人民检察院在作出免予起诉决定时能够责令被告人赔偿经济损失吗?

有的同志认为,人民检察院对符合免予起诉条件的被告人在作出免予起诉的同时,“可根据案件的不同情况,作出予以训诫、责令具结悔过、赔礼道歉、赔偿损失,或建议主管部门予以行政处分等处理”。注 笔者认为这是不恰当的。 第一,我国刑法第32条规定:“对于犯罪情节轻微不需要判处刑罚的,可以免予刑事处分,但可以根据案件的不同情况,予以训诫或者责令具结悔过、赔礼道歉、赔偿损失,或者由主管部门予以行政处分”。这一规定清楚地表明:人民法院在作出免予刑事处分的同时,有权根据案情,责令被告人赔偿经济损失,但是,刑法并没有将这一权利赋予人民检察院。

Monitoring actual performance of ground source heat pump system using GPRS-based data transmission: A case analysis in Tangshan

The energy efficiency monitoring is an essential precondition for ground source heat pump system's controlling and energy saving operation. Based on the data monitoring applied in the school building, this work is focused on the parameters acquisition and operation analysis of the GSHP system in Tangshan. Results show the average COPs(coefficient of performance) are2.85 and 2.70 in summer and winter, respectively, and heat(cold) unbalance underground existed after whole year operation. The analysis of data also indicates that the direct borehole air-conditioning saved some power consumption obviously in the early stage of summer and energy saving of the GSHP system depended remarkably on its operation and management level. Besides the observation points of ground temperature are laid for a large-scale GSHP system, and the hydraulic balance of the pipes group needs to be concerned specially in safeguarding better reliability.

Policy implications for community-managed forestry in Cambodia from experts＇ assessments and case studies of community forestry practice

Over the last 40 years, it has been shown at the global level that sustainable forestry can be achieved through comprehensive forest management,with the decentralized institutional arrangements of community-managed forestry coordinated by effective policy implementation. However, there is still a shortage of evidence regarding whether communitybased forestry is well characterized by forest policies,assessing what action is most needed and how best to address the challenges faced by community-based forestry in halting deforestation and promoting rural livelihoods. The study analyzed experts' assessments of the characteristics and success of communitymanaged forestry in Cambodia and explored three case studies of community-managed forestry practice to identify priorities for addressing forest policy implementation inadequacies in halting deforestation and promoting rural livelihoods. There were two methods of data collection. Firstly, this study used a survey of 27 experts to analyze perceptions about how far forest policy supported community-managed forestry effectively, the major challenges faced by the national community-managed forestry program, and the community-managed forestry contribution to halting deforestation and reducing rural poverty.Secondly, data was collected by content analysis of three case studies to explore the knowledge and practical experience of local experts about community-managed forestry practice at local level.The study employed Kendall's Coefficient of Concordance to analyze the level of concordance of experts on related forest policies(n=15) considering community-managed forestry, the challenges faced by the national community-managed forestry program,and the actions required to enable communitymanaged forestry to support communities. Analysis revealed that experts were in moderate agreement,denoted by Kendall's W=0.152, on how well forest policies articulate and implement the characteristics of community-managed forestry. Ranking of the major challenges faced by the national communitymanaged forestry program yielded Kendall's W of0.104, indicating the confidence in the ranking among experts was fair. There was only low confidence in the ranking of the action needed, with Kendall's W of0.055. Content analysis of the three case studies examining local experts' opinions on the attributes of community-managed forestry concerning the access,local participation and protection of the sustainable forestry revealed that Attribute one ‘Local people have access to the forest land and forest resources', and Attribute three ‘Local people begin by protecting and restoring the forests', received high attention from local experts. Of lesser importance or agreement was attributing two: local participation in decision-making concerning the forest.

Similarity measure design for high dimensional data

Information analysis of high dimensional data was carried out through similarity measure application. High dimensional data were considered as the a typical structure. Additionally, overlapped and non-overlapped data were introduced, and similarity measure analysis was also illustrated and compared with conventional similarity measure. As a result, overlapped data comparison was possible to present similarity with conventional similarity measure. Non-overlapped data similarity analysis provided the clue to solve the similarity of high dimensional data. Considering high dimensional data analysis was designed with consideration of neighborhoods information. Conservative and strict solutions were proposed. Proposed similarity measure was applied to express financial fraud among multi dimensional datasets. In illustrative example, financial fraud similarity with respect to age, gender, qualification and job was presented. And with the proposed similarity measure, high dimensional personal data were calculated to evaluate how similar to the financial fraud. Calculation results show that the actual fraud has rather high similarity measure compared to the average, from minimal 0.0609 to maximal 0.1667.

Energy-Efficient Transmission Scheme for Mobile Data Gathering in Wireless Sensor Networks

Energy conservation in Wireless Sensor Networks (WSNs) has always been a crucial issue and has received increased attention in the recent years. A transmission scheme for energy-constrained WSNs is proposed in this paper. The scheme, called MIHOP (MIMO and Multi-hop), combines cluster-based virtual MIMO and multi-hop technologies. The multihop mode is employed in transmitting data when the related sensors are located within a specific number of hops from the sink, and the virtual MIMO mode is used in transmitting data from the remaining sensor nodes. We compare the energy consumption of different transmission schemes and propose an algorithm for determining the optimal hop count in MIHOP. A controllable mobile sink that reduces the energy consumed in sensor transmission is also adopted for data collection. The theoretical analysis and the Monte Carlo simulation demonstrate that the proposed scheme significantly outperforms individual virtual MIMO, multi-hop technologies, and double-string networks in terms of energy conservation. The energy consumption levels under the MIHOP scheme are approximately 12.98%, 47.55% and 48.30% less than that under virtual MIMO schemes, multi-hop networks and doublestring networks, respectively.

Database-Assisted Dynamic Spectrum Access with QoS Guarantees:A Double-Phase Auction Approach

Since FCC's opening for white space(WS) utilization,database-assisted dynamic spectrum access(DSA) has become the de facto solution for the realization of dynamic spectrum sharing(DSS),due to its simplicity and compatibility with commercial off-the-shelf(COTS) devices.It is envisioned that such technology will strongly support the prosperous wireless multimedia networking(WMN) applications with satisfying QoS guarantees in the future.However,how to counter the time-frequency variant property when exploiting the WS spectrum for the provision of these services to secondary users(SUs) still remains a great challenge.In such context,a dynamic secondary access scheme for database-assisted spectrum sharing networks is proposed in this paper.In the beginning,the spectrum requirements of SUs for diverse services are modeled by considering the minimum required service data-rate and spectrum access duration.Afterwards,the spectrum demand evaluation and bidding policy are formulated based on the service classes of SUs.Furthermore,a doublephase(DP) spectrum allocation scheme,which consists of the initial resource allocation phase and resource allocation adjustment phase,is carefully designed for DSA.Finally,extensive simulations are conducted and the results demonstrate that our scheme can increase the spectrum trading revenue and adapt to varying service requirements.

An Analytical Approach for Assessing the Collapse Strength of an Unbonded Flexible Pipe

This paper presents an analytical scheme for predicting the collapse strength of a flexible pipe, which considers the structural interaction between relevant layers. The analytical results were compared with a FEA model and a number of test data, and showed reasonably good agreement. The theoretical analysis showed that the pressure armor layer enhanced the strength of the carcass against buckling, though the barrier weakened this effect. The collapse strength of pipe was influenced by many factors such as the inner radius of the pipe, the thickness of the layers and the mechanical properties of the materials. For example, an increase in the thickness of the barrier will increase contact pressure and in turn reduce the critical pressure.

A DYNAMIC CROSS-LAYER DATA QUEUE MANAGEMENT APPROACH BASED ON PRIORITY FOR DELAY-TOLERANT MOBILE SENSOR NETWORKS

This paper presents a Dynamic Cross-layer Data Queue Management approach (DC-DQM) based on priority to address the priority deviation problem in Delay-Tolerant Mobile Sensor Networks (DT-MSNs). Receiver-driven data delivery scheme is used for fast response to data transfers, and a priority based interaction model is adopted to identify the data priority. Three interactive parameters are introduced to prioritize and dynamically manage data queue. The experimental results show that it can ameliorate data delivery ratio and achieve good performance in terms of average delay.

Trends and Causes of Traffic Accidents in Dubai

This paper investigates the traffic accidents＇ trends and causes in Dubai. For this purpose, the traffic accident statistics for years 2003 to 2012 are used to examine the trends of different types of accidents and the causes of these accidents. Also, the paper determines the most common types of accidents over the study period and identifies some of the causes for these accidents. Furthermore, the paper shows the impact of the new traffic law amendments, which were issued in 2008, on the accident rates and trends. The results showed that the implementation of the traffic law amendments did not have major impact in year 2008. However, there was a significant effect of these amendments in the following years. Also, lack of awareness of traffic laws and regulations in Dubai has been proven to be one of the major causes of accidents. Finally, the paper provides some recommendations to reduce the traffic accident rates, in order to achieve the Dubai Police Department 2020 strategic goal to have zero fatalities.

The Challenges of Human Resource Management Practices in the Informal Sector in Nigeria

Unemployment in the third world countries has led to various negative and positive challenges from brain drain, increased crime cases to emergent of entrepreneurial businesses. This paper examines the Nigerian informal sector and the extent of conformity with proper human resource practices. This paper adopts survey approach in analyzing data to test whether or not SMEs can conform to global HRM practices by analyzing some variables. Graphs and simple statistics were used to test the probability of conformity of informal sector activities with HRM practices in Nigeria. This paper also relied on secondary data from Bureau of Statistics and other government agencies. Past literatures were also examined. It was discovered that due to low capital outlay and inability to access funds from financial institutions, global human resource practices like proper recruitment, training, career development are being ignored.

Effects of wind input and wave dissipation formulations on the steady Ekman current solution

The effects of different wind input and wave dissipation formulations on the steady Ekman current solution are described. Two formulations are considered: one from the wave modeling(WAM) program proposed by Hasselmann and Komen and the other provided by Tsagareli and Babanin. The solution adopted for our study was presented by Song for the wave-modifi ed Ekman current model that included the Stokes drift, wind input, and wave dissipation with eddy viscosity increasing linearly with depth. Using the Combi spectrum with tail effects, the solutions are calculated using two formulations for wind input and wave dissipation, and compared. Differences in the results are not negligible. Furthermore, the solution presented by Song and Xu for the eddy viscosity formulated using the K-Profi le Parameterization scheme under wind input and wave dissipation given by Tsagareli and Babanin is compared with that obtained for a depth-dependent eddy viscosity. The solutions are further compared with the available well-known observational data. The result indicates that the Tsagareli and Babanin scheme is more suitable for use in the model when capillary waves are included, and the solution calculated using the K-Profi le Parameterization scheme agrees best with observations.

Overview of immunosuppression in liver transplantation

Continued advances in surgical techniques and immunosuppressive therapy have allowed liver transplantation to become an extremely successful treatment option for patients with end-stage liver disease.Beginning with the revolutionary discovery of cyclosporine in the 1970s,immunosuppressive regimens have evolved greatly and current statistics confirm one-year graft survival rates in excess of 80%. Immunosuppressive regimens include calcineurin inhibitors,anti-metabolites,mTOR inhibitors,steroids and antibody-based therapies.These agents target different sites in the T cell activation cascade,usually by inhibiting T cell activation or via T cell depletion.They are used as induction therapy in the immediate periand post-operative period,as long-term maintenance medications to preserve graft function and as salvage therapy for acute rejection in liver transplant recipients. This review will focus on existing immunosuppressive agents for liver transplantation and consider newer medications on the horizon.

Ad-Hoc Broadcast Encryption wit Dynamic Revocation

In order to support the dynamics of the privileged users with low computation, communica- tion and storage overheads in receivers, a secure broadcast encryption scheme for ad hoc networks based on cluster-based structure is proposed, as Mu-Vmdharajan＇s scheme cannot securely remove subscribers with data redundancy. In the proposed scheme, we employ polynomial function and filter functions as the basic means of constructing broadcast encryption procedure in order to reduce computation and shortage overhead. Compared with existing schemes, our scheme requires low computation, corrmaunication and storage over- heads in receivers and can support the dynamics of the privileged users. Furthermore, our scheme can avoid n^assive message to exchange for estab-fishing the decryption key between members of the cluster. The analysis of security and perforrmnce shows that our scheme is more secure than Mu- Vmdharajan＇s scheme and has the same speed of encryption and decryption as theirs. So our scheme is particularly suitable for the devices with low power setting such as ad hoc networks.

Network Coding Based on Linear Block Codes for Multi-source Cooperative Relaying Networks

In order to improve link performance of future wireless relay networks,a network coding scheme with linear block codes was proposed,which could be deployed in a relay network consisting of multi-source sending data to a common base station(BS) with the assistance of one relay node.At BS,an iterative decoding structure between one cooperative decoder and a number of single-source decoders was established using the relayed network codes and source codes.Further,the extrinsic information transfer(EXIT) chart technique was used to predict and analyze the convergence behavior of iterative decoder.The analysis and simulation results show that the bit error ratio(BER) performance of the proposed scheme outperforms reference scheme under different relay network coding matrices.Compared with a reference scheme without the multisource cooperation,the proposed scheme can obtain network coding gain from the relay network while not reduce its code rate.

Task-and-role-based access-control model for computational grid

Access control in a grid environment is a challenging issue because the heterogeneous nature and independent administration of geographically dispersed resources in grid require access control to use fine-grained policies. We established a task-and-role-based access-control model for computational grid (CG-TRBAC model), integrating the concepts of role-based access control (RBAC) and task-based access control (TBAC). In this model, condition restrictions are defined and concepts specifically tailored to Workflow Management System are simplified or omitted so that role assignment and security administration fit computational grid better than traditional models; permissions are mutable with the task status and system variables, and can be dynamically controlled. The CG-TRBAC model is proved flexible and extendible. It can implement different control policies. It embodies the security principle of least privilege and executes active dynamic authorization. A task attribute can be extended to satisfy different requirements in a real grid system.
