All-time low period fertility in Finland: drivers, tempo effects, and cohort implications

In several European countries previously characterized by relatively high and stable cohort fertility, and particularly in the Nordic countries, period total fertility rates (TFR) have declined since 2010. The largest of these declines has been observed in Finland, where the TFR reached an all-time low of 1.49 in 2017. We analyze the decrease in the TFR in Finland since 2010, and assess the consequences of this trend for the completed fertility of women currently of childbearing age using complementary approaches that build on existing parametric and novel nonparametric methods. Decomposition of the fertility decline shows that this trend has been close to universal, with all age groups and parities contributing, but with first-order births and ages 25-29 making the largest contributions. At older ages, we document an important qualitative shift in fertility dynamics: for the first time since the early 1970s, women aged 30+ are experiencing a sustained fertility decline. All of our forecasting methods suggest that cohort fertility is likely to decline from the 1.85-1.95 level that was reached by the 1940-1970 cohorts, to a level of 1.75 or below among women born in the mid-1980s. The tempo-adjusted TFR also suggests that quantum change is driving the decline. These findings are evidence of a strong quantum effect, and are particularly striking because they call into question whether Finland will continue to be part of the Nordic fertility regime, which has been characterized by high and stable fertility.
An improved optimized resource allocation mechanism for web server grid

Grid is dynamic and heterogeneous collection of resources which are located at remote locations to meet the demand of high performance computing. Resource allocation is complex and challenging issue in Grid environment, in which user submits its job through Grid Broker and Grid Broker selects the suitable resource for it. This paper discusses a resource allocation algorithm for heterogeneous jobs submitted by user with set of constraints. Two main metrics are majorly considered in this paper-resource cost and waiting time. The proposed algorithm selects a resource which has least cost, and also reduces the waiting time of each process from the user point of view.
Substance use among high school students in Erbil City, Iraq: prevalence and potential contributing factors.

Background Substance use among adolescents, especially smoking and alcohol consumption, has become a public health concern in the Kurdistan Region, Iraq, in the past 10 years. Aims This study aimed to determine the prevalence of substance use and certain associated factors among high school students in Erbil City, Kurdistan Region, Iraq. Methods A cross-sectional study was conducted using a multistage cluster sampling technique to collect a sample of 3000 students. A modified version of the School Survey on Drug Use from the United Nations Office on Drugs and Crime was used for data collection. Binary logistic regression models were used to identify risk factors for substance use. Results The lifetime prevalence rates of cigarettes smoking, waterpipe smoking and alcohol consumption were 27.6%, 23.6% and 3.7%, respectively. Male gender, age 17-19 years, smoker in the family, and easy accessibility of cigarettes were significantly associated with cigarette smoking. Factors significantly associated with waterpipe smoking were male gender, age 17-19 years, waterpipe smoker in the family, waterpipe smoker friend, and easy accessibility. Male gender, alcohol dependent in the family, alcohol-dependent friend, easy accessibility of alcohol, and low family income were significant predictors of alcohol consumption. Conclusions The prevalence of cigarette smoking and waterpipe use was high in the studied sample. Possible explanations for this finding might be the use of flavoured tobacco associated with aromatic smell, and the misconception that waterpipe smoking is less toxic and addictive than cigarette smoking.
Assessment of Levels, Speciation, and Toxicity of Trace Metal Contaminants in Selected Shallow Groundwater Sources, Surface Runoff, Wastewater, and Surface Water from Designated Streams in Lake Victoria Basin, Uganda

The levels, speciation of elements, and toxicity of selected trace metals as well as other parameters in selected surface water, shallow groundwater sources, landfill leachate, and associated surface runoff in the Lake Victoria basin, Uganda, were studied. The WHO guidelines, Ugandan standards, Canadian guidelines and Swedish EPA were used for assessment. The shallow groundwater was acidic with pH values below 6.5. The pH, dissolved organic carbon, flouride, and sulphate levels for all springs were below the guideline values although 52.8% was contaminated with nitrates while 39% was contaminated with chloride ions. Some surface water samples had levels of major elements, such as iron, chromium, aluminium, and manganese, above the guideline values. Speciation studies showed that 74% of the metal ions was bound to dissolved organic matter in surface water, whereas in landfill leachates, the dominant ionic species was metal hydroxides or fulvic acid bound. Risk analysis based on the Swedish EPA showed varied risks of negative effects in 30%–76% of the sample sites ranging from high to increased risk in surface water, whereas the results from modelling sorption data using the Bio-met tool showed potential risk to toxicity effects of Cu2+, Ni2+, Zn2+, and Pb2+ in 15.3%–30.8% surface water samples and 8.3%–62.5% groundwater samples.
Goal statements in brain injury rehabilitation: A cohort study of client-centredness and relationship with goal outcome

Abstract Background: Currently, there is increasing recognition of the need to use a client-centred approach to goal setting in rehabilitation. However, there is limited research to guide practice with community-dwelling clients with acquired brain injury. An understanding of the characteristics of client-centred goals and the extent to which client-centeredness influences goal outcomes is required. Objective: To examine the relationships between the client-centredness of goals and their characteristics, content, recall and outcomes of client-centred goals in brain injury rehabilitation. Methods: A prospective cohort design study was employed. Participants were 45 clients with brain injury receiving outpatient rehabilitation, who completed measures of client-centredness after goal setting. Each goal was classified according to whether it was specific, measurable, non-jargonistic, and participation-focussed, included a timeframe and was recalled by participants. Results: Participants set 223 goals with 20 clinicians from multiple disciplines. Levels of client-centredness did not differ according to the characteristics, content and recall of goals, with the exception of goal specificity (p < 0.01). Client-centredness was significantly and positively correlated with goal outcomes (p < 0.05). Conclusions: The use of client-centred goals is recommended for improved rehabilitation outcomes. Applying goal documentation criteria does not necessarily mean that goals will be client-centred, and highly specific goal statements may not reflect what is important and meaningful to clients.
(Leveled) Fully Homomorphic Encryption without Bootstrapping

We present a novel approach to fully homomorphic encryption (FHE) that dramatically improves performance and bases security on weaker assumptions. A central conceptual contribution in our work is a new way of constructing leveled, fully homomorphic encryption schemes (capable of evaluating arbitrary polynomial-size circuits of a-priori bounded depth), without Gentry’s bootstrapping procedure. Specifically, we offer a choice of FHE schemes based on the learning with error (LWE) or Ring LWE (RLWE) problems that have 2 λ security against known attacks. We construct the following. (1) A leveled FHE scheme that can evaluate depth-L arithmetic circuits (composed of fan-in 2 gates) using O(λ. L3) per-gate computation, quasilinear in the security parameter. Security is based on RLWE for an approximation factor exponential in L. This construction does not use the bootstrapping procedure. (2) A leveled FHE scheme that can evaluate depth-L arithmetic circuits (composed of fan-in 2 gates) using O(λ2) per-gate computation, which is independent of L. Security is based on RLWE for quasipolynomial factors. This construction uses bootstrapping as an optimization. We obtain similar results for LWE, but with worse performance. All previous (leveled) FHE schemes required a per-gate computation of Ω(λ3.5), and all of them relied on subexponential hardness assumptions. We introduce a number of further optimizations to our scheme based on the Ring LWE assumption. As an example, for circuits of large width (e.g., where a constant fraction of levels have width Ω(λ)), we can reduce the per-gate computation of the bootstrapped version to O(λ), independent of L, by batching the bootstrapping operation. At the core of our construction is a new approach for managing the noise in lattice-based ciphertexts, significantly extending the techniques of Brakerski and Vaikuntanathan [2011b].
Evaluation of genetic variability, heritability, genetic advance and correlation for agronomic and yield components in common bean landraces from South western Kenya

The present study was conducted to estimate the genetic variability, heritability, genetic advance and association among selected agronomic traits of common bean landraces from South western Kenya. The field experiment was conducted using 52 common bean landraces at the Kenya Agricultural and Livestock Research Organization (KALRO), Kisii Research Center during 2015 and 2016 main cropping seasons. The experimental design was randomized complete block (RCBD) with three replications. Analysis of variance revealed significant differences indicating the existence of genetic variability among the 52 landraces for 14 quantitative traits studied. The genotypic coefficient of variation ranged from 1.00% for biological yield to 84.69% for pod width, while the phenotypic coefficient of variation ranged from 2.34% for biological yield to 84.40% for number of branches. The estimated broad sense heritability ranged from 60.20% for seeds per plant to 87.57% for days to emergence. Estimates of genetic advance as percent of mean ranged from 10.15% for biological yield to 97.45% for number of branches. Positive and highly significant association of plant height, days from planting to 50% flowering, number of pods per plant and biological yield was observed with seed yield per plant, hence these traits may be directly attributed for the improvement of seed yield. High hereditability and genetic advance was obtained for plant height, 100 seed weight, pod width and number of branches, indicating additive gene effects in controlling the traits and these traits could be used as suitable criteria for selection and improvement of common bean in breeding programs. Key words: Phaseolus vulgaris, phenotypic variability, genotypic variability, quantitative traits, heritability, genetic advance, breeding.
Economic Load Dispatch—A Comparative Study on Heuristic Optimization Techniques With an Improved Coordinated Aggregation-Based PSO

In this paper an improved coordinated aggregation-based particle swarm optimization (ICA-PSO) algorithm is introduced for solving the optimal economic load dispatch (ELD) problem in power systems. In the ICA-PSO algorithm each particle in the swarm retains a memory of its best position ever encountered, and is attracted only by other particles with better achievements than its own with the exception of the particle with the best achievement, which moves randomly. Moreover, the population size is increased adaptively, the number of search intervals for the particles is selected adaptively and the particles search the decision space with accuracy up to two digit points resulting in the improved convergence of the process. The ICA-PSO algorithm is tested on a number of power systems, including the systems with 6, 13, 15, and 40 generating units, the island power system of Crete in Greece and the Hellenic bulk power system, and is compared with other state-of-the-art heuristic optimization techniques (HOTs), demonstrating improved performance over them.
Degradation of Ecosystem Services and Deforestation in Landscapes With and Without Incentive-Based Forest Conservation in the Ecuadorian Amazon

Anthropogenic activities such as logging or forest conversion into agricultural lands are affecting Ecuadorian Amazon forests. To foster private and communal conservation activities an economic incentive-based conservation program (IFC) called Socio Bosque was established. Existing analyses related to conservation strategies are mainly focused on deforestation; while degradation and the role of IFC to safeguard ecosystem services are still scarce. Further on, there is a lack of landscape-level studies taking into account potential side effects of IFC on different forest types. Therefore we assessed ecosystem services (carbon stocks, timber volume) and species richness in landscapes with and without IFC. Additionally, we evaluated potential side-effects of IFC in adjacent forest types; hypothesizing potential leakage effects of IFC. Finally, we tested if deforestation rates decreased after IFC implementation. Forest inventories were conducted in 72 plots across eight landscapes in the Ecuadorian Central Amazon with and without IFC. Plots were randomly selected within three forest types (old-growth, logged and successional forests). In each plot all individuals with a diameter at breast height greater than 10 cm were measured. Old-growth forests in general showed higher carbon stocks, timber volume and species richness, and no significant differences between old-growth forests in IFC and non-IFC landscapes were found. Logged forests had 32% less above-ground carbon (AGC) and timber volume in comparison to old-growth forests. Surprisingly, logged forests near IFC presented higher AGC stocks than logged forests in non-IFC landscapes, indicating positive side-effects of IFC. Successional forests contain 56% to 64% of AGC, total carbon and timber volume, in comparison to old-growth forests, and 82% to 87% in comparison to logged forests. Therefore, successional forests could play an important role for restoration and should receive more attention in national climate change policies. Finally, after IFC implementation deforestation rate decreased on parish level. Our study presents scientific evidence of IFC contribution to conserving ecosystem services and species richness. In addition IFC could help indirectly to reduce degradation effects attributed to logging, indicating potential compatibility of conservation aims with forest activities at a landscape level.
Magnetic Field in the Martian Magnetosheath and the Application as an IMF Clock Angle Proxy

We present a study of the magnetic field in the Martian magnetosheath using data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission and provide a proxy for the upstream interplanetary magnetic field (IMF) clock angles based on the sheath field directions. The magnetic field data from MAVEN taken in the sheath region are organized in the Mars Solar Electric field coordinate system and sorted by the IMF polarity. The sheath magnetic field distributions clearly illustrate the morphology of draped IMF around the planetary obstacle and show strong asymmetries between the quasi‐perpendicular and quasi‐parallel bow shock quadrants as well as a slight asymmetry between the +E and –E quadrants. We have also studied the effects of different drivers on the strengths and clock angles of the sheath magnetic field and find that the sheath field is strongly affected by upstream IMF and solar wind and that Martian crustal fields also have small contributions to the sheath magnetic field strength. Based on the morphology of the draped field in the sheath, we developed a simple IMF clock angle proxy as the clock angle of the orbital‐averaged sheath magnetic field, which works well under steady IMF conditions. This proxy has an error <44° for 75% of all instances. The uncertainty of the proxy depends on upstream conditions and spacecraft orbit geometry. We also provide estimates of the proxy uncertainty based on sheath magnetic field variability and proxy clock angle.
Are Audit Firms' Compensation Policies Associated with Audit Quality?

We examine how compensation policies of audit firms are associated with audit quality. Specifically, we investigate the effects of the ratio of variable to fixed compensation and the size of the basis for profit sharing (i.e., whether partners share profits in a small or in a large profit pool). For our analyses, we use detailed mandatory disclosure of the compensation policies in German audit firms. We document that compensation policies vary considerably across audit firms. We find that profit sharing in a small profit pool and high variable compensation are two characteristics of auditor compensation associated with lower audit quality. We also find some evidence suggesting that audit quality may be most at risk in cases in which partners rely more heavily on variable compensation to divide a relatively small profit pool. In additional analyses, we find that these associations are more pronounced in medium-sized audit firms. We argue that this finding may result from these firms being too large for audit partners to directly monitor each other effectively, yet simultaneously too small to have sophisticated centralized monitoring systems in place. Finally, we find that integrating partner-specific, non-profit-related performance metrics into the compensation structure mitigates the adverse effects of small profit pools and high variable compensation.
Decoding Binary Linear Codes Using Penalty Dual Decomposition Method

In this letter, we utilize the penalty dual decomposition (PDD) framework and develop a novel PDD decoding algorithm for binary linear codes. Instead of relaxing the discrete constraints to continuous ones, we take an alternative by transforming them into equivalent equality constraints. This idea leads to a double-loop parallel algorithm: In the outer loop, we update the dual variables and certain penalty parameters, while in the inner loop, we divide the primal variables into several blocks and employ the block successive upper-bound minimization method to iteratively optimize each block variable in closed form. Every limit point generated by the proposed algorithm is guaranteed to be a stationary point of the maximum likelihood decoding problem. Simulation results demonstrate that the proposed algorithm shows great error rate performance at both low and high signal-to-noise ratios.
How social networking site addiction drives university students’ academic achievement: The mediating role of learning engagement

The main aim of this study was to explore the mediating role of learning engagement on the relationship between social networking site (SNS) addiction and academic achievement among 406 university students. The Social Networking Site Addiction Scale, Utrecht Work Engagement Scale for Students, and Chinese Students Academic Achievement Scale were used to evaluate students’ SNS addiction, learning engagement, and academic achievement. Correlation analysis indicated that SNS addiction, learning engagement, and academic achievement were significantly correlated with each other. The causal steps regression and bootstrap analysis show that learning engagement mediated the relationship between SNS addiction and academic achievement. Implications for research and instructions for how to improve university students’ academic achievement are discussed.
A Novel Technique of Repair of Congenital Left Atrial Appendage Aneurysm using Bovine Pericardial Patch

A congenital left atrial appendage aneurysm is a rare cause of supraventricular arrhythmias and dyspnea in young adult. Resection of the aneurysm is uniformly recommended in order to prevent life-threatening systemic embolization. We describe here in a new technique of resection of the congenital left atrial appendage aneurysm and anatomical reconstruction using a bovine pericardial patch under cardiopulmonary bypass, permitting us to avoid under sizing and deformation of the left atrium.
A survey of tobacco dependence treatment services in 36 countries.

AIMS This paper reports the results of a survey of national tobacco dependence treatment services in 36 countries. The objective was to describe the services and discuss the results in the context of Article 14 of the Framework Convention on Tobacco Control, which asks countries to promote adequate treatment for tobacco dependence. DESIGN, SETTING AND PARTICIPANTS A questionnaire on tobacco dependence treatment services was e-mailed to a convenience sample of contacts in 2007. Completed questionnaires were received from contacts in 36 countries. MEASUREMENTS The survey instrument was a 10-item questionnaire asking about treatment policy and practice, including medications. FINDINGS According to our informants, fewer than half the countries in our survey had an official written policy on (44%), or a government official responsible for (49%), treatment. Only 19% had a specialized national treatment system and only 24% said help was easily available in general practice. Most countries (94%) allowed the sale of nicotine replacement therapy (NRT), bupropion (75%) and varenicline (69%) but only 40% permitted NRT on 'general sale'. Very few countries responding to the question fully reimbursed any of the medications. Fewer than half (45%) fully reimbursed brief advice and only 29% fully reimbursed intensive specialist support. Only 31% of countries said that their official treatment policy included the mandatory recording of patients' smoking status in medical notes. CONCLUSION Taken together, our findings show that few countries have well-developed tobacco dependence treatment services and that, at a national level, treatment is not yet a priority in most countries.
Routine Reporting of Environmental Risk: The First Traces of Micropollutants in the German Press

ABSTRACT This article analyzes the emergence of a new environmental issue in the German press. Since the 1990s, scientists have detected traces of pharmaceuticals, hormones and chemicals in all segments of the water cycle. These micropollutants have negative effects on aquatic life and might affect human health. Their sources are manifold and include private households. Yet although micropollutants of are direct concern to media audiences, they are a challenging topic for news reporting. Although this issue is systemic and fraught with uncertainty, it does not easily translate into news stories. Our content analysis of 444 articles (1995–2015) reveals that the societal risk was rarely presented as a stand-alone topic. Instead, the issue was mostly covered as part of local routine reporting and framed as a challenge for experts to solve. Over time, the reporting became more managerial, while media framings of micropollutants gained more substance and scope. We contend that local routine reporting should receive more attention as a public forum for addressing emerging environmental concerns.
