The purpose of this study is to analyze an unsteady MHD Darcy flow of nonNewtonian hybrid nanoliquid past an exponentially accelerated vertical plate under the influence of velocity slip, Hall and ion slip effects in a rotating frame of reference. The fluids in the flow domain are assumed to be viscously incompressible electrically conducting. Sodium alginate (SA) has been taken as a base Casson liquid. A strong uniform magnetic field is applied under the assumption of low magnetic Reynolds number. Effect of Hall and ion-slip currents on the flow field is examined. The ramped heating and time-varying concentration at the plate are taken into consideration. First-order homogeneous chemical reaction and heat absorption are also considered. Copper and alumina nanoparticles are dispersed in base fluid sodium alginate to be formed as hybrid nanoliquid.

The model problem is first formulated in terms of partial differential equations (PDEs) with physical conditions. Laplace transform method (LTM) is used on the nondimensional governing equations for their closed-form solution. Based on these results, expressions for nondimensional shear stresses, rate of heat and mass transfer are also determined. Graphical presentations are chalked out to inspect the impacts of physical parameters on the pertinent physical flow characteristics. Numerical values of the shear stresses, rate of heat and mass transfer at the plate are tabulated for various physical parameters.

Numerical exploration reveals that a significant increase in the secondary flow (i.e. crossflow) near the plate is guaranteed with an augmenting in Hall parameter or ion slip parameter. MHD and porosity have an opposite effect on velocity component profiles for both types of nanoliquids. Result addresses that both shear stresses are strongly enhanced by the Casson effect. Also, hybrid nanosuspension in Casson fluid (sodium alginate) exhibits a lower rate of heat transfer than usual nanoliquid.

This model may be pertinent in cooling processes of metallic infinite plate in bath and hybrid magnetohydrodynamic (MHD) generators, metallurgical process, manufacturing dynamics of nanopolymers, magnetic field control of material processing, synthesis of smart polymers, making of paper and polyethylene, casting of metals, etc.

The originality of this study is to obtain an analytical solution of the modeled problem by using the Laplace transform method (LTM). Such an exact solution of nonNewtonian fluid flow, heat and mass transfer is rare in the literature. It is also worth remarking that the influence of Hall and ion slip effects on the flow of nonNewtonian hybrid nanoliquid is still an open question.

The wine industry is a multi‐billion product value category worldwide with a significant part being sales through hospitality service providers. Although wine sales add considerably to the profitability of many restaurants, hotels, bars and other hospitality establishments, few studies have been conducted into wine purchasing behaviour within hospitality settings. This study identifies the factors that influence consumers to purchase wine and attempts to demonstrate how the basic demographic characteristic of age is a useful variable for segmentation purposes. The study reveals that there are six dominant factors that influence wine purchasing behaviour and that significant differences in purchase motivation exist between three age segments, 18 to 25 years, 26 to 34 years and 34+years. The results of this research have significant implications for hospitality operators who, with a basic knowledge of the demographic characteristics of their guests, can develop marketing strategies to maximise the sale of wine and wine products.

The paper covers work done at Salford University and identifies those aspects of tribology which are important to both the design of metal working machines and to the tool/workpiece interaction. After identifying the important tribological problem areas some examples of possible methods of solution are indicated using the work at Salford University for typical examples. Inevitably the paper identifies many questions to which there are currently very limited answers and thereby indicates the areas for further research. It should however be stressed that the author does not claim to have produced a comprehensive review on tribology in manufacturing engineering. Rather the style of the paper is to question the way forward and in some cases even to propose answers.

Researchers conducted a qualitative analysis of students’ experiences while enrolled in an interdisciplinary leadership minor with the intent to determine programmatic inputs that spur leadership development. Based on students’ reflections, three domains of programmatic inputs for leadership development within the minor were identified. These domains include leadership development at the individual level, leadership development at the group level, and leadership development through experiential learning. Themes within these three domains are also identified providing additional insight into the participants’ experiences while enrolled in the leadership minor. Based on these findings, researchers proposed a framework for leadership development within an interdisciplinary minor. Recommendations for future research and application of the proposed framework are discussed.

The institution of food and cookery exhibitions and the dissemination of practical knowledge with respect to cookery by means of lectures and demonstrations are excellent things in their way. But while it is important that better and more scientific attention should be generally given to the preparation of food for the table, it must be admitted to be at least equally important to insure that the food before it comes into the hands of the expert cook shall be free from adulteration, and as far as possible from impurity,—that it should be, in fact, of the quality expected. Protection up to a certain point and in certain directions is afforded to the consumer by penal enactments, and hitherto the general public have been disposed to believe that those enactments are in their nature and in their application such as to guarantee a fairly general supply of articles of tolerable quality. The adulteration laws, however, while absolutely necessary for the purpose of holding many forms of fraud in check, and particularly for keeping them within certain bounds, cannot afford any guarantees of superior, or even of good, quality. Except in rare instances, even those who control the supply of articles of food to large public and private establishments fail to take steps to assure themselves that the nature and quality of the goods supplied to them are what they are represented to be. The sophisticator and adulterator are always with us. The temptations to undersell and to misrepresent seem to be so strong that firms and individuals from whom far better things might reasonably be expected fall away from the right path with deplorable facility, and seek to save themselves, should they by chance be brought to book, by forms of quibbling and wriggling which are in themselves sufficient to show the moral rottenness which can be brought about by an insatiable lust for gain. There is, unfortunately, cheating to be met with at every turn, and it behoves at least those who control the purchase and the cooking of food on the large scale to do what they can to insure the supply to them of articles which have not been tampered with, and which are in all respects of proper quality, both by insisting on being furnished with sufficiently authoritative guarantees by the vendors, and by themselves causing the application of reasonably frequent scientific checks upon the quality of the goods.

The Table which is printed along with this article gives a view of the progress of our Public Libraries as shown by the adoptions of the Acts, year by year, since 1848. In heavier type are set out the various Acts of Parliament or other influences which have had a determining effect in popularizing and spreading the Public Library. We have also added as an item of additional interest, the name of the first librarian of each town, so far as we have been able to ascertain it. But this is not guaranteed to be absolutely correct, and we shall be pleased to have notifications of errors and omissions.

Occupational therapists are increasingly working in organisations outside of the public sector. UK government policy over the past decade has promoted health and social care provision by social enterprises. The purpose of this paper is to examine the compatibility of occupational therapy practice and a social enterprise environment, within the UK and questions if this approach may enhance experiences of social inclusion for people who use these services.

Case study methodology was used with eight social enterprises in the UK. Data were collected through: semi-structured interviews, formal organisational documents, and field visits and observations. Interviews were conducted with 26 participants who were occupational therapists, service users and social entrepreneurs/managers. The interviews were recorded, transcribed and analysed using thematic analysis.

Occupational therapists experienced job satisfaction, professional autonomy and were able to practise according to their professional philosophy. Service users valued support with: employment, routine, social relationships, and developing a sense of identity, particularly outside of a medical model definition. To a degree therefore, people using these services claimed socially inclusive benefits. Challenges with funding social enterprises, however, impacted occupational therapy delivery in some cases.

The majority of social enterprise research is drawn from case study methodology; however, this was the most appropriate research design to gain greatest insight into a small but developing phenomenon. Further research into occupational therapy practice within social enterprises is required, particularly on the effectiveness of returning to work and social inclusion.

Social enterprises can provide therapeutic environments to promote recovery and social inclusion which is also compatible with occupational therapy practice.

This is the first known national research into occupational therapy provision in social enterprises within the UK, which evidences a compatibility within occupational therapy practice within a social enterprise environment and the benefits of this.

Organisational change, for some employees, can pose threat, for others challenge. It has been found that, given the same organisational stressors, certain individuals fall victim to stress and ill‐health, whereas others remain healthy. In order to seek a clearer understanding of this phenomenon, the personality/stress/health relationship is explored with reference to individual differences in Type A behaviour, locus of control, hardiness, extraversion, neuroticism, and tension discharge rate. It is suggested that organisational change management should be within the framework of communication, control and counselling. Future research should pursue a multidimensional, interactive course to gain a greater insight into this highly complex relationship.

In a boundary layer ingestion (BLI) propulsion system, the fan operates continuously under distorted inflow conditions, leading to an increment of aerodynamic loss and in turn impacting the potential fuel burn reduction of the aircraft. Usually, in the preliminary design stage of a BLI propulsion system, it is essential to assess the impact of fuselage boundary layer fluids on fan aerodynamic performances under various flight conditions. However, the hub region flow loss is one of the major loss sources in a fan and would greatly influence the fan performances. Moreover, the inflow distortion also results in a complex and highly nonlinear mapping relation between loss and local physical parameters. It will diminish the prediction accuracy of the commonly used low-fidelity computational approaches which often incorporate traditional physics-based loss models, reducing the reliability of these approaches in evaluating fan performances. Meanwhile, the high-fidelity full-annulus unsteady Reynolds-averaged Navier–Stokes (URANS) approach, even though it can give rather accurate loss predictions, is extremely time-consuming. This study aims to develop a fast and accurate hub loss prediction method for a BLI fan under distorted inflow conditions.

This paper develops a data-driven hub loss prediction method for a BLI fan under distorted inflows. To improve the prediction accuracy and applicability, physical understandings of hub flow features are integrated into the modeling process. Then, the key physical parameters related to flow loss are screened by conducting a sensitivity analysis of influencing parameters. Next, a quasi-steady assumption of flow is made to generate a training sample database, reducing the computational time by acquiring one single sample from the highly time-consuming full-annulus URANS approach to a cost-efficient single-blade-passage approach. Finally, a radial basis function neural network is used to establish a surrogate model that correlates the input parameters and the output loss.

The data-driven hub loss model shows higher prediction accuracy than the traditional physics-based loss models. It can accurately capture the circumferentially and radially nonuniform variation trends of the losses and the associated absolute magnitudes in a BLI fan under different blade load, inlet distortion intensity and rotating speed conditions. Compared with the high-fidelity full-annulus URANS results, the averaged relative prediction errors of the data-driven hub loss model are kept less than 10%.

The originality of this paper lies in developing a new method for predicting flow loss in a BLI fan rotor blade hub region. This method offers higher prediction accuracy than the traditional loss models and lower computational time cost than the full-annulus URANS approach, which could realize fast evaluations of fan aerodynamic performances and provide technical support for designing high-performance BLI fans.

This study presents an investigation of the communicative behaviors and strategies employed in the stimulation and management of productive and destructive conflict in culturally heterogeneous workgroups. Using communication accommodation theory (CAT), we argue that the type and course of conflict in culturally heterogeneous workgroups is impacted by the communicative behaviors and strategies employed by group members during interactions. Analysis of data from participant observations, non‐participant observations, semi‐structured interviews, and self‐report questionnaires support CAT‐based predictions and provide fresh insights into the triggers and management strategies associated with conflict in culturally heterogeneous workgroups. In particular, results indicated that the more groups used discourse management strategies, the more they experienced productive conflict. In addition, the use of explanation and checking of own and others' understanding was a major feature of productive conflict, while speech interruptions emerged as a strategy leading to potential destructive conflict. Groups where leaders emerged and assisted in reversing communication breakdowns were better able to manage their discourse, and achieved consensus on task processes. Contributions to the understanding of the triggers and the management of productive conflict in culturally heterogeneous workgroups are discussed.
