    "abstract": "Previous approaches to the photo- and electro-production of strangeness off\nthe proton, based upon effective hadronic Lagrangians, are extended here to\nincorporate the so called off-shell effects inherent to the fermions with spin\n\u003e= 3/2. A formalism for intermediate-state, spin 3/2, nucleonic and hyperonic\nresonances is presented and applied to the processes $\\gamma + p ---\u003e K^{+} +\n\\Lambda$, for $E_{\\gamma}^{lab}$ \u003c= 2.5 GeV, $e + p ---\u003e e\u0027 + K^+ + \\Lambda$,\nas well as the branching ratio for the crossed channel reaction $K^- + p ---\u003e\n\\gamma + \\Lambda$, with stopped kaons. The sensitivity, from moderate to\nsignificant, of various observables to such effects are discussed.",
