تئوری انتخاب در یک تعریف ساده، تئوری انتخاب در مورد انتخابها و چگونگی و چرائی انجام آنهاست. تئوری انتخاب تبیین میکند که ما به عنوان یک انسان برای دست یافتن به آنچه میخواهیم، چگونه رفتارمان را انتخاب میکنیم. بر اساس این تئوری تمامی آنچه ما انجام میدهیم یک رفتار است و نیز اینکه همه رفتارها عمدی بوده و از درون ما برانگیخته میشوند. این برخلاف نظر نظریههایی است که میگویند ما در دنیایی از کنترل بیرونی به سر میبریم و توسط عوامل بیرونی برانگیحته میشویم. چهار مفهوم بنیادین در تئوری انتخاب عبارتند از:
نیازها
خواستهها یا دنیای مطلوب
دنیای ادراکی
رفتار
در یک نگاه کلی تئوری انتخاب بر این دیدگاه استوار است که رفتارهای هر انسان انتخابهای او برای ارضای نیازهایش است. این رفتارهای هدفمند بیشتر از انگیزههای درونی ریشه میگیرند تا عوامل و محرکهای بیرونی. این دیدگاه در بردارنده این مضمون است که رفتار ما در هر زمان بهترین تلاش ما برای کنترل دنیای پیرامونمان و نیز خودمان به عنوان بخشی از این دنیا است، بنابراین ما باید همواره به گونهای رفتار و انتخاب کنیم که به بهترین نحو نیازهایمان را برآورده کنیم. طبق این دیدگاه رفتار هر شخص در هر مقطع زمانی بهترین تلاش وی برای ارضای نیازهایش است. اگرچه شاید این تلاش در واقع مؤثر و مفید نباشد، ولی در عین حال بهترین تلاش او است و به همین دلیل روشهای واقعیتدرمانی سعی دارد مراجعان را یاری نماید تا از این جنبه که آیا رفتاری که اکنون انتخاب کردهاند نیازهایشان را برآورده میکند یا خیر و نیز اینکه آیا به خواستههایشان رسیدهاند یا نه رفتارهای خود را ارزیابی نمایند.
پنج نیاز اساسی انسان بر اساس تئوری انتخاب:
نیاز به بقا؛
نیاز به عشق و احساس تعلق؛
نیاز به قدرت (موفقیت، ارزشمندی شخصی، شهرت)؛
نیاز به آزادی و خودمختاری؛
نیاز به تفریح.
This document discusses MIMO (Multiple Input Multiple Output) technology. It begins by introducing MIMO, MISO and SIMO systems. It then presents the MIMO channel model as a matrix equation showing the relationship between the transmitted vector, channel matrix and received vector. It explains that MIMO can provide diversity gain through diversity techniques or multiplexing gain through spatial multiplexing techniques. This allows MIMO to improve reliability or data rates respectively. The document also discusses applications of MIMO such as in 3G, WiMAX and 4G LTE networks.
Multiple Input Multiple Output (MIMO) technology uses multiple antennas at both the transmitter and receiver to improve channel robustness and throughput. By utilizing reflected signals, MIMO can provide gains in channel robustness and throughput. MIMO was initially developed in the 1990s after additional processing power made it possible to utilize both spatial diversity and spatial multiplexing. MIMO systems provide either spatial multiplexing gain to maximize transmission rate or diversity gain to minimize errors and prioritize reliability. MIMO is now used in many wireless communication standards and ongoing research aims to develop more advanced MIMO techniques.
The document discusses massive MIMO technology. It defines massive MIMO as using a very large number of antennas at base stations to serve many users simultaneously. Key benefits include high spectral and energy efficiency. It explains that massive MIMO differs from conventional MU-MIMO by benefiting greatly from excess antennas. The document also covers topics like TDD vs FDD operation, pilot contamination issues and potential mitigation techniques, and synergies with mmWave networks.
The document provides an overview of MIMO (multiple-input multiple-output) systems in wireless communications. It discusses how MIMO can provide array gain, diversity gain, and multiplexing gain to improve spectral efficiency, coverage, and quality of service. It also describes how MIMO reduces co-channel interference. The document covers MIMO channel models and capacity results for different scenarios. It concludes by discussing how MIMO can be used to maximize diversity or throughput through different transmission techniques.
This document discusses multiple-input multiple-output (MIMO) systems. It begins by outlining the motivations and aspirations for developing MIMO systems, including achieving high data rates near 1 gigabit/second while maintaining quality of service. It then provides an overview of MIMO system modeling and capacity studies. Key topics covered include diversity versus spatial multiplexing design criteria, example architectures, MIMO with orthogonal frequency-division multiplexing, and networking applications involving MAC protocols.

This document proposes a model for assessing the scientific performance of social science researchers in Mexico that considers factors beyond bibliometric indicators. It will integrate variables of scientific production, teaching activities, professional involvement, and scholarly recognition. A stratified random sample of 227 researchers from the Mexican National Researchers System will be analyzed using their CVs. Preliminary findings show differences in publishing patterns between researcher levels and fields. The study aims to determine the relative impacts of the four variable groups on scientific performance.
This portfolio document shares examples of macro, architectural, abstract, and portrait photography selected by Joshua Griffin. For the macro photos, Griffin notes they show the detail and passion of nature. The architectural photo looks futuristic while being based on nature. For the abstract images, one shows pure abstract design while the other forms color abstractly. The portrait photos show happiness in two different ways, one smug and the other thinking.

This document defines and compares disassemblers, debuggers, and decompilers. It then discusses the IDA Pro tool in more detail. A disassembler translates machine code back to assembly code, enabling static code analysis. A debugger also disassembles code but allows controlled execution and dynamic analysis. A decompiler translates machine code into high-level code. The document recommends IDA Pro as a powerful disassembler and debugger that has become a standard for reverse engineering. It also briefly mentions the open-source x64dbg debugger as an alternative.
Snort is an open-source network intrusion detection and prevention system that performs real-time traffic analysis and packet logging on IP networks. It can detect a variety of attacks through protocol analysis, content searching, and matching. Snort functions in sniffer, packet logger, and intrusion detection modes. As a network intrusion detection system, it monitors network traffic and compares it to a database of attack signatures. Snort rules are used to detect suspicious activity and are organized into categories covering web, SQL, shellcode attacks and more.
This document discusses static and dynamic linking of libraries in Windows. It explains how dynamic linking loads libraries into memory alongside applications rather than copying code into each executable. It then covers dynamic link libraries (DLLs) and how their exported functions can be accessed via name or index number. The document focuses on DLL injection techniques used by malware to manipulate process execution, including loading a malicious DLL via the LoadLibrary and GetProcAddress APIs or modifying registry entries.
This document discusses SQL injection in Java applications. It defines SQL injection as a vulnerability that allows attackers to hijack databases. The document covers different types of SQL injections like boolean-based, union-based, time-based, and error-based injections. It provides examples of SQL injection vulnerabilities in Java code and how to prevent them by using prepared statements with parameterized queries, stored procedures, input validation, escaping user input, enforcing least privilege, and using tools to detect vulnerabilities.
This document discusses techniques for analyzing malware samples without executing them. It covers static analysis methods like identifying the file type and architecture, fingerprinting with hashes, scanning for known signatures, extracting strings, analyzing the PE header, and comparing samples. The goal of static analysis is to learn as much as possible about the malware before executing it, in order to focus subsequent dynamic analysis efforts. Manual and automated tools are described throughout for performing static analysis tasks like string extraction, unpacking obfuscated files, and classifying samples.
Steve Jobs visited Xerox PARC in 1979 and was inspired by the graphical user interface (GUI) he saw, including the mouse. However, he wanted to create something appropriate for mass audiences rather than just reproduce what was seen. Creativity involves generating something new and valuable. Creative leadership combines leadership and creativity to inspire and implement imaginative solutions. Effective creative leaders engage diverse teams, encourage collaboration, provide intellectual challenges to motivate intrinsic motivation, and embrace failures as learning opportunities.
