On the Importance of Venue-Dependent Features for Learning to Rank Contextual Suggestions

Suggesting venues to a user in a given geographic context is an emerging task that is currently attracting a lot of attention. Existing studies in the literature consist of approaches that rank candidate venues based on different features of the venues and the user, which either focus on modeling the preferences of the user or the quality of the venue. However, while providing insightful results and conclusions, none of these studies have explored the relative effectiveness of these different features. In this paper, we explore a variety of user-dependent and venue-dependent features and apply state-of-the-art learning to rank approaches to the problem of contextual suggestion in order to find what makes a venue relevant for a given context. Using the test collection of the TREC 2013 Contextual Suggestion track, we perform a number of experiments to evaluate our approach. Our results suggest that a learning to rank technique can significantly outperform a Language Modelling baseline that models the positive and negative preferences of the user. Moreover, despite the fact that the contextual suggestion task is a personalisation task (i.e. providing the user with personalised suggestions of venues), we surprisingly find that user-dependent features are less effective than venue-dependent features for estimating the relevance of a suggestion.
Definition of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage as an outcome event in clinical trials and observational studies: proposal of a multidisciplinary research group.

BACKGROUND AND PURPOSE
In clinical trials and observational studies there is considerable inconsistency in the use of definitions to describe delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage. A major cause for this inconsistency is the combining of radiographic evidence of vasospasm with clinical features of cerebral ischemia, although multiple factors may contribute to DCI. The second issue is the variability and overlap of terms used to describe each phenomenon. This makes comparisons among studies difficult.


METHODS
An international ad hoc panel of experts involved in subarachnoid hemorrhage research developed and proposed a definition of DCI to be used as an outcome measure in clinical trials and observational studies. We used a consensus-building approach.


RESULTS
It is proposed that in observational studies and clinical trials aiming to investigate strategies to prevent DCI, the 2 main outcome measures should be: (1) cerebral infarction identified on CT or MRI or proven at autopsy, after exclusion of procedure-related infarctions; and (2) functional outcome. Secondary outcome measure should be clinical deterioration caused by DCI, after exclusion of other potential causes of clinical deterioration. Vasospasm on angiography or transcranial Doppler can also be used as an outcome measure to investigate proof of concept but should be interpreted in conjunction with DCI or functional outcome.


CONCLUSIONS
The proposed measures reflect the most relevant morphological and clinical features of DCI without regard to pathogenesis to be used as an outcome measure in clinical trials and observational studies.
Sesame Utilization in China: New Archaeobotanical Evidence from Xinjiang

Sesame Utilization in China: New Archaeobotanical Evidence from Xinjiang. A cache of sesame (Sesamum indicum L.) seeds, discovered in the Thousand Buddha Grottoes at Boziklik, Turpan, China, dating to ca. 700 years before present (BP), is hard evidence of their use in China since that time. Morphological and anatomical features suggest a white sesame cultivar. The sizeable quantity unearthed implies that sesame was a valued commodity that could provision the monks and enrich the diet of ancient inhabitants as an oil source. 芝麻在中国的利用:来自新疆的植物考古学证据.中国吐鲁番地区伯孜克里克千佛洞发现了一批距今约700年前的芝麻种子。这是中国古代栽培和利用芝麻的确凿证据。形态学和解剖学特征则鉴定其为白色类型芝麻。此次芝麻种子大量发现于佛寺内,说明其应该是僧侣们的油料来源,甚至可能在丰富当地先民的饮食结构方面扮演了重要角色。

Business model design : conceptualizing networked value co-creation

Purpose: A common thread in the modern marketing theories, such as service-dominant logic (Vargo and Lusch, 2004) and viable systems approach VSA (Golinelli et al., 2002), is the notion value co-creation: the locus of value creation is n o longer perceived to reside within firm boundaries but value is considered to be co-created between various actors within the networked market. The evolution of value creation, from value cr ation by the manufacturing firm to value cocreation in a network, necessitates a corresponding change in the concepts used to depict value creation. The present research investigates busines s models as a broader conceptualization of value co-creation that captures this change. Design/methodology/approach : The topic is approached by a combination of liter atu e review and interactive research (Gummesson, 2002a), including interactions with managers from 12 international companies. Findings: Business models are defined as configurations of twelve interrelated elements, covering market, offering, operational, and management viewp oints. The effectiveness of a business model in value co-creation is defined by the internal config urational fit between all business model elements and the external configurational fit between provid er’s and customers’ business models. Practical implications: A firm can radically improve the value co-creatio n by designing business models that have high degree of internal and extern al configurational fit. Originality/value : For a scholarly audience the article contributes to the discussion on value cocreation by providing a conceptualization of the bu siness model construct depicting the value cocreation in a network. For a practitioner audience it offers ideas for improving business performance through conscious business model develo pm nt.
First aid skill retention of first responders within the workplace

BACKGROUND
Recent literature states that many necessary skills of CPR and first aid are forgotten shortly after certification. The purpose of this study was to determine the skill and knowledge decay in first aid in those who are paid to respond to emergency situations within a workplace.


METHODS
Using a choking victim scenario, the sequence and accuracy of events were observed and recorded in 257 participants paid to act as first responders in large industrial or service industry settings. A multiple choice exam was also written to determine knowledge retention.


RESULTS
First aid knowledge was higher in those who were trained at a higher level, and did not significantly decline over time. Those who had renewed their certificate one or more times performed better than those who had learned the information only once. During the choking scenario many skills were performed poorly, regardless of days since last training, such as hand placement and abdominal thrusts. Compressions following the victim becoming unconscious also showed classic signs of skill deterioration after 30 days.


CONCLUSIONS
As many skills deteriorate rapidly over the course of the first 90 days, changing frequency of certification is not necessarily the most obvious choice to increase retention of skill and knowledge. Alternatively, methods of regularly "refreshing" a skill should be explored that could be delivered at a high frequency - such as every 90 days.
The Relationship Between Ethical Dilemma Discussion and Moral Development

The present investigation examines the relationship between ethical dilemma discussion and moral development of ninety-six second-year students taking a required communications course at a large northeastern school of pharmacy. An additional objective was to assess the efficacy of moral reasoning skills by testing the relationship between pharmacy students’ moral development and their perceptions regarding the difficulty of resolving ethical problems commonly found in pharmacy practice. Moral development has been demonstrated to be of consequence to professional behaviors such as clinical decision-making in health professionals. Rest’s Defining Issues Test (DIT) was used as a surrogate measure of a student’s moral reasoning. One hundred and nine students were administered the DIT at the beginning of the semester in which they took a required communications course, and again at the end of the semester. Of these, ninety-six protocols were deemed usable. A paired t-test revealed that students scored significantly higher on the post-test than on the pre-test. In addition, those students at higher levels of moral reasoning perceived as significantly less problematic common ethical dilemmas faced by practicing pharmacists. The study concludes that moral reasoning skills are both teachable and measurable, and that ethical dilemma case discussions may enhance moral development.

Availability Analysis Of A Bleaching System and Bread Manufacturing Plant Using Matlab

Upasana, Research scholar, Y.M.C.A. University of Science and Technology, Faridabad, INDIA Neetu Gupta, Assistant Professor , Mathematics, Y.M.C.A. University of Science and Technology, Faridabad, INDIA Yogesh Kumar Goyal, Associate Professor Mathematics, Aggarwal P.G. College, Ballabhgarh, Faridabad, INDIA Abstract In the manuscript, we calculate transient state availability of a bleaching system using MATLAB. The same system, we discuss applying matrix method [1]. The matrix method involves matrix multiplication. To make the method more friendly and practical we use MATLAB for matrix multiplication which is essentially involved in matrix method. The results of the two methods match completely. Dr Jai Singh et. al. [2] applies c++ to calculate availability of a complex system bread manufacturing plant which involves twenty four differential difference equations. For repeated multiplication of matrices in this method we use MATLAB. We observe that MATLAB gives more accuracy than multiplication by c++, as higher order multiple multiplication in MATLAB is more practical in comparison to c++.
Alveolar pressure monitoring: an evaluation in a lung model and in patients with acute lung injury

 Objectives. We evaluated an algorithm for continuous on-line monitoring of alveolar pressure over time in a lung model with lower and upper inflection points and variable resistance ratios and in patients with acute lung injury. The algorithm is based on "static" pressure/volume curves obtained from tracheal pressure measurements under dynamic conditions. Design and setting. Experimental and clinical evaluation of algorithm in a university hospital laboratory and intensive care unit. Patients. Ten patients undergoing postoperative respiratory therapy (feasibility of tracheal measurement) and ten patients with acute lung injury undergoing ventilator treatment (evaluation of algorithm). Measurements and results. Direct tracheal pressure measurements with a catheter inserted through the endotracheal tube. Comparison of measured alveolar and the dynostatic alveolar pressure vs. time in a lung model with changes in five ventilatory parameters. Examples of clinical monitoring are reported. In the model there was excellent agreement between alveolar pressures obtained by the algorithm, the dynostatic alveolar pressure, and measured alveolar pressure at all ventilator settings. For inspiratory/expiratory resistance ratios between 1:2.1–2.1:1, the dynostatic alveolar pressure was within ±1.5 cm H2O of measured alveolar pressure. In patients the technique for direct tracheal pressure measurement using a catheter inserted through the endotracheal tube functioned satisfactorily with intermittent air flushes for cleansing. Conclusions. Using a thin tracheal pressure catheter inserted through the endotracheal tube alveolar pressure allows continuous bedside monitoring with ease and precision using the dynostatic algorithm. The method is unaffected by tube and connector geometry or by secretions.
The Spaso technique: a prospective study of 34 dislocations.

BACKGROUND
The Spaso technique has been recently described as a new, simple, and effective manoeuvre for reducing anterior shoulder dislocation. However, there is a lack of series in the English literature. The aim of the study was to evaluate the results obtained with the introduction of this technique in an emergency department.


METHODS
An observational prospective study at the Hospital Clínic of Barcelona Orthopaedic Emergency Department was done from January 2007 to May 2007. In this period, the Spaso technique was applied in 36 anterior shoulder dislocations. Two of the patients were excluded due to a presentation later than 24 hours after the dislocation, leaving a total of 34 dislocations in 33 patients. They occurred in 22 male and 12 female shoulders. The patients' ages ranged from 21 to 80 years (average, 51 years). The success of the attempt, complications, and other data were collected.


RESULTS
The Spaso technique was successful in 23 (67.6%) of the 34 anterior shoulder dislocations. If just those patients with previous shoulder dislocations were taken into account, the success rate increased to 83%. No complications were observed.


CONCLUSION
Based on the results of the present study, we consider the Spaso technique as a safe and effective manoeuvre for the reduction of anterior shoulder dislocations, with an acceptable success rate similar to the classical techniques previously described.
Examining injury risk and pain perception in runners using minimalist footwear.

BACKGROUND
This study examines the effect of progressive increases in footwear minimalism on injury incidence and pain perception in recreational runners.


METHODS
One hundred and three runners with neutral or mild pronation were randomly assigned a neutral (Nike Pegasus 28), partial minimalist (Nike Free 3.0 V2) or full minimalist shoe (Vibram 5-Finger Bikila). Runners underwent baseline testing to record training and injury history, as well as selected anthropometric measurements, before starting a 12-week training programme in preparation for a 10 km event. Outcome measures included number of injury events, Foot and Ankle Disability (FADI) scores and visual analogue scale pain rating scales for regional and overall pain with running.


RESULTS
99 runners were included in final analysis with 23 injuries reported; the neutral shoe reporting the fewest injuries (4) and the partial minimalist shoe (12) the most. The partial minimalist shoe reported a significantly higher rate of injury incidence throughout the 12-week period. Runners in the full minimalist group reported greater shin and calf pain.


CONCLUSIONS
Running in minimalist footwear appears to increase the likelihood of experiencing an injury, with full minimalist designs specifically increasing pain at the shin and calf. Clinicians should exercise caution when recommending minimalist footwear to runners otherwise new to this footwear category who are preparing for a 10 km event.
Economic Evaluation of the Randomized Aldactone Evaluation Study (RALES): Treatment of Patients with Severe Heart Failure

Purpose: To use data from the Randomized Aldactone Evaluation Study (RALES) to compare clinical outcomes and costs as part of the assessment of the economic implications of spironolactone treatment of advanced heart failure. Methods: RALES was a randomized, double-blinded, placebo-controlled trial that enrolled participants who had severe heart failure and a left ventricular ejection fraction of no more than 35% and who were receiving standard therapy, including an angiotensin-converting enzyme inhibitor, a loop diuretic, and, in some cases, digoxin. We used a decision analytic model that incorporated data from participants in RALES as well as cost data from five countries that participated in the study. Costs were calculated for nonfatal hospitalizations, ambulatory care, spironolactone therapy, and death. The primary health outcome was quality-adjusted life-years saved (QALYS). Outcomes were evaluated for the first 35 months of observation in RALES. Results: Spironolactone therapy during the first 35 months of follow-up in RALES increased quality-adjusted survival time (0.13 QALYS, 95% CI, 0.07 to 0.18) without increasing costs ($713 savings, 95% CI, $2123 savings to $783 in costs). Spironolactone therapy either dominated placebo or had a ratio of cost per QALYS that was unlikely to exceed $20,300. These results were robust in both one-way and multiway sensitivity analyses. Conclusions: Even after implementation of current clinical guidelines, addition of spironolactone therapy provides an opportunity to further reduce the large clinical and economic burden of patients with heart failure.
Identification of Cryptosporidium subtype isolates from HIV-seropositive patients in Equatorial Guinea.

BACKGROUND
Cryptosporidium spp. are enteric parasites that infect humans and animals. In immunocompromised patients infection can be fatal. This study was conducted to identify sub-populations of Cryptosporidium hominis and C. parvum isolates from HIV-seropositive patients in Equatorial Guinea.


METHODS
In a previous study conducted in Equatorial Guinea, faecal samples from 171 HIV patients with gastrointestinal symptoms were analyzed. Of these, 13 and 17 were positive for C. hominis and C. parvum, respectively. The isolates were characterized using gp60 gene analysis.


RESULTS
The gp60 gene could only be detected in 57% (17/30) of cases (10 C. parvum and 7 C. hominis). Three C. hominis (Ia, Ib and Id) and two C. parvum (IIc and IIe) subtype families were detected, including several subtypes.


CONCLUSIONS
The study identified a high diversity of Cryptosporidium subtypes, suggesting that anthroponotic transmission plays an important role in the epidemiology of Cryptosporidium spp. in HIV-seropositive patients in Equatorial Guinea.

Multi-view object class detection with a 3D geometric model

This paper presents a new approach for multi-view object class detection. Appearance and geometry are treated as separate learning tasks with different training data. Our approach uses a part model which discriminatively learns the object appearance with spatial pyramids from a database of real images, and encodes the 3D geometry of the object class with a generative representation built from a database of synthetic models. The geometric information is linked to the 2D training data and allows to perform an approximate 3D pose estimation for generic object classes. The pose estimation provides an efficient method to evaluate the likelihood of groups of 2D part detections with respect to a full 3D geometry model in order to disambiguate and prune 2D detections and to handle occlusions. In contrast to other methods, neither tedious manual part annotation of training images nor explicit appearance matching between synthetic and real training data is required, which results in high geometric fidelity and in increased flexibility. On the 3D Object Category datasets CAR and BICYCLE [15], the current state-of-the-art benchmark for 3D object detection, our approach outperforms previously published results for viewpoint estimation.
Effectiveness of a specific care plan in patients with Alzheimer’s disease: cluster randomised trial (PLASA study)

OBJECTIVE
To test the effectiveness of a comprehensive specific care plan in decreasing the rate of functional decline in patients with mild to moderate Alzheimer's disease compared with usual care in memory clinics.


DESIGN
Cluster randomised trial.


SETTING
50 memory clinics in France.


PARTICIPANTS
Patients with Alzheimer's disease (mini-mental state examination score 12-26). 1131 patients were included: 574 from 26 clinics in the intervention group, and 557 from 24 clinics in the usual care (control) group. Memory clinics were the unit of randomisation.


INTERVENTION
The intervention included a comprehensive standardised twice yearly consultation for patients and their caregivers, with standardised guidelines for the management of problems identified during the assessment.


MAIN OUTCOME MEASURES
The primary outcome measure was change on the Alzheimer's Disease Cooperative Study-activities of daily living scale assessed at 12 and 24 months. Secondary outcome measures were the rate of admission to institutional care and mortality.


RESULTS
At two years the assessment was completed by 58.4% (n=335) of patients in the intervention group and 61.6% (n=343) in the control group. The rate of functional decline at two years did not differ between the groups. The annual rate of change on the Alzheimer's Disease Cooperative Study-activities of daily living was estimated at -5.73 (95% confidence interval -6.89 to -4.57) in the intervention group and -5.96 (-7.05 to -4.86) in the control group (P=0.78).


CONCLUSION
A comprehensive specific care plan in memory clinics had no additional positive effect on functional decline in patients with mild to moderate Alzheimer's disease. Future research should aim to determine the effects of more direct involvement of general practitioners.

Awake vs. asleep placement of spinal cord stimulators: a cohort analysis of complications associated with placement.

INTRODUCTION
Patients will typically undergo awake surgery for permanent implantation of spinal cord stimulation (SCS) in an attempt to optimize electrode placement using patient feedback about the distribution of stimulation-induced paresthesia. The present study compared efficacy of first-time electrode placement under awake conditions with that of neurophysiologically guided placement under general anesthesia.


METHODS
A retrospective review was performed of 387 SCS surgeries among 259 patients which included 167 new stimulator implantation to determine whether first time awake surgery for placement of spinal cord stimulators is preferable to non-awake placement.


RESULTS
The incidence of device failure for patients implanted using neurophysiologically guided placement under general anesthesia was one-half that for patients implanted awake (14.94% vs. 29.7%).


CONCLUSION
Non-awake surgery is associated with fewer failure rates and therefore fewer re-operations, making it a viable alternative. Any benefits of awake implantation should carefully be considered in the future.
