Shifted Rayleigh filter: a novel estimation filtering algorithm for pervasive underwater passive target tracking for computation in 3D by bearing and elevation measurements
Authors: Kavitha Lakshmi M. , Koteswara Rao S. , Subrahmanyam K. 
Published: November 2021

Purpose
Marine exploration is becoming an important element of pervasive computing underwater target tracking. Many pervasive techniques are found in current literature, but only scant research has been conducted on their effectiveness in target tracking.

Design/methodology/approach
This research paper, introduces a Shifted Rayleigh Filter (SHRF) for three-dimensional (3 D) underwater target tracking. A comparison is drawn between the SHRF and previously proven method Unscented Kalman Filter (UKF).

Findings
SHRF is especially suitable for long-range scenarios to track a target with less solution convergence compared to UKF. In this analysis, the problem of determining the target location and speed from noise corrupted measurements of bearing, elevation by a single moving target is considered. SHRF is generated and its performance is evaluated for the target motion analysis approach.

Originality/value
The proposed filter performs better than UKF, especially for long-range scenarios. Experimental results from Monte Carlo are provided using MATLAB and the enhancements achieved by the SHRF techniques are evident.
Keeping a distance but heading in the same direction: formal rules on unemployment benefit sanctions and social assistance benefit sanctions in Poland, 1989–2014
Authors: Pieliński Bartosz , Mering Tomasz , Szarfenberg Ryszard 
Published: November 2021

PurposeThis paper aims to examine the development of welfare conditionality and especially benefit sanctions in Central and Eastern Europe (the CEE) and to develop a methodology by implementing Institutional Grammar (IG) for studying rules on benefit sanctions relying only on legal text.Design/methodology/approachIG was used as a tool for analyzing legal regulations on benefit sanctions. It was incorporated into a social rights framework that provided a theoretical background for the study.FindingsThe paper shows the dynamic development of rules on benefit sanctions in Poland in social assistance and unemployment services. Both the harshness and strictness of these rules have increased. Simultaneously, the rules of benefit sanctions in social assistance remain more liberal than those associated with unemployment services.Originality/valueThe study presents the first comprehensive and concise overview of benefit sanctions development in the CEE and the first long-term comparison of these types of sanctions in two safety net systems operating in one country. The study also used IG for the first time in social policy research.

Published: November 2021

PurposeThis study analyses the sequence of actions carried out by successful enterprises in the agricultural sector and aims to understand the logic followed with such actions and the differences related to the types of families that develop them.Design/methodology/approachThrough a multiple case study approach, the business and family trajectories of 14 successful agricultural enterprises in Mexico were analysed. The actions carried out by enterprises are conceptualized as strategic movements and are classified into seven categories: (1) growth and intensification, (2) reconversion, (3) diversification, (4) integration, (5) differentiation, (6) outsourcing and (7) digitization. Depending on their relationship with agriculture, entrepreneurial families are classified into three categories: (1) continuing families, (2) returning families and (3) incoming families.FindingsThe entrepreneurship logic follows three stages: evaluation, expansion and consolidation, through which different activities are tested, then the one that produces the best results is expanded and adopted as the main activity, and finally the expansion of the main activity and its evaluation are combined by comparing and complementing it with other agricultural activities. The difference is that continuing families adhere more to the traditional productivist model based on growth in scale and improved productivity of primary production. On the other hand, actions that imply a distinction in the quality of production such as integration and differentiation and that require links with other organizations such as outsourcing are more frequently carried out by returning and incoming families.Research limitations/implicationsThe findings obtained through case studies cannot be statistically generalized to a specific population, however, our perspective can be transferred to other cases to obtain analogous findings.Originality/valueThe study is a unique piece in terms of the analysis of how families with different degrees of proximity to agriculture develop successful enterprises.
Impact of company and country antecedents on B2B buyer perceived supplier performance
Authors: Uddin Jashim , Elliott Gregory , Parvin Shehely 
Published: November 2021

PurposeTo date, country-of-origin research has commonly explored structural relationships among country image (CI) constructs, together with attitudinal constructs, using a variety of halo, summary construct and flexible models, drawing on consumer samples. There has been no previous attempt to examine or synthesize these three models with respect to business-to-business (B2B) buying behavior. To fill this gap, this study reconceptualized these three models with B2B constructs using multi-cue settings and tested on B2B samples. This study aims to examine and estimate the relative impact of company- and country-specific images on B2B buyers’ evaluations of suppliers, and the direction of structural relationships with mediation among the constructs.Design/methodology/approachData collection was administered through a web-based structured questionnaire. The final sample consisted of 276 purchasing managers. Structural equation modeling was used to test the study’s hypotheses.FindingsCompany image is significantly influenced by product country image (PCI) but not by overall CI. The existence of a significant relationship between PCI and perceived supplier performance in a multi-cue setting is an important new finding. In addition, company image significantly influences supplier performance and mediates the relationship between PCI and supplier performance. Among the three models that test structural relationships among CI and other constructs, the reconceptualized halo model fits the data best.Practical implicationsThe study results revealed the contribution of company and country-related facets on B2B buyers’ perceptions of supplier performance while purchasing intermediate goods internationally. The significance of PCI on supplier performance emphasizes the strength of the industry sector within a country that may enable an industry to build a product-specific CI in international marketing.Originality/valueThis study advances the country-of-origin issue and debate concerning the strength of the country influence in the academic literature by addressing B2B buyers’ international purchasing behavior of intermediate goods. Additionally, the examination of multiple country facets, multi-cue settings and the CI influence structure in a single study, from a B2B perspective, offers a novel dimension to CI studies.
The digitalization-reputation link: a multiple case-study on Italian banking groups
Authors: Bernini Francesca , Ferretti Paola , Angelini Antonella 
Published: November 2021

PurposeThis paper aims to focus on the relation between digital transformation and banks’ reputation, as examined through the information disclosed by the five largest Italian banking groups’ efforts to extend and enhance their digital resources. Considering digitalization as a key strategy for managing reputation, which, in turn, can leverage financial and value performance management, the paper investigates whether and how digital activities might affect banks’ reputation. Therefore, this paper proposes the relationship between digitalization and reputation as a lever for performance management and for increasing efficiency.Design/methodology/approachThe authors use content analysis to generate a digital disclosure index, categorizing activities human, structural and relational. For banks’ reputations, the proxies are a measure of corporate reputation and a reputational risk index. Methodologically the study used multiple case studies, considered as particularly suitable to gain an in-depth understanding of the topic in the case of the five banks. A collection of secondary data and semi-structured interviews are included.FindingsOverall, the digitalization-reputation link shows that banks’ reputation is variously affected, not only by exposure to risk (including reputational risk) but also by strategic issues such as digitalization and the effectiveness of the corresponding communication. Consequently, banks should view digitalization as a key driver to be considered not in a stand-alone perspective, but in a combined approach.Research limitations/implicationsContinued research should include the Covid-19 implications. Additionally, it would be important to compare a larger number of banks, with different characteristics, also including variables indicating the corporate governance mechanisms.Practical implicationsThe analysis contributes to fostering scholars’ and practitioners’ management of the digital transformation challenge that is a current key-factor, capable of increasing banks’ value. It considers not only the drivers directly affecting monetary value but also the institutions’ social and relational value, as well as their reputation.Originality/valueThis paper extends prior research on the digitalization-reputation relation by investigating digital transformation through disclosure of activities in this area within the Italian banking sector. It allows to leverage the key-factors that can contribute to increasing banks’ value, considering not only the drivers directly affecting monetary value but also the institutions’ social and relational value, as well as their reputation.

Published: November 2021

Purpose
This paper aims to investigate the root causes of and implement the improvements for the inter layer dielectric (ILD) crack for LQFP C90FG (CMOS90 Floating Gate) wafer technology devices in copper wire bonding process.

Design/methodology/approach
Failure analysis was conducted including cratering, scanning electron microscopy inspection and focus ion beam cross-section analysis, which showed ILD crack. Root cause investigation of ILD crack rate sudden jumping was carried out with cause-and-effect analysis, which revealed the root cause is shallower lead frame down-set. ILD crack mechanism deep-dive on ILD crack due to shallower lead frame down-set, which revealed the mechanism is lead frame flag floating on heat insert. Further investigation and energy dispersive X-ray analysis found the Cu particles on heat insert is another factor that can result in lead frame flag floating.

Findings
Lead frame flag floating on heat insert caused by shallower lead frame down-set or foreign matter on heat insert is a critical factor of ILD crack that has never been revealed before. Weak wafer structure strength caused by thinner wafer passivation1 thickness and sharp corner at Metal Trench (compared with the benchmarking fab) are other factors that can impact ILD crack.

Originality/value
For ILD crack improvement in copper wire bonding, besides the obvious factors such as wafer structure and wire bonding parameters, also should take other factors into consideration including lead frame flag floating on heat insert and heat insert maintenance.
Subtle workplace discrimination inhibiting workers with intellectual disability from thriving at the workplace
Authors: Cavanagh Jillian , Meacham Hannah , Pariona-Cabrera Patricia , Bartram Timothy 
Published: November 2021

PurposeThe purpose of the article is to examine the experiences of workers with intellectual disability (WWID) and subtle discriminatory practices that hold these workers back from thriving at the workplace.Design/methodology/approachThe research design employs the Shore et al. (2011) framework of inclusion supported by optimal distinctiveness theory (ODT) (Brewer, 1991). These theoretical frames are used to examine the potential for WWID to become members of a work group and experience the opportunity to develop their unique selves, negotiate and thrive through their work for purposeful career outcomes. A qualitative case study approach was adopted through interviews and focus groups with a total of 91 participants: 41 WWID, 5 human resource (HR) managers, 5 duty/department managers (DMs), 24 colleagues and 16 supervisors.FindingsThe authors found that enhancing inclusion is underpinned by the positive impact of human resource management (HRM) practices and line management support for WWID feelings of belongingness and uniqueness that enable them to thrive through their work activities. The authors demonstrate that WWID need manager support and positive social interactions to increase their learning and vitality for work to embrace opportunities for growth. However, when WWID do not have these conditions, there are fewer opportunities for them to thrive at the workplace.Practical implicationsThere is a need for formal HRM and management support and inclusive organisational interventions to mitigate discriminatory practices and better support WWID at work. There is an opportunity for HRM to design training and development around belongingness and uniqueness for this cohort of workers to maximise WWID opportunities to thrive through their work.Originality/valueThis study examines a cohort of WWID who are often forgotten and subtly discriminated against more so than other minority or vulnerable cohorts in the workplace, especially in terms of their development and reaching their full potential at work, which has an impact on their ability to thrive through their work. The paper makes an innovative contribution to the HRM literature through unpacking the processes through which Shore et al.'s (2011) conceptualisation of belongingness and uniqueness contributes to thriving for a marginalised and often overlooked cohort of workers.
Synthesis of nano-porous ZNO as pigment for white silicone thermal control coating and investigation of structure, optical and thermal properties
Authors: Heydari Vahid , Bahreini Zaker , Abdouss Majid 
Published: November 2021

Purpose
The harsh environment of space, especially radiation of direct solar rays, can potentially raise the temperature of the spacecraft to harmful levels. Thermal control coatings (TCCs) fix the thermal condition of the spacecraft acceptable for its components. This is possible by diffusely reflecting all effective ultraviolet (UV), visible (VIS) and near infrared (IR) (NIR) wavelengths of solar radiation and emmition of IR energy. The most commonly used TCCs have used ZnO as a pigment, but absorption of the UV light by ZnO pigment can change the ideal condition of these TCCs. The aim of his study is the using the porous ZnO particles as pigment to prevent the UV absorption.

Design/methodology/approach
To enhance the efficiency of these coatings, in the present study, nano-porous zinc oxide particles were synthesized and used as pigments for white TCCs.

Findings
The results revealed that the proposed TCC (TPZ), Thermal control coating with porous ZnO had better reflection (scattering) and emittance properties in comparison with the coating using ZnO as a pigment (TZ coating); so this coating had a solar absorptance value equal to 0.141, whereas this value for TZ was 0.150. Furthermore, TPZ showed higher thermal emittance (0.937) in comparison with TZ (0.9). These changes were because of the improvement in the refractive index, shape and surface area of the pigments. The general trend of the scattering coefficients for the prepared coating, as calculated from the Kubelka–Munk equation, showed that scattering was more efficient in the UV region, as compared with the TCC containing ZnO pigments.

Originality/value
This type of pigment for the first time is evaluated in TCCs.
Investigation of vibratory bed effect on abrasive drag finishing: a DEM study
Authors: Beigmoradi Sajjad , Vahdati Mehrdad 
Published: November 2021

Purpose
The purpose of this paper is to investigate the effect of a vibratory bed, as an assistant agent, on the improvement of the drag finishing process. The dynamics and kinematic of the process were surveyed in microscale for different frequencies and amplitudes and the results were compared to the basic process.

Design/methodology/approach
The discrete element tool was used to find out the effect of the vibratory bed on the drag finishing process. To this end, the Hertz-Mindlin model was used to investigate the contact of abrasive particles and workpiece. At the first stage, the numerical model was validated with the experimental results, and then the effect of different parameters on the finishing process was evaluated and compared with the basic case.

Findings
The chosen numerical model was in good agreement with the results measured in the previous literature. Moreover, the results show that not only vibrated bed enhances the contacts of abrasive particles to the workpiece, but it also increases the uniformity of the finished surface.

Originality/value
In comparison to the experiments, the discrete element technique consumes lower cost and time to estimate the optimum conditions of the finishing process, as well as it provides a good understanding of this phenomenon on the micro-scale.

Published: November 2021

AbstractBackgroundInternational Federation of Gynaecology and Obstetrics (FIGO) staging of carcinoma cervix, although essentially clinical, acknowledges the benefits of MRI. The impact of incorporating MRI in staging of cervical cancer and the discordance between clinical‐and MRI‐based FIGO staging is not well studied, especially in low‐ and middle‐income countries.AimWe aim to study the role and accuracy of MRI in staging carcinoma cervix, its correlation with clinical FIGO and histopathological staging with emphasis on how it can change treatment plan.MethodsRetrospective observational cohort study (n = 193) where MRI details of different staging parameters of the study subjects were compared with clinical FIGO staging and histopathology to assess correlation and agreement between them. Change of clinical FIGO stage and hence treatment plan brought about by incorporating MRI was assessed.ResultsMRI had a tumor detection rate of 94.3%, overall staging accuracy of 78.3% and very strong correlation with histopathology (Spearman's coefficient of rank correlation, r = 0.886). Clinical FIGO and MRI had agreement only in 52.8% cases (r = 0.61). Incorporating MRI changed the clinical stage in 47.2% patients and subsequently modified primary treatment plan in 23.3%.ConclusionMRI is highly accurate in evaluating carcinoma cervix and has good correlation with histopathology. Our data shows low agreement between MRI and clinical FIGO staging. Thus, incorporating MRI in FIGO staging has considerable impact in altering treatment decisions and should be offered to all patients for staging carcinoma cervix.

Published: November 2021

AimsSome population pharmacokinetic models have been developed using height to explain some of the interindividual variability in tobramycin pharmacokinetics in cystic fibrosis patients. However, their predictive performance when extrapolated to other clinical centres is unclear. Therefore, the aim of this study was to externally evaluate the predictability of tobramycin population pharmacokinetic models with an independent dataset and perform simulations using previously recommended height‐based dosing regimens.MethodsA literature search was conducted through the PubMed database to identify relevant population pharmacokinetic models. Tobramycin plasma concentration data from April 2014 to November 2019 were retrospectively collected from the Institut universitaire de cardiologie et de pneumologie de Québec, Canada. External evaluations were performed using NONMEM® v7.5 and RStudio® v1.3.1073. Monte Carlo simulations were performed to evaluate the probability of target attainment of Cmax/MIC ratios for several dosing regimens.ResultsThe validation dataset included 27 patients and 143 concentration samples. Three models were evaluated. Only the ones by Crass et al. and Alghanem et al. performed satisfactorily in terms of prediction‐based diagnostics with MDPE values of −3.4% and 29.3% and MDAPE values of 19.0 and 29.5%, respectively. In simulation‐based evaluations, both pcVPC and NPDE showed no evidence of model misspecification. Our simulations suggest that patients treated with a once‐daily dose of 3.4 mg/cm should produce peak and trough levels consistent with current guidelines.ConclusionOur results show that the models by Crass et al. and Alghanem et al. are appropriate for simulation‐based applications to aid individualized dosing in our population and that height‐based dosing regimens could be considered in cystic fibrosis patients.

Published: November 2021

AbstractIntroductionThe manifestation of bipolar disorder (BD) is hypothesized to be determined by clinical characteristics such as familial loading, childhood abuse, age at onset, illness duration, comorbid psychiatric disorders, addiction, treatment resistance, and premorbid cognitive functioning. Which of these are associated with a more severe course and worse outcome is currently unknown. Our objective is to find a combination of clinical characteristics associated with advancement to subsequent stages in two clinical staging models for BD.MethodsUsing cross‐sectional data from the Dutch Bipolar Cohort, staging was applied to determine the progression of bipolar‐I‐disorder (BD‐I; N = 1396). Model A is primarily defined by recurrence of mood episodes, ranging from prodromal to chronicity. Model B is defined by level of inter‐episodic functioning, ranging from prodromal to inability to function autonomously. For both models, ordinal logistic regression was conducted to test which clinical characteristics are associated with subsequent stages.ResultsFor model A, familial loading, childhood abuse, earlier onset, longer illness duration, psychiatric comorbidity, and treatment resistance were all predictors for a higher stage in contrast to addiction and cognitive functioning. For model B, childhood abuse, psychiatric comorbidity, cognitive functioning, and treatment resistance were predictors for a more severe stage, whereas age at onset, illness duration, and addiction were not.Discussion/conclusionsDifferences in clinical characteristics across stages support the construct validity of both staging models. Characteristics associated with a higher stage largely overlapped across both models. This study is a first step toward determining different clinical profiles, with a corresponding course and outcome.
