Organisering av ekonomiskt bistånd – Perspektiv på en integrerad och en specialiserad kommun
No full textAuthor: Merima Colak Title: Organization of financial assistance - Perspective on an integrated and a specialized municipality [translated title] Supervisor: Håkan Johansson Assessor: Staffan Blomberg The purpose of this study was to examine how specialized and integrated social services manage their social assistance. In addition to this the aim was to examine how social workers and officials working within these two forms of organizations experience discretion. Furthermore, a goal of this paper was also to examine if the social workers felt that any of these two organizational forms had any impact on the workload and how that in such case manifested. The study was conducted through a qualitative research method. Six social workers and officials were interviewed for the study. The results from the study demonstrated that the employees in the integrated organization had more general work tasks and that those in the specialized organization had their tasks divided on different units that were more specialized. Findings also showed that employees in each municipality interpret discretion differently. The social workers from the integrated organization interpreted discretion in terms of being able to affect their client’s case. The social workers from the specialized organization, on the other hand, defined discretion as being able to influence their own daily work tasks. Conclusively, the study showed that workload exists in both municipalities and that it was manageable in each of the municipalities, the workload was however higher in the specialized one but it was no burden on the employees in neither the specialized nor the integrated. Key words: Discretion, organizational structure, integrated and specialized organizations, social assistance, workload.

The reliability of the augmented Lehnert-Schroth and Rigo classification in scoliosis management
No full textBackground: In pattern-specific scoliosis exercises and bracing, the corrective treatment plan differs according to different curve patterns. There are a limited number of studies investigating the reliability of the commonly used classifications systems. Objective: To test the reliability of the augmented Lehnert-Schroth (ALS) classification and the Rigo classification. Methods: X-rays and posterior photographs of 45 patients with scoliosis were sent by the first author to three clinicians twice at 1-week intervals. The clinicians classified images according to the ALS and Rigo classifications, and the data were analysed using SPSS V-16. Intraclass correlation coefficients (ICCs) and standard error measurement (SEM) were calculated to evaluate the inter-and intra-observer reliability. Results: The inter-observer ICC values were 0.552 (ALS), 0.452 (Rigo) for X-ray images and 0.494 (ALS), 0.518 (Rigo) for the photographs. The average intra-observer ICC value was 0.720 (ALS), 0.581 (Rigo) for the X-ray images and 0.726 (ALS) and 0.467 (Rigo) for the photographs. Conclusions: The results of our study indicate moderate inter-observer reliability for X-ray images using the ALS classification and clinical photographs using the Rigo classification. Intra-observer reliability was moderate to good for X-ray images and clinical photographs using the ALS classification and poor to moderate for X-ray and clinical photographs using the Rigo classification
Investigation of the characteristics of low-cost and lightweight horn array antennas with novel monolithic waveguide feeding networks

Proposed novel fabrication method consists of two main steps that are to make the skeleton of horn array antenna from acrylonitrile butadiene styrene (ABS) thermoplastic via 3D printer and to perform copper plating over all surface of antenna by using the electroless plating and electroplating processes. The WFN structures with 3 lambda element spacing designed and realized by using WR75 waveguide T-junction, E-type bend, and UDR 120 flange. Qualitative agreement between measurement and simulation via CST Microwave Studio is obtained with max 1 dB due to high precision and surface roughness. The gains of array antennas are increased by about 1.5 dB and 3 dB, respectively compared to the single antenna. VSWRs of array antennas are 0.3 dB and 0.6 dB, respectively higher than the single one. In the study, proposed 3D printed components not only with 90% lighter weight than, but also with 80% cheaper than commercial products, and horn arrays with -40 dB cross-polarization values.Department of Scientific Research Projects in Suleyman Demirel University [4605-D2-16]; State Planning Organization in Turkey [2007K120530-DPT]We also would like to thank to Akdeniz University Scientific Research Projects Supporting Unit (BAP), and Akdeniz University EMUMAM Directorate allowing us to use their facilities granted by State Planning Organization in Turkey (2007K120530-DPT).

Objectives: The present study explored public’s willingness to use COVID-19 immunity certificates across six different domestic scenarios.
Design: Cross-sectional online survey.
Setting: UK representative survey conducted on 3 August 2021.
Participants 534 UK residents over 18 years old.
Interventions: Participants replied to the same set of questions.
Primary and secondary outcome measures: The primary outcome measure was willingness to use immunity certificates across three different domestic settings: (1) visiting the general practitioner (GP) for a non-urgent health issue; (2) dining in a restaurant and (3) attending a performance in a theatre. For each setting two options, one prioritising convenience (option A) and the other privacy (option B), were offered. Our secondary outcome measures were computed indices from items adapted from the Health Belief Model; attitudes towards sharing immunity status with service providers; prior to COVID-19 lifestyle. In addition, we recorded data about respondents’ sociodemographic characteristics.
Results: Respondents were more willing to use immunity certificates that prioritised convenience (92%), rather than privacy (76%), when visiting their GP . However, privacy was more favourable in the other two settings (dining in a restaurant (84%) and going to a theatre (83%)) compared with convenience (38% and 39% respectively). Personal beliefs about COVID-19 and immunity certificates were associated with variations in willingness to use these across all scenarios. No variations were observed across sociodemographics and lifestyle.
Conclusions: The findings of this survey suggest that there is not one-size-fits-all solution for designing immunity certificates. Immunity certificates are complex sociotechnical systems, any attempt to implement these for domestic use should be tailored to different settings and user needs. The design of certification services requires a more evidence-based approach and further research is needed to understand how different settings, design elements (like convenience or privacy) and personal beliefs about the pandemic should inform their design.IMMUNE or Immunity Passport Service Design is a nine-month project funded by the AHRC/UKRI COVID-19 Rapid Response (Ref.

Illicit Drug Analysis in Blood Samples with Multivariate Analysis Using Surface-Enhanced Raman Spectroscopy
No full textThis study aims to discriminate different types of illicit drugs ( MDMA and THC) in blood samples using surface- enhanced Raman spectroscopy ( SERS) combined with chemometric techniques including principal components analysis (PCA) and par tial least squares discriminant analysis (PLS- DA). A PLS- DA classification model was built using a training data set containing Raman spectra from control and experimental groups (drug-detected blood). PLS- DA was performed for discrimination and classification among blood samples. The scores obtained in the PLS- DA model were used to evaluate the performance of the created model. The leave one out cross-validation (LOOCV) method was used for calibration and validation of the PLS-DA model. In the study, it was observed that the SERS method and chemometric techniques together could be used in drug analysis, even at low concentrations in complex body fluids such as blood. As a result, Raman spectroscopy with PCA and PLS- DA methods of data analysis could be used extensively to build similar or different classification models
