Modelling and Verification of a Correction Factor to Evaluate the Efficiency of Solar Thermal Collectors with the Rapid Test Method

A new method for the evaluation of the efficiency of parabolic trough collectors, called Rapid Test Method, is investigated at the Solar Institut Jülich. The basic concept is to carry out measurements under stagnation conditions. This allows a fast and inexpensive process due to the fact that no working fluid is required. With this approach, the temperature reached by the inner wall of the receiver is assumed to be the stagnation temperature and hence the average temperature inside the collector. This leads to a systematic error which can be rectified through the introduction of a correction factor. A model of the collector is simulated with COMSOL Multipyisics to study the size of the correction factor depending on collector geometry and working conditions. The resulting values are compared with experimental data obtained at a test rig at the Solar Institut Jülich. These results do not match with the simulated ones. Consequentially, it was not pos-sible to verify the model. The reliability of both the model with COMSOL Multiphysics and of the measurements are analysed. The influence of the correction factor on the rapid test method is also studied, as well as the possibility of neglecting it by measuring the receiver’s inner wall temperature where it receives the least amount of solar rays. The last two chapters analyse the specific heat capacity as a function of pressure and tem-perature and present some considerations about the uncertainties on the efficiency curve obtained with the Rapid Test Method.

Theory development in humanitarian logistics : A framework and three cases

Purpose: There is a need for theory development within the field of humanitarian logistics to understand logistics needs in different stages of a crisis and how to meet these. This paper aims to discuss three dimensions identified in logistics and organization theories and how they relate to three different cases of humanitarian logistics operations - the regional concept of the International Federation of Red Cross Red Crescent Societies, the development and working of the United Nations Joint Logistics Centre and coordination challenges of military logistics in UN mandated peacekeeping operations. The purpose is to build a framework to be used in further studies. Design/methodology/approach: A framework for the study of humanitarian logistics along three dimensions is developed, followed by a discussion of the chosen cases in relation to these dimensions. The framework will be used as basis for the case studies to be undertaken for the purpose of understanding and identification of new questions and needs for other or revised concepts from theory. Findings: The paper shows the relevance of a wide literature to the issues pertinent to humanitarian logistics. There is considerable promise in extant literature on logistics, SCM and coordination, but this needs to be confronted with the particular issues seen in the humanitarian logistics setting to achieve further theory development. Originality/value: The major contribution of the paper lies in its breadth of theoretical perspectives presented and combined in a preliminary theoretical framework. This is applied more specifically in the three case studies described in the paper.

Whistleblowing process in Finnish health care

Wrongdoing in health care is harmful action that jeopardizes patient safety and can be targeted at the patient or employees. Wrongdoing can vary from illegal, unethical or unprofessional action to inappropriate behavior in the workplace. Whistleblowing can be considered as a process where wrongdoing is suspected or oberved in health care by health care professionals and disclosed to the party that can influence the wrongful action. Whistleblowing causes severe harm to the whistleblower and to the object of whistleblowing complaint, to their personnel life and working community. The aim of this study was to analyze whistleblowing process in Finnish health care. The overall goal is to raise concern about wrongdoing and whistleblowing in Finnish health care. In this cross-sectional descriptive study the data were collected (n = 397) with probability sampling from health care professionals and members of The Union of Health and Social Care Professionals in Finland Tehy. The data were collected with questionnaire: “Whistleblowing -väärinkäytösten paljastaminen terveydenhuollossa” developed for this study and by using Webropol questionnaire -software during 26.6.-17.7.2015. The data were analyzed statistically. According to the results of this study health care professionals had suspected (67 %) and observed (66 %) wrongdoing in health care, more often than once a month (30%). Mostly were suspected (37 %) and observed (36%) inadequacy of the personnel and least violence toward the patient (3 %). Wrongdoing was whistle blown (suspected 29 %, observed 40 %) primarily inside the organization to the closest supervisor (76 %), face-to-face (88 %). Mostly the whistle was blown on nurses’ wrongdoing (58 %). Whistleblowing act didn’t end the wrongdoing (52 %) and whistleblowing had negative consequences to the whistleblower such as discrimination by the manager (35 %). Respondents with work experience less than ten years (62 %), working in temporary position (75 %) or in management position (88 %) were, more unwilling to blow the whistle. Whistleblowing should be conducted internally, to the closest manager in writing and anonymously. Wrongdoing should be dealt between the parties involved, and written warning should ensue from wrongdoing. According to the results of this study whistleblowing on wrongdoing in health care causes negative consequences to the whistleblower. In future, attention in health care should be paid to preventing wrongdoing and enhancing whistleblowing in order to decrease wrongdoing and lessen the consequences that whistleblowers face after blowing the whistle.

Running on Rooftops: a novel and critical reflection on writing from an identity of expatriation with an examination of West-meets-East encounters and attitudes depicted in literature

This thesis is in two parts: a creative work of fiction and a critical reflection on writing from an identity of expatriation. The creative work, a novel entitled Running on Rooftops, revolves around a fictitious community of expatriates living and working in China. As a new college graduate, Anne Henry, the novel’s protagonist and narrator, decides to spend a year teaching English in China. Twelve years later, though still unsure of how to make sense of the chain of events and encounters that left her with an X-shaped scar on her knee, she nevertheless tells the story, revealing how “just a year” can be anything but. The critical reflection, entitled Writing on Rooftops, explores the nature of expatriation as it relates to identity and writing, specifically in how West-meets-East encounters and attitudes are depicted in literature. In it, I examine the challenges and benefits of writing from an identity and mindset of expatriation as illustrated in the works of Western writers who themselves experienced and wrote from viewpoints of expatriation, particularly those Western writers who wrote of expatriation in China and Southeast Asia. The primary question addressed is how expatriation influences perception and how those perceptions among Western foreigners in China and Southeast Asia have been and can be reflected in literature. In the end, I argue that expatriation can be a valuable viewpoint to write from, offering new ways of seeing and describing our world, ourselves and the connections between the two.

THE RELATIVE SIGNIFICANCE OF SYNTACTIC KNOWLEDGE AND VOCABULARY KNOWLEDGE IN SECOND LANGUAGE LISTENING COMPREHENSION

The main purpose of the current study was to examine the role of vocabulary knowledge (VK) and syntactic knowledge (SK) in L2 listening comprehension, as well as their relative significance. Unlike previous studies, the current project employed assessment tasks to measure aural and proceduralized VK and SK. In terms of VK, to avoid under-representing the construct, measures of both breadth (VB) and depth (VD) were included. Additionally, the current study examined the role of VK and SK by accounting for individual differences in two important cognitive factors in L2 listening: metacognitive knowledge (MK) and working memory (WM). Also, to explore the role of VK and SK more fully, the current study accounted for the negative impact of anxiety on WM and L2 listening. The study was carried out in an English as a Foreign Language (EFL) context, and participants were 263 Iranian learners at a wide range of English proficiency from lower-intermediate to advanced. Participants took a battery of ten linguistic, cognitive and affective measures. Then, the collected data were subjected to several preliminary analyses, but structural equation modeling (SEM) was then used as the primary analysis method to answer the study research questions. Results of the preliminary analyses revealed that MK and WM were significant predictors of L2 listening ability; thus, they were kept in the main SEM analyses. The significant role of WM was only observed when the negative effect of anxiety on WM was accounted for. Preliminary analyses also showed that VB and VD were not distinct measures of VK. However, the results also showed that if VB and VD were considered separate, VD was a better predictor of L2 listening success. The main analyses of the current study revealed a significant role for both VK and SK in explaining success in L2 listening comprehension, which differs from findings from previous empirical studies. However, SEM analysis did not reveal a statistically significant difference in terms of the predictive power of the two linguistic factors. Descriptive results of the SEM analysis, along with results from regression analysis, indicated to a more significant role for VK.

Ultra high pressure homogenization (UHPH) inactivation of Bacillus amyloliquefaciens spores in phosphate buffered saline (PBS) and milk

Ultra high pressure homogenization (UHPH) opens up new areas for dynamic high pressure assisted thermal sterilization of liquids. Bacillus amyloliquefaciens spores are resistant to high isostatic pressure and temperature and were suggested as potential surrogate for high pressure thermal sterilization validation. B. amyloliquefaciens spores suspended in PBS buffer (0.01 M, pH 7.0), low fat milk (1.5%, pH 6.7), and whole milk (3.5%, pH 6.7) at initial concentration of similar to 10(6) CFU/mL were subjected to UHPH treatments at 200, 300, and 350 MPa with an inlet temperature at similar to 80 degrees C. Thermal inactivation kinetics of B. amyloliquefaciens spores in PBS and milk were assessed with thin wall glass capillaries and modeled using first-order and Weibull models. The residence time during UHPH treatments was estimated to determine the contribution of temperature to spore inactivation by UHPH. No sublethal injury was detected after UHPH treatments using sodium chloride as selective component in the nutrient agar medium. The inactivation profiles of spores in PBS buffer and milk were compared and fat provided no clear protective effect for spores against treatments. Treatment at 200 MPa with valve temperatures lower than 125 degrees C caused no reduction of spores. A reduction of 3.5 log(10)CFU/mL of B. amyloliquefaciens spores was achieved by treatment at 350 MPa with a valve temperature higher than 150 degrees C. The modeled thermal inactivation and observed inactivation during UHPH treatments suggest that temperature could be the main lethal effect driving inactivation.

Attachment Style, Therapeutic Alliance and Recovery in forensic mental health: the A-STAR study and clinical research portfolio

Background: Research suggests that forensic mental health services and staff can play an important role in the recognition and intervention with attachment-related behaviours to promote engagement and recovery. There is a lack of literature exploring whether the attachment needs of forensic service-users are recognised and, associations between attachment style and factors predictive of recovery. Aims: This study aimed to examine the extent to which service-users and keyworkers agree about service-users’ attachment and to identify whether attachment was associated with service attachment, working alliance, ward climate and recovery. Methods: Twenty-two service-users from low and medium secure forensic services, completed questionnaire measures of their attachment style, service attachment, working alliance, ward climate and experiences of recovery. Nineteen keyworkers completed measures of the service-users attachment style and working alliance. Results: There was strong agreement between service-users and staff for attachment anxiety (ICC=0.71) but poor agreement for attachment avoidance (ICC=0.39). Service attachment was associated with more positive perceptions of staff support (r=0.49) and avoidant attachment was associated with lower ratings of recovery (r=-0.51). Correlations between attachment style and service attachment, working alliance and ward climate were small and non-significant. Conclusions: A focus on staff training to support recognition of the nature and impact of avoidant attachment styles is indicated. The findings suggest that interventions to enhance staff - service-user relationships may be important for service attachment and indeed promotion of a recovery focused orientation amongst service-users high in avoidant attachment may improve wellbeing and outcomes.

Education in occupational health psychology: Where have we been, where are we now and where are we going?

At the first full conference of the European Academy of Occupational Health Psychology (Lund, 1999), the decision was ratified to organise activities around three fora. These together represented the pillars on which the European Academy had been founded that same year: education, research and professional practice. Each forum was convened by a chair person and a small group of full members; it was agreed that a forum meeting would take place at each full conference and working groups would be established to move developments forward between conferences. The forum system has proven an effective means by which to channel the energies of individual members, and the institutions that they represent, towards advancements in all three areas of activity in occupational health psychology (OHP) in Europe. During the meeting of the education forum at the third full European Academy conference (Barcelona, 2001), the proposal was made for the establishment of a working party that would be tasked with the production of a strategy document on The Promotion of Education in Occupational Health Psychology in Europe. The proposal was ratified at the subsequent annual business meeting held during the same conference. The draft outline of the strategy document was published for consultation in the European Academy’s e-newsletter (Vol. 3.1, 2002) and the final document presented to the meeting of the education forum at the fourth full conference (Vienna, 2002). The strategy document constituted a seminal piece of literature in so far as it provided a foundation and structure capable of guiding pan-European developments in education in OHP – developments that would ensure the sustained growth of the discipline and assure it of a long-standing embedded place in both the scholarly and professional domains. To these ends, the strategy document presented six objectives as important for the sustained expansion and the promotion of education in the discipline in Europe. Namely, the development of: [1] A core syllabus for education in occupational health psychology [2] A mechanism for identifying, recognising and listing undergraduate and postgraduate modules and courses (programmes) in occupational health psychology [3] Structures to support the extension of the current provision of education in occupational health psychology [4] Ways of enhancing convergence of the current provision of education in occupational health psychology [5] Ways of encouraging regional cooperation between education providers across the regions of Europe [6] Ways of ensuring consistency with North American developments in education and promoting world wide co-operation in education Five years has elapsed since the presentation of these laudable objectives to the meeting of the education forum in Vienna in December 2002. In that time OHP has undergone considerable growth, particularly in Europe and North America. Expansion has been reflected in the evolution of existing, and emergence of new, representative bodies for the discipline on both sides of the Atlantic Ocean. As such, it might be considered timely to pause to reflect on what has been achieved in respect of each of the objectives set out in the strategy document. The current chapter examines progress on the six objectives and considers what remains to be done. This exercise is entered into not merely in order to congratulate achievements in some areas and lament slow progress in others. Rather, on the one hand it serves to highlight areas where real progress has been made with a view to the presentation of these areas as ripe for further capitalisation. On the other hand it serves to direct the attention of stakeholders (all those with a vested interest in OHP) to those key parts of the jigsaw puzzle that is the development of a self-sustaining pan-European education framework which remain to be satisfactorily addressed.

Cytogenotoxicity biomarkers in fat snook Centropomus parallelus from Cananeia and Sao Vicente estuaries, SP, Brazil

The aquatic environment receives many contaminants that can induce damages at the molecular, biochemical, cellular and physiological levels. Centropomus parallelus, an important food resource for local populations, is a predator fish that feeds on small fishes and benthic invertebrates, thus being vulnerable to the bioconcentration and biomagnification processes. This study aimed to evaluate cytogenotoxic responses in erythrocytes from C. parallelus juveniles collected in the Cananeia and Sao Vicente estuaries, both in winter and in summer. After anesthesia, blood samples were collected by caudal puncture. Blood smears were prepared on glass slides and stained with May-Grunwald-Giemsa dye. Two thousand cells were analyzed per slide (1000x), and nuclear abnormalities (NA) and micronuclei (MN) were scored. The Sao Vicente sample showed MN and NA frequencies (%/1000 cells) of 0.325 and 3.575, in winter, and of 0.125 and 2.935 in summer respectively; the Cananeia sample showed frequencies of 0.0325 and 0.03, in winter, and of 0.065 and 0.355 in summer, respectively. The rates found in Sao Vicente were significantly higher than those found in Cananeia, evidencing that the levels of pollution in that estuary were high enough to induce genetic damages.

Regional Disparities in Sedentary Behaviors and Meal Frequency in Iranian Adolescents: The CASPIAN-III Study

Background: The prevalence of obesity is increasing among Iranian youngsters like other developing countries. Objectives: This study was conducted to assess regional disparities in sedentary behaviors and meal frequency in Iranian adolescents. Patients and Methods: In this national survey, 5682 students aged 10 - 18 years from urban and rural districts of 27 provinces of Iran were selected via stratified multi-stage sampling method. The country was classified into four sub-national regions, based on criteria of the combination of geography and socioeconomic status (SES). Mean of meal frequency and physical activity levels as well as prevalence of omitting meals and sedentary behavior were compared across regions with different SES after stratifying with sex and age group. Results: Meal frequency in lower socio-economic regions was significantly higher than two other regions in 10 - 13 and 10 - 18 years old groups (P trend < 0.001). However, the mean of working hours with computer was linearly increased with increasing the SES in studied regions (P trend < 0.001), whereas the corresponding figure was not significant for the mean of watching TV (P trend > 0.05). Frequency of adolescents omitting their meals was higher in higher SES regions especially in West Iran (P < 0.001) in 10 - 13 years old age group. Having personal computer and working with it more than two hours per day mainly was observed in central Iran which ranked as the highest SES group. Conclusions: Efforts to ensure Iranian youth meet healthy food habits and screen time guidelines include limiting access to screen technologies and encouraging parents to monitor their own screen time is required.
