Abstract:
Three distinct literatures address social change: social entrepreneurship, community action research, and social marketing. While these activities have a shared goal to create social change, each orientation approaches their activities from a different perspective. The current work explores how macro-social marketing efforts can benefit from alternative orientations to enhance enduring social change. Social entrepreneurship highlights the importance of enduring resources and considering scalability. Community action highlights the importance of obtaining legitimacy and buy-in from multiple entities in the social change system. Social marketing highlights the importance of an end-user perspective and the application of behavioral theories to create systematic change. This work describes a case study in the Kenyan education context to highlight the value of this approach.

Abstract:
We consider Euclidean functional integrals involving actions that are not exclusively real. This situation arises, for example, when there are t-odd terms in the the Minkowski action. Writing the action in terms of only real fields (which is always possible), such terms appear as explicitly imaginary terms in the Euclidean action. The usual quanization procedure that involves finding the critical points of the action and then quantizing the spectrum of fluctuations about these critical points fails. In the case of complex actions, there do not exist, in general, any critical points of the action on the space of real fields, the critical points are in general complex. The proper definition of the function integral then requires the analytic continuation of the functional integration into the space of complex fields so as to pass through the complex critical points according to the method of steepest descent. We show a simple example where this procedure can be carried out explicitly. The procedure of finding the critical points of the real part of the action and quantizing the corresponding fluctuations, treating the (exponential of the) complex part of the action as a bounded integrable function is shown to fail in our explicit example, at least perturbatively.

Abstract:
Purpose This paper aims to expose the inadequacy of social marketing to tackle complex social problems, while proposing an expansion in the discipline’ conceptual repertoire. The goal is to incorporate complexity tools, in particular from the system dynamics field, and the promotion of mindware within a true transdisciplinary paradigm. Design/methodology/approach This paper uses literature review to support the proposed theoretical development. It also presents a short case study. Findings Most problems that plague our modern societies have a distinctive complex nature that is not amenable to traditional social marketing interventions. Social marketing has simplified the problem of bringing about societal change by thinking that upstream social actors can be influenced in the same way as downstream individuals. This paper shows that this is not the case while proposing a framework to close this gap. Research limitations/implications The proposed framework is a theoretical one. It depends on further refinements and actual application to wicked problems. Practical implications Complex social problems – or wicked problems – remain widespread in modern societies. Moreover, they are getting worse over time. The paper presents a proposal to redefine the limits of the social marketing discipline so it can be more useful to tackle such problems. Practical approaches such as measuring the success of mindware in the marketplace of ideas are implied in the proposed framework. Social implications The increase in complexity of social problems has not been accompanied by an evolution in the discipline of social marketing. The lack of proper conceptual tools has prevented the discipline from contributing to tackling these problems effectively. Some interventions may actually worsen the underlying problems, as illustrated in the paper. Originality/value This paper identifies two major gaps associated with the social marketing discipline, in particular the lack of complexity and systems thinking and the forsaking of ideas (mindware) as a legitimate goal of the discipline. This realization corroborates the claim that boundaries among disciplines are often artificial, hindering the proper understanding of complex social problems. In turn, only the use of adequate conceptual lenses makes it possible to devise interventions and programs that tackle actual causes (instead of symptoms) of complex social problems.

Abstract:
The article analyzes the current problems, functional strategies and instigating trends of the agroindustrial complex. The author describes the possible ways of solving problems and considers the prospects for the development of small-scale enterprises based on the existing government support programs for rural areas. Among the most acute problems for the successful development of farms, the author identifies the following groups of problems: 1. Economic problems: rising prices for fuels and lubricants; the volatility of the ruble exchange rate; the constant increase in tariffs for gas, electricity, fertilizers, machinery for agricultural production; the disproportion of prices of products and resources spent on their production; the lack of long-term supportive programs of preferential lending and leasing services; low level of innovation and investment activity; low level of solvency of the population; unsatisfactory state of telephone and Internet communications, roads and transport links; monopolization of sales markets by large agricultural holdings; insufficient development of marketing and logistics issues; weak image advertising of farm products and the lack of integrated marketing communications, which reduce the profitability and profitability of agricultural production. 2. Technological problems: technical and technological lagging behind the developed countries; low technological efficiency of agricultural production of peasant farms; a high degree of deterioration of the equipment and machinery. 3. Ecological problems: industrial and agricultural enterprises impacting on the environment; the inrease in land fertility; the use of pesticides leading to soil and water pollution; the lack of effective control over the quality and safety of food. 4. Social problems of rural areas: the lack of educational institutions with educational services of high quality and developed infrastructure; the lack of jobs for the adult population and youth's low interest in farming as a way of life; domestic problems.

Abstract:
This article arose while working on the rhino poaching problem in South Africa and having to deal with the large number of stakeholders and complexity. The purpose of actor modelling is to develop a deeper understanding of how stakeholders and threats contribute to the complex security problems. This article is the author's reflection on two different attempts at modelling actors in the rhino problem. A framework is developed and a number of issues are raised with respect to actor modelling: First, values and perspectives are driven by actor needs. The knowledge acquired by actors is determined by perspectives. With a diversity of actors, there is a “fragmentation of perspective” that hampers addressing the problem. Thus, dealing with fragmentation of perspective, requires an approach that is inclusive of actors and different ways of knowing. The validity of actor modelling is limited by what can be determined about the values and interests of actors and this varies across actors. Second, actors have multiple identifications with multiple levels of relationality. For high levels of identification combined with low levels of relationality, there is a challenge for a researcher to understand actor behaviour. Third, actors operate in an autonomy-heteronomy space. This is not a continuum, but both autonomy and heteronomy experienced at the same time. When actors are autonomous they live out their values and interests and are most creative. When creativity is applied, there are many ways (what) of satisfying interests and living out values (why), but actors do not behave randomly. Under autonomy, understanding motivation (why) is more important than what because why is more stable and what cannot be predicted. Actors are dynamic, non-deterministic and non-linear. Fourth, the model represents not only structure but also motivation or purpose and resources; thus, addressing certain aspects of subjective and objective fragmentation. Based on the argument advanced in the paper, the sources of actor complexity leading to novel emerging behaviour in social systems are actor needs and the corresponding values and perspectives, high levels of identification with low levels of relationality and autonomy.

Abstract:
We deepen Adam Burgess’ insight that under current conditions nudging cannot solve complex policy problems reliably and without controversy. We do so by integrating his concerns about nudging into Braden Allenby and Daniel Sarewitz's three-leveled model of the basic problems technology can address and generate. We use this model to explain why the UK experiment with nudging has revolved around techno-fixes with limited policy potential, and conclude that nudging is best seen as an emerging form of soft law.
