Resource configurations for new family venture growth
Authors: Mallon Mark R. , Lanivich Stephen E. , Klinger Ryan L. 
Published: December 2017

PurposeSustainable Family Business Theory states that human, social, and financial capital are important for new family venture growth, yet there may be multiple combinations that could be beneficial. The purpose of this paper is to examine whether all three types of resources are always needed for growth.Design/methodology/approachFuzzy-set Qualitative Comparative Analysis, a configurational method, is used to investigate which combinations of human, social, and financial capital consistently lead to new family venture growth.FindingsMultiple distinct combinations of resources – usually containing some form of human capital along with either social or financial capital – were sufficient for new family ventures to grow.Research limitations/implicationsThe findings contribute to a more accurate Sustainable Family Business Theory in terms of the resource bundles needed to achieve growth. Not all three primary resources are needed at founding for the venture to grow. Results suggest a need for renewed focus on human capital in family venture research, as well as further investigations of the resource configurations uncovered here and their effects on family firm outcomes.Practical implicationsGiven the costs associated with acquiring resources, the findings can inform family entrepreneurs and other stakeholders purposed with assisting new family ventures regarding optimal avenues of achieving growth.Originality/valueThis study advances theory by demonstrating which combinations of primary resources lead to new family venture growth. The findings shed light on how human, social, and financial capital may substitute for each other, as well as how the value of each depends on the presence or absence of the others.
Self-employment: the significance of ability, desire and opportunity
Authors: Broomé Per , Ohlsson Henrik 
Published: December 2017

PurposeThe purpose of this paper is to examine the influence of ability, desire and opportunity on the individual’s intention to be self-employed.Design/methodology/approachThe authors created a database from Swedish national registers consisting of all individuals residing in Sweden sometime during the period 1997-2010 and selected all 333,001 full sibling pairs, 12,810 maternal half sibling pairs and 15,944 paternal half sibling pairs. Three types of entrepreneurs were defined based on information from the Swedish Tax Register. The authors divided the intention to be self-employed into ability and desire and defined ability as a genetic factor and desire as a common family factor. A classical twin model was used to separate the variance of the outcome variables into genetic, common and unshared environmental factors.FindingsThe study demonstrates that the influence from opportunity on the intention to be self-employed is generally strong and that all factors, ability, desire and opportunity, differ, both in size and content, for the three outcomes of entrepreneurs.Originality/valueThe authors divide self-employment into three distinct company types, which enables a sophisticated additive genetic analysis of the ability, desire and opportunity to be self-employed. The authors contribute to the understanding of why individuals become self-employed by examining the influences from internal and external factors of family on the intentions of self-employment.
Forecasting performance of time series models on electricity spot markets: a quasi-meta-analysis
Authors: Gürtler Marc , Paulsen Thomas 
Published: December 2017

PurposeEmpirical publications on the time series modeling and forecasting of electricity prices vary widely regarding the conditions, and the findings make it difficult to generalize results. Against this background, it is surprising that there is a lack of statistics-based literature reviews on the forecasting performance when comparing different models. The purpose of the present study is to fill this gap.Design/methodology/approachThe authors conduct a comprehensive literature analysis from 2000 to 2015, covering 86 empirical studies on the time series modeling and forecasting of electricity spot prices. Various statistics are presented to characterize the empirical literature on electricity spot price modeling, and the forecasting performance of several model types and modifications is analyzed. The key issue of this study is to offer a comparison between different model types and modeling conditions regarding their forecasting performance, which is referred to as a quasi-meta-analysis, i.e. the analysis of analyses to achieve more general findings independent of the circumstances of single studies.FindingsThe authors find evidence that generalized autoregressive conditional heteroscedasticity models outperform their autoregressive–moving-average counterparts and that the consideration of explanatory variables improves forecasts.Originality/valueTo the best knowledge of the authors, this paper is the first to apply the methodology of meta-analyses in a literature review of the empirical forecasting literature on electricity spot markets.
Teachers’ pedagogical reasoning and reframing of practice in digital contexts
Authors: Holmberg Jörgen , Fransson Göran , Fors Uno 
Published: December 2017

Purpose
The purpose of this paper is to advance the understanding of teachers’ reframing of practice in digital contexts by analysing teachers’ pedagogical reasoning processes as they explore ways of using information and communication technologies (ICT) to create added pedagogical value.

Design/methodology/approach
A design-based research (DBR) approach is employed, in which the on-site researcher collaborates with eight teachers of English as a foreign language in four Swedish schools over a period of two years. Multiple data sources are included for thematic coding and analysis. The technological pedagogical content knowledge (TPACK) framework is used as a conceptual construct in the analysis.

Findings
The findings show that teachers’ pedagogical reasoning is a complex and multidimensional process and is closely integrated with teachers’ reframing of practice. Common characteristics in the teachers’ reframing of practice are identified. The results highlight the reciprocal relationship between developments in teachers’ pedagogical reasoning and TPACK development and the need for a distinction between general and specific, theoretical and practical TPACK.

Research limitations/implications
An increased focus on TPACK research on teachers’ pedagogical reasoning is required. DBR is a relevant approach for this.

Practical implications
The pedagogical uses of ICT identified as adding value could benefit teachers in other contexts.

Originality/value
Rich data from multiple design contexts are collected and analysed over time through DBR. The paper contributes new knowledge about the process of pedagogical reasoning and its relation to teachers’ reframing of practice. The paper also contributes to TPACK theory development.
Supporting asylum seekers and refugees who suffer chronic pain: an experience
Authors: Negron Andreia 
Published: December 2017

Purpose
Refugees and asylum seekers often present complex health needs, including chronic pain, related to traumatic experiences. To help them manage their pain, the Wellbeing and Self-Care Service provides health advice, pain education, soft tissue manual therapies and training in self-help techniques. The paper aims to discuss these issues.

Design/methodology/approach
A 0-10 pain scale (0= no pain, 10= very severe pain) is used to record reported intensity of pain before and after treatment. Change is analysed by comparing the position of a tick on the scale before and after therapy. In follow-up appointments, attendees were asked whether they were practicing self-help techniques; if they experienced improvement, and if so, how long it lasted; and whether they had reduced the use of painkillers.

Findings
From April 2014 to March 2015, 192 people were seen in 524 therapeutic encounters (63 per cent females, 37 per cent males). In total, 173 (90 per cent) were asylum seekers and refugees. Of the refugees and asylum seekers, 40 per cent were torture survivors. After treatment, 53 per cent of the 192 people treated showed a major reduction of pain, and 39 per cent a moderate reduction. In follow-up encounters, 87 per cent reported improvement (⩾2 weeks, 46 per cent), 70 per cent reported a reduction in the use of painkillers and 83 per cent reported that they practiced self-help techniques to different degrees.

Originality/value
Soft tissue manual therapies combined with education and training that emphasise communication and active patient participation in the healing process are non-invasive therapeutic approaches that can confer temporary relief to refugees and asylum seekers suffering chronic pain.

Published: December 2017

PurposeThe purpose of this paper is to develop a monitoring multiple-stream processes control chart with a finite mixture of probability distributions in the manufacture industry.Design/methodology/approachData were collected during production of a wheat-based dough in a food industry and the control charts were developed with these steps: to collect the master sample from different production batches; to verify, by graphical methods, the quantity and the characterization of the number of mixing probability distributions in the production batch; to adjust the theoretical model of probability distribution of each subpopulation in the production batch; to make a statistical model considering the mixture distribution of probability and assuming that the statistical parameters are unknown; to determine control limits; and to compare the mixture chart with traditional control chart.FindingsA graph was developed for monitoring a multi-stream process composed by some parameters considered in its calculation with similar efficiency to the traditional control chart.Originality/valueThe control chart can be an efficient tool for customers that receive product batches continuously from a supplier and need to monitor statistically the critical quality parameters.
A new double exponentially weighted moving average control chart using repetitive sampling
Authors: Adeoti Olatunde Adebayo 
Published: December 2017

Purpose
The purpose of this paper is to propose a double exponentially weighted moving average control chart using repetitive sampling (RS-DEWMA) for a normally distributed process variable to improve the efficiency of detecting small process mean shift.

Design/methodology/approach
The algorithm for the implementation of the proposed chart is developed and the formulae for the in-control and out-of-control average run lengths (ARLs) are derived. Tables of ARLs are presented for various process mean shift. The performance of the proposed chart is investigated in terms of the average run-length for small process mean shift and compared with the existing DEWMA control chart. Numerical examples are given as illustration of the design and implementation of the proposed chart.

Findings
The proposed control chart is more efficient than the existing DEWMA control chart in the detection of small process mean shifts as it consistently gives smaller ARL values and quickly detects the process shift. However, the performance of the proposed chart relatively deteriorates for large smoothing constants.

Practical implications
The application of repetitive sampling in the control chart literature is gaining wide acceptability. The design and implementation of the RS-DEWMA control chart offers a new approach in the detection of small process mean shift by process control personnel.

Originality/value
This paper fills a gap in the literature by examining the performance of the repetitive sampling DEWMA control chart. The use of repetitive sampling technique in the control chart is discussed in the literature, however, its use based on the DEWMA statistic has not been considered in this context.
A new lifetime distribution with applications in inventory and insurance
Authors: Chowdhury Shovan , Nanda Asok K. 
Published: December 2017

PurposeThe purpose of this paper is to introduce a new probability density function having both unbounded and bounded support with a wider applicability. While the distribution with bounded support on [0, 1] has applications in insurance and inventory management with ability to fit risk management data on proportions better than existing bounded distributions, the same with unbounded support is used as a lifetime model and is considered as an attractive alternative to some existing models in the reliability literature.Design/methodology/approachThe new density function, called modified exponential-geometric distribution is derived from the exponential-geometric distribution introduced by Adamidis and Loukas (1998). The support of the density function is shown to be both unbounded and bounded depending on the values of one of the shape parameters. Various properties of the density function are studied in detail and the parameters are estimated through maximum likelihood method of estimation. A number of applications related to reliability, insurance and inventory management are exhibited along with some useful data analysis.FindingsA single probability distribution with both unbounded and bounded support, which does not seem to exist in the reliability literature, is introduced in this paper. The proposed density function exhibits varying shapes including U-shape, and the failure rate also shows increasing, decreasing and bathtub shapes. The Monte Carlo simulation shows that the estimates of the parameters are quite stable with low standard errors. The distribution with unbounded support is shown to have competitive features for lifetime modeling through analysis of two data sets. The distribution with bounded support on [0, 1] is shown to have application in insurance and inventory management and is found totdata on proportions related to risk management better than some existing bounded distributions.Originality/valueThe authors introduce an innovative probability distribution which contributes significantly in insurance and inventory management besides its remarkable statistical and reliability properties.

Authors: Xie Fangwei , Ding Erming , Xuan Rui , Zhang Xinxing , Feng Yixian , Zhu Jie 
Published: December 2017

Purpose
The purpose of this paper is to study the influence rules of geometric parameters on deformation of valve slices.

Design/methodology/approach
Based on the theory of flexural deformation of elastic thin slice, differential functions of deformation for both single and multi-slices are given and derived in detail. Furthermore, the effects of geometric dimensions on deformation are analyzed particularly by using Matlab/simulink.

Findings
The results indicated that the deformation decreases with the increment of fixed ring radius ra, slice thickness h, and its number n. Meanwhile, the deformation increases with a rise of slice radius rb, throttle position rk, the radius ratio λ1 and thickness ratio λ2 of slices.

Originality/value
This research can provide some theoretical supports for the parametric and optimal design of adjustable damping shock absorber.
Natural disasters and their policy implications for business schools
Authors: Wynne Kevin , Leary Douglas , Sholes Jay 
Published: December 2017

Purpose
The purpose of this paper is to analyze the impact of Hurricane Sandy and a series of snowstorms that affects two universities in the northeast.

Design/methodology/approach
A survey instrument was used to assess the educational impact that these storms had on the college students at two AACSB business schools located in the New York City area. Utilizing 519 observations from Hurricane Sandy in 2012 and 441 observations from the snowstorms in the Spring of 2015, the paper is able to document the impact these natural disasters had on the college students in a few selected areas. The paper conducts univariate t-statistics for mean differences, principal component analysis determining eigenvalues, and a multivariate logit model using log likelihood functions.

Findings
The empirical results illustrate that the two different events had different impacts upon the students. In addition, the events in certain circumstances had different impacts upon the student responses between the two universities. Students perceived an increase in preparation by the faculty more significantly when make-up classes were conducted in classrooms as opposed to additional online work. Dorm residents at the suburban university felt greater financial hardship than their counterpart dorm residents at the urban university. Commuter students overall felt an increase in concerns related to their overall education.

Originality/value
The empirical results are robust to multiple specifications, and the authors are able to identify the predominate factors that affected the students during the two natural disasters. The unique survey based nature of the data set provides valuable insights into the students’ behavior that has not previously been documented.
Investigating a time‐shift extended imaging condition in a Kirchhoff pre‐stack depth migration algorithm
Authors: O'Brien Gareth Shane , Delaney Sean Joseph , Igoe Michael , Doherty John , Colhoun Andrew 
Published: December 2017

ABSTRACTExtracting true amplitude versus angle common image gathers is one of the key objectives in seismic processing and imaging. This is achievable to different degrees using different migration techniques (e.g., Kirchhoff, wavefield extrapolation, and reverse time migration techniques) and is a common tool in exploration, but the costs can vary depending on the selected migration algorithm and the desired accuracy. Here, we investigate the possibility of combining the local‐shift imaging condition, specifically the time‐shift extended imaging condition, for angle gathers with a Kirchhoff migration. The aims are not to replace the more accurate full‐wavefield migration but to offer a cheaper alternative where ray‐based methods are applicable and to use Kirchhoff time‐lag common image gathers to help bridge the gap between the traditional offset common image gathers and reverse time migration angle gathers; finally, given the higher level of summation inside the extended imaging migration, we wish to understand the impact on the amplitude versus angle response. The implementation of the time‐shift imaging condition along with the computational cost is discussed, and results of four different datasets are presented. The four example datasets, two synthetic, one land acquisition, and a marine dataset, have been migrated using a Kirchhoff offset method, a Kirchhoff time‐shift method, and, for comparison, a reverse time migration algorithm. The results show that the time‐shift imaging condition at zero time lag is equivalent to the full offset stack as expected. The output gathers are cleaner and more consistent in the time‐lag‐derived angle gathers, but the conversion from time lag to angle can be considered a post‐processing step. The main difference arises in the amplitude versus offset/angle distribution where the responses are different and dramatically so for the land data. The results from the synthetics and real data show that a Kirchhoff migration with an extended imaging condition is capable of generating subsurface angle gathers. The same disadvantages with a ray‐based approach will apply using the extended imaging condition relative to a wave equation angle gather solution. Nevertheless, using this approach allows one to explore the relationship between the velocity model and focusing of the reflected energy, to use the Radon transformation to remove noise and multiples, and to generate consistent products from a ray‐based migration and a full‐wave equation migration, which can then be interchanged depending on the process under study.
‘All pent up together’: Representations of Friendship in Fictions of Girls’ Boarding‐Schools, 1680‐1800
Authors: Haslett Moyra 
Published: December 2017

AbstractStudies of female education have emphasised the contexts of criticism and anxiety that surrounded girls’ boarding‐schools in the eighteenth century. Histories of education, however, have not considered fictional representations of these schools, which, as the century progressed, suggest an increasing acceptance of the schools and offer striking defences of the importance and significance of female friendship. This article sketches a history of representations of girls’ schools across the period 1680‐1800 in order to show this development and to position Sarah Fielding's The Governess as a key influence in this history.
Use of agricultural land by breeding waders in low‐intensity farming landscapes
Authors: Jóhannesdóttir L. , Alves J. A. , Gill J. A. , Gunnarsson T. G. 
Published: December 2017

AbstractAgriculture is one of the primary threats to biodiversity but agricultural land can also provide key resources for many species and, in some parts of the world, agricultural land supports important populations of species of conservation concern. In these cases, it is important to understand species’ use of agricultural land before further expansion or intensification of agricultural activities occurs. Agriculture in Iceland is still relatively low in intensity and extent, and internationally important populations of several breeding bird species are abundant in farmed regions. In these high latitude landscapes, agricultural land could provide resources that help to support these species, and the consequences of future agricultural expansion will depend on the nature of these relationships. To address these issues, we conducted surveys of bird abundance at 64 farms in areas of Iceland that vary in underlying soil productivity, and quantified (a) levels of breeding bird use of farmed land managed at three differing intensities, ranging from cultivated fields to semi‐natural land and (b) changes in patterns of use throughout the breeding season, for an assemblage of species. Breeding birds use all three land management types in large numbers but, overall, bird abundance is lower in more intensively managed farmland. However, more intensively managed agricultural land supports higher densities of birds than semi‐natural habitats in areas with lower underlying productivity. This suggests that in landscapes in which agricultural land does not yet dominate, conservation and commercial production can co‐exist, especially in areas of low productivity. Areas like Iceland, in which agricultural land still supports large populations of internationally important species, are rare and this study highlights the need to protect these systems from the agricultural development that has led to widespread biodiversity loss throughout most of the world.
