Low-overhead Hardware Supervision for Securing an IoT Bluetooth-enabled Device: Monitoring Radio Frequency and Supply Voltage

Over the past decade, the number of Internet of Things (IoT) devices increased tremendously. In particular, the Internet of Medical Things (IoMT) and the Industrial Internet of Things (IIoT) expanded dramatically. Resource restrictions on IoT devices and the insufficiency of software security solutions raise the need for smart Hardware-Assisted Security (HAS) solutions. These solutions target one or more of the three C’s of IoT devices: Communication, Control, and Computation. Communication is an essential technology in the development of IoT. Bluetooth is a widely-used wireless communication protocol in small portable devices due to its low energy consumption and high transfer rates. In this work, we propose a supervisory framework to monitor and verify the operation of a Bluetooth system-on-chip (SoC) in real-time. To verify the operation of the Bluetooth SoC, we classify its transmission state in real-time to ensure a secure connection. Our overall classification accuracy is measured as 98.7%. We study both power supply current (IVDD) and RF domains to maximize the classification performance and minimize the overhead of our proposed supervisory system.

Social process in a voluntary organisation: a study of adult membership in the Scout Association of New Zealand

<p>This thesis examines social processes in a large, voluntary organisation. The investigation was concerned with the activities and retention of lower-level adult members in the Scout Association of New Zealand. The demographic, socio-economic and organisational background of members, their attitudes, and the organisational context within which activity occurs were examined with reference to the relationship of these variables with the satisfaction, commitment and participation of members. Particular attention was given to five organisational variables: size, communication, control, support and effectiveness. Attitudinal variables such as solidarity, ideology, prestige and orientation were also examined. It was found that the organisational variables were most clearly related to differences in satisfaction, commitment and participation. This was described firstly in terms of an association between larger size, better and more frequent communication, and higher levels of control, support, and effectiveness. The latter in turn was related to higher levels of satisfaction, commitment, and participation. Background variables, particularly age, also proved important. This suggested that the life cycle plays a part in voluntary association membership and activity. It was concluded that the main organisational variables are affected by the peripheral structural position of voluntary associations in New Zealand society. The sanctions available to senior officials are few and generally weak, and there is often little pressure to pursue some of the more intangible formal goals. Adherence to official procedures varies, with frequent blockages of control, communication and support. This results in considerable differences in the organisational environment within which members operate. The study was carried out over two years. Observation, semi-structured and unstructured interviews were used, as well as a lengthy questionnaire.</p>

Media features and communication control in the digitalized workplace: a study about regulating negative emotional communication

PurposeOne challenge facing the digitalized workplace is communication control, especially emotion regulation in which individuals try to manage their emotional experiences and/or expressions during organizational communication. Extant research largely focused on the facilitating role of a few media features (e.g. fewer symbol sets). This study seeks to provide a deeper understanding of media features that individuals, as receivers of negative emotions expressed by communication partners, could leverage to support regulating negative emotional communication in the workplace.Design/methodology/approachThis study used qualitative research methods to identify media features that support regulating negative emotional communication at work. Data were collected using interviews and was analyzed using directed content analysis in which media features discussed in media synchronicity theory (MST) were used as the initial coding schema but the researcher was open to media features that do not fit with MST.FindingsIn addition to media features (and capabilities) discussed in MST, this study identified five additional media features (i.e. message broadcasting, message blocking, receiving specification, recipient specification and compartmentalization) and two underlying media capabilities (i.e. transmission control capability and participant control capability) that may support regulating negative emotional communication. Two major mechanisms (i.e. reducing or eliminating emotion regulation workload, and providing prerequisites or removing obstacles for emotion regulation) via which media features support emotion regulation were also identified.Originality/valueThis paper provides a more comprehensive understanding regarding communication media features that may support emotion regulation in particular and communication control in general. Findings of this study contribute to several literatures and may also transfer to other similar contexts.

Insights into Barriers and Educational Needs for Farm Succession Programming

Planning for farm succession is vital to the longevity of the farm business. To understand the challenges with succession planning, the University of Wisconsin - Division of Extension facilitated focus group meetings across the state. These authors classified the information from the focus groups into eight codes, and each code was further subdivided into themes. The codes included Financial, Communication, Control, Change, Fair vs. Equal, Delivery, and Support, Strategies, and Educational Needs. University of Wisconsin Division of Extension Agriculture Educators utilized the information obtained from the focus groups to create a workbook that provides practical assistance when working with families planning a farm succession.

Organizational Communication Study: Organizational Control Theory Implementation by HMI Purwokerto Branch in the Omnibus Law Demonstration

This study aims to examine the organizational communication control strategy carried out by the Purwokerto Branch of the Islamic Student Association (HMI) to demonstrate the Ratification of the Job Creation Bill (Omnibus Law). The method used is descriptive qualitative using organizational control theory as a theoretical framework. The results showed that the involvement of the Purwokerto Branch of HMI in the Omnibus Law demonstration was a critical intellectual movement that arranged forward a constitutional approach. The simple control aspect is implemented through a three-layer communication mechanism. The solidarity of members towards the three layers of communication constructs communication conduct harmoniously. HMI uses two technical tools for technical control, specifically communication aids and internal identification tools as non-verbal symbols of the organization. There are strict controls to identify members in the demonstration through the symbol. Regarding bureaucracy, this organization prioritizes communication with local authorities regarding the fulfillment of formal rules before holding a demonstration. In addition, organizational procedures are also carefully considered, especially regarding consolidating the organization’s internal communications. Conservative control is implemented by strengthening interpersonal communication with active members or alumni networks spread across various professions. The organizational communication control strategy of the HMI Purwokerto Branch focuses on the harmonization of demonstrations that prioritize aspirational and implementation communication by emphasizing a constitutional approach.
