Etude biostratigraphique du cretace inferieur (Barremien Superieur-Albien) du haut atlas occidental (Maroc)

The lower Cretaceous (mainly Upper Barremian and Albian) of the Westem High Atlas of Morocco displays a diversified fauna constitued by Ammonite, Ostracoda, and foraminifera. The analysis of the microfauna, especially the planctonic foraminifera, allowed the characterization of various lithologic units, and their subdivision and datation. We have identified different biozona with planctonic foraminifera typical of the Tethysian realm characterising the Upper Barremian to the Albian. These biozona are described and their limits are discussed.Les affleurements du Crétacé inférieur, et principalement le Barrémien supérieur- Albien du Haut Atlas occidental marocain, ont fourni une faune diversifiée constituée par des ammonites, des ostracodes et des foraminifkres.

Facilitators and Barriers to Participation in a Peer Support Intervention for Veterans With Chronic Pain

OBJECTIVE: To understand facilitators and barriers to participation in a peer support intervention for self-management of chronic pain. METHODS: After completing a pilot intervention study, peer coaches and their veteran patients took part in a qualitative, semistructured interview to explore their experiences with the intervention. Data were analyzed using an immersion/crystallization approach. RESULTS: Three facilitators and 2 barriers to patient participation in a peer support intervention for veterans with chronic pain emerged. Facilitators were (1) having a shared identity as veterans, (2) being partnered with a person who also has chronic pain, and (3) support from the study staff. Barriers were (1) logistical challenges, and (2) challenges to motivation and engagement in the intervention. DISCUSSION: Awareness of facilitators and barriers to participation in a peer-supported self-management program for chronic pain, as well as strategies to capitalize on facilitators and mitigate barriers, are essential for further study and ultimate clinical implementation of such a program

Systematic review on human resources for health interventions to improve maternal health outcomes: Evidence from low- and middle-income countries

There is a broad consensus and evidence that shows qualified, accessible, and responsive human resources for health (HRH) can make a major impact on the health of the populations. At the same time, there is widespread recognition that HRH crises particularly in low- and middle-income countries (LMICs) impede the achievement of better health outcomes/targets. In order to achieve the Sustainable Development Goals (SDGs), equitable access to a skilled and motivated health worker within a performing health system is need to be ensured. This review contributes to the vast pool of literature towards the assessment of HRH for maternal health and is focused on interventions delivered by skilled birth attendants (SBAs). Studies were included if (a) any HRH interventions in management system, policy, finance, education, partnership, and leadership were implemented; (b) these were related to SBA; (c) reported outcomes related to maternal health; (d) the studies were conducted in LMICs; and (e) studies were in English. Studies were excluded if traditional birth attendants and/or community health workers were trained. The review identified 25 studies which revealed reasons for poor maternal health outcomes in LMICs despite the efforts and policies implemented throughout these years. This review suggested an urgent and immediate need for formative evidence-based research on effective HRH interventions for improved maternal health outcomes. Other initiatives such as education and empowerment of women, alleviating poverty, establishing gender equality, and provision of infrastructure, equipment, drugs, and supplies are all integral components that are required to achieve SDGs by reducing maternal mortality and improving maternal health

Impact of service provision platforms on maternal and newborn health in conflict areas and their acceptability in Pakistan: a systematic review

Various models and strategies have been implemented over the years in different parts of the world to improve maternal and newborn health (MNH) in conflict affected areas. These strategies are based on specific needs and acceptability of local communities. This paper has undertaken a systematic review of global and local (Pakistan) information from conflict areas on platforms of health service provision in the last 10 years and information on acceptability from local stakeholders on effective models of service delivery; and drafted key recommendations for improving coverage of health services in conflict affected areas. The literature search revealed ten studies that described MNH service delivery platforms. The results from the systematic review showed that with utilisation of community outreach services, the greatest impacts were observed in skilled birth attendance and antenatal consultation rates. Facility level services, on the other hand, showed that labour room services for an internally displaced population (IDP) improved antenatal care coverage, contraceptive prevalence rate and maternal mortality. Consultative meetings and discussions conducted in Quetta and Peshawar (capitals of conflict affected provinces) with relevant stakeholders revealed that no systematic models of MNH service delivery, especially tailored for conflict areas, are available. During conflict, even previously available services and infrastructure suffered due to various barriers specific to times of conflict and unrest. A number of barriers that hinder MNH services were discussed. Suggestions for improving MNH services in conflict areas were also laid down by participants. The review identified some important steps that can be undertaken to mitigate the effects of conflict on MNH services, which include: improve provision and access to infrastructure and equipment; development and training of healthcare providers; and advocacy at different levels for free access to healthcare services and for the introduction of the programme model in existing healthcare system. The obligation is enormous, however, for a sustainable programme, it is important to work closely with both the IDP and host community, and collaborating with the government and non-government organisations

Luminescence studies on green emitting InGaN/GaN MQWs implanted with nitrogen

We studied the optical properties of metalorganic chemical vapour deposited (MOCVD) InGaN/GaN multiple quantum wells (MQW) subjected to nitrogen (N) implantation and post-growth annealing treatments. The optical characterization was carried out by means of temperature and excitation density-dependent steady state photoluminescence (PL) spectroscopy, supplemented by room temperatura PL excitation (PLE) and PL lifetime (PLL) measurements. The as-grown and as-implanted samples were found to exhibit a single green emission band attributed to localized excitons in the QW, although the N implantation leads to a strong reduction of the PL intensity. The green band was found to be surprisingly stable on annealing up to 14006C. A broad blue band dominates the low temperature PL after termal annealing in both samples. This band is more intense for the implanted sample, suggesting that defects generated by N implantation, likely related to the diffusion/segregation of indium (In), have been optically activated by the thermal treatmentThe authors acknowledge FCT for the final funding from PEst-C/CTM/LA0025/2013-14, PTDC/CTM-NAN/2156/2012, PTDC/FIS-NAN/0973/2012 and RECI/FIS-NAN/0183/ 2012 (FCOMP-01-0124-FEDER-027494) projects.

Why has not it worked? An empirical application of the extended Burns and Scapens' framework within the implementation of a controlling department

ABSTRACT The aim of this study is to understand the implementation of a controlling department within Bogt and Scapens' framework (2014) as an empirical observation mechanism towards investigating rationalities that prevented its implementation. This study was conducted in a quite successful 63-year old company in the South of Brazil. We hope these results promote practical insight to those interested in supporting changes within this field of organizational environment. There had been two main reasons leading to such work: a lack of equivalent study in the scholarly literature as well as empirical application of Burns and Scapens' framework (2000) reorganized by Bogt and Scapens (2014). Bogt and Scapens (2014), inspired by different logics (Bogt & Scapens, 2012) and in order to revaluate their original framework (2000), suggest the introduction of a fairly important term: rationality. This new element shows the deliberate action from the organizational player - his/her way of thinking. However, even with the introduction of rationales within the model by Bogt and Scapens (2014), rules and routines remain as important elements so that actions take shape. Used methodology consists of an interpretational case study with document analysis, direct observation, and application of semi-structured interviews. Through the interviews and discussions with individuals involved in the study, it can be observed that some rationality resulted in conflicts. Different rationales and the culture of the individual and the organization are relevant aspects observed in the speeches analyzed; all may be factors, which led to the gap within the process of implementation of controlling department in the organization. In addition, time factors suggested in the extended Bogt and Scapens' (2014) framework is of utmost importance for changes must occur gradually
