我国彩票购买人群的心理行为特征及购彩成瘾倾向研究

The aims of this research were to explore Chinese lottery buyers’ and addictive buyers’ characteristics and influencing factors of lottery buying．Three studies were carried out: study 1 was to find out the psychological and behavioral characteristics of Chinese lottery buyers. Study 2 was to find out the psychological and behavioral characteristics of addictive lottery buyers. High addictive tendency group and control group were selected, and general information, personality traits and lottery buying behavior characteristics were compared between the two groups. Study 3 was to explore the influences of locus of control and coping style on Chinese lottery buyers’ addictive tendency. 7,160 subjects were rectuited from the Welfare Betting shops in 114 cities of the 31 provinces of China. It was found that: 1. The main characteristics of Chinese lottery buyers are: male, marride, non-religious, 26-45 years old, having at least high school level of education. 2. Chinese lottery buyer’s reasons of first buying were curiosity, to donate for charity, to have amusement, to chase big prize and others’ influence. At present the main reasons of lottery buying were charity, amusment and big prize. 3. 40 percent of Chinese lottery buyers spent more than 20% of their income on lottery. Higher income buyers spent more than the lower ones, but the lower income buyers’ ratio of lottery buying money per month was higher than that of the higher income ones. 4. Chinese high addictive lottery buyers’ characteristics were middle-aged, married, low educational and low-income males . 5. Lottery buyers’ buying behavior is reinforced with lottery winning ratio during the first lottery buying . The addictive tendency of lottery buying is unrelated with the length of lottery buying experience. 6. External control, negative coping style and education level, are associated with the high addictive lottery buying behavior.

CloudNeg: An autonomous multi issue negotiation system, with preference elicitation component, for trading cloud services

Cloud services provide its users with flexible resource provisioning. But in the current market, a user has to choose from a limited set of configurations at a fixed price. This paper presents an autonomous negotiation system termed CloudNeg for negotiating cloud services. CloudNeg provides buyers and sellers of cloud services with autonomous agents to negotiate on the specifications of a cloud instance, including price, on their behalf. These agents elicit their buyers’ time preferences and use them in negotiations. Further, this paper presents two artifacts: a negotiation algorithm and a prototype which together form CloudNeg.

A theory of buyer-seller networks

This paper introduces a new model of exchange: networks, rather than markets, of buyers and sellers. It begins with the empirically motivated premise that a buyer and seller must have a relationship, a "link," to exchange goods. Networks - buyers, sellers, and the pattern of links connecting them - are common exchange environments. This paper develops a methodology to study network structures and explains why agents may form networks. In a model that captures characteristics of a variety of industries, the paper shows that buyers and sellers, acting strategically in their own self-interests, can form the network structures that maximize overall welfare.

Global value Chains, rising power firms and economic and social upgrading

© Emerald Group Publishing Limited.Purpose – The purpose of this paper is to introduce the global value chain (GVC) approach to understand the relationship between multinational enterprises (MNEs) and the changing patterns of global trade, investment and production, and its impact on economic and social upgrading. It aims to illuminate how GVCs can advance our understanding about MNEs and rising power (RP) firms and their impact on economic and social upgrading in fragmented and dispersed global production systems. Design/methodology/approach – The paper reviews theGVCliterature focusing on two conceptual elements of the GVC approach, governance and upgrading, and highlights three key recent developments in GVCs: concentration, regionalization and synergistic governance. Findings – The paper underscores the complicated role of GVCs in shaping economic and social upgrading for emerging economies, RP firms and developing country firms in general. Rising geographic and organizational concentration in GVCs leads to the uneven distribution of upgrading opportunities in favor of RP firms, and yet economic upgrading may be elusive even for the most established suppliers because of power asymmetry with global buyers. Shifting end markets and the regionalization of value chains can benefit RP firms by presenting alternative markets for upgrading. Yet, without further upgrading, such benefits may be achieved at the expense of social downgrading. Finally, the ineffectiveness of private standards to achieve social upgrading has led to calls for synergistic governance through the cooperation of private, public and social actors, both global and local. Originality/value – The paper illuminates how the GVC approach and its key concepts can contribute to the critical international business and RP firms literature by examining the latest dynamics in GVCs and their impacts on economic and social development in developing countries.

When deterrence works - and when it doesn't: a comparison of Sweden's prostitution law and UK's Dangerous Dogs Act

Many pieces of legislation have been implemented with the anticipation - or justification - that they will have a deterrent effect. Deterrence was clearly argued in the debate preceding the Swedish prostitution law prohibiting the purchase of sexual services, but less so regarding the Dangerous Dogs Act, which was a very rapid response to a particular moral panic. As it turned out, the Swedish law has had a deterrent effect on street prostitution in that 'respectable' buyers were deterred. It will be argued that it is this very 'respectability' that makes deterrence work in this case. Regarding the Dangerous Dogs Act, the owners of Pit Bulls and other banned breeds are not considered 'respectable' and the banning might have had the reversed effect - increasing the attraction of these dogs, rather than deterring the ownership. Apart from deterrence and its consequences, the rendering invisible of key actors - buyers and owners respectively - and the use of symbolic legislation to promote moral messages will also be considered.

The determinants of knowledge transfer within collaborative new product development projects

Purpose – This paper explores the factors which determine the degree of knowledge transfer in inter-firm new product development projects. We test a theoretical model exploring how inter-firm knowledge transfer is enabled or hindered by a buyer’s learning intent, the degree of supplier protectiveness, inter-firm knowledge ambiguity, and absorptive capacity. Design/methodology/approach – A sample of 153 R&D intensive manufacturing firms in the UK automotive, aerospace, pharmaceutical, electrical, chemical, and general manufacturing industries were used to test the framework. Two-step structural equation modeling in AMOS 7.0 was used to analyse the data. Findings – Our results indicate that a buyer’s learning intent increases inter-firm knowledge transfer, but also acts as an incentive for suppliers to protect their knowledge. Such defensive measures increase the degree of inter-firm knowledge ambiguity, encouraging buyer firms to invest in absorptive capacity as a means to interpret supplier knowledge, but also increase the degree of knowledge transfer. Practical implications – Our paper illustrates the effects of focusing on acquisition, rather than accessing, supplier technological knowledge. We show that an overt learning strategy can be detrimental to knowledge transfer between buyer-supplier, as supplier’s react by restricting the flow of information. Organisations are encouraged to consider this dynamic when engaging in multi-organisational new product development projects. Originality/value – This paper examines the dynamics of knowledge transfer within inter-firm NPD projects, showing how transfer is influenced by the buyer firm’s learning intention, supplier’s response, characteristics of the relationship and knowledge to be transferred.

Restorative justice conferencing for reducing recidivism in young offenders (aged 7 to 21)

Background
Restorative justice is “a process whereby parties with a stake in a specific offence resolve collectively how to deal with the aftermath of the offence and its implications for the future” (Marshall 2003). Despite the increasing use of restorative justice programmes as an alternative to court proceedings, no systematic review has been undertaken of the available evidence on the effectiveness of these programmes with young offenders. Recidivism in young offenders is a particularly worrying problem, as recent surveys have indicated
the frequency of re-offences for young offenders has ranged from 40.2% in 2000 to 37.8% in 2007 (Ministry of Justice 2009)

Objectives
To evaluate the effects of restorative justice conferencing programmes for reducing recidivism in young offenders.

Search methods
We searched the following databases up to May 2012: CENTRAL, 2012 Issue 5, MEDLINE (1978 to current), Bibliography of Nordic Criminology (1999 to current), Index to Theses (1716 to current), PsycINFO (1887 to current), Social Sciences Citation Index (1970 to current), Sociological Abstracts (1952 to current), Social Care Online (1985 to current), Restorative Justice Online (1975 to current), Scopus (1823 to current), Science Direct (1823 to current), LILACS (1982 to current), ERIC (1966 to current), Restorative Justice Online (4May 2012),WorldCat (9May 2012), ClinicalTrials.gov (19May 2012) and ICTRP (19May 2012). ASSIA,National Criminal Justice Reference Service and Social Services Abstracts were searched up to May 2011. Relevant bibliographies, conference programmes and journals were also searched.

Selection criteria
Randomised controlled trials (RCTs) or quasi-RCTs of restorative justice conferencing versus management as usual, in young offenders.

Data collection and analysis
Two authors independently assessed the risk of bias of included trials and extracted the data. Where necessary, original investigators were contacted to obtain missing information.

Main results
Four trials including a total of 1447 young offenders were included in the review. Results failed to find a significant effect for restorative justice conferencing over normal court procedures for any of the main analyses, including number re-arrested (odds ratio (OR) 1.00, 95% confidence interval (CI) 0.59 to 1.71; P = 0.99), monthly rate of reoffending (standardised mean difference (SMD) -0.06, 95% CI -0.28 to 0.16; P = 0.61), young person’s remorse following conference (OR 1.73, 95% CI 0.97 to 3.10; P = 0.06), young person’s recognition of wrongdoing following conference (OR 1.97, 95% CI 0.81 to 4.80; P = 0.14), young person’s self-perception following conference (OR 0.95, 95% CI 0.55 to 1.63; P = 0.85), young person’s satisfaction following conference (OR 0.42, 95% CI 0.04 to 4.07; P = 0.45) and victim’s satisfaction following conference (OR 4.05, 95%CI 0.56 to 29.04; P = 0.16). A small number of sensitivity analyses did indicate significant effects, although all are to be interpreted with caution.

Authors’ conclusions
There is currently a lack of high quality evidence regarding the effectiveness of restorative justice conferencing for young offenders. Caution is urged in interpreting the results of this review considering the small number of included studies, subsequent low power and high risk of bias. The effects may potentially be more evident for victims than offenders. The need for further research in this area is highlighted.

Temper outbursts in Prader-Willi syndrome: causes, behavioural and emotional sequence and responses by carers

Background: Temper outbursts are common in Prader-Willi syndrome but rarely described in detail. This study investigated the phenomenology of temper outbursts in terms of antecedents, sequence of behaviours and emotions and intervention strategies used.

Method: A semi-structured interview about temper outbursts was conducted with the main carers of seven children (9.5 to 16.7 years) and seven adults (24.7 to 47.10 years) with Prader-Willi syndrome (10 male, 4 female). Reliability and validity of the interview results was established.

Results: Various setting events increased and reduced the likelihood of temper outbursts. The most common antecedent was a change to routine or expectation. There were marked similarities in the sequence of behaviours and emotions during temper outbursts, with anger rising quickly followed by expressions of remorse and distress at the end of an outburst.

Discussion: The sequence of behaviours and emotions within outbursts was similar to that described in temper tantrums in typical development. Cognitive and emotional processes are likely to be important in the understanding of temper outbursts with implications for early intervention.

Optimal Front Page Advertising

We consider a model of an on-line software market, where an intermediary distributes products from sellers to buyers. When products of sellers are vertically differentiated, an intermediary, earning a proportion of sales, has an incentive to hide the worse product on the second page, and only keep the better product on the front page: that weakens the competition, allowing the seller with the better product to charge a higher price. With heterogeneous visiting costs to the second page, the platform's revenue might improve, but the outcome will become socially suboptimal.

Why Putin has pulled Russia out of Syria

By formally quitting during a ceasefire he himself masterminded – and on the back of significant military gains – Putin can leave with his head held high. Having proven his critics wrong and demonstrated the capability of Russia’s military (and its new weapons – a splendid advert to any buyers of Russian arms), Putin can now concentrate on the diplomatic aspect of the peace process, something at which Moscow usually excels.

Contracts for the Sale of Land: Understanding the Impecuniosity Defence

Where either the seller or buyer of landed property fails to complete a contract to sell land the non-breaching party has a right to seek specific performance of the contract. This remedy would compel the party in default to perform the contract on pain of being held in contempt of court if the court's order is not obeyed. The defaulting party would not be able to satisfy its obligations under the law by paying a sum of money as damages for breach of contract. This paper considers the impecuniosity defence to specific performance as recognised by courts in Northern Ireland, the Republic of Ireland, Australia and New Zealand. Where the buyer demonstrates that he or she simply cannot raise the funds to buy the property specific performance will not be decreed and the court will make an award of damages for breach of contract measured by the difference between the contract price and the market price of the property at the time of default. The paper considers the nature and parameters of this defence and how it differs (if at all) from the alternative defence of extreme hardship. The paper addresses the question of whether it might be better to move to a position where sellers of land in all cases no longer enjoy a presumption of specific performance but have to demonstrate that the alternative remedy of damages is clearly inadequate. If this should be so the paper goes on to consider whether abolition of the presumption in favour of specific performance for sellers should lead to abolition of the presumption of specific performance for buyers, as is the position in Canada following the Supreme Court's decision in Semelhago v Paramadevan [1996] 2 SCR 415.

Factoring in family freight forwarder company: case study

Each freight forwarder company must independently determine whether factoring is the right choice for them and if will pay off. If the factoring as a financial method would not be economically viable, it certainly would not exist. There are several different financing methods, which are more or less useful. However, not all of them are appropriate for every company, just like all buyers do not represent equal risks for the suppliers. The same buyer can pay one supplier within the agreed period, and not pay the other supplier at all. Still, the most important elements are the agreement made with the customer, the method of insuring ourselves and the method of monitoring the implementation of the agreements. Problems rarely occur overnight and that is why we have to constantly supervise our buyers; otherwise account receivables can occur. My thesis contributes to the ongoing research into how the use of factoring within the Slovenian economic environment can help a small freight forwarder company to grow. In effect, the specific characteristics of the Slovenian economic, legal and institutional environment make such an analysis an interesting one to explore. I used data from a family freight forwarder company TOP Hrvatin in drugi d.n.o. in order to establish future company growth by applying factoring as a right choice of financing. After applying all the data and preparing the company's financial plan, my results suggest that factoring is not the right choice for financing future investments for this particular freight forwarder business. Furthermore, the results even show that factoring is an extremely undeveloped financing method in Slovenia and that practically there is no legal base for its use.

Adulteration and Poor Quality of Ginkgo biloba Supplements

Adulteration of Ginkgo products sold as unregistered supplements within the very large market of Ginkgo products (reputedly £650 million annually) through the post-extraction addition of cheaper (e.g. buckwheat derived) rutin is suspected to allow sub-standard products to appear satisfactory to third parties, e.g. secondary buyers along the value chain or any regulatory authorities. This study was therefore carried out to identify products that did not conform to their label specification and may have been actively adulterated to enable access to the global markets. 500 MHz Bruker NMR spectroscopy instrumentation combined with Topspin version 3.2 and a CAMAG HPTLC system (HPTLC Association for the analysis of Ginkgo biloba leaf) were used to generate NMR spectra (focusing on the 6–8 ppm region for analysis) and chromatograms, respectively. Out of the 35 samples of Ginkgo biloba analysed, 33 were found to contain elevated levels of rutin and/or quercetin, or low levels of Ginkgo metabolites when compared with the reference samples. Samples with disproportional levels of rutin or quercetin compared with other gingko metabolites are likely to be adulterated, either by accident or intentionally, and those samples with low or non-existent gingko metabolite content may have been produced using poor extraction techniques. Only two of the investigated samples were found to match with the High-Performance Thin-Layer Chromatography (HPTLC) fingerprint of the selected reference material. All others deviated significantly. One product contained a 5-hydroxytryptophan derivative, which is not a natural constituent of Ginkgo biloba. Overall, these examples either suggest a poor extraction technique or deliberate adulteration along the value chain. Investigating the ratio of different flavonoids e.g. quercetin and kaempferol using NMR spectroscopy and HPTLC will provide further evidence as to the degree and kind of adulteration of Gingko supplements. From a consumer perspective the equivalence in identity and overall quality of the products needs to be guaranteed for supplements too and not only for products produced according to a quality standard or pharmacopoeial monograph.
