The scientific building blocks for business coaching: A literature review

Orientation: Business coaching is a relatively new approach to leadership development. It is also slowly growing as an academic discipline with only a small number of active researchers and a dearth of published literature reviews. Research purpose: This article is an investigation into the current level of development of the body of knowledge related to business coaching by means of a systematic literature review. Motivation of the study: Previous literature reviews summarised the available published articles. In order to contribute to establishing business coaching as an independent academic discipline, the building blocks for science in the phenomenon under investigation have to be scientifically not only summarised, but also synthesised and explored to ground this new discipline as an academic field of research. Research design, approach and method: A methodological framework has been developed to analyse the information. The data were synthesised according to the following building blocks for science: concepts, definitions, typologies, models, theories and paradigms. Main findings: A total of 84 articles were accessed by the specified search strategy and 36 were analysed according to inclusive and exclusive criteria. Although coaching has not been sufficiently developed as an academic discipline, it is possible to develop a comprehensive definition of coaching, as well as to identify the main models and theories that apply to this field. Practical/managerial implications: This literature review has synthesised and summarised the available data in such a way that it will contribute to the conceptualisation and foundation of business coaching as an academic discipline. Contribution: The building blocks for business coaching as a relatively new and emerging science within the field of business leadership have been defined. This will contribute to the articulation of concepts within this discipline by future researchers and practitioners.
KELT-18b: Puffy Planet, Hot Host, Probably Perturbed

We report the discovery of KELT-18b, a transiting hot Jupiter in a 2.87-day orbit around the bright (V = 10.1), hot, F4V star BD+60 1538 (TYC 3865-1173-1). We present follow-up photometry, spectroscopy, and adaptive optics imaging that allow a detailed characterization of the system. Our preferred model fits yield a host stellar temperature of K and a mass of , situating it as one of only a handful of known transiting planets with hosts that are as hot, massive, and bright. The planet has a mass of , a radius of , and a density of , making it one of the most inflated planets known around a hot star. We argue that KELT-18b’s high temperature and low surface gravity, which yield an estimated ∼600 km atmospheric scale height, combined with its hot, bright host, make it an excellent candidate for observations aimed at atmospheric characterization. We also present evidence for a bound stellar companion at a projected separation of ∼1100 au, and speculate that it may have contributed to the strong misalignment we suspect between KELT-18's spin axis and its planet’s orbital axis. The inferior conjunction time is 2457542.524998 ± 0.000416 (BJDTDB) and the orbital period is 2.8717510 ± 0.0000029 days. We encourage Rossiter–McLaughlin measurements in the near future to confirm the suspected spin–orbit misalignment of this system.
Designing a management information system to support business school accreditation status

Oulu Business School required a management information system which would reduce the manual work requirements for AACSB reports and improve the overall data collection process. By employing design science research, it was possible to construct a detailed analysis of the requirements of Oulu Business School and model these into a set of objectives for the system. These requirements were extrapolated further, using Agile methodology, into a concise list of user stories which would form the backbone of the development process. To meet the needs of both the faculty and AACSB accreditation, Oulu Business School wanted to replace their current data collection process with a web-based information system. This system that would collect contribution information from all staff members and generate a variety of reports from the data collected on-demand. Although there was a pre-existing system, it was not considered fit for purpose. Therefore, the project started from nothing. This allowed the team to gather concise requirements as well as using previously unused methodologies. To this end, we focused on using Design Science Research as this the study of how an information system behaves dependent on its overall purpose. In the main, the motivation for this research was the need to improve its data collection and information processing methods of the Oulu Business School. By employing a combination of Agile development methodologies and design science methodologies, it was possible to build a very clear concept of what was to be developed and how. Design science provided the foundational knowledge required to define the nature of the system while Agile provided the tools for creating the artefact in an efficient and effective manner. The artefact was created over a 5-month development period with 10 sprints, or iterations, in total. Overall, the project managed to achieve the majority of the goals that were set and produced a fully-fledged system which has entered full use by the Oulu Business School. Additionally, the success of the system has been such that Oulu Business School has continued developing OBSIC and is considering the possibility of offering the system to other accredited schools.
PROSPECTS FOR JOINT GRAVITATIONAL WAVE AND SHORT GAMMA-RAY BURST OBSERVATIONS

We present a detailed evaluation of the expected rate of joint gravitational-wave (GW) and short gamma-ray burst (GRB) observations over the coming years. We begin by evaluating the improvement in distance sensitivity of the GW search that arises from using the GRB observation to restrict the time and sky location of the source. We argue that this gives a 25% increase in sensitivity when compared to an all-sky, all-time search, corresponding to more than double the number of detectable GW signals associated with GRBs. Using this, we present the expected rate of joint observations with the advanced LIGO and Virgo instruments, taking into account the expected evolution of the GW detector network. We show that in the early advanced GW detector observing runs, from 2015 to 2017, there is only a small chance of a joint observation. However, as the detectors approach their design sensitivities, there is a good chance of joint observations, provided wide field GRB satellites, such as Fermi and the Inter planetary Network, continue operation. The rate will also depend critically upon the nature of the progenitor, with neutron star-black hole systems observable to greater distances than double neutron star systems. The relative rate of binary mergers and GRBs will depend upon the jet opening angle of GRBs. Consequently, joint observations, as well as accurate measurement of both the GRB rate and binary merger rates, will allow for an improved estimation of the opening angle of GRBs.
TO CONSTRUCT CREDIT RISK FORECAST MODELS Lisiane

Due to the recent growth in the consumer credit market and the consequent increase in default indices, companies are seeking to improve their credit analysis by incorporating objective procedures. Multivariate techniques have been used as an alternative to construct quantitative models for credit forecast. These techniques are based on consumer profile data and allow the identification of standards concerning default behavior. This paper presents a methodology for forecasting credit risk by using three multivariate techniques: discriminant analysis, logistic regression and neural networks. The proposed method (deemed the CRF Model) consists of six steps and is illustrated by means of a real application. An important contribution of this paper is the organization of the methodological procedures and the discussion of the decisions that should be made during the application of the model. The feasibility of the approach proposed was tested in a program for granting credit offered by a network of pharmacies. The use of the models for forecasting credit risk greatly reduces the subjectivity of the analysis, by establishing a standardized procedure that speeds up and qualifies credit analysis.
TEACHERS' INSTRUCTIONAL PRACTICES IN TEACHING ENGLISH AT MALAYSIAN PRIMARY SCHOOLS

Recent trends in Malaysian’s educational policy have focused on meeting the challenges of globalization and internationalization. As English has achieved the status of a major international language, the government of Malaysia has been actively expanding the teaching of English as an essential part of the school curriculum. The issue of how to improve the standard of English proficiency among young learners has been one of the most discussed in Malaysia. Learning English, as envisaged in the ELT curriculum, should be fun and pupil-centred. As part of an effort to examine the state of ELT in Malaysian primary schools, this study looked at the instructional strategies employed by English language teachers in their classrooms. A survey was conducted in six states in Malaysia which represent the northern region, east and west coast of the peninsula and East Malaysia. The sample comprised of 215 English teachers teaching at primary level. The findings of this study revealed that English language teaching practices employed by primary school teachers in Malaysia were in line with the English curriculum stipulated by the Ministry of Education. Data indicated that teachers employed teaching strategies which are learner-centred, interactive, develop oracy and literacy skills. Furthermore, the results also indicated that the teachers’ instructional practices are closely related to their teaching experience.
Extreme Precipitation Estimation with Typhoon Morakot Using Frequency and Spatial Analysis

Typhoon Morakot lashed Taiwan and produced copious amounts of precipitation in 2009. From the point view of hydrological statistics, the impact of the precipitation from typhoon Morakot using a frequency analysis can be analyzed and discussed. The frequency curve, which was fitted mathematically to historical observed data, can be used to estimate the probability of exceedance for runoff events of a certain magnitude. The study integrates frequency analysis and spatial analysis to assess the effect of Typhoon Morakot event on rainfall frequency in the Gaoping River basin of southern Taiwan. First, extreme rainfall data are collected at sixteen stations for durations of 1, 3, 6, 12, and 24 hours and then an appropriate probability distribution was selected to analyze the impact of the extreme hydrological event. Spatial rainfall patterns for a return period of 200-yr with 24-hr duration with and without Typhoon Morakot are estimated. Results show that the rainfall amount is significantly different with long duration with and without the event for frequency analysis. Furthermore, spatial analysis shows that extreme rainfall for a return period of 200-yr is highly dependent on topography and is smaller in the southwest than that in the east. The results not only demonstrate the distinct effect of Typhoon Morakot on frequency analysis, but also could provide reference in future planning of hydrological engineering.
Reference point alignment frequency warp method for speaker adaptation

The variations of speakers' vocal tract shapes result in the variations of the formant positions and sequentially in the variances of the features extracted from every frame of speech. In order to remove or reduce the variations of the formant positions, a speaker adaptation method is proposed and investigated in this paper which is based on a frequency warp function (f.w.f.). The f.w. f. warps the frequency axis so that the variations can be reduced. For a given speaker, some frequency reference points are selected to help to get this f.w. f. by finding the relationship between the positions of these reference points before and after the warping. According to the new positions of those reference points for the given speaker, the f.w. f. can then be constructed. The experimental results show that this method reduces the error rate by an average of 14.5%.
Merchandise Import Demand Function in Saudi Arabia

Merchandise imports in Saudi Arabia is growing steadily and very rapidly, at an average growth rate of 10.04 percent/year during 1975-2011. So, this study is very important to know the merchandise imports determinants in Saudi Arabian economy. This study empirically estimates the critical parameters of merchandise import demand determinants for Saudi Arabia by using Ordinary Least Squares (OLS) approach and Error Correction model during the period (1975-2011). The empirical results obtained show that, in both long run and short run, there are positive and significant relationships between the demand for merchandise import and real gross domestic product, gross capital formation expenditure, private consumption expenditure, government consumption expenditure and the relative price of imports to domestic price. On the other hand, there are positive but insignificant relationship between the demand for merchandise import and international reserves either in the long run or the short run.

A New Single-Phase Asymmetrical Cascaded Multilevel DC-Link Inverter

This paper presents a new single-phase asymmetrical cascaded multilevel DC-link inverter. The proposed inverter comprises two stages. The main stage of the inverter consists of multiple similar cells, each of which is a half-bridge inverter consisting of two switches and a single DC source. All cells are connected in a cascaded manner with a fixed neutral point. The DC source values are not made equal to increase the performance of the inverter. The second circuit is a folded cascaded H-bridge circuit operating at a line frequency. One of the main advantages of this proposed topology is that it is a modular type and can thus be extended to high stages without changing the configuration of the main stage circuit. Two control schemes, namely, low switching with selective harmonic elimination and sinusoidal pulse width modulation, are employed to validate the proposed topology. The detailed approach of each control scheme and switching pulses are discussed in detail. A 150W prototype of the proposed system is implemented in the laboratory to verify the validity of the proposed topology.
Dispersion models for geometric sums

A new class of geometric dispersion models associated with geometric sums is introduced by combining a geometric tilting operation with geometric compounding, in much the same way that exponential dispersion models combine exponential tilting and convolution. The construction is based on a geometric cumulant function which characterizes the geometric compounding operation additively. The so-called v-function is shown to be a useful characterization and convergence tool for geometric dispersion models, similar to the variance function for natural exponential families. A new proof of Renyi’s theorem on convergence of geometric sums to the exponential distribution is obtained, based on convergence of v-functions. It is shown that power v-functions correspond to a class of geometric Tweedie models that appear as limiting distributions in a convergence theorem for geometric dispersion models with power asymptotic v-functions. Geometric Tweedie models include geometric tiltings of Laplace, Mittag-Leffler and geometric extreme stable distributions, along with geometric versions of the gamma, Poisson and gamma compound Poisson distributions.
Analysis of changes in climatological condition: a perspective from Barguna district of Bangladesh

This study investigated the long-term changes in climatological condition, such as temperature, rainfall, humidity, storms, and tidal surge and flooding in Barguna district of Bangladesh. The BMD (Bangladesh Meteorological Department) data were used for temperature, rainfall, and humidity. The data for storms have been collected from secondary sources i.e. various journals, website and various records. This study applied the time series statistical test to examine the long-term changes in climatological condition, such as temperatures (1970-2015), rainfall (1975-2013), humidity (1975-2013), and storms (1987-2007). A parametric technique of trend analysis was used in this study for its inclusive use and simplicity. Data screening and filling missing values were also done before the analyses. The analyses of measured temperature indices that the annual average maximum and minimum mean temperature has increased 1.16°C and 0.56°C respectively at the end of 2015 since 1982 indicating that the weather has been becoming hotter. The analysis of the last 30 years rainfall data of Barguna was compared with national total annual rainfall and no significant change observed. The number of wetter days has been increasing over the time and more rainfall has been happening within small time. There is also a significant change in relative humidity. A total of thirty-five depressions, storms and cyclones hit Barguna district during the last 130 years among which hard hit severe cyclones have occurred in 1935, 1965, 1970 and the most recent cyclone SIDR in 2007 was notable. The study found that storm surge level and surge induced coastal flooding reached from the outfall of Baleshwar River up to 50 km upstream at Morrelganj with high surge level. Therefore, this study will provide a condensed view in further studies in advanced statistical modeling in combination with future scenario analysis for micro and macro scale climate variable changes in Bangladesh.
Spatial synchrony and temporal dynamics of juvenile red drum Sciaenops ocellatus populations in South Carolina, USA

Across a species' range, the population dynamics of some areas may express spatial syn- chrony (i.e. they fluctuate with one another), whereas other areas may express no synchrony (they fluctuate independently). The degree of synchrony and spatial extent of synchrony are important considerations when assessing the population as a whole. We examined these aspects in red drum Sciaenops ocellatus along the coast of South Carolina using long-term survey data of juvenile abun- dance in estuarine areas separated by up to ~200 km. Synchrony of year class strength was detected among areas, but the degree of synchrony declined significantly with distance. By comparison, genetic segregation along the coast was either weak or undetectable (based on allele frequencies at 8 microsatellite loci), although it depended on the year class (2004, 2005 or 2007) of fish that was tested. By standardizing juvenile abundance data across estuaries and survey types, a single, region- wide juvenile time series was generated that covered the 1985-2007 year classes. The juvenile time series correlated significantly with the year class composition of the present-day adult population, which was determined using otoliths collected by a separate survey operating in deeper adult habi- tats. Future work integrating data across even broader spatial scales would assist in the understand- ing of large-scale ecological processes that control fluctuations in red drum populations, and would provide useful information for fishery managers.
The Land/Ocean Biogeochemical Observatory: A robust networked mooring system for continuously monitoring complex biogeochemical cycles in estuaries

An ocean observatory that consists of an array of moored sensor platforms, telemetry, and data collection and dissemination software was designed for monitoring the biogeochemistry and physical dynamics of coastal and estuarine ecosystems. The Land‐Ocean Biogeochemical Observatory (LOBO) consists of robust moorings that can withstand tidal currents and weather. The moorings are highly configurable, can be deployed in waters as shallow as 0.5 m, are relatively easy to maintain, and accommodate a complete array of standard and novel sensors. The sensors communicate with an on‐board controller which relays data to shore in near‐real time. Up to five LOBO moorings have been simultaneously deployed and maintained in Elkhorn Slough, California, since November 2003. Continuous hourly data of biological, chemical, and physical properties are relayed to shore, processed, and disseminated to users through a web interface in near‐real time. This article describes the design, implementation, and functionality of the LOBO monitoring system.
Homogenization of a Continuously Microperiodic Multidimensional Medium

The asymptotic homogenization method is applied to obtain formal asymptotic solution and the homogenized solution of a Dirichlet boundary-value problem for an elliptic equation with rapidly os- cillating coefficients. The proximity of the formal asymptotic solution and the homogenized solution to the exact solution is proved, which provides the mathematical justification of the homogenization pro- cess. Preservation of the symmetry and positive-definiteness of the effective coefficient in the homogenized problem is also proved. An example is presented in order to illustrate the theoretical results.
A study of chaos for processes under small perturbations

In the present paper we prove distributional chaos for the Poincare map in the perturbed equation \[\dot{z}=\left(1 + e^{i\kappa t} |z|^2\right)\bar{z}^2 - N e^{-i\frac{\pi}{3}}. \] Heteroclinic and homoclinic connections between two periodic solutions bifurcating from the stationary solution \(0\) present in the system when \(N = 0\) are also discussed.
Slip distribution and stress changes associated with the 1999 November 12, Düzce (Turkey) earthquake (Mw = 7.1)

The 1999 November 12 Duzce earthquake (M (w) = 7.1) was apparently the eastward extension of the August 17, Izmit earthquake (M (w) = 7.4). The Duzce event caused heavy damage and fatalities in the cities of Duzce and Bolu. Here a finite-fault inversion method with five discrete time windows is applied to derive the co-seismic slip distribution of the Duzce earthquake. The fault plane is best modelled as a 40 x 20 km(2) plane, with a strike of 262degrees and a dip of 65degrees to the north, and that the majority of slip occurred in two distinct patches on either side of the hypocentre, implying bilateral rupture. The possible triggering of this event by the Izmit earthquake is investigated using Coulomb stress modelling of all large events since 1943 with the inclusion of secular loading. The results show that although the Duzce rupture plane was in a stress shadow prior to the Izmit earthquake, that event caused a significant Coulomb stress load, taking the Duzce fault out of the stress shadow, which probably precipitated failure. A comparison of the mapped Coulomb stress change with the inferred slip shows no correlation between the two. Finally, the stress modelling indicates that the northern branch of the North Anatolian fault zone, beneath the Sea of Marmara towards the city of Istanbul, is presently the most highly loaded segment of the North Anatolian Fault Zone.
Modeling and Analysis of a Three-Phase Solid-State Var Compensator (SSVC)

The problems associated with the flow of reactive power in transmission and distribution lines are well known. Several methods of var compensation have been applied in solving these problems. This paper examines the performance of a three-phase solid-state var compensator employed in the power system for reactive power compensation. The principal component of this device is a three-phase pulse-width-modulated voltage source inverter. A mathematical model of the inverter is derived and then used for the transient analysis. Optimization of the ac input power factor can be achieved by adjusting the angle difference between the inverter fundamental output voltage and the utility supply voltage. The open-loop frequency responses obtained show a very stable, high speed performance in the frequency range of interest.
