Where are fossil fuels prices heading?
Authors: Rostan Pierre , Rostan Alexandra 
Published: January 2020

PurposeThe purpose of this paper is to present forecasts of fossil fuels prices until 2030 with spectral analysis to provide a clearer picture of this energy sector.Design/methodology/approachFossil fuels prices time series are decomposed in simpler signals called approximations and details in the framework of the one-dimensional discrete wavelet analysis. The simplified signals are recomposed after Burg extension.FindingsIn 2019-2030 average price forecasts of: West Texas intermediate (WTI) oil ($58.67) is above its 1986-2030 long-term mean of $47.83; and coal ($81.01) is above its 1980-2030 long-term mean of $60.98. On the contrary, 2019-2030 average of price forecasts of: Henry Hub natural gas ($3.66) is below its 1997-2030 long-term mean of $4; heating oil ($0.64) is below its 1986-2030 long-term mean of $1.16; propane ($0.26) is below its 1992-2030 long-term mean of $0.66; and regular gasoline ($1.45) is below its 2003-2030 long-term mean of $1.87.Originality/valueFossil fuels prices projections may relieve participants of WTI oil and coal markets but worry participants of Henry Hub, heating oil, propane and regular gasoline markets including countries whose economy is tied to energy prices.
Effect of education–occupation mismatch on happiness
Authors: Chen Naiwei , Chen Ho-Chyuan , Lin Shih-Yu 
Published: January 2020

Purpose
Prior research mostly focuses on the effect of over-education on happiness, whereas the effect of under-education on happiness has received minimal attention. In addition, no research to date has examined the effect of both over- and under-education on happiness by using a full spectrum of workers. Thus, the purpose of this paper is to fill this research gap.

Design/methodology/approach
The ordered probit model is estimated to examine the effect of the education–occupation mismatch on happiness based on 2012 survey data from Taiwan.

Findings
The results generally indicate that over-education positively affects happiness, whereas under-education has a minimal effect. The effect of the education–occupation mismatch on happiness also varies with different age groups. Specifically, over-education positively affects happiness except for workers aged 42 and above, whereas negative effects of under-education are found only among workers aged between 32 and 42 when their social network is insufficiently extensive. Moreover, a worker’s social network as a non-pecuniary factor, rather than income as a pecuniary factor, is a major channel through which education enhances happiness.

Originality/value
Given the limited and mixed evidence on the relationship between over-education and happiness, this study contributes to the existing literature by examining whether and how the education–occupation mismatch (over- and under-education) affects the happiness of workers both directly and indirectly via pecuniary and non-pecuniary factors. The research issue remains unexplored to date. Addressing such a question should help explain the persistent trend in pursuing higher education in Taiwan, although highly educated people may suffer from unemployment and an education–occupation mismatch.

Positive aspects of disability among college students
Authors: Sniatecki Jessica L. , Ashton Jennifer Randhare , Perry Holly B. , Snell Linda H. 
Published: January 2020

PurposeThe number of students with disabilities pursuing a college education has increased dramatically in recent years (Hall and Belch, 2000; Hitchings et al., 2011; Horn et al., 2006; Retish and Horvath, 2005; Snyder et al., 2016; Stodden et al., 2001), yet, evidence suggests that these students continue to encounter significant challenges and barriers that may have a dramatic effect on their college experience (Madaus and Shaw, 2006; Sniatecki et al., 2015; Stodden et al., 2001). The paper aims to discuss this issue.Design/methodology/approachPositive experiences and aspects of being a college student with a disability have not garnered as much consideration and have received little attention in the professional literature to date. The current study sought to address this gap through examination of positive aspects of disability among 12 undergraduate students. Data were gathered via qualitative interviews.FindingsResults included five distinct themes related to students’ experiences: personal growth and self-acceptance; empathy/understanding; advocacy and teaching others; unique relationship experiences and opportunities; and drive/determination/perseverance.Research limitations/implicationsThe implications of these themes and future directions for research on positive aspects of disability are also addressed.Originality/valueThe results of this study provide support for the social model of disability as a lens to view individuals with disabilities as complete people who, with their impairments, can and do go on to lead positive and meaningful lives.

Authors: Kemper Joya A. , Ballantine Paul W. 
Published: January 2020

Purpose
This paper aims to explore how the socio-ecological model can be expanded to address wicked problems that are perpetuated by marketing systems through examining the ways the external environment can be targeted.

Design/methodology/approach
The authors used an extended socio-ecological model to provide a framework for social marketers to combat climate change through the food system in the external environment.

Findings
The socio-ecological model is extended to examine how social marketers can influence the micro and macro environment through targeting the physical structure, economic, political and socio-cultural environment of desirable (sustainable) and undesirable (unsustainable) food products.

Practical implications
The authors highlight that social marketers should focus on the various ways the external environment at multiple levels can be targeted to produce systemic change.

Originality/value
This paper broadens the current macro-social marketing knowledge by providing a framework to analyse where and how change can be affected at the various levels of society.
Direct texturing for additive manufacturing: software support and build tests
Authors: Armillotta Antonio 
Published: January 2020

Purpose
This paper aims to investigate the feasibility of adding macro-textures to triangle meshes for additive manufacturing (AM) focusing on possible time and quality issues in both software processing and part fabrication.

Design/methodology/approach
A demonstrative software tool was developed to apply user-selected textures to existing meshes. The computational procedure is a three-dimensional extension of the solid texturing method used in computer graphics. The tool was tested for speed and quality of results, considering also the pre- and post-processing operations required. Some textured meshes were printed by different processes to test build speed and quality.

Findings
The tool can handle models with realistic complexity in acceptable computation times. Parts are built without difficulties or extra-costs achieving a good aesthetic yield of the texture.

Research limitations/implications
The tool cannot reproduce sample patterns but requires the development of a generation algorithm for different type of textures. Mesh processing operations may take a long time when very fine textures are added to large parts.

Practical implications
Direct texturing can help obtain parts with aesthetic or functional textures without the need for surface post-treatments, which can be especially difficult and expensive for plastic parts.

Originality/value
The proposed method improves the uniformity and consistency of textures compared to existing approaches, and can support future systematic studies on the detail resolution of AM processes.

Authors: Gupta Kanishk , Arora Nupur 
Published: January 2020

Purpose
The purpose of this paper is to examine the impact of key antecedents of unified theory of acceptance and use of technology model 2 on behavioral intention to accept and use mobile payment systems in National Capital Region, India.

Design/methodology/approach
A sample of 267 mobile payment system users in National Capital Region was obtained through an online survey. A partial least squares method was used to find out whether key antecedents of UTAUT2 predict behavioral intention to accept mobile payment systems which further predicts use behavior toward mobile payment systems.

Findings
The research substantiates that performance expectancy, effort expectancy, habit and facilitating conditions significantly predict behavioral intention, which in turn significantly predict use behavior to use mobile payment systems. Both social influence and hedonic motivation were weak predictors of behavioral intention.

Research limitations/implications
The research substantiates that performance expectancy, effort expectancy, habit and facilitating conditions significantly predict behavioral intention, which in turn significantly predict use behavior to use mobile payment systems. Both social influence and hedonic motivation were weak predictors of behavioral intention.

Originality/value
The research substantiates that performance expectancy, effort expectancy, habit and facilitating conditions significantly predict behavioral intention, which in turn significantly predict use behavior to use mobile payment systems. Both social influence and hedonic motivation were weak predictors of behavioral intention.
Does Ban on Futures trading (de)stabilise spot volatility?
Authors: Sobti Neharika 
Published: January 2020

Purpose
The purpose of this paper is to ascertain the possible consequences of ban on futures trading of agriculture commodities in India by examining three critical issues: first, the author explores whether price discovery dominance changes between futures and spot in the pre-ban and post-relaunch phase both in the long run and short run. Second, the author examines the impact of ban and relaunch of futures trading on its underlying spot volatility for five sample cases of agriculture commodities (Wheat, Sugar, Soya Refined Oil, Rubber and Chana) using both parametric and non-parametric tests. Third, the author revisits the destabilization hypothesis in the light of ban on futures trading by examining the impact of unexpected component of liquidity of futures on spot volatility.

Design/methodology/approach
The author uses widely adopted methodology of co-integration to examine long-run relationship between spot and futures, while the short-run relationship is investigated using vector error correction model (VECM) and Granger causality to test price discovery in the pre-ban and post-relaunch phases. The second objective is explored using a combination of parametric and non-parametric tests such as Welch one-way ANOVA and Kruskal–Wallis test, respectively, to gauge the impact of ban on futures trading on spot volatility along with post hoc tests to investigate pairwise comparison of spot volatility among three phases (pre-ban, ban and post-relaunch) using Dunn Test. In addition, extensive robustness test is undertaken by adopting augmented E-GARCH model to ascertain the impact of ban and relaunch of futures trading on spot volatility. The third objective is investigated using Granger causality test between spot volatility and unexpected component of liquidity of futures estimated using Hodrick and Prescott (HP) filter to re-visit the destabilization hypothesis.

Findings
The author found extensive evidence for the dominance of futures market in the price discovery of agriculture commodities both in the pre-ban and post-relaunch phases in India. The ban on futures trading is found to have a destabilizing impact on spot volatility as evident from the findings of Wheat, Sugar and Rubber. In addition, it is observed that spot volatility was highest during the ban phase as compared to the pre-ban and post-relaunch phases for all four commodities barring Chana. The author found that destabilisation hypothesis holds true during the pre ban phase, while weakening of destabilization hypothesis is observed in the post-relaunch phase as unexpected futures liquidity has no role in driving the spot volatility.

Originality/value
This study is a novel attempt to empirically examine the potential impact of ban and relaunch of futures trading of agriculture commodities on two key market quality dimensions – price discovery and spot volatility. In addition, destabilization hypothesis is revisited to investigate the impact of futures trading on spot volatility during the pre-ban and post-relaunch period.
Towards sustainable cities: about redundancy, voids and the potentials of the land
Authors: Roggema Rob 
Published: January 2020

PurposeWith future (extreme) change ahead of us, there are many serious problems humankind has to face. The pace of mitigating climate change through an energy transition to renewables is slow, global mean temperature is increasing and sea level seems to rise at an accelerated pace. This puts many livelihoods at risk and communities have to face an uncertain future. Therefore, continuing the way contemporary cities are developing and developed is not an option. The new normal should also be reflected in urbanism. The paper aims to discuss these issues.Design/methodology/approachIn this paper, the answer to this question is sought in understanding traditional attitudes to living and their relation to the land. How these cultures have been capable of coping with disruptions lies in the way their mental paradigm respects their environment. A more resilient future can be achieved when the traditional values of the relation of societies with the land they live on are considered important and indigenous knowledge and perspectives are used to design cities.FindingsCurrent society seems to have forgotten what it means and how to put into practice sharing resources and space, giving back more to the environment than used to live. Also, mankind seems to be lacking the ability to move and search for the potentials where to live. Furthermore, choosing to live in safe places, hence being less vulnerable for disruptions, is a principle that has long been neglected. These characteristics of traditional cultures are translated in four principles that are valuable in design processes: first, making use of the energy and power a disaster might bring and turning it into an advantage; second, using imagination to anticipate an unknown future; third, accommodating all paces of urban change; and fourth, designing redundancy for flexibility. The use of these principles is illustrated in three Sydney-based examples.Originality/valueThe link between indigenous knowledge and current urban design practice is new.

Published: January 2020

PurposeThe purpose of this paper is to examine the relative awareness and influence of stakeholders on sustainable residential property development in Lagos, Nigeria. This is with a view to identifying the key stakeholders pertinent to enhancing sustainable residential property development in the country.Design/methodology/approachData on awareness and influence of stakeholders on decisions to adopt sustainable residential property were elicited from residential property users, building contractors, property investors, estate surveyors and valuers and government regulatory agencies in Lagos residential property sector. The data were collected by using a questionnaire and analysed using mean item score and analysis of variance.FindingsThe result showed that the government regulatory agencies and the building professionals were aware of sustainable buildings, as mean scores measuring their awareness were higher than 2.5 on a scale of 1–5. The level of awareness of users was, however, low (mean score of 2.39). The users and the government regulatory agencies were identified by the stakeholders as being most influential on their decisions to adopt sustainable residential property.Practical implicationsFindings from this study indicate that there is need to promote the users and government regulatory agencies’ activities on sustainable residential property development as the activities of these stakeholders have higher influence on sustainable residential property development decisions in the study area.Originality/valueThis study particularly examines the interrelationships between the activities of stakeholders in sustainable residential property development in Nigeria. This has not been adequately studied in extant literature.
Performance of liquid–liquid hydrocyclone (LLHC) for treating produced water from surfactant flooding produced water
Authors: Ku Ishak Ku Esyra Hani , Abdalla Ayoub Mohammed 
Published: January 2020

PurposeThe purpose of this study is to investigate the performance of the fabricated liquid–liquid hydrocyclone (LLHC) with dimensions similar to those of one of the Malaysian oilfields with the presence of an anionic surfactant, S672. The effect of salinity and initial oil concentration were also investigated following the actual range concentration.Design/methodology/approachThe current control system’s pressure drop ratio (PDR) does not necessarily lead to an efficient LLHC. Therefore, rather than using the PDR, the efficiency of the LLHC was analyzed by comparing the concentration of oil in the effluents with the concentration of oil at the feed of the LLHC. An LLHC test rig was developed at Centre of Enhanced Oil Recovery, Universiti Teknologi PETRONAS. Emulsions were prepared by mixing the brines, S672 and oil by using Ultra Turrax ultrasonic mixer. The emulsion was pumped into the LLHC at different feed flowrate and split ratio. The brines concentration, initial oil concentration and S672 concentration were also varied in this study. Samples were taken at the underflow of the LLHC and the oil in water concentration analysis was done for the samples using TD-500D equipment.FindingsIt was found that the efficiency of oil removal decreased with an increase in S672 concentration but increased with the increase in salinity and initial oil concentration.Originality/valueThe optimum feed flowrate for the LLHC of 45 mm diameter and length of 1,125 mm with the presence of S672 surfactant was found to be 40 L/min with a split ratio of 14%. This study can be used as a guidance for future optimization of the LLHC in the presence of the surfactant.
