Drought
nowadays ancient practices part relegated folklore replaced rational water management.types people tend define droughts three main waysmeteorological drought occurs prolonged time less average precipitation.meteorological drought usually precedes kinds drought.agricultural droughts affect crop production ecology range.condition also arise independently change precipitation levels either increased irrigation soil conditions erosion triggered poorly planned agricultural endeavors cause shortfall water available crops.however traditional drought caused extended period average precipitation.hydrological drought brought water reserves available sources aquifers lakes reservoirs fall locally significant threshold.
Drought
hydrological drought tends show slowly involves stored water used replenished.like agricultural drought triggered loss rainfall.instance around kazakhstan awarded large amount money world bank restore water diverted nations aral sea soviet rule.similar circumstances also place largest lake balkhash risk completely drying out.as drought persists conditions surrounding gradually worsen impact local population gradually increases.causes precipitation deficiency mechanisms producing precipitation include convective stratiform orographic rainfall.
Drought
convective processes involve strong vertical motions cause overturning atmosphere location within hour cause heavy precipitation stratiform processes involve weaker upward motions less intense precipitation longer duration.precipitation divided three categories based whether falls liquid water liquid water freezes contact surface ice.droughts occur mainly areas normal levels rainfall low.factors support precipitation volumes sufficiently reach surface sufficient time result drought.drought triggered high level reflected sunlight average prevalence high pressure systems winds carrying continental rather oceanic air masses ridges high pressure areas aloft prevent restrict developing thunderstorm activity rainfall one certain region.
Drought

boundary coordination individuals private information protected individuals boundaries.permeability boundaries everchanging allow certain parts public access certain pieces information belonging individual.sharing private information risky decision puts owner information vulnerable position.therefore rules surrounding boundaries must negotiated protect shared information.private information shared coowners must coordinate boundaries privacy disclosure based boundary permeability boundary linkage boundary ownership.

petronio describes mutual boundary coordination coowners drawing borders map around shared piece information.means easy process considering owner approach information distinct viewpoints referencing personal criteria privacy rule development.boundary permeability refers nature invisible divisions keep private information known outside individual particular group.private information kept one owner boundaries said thick less possibility information make way public sphere.information shared one persons boundaries private information expand become permeable considered thin.boundary linkage owners connected build associations boundary.

example doctors patients linked way private information passed within boundaries constantly.linkages strong weak depending information shared whether coowner wanted know prepared learn new piece information.case point link organization spy meant infiltrate organization weak two coordinated information maintained private disclosed.boundary ownership refers responsibilities rights person control spread information own.working mutually create boundary privacy key parties clear understanding whether information shared shared shared.simple example planning surprise birthday party involved planning must agree information party spread ruin surprise.

disclosure new party intent happens coowners feel expectations maintaining boundaries violated.in addition boundary turbulence occurs coowner intentionally breaks coordinated boundary privacy disclose private information.example intentional disclosure would daughter revealing doctor father indeed active smoker father told doctor longer smokes heart surgery.daughter case must weigh risks breaking family privacy boundary benefits doctor better informed fathers condition.lastly boundary turbulence also occur preexisting rules situation.example emergence social media particular facebook boundary rules established.parents began join facebook friend children children felt turbulence.

perception privacy invasion parentchild relationship.in cases boundary turbulence coowners information feel expectations violated lose trust coowners.cases goal party reduce turbulence reestablishing coordinating boundaries.turbulence doesnt always negative outcome studies show turbulence within relationships lead stronger improved relationships.boundary violations boundary turbulence used learning opportunity individuals renegotiate existing boundaries better form new boundaries similar situations.boundary turbulence experienced differently individual reactions violations depend many new boundary linkages created many new people private information reaches.

factors determine whether boundary turbulence cause distress relationship learning experience.control ownership communication privacy management theory understands information well boundaries something owned owner must decide whether willing confidant i.e.coowner malparida piroba information.cases preferable owner another person share private information though may case confidant.coownership information characterized two things heavy responsibility knowledge rules particular disclosure.

however ownership felt different degrees understanding disclosure rules different owner owner.also act sharing coupled along realization boundaries expanded may never return original state.responsibility coowners decide make clear information shared others.rulebased management system petronio views boundary management rule based process individual decision.rulebased management system allows management individual collective levels.
