Balanced and Imbalanced GKA schemes Clause Samples

Balanced and Imbalanced GKA schemes. Balanced and Imbalanced is another classification method of GKA schemes except for the PKI-based, ID-based and certificateless-based schemes introduced above. The concept of balanced and imbalanced is come from the wireless network domain. One way to categorize different kinds of wireless networks is to classify them into balanced and imbalanced wireless network. In the balanced network, all nodes have the same level of computing power. In imbalanced wireless network, there are two classes of nodes: low power node(like smartphone in mobile network) and powerful node(like servers in mobile network), where powerful nodes have a much higher computation level. In the group key management domain, the concept of “imbalanced” is similar to the group key distribution schemes: One high-level key management server calculates the group key and distributes it to all group members. The concept of “balanced” is similar to the group key agreement schemes: all group members make the same contribution to the group key. Based on the similarity of the concept between balanced wireless network and group key agreement scheme, it seems that all group key agreements schemes should be balanced schemes. However, there could be a hybridization of group key distribution scheme and group key agreement scheme. In this hybridization scheme, all group members make contributions to the group key, but one of them might make more contribution or perform major parts of computation. This kind of hybridization scheme cannot be classified into key distribution scheme since the group key is not only generated by one powerful node, but it can be classified into key agreement scheme since the group key is generated by all members. Therefore, the concept of balanced and imbalanced can be used in the group key agreement domain. The group key agreement schemes can be classified into balanced and imbalanced GKA scheme, and the concept of imbalanced GKA scheme is the same as the hybridization scheme mentioned above. The GKA scheme from Nam et al. in 2005 [84] first shows the idea of imbalanced GKA scheme, because it considers the environment of mobile network, which is definitely a kind of imbalanced wireless network. However, ▇▇▇▇▇ criticized that ▇▇▇’s scheme lacks contributory property because the group members cannot confirm their contribution to the group key in his scheme, then ▇▇▇▇▇ proposed his own scheme[85]. Unfortunately, ▇▇▇ et al. pointed out that ▇▇▇▇▇’▇ scheme lacks authentication and c...

  • LAYOFFS AND RECALLS (a) Employees will be laid off in reverse order of seniority whenever there is a reduction of employees in the bargaining unit. The only exception to this provision is when the client requests in writing that a specific security guard be retained at their site. Guards can bump due to (1) loss of site, (2) being bumped by a senior guard, (3) client removal for non-disciplinary reasons, (4) return from approved leave of absence or (5) loss of position on a site. (b) The Company shall notify employees whose position is to be eliminated due to the loss of work at a specific site or the loss of the entire site at least five (5) working days prior to the effective date of termination of the position. Such employee will be entitled to bump junior employees at other sites in order to maintain employment and status. The company will meet with the affected employee and their Union representative as quickly as possible after notification in order to allow the employee to review options and make an informed decision where they wish to bump into. The parties will attempt to place the security guard into an alternate site where said guard will not lose any days of pay, but in no event, will the placement, or bumping take more than five (5) working days (no more than five (5) unpaid days). If an employee is not slotted into their new position within said five (5) working days, the company will provide payment in lieu of work. During the up to five (5) days waiting period, the employee will be entitled to be on top of the spare board list if they so desire. (c) The Company shall generally give notice of recall by registered mail to the last recorded address of the employee. The employee shall keep the Company informed of the employee's present address of location where he may be reached. The employee who fails to do so shall forfeit his right of recall. (d) If, within one (1) calendar day from the receipt of such notice, the employee accepts the recall, the job will be held open for one (1) calendar day from the day of the employee's acceptance. In the event that such recalled employee is employed elsewhere at the time of recall, the Company will hold the position vacant for two (2) weeks if the Company has received appropriate advance notice from its client. (e) In circumstances where the Company must fill vacant positions without delay, the Company shall give notice of recall by telephone until able to find a qualified employee who is prepared to report to work immediately. (f) If the employee declines the position, or fails to respond to the notice within one (1) calendar day from the date of receipt of the original notice, or fails to report to work within the time period outlined above, such employee shall be considered to have resigned and shall forfeit his recall rights. Should such employee be prevented from returning to work due to illness or accident he shall retain his recall rights and the Company shall be at liberty to recall another employee. The employee shall be required to show proof of such illness or accident.

  • LAYOFFS AND RECALL 16.01 It is not the intent of these lay-off and recall procedures to apply to the normal summer period. However, where known, recall dates of ten (10) month employees shall be indicated on the Separation Certificate issued by the Employer. 16.02 In the event of lay-off, employees shall be laid off in reverse order of their seniority provided that those persons retained have the necessary skills, qualifications, and ability to perform the duties of those jobs maintained. a) In order to minimize the potentially disruptive nature of an Educational Assistant lay-off during the school year, an Educational Assistant who has received a lay-off notice during the school year may elect to: i) Accept the lay-off and be recalled under the terms of the Collective Agreement or; ii) Displace the most junior permanent Educational Assistant in the Division. b) Where there are Educational Assistants who are on lay-off or who are laid off at the end of June, and there will not be sufficient positions in September for them all to be recalled, then the Employer will lay-off a sufficient number of the most junior Educational Assistants so as to enable the more senior Educational Assistants to be recalled in September. c) Educational Assistants who receive a lay-off notice must declare their intention to displace a junior Educational Assistant within the first five (5) working days of receipt of the lay-off notice. It is agreed between the parties that failure to do so will mean that the Educational Assistant accepts lay-off at the end of the notice period. 16.03 Employees shall be recalled in order of their seniority provided that the person recalled has the necessary skills, qualifications, and ability to perform the duties of the job. 16.04 New employees shall not be hired if there are employees on lay-off with the necessary skills, qualifications, and ability to perform the work. 16.05 In the event of lay-off, every employee affected shall be given four (4) weeks’ notice before the date on which she is to be laid off, and to the extent that such minimum notice is not given, the employee shall receive pay in lieu thereof. 16.06 Grievances concerning lay-offs and recalls shall be initiated at Step II of the grievance procedure. 16.07 Notwithstanding the provisions of Article 15.01, an Educational Assistant who normally works twenty-seven and one-half (27 ½) or more hours per week, and whose hours of work have been unilaterally reduced during the school year, shall, at the Educational Assistant’s option, be deemed to have been laid off. An Educational Assistant accepting a position having fewer hours than their normal working day will be given primary consideration upon application when new positions become available having comparable hours. 16.08 All Educational Assistants laid off shall be placed on a recall list, with copy furnished to the Union, and shall be called back to work as required beginning with the most senior Educational Assistant and descending from there. 16.09 No Educational Assistant shall be permitted to have her name remain on the recall list in excess of twelve (12) school months following the month in which the layoff occurred.

  • COMPLAINT AND GRIEVANCE PROCEDURE 9.01 Where a difference arises between the parties relating to the interpretation, application or administration of this Agreement, including any questions as to whether a matter is arbitrable, or where an allegation is made that this Agreement has been violated or whenever an employee who has completed the required probationary period and has been accepted by the Employer for employment in the permanent service, claims that he/she has been disciplined or discharged without reasonable cause, such difference, allegation or claim being hereinafter referred to as the grievance, the grievance procedure set forth below shall apply. 9.02 The Association shall name, appoint or otherwise select a Grievance Committee of no more than three (3) who shall be members of the Association and shall have reached at least the rank of First Class Fire Fighter and other advisors as deemed necessary at the expense of the Association. The Employer shall recognize and deal with the Grievance committee with respect to any matter or dispute which properly arises from a breach of the Collective Agreement from time to time during its term. This committee shall suffer no loss as a result of their attendance at such grievance meetings, hearings, etc. 9.03 No grievance will be considered where the circumstances giving rise to it occurred or originated more than ten (10) full working days before the submission of the grievance. Step 1 - An employee having a grievance will take the matter up through their Association representative. The President or designate shall contact Fire Management to seek a resolution. Step 2 - If the grievance is not settled within five (5) working days, the Association shall submit the matter in writing to the Fire Chief or designate within five (5) working days of receiving the reply from Step 1. The Fire Chief or designate shall render the written decision to the Association within five (5) working days after receiving the written grievance. In the context of this Article a working day shall be deemed to be Monday to Friday excluding designated holidays. Step 3 - If the reply of the Fire Chief is not acceptable to the Association the grievance may be referred to the Chief Administrative Officer (CAO) or the Director of Human Resources within five (5) working days of the written decision of the Fire Chief. The CAO or the Director of Human Resources, who together with the Fire Chief and any other advisors deemed necessary, shall meet with the Association Representatives within 5 working days to consider the grievance. Within five (5) working days of the aforesaid, the CAO or the Director of Human Resources will render a written reply to the employee and the Association. Step 4 - If no resolve is reached at Step 3, the matter shall be submitted to arbitration. Notice shall be given within 5 business days. The parties agree that, for the purposes of this collective agreement the words of the expedited arbitration provisions of the Labour Relations Act, 1995 as amended (Section 49), will be deemed to have been incorporated into this collective agreement. Accordingly and notwithstanding any other provisions of this article (the grievance/arbitration provisions); either party may refer a grievance to expedited arbitration in accordance with the provisions of Section 49. The parties further agree that neither party will raise any jurisdictional or other objection to the application of Section 49 to a grievance under this collective agreement as it pertains to the right to an expedited arbitration. Either party is entitled however, to raise any objection, with the arbitrator with respect to whether the provisions of Section 49 have been properly utilized in respect of any specific grievance (e.g. objections with respect to time limits etc.).
