Various concepts of interaction are reconsidered in light of a su¢ cient-component cause framework. Conditions and statistical tests are derived for the presence of synergism within su¢ cient causes. The conditions derived are su¢ cient but not necessary for the presence of synergism. In the context of monotonic e¤ects, but not in general, the conditions which are derived are closely related bu...

Abstract Interviewing of suspects, victims, and eyewitnesses contributes significantly to the investigation process. While a great deal is known about investigative interviewing practices in United Kingdom Nordic region, very little framework used by Malaysian police officers. A survey was administered 44 Royal Police interviewers serving Sexual, Women Child Investigations Division (D11) Crime ...

A 71-year-old woman on warfarin (2.5 mg daily) developed severe low back pain with reduced touch sensation and weakness of the lower limbs that progressed to complete paralysis within 28 to 30 hours. Imaging revealed bleeding at the D4 through D11 level, however the patient refused emergency laminectomy. No recovery was observed and the patient was discharged to a rehabilitation facility. Only ...

Using non-parametric weak separability tests that are extended to allow for measurement errors in the data, a broad group of UK monetary assets is found to be weakly separable from consumer goods and leisure over the larger part of the nineties. Financial innovations have made assets with substantial interest rate risk (e.g. unit trusts) more liquid and recent developments in monetary aggregati...

A theory of decision making is proposed that offers an axiomatic basis for the notion of “satisficing” postulated by Herbert Simon. The theory relaxes the standard assumption that the decision maker always fully perceives his preferences among the available alternatives, requiring instead that his ability to perceive any given preference be decreasing with respect to the complexity of the choic...

The reports of glomerular lesions of kidney due to tuberculosis are sparse. A 48-year-old gentleman, presented with swelling of feet of 3 months duration. As he had renal impairment, proteinuria and normal-sized kidneys, he was subjected to renal biopsy. The light microscopy and immunofluorescence revealed the diagnosis was membrano-proliferative glomerulonephritis. During hospital stay, the pa...

Motivated by the empirical findings concerning the importance of one’s current situation on her choice behavior, the main objective of this paper is to propose a rational choice theory that allows for the presence of a status quo bias, and that incorporates the standard choice theory as a special case. We follow a revealed preference approach, and obtain two nested models of rational choice tha...

For a large class of additive random utility discrete choice models with income effects, we compute the probability distribution of the compensating variation. We show that the cumulative distribution function only depends on the choice probabilities. Our results are used to compute the distribution of equivalent variation. The moments of the compensating variation are a onedimensional integral...

The analysis of lab data entails a joint test of the underlying theory and of subjects’ conjectures regarding the experimental design itself, how subjects frame the experiment. We provide a theoretical framework for analyzing such conjectures. We use experiments of decision making under uncertainty as a case study. Absent restrictions on subjects’ framing of the experiment, we show that any beh...

Topological separability is crucial for the utility representation of a complete preference relation. When preferences are incomplete, this axiom has suitably de…ned counterparts: upper separability and lower separability (Ok (2002)). We consider the problem of representing an incomplete preference relation by means of a vector-valued utility function; we obtain representation results under the...
