This paper aims to present the basic assumptions for creation of social lasers and attract attention of other researchers (both from physics and socio-political science) to the problem of modeling of Stimulated Amplification of Social Actions (SASA).

The model of SASA and its analysis are based on the mathematical formalism of quantum thermodynamics and field theory (applied outside of physics).

The presented quantum-like model provides the consistent operational model of such complex socio-political phenomenon as SASA.

The model of SASA is heavily based on the use of the notion of social energy. This notion has not yet been formalized.

Evidence of SASA (“functioning of social lasers”) is rapidly accumulating, from color revolutions to such democratically structured protest actions as Brexit and the recent election of Donald Trump as the President of the USA. The corresponding socio-political studies are characterized by diversity of opinions and conclusions. The presented social laser model can be used to clarify these complex socio-political events and even predict their possibility.

SASA is the powerful source of social instability. Understanding its informational structure and origin may help to stabilize the modern society.

Application of the quantum-like model of laser technology in social and political sciences is really a novel and promising approach.

The purpose of this paper is to investigate the perceptions of school governing bodies (SGBs) members’ role in financial management in no-fee schools so as to understand their compliance with policy frameworks when managing school finances. No-fee schools are schools in which the learners cannot be levied fees because of the poor socio-economic background of their parents, and are located in Quintiles 1-3 according to National Norms and Standards for School Funding Policy.

A qualitative research design/approach within the interpretive paradigm was adopted for the study. A sample of 22 participants from six selected no-fee schools was purposefully selected to participate in the study. The participants were principals, SGB chairpersons, SGB treasurers and finance officers. Data were collected through interviews and document analyses and were qualitatively analysed through coding and categorisation.

The findings reveal that the perceptions, experience and understanding of SGB members on their financial management roles differ. They lacked the proper knowledge to manage their funds effectively. This lack of knowledge is mainly because of the members’ literacy level and limited training.

This study offers a novel empirical and theoretical perspective on finance of no-fee schools and SGBs. This research subsequently recommends that rigorous training of chairpersons and treasurers should be done by department officials located in the finance section. Further, training should be conducted in a language that would be understood by the intended recipients.

This paper aims to explore John Mbiti’s concept of African time in line with the studies on the crisis of the post-independence African state. Then, how this concept offers new analytical spaces for understanding the modern nation-states inconveniences in African contexts.

The paper analyses the Mbitian African concept of time in light of the works on post-independence African state and communalism.

By using the Mbitian concept of time politically after explaining African communalism and African concepts of personhood and destiny, the paper reached a conclusion. This conclusion claims that due to the highly existential nature of the African concept of destiny and the past-oriented feature of the African concept of time, Africans cannot be restrained by any supernatural claim or any futuristic promises that are irrelevant to their context and cut from the communal values of ancestral past. Africans do not think supernaturally or bet for the future. However, those futuristic and supernatural claims that cannot restrain the African subjectivity – ironically – characterize the modern nation state with its “progress orientation” and “social-contract” metaphysics. Unfortunately, this radical difference in perceptions between the past-oriented African temporality and the future-oriented modern state temporality rendered the post-independence. African state dysfunctional and unable to operate as a medium for authority. This, consequently, opened the door for informal conflict and strife.

The paper is novel with regard to offering a new theory on the conceptual problems of the nation state in African contexts.

Industry 4.0 emerged as the Fourth Industrial Revolution aiming at achieving higher levels of operational efficiency, productivity and automation. In this context, manual assembly systems are still characterized by high flexibility and low productivity, if compared to fully automated systems. Therefore, the purpose of this paper is to propose the design, engineering and testing of a prototypal adaptive automation assembly system, including greater levels of automation to complement the skills and capabilities of human workers.

A lab experimental field-test is presented comparing the assembly process of a full-scale industrial chiller with traditional and adaptive assembly system.

The analysis shows relevant benefits coming from the adoption of the adaptive automation assembly system. In particular, the main findings highlight improvements in the assembly cycle time and productivity, as well as reduction of the operator’s body movements.

The prototype is applied in an Italian mid-size industrial company, confirming its impact in terms of upgrades of the assembly system flexibility and productivity. Thus, the research study proposed in this paper provides valuable knowledge to support companies and industrial practitioners in the shift from traditional to advanced assembly systems matching current industrial and market features.

This paper expands the lacking research on adaptive automation assembly systems design proposing an innovative prototype able to real-time reconfigure its structure according to the product to work, e.g. work cycle, and the operator features.

A variety of thick film planar inductors, designed for applications in the HF range, were printed from conductive PdAg and NiFe₂O₄ ferrite paste on alumina substrate. Pure ferrite powder with a nanometric particle size was used in the NiFe₂O₄ paste preparation. The ferrite thick film layer characterisation was performed on small spirals, after which the following inductor planar geometries were tested together with ferrite layers: meanders, spirals, bispirals and solenoid in plane. Their impedance was analysed with an impedance analyser in the MHz‐GHz range. The results obtained were compared with the properties of the smallest cubic inductors and with the literature data for planar inductors (theoretical and practical). A comparison was made of the L geometries printed. It was observed that better utilisation of the thick ferrite layers was achieved on L geometries with equally distributed windings over the thick ferrite layers.

The purpose of this paper is to analyse the extent to which transaction cost theory on hybrid governance structures can explain hybrid personalities observed in the South African sugar industry.

Three governance structures used simultaneously by the same company to purchase sugar cane from small-scale growers are described in detail. One of these structures is close to a market arrangement, the other two are hybrids. The discriminating alignment hypothesis and more recent work on hybrid models are used to explain the factors driving the choice for a hybrid arrangement and determining their specific form. Factors not covered by theory are identified.

At least two areas would need to be included to explain the specific form taken by the studied governance structures: production characteristics and financial constraints of the transacting parties. Furthermore, the importance of national and local regulations in affecting organizational form by determining what is and is not possible is demonstrated.

This case study highlights limitations of current theory in fully explaining the “personality” of governance structures. Future work should not shun the finer details of governance structures and their interaction with the institutional environment.

Inclusive business models are promoted as tools for poverty alleviation and economic development. Public involvement plays an important role, however, more research is required to understand its reach and leverage its full potential.

This paper is the first to rigorously apply transaction cost theory to inclusive business models in agricultural sourcing, an area which is rapidly gaining prominence on the development agenda. It shows that a complete understanding requires going beyond current theory.

The thermal diffusivity of thick film NTC layers based on a metal oxide powder mixture was measured at room temperature by the photoacoustic (PA) technique. The powder mixture was composed of MnO (60 percent), CoO (32 percent) and Fe₂O₃ (8 percent), which were ball milled to nanometer particle size. NTC layers of different thicknesses were made by sequentional screen‐printing followed by drying and co‐firing at 850, 900 and 1,000°C in a hybrid conveyor furnace. The experimental PA phase and amplitude diagrams were numerically analyzed and the thermal diffusivity and electron transport parameters were calculated. An increase of thermal diffusivity with sintering temperature was observed. The fractal structure model was in agreement with the experimental data for modulation frequencies in which the sample behaved as thermally thick.

The purpose of this paper is to explain how leaders balance exploitation (incremental innovation) and exploration (discontinuous innovation).

A qualitative study with 11 senior leaders in Australian Defence Force.

The study identifies a number of factors that leaders take into account when deciding whether to focus on exploitation or on exploration.

The study concludes that transactional leadership is appropriate in the context of exploitation, while transformational leadership is appropriate in the context of exploration.

The purpose of this article is to investigate the effectiveness of accountability mechanisms employed in financial management practices of school principals in the Eastern Cape Provincial Department of Education. The strengths and weaknesses of the systems and mechanisms of the processes to hold school principals accountable are explored in detail in this study. The argument that this article seeks to advance is that accountability of the school principal to the school governing body (SGB) does not yield the best results in terms of efficiency. It creates a loose arrangement in terms of which the school principal takes part in financial mismanagement in schools.

Data collection was made through semi-structured interviews whose purpose was to draw experiences from SGBs, particularly the finance committees who are in fact the sub-committees of the SGBs; as well as literature review. The finance committee is made up of the chairperson of the SGB, the secretary of the SGB, the treasurer of the SGB, and the financial officer who is a clerk responsible for the keeping and the management of financial records of the school. The process started with semi-structured interviews, then transcribing, coding, developing themes, making meaning of the themes and subsequently developing a principle.

Mechanisms employed by schools and the Department of Education to hold principals accountable for their financial management practices fail to make them fully accountable and effectively face the consequences of acts on their part that are illegal and unlawful. The mechanisms need a great deal of overhauling. The argument that this article seeks to advance is that this account of the school principal to the SGB does not yield the best results in terms of efficiency. It creates a loose arrangement in terms of which the school principal easily gets away with a crime when financial mismanagement occurs in the school.

Participants could possibly not be comfortable and willing, to tell the truth as it is. Participants might have the fear that telling the truth could land them in trouble with the law. Whilst participants were assured by the researchers of their anonymity and the confidentiality of the information given by them, there was no guarantee that the fear of being exposed would subdue completely. There was also a possibility that some participants would not be willing to say the truth as it is for fear of being victimised by other participants for exposing the status quo in their schools.

The findings and recommendations from this study may be used by the Department of Basic Education as a source of information for policymakers and stakeholders to understand the effectiveness of their mechanisms to ensure the accountability of school principals on issues of financial management. On the basis of this study, policymakers will then be able to revisit their policies for the purpose of strengthening them. The principal is therefore responsible for the day-to-day administration and management of school funds because of this mandatory delegation. However, when things go wrong, it is the SGB that is held liable.

School principals hold dual accountability in terms of which they are accountable to the employer only in so far as their professional responsibilities are concerned on financial management in the first instance. They are by no means accounting officers in schools. In the second instance, they are fully accountable to the SGB for issues relating to financial management. Section 16A of SASA lists the functions and responsibilities for which the principal as an employee of the Department of Basic Education, and in his official capacity as contemplated in Sections 23(1) and 24(1) (j) of the same Act, is accountable to the head of department (HOD).

The study provides a theoretical and empirical contribution to the existing literature on the effectiveness of the mechanisms employed to ensure the accountability of school principals in their financial management practices in schools. It offers practical recommendations putting in place mechanisms that effectively hold school principals wholly accountable for their financial management practices in schools. Most of the time, it is easy for the principal to get away with a crime even in instances where he or she is called upon to account for alleged financial mismanagement.
