Organizational and Innovative Flexibility Mechanisms and their Impact upon Organizational Effectiveness

This paper presents a lexical definition of firms' flexibility and its operationalization as used in the DISKO survey of 1900 Danish private firms. This operationalization is highlighted by data from a highly flexible firm which was visited in 1997 as part of a follow-up upon the questionnaire survey of which the firm in question was a part. The aim is to understand the flexible traits and their meaning for effectiveness. The analysis shows how the interviewees’statements give an understanding of the firm’s flexibility and its effectiveness and how their explanations draw upon elements from the operationalization as well as elements not included in the operationalization but can be seen as part of the lexical definition. The results point to the importance for effectiveness of the firm's culture based upon openness, cooperation and service mindednes in combination with a group structure which means extended cross functional information processes. These processes are supported by information and communication technology founded on a common understanding among the users building upon learning activities. From these connections stem extended relationships with customers and a rich web of processes conducive for new ideas on products and services. Details of these relationships are presented. From this analysis is also drawn a few conclusions regarding the problem of operationalization of flexibility. Results from the questionnaire survey are given as background information and include the distribution of the 1900 firms as measured by a flexibility index and divided according to a typology of static, flexible, innovative and dynamic firms.Flexibility, innovation, effectiveness

Ranking Competencies for Software Developers in Thailand

The purpose of this study was to prioritize/rank 12 existing software developer competencies and to find the pattern correlation among these competencies. A survey was designed to elicit responses from a target group (N=350) of software developers, system analysts, lecturers in Information and Communication Technology (ICT), ICT managers and others related to software industry (e.g. information technologist, software architect, computer technicians) in 14 organizations in Thailand. The return rate was 80.57% or 282 out of 350. Data was analyzed using descriptive statistics. Factor analysis was used to identify correlations among the 12 competencies. The 12 competencies were previously identified in a study of competencies for software developers in Thailand. The ranking was as follows: expertise; teamwork; logical thinking; system thinking; relation and communication; creative thinking; achievement; future thinking; emotion and ethic; flexibility; service mind; leadership and influence. In terms of correlations Future Thinking; System Thinking Relation & Communication; Teamwork are correlated. The second set of correlated factors are as follows: Leadership & Influence; Expertise; Emotion & Ethic; Flexibility. This research was limited to an investigation of competencies for software developers in Thailand only

Municipal-academic partnerships for innovation in sanitation delivery: a case study in Durban, South Africa

Service delivery for the diverse communities of eThekwini Municipality requires innovative solutions. The partnership between the Pollution Research Group (PRG) at the University of KwaZulu-Natal (UKZN) and eThekwini Water and Sanitation (EWS) began informally in the 1960s and was first formalised in 2006. The Memorandum of Agreement (MoA) between the two organisations included a retainer that allowed greatly flexibility than would have been possible with project-to-project funding. This allows the PRG to act as an in-house research and development team for EWS and gives the PRG access to numerous research sites. The partnership has led to global recognition for progressive policies and innovative service delivery. It has benefited from interdisciplinary research, trust between organisations and individuals that is built on open and transparent communication, and strong leadership. EWS and the PRG are keen to support similar municipal-academic partnerships across Africa to support locally relevant applied sanitation research

Service user perspectives of an early intervention in psychosis service: a service evaluation

This evaluation aimed to gather the perspectives of individuals accessing an early intervention in psychosis service (EIPS), in order to inform service development.Individual interviews (n=9) and one focus group (n=7) were conducted. Discussions focused on open questions pertaining to Service Users’ (SUs) experiences of accessing the EIPS. The results were analysed using inductive thematic analysis.Inductive thematic analysis was used and three main themes were generated; Consistency and Communication, facilitating therapeutic relationships between EIP service staff and SU’s. Pushing Boundaries, relating to the importance of services taking a graded approach to developing therapeutic relationships and (re)engaging in activities; and Normalising and Validating experiences of psychosis. Participants emphasised the importance of relationships with EIP service staff and fellow SUs and highlighted how SUs can feel fearful and vulnerable when staff are not accessible or they view their care as inconsistent. Participants further emphasised the need for practitioners to balance an approach that de-stigmatises psychotic experiences whilst validating distress.Consistency of support from EIP services can be as important as flexibility. Clinicians should carefully consider the balance between validating and normalising distressing experiences associated with Psychosis. Offering social activities with other SUs can facilitate therapeutic relationships and recovery but the results suggest that this should be facilitated in a graded way

Implementation of the Needs Assessment Tool for Interstitial Lung Disease Patients (NAT:ILD): Facilitators and Barriers

A Needs Assessment Tool (NAT) was developed previously to help clinicians identify the supportive/palliative needs of people with interstitial lung disease (ILD) (NAT:ILD). This letter presents barriers and facilitators to clinical implementation. Data from (1) a focus group of respiratory clinicians and (2) an expert consensus group (respiratory and palliative clinicians, academics, patients, carers) were analysed using Framework Analysis. Barriers related to resources and service reconfiguration, and facilitators to clinical need, structure, objectiveness, flexibility and benefits of an ‘aide-memoire’. Identified training needs included communication skills and local service knowledge. The NAT:ILD was seen as useful, necessary and practical in everyday practice

Reconfigurable Security: Edge Computing-based Framework for IoT

In various scenarios, achieving security between IoT devices is challenging since the devices may have different dedicated communication standards, resource constraints as well as various applications. In this article, we first provide requirements and existing solutions for IoT security. We then introduce a new reconfigurable security framework based on edge computing, which utilizes a near-user edge device, i.e., security agent, to simplify key management and offload the computational costs of security algorithms at IoT devices. This framework is designed to overcome the challenges including high computation costs, low flexibility in key management, and low compatibility in deploying new security algorithms in IoT, especially when adopting advanced cryptographic primitives. We also provide the design principles of the reconfigurable security framework, the exemplary security protocols for anonymous authentication and secure data access control, and the performance analysis in terms of feasibility and usability. The reconfigurable security framework paves a new way to strength IoT security by edge computing.Comment: under submission to possible journal publication

Architectures for smart end-user services in the power grid

Abstract-The increase of distributed renewable electricity generators, such as solar cells and wind turbines, requires a new energy management system. These distributed generators introduce bidirectional energy flows in the low-voltage power grid, requiring novel coordination mechanisms to balance local supply and demand. Closed solutions exist for energy management on the level of individual homes. However, no service architectures have been defined that allow the growing number of end-users to interact with the other power consumers and generators and to get involved in more rational energy consumption patterns using intuitive applications. We therefore present a common service architecture that allows houses with renewable energy generation and smart energy devices to plug into a distributed energy management system, integrated with the public power grid. Next to the technical details, we focus on the usability aspects of the end-user applications in order to contribute to high service adoption and optimal user involvement. The presented architecture facilitates end-users to reduce net energy consumption, enables power grid providers to better balance supply and demand, and allows new actors to join with new services. We present a novel simulator that allows to evaluate both the power grid and data communication aspects, and illustrate a 22% reduction of the peak load by deploying a central coordinator inside the home gateway of an end-user

Using real options to select stable Middleware-induced software architectures

The requirements that force decisions towards building distributed system architectures are usually of a non-functional nature. Scalability, openness, heterogeneity, and fault-tolerance are examples of such non-functional requirements. The current trend is to build distributed systems with middleware, which provide the application developer with primitives for managing the complexity of distribution, system resources, and for realising many of the non-functional requirements. As non-functional requirements evolve, the `coupling' between the middleware and architecture becomes the focal point for understanding the stability of the distributed software system architecture in the face of change. It is hypothesised that the choice of a stable distributed software architecture depends on the choice of the underlying middleware and its flexibility in responding to future changes in non-functional requirements. Drawing on a case study that adequately represents a medium-size component-based distributed architecture, it is reported how a likely future change in scalability could impact the architectural structure of two versions, each induced with a distinct middleware: one with CORBA and the other with J2EE. An option-based model is derived to value the flexibility of the induced-architectures and to guide the selection. The hypothesis is verified to be true for the given change. The paper concludes with some observations that could stimulate future research in the area of relating requirements to software architectures

Models for online, open, flexible and technology enhanced higher education across the globe – a comparative analysis

Digital technology has become near ubiquitous in many countries today or is on a path to reach this state in the near future. Across the globe the share of internet users, for instance, has jumped in the last ten years. In Europe most countries have a share of internet users near to or above 90% in 2016 (last year available for international comparisons), in China the current share is 53%, but this has grown from just 16% in 2007, even in Ethiopia the share has grown from 0.4% to 15.4% in the same period (data from ITU). At the same time expectations of widespread adoption of digital solutions in higher education have been rising. In 2017 the New Media Consortium’s Horizon Report predicted that adaptive learning would take less than a year to be widely adopted (Adams Becker et al., 2017). And projects such as ‘Virtually Inspired’ are showcasing creative examples of how new technologies are already being harnessed to improve the quality of teaching and learning. Furthermore, discussion of the United Nations’ Sustainable Development Goals emphasise the key potentials that digital technology holds for achieving the goals for education in 2030 (UNESCO, 2017). These developments lead university and college leadership to the question of how they should position their institution. What type of digitalisation initiatives can be found practice beyond best practices and future potentials? This is the question that this study attempts to answer. It sets out to analyse how higher education providers from across the world are harnessing digitalisation to improve teaching and learning and learner support and to identify emerging types of practice. For this, it focuses on the dimensions of flexibility of provision (in terms of time, place and pace) and openness of provision (in terms of who has access to learning and support and who is involved in the design of learning provision), as both of these dimensions can significantly benefit from integration of digital solutions. The method of information collation used by the study was a global survey of higher education institutions (HEIs) covering all world continents, more than thirty countries and 69 cases. The survey found that nearly three-quarters of all HEIs have at least one strategic focus and typologies were developed based on this analysis to group HEIs with similar strategic focuses. Overall, the findings suggest that most higher education providers are just at the beginning of developing comprehensive strategies for harnessing digitalisation. For this reason, the authors of this study believe that providers can benefit from the outcomes of this study’s research, as it can be used by university and college leadership for benchmarking similarities and differences and for cooperative peer learning between institutions. The database of cases and the guidelines for reviewing current strategies, which accompany this study, aim to facilitate this learning and evaluation process

Middleware Technologies for Cloud of Things - a survey

The next wave of communication and applications rely on the new services provided by Internet of Things which is becoming an important aspect in human and machines future. The IoT services are a key solution for providing smart environments in homes, buildings and cities. In the era of a massive number of connected things and objects with a high grow rate, several challenges have been raised such as management, aggregation and storage for big produced data. In order to tackle some of these issues, cloud computing emerged to IoT as Cloud of Things (CoT) which provides virtually unlimited cloud services to enhance the large scale IoT platforms. There are several factors to be considered in design and implementation of a CoT platform. One of the most important and challenging problems is the heterogeneity of different objects. This problem can be addressed by deploying suitable "Middleware". Middleware sits between things and applications that make a reliable platform for communication among things with different interfaces, operating systems, and architectures. The main aim of this paper is to study the middleware technologies for CoT. Toward this end, we first present the main features and characteristics of middlewares. Next we study different architecture styles and service domains. Then we presents several middlewares that are suitable for CoT based platforms and lastly a list of current challenges and issues in design of CoT based middlewares is discussed.Comment: http://www.sciencedirect.com/science/article/pii/S2352864817301268, Digital Communications and Networks, Elsevier (2017
