Energy performance certificates and house prices: a quantile regression approach
Authors: McCord Michael , Haran Martin , Davis Peadar , McCord John 
Published: September 2020

PurposeA number of studies have investigated the relationship between energy performance certificates (EPCs) and house prices. A majority of studies have tended to model energy performance pricing effects within a traditional hedonic conditional mean estimate model. There has been limited analysis that has accounted for the relationship between EPCs and the effects across the pricing distribution. Moreover, there has been limited research examining the “standard cost improvements EPC score”, or “potential score”. Therefore, this paper aims to quantify and measure the dynamic effects of EPCs on house prices across the price spectrum and account for standardised cost-effective retrofit improvements.Design/methodology/approachExisting EPC studies produce one coefficient for the entirety of the pricing distribution, culminating in a single marginal implicit price effect. The approach within this study applies a quantile regression approach to empirically estimate how quantiles of house prices respond differently to unitary changes in the proximal effects of EPCs and structural property characteristics across the conditional distribution of house prices. Using a data set of 1,476 achieved transaction prices, the quantile regression models apply both assessed EPC score and bands and further examine the potential EPC rating for improved energy performance based on an average energy cost improvement.FindingsThe findings show that EPCs are valued differently across the quantiles and that conditional quantiles are asymmetrical. Only property prices in the upper quantiles of the price distribution show significant capitalisation effects with energy performance, and only properties with higher EPC scores display positive significant effects at the higher end of the price distribution. There are also brown discount effects evident for lower-rated properties within F- and G-rated EPC properties at the higher end of the pricing distribution. Moreover, the potential energy efficiency rating (score) also shows increased effects with sales prices and appears to minimise any brown discount effects. The findings imply that energy performance is a complex feature that is not easily “averaged” for valuation effect purposes.Originality/valueWhile numerous studies have investigated the pricing effects of EPCs, they have tended to provide a single estimate to determine the relationship with price. This paper extends the traditional analytical insights beyond the conditional mean estimate by examining the quantiles of the relationship between EPCs and house prices to enhance the understanding of this esoteric and complex issue. In addition, this research applies the assessed energy efficiency potential to establish whether effective cost improvements enhance the relationship with sales price and capitalisation effects.
Global–local supply chain configurations for different production strategies: a comparison between traditional and customized productions
Authors: Macchion Laura , Fornasiero Rosanna 
Published: September 2020

PurposeSupply chain (SC) configuration has gained increased acceptance as an important issue when evaluating new customization possibilities and this evidence has contributed to the strengthening of the debate between global vs local production locations. This work contributes in enrichment of this topic by studying how local or global SC location decisions influence performances by considering a SC point of view, in terms of cost and time, in traditional and customized productions.Design/methodology/approachA discrete event simulation approach, based on experimentation through executable configurations, was used to evaluate different SC scenarios for customized as well as traditional products within the footwear industry.FindingsThe results indicated that to identify proper SC locations, existing trade-offs between the time and cost performances should be studied, avoiding the evaluation of a single performance independently and, instead, adopting a complete SC point of view while considering these performances.Research limitations/implicationsThis evidence has contributed to the reinforcement of the discussion between far-shore destinations vs near-shore production locations. Further studies are encouraged to adopt the present model, in which addition of other variables such as specific manufacturing competences to differentiate suppliers, both local and global suppliers, or the possibility of realizing special types of product customization required by final consumers can be done.Practical implicationsThe paper contributes to the academic and practitioners' debate by proposing a systemic approach to assess SCs’ performances in customized contexts and to compare them to traditional collections. Results indicate that cost and time performance must find a balance that does not necessarily correspond to an exclusively local or global production.Originality/valueThis work contributes to the SC configuration issue by considering the trade-off between efficiency and effectiveness (i.e. SC costs and SC times) for customized productions by reviving and enriching it with an SC perspective in customization contexts.
Discovery behaviour and creation behaviour of Ethiopian entrepreneurs: the implications for the performance of their small tourism firms
Authors: Eyana Shiferaw Muleta , Masurel Enno , Paas Leo J. 
Published: September 2020

PurposeThe purpose of this study is to assess the effects of discovery and creation behaviour in opportunity identification on firm performance in a developing country context. By doing so, the study adds new knowledge and insights in researching the entrepreneurial behaviour types at the start-up phase and their eventual effects on firm performance.Design/methodology/approachThe study was conducted amongst Ethiopian tour operators (n = 118), which are formally established small tourism firms. A survey questionnaire, which is the main data gathering tool in this study, was prepared based on a distinction between discovery and creation behaviour with regard to the seven entrepreneurial actions described by Alvarez and Barney (2007). Hence, 14 multiple-item measurement scales were derived to define the entrepreneurial behaviour types. Firm performance was measured using four indicators. A regression analysis was conducted to predict the effect of entrepreneurial behaviour at the start-up phase on firm performance.FindingsThe findings of this study provide consistent support for the hypothesis that tour-operating firms in Ethiopia founded through creation behaviour instead of discovery behaviour are performing better in terms of sales, employment, profit and asset size change.Research limitations/implicationsThe theoretical contribution of this study is two-fold. First, it provides a scale for measuring the extent to which discovery and/or creation opportunity identification played a role in the start-up phase of the business. Second, the study assesses the effects of discovery behaviour and creation behaviour in opportunity identification on firm performance in a developing country context.Originality/valueThe entrepreneurs' behaviour through which they identify and pursue new opportunities may have a considerable effect on the subsequent performance of their newly established firms. It is, therefore, important to understand effects, which result from differences in entrepreneurs' behaviour at the start-up phase, in terms of outcomes such as firm performance among small businesses. Nonetheless, there is little empirical research conducted in this regard, particularly in the context of developing countries. This study contributes to the literature of entrepreneurship by applying entrepreneurial behaviour types, i.e. discovery and creation, as determinants of small firms' performance in a developing country context. Furthermore, it is one of the few studies concentrating on formal instead of informal operations in an African context.

Published: September 2020

PurposeThe study explored the mediating role of potential and realized absorptive capacities in the relationship between entrepreneurial orientation and radical innovation performance among manufacturing small and medium-sized enterprises (SMEs).Design/methodology/approachEmpirical analysis was based on 357 manufacturing SMEs in Ghana. Various validity and reliability checks were conducted before the presentation of the actual analysis, which was conducted using ordinary least squares approach, run using SPSS (v. 20).FindingsFindings revealed that potential and realized absorptive capacities significantly mediated the relationship between entrepreneurial orientation and radical innovation performance among manufacturing SMEs. Further, it was identified that ambidexterity in absorptive capacity also had a greater effect on radical innovation performance among manufacturing SMEs.Research limitations/implicationsSince the data used were cross-sectional, the relationships measured represent only a snapshot of time. Longitudinal studies could therefore be adopted in the future to complement the cross-sectional conducted.Practical implicationsWhile managers of manufacturing SMEs seek to achieve higher radical innovation performance through entrepreneurial orientation, it should also be noted that both potential and realized absorptive capacities have a significant role to play in this relationship. Managers must therefore also seek to invest time to build both potential and realized absorptive capacities, as they define greater innovation success.Originality/valueSome past studies have considered absorptive capacity as composite variable, therefore added both potential and realized absorptive capacities to form a single variable. Others also presented potential and realized absorptive capacities individually. This current study extends the body of knowledge by presenting an ambidexterity position between potential and realized absorptive capacities.

Authors: Duan Jinyun , Guo Zhaojun , Brinsfield Chad 
Published: September 2020

PurposeThis study draws on uncertainty management theory to advance our understanding of the relationship between leader integrity and employee voice.Design/methodology/approachThe authors collected data in China by surveying 274 supervisor-subordinate dyads at two different points in time. In addition to the direct relationship between leader integrity and employee voice, they also examined the moderating effect of leader consultation and the mediating effect of perceived risk of voice.FindingsThe authors found that leader integrity had a positive effect on employee voice, and perceived risk of voice mediated this relationship. They also found that leader consultation moderated the relationship between leader integrity and employee voice, as well as moderating the mediating role of perceived risk of voice.Originality/valueAlthough prior research has examined the relationship between leadership and voice, it has not clearly explicated the effects of leader integrity on voice. In addition, the findings of this study regarding the moderating role of leader consultation, and the mediating role of perceived risk of voice, offer novel insights regarding the nature of the relationship between leader integrity and employee voice.

Published: September 2020

Purpose
This paper aims to present the dielectrophoresis (DEP) force (FDEP), defined as microelectrofluidics mechanism capabilities in performing selective detection and rapid manipulation of blood components such as red blood cells (RBC) and platelets. The purpose of this investigation is to understand FDEP correlation to the variation of dynamic dielectric properties of cells under an applied voltage bias.

Design/methodology/approach
In this paper, tapered design DEP microelectrodes are used and explained. To perform the characterization and optimization by analysing the DEP polarization factor, the change in dynamic dielectric properties of blood components are observed according to the crossover frequency (fxo) and adjustment frequency (fadj) variation for selective detection and rapid manipulation.

Findings
Experimental observation of dynamic dielectric properties change shows clear correlation to DEP polarization factor when performing selective detection and rapid manipulation. These tapered DEP microelectrodes demonstrate an in situ DEP patterning efficiency more than 95%.

Research limitations/implications
The capabilities of tapered DEP microelectrode devices are introduced in this paper. However, they are not yet mature in medical research studies for various purposes such as identifying cells and bio-molecules for detection, isolation and manipulation application. This is because of biological property variations that require further DEP characterization and optimization.

Practical implications
The introduction of microelectrofluidics using DEP microelectrodes operate by selective detecting and rapid manipulating via lateral and vertical forces. This can be implemented on precision health-care development for lab-on-a-chip application in microfluidic diagnostic and prognostic devices.

Originality/value
This study introduces a new concept to understand the dynamic dielectric properties change. This is useful for rapid, label free and precise methods to conduct selective detection and rapid manipulation of mixtures of RBC and platelets. Further, potential applications that can be considered are for protein, toxin, cancer cell and bacteria detections and manipulation. Implementation of tapered DEP microelectrodes can be used based on the understanding of dynamic dielectric properties of polarization factor analysis.
Public police’s philanthropy and Twitter communications in Canada
Authors: Walby Kevin , Gumieny Crystal 
Published: September 2020

PurposePolice services, police associations and police foundations now engage in philanthropy and these efforts are communicated using social media. This paper examines social media framing of the philanthropic and charitable work of police in Canada.Design/methodology/approachDrawing from discourse and semiotic analyses, the authors examined the ways that police communications frame contributions to charity and community’s well-being. Tweets were analyzed for themes, hashtags and images that conveyed the philanthropic work of police services, police associations as well as police foundations.FindingsThe authors discovered four main forms of framing in these social media communications, focusing on community, diversity, youth and crime prevention. The authors argue that police used these communications as mechanisms to flaunt social capital and to boost perceptions of legitimacy and benevolence.Research limitations/implicationsMore analyses are needed to examine such representations over time and in multiple jurisdictions.Practical implicationsExamining police communications about philanthropy not only reveals insights about the politics of giving but also the political use of social media by police.Originality/valueSocial media is used by organizations to position themselves in social networks. The increased use of social media by police, for promoting philanthropic work, is political in the sense that it aims to bolster a sense of legitimacy.
Informed short selling: evidence from economically linked firms
Authors: Hyder Fawzi , Khoshnoud Mahsa 
Published: September 2020

PurposeThis paper examines how sophisticated and better-informed investors, such as short sellers, trade on information along the supply chain. Given the economic linkages between suppliers and customers, one would expect short sellers to trade on such information and to capitalize on investors' inattention to such economic links.Design/methodology/approachThis paper uses both multivariate regression analysis and portfolio analysis where the time series averages of equally weighted monthly portfolio returns are reported to explore the abnormal returns of long-short trading strategies.FindingsResults indicate that short interest predicts unexpected earnings news, consistent with short sellers extracting information from economic relationships. There is a strong negative relationship between short interest in the supplier firm and the one-month future stock return of the customer firm. This negative relation significantly persists for at least 12 months. One plausible channel explaining the information content of supplier (customer) firm's short interest for the customer (supplier) firms is the short sale constraints on the customer (supplier) firms.Originality/valueThe paper addresses a gap in the literature by examining whether short selling in a firm in the months leading up to a customer's (supplier's) negative shock is negatively correlated to the customer's (supplier's) future performance. Overall, the findings suggest that short sellers play an important role in the price discovery of related firms in the supply chain, which is beyond the direct effects documented in prior literature.

Published: September 2020

AbstractOnion (Allium cepa L.) is one of the most perishable consuming vegetable in the world as an aromatic seasoning and for its health promoting bioactive compounds. However, drying and blanching are two essential thermal treatments in vegetables processing which lead to considerable changes in their properties. This study investigated the effects of temperature (70, 80, and 90 °C), time (2, 4, 6, and 8 hr), and blanching (100 °C for 5 min) followed by drying at 70 °C for 8 hr on the drying kinetics, physicochemical (Ash and total polyphenol content, pH, and titratable acidity), and functional (water solubility index and particle size) properties of onion powder, as well as compared to local market powders. The variety violet of Galmi was used. The results revealed that the moisture content of non‐blanching powder was below 13 ± 0.76 g/100 g with pH under 4. In addition, total polyphenol contents were higher than 512 ± 15.06 mg GAE/100 g DM. These powder showed a small particle size (under 400 µm) and high solubility (≤81.36 ± 2.3 g/100 g DM). Blanching did not affect the powders quality. Local market powders showed a lowest total polyphenol content (386.60 ± 10.02 mg GAE/100 g DM) with large particles (≤800 µm) and a lowest solubility (65.33 ± 1.62 g/100 g DM). Drying at 80 °C for 8 hr without blanching emerge as the best compromise drying conditions resulting in optimal physico‐chemical and functional properties (10.8 ± 0.8 g/100 g, 846.6 ±15.09 mg GAE/100 g DM and 88.12 ± 2.31 g/100 g DM of moisture content, total polyphenol content, and water solubility index, respectively. These findings can contribute to reduce postharvest losses in onion and to stimulate the industrialization of onion enriched‐powder production in Africa.Practical ApplicationThis study provides critical information on onion properties profile during its transformation, on which processor might build on its decision to make an appropriate choice of processing parameters and tools for producing health promoting onion powder meeting modern consumer requirements. In this study, oven‐drying at 80 °C for 8 hr without blanching might be the suitable condition to deliver innovative onion powder tailored specifically to functional ingredients of many food formulations.

Published: September 2020

AbstractIn this work, a new type of tomato puree was obtained from the whole fruit including seeds and skins without any waste. Currently, the food industry aims to develop products that both bring benefits to consumer health and are ecosustainable. Several efforts in fact have been carried out to revalue tomato by‐products, such as seeds and skins, for human use. The physicochemical properties of the whole tomato puree immediately after production and after 6 months of storage were investigated and compared to the properties of a traditional tomato puree. Two tomato varieties were used in this study: Villa Literno and Piccadilly. pH, dry weight, water activity, titratable acidity, reducing sugars, soluble solid, lycopene, polyphenol, and volatile organic compound contents were evaluated. Tomato puree obtained from whole fruits mainly showed higher lycopene (90 to 150 mg/kg), flavonoid (39 to 41 mg/kg), and aldehyde (in particular hexanal) contents and a greater stability over time compared to those of the traditional puree. The proposed process allowed to obtain a tomato puree with a higher content of bioactive compounds, producing no waste.Practical ApplicationIn this study, we proposed a new type of tomato puree made from the whole fruit. The whole tomato puree is richer in phenolic compounds and volatile organic compounds than the traditional puree that is made by removing skins and seeds. It can be an interesting product for the food industries because it is a source of bioactive compounds and reduces to zero the amount of waste.
