Purpose This study aims to explore the principles and practices for managing records with the lens of functional analysis and knowledge management by using a case study that focuses on the experience of implementing records management at a public high school in Hong Kong. Design/methodology/approach A single case study is chosen as the research method for this paper. A series of qualitative interviews and documentary analysis were used to collect and triangulate the qualitative data. Findings The results show that the case school adopted a hybrid top-down and bottom-up approach to record management, facilitate decision-making and manage knowledge. The school adopted the taxonomy provided by the quality assurance framework as the functional classification in a digital archive in the records management system. Practical implications This study provides a set of taxonomy and a hybrid top-down and bottom-up approach to schools for ensuring that accurate information of all school activities is kept and can facilitate an effective and evidence-based, decision-making process. Social implications Identifying taxonomy and management practices for effective documentation in public schools can support planning, assist with organising the continuity of improvement plans and increase reporting and accountability to society. Originality/value This study offers a taxonomy and management approach to the literature of records management and the practices for promoting and improving records management in school.

While the NHS has expressed a commitment to innovation with a succession of dedicated 'arms length bodies,' there are numerous high-profile cases in which advances on the ground have not received as much support as they might. In his recent Next Stage Review report, Lord Darzi has emphasised a commitment to clinical decision-making at all levels of the NHS but whether this will involve embracing best practice from the bottom up remains to be seen. For this article I spoke to two surgeons, whose sometimes controversial innovations were admired by many, about the obstacles they faced.

Though communal orientation impacts how people interact, and members’ interactions influence interdependent decision-making, communal orientation’s impact on interdependent decision-making has received little attention. We address this by applying interdependence theory to take a bottom-up approach across three studies. We find that individuals who are higher on communal orientation are less likely to use prohibitive voice. We also show that dyadic communal orientation harms interdependent decision performance by lowering the amount of prohibitive voice used. At the team level, we find that team communal orientation is negatively related to interdependent decision performance unless the team is also high on relationship orientation diversity, which has a positive effect on interdependent decision performance. Combined, these studies contribute to the communal orientation literature by extending it to an important context—interdependent decision-making—and helping it be more balanced by demonstrating communal orientation’s downside.

NGOs deploy multiple approaches to achieve their objectives. These may broadly be classified as bottom up and top down. While a bottom-up approach emphasises local decision making, community participation and grassroots mobilisation/movements, the top-down approach focuses on lobbying and bargaining with the decision-making authorities such as government agencies, building up of pressures through various campaign mechanisms, advocacy activities, etc. This article draws insights from the literature and begins with a discussion on approaches undertaken by grassroots NGOs to meet their objectives. At the outset, the article ponders over a set of questions such as whether grassroots NGOs essentially follow a bottom-up approach. If so, why? Do they also intend to establish rapport with the state officials and thereby have say in the decision-making process? If so, how do they pursue it? This article, however, operationalises the bottom-up approach in terms of an array of indicators such as awareness building efforts of NGOs, people's participation in different phases of projects, and people's involvement in creating people's institutions. Similarly, it defines top-down approach on the basis of indicators such as NGOs’ participation in advocacy activity, obtaining support from government authority and obtaining favourable court verdicts. Despite the rhetoric, this article conclusively finds that no grassroots NGO practices either a bottom-up or top-down approach exclusively.

We review a series of models of sociophysics introduced by Galam and Galam et al. in the last 25 years. The models are divided into five different classes, which deal respectively with democratic voting in bottom-up hierarchical systems, decision making, fragmentation versus coalitions, terrorism and opinion dynamics. For each class the connexion to the original physical model and techniques are outlined underlining both the similarities and the differences. Emphasis is put on the numerous novel and counterintuitive results obtained with respect to the associated social and political framework. Using these models several major real political events were successfully predicted including the victory of the French extreme right party in the 2000 first round of French presidential elections, the voting at fifty–fifty in several democratic countries (Germany, Italy, Mexico), and the victory of the "no" to the 2005 French referendum on the European constitution. The perspectives and the challenges to make sociophysics a predictive solid field of science are discussed.

The product design process plays a central role in ensuring that new products are realized with improved quality, in a short lead-time and with costs kept to a minimum. It is identified that making decisions dynamically on how the design process should proceed is not trivial. A computational environment that aids dynamic decision making on the design process would be useful in ensuring successful design of new products. A key component of analysing and making decisions on the progression of the design process is a model that captures an ongoing design process. In this paper, an approach to modelling an ongoing design process is proposed based on the use of design nodes. The approach allows an ongoing design process to be modelled that facilitates dynamic decision making on how the design process should progress and accounts for the state of the design problem. The approach allows top-down and bottom-up design strategies to be modelled.

One of the interesting research questions in multi-attribute decision-making is what affects the consideration of shared information (i.e., common features) between two alternatives. Previous studies have suggested two approaches (bottom-up and top-down) in finding what characteristics of common features affect their consideration. Two bottom-up factors (salience and interdependence) were found, but no top-down factors were discovered. In the current study, we followed the top-down approach and investigated how subjective importance (SI) of a common feature affects its consideration. In two studies, we consistently found that, on both the general and individual level, the level of consideration increased with the SI of the common feature. This result provided a new explanation for the effect of common feature consideration and its individual difference; it also provided insights in explaining the underlying process of multi-attribute decision making.
