Is size-dependent pricing prevalent in fisheries? The case of Norwegian demersal and pelagic fisheries

It is commonly acknowledged that body weight of fish is a key factor in determining market value of landed catch, thus influencing optimal harvest strategies. However, in management strategy evaluations and bioeconomic modelling, body size is often an overlooked economic parameter, and there are no systematic studies on the prevalence of size-dependent pricing. Here we assess the presence and magnitude of size-dependent pricing in ex-vessel prices of fish in Norwegian fisheries. The data encompass landings of four pelagic and four demersal stocks in Norway in 2000.2010. Linear mixed models and generalized additive models were used to determine the dependence of unit price on weight class as well as on total yield and time (year). The results show a significant positive relationship between weight class and price for seven out of the eight examined fish stocks. The relative effect of body weight on price was the strongest for cod, Greenland halibut, Norwegian spring-spawning herring and mackerel, lesser for North Sea herring and saithe, and negligible for horse mackerel. These findings demonstrate that size-dependent pricing is common in Norwegian fisheries, and is therefore of high relevance for resource economics and fisheries management.
Feature a Prospective , descriptive study of risk Factors related to Pressure ulcer development among Patients in Intensive Care units

Many risk factors for the development of pressure ulcers (PUs) in the general hospital population have been identified, but consensus is lacking on specific PU risk factors for critical care patients. A prospective, descriptive study was conducted to determine the incidence of and risk factors for PU development among high-risk patients (Braden risk scale score <12) admitted to an intensive care unit (ICU) of a university hospital in Turkey. Demographic variables, APACHE II scores, serum albumin, hemoglobin, and glucose levels were obtained, and patients’ skin was assessed daily until discharge. Data were analyzed using percentage distributions, Student’s t-test, chi-square, and logistic regression analysis. Seventy (70) patients (22 women, 48 men), average age 56.2 (SD 19.2) years, mean albumin level 2.86 (median: 2.86, SD 2.73), and mean APACHE II score 17.2 (SD 6.48), completed the study. During an average length of stay of 17.2 days (SD 4.2), PU incidence was 28.6%. Of the 23 ulcers that developed, 12 (52.1%) were Stage I, eight (8, 34.8%) were Stage II, and three (3, 13.1%) were Stage III; no patient developed a Stage IV ulcer. Multivariate logistic regression analysis showed that being female (OR = 0.15, [95% CI:0.030.71] P <0.05) and having a lower serum albumin level (OR=11.6, [95% CI:1.9270.4] P <0.01) were independent risk factors for PU development. Patient gender and serum albumin levels should be considered as risk factors for PU development in ICU patients. Larger prospective studies examining these risk factors in ICU patients are warranted.
Combination Chemotherapy of Schistosomiasis in Laboratory Studies and Clinical Trials

Schistosomiasis is a chronic and debilitating disease that is caused by parasitic trematode worms (schistosomes). It continues to threaten millions of people, particularly the rural poor in the developing world ([11][1], [24][2]). Of the estimated 200 million infected people, more than half have
Joint effects of smoking, noise exposure and age on hearing loss.

BACKGROUND Smoking has been shown to have adverse effects on hearing, but it's unclear whether smoking interacts with known causes of hearing loss such as noise exposure and ageing. AIMS To examine the hypothesis that smoking, noise and age jointly affect hearing acuity. METHODS This cross-sectional study was carried out in 535 male adult workers of a metal processing factory. Pure-tone audiometric tests were utilized to assess hearing loss. Noise exposure assessment was based on a job exposure matrix constructed with industrial hygienist scoring and job titles. Each participant answered questionnaires about socio-demographic, life-style, occupational and health-related data. Analysis of the possible underlying biological model was undertaken assessing departures from additivity using measures of the size of the interaction present. RESULTS Age and occupational noise exposures were, separately, positively associated with hearing loss. For all the factors combined the estimated effect on hearing loss was higher than the sum of the effects from each isolated variable, especially for smoking and noise among those 20-40 years of age, and for smoking and age among those non-exposed to occupational noise. CONCLUSIONS The synergistic effect of smoking, noise exposure and age on hearing loss, found in this study, is consistent with the biological interaction. Furthermore, it is possible that distinct ototoxic substances in the chemical composition of mainstream smoke may synergistically affect hearing when in combination with noise exposure, which needs to be examined in future studies.
The formation of science choices in secondary school

In this paper I examine the formation of post‐16 choices over 3 years among higher achieving students with respect to enrolment in post‐compulsory science courses. Transcripts from four interviews carried out over 3 years with 72 secondary school students were qualitatively analysed. Students were found to shape their choices for science in a variety of ways across time. The situation regarding science choices hinges on far more dynamic considerations than the stereotypical image of the potential advanced science student, committed to becoming a scientist from an early age. There is an interplay of self‐perception with respect to science, occupational images of working scientists, relationship with significant adults and perceptions of school science The findings are informative for science educators and for career guidance professionals who may need to take into account the complexity of young people’s choices.
Attitudinal and normative processes in health behavior

Abstract Given the importance of the distinction between attitudes and subjective norms for a variety of theories and interventions in social cognition and in the psychology of health, the present article presents a review of the relevant literature. Criticisms raised against the distinction include conceptual arguments, large correlations between attitudes and subjective norms, crossover effects, and methodological issues. Points in favor of the distinction include discriminant validity data, individual differences in the weights placed on attitudes and subjective norms, experimental manipulations of attitudes and subjective norms, and cognitive clustering of the beliefs presumed to underlie attitudes and subjective norms. Finally, implications of the distinction for recent research on interventions, social identity theory, and the self are considered.
Epidural anesthesia-analgesia shortens length of stay after laparoscopic segmental colectomy for benign pathology.

BACKGROUND Aggressive postoperative care plans after open colectomy may allow earlier discharge, especially in conjunction with preoperative thoracic epidural anesthesia-analgesia using a local anesthetic and narcotic. The purpose of this study was to evaluate the role of thoracic epidural anesthesia-analgesia using bupivacaine and fentanyl citrate in reducing lengths of stay after laparoscopic colectomy (LAC). METHODS A consecutive cohort of patients who underwent LAC and who received perioperative thoracic epidural anesthesia-analgesia (TEG) was compared with a standard group of patients (STD) undergoing LAC during the 2 months preceding the implementation of the epidural management protocol. Patients with TEG received 6 to 8 mL bupivacaine (0.25%) and fentanyl citrate (100 microg) through a T8-9 or a T9-10 epidural catheter before the incision was made and a postoperative infusion of bupivacaine (0.1%) and fentanyl citrate (5 microg/mL) at 4 to 6 mL/h for 18 hours. STD patients had supplemental intravenous morphine. The postoperative care plan was otherwise identical between the 2 groups. Patients were matched by sex, age, and type of segmental resection. Discharge criteria included tolerance of 3 general diet meals, passage of flatus or stool, and adequate oral analgesia. Length of stay was defined as the time from admission for the surgical procedure to discharge from the hospital. Statistical analysis included a Student t test, Wilcoxon rank sum test, chi-square trend test, and Fisher exact test where appropriate. Data are presented as mean +/- SEM. RESULTS Procedures performed were: right hemicolectomy-ileocolectomy (TEG, n = 5; STD, n = 5); or sigmoid colectomy-rectopexy (TEG, n = 17; STD, n = 17). There was no significant difference with respect to operating room (OR) time (TEG, 102 +/- 12 minutes; STD, 87 +/- 17 minutes), body mass index (TEG, 26 +/- 2; STD, 26 +/- 2), or American Society of Anesthesiologists class (I-III) distribution (TEG, 3/12/10; STD, 4/11/7), or mean incision length (TEG, 3.5 +/- 0.4 cm; STD, 3.7 +/- 0.3 cm.) No postoperative complications or readmissions occurred in either group. The length of stay decreased in the TEG group (TEG, 2.8 +/- 0.2 days; STD, 3.9 +/- 0.3; P <.001) and the median length of stay for the 2 groups was similarly less (TEG, 2 days; STD, 3 days). CONCLUSIONS These data suggest that thoracic epidural anesthesia-analgesia has a significant and favorable impact on dietary tolerance and length of stay after LAC. A thoracic epidural appears to be an important component of a postoperative care protocol, which adds further advantage to LAC without the need for labor-intensive and costly patient care plans.
Overtime and Need for Recovery in Relation to Job Demands and Job Control

Overtime and Need for Recovery in Relation to Job Demands and Job Control: Monique van der Hulst, et al. Department of Work and Organizational Psychology, Radboud University Nijmegen, The Netherlands—This study addressed the prevalence of working overtime in relation to psychosocial work characteristics and need for recovery. More precisely, the aim of this study was to find out (1) whether a relationship exists between working overtime and psychosocial work characteristics (job demands and job control), (2a) whether a relationship exists between working overtime and need for recovery, and finally (2b) whether such a relationship depends on job type (a specific combination of job demands and job control). The study sample (N=1,473) consisted of a national random sample of office‐based municipal administration employees who worked full‐time. These employees completed a questionnaire on working conditions, overtime and need for recovery, among other things. Overtime was especially common in jobs characterised by high demands. The analyses showed that working overtime is not associated with a higher need for recovery in the total study population. However, there was a positive relationship between overtime hours and need for recovery in high strain jobs (high demands, low control). Furthermore, there was a positive relationship between structural overtime and need for recovery in active jobs (high demands, high control). The relationship between overtime and need for recovery seems to be dependent upon working conditions; indicators of overtime were associated with a higher need for recovery only for employees who experienced high job demands. Longitudinal research within a heterogeneous sample will be necessary to draw firm conclusions about causality with respect to the relationship between overtime, need for recovery and working conditions.

Effect of Chordwise Deformation on Unsteady Aerodynamic Mechanisms in Hovering Flapping Flight

A three-dimensional simulation of hovering flapping wings was performed using an immersed boundary method. This was done to investigate the effects of chordwise wing deformation on three important unsteady aerodynamic mechanisms found in flapping flight, namely Leading Edge Vortex (LEV) shedding, wake capture and clap and fling. A wing was modeled as a flat plate, flapping close to a symmetry plane. Three different deforming chords were defined, a rigid case, a case with maximum deformation at the trailing edge and increased angle of attack (AoA) near the leading edge, and a case with the maximum deformation in the center of the chord and decreased AoA near the leading edge. All cases had zero deformation at the wing root and maximal deformation at the wing tip. A higher AoA near the leading edge resulted in faster LEV buildup and faster buildup of lift. No shedding of the LEV was observed in any of the cases even when deformation caused a high AoA near the leading edge. A distinct dip in lift buildup was observed and shown to be caused by the interaction between the previously shed vortex and the newly developing LEV. This interaction occurred faster when the AoA at the leading edge was increased, and slower when the angle of attack was decreased. Moving the wing closer to the symmetry plane had a positive effect on the cycle average value of CL. This positive effect was reduced however by the earlier interaction between the LEV and the previously shed vortex.

Results: We identified 19 studies including 628 patients with GIST. Main findings of included studies are presented. Conclusions: F-FDG PET has a significant value in assessing treatment response to imatinib or other drugs in GIST patients. F-FDG PET allows an early assessment of treatment response and is a strong predictor of clinical outcome. © 2012 Elsevier Inc. All rights reserved.
Pre-speech diagnosis in hearing-impaired infants: How auditory experience affects early vocal development

Abstract Using frequent recordings of spontaneous vocalizations from cooing to word production and applying signal analysis methods, we aimed to objectively determine the developmental pre-speech profiles of young hearing-impaired infants with regard to the duration of auditory deprivation and the benefit accrued from hearing aids. The assessment of the benefit from amplification of the hearing level in infants is limited to subjective observation. In this pilot study, we aimed to demonstrate the advantage of an objective fine-grained analysis in three representative infants with similar audiological findings but different early auditory experience. The infants were born with profound hearing loss and aided at different ages within 6 months after birth. Spectral analysis and formant analysis of more than 11 000 vocalizations were performed. This allowed for a reliable identification of the time points at which each infant reached the early vocal stages. The analysis demonstrated that individual developmental courses from cooing to word production varied depending on the duration of early auditory deprivation. The findings suggest that inadequate auditory input affects infants’ vocal development long before the stage of first speech-like vocalizations (canonical babbling). Pre-speech diagnosis as introduced here may offer an additional objective tool in the diagnosis of hearing impairment in pre-lexical infants and in the assessment of the benefit of amplification.
Impact of the health and living conditions of migrant and non-migrant Senegalese adolescent girls on their nutritional status and growth

Abstract Objective: To describe the living conditions of Senegalese adolescent girls according to their migration status, and to define the main socio-economic and biological determinants of their nutritional and growth status. Design: Health and living conditions, sexual maturation, and nutritional and growth status of adolescent girls were determined within the framework of a longitudinal study on growth. Settings: The capital city of Senegal (Dakar) and a rural community (Niakhar), 120 km south-east of Dakar. Subjects: Three hundred and thirty-one girls, 14.5–16.6 years of age, were recruited from the same villages. Thirty-six per cent of the sample remained in the villages to attend school and/or to help with household subsistence tasks (non-migrants). The remaining (64%) migrated to cities to work as maids (migrants) and lived in two different socio-economic environments: at the home of a guardian during the night and in the house of the employer during the daytime. Results: Family rural environment and guardian and employer urban environments were socio-economically different (P < 0.001). Living conditions in urban areas were better than in rural areas and the employer's environment was socio-economically more favourable. Migrants had more advanced sexual maturation and higher body mass index (BMI), fat mass index (FMI) and mid-upper arm circumference than non-migrants. However, migrants were smaller than non-migrants. BMI, FMI and weight-for-age were related to socio-economic levels and duration of migration. Schooling was positively related to height and negatively related to BMI. Conclusions: Migrants enjoyed better living conditions than non-migrants. This could be partly due to the better socio-economic environment of the employer. It was associated with earlier puberty and better nutritional status, but not with a better growth.
Depression, anxiety, and apathy in Parkinson's disease: insights from neuroimaging studies

Depression, anxiety and apathy are common mood disturbances in Parkinson's disease (PD) but their pathophysiology is unclear. Advanced neuroimaging has been increasingly used to unravel neural substrates linked to these disturbances. A systematic review is provided of neuroimaging findings in depression, anxiety and apathy in PD. A PubMed, MEDLINE and EMBASE search of peer‐reviewed original research articles on these mood disturbances in PD identified 38 studies on depression, eight on anxiety and 14 on apathy in PD. Most of the imaging studies used either position emission tomography or single‐photon emission computed tomography techniques. These studies generally suggest increased neural activity in the prefrontal regions and decreased functional connectivity between the prefrontal−limbic networks in depressed patients. Functional imaging studies revealed an inverse correlation between dopaminergic density in the caudate and putamen with the severity of anxiety in PD. There was no consistent correlation between dopaminergic density of thalamus and anxiety. Studies demonstrated both positive and inverse correlations between apathy and metabolism or activity in the striatum, amygdalar, prefrontal, temporal and parietal regions. The clinical variability of study subjects and differences in image pre‐processing and analytical strategies may contribute to discrepant findings in these studies. Both nigrostriatal and extra‐nigrostriatal pathways (in particular the frontal region and its connecting areas) are affected in mood disorders in PD. Identifying the relative contributions of these neural pathways in PD patients with overlapping motor and mood symptoms could provide new pathophysiological clues for the development of better therapeutic targets for affected patients.
Exploring the Role of Control - Smart Meter Acceptance of Residential Consumers

The increasing diffusion of renewable energies which underlie significant daily and seasonal fluctuations increases grid operations’ complexity. For the effective use of renewable energies, innovative information and communication technologies (ICT) and concepts are necessary to efficiently balance power generation and consumption. An ICT-based innovation in this context is the smart metering technology allowing bidirectional transfer of information between energy systems’ components. Using a context-specific extension of the Technology Acceptance Model (TAM) of Davis (1989), our study investigates smart meters’ acceptance based on the attitude toward use and the salient beliefs perceived usefulness, perceived ease of use, and subjective control. Results support the theorized relationships indicating that the attitude toward use fully mediates the relationship between perceived usefulness, perceived ease of use, and subjective control on intention to use. In the conclusion a detailed discussion of the study’s findings is provided and the implications for research, practice, and policy are highlighted.
Paediatric thoracic empyema in an Ethiopian referral hospital.

OBJECTIVES To analyse underlying conditions, clinical manifestations, aetiologic agents and management of empyema thoracis and to determine the outcome of the disease. DESIGN A retrospective study. SETTING Ethio-Swedish Children's Central referral (teaching) Hospital, Addis Ababa, Ethiopia. SUBJECTS Thirty eight patients with a discharge diagnosis of non-tuberculous thoracic empyema seen from January 1988 to December 1992. RESULTS The incidence was 2.7/1000 admissions, which is higher than that reported elsewhere. Sixty six per cent of the patients were under five. Pneumonia was the antecedent illness in almost all cases. Fever, dyspnoea and signs of respiratory distress and effusion were the commonest presenting features. Bacteriological examination revealed Staphylococcus aureus as the commonest aetiologic agent (58%). All patients were treated with antibiotics, and drainage of the empyema was effected by closed thoracostomy in 71% of the cases, while the rest were managed with thoracentesis alone. The case fatality rate was 16%. A long hospital stay and high rate of complications were also observed. CONCLUSION Empyema is not rare in our practice. Early diagnosis and proper treatment of pneumonia prevents the development of empyema. Therefore, establishing an efficient management protocol that is relevant to our particular set up is required.
