    Abstract
    In this issue Ford, Miller and Moss utilize 68 volunteers from a population of 250 Master's students to complete on the web three search tasks with clear fact based goals and three or less facets. One task required broadening the search concepts from those given, a second provided a specific terminology for one facet but required a second facet that would require translation, and the third required general to specific transformation. The students were measured as to their performance on Entewistle's Revised Inventory of Approaches to Studying providing values for ten study variables and asked to assess their experience on the Internet, with Alta Vista, and with Boolean search. Searches were conducted on Alta Vista using Netscape Navigator 4 with participants free to choose and switch Boolean, best match or combined search modes at will while a front end script recorded all submitted searches and help access. Search related variables extracted were from Boolean only queries, best match only queries, and combined queries. Factor analyses were conducted on all variables for each search mode for each search. In task one Boolean is differentiated from best match search by sharing high loads on active interest, intention to reproduce, fear of failure, and relating ideas. The combined searcher is linked with the best match searcher with low active interest, low intention to reproduce and low fear of failure. In task 2 Boolean is differentiated from best match search by sharing high loads on intention to reproduce and low on intention to understand. Best match loads positively with intention to understand and negatively with intention to reproduce. Combined searching linked with both good and with poor time management. In task 3 the loads mimic task 1. It seems Boolean is consistently linked to a reproductive rather than a meaning seeking approach, but also with high levels of interest and fear of failure. Best match associates with the converse of these measures.

    "Yahoo will künftig mit dem Erzrivalen Google im Bereich Online-Werbung zusammenarbeiten. Zugleich erklärte der Internet-Konzern die Gespräche mit Microsoft über eine vollständige oder zumindest teilweise Übernahme durch den Softwareriesen für endgültig beendet. Konzernchef Jerry Yang sagte am Donnerstag, er sei der Auffassung, dass sich die Partnerschaft mit Google schneller auszahlen werde als ein Geschäft mit Microsoft. Yahoo will Google-Suchanzeigen auf seiner Seite platzieren. Dadurch könnten jährlich 800 Millionen Dollar (rund 517 Millionen Euro) an Umsatz erzielt werden, teilte der Konzern mit. Yang betonte, der Pakt mit Google schließe keine potenzielle künftige Fusion aus, auch nicht mit dem Microsoft. Yahoo konzentriere sich jedoch nun erst einmal auf sein eigenes Geschäft und die Partnerschaft mit Google. Das Abkommen ist zunächst auf vier Jahre angelegt und kann zweimal um je drei Jahre verlängert werden. Die Firmen räumten dem US-Justizministerium freiwillig eine Überprüfungsfrist von dreieinhalb Monaten vor dem Inkrafttreten der Vereinbarung ein. Sie benötigten für das Abkommen jedoch keine Zustimmung von den Kartellbehörden, hieß es in der Yahoo-Erklärung. Microsoft hatte sich seit Monaten um Yahoo bemüht. Der Internetkonzern hatte die Übernahmeofferte von 47,5 Milliarden Dollar aber als zu niedrig abgewiesen. Zuletzt wollte der weltgrößte Softwareproduzent daher immerhin das Yahoo-Suchmaschinengeschäft kaufen, wie zwei in die Angelegenheit eingeweihte Personen am Donnerstag sagten. Konkret habe Microsoft dazu einen 16-Prozent-Anteil an Yahoo erwerben wollen. Yahoo erklärte, dies passe nicht in seine Pläne. Nachdem bekannt wurde, dass die Gespräche zwischen Yahoo und Microsoft platzten, brach die Yahoo-Aktie um zehn Prozent auf 23,52 Dollar ein. Als der Konzern dann aber nach Handelsschluss in New York die Allianz mit Google verkündete, legten die Papiere wieder zu und kosteten nachbörslich 24 Dollar. Unklar war, wie die Entwicklung bei dem Yahoo-Großaktionär Carl Icahn ankam. Der Milliardär hatte mit Unverständnis auf die Ablehnung des Microsoft-Übernahmeangebots reagiert und deshalb das Management scharf angegriffen. Für eine Stellungnahme war er zunächst nicht erreichbar. Marktexperten sagten derweil, sie gingen davon aus, dass es keine weiteren Verhandlungen zwischen Microsoft und Yahoo geben werde. Microsoft werde nun aber versuchen, durch andere Übernahmen sich besser im Suchmaschinen-Wettbewerb gegen Google zu positionieren. Eine Möglichkeit sei der Kauf von AOL. Google ist mit großem Abstand Marktführer. Deshalb dürfte die Partnerschaft mit Yahoo auch auf eine genaue Prüfung durch die Wettbewerbsbehörden stoßen."

    Die Yahoo-Aktien, die bereits am Donnerstag um rund zehn Prozent eingebrochen waren, verbuchten zum Handelsauftakt am Freitag ein weiteres Minus von 3,74 Prozent auf 22,64 Dollar. Microsoft hatte bis zu 33 Dollar je Aktie geboten, Yahoo wollte nach Angaben des Windows-Herstellers mindestens 37 Dollar. Bis zuletzt hatte Großinvestor Carl Icahn vergeblich die Yahoo-Führung unter Druck gesetzt, einer Übernahme durch Microsoft zuzustimmen. Der Milliardär Icahn gehört zweifelsohne zu den Verlierern des Tages. Er ist nach Berechnungen des Wirtschaftsmagazins "Business Week" zu einem durchschnittlichen Aktienpreis von 25 Dollar hei Yahoo eingestiegen und könnte nun statt eines satten Gewinns einen Verlust einfahren. Erst am Montag hatte Yahoo seine Aktionäre in einem Schreiben zur Hauptversammlung uni Unterstützung gebeten. In dem Brief rief das Unternehmen die Anteilseigner dazu auf, den bisherigen Aufsichtsrat wiederzuwählen und damit die von dem als "Firmenjäger" bekannten Icahn aufgestellten Kandidaten abzulehnen. Die Wahl des Aufsichtsrats bei der Hauptversammlung am 1. August sei die entscheidendste für die Aktionäre in der Geschichte des Unternehmens. Das Vorgehen Icahns wird allerdings auch von vielen Analysten unterstützt, die Jerry Yang nicht zutrauen, das Unternehmen aus der Krise zu führen. Es sei unwahrscheinlich, dass das derzeitige Management in der Lage ist, den Wert des Unternehmens auf absehbare Zeit über mehr als 33 Dollar pro Aktie zu bringen, sagte Mark May, Analyst bei Needham & Co. in New York. Am Ende des Machtkampfes zwischen Microsoft und Yahoo sehen etliche Beobachter nur einen Gewinner, nämlich Google. Das Geld im Web wird mit Suchanzeigen verdient. Microsoft wollte unbedingt die Reichweite von Yahoo haben, um zu Google aufzuschließen. Doch letztlich hat Microsoft-Chef Steve Ballmer mit seinem Vorstoß nur erreicht, dass die Online-Anzeigenplätze von Yahoo in den Händen von Google landen werden."
