Operational Characteristics of Filtering Partitions from Wire Grids with Cells of Micron Sizes

Published: January 2014

Results of pilot studies related to hydraulic resistance of wire woven grids with cells of micron sizes in laminar mode of a filtration have been presented. For assessment of grids hydraulic resistance the permeability coefficient value has been used. To overcome the effect of a large-scale factor on conducted researches results the dimensionless size of this parameter in the form of permeability coefficient relation to a square of the grid cell size is entered. The researches have been conducted on free-flow hydraulic installation by specially developed technique providing high precision determination of this parameter. Influence like wires interlacing at a size of dimensionless coefficient of permeability is established. Nature of influence like wires interlacing at a size of this parameter is confirmed with results of wire grids internal structure analysis. On the basis of obtained data the choice technique like grid has been developed for production of a filtering partition with optimum characteristics at the set size of filtering nominal subtlety. On the basis of porous body channel model the assessment of hydraulic resistance coefficient value of wire grids with various type of wires interlacing has been carried out. Dependence of this parameter on wires interlacing type has been established. Groundlessness of interstice’s tortuosity coefficient use at assessment of grids hydraulic resistance has been shown.
Modeling Indivisible Demand
Authors: Lee Sanghak , Allenby Greg M.
Published: January 2014

Disaggregate demand in the marketplace exists on a grid determined by the package sizes offered by manufacturers and retailers. Although consumers may want to purchase a continuous-valued amount of a product, realized purchases are constrained by available packages. This constraint might not be problematic for high-volume demand, but it is potentially troubling when demand is small. Despite the prevalence of packaging constraints on choice, economic models of choice have been slow to deal with their effects on parameter estimates and policy implications. In this paper we propose a general framework for dealing with indivisible demand in economic models of choice, and we show how to estimate model parameters using Bayesian methods. Analyses of simulated data and a scanner-panel data set of yogurt purchases indicate that ignoring packaging constraints can bias parameter estimates and measures of model fit, which results in the inaccurate measures of metrics such as price elasticity and compensating value. We also show that a portion of nonpurchase in the data (e.g., 2.27% for Yoplait Original) reflects the restriction of indivisibility, not the lack of preference. The importance of demand indivisibility is also highlighted by the counterfactual study where the removal of the smallest package size (i.e., 4 oz) mainly results in nonpurchase in the yogurt category instead of switching to larger package sizes.
Analyzing Moment-to-Moment Data Using a Bayesian Functional Linear Model: Application to TV Show Pilot Testing
Authors: Hui Sam K. , Meyvis Tom , Assael Henry
Published: January 2014

Researchers often collect continuous consumer feedback (moment-to-moment, or MTM, data) to understand how consumers respond to a variety of experiences (e.g., viewing a TV show, undergoing a colonoscopy). Analyzing how MTM judgments are integrated into overall evaluations allows researchers to determine how the structure of an experience influences consumers' post-experience satisfaction. However, this analysis is challenging because of the functional nature of MTM data. As such, previous research has typically been limited to identifying the influence of heuristics, such as relying on the average intensity, peak, and ending.

We develop a Bayesian functional linear model to study how the different “moments” in the MTM data contribute to the overall judgment. Our approach incorporates a (temporally) weighted average of MTM data as well as specific “patterns” such as peak and trough, thus nesting previous approaches such as the “peak-end” rule as special cases. We apply our methodology to analyze data on TV show pilots collected by CBS. Our results reveal several interesting empirical findings. First, the last quintile of a TV show is weighted about four times as much as each of the first four quintiles. Second, patterns such as peak and trough do not play substantial roles in driving overall evaluations for TV shows. Finally, the last quintile is more important for procedural dramas than for serial dramas. We discuss the managerial implications of our results and other potential applications of our general methodology.
B-Type Natriuretic Peptide Forms within the Heart, Coronary Sinus, and Peripheral Circulation in Humans: Evidence for Degradation before Secretion
Authors: Mahagamasekera Patalee G , Ruygrok Peter N , Palmer Suetonia C , Richards A Mark , Ansell Gareth S , Nicholls M Gary , Pemberton Christopher J , Lewis Lynley K , Yandle Timothy G
Published: January 2014

BACKGROUND

The B-type natriuretic peptides (BNP and N-terminal pro-BNP) are secreted by the heart and, in the case of BNP, serve to maintain circulatory homeostasis through renal and vascular actions and oppose many effects of the renin-angiotensin system. Recent evidence suggests that in patients with severe heart failure, circulating immunoreactive BNP is made up mainly of metabolites that may have reduced bioactivity. We hypothesized that BNP may be degraded before it even leaves the heart.

METHODS

Peripheral venous plasma plus atrial and ventricular tissue, obtained from explanted hearts at the time of transplantation, were collected from 3 patients with end-stage heart failure. In a separate study, plasma was collected from the coronary sinus and femoral artery of 3 separate patients undergoing cardiac catheterization. Plasma C18 reverse-phase extracts were separated on reverse-phase HPLC, and the collected fractions were subjected to RIAs with highly specific antisera directed to the amino- and carboxy-terminal ends of BNP(1–32).

RESULTS

ProBNP, BNP(1–32), and 2 major BNP metabolites were present in atrial and ventricular tissue, where BNP(1–32) represented 45% and 70% of total processed BNP, respectively. Neither BNP(1–32) nor the 2 metabolites were detected in peripheral venous plasma. Nor was BNP(1–32) detected in matching coronary sinus and femoral artery plasma from the 3 patients undergoing cardiac catheterization.

CONCLUSIONS

BNP(1–32) is partly degraded within the hearts of patients with end-stage heart failure, and even in patients with relatively well-preserved left ventricular systolic function, only BNP metabolites enter the systemic circulation.
Noninvasive Micromarkers
Authors: Saikumar Janani , Ramachandran Krithika , Vaidya Vishal S
Published: January 2014

BACKGROUND

The recent revolutionary advances made in genome-wide sequencing technology have transformed biology and molecular diagnostics, allowing new sRNA (small RNA) classes to be discovered as potential disease-specific biological indicators. Cell-free microRNAs (miRNAs) have been shown to exist stably in a wide spectrum of body fluids and their expression profiles have been shown to reflect an assortment of physiological conditions, underscoring the utility of this new class of molecules to function as noninvasive biomarkers of disease.

CONTENT

We summarize information on the known mechanisms of miRNA protection and release into extracellular space and compile the current literature on extracellular miRNAs that have been investigated as biomarkers of 20 different cancers, 11 organ damage conditions and 10 diverse disease states. We also discuss the various strategies involved in the miRNA biomarker discovery workflow and provide a critical opinion on the impediments faced by this advancing field that need to be overcome in the laboratory.

The field of miRNA-centered diagnostics is still in its infancy, and basic questions with regard to the exact role of miRNAs in the pathophysiology of diseases, and the mechanisms of their release from affected cells into biological fluids are yet to be completely understood. Nevertheless, these noninvasive micromarkers have immense potential in translational medicine not only for use in monitoring the efficacy and safety of therapeutic regimens but also to guide the diagnosis of diseases, to determine the risk of developing diseases or conditions, and more importantly, to inform treatment options.

La reorientación del ciclo de vida del área turística. El caso de Bahías de Huatulco, Oaxaca (México).
Authors: López Guevara Víctor Manuel
Published: January 2014

La publicación del modelo de Richard Butler (1980) referente al Ciclo de Vida del Área Turística (CVAT) ha generado un debate permanente en torno a la evolución de los destinos vacacionales. Con base en la revisión de diversos estudios que contrastan y cuestionan la validez del CVAT, en este trabajo se formula un esquema alternativo de análisis mediante el cual se realiza el diagnóstico de las fases de desarrollo y situación actual de un centro planificado de turismo litoral ubicado en la costa sur de México: Bahías de Huatulco.A través del caso de estudio se evidencia la pertinencia del modelo propuesto, se determina que el centro turístico en cuestión _aún cuando no ha alcanzado su máximo grado de desarrollo_, se encuentra en medio de una fase de reorientación y se anota una serie de propuestas para revitalizar la actividad turística.The publication of Richard Butler’s Touristic Area Life Cycle model (TALC) in 1980 led to an intensive and ongoing discussion regarding development of tourist destinations. On the basis of some major subsequent studies which question the validity of the TALC, this thesis will look into an alternative model. This is done by identifying and analyzing the current situation as well as different stages of development of a planned tourism destination located in the coastal region of southern Mexico: Bays of Huatulco.The case study demonstrates the appropriateness of the proposed model. Furthermore, it is shown that the analyzed region Bays of Huatulco has not yet reached its maximum degree of development and is currently on the so-called ‘reorientation’ stage. Some further recommendations to revitalize the tourism activity in this tourism resort are also provided.

For the design of modified atmosphere packaging, it is necessary to know the influence of time and temperature on the respiration rate (RR) of fresh produce. RR of fresh fig and diced papaya was measured at three temperatures (10, 20 and 30°C) for storage time of 1–5 days under aerobic condition using closed system method. The aim was to determine the influences of storage temperature and time on RR of fresh fig and diced papaya. It develops and validates a combined predictive mathematical model based on the Arrhenius equation and Weibull distribution model. Temperature and time had a significant effect on RR. of fresh fig and diced papaya ranged from 16.2 to 45 and 25.5 to 114.9 ml kg–1 h–1 and ranged from 11.5 to 51.9 and 23.9 to 113 ml kg–1 h–1, respectively, over the three storage temperatures tested. RR increased significantly four- to fivefolds with increase in temperature from 10 to 30°C. Temperature and the interaction of time and temperature had the significant effect on and . Arrhenius and Weibull distribution models successfully fitted the experimental data, adequately describing the influence of temperature and time on RR of fresh fig and diced papaya. This model can be used to predict RR at different temperature and time. The model which was tested at 15°C for its validity showed good agreement between experimental and predicted data. These models would help to choose the optimum packaging for selected fruits.

Published: January 2014

Aim: To determine the factors affecting neonatal prognosis in preterm premature rupture of membranes (PPROM).

Method: We conducted a case-control study involving 92 women between the years 2000 and 2010 diagnosed with PPROM between 25 and 31 weeks’ gestation, who received antenatal steroids, and delivered between 26 and 31 weeks’ gestation; a retrospective cohort study was conducted based on the results. We used data from four tertiary centers and compared the frequencies of neonatal neurologic deficits and neonatal deaths.

Results: There was a difference between the two groups; specifically, the ND group (n=18) consisted of patients whose infants had neurologic deficits and/or neonatal deaths and the neurologically normal (NN) group (n=74) included NN neonates amongst the patients who had expectant management (94% vs. 73%, respectively). Multivariable analysis revealed that expectant management was independently associated with an increased risk for neonatal neurologic deficits and neonatal deaths (odds ratio, 16.14). All neonates with poor prognosis in the expectant-management group delivered within 14 days after PPROM.

Conclusions: Expectant management within 14 days after PPROM is associated with poor neonatal outcomes. Decisions regarding an expectant strategy should be made carefully. An immediate, planned delivery after steroid administration should be considered to improve neonatal prognosis in patients who have PPROM after 26 weeks’ gestation.
The Desire to Return during Civil War: Evidence for Internally Displaced Populations in Colombia
Authors: Arias María Alejandra , Ibáñez Ana María , Querubin Pablo
Published: January 2014

Armed conflict in Colombia has forcibly displaced more than 3.6 million people. In a post-conflict scenario, the socioeconomic stabilization of displaced households is crucial, as families must decide whether to stay in the reception place, relocate to a new municipality or return to their site of origin. In this paper we identify the determinants of the desire to return of internally displaced households in Colombia. We find that i) land tenure in the place of origin provides an incentive to return; ii) vulnerable households, in particular female-headed households and those from ethnic minorities seek to establish themselves at the reception site and exhibit a lower desire to return; iii) those who displaced as a consequence of a direct attack are less willing to return; iv) economic opportunities in the place of origin encourage return while economic opportunities at the reception site decrease the willingness to return; and v) social networks, as exemplified by membership in peasant organizations and collective land ownership, increase the desire to return. To be successful, the design of stabilization programs for the displaced population must consider these particularities of the households that are willing to return and those who prefer to stay in the reception site.

Authors: Demircan Ozgur , Ashibe Shinsuke , Kosui Tatsuya , Nakai Asami
Published: January 2014

Within the scope of experiments, the effect of aramid and glass yarns as stitch and biaxial (warp and weft) yarns in the biaxial weft knitted (BWK) composite was compared. After production of four types of composite panel using the hand lay-up method, the tensile and bending properties of the BWK composites were investigated both experimentally and numerically. The composite with the glass stitch and biaxial yarns exhibited higher tensile and bending properties than did the composite with the aramid stitch and biaxial yarns. The good agreement between the experimental results and the numerical results validated the applicability of the finite-element method for the BWK composites. The laminate beam theory was utilized as another modeling method for calculation of the bending modulus.
New Borate Structures for Nlo Applications
Authors: Keszler Douglas A. , Akella Annapoorna , Schaffers Kathleen I. , Alekel Theodore
Published: January 2014

By considering selected examples of new structure types, guidelines are set forth for the synthesis of new solid-state inorganic borates that are likely to have desirable properties for nonlinear optical applications. The structures of two new, noncentrosymmetric orthoborate fluorides BaCaBO3F and Ba7(BO3)3F5 demonstrate a feasibility for controlling linear optical properties and for producing noncentrosymmetric borates that melt congruently. The structure of SrLi(B3O5)3 represents an additional example of a noncentrosymmetric borate resulting from chirality of the B3O7 ring. In addition to potential practical value, crystals of the type AMOB2O5 (A = K, Rb, and Cs; M = Nb and Ta) provide a unique means for examining the structural dependent interrelationships of linear and nonlinear optical properties.

Complex systems science provides a transdisciplinary framework to study systems characterized by (1) heterogeneity, (2) hierarchy, (3) self‐organization, (4) openness, (5) adaptation, (6) memory, (7) non‐linearity, and (8) uncertainty. Complex systems thinking has inspired both theory and applied strategies for improving ecosystem resilience and adaptability, but applications in forest ecology and management are just beginning to emerge. We review the properties of complex systems using four well‐studied forest biomes (temperate, boreal, tropical and Mediterranean) as examples. The lens of complex systems science yields insights into facets of forest structure and dynamics that facilitate comparisons among ecosystems. These biomes share the main properties of complex systems but differ in specific ecological properties, disturbance regimes, and human uses. We show how this approach can help forest scientists and managers to conceptualize forests as integrated social‐ecological systems and provide concrete examples of how to manage forests as complex adaptive systems.
Neonatal Skin and Chlorhexidine: A Burning Experience
Authors: Kutsch Jennifer , Ottinger Daniele
Published: January 2014

Purpose: Despite the lack of safety data, chlorhexidine gluconate (CHG) is an antiseptic with broad-spectrum coverage often used in neonatal intensive care units (NICUs). Adverse skin reactions, most commonly burns, have been reported after the use of CHG. Preserving skin integrity in preterm infants is vital in the prevention of sepsis, excessive water loss, hypothermia, and renal failure.

Design: This is a case report of two incidents of significant skin burning in extremely low birth weight (ELBW) infants who were treated with CHG for the purposes of umbilical cord sterilization prior to umbilical line placement.

Sample: This case report of burns associated with CHG in one infant weighing 610 g at birth and a second infant weighing 600 g at birth.

Results: CHG does have a strong association with causing skin burns in the ELBW population; however, wiping the solution off of the skin seems to reduce injury.

Cities in transcontinental context: A comparison of mega urban projects in Shanghai and Belgrade
Authors: Waley Paul
Published: January 2014

This study of urban developments in Belgrade and Shanghai is set in the
context of comparative urban research. It presents two ostensibly contrasting
cities and briefly examines urban development patterns in China and Serbia
before focusing more specifically on mega urban projects in the two cities -
Pudong and Hongqiao in Shanghai contrasted with New Belgrade. While the
historical genesis of the Chinese and Serbian projects differs markedly,
together they provide complementary examples of contemporary entrepreneurial
urban development in divergent settings. China and Serbia share a heritage of
state ownership of urban land, and this characteristic is still very much a
feature underpinning development in Shanghai and other Chinese cities, as
well as in New Belgrade. In both territories, state ownership of land has
contributed to a form of urban development which - it is argued in this paper
- can best be seen as state-based but market-led. The comparative study that
this work initiates will, it is hoped, contribute to an understanding of
contextual change in the two worlds regions of East Europe and East Asia.
Strategic spatial planning in the era of crisis: Current trends and evidence from the metropolitan area of Thessaloniki
Authors: Thoidou Elisavet
Published: January 2014

Strategic spatial planning has enjoyed widespread implementation since the
1990s, especially in urban and metropolitan areas, having its focus on
promoting their competitiveness and sustainability. Nowadays, the effects of
economic crisis, together with growing environmental and technological risks,
trigger the vulnerability of these areas and stress the need for resilience.
This paper examines the role of strategic spatial planning in promoting
metropolitan resilience in the era of crisis. It is argued that this type of
planning is capable of supporting the adaptation of territorial systems to
crisis-induced risks, as is, for instance, the case of planning for climate
change. This is further analyzed in light of four of the key aspects of the
new strategic spatial planning, namely its principles, content, process, and
utilization of resources. The paper draws evidence from the case of Greece
and examines the abovementioned aspects of the recently prepared new
Regulatory Plan for the Thessaloniki greater area. The first results of this
examination show that, provided there is political will which allows for
necessary adjustments, the Plan has the potential to incorporate the
dimension of resilience. The elaboration and exploitation of the strategic
nature of the Plan and of its sustainable development principle constitute
key elements of a resilience-oriented approach.

Published: January 2014

Tourist events represent not only a significant tourism potential, but also
the touristic product of Serbia. There are approximately 2500 events every
year, attended by several million visitors from Serbia and all around the
world. Since the 1990s in the world and since the beginning of the 21st
century in Serbia, the organization and development of events has become a
significantly profitable activity. Certain countries developed event tourism
strategies on the level of the country or on the regional level; in Serbia,
the event tourism is mentioned in the national tourism development strategies
and certain regional ones. This paper targets the need for development of
Event Tourism Strategy on the level of Serbia.
Understanding Compliance with Bring Your Own Device Policies Utilizing Protection Motivation Theory: Bridging the Intention-Behavior Gap
Authors: Crossler Robert E. , Long James H. , Loraas Tina M. , Trinkle Brad S.
Published: January 2014

The purpose of this study is to examine the factors that determine whether employees follow Bring Your Own Device (BYOD) policies through the lens of the Protection Motivation Theory. BYOD is rapidly becoming the norm rather than the exception. As a result, firms are establishing BYOD policies to address the risk inherent in allowing individuals to use their own devices to access or store company data. This paper reports the results of a survey of accounting students, non-accounting students, and full-time employees. Results demonstrate that participants' intentions to comply with a BYOD policy were primarily motivated by Self Efficacy and Response Efficacy. Further, Threat Severity was more salient for accountants than non-accountants, perhaps due to their sensitivity to confidential data. Finally, when actual compliance behavior was considered, costs to comply were much more salient to employees and could be strong deterrents to full compliance. These findings have important theoretical and practical implications.
Speech Emotion Recognition Based on Sparse Representation
Authors: Yan Jingjie , Wang Xiaolan , Gu Weiyi , Ma LiLi
Published: January 2014

Speech emotion recognition is deemed to be a meaningful and intractable issue among a number of do- mains comprising sentiment analysis, computer science, pedagogy, and so on. In this study, we investigate speech emotion recognition based on sparse partial least squares regression (SPLSR) approach in depth. We make use of the sparse partial least squares regression method to implement the feature selection and dimensionality reduction on the whole acquired speech emotion features. By the means of exploiting the SPLSR method, the component parts of those redundant and meaningless speech emotion features are lessened to zero while those serviceable and informative speech emotion features are maintained and selected to the following classification step. A number of tests on Berlin database reveal that the recogni- tion rate of the SPLSR method can reach up to 79.23% and is superior to other compared dimensionality reduction methods.
Selection of Sound Insulating Elements in Hydraulic Excavators Based Onidentification of Vibroacoustic Energy Propagation Paths
Authors: Dąbrowski Zbigniew , Dziurdź Jacek , Pakowski Radosław
Published: January 2014

In spite of the fact that standardizing operations and increased awareness of hazards led to a significant improvement of vibroacoustic climate of operator’s stands of new machines, their long-term operation - often under difficult conditions - leads to a fast degradation of acoustic qualities of machines. Temporary operations performed during surveys and periodical overhauls are rarely effective, due to the lack of any guidelines. In this situation the authors propose the algorithm for selection of eventual screens or sound absorbing and sound insulating partitions, utilizing the measuring procedure aimed at identification, at the operator’s stand, of main noise components originated from various sources. On the basis of this procedure, the vibroacoustic energy propagation paths in the machine was estimated.
Awareness of Noise Hazards and the Value of Soundscapes in Polish National Parks
Authors: Bernat Sebastian
Published: January 2014

The goal of the studies undertaken in Polish national parks was to determine noise threats, examine the resources, assess the quality of soundscapes and identify the possibilities of their protection. The questionnaire method used in the studies made it possible to identify the awareness of noise threats and the value of soundscapes according to the park service staff. In addition, the semantic differential and description methods were used to learn how students assessed the soundscape quality of Polish national parks. Finally, avenues of further research on soundscape in environmentally valuable areas were indicated. The research findings indicate that each national park in Poland is characterised by diverse and unique soundscapes and is subject to the pressure of road traffic and tourism resulting in noise hazards. The conservation of the acoustic values of parks is necessary and possible.
Indicator of Vibroacoustic Energy Propagation as a Selection Criterion of Design Solution
Authors: Klekot Grzegorz
Published: January 2014

Contemporary tools which help to design technical objects refer to the conclusions drawn from studying the changes of physical processes accompanying the exploitation, especially to vibroacoustic processes. The main problem is to define such vibroacoustic measures, where their changes would model the analyzed physical phenomena in the best way. Basing on simple indicators which refer to occurring phenomena, it is possible to obtain accurate solutions with a satisfactory reliance level without using complex computing techniques needing detailed descriptors. According to the author, the indicators which are based on the analysis of vibroacoustic energy propagation are very useful in solving engineering problems. These indicators are useful while diagnosing the condition of technical systems, identifying and minimizing the vibroacoustic risks. The possibilities of using such indicators in order to find design solution are illustrated by sample results of the research of the structures with vibroacoustic elements which reduce the noise of rail vehicles by the rail vibration damping.
Technical Note. An Objective and Subjective Study of Noise Exposure within the Frequency Range from 10 kHz to 40 kHz
Authors: Smagowska Bożena
Published: January 2014

The paper consists of study results of exposure to high frequency noise at metalworking workplaces. The study was carried out using objective methods (measurements of parameters characterizing the noise) and subjective studies (questionnaire survey). Metalworking workplaces were located in a steel structure (e.g. deck gratings) of the manufacturing plant. The results are equivalent sound pressure levels in the 1/3 octave frequency bands with center frequencies from 10 kHz to 40 kHz in reference to an 8-hour workday equal to approximately 81-105 dB at most of the tested workplaces and exceed permissible values. The questionnaire survey of annoyance high frequency noise (i.e. in the audible frequency and low ultrasound range) was conducted among 52 operators of machines. Most of the workers describe the noise as: buzzing, insistent, whistling and high-pitched squeaky. Respondents specify the noise levels occurring at workplaces as: loud, impeding communication, highly strenuous and tiring.

Sport in International Relations. Expectations, Possibilities and Effects
Authors: Kobierecki Michał Marcin
Published: January 2014

The aim of this article is to show how sport can matter in international relations. Sport can be a subject or a tool of international relations. It can be used by states or geopolitical blocks to display their alleged superiority or any other desired characteristic. Governments may desire athletic victories, which are meant to imply, for example, the power of the state and its political and economic system. Participation in sport can also be used for political reasons on an international scale; a number of political objectives can be achieved by states by participating (or not) in sports events. Not only is sport affected by a country’s policies, but on certain occasions sports events can influence states.

Authors: Sarkar Shulagna
Published: January 2014

Training is a usual formula for organisations through which employees are introduced to learning, but the challenge lies in identifying the appropriate training needs of employees. The success of a training program depends primarily on the need assessment. The paper discusses the process of competency mapping and focuses on how competency mapping can be used for conducting training need assessment. The paper is an empirical research based on both public and private manufacturing units in India. Primary and secondary data was collected using number of techniques. Gap analysis has been performed for employees and it has also been aimed to verify the changes in competency gaps on applying need based training. On providing need based training, significant difference was measured in the level of competencies of employees. The paper shares a practical insight on the implementation of competency mapping for training need analysis. The research is focused on manufacturing units only, whereas there is a huge scope for it to be implemented in service industries also. The paper is an original piece of research where a model has been designed to resolve training issues of manufacturing industries.
A Review of Critical Success Factors for Offshore Software Development Projects
Authors: Sudhakar Goparaju Purna
Published: January 2014

Offshore project success is very much important to both customer and the vendor. Based on very less success rate of overall software projects globally, critical success factors (CSFs) for offshore software projects is gaining much importance. In the current study based on literature review, a total of 75 success factors for offshore software projects are identified. Further based on their appearance in literature 20 critical success factors from 10 CSF categories are identified. Finally top six most critical success factors for offshore software projects such as trust, efficient communication, cultural understanding, relationship between client and vendor, contract type and efficient knowledge transfer are identified. The CSFs categories are prioritized in the order of importance. The important CSF categories for offshore projects found are organizational factors (both client and vendor), project factors, cultural factors and environmental factors.
