Reading and writing is modelled in CSP using actions containing the sym- bols ? and !. These reading and writing actions are synchronous and there is a one- to-one relationship between occurrences of pairs of these actions. It is cumbersome to ease the restriction of synchronous execution of the read and write actions. For this reason we introduce the half-asynchronous parallel operator that acts on actions con- taining the symbols ¿ and ¡ and study the impact on a Vertex Removing Synchronised Product.

Nonprofit organizations (NPOs) have deployed various strategies in motivating businesses to source sustainably, such as the co-development and promotion of sustainability certification and direct collaboration in cross-sector partnerships (CSPs). This is an important current-day priority, given the ambitions set out in the Sustainable Development Goals (SDGs). Increasingly, NPOs have taken up a role as conveners of such CSPs. Research on CSPs has, to date, often considered conveners as a ‘resource’ to the CSP, contributing to its effectiveness. In this study, we shift the focus towards the convener by considering a case of a ‘mission-driven convener’, an NPO that initiates CSPs as a strategy to realize its own sustainability objectives. Our explorative case study—comparing the NPO’s efforts across six countries in setting up national coffee platforms—reviews the concept of a mission-driven convener vis-à-vis established notions on convening and identifies which strategies it applies to realize a CSP. These strategies comprise productively combining certification-driven efforts with CSPs, combining process and outcomes of CSPs, and drawing on cross-level dynamics derived from outsourcing of convening work to local actors. With our study, we contribute to research on CSP conveners by offering an alternative interpretation to the relation between the CSP and the convener, attributing more agency to the convener as a mission-driven organization. Strengthening our understanding of CSPs and conveners is an important means to advance the Sustainable Development Goals (SDGs).

Reading and writing is modelled in CSP using actions containing the symbols ? and !. These reading actions and writing actions are synchronous, and there is a one-to-one relationship between occurrences of pairs of these actions. In the CPA conference 2016, we introduced the half-synchronous alphabetised parallel operator X ⇓ Y , which disconnects the writing to and reading from a channel in time. We introduce in this paper an extension of X ⇓ Y , where the definition of X ⇓ Y is relaxed; the reading processes are divided into sets which are set-wise asynchronous, but intra-set-wise synchronous, giving full flexibility to the asynchronous writes and reads. Furthermore, we allow multiple writers to the same channel and we study the impact on a Vertex Removing Synchronised Product. The advantages we accomplish are that the extension of X ⇓ Y gives more flexibility by indexing the reading actions and allowing multiple write actions to the same channel. Furthermore, the extension of X ⇓Y reduces the end-to-end processing time of the processor or coprocessor in a distributed computing system. We show the effects of these advantages in a case study describing a Controlled Emergency Stop for a processor-coprocessor combination.

Reading and writing is modelled in CSP using actions containing the symbols ? and !. These reading actions and writing actions are synchronous, and there is a one-to-one relationship between occurrences of pairs of these actions. In the CPA conference 2017, we introduced the extended half-synchronous al- phabetised parallel operator X ⇕ Y , which disconnects the writing to and reading from a channel in time; the reading processes are divided into sets which are set-wise asynchronous, but intra-set-wise synchronous, giving full flexibility to the reads. In this paper, we allow multiple writers to write to the same channel set-wise asynchronously, but intra-set-wise synchronously and we study the impact on our (Extended) Vertex Removing Synchronised Product. The advantages we accomplish are that the extension of X ⇕ Y gives more flexibility by indexing the writing actions and the reading actions, leading to a straightforward majority vote design. Furthermore, the extension of X ⇕ Y preserves the advantages of the X ⇕ Y operator.

Strengthening sustainability in global supply chains requires producers, buyers, and nonprofit organizations to collaborate in transformative cross-sector partnerships (CSPs). However, the role played by nature in such partnerships has been left largely unattended in literature on CSPs. This article shows how strategizing nature helps CSPs reach their transformative potential. Strategizing nature entails the progressive revealing and reconciling of temporal tensions between “plants, profits, and people.” We show how a CSP took a parallel approach—recognizing the divergent temporalities of plants, people, and profits as interlaced and mutually determined—toward realizing their objective of implementing living wages in a sub-Saharan African country’s the tea industry, simultaneously driven by the revitalization of tea plantations. The promise of better quality tea leaves allowed partners to take a “leap of faith” and to tackle pressing issues before the market would follow. Our findings thus show the potential of CSPs in driving regenerative organizing.

The role of conveners in initiating and/or leading the formation of cross-sector partnerships (CSPs) has received ample attention in the literature on partnership formation. However, what happens when two organizations jointly take up this role? This question is important in many complex partnerships, such as those on sustainable supply chains. We present a qualitative, longitudinal case study explaining how two organizations together convened the formation of a complex cross-sector partnership, and emphasize the changing roles of each organization individually and their shared relationship over time. We analyze how this process of ‘collective convening’ unfolded, how it impacted the collaboration, and how the conveners coped with the tensions brought about by the constellation of collective convening. These tensions manifested at the interorganizational level in the relationship between the two conveners, but were also fed by each convener’s organizational level dynamics, as these dynamics influenced the collective convening process. A paradox perspective is appropriate to analyze the tensions emerging from the collective convening process and the ensuing organizational response strategies. We contribute to the literature on CSPs by introducing and elaborating on the notion of ‘collective convening’, which reflects a reality in complex CSP formation but has remained largely unstudied in the existing literature on convening. Further, we show how conveners bring their organizational level dynamics to the interorganizational level and how these dynamics influence the CSP formation process in positive and negative ways.

In this paper, the performance gain obtained by combining parallel peri- odic real-time processes is elaborated. In certain single-core mono-processor configurations, for example, embedded control systems in robotics comprising many short processes, process context switches may consume a considerable amount of the available processing power. For this reason, it can be advantageous to combine processes, to reduce the number of context switches and thereby increase the performance of the application. As we consider robotic applications only, often consisting of processes with identical periods, release times and deadlines, we restrict these configurations to periodic real-time processes executing on a single-core mono-processor. By graph-theoretical concepts and means, we provide necessary and sufficient conditions so that the number of context switches can be reduced by combining synchronising processes.

USE conference paper.Ever since the mid-1970s a multitude of studies linking corporate sustainability performance (CSP) measures and financial performance measures have been conducted. Until today a plethora of corporate sustainability performance measures heve been developed. A universally accepted CSP definition of construct does not (yet) exist. Since we don't exactley know what CSP entails, CSP measures should (at least) be considered conceptually flawed for that matter. These measures may measure CSP, but it cannot e excluded that other (overarching) phenomena are measured. There are leads suggesting that CSP measures are reflections or representations of corporate culture, suggesting that corporate culture drives FP. If so, managers should not focus on increasing CSP to boost FP, but create a high culture for sustainability If corporate culture drives financial performance, the investment community can also benefit through improving its decision making processes by including CSP measures that reflect corporate culture.

This article extends the corporate social performance (CSP) model by studying the role of governance structures and governance systems in shaping corporate social responsibility. The authors argue that a governance perspective offers a fruitful research strategy both to study empirically how firms balance the competing moral frameworks and political philosophies that are part and parcel of defining their role in society and to further the theoretical integration of the descriptive and normative perspectives in the business and society field. They illustrate the potential of this research strategy with a comparative case study of processes of responsiveness at four Dutch banks with markedly different governance structures. This study shows how governance systems and structures both enable and constrain corporate responsibility and responsiveness. The authors conclude with a proposal to reorient the CSP model to harness the integrative potential of studying corporate social responsibility through a governance lens.
