Feedbacks between Hydrological Processes in Tropical South America and Large-Scale Ocean–Atmospheric Phenomena

Abstract The hydroclimatology of tropical South America is strongly coupled to low-frequency large-scale oceanicand atmospheric phenomena occurring over the Pacific and the Atlantic Oceans. In particular, El Nino–SouthernOscillation (ENSO) affects climatic and hydrologic conditions on timescales ranging from seasons to decades.With some regional differences in timing and amplitude, tropical South America exhibits negative rainfall andstreamflow anomalies in association with the low–warm phase of the Southern Oscillation (El Nino), and positiveanomalies with the high–cold phase. Such dependence is illustrated in the hydroclimatology of Colombia throughseveral empirical analyses: correlation, empirical orthogonal functions, principal component, and spectral analysis, and discussion of the major physical mechanisms. Observations show that ENSO’s effect on river dischargesoccurs progressively later for rivers toward the east in Colombia and northern South America. Also, the impactsof La Nina are more pronounc.
Organizational, Financial and Regulatory Challenges of Implementing Hospital Information Systems in Saudi Arabia

Hospital information systems (HIS) are a core component of the healthcare system. These systems have been in use for decades worldwide and for many years now in the Middle East. Many hospitals in Saudi Arabia started to adopt HIS, but still faced with many challenges. On top of these come the organizational, financial and regulatory challenges. The main objective of this study is to identify, analyze and evaluate these three categories of challenges perceived by healthcare professionals in order to provide decision makers with suggestions and recommendations on proper actions. The study used survey methods to collect data from healthcare professionals at two main Saudi hospitals known for their experience implementing HIS, and then analyzed the results to describe and evaluate challenges. The study validated 10 organizational, 6 financial and 6 regulatory challenges and explored participants’ experiences regarding each. The study sorted challenges importance from the most to the least; financial challenges came first, then organizational challenges while regulatory challenges came last. Government hospital users had more concerns than private, regarding all of the three categories of challenges. Some demographic variables, such as age, gender, experience and profession, had significant influence on the perception of healthcare professionals towards different challenges. The study recommends providing or outsourcing the required experience of hospital management to choose, to implement and to evaluate HIS performance. Redesigning workflows to match HIS is a viable option for successful implementation. Clear time frame for implementation is very essential. Allocating proper and enough investments, especially at the initial phase of implementation, is important. Feasibility studies on benefits versus costs of implementing and using HIS are crucial for decision makers. Much work still to be done on developing regulations, policies and procedures on both hospital and national levels to govern adoption, implementation and utilization of HIS.

In vitro anti-tyrosinase and anti-elastase activity of collagen from sea cucumber (Holothuria leucospilota)

Collagen is the main structural component of connective tissues in vertebral and invertebral animal tissues and organs. The collagen isolated from the body wall of sea cucumber (Holothuria lecospilota) can be used in the pharmaceutical field. The research aimed at isolating collagen from the sea cucumber body wall and testing the anti-tyrosinase and anti-elastase activity. This was done by isolation of collagen by soaking the body wall of sea cucumber using Tris-HCl-EDTA 0.1 M and dialyzing using 0.5 M acetic acid. The step was followed by characterization of collagen using FT-IR spectrophotometer and sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The resulting collagen was tested for anti-tyrosinase and anti-elastase in vitro. The research showed that the resulting collagen was of the amide group with molecular weight of 166.43 and 138.35 kDa, showing α1 and α2 chains. Anti-tyrosinase activity test showed an IC50 value of 1.20 mg/mL, while anti-elastase activity test showed an IC50 value of 125 µg/mL. The collagen isolated from the sea cucumber has weak anti-tyrosinase and moderate anti-elastase activity. Key words: Crude collagen, anti-tyrosinase, anti-elastase, sea cucumber (Holothuria leucospilota).
Zinc and Copper Levels in Patients with Primary Hypertension and Normotension

One of the causes of primary hypertension is an exposure to free radicals. The formation of free radicals in the body can be prevented by taking antioxidants. Zinc and copper are cofactors of endogenous antioxidant enzyme superoxide dismutase. This study aimed to analyze the differences of zinc and copper levels in primary hypertensive and normotensive patients. This was an analytical observational study with cross sectional design and simple random sampling method. Subjects were patients aged 40-70 years at Haji General Hospital consisting of 15 primary hypertensive patients and 15 normotensive individuals (comparison group). Data was collected through interviews and laboratory test of blood samples. Zinc and Copper serum concentrations were measured by AAS. Data were analyzed by chi-square and independent samples t-test. The results showed that the mean levels of zinc and copper in primary hypertensive patients was lower than normotensive. However, statistically there was no difference in zinc serum levels (p=0.852) in the two groups, and there was a significant difference in copper serum levels (p=0.032). It can be concluded that there were differences in copper serum levels between the two groups but not with the levels of zinc.
Metaphors of History Teachers Candidates in Turkey on Teaching Profession.

The study aims to determine the reason for choosing the teaching profession identifying how history teacher candidates perceive the concepts of "teacher" and "teaching". The study was conducted with 115 history teachers enrolled in an initial teacher training programme in a university located in Turkey’s Central Anatolia Region in the 2014-2015 academic year. To investigate the candidate teachers’ perceptions of the teaching profession, the research participants filled in blank space from a questionnaire administered by the researchers. The collected data was analysed using the content analysis method and this gave rise to specific metaphors with associated categories. Thus, 19 metaphors and 6 categories for the teacher concept; 26 metaphors and 7 categories for teaching; 15 reasons and 3 categories for the reasons of choosing the teaching profession emerged. Research findings illustrate that the candidate history teachers’ perception of the teaching profession are positive. However, the participants used predominantly negative metaphors, in describing the difficulties history teacher candidates encounted regarding “teaching”. In relation to teaching profession choices, the most occurring reason was the love for the profession; other factors affecting the candidates’ preference were the reasons articulated in the categories of “need” and “responsibility”.
Does Distance Learning Work? A Large Sample, Control Group Study of Student Success in Distance Learning.

s appeared in major distance education journals and as dissertations during the 1990-1999 period (Berge and Mrozowski, 2001). More than one hundred of these studies focused upon various measures of student success (such as grades, subsequent academic success, and persistence) in distance learning courses. Several asked the specific question addressed in this paper: Why do some students do better than others, at least as measured by the grade e-Journal of Instructional Science and Technology Volume 8, No. 1, 2005
Effects of changes in number, identity and abundance of habitat-forming species on assemblages of rocky seashores

Understanding the relationship between variation in biodiversity and the alteration of ecosystem processes and stability has become a central ecological issue during the last decade. A large number of experimental and theoretical studies have focused on the effects of changes in spe- cies richness and identity, while the role of variation in species abundance has received less attention in biodiversity experiments. By using an experimental design that effectively separates the effects of species richness and identity, while controlling for variation in species abundance, we examined the consequences of loss of 2 habitat-forming species (the canopy alga Cystoseira compressa and the mussel Mytilus galloprovincialis) in Mediterranean low-shore assemblages of algae and inverte- brates. Results revealed significant effects associated with changes in number and identity of habitat- forming species on other organisms. The magnitude and direction of these effects, however, changed as a function of the abundance of manipulated species. Our findings indicate how changes in biodi- versity of even 2 species can result in complex effects, stressing the importance of investigating non- random loss of habitat-forming species and the need to consider density-dependent effects in biodi- versity experiments, particularly when experiments are undertaken in systems like rocky shores, where density-dependent effects are pervasive.
Economic Choices Among Different Groups According to the Cognitive Economics and Social Judgement Theory

Decision making, social judgement and human reasoning process is an important research area for experimental micro-economics. Social judgement happens with previous learning, reasoning and decision making processes and by the synchronized appearance of these cognitive functions, so the brain relates decision utility to anticipated and experienced utility. In the brain system, this neural synchronization is realized by the executive functions which seem to be located in the limbic system and frontal lobes. These neuroscientific researchs are also effective on social sciences and ethical discussions. This study generally provides examples from the relevant literature about the instruments used by the neurological applications to investigate the behaviours of individuals, how they are used to study interactions between individuals and how they can be used in modelling social dynamics as well as evaluating the effects of these studies on individuals and society. In this study, some behavioral perspectives on trust and reciprocity, fairness and altruism, justice and social norms were searched with the help of behavioral experiments presented in the game theory literature. The research part of the study includes the design, statistical results and findings of the experiment that we applied to the undergraduate students and public staff in Istanbul. The data was evaluated by ANOVA difference tests were conducted. The results of the analyses show that individuals don’t only try to behave rationally when they make economic judgements but also take decisions by involving their educations and social roles into the judgement processes. There are also significant differences between university students and public employees. The last part discusses the practical results of these studies and their possible effects on social sciences. One of the basic criticisms on the experimental studies of economic decision making is that the experiments in a laboratory environment may systematically vary from the behaviours in real life.
Bayesian Exponential Survival Model in the Analysis of Unemployment Duration Determinants

The primary objective of the work is to identify demographic and socio-economic factors influencing the unemployment duration in the recent period in Poland. Different ap- proaches to the problem have been applied. In this paper we have used a survival parametric model in Bayesian approach. The following determinants have been concerned in the model: sex, marital status, education level, information about continuing an education, region of Poland, and age of respondent. The empirical analysis is based on "Household budgets in 2008" survey of Central Statistical Office and indicates the main factors influencing unemployment duration.
Bimodal Formation Time Distribution for Infall Dark Matter Halos

We use a 200 a-side N-body simulation to study the mass accretion history (MAH) of dark matter halos to be accreted by larger halos, which we call infall halos. We define a quantity to characterize the MAH of infall halos, where and are the accretion and formation redshifts, respectively. We find that, at given , their MAH is bimodal. Infall halos are dominated by a young population at high redshift and by an old population at low redshift. For the young population, the distribution is narrow and peaks at about 1.2, independent of , while for the old population, the peak position and width of the distribution both increase with decreasing and are both larger than those of the young population. This bimodal distribution is found to be closely connected to the two phases in the MAHs of halos. While members of the young population are still in the fast accretion phase at zpeak, those of the old population have already entered the slow accretion phase at . This bimodal distribution is not found for the whole halo population, nor is it seen in halo merger trees generated with the extended Press–Schechter formalism. The infall halo population at are, on average, younger than the whole halo population of similar masses identified at the same redshift. We discuss the implications of our findings in connection to the bimodal color distribution of observed galaxies and to the link between central and satellite galaxies.
Residential Mortgage Default: The Roles of House Price Volatility, Euphoria and the Borrower’s Put Option

House price volatility; lender and borrower perception of price trends, loan and property features; and the borrower’s put option are integrated in a model of residential mortgage default. These dimensions of the default problem have, to our knowledge, not previously been considered altogether within the same investigation framework. We rely on a sample of individual mortgage loans for 20 counties in Florida, over the period 2001 through 2008, third quarter, with housing price performance obtained from repeat sales analysis of individual transactions. The results from the analysis strongly confirm the significance of the borrower’s put as an operative factor in default. At the same time, the results provide convincing evidence that the experience in Florida is in part driven by lenders and purchasers exhibiting euphoric behavior such that in markets with higher price appreciation there is a willingness to accept recent prior performance as an indicator of future risk. This connection illustrates a familiar moral hazard in the housing market due to the limited information about future prices.
Internet usage as a learning tool among Malaysian universities students

The study examined the factors influencing the usage of the Internet for academic purposes amongst final year business students in public universities in Malaysia. The research model employed the variables from the theory of acceptance model (TAM), namely perceived usefulness, perceived ease of use, intention, and behavior. A structured, self-administered questionnaire was used to elicit responses from a randomly selected sample of 422 respondents. Regression analyses were employed to analyze the data. The results indicated that perceived ease of use had an effect on the perceived usefulness (at the R2 value of 0.14), which in turn influenced studentsâ€™ intention to use the Internet for academic purposes. In addition, with a significant Ã¢ value of 0.367, perceived usefulness was also found to mediate the impact of perceived ease of use on studentsâ€™ intention to use the Internet. Finally, intention was also found to influence the actual behavior at 45 percent. In view of the results, it can be concluded that the Internet application is a useful tool to assist studentsâ€™ learning. Thus, academicians should be open and opportunistic in applying this dynamic tool in their teaching.
Funktion von Abp1, einem Signal-responsiven Verbindungsglied zwischen Aktinzytoskelett und Membrantransport, in neuronaler Morphologie = Function of Abp1, a signal-responsive linker between actin cytoskeleton and membrane transport, in neuronal morphology

Polymerization and organization of actin into complex superstructures is indispensable for structure and function of neuronal networks. This work shows that the F-actin-binding protein 1 (Abp1), which controls Arp2/3 complex-mediated actin nucleation via the neural Wiskott-Aldrich syndrome protein (N-WASP) and binds to postsynaptic scaffold proteins of the ProSAP/Shank family, has a profound impact on synaptic organization. RNAi mediated knock-down of Abp1 expression results in changes in early axon development virtually identical to Arp2/3 complex inhibition, i.e. a selective increase of axon length. This work reveals an essential role of Abp1 and its cooperation with Cdc42 in N-WASP-induced rearrangements of the neuronal cytoskeleton. Secondly, Abp1 controls the formation and morphology of dendritic spines harboring the postsynaptic signal reception and transduction apparatus. Overexpression of the two Abp1 F-actin-binding domains increases the length of spines but dramatically reduces mushroom-type spine density, due to lack of the Abp1 SH3 domain. In contrast, overexpression of full-length Abp1 increases mushroom spine and synapse density. This suggests that both actin-binding and SH3 domain interactions are crucial for Abp1’s role in spine maturation. Abp1 hereby works in close conjunction with ProSAP1/Shank2 and ProSAP2/Shank3, because ProSAP2 RNAi suppressed Abp1 effects, and the ProSAP/Shank-induced increase of spine head width is further promoted by Abp1 cooverexpression and reduced upon Abp1 knock-down. Spine head extension furthermore depends on local Arp2/3 complex-mediated actin polymerization, which is controlled by Abp1 via the Arp2/3 complex activator N-WASP. Abp1 thus plays an important role in the formation and morphology control of synapses by making a required functional connection between PSD components and postsynaptic actin dynamics. It furthermore is crucial for cytoskeletal processes underlying proper early neuronal network formation.
The Investigation of Parents' Interactions and Their Children's Learning Levels at Parental Coaching Carried out over Social Network

The study aims to provide academic and affective support for children's learning by using teacher-parent collaboration through parental coaching realized via social network. This parental coaching includes three phases: preparation, implementation and evaluation. The participants of the study are 16 parents and their children. The data of the study was obtained through the following data collection tools: family information form, focus group interview, semi-structured interviews conducted with parents and children, social network group logs, questionnaire and academic achievement scores of children. Descriptive analysis was used to analyze qualitative data and Wilcoxon t test for quantitative data. The issues which the parents ask for support are guidance for supporting their children in the courses they have problems with and help children to develop reading and study habits. The findings of the study show that parental coaching via social network increases teacher-parent, parent-parent and parent-child interaction as well as children's academic achievement. The highest amount of interaction in this application was between parents and the guidance counsellor (the researcher) and the children. The lowest level of interaction was among parents. Finally, it can be concluded that parental coaching application helped parents to support their children's learning and feel well-equipped while guiding them.
