Strategy of state transfer for open quantum systems by no-knowledge feedback control: Via reverse engineering

It has long been interest to control the transfer of population between specified quantum states and protect the coherence of the system at the same time. In this paper, we investigate a scheme to improve the strategy of state transfer for open quantum systems using no-knowledge measurement-based feedback control and reverse engineering. In order to ensure that the system can process information effectively, we first design the control pulse in advance from the perspective of population and coherence and then verify it through numerical simulations. The research results show that, based on the designed control pulse, we can indeed drive the system from any initial state to the desired target state, and the coherence of the system can be effectively protected during the state transition.

Individual knowledge measurement: organizational knowledge measured at the individual level

Purpose Fundamental classifications of knowledge may be measurable as factors of production and can reveal evidence of specialization between adjacent stages of production even in the presence of shared substantive knowledge. This study of aims to distinguish between, and empirically measure, relative reliance on fundamental classifications of knowledge at the individual level. Design/methodology/approach In this study, investment managers were asked in an online survey to weigh their relative reliance on tacit, codified and encapsulated knowledge in executing different investment strategies for diverse client groups. Measures of relative reliance on each fundamental classification of knowledge were derived from weights assigned by each survey respondent in a series of six questions. Findings Survey respondents provided reliable measures of their relative reliance on tacit, codified and encapsulated knowledge. Reliance on these fundamental classifications of knowledge is shown to differ between investment managers, depending on the investment strategies being used and client groups served. These differences were exhibited notwithstanding all the respondents sharing common substantive knowledge. Research limitations/implications Measures of relative reliance on three classifications of knowledge were based on self-reported ratings rather than on objectively observed phenomena, making them subject to measurement error. Therefore, researchers are encouraged to observe relative reliance on tacit, codified and encapsulated knowledge in future studies. Originality/value The divergences in relative reliance on the fundamentally different knowledge-based factors of production were found in the presence of jointly held substantive knowledge, suggesting that fundamental classifications of knowledge are measurable and can provide evidence of specialization.

Disease-related knowledge measurement instruments of people affected by multiple sclerosis: protocol for a systematic psychometric review

IntroductionDisease-related knowledge is a key component of shared decision making and a relevant outcome to measure the effectiveness of information provision interventions. However, no systematic psychometric reviews have been found that assess the measurement instruments aimed at evaluating the disease-related knowledge of people affected by multiple sclerosis. This review aims to systematically assess the quality of the measurement properties of all available disease-related knowledge measurement instruments of people affected by multiple sclerosis.Methods and analysisA systematic psychometric review will be carried out in accordance with the guidelines proposed by the international ‘COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)’ initiative. Studies that meet the following criteria will be selected: (1) those whose aim is to measure disease-related knowledge, (2) those whose study populations are affected by multiple sclerosis and (3) those whose aims are to develop measurement instruments or evaluate one or more of their measurement properties. The information sources will be MEDLINE (via PubMed), CINAHL, PsycINFO and OpenGrey. The methodological quality will be assessed using the ‘COSMIN Risk of Bias’ checklist. Available evidence will be synthesised and graded using a modified Grading of Recommendations Assessment, Development and Evaluation approach.Ethics and disseminationAs this is a systematic review, no ethics approval is needed. Study findings will be shared with multiple sclerosis patient support groups and in reports to funders. The results will be submitted to a peer-reviewed journal and will be presented at national and international conferences.PROSPERO registration numberCRD42019125417.

INCREASING PUBLIC KNOWLEDGE ABOUT COVID-19 THROUGH DOOR TO DOOR CAMPAIGN

Based on COVID-19 monitoring data from the Indramayu District Health Office, there were 210 additional confirmed cases of COVID-19 on June 20, 2021. This number was the highest daily confirmed cases during the pandemic in Indramayu Regency, the data still increase until now. Of the total number of 9,795 confirmed cases, 1,179 people were still being treated, 8,353 had recovered and 263 had died. Based on observations, it was known that there were still many people who did not comply with the health protocols regulation. Therefore, education was needed so that public knowledge about the signs, symptoms, prevention and reporting flow of COVID-19 cases able to increase. The target of the activity was the head of RT and RW in Pekandangan Jaya Village, Indramayu District, Indramayu Regency. This activity aimed to determine the public knowledge change before and after being given education about COVID-19. The method of implementation was door to door to RT and RW houses using educational media in the form of posters for 3 days from 14 to 16 July 2021, held every 10.00 to 15.00 WIB, knowledge measurement was carried out by giving pre and post test questions. The results of providing education were known to increase public knowledge about signs and symptoms, prevention efforts and the flow of COVID-19 case reporting by 19%. It is known that 56.2% before being given counselling and 75.2% after being given counselling. Further community service is needed to measure changes in community behavior in Pekandangan Jaya Village.

The Effectiveness of Booklets in Stimulation, Detection and Early Intervention of Growth and Development (SDEIGD) for Health Cadres in Implementing the Growth and Development Screenings of Toddlers

The importance of monitoring the growth and development of early childhood is helpful for all parties involved, especially for Health Integrated Service (HIS), teachers, parents, and the children themselves. HIS is expected to determine what steps or efforts can be taken in helping children's development because from the family, in this case, the parents, the beginning of growth and development begins. The purpose of this study was to develop a Booklet of Stimulation, Detection and Early Intervention on Growth and Development (SDEIGD) for health cadres in the implementation of screening for growth and development of toddlers. This study involved 32 health cadres in the Aur Duri Public Health Center Jambi City working area as the intervention group and the Penyengat Olak Jambi Health Center as many as 32 people as controls. This research will be conducted in August 2019 at the Putri Ayu Public Health Center, Jambi City. There are two stages in this study, consisting of the instrument preparation stage and administrative preparation. The next stage is the implementation which consists of making booklets for Health integrated services cadres, enriching and developing the skills of Health integrated services cadres, small group discussions, practicum and simulation of the implementation of growth and development stimulation, early detection and screening of growth and development, early intervention on growth and development in children aged 0-6 years, and knowledge measurement. Data were analyzed using the Shapiro-Wilk test at a 95% confidence level (α ≤ 0.05). The results of the validation of materials experts and linguists, it is known that the SDEIGD booklet media meets the criteria and is worthy of being a guide for health cadres in understanding Stimulation, Detection, and Early Intervention of Toddler Development. The media trial starting from small groups, large groups and understanding tests of SDEIGD material indicate that the SDEIGD Media Booklet is worthy of being a handbook for health cadres for the implementation of screening for toddlers growth and development.

Response Options and the Measurement of Political Knowledge

By many measures, the public knows little about politics. But just how little people seem to know depends on the questions that are put to them. In particular, knowledge levels seem higher when people are asked closed- rather than open-ended questions. In turn, differences between estimated knowledge levels are sometimes attributed to fundamental differences between these types of questions. Building on this previous research, the present study uses a pre-registered experiment conducted with a representative national sample to shed new light on the relationship between question form and knowledge measurement. The authors find that inferences about political knowledge depend less on fundamental differences between open- and closed-ended questions than on two little-appreciated aspects of survey design: the number and difficulty of the response options that accompany closed-ended questions. These aspects of survey design have large effects. Scholars who use the same questions with different response options may reach substantively different conclusions about the public's levels of knowledge.

Improving parameter precision of estimation by no-knowledge feedback control

We investigate a scheme to improve the precision of parameter estimation using no-knowledge measurement-based feedback control. The scheme shows that combination of no-knowledge measurement-based feedback control and quantum weak measurement is the optimal way to suppress decoherence. Our results indicate that compared with knowledge quantum feedback control, under the same weak measurement condition, the precision of parameter estimation can be improved more effectively with no knowledge quantum feedback control. Further, based on numerical simulation, we find that the feedback operator is chosen as [Formula: see text] (or both [Formula: see text] and [Formula: see text], which can protect quantum Fisher information (QFI) for a long time.

Performance Indicators of Enterprises as Systems at the Micro Level: An Updated Paradigm in the Context of «Structure – System»

The article is aimed at outlining the possibilities of applying the conception of structuralism in order to interpret the indicators of the components (constituents) of the efficiency of enterprises as micro level systems in terms of the paradigm of «structure – system» taking into account the history of the origin and development of the mentioned conception. The article presents the results of a study of the evolution of concepts «structure» and «system» in the context of the relevant paradigm in view of improving approaches to management of the performance of enterprises. The interpretation of the above mentioned definitions by different scholars is provided; the author’s own interpretation of the concepts of «structure of performance indicators» and «system of constituent performance indicators» of enterprises activity are proposed. Methodological approaches to managing the performance of enterprises as complex micro level systems based on the above mentioned system of indicators based on the models of Burennikova (Polishchuk) – Yarmolenko are outlined. The structural-logical scheme of basic concepts in the paradigm of «structure – system» is proposed. The «model of interrelation» between the concepts of «structure» (quantitative and qualitative constituents of performance indicators) and «system» (as a multiplex, a set of interrelated elements, a complex of related performance indicators) is presented in a systematic approach of scientific cognition in order to more clearly identify the relationships between the studied concepts and related indicators with taking into account the system approach. It is emphasized that the lack of results of computations on certain components (constituents) of the specified system of indicators makes it impossible to create a holistic picture regarding the performance of enterprises. It is underlined that the improved by the author methodology of knowledge, measurement and evaluation of the performance of enterprises will contribute to improving their management and finding reserves for the development of enterprises as systems.
