A high-value, low-cost bubble continuous positive airway pressure system for low-resource settings:technical assessment and initial case reports

Acute respiratory infections are the leading cause of global child mortality. In the developing world, nasal oxygen therapy is often the only treatment option for babies who are suffering from respiratory distress. Without the added pressure of bubble Continuous Positive Airway Pressure (bCPAP) which helps maintain alveoli open, babies struggle to breathe and can suffer serious complications, and frequently death. A stand-alone bCPAP device can cost $6,000, too expensive for most developing world hospitals. Here, we describe the design and technical evaluation of a new, rugged bCPAP system that can be made in small volume for a cost-of-goods of approximately $350. Moreover, because of its simple design--consumer-grade pumps, medical tubing, and regulators--it requires only the simple replacement of a <$1 diaphragm approximately every 2 years for maintenance. The low-cost bCPAP device delivers pressure and flow equivalent to those of a reference bCPAP system used in the developed world. We describe the initial clinical cases of a child with bronchiolitis and a neonate with respiratory distress who were treated successfully with the new bCPAP device.

Parent Prediction of Autism Spectrum Disorder in Infants At Risk: A Follow-up Study

Later-born siblings of children with autism spectrum disorder (ASD) are considered at biological risk for ASD and the broader autism phenotype. Early screening may detect early signs of ASD and facilitate intervention as soon as possible. This follow-up study revisits and re-examines a second-degree autism screener for children at biological risk of autism, the Parent Observation Early Markers Scale (POEMS, Feldman et al., 2012). Using available follow-up information, 110 children (the original 108 infants plus 2 infants recruited after the completion of the original study) were divided into three groups: diagnosed group (n = 13), lost diagnosis group (n = 5), and undiagnosed group (n = 92). The POEMS continued to show acceptable predictive validity. The POEMS total scores and mean number of elevated items were significantly higher in the diagnosed group than the undiagnosed group. The lost diagnosis group did not differ from the undiagnosed group on POEMS total scores and elevated items at any age, but the lost diagnosis group had significantly lower total scores and number of elevated items than the diagnosed group starting at 18 months. Both ASD core and subsidiary behaviours differentiated the diagnosed and undiagnosed groups from 9−36 months of age. Using 70 as a cut-off score, sensitivity, specificity, and positive predictive value (PPV) were .69, .84, and .38, respectively. The study provides further evidence that the POEMS may serve as a low-cost early screener for ASD in at risk children and pinpoint specific developmental and behavioural problems that may be amenable to very early intervention.

La réponse au Farnésol de Candida albicans : production de biofilms et Parenté génétique

C. albicans est une levure pathogène opportuniste. Elle est un agent causal fréquent des infections muco-cutanées. C. albicans peut alterner entre la forme blastospore et mycélium. Cette dernière forme est impliquée dans la formation des biofilms. Le dimorphisme de C. albicans est contrôlé en partie par le phénomène de perception du quorum (quorum sensing) qui en autre, est associé à la molécule farnésol, produit par cette levure. La présence de cette molécule, inhibe la formation d’hyphe par C. albicans et par conséquent limite la formation de biofilms. Certaines souches ne répondent pas au farnésol et nous avons vérifié les hypothèses que : 1) la proportion des Non-Répondeurs (NR) au farnésol est similaire entre les souches de provenance orale et vaginale; 2) la capacité de formation de biofilm varie d’une souche à une autre mais les Non-Répondeurs en produisent en plus grande quantité; 3) la technique RAPD-PCR permettra de regrouper les souches de cette levure suivant leur provenance, leur capacité de formation de biofilm et leur aptitude à répondre au farnésol. La découverte d’une souche vaginale Non-Répondeur nous permet de croire que la proportion de ces souches est similaire entre les deux types de provenance. Les souches caractérisées Non-Répondeurs produisent 30 % plus de biofilm que les Répondeurs en absence de farnésol exogène dans le milieu. En présence de farnésol exogène, les Non-Répondeurs produisent 70 % plus de biomasse que les Répondeurs. De plus, la technique RAPD ne nous a pas permis de classer nos souches d’après les caractéristiques proposées. En conclusion, les souches orales de C. albicans semblent produire en moyenne plus de biomasse que les souches vaginales. Aussi, les NR semblent moins affectés par la présence du farnésol, ce qui pourrait causer la présence de biofilms tenaces. Les amorces utilisées pour la technique RAPD n’ont pas été efficace à la classification des souches dépendamment de leur provenance, de leur capacité à former un biofilm et à répondre au farnésol. Mots clés : Candida albicans, biofilm, perception du quorum (quorum sensing), farnésol, Non-Répondeur

Le "métier" de parent : au-delà des compétences et des performances

Les livres et programmes sur la petite-enfance se multiplient et, de plus en plus, l’accent est mis autant par les experts que l’État sur les premières années de la vie de l’enfant. Le regard semble davantage posé sur les compétences des parents pour privilégier le développement cognitif et moteur de leur progéniture, avec l’objectif de pouvoir éviter à cette dernière des trajectoires considérées comme « déviantes ». Ce regard atteint cependant différemment les parents d’une même société. Alors qu’il s’adresse à un groupe restreint de parents ne stimulant peut-être pas assez leurs enfants de la manière promulguée par l’État, certains auteurs mettent de l’avant une tendance d’autres parents à surstimuler leur enfant (Corwin, 2006; Guthrie et Matthews, 2002; Duclos, 2006; Proulx, 2004; Elkind, 1983; Honoré, 2008; Rosenfeld et Wise, 2000). Pour d’autres encore, cette injonction de « produire » un enfant « compétent » s’ajoute à des stress déjà présents tels que la pauvreté ou la pression au travail. La tendance à surstimuler, surprogrammer ou surautonomiser les enfants dans le but de « produire » des enfants « compétents » est qualifiée d’hyper-parentage, de parentage excessif ou de surparentage et n’est pas sans rappeler la course à la performance étudiée pour les adultes par Ehrenberg (2001[1991]) ou de Gaulejac (2005). En suivant ce dernier auteur ou Perrenoud (2008), pour qui la tendance à gérer la famille comme une entreprise proviendrait d’une « contagion » du monde du travail, cette recherche porte sur le lien entre la manière dont les parents envisagent le cheminement de leur enfant et leur propre expérience de travail, en comparaison avec les discours des experts et de l’État.

Salinity-induced changes in the microbial use of sugarcane filter cake added to soil

Five laboratory incubation experiments were carried out to assess the salinity-induced changes in the microbial use of sugarcane filter cake added to soil. The first laboratory experiment was carried out to prove the hypothesis that the lower content of fungal biomass in a saline soil reduces the decomposition of a complex organic substrate in comparison to a non-saline soil under acidic conditions. Three different rates (0.5, 1.0, and 2.0%) of sugarcane filter cake were added to both soils and incubated for 63 days at 30°C. In the saline control soil without amendment, cumulative CO2 production was 70% greater than in the corresponding non-saline control soil, but the formation of inorganic N did not differ between these two soils. However, nitrification was inhibited in the saline soil. The increase in cumulative CO2 production by adding filter cake was similar in both soils, corresponding to 29% of the filter cake C at all three addition rates. Also the increases in microbial biomass C and biomass N were linearly related to the amount of filter cake added, but this increase was slightly higher for both properties in the saline soil. In contrast to microbial biomass, the absolute increase in ergosterol content in the saline soil was on average only half that in the non-saline soil and it showed also strong temporal changes during the incubation: A strong initial increase after adding the filter cake was followed by a rapid decline. The addition of filter cake led to immobilisation of inorganic N in both soils. This immobilisation was not expected, because the total C-to-total N ratio of the filter cake was below 13 and the organic C-to-organic N ratio in the 0.5 M K2SO4 extract of this material was even lower at 9.2. The immobilisation was considerably higher in the saline soil than in the non-saline soil. The N immobilisation capacity of sugarcane filter cake should be considered when this material is applied to arable sites at high rations. The second incubation experiment was carried out to examine the N immobilizing effect of sugarcane filter cake (C/N ratio of 12.4) and to investigate whether mixing it with compost (C/N ratio of 10.5) has any synergistic effects on C and N mineralization after incorporation into the soil. Approximately 19% of the compost C added and 37% of the filter cake C were evolved as CO2, assuming that the amendments had no effects on the decomposition of soil organic C. However, only 28% of the added filter cake was lost according to the total C and d13C values. Filter cake and compost contained initially significant concentrations of inorganic N, which was nearly completely immobilized between day 7 and 14 of the incubation in most cases. After day 14, N re-mineralization occurred at an average rate of 0.73 µg N g-1 soil d-1 in most amendment treatments, paralleling the N mineralization rate of the non-amended control without significant difference. No significant net N mineralization from the amendment N occurred in any of the amendment treatments in comparison to the control. The addition of compost and filter cake resulted in a linear increase in microbial biomass C with increasing amounts of C added. This increase was not affected by differences in substrate quality, especially the three times larger content of K2SO4 extractable organic C in the sugarcane filter cake. In most amendment treatments, microbial biomass C and biomass N increased until the end of the incubation. No synergistic effects could be observed in the mixture treatments of compost and sugarcane filter cake. The third 42-day incubation experiment was conducted to answer the questions whether the decomposition of sugarcane filter cake also result in immobilization of nitrogen in a saline alkaline soil and whether the mixing of sugarcane filter cake with glucose (adjusted to a C/N ratio of 12.5 with (NH4)2SO4) change its decomposition. The relative percentage CO2 evolved increased from 35% of the added C in the pure 0.5% filter cake treatment to 41% in the 0.5% filter cake +0.25% glucose treatment to 48% in the 0.5% filter cake +0.5% glucose treatment. The three different amendment treatments led to immediate increases in microbial biomass C and biomass N within 6 h that persisted only in the pure filter cake treatment until the end of the incubation. The fungal cell-membrane component ergosterol showed initially an over-proportionate increase in relation to microbial biomass C that fully disappeared at the end of the incubation. The cellulase activity showed a 5-fold increase after filter cake addition, which was not further increased by the additional glucose amendment. The cellulase activity showed an exponential decline to values around 4% of the initial value in all treatments. The amount of inorganic N immobilized from day 0 to day 14 increased with increasing amount of C added in comparison to the control treatment. Since day 14, the immobilized N was re-mineralized at rates between 1.31 and 1.51 µg N g-1 soil d-1 in the amendment treatments and was thus more than doubled in comparison with the control treatment. This means that the re-mineralization rate is independent from the actual size of the microbial residues pool and also independent from the size of the soil microbial biomass. Other unknown soil properties seem to form a soil-specific gate for the release of inorganic N. The fourth incubation experiment was carried out with the objective of assessing the effects of salt additions containing different anions (Cl-, SO42-, HCO3-) on the microbial use of sugarcane filter cake and dhancha leaves amended to inoculated sterile quartz sand. In the subsequent fifth experiment, the objective was to assess the effects of inoculum and temperature on the decomposition of sugar cane filter cake. In the fourth experiment, sugarcane filter cake led to significantly lower respiration rates, lower contents of extractable C and N, and lower contents of microbial biomass C and N than dhancha leaves, but to a higher respiratory quotient RQ and to a higher content of the fungal biomarker ergosterol. The RQ was significantly increased after salt addition, when comparing the average of all salinity treatments with the control. Differences in anion composition had no clear effects on the RQ values. In experiment 2, the rise in temperature from 20 to 40°C increased the CO2 production rate by a factor of 1.6, the O2 consumption rate by a factor of 1.9 and the ergosterol content by 60%. In contrast, the contents of microbial biomass N decreased by 60% and the RQ by 13%. The effects of the inoculation with a saline soil were in most cases negative and did not indicate a better adaptation of these organisms to salinity. The general effects of anion composition on microbial biomass and activity indices were small and inconsistent. Only the fraction of 0.5 M K2SO4 extractable C and N in non-fumigated soil was consistently increased in the 1.2 M NaHCO3 treatment of both experiments. In contrast to the small salinity effects, the quality of the substrate has overwhelming effects on microbial biomass and activity indices, especially on the fungal part of the microbial community.

Measuring Value in Product Development

“What is value in product development?” is the key question of this paper. The answer is critical to the creation of lean in product development. By knowing how much value is added by product development (PD) activities, decisions can be more rationally made about how to allocate resources, such as time and money.

Measuring Value in Product Development

“What is value in product development?” is the key question of this paper. The answer is critical to the creation of lean in product development. By knowing how much value is added by product development (PD) activities, decisions can be more rationally made about how to allocate resources, such as time and money. In order to apply the principles of Lean Thinking and remove waste from the product development system, value must be precisely defined. Unfortunately, value is a complex entity that is composed of many dimensions and has thus far eluded definition on a local level. For this reason, research has been initiated on “Measuring Value in Product Development.” This paper serves as an introduction to this research. It presents the current understanding of value in PD, the critical questions involved, and a specific research design to guide the development of a methodology for measuring value. Work in PD value currently focuses on either high-level perspectives on value, or detailed looks at the attributes that value might have locally in the PD process. Models that attempt to capture value in PD are reviewed. These methods, however, do not capture the depth necessary to allow for application. A methodology is needed to evaluate activities on a local level to determine the amount of value they add and their sensitivity with respect to performance, cost, time, and risk. Two conceptual tools are proposed. The first is a conceptual framework for value creation in PD, referred to here as the Value Creation Model. The second tool is the Value-Activity Map, which shows the relationships between specific activities and value attributes. These maps will allow a better understanding of the development of value in PD, will facilitate comparison of value development between separate projects, and will provide the information necessary to adapt process analysis tools (such as DSM) to consider value. The key questions that this research entails are: · What are the primary attributes of lifecycle value within PD? · How can one model the creation of value in a specific PD process? · Can a useful methodology be developed to quantify value in PD processes? · What are the tools necessary for application? · What PD metrics will be integrated with the necessary tools? The research milestones are: · Collection of value attributes and activities (September, 200) · Development of methodology of value-activity association (October, 2000) · Testing and refinement of the methodology (January, 2001) · Tool Development (March, 2001) · Present findings at July INCOSE conference (April, 2001) · Deliver thesis that captures a formalized methodology for defining value in PD (including LEM data sheets) (June, 2001) The research design aims for the development of two primary deliverables: a methodology to guide the incorporation of value, and a product development tool that will allow direct application.

Producció i caracterització de variants de la ribonucleasa pancreàtica humana dissenyades per a adquirir propietats citotòxiques

Amb la finalitat d'aprofundir en les bases moleculars de la citotoxicitat de les ribonucleases pancreàtiques, es van construir variants derivades de l'HP-RNasa seguint dues estratègies. En la primera, es van generar variants de l'enzim resistents a l'acció de l'inhibidor proteic de les ribonucleases (hRI), substituint residus implicats en la interfície de contacte entre la ribonucleasa i l'hRI. En la segona, es va addicionar el motiu RGD en regions de superfície de la proteïna implicades en la formació del complex amb l'hRI, a fi de promoure la seva interacció amb la membrana plasmàtica de les cèl·lules i a la vegada disminuir l'afinitat de les variants per l'hRI. Es va comprovar que només les variants portadores de substitucions múltiples adquirien la capacitat de resistència a l'hRI. L'estudi del percentatge d'inhibició de la síntesi proteica en cèl·lules incubades amb cadascuna de les variants va mostrar que només dues de les variants construïdes havien adquirit propietats citotòxiques. La citotoxicitat més elevada la va presentar una variant que no era resistent a l'hRI, amb valors que eren només entre 5 i 15 vegades inferiors als de l'onconasa. Aquest resultat demostrà que la sensibilitat a l'hRI no és necessàriament un paràmetre limitant per a la citotoxicitat de les ribonucleases. Cap de les variants que incorporava un motiu RGD presentà citotoxicitat, evidenciant que aquest motiu no és efectiu a fi de dotar les ribonucleases pancreàtiques de propietats citotòxiques. Es van estudiar les bases moleculars de la citotoxicitat de la variant més citotòxica. En primer lloc, l'anàlisi de la internalització per marcatge radioactiu d'aquesta variant en relació amb l'onconasa i amb altres variants de l'HP-RNasa no citotòxiques, va posar en evidència que només l'onconasa era internalitzada eficientment. Es descartava així la possibilitat que l'acció citotòxica de l'enzim estudiat fos conseqüència d'una major eficiència d'endocitosi. També es va comprovar que l'addició del motiu RGD no era capaç de promoure la internalització de les proteïnes amb més eficàcia. Per microscòpia confocal de fluorescència, les variants humanes només es van començar a detectar a l'interior de la cèl·lula a partir de les 24 h d'incubació. Totes les variants generades van presentar una eficiència catalítica superior al 50 % de l'activitat de la seva proteïna parental, PM5, indicant que probablement l'estructura del centre actiu no havia estat afectada de manera dràstica per les substitucions introduïdes. No obstant, en tots els casos es va produir una disminució en la termoestabilitat respecte a PM5. Aquest resultat indicà que la correlació descrita a la bibliografia entre l'increment de termoestabilitat i l'increment de citotoxicitat per les ribonucleases no sempre es compleix. Per microscòpia confocal es va comprovar que tant la proteïna més citotòxica, com una variant no citotòxica resistent a l'hRI, així com la proteïna parental, seguien la via de degradació lisosomal. Aquesta ruta de trànsit no va ser afectada per l'addició de drogues que alteren les vies de trànsit retrògrad (monensina i brefeldina A), però sí per l'addició de la bafilomicina A1, una droga que neutralitza el pH endosomal i que va actuar alentint el trànsit de les proteïnes als lisosomes. D'acord amb aquests resultats, els valors de citotoxicitat de les variants es van incrementar de manera significativa només en presència de bafilomicina A1, suggerint que les ribonucleases transloquen al citoplasma a partir d'algun punt de la via de trànsit endosomal. Es va comprovar que l'acció de la variant més citotòxica era deguda a que l'addició d'un segon motiu de tres Arg en PE5 dota a aquesta proteïna amb un senyal de transport nuclear. La fracció d'enzim que aconsegueix translocar al citoplasma a partir d'algun punt de la via endosomal previ als lisosomes, és conduït ràpidament al nucli de la cèl·lula per mitjà del mecanisme clàssic de transport actiu. Per la seva afinitat amb l'rRNA, l'enzim es concentra en el nuclèol, on probablement duu a terme la seva activitat catalítica. La interacció d'aquesta variant amb els receptors nucleocitoplasmàtics, les importines, impediria per altra banda el bloqueig de l'enzim per part de l'hRI. Els resultats obtinguts presenten una nova estratègia de disseny de ribonucleases citotòxiques, basada en l'addició de segments NLS a fi de promoure el transport nuclear dels enzims. Aquesta estratègia podria permetre superar limitacions que fins al moment han estat descrites com a limitants de la citotoxicitat de les ribonucleases pancreàtiques, com la sensibilitat a l'hRI o la baixa eficiència d'internalització.

Living up to the value agenda: the empirical realities of through-life value creation in construction

Current research agendas are increasingly encouraging the construction industry to operate on the basis of 'added value'. Such debates echo the established concept of 'high value manufacturing' and associated trends towards servitization. Within construction, the so-called 'value agenda' draws heavily from the notion of integrated solutions. This is held to be especially appropriate in the context of PFI projects. Also relevant is the concept of service-led projects whereby the project rationale is driven by the client's objectives for delivering an enhanced service to its own customers. Such ideas are contextualized by a consideration of broader trends of privatization and outsourcing within and across the construction industry's client base. The current emphasis on integrated solutions reflects long-term trends within privatized client organizations towards the outsourcing of asset management capabilities. However, such trends are by no means uniform or consistent. An in-depth case study of three operating divisions within a major construction company illustrates that firms are unlikely to reorientate their business in response to the 'value agenda'. In the case of PFI, the tendency has been to establish specialist units for the purposes of winning work. Meanwhile, institutionally embedded operating routines within the rest of the business remain broadly unaffected.

Future directions for doll play narrative research: a commentary

Past research into doll play narratives has been productive in elucidating children's inner experiences, their determinants, and their role in child behaviour problems. The current volume takes this work forward in several directions: first, it indicates the value of designing story stems and coding schemes to address more specific questions about the developmental process of specific syndromes. Second, contributions demonstrate the "added value" provided by children's narratives, over and above information derived from other sources. Third, this recent research enhances our understanding of the role of parental representations and states of mind in influencing children's narratives; how these may come to influence child functioning via co-constructed parent-child dialogues is an important area for future research. Finally, possibilities of extending the clinical utility of doll play narratives are explored.

Achieving whole-life value: The challenges of service-led construction

Major construction clients are increasingly looking to procure built facilities on the basis of added value, rather than capital cost. Recent advances in the procurement of construction projects have emphasised a whole-life value approach to meeting the client’s objectives, with strategies put in place to encourage long-term commitment and through-life service provision. Construction firms are therefore increasingly required to take on responsibility for the operation and maintenance of the construction project on the client’s behalf - with the emphasis on value and service. This inevitably throws up a host of challenges, not the least of which is the need for construction firms to manage and accommodate the new emphasis on service. Indeed, these ‘service-led’ projects represent a new realm of construction projects where the rationale for the project is driven by client’s objectives with some aspect of service provision. This vision of downstream service delivery increases the number of stakeholders, adds to project complexity and challenges deeply-ingrained working practices. Ultimately it presents a major challenge for the construction sector. This paper sets out to unravel some of the many implications that this change brings with it. It draws upon ongoing research investigating how construction firms can adapt to a more service-orientated built environment and add value in project-based environments. The conclusions lay bare the challenges that firms face when trying to compete on the basis of added-value and service delivery. In particular, how it affects deeply-ingrained working practices and established relationships in the sector.

Does active management add any value?

The question as to whether active management adds any value above that of the funds investment policy is one of continual interest to investors. In order to investigate this issue in the UK real estate market we examine a number of related questions. First, how much return variability is explained by investment policy? Second, how similar are the policies across funds? Third, how much of a fund’s return is determined by investment policy? Finally, how was this added value achieved? Using data for 19 real estate funds we find that investment policy explains less than half of the variability in returns over time, nothing of the variation across funds and that more than 100% of a level of return is attributed to investment policy. The results also show UK real estate fund focus exclusively on trying to pick winners to add value and that in pursuit of active return fund mangers incur high tracking error risk, consequently, successful active management is very difficult to achieve. In addition, the results are dependent on the benchmark used to represent the investment policy of the fund. Nonetheless, active management can indeed add value to a real estate funds performance. This is the good news. The bad news is adding value is much more difficult to achieve than is generally accepted.

Development and validation of a parent report measure for detection of cognitive delay in infancy

Aim To develop a brief, parent-completed instrument (‘ERIC’) for detection of cognitive delay in 10-24 month-olds born preterm, or with low birth weight, or with perinatal complications, and to establish its diagnostic properties. Method Scores were collected from parents of 317 children meeting ≥1 inclusion criteria (birth weight <1500g; gestational age <34 completed weeks; 5-minute Apgar <7; presence of hypoxic-ischemic encephalopathy) and meeting no exclusion criteria. Children were assessed for cognitive delay using a criterion score on the Bayley Scales of Infant and Toddler Development Cognitive Scale III1 <80. Items were retained according to their individual associations with delay. Sensitivity, specificity, Positive and Negative Predictive Values were estimated and a truncated ERIC was developed for use <14 months. Results ERIC detected 17 out of 18 delayed children in the sample, with 94.4% sensitivity (95% CI [confidence interval] 83.9-100%), 76.9% specificity (72.1-81.7%), 19.8% positive predictive value (11.4-28.2%); 99.6% negative predictive value (98.7-100%); 4.09 likelihood ratio positive; and 0.07 likelihood ratio negative; the associated Area under the Curve was .909 (.829-.960). Interpretation ERIC has potential value as a quickly-administered diagnostic instrument for the absence of early cognitive delay in preterm or premature infants of 10-24 months, and as a screen for cognitive delay. Further research may be needed before ERIC can be recommended for wide-scale use.

Is communication guidance mistaken? Qualitative study of parent-oncologist communication in childhood cancer

background: Guidance encourages oncologists to engage patients and relatives in discussing the emotions that accompany cancer diagnosis and treatment. We investigated the perspectives of parents of children with leukaemia on the role of paediatric oncologists in such discussion. methods: Qualitative study comprising 33 audio-recorded parent–oncologist consultations and semi-structured interviews with 67 parents during the year following diagnosis. results: Consultations soon after the diagnosis were largely devoid of overt discussion of parental emotion. Interviewed parents did not describe a need for such discussion. They spoke of being comforted by oncologists’ clinical focus, by the biomedical information they provided and by their calmness and constancy. When we explicitly asked parents 1 year later about the oncologists’ role in emotional support, they overwhelmingly told us that they did not want to discuss their feelings with oncologists. They wanted to preserve the oncologists’ focus on their child’s clinical care, deprecated anything that diverted from this and spoke of the value of boundaries in the parent–oncologist relationship. conclusion: Parents were usually comforted by oncologists, but this was not achieved in the way suggested by communication guidance. Communication guidance would benefit from an enhanced understanding of how emotional support is experienced by those who rely on it.
