Rates and drivers of mangrove deforestation in Southeast Asia, 2000-2012.

The mangrove forests of Southeast Asia are highly biodiverse and provide multiple ecosystem services upon which millions of people depend. Mangroves enhance fisheries and coastal protection, and store among the highest densities of carbon of any ecosystem globally. Mangrove forests have experienced extensive deforestation owing to global demand for commodities, and previous studies have identified the expansion of aquaculture as largely responsible. The proportional conversion of mangroves to different land use types has not been systematically quantified across Southeast Asia, however, particularly in recent years. In this study we apply a combined geographic information system and remote sensing method to quantify the key proximate drivers (i.e., replacement land uses) of mangrove deforestation in Southeast Asia between 2000 and 2012. Mangrove forests were lost at an average rate of 0.18% per year, which is lower than previously published estimates. In total, more than 100,000 ha of mangroves were removed during the study period, with aquaculture accounting for 30% of this total forest change. The rapid expansion of rice agriculture in Myanmar, and the sustained conversion of mangroves to oil palm plantations in Malaysia and Indonesia, are identified as additional increasing and under-recognized threats to mangrove ecosystems. Our study highlights frontiers of mangrove deforestation in the border states of Myanmar, on Borneo, and in Indonesian Papua. To implement policies that conserve mangrove forests across Southeast Asia, it is essential to consider the national and subnational variation in the land uses that follow deforestation.
Haemodynamic changes during early bereavement: potential contribution to increased cardiovascular risk.

BACKGROUND
bereavement is associated with increased cardiovascular risk, particularly in surviving spouses and parents, however the mechanism is not well understood due to limited studies. The purpose of this study was to evaluate haemodynamic changes (blood pressure (BP) and heart rate (HR)), that may contribute to increased cardiac risk in early bereavement.


METHODS
we enrolled 80 bereaved individuals and 80 non-bereaved as a reference group. Twenty-four hour ambulatory blood pressure monitoring was performed within two weeks (acute assessment) and at six months following bereavement.


RESULTS
compared to the non-bereaved, the acutely bereaved had higher 24-hour systolic BP (mean (SE) 130.3 (1.5) vs 127.5 (1.4)mmHg, p=0.03), higher daytime systolic BP (135.6 (1.5) vs 131.6 (1.4)mmHg, p=0.02) and higher daytime systolic load (median % 39.0 vs 29.3, p=0.02). By six months the BP of the bereaved tended to be lower than acute measures. This difference was significant amongst those not taking BP lowering medications for 24-hour systolic BP (126.5 (2.4) vs 129.7 (2.3)mmHg, p=0.04), daytime systolic BP (129.8 (2.1) vs 133.9 (2.0)mmHg, p=0.01) and daytime diastolic pressure (76.7 (1.0) vs 78.9 (0.9)mmHg, p=0.03). Twenty-four hour heart rate was also higher acutely in the bereaved compared with the reference group (74.0 (1.2) vs 71.7 (0.9) b/min, p=0.02); at six months heart rate in the bereaved had fallen to non-bereaved levels (70.4 (0.09), p=0.02).


CONCLUSION
early bereavement is associated with increased systolic blood pressure and heart rate. These haemodynamic changes may contribute to a time-limited increase in cardiovascular risk.
Human nutrition, the gut microbiome and the immune system

Marked changes in socio-economic status, cultural traditions, population growth and agriculture are affecting diets worldwide. Understanding how our diet and nutritional status influence the composition and dynamic operations of our gut microbial communities, and the innate and adaptive arms of our immune system, represents an area of scientific need, opportunity and challenge. The insights gleaned should help to address several pressing global health problems.
An Ontology Engineering Approach For Knowledge Discovery From Data In Evolving Domains

Knowledge discovery in evolving domains presents several challenges in information extraction and knowledge acquisition from heterogeneous, distributed, dynamic data sources. We define an evolving process if the process is developing, changing over time in a continuous manner. Examples of such domains include biological sciences, medical sciences, and social sciences, among others. This paper describes research in progress on a new methodology for leveraging the semantic content of ontologies to improve knowledge discovery in complex and dynamical domains. We consider in this initial stage the problem of how to acquire previous knowledge from data and then use this information in the context of ontology engineering. The first part of this paper concerns some aspects that help to understand the differences and similarities between ontologies and data models , followed by an analysis of some of the methods and ongoing researches in the process of building ontology from databases in evolving domains, or ontology learning from databases. In the second part we describe our approach to build a framework able to enhance ontology learning and discovery from data and present future directions of our research integrating ontology and evolving connectionist systems that is being developed in the Knowledge Engineering & Discovery Research Institute -Kedri.
Inborn errors of metabolism and motor disturbances in children

Motor disturbances are very common in paediatric neurology. Often families can be reassured that these are just variants of normal development. However, abnormal movements can also be the hallmark of severe brain dysfunction of different and complex origins. This review concentrates on motor disturbances as frequent and important symptoms of inborn errors of metabolism. A structured diagnostic approach is developed taking into account age-dependent physiological developments and pathophysiological responses of gross and fine motor functions. A series of investigations are presented with the primary aim of early diagnosis of treatable conditions. The correct recognition and differentiation of movement disorders (ataxia, rigid akinetic syndrome (‘parkinsonism’), dystonia, athetosis, tremor, and others), spasticity, and neuromuscular disorders, requires profound neurological expertise. A high level of suspicion and close interaction between paediatric neurologists and specialists in inborn errors of metabolism are indispensable to effectively and timely identify patients in whom motor disturbances are the presenting and/or main symptom of an inborn error.
Mapping genes for NIDDM. Design of the Finland-United States Investigation of NIDDM Genetics (FUSION) Study.

OBJECTIVE
To map and identify susceptibility genes for NIDDM and for the intermediate quantitative traits associated with NIDDM.


RESEARCH DESIGN AND METHODS
We describe the methodology and sample of the Finland-United States Investigation of NIDDM Genetics (FUSION) study. The whole genome search approach is being applied in studies of several different ethnic groups to locate susceptibility genes for NIDDM. Detailed description of the study materials and designs of such studies are important, particularly when comparing the findings in these studies and when combining different data sets.


RESULTS
Using a careful selection strategy, we have ascertained 495 families with confirmed NIDDM in at least two siblings and no history of IDDM among the first-degree relatives. These families were chosen from more than 22,000 NIDDM patients, representative of patients with NIDDM in the Finnish population. In a subset of families, a spouse and offspring were sampled, and they participated in a frequently sampled intravenous glucose tolerance test (FSIGT) analyzed with the Minimal Model. An FSIGT was completed successfully for at least two nondiabetic offspring in 156 families with a confirmed nondiabetic spouse and no history of IDDM in first-degree relatives.


CONCLUSIONS
Our work demonstrates the feasibility of collecting a large number of affected sib-pair families with NIDDM to provide data that will enable a whole genome search approach, including linkage analysis.
Characterization and Carcinogenic Risk Assessment of Polycyclic Aromatic Hydrocarbons in the Respirable Fraction of Airborne Particles in the Bangkok Metropolitan Area

Polycyclic aromatic hydrocarbons (PAHs) are the principal pollutants from incomplete combustion, and are of special interest due to their toxicity, carcinogenicity, and ubiquitous presence in the environment. Major PAH sources to the atmosphere include motor vehicles, home heating, fossil fuel combustion in energy and industrial processes, biomass burning, and municipal and medical incinerators. Ambient atmospheric PAH concentrations vary greatly with high concentrations most often found in urban areas and low concentrations in rural and remote regions. The association of PAH with the respirable fraction of airborne particle matter is of particular importance in terms of human health effects. Furthermore, ambient urban air levels of PAH are of concern because they are produced from the combustion of fossil fuels. In this study, an investigation on airborne particle PAH was conducted in metropolitan Bangkok. Metropolitan Bangkok is the largest city in Thailand with a population of about 10 million. As in other large cities, Bangkok is faced with serious air quality problems. Particles matter equal to or less than 10 μm in diameter (PM10) often exceeds the Thai ambient air quality standard of 120 μg/m over a 24 hr period. Major sources of particulate matter have been attributed to construction activities and motor vehicle traffic. This severe situation suggests air pollution control technologies currently in use may be ineffective for inhaled particles. Various issues have been investigated recently to mitigate air quality concerns in Bangkok. Studies that focus on carcinogenic substances such as PAHs in inhaled particles are still scare in Thailand and other Asean countries, even through Characterization and Carcinogenic Risk Assessment of Polycyclic Aromatic Hydrocarbons in the Respirable Fraction of Airborne Particles in the Bangkok Metropolitan Area
Constructing Gay and Lesbian Parent Families "Beyond the Closet"

This paper provides a multilayered analysis of how lesbian mothers and gay fathers construct their families in a social context that has been described by Steven Seidman (2004) as “beyond the closet.” We stress how our participants’ family-building experiences are comparable to other non-biologically related families, but distinct due to heterosexual dominance. Using in-depth qualitative interviews with 18 lesbian birth mothers and 22 gay fathers, the authors discuss how participants navigate heterosexual dominance in institutions and in personal interactions.
Effects of Campomanesia xanthocarpa on biochemical, hematological and oxidative stress parameters in hypercholesterolemic patients.

ETHNOPHARMACOLOGICAL RELEVANCE
In Southern Brazil, the plant Campomanesia xanthocarpa Berg. (Myrtaceae), popularly known as "guavirova", has been empirically used for its potential effect in reducing blood cholesterol levels.


AIM OF THE STUDY
Since there are no scientific data confirming its popular use, the aim of the present study was to investigate the effect of Campomanesia xanthocarpa on biochemical, hematological, anthropometrical and oxidative stress parameters in hypercholesterolemic patients.


MATERIALS AND METHODS
Thirty three patients were selected according to total cholesterol (TC) levels: 200-240 mg/dL, undesirable level (UL), and >240 mg/dL, hypercholesterolemic level (HL). UL or HL patients were randomly divided into control group (CG), which received placebo capsules, and experimental group 250 (EG 250) or 500 (EG 500), which received either 250 or 500 mg of encapsulated Campomanesia xanthocarpa. All groups received a cholesterol restriction diet and capsules once a day. The biochemical (TC, triglycerides, HDL, LDL and VLDL), hematological (hematocrit and hemoglobin), anthropometrical (weight and abdominal circumference) and oxidative stress (protein carbonyl) parameters were measured before, 45 and 90 days after the treatment started.


RESULTS
There was no alteration on biochemical, hematological, anthropometric or oxidative stress parameters in UL patients of all groups. However, a significant decrease in TC and LDL levels was observed in HL patients from EG 500 group (reduction of 28+/-3% and 45+/-4% to levels before treatment) in relation to CG group patients (reduction of 12+/-2% and 29+/-4%). Moreover, a significant reduction in oxidative stress was observed in HL patients of EG 250 (51+/-12%) and EG 500 groups (34+/-18%) when compared to levels before treatment. A positive correlation between plasma oxidative stress PC and TC levels was observed. Finally, we found that Campomanesia xanthocarpa extract possesses anti-oxidant properties and 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitory activity in vitro.


CONCLUSION
Confirming its popular use, the treatment with Campomanesia xanthocarpa encapsulated reduced blood TC and LDL levels in hypercholesterolemic patients.
Understanding User Profiles on Social Media for Fake News Detection

Consuming news from social media is becoming increasingly popular nowadays. Social media brings benefits to users due to the inherent nature of fast dissemination, cheap cost, and easy access. However, the quality of news is considered lower than traditional news outlets, resulting in large amounts of fake news. Detecting fake news becomes very important and is attracting increasing attention due to the detrimental effects on individuals and the society. The performance of detecting fake news only from content is generally not satisfactory, and it is suggested to incorporate user social engagements as auxiliary information to improve fake news detection. Thus it necessitates an in-depth understanding of the correlation between user profiles on social media and fake news. In this paper, we construct real-world datasets measuring users trust level on fake news and select representative groups of both “experienced” users who are able to recognize fake news items as false and “naïve” users who are more likely to believe fake news. We perform a comparative analysis over explicit and implicit profile features between these user groups, which reveals their potential to differentiate fake news. The findings of this paper lay the foundation for future automatic fake news detection research.
Prevalence of eosinophilia in hospitalized patients with asthma exacerbation.

BACKGROUND
Recent studies have identified the "eosinophilic phenotype" of asthma that is characterized by persistent eosinophilic inflammation and frequent exacerbations. However, the prevalence of eosinophilia in patients hospitalized for asthma exacerbation is not known.


METHODS
We performed a pilot study in two sites participating in a multicenter chart review project of children and adults hospitalized for asthma exacerbation during 2012-2013. The pilot study investigated the prevalence of blood eosinophilia in this patient population. Eosinophilia was defined as a count of ≥300 cells/microliter at some time during the hospitalization.


RESULTS
Among 80 patients hospitalized for asthma exacerbation, 47 (59%) underwent CBC with differential and had data on blood eosinophil count. These 47 comprised the analytic cohort. The median patient age was 32 years (IQR, 24-44 years), and 51% were female. Overall, 40% (95% CI, 26%-56%) of patients had eosinophilia. Although statistical power was limited, there were no statistically significant differences in patient characteristics or hospital course between patients with eosinophilia and those without (all P > 0.05).


CONCLUSION
Our pilot study showed that 40% of patients hospitalized for asthma exacerbation had eosinophilia. The clinical meaning of this biomarker in the emergency department/inpatient setting requires further study in much larger samples with long-term follow-up; such studies appear feasible.
Breast imaging: is the sonographic descriptor of orientation valid for magnetic resonance imaging?

PURPOSE
To evaluate if the Breast Imaging Reporting and Data System (BI-RADS) ultrasound descriptor of orientation can be used in magnetic resonance imaging (MRI).


MATERIALS AND METHODS
We conducted a retrospective study to evaluate breast mass lesions identified by MRI from 2008 to 2010 who had ultrasound (US) and histopathologic confirmation. Lesions were measured in the craniocaudal (CC), anteroposterior (AP), and transverse (T) axes and classified as having a nonparallel orientation, longest axis perpendicular to Cooper's ligaments, or in a parallel orientation when the longest axis is parallel to Cooper's ligaments. The MR image data were correlated with the US orientation according to BI-RADS and histopathological diagnosis.


RESULTS
We evaluated 71 lesions in 64 patients. On MRI, 27 lesions (38.0%) were nonparallel (8 benign and 19 malignant), and 44 lesions (62.0%) were parallel (33 benign and 11 malignant). There was significant agreement between the lesion orientation on US and MRI (kappa value = 0.901). The positive predictive values (PPV) for parallel orientation malignancy on MR and US imaging were 70.4% and 73.1%, respectively.


CONCLUSION
A descriptor of orientation for breast lesions can be used on MRI with PPV for malignant lesions similar to US.
Research Frontiers in the Economics of Climate Change

Academic and policy debates over climate change risks and policies have stimulated economic research in a variety of fields. In this article I briefly discuss eight overlapping areas of current research in which further effort particularly is warranted. These areas include decision criteria for policy; risk assessment and adaptation; uncertainty and learning; abatement cost and the innovation and diffusion of technology; and the credibility of policies and international agreements. Further analysis in these areas not only will advance academic understanding but also will provide insights of considerable importance to policymakers.
Joint Topology Control and Authentication Design in Mobile Ad Hoc Networks With Cooperative Communications

Security is the main concern and bottleneck for widely deployed wireless applications due to the fact that wireless channels are vulnerable to attacks and that wireless bandwidth is a constrained resource. In this sense, it is desirable to adaptively achieve security according to the available resource. In particular, mobile ad hoc networks (MANETs) based on cooperative communication (CC) present significant challenges to security issues, as well as issues of network performance and management. In this paper, we focus on authentication and topology control issues. Although authentication and topology control are separately studied in most existing works, they are, in fact, closely correlated in MANETs. For example, both authentication and topology control schemes have significant impacts on throughput. In this paper, we jointly consider authentication and topology control. Specifically, we analyze the effective throughput with upper layer authentication schemes and physical-layer schemes related to channel conditions and relay selections for CCs. A joint authentication and topology control (JATC) scheme is proposed to improve the throughput. JATC is formulated as a discrete stochastic optimization problem, which does not require prior perfect channel status but only channel estimate. We also mathematically prove the tracking convergence property and the convergence rate of the discrete stochastic optimization approach in this paper. Simulation results show that our scheme can substantially improve throughput in MANETs with CC.
Randomised study versus control group of customised therapeutic education for patients in follow-up for rheumatoid arthritis.

OBJECTIVE
We have evaluated customized objectives, predefined during a therapeutic education session for rheumatoid arthritis (RA).


METHODS
Fifty-four RA patients were randomised into patient therapeutic education (PTE) group versus waiting list (WL). The final comparative evaluation involved solving 3 predefined problems.


RESULTS
Fifty-four were evaluated after 6 months. The main criterion was defined for all three of the chosen themes at 76.9% in the PTE group and 42.4% in the WL group. Among the other positively evaluated criteria were: less corticotherapy, more occupational therapy, more demand for social aid, more physical activity, knowledge of the recognition of an RA attack and how to cope with it. On the other hand, knowledge of the treatments did not differ between the 2 groups nor did the RAPID scores, fatigue, stiffness, depression, compliance, number of consultations and hospitalisations. Patient satisfaction was excellent (between 85.3 and 93.9%).


CONCLUSION
This study is a good illustration of the position occupied and value of PTE in solving the problems specific to each RA case, the resulting high level of patient satisfaction and its independently complementary aspects relative to the purely medical treatment of RA. Customized PTE could better respond to specific patients problems in RA.

Greenwich, CT: JAI Press.], two studies tested whether a management style depicting situational uncertainty moderates the relationship between abusive supervision and workplace deviance. Study 1, using survey data from 379 subordinates of various industries, found that the positive relationship between abusive supervision and organizational deviance was stronger when authoritarian management style was low (high situational uncertainty) rather than high (low situational uncertainty). No significant interaction effect was found on interpersonal deviance. Study 2, using survey data from 1477 subordinates of various industries, found that the positive relationship between abusive supervision and supervisor-directed and organizational deviance was stronger when employees’ perceptions of their organization’s management style reflected high rather than low situational uncertainty. 2008 Elsevier Inc.

Classroom goal structures for educational math game application

This field study investigated the application of cooperative, competitive, and individualistic goal structures in classroom use of educational math games and its impact on students’ math performance and math learning attitudes. 124 5-grade students were recruited and randomly assigned to a Teams-Games-Tournament cooperative, interpersonal competitive, or individualistic gaming condition. A state-standards-based math exam and an inventory on attitudes toward mathematics were used in pretest and posttest. Students’ gender, socio economic status, and prior math ability were examined as the moderating variables. Results indicated that gaming in cooperative goal structure was most effective in promoting positive math attitudes while classroom goal structure for gaming had no significant impact on students’ math test performance. It was also found that students of different socio-economic statuses were influenced differently by the gaming conditions.
