Problem Method of Teaching Home Economics

In our public schools to day, we find students coming to us in our Home Economics work with varying degrees of theoretical as well as actual home experience and training. Most of our school systems have no way of sectioning this group according to ability and training of the students because the entire group ·must be placed in one class and requested to do the same work. On account of this grouping we find often a lack of initiative, of interest, and especially a strong feeling of lack of progress

School lunch Room an Education in Food Selection

Feeling a decided need for the furthering of the plan to establish the correct food habits in youngsters who were old enough to attend school, a lunch room was planned. This lunch room, operating only at noon time is one which has not only helped the child in the right selection of foods, at a given meal, but has established in the mind of the child certain definite food habits which can only lead to a more normal child life, the aim of every child institution

The American Housewife in the Philippines

The American viewpoint of a foreign country is probably far different from that of the American who spends his life among them, said Mrs. Jean Walser, Associate Professor in Mathematics at the University of the Philippines at Manilla, who has just returned from the Philippines to the Iowa State College campus. People living far across the water from a country of which they know little about the actual life there, wonder at the strangeness of the foreigners who find their way to our shores. Maybe the Americans who journey to the Philippines are just as much a source of curiosity to the natives with their strange dress, short hair, and peculiar American habits and customs

Perceptions Of The Library: A Key To Planning Effective Services

such as questions answered, books cataloged, and dollars spent. Now we are called upon to measure the impact of those services on our clients. Stakeholder demand for accountability, changing accreditation standards, and state and federal concerns over student outcomes have driven a real concern for measurement from the client’s perspective. This will become increasingly important as demands for accountability and competition from other sectors increase. “Assessment and evaluation are intended as means to demonstrate institutional effectiveness, foster institutional improvement, and demonstrate accountability.” Programs such as the New Measures Initiative, from the Association of Research Libraries, have been developed to strengthen the role of the library vis-à-vis learning and research. This program was created to respond to increasing demand for outcomes measurement and increasing pressure to maximize use of resources. It is designed to help investigate strategies for assessing the library\u27s value and exploring the library\u27s impact on learning, teaching, and research

Carboxylation and Decarboxylation of Aluminum Oxide Nanoparticles Using Bifunctional Carboxylic Acids and Octylamine

The carboxylation of alumina nanoparticles (NPs), with bifunctional carboxylic acids, provides molecular anchors that are used for building more complexed structures via either physisorption or chemisorption. Colloidal suspensions of the NPs may be prepared by covalently bonding a series of carboxylic acids with secondary functional groups (HO2C-R-X) to the surface of the NPs: lysine (X = NH2), p-hydroxybenzoic acid (X = OH), fumaric acid (X = CO2H), and 4-formylbenzoic acid (X = C(O)H). Subsequent reaction with octylamine at either 25°C or 70°C was investigated. Fourier transform IR-attenuated reflectance spectroscopy (FTIR-ATR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) along with energy dispersive X-ray (EDX) analysis were used to characterize the bifunctionalized monolayers and/or multilayer corona surrounding the alumina NPs and investigate the reaction mechanism of octylamine with the functional groups (X) of the NPs. Except for the fumaric functionalized NPs, addition of octylamine to the functionalized NPs leads to removal of excess carboxylic acid corona from the surface via an amide formation. The extent of the multilayer is dependent on the strength of the acid⋯acid interaction

Task-phase-specific dynamics of basal forebrain neuronal ensembles.

Cortically projecting basal forebrain neurons play a critical role in learning and attention, and their degeneration accompanies age-related impairments in cognition. Despite the impressive anatomical and cell-type complexity of this system, currently available data suggest that basal forebrain neurons lack complexity in their response fields, with activity primarily reflecting only macro-level brain states such as sleep and wake, onset of relevant stimuli and/or reward obtainment. The current study examined the spiking activity of basal forebrain neuron populations across multiple phases of a selective attention task, addressing, in particular, the issue of complexity in ensemble firing patterns across time. Clustering techniques applied to the full population revealed a large number of distinct categories of task-phase-specific activity patterns. Unique population firing-rate vectors defined each task phase and most categories of task-phase-specific firing had counterparts with opposing firing patterns. An analogous set of task-phase-specific firing patterns was also observed in a population of posterior parietal cortex neurons. Thus, consistent with the known anatomical complexity, basal forebrain population dynamics are capable of differentially modulating their cortical targets according to the unique sets of environmental stimuli, motor requirements, and cognitive processes associated with different task phases
