Knowing what Social Enterprises know
Social Enterprises (SEs) are normally micro and small businesses that trade to tackle social problems, and to improve communities, people’s life chances, and the environment. Thus, their importance to society and economies is increasing. However, there is still a need for more understanding of how these organisations operate, perform, innovate and scale-up. Obtaining this understanding is the main driver of this paper, which explores the SE activities to manage their knowledge. Interviews from 21 owners and senior members of SEs in UK confirmed that SEs possessed valuable tacit and explicit knowledge about their organisation, practices, experiences and work with communities and costumers. This knowledge is managed informally and, when acquired, is not always converted into usable knowledge, applied to create value, and protected from inappropriate or illegal use. Thus, SEs need to know what they know and manage effectively that knowledge. This can help them to acquire, convert, apply and protect all their knowledge that would result in added value to their organisation and stakeholders, legitimised their practice, adjusted and defined their operational and strategic direction, and informed the measurement of their social impact. This paper contributes to SE and Knowledge Management researchers, SE practitioners and organisations supporting SEs
Multi-wavelength, all-solid-state, continuous wave mode locked picosecond Raman laser
We demonstrate the operation of a cascaded continuous wave (CW) mode-locked Raman oscillator. The output pulses were compressed from 28 ps at 532 nm down to 6.5 ps at 559 nm (first Stokes) and 5.5 ps at 589 nm (second Stokes). The maximum output was 2.5 W at 559 nm and 1.4 W at 589 nm with slope efficiencies up to 52%. This technique allows simple and efficient generation of short-pulse radiation to the cascaded Stokes wavelengths, extending the mode-locked operation of Raman lasers to a wider range of visible wavelengths between 500 - 650 nm based on standard inexpensive picosecond Nd:YAG oscillators
Hard breakup of the deuteron into two Delta-isobars
We study high energy photodisintegration of the deuteron into two
-isobars at large center of mass angles within the QCD hard
rescattering model (HRM). According to the HRM, the process develops in three
main steps: the photon knocks the quark from one of the nucleons in the
deuteron; the struck quark rescatters off a quark from the other nucleon
sharing the high energy of the photon; then the energetic quarks recombine into
two outgoing baryons which have large transverse momenta. Within the HRM, the
cross section is expressed through the amplitude of scattering which we evaluated based on the quark-interchange
model of hard hadronic scattering. Calculations show that the angular
distribution and the strength of the photodisintegration is mainly determined
by the properties of the
scattering. We predict that the cross section of
the deuteron breakup to is 4-5 times larger than that
of the breakup to the channel. Also, the angular
distributions for these two channels are markedly different. These can be
compared with the predictions based on the assumption that two hard
-isobars are the result of the disintegration of the preexisting
components of the deuteron wave function. In this case, one
expects the angular distributions and cross sections of the breakup in both and channels to be similar.Comment: 17 pages, 3 figure
The scattering map in two coupled piecewise-smooth systems, with numerical application to rocking blocks
We consider a non-autonomous dynamical system formed by coupling two
piecewise-smooth systems in \RR^2 through a non-autonomous periodic
perturbation. We study the dynamics around one of the heteroclinic orbits of
one of the piecewise-smooth systems. In the unperturbed case, the system
possesses two normally hyperbolic invariant manifolds of dimension two
with a couple of three dimensional heteroclinic manifolds between them. These
heteroclinic manifolds are foliated by heteroclinic connections between
tori located at the same energy levels. By means of the {\em impact map} we
prove the persistence of these objects under perturbation. In addition, we
provide sufficient conditions of the existence of transversal heteroclinic
intersections through the existence of simple zeros of Melnikov-like functions.
The heteroclinic manifolds allow us to define the {\em scattering map}, which
links asymptotic dynamics in the invariant manifolds through heteroclinic
connections. First order properties of this map provide sufficient conditions
for the asymptotic dynamics to be located in different energy levels in the
perturbed invariant manifolds. Hence we have an essential tool for the
construction of a heteroclinic skeleton which, when followed, can lead to the
existence of Arnol'd diffusion: trajectories that, on large time scales,
destabilize the system by further accumulating energy. We validate all the
theoretical results with detailed numerical computations of a mechanical system
with impacts, formed by the linkage of two rocking blocks with a spring
Assessing the value dimensions of social enterprise networks
Purpose
Despite the importance gained by social enterprises (SEs) and the increased number of social enterprise networks (SENs) in the UK, there is a paucity of research into the role of these networks in enhancing the sector and creating value. The purpose of this paper is to provide empirical evidence assessing this value.
Design/methodology/approach
The assessment and insights were derived through a concurrent mixed method data collection strategy with 241 responses from members of SEs in the UK.
Findings
In terms of frequency, the use of SENs is still sporadic, denoting an immature stage of network lifecycle development. Moreover, it was identified that usage was affected primarily by the perceived usefulness of the information available. The ultimate value created was primarily of an informative nature rather than knowledge exchange.
Practical implications
A framework is developed describing the structure, content and interaction dimensions of value of SENs. The understanding of this value offers opportunities to shape government interventions and current practices of SENs in assisting SEs and providing an active, knowledge sharing community.
Originality/value
By exploring the value perceived by social entrepreneurs of being part of an SEN, the paper considered an under-researched area of SE literature that can maximised the impact of the sector
Widening the focus on informal entrepreneurship through the lens of intersectionality
The article explores the struggle of those involve with the entrepreneurial activities in the informal economy, within the challenging socio-economic environments. It investigates the extent to which intersectionality through structural, disciplinary, hegemonic and interpersonal power associated with poor, marginalised groups influence their entrepreneurial actions and rights collectively. Studies either view entrepreneurs through an informality lens, as marginalised populations engaged in low‐quality activities, or through a formality lens, as engaged in relatively higher quality entrepreneurial activities more as a necessity choice. The aim of this paper is to evaluate critically these explanations through intersectionality power in relation to waste pickers entrepreneurs in the informal sector in Colombia
"Fitting in" vs "standing out": How Social Enterprises Engage with Stakeholders to Legitimise their Hybrid Position
We investigate how social enterprises actively engage with their stakeholders to legitimise their hybrid position in addressing both social and businesses audience. This is particularly important in their effort to capturing stability (expectation to ‘fit in’) within an emerging field and at the same time to address change and growth (expectation to ‘stand out’) with their limited resources, in order to be profitable enterprises, while creating social value. We analyse in-depth interviews to senior members of twenty-one UK-based social enterprises, and we find that for many SEs involved in legitimisation exercise through the supportive system, collective system, and stakeholders' impression. By outlining the integrated framework on stakeholder engagement for hybrid legitimacy, we found that (i) legitimisation exercise through collective sharing of SE identity help to build SE image and legitimise SE socially driven mission, while (ii) legitimisation through supportive system (resources and business advantage) help building credibility by demonstrating SE capability to grow economically
Innovators intent: role of IT in facilitating innovative knowledge practices in social enterprises
With this paper we want to explore further the innovators intent, where social enterprises use imaginative ways to take advantage of information technology to create, share and manage the knowledge pool of their small enterprise. We draw on several perspectives on how information processing needs are addressed, as well as the manner in which IT enables and facilitates sense-making. Studies exploring the role of IT in organisations abound, however our focus is not large organisations but small social enterprises (SEs) and how they use IT to further their business objectives. Hence there is still a lack of understanding on how IT can support the management of knowledge within the context of SEs dealing with different contextual settings influenced by: constant tensions between social and economic objectives, more focus on sustainability than competiveness, limited resources, and high levels of democratic participation. All these conditions manifest themselves in SEs, aiming to tackle social problems, improve communities, people’s quality of life, and environment. To obtain a conceptual and empirical understanding of how IT can facilitate acquisition, conversion and application of knowledge in SEs, we conducted a qualitative study with 21 interviews to owners, senior members and founders of SEs in the UK, underpinned by findings from a quantitative survey with 432 responses. We found how IT was supporting informal practices of knowledge management in SEs, more the recovery and storage of necessary information in SEs, and less the collaborative work and communication among enterprise members. However, it was established that SEs were using different technologies, such as, cloud solutions and web 2.0 tools to manage informally their knowledge. The possible impediments for SEs to support themselves more on IT solutions can be linked mainly to economic and human constraints. These findings elucidate new perspectives of how small and hybrid organisations are supporting their operations using IT and the crucial role of cloud and web 2.0 tools in facilitating informal knowledge management practices
