[論文研究]怎麼樣讓推薦式廣告更有效



撰文者:羅安宇


過去有關推薦式廣告的研究通常研究其效率及如何改善效率。此外,研究已經顯示消費者特性,例如認知風格、過去瀏覽行為、過去點擊紀錄、過去購買紀錄,可以協助企業決定要將廣告要給哪些消費者。但是這些研究並不是用以對每一位使用者客製化每一個廣告


Generic Retargeting→消費者已經決定回來企業網站

Dynamic Retargeting →消費者尚未決定回來企業網站
然而,企業不知道Dynamic Retargeting 是否有效,廣告商也不知道要以什麼資料來決定將廣告放在哪些網站上、以及放廣告的時間點。



brand-level ad (generic retargeting
 dynamic retargeting 



本研究:
1.研究該公司的網站以外客製化的建議。
2.專注於個性化的個人瀏覽歷史記錄
3.研究廣告的內容應該是什麼,而不是誰應該看到這個廣告
4.消費者的喜好會是否會因為瀏覽行為而造成改變

此外,透過網際網路提供有關特定產品的資訊,例如產品評論網站,可以解決消費者的憂慮,可以比較產品的功能與特性
本研究以線上旅遊公司的Hotel 產品進行資料收集

根據本研究統計,54% 的消費者在購買此產品之前,有買過商品的經驗且參觀過相關評論網站,46%在購買商品後才去評論網站。通常來說,消費者是因為想進一步了解所購買的產品,才會在消費完之後去評論網站。
一般情況而言,Generic Retargeting會有更好的表現,若是消費者在消費前有先瀏覽過相關評論網站後,Dynamic Retargeting才會有較高的效率。

社群上,在發布訊息時受到安全、信任、隱私這三項指標影響。此論文及探討這三個指標。


而此論文的實質意義有兩點,
一、 了解在社群網路分享資訊,在意的地方
二、提供社交網站未來提出有用的策略

§ INTRODUCTION
對於社交網站用戶的,也有許多必須考慮到隱私和信任

首先,在用戶的個人資料透露的信息可能會導致像身份盜竊,網絡跟踪,和網絡騷擾等危險
其次,像新聞提要的功能使得個人信息更方便和其他人可以看見

本文重點在介紹在社交平台上分享訊息,受此三指標隱私,安全和信任影響的分析

欲了解
Q1: 在網站上面信任的前提是甚麼
Q2: 分享訊息在隱私、安全、信任上的意願

§ THEORETICAL BACKGROUND
A.社交網站上的隱私問題
1.在社交網站方面的隱私擔憂日益重要;過去一直沒有深入被研究作為
2.風險
3.線上social networking被批評

B. 隱私和信任在social networking的概念
1.信任: 一個群體,自願地讓另一個群體
2.隱私: 訊息流動時,可能會改變 或是 交換這些資訊

§ RESEARCH FRAMEWORK AND HYPOTHESIS




使用擴展TAM模型,社會交換理論所提出的研究框架實證檢驗
隱私和安全是信任的前因,舊式一定會先有隱私和安全,才會有信任

Narcissism and Social Networking Web Sites

Narcissism and Social Networking Web Sites
The Journal of Personality and Social Psychology

Abstract
The present research examined how narcissism is manifested on a social networking Web site

Coded for both objective and subjective content features,and let strangers viewed and rated their
impression of the web page owner on agentic traits, communal traits, and narcissism.
Narcissism predicted
(a) higher levels of social activity in the online community
(b) revealed several Web page content features that were influential in raters’ narcissistic
impressions of the owners, including quantity of social interaction, main photo self-promotion,and
main photo attractiveness.
Social website
Social website offer the following functions
(a)create an individual Web page
(b) Post self-relevant information (ex:self-descriptions, photos)
(c) link to other members (ex: “friends lists”)
(d) interact with other members
Offer a gateway for self-promotion via self-descriptions, vanity via photos,and large numbers of
shallow relationships
linked to trait narcissism.
Narcissism and Social Behavior
Narcissism is associated with positive and inflated self-views of agentic traits like intelligence,
power, and physical attractiveness
 (Brown & Zeigler-Hill, 2004; Campbell,Rudich, & Sedikides, 2002; Gabriel, Critelli, & Ee,1994; John & Robins, 1994)
narcissism is associated with a high degree of extraversion/agency and a low level of
agreeablenessor communion (e.g., Miller & Campbell, 2008;Paulhus & Williams, 2002)
Narcissistic在人際關係中如何運作
1. Narcissism is associated with being
(a)liked in initial interactions (Oltmanns, Friedman, Fiedler, & Turkheimer,2004; Paulhus, 1998)
(b) perceived as a leader (Brunell,Gentry, Campbell, & Kuhnert, 2006)
(c) perceived as exciting (Foster, Shrira, & Campbell, 2003)
(d) socially confident (Brunell, Campbell, Smith, & Krusemark,2004)
(e) entertaining (Paulhus, 1998)
(f) able to obtain sexual partners
2. narcissism is associated negatively with seeking out or creating long-term relationships
→ 在臨床研究上narcissism會造成身邊人的痛苦
3. narcissism is associated with using relationships as an opportunity or forum for self-
enhancementFor example, narcissists brag and show off (Buss & Chiodo, 1991)
Narcissismsocial website中如何運作:
online communities is a fertile ground for narcissists to self-regulate via social connections for two
reasons
First  narcissists function well in the context of shallow relationships. Social networking Web sites
are built on the base of superficial “friendships”  and the ability of social website often is to
maintain large numbers of relationships (e.g. many users have hundreds or even thousands of
“friends”).
Second social networking Web pages are highly controlled environments (Vazire & Gosling, 2004).
Owners have complete power over self-presentation on Web pages. In particular, one can use
personal Web pages to select attractive photographs or write self-descriptions that are self-
promoting.
They are prevalent on reality television (Young & Pinsky, 2006), and enjoy looking at themselves on
videotape and in the mirror (Robins & John, 1997).
Personal Web pages should present a similar opportunity for self-promotion.
Personality Manifestation on Web Pages
網頁的瀏覽者會因為網站owner的個人特質而投射此特質至此網站的定位
網站owner的個人特質可經由網頁中的特定內容被偵測到
→ 網站的viewer可利用網頁內容去form onwer的人格特質
The Present Research
檢驗 the role of narcissism in personal Web pages on social networking sites
本研究會將焦點著重在社群網站是因為:
1. 社群網站不只是訊息傳播更能夠self-presentation and interaction
2. 社群網站深受使用者歡迎並持續成長中
The Present Research
研究對象:facebook
Why
1.Facebook is the most commonly used site by individuals in our sample—college students
2. Facebook is the most structured social network Website
The four steps of investigation
1. Examined the link between narcissism and social activity in a Web community.
2. Inspected the associations between narcissism and the content of social networking Web pages.
narcissism should be associated with
(a)a greater amount of social activity (Hypothesis 1)
(b) self-promotion in text and pictures (Hypothesis 2).
Tested whether individuals viewing a social networking page could detect the owner’s
expression of agentic/ communal traits and level of narcissism
narcissism would be perceived by Web page observers, as would the general agentic qualities
associated with narcissism (Hypothesis 3).
narcissistic Web page content would relate positively to observers’ narcissistic impressions
(Hypothesis 4).
4. examined which social networking page content was the most influential in forming
impressions of narcissism (i.e.mediational analyses, Hypothesis 5).
METHOD
Personality data and Facebook page collection.
Personality data and Facebook page collection.
Objective Facebook page coding
Subjective Facebook page coding by research assistant (RA) raters.
Facebook page impression ratings.
Conclusion
在現在的社群網站中,interaction and self-promotion 是一個常態現象,維護在網路上
的存在和與其他大量使用者間的聯繫已變成許多使用者每天生活的一部分。本研究的目標
為研究narcissism 如何在網站中展現並從實驗結果得知 narcissists act, portray themselves,
and are perceived on social networking sites 和現實中的offline生活行為相像。本研究希望
經由這些初步的調查結果推動未來社群網路上以及其他網際項目的narcissism評估

[論文研究] 用三個面向來探討Social Identification

撰文者:李宥萱

傳統上,多將social identity作為單一的理論構念,然而在〈Self-categorisation, commitment to the group and group self-esteem as related but distinct aspects of social identity〉一文中,將social identity分為三個面向討論,分別為: 
  • the cognitive aspect of social identity: self-categorize as group members
  • the evaluative aspect of social identity: group self-esteem:
  • the emotional aspect of social identification: affective commitment to the group

[論文研究]When Facebook is easier than face-to-face Social support derived from Facebook in socially anxious individuals

Abstract
  雖然社會支持(social support)帶來的心理上好處是被證實的,但許多對社交焦慮之個體要參與face-to face的社群網路中仍有問題。因此本研究將檢驗是否從線上社群網絡衍伸而來(像是FB)的社會支持,在預測個人的行為超越且在offline社會支持的社會焦慮和非社會焦慮的個體之上有增加的價值

何謂Social support?
社會支持是一種廣泛存在的社會現象,主要是指人與人之間的交流和交流的結果
S. Cobb:人們彼此交換訊息的過程,可使個人感受到被關愛、受尊重、有價值感和隸屬某個社會網絡等方面之滿足。
J.S. House: 指出社會支持可分為情感性支持、實質性支持、知識性支持和評價性支持等四類
  1. 情感性支持: 有關同情心、喜愛、信任和照料的提供。
  2. 實質性支持: 提供者對需求者提供實際的幫忙和服務。
  3. 知識性支持: 針對個體在解決其所面對的困難時,提供者給予勸告、建議和知識性資料。
  4. 評價性支持: 採用回饋、社會比較或肯定的方式,以達到自我評價的目的。 
Introduction
社群焦慮者仍然對接觸其他人與得到社會支持有障礙。由於最近線上社群興起,這個研究打算調查由使用FB所衍生出第一次社會支持,以及其與社群焦慮(and社群非焦慮者)的幸福感之關聯性為何。
Social interactions in the online environment
後來研究提出,Internet的使用環境變化和社群媒體的興起可以促進社會支持和連接。而近期研究也指出,社群連結與使用FB會讓人感到快樂且增進心智健康。

Social anxiety and the online environment
Morahan-Martin 和Schumacher提出,Internet可以提供一個有吸引力的選擇以增加社會互動來削減社會憂慮,這表明有些人可能是為了體驗社會互動和社會陪伴而被吸引到Internet結果為孤獨的參與者比非孤獨的參與者有更多的網路上社會互動和社會陪伴。

Method---Participants
299Facebook users(257 女,42 )
平均年齡28.35 years (SD = 10.88 years)
樣本83.3%使用FB兩年以上
參與者平均有200~250FB好友;每天用FB30~60 min14%每天超過3 hr

It seemed that Facebook use was occurring at sufficient levels to allow perceptions of social support to emerge

Method--- Measures
Social anxiety
mini-social phobia inventory (Mini-SPIN)
Offline social support
appraisal subscale of the interpersonal support evaluation list
Facebook social support items
Subjective well-being
Design, analytical approach, and procedure

A cross-sectional design was used. Data was split into high and low social anxiety groups based on the cut-off recommended by Seeley-Wait et al. (2009).
Results
  由於樣本是女性為主,審慎的做法是檢查性別的系統性影響性別對任何變數沒有顯著影響(p values were between 0.13 and 0.69)。相關多元假設也被檢查並全部獲得滿足的後續分析。

Descriptive statistics
Descriptive statistics for the high and low social anxiety groups and for the whole sample are presented in Table 1.
α=0.0125
The high social anxiety group reported significantly greater social anxiety, t(297) = 25.88,p<0.001
Significantly lower levels of satisfaction with life, t(297) = 5.10, p<0.001

And significantly lower perceptions of social support experienced offline, t(297) = 2.87, p = 0.004, than individuals in the low social anxiety group.

Discussion
如預期: For both the low- and high- social anxiety groups, offline Facebook 社會支持可以顯著預測社會幸福感。
不如預期: Facebook社會支持並沒有為low social anxiety group解釋任何超越且offline社會支持之上的幸福感變數,這表明來自Facebook獲得的社會支持在促進個人社會幸福感之效用有限
然而如預測high social anxiety groups Facebook的社會支持在解釋更多額外超越且在offline社會支持之上的幸福感變數。
Facebook的互動可以很容易地促進改善社交焦慮者的幸福感,從而提高其運作和經驗。然而,這個概念有另一種解釋和推論存在。特別是如果社交焦慮者轉向網絡環境社會支持,同時避免在臉上地面對環境的社會互動,這可能會隨後延續他們的社交焦慮

虛擬療法(virtual therapies)的使用率可能因此提高,目前的研究結果必須在可能的治療方案這方面進行考慮

Conclusion
  雖然這些研究結果表明,Facebook對社交焦慮者社會支持的感知來說可能成為一個有效平台社交焦慮和可能延續的因素的性質意味著這項研究的意義應該再將更廣泛的臨床範圍納入考慮
