Association of sport and recreational facilities with adult residents' participation in leisure time physical activities in Addis Ababa, Ethiopia
Venue: Sport in Society
Year: 2019

The Sport Policy of Ethiopia, declared in 1998, underlines the importance of developing public sport and recreational facilities to the community for enhancing mass participation. However, after 20 years of its implementation, residents in Addis Ababa still play ball games on derelict areas and complain about scarcity of physical activity resources. This study investigated the provision of resources and its association with participation level of adult residents in LTPA in Nefas Silk Lafto sub city, Addis Ababa. Adult residents (n 384) sport facility experts (n 32) and sport facility department heads (n 2) participated in the study. We used questionnaires, observations, interview and GIS measures for collecting data and analyzed them by descriptive methods, t test, ANOVA and multiple regression. Poor availability, low participation and positive association between facility provision and level of participation were indicated. The article argues that there is a gap in realizing policy objective, which has its roots in providing resources.
Information Technology and Firm Profitability: Mechanisms and Empirical Evidence
Venue: MIS Q.
Year: 2012

Do information technology investments improve firm profitability? If so, is this effect because such investments help improve sales, or is it because they help reduce overall operating expenses? How does the effect of IT on profitability compare with that of advertising and of research and development? These are important questions because investments in IT constitute a large part of firms' discretionary expenditures, and managers need to understand the likely impacts and mechanisms to justify and realize value from their IT and related resource allocation processes. The empirical evidence in this paper, derived using archival data from 1998 to 2003 for more than 400 global firms, suggests that IT has a positive impact on profitability. Importantly, the effect of IT investments on sales and profitability is higher than that of other discretionary investments, such as advertising and R&D. A significant portion of the impact of IT on firm profitability is accounted for by IT enabled revenue growth, but there is no evidence for the effect of IT on profitability through operating cost reduction. Taken together, these findings suggest that firms have had greater success in achieving higher profitability through IT enabled revenue growth than through IT enabled cost reduction. They also provide important implications for managers to make allocations among discretionary expenditures such as IT, advertising, and R&D. With regard to IT expenditures, the results imply that firms should accord higher priority to IT projects that have revenue growth potential over those that focus mainly on cost savings.
Patient access to medical records and healthcare outcomes: a systematic review
Venue: J. Am. Medical Informatics Assoc.
Year: 2014

We conducted a systematic review to determine the effect of providing patients access to their medical records (electronic or paper based) on healthcare quality, as defined by measures of safety, effectiveness, patient centeredness, timeliness, efficiency, and equity.  Articles indexed in PubMed from January 1970 to January 2012 were reviewed. Twenty seven English language controlled studies were included. Outcomes were categorized as measures of effectiveness (n=19) patient centeredness (n=16) and efficiency (n=2) no study addressed safety, timeliness, or equity.  Outcomes were equivocal with respect to several aspects of effectiveness and patient centeredness. Efficiency outcomes in terms of frequency of in person and telephone encounters were mixed. Access to health records appeared to enhance patients' perceptions of control and reduced or had no effect on patient anxiety.  Although few positive findings generally favored patient access, the literature is unclear on whether providing patients access to their medical records improves quality.
EXPERIMENTAL APPROACH FOR UNDERSTANDING THE DYNAMIC BEHAVIORS OF BENTONITE BUFFER PIPING EROSION
Year: 2019

In Japan, as in other countries, bentonite based buffer materials are expected to play roles in reducing stress from rock masses and mitigating nuclide migration in the geological disposal of high level radioactive waste. These roles are achieved by ensuring buffer density and thickness based on the swelling characteristics of clay. However, in practical construction, we should also consider bentonite buffer piping erosion, a phenomenon in which the buffer surface is destroyed by groundwater flowing between the buffer and rock. Such piping erosion may be a serious issue for maintaining an engineered barrier for radioactive waste in the geological system. In this study, the dynamic behaviors of piping erosion were experimentally investigated. In the experiments, 500 mm ph x 600 mm height compacted bentonite specimens were placed in a cylindrical acrylic cell and distilled water was continuously injected at a flow rate of 0.1 L/min from the bottom and the side of the cell. The amount of bentonite that flowed out of the cell was measured by turbidity of the suspended clay in the drainage water. In the results, while the bentonite specimen swelled between about 10 and 20 days and attached to the inside wall of the cell, a dominant flow channel (piping) was observed between the swelled bentonite specimen and the inside wall of the cell. In addition, the relationship between the accumulated amounts of injected water and eroded bentonite showed a constant slope on double logarithmic plots. Such behaviors indicate that the shear stress due to water flow locally exceeded the swelled bentonite's shear strength. Furthermore, the slopes were similar to those already reported from a test using a smaller size cell. These results suggest that piping erosion proceeds with a simple regularity and that piping erosion in actual scale bentonite buffers can be predicted using small scale data.

Exploring Male Multiple Orgasm in a Large Online Sample: Refining Our Understanding.
Venue: The journal of sexual medicine
Year: 2021

The scientific literature on multiple orgasm in males is small. There is little consensus on a definition, and significant controversy about whether multiple orgasm is a unitary experience.  This study has 2 goals: (i) describing the experience of male multiple orgasm; (ii) investigating whether there are different profiles of multiple orgasm in men.  Data from a culturally diverse online convenience sample of 122 men reporting multiple orgasm were collected. Data reduction analyses were conducted using principal components analysis (PCA) on 13 variables of interest derived from theory and the existing literature. A K means cluster analysis followed, from which a 4 cluster solution was retained.  While the range of reported orgasms varied from 2 to 30, the majority (79.5% N 97) of participants experienced between 2 and 4 orgasms separated by a specific time interval during which further stimulation was required to achieve another orgasm. Most participants reported maintaining their erections throughout and ejaculating with every orgasm. Age was not a significant correlate of the multiple orgasm experience which occurred more frequently in a dyadic context. Four different profiles of multiorgasmic men were described.  This study constitutes a rare attempt to collect systematic self report data concerning the experience of multiple orgasm in a relatively large sample. Limitations include the lack of validated measures, memory bias associated with self reported data and retrospective designs, the lack of a control group and of physiological measurement.  Our study suggests that multiple orgasm in men is not a unitary phenomenon and sets the stage for future self report and laboratory study.

Energetic ion induced desorption of hydrogen from porous silicon studied by on line elastic recoil detection analysis
Year: 2017

We report a detailed study on the concentration profiles and ion irradiation induced desorption of hydrogen from porous silicon (pSi) by on line elastic recoil detection analysis (ERDA) 100 MeV Ag ions have been employed to analyze the pSi samples prepared at different etching current densities. The observed blue shift in the photoluminescence of pSi with increase in etching current density is consistent with previous reports. Here we find that the concentration of hydrogen in near surface regions decreases with increase in etching current density. It is also observed that the concentration of hydrogen is greater in the near surface region and decreases rapidly as a function of depth in porous silicon. Further, the ion irradiation induced desorption of hydrogen from pSi has been characterized by the second order decay, indicating that the hydrogen desorbs in molecular form. The rate of desorption is found to be higher from the deeper layers when compared to that of near surface regions, possibly due to higher diffusivity of elemental hydrogen within the deeper layer. Strong electronic excitations produced by probing beam are expected to be responsible for the observed non thermal dissociation of Si H bonds and consequent desorption of hydrogen from the surface of pSi in molecular form. These results provide useful information to elucidate 1) the role of hydrogen in determining the optical properties of porous/nano crystalline silicon and 2) mechanisms that govern the non thermal dissociation of Si H bonds.
New opportunities for comparative male fertility research: Insights from a new data resource based on high quality birth registers
Year: 2019

Obtaining cross country comparative perspectives on male fertility has long been difficult, as male fertility is usually less well registered than female fertility. This paper presents analyses based on a new male fertility database providing data on more than 330 million live births. This new resource, made available in the Human Fertility Collection, allows for the first time a comparative perspective on male fertility in high income countries using high quality birth register data. Contrasting male and female fertility trends across 17 countries, we show that trends in disparities between male and female period fertility rates are driven to a large degree by the interplay of parental age and cohort size differences. For parental age differences at childbirth, we observe a tendency toward smaller disparities, except in Eastern Europe. This observation fits with expectations based on gender theories. However, variation across countries also seems to be driven by factors other than gender equality.

Calling the Cloud: Enabling Mobile Phones as Interfaces to Cloud Applications
Venue: Middleware
Year: 2009

Mobile phones are set to become the universal interface to online services and cloud computing applications. However, using them for this purpose today is limited to two configurations: applications either run on the phone or run on the server and are remotely accessed by the phone. These two options do not allow for a customized and flexible service interaction, limiting the possibilities for performance optimization as well. In this paper we present a middleware platform that can automatically distribute different layers of an application between the phone and the server, and optimize a variety of objective functions (latency, data transferred, cost, etc. Our approach builds on existing technology for distributed module management and does not require new infrastructures. In the paper we discuss how to model applications as a consumption graph, and how to process it with a number of novel algorithms to find the optimal distribution of the application modules. The application is then dynamically deployed on the phone in an efficient and transparent manner. We have tested and validated our approach with extensive experiments and with two different applications. The results indicate that the techniques we propose can significantly optimize the performance of cloud applications when used from mobile phones.
Variational Inference for Computational Imaging Inverse Problems
Venue: J. Mach. Learn. Res.
Year: 2020

Machine learning methods for computational imaging require uncertainty estimation to be reliable in real settings. While Bayesian models offer a computationally tractable way of recovering uncertainty, they need large data volumes to be trained, which in imaging applications implicates prohibitively expensive collections with specific imaging instruments. This paper introduces a novel framework to train variational inference for inverse problems exploiting in combination few experimentally collected data, domain expertise and existing image data sets. In such a way, Bayesian machine learning models can solve imaging inverse problems with minimal data collection efforts. Extensive simulated experiments show the advantages of the proposed framework. The approach is then applied to two real experimental optics settings: holographic image reconstruction and imaging through highly scattering media. In both settings, state of the art reconstructions are achieved with little collection of training data.
Critical Care Management of Cerebral Edema in Brain Tumors
Venue: Journal of intensive care medicine
Year: 2017

Cerebral edema associated with brain tumors is extremely common and can occur in both primary and metastatic tumors. The edema surrounding brain tumors results from leakage of plasma across the vessel wall into the parenchyma secondary to disruption of the blood brain barrier. The clinical signs of brain tumor edema depend on the location of the tumor as well as the extent of the edema, which often exceeds the mass effect induced by the tumor itself. Uncontrolled cerebral edema may result in increased intracranial pressure and acute herniation syndromes that can result in permanent neurological dysfunction and potentially fatal herniation. Treatment strategies for elevated intracranial pressure consist of general measures, medical interventions, and surgery. Alhough the definitive treatment for the edema may ultimately be surgical resection of the tumor, the impact of the critical care management cannot be underestimated and thus patients must be vigilantly monitored in the intensive care unit. In this review, we discuss the pathology, pathophysiology, and clinical features of patients presenting with cerebral edema. Imaging findings and treatment modalities used in the intensive care unit are also discussed.
Constructing Skill Trees for Reinforcement Learning Agents from Demonstration Trajectories
Venue: NIPS
Year: 2010

We introduce CST, an algorithm for constructing skill trees from demonstration trajectories in continuous reinforcement learning domains. CST uses a change point detection method to segment each trajectory into a skill chain by detecting a change of appropriate abstraction, or that a segment is too complex to model as a single skill. The skill chains from each trajectory are then merged to form a skill tree. We demonstrate that CST constructs an appropriate skill tree that can be further refined through learning in a challenging continuous domain, and that it can be used to segment demonstration trajectories on a mobile manipulator into chains of skills where each skill is assigned an appropriate abstraction.
On asymptotically optimal confidence regions and tests for high dimensional models
Year: 2014

We propose a general method for constructing confidence intervals and statistical tests for single or low dimensional components of a large parameter vector in a high dimensional model. It can be easily adjusted for multiplicity taking dependence among tests into account. For linear models, our method is essentially the same as in Zhang and Zhang [ (2014) 217 242] we analyze its asymptotic properties and establish its asymptotic optimality in terms of semiparametric efficiency. Our method naturally extends to generalized linear models with convex loss functions. We develop the corresponding theory which includes a careful analysis for Gaussian, sub Gaussian and bounded correlated designs.
"What is the Benefit of Adorning Him with Flowers and Greenery?" The Attitude of Rabbis in Germany and the Land of Israel in Modern Times to Laying Wreaths at Burial and Memorial Ceremonies
Year: 2017

Rabbinic literature in modern times includes a list of halachic debates on the integration of mourning and memorial customs, originating in general society, into the Jewish traditional burial ceremony. Examples include: transporting the deceased to the cemetery in horse drawn carriages; wearing black clothes or a black ribbon on the mourner's clothing; three volley salutes at military funerals; and standing while the siren is sounded on Holocaust and Heroism Remembrance Day and on the Memorial Day for Fallen Soldiers and Victims of Terrorism. The poskim (adjudicators) dealt, among other things, with the halachic attitude toward laying wreaths on coffins, graves, and memorials. Initial doubts regarding this custom began to emerge in Jewish communities in nineteenth century Europe. The issue continued to trouble halachic authorities during the twentieth century, particularly after the State of Israel was founded, and documentation of such deliberations may be found in the literature and on the internet up to present times. Laying wreaths as part of the traditional funeral ceremony has aroused bitter feelings among the ultra Orthodox public in Israel and elsewhere, as is evident particularly from the Orthodox press and the responsa literature. Then again, attempts to prevent those of the secular public interested in honoring their dear ones in this way have also been a cause of objection, generating a sense of religious coercion. One of the later manifestations of hard feelings among the general Israeli public is evident in the words of author Amos Oz and his daughter, historian Fania Oz Salzberger, prominent figures in Israeli culture. In their book "Jews and Words," they take exception to the fact that the ultraOrthodox consider the laying of wreaths on the grave a foreign custom, considering that for many years this segment of society had embraced the customs of their historical surroundings:
Efficacy and safety of adjunctive cariprazine in inadequate responders to antidepressants: a randomized, double blind, placebo controlled study in adult patients with major depressive disorder.
Venue: The Journal of clinical psychiatry
Year: 2016

Cariprazine is an atypical antipsychotic currently under investigation as adjunctive therapy in patients with major depressive disorder (MDD) who have inadequate response to standard antidepressant therapy.  A randomized, double blind, placebo controlled, flexible dose study was conducted from December 2011 to December 2013 in adults who met DSM IV TR criteria for MDD and had an inadequate antidepressant response. Eligible patients were randomized to 8 week adjunctive treatment with placebo (n 269) cariprazine 1 2 mg/d (n 274) or cariprazine 2 4.5 mg/d (n 276) The primary efficacy parameter was change from baseline to week 8 in Montgomery Asberg Depression Rating Scale (MADRS) total score; P values were adjusted for multiple comparisons. Safety assessments included adverse events, clinical laboratory tests, vital signs, electrocardiograms (ECGs) and suicidality.  Compared with placebo, reduction in MADRS total score at week 8 was significantly greater with adjunctive cariprazine 2 4.5 mg/d (least squares mean difference [LSMD] 2.2; adjusted P .0114) but not with cariprazine 1 2 mg/d (LSMD 0.9; adjusted P .2404) Significant LSMDs for MADRS total score change were detected at all earlier study visits (weeks 2, 4, 6) in the 2 to 4.5 mg/d group and at weeks 2 and 4 in the 1 to 2 mg/d group (all P values .05) Treatment emergent adverse events reported in 10% of patients in either cariprazine dosage group were akathisia (22.3% insomnia (13.6% and nausea (12.8% (all in 2 to 4.5 mg/d group) Mean changes in metabolic parameters, vital signs, and ECG parameters were generally similar between groups. No suicide related adverse events were reported.  These results show that adjunctive cariprazine 2 4.5 mg/d was effective and generally well tolerated in adults with MDD who had inadequate responses to standard antidepressants. Further clinical studies to confirm these results are warranted.
Progress and Prospects of Recurrent Glioma: A Recent Scientometric Analysis of the Web of Science in 2019
Year: 2020

Most patients with glioma experience recurrence and have a poor prognosis. Scientometric analysis is effective and widely used to summarize the most influential studies within a certain field. We present the first scientometric analysis of recurrent glioma.  We conducted a generalized search for articles on recurrent glioma in the Web of Science database and evaluated the top 100 most cited articles among 4651 articles.  The number of citations from the top 100 cited articles on recurrent glioma ranged from 149 to 1471; most of these articles were published in oncology specific journals (66) and were submitted by institutions in the United States (n 67) The top cited articles consisted of 98 articles and 2 literature reviews. Articles were classified into 4 major categories based on subject matter: 82 pertained to treatment, 6 pertained to genetic mechanisms, 7 pertained to diagnosis, and 5 pertained to prognosis. Treatment related articles were subdivided into the following 7 categories: targeted therapy (n 21) chemotherapy (n 20) immunotherapy (n 12) combination therapy (n 12) radiotherapy (n 9) surgical resection (n 6) a new therapy (physiotherapy) (n 1) and treatment summary (n 1)  The results of the analysis indicated that the core problem is the treatment of recurrent glioma. Although the number of citations on targeted therapy and combination therapy has increased in recent years, the proportion of randomized controlled trials, basic medical research, literature reviews, and meta analyses is relatively low; thus, there is an urgent need to conduct these types of studies on recurrent glioma.
