The IS effectiveness matrix: the importance of stakeholder and system in measuring IS success

The value added by an organization’s IT assets is a critical concern to both research and practice. Not surprisingly, a large number of IS effectiveness measures can be found in the IS literature. What is not clear in the literature is what measures are appropriate in a particular context. In this paper, we propose a twodimensional matrix for classifying IS effectiveness measures. The first dimension is the type of system studied. The second dimension is the stakeholder in whose interests the system is being evaluated. The matrix was tested by using it to classify IS effectiveness measures from 186 empirical papers in three major IS journals for the last nine years. The results indicate that the classifications are meaningful. This, in turn, means that the IS effectiveness matrix provides a useful guide for conceptualizing effectiveness measurement in IS research, and for choosing appropriate measures.
Beta diversity of rock‐restricted cichlid fishes in Lake Malawi: importance of environmental and spatial factors

The rock-restricted cichlid fish assemblages of Lake Malawi exhibit high spatial diversity in their species composition and relative abundance. However the extent to which this is due to the effects of local environmental differences, dispersal limitation of constituent taxa, and the assignment of allopatric populations to species is uncertain. We examined the factors associated with diversity within an assemblage from the north-western shores, encompassing a spatial scale of 170 km. For both the whole assemblage, and all constituent species-complexes, spatial variance in community structure was significantly dependent upon both geographic distances between locations and local habitat variables. Pronounced effects of distance indicate limited dispersal, but our results also show that that the spatial variance explained by geographic distance alone was strongly linked to proportion of allopatric populations within a species-complex with species status. Thus, the taxonomic status of allopatric populations underlies, at least partially, the biogeographical structure of this assemblage. Substrate composition and habitat depth were also significant determinants of community structure, although spatial variance attributed to these variables was less than that associated with distance alone. Substantial unexplained variance may be a consequence of the effects of unmeasured habitat variables, high ecological similarity between co-occurring species, stochastic influences on population abundance, and the effects of local adaptation. Despite low spatial variance explained by the assessed environmental variables, significant environmental influence on cichlid assemblage structure across a wide spatial scale indicates that even slight future environmental changes may have the capacity to significantly alter species composition.
A low cost hand-eye calibration method for arc welding robots

Hand-eye calibration is one of the most important and fundamental tasks in performing visual guided robot control tasks. Many techniques have been proposed that use various expensive equipment ranging from a three dimensional positioning device to a laser measurement device. The work presented in this paper aims at developing a low cost robot hand/eye calibration method that is accurate and robust enough to be used in a robotic arc welding system. The proposed calibration method allows the camera and object frames to be referenced directly to the robots base co-ordinate frame. Experimental results show that the developed method can be used to achieve a calibration accuracy of 1 mm (in the directions of interest, X and Y axes) that is acceptable for robotic welding applications.
Knowledge-lite extraction of multi-word units with language filters and entropy thresholds

In this paper two approaches to knowledge-lite terminology extraction are compared, both involving language filters which are used to remove ill-formed multi-word units (MWUs). A knowledge-lite approach entails swift portability to new languages and to new domains, which is difficult to achieve if knowledge-intensive resources such as grammars, parsers, taggers and lexicons are used. The two approaches described in this paper have been applied in monolingual term extraction for translation purposes as well as in a pre-processing stage for bilingual word and MWU alignment. The implemented software has been tested for Swedish, English, German and French.
An evaluation on the attitudes of residents in georgetown towards the impacts of tourism development

The study confirms the usefulness of social exchange theory in explaining residents’ perception toward tourism development in Georgetown. There are positive and significant relationship between personal benefit gained from tourism development, perceived positive impacts and support for tourism development. Nevertheless, only one finding which is not in aligned with social exchange theory. There is no significant relationship for perceived negative impact towards support for additional tourism development. In short, residents who benefit from tourism development in Georgetown perceived greater positive impact than those who receive less benefit or do not receive any benefit. The positive impact that resident perceived has a positive relationship with their support level toward tourism development. Keyword: Tourism development, social exchange theory, Georgetown, Malaysia, attitudes.
From Retreat Center to Clinic to Boardroom? Perils and Promises of the Modern Mindfulness Movement

From its venerable Buddhist roots, mindfulness training (MT) has spread rapidly across the globe in the past few decades due to its strong salutary claim, i.e., the notion that meditation practice is an efficacious means for self-improvement. However, concerns have arisen that the appropriation of MT techniques from classical Buddhist tradition into modern secular practice has diluted the benefits of these practices. The “great danger” to the movement is that inadequately adapted MT techniques, combined with unreasonable inflation of expectations regarding MT’s benefits, may undermine MT’s true potential to effect positive change in the world. And yet, these concerns can be mitigated by consideration of the salutary claim as a persistent “quality check” on MT efficacy. It is argued that scientific investigation can take an important role in delineating the necessary characteristics for fulfilling mindfulness’ salutary claim, as well as identifying contraindicated techniques and risk factors for training. By accepting that we cannot control the spread of MT into commercial domains, researchers may still work to distinguish “right” from “wrong” mindfulness through empirical study. In this way, modern science may help to realize the salutary claim and even contribute to classical Buddhist conceptions of mindfulness, advancing our understanding of how best to promote well-being.
Understanding How Western-Trained Music Therapists Incorporate Chinese Culture In Their Practice In China: An Ethnographic Study

Although music therapists work with Chinese people in the United States, Canada, Australia, and China, little is known about how these music therapists incorporate Chinese culture in their practice in order to provide culturally-responsive music therapy. This ethnographic research study aimed to understand how Western-trained music therapists incorporated Chinese culture in their practice in China. The researcher observed music therapy sessions of two Western-trained music therapists in a neurologic rehabilitation and mental rehabilitation department in a hospital in China. The two music therapists, two of their clients, and two facility professionals were interviewed. Six categories were identified in the analysis. The findings indicated that Western-trained music therapists incorporated Chinese culture in their session by: using “mixture” music, developing and maintaining guanxi with various individuals, using multiple models of music therapy, using a variety of active and receptive experiences, using the Chinese Mandarin language, and acknowledging that music therapy is a natural therapy. Overall, themes of mixture were in several of the categories suggesting that music therapy with Chinese people is a “mixture” music therapy. Future research by Chinese music therapists is needed to understand varying perspectives of culturally-responsive music therapy for Chinese people.
Wavelet: a new tool for business cycle analysis

One basic problem in business-cycle studies is how to deal with nonstationary time series. The market economy is an evolutionary system. Economic time series therefore contain stochastic components that are necessarily time dependent. Traditional methods of business cycle analysis, such as the correlation analysis and the spectral analysis, cannot capture such historical information because they do not take the time-varying characteristics of the business cycles into consideration. In this paper, we introduce and apply a new technique to the studies of the business cycle: the wavelet-based time-frequency analysis that has recently been developed in the field of signal processing. This new method allows us to characterize and understand not only the timing of shocks that trigger the business cycle, but also situations where the frequency of the business cycle shifts in time. Our empirical analyses show that 1973 marks a new era for the evolution of the business cycle.
Schema recognition using modified weighted direction index histogram for medical document retrieval systems

This paper discusses a schema recognition method considering annotations to improve recognition accuracy of the previous method. Previously, we studied document image recognition methods for medical/clinical documents and their applications. In addition, we also discussed the method to recognize schemas in the document, because they had important key information for medical document retrieval. However, annotations made a feature vector change drastically, as a result, reduction of the recognition accuracy was caused. In this paper, annotations were automatically detected, and the feature vectorconsidering them was generated. We conducted evaluation experiments using actual schemas used in Mie University Hospital. After experiments, the recognition accuracy of the proposed method was 96%.
A Hybrid Distance-Based Ideal-Seeking Consensus Ranking Model

Ordinal consensus ranking problems have received much attention in the management science literature. A problem arises in situations where a group of k decision makers (DMs) is asked to rank order n alternatives. The question is how to combine the DM rankings into one consensus ranking. Several different approaches have been suggested to aggregate DM responses into a compromise or consensus ranking; however, the similarity of consensus rankings generated by the different algorithms is largely unknown. In this paper, we propose a new hybrid distance-based ideal-seeking consensus ranking model (DCM). The proposed hybrid model combines parts of the two commonly used consensus ranking techniques of Beck and Lin (1983) and Cook and Kress (1985) into an intuitive and computationally simple model. We illustrate our method and then run a Monte Carlo simulation across a range of k and n to compare the similarity of the consensus rankings generated by our method with the best-known method of Borda and Kendall (Kendall 1962) and the two methods proposed by Beck and Lin (1983) and Cook and Kress (1985). DCM and Beck and Lin's method yielded the most similar consensus rankings, whereas the Cook-Kress method and the Borda-Kendall method yielded the least similar consensus rankings.
Examining the Role of Usability, Compatibility and Social Influence in Mobile Banking Adoption in Indonesia

Adaptation to the internet and advances in mobile technology has become key to the survival of industries, including the banking industry. One of the latest electronic banking channels is mobile banking. While mobile banking offers various advantages, many banks in Indonesia are facing the problem of low adoption. This paper reports on the findings of our research project, which examines mobile banking adoption behavior in Indonesia from an interaction perspective. Specifically, the paper examines the role of usability, compatibility and social influence in explaining people’s intention to continue using mobile banking in Indonesia. Using an interaction perspective framework, a research model is proposed. Ten hypotheses are suggested, examining six constructs: satisfaction, perceived usefulness, perceived ease of use, perceived learnability, compatibility and social influence. From a theoretical perspective, this paper is the first to combine usability, compatibility and social influence in a mobile banking adoption study. Data from 319 valid respondents were used to test the proposed model using partial least squares structural equation modeling. The results show that all the hypotheses are supported, and it was found that people’s intention to continue using mobile banking is significantly affected by satisfaction, compatibility, perceived usefulness, perceived learnability and social influence.
HDR endobronchial brachytherapy in palliative and combined radical treatment of lung cancer

In patients with advanced or metastatic lung cancer who present predominantly with dyspnoea and haemoptysis the use of HDR brachytherapy has been proven an effective method of palliation. The application of brachytherapy as a boost to EBRT in curative cases is much more restricted. It can be considered in a selected group of patients with dominating endobronchial disease, who are medically inoperable, or have small or occult carcinomas of the lung.
From Endomorphisms to Automorphisms and Back: Dilations and Full Corners

When S is a discrete subsemigroup of a discrete group G such that G = S−1S, it is possible to extend circle‐valued multipliers from S to G, to dilate (projective) isometric representations of S to (projective) unitary representations of G, and to dilate/extend actions of S by injective endomorphisms of a C*‐algebra to actions of G by automorphisms of a larger C*‐algebra. These dilations are unique provided they satisfy a minimality condition. The (twisted) semigroup crossed product corresponding to an action of S is isomorphic to a full corner in the (twisted) crossed product by the dilated action of G. This shows that crossed products by semigroup actions are Morita equivalent to crossed products by group actions, making powerful tools available to study their ideal structure and representation theory. The dilation of the system giving the Bost–Connes Hecke C*‐algebra from number theory is constructed explicitly as an application: it is the crossed product C0(Af)⋊Q*+, corresponding to the multiplicative action of the positive rationals on the additive group Af of finite adeles.
Teacher Opinions Based Evaluation of Problems in Turkish Instruction to Syrians.

The purpose of this study is to evaluate the problems of Turkish instruction offered to the Syrians in line with teacher opinions. A semi-structured interview form developed by the researchers has been utilized in order to determine the opinions of teachers, managers and assistant personnel engaged in teaching Turkish to the Syrians related to the issues arising from the teaching environment and the teaching equipment and materials within the extent of the research carried out in form of a case study from the qualitative research methods. The working group of study has been formed by 40 teachers determined according to the method of easy-to-reach situation and principle of voluntary participation. As a result of this research formed within the framework of teacher opinions, it has been found out that the most serious educator – originated problem in the teaching Turkish language to the Syrians was the educational perception distinction between Syrian and Turkish teachers and that the students are prejudiced against Turkish language and they did not have any need to learn Turkish and the administrators have precluded in-class activities and the auxiliary staff has exhibited inappropriate behaviors and there were serious deficiencies in the learning environment and that the materials prepared to teach Turkish to Syrians were inadequate and not matching with its intended objective.

Improved eIF4E Binding Peptides by Phage Display Guided Design: Plasticity of Interacting Surfaces Yield Collective Effects

Eukaryotic initiation factor (eIF)4E is over-expressed in many types of cancer such as breast, head and neck, and lung. A consequence of increased levels of eIF4E is the preferential translation of pro-tumorigenic proteins (e.g. c-Myc and vascular endothelial growth factor) and as a result is regarded as a potential therapeutic target. In this work a novel phage display peptide has been isolated against eIF4E. From the phage sequence two amino acids were delineated which improved binding when substituted into the eIF4G1 sequence. Neither of these substitutions were involved in direct interactions with eIF4E and acted either via optimization of the helical capping motif or restricting the conformational flexibility of the peptide. In contrast, substitutions of the remaining phage derived amino acids into the eIF4G1 sequence disrupted binding of the peptide to eIF4E. Interestingly when some of these disruptive substitutions were combined with key mutations from the phage peptide, they lead to improved affinities. Atomistic computer simulations revealed that the phage and the eIF4G1 derivative peptide sequences differ subtly in their interaction sites on eIF4E. This raises the issue, especially in the context of planar interaction sites such as those exhibited by eIF4E, that given the intricate plasticity of protein surfaces, the construction of structure-activity relationships should account for the possibility of significant movement in the spatial positioning of the peptide binding interface, including significant librational motions of the peptide.
A Measurement of the Electromagnetic Luminosity of a Kerr Black Hole

Some active galactic nuclei, microquasars, and gamma-ray bursts may be powered by the electromagnetic braking of a rapidly rotating black hole. We investigate this possibility via axisymmetric numerical simulations of a black hole surrounded by a magnetized plasma. The plasma is described by the equations of general relativistic magnetohydrodynamics, and the effects of radiation are neglected. The evolution is followed for 2000GM/c3, and the computational domain extends from inside the event horizon to typically 40GM/c2. We compare our results to two analytic steady state models, including the force-free magnetosphere of Blandford & Znajek. Along the way we present a self-contained rederivation of the Blandford-Znajek model in Kerr-Schild (horizon penetrating) coordinates. We find that (1) low-density polar regions of the numerical models agree well with the Blandford-Znajek model, (2) many of our models have an outward Poynting flux on the horizon in the Kerr-Schild frame, (3) none of our models have a net outward energy flux on the horizon, and (4) one of our models, in which the initial disk has net magnetic flux, shows a net outward angular momentum flux on the horizon. We conclude with a discussion of the limitations of our model, astrophysical implications, and problems to be addressed by future numerical experiments.
A socio-spatial dimension of career choices in veterinary education

ABSTRACT In this article we report the outcomes of a study on career choices of rural veterinary students during the educational process. In accordance with social representations theory, we studied how the representational project that students build during their curriculum is influenced by the socio-spatial elements of their biography (including childhood and work locations). To do this we designed a quantitative survey (N = 1508) using an approach incorporating multiple methodologies. Our results highlight a network organisation of rural veterinarian job representation with a socio-spatial dimension of rural areas. We recommend that career guidance counsellors take into account the socio-spatial dimension of the life course in order to help students with their professional choices.
Prevalence of iron deficiency anemia in Iranian children under 6 years of age: a systematic review and meta-analysis

Background: Iron deficiency anemia is a prevalent condition among children in developing and developed countries that leads to impaired development, activity intolerance, behavioral changes, irritability, and reduced learning ability. The studies conducted in Iran have reported different prevalence rates for this condition. This systematic review and meta-analysis were aimed at estimating the prevalence of iron deficiency anemia in Iranian children under 6 years of age. Methodology: Persian and English articles published from 2001 to 2018 were collected. The search process was conducted in national and internationals databases, including SID, MagIran, PubMed, Scopus, and Web of Science, using the following keywords and their combinations: Iron, Iron deficiency, Iron deficiency anemia, Ferritin, Child, Children, and Iran. The data were analyzed using the meta-analysis and random effects model. Heterogeneity was assessed using the I2 statistic. All analyses were performed using the STATA software, version 12. Results: Analysis of six selected articles with a total sample size of 1,700 showed that the prevalence rates of iron deficiency and iron deficiency anemia in the Iranian children under 6 years of age were 27.7% (95% CI: 11.9–43.5) and 18.2% (95% CI: 14.3–22), respectively. In addition, the prevalence of iron deficiency anemia was higher in boys (17.7% with 95% CI: 5.9–29.5) than in girls (14.4% with 95% CI: 4.5–24.2). Conclusion: About one-fifth of Iranian children under the age of 6 years suffer from iron deficiency anemia. Identification of those at risk of developing this condition with the goal of prevention, diagnosis, and treatment seems to be an important and necessary task.
Neural network based feedback error controller for helicopter

Purpose – This paper seeks to present a feedback error learning neuro‐controller for an unstable research helicopter.Design/methodology/approach – Three neural‐aided flight controllers are designed to satisfy the ADS‐33 handling qualities specifications in pitch, roll and yaw axes. The proposed controller scheme is based on feedback error learning strategy in which the outer loop neural controller enhances the inner loop conventional controller by compensating for unknown non‐linearity and parameter uncertainties. The basic building block of the neuro‐controller is a nonlinear auto regressive exogenous (NARX) input neural network. For each neural controller, the parameter update rule is derived using Lyapunov‐like synthesis. An offline finite time training is used to provide asymptotic stability and on‐line learning strategy is employed to handle parameter uncertainty and nonlinearity.Findings – The theoretical results are validated using simulation studies based on a nonlinear six degree‐of‐freedom helic.
