This paper seeks to explore varied interrelated challenges and barriers experienced by immigrant seniors.

Senior immigrants representing diverse ethnicities (Chinese, Afro Caribbean, Former Yugoslavian, Spanish) described their challenges, support needs, and barriers to service access. Service providers and policy makers from organizations serving immigrant seniors were interviewed to elicit their views on barriers to access and appropriateness of services for immigrant seniors. Qualitative methods were employed to enhance understanding of meanings, perceptions, beliefs, values, and behaviors of immigrant seniors, and investigate sensitive issues experienced by vulnerable groups. The qualitative data were subjected to thematic content analysis.

Seniors reported financial and language difficulties, health problems, discrimination, family conflicts, and social isolation. Although most immigrant seniors appreciated the standard of living in Canada and the services provided to seniors, most believed that support received was inadequate. Seniors encountered systemic (e.g. government policies), institutional (e.g. culturally inappropriate programs), and personal (e.g. transportation, language problems) barriers to accessing social and health services. Service providers and policy makers faced high costs of programs, inadequate financial and human resources, inadequate information about needs of immigrant seniors, inadequate geographical coverage, and lack of inter‐sectoral collaboration.

The challenges experienced by immigrant seniors have implications for programs and policies and can inform the development of culturally sensitive and appropriate services.

The barriers encountered by service providers in assisting immigrant seniors point to the importance of inter‐sectoral coordination, cultural sensitivity training, and expansion of service providers' mandates.

This study revealed numerous unmet needs for successful acculturation of immigrant and refugee seniors in Canada. It also reveals that the most cogent and sustainable approach to close this chasm of support deficits, unattended challenges, and complex stressors is to implement a model that simultaneously addresses the three levels and use a multisectoral approach.

The aim of this study is to investigate the influence of Project Management Office (PMO) functions on project performance in businesses in Lower Middle-Income Countries (LMIC) using Partial Least Square–Structural Equation Modelling (PLS–SEM).

Utilizing close-ended questionnaires in a cross-sectional survey, 256 project professionals from 10 business sectors in Ghana views were elicited. The questions were developed through a comprehensive literature review and involved 27 PMO functional measures grouped into 6 and 19 project performance measures grouped into 6. Data collected was then analysed using the PLS–SEM to validate the hypothetical relationship.

The PLS–SEM model supported 13 (t > 1.65) out of 36 hypotheses investigating the relationship between PMO functions and project performance. Variations in the PMO functions moderately (R2 = 0.34) explained the performance of projects. The aggregate activities of the PMO had the highest significant influence on environmental performance (R2 = 0.467). The topmost PMO function was identified as monitoring and controlling project performance, and it was significantly associated with cost (ß = 0.265, p < 0.05), quality (ß = 0.291, p < 0.05) and project scope (ß = 0.265 p < 0.05) performance.

This research has brought more illumination to the functions of PMOs and its influence on project performance. The results suggest that PMO activities, when tailored to the business context, can significantly change project performance variables.

Most research on PMO and project performance has been limited to developed countries or a single sector. This study uniquely expands the business sectors and focuses on LMICs.
