Abstract

In published work on hedonic house price estimation it is not uncommon to examine some of the conditions required for the estimators to have desirable properties such as minimum variance and unbiasedness, in particular spatial autocorrelation. However, other conditions that can give rise to similar difficulties with the estimates are often ignored. If these technical conditions are not met, it is sometimes because the model is misspecified in some way. This paper argues that a wider range of diagnostic statistics should be used in the specification search for a good model, in particular, but not exclusively, those concerned with predictive stability. The paper illustrates this approach by examining both in‐sample and out‐of‐sample diagnostic tests of various specifications of a hedonic house price model using data taken from the sale of over 1,600 properties in the Midlands of the UK in 1999/2000. The models investigated include various specifications of the dependent and independent variables, including models that are non‐linear in the parameters. The paper concludes that such statistics can often help in model selection and should be more widely employed.

Abstract

THE New Year should be one of much progress in the organization of Librarianship. We wish our readers all the pleasure and prosperity that may come from increasing activity and growing public esteem. Every year we are able to record some progress in the general estimate in which the work of libraries is held; we have not reached, and do not even approximate, to the efficiency and perfect service that we desire to attain and to render; but we believe that the library movement is on the right road.

Abstract

In its passage through the Grand Committee the Food Bill is being amended in a number of important particulars, and it is in the highest degree satisfactory that so much interest has been taken in the measure by members on both sides of the House as to lead to full and free discussion. Sir Charles Cameron, Mr. Kearley, Mr. Strachey, and other members have rendered excellent service by the introduction of various amendments; and Sir Charles Cameron is especially to be congratulated upon the success which has attended his efforts to induce the Committee to accept a number of alterations the wisdom of which cannot be doubted. The provision whereby local authorities will be compelled to appoint Public Analysts, and compelled to put the Acts in force in a proper manner, and the requirement that analysts shall furnish proofs of competence of a satisfactory character to the Local Government Board, will, it cannot be doubted, be productive of good results. The fact that the Local Government Board is to be given joint authority with the Board of Agriculture in insuring that the Acts are enforced is also an amendment of considerable importance, while other amendments upon what may perhaps be regarded as secondary points unquestionably trend in the right direction. It is, however, a matter for regret that the Government have not seen their way to introduce a decisive provision with regard to the use of preservatives, or to accept an effective amendment on this point. Under existing circumstances it should be plain that the right course to follow in regard to preservatives is to insist on full and adequate disclosure of their presence and of the amounts in which they are present. It is also a matter for regret that the Government have declined to give effect to the recommendation of the Food Products Committee as to the formation of an independent and representative Court of Reference. It is true that the Board of Agriculture are to make regulations in reference to standards, after consultation with experts or such inquiry as they think fit, and that such inquiries as the Board may make will be in the nature of consultations of some kind with a committee to be appointed by the Board. There is little doubt, however, that such a committee would probably be controlled by the Somerset House Department; and as we have already pointed out, however conscientious the personnel of this Department may be—and its conscientiousness cannot be doubted—it is not desirable in the public interest that any single purely analytical institution should exercise a controlling influence in the administration of the Acts. What is required is a Court of Reference which shall be so constituted as to command the confidence of the traders who are affected by the law as well as of all those who are concerned in its application. Further comment upon the proposed legislation must be reserved until the amended Bill is laid before the House.

Abstract

Purpose

To evaluate the effectiveness of an adaptation of Interpersonal Group Psychotherapy (IPT-G), in facilitating short- and longer-term improvements in eating disorder symptomology, psychosocial impairment, anxiety, depression and attachment difficulties among adults living with overweight and diagnosed with binge eating disorder (BED).

Design/methodology/approach

In total, 24 participants completed measures at the start of IPT-G, mid-treatment, discharge and six-month follow-up. Quantitative outcomes were analysed utilising one-way repeated measures analysis of variance.

Findings

Treatment retention was 100%. Significant improvements in binge-eating frequency, psychosocial impairment and depression were achieved at mid-treatment and maintained at post-treatment and six-month follow-up, and with large effect sizes. Attachment anxiety had reduced significantly at post-treatment and was maintained at six-month review. Body mass index (BMI) had stabilised by mid-treatment and was maintained at post-treatment and six-month follow-up. All hypotheses were supported, with the exception that attachment avoidance did not improve significantly and following a post-treatment reduction, anxiety symptoms deteriorated slightly by six-month follow-up, such that they were no longer significantly different from pre-treatment levels.

Practical implications

Despite being the most prevalent of the eating disorders (compared to anorexia nervosa and bulimia nervosa), BED is under-recognised and under-treated in clinical settings. Results indicate the sustained effectiveness of IPT-G in improving eating disorder and comorbid symptomology associated with BED.

Originality/value

This is the first UK study to investigate the effectiveness of IPT-G at treating BED. Unlike previous studies in the field, this study did not exclude participants based on age, BMI or psychiatric comorbidity.
