This study aims to deal with the evaluation of institutional development and effectiveness of regional parliaments; it provides a scientific contribution to the development of the field of parliamentary studies by developing a set of indicators to present a parameter for evaluating regional parliaments with application to the Arab Parliament. The study concluded with the development of a parameter of 35 indicators to measure institutionally, efficiency and effectiveness of the institution, with application to the Arab Parliament, as well as developing an integrated assessment of the strengths and weaknesses in the institutional aspects and organizational efficiency.

The study is predicated on the principle of institutional approach and the systems analysis. The curriculum is applied to the Arab Parliament as an institution to quantify efficiency and efficacy according to the implementation of a set of proposed practical indicators. The study additionally applies both Huntington’s institutional standards such as Adaptability, Involution, Autonomy and Coherence, as well as the indicators of institutions efficiency according to PrePanti such as Openness, Reception (R), Autonomy (A), Balance (B), Congruence (C), Internal Efficacy (I), Reformulation (R) and Roles (R), which refer to the first seven Latin letters “First RABCIRR”.

The researcher endeavored to answer the main questions; How to quantify the degree of institutionalization, its impact on the efficiency and efficacy of regional parliaments. The researcher’s approaches and the standards of efficiency and efficacy figured a comprehensive set of indicators that composed an integrated parliamentary standard to assess the degree of institutionalization, efficacy and efficiency of regional parliaments as a scientific contribution based on the Arab Parliament that can be applied to all regional parliaments.

This research is an attempt to create a Parliamentary Index to complement the previous scientific initiatives and efforts in developing such an index, which consists of 35 indicators and its application to the Arab Parliament. This research uses the principles of institutional approach, system analysis methodology and efficiency. The approach is applied to the Arab Parliament as a regional parliament to measure efficiency and effectiveness by applying a set of the proposed indicators.

In response to the COVID-19 pandemic, in 2020–2022, the immutable and fragmented character of our healthcare system changed. Healthcare professionals and their institutional leads proved remarkably agile and managed to change toward collaborative care. The purpose of this paper is to examine experiences with collaborative practice in healthcare during the COVID-19 pandemic in two regions in the Netherlands, to explore and understand the relationship between policy and practice and the potential development of new collaborative care routines.

Using a methodology informed by theories that have a focus on professional working practice (so called “activity theory”) or the institutional decision-makers (discursive institutionalism), respectively, the perspective of physicians on the relationship between policy and practice was explored. Transcripts of meetings with physicians from different institutions and medical specialities about their collaborative COVID-19 care were qualitatively analysed.

The findings show how change during COVID-19 was primarily initiated from the bottom-up. Cultural-cognitive and normative forces in professional, collaborative working practice triggered the creation of new relationships and sharing of resources and capacity. The importance of top-down regulatory forces from institutional leads was less evident. Yet, both (bottom-up) professional legitimacy and (top-down) institutional support are mentioned as necessary by healthcare professionals to develop and sustain new collaborative routines.

The COVID-19 crisis provided opportunity to build better healthcare infrastructure by learning from the responses to this pandemic. Now is the time to find ways to integrate new ways of working initiated from the bottom-up with those longstanding ones initiated from top-down.

This paper presents a combination of theories for understanding collaboration in healthcare, which can inform future research into collaborative care initiatives.

The purpose of this paper is to prepare stabile emulsions with 0–15% of colloidal silica and high monomer/water ratio and to investigate the influence of silica addition and surface modification on the polyacrylate properties.

Improving the properties of the composite can be achieved by optimizing the compatibility between the phases of the composite system with improving the interactions at the matrix/filler interface. Therefore, the silica surface was modified with nonionic emulsifier octylphenol ethoxylate, cationic initiator 2,2'-azobis-(amidinopropane dihydrochloride) and 3-methacryloxypropyltrimethoxysilane and polyacrylate/silica nanocomposites were prepared via in situ emulsion polymerization. Particle size distribution, rheological properties of the emulsions and morphology, thermal properties and mechanical properties of the film prepared from the emulsions were investigated.

Polyacrylate/silica systems with unmodified silica, silica modified with nonionic emulsifier and cationic initiator have micrometer, while pure PA matrix and systems with silica modified with silane have nanometer particle sizes. Addition and surface modification of the filler increased emulsion viscosity. Agglomeration of silica particles in composites was reduced with silica surface modification. Silica filler improves thermal stability and tensile strength of polyacrylate.

This paper provides broad spectrum of information depending on filler surface modification and latex preparation via in situ emulsion polymerization and properties with high amount of filler and monomer/water ratio with the aim that prepared latex is suitable for film formation and final application.
