Are leaders born or made? Trait theory claims that leadership is intrinsic intelligence. While the behavioural theory has debated that leadership requires vision, decisiveness, confidence to take risks, and these can be successfully developed by an individual. As the new industries are emerging, and at the time of COVID-19 pandemic, it is evident that leadership traits are practised and adopted when required. The swift transaction of the manager to become a leader is explained pre-eminently utilizing “be-do-know” model of leadership. For the study, 52 consultants from distinct industries such as IT/ITES, FMCG, agriculture, pharmaceutical, automobile, and manufacturing were administered through a questionnaire and interviews. The study clearly indicates that stimulus such as organizational change, innovation, crises, and correction spin-off the development of first-time leaders.

PurposeGunther Anders in the 20th century and Hartmut Rosa in the 21st have argued that the technics of organization – that is, its physical and social technologies, have from acceleration become so uncontrollable and unpredictable that circumstances actually outstrip awareness to the degree that intentional “organizing” is more a fable than a reality, as stated in the quote from Rosa that forms the title of this article.Design/methodology/approachIn this article, two critical theorists are examined who have fundamentally rejected the “control” thesis that dominates organization theory. It is a thesis that assumes that organizational change ought to be goal-directed, leadership driven and make use of soft and hard technologies to achieve defined objectives.FindingsThe prevailing “idea” of organizing has become illusionary. The technics of accelerationism have overpowered it. Not “organizing” but “ethic-sizing” is what remains as the: “What is to be done.”Originality/valueThe tradition of Gunther Anders and Hartmut Rosa (second and third generation Frankfurter School) and the implications of their work for our assumptions about the relations between technology, control and organization is for a first time evidenced in this article.

This research paper on the critique of the leadership theories and the proposed leadership framework revolves around two key areas. The first part is an examination and critique of the different leadership theories that have emerged over the past 40 years. Second, the paper will be presenting the proposed leadership framework which could suit the role of an education leader. The proposed leadership framework will be presented in a diagrammatic and/or descriptive form with accompanying description. The critique of the leadership theories is specifically on three theories, which are the trait theory, behavioural theory, and contingency and situational theory. The rationale behind the choices of the three theories to be critiqued in this paper was because these theories are the most commonly used and applied in the areas of teaching, learning, and leadership in education.

To Come

Leadership is the ability of an individual to influence people to achieve desired goals. Different studies in this area have propounded various theories ranging from Trait theory of leadership to behavioral approach models to contingency models. Earlier people were of the opinion that individuals are born with leadership traits, either they are born leaders or are not. Then came a phase when people realized that these traits can be acquired too. But all these studies could not come up with any conclusive list of leadership traits. Various successful leaders may have similar traits but we are yet to come across the set of traits that every leader must possess. In nut shell we may say that, “which traits to acquire”, which specific traits make you a leader is still a question? Now a day's increasingly, scholars are talking about transformational leadership as a tool to get better results in the organization. Transformational leaders influence the employee job satisfaction and morale in a positive manner. Responding to this requirement of industry, in this paper the researcher has made an attempt to identify the traits which a transformational leader must possess. The study is based on a descriptive analysis of Durga Saptashati - a Hindu religious text. The study arrived at a conclusive summary of the traits of a transformational leader. Study revealed that the transformational leader has to be perceived as a mn with solutions rather than the man with problems.

Although the presence of annulate lamellae was noted in many cell types, including the rat spermatogenic cells, this structure was never reported in the Sertoli cells of any rodent species. The present report is based on a part of our project on the effect of torsion of the spermatic cord to the contralateral testis. This paper describes for the first time, the fine structural details of the annulate lamellae in the Sertoli cells of damaged testis from guinea pigs.One side of the spermatic cord of each of six Hartly strain adult guinea pigs was surgically twisted (540°) under pentobarbital anesthesia (1). Four months after induction of torsion, animals were sacrificed, testes were excised and processed for the light and electron microscopic investigations. In the damaged testis, the majority of seminiferous tubule contained a layer of Sertoli cells with occasional spermatogonia (Fig. 1). Nuclei of these Sertoli cells were highly pleomorphic and contained small chromatinic clumps adjacent to the inner aspect of the nuclear envelope (Fig. 2).

A new Zeiss TEM with an imaging Omega filter is a fully digitized, side-entry, 120 kV TEM/STEM instrument for materials science. The machine possesses an Omega magnetic imaging energy filter (see Fig. 1) placed between the third and fourth projector lens. Lanio designed the filter and a prototype was built at the Fritz-Haber-Institut in Berlin, Germany. The imaging magnetic filter allows energy-filtered images or diffraction patterns to be recorded without scanning using efficient area detection. The energy dispersion at the exit slit (Fig. 1) results in ∼ 1.5 μm/eV which allows imaging with energy windows of ≤ 10 eV. The smallest probe size of the microscope is 1.6 nm and the Koehler illumination system is used for the first time in a TEM. Serial recording of EELS spectra with a resolution < 1 eV is possible. The digital control allows X,Y,Z coordinates and tilt settings to be stored and later recalled.

Microstructural Studies

Microstructural studies by transmission electron microscopy (TEM) of diamond films grown by chemical vapor deposition (CVD) usually involve tedious specimen preparation. This process has been avoided with a technique that is described in this paper. For the first time, thick as-grown diamond films have been examined directly in a conventional TEM without thinning. With this technique, the important microstructures near the growth surface have been characterized. An as-grown diamond film was fractured on a plane containing the growth direction. It took about 5 min to prepare a sample. For TEM examination, the film was tilted about 30-45° (see Fig. 1). Microstructures of the diamond grains on the top edge of the growth face can be characterized directly by transmitted electron bright-field (BF) and dark-field (DF) images and diffraction patterns.

Transmission and analytical electron microscopic studies of scale microstructures and microscopic marker experiments have been carried out in order to determine the transport mechanism in the oxidation of Ni-Al alloy. According to the classical theory, the oxidation of nickel takes place by transport of Ni cations across the scale forming new oxide at the scale/gas interface. Any markers deposited on the Ni surface are expected to remain at the scale/metal interface after oxidation. This investigation using TEM transverse section techniques and deposited microscopic markers shows a different result,which indicates that a considerable amount of oxygen was transported inward. This is the first time that such fine-scale markers have been coupled with high resolution characterization instruments such as TEM/STEM to provide detailed information about evolution of oxide scale microstructure.

First Time

The electron holes confined to the CuO2-plane are the charge carriers in high-temperature superconductors, and thus, the distribution of charge plays a key role in determining their superconducting properties. While it has been known for a long time that in principle, electron diffraction at low angles is very sensitive to charge transfer, we, for the first time, show that under a proper TEM imaging condition, it is possible to directly image charge in crystals with a large unit cell. We apply this new way of studying charge distribution to the technologically important Bi2Sr2Ca1Cu2O8+δ superconductors.Charged particles interact with the electrostatic potential, and thus, for small scattering angles, the incident particle sees a nuclei that is screened by the electron cloud. Hence, the scattering amplitude mainly is determined by the net charge of the ion. Comparing with the high Z neutral Bi atom, we note that the scattering amplitude of the hole or an electron is larger at small scattering angles. This is in stark contrast to the displacements which contribute negligibly to the electron diffraction pattern at small angles because of the short g-vectors.

Beam Damage

Over the past decade low voltage scanning electron microscopy (LVSEM) of polymers has evolved from an interesting curiosity to a powerful analytical technique. This development has been driven by improved instrumentation and in particular, reliable field emission gun (FEG) SEMs. The usefulness of LVSEM has also grown because of an improved theoretical and experimental understanding of sample-beam interactions and by advances in sample preparation and operating techniques. This paper will review progress in polymer LVSEM and present recent results and developments in the field.In the early 1980s a new generation of SEMs produced beam currents that were sufficient to allow imaging at low voltages from 5keV to 0.5 keV. Thus, for the first time, it became possible to routinely image uncoated polymers at voltages below their negative charging threshold, the "second crossover", E2 (Fig. 1). LVSEM also improved contrast and reduced beam damage in sputter metal coated polymers. Unfortunately, resolution was limited to a few tenths of a micron due to the low brightness and chromatic aberration of thermal electron emission sources.

Both educational and health care organizations are in a constant state of change, whether triggered by national, regional, local, or organization-level policy. The speech-language pathologist/audiologist-administrator who aids in the planning and implementation of these changes, however, may not be familiar with the expansive literature on change in organizations. Further, how organizational change is planned and implemented is likely affected by leaders' and administrators' personal conceptualizations of social power, which may affect how front line clinicians experience organizational change processes. The purpose of this article, therefore, is to introduce the speech-language pathologist/audiologist-administrator to a research-based classification system for theories of change and to review the concept of power in social systems. Two prominent approaches to change in organizations are reviewed and then discussed as they relate to one another as well as to social conceptualizations of power.
