Subjective and Non-subjective Information in Childrenās Allegations of Abuse
In this study, we were interested in how interviewers elicit subjective information in investigations of child abuse (e.g., descriptions of thoughts, emotions, opinions). Sixty-one interviews of children aged 4-12 years old were analyzed to determine the amount of subjective information versus non-subjective event details reported, and the type of question that elicited the information. Interviewers elicited more non-subjective than subjective information, although there was more focus on subjective information in the rapport-building phase than in the substantive phase when the allegations were elicited. Interviewer prompts and child responsiveness was congruent such that non-subjective questions elicited more non-subjective information, and subjective interviewer questions elicited more subjective information. The presence of subjective information in childrenās testimony can influence childrenās credibility, and the results of this study demonstrate that forensic interviewers play a significant part in the level of subjective information children provide
Characterization of the Arsenate Respiratory Reductase from Shewanella sp. Strain ANA-3
Microbial arsenate respiration contributes to the mobilization of arsenic from the solid to the soluble phase in various locales worldwide. To begin to predict the extent to which As(V) respiration impacts arsenic geochemical cycling, we characterized the expression and activity of the Shewanella sp. strain ANA-3 arsenate respiratory reductase (ARR), the key enzyme involved in this metabolism. ARR is expressed at the beginning of the exponential phase and persists throughout the stationary phase, at which point it is released from the cell. In intact cells, the enzyme localizes to the periplasm. To purify ARR, a heterologous expression system was developed in Escherichia coli. ARR requires anaerobic conditions and molybdenum for activity. ARR is a heterodimer of ~131 kDa, composed of one ArrA subunit (~95 kDa) and one ArrB subunit (~27 kDa). For ARR to be functional, the two subunits must be expressed together. Elemental analysis of pure protein indicates that one Mo atom, four S atoms associated with a bis-molybdopterin guanine dinucleotide cofactor, and four to five [4Fe-4S] are present per ARR. ARR has an apparent melting temperature of 41Ā°C, a Km of 5 ĀµM, and a Vmax of 11,111 Āµmol of As(V) reduced minā1 mg of proteinā1 and shows no activity in the presence of alternative electron acceptors such as antimonite, nitrate, selenate, and sulfate. The development of a heterologous overexpression system for ARR will facilitate future structural and/or functional studies of this protein family
The Creative Job Pursuit: The Ability to Follow Oneās Dream Fearlessly
The Creative Job Pursuit: The Ability to Follow Oneās Dream Fearlessly. This project contains a resource guide that will assist students applying and exploring for jobs. The project also shows how divergent and convergent tools can aid in this experience and includes information on divergent and convergent tools such as Pluses, Potentials, Concerns, and How to overcome those concerns (PPCo), Brainstorming, and Storyboarding. These tools were needed in order to develop the risk-taking skill that was pertinent to this project. The tools and skill applied in this project allowed for the search for an ideal job that fosters and nurtures creativity and its many facets. The project report incorporates my own personal job seeking stories for inspiration and strength for others

Infancy and beyond: Parents supporting the healthy sexual and emotional development of their children
The purpose of this project is to bring parental awareness to the subject matter, expand their knowledge base, and increase the parenting skill set related to childhood sexual development. The goal of this project is to shed light on childhood sexual development in service of best practice parenting, ultimately leading to optimal child outcomes. Providing parents with the knowledge to foster the healthy sexual development of their children is the ultimate goal. The participants were recruited from the California State University, San Bernardino (CSUSB) student body and were asked to fill out a demographic questionnaire
Russian foreign trade, 1680-1780: the British contribution
This study aims to establish the development of foreign trade in the Muscovite
lands, the Baltic provinces and in the areas which were newly settled in the mid
eighteenth century with particular reference to the role of British merchants in
these changes. This has required an analysis of the structure of trade through
the 'Russian' Baltic and White Sea ports and an investigation of the changing
patterns of commercial acitivity caused by fluctuations in the boundaries of
their supply areas and of internal and external markets for the goods they
handled. Detailed consideration has been given to the commodities handled in
the import, export and re-export trades utilising data from the Sound Toll
accounts together with British and Russian customs statistics.
Having established a wide framework for the investigation of Russian foreign
trade, detailed consideration has been given to the role of the British
commercial community. In order to do so it has been necessary to reconstruct
the methods used by British merchants in Russia in organising their commercial
activities: this includes examining the structure of the British mercantile
'houses' in all the Russian ports, but especially in St. Petersburg; the patterns of
recruitment of young men into the trade and their style of life in Russia; the
network of contacts which they established among their compatriots, whether
involved in commerce or other professions, with other foreign merchants and
also with their aristocratic clients and their Russian counterparts involved in
internal trade. Merchants in the Russia trade faced changing costs to their
business for freight, insurance and customs duties and the fluctuations in these
charges and their responses to them have been assessed. One of the most
important aspects of their activities was the way in which they financed their
trade. Decision-making in this matter was influenced by events throughout
Europe as well as in Russia, for account had to be taken of the relative value in
silver of the commodities which the Russia merchant handled in that country and
elsewhere. Thus, during the late seventeenth century, they paid for Russian
goods in specie whilst increasingly in the eighteenth century it made better
economic sense to deal in imported commodities as far as the market allowed
and finance the balance with trade surpluses accumulated elsewhere, thereby
causing the emergence of a close co-operation between the British and Dutch
communities in Russia in financing their trade, with the Dutch lending the
proceeds of their import surplus to the British in return for bills of exchange on
Amsterdam. The costs arising from the movement of the rate of exchange and
interest rates within the financial network so formed, have been fully invesĀ¬
tigated and their effect on the trade explored.
The effects of these changes on Russia's overseas trade and the internal impact
of the development of this external commercial sector to the Russian economy
receives especial consideration with particular emphasis being placed on the
response of the aristocracy in both their changing patterns of consumption of
imported goods and in the development of their estates to provide raw materials
for export or supplying Russian merchant and serf manufacturers who were at
this time responding to growing overseas markets for their products

Value Added Methods: Moving from Univariate to Multivariate Criteria
The authors describe five value-added methods (VAM) used in school assessment as the backdrop to their main thesis. Then they review the assumptions underlying measurement and evaluation, the foundation of all assessment systems, including value-added. They discuss the traditional criterion variable used in VAM: a standardized test score. Next, they challenge the univariate assumptions of VAMs, and argue that a multivariate paradigm of VAM is more advantageous for educators and stakeholders. Finally they describe a potential scenario whereby a multivariate VAM might be implemented
