontact measurement technique involving active vision, called triangulation under laser plane lighting. This optomechatronic method consists in projecting a laser sheet on an object or a surface under test, and analyzing the intersecting curve on an image taken by a camera. It allows making a wide variety of dimensional, noncontact and nondestructive, measurements (length, area, volume, diameter, curvature, reverse engineering,...). The original approach of the work is that the focus is brought on the determination of specific, restricted dimensional information on objects of diverse, but a priori known, shapes with the objective of achieving metrological performances in agreement with the industrial requirements. Furthermore, ambulatory instruments­i.e. devices that are at least portable, or even handheld­are exclusively aimed, using low-cost components. Another objective is to obtain systems for which an industrial transposition to innovative instrumental products is feasible. The text is divided in two distinct parts, both strongly correlated. The first one deals with all the theoretical aspects of the method: camera model, passage from 2-D image to 3-D scene, image processing, calibration, accuracy analysis... The performances of the developed models are also studied, in terms of robustness and repeatability. The second part describes four innovative applications of our own: the diameter measurement of cylindrical and of spherical objects, dimensional measurements in the building sector and the determination of the road surface microtexture. The achieved accuracies are globally of about 1%.

Abstract:
This chapter reviews available data on the annuity choices offered to retirees who participate in defined benefit (DB) plans. DB plans are most commonly offered by state and local governments to their employees, and information on annuity options is readily available. The authors examine all state pension plans that cover general state employees and teachers, and develop a table showing the similarities and differences across these approximately eighty separate state retirement plans. The authors determine the proportion of retirees selecting each of the annuity options. Where possible, annuity options in the public sector are compared to those offered by private sector employers. The chapter also reviews the empirical literature on who chooses the various annuity options offered in DB plans. Finally, the authors consider the policy implications of plan design and how this affects the types of annuities offered to retirees.

Abstract:
Diversification of DB applications highlighted the limitations of relational database management system (RDBMS) particularly on the modeling plan. In fact, in the real world, we are increasingly faced with the situation where applications need to handle imprecise data and to offer a flexible querying to their users. Several theoretical solutions have been proposed. However, the impact of this work in practice remained negligible with the exception of a few research prototypes based on the formal model GEFRED. In this chapter, the authors propose a new approach for exploitation of fuzzy relational databases (FRDB) described by the model GEFRED. This approach consists of 1) a new technique for extracting summary fuzzy data, Fuzzy SAINTETIQ, based on the classification of fuzzy data and formal concepts analysis; 2) an approach of assessing flexible queries in the context of FDB based on the set of fuzzy summaries generated by our fuzzy SAINTETIQ system; 3) an approach of repairing and substituting unanswered query.

Abstract:
Cavitation and embolization of plants accompanied by conduit vibration due to intermolecular adhesion of water or the adhesion of the conduit wall are signs of water stress. Ultrasonic acoustic emission (UAEs) was used to detect plant air pockets and embolic events transmitted by vibration. The UAEs could be detected in ultrasonic frequency between 100K Hz and 1 MHz. In general, the spatial location of UAEs sources for the influence of signal spatial distribution are greater than the UAEs signal wave shapes to the time. Using the electro-acoustic similarity theory, UAEs can be seen as the step voltage sources, the medium as the load, the water column rupture model (UAEs mutation model) in the plant conduit can be established by the analog circuit method. Without considering the change of plant stems medium density and ultrasonic velocity, the ultrasonic energy is proportional to square of the ultrasonic pressure. According to plant water stress relationships between ultrasonic energy release and ultrasonic energy, the UAEs ring counts or signal strength can be used to indicate the range and extent of plant conduits embolism, which can establish the model of UAEs and physiology by statistical laws. Studies have shown that the UAEs waves transmit in the plant fiber, signal attenuation in the fiber is a function of cell tissue hardness, and the approximate attenuation values are 1 dB/cm, 10 dB/cm and 20 dB/cm in hardwood, softwood and herbaceous plants, respectively.

By presenting a round space at the focal point of the ground plane, improved attributes of Microstrip patch antenna can be accomplished. The proposed Disc Shaped Microstrip patch antenna is reverberating at 5 GHz. Simulation has been finished by utilizing reenactment programming HFSS version15. From recreation results, it discovers that our examined Disc Shaped Microstrip patch antenna yields better return loss of - 25.1 dB & VSWR estimation of 0.96 dB. The examined DSMPA is yielding a higher radiation efficiency of 77.20 %. The minimized size and higher radiation efficiency contrasted with rectangular Microstrip patch antenna makes it all the more generally helpful for satellite communications.

Abstract:
This chapter introduces a novel design concept to reduce mutual coupling among closely-spaced antenna elements of a MIMO array. This design concept significantly reduces the complexity of traditional/existing design approaches such as metamaterials, defected ground plane structures, soft electromagnetic surfaces, parasitic elements, matching and decoupling networks using a simple, yet a novel design alternative. The approach is based on a planar single decoupling element, consisting of a rectangular metallic ring resonator printed on one face of an ungrounded substrate. The decoupling structure surrounds a two-element vertical monopole antenna array fed by a coplanar waveguide structure. The design is shown both by simulations and measurements to reduce the mutual coupling by at least 20 dB, maintain the impedance bandwidth over which S11, is less than −10 dB, and reduce the envelope correlation coefficient to below 0.001. The boresight of the far-field radiation patterns of the two vertical monopole wire antennas operating at 2.4 GHz and separated by 8 mm (λo/16), where λo is the free-space wavelength at 2.45 GHz, is shown to be orthogonal and inclined by 45° with respect to the horizontal (azimuthal) plane while maintaining the shape of the isolated single antenna element.

Full text
Abstract:
Orbital angular momentum (OAM) techniques are exploited for a wide range of potential radiofrequency (RF) and electromagnetic applications, including megahertz-through-terahertz wireless systems, fiber-based and free-space optical communications and sensing, just like acoustic and any other wave-based counterparts. In those RF and electromagnetic applications, OAM wave is set to enable the development of high-speed and high-capacity communications, radar imaging, and sensing systems, among many others. In this chapter, a comprehensive comparison between plane wave and OAM wave propagation using a patch antenna as a radiator at 2.45 GHz is presented and discussed. This comparison allows the appreciation of the fundamental properties of the OAM wave when compared against its plane wave counterpart. For simplified comparison and discussion, we will use two abbreviated terms: PWPA for plane-wave patch antenna and OWPA for OAM wave patch antenna. PWPA refers to as planar patch antenna that produces plane waves in far-field, whereas patch antenna that delivers OAM waves in far-field is termed as OWPA. In this context, all physical quantities for wave propagation such as electric field, magnetic field, wave impedance, wave vector, velocity, pitch, and propagation constant are theoretically studied for OAM waves and compared with plane waves. First, OAM wave generation is studied through widely used uniform circular antenna array (UCAA) in literature. Then, plane wave patch antenna (PWPA) and OAM wave patch antenna (OWPA) are designed and verified through simulation and measurement. OWPA is designed with characteristic mode analysis (CMA) based on a lossy substrate to excite a twisting wave at a determined patch location. With this in mind, a comparative investigation of PWPA and OWPA is conducted for different physical parameters. Cylindrical near-field scan clearly shows a helical wave motion for OWPA, whereas a normal plane wave motion for PWPA. Furthermore, the comparison of plane wave and OAM wave propagation is demonstrated using the combination of a Tx–Rx antenna pair. It is observed that the overall signal from OWPA can be received with two PWPAs at an angle as OWPA has a dispersive beam. Moreover, the receiving antenna with a large aperture and plane wave horn antenna (PWHA) in the line of sight (LOS) range can also be used to receive the overall signal from OWPA. The received signal in PWPA–PWPA, OWPA–OWPA, OWPA–PWPA–PWPA, OWPA–PWHA Tx–Rx pairs is thoroughly compared and studied. Measured and simulated results for transmission are −30 dB for 0 dB input signal in OWPA–PWPA–PWPA and OWPA–PWHA cases, which are reasonably justified within the sensitivity/dynamic range of short-distance communication and radar sensing receivers.

Abstract:
The Main10ance project aims to implement a plan of maintenance and conservation of the historical cultural heritage. This is an INTERREG project. The V-A Cooperation Programme Italy-Switzerland 2014-2020 contributes to the objectives of the Europe 2020 Strategy and the New Swiss Regional Policy (NRP)addressing the needs common to both sides of the border and aiming to generate significant change in the area of cooperation, both in terms of increasing competitiveness and strengthening economic and social cohesion. The case study is the system of the Sacri Monti of northern Italy and Switzerland, groups of chapels and other architectural artifacts. The design phases are divided into: survey of the historical architectural heritage present; data processing and realization of three-dimensional models with the help of BIM software; integration of the same in the geographical context through GIS support; creation of a database which creates interoperability between the various domains and which collects information on the characteristics of the goods for maintenance and conservation purposes; possibility to make the information associated with 3D models accessible through demonstrators that allow interrogation of the DB and the models themselves. The geometric representation respects the subdivision of the levels of detail (LOD) for GIS with the standard CityGML and the levels of development (LOD) for BIM with the UNI 11337/4.

Abstract:
Abstract A novel approach in organizing product data and managing product information in collaborative product design and development environments is presented. Domains of product data and information are first discussed in the context of generic models of product development process and product design process. An approach called the Product Information Management System (PRIMAS) for organizing and managing product information is subsequently described. In the system, product data is organized in a genome-like relational database (PRIMAS-DB), comprising a matrix of two categories of factors, namely, the Information Fields and the Product Constituents. The Information Fields consist of four generic domains for organizing information for the various activities represented as Product Constituents. The operational model and architecture of PRIMAS are presented. Development of a prototype for PRIMAS and plan for further work are described.

Abstract:
Electromagnetic shielding is needed to protect human beings from undesired non-ionizing radiation and to protect electronic equipment from EM interferences. Shielding solution of Electromagnetic Compatibility domain is tackled nowadays by modern manufacturing methods of flexible textile fabrics with electrically conductive properties. Our research focuses on the additional electromagnetic shielding effectiveness (EMSE) rendered by plasma coating of flexible woven fabrics with inserted conductive yarns. EMSE was computed for an experimental plan formed of plasma coating with Copper and Stainless steel with thicknesses of 400 nm and 1200 nm on both sides of woven fabrics with inserted conductive yarns of stainless steel and silver. An additional EMSE of 5-20 dB on the frequency range of 0.1-1000 MHz was achieved by plasma coating. This proves the enhancement of the shielding properties by magnetron plasma coating, without altering the bulk properties of textile fabrics, such as flexibility and mechanical resistance. The paper presents EMSE results in relation to fabric structure, raw metallic materials and frequency of the incident electromagnetic field.

Abstract:
Abstract This technical paper presents the strategy adopted by COMPANY for Remediation of On-Bottom Stability (OBS) Issue during offshore installation of Light Weight Structure (LWS) at Malaysia Water at water depth of 54m. The knowledge sharing is based on the successful remediation work in managing the OBS issue where the substructure experience excessive tilting. The LWS is designed with minimal mudmat. In addition to that, the subsea pin pile is designed to improve substructure on bottom stability issue during substructure installation. However, during actual offshore installation of substructure, the behavior of the substructure upon setting down on seabed was not as per the intended design where the substructure tilting is observed after substructure landing onto pin pile. As mitigation, the following approaches have been implemented to safeguard the substructure from toppling: Safeguard of SubstructureRisk assessment and immediate action have been taken by temporary safe holding the substructure by connecting holdback lines between substructure and installation barge bollards.Revisit OBS engineering study and analysisRevisit on bottom stability engineering study and lifting analysis considering changes to procedure/method by increasing the initial pile length (82m) to allow for early self-penetration.Revisit pile installation and sequenceThe piles have been re-fabricated onboard installation barge by utilizing the chaser rack at DB portside.The chaser rack was fabricated at site with available surplus material onboard DB. Once the revised pile fabrication completed, the piles were installed into the substructure leg for self-penetration.Result of Remediation WorkAfter successfully securing the substructure by installing the 82m pile length at one (1) leg of substructure, it has resulted that the substructure OBS has been improved to allow the COMPANY to proceed with original installation plan sequence as per installation procedure. Ultimately, COMPANY has managed to avoid catastrophic event. Despite all the challenges, the installation of LWS were completed successfully, no damage to property and most importantly with Zero Lost Time Injury (LTI).

Abstract:
The Exo-Skeletal Engine concept represents a new radical engine technology with the potential for a substantial revolution in engine design. It is an all composite drum rotor engine in which conventional heavy shafts and discs are eliminated and are replaced by rotating casings that support the blades in spanwise compression. Thus the rotating blades are in compression rather than in tension. The resulting open channel at the engine centerline has immense potential for jet noise reduction, and can also accommodate an inner combined-cycle thruster such as a ramjet. The Exo-Skeletal Engine is described in some detail with respect to geometry, components and potential benefits. Initial evaluation, results for drum rotors, bearings and weights are summarized. Component configuration, assembly plan and potential fabrication processes are also identified. A finite element model of the assembled engine and its major components are described. Preliminary results obtained thus far show at least 30 percent reduction of engine weight and about 10 db noise reduction, compared to a baseline conventional high bypass-ratio engine. Potential benefits in all aspects of engine technology are identified and tabulated. Quantitative assessments of potential benefits are in progress.

Abstract:
GE and NAVAIR are working together to find and develop practical techniques to reduce jet noise on legacy tactical aircraft such as the F/A-18. Noise is an important issue for the Navy that has grown dramatically over the last number of years. The two most important issues are the hearing loss induced during operations of these aircraft on aircraft carriers and the impact to communities around Naval Air Bases and training sites. A near term noise reduction goal of 3 dB has been established by NAVAIR as the first step in a much longer term plan to significantly reduce the noise felt in both of these situations. A near term solution for noise reduction implies that it can be implemented in the existing fleet with relatively little impact to the current air vehicle and the way it is operated, deployed, maintained, and funded. These constraints quickly limit the magnitude and types of changes that can be made to legacy engines or exhaust systems. In 2009, a static acoustic test on an F404 engine demonstrated that chevrons are equally effective at reducing noise all the way to full afterburner conditions. This test also measured thrust and the chevrons were demonstrated to result in very minimal performance impact at sea level static conditions. These two results are very important, as this was the first demonstration at full scale of practical noise reduction at afterburner conditions with minimal thrust impact. This paper will report on this latest test.

Abstract:
The goal of this research was to provide a better understanding of the interface between root-knot nematodes, Meloidogyne spp., and their host in order to develop rational targets for plantibodies and other novel methods of nematode control directed against the nematode surface coat (SC). Specific objectives were: 1. To produce additional monoclonal SC antibodies for use in Objectives 2, 3, and 4 and as candidates for development of plantibodies. 2. To determine the production and distribution of SC proteins during the infection process. 3. To use biochemical and immunological methods to perturbate the root-knot nematode SC in order to identify SC components that will serve as targets for rationally designed plantibodies. 4. To develop SC-mutant nematodes as additional tools for defining the role of the SC during infection. The external cuticular layer of nematodes is the epicuticle. In many nematodes, it is covered by a fuzzy material termed "surface coat" (SC). Since the SC is the outermost layer, it may playa role in the interaction between the nematode and its surroundings during all life stages in soil and during pathogenesis. The SC is composed mainly of proteins, carbohydrates (which can be part of glycoproteins), and lipids. SC proteins and glycoproteins have been labeled and extracted from preparasitic second-stage juveniles and adult females of Meloidogyne and specific antibodies have been raised against surface antigens. Antibodies can be used to gain more information about surface function and to isolate genes encoding for surface antigens. Characterization of surface antigens and their roles in different life-stages may be an important step towards the development of alternative control. Nevertheless, the role of the plant- parasitic nematode's surface in plant-nematode interaction is still not understood. Carbohydrates or carbohydrate-recognition domains (CROs) on the nematode surface may interact with CROs or carbohydrate molecules, on root surfaces or exudates, or be active after the nematode has penetrated into the root. Surface antigens undoubtedly play an important role in interactions with microorganisms that adhere to the nematodes. Polyclonal (PC) and monoclonal (MC) antibodies raised against Meloidogyne javanica, M. incognita and other plant-parasitic nematodes, were used to characterize the surface coat and secreted-excreted products of M. javanica and M. incognita. Some of the MC and PC antibodies raised against M. incognita showed cross-reactivity with the surface coat of M. javanica. Further characterization, in planta, of the epitopes recognized by the antibodies, showed that they were present in the parasitic juvenile stages and that the surface coat is shed during root penetration by the nematode and its migration between root cells. At the molecular level, we have followed two lines of experimentation. The first has been to identify genes encoding surface coat (SC) molecules, and we have isolated and characterized a small family of mucin genes from M. incognita. Our second approach has been to study host genes that respond to the nematode, and in particular, to the SC. Our previous work has identified a large suite of genes expressed in Lycopersicon esculentum giant cells, including the partial cDNA clone DB#131, which encodes a serine/threonine protein kinase. Isolation and predicted translation of the mature cDNA revealed a frame shift mutation in the translated region of nematode sensitive plants. By using primers homologous to conserved region of DB#131 we have identified the orthologues from three (nematode-resistant) Lycopersicon peruvianum strains and found that these plants lacked the mutation.

Abstract:
As a student undertaking a Longitudinal Integrated Clerkship (LIC)1 based in a GP practice in a rural community in the North of Scotland, I have been lucky to be given responsibility and my own clinic lists. Every day I conduct consultations that change my practice: the challenge of clinically applying the theory I have studied, controlling a consultation and efficiently exploring a patient's problems, empathising with and empowering them to play a part in their own care2 – and most difficult I feel – dealing with the vast amount of uncertainty that medicine, and particularly primary care, presents to both clinician and patient. I initially consulted with a lady in her 60s who attended with her husband, complaining of severe lower back pain who was very difficult to assess due to her pain level. Her husband was understandably concerned about the degree of pain she was in. After assessment and discussion with one of the GPs, we agreed some pain relief and a physio assessment in the next few days would be a practical plan. The patient had one red flag, some leg weakness and numbness, which was her ‘normal’ on account of her multiple sclerosis. At the physio assessment a few days later, the physio felt things were worse and some urgent bloods were ordered, unfortunately finding raised cancer and inflammatory markers. A CT scan of the lung found widespread cancer, a later CT of the head after some developing some acute confusion found brain metastases, and a week and a half after presenting to me, the patient sadly died in hospital. While that was all impactful enough on me, it was the follow-up appointment with the husband who attended on the last triage slot of the evening two weeks later that I found completely altered my understanding of grief and the mourning of a loved one. The husband had asked to speak to a Andrew MacFarlane Year 3 ScotGEM Medical Student 2 doctor just to talk about what had happened to his wife. The GP decided that it would be better if he came into the practice - strictly he probably should have been consulted with over the phone due to coronavirus restrictions - but he was asked what he would prefer and he opted to come in. I sat in on the consultation, I had been helping with any examinations the triage doctor needed and I recognised that this was the husband of the lady I had seen a few weeks earlier. He came in and sat down, head lowered, hands fiddling with the zip on his jacket, trying to find what to say. The GP sat, turned so that they were opposite each other with no desk between them - I was seated off to the side, an onlooker, but acknowledged by the patient with a kind nod when he entered the room. The GP asked gently, “How are you doing?” and roughly 30 seconds passed (a long time in a conversation) before the patient spoke. “I just really miss her…” he whispered with great effort, “I don’t understand how this all happened.” Over the next 45 minutes, he spoke about his wife, how much pain she had been in, the rapid deterioration he witnessed, the cancer being found, and cruelly how she had passed away after he had gone home to get some rest after being by her bedside all day in the hospital. He talked about how they had met, how much he missed her, how empty the house felt without her, and asking himself and us how he was meant to move forward with his life. He had a lot of questions for us, and for himself. Had we missed anything – had he missed anything? The GP really just listened for almost the whole consultation, speaking to him gently, reassuring him that this wasn’t his or anyone’s fault. She stated that this was an awful time for him and that what he was feeling was entirely normal and something we will all universally go through. She emphasised that while it wasn’t helpful at the moment, that things would get better over time.3 He was really glad I was there – having shared a consultation with his wife and I – he thanked me emphatically even though I felt like I hadn’t really helped at all. After some tears, frequent moments of silence and a lot of questions, he left having gotten a lot off his chest. “You just have to listen to people, be there for them as they go through things, and answer their questions as best you can” urged my GP as we discussed the case when the patient left. Almost all family caregivers contact their GP with regards to grief and this consultation really made me realise how important an aspect of my practice it will be in the future.4 It has also made me reflect on the emphasis on undergraduate teaching around ‘breaking bad news’ to patients, but nothing taught about when patients are in the process of grieving further down the line.5 The skill Andrew MacFarlane Year 3 ScotGEM Medical Student 3 required to manage a grieving patient is not one limited to general practice. Patients may grieve the loss of function from acute trauma through to chronic illness in all specialties of medicine - in addition to ‘traditional’ grief from loss of family or friends.6 There wasn’t anything ‘medical’ in the consultation, but I came away from it with a real sense of purpose as to why this career is such a privilege. We look after patients so they can spend as much quality time as they are given with their loved ones, and their loved ones are the ones we care for after they are gone. We as doctors are the constant, and we have to meet patients with compassion at their most difficult times – because it is as much a part of the job as the knowledge and the science – and it is the part of us that patients will remember long after they leave our clinic room.
