Empirically Testing Some Main User-Related Factors for Systems Development Quality

The importance of user-related factors to system success has long been recognized by various researchers. This study attempts to test the importance of these variables as determinants of system quality. It has brought together some user-related variables (degree of user participation, user expertise, user/developer communication, user training, user influence, and user conflict) previously studied separately by different authors into a more cohesive model. Data from 228 systems have been used to test proposed relationships between the independent variables and system quality. The results confirm the importance of user participation, user training, and user expertise as significant variables for system quality. User/developer communication, user influence, and user conflict are found to possibly have only an indirect effect on system quality.
Intestinal bacterial overgrowth in CAPD patients with hypokalaemia.

OBJECTIVE We have previously demonstrated that hypokalaemia is a risk factor for enteric peritonitis in CAPD patients. The underlying mechanism is unclear, and there have been no similar reports. We hypothesized that hypokalaemia may result in dysmotility of the intestinal tract and in turn cause bacterial overgrowth and subclinical translocation of enteral bacteria. METHODS Uraemic patients undergoing CAPD in our hospital were enrolled in the study. Hypokalaemia was defined as a serum potassium (K) level < or = 3.5 mEq/L despite treatment for 1 month. A breath hydrogen test (BHT) was performed to detect if intestinal bacterial overgrowth was present. Blood samples were also collected for the study of inflammatory cytokines, including interleukin 1 (IL1), IL2, IL6, IL8, TNF-alpha and gamma-IFN. RESULTS A total of 68 patients were recruited. Hypokalaemia was present in 18 cases (26.5%, group 1), while 50 cases (group 2) had normal serum K levels. A higher prevalence of abnormal BHT was found in group 1 (27.8%), compared with group 2 (8.0%, P = 0.048). There was a trend towards a higher prevalence of abnormal BHT in diabetes mellitus (DM) patients with hypokalaemia (80.0%) compared with normal kalaemia (22.2%, P = 0.09), while no similar trends were found in non-DM hypokalaemic patients (7.7 versus 4.9%). When comparisons were made among different subgroups, patients with DM and hypokalaemia had a significantly higher prevalence of abnormal BHT compared to non-DM, normokalaemic patients (P < 0.0004) and non-DM, hypokalaemic patients (P = 0.008). Multivariate logistic regression analysis revealed that DM was an independent risk factor for abnormal BHT (odds ratio: 12.39, 95% CI: 2.25-68.20, P = 0.004). There was no significant difference in serum albumin, Kt/V, weekly creatinine clearance, pattern of peritoneal equilibrium test, C-reactive protein and various inflammatory cytokines between the two groups. CONCLUSION CAPD patients with hypokalaemia may have intestinal bacterial overgrowth. While both DM and hypokalaemia might contribute to this abnormality, only DM appeared to be the independent risk factor.
Why Are You Sharing Others' Tweets?: The Impact of Argument Quality and Source Credibility on Information Sharing Behavior

Twitter, a 140-character microblogging social networking service, has garnered attention from researchers and practitioners due to its considerable potential for information diffusion. Prior studies on Twitter typically focused on how user traits or relationships in a network affect information diffusion. However, few studies have been conducted on how posted messages in the service influence this phenomenon. Thus, this paper focuses on posted messages (a.k.a. “tweets”) and how they affect individuals’ information sharing behaviors on Twitter. A model for investigating tweet sharing behavior on Twitter is proposed based on dual-process theory and on social cognitive theory. Results from a preliminary test show that individuals’ perceptions of the argument quality and source credibility of a received tweet play a major role in their information sharing behavior via the perceived level of usefulness of the information and self-efficacy in regard to the sharing of a received tweet. Additionally, the existence of external links in a tweet moderates the impact of argument quality on users’ attitudes toward received tweets.

Women and homelessness, a complex multidimensional issue: findings from a scoping review

ABSTRACT Homelessness is an increasingly prevalent issue worldwide. Women represent the fastest growing segment of the homeless population and have differing needs to men. These differences need to be considered by service providers and other stakeholders working with homeless women. A scoping review was conducted to address the question “What is known about issues relating to homeless women in the existing literature? ” PubMed, PsycInfo, Embase, CINAHL, Scopus and Web of Science were searched up until March 2018 with no date limits. The final sample of articles included in this scoping study was 232 from which six themes were extracted: (1) pathways into homelessness, (2) trauma, victimization and adverse childhood experiences, (3) mental and physical health issues, (4) barriers to accessing treatment and experiences with service providers, (5) social support and life satisfaction and (6) strengths, hopes and leaving homelessness. This review suggests a strengths-based approach to addressing women’s homelessness. This approach emphasizes people’s self-determination and strengths and views clients as resilient to problems they encounter in their lives. Future research and service provision should take into account the complexities in the lives of homeless women and recognize the autonomy of women to move out of homelessness.
The Combination of Amoxicillin-Clavulanic Acid and Ketoconazole in the Treatment of Madurella mycetomatis Eumycetoma and Staphylococcus aureus Co-infection

Eumycetoma is a chronic progressive disabling and destructive inflammatory disease which is commonly caused by the fungus Madurella mycetomatis. It is characterized by the formation of multiple discharging sinuses. It is usually treated by antifungal agents but it is assumed that the therapeutic efficiency of these agents is reduced by the co-existence of Staphylococcus aureus co-infection developing in these sinuses. This prospective study was conducted to investigate the safety, efficacy and clinical outcome of combined antibiotic and antifungal therapy in eumycetoma patients with superimposed Staphylococcus aureus infection. The study enrolled 337 patients with confirmed M. mycetomatis eumycetoma and S. aureus co-infection. Patients were allocated into three groups; 142 patients received amoxicillin-clavulanic acid and ketoconazole, 93 patients received ciprofloxacin and ketoconazole and 102 patients received ketoconazole only. The study showed that, patients who received amoxicillin-clavulanic acid and ketoconazole treatment had an overall better clinical outcome compared to those who had combined ciprofloxacin and ketoconazole or to those who received ketoconazole only. In this study, 60.6% of the combined amoxicillin-clavulanic acid/ketoconazole group showed complete or partial clinical response to treatment compared to 30.1% in the ciprofloxacin/ketoconazole group and 36.3% in the ketoconazole only group. The study also showed that 64.5% of the patients in the ciprofloxacin/ketoconazole group and 59.8% in the ketoconazole only group had progressive disease and poor outcome. This study showed that the combination of amoxicillin-clavulanic acid and ketoconazole treatment is safe and offers good clinical outcome and it is therefore recommended to treat eumycetoma patients with Staphylococcus aureus co-infection.
Upregulation of SATB1 Is Associated with Prostate Cancer Aggressiveness and Disease Progression

Disease aggressiveness remains a critical factor to the progression of prostate cancer. Transformation of epithelial cells to mesenchymal lineage, associated with the loss of E-cadherin, offers significant invasive potential and migration capability. Recently, Special AT-rich binding protein (SATB1) has been linked to tumor progression. SATB1 is a cell-type restricted nuclear protein, which functions as a tissue-specific organizer of DNA sequences during cellular differentiation. Our results demonstrate that SATB1 plays significant role in prostate tumor invasion and migration and its nuclear localization correlates with disease aggressiveness. Clinical specimen analysis showed that SATB1 was predominantly expressed in the nucleus of high-grade tumors compared to low-grade tumor and benign tissue. A progressive increase in the nuclear levels of SATB1 was observed in cancer tissues compared to benign specimens. Similarly, SATB1 protein levels were higher in a number of prostate cancer cells viz. HPV-CA-10, DU145, DUPro, PC-3, PC-3M, LNCaP and C4-2B, compared to non-tumorigenic PZ-HPV-7 cells. Nuclear expression of SATB1 was higher in biologically aggressive subclones of prostate cancer cells with their respective parental cell lines. Furthermore, ectopic SATB1 transfection conferred increased cell motility and invasiveness in immortalized human prostate epithelial PZ-HPV-7 cells which correlated with the loss of E-cadherin expression. Consequently, knockdown of SATB1 in highly aggressive human prostate cancer PC-3M cells inhibited invasiveness and tumor growth in vivo along with increase in E-cadherin protein expression. Our findings demonstrate that SATB1 has ability to promote prostate cancer aggressiveness through epithelial-mesenchymal transition.
On the Resonance and Shelf/Open-Ocean Coupling of the Global Diurnal Tides

AbstractThe resonance of diurnal tidal elevations is investigated with a forward ocean tide model run in a realistic near-global domain and a synthesis of free oscillations (normal modes) computed for realistic global ocean geometries and ocean physics. As a prelude to performing the forward ocean tide simulations, the topographic wave drag, which is now commonly employed in forward ocean tide models, is tuned specifically for diurnal tides. The synthesis of global free oscillations predicts reasonably well the forward ocean diurnal tide model sensitivity to changes in the frequency, zonal structure, and meridional structure of the astronomical diurnal tidal forcing. Three global free oscillations that are important for understanding diurnal tides as a superposition of forced-damped, resonant, free oscillations are identified. An admittance analysis of the frequency sweep experiments demonstrates that some coastal locations such as the Sea of Okhotsk are resonant to diurnal tidal forcing. As in earlier wo.
WLC29-1: Addressing the Link Adaptation Problem for VoWLAN using Codec Adaptation

In this paper a scheme is proposed to deal with congestion problems that can arise due to Link Adaptation (LA) in Wireless Local Area Networks (WLANs) in the presence of VoIP traffic. The proposed scheme operates by first determining if LA has resulted in the system becoming congested. If not, no further action is taken. However, if, LA has resulted in an overloaded system, the voice codec of the handset which has undergone LA is adapted so as to restore the system to its earlier state, thereby alleviating the congestion. This is achieved by specifically adapting the codec so as to maintain approximately the same level of medium usage as was used prior to the LA. The proposed scheme was evaluated on an experimental test-bed and results show that the codec adaptation was very effective at overcoming the problem of LA.
The Investigation of the Relationship Between Mathematics and Science Literacy and Information and Communication Technology Variables

This study attempted to identify the information and communication technology items that affected students’ mathematics and science literacy scores by making use of the 2015 PISA data, The presence of numerous items related to ICT in the PISA and the administration of these items to large groups of people provides researchers with a large data source. However, researchers experience challenges in revealing the significant and beneficial data among the entire data set. So one of the most commonly used data mining method is the Chi-squared Automatic Interaction Detection method (CHAID), which is the decision tree method. As a result of the CHAID analysis, conducted to reveal the ICT items related to mathematics literacy scores, it was revealed that there was a significant relationship between mathematics literacy scores and the eight variables. For science literacy, there was a ten significant relationship variables. There is a relationship between high science and mathematics literacy scores and using digital devices at an early age as well as feeling comfortable with using digital devices at home. As an outcome of the CHAID algorithm, the realization of a significant reduction was achieved in the dimensionality of both models. The selected variables can be used for future research and development of new, parametric models. In the resulting model, apart from the reduction of the number of predictors, the reduction of their categories was also achieved.
An application of sensor networks with data mining to patient controlled analgesia

We designed an information integration system, iPCA, which combined wireless sensor networks with a data mining system, to help anesthesiologists provide better post-operative pain control. To reduce labor work and to collect analgesic usage information and physiological data efficiently, we connected three kinds of medical instruments with Zigbee nodes through IEEE 802.11 and Zigbee networks. We developed a positioning system that allowed the medical staff to monitor the patient's locations, so they could give immediate care when necessary. The data mining system in iPCA analyzed the patient data, and made reasonable predictions about the total analgesic dosage and the need for PCA control readjustments. We completed a prototype of iPCA, which could help the medical staff monitor the patient's health conditions and locations, and provide the anesthesiologists with useful hypotheses for better PCA control to increase patient satisfactions.
Autonomous demand response in heterogeneous smart grid topologies

Autonomous demand response (DR) is scalable and has minimal control overhead on utilities by encouraging users to minimize their own energy expenditure. While the prior results on autonomous DR are promising, they are all limited to homogeneous grid topologies, such as a microgrid or a small distribution feeder. In this paper, we take the first step to investigate autonomous DR in heterogeneous grid topologies, i.e., a macrogrid, where users who participate in autonomous DR programs are scattered across different buses. Our analysis requires expanding the existing autonomous DR to also include power flow analysis across the power grid. To gain insight, we perform two analytical case studies and show that the results can be very different from the results previously reported on homogeneous autonomous DR systems. We also provide recommendations to design efficient, fair, and practical autonomous demand response systems in heterogeneous smart grid topologies.
Bridging the Primary to Secondary School Mathematics Divide: Teachers’ Perspectives

The transition from primary to secondary school is regarded as one of the most difficult crossings in students' educational careers. The move, which typically occurs between the ages of twelve and fourteen, can be particularly pronounced for mathematics. This article describes the results of a questionnaire distributed in the Republic of Ireland in which the views of primary and secondary teachers were ascertained with regard to the transition process. A total of 298 primary and 173 secondary teachers completed the questionnaire. Results showed that teachers at both levels identified similar issues such as a lack of continuity between curricula, a lack of knowledge of each other's curriculum and a lack of communication between both levels. Many of the teachers' suggestions on how the transition process could be improved centred on these issues, as well as highlighting a need to provide joint professional development opportunities for teachers.
2) Onchocerciasis

Although onchocerciasis in cattle and horses in Japan had been noted in the veterinary field since the early 1950s, research on human onchocerciasis that is caused by Onchocerca volvulus was carried out only in the early 70s. It began when I did a brief study of skin test for onchocerciasis cases in Guatemala, Central America, in collaboration with Dr. H. Figueroa [1] using a Dirofilaria antigen [2]. Dr. Figueroa was an admirer of Dr. R. Robles, who discovered the presence and distribution of onchocerciasis on the American continents. Later on, many Japanese parasitologists participated in this field of research through the international health projects sponsored by Japan’s ODA (Overseas Development Assistance) agency (Overseas Technical Cooperation Agency (OTCA)/ and later Japan International cooperation Agency (JICA)) that were implemented in Ethiopia (after1969), Guatemala (after 1975) and Nigeria (after 1983).
Improving Universal Classroom Practices Through Teacher Formative Assessment and Coaching

This article presents the Classroom Strategies Coaching (CSC) Model, a data-driven coaching approach that uses teacher formative assessment data to drive improvements in universal practices. The classroom strategies assessment system (CSAS), a formative assessment of evidence-based instructional and behavioral management practices was used to facilitate the coaching process. Results from 32 elementary school teachers who received brief coaching after participating as waitlist controls in a randomized controlled trial are presented. Teachers’ practices remained stable across baseline periods. Following coaching, teachers displayed improvements toward their behavioral management goals (e.g., ds = .50–.83). Results also showed meaningful reductions in the overall need for change in instruction (d = .88) and in behavior management practices (d = .68) at postintervention. Findings illustrate the benefits of integrating teacher formative assessment in coaching to improve teaching practices. Implications for practice and future directions are outlined.
Title: Selection for silage yield and composition did not affect genomic diversity within

Maize silage is a forage of high quality and yield, and represents the second 30 most important use of maize in the U.S. The Wisconsin Quality Synthetic (WQS) maize 31 population has undergone five cycles of recurrent selection for silage yield and 32 composition resulting in a genetically improved population. The application of high-33 density molecular markers allows breeders and geneticists to identify important loci 34 through association analysis and selection mapping, as well as monitor changes in the 35 distribution of genetic diversity across the genome. The objectives of this study were: 1) 36 Identify loci controlling variation for maize silage traits through association analysis and 37 the assessment of selection signatures. 2) Describe changes in the genomic distribution of 38 gene diversity through selection and genetic drift in the WQS recurrent selection 39 program. We failed to find any significant marker-trait associations using the historical 40 phenotypic data from WQS breeding trials combined with 17,719 high-quality, 41 informative single nucleotide polymorphisms. Likewise, no strong genomic signatures 42 were left by selection on silage yield and quality in the WQS despite genetic gain for 43 these traits. These results could be due to the genetic complexity underlying these traits, 44 or the role of selection on standing genetic variation. Variation in loss of diversity 45 through drift was observed across the genome. Some large regions experienced much 46 greater loss in diversity than what is expected, suggesting limited recombination 47 combined with small populations in recurrent selection programs could easily lead to 48 fixation of large swaths of the genome.
Unified quantitative characterization of epithelial tissue development

Understanding the mechanisms regulating development requires a quantitative characterization of cell divisions, rearrangements, cell size and shape changes, and apoptoses. We developed a multiscale formalism that relates the characterizations of each cell process to tissue growth and morphogenesis. Having validated the formalism on computer simulations, we quantified separately all morphogenetic events in the Drosophila dorsal thorax and wing pupal epithelia to obtain comprehensive statistical maps linking cell and tissue scale dynamics. While globally cell shape changes, rearrangements and divisions all significantly participate in tissue morphogenesis, locally, their relative participations display major variations in space and time. By blocking division we analyzed the impact of division on rearrangements, cell shape changes and tissue morphogenesis. Finally, by combining the formalism with mechanical stress measurement, we evidenced unexpected interplays between patterns of tissue elongation, cell division and stress. Our formalism provides a novel and rigorous approach to uncover mechanisms governing tissue development. DOI: http://dx.doi. org/10.7554/eLife.08519. 001
The semispin groups in string theory

In string theory, an important role is played by certain Lie groups which are locally isomorphic to SO(4m), m⩽8. It has long been known that these groups are actually isomorphic not to SO(4m) but rather to the groups for which the half-spin representations are faithful, which we propose to call Semispin(4m). (They are known in the physics literature by the ambiguous name of “Spin(4m)/Z2. ”) Recent work on string duality has shown that the distinction between SO(4m) and Semispin(4m) can have a definite physical significance. This work is a survey of the relevant properties of Semispin(4m) and its subgroups.
