Brief alcohol intervention for college drinkers: how brief is?

OBJECTIVE
Brief interventions for college student drinkers have been shown to be effective in reducing the amount of alcohol consumed as well as the number of alcohol-related problems. However, the duration of brief interventions varies substantially across studies.


METHOD
In the present study 114 undergraduate students who drank alcohol heavily were randomly assigned to a 10-minute brief intervention, a 50-minute brief intervention, or assessment-only control. The content of the active interventions was based on the same concept, and both interventions incorporated motivational interviewing components. Participants were assessed at baseline and 4-week post intervention on quantity of alcohol use, alcohol-related problems, and protective behavioral strategies.


RESULTS
As hypothesized, there was a significant difference between participants in the 10-minute intervention and control condition regarding their alcohol consumption at 4-week follow up. However, there was no significant difference between the 50-minute intervention and the control condition on alcohol consumption. There were also no significant differences between active intervention conditions, and neither intervention showed advantages for reducing problems or increasing protective behaviors relative to the control condition.


CONCLUSIONS
Results suggest a very brief intervention can impact short-term alcohol use outcomes, with potentially no advantage of longer interventions for this population.
Thyroid cancer in thyroglossal duct cysts requires a specific approach due to its unpredictable extension.

CONTEXT
Differentiated thyroid cancer (DTC) in thyroglossal duct cysts is uncommon. The requirement of total thyroidectomy and lymph node dissection is still controversial.


SETTING
The study was performed in a referral thyroid cancer center at an academic hospital.


PATIENTS
We conducted a single center retrospective study of a consecutive series of 26 patients with DTC in thyroglossal duct cyst, all having undergone cyst resection and total thyroidectomy.


MAIN OUTCOME MEASURES
Diagnostic modalities, surgical treatment, histopathological features, and clinical outcome were included in the study.


RESULTS
Thyroglossal duct cyst cancer histotype was papillary in 23 of 26 patients (88.5%) and follicular-Hurthle in 3 of 26 cases (11.5%). A concomitant papillary DTC in the thyroid gland was found in 16 of 26 cases (61.5%), and it was multifocal in 8 of 16 cases (50%). At presentation, the patients with cancer in both the thyroglossal duct cyst and the thyroid were older than the patients who only had cancer in the thyroglossal duct cyst (44.9 ± 7.6 vs 32.0 ± 12.7; P = .006). Lymph node dissection, performed in 17 of 26 patients (65.4%), indicated that the central compartment was involved in 6 patients (35.3%, all having cancer also in the thyroid), the laterocervical compartments in 10 patients (58.8%), and the submental in 4 (23.5%). Six patients (23.1%) had persistent disease at 6-year median follow-up.


CONCLUSIONS
DTC in thyroglossal duct cysts occurs at a younger age and with more aggressive features at presentation. Concomitant cancer in the thyroid and lymph node metastases is present in most cases. Lymph node compartment involvement is different from that of cancers in the thyroid gland. Therefore, surgical treatment should include both thyroglossal duct cyst resection and total thyroidectomy, with individualized surgical nodal dissection. Subsequent management should follow current DTC guidelines.
Combining chemical and biological endpoints, a major challenge for twenty-first century's environmental specimen banks.

Environmental specimen banks (ESBs) are not a new phenomenon, but in the last decades, the steep rate in the establishment of new ESBs is a sign to address new research approaches for scientists. In this way, environmental biobanking is becoming a well-organized and effective vehicle to collect samples of high quality making them available for future researchers. The endpoints promoted in the ESBs are mainly based on chemical approaches, but the necessity to add biological endpoint is fundamental (e.g., assessment of the environmental health status). Moreover, advances and development of high sensitive, high-throughput techniques along with ecotoxicological approaches based on biomarkers are stimulating a new demand for stored specimens and associated data. Like in chemically targeted environmental specimen banking, the banked samples for the assessment of biological effects also require guidance informed by knowledge of their practices and challenges, along with policies for the correct advancement of research goals and appropriate and effective biobank governance.
Plasma zinc concentration responds to short-term zinc supplementation, but not zinc fortification, in young children in Senegal1,2.

BACKGROUND
Simple, low-cost methods are needed to evaluate the effect of zinc-fortification programs. Plasma zinc concentration is a useful biomarker of zinc intake from supplementation, but responses to zinc fortification are inconsistent.


OBJECTIVE
The objective was to compare the change in plasma zinc concentrations in young children who received zinc from either a liquid supplement or a zinc-fortified complementary food.


DESIGN
A double-blind intervention trial was conducted in 137 young Senegalese children aged 9-17 mo who were randomly assigned to receive one of the following treatments for 15 d: 1) 30 g dry weight of an iron-fortified cereal porridge and a liquid multivitamin supplement without zinc (control group), 2) the same porridge and multivitamin supplement with 6 mg Zn added to the supplement dose (ZnSuppl group), or 3) the same porridge with added zinc to provide 6 mg Zn per 25 g dry weight of porridge and multivitamin without zinc (ZnFort group).


RESULTS
Mean (±SD) plasma zinc concentration (μg/dL) increased by 4.7 ± 1.6 (P = 0.004) in the ZnSuppl group, which was significantly greater (P = 0.009) than the mean change in the control group (-1.0 ± 1.6; P = 0.51) and in the ZnFort group (-1.8 ± 1.7; P = 0.29). The latter 2 groups did not differ from each other (P = 0.99).


CONCLUSIONS
Plasma zinc concentration increased in children who received daily zinc supplementation for 15 d but not in those who received a zinc-fortified complementary food containing a similar amount of zinc. Additional longer-term studies are needed to assess the effect of zinc-fortification programs on zinc-related functional outcomes and the usefulness of plasma zinc as a biomarker of program effect. This trial was registered at www.clinicaltrials.gov as study NCT0094398.

Contention-Aware Lock Scheduling for Transactional Databases

Lock managers are among the most studied components in concurrency control and transactional systems. However, one question seems to have been generally overlooked: “When there are multiple lock requests on the same object, which one(s) should be granted first?” Nearly all existing systems rely on a FIFO (first in, first out) strategy to decide which transaction(s) to grant the lock to. In this paper, however, we show that the lock scheduling choices have significant ramifications on the overall performance of a transactional system. Despite the large body of research on job scheduling outside the database context, lock scheduling presents subtle but challenging requirements that render existing results on scheduling inapt for a transactional database. By carefully studying this problem, we present the concept of contention-aware scheduling, show the hardness of the problem, and propose novel lock scheduling algorithms (LDSF and bLDSF), which guarantee a constant factor approximation of the best scheduling. We conduct extensive experiments using a popular database on both TPC-C and a microbenchmark. Compared to FIFO— the default scheduler in most database systems—our bLDSF algorithm yields up to 300x speedup in overall transaction latency. Alternatively, our LDSF algorithm, which is simpler and achieves comparable performance to bLDSF, has already been adopted by open-source community, and was chosen as the default scheduling strategy in MySQL 8.0.3+.

simNet: Stepwise Image-Topic Merging Network for Generating Detailed and Comprehensive Image Captions

The encode-decoder framework has shown recent success in image captioning. Visual attention, which is good at detailedness, and semantic attention, which is good at comprehensiveness, have been separately proposed to ground the caption on the image. In this paper, we propose the Stepwise Image-Topic Merging Network (simNet) that makes use of the two kinds of attention at the same time. At each time step when generating the caption, the decoder adaptively merges the attentive information in the extracted topics and the image according to the generated context, so that the visual information and the semantic information can be effectively combined. The proposed approach is evaluated on two benchmark datasets and reaches the state-of-the-art performances.1
Liraglutide reverses pronounced insulin-associated weight gain, improves glycaemic control and decreases insulin dose in patients with type 2 diabetes: a 26 week, randomised clinical trial (ELEGANT)

The best treatment strategy for a patient with type 2 diabetes who shows pronounced weight gain after the introduction of insulin treatment is unclear. We determined whether addition of a glucagon-like peptide-1 (GLP-1) analogue could reverse pronounced insulin-associated weight gain while maintaining glycaemic control, and compared this with the most practised strategy, continuation and intensification of standard insulin therapy. In a 26-week, randomised controlled trial (ELEGANT), conducted in the outpatient departments of one academic and one large non-academic teaching hospital in the Netherlands, adult patients with type 2 diabetes with ≥4% weight gain during short-term (≤16 months) insulin therapy received either open-label addition of liraglutide 1.8 mg/day (n = 26) or continued standard therapy (n = 24). A computer-generated random number list was used to allocate treatments. Participants were evaluated every 4–6 weeks for weight, glycaemic control and adverse events. The primary endpoint was between-group weight difference after 26 weeks of treatment (intention to treat). Of 50 randomised patients (mean age 58 years, BMI 33 kg/m2, HbA1c 7.4% [57 mmol/mol]), 47 (94%) completed the study; all patients were analysed. Body weight decreased by 4.5 kg with liraglutide and increased by 0.9 kg with standard therapy (mean difference −5.2 kg [95% CI −6.7, −3.6 kg]; p < 0.001). The respective changes in HbA1c were −0.77% (−8.4 mmol/mol) and +0.01% (+0.1 mmol/mol) (difference −0.74% [−8.1 mmol/mol]) ([95% CI −1.08%, −0.41%] [−11.8, −4.5 mmol/mol]; p < 0.001); respective changes in insulin dose were −29 U/day and +5 U/day (difference −33 U/day [95% CI −41, −25 U/day]; p < 0.001). In five patients (19%), insulin could be completely discontinued. Liraglutide was well tolerated; no severe adverse events or severe hypoglycaemia occurred. In patients with pronounced insulin-associated weight gain, addition of liraglutide to their treatment regimen reverses weight, decreases insulin dose and improves glycaemic control, and hence seems a valuable therapeutic option compared with continuation of standard insulin treatment.

Conventionalisation of organic farming practices: from structural criteria towards an assessment based on organic principles. A review

Organic farming is widely perceived as being more environmentally friendly than conventional farming. As a form of sustainable agriculture, it receives substantial support from policy for its contribution to environmental protection as well as the provision of amenities such as biodiversity and cultural landscapes. Consumers are attracted to organic foods as they are produced without synthetic chemicals and comply with higher animal welfare standards. Although organic farming certainly has the potential to fulfil these expectations, studies have shown that some certified organic farms do not. Their practices comply with the regulations, but not with the principles of organic farming. This trend has been called ‘conventionalisation’ of organic farming. In this paper we review the studies that discuss the conventionalisation of organic farming, focusing on the farm level and on evidence from Europe. We argue that to strengthen organic farming’s transformative potential, the debate must move beyond its focus on the bifurcation between artisanal and conventionalised organic farms, so as to capture the full range of empirical heterogeneity. Our core argument is that to adequately understand the dynamics within organic farming and their potential impact on the ability of organic farming to fulfil the expectations of consumers and policy-makers, it is not sufficient to focus on structural changes. Instead, we need to assess whether or not the observed changes comply with the principles and values that are the fundament of organic farming.
An efficient omnidirectional vision system for soccer robots : From calibration to object detection

Robotic soccer is nowadays a popular research domain in the area of multi-robot systems. In the context of RoboCup, the Middle Size League is one of the most challenging. This paper presents an efficient omnidirectional vision system for real-time object detection, developed for the robotic soccer team of the University of Aveiro, CAMBADA. The vision system is used to find the ball and white lines, which are used for self-localization, as well as to find the presence of obstacles. Algorithms for detecting these objects and also for calibrating most of the parameters of the vision system are presented in this paper. We also propose an efficient approach for detecting arbitrary FIFA balls, which is an important topic of research in the Middle Size League. The experimental results that we present show the effectiveness of our algorithms, both in terms of accuracy and processing time, as well as the results that the team has been achieving: 1st place in RoboCup 2008, 3rd place in 2009 and 1st place in the mandatory technical challenge in RoboCup 2009, where the robots have to play with an arbitrary standard FIFA ball. 2010 Elsevier Ltd.

Upper airway collapsibility, dilator muscle activation and resistance in sleep apnoea.

The calibre of the upper airway is thought to be dependant upon its passive anatomy/collapsibility and the activation of pharyngeal dilator muscles. During awake periods, the more collapsible upper airway in obstructive sleep apnoea (OSA) increases the dilator muscle activity through a negative-pressure reflex. A direct correlation between the critical closing pressure (P(crit)), as a measure of anatomy/collapsability and electromyogram (EMG) activity of genioglossus EMG (GG-EMG) and tensor palatini EMG (TP-EMG), was hypothesised. The relationship between these indices and pharyngeal resistance (R(phar)) was also examined. The study involved eight males with a mean age of 48 (interquartile range 46-52) yrs with OSA, and an apnoea/hypopnoea index of 75 (65-101).hr(-1) on two nights breathing normally and on nasal continuous positive airway pressure (nCPAP). The P(crit )was measured during nonrapid eye movement sleep on nCPAP using brief, incremental reductions in mask pressure. GG-EMG and TP-EMG were measured breath-by-breath, awake, during sleep onset and on nCPAP. R(phar) was measured using airway pressures and flow. Wakeful GG-EMG, early sleep TP-EMG and the sleep decrement in TP-EMG were directly related to P(crit). Muscle activation was negatively correlated with R(phar) for TP-EMG awake and GG-EMG early in sleep. In conclusion these results confirm that dilator muscle activation is directly related to airway narrowing and reduces resistance across patients with obstructive sleep apnoea.
Semantic web services: Standards, applications, challenges and solutions

To share Knowledge coming from disparate and heterogeneous environments, we propose the use of semantic Web services to provide a common Knowledge format and meaning. Semantic Web services would require careful usage of combined technologies. On one hand, XML Web services technology because of their system agnostic nature and the ease of integration and, on the other hand, the semantic Web can define and link Web data in a way that it can be understood and used by software agents. This mixed technology may be a solution to functional interoperability, technical interoperabilty, semantic interoperability and flexible development in heterogeneous environments using the Internet as the main infrastructure. In this paper a survey of semantic Web services is realized to show that they ensure interoperability. Four aspects of Web services are presented: (1) Standards of XML Web services (eXtended Markup Language Web services) and their limits, (2) Languages and Tools of Semantic Annotation, (3) Web Services Composition, and (4) Performance Evaluation. Observations on some new challenges brought by semantic Web services are cited. Furthermore, a comparative study is presented, over the Internet and Intranet, based on numerical results using a discrete event between semantic Web services and distributed middleware, e.g. CORBA (Common Object Request Broker Architecture) and JAVA RMI (JAVA Remote Method Invocation). & 2014 Elsevier Ltd.

From Social to Sale: The Effects of Firm-Generated Content in Social Media on Customer Behavior

Given the unprecedented reach of social media, firms are increasingly relying on it as a channel for marketing communication. The objective of this study is to examine the effect of firm-generated content (FGC) in social media on three key customer metrics: spending, cross-buying, and customer profitability. The authors further investigate the synergistic effects of FGC with television advertising and e-mail communication. To accomplish their objectives, the authors assemble a novel data set comprising customers’ social media participation data, transaction data, and attitudinal data obtained through surveys. The results indicate that after the authors account for the effects of television advertising and e-mail marketing, FGC has a positive and significant effect on customers’ behavior. The authors show that FGC works synergistically with both television advertising and e-mail marketing and also find that the effect of FGC is greater for more experienced, tech-savvy, and social media–prone customers. They propose and examine the effect of three characteristics of FGC: valence, receptivity, and customer susceptibility. The authors find that whereas all three components of FGC have a positive impact, the effect of FGC receptivity is the largest. The study offers critical managerial insights regarding how to leverage social media for better returns.
Proximal tibial fractures: early experience using polyaxial locking-plate technology

Between 2004 and 2009, 60 patients with proximal tibial fractures were included in this prospective study. All fractures were treated with the polyaxial locked-plate fixation system (DePuy, Warsaw, IN, USA). Clinical and radiographic data, including fracture pattern, changes in alignment, local and systemic complications, hardware failure and fracture union were analysed. The mean follow-up was 14 (12–36) months. According to the Orthopaedic Trauma Association (OTA) classification, there were five 41-A, 28 41-B and 27 41-C fractures. Fractures were treated percutaneously in 30% of cases. Double-plating was used in 11 cases. All but three fractures progressed to union at a mean of 3.2 (2.5–5) months. There was no evidence of varus collapse as a result of polyaxial screw failure. No plate fractured, and no screw cut out was noted. There was one case of lateral joint collapse (>10°) in a patient with open bicondylar plateau fracture. The mean Knee Society Score at the time of final follow-up was 91 points, and the mean functional score was 89 points. The polyaxial locking-plate system provided stable fixation of extra-articular and intra-articular proximal tibial fractures and good functional outcomes with a low complication rate.
Two-warehouse inventory models for deteriorating items with shortages under inflation

In this paper, the two-warehouse inventory problem for deteriorating items with constant demand rate and shortages under inflation is considered. In contrast to the traditional deterministic two-warehouse inventory model with shortages at the end of each replenishment cycle, an alternative model in which each cycle begins with shortages and ends without shortages is proposed here. The optimal solution not only exists but also is unique. Comparing these two two-warehouse inventory models, the study shows that the proposed model is less expensive to operate than the traditional one in the case of the inflation rate is greater than zero. Hence, under the consideration of inflationary effect, the proposed model is less expensive. Finally, some numerical examples for illustration are provided. 2003 Elsevier B.V. All rights reserved.
PLOS ONE: The Network of Global Corporate Control

The structure of the control network of transnational corporations affects global market competition and financial stability. So far, only small national samples were studied and there was no appropriate methodology to assess control globally. We present the first investigation of the architecture of the international ownership network, along with the computation of the control held by each global player. We find that transnational corporations form a giant bow-tie structure and that a large portion of control flows to a small tightly-knit core of financial institutions. This core can be seen as an economic “super-entity” that raises new important issues both for researchers and policy makers.
