Abstract

Purpose

The present research study aims to explore the impact of renewable energy (RE) on investors willing to invest. This current study also investigates the mediation role of perceived benefit (PB) and living creature’s development (LCD) among RE and investors willing to invest.

Design/methodology/approach

Pakistani per capita income level is low; usually, the population lives hand to mouth. Only 10% to 15% of the population has been saving and is willing to invest in different sectors. To meet the aim of this study, data were collected from 300 individuals with a 40% response rate investors, equity fund managers and Pakistani stock exchanges using a nonprobability convenient sampling approach. The partial least square structural equation modeling technique and Smart partial least squares 3.0 were used to determine the primary and medicating effects of the variables.

Findings

The analysis shows that RE and investor willing to invest strongly linked each other directly and indirectly. PB and LCD significantly partial mediate the connection among RE and investor willing to invest. Hence, the results suggest that RE has more sustainable development goals with using and accessing affordable green and reliable energy.

Originality/value

The present study narrows the research gap by examining the effect of RE on investor willing to invest via PB and LCD. Also, it provides essential information for effective energy policies contributed to the sustainable development goals and gives valuable suggestions for policymaker and government.

Abstract

As a growing literature points out (Aronowitz, 2009, pp. 165–213), HT becomes criminal because it involves displacing, exploiting and commercializing a human being, all of these necessitating transportation, trade and torture to varying degrees to survive and succeed (Nair, 2010, pp. 12–19). John T. Picarelli informs us, these began ‘in the Americas’ from 1502, ‘when Portuguese traders brought the first African slaves to the Caribbean’ (Picarelli, 2011, p. 180, but see all of Chapter 9). African slaves continued to be imported into the United States until 1808, but by the time the 13th Amendment ‘outlawed’ indentured servitude in 1865, the 645,000 slaves shipped from Africa had multiplied beyond 4 million, to whom were added (a) Chinese women, ‘to work in brothels … to serve both the Chinese and white communities’ after the 1860s; (b) Europeans, through collusion between ‘criminal syndicates’ and ‘U.S. [law enforcement] officials’, in what was called ‘the white slave trade’ from the 1880s (Shelley, 2010, pp. 235, 237); and (c) Hispanics (Alba & Nee, 2003; Gordon, 1964; Suárez-Orozco, 1998), in tandem with the dominant U.S. migratory inflows and economic needs after the 1960s (Borjas, 1999; Huntington, 2004, pp. 30–45), and the emergence of sex tourism after the Cold War (Clift & Carter, 2000; María Agustin, 2007; Rogers, 2009; Thorbek & Bandana Pattanaik, 2002).

Abstract

Meng-Hsuan Chou starts the anthology with Chapter 2, ‘EU Mobility Partnerships and Gender: Origin and Implications’. Here she shows how current EU regulations regarding migration came to be formed they way they are and how this development was motivated. She not only explores the circumstances under which European Union (EU) mobility partnerships were established, but also examines the effects in terms of migration flows. She raises the question of how the migration policies of the receiving states gender migratory flows, and also wonder whether instrument formulations are intentional or unintentional. While previous research has mostly examined these issues from the perspective of national migration policies, Chou finds that a supranational viewpoint still is missing, a gap in the literature she here aims to fill in. The EU migration instruments known as the ‘mobility partnerships’ are established by participating EU member states and certain third-world countries with the aim of facilitating circular migration. Chou approaches her questions through empirical analysis of three different data sets: (1) existing studies on the migration-development nexus, European migration policy co-operation and EU mobility partnerships; (2) publicly available reports and official EU documents and (3) position papers circulated amongst national delegates who prepared for, and defended their domestic positions at, the Tampere European Council summit. She suggests that the European governments rarely had ‘gender balance’ as priority when it came to border control. However, by definition and design, EU policies are meant to affect migratory flows. To discern how, it is necessary to look more closely at what happens in practice when member states implement the measures (e.g. from the EU level to the national/bilateral level).

Abstract

Purpose

The basic intention of this research is to investigate the role of information transparency of financial institutions and psychological attitude of the individuals toward their attention to saving and borrowing. This study also tries to know how an individual's psychological factor affects a person's attitude to motivate them to save or borrow and contribute to well-being by giving them confidence that they can face financial challenges. So, the main concern of this study is to explore different factors that ultimately contribute to the financial well-being (FWB) of individual.

Design/methodology/approach

A survey was conducted by using a well-structured questionnaire to collect data and test the developed hypotheses by using SmartPLS. Data were collected from 120 customers of seven different commercial banks in Pakistan.

Findings

The findings of this study show that perceived information transparency positively affects FWB. It is also because transparent shared information creates positive change in individuals' perceived self-efficacy and leads to FWB. Furthermore, an individual's psychological attitude toward borrowing and saving did not contribute to the FWB of people who belong to Pakistan.

Research limitations/implications

The research area is limited to one city of Pakistan and analysis is done with small numbers of sample, it can be increased and more areas can be explored.

Practical implications

This research provides significant implications for people and economists by providing awareness about the antecedents of FWB. The policymakers or managers who work in financial institutions should provide more transparent information and create less risky opportunities to improve the individual's well-being. If person, manager and financial institution can properly utilize the information of this study, then they are able to improve their FWB. By providing more transparent services and favorable experience with your dealings, it could help to obtain and retain more loyal internal (employees) and external customers. The loyal customers and sincere employees can increase the productivity level of organization. The more productive organizations in countries means better society and progress in the economy.

Originality/value

This research contributes to the body of knowledge that how perceived information transparency and psychological attitude of borrowing create improvement and upward changes in the FWB of a person.

Abstract

Purpose

Authenticating an individual through voice can prove convenient as nothing needs to be stored and cannot easily be stolen. However, if an individual is authenticating under duress, the coerced attempt must be acknowledged and appropriate warnings issued. Furthermore, as duress may entail multiple combinations of emotions, the current f-score evaluation does not accommodate that multiple selected samples possess similar levels of importance. Thus, this study aims to demonstrate an approach to identifying duress within a voice-based authentication system.

Design/methodology/approach

Measuring the value that a classifier presents is often done using an f-score. However, the f-score does not effectively portray the proposed value when multiple classes could be grouped as one. The f-score also does not provide any information when numerous classes are often incorrectly identified as the other. Therefore, the proposed approach uses the confusion matrix, aggregates the select classes into another matrix and calculates a more precise representation of the selected classifier’s value. The utility of the proposed approach is demonstrated through multiple tests and is conducted as follows. The initial tests’ value is presented by an f-score, which does not value the individual emotions. The lack of value is then remedied with further tests, which include a confusion matrix. Final tests are then conducted that aggregate selected emotions within the confusion matrix to present a more precise utility value.

Findings

Two tests within the set of experiments achieved an f-score difference of 1%, indicating, Mel frequency cepstral coefficient, emotion detection, confusion matrix, multi-layer perceptron, Ryerson audio-visual database of emotional speech and song (RAVDESS), voice authentication that the two tests provided similar value. The confusion matrix used to calculate the f-score indicated that some emotions are often confused, which could all be considered closely related. Although the f-score can represent an accuracy value, these tests’ value is not accurately portrayed when not considering often confused emotions. Deciding which approach to take based on the f-score did not prove beneficial as it did not address the confused emotions. When aggregating the confusion matrix of these two tests based on selected emotions, the newly calculated utility value demonstrated a difference of 4%, indicating that the two tests may not provide a similar value as previously indicated.

Research limitations/implications

This approach’s performance is dependent on the data presented to it. If the classifier is presented with incomplete or degraded data, the results obtained from the classifier will reflect that. Additionally, the grouping of emotions is not based on psychological evidence, and this was purely done to demonstrate the implementation of an aggregated confusion matrix.

Originality/value

The f-score offers a value that represents the classifiers’ ability to classify a class correctly. This paper demonstrates that aggregating a confusion matrix could provide more value than a single f-score in the context of classifying an emotion that could consist of a combination of emotions. This approach can similarly be applied to different combinations of classifiers for the desired effect of extracting a more accurate performance value that a selected classifier presents.

Abstract

Purpose

The purpose of this paper is to explore the novel aspects of activation energy in the nonlinearly convective flow of Walter-B nanofluid in view of Cattaneo–Christov double-diffusion model over a permeable stretched sheet. Features of nonlinear thermal radiation, dual stratification, non-uniform heat generation/absorption, MHD and binary chemical reaction are also evaluated for present flow problem. Walter-B nanomaterial model is employed to describe the significant slip mechanism of Brownian and thermophoresis diffusions. Generalized Fourier’s and Fick’s laws are examined through Cattaneo–Christov double-diffusion model. Modified Arrhenius formula for activation energy is also implemented.

Design/methodology/approach

Several techniques are employed for solving nonlinear differential equations. The authors have used a homotopy technique (HAM) for our nonlinear problem to get convergent solutions. The homotopy analysis method (HAM) is a semi-analytical technique to solve nonlinear coupled ordinary/partial differential equations. The capability of the HAM to naturally display convergence of the series solution is unusual in analytical and semi-analytic approaches to nonlinear partial differential equations. This analytical method has the following great advantages over other techniques:

  • It provides a series solution without depending upon small/large physical parameters and applicable for not only weakly but also strongly nonlinear problems.

  • It guarantees the convergence of series solutions for nonlinear problems.

  • It provides us a great choice to select the base function of the required solution and the corresponding auxiliary linear operator of the homotopy.

It provides a series solution without depending upon small/large physical parameters and applicable for not only weakly but also strongly nonlinear problems.

It guarantees the convergence of series solutions for nonlinear problems.

It provides us a great choice to select the base function of the required solution and the corresponding auxiliary linear operator of the homotopy.

Brief mathematical description of HAM technique (Liao, 2012; Mabood et al., 2016) is as follows. For a general nonlinear equation:

(1) N [ u ( x ) ] = 0 ,

where N denotes a nonlinear operator, x the independent variables and u(x) is an unknown function, respectively. By means of generalizing the traditional homotopy method, Liao (1992) creates the so-called zero-order deformation equation:

(2) ( 1 q ) L [ u ˆ ( x ; q ) u o ( x ) ] = q h H ( x ) N [ u ˆ ( x ; q ) ] ,

here q∈[0, 1] is the embedding parameter, H(x) ≠ 0 is an auxiliary function, h(≠ 0) is a nonzero parameter, L is an auxiliary linear operator, uo(x) is an initial guess of u(x) and u ˆ ( x ; q ) is an unknown function, respectively. It is significant that one has great freedom to choose auxiliary things in HAM. Noticeably, when q=0 and q=1, following holds:

(3) u ˆ ( x ; 0 ) = u o ( x ) and u ˆ ( x ; 1 ) = u ( x ) ,

Expanding u ˆ ( x ; q ) in Taylor series with respect to (q), we have:

(4) u ˆ ( x ; q ) = u o ( x ) + m = 1 u m ( x ) q m , where u m ( x ) = 1 m ! m u ˆ ( x ; q ) q m | q = 0 .

If the initial guess, the auxiliary linear operator, the auxiliary h and the auxiliary function are selected properly, then the series (4) converges at q=1, then we have:

(5) u ( x ) = u o ( x ) + m = 1 + u m ( x ) .

By defining a vector u = ( u o ( x ) , u 1 ( x ) , u 2 ( x ) , , u n ( x ) ) , and differentiating Equation (2) m-times with respect to (q) and then setting q=0, we obtain the mth-order deformation equation:

(6) L [ u ˆ m ( x ) χ m u m 1 ( x ) ] = h H ( x ) R m [ u m 1 ] ,

where:

(7) R m [ u m 1 ] = 1 ( m 1 ) ! m 1 N [ u ( x ; q ) ] q m 1 | q = 0 and χ m = | 0 m 1 1 m > 1 .

Applying L−1 on both sides of Equation (6), we get:

(8) u m ( x ) = χ m u m 1 ( x ) + h L 1 [ H ( x ) R m [ u m 1 ] ] .

In this way, we obtain um for m ⩾ 1, at mth-order, we have:

(9) u ( x ) = m = 1 M u m ( x ) .

Findings

It is evident from obtained results that the nanoparticle concentration field is directly proportional to the chemical reaction with activation energy. Additionally, both temperature and concentration distributions are declining functions of thermal and solutal stratification parameters (P1) and (P2), respectively. Moreover, temperature Θ(Ω1) enhances for greater values of Brownian motion parameter (Nb), non-uniform heat source/sink parameter (B1) and thermophoresis factor (Nt). Reverse behavior of concentration ϒ(Ω1) field is remarked in view of (Nb) and (Nt). Graphs and tables are also constructed to analyze the effect of different flow parameters on skin friction coefficient, local Nusselt number, Sherwood numbers, velocity, temperature and concentration fields.

Originality/value

The novelty of the present problem is to inspect the Arrhenius activation energy phenomena for viscoelastic Walter-B nanofluid model with additional features of nonlinear thermal radiation, non-uniform heat generation/absorption, nonlinear mixed convection, thermal and solutal stratification. The novel aspect of binary chemical reaction is analyzed to characterize the impact of activation energy in the presence of Cattaneo–Christov double-diffusion model. The mathematical model of Buongiorno is employed to incorporate Brownian motion and thermophoresis effects due to nanoparticles.

Abstract

Purpose

This study aims to assess the quality of care among adult oncology patients in tertiary care hospitals in Karachi by using an international standard of quality of care and to identify domains where improvement is needed.

Design/methodology/approach

This is a cross-sectional study carried out at two tertiary care hospitals of Karachi, Pakistan, belonging to private and public sector, respectively, between February and April 2018. Face-to-face interviews were conducted using a modified questionnaire having five-point Likert scale questions regarding satisfaction of patients with doctors, nursing staff, information provided and the hospital standards. SPSS 20 was used for statistical analysis, and the results were expressed using mean, frequencies, percentages and p-values.

Findings

The authors approached 415 patients, out of which 389 patients agreed to participate in the study. For both hospitals, the lowest mean scores were for sections pertaining to satisfaction with psychosocial support and information provided. The mean satisfaction score of patients from the private hospital were found to be significantly higher as compared to patients from the public hospital for all domains of patient care (p-value < 0.01 using t-test for two independent samples). The data showed an increasing trend of “satisfied” responses as the household income increased.

Research limitations/implications

A comparative study should be conducted with the aim of pinpointing the differences in areas in which there is a significant difference in positive satisfaction levels between private and public sectors. Similar research could also be expanded adding other variables that affect quality of care such as doctor's approach to their patients, time given during each consultation and patient's understanding of doctor's knowledge. Further studies can be done to bridge the gaps between what a doctor views as standard care and what the patient knows will help them receive a more holistic approach to care.

Practical implications

Assessing the quality of care helps determine gaps in care and allocating health resources accordingly. In clinical practice, emphasis needs to be given on increased duration and improved quality of patient counselling to improve the low satisfaction levels of patients regarding the psychosocial support. Addressing patients' concerns should be made part of clinical teaching from an undergraduate level. As far as patient access to doctors of the specific speciality is concerned, hospital managements should adopt systems to ensure continuum of care and come up with mechanisms to bridge the discrepancy between a patient's needs and doctor availability.

Social implications

After being identified as a major deficiency, training doctors in the sensitivities of the population and demographics, especially with respect to socio-economic statuses, can aid in enhancing patient satisfaction to the treatment. Implementation of patient-centred care leads to greater satisfaction with care, which, in turn, increases a patient's self efficacy in managing important aspects of their care and improves health care-related quality of life.

Originality/value

Cancer patients have long-term exposure to the hospital environment. A patient's satisfaction with the quality of care is an important determinant in patient compliance to the treatment protocol and required hospital visits. There is a dearth of research on the outpatient quality of care in the oncology departments in Karachi. This study provides an overview of the quality of care available to cancer patients in Karachi both in public and private sectors. The results of our study identify the gaps in the quality of care being provided to the patients in a developing country like Pakistan, which can be used to improve the quality of care, leading to better patient outcomes.
