The addition of thermal insulation into attics along with air-tightening of the ceiling plane is a common first step in making homes more energy efficient. Attic ventilation was introduced decades ago on the assumption that air leakage across the ceiling was inevitable and not correctible – this was before the era of spray-applied foams. Often attic ventilation is provided at roof eaves, and ensuring good insulation in their location is critical to avoid cold corners in the rooms below. So may vents be blocked in the course of energy retrofits? The paper aims to discuss this issue.

This study consists of a simple spreadsheet model of attic performance. The model is built using material from ASHRAE Handbook Fundamentals and ASHRAE Standards. It includes: Glaser calculations for temperature, vapor pressure and vapor pressure excess; radiation exchange – solar and sky; buoyancy flow assumption for leakage from indoors; wind flow assumption for leakage from outdoors; and change in attic air RH as assumed indicator of change in sheathing moisture performance.

The model results show that lowered moisture contributions across air-tightened ceilings may compensate effectively for added insulation (which lowers the attic air temperature) and reduced moisture dilution from attic ventilation.

These results provide support for the policy of allowing attic ventilation reductions that are proportionate to ceiling air leakage reductions as part of weatherization efforts. Given the limitations of the model, continued field observations remain critical.

The growth of last-mile delivery presents challenges like environmental impact, operational inefficiencies and risks of theft or damage. This study explores parcel locker adoption as a potential solution, focusing on the roles of information framing and consumer characteristics in influencing consumer adoption. It offers insights into prioritizing benefits (environmental, security, convenience) in information framing and which consumer traits, such as regulatory focus and gender, to consider in designing and promoting parcel locker networks.

We test our hypotheses with three scenario-based experiments. The first focuses on the key parcel locker benefit of environmental sustainability framing, the second on security framing and the third on convenience framing.

Our results show that consumers are more likely to use parcel locker delivery when exposed to loss-framed environmental or security information, particularly when they are male. Additionally, promotion-focused individuals, particularly males, are the most likely users when presented with loss-framed messages emphasizing the inconvenience and insecurity of home delivery.

Our findings produce a middle range theory of gender and regulatory focus in the context of consumer participation in parcel locker delivery. Specifically, we find that gender and regulatory focus influence consumer reactions to information disclosure, with loss-framed information more strongly influencing consumer intent for promotion-focused individuals.

Managers seeking to introduce parcel lockers or expand existing parcel locker networks should incorporate security and convenience into their locker network decisions. Initial locker bays should be located in or near sites that experience high consumer traffic from promotion-focused males. Additionally, information disclosed should highlight these security and convenience benefits compared to the relative inconvenience and risk associated with home delivery.

While information disclosures often emphasize the environmental benefits associated with parcel locker use, likely users find other benefits more convincing. Highlighting these alternative factors and incorporating them into parcel locker network design will still allow for environmental benefits, including carrier CO2 reduction, to emerge from increased parcel locker use. As locker networks become more established, expanding the network to cater to additional consumers may allow service providers to focus information on environmental benefits.

Prior research assumes an existing parcel locker network or consumer base when studying network design and adoption. This study highlights the importance of tailoring information to consumer characteristics, emphasizing network features that best align with potential parcel locker users. Specifically, we found gender and regulatory focus to influence consumer reaction to information disclosure, where loss-framed information is the most influential particularly for promotion-focus individuals.

Near the end of his life, the eminent literary critic Edmund Wilson was editing his notebooks from the Twenties for publication. At one point he added a long passage on Elinor Wylie, a close friend and successful writer whose work he admired:

The design of bibliographic records for computer input is explored. The elements of a record provide bibliographic description, serve as retrieval keys, facilitate ordered filing, and indicate locations. The effect of each of these functions on the form of the record is discussed. Problems are raised that must be resolved before an optimal record can be designed.

The British Food Journal is in no way concerned with politics, and as it would appear that the propositions put forward by Mr. CHAMBERLAIN are commonly regarded as constituting matter for political controversy instead of being looked upon as subjects for serious investigation and discussion entirely outside the field of politics, it would be an undesirable course and one likely to be misunderstood and, no doubt, misrepresented, were we to refer to the great question which is now before the country without plainly indicating at the outset that we have no intention of supporting or opposing any political party or any section of politicians. We believe Mr. CHAMBERLAIN'S suggestion that the subjects which he has brought forward should be discussed on a higher plane than on the muddy plane of party politics was a reasonable and proper suggestion which all men of sense who are not blinded by political bias should applaud and endeavour to adopt. We do not mean to say that problems of so complicated a character are capable of being accurately solved, in the present state of knowledge, by scientific methods other than actual experiment. They certainly cannot be solved by abstract discussions of a pseudo‐scientific character. The factors which enter into the problems of political economy are so numerous, so complex, and so little understood, that to endeavour to argue even on the basis of what are alleged by political economists to be well‐ascertained facts in the so‐called “dismal science” is to lay oneself open to the charge of theorising from insufficient data. HERBERT SPENCER has lucidly demonstrated the universality of this scientific crime. On comparatively simple subjects, in regard to which a man has no special knowledge, he will, if possessed of the quality known as common sense, generally decline to deliver oracular opinions; but, let a subject be sufficiently complex and let the data relating to it be few, obscure, and uncertain, then decisive opinions will be delivered by all and sundry,—and the more profound the ignorance the more decisive will be the expression of opinion.

In 1912 Sir Frederick Gowland Hopkins reopened the whole question, and investigated again the effects on animals of a synthetic diet. Again he demonstrated the importance of the addition of milk, and in addition he pointed out the importance of the proteins and that some were capable of maintaining life whilst others were inadequate so that animals failed to grow when fed on them. Through this work he systematised previous work and also added an important contribution to our knowledge of nutrition by his discovery of the essential amino acids. These have been extensively studied in recent years, and the following are now regarded as being essential, according to a table by William C. Rose:—

WE seem to be immediately facing a drive for much more technical education and for many more technical colleges and schools to produce it. In the condition of the world today this is an inevitable, an indispensable, process. The reasons are loudly proclaimed and patent to every librarian, and the library must come strongly, as it always has, into the picture but perhaps now more universally and with greater intensity. Dr. Chandler, who is proceeding at a rare pace to specialize his departments, has created a new local council to unify the information work that has already been done at Liverpool. Every technical book costing over five shillings is bought, and the usual collections of periodicals and other material of technical and industrial interest are being increased and a bulletin of additions is being issued soon after the end of each month. The Technical library is one that combines lending and reference activities, telephone and postal services; in fact all the orthodox activities that have been standard in the larger towns since Glasgow began them in 1916, and possibly new and extended ones. The William Brown Library which was destroyed in Air Raids is being reconstructed and the enlarged Technical Library will be developed in it. This is one city only; every large city reports some increase in the services rendered, for example the Telex service is now available at Manchester. It is essential that public libraries everywhere realize the part they may play; if they do not, the suggestion made recently that the lending of technical books should become an activity of the Technical Colleges may become a reality.
