Abstract

Purpose

The purpose of this paper is to consider the process of undertaking a Safeguarding Adult Review (SAR) from the perspective of an Independent Author and from an agency participating in one and to stimulate a debate on both the process and the culture of Safeguarding Adults Boards that commission them.

Design/methodology/approach

The author drew solely on his own experience as an Independent Author and member of an SAR Panel.

Findings

The finding of this paper is that Safeguarding Adults Board vary in their commissioning process for SARs and their expectations of the role of Independent Author and the SAR Panel.

Research limitations/implications

The paper is drawn from the experience of the author and is therefore subjective.

Practical implications

There are implications for the role of Independent Authors and the process by which SARs are commissioned and managed.

Originality/value

The author is not aware of similar consideration of the experience of an Independent Author or of an agency participating in a SAR.

Abstract

Purpose

The rotor in screw motor is driven to rotate by highly pressure difference of drilling fluid (DF), while rotor drives drill bit to break rocks. DF works in the volume cavity (VC) which exists between the stator and rotor (SAR), these process realizes the conversion from hydraulic energy to mechanical energy finally. In order to assure seal performance and output power reliability of VC in common hypocycloid screw motor (CHSM), it’s essential to survey SAR end-face profile.

Design/methodology/approach

In this article, based on the internal and external cycloid method given for SAR end-face of φ172 7/8-head LZ type CHSM, the interference among SAR is established based on the meshing model through theoretical equilibrium method (TEM). Last, the reasonable design value of SAR interference in TEM is verified with the hydraulic parameters test results.

Findings

The profile optimization that top-root part of rotor end-face profiles is replaced by elliptical-circular arcs (ECA) makes the transition area of tooth-top and tooth-root connect smoother than before. The reasonable interference of SAR in TEM is almost 0.16mm~0.22mm to ensure better sealing performance. Through the hydraulic test, the interference positive fluctuation or the number of SAR head reduces increase (starting-pressure-drop) SPD while negative fluctuations by contraries. Meanwhile, DF penetration also decreases the revolution speed with the SAR interference decreases. The less SAR head revolution speed is always below the more with the constant driving power and DF hydraulic drop. Ultimately, decreasing in overall-efficiency occurs for larger fluctuation of interference or or less interference among SAR.

Originality/value

The line type optimization and analysis in TEM for CHSM improves the motor seal and output performance, also has important application values simultaneously.

Abstract

Purpose

The purpose of this study is to investigate the design parameters of an optimal SAR satellite sensor on remote sensing missions. Synthetic aperture radar (SAR) satellite missions, with the advantages of using all weather conditions, repetition of a pass, high spatial resolution and adequate balance, can not only provide timely coverage in disaster areas but also environmental monitoring and accident assessment. It also provides resources. The product of images depicts the needs of government organizations not only before and after the crisis but also during the crisis. Therefore, low-cost SAR satellite loading efforts have begun with SAR satellites and key technologies.

Design/methodology/approach

Information about the basic parameters of SAR satellites such as antenna dimensions, image resolution, pulse and relationship repetition, as well as the tradeoff between required parameters and design needs’ evaluation was achieved. In this paper, the tradeoff methods between some technical requirements are presented, and the limitations in the design of a SAR prototype sensor in the X band are examined. Diagrams can provide a complete overview of the predicted fluctuations and tradeoffs between them for a designer.

Findings

Analysis of findings reveals that data transmission rate with PRFmin is independent of antenna incidence angle, but in contrast, it is dependent on PRFmax, and afterward its relationship was analyzed. Drawn diagrams approved presented design and calculations. Other important parameters in the design of the SAR sensor such as antenna dimensions, tilt angle, amplitude and resolution of azimuth can be achieved as significant elements in systematic design according to the results of this paper. Regarding the displayed diagrams, it can be understood that the angle of the antenna should not be from 15 to 60 degrees.

Originality/value

This paper provides an overview of the new observational capability offered by the second generation of SAR sensors, especially in the field of remote sensing applications. The built-in antenna is built for the small SAR sensor. This array antenna is designed with a parallel screen to work in X-frequency with vertical polarity.

Abstract

Purpose

The assessing of the specific absorption rate (SAR) of living organisms or phantoms is difficult to realize and this paper seeks to do this. SAR much more precisely describes the energy absorbed by biological objects than values of electric field strength (E [V/m]) or power density (S [W/m2]) measured at the point of exposition. However, for living objects the assessing of SAR is not an easy task by measuring methods or even in calculation evaluations. Numerical techniques, especially the finite‐difference time‐domain method (FDTD), offer different possibilities of calculations. The important problem with FDTD method introduced to lossy objects with complex shapes is that this method is not verified with the measuring data.

Design/methodology/approach

In this work the results of calculations and measuring data of ellipsoidal phantoms filled with specimen of electrical parameters like muscle tissue are presented. The calculations of SAR have been realized for two cases, e.g. for plane wave incident and for waveguide condition. Measurements for verifying the obtained data were done by waveguide method. The comparison of numerical (the package CONCERTO (Vector Fields Ltd)) and measurement methods were done at frequencies 900 and 1,800 MHz.

Findings

Calculations of SAR of lossy objects by FDTD method have been confirmed by measurements and analytical method of calculations. This documents that the package CONCERTO (Vector Fields Ltd) (Concerto User Guide) can be used for such calculations.

Originality/value

This paper presents the results of calculations of SAR of ellipsoidal phantoms filled with specimens of electrical parameters of equivalent muscle tissue.

Abstract

Purpose

The purpose of this paper is to analyse if the classification system introduced by International Search and Rescue Advisory Group (INSARAG), or INSARAG External Classification (IEC), contributes to effective international search and rescue (SAR) activities in the 2015 Nepal earthquake.

Design/methodology/approach

In addition to the data collected by Office for the Coordination of Humanitarian Affairs and the United Nations Disaster Assessment and Coordination (UNDAC) team, the data were collected by one of the authors who was deployed to Nepal as part of the UNDAC just after the earthquake. Interviews with the deployed international SAR teams and the INSARAG Secretariat were also conducted.

Findings

Although more than 50 teams have been classified in IEC, some IEC-classified teams could not utilise their full capabilities in the Nepal response. For example, they did not necessarily arrive in Nepal earlier than the non-classified teams, but it was because the affected country did not prioritise the IEC-classified teams. To save more lives by international teams, INSARAG will need to raise the awareness of IEC in receiving countries, consider the good regional balance of IEC-classified teams and facilitate strengthening local SAR capabilities through the IEC process.

Originality/value

The added value of this study is, by combining the evidence-based field reality and academic analysis, to find out the existing problems in the field and to provide tangible recommendations for further improvement of the IEC system, which will then lead to saving more lives.

Abstract

Purpose

The purpose of this paper is to provide background information on a rarely studied response capability of communities across the USA, local, mostly volunteer search and rescue (SAR) teams.

Design/methodology/approach

Information on local teams was collected from January 2005 until February 2006 through internet searches, online SAR organization lists, and by e‐mailing a survey to local teams. A smaller, previously used database was used to verify the final list of teams and 57 new teams were added in this manner. An SPSS database was created using all the fields collated from the survey.

Findings

It was found that there are 1,150 teams in the USA, which range from one team per State to 79 teams in California. Local SAR teams had a quicker response time than federal teams, while maintaining better equipment and training than emergent volunteers. These teams, unlike the federally funded US&R teams, rely mostly on donations and community fundraisers to continue operating.

Research limitations/implications

Missing data were the most consistent problem faced. Web sites, web links and e‐mail addresses often had expired or did not contain the right information, some teams existed without having a web site (and therefore were not included in the database); also response to the e‐mail survey was low.

Practical implications

Integrating interested local SAR teams into official multi‐organizational disaster and emergency responses could provide valuable additional resources to emergency and incident managers, would allow for better funding for local SAR, and could facilitate recognition to these often overlooked teams.

Originality/value

This paper provides preliminary information on local SAR teams in the USA.

Abstract

Purpose

There are many types of the ADCs implemented in the mobile and wireless devices. Most of these devices are battery operated and operational at low input voltage. SAR ADC is popular for its low power operations and simple architecture. Scientists are still working to make its working faster under the same low power area. There are many SAR-ADC implemented in the past two decades, but still, there is a big room for dual SAR-ADC.

Design/methodology/approach

The authors are presenting a dual SAR-ADC with a smaller number of components and blocks. The proposed ultra-low-power circuit of the SAR-ADC consists of four major blocks, which include Bee-bootstrap, Spider-Latch dual comparator, dual SAR-logic and dual digital to analog converter. The authors have used the 90-nm CMOS library for the construction of the design.

Findings

The power breaks down of the comparator are dramatically improved from 0.006 to 0.003 uW. The ultimate design has 5 MHz operating frequency with 25 KS/s sampling frequency. The supply voltage is 1.2 V with 35.724 uW power consumption. Signal-to-noise and distortion ratio and spurious-free dynamic range are 65 and 84 dB, respectively. The Walden's figure of merits calculated 7.08 fj/step.

Originality/value

The authors are proposing two-in-one circuit for SAR-ADC named as “dual SAR-ADC”, which obeys the basic equation of duality, derived and proved under the heading of proposed solution. It shows a clear difference between the performance of two circuit-based ADC and one dual circuit ADC. The number of components is reduced by sharing the work load of some key components.

Abstract

Purpose

The purpose of this study is to identify the competencies required of Shari’ah auditor (SAR) in the Islamic banking environment.

Design/methodology/approach

A qualitative approach using a multiple-case study through the semi-structured interview was used. Data was gathered from a representative of Central Bank of Malaysia, and 30 other respondents consist of the Head of Shari’ah audit (HSA) and SAR from four types of banking institutions. A focus group discussion was later conducted to validate the model of competency proposed.

Findings

Results show a mixed practice on the recruitment of SAR. Most banking institutions prefer to use their existing internal auditors as opposed to recruiting fresh graduates or acquire experienced SAR from other financial institutions. Knowledge in Shari’ah, Islamic banking and Fiqh Muamalat is considered as the essential knowledge component for SAR, while auditing is revealed as the core skill that SAR should have to perform the Shari’ah audit effectively. The study also found that personal skills such as willingness to learn and teamwork as the complementing characteristics to the knowledge and skill components, as a package required for a competent SAR.

Research limitations/implications

The results of this study would have both theoretical and practical contributions to the regulatory bodies, academicians and professionals. Theoretically, this study made a concerted effort to enhance prior studies on the qualification aspect of Shari’ah audit literature, emphasizing the elements necessary to recruit competent SARs in the Islamic financial institutions (IFIs). The element of “time” has been infused to the existing effective job performance theory add dynamics to the model, recognizing the need for years of experience as part of elements necessary to become competent SAR. In practice, the competency model is recommended to the industry players in pooling competent talents in the Islamic finance industry (R4) and (B5). In spite of its limitation to confine only to the IFIs, it sheds light on human resource management within the Islamic organizations.

Practical implications

The study would contribute to the practitioners as a guideline to the Human Resource Department in recruiting their SAR and also for succession planning purposes.

Originality/value

A competency model for SAR was proposed focusing on building knowledge, core and personal skills that can be used as guidance in determining the criteria needed for a competent SAR, which is a new dimension for Islamic auditing literature. The sub-objective of determining the elements of competency, as well as understanding the current practice of recruiting the SAR became the input in the building of the competency model.

Abstract

Purpose

The author will describe the operational tasks of S.44’s statutory mandate: for example, commissioning the review; being responsive to the representatives of the relevant agencies concerned; securing pharmacological/medical advice; adding Ben’s death to the review; engaging with relatives; and ensuring that “lessons” were foregrounded. How the review was set up/recognising the standout features from the beginning/managing the situation when an agency is withholding information/“drip feeds” information into the review; navigating/steering the Safeguarding Adults Review (SAR) alongside other processes – police/inquest/Care Quality Commission.

Design/methodology/approach

This practice paper describes the experiences of coordinating a complex SAR into the deaths of three adults at Cawston Park Hospital in Norfolk.

Findings

The system insights that SARs give us prompt exploration of how to inject this learning into current discourse on how we better protect the most vulnerable in our communities.

Originality/value

The purpose of this paper is to explore the process and requirements of conducting a complex SAR from the perspective of a safeguarding adults board manager. It will be of interest to anyone who is involved in SARs, in particular safeguarding adult board chairs, board managers, members of SABs and SAR authors as management of SAR is one of the three statutory duties of a SAB.
