SEGMENTATION OF HOUSEHOLDS AND RESIDENTIAL BEHAVIOUR

ABSTRACT Residential behaviour in a large Italian region is investigated focusing on tenants' judgement about their present condition and, if negative, the decision whether to move or stay. Housing needs and tastes, which explain residential mobility, are assumed to vary with households’characteristics. The paper suggests a specific procedure to find the relevant demand segments. A distinct logit model for each segment tries to explain satisfaction for current dwelling. For unsatisfied households, the propensity to move is modelled as a function of both level of dissatisfaction and factors expressing inertia.

The impact of international migration on the urban structure of Amman

L'impact des migrations internationales sur la structure urbaine d'amman Peu de pays exportateurs de main-d'œuvre sont aussi profondément touchés par la migration internationale que la Jordanie. En 1976, les transferts de revenus des travailleurs migrants ont représenté 24% du Produit National Brut. Cette communication examine l'influence de la migration internationale sur l'urbanisation, en étudiant premièrement la nature de l'émigration jordanienne et palestinienne et l'impact des investissements immobiliers des travailleurs migrants. Deuxièmement, la communication analyse les résultats d'une enquête à Amman qui a essayé d'identifier les manifestations morphologiques de l'urbanisation résultant de l'utilisation des transferts de revenus pour le logement.

DWELLING ENERGY EFFICIENCY AND HOME ENERGY CONSERVATION POLICIES: A WESTERN U.S. PERSPECTIVE

The purpose of this study was to examine the energy beliefs of western U.S. residents. Data from the Western Regional Project W‐159, ‘Consequences of Energy Conservation Policies for Western Region Households' were analysed. Using a sample of 5,471, respondents' beliefs about the energy efficiency of their current dwelling and actual energy saving features were compared. A significant Kendall correlation was found and these two measures were then used to divide the sample into two groups, respondents with energy efficient dwellings and respondents with energy inefficient dwellings. Chi‐square analyses yielded significant differences between the two subsamples' beliefs about the seriousness of the U.S. energy problem and whether to solve it by conserving energy or increasing production. The two sub‐samples' beliefs about a series of mandatory and incentive energy conservation policies were compared. For all policies except requiring home energy audits, significant differences were found between the two subsamples' beliefs. Overall, the incentive energy conservation policies were favoured over the mandatory policies. Sample respondents with energy efficient dwellings were more often opposed or strongly opposed to the incentive policies than were the respondents with energy inefficient dwellings.

Spatial aspects of intraurban migration behaviour in a mixed housing market.

This paper examines the validity of J S Adams's propositions concerning the spatial properties of overt migration behaviour in the context of a British city (that is, Birmingham) with a significant public housing sector. Samples of migration moves associated with separate housing submarkets, identified on the basis of tenure/dwelling type criteria, are tested for sectoral, directional, and distance biases. Mean movement distances are computed to measure distance bias, and sectoral and directional biases are assessed by two move-angle models: (1) a uniform vacancy model, and (2) a weighted vacancy model which controls for the effects of a vacancy surface on migration patterns. In general, the results suggest that support for Adams's propositions is limited to moves associated with submarkets either in the private or in the public housing sectors characterized by relatively high levels of tenure security. It is concluded that locational preferences usually assume a low priority in migration decisionmaking when households are only temporarily committed to their current dwellings.

Observed Dwells in Current through a Pulsed Argon Plasma

Current dwells of durations from 1 to 38μsec have been observed with capicator-discharge, argon plasmas pulsed in vacuo. The current during dwell is zero with a measuring error of 1 A in contrast to large dwell currents observed in plasma of exploded wires.

Generation of High Power Radio-Frequency Pulses by Means of an Exploding Wire Technique

A method of generating high power radio-frequency pulses is described which utilizes the ``current dwell'' period which can occur when a thin wire is exploded by means of a high current. The rf oscillation occurs in a resonant circuit placed in series with the exploding wire. A circuit is described in which is obtained a 6-μsec duration pulse of 2.74-Mc oscillations.

Design of Resistance Welder Transformers

Due to increased production demands, the speed at which resitance welders operate has been stepped up as much as four to five times during the last few years. This has been made possible in a large degree, by the development of new switching mechanisms that will allow a current dwell of a fraction of a cycle on a 60-cycle circuit. This increased speed of welding has made it necessary to study very carefully the design of the transformer and the shape and spacing of the secondary circuits, especially the cooling and protection of these parts. It has been necessary also to pay more attention to multi-transformer welders, where several transformers are used either for the purpose of distributing the secondary current to better advantage, or for the purpose of balancing the welder load on multi-phase circuits.
