Assessing and analyzing customers’ value-in-useto improve a supplier’s value offering in abusiness-to-business knowledge intensivebusiness services context : an exploratory study

Nowadays, the service business-to-business (B2B) environment is changing rapidly. The effects of, for example, increasing globalization and digitalization increase the level of competition among suppliers. As a result, allowing customers to optimize value creation becomes a key factor to obtain competitive advantage in B2B markets. In the academic world, value-in-use is increasingly employed to analyze customer value. However, research about understanding customer value through the lens of value-in-use is still very limited. In this research paper, the value-in-use of customers in a B2B knowledge intensive business services (KIBS) market is explored through semi-structured interviews. In total, 23 dimensions of value-in-use are identified across four stages of the customer service consumption process. Understanding customer value is increasingly important for B2B suppliers, because B2B customers will increasingly base their buying decisions on value creation instead of price in the future. However, no two customers are precisely alike and thus have unique demands. Surprisingly, few studies have empirically addressed differences in customer value. Therefore, the differences in customers’ value-in-use are examined to discover if customers differ significantly in what they value. The results show that the analyzed KIBS market, the professional development training market, is extremely fragmented in terms of what customers value. Another important finding is that customers in the professional development training market demand a different value-in-use based on personal characteristics and the characteristics of a professional development training course. An implication for professional development training providers is that employing tailored approaches based on, for example, geographical customer segments is no longer valid due to customer heterogeneity. To optimize the potential value creation of customers, professional development training providers are forced to employ a single flexible market approach. A flexible market approach is a partly standardized approach, but flexible enough to meet the needs of each specific customer.
Sound Pressure Levels in Churches in Port Harcourt: A Study of Some Catholic, Anglican and Pentecostal

Churches represent an excellent environment in the propagation of sound which poses a high risk in the occurrence of noise induced hearing loss. According to the Nigerian National environmental standard and regulation Act 2007, the maximum permissible noise level in worship centers should not exceed 75dB and considering Nigeria to have the highest rate of church proliferation in the world makes it imperative to do this study. The aim of this study is to determine the level of sound exposure to church worshippers in Port Harcourt. Methodology: A prospective, cross sectional study involving 30 churches (10 selected from catholic, Anglican and Pentecostal churches), selected by simple random sampling from Port Harcourt metropolis carried out between January to June 2015. Sound pressure level meter was used to measure the sound levels in churches. Data was collected and analyzed using SPSS 20. Results: Thirty (30) churches participated in the study. The duration of service/mass was between 2-7 hours with a mean of 3.03 hours. The average SPL measurement was highest in Pentecostal churches (98.4 ± 3.1dB), followed by catholic churches (96.3 ± 6.8 dB), and the least Anglican churches (87.6 ± 1.3 dB). All the catholic churches, 50 % of Anglican and 60 % of Pentecostal churches were purpose built, but none was acoustically designed. Conclusion: The SPLs reported in the churches are higher than the safety permissible limits of sound, thus making it unacceptable, illegal and punishable. There should be increased advocacy and implementation of the noise regulation laws in Nigeria in order to reduce the risk of noise induced hearing loss.
Exploring forest infrastructures equipment through multivariate analysis: complementarities, gaps and overlaps in the Mediterranean basin

The countries of the Mediterranean basin face several challenges regarding the sustainability of forest ecosystems and the delivery of crucial goods and services that they provide in a context of rapid global changes. Advancing scientific knowledge and foresting innovation is essential to ensure the sustainable management of Mediterranean forests and maximize the potential role of their unique goods and services in building a knowledge-based bioeconomy in the region. In this context, the European project FORESTERRA ("Enhancing FOrest RESearch in the MediTERRAnean through improved coordination and integration”) aims at reinforcing the scientific cooperation on Mediterranean forests through an ambitious transnational framework in order to reduce the existing research fragmentation and maximize the effectiveness of forest research activities. Within the FORESTERRA project framework, this work analyzed the infrastructures equipment of the Mediterranean countries belonging to the project Consortium. According to the European Commission, research infrastructures are facilities, resources and services that are used by the scientific communities to conduct research and foster innovation. To the best of our knowledge, the equipment and availability of infrastructures, in terms of experimental sites, research facilities and databases, have only rarely been explored. The aim of this paper was hence to identify complementarities, gaps and overlaps among the different forest research institutes in order to create a scientific network, optimize the resources and trigger collaborations.
Social competence and social-emotional isolation and eating disorder psychopathology in female and male adolescent psychiatric inpatients 1

The ex post facto study examined the association between interpersonal deficits in peer relations and specific aspects of eating disorder (ED) psychopathology in psychiatrically-hospitalized adolescent girls and boys. Four hundred and ninety-two psychiatric inpatients (286 girls and 206 boys), aged 12 to 19 years, completed selfreport instruments that generate assessments of peer relations, ED psychopathology, self-esteem, and depression. Associations between peer and ED variables were examined separately by sex and after controlling for levels of self-esteem and depression. Among males and females social-emotional isolation was positively related to body image dissatisfaction and binge eating both prior to and after controlling for low self-esteem and depressed mood. Among males, but not females, less social competence was related to greater body image dissatisfaction both prior to and after controlling for low selfesteem and depressed mood, and to dietary restriction prior to controlling for low selfesteem and depressed mood. Interpersonal deficits in peer relations are associated with ED psychopathology in both female and male adolescents even after accounting for depression and low self-esteem. Excluding males from research in this area may be problematic as relative to adolescent girls, adolescent boys’ experiences with peers may be particularly impacted by ED-related psychopathology.
Antimicrobial Activity of Vigna unguiculata L. Walp Seed Oil

The antimicrobial activity of three varieties of Vigna unguiculata L. Walp seed oil (LBS-1, LBS-2 and LBS-3) were investigated against five Gram positive bacteria ( Bacillus megaterium, Bacillus subtilis, Sarcina lutea, Salmonella typhi and Staphylococcus aureus ) and four Gram negative ( Escherichia coli, Shigella dysenteriae, Shigella sonnei, Shigella shiga ) and four fungi ( Penicilium spp., Mucor spp., Candida albicans and Aspergillus fumigatius ). The LBS-1 oil at the concentration of 400 I¼g/ disc showed the highest activity against Sarcina lutea (19Â±0.1 mm) than that of LBS-2 (14Â±0.3 mm) and LBS-3 (12Â±0.3 mm) oil whereas LBS-3 oil showed highest activity against Staphylococcus aureus (16Â±0.1 mm) than that of LBS-1 (10Â±0.6 mm) and LBS-2 (13Â±0.4 mm) oil. All the three oils are active against the three tested fungi namely Penicilium spp. , Mucor spp. and Candida albicans but showed no sensitivity against Aspergillus fumigatius .

Social networks influence various aspects of both material life and spiritual life. The social relationships are clearly demonstrated in the labour market. Many domestic and international researches show that social network is an effective unofficial channel for job search. The study of the 2015 and 2016 Sociology graduates from Vietnam National University, Hanoi (VNU) University of Social Sciences and Humanities provides a profound understanding of the role of social networks in the graduates’ job search and their professional development.

Stimulated and spontaneous four-wave mixing in silicon-on-insulator coupled photonic wire nano-cavities

We report on four-wave mixing in coupled photonic crystal nano-cavities on a silicon-on-insulator platform. Three photonic wire cavities are side-coupled to obtain three modes equally separated in energy. The structure is designed to be self-filtering, and we show that the pump is rejected by almost two orders of magnitude. We study both the stimulated and the spontaneous four-wave mixing processes: owing to the small modal volume, we find that signal and idler photons are generated with a hundred-fold increase in efficiency as compared to silicon micro-ring resonators.
Environmental Information Provision as a Public Policy Instrument

Abstract We examine information provision as a public policy instrument when products generate damages to consumers as well as environmental externalities. We show that information provision dominates taxation in terms of welfare, if information can be provided at low cost. This is because a uniform tax alone levies a heavier than optimal burden on informed consumers and allows the uninformed consumer to free ride partially on the informed consumers’ voluntary actions. If the cost of information provision is substantial, taxation is welfare superior. A policy regime that combines information provision and taxation leads to higher welfare relative to the use of either instrument alone.
Image based retrieval of concrete crack properties

Purpose This paper presents a new method to retrieve concrete crack properties based on image processing techniques. Method Detection and quantification of cracks in concrete bridges pose various challenges. Cracks have fewer pixels compared to their background. For effective visualization, the objects need to be captured from near field. But it is not always possible to capture the complete cracked surface in a single frame while taking the image from near field. Hence image stitching is required before pre-processing of images for further analysis. Usually retrieved images have low contrast due to environmental and equipment limitations which add another difficulty in image visualization. State-ofthe-art image pre-processing as suggested in the literature may not be suitable for images captured in different environmental conditions. This paper discusses various techniques for image enhancement using point processing, histogram equalization and mask processing. Furthermore, a binary image is required to obtain a skeleton of an object. However, the pre-processing techniques cause discontinuity in crack alignment. Morphological techniques (e.g. dilation) are used in this work through successive iteration to ensure connectivity. Then the object skeleton which is unaffected by expanded boundaries is obtained by using skeleton algorithm to retrieve concrete crack properties such as length, bounding rectangle, and major and minor principal axes lengths. Results & Discussion The preliminary results obtained using this methodology is capable of retrieving length, orientation and bounding box of the identified cracks. This method is aimed at assisting in obtaining automated prediction of condition state (CS) rating of cracks in bridges. It can be also used as a tool for post-earthquake damage evaluation purposes.
Are Traditional Motivation Theories Used in Face-to-Face Classes Valid in an E-learning Environment?

This research aims to develop an elementary school English e-learning system based on the ‘Self-determination theory (SDT)’, which is widely applied to traditional face-to-face foreign language classes. The study also attempts to verify whether SDT? a traditional motivational theory that has been applied to face-to-face classes? is effective in an e-Learning environment with students who use this newly developed system. For the purposes of this project, the following three actions were carried out. First, a motivational strategy based on SDT was deduced. In SDT, the needs for autonomy, competence, and relatedness were introduced as basic psychological needs, and assumed that these three needs provided the natural motivation for learning, growth, and development. Second, an e-Learning system was created based on the deduced motivational strategy. Third, the system was implemented in 115 private tuition academies, and education was provided to 1,400 users for one year across the country. Afterwards, by surveying users, correlation between the role of the three psychological needs in learning English, and also the correlation between each need and motivation were investigated. Research results showed that traditional motivational theories used in face-to-face classes so far were effective in an e-Learning environment.
Monolayer Doping via Phosphonic Acid Grafting on Silicon: Microscopic Insight from Infrared Spectroscopy and Density Functional Theory Calculations

Monolayer doping (MLD) is a promising technique for creating ultra shallow junctions (USJs). Here, a novel self assembled monolayer (SAM) grafting technique is proposed through a single oxygen atom capable of MLD. Consequently, this approach can use simple forms of alkylphosphonic acids and avoid carbon contamination altogether during the doping process. In this paper, density functional theory (DFT) is used to explore the way how alkylphosphonic acid molecules can in just one chemical step be grafted on H‐terminated Si(111). A maximum coverage of alkylphosphonic acids is found at 2/3 due to steric constrain forces. It is further demonstrated by means of in situ infrared spectroscopy and DFT calculations that the weak link of an alkylphosphonic acid, such as octadecylphosphonic acid (ODPA), is the P‐C bond, with typical release of the carbon ligand around 500 °C. Finally, after release of the carbon ligand, an unsaturated electron configuration is driving force for the phosphorous to start the MLD process.
Formulating Generalize Malware Attack Pattern Using Features Selection

Number of malware is growing dramatically. Malicious codes can be easily obtained and use as one of weapon to gain illegal objectives. Hence, in this project, network traffic are explored to identify the traces left on the victim and attacker to reveal the true victim and attacker. For the purpose of this project, it focused on malware intrusion and traditional worms namely Blaster and Sasser worm variants. This project is operated based on victim’s and attacker’s perspective. Thus, the objective of this project is to identify the features/attributes of malware in perspective of victim and attacker, to generate attack pattern of malware in perspective of victim and attacker, and to generalize the attack pattern in perspective of victim and attacker. Based on generating the attack pattern, the attack pattern for malware is generalized in algorithm script to verify it accuracy.
A Fundamental Evaluation of the Municipal Solid Waste Management in Ado Ekiti, Nigeria, Using the Rating Index of the Users and Operatives

The assessment of the management of the municipal solid waste (MSW) in Ado Ekiti being undertaken by Ekiti State Waste Management Board (ESWMB) was done using questionnaires distributed randomly to the users and government operatives of the service. The questionnaire responses were on a five-point scale, similar to the Likert’s scale, but not bipolar. The data was collected from the users of the main dumpsters, which are located at Opopogboro, Ajilosun, Atikonkon, Oja Oba and Odo Ado areas of the city. Also, the data from the operatives was collected from the driver and four labourers designated to collect waste from each dumpster. The people’s rating index (PRI), which was calculated from the weighted value of the responses to different questions, was used to determine the overall index value whose maximum value is 100. The rating was classified into five categories- bad, fair, fairly good, good, very good and excellent, to enable pragmatic assessment of each issue being assessed. The rating of the users varies from fair to fairly good while the rating of the operatives varies from fair to very good. The general better rating of the operatives compared to the users indicate the reason the state government is oblivious of the poor status of the management of the municipal solid waste (MSW) in Ado Ekiti. The findings in this study suggest that the state government needs to hold a stakeholders summit on effective management of MSW in Ado Ekiti. With this, critical issues relating to urgent need for improvement and increased funding from non-governmental organisations and the federal government will be resolved. In conclusion, the approach used in this study, which is not symmetrical and includes the perception of primary stakeholders appears to be pragmatic and suitable for foundational appraisal of the management of a basic MSW system.
Bowling ball representations of braid groups

In a remark in his seminal 1987 paper, Jones describes a way to define the Burau matrix of a positive braid using a metaphor of bowling a ball down a bowling alley with braided lanes. We extend this definition to allow multiple bowling balls to be bowled simultaneously. We obtain the Iwahori-Hecke algebra and a cabled version of the Temperley-Lieb representation.
Perturbation Experiments in Community Plant Species during Recovery from Agricultural Abandonment in a Semi-Arid Region of Central-Western Spain

Background: Can high diversity mixtures of later succession plant species be able to suppress early successional (arable weed) species than low diversity species mixtures? Can the removal of plant functional groups have important consequences on the sys-tem stability? Location: The study area was located at 850 m a.s. l. , fifteen kilometers (15 km) to the west of Salamanca city, Spain, in a dehesa-like woodland. Methods: The field experiment was installed in Spring 1996 (May). The plots represented former agricultural lands cropped with (a rotation of) monocultures and abandoned right at the beginning of the experiment after the last crop was harvested in 1995. Before in-stalling plots, the fields were harrowed and equalized. The treatments (NC-natural colonization, LD-low diversity seed mixture and HD-high diversity seed mixture) were randomly allocated to the plots in each block. The experiment was organised accord-ing to a block design with five replicate blocks. Within each block, four plots measur-ing 10 × 10 m were marked out and each of the three treatments was randomly as-signed to one plot. All plots were separated by 2 m walkways. Results: The competitive ability of the sown species in different mixtures in LD, valued on the basis of their performance in HD, is a good predictor of their ability to suppress the weed crops spe-cies. This was also corroborated by the high relationship between the efficiency of the sown species in both treatments of species mixture (R2 = 0.51, F (1, 33) = 34.56, P < 0.001). Conclusions: The increase of colonizing species cover was significantly lower in LD, which again supported the increase of biomass in 1998, being also lower in HD. Therefore, this increase in the community is more prominent in LD treatments. The effect of sown species was not so important in this increase.
On the Factors Affecting the Accuracy and Robustness of Smoothed-Radial Point Interpolation Method

In order to overcome the possible singularity associated with the Point Interpolation Method (PIM), the Radial Point Interpolation Method (RPIM) was proposed by G. R. Liu. Radial basis functions (RBF) was used in RPIM as basis functions for interpolation. All these radial basis functions include shape parameters. The choice of these shape parameters has been and stays a problematic theme in RBF approximation and interpolation theory. The object of this study is to contribute to the analysis of how these shape parameters affect the accuracy of the radial PIM. The RPIM is studied based on the global Galerkin weak form performed using two integration technics: classical Gaussian integration and the strain smoothing integration scheme. The numerical performance of this method is tested on their behavior on curve fitting, and on three elastic mechanical problems with regular or irregular nodes distributions. A range of recommended shape parameters is obtained from the analysis of different error indexes and also the condition number of the matrix system. All resulting RPIM methods perform very well in term of numerical computation. The Smoothed Radial Point Interpolation Method (SRPIM) shows a higher accuracy, especially in a situation of distorted node scheme.
The Efficiency of the Friedman Rule in a Monetary Union

This paper evaluates the performance of the Friedman rule and characterizes efficient allocation of resources within a new-generation, search-theoretic model of monetary union with divisibility and degenerate distribution of money holdings. The main results are: i) the Friedman rule is a necessary and sufficient condition for global efficiency, and ii) the Friedman rule is necessary for local efficiency, as it is the unique policy rule that eliminates the hold-up problem in any local market. It is also shown that the efficient quantity demanded by a country-i buyer is increasing, and the country-i price of goods is decreasing, in the country-i fraction of sellers.
