A review of contraceptive practices among married and unmarried women in China from 1982 to 2010.

OBJECTIVE
To analyse the contraceptive prevalence rate (CPR) among - and contraceptive methods used by - married and unmarried women in China, from 1982 to 2010.


METHOD
Data concerning married women were collected from national surveys conducted by the Chinese government. Those pertaining to unmarried women were obtained by searching the China Academic Journal Network Publishing database and PubMed.


RESULTS
CPR among married women in China was 89% in 2010, the highest in the world. Most married women use long-acting reversible contraceptives, particularly intrauterine devices, and sterilisation. CPR among sexually active unmarried women has fluctuated between 17 and 70% since 1988, although the frequency of condom use has increased (Cochran-Armitage trend test, χ(2) = 126.1, p < 0.001). More than 25% of unmarried women rely since at least 1982 on less effective contraceptive methods, including rhythm and withdrawal. This has led to an annual induced abortion rate of approximately 20% among those women.


CONCLUSION
In sharp contrast to the high CPR among married women, the rate among sexually active unmarried women in China has remained extremely low since 1988. More efforts should be directed at raising contraception awareness among this population to improve their reproductive health and reduce the rate of unwanted pregnancy.
Returning from the Horizon: Introducing Urban Island Studies

Island studies tends to focus on peripheral, isolated, and marginal aspects of island communities, while urban studies has showed scant awareness of islandness: Although many people research cities on islands, there is little tradition of researching island cities or urban archipelagos per se. Island cities (densely populated small islands and population centres of larger islands and archipelagos) nevertheless play import cultural, economic, political, and environmental roles on local, regional, and global scales. Many major cities and ports have developed on small islands, and even villages can fulfil important urban functions on lightly populated islands. Island concepts are also deployed to metaphorically describe developments in urban space. The journal Urban Island Studies explores island and urban processes around the world, taking an island approach to urban research and an urban approach to island research.
Dynapenic obesity and the effect on long-term physical function and quality of life: data from the osteoarthritis initiative

BACKGROUND
Obesity is associated with functional impairment, institutionalization, and increased mortality risk in elders. Dynapenia is defined as reduced muscle strength and is a known independent predictor of adverse events and disability. The synergy between dynapenia and obesity leads to worse outcomes than either independently. We identified the impact of dynapenic obesity in a cohort at risk for and with knee osteoarthritis on function.


METHODS
We identified adults aged ≥ 60 years from the Osteoarthritis Initiative. Obesity was defined as a body mass index ≥ 30 kg/m(2). Dynapenia was classified using the lowest sex-specific tertile of knee extensor strength. Participants were grouped according to obesity and knee strength: dynapenic obesity; dynapenia without obesity; obesity without dynapenia; and no dynapenia nor obesity. Four-year data was available. Self-reported activities of daily living (ADL) were assessed at follow-up. Outcomes of gait speed, 400 m walk distance, Late-life Disability and Function Index (LLFDI), and Short-Form (SF)-12 were analyzed using mixed effects and logistic regression models.


RESULTS
Of 2025 subjects (56.3 % female), mean age was 68.2 years and 182 (24.1 %) had dynapenic obesity. Dynapenic obesity was associated with reduced gait speed, LLFDI-limitations, and SF-12 physical score in both sexes and in the 400 m walk in men only (all p < 0.001). A time*group interaction was significant for dynapenic obese men in the 400 m walk distance only. Odds of ADL limitations in dynapenic obesity was OR 2.23 [1.42:3.50], in dynapenia 0.98 [0.66:1.46], and in obesity 1.98 [1.39:2.80] in males. In females, odds were 2.45 [1.63:3.68], 1.60 [1.15:2.22], and 1.47 [1.06:2.04] respectively.


CONCLUSION
Dynapenic obesity may be a risk factor for functional decline suggesting the need to target subjects with low knee strength and obesity.
Antibacterial Potential of Northeastern Portugal Wild Plant Extracts and Respective Phenolic Compounds

The present work aims to assess the antibacterial potential of phenolic extracts, recovered from plants obtained on the North East of Portugal, and of their phenolic compounds (ellagic, caffeic, and gallic acids, quercetin, kaempferol, and rutin), against bacteria commonly found on skin infections. The disk diffusion and the susceptibility assays were used to identify the most active extracts and phenolic compounds. The effect of selected phenolic compounds on animal cells was assessed by determination of cellular metabolic activity. Gallic acid had a higher activity, against gram-positive (S. epidermidis and S. aureus) and gram-negative bacteria (K. pneumoniae) at lower concentrations, than the other compounds. The caffeic acid, also, showed good antibacterial activity against the 3 bacteria used. The gallic acid was effective against the 3 bacteria without causing harm to the animal cells. Gallic and caffeic acid showed a promising applicability as antibacterial agents for the treatment of infected wounds.

Adaptation of Bird Communities to Farmland Abandonment in a Mountain Landscape

Widespread farmland abandonment has led to significant landscape transformations of many European mountain areas. These semi-natural multi-habitat landscapes are important reservoirs of biodiversity and their abandonment has important conservation implications. In multi-habitat landscapes the adaptation of communities depends on the differential affinity of the species to the available habitats. We use nested species-area relationships (SAR) to model species richness patterns of bird communities across scales in a mountain landscape, in NW Portugal. We compare the performance of the classic-SAR and the countryside-SAR (i.e. multi-habitat) models at the landscape scale, and compare species similarity decay (SSD) at the regional scale. We find a considerable overlap of bird communities in the different land-uses (farmland, shrubland and oak forest) at the landscape scale. Analysis of the classic and countryside SAR show that specialist species are strongly related to their favourite habitat. Farmland and shrubland have higher regional SSD compared to oak forests. However, this is due to the opportunistic use of farmlands by generalist birds. Forest specialists display significant regional turnover in oak forest. Overall, the countryside-SAR model had a better fit to the data showing that habitat composition determines species richness across scales. Finally, we use the countryside-SAR model to forecast bird diversity under four scenarios of land-use change. Farmland abandonment scenarios show little impact on bird diversity as the model predicts that the complete loss of farmland is less dramatic, in terms of species diversity loss, than the disappearance of native Galicio-Portuguese oak forest. The affinities of species to non-preferred habitats suggest that bird communities can adapt to land-use changes derived from farmland abandonment. Based on model predictions we argue that rewilding may be a suitable management option for many European mountain areas.
The Good, the Bad, or the Useful? The Examination of the Relationship between the Feedback-related Negativity (FRN) and Long-term Learning Outcomes

According to the reinforcement learning account of the error-related negativity (ERN), the ERN is a manifestation of a signal generated in ACC as a consequence of a phasic decrease in the activity of the mesencephalic dopamine system occurring when the monitoring system evaluates events as worse than expected. This signal is also hypothesized to be used to modify behavior to ascertain that future events will have better outcomes. It is therefore expected that this signal be correlated with learning outcomes. We report a study designed to examine the extent to which the ERN is related to learning outcomes within a paired-associates learning task. The feedback-related negativity (FRN) elicited by stimuli that indicated to the participants whether their response was correct or not was examined both according the degree to which the associates were learned in the session and according to whether participants recalled the associations on the next day. The results of the spatio-temporal PCA indicate that, whereas the process giving rise to the negative feedback elicited a FRN whose amplitude was not correlated with long-term learning outcomes, positive feedback was associated with a FRN-like activity, which was correlated with the learning outcomes. Another ERP component that follows the FRN temporally and shares its spatial distribution was found associated with long-term learning outcomes. Our findings shed light on the functional significance of the feedback-related ERP components and are discussed within the framework of the reinforcement learning ERN hypothesis.
Tilapia Production Systems in the Americas: Technological Advances, Trends, and Challenges

Tilapia is the common name applied to three genera of fish in the family Cichlidae: Oreochromis, Sarotherodon, and Tilapia. The species that are most important for aquaculture are in the genus Oreochromis, including the Nile tilapia, O. niloticus, the Mozambique tilapia, O. mossambicus, the blue tilapia, O. aureus, and O. urolepis hornorum. Fish farmers are now growing many strains of these parent species along with many hybrid strains. Native to Africa and the Middle East, these species have become the second most common farm raised food fish in the world. In the 1960s and 1970s tilapia culture was aimed at the production of food for local consumption, utilizing primarily extensive or semiintensive culture methods with minimal inputs of fertilizer or feeds. However, tilapia culture has expanded rapidly during the last decade as a result of technological advances associated with the intensification of culture practices. These include the development of new strains and hybrids, monosex male culture, formulated diets, a variety of semiintensive and intensive culture systems (e.g., ponds, cages, tanks, and raceways) and the utilization of greenhouses, geothermal, or industrial waste heat and advanced water treatment methods. Marketing programs have also nurtured a growing demand for tilapia in domestic and international markets. Annual worldwide production of cultured tilapia was less than 200,000 metric tons (mt) in 1984 and increased to 1,100,000 mt
Phase I study of NGR-hTNF, a selective vascular targeting agent, in combination with cisplatin in refractory solid tumors.

PURPOSE
NGR-hTNF exploits the tumor-homing peptide asparagine-glycine-arginine (NGR) for selectively targeting TNF-α to an aminopeptidase N overexpressed on cancer endothelial cells. Preclinical synergism with cisplatin was displayed even at low doses. This study primarily aimed to explore the safety of low-dose NGR-hTNF combined with cisplatin in resistant/refractory malignancies. Secondary aims included pharmacokinetics (PKs), pharmacodynamics, and activity.


EXPERIMENTAL DESIGN
NGR-hTNF was escalated using a doubling-dose scheme (0.2-0.4-0.8-1.6 μg/m(2)) in combination with fixed-dose of cisplatin (80 mg/m(2)), both given intravenously once every three weeks. PKs and circulating TNF-receptors (sTNF-Rs) were assessed over the first three cycles.


RESULTS
Globally, 22 patients (12 pretreated with platinum) received a range of one to ten cycles. Consistently with the low-dose range tested, maximum-tolerated dose was not reached. No dose-limiting toxicities (DLTs) were observed at 0.2 (n = 4) and 0.4 μg/m(2) (n = 3). One DLT (grade 3 infusion-related reaction) was observed at 0.8 μg/m(2). This dose cohort was expanded to six patients without further DLTs. No DLTs were noted also at 1.6 μg/m(2) (n = 3). NGR-hTNF exposure increased dose-proportionally without apparent PK interactions with cisplatin. No shedding of sTNF-Rs was detected up to 0.8 μg/m(2). At the dose level of 0.8 μg/m(2), expanded to 12 patients for activity assessment, a platinum-pretreated lung cancer patient achieved a partial response lasting more than six months and five patients maintained stable disease for a median time of 5.9 months.


CONCLUSIONS
The combination of NGR-hTNF 0.8 μg/m(2) with cisplatin 80 mg/m(2) showed favorable toxicity profile and promising antitumor activity.
Adaptive graph filtering: Multiresolution classification on graphs

We present an adaptive graph filtering approach to semi-supervised classification. Adaptive graph filters combine decisions from multiple graph filters using a weighting function that is optimized in a semi-supervised manner. We also demonstrate the multiresolution property of adaptive graph filters by connecting them to the diffusion wavelets. In our experiments, we apply the adaptive graph filters to the classification of online blogs and damage identification in indirect bridge structural health monitoring.
TWO FIXED-POINT THEOREMS FOR MAPPINGS SATISFYING A GENERAL CONTRACTIVE CONDITION OF INTEGRAL TYPE

We establish two fixed-point theorems for mappings satisfying a general contrac-tive inequality of integral type. These results substantially extend the theorem of Branciari (2002). In a recent paper [1], Branciari established the following theorem. Theorem 1. Let (X, d) be a complete metric space, c ∈ [0, 1), f : X → X a mapping such that, for each x, y ∈ X, d(f x,f y) 0 ϕ(t)dt ≤ c d(x,y) 0 ϕ(t)dt, (1) where ϕ : R + → R + is a Lebesgue-integrable mapping which is summable, non-negative, and such that, for each > 0, 0 ϕ(t)dt > 0. Then f has a unique fixed point z ∈ X such that, for each x ∈ X, lim n f n x = z. In [1], it was mentioned that (1) could be extended to more general contrac-tive conditions. It is the purpose of this paper to make such an extension to two of the most general contractive conditions. Define m(x, y) = max d(x,y),d(x,f x),d(y,f y), d(x, f y) + d(y, f x) 2. (2) Our first result is the following theorem. Theorem 2. Let (X, d) be a complete metric space, k ∈ [0, 1), f : X → X a mapping such that, for each x, y ∈ X, d(f x,f y) 0 ϕ(t)dt ≤ k m(x,y) 0 ϕ(t)dt, (3)
Dietary intakes and lifestyle factors of a vegan population in Germany: results from the German Vegan Study

Objective: Evaluation of dietary intakes and lifestyle factors of German vegans.Design: Cross-sectional study.Settings: Germany.Subjects: Subjects were recruited through journal advertisements. Of 868 volunteers, only 154 participated in all study segments (pre- and main questionnaire, two 9-day food frequency questionnaires, blood sampling) and fulfilled the following study criteria: vegan dietary intake at least 1 year prior to study start, minimum age of 18 y, no pregnancy or childbirth during the last 12 months.Interventions: No interventions.Results: All the 154 subjects had a comparatively low BMI (median 21.2 kg/m2), with an extremely low mean consumption of alcohol (0.77±3.14 g/day) and tobacco (96.8% were nonsmokers). Mean energy intake (total collective: 8.23±2.77 MJ) was higher in strict vegans than in moderate ones. Mean carbohydrate, fat, and protein intakes in proportion to energy (total collective: 57.1:29.7:11.6%) agreed with current recommendations. Recommended intakes for vitamins and minerals were attained through diet, except for calcium (median intake: 81.1% of recommendation), iodine (median: 40.6%), and cobalamin (median: 8.8%). For the male subgroup, the intake of a small amount of food of animal origin improved vitamin and mineral nutrient densities (except for zinc), whereas this was not the case for the female subgroup (except for calcium).Conclusion: In order to reach favourable vitamin and mineral intakes, vegans should consider taking supplements containing riboflavin, cobalamin, calcium, and iodine. Intake of total energy and protein should also be improved.Sponsorship: EDEN Foundation, Bad Soden, Germany; Stoll VITA Foundation, Waldshut-Tiengen, Germany
Family environment of children and adolescents with bipolar parents.

OBJECTIVES
The effect of family environment on the development of bipolar disorder (BD) in children is not known. We sought to characterize families with children at high risk for developing BD in order to better understand the contributions of family environment to the development of childhood BD.


METHODS
We collected demographic data and parental ratings on the Family Environment Scale (FES) for 56 children (aged 6-18 years) from 36 families with at least one biological parent with BD. The cohort had previously been psychiatrically diagnosed according to semistructured interviews.


RESULTS
Statistical comparisons with normative data indicated that parents' ratings were significantly lower on the FES Cohesion and Organization scales and were significantly higher on the FES Conflict scale. Multivariate analyses of variance indicated that families with both parents having a mood disorder had no significantly different FES scores than families with only one parent with a mood disorder (BD). Diagnostic data indicated that while 54% of the children in the sample had an Axis I disorder and 14% had BD, FES scores did not differ significantly for subjects with or without an Axis I disorder, or with or without BD.


CONCLUSIONS
Families with a bipolar parent differ from the average family in having less cohesion and organization, and more conflict. Despite this difference, it does not appear that the environment alone of families with a bipolar parent determines the outcome of psychopathology in the children, or that the psychopathology of the children determines the family environment.
Removal of heavy metals by an Aspergillus terreus strain immobilized in a polyurethane matrix.

AIMS
The aim was to investigate the biosorption of chromium, nickel and iron from metallurgical effluents, produced by a steel foundry, using a strain of Aspergillus terreus immobilized in polyurethane foam.


METHODS AND RESULTS
A. terreus UFMG-F01 was immobilized in polyurethane foam and subjected to biosorption tests with metallurgical effluents. Maximal metal uptake values of 164.5 mg g(-1) iron, 96.5 mg g(-1) chromium and 19.6 mg g(-1) nickel were attained in a culture medium containing 100% of effluent stream supplemented with 1% of glucose, after 6 d of incubation.


CONCLUSIONS
Microbial populations in metal-polluted environments include fungi that have adapted to otherwise toxic concentrations of heavy metals and have become metal resistant. In this work, a strain of A. terreus was successfully used as a metal biosorbent for the treatment of metallurgical effluents.


SIGNIFICANCE AND IMPACT OF THE STUDY
A. terreus UFMG-F01 was shown to have good biosorption properties with respect to heavy metals. The low cost and simplicity of this technique make its use ideal for the treatment of effluents from steel foundries.
Test Scaling and Value-Added Measurement

Conventional value-added assessment requires that achievement be reported on an interval scale. While many metrics do not have this property, application of item response theory (IRT) is said to produce interval scales. However, it is difficult to confirm that the requisite conditions are met. Even when they are, the properties of the data that make a test IRT scalable may not be the properties we seek to represent in an achievement scale, as shown by the lack of surface plausibility of many scales resulting from the application of IRT. An alternative, ordinal data analysis, is presented. It is shown that value-added estimates are sensitive to the choice of ordinal methods over conventional techniques. Value-added practitioners should ask themselves whether they are so confident of the metric properties of these scales that they are willing to attribute differences to the superiority of the latter.
