Rate-Adaptive Concatenated Multi-Level Coding With Novel Probabilistic Amplitude Shaping

This paper proposes a new probabilistic amplitude shaping (PAS) approach for concatenated two-level multi-level coding (MLC). The proposed system is based on a concatenated forward error correction (FEC) scheme where outer codes are serially concatenated with inner two-level MLC. This concatenated two-level MLC scheme has recently been shown to have a potential for achieving better performance-complexity trade-offs than the conventional bit-interleaved coded modulation (BICM). Meanwhile, PAS has recently been demonstrated to offer remarkable performance gains as well as rate adaptivity. However, the majority of existing works on PAS assume the use of the binary reflected Gray code as a bit-labeling, and its application to coded modulation schemes with other bit-labelings, such as two-level MLC, may not be straightforward. In this paper, we devise a bit-labeling scheme and propose a new PAS structure for an efficient integration of PAS with two-level MLC systems. More specifically, we propose to generate signed amplitude symbols with the distribution matcher (DM) for maximizing both coding and shaping gains achieved by two-level MLC and PAS, respectively, while the conventional PAS generates unsigned amplitude symbols. It is demonstrated by simulation results that, with 256QAM and inner polar codes, the proposed two-level MLC with PAS simultaneously offers 75% reduction in the number of required inner encoding and soft-decision (SD) decoding operations for given outer and inner FEC code lengths, and up to 0.3 dB performance gain over the conventional PAS scheme.
Optimal Dispatch Coordinating Power Generation With Carbon Emission Permit for Wind Farms Integrated Power Grid Considering Demand Response

To meet the requirement of energy conservation and emission reduction,a novel optimal dispatching model is proposed and the approach to solve the proposed model is given.Three power generation modes,i.e.,thermal power generation,wind power generation and demand response(DR) that is regarded as virtual power generation are taken as research objects.Both wind farms and DR are non-emission resources,besides DR can provide spinning reserve and improve the utilization of wind power to reduce carbon emission evidently.The proposed model is based on multi-object unit commitment model in which the dispatching mode that coordinates power generation with carbon emission permit is adopted to seek a compromise-coordination solution;various constraints in the proposed model such as DR,security constraints and carbon emission are synthetically considered.Using piece-wise linearization,the proposed model is solved by mixed integer linear programming(MILP). The solution approach being used is practicable and suitable to large-scale power grid.Simulation results of IEEE 30-bus system show that both carbon emission permit and generation cost can be taken into account;simulation results of IEEE 118-bus system show that with the increase of rated output of wind farm both carbon emission cost and unit operation cost are reduced,and obvious economic effect,energy conservation and carbon emission reduction can be achieved while the proposed dispatching mode coordinating power generation with DR is applied.
Developing inclusive and healthy organizations by employing designated lived experience roles: Learning from human resource management innovations in the mental health sector

Abstract Employees’ mental health issues present significant challenges for organizations globally. Despite various human resource management (HRM) interventions, systemic stigmatization of people with mental health challenges endures. We propose drawing on an innovative HRM practice in the mental health sector, by introducing designated lived experience (LE) roles into organizations to achieve cultural shifts that benefit the entire workforce. A sector-wide survey was conducted across the mental health sector within an Australian state. A whole-workforce approach was taken by seeking perspectives from employees in both LE roles and traditional roles. Complete responses were obtained from 327 participants (116 in LE roles and 211 in traditional roles). Results showed that across the entire workforce, top leader commitment to LE roles led to more clarity about LE roles, resulting in improved individual outcomes of authentic self-expression, and organizational outcomes of service delivery. LE role clarity was particularly important in organizational contexts where social integration of LE roles was low. Our study puts lived experience at the forefront of HRM scholarly debate, highlighting how employing LE roles can achieve better performance, diversity and inclusion outcomes especially for those with mental health challenges, and support the development of more healthy and inclusive organizations.
Factors influence user’s intention to continue use of e-banking during COVID-19 pandemic: the nexus between self-determination and expectation confirmation model

PurposeInternet banking services are proven to be much advantageous and convenient during COVID-19 pandemic. However, vibrant networking designs and dynamic changes in software development have made these services bit complex. Thus, the current study seeks to investigate Internet banking user continuance intention with factors underpinning self-determination theory (SDT) and expectation confirmation model (ECM) theory. The moderating role of image is studied between user intention to continue use of Internet banking and intention to recommend Internet banking service in social networks during COVID-19 pandemic.Design/methodology/approachThe quantitative research approach is applied and data collected through a research survey. For inferential analysis, 360 responses were collected from active Internet banking users. The integrated information system model was empirically tested using structural equation modeling (SEM) approach.FindingsFindings indicate that integrated IS research model has substantial explanatory power, i.e. 57.8% to predict continuance intention of Internet banking users. Within integrated research model, intrinsic regulation was found the most influential factor in order to determine Internet banking user continuance intention. Beside two theories integration, this study confirmed that the relationship between user continuance intention and intention to recommend Internet banking is moderated by image.Practical implicationsThe fundamental contribution of this study is the integration of technological and motivational factors in Internet banking user continuance intention context. Theoretically, integration of both theories ECM and SDT in technology continuance intention context will enrich the emerging e-commerce literature. Concerning with managerial implications, intrinsic regulation was identified as an important factor among other factors. Therefore, managers and software developers need to understand user’s intrinsic motivational factors in order to boost continuance intention of Internet banking users. It is also suggested that managers and marketing personnel should pay special attention to create a positive image of Internet banking services among Internet banking users.Originality/valueWithin information system literature the concept of user continuance intention has yet to be examined especially in Internet banking context. Thus, current research fills research gap and proposes an integrated technology motivational framework that combines motivational factors and technology factors altogether to investigate Internet banking user continuance behavior.
Older Adults’ Relocation Transitions: Relation of Place, Leisure and Identity

ABSTRACT Research and theory suggest that leisure, sense of home, and identity are all implicated in older adults moving to new residences. An integrative review was conducted to provide a more in-depth understanding of how these concepts inter-relate and shape older adults’ moving to new homes. Seventeen studies were included, and thematic analysis showed that older adults continued, adapted, and changed their leisure activities and used leisure to develop a sense of home and maintain identity. This review can inform practice and policy initiatives, and further research could enhance understanding of leisure’s role in older adults’ transition to new homes.
Toward Improving the Reliability of Discrete Movement Recognition of sEMG Signals

Currently, the classification accuracy of surface electromyography (sEMG) signals is high in literature, but the conventional recognition system may classify untrained movements or the trained movements of low reliability to one of its target classes by mistake. If such a system is used for prosthetic control, sometimes it may cause a disaster. A two-layer classifier that fuses the Gaussian mixture model (GMM) and k-nearest neighbor (kNN) in a sequential structure is proposed in this study. The proposed algorithm can reject the trained movements with low reliability and is efficient in rejecting the untrained movements, thus enhancing the reliability of the myoelectric control system. The results show that the proposed algorithm can produce 95.7% active accuracy in recognizing 12 trained movements and a 30.3% error rate for rejecting 12 untrained movements. When the movement number is six, the active accuracy for trained movements can reach 99.2%, and the error rate of untrained movement is only 17.4%, which is much better than previous studies. Therefore, the proposed classifier can accurately recognize the trained movements and reject untrained movement patterns effectively.
Investigating Tropical Versus Extratropical Influences on the Southern Hemisphere Tropical Edge in the Unified Model

Since the late 1970s, observations have shown a widening of the tropical Hadley cell (HC) circulation. State‐of‐the‐art climate models reproduce the general trend along with a projected continuous expansion. Discrepancies in expansion rates of observation‐ and model‐based studies have been attributed to differences in applied methods, natural variability and model shortcomings. Furthermore, the driving influence of tropical or extratropical processes on these changes is not well understood. All of this highlights the dynamical mechanisms and the region of origin controlling the tropical width are still insufficiently understood. Here we examine the influence of systematic model biases of the atmosphere‐only Unified Model (UM) onto the simulation of the Southern Hemisphere (SH) tropical edge. We utilize nudged experiments with prescribed sea surface temperatures, where potential temperature and horizontal winds are relaxed back to ERA‐Interim reanalysis for a 20‐year period in selected regions. Correcting model biases in the tropics and extratropics separately allows us to dissect the dominant remote impacts of present model errors onto the SH tropical edge simulation. The experiments are applied to established tropical width metrics ranging from near‐surface to upper‐level metrics capturing the poleward flank of the HC. We find both regions work remotely to reduce errors in the UM fields and location of the tropical edge. Surprisingly, correcting the extratropical biases, south of 45°S, more consistently improves the tropical width across the metrics and seasons than nudging the tropics (10°N–10°S). These findings demonstrate the substantial role of extratropical influences in locating the SH tropical edge.
Revisiting the Inscrutable Granular Cell Tumors in the Breast and Beyond: An Institutional Experience

Background: Granular cell tumors (GrCTs) are rare neoplasms derived from Schwann cells and can affect any part of the body. They are histologically categorized into benign (most common), atypical, or malignant (<2%) subtypes.Methods: A retrospective review of pathology-proven GrCTs at a tertiary hospital was done from 4/1/2014 to 3/31/2021. The patient age, gender, location of the tumor, and imaging findings were reviewed.Results: A total of 18 patients with GrCTs were found over a period of 7 years. The sites of involvement ranged from the tongue to the heel. The most common site of occurrence was the esophagus. There were 2 cases of recurrences and 2 cases of multicentric GrCTs. In our study, we did not have atypical or malignant GrCTs. Conclusion: Granular cell tumors are uncommon and primarily published as case reports and case series. Our seven-year review provides a comprehensive synopsis of this tumor in the breast and rest of the body. Their clinical and imaging features are non-characteristic, but histopathologic features with immunohistochemistry are diagnostic. Complete surgical excision with negative margins is the accepted standard of care. A global overview of this tumor will allow physicians to provide their patients with a better understanding of their diagnosis and prognosis.
Have disruptive innovations arrived at the gates of academia

Disruptive technologies in education and particularly Massive Open Online Courses (MOOCs) continue to be one of the polarising and most controvertible topics in postsecondary education, as they have yet to deliver on their promises. Existing academic literature on MOOCs, the main example of disruptive technology of this thesis, is primarily concerned with student participation, persistence, completion rates and learning in MOOC platforms. There seems however to be very limited scholarly research in the UK investigating the democratising effects and impact of disruptive technologies in Higher Education, particularly the extent to which MOOCs might unlock the gates to accessibility and their impact on universities, teaching and academics, through the lens of critical theory. It is however crucial to evaluate their impact (s) to inform policy decision-making on technology enhanced-learning implementation at tertiary institutions and design of curricula. The Main Research Question (MRQ) and sub-question designed for this study were addressed by conducting eighteen semi-structured interviews (Skype and face-to-face) with participants (academic and senior administrators) from nine countries and nine institutions. The research methods used were primarily qualitative. This thesis contributes to the field of technology-enhanced learning by addressing the current pedagogical limitations of the MOOC format which seem to be the critical impediments that prevent MOOCs, as they are currently designed, from genuinely democratising Higher Education to those who most need it in developed and developing countries. My main original contribution to knowledge is an integrated and adaptive model with critical success factors that would influence the MOOC model’s effectiveness, which, to the best of the author’s knowledge, is unique in the published literature. The findings of this study indicate that MOOCs have democratised access to Higher Education to a certain degree but they are not considered comparable to an on-campus experience and not suitable, in their current form and design, to the needs of the underrepresented in higher education, in developed and developing countries. The findings also indicate that MOOCs are challenging the current economic, business and pedagogical models and delivery mechanisms of traditional Higher Education and these might have an important effect on the academic role and identity. Furthermore, this investigation finds that MOOCs have aroused institutions and academics’ interest in and exploration of technology-enhanced learning, particularly blended learning approaches. Finally, the findings of this study indicate that MOOCs have impelled institutions and academics to rethink the design of more engaging courses and programmes and refocus on student learning to improve online and face-to-face teaching and this added pressure might have created a schism between the educational conservatives and the advocates of reform.
Implementing wildlife fences along highways at the appropriate spatial scale: A case study of reducing road mortality of Florida Key deer

Florida Key deer mortality data (1966–2017) showed that about 75% of all reported deer mortalities were related to collisions with vehicles. In 2001–2002, the eastern section of US Hwy 1 on Big Pine Key (Florida, USA) was mitigated with a wildlife fence, 2 underpasses, and 4 deer guards. After mitigation, the number of reported Key deer road mortalities reduced substantially in the mitigated section, but this was negated by an increase in collisions along the unmitigated section of US Hwy 1 on Big Pine Key, both in absolute numbers and expressed as a percentage of the total deer population size. The data also showed that the increase in Key deer collisions along the unmitigated highway section on the island could not be explained through an increase in Key deer population size, or by a potential increase in traffic volume. The overall Key deer road mortality along US Hwy 1 was not reduced but was moved from the mitigated section to the nearby unmitigated section. Thus, there was no net benefit of the fence in reducing collisions. After mitigation, a significant hotspot of Key deer-vehicle collisions appeared at the western fence-end, and additional hotspots occurred further west along the unmitigated highway. Exploratory spatial analyses led us to reject the unmitigated highway section on Big Pine Key as a suitable control for a Before-After-Control-Impact (BACI) analysis into the effectiveness of the mitigation measures in reducing deer-vehicle collisions. Instead, we selected highway sections west and east of Big Pine Key as a control. The BACI analysis showed that the wildlife fence and associated mitigation measures were highly effective (95%) in reducing deer-vehicle collisions along the mitigated highway section. Nonetheless, in order to reduce the overall number of deer-vehicle collisions along US Hwy 1, the entire highway section on Big Pine Key would need to be mitigated. However, further mitigation is complicated because of the many buildings and access roads for businesses and residences. This case study illustrates that while fences and associated measures can be very effective in reducing collisions, wildlife fences that are too short may result in an increase in collisions in nearby unmitigated road sections, especially near fence-ends. Therefore it is important to carefully consider the appropriate spatial scale over which highway mitigation measures are implemented and evaluated.
Use of Butaphosphan with Cyanocobalamin in High Producing Cows and Associations with Milk Yield and Dry Matter Intake

This study aimed to verify the effect of butaphosphan combined with cyanocobalamin (B+C) on dry matter intake (DMI) and milk yield in high producing dairy cows. Eighteen multiparous Holstein cows managed in a compost barn system were enrolled on a calving date and remained under observation until 28 days in milk (DIM). The B+C group administered at 2500 mg of butaphosphan and 1.25 mg of cyanocobalamin (25 mL/cow/day, n = 9), or the control group (NaCl 0.9% administered at 25 mL/cow/day, n = 9,) receiving injections at calving, and at day 3 and 7 post-partum. The DMI, feed efficiency, and DMI/% body weight were evaluated until 21 DIM and the milk yield, rumination, activity, and lying time until 28 DIM. Various metabolites were evaluated at 0, 3, 7, 14, 21, and 28 DIM. DMI did not change with treatment. Milk yield was more significant in the B+C group than in the control group, with an increase of 3.66 kg/milk/d. The maintenance of DMI and the greater milk yield in the B+C group may suggest that the use of B+C can improve feed efficiency. No treatment effect was observed for concentrations of serum glucose, NEFA, BHB, and acetone, however, albumin was higher in B+C than in control. No effect was observed on milk composition. Our results suggest that B+C improves milk yield and feed efficiency by modulating the DMI.
Missing and murdered indigenous women and girls in Canada: a new population affinity assessment technique to aid in identification using 3D technology

Abstract As of 2015, 204 cases of missing and murdered Indigenous women and girls (MMIWG) remained unsolved in Canada, making it a major concern for Canadian Indigenous communities, who are still pressing for the resolution of these cases. In forensic anthropology, the assessment of population affinity can be useful to help identify victims. Population affinity, previously referred to as ancestry, is evaluated based on morphological analyses, which examine the size and shape of skeletal features, and metric analyses, which utilise skeletal measurements. However, morphological analyses strongly depend on an anthropologist’s experience with human variation, which makes the analyses particularly challenging to reproduce and standardise. The purpose of this study is to improve the rigour of morphological analyses by using 3D technology to quantify relevant cranial nonmetric population affinity traits. As there is currently little morphological data available for the Canadian Indigenous population, this research aims to develop a new technique that could aid in the identification of MMIWG. The study comprised a total of 87 adult female crania, including 24 of Canadian Inuit origin, 50 of European descent and 13 of African descent. The samples were imaged using photogrammetry, then analysed using a 3D shape analysis in 3DS Max. Results show that this method is satisfactory in correctly evaluating population affinity with an accuracy of 87.36% (jackknifed: 80.46%) and an average repeatability of 97%. Unfortunately, the small Canadian Indigenous sample size impacted the applicability of the results and further research will be required before the technique can be used to aid in the identification of MMIWG in Canada.
Rickettsial Pathogen Perturbs Tick Circadian Gene to Infect the Vertebrate Host

Ixodes scapularis is a medically important tick that transmits several microbes to humans, including rickettsial pathogen Anaplasma phagocytophilum. In nature, these ticks encounter several abiotic factors including changes in temperature, humidity, and light. Many organisms use endogenously generated circadian pathways to encounter abiotic factors. In this study, we provide evidence for the first time to show that A. phagocytophilum modulates the arthropod circadian gene for its transmission to the vertebrate host. We noted a circadian oscillation in the expression of arthropod clock, bmal1, period and timeless genes when ticks or tick cells were exposed to alternate 12 h light: 12 h dark conditions. Moreover, A. phagocytophilum significantly modulates the oscillation pattern of expression of these genes. In addition, increased levels of clock and bmal1 and decreased expression of Toll and JAK/STAT pathway immune genes such as pelle and jak, respectively, were noted during A. phagocytophilum transmission from ticks to the vertebrate host. RNAi-mediated knockdown of clock gene expression in ticks resulted in the reduced expression of jak and pelle that increased bacterial transmission from ticks to the murine host. Furthermore, clock-deficient ticks fed late and had less engorgement weights. These results indicate an important role for circadian modulation of tick gene expression that is critical for arthropod blood feeding and transmission of pathogens from vector to the vertebrate host.
