The purpose of this study is to investigate the preparedness at the prehospital emergency care unit in north-western Skåne. Measuring preparedness is important to ensure that the ability to respond on emergency calls is satisfactory. To do this for north-western Skåne historical data from 2015 was extracted from SOS Alarm’s database. It was used to calculate preparedness using workload and coverage as measurements. The workload was calculated by taking the busy periods and comparing them to the ambulances working times. The coverage was calculated by defining neighbouring stations to cover for each station and then finding the amount of hours when there was no ambulance at either station. These calculations show that two of the six stations in north-western Skåne are in need of improvement. To increase the preparedness to a good level resources will have to be added at the liable stations. These resources would be new ambulances. There is a possibility to relocate ambulances from stations within the district but that would lead to a worsened preparedness for the stations which these ambulances belonged to in the first place.

Syftet med denna uppsats var att genom ett salutogent perspektiv få en ökad förståelse för, inom äldreomsorgen verksamma, biståndshandläggares arbetssituation samt att undersöka vad som kan bidra till att biståndshandläggares arbetssituation upplevs som lättare och mindre påfrestande. Metoden som använts är kvalitativa intervjuer där sex biståndshandläggare verksamma i Värmland har intervjuats. Intervjuerna analyserades genom teman ur KASAM och resulterade i kategorier under varje tema. Under temat begriplighet framkom att biståndshandläggare får stöd från sina kollegor men att de också önskar att det fanns mer resurser för handledning. Biståndshandläggare utför mer än vad som ingår i arbetsbeskrivningen. Under temat hanterbarhet framgår att hög arbetsbelastning hanteras genom att biståndshandläggarna måste planera, strukturera och prioritera. Kollegornas stöd gör arbetet lättare att hantera då de genom att prata med varandra bearbetar känslomässigt påfrestande delar av arbetet. De uttryckte olika behov av att reflektera över sitt arbete. Biståndshandläggare har en stor frihet att planera sin egen arbetsdag och de samverkar med andra professioner. Under temat meningsfullhet framgår att biståndshandläggare finner mening i att göra skillnad för den enskilde. Vårt resultat visar att biståndshandläggarna är utsatta för stress i sitt arbete och att de också har förmåga att möta stressen, men förmågan att möta stressen minskar när arbetsbelastningen blir för hög. / The purpose of this paper was to, by using a salutogenic perspective, achieve a better understanding of eldercare, care managers’ work situation and to explore which factors contribute to the administrator's job situation being experienced as easier and less stressful. The method used were qualitative interviews where six care managers active in Värmland were interviewed. The interviews were analyzed by themes from the Sence Of Coherense and led to categories under each theme. Under the theme comprehensibility was found that care managers receive support from their colleagues but they wish for more resources for professional guidance counselling. Care managers perform more duties than what is included in their job description. Under the theme manageability it shows how administrators have to manage their, high workloads by planning, structurizing and prioritizing. The work is easier to handle when they recieve support from colleagues by talking to each other about strenuous parts of the work. They expressed different needs to reflect on their work. Care managers have a freedom to plan their own and they do collaborate and interact with other professionals. Under the theme meaningfulness the results show that care managers find meaning when they make a difference for their clients. Our results show that care managers are exposed to stress in their work and that they have their own resources cope with. The ability to handle stress is reduced when they feel that the work load is too high.

Sick leave due to mental illness has increased dramatically in recent decades and is today one of the main reasons why individuals become long-term sick. Social workers job situation within social service has in recent years attracted an increasing attention and the debate has largely been about the high workload in the profession. Mental illness for social workers is a growing problem and there are no signs of a positive trend shift. The purpose of this study was to create a wider understanding of why social workers are prevented to work due to mental illness, goes on medical leave, and find out if it is possible to identify which common factors in these social workers stories. To answer the study's purpose, two issues have been considered. Partly which factors long-term sick social workers identified as the reason for their mental illness that led to long-term illness, and how the long-term sick social workers describe their individual experiences before, during and after their sick leave. The methodology has been a qualitative design where eight long-term sick social workers scattered around the country conducted interviews via e-mail through a semi-structured interview guide. The result will be divided and presented in three themes; Social workers practical work which concerns the social workers descriptions of their work place in the social services and the factors of the organization that has affected their work situation. It also presents the social workers perception of the impact of political decisions concerning the field of social work. The theme of social workers profession presents the results that have emerged and concerns how social workers perceive and identify their professional role. The third theme of individual experiences by social workers presents the results concerning the personal reflections that social workers have about themselves and their future role as a professional social worker. The study results show that job related factors largely affected the individual's mental health. It is clear that the structures upon an organisational level, the complexity of the professional role contra individual ideals have affected and led to the social workers present situation of long-term sick due to mental illness. The concluding section of this paper discusses several components with potential for development as possible contributing solutions to the problematic situation that made these social workers sick. Social work education, leadership and skills development are areas that are challenged in our discussion. / Sjukskrivning på grund av psykisk ohälsa har ökat drastiskt de senaste decennierna och är idag en av de främsta anledningarna till varför individer blir långtidssjukskrivna. Socialsekreterares arbetssituation har under de senaste åren uppmärksammats allt mer och debatten har till stor del kommit att handla om den höga arbetsbelastningen inom yrket. Psykisk ohälsa för socialsekreterare är ett växande problem och trenden tycks vara svår att bryta. Syftet med den här studien har varit att skapa en ökad förståelse kring varför socialsekreterare blivit sjukskrivna på grund av psykisk ohälsa samt ta reda på om det går att urskilja gemensamma faktorer i socialsekreterarnas berättelser. För att besvara studiens syfte har två frågeställningar varit aktuella. Dels vilka faktorer som sjukskrivna socialsekreterare identifierat föranlett deras psykiska ohälsa som lett till långtidssjukskrivning och dels hur långtidssjukskrivna socialsekreterare beskriver sina individuella upplevelser innan, under och efter sin sjukskrivning. Metodvalet har varit av kvalitativ design där åtta långtidssjukskrivna socialsekreterare spridda över hela landet genomförde intervjuer via mail genom en semistrukturerad intervjuguide. Resultatet delas upp och presenteras i tre teman; socialsekreterarens arbete som berör socialsekreterarnas beskrivning sin arbetsplats på socialtjänsten och de faktorer i organisationen som påverkat deras arbetssituation. Här presenteras även socialsekreterarnas bild av hur de ser på socialpolitikens påverkan av deras arbete. I temat socialsekreterarens yrkesroll presenteras de resultat som berör hur socialsekreterarna upplever och identifierar sin yrkesroll. I det tredje temat socialsekreterarens individuella upplevelser presenteras de resultat som berör de personliga reflektioner som socialsekreterarna har kring sig själva och sin framtida roll som yrkesverksam socialsekreterare. Studiens resultat visar att faktorer på arbetsplatsen i stor utsträckning påverkat individens psykiska ohälsa. Det framgår tydligt att organisatoriska strukturer, yrkesrollens komplexitet och individuella ideal har påverkat och föranlett att socialsekreterarna blivit långtidssjukskrivna på grund av psykisk ohälsa. I uppsatsens avslutande del diskuteras flera komponenter med utvecklingspotential som möjliga bidragande lösningar på den problematiska situationen som gjort dessa socialsekreterare sjuka. Socionomutbildningen, ledarskap och kompetensutveckling är områden som utmanas i vår diskussion.

The purpose of the study was to gain a greater understanding of how the amount of stress and workload that exists in Swedish social services affect the clients. The study was based on interviews with socialworkers responsible for childcustody enquiries. I chose to interview socialworkers in two different cities that resembled eachother. One of the interviews was individual and two was in focusgroups. The socialworkers were interviewed with a semi structured interview manual. The results showed that one of the cities social services, the socialworkers had a more difficult worksituation than the other city. The reason to why one city was more well functioning than the other depended on how the organization had handled the past years amount of workload. Both differences and similaritis was found. In the city that had a more difficult work situation the socialworkers had to prioritize with their time more and their clients were more affected than in the other city. Prioritizing time is something that was found in both cities but the city with more difficult worksituation had to prioritize more with their time and that lead to less time with their clients. It also lead to lower quality enquiries.

Thesis (MPhil)--University of Stellenbosch, 2001. / ENGLISH ABSTRACT: Change characterises life in the early twenty first century and higher education is no exception. Higher education in South Africa is currently in a considerable state of flux which ultimately is actualised at institutional level. It is academic staff who encounter these changes first hand. Technikon lecturers, in particular, are faced with additional challenges not faced by their university counterparts - they have been called upon to change from a primarily vocational to an academic alignment as a result of technikons being given the right to award degrees. This study conducts a cross sectional survey of academic staff at the Port Elizabeth Technikon to identify their academic workload, with particular reference to their research function. It also seeks to establish whether lecturers consider themselves to be adequately prepared for their research function. A review of the literature reveals that lecturers in higher education are involved in a wide variety of activities, the main ones being teaching, research, service, and scholarship. The literature review also shows that in overseas institutions with missions similar to the technikons, lecturers experienced changes to their workload as a result of the restructuring of higher education. The empirical study shows that academic staff at the Port Elizabeth Technikon have much in common with their international peers in terms of the changes and pressures that have been experienced. The work reality for lecturers at the named institution includes all the traditional elements associated with being academic: teaching, research, service and scholarship. Although research is a new function, this has been positively embraced by most staff and that in most cases lecturers consider themselves to be adequately prepared for this function. The empirical study also shows that more than one third of the respondents do not support the institutional vision of becoming "the first choice technological university of South Africa". Further, the study shows that, in common with other studies, staff were of the opinion that the institution undervalues teaching and that research attracts more recognition and rewards. Finally, it shows that significant numbers of staff work in excess of 50 hours per week and carry teaching loads that are greater than the institutional guidelines. Recommendations are made on the basis of these findings and a further avenue of research is suggested. / AFRIKAANSE OPSOMMING: Verandering is 'n kenmerk van die lewe in die vroee een-en-twintigste eeu en hoer onderwys is geen uitsondering nie. Hoer onderwys in Suid-Afrika ervaar tans 'n besonderse toe stand van veranderlikheid, maar dit is uiteindelik op onderwysinrigtingvlak wat did tot verwerkliking kom. Dit is akademiese personeel wat hierdie veranderings eerstehands ondervind. In die besonder word Technikonpersoneel gekonfronteer met uitdagings waaraan hulle universiteitsewekniee nie blootgestel word nie - daar word van hulle vereis om van 'n primere beroeps-orientering oor te skakel na 'n akademiese ingesteldheid as gevolg van die feit dat technikons die mandaat verkry het om grade toe te ken. Hierdie studie het 'n opname onder akademiese personeel aan die Port Elizabethse Technikon gedoen om vas te stel wat die personeel se akademiese werkslading is, met besondere verwysing na hulle navorsingsfunksie. Die ondersoek poog ook om vas te stel of lektore van mening is dat hulle genoegsaam voorberei is vir hulle navorsingsfunksie. 'n Literatuuroorsig toon dat lektore in hoer onderwys betrokke is by 'n bree verskeidenheid aktiwiteite, waarvan die belangrikste onderrig, navorsing, dienslewering en vakkundigheid (scholarship) is. Die literatuurstudie toon ook dat in ander lande aan inrigtings met soortgelyke doelstellings as die technikons, lektore veranderings in hulle werksladings ondervind het as gevolg van die herstrukturering van hoer onderwys wat teen die einde van die twintigste eeu plaasgevind het. Die empiriese studie toon dat akademiese personeel aan die Port Elizabethse Technikon met betrekking tot die veranderings en druk wat ondervind word veel in gemeen het met hulle intemasionale ewekniee, Die realiteit in die werkplek vir lektore by genoemde inrigting sluit al die tradisionele elemente in wat verband hou met die akademie: onderrig, navorsing, diens en vakkundigheid (scholarship). Alhoewel navorsing 'n nuwe funksie is, is dit deur die meerderheid personeel positief aanvaar en in die meeste gevalle is lektore van mening dat hulle vir hierdie funksie voldoende voorberei is. Die empiriese studie toon ook dat meer as een derde van die respondente nie die institusionele visie om "die eerste-keuse tegnologiese universiteit van Suid-Afrika te wees" ondersteun rue. Voorts toon die studie soos ook in ander studies, dat personeel van mening was dat die inrigting onderrig geringskat en dat meer erkenning en belonings aan navorsing gegee word. Laastens toon dit dat 'n beduidende aantal personeellede meer as 50 uur per week werk- en onderrigladings dra wat meer is as die riglyne van die inrigting. Op grond van hierdie bevindings word aanbevelings gemaak en 'n verdere navorsingsrigting voorgestel.

Emerging architecture designs include tens of processing cores on a single chip die; it is believed that the number of cores will reach the hundreds in not so many years from now. However, most common parallel workloads cannot fully utilize such systems. They expose fluctuating parallelism, and do not scale up indefinitely as there is usually a point after which synchronization costs outweigh the gains of parallelism. The combination of these issues suggests that large-scale systems will be either multiprogrammed or have their unneeded resources powered off.Multiprogramming leads to hardware resource contention and as a result application performance degradation, even when there are enough resources, due to negative share effects and increased bus traffic. Most often this degradation is quite unbalanced between co-runners, as some applications dominate the hardware over others. Current Operating Systems blindly provide applications with access to as many resources they ask for. This leads to over-committing the system with too many threads, memory contention and increased bus traffic. Due to the inability of the application to have any insight on system-wide resource demands, most parallel workloads will create as many threads as there are available cores. If every co-running application does the same, the system ends up with threads $N$ times the amount of cores. Threads then need to time-share cores, so the continuous context-switching and cache line evictions generate considerable overhead.This thesis proposes a novel solution across all software layers that achieves throughput optimization and uniform performance degradation of co-running applications. Through a novel fully automated approach (DVS and Palirria), task-parallel applications can accurately quantify their available parallelism online, generating a meaningful metric as parallelism feedback to the Operating System. A second component in the Operating System scheduler (Pond) uses such feedback from all co-runners to effectively partition available resources.The proposed two-level scheduling scheme ultimately achieves having each co-runner degrade its performance by the same factor, relative to how it would execute with unrestricted isolated access to the same hardware. We call this fair scheduling, departing from the traditional notion of equal opportunity which causes uneven degradation, with some experiments showing at least one application degrading its performance 10 times less than its co-runners. / <p>QC 20151016</p>

We report on initial research on the concurrency control issue of compiled database applications. Such applications have a repository style of architecture in which a collection of software modules operate on a common database in terms of a set of predefined transaction types, an architectural view that is useful for the deployment of database technology to embedded control programs. We focus on decoupling concurrency control from any functionality relating to recovery. Such decoupling facilitates the compile-time query optimization. <br /><br /> Because it is the possibility of transaction aborts for deadlock resolution that makes the recovery subsystem necessary, we choose the deadlock-free tree locking (TL) scheme for our purpose. With the knowledge of transaction workload, efficacious lock trees for runtime control can be determined at compile-time. We have designed compile-time algorithms to generate the lock tree and other relevant data structures, and runtime locking/unlocking algorithms based on such structures. We have further explored how to insert the lock steps into the transaction types at compile time. <br /><br /> To conduct our simulation experiments to evaluate the performance of TL, we have designed two workloads. The first one is from the OLTP benchmark TPC-C. The second is from the open-source operating system MINIX. Our experimental results show TL produces better throughput than the traditional two-phase locking (2PL) when the transactions are write-only; and for main-memory data, TL performs comparably to 2PL even in workloads with many reads.

During the period 1980 to 2008 there were 359 fatal accidents involving UK registered light aeroplanes of which 36% occurred in visual meteorological conditions. In all, 216 lives were lost with accidents being attributed to the pilot 'failing to maintain proper control resulting in a stall or spin'. Dissimilar fatal stallrelated accident rates are evident for aeroplane makes & models of similar design. During the course of this programme of research, flight testing of two similar aeroplane models using a case study method showed marked differences in the variation of stick force with airspeed or stick force gradient in all flight conditions. This suggested that 'control feel' was a contributory factor towards the pilot’s failure to maintain proper control. Current certification standards for light aeroplanes rely upon the subjective assessment of stick force gradients by test pilots, requiring that substantial changes in airspeed are accompanied by clearly perceptible changes in stick force with no specified minimum gradient. This programme of research has been carried out to determine acceptable criteria for stick force gradients of a light aeroplane in all flight conditions. Criteria has been determined from flight tests of aeroplanes with different in-service safety records and subjective pilot workload assessment using simulated flying tasks with different stick force gradients performed by twenty GA pilots. Simulation tests indicated that pilot mental demand increased significantly (p > 0.05) when stick force gradient was reduced to ‘zero’, representing an aeroplane with neutral longitudinal static stability. A predictive model has been developed to estimate stick force gradients for a light aeroplane in any flight condition under quasi-static, longitudinal, non-manoeuvring flight and 1-g loading conditions. The model builds upon previous published work limited to cruising flight, and enables the estimation of stick forces and gradients due to high lift devices in the climb and landing condition by consideration of the combined effects of wing loading, CG, elevator gearing, flaps and elevator trim setting. Implemented using MATLAB, the model has been validated by comparing with flight test results for the case study aeroplanes and showed mean differences of ±0.025 daN/kt. The predictive model should be used in preliminary aeroplane design to assess tendencies towards neutral stability in high workload, safety critical flight conditions such as the take-off and landing. In addition, the model should be used to analyse existing aeroplanes with comparatively low or neutral stick force gradients in safety critical flight phases and to predict the effects of changing CG and/or flap limits to increase stick force gradient and improve control feel. The combined results of these studies suggest that a minimum acceptable stick force gradient for a non-aerobatic light aeroplane in all flight conditions should be nonzero and between 0.10~0.13 daN/kt. A stable and predictable stick force variation with airspeed will ensure that any substantial deviation from trimmed airspeed is accompanied by a stick force change clearly perceptible to the pilot and also provide additional warning of the proximity to the stall. The use of specific criteria to complement qualitative test pilot opinion, will assist in confirming compliance and provide consistency with current standards for sailplanes/powered sailplanes and large commercial aeroplanes, both of which already have defined minimum acceptable gradients.

Background: Hospitals face an increasing pressure towards efficiency and cost reduction while ensuring patient safety. This warrants a closer examination of the trade-off between production and protection posited in the literature for a high-risk hospital setting (intensive care). Purposes: Based on extant literature and concepts on both safety management and organizational/safety culture, this study investigates to which extent production pressure (i.e., increased staff workload and capacity utilization) and safety culture (consisting of safety climate among staff and safety tools implemented by management) influence the occurrence of medical errors and if/how safety climate and safety tools interact. Methodology / Approach: A prospective, observational, 48-hour cross-sectional study was conducted in 57 intensive care units. The dependent variable is the incidence of errors affecting those 378 patients treated throughout the entire observation period. Capacity utilization and workload were measured by indicators such as unit occupancy, nurse-/physician-to-patient ratios, levels of care, or NEMS scores. The safety tools considered include Critical Incidence Reporting Systems, audits, training, mission statements, SOPs/checklists and the use of barcodes. Safety climate was assessed using a psychometrically validated four-dimensional questionnaire. Linear regression was employed to identify the effects of the predictor variables on error rate, as well as interaction effects between safety tools and safety climate. Findings: Higher workload has a detrimental effect on safety while safety climate - unlike the examined safety tools - has a virtually equal opposite effect. Correlations between safety tools and safety climate as well as their interaction effects on error rate are mostly nonsignificant. Practice Implications: Increased workload and capacity utilization increase the occurrence of medical error; an effect that can be offset by a positive safety climate but not by formally implemented safety procedures and policies.

Current tactical networks are oversaturated, often slowing systems down to unusable speeds. Utilizing data collected from major exercises and Operation Iraqi Freedom II (OIF II), a typical model of existing tactical network performance is modeled and analyzed using NETWARS, a DISA sponsored communication systems modeling and simulation program. Optimization technologies are then introduced, such as network compression, caching, Quality of Service (QoS), and the Space Communication Protocol Standards Transport Protocol (SCPS-TP). The model is then altered to reflect an optimized system, and simulations are run for comparison. Data for the optimized model was obtained by testing commercial optimization products known as Protocol Enhancement Proxies ( Support Activity (MCTSSA) testing laboratory.
