The study of the electro-osmotic forces (EOF) in the flow of the boundary layer has been a topic of interest in biomedical engineering and other engineering fields. The purpose of this paper is to develop an innovative mathematical model for electro-osmotic boundary layer flow. This type of fluid flow requires sophisticated mathematical models and numerical simulations.

The effect of EOF on the boundary layer Williamson fluid model containing a gyrotactic microorganism through a non-Darcian flow (Forchheimer model) is investigated. The problem is formulated mathematically by a system of non-linear partial differential equations (PDEs). By using suitable transformations, the PDEs system is transformed into a system of non-linear ordinary differential equations subjected to the appropriate boundary conditions. Those equations are solved numerically using the finite difference method.

The boundary layer velocity is lower in the case of non-Newtonian fluid when it is compared with that for a Newtonian fluid. The electro-osmotic parameter makes an increase in the velocity of the boundary layer. The boundary layer velocity is lower in the case of non-Darcian fluid when it is compared with Darcian fluid and as the Forchheimer parameter increases the behavior of the velocity becomes more closely. Entropy generation decays speedily far away from the wall and an opposite effect occurs on the Bejan number behavior.

The present outcomes are enriched to give valuable information for the research scientists in the field of biomedical engineering and other engineering fields. Also, the proposed outcomes are hopefully beneficial for the experimental investigation of the electroosmotic forces on flows with non-Newtonian models and containing a gyrotactic microorganism.

This issue is a selected bibliography covering the subject of leadership.

The purposes of this study are to (i) systematically review the state of the existing research of talent management (TM) in emerging markets and its connections with firm performance; (ii) recap the results in an integrative and multidisciplinary framework and (iii) recognize potential research contradictions and gaps that offer avenues for future study.

In this study, the authors apply a systematic literature review (SLR) methodology to review 31 peer-reviewed articles published in highly ranked journals (ABS journals list – ranking 3, 4 and 4*) over more than two decades.

This review shows that the state of the current research of TM in emerging countries and its connections with firm performance is characterized by complexity and fragmentation within the different countries investigated. This review summarizes and highlights five central categories of TM in emerging markets. In order to ensure that the field of research investigated continues to be relevant to diverse constituents, the authors incorporate the various prominent research perspectives into an integrative framework structured at macro (economies/countries), meso (industries) and micro (individuals/organizations) levels.

This research provides guidance for chief executive officers, chief financial officers and human resource directors in emerging countries to develop TM within their organization in order to capture its relevant aspects, from a strategic (purposeful and competency modeling), organizational (talent planning and career track planning) and financial point of view (remuneration policy and firm performance).

The authors offer a first holistic overview of the features of TM in emerging markets and also introduce firm performance. The authors present an integrative multidisciplinary framework that can serve as a starting point of a summary of areas covered by the literature. Finally, the authors identify several knowledge gaps, emerging topics and limitation of current research, through which ideas for future investigations are offered.

The purpose of this paper is to elaborate on the commonality between the Theory of Didactical Situations (TDS) and lesson study to propose a model of lesson study using both the predominant graphical representation of lesson study by Lewis and the model of the didactical situation at the heart of TDS by Brousseau.

Starting by describing and adapting the predominant graphical representation of lesson study by Lewis and the model of the didactical situation at the heart of TDS by Brousseau, the paper integrates the two representations to highlight the commonalities between the students’ learning situation and the teachers’. Based on this integrated graphical representation, the key phases of lesson study are then conceptualised by the mean of the dialectic between didactical and adidactical situation.

The reflection about the use of the TDS graphical representation embedded in the lesson study diagram helps the reflection on the use of TDS itself to analyse lesson study. This theoretical analysis describes the process of teacher learning in lesson study and the link between their learning and the student’s. It also shows that lesson study is a good candidate for the fundamental situation of the knowledge for teaching.

The graphical conceptualisation of lesson study as a learning situation for teachers offers new insight about how teachers learn in lesson study.

AS J. L. Hobbs shows so clearly in his recent book, the interest in local history is growing enormously at present. The universities, training colleges and schools, as well as the institutions of further education, are all making more use of local studies—geographical, economic, social and historical—in their regular courses, in their advanced work, and in their publications.

WE write on the eve of an Annual Meeting of the Library Association. We expect many interesting things from it, for although it is not the first meeting under the new constitution, it is the first in which all the sections will be actively engaged. From a membership of eight hundred in 1927 we are, in 1930, within measurable distance of a membership of three thousand; and, although we have not reached that figure by a few hundreds—and those few will be the most difficult to obtain quickly—this is a really memorable achievement. There are certain necessary results of the Association's expansion. In the former days it was possible for every member, if he desired, to attend all the meetings; today parallel meetings are necessary in order to represent all interests, and members must make a selection amongst the good things offered. Large meetings are not entirely desirable; discussion of any effective sort is impossible in them; and the speakers are usually those who always speak, and who possess more nerve than the rest of us. This does not mean that they are not worth a hearing. Nevertheless, seeing that at least 1,000 will be at Cambridge, small sectional meetings in which no one who has anything to say need be afraid of saying it, are an ideal to which we are forced by the growth of our numbers.

This paper investigates the feasibility of using the emission intensity of low‐pressure argon and nitrogen gas discharges as the sensing mechanism for a microwave electric field optical sensor probe in microwave resonant cavities. The emission is coupled to a photodiode for detection through an optical fibre due to the difficulty in using conventional optoelectronic devices in close proximity to microwave cavities. The discharge emission intensity is monitored at a range of different input powers to the cavity. The proposed designs for the electric field sensing probe are also included.

The more severe cases of mental subnormality have shown a fairly random social distribution, but mild subnormality is typically a lower‐class phenomenon. Various deterministic formulations have been offered in explanation of this, ranging from hereditarian notions of “bad stock” among the lower classes to environmentalist em‐phasis upon the debilitating effect of poor social circumstances. This article argues that such attempts to account for the social distribution of subnormality in terms of aetiology are premature, because the processes whereby people come to be labelled as subnormal are largely unexamined.

The purpose of this paper is to identify and ranks factors that influence bank selection by undergrads in South East Nigeria.

Totally, 300 undergrads were sampled from two universities. Five-point Likert-type question containing 49 bank selection items was designed to collect primary data. Cronbach's α was used to test the reliability of the instrument while factor analysis with principal component extraction was used to identify the underlying factors.

Six principal factors were identified and ranked in order of importance. These factors are: bank's financial stability, available and functional ATMs, professional bank staff, family and friends influence, proximity of bank branch to university campus, and internal and external aesthetics of bank.

This study provides insight on the factors that influence the selection of a bank in the emerging and growing undergrads segment of bank market in Nigeria, which has obvious management and theory implications.

Reports bank selection criteria from apparently under-researched and under-reported undergrad segment in a typical sub-Saharan African context.

This paper aims to extend the literature on how to harness the expertise of team members. This paper suggests that the leader’s expertise recognition plays an important role in enhancing team effectiveness. In addition, leader’s personal dispositions shape how the leader’s recognition could benefit team expertise utilization.

This paper utilizes a two-wave, multi-source (team leaders and team members rated) survey design from 78 information technology teams to test the proposed moderated mediation model.

The data analysis revealed that a leader’s expertise recognition is positively related to team expertise utilization. Moreover, the leaders’ traits (i.e. social dominance and reflectiveness) act as important boundary conditions of this relationship. Specifically, only when the leader is less socially dominant or more reflective can they fully utilize the expertise recognition and enhance team creativity through team expertise utilization.

This study investigated an important issue that expertise utilization research has hitherto overlooked: the effects of leader’s expertise recognition on team expertise utilization and team creativity.
