Traffic capacity is critical for various networks and strongly depends on the distribution of link's bandwidth resources. In this paper, we propose a betweenness-based bandwidth allocation strategy in which the bandwidth of each link lij is allocated proportionally to the product (1 + Bi)α(1 + Bj)α, where α is a tunable parameter, and Bi and Bj are the betweenness of node i and node j, respectively. The optimal value of α is achieved by extensive simulations and slightly increases with the network size. Our new bandwidth allocation strategy achieves the highest traffic capacity when compared with the average bandwidth allocation strategy and the previously proposed degree-based bandwidth allocation strategy. Our work will be beneficial for network service providers to improve the traffic capacity by efficiently allocating or reallocating the overall finite link's bandwidth resources of networks such as the Internet, urban transport networks and airway networks.

Social Network Size

Previous studies showed that extraversion influences social network size. However, it is unclear how extraversion affects the size of different layers of the network, and how extraversion relates to the emotional intensity of social relationships. We examined the relationships between extraversion, network size, and emotional closeness for 117 individuals. The results demonstrated that extraverts had larger networks at every layer (support clique, sympathy group, outer layer). The results were robust and were not attributable to potential confounds such as sex, though they were modest in size (raw correlations between extraversion and size of network layer, .20 < r < .23). However, extraverts were not emotionally closer to individuals in their network, even after controlling for network size. These results highlight the importance of considering not just social network size in relation to personality, but also the quality of relationships with network members.

Sales Strategy

Strategi penjualan atau pemasaran adalah suatu seleksi sasaran yang menentukan posisi persaingan dan bauran dalam transaksi jual beli. Dalam strategi yang diterapkan penjualan atau pemasaran di swalayan dapat dibagi menjadi beberapa bentuk: a) Strategi Produk, b) Strategi Harga, c) Strategi Distribusi, d) Strategi Promosi. Swalayan Surya Gondang memiliki dua strategi yang dapat diterapkan, yaitu strategi harga yang terdapat dalam penetapan harga berupa POP (Point of Price) dan strategi promosi terhadap barang tertentu dengan sistem promo terdapat pada barang komoditas. Penetapan harga yang berupa POP  (Point of Price) yang terdapat di etalase rak barang komoditas di mana hal tersebut merupakan kesepakatan harga antara pihak swalayan dengan konsumen (pelanggan). Sedangkan strategi yang terjadi pada promosi diterapkan dalam sistem promo dibagi menjadi 10 macam promo (diskon, murah, 3 hari saja, awal bulan, akhir bulan, home care, beauty fair, kitchen fair, kids and baby fair, dan heboh). Hal tersebut dilakukan untuk menarik minat konsumen agar mau berbelanja di Swalayan Surya Gondang. Penelitian yang dilakukan mempunyai sebuah tujuan untuk mengetahui bagaimana strategi di Swalayan Surya Gondang dengan menggunakan jenis pendekatan secara langsung atau lapangan (field research), sedangkan jenis penelitian adalah kualitatif. Data yang diperoleh berupa data primer dan sekunder, sebagaimana yang terdapat dalam metode pengumpulan data dengan cara wawancara dan telaah dokumentasi. Dalam menganalisis data, peneliti menggunakan teknik analisis data kualitatif. Dari hasil penelitian yang dilakukan oleh peneliti bahwa Swalayan Surya Gondang mempunyai 2 strategi untuk menarik minat konsumen (pelanggan) yaitu berupa penetapan harga yang ada pada POP (Point of Price) tidak sesuai dengan database komputer sehingga terjadi perubahan lafal ijab dan qabul. Strategi  selanjutnya  yaitu  berupa promo yang terdapat pada barang komoditas berupa promo diskon di mana telah ditemukan adanya ketidakjujuran terhadap barang yang mendapat promo diskon, yang ditemukan penutupan logo promo pada masa kadaluwarsa yang menyebabkan pihak konsumen (pelanggan) tidak megetahui kapan masa kadaluwarsa akan habis. Kata Kunci: Strategi, Penjualan Barang, Swalayan.ABSTRACT:The sales or marketing strategy is a target selection that determines the position of competition and mix in buying and selling transactions. In the strategy applied sales or marketing in supermarkets can be divided into several types; a) Product Strategy, b) Price Strategy, c) Distribution Strategy, d) Promotion Strategy. Surya Gondang Supermarket has two strategies that can be implemented, the price strategy in pricing in the form of POP (Pont of Price) and in the form of a promotion strategy for certain goods with the promo system in commodity goods. Pricing in the form of a Point (POP) that is contained in a commodity shop window where it is a price agreement between a supermarket and a customer. While the strategy that occurred in the promotion was implemented in the promo system divided into 10 kinds of promos (discounts, cheap, just 3 days, the beginning of the month, the end of the month, home care, beauty fair, kitchen fair, kids and baby fair, and excited). This was done to attract consumers to shop in Surya Gondang Supermarket. The research conducted has a purpose to find out how the strategy in Surya Gondang Supermarkets uses the type of approach directly or in the field (field research), while the type of research is qualitative. Data obtained in the form of primary and secondary data, as contained in the method of data collection by means of interviews and documentation. In analyzing data, researchers used qualitative data analysis techniques. From the results of research conducted by researchers that Surya Gondang Supermarket has 2 strategies to attract consumers (customers), they are; in the form of pricing in the POP (Point Of Price) that is not in accordance with computer databases so that changes in lafadz ijab and qabul occur. The next strategy is in the form of promos contained in commodity goods in the form of discount promos where there has been a dishonesty of the goods that received a discount promo, which found closure of the promo logo on expiration which causes the consumer (customer) not to know when the expiration will expire.

Personality factors affect the properties of ‘offline’ social networks, but how they are associated with the structural properties of online networks is still unclear. We investigated how the six HEXACO personality factors (Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness and Openness to Experience) relate to Facebook use and three objectively measured Facebook network characteristics - network size, density, and number of clusters. Participants (n = 107, mean age = 20.6, 66% female) extracted their Facebook networks using the GetNet app, completed the 60-item HEXACO questionnaire and the Facebook Usage Questionnaire. Users high in Openness to Experience spent less time on Facebook. Extraversion was positively associated with network size and the number of network clusters (but not after controlling for size). These findings suggest that personality factors are associated with Facebook use and the size and structure of Facebook networks, and that personality is an important influence on both online and offline sociality.

Ecological Momentary

Social impairment is a cardinal feature of schizophrenia spectrum disorders (SZ). Smaller social network size, diminished social skills, and loneliness are highly prevalent. Existing, gold-standard assessments of social impairment in SZ often rely on self-reported information that depends on retrospective recall and detailed accounts of complex social behaviors. This is particularly problematic in people with SZ given characteristic cognitive impairments and reduced insight. Ecological Momentary Assessment (EMA; repeated self-reports completed in the context of daily life) allows for the measurement of social behavior as it occurs in vivo, yet still relies on participant input. Momentary characterization of behavior using smartphone sensors (e.g., GPS, microphone) may also provide ecologically valid indicators of social functioning. In the current study we tested associations between both active (e.g., EMA-reported number of interactions) and passive (GPS-based mobility, conversations captured by microphone) smartphone-based measures of social activity and measures of social functioning and loneliness to examine the promise of such measures for understanding social impairment in SZ. Our results indicate that passive markers of mobility were more consistently associated with EMA measures of social behavior in controls than in people with SZ. Furthermore, dispositional loneliness showed associations with mobility metrics in both groups, while general social functioning was less related to these metrics. Finally, interactions detected in the ambient audio were more tied to social functioning in SZ than in controls. Findings speak to the promise of smartphone-based digital phenotyping as an approach to understanding objective markers of social activity in people with and without schizophrenia.

Background: Cloud platform is widely used in electric power field. Virtual machine co-resident attack is one of the major security threats to the existing power cloud platform. Objective: This paper proposes a mechanism to defend virtual machine co-resident attack on power cloud platform. Method: Our defense mechanism uses the DBSCAN algorithm to classify and output the classification results through the random forest and uses improved virtual machine deployment strategy which combines the advantages of random round robin strategy and maximum/minimum resource strategy to deploy virtual machines. Results: we made a simulation experiment on power cloud platform of State Grid and verified the effectiveness of proposed defense deployment strategy. Conclusion: After the virtual machine deployment strategy is improved, the coverage of the virtual machine is remarkably reduced which proves that our defense mechanism achieves some effect of defending the virtual machine from virtual machine co-resident attack.
