description: Die vorliegende Arbeit befasst sich mit dem Marburger Konzentrationstraining (MKT). Im Mittelpunkt steht die Frage nach der Effektivität des Trainings bei der Durchführung in der zweiten Regelklasse. Das Trainingsprogramm wurde in zwei Klassen durchgeführt, welche die Versuchsgruppe bildeten. Zwei weitere Klassen dienten als Kontrollgruppe. Durch quantitative Forschung mittels einer selbst erstellten Lehrerbefragung und eines standardisierten Konzentrationstests wurden die Kinder beider Gruppen vor und nach dem MKT bezüglich ihrer Konzentration erfasst. Zudem wurden die Kinder der Versuchsgruppe nach ihrer Meinung über das Programm und dessen Effekte befragt.
 Die Resultate durch die Lehrerbefragung und den Konzentrationstest erweisen sich als nicht signifikant, weshalb die Effektivität des Trainings nicht nachgewiesen werden kann. Die Rückmeldungen der Kinder sind jedoch sehr positiv.

description: Ein Ausgangspunkt der robusten Statistik ist, dass der Least-Squares-Schätzer zwar einfach zu berechnen ist, aber Probleme mit Ausreißern hat. Es genügt, dass ein Punkt des Datensatzes von den anderen weit entfernt ist, um das Ergebnis stark zu verfälschen. Die robuste Statistik hat das Ziel, Schätzer zu finden, die wenig sensitiv gegenüber Ausreißern sind. Allerdings haben diese robusten Schätzer häufig den Nachteil, dass ad hoc kein schneller Algorithmus für ihre Berechnung zur Verfügung steht. In dieser Arbeit werden neue Algorithmen für einige robuste Schätzer vorgestellt: Für Punktmengen in der Ebene der Least-Quartile-Difference-Schätzer mit einer Rechenzeit von grob O(n^2 log n) und das Multiresolutions- Kriterium mit einer Rechenzeit von O(n log n). Im Kontext von Zeitreihen-Daten werden Update-Algorithmen für den Repeated-Median-Schätzer mit Update-Zeit O(n) und den Median-Absolute- Deviation-Schätzer mit Update-Zeit O(log n) vorgestellt. Für d-dimensionale Punktmengen werden Exponentialzeit-Algorithmen für den Least-Median-of-Squares-Schätzer und den Minimum-Covariance- Determinant-Schätzer vorgestellt. Abschließend wird die NP-Härte vieler robuster Schätzer bewiesen sowie eine praxisrelevante und schwierige Eingabe angegeben, so dass die Suchheuristik Fast-LTS nur mit einer exponentiell kleinen Wahrscheinlichkeit das Optimum findet. Damit wird aufgezeigt, dass die theoretischen Eigenschaften robuster Schätzer in die Praxis nur schwer zu verwirklichen sind.

description: We study possible New Physics (NP) effects in the exclusive decays $\bar{B}^0 \to D^{(\ast)} τ^- \barν_τ$. We extend the Standard Model (SM) by taking into account right-handed vector (axial), left- and right-handed (pseudo)scalar, and tensor current contributions. The $\bar{B}^0 \to D^{(\ast)}$ transition form factors are calculated in the full kinematic $q^2$ range by employing a covariant quark model developed by us. We provide constraints on NP operators based on measurements of the ratios of branching fractions $R(D^{(\ast)}) \equiv \mathcal{B}(\bar{B}^0 \to D^{(\ast)} τ^- \barν_τ)/ \mathcal{B}(\bar{B}^0 \to D^{(\ast)} μ^- \barν_μ)$ and consider the effects of these operators on physical observables in different NP scenarios. We also derive the four-fold angular distribution for the cascade decay $\bar {B}^0\to D^{\ast\,+}(\to D^0π^+)τ^-\barν_τ$ which allows one to analyze the polarization of the $D^{\ast}$ meson in the presence of NP effects. We discuss several strategies to distinguish between various NP contributions.

subject: 310

description: The rectangularization of life tables is defined as a trend towards a more rectangular shape of the survival curve due to increased survival and concentration of deaths around the mean age at death. Since the mortality of modern developed population is largely the mortality of old age, the Gompertz model provides a good approximation of life tables in these populations and can be used to estimate and forecast many parameters of the life table and the stationary population, such as expectation of life, modal age, age dependency ratios, and indices of the rectangularization of life tables. Formulas of known rectangularization indices are developed assuming the Gompertz distribution, whereas some new indices are proposed, too. The mathematical relationships between the single indices are shown. It is demonstrated that some mentioned indices are a function of the coefficient of variation.

description: Die Dissertation beschäftigt sich mit der theoretischen Analyse von Heuristiken. Im ersten und zweiten Teil werden randomisierte Heuristiken zur Optimierung im Black-Box-Szenario untersucht. Der dritte Teil befasst sich mit dem Seitenwechselproblem (Pagingproblem), das in der Regel im Online-Szenario zu lösen ist. Das Black-Box- und das Online-Szenario haben gemeinsam, dass die zu bearbeitende Probleminstanz erst im Laufe der Zeit bekannt wird, sodass Algorithmen nur heuristisch vorgehen können. Im ersten Teil wird die Laufzeit zweier einfacher evolutionärer Algorithmen, des (1+1)-EAs und der randomisierten lokalen Suche, am Beispiel des Matchingproblems im Black-Box-Szenario untersucht. Es wird gezeigt, dass beide Heuristiken effizient Maximummatchings approximieren können und dass sie zumindest für einfache Graphklassen in polynomieller erwarteter Zeit Maximummatchings finden. Andererseits gibt es Graphen, für die die Laufzeit beider Heuristiken mit einer überwältigenden Wahrscheinlichkeit exponentiell ist. Der zweite Teil untersucht einen grundlegenden evolutionären Algorithmus für mehrkriterielle Optimierungsprobleme im Black-Box-Szenario. Insbesondere wird die erwartete Laufzeit im Worst Case ermittelt und die Laufzeit für verschiedene zweikriterielle Probleme analysiert. Der dritte Teil befasst sich mit der Analyse von Heuristiken für das Seitenwechselproblem. Es werden zwei Modelle eingeführt, die unmittelbar die Analyse der Fehlerrate unter dem Aspekt der Anfragelokalität ermöglichen. In diesen Modellen werden Schranken für die Fehlerraten verschiedener deterministischer Seitenwechselstrategien bewiesen.

description: The paper deals with hybrid systems, where human actors and non-human agents meet and interact. Different from most of the literature on autonomous technology, which mainly deals with the question of agency of non-humans, the paper puts forward the assumption that the release of smart technology may lead to a deconstruction of order or even a regime change, thus raising the question of how order emerges in hybrid systems. Discussing different sociological concepts, the paper identifies two modes of governance: central control and decentralized selforganization. However, smart technology allows implementing different system's architectures, some of which may go beyond this traditional distinction. Referring to a case study on collision avoidance in aviation (and especially the mid-air collision at Ueberlingen in 2002), the paper shows that hybrid systems create new opportunities, but entail new risks as well. The release of smart technology seems to intensify well-known problems of automation, especially when systems get out of control. Aviation is one of the societal fields, where experiments with new modes of governance currently take place that combine features of central control and decentralized self-organization.

description: Task allocation research is often efficiency-focussed, but procedural and work-psychological perspectives are required to enable human-centred human–robot interaction (HRI). Hence, the motivational and cognitive outcomes of the degree of worker influence over task allocation are relevant to research objects for allocation process design. In a laboratory experiment, 87 participants manufactured goods in collaboration with a robot under three conditions: (1) a support system decided the allocation, (2) a support-system allocation could be revised, (3) the participant determined the allocation. Conditions affected mental effort, process control and autonomy, resulting in higher values when participants allocated tasks themselves. Satisfaction with the process appears lower with no worker influence. Trust in the support-system moderates the condition effect, with higher satisfaction depending on trust when a system is involved in allocation. An allocation made by the workers and adaptability is preferred. Results show the importance of worker influence over task allocation in HRI. Practitioner Summary: Our experiment on allocation processes seeks to satisfy the gap in human-centred psychological research on task allocation in human–robot interaction (HRI). For successful, ergonomic HRI, it is found that workers should be provided with influence over task allocation.

description: We study $N=(2,4,8)$ supersymmetric extensions of the three dimensional BMS algebra (BMS$_3$) with most generic possible central extensions. We find that $N$-extended supersymmetric BMS$_3$ algebras can be derived by a suitable contraction of two copies of the extended superconformal algebras. Extended algebras from all the consistent contractions are obtained by scaling left-moving and right-moving supersymmetry generators symmetrically, while Virasoro and R-symmetry generators are scaled asymmetrically. On the way, we find that the BMS/GCA correspondence does not in general hold for supersymmetric systems. Using the $β$-$γ$ and the ${\mathfrak b}$-${\mathfrak c}$ systems, we construct free field realisations of all the extended super-BMS$_3$ algebras.

description: The present study examines the life and works of St Cyril of Jerusalem. In particular, it provides a survey of the historical and religious context in which the Saint lived and discusses his life, theological training and episcopal ministry, especially with respect to his fight for preserving the Orthodox faith and combating the heresies of his day. This study also examines the writings of St Cyril, especially the so-called Baptismal and Mystagogical Catecheses, which constitute a rich repository and an invaluable source of liturgical information. Especially with respect to the Mystagogical Catecheses, the question of their authenticity is examined critically. The various positions in defense or in opposition to the traditional attribution are discussed based on current research and historical data. Finally, the issue of Christian initiation is reviewed, with and in-depth analysis of the sacramental mysteries of Baptism, Chrismation and the Holy Eucharist, which allows for the extraction of specific conclusions regarding the early sacramental theology of the Church of Jerusalem.
Thermality and excited state Rényi entropy in two-dimensional CFT

description: We evaluate one-interval Rényi entropy and entanglement entropy for the excited states of two-dimensional conformal field theory (CFT) on a cylinder, and examine their differences from the ones for the thermal state. We assume the interval to be short so that we can use operator product expansion (OPE) of twist operators to calculate Rényi entropy in terms of sum of one-point functions of OPE blocks. We find that the entanglement entropy for highly excited state and thermal state behave the same way after appropriate identification of the conformal weight of the state with the temperature. However, there exists no such universal identification for the Rényi entropy in the short-interval expansion. Therefore, the highly excited state does not look thermal when comparing its Rényi entropy to the thermal state one. As the Rényi entropy captures the higher moments of the reduced density matrix but the entanglement entropy only the average, our results imply that the emergence of thermality depends on how refined we look into the entanglement structure of the underlying pure excited state.

Utilization of Long Acting Contraceptive among Reproductive age Women in Addis Ababa Public Health Centers.
Creators: name: nigatu, bizuayehun
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Background: Long acting contraceptives such as intrauterine devices and hormonal implants are among the most effective methods that prevent unintended pregnancies. Long acting contraceptive is more convenient to clients who want to space or limit their births. Clients have better compliance to long acting contraceptive than the short acting methods, since they do not need to remember to use them or to visit family planning clinics frequently for method re-supply or administration. Objectives: To assess the utilization of long acting contraceptive among female family planning users at public health centers in Addis Ababa. Methods: A facility based cross sectional study that employed exit interviews with family planning clients and an assessment of the availability of the necessary resources was conducted in selected five public health centers, from March 11 –April 4, 2014 in Addis Ababa. Systematic sampling technique was used to select 447 study participants .Pre tested structured Amharic version questionnaire was used to collect the data through interview and inventory was carried out by using checklist. Both bivariate and multiple logistic regressions were used to identify associated factors. Result: Of 447 female family planning users interviewed 98.9% of them were aware of long acting contraceptive methods and 23.9% were using the methods. However, 48.3% respondents have negative attitude towards long acting contraceptive. Facility assessment showed that in the health centers assessed there were no shortages of resources for provision of long acting contraceptive including equipments and supply, trained health provider and contraceptives methods. Attitude of clients, previous use of long acting contraceptive, desire to have no children in the future and discussion with partners about long acting contraceptives were factors associated with long acting contraceptives use. Conclusion and recommendation: Knowledge about long acting contraceptive is high in contrary to the negative attitude for most respondents have towards the methods and low level of utilization. Providing appropriate counseling on long acting contraceptive, strengthening continuous education by model long acting contraceptive user, strengthening couple discussion and availing printed materials on long acting contraceptive are recommended.

HIV Seropositivity and Related Factors Among Prisoners in Dire Dawa
Creators: name: Kebede, Yohannes
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1989

description: HIV antibody was detected in 27 of 450 prisoners (6.0%), in a crosssectional study carried out in the major prison of Dire Daloia district, in eastern Ethiopia. Syphilis was found to be very common in the prisoners. Overall, 31.6% of the prisoners had a positive VDRL. The rate in prisoners who were HIV positive was 63% or 17 out of 27. A concurrent diagnosis of syphilis was strongly associated with HIV seropositivity. (Odd's ratio = 4.09). Recent admission to prison within the past three months was strongly associated with HIV positivity (Odd's ratio = 3.72); 21 of the 27 HIV positive prisoners had been in prison for less than three months. Factors found important in other studies on prisoners and AIDS, such as homos(3xuali ty and intravenous drug use were not found to be features of prisoners in Dire Dawa. Surprisingly, significant associations could not be proved between number of prostitute contacts or number of sexual contacts per month before prison and HIV positivity. Duration of residence in Dire Dawa town, travel outside of Dire Dawa and number of l ong term sex partners before prison, were not found to be associated with HIV seropositivity. Likewise, no statistically significant correlation was found between HIV seropositivity and history of injections, dental extractions or immunizations in the past. Only 8 of the 450 prisoners (1. 6%) were uncircumcised. Although one of the eight was HIV positive, no relationship was found between the circumcision state and HIV infection . That all 27 HIV positive prisoners had been in prison shorter than 12 months with 21 of them (77.8%) imprisoned for less than three months, suggests that the epidemic in Dire Dawa may be of recent origin. The high prevalence seen in prisoners in Dire Dawa likely reflects infection in the surrounding community, and are a cause for serious concern

description: By using the Coulomb gas technics we calculate the four-spin correlation function in the percolation $q\rightarrow 1$ limit of the Potts model. It is known that the four-point functions define the actual fusion rules of a particular model. In this respect, we find that fusion of two spins, of dimension $Δ_σ=\frac{5}{96}$, produce a new channel, in the 4-point function, which is due to the operator with dimension $Δ=5/8$.

Initial mass function of planetesimals formed by the streaming instability

description: The streaming instability is a mechanism to concentrate solid particles into overdense filaments that undergo gravitational collapse and form planetesimals. However, it remains unclear how the initial mass function of these planetesimals depends on the box dimensions of numerical simulations. To resolve this, we perform simulations of planetesimal formation with the largest box dimensions to date, allowing planetesimals to form simultaneously in multiple filaments that can only emerge within such large simulation boxes. In our simulations, planetesimals with sizes between 80 km and several hundred kilometers form. We find that a power law with a rather shallow exponential cutoff at the high-mass end represents the cumulative birth mass function better than an integrated power law. The steepness of the exponential cutoff is largely independent of box dimensions and resolution, while the exponent of the power law is not constrained at the resolutions we employ. Moreover, we find that the characteristic mass scale of the exponential cutoff correlates with the mass budget in each filament. Together with previous studies of high-resolution simulations with small box domains, our results therefore imply that the cumulative birth mass function of planetesimals is consistent with an exponentially tapered power law with a power-law exponent of approximately -1.6 and a steepness of the exponential cutoff in the range of 0.3-0.4.

description: This is the text of a citizen science project proposal, as submitted in June 2023 to the dedicated call of the french "Agence Nationale de la Recherche (ANR)": https://anr.fr/fr/detail/call/appel-a-projets-science-avec-et-pour-la-societe-recherches-participatives-2/ ------------------- Today, producing fruit without plant protection is a global challenge, a consequence of the development of intensive monoculture and the massive use of synthetic pesticides, which is reinforced by the effects of climate change. Therefore, the need for experimentation on innovative agroforestry orchard models is high. At the other end of the fruit chain, consumers, mostly city dwellers, are looking for short circuits, intelligent leisure activities and nature, and some are ready to take part in field activities. PAUZAFRUITS stands at the intersection of these needs, proposing a new model of urban agroecological experiment that promotes the development of urban commons. We focus on collective gardens as a form of urban agriculture to which we propose to add a new function, that of knowledge creation, right from their conception, through the paradigm of participatory action research. Briefly, agroforestry orchards are designed with the help of researchers, carried out from start to end by local residents, and scientifically monitored by both researchers and residents. To achieve this, we have assembled an interdisciplinary team led by an Information and Communication Sciences laboratory expert in science-society interactions (IMSIC), an association based in Marseille that manages a collective orchard (VVOUM), three laboratories with expertise in agronomy and ecology (GRAB, IMBE, INRAE-Ecodév), and the association at the head of the network of urban agricultures around Marseille (La Cité de l'Agriculture). The aim of PAUZAFRUITS is therefore to provide a proof of concept of the relevance of this proposal by implementing it on the pilot orchard managed by VVOUM, and to build a broader initiative in the form of a Living Lab dedicated to urban agroecology, which would be unique in France.

description: Background: The most common malignancy of the liver is metastases from other organs. 25–50% patients with a known non-haematological malignancy have liver metastases at the time of diagnosis. The incidence of hepatic metastases depends on the type of primary tumor and its stage at initial Detection. Ultrasonography being used worldwide with high frequency as a reliable method for the initial diagnosis of liver metastases. Aim of study: To assess the common Sonographic patterns of liver metastasis among patient with known extra hepatic primary malignancy. Materials and methods: institution based prospective cross sectional study of 93 patients with known primary extra hepatic malignancy was conducted at sonography unit of Radiology department of Tikur Anbessa specialized Hospital (TASH) Addis Ababa, Ethiopia from February 1 to August, 2017 using a sonoscape SSI-8000 model ultrasound machine. Result: The highest numbers of patients (30.1%) were in the age group of 48 – 57 followed by 38 – 47 and 58 – 67 age group respectively. 81 of 93 patients (87.1%) had multifocal liver metastases disease, where as 12 of 93 cases (12.9%) had single or solitary hepatic metastases. The commonest types of liver lesion identified were target (42%), echogenic (18 %) and Hypo echoic (17 %). Out of 21 primary breast cancer patients 13 patients had Target liver lesion and 5 had hypo echoic liver lesions. Thirteen patients with primary colonic cancer 4 had echogenic, 3 had hypo echoic and 4 had target liver lesions. Conclusion: the most common primary tumor resulting hepatic metastases are those from GI tract with colonic adenocarcinoma being on the top followed by Breast and pancreas. Majority of primary extra hepatic tumor produce multifocal liver metastases .The ultrasound pattern of liver metastases is quite varied and there is no consistent relation between the ultrasound pattern and type of tumor that allows one to specify primary malignant. The various common ultrasound patterns include multiple target, echogenic, hypo echoic and mixed patterns. Other less commonly seen Sonographic pattern of liver metastases is that of complex cystic, calcified and bizarre appearance which we couldn't easily categorized easily under above common patterns.

description: Η παρούσα μελέτη επικεντρώνεται στην διερεύνηση της επίδρασης της οικογένειας στην εγκατάσταση της ουσιοεξάρτησης. Ειδικότερα, σκοπός της είναι η αναζήτηση των οικογενειακών παραγόντων κινδύνου εξετάζοντας τις συνθήκες και τις συμπεριφορές που βιώνει ένα παιδί στο περιβάλλον του, ευνοώντας τις συνθήκες για την έναρξη ουσιών. Για την διεξαγωγή της παρούσας έρευνας επιλέχθηκε η ποιοτική μέθοδος και για την ανάλυση δεδομένων ακολουθήθηκε η Ερμηνευτική Φαινομενολογική Μέθοδος (IPA) χρησιμοποιώντας την φαινομενολογική ανάλυση. Βασικό εργαλείο της έρευνας αποτέλεσαν οι βιογραφίες των ατόμων που έχουν παρακολουθήσει την κύρια φάση θεραπείας από διάφορα προγράμματα του ΚΕΘΕΑ. Το οικογενειακό πλαίσιο φαίνεται να έχει σημαντικό ρόλο στην ανάπτυξη του παιδιού. Η έλλειψη επικοινωνίας, η συναισθηματική απουσία των γονιών, οι εντάσεις οδηγούν προς την κατεύθυνση της έναρξης της χρήσης ουσιών. Ωστόσο, εκτός από την οικογένεια δίνεται έμφαση και στον ρόλο των ομότιμων. Η εξάρτηση από ουσίες, λοιπόν, χαρακτηρίζεται ως ένα πολυπαραγοντικό φαινόμενο το οποίο αναπτύσσεται σταδιακά κάτω από πολλές και διάφορες συνθήκες.
description: The present study focuses on investigating the influence of the family on the establishment of substance dependence. In particular, it aims to search for family risk factors by examining the conditions and behaviours experienced by a child in their environment, thus favouring the conditions for substance initiation. To conduct this research, the qualitative method was chosen and the Interpretative Phenomenological Method (IPA) was followed for data analysis using phenomenological analysis. The main research tool was the biographies of the individuals who have attended the main phase of treatment from different programs of the KETHEA. The family context seems to have an important role in the child's development. The lack of communication, the emotional absence of parents and the tensions lead towards the initiation of substance use. However, besides the family, the role of peers is also emphasised. Substance dependence is therefore characterised as a multifactorial phenomenon that is developed gradually under many different circumstances.

description: One of the principal goals of controlling classical chaotic dynamical systems is known as targeting, which is the very weakly perturbative process of using the system’s extreme sensitivity to initial conditions in order to arrive at a predetermined target state. It is shown that a generalization to chaotic quantum systems is possible in the semiclassical regime, but requires tailored perturbations whose effects must undo the dynamical spreading of the evolving quantum state. The procedure described here is applied to initially minimum uncertainty wave packets in the quantum kicked rotor, a preeminent quantum chaotic paradigm, to illustrate the method, and investigate its accuracy. The method’s error can be made to vanish as ℏ→0.

description: The constitutive relations of a dense granular flow composed of self-propelling frictional hard particles are investigated by means of DEM numerical simulations. We show that the rheology, which relates the dynamical friction $μ$ and the volume fraction $ϕ$ to the inertial number $I$, depends on a dimensionless number $\mathcal{A}$, which compares the active force to the confining pressure. Two liquid/solid transitions -- in the Maxwell rigidity sense -- are observed. As soon as the activity is turned on, the packing becomes an `active solid' with a mean number of particle contacts larger than the isostatic value. The quasi-static values of $μ$ and $ϕ$ decrease with $\mathcal{A}$. At a finite value of the activity $\mathcal{A}_t$, corresponding to the isostatic condition, a second `active rigidity transition' is observed beyond which the quasi-static values of the friction vanishes and the rheology becomes Newtonian. For $\mathcal{A}>\mathcal{A}_t$, we provide evidence for a highly intermittent dynamics of this 'active fluid'.

description: Open peer review has the potential to be applied to all types of research results, from journal articles to project proposals and datasets. However, starting from its definition, criteria and procedures to assure a transparent and efficient evaluation are still debated. This discussion is embedded in the context of Open Science fulfilling the requirements of analysing structural and technological changes in the current scientific communication system. It is in this context that the Mertonian principles, in particular the ones connected with communality and organized scepticism, become important point of reference. Considering these issues, this paper intends to explore the applicability of (open) peer review to datasets produced and shared in Social Sciences. This study is part of OpenUp (OPENing UP new methods, indicators and tools for peer review, dissemination of research results, and impact measurement), a European funded project that addresses the currently transforming science landscape and aims (1) to identify ground-breaking mechanisms, processes and tools for peer-review for all types of research results (e.g., publications, data, software), (2) to explore innovative dissemination mechanisms with an outreach aim towards businesses and industry, education, and society as a whole, and (3) to analyse a set of novel indicators (i.e. altmetric) that assess the impact of research results and correlate them to channels of dissemination Since OpenUP employs a user-centered, evidence-based approach, its methodological approach not only engages all stakeholders (researchers, publishers, funders, institutions, industry, and the general public) in ad hoc workshops, conferences and training, but it also tests the achieved results in a set of seven pilots. They are related to the three project’s pillars (innovative peer review, dissemination and impact measuring) and are applied to specific research areas and communities: arts and humanities, social sciences, energy and life sciences. Within the overall objective of the project, this paper intends to provide the methodology used in developing the pilot that allows us to reconstruct the context of data sharing and evaluation in Social Sciences. Based on this analysis, the selection criteria of a research community to be involved in the pilot are identified together with the specific issues that are going to be investigated taking into account both data providers and users perspectives. The analysis is carried out considering the Mertonian principles and in particular the issues connected to their applicability to the sharing and evaluation of research data.

description: The goal of the Kattegat cod survey is to estimate the abundance, biomass and distribution of cod and to establish a fisheries independent time series of catch and effort series. Furthermore, a recruitment index will be established. The results should be used, together with commercial catch and effort data to strengthen the scientific advice on the cod stock in Kattegat. The survey will also monitor the amount and distribution of cod within the proposed “closed area” in order to analyse the effect of the closure.

description: Ambient cold exposure can pose health risks, and this study was aimed at investigating associations with musculoskeletal disorders. A postal survey was performed on 12,627 men and women, ages 18–70 years, living in northern Sweden. Statistical associations were determined using multiple logistic regression. The study sample consisted of 6,886 women (54.5%), and 5,741 men. Reporting high occupational ambient cold exposure was statistically significantly associated with neck pain (OR 1.36; 95% CI 1.16–1.59), low back pain (OR 1.38; 95% CI 1.17–1.63), and lumbar radiculopathy (OR 1.36; 95% CI 1.07–1.73), after adjusting for age, gender, body mass index, physical work load, daily smoking, and stress. Ambient cold exposure during work was an independent predictor of neck pain, low back pain, and lumbar radiculopathy. In occupational health care settings, cold exposure should be recognized as a possible risk factor for musculoskeletal disorders. Practitioner summary: This cross-sectional, survey-based study investigated associations between self-reported occupational ambient cold exposure and musculoskeletal disorders. It showed significant associations between high cold exposure and neck pain, low back pain and lumbar radiculopathy. In occupational health care settings, cold exposure should be recognized as a possible risk factor for musculoskeletal disorders.
