Theory-based evaluation (TBE) explores the how and why of program success or failure. Advocates of TBE claim that it produces information unavailable in traditional process and outcome studies. This article examines six published papers of TBEs. It finds that the authors of the papers do not always make explicit the relation of their data to the theory of the program. Nevertheless, it was evide...

Data are presented on cathode temperature profiles, electron emission profiles under no-flow conditions, and timed starting tests with gas flow. Correlations between the temporal behavior of the noflow emission current and the starting time are made, and a model is presented of the barium/bariumoxide generation and surface diffusion processes that describe the electron emission profile and star...

Human infections with tick-borne encephalitis (TBE)virus are a public health concern in certain regions of Europe, central and eastern Asia. Expansions of endemic areas and increased incidences have been associated with different factors including ecological changes supporting tick reproduction, socioeconomic changes increasing human outdoor activities and climatic changes favouring virus circu...

TBEV (Flaviviridae, Flavivirus) is an etiologic agent of tick-borne encephalitis (TBE), the most important arboviral human infection involving the central nervous system. The disease is endemic in a zone extending from central and eastern Europe to Siberia and Japan, and corresponds to the distribution of the ixodid ticks, which act both as the vectors and reservoir of TBEV. Humans acquire infe...

Recently, we have found that tbe prostaglandin synthesis inhibitor, indometfaacin, reduced basal and angiotensin stimulated aldosterone release. To further test tbe possibility that prostaglandins (PGs) function as mediators of adrenal steroidogenesis, we examined the release of aldosterone, PGE,, and PGFta under basal and stimulated conditions in isolated adrenal capsular cells in vitro. Angio...

Higb scbool (N = 150) and college (N = 164) students completed a survey of tbeir earliest personal recollection (ER). Tbese memories typically were of events occurring in tbe fourtb year of life, and varied widely in terms of content and associated affect. Tbe ERs of tbe higb scbool sample were dated significantly later, contained more traumatic content, and were more likely to possess tbe qual...

We consider the problems of efficiently diagnosing (and predicting) what did will) happen after a given sequence observations execution partially observable one-clock timed automaton. This is made difficult by facts that automata are infinite-state systems, and they can in general not be determinized. introduce markings as formalism to keep track evolution set reachable configurations over time...

Introduction: The aim of this study was to perform a systematic review and meta-analysis to compare the effect of bone-borne expansion (BBE) and tooth-borne expansion (TBE) in patients with maxillary constriction. Methods: Electronic databases, including MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials, were searched up to February 2019. Elig...

The study of Health in All Policies (HiAP) is gaining momentum. Authors are increasingly turning to wide swathes of political and social theory to frame (Program) Theory Based (or Informed) Evaluation (TBE) approaches. TBE for HiAP is not only prudent, it adds a level of elegance and insight to the research toolbox. However, it is still necessary to organize theoretical thinking appropriately. ...
