Ezi ziphumo zibonisa njani izithethe kunye noxanduva elichazayo unokuyilawula ukusebenza ungenelelo proenvironmental. "

    Funda iphepha zabo kwaye uyile phindana yokufunda 1.

  9. [ phakathi , nokuqokelelwa kwedatha ] Ukwakha phezu kumbuzo ongasentla, ngoku ukwenza uyilo lwakho.

    1. musa thelekisa njani imiphumo?
    2. Yintoni eyayibangela ezi umahluko?
  10. [ phakathi ] Kukhe kwakho ingxoxo enkulu mayela esebenzisa nxaxheba baqeshwa Amazon Mechanical Bonk. Ngaxeshanye, kuthe kwakhona ingxoxo enkulu mayela esebenzisa nxaxheba zifunwa kuluntu umfundi isidanga. Bhala memo enamaphepha-ezimbini ngokuthelekisa ethelekisa Turkers kunye undergraduates njengoko abaphandi nxaxheba. uthelekiso wakho kufuneka zibandakanye ingxoxo zombini imiba yenzululwazi amalungiselelo.

  11. [ lula Incwadi] Jim Manzi xa ungalawulwa (2012) kukwazisa emangalisayo kungena amandla nokulinga kwishishini. Kwincwadi yena ayidlulisele eli bali:

    "Ndandike kwintlanganiso kunye yingqondi ishishini oyinyaniso, noziqulathe-ezenziwe Billionaire owaba anzongonzongo, understating ongenantandabuzo kwamandla imifuniselo. inkampani yakhe wachitha imithombo ebalulekileyo ezama ukwenza imiboniso kwivenkile window kakhulu ukuba uza kutsala abathengi kunye nokunyuka kwiintengiso, njengobulumko eqhelekileyo bathi kufuneka. Iingcali kuvavanywa ngononophelo uyilo emva uyilo, kwaye iiseshoni zokuhlolwa uvavanyo ngamnye kwisithuba seminyaka waqhubeka ababonakalisi nefuthe nakuyo loyilo omtsha umboniso ngamnye kwiintengiso. Senior intengiso yempahla abalawuli wadibana ne-CEO ukuphonononga la iziphumo zovavanyo zezembali Toto. Emva ebonisa zonke iinkcukacha zonyango, baqonda ukuba ubulumko eqhelekileyo yaba imiboniso engalunganga-ukuba window kwiintengiso musa ukuqhuba. amanyathelo kwabo kucetyiswa ukunciphisa iindleko kunye neenzame kule ndawo. Oku kakhulu wabonisa amandla ukulinga ukuze sibhukuqe ubulumko eziqhelekileyo. impendulo CEO iye elula: aqukumbela wam kukuba abayili zenu kakuhle kakhulu. ' Isisombululo sakhe ukwandisa iinzame kuyilo kwivenkile umboniso, yaye ukuba abantu abatsha ukuyenza loo nto. " (Manzi 2012, 158–9)

    Sesiphi uhlobo ngokusemthethweni na eziphathelelene CEO?

  12. [ lula ] Ukwakha phezu kumbuzo ongasentla, cinga ukuba nawe entlanganisweni apho iziphumo yemifuniselo kwaxoxwa. Yiyiphi imibuzo emine ucela, enye uhlobo ngalunye semthethweni (manani, ukwakha, ngaphakathi, nangaphandle)?

  13. [ lula ] Bernedo, Ferraro, and Price (2014) ufunda isiphumo kunyaka-ezisixhenxe ungenelelo zokonga amanzi ochazwe Ferraro, Miranda, and Price (2011) (khangela Umfanekiso 4.10). Kweli phepha, Bernedo noogxa kwakhona kufuna ukuqonda indlela emva isiphumo ngokuthelekisa ngehambo lamakhaya yaye ziye ningashukunyiswa emva konyango owanikelwa. Oko kukuthi, kalukhuni, bazama ukubona ukuba ngaba unyango nefuthe ikhaya okanye yezindlu.

    1. Funda iphepha, chaza uyilo babo, zishwankathela iziphumo zabo. b) Ingaba iziphumo zabo nefuthe indlela ofanele ukuhlola iindleko-esebenzayo yokungenelela efanayo? Ukuba kunjalo, kutheni? Ukuba akunjalo, kutheni?
  14. [ lula ] Xa olulandelayo ukuya Schultz et al. (2007) , Schultz kunye nabalingane enze uthotho experimenti ezintathu nefuthe kwezithethe echazayo injunctive kwi ukuziphatha eyahlukileyo yokusingqongileyo (itawuli kwakhona) kwiimeko ezimbini (ehotele kunye Condominium Timeshare) (Schultz, Khazian, and Zaleski 2008) .

    1. Shwankathela uyilo kunye iziphumo zezi mvavanyo ezintathu.
    2. Hayi, ukuba ngamaxesha onke, bona ukutshintsha ukutyhilwa yakho Schultz et al. (2007) ?
  15. [ lula ] Ukuphendula Schultz et al. (2007) , Canfield, Bruin, and Wong-Parodi (2016) wabaleka uthotho lab-ezifana imifuniselo ukufunda nokuyilwa iindleko zombane. Nantsi indlela zichaza bokoqobo:

    "Xa lamava uphando-based, nxaxheba ngamnye wabona ityala lombane uqikelelo intsapho kunye nokusetyenziswa kakhulu kangako umbane, yokugubungela iinkcukacha malunga (a) ukusetyenziswa imbali, (b) uthelekiso kubamelwane, kunye (c) Ukusetyenziswa zembali kunye sombane yokuwa. Nxaxheba babona zonke iintlobo ulwazi enye ezintathu yeefomati kubandakanya (a) iitafile, (b) iigrafu bar, kunye (c) iigrafu icon. Senza ingxelo ngeziphumo eziphambili ezintathu. Okokuqala, abathengi kakuhle uhlobo ngalunye ulwazi umbane-ukusebenzisa eyona xa lwanikelwa itafile, iitafile mhlawumbi kuba lula ukufunda ingongoma elula. Okwesibini, ulwazi kunye neenjongo ukugcina umbane le ngamandla ukuba inkcazelo ukusetyenziswa imbali, elizimeleyo ifomathi. Okwesithathu, abantu kunye nokubhala amandla aphantsi kakuhle zonke iinkcukacha ngaphantsi. "

    Ngokungafaniyo nezinye izifundo alandele-up, isiphumo eziphambili umdla Canfield, Bruin, and Wong-Parodi (2016) ingxelo ukuziphatha hayi indlela yokuziphatha. Ngawaphi amandla kunye nobuthathaka olu hlobo yokufunda kwinkqubo yophando ebanzi ekukhuthazeni ukonga umbane?

  16. [ phakathi , endiythanda kakhulu ] Smith and Pell (2003) kukho satirical meta-Uhlalutyo lwamaphononongo ebonisa ukusebenza parachutes. Bagqiba:

    "Njengokuba ngoncedo ezininzi yenzelwe ukuthintela impilo enkenenkene, ukusebenza parachutes khange phantsi novavanyo ngamandla ngokusebenzisa iimvavanyo alawulwayo. Ukulwela amayeza ezisekelwe kubungqina wayenokubagxeka ukwamkelwa zokungenelela zavavanywa ngokusebenzisa data kuphela lokuqwalasela. Sicinga ukuba wonke kungakuhle ukuba abo baphambili ezininzi ngokugqibeleleyo wamayeza esekelwe kubungqina ziwuququzelele bathatha inxaxheba iimfama kabini, olungenamkhethe, placebo, crossover ukuqotywa iparashute. "

    Bhala op-ed efanelekileyo iphephandaba ukufunda ngokubanzi, njenge The New York Times, uphikisana fetishization ubungqina uvavanyo. Nika imizekelo, eziphathekayo. Icebiso: Bona, Bothwell et al. (2016) kunye Deaton (2010)

  17. [ phakathi , kufuna nokhowudo , endiythanda kakhulu ] Umahluko-in-iiyantlukwano estimators ye nempembelelo unyango achaneke ngaphezu umahluko-in-kuthetha estimators. Bhala yimemo eya njengoononjineli ophethe uvavanyo A / B kwinkampani eendaba zentlalo start-up echaza ixabiso umahluko-in-iiyantlukwano indlela yokubaleka ulingelo online. Yimemo kufuneka ibandakanye ingxelo ingxaki, ezinye i ncebiso malunga iimeko apho umahluko-in-umahluko Estimator uya eyi umahluko-in-kuthetha Estimator, kwaye isifundo yokulinganisa elula.

  18. [ lula , endiythanda kakhulu ] UGary Loveman yaba unjingalwazi School Business eHarvard phambi kokuba CEO Harrah, omnye iinkampani yekhasino inkulu ehlabathini. Xa wafudukela Harrah ngayo, Loveman baguqula lenkampani kunye nenkqubo rhoqo ukunyaniseka ukubhabha-njalo wawenza obungummangaliso data malunga nokuziphatha abathengi. Encotsheni yale nkqubo womlinganiselo usoloko-kwi, inkampani waqala experiments ibaleka. Umzekelo, ukuba agidime umfuniselo ukuvavanya ifuthe iphecana kwihotele busuku kubathengi kunye ipateni yokungcakaza ethile. Nantsi indlela Loveman wachaza ukubaluleka nokulinga kwizenzo ngemihla yoshishino Harrah esithi:

    "Oku ngathi awufuni abaxhaphaza abafazi, nina musani ungebi, yaye umelwe ukuba neqela lolawulo. Le yenye yezinto ungaphulukana umsebenzi wakho kuba Harrah's-awusebenzisi iqela lolawulo. " (Manzi 2012, 146)

    Bhala i-imeyile unguMqeshwa omtsha echaza ukuba kutheni Loveman ucinga ukuba kubalulekile ukuba iqela lolawulo. Kufuneka uzame ukubandakanya umzekelo-nokuba zeziyinyani okanye yenziwe-ukucacisa ingongoma yakho.

  19. [ lukhuni , kufuna zezibalo ] Into entsha ijolise ukuqikelela isiphumo lokufumana izikhumbuzo umyalezo nokubhaliweyo ugonyo ndodla. kwiikliniki 150, nganye 600 ezigulane abafanelekileyo, bakulungele ukuthatha inxaxheba. Kukho kwindleko ezinzileyo zeerandi 100 kwiklinikhi nganye ufuna ukusebenza, kwaye iindleko 1 dollar ngomyalezo ngamnye yokubhaliweyo ofuna ukuthumela. Ngaphezu koko, na iiklinikhi ukuba ukusebenza uya umlinganiselo isiphumo (ukuba ngaba umntu ufumene ugonyo) simahla. Sicinge ukuba uhlahlo lwabiwo-mali 1000 eerandi.

    1. Kuphantsi kwaziphi iimeko kunokuba bhetele ukuba ingqwalasela kwizibonelelo zakho inani elincinane neekliniki kwaye phantsi kweziphi iimeko ukuze kube ngcono ndibaphangalalisele ngaphezulu ngokubanzi?

Xa uthelekisa amanqaku uviwo lokugqibela labafundi abafumene ibar yenkqubela abo bangazange, ufumana, kuninzi Wothuka wakho, ukuba abafundi abangazange bafumane bar nkqubela amanqaku aphezulu. Ngaba oku kuthetha ukuba bar inkqubela yabangela abafundi ukuba bafunde ngaphantsi? Yintoni esinokuyifunda koku data umphumo? (Icebiso: Jonga Gerber and Green (2012) , Isahluko 7.)
  21. [ kakhulu kakhulu , kufuna nokhowudo ] Kwiphepha ezithandekayo, Lewis and Rao (2015) Ngokomzekelo ngokucacileyo umda esisiseko zobalo experimenti nokuba oxandileyo. Eli phepha-leyo soqobo ibinaso isihloko inkanuko "On Near-nakwenzeka Ukubala uphindela Advertising" -shows kunzima kangakanani na umlinganiselo imbuyekezo kutyalo iintengiso intanethi, nokuba experiment digital ebandakanya izigidi abathengi. Okuninzi ngokubanzi, iphepha ubonisa ngokucacileyo ukuba kunzima ukuqikelela isiphumo amancinci unyango phakathi data isiphumo ingxolo. Okanye kuchazwe diffently, iphepha kubonisa ukuba iziphumo zonyango uqikelelo kuya kuba nokuthembeka ezinkulu xa ifuthe-to-eqhelekileyo unxaxho (\ (\ frac {\ bar Delta \ {y}} {\ kw} \)) ratio incinci. Isifundo esibalulekileyo ngokubanzi kweli phepha kukuba iziphumo niselo ngencinane impembelelo-to-eqhelekileyo unxaxho Umlinganiselo (umzekelo, lweROI amaphulo ad) iya kuba nelisi. Umngeni uya kuba ukubhala yimemo eya umntu kwisebe le ntengiso inkampani yakho evaluting kwelinge wayecebe umlinganiselo lweROI ye liphulo ad. iimemo wakho kufuneka zixhaswe iigrafu ngeziphumo ukulinganisa computer.

    Nazi ezinye iinkcukacha siqalo onokuzifuna. Zonke ezi amaxabiso lwamanani bayafana yemifuniselo zokwenyani ingxelo Lewis and Rao (2015) :

    • LweROI, i obala engundoqo amaphulo ad intanethi, ichazwa ukuba ingeniso umnatha ukusuka iphulo (ingeniso epheleleyo esuka iindleko iphulo uthabatha yephulo) lahlulwe iindleko phulo. Umzekelo nephulo yayingabancedi kwiintengiso wayeza kuba lweROI ye -100% kunye nephulo apho inzuzo wayelingana iindleko wayeza kuba lweROI 0.

    • ekuthengiswa mean umthengi ngamnye $ 7 kunye nokungafani komgangatho $ 75.

    • iphulo kulindeleke ukuba ukwandisa Uk nge $ 0,35 ngumthengi ngalinye kufanekisela ukwanda kwingenelo $ 0,175 abathengi nganye. Ngamanye amazwi, le lomda yi-50%.

    • ubungakanani ecwangcisiweyo kwalingwa ngabantu 200,000, isiqingatha kwiqela lonyango kunye nesiqingatha kwiqela ulawulo.

    • iindleko phulo $ 0,14 nxaxheba ngamnye.

    Bhala memo evaluting olu vavanyo. Ungacebisa ndimisele le ukucikideka njengoko bekucetyiwe? Ukuba kunjalo, kutheni? Ukuba akunjalo, ucebisa ukuba utshintsho?

  24. [ kakhulu kakhulu , kufuna zezibalo , kufuna nokhowudo ] Cinga ukuba ezibhaliweyo yimemo ichazwe ngentla-ngokusebenzisa yokulinganisa, iziphumo abahlalutyayo, okanye zombini-yaye umntu kwisebe sentengiso incomela ukuba usebenzisa umahluko-in-iiyantlukwano Estimator kunokuba umahluko kwindlela Estimator (jonga kwiCandelo 4.6.2) . Bhala memo entsha elifutshane echaza indlela 0.4 unxulumano phakathi kwiintengiso phambi kwalingwa nentengiso emva ukucikideka uza ukutshintsha isigqibo sakho.

  25. [ lukhuni , kufuna zezibalo ] Ukuze ukuvavanya ukusebenza kwenkonzo entsha amakhondo web-based, i-ofisi iinkonzo omsebenzi eyunivesithi yenze lwalawula ngokungenamkhethe phakathi kwabafundi 10,000 abangena unyaka wabo wokugqibela esikolweni. A yorhumo ivideo ulwazi log-in eyodwa wathunyelwa ngokusebenzisa isimemo email awodwa 5000 abafundi randomly ekhethiweyo, ngoxa omnye 5,000 abafundi kwiqela lolawulo kwaye musa ukuba ubulungu. kwiinyanga ezilishumi elinesibini emva koko, uphando follow-up (ngaphandle non-impendulo) ibonisa ukuba zombini unyango kunye nolawulo amaqela; 70% abafundi abaye yafumana zengqesho yexesha elizeleyo entsimini yabo abanyulwa (Itheyibhile 4.5). Ngoko, kubonakala ukuba inkonzo web-based nafuthe.

    Nangona kunjalo, olukhaliphileyo Isazinzulu data kwiyunivesithi wajonga idata kancinane ngokusondeleyo ngakumbi wafumana ukuba-20% kuphela abafundi kwiqela kunyango wakha ayilogwanga kwi-akhawunti emva kokufumana email. Ngaphezu koko, elifuna Akumangalisi, phakathi kwabo baye loganga kwi website-60% kuphela Ndafumana umsebenzi wexesha elizeleyo entsimini yabo abanyulwa, leyo ngaphantsi umlinganiselo abantu abazange ungena kwaye ngaphantsi umlinganiselo abantu imeko yolawulo (Itheyibhile 4.6).

    1. Nika ingcaciso oko bekunokwenzeka.
    2. Zeziphi iindlela ezahlukileyo ezimbini ukubala iziphumo zonyango kweli ukucikideka?
    3. Njengoko esi siphumo, kufuneka inkonzo amakhondo eyunivesithi kubonelela ngale nkonzo amakhondo web-based kubo bonke abafundi? Nje ukuba gca, oku umbuzo impendulo elula.
    4. Yintoni ekufuneka beyenzile?

    Icebiso: Lo mbuzo uya ngaphaya kumbandela kwesi sahluko, kodwa ikwaqwalasela nemiba eqhelekileyo imifuniselo. Olu hlobo kuyilo lokuvavanywa wambi ebizwa ngokuba kuyilo ukhuthazo kuba bayakhuthazwa nxaxheba ukuba nenxaxheba kulo unyango.
