The Impact of Organization’s Dynamic Capabilities on Information Systems Project’s Success in the Jordanian Telecommunication Sector

Information Systems (IS) ecosystems change rapidly which makes IS projects’ success challenging. Project success eventually impacts organizational competitive advantage which is a major concern for telecommunication organizations. dynamic capabilities (DC) are needed for organizations to continually transfer, shift and reallocate their organizational capabilities according to the dynamic changes occur in the surrounding ecosystem. This paper aims at investigating the impact of organizational dynamic capabilities (DC) on IS project success in telecommunication organizations in Jordan. A survey is used as an instrument of research in order to achieve the research’s main objectives. The study is carried out by surveying (233) employees who participated in IS projects. The survey paragraphs are validated and approved by a panel of experts. Consequently, data extracted from the questionnaire is statistically analyzed using the Statistical Package for the Social Sciences (SPSS) and AMOS applications. The findings reveal that employees in telecommunication organizations recognize and apply the concept of DC (Dynamic Capabilities) at a (High) level. Results also show that rate of IS projects success in telecommunication organizations in Jordan is (High). It also shows that DC along with its four main dimensions, contribute in all three dimensions of IS project, and that project capabilities play a major role mediating the impact of DC on IS project success. The study has several contributions on both academic and practical levels. For example, it links DC for becoming basis for software projects success.
The effects of kinesiotaping on wrist extensor strength using an isokinetic device in patients with chronic lateral epicondylitis: A randomized-controlled trial.

Objectives This study aims to evaluate short-term effects of kinesiotaping (KT) on pain, arm function, grip strength, and wrist extensor strength in patients with chronic lateral epicondylitis (LE). Patients and methods A total of 48 patients (32 females, 16 males years; mean age 47.6 years; range 27 to 67 years) with chronic LE were randomly assigned to either KT group (n=27) or sham group (n=21). Pain intensity with visual analog sclae (VAS), arm pain and function with Patient-Rated Tennis Elbow Evaluation Questionnaire (PRTEE), grip strength with hand dynamometer, and wrist extensor strength by an isokinetic device were evaluated before and at the end of the treatment. The KT stayed on for five days and the procedure was repeated for three times. Results Although pain and functional levels of patients with chronic LE were significantly improved both with KT (pain, p=0.001; function, p=0.001) and sham groups (pain, p=0.001; function, p=0.001), no significant difference was observed between the groups. Conclusion Both KT and sham taping provided similar improvement in pain relief through arm functions in patients with chronic LE.
The estrogenic pathway modulates non-breeding female aggression in a teleost fish

Aggressive behaviors are widespread among animals and are critical in the competition for resources. The physiological mechanisms underlying aggression have mostly been examined in breeding males, in which gonadal androgens, acting in part through their aromatization to estrogens, have a key role. There are two alternative models that contribute to further understanding hormonal mechanisms underlying aggression: aggression displayed in the non-breeding season, when gonadal steroids are low, and female aggression. In this study we approach, for the first time, the modulatory role of estrogens and androgens upon non-breeding aggression in a wild female teleost fish. We characterized female aggression in the weakly electric fish Gymnotus omarorum and carried out acute treatments 1 h prior to agonistic encounters with either an aromatase inhibitor or an antagonist of androgen receptors. Aromatase inhibition caused a strong distortion of aggressive behavior whereas anti-androgen treatment had no effect on behavior. Territorial non-breeding aggression in female G. omarorum is robust and depended on rapid estrogen actions to maintain high levels of aggression, and ultimately reach conflict resolution from which dominant/subordinate status emerged. Our results taken together with our own reports in males and the contributions from non-breeding aggression in bird and mammal models, suggest a conserved strategy involving fast-acting estrogens in the control of this behavior across species. In addition, further analysis of female non-breeding aggression may shed light on potential sexual differences in the fine tuning of social behaviors. Highlights Female Gymnotus omarorum displayed robust territorial aggression in lab settings. Acute treatment with aromatase inhibitor lowered aggression levels. Aromatase inhibition increased first attack latency and decreased conflict resolution. Acute treatment with anti-androgens showed no effects. This is the first report of estrogens underlying teleost non-breeding female aggression.
Does Terrorism Trigger Online Hate Speech? On the Association of Events and Time Series

Hate speech is ubiquitous on the Web. Recently, the offline causes that contribute to online hate speech have received increasing attention. A recurring question is whether the occurrence of extreme events offline systematically triggers bursts of hate speech online, indicated by peaks in the volume of hateful social media posts. Formally, this question translates into measuring the association between a sparse event series and a time series. We propose a novel statistical methodology to measure, test and visualize the systematic association between rare events and peaks in a time series. In contrast to previous methods for causal inference or independence tests on time series, our approach focuses only on the timing of events and peaks, and no other distributional characteristics. We follow the framework of event coincidence analysis (ECA) that was originally developed to correlate point processes. We formulate a discrete-time variant of ECA and derive all required distributions to enable analyses of peaks in time series, with a special focus on serial dependencies and peaks over multiple thresholds. The analysis gives rise to a novel visualization of the association via quantile-trigger rate plots. We demonstrate the utility of our approach by analyzing whether Islamist terrorist attacks in Western Europe and North America systematically trigger bursts of hate speech and counter-hate speech on Twitter.
Strength Characteristics of Lateritic Soil Stabilized with Recycled Concrete

This study investigates the use of recycled concrete as a stabilizing agent for lateritic soil. The pulverized recycled concrete was added to the soil in varying proportions of 2, 4, 6, 8, 10 and 12% by weight of the lateritic soil samples. The compaction test on the modified soil showed that the Maximum dry density (MDD) increased by 5.07% from the initial MDD value of 1732.18 kg/m 3 when the soil sample was stabilized with 10% recycled concrete. Increase in the recycled concrete to 12% by weight of the soil sample had a percentage increase of 4% from the initial MDD value. The unsoaked California Bearing Ratio (CBR) value of the soil increased by 111.2% from the initial CBR value of 23.1% when the soil sample was stabilized with 10% recycled concrete. An increase in the recycled concrete content to 12% by weight of the soil sample gave an increase of 94.4% from the initial CBR value. The Unconfined Compressive Strength (UCS) experienced an increase of 62.5% from the initial UCS value of 190.77 kN/m 2 when the soil sample was stabilized with 10% recycled concrete by weight of the soil sample. Increase in the recycled concrete content to 12% by weight of the soil sample gave a percentage increase of 57.4% from the initial UCS value. The 10% recycled concrete (by weight of soil sample) produced the peak values of 310.08kN/m 2 and 48.8% for the unconfined compressive strength and California bearing ratio respectively.

University of Birmingham Frailty and the Immune System

Frailty describes a medical syndrome that confers increased vulnerability to disproportionate changes in health status following minor stressors. With loss of homeostatic reserve in multiple physiological systems, frailty conveys an increased risk of adverse health outcomes. Despite the lack of a clear universal definition, the utilisation of two landmark operational models has allowed a rapid expansion in frailty-centred research. The pathophysiology of frailty is yet to be elucidated in the literature, but a critical role for a heightened inflammatory state is hypothesised. Raised levels of pro-inflammatory cytokines are associated with frailty, with emerging evidence relating their biochemical action with development of the frailty phenotype. Dysregulation of both the innate and adaptive immune system are key components of the frailty syndrome. Remodelling of the T cell compartment and upregulated inflammatory pathways are theorised to propagate the heightened inflammatory state critical in the frailty syndrome. Increased neutrophil counts, in conjunction with ineffective neutrophil migration associated with age, is theorised to produce tissue damage and secondary inflammation conducive of the inflammatory picture in frailty. Beyond gold improving ability and showing beneficial Vitamin with proposed treatments all provide promising areas for future therapeutic intervention.
Pump Up the Volume: Processing Large Data on GPUs with Fast Interconnects

GPUs have long been discussed as accelerators for database query processing because of their high processing power and memory bandwidth. However, two main challenges limit the utility of GPUs for large-scale data processing: (1) the on-board memory capacity is too small to store large data sets, yet (2) the interconnect bandwidth to CPU main-memory is insufficient for ad hoc data transfers. As a result, GPU-based systems and algorithms run into a transfer bottleneck and do not scale to large data sets. In practice, CPUs process large-scale data faster than GPUs with current technology. In this paper, we investigate how a fast interconnect can resolve these scalability limitations using the example of NVLink 2.0. NVLink 2.0 is a new interconnect technology that links dedicated GPUs to a CPU@. The high bandwidth of NVLink 2.0 enables us to overcome the transfer bottleneck and to efficiently process large data sets stored in main-memory on GPUs. We perform an in-depth analysis of NVLink 2.0 and show how we can scale a no-partitioning hash join beyond the limits of GPU memory. Our evaluation shows speed-ups of up to 18x over PCI-e 3.0 and up to 7.3x over an optimized CPU implementation. Fast GPU interconnects thus enable GPUs to efficiently accelerate query processing.
The prevalence of sarcopenia risk and associated factors in patients aged 65-79 years living in a district of Izmir province of Turkey.

Objectives This study aims to investigate the prevalence of sarcopenia risk and associated factors in a community-dwelling elderly population in a district of Izmir province of Turkey. Patients and methods This cross-sectional study used a cluster sampling method to define sarcopenia risk and associated factors in population aged 65-79 years in Balcova district and a total of 254 participants (114 males, 140 females; mean age 70.0 years; range 65 to 79 years) were included between October 2014 and December 2014. The dependent variables were low gait speed (LGS), low grip strength (LGrS), having both LGS and LGrS, sarcopenia risk according to the European Group on Sarcopenia for Older People (EWGSOP) algorithm. The independent variables were socio-demographic and socio-economic variables, health-related behavioral factors, and health status variables. The gait speed was measured on a four-meter length with a stopwatch. The grip strength was measured using a hand-held dynamometer. The logistic regression models were used to identify associated risk factors for sarcopenia. Results The prevalence of LGS was found to be 45.0%, LGrS to be 49.8%, having both LGS and LGrS to be 30.1%, and sarcopenia risk according to EWGSOP to be 64.8%. The main associated factors of having any sarcopenia risk were increasing age and having a sedentary lifestyle or being underactive. Conclusion Our study results show that sarcopenia risk is high in a community-dwelling elderly population living in Balcova district of Izmir province of Turkey. Physical activity levels of elderly should be increased to decrease this high burden.
PERFORMANCE OF EARTHQUAKE DAMAGED BEAMS AND EFFECTIVENESS OF REPAIR VIA EPOXY INJECTION

A significant challenge for engineers following the 2010-11 Canterbury earthquakes was the decision making and assessment process surrounding moderately damaged reinforced concrete (RC) structures. Similarly, in the aftermath of the 2016 Kaikoura earthquakes, these issues were highlighted, leaving engineers and building owners with limited guidance on the reparability of these buildings, particularly in the Wellington region. Four beam-column assemblies, exhibiting low to moderate damage levels after the 2016 Kaikoura earthquake, were extracted from a RC building in Wellington. Specimens were tested at the University of Auckland to assess their residual stiffness, strength and deformation capacity. One specimen was repaired using epoxy injection and repair mortar by experienced contractors. Results from the tests indicate that the damaged specimens maintained their strength and deformation capacity and demonstrate the impact of epoxy injection on recovery of stiffness in the elements.
Infant Feeding Practice and Associated Factors among HIV Positive Mothers in Jigjiga Town, Ethiopia

Introduction: Breastfeeding is a pillar of child survival. However, since the early 1980’s when it was discovered that HIV could be transmitted to infants through human milk, the healthfulness of breastfeeding has been questioned because of the risk of mother-to-child transmission of HIV. The rate of transmission through breast feeding of the disease is 5-20%. The two postnatal strategies to prevent MTCT are exclusive replacement feeding and exclusive replacement feeding. Nonetheless, some factors like HIV status disclosure, socio-cultural influence and knowledge of the mother about MTCT through breast feeding are known to influence feeding practices. Objective: Infant feeding practice and associated factors among HIV positive mothers who are attending health institution in Jigjiga town, Ethiopia. Method: A cross sectional quantitative study was conducted among HIV positive mothers in health institution with ART and PMTCT facilities in Jigjiga town from February to March, 2015. Bivariate and a multiple logistic regression were employed to see the relationship between the dependent and independent variables. Result: The current study demonstrated that (93.6%) of the respondents were practices exclusive breast feeding while small proportion (6.4%) of HIV positive mothers had practice of mixed feeding. Concerning feeding practice after delivery, (6.4%) mothers gave their infants liquids or food before initiating breastfeeding. As to this finding revealed mothers decision on infant feeding was influenced by various predictors. Regarding to disclose HIV status, those respondents who were less disclosed their HIV status was significantly associated with mixed feeding practice. Conclusion and Recommendations: As to this finding revealed after delivery, (6.4%) mothers gave their infants liquids or food before initiating breastfeeding. Health workers and supporters should provide continuous infant feeding options to HIV positive mothers to enhance compliance to exclusive breastfeeding and encourage and assist HIV positive mothers to disclose their HIV status to their husband/spouse. To select safer infant feeding options, mothers’ decision should be respected, and influencing mothers’ to introduce other food to the infant should be avoided.
The MTA: Child and Adolescent Psychiatry in a New Century

L ast autumn, the Annual Meeting ofthe Academy ofChild and Adolescent Psychiatry in Anaheim was steeped in anticipation of the first peek at the results of the Multimodal Treatment Study of Children With Attention-Deficit Hyperactivity Disorder (ADHD) (the MTA study). Most child psychiatrists knew about the study that was undertaken by the National Institute of Mental Health and 6 collaborating academic sites from numerous publications and presentations outlining the design and method of the trial. This randomized control trial compared pharmacological, behavioural, and combined treatment strategies with a community control condition in the most elaborate investigation of treatment of any kind in children's mental health. The net result was an outstanding piece ofresearch that will be published in as many as lOO journal articles over the next few years and which will have a far-reaching impact on practice.
Bacteriological Evaluation of Vaginal Discharges in Cows with Endometritis and Clinically Healthy Heifers In Assiut Governorate

The study was carried out for the isolation and identification of vaginal bacterial flora of 36 healthy and diseased cows in a freisian dairy farm in Assiut Governorate. The animals were divided into 4 categories: the first included 6 repeat breeder cows with endometritis after last birth, the second included 13 pregnant heifers, the third included 12 heifers at the age of mating and the last one included 5 primiparus cows. 50 bacterial strains were identified from the vaginal discharges. These isolates were: 15 (30%) E.coli , 11(22%) Staphylococcus epidermidis, 2 (4%) Staphylococcus saprophyticus, 1 (2%) Streptococcus pneumoniae, 10 (20%) Corynebacterium sp. 8 (16%) Anthracoid bacilli, 1 (2%) from each of Enterobacter aerogenes, Klebsiella oxytoca and Citrobacter diversus. Antibiotic sensitivity tests were carried out against the isolated microorganisms using ten antibiotics. It was found that cibrofloxacin was highly effective against most strains (92%) followed by Gentamycin (90%) and amoxycillin (74%) while cloxacillin and duricef were not effective (0%).

Social organization and homicide rates in Chicago neighborhoods: the role of structural stability and change

ABSTRACT A life-course perspective on neighborhood effects suggests that levels of and changes in neighborhood structural conditions may impact neighborhood social organization, collective efficacy, and reciprocated exchange, with implications for changes in homicide rates. Results indicate changes in neighborhood disadvantage – though not in immigrant concentration or residential stability – disrupt both reciprocated exchange and collective efficacy. However, neither mechanism appears to mediate the change-homicide relationship, nor do the two mediators significantly interact in their association with homicide rates. Findings suggest both contemporary and historical neighborhood disadvantage is significantly related to homicide rates, supporting a dynamic view of the links between conditions, social mediators, and homicide.
China’s dash for gas: local challenges and global consequences

ABSTRACT The recent 2017–18 “dash for gas” captured global attention, but also exposed critical failings in China’s gas market. The 2019 lull imposed by the Government reflects the need to address local challenges. This paper analyzes the prospects for demand growth and assesses the various ways in which that demand can be met. There is considerable uncertainty surrounding demand growth, with cost competitiveness being the determining factor. Equally, although China has significant natural gas reserves, they are largely unconventional and present significant geological and technical challenges; with domestic production growth failing to keep pace as demand import dependence increases. China’s gas imports are met by pipeline gas from Central Asia and Myanmar and Liquified Natural Gas (LNG) from avariety of countries. The Power of Siberia pipeline started deliveries of Russian in late 2019. However, plans to expand Central Asian imports have disappointed and China may agree to asecond pipeline from Russia or increase its LNG imports. Asimple “gas balance model” is used in the final discussion and conclusions to explore future developments and their consequences for global gas security.
Comparing Authoritarian Publics: The Benefits and Risks of Three Types of Publics for Autocrats

Researchers comparing political communication across non-democratic contexts presently lack a widely acknowledged theoretical framework to guide their efforts. In order to fill in this gap, this essay develops a theoretical account that proposes comparing not authoritarian media systems, but “authoritarian publics. ” Drawing on theories of the multiple public sphere, two typologies are delineated: (a) a three-fold typology of partial publics, operating within authoritarian regimes and (b) a three-fold typology of “publics-at-large,” to be distinguished across authoritarian regimes. As it is argued, the publics-at-large of authoritarian regimes can be composed of three types of partial publics: (a) uncritical, (b) policy-critical, and (c) leadership-critical publics. With reference to political science literature about the emergence of formally democratic institutions in non-democratic regimes, critical publics are interpreted as institutions that help autocrats carry out important tasks. The benefits and risks associated with critical publics for autocrats are comparable to those of other pseudo-democratic institutions.
