方案设计题:社会工作者发现某打工子弟学校的学生存在不同程度的健康问题,其中很多问题与日常生活习惯有关,如果能够做到早发现、早治疗,便可以防止某些疾病的产生。该市早在2009年便颁布了每年为本市中小学生开展体检的政策,但该政策并没有惠及打工子弟学校。社会工作者通过进一步社区走访发现,这些学生大多居住在学校附近的城乡结合部,社区环境卫生很差,垃圾遍地,缺少公共卫生设施,社区周边只有一家正规医院,外来人口很少去。一些家庭没有养成良好的卫生习惯,不少家长也存在不同程度的健康问题,还有部分家庭因为疾病陷入困境。针对上述问题,社会工作者计划在该社区开展社区卫生健康服务项目。要求:分别从“直接介入”和“间接介入”的角度,为该项目设计服务方案,只需说明介入目标和主要介入策略。

Cultural practices, cultural differences, local manners, and mores: traveling the globe can be a behavioral minefield, even when you have the best intentions. Everything from greeting to eating can be an opportunity to do the wrong thing, and not only embarrass yourself, but offend your host countrymen. Look out for the following cultural mistakes and try to avoid them while going abroad.
1.Touching Someone
Where It's Offensive
Korea, Thailand, China, Europe, the Middle East.
What's Offensive
In Mediterranean countries, if you don’t touch someone's arm when talking to them or if you don't greet them with kisses or a warm embrace, you'll be considered cold. But backslapping someone who isn't a family member or a good friend in Korea will make them uncomfortable. In Thailand, the head is considered sacred--never even pat a child on the head.
What You Should Do Instead
Observe what locals are doing and follow suit. In Eastern countries remember that touching and public displays of affection are unacceptable. In places like Qatar and Saudi Arabia, men and women are forbidden from talking, let alone touching.
2.Blowing Your Nose
Where It's Offensive
Japan, China, Saudi Arabia, France
What's Offensive
Some cultures find it disgusting to blow your nose in public--especially at the table. The Japanese and Chinese also dislike it even with a handkerchief.
What You Should Do Instead
If traveling through Eastern and Asian countries, don’t use handkerchief but choose disposable(可溶解的)tissues. In France and in Eastern countries, if you're dining and need to clear your nose, excuse yourself and head to the restroom.
3.Talking Over Dinner
Where It's Offensive
Africa, Japan, Thailand, China, Finland.
What's Offensive
In some countries, like China, Japan, and some African nations, don't start chatting while everyone else is digging into dinner, because mealtimes are for eating, not talking. Also avoid conversations in places a country might consider sacred or reflective---churches in Europe, temples in Thailand, and saunas in Finland.
What You Should Do Instead
Keep quiet!
4.Removing Your Shoes…or Not
Where It's Offensive
Hawaii, the South Pacific, Korea, China, Thailand
What's Offensive
Taking off shoes when arriving at the door of a London dinner party will be regarded as uncivilized, but failing to remove your shoes before entering a home in Asia, Hawaii, or the Pacific Islands will be considered disrespectful.
What You Should Do Instead
If you see a row of shoes at the door, start undoing your laces. If not, keep the shoes on.
5.Knowing Your Right from Your Left
Where It's Offensive
India, Morocco, Africa, the Middle East
What's Offensive
Many cultures still prefer to eat using traditional methods--their hands. In these cases, food is often shared, which is why it's important to wash your hands before eating and observe the right-hand-is-for-eating and the left-hand-is-for-other-duties rule. If you eat with your left hand, expect your fellow diners to be offended.
What You Should Do Instead
Left-handed? Attempt to be ambidextrous --- even children who are left-handed in these cultures are taught to eat with their right hand.
小题1:In which country can you greet someone with a kiss?
A.ThailandB.EnglandC.QatarD.Hawaii
小题2:If you’re in Japan and you’ve got a bad cold, what should you do at dinner?
A.Excuse yourself and leave for home.B.Blow your nose with a handkerchief.
C.Use some disposable tissues when neededD.Go to the restroom.
小题3:Before entering your friend’s house in a foreign country, you’d better ______.
A.greet the host or hostess firstB.follow others’ behaviors
C.remove your shoes firstD.respect their customs
