Rotation-electronic interaction in the 3p-complex Rydberg state of water

An energy theory is formulated for the rotational energy levels in a p-complex Rydberg state of an asymmetric top molecule of symmetry C2v. The effective Hamiltonian used consists of the usual rigid rotor Hamiltonian augmented with terms representing electronic spin and orbital angular momentum effects. Criteria for assigning symmetry species to the rotational energy levels, following Houganfs scheme that uses the full molecular group,are established and given in the form of a table. This is particularly suitable when eigenvectors are calculated on a digital computer. Also, an intensity theory for transitions to the Rydberg p-complex singlet states is presented and selection rules in terms of symmetry species of energy states are established. Finally, applications to HpO and DpO are given.

"Welcome to my life" : the experiences of single mothers who are the recipients of multiple state provided benefits

Abstract This research takes the lens of social reproduction as a starting point for an examination of the effects of recent social welfare reforms on the lives o.fsingle mothers. As the cumulative effects o.f diminishing state provided benefits take hold, tensions are heightened as single mothers internalize the insecurity of earning an income in 11 capitalist labour market, while trying to carry out all that is involved in social reproduction with inadequate means of survival. Through interviewing single mothers who are the recipients of mUltiple state provided benefits (social assistance, student loans, subsidized housing and subsidized childcare), this thesis illuminates the cOl1linued regulation of women in an effort to assure that social reproduction is occurring at the lowest cost possible. State provided benefits are set lip in such a way that it is near impossible for single mothers to make ends meet without entering the labour force or entering into co-residential relationships. This push towards the labour force and/or marriage via punitive welfare policies illuminates the devaluation of the labour that is done at home. Through interviewing 5 single mothers, I will demonstrate the extensive labour that goes into maintaining their households. In addition .J case managers are interviewed. The employees of social assistance, subsidized hOllsing, subsidized childcare and student loans, have much agency in deeming who is worthy of receiving benefits. The employees of these agencies have the ability to make these women's lives easier or more complicated by how the workers interpret the policy regulations. Social policies are of paramount importance in the quest for women's equality and thus have consequences for how women's daily lives are organized. The rules and regulations that govern the individual policies are complex and bureaucratic and have implications for the ways in which women must organize their lives in order to survive. The shifts in social policy have been guided by neo-liberal assumptions with a focus on individual responsibility and a market-modeled welfare state. The caring work that is involved in raising children to be productive in a capitalist society is ignored or devalued in current policies. The emphasis in each polic.:v is on getting women who receive benefits into the paid work force, with little facilitation or investment into the caring work these women do on a daily basis that in turn supports capitalism. Policies, such as social assistance, subsidized housing, subsidized childcare and student loans, are set up in such a way that ignores the reality of women's day-to-day lives and devalues the necessary work done at home. It takes an abundance of labour and strategizing for women to seek out necessary means of survival, labour that is amplified when a woman is dealing with mUltiple slate provided benefits.

Task-Dependent Oscillatory Brain Activity During Oculomotor Delayed Response Task

This study used three Oculomotor Delayed Response (ODR) tasks to investigate the unique cognitive demands during the delay period. Changes in alpha power were used to index cognitive efforts during the delay period. Continuous EEGs from 25 healthy young adults (18-34 years) were recorded using dense electrode array. The data was analyzed by 6-cycle Morlet wavelet decompositions in the frequency range of 2-30 Hz to create time- frequency decompositions for four midline electrode sites. The 99% confidence intervals using the bootstrapped 20% trimmed mean of the 10 Hz frequency were used to examine the differences among conditions. Compared to two Memory conditions (Match and Non-Match), Control condition yielded significant differences in all frequencies over the entire trial period, suggesting a cognitive state difference. Compared to Match condition, the Non–Match condition had lower alpha activity during the delay period at each midline electrode site reflecting the higher cognitive effort required.
