The purpose of this paper is to study numerically the influence of a magnetic field on the transient free convective boundary layer flow of a nanofluid over a moving semi-infinite vertical cylinder with heat transfer

The problem is governed by the coupled non-linear partial differential equations with appropriate boundary conditions. The fluid is a water-based nanofluid containing nanoparticles of copper. The Brinkman model for dynamic viscosity and Maxwell–Garnett model for thermal conductivity are used. The governing boundary layer equations are written according to The Tiwari–Das nanofluid model. A robust, well-tested, implicit finite difference method of Crank–Nicolson type, which is unconditionally stable and convergent, is used to find the numerical solutions of the problem. The velocity and temperature profiles are studied for significant physical parameters such as the magnetic parameter, nanoparticles volume fraction and the thermal Grashof number Gr. The local skin-friction coefficient and the Nusselt number are also analysed and presented graphically.

The present computations have shown that an increase in the values of either magnetic parameter M or nanoparticle volume fraction decreases the local skin-friction coefficient, whereas the opposite effect is observed for thermal Grashof number Gr. The local Nusselt number increases with a rise in Gr and ϕ values. But an increase in M reduces the local Nusselt number.

This paper is relatively original and presents numerical investigation of transient two-dimensional laminar boundary layer free convective flow of a nanofluid over a moving semi-infinite vertical cylinder in the presence of an applied magnetic field. The present study is of immediate application to all those processes which are highly affected by heat enhancement concept and a magnetic field. Further the present study is relevant to nanofluid materials processing, chemical engineering coating operations exploiting nanomaterials and others.

The physical, biomechanical and chemical properties of the composite biodegradable films are examined by their chemical composition, structure, processing conditions and economics. Therefore, the purpose of the study was to develop standard composite biodegradable films by optimizing the process (drying time and temperature) and composition (whey protein concentrate; WPC and sodium alginate; SA).

Composite WPC–SA films were developed using the Box–Behnken design of response surface methodology (RSM), with individual and interactive effects of process variables on the response variables (quality characteristics). Three independent factors at three different levels (WPC: 5–7 g, SA: 0.1–0.5 g and drying temperature: 35°C–45°C) were evaluated for their effects on physical and biomechanical properties, namely, thickness, penetrability, moisture content, water vapor transmission rate (WVTR), density, solubility, transmittance and color variables. The results were analyzed using ANOVA. For each response, second-order polynomial regression models and resulting equations were developed.

The response surface plots were constructed for representing a relationship between process parameters and responses. All responses were optimized as the best and desired, namely, thickness (180 µm), penetrability (7.63 N), moisture (28.05%), WVTR (1.87 mg/m²t), solubility (36.12%), density (1.33 g/ml), transmittance (40.55%), L* value (52.50), a* value (0.35) and b* value (13.70). The regression models exhibited “good fit” of experimental data with a high coefficient of determination. A close agreement was found between experimental and predicted values.

These biodegradable films can be promisingly used in the food packaging system without the problem of disposability.

The composite films with proteins and polysaccharides can be developed, which have improved physical and biomechanical properties.

The purpose of this paper is to consider unsteady free convection flow of a dissipative fluid past an exponentially accelerated infinite vertical porous plate in the presence of Newtonian heating and mass diffusion.

The problem is governed by coupled non-linear partial differential equations with appropriate boundary conditions. A Galerkin finite element numerical solution is developed to solve the resulting well-posed two-point boundary value problem. It is a powerful, stable technique which provides excellent convergence and versatility in accommodating coupled systems of ordinary and partial differential equations.

It is found that the skin friction coefficient increases with increases in either of the Eckert number, thermal Grashof number, mass Grashof number or time whereas it decreases with increases in either of the suction parameter, Schmidt number or the acceleration parameter for both air and water. The skin friction coefficient is also found to decrease with increases in the values of the Prandtl number. In addition, it is found that the rate of heat transfer increases with an increase in the suction parameter and decreases with an increase in the Eckert number for both air and water. Lastly, it is found that the rate of heat transfer increases with increasing values of the Prandtl number and decreases with increasing time for all values of the Prandtl number.

The present study has considered only Newtonian fluids. Future studies will address non-Newtonian liquids.

A very useful source of information for researchers on the subject of free convective flow over the surface when the rate of heat transfer from the surface is proportional to the local surface temperature.

This paper is relatively original and illustrates the effects of viscous dissipation on free convective flow past an exponentially accelerated infinite vertical porous plate with Newtonian heating and mass diffusion.

This paper aims to report a research approach that explores how to use evaluations of previous social marketing efforts to assess and guide a new shelterbelt program called Working Tree. By targeting farmers, this new program aims to gain benefits from enhancing and expanding on-farm tree shelterbelts on the Canadian prairies.

This paper uses a novel method that relies on secondary data from six completed social marketing cases as data for a comparative analysis with the new program. A conceptual framework is proposed and applied. This framework incorporates process and outcome indicators of evaluation, key dimensions of the rational choice theory and proven practices from experience.

Analysis suggests key parameters of the Working Tree program to be appropriate, with some modifications. However, limitations in the data also point to avenues for future research to deepen the authors’ understanding of assessing a new social marketing program in the prelaunch phase. More research is needed on what works, where and why.

The seven indices are a modest set for comparatives and are not exhaustive. Six selected cases are small samples that are unable to fully reflect the environmental nature of the new program; yet, they contained critical data for the comparative analysis. Financial data are not in constant dollars, which would be needed when further analysis is undertaken.

This paper illustrates the importance of the evaluation stage of the social marketing process. It demonstrates the practicality of being able to effectively draw upon previous evaluations to inform new program investors and social marketers at the prelaunch stage.

The conceptual framework and method present a novel approach to use evaluation data to guide new program funding and initiatives. It is offered with the hope that others might draw upon the ideas presented here and advance them.

This study aims to develop and test a new formative theory of coping intelligence (CI). It asserts that problem- and emotion-focused coping strategies contribute differently to the overall CI latent construct, which, in turn, relates to three outcome variables – job satisfaction, life satisfaction and sales commission.

The study collected data from multiple sources: survey data from 452 boundary-spanning salespeople and sales commission from a company’s personnel record. It then investigated the goodness of fit between the study’s theoretical SEM model and empirical data.

Problem-focused coping and emotion-focused coping strategies, respectively, define CI positively and negatively. This, in turn, is related to high levels of job satisfaction, life satisfaction and sales commission. After controlling for gender and sales commission, results remain significant. Commission is related to satisfaction. Gender (male) is negatively related to emotion-focused strategy, but positively related to commission. Males have higher sales commission than females, yet both genders have similar life and job satisfaction.

Problem-focused coping contributes to life satisfaction, job satisfaction and sales commission, but emotion-focused coping undermines them. Researchers and policymakers need to develop training programs, promote problem-focused coping strategies and help them improve life satisfaction, job satisfaction and sales commission, for females, in particular.

CI is more related to job satisfaction and life satisfaction than to commission. The study’s concurrent validity demonstrates that CI improves sales commission (objective data) and employee satisfaction. It pays to improve CI.

In an ongoing War for Talent, what are the intangible and tangible return on investments (ROIs) for boundary-spanning employees? This study aims to develop a formative structural equation model (SEM) of the Matthew effect in talent. management.

This study develops a formative SEM theoretical model. Training and development (T&D) are the two antecedents of the latent construct – talent management strategy (TMS). This study frames the latent construct (TMS) in the proximal context of reducing burnout (cynicism and inefficacy), the distal context of subjective and intangible outcomes (job and life satisfaction) and the omnibus context of objective, tangible and financial rewards (the sales commission). The study collected data from multiple sources – objective sales commission from personnel records and subjective survey data from 512 sales employees.

The empirical discoveries support the theory. Both T&D contribute significantly to the TMS, which reduces burnout in the immediate context. TMS enhances job satisfaction more than life satisfaction in the distal context. TMS significantly and indirectly improves boundary spanners’ sales commission in the omnibus context via life satisfaction, but not job satisfaction. The model prevails for the whole sample, men, but not women.

Our discoveries offer practical implications for the Matthew effect in talent management: policymakers must cultivate T&D, develop TMS, facilitate the spillover effect from job satisfaction to life satisfaction, concentrate on the meaning in their lives and take their mind off money. TMS ultimately helps ignite these boundary spanners’ sales commission and their organization’s bottom line and financial health. The rich get richer.

It is life satisfaction (not job satisfaction) that excites boundary-spanning employees’ high level of sales commission. Our model prevails for the whole sample and men, but not for women. Job satisfaction spills over to life satisfaction for the entire sample, for men, but not for women. The results reveal gender differences.

This paper aims to highlight the candidature of papaya/Carica papaya L. extracts (PLE) and oregano/Origanum vulgare leaves extract (OLE) as novel natural antioxidants, which was further fortified into goat meat nuggets to evaluate quality changes and storage stability at refrigeration temperature (4 ± 1ºC) for 20 days.

Three different products, namely, control (without phyto-extracts), T−1: PLE (0.5 per cent) and T-2: OLE (1.0 per cent) fortified goat meat nuggets, were prepared and subjected for various quality attributes with relation to storage stability.

It was observed that pH significantly (p = 0.14) decreased till 10th day of storage i.e. from 6.49 to 6.32 (control), 6.37 to 6.28 (T−1) and 6.45 to 6.43 (T-2) afterword showed increasing trend till further storage of 20 days in control, as well as treated products. Water activity was non-significant (p = 0.01) on first day of storage and decreased up to 20th day. PLE treated product showed good margin of microbiological protection followed by OLE and least was found in control. L* value showed increasing trend (p = 0.03) throughout storage and ranged from 50.15 to 54.27, while a* values were decreased significantly from 10.36 to 9.06, 10.86 to 9.49 in PLE (p = 0.02) and OLE (p = 0.03), respectively. Sensory panel awarded the highest score for fortified goat meat nuggets, justifying the best quality attributes in term of texture attributes of the treated products. Thus, papaya and oregano leave extracts proved in the extension of shelf life and can be further harvested to develop functional goat meat nuggets.

In search of novel bioactive phyto-extract, meat industry focussed most of the research towards natural anti-oxidants. In the view of same, the present research strategy was planned to examine candidature of Carica papaya L. and OLEs as novel natural antioxidant into meat system during aerobic packaging storage. Goat meat nuggets are amongst the most convenient and famous snack, as well as nutritious meat products, but lacks functional properties. Therefore, with implication of present research at practical level, meat industry can develop function goat meat nuggets by incorporating Carica papaya L. and Origanum vulgare extracts as natural and novel bioactive antioxidants with improved functionality.

This is the first attempt to develop functional goat meat nuggets incorporated with papaya/Carica papaya L. and oregano/OLE. This research can lead to be a pioneer work in meat science.

This study aims to examine the impact of stress as a result of adverse life events on a salesperson’s ability to effectively manage customer relationships. The framework identifies burnout as a key mediating variable and salesperson grit as a coping mechanism.

Survey data is gathered from 364 B2B salespeople and investigated using structural equation modeling in Mplus 8.2.

The findings reveal adverse life events and their corresponding stress diminish a salesperson’s ability to manage customer relationships effectively through the mediators of reduced personal accomplishment and depersonalization. Thus, negative events of a personal nature can have a significant impact on salesperson outcomes and should be taken with the same level of seriousness as job-related stress. Furthermore, results show that salesperson grit provides mixed results as a coping mechanism.

The findings indicate that practitioners should be mindful of the negative impact adverse life events can have on work-related outcomes. Organizations and sales managers must be intentional in managing relationships with their salespeople and strategic in the structure they use to manage customer relationships. Recommendations include the use of regular one-on-one meetings to open up a dialogue about work or personal issues the salesperson is experiencing and assigning multiple resources or staff to service valuable customers, thereby not relying on solitary salespeople.

Employee well-being contributes to firm value; yet, this is the first study in sales to explore the impact of adverse life events on salesperson outcomes.

The purpose of this paper is to focus on the numerical modelling of transient natural convection flow of an incompressible viscous nanofluid past an impulsively started semi-infinite vertical plate with variable surface temperature.

The problem is governed by the coupled non-linear partial differential equations with appropriate boundary conditions. A robust, well-tested, Crank-Nicolson type of implicit finite-difference method, which is unconditionally stable and convergent, is used to solve the governing non-linear set of partial differential equations.

The local and average values of the skin-friction coefficient (viscous drag) and the average Nusselt number (the rate of heat transfer) decreased, while the local Nusselt number increased for all nanofluids, namely, aluminium oxide-water, copper-water, titanium oxide-water and silver-water with an increase in the temperature exponent m. Selecting aluminium oxide as the dispersing nanoparticles leads to the maximum average Nusselt number (the rate of heat transfer), while choosing silver as the dispersing nanoparticles leads to the minimum local Nusselt number compared to the other nanofluids for all values of the temperature exponent m. Also, choosing silver as the dispersing nanoparticles leads to the minimum skin-friction coefficient (viscous drag), while selecting aluminium oxide as the dispersing nanoparticles leads to the maximum skin-friction coefficient (viscous drag) for all values of the temperature exponent m.

The Brinkman model for dynamic viscosity and Maxwell-Garnett model for thermal conductivity are employed. The governing boundary layer equations are written according to The Tiwari-Das nanofluid model. A range of nanofluids containing nanoparticles of aluminium oxide, copper, titanium oxide and silver with nanoparticle volume fraction range less than or equal to 0.04 are considered.

The present simulations are relevant to nanomaterials thermal flow processing in the chemical engineering and metallurgy industries. This study also provides an important benchmark for further simulations of nanofluid dynamic transport phenomena of relevance to materials processing, with alternative computational algorithms (e.g. finite element methods).

This paper is relatively original and illustrates the influence of variable surface temperature on transient natural convection flow of a viscous incompressible nanofluid and heat transfer from an impulsively started semi-infinite vertical plate.

In the last 10 years, India has amended its laws dealing with sexual offences against women with the changes ranging from increasing terms of imprisonment for the offence of rape to state-funded compensation schemes for women and child victims. In this regard, challenges persist for the agencies of the criminal justice system in India especially the courts to realise the vision of restorative justice as these forums have to navigate the relevant statutory provisions and binding precedents. This chapter seeks to analyse the challenges faced by courts in proper reintegration of victims and offenders of sexual offences, the institutional responses of the courts and suggests reforms to the criminal justice system in India in consonance with the principles of restorative justice acknowledged in the restorative justice movement in the international discourse.
