Effect of investment in information technology system on providing desired services of accounting information system

A B ST R A C T Today, with advances in information and communication technologies and the emergence of information management system, using of these technologies in organizations is inevitable. Therefore, only managers who can invest in areas related to information technology and management system of information will be successful in enterprise management system. However, it is an important discussion that how these investments should be performed or how much it is invested? Moreover, managers must be aware of the effectiveness of using information technology and information management systems. Actually, Information Technology impacts necessary indicators for the success of today’s organization. Therefore, this study investigates the application of IT systems (IT) and management information systems (MIS) on effectiveness of these systems based on users’ view. Among the key indicators of information technology system, some indicators are selected as follows: increasing the speed of work performance, increasing accuracy of work performance, timely retrieval of information, more storage and faster access to information. In addition, the effect of these indices on providing good services in the financial reporting is investigated.
Digital Capabilities of Internet based

Advanced information and communication technologies, social media, Internet, etc. have tremendously impact on flourishing Internet based Startup around the world. Although some Internet Startups e.g. Facebook, Google, Uber, Airbnb, and Amazon are very successful, but most of the startups fail in their early stage of journey. Previous research findings show that inadequate funding, fierce competition, lack of appropriate strategies and business model, etc. are main reasons for failure of startup firms. Researchers suggest that adequate fund and proper digital business strategies can significantly support these Startups to survive and grow. Digital technologies, which include hardware, software, applications, and interactive communication technologies can significantly enhance and increase capabilities of startups through creating values and competitive advantages. Although, now days digital capabilities in large organization is getting more importance to many researchers, however a few researchers are focusing on investigating the impact of digital capabilities of Internet based startups. The study is conducted to examine how digital technologies create values for Internet based Startups Consultancy. Besides, the study investigates the digital capabilities of and how digital technologies enhance and increase the capability of Internet based Startups Consultancy firms. Five Internet based startup consultancy firms have been investigated. Case based qualitative research methodology has been followed. As research method semi-structured and informal interviews, and observation with the companies have been conducted. The study finds that Internet based digital technologies profoundly facilitate startup companies. From businesss creation to service delivery, digital technologies have enormously increase digital capabilities of internet startup firms. In addition to academic researchers, the outcome of the research will be particularly important for existing startups firms and future entrepreneurs who has plan to establish new startup.
Obesity in 7 - 10-year-old children in urban primary schools in Port Elizabeth

Objective. The primary aim of this study was to quantify the prevalence of overweight and obesity among urban 7 - 10-year-old children in affluent (quintile 5) English-medium primary schools in Port Elizabeth. Method. A quantitative, descriptive one-way cross-sectional research design utilising random sampling was used. A once-off survey consisted of anthropometrical assessment of body mass index (BMI) according to standardised procedures. To classify children into weight categories, the International Obesity Task Force z -score BMI cut-off criteria were used. Post-hoc analysis consisted of one-way analysis of variance and χ 2 tests. Level of significance was set at p <0.05. A total of 713 children participated in the study. Results. Overweight prevalence was 20.9% ( n =149) and obesity prevalence was 9.8% ( n =70). A significant interaction was found for overweight and obesity levels by gender and age ( F =7.2, p =0.01). Of the boys ( N =372) 18.5% ( n =69) were overweight and 6.9% ( n =26) were obese. The girls ( N =341) had a 23.5% ( n =80) overweight rate and 12,9% ( n =44) were obese. The highest prevalence of overweight (24.7%, n =43, N =174) was found in children aged 10, and the highest prevalence of obesity (12.5%, n =21, N =167) was found in children aged 8. Conclusion. Results highlighted the rising prevalence of overweight and obesity among urban children from economically privileged settings. Future research into paediatric obesity is needed to curb the growing incidence.

THE POPULATION GENETIC STRUCTURE OF THE MALARIA MOSQUITO ANOPHELES MELAS THROUGHOUT ITS WEST-AFRICAN RANGE A Thesis

The Population Genetic Structure of the Malaria Mosquito Anopheles melas Throughout Its West-African Range. (December 2011) Kevin Canning Deitz, B.S., State University of New York Chair of Advisory Committee: Dr. Michel A. Slotman Anopheles melas is a brackish water mosquito found along the coast of WestAfrica where it can be the dominant malaria vector locally. In order to facilitate genetic studies of this species and to examine the usefulness of microsatellite markers when used in a sibling species, 45 microsatellite loci originally developed for Anopheles gambiae were sequenced in An. melas. These loci were evaluated on their suitability as polymorphic markers based on repeat structure, length, and polymorphism in wild An. melas populations. Of the 45 loci, 18 were not considered promising markers in An. melas. A total of 48 out of 90 An. gambiae primers contained at least one mismatch with the An. melas annealing site. An. melas-specific primers were designed for 27 loci, and their variability was examined in two wild populations from Equatorial Guinea. Based on a low level of polymorphism, Hardy-Weinberg disequilibrium, or poor amplification, a further 12 loci were excluded. The remaining fifteen loci were screened in four additional wild populations from a wider geographic region including Equatorial Guinea, Cameroon, The Gambia, and Guinea Bissau. These loci showed an average heterozygosity ranging from 0.18 to 0.79, with 2.5 to 15 average alleles per locus, yielding 13 highly polymorphic markers and two loci with more limited variability in a wide geographic region. To examine the effects of cross species amplification, five of the original An. gambiae markers were also amplified in the An. melas populations. Null alleles were found for one of these An. gambiae markers. We discuss the pitfalls of using microsatellite loci even in a very closely related species, and conclude that in addition to the well-known problem of null alleles associated with this practice, many loci may
Marine biosecurity: protecting indigenous marine species

Nonindigenous species (NIS) are those that have been intentionally or unintentionally introduced outside of their native range as a consequence of human activity. If these species then threaten indigenous species and biodiversity, and/or cause economic damage, they are referred to as "invasive. " Biological invasions are not only one of the greatest threats to indigenous marine biodiversity, but they can also cause massive economic and ecological damage. Their presence could also lead to a water body failing to achieve good environmental status under the forth- coming EU Marine Strategy Framework Directive. As the rate of invasion to Great Britain and European waters continues to increase, particularly in light of climate change, the emphasis by member states is on prevention rather than on control or eradication an NIS once an invasive NIS has become established. This paper reviews NIS biosecurity planning for the marine environ- ment, including the most current legislative background, pathway identification and highlights the main issues with the current risk assessment processes. The potential impacts of marine NIS, practical biosecurity measures from Great Britain and internationally are also reviewed. The aim of this paper is to draw attention to the challenges associated with preventing the introduction of marine NIS and to highlight the urgent need for concerted action across the EU member states
Author ' s personal copy Keywords in the mental lexicon

Network science draws from a number of fields to examine complex systems using nodes to represent individuals and connections to represent relationships between individuals to form a network. This approach has been used in several areas of Psychology to illustrate the influence that the structure of a network has on processing in that system. In the present study the concept of keyplayers in a network (Borgatti, 2006) was examined in the domain of Psycholinguistics. Keyplayers are nodes in a network that, when removed, result in the network fracturing into several smaller components. A set of such nodes was found in a network of phonological word-forms as was another set of foil words, comparable to the ‘‘keywords’’ on a number of lexical and network characteristics. In three conventional psycholinguistic tasks keywords were responded to more quickly and accurately than the foils. A similar trend was observed in an analysis of the keywords and foils (and another set of foils) in the English Lexicon Project. These results open avenues for further exploration of keywords in various areas of language processing, and demonstrate the utility of the network science approach to psycholinguistics and psychology more generally. 2014 Elsevier Inc.

A frequency-coded QKD scheme with an extension to qu-quarts

We propose a novel scheme to implement the BB84 quantum key distribution (QKD) protocol in optical fibers based on a quantum frequency-translation (QFT) process. Unlike conventional QKD systems, which rely on photon polarization/phase to encode qubits, our proposal utilizes photons of different frequencies. Qubits are thus expected to reach longer propagation distances due to the photon frequency state being more robust against mechanical and/or thermal fluctuations of the transmitting medium. Finally, we put forth an extension to a security-enhanced four-character-alphabet (qu-quarts) QKD scheme.
Phytophthora species in oak forests of north-east France

Phytophthora species were surveyed from the end of 1997 through July 1998 in oak forests in NE France. Healthy (Amance) or declining (Illwald) forests were compared. The Phytophthora population in both was diverse and locally abundant. At least eight species were present at Amance and six at Illwald. At Amance Phytophthora species had a localized distribution in water and low-lying soils. At Illwald distribution was more uniform apparently due to flooding events. Most often recovered were P. citri- cola, P. gonapodyides and P. quercina. P. gonapodyides was ubiquitous in water and colonized leaf debris. P. quercina was widely distributed in soil but not abundant, and was found in sites that did not otherwise appear to favor Phytophthora. No correlation was detected between presence of Phytophthora in soil and health of trees. Unusual combinations of environmental factors may be
Search for Multi-Robot Coordination under Uncertainty

We introduce a principled method for multi-robot coordination based on a general model (termed a MacDec-POMDP) of multi-robot cooperative planning in the presence of stochasticity, uncertain sensing, and communication limitations. A new MacDec-POMDP planning algorithm is presented that searches over policies represented as finite-state controllers, rather than the previous policy tree representation. Finite-state controllers can be much more concise than trees, are much easier to interpret, and can operate over an infinite horizon. The resulting policy search algorithm requires a substantially simpler simulator that models only the outcomes of executing a given set of motor controllers, not the details of the executions themselves and can solve significantly larger problems than existing MacDecPOMDP planners. We demonstrate significant performance improvements over previous methods and show that our method can be used for actual multi-robot systems through experiments on a cooperative multi-robot bartending domain.

Running Head : POLITICAL ATTITUDES BIAS CANDIDATE ’ S FACE 1 Political Attitudes Bias the Mental Representation of a Presidential Candidate

Using a technique known as reverse correlation image classification, we demonstrate that the physical face of Mitt Romney represented in people’s minds varies as a function of their attitudes toward Mitt Romney. This provides evidence that attitudes bias how we see something as concrete and well-learned as the face of a political candidate during an election. Practically, this implies that citizens may not merely interpret political information about a candidate to fit their opinion, but that they may construct a political world where they literally see candidates differently.
Expertise, Attribution, and Ad Blocking in the World of Online Marketing

In this dissertation, we model and provide insights to some of the main challenges the world of online marketing currently faces. In the first chapter, we study the role of information asymmetry introduced by the presence of experts in online marketplaces and how it affects the strategic decisions of different parties in these markets. In the second chapter, we study the attribution problem in online advertising and examine optimal ways for advertisers to allocate their marketing budget across channels. In the third chapter, we explore the effects of modern ad blockers on users and online platforms.
Factors Affecting Revictimization in Survivors of Childhood Sexual Abuse

Structural equation modeling was used to examine how childhood sexual abuse (and other associated variables, such as family functioning and experiencing multiple forms of abuse) relates to revictimization and psychological distress. Participants were women who participated in Project HOW: Health Outcomes of Women interviews, a longitudinal study that spanned six waves of interviews. Only women with a history of childhood sexual abuse were included in the present study (n=178). Experiencing nonsexual child maltreatment in addition to childhood sexual abuse appears directly related to adult sexual and physical revictimization and indirectly related to psychological distress. Childhood sexual abuse alone was not predictive of revictimization or psychological abuse. This suggests that other mediating factors may explain the relation between CSA and revictimization found in other research. Clinical implications based on the results of the present study emphasize the importance of identifying children who have experienced multiple forms of abuse as particularly at risk for future victimization. In addition, providing interventions with a focus on education and empowerment might decrease risk for future violence and subsequent emotional maladjustment. Potential future research could examine the treatment outcomes and efficacy of these interventions as well as identify those mediating factors that increase the risk for adult revictimization for those individuals who experience only childhood sexual abuse.
CHINOSTOMA TRIVOLVIS : SUPPRESSIVE EFFECTS OF DEXAMETHASONE ON GOBLET CELL HYPERPLASIA AND WORM REJECTION IN C 3 H / HEN MICE

C3H/HeN mice were infected with Echinostoma trivolvis metacercariae on day 0, given intramuscular injections of dexamethasone daily for 5 or 7 days, and necropsied on days 5, 8, 12, 1 5, 20 and 30 p. i. Controls consisted of mice that were infected with echinostomes, but were not treated with dexamethasone. Dexamethasone treatment caused a delay in worm expulsion from the small intestine of the hosts, and the increase in goblet cell numbers that occurred in untreated mice was markedly delayed in the treated mice. Mast cell number in the small intestine increased rapidly from just after day 5 p. i. and reached a peak on day 15 p. i. in both dexamethasone-treated and control mice, although the increase in cell numbers was delayed slightly in the dexamethasone-treated mice. The eosinophi number in the small intestine of dexamethasone-treated mice was suppressed until 8 days p. i. and then increased reaching a peak on day 1 2 p. i. , although the number was about one half that of the control. As determined on day 1 2 p. i. , the mean body area of worms from dexamethasone-treated animals was significantly greater than that of the controls. Histological examination of the small intestine showed that the goblet and Paneth cell hyperplasia seen in mice infected with E. trivolvis was suppressed by dexamethosone-treatment. Transmission electron microscopy revealed no marked ultrastructural differences in the small intestine of the dexamethasone-treated and control mice except that the former had an increased number of intracristal granules in mitochondria, an increase in vesicles in the apical epithelial cells and an increase in amorphous bodies and autophagic vacuoles in the Paneth cells. These results indicate that dexamethasone treatment delayed the expulsion of E. trivolvis from the small intestine of the host mouse in association with the suppression of goblet cell hyperplasia and increase in the number of mast cells and eosinophils.
Media exposure and sponsor recall: Cricket World Cup 2003

This paper reports on a study into the relationship between media exposure and sponsor recall relating to an international event, namely the Cricket World Cup 2003 (CWC 2003). The application of sponsorship as a communication construct and recall as a media vehicle effect is investigated. Recall has been widely acknowledged as a measure of the effectiveness of a sport sponsorship. A convenience sample of university students was exposed to a self-administered questionnaire that required them to report their exposure to CWC 2003 events. Respondents were also required to list the main (global) sponsors of CWC 2003 through unaided recall. The findings indicate that there was a relationship between media exposure and sponsor recall for one sponsor, namely LG. The main conclusion is that an event sponsor has to leverage its sponsorship expenditure through the integration of other marketing communication elements to increase the recall rate. Keywords: Cricket World Cup 2003, Event sponsorship, Media exposure, Sponsor recall South African Journal for Research in Sport, Physical Education and Recreation Vol.26(2) 2004:131-140
Epidemiological coherency of vulpine dirofilariosis in environmental conditions of Slovakia

Summary Dirofilariosis belongs to zoonotic vector-borne diseases with fastest spread into new areas caused by extreme weather and seasonal changes in climate. In Slovakia, Dirofilaria spp. parasites affect more than 30 % of dogs living in endemic regions in southern parts of territory, however, data on wildlife circulation of this parasite are still scarce. In order to clarify the role of red fox (Vulpes vulpes) as the most abundant canid species in Europe in maintaining the parasite in natural foci, an initial survey of dirofilariosis in this carnivore species was conducted in Slovakia. The samples of 183 red foxes hunted in 2007 - 2009 in regions of South-Eastern and Northern Slovakia with different geographical and climate characteristics were examined by means of PCR method using specific D. repens, D. immitis and Acantocheilonema recognitum primers. The DNA was isolated from spleen samples using commercial kit and PCR approach was used for diagnostics. After amplification selected products were purified and sequenced to elucidate any homologies with previously deposited sequences in Gen Bank. The results showed 105 out of 183 examined specimens (57.4 %) being infected, with great regional differences in prevalence. Phylogenetic relationships within Dirofilaria species indicate that obtained isolates belong to D. repens. The results confirmed the role of red foxes as the reservoir of parasite. Herein, epidemiological factors that may be coherent with the Dirofilaria parasites distribution and circulation in wildlife and implications in risk assessment and prevention for domestic animals and human are discussed.
Theoretical Study of the Frustrated Ising Antiferromagnet on the Honeycomb Lattice

We study effects of the next-next-nearest-neighbour antiferromagnetic ($J_3 < 0$) interaction on critical properties (or phase diagram) of the frustrated spin-$\frac{1}{2}$ $J_1-J_2-J_3$ Ising antiferromagnet on the honeycomb lattice by using the effective-field theory with correlations. Beside the ground-state energy, we find that there is a region of $J_3 < 0$ in which the frustrated honeycomb lattice antiferromagnet exhibits a tricritical point, at which the phase transition changes from the second order to the first one on the line between N\'eel antiferromagnetic and paramagnetic phases.
