A couple of rules wishes make it practicable to apace find a area with a abrupt withdrawal of money. Beneficial forum posts. Thanks a lot! Information well regarded!. You made your stand extremely nicely.! Thanks, I enjoy it. You said this really well. Beneficial tips. Wonderful facts, Cheers! Thank you, Fantastic information! Thank you!
I value it! Appreciate it. The most excellently online casinos in Israel with unchain spins and no keep bonuses. This is nicely expressed! With thanks, I appreciate this! Wow a good deal of very good advice. The most excellently online casinos in Israel with free spins and no lodge bonuses. Useful data. You definitely made your point! Seriously quite a lot of good information. Truly lots of valuable knowledge.
You stated this superbly! If you arrive late, no worries! Around the resort, there are two pools for guests if there is a desire to get in the water right away! Snorkelling right outside the resort is also an option depending on conditions. Manta resort also offers a restaurant that serves local and western meals all day long.
Meals can be delivered to your room or you can sit at our seafront restaurant and enjoy the views of Mount Rinjani on Lombok. For divers, you can also order food before a dive to have it ready when you return! Managua is the larger of the two and can carry up to 30 divers, Samui is a bit smaller holding around During high tide, these boats are right outside the shop! During low tide, these boats are docked down the beach, about a 5-minute walk. Of course, the main reason you are here is for diving!
Manta runs at least two dives a day, one in the morning and one in the afternoon. During high season there is usually a noon dive as well. Dive sites we visit varies every day and what time of day. So, what should you expect while diving with us? The overriding desire to get the job allows for intentional response distortion on the assessment. Online selection processes such as online applications and pre-employment assessments or job screening are becoming more and more the norm Alessandri et al.
More and more applicants are prone to faking or response distortion on online pre-employment assessments Jensen et al. Faking and Response Distortion in Online Assessments One of the main problems facing the use of online assessments is that applicants are prone to distort their answers to online assessments to appear to be the perfect candidate for the position.
Basing personnel selections on response-distorted assessments not only cost organizations but also reduces the validity of the instrument.
Personality assessments are also not multi-cultural nor do they test for faking. Person-Environment Fit Pervin defined person-environment PE fit as the positive interaction among specific characteristics and personality traits of the employee and the environment, which promote higher job satisfaction, better performance, less work related stress, and can predict turnover intention. Previous research has focused on individual elements of PE fit, but employees interact with their co-workers, supervisors, and organization on a daily basis Tak, Person-job fit.
Person-organization fit. Person-organization fit is the conformity between the goals and values of both the organization and employee. Applicants attract to organizations with whom they share attributes and values that match. Person-group fit. Person-group fit is the compatibility between an employee and their immediate work group. This dimension of PE fit predicts the attraction of the employee to others similar to them in their social work environment.
Researchers have found that similarity can predict group behavior and that similar personalities among employees foster communication and social integration. Person-supervisor fit. Person-supervisor fit is the match between the employee and their supervisor in the work environment. Person-supervisor fit plays a role in job performance, job satisfaction, and turnover intention.
Shifting workforce demographics makes it hard for organizations to recruit and acquire the right mix of employees to meet the organization's strategic agenda. High turnover costs motivate organizations to find new ways to select personnel. Selection processes that seek to achieve higher levels of PE fit between new hires and the organization rely on effective communication. PE fit is harder to measure for since Woods and Bandura explain that we are both producers and products of our environments.
These organizational communications use logos, pictures, and music to communicate their values and beliefs to both internal and external audiences. It is through these communications that a prospective candidate measures the fit between their values and those of the organization. Another organizational strategy is to include accurate job descriptions via organizational communications outlining both positive and negative aspects of the job; the intention is to have applicants that feel themselves a poor fit for the job opt out before starting an application.
Once the hiring manager selects an applicant, the next step in the selection process is the face-to-face interview. Lost in the activity of the interview itself is the fact that the interview is an interaction between two people.
Each is giving and receiving information as the interview unfolds. Interviewers must be aware of the impression they give to potential applicants. Not only are interviews used to help select the best applicant, but the interviewer also has to be aware of the fact that applicants are collecting information about the organization.
This information will help inform their decision to accept the job or not. Organizations employ a battery of interview types to help mitigate personnel decisions. These are structured interviews, semi-structured interviews, and unstructured interviews Barrick et al.
Structured interviews focus on job-relevant information; which research has shown to provide more accurate results than semi- structured or unstructured interviews. There is a limit to the amount of structure one can impose on the interview process before it becomes cold, mechanical, and impersonal. At the onset of the interview, unstructured communication can help put the interviewee at ease and build rapport. Interview self-presentation is a set of behaviors used by individuals to communicate an identity to an audience.
Self-promotion, however, generates a general dislike in the interviewer Paulhus et al. Tactical- modesty is an alternative approach by the interviewee as a way to decrease the dislike generated by self-promotion or an advanced highly positive impression. Video Interviewing As technology advances, more and more organizations feel the pressure to reduce costs and improve efficiency in their HR approach to recruiting application collection and management, and preliminary screening via online assessments Sears et al.
Considering these demands, some organizations are moving away from traditional face- to-face interviews and toward video conferencing VC interviews Sears et al. There have emerged two types of VC, each with distinct attributes and advantages.
Leveraging new technology, such as live VC or VC on demand to build a sustained competitive advantage through human capital should become a focused HR strategy. Live Video Conferencing. LVC allows two parties to meet in a mock face-to-face environment; however, there can be a delay of audio and video due to compression.
LVC can lead to a less fluid conversation where each participant has to take turns to ask or answer questions. It also increases the amount of time any given participant speaks at one time. One of the main differences between LVC and face-to- face interviewing is the loss of non-verbal cues such as body language, eye contact, and handshaking.
Another difference is that only the upper torso of both participants is visible in VC. A restricted view of the participants reduces the perception of body language and can influence the decision-making process.
Video Conferencing on Demand. VC on demand differs from live VC in the fact that the interviewer is absent. The applicant records their answers to pre-recorded questions via webcam.
VC on demand gives personnel selection managers the freedom to view the interview whenever they want to create an on-demand platform. The interviews can be fast-forwarded, paused, replayed, or skipped altogether once the applicant disqualifies.
Managers can share interviews and can compare answers among different applicants to make the best hiring decision possible. Managers can review interviews more than once allowing them to discover information they missed the first time. Any organization moving away from traditional face-to-face interviewing and toward VC interviewing should go to great lengths to explain why to potential applicants. Although Toldi found VC interviewing to be favored by applicants, many people were unfamiliar with webcams and their operation.
Organizations should continue to use and develop VC technology, but as Sears et al. Along with online assessments and video interviewing, some organizations peruse the social media sites of their applicants to capture a more holistic view of them.
Individuals often share pictures, videos, music, blogs, personal interests, and demographic information such as marital status, sexual preference, religion, age, and ethnicity.
Since personal information is so readily available, employers have begun using social media websites to gain extra insight into their applicants Madera, Hiring managers feel the content on social media sites in a more honest representation of a prospective candidate. Whereas a candidate could have some different resumes for different jobs, they usually only have one social site, which more accurately reflects the real person.
Another reason hiring managers use social media sites to screen applicants is that they are efficient and highly cost effective. Once an applicant has progressed in the hiring process, HR managers can simply type the name of the applicant into search engines such as Google or Yahoo to collect additional information about the applicant. Applicant Internet searches have become a simplistic way to avoid negligent hiring issues. By searching for an applicant on the Internet, HR managers can find out if the applicant has any unreported criminal activity and, more importantly, if the applicant would pose a risk to themselves or others in the workplace.
Personnel selection researchers and practitioners are encouraged to look beyond traditional means of applicant data collection. Since there is a large and significant amount of data that falls outside of the functions of personnel selection available on social network sites, HR managers should use this information to their advantage and help make the best hiring decision possible.
The legality of using social networking sites to gather additional information is still up for debate, however. What is not up for debate is how adverse impact influences the hiring practices of organizations in the United States. Stemming from this legislation, the Federal Government developed the Uniform Guidelines of Employee Selection Procedures UGESP in to help organizations comply with using non- discriminatory tests and other selection procedures.
The burden of ensuring that employee selection processes and instruments pre-employment assessments are valid and reduce or eliminate adverse impact falls to the organization Arthur et al. The EEOC defines employment tests as cognitive tests, physical ability tests, sample job tasks, medical exams, personality tests, criminal background checks, credit checks, performance appraisals, and English proficiency tests EEOC, There have been some lawsuits against organizations both large and small for employing unethical hiring practices, violating Title VII see EEOC website.
Although Title VII forced assessment researchers to explore and create tests that were socially conscious and valid, there is no real way to eliminate adverse impact altogether. Transition Section 1 of this study provided an extensive description of personnel selection in casual dining restaurants and why it is important.
The background of the problem laid the foundation for the significance of the problem statement. The purpose statement and the nature of the study outlined the details of the study, including both the research method and design. The research question, participants, and methodology lent guidance for the study. Next, an assessment of the assumptions, limitations, and delimitations of the study was followed by the significance of the study.
The literature review represents an extensive review of existing literature on personnel selection in the casual dining restaurant industry allowing me to fully understand all facets of existing research and how it relates to the study topic. The literature review outlined past, present, and future approaches to personnel selection in the restaurant industry and how the industry continues to struggle with turnover.
Section 2 delineates the plan for how field research was conducted. Section 3 presents the findings after receiving approval of the proposal of the study. Moving to a person-environment fit could also reduce costs related to recruiting, selecting, training, and retaining employees, saving restaurants millions of dollars annually. I collected data from personnel selection managers in the casual dining sector using semi structured interviews.
I also collected data from company websites and company documents such as applications, screening assessments, and human resource policies on personnel selection strategies. Understanding the personnel selection strategies used in the casual dining restaurant industry may help develop a unique process or instrument that will help select employees who will create a sustainable competitive advantage.
Purpose Statement The purpose of this qualitative multiple case study was to explore the selection strategies restaurant managers use to select personnel. Not only does turnover equate to millions of dollars lost to organizations, but it also affects customer satisfaction in a negative way by undermining morale and job satisfaction in the industry.
The targeted population consisted of six casual dining restaurant managers in the central Georgia area. Exploring personnel selection strategies in casual dining restaurants will provide an opportunity for casual dining managers to understand and improve their personnel selection processes and strategies.
Recommendations from this study could help restaurant managers select personnel who better fit the restaurant environment and industry culture. These recommendations could not only improve job satisfaction among employees, but increase productivity, efficiency, and financial performance.
Role of the Researcher As a researcher, I was directly responsible for recruiting participants, collecting and coding data through semi structured interviews using open-ended questions designed to reveal the lived experiences and observations of the participants Chenail, With 15 years of experience in the casual dining sector, I interviewed managers from other restaurant concepts and chains whom I did not know and with whom I had never worked in order to avoid researcher bias Chenail, Although I have lived in the Central Georgia area for four years, I have only worked for one organization.
Interviews were recorded once the participants understood and agreed to the terms of the informed consent. All participants received ethical treatment as outlined in the Belmont Report Office for Human Research Protections, The Belmont Report provides guidance for researchers on how to be fair to all participants, how to do no harm, and how to maintain justice while conducting the research.
The Belmont Report details basic ethical principles that assist in resolving ethical problems during research with human subjects Office for Human Research Protections, Participants I randomly recruited six restaurant managers in the Macon and Warner Robins, Georgia, area.
I contacted all participants in person or by telephone, and all interviews were conducted in public settings. I explained the nature and structure of the study to the participants, along with the informed consent.
The participants and I agreed to a date, time, and location for the interview. The participant size was set at six to ensure adequate data to analyze and synthesize and to achieve data saturation Suri, I provided all six participants with a consent form for them to sign before interviewing.
Research Method and Design Research Method Since the focus of this study was to explore what types of personnel selection strategies restaurant managers use, a qualitative method was appropriate. The qualitative methodology allowed me to observe, examine, explore, and investigate the phenomena under study in the natural setting without disrupting operations Hanson et al.
A qualitative approach allowed a more flexible exploration of other factors that influence personnel selection decisions. A qualitative approach is very adaptable. Quantitative research is the investigation of the statistical significance among variables without fully considering the relationship among said variables.
Since the primary goal of this study was to examine the personnel selection strategies used by restaurant managers, which included a more subjective approach when screening applicants, a quantitative method would not reveal the phenomena in its true form. Although a quantitative approach could prove useful in understanding the relationship of the costs of training and turnover in an organization to personnel selection styles, a qualitative method allows the researcher to explore the process and criteria used during the selection process.
A qualitative approach allowed these to rise to the surface for examination. Research Design The focus of this multiple case study was to understand the personnel selection strategies used by restaurant managers. Through the collection of descriptive data, the researcher can apply analysis to uncover the essence of the phenomena Petty et al. Before deciding on applying a multiple case study design to the research, I evaluated other designs, such as phenomenology, grounded theory, narrative, and ethnography.
I compared theses designs against their ability to elucidate the problem, the research, and the project. A phenomenological approach was not appropriate since it focuses on how individuals experience a particular phenomenon and how it influences their lived experiences; this approach is not effective in exploring a personnel selection strategies singular event or group Hanson et al. With this study, I examined the strategies, external and internal, used by a diverse group, each with differing organizational goals.
Grounded theory aims to generate a theory based on the data collected from the participants who experienced the phenomena Petty et al. Organizations have to hire employees. I sought to explore the strategies used by restaurant managers and why they employed those strategies.
A narrative approach would only provide data from participants who experienced a single event Petty et al. Personnel selection is a continuous process where diverse variables interact, creating a phenomenon that will resonate throughout the environment. Ethnography focuses on the shared patterns of behavior, beliefs, and language in a cultural group Petty et al. Although restaurant managers are a distinct group, it was precisely the differences between their beliefs and behaviors regarding their use or non-use of personnel selection strategies that I wished to understand.
Population and Sampling The sample for this study consisted of casual dining managers directly involved in the selection of employees for their business. Sample sizes for qualitative research must be practical in the sense that the sample size is both accessible and addressed the research question Robinson, For this study, I randomly selected six managers of casual dining restaurants responsible for the screening, interviewing, and hiring of personnel.
Purposeful sampling of six experienced personnel managers contributed to a deeper understanding of the phenomenon Petty et al.
My industry experience provided the baseline for data saturation. I was able to determine when the incoming data had become repetitive and static. I believe that six casual dining restaurant managers, three who used e-based strategies and three who used intuition-based strategies, provided data saturation for this study.
My experience of working 15 years in casual dining restaurants influenced participant selection. Due to my experience, I was able to identify and access restaurant personnel managers, gain their trust by demonstrating my understanding of restaurant operations and staffing, and elicit their uninhibited participation.
Interviewing participants of similar backgrounds, three who use some pre-employment assessment and three who do not, combined with my experience with both processes, enabled me to identify a saturation point for each group Petty et al. To ensure confidentiality and encourage open and honest responses, the participant chose the time and place for the interview.
Each interview session lasted between 30 and 45 minutes. Ethical Research Before conducting the study, I received written permission from the Walden IRB to conduct the research indicating the research would adhere to ethical guidelines. Data gathering did not commence until the participants signed the consent form.
All participants received ethical treatment as outlined in the Belmont Report Office for Human Research Protections, I then informed the participants verbally and via the consent form that participation was voluntary and that there was no incentive or compensation for their participation. It was important to establish purpose, consent, and confidentiality early on in the research process to put participants at ease and encourage their full engagement in the interview Rabionet, Since their participation was voluntary, they could withdraw from the interview either by contacting me through my personal e-mail, cell phone, or anytime during the interview itself.
I included all my personal contact information on each correspondence with the participants. There was no possibility of the participants encountering harm from their participation in the study. The study focused on personnel selection strategies in the restaurant industry, and the participants did not express personal or professional uneasiness regarding the subject matter.
To maintain complete confidentiality, I am the only one with knowledge of the participants and their responses. All electronic media or documentation gathered or created in the process of conducting the research remains in a locked location and will be destroyed after five years. Data Collection Instruments Data collection for this study was through semistructured, face-to-face interviews conducted with managers of casual dining restaurants.
Interview questions are in Appendix A. The interview has become the main data collection tool for qualitative research Englander, Using open-ended questions allows the participants a chance to reflect on their lived experiences and provide detailed responses. A semi-structured interview framework fits with the research design allowing for an investigation with follow-up questions, which provided a deeper understanding of the diverse, lived experiences of casual restaurant managers and their strategies for personnel selection Englander, By using face-to-face interviews, I was able to capture and record the nuance of participant body language.
To ensure accuracy, I recorded the interviews, transcribed them using MAXQDA software, and then sent them to the respective participants for validation of the accuracy of the interview Hanson et al.
To ensure internal and external validity, I used triangulation and transcript review Hanson et al. Data Collection Technique I collected all the data required for this research. Data collection came from face- to-face semi-structured interviews with casual dining restaurant managers. It is important during the interview to establish a rapport with the participant, creating a safe space where they can truthfully share their experiences, observations, and stories Rabionet, I scheduled the interviews for a date, time, and location that work for both the participant and me.
The interviews took place in public locations of the participants choosing. The interviews lasted approximately minutes. The interview questions are in Appendix A. In addition to the semi-structured interviews, I enhanced the interview data with company records on recruiting paraphernalia such as company websites, recruiting pamphlets, and any literature given to prospective applicants. A main principal of case study design is to collect data from two or more sources, which confirm the data collected and the findings Yin, During the interview, I used open-ended questions.
Open- ended questions are flexible enough to allow the participant fully to express their experiences Rabionet, The participants in this study are personnel managers directly responsible for the selection and hiring of restaurant employees.
Before the interview, I ensured the recording device was working properly. Some things can affect the interview, the quality of the recording equipment, the setting regarding background noise and comfort, interviewee gender, and the familiarity among interviewer and interviewee Rabionet, I provided the participants with an overview of the research and explained the informed consent form to them.
Once the participants returned the signed informed consent form signaling their voluntary participation, I scheduled a place and time for the interview. At the beginning of the interview, I reiterated the informed consent and that the participant can opt-out of the research at any time. However, after initially conducting an analysis of the data, I returned the analyzed interviews to the participants for member checking as recommended by Mero-Jaffe By returning the transcripts to the interviewees will not only help validate the transcript, but allow for discussions and further data collection around the clarity of issues, themes, or specific comments Mero-Jaffe, For this study, I used alphanumeric codes to conceal the identities of the participants.
Through informed consent, I ensured that the participants knew that I would be recording the interviews. I assigned each participant a number starting at one preceded by the letter M for the manager. I used MAXQDA software to input and store interview data for coding and identifying emerging themes while maintaining confidentiality and anonymity for the participants. According to Fein and Kuilk , a way to safeguard confidentiality is to limit access to the data.
In that regard, all computer data including transcribed interviews, notes, codes, and themes are stored on a password protected flash drive and secured in a locked container, along with any handwritten field notes or observations, for five years. After the five-year period, I will destroy the data by shredding hand written notes and erasing the flash drive.
Data Analysis Qualitative research allows the researcher to use open-ended questions to gather data, identify themes, and explore the meaning of themes within the structure of the study Rabionet, PROCESS : Here, data scientists take the prepared data and probe its ranges, patterns, and biases to find how beneficial it'll be in predictive analysis. In this phase, the activities include data reporting, Business Intelligence BI , data visualization, and decision-making.
Requirements for Data Science Here are a few technical concepts you should know before starting to learn what data science is. Machine Learning ML : ML is the backbone of data science; hence, data scientists must have a strong understanding of the topic.
Modeling : Mathematical models allow us to make quick calculations and predictions based on what we know about the data. Modeling is also a part of ML and involves finding which algorithm is most suitable for solving the given issue and how to train these models.
Statistics : It's the core of data science, where a sturdy handle on statistics helps you extract more intelligence and acquire meaningful insights. Programming : Some level of programming is needed to perform a successful data science project. The most common languages are Python and R. Databases : A potential data scientist requires to learn how databases operate, how to manage them, and how to extract data from them. Roles of Data Scientists Data scientists are the most recent analytical data experts who have the technical potential to tackle complex problems and the desire to probe what questions require to be answered.
Some of the daily routine activities or tasks for a data scientists include: Identify patterns and trends in datasets to get insights Enhance data quality by leveraging ML techniques Leverage data tools like SQL, R, SAS, or Python for data analysis Create forecasting algorithms and data model Other than these daily tasks, a data scientist also solves business issues through a series of procedures, including: Before handling the data collection and analysis, the data scientist identifies the issue by asking the right questions and meaningful insights.
They then determine the accurate data and variable sets. The scientists then collect unstructured and structured data from several disparate sources such as public data, enterprise data, and more. Once the data is collected, they process the raw information and convert it into a suitable format for analysis. Once the data is rendered, it's fed into the analytic system, i.
This is where the scientists analyze and determine trends and patterns. When the data is completely rendered, they interpret the data to identify opportunities and solutions.
They complete the task by preparing the outcomes and insights to share with suitable stakeholders and communicating the results.

Top 10 Machine Learning Algorithms 1. Linear Regression This process establishes the relationship between dependent and independent variables by fitting them to a line.
Logistic Regression This process estimates the discrete values from an independent variable set. Decision Tree This is one of the widely popular and used algorithms of Machine learning.
Support Vector Machine SVM This process is used to classify algorithms in which you plot raw data as points in an n-dimensional space. K-Nearest Neighbors KNN KNN is a more widely leveraged algorithm to solve classification problems; however, this technique can also be applied to regression problems. K-Means K-Means is an unsupervised learning algorithm that solves clustering problems.
The K-Means algorithm picks the 'k' number of points known as centroid for each cluster. Each data point forms a cluster with the nearest centroids K clusters Now, it creates new centroids based on the existing cluster members.
The nearest distance for each data point is estimated with the new centroids. This process continues until the centroids don't change. Random Forest Algorithm A collective of decision trees is known as a Random Forest, which is leveraged to classify a new object based on its attributes, where each tree is classified, and the tree votes for that class. If the number of cases is 'N' in the training set, the sample of N cases is taken randomly. This sample will be the training set for tree growing.
The value of 'm' is held constant during this process. Each tree is grown to the most substantial extent possible, and there's no pruning.
Dimensionality Reduction In the modern world, a massive amount of data is being analyzed and stored by govt agencies, research organizations, and corporates.
