Gentrification and Environmental Justice in Nigerian Cities
Gentrification is a process of urban revitalization by which the original inhabitants of an area are displaced, owing to the purchase and upgrading of their deteriorated properties by the middle or high income households. An aspect of gentrification that is of particular interest to Nigerians is the issue of displacement, with its attendant socio-economic alienation of the poor from the city, which has evoked some environmental justice concerns. Focusing on the city of Aba, this study examined gentrification and the environmental justice question in Nigerian cities. The study adopted survey research design, making use of qualitative and quantitative methods to analyse gentrification. Cluster and simple random sampling techniques were used to select 158 displaced household heads of gentrified buildings across the various neighbourhoods in Aba, who were surveyed. Data collected were analyzed with appropriate parametric tests using SPSS. Findings show that about 698 households are displaced in the city every year due to gentrification, with an annual displacement rate of 7.5%. This gentrification induced displacements have been found to constitute significant environmental injustice to the low income city residents as it leads to their dislocation from kin, and communal heritages; forces them to move into substandard housing at the urban fringes; and constrains some to relocate to the rural areas, limiting their abilities to cope with life’s challenges. The study therefore recommends among other things, that the Town Planning Authorities should create a platform to educate owners of rundown properties to adopt the model of market-led gentrification as presently practiced in Lagos city
Mindfulness-based interventions for psychological wellbeing and quality of life in men with prostate cancer: a systematic review and meta-analysis
Effect of Plant Spacing on the Growth and Yield of Forage Plant, Maize, Intercropped with Cowpea (\u3cem\u3eVigna unguiculata\u3c/em\u3e sub spp. \u3cem\u3esesquipedalis\u3c/em\u3e)
Feed constraint is the most important impediment to improved livestock production in the Sub-Saharan African (SSA) countries (Agyemang 2003), as a result of seasonal shortages in the quantity and quality of forage from natural pastures that supply most of the feed for animals due to the prolonged annual dry season. Appropriate technologies to improve the performance of the local animal breeds and feed resources under the traditional system are generally lacking. Maize forms a major part of the cereal crops consumed by man and the residues serve as a source of fodder for livestock (Asawalam and Adesiyan 2001). Demand for maize has led farmers to reduce planting spacing. When crops are grown sole, spacing and planting pattern differ from when intercropped. Maize is known to be a very heavy soil nutrient utiliser and usually produces low yield in situations of low soil fertility and poor agronomic practices. Intercropping maize with legumes has shown prospects for improving maize crop yield and this would result in a reduction in the use of high cost synthetic fertilizers. The cowpea is an example of such legume and little work has been done on plant spacing for this crop in an intercropping system with maize. Plant spacing is an important agronomic attribute as it has effects on light interception which is the energy manufacturing medium of green parts of the plant (Ibeawuchi, et al. 2008)
Physiotherapists’ role during hospital-to-home transition for older adults with hip fracture and mobility limitation: a research protocol
Musculoskeletal imaging authority, levels of training, attitude, competence, and utilisation among clinical physiotherapists in Nigeria: a cross-sectional survey
BACKGROUND: Direct-access physiotherapy practice has led to a global review of the use of differential-diagnostic modalities such as musculoskeletal imaging (MI) in physiotherapy. OBJECTIVE: To explore the MI authority, levels of training, attitude, utilisation, and competence among clinical physiotherapists in Nigeria. METHODS: This national cross-sectional study analysed a voluntary response sample of 400 Nigerian physiotherapists that completed the online version of the Physiotherapist’s Musculoskeletal Imaging Profiling Questionnaire (PMIPQ), using descriptive statistics, Spearman’s correlation, Mann-Whitney U, Kruskal-Wallis, and Friedman’s ANOVA tests. RESULTS: Of the 400 participants, 93.2% believed that physiotherapists should use MI in clinical practice. However, only 79.8% reported having MI authority in their practice settings. The participants’ median (interquartile range) levels of training =10 (24) and competence =16 (24) were moderate. Nonetheless, levels of training (χ2 [15] = 1285.899, p = 0.001), and competence (χ2 [15] = 1310.769, p < 0.001) differed across MI procedures. The level of training and competence in x-ray referral and utilisation was significantly higher than magnetic resonance imaging, computed tomography scan, ultrasonography, scintigraphy, and dual-energy x-ray absorptiometry, in that order (p < 0.05). There was a significant positive correlation between the levels of training and competence (rho =0.61, p < 0.001). The participants had a positive attitude =32 (32) and occasionally used MI in clinical practice =21 (28). CONCLUSION: Majority of the respondents believed they had MI authority although there was no explicit affirmation of MI authority in the Nigerian Physiotherapy Practice Act. Participants had a positive attitude towards MI. However, levels of MI training, competence, and utilisation were moderate. Our findings have legislative and curriculum implications
Model exploration and analysis for quantitative safety refinement in probabilistic B
The role played by counterexamples in standard system analysis is well known;
but less common is a notion of counterexample in probabilistic systems
refinement. In this paper we extend previous work using counterexamples to
inductive invariant properties of probabilistic systems, demonstrating how they
can be used to extend the technique of bounded model checking-style analysis
for the refinement of quantitative safety specifications in the probabilistic B
language. In particular, we show how the method can be adapted to cope with
refinements incorporating probabilistic loops. Finally, we demonstrate the
technique on pB models summarising a one-step refinement of a randomised
algorithm for finding the minimum cut of undirected graphs, and that for the
dependability analysis of a controller design.Comment: In Proceedings Refine 2011, arXiv:1106.348
A scoping review examining the integration of exercise services in clinical oncology settings
Background
Addressing questions surrounding the feasibility of embedding exercise service units in clinical oncology settings is imperative for developing a sustainable exercise-oncology clinical pathway. We examined available literature and offered practical recommendations to support evidence-based practice, policymaking, and further investigations.
Methods
Four thousand eight hundred sixty-three unique records identified in Embase, CINAHL, MEDLINE, Web of Science Core Collection, and ProQuest (Health and Medicine) were screened for studies that recruited cancer patients, assessed the co-location of exercise service and cancer treatment units, and reported findings on service implementation. Evidence from six studies providing data from over 30 programs was integrated using narrative synthesis.
Results
Service implementation was relatively modest across the included studies. Exercise services were delivered by physiotherapists, exercise physiologists, and kinesiologists and funded mainly through grants and private donations, with staff salaries accruing as the major expense. Service penetration, adoption, and acceptability were generally low. However, studies recorded high clinician/patient satisfaction. Major barriers to service integration were limited funding, lack of detailed implementation plan, and low organizational buy-in. Common reasons for non-utilization, missed sessions, and dropouts were lack of interest, unwellness, hospital readmission, disease progression, and adverse skeletal events.
Conclusion
Implementing exercise services in clinical oncology settings seems an effective approach for increasing access to exercise-based rehabilitation for individuals on cancer treatment. While this model appears feasible for patients/clinicians, efforts are required to optimize service integration both in the short and long term. Key priorities include seeking [local] actions to address issues relating to funding and organizational buy-in. Important considerations may include developing an implementation plan to guide the implementation process, expanding the patient core management team to include staff from the exercise rehabilitation unit, and exploring the role of patient feedback in increasing clinician participation (e.g., treating oncologists and nurses) in the referral process. Future research should consider effective strategies to promote patients’ sense of self-efficacy and behavioral control and, further, the place of audit and feedback in improving exercise service delivery and overall service implementation
Global Perspectives on Task Shifting and Task Sharing in Neurosurgery.
BACKGROUND: Neurosurgical task shifting and task sharing (TS/S), delegating clinical care to non-neurosurgeons, is ongoing in many hospital systems in which neurosurgeons are scarce. Although TS/S can increase access to treatment, it remains highly controversial. This survey investigated perceptions of neurosurgical TS/S to elucidate whether it is a permissible temporary solution to the global workforce deficit. METHODS: The survey was distributed to a convenience sample of individuals providing neurosurgical care. A digital survey link was distributed through electronic mailing lists of continental neurosurgical societies and various collectives, conference announcements, and social media platforms (July 2018-January 2019). Data were analyzed by descriptive statistics and univariate regression of Likert Scale scores. RESULTS: Survey respondents represented 105 of 194 World Health Organization member countries (54.1%; 391 respondents, 162 from high-income countries and 229 from low- and middle-income countries [LMICs]). The most agreed on statement was that task sharing is preferred to task shifting. There was broad consensus that both task shifting and task sharing should require competency-based evaluation, standardized training endorsed by governing organizations, and maintenance of certification. When perspectives were stratified by income class, LMICs were significantly more likely to agree that task shifting is professionally disruptive to traditional training, task sharing should be a priority where human resources are scarce, and to call for additional TS/S regulation, such as certification and formal consultation with a neurosurgeon (in person or electronic/telemedicine). CONCLUSIONS: Both LMIC and high-income countries agreed that task sharing should be prioritized over task shifting and that additional recommendations and regulations could enhance care. These data invite future discussions on policy and training programs
