Do ethical work climates influence supplier selection decisions in public organizations? The moderating roles of party politics and personal values
Authors: Essien Eyo Emmanuel , Kostopoulos Ioannis , Konstantopoulou Anastasia , Lodorfos George 
Published: July 2019

PurposeThe purpose of this paper is to examine the relationship between ethical work climates (EWCs) and supplier selection decisions (SSDs), and the moderating roles of party politics and personal values on this relationship.Design/methodology/approachA total of 600 senior-level personnel from 40 Nigerian public organizations were surveyed using structured questionnaires. Multiple regression analysis was used to test the hypotheses developed for the study after assessing construct reliability and validity.FindingsResults show that both high and low levels of external political pressures significantly reduce the perception that organizational SSDs are ruled based and pro-social in nature. Furthermore, regardless of the level of perception of instrumental personal values by employees, instrumental ethical climates significantly determine SSDs; principled/cosmopolitan climate and benevolent/cosmopolitan climate only become significant perceptible determinants when there is less room for the accommodation of personal goals during SSD processes.Research limitations/implicationsThis study only examined the relationship between ethical climate perceptions and SSDs without controlling for the effects of some important possible intervening variables on this relationship. Therefore, the study encouraged future researcher to enhance the generalizability of the findings by incorporate relevant control variables in the model, as well as examining other decision phases in the public buying process.Originality/valueThis study is original to the extent that only a few studies in the literature are devoted to perceptions of EWCs in African organizations, and no previous studies have examined this phenomenon in relation to SSDs in Nigerian public firms.
Ramadan’s impact on the optimism of analysts’ recommendations
Authors: Satt Harit , Nechbaoui Sarah , Hassan M. Kabir , Izadi Selma 
Published: July 2019

Purpose
This paper aims to document the impact of Ramadan on the optimism of analysts’ recommendations taking as a sample the countries of the MENA region during the period between 2004 and 2015. The choice of these countries can be explained by the fact that their population is predominantly of a Muslim faith (The Future of World Religions: Population Growth Projections, 2010-2050, 2015).

Design/methodology/approach
The authors used univariate and multivariate regression models to highlight the existence of the Ramadan effect on the optimism of analysts. They have found that pre-holiday optimism is significantly lower than post-holiday optimism.

Findings
This paper also documented the effect of analysts’ experience and information uncertainty on the analysts’ optimism level that allowed us to infer that low experience enhances optimism, while environment with low information uncertainty tends to decrease the level of optimism.

Originality/value
Previous research on this topic has investigated the effect of months of the year, turns of the month and days-of-the-week on the behavior of stock exchanges. Another strand of the literature also analyzed the effect of holidays on the latter. However, this is the first attempt to investigate this effect on analysts’ recommendations optimism when the holiday period is related to Islam.

Published: July 2019

Purpose
The purpose of this study is to explore the integration of Shariah compliance in the information system of Islamic financial institutions (IFIs) in the context of Malaysia.

Design/methodology/approach
By applying qualitative approach in the form of in-depth/structured interview of qualified respondents within Islamic financial industries.

Findings
The result of this study indicates that information system advancement will give an increasing level of competitive advantages. Also, the result indicates that the internal control and information system played a vital role in ensuring the Shariah compliance and translating and circulating the Shariah guidelines among the IFIs’ departments and staffs. In terms of Shariah integration in information system, there is a consideration during the development of an information system. Shariah will be an element that needs to be accounted for to develop the information system for IFI.

Research limitations/implications
This includes the scope of the study which is based on Malaysian Islamic banks only. Hence, future studies are recommended to extend this endeavor to other contexts as well. Furthermore, although the initial sample was covering nine IFIs, only two IFIs accepted to participate in the interview. It is suggested that the future studies involve more participants and apply different research techniques such as focus groups or questionnaire survey.

Practical implications
Make sure employees who are in charge of performing any function related to Shariah (i.e. Shariah review, Shariah audit, Shariah research, Shariah risk management) have a basic knowledge on information technology (IT) and information system. Continuous trainings for IFIs’ employees covering the information system and internal control system issues related to the Shariah compliance. Focus on seminars and conferences on outstanding issues related to information system technology in IFIs. Promoting programs and subjects specialized in information system technology in IFIs. IFIs should allocate a budget for system development or enhancement in the financial budget ensuring that IT system is incorporated in Shariah compliance. IFIs should consider enhancement of Shariah compliance encompass and the alignment into the IT system as continuous process, as well as one of their strategic plan aspects. Bank Negara Malaysia as a regulatory body of IFIs should emphasize on regulating the Shariah aspects with regard to the IT system.

Originality/value
This paper’s contributions lies in the enhancement of the development of the Shariah compliance literature, as well in the integration of Shariah compliance and information system in IFIs.
Governing the “good citizen” and shaping the “model city” to tackle climate change
Authors: Berquier Roger , Gibassier Delphine 
Published: July 2019

Purpose
Cities are key actors in the fight against climate change. They have developed integrated strategies harnessing the power of information and communication technologies (ICT) as part of the move towards smart(er) cities. In spite of our knowledge of the role of technological infrastructure in tackling climate change, the role of governance mechanisms to actively pursue environmental sustainability is often understated. Therefore, the purpose of this paper is to analyse governmentality mechanisms developed by a small town in Europe to render energy savings and new energy sources visible and to create new identities with which the citizen and other cities could then identify with, thereby participating in the fight against climate change.

Design/methodology/approach
Data were gathered through non-participant observation, interviews and access to internal data from the city’s energy control project.

Findings
The outcome of these governmentality mechanisms was to create two new identities: the “good citizen”, responsible to lower his impact on climate change, and the “model city”, a laboratory that would serve as a guide for future policies to tackle climate change at the city level. While the “model city” was successful and identification happened with other small cities taking example from it, the “good citizen” failed and inhabitants did not identify with this role model that was defined for them as a way to participate in the fight against climate change.

Practical implications
This case study is a concrete example, based on a longitudinal study, of a city’s strategy and actions on climate change. Other small cities will be able to use this case study to gauge their possibilities for action on climate change. Notably, it is an example of how a network of mechanisms can achieve results in CO2 emissions reduction. It also demonstrates the difficulty to enrol citizens into an environmental sustainability scheme.

Social implications
This paper has implications for how climate change can be tackled in rural areas by small cities. While the role of organizations and large cities (e.g. C40 city network) has been acknowledged, there is a possibility for smaller local actors to act upon grand challenges with local strategies and their own governmentality mechanisms.

Originality/value
The case study contributes to the literature on cities, bringing new insights into how they can become actors of climate change beyond acting on internal controls, and the literature on governmentality by demonstrating how mechanisms can act upon a population without being calculative.
Brand it green: young consumers’ brand attitudes and purchase intentions toward green brand advertising appeals
Authors: Gahlot Sarkar Juhi , Sarkar Abhigyan , Yadav Rambalak 
Published: July 2019

Purpose
This paper aims to analyze the impacts of distinct advertising appeals on brand attitudes and purchase intentions toward green brands across two different product categories (technology-intensive and technology non-intensive) among the young adult consumers.

Design/methodology/approach
On the basis of focus group discussion, recyclable shopping bags (technology non-intensive) and hybrid cars (technology intensive) were identified as two product categories for the final study. A total of eight advertisement copies were developed (three in each product class + two control group ads) and distributed across 240 young consumers. A 4 (three advertising appeals + one control group) × 2 (product classes) between group experimental design was used to test the hypotheses formulated.

Findings
The study findings show that all the three advertisement appeals significantly influence attitudes and purchase intentions toward green brands across both the product categories. However, it was also found that functional appeal generated significantly lower mean scores for brand attitude and purchase intention for recyclable shopping bags compared to hybrid cars, whereas emotional appeal generated significantly lower mean scores for brand attitude, as well as purchase intention for hybrid cars compared to bags. This implies that functional green ad appeal would be more effective for technology-intensive products and emotional green ad appeal would be more effective for technology non-intensive products. Self-expressive green ad appeal was found to be equally effective in impacting brand attitudes and purchase intentions across both product categories.

Originality/value
The value of this research lies in investigating how the effects of distinct green brand advertising appeals on brand attitude and purchase intention can vary across technology-intensive and technology non-intensive products.
Wavelet transform‐based seismic facies classification and modelling: application to a geothermal target horizon in the NE German Basin
Authors: Bauer Klaus , Norden Ben , Ivanova Alexandra , Stiller Manfred , Krawczyk Charlotte M. 
Published: July 2019

ABSTRACTAt the geothermal test site near Groß Schönebeck (NE German Basin), a new 3D seismic reflection survey was conducted to study geothermal target layers at around 4 km depth and 150°C. We present a workflow for seismic facies classification and modelling which is applied to a prospective sandstone horizon within the Rotliegend formation. Signal attributes are calculated along the horizon using the continuous Morlet wavelet transform. We use a short mother wavelet to allow for the temporal resolution of the relatively short reflection signals to be analysed. Time‐frequency domain data patterns form the input of a neural network clustering using self‐organizing maps. Neural model patterns are adopted during iterative learning to simulate the information inherent in the input data. After training we determine a gradient function across the self‐organizing maps and apply an image processing technique called watershed segmentation. The result is a pattern clustering based on similarities in wavelet transform characteristics. Three different types of wavelet transform patterns were found for the sandstone horizon. We apply seismic waveform modelling to improve the understanding of the classification results. The modelling tests indicate that thickness variations have a much stronger influence on the wavelet transform response of the sandstone horizon compared with reasonable variations of seismic attenuation. In our interpretation, the assumed thickness variations could be a result of variable paleo‐topography during deposition of predominantly fluvial sediments. A distinct seismic facies distribution is interpreted as a system of thicker paleo‐channels deposited within a deepened landscape. The results provide constraints for the ongoing development of the geothermal test site.
High‐resolution seismic imaging of crooked two‐dimensional profiles in greenstone belts of the Canadian shield: results from the Swayze area, Ontario, Canada
Authors: Cheraghi Saeid , Naghizadeh Mostafa , Snyder David , Haugaard Rasmus , Gemmell Thomas 
Published: July 2019

ABSTRACTIn 2017, the Metal Earth multi‐disciplinary exploration project acquired a total of 921 km of regional deep seismic reflection profiles and 184 km of high‐resolution seismic reflection profiles in the Abitibi and Wabigoon greenstone belts of the Superior province of Canada. The Abitibi belt hosts several world‐class mineral deposits, whereas the Wabigoon has sparse economic mineral deposits. Two high‐resolution surveys in the Swayze area, a poorly endowed part of the western Abitibi greenstone belt, served as pioneer surveys with which to better understand subsurface geology and design a strategy to process other surveys in the near future. Swayze seismic data were acquired with crooked survey geometries along roads. Designing an effective seismic processing flow to address these geometries and complex geology required straight common midpoint lines along which both two‐dimensional prestack dip‐moveout correction and poststack migration processing were applied. The resulting seismic sections revealed steeply dipping and subhorizontal reflections; some correlate with folded surface rocks. An interpreted fault/deformation zone imaged in Swayze north would be a target for metal endowment if it extends the Porcupine–Destor structure. Because of the crooked line geometry of the surveys, two‐dimensional /three‐dimensional prestack time migration and swath three‐dimensional processing were tested. The prestack time migration algorithm confirmed reflections at the interpreted base of the Abitibi greenstone belt. The swath three‐dimensional images provided additional spatial details about the geometries of some reflections, but also had less resolution and did not detect many reflectors observed in two dimensions. Geological contacts between felsic, mafic and ultramafic greenstone rock layers are thought the main cause of reflectivity in the Swayze area.
An asymmetric partisanship effect: House price fluctuations and party positions
Authors: BECKMANN PAUL 
Published: July 2019

AbstractPolitical economy arguments on party behaviour usually address parties of the left and the right. This article introduces a novel argument that portrays house price changes as an economic signal that right‐wing parties disproportionately respond to in their programmatic positioning. This asymmetric partisanship effect is driven by homeowners’ importance for right‐wing parties as a core voter group. Increasing house prices improve homeowners’ economic prospects. Right‐wing parties thus have some flexibility to reach out to undecided voters by targeting the centre of the political spectrum. Falling house prices, however, signal worsening economic outlooks for homeowners. Right‐wing parties thus have a strong incentive to send out signals of reassurance and prioritise their core voters. For a sample of Organisation for Economic Cooperation and Development (OECD) countries from 1970 to 2014, the findings support this argument. Right‐wing parties move programmatically leftwards with booming house prices and rightwards when house prices fall, while parties of the left do not respond systematically.
How to better estimate leaf area index and leaf angle distribution from digital hemispherical photography? Switching to a binary nonlinear regression paradigm

Abstract

Probabilistic modelling of gaps for light–canopy interactions has long served as a theoretical basis to estimate vegetation structural parameters—leaf area index (LAI) and leaf angle distribution (LAD)—from optical measurements such as hemispherical photos. Direct inversion of such probabilistic models provides a reliable statistical algorithm for parameter estimation, but this inferential paradigm has been seldom explored. Even worse, many classical LAI algorithms implicitly assume “wrong” statistical models inconsistent with the underlying probabilistic gap models—a subtle issue not articulated before but known to cause practical issues.

Here, we clarified how to improve LAI and LAD estimation by directly inverting binary gap/non‐gap data of hemispherical photos via binary nonlinear regression (BNR). We implemented the new BNR method and some classical algorithms in an R package “hemiphoto2LAI”, comprising a total of 135 models for LAI estimation.

Compared to classical algorithms, BNR features many theoretical advantages and allows estimating LAI and LAD simultaneously. BNR can address questions difficult to answer by classical algorithms (e.g. how better is one LAD than another?). We demonstrated the utility of the BNR paradigm based on both synthetic and real data.

Overall, BNR is statistically more justifiable but its potential has been under‐appreciated. We encourage the community to embrace this new paradigm for reliable analyses of hemispherical photos or other gap data for canopy research.

AbstractAberrant activation of the MET/hepatocyte growth factor (HGF) receptor participates in the malignant behavior of cancer cells, such as invasion‐metastasis and resistance to molecular targeted drugs. Many mutations in the MET extracellular region have been reported, but their significance is largely unknown. Here, we report the dysregulation of mutant MET originally found in a lung cancer patient with Val370 to Asp370 (V370D) replacement located in the extracellular SEMA domain. MET‐knockout cells were prepared and reconstituted with WT‐MET or V370D‐MET. HGF stimulation induced MET dimerization and biological responses in cells reconstituted with WT‐MET, but HGF did not induce MET dimerization and failed to induce biological responses in V370D‐MET cells. The V370D mutation abrogated HGF‐dependent drug resistance of lung cancer cells to epidermal growth factor receptor‐tyrosine kinase inhibitors (EGFR‐TKI). Compared with WT‐MET cells, V370D‐MET cells showed different activation patterns in receptor tyrosine kinases upon exposure to survival/growth‐stressed conditions. Surface plasmon resonance analysis indicated that affinity between the extracellular region of V370D‐MET and HGF was reduced compared with that for WT‐MET. Further analysis of the association between V370D‐MET and the separate domains of HGF indicated that the SP domain of HGF was unchanged, but its association with the NK4 domain of HGF was mostly lost in V370D‐MET. These results indicate that the V370D mutation in the MET receptor impairs the functional association with HGF and is therefore a loss‐of‐function mutation. This mutation may change the dependence of cancer cell growth/survival on signaling molecules, which may promote cancer cell characteristics under certain conditions.

Published: July 2019

AbstractIn recent years, personalized fabrication has received considerable attention because of the widespread use of consumer‐level three‐dimensional (3D) printers. However, such 3D printers have drawbacks, such as long production time and limited output size, which hinder large‐scale rapid‐prototyping. In this paper, for the time‐ and cost‐effective fabrication of large‐scale objects, we propose a hybrid 3D fabrication method that combines 3D printing and the Zometool construction set, which is a compact, sturdy and reusable structure for infill fabrication. The proposed method significantly reduces fabrication cost and time by printing only thin 3D outer shells. In addition, we design an optimization framework to generate both a Zometol structure and printed surface partitions by optimizing several criteria, including printability, material cost and Zometool structure complexity. Moreover, we demonstrate the effectiveness of the proposed method by fabricating various large‐scale 3D models.
