Uncertainty and Congestion Elimination in 4G Network Call Admission Control using Interval Type-2 Intuitionistic Fuzzy Logic
The management and control of the global growth and complex nature of wireless Fourth Generation (4G) Networks elicits the need for Call Admission Control (CAC). However, CAC faces the challenge of network congestion, thereby deteriorating the network Quality of Service (QoS) due to inherent imprecision and uncertainties in the QoS data which leads to difficulties in measuring some objective and constraints of QoS using crisp values. Previous researches have shown the strength of Interval Type-2 Fuzzy Logic System (IT2FLS) in coping adequately with linguistic uncertainties. Intuitionistic fuzzy sets (IFSs) have indicated their ability to further reduce uncertainty by handling conflicting evaluation involving membership (M), nonmembership (NM) and hesitation. This paper applies the Interval Type-2 Intuitionistic Fuzzy Logic System (IT2IFLS) in solving CAC problem in order to achieve a better QoS in 4G Networks
Perceptions of the Impact of Positive Action in EU and non-EU Countries
yesAbstract: Around the world, inequalities exist around boundaries of race, social class, gender, disability,
religious beliefs and sexual orientation, often resulting from past and current discriminatory
practices. Governments have taken certain measures, including enacting policies such as positive action,
to remedy such discrimination. This paper provides a comparative analysis of perceptions of the impact
of positive action in seven EU and three non-EU countries. The study adopted participatory methods
including consensus workshops, interviews and policy analysis to obtain data from designers of positive
action. Findings are discussed, conclusions drawn and wide-ranging recommendations are made at
the EC, individual countries and organisational levels
Positive Action Measures Across Different Equality Grounds, Organisations and Sectors in European and Non-european Countries
yesAbstract: This article is based on a large-scale European Commission project on international perspectives
on positive action measures. The paper presents an analysis of the perceptions of positive
action held by respondents from all the countries participating in an international survey, focussing
specifically upon differences across equality grounds, sector and organisation type. This paper will
also provide examples of positive action being applied in European and non-European countries that
participated in the study. The study adopted extensive literate and online survey to obtain data from
designers of positive action. Findings are discussed, conclusions drawn and wide-ranging recommendations
are made at the European Commission, individual countries and organisational levels
Methodological Challenges of Researching Positive Action Measures
This paper highlights some ofthe methodological challenges which have arisen in collecting
data for an international study on positive action measures. It will describe strategies employed to
encourage participation in the study from as wide a range of organisations and individuals using a
mixed method approach. The paper will also discuss the methodological and sensitive issues related
to this type of research in organisations and strategies adopted by the research team to ameliorate
any problems that have arisen whilst maintaining trustworthiness and rigour in the study

Characteristics associated with subjective and objective measures of treatment success in women undergoing percutaneous tibial nerve stimulation vs sham for accidental bowel leakage.
INTRODUCTION AND HYPOTHESIS: In randomized trials both percutaneous tibial nerve stimulation (PTNS) and sham result in clinically significant improvements in accidental bowel leakage (ABL). We aimed to identify subgroups who may preferentially benefit from PTNS in women enrolled in a multicenter randomized trial. METHODS: This planned secondary analysis explored factors associated with success for PTNS vs sham using various definitions: treatment responder using three cutoff points for St. Marks score (≥3-, ≥4-, and ≥5-point reduction); Patient Global Impression of Improvement (PGI-I) of ≥ much better; and ≥50% reduction in fecal incontinence episodes (FIEs). Backward logistic regression models were generated using elements with significance of p<0.2 for each definition and interaction terms assessed differential effects of PTNS vs sham. RESULTS: Of 166 women randomized, 160 provided data for at least one success definition. Overall, success rates were 65% (102 out of 158), 57% (90 out of 158), and 46% (73 out of 158) for ≥3-, ≥4-, and ≥5-point St Marks reduction respectively; 43% (68 out of 157) for PGI-I; and 48% (70 out of 145) for ≥50% FIEs. Of those providing data for all definitions of success, 77% (109 out of 142) met one success criterion, 43% (61 out of 142) two, and 29% (41 out of 142) all three success criteria. No reliable or consistent factors were associated with improved outcomes with PTNS over sham regardless of definition. CONCLUSIONS: Despite exploring diverse success outcomes, no subgroups of women with ABL differentially responded to PTNS over sham. Success results varied widely across subjective and objective definitions. Further investigation of ABL treatment success definitions that consistently and accurately capture patient symptom burden and improvement are needed
How Hypertension Rates and HIV Treatment Outcomes Compare between Older Females and Males Enrolled in an HIV Treatment Program in Southern Nigeria: A Retrospective Analysis
Studies show that treatment outcomes may vary among persons living with HIV. To fast-track the attainment of epidemic control across gender and age groups, the Accelerating Control of the HIV Epidemic (ACE-5) Project implemented in Akwa Ibom and Cross Rivers States, Nigeria, examined the hypertension rates and treatment outcomes of older adults living with HIV. The demographic and treatment characteristics of males and females ≥ 50 years living with HIV, who initiated antiretroviral therapy (ART) as of September 2021, were abstracted from medical records across 154 health facilities and community sites in Akwa Ibom and Cross River states, Nigeria. We compared these characteristics by sex using the chi-square test. The log-rank test was used to compare differences in their retention (i.e., being on treatment) and viral suppression (VS) rates [3, with more males having lower baseline CD4 than females [13.4% of males vs. 10.2% of females, p-value = 0.004]. In total, 59.9% received treatment at out-of-facility locations, with more males receiving treatment in this setting than females [65.7% vs. 54.8% p-value p-value p = 0.901; VS: p = 0.056]. VS was slightly but not significantly higher among females than males (98.8% versus 99.2%; Aor = 0.79, 95%CI = 0.58–1.10, p = 0.17). Although older males and females living with HIV had similar treatment outcomes, hypertension screening was suboptimal and could impact long-term morbidity and mortality. Our study emphasizes the need to integrate noncommunicable disease screening and the management of hypertension in the care of older persons living with HIV
A Multi-Faceted Approach to Tuberculosis Active Case Finding among Remote Riverine Communities in Southern Nigeria
Nigeria accounts for 11% of the worldwide gap between estimated and reported individuals with tuberculosis (TB). Hard-to-reach communities on the Southern Nigeria coast experience many difficulties accessing TB services. We implemented an active case finding (ACF) intervention in Akwa Ibom and Cross River states utilizing three approaches: house-to-house/tent-to-tent screening, community outreach and contact investigation. To evaluate the impact, we compared TB notifications in intervention areas to baseline and control population notifications, as well as to expected notifications based on historical trends. We also gathered field notes from discussions with community volunteers who provided insights on their perspectives of the intervention. A total of 509,768 individuals were screened of which 12,247 (2.4%) had TB symptoms and 11,824 (96.5%) were tested. In total, 1015 (8.6%) of those identified as presumptive had confirmed TB—98.2% initiated treatment. Following implementation, TB notifications in intervention areas increased by 112.9% compared to baseline and increased by 138.3% when compared to expected notifications based on historical trends. In contrast, control population notifications increased by 101% and 49.1%, respectively. Community volunteers indicated a preference for community outreach activities. Multi-faceted, community-based interventions in Nigeria’s coastal areas successfully increase TB detection for communities with poor access to health services
