Over the past decade there has been a growing literature on project success criteria, however there has been relatively little empirical data. This paper provides a significant contribution to the knowledge of project success by providing empirical data on the subject, by means of a survey of 150 Australian project managers on the subject of project success criteria. An analysis of the data found two distinct views: those that perceived project success solely in terms of the traditional project objectives of time, cost and quality; and those that considered success in terms of these objectives and the effectiveness of the project's product. The traditional project management success criteria of time, cost and quality still has a strong hold within the project management community in Australia. However, the most important success criterion was considered to be the product success criterion of meeting the owner's needs.

The protein structure prediction problem has been solved for many types of proteins by AlphaFold. Recently, there has been considerable excitement to build off the success of AlphaFold and predict the 3D structures of RNAs. RNA prediction methods use a variety of techniques, from physics-based to machine learning approaches. We believe that there are challenges preventing the successful development of deep learning-based methods like AlphaFold for RNA in the short term. Broadly speaking, the challenges are the limited number of structures and alignments making data-hungry deep learning methods unlikely to succeed. Additionally, there are several issues with the existing structure and sequence data, as they are often of insufficient quality, highly biased and missing key information. Here, we discuss these challenges in detail and suggest some steps to remedy the situation. We believe that it is possible to create an accurate RNA structure prediction method, but it will require solving several data quality and volume issues, usage of data beyond simple sequence alignments, or the development of new less data-hungry machine learning methods.

Project success is one of the widely discussed issues inside Project Management field in the last decades. Success criteria (SC) and critical success factors (CSFs) constitute the two fundamental components of project success. The aim of this paper is the identification and evaluation of the SC as well as the CSFs in project success in theory and practice. A detailed literature review and content analysis are used to identify the frequency of reference of SC and CSFs, while an extensive questionnaire survey in individuals and organizations with experience in construction projects in Greece is performed to investigate their importance in project success. Regarding the relative importance, according to respondents’ perceptions, cost/budget, time/schedule, client/user satisfaction, and quality and technical performance are the most important SC, while project finance/funding and economics, project team/team members ability/competence and effectiveness, and project manager/team leader ability/competence and relative/past experience are the most important CSFs. The first four SC present similarities in terms of citation frequency in the literature review and relative importance provided by the respondents, while the ranking of the rest SC and CSFs presents several deviations. The Spearman correlation coefficient is used to investigate the possible relationships among the SC and the CSFs. 5 out of 17 SC and 11 out of 26 CSFs present low or moderate correlations (rs < 0.5) respectively. The present research can serve as the basis for developing either a mathematical model or performance index for evaluating success of construction projects.

Facebook is the world's most wildly successful media company that neither produces nor owns any content. Airbnb is the world's most wildly successful hotel company that neither buys nor owns property. Uber is the world's most wildly successful transportation company that owns no cars. Alibaba is the world's most wildly successful retail company that owns no inventory. Academic publishers must follow suit - or so say the industry gurus, the barons of third-party funding, the rajas of professional societies, and the high priests of power within academic publishing itself. Publishers must become software companies without any books.

The term tertiary succession which follows restoration measures was introduced recently as a complement to primary and secondary succession. However, its widespread use is not justified ecologically. It seems rather formalistic and does not contribute to a better linking of successional theory and practical ecological restoration. The arguments questioning the use of this term are summarized here.

This study investigates the breeding success of two tropical seabirds that exploit dissimilar nesting habitats on Cousine Island in the Seychelles archipelago, the White Tern Gygis alba and the White-tailed Tropicbird Phaethon lepturus, which nest in trees and in crevices on the ground, respectively. Both species have a clutch of one egg. Over a 23-month study period, the outcomes of 134 nesting attempts by White Terns and 285 by White-tailed Tropicbirds were followed. White Terns produced an average of 0.4 chicks per attempt, significantly more than that of White-tailed Tropicbirds (0.25). Hatching success did not differ between the two species, but fledging success of White Terns (62%) was significantly higher than that of White-tailed Tropicbirds (43%). Nesting success of White-tailed Tropicbirds may be less successful than White Terns because their ground nests are at risk to purely terrestrial predators, in addition to predators that are both terrestrial and arboreal. Many nests of White-tailed Tropicbirds failed during the first two weeks of the incubation and nestling periods, but the reasons for this are unclear. Food availability may influence the reproductive success of both species.

Organisations have high expectations that the Information Systems (IS) projects they undertake will be successful. IS projects typically involve a variety of stakeholders who may have inherently different definitions of project success. It is perhaps due to the perceived engineering aspects of IS projects that a heightened sense of inescapable IS project success is omnipresent. The study relies on a grounded theory approach to advance a theory of and provide an explanation for, the expectations of IS project success within organisations. This study found that more often than not high expectations for IS project success stem from intrinsic personal factors.

P>The influence of parasitism on first-year growth and recruitment success of two cyprinid species in the Yorkshire Ouse catchment, England, was investigated using a 14-year dataset. This study demonstrated a significant role of parasitism in growth and recruitment success of roach, Rutilus rutilus (L.), and European chub, Squalius cephalus (L.) populations. Muscle infections by Bucephalus polymorphus Baer (Digenea), Myxobolus pseudodispar Gorbunova (Myxozoa) and Myxobolus pfeifferi Thelohan were considered important, with significant relationships between these parasites and year-class strength and age-0 fish length. Other parasites, such as Phyllodistomum sp. and Goussia sp., were implicated in host success to a lesser extent. Parasitism may be a major factor in recruitment and account for a high proportion of the variation in year-class strength, although this varied among locations.

This article focuses on hybrid succession teams that comprise both family and nonfamily members, to identify the reasons and criteria for forming these teams, as well as the difficulties they encounter during the succession process. The empirical results, based on three longitudinal case studies (two failures and one success), reveal the strong and sometimes negative influence of the predecessor on the constitution and functioning of these succession teams. In particular, the predecessor may choose this form of succession and the members of the team, based solely on the complementarity of their skills. The predecessor's natural preference for family members also can be a source of conflict, because it creates information asymmetry between family and nonfamily successors. Consequently, a lack of strong ties among team members and the presence of information asymmetry can increase the risk of succession team dissolution.
