The influence of psychological needs and motivation on game cheating: insights from self-determination theory.

Introduction: Game cheating (i.e., behavior of violating rules in games by using unregulated Software or assistive devices to gain advantage) poses a fatal problem as it destroys fair competition systems and negatively impacts the game ecosystem. Game cheating is reported to be common in competitive online games because they stimulate strongly a user's motivation and psychological needs. However, there is still in lack of academic research which focused on the issue from the psycho-social perspective. Methods: This study investigated the relationships between basic psychological needs (i.e., autonomy, competence, and relatedness) and motivation (i.e., intrinsic and extrinsic) based on self-determination theory, and examined their effects on the degree of game cheating with survey data of 322 gamers in a competitive online gaming community. Results: The results showed the opposite associations between the two forms of motivation (intrinsic and extrinsic) and game cheating. On one hand, extrinsic motivation decreased by autonomy enhanced the degree of game cheating. On the other hand, intrinsic motivation increased by both autonomy and relatedness finally abated game cheating. Competence did not influence any form of motivation. The results indicated that people motivated by interest or enjoyment (i.e., intrinsic motivation) of the game tend to view game cheating negatively while those motivated by game victory and rewards are likely to have positive attitudes toward game cheating. Increasing the degree of user autonomy and social relations in the game could decrease game cheating through the enhancement of intrinsic motivation. Discussion: Digital game cheating is a crucial problem threatening the spread of game culture and the growth of the eSports industry. The findings of this study reveal the influence of psychological needs and intrinsic motivation related to 'game cheating,' providing valuable guidelines in educational and policy aspects.

How should we understand the digital economy in Asia? Critical assessment and research agenda.

By Asian digital economy, we refer to high-tech developments, business and social transformations, and information-driven changes in the region's growth. We discuss its background and foundations, significance in Asia and contribution to removal of historical barriers in traditional business. We assess how new value chains are transforming country-level involvement in worldwide manufacturing and note "smiling curve theory" predictions about the global value chain in Asia for high-tech firms and their economies. The takeaway is that the digital economy in Asian nations involves revamping business processes through technology innovation, government policies for growth, and digital entrepreneurship. We analyze the "digital economy and society index", and attributes of nations, societies and economies, as a basis for framing our ideas. We consider research directions prompted by data analytics and AI, the platform economy, digital trade, fintech innovation, and societal and economic sustainability. We further highlight new issues in light of the COVID-19 pandemic.

An audit of retinal lymphoma treatment at the University of California San Francisco.

BACKGROUND/OBJECTIVES: To evaluate retinal lymphoma treatment at the University of California San Francisco. SUBJECTS/METHODS: Prospective observational audit. Patients were treated systemically, usually with: methotrexate, temozolomide, and rituximab induction; etoposide consolidation; and maintenance with lenalidomide or another immunomodulatory agent. Persistent disease was treated initially by ocular radiotherapy or intravitreal melphalan and latterly by vitrectomy. RESULTS: The cohort comprised eight females and two males. The median age was 58 years (range, 38-73). Ocular manifestations were initially unilateral in four patients. Vitreous and subretinal infiltrates were initially present in 16 and 12 eyes, respectively, with three eyes having vision of 20/200 or worse. Four patients had a history of central nervous system (CNS) lymphoma. The median ophthalmic follow-up was 37 months (range, 8-56). Diagnostic and therapeutic vitrectomy were performed in 10 and 2 eyes, respectively. All patients had systemic chemotherapy and eight received maintenance immunotherapy. Four patients underwent ocular radiotherapy, bilaterally in two. One patient received bilateral intravitreal melphalan injections. Two eyes of four patients developed lymphoma during the study and two patients developed CNS disease. At study close, subretinal deposits were subtle in nine eyes and more prominent in two, whereas vitreous infiltrates were minimal in nine eyes, mild in one and moderate in one. The latest visual acuity was significantly worse than at presentation in two eyes and better in two. All patients were alive with no active CNS disease. CONCLUSIONS: Subretinal lymphomatous infiltrates respond to systemic chemotherapy with immunomodulatory maintenance, but dense vitreous infiltrates require therapeutic vitrectomy.

THERAPEUTIC VITRECTOMY AS AN ADJUNCT TREATMENT TO SYSTEMIC CHEMOTHERAPY FOR INTRAOCULAR LYMPHOMA.

PURPOSE: To report the outcome of a previously vitrectomized eye having less lymphoma disease burden compared with the contralateral nonvitrectomized eye over the course of 3.5 years while on systemic chemotherapy. METHODS: Case report. RESULTS: A 51-year-old man with vitreoretinal lymphoma with central nervous system involvement underwent vitrectomy in his left eye. Over the following 3.5 years on systemic chemotherapy, the left eye had less lymphoma disease burden compared with the contralateral nonvitrectomized right eye. CONCLUSION: Therapeutic vitrectomy may be a useful adjunct to systemic chemotherapy in vitreoretinal lymphoma, particularly in cases of vitreous predominant disease manifestation.
