An investigation into the relationship between the leadership competencies, emotional intelligence, and leadership styles of Russian managers working for MNCs

This thesis was submitted for the degree of Doctor of Business Administration and awarded by Brunel University.The need for greater understanding of international leadership models has escalated in tandem with the globalization of trade and commerce. This dissertation presents the comparative-cultural study undertaken to address these two critical issues; employing the Russian Federation as the cultural context for the investigation. Cross-cultural research highlights a deficit of up-to-date comparative data on Russian organizational leadership, whilst practitioners articulate the demand for Russia-appropriate leadership development expertise. Increasingly, scholars advocate the application of integrated theories for assessing organizational leadership; contributing to several scholars updating trait theory into competency terms (including emotional competencies). Recent studies in the UK have established linkages amongst the competencies required for effective leadership, executives’ emotional competencies, and the demonstrated leadership styles of managers. This research extends these UK findings, investigating the possible relationship between the leadership competencies, Emotional Intelligence (EI), and leadership styles of Russian managers working within domestic and foreign MNCs. The researcher employed the Leadership Dimensions Questionnaire (LDQ) as the standardized measurement instrument for conducting this “etic” (comparative) study. The LDQ assesses managers based on 15 dimensions, representing cognitive (IQ), Emotional Intelligence (EQ), and managerial competencies (MQ); generating a leadership style “profile” based on the respondent’s scores. A combination of online and paper-based self-report versions of the LDQ (recently validated and utilized in several key UK studies) facilitated the data collection from the participating Russian managers (n = 152), over a 12- month period. Major findings of this research include: the identification of a clear leadership style preference by the Russian manager-sample (“participative”); statistically significant differences between the Russian and UK samples – on 14 of the 15 dimensions; distinctive differences in the competencies required for senior versus junior managers; “communication” was predictive of Russian leader performance, whilst follower commitment was predicted by leaders’ levels of “sensitivity” and “communication”. Contributions of this research to theory include: the identification of an up-to-date leadership profile of Russian managers, in competency terms, which can be compared with other cultures; a comparative cultural assessment of Russian managers’ based on EI; a comparison of Russian managers at different levels of large companies, with special attention to their similarities and differences. Implications of this research for practitioners include: the ability for organizations operating in Russia to identify/develop leaders based on their personal leadership profiles (executive training and development), as assessed by the LDQ; the potential for identifying and fostering competencies required of managers at higher levels within the organization (promotion; as roles and responsibilities differ at various levels within an organization); the opportunity for matching appropriate leadership styles to conform with organizational strategies and the surrounding business environment (strategic leadership style/context fit)

Novel detectors and algorithms for electron nano-crystallography

In the past decade, advances in structure determination with electron microscopy of organic, beam sensitive, materials have been significant. The newly developed techniques, triggered by new microscope systems and new cameras, made it possible to acquire 3D structural information from these samples to a resolution which was impossible to achieve before. Knowledge is required to improve structure solution and every aspect of the process involved, from treatment of radiation sensitive materials, sample preparation, TEM imaging and diffraction systems all the way to how data must be interpreted. In this thesis I explained multiple new techniques and methods developed by us, using both new microscopes as well as a new type of detector: Timepix. I describe how these tools can help to overcome (what were) the most important problems and bottlenecks in detection of very low dose electron diffraction.UBL - phd migration 201

Acute and Chronic Toxicity of Cobalt to Freshwater Organisms: Using a Species Sensitivity Distribution Approach to Establish International Water Quality Standards

Water quality standards for cobalt (Co) have not been developed for the European Union or United States. The objective of the present study was to produce freshwater Co toxicity data that could be used by both the European Union and the United States to develop appropriate regulatory standards (i.e., environmental quality standards or predicted-no-effect concentrations in Europe and ambient water quality criteria or state water quality standards in the United States). Eleven species, including algae, an aquatic plant, and several invertebrate and fish species, were used in the performance of acute and chronic Co toxicity tests. Acute median lethal or median effective concentration (LC50 or EC50) values ranged from 90.1 mu g Co/L for duckweed (Lemna minor) to 157 000 mu g Co/L for midges (Chironomus tentans). Chronic 10% effect concentration (EC10) values ranged from 4.9 mu g Co/L for duckweed to 2170 mu g Co/L for rainbow trout (Oncorhynchus mykiss). Chronic 20% effect concentration (EC20) values ranged from 11.1 mu g Co/L for water flea (Ceriodaphnia dubia) to 2495 mu g Co/L for O. mykiss. Results indicated that invertebrate and algae/plant species are more sensitive to chronic Co exposures than fish. Acute-to-chronic ratios (derived as acute LC50s divided by chronic EC20s) were lowest for juvenile O. mykiss (0.6) and highest for the snail Lymnaea stagnalis (2670). Following the European-based approach and using EC10 values, species sensitivity distributions (SSDs) were developed and a median hazardous concentration for 5% of the organisms of 1.80 mu g Co/L was derived. Chronic EC20 values were used, also in an SSD approach, to derive a US Environmental Protection Agency-style final chronic value of 7.13 mu g Co/L

Travel-Associated Zika Virus Disease Acquired in the Americas Through February 2016

BACKGROUND: Zika virus has spread rapidly in the Americas and has been imported into many nonendemic countries by travelers. OBJECTIVE: To describe clinical manifestations and epidemiology of Zika virus disease in travelers exposed in the Americas. DESIGN: Descriptive, using GeoSentinel records. SETTING: 63 travel and tropical medicine clinics in 30 countries. PATIENTS: Ill returned travelers with a confirmed, probable, or clinically suspected diagnosis of Zika virus disease seen between January 2013 and 29 February 2016. MEASUREMENTS: Frequencies of demographic, trip, and clinical characteristics and complications. RESULTS: Starting in May 2015, 93 cases of Zika virus disease were reported. Common symptoms included exanthema (88%), fever (76%), and arthralgia (72%). Fifty-nine percent of patients were exposed in South America; 71% were diagnosed in Europe. Case status was established most commonly by polymerase chain reaction (PCR) testing of blood and less often by PCR testing of other body fluids or serology and plaque-reduction neutralization testing. Two patients developed Guillain–Barre syndrome, and 3 of 4 pregnancies had adverse outcomes (microcephaly, major fetal neurologic abnormalities, and intrauterine fetal death). LIMITATION: Surveillance data collected by specialized clinics may not be representative of all ill returned travelers, and denominator data are unavailable. CONCLUSION: These surveillance data help characterize the clinical manifestations and adverse outcomes of Zika virus disease among travelers infected in the Americas and show a need for global standardization of diagnostic testing. The serious fetal complications observed in this study highlight the importance of travel advisories and prevention measures for pregnant women and their partners. Travelers are sentinels for global Zika virus circulation and may facilitate further transmission

Distinct mobility patterns of BRCA2 molecules at DNA damage sites

BRCA2 is an essential tumor suppressor protein involved in promoting faithful repair of DNA lesions. The activity of BRCA2 needs to be tuned precisely to be active when and where it is needed. Here, we quantified the spatio-temporal dynamics of BRCA2 in living cells using aberration-corrected multifocal microscopy (acMFM). Using multicolor imaging to identify DNA damage sites, we were able to quantify its dynamic motion patterns in the nucleus and at DNA damage sites. While a large fraction of BRCA2 molecules localized near DNA damage sites appear immobile, an additional fraction of molecules exhibits subdiffusive motion, providing a potential mechanism to retain an increased number of molecules at DNA lesions. Super-resolution microscopy revealed inhomogeneous localization of BRCA2 relative to other DNA repair factors at sites of DNA damage. This suggests the presence of multiple nanoscale compartments in the chromatin surrounding the DNA lesion, which could play an important role in the contribution of BRCA2 to the regulation of the repair process
