Discussion: Authentic Leadership and Team Leadership

Discussion: Authentic Leadership and Team Leadership
Authentic Leadership is a relatively new leadership approach and as a result much more research is needed. There is no standard, accepted definition of Authentic Leadership but it can best be described as transparent, responsible to people’s needs, and adhering to a moral code. It is becoming more popular as a response to leadership failures in both the private and public sectors.

Teams have become more of a fixture in both the public and private sectors, and as a result, there is a greater interest in Team Leadership. Team Leadership posits that the critical function of leadership is to oversee the group, identify the problems, and take appropriate action. Team leadership is popular because it identifies the functions that a leader can share within the team.

For this Discussion, reflect on the leadership approaches or theories you have discussed throughout this course, select one of the approaches or theories that appeals to you. Consider the characteristics of your selected approach or theory. Consider the characteristics of Authentic Leadership and of Team Leadership.

By Day 3
Post a description of the approach or theory you selected. Compare the characteristics of the approach or theory you selected to those of Authentic Leadership and Team Leadership. Using your own experience, share an example of a situation that demonstrates this relationship. Describe the impact of that relationship. Use an example from your personal experience with this type of leadership or one from the Learning Resources.

Q1：LDA Parameter Tunning

Define a function tune_lda() as follows:

Takes two file name strings as inputs: train_f ile is the file path of text_train.json, and test_f ile is the file path of text_test.json

Fits LDA models (from gensim package) using documents from train_f ile with different parameter values:

Number of clusters (K ) from 2 to 6

Topic distribution prior (i.e. α): ‘symmetric’ (i.e. α = [1, 1, 1, . . . ] ), ‘asymmetric’ (i.e.

α = [1/K, 1/K, 1/K, . . . ] ), and ‘auto’ (i.e. the prior is calculated based on word frequency)

With all parameter combinations, in total, you’ll train 15 LDA models. When fitting each model, set the maximum number of iterations to 40 to make sure your model converges. Note, it may take a few minutes to train all models.

For each model, calculate topic coherence using ‘u_mass’ formula. The details of coherence can be found at https://radimrehurek.com/gensim/models/coherencemo…(https://radimrehurek.com/gensim/models/coherencemo…). Read the paper referenced in the link to make sure you understand the meaning of topic coherence. Note, ‘c_v’ instead of ‘u_mass’ is recommended to evaluate topic coherence. For simplicity, let’s use ‘u_mass’ here. However, if you can figure out how to use ‘c_v’, that’s even better.

Create a plot to show how topic coherence changes as the K increases under different α values (i.e., a line for each α value).

Based on the plot, determine best K and α values in terms of topic coherence

This function does not have a return. Write a document to show:

best parameter combination in terms of topic coherence

do you think topic coherence is a good metric for you to choose K ?

Training Theories

/in /by

Imagine that you work for a global automobile manufacturer as a lead training and development associate. The head of human resources (HR) has had meetings with various departments, and a training need was identified by the sales department. Sales have dropped considerably in the last quarter, and through a training needs analysis, it was shown that sales associates lack the proper knowledge, skills, and abilities (KSAs) to effectively sell automobiles to various car dealerships in the United States and abroad.

The head of HR has asked that you give him or her a presentation on which major training theory you would recommend to apply to this scenario to equip the sales associates with the necessary skills to increase sales.

Select one training theory. This can be any of the four discussed in this unit or a training theory of your choice that interests you. Then, in your PowerPoint presentation, include the elements listed below.     

        Discuss the training theory and its primary tenets.
        Explain why you recommend this theory.
        Discuss two to three activities that you would build from this theory. For example, if you chose action theory, you may create group activities where sales associates run through sales scenarios with each other to see what works and what does not. Feel free to be as creative as you would like with your given theory.
        Explain how your activities will address each learning style (i.e., visual, audible, and kinesthetic learning styles).

You are required to use at least one outside source and to utilize the notes section within PowerPoint. Within the notes section, include additional explanations for each slide. As you create your presentation, keep in mind that you are presenting for executives at your organization. All sources used, including the required unit resources, must be cited and referenced according to APA guidelines.

**Note: Please use the Unit Lesson (attached) for training theories and scholarly sources you will need to use on the PowerPoint**
