Impact of Leadership Style and Happiness on Firm Performance

Podsakoff et al. (1990) recognized that there exist six different key classes of transformational leadership behaviours which range from the articulation of a vision, provision for providing an suitable model (e.g., leading by example), encouragement for taking group decisions, having expectations for higher levels of performance, provision for personalised support, and providing rational encouragement (MacKenzie, Podsakoff, and Rich 2001). Transformational leadership aims at altering the standards, values, goals, morals at the fundamental level, and ambitions of different followers with the vision that they will perform their assigned work because it will be consistent with their own values, as opposed to the belief that they will be rewarded for their efforts. Therefore, transformational behaviours are considered to the most active means for impacting followers, whereas the behaviour adopted by transactional leaders is believed to be more reactive in nature (MacKenzie, Podsakoff, and Rich, 2001). The approach followed by the leadership-centred culture develops leaders which do not consider employees as mere cogs in a machine, or as linkage for bureaucratic processes, but considers them human capital which is worthy of cherishing, faith, and admiration. Open-minded leaders endeavour to achieve results from dedicated individuals who keep both private and professional stakes in the organisation.
Are You Ready to Lead?
Published in Anthony Graffeo, Leading Science and Technology-Based Organizations, 2018
Once you have determined the degree of difficulty of the assignment, the next step is to determine who you will need to help you succeed. Many assignments require only your personal leadership and you will be able to assess whether you have sufficient attributes to succeed. If the assignment involves team leadership, your sphere of influence necessarily broadens to include your peers. Team leadership, leading like-minded professionals, requires a step jump in your level of self-awareness. It is one of the major hurdles faced by technical professionals that assume group management positions. Influence increases with the realization that you do not have to be the best technical professional in the group, only a good “player coach” that can contribute technically but focuses most of your time and leadership skills on the success of the group. Only when you temper your professional ego, will you be able to gain the groups’ confidence and trust in your leadership abilities (Figure 3.2).

transformational leadership appears to have an advantage over coercive or directive-only leadership because employees perceive that they are being both considered and included in the change decision, ultimately leading to higher employee support of the change. the difference in the research points towards the ability of transformational leadership to effectively establish higher levels of communication, participation, and trust from their employees than other leadership styles.25
Influence of substrate type on deformation specificity of soft film/hard substrate coated systems under nanomicroindentation

The continuous development of modern nanoindustry, which aims to create structures with qualitatively new properties, has prompted researchers to search for specific materials. Here, the leading place belongs to the coated systems (CSs) of the ‘thin film/bulk substrate’ type. They are of particular interest in the technologies of micro and nanoelectromechanical systems (MEMS and NEMS) [1,2]. The most common planar structures used in semiconductor technology are soft film/hard substrate structures (Al/Si, Cu/Si, Cu/SiO2/Si, etc.) [3–9]. Moreover, in recent years, preference has been given to the CSs Cu/substrate, owing to the higher conductivity and better electro-migration properties of copper compared to aluminum. This factor is very important, considering the tendency toward smaller integrated circuits and reduced energy consumption [1,2,10].
Use of a blast coating process to promote adhesion between aluminium surfaces for the automotive industry

The design of automobile body structures has changed dramatically over the last hundred years from a traditional body-on-frame concept to the monocoque design and finally to the unibody design [1]. With increased demands for safety and luxury, vehicles were becoming too heavy and so aluminium spaceframes are now often used instead of the traditional steel structures to reduce CO2 emissions [2]. The main elements of a self-supporting unibody car structure are load-carrying profiles, stiffening sheets and the required joining elements [1]. Methods of joining present significant challenges when it comes to using aluminium as the main supporting structure [3]. The most common methods of joining aluminium in the automotive industry are: liquid and solid state welding [3], use of mechanical fasteners, adhesive bonding [2,3] and various combinations of these techniques. Each method presents significant challenges. Difficulties associated with welding aluminium are due to the metal’s stable oxide layer and the solubility of hydrogen in aluminium leading to hydrogen adsorption and porosity in the weld [4]. Despite the use of passivation coatings, mechanical fastners are frequently subject to galvanic corrosion due to the contact between the steel rivets and aluminium panels [5]. Some limitations of using adhesively bonded joints include the lack of knowledge surrounding the long-term weatherability of the joints and the effects of environmental attack. They are also inherently weak in peel so the vehicle design needs to be altered to compensate for this through the use of lap shear joints [2].
Cathodic arc deposition of NiCrAlY coating: oxidation behaviour and thermodynamic
Published in Surface Engineering, 2019

As shown in Figure 6, there was the distribution of internal oxides within the NiCrAlY coating. Therefore, thermodynamic measurements had to be performed in the presence of oxygen. The line-scanning profile in Figure 7(a) shows that the oxygen content was about 1.5 wt-% in the coating. Thermodynamic calculations for the Ni-20Cr-xAl-0.5Ti-1.5O (x = 1–11) alloy oxidation at 1000°C are presented in Table 4. The values of ΔG and activity are plotted in Figure 9. When the Al concentration reached to less than 2 wt-%, the Al activity was decreased rapidly. This was because most of Al reacted with oxygen, leading to the formation of aluminium oxide. As can be seen in Figure 9, the Gibbs free energy of the formation of Al2O3 was increased by decreasing the Al concentration. At the concentration of 1.8 wt-% Al, both Al2O3 and TiO2 had the same Gibbs free energy of formation. At concentrations lower than 1.8 wt-% Al, the Gibbs free energy of the formation of TiO2 became more negative, and the driving force for TiO2 was more than that of Al2O3. In such a situation, TiO2 could be formed beneath the Al2O3 scale.
