The psychological microfoundations of corporate social responsibility: A person-centric systematic review

Abstract: This article aims to consolidate the psychological microfoundations of corporate social responsibility (CSR) by taking stock and evaluating the recent surge of person-focused CSR research. With a systematic review, the authors identify, synthesize, and organize three streams of micro-CSR studies—focused on (i) individual drivers of CSR engagement, (ii) individual processes of CSR evaluations, and (iii) individual reactions to CSR initiatives—into a coherent behavioral framework. This review highlights significant gaps, methodological issues, and imbalances in the treatment of the three components in prior micro-CSR research. It uncovers the need to conceptualize how multiple drivers of CSR interact and how the plurality of mechanisms and boundary conditions that can explain individual reactions to CSR might be integrated theoretically. By organizing micro-CSR studies into a coherent framework, this review also reveals the lack of connections within and between substreams of micro-CSR research; to tackle them, this article proposes an agenda for further research, focused on six key challenges.

Ask for information retrieval: part ii. results of a design study

Abstract: In ‘ASK for Information Retrieval: Part I’, we discussed the theory and background to a design study for an information retrieval (IR) system based on the attempt to represent the anomalous states of knowledge (ASKs) underlying information needs. In Part II, we report the methods and results of the design study, and our conclusions.

Corporate Social Responsibility and Managerial Entrenchment

Abstract: When stakeholder protection is left to the voluntary initiative of managers, relations with social activists may become an effective entrenchment strategy for inefficient CEOs. We thus argue that managerial turnover and firm value are increased when explicit stakeholder protection is introduced so as to deprive incumbent CEOs of activists' support. This finding provides a rationale for the emergence of specialized institutions (social auditors and ethic indexes) that help firms commit to stakeholder protection even in case of managerial replacement. Our theory also explains a recent trend whereby social activist organizations and institutional shareholders are showing a growing support for each others' agenda.

A Network Analysis of the Italian Overnight Money Market

Abstract: The objective of this paper is to analyze, by employing methods of statistical mechanics of complex networks, the network topology of the Italian segment of the European overnight money market. We investigate differences in the activities of banks of different size and the evolution of their connectivity structure over the maintenance period. The main objectives are to understand potential implications of current institutional arrangements on the stability of the banking system and to assess the efficiency of the interbank market in terms of absence of speculative and preferential trading relationships.

Antenatal screening for Down's syndrome

Abstract: Background In 1968 the first antenatal diagnosis of Down's syndrome was made and screening on the basis of selecting women of advanced maternal age for amniocentesis was gradually introduced into medical practice. In 1983 it was shown that low maternal serum alpha fetoprotein (AFP) was associated with Down's syndrome. Later, raised maternal serum human chorionic gonadotrophin (hCG), and low unconjugated oestriol (uE3) were found to be markers of Down's syndrome. In 1988 the three biochemical markers were used together with maternal age as a method of screening, and this has been widely adopted. PRINCIPLES OF ANTENATAL SCREENING FOR DOWN'S SYNDROME: Methods of screening need to be fully evaluated before being introduced into routine clinical practice. This included choosing markers for which there is sufficient scientific evidence of efficacy, quantifying performance in terms of detection and false positive rates, and establishing methods of monitoring performance. Screening needs to be provided as an integrated service, coordinating and managing the separate aspects of the screening process. SERUM MARKERS AT 15-22 WEEKS OF PREGNANCY: A large number of serum markers have been found to be associated with Down's syndrome between 15 and 22 weeks of pregnancy. The principal markers are AFP, hCG or its individual subunits (free alpha- and free beta-hCG), uE3, and inhibin A. Screening performance varies according to the choice of markers used and whether ultrasound is used to estimate gestational age (table 1). When an ultrasound scan is used to estimate gestational age the detection rate for a 5% false positive rate is estimated to be 59% using the double test (AFP and hCG), 69% using the triple test (AFP, hCG, uE3), and 76% using the quadruple test (AFP, hCG, uE3, inhibin A), all in combination with maternal age. Other factors that can usefully be taken into account in screening are maternal weight, the presence of insulin dependent diabetes mellitus, multiple pregnancy, ethnic origin, previous Down's syndrome pregnancy, and whether the test is the first one in a pregnancy or a repeat. Factors such as parity and smoking are associated with one or more of the serum markers, but the effect is too small to justify adjusting for these factors in interpreting a screening test. Urinary markers and fetal cells in maternal blood Urinary beta-core hCG has been investigated in a number of studies and shown to be raised in pregnancies with Down's syndrome. This area is currently the subject of active research and the use of urine in future screening programmes may be a practical possibility. Other urinary markers, such as total oestriol and free beta-hCG may also be of value. Fetal cells can be identified in the maternal circulation and techniques such as fluorescent in situ hybridisation can be used to identify aneuploidies, including Down's syndrome and trisomy 18. This approach may, in the future, be of value in screening or diagnosis. Currently, the techniques available do not have the performance, simplicity, or economy needed to replace existing methods. Demonstration projects Demonstration projects are valuable in determining the feasibility of screening and in refining the practical application of screening. They are of less value in determining the performance of different screening methods. Several demonstration projects have been conducted using the triple and double tests. In general, the uptake of screening was about 80%. The screen positive rates were about 5-6%. About 80% of women with positive screening results had an invasive diagnostic test, and of those found to have a pregnancy with Down's syndrome, about 90% chose to have a termination of pregnancy. ULTRASOUND MARKERS AT 15-22 WEEKS OF PREGNANCY: There are a number of ultrasound markers of Down's syndrome at 15-22 weeks, including nuchal fold thickness, cardiac abnormalities, duodenal atresia, femur length, humerus length, pyelectasis, and hyperechogenic bowel.
