This study aims to reduce the interfacial tension by increasing the better adhesion between different immiscible polymers phases and also to evaluate the mechanical, thermal and thermo-mechanical behavior of the immiscible polymer blends.

The polymer blend composite (PBC) was prepared using a twin-screw extruder followed by injection molding. Two different kinds of PBC with compatibilizer (Ethylene-n-Butylacrylate-Glycidyl methacrylate) of varying compositions like polybutylene terephthalate + poly trimethylene terephthalate and polybutylene terephthalate (30% glass filled) + poly trimethylene terephthalate were prepared and material behavior at various test conditions were studied. The effect of glass fiber reinforcement on polymer blend and the interlocking effect by the compatibilizer between the polymer phases were also assessed.

Mechanical behavior of PBC was estimated by tensile, flexural and angular impact tests. Likewise, the thermal deflection was studied with the help of heat deflection temperature test. Thermo-mechanical behavior likes storage modulus, loss modulus and loss tangent were studied using the dynamic mechanical analysis test. Morphological analysis was characterized using field emission scanning electron microscopy.

This in turn makes the process easy to obtain the PBC having inherent mechanical, thermal and thermo-mechanically stable. And, it also enhances the mechanical properties like tensile, flexural and impact strength. Simultaneously, posse’s excellent heat deflection and thermo-mechanical behavior over a temperature range of 35–140ºC at a constant frequency of 5 Hz.

This case study aims to provide following four learning outcomes: enhanced understanding of organizational leadership style/approach in terms of rigidness or flexibility to bring modifications in organizational vision to tap current opportunities, enhanced understanding of the use of emotions and rationality in organizational decision-making to strike a balance between organizational needs and community needs in the context of organizational priority framework, enhanced understanding of issue of integration to meet community needs smartly particularly in social development organizations and enhanced understanding of leadership strategies for successful business diversification.

This case study highlights and discusses three issues: first, it explores issues related to change in organizational vision and aims keeping in mind the needs of community rather than sticking to organizational needs (flexibility versus rigidity). Second, it explores the role of emotions and rationality in organizational decision-making by its leadership. Third, it discusses the role of leadership in successfully transforming one-dimensional organization into multidimensional organization by adding new avenues for future growth by mobilizing existing organizational strengths and competencies. Finally, this case discusses theories of leadership and change management in the context of social development organizations to align their activities with community’s emerging needs.

Master Level - Master of Business Administration and Master of Management. This case provides sufficient material to be discussed at master level courses such as change leadership and change management in social development organizations.

Despite the increase in studies focused on analyzing the potential of big data analytics capability (BDAC) as a driver of product and process innovation, it is still necessary to understand how the use of insights generated by BDAC in innovation may be maximized through articulation with individuals' intellect and other processes involving the assimilation and transformation of knowledge. This study thus aims to analyze the impact of BDAC's deployment on innovation capability (IC – process and product innovation capabilities), taking absorptive capacity (AC) as mediating variable in this relationship.

Structural equations were used to test the research model with survey data from 112 firms located in an emerging country that is one of the digital transformation leaders in the region.

The results show that 37% of process IC variance is explained by the indirect relationship via the variable mediator (AC), while in the case of product IC this percentage is 34%.

These results allow us to ascertain the extent to which individuals continue to be relevant to generating product and process innovation in the digital age at a time when the literature anticipates a total loss of prominence due to the arrival of new digital technologies. However, in the case of the relationship between BDAC and ICs, the existence of a partial mediation of AC indicates that individuals continue to play a role that, albeit not being the most prominent, remains relevant in ensuring that a company maximizes the assimilation and transformation of the insights generated by BDAC in new products and processes.

The aim of this chapter is to argue that charisma is a collective representation, and that charismatic authority is a social status that derives more from the “recognition” of the followers than from the “magnetism” of the leaders. I contend further that a close reading of Max Weber shows that he, too, saw charisma in this light.

I develop my argument by a close reading of many of the most relevant texts on the subject. This includes not only the renowned texts on this subject by Max Weber, but also many books and articles that interpret or criticize Weber’s views.

I pay exceptionally close attention to key arguments and texts, several of which have been overlooked in the past.

Writers for whom charisma is personal magnetism tend to assume that charismatic rule is natural and that the full realization of democratic norms is unlikely. Authority, in this view, emanates from rulers unbound by popular constraint. I argue that, in fact, authority draws both its mandate and its energy from the public, and that rulers depend on the loyalty of their subjects, which is never assured. So charismatic claimants are dependent on popular choice, not vice versa.

I advocate a “culturalist” interpretation of Weber, which runs counter to the dominant “personalist” account. Conventional interpreters, under the sway of theology or mass psychology, misread Weber as a romantic, for whom charisma is primal and undemocratic rule is destiny. This essay offers a counter-reading.

Current issues of Publishers' Weekly are reporting serious shortages of paper, binders board, cloth, and other essential book manufacturing materials. Let us assure you these shortages are very real and quite severe.

REPERCUSSIONS of the Margate Conference will be felt for some time to come. There is still the suggestion that one or the other side won in the debate on central control, for example, but we would suggest that it was an occasion when a case was stated and combatted and that the result was the only wise one; that is to say, both parties agreed that the Council should consider the matter. It would be in the highest degree dangerous if at any open meeting of over 1,000 members of the Library Association any policy, then for the first time outlined, should be adopted as a settled rule of life. Such questions as central control have to be considered in all their bearings, and admirable as was the case Colonel Mitchell made for it, and forceful as was Mr. Berwick Sayers's rejoinder, they would not be regarded as final statements, even by themselves. There were some murmurings at the swift close of the debate, and there were more than murmurings that so important a matter should arise without due notice. These are not quite reasonable, and no one could have handled the meeting more quietly and impartially than the President (Mr. Savage) did. That no notice was given of the debate is hardly true although the words of the motion proposed by Colonel Mitchell were not known until the debate began; but the intention of the debate was to elicit opinions which might help the council in framing a policy; there was no intention to reach a decision or to publish the results of the meeting. A considered report, twelve months hence, on the deliberations of the L.A. Council on the matter should be far better than any account of the vapourings at Margate.

In 1899 the medical practitioners of Dublin were confronted with an outbreak of a peculiar and obscure illness, characterised by symptoms which were very unusual. For want of a better explanation, the disorder, which seemed to be epidemic, was explained by the simple expedient of finding a name for it. It was labelled as “beri‐beri,” a tropical disease with very much the same clinical and pathological features as those observed at Dublin. Papers were read before certain societies, and then as the cases gradually diminished in number, the subject lost interest and was dropped.

Managing projects is an important part of operations management, but many projects fail. This study focuses on attribution processes of such disruption from the underrepresented perspective of the project manager. The authors consider two types of causes: the more frequently researched environmental uncertainty (i.e. uncontrollable events) and the scarcely researched uncertainty imposed by non-collaborative project sponsors (i.e. other-controllable events).

The authors test conceptual arguments grounded in attribution theory and the notion of psychological contracts in a scenario-based experiment among 325 practicing project managers.

The findings indicate that non-collaborative project sponsors negatively affect project managers' motivation, whereas uncontrollable disruptions leave hope to achieve positive future outcomes. This latter effect is further strengthened when project managers have an internal attribution style. They tend to blame the disruption on themselves and generally feel in control of achieving success even if they are not.

These socio-psychological insights nuance the economic idea that uncertainty reduces motivation per se in the context of project disruption appraisal. The authors contribute to the behavioral project management literature and general attribution theory and help guide the allocation of resources during the recovery of failed projects.

THE centenary celebration is that of the apparently prosaic public library acts ; it is not the centenary of libraries which are as old as civilization. That is a circumstance which some may have overlooked in their pride and enthusiasm for the public library. But no real librarian of any type will fail to rejoice in the progress to which the celebration is witness. For that has been immense. We are to have a centenary history of the Public Library Movement—that is not its title—from the Library Association. We do not know if it will be available in London this month; we fear it will not. We do know its author, Mr. W. A. Munford, has spent many months in research for it and that he is a writer with a lucid and individual Style. We contemplate his task with a certain nervousness. Could anyone less than a Carlyle impart into the dry bones of municipal library history that Strew these hundred years, the bones by the wayside that mark out the way, the breath of the spirit that will make them live ? For even Edward Edwards, whose name should be much in the minds and perhaps on the lips of library lovers this month, could scarcely have foreseen the contemporary position ; nor perhaps could Carlyle who asked before our genesis why there should not be in every county town a county library as well as a county gaol. How remote the days when such a question was cogent seem to be now! It behoves us, indeed it honours us, to recall the work of Edwards, of Ewart, Brotherton, Thomas Greenwood, Nicholson, Peter Cowell, Crestadoro, Francis Barrett, Thomas Lyster, J. Y. M. MacAlister, James Duff Brown and, in a later day without mentioning the living, John Ballinger, Ernest A. Baker, L. Stanley Jast, and Potter Briscoe—the list is long. All served the movement we celebrate and all faced a community which had to be convinced. It still has, of course, but our people do now allow libraries a place, more or less respected, in the life of the people. Librarians no longer face the corpse‐cold incredulity of the so‐called educated classes, the indifference of the masses and the actively vicious hostility of local legislators. Except the illuminated few that existed. These were the men who had the faith that an informed people was a happier, more efficient one and that books in widest commonalty spread were the best means of producing such a people. These, with a succession of believing, enduring librarians, persisted in their Struggle with cynic and opponent and brought about the system and the technique we use, modified of course and extended to meet a changing world, but essentially the same. Three names we may especially honour this September, Edward Edwards, who was the sower of the seed; MacAlister, who gained us our Royal Charter ; and John Ballinger, who was the person who most influenced the introduction of the liberating Libraries Act of 1919.

Community profiling several recent research studies (eg see NLW, June) have emphasised the need for more effective marketing of library and information services. A new CRUS publication is intended to help librarians set about the task of gathering the necessary information to do this properly. Community profiling in the library context aims to define a community in a way which is relevant to the planning and evaluation of library services, but different types of community require different approaches. Christina Beal has now written a comprehensive report covering the different methods possible. Community profiling for librarians (CRUS Occasional Paper 12) costs £17.50 from Consultancy and Research Unit, Department of Information Studies, University of Sheffield, Sheffield S10 2TN (Tel: 0742‐738608).
